Abstract

Background: Psoriasis is a multifactorial and inflammatory chronic skin disease indicated with T-cell-mediated keratinocyte hyper-proliferation. Demographic, epidemiological (family, twin), serological, and genetic studies have clearly demonstrated that psoriasis is a polygenic and multifactorial disease.

Aim: The objectives of the study are; to determine the prevalence of the polymorphisms of FAS (Fas cell surface receptor gene) -671 A>G (rs:1800682) and FASLG (Fas ligand gene) -844 T>C (rs:763110), to investigate the serum levels of sFas and sFasL, and also to discover any relationship between gene polymorphisms and serum levels in psoriatic patients.

Material and Methods: 50 treated and 69 untreated patients, and 140 healthy controls were included in the study. Polymorphisms were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The serum levels were measured in randomly selected treated (39) and untreated (40) patients, also in 84 healthy controls using micro-ELISA technique.

Results: There was no statistical difference between polymorphisms in the patient and control groups. However, sFas and sFasL levels in both treated and untreated patients were higher than that of the controls.

Conclusion: The investigated FAS and FASLG polymorphisms were not found to be directly associated with the psoriasis. Elevated sFas and sFasL levels in psoriatic patients showed that these factors may possess a significant role in the pathogenesis of psoriasis.
