The frequency of the opportunistic infections of the duodenum in AIDS patients was determined by way of histologic study in 207 patients between January 1987 and June 1991. All cases had serial paraffin sections, run through HES, PAS, Giemsa, Brown-Brenn, and Zieh-Neelsen stains, and 20 cases had in addition cytologic and electron microscopic study. 63 patients had opportunistic infections (10 cryptosporidiosis and 2 isosporiasis; 12 mycobacterial enteritis; 15 CMV enteritis; 7 candidosis; 7 intestinal microsporidiosis confirmed by electron microscopic examination; 12 Giardiasis; 3 duodenal leishmaniasis; 1 intestinal cryptococcosis). Multiple concurrent infections were noted in 6 cases. A mild to severe villous atrophy was observed in 28 cases, associated with opportunistic infection. A patchy distribution of pathogen agent was noted in 34 cases, and 37 cases were associated with oesophagal candidosis. This study points out the value of histologic examination of intestinal biopsy for the diagnosis of systemic infections as well as of unusual parasitosis, and the necessity for multiple endoscopic biopsies because of the frequent patchy distribution of pathogens.

Cryptococcosis is an epidemiological and immunological indicator due to the absence of Cryptococcus neoformans as a saprophyte in immunocompetent humans and the advantage of specific C. neoformans culture. On this basis, a report is presented on the CD4 lymphocyte count of 36 AIDS patients suffering from cryptococcosis and other concomitant or missing opportunistic AIDS-defining infections. In 26 out of 36 patients, i.e. 72%, a CD4 lymphocyte count of < or = 50/microL (mean value 39.5%) was found. Cryptococcosis as the sole opportunistic infection was diagnosed in 5 cases (13.9%). In 31 cases, various combinations of AIDS-associated diseases were found: Pneumocystis carinii pneumonia (PCP) (n = 19), cytomegalovirus infection (CMV) (n = 10), Kaposi's sarcoma (n = 6), Mycobacterium avium intracellulare infection (MAI) (n = 5), pneumonia (n = 2), toxoplasmosis (n = 2), Candida esophagitis (n = 1), tuberculosis (n = 1), lambliasis (n = 1), salmonellosis (n = 1) and wasting syndrome (n = 5). The conspicuous simultaneous occurrence or succession of pneumocystosis and cryptococcosis and the contrasting absence of aspergillosis and mucormycosis (zygomycosis) are commented. Based on the present observations in HIV-infected persons in Berlin, a CD4 lymphocyte count of < 150/microL may be used as a parameter indicating a predisposition for cryptococcosis as an airborne AIDS-defining infection. Attention is drawn to bird droppings as the sole habitat of C. neoformans and accidental niche of various other microorganisms.

Human immunodeficiency virus (HIV)-associated immune reconstitution inflammatory syndrome has been reported in association with tuberculosis, herpes zoster (shingles), Cryptococcus neoformans, Kaposi's sarcoma, Pneumocystis pneumonia, hepatitis B virus, hepatitis C virus, herpes simplex virus, Histoplasma capsulatum, human papillomavirus, and Cytomegalovirus. However, it has never been documented with giardiasis. We present a 7-year-old HIV infected girl who developed diarrhea and shock following the initiation of antiretroviral therapy, and her stool showed the presence of giardiasis.
