Since the ACE gene deletion polymorphism is a known risk factor for progressive glomerulosclerosis in chronic renal diseases, we have investigated the relationship between the ACE genotypes and the development of renal scarring after APN.
ACE gene D allele is associated with a twofold increase in RPS risk, which could be a result of a functional effect to increase tissue levels and activity of ACE during APN.
In total, 103 E. coli strains isolated from patients with acute pyelonephritis (59 uncomplicated pyelonephritis (UAP) and 44 complicated pyelonephritis (CAP)) were characterized by RFLP of the intergenic spacer region 16S-23S rRNA, the presence of three alternative sequences found in the polymorphic V6 loop of the 16S rRNA gene, the presence of the pap gene, and antibiotic susceptibility.
Genotyping was performed in 479 patients with severe acute pyelonephritis (UTI, n = 146), community-acquired pneumonia (CAP, n = 109), intra-abdominal infections (IAI, n = 119), and primary bacteremia (BSI, n = 105) by restriction fragment length polymorphism of the polymerase chain reaction (PCR) product and compared with 104 healthy volunteers.
The studies suggest that distinct molecular defects can cause the clinical entity of acute pyelonephritis with renal scarring, and suggest that the susceptibility to UTI in certain patient groups may have a genetic basis.
By modifying specific aspects of the innate immune response to UTI, genetic variation either exaggerates the severity of acute pyelonephritis to include urosepsis and renal scarring or protects against symptomatic disease by suppressing innate immune signaling, as in asymptomatic bacteriuria (ABU).

The aim of the present study was to investigate the effects of IL-1beta and Escherichia coli on the expression and secretion of MIP-2, the mouse equivalent to human IL-8, MCP-1 and RANTES in the kidneys of mice with acute pyelonephritis.

The area under the curve (AUC) value from the receiver operating characteristic (ROC) curve of D-dimer (0.621, P = 0.046, 95% CI: 0.499-0.743) for prediction of VUR was higher than other inflammatory markers, but was inferior to CRP in predicting APN.
Receiver operating curve (ROC) analyses showed good diagnostic profiles of NGAL, PCT, CRP, and WBCs for identifying APN [area under the curve (AUC) 0.893, 0.855, 0.879, and 0.654, respectively].
Multivariate analysis revealed that serum albumin level and CRP were the significant risk factors for the development of uroseptic shock from calculous APN.

Statistical analysis revealed that only IL-8 (rs4073, -251A>T) showed significant differences in genotype and allele frequency between the control and APN or ALN cases.
