RESUMEN
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.
RESUMEN
BACKGROUND: Recently, several case-control studies demonstrated an association between gliptins and bullous pemphigoid (BP) occurrence. However, data on the clinical and immunologic features of gliptin-associated bullous pemphigoid (GABP) are controversial. OBJECTIVE: This study aimed to clinically and immunologically characterize a large cohort of GABP patients to get an insight into the pathophysiology of this emerging drug-induced variant of BP. METHODS: Seventy-four GABP patients were prospectively enrolled and characterized from 9 different Italian dermatology units between 2013 and 2020. RESULTS: Our findings demonstrated the following in the GABP patients: (1) a noninflammatory phenotype, which is characterized by low amounts of circulating and skin-infiltrating eosinophils, is frequently found; (2) immunoglobulin (Ig)G, IgE, and IgA humoral responses to BP180 and BP230 antigens are reduced in frequency and titers compared with those in patients with idiopathic BP; (3) IgG reactivity targets multiple BP180 epitopes other than noncollagenous region 16A. LIMITATIONS: A limitation of the study is that the control group did not comprise only type 2 diabetes mellitus patients with BP. CONCLUSION: GABP patients show peculiar features of anti-BP180 and -BP230 humoral responses, laying the foundation for diagnostic improvements and getting novel insights into understanding the mechanism of BP onset.

Hidradenitis suppurativa (HS) is a chronic, inflammatory, disease of the hair follicle. Intralesional corticosteroid treatment in HS patients has been reported, and while several data described this route of administration as an efficient delivery system, its efficacy is still debated. The aim of this study was to explore the clinical efficacy and the effect on quality of life (QoL) of an innovative intralesional treatment in HS patients. This was an interventional prospective study. The treatment consisted of two intralesional ultrasound-guided injections of triamcinolone plus lincomycin, at baseline and after 2 weeks. Lesions and QoL were evaluated at baseline and at 4 weeks following intralesional therapy. All clinical variables of 36 HS patients significantly improved after 4 weeks. Mean values of the visual analog scale (VAS) pain decreased from 4.6 to 1.5, P = .027. The Bodily Pain (BP) scale of the Short-Form Health Survey (SF-36) significantly improved from 36.2 at baseline to 53.9 at 4-week follow-up (P < .001). On a scale from 0 to 10, over 90% of the patients gave a satisfaction score of 8 or more. This combination of corticosteroids and antibiotics delivered intralesionally seems to be effective, as it improved both patient- and physician-reported outcomes.

Darier's disease is a rare, genetically determined, chronic disorder of keratinization. Characterized clinically by a symmetrical eruption of hypercheratotic papules with predilection for the seborrhoeic areas of the body. Many treatments have been suggested: emollients, topical retinoids, dermoabrasion, topical steroids and intermittent courses of oral antibiotics. Systemic retinoids are usually the treatment of choice. We present a small case series of patients treated with PDT and topical retinoids with good results. This therapeutic modality could represent an alternative to systemic retinoid treatment.
RESUMEN
BACKGROUND: There is currently no definitive cure for urticaria pigmentosa (UP). Psoralen plus ultraviolet A therapy is efficacious in alleviating symptoms and reducing cutaneous lesions. OBJECTIVE: The purpose of this study was to assess the effect of ultraviolet A1 (UVA1) in adult patients with UP and to compare the effectiveness of high-dose (130 J/cm(2)/day for 10 days) and medium-dose (60 J/cm(2)/day for 15 days) UVA1 radiation. METHODS: Ten and 12 adult patients with UP were treated with high-dose or medium-dose UVA1, respectively. The number of skin lesions and dermal mast cells, the presence of Darier's sign, the intensity of pruritus, and quality of life measures were evaluated before, at the end of treatment, and 2 and 6 months later. RESULTS: Baseline characteristics were similar among the 2 groups of patients. In the majority of patients, the number of lesions was not significantly reduced. However, the number of mast cells in lesional skin decreased markedly in most patients by the end of treatment, and it remained low for the whole study period. Pruritus and quality of life improved considerably by the end of treatment, and the improvement was maintained during the 6-month follow up. No significant differences were observed between patients receiving high- or medium-dose UVA1. CONCLUSIONS: UVA1 phototherapy ameliorates both objective and subjective symptoms of adult patients with UP and induces long-term remission in most cases. Medium-dose UVA1 appears at least as effective as high-dose UVA1.
