The objectives of this study were to describe the clinical presentations and outcomes of all HIV+ patients who presented to the Emergency Department (ED) with a chief complaint of abdominal pain and to compare the outcomes of those with advanced disease (CD4 < 200/mm(3)) to those with early or middle stage disease (CD4 >or= 200/mm(3)). We conducted a retrospective chart review in an urban municipal hospital ED and included subjects if they were HIV+ and had a chief complaint of abdominal pain. Demographic and clinical data were entered into a standardized database; patients with advanced disease were compared with those with early or middle stage disease. One hundred eight patient visits were reviewed. The mean age was 37 +/- 7.6 years with mean CD4 count of 263/mm(3); 44% had CD4 counts <200/mm(3). Abdominal pain of unknown etiology, gastroenteritis/diarrhea, and ulcer disease/gastritis/dyspepsia were the three most common diagnostic categories for all patients. With the exception of disseminated mycobacterial disease, there were no statistically significant differences between the two groups. AIDS-associated opportunistic infections represented only 10% of the ED diagnosis of those patients with advanced disease. Only 8% of patients required intra-abdominal surgical procedures, however, 37% were admitted compared with 18% of patients without HIV disease (p < 0.001). Patients infected with HIV presenting with abdominal pain most often have a non-HIV related cause of abdominal pain and infrequently require surgery. However, HIV+ patients are admitted at twice the rate of the non-HIV infected population.

Antibodies to Helicobacter pylori, Chlamydia spp. and Mycobacterium bovis were determined in patients with coronary heart disease, H. pylori-related dyspepsia, and tuberculosis, and healthy controls. Enzyme-linked immunosorbent assay was conducted with a glycine extract and CagA protein of H. pylori, chlamydial lipopolysaccharide and mycobacterial heat shock protein Hsp65. The prevalence of anti-glycine extract IgG in coronary heart disease patients was higher than in the tuberculosis group and controls, and the same as in dyspeptic patients. Anti-chlamydial IgG were more prevalent in the coronary heart disease group than in healthy subjects. There was no difference in the prevalence of anti-CagA IgG in the coronary heart disease group and controls or anti-Hsp65 IgG in the patients with coronary heart disease, dyspepsia, tuberculosis, and controls. Anti-glycine extract IgA (like anti-glycine extract IgG) were more prevalent in the coronary heart disease group than in the healthy group. The highest anti-glycine extract IgG/IgA and anti-chlamydial IgG titers were more frequent in coronary heart disease patients as compared with controls. Infections with H. pylori and Chlamydia spp. and enhanced production of antibodies to these pathogens may predispose to human atherosclerosis.

Gastroduodenal tuberculosis (GDTB) is rare in the West. Its presentation can be non-specific and often mimics other more common conditions such as peptic ulcer disease, malignancy and Crohn's disease. Our case describes a 33-year-old Indian immigrant who presented with a 3-year history of dyspepsia and underwent balloon dilation for gastric outlet obstruction (GOO). While biopsies from the duodenum revealed only non-caseating granuloma, a high index of suspicion was maintained and colonoscopy, performed despite the absence of lower gastrointestinal symptoms, revealed a single discrete nodular and ulcerated area in the proximal transverse colon; this eventually grew Mycobacterium tuberculosis. Our patient avoided undergoing major surgery and was successfully treated with balloon dilation and antitubercular medication. We highlight the importance of having a concerted, proactive approach to diagnosis. We discuss the therapeutic challenges involving this rare condition and explain the rationale for high-dose antisecretory therapy.

A 25-year-old male presented with hematemesis, epigastric pain, and melena. He had dyspepsia with significant weight loss for 3 months period. On clinical examination, he was pale with no organomegaly or lymphadenopathy. The X-ray chest was normal, and ultrasound abdomen was normal. Upper GI endoscopy revealed nodularity and ulceration along proximal part of lesser curvature of the stomach. CT scan abdomen showed thickening of lesser curvature just below gastro-esophageal junction. The biopsies were negative for malignancy. Repeat upper GI endoscopy showed a nonhealing ulcer, on repeat well biopsies taken from the base of ulcer primary gastric tuberculosis was diagnosed. It showed many epithelioid cell granulomas and multinucleated giant cells with caseous necrosis on histology. Acid-fast bacilli on Zeil Neelsen staining and TB PCR were positive for Mycobacterium tuberculosis. He was put on four-drug anti-tuberculous treatment. On follow-up, the patient gradually improved and regained weight. Repeat upper GI endoscopy done after 8 weeks showed healing of the ulcer with decrease in nodularity.
