Abstract:
Osteoarthritis (OA) is a biomechanical process whereby joints respond pathologically mechanical stress, resulting in cartilage degradation and changes in subchondral bone. It has many risk factors as known female gender, obesity, and aging. Vitamin D may exert its effect on OA through bone; its deficiency could impair the ability of bone to respond optimally to insults. Leptin is a peptide hormone secreted by adipocytes and plays an important role in regulation of body weight, its level more in obese subjects and female gender regardless of obesity, so it may play a metabolic link between obesity and osteoarthritis. So both vitamin deficiency and increase leptin level may be risk factors for osteoarthritis Objective : To examine the cross - sectional association of vitamin D and serum leptin levels in a sample of Iraqi female with knee osteoarthritis.Method : A total of 180 women divided into 2 groups 90 subjects the first group for vitamin D levels and 90 subjects the second group for serum leptin levels and each group further classified into patients and equal number of their matched healthy controls in age and sex.In each group osteoarthritis was diagnosed according to ACR criteria for osteoarthritis and their body mass index (BMI) classified according to WHO classification of BMI into 3 groups : normal weight, overweight, obese Radiological grading done according to kellegren and Laurence radiological classification for osteoarthritis. Both vitamin D and leptin levels were assessed using ELIZA method.The first group (vitamin D and osteoarthritis) mean vitamin D levels in cases (45cases) were (0.309_+0.641) compared to (0.2614_+0.386) in controls. So vitamin D deficiency is prevalent among cases and controls and its level was inversely associated with body mass index, the deficiency was more severe among female in obese and overweight than normal weight.Associations of vitamin D levels with radiological grading, cases with grade ||| and |\/ are more deficiency than grade ||.The second group (serum leptin level and osteoarthritis), leptin was significantly higher in cases compared to controls, the mean serum leptin was (52.41_+28.26) and (40.39_+ 25.67) respectively. Its level directly correlated with body mass index, higher levels in obese and overweight than normal weight subjects, the difference was significant among both cases and controls.Association of leptin levels with radiological grading, the mean serum leptin was higher in cases with grade ||| , |\/ than grade ||.Conclusion : Vitamin D deficiency was prevalent among middle age Iraqi women, so it is difficult to establish a clear association between vitamin D deficiency and osteoarthritis in this study, and the deficiency was more in women with higher body mass index.Serum leptin level was higher in osteoarthritis women than their matched controls, and its level directly associated with increased in body mass index
