Evaluation of the effectiveness of dipstick haematuria and proteinuria in screening Schistosoma haematobium infection among school children in upper Egypt.
This study aimed at evaluation of validity and reliability of dipstick haematuria and proteinuria in screening school children for Schistosoma haematobium infection. It included a random sample of 400 school children aged 6-15 years in rural area of Fayoum Governorate, upper Egypt. Urine samples of the studied children were tested parasitologically by urine filtration technique as a reference test and semiquantitatively for haematuria and proteinuria using urine reagent strips as screening tests. Results of the study revealed that haematuria was a better indicator for Schistosoma haematobium infection than proteinuria, as it was more sensitive (85.5% 73.4%, respectively), specific (94.4% 82.9%, respectively) and reliable (kappa=92% 80%, respectively). Moreover, it had stronger relationship with intensity of infection (r=0.88 & 0.67, respectively). A combination of different grades of haematuria and proteinuria did not significantly increase either sensitivity or specificity. Dipstick haematuria could be a valuable technique in screening rural Egyptian school children who are at risk of urinary schistosmiasis.
