Management of Nail Disease in Patients With Psoriatic Arthritis: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.

OBJECTIVE: Nail psoriasis is common, impairs fine motor finger functioning, affects cosmesis, and is associated with a lower quality of life. This review updates the previous Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations for nail psoriasis. METHODS: This systematic literature review of the PubMed, MEDLINE, Embase, and Cochrane databases examined the updated evidence since the last GRAPPA nail psoriasis treatment recommendations published in 2014. Recommendations are based on preformed PICO (Patient/Population - Intervention - Comparison/Comparator - Outcome) questions formulated by an international group of dermatologists, rheumatologists, and patient panel members. Data from this literature review were evaluated in line with Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. RESULTS: Overall, there is insufficient evidence to make any recommendation for the use of topical corticosteroids, topical calcipotriol, topical tazarotene, topical cyclosporine, dimethyl fumarates/fumaric acid esters, phototherapy, and alitretinoin. There is a low strength of evidence to support the use of calcipotriol and corticosteroid preparations, topical tacrolimus, oral cyclosporine, oral methotrexate, intralesional corticosteroids, pulsed dye laser, acitretin, Janus kinase inhibitors, and apremilast. CONCLUSION: The highest strength of supporting evidence is for the recommendation of biologic agents including tumor necrosis factor inhibitors, and interleukin 12/23, 17, and 23 inhibitors.

Consensus terminology for preclinical phases of psoriatic arthritis for use in research studies: results from a Delphi consensus study.

The concept of psoriatic arthritis (PsA) prevention is gaining increased interest owing to the physical limitation, poor quality of life and low remission rates that are achieved with current therapies for PsA. The psoriasis-to-PsA transition offers a unique opportunity to identify individuals at increased risk of developing PsA and to implement preventive strategies. However, identifying individuals at increased risk of developing PsA is challenging as there is no consensus on how this population should be defined. This Consensus Statement puts forward recommended terminology from the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network (PPACMAN) for defining specific subgroups of individuals during the preclinical and early clinical phases of PsA to be used in research studies. Following a three-round Delphi process, consensus was reached for three terms and definitions: 'increased risk for PsA', 'psoriasis with asymptomatic synovio-entheseal imaging abnormalities' and 'psoriasis with musculoskeletal symptoms not explained by other diagnosis'. These terms and their definitions will enable improved identification and standardization of study populations in clinical research. In the future, as increasing evidence emerges regarding the molecular and clinical features of the psoriasis-to-PsA continuum, these terms and definitions will be further refined and updated.

Comparative safety of systemic immunomodulatory medications in adults with atopic dermatitis.

BACKGROUND: Severe atopic dermatitis (AD) is increasingly treated with systemic immunomodulatory drugs, yet their safety is unclear. OBJECTIVE: We evaluated the comparative risk of serious bacterial and opportunistic infections among patients with severe AD using systemic immunomodulatory medications in routine care. METHODS: In a population-based claims data study, we identified adult patients with AD who were treated with systemic drugs. The incidence of serious bacterial and opportunistic infections leading to hospitalization was computed by using International Classification of Disease diagnosis codes. Relative risks (RRs) were computed after 1-to-1 propensity score matching. RESULTS: Up to 232,611 patients with AD were eligible. The incidence of serious infections was 7.53 (7.18-7.89) risk per 1,000 patients among systemic nonbiologic-treated patients, 7.38 (5.68-9.57) risk per 1,000 patients among phototherapy-treated patients, and 2.6 (0.45-14.3) risk per 1,000 patients among dupilumab users. After matching, cyclosporine had a significantly reduced 6-month risk (RR 0.87) and prednisone (RR 1.78), azathioprine (RR 1.89), and mycophenolate (RR 3.31) showed increased risks compared with methotrexate. A small number of dupilumab users showed no increased risk (RR 0.33, 95% confidence interval 0.03-3.20). LIMITATIONS: Some comparisons involved small population sizes. CONCLUSION: In this population-based study of adult AD patients, cyclosporine and methotrexate have the lowest 6-month risks of serious infections. Increased risks were observed for prednisone, azathioprine, and mycophenolate relative to methotrexate.

Bridging the Gaps in the Care of Psoriasis and Psoriatic Arthritis: the Role of Combined Clinics.

PURPOSE OF REVIEW: Despite a robust therapeutic landscape, significant gaps exist in the quality of care of psoriatic disease. Thus, an improved understanding of the challenges in providing quality care and the implementation of effective strategies to overcome them is needed. In this review, we summarize the burden of psoriatic disease, discuss the challenges in the care of psoriatic patients, and outline how combined dermatology-rheumatology clinics bridge many of these gaps. RECENT FINDINGS: Multiple challenges are faced in providing high-quality care to patients with psoriasis and psoriatic arthritis from the pre-diagnosis phase of disease to the follow-up period. Challenges are mainly driven by lack of education of patients and healthcare providers, inefficient communication between specialists, lack of a holistic approach to patients, and limitations of available therapies. The Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network (PPACMAN) is working on demonstrating the effectiveness of combined dermatology-rheumatology clinics in addressing some of these challenges. Recent findings show that combined clinic models may improve quality of care by raising awareness of psoriatic disease, fostering educational activities for both patients and physicians, and allowing for comprehensive evaluation and management of patients through improved communications between disciplines. Psoriasis and psoriatic arthritis are complex diseases that often require an interdisciplinary approach. Thus, combined dermatology-rheumatology clinics and local-regional partnerships are potentially effective in improving quality of care in psoriatic disease.
