Do AB0 blood groups affect lower urinary tract symptoms?

The aim of this study is to investigate whether there is a correlation between AB0 blood group antigens and Rhesus factor and lower urinary tract symptoms (LUTS).

A total of 556 male patients applying to our clinic with LUTS complaints from April 2012-2015 and complying with the study criteria were included in the study. The patients were divided into two groups as those with (Group 1; n=283) and without LUTS (Group 2; n=273) complaints. The effect of blood groups on LUTS complaints was compared using univariate logistic regression analyzes.

According to AB0 blood groups, blood groups A (56.7%) and AB (56.9%) were most common in the LUTS group. But 0 blood group (44.1%) was the least common. According to rhesus factor, the incidence of LUTS in Rh (+), and Rh (-) groups were 48.9%, and 66.7%, respectively. Compared to 0 blood group, the LUTS incidence was 1.65, and 1.66 times higher for individuals with blood groups A, and AB, respectively. The same risk increased 2.09 times for individuals with Rhesus factor negative.

This study identified a correlation between AB0 blood group and Rhesus factor and LUTS. The risk of LUTS risk increased in individuals with blood group A Rh (). Additionally there was a clear risk increase observed for AB blood group, though this did not reach statistical significance.
