Investigations included 52 drug-addicts with asymptomatic HIV virus infection. 8 of them suffered some years ago, from virus hepatitis of type B. Physical examinations did not reveal in examined persons any deviations from normal condition except for hepatomegaly. Results of liver biochemical investigations remained within normal limits. In each of them one confirmed presence of serological markers of HBV infection and in 35 of them of HCV and in 5 of them in parallel HDV. In all the examined persons one carried out liver biopsy and routine morphological examinations. In every case one disclosed a liver injury of drug-induced type. Further, in 31 examined persons one detected a coexistence of chronic, active inflammatory process of liver hepatitis minimal--17 hepatitis chronica persistent--12 hepatitis chronica aggressivE--1 cirrhosis hepatis--1 and in four of them changes of the type fibrosis periportal. In HIV infected drug-addicts it comes about to clinically asymptomatic, chronic hepatitis coexisting with morphological changes of drug-induced type liver.

The signs that may arise after perinatal infection with human immunodeficiency virus type 1 (HIV-1) have been classified by the Centers for Disease Control, but the clinical usefulness of the classification system and the prognostic importance of each disease pattern have not been established. We sought to address these issues by analysing data from the Italian Register for HIV infection in children. We studied 1887 children born to HIV-1-seropositive mothers. 1045 were identified at birth and the others were registered later (median age 4.8 [range 0.4-72] months). HIV-1-associated signs developed in 433 (81.8%) of 529 seropositive infected children at a median age of 5 (0.03-84) months. These signs appeared significantly earlier in the 102 children who died of HIV-1-related illness than in those who are still alive (median 3 [0.03-55] vs 6 [0.03-84] months; p less than 0.001). The cumulative proportion surviving at age 9 years was 49.5% (95% confidence interval 27-65%) and the median survival time was 96.2 months. Separate analysis of the 112 seropositive infected children followed from birth and older than 15 months gave similar results. Hepatomegaly, splenomegaly, lymphadenopathy, parotitis, skin diseases, and recurrent respiratory tract infections formed the mildest disease pattern. Lymphoid interstitial pneumonitis and thrombocytopenia were signs of intermediate disease. By contrast, in multivariate analysis specific secondary infectious diseases, severe bacterial infections, progressive neurological disease, anaemia, and fever were significant and independent negative predictors of survival. Growth failure, persistent oral candidosis, hepatitis, and cardiopathy were associated in univariate analysis with significantly shorter survival. Our findings suggest that the outlook for children with perinatal HIV-1 infection is better than previously thought and that a new clinical staging system of single disease patterns is needed.

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.

The children of 50 women positive for antibody to human immunodeficiency virus type 1 (HIV-1) and 42 children of antibody-negative mothers were examined for lymphadenopathy and hepatosplenomegaly at 3-month intervals during the 1st year of life. Lymphadenopathy was found to be significantly more frequent at 6 months (p less than 0.01), 9 months (p less than 0.001) and 12 months (p less than 0.01) in children who were subsequently shown to be infected with HIV-1. Hepatomegaly was seen more frequently (p less than 0.05) in the 1st year in HIV-1-infected children than in uninfected children. Splenomegaly was not more frequent in HIV-1-infected children in this area which is holoendemic for falciparum malaria.

HIV is efficiently transmitted through transfusion with HIV-infected blood. Accordingly, 203 multitransfused children with thalassemia attending the thalassemia clinic of the Charak Palika Hospital in New Delhi were screened for antibodies to HIV using ELISA and Western blot tests. 8.37% of the sample tested HIV-seropositive (HIV+). These 17 children were joined by 3 others referred from a neighboring state to constitute a group to be matched against 20 HIV-children for the purpose of comparing psychosocial aspects. The control group was matched for age, sex, educational level, and socioeconomic status with mean age 10.8 years ranging over 1-16 years. 4 members of the HIV+ sample were diagnoses as having clinical AIDS according to WHO criteria. The remaining 14 boys and 2 girls were HIV+, but asymptomatic. 25% were of lower class, 63.5% middle class, and 12.5% upper class. Of those with AIDS, 50% were diagnosed in their first year of life and 82% were diagnosed by year 3. Symptoms generally developed after 4-6 months of life. Lymphadenopathy and hepatomegaly tend to be visible at birth, while chronic diarrhea, prolonged fever, oral thrush, recurrent bacterial infections, and hepatosplenomegaly may also be presented. 7.1% of cases aged 2-3 years exhibited rocking and head banging problems worse than did control subjects. Furthermore, 28.5% had temper tantrums and 21.5% ground teeth. These children may have delayed developmental milestones as well as behavioral problems. The small sample size, however, precludes concluding that psychosocial differences exist between those with HIV/AIDS and those with thalassemia major. In fact, behavioral problems in these children were due to child illness and not of HIV-positivity, for children tend to be unaware of HIV/AIDS infections and its consequences. The author recommends that HIV+ children continue to attend school unless they can not control bodily secretions, have uncoverable oozing lesions, have unacceptable behaviors, or if there is extreme possibility of contracting infectious diseases at school. The author also stresses parents' and families' need for long-term medical and psychological care.

By the end of 1990, 51 symptomatic children with perinatally acquired HIV infection had been admitted to Baragwanath Hospital. Of 42 children who were followed up for at least 3 months, 15 (35.7%) died and 16 (38.1%) were lost to follow-up. The case fatality rate for these children lies between 35.7% and 73.8%. Most children became symptomatic before the age of 6 months and presenting features seen in over 70% of cases included lymphadenopathy, failure to thrive and hepatomegaly. Surviving children had recurrent admissions to hospital, predominantly for respiratory distress. Many had bacterial pneumonias. Cardiac involvement (cardiomyopathy and cor pulmonale), recurrent serious bacterial infections and neurodevelopmental abnormalities were common. Our experience confirms that vertically acquired HIV infection has a relatively short incubation period and progresses rapidly with cardiorespiratory symptoms predominating. Five HIV seroprevalence studies have been conducted in pregnant women attending Baragwanath Hospital and the Soweto clinics since 1988. The calculated doubling time is between 7 and 21 months. At the end of 1990 the HIV seroprevalence rate in pregnant women was 0.82% (95% confidence limits 0.44-1.19%).

Reports mainly from Japan, recommend germanium (Ge)-containing compounds as "anti-cancer" and "immunostimulatory" remedies. We report on a 25-tear-old woman with stage II HIV disease who consumed a total of 47 g Ge as Ge-lactate-citrate 18%. She developed severe renal insufficiency (creatinine clearance 7 ml/min/1.73 m2, proteinuria 0.28 g/d) and hepatomegaly. Biopsies revealed tubulointerstitial nephropathy with vacuolar degeneration, mainly of distal tubular epithelia, and severe liver steatosis. Tissue Ge content in kidney and liver biopsy specimens was increased 68-and 140 fold respectively. In agreement with previous reports, renal dysfunction persisted 9 months later (creatinine clearance 11 ml/min/1.73 m2).

600 children born to HIV-infected mothers by June 15, 1990, in ten European centres were followed to study the natural history of HIV infection and the vertical transmission rate. They were seen at birth, every 3 months up to 18 months of age, and every 6 months thereafter. At last follow-up, 64 children were judged to be HIV infected and 343 had lost antibody and were presumed uninfected. The initial clinical feature in infected children was usually a combination of persistent lymphadenopathy, splenomegaly, and hepatomegaly, though 30% of children presented with AIDS, or with oral candidosis followed rapidly by AIDS. An estimated 83% of infected children show laboratory or clinical features of HIV infection by 6 months of age. By 12 months, 26% have AIDS and 17% die of HIV-related disease. Subsequently, the disease progresses more slowly and most children remain stable or even improve during the second year. The vertical transmission rate, based on results in 372 children born at least 18 months before the analysis, was 12.9% (95% Cl 9.5-16.3%). Virus has been repeatedly isolated in an additional small proportion of children (2.5%, 95% Cl 0.7-6.3%) who lost maternal antibody and have remained clinically and immunologically normal. Without a definitive virological diagnosis, the monitoring of immunoglobulins, CD4/CD8 ratio, and clinical signs could identify HIV infection in 48% of infected children by 6 months, with a specificity of more than 99%.

Mycobacterium gordonae is considered the least pathogenic of the Runyon Group II mycobacteria, although there are now well-documented reports of infection varying from localized soft tissue infection to disseminated life threatening diseases. We report a 40-year-old Pakistani housewife, treated in childhood for tuberculosis, who presented with severe systemic illness, fever, ascites, hepatomegaly, persistent dysuria with sterile pyuria, pulmonary disease, and anorexia with weight loss. Liver biopsy histology showed multiple granulomata and multiple isolation of M. gordonae from sputum and urine, in keeping with disseminated mycobacterial infection. She had dramatic response to antituberculosis therapy with streptomycin, isoniazid, rifampicin, and pyrazinamide. No evidence existed for disturbed humoral or cellular immunity and HIV infection. This represents the fifth reported case of disseminated M. gordonae infection, the first from the Arabian Gulf. It was treated successfully with standard antituberculosis regimen.

The clinical and microbiological finding of 34 patients with HIV infection and tuberculosis (30 were men), 32 were intravenous drug addicts. Fever, adenopathies, hepatomegaly and splenomegaly were the most encountered manifestations on admittance. 61.8% had a disseminated form of tuberculosis; the main locations were lymphatic (73.5%) and lung (64.7%). The detection of circulating viral antigen was associated with disseminated form of tuberculosis.
