Impact of hyperuricaemia on patients with psoriatic arthritis treated with secukinumab in the FUTURE 2-5 and MAXIMISE studies.

Objectives: Patients with psoriatic arthritis (PsA) are at a significantly increased risk of hyperuricaemia and development of gout, and those with hyperuricaemia have been found to respond poorly to PsA treatment and have more peripheral and destructive joint damage. We present a comprehensive post hoc analysis using pooled data from the FUTURE 2-5 studies and the MAXIMISE study to further evaluate the impact of hyperuricaemia on clinical presentation/disease severity and response to secukinumab in patients with PsA.

Methods: Patients were stratified into two groups based on baseline serum uric acid (SUA) level (threshold of 360 µmol/L).

Examining the biological pathways underlying clinical heterogeneity in Sjogren's syndrome: proteomic and network analysis.

Objectives: Stratification approaches are vital to address clinical heterogeneity in Sjogren's syndrome (SS). We previously described that the Newcastle Sjogren's Stratification Tool (NSST) identified four distinct clinical subtypes of SS. We performed proteomic and network analysis to analyse the underlying pathobiology and highlight potential therapeutic targets for different SS subtypes.

Association Between Bruton's Tyrosine Kinase Gene Overexpression and Risk of Lymphoma in Primary Sjögren's Syndrome.

Objective: We undertook this study to analyze whole blood gene expression and to investigate the role of B cell genes in primary Sjögren's syndrome-related non-Hodgkin lymphoma (primary SS-NHL).

Methods: Peripheral whole blood samples were collected from 345 well-phenotyped patients with primary SS enrolled in the prospective Assessment of Systemic Signs and Evolution in Sjögren's Syndrome (ASSESS) cohort. Transcriptomic analysis was performed using human Clariom S Arrays (Affymetrix).

[Which taxonomy for inflammatory diseases in rheumatology? The concept of Psout].

Clinical practice needs the identification of the patient disease. The physician has to rationalize symptoms allowing the recognition of a realistic entity and its classification in a reference nosology. Unlike other practices, the biomedical model uses scientific census methodology, from a tabular perspective to the definition of diseases.

Seasonal effect on fatigue, pain and dryness in primary Sjögren's syndrome.

Background: To assess the presence of a seasonal effect on fatigue, pain and dryness in primary Sjögren's syndrome (pSS).

Methods: Data (date; visual analogue scales (VAS) for pain, fatigue and dryness) were extracted from three randomised placebo-controlled trials (RCTs) evaluating infliximab (TRIPSS; n = 103 patients), hydroxychloroquine (JOQUER; n = 120 patients) and rituximab (TEARS; n = 120 patients) and from the 5-year follow-up of the ASSESS prospective cohort (n = 395 patients). Data were analysed at each visit for each patient, according to the day, the month of the year and the season.

At the crossroads of gout and psoriatic arthritis: "psout".

Psoriatic arthritis and gout are frequently encountered conditions sharing a number of common risk factors, which render their independent study difficult. Epidemiological studies have demonstrated a strong link between these diseases, suggesting the presence of underlying, intertwined pathophysiological mechanisms that currently remain unknown. Indeed, sodium urate crystals could play a pathogenic role in psoriasis and psoriatic arthritis.
