The case of a 10.5-year-old girl, who was diagnosed with a case of thalassemia major at the age of 8 months and had been on regular blood transfusions since then, is related. Donor screening for HIV was started in mid-1988, thus she had received unscreened blood for a number of years. In February 1991, she presented with a dry persistent cough, moderate grade continuous fever, and breathlessness on exertion for over 2 weeks. Chest X-ray showed bilateral infiltrations. She was put on penicillin and chloramphenicol with a provisional diagnosis of bronchopneumonia. In March 1991, she had to be hospitalized for impending respiratory failure. After treatment with intravenous fluids and parenteral antimicrobials, her condition stabilized and she was discharged. In April 1991, she was readmitted because of complaints of difficulty in swallowing and weight loss. Her chest signs had persisted and she had developed oropharyngeal candidiasis with ulcerations. She also had alopecia, a generalized lymphadenopathy, digital clubbing, and bilateral parotid enlargement. Candidiasis responded to vigorous therapy with clotrimazole. Fine needle aspiration of lymph node showed a reactive hyperplasia. HIV antibodies were detected in the serum with ELISA and confirmed by Western blot. Immunologic tests showed evidence of severe immunodeficiency. The Multitest CMI, which simultaneously tests delayed skin hypersensitivity to seven common recall antigens, was totally nonreactive. She was classified as having AIDS according to World Health Organization criteria for children under 13 years of age. The diagnosis of lymphocytic interstitial pneumonitis (LIP) was also made based on the symptoms. Oral prednisolone was given 2 mg/kg/day in 3 divided doses for a month. The cough and dyspnea showed great improvement and the parotid swellings disappeared; lymphadenopathy, clubbing, and alopecia, however, persisted. The child was kept on maintenance therapy of prednisolone and on alternate day co-trimoxazole for prophylaxis against Pneumocystis carinii infection.

From June 1990 to August 1991, 21 patients infected with the human immunodeficiency virus (HIV) presented with systemic mycosis caused by Penicillium marneffei. Between August 1987 and August 1991, only five patients were observed who had P. marneffei infection but not HIV infection. The clinical presentation included fever, cough, and generalized papular skin lesions. For 11 of these 21 patients, the presumptive diagnosis of P. marneffei infection could be made by microscopic examination of Wright's-stained bone marrow aspirate and/or touch smears of skin specimens obtained by biopsy several days before the results of culture were available. Initial clinical response to treatment with either parenteral amphotericin B or oral itraconazole was favorable in most patients. Epidemiological and clinical evidence suggest that this systemic mycosis is caused by an important opportunistic pathogen and that it should be included in the differential diagnosis of AIDS, at least for countries in areas of endemicity, i.e., Southeast Asia and China.

The seroprevalence of antibodies to HIV-1, HTLV-I, and HCV was evaluated in three populations from northern rural Haiti: 1,727 patients attending the hospital for symptoms suggestive of HIV disease, 228 consecutive surgical patients, and 500 pregnant women were tested. HIV-1 seroprevalence was 6.1 and 4.0% in the last two groups, respectively, and 39.3% in the symptomatic population. Associated symptoms of wasting, cough, and diarrhea and a clinical diagnosis of AIDS were significantly predictive of HIV-1 seropositivity. Antibody to HTLV-I seroprevalence ranged from 2.2-5.3% in pregnant women, surgical patients, and HIV-seronegative symptomatic patients and was similar among the three groups when stratified by age. In contrast, HIV-1 seropositivity and HTLV-I seropositivity were significantly associated. The prevalence of confirmed antibody to HCV was low and not associated with either HIV-1 or HTLV-I seropositivity.

The purpose of this study was to investigate acute and time-related changes in lung function, i.e. forced expiratory volume in 1 second (FEV1), vital capacity (VC) and transfer factor (KCO) in HIV-infected patients with CD4 cell counts less than 400 x 10(6)/l. 66 males with no history of HIV-related pulmonary symptoms participated in a prospective lung function study for 9 months with 3-month intervals between examinations. 15/66 patients (23%) developed acute pulmonary symptoms, i.e. dyspnea (n = 12), cough (n = 13), fever greater than 38 degrees C (n = 13) and interstitial infiltrates on the X-ray (n = 9). Among the 51 asymptomatic patients, a significant time-related decrease in KCO (median decrease of 7%) was found, whereas no significant change in FEV1 or VC was observed during the study. Baseline KCO, i.e. KCO at entry, was found to be significantly higher in the asymptomatic patients (102% predicted (pred.) than in those patients who developed pneumonia (88% pred.). Development of pulmonary symptoms was both followed by a significant decrease in KCO (median decrease 17%), FEV1 and VC. We therefore conclude that HIV-infected patients with impaired immune function have in the absence of pulmonary symptoms a decrease in KCO. In case of pneumonia an acute decrease in both KCO, FEV1 and VC occurs.

Evidence from many countries suggests an association of human immunodeficiency virus (HIV) infection and tuberculosis of major public health significance. In order to begin assessing the impact of HIV on tuberculosis in Kenya, we have determined the HIV-1 seroprevalence among tuberculosis patients and compared the clinical characteristics of tuberculosis in HIV-positive and HIV-negative patients in two cross-sectional studies at the Infectious Disease Hospital (IDH) and the Ngaira Avenue Chest Clinic (NACC), Nairobi, Kenya. The diagnosis in 92% of all patients with pulmonary tuberculosis was confirmed by culture. The remainder were diagnosed on histological, clinical or radiological grounds. HIV seroprevalence among tuberculosis patients at IDH was 26.5% (52/196) compared to 9.2% (18/195) at NACC (P less than 0.001). There was no association between numbers of streptomycin injections in the previous 5 years and HIV infection. Positive sputum smear rates in HIV-positive patients were slightly lower than in HIV-negative patients at both study sites (71% vs 83% at IDH and 73% vs 82% at NACC) but the difference was not significant. Only Mycobacterium tuberculosis was isolated. Miliary disease was not associated with HIV infection. Persistent diarrhoea, oral candidiasis, generalized itchy rash, herpes zoster and generalized lymphadenopathy were all associated with HIV infection, but 46% (95% CI:38-54%) of all HIV-positive patients had none of the clinical features listed in the WHO Clinical Criteria for the Diagnosis of AIDS, apart from fever, cough and weight loss. Stevens-Johnson Syndrome was reported in 7/52 (13%) patients with HIV infection, and in 4/144 (3%) patients without (RR 4.85, 95% CI: 1.45-15.88).(ABSTRACT TRUNCATED AT 250 WORDS)

A report from Kampala, Uganda, compares the situation in 1991 to the state of chaos 10 years earlier when the regime of Idi Amin had been overthrown by Milton Obote's soldiers with the help of Tanzanian troops. Soldiers went on looting sprees, and 1 victim of their marauding became a 12-year old boy who got shot for refusing to part with his bike. In contrast, in 1991 things were much more peaceful; however, the AIDS epidemic was the new threat. The government radio transmits hourly warnings on HIV. Since President Museveni came to power, economy and security have improved radically. Shops and markets are open until late at night; public transport is reliable, and small scale industry flourished. There would be optimism about the future, if AIDS was not here. There is no doubt that the economy will soon be affected. According to the Kampala blood bank, 40% of the healthy population is already seropositive. In the hospitals the majority of admissions suffer from AIDS with diarrhea and an itching dermatitis; there is more cancer of the cervix and lymphoma; appendicitis is on the increase; and tuberculous lymph nodes are now quite common. Many of these patients have clinical AIDS. The government is frank about the situation and is active in preventive measures and education. Private charities and foreign aid organizations contribute. But the epidemic is so overwhelming, that some Western organizations might soon lose interest owning to meager returns on their efforts. A 6-year-old boy has grossly swollen lymph nodes around his neck, both parotids are painfully swollen, pus pours from the ears. A nonspecific cough and mild diarrhea are also present with an itching and sore herpes zoster on his left chest. the mother is frightened of losing him, and demurs at the hint of AIDS, since for her, AIDS means sexual promiscuity.

The range of clinical presentations of HIV-related disease in Africa has not been adequately described, despite the fact that many hospitals have to rely heavily on clinical diagnosis. Six hundred adult medical patients seen in the Casualty Department of the main Government hospital in Nairobi were enrolled in a study of the presentation and outcome of HIV-related disease: 506 of these patients were admitted, of whom 19 per cent (95) were HIV seropositive. The remaining 94 were dealt with as outpatients: 11 percent (10) of these were seropositive. A history of prior treatment for sexually transmitted disease and, if male, being uncircumcised, were associated with being seropositive. Three presentations were strongly associated with HIV infection: acute fever with no focus except the gastrointestinal tract (enteric fever-like illness), acute cough with fever (community-acquired pneumonia) and chronic diarrhoea with wasting. The WHO clinical case definition (CCD) for AIDS missed a substantial amount of HIV-related morbidity (sensitivity 39 per cent) and misidentified many seronegative patients (positive predictive value 59 per cent). In comparison with the Centers for Disease Control surveillance definition for AIDS, the CCD was specific (91 per cent) and sensitive (79 per cent) but only had a positive predictive values of 30 per cent: the CCD may therefore be a poor surveillance tool for AIDS. Seropositive patients were much more likely to die than were seronegative patients (39 per cent vs. 15 per cent mortality). Enteric fever-like illness was the presentation which most commonly proved fatal. A wider spectrum of disease is associated with underlying HIV immunosuppression than has previously been described in Africa.

4 cases of Pneumocystis carinii pneumonia in HIV-infected patients studied at the University of Zambia Medical School, Lusaka, were verified by bronchoalveolar lavage. Pneumocystis is common in North American AIDS patients, but has been considered rare in Africa. One reason may be that facilities for diagnosis, bronchoscopy with bronchoalveolar lavage, are not usually available. 44 consecutive HIV seropositive patients who were unresponsive to a 10-day course of antibiotics, and whose sputum was negative for acid fast bacteria, underwent bronchoalveolar lavage from February 1990 to December 1990. HIV status was assayed with Welcozyme ELISA kits, and P. carinii was detected with toluidine blue O stain. The 1st case of confirmed P. carinii pneumonia was a 35-year old man who had a productive cough for 4 weeks, fever, and dyspnea. He was treated with co-trimoxazole and was symptom-free in 3 weeks, but developed severe Stevens-Johnson reaction. His cultures were positive for M. tuberculosis at week 8. He was lost to follow-up. The 2nd case was a 26-year old man with a 6-month history of cough and white sputum, treated without effect with antituberculous medication. He improved over 3 weeks with co-trimoxazole, but died of respiratory failure 2 months later. The 3rd case was a 30-year old woman being treated for pulmonary tuberculosis, who became progressively dyspneic 7 months later. She developed a generalized maculo-papular rash after taking co-trimoxazole, so was given dapsone 100 mg/day, prednisone 1 mg/kg/day, and trimethoprim 15 mg/kg for 1 week. She improve in 3 weeks. The 4th case was a 30-year old man with a 4-week history of dry cough and dyspnea and recent high fever. He was given co-trimoxazole, but developed generalized purpura after 5 days. His treatment was changed to Dapsone 100 mg/day, prednisone 1 mg/kg/day, and antituberculous medication. He improved after 3 weeks, and is being maintained on Fansidar 1 tablet/week. These cases are remarkable because 2 of them also had pulmonary tuberculosis, which is often the presumed diagnosis of pneumonia in African AIDS patients. Furthermore, 3 developed serious drug reactions to co-trimoxazole, also considered an uncommon occurrence.

In 1990, among pregnant women .1% tested positive for HIV antibodies in Amsterdam compared to 24.5% in Lusaka, Zambia. During 1990 and 1991 data were collected from 231 patients fulfilling the WHO clinical criteria for the diagnosis of AIDS in 3 hospitals of Sesheke, a rural Zambian district. 46.3% of the group was male and 53.7% was female, and the mean age of women was significantly lower than that of men (25.2 vs. 31.1 years, p 0.001). A total of 185 patients could be tested for HIV-1 antibodies using ELISA-Welcozyme and HIVCECK-Du Pont. There were 141 (81.6%) positive results, 19 (10.3%) negative results, and in 15 (8.1%) cases the outcome was not clear. Seroprevalence figures for HIV-1 in the same period were 16% for blood donors and 41% for patients attending the clinic for sexually transmitted diseases. Most patients with AIDS in Sesheke district present with a wasting syndrome, and in these cases, tuberculosis (TB), whose incidence has increased dramatically, has to be excluded. Loss of more than 10% of body weight was the most common symptom followed by chronic cough lasting for more than 1 month, fever persisting for more than 1 month, and chronic diarrhea lasting for more than 1 more. Chronic coughing was more frequent among adults than among children (P 0.001). Weight loss, chronic diarrhea, persistent coughing, generalized lymphadenopathy, generalized dermatitis, and oropharyngeal candidiasis occurred among both adults and children equally often. Only 4 patients (18%) and extrapulmonary TB in 10 patients (4%). In the district there was no registration system for the dead and the follow-up of AIDS patients were not organized well, but as of January 1, 1992, from hospital records it was established that 74 patients out of the 231 studied were decreased. The outlook for the population in Sesheke and Zambia is dim in light of the current high seroprevalence rate.

Clinical and therapeutic features of 13 adult patients, diagnosed of Pneumonia Varicellosa are retrospectively reviewed, for the last ten years period, at Valle de Hebron General Hospital, Barcelona. Most of them had a cigarette consumption of over 20 per day, three of them showed simple chronic bronchitis criteria, and two had antibodies against HIV. Respiratory symptomatology, and dry cough, was present in 9 (75%), dyspnea in 7 (53%) and pleuritic pain in 6 (46%). Thorax radiology showed a bilateral interstitial pattern. IV aciclovir treatment was begun in patients with respiratory symptoms and hypoxemia (53%) with good therapeutic response.
