Detection of schistosomiasis antibodies in urine patients as a promising diagnostic maker

To determine secreted antischistosoma antibodies in urine and to discern the epidemiological situation of schistosomiasis in the agricultural field labourers'camps city in the Gezira State-central Sudan.

Total of 66 urine and 66 serum paired samples were collected from those who confirmed parasitologically positive and negative with schistosomiasis from the two camps. Samples were tested using ELISA technique to measure and compare the immunoglobulin G (IgG) levels in serum and urine samples of schistosomiasis patients.

The overall prevalence of S. mansoni and S. haematobium was 53.8% and 15.4%, while the intensity were (2.04 GMEC) and (0.9 GMEC) respectively. The relative percentage of positive IgG individulas in urine was 92.40% where as 96.97% in serum. Statistically no significant difference between the IgG levels in serum and urine samples was observed.

This study shows that the detection of secreted IgG antibodies in urine can substitute serum for diagnosis of schistosomiasis.
