Key clinical point: In patients with psoriatic arthritis (PsA), the percentages of some T reg cell subgroups and the levels of T reg-related cytokines, such as transforming growth factor-beta (TGFβ), were decreased.
Major finding: Compared with control individuals without PsA, patients with PsA had a similar proportion of T reg cells ( P = .071), with no significant difference in the proportion of OKT8 + T reg cells ( P = .679) and significantly decreased CD4 + T reg cells (standardized mean difference [SMD] −1.501; P = .023). TGFβ levels were lower in patients with PsA vs healthy controls (SMD −2.199; P = .003).
Study details : Findings are from a meta-analysis of 12 studies including 525 patients with PsA and 414 control individuals.
