ABSTRACT
BACKGROUND: This study sought to examine the use of glutathione combined with mecobalamin in the prevention and treatment peripheral neuropathy (PN) in multiple myeloma (MM) patients, observe its effectiveness and safety, and explore the risk factors and prognostic factors of chemotherapy-induced peripheral neuropathy (CIPN).
METHODS: Patients in the study group were administered 2.4 g of glutathione intravenously once daily 2-3 days before chemotherapy, combined with 500 µg of mecobalamin administered intravenously once every other day until the end of the chemotherapy cycle. Patients who did not use this regimen were selected as a control group. Differences in adverse reactions, treatment efficiency, progression-free survival (PFS), and overall survival (OS) between the two groups were retrospectively analyzed. PFS and OS curves were plotted using the Kaplan-Meier method. The univariate analysis rates were compared using the χ2 test. The multivariate analysis was performed by a logistic regression analysis. The proportional hazard regression model was used for the univariate and multivariate proportional hazards model analyses.
RESULTS: The incidence of PN, especially grade 2 and 3 PN, was more decreased in the study group than the control group. The history of diabetes (P=0.032) and the method of bortezomib injection (P=0.043) was found to affect the PN grade. The multivariate logistic regression analysis showed that diabetes was an independent risk factor of PN in MM patients [odds ratio (OR) =3.484, P=0.020]. The Proportional hazards model multivariate analysis showed that extramedullary disease (EMD) [hazard ratio (HR) =2.373, P=0.006] and elevated lactic dehydrogenase (LDH) (HR =1.934, P=0.009) were independent prognostic factors for MM patients.
CONCLUSIONS: Glutathione combined with mecobalamin significantly reduced the incidence and severity of CIPN in MM patients, and did not increase the adverse reactions of patients with MM. Diabetes and bortezomib intravenously increased the incidence and severity of PN in patients with MM.
