Abstract

Objectives: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex chronic and debilitating multifactorial disease. Adequate patient care is challenged by poor knowledge among health care professionals and the historical misconception that the disease is psychological in nature. This study assessed the health-related challenges faced by patients with ME/CFS in Switzerland and examined whether they receive adequate health care. Methods: Quantitative and qualitative data were collected through a self-administered questionnaire between June and September of 2021, among 169 patients with ME/CFS in Switzerland. Results: The mean age at diagnosis was 38.8 years. Only one-third of ME/CFS affected children and youth were correctly diagnosed before their 18th birthday. The mean time from disease onset to diagnosis was 6.7 years, and patients had an average of 11.1 different appointments and 2.6 misdiagnoses. A poor diagnosis rate and insufficient disease knowledge among health professionals in Switzerland led 13.5% of the patients to travel abroad to seek a diagnosis. Most patients (90.5%) were told at least once that their symptoms were psychosomatic. Swiss patients expressed high dissatisfaction with the health system and indicated that physicians lacked knowledge regarding ME/CFS. Therapies prescribed by physicians or tried by patients, as well as their perceived efficacy, were described. Graded Exercise Therapy (GET) was perceived as harmful by patients, whereas pacing, complementary/alternative medicine, and dietary supplements and medications to alleviate symptoms were reported to be helpful to varying degrees. Conclusion: This study highlights that poor disease knowledge among health care providers in Switzerland has led to high patient dissatisfaction, and delays in ME/CFS diagnoses and prescription of inappropriate therapies, thus adding to patient distress and disease burden.

Introduction
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/
CFS) is a multifactorial, complex, chronic, stigmatizing,
physically debilitating disease whose etiology remains
unknown.
1
It simultaneously affects multiple systems of the
body in response to triggers. Several factors have been
associated with disease onset, such as infectious diseases,
autoimmune dysfunction, extreme stress, underlying genetic
predisposition, receptor dysfunction and toxins.
2e6
The
disease lasts more than 6 months but is often lifelong, and is
characterized by severe debilitating fatigue, post-exertional-
malaise, sleep disturbance, cognitive impairment, pains, and
other immunological, neurological and endocrinological
symptoms associated with the affected body
system.
7,8
Dysregulation of the immune system is a key feature
of ME/CFS, as indicated by elevated inflammatory and
immune processes and chronic neuro-
inflammation.
3,7,9,10
Other key features of the disease
include decreased metabolism and impaired mitochondrial
functions.
7
Infectious diseases, particularly viral diseases, are
believed to play important roles in disease onset and/or
shaping the disease course.
11
Symptoms are exacerbated by
triggers, including physical and mental activities or stress,
thus leading patients to experience so-called crashes, from
which recovery is very slow.
12,13
ME/CFS is often overlooked and historically was long
misclassified by physicians as a psychosomatic or psycho-
logical disease.
14
Consequently, patients were not provided
with adequate care, help or support.
15
Despite the large
existing body of scientific evidence on the physical
pathologies of ME/CFS, many health care workers still
lack knowledge or the disease, and most still believe in a
psychological underlying cause, as indicated by a recent
audit performed in hospitals in the UK (Hng et al., 2019).
In the US, more than 80% and 90% of adult and child
patients, respectively, have been estimated to remain
undiagnosed.
16,17
Generally, patients report poor
satisfaction with provided medical care.
18,19
Several factors
and barriers are regularly associated with poor health care
provision for ME/CFS. First, few physicians are
knowledgeable regarding the disease.
20,21
Timbol and
Baraniuk
22
have reported that patients with ME/CFS
admitted to the emergency department in the US for
predominantly cardiovascular problems (e.g., orthostatic
intolerance) have indicated that physicians attributed their
symptoms to stress, anxiety or psychological issues, and
had poor to no knowledge of ME/CFS. Patients must
travel long distances to find specialists
19,23
and usually
attend several appointments before a diagnosis is
made.
20,21
Moreover, financial barriers exacerbate the lack
of access to health care provision.
19,23,24
To our knowledge, Switzerland currently has no scientific
data on ME/CFS in its population. A meta-analysis by Lim
et al.
25
has estimated a pooled prevalence of ME/CFS of
0.4%, which would translate to at least 34,000 people with
ME/CFS in Switzerland, which is comparable to the
number of people with other recognized diseases, such as
multiple sclerosis.
26
In light of the globally poor disease
knowledge among medical professionals, we asked whether
the population with ME/CFS in Switzerland is receiving
adequate health care. To answer this question, we
conducted a preliminary epidemiological survey among
patients with ME/CFS. Herein, we present the health care
provision to patients with ME/CFS, on the basis of
quantitative and qualitative data.
Materials and Methods
Study design and participants
This study was part of a larger cross-sectional study
performed between June and September of 2021 in
Switzerland, including 169 patients with ME/CFS who were
18 years of age or older, who were recruited through the
largest Swiss ME/CFS association (Tschopp et al., submit-
ted). Purposive sampling was used. All members of the na-
tional Swiss ME/CFS association were informed of the study
(e.g., through mailing lists, newsletters, websites and direct
information provided during association meetings). Detailed
information on the study, the questionnaire and the consent
form was sent individually by mail to all people willing to
participate in the study. Written informed consent was
requested from all participants. Completed questionnaires
and consent forms were returned with a pre-stamped return
envelope.
Questionnaire survey
A paper questionnaire survey was self-administered by
participants, because of the ongoing COVID-19 pandemic.
R. Tschopp et al.2

Sciences, https://doi.org/10.1016/j.jtumed.2022.12.019
Respondents were able to answer questions at their own
pace, given that responding to the questionnaire might
potentially have been exhausting.
Each questionnaire was coded with a unique numerical
ID number. The questionnaire was prepared in German and
French, and was pre-tested with four patients with ME/CFS
who did not participate in the survey, to ensure that the
questions were well designed and well understood. Questions
in the overall questionnaire included closed and open ques-
tions on the following topics: general demography, disease
history, therapies, socio-economic impact of the disease,
coping mechanisms and ME/CFS during the COVID-19
pandemic. Participants were invited to provide in depth,
detailed or additional information about their disease that
was not captured in the questionnaire.
Data management and statistical analysis
Questionnaire data were entered into Microsoft Access
and analyzed in STATA software version 16.1 (StataCorp
LLC, USA). Descriptive statistical analysis was used to
analyze the study population data and perform group com-
parisons. A p-value <0.05 was considered statistically sig-
nificant. Additional qualitative data collected in the
questionnaire as open-ended questions were entered into
Microsoft Excel and analyzed descriptively, and are reported
as illustrative quotations. Qualitative data from the open-
section were analyzed thematically.
Results
ME/CFS diagnosis
The mean age at diagnosis was 38.8 years (95% CI: 36.9e
40.7; SE ¼0.95). Half the patients were diagnosed between
the ages of 25 and 44 years (51.6%). None of the young
children (6e12 years) were diagnosed while being in their age
category, and only one-third (N ¼8/24; 33.3%) of all chil-
dren and youths with ME/CFS were diagnosed before their
18th birthday (see Table 1).
The mean time from disease onset to final ME/CFS
diagnosis by physicians was 6.7 years (95% CI: 5.5e7.9;
SE ¼0.60).
General practitioners (GPs) and specialists were both
involved in diagnosis (often in combination). Among the
138 patients diagnosed by specialized physicians, the
following top three medical specialties were described:
physicians in clinics specializing in general medicine
(N ¼47; 34%), psychiatrists (N ¼45; 32.6%) and neurol-
ogists (N ¼35; 25.4%). Other specialties described were
internists (N ¼19; 13.8%), physicians in psychosomatic
medicine (N ¼16; 11.6%), psychologists (N ¼15; 10.9%),
immunologists (N ¼14; 10.1%), cardiologists (N ¼5;
3.6%), pediatricians (N ¼2; 1.4%), physicians in tropical
medicine (N ¼1; 0.7%) and others (N ¼22; 15.9%). No
statistical differences were observed among patient genders
or the types of specialists providing the diagnosis. Twenty-
one patients (13.5%) sought treatment abroad (Germany,
the Netherlands, United Kingdom, Austria, South Africa
or USA) after no physician in Switzerland was able to
provide a diagnosis. Therefore, these patients received an
ME/CFS diagnosis from clinics and/or health specialists
abroad.
Before receiving their ME/CFS diagnosis, patients
visited an average of 11.1 physicians (95% CI: 9.4e12.9;
SE ¼0.86) and received a mean of 2.6 other diagnoses (95%
CI: 2.1e3.1), primarily mental health conditions (e.g.,
depression or psychosomatic disease), burn-out or neuras-
thenia. A total of 90.5% of patients were told at least once
before their final ME/CFS diagnosis that their symptoms
were psychosomatic.
A total of 115 patients described how they felt when they
received their ME/CFS diagnosis. Most of them experienced
a sense of relief in finally knowing their diagnosis (N ¼84;
73%), whereas 24 (20.9%) had negative feelings of sadness,
hopelessness or anxiety because of the poor prognosis, and a
loss of hope for healing, given the lack of available therapies
and support. The diagnosis of ME/CFS led some patients to
have less stress and anxiety (N ¼3); to experience a feeling of
finally being taken seriously (N ¼2); and to stop fighting the
symptoms, and learn to accept and cope with them (N ¼4).
Furthermore, the diagnosis enabled patients to focus on
healing, to adjust to a new lifestyle (N ¼1) and to be able to
explain their condition to others. After having a name for the
disease, patients were able to research the disease on the
internet and in books.
Patients’ feelings toward provided medical care
Most patients found physicians understanding and sup-
portive (N ¼112; 66.3%), whereas 106 and 63 patients stated
that physicians were arrogant and disparaging, respectively.
Sixty-five described “other” behaviors, such as physicians
being helpless and overwhelmed (N ¼12), not believing
patients (N ¼4), having no knowledge of the disease (N ¼8),
being prejudiced (N ¼1), being annoyed with patients
(N ¼3), showing no interest (N ¼2), humiliating patients
(N ¼1) and categorizing (N ¼1).
During the entire disease period, including pre-diagnosis,
patients left medical appointments with negative feelings
three times more often than with positive ones (e.g., feeling
happy, hopeful or taken seriously). Negative feelings were
reported by 113 patients who said that they were often not
taken seriously, 92 who felt hopeless, 86 who felt desperate,
60 who felt humiliated and 59 who felt ignored.
Of 168 patients, only two described the medical service
regarding ME/CFS as good, whereas 38 (22.6%) and 129
(76.8%) considered it bad and very bad, respectively. Only
16% (N ¼27) of respondents thought that physicians had
sufficient knowledge regarding ME/CFS. Table 2 highlights
quotations from participants regarding their feelings
toward the provided health care.

angry and frustrated. They have to learn
to see patients as collaborators and not
enemies.” (Female, 47, ZH)

“If I had money, I would go abroad to a
good doctor.” (Female, 59, LU)
“One of the first diagnoses was burn-out;
doctors asked me then to do a lot of
sports, which worsened my symptoms
terribly. Then around ten doctors said it
was psychosomatic, and I was sent to the
psychiatrist, who said I was mentally
healthy, and it was somatic, and I was
sick. Then I was finally diagnosed with
ME/CFS by a CFS specialist.” (Male,

“I gave up going to physicians in
Switzerland, I went to London, where
I was diagnosed with ME/CFS. Back
in Switzerland, I shared the report with
my doctor, who said that CFS did not
exist.” (Female, 51, AG)
“Being taken seriously by a doctor
helped me to carry the burden caused by
the disease.” (Male, 38, BE)
“Previously, I was mis-diagnosed as
having psychosomatic issues and sent to
a rehabilitation clinic. I had to do a lot of
group activities to foster communication,
as well as aggressive massages and lots of
fitness. I had to stop, as I was getting
sicker and sicker.” (Male, 51, VS)
“It was a relief to know what is wrong
with me after 31 years, and understand
my symptoms.” (Female, 46, LU).
“It is important for GPs to know the
disease, because private clinics are too
expensive for follow-ups.” (Female, 46,

“I was sent to a psychosomatic
rehabilitation clinic. They made me do
plenty of sports, which ultimately
harmed me. I went into a three month
crash afterwards. Nobody knew about
ME/CFS there.” (Male, 44, AG)

after 10 years of being told it was all in
my head, I really started believing I
was mad.” (Female, 33, ZH)
“The specialist who diagnosed me is too
far away; it is impossible to do follow-
ups.” (Male, 69, AG)
“I went to a psychosomatic
rehabilitation clinic, where I had to do a

Reported therapies
Before diagnosis, the most frequently prescribed inter-
vention by medical professionals (N ¼93) was treatment for
depression (N ¼93), regardless of patient gender (no sta-
tistical difference). In contrast, the top recommendations
from physicians who had properly diagnosed patients with
ME/CFS were primarily associated with energy conservation
strategies (N ¼78). The following strategies were also rec-
ommended by physicians (before and after diagnosis):
nutrition (N ¼48), medication to alleviate some of the
symptoms (N ¼39), pain management (N ¼34) and a focus
on mental health/wellness (N ¼27). Patients, in contrast,
prioritized energy conservation techniques (N ¼301), a focus

on mental health/wellbeing (N ¼111), nutrition (N ¼96)
and pain management (N ¼50).
Figure 1 shows a tree chart with the recommendations
made by physicians during the entire duration of illness
(pre and post diagnosis) and compares the strategies used
by patients after diagnosis with ME/CFS.
We investigated the efficiency of the reported treatment
strategies. Table 3 shows the therapies tried by all
participants at least once during the course of illness. The
number of therapies tried by our patients with ME/CFS
ranged from 1 to 11 (mean: 6.5; 95% CI: 6.2e6.9; SD: 2.2),
and 82% of the participants reported trying multiple
therapies.
Figure 2 shows the average efficiency of each strategy,
which was assigned a score with the following scale:
5¼helped a lot, 4 ¼helped moderately, 3 ¼helped a bit,
2¼did not help and 1 ¼was harmful. Only pacing,
medication to alleviate symptoms, alternative medicine and
dietary supplements helped, on average, whereas GET was
reported to have been harmful.
Participants reflected, in their own words, on the therapies
that they received (Table 2).
Discussion
Although ME/CFS is diagnosed by exclusion of a broad
spectrum of possible etiologies and follows international
diagnostic guidelines, the lack for improved acknowledge-
ment and expertise in ME/CFS among physicians in
Switzerland is highlighted by the latency between the onset of
disease and establishment of a diagnosis (approximately 7
years). Given that more than 80% of patients remain undi-
agnosed,
27e29
this delay is likely to be an under-estimation.
Our results suggest that children are at particular risk of
remaining undiagnosed and consequently are exposed to mis-
management. Pediatric ME/CFS, which has an estimated
prevalence between 0.1% and 0.5% (Rowe et al., 2017) has
long lasting effects on children, e.g., high dropout rates in
school, limited access to education and entry into adulthood
with chronic disease. The peak age of disease onset in pedi-
atric ME/CFS is between 11 and 19 years.
30e32
Hence,
pediatricians’ awareness of the negative effects of this
disease must be addressed, and referral strategies with
sensitization for early symptoms must be established.
In our study, only two pediatricians among the 24 pedi-
atric patients provided an ME/CFS diagnosis. Overall, one-
third of the diagnoses were made by general medicine phy-
sicians or psychiatrists, and one-quarter were made by neu-
rologists. Only 10% of respondents were diagnosed by an
immunologist, although the disease is known to have major
immunological components.
3,10,33
ME/CFS appears to
remain poorly recognized among many medical experts and
specialists in Switzerland; thus, better awareness among
health professionals is urgently warranted. On average,
more than 11 different appointments were required, and
several misdiagnoses were made to establish a conformed
diagnosis of ME/CFSdsubstantially more than previously
reported in studies from other countries. Sunnquist et al.
23
have observed an average of four or more appointments in
the USA until diagnosis, and only 11.5% of the patients
with ME/CFS being treated and managed by adequate
specialists. Before the diagnosis, more than 90% of
enrolled patients in our study were told at least once that
their disease was of psychological nature and received
inadequate management. This result is in line with findings
from a recent audit performed in the UK showing that
91% of the health care providers considered ME/CFS at
least partly psychological and demonstrated poor overall

disease knowledge.
34
Swiss patients with ME/CFS have
therefore developed mistrust of, and resentment toward,
psychologists/psychiatrists. Interestingly, however, one-
third of the ME/CFS diagnoses were actually provided by
psychiatrists who rejected the psychological etiology under-
lying the specialists’ referrals and instead identified a somatic
health problem.
Health service provision was considered poor by patients:
only two of 168 patients stated that they felt adequately
managed, whereas 16% described that their physician dis-
played knowledge regarding ME/CFS. Overall, during their
entire time of living with the disease (pre and post diagnosis),
patients experienced negative feelings (desperation, not being
taken seriously, and feeling hopeless, humiliated or ignored)
three times more often than positive feelings after their
medical appointments. The poor diagnosis success rate in
Switzerland discouraged 13.5% of the study population from
traveling abroad and seeking diagnosis elsewhere.
Others sought online medical support, such as therapy
guidance with ME/CFS experts abroad, in countries where
ME/CFS is recognized and better known among physicians.
Patients with ME/CFS with high dissatisfaction with the
provided medical care have also been reported from Ger-
many, the UK and the US.
19,21e23
Although experts in ME/
CFS exist, they are few. Most physicians and health care
providers in Switzerland have limited knowledge of the
disease, as also reported in other studies.
21,22,34
Some
additional described barriers to heath care in our study,
were the lack of house visits by GPs for house or bed-
bound patients; the remoteness of specialized physicians,
thereby making access difficult for patients with ME/CFS;
and the difficulty in receiving follow-up care after diagnosis
because of the high cost of private clinics. Poor overall dis-
ease knowledge was also reflected in the therapies recom-
mended by physicians to patients. Before diagnosis, 93
patients received recommendations for treatment for
depression (e.g., use of anti-depressants or psychiatrist sup-
port), which patients perceived as harmful. Post-exertional
malaise and the pathology of ME/CFS, involving down-
regulation of the hypothalamicepituitaryeadrenal axis and
impairment of the central and autonomous system, differ
from pathologies causing depression
35
; Morris et al., 2007).
Of particular concern, psychotropic medications prescribed
for mood disorders and depression have shown detrimental
effects on mitochondrial functions through, e.g., decreased
carnitine availability, and impaired respiratory chain and
ATP production.
36e38
Mitochondrial impairment is a key
feature among patients with ME/CFS. Such medications
can therefore aggravate pre-existing impairments and
worsen symptoms. Patients were encouraged to increase their
physical activity or were sent to rehabilitation clinics in
which promoting physical activity was among the core
treatments. Those patients reported severe worsening of their
illness, sometimes to dramatic levels (e.g., months-long
crashes or being wheelchair bound). Of all types of therapy
attempted by patients, GET was the only one reported to
have harmful effects. Compelling scientific evidence has now
indicated the pathways and pathological mechanisms un-
derlying muscular fatigue and pains, as well as the neuro-
immunological impairment triggered by physical activity;
these findings support the counterproductive and harmful
effects of GET in patients with ME/CFS.
15,39,40
Until
dissemination of the available robust evidence indicating
that GET is detrimental and should no longer be used in
treating patients with ME/CFS, the misconception of
physical activity being beneficial in ME/CFS will remain
anchored in the psychosomatic dogma widely held by
health care providers.
41,42
After being properly diagnosed with ME/CFS, patients
received recommendations by their physicians to follow “en-
ergy-saving strategies.” Our study also indicated that pacing
was perceived by the respondents to be the most effective
strategy for alleviating some of the symptoms, beyond medi-
cations, complementary alternative medicine and diet. Nutri-
tional supplements in ME/CFS have shown little evidence of
benefit in the scientific literature,
43
although the current
evidence is insufficient to draw conclusions. The study
participants views on the efficacy of supplements were also
too heterogeneous to draw a conclusion; therefore, more
research is clearly warranted in this field. No approved
medical treatments are currently available for ME/CFS, and
no cure exists.
6
Our study showed that patients
independently tried several approaches to improve their
symptoms, with or without support from their physicians.
Supplements were commonly used (e.g., NADH, coenzyme,
vitamins and minerals) as well as approaches focusing on
pain relief (medication and alternative/complementary
medicine) and energy management (e.g., pacing and daily/
weekly energy management plans). Antiviral agents were
recommended in two patients, and one patient participated
in a clinical trial of an experimental drug. Antiviral agents
such as valaciclovir and valganciclovir have been described
to elicit some improvements in a small number of patients, in
whom EBV or HHP 6 were suspected as possible disease
triggers.
44e46
Therapeutic research and trials have focused
mainly on targeting immune modulation through the use of
antiviral agents, immunosuppressants, immunostimulation,
and mitochondrial support.
9,47e52
To date, rintatolimod, a
drug developed for cancer and aggressive viral infections,
which increases natural killer cell function and acts as a
TLR3 agonist, is the only drug that has been assessed
specifically for ME/CFS; however, it has not yet been
approved, except in Argentina.

The limitations of this study were those inherent to self-
administered questionnaire studies, including possible recall
bias. This study indicated that patients with ME/CFS in
Switzerland experience notable challenges in receiving
prompt diagnosis, adequate health care and support. The
disease may remain undiagnosed or mis-diagnosed for an
often unacceptable latency, which is associated with incor-
rect and sometimes harmful treatments. Swiss patients re-
ported high dissatisfaction with existing health care. The
study highlighted the lack of disease knowledge among
physicians. Because no diagnostic laboratory tests are
currently available, and no cure currently exists, improving
awareness and knowledge of ME/CFS among physicians and
health care providers is of paramount importance. In
Switzerland, an urgent need exists to improve the medical
care of patients with ME/CFS, and achieve better under-
standing and acceptance of the disease, ideally through

medicine training and continuing education.
If an adequate diagnosis can be made earlier in the disease
course, (i) a more reliable prospective evidence base could be
created to shape guidelines, inform healthcare policy and
provide a foundation for greater investment in research, and
(ii) adequate supportive treatment and correct management
could be initiated in a higher proportion of patients with
ME/CFS.

... In several studies (42)(43)(44)(45), various aspects of perceived care quality in specialist healthcare for ME/CFS patients have been evaluated, but they did not focus on the attention to PEM. In general, only a minority was satisfied with the obtained care and specialists' knowledge about ME/CFS. ...
... However, for majority of the ME/ CFS patients, a predominantly biomedical explanation of their disease usually fits their experiences better than a psychosomatic approach (32, 75, 76). Generally, many ME/CFS patients feel that the doctors psychologize too much, trivialize the symptoms, or tell them that their symptoms are psychosomatic (43,(77)(78)(79). If patients meet an opposing explanatory model in healthcare practice, negative patient experiences and dissatisfaction with received care may arise (75, 79). ...
... In our study, failure to address PEM led to ineffective, harmful healthcare and respondents reported poor disease understanding of ME/CFS among healthcare providers and a lack of validation of their illness experiences (see also Table 6). This has also been reported in previous studies (42,43,45,79,80). The high internal consistency of not addressing PEM and a reported approach that was poorly customized to ME/CFS suggests that these elements may measure a similar notion of viewing ME/CFS (58). ...

Background Post-exertional malaise (PEM) is considered a hallmark characteristic of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This may also apply to subgroups of patients with long COVID-induced ME/CFS. However, it is uncertain to what extent PEM is acknowledged in routine specialist healthcare for ME/CFS patients, and how this affects patient outcomes. Objective This study aims to evaluate to what extent ME/CFS patients experienced focus on PEM in specialist healthcare practice and its significance for outcome and care quality. Methods Data from two online cross-sectional surveys covering specialist healthcare services for ME/CFS patients at rehabilitation institutes in Norway and two regional hospitals, respectively, were analyzed. Evaluations of 788 rehabilitation stays, 86 hospital consultations, and 89 hospital interventions were included. Logistic regression models and Mann–Whitney U-tests were used to quantify the impact of addressing PEM on health and functioning, care satisfaction, or benefit. Spearman’s rank correlation and Cronbach’s alpha of focus on PEM with the respondents’ perception of healthcare providers’ knowledge, symptom acknowledgment, and suitability of intervention were assessed as measures for care quality and their internal consistency, respectively. Results PEM was addressed in 48% of the rehabilitation stays, 43% of the consultations, and 65% of the hospital interventions. Failure to address PEM roughly doubled the risk of health deterioration, following rehabilitation (OR = 0.39, 95% CI 0.29–0.52; 40.1% vs. 63.2% P = <0.001) and hospital intervention (OR = 0.34, 95% CI 0.13–0.89; 22.4% vs. 45.2%, p = 0.026). The focus on PEM (PEM-focus) during the clinical contact was associated with significantly higher scores on patients’ rated care satisfaction and benefit of both consultation and intervention. Furthermore, addressing PEM was (inter)related to positive views about healthcare providers’ level of knowledge of ME/CFS, their acknowledgment of symptoms, obtained knowledge, and the perceived suitability of intervention (Cronbach’s alpha ≥0.80). Discussion PEM is still frequently not acknowledged in specialist healthcare practice for ME/CFS patients in Norway. Not addressing PEM substantially increased the probability of a decline in health and functioning following the intervention and was strongly associated with reduced perceived care quality, satisfaction, and benefit. These findings may be related to the applied explanatory models for ME/CFS and are most likely of relevance to long COVID.

Patients who experience stigmatization and a lack of disease knowledge within society are forced to continually struggle for acceptance, understanding, and access to adequate medical care as shown in our previous study [12]. This uphill battle is often compounded by a lack of financial support. ...

Background Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating chronic disease of significant public health and clinical importance. It affects multiple systems in the body and has neuro-immunological characteristics. The disease is characterized by a prominent symptom called post-exertional malaise (PEM), as well as abnormalities in the immune-inflammatory pathways, mitochondrial dysfunctions and disturbances in neuroendocrine pathways. The purpose of this study was to evaluate the impact of ME/CFS on the mental health and secondary psychosocial manifestations of patients, as well as their coping mechanisms. Method In 2021, a descriptive cross-sectional study was conducted in Switzerland. A self-administered paper questionnaire survey was used to gather data from 169 individuals diagnosed with ME/CFS. Results The majority of the patients (90.5%) reported a lack of understanding of their disease, resulting in patients avoiding talking about the disease due to disbelief, trivialization and avoidance of negative reactions. They felt most supported by close family members (67.1%). Two thirds of the patients (68.5%) experienced stigmatization. ME/CFS had a negative impact on mental health in most patients (88.2%), leading to sadness (71%), hopelessness for relief (66.9%), suicidal thoughts (39.3%) and secondary depression (14.8%). Half of the male patients experienced at least one suicidal thought since clinical onset. Factors significantly associated with depression were the lack of cure, disabilities associated with ME/CFS, social isolation and the fact that life was not worth anymore with ME/CFS. The three main factors contributing to suicidal thoughts were (i) being told the disease was only psychosomatic (89.5%), (ii) being at the end of one's strength (80.7%) and (iii) not feeling being understood by others (80.7%). Conclusion This study provided first time significant insights into the mental and psychological well-being of ME/CFS patients in Switzerland. The findings highlight the substantial experiences of stigmatization, secondary depression and suicidal thoughts compared to other chronic diseases, calling for an urgent need in Switzerland to improve ME/CFS patient's medical, psychological and social support, in order to alleviate the severe mental health burden associated with this overlooked somatic disease.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a severe chronic illness and patients with ME/CFS are often medically underserved in Germany and other countries. One contributing factor is health professionals’ lack of knowledge about epidemiology, diagnostic criteria, and treatment of ME/CFS. Opportunities are scarce for health professionals to receive continuing medical education on ME/CFS. The current research addressed this need for further education and investigated the gain of knowledge from a webinar for German-speaking health professionals. In two studies (total sample: N = 378), participants in the intervention condition completed a knowledge test twice (before and after webinar participation). Study 2 also included a waiting-list control condition with repeated response to the knowledge test without webinar participation between measurements. Results showed that at baseline, most participants had seen patients with ME/CFS, but confidence in diagnosing and treating ME/CFS was only moderate-to-low. In the intervention condition, but not in the control condition, knowledge about ME/CFS increased between the first and the second knowledge test. These results indicate that the webinar was successful in increasing health professionals’ knowledge about ME/CFS. We concluded that webinars can be a cost-efficient and effective tool in providing health professionals with large-scale continuing medical education about ME/CFS.

Zusammenfassung Man geht bei der Myalgischen Enzephalomyelitis/dem Chronischen Fatigue-Syndrom (ME/CFS) von einer hohen Dunkelziffer aus. Ein Teil dieser undiagnostizierten Patient:innen vermutet, an ME/CFS zu leiden. Ziel dieser Studie war es zu ermitteln, ob und ggf. in welcher Hinsicht sich Erkrankte mit und ohne ärztliche ME/CFS-Diagnose unterscheiden. Dazu wurden die Antworten von 736 erwachsenen, ärztlich diagnostizierten ME/CFS-Erkrankten (DS1) mit denen von 189 erwachsenen Erkrankten ohne ärztliche ME/CFS-Diagnose (DS2) verglichen. Das Sampling erfolgte durch Selbstaktivierung/Schneeballprinzip. Nach einer deskriptiven Ergebnisdarstellung wurden potenzielle Zusammenhänge zwischen den verschiedenen Variablen untersucht (Pearson χ²-Test/Fisher’s Exact-Test, Levene-Test, t-Test). Beide Gruppen unterschieden sich nicht signifikant hinsichtlich Alter und Geschlecht. Die DS2-Kranken nahmen jedoch weniger ärztliche/alternativmedizinische Leistungen in Anspruch. Sie gaben weniger Symptome an, unterschieden sich jedoch nicht hinsichtlich ihres Symptomenspektrums. Im Gegensatz zur DS1-Gruppe nahm die Zahl der Symptome in der DS2-Gruppe nicht mit dem Alter ab, auch gab es hier keinen Geschlechtsunterschied. Anders als in Studien, die die Symptomhäufigkeit bei ME/CFS-Erkrankten mit Patient:innen vergleichen, die die kanadischen Konsensuskriterien (CCC) nicht erfüllen, ist die Differenz zwischen unseren beiden Gruppen deutlich geringer. Das führt zur These, dass zumindest ein Teil unserer nicht-diagnostizierten Proband:innen die CCC erfüllt. Eine Bestätigung dieser Hypothese könnte dazu führen, dass die Diagnosestellung bei dieser Patientengruppe in Zukunft früher geschieht, sodass früher Maßnahmen ergriffen werden können, die den Krankheitsverlauf positiv beeinflussen können.
... In Österreich und der Schweiz dauert es vom Auftreten der Symptome bis zur Diagnosestellung noch immer fünf bis acht bzw. knapp sieben Jahre, in der Schweiz müssen die Betroffenen mehr als elf verschiedene Ärzt:innen aufsuchen, bis die korrekte Diagnose gestellt wird [17,18]. Die Zufriedenheit mit der Versorgung ist unter den ME/ CFS-Erkrankten insbesondere dann gering, wenn die konsultierten Ärzt:innen nicht über das nötige Wissen hinsichtlich der Erkrankung verfügen. ...

Background: The disease ME/CFS is unknown to many doctors in Germany. Within the healthcare system, significant deficits in dealing with ME/CFS patients have been repeatedly revealed. Hence, the aim of the present study was to identify the specialties of the doctors consulted by ME/CFS patients and to find out whether information on the medical procedure in the context of the diagnosis process can be derived from this. Method: As part of the APAV-ME/CFS survey, the quantitative responses of 674 adult ME/CFS sufferers (>20 y.; 554 ♀, 120 ♂) who already had a medical ME/CFS diagnosis were statistically examined. The sampling was done by self-activation and via the snowball principle. The data were primarily evaluated descriptively. An analysis of variance was carried out to consider possible relationships. Results: Almost a quarter of the patients said they had suffered from ME/CFS for 6 to 10 years. Diagnosis was made within 10 years of disease onset in 62%. For 6.4% it took 21-40 years. 75% of the participants consulted 6 to 15 different doctors from a wide range of disciplines in the course of the disease, in particular from general medicine, neurology, internal medicine and psychosomatics/psychiatry. Diagnosis was made in particular by GPs and immunologists. On average, the test persons named 11 mostly neuroregulatory symptoms. Conclusions: The results suggest that in the context of finding a diagnosis in Germany for ME/CFS, referral behaviour to specialists based on single ME/CFS symptoms or rather arbitrary contacting of doctors from a wide variety of disciplines has prevailed so far. Therefore, training and further education measures on the subject of ME/CFS are urgently needed in all specialist disciplines in the resident, inpatient and rehabilitation sectors.
... Today, scientific papers portraying ME/CFS as psychosomatic continue to be published [59]. Many physicians still believe that ME/CFS is a psychosomatic disease [60], and 90% of patients with ME/CFS are at least once told by health professionals that their symptoms are psychosomatic before receiving an ME/CFS diagnosis [61]. In stark contrast to these widespread beliefs, empirical evidence does not support a psychosomatic etiology of ME/CFS [41]. ...

Since 1969, Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) has been classified as a neurological disease in the International Classification of Diseases by the World Health Organization. Although numerous studies over time have uncovered organic abnormalities in patients with ME/CFS, and the majority of researchers to date classify the disease as organic, many physicians still believe that ME/CFS is a psychosomatic illness. In this article, we show how detrimental this belief is to the care and well-being of affected patients and, as a consequence, how important the education of physicians and the public is to stop misdiagnosis, mistreatment, and stigmatization on the grounds of incorrect psychosomatic attributions about the etiology and clinical course of ME/CFS.
... Many people with ME and CFS have trouble accessing medical care, diagnosis, and treatment because of the widespread perception that their condition is psychological in origin. One research indicated that 71% of patients with ME/CFS consulted more than four doctors before getting an accurate diagnosis, and 63% of patients searched for a diagnosis for more than 2 years [3] . Ninety-five percent of women who sought medical help for CFS also reported feeling lonely [4] . ...

Multiple sclerosis (MS) and myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) share the symptom of fatigue, and might even coexist together. Specifically focusing on genetics, pathophysiology, and neuroimaging data, the authors discuss an overview of the parallels, correlation, and differences in fatigue between MS and ME/CFS along with ME/CFS presence in MS. Studies have revealed that the prefrontal cortex and basal ganglia regions, which are involved in fatigue regulation, have similar neuroimaging findings in the brains of people with both MS and ME/CFS. Additionally, in both conditions, genetic factors have been implicated, with particular genes known to enhance susceptibility to MS and CFS. Management approaches for fatigue in MS and ME/CFS differ based on the underlying factors contributing to fatigue. The authors also focus on the recent updates and the relationship between MS and sleep disorders, including restless legs syndrome, focusing on pathophysiology and therapeutic approaches. Latest therapeutic approaches like supervised physical activity and moderate-intensity exercises have shown better outcomes.

Background Myalgic encephalomyelitis/chronic fatigue syndrome is a chronic condition, classified by the World Health Organization as a nervous system disease, impacting around 17 million people worldwide. Presentation involves persistent fatigue and postexertional malaise (a worsening of symptoms after minimal exertion) and a wide range of other symptoms. Case definitions have historically varied; postexertional malaise is a core diagnostic criterion in current definitions. In 2022, a James Lind Alliance Priority Setting Partnership established research priorities relating to myalgic encephalomyelitis/chronic fatigue syndrome. Objective(s) We created a map of myalgic encephalomyelitis/chronic fatigue syndrome evidence (2018–23), showing the volume and key characteristics of recent research in this field. We considered diagnostic criteria and how current research maps against the James Lind Alliance Priority Setting Partnership research priorities. Methods Using a predefined protocol, we conducted a comprehensive search of Cochrane, MEDLINE, EMBASE and Cumulative Index to Nursing and Allied Health Literature. We included all English-language research studies published between January 2018 and May 2023. Two reviewers independently applied inclusion criteria with consensus involving additional reviewers. Studies including people diagnosed with myalgic encephalomyelitis/chronic fatigue syndrome using any criteria (including self-report), of any age and in any setting were eligible. Studies with < 10 myalgic encephalomyelitis/chronic fatigue syndrome participants were excluded. Data extraction, coding of topics (involving stakeholder consultation) and methodological quality assessment of systematic reviews (using A MeaSurement Tool to Assess systematic Reviews 2) was conducted independently by two reviewers, with disagreements resolved by a third reviewer. Studies were presented in an evidence map. Results Of the 11,278 identified studies, 742 met the selection criteria, but only 639 provided sufficient data for inclusion in the evidence map. These reported data from approximately 610,000 people with myalgic encephalomyelitis/chronic fatigue syndrome. There were 81 systematic reviews, 72 experimental studies, 423 observational studies and 63 studies with other designs. Most studies (94%) were from high-income countries. Reporting of participant details was poor; 16% did not report gender, 74% did not report ethnicity and 81% did not report the severity of myalgic encephalomyelitis/chronic fatigue syndrome. Forty-four per cent of studies used multiple diagnostic criteria, 16% did not specify criteria, 24% used a single criterion not requiring postexertional malaise and 10% used a single criterion requiring postexertional malaise. Most (89%) systematic reviews had a low methodological quality. Five main topics (37 subtopics) were included in the evidence map. Of the 639 studies; 53% addressed the topic ‘what is the cause?’; 38% ‘what is the problem?’; 26% ‘what can we do about it?’; 15% ‘diagnosis and assessment’; and 13% other topics, including ‘living with myalgic encephalomyelitis/chronic fatigue syndrome’. Discussion Studies have been presented in an interactive evidence map according to topic, study design, diagnostic criteria and age. This evidence map should inform decisions about future myalgic encephalomyelitis/chronic fatigue syndrome research. Limitations An evidence map does not summarise what the evidence says. Our evidence map only includes studies published in 2018 or later and in English language. Inconsistent reporting and use of diagnostic criteria limit the interpretation of evidence. We assessed the methodological quality of systematic reviews, but not of primary studies. Conclusions We have produced an interactive evidence map, summarising myalgic encephalomyelitis/chronic fatigue syndrome research from 2018 to 2023. This evidence map can inform strategic plans for future research. We found some, often limited, evidence addressing every James Lind Alliance Priority Setting Partnership priority; high-quality systematic reviews should inform future studies.

Zusammenfassung Myalgische Enzephalomyelitis/Chronisches Fatigue-Syndrom (ME/CFS) ist eine schwere, chronische Multisystemerkrankung, die je nach Ausprägung zu erheblichen körperlichen und kognitiven Einschränkungen, zum Verlust der Arbeitsfähigkeit bis hin zur Pflegebedürftigkeit einschließlich künstlicher Ernährung und in sehr schweren Fällen sogar zum Tod führen kann. Das Ziel dieses D-A-CH-Konsensusstatements ist es, 1) den aktuellen Wissensstand zu ME/CFS zusammenzufassen, 2) in der Diagnostik die kanadischen Konsensuskriterien (CCC) als klinische Kriterien mit Fokus auf das Leitsymptom post-exertionelle Malaise (PEM) hervorzuheben und 3) vor allem im Hinblick auf Diagnostik und Therapie einen Überblick über aktuelle Optionen und mögliche zukünftige Entwicklungen aufzuzeigen. Das D-A-CH-Konsensusstatement soll Ärzt:innen, Therapeut:innen und Gutachter:innen dabei unterstützen, Patient:innen mit Verdacht auf ME/CFS mittels adäquater Anamnese und klinisch-physikalischen Untersuchungen sowie der empfohlenen klinischen CCC zu diagnostizieren und dabei die präsentierten Fragebögen sowie die weiteren Untersuchungsmethoden zu nutzen. Der Überblick über die zwei Säulen der Therapie bei ME/CFS, Pacing und die symptomlindernden Therapieoptionen sollen nicht nur Ärzt:innen und Therapeut:innen zur Orientierung dienen, sondern auch Entscheidungsträger:innen aus der Gesundheitspolitik und den Versicherungen darin unterstützen, welche Therapieoptionen bereits zu diesem Zeitpunkt bei der Indikation „ME/CFS“ von diesen erstattbar sein sollten.

Background and Objectives: There is some evidence that knowledge and understanding of ME among doctors is limited. Consequently, an audit study was carried out on a group of hospital doctors attending a training event to establish how much they knew about ME and their attitudes towards it. Materials and Methods: Participants at the training event were asked to complete a questionnaire, enquiring about prior knowledge and experience of ME and their approaches to diagnosis and treatment. A total of 44 completed questionnaires were returned. Responses were tabulated, proportions selecting available options determined, 95% confidence limits calculated, and the significance of associations determined by Fisher’s exact test. Results: Few respondents had any formal teaching on ME, though most had some experience of it. Few knew how to diagnose it and most lacked confidence in managing it. None of the respondents who had had teaching or prior experience of ME considered it a purely physical illness. Overall, 82% of participants believed ME was at least in part psychological. Most participants responded correctly to a series of propositions about the general epidemiology and chronicity of ME. There was little knowledge of definitions of ME, diagnosis, or of clinical manifestations. Understanding about appropriate management was very deficient. Similarly, there was little appreciation of the impact of the disease on daily living or quality of life. Where some doctors expressed confidence diagnosing or managing ME, this was misplaced as they were incorrect on the nature of ME, its diagnostic criteria and its treatment. Conclusion: This audit demonstrates that most doctors lack training and clinical expertise in ME. Nevertheless, participants recognised a need for further training and indicated a wish to participate in this. It is strongly recommended that factually correct and up-to-date medical education on ME be made a priority at undergraduate and postgraduate levels. It is also recommended that this audit be repeated following a period of medical education.

Background and Objective: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a severe illness with the hallmark symptom of Post-Exertional Malaise (PEM). Currently, no biomarkers or established diagnostic tests for ME/CFS exist. In Germany, it is estimated that over 300,000 people are affected by ME/CFS. Research from the United States and the UK shows that patients with ME/CFS are medically underserved, as they face barriers to medical care access and are dissatisfied with medical care. The first aim of the current research was to investigate whether patients with ME/CFS are medically underserved in Germany in terms of access to and satisfaction with medical care. Second, we aimed at providing a German-language version of the DePaul Symptom Questionnaire Short Form (DSQ-SF) as a tool for ME/CFS diagnostics and research in German-speaking countries. Materials and Methods: The current research conducted an online questionnaire study in Germany investigating the medical care situation of patients with ME/CFS. The questionnaire was completed by 499 participants who fulfilled the Canadian Consensus Criteria and reported PEM of 14 h or longer. Results: Participants frequently reported geographic and financial reasons for not using the available medical services. Furthermore, they reported low satisfaction with medical care by the physician they most frequently visited due to ME/CFS. The German version of the DSQ-SF showed good reliability, a one-factorial structure and construct validity, demonstrated by correlations with the SF-36 as a measure of functional status. Conclusions: Findings provide evidence that patients with ME/CFS in Germany are medically underserved. The German-language translation of the DSQ-SF provides a brief, reliable and valid instrument to assess ME/CFS symptoms to be used for research and clinical practice in German-speaking countries. Pathways to improve the medical care of patients with ME/CFS are discussed.

Coronavirus disease 2019 (COVID-19) is a viral infection which can cause a variety of respiratory, gastrointestinal, and vascular symptoms. The acute illness phase generally lasts no more than 2–3 weeks. However, there is increasing evidence that a proportion of COVID-19 patients experience a prolonged convalescence and continue to have symptoms lasting several months after the initial infection. A variety of chronic symptoms have been reported including fatigue, dyspnea, myalgia, exercise intolerance, sleep disturbances, difficulty concentrating, anxiety, fever, headache, malaise, and vertigo. These symptoms are similar to those seen in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a chronic multi-system illness characterized by profound fatigue, sleep disturbances, neurocognitive changes, orthostatic intolerance, and post-exertional malaise. ME/CFS symptoms are exacerbated by exercise or stress and occur in the absence of any significant clinical or laboratory findings. The pathology of ME/CFS is not known: it is thought to be multifactorial, resulting from the dysregulation of multiple systems in response to a particular trigger. Although not exclusively considered a post-infectious entity, ME/CFS has been associated with several infectious agents including Epstein–Barr Virus, Q fever, influenza, and other coronaviruses. There are important similarities between post-acute COVID-19 symptoms and ME/CFS. However, there is currently insufficient evidence to establish COVID-19 as an infectious trigger for ME/CFS. Further research is required to determine the natural history of this condition, as well as to define risk factors, prevalence, and possible interventional strategies.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic debilitating disease characterized by severe and disabling fatigue that fails to improve with rest; it is commonly accompanied by multifocal pain, as well as sleep disruption, and cognitive dysfunction. Even mild exertion can exacerbate symptoms. The prevalence of ME/CFS in the U.S. is estimated to be 0.5-1.5% and is higher among females. Viral infection is an established trigger for the onset of ME/CFS symptoms, raising the possibility of an increase in ME/CFS prevalence resulting from the ongoing COVID-19 pandemic. Current treatments are largely palliative and limited to alleviating symptoms and addressing the psychological sequelae associated with long-term disability. While ME/CFS is characterized by broad heterogeneity, common features include immune dysregulation and mitochondrial dysfunction. However, the underlying mechanistic basis of the disease remains poorly understood. Herein, we review the current understanding, diagnosis and treatment of ME/CFS and summarize past clinical studies aimed at identifying effective therapies. We describe the current status of mechanistic studies, including the identification of multiple targets for potential pharmacological intervention, and ongoing efforts towards the discovery of new medicines for ME/CFS treatment.

Background: Cochrane recently amended its exercise review for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) in response to an official complaint. Objective: To determine if the amended review has addressed the concerns raised about the previous review and if exercise is an effective treatment that restores the ability to work in ME/CFS. Method: The authors reviewed the amended Cochrane exercise review and the eight trials in it by paying particular interest to the objective outcomes. We also summarised the recently published review of work rehabilitation and medical retirement for ME/CFS. Results: The Cochrane review concluded that graded exercise therapy (GET) improves fatigue at the end of treatment compared to no-treatment. However, the review did not consider the unreliability of subjective outcomes in non-blinded trials, the objective outcomes which showed that GET is not effective, or the serious flaws of the studies included in the review. These flaws included badly matched control groups, relying on an unreliable fatigue instrument as primary outcome, outcome switching, p-hacking, ignoring evidence of harms, etc. The review did also not take into account that GET does not restore the ability to work. Conclusion: GET not only fails to objectively improve function significantly or to restore the ability to work, but it's also detrimental to the health of≥50% of patients, according to a multitude of patient surveys. Consequently, it should not be recommended.

Introduction: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disease with high symptom burden, of unknown etiology, with no established treatment. We observed patients with long-standing ME/CFS who got cancer, and who reported improvement of ME/CFS symptoms after chemotherapy including cyclophosphamide, forming the basis for this prospective trial. Materials and methods: This open-label phase II trial included 40 patients with ME/CFS diagnosed by Canadian criteria. Treatment consisted of six intravenous infusions of cyclophosphamide, 600–700 mg/m², given at four-week intervals with follow-up for 18 months, extended to 4 years. Response was defined by self-reported improvements in symptoms by Fatigue score, supported by Short Form 36 (SF-36) scores, physical activity measures and other instruments. Repeated measures of outcome variables were assessed by General linear models. Responses were correlated with specific Human Leukocyte Antigen (HLA) alleles. Results: The overall response rate by Fatigue score was 55.0% (22 of 40 patients). Fatigue score and other outcome variables showed significant improvements compared to baseline. The SF-36 Physical Function score increased from mean 33.0 at baseline to 51.5 at 18 months (all patients), and from mean 35.0 to 69.5 among responders. Mean steps per 24 h increased from mean 3,199 at baseline to 4,347 at 18 months (all patients), and from 3,622 to 5,589 among responders. At extended follow-up to 4 years 68% (15 of 22 responders) were still in remission. Patients positive for HLA-DQB1*03:03 and/or HLA-C*07:04 (n = 12) had significantly higher response rate compared to patients negative for these alleles (n = 28), 83 vs. 43%, respectively. Nausea and constipation were common grade 1–2 adverse events. There were one suspected unexpected serious adverse reaction (aggravated POTS) and 11 serious adverse events in eight patients. Conclusion: Intravenous cyclophosphamide treatment was feasible for ME/CFS patients and associated with an acceptable toxicity profile. More than half of the patients responded and with prolonged follow-up, a considerable proportion of patients reported ongoing remission. Without a placebo group, clinical response data must be interpreted with caution. We nevertheless believe a future randomized trial is warranted.

Myalgic Encephalomyelitis or Chronic Fatigue Syndrome (CFS/ME) is a complex and severely disabling disease with a prevalence of 0.3% and no approved treatment and therefore a very high medical need. Following an infectious onset patients suffer from severe central and muscle fatigue, chronic pain, cognitive impairment, and immune and autonomic dysfunction. Although the etiology of CFS/ME is not solved yet, there is numerous evidence for an autoantibody mediated dysregulation of the immune and autonomic nervous system. We found elevated ß2 adrenergic receptor (ß2AdR) and M3 acetylcholine receptor antibodies in a subset of CFS/ME patients. As both ß2AdR and M3 acetylcholine receptor are important vasodilators, we would expect their functional disturbance to result in vasoconstriction and hypoxemia. An impaired circulation and oxygen supply could result in many symptoms of ME/CFS. There are consistent reports of vascular dysfunction in ME/CFS. Muscular and cerebral hypoperfusion has been shown in ME/CFS in various studies and correlated with fatigue. Metabolic changes in ME/CFS are also in line with a concept of hypoxia and ischemia. Here we try to develop a unifying working concept for the complex pathomechanism of ME/CFS based on the presence of dysfunctional autoantibodies against ß2AdR and M3 acetylcholine receptor and extrapolate it to the pathophysiology of ME/CFS without an autoimmune pathogenesis.

Individuals with mitochondrial disease often present with psychopathological comorbidity, and mitochondrial dysfunction has been proposed as the underlying pathobiology in various psychiatric disorders. Several studies have suggested that medications used to treat neuropsychiatric disorders could directly influence mitochondrial function. This review provides a comprehensive overview of the effect of these medications on mitochondrial function. We collected preclinical information on six major groups of antidepressants and other neuropsychiatric medications and found that the majority of these medications either positively influenced mitochondrial function or showed mixed effects. Only amitriptyline, escitalopram, and haloperidol were identified as having exclusively adverse effects on mitochondrial function. In the absence of formal clinical trials, and until such trials are completed, the data from preclinical studies reported and discussed here could inform medication prescribing practices for individuals with psychopathology and impaired mitochondrial function in the underlying pathology.

It is widely accepted that the pathophysiology and treatment of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) could be considerably improved. The heterogeneity of ME/CFS and the confusion over its classification have undoubtedly contributed to this, although this would seem a consequence of the complexity of the array of ME/CFS presentations and high levels of diverse comorbidities. This article reviews the biological underpinnings of ME/CFS presentations, including the interacting roles of the gut microbiome/permeability, endogenous opioidergic system, immune cell mitochondria, autonomic nervous system, microRNA-155, viral infection/re-awakening and leptin as well as melatonin and the circadian rhythm. This details not only relevant pathophysiological processes and treatment options, but also highlights future research directions. Due to the complexity of interacting systems in ME/CFS pathophysiology, clarification as to its biological underpinnings is likely to considerably contribute to the understanding and treatment of other complex and poorly managed conditions, including fibromyalgia, depression, migraine, and dementia. The gut and immune cell mitochondria are proposed to be two important hubs that interact with the circadian rhythm in driving ME/CFS pathophysiology.
