Correlation of osteoprotegerin and sRANKL concentrations in serum and bone marrow of multiple myeloma patients.

Abstract

In 20% of MM patients, serum OPG levels are elevated, and this may be a compensative reaction related to increased bone destruction. There is not statistically significant relationship between sRANKL serum and BM levels and the main clinical and laboratory parameters of the disease. Determination of BM and the serum sRANKL/OPG ratio seems to have no clinical value.
