Pso-Reg: a web registry for psoriasis in real life.

BACKGROUND: Psoriasis (PsO) is a common immune mediated inflammatory disease, affecting about 60 million people worldwide. Although current therapies have dramatically changed the therapeutic approach to the disease, the heterogeneity of responses often results in an essential unmet clinical need. This study describes the design and development of the Psoriasis Registry (Pso-Reg), an Italian electronic-based-registry, aimed to collect real life data of patients with psoriasis. METHODS: Pso-Reg is a multicenter, retrospective and observational cohort study based on the Research Electronic Data Capture (REDcap) tool. Five Italian medical centres were part of the network and all patients affected by PsO were included in the study. Socio-demographic, clinical characteristics, laboratory findings and therapies were collected, and descriptive analysis was carried out. RESULTS: Among the 768 patients analyzed, 446 were men (58.1%), with a mean age of 55.5 years. The first more frequent comorbidity was psoriatic arthritis (26.8%), followed by hypertension (25.3%), diabetes (10%) and dyslipidemia (11.7%). Of the entire cohort, 240 patients (38.2%) had a positive family history for PsO. Vulgar type was the most common phenotype (85.5%), with a major involvement of the scalp (13.8%). The mean PASI (Psoriasis Area Severity Index) score at the baseline was 7.5 (7.8). At the enrolment, 107 patients were treated with topic treatments (13.9%), 5 with phototherapy (0.7%), 92 with cDMARDs (conventional disease-modifying anti-rheumatic drugs) (12.0%) and 471 with biologic therapies (61.3%). CONCLUSIONS: Real-life data from Pso-Reg could contribute providing the rationale for an individual-based strategy and a more tailored approach for the management of psoriasis.

Anti-IL23for nail psoriasis in real life: Results of efficacy and safety during a 52-week period.

Nail psoriasis (NP) is often considered disfiguring for patients with a relevant impact on quality of life (QoL). It is also difficult to treat for dermatologists who are often frustrated by the scarcity of effective therapeutic alternatives in this particular location. Topical therapies are often used as the first-line treatment for mild NP, but efficacy is the modest. Conventional disease-modifying antirheumatic drugs (cDMARDs) (e.g., cyclosporine, methotrexate, acitretin, and dimethyl fumarate) are generally avoided in NP without general cutaneous involvement. Biologics represent, to date, a concrete possibility for the management of these patients. The data from the clinical trials are encouraging, although there are still few data in real-life. Here, we report a study conducted at Siena University Hospital on 20 patients with NP on both hands and feet treated with anti-IL23 for 52 weeks. No differences were evaluated from baseline to week 4 of anti-IL-23 treatment. NAPSI greatly improved at week 24 with almost 60% of patients reaching NAPSI75 and 40% NAPSI50. At week 52, almost 75% of patients reached NAPSI90. No adverse effects were reported in the patients in the study. The clinical response observed in these patients suggests that treatments that target interleukin-23 may be an effective option for NP, especially when refractory to conventional therapies.

Clinical and laboratory characterization of patients with localized scleroderma and response to UVA-1 phototherapy: In vivo and in vitro skin models.

BACKGROUND/PURPOSE: Localized scleroderma (LS) is a rare disease leading to progressive hardening and induration of the skin and subcutaneous tissues. LS is responsive to UVA-1 phototherapy, though its exact mechanism of action dermal fibrosis is yet to be fully elucidated. We aimed to investigate the molecular changes induced by UVA-1 rays in human primary fibroblasts cultures. METHODS: A total of 16 LS patients were treated with medium-dose UVA-1 phototherapy. At baseline, during and after therapy, Localized Scleroderma Assessment Tool, Dermatology Life Quality Index and lesions' staging and mapping were performed along with high-frequency ultrasound (HFUS) examination for dermal thickness assessment. Gene expression analysis for 23 mRNA transcripts, in vitro UVA-1 irradiation and viability tests were realized on lesional fibroblasts' primary cultures, before and 3 months after therapy. RESULTS: The dermal thickness, the LoSCAT and the DLQI progressively decreased starting from the last phototherapy session up to the 6 and 9 month follow-ups (-57% and -60%, respectively). Molecular gene analysis (rt-PCR) revealed that UVA-1 phototherapy exerts multiple effects: the activation of specific anti-fibrotic pathways (e.g., overexpression of CTHRC1 and metalloproteases 1, 2, 7, 8, 9, 12, suppression of TIMP-1), the downregulation of peculiar pro-fibrotic pathways (e.g., downregulation of TGF-ß, TGF-ßrII, Grb2, SMAD 2/3, TNRSF12A, CTGF) through a significant overexpression of IL-1ß; the stabilization of collagen synthesis acting on genes COL1A1, COL3A1, COL8A1, COL10A1, COL12A1. CONCLUSION: UVA-1 phototherapy adds significant benefits in local tissue remodeling, rebalancing the alteration between pro-fibrotic and anti-fibrotic pathways; these changes can be well monitored by HFUS.

UVA-1 phototherapy as adjuvant treatment for eosinophilic fasciitis: in vitro and in vivo functional characterization.

INTRODUCTION: Eosinophilic fasciitis (EF) is a rare autoimmune disease causing progressive induration of dermal, hypodermal, and muscularis fascia. The exact pathogenesis is yet to be fully understood, and a validated therapy protocol still lacks. We here aimed to realize a clinical-functional characterization of these patients. MATERIALS AND METHODS: A total of eight patients (five males, 45 years average) were treated with adjuvant high-dose UVA-1 phototherapy (90 J/cm), after having received the standard systemic immunosuppressive protocol (oral methylprednisolone switched to methotrexate). Body lesion mapping, Localized Scleroderma Assessment Tool (LoSCAT), Dermatology Life Quality Index (DLQI), High-Resolution Ultrasound (HRUS) (13-17MHz), and ultra HRUS (55-70 MHz) were performed at each examination time taking specific anatomical points. Gene expression analysis at a molecular level and in vitro UVA-1 irradiation was realized on lesional fibroblasts primary cultures. RESULTS: The LoSCAT and the DLQI showed to decrease significantly starting from the last UVA-1 session. A significant reduction in muscularis fascia thickness (-50% on average) was estimated starting from 3 months after the last UVA-1 session and maintained up to 12 months follow-up. Tissues was detected by HRUS. The UVA-1 in vitro irradiation of lesional skin sites cells appeared not to affect their viability. Molecular genes analysis revealed a significant reduction of IL-1ß and of TGF-ß genes after phototherapy, while MMPs 1,2,9 gene expression was enhanced. COMMENT: These preliminary in vivo and in vitro findings suggest that UVA-1 phototherapy is a safe and useful adjuvant therapy able to elicit anti-inflammatory effects and stimulate tissue matrix digestion and remodeling at lesional sites.

Management of patients with atopic dermatitis undergoing systemic therapy during COVID-19 pandemic in Italy: Data from the DA-COVID-19 registry.

BACKGROUND: Few and small studies have described the management of immunomodulant/immunosuppressive therapies or phototherapy in atopic dermatitis (AD) patients during coronavirus disease 2019 (COVID-19) pandemic. METHODS: A national registry, named DA-COVID-19 and involving 35 Italian dermatology units, was established in order to evaluate the impact of COVID-19 pandemic on the management of adult AD patients treated with systemic immunomodulant/immunosuppressive medications or phototherapy. Demographic and clinical data were obtained at different timepoints by teledermatology during COVID-19 pandemic, when regular visits were not allowed due to sanitary restrictions. Disease severity was assessed by both physician- and patient-reported assessment scores evaluating itch intensity, sleep disturbances, and AD severity. RESULTS: A total of 1831 patients were included, with 1580/1831 (86.3%) continuing therapy during pandemic. Most patients were treated with dupilumab (86.1%, 1576/1831) that was interrupted in only 9.9% (156/1576) of cases, while systemic immunosuppressive compounds were more frequently withdrawn. Treatment interruption was due to decision of the patient, general practitioner, or dermatologist in 39.9% (114/286), 5.6% (16/286), and 30.1% (86/286) of cases, respectively. Fear of increased susceptibility to SARS-CoV-2 infection (24.8%, 71/286) was one of the main causes of interruption. Sixteen patients (0.9%) resulted positive to SARS-CoV-2 infection; 3 of them (0.2%) were hospitalized but no cases of COVID-related death occurred. CONCLUSIONS: Most AD patients continued systemic treatments during COVID pandemic and lockdown period, without high impact on disease control, particularly dupilumab-treated patients.

Characteristic of chronic plaque psoriasis patients treated with biologics in Italy during the COVID-19 Pandemic: Risk analysis from the PSO-BIO-COVID observational study.

Background: The susceptibility of patients with chronic plaque psoriasis and the risks or benefits related to the use of biological therapies for COVID-19 are unknown. Few data about prevalence, clinical course and outcomes of COVID-19 among psoriatic patients were reported. The aims of this study were 1) to assess the prevalence and severity of COVID-19 in psoriatic patients treated with biologic agents during the first phase of the emergency (22 February to 22 April 2020) in Italy, and 2) to report the clinical outcomes of patients who have been exposed to individuals with confirmed SARS-CoV-2 infection. Methods: Patients with moderate-to-severe chronic plaque psoriasis, aged ≥18 years and undergoing treatment with biologic agents as of 22 February 2020, were eligible to be included in PSO-BIO-COVID study. Demographic and clinical characteristics of patients using any biologic for psoriasis treatment between 22 February and 22 April 2020 were registered. Results: A total of 12,807 psoriatic patients were included in the PSO-BIO-COVID study. In this cohort 26 patients (0.2%) had a swab confirmation of SARS-CoV-2 infection. Eleven patients required hospitalization and two died. Conclusion: The incidence of COVID-19 observed in our cohort of psoriatic patients (0.2%) is similar to that seen in the general population (0.31%) in Italy. However, the course of the disease was mild in most patients. Biological therapies may likely lessen 'cytokine storm' of COVID-19, which sometimes lead to multiple organ failure, ARDS, and death.

Efficacy of Dupilumab in two patients with severe and recalcitrant atopic dermatitis previously treated with extracorporeal photopheresis.

Atopic dermatitis (AD) is a complex disease and can often be a clinical challenge for dermatologists. When standard immunosuppressive therapies fail, extracorporeal phototherapy (ECP) can be considered as a therapeutic option. In recent years, better understanding of the pathogenesis of AD allowed to improve treatment strategies with many emerging therapeutic options. Currently, Dupilumab, a monoclonal antibody that selectively inhibits IL-4 and IL-13, is the only biological drug authorized for the treatment of severe adult atopic dermatitis, refractory to traditional firstline and secondline therapies. ECP, compared to biological therapy, is associated with some disadvantages: it is costly and time-consuming for patients and personnel to administer. Moreover, it should be noted that the completion of the entire procedure takes about 3 hr and must be done in a hospital, while the administration of Dupilumab can be carried out by patients themselves at home. For these reasons and on the basis of our experience, it would be necessary to evaluate whether all patients with refractory atopic dermatitis in treatment with ECP with unsatisfactory clinical response should be switched to recent available target therapies.
