Comparison of Liver Health in Psoriatic Arthritis Patients Using Anti-TNF or Anti-IL17 Treatments

Psoriatic arthritis (PsA) is an inflammatory joint disease that can also affect the liver. Some medications used to treat PsA, such as biological agents (TNF-alpha inhibitors and IL-17 inhibitors), may influence liver health over the long term. This retrospective study aims to evaluate the presence and progression of liver fibrosis (scarring) and hepatic steatosis (fatty liver) in PsA patients treated with TNF-alpha inhibitors or IL-17 inhibitors.

The study includes PsA patients who have used biological medications continuously for at least 2 years. Patients' liver health will be assessed using non-invasive tests such as liver ultrasonography and validated biochemical scoring systems (FIB-4, APRI). The findings will be compared with PsA patients treated only with methotrexate (MTX), a commonly used medication known to affect liver health.

This study will help understand whether biological therapies (TNF or IL-17 inhibitors) have a positive or negative impact on liver health compared to traditional treatments (MTX) in patients with psoriatic arthritis.
