Abstract and Figures

Many individuals with gastroesophageal reflux disease (GERD) never visit their general practitioner. Therefore, prospective data about GERD and its natural history in the general population are scarce. The aims of this study were to assess symptoms over time and consultation reasons in an Internet population with GERD. Visitors (18--79 years) to a GERD information website who completed the GerdQ self-assessment questionnaire were invited to participate. Follow-up GerdQ questionnaires were sent after 4, 12 and 24 weeks, and those who had a total GerdQ score >= 8 and responded to at least the baseline and 4-week questionnaires (within 2--7 weeks) were included in the analyses. Outcome in proton pump inhibitor (PPI) and non-PPI users was classified as symptom improvement, symptom persistence/stable symptoms, or symptom relapse according to GerdQ scores. A total of 403 non-PPI users (mean age 48 years, 40% male) and 304 PPI users (mean age 51 years, 41% male) were included. After 24 weeks, symptom improvement was present in 66% of non-PPI users (45/68) and 8% of PPI users (6/73), while persisting symptoms were reported by 24% (16/68) and 89% (65/73) respectively (baseline symptoms did not influence outcome at 24 weeks). Fifty-five percent of PPI users (116/210) and 37% of non-PPI users (76/207) who intended to visit a health care practitioner, performed one or more healthcare visits in the interim. Most frequently reported reason for consultation was persistence of symptoms. GERD symptoms were persistent in the majority of PPI users during our 24-week follow-up, while almost two thirds of non-PPI users reported symptom improvement. Online follow-up of an Internet population with GERD is feasible.

Abstract
Background: Many individuals with gastroesophageal reflux disease (GERD) never visit their general practitioner.
Therefore, prospective data about GERD and its natural history in the general population are scarce. The aims of this
study were to assess symptoms over time and consultation reasons in an Internet population with GERD.
Methods: Visitors (1879 years) to a GERD information website who completed the GerdQ self-assessment
questionnaire were invited to participate. Follow-up GerdQ questionnaires were sent after 4, 12 and 24 weeks, and
those who had a total GerdQ score 8 and responded to at least the baseline and 4-week questionnaires (within
27 weeks) were included in the analyses. Outcome in proton pump inhibitor (PPI) and non-PPI users was classified
as symptom improvement, symptom persistence/stable symptoms, or symptom relapse according to GerdQ scores.
Results: A total of 403 non-PPI users (mean age 48 years, 40% male) and 304 PPI users (mean age 51 years, 41%
male) were included. After 24 weeks, symptom improvement was present in 66% of non-PPI users (45/68) and 8%
of PPI users (6/73), while persisting symptoms were reported by 24% (16/68) and 89% (65/73) respectively (baseline
symptoms did not influence outcome at 24 weeks). Fifty-five percent of PPI users (116/210) and 37% of non-PPI
users (76/207) who intended to visit a healthcare practitioner, performed one or more healthcare visits in the
interim. Most frequently reported reason for consultation was persistence of symptoms.
Conclusions: GERD symptoms were persistent in the majority of PPI users during our 24-week follow-up, while
almost two thirds of non-PPI users reported symptom improvement. Online follow-up of an Internet population
with GERD is feasible.

Background
Gastroesophageal reflux disease (GERD) is a frequent dis-
order with a prevalence in Western countries of around
10-20% [1-3]. As GERD is common in the middle-aged
population, it is associated with decreased work productiv-
ity, including work absenteeism, leading to substantial
indirect healthcare costs [4-7].
Despite the high burden of GERD on available healthcare
resources, data about the natural course of GERD are
scarce [8,9]. As second best, data from placebo groups in-
cluded in randomized therapeutic trials can be evaluated to
develop insight into the natural history of GERD. However,
those studies are mainly p erformed in primary and second-
ary care, where only around 30% of individuals with GERD
symptoms (range: 5 - 56%) ever present with their symp-
toms [10]. Consequently, many individuals that suffer from
GERD are not considered for inclusion in those studies.
Use of the Internet is nowadays widespread and many
individuals use this source for healthca re information
[11-14]. A Dutch website with information about GERD

was launched and website visitors could complete an on-
line survey about symptoms and proton pump inhibitor
(PPI) use. Reasons for visiting a general practitioner or
to refrain from consultation were also asked. This model
provides a unique opportunity to e valuate a population
that has not yet entered the healthcare arena.
The aims of our study are: 1) to prospectively assess
GERD symptoms online; 2) to study healthcare practi-
tioner consultation patterns; and 3) to study underlying
reasons for healthcare visits.
Methods
Study design and participants
The Dutch website www.maagzuur.nl (maag zuur is
Dutch f or ga stric acid ) contains information regarding
GERD symptoms, possible causes, lifestyle advice, diag-
nostic options a nd treatment. In May 2008 the Dutch
translation of t he GerdQ self-assessment questionnaire
(Table 1) was launched on this website and could be
completed by all website visitors. After a p reparatory
period of 6 months, questionnaires completed between
5 December 2008 and 2 April 20 09 could be included in
this study. Follow-up GerdQ questionnaires were sent
to all participants (aged 1879 years) who had a base-
line total GerdQ score 8 and agreed to be contac ted
again. Questionnaires were sent to eligible respondents
after 4, 12 and 24 week s after completion of the baseline
questionnaire. Those who did not complete the first
follow-up sur vey within 7 wee ks were e xcluded to
minimize variance. In case of duplicate GerdQ ques-
tionnaires entries -defined as: identical IP addr ess, birth
year and gender- only the first completed GerdQ ques-
tionnaire was taken into acc ount. Respondent s were
regarded PPI users a s they stated acid suppressive medi-
cation use. The remainde r was classified as non-PPI
users.
The Medical Ethical Committee of the Radboud Uni-
versity Nijmegen assessed the research proposal of this
study and concluded that it could be waived for ethical
review, as we did not gather information about partici-
pants from other sources (e.g. medical records) and data
storage occurred in accordance with Dutch law. For this
reason, we did not obtain written informed consent of
all participants.
GerdQ self-assessment questionnaire
The GerdQ is a short and validated self-assessment
questionnaire that a ssesses presence of GERD and deter-
mines the impact of symptoms on patients daily lives
[15-18]. The GerdQ comprises six questions reflecting
symptoms in the previous 7 days, and has been devel-
oped with questions from the Reflux Disease Question-
naire (RDQ), the Gastrointestinal Symptom Rating Scale
(GSRS), and the Gastrointestinal symptom Scale (GIS),
which are all validated disease-specific questionnaires
[19-21]. The first two questions (1 and 2) are positive
predictors of GERD, and a higher score suggests a higher
symptom frequen cy. Questions 3 and 4 address dyspep-
tic symptoms that lower the probability for GERD, i.e.
they are negative predictors of GERD. The two final
questions (5 and 6) assess the impact of GERD symp-
toms on peoples lives and are also positive predictors of
GERD. The score on every question ranges from 0 to 3
for the four positive predictors of GERD (0 days is a
score of 0, 1 day is 1,23 days is 2,47 days is 3,or
in reversed order for the two negative predictors of
GERD) (Table 1).
Outcomes
Our primary outcome in non -PPI users was sympto m
improvement, which was defined as a GerdQ score < 8
if the respondent scored 8 on the pre vious question-
naire. Stable symptoms were defined as GerdQ score
8 at two subsequent completed questionnaires during
follow-up. Relapse was defined as GerdQ 8, in case
the previous GerdQ score had been < 8.
Our primary outcome in PPI users, symptom im-
provement, was defined as a maximum of one day per
week either heartburn (question 1), regurgitation

(question 2), sleep disturbance (question 5), or over-the-
counter (OTC) acid suppressive medication use (question
6), all during the preceding week. Persistence of GERD
symptoms in PPI users was defined as more than one day
per week with either heartburn (question 1), regurgitation
(question 2), sleep disturbance (question 5), or OTC acid
suppressive medication use (question 6), during the pre-
ceding week. If respondents reported symptoms more
than one day per week for at least 2 subsequent GerdQ
questionnaires, they fulfilled the criteria for persistent
symptoms. If the participant reported an increase in
symptoms from a maximum of one day per week to at
least two times per week, this was defined as symptom
relapse.
Statistical analysis
Data were analyzed with SPSS version 18.0. Baselines
variables for respondents without PPI use and PPI users
were assessed with descrip tive statistics. Percentages of
symptom improvement, stable symptoms, and relapse
were assessed separately for PPI and non-PPI users and
were calculated with chi-squared analysis or Fisher
exact, whenever appropriate. If one of the follow-up
questionnaires was missing, data were compared with
the previous completed questionnaire (e.g. if Survey C
was missing, data of Survey D and B were compared).
Frequencies of heartburn, regurgitation, sleep distur-
bances and OTC acid suppressive medication use during
follow-up were calculated with frequency tables in re-
spondents without PPI use. Mean symptom frequency
within individuals during follow-up was assessed by
paired t-tests in non-PPI users. We analyzed respon-
dents according to (non-) PPI use at baseline.
Respondents were asked at baseline whether they had
intended to visit a healthcare practitioner. During
follow-up we asked whether they had actually visited a
healthcare practitioner. Reasons for consultation were
assessed with closed questions and presented in fre-
quency tables. If respondents performed more than one
healthcare visit during follow-up, only reasons for the
first visit were taken into account. In respondents that
did not visit a healthcare provider during follow-up, rea-
sons that were reported in the last completed question-
naire were included and depicted in frequency tables.
Associations between outcome at 24 weeks and GerdQ
score at baseline and type of symptom at baseline were
analyzed with chi-squared analyses. We also analyzed
the percentage of responde nts that started or stopped
their PPI with descriptive statistics. For this analysis, we
only took the first medication switch into account. A per
protocol analysis was performed, including only those
respondents who did not change their use or non-PPI
use during the 24-week follow-up. A P-value of < 0.05
was considered to be statistically significant.
Results
A total of 707 respondents met the predefined in- and
exclusion criteria and completed the GerdQ between 5
December 2008 and 2 April 2009 (Figure 1). Forty-three
percent of respondents (N = 304) reported PPI use, the
remainder were classified as non-PPI users. Mean age of
individuals without PPI use was 48 years (SD 13) and 40%
was male. Mean age of PPI users was 51 years (SD 12) and
41% was male.
In the non-PPI using group, 68 respondents completed
follow-up, of which symptom improvement was present in
45 respondents (66%) and relapse in 7 respondents (10%,
Figure 2). Symptoms were persistent in the remaining
16 respondents (24%). In addition, we assessed 4 indi-
vidual GerdQ questions during follow-up (Table 2). After
24 weeks, heartburn or regurgitation for a maximum of

one day per week was reported by 44% and 81% of respon-
dents without PPI use, respectively. Mean symptom fre-
quencies of heartburn and regurgitation in non-PPI users
significantly declined within individuals during follow-up
from 2.21 at baseline to 1.43 at 24 weeks and from 1.20 to
0.77, respectively (both p < 0.01). Mean symptom frequen-
cies of sleep disturbance and OTC use in non-PPI users
declined from 1.52 to 1.20 (P = 0.30) and from 1.58 to 1.23
(p = 0.67), respectively.
In PPI users who completed follow-up (n = 73),
65 (89%) reported persistence of symptoms , 6 (8%)
reported symptom improvement and 2 (3%) relapse of
symptoms (Figure 3). Neither individual symptoms nor
GerdQ scores at baseline were associated with symptom
improvement at 24 week s in respondents that did and
did not use PPIs.
During follow-up, 22% started (n = 89/403) and 17%
stopped PPI use (n = 53/304). If we excluded these indi-
viduals from our analyses, we found that 69% of individ-
uals without PPI use reported symptom improvement
(33/48) at 24 weeks in this per protocol analysis. In PPI
users, 2 participants (2/61; 3%) reported symptom
improvement, and the majority (58/61; 95%) reported
persistent symptoms.

Healthcare consultation patterns
At baseline, 207 respondents withou t PPI use reported
the intention to visit a healthcare provider. A total of 63
(30%) and 76 (37%) res pondents who were planning to
visit a physician had indeed visited a healthcare practi-
tioner after 4 weeks and 24 weeks, respectively. A total
of 210 PPI users intended this visit, and 94 respondents
(45%) had visited a physician after 4 weeks. At the end
of follow-up, 116 (55%) PPI users with the intent ion to
visit a physician had actually done so.
The most reported reason to consult a healthcare pro-
vider was persistence of GERD symptoms, which was
mentioned by 68% of non-PPI users and 73% of PPI users
(Table 3). For non-PPI users, worries (44%) and impact on
daily life (41%) were also frequently mentioned. In PPI
users, impact on daily life (52%), and increased GERD
symptom severity (40%) were frequently described rea-
sons. The most reported reason to refrain from consult-
ation was insufficient GERD symptom severity in non-PPI
users (44%), and in PPI users (21%, Table 4).
Discussion
We found that 66% of the individuals without PPI use
reported symptom improvement at the end of follow-up
at 24 weeks. In contrast, only 8% of PPI users reported
symptom improvement at the end of follow-up and 89%
of PPI users reported persistent symptoms.
Limited data are available about long-term effectiveness
of PPI therapy in GERD. Short-term studies conclude that
17-45% of patients with GERD do not respond adequately
to PPI therapy [22]. Symptom severity was comparable or
had improved in the majority of patients after five years in
the proGERD study [23]. However, patients included in
this proGERD study were recruited from secondary care,
whilst our population was not selected by physicians and
we did not apply strict inclusion and exclusion criteria.
Our population probably also contains respondents with
functional upper gastrointestinal symptoms who are less
likely to respond to PPI therapy than those with GERD.
These factors, in addition to selection bias, could have
contributed to the very high rate of persistence of symp-
toms in PPI users.
As we also focused on a different GERD population,
namely Internet users with GERD symptoms without PPI
use, we are not able to directly compare our results with
others. As second best, we can use placebo responses in

clinical trials. A meta-analysis in patients with GERD con-
cluded that the average placebo response was 19% [24].
Follow-up of included studies was short with a maximum
of 12 weeks. We found a higher percentage of symptom
improvement at 4 and 12 weeks. This can be explained by
the inclusion of patients with more severe symptoms in
clinical trials and by the definition we used for symptom
improvement.
Because many individuals with GERD symptoms re-
frain from consultations, it is interesting to assess under-
lying reasons for the decision to visit or not. In a survey
among GERD patients in primary care, 52% mentioned
that symptoms too uncomfortable to bear was the
main reason for consultation [25]. The most frequently
reported reason for consultation in our study was per-
sistence of GERD symptoms (68% in non-PPI users, 73%
in PPI users). Worries about their symptoms were
reported by 44%% of non-PPI users and 37% of PPI
users. Fear is frequently thought to be one of the most
important reasons for seeking help, but we were not able
to confirm this assumptio n.
We used the 6-item GerdQ self-assessment question-
naire for follow-up of GERD. The GerdQ appears to be
a very promising tool to assess GERD symptoms in a
structured, easy way and it is increasingly being used in
clinical practice. A re cently published study compared a
treatment-algorithm based on the GerdQ with common
practice of upper endoscopy and if indicated, pH metry
in patients with GERD symptoms without any alarm
signs. Use of the GerdQ approach was associated with a
decrease in healthcare exp enses, but had a comparable
efficacy [16].
We believe that our data adds to the total, diverse
population of individuals with GERD, of which only a
minority visits healthcare practitioners. We were able to
demonstrate how GERD symptoms evolve on and off
PPI treatment. However, including respondents online is
associated with limitations, most importantly selection
bias. We faced a high dropout rate, probably related to
the noncommittal attitude of an online questionnaire
and the fact that we asked respondents to complete a
total of 4 questionnaires during follow-up. We also do
not have additional information about the medical his-
tory, comorbidity and reports of any additional investi-
gations, such as upper endoscopy. We therefore cannot
exclude that we included individuals with other diagno-
ses than GERD, or with concomitant diseases in addition
to GERD. Another limitation is that we did not question
the type and dose of PPI and the duration of use.
Implications
Our study has implications for clinical practice. We
have shown that it is feasible to use the GerdQ self-
assessment questionnaire in PPI users to assess response
to acid suppressive therapy over time. We observed that
two thirds of non-PPI users had symptom improvement
after 24 weeks. This supports the guidelines wherein first
treatment step is lifestyle advice [26,27]. Effectiveness of
lifestyle interventions has never been system atically
studied, but in specific individuals these measures ap-
pear to be successful. In addition, our respondents
reported confidence in lifestyle interventions (Table 4).
When symptoms persist after lifestyle interventions,
PPIs can be prescribed.
Our unique approach of online incorporation and
follow-up of individuals with GERD demonstrates that
the Internet can be used to trace individuals with spe-
cific symptoms and the follow-up via the Internet can be
used as complementary method to the traditional routes.
The communication in our study was one directional,
but we will foresee an increase in onlin e health plat-
forms with direct patient-physician communication by
e-mail, blog, or message services.
Conclusions
We found in our 24-week follow-up study via the Inter-
net, that more than half of the respondents without PPI
use reported symp tom improvement. However, more
than 90% of PPI users reported persistence of symptoms.
The most frequently mentioned reason for healthcare
visits was persistence of symptoms. Based on our results,
we support the use of the GerdQ to assess GERD symp-
toms and we agree with current guidelines that PPI pre-
scription is not the first treatment step when patients
present with symptoms suggestive of GERD. We have
shown that online follow-up of an Internet population
with GERD is feasible.

Aim: The purpose of this study was to determine the prevalence and risk factors of GERD in Indonesian population. Methods: An online survey was conducted using Survey Monkey®, from August 2013 to June 2015. People who completed all questions were recruited as research subjects. The diagnosis of GERD and its impact on daily life were determined using GERD Questionnaire (GerdQ) score, and all possible factors were analyzed to determine their association with GERD. Results: 2045 subjects completed the survey; their mean was age 31.4±8.8 years and 52.8% were female. The prevalence of GERD was 57.6%; 21.9% reported a low impact and 35.7% a high impact on their daily life. GERD was significantly associated with age >50 years old (p = 0.002; odds ratio [OR] 3.179), male (p = 0.009; OR 1.268), low to middle educational level (p = 0.033; OR 1.238), and body mass index (BMI) >30 kg/m²(p = 0.015; OR 1.509). Conclusions: The prevalence of GERD in Indonesia was 57.6%. Age >50 years old, male, low to middle educational level, and obesity were risk factors for GERD.

Introducción: Evidencia actual ha comprobado la relación directa en esófago de Barrett, de hernia hiatal y trastorno motor esofágico; de este, significativamente el Síndrome de motilidad inefectiva y peristalsis fragmentada. Esto plantea al trastornos motor esofágico como factor de riesgo independiente en pacientes con Enfermedad por Reflujo Gastroesofágico para el desarrollo de esófago de Barrett. Objetivo: Determinar la relación entre esófago de Barrett y trastornos motores esofágicos, en pacientes del Hospital Juárez de México. Material y métodos: Estudio observacional-descriptivo, transversal, ambispectivo, de cohortes. Se incluirán todos los pacientes con diagnóstico histológico de Barrett (grupo de estudio), reportado en enero de 2015 a mayo de 2019. Grupo control: pacientes con esofagitis grado C; clasificaciones de Praga y de los Ángeles respectivamente. Relación de grupos: 1:1. Manometría esofágica de alta resolución y aplicación de los cuestionarios GERD-Q, y el diseñado para el estudio, a ambos. Estadística descriptica para variables demográficas; no paramétrica con chi cuadrada, para muestras independientes nominales. Resultados: En el tiempo del estudio se corroboraron 76 casos de esófago de Barrett, con una mayor prevalencia en la sexta década de la vida y en el género masculino, con 67.1% de los casos. El 93.43% de la metaplasia intestinal correspondiente fue de tipo incompleta, el 78.94% de los casos no presentó displasia. En cuanto al grupo de displasia, el 43.75% correspondió a displasia de bajo grado, la cual fue más prevalente en hombres, con 85.71%; la displasia indeterminada se presentó en 43.75% de los casos, con mayoría igualmente de casos en el género masculino, 71.42%; en cuanto a la displasia de alto grado, se presentó en 12.5% de los casos y con distribución igual en ambos géneros, 50%. La correlación endoscópico-patológica en nuestro estudio fue del 60.854%, con 38.26% de falsos positivos, 7.478 de falsos negativos y prevalencia global de esófago de Barrett del 0.657% en nuestra población. Resultados prospectivos parciales: el trastorno motor esofágico más prevalente fue motilidad esofágica inefectiva con el 66.6% de los participantes, comparado con 16.6% en pacientes con esofagitis C de los Angeles. Conclusiones: Este estudio demuestra la baja prevalencia del esófago de Barrett en nuestra población, su mayor frecuencia en el género masculino y en la sexta década de la vida. La correlación endoscópico-patológica es un área de oportunidad, así como el porcentaje de falsos positivos y negativos. Preliminarmente, se puede esperar que la motilidad esofágica inefectiva sea el trastorno motor esofágico más relacionado a esófago de Barrett.

Purpose: Patients with gastroesophageal reflux disease without esophagitis show varying responses to proton pump inhibitors (PPIs). The aim of this study was to objectively evaluate the effect of a new PPI, ilaprazole, on patients with heartburn but without reflux esophagitis. Materials and methods: This prospective study was performed on 20 patients with heartburn but without reflux esophagitis. All patients underwent upper endoscopy and 24-hr combined multichannel intraluminal impedance and pH esophageal monitoring (MII-pH). They were then treated with ilaprazole (20 mg) once daily for 4 weeks. The GerdQ questionnaire, histologic findings, and inflammatory biomarkers were used for assessment before and after ilaprazole. Results: Among the 20 patients, 13 (65%) showed GerdQ score ≥8. Based on MII-pH results, patients were classified as true nonerosive reflux disease (n=2), hypersensitive esophagus (n=10), and functional heartburn (n=8). After treatment, patients showed a statistically significant improvement in GerdQ score (p<0.001). Among histopathologic findings, basal cell hyperplasia, papillary elongation, and infiltration of intraepithelial T lymphocytes improved significantly (p=0.008, p=0.021, and p=0.008; respectively). Expression of TNF-α, IL-8, TRPV1, and MCP-1 decreased marginally after treatment (p=0.049, p=0.046, p=0.045, and p=0.042; respectively). Conclusion: Daily ilaprazole (20 mg) is efficacious in improving symptom scores, histopathologic findings, and inflammatory biomarkers in patients with heartburn but no reflux esophagitis.
Chapter
Gastroesophageal reflux is a very common presenting symptom that should be worked up carefully as many patients respond to medical therapy. There is a risk of progressing to esophageal cancer in the setting of untreated reflux. In this chapter, the evaluation and management of patients with reflux are reviewed. Surgical approaches to treat the disease are outlined.

Chest pain experienced by patients with coronary artery disease can be partly due to gastroesophageal reflux-induced chest pain (GERP). Empirical proton pump inhibitor (PPI) therapy has been recommended as an initial clinical approach for treating GERP. However, PPI use may lead to some health problems. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) may represent a noninvasive and cost-effective approach for avoiding PPI misuse and for identifying the appropriate patients for the PPI trial test. The aim of this pilot study was to prospectively evaluate the association between GerdQ scores and PPI response in patients with coronary artery disease (CAD) and GERP to determine whether the GerdQ predicts the PPI response in patients with CAD and GERP and to further validate the clinical application value of the GerdQ. A total of 154 consecutive patients with potential GERP were recruited to complete a GerdQ with subsequent PPI therapy. Based on the PPI trial result, patients were divided into a PPI-positive response group and a PPI-negative response group. The difference in the GerdQ scores between the two groups was assessed. The receiver operating characteristic (ROC) curve of GerdQ score was drawn according to the PPI response as the gold standard. The ability of GerdQ to predict the PPI response was assessed. A total of 96 patients completed the entire study; 62 patients (64.6%) were assigned to the PPI-positive response group, and 34 patients (35.4%) to the PPI-negative response group. The GerdQ score of the PPI-positive response group (8.11 ± 3.315) was significantly higher than that of the PPI-negative response group (4.41 ± 2.743), and the difference was statistically significant (t = 5.863, P = 0.000). The ROC curve was drawn according to a PPI response assessment result with a score above 2 as the gold standard. The area under curve was 0.806. When the critical value of GerdQ score was 7.5, Youden index was up to 0.514, the diagnostic sensitivity was 0.661, and the diagnostic specificity was 0.853. A GerdQ score greater than 7.5 better predicts the response to the PPI trial therapy. There is a strong association between the GerdQ score and the response to PPI therapy. Higher GerdQ scores were predictive of a positive PPI response in CAD patients with GERP. The GerdQ may be a reasonable screening tool for GERP in patients with CAD who are prepared to accept PPI therapy. © 2015 International Society for Diseases of the Esophagus.

There are problems with the definition, assessment, and measurement of gastroesophageal reflux disease (GERD). The Reflux Disease Questionnaire and the GERD questionnaire are patient-reported outcome (PRO) measures for use in a primary care setting, which are easy to use and are validated. There is no widely accepted definition of a proton pump inhibitor test and performance of the test in the clinical setting is not standardized. The use of the PRO measures in primary care with predetermined cutoff values may help to reduce the cost of diagnosing GERD and increasing rates of response for evaluated patients to acid suppression.

Background Persons with gastroesophageal reflux disease (GERD) frequently search online for information about causes and treatment options. The GerdQ self-assessment questionnaire can be used for diagnosis of GERD and follow-up of symptoms. Objectives To assess whether it is feasible (1) to study the prevalence and impact of GERD in persons visiting a GERD information website, and (2) to identify partial responsiveness to proton pump inhibitor (PPI) therapy using the GerdQ. Methods All visitors (aged 18–79 years) to a GERD information website between November 2008 and May 2011 were invited to complete the GerdQ online. The GerdQ questionnaire consists of 6 questions (score per question: 0–3). In respondents who did not use PPIs, we used the questionnaire to identify those with GERD (total score ≥8) and assess the influence of these symptoms on their daily life, divided into low (total score

Background Gastrointestinal reflux disease (GERD) is a common disorder that negatively impacts health-related quality of life (HRQL) and work productivity. Many patients have only a partial response to proton pump inhibitor (PPI) therapy and continue to experience GERD symptoms despite optimized treatment. This observational study aimed to provide information on symptoms, HRQL, resource usage, costs and treatment pathways associated with partial response to PPI therapy in French patients with GERD. Methods Patients with partial response to PPI therapy, defined as persistent GERD symptoms ≥3 days/week despite optimized treatment with a PPI, were recruited for this 12-month observational study. GERD symptoms, HRQL, work productivity and resource use were assessed by patient surveys. Costs were calculated based on lost work productivity and resource use. Results The patient population (n=262; mean age, 54 years; 40% men) carried a significant symptom burden, with 98% of patients having moderate-to-severe GERD symptoms and 65% of patients experiencing daily symptoms at baseline. HRQL and work productivity were significantly impaired, with a greater degree of impairment in patients with higher symptom burden. The mean total cost per patient over the 12-month follow-up period was €5237, of which €4674 (89%) was due to lost work productivity. Conclusions Partial response to PPI therapy for GERD is associated with a high symptom burden, significant impairment of HRQL and work productivity, and substantial GERD-related costs.

The evolution of gastro-oesophageal reflux disease (GERD) under current management options remains uncertain. To examine whether, depending on the initial presentation, non-erosive (NERD) and erosive reflux disease (ERD) without Barrett's oesophagus will progress to more severe disease under current routine care following the resolution of the initial condition. Patients with the primary symptom of heartburn were included at baseline, and stratified into non-erosive (NERD) and erosive reflux disease (ERD), LA grades A-D (Los Angeles classification). After a 2- to 8-week course with esomeprazole therapy to achieve endoscopic healing in ERD and symptom relief in NERD, patients were treated routinely at the discretion of their physician. We report oesophagitis status and the presence of endoscopic and confirmed Barrett's oesophagus after 5 years. A total of 6215 patients were enrolled in the study of whom 2721 patients completed the 5-year follow-up. Progression, regression and stability of GERD severity were followed from baseline to 5 years. Only a few patients with NERD and mild/moderate ERD progressed to severe forms of ERD and even Barrett's oesophagus. Most patients remained stable or showed improvement in their oesophagitis; 5.9% of the NERD patients, 12.1% of LA grade A/B patients and 19.7% of LA grade C/D patients in whom no Barrett's oesophagus was recorded at baseline progressed to endoscopic or confirmed Barrett's oesophagus at 5 years. Most GERD patients remain stable or improve over a 5-year observation period under current routine clinical care.

Background Most households in the United Kingdom have Internet access, and health-related Internet use is increasing. The National Health Service (NHS) Direct website is the major UK provider of online health information. Objective Our objective was to identify the characteristics and motivations of online health information seekers accessing the NHS Direct website, and to examine the benefits and challenges of the health Internet. Methods We undertook an online questionnaire survey, offered to users of the NHS Direct website. A subsample of survey respondents participated in in-depth, semistructured, qualitative interviews by telephone or instant messaging/email. Questionnaire results were analyzed using chi-square statistics. Thematic coding with constant comparison was used for interview transcript analysis. ResultsIn total 792 respondents completed some or all of the survey: 71.2% (534/750 with data available) were aged under 45 years, 67.4% (511/758) were female, and 37.7% (286/759) had university-level qualifications. They sought information for themselves (545/781, 69.8%), someone else (172/781, 22.0%), or both (64/781, 8.2%). Women were more likely than men to seek help for someone else or both themselves and someone else (168/509 vs 61/242, χ22 = 6.35, P = .04). Prior consultation with a health professional was reported by 44.9% (346/770), although this was less common in younger age groups (
Article
The diagnosis of gastro-oesophageal reflux disease (GERD) remains a challenge as both invasive methods and symptom-based strategies have limitations. The symptom-based management of GERD in primary care may be further optimised with the use of a questionnaire. To assess the diagnostic validity of the GerdQ questionnaire in patients with symptoms suggestive of GERD. Patients with symptoms suggestive of GERD without alarm features, underwent upper endoscopy, and if normal, pH-metry. Patients were followed for 4 weeks and GerdQ was completed blinded to the investigator at both visits. Reflux oesophagitis or pathological acid exposure was used as diagnostic references for GERD. The diagnostic accuracy for GERD on symptom response to proton pump inhibitor (PPI) was assessed. Among the 169 patients, a GerdQ cutoff ≥9 gave the best balance with regard to sensitivity, 66% (95% CI: 58–74), and specificity, 64% (95% CI: 41–83), for GERD. The high prevalence of reflux oesophagitis (81%) resulted in a high proportion of true positives, but at the same time a high proportion of false-negatives. Consequently, GerdQ had a high positive predictive value, 92% (95% CI: 86–97), but a low negative predictive value, 22% (95% CI: 13–34), for GERD. Symptom resolution on PPI therapy had high sensitivity, 76% (95% CI: 66–84), but low specificity, 33% (95% CI: 17–53), for GERD. GerdQ is a useful complementary tool for the diagnosis of gastro-oesophageal reflux disease in primary care. The implementation of GerdQ could reduce the need for upper endoscopy and improve resource utilisation. Symptom resolution on proton pump inhibitor did not predict gastro-oesophageal reflux disease.

The diagnosis of gastro-oesophageal reflux disease (GERD) remains challenging. An algorithm, facilitated by a questionnaire, may provide a more structured and cost-effective care of patients. To compare symptom control achieved with empirical therapy for GERD, in an algorithm based on the GerdQ (new structured pathway, NSP), with that of current care after endoscopy (ordinary clinical pathway, OCP). Patients with symptoms of GERD, but without alarm features, were randomised in an open, parallel-group study and followed for 4-8 weeks. In the NSP, GerdQ score was used as a basis for both diagnosis and a treatment algorithm. Patients with high likelihood of GERD were treated empirically with a PPI whereas patients with low likelihood of GERD received therapy chosen by the clinician. In the OCP, diagnosis and treatment were based on endoscopy or pH-metry findings. The statistical hypothesis was non-inferiority of NSP to OCP. A total of 147 patients (86.5%) in the NSP and 133 patients (80.1%) in the OCP arm were responders. Overall, NSP was non-inferior to OCP, but not superior (P = 0.14). Patients with high likelihood of GERD had significantly better symptom relief in the NSP (P = 0.03), whereas those with low likelihood of GERD showed a numerical difference in favour of an endoscopy-based approach (OCP). NSP saved 146 € per patient. A symptom-based approach using GerdQ reduced health care costs without loss in efficacy. Patients with high likelihood GERD benefited from empirical treatment. An algorithm based on GerdQ may provide physicians with a tool for a more structured care of patients (ClinicalTrials.gov NCT00842387).

Persistent gastro-oesophageal reflux disease (GERD) symptoms can occur despite proton pump inhibitor (PPI) therapy. To assess the prevalence and potential determinants of persistent GERD symptoms in primary care and community-based studies. Studies were identified by systematic PubMed and Embase searches; pooled prevalence data are shown as sample-size weighted means and 95% confidence intervals. Nineteen studies in individuals with GERD taking a PPI were included. In interventional, nonrandomized primary care trials, the prevalence of persistent troublesome heartburn and regurgitation was 17% (6-28%) and 28% (26-30%) respectively; in randomized trials, it was 32% (25-39%) and 28% (26-30%), respectively. In observational primary care and community-based studies, 45% (30-60%) of participants reported persistent GERD symptoms. Overall, persistent GERD symptoms despite PPI treatment were more likely in studies with a higher proportion of female participants [>60% vs. <50%, risk ratio (RR): 3.66; P < 0.001], but less likely in studies from Europe than in those from the USA (RR: 0.71; P < 0.001), and were associated with decreased psychological and physical well-being. Persistent GERD symptoms despite PPI treatment are common in the primary care and community setting. Alternative approaches to management are required.
