Physicians examined the records of 47 adults with visceral leishmaniasis (VL) and HIV-1 infection who were patients at 3 urban teaching hospitals in the Andalucia region in southern Spain between January 1986 and November 1991. They wanted to identify the clinical, biological, and epidemiological features of VL in HIV-1 positive patients. 96% of the cases were diagnosed with both infections during the last 2 years of the study period and 79% between January and November 1991. All the patients had risk factors for HIV infection (65.9% IV drug use, 21.3% sexual contact, and 12.8% blood transfusion). 70% exhibited the classic symptoms of VL (fever, enlarged liver and spleen, and depressed counts of blood cells). Most patients were already very immunocompromised when VL was diagnosed. 87% had a total lymphocyte count of less than 1000 x 1 million/1 and a CD4 lymphocyte count of less than 200 x 1 million/1. In fact, 66% had full blown AIDS prior to diagnosis of VL. VL was the first severe infection in 10 cases. 68% also suffered from opportunistic infections, especially candidiasis, extrapulmonary tuberculosis, and Pneumocystis carinii pneumonia. Microscopic examination of Leishmania amastiogotes in tissue samples led to a diagnosis in 94% of cases, isolation of motile amastigotes in culture of bone marrow aspirate in 2%, and microscopic and culture in 4%. Just 46% completed a full course of treatment (pentavalent antimony, allopurinol, and/or pentamidine). Only 38% had a microbiological response. Immunofluorescence detected sizeable titers (1:40) of antileishmanial antibodies in just 31% of cases. 17% experienced clear clinical improvement. Physicians in endemic areas should consider VL in every HIV-1 infected patient with fever, hepatosplenomegaly, or hematological abnormalities to avoid underdiagnosis of leishmaniasis.

A 37-year-old black man with presumed Pneumocystis carinii pneumonia who was treated with systemic IV pentamidine had fatal pancreatitis and massive hepatomegaly. Fatal pancreatitis can occur with no hemorrhagic changes seen at autopsy. Awareness of the relationship between pentamidine and pancreatitis should be emphasized. With current clinical trials testing other routes of administration, fatal complications associated with IV pentamidine therapy will be minimized.

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.

We report here nine children with AIDS. The risk factors of these patients were hemophilia in one, blood transfusions in four, maternal intravenous drug use in three and paternal AIDS in one. One baby was also of Haitian parentage. The major clinical symptoms included failure to thrive, hepatomegaly, lymphadenopathy, interstitial pneumonia, recurrent bacterial and viral infections and persistent oral thrush. Three infants had chronic recurrent parotitis. Five infants developed opportunistic infections primarily Pneumocystis carinii pneumonia and all five died of bacterial sepsis. None of the infants were lymphopenic but all had reversed T4/T8 ratios and poor in vitro lymphocyte responses to pokeweed mitogens. Although many of the clinical and laboratory features of pediatric and adult AIDS are similar, there are some unique features for pediatric AIDS such as the absence of lymphopenia and the high prevalence of recurrent bacterial infections and sepsis.

From Oct 1, 1982, to Oct 1, 1983, the Centers for Disease Control (CDC) received reports of 35 children whose illness met the CDC definition of acquired immune deficiency syndrome (AIDS). All of the children had serious opportunistic infections without a known underlying illness to explain susceptibility to the infections. The 35 children were residents of ten different states; cases clustered in five major metropolitan areas. Three of the children had a parent with AIDS, and one child who had been previously reported had received a blood transfusion from a person in whom AIDS later developed. Most of the children had at least one parent in a population group in which adult AIDS cases have occurred. Many of the children had histories of prodromal symptoms, including pneumonitis, lymphadenopathy, hepatomegaly, and oral thrush. The mean age at onset of illness was 5 months, and the mean age at diagnosis was 12 months. To determine whether opportunistic infection in children without underlying immunodeficiency was truly a new phenomenon, a review of requests to the CDC for the drug pentamidine isethionate was undertaken. This revealed an apparent increase from 1979 to 1983 in Pneumocystis carinii pneumonia in children without known underlying immunodeficiency.

Prenatal diagnosis of maternal diseases common to HIV infection may alert the clinician to potential HIV infection in the infant, with resultant early diagnosis and treatment. Although of limited value in the first months of life, imaging studies can be beneficial in selected cases and may be the first clue to the diagnosis of AIDS. The multisystem involvement frequently seen in AIDS necessitates multiple imaging modalities. Recurrent pneumonia, particularly Pneumocystis carinii pneumonia, may be first suggested by the chest radiograph. Brain atrophy and white matter disease, shown on MR imaging or CT early in life, can suggest AIDS. Ultrasonography is not only crucial for prenatal fetal assessment, but it also is important for evaluation of the common findings of hepatomegaly, adenopathy, and tumors, as well as inflammatory fluid collections.

A follow-up study of 179 cases of human immunodeficiency virus (HIV) seropositive neonates born from HIV seropositive mothers is reported. At the time of the present study, HIV infection resulting from maternofetal transmission was found in 50 cases, while 108 infants were not infected; HIV infection remained uncertain in 16 cases; 5 infants were lost for follow-up. Out of the 50 infected cases, 20 were less than two-year old, 17 were 2-5 year old and 13 were older than 5 years. Very few remained asymptomatic after the age of 6 months, the most common symptoms being adenopathies and/or hepatomegaly and/or splenomegaly. Twenty-six had an acquired immunodeficiency syndrome (AIDS). Six died, from pneumocystosis (3), cytomegalovirus infection (1) and septicemia (2). Virus culture and polymerase chain reaction were the most efficient laboratory methods for early diagnosis of HIV infection, both being positive in more than 95% of the infected cases after the age of 3 months. A close clinical and biological supervision is recommended in these infants and children because of the permanent threat of infectious diseases in relation to their immunodeficiency. Treatment associates: 1) antiviral therapy with AZT as soon as the HIV infection is diagnosed; 2) primary prophylaxis against pneumocystosis with trimethoprim-sulfamethoxazol; 3) IV immunoglobulins in the case of repeated bacterial infection; 4) regular evaluation of the nutritional status and psychological assistance.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical and epidemiologic characteristics of the acquired immunodeficiency syndrome (AIDS) were studied in a tropical area of Brazil. During an 18-month period (July 1989-January 1991), 111 consecutive AIDS patients (102 men and nine women) were evaluated. Patients reported homosexual/bisexual activities (60%), intravenous drug use (19%), or both (6%), heterosexual activities (11%), blood transfusions (2%), and 2% belonged to an undetermined category. Weight loss, fever, oral thrush, and diarrhea were present in > or = 70% of the patients at presentation. An unexpected high frequency of hepatomegaly (49%) was detected, and found to be significantly associated with tuberculosis (P < 0.0001). Although the epidemiologic features of human immunodeficiency virus transmission were comparable to the United States/European pattern, the clinical spectrum of opportunistic infections more closely resembled that reported in Africa and Haiti, with a greater frequency of fungal and mycobacterial infections than Pneumocystis carinii pneumonia and viral infections.

The scarcity of reported cases of paracoccidioidomycosis and AIDS remains unexplained. We review the details of the 27 cases reported in the medical literature. Paracoccidioidomycosis occurs in patients with advanced AIDS who are not receiving prophylaxis for Pneumocystis carinii pneumonia with trimethoprim-sulfamethoxazole, which is also effective against Paracoccidioides brasiliensis. Clinical manifestations include prolonged fever, weight loss, generalized lymphadenopathy, splenomegaly, hepatomegaly, and skin rash. Diagnosis can often be made by direct microscopic examination and culture of the fungus from skin and lymph node specimens and occasionally from sputum, blood, spinal fluid, and bone marrow specimens. Since antibodies to P. brasiliensis are occasionally detected, the diagnosis should not be ruled out for patients whose serology is negative. Despite specific therapy with different regimens, the overall mortality of paracoccidioidomycosis among patients with AIDS is high (30%). The prognosis can be improved by earlier diagnosis and aggressive therapy with amphotericin B, followed by lifelong immunosuppressive therapy with trimethoprim-sulfamethoxazole. Health care providers caring for human immunodeficiency virus-infected patients who live or have resided in areas in which paracoccidioidomycosis is endemic must be aware of the possibility that this systemic mycosis may occur and have potentially severe consequences.

At the end of 1984, there were about 1.5 million children worldwide infected with HIV-1. 75% of these children lived in sub-Saharan Africa and Latin America. The rate of mother-to-child transmission of HIV-1 is estimated to range from 13% to 42%. It is twice as high in Africa as it is in Europe. By the year 2000, 6 million pregnant women and 5-10 million children will be infected with HIV-1. It appears that clearance of HIV-1 infection occurs in 2.7% to 6.4% of infected infants. Possible intervention strategies to reduce perinatal HIV-1 transmission include antiretroviral therapy with zidovudine, recommending breast feeding only in areas where it is clearly necessary, cesarean section, passive immunotherapy with anti-HIV immunoglobulins, and viral envelope subunit vaccines. An accurate diagnosis of HIV-1 infection can occur in non-breast fed infants born to seropositive mothers by the age of 3 months. Most children (80-90%) with HIV-1 infection develop features of HIV-1 infection within the first year of life. Common manifestations in the first year are lymphadenopathy, splenomegaly, and/or hepatomegaly. Young infants, especially those 3-6 months old, are more likely to be diagnosed with Pneumocystis carinii pneumonia (PCP) than older HIV-1 infected children. HIV-1 infected children are more likely to develop PCP, serious bacterial infections, cytomegalovirus infection, lymphoid interstitial pneumonitis, and encephalopathy than adults. They are, however, less likely to develop other opportunistic infections (e.g., toxoplasmosis, tuberculosis, cryptococcoses, and histoplasmosis). Possible underlying mechanisms of disease progression in HIV-1 infected children include presence of rapidly replicating syncytium-inducing HIV-1, high virus burden, persistent neutralizing antibody response, antibody-dependent cellular cytotoxicity against HIV-1, and transplacental passage of maternal neutralizing antibodies.
