Four patients with acquired immunodeficiency syndrome (AIDS) (CDC group IV) were investigated for biliary disease because of the presence of both severe upper abdominal pain and raised levels of serum alkaline phosphatase. None was clinically jaundiced. Upper abdominal ultrasound was abnormal in three. All had endoscopic retrograde cholangiographic evidence of both an intrahepatic sclerosing cholangitis suggestive of primary sclerosing cholangitis and an irregular suprapapillary common bile duct dilation suggestive of papillary stenosis. Three had evidence of gastrointestinal cryptosporidiosis and two of disseminated cytomegalovirus infection. Endoscopic sphincterotomy, performed in two patients, gave good pain relief. We propose the name 'AIDS sclerosing cholangitis' for this form of secondary cholangitis. The cause of this disorder remains unclear. Recent evidence is discussed which suggests that it is not due to HIV itself but to an opportunistic infection. Cryptosporidium appears to be the most likely candidate.

Adequate measures of diarrheal disease are important to assess severity for clinical use and outcomes research. We developed a questionnaire to assess diarrhea severity and complications, and administered it to 205 HIV positive patients with diarrhea, fever, or weight loss. Noteworthy variations in stool form were reported by individuals and across subjects. Self-reported diarrhea correlated with the occurrence of any stool pictured without form. However, verbal descriptors "loose" and "semiformed" had little value in assessment of diarrheal disease. Both verbal and pictorial stool descriptors correlated well with diarrhea complications (pain, urgency, tenesmus, incontinence, and nocturnal diarrhea). By factor analysis, discomfort and nondiscomfort diarrhea complications loaded on different factors, consistent with clinical experience that discomfort is a distinct problem in diarrheal disease. In summary we have developed an instrument to precisely characterize diarrhea severity that correlates well with clinically important events such as incontinence and abdominal pain.

Five cases of acalculous cholecystitis associated with Cryptosporidium intestinal infection in HIV infected patients are reported. Clinical, Biological and Microbiological features as well as imaging studies are described. All the patients were males. Risk factors for HIV infection included previous I.V. drug abuse (3), homosexuality (1) and unknown (1). On admission a similar history of weight loss, fever, abdominal pain, diarrhea, anorexia and asthenia, together with biological data of cholestasis, was present in all patients. Ultrasound studies showed a distended gallbladder without calculi and a thickened wall, the bile duct being dilated in four of five cases. Cryptosporidium were found in stool specimens of all patients as well as histologically in one of two patients who underwent surgery while CMV was shown in the other one. Endoscopic retrograde cholangiography was performed in four cases showing a congestive, edematous and protruded papila in three patients, being normal in the fourth with a choledocal stenosis.

Radiological features of sclerosing cholangitis are an uncommon but well recognised complication of HIV infection in homosexual males. In this report we document the clinical features and course of the disease in four patients. Four homosexual males with established AIDS were referred in 1990-92. Three of the four had intractable upper abdominal pain which was poorly responsive to opiates. Three of the patients had diarrhoea and all had weight loss. The diagnosis of AIDS related cholangitis was confirmed by endoscopic retrograde cholangiography in three cases, but in only one patient was there no evidence of biliary disease on ultrasound scanning. In the two cases with cholangiographic features of papillary stenosis, endoscopic sphincterotomy was carried out and there was subsequently a dramatic improvement in the abdominal pain. Three of the patients had evidence of gastrointestinal infection with Microsporidia (1) or Cryptosporidia (2). All the patients died within 2-9 months of the diagnosis of cholangitis, but none of the deaths resulted from hepatobiliary disease.

The diagnosis of cytomegalovirus intestinal disease in patients with HIV (human immunodeficiency virus) infection frequently raises diagnostic problems in view of the absence of definite pathological, serological or virological markers of active CMV infection. We describe the case of a 47-year-old man with a CMV colitis which illustrates several diagnostic and therapeutic problems and that was complicated by an intestinal perforation. We emphasize that in HIV+ patients with chronic diarrhea, the presence of abdominal pain should suggest the possibility of a CMV colitis and that in such cases a colonoscopy with biopsies of the right colon should be performed, in view of the higher frequency of the typical histopathological changes at this level. On the other hand, this case presented a marked thickening of the colon wall, simulating pseudotumoral images on CAT scans, as recently described in literature. The therapeutic possibilities as well as the complications of CMV colitis are discussed in the context of the occurrence of an ileal perforation, which represents the first report of this complication in Portuguese literature and which had the particularity of having a long survival after surgery in comparison with the previous cases described in international literature.

Children with HIV disease and gastrointestinal disease should be evaluated for enteric pathogens. Bacterial, protozoal, and viral agents can cause chronic diarrhea, abdominal pain, gastrointestinal bleeding, and contribute to growth retardation. This article presents an approach to the evaluation of the HIV-infected child with gastrointestinal symptoms. Therapeutic and nutritional interventions are discussed with emphasis on the multidisciplinary approach required to initiate successful management.

The prevention of cerebral toxoplasmosis and of Pneumocystis carinii pneumonia is an essential objective in the management of patients infected with HIV. Given that roxithromycin is active in vitro against Toxoplasma gondii and that in 1989 Dolermann reported the effective treatment of P. carinii respiratory infections with erythromycin, a randomized pilot study was undertaken in 52 patients infected with HIV. Patients were treated with either: a monthly dose of pentamidine aerosol (300 mg); roxithromycin once a week (300 mg t.i.d.); or a combination of pentamidine aerosol and roxithromycin. Intention to treat analysis was applied to these 52 patients, all of whom received at least one treatment dose. Five out of 18 patients treated with pentamidine aerosol, 1/17 patients treated with pentamidine aerosol + roxithromycin and none of the 17 patients treated with roxithromycin developed cerebral toxoplasmosis (p = 0.038). P. carinii pneumonia was diagnosed in one patient in the pentamidine aerosol-treated group, in one patient treated with roxithromycin and in none of the patients treated with pentamidine aerosol + roxithromycin (non-significant difference). Four cases of Mycobacterium tuberculosis and Mycobacterium avium-intracellulare infection were seen in the pentamidine aerosol-treated group (p = 0.028) and none in the roxithromycin groups. Adverse events leading to the discontinuation of treatment occurred in 5/34 (14.7%) patients treated with roxithromycin. Nausea, abdominal pain and raised transaminases occurred in four patients and a skin allergy in the final patient. Roxithromycin appears to be effective in the prevention of pulmonary pneumocystis infection and of cerebral toxoplasmosis in HIV-infected patients. However, these results require confirmation in a larger study.

A 33 year old patient was admitted to the hospital because of deteriorated general condition, upper abdominal pain and progressive dyspnea. He had a positive HIV-serology associated with i.v. drug abuse. The CDC classification on admission was B1. There was no history of opportunistic infections, the patient had refused all prophylactic treatment. The physical examination showed an elevated central venous pressure, decreased breath-sound and percussible dullness, the liver was enlarged and a tumor was palpable on chest. The x-ray of the thorax confirmed a pleural effusion. Cytology of the effusion revealed blasts of malignant non-Hodgkin's lymphoma of B-cell type. A CT-scan of the thorax and abdomen showed a tumor mass in the right ventricle and superior vena cava, a pleural effusion and multiple lesions in the liver. The patient refused a palliative chemotherapy with vincristine and prednisone and died few days after admission.

For identification of the features of disseminated Mycobacterium avium complex (DMAC) in human immunodeficiency virus (HIV)-infected children, a retrospective medical record review of 31 long-term survivors with transfusion-acquired HIV was conducted. Nine patients developed DMAC defined as positive isolation of M. avium complex from peripheral blood. DMAC was diagnosed in patients 51 to 132 months of age (mean, 101). The time from HIV-infecting transfusion to DMAC diagnosis ranged from 37 to 132 months (mean, 92) and survival from the time of DMAC diagnosis ranged from 4 to 21 months (mean, 10). Selected laboratory and clinical measures in DMAC-positive and DMAC-negative subjects were compared. DMAC-positive patients had significantly lower CD4+ T cell counts and higher HIV p24 antigen concentrations than DMAC-negative patients at comparable times. Increased percentages of circulating leukocyte band forms and increased aspartate aminotransferase values were seen more often in DMAC-positive patients. Fever and abdominal pain were the only clinical features seen more often in DMAC-positive than in DMAC-negative patients. At the end of the study period overall survival of DMAC-positive patients was less than that of DMAC-negative children, at 33% vs. 73%. DMAC occurs in profoundly immunocompromised children with advanced HIV disease and significantly affects survival. The clinical and laboratory features of DMAC are relatively nonspecific and a high index of suspicion in patients with markedly reduced CD4+ T cells is essential.

We describe five cases of gastrointestinal leishmaniasis in patients with human immunodeficiency virus infection and review 10 additional cases reported in the literature. All of the patients had CD4+ cell counts of < 200/mm3, and AIDS had been previously diagnosed for 12 patients. Fever and splenomegaly were present in 46% of cases. Thirteen patients had digestive symptoms; these symptoms included diarrhea (6), dysphagia and/or odynophagia (6), abdominal pain (2), epigastric pain (2), gastrointestinal hemorrhage (1), and rectal discomfort (1). The regions of the digestive tract most frequently affected by Leishmania organisms were the duodenal mucosa (90%) and the gastric mucosa (75%). Endoscopy showed normal-appearing mucosa in 45% of cases. In 10 cases the diagnosis of visceral leishmaniasis was first made by biopsy of the gastrointestinal mucosa. In most cases treatment with antimonial agents was not effective.
