Summary
Gentamicin and ceftriaxone effectively treat acute pyelonephritis (APN) in rats. However, combining gentamicin with mycophenolate mofetil worsened kidney function, suggesting potential compound incompatibility in APN treatment.
Area of Science:
- Nephrology
- Pharmacology
- Infectious Diseases
Background:
- Acute pyelonephritis (APN) is a serious kidney infection causing inflammation and potential malfunction.
- Effective antibiotic treatment is crucial for managing APN and preventing kidney damage.
Purpose of the Study:
- To assess the therapeutic effects of gentamicin (GEN) and ceftriaxone (CEF) alone and combined with mycophenolate mofetil (MMF) in an experimental APN model.
- To investigate potential adverse interactions between antibiotics and immunosuppressants in APN.
Main Methods:
- Acute pyelonephritis was induced in Wistar rats using E. coli injection.
- Rats were treated for two weeks with saline, GEN, CEF, MMF, or combinations (GEN+MMF, CEF+MMF).
- Kidney function was evaluated via blood counts, creatinine, BUN levels, and histopathology.
Main Results:
- GEN and CEF treatment normalized elevated white blood cells, creatinine, and BUN levels in APN rats.
- Co-administration of GEN with MMF significantly increased creatinine and BUN, indicating worsened kidney damage.
- Histopathology confirmed that GEN and CEF alone partially restored kidney tissue, while GEN+MMF combination therapy failed to reduce APN-induced damage.
Conclusions:
- Gentamicin and ceftriaxone are effective in treating experimental acute pyelonephritis.
- Combining gentamicin with mycophenolate mofetil may exacerbate kidney damage in APN, possibly due to compound incompatibility.
- Further research is needed to understand the adverse effects of combined therapeutic regimens in APN.

01:15Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations
Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...
01:28Acute 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...
01:27Acute 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,...
01:27Combined Effects of Drugs: Synergism
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

01:25Inhibitors of Bacterial Protein Synthesis
Aminoglycosides constitute a highly potent class of bactericidal antibiotics that exert their antimicrobial effects by targeting the bacterial ribosome, specifically disrupting protein synthesis. These polycationic molecules consist of amino-modified sugars linked via glycosidic bonds to an aminocyclitol core such as 2-deoxystreptamine or streptamine. Their strong positive charges facilitate tight binding to the negatively charged phosphate backbone of ribosomal RNA (rRNA), primarily at the 16S...
