Evaluation of Sarcopenia and Related Factors in Patients Diagnosed With Psoriatic Arthritis

Evaluation of Sarcopenia and Related Factors in Patients Diagnosed With Psoriatic Arthritis

The purpose of the study is identify the prevalence of sarcopenia and its associated factors in patients with psoriatic arthritis. Furthermore, we aimed to investigate the predictive contribution of USG in diagnosing sarcopenia by assessing the thickness of the rectus femoris, vastus intermedius, and quadriceps muscles in patients with psoriatic arthritis.

After being informed about study and potential risk, all patient and giving written informed consent will undergo screnneing determite eligibility for study entire. Participants who agree to take part in the study and sign the informed consent form will be divided into two groups: patients and healthy volunteers. The patients will undergo a rheumatological examination, and sarcopenia screening will be conducted for both groups. Additionally, the quadriceps muscle thickness of both groups will be measured.
