Human immunodeficiency virus disease now accounts for 90% of all deaths among child-bearing urban Rwandan women. Many symptomatic seropositive patients may show some clinical improvement and should not be denied routine medical care. Easily diagnosed signs and symptoms and inexpensive laboratory tests can be used in Africa to identify those patients with a particularly good or bad prognosis.
The aim of the present study was to compare the clinical and radiographic presentation as well as the therapeutic outcome of pulmonary tuberculosis (PT) in adult patients with and without human immunodeficiency virus type 1 (HIV-1) infection in Kigali, Rwanda. Over a 17-month period 59 consecutive patients with bacteriologically and/or histopathologically documented PT were enrolled. Of these, 48 (81%) patients were HIV seropositive. Among these, 35 fit the WHO clinical criteria for AIDS (WHOCCA) at the time of admission. Significant differences were found between the HIV-seropositive and HIV-seronegative groups of patients: fever (85 versus 36%; p less than 0.001), tuberculin skin test anergy (69 versus 0%; p less than 0.01), mediastinal and/or hilar adenopathies (31 versus 0%; p = 0.05), and pleural effusion (43 versus 9%; p less than 0.05) were more frequently encountered in the HIV-seropositive group, and upper lobe infiltrates (55 versus 16%; p less than 0.02) and cavitation (91 versus 39%; p less than 0.003) were more often seen in the HIV-seronegative group. However, HIV-seropositive patients not meeting WHOCCA were less frequently anergic (0 versus 100%; p less than 0.001) and feverish (53 versus 97%; p less than 0.01) and more often had cavitation (69 versus 28%; p less than 0.02) and less often mediastinal and/or hilar adenopathies (7 versus 40%; p less than 0.04) compared with HIV-seropositive patients meeting WHOCCA. Under antituberculosis treatment, clearance of fever was slower in HIV-seropositive compared with HIV-seronegative patients, and among the HIV-seropositive group it was slower in those fitting WHOCCA.(ABSTRACT TRUNCATED AT 250 WORDS)
To determine the prevalence of Mycobacterium tuberculosis infection and the incidence of tuberculosis in HIV-infected and uninfected urban Rwandan women, 460 HIV-positive and 998 HIV-negative childbearing women were recruited from pediatric and prenatal care clinics and were enrolled in a prospective study in 1988 and followed for 2 yr. Tuberculin testing was administered 12 to 18 months after enrollment. Fifty-three percent of HIV-negative women had positive tuberculin tests (induration > or = 10 mm), with higher rates among older women and among women who had received BCG vaccine. Only 21% of HIV-positive women had positive tuberculin tests, with no relationship to BCG vaccine. Follow-up was available for 93% of subjects. Tuberculosis was diagnosed in 20 HIV-positive women and in two HIV-negative women. Features associated with an increased risk of tuberculosis among HIV-positive women included: age > or = 30, body mass index in the lowest quartile, low income, erythrocyte sedimentation rate > 75, positive tuberculin test, and chronic cough, chronic fever, and weight loss. Among Rwandan women who are infected with HIV, approximately half of those who are infected with M. tuberculosis do not have positive tuberculin tests. The rate ratio for development of tuberculosis among HIV-positive women was 22 (95% CI, 5 to 92). New algorithms are needed to improve the early detection of tuberculosis among HIV-positive patients in Africa.
We prospectively studied the demographics, the clinical and diagnostic features, the HIV-1 serostatus and the therapeutic response for all new patients with septic arthritis (SA) admitted to the Department of Internal Medicine of the Centre Hospitalier de Kigali, Rwanda, over a 19 month period. SA was diagnosed in 24 patients (10 male, 14 female), of whom 19 (79%) were HIV-1 seropositive (HIVpos). Gonococcal arthritis was found in four patients, all HIVpos. Non-gonococcal bacterial arthritis was established in 16 patients, of whom 13 were HIVpos. Causative organisms involved in this group and the corresponding HIV-1 serostatus of the patients were:
