Escherichia coli virulence factors and 99mTc-dimercaptosuccinic acid renal scan in children with febrile urinary tract infection.

Correlation of virulence factors of Escherichia coli with renal inflammation documented by 99mTc-dimercaptosuccinic acid renal scan was undertaken in 59 children with febrile urinary tract infections to identify more accurately the role of bacterial virulence factors in the development of pyelonephritis. P fimbriae were present in 63% of isolates from the positive scan group and 83% of those from the negative scan group (P = 0.126). Multivariate regression analysis showed no significant role for established E. coli virulence factors in the development of pyelonephritis. The pap genome was independently associated with negative scan (P less than 0.007) and with the absence of reflux (P = 0.031). E. coli pyelonephritogenic clone O16:K1:H6 was isolated from negative scan patients and did not produce hemolysin. We conclude that P fimbriae are important in the development of febrile urinary tract infection regardless of the level of infection. Virulent E. coli clones described in prior Scandinavian urinary tract infection studies were not common causes of pyelonephritis in our patient population.[1]
