Abstract
Introduction
This study aimed to investigate the renal safety of Zoledronic Acid (ZOL) in patients with osteoporosis (OP).
Methods
A total of 1379 patients (baseline estimated glomerular filtration rate, eGFR ≥ 60 mL/min/1.73 m2) with primary OP who received ZOL from January 2008 to October 2020 at our hospital were retrospectively analyzed. Baseline and the changes in renal function within 1 year following infusions were collected, the incidence of renal impairment (eGFR < 60 mL/min/1.73 m2 or a > 25% reduction in the eGFR from baseline) was noted and the risk factors were analyzed. Furthermore, the changes in renal function between a 3-year consecutive infusion and a single infusion of ZOL were compared.
Results
Renal impairment occurred in 8.05% of patients, who with a significantly higher age, Charlson Comorbidity Index (CCI), smoking history, combination of hypertension or diabetes mellitus and worse renal function indicators (all P < 0.05). Binary logistic regression analysis showed that higher CCI (≥5) or smoking history or the baseline eGFR <90 mL/min/1.73 m2 were the risk factors for renal impairment (all P < 0.05). Patients of 3-year continuous infusion group had a significantly greater drop in the eGFR levels than the single infusion group after 1 year of infusion(s) (P < 0.05).
Conclusion
Attention should be given to possible potential renal impairment following ZOL infusion in clinical practice for the management of OP, particularly in patients with higher CCI (≥5) or smoking history or the baseline eGFR <90 mL/min/1.73 m2. Continuous infusion of ZOL exerts a significant impact on renal function when compared to single infusion and intensive monitoring of renal function is necessary.
