(A,B) Correlation of plasma anti-PS IgG antibodies with the LDH levels (A) or with the erythrocyte lysis capacity (B) of the plasma of P. falciparum patients. (C) Complement-mediated lysis of erythrocytes exposing PS by P. falciparum patient’s plasma compared to plasma from uninfected controls, expressed as percentage of maximal lysis. (D) Complement-mediated lysis of erythrocytes exposing PS, pre-incubated or not with Annexin V, before incubation with the plasma of P. falciparum patients (n = 6). Results show the means and standard deviations of triplicated determinations. Significance was assessed by nonparametric Spearman correlation analysis (A,B) or unpaired Student's t-test (C,D). *p≤0.05, **p≤0.01.
