Rats with retrograde proteus pyelonephritis were treated with antibiotics until their kidneys became sterile. Using fluorescent antibody techniques, specific P. mirabilis antigen was found in some sterile pyelonephritic kidneys 20 weeks after cessation of treatment and presumed renal sterilization. Persistent antigen was associated with interstitial chronic inflammation but not with acute infla...

The results of scintiphotography with gallium-67 (67Ga), renography with technetium-99m diethylene triamine penta-acetic acid, immunofluorescence of antibody coated bacteria, and determination of renal beta 2 microglobulin excretion were compared in 19 patients with upper and 15 patients with lower urinary tract infection. All patients with acute pyelonephritis showed an appreciable unilateral ...

Emphysematous pyelonephritis is an acute infection of the renal parenchyma and perinephric tissues caused by gas-forming microorganisms, resulting in the radiographic presence of gas in the kidney, collecting system, and surrounding spaces. Here we present a case of severe emphysematous pyelonephritis in the setting of Klebsiella urosepsis. Surgical exploration of the flank revealed infectious ...

Background Platelets have an important contribution in pathogenesis of different infectious and inflammatory disorders. This study was performed to identify the diagnostic value of platelet count (PLT), and platelet indices in children with acute pyelonephritis (APN).  Materials and Methods In a cross sectional case control s...

Staphylococcus xylosus was recovered from the urine of a patient with pyelonephritis. Antibodies against the teichoic acid of the microorganism were demonstrated in the patient's serum by the agar gel diffusion technique.

BACKGROUND For unknown reasons, urinary tract infections (UTIs) are clustered in certain individuals. Here we propose a novel, genetically determined cause of susceptibility to acute pyelonephritis, which is the most severe form of UTI. The IL-8 receptor, CXCR1, was identified as a candidate gene when mIL-8Rh mutant mice developed acute pyelonephritis (APN) with severe tissue damage. METHODS ...

Background and Purpose: Emphysematous pyelonephritis (EPN) is a rare and serious disease causing acute renal failure. Diabetes is a major risk factor for this infection. Case report: Herein, we present the case of a 55-year-old female patient with diabetes and EPN caused by Candida albicans. The infection was complicated with endophthalmitis and endocarditis. The results of antifungal suscep...

PURPOSE This study examined the clinical effectiveness of parenteral cefuroxime and cefotaxime as empirical antibiotics for treating hospitalized women with uncomplicated acute pyelonephritis (APN). MATERIALS AND METHODS This study was based on the clinical and microbiologic data of 255 hospitalized women with APN. Of these 255 women, 144 patients received cefuroxime and 111 received cefotaxi...

BACKGROUND To formulate a classification tool for early recognition of patients admitted with acute pyelonephritis (AP) who are at high risk for failure of treatment or for death. METHODS A retrospective chart review of 225 patients (102 men) admitted with AP. We considered 13 potential risk factors in a multivariate analysis. RESULTS Recent hospitalization, previous use of antibiotics, and...

INTRODUCTION The choice of empiric therapy of acute pyelonephritis (APN) in children should be based on the knowledge of Escherichia coli (E. coli) as the most common uropathogen and its antibiotic sensitivities considering that nowadays ESBL-producing [ESBL (+)] E. coli is on the rise worldwide. OBJECTIVE To examine in vivo susceptibility of ESBL (+) E. coli to ceftriaxone (CTX), and to eval...
