RESUMO

Sjogren's syndrome (SS) is a chronic autoimmune connective tissue disease. Varying rates of system involvements may be seen in the course of the disease. Semaphorins has multifunctions in several physiological and pathological processes such as immune system regulation. The association of Semaphorin 3A (Sema3A) and Semaphorin 7A (Sema7A), which are immune semaphorins, with autoimmune diseases is interesting for researchers. We aimed to compare serum Sema3A and Sema7A levels between primary SS and control subjects, and investigated Sema3A and Sema7A levels in disease subgroups and associated system involvements. 50 consecutive primary SS patients and 40 healthy subjects followed in the Rheumatology clinic of Cumhuriyet University Medical Faculty between 2017 and 2018 were included in the study. Inclusion criteria of patients were diagnosis of primary SS according to the 2016 ACR/EULAR classification criteria. Serum Sema3A and Sema7A levels were measured by commercial ELISA kit. Both groups were similar in terms of age, gender, and body mass index. Serum Sema3A and Sema7A levels were significantly lower in SS than in the controls (p = 0.001 and p = 0.005, respectively). Serum Sema3A levels were significantly lower in patients with renal involvement than in patients without (p = 0.03). Sema3A and Sema7A may play a role in the etiopathogenesis of SS and may be a potential serological marker for the diagnosis of SS and may be a target for treatment.
