OBJECTIVE: To investigate sickness benefits following delivery in mothers with systemic lupus erythematosus (SLE) and mothers without SLE. METHOD: SLE and non-SLE mothers, matched by age and month of delivery, with a singleton liveborn (2004-2008), were identified from the Swedish Lupus Linkage cohort. Work loss (sum of sick leave and disability pension) was studied from 1 year prenatally to 3 years postpartum. Adjusted logistic regression models of covariates associated with > 30 days of work loss in the first and second years postpartum were estimated in SLE mothers...

OBJECTIVE: Predictors of arthritis development in patients with anti-citrullinated protein antibodies (ACPAs) and musculoskeletal symptoms are needed for risk stratification and to improve clinical outcomes. The aim of this study was to assess the relationship between serum protein electrophoresis (SPE) constituents and the development of clinical arthritis in ACPA-positive patients with musculoskeletal pain. METHOD: We prospectively followed 82 ACPA-positive patients with musculoskeletal pain but no baseline arthritis during a median of 72 months (interquartile range 57-81 months)...

OBJECTIVES: Screening tools are needed to help to identify psoriatic arthritis in patients with psoriasis. The Psoriatic arthritis UnclutteRed screening Evaluation (PURE-4) questionnaire was developed for this purpose and has been shown to perform very well. The aim of this study was to translate and culturally adapt the PURE-4 scale into the Danish language. METHOD: The translational process followed the guidelines provided by the Mapi Research Trust, which include the following steps: forward translation, backward translation, cognitive interviews, and proofreading...

OBJECTIVES: To assess sleep quality, and its associations with physical function, cardiorespiratory fitness, and spinal mobility, in axial spondyloarthritis (axSpA) patients. METHOD: Baseline data from the Exercise for Spondyloarthritis trial were used. Assessments included [Pittsburgh Sleep Quality Index (PSQI), 0-21, 21 = worst], performance-based physical function [Ankylosing Spondylitis Performance Index (ASPI), seconds, higher = worse], patient-reported physical function [Bath Ankylosing Spondylitis Functional Index (BASFI), 0-10, 10 = worst], cardiorespiratory fitness [peak oxygen uptake (<mml:math xmlns:mml="https://www...

OBJECTIVE: The optimal strategy for difficult-to-treat (D2T) rheumatoid arthritis (RA) has not been identified, and the ultrasound characteristics of D2T RA have not been reported. We investigated the clinical characteristics and factors contributing to the outcome in D2T RA in a multicentre RA ultrasound observational cohort. METHOD: We reviewed 307 Japanese patients diagnosed with RA who underwent treatment with biological and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs)...

OBJECTIVE: While considerable focus has been placed on pain due to inflammation in psoriatic arthritis (PsA), less is reported on pain despite inflammation control. Here, we aimed to investigate the occurrence/predictors of persistent pain, including non-inflammatory components, after starting anti-tumour necrosis factor (anti-TNF) therapy. METHOD: Bionaïve PsA patients starting a first anti-TNF therapy 2004-2010 were identified (South Swedish Arthritis Treatment Group register; N = 351)...

OBJECTIVE: To investigate the determinants of hand strength in patients with hand osteoarthritis (OA). METHOD: Pinch and cylinder grip strength were measured in 527 patients with hand OA diagnosed by their treating rheumatologist from the Hand OSTeoArthritis in Secondary care (HOSTAS) study. Radiographs of hands (22 joints) were scored 0-3 (scaphotrapeziotrapezoid and first interphalangeal joints 0-1) on osteophytes and joint space narrowing following the Osteoarthritis Research Society International atlas...

OBJECTIVE: Pulmonary disease is a major cause of excess mortality among patients with rheumatoid arthritis (RA). Interstitial lung disease (ILD) is a feared complication, but the benefit of screening is unknown. The aim of this study was to assess the frequency of pulmonary disease, including ILD, in early RA. METHOD: Patients with newly diagnosed RA were recruited prospectively at a single centre and underwent systematic pulmonary function tests (PFTs) and computed tomography (CT) scans at inclusion and after two years...
