Chronic Renal Failure Clinical Trial

Official title: Efficacy of Corticosteroids in Reducing Renal Scarring in Acute Pyelonephritis in Children:A Multi-centre, Double-blind, Randomized, Placebo-controlled, Clinical Trial

Status Recruiting

Clinical Trial Summary

Urinary tract infection (UTI) is the most frequently occurring serious bacterial infection in young children and accounts 5 to 14% of emergency department visits Formation of renal scarring in children has been associated with serious complications as hypertension, preeclampsia, and end stage renal failure in young age . So, this study aims to determine whether dexamethasone reduces the renal scarring in children will be treated with antibiotics for acute pyelonephritis. investigators propose to conduct a multi center, randomized, placebo-controlled, double-blind clinical trial, that will evaluate the efficacy of dexamethasone (0.3 mg/kg every 12 hours per day orally for 3 days) in preventing renal scarring in young febrile children (2 months to 14 years) with a first-diagnosed UTI. 120 Participants will be enrolled over a 3-year period from 6 sites.

Clinical Trial Description

Urinary tract infection (UTI) is the most frequently occurring serious bacterial infection in young children and accounts for 5 to 14% of emergency department visits. UTIs can be divided into asymptomatic bacteriuria, cystitis, and acute pyelonephritis (APN ). The APN is associated with an increased risk of renal damage, acquired through renal scarring. Which is a consequence of the inflammatory and immune response that aim to eradicate the bacteria involved in the UTI. Parenchymal infection can be solved, but there are a number of poorly understood factors that may perpetuate inflammation, and this would promote the formation of scarring. One of the most relevant factors involved in formation of renal scarring is the production of inflammatory mediators (complement proteins, bactericidal peptides, cytokines , chemokines, ). hence, the use of anti-inflammatory drugs may prevent the release of these mediators and the formation of permanent renal scarring. Renal scarring in childhood has been associated with serious complications as hypertension, preeclampsia, and ESRD in young age. Current treatment of children with UTI has focused on the treatment of vesicoureteral reflux (VUR) and on the early treatment of UTI with antibiotics. Although the presence of VUR increases the likelihood of bacteria gaining access to the kidney, correction of VUR is not sufficient to prevent scarring. Renal scarring frequently occurs in children who do not have VUR, and early diagnosis and treatment of children with VUR is not associated with a reduction in the incidence of end-stage renal disease. Similarly, early antibiotic therapy is necessary, but it is not sufficient to prevent renal scarring in most children with UTI. Because signs of UTI in children are relatively non-specific, the diagnosis is often delayed. data from many studies have shown that once the infection has localized to the renal parenchyma, treatment with antibiotics alone does not prevent scarring. hence ,It is clear that the current management is not always effective in preventing renal scarring. The proposed study aims to determine whether dexamethasone therapy - which focuses on modulation of the host inflammatory response - is effective in reducing renal scarring. ;
