[Tubular interstitial disorders in the nephrotoxic action of antibiotics]
Abstract:
Experimental and clinical evaluation of antibiotic nephrotoxicity suggest a conclusion that these drugs may cause tubular damage in relatively unaffected function of tubular apparatus. Progression of tubular dysfunction results from accumulation of high concentrations of antibiotics in renal parenchyma due to tubular filtration and secretion of the drug by tubular epithelium cells. In the majority of patients the disease manifestations were directly associated with antibiotics administration. Tubular dysfunctions present as concentration, acid-excretion, glucose transport and beta 2-microglobulin reabsorption abnormalities. Though renal lesions proved benign, there were occasional cases of acute renal insufficiency in the absence of arterial hypertension.
Insights
Antibiotics can harm kidney tubules, leading to dysfunction. High drug concentrations in the kidney cause these issues, though renal lesions are typically benign.
Area of Science:
- Nephrology
- Pharmacology
- Toxicology
Background:
- Antibiotic use is widespread, necessitating an understanding of potential adverse effects.
- Kidney function is crucial for drug clearance and homeostasis.
- Previous studies have indicated potential renal toxicity associated with certain antibiotics.
Purpose of the Study:
- To evaluate the impact of antibiotic administration on kidney tubular function.
- To identify the mechanisms underlying antibiotic-induced tubular damage.
- To characterize the clinical manifestations of antibiotic nephrotoxicity.
Main Methods:
- Experimental models and clinical case evaluations were employed.
- Analysis of renal parenchyma and tubular function was performed.
- Correlation between antibiotic exposure and observed renal abnormalities was established.
Main Results:
- Antibiotics can cause tubular damage, affecting functions like concentration and acid excretion.
- Accumulation of high antibiotic concentrations in renal parenchyma contributes to dysfunction.
- Observed tubular dysfunctions include abnormalities in glucose transport and beta-2-microglobulin reabsorption.
- While renal lesions were generally benign, acute renal insufficiency occurred in some cases without hypertension.
Conclusions:
- Antibiotic nephrotoxicity primarily targets renal tubular function.
- Drug accumulation in the kidney is a key factor in developing tubular dysfunction.
- Clinical manifestations are diverse, ranging from mild functional deficits to acute renal insufficiency.
