Objectives
The aim of this study was to retrospectively evaluate the effect of plasmapheresis treatment concomitant with chemotherapy and the number of sessions on renal improvement and survival in patients with newly diagnosed multiple myeloma (MM) presenting with acute kidney injury (AKI).
Material and methods
Retrospective analysis was performed on 55 newly diagnosed MM patients who were presented with AKI to the Hematology Clinic of University of the Health Sciences Antalya Training and Research Hospital between 2013 and 2021.
Results
The study included 55 patients between 39 and 91 years of age and comprised 22 (40%) women and 33 (60%) men. Forty-eight (87.3%) patients were treated with plasmapheresis and chemotherapy. Based on the median number of plasmapheresis sessions, the patients were grouped as ≤ 3 and > 3. A significant difference was observed in both groups between the mean values of repeated measurements at the time of diagnosis, after completion of plasmapheresis treatment, and at 1 month of plasmapheresis, when statistics of differences were evaluated for urea, creatinine, estimated glomerular filtration rate (eGFR) (ml/min), total protein, albumin, and globulin (p < 0.05); however, there was no difference between these parameters and the number of plasmapheresis sessions. The 1.16 (0.56–2.38) fold higher risk of ex found in patients with ≤ 3 plasmapheresis sessions compared to those with > 3 was not statistically significant (p > 0.05).
Conclusion
It was observed that plasmapheresis is beneficial in the short term for renal recovery in the treatment of MM with AKI and that > 3 plasmapheresis sessions have no superior effectiveness in renal improvement or survival.
