e AIDS pandemic has made diseases such as tuberculosis, CMV disease, and other opportunistic infections more prevalent;
these diseases may even be found to be associated among themselves, and the natural history of each disease may present in an
unusual manner. We report the case of a 41-year-old man with HIV (CD4 of 144 cells/dL) and HCV with hematochezia due to
tuberculosis in the ileocecal valve and descending colon and CMV tissue invasive disease in the esophagus and descending colon.
Coinfection among tuberculosis and cytomegalovirus in the gastrointestinal tract was described only once in a patient with
a recent diagnosis of HIV that aected the distal ileum and ascending colon. We will discuss the peculiarities of the case and the
behavior of the immune system in the face of simultaneous opportunistic infections. is is a challenging scenario that has scarce
publications and is of great clinical importance.
1. Introduction
e pandemic human immunodeciency virus (HIV) has
dramatically changed the opportunistic infections epide-
miology, such as for tuberculosis and cytomegalovirus
(CMV) disease. Both have become more prevalent and could
be found in association in the same patient, possibly with an
unusual natural history [1–4]. e neglect and poor adhesion
to antiretroviral therapy (ART), the therapeutic failure, and
the lack of access to this therapy made possible that this type
of manifestation continued to occur in the same manner it
used to occur in the pre-ART era [1–4].
e highest prevalence of tuberculosis cases is concen-
trated in the south of Asia and Africa [5]. However, in Brazil,
mostly in Rio de Janeiro, the Brazilian province with highest
prevalence, the disease’s incidence is approximately 70.57 in
100,000 inhabitants in 2012 [6]. e low socioeconomic
condition, undiagnosed sick people in circulation, and the
poor adherence to treatment result in an increase of new
cases, which are often associated with HIV immunode-
pression [7]. It is estimated that 95% of the cases in the world
occur in underdeveloped or emerging countries with lower
life quality, which shows the relationship between this
disease and socioeconomic issues [8]. By 2015, it was esti-
mated that at least 11 million people were coinfected with
HIV and Mycobacterium tuberculosis in the world, and from
individuals diagnosed with tuberculosis in 2007, approxi-
mately 11% were HIV positive. Tuberculosis in the gas-
trointestinal tract, of interest to our case, is a less common
presentation compared to the classical pulmonary form,
which occurs mainly in immunosuppressed individuals [9].
Another infectious agent of interest to our study, which
became more prevalent with the spread of AIDS, is cyto-
megalovirus (CMV), a virus from the herpesvirus family.

Beyond the congenital, the perinatal, and the mononucleosis-
like manifestations, cytomegalovirus is also a typically op-
portunistic infection. In South America, Africa, and Asia,
where the prevalence of CMV infection is higher, primary
infection usually occurs during childhood, following a period
of clinical latency [10]. Reactivation occurs in an immuno-
suppressive situation. CMV promotes vasculitis and in-
ammatory lesions in several tissues, such as the retina, lung,
and gastrointestinal tract, especially in HIV patients with CD4
T cells <50 cells/dL [11, 12].
A relevant topic is that the simultaneous manifestations
of opportunistic diseases in the context of AIDS are re-
current, reaching up to 33% of the patients who have some
opportunistic presentation [13]. is fact creates a chal-
lenging condition due to the dicult diagnosis because
physicians are trained to diagnose parsimoniously, and
multiple infections of the same anatomical site can simulate
a single infection due to the similarity of the symptoms
among them [14, 15]. Regarding the possible synergisms in
the coinfection by dierent agents, bidirectional interaction
of HIV and tuberculosis coinfection has already been de-
scribed, such that one contributes to the aggravation of the
other. HIV increases the risk of reinfection and reactivation
of M. tuberculosis by reducing the 1 response prole of the
immune system. At the same time, tuberculosis in the pa-
tient with HIV promotes a reduction of CD4+ T cells and
accelerates HIV replication through the production of tumor
necrosis factor-alpha (TNF-alpha) and monocyte chemo-
tactic protein 1 (MCP1) [14, 16].
We will discuss the correlation and immunological eects
of HIV, M. tuberculosis, and CMV coinfection by reporting
a case of tuberculosis in the ileocecal valve and descending
colon and cytomegalovirus in the esophagus and descending
colon, as well as with chronic hepatitis C virus (HCV) in-
fection. e understanding of the behavior of the immune
system in the face of simultaneous infections is a challenging
scenario with scarce publications, especially about humoral
and cellular immune response aspects.
2. Case Report
A 41-year-old man, a native from Rio de Janeiro and an HIV
and HCV carrier, without criteria for the treatment for HCV
(detectable viral load, without cirrhosis and with normal
transaminase levels), who had abandoned ART, had attended
the Gare´
eand Guinle University Hospital’s immunology
clinic complaining about continuous epigastric burning pain
without irradiation and with diuse abdominal pain that was
mild and continuous, which had started approximately two
months prior to admission. He also complained about intense
hematochezia that had started three weeks before, with in-
tense ow and with “pure blood” appearance without clots.
He presented with daily hyperthermia since the abdominal
symptoms had started with intermittent high fever and an
over 10% body weight loss in the same period. e physical
examination revealed oral candidiasis, bleached mucous
membranes, and cachexia. At the admission time, the HIV
viral load was recorded at 905,569 copies per ml, and the
TCD4 lymphocyte count was 144 cells/dL. Prophylactic
sulfamethoxazole-trimethoprim 400/80 mg 2 IV ampoules
once daily and uconazole 200 mg IV once daily for treatment
of the oral candidiasis were prescribed. e patient’s con-
dition evolved without major occurrences or complaints,
presented with high fever, above 38°C almost every day. Blood
counts revealed thrombocytopenia, neutrophilia, lympho-
penia, anemia, microcytosis, and anisocytosis (Table 1). e
medical team requested upper digestive endoscopy (Figure 1)
and colonoscopy (Figure 2), which veried the presence of
ulcer with irregular and raised edges, brinonecrotic base,
measuring approximately 3 cm in the middle third of the
esophagus and 30 cm from the incisors and the mild antrum
gastritis, and swollen, irregular, and brinous ulcers in the
ileocecal valve, descending colon, and all other segments. e
lesions were similar to those found in the esophagus, which
could suggest the same etiology. It was suggested by the
internal medicine team that the diagnosis could be a coin-
fection (tuberculosis, cytomegalovirus, and herpes simplex
virus disease). e diagnosis of tuberculosis and cytomega-
lovirus coinfection of the gastrointestinal tract was conrmed
by the histopathological report (ZiehlNeelsen staining of
acid-fast bacilli, CMV intracytoplasmic inclusions in Giemsa
staining, and immunohistochemical study with positive la-
beling for CMV in cells with clear halos), and some time later,
culture with the growth of M. tuberculosis (Figure 3).
Treatment was started with an RIPE scheme (rifampicin
+ isoniazid + pyrazinamide + ethambutol) 4 tablets daily and
ganciclovir 350 mg IV for 21 days with a weight gain of 4 kg
and clinical and laboratory improvement. He was discharged
from the hospital with ART lamivudine, tenofovir, and efa-
virenz (TDF + 3TC+ EFV) one tablet per day and was re-
ferred to a clinical follow-up for tuberculosis and HIV/HCV
coinfection monitoring. At the end of the treatment for tu-
berculosis and 6 months after ART was restarted, the patient’s
viral load was <40 copies/dL and the CD4+ T-cell count was
356 cells/dL, asymptomatic.
3. Discussion
In the present case, an AIDS patient with ART abandon,
coinfected with HCV, tuberculosis, and simultaneous cy-
tomegalovirus in the gastrointestinal tract, was reported. In

the laboratory tests, microcytic anemia with anisocytosis
suggested iron deciency secondary to nutritional causes
and chronic gastrointestinal bleeding. AIDS-typical labo-
ratory ndings were lymphopenia with neutrophilia and
thrombocytopenia, which may also be related to chronic
HCV infection [17].
CMV retinitis is the most frequent presentation of
cytomegalovirus, accounting for up to two-thirds of the
manifestations in target organs [18]. However, it is not
uncommon to nd extraocular manifestations in immu-
nosuppressed patients, such as the pulmonary, neurological,
and intestinal forms; the last one represents approximately 5
to 10% of the total [11, 18]. In gastrointestinal cytomega-
lovirus, colitis is the most common presentation, followed
by esophagitis [19], occurring exactly at these sites in the
case described. In tuberculosis cases, the most frequent
form is pulmonary, and the extrapulmonary forms, less
common and related to immunosuppression, represent only
14.4% of all diagnoses [1, 7]. From all the extrapulmonary
forms, the intestinal is the sixth in frequency, and ap-
proximately 2530% of the cases have the concomitant
pulmonary form, which was not observed in our patient.
e esophageal involvement here presented is rare and of
lesser severity, representing only 0.15% of all deaths due to
tuberculosis [9].
e tuberculosis and cytomegalovirus coinfection, al-
though rarely described, has been already reported in other
tissues [4, 20, 21]. In the gastrointestinal tract, it was de-
scribed only once, in a patient with a recent diagnosis of
HIV, aecting the distal ileum and ascending colon, pre-
senting shock due to massive intestinal hemorrhage. As such
complications are rare in intestinal tuberculosis, the hy-
pothesis was raised that this complication could have been
caused by a possible synergism between tuberculosis and
cytomegalovirus, which was conrmed by histopathology
[3]. However, the esophagus involvement by these two
diseases together, as in the case here presented, has not been
described yet.
e negative eect that HIV infection plays on the
TH1 immune response prole, which is the main eective
response against mycobacteria [16] and essential for
maintaining CMV latency [4], is a determining immu-
nological factor for this type of association [16]. Addi-
tionally, the cytopathic lesion that HIV itself produces in
the intestinal epithelium is already a facilitator to new
infections in this site [22]. is process occurs by the virus
direct toxic action, by the lymphocytes inammatory
inltrate in the lamina propria, and by the gastrointestinal
immune system activation, with increased TNF-alpha
production, a cytokine related to enterocytes apoptosis

[23]. On the other hand, what we have observed is that the
opportunistic infections themselves also contribute to the
HIV progression. As HIV is predisposed to infect CD4+
T cells, any local infection that causes the recruitment of
such cells will lead to more infection targets for the virus
and its consequent replication [23]. Tuberculosis infec-
tion also promotes the abrupt decline in CD4+ T cells in
HIV carriers, more specically the 1 cells. Additionally,
increased viral replication has been demonstrated in those
macrophages located in mycobacterial-infected sites, due
to the increase of NF-kappa beta and TNF-alpha [15, 16].
Moreover, the relative risk of death and development of
other opportunistic infections is greater in patients with
HIV-TB coinfection [24].
Tuberculosis has also been demonstrated to inuence
CMV reactivation by inducing Mip-1beta production by
CMV-specic response CD4 cells. us, tuberculosis in-
fection also becomes a risk factor for CMV reactivation by
accelerating the immunodepression progression by HIV. In
addition, tuberculosis also stimulates the production of
inammatory cytokines that aid CMV reactivation [4].
As tuberculosis is an infection that manifests itself in-
dependently of CD4 T-cell levels [14], it is more likely to be
the rst opportunistic infection to occur and thus predispose
the organism to others that occur with a lower CD4 count,
such as CMV. However, as in the case described, the pre-
sentation of tuberculosis was intestinal, which depends on
a more pronounced immunosuppression degree, and further
without concomitant pulmonary infection, we cannot rule
out the hypothesis that CMV would have appeared initially
and, by the local replication of HIV itself, it would have
caused tuberculosis reactivation at the same site.
Additionally, CMV actively infects monocytes, which are
essential cells in the production of inammatory cytokines
that modulate the immune response to tuberculosis and HIV
infection [11, 15]. It is therefore likely that CMV infection
takes part in causing other infections or the reactivation of
opportunistic agents due to inammatory cytokine pro-
duction, similar to what has already been described in tu-
berculosis and HIV. CMV also promotes a change in natural
killer (NK) cell receptor patterns in the body with the
predominance of the inhibitory-type NK cell receptors
(NKG2C) compared to the activation type (NKG2A) [25],
impairing the body’s responses to other agents. e
mechanisms described may partially explain the multidi-
rectional interaction between these infections, so that only
one of them itself is enough to cause the emergence of the
others.
In the other case described in the literature [3], no clinical
improvements were identied until CMV infection was
identied and treated, which necessitates the skilled diagnosis
of coinfections. Table 2 compares clinical and epidemiological
aspects between tuberculosis and CMV infection in the
gastrointestinal tract, demonstrating their main dierences
[9, 16, 26, 27]. e lesions’ appearances, found in our case’s
colonoscopy, were suggestive of ulcerative-type intestinal

erosions.

tuberculosis, but the signicant ulceration extension that was
found led to the suspicion of a coinfection responsible for
magnifying the damage to the epithelium.
It should be noted that CMV has been reported in AIDS
patients in coinfection with other diseases, such as pneu-
mocystosis and Mycobacterium avium infection in the
pulmonary tract [20, 21], and it has also been proposed as
a facilitating agent for Kaposi’s sarcoma [28]. Likewise,
tuberculosis has been reported in coinfection with other
opportunistic diseases, mainly in the pulmonary tract, such
as pneumocystosis, histoplasmosis, M. avium, and para-
coccidioidomycosis [2, 20, 21, 29, 30]. Possibly, the fre-
quency of these coinfections mentioned above is greater than
we imagine, especially in cases in which presentation occurs

more severely than usual, with complications such as per-
foration, intestinal obstruction, or major hematochezia.
ese more severe presentations may indicate more than
one agent in a synergistic interaction [3].
us, tuberculosis infection in the esophagus, a non-
prevalent site for this infection, could have resulted from
synergism with CMV causing an infection in a less probable
site with increased ulceration. e hypothesis of coinfections
is valid in less frequent and more aggressive presentations of
opportunistic diseases.

... Diagnosis of gastrointestinal TB can be quite challenging, especially in differentiating with other pathologies due to possible similarities in clinical, morphological, and histological features. One of the mimickers of gastrointestinal TB is CMV colitis, which is also an AIDS de ning event and ulceration is commonly seen in both pathologies [14]. Hence, awareness among healthcare providers is crucial to prevent misdiagnosis and delayed treatment. ...

Purpose Despite a decrease in tuberculosis (TB) incidence worldwide, TB is still the second leading cause of infectious disease deaths. Diagnosing gastrointestinal TB is challenging due to nonspecific symptoms and often negative tests. Our study aims is to analyse the clinical presentations, endoscopic and features, treatment, and outcome of gastrointestinal TB among people living with human immunodeficiency virus (PLHIV). Methods A systematic literature search was conducted on PubMed, ScienceDirect and Ovid SP from inception up until 31st January 2024 to identify relevant case reports. Descriptive statistics were summarized as percentages for categorical variables, and mean ± standard deviation for continuous variables. Binary logistic regression was used to analyse the predictors of mortality. Statistical analysis was conducted using IBM SPSS Statistics 26.0. Results A total of 44 cases from 41 case reports were included in this systematic review. The mean age was 36.23 ± 9.13 where 81.8% were male. Common clinical presentations reported were fever (63.6%), abdominal pain (61.4%) and weight loss (54.5%). Ileum (31.8%) was the most common anatomic location for gastrointestinal TB. The most common endoscopic features was visualized were ulceration (76.7%) followed by polyps (26.7%). The common histological features were granuloma (50%), caseating or necrotizing granuloma (42.1%), and mucosal inflammation (31.6%). 41 cases received anti-tuberculosis therapy while 19 cases underwent surgery. The mortality rate reported was 24.4%. Conclusion The diagnosis of gastrointestinal TB should be considered in PLHIV presenting with constitutional and gastrointestinal symptoms. Subsequently, comprehensive workup should be performed to confirm the diagnosis followed by prompt treatment.
... [9]. Endoscopic features associated with gastric CMV infection, including ulcers and erosions, were observed in most cases [10]. In the diagnosis of CMV-associated GI infection, it is crucial to detect the presence of the virus in the mucosa of the upper GI tract. ...
... Some studies have shown that patients infected with TB are up to 3 times more likely than those without TB to be coinfected with CMV. 6 TB has also been demonstrated to promote CMV reactivation in infected individuals by acting on CMV-specific T-cells and cytokines to aid reactivation. 7 There is also evidence to suggest that CMV coinfection can facilitate conversion from latent to active TB. 8 The incidence of TB in malignancy is highest in non-Hodgkin lymphomas such as BL. 9 TB involves the bowel in less than 5% of cases in the United States. ...

Bleeding from the small bowel can be challenging to identify by endoscopic or radiographic evaluation. We present the case of a patient with incompletely treated latent tuberculosis and medical history of T-cell lymphoma who developed gastrointestinal bleeding because of concurrent Burkitt lymphoma, tuberculosis enteritis, and cytomegalovirus enteritis. The interplay of these 3 diagnoses is discussed.

Gastrointestinal manifestations in HIV-infected patients constitute a common cause of morbidity and mortality. Since the introduction of ART, the incidence of opportunistic infectious diarrhea has decreased significantly. Chronic diarrhea is frequently seen in patients with advanced disease, causing complications such as severe malnutrition, dehydration, predisposal to secondary infections, and in some cases can be life threatening (Wilcox and Saag, Gut 57:861–870, 2008; Guidelines for the prevention and treatment of opportunistic infections in HIV-infected adults and adolescents [Internet]. [cited 2018 Dec 11]. Available from: https://aidsinfo.nih.gov/guidelines/html/4/adult-and-adolescent-opportunistic-infection/328/bacterial-enteric, 2017). Differentiation between infectious and noninfectious causes is key to improve patient survival as well as quality of life. Besides diagnostic-guided treatment when appropriate, prompt institution of ART is recommended in a majority of cases (Bennett et al., Mandell, Douglas, and Bennett’s principles and practice of infectious diseases, 2015; Oldfield, Rev Gastroenterol Disord 2(4):176–188, 2002).

To the best of our knowledge, tracheo-esophageal fistula complicating esophageal ulcers, other than due to tuberculosis have been rarely reported. Tracheo-esophageal fistula, secondary to AIDS-defining infectious diseases and neoplasia is regressing since the introduction of highly active antiretroviral therapy. It occurs as a complication of tuberculosis of the digestive tract and airways. Other infections causing deep esophageal ulcers include Cytomegalovirus, Herpes simplex virus type 2 and HIV. Several studies have reported resistances of VIH-1 to many antiretroviral drugs, making the occurrence of opportunistic gastrointestinal disease possible in patients treated with such drugs, particularly in the severely immunodepressed. The outcome is generally poor in the absence of treatment with an average survival rate of one to six weeks. We are reporting the case of a 43 years old Cameroonian man type-1 HIV infected patient classified CDC stage C3 who has been followed up for about 10 years, having being on combination therapy for about6 months. He presented with cough during swallowing, odynophagia and weight loss, complicating a medically treated tracheo-esophageal fistula, whose outcome was poor. Conclusion: Despite the various antiretroviral regimens available in developing countries, HIV-related digestive diseases remain a challenge with poor prognosis due to limited others therapeutic options. The diagnosis of tracheo-esophageal fistula should be considered in the context of a persistent cough during swallowing in patients with AIDS.

Spontaneous bronchoesophageal fistula in adults is a rare clinical entity. Most bronchoesophageal fistulae are due to malignancy, prolonged endotracheal intubation or trauma. Granulomatous infections like tuberculosis, HIV and mediastinitis are rare causes of acquired bronchoesophageal fistula. We report a case of a 50 year old man, treated for pulmonary tuberculosis 15 years ago, who developed a spontaneous bronchoesophageal fistula between the mid-esophagus and right main stem bronchus, having no history of malignancy or trauma. Surgical closure of the fistula was done and post operative recovery was uneventful. In this case, the bronchoesophageal fistula probably developed as a delayed sequela of pulmonary tuberculosis as the patient had no active signs of pulmonary tuberculosis clinically or histopathologically.

Esophageal tuberculosis is rare, constituting about 0.3% of gastrointestinal tuberculosis. It presents commonly with dysphagia, cough, chest pain in addition to fever and weight loss. Complications may include hemorrhage from the lesion, development of arterioesophageal fistula, esophagocutaneous fistula or tracheoesophageal fistula. There are very few reports of esophageal tuberculosis presenting with hematemesis due to ulceration. We report a patient with hematemesis that was due to the erosion of tuberculous subcarinal lymph nodes into the esophagus. A 15-year-old boy presented with hemetemesis as his only complaint. Esophagogastroduodenoscopy (EGD) revealed an eccentric ulcerative lesion involving 50% of circumference of the esophagus. Biopsy showed caseating epitheloid granulomas with lymphocytic infiltrates suggestive of tuberculosis. Computerised tomography of the thorax revealed thickening of the mid-esophagus with enlarged mediastinal lymph nodes in the subcarinal region compressing the esophagus along with moderate right sided pleural effusion. Patient was treated with anti-tuberculosis therapy (Rifampicin, Isoniazid, Pyrazinamide, Ethambutol) for 6 mo. Repeat EGD showed scarring and mucosal tags with complete resolution of the esophageal ulcer.

Oesophageal tuberculosis is a rare disease. Tuberculosis (TB) can cause dysphagia due to oesophageal ulcers, Tracheo-Oesophageal Fistulas (TOFs) and an extrinsic compression which is caused by the mediastinal lymph nodes. A 33-year-old gentleman was admitted to our hospital for the evaluation of fever, dysphagia and cough. His chest X-ray was suggestive of miliary tuberculosis. A CT scan of his chest revealed miliary tuberculosis, mediastinal lymphadenopathy and pneumomediastinum. His sputum AFB (acid-fast bacilli) test was positive. An upper gastrointestinal endoscopy revealed a large ulcer in the oesophagus with a fistulous opening which was suggestive of a tracheo-oesophageal fistula. A biopsy from the ulcer was positive for AFB. The test for HIV-1 was positive. A nasogastric feeding tube was placed and the Anti Tubercular Therapy ( ATT) was started. The main aim of this case report is to sensitize the clinicians about the fact that Tuberculosis can present with dysphagia, especially in HIV patients.

Background and Objectives: Tracheoesophageal/bronchoesophageal fistula is a rare clinical condition, and occurs due to a variety of disease processes. This report describes the clinical profile, management, and outcome of bronchoesophageal fistulas due to tuberculosis in five patients. Patients and Methods: Patients diagnosed with esophageal tuberculosis over the last eight years were included. Details regarding the demographics, symptomatology, barium swallow, upper GI endoscopy, with biopsy and high resolution computed tomography of the chest were recorded for patients with tracheoesophageal fistula. The diagnosis was confirmed by acid fast bacilli (AFB) positive fluid aspirate/brush cytology from the fistula, lymph node biopsy showing caseous necrosis or AFB bacillus and tissue tuberculosis culture and polymerase chain reaction (PCR). Results: There were five patients (four males and one female) with a mean age of 43.8 ± 17 years (range, 17 to 59 years). The mean duration of symptoms was 38 ± 7 days. The most common symptom was coughing on swallowing followed by dysphagia. Two patients had concomitant pulmonary tuberculosis; two had human immunodeficiency virus (HIV) infection, and one was a post-renal transplant. The diagnosis of tuberculosis was established in all five patients with esophageal cytology, lymph node biopsy, and tissue tuberculosis PCR. All the patients were successfully treated with a combination of antituberculous drugs (five patients), glue application on fistula (one patient), Percutaneous endoscopic gastrostomy (PEG) tube insertion (three patients), and surgery (one patient). [TAG:2]Conclusions[/TAG:2] : Tuberculous bronchoesophageal fistula is a rare complication and can be successfully managed predominatly with a combination of antituberculous treatment, PEG tube placement, and rarely surgery.

Benign esophagorespiratory fistula is a relatively rare condition in adults that poses a technical challenge to manage. This case series describes our experience in the treatment of benign esophagorespiratory fistula in 12 adults. A retrospective review of case records of 12 patients with benign esophagorespiratory fistula was done. There were eight tracheoesophageal fistulae and four bronchoesophageal fistulae. Among them, four fistulae were congenital, one was secondary to corrosive injury, three were due to foreign body (dentures), one was secondary to erosion because of prolonged endotracheal intubation, one was secondary to penetrating trauma, and two were infective in etiology. Of the 12 patients, there were nine males and three females. The mean age of presentation was 30.16 years (range 15-53 years). Nine patients had a definitive surgical intervention. The esophageal end of the fistula was managed by primary closure of the esophageal defect and reinforcement with pleural or intercostal muscle flap or a subtotal esophagectomy. The respiratory end of the fistula was dealt with by primary closure of the defect or by a novel technique of neomembranous airway formation, whereby the tracheal defect was closed with the help of a vascularized patch of the esophageal wall. The technique of this neomembranous airway formation is described in detail, and to our knowledge, this is the first time that this technique is being reported in the English literature. This technique is a novel method for definitive repair and can be considered as an option for repair of esophagorespiratory fistula with large defects.
