Similarities and differences between systemic juvenile idiopathic arthritis and adult-onset Still's disease: a multicenter Spanish study.

To describe the characteristics of systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD), compare their presentation and evolution, and analyse possible complication predictors. Multicenter study. Data were retrieved from a hospital-based study of patients with a diagnosis or suspected diagnosis of sJIA or AOSD according to the responsible physician and followed-up for at least one year.

Phenotyping by persistent inflammation in systemic sclerosis associated interstitial lung disease: a EUSTAR database analysis.

Background: Systemic sclerosis (SSc) is a heterogeneous disease with frequently associated interstitial lung disease (SSc-ILD). We aimed to determine the prognostic potential of phenotyping patients with SSc and SSc-ILD by inflammation and to describe disease trajectories stratified by inflammation and immunosuppressive treatment.

Methods: Patients from the European Scleroderma Trials and Research (EUSTAR) group cohort were allocated to persistent inflammatory, intermediate and non-inflammatory phenotypes if C-reactive protein (CRP) levels were ≥5 mg/L at ≥80%, at 20-80% and at <20% of visits, respectively.

Immunoglobulins in systemic sclerosis management. A large multicenter experience.

Objective: To analyze the effectiveness and safety of intravenous immunoglobulin (IVIG) given in routine care to patients with systemic sclerosis (SSc).

Methods: A retrospective multicenter observational study was conducted in SSc patients treated with IVIG. We collected data on epidemiological parameters and clinical outcomes.

Decreasing prevalence of chronic back pain in Catalonia. Analysis of the Catalan Health Survey.

Objectives: Chronic back pain is one of the main health problems reported by the adult population and its prevalence is influenced by different sociodemographic, work and lifestyle-related factors. The aim of this study was to describe the trend in the lifetime prevalence of chronic back pain in the adult Catalan population between 2011 and 2018 and its associated factors.

Study Design: Cross-sectional study.

Value of second-trimester uterine artery pulsatility index in pregnancies with systemic lupus erythematosus and/or antiphospholipid syndrome.

Objective: To assess the value of the second trimester mean pulsatility index of the uterine arteries (MPI-UtA) to predict adverse perinatal outcome (APO) in women with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS).

Methods: Pregnancies with either an SLE diagnosis or with primary APS controlled at our Hospital during a 10 years period were included. MPI-UtA was performed between 19-23 weeks' gestation.
