OBJECTIVE: The purpose of this study was to investigate renal function in patients with brucellosis before and at the end of gentamicin therapy. To ensure the safety of therapeutic doses of gentamicin, renal functions in brucellosis patients were monitored regarding drug serum levels and check for early detection biomarkers of nephrotoxicity.
METHODS: In this cross-sectional study, 41 patients (25 men and 16 women, aged over 15 years) were included, with confirmed acute brucellosis that referred to Brucellosis Research Center in Hamadan, west of Iran between March 2018 to February 2019. At baseline before treatment (first step) and 7 days after gentamicin administration (second step), serum uric acid, blood urea nitrogen (BUN), serum and urine creatinine, erythrocyte sedimentation rate (ESR), quantitative C-reactive protein (CRP) and urinary β2-microglobulin (β2M) were measured. Gentamycin serum level due to the highest risk of nephrotoxicity with this drug in aminoglycoside class was also checked by HPLC method. The data were analyzed using SPSS version 22.
RESULTS: The mean urinary β 2M level, serum and urinary creatinine, uric acid, BUN, and quantitative CRP levels in the first step and second step, there were no statistical differences between the two steps. There was a correlation between urinary creatinine and ESR. In addition, a positive correlation was found between urinary β2M and serum gentamicin level. ESR levels have been significantly reduced in the patients after the treatment compared to before it.
CONCLUSION: Our findings confirm that gentamicin is safe at the dose of 5 mg/kg/day for one week intravenously in brucellosis patients.
