Abstract

Plasma levels of antibodies against phosphatidylinositol (PI), phosphatidylcholine (PC) and cardiolipin (CL) were measured by enzyme-linked immunosorbent assay (ELISA) in patients from malaria endemic area of Sudan and The Gambia. Some Sudanese adults produced IgM antibodies against all three types of phospholipids (PL) during an acute Plasmodium falciparum infection. The anti-PL antibody titre returned to preinfection levels in most of the donors 30 days after the disease episode. IgG titres against PI, PC and CL were low. In Gambian children with malaria, IgM antibody titres against PI and PC were significantly higher in those with severe malaria than in those with mild malaria. These results show that a proportion of malaria patients produce anti-PL antibodies during infection and that titres of these antibodies are associated with the severity of disease.

摘要

通过酶联免疫吸附测定(ELISA)法,对来自苏丹和冈比亚疟疾流行地区的患者血浆中抗磷脂酰肌醇(PI)、磷脂酰胆碱(PC)和心磷脂(CL)的抗体水平进行了测量。一些苏丹成年人在急性恶性疟原虫感染期间产生了针对所有三种磷脂(PL)的IgM抗体。在疾病发作30天后,大多数献血者的抗PL抗体滴度恢复到感染前水平。针对PI、PC和CL的IgG滴度较低。在患有疟疾的冈比亚儿童中,患有严重疟疾的儿童针对PI和PC的IgM抗体滴度显著高于患有轻度疟疾的儿童。这些结果表明,一部分疟疾患者在感染期间会产生抗PL抗体,并且这些抗体的滴度与疾病的严重程度相关。
