An interesting temporal relationship exists between the emergence of the epidemic of intestinal parasites in the homosexual male population and the subsequent appearance of Kaposi's sarcoma. Existent models suggest possible links between chronic parasitosis, viral infection, and the emergence of malignant disease. Patients with AIDS-related conditions have been demonstrated to have a high rate of asymptomatic amebiasis. Possible links between intestinal parasites and the development of Kaposi's sarcoma in human immunodeficiency virus-infected patients are explored.

In Los Angeles County from 1983-1988, rates of amebiasis declined 65 percent among White males 15-44 years. No such decline occurred among White females 15-44 years or White males less than 15. Reported acquired immunodeficiency syndrome (AIDS) cases in the district of highest AIDS incidence has followed the initial decline in amebiasis by four years. Amebiasis trends may be a useful predictor of human immunodeficiency virus (HIV) transmission and future rates of AIDS among gay men.

Among homosexual men the prevalence of infection with Entamoeba histolytica is high. To determine the clinical importance of this infection 55 homosexual men carrying the parasite were investigated in detail. No clinical, serological, or histological evidence of invasive amoebiasis was found in any of them. The patients were not treated and were followed up for 12 to 29 months (mean 21.6 months), during which period none developed symptoms that could be attributed to E histolytica. Spontaneous loss of the parasite occurred in 17 patients, some of whom later became reinfected. Sixteen patients had antibody to human immunodeficiency virus, and infection with E histolytica showed the same benign course in them as in the patients who did not have antibody. Throughout the study classification of the isolates of E histolytica consistently showed that they belonged only to non-pathogenic zymodemes. The findings provide further evidence that E histolytica in homosexual men is a commensal organism.

The authors describe their experience of the infection by the virus of the human immunodeficiency HIV-1 in Burundi. The acquired immunodeficiency syndrome was brought to light in 1983 by the emergence of cryptococcal meningitis, Kaposi's sarcomas, disseminated candidiasis. 109 cases of infection by the virus of the human immunodeficiency (HIV) AIDS related complex, or acquired immunodeficiency syndromes, were observed in 8 months and are related in this paper. The authors elucidate the spread and amplify the role played by lorry drivers. The frequency of recent case history: tuberculosis, zona, sexually transmitted diseases (41%). Clinical manifestations have been studied according to their clinical stage: 28 patients are AIDS related complex (25%), 81 are acquired immunodeficiency syndrome. One have to notice the frequency of tuberculosis at the stage of acquired immunodeficiency syndrome, of digestive parasitoses, not only coccidiosis, but also strongyloidiasis and colonic amoebiasis, cryptococcal meningitis, and encephalopathies caused by the virus of human immunodeficiency (HIV) at the period of AIDS. Lethal evolution is fast: 28 out of the 81 AIDS were observed up to their end, occurring in less than 60 days, as an average. Lastly, numerous opportunistic infections cannot be diagnosed because the lack of technical facilities.

A 26-year old female developed acute fulminant amoebic colitis during the post-partum period, successfully managed by subtotal colonic resection without anastomosis. Fulminant transmural amoebic colitis is a rare life-threatening complication of invasive bowel amebiasis. Pregnancy, delivery, diabetes mellitus and immunodeficiency are the main risk factors. At pathologic examination, bowel wall necrosis can be seen with amoebae present in the lumen of capillary vessels. The diagnosis of amoebic colonic perforation is difficult, especially in a non-endemic area. Conservative surgical management is required in non-perforated forms. If perforated, the bowel must be resected, limited to macroscopic lesions.

Protozoan infections represent an area of concern for advanced practice nurses, particularly those working in rural areas or urban environments with refugee populations and those caring for patients with immunodeficiency-related diseases. Some of these infections have major effects on the fetus and neonate yet pose minimal problems to the mother. Protozoan infections are increasing in prevalence because of poor sanitation, overcrowding, increased foreign travel, and high-risk sexual behaviors. There is a need for public education to promote awareness and prevention of such infections. This emerging public health problem has been reported sporadically in the medical and perinatal nursing literature. This paucity of information may be partly due to the difficulty in diagnosing and managing these infections in the perinatal patient. The article discusses the more common infections caused by protozoa, amebae, and sporozoa: trichomoniasis, giardiasis, amebiasis, and toxoplasmosis.

Homosexual persons or human immunodeficiency virus (HIV)-infected patients frequently excrete cysts of nonpathogenic strains of Entamoeba histolytica ("Entamoeba dispar"). However, invasive amoebiasis is rare. We report two patients with AIDS and cytomegalovirus colitis in whom invasive amoebiasis was histologically diagnosed. It is concluded that E. histolytica has to be considered in HIV-infected patients with colitis.

Admitted medical records, from January 1988 to December 1995, of 28 symptomatic amebic patients who lived in the east-southeast area of Tokyo were studied retrospectively, in order to find the present characteristics of symptomatic amebiasis due to Entamoeba histolytica in this area. Categorized by disease, there were 14 cases of colitis, 9 cases of liver abscess, 4 cases of colitis with liver abscess, and 1 case of liver abscess with brain abscess. Patients consisted of 26 Japanese males, 0 Japanese females, 1 non-Japanese male and 1 non-Japanese female. The mean age of colitis patients and liver abscess patients was 55.4 years old and 41.3 years old, respectively. The presumed place of contraction was Japan in 64% of the patients. Forty-eight percent of male patients indicated that they engaged in homosexual or bisexual practices, and 36% of male patients who denied such sexual practices or did not answer the question had no history of marriage. Positive rate of serum titre for Treponema pallidum hemagglutination test (TPHA) and human immunodeficiency virus antibody was 42.9% and 0%, respectively. Sixty-seven percent of TPHA-positive patients indicated that they engaged in male homosexual or bisexual practices. Zymodeme patterns of E. histolytica isolated from 4 colitis patients were XIV in 1 case and II in 3 cases. Symptomatic amebiasis in the east-southeast area of Tokyo is a disease which predominantly afflicts males, especially those in their middle age, and most patients contract the disease in Japan. The high rates of patients who engaged in male homosexual or bisexual practices and the high rates of patients with positive TPHA suggest that amebiasis is likely to be sexually transmitted disease in homosexual and bisexual men in the east-southeast area of Tokyo, and zymodeme II may be the predominant type in symptomatic amebic colitis in this area.

During the course of systemic infections, the liver is an organ which is frequently involved. The pathology of the human immunodeficiency virus with all its infections, opportunistic tumours and some parasitoses, such as amebiasis, kala-azar, hydatidosis, schistosomiasis and fascioliasis, evolve into hepatic compromise. This development is what we attempt to summarise.

Invasive amebiasis rarely occurs in homosexual men and human immunodeficiency virus (HIV)-infected individuals and has not been regarded as a beacon for concomitant HIV infection. We encountered a bisexual man with a protracted course of amebic liver abscess and amebic colitis. In the presence of fever, generalized lymphadenopathy, and elevated serum aminotransferase levels, HIV infection was suspected and then confirmed by a de novo seroconversion of HIV antibody. Subsequently, we noted two consecutive patients with amebic liver abscess, also later found to be infected with HIV. The ameba obtained from these three cases was identified as Entamoeba histolytica by amplification of 16S ribosomal RNA by polymerase chain reaction and direct sequencing. This observation suggests that amebic liver abscess and colitis can be presentations for HIV infection in the Far East. Thus, the local patients with invasive amebiasis, especially those with a protracted course or with risk factors of HIV infection, should be tested for HIV.
