Rifampicin-Induced Nephrotoxicity in a Tuberculosis Patient: Treatment Dilemma?

Area of Science:

• Nephrology
• Infectious Diseases
• Pharmacology

Background:

• Rifampicin is a crucial antibiotic for treating tuberculosis.
• Acute kidney injury (AKI) is a potential adverse effect of rifampicin.
• Diagnosis of rifampicin-induced AKI is typically clinical.

Purpose of the Study:

• To report a case of acute tubulointerstitial nephritis caused by rifampicin.
• To illustrate the clinical presentation and diagnosis of drug-induced kidney injury.
• To emphasize the importance of considering rifampicin as a cause of AKI.

Main Methods:

• Case report presentation.
• Review of clinical history and laboratory findings.
• Discussion of differential diagnoses for AKI in tuberculosis patients.

Main Results:

• A patient undergoing treatment for pulmonary tuberculosis developed acute tubulointerstitial nephritis.
• The renal impairment was attributed to rifampicin, a component of the tuberculosis treatment regimen.
• Symptoms of kidney injury appeared several weeks after initiating rifampicin therapy.

Conclusions:

• Rifampicin can precipitate acute kidney injury.
• Renal impairment associated with rifampicin may manifest weeks after drug initiation.
• Clinicians should maintain a high index of suspicion for drug-induced AKI in patients on rifampicin.
