Breast-feeding as a route of HIV-1 transmission during infancy but also as a protective measure against early childhood morbidity has been investigated prospectively in children born to HIV-1-seropositive mothers and control children born to age- and parity-matched HIV-1-seronegative women. The mothers of all study children had been enrolled antenatally at a maternity hospital in Kinshasa, Zaire, which served a relatively affluent group of women who sometimes chose not to breast-feed their infants. In 106 children born to HIV-1-seropositive women, the rate of HIV-1 transmission was 21% in 28 infants exclusively breast-fed, 19% in 68 infants both breast- and bottle-fed and 0% in 10 infants who were bottle-fed only (P = 0.35). In contrast, non-HIV-1-infected children of both HIV-1-seropositive and HIV-1-seronegative mothers who were exclusively breast-fed compared with uninfected children who were not exclusively breast-fed had significantly lower incidence rates of acute diarrhea, fever and lower respiratory tract infection. The lack of a dose-response effect between breast-feeding and perinatal HIV-1 transmission and the presence of a protective effect of breast-feeding against common causes of early childhood morbidity and mortality support the current World Health Organization recommendation that breast-feeding should continue to be promoted in all developing countries, including those with high HIV-1 prevalence rates in women of childbearing age.

We present a case of colonic histoplasmosis in a young HIV antibody-positive homosexual male who presented with acute diarrhea. The diagnosis was made by flexible sigmoidoscopy with biopsy which revealed organisms morphologically consistent with Histoplasma capsulatum, and was later confirmed by fungal culture of the biopsy specimens. At colonoscopy, skip areas with plaques, ulcers, and a pseudopolyp were observed. The colitis resolved endoscopically after a 6-wk course of intravenous amphotericin B, and the patient has had no recurrence of symptoms while on maintenance therapy with amphotericin B. However, the organisms continue to be noted on biopsies of normal-appearing areas in the rectum and sigmoid 5 months after diagnosis. Colonic involvement with H. capsulatum, an organism endemic to the Midwest, may be seen more frequently as the total number of cases of HIV-infected individuals increases in this region.

In a study involving 104 children hospitalized with diarrhoea, 9% were infected with oocyst Cryptosporidium spp. add 56% with such yeast-fungus as Candida (C. Candida 38%). The manifestations noted in cryptosporidiosis infected children are acute diarrhea, vomiting and hyperthermia. One subject out of five who were tested for antibody to HIV appeared to be antibody positive. The patients immunity from the disease was not checked. A mycological test must be systematically carried out in case of children diarrheal outbreak.

We studied 388 homosexual or bisexual men from the Baltimore-Washington area to define the spectrum of enteric pathogen carriage in a population at high risk for "gay bowel syndrome" in association with human immunodeficiency virus infection. Seventy-seven patients with acquired immunodeficiency syndrome, 68 gay men with symptoms of acute diarrhea or proctitis, and 243 gay men without gastrointestinal symptoms and participating in a natural history study of human immunodeficiency virus infection were selected for study. Approximately 12% of the asymptomatic men harbored at least one enteric pathogen; the most frequently recovered were Chlamydia trachomatis, herpes simplex virus, and Giardia lamblia. Men carrying a pathogen were more likely to be human immunodeficiency virus seropositive (48%) than men without a pathogen (25%) (p = 0.018), more likely to have fewer T helper cells (p = 0.015), and more likely to have a mucopurulent exudate (p = 0.014). We recovered an agent of enteric disease from 68% of gay men presenting with diarrhea or proctitis. Campylobacter species, herpes simplex virus, Neisseria gonorrhoeae, C. trachomatis, G. lamblia, and Shigella species were identified most frequently. The most common pathogen associated with diarrhea in acquired immunodeficiency syndrome was Cryptosporidium (16% of 49 cases). Other agents identified were Clostridium difficile, Vibrio parahemolyticus, Campylobacter species, G. lamblia, Isospora, and cytomegalovirus. Approximately half of the identifiable etiologic agents of diarrhea in acquired immunodeficiency syndrome patients were treatable with antibiotics, but these agents required special culture procedures for detection.

A study was conducted at the Ndola Central Hospital, Zambia, in 1987 to determine whether human immunodeficiency virus (HIV) infection increases the risk or severity of infection with falciparum malaria in patients aged 12 years and over. The 170 patients examined all presented with symptoms suggestive of malaria, including fever, chills, rigors, headaches, joint pains, myalgia, acute diarrhea, and vomiting. 67 (39%) were diagnosed as having falciparum malaria and 28 (17%) were positive for the HIV antibody. The prevalence of malarial parasitemia in patients with HIV antibodies was lower than that in patients without such antibodies (29% versus 42%, respectively), and differences in densities of parasites also failed to provide evidence of increased susceptibility to malaria in patients infected in HIV. There were no significant differences in antibody titers to P falciparum in patients who were positive for HIV antibody and in those who were negative, whether or not they had parasitemia. The earlier finding of a significant association between malaria and HIV infection is now believed attributable to false positive results with the 1st enzyme linked immunosorbent assays and to interpretation difficulties with the Western blot test. Of interest is the fact that 20 patients in this study had symptoms suggestive of malaria, but had negative results for parasites and positive results for HIV antibody. This indicates that many patients with HIV infection may be presenting with an illness clinically similar to malaria before acquired immunodeficiency syndrome (AIDS)-related complex or AIDS is recognizable.

Lymphoadenopathic Syndrome (LAS), diagnosed also with histologycal studies, is described in a polytransfused 11-year old boy affected by beta-thalassemia major. After three days of the admission he suffered a serious acute diarrhea by Aeromonas hydrophila, an opportunistic enteric bacteria demonstrated, up to date, in immunocompromised patients and never in AIDS patients. It is important to remark that beta-thalassemic patients are at high risk from HIV infections, either for the chronic need of transfusions and for the impairment of the immunological functions.

1160 stool specimens, from 160 severely immunocompromised patients, from 70 adults and 180 children with acute diarrhoea and from 60 controls without diarrhoea and without evidence of immunocompromising underlying disorders, were examined for Cryptosporidium excretion. Only two children (1.1%) (one with previous contact to a straying cat and to lambs, the other without known risk) had documented intestinal cryptosporidiosis, whereas none of the symptomatic adults, immunocompromised patients or controls were found to be positive for Cryptosporidium fecal excretion. Other potential protozoal enteric pathogens among immunocompromised patients were only found in seven of 25 patients with HIV infection. We conclude that sporadic intestinal cryptosporidiosis in Southern Germany is a rare disease in humans even of younger age, but should be included in the differential diagnosis of diarrhoea in immunocompetent and immunocompromised patients.

We undertook a study over a period of 9 months to define the frequency of parasitic infections in hospitalized children with diarrhoea between the ages of 15 months and 5 years. Every alternate day, mothers of all children admitted with diarrhoea between 09.00 hours and 12.00 hours to one of the wards of the Department of Pediatrics and Child Health of the University Teaching Hospital (UTH) in Lusaka, Zambia, were interviewed for enrollment of their children into the study. A total of 178 children with diarrhoea were enrolled in the study. Of these 44 (25 per cent) were HIV seropositive and 134 (75 per cent) were seronegative for HIV. Out of 44 HIV-seropositive patients, 20 (45 per cent) had acute diarrhoea and 24 (55 per cent) had chronic diarrhoea. Of the 134 HIV-seronegative patients, 68 had acute diarrhoea (51 per cent) and 66 (49 per cent) had chronic diarrhoea. At least one intestinal parasite was found in 34 out of the 178 children enrolled. The commonest parasites identified were Ascaris and Cryptosporidia. No associations were identified between parasite isolation and the following: age, sex, or socio-economic status. Cryptosporidium spp. was isolated from 6 out of 44 (14 per cent) HIV-seropositive children, while 8 out of 134 (6 per cent) seronegative children had the parasite (P = 0.01). HIV-seropositive children with chronic diarrhoea had significantly higher cryptosporidium identification rates than those HIV-seropositive children with acute diarrhoea [5 out of 24 (21 per cent) patients with chronic diarrhoea compared to 1 out of 20 (5 per cent) patients with acute diarrhoea; (P > or = 0.01)].(ABSTRACT TRUNCATED AT 250 WORDS)

Over a period of 9 months (June 1, 1992-February 25, 1993), a total of 287 patients with diarrhea presenting at the adult medicine filter clinic (130) and the dermatovenereology clinic (157) of the University Teaching Hospital in Lusaka, Zambia, were enrolled in a study of the frequency of parasitic infections in adults with diarrhea. All of the 157 patients recruited from the dermatovenereology clinic were HIV-seropositive. Of these, 97 (62%) had chronic diarrhea; 7 (4%) had acute diarrhea, and 53 (34%) had no diarrhea. Out of 130 patients recruited from the adult medicine filter clinic, 85 (65.4%) were HIV-seropositive and 45 (34.6%) were seronegative. Of the HIV-seropositive patients, 58 (68%) had acute diarrhea and 27 (32%) had chronic diarrhea. 10 (23%) of the HIV-seronegative patients had chronic diarrhea. The common parasites detected in stools of all HIV-seropositive adults were Ascaris lumbricoides, hookworm, Entamoeba coli, and Cryptosporidium spp. The coccidian parasites Isospora belli and Cryptosporidium spp were seen only in the HIV-seropositive group. In the dermatovenereology clinic there was a statistically significant difference between parasite detection rate of Isospora belli and Cryptosporidium spp in HIV-seropositive patients with chronic diarrhea compared to asymptomatic HIV-seropositive individuals (p = 0.01 and p 0.05, respectively). Cryptosporidium was detected in 4 (4.7%) HIV-seropositive adults in the adult medicine filter clinic and in 4 (4%) seropositive patients with diarrhea in the dermatovenereology clinic. Isospora belli was detected in 5 (6%) HIV-seropositive adult medicine filter clinic patients, while 9 (9%) HIV-seropositive patients from the dermatovenereology clinic had this parasite. A significant difference in detection rates of Entamoeba coli was seen between the HIV-seropositive group in the dermatovenereology clinic: 17 (10.8%), compared to patients in the adult medicine filter clinic: 1 (1.5%).

The authors report the case of a 45-year-old HIV and HTLV1 antibody positive male patient form French West-Indies who was infected by disseminated histoplasmosis presenting as acute diarrhea. Esophagogastroduodenoscopy revealed gastric mass and colonoscopy patchy erythematous mucosa. The diagnosis was made by histology of bone marrow specimens, upper gastrointestinal tract and colon biopsies, and late skin lesions. Initial therapy with amphotericin B and itraconazole was successful, but maintenance therapy with itraconazole alone did not prevent relapse and a fatal outcome. Disseminated histoplasmosis in AIDS patients may be present as gastrointestinal manifestations and should be kept in mind in non endemic areas such as the French West Indies.
