Aim: То investigate the serum levels of vitamin D in newly diagnosed patients with multiple myeloma.
Patients and methods: In this study we measured the serum levels of vitamin D in 37 patients (19 women, 18 men) at a median age of 68 years and a diagnosis of MM according to the International Myeloma Working Group (IMWG) criteria. The immunoassay tests used for the quantification of 25 (OH) - Vitamin D were original ELISA kits Immundiagnostic and the measurement was done before starting the treatment.
Results: Serum levels below the optimum (<30 ng/ml) were recorded in all 37 patients. The median value of vitamin D was 4.3±6.5 mg/ml, the maximum value measured was 24.7 mg/ml, which is below the lower limit of the reference value for deficiency.
Conclusions: In this study, we found extremely low serum vitamin D levels in most of the newly diagnosed MM patients.
