View clinical trials related to Pyelonephritis.
Filter by:Urinary tract infections (UTI) are a common and important clinical problem in childhood.Upper urinary tract infections (ie, acute pyelonephritis) may lead to renal scarring, hypertension, and end-stage renal disease.Pathogenesis of acute pyelonephritis (APN) is associated with urinary tract anatomy and function, bacterial virulence factors, the host innate immune system and production of free radicals. Oxygen-free radicals and oxidative stress play a role in renal scar formation after an APN. Oxygen-free radical scavengers and antioxidants can reduce tissue damage and renal scaring during acute pyelonephritis.we want to publish a study that indicates that antioxidant therapy with omega-3 given to children with pyelonephritis may indeed lower the risk for renal scarring. Several studies show that omega-3 alleviated oxidative stress and inflammation.This study is a simple randomized clinical trial (RCT) evaluating the effect of omega-3 in addition to antibiotic on preventing renal scaring after acute pyelonephritis in children. This randomized clinical trial on 60 patients in 2 groups (intervention & control) is conducted.Children aged 1 month to 10 years with positive urine culture, clinical findings, and 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy-based evidence in favor of acute pyelonephritis were enrolled into a clinical trial. Patients with neurogenic bladder, systemic hypertension, obstructive uropathy and high grade vesicouretera are excluded.Patients in Intervention group are administered omega-3 based on body weight in divided doses in addition to antibiotic regimens and patients in control group received antibiotic regimens without omega-3. Primary outcome is the development of renal scar by doing DMSA renal scan on the 7th day of admission and four to six months after the intervention and compared between groups.Also,measurement of urinary biomarker of acute kidney injury (NGAL) three days after antibiotic or omega-3 administration for assessing of subsequent scarring in both groups will be done . Secondary outcome is the incidence and severity of renal scarring after pyelonephritis and response to treatment between two groups.
Risk factors for parenchymal damage in urinary tract infection are vesicoureteral reflux (VUR),obstructive uropathy,the number of flares of acute pyelonephritis(APN) and delay in treatment of acute infection.The pathogenesis of APN is related to bacterial virulenece,immune response,tissue factors,apoptosis and production of free radicals that lead to fibrosis and renal scarring. Oxidative stress in renal cells may be a critical factor in the pathogenesis of pyelonephritis whereas pharmacological management of the oxidative stress response may provide a therapeutic effect in preventing renal pathologies. Animal model show that L-carnitine alleviated oxidative stress, and acute renal inflammatory injury can be prevented much more effectively by carnitine in addition to conventional antibiotic treatment in pyelonephritis.This study is a simple randomized clinical trial (RCT) evaluating the effect of L-carnitine in addition to antibiotic on preventing renal scaring after acute pyelonephritis in children. Simple non- blind randomized clinical trial on 78 patients in 2 groups (intervention & control) is conducted.Children aged 1 month to 10 years with positive urine culture, clinical findings, and 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy-based evidence in favor of acute pyelonephritis were enrolled into a clinical trial. Patients were excluded if they had neurogenic bladder, systemic hypertension, obstructive uropathy. Patients in Intervention group are administered 50 mg/kg/day carnitine in divided 2-3 times/day (maximum 3 g/day) in addition to antibiotic regimens and patients in control group received antibiotic regimens. Primary outcome is the development of renal scar by doing DMSA renal scan on the 7th day of admission and six months after the intervention and compared between groups and secondary outcome is the incidence and severity of pyelonephritis and response to treatment.
Objective: To determine whether antibiotic treatment of asymptomatic bacteriuria in kidney transplant recipients could be useful to prevent pyelonephritis in these patients.
To evaluate the changes in the microcirculation of the liver, kidney and spleen during acute infection in patients with malaria (cohorts 1 and 3) and other infectious diseases such as acute pyelonephritis at day 0 (within 8 hours of the treatment start), day 2 to 4 and day 28-32, using functional US with continuous infusion of a contrast agent (SonoVue, Bracco, Italy). Study hypothesis: malaria patients should exhibit a different pattern of enhancement, particularly when quantitative measurements of the SU signals is performed with destruction reperfusion kinetics.
