Objectives: The genetic contribution to psoriatic disease is substantial with a dominating influence of the HLA region. The profile of HLA class I genotypes likely contributes to shaping clinical phenotypes. Herein we aimed to explore such genotypes in cohorts of closely characterised subsets of psoriatic disease with special focus on psoriatic arthritis mutilans (PAM), a severe and rare form of psoriatic arthritis (PsA).

Methods: Cohorts of patients with the diagnosis of psoriasis vulgaris with or without arthritis (n=1217), psoriasis without arthritis (n=534), psoriatic arthritis without mutilating disease (n=337) and psoriatic arthritis mutilans (n=63) were collected and genotyped for HLA class I and II genes, with standardised methodologies. Cases were compared with a healthy control population (n=2468). Case-only and case-control association tests were performed to address the hypothesis of genetic contribution to clinical phenotypes.

Results: The presence of HLA-B*27 was strikingly increased in PAM (45%) compared with PsA without mutilating disease (13%) and with healthy controls (13%). However, within the PAM population, HLA-B*27 did not correlate with clinical markers such as number of mutilating joints, radiographic scoring, disease duration and age of disease onset.

Conclusions: HLA-B*27 emerges as an important genotype marker for PAM.

Objective: In China, Chinese herbal medicines (CHMs) have been widely used in the treatment of psoriatic arthritis (PsA), showing great therapeutic effects in clinical practice. However, due to the great heterogeneity of PsA and the diversity of CHM combination patterns, there is little high-level evidence-based medical research on the treatment of PsA with CHMs. This study aims to explore the beneficial effects of CHMs on the immune inflammation in PsA and its specific mechanism.

Objectives: To explore thresholds for the Psoriatic Arthritis (PsA) Impact of Disease questionnaire (PsAID12) score against disease activity measures in an observational setting, in patients with PsA.

Methods: The baseline data from the ReFlaP observational, prospective, multicentre and international study was used (NCT03119805). Cutoffs for PsAID12 were determined against disease activity scores, defining disease impact states (ie remission, low impact, moderate impact and high impact).

Growing evidence suggests that serotonin is an important mediator in the cross-talk between immune and bone cells, playing a role in the pathogenesis of various types of inflammatory arthritis (IA). However, the relationship between circulating serotonin and different outcomes in three most prevalent IA - rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA), remains limited and requires further investigation. This study was performed to evaluate variations in serotonin serum levels among RA, PsA, and axSpA and to explore the utility of this biochemical marker in the assessment of disease activity and health status measurements provided by the Multi-Dimensional Health Assessment Questionnaire (MDHAQ).

Autoimmune enteritis (AIE) is a rare inflammatory condition with intractable diarrhea and malnutrition. Most cases are diagnosed during infancy, but rare adult-onset cases can occur. We present a male patient in his 60s with a history of psoriasis and psoriatic arthritis on etanercept who developed refractory and intractable diarrhea and malnutrition.
