Mechanisms and management of amphotericin B-induced nephrotoxicity
1Department of Nursing, Sinai Hospital of Baltimore, MD 21215, USA.
Purpose:
The author outlines the care of patients receiving intravenous amphotericin B, with emphasis on the prevention and/or management of nephrotoxicity.
Overview:
The immunocompromised patient remains at risk for systemic fungal infections; however, therapeutic options are limited. Although amphotericin B has remained the drug of choice for more than 30 years, its toxic effects, particularly nephrotoxicity, warrant careful attention. Nephrotoxicity is the most serious and dose-limiting effect of amphotericin B therapy. Appropriate assessment before, during, and after therapy in patients receiving intravenous amphotericin B may help to minimize the potential for nephrotoxicity.
Clinical Implications:
To provide optimal patient care, it is imperative that the clinician understand the etiology of and the signs and symptoms associated with nephrotoxicity, as well as interventions to prevent nephrotoxicity, in the patient receiving amphotericin B.
Insights
Managing amphotericin B (AMB) therapy requires careful attention to prevent kidney damage. Early assessment and intervention are key to minimizing AMB-induced nephrotoxicity in at-risk patients.
Area of Science:
- Pharmacology
- Nephrology
- Infectious Diseases
Background:
- Systemic fungal infections pose a significant risk to immunocompromised patients.
- Amphotericin B remains a primary antifungal agent despite its toxicities.
- Nephrotoxicity is a major dose-limiting side effect of amphotericin B.
Purpose of the Study:
- To detail the care of patients receiving intravenous amphotericin B.
- To emphasize strategies for preventing and managing amphotericin B-induced nephrotoxicity.
Main Methods:
- Review of current clinical practices for amphotericin B administration.
- Emphasis on pre-therapy assessment, ongoing monitoring, and post-therapy evaluation.
- Discussion of etiological factors, clinical signs, and symptoms of nephrotoxicity.
Main Results:
- Nephrotoxicity is the most serious and dose-limiting toxicity associated with amphotericin B.
- Proactive patient assessment and monitoring are crucial for mitigating renal damage.
- Understanding the mechanisms and manifestations of nephrotoxicity is essential for effective management.
Conclusions:
- Optimal patient care necessitates a thorough understanding of amphotericin B nephrotoxicity.
- Clinicians must be adept at identifying and managing the signs and symptoms of renal impairment.
- Implementing preventive interventions is imperative for safe and effective amphotericin B therapy.
