RATIONALE: Kidney transplantation has become standard of care for carefully selected patients living with human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) in the highly active antiretroviral therapy (HAART) era. American and European prospective cohort studies have reported similar patient and graft survival compared with HIV-negative kidney transplant recipients. Despite an increased rate of acute rejection, partially due to drug interactions, HIV immunovirologic parameter generally remains under control during immunosuppression...

Purpose - Percutaneous nephrostomy (PCN) catheters are the primary method for draining ureters obstructed by malignancy and preventing a decline of the renal function. However, PCN-related infections such as pyelonephritis and urosepsis remain a significant concern. Currently no antimicrobial PCNs are available for preventing infectious complications. Vascular catheters impregnated with Minocycline/Rifampin (M/R) and M/R with Chlorhexidine coating (M/R+CHD) have previously demonstrated antimicrobial activity...

Background and Objective. Bacterial resistance to antibiotics traditionally used to treat uncomplicated urinary tract infections (uUTIs) is rising in Canada. We compared the cost-per-patient in Ontario of including fosfomycin (an antibiotic with a low resistance profile) as an option for first-line empirical treatment of uUTIs with current cost of treatment with sulfonamides, fluoroquinolones, and nitrofurantoin. Methods. A decision-tree model was used to perform a cost-minimization analysis. All possible outcomes of a uUTI caused by bacterial species treated with either sulfonamides, fluoroquinolones, nitrofurantoin, or fosfomycin were included...

Kidney transplant recipients (KTRs) taking immunosuppressive drugs have a 20-fold greater risk of nontyphoidal Salmonella (NTS) infection than the healthy adult population. Among KTRs, the urinary tract is the most common site of infection. However, few cases of urinary tract infection caused by NTS have been documented in KTRs, and only one in Japan. Furthermore, it frequently induces acute allograft rejection with high mortality. Salmonella enterica subsp. enterica serovar Schwarzengrund (S. Schwarzengrund) is now among the more common Salmonella serovars isolated in Japan and is likely to be invasive...

The treatment duration of acute uncomplicated pyelonephritis (AUP) is still under debate. As shortening treatment duration could be a means to reduce antimicrobial resistance, we aimed to establish whether 5 days of antibiotic treatment is non-inferior to 10 days in patients with AUP. We performed an open-label prospective randomized trial comparing 5 days to 10 days of fluoroquinolone treatment for AUP. The inclusion criteria were: female patients aged ≥18 years with clinical signs of urinary tract infection, fever >38 °C, and positive urinalysis...

The retroperitoneal fascial planes can be affected by various clinical disorders. In most of the cases retroperitoneal involvement occurs secondary to spread of a distinct underlying etiology. Herein we report two cases of primary retroperitoneal fasciitis diagnosed with imaging findings. The diagnosis of retroperitoneal fasciitis should be made by exclusion since various and more frequently encountered disorders including acute pancreatitis, duodenitis, pyelonephritis, and appendicitis may present with similar imaging findings...

Uropathogenic Escherichia coli (UPEC) are the primary causative agents of urinary tract infections. Some UPEC isolates are able to infect renal proximal tubule cells, and can potentially cause pyelonephritis. We have previously shown that to fulfill their physiological roles renal proximal tubule cells accumulate high concentrations of α-ketoglutarate (KG) and that gene cluster c5032-c5039 contribute to anaerobic utilization of KG by UPEC str. CFT073, thereby promoting its in vivo fitness. Given the importance of utilizing KG for UPEC, this study is designed to investigate the roles of two transporters KgtP and C5038 in KG utilization, their transcriptional regulation, and their contributions to UPEC fitness in vivo...

Extended-spectrum β-lactamase-producing Escherichia coli (ESBL-Ec) is a frequent cause of acute pyelonephritis (APN), requiring carbapenem therapy. However, alternatives to carbapenems are needed due to the emergence of carbapenemase-producing micro-organisms. The purpose of this study was to compare the clinical efficacy of piperacillin/tazobactam (TZP) versus ertapenem in the treatment of adult patients with APN caused by ESBL-Ec. A retrospective observational study of APN caused by ESBL-Ec susceptible to TZP was performed at a university-affiliated hospital in the Republic of Korea between February 2011 and June 2013...

A 53-year-old woman was referred to our hospital with a 40-mm splenic tumor, which was detected incidentally on abdominal computed tomography during hospitalization for pyelonephritis. The tumor was hypointense on T2-weighted imaging and gradually enhanced on dynamic study. The tumor increased in size over a six-month period. Since we could not exclude splenic malignancy, we performed laparoscopic partial splenectomy. Histological examination revealed multiple angiomatoid nodules with three distinct vessel types...
