No Relationship Between Blood Groups and Psoriatic arthritis

Abstract

Background: Psoriatic arthritis (PsA) is an inflammatory musculoskeletal disease. The exact causes of PsA have not been identified. ABO and Rh blood groups continue to be an area of interest for various diseases. In this study, we aimed to evaluate whether there is any difference in the distribution of ABO and Rh blood groups in PsA. Methods: 233 PsA patients (PsA group) consecutively referred to the adult rheumatology outpatient clinics of a tertiary care hospital of central Anatolia between January 2019 and June 2020 were enrolled. The blood groups of the PsA group were compared with the blood groups of 6280 individuals who tested before elective operations at the same hospital between 1 January 2019 and 31 June 2020 (Control Group). Fourteen of the control group were excluded due to the presence of psoriasis/PsA in their medical records. In addition, the blood groups of 38,416 people who voluntarily donated blood to the Turkish Red Crescent XXXX Blood Center between January 1, 2019 and July 1, 2020 (donor group) were compared with the blood groups of the control group. Results: There was no significant difference between the PsA patients and the control group in any blood group, both in women, men and also cumulatively. Conclusion: The result of the study shows there is no significant difference in the blood groups between patients with PsA and the control group.
