Factors Affecting the Recovery of Renal Function in Geriatric Multiple Myeloma Patients after Hemodialysis

Multiple myeloma (MM) is a disease of the elderly. Renal failure is a common complication in MM. In this study, we evaluated clinical and laboratory parameters that might contribute to the recovery of renal function in geriatric MM patients. Twenty-five geriatric patients aged >65 years were retrospectively compared with 20 patients aged <65 years with a diagnosis of MM and renal failure between October 2016 and October 2019. Variables that might be associated with the discontinuation of dialysis in these patients were examined in the 6 months of follow-up after the diagnosis. Among the geriatric patients aged >65 years, 100% remained on regular hemodialysis (HD) at the end of the follow-up period in contrast to eight patients (40%) in the younger group, and this was statistically significant P = 0.001. We have noticed that geriatric patients who required maintenance HD had lower mean hemoglobin concentrations (P = 0.02), and higher mean serum calcium (P = 0.03). Other factors were statistically insignificant. Our study showed that age of >65 years, hemoglobin levels, and serum calcium were significantly different between the group who recovered from renal failure and those who required a continuation of HD, but none was an independent prognostic factor for predicting the probability of recovery from severe renal failure and discontinuation of HD in both groups studied.
