title: Circulating immune complexes in human acute leukaemia.
abstract: Circulating immune complexes (CIC) in the sera of 60 newly diagnosed leukaemic patients were investigated by two methods, 125I-C1q binding test (C1q-BA) and conglutinin binding assay (KgB-SP). Positivity percentages were respectively 20.0% (C1q-BA) and 28.3% (KgB-SP). The small overlap between the results of the two methods suggests the occurrence of different types of CIC. The presence of CIC was found to be related only to clinical haemorrhage and thrombocytopenia; it did not prove to affect the prognosis and the survival of leukaemic patient.
