Virological and polymerase chain reaction studies of HIV-1/HIV-2 dual infection in Côte d'Ivoire.

Dual serological reactivity to the human immunodeficiency virus (HIV) types 1 and 2 is common in Côte d'Ivoire. To assess whether dual infection is the reason for dual seropositivity we sought HIV-1 and HIV-2 proviral DNA in primary uncultured peripheral blood mononuclear cells from selected seropositive patients in Côte d'Ivoire with the polymerase chain reaction (PCR). PCR on primary lymphocytes in 36 dually seropositive samples revealed the presence of both HIV-1 and HIV-2 proviral DNA in 12 cases and the presence of HIV-1 only in 24 cases.

[Complications of chickenpox seen in 44 patients in Abidjan].

The prevalence of complications is 38% in 116 patients with varicella. Cutaneous surinfection is observed in 30 patients (26%), pneumopathy in 4 cases resulting in death of 3 patients, encephalitis in 3 patients (1.7%).

Modifications of hemato-biological parameters in pregnant women in a migrating population in northern Cameroon: prevalence of anemia, iron and folates deficiencies.

The wholesale displacement of a population can have nutritional consequences for the migrants. With this in mind, the prevalences of anemia and of iron and folic acid deficiencies were studied in a group of 90 pregnant women living in northeast Benoue, an area situated in northern Cameroon where a development project was initiated in 1973. This project aimed at moving a population from the extreme northern highlands to the fertile valley of the Benoue.
