Psoriasis Symptom Inventory (PSI) as a patient-reported outcome in mild psoriasis: Real life data from a large psoriatic arthritis registry

Objective: Our aim is to test the validity of the Psoriasis Symptom Inventory (PSI), a patient-reported outcome, to assess the psoriasis severity within the scope of rheumatology. Methods: Within the PsA international database (PSART-ID), 571 patients had PSI, while 322 of these also showed body surface area (BSA). Correlations between PSI, BSA, and other patient- and physician-reported outcomes were investigated. Results: There was a good correlation between PSI and BSA (r=0.546, p<0.001), which was even higher for mild psoriasis (BSA<3 (n=164): T-0.608, p<0.001). PSI significantly correlated with fatigue, pain, and patient and physician global parameters (p<0.001). Conclusion: PSI has a good correlation with other patient- and physician-reported outcomes, and our findings support its use in rheumatology practice

The Psoriatic Arthritis Registry of Turkey: results of a multicentre registry on 1081 patients

Objective. The aim was to assess the characteristics of PsA, find out how well the disease is controlled in real life, demonstrate the treatments and identify the unmet needs. Methods. The PsA registry of Turkey is a multicentre Web-based registry established in 2014 and including 32 rheumatology centres. Detailed data regarding demographics for skin and joint disease, disease activity assessments and treatment choices were collected. Results. One thousand and eighty-one patients (64.7% women) with a mean (S.D.) PsA duration of 5.8 (6.7) years were enrolled. The most frequent type of PsA was polyarticular [437 (40.5%)], followed by oligoarticular [407 (37.7%)] and axial disease [372 (34.4%)]. The mean (S.D.) swollen and tender joint counts were 1.7 (3) and 3.6 (4.8), respectively. Of these patients, 38.6% were on conventional synthetic DMARD monotherapy, 7.1% were on anti-TNF monotherapy, and 22.5% were using anti-TNF plus conventional synthetic DMARD combinations. According to DAS28, 86 (12.4%) patients had high and 105 (15.2%) had moderate disease activity. Low disease activity was achieved in 317 (45.7%) patients, and 185 (26.7%) were in remission. Minimal disease activity data could be calculated in 247 patients, 105 of whom (42.5%) had minimal disease activity. The major differences among sexes were that women were older and had less frequent axial disease, more fatigue, higher HAQ scores and less remission. Conclusion. The PsA registry of Turkey had similarities with previously published registries, supporting its external validity. The finding that women had more fatigue and worse functioning as well as the high percentage of active disease state highlight the unmet need in treatment of PsA

Evaluation of periostin and factors associated with new bone formation in ankylosing spondylitis: Periostin may be associated with the Wnt pathway

Objective: Periostin has been shown to be involved in bone anabolism through the regulation of Wnt-beta-catenin signaling. It may be one of the pathogenic mechanisms in syndesmophyte formation in ankylosing spondylitis (AS). The aim of this study was to evaluate serum periostin levels in patients with AS and to assess relationships among biomarkers of bone formation and periostin in disease outcomes, particularly radiographic changes. Methods: Ninety-seven consecutive AS patients (78% male) and 48 healthy controls (75% male) were included in the study. Serum periostin, dickkopf-1 (DKK-1), sclerostin and vascular endothelial growth factor (VEGF) levels were measured using commercially available enzyme-linked immunosorbent assay kits. Disease-related characteristics of patients were assessed using Ankylosing spondylitis disease activity score - C-reactive protein (ASDAS-CRP), Bath AS Disease Activity Index, Bath AS Functional Index and Bath AS metrology index. Radiographs were scored using the modified New York criteria and modified Stokes AS spinal score (mSASSS). Results: Compared with control subjects, patients with AS had significantly lower serum levels of periostin (P < 0.001) and sclerostin (P < 0.001), but higher serum levels of VEGF (P < 0.001) and high-sensitivity CRP (P < 0.001). Serum periostin (P = 0.005) and sclerostin levels (P = 0.016) were significantly lower in patients with very high disease activity according to ASDAS-CRP. Current age (P = 0.009), age at symptom onset (P = 0.021) and hip joint involvement (P = 0.012) were independently associated with the development of syndesmophyte, in contrast to biomarkers of bone metabolism that we evaluated. Conclusion: Our results suggest that periostin is down-regulated in AS patients with highly active disease and may contribute to disease pathogenesis through an interaction with Wnt signaling

Large joint and lower extremity involvement have higher impact on disease outcomes in oligoarticular psoriatic arthritis

Objective Joints with different sizes and anatomical locations can be affected in psoriatic arthritis (PsA). Our aim was to explore the effect of different joint patterns on patient-reported outcomes (PROs) in patients with mono-oligoarthritis. Methods Within PsArt-ID (Psoriatic Arthritis- International Database), 387/1670 patients who had mono-oligoarthritis (1-4 tender and swollen joints) were enrolled in cross-sectional assessment. The joints were categorized according to their size (small/large) and location (upper/lower extremity) and PROs, physician global assessment and C-reactive protein (CRP) were compared. Analysis was made by categorizing according to joint counts (1-2 joints/ 3-4 joints). Results The mean age (SD) was 46.9 (14.24) with a mean (SD) PsA duration of 3.93 (6.03) years. Within patients with 1-2 involved joints (n = 302), size of the joints only had an impact on CRP values with large joints having higher CRP (P = .005), similar to lower extremity involvement (P = .004). PROs were similar regardless of size or location if 1-2 joints were inflamed. Within patients with 3-4 involved joints (n = 85), patient global assessment (PGA), pain, fatigue and physician global assessment were higher in the group with large joints. Similarly, PGA, pain, and physician global assessment were higher in patients with lower extremity involvement as well as higher CRP values. Conclusion For PsA patients with 3-4 joints involved, lower extremity and large joints are associated with poorer outcomes with worse PROs, physician global assessment, and higher CRP. The size and anatomical location of the joints are less important for patients with 1-2 joints in terms of the PROs.Union Chimique Belge (UCB) ; Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK
