RESUMO
BACKGROUND: Limited studies have been conducted on patients with renal function recovery regarding severe leptospirosis. The purpose of this study is to evaluate the effectiveness of N-acetylcysteine (NAC) in accelerating the reduction of serum creatinine in patients with leptospirosis. PATIENTS AND METHODS: This is a clinical trial study involving 64 patients with leptospirosis, with microscopic agglutination tests used to confirm the diagnosis of acute kidney injury. NAC was given to patients with a glomerular filtration rate of less than 60 ml/min at 1200 mg every 12 h, and it lasted for 48 h. Next, 32 patients were measured and the relationship between the length of hospitalization, age, and sex was also examined. Additionally, the two groups of case and control were compared in terms of the rate of decrease in serum creatinine level in three different time periods. The Shapro-Wilk test was used to investigate the distribution of data. RESULTS: No significant differences were observed in the decrease in serum creatinine level on the first, third, and seventh days of hospitalization and also in the use of NAC between the case and control groups (P = 0.255). In addition, the use of NAC had no significant effect on reducing the length of hospitalization (P = 0.067). CONCLUSION: Recovery of acute kidney injury following leptospirosis and drugs that accelerate the healing process in these patients require further studies with greater sample size and longer follow-up time.
