The Prevalence and Incidence of Axial and Peripheral Spondyloarthritis in Inflammatory Bowel Disease: A Systematic Review and Meta-analysis.

Background And Aims: Inflammatory bowel disease [IBD] is a chronic disease which affects up to 0.5% of the population. Various extraintestinal manifestations occur, among which are rheumatic manifestations, grouped together under the name spondyloarthritis.

Performance of screening tools for psoriatic arthritis: a cross-sectional study in primary care.

Objective: . To compare the screening performance of the Psoriasis Epidemiology Screening Tool (PEST), Psoriatic Arthritis Screening and Evaluation (PASE) and Early Arthritis for Psoriatic Patients (EARP) questionnaires for detecting PsA among psoriasis patients in a primary care setting.

Methods: In a cross-sectional study, 473 primary care psoriasis patients at risk for PsA completed the PEST, PASE and EARP questionnaires and were clinically evaluated by a trained research nurse.

Adding ultrasound to clinical examination reduced frequency of enthesitis in primary care psoriasis patients with musculoskeletal complaints.

Objectives: Part of the psoriasis patients with musculoskeletal complaints will have inflammation of the entheses. Entheseal inflammation is difficult to assess by clinical examination only. Therefore, we aimed to determine the frequency of clinically relevant ultrasound inflammation at the most commonly assessed entheses (MASEI; Madrid Sonographic Enthesis Index) in primary care psoriasis patients with one or more tender entheses.

Prevalence of Psoriatic Arthritis in Primary Care Patients With Psoriasis.

Objective: To estimate the prevalence of psoriatic arthritis (PsA) in primary care patients diagnosed as having psoriasis and to estimate the prevalence of musculoskeletal symptoms in psoriasis patients in primary care.

Methods: We conducted a cross-sectional study in adult primary care patients with psoriasis. Responding patients reporting pain in joints, entheses, or the lower back were interviewed by telephone to determine eligibility and, if eligible, were invited for clinical evaluation.
