Abstract

Insights

Melatonin combined with antibiotics significantly reduces kidney damage and scarring in a pyelonephritis rat model. This combination therapy inhibits malondialdehyde production and neutrophil infiltration, offering a protective effect against renal damage.

Area of Science:

  • Nephrology
  • Pharmacology
  • Experimental Pathology

Background:

  • Pyelonephritis can lead to renal scarring and long-term kidney damage.
  • Antibiotic therapy is standard for pyelonephritis, but renal scarring can still occur.
  • Melatonin's antioxidant and anti-inflammatory properties suggest a potential role in mitigating kidney injury.

Purpose of the Study:

  • To investigate the efficacy of combined melatonin and antibiotic treatment in preventing renal scarring in an experimental pyelonephritis model.
  • To assess the impact of this combination therapy on oxidative stress markers and inflammatory responses.

Main Methods:

  • An experimental pyelonephritis model was established in rats via direct bacterial inoculation.
  • Treatment groups included no treatment, antibiotic (ceftriaxone) only, melatonin only, and antibiotic plus melatonin.
  • Kidney tissues were analyzed for malondialdehyde levels and histopathological changes (inflammation and scarring) after 6 weeks.

Main Results:

  • Combined antibiotic and melatonin treatment significantly reduced malondialdehyde levels compared to untreated and antibiotic-only groups.
  • Histopathological examination showed no significant difference in renal scarring scores between the combined treatment group and the control group.
  • Melatonin alone also reduced malondialdehyde levels, but did not significantly impact scarring scores compared to controls.

Conclusions:

  • Combination therapy with melatonin and antibiotics effectively prevents renal scarring in experimental pyelonephritis.
  • Melatonin's inhibition of malondialdehyde production and neutrophil infiltration contributes to its protective effect against antibiotic-induced renal damage.
  • This combination therapy holds promise for improving outcomes in pyelonephritis patients by reducing long-term kidney damage.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
