RESUMO

INTRODUCTION: Generalized pustular psoriasis (GPP) is a rare and chronic, debilitating skin condition characterized, in its acute flare phase, by clinically severe and potentially life-threatening systemic manifestations. Data on GPP are still scanty, particularly in Europe and at a national level. The aim of this study was to provide expert indications on several disease-related and patient-related aspects of GPP, with specific focus to the Italian context. METHODS: We conducted an iterative eDelphi study following the recommended criteria for reporting methods and results. After a thorough bibliographic review aimed to identify unknown or controversial issues in GPP, the following areas were investigated through a few specific questions/statements for each area: (1) disease epidemiology; (2) disease characteristics, with specific interest toward GPP flares; (3) diagnosis and diagnostic delay; (4) GPP treatment; (5) GPP patient journey and use of healthcare resources in Italy; (6) unmet needs and quality of life. An Executive Board of 9 principal investigators revised and approved the topics to be examined and overviewed the whole project. A total of 35 experts from different Italian areas, including 34 board-certified Italian dermatologists and 1 representative of patients' associations, took part in the study. RESULTS: A high agreement in responses from Italian experts emerged during two eDelphi iterations on - among several other aspects - GPP prevalence and incidence in Italy, use of European Rare and Severe Psoriasis Expert Network diagnostic criteria, flare frequency and duration, best diagnostic and care pathway, and main unmet needs of Italian patients. On the other hand, a broad spectrum of treatments (of different drug classes) was reported both in the acute and chronic phases of GPP, and no consensus on the issue was thus achieved. CONCLUSIONS: Consensus findings from this Delphi study of GPP experts may be useful to fill gaps of knowledge and improve awareness of this rare disease, as well as to help clinical and public health management of GPP in Italy.

RESUMO

BACKGROUND: There is limited epidemiological evidence on outcomes associated with dupilumab exposure during pregnancy; monitoring pregnancy outcomes in large populations is required. OBJECTIVE: To investigate the potential association between exposure to dupilumab in pregnant women with atopic dermatitis and any adverse pregnancy, neonatal, congenital and post-partum outcomes. METHODS: We performed a multicentre retrospective cohort study across 19 Italian tertiary referral hospital. Childbearing women were eligible if aged 18-49 years and carried out the pregnancy between 1 October 2018 and 1 September 2022. RESULTS: We retrospectively screened records of 5062 patients receiving dupilumab regardless of age and gender, identifying 951 female atopic dermatitis patients of childbearing age, 29 of whom had been exposed to the drug during pregnancy (3%). The median duration of dupilumab treatment prior to conception was 22.5 weeks (range: 3-118). The median time of exposure to the drug during pregnancy was 6 weeks (range: 2-24). All the documented pregnancies were unplanned, and the drug was discontinued in all cases once pregnancy status was reported. The comparison of the study cohort and the control group found no significant drug-associated risk for adverse pregnancy, congenital, neonatal or post-partum outcomes. The absence of a statistically significant effect of exposure on the event was confirmed by bivariate analysis and multivariate analysis adjusted for other confounding factors. CONCLUSIONS: This cohort of pregnant patients exposed to dupilumab adds to the existing evidence concerning the safety of biologic agents in pregnancy. No safety issues were identified regarding the primary outcome assessed. In clinical practice, these data provide reassurance in case of dupilumab exposure during the first trimester. However, the continuous use of dupilumab throughout pregnancy warrants further research.

RESUMO

BACKGROUND: Previously, a new dichotomous outcome was developed, calculated as 55% reduction in the International Hidradenitis Suppurativa 4 (IHS4-55) score. It was validated in datasets of adalimumab and placebo-treated HS patients. External validation is an important aspect of clinical outcomes. OBJECTIVES: We aimed to externally validate the novel dichotomous IHS4-55 in a non-biologic treated dataset of HS patients. METHODS: Data from a previously published European-wide prospective clinical study of antibiotic treatment of HS patients were used to assess the association of IHS4-55 achievement with individual reduction in inflammatory nodules, abscesses, and draining tunnels. Moreover, the associations between IHS4-55 positivity and achievement of the minimal clinically important differences (MCIDs) for Dermatology Life Quality Index (DLQI), Numerical Rating Scale (NRS) Pain, and NRS Pruritus were analyzed. RESULTS: Data were obtained from 283 individual patients, of which 36.4% (103/283) were treated with clindamycin and rifampicin and 63.6% (180/283) with tetracyclines for 12 weeks. Achievers of the IHS4-55 demonstrated a significant reduction the counts of inflammatory nodules, abscesses, and draining tunnels (all p < 0.001). Additionally, IHS4-55 achievers had an odds ratio for achieving the MCID of DLQI, NRS Pain, and NRS Pruritus of 2.16 (95% CI 1.28-3.65, p < 0.01), 1.79 (95% CI 1.10-2.91, p < 0.05), and 1.95 (95% CI 1.18-3.22, p < 0.01), respectively. CONCLUSIONS: This study shows the external validity of the novel IHS4-55 by demonstrating a significant association between IHS4-55 achievement and a reduction in inflammatory lesion counts as well as achievement of MCIDs for DLQI, NRS Pain, and NRS Pruritus in an antibiotic-treated cohort. These findings support the use of the IHS4-55 as a novel primary outcome measure in clinical trials.

RESUMO

Psoriasis is a multifactorial, chronic, auto- inflammatory disease, with a worldwide prevalence of around 2%, subtended by robust genetic predisposition and autoimmune pathogenic traits. The disease, mainly involving the skin and joints, is featured by erythemato-squamous lesions, with a chronic relapsing course and relevant systemic comorbidities. Apremilast is a novel oral agent that has recently been made available to dermatologists for the treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis. Although it is considered as relatively safe molecule with few contraindications, experience with Apremilast in the real-world setting for cancer patients with moderate-to-severe plaque psoriasis is lacking. Hence, we report the real-life experience in patients with psoriasis and a history of cancer who underwent treatment with Apremilast for 104 weeks.

RESUMO

New biologic agents targeting interleukin (IL)23/T-helper17 axis, such as tildrakizumab, have been developed for the treatment of plaque psoriasis. To analyze the efficacy and safety of tildrakizumab in a real life setting of patients affected by moderate-to-severe psoriasis over a 28-week treatment period. A multicentric retrospective study was conducted in patients who initiated tildrakizumab between February 2020 and March 2021. Psoriasis Area and Severity Index-PASI was measured at baseline and after 4, 16 and 28 weeks. The percentage change in PASI value from baseline to the considered time-points, proportion of patients with absolute PASI <3 at week 28 and the percentages of achieving a PASI75 or PASI90 response were assessed. Data about potential safety issues and adverse events (AEs) were collected. Statistical analysis were performed for establish clinical efficacy and for variables predicting clinical response. Fifty nine patients with psoriasis were included. Overall mean PASI percentage reduction was of 88% from baseline to week 28 and 47 out of 59 patients (79.7%) at week 28 had an absolute PASI <3. PASI75 and PASI90 responses at week 28 were achieved by 48 (81.40%) patients and 38 (64.4.0%) patients, respectively. No substantial associations between gender, body mass index - BMI, PASI at baseline and prior exposition to biological therapies and the efficacy endpoints were retrieved. No serious safety issues or discontinuations related to adverse events were reported. In our real-life study, tildrakizumab showed high efficacy and a favorable safety profile, regardless of patient- and disease-related factors.

RESUMO

To avoid exposure to SARS-COV-2, healthcare professionals must use personal protective equipment (PPE). Their use has been related to a series of adverse effects; the most frequent adverse events were headache, dyspnoea, and pressure injuries. Skin adverse effects are very common, including contact dermatitis, itching, erythema, and acneiform eruptions. The objective of this study is to evaluate the skin problems caused by personal protection equipment (PPE) in health care workers (HCWs) and to individuate eventual risk factors. From May to June 2020 a retrospective observational multi-centric study conducted by an online survey sent by email, involving 10 hospital centers, was performed. We considered as independent variables gender and age, occupational group and sector, time of utilization, type and material of PPE. We tested 3 types of PPE: gloves, bonnet, and mask for different time of utilization (<1, 1-3, 3-6, >6 h). We performed a multiple logistic regression model to correlate them with skin adverse events occurrence. Among all the 1184 participants, 292 workers reported a dermatological pathology: 45 (15.41%) had psoriasis, 54 (18.49%) eczema, 38 (13.01%) acne, 48 (16.44%) seborrheic dermatitis, and 107 (36.64%) other. In our sample previous inflammatory dermatological conditions, female sex, prolonged use of PPE were significant risk factors for developing skin related adverse events considering all the PPE considered. The use of PPE is still mandatory in the hospital setting and skin adverse reactions still represent a global problem. Although data from Europe are limited, our study highlighted the importance of the problem of PPE skin reactions in a large sample of Italian healthcare professionals.

RESUMO

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.

RESUMO

BACKGROUND: COVID-19 is associated with a wide range of skin manifestations. OBJECTIVE: To describe the clinical characteristics of COVID-19-associated skin manifestations and explore the relationships among the 6 main cutaneous phenotypes and systemic findings. METHODS: Twenty-one Italian Dermatology Units were asked to collect the demographic, clinical, and histopathologic data of 200 patients with COVID-19-associated skin manifestations. The severity of COVID-19 was classified as asymptomatic, mild, moderate, or severe. RESULTS: A chilblain-like acral pattern was significantly associated with a younger age (P < .0001) and, after adjusting for age, significantly associated with less severe COVID-19 (P = .0009). However, the median duration of chilblain-like lesions was significantly longer than that of the other cutaneous manifestations taken together (P < .0001). Patients with moderate/severe COVID-19 were more represented than those with asymptomatic/mild COVID-19 among the patients with cutaneous manifestations other than chilblain-like lesions, but only the confluent erythematous/maculo-papular/morbilliform phenotype was significantly associated with more severe COVID-19 (P = .015), and this significance disappeared after adjustment for age. LIMITATIONS: Laboratory confirmation of COVID-19 was not possible in all cases. CONCLUSIONS: After adjustment for age, there was no clear-cut spectrum of COVID-19 severity in patients with COVID-19-related skin manifestations, although chilblain-like acral lesions were more frequent in younger patients with asymptomatic/pauci-symptomatic COVID-19.

RESUMO

BACKGROUND: Tetracyclines and clindamycin plus rifampicin combination therapy are both considered first-line therapy in current hidradenitis suppurativa guidelines. However, evidence for their efficacy is drawn from small studies, often without validated outcomes. OBJECTIVE: To assess the 12-week efficacy of oral tetracyclines and a combination of clindamycin and rifampicin. METHODS: A prospective, international cohort study performed between October 2018 and August 2019. RESULTS: In total, 63.6% of the included 283 patients received oral tetracyclines, and 36.4% were treated with clindamycin and rifampicin. Both groups showed a significant decrease in International Hidradenitis Suppurativa Severity Score System from baseline (both P < .001). The Hidradenitis Suppurativa Clinical Response (HiSCR) was achieved in 40.1% and 48.2% of patients, respectively (P = .26). Patient characteristics or disease severity were not associated with the attainment of HiSCR or the minimal clinically important differences for the Dermatology Life Quality Index and pain. LIMITATIONS: Cohort study. Respectively, 23.9% and 19.4% of patients had to be excluded from the HiSCR analysis for the tetracycline and combination therapy group because of a low abscess and nodule count at baseline. CONCLUSION: This study shows significant efficacy of both tetracycline treatment and clindamycin and rifampicin combination therapy after 12 weeks in patients with hidradenitis suppurativa. No significant differences in efficacy were observed between the 2 treatments, regardless of disease severity.

RESUMO

Topical treatment is the mainstay for mild or moderate psoriasis, but patients are generally little satisfied. Calcipotriol/betamethasone dipropionate (Cal/BD) cutaneous foam has shown to improve signs and symptoms in plaque psoriasis patients. This study assessed patient's satisfaction with Cal/BD foam in a real-life Italian dermatological clinical practice. A multicenter, 4-week observational prospective cohort study enrolled, in 17 Italian dermatology clinics, adult patients with plaque psoriasis on the body and/or scalp. Treatment satisfaction was assessed by 9-item Treatment Satisfaction Questionnaire for Medication (TSQM-9), preference over previous treatments by Patient Preference Questionnaire (PPQ), and change in disease state by Psoriasis Area Severity Index (PASI). Overall 256 patients were eligible, with a mean (SD) age of 55.6 (15.4) years, 59.4% were males. Psoriasis severity was mild in 52.0% of patients, moderate in 43.3%, and severe in 4.7%. Scalp involvement was present in 36.7% of patients. Previous antipsoriatic treatments had been received by 80.5% of patients. TSQM-9 median (25th-75th percentile) scores were 83.3 (66.7-88.9) for effectiveness, 77.8 (66.7-88.9) for convenience, and 78.6 (64.3-92.9) for global satisfaction. Mean (SD) PASI value decreased from 7.3 (4.8) to 2.1 (2.7) after 4 weeks. More than 90% of patients previously treated for psoriasis evaluated the Cal/BD foam more effective, easier to use and better tolerated compared to previous topical treatments at PPQ. This observational study provides real-life evidence of a high level of satisfaction with effectiveness and convenience of the Cal/BD foam in a cohort of plaque psoriasis patients, with an objective improvement in PASI.

RESUMO

This study evaluated whether secukinumab treatment for patients with moderate to severe plaque psoriasis correlates with improvements in symptoms of anxiety and depression. SUPREME was a 24-week, phase IIIb, multicentre, prospective study conducted across 50 centres in Italy with an extension period of up to 72 weeks. Assessments used were: Psoriasis Area Sever-ity Index (PASI), Hospital Anxiety and Depression Scale (HADS) - Anxiety (HADS-A), and HADS - Depression (HADS-D) scores and Dermatology Quality Life Index (DLQI). Compared with baseline, a significantly greater proportion of patients who reported moderate to severe clinical symptoms of anxiety or depression (HADS-A or HADS-D ≥ 11) were free of moderate to severe symptoms at weeks 16 and 48. The PASI and DLQI scores reduced over time with secukinumab treatment. Psoriasis treatment with secukinumab for 48 weeks resulted in significantly improved skin clearance and a parallel improvement in symptoms of anxiety and depression, assessed by HADS.

RESUMO

Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in terms of Psoriasis Area and Severity Index (PASI) 90 in patients with moderate-to-severe plaque psoriasis. Based on PASI 90 response at week 16, patients were stratified as PASI 90 responders (PASI90R, n = 337) or non-responders (PASI90NR, n = 72). At week 20, 94.2% (n = 295/313) achieved PASI 90/100 response in PASI90R, with response maintained through week 48 (89.6%, n = 189/211). An increased proportion of patients achieved PASI 90/100 response in PASI90NR (week 20: 29.9%, n = 20/67; week 48: 57.1%, n = 20/35). Overall, 64.4% patients achieved absolute PASI score = 0 at week 24 with response sustained to week 48 (66.9%). Secukinumab showed sustained and stable efficacy in maintaining PASI 90 response in patients with moderate-to-severe plaque psoriasis up to week 48.

RESUMO

OBJECTIVE: To assess the role of CD3+ CD20+ CD4- CD8- double-negative (DN) or CD3+CD20+ CD4/CD8+ T cells and the related pro-inflammatory cytokines in the humor aqueous, in mediating retinal microvascular changes in patients with chronic plaque-type moderate to severe psoriasis. DESIGN: A total of 76 patients (57.6 ± 11.7 years) with chronic plaque-type psoriasis were initially evaluated. Nineteen patients (19 eyes) and 19 healthy volunteers (19 eyes) were subjected to dermatological evaluation with Psoriasis Area Severity Index (PASI) and the Dermatology life quality index (DLQI). Retinal images were processed using an automatized software. On the same day, a venous sample was collected and analyzed using multiparametric flow cytometry. Three out of 6 patients who presented cataract, consented to perform surgery with humor aqueous collection. The samples were analyzed using a Multi-Analyte ELISA kit for the simultaneous quantification of IL1α, IL1ß, IL2, IL4, IL6, IL8, IL10, IL12, IL17A, IFNγ, TNF-α, GMCSF. RESULTS: The CD3+CD4+/CD8+CD20+CD56- T cells expression was greater in the psoriatic patients (+73.9%, P < 0.001) compared to controls, but not the DN T cells (-8.2%, P = 0.30). Ocular complications were diagnosed in 61.1% of patients, microvascular parameters including artero-venous ratio (P = 0.04), subfoveal choriocapillaris/Sattler's layer, and choroidal thickness (CT, both P < 0.001) were significantly altered in psoriasis subgroup. The increased circulating levels of the CD3+CD4+/CD8+CD20+CD56- T cells were associated with thinning of subfoveal CT (P = 0.03) and Haller's layer (P = 0.01). Instead, the DN T cells presented an inverse relationship with disease duration (P = 0.02), DLQI score (P = 0.02), and the use of biological therapy (P = 0.05). The related cytokine patterns possibly modified in this cellular context have been investigated. No significant differences were observed in cytokines levels between psoriasis and controls, the most significant difference was detected on IL-6, without reaching statistical significance (fold change of 1.4, P = 0.13). CONCLUSION: Our findings demonstrated that CD20+ T cell subpopulation is highly represented in psoriasis regardless of the use of immunomodulatory therapies, and the diffuse microvascular alterations suggested possible endothelial damage as mainstream for the genesis of psoriatic-mediated complications as further supported by the comparable concentrations of cytokines, at least as humor aqueous content, with respect to healthy eyes.

RESUMO

Acne is a chronic inflammatory relapsing disease that affect predominantly adolescents, with scarring as a frequent sequele. Early and appropriate therapy allows better management of the disease, longer remission, scars risk reduction, and improvement of quality of life. According to therapeutic algorithm, systemic isotretinoin can be used in severe acne and also in moderate forms resistant to other systemic treatments. The aims of this real-life observational study were to determine and compare the effectiveness of isotretinoin evaluated by Global Acne Grading System and Acne Quality of Life in moderate and in severe acne, correlation between efficacy and cumulative dose of isotretinoin, tolerability, and recurrence rate. Moreover, the differences in efficacy and tolerability between male and female patients were compared. The treatment with systemic isotretinoin led to an improvement in acne severity and quality of life in all observed subjects.

RESUMO

Psoriasis is a chronic inflammatory systemic disease caused by deregulation of the interleukin-23/-17 axis that allows the activation of Th17 lymphocytes and the reprogramming of keratinocytes proliferative response, thereby inducing the secretion of cyto-/chemokines and antimicrobial peptides. Beside cell-to-cell contacts and release of cytokines, hormones and second messengers, cells communicate each other through the release of extracellular vesicles containing DNA, RNA, microRNAs and proteins. It has been reported the alteration of extracellular vesicles trafficking in several diseases, but there is scarce evidence of the involvement of extracellular vesicles trafficking in the pathogenesis of psoriasis. The main goal of the study was to characterize the release, the cargo content and the capacity to transfer bioactive molecules of extracellular vesicles produced by keratinocytes following recombinant IL-17A treatment if compared to untreated keratinocytes. A combined approach of standard ultracentrifugation, RNA isolation and real-time RT-PCR techniques was used to characterize extracellular vesicles cargo. Flow cytometry was used to quantitatively and qualitatively analyse extracellular vesicles and to evaluate cell-to-cell extracellular vesicles transfer. We report that the treatment of human keratinocytes with IL-17A significantly modifies the extracellular vesicles cargo and release. Vesicles from IL-17A-treated cells display a specific pattern of mRNA which is undid by IL-17A neutralization. Extracellular vesicles are taken up by acceptor cells irrespective of their content but only those derived from IL-17A-treated cells enable recipient cells to express psoriasis-associated mRNA. The results imply a role of extracellular vesicles in amplifying the pro-inflammatory cascade induced in keratinocyte by pro-psoriatic cytokines.

RESUMO

Celiac disease (CD) is an autoimmune enteropathy that primarily affects the small intestine and is characterized by atrophy of intestinal villi. The manifestations of the disease improve following a gluten-free diet (GFD). CD is associated with various extra-intestinal diseases. Several skin manifestations are described in CD patients. The present paper reviews all CD-associated skin diseases reported in the literature and tries to analyze the pathogenic mechanisms possibly involved in these associations. Different hypotheses have been proposed to explain the possible mechanisms involved in every association between CD and cutaneous manifestations. An abnormal small intestinal permeability seems to be implicated in various dermatological manifestations. However, most of the associations between CD and cutaneous diseases is based on case reports and case series and a few controlled studies. To better assess the real involvement of the cutaneous district in CD patients, large multicentric controlled clinical trials are required.

RESUMO

Chronic spontaneous urticaria (CSU) is perceived as a difficult to manage disease with negative impact on quality of life. The aim of this study was to highlight how to improve the care of people with CSU, using the methodology of narrative medicine. From June 2014 to March 2015, CSU-diagnosed patients and their physicians were asked to record their experiences of the condition in writing. Fourteen healthcare teams participated: 41% considered CSU as a challenge to overcome, while 22% experienced CSU as a big commitment. The number of professional involved was evaluated as insufficient in 11 hospitals. Seventy-five percent of the 190 Italian patients had visited 3 or more physicians before receiving a final diagnosis, with a perceived waste of time and resources. The therapeutic pathways were described as unsatisfactory in 83% of cases. As a result, anger and frustration were life-dominant emotions in 92% of patients. The critical points of the care pathway are related to organizational issues and lack of awareness.
