@Article{, title={A STUDY OF LEPTIN & LIPID PROFILE IN A SAMPLE OF IRAQIPATIENTS WITH KNEE OSTEOARTHRITIS.}, author={Zina H. Abdul-Qahar and Mohammed H. Alosami and Kismat M. Turki}, journal={Journal of the Faculty of Medicine Baghdad مجلة كلية الطب}, volume={50}, number={3}, pages={372-376}, year={2008}, abstract={Background: New data suggests that joint damage in Knee Osteoarthritis (KOA) may be
caused by systemic factors like adipose tissue products; Adipokines, which may provide a
metabolic link between obesity & KOA. Recently, one of the known adipokines named
LEPTIN has been linked to KOA because it can be detected in serum & synovial fluid of
patients with KOA.
Objective: To evaluate the contribution of Leptin & serum lipids to the pathophysiology of
Osteoarthritis in Iraqi patients with Knee OA.
Subjects& Methods: The study was carried on 90 subjects divided into four groups:
Knee Osteoarthritis cases group (n=60).
Control group (n=30).
Obese subjects group (n=60).
Non-obese subjects group (n=30).
KOA cases were diagnosed clinically whereas obesity was specified by BMI ≥25kg/m2. For
all subjects studied measurements of fasting serum leptin and lipid profile have been done.
Results: Mean serum leptin level was significantly higher in KOA cases compared to control
group (P<0.001), and higher in obese than non-obese subjects (P<0.001). Serum leptin level
also showed a strong positive correlation with BMI (r=0.501, P<0.01).
Conclusions: Leptin may play an important role in the pathogenesis of KOA. In addition
abnormal lipid profile and obesity are important risk factors for KOA.
