Abnormal bone remodelling and increased levels of macrophage inflammatory protein-1 alpha (MIP-1) in Waldenstr{\"o}m macroglobulinaemia
Serum levels of macrophage inflammatory protein-1 alpha (MIP-1 alpha)
and bone remodelling markers were evaluated in 38 patients with
Waldenstrom macroglobulinaemia (WM) and correlated with clinical and
laboratory variables. MIP-1 alpha was elevated in WM; untreated patients
had higher MIP-1 alpha levels than patients in remission or with active
disease after treatment. MIP-1 alpha correlated with increased bone
resorption, beta(2)-microglobulin and splenomegaly. Receptor activator
of nuclear factor-kappa B ligand serum levels were elevated in WM
patients; the subsequent increased bone resorption was balanced by a
comparable elevation of osteoprotegerin production and bone formation.
These findings may explain the absence of lytic lesions in WM patients
and suggest a potential role of MIP-1 alpha in WM
