Short-, mid- and long-term efficacy of dupilumab in moderate to severe atopic dermatitis: a real life multicenter Italian study on 2576 patients.

BACKGROUND: The efficacy and safety of dupilumab in atopic dermatitis (AD) have been defined in clinical trials but limited real-world evidence on long term treatment outcomes are currently available to inform clinical decisions. OBJECTIVES: to describe long-term effectiveness and safety of dupilumab up to 48 months in patients with moderate-to-severe AD. METHODS: a multicenter, retrospective, dynamic cohort study was conducted to assess long term effectiveness and safety of dupilumab in patients with moderate to severe AD in a real-world setting. Predictors of minimal disease activity (MDA) optimal treatment target criteria (defined as the simultaneous achievement of EASI90, itch NRS score ≤1, sleep NRS score ≤1 and DLQI ≤1) were investigated. RESULTS: 2576 patients were enrolled from June 2018 to July 2022. MDA optimal treatment target criteria were achieved by 506 (21.91%), 769 (40.63%), 628 (50.36%), 330 (55.37%) and 58 (54.72%) of those that reached 4, 12, 24, 36 and 48 months of follow-up, respectively. Logistic regression revealed a negative effect on MDA achievement for conjunctivitis and food allergy at all timepoints. Adverse events (AE) were mild and were observed in 373 (15.78%), 166 (7.02%), 83 (6.43%), 27 (4.50%) and 5 (4.55%) of those that reached 4, 12, 24, 36 and 48 months of follow-up. Conjunctivitis was the most frequently reported AE during the available follow-up. AE led to treatment discontinuation in <1% of patients during the evaluated time periods. CONCLUSION: High long-term effectiveness and safety of dupilumab were confirmed in this dynamic cohort of patients with moderate to severe AD, regardless of clinical phenotype and course at baseline. Further research will be needed to investigate the effect of Th2 comorbidities and disease duration on the response to dupilumab and other newer therapeutics for AD.

DECISA Project (DErmatology Clinics in Italy: Survey on Alitretinoin): A real-life retrospective cohort multicenter study on 438 subjects with chronic hand eczema.

Alitretinoin is the only systemic agent approved to treat moderate-severe chronic hand eczema (CHE) unresponsive to potent topical corticosteroids. No nationwide Italian data regarding real-life efficacy, safety, and tolerability of treatment are available. The DECISA project (DErmatology Clinics in Italy: Survey on Alitretinoin) retrospectively examined data from a registry including 15 Dermatology Clinics authorized to prescription of alitretinoin for CHE patients. Disease severity was assessed at baseline, and after 3 and 6 months of treatment, using the 5-point Physician Global Assessment (PGA) and the modified Total Lesion-Symptoms-Severity (mTLSS) scores. Between November 2010 and July 2018, data of 248 male and 190 female patients (mean age 49.71 ± 13.20 years) treated with alitretinoin were collected. Of them, 43.2% had irritant contact dermatitis, 22.2% allergic contact dermatitis, 18.0% atopic dermatitis, 16.7% mixed (irritant/allergic) type of eczema. At 3 months, the 420 re-evaluated patients showed significantly reduced mTLSS and PGA (P < .0000001 vs baseline for both); PGA was clear/almost clear in 35.6% of cases. At 6 months, the 341 re-evaluated patients showed significant (P < .0000001) improvement of mTLSS and PGA vs baseline and 3 months (PGA clear/almost clear: 41.4%). Relapses occurred in 125 patients; 58 underwent an additional course of alitretinoin, with similarly good results. No relevant safety issues were reported; 86 patients experienced adverse effects, which forced 40 to prematurely stop treatment. The DECISA project results confirm the real-life efficacy, safety and tolerability of alitretinoin in the treatment of moderate to severe CHE refractory to standard topical therapies.

Living with Chronic Spontaneous Urticaria in Italy: A Narrative Medicine Project to Improve the Pathway of Patient Care.

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.

Allergic contact dermatitis to triethanolamine in a child.

Triethanolamine is used as an emulsifier in many cosmetics and in topical medications, yet the occurrence of contact dermatitis to cosmetics containing triethanolamine is rare in childhood. Our case highlights how young age should not be a deterrent to investigation and demonstrates the importance of patch testing with selected allergens.

Efficacy of treatment with oral alitretinoin in patient suffering from lichen simplex chronicus and severe atopic dermatitis of hands.

Lichen simplex chronicus (LSC) is a skin disorder characterized by chronic itching and scratching, which can lead to thick, leathery, brownish skin, sometimes with papules and can be associated with atopic eczema. We report the case of a 52-year-old man with a 45-year atopic condition and presenting LSC in his dorsum. After a 3-month treatment with alitretinoin at the daily dosage of 30 mg, we have observed a moderate improvement of the hand eczema together with a substantial clinical improvement of LSC and an almost complete resolution of pruritus. We want to report this peculiar case to suggest the use of oral alitretinoin for LSC.

Clinical and epidemiological features of textile contact dermatitis: an Italian multicentre study.

BACKGROUND: The prevalence of occupational and non-occupational textile dermatitis seems to be increasing, probably because of changed textile manufacturing techniques. OBJECTIVE: Evaluation of the clinical features and epidemiology of textile contact dermatitis (TCD) in Italy. METHODS: Demographic data, clinical history aspects, atopy and positive patch test reactions to occupational and non-occupational allergens were investigated in 277 textile dermatitis patients. RESULTS: Contact dermatitis was the most frequent clinical presentation (95.3%). TCD was more common in females, in the fourth to fifth decades of life, and in atopic dermatitis patients. The lesions were prevalently eczematous (74.2%), and mostly located on the trunk and lower limbs in non-occupational cases, and on the hands in textile workers. Allergic TCD (58.3%) was more frequent than irritant TCD. The dyes (Disperse Blue 124, Disperse Blue 106, and Disperse Yellow 3) were most frequently responsible (79.8%), especially in non-occupational TCD. Formaldehyde and resins were more important in occupational TCD. Concomitant reactions among textile dyes and/or finishing resins were observed in 50.0% of patients. CONCLUSIONS: Some strategies (sensitization potential of new textile chemicals, more stable dyes, reduced levels of formaldehyde in clothing, and collaboration with textile industry and trade associations) should be adopted to decrease the TCD incidence and update the textile patch testing series.

Cost and quality of life in patients with severe chronic hand eczema refractory to standard therapy with topical potent corticosteroids.

BACKGROUND: Little is known about the socio-economic burden of severe chronic hand eczema in patients refractory to treatment with potent corticosteroids. OBJECTIVES: To estimate the socio-economic burden of severe chronic hand eczema refractory to potent topical corticosteroids, and to establish an algorithm for the estimation of the health-related quality of life EuroQol five-dimensional (EQ-5D) utility index from the Dermatology Life Quality Index (DLQI) summary score. METHODS: A multicentre cost of illness study was conducted, adopting the societal perspective. Adult patients with severe and refractory chronic hand eczema were enrolled. Direct (e.g. drug treatment and travel) and indirect (i.e. loss of productivity) mean costs/patient-month were estimated. Health-related quality of life was assessed with the EQ-5D and DLQI questionnaires. An ordinary least square regression model was used to investigate relationships between health-related quality of life scores. RESULTS: One hundred and four valid patients (mean age 44.5 years, 39.4% male) participated. Overall mean costs were €418.3/patient-month: loss of productivity contributed 43.7%, followed by hospitalization (16.1%) and travel (10.3%). Health-related quality of life scores were, on average, 0.50 (EQ-5D utility) and 11.3 (DLQI). Utility and DLQI summary were significantly related to each other. CONCLUSIONS: Wellbeing and loss of productivity are the most important consequences in these patients. Appropriate treatment is necessary to improve patient health and productivity, which will contribute to reducing societal costs.

Exploring the Co-occurrence of dermatophyte infection and ichthyosis: A report of 3 cases.

Dermatophyte infections frequently pose diagnostic challenges, especially when occurring alongside ichthyosis, a genetic skin disorder characterized by dry, thickened, scaly skin. This case series outlines three cases where dermatophyte infections overlapped with ichthyosis, emphasizing the complexities in clinical identification and differential diagnosis. Atypical clinical presentations in these cases led to initial misdiagnoses. Ichthyosis, a genetic skin disorder characterized by thickened and scaly skin, creates an environment conducive to dermatophyte settlement, complicating the diagnostic process. The cases highlight the importance of considering fungal infections, even when clinical features deviate from the expected course. A vigilant diagnostic approach, including mycological examinations, is crucial for accurate identification and timely management.

Management of Patients Affected by Moderate-to-Severe Atopic Dermatitis with JAK Inhibitors in Real-World Clinical Practice: An Italian Delphi Consensus.

INTRODUCTION: Several systemic therapies have been approved for the treatment of severe AD. In particular, Janus kinase inhibitors (JAKi), including abrocitinib, baricitinib, and upadacitinib, recently received approval for the treatment of patients with severe AD after being evaluated in several clinical trials. However, a few concerns have been raised regarding their long-term safety and the management of these drugs in real-world clinical practice. In this article we described the results of a Delphi consensus aimed at describing the knowledge on JAKi and focusing, in particular, on providing clinical recommendations for dermatologists in daily practice regarding the use of these drugs. METHODS: Twelve Italian dermatologists reviewed the most recent literature regarding the efficacy and safety profiles of JAKi and proposed 24 statements. RESULTS: Agreement was reached for statements focusing on three main topics: (1) place in therapy of JAKi in patients with moderate-to-severe AD; (2) effectiveness and safety of JAK inhibitors in different phenotypes; (3) different approaches to the management of patients treated with JAKi in clinical practice. The panel proposed several recommendations regarding all the statements. CONCLUSION: Given the wide use of JAKi in clinical practice, it is crucial to establish a specific follow-up for each patient's phenotype in order to achieve the best possible clinical outcome and minimize potential adverse events.

Dupilumab-Associated Blepharoconjunctivitis: Clinical and Morphological Aspects.

PURPOSE: To describe the clinical and morphologic changes in the ocular surface microstructure of patients affected with moderate-to-severe Atopic Dermatitis (AD) before and during Dupilumab treatment. METHODS: This is a monocentric observational study on thirty-three patients affected with AD before and during Dupilumab treatment. All patients underwent a slit-lamp examination: complete clinical assessment, Break Up Time test (BUT), Schirmer test, and corneal staining grading (Oxford scale) were performed. Meibomian Glands Dysfunction (MGD) evaluation (Meibography), Non-invasive Keratograph Break Up Time test (NIKBUT), Tear Meniscus Height (TMH), and ocular Redness Score (RS) have been investigated using an OCULUS Keratograph. In vivo images of the conjunctiva, cornea, and meibomian glands have been acquired by confocal microscopy. RESULTS: Sixty-six eyes were included in our study: twenty-two eyes of 11 naive patients with indication for treatment but not in therapy yet (Group 1) and forty-four eyes of 22 patients treated with Dupilumab for at least 4 months (subcutaneous administration of 300 mg every 2 weeks) (Group 2). Either patients treated with Dupilumab or naive patients with moderate-to-severe forms of AD had a tear film instability (TBUT and NIKBUT reduced), whereas the quantity of the tear film was overall normal (Schirmer test and TMH), without statistically significant differences between the two groups. When Meibography was performed with the Keratograph, the difference between Group 1 and Group 2 was statistically significant in terms of Meiboscore (p = 0.0043 and p = 0.0242, respectively), as well as the difference in terms of mean RS. These results paired well with the confocal microscopy results in which we found a decrease in the goblet cell population in the conjunctival epithelium in the treated group (5.2 cells/mm), along with inflammatory cells that were more concentrated around the adenoid lumina of the meibomian glands. CONCLUSIONS: In recent years, the use of Dupilumab has been increasing, but mild-to-severe conjunctivitis is a common side effect. Our major results demonstrate a loss of meibomian glands at the Keratograph examination: we can assume a reduced meibum secretion and an evaporative dry eye with MGD. We suggest that the inflammation of the ocular surface may involve not only the cornea and the conjunctiva, but also the meibomian glands, and Dupilumab may play a role. However, the frequency of clear conjunctivitis is not as common as reported in the literature.

Is Pediatric Melanoma Really That Different from Adult Melanoma? A Multicenter Epidemiological, Clinical and Dermoscopic Study.

PURPOSE: To improve the diagnostic accuracy and optimal management of pediatric melanomas. METHODS: We conducted a retrospective descriptive, multicenter study of the epidemiological, clinical, and dermoscopic characteristics of histopathologically proven melanomas diagnosed in patients less than 18 years old. Data on sociodemographic variables, clinical and dermoscopic characteristics, histopathology, local extension, therapy and follow-up, lymph node staging, and outcome were collected from the databases of three Italian dermatology units. We performed a clinical evaluation of the morphological characteristics of each assessed melanoma, using both classic ABCDE criteria and the modified ABCDE algorithm for pediatric melanoma to evaluate which of the two algorithms best suited our series. RESULTS: The study population consisted of 39 patients with a histologically confirmed diagnosis of pediatric melanoma. Comparing classic ABCDE criteria with the modified ABCDE algorithm for pediatric melanomas, the modified pediatric ABCDE algorithm was less sensitive than the conventional criteria. Dermoscopically, the most frequent finding was the presence of irregular streaks/pseudopods (74.4%). When evaluating the total number of different suspicious dermoscopy criteria per lesion, 64.1% of the lesion assessments recognized two dermoscopic characteristics, 20.5% identified three, and 15.4% documented four or more assessments. CONCLUSIONS: Contrary to what has always been described in the literature, from a clinical point of view, about 95% of our cases presented in a pigmented and non-amelanotic form, and these data must be underlined in the various prevention campaigns where pediatric melanoma is currently associated with a more frequently amelanotic form. All the pediatric melanomas analyzed presented at least two dermoscopic criteria of melanoma, suggesting that this could be a key for the dermoscopic diagnosis of suspected pediatric melanoma, making it possible to reach an early diagnosis even in this age group.

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.
