[Intrathecal synthesis of anti-Toxoplasma gondii antibodies during cerebral toxoplasmosis associated with African AIDS].

Thirty-four HIV-1-infected in-patients of the Hôpital Central des Forces Armées Congolaises, Brazzaville, Congo, hospitalized for suspected cerebral toxoplasmosis, have been evaluated for integrity of the blood-brain barrier, intrathecal synthesis of total IgG, toxoplasmic serology in blood and cerebrospinal fluid, and for intrathecal synthesis of IgG to Toxoplasma gondii. An empiric scale to gauge the possibility of clinical cerebral toxoplasmosis was used to classify the patients (+, +2, +3). Only an intrathecal synthesis of IgG to Toxoplasma gondii was found to be associated with suspected cerebral toxoplamosis: it was found in about 80% of patients, and more frequently in patients with a higher probability of disease.

[Impact of AIDS on the resurgence of tuberculosis and reduced availability of hospital beds in Brazzaville (Congo)].

Our objective was twofold: firstly to evaluate the impact of AIDS on the annual increase of tuberculosis morbidity in Brazzaville; and secondly, to show its consequences on the reduced availability of hospital beds for patients treated for diseases nonrelated to AIDS. This retrospective study included 541 tuberculosis patients who were treated from 1988 to 1992 in the Department of Medicine at the Military Central Hospital in Brazzaville. The serum of all patients was tested by ELISA and Western blots for the presence of HIV.

[Toxoplasmosis and cytomegalovirus serology in patients infected with HIV in Congo].

Cerebral toxoplasmosis and cytomegalovirus (CMV) infection are very frequent in AIDS. Biological markers of toxoplasmosis and CMV were studied in blood and cerebrospinal fluid (CSF) of 121 HIV-positive and 35 HIV-negative patients in the Central Hospital of the Congolese Army in Brazzaville. In the case of clinically suspected cerebral toxoplasmosis, the simultaneous presence of specific IgG antibodies in the blood and in the CSF can be considered as having complementary diagnostic value (PPV = 63.

[Peripheral and bone marrow hematological modifications in infection by the human immunodeficiency virus (HIV) in central Africa. Diagnostic and prognostic significance].

From the 24 March 1988 to the 15 June 1989, we noticed the peripheric and medullar haematologic modifications of 46 patients infected by HIV, classified in the group IV of CDC. The haematologic modifications found are: a peripheric cytopenia with a constant anemia often serious, a leuconeutropenia, a mild or missing lymphopenia. In comparison: the bone marrow is often rich in the different lineage with more often a sharp lymphoplasmocytal reaction, sometime very characteristic on the cytological side.

[Retrospective study of infection by the human immunodeficiency virus in pregnant women. Future of the child and the mother].

5.4% (108 of 2,000) women have been confirmed for HIV 1 infection in Brazzaville in 1987. 1,172 deliveries have been registered by study, 7.

[Hematologic parameters during human immunodeficiency virus (HIV) infection in various Congolese subpopulations].

Study of 220 haematological profiles in women, men and children was realized in National Laboratory of Public Health and in Central Army Hospital in Brazzaville. The red cells count the haemoglobin level, the leucocytes and eosinophilia leukocyte counts in each sub-group of HIV+ and HIV- patients were compared. The anemia is important in HIV+ patients (Center for Diseases Control IV).

[Clinical and developmental aspects of acquired immunodeficiency syndrome in the Congo (the experience of the medical service of the Hôpital Central des Armées Pierre Mobengo - Brazzaville)].

During a period of 20 months, 204 cases of AIDS were diagnosed among adults in the Medicine Department of the Pierre Mobengo Armed Forces Central Hospital, Brazzaville. The authors review the clinical and evolutive aspects in admitted patients during these period of time, taking into consideration the problems of diagnosis, treatment and monitoring, according to the conditions of practice. Individuality of AIDS in Central Africa is underlined by its different features.

[Role of delta viruses in fulminating hepatitis in Central Africa].

The delta virus (DV) was shown to be the predominant but not exclusive aetiology in 124 cases of fulminating hepatitis (FH) in the Central African Republic. The condition occurs in an endemo-epidemic form in young adults with no apparent risk factors. The mortality is high (88 p.

[A case of histoplasmosis caused by Histoplasma duboisii and treated by ketoconazole in Bangui (C.A.R.)].

The authors report on one case of histoplasmosis in a young girl aged of 12, showing about 200 ulcerous vegetative lesions distributed on her body. Several different therapies were used without success. Utilization of ketoconazole during 187 days lead to a very favourable course.

[Clinical aspects of AIDS in the Central African Republic].

AIDS is known in Central African Republic since 1983: 64 recognized cases have been registered. AIDS is of endemic aspect presenting the main following signs: lost of weight (100%), degeneration of the health status (80%), lymphadenopathy (46%), pneumopathy (44%), diarrhea (40%), candidiasis (21%), Kaposi's disease (16%), purpura (8%), pruritus (8%), Cutaneous anergy to tuberculin or to the 7 antigens (Merieux test) is constant. LAV serology was positive in 61 cases.

[Bacteriological and clinical aspects of Salmonella typhi infections in the Central African Republic. Evaluation of a 3-year study in Bangui].

Authors have isolated and identified 229 strains from patients with typhoid syndrome . The bacteriology of each strain was studied. We have observed the extension of A (subtype Dakar) lysotype to Central Africa from West Africa.
