Frequency of urinary tract infection in pediatric liver transplantation candidates.
An increased frequency of infections has been reported in patients with chronic liver disease. The tendency of patients in this population to acquire UTI is not completely understood. We aimed at investigating the incidence of UTI in children with cirrhosis, before liver transplantation. Twenty-six children (9 girls, 17 boys; mean age, 7.66 +/- 5.73 yr) with chronic liver disease who had undergone liver transplantation between 2002 and 2004 were included. On admission for liver transplantation, patients were examined for presence of UTI. Serum biochemistry, complete blood cell count, urinalysis and culture, glomerular filtration rate, and abdominal ultrasonography were performed prior to liver transplantation. Ten of 26 patients (38.5%) were found to have symptomatic UTI. Urine cultures revealed E. coli in five (50%), Klebsiella pneumoniae in three (30%), Enterococcus faecalis in one (10%), and Enterobacter aeruginosa in one (10%) patient(s), respectively, as etiologic factors. The etiologies of chronic liver disease in our patients with UTI were BA in five, PFIC in three, Wilson's disease in one, and alpha-1 antitrypsin deficiency in one patient. We found a significantly greater number of UTIs in patients with biliary atresia than in those without biliary atresia (p < 0.05). The mean age of the patients with UTI was 2.75 +/- 3.49 yr, which was significantly lower than in those without UTI (9.75 +/- 4.86 yr, p < 0.05). Levels for white blood cells, thrombocytes, ALT, and alkaline phosphatase were significantly higher in patients with UTI than in those without UTI. There were no significant differences between the groups with regard to serum albumin, bilirubin, AST, GGT, BUN, or creatinine levels, glomerular filtration rate, duration of disease, and PELD scores. In patients with bacteriuria, renal USG revealed normal findings in all, but except one patient who had pelvicalyceal dilatation. Scintigraphic findings demonstrated acute pyelonephritis in six (60%) patients with UTI. VCUG demonstrated vesicoureteral reflux in two patients. In conclusion, symptomatic UTI is common in children with cirrhosis. It occurs more frequently in patients with biliary atresia than it does in patients with other types of chronic liver disease. In febrile children with chronic liver disease, UTI should be considered in the differential diagnosis.
