The yield of upper gastrointestinal endoscopy (esophago-gastroduodenoscopy; EGD) in human immunodeficiency virus (HIV)-infected patients based on presenting symptoms has not been well studied. We studied consecutive patients with documented HIV infection undergoing EGD at a large innercity hospital between August 1, 1990 and December 31, 1993; all had presenting symptoms and indications for EGD prospectively recorded at the time of EGD. All endoscopic abnormalities were routinely subjected to biopsy, and extensive histopathological evaluation was performed. EGD was considered helpful when the findings stimulated specific therapeutic intervention other than antifungal or antacid medications. The specific indications for EGD in 156 patients were as follows: esophageal symptoms, 102 patients (65%); abdominal pain, 18 (12%); upper gastrointestinal bleeding, 25 (16%); refractory nausea and vomiting, 11 (7%). Overall, pathologic findings were identified in 116 patients (74%): in refractory esophageal symptoms, 82%; upper gastrointestinal bleeding, 92%; abdominal pain, 39%; nausea and vomiting, 27%. EGD with biopsy identified a specifically treatable opportunistic disorder other than Candida in 80 patients (51%), including idiopathic esophageal ulcer (22%) or viral esophagitis and/or duodenitis (29%). EGD was not helpful in 22.3% of cases, those involving Candida (12.3%) and peptic ulcer disease (PUD)-related causes (10%). The mean CD4 count of patients with opportunistic pathologic findings (24/mm3, n = 79) was significantly lower than that of patients with PUD/gastroesophageal reflux disease (GERD) (167/mm3, n = 9) or negative EGDs (165/mm3, n = 35). Overall, the results of EGD influenced patient management in 78% of cases. We conclude that selective symptom-specific use of EGD, particularly in patients with esophageal symptoms refractory to antifungal therapy or gastrointestinal bleeding, usually identifies specifically treatable abnormalities, whereas EGD is less useful for the evaluation of abdominal pain or nausea and vomiting.

In contrast to the well known chlorpromazine-induced cholestatic hepatitis, we report the case of a schizophrenic patient who presents a cytolytic hepatitis, without any prior hepatic disease. Mr G. was first hospitalized for depressive symptomatology. A pseudo-nevrotic schizophrenia was diagnosed. Pretherapeutic clinical and biological data were normal. A treatment with chlorpromazine 400 mg/day was given. At day 8, the patient was still anxious and began to be agitated. An increase to 500 mg/day of chlorpromazine posology and an addition of haloperidol 200 mg/day was implemented. At day 10, the following clinical symptoms appeared: 38.6 degrees C fever; headache; myalgia; epigastralgia and hypocondrium pain. Biological hepatitis disturbances (ALAT, 984 U/L; ASAT, 414 U/L) and hypereosinophilia with normal white cell count were found. Clinical and biological investigations were normal. Blood-culture, A, B, C hepatitis, HIV and CMV serologies were negative. Neuroleptic treatment was discontinued. Evolution to normality of the disturbances and biological data suggested a cytolytic hepatitis. Mr G... remained treated with flupentixol without side-effects. Phenothiazine-induced cholestatis is frequent, mild, and recovers spontaneously. The biological mechanism is supposed to be immunologic. Prevalence of biological hepatic disturbances is 10 to 20% with chlorpromazine in long-term treatment. More often, symptomatology is the same; jaundice, pruritus, abdominal pain, fever. Although pharmacological data suggest for a cytotoxic activity of phenothiazines, cytolytic hepatitis is poorly described. Maximum range of transaminase blood level reported in previous studies is about 400 U/l. This level is not clearly correlated with hepatic cell lysis. Few cases of hepatic necrosis have been reported. In all cases, preexistent hepatic injuries were observed. Chlorpromazine-induced cytolytic hepatitis is uncommon and cholestatic hepatitis mild. Biological hepatic parameters investigations remain necessary during neuroleptic treatment.

A cohort of 12,501 adults aged 15-54 years was randomly selected from 12 rural communities in Mwanza region, Tanzania, in 1991-92 and followed for 2 years to assess the contribution of HIV/AIDS to mortality in the region. HIV seroprevalence in the sample was 4% at baseline. 73 of the 196 deaths recorded over the period occurred among HIV-positive individuals. Mortality rates per 1000 person-years were 6.0 among the HIV-seronegative and 93.5 among the HIV-seropositive. The age-adjusted mortality rate ratio was 15.68 overall. 35% of overall mortality was attributed to HIV infection, 53% among those age 20-29 years. Verbal autopsies administered for each death reported showed that HIV-positive deaths were significantly associated with fever, rash, weight loss, anemia, cough, chest pain, abdominal pain, and headache. The specificity of individual symptoms, however, was low. The World Health Organization clinical case definition of AIDS was satisfied for only 13 deaths, of which seven were HIV-positive at baseline. HIV/AIDS was mentioned during the verbal autopsy interview by only seven respondents as being associated with a given death.

Sclerosing mesenteritis is a rare, idiopathic, and benign mesenteric lesion that is characterized by fat necrosis, fibrosis, and chronic inflammation. We report a case of sclerosing mesenteritis presenting as recurrent abdominal pain in an HIV-positive patient. Because of the wider differential diagnosis in such cases, the patient underwent an extensive workup culminating in a laparoscopy with biopsy. Tamoxifen has been shown to be useful in the treatment of desmoid tumors and idiopathic retroperitoneal fibrosis. We present the first case of sclerosing mesenteritis to respond to tamoxifen therapy. Because this drug is relatively safe and simple to dose, its utility as therapy for patients with this benign but debilitating disease should be considered.

It's well known that patients was acquired immunodeficiency syndrome (AIDS) can develop various kinds of hepatobiliopancreatic diseases, for causes related to AIDS and for causes not related to HIV infection. The authors describe a case to their attention due to a suspected acute pancreatitis. The patient presented with abdominal pain, increased serum alkaline phosphatase and amylase levels. Serological test and stool concentration didn't show any opportunistic infection (Cytomegalovirus, Cryptosporidium). Abdominal ultrasonography showed enlargement of the head of the pancreas, gallbladder with biliary sludge, and a little dilatation of the biliary tree. The patient didn't feel better despite the medical treatment, so considering the probability of the migration of calculus, the patient underwent cholecystectomy. After the operation the patient felt better quickly. This case confirms the presence in HIV patients of pancreatitis for causes unrelated to AIDS like cholelithiasis as we showed, alcoholism, hypercalcemia, and the importance of an opportune surgical treatment that was resolutive.

We worked with 185 middle-class patients above 18 years of age, both sexes, who presented diarrhea and/or chronic gastrointestinal disorders. The faeces were collected serially in formol 10% and processed in the following way: direct microscopy, with and without wet staining, concentration by Ritchie's method, 1% safranine technique for a specific investigation of Cryptosporidium sp., and faecal sieving macroparasites. Twenty eight point six of the studied patients showed at least one enteroparasite in their faeces, 48 harboured one parasite and 5 harboured two parasites. The following parasites were found and their corresponding percentages in the entire studied population are given below: Blastocystis hominis 15.7%, Giardia lamblia 7.5%, Cryptosporidium sp. 1.6%, Entamoeba coli 3.3%, Chilomastix mesnilii 1.1%, Ancylostoma duodenale-Necator americanus 0.5%, Ascaris lumbricoides 0.5%, Enterobious vermicularis 0.5% y Endolimax nana 0.5%. The most frequently found enteroparasites in the positive patients were B. hominis and G. lamblia. Cryptosporidium sp. was diagnosed in only three patients. The source of infection could be presumed in all of them. The symptomatology coincided with that described for this coccid in the bibliography. In spite of the fact that they were HIV seronegative patients the diarrhea was not self-limiting, but the immunologic profile of their relatives remained unknown and no other cause of immunosuppression could be detected with justified chronicity. The treatment with spiramycin was effective. Giardiasis was found in 17 patients, and the source of infection could not be inferred in any of them. They all had chronic diarrhea and their most frequent symptoms were abdominal pain, metallic taste, flatulency and nausea. Most of these patients were harboured one parasite, and only 2 of them simultaneously presented another faecal parasite associated to G. lamblia. Treatment with metronidazole was successful in all of them. Twenty nine patients were found to have B. hominis. The source of infection could not be inferred, this amoeboid was present as the only parasite in 25 patients. Predominant symptoms were flatulence, abdominal distention and colis. All patients suffered from chronic diarrhea, alternating, in some cases, with constipation. Good therapeutic results were obtained with metronidazole. Considering that one third of the patients examined presented faecal parasites associated to chronic disorders, it is important to insist on the detection of parasites to chronic disorders, it is important to insist on the detection of parasites using appropriate diagnostic techniques since the application of specific therapy made their eradication possible as well as relieving the patients' symptomatology.

Two cases of colonic tuberculosis (TB) isolated in two elderly, not HIV seropositive women, presenting unspecific clinical manifestations (constitutional syndrome, fever, abdominal pain and diarrhea) and stenosis of the colon in diagnostic imaging techniques are presented. In the second case, endoscopy showed stenosis of the colonic lumen and inflammatory mucosa, the biopsy of which demonstrated granulation tissue with no signs of specificity (in the first case, technical problems did not allow the colonoscopy to reach the affected site). In both cases, diagnosis was performed postoperatively by study of the surgical pieces. Biopsy showed granulomas with acid-alcohol resistant bacilli. Both patients responded favorably to tuberculostatic treatment.

This report presents the first case described in the English literature of dual infection with Cryptococcus neoformans and Streptococcus pneumoniae in the cerebrospinal fluid of an AIDS patient. The patient was a 32-year-old, HIV-positive South African woman who had been diagnosed with disseminated tuberculosis 5 months prior to the index admission. Her chief complaints at presentation were abdominal pain, chronic diarrhea, and vaginal discharge, suggesting a diagnosis of pneumonia and pelvic inflammatory disease. Persistence of confusion led to a lumbar puncture; gram-positive and budding yeasts were observed and subsequent India-ink staining revealed capsulated yeast typical of C. neoformans. S. pneumoniae and C. neoformans were cultured 24 and 48 hours, respectively, after incubation. The woman died within 24 hours of hospital admission, precluding further investigation. It is presumed that this woman already had disseminated cryptococci at the earlier presentation, but was incorrectly diagnosed as having tuberculosis. The finding of pneumococci, in the absence of inflammatory cells in cerebrospinal fluid, suggests the terminal event was fulminant pneumococcal meningitis in the setting of chronic cryptococcal meningitis. This case supports the importance of performing both the Gram- and India-ink stains and cryptococcal antigen test on cerebrospinal fluid specimens from immunocompromised patients, even when biochemical and cellular parameters are normal.

Travel and tourism are associated with an increased risk of sexually transmitted infections (STIs) and unwanted pregnancy. This article offers guidelines for health professionals on pre-travel counseling and outlines steps in the clinical management of returning travelers who have been exposed to STIs or pregnancy. The imperative for controlling STIs is particularly urgent now that an epidemiologic link between STIs and vulnerability to HIV infection has been established. Much can be done before a trip abroad in terms of prevention, including the provision of condoms and leaflets explaining the risks of unprotected sex while on holiday or a business trip. Patients should be questioned about their sexual behaviors before, during, and after travel and those who have taken sexual risks while traveling should be offered screening for STIs. The STI-related conditions addressed in this article include vaginal discharge, lower abdominal pain, urethral discharge, scrotal pain, genital ulcer disease, inguinal bubo, and genital warts. Recommended treatment regimens for the most prevalent reproductive tract infections are outlined.

The colon is a frequent site of gastrointestinal complications in patients with HIV infection, and these colonic disorders increase in frequency as immunodeficiency worsens. The most common clinical manifestations of colonic disease in AIDS are diarrhea, lower gastrointestinal bleeding, and abdominal pain. Toxic megacolon, intussuseption, typhlitis, idiopathic colonic ulcer, and pneumatosis intestinalis also have been described. In the HIV-infected patient with preserved immunity, the most common cause of colitis is bacterial, but as the degree of immunodeficiency worsens, opportunistic pathogens (CMV, protozoa, mycobacteria, fungi) and neoplasms become more frequent. The frequent use of antibiotics, chemotherapeutic agents, and frequent hospitalization increase the susceptibility to cf2Clostridium difficule cf1colitis. Endoscopy plays an integral role in the management of many colonic disorders in AIDS.
