An autopsy case of clostridial gas gangrene occurring in a 54-year-old man with colon adenocarcinoma, liver cirrhosis, and diabetes mellitus is reported. The patient died 4 days after the onset of symptoms with episodes of vomiting and abdominal pain. Gangrene of both hips and perineum, hemolysis, renal failure, and disseminated intravascular coagulation were the dominant clinical features. Clostridium septicum was isolated from the subcutaneous tissue fluid. Adenocarcinoma of the ascending colon with ulceration found at autopsy was supposed to be an entry of the organism. Histologically, lesions of subcutaneous tissue and muscles were characterized by the absence of inflammatory infiltrates in spite of extensive necrosis. A summary of 35 cases of gas gangrene hospitalized to the Osaka University Hospital for the past 16 years indicates that clostridial gas gangrene patients with underlying diseases such as malignant neoplasm, diabetes, liver cirrhosis or immunodeficiency have a relatively poor prognosis.

Three cases of cryptosporidiosis in children are described. Abdominal pain without concomitant acute diarrhoea, was the main clinical symptom. No other intestinal pathological agent was isolated. All children were males, aged between 25-27 months, living in urban area and with a high socioeconomic level. They went to day nurseries and only one was contacted with home animal. This last child had a previous giardiasis treated with metronidazole. Nutritional status was normal. Neither humoral nor cellular immunodeficiency was detected. Cryptosporidium muris isolation was performed with Ziehl-Neelsen modified technique. All recovered with negativity of abdominal pain and bacteriologic controls, using solely dietetic measures.

A 31-year-old Frenchman had an acquired immunodeficiency syndrome (AIDS) with profound depression of cellular immunity and relative sparing of humoral immunity. The clinical picture included intractable secretory diarrhoea, vomiting, abdominal pain, and weight loss. Gastrointestinal cryptosporidiosis was present and a perfusion technique showed profuse secretion of fluid in the proximal small bowel. The patient also had recurrent Salmonella typhimurium septicaemia, cytomegalovirus infection, and cerebral toxoplasmosis and he died within 13 months. This patient did not belong to any of the groups known to be affected by this type of acquired immunodeficiency (homosexuals, drug addicts, haemophiliacs, Haitians) but had been transfused with Haitian blood 4 years before onset of symptoms. This case supports the notion that some forms of AIDS may be transmitted by blood, with a long incubation period.

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.

Two cases are reported of hepatic tuberculous abscesses (HTBA) in patients infected with the human immunodeficiency virus (HIV), stressing the rarity of this location. Likewise, a review is made of cases reported in the literature. Our two patients presented with a prolonged febrile condition, with constitutional symptoms and nonspecific abdominal discomfort. In one patient the hepatic location was accompanied by a pulmonar location too. The course of the patients was good and symptoms subsided with tuberculostatic therapy. To note the possibility of finding hepatic tuberculous abscesses in HIV patients with prolonged fever and nonspecific abdominal pain more frequently than considered until now.

In a phase I/II study, 7 levels of 3TC therapy (from 0.5 to 20.0 mg/kg/day) were studied in 104 asymptomatic and mildly symptomatic human immunodeficiency virus-infected patients with CD4 cell counts < or = 400 x 10(6)/L. Mild and transient episodes of diarrhea, headache, fatigue, nausea, and abdominal pain were the most frequent events reported. No dose-limiting toxicities were observed. Small and transient increases in CD4 cell counts were detected during the first 4 weeks of treatment. These were followed by progressive declines during prolonged therapy. Sustained decreases in beta 2-microglobulin, neopterin, and p24 antigen levels were seen over the 52-week study. There was no consistent dose-response correlation for any surrogate marker. Penetration of 3TC into cerebrospinal fluid (CSF) was in the same range as reported for ddC and ddI; the mean CSF-to-serum ratio was 0.06. These findings indicate that 3TC exhibits an excellent safety profile and has antiretroviral activity at the dosages studied.

Many patients with acquired immune deficiency syndrome (AIDS) and abdominal pain are evaluated by the surgeon, and the majority have gastroenteritis, which can be treated with specific antimicrobials. There are some, however, who need more extensive investigation or who have an intra-abdominal infective process that requires surgical treatment. The one and a half decades of experience with human immunodeficiency virus (HIV) and AIDS has defined the role of the surgeon in treating patients with HIV. Major infective processes that may require surgical involvement include cytomegalovirus infection of the intestinal tract; appendicitis, which may be due to opportunistic infections; spontaneous bacterial peritonitis; cholecystitis; and obstructive jaundice with underlying sclerosis of the biliary tree. Early diagnosis and prompt surgical treatment are critical in the management of HIV-infected patients. For example, cytomegalovirus affecting the gastrointestinal tract may lead to perforation with the development of generalized fecal peritonitis; the clinical presentation of acute appendicitis in HIV patients may not include the usual rise in white blood cell count; and bacterial peritonitis in patients with AIDS may be caused by opportunistic pathogens or, as in the classical case, a single gram-negative bacillus or pneumococcus. This review article focuses on intra-abdominal infections in patients with HIV and AIDS.

Tuberculosis (TB) is the most common opportunistic infection worldwide in human immunodeficiency virus (HIV)-infected patients. Intraabdominal TB includes lymphadenopathy and focal lesions of solid viscera. Symptomatic expression of tuberculous invasion of the pancreas (supplemented by demonstration of a mass on imaging) is rare among HIV-infected patients. We report the case of an HIV-infected patient with a tuberculous pancreatic abscess and review nine similar cases. All patients presented with persistent fever and abdominal pain. The diagnosis was made on the basis of detection of pancreatic mass lesions on computed tomographic (CT) scans and the results of cultures and/or acid-fast stains of peripancreatic abscess material and/or other body fluids. Despite an excellent response to antituberculous therapy, three patients died of unrelated causes. In the setting of a febrile illness with abdominal symptoms, tuberculous pancreatic abscess should be considered in the differential diagnosis for HIV-infected patients with a CT-identified mass lesion.

We conducted a double-blind, randomized phase II study to evaluate the safety and activity of combination therapy with N-butyl-deoxynojirimycin (SC-48334) (an alpha-glucosidase I inhibitor) and zidovudine versus zidovudine alone. Patients with 200 to 500 CD4 cells/mm3 who tolerated < or = 12 weeks of prior zidovudine therapy received SC-48334 (1000 mg every 8 h) and zidovudine (100 mg every 8 h) or zidovudine and placebo. Sixty patients received combination therapy and 58, zidovudine and placebo. Twenty-three patients (38%) and 15 (26%), in the combination and zidovudine groups, respectively, discontinued therapy (p = 0.15). The mean SC-48334 steady-state trough level (4.04 +/- 0.99 micrograms/ml) was below the in vitro inhibitory concentration for human immunodeficiency virus (HIV). The mean increase in CD4 cells at week 4 was 73.8 cells/mm3 and 52.4 cells/mm3 for the combination and zidovudine groups, respectively (p > 0.36). For patients with prior zidovudine therapy, the mean change in CD4 cells in the combination and zidovudine groups was 63.7 cells/mm3 and 4.9 cells/mm3 at week 8 and 6.8 cells/mm3 and -45.1 cells/mm3 at week 16, respectively. The number of patients with suppression of HIV p24 antigenemia in the combination and zidovudine groups was six (40%) and two (11%) at week 4 (p = 0.10) and five (45%) and two (14%) at week 24 (p = 0.08), respectively. Diarrhea, flatulence, abdominal pain, and weight loss were common for combination recipients.(ABSTRACT TRUNCATED AT 250 WORDS)

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.
