Gender differences in adult atopic dermatitis and clinical implication: Results from a nationwide multicentre study.

BACKGROUND: Atopic dermatitis (AD) is a common inflammatory skin disease that affects both children and adults. However, limited research has been conducted on gender differences in AD. OBJECTIVES: This study aimed to assess gender differences in adult AD patients, focusing on demographic and clinical features, comorbidities and treatment approaches. METHODS: In this multicentre, observational, cross-sectional study, we enrolled 686 adult patients with AD (357 males and 329 females). For each patient, we collected demographic data (age and sex), anthropometric measurements (weight, height, hip circumference, waist circumference and waist-to-hip ratio), clinical information (onset age, disease duration, severity, itching intensity, impact on quality of life) and noted comorbidities (metabolic, atopic and other). We recorded past and current topical and systemic treatments. We analysed all collected data using statistical techniques appropriate for both quantitative and qualitative variables. Multiple correspondence analysis (MCA) was employed to evaluate the relationships among all clinical characteristics of the patients. RESULTS: We found no differences in age at onset, disease duration, severity and quality of life impact between males and females. Males exhibited higher rates of hypertriglyceridaemia and hypertension. No significant gender differences were observed in atopic or other comorbidities. Treatment approaches were overlapping, except for greater methotrexate use in males. MCA revealed distinct patterns based on gender, disease severity, age of onset, treatment and quality of life. Adult males with AD had severe disease, extensive treatments and poorer quality of life, while adult females had milder disease, fewer treatments and moderate quality of life impact. CONCLUSIONS: Our study reveals that gender differences in adult AD patients are largely due to inherent population variations rather than disease-related disparities. However, it highlights potential undertreatment of females with moderate AD and quality of life impact, emphasizing the need for equitable AD treatment. JAK inhibitors may offer a solution for gender-based therapeutic parity.

The Pacman Flap and Its Modifications for Reconstruction of Skin Cancer Surgical Wounds on the Scalp and Other Body Areas: A Review of 23 Cases / El colgajo Pacman y sus modificaciones para la reconstrucción de heridas quirúrgicas oncológicas en el cuero cabelludo y otras áreas corporales: revisión de 23 casos

Background The Pacman flap is a modified V-Y advancement flap that showed to be versatile in repairing surgical and non-surgical wounds. Indeed, this flap has been used in any anatomical localization, except for the scalp, where its use has not been reported. Moreover, the versatility of the Pacman flap can be enhanced by applying simple modifications to its original design. Materials and methods A case-series of 23 patients whose surgical breaches were repaired using standard or modified Pacman flap were included in this retrospective study. Results Most patients were male (65.2%) with a median age of 75.7 years. Squamous cell carcinoma was the tumor most commonly removed (60.9%), while scalp and face were the most frequent localizations (30.4%). Although 18 flaps were sculpted in the traditional Pacman shape, 5 were modified to fit the defect and localization. Complications occurred in 30% of flaps, but all of them were minor except for 1 extended necrosis. Conclusions The Pacman flap can be used to repair surgical wounds localized in any body area, including the scalp. Three modifications can enhance the versatility of the flap and offer new repair options to dermatologic surgeons (AU)

Comorbidities and treatment patterns in adult patients with atopic dermatitis: results from a nationwide multicenter study.

Adult atopic dermatitis (adult AD) is a systemic inflammatory disorder, whose relationship with immune-allergic and metabolic comorbidities is not well established yet. Moreover, treatment of mild-to-moderate and severe atopic dermatitis needs standardization among clinicians. The aim of this study was to evaluate the distribution of comorbidities, including metabolic abnormalities, rhinitis, conjunctivitis, asthma, alopecia and sleep disturbance, according to severity of adult AD, and describe treatments most commonly used by Italian dermatologists. Retrospective, observational, nationwide study of adult patients over a 2-year period was performed. Clinical and laboratory data were obtained through review of medical records of patients aged ≥ 18 years, followed in 23 Italian National reference centres for atopic dermatitis between September 2016 and September 2018. The main measurements evaluated were disease severity, atopic and metabolic comorbidities, treatment type and duration. Six-hundred and eighty-four adult patients with AD were included into the study. Atopic, but not metabolic conditions, except for hypertension, were significantly associated with having moderate-to-severe AD in young adult patients. Disease duration was significantly associated with disease severity. Oral corticosteroids and cyclosporine were the most widely used immunosuppressant. Our study seems confirm the close relationship between adult AD and other atopic conditions, further long-term cohort studies on patients affected by adult AD need to be performed to evaluate the complex relationship between adult AD disease severity and metabolic comorbidities.

Dupilumab therapy of atopic dermatitis of the elderly: a multicentre, real-life study.

BACKGROUND: Treatment of moderate-to-severe atopic dermatitis (AD) in the elderly may be challenging, due to side-effects of traditional anti-inflammatory drugs and to comorbidities often found in this age group. Furthermore, efficacy and safety of innovative drugs such as dupilumab are not yet well known. OBJECTIVES: A multicentre retrospective, observational, real-life study on the efficacy and safety of dupilumab was conducted in a group of patients aged ≥65 years and affected by severe AD. Their main clinical features were also examined. METHODS: Data of elderly patients with severe (EASI ≥24) AD treated with dupilumab at label dosage for 16 weeks were retrospectively collected. Treatment outcome was assessed by comparing objective (EASI) and subjective (P-NRS, S-NRS and DLQI) scores at baseline and after 16 weeks of treatment. RESULTS: Two hundred and seventy-six patients were enrolled in the study. They represented 11.37% of all patients with severe AD. Flexural eczema was the most frequent clinical phenotype, followed by prurigo nodularis. The coexistence of more than one phenotype was found in 63/276 (22.82%) subjects. Data on the 16-week treatment with dupilumab were available for 253 (91.67%) patients. Efficacy of dupilumab was demonstrated by a significant reduction of all the scores. No statistically significant difference regarding efficacy was found in elderly patients when compared to the group of our AD patients aged 18-64 years, treated with dupilumab over the same period. Furthermore, only 18 (6.52%) patients discontinued the drug due to inefficacy. Sixty-one (22.51%) patients reported adverse events, conjunctivitis and flushing being the most frequent. One (0.36%) patient only discontinued dupilumab due to an adverse event. CONCLUSIONS: Therapy with dupilumab led to a significant improvement of AD over a 16-week treatment period, with a good safety profile. Therefore, dupilumab could be considered as an efficacious and safe treatment for AD also in the elderly.

Real-life experience on effectiveness and safety of dupilumab in adult patients with moderate-to-severe atopic dermatitis.

BACKGROUND: Dupilumab, a fully human monoclonal antibody targeting the alpha subunit of IL-4 was recently approved for the treatment of moderate-to-severe atopic dermatitis (AD) in adult patients. OBJECTIVE: To assess dupilumab effectiveness and safety in adults with moderate-to-severe AD in a real-life Italian multicentre retrospective cohort. METHODS: Adult moderate-to-severe AD patients, referring to 39 Italian centers, received dupilumab in the context of a national patient access program. Disease assessment was performed at baseline, after 4 and 16 weeks of treatment using Eczema-Area-and-Severity-Index (EASI) score, itch and sleep numerical-rating-score (itch-NRS, sleep-NRS) and Dermatology-Life-Quality-Index (DLQI). RESULTS: A total of 109 (71 M/38F) patients was studied. There was a significant reduction in EASI score, itch-NRS, sleep-NRS and DLQI from baseline to week 4 and a further significant decline to week 16. EASI 50, EASI75 and EASI90 were achieved by 59.6%, 28.4% and 9.3% of patients at 4 weeks and by 87.2%, 60.6% and 32.4% of them at 16 weeks, respectively. Adverse events were experienced by 19.2% (21/109) of the patients and they were all mild in intensity, being conjunctivitis the most common side effect. CONCLUSIONS: Dupilumab significantly improved disease severity, pruritus, sleep loss and quality of life with an acceptable safety profile.

HIDRAdisk: validation of an innovative visual tool to assess the burden of hidradenitis suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disease characterized by painful inflamed nodules, recurrent abscesses and fistulas located in apocrine gland-bearing body sites. The negative impact of HS on patient's quality of life (QoL) has been reported to be greater than other dermatologic conditions as psoriasis and atopic eczema, and its improvement is an important goal in disease management. Nowadays, there are no specific validated QoL instruments available for HS and generic dermatologic questionnaires are used. OBJECTIVE: The objective of this study was to demonstrate the validity, reliability and responsiveness of HIDRAdisk, a new innovative tool designed for rapid assessment of HS burden and, at the same time, an intuitive graphic visualization of the measurement outcome. METHODS: A multicentre, longitudinal, observational study was conducted to validate the HIDRAdisk compared with other validated questionnaires [Skindex-16, Dermatology Life Quality Index (DLQI), Work Productivity and Activity Impairment-General Health (WPAI:GH)] and to evaluate its correlation with disease severity in Italian patients with any degree of HS severity, as measured by Hurley stage and HS Physician Global Assessment (HS-PGA). RESULTS: A total of 140 patients (59% women; mean age 34.9 ± 11.0 years) were enrolled in 27 dermatologic centres. HIDRAdisk showed a strong correlation with Skindex-16 and DLQI, and a good one with WPAI:GH (correlation coefficient: 0.7568, 0.6651 and 0.5947, respectively) and a statistically significant correlation with both Hurley stage and HS-PGA. Very good internal consistency (Cronbach coefficient >0.80; intraclass correlation coefficient >0.6), with correlation between the 10 items, good test-retest reliability (Spearman correlation coefficient, 0.8331; P < 0.0001) and responsiveness to changes were demonstrated. CONCLUSION: Our study shows that HIDRAdisk, a short and innovative visual HS QoL instrument, has been psychometrically validated in Italian language and it may help improve the management of HS once implemented in routine clinical practice.

Thermal alterations in patients with inflammatory diseases: a comparison between psoriatic and rheumatoid arthritis.

Functional infrared imaging (fIRI) is used to provide information on circulation, thermal properties and thermoregulatory function of the cutaneous tissue in several clinical settings. This study aims to evaluate the application of fIRI in rheumatoid arthritis (RA) assessment, evaluating the thermoregulatory alterations due to joint inflammation in RA patients both in basal conditions and after a mild functional (isometric) exercise, using the same protocol we projected in our recent work on psoriatic arthritis (PsA); fIRI outcomes were compared with those provided by power-Doppler ultrasonography. Ten patients with RA and 11 healthy controls were enrolled in the study. The cutaneous temperature dynamics of 20 regions of interest located on the dominant hand were recorded by means of high-resolution thermal imaging at baseline and after a functional exercise. RA patients showed lower thermal parameters compared to healthy controls, suggesting that the RA-related inflammatory state alters the normal thermal properties of the skin overlying inflamed joints. These results are different from PsA data observed in the previous study. fIRI applied to the study of the response to a functional stimulus may represent an innovative, non-invasive, and operator-independent method for the assessment of early RA.

Extremely low-frequency electromagnetic fields accelerates wound healing modulating MMP-9 and inflammatory cytokines.

OBJECTIVES: In our previous reports, we have demonstrated that extremely low-frequency electromagnetic fields (ELF-EMF) exposure enhances the proliferation of keratinocyte. The present study aimed to clarify effects of ELF-EMF on wound healing and molecular mechanisms involved, using a scratch in vitro model. MATERIALS AND METHODS: The wounded monolayer cultures of human immortalized keratinocytes (HaCaT), at different ELF-EMF and Sham exposure times were monitored under an inverted microscope. The production and expression of IL-1ß, TNF-α, IL-18 and IL-18BP were measured by enzyme-linked immunosorbent assay and quantitative real-time PCR. The activity and the expression of matrix metalloproteinases (MMP)-2/9 was evaluated by zymography and Western blot analysis, respectively. Signal transduction proteins expression (Akt and ERK) was measured by Western blot. RESULTS: The results of wound healing in vitro assay revealed a significant reduction of cell-free area time-dependent in ELF-EMF-exposed cells compared to Sham condition. Gene expression and release of cytokines analysed were significantly increased in ELF-EMF-exposed cells. Our results further showed that ELF-EMF exposure induced the activity and expressions of MMP-9. Molecular data showed that effects of ELF-EMF might be mediated via Akt and ERK signal pathway, as demonstrated using their specific inhibitors. CONCLUSIONS: Our results highlight ability of ELF-EMF to modulate inflammation mediators and keratinocyte proliferation/migration, playing an important role in wound repair. The ELF-EMF accelerates wound healing modulating expression of the MMP-9 via Akt/ERK pathway.

Psoriasis and migraine.

BACKGROUND: Psoriasis and migraine share several pathogenetic mechanisms due to systemic inflammation, which increase the risk of developing cardiovascular disease. OBJECTIVE: Our aim was to investigate the prevalence of migraine with (MA) and without aura (MO) in the psoriatic population, investigating a possible new comorbidity of the psoriatic disease. METHODS: We referred 68 psoriatic patients to a nine questions survey formulated on the basis of the International Headache Society (IHS) diagnostic criteria for migraine. Then, in the case of MA, the mean monthly number of migraine crises was assessed. Data of psoriatic patients were then compared with those of a psoriasis-free control group composed of 235 migraine patients (with and without aura). RESULTS: A clinical diagnosis of migraine was performed in 32 psoriasis patients with a great prevalence in women (F: 87.50% - M: 12.5%). Moreover, we found a much higher prevalence (62.5%) of MA, with the remaining 37.5% diagnosed with MO. Comparing the prevalence of MA between psoriasis + migraine patients and the control group we observed a statistical significative difference (P < 0.0001); furthermore, the number of MA crises was significantly higher (P < 0.0001) in patients with psoriasis with respect to the MA control group. CONCLUSIONS: We showed a significant association between psoriasis and migraine, especially MA, probably due to common pathogenetic mechanisms, but further studies are needed to assess their interplay in developing cardiovascular diseases.

"Nail loss after teriflunomide treatment: A new potential adverse event".

Nail loss might represent a new, reversible, adverse event associated with teriflunomide treatment. It shares close analogies with hair loss and thinning, known adverse events of teriflunomide. MS specialists should be aware of this possibility and evaluate treatment discontinuation.
