Serological detection of Toxoplasma gondii in chronic renal failure patients and renal transplant recipients.
ABSTRACT Toxoplasma gondii antibodies were detected in 78 patients with renal disease by ELISA. Patients were classified according to the renal status; chronic renal failure patients not on haemodialysis (G1 = 19), chronic renal failure patients on regular haemodialysis (G2 = 30), renal transplant recipient (G3 = 29) and 13 normal controls. Anti-Toxoplasma IgG & IgM antibodies were 36.8% & 10.5% in renal failure patients not on haemodialysis, 56.7% &16.7% in patients on regular haemodialysis and 69% & 24.1% in renal transplant recipients versus 23.1% & 0% in controls with statistical significant difference for Toxoplasma IgG antibodies only. Anti-Toxoplasma IgG antibodies levels of G3 were lower than that of G1. It was observed that the more the exposure to dialysis, the more the risk of toxoplasmosis. It was found that 85.71% of renal transplant recipient seropositive cases for anti-Toxoplasma IgM antibodies were detected in one year post-transplantation and 14.28% of cases after the first year of transplantation.
