Serum Prolidase Activity and the Role of Leptin in Osteomalacia

Overview

Evaluation of the change of serum Prolidase and Leptin values in the diagnosis and follow-up of osteomalacia and its clinical usability

Osteomalacia describes a bone disorder in adults that is usually caused by long-term vitamin D deficiency. Osteomalacia, a metabolic bone disease characterized by impaired mineralization of the bone matrix.Not a single laboratory finding is specific to osteomalacia.The relationship between collagen and prolidase activity has been observed during fibrotic processes, where an increase in prolidase activity is accompanied by an increase in tissue collagen deposition. It has also been suggested that serum activity is increased in metabolic bone diseases.Leptin is a 16 kDa peptide hormone. It is a member of the long chain helical cytokine family, which is mainly produced by fat cells and proportional to the size of the stored fat. Leptin affects bone remodeling by reducing the activity of osteoclasts and thus participates in the pathogenesis of osteoporosis. In the light of these studies, the investigators planned our study according to the clinical significance of serum prolidase activity in osteomalacia and the place of leptin in osteomalacia.
