Abstract:
Objective To study the role of bone turnover markers in multiple myeloma(MM)bone disease.Methods Thirty-eight MM patients were studied.Serum and urine samples were taken before,after 3 months and 6 months therapy.Serum samples of tartrate resistant acid phosphatage isoform-5b(sTRACP-5b),bonespesific alkaline phosphatase(sBAP),osteocslcin(sOC),urine samples of N-telopeptides of type Ⅰ collagen(NTX)were measured.Results Urine NTX concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in pleateum patients and controls.serum TRACP-5b concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in controls.There were no statistical significance compared with pleateum patients.Serum BAP concentrations were significantly lower than that in pleateum patients and controls.Serum OC concentrations were not statistically significant among the newly diagnosed patients,relapsed or refractory patients,pleateum patients and control.In newly diagnosed patients.urine NTX levels were significantly higher in stage Ⅲ than that in stage Ⅰ/Ⅱ,serum BAP levels were significantly lower in stage Ⅲ than that in stage Ⅰ/Ⅱ.There was a positive relationship between urine NTX and serum TRACP-5b in newly diagnosed patients.Urine NTX levels were significantly decreased,and serum BAP levels were significantly increased after 3 cycles effective therapy.There was no change in serum TRACP-5b and OC.Urine NTX and serum TRACP-5b were significantly diseased,serum BAP and OC were significantly increased after 6 cycles of effective therapy.But bone lesions on X-ray did not diminish at that time.Conclusion There is a closely relationship between bone turnover markers and bone lesions in MM.The bone turnover markers may be useful in monitoring MM progress and therapy.
