[Malaria and anemia of pregnancy in an African savanna zone. Epidemiological, hematological, biological and immunological study of 2 villages of the Bamako region, Republic of Mali]

Abstract

An haematological, biological, parasitological and immunological study about anaemia of pregnancy was carried out in two rural village of Mali Republic, where P. flaciparum malaria is hyper-endemic. The 25 pregnant women found in the villages were compared with 23 controls. One could observe that anaemia more often normochromic and regenerative usually appears during the second trimestre of pregnancy. Only a few cases with haemaglobin levels below 8 g. % are hypochromic. Serum transferrin levels were slightly higher among pregnant. None among 31 bone marrows examined showed megaloblastic changes. Haptoglobin levels below 10 mg. % were observed in 3/4 of the pregnant women versus 1/4 in controls. Like some others, this study confirms the primary responsability of malaria haemolysis in the aetiology of anaemia of pregnancy and the interest of systematic chemoprophylaxis, at least from the third month of pregnancy. Vitamin and iron therapy is to consider therafter in hyper-endemic areas of P. falciparum malaria when nutritional problems are not predominant.
