Non-Secretion of blood group antigens and susceptibility to urinary tract infection

ABSTRACT

The material of the present study comprised 103 patients of urinary tract infection confirmed by bacterial examination of urine, [64] out of them had chronic renal failure, due to recurrent urinary tract infection these patients underwent determination of blood group [ABO and Lewis] and secretor status, to find out if there is relation between it and susceptibility to urinary tract infection. There was a predominance of blood group AB and non secretor status [Se Se] which proves that the absence of A and B antibodies and also absence of Se gene combine to give an increased risk to urinary tract infection. The appearance of increased frequency of Lea [a-b] in non secretors confirms the consumption of Le antigen as receptors for pathogenic organisms.There is no predominance of special blood groups in patients not confirmed to be recurrent
