Evaluating standards of care in psoriatic arthritis of the QUANTUM project (qualitative initiative to improve outcomes): results of an accreditation project in Spain

In Spain, the QUANTUM project has been promoted to reduce variability in clinical practice and improve the care and quality of life of people with psoriatic arthritis (PsA) by accrediting PsA units throughout the Spanish national health system. To present the results of this approach which sought to ensure an optimum level of quality for patients with PsA. Descriptive analysis of the self-assessments that the PsA units have carried out assessing their degree of compliance with the quality standards established in the QUANTUM project grouped into four blocks: shortening time to diagnosis; optimizing disease management; improving multidisciplinary collaboration; and improving patient monitoring. A total of 41 PsA units were self-evaluated. They met 64.1% of the defined quality standards. Optimize disease management obtained a higher level of standards compliance (72%) and improve multidisciplinary collaboration the lesser (63.9%). Accessibility to the treatments available for PsA in all hospitals was guaranteed (100%). Appropriate diagnostic equipment is available (97.6%). Compliance with specific quality standards leads to detect actions that should be implemented: quality of life assessment (9.8%), locomotor system assessment (12.2%), physical examination data record (14.6%), periodic cardiovascular risk assessment (17.1%). The QUANTUM project results make it possible to visualise how to care for patients with PsA is being developed in Spain. Problems identified in recent multinational reports are also identified in Spain

Higher COVID-19 pneumonia risk associated with anti-IFN-α than with anti-IFN-ω auto-Abs in children

We found that 19 (10.4%) of 183 unvaccinated children hospitalized for COVID-19 pneumonia had autoantibodies (auto-Abs) neutralizing type I IFNs (IFN-alpha 2 in 10 patients: IFN-alpha 2 only in three, IFN-alpha 2 plus IFN-omega in five, and IFN-alpha 2, IFN-omega plus IFN-beta in two; IFN-omega only in nine patients). Seven children (3.8%) had Abs neutralizing at least 10 ng/ml of one IFN, whereas the other 12 (6.6%) had Abs neutralizing only 100 pg/ml. The auto-Abs neutralized both unglycosylated and glycosylated IFNs. We also detected auto-Abs neutralizing 100 pg/ml IFN-alpha 2 in 4 of 2,267 uninfected children (0.2%) and auto-Abs neutralizing IFN-omega in 45 children (2%). The odds ratios (ORs) for life-threatening COVID-19 pneumonia were, therefore, higher for auto-Abs neutralizing IFN-alpha 2 only (OR [95% CI] = 67.6 [5.7-9,196.6]) than for auto-Abs neutralizing IFN-. only (OR [95% CI] = 2.6 [1.2-5.3]). ORs were also higher for auto-Abs neutralizing high concentrations (OR [95% CI] = 12.9 [4.6-35.9]) than for those neutralizing low concentrations (OR [95% CI] = 5.5 [3.1-9.6]) of IFN-omega and/or IFN-alpha 2

Association of IL1Β (-511 A/C) and IL6 (-174 G > C) polymorphisms with higher disease activity and clinical pattern of psoriatic arthritis

The objective of this study is to analyze whether IL1β (-511G > A) and IL6 (-174 G > C) polymorphisms are associated with inflammatory activity, radiographic damage or clinical pattern of psoriatic arthritis (PsA). One hundred twenty-five patients classified as PsA according to the Classification of Psoriatic Arthritis (CASPAR) criteria were included. Patients were stratified according to their clinical pattern at inclusion as peripheral, axial, or mixed involvement. Disease activity in peripheral or mixed forms was measured using the number of swollen and tender joints, pain analog visual scale, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and disease activity score 28 (DAS28). Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was used for axial and mixed forms, as were pain visual analog scale, ESR and CRP. Radiographic damage was evaluated using a modified Sharp score and modified stoke ankylosing spondylitis spinal score (SASSSm). The polymorphisms for the promoter region of IL1β (-511 G/A) and IL-6 (-174 G/C) were analyzed. The G allele of IL1B (-511G/A) polymorphism was associated with higher peripheral joint disease activity (OR 3.13; p C) polymorphism presented a strong trend to be associated with peripheral forms (70.86 %) (OR 1.89; p < 0.03; CI 95 % 1.06–3.39, p-corrected 0.05). In addition, this allele showed a lower association with HLA-B27 (15.78 %) compared with C allele (28.57 %) (OR 0.469; p = 0.02; CI 95 % 0.238–0.923, p-corrected 0.03). This study suggests that the G allele polymorphism of IL1B (-511 A/C) is associated with higher peripheral joint disease activity. On the other hand, the IL6 (-174 G/C) polymorphism showed a strong trend to be associated with the peripheral pattern of PsA.This study was supported by a grant from the Fundación Española de Reumatología (to C. Montilla) and FIS PI PI13/01741.Peer Reviewe

Looking Into the New ASAS Classification Criteria for Axial Spondyloarthritis Through the Other Side of the Glass

© 2015, Springer Science+Business Media New York.The new concept of axial spondylitis (axSpA) and the Assessment of Spondyloarthritis International Society (ASAS) classification criteria for axSpA have induced new clinical research that has broadened our understanding of spondyloarthritis (SpA) and has had indeed a positive impact on earlier diagnosis and treatment of patients with axSpA who have not yet developed radiographic sacroiliitis. The primary goal of any valid classification criteria for any disease is to provide a homogeneous study population with a common etiopathogenesis, similar prognosis, and similar response to identical treatment. Without such a homogeneous study population, robust clinical and basic science research in any subtype of SpA is not possible. All criteria are dynamic concepts that need updating as our knowledge advances and our review of the ASAS classification criteria of axSpA indicates that complex multi-selection design and unclear (not mutually exclusive) definitions of the imaging and clinical arms of the criteria results in patient heterogeneity across study populations. Therefore, there is a need to improve the validity of the ASAS criteria for axSpA. It is our opinion that in the meantime, the clinically well-established entity of AS, as defined by the modified New York (mNY) criteria, should be preserved for the most accurate comparison of the new research studies with those conducted over the last three decades, and that the use of the ASAS criteria should be restricted to patients with nr-axSpA, who are not recognized by the mNY criteria
