[Adult cerebral malaria. Actual experience of the Infectious Diseases Intensive Care Department at the Claude Bernard Hospital].

22 cases of adult cerebral malaria were observed between July 1987 and June 1989, either associated or not: parasitemia 5%, consciousness disorders, acute renal failure, thrombocytopenia. Two patients died (9%). Increased frequency of attacks is underlined. They are due to chloroquino-resistant parasite strains, even polychemoresistant, occurred in French speaking Tropical Africa since 1985. Therapeutic strategy is described. The necessity to use increased doses of quinine has been admitted, correlatively underlining importance of strict monitoring of the patients because, in first instance, the risk of hypoglycemia (eased by injecting too quickly high doses of quinine) and of acute pulmonary oedema (eased by too quick perfusions and/or transfusions).

[Anti-I anti-erythrocyte auto-immunization in malaria].

An anti-erythrocyte autoimmunization with anti-I specificity was shown in patients previously exposed to malaria (falciparum malaria in 98.7% of cases). An anti-I antibody was eluted from red cells in 14.6% of 41 patients with an acute P. falciparum infection. The frequency of the anti-I immunisation was found to be correlated to the rate of the antimalarial antibodies among the 152 patients without parasitaemia, coming from areas endemic for falciparum malaria: this frequency was 5.2% for a rate below 1/64, 9.7% for a rate between 1/64 and 1/256, and 34% for a rate above 1/1,024. Anti-I antibodies were more often noted in African patients coming from forest areas, considered as chronically infected with P. falciparum, and in other patients who have been in France for less than a month. No anti-I antibodies were found in the control group, composed of 52 Caucasian healthy subjects with no previous exposure to malaria. This anti-I immunisation was transitory and its disappearance was usually accompanied by a lowering of anti-malarial antibodies.
