As part of the Hemophilia Growth and Development Study, we investigated the impact of human immunodeficiency virus (HIV) infection on statural growth, weight gain, and skeletal and sexual maturity in more than 300 boys with moderate to severe hemophilia, of whom 62% were infected with HIV. Age-adjusted height and weight were reduced in the HIV-infected subjects (p < 0.001). However, mean weight for height and triceps skin-fold thickness of the infected-boys closely resembled those of the uninfected group. In HIV-infected boys, height for age was positively related to the CD4+ lymphocyte count when the count was < 200 cells/mm3. Age-adjusted serum testosterone levels did not differ by HIV status, but in the infected participants the mean age-adjusted bone age was significantly reduced (p = 0.038) and the distribution of Tanner stages, adjusted for age, differed significantly (p = 0.003). The probability of advancing one or more Tanner stages in the first study year was significantly slowed in HIV-infected boys more than 14 years of age (p = 0.0003). We conclude that linear growth was significantly impaired in boys with hemophilia and HIV infection, but the wasting of malnutrition was not found. The delays in bone age and pubertal maturation strongly suggest that part of the growth failure seen in acquired immunodeficiency syndrome can be attributed to pubertal delay. We speculate that the lack of demonstrable difference in age-adjusted testosterone concentrations might reflect subtle differences in the pattern of secretion of testosterone or in the concentration of sex-hormone binding globulin.

Infection due to the Mycobacterium avium complex (MAC) is the most common opportunistic disease of bacterial origin among patients with AIDS in the United States. The incidence of disseminated disease due to MAC (DMAC) has risen dramatically in recent years. The risk of developing DMAC increases as the CD4+ lymphocyte count declines to < 100/mm3. Preliminary analyses of several studies suggest that gender, racial or ethnic group, and individual risk factors for human immunodeficiency virus infection do not influence the incidence of DMAC but that prior Pneumocystis carinii pneumonia, the development of severe anemia, or the interruption of antiretroviral therapy may increase risk. Both the respiratory and the gastrointestinal tracts probably serve as portals of entry for MAC. Colonization may potentiate the risk of DMAC but does not always precede dissemination. Patients with AIDS and DMAC have a shorter duration of survival than do those with AIDS but without DMAC. While treatment for DMAC may extend survival, no well-controlled, prospective, randomized clinical trial has documented this point. Most patients with AIDS and DMAC have disseminated multiorgan disease; the most frequently described symptoms include fever, night sweats, weight loss or wasting, diarrhea, and abdominal pain. The most commonly identified laboratory abnormalities are anemia and elevated serum levels of alkaline phosphatase. Localized disease syndromes related to MAC infection occur less often.

The HIV wasting syndrome and other HIV-associated weight loss is a major problem in HIV-infected patients. The available data strongly suggest that wasting is associated with decreased survival. It may also further impair immune function. A variety of etiologies probably contribute to this wasting, including hypermetabolism, alterations in metabolism, lessened oral intake, malabsorption, cytokine effects, and endocrine dysfunction. The relative contributions of each of these etiologies to wasting probably varies considerably from patient to patient. Successful treatment calls for identification of possible etiologies of wasting in the individual patient with AIDS. Further treatment may include treating underlying conditions and controlling such symptoms as diarrhea, nausea, or fever. Nutritional support, including both parenteral and enteral nutrition, has shown some promise of efficacy, and a variety of drugs appears to be helpful. Future treatment to reverse wasting may include the use of several of these agents in combination. Currently, there is much that clinicians can do to evaluate and treat the HIV wasting syndrome, with significant potential benefits to their patients.

During July-October 1989 in Zaire, a physician examined and took blood and stool samples from 198 adult patients at Mama Yemo Hospital in central Kinshasa to learn the prevalence of enteric viruses and their link to diarrhea, immunosuppression, and wasting among HIV infected and uninfected patients. In Kinshasa, diarrhea is prevalent and heterosexual intercourse is the main mode of HIV transmission. 57.6% of the patients were infected with HIV. 50% of the HIV-positive patients had AIDS. 93% of all HIV-positive patients either had AIDS (stage IV) or advanced stage III disease. 49% of them died while in the hospital. 22% of the HIV-negative patients died while in the hospital. 17% of all adult patients studied were infected with at least 1 enteric virus, especially rotavirus. Enteric viruses were isolated from both HIV infected and uninfected patients (17% and 18%, respectively). State of immunocompromise did not significantly affect viral shedding, but fewer patients in the less immunocompromised stages shed viruses than did those in the advanced stages of immunocompromise (3 vs. 72 patients). When examining the ratio of circulating CD4 and CD8 T cells in HIV-infected patients, however, there was a trend toward greater frequency of enteric viruses (p = .07). Chronic diarrhea was significantly associated with HIV seropositivity (p 0.01), HIV stage (p .001), and CD4/CD8 T cell ratio (p .01). Acute diarrhea was not associated with any of the above, however. These findings suggest that enteric viruses were not a significant cause of diarrhea, but they were isolated somewhat more often in patients of advanced immunosuppression.

In the past several years, microsporidia have become recognized as another important group of opportunistic infections of immunocompromised patients, especially those with AIDS. Enteric infections with the noncultivatable microsporidian parasite Enterocytozoon bieneusi have been diagnosed from AIDS patients with chronic diarrhea, malabsorption, and wasting. The incidence of infection and mechanism of transmission of these organisms in humans is unknown. Several recent tests for human pathogens have been developed using rRNA genes as diagnostic probes. Using the polymerase chain reaction and conserved regions of the small subunit rRNA (SSU-rRNA) gene, the SSU-rRNA gene of E. bieneusi was successfully cloned and subsequently sequenced. Amplification of E. bieneusi rRNA could be demonstrated from intestinal biopsies from HIV-1-infected patients infected with E. bieneusi but not from intestinal biopsies from noninfected patients. This cloned SSU-rRNA gene was used to develop improved probes for detection of E. bieneusi in tissue of infected patients.

We compared endocrine function in patients with the HIV wasting syndrome with other HIV-positive patients without wasting to determine associations between endocrine dysfunction and wasting. Sixty-six HIV-seropositive patients were evaluated by thyroid, gonadal, and adrenal function tests. Fourteen of these patients met the clinical definition of wasting. Total and free testosterone levels were significantly lower in patients with wasting compared with patients without wasting with both similar and higher mean CD4 counts. Prolactin levels were significantly higher, and cortisol levels were higher with borderline significance in patients with wasting compared with patients with similar CD4 counts without wasting. These findings suggest that endocrine function in the HIV wasting syndrome differs from that of HIV-infected patients without wasting, which may have implications about the pathogenesis and treatment of the HIV wasting syndrome.

Fungal infections account for a large number of AIDS-index diagnoses and complicate the course of most patients with HIV disease. Infection with Cryptococcus neoformans is the most commonly encountered deep-seated fungal infection in AIDS and represents a major threat to HIV-infected people worldwide. Although most patients with cryptococcosis present with meningitis, pulmonary disease may occasionally dominate the clinical picture. Treatment of symptomatic pulmonary cryptococcosis remains amphotericin-B with or without 5-flucytosine. The toxicity and difficulty of administration of amphotericin-B has engendered interest in treatment alternatives with the new triazoles. As HIV infection has become more common in the American heartland, it has overlapped areas endemic for Histoplasma capsulatum, Coccidioides immitis, and Blastomycosis dermatitidis. Disease from these deep-seated fungal pathogens, whether from de novo exposure or reactivation, has protean manifestations. Common to all is a protracted, febrile, wasting illness, with or without respiratory symptoms. Treatment of choice for all these infections remains amphotericin-B, followed by lifelong-maintenance therapy with a triazole. In this article I review the microbiology, epidemiology, presentation, diagnosis, and treatment of AIDS-associated deep-seated fungal infections.

Manyemen, a rural community in Cameroon, has now been hit by the HIV epidemic. This paper describes the experiences gained at the Presbyterian General Hospital in Manyemen between 1990 and 1992 regarding HIV infection in pregnant women, AIDS case management, counseling and home visits. A total of 383 pregnant women attending antenatal clinics were tested. We found a 2.9% HIV-1 seroprevalence and a 17% reactivity to a non-specific syphilis test, rapid plasma reagin, RPR. In 1990, 1991 and 1992, we diagnosed 55, 89 and 94 cases of clinical AIDS respectively. New TB cases seen in the same period showed the following HIV positive rates 3.5%, 2.4% and 5.8%. A detailed study of 78 AIDS patients revealed that the five most common presenting signs in our patients were wasting (80%), prolonged fever (28%), chronic diarrhoea (17%), oropharyngeal candidiasis (14%) and pulmonary TB (10%). Pretest and post test counseling is routinely done by the AIDS team. About 79% of the patients were post counselled as were 27% of their relatives. Home visits have been started. These results show that AIDS is no longer an issue confined to cities in Cameroon and that rural hospitals should institute a programme, similar to ours, to help them cope with the AIDS epidemic.

The relation of small intestinal dysfunction and malnutrition (body composition and serum index parameters of nutrition) was investigated in 36 male patients with AIDS. Mucosal absorptive capacity was assessed by the 25 g D-xylose test. D-xylose absorption (2 h - serum profile and 5 h - urine) classified 17 patients as having impaired and 19 patients as having normal absorption. In both groups body weight, body mass index as well as body composition analysis indicated malnutrition when compared to healthy male controls (n = 340) or asymptomatic HIV-infected patients (n = 26). Patients with abnormal D-xylose test had more severe malnutrition indicated by a lower body cell mass (17.7 +/- 5.4 vs. 22.5 +/- 4.5 kg; p < 0.01) and an increased ratio of extracellular mass to body cell mass (1.99 +/- 0.82 vs. 1.45 +/- 0.46 p < 0.01). Total serum protein, albumin, cholinesterase activity, cholesterol and LDL were significantly diminished in AIDS-patients with abnormal D-xylose test compared to those with normal D-xylose absorption. Intestinal dysfunction indicated by decreased D-xylose Intestinal dysfunction indicated by decreased D-xylose absorption thus represents an important feature of malnutrition and wasting, and patients with abnormal D-xylose absorption have more profound impairment of body composition, visceral proteins and lipids reflecting malnutrition than patients with unaffected intestinal absorption.

Human immunodeficiency virus type 1 (HIV-1) is frequently associated with weakness and muscle wasting, referred to as HIV-1 wasting myopathy. This illness, often observed in the advanced stages of acquired immunodeficiency syndrome (AIDS), responds poorly to therapeutic intervention. We describe the cases of three AIDS patients with HIV-1 wasting myopathy who had a favorable response to anabolic steroids as evidenced by an improvement in strength, muscle bulk, body weight, and sense of well-being.
