Background
Psoriasis is a common inflammatory skin disease with heterogeneous presentation. Up to 30% of individuals have severe disease with a greater surface area of skin involvement, co-morbidity burden and impact on quality of life. Prognostic biomarkers of psoriasis severity could improve allocation of clinical resources and enable earlier int...
Psoriasis is a common, debilitating immune-mediated skin disease. Genetic studies have identified biological mechanisms of psoriasis risk, including those targeted by effective therapies. However, the genetic liability to psoriasis is not fully explained by variation at robustly identified risk loci. To refine the genetic map of psoriasis susceptib...

Background
Patients (pts) with psoriatic arthritis (PsA) can potentially develop axial inflammation in the sacroiliac joints (SIJs) and/or spine. Although validated classification criteria exist for axial spondyloarthritis, established criteria for classifying axial PsA are lacking. STAR (NCT04929210), a Phase 4, multicenter, randomized, controlled...
Background
Oligoarticular psoriatic arthritis (PsA, ≤4 joints affected), although common, is understudied, as most clinical trials require patients (pts) to have ≥3 swollen and tender joints. The FOREMOST study (NCT03747939) is the first large, phase 4, multicenter, randomized, placebo (PBO)-controlled trial to demonstrate efficacy of apremilast (A...
Background
Most clinical trials of PsA exclude patients (pts) with early oligoarticular (oligo) disease and there is limited evidence to drive treatment decisions in this setting.

Background
Cranial neuropathies (CN) are a rare neuropsychiatric SLE (NPSLE) manifestation. Previous studies reported that antibodies to the kinesin family member 20B (KIF20B) (anti-KIF20B) protein were associated with idiopathic ataxia and CN. We assessed anti-KIF20B as a potential biomarker for NPSLE in an international SLE inception cohort.

Tyrosine kinase 2 (TYK2) is a member of the JAK kinase family of intracellular signalling molecules. By participating in signalling pathways downstream of type I interferons, IL-12, IL-23 and IL-10, TYK2 elicits a distinct set of immune events to JAK1, JAK2 and JAK3. TYK2 polymorphisms have been associated with susceptibility to various rheumatic d...

Background
Mesangial lupus nephritis is considered benign with minimal potential for developing advanced chronic kidney disease (CKD). However, some patients still develop advanced CKD and end-stage renal disease (ESRD). Our objective was to describe the factors associated with the development of CKD stage IV or worse in patients with LN II.

Background
Many SLE patients develop lupus nephritis (LN) and receive mycophenolate mofetil (MMF), a teratogenic drug. Guidelines recommend azathioprine (AZA) in SLE pregnancy without providing guidance on pharmacogenetic testing and therapeutic monitoring although these may help personalize therapy (e.g., identifying ‘shunters’, non-adherence). We...
Background
Lupus nephritis (LN) leads to end stage kidney disease (ESKD) in 17–33% after 10 years. The prevalence of chronic kidney disease stage IV (eGFR=15–29ml/min/1.73m2) is not known.
