Lack of P2X Receptors Protects against Renal Fibrosis after Pyelonephritis with α-Hemolysin-Producing Escherichia coli.

Am J Pathol 2019 Mar 27. Epub 2019 Mar 27.

Department of Biomedicine, Aarhus University, Aarhus, Denmark. Electronic address:

Severe urinary tract infections are commonly caused by sub-strains of Escherichia coli secreting the pore-forming virulence factor α-hemolysin (HlyA). Repeated or severe cases of pyelonephritis can cause renal scarring that subsequently can lead to progressive failure. We have previously demonstrated that HlyA releases cellular ATP directly through its membrane pore and that acute HlyA-induced cell damage is completely prevented by blocking ATP signaling.

Urinary tract infection (UTI) represents the most common infection after kidney transplantation; it is associated with an increased risk for acute kidney rejection and impaired graft function in the early post-transplant period. Kidney transplant recipients with UTIs are often clinically asymptomatic due to the immunosuppressive therapy; however, asymptomatic bacteriuria may progress to acute pyelonephritis, bacteremia and urosepsis, particularly in the early post-transplant period, that are independent risk factors for short and long-term graft and patient survival. This article reviews the definitions, incidence, risk factors and the management of UTI in kidney transplant recipients; furthermore, the main controversial and still unanswered questions, regarding the causes of recurrent UTIs, adequate use of antibiotics to avoid antibiotic resistance, dosing and timing for prophylaxis and treatment of symptomatic infections, are also discussed.

Population Pharmacokinetic Analyses for Plazomicin Using Pooled Data from Phase 1, 2, and 3 Clinical Studies.

Antimicrob Agents Chemother 2019 Apr 27;63(4). Epub 2019 Mar 27.

Institute for Clinical Pharmacodynamics, Inc., Schenectady, New York, USA.

Plazomicin is an aminoglycoside with activity against multidrug-resistant Plazomicin is dosed on a milligram-per-kilogram-of-body-weight basis and administered by a 30-min intravenous infusion every 24 h, with dose adjustments being made for renal impairment and a body weight (BW) of ≥125% of ideal BW. A population pharmacokinetic analysis was performed to identify patient factors that account for variability in pharmacokinetics and to determine if dose adjustments are warranted based on covariates. The analysis included 143 healthy adults and 421 adults with complicated urinary tract infection (cUTI), acute pyelonephritis, bloodstream infection, or hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia (HABP/VABP) from seven studies (phases 1 to 3).

Mitochondria-Associated Matrix Metalloproteinases 2 and 9 in Acute Renal Pathologies.

Bull Exp Biol Med 2019 Jan 9;166(3):334-338. Epub 2019 Jan 9.

A. N. Belozersky Research Institute of Physico-Chemical Biology, M. V. Lomonosov Moscow State University, Moscow, Russia.

Activities of MMP-2 and MMP-9 in the cytoplasm and mitochondria of kidney cells were evaluated on the models of acute renal pathologies: pyelonephritis, rhabdomyolysis, and ischemia/reperfusion of the kidney. In acute pyelonephritis, a significant increase in the level of MMP-2 and MMP-9 in kidney cells and the appearance of mitochondrial MMP-2 isoform with a lower molecular weight, but still exhibiting proteolytic activity were observed. A direct correlation between the level of MMP-2 and MMP-9 in the kidney and the severity of inflammation in pyelonephritis was revealed. Read More
