A Case Series of Acute Kidney Injury During Anti-tuberculosis Treatment
Abstract
Objective The standard anti-tuberculosis (TB) regimen occasionally causes acute kidney injury (AKI). The major etiology is rifampicin-induced acute interstitial nephritis. However, the standard management of AKI induced by anti-TB drugs has yet to be established. Methods We retrospectively reviewed patients with TB who developed AKI after starting standard anti-TB treatment between 2006 and 2016 at a single TB center. The clinical characteristics and the management are described. Results Among 1,430 patients with active TB, 15 (1.01%) developed AKI. The mean age (standard deviation) was 61 years (18). The median (interquartile range) time to AKI development was 45 days (21-54 days). The median serum creatinine level before anti-TB treatment was 0.7 mg/dL (0.5-1.4 mg/dL), whereas the median peak serum creatinine level after AKI onset was 4.0 mg/dL (3.08-5.12 mg/dL). Five patients (33.3%) were pathologically confirmed as having acute interstitial nephritis (AIN), and 7 patients (46.7%) had a clinical diagnosis of the disease. All anti-TB drugs were stopped, and steroids were administered to 5 (100%) patients with pathologically confirmed AIN and 3 (42.8%) patients with clinically diagnosed AIN. The renal function was normalized in 12 patients (80.0%) after restarting anti-TB treatment without rifampicin (n=12) or isoniazid (n=1). Two patients died due to severe renal failure after restarting rifampicin. Conclusion Rifampicin is the leading cause of AKI. Levofloxacin may be an…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 1,430 participants or records.
