Abstract
Introduction: Tendinopathy is a pathology of tendons of multifactorial origin displayed clinically as chronic degenerative tissue resulting in dysfunction and painful musculoskeletal system. Genetic implications in tendinopathy are not fully elucidated. Haptoglobin (Hp) polymorphism has been investigated for potential role in several diseases such as cardiovascular diseases. This study aims at investigating Hp polymorphism potential association with chronic tendinopathy in Jordan. Materials and Methods: A hospital-based case-control study, of 101 patients diagnosed with chronic tendinopathy and 104 age and gender matched controls, was employed and Hpphenotypes distributions were determined using Sodium Dodecyl Sulphate Polyacrylamide gel electrophoresis technique. Results: showed a significant association between tendinopathy cases and controls in relation to Hpphenotypes frequencies (Fisher’s Exact Test, [Formula: see text]). Odd ratios showed that the odds of tendinopathy cases in Hp2.1 group were reduced while odds in Hp2.2 and Hp1.1 were increased by 3.22 and 7.34 times, respectively, as likely compared to the controls. Conclusion: Results suggested that Hppolymorphism might play a role in chronic tendinopathy genesis.
