Chloroquine splits autoantibodies from erythrocytes of patients with autoimmune haemolytic anaemia in vitro. After the removal of chloroquine from the samples the autoantibodies can be identified in the eluates. With one exception the autoantibodies of patients with idiopathic autoimmune haemolytic anaemia (AIHA) and severe haemolysis were completely split from the cells, whereas the autoantibodies of patients with symptomatic AIHA and moderate anaemia, of patients with diseases unrelated to haemolysis, and of healthy persons, were not completely split from the erythrocytes. In general, autoantibodies, which are associated with severe haemolysis, were more easily split from the red cells by chloroquine. The eluted IgG incomplete warm autoantibodies were only in part specific to Rh antigens. The Rh specificity does not correlate with the absence of presence of increased haemolysis. The inhibition of the autoantibodies and the splitting or 'loosening' of the antigen-antibody linkage with the immunocomplex by chloroquine could be responsible of a longer survival of autoantibody-coated red cells in patients with AIHA.

A 25 year-old primigravid woman developed chronic falciparum malaria at 23 weeks' gestation. Diagnosis was suspected on splenomegaly and haemolytic anaemia but without fever and confirmed by thin smears (Plasmodium falciparum) and serologic tests. She was successfully cured with chloroquine therapy. One week after her return from Cameroon, a 28 year-old woman was seen for malaria at 32 weeks' gestation. In spite of chloroquine therapy, foetal troubles appeared and a caesarean was performed. The newborn had an APGAR coefficient of 3 points and examination both of his blood films and the placenta revealed numerous trophozoites of P. falciparum. Chloroquine resulted in a rapid cure of the child. In endemic areas, parasitaemia is more frequent and dense during pregnancy, and especially in primigravidae. However, clinical symptoms remain rare because of acquired immunity. In case of no or loss of immunity, malarial infections are heavy and abortions are frequent. Congenital malaria is probably due to transplacental transfer of infected red blood cells of the mother. In endemic areas, the incidence is low due to the simultaneously transferred immunity. Emergency treatment is necessary because of life-threatening to both mother and child.

A 32-year-old woman in the 26th week of pregnancy became ill, 6 days after returning from a trip to Indonesia, with a fever up to 42 degrees C, haemolytic anaemia (haemoglobin 7.6 g/dl) and thrombocytopenia (7,000/microliters). She had not been on any malaria prophylaxis. Chloroquine, quinine and pyrimethamine, administered after macrogametocytes of Plasmodium falciparum had been found in the blood smear, eliminated the parasites from the peripheral blood, but respiratory failure and treatment-resistant pneumonia occurred, leading to the adult respiratory distress syndrome (Morel stage 4). Because of threatened intrauterine death (resulting from premature placental separation during artificial ventilation) the child was delivered by an emergency section. Despite extensive conventional therapeutic measures the mother's respiratory state progressively deteriorated so that extracorporeal membrane CO2 elimination was instituted on the 17th day. First signs of improvement in respiratory functions were noted after six days. The extracorporeal CO2 elimination was discontinued after twelve days, because artificial ventilation could now be adequately controlled. The woman was gradually weaned from the ventilator and discharged home without symptoms after a total of 11 weeks in hospital. Her child has not shown any neurological symptoms.
