DKK-1 in psoriatic arthritis: Correlation with disease activity and enthesopathy.

Background: Psoriatic arthritis (PsA) is a complex inflammatory disease with varied clinical characteristics. A pathognomonic characteristic of PsA is enthesitis. Entheseal inflammation ultimately leads to the production of new bone (enthesophytes).

Development of outcome measures for giant cell arteritis for use in clinical trials and standard practice.

Background: Developments in outcome measures in the rheumatic diseases are promoted by the development of successful treatments. Giant cell arteritis (GCA) is a multifaceted disorder and, therefore, measurement of multiple outcomes is relevant to this illness. It is a privilege to analyze and monitor/transfer long-term patients' management outcomes particularly if the same outcomes are used in practice and in trials.

Serum interleukin-23 levels: relation to depression, anxiety, and disease activity in psoriatic arthritis patients.

Objectives: Assessment of serum levels of IL-23 in PsA patients and its correlation with depression, anxiety, and disease activity.

Methods: Eighty psoriatic arthritis (PsA) patients and eighty healthy volunteers matched for age and gender were included in this observational case-control study. All participants suspected to detailed history, clinical assessment, PsA activity using Disease Activity Index for Psoriatic Arthritis (DAPSA) score, the severity and extent of psoriasis was assessed by the Psoriasis Area and Severity Index (PASI), and ultrasonographic assessments of the entheses were examined according to the Madrid Sonographic Enthesitis Index (MASEI).
