	abstract = {The cause of the polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder and skin changes (POEMS) syndrome is currently unknown, but increased levels of vascular endothelial growth factor (VEGF) appear to play a pathogenetic role. Osteosclerotic bone lesions are a characteristic finding in POEMS, but there are no data about the specific role of various molecules that control bone remodeling in patients with POEMS. Serum levels of angiogenic cytokines (VEGF, angiogenin, angiopoietin-2, and basic fibroblast growth factor) along with a series of bone remodeling indices (C-telopeptide of type I collagen, bone-alkaline phosphatase [bALP], osteocalcin [OC], soluble receptor activator of nuclear factor-κB ligand [RANKL], osteoprotegerin [OPG], and macrophage inflammatory protein-1α) were measured in 2 patients with POEMS before and after high-dose therapy (HDT) with autologous stem cell transplantation and in age- and sex-matched controls. Increased VEGF levels before HDT were reduced significantly after treatment, although levels of the other angiogenetic factors did not differ from that of controls and were less influenced by HDT. Serum RANKL levels were increased before HDT, whereas OPG levels were within the levels of healthy controls, resulting in an abnormal soluble RANKL to OPG ratio. Levels of bone resorption markers (C-telopeptide of type I collagen) were very low or undetectable before HDT, although bALP and OC levels were similar to that of controls. After HDT, soluble RANKL levels decreased, OPG remained rather stable, bone resorption markers increased to levels of normal individuals, bALP levels were rather unchanged, and OC levels increased. Decreasing VEGF levels parallel clinical improvement, and the restoration of normal bone metabolism follows HDT.},
