This article presents electronmicroscopy evidence of retrovirus-like particles with bar shaped cores in salivary and prostate glands as well as testicles of 2 acquired immunodeficiency syndrome (AIDS) patients. The 1st case, a 38-year old black male homosexual, presented in 1982 with diarrhea, malabsorption, and weight loss. In the following 1 1/2 years, he experienced recurrent Candida esophagitis, cutaneous and pulmonary Kaposi's sarcoma, Pneumocystis carinii pneumonia, and cytomegalovirus. Autopsy in 1984 revealed residual Kaposi's sarcoma, disseminated cytomegalovirus, and M avium-intracellulare. The 2nd case, a 31-year old white male homosexual, presented in 1984 with Pneumocystis carinii penumonia and subsequently developed persistent fever, hepatomegaly, headaches, blurred vision, progressive liver function deterioration, and disseminated histoplasmosis infection. Autopsy in 1984 revealed an overwhelming disseminated histoplasmosis infection. Tissues taken at postmortem were examined by electron microscopy. Particles that conformed with the morphologic characteristics of AIDS retrovirus (a size of about 140 nm, a round shape with a double membrane, and an elongated core) were detected in the prostate gland of patient 2 and in the salivary glands and testes of both patients. This finding suggests that saliva and semen may be body fluids by which transmission of the AIDS virus occurs.

This report describes the clinical spectrum and outcome of the hemophagocytic syndrome (HS) in 5 HIV infected patients. All 5 patients presented with fever, hepatomegaly and/or splenomegaly, confusion or coma and respiratory symptoms. Severe anemia was associated with thrombocytopenia and with neutropenia in 4 cases. Diffuse intravascular coagulopathy was present in 2 cases. Liver function tests were abnormal in three patients. The diagnosis of HS was made 2 to 12 weeks after the onset of symptoms and required in most patients repeated examinations of the bone-marrow, showing infiltration by histiocytes with prominent phagocytosis of blood cells. In one case this infiltration was not seen in the bone-marrow but only in the liver and the spleen. Varicella, mycobacterium infection, oesophageal candidiasis, Kaposi sarcoma were observed in the evolution of 3 patients. Anaplastic large cell Ki-1 lymphoma was present in one case. Four patients died as a result of complications of HS. The one patient with lymphoma survived.

HIV is a very common infection in Thailand, affecting about one million of the population already, with 99,555 persons with full blown AIDS at the end of 1999. The first case of AIDS was reported in Thailand in 1984. Gastrointestinal involvement is very common, the commonest presentations are diarrhea, esophageal symptoms, hepatobiliary symptoms, and weight loss. When the CD4+ T cell count falls below 200, the body becomes highly susceptible to opportunistic infections and neoplasms. Almost all AIDS patients will have GI symptoms at sometime during the course of their illness. This is because the GI tract contains an abundant quantity of lymphoid tissue and is likely to function as a reservoir of HIV infection. In chronic diarrhea cases, apart from other investigations, small bowel biopsy and aspiration may help to find the cause. If oral candidiasis is present, one should keep HIV in mind and look for oral hairy leucoplakia, dysphagia and odynophagia as one-third of patients with AIDS will develop dysphagia or odynophagia in the course of their disease. Those with esophageal candidiasis will usually have oral candidiasis and odynophagia while 18 per cent of the patients will not have oral thrush. CMV esophagitis and HIV ulcer (or idiopathic oesophageal ulcer) are also common. Upper gastrointestinal endoscopy and biopsy are helpful in finding the exact cause of the oesophageal symptoms. Hepatobiliary manifestations are present with jaundice, hepatomegaly, and pain. ERCP is very helpful in diagnosing and classifying these conditions. Papillary stenosis and dominant biliary stricture can be treated by endoscopy but long term results are still poor due to late manifestation of these conditions.
