Evaluating the Clinical Meaning of Dermatology Life Quality Index Scores Between Different Phenotypes of Atopic Dermatitis in Patients Before and After Biologic Therapy With Dupilumab.

Background and Objective: Atopic Dermatitis (AD) is the most prevalent inflammatory skin disorder resulting in an intense impact on patients quality of life. The aim of this study is to evaluate the clinical meaning of the DLQI scores documented between different phenotypes of AD patients under biologic therapy with Dupilumab. Method: We conducted a retrospective analysis of 209 patients with AD treated with Dupilumab for 2 years. These patients were categorized into different clinical phenotypes. Severity of the disease was assessed by using the Eczema Area and Severity Index (EASI), Numerical Scale Rating (NRS) for sleep (NRS sleep), pruritus (NRS pruritus) and Dermatology Life Quality Index (DLQI) at baseline and subsequently at 4,12 and 24 months. Results: Our results show that the higher DLQI scores (mean: 18.6, range:9-30) achieved at T0 are associated with a prurigo nodularis AD pattern, while after 24 months (T3) of therapy with Dupilumab, the worst quality of life index results were reported in Flexural and Head-Neck combined clinical phenotypes. Conclusions: Quality of life is probably what matters most as an overall endpoint in AD. Assessing the clinical meaning of DLQI scores across different AD phenotypes could be a further aid when considering decision making factors in patient management.

Towards a better understanding of the use of additives in tattoos.

BACKGROUND: Tattooing is a popular practice worldwide, this practice is not free from complications and the last few decades have seen the raising occurrence of complications and adverse reactions. METHODS: The aim of this study is to evaluate which substances are commonly used as additives among a group of tattoo artists working in Florence, to understand if mixing of colors and dilution of inks can be considered a potential source of infection or hypersensitivity reaction. A questionnaire containing a list of substances suspected to be added during the process of tattooing, was administered in presence of an investigator. RESULTS: Forty-one licensed tattoo artists participated in the study. The cosmetic most frequently used as additive, resulted a rinse on cosmetic (36%) followed by distilled water (34%) and hamamelis lotion (17%). CONCLUSIONS: Our study provides new insights about the procedure of ink dilution and mixing of colors, shedding light on the possible risks related to the use of non-sterile products. The results of our study suggest that mixing of colors and ink dilution can be consider a potential source of infection and hypersensitivity reactions. Additional actions are necessary to strengthen and protect public health.

Effect of dupilumab on sleep disturbances in adult patients with severe atopic dermatitis.

BACKGROUND: Sleep disturbances are common in patients with atopic dermatitis (AD). Considering their relevant burden on health, routine screening of sleep disturbances seems to be very useful in AD adults' management. However, few studies have evaluated the association between sleep disturbances and AD in adults, and real-life data are lacking. The aim of this study was to assess the effect of treatment with dupilumab on sleep disturbances in adult patients with severe atopic dermatitis. METHODS: This is a retrospective, multicenter study including patients (age ≥18 y) with severe atopic dermatitis treated with dupilumab for at least 8 months from January 2019 to January 2020. Patients were evaluated three times: at treatment initiation (T0), at 4 (T4) and 8 months (T8) from the start of treatment. At each visit disease activity was assessed by severity score (Eczema Area and Severity Index [EASI]), patient-reported outcomes (Pruritus Numerical Rating Scale [NRS], Dermatology Life Quality Index [DLQI], and Pittsburgh Sleep Quality Index [PSQI]). Kolmogorov-Smirnov Test was performed to evaluate the normality distribution, Bartlett's Test for homoscedasticity. Since the assumptions were met, ANOVA for repeated measures was performed to evaluate the mean difference of PSQI, EASI, DLQI and pruritus NRS between baseline, the 4th month and the 8th month. In addition, χ2 for Trend Test was performed to evaluate the increasing/decreasing prevalence of poor sleepers. RESULTS: A total of 36 patients (15 females and 21 males) with a mean age of 42.5±14.3 (range 20-67) were included in the study. The mean score for PSQI at TO was 9.0±3.6. At week 16 (T4) the mean score for PSQI was 4.92±2.99 and at week 32 (T8), the mean score for PSQI was 4.3±3.0. EASI, NRS pruritus and DLQI significantly improved during follow-up (P<0.001) whereas PSQI improved significantly at 16 weeks (T4); however, no significant further improvement was observed at 32 weeks. Of the 31 patients (86%) with baseline PSQI≥5, 17 (54%) experienced sleep quality improvement during treatment. Overall, we observed a total of 22 patients (61.1%) having a PSQI<5 at 32 weeks. CONCLUSIONS: Our data show effectiveness of dupilumab in improving sleep disturbances in adult patients with severe AD. However, further studies are required to understand if PSQI could serve as useful evaluating tool.

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.

Patch testing of budesonide in Italy: The SIDAPA baseline series experience, 2018-2019.

BACKGROUND: Budesonide was included in the European Baseline Series in 2000 as the most suitable marker forcorticosteroid hypersensitivity. In the last two decades, a decreasing trend of budesonide allergy has been observed. OBJECTIVES: To estimate the prevalence of positive patch test reactions to budesonide in a large, Italian patch test population, characterizing patients according to MOAHLFA index and evaluating the benefit with extended readings of budesonide patch test. METHODS: Retrospective analysis of patient demographics and patch test results over a 2-year period (2018-2019) was performed at 14 patch test clinics in Italy. RESULTS: Ninety out of 14 544 (0.6%) patients reacted to budesonide 0.01% pet.. Positive reactions were mild in 54.4% and late readings at day 7 showed new positive reactions in 37.8% of patients. The MOAHLFA index showed a significant positive association with male gender, atopic dermatitis, and age >40 years and a significant negative association with hand and face dermatitis. CONCLUSIONS: We documented a low prevalence of budesonide allergy in Italy, confirming its decreasing trend recently reported in the literature. Nevertheless, budesonide needs to be maintained in the baseline series for its good ability to detect corticosteroid sensitization.

Myroxylon pereirae (balsam of Peru): Still worth testing?

BACKGROUND: Because Myroxylon pereirae (MP), or balsam of Peru, is nowadays almost not used "as such," and fragrance mix 1 (FM1) apparently is more sensitive in detecting fragrance allergy, the usefulness of testing MP in baseline series was recently questioned. OBJECTIVES: Identification of the number of clinically relevant patch test reactions to MP not detected by FM1. METHODS: Retrospective analysis of 12 030 patients patch tested with MP and FM1 for contact dermatitis between January 2018 and December 2019 in 13 Italian dermatology clinics. RESULTS: Four hundred thirty-nine patients (3.6%) had a positive patch test reaction to MP; 437 (3.6%) had a positive patch test reaction to FM1. Positive reactions to both MP and FM1 were observed in 119 subjects (1.0%), 310 (2.6%) reacted to MP only, 304 (2.5%) to FM1 only, 5 to MP and sorbitan sesquioleate (SSO), 9 to FM1 and SSO, and 5 to MP, FM1, and SSO. Single sensitizations were clinically relevant in 75.2% of cases for MP (62.9% current, 12.3% past) and 76.3% for FM1 (70.1% current, 6.2% past). CONCLUSIONS: Based on our results, MP appears to be still worth testing along with FM1 in baseline series, because it allows detection of a remarkable number of fragrance allergies, often relevant, which would be otherwise missed.

Dupilumab in Elderly Patients With Severe Atopic Dermatitis.

BACKGROUND: Atopic dermatitis (AD) in the elderly has been poorly investigated, although its incidence is gradually increasing mainly in industrialized countries. Age-specific factors in older patients must be considered when selecting treatment options. OBJECTIVES: To evaluate the efficacy and tolerability of dupilumab in treating elderly patients with severe AD. METHODS: This was a retrospective, multicenter study involving 26 elderly patients (age, ≥65 years) with severe AD who were treated with dupilumab for at least 16 weeks. Absolute and percentage frequencies were used to evaluate qualitative variables and mean and SD for quantitative ones. For Eczema Area and Severity Index (EASI), Pruritus Numeric Rating Scale (NRS), and Dermatology Life Quality Index (DLQI), the median was also calculated. Wilcoxon test was used to evaluate the variations in EASI, Pruritus NRS, and DLQI observed between the 2 examinations. RESULTS: After 4 months of therapy, the majority of patients showed a significant improvement in EASI (64.4%), Pruritus NRS (58.2%), and DLQI (44.9%). Only 11% of patients reported mild or moderate conjunctivitis. CONCLUSIONS: To the best of our knowledge, this is the first study concerning the use of dupilumab in the elderly with severe AD. Our data show the effectiveness of dupilumab in this particular population with a lower percentage of conjunctivitis than observed in studies on adults and also excellent control of itching. Only larger, controlled case studies will be able to clarify whether the dosage or frequency of administration of dupilumab in these patients should be different from the protocol used for adults.

Tuscan Consensus on the diagnosis, treatment and follow up of adult atopic dermatitis.

Atopic dermatitis (AD) is an inflammatory disease with a chronic-relapsing course that is intensely itchy. A correct diagnosis of AD in adults and consequently appropriate clinical therapeutic management is a critical issue for extreme clinical expression heterogeneity and various grades of disease severity. In order to ensure high levels of care and standardization of clinical therapeutic management of Adult AD, the decision was taken to create an AD Tuscan Consensus Group (the Group), to work on and validate a consensus based regional clinical-therapeutic management model. The aims of the Group were to find agreement on the criteria for diagnosis, scoring of severity, multidisciplinary approach and treatment of adult atopic dermatitis and to create an easier way for patients to access specialized dermatology outpatient services and importantly to reduce waiting lists and costs related to the management of AD. The Tuscan Consensus Group adopted a simplified Delphi method, in three principal steps: 1) literature metanalysis and critical review of patient's clinical experience to identify the main areas considered questionable or uncertain; 2) discussion of those areas requiring consensus and statement definition through four different sub-committees (diagnosis, severity evaluation, scoring and comorbidities); 3) a consensus based simplified process with final approval of each statement by plenary vote with approval >80% of the participants. The Group here presents and discusses the consensus based recommendation statements on adult atopic dermatitis.
