Abstract
The serum levels of AST , ALT, bilirubin , BUN, and creatinine we significantly higher while serum albumin level was significantly lower among CLD patients as compared to controls. Prothrombin time was significantly prolonged among CLD patients as compared to controls. The percent of patients of CLD who had UTI in this study was 32.2% . Detection of UTI among the studied CLD patients and controls showed that it was more significantly encountered among CLD and LC patients when compared to the control group. Also, there was a significant difference between LC and CH. The occurrence of UTI among patients with different Child- Pugh classes was significantly higher when compared to controls. Patients with Child class C had a higher incidence as compared to those withclass B. This result indicates that UTI was more common among paients with more severe liver disease. Patients with UTI had significantly higher levels of pus cells, nitrite and RBCs compared to that of those without UTI. Both C3 and C4 levels were significantly lower among CLD patients with and those without UTI as compared to that of the controls. Serum level of C3 (but not C4) was significantly lower among CLD with UTI when compared to those without . This finding may indicate that deficiency of C3 may have arole in the occurrence of UTI and that it is one of the factors that lead to increased prevalence of UTI among CLD patients. Both C3 and serum levels were significantly lower among LC and CH patients when compared to the controls.
