Eleven children were identified as being seropositive for HIV-1 at the Ethio-Swedish Children's Hospital, Addis Abeba, Ethiopia between January 1988 and September 1989. The diagnosis was confirmed by both ELISA and Western blot methods performed at the National Research Institute of Health, Special Laboratory for AIDS. The mean age was 2 years and 5 months, with a range of 1 week to 10 years. There were 7 boys and 4 girls. The most common admitting diagnoses were pneumonia (5), gastroenteritis (5), marasmus (5), disseminated tuberculosis (4), and abandonment (3). One patient had extensive facial molluscum contagiosum. Symptoms at admission or during hospitalization included diarrhoea (9), failure to thrive (8), fever (7), and cough (7). Physical findings included hepatosplenomegaly (5), lymphadenopathy (3), and oral candidiasis (2). No patient with an opportunistic infection or radiographic evidence of lymphocytic interstitial pneumonitis (LIP) was identified. Five patients were classified as marasmic and 4 as underweight. Evidence suggestive of encephalopathy (developmental delay and/or microcephaly) was present in 5 patients. The VDRL was non-reactive in the 5 patients in whom it was tested. Nine children were presumed to have acquired the infection by perinatal transmission, though the passive transfer of maternal antibodies or postnatally acquired infection could not be excluded. One child was thought to have acquired the infection by blood transfusion. Three children died during their hospital stay. Paediatric HIV infection exists in Ethiopia; however, these children do not present with characteristic opportunistic infections but with signs and symptoms reflecting the most common paediatric problems seen in the country. Prevention of HIV infection in children entails the prevention of infection in women of childbearing age, counselling of infected women, and effective screening of blood products.

The natural course of HIV infection in 205 intravenous drug users (IVDU) presenting at 11 centers in Italy was followed since 1983. Criteria for entering the study were spontaneous attendance at the clinic from January 1983-April 1988; history of IVDU; dated negative HIV test and a positive test not over 18 months later. 13 of the 205 subjects developed AIDS by 30 April 1988, a total of 447.25 person-years, for an overall incidence of AIDS of 2.9% person-years. The clinical presentation was opportunistic infections in 7, wasting syndrome in 5, and encephalopathy in 1. No Kaposi's sarcoma was seen. The incidence of AIDS was 1.5% in the 1st year; 2.9% after 2 years; 9.9% after 3 years and 17.9% after 42-48 months. The risk of AIDS increased significantly 24 months after seroconversion. 11 others developed AIDS-related complex (ARC) in the 4-year period, an incidence of 3.4% person-years. The minor opportunistic infections seen were zona (4 cases), oral candidiasis (2), and hairy leukoplakia (1). 2 subjects had myelopathy. 87 others developed persistent generalized lymphadenopathy (PGL). 45.8% of the group remained asymptomatic. The subjects mean age was 26, and the sex ratio was 4:1 overall, but 12:1 among the AIDS group. The natural history of AIDS in this series closely resembled other reports on male homosexuals.

The HIV epidemic probably arose in Africa at about the same time as in the West, and there is a significant seroprevalence of HIV in the central African region. However, the epidemiology and clinical course of AIDS are different in Africa and in the West. In Africa males are infected as often as females, and the commonest means of transmission is heterosexual intercourse. Many HIV-infected people are symptomless, but many others present with or progress to generalized lymphadenopathy, pruritus, herpes zoster, herpes simplex, cellulitis, and oral candidiasis. The World Health Organization developed a clinical case-definition of AIDS in Africa, which was found to have a specificity of 90% and a sensitivity of 59% when tested in Zaire. The Kaposi's sarcoma seen in African AIDS patients is more aggressive than that seen in the West and is often visceral. Gastrointestinal AIDS (the "slim" disease) with weight loss and diarrhea is common in Africa, as are oral and esophageal candidiasis. In Africa Pneumocystis carinii pneumonia is rare, but pulmonary tuberculosis is common. Neurological manifestations include cerebral toxoplasmosis, cytomegalovirus infection, headache, and terminal encephalopathy. About 60% of infants born to seropositive women are infected and die within the 1st year of life. Lack of drugs and diagnostic facilities make both diagnosis and treatment of opportunistic infections difficult.

We report the neurological findings in two children with AIDS and one child with lesser AIDS. The first patient developed acute encephalopathy 37 months after having received a blood transfusion from a HTLV-III positive donor. CCT showed ring-enhancement and hypodense lesions with homogenous enhancement. Autopsy revealed CNS toxoplasmosis. The second child with AIDS, born to an iv drug-addicted mother, had one seizure at four months of age, but other neurologic signs were absent. She died of pneumonia due to Pneumocystis carinii at seven months of age. Postmortem examination of the brain revealed extensive nerve cell damage in the cerebral cortex and cerebellum, probably due to terminal hypoxemia and not AIDS-related. In both children clinical features of childhood AIDS like failure to thrive, lymphadenopathy, oral thrush and chronic pulmonary infiltrates were absent. The hallmark of the third child's clinical course was a progressive loss of psychomotor abilities with onset of the neurological symptoms nine months before other signs of AIDS occurred. AIDS should be suspected or excluded in children at increased risk for AIDS presenting with either acquired atypical CNS infection or unexplained developmental regression, even in the absence of other clinical symptoms of pediatric AIDS.

The transmission, diagnosis, and clinical manifestations of human immunodeficiency virus (HIV) infection in children up to 13 years of age are reviewed, and maintenance and prophylactic drug therapies for these patients are discussed. HIV can be transmitted from mother to infant in utero, during delivery, or through breast milk. Perinatal transmission accounts for almost 90% of all pediatric HIV infections. HIV infection can be diagnosed with HIV culturing, polymerase chain reaction testing, the enzyme-linked immunosorbent assay, the Western blot antibody assay, or the p24 core-antigen assay. Testing should begin as soon as possible after the at-risk child reaches one month of age. CD4+ lymphocyte counts are also used in diagnosis and monitoring. The median age at diagnosis of AIDS in children with perinatally acquired HIV infection is 12-24 months. Among the many possible clinical features are Pneumocystis carinii pneumonia (PCP), cytomegalovirus infection, failure to thrive, encephalopathy, recurrent bacterial infection, thrush, lymphoid interstitial pneumonitis, lymphadenopathy, pancreatis, hepatitis, anemia, and thrombocytopenia. Zidovudine is considered the drug of choice for initial therapy in HIV-infected children and is indicated for asymptomatic infection, early symptomatic disease, and advanced disease. However, new research is questioning the role of zidovudine monotherapy. Didanosine is the only agent with FDA-approved labeling for use as second-line therapy in children who do not respond to or become resistant to zidovudine. Agents under investigation for pediatric use are zalcitabine, stavudine, lamivudine, and nevirapine. Drug combinations, such as zidovudine plus didanosine, are also being examined. Zidovudine appears to reduce the rate of maternal transmission of HIV. Agents used prophylactically against PCP in children are trimethoprim-sulfamethoxazole, dapsone, and inhaled or i.v. pentamidine. HIV-infected children should also received prophylaxis against recurrent bacterial infections. The standard pediatric immunization schedule is used, but inactivated injectable poliovirus vaccine must be given instead of the live oral vaccine. Zidovudine remains the first-line agent for treating HIV infection in children. Alternatives are available for those who do not respond to zidovudine.

Eight of 13 children pre- or perinatally infected with the HIV virus subsequently developed neurological symptoms. Three children also had other nonspecific symptoms (fever, lymphadenopathy, diarrhoea, hepatosplenomegaly, failure to thrive and mucocutaneous thrush). Five children developed illnesses associated with AIDS (opportunistic infections, cachexia and lymphocytic interstitial pneumonia). The neurological abnormalities predominantly affected motor functions, only later also involving sensory ones. Motor, cognitive and language development was impaired in all eight children. A loss of developmental milestones occurred in three children with HIV encephalopathy: they have since died. In all the children the HIV infection caused symptoms within the first year, progressing more quickly in the three with encephalopathy. There were no discernible risk factors to account for the difference in the course of the disease.

A retrospective review of cases seen in the Diarrhea Treatment and Training Unit (DTU) of Bangalore (India) Medical College's Vani Vilas Children's Hospital during 1992-1994 confirmed the efficacy of the standard case management approach. This strategy entails oral rehydration therapy (ORT), continued feeding, and selective use of intravenous fluids and antibiotics. Of the 7966 children (4374 males and 3592 females) reporting to the DTU during the 2-year study period, only 2412 (30.5%) had received oral rehydration solution (ORS) or home-available fluids before admission. Acute watery diarrhea was present in 7316 cases (91.84%). Death occurred in 59 acute watery diarrhea cases, 6 dysentery cases, and 7 persistent diarrhea cases. The average time for cases managed in the ORT area was 2 hours and 45 minutes, while the hospital stay for admitted cases averaged 3 days. In 6957 cases (87.33%), ORS was sufficient treatment. Of the 1009 children (12.67%) who required intravenous fluids, 254 had dehydration attributable to conditions such as persistent vomiting and inability to drink due to oral thrush. Only the 512 children (6.2%) with cholera and dysentery received antibiotics. Of the 72 children who died (case fatality rate, 0.9%), 43 had associated severe malnutrition with pneumonia and anemia, 14 had a central nervous system infection, and 13 had septicemia; in only 2 cases could death be directly ascribed to diarrheal disease. One of these cases was due to shigella encephalopathy and the other to severe dehydration with acidosis. The average cost of treatment per patient was Rs 2.91 when only ORS was used compared with Rs 24.28 when intravenous rehydration was required. The finding that less than one-third of children had received ORS before admission suggests a need for the establishment of more DTUs in large hospitals that can train community-based health personnel in diarrhea case management.

A 2-year-old girl, who had prolonged thrush and spastic diplegia, was found to have a mother-to-child vertical transmission of human immunodeficiency virus type-1 (HIV). A brain computed tomography scan revealed a symmetrical calcification on the bilateral basal ganglia and periventricular white matter. She had an acquired immune deficiency syndrome (AIDS) encephalopathy of pure dominant pyramidal tract disorder without an intellectual deficit. Helper cell lymphocyte count (CD4) increased with the beginning of zidovudine (ZDV, also known as AZT) monotherapy but began to decrease after the 4th week to reach the baseline at 20th week. Zidovudine plus didanosine combination therapy was started at the 68th week, but because of intolerance, the combination was changed to ZDV plus lamivudine at the 98th week. By the 80th week, neither severe opportunistic infection nor deterioration of the neurological status was recognized, but chronic diarrhea appeared. The diarrhea advanced to the wasting syndrome at the age of 4 years and cytomegalovirus genome was confirmed in a biopsied specimen of the colon. Ganciclovir treatment was effective in stopping the diarrhea and increasing her bodyweight, but after the age of 5, resumption of diarrhea was followed by progressive emaciation and weakness. This work may provide some clues in treating children's AIDS.
