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.

Potential drug-drug interactions with mitogen-activated protein kinase (MEK) inhibitors used to treat melanoma.

INTRODUCTION: The management of patients with BRAF-mutated advanced melanoma who are undergoing targeted therapy with MEK inhibitors can be complicated by the co-administration of multiple medications, which can give rise to drug-drug interactions of clinical significance. COVERED AREAS: Our review presents a comprehensive analysis of the pharmacokinetic and pharmacodynamic interactions of the three approved for advanced melanoma MEK inhibitor drugs - binimetinib, cobimetinib, and trametinib. MEDLINE (PubMed) was utilized for the literature search, comprising clinical studies, observational studies, and preclinical research. The review discusses the impact of these interactions on efficacy and safety of the treatments and differentiates between interactions supported by pharmacokinetic or pharmacodynamic mechanisms, those encountered in clinical practice, and those observed in preclinical studies. EXPERT OPINION: Physicians should be aware about potential benefits, but also increased toxicity caused by drug interactions between MEK inhibitors and other drugs in the management of patients with metastatic melanoma.

Moderate-to-severe atopic dermatitis in adolescents treated with dupilumab: A multicentre Italian real-world experience.

BACKGROUND: Moderate-to-severe atopic dermatitis (AD) in the adolescence is a high burden disease, and its treatment can be very challenging due to paucity of approved systemic drugs for this age and their side-effects. Dupilumab was recently approved for treatment of adolescent AD. OBJECTIVES: A multicentre, prospective, real-world study on the effectiveness and safety of dupilumab in adolescents (aged from ≥12 to <18 years) with moderate-to-severe AD was conducted. The main AD clinical phenotypes were also examined. METHODS: Data of adolescents with moderate-to-severe AD treated with dupilumab at label dosage for 16 weeks were collected. Treatment outcome was assessed by EASI, NRS itch, NRS sleep loss and CDLQI scores at baseline and after 16 weeks of treatment. The clinical scores were also evaluated according to clinical phenotypes. RESULTS: One hundred and thirty-nine adolescents were enrolled in the study. Flexural eczema and head and neck eczema were the most frequent clinical phenotypes, followed by hand eczema and portrait-like dermatitis. Coexistence of more than 1 phenotype was documented in 126/139 (88.5%) adolescents. Three patients (2.1%) contracted asymptomatic SARS-CoV-2 infection and 1 of the discontinued dupilumab treatment before the target treatment period. A significant improvement in EASI, NRS itch, NRS sleep loss and CDLQI was observed after 16 weeks of treatment with dupilumab. This outcome was better than that observed in clinical trials. Dupilumab resulted effective in all AD phenotypes, especially in diffuse eczema. Twenty-eight (20.1%) patients reported adverse events, conjunctivitis and flushing being the most frequent. None of patients discontinued dupilumab due to adverse event. CONCLUSIONS: Dupilumab in adolescent AD showed excellent effectiveness at week 16 with consistent improvement of all clinical scores. Moreover, dupilumab showed a good safety profile also in this COVID-19 pandemic era.

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.

How to fight SARS-COV-2 vaccine hesitancy in patients suffering from chronic and immune-mediated skin disease: four general rules.

All public health ministries have implemented strategies to contain the spread of COVID-19 worldwide. Vaccines against SARS-CoV-2 still represent the most effective weapon to combat the circulation of the virus, in order to decrease the impact of COVID-19 on the general health of the population, to prevent the emergence of new SARS-CoV-2 variants and avoid excessive hospitalization. However, the success of a vaccination campaign largely depends on the penetrance of the message addressed to general population, which takes on an even more strategic value when vaccine candidates suffer from chronic diseases. In this view, patients suffering from immune-mediated skin diseases could represent a "weak link in the vaccine chain." Our main objective is to focus attention on four main elements in support of vaccination strategy in order to promote the patients' awareness to be at highest risk of negative consequences in case of SARS-Cov-2 infection, and to build, strengthen and maintain trust in vaccines' efficacy and safety.

Evidence for a 'window of opportunity' in hidradenitis suppurativa treated with adalimumab: a retrospective, real-life multicentre cohort study.

BACKGROUND: The anti-tumour necrosis factor (TNF)-α adalimumab is the only licenced biologic for moderate-to-severe hidradenitis suppurativa (HS). No predictors of response have been identified so far. OBJECTIVES: To identify clinical parameters predicting response to adalimumab and confirm its efficacy/safety. METHODS: The data of 389 patients with HS treated with adalimumab in 21 Italian centres were reviewed. Sex, age at onset/diagnosis/baseline, body mass index, smoking, phenotype, previous treatments, concomitant antibiotics and 'therapeutic delay', defined as the time from HS onset to adalimumab initiation, were assessed. Response to adalimumab and its impact on quality of life (QoL) were evaluated using the Hidradenitis Suppurativa Clinical Response (HiSCR) and the Dermatology Life Quality Index (DLQI) or the Visual Analogue Scale for pain (VAS pain), respectively. Logistic regression analysis was performed. RESULTS: The therapeutic delay correlated to lack of response to adalimumab at week 16 [odds ratio (OR) 1·92 for therapeutic delay > 10 years; 95% confidence interval (CI) 1·28-2·89; P = 0·0016). HiSCR was achieved in 43·7% and 53·9% patients at week 16 and 52, respectively. Significant reductions in both DLQI and VAS pain were found between week 16 vs. baseline (P < 0·0001 for both) and week 52 vs. baseline (P < 0·0001 for both). Previous immunosuppressants inversely correlated to HiSCR at week 52 (OR = 1·74, 95% CI 1·04-2·91, P = 0·0342). CONCLUSIONS: Inverse correlation between therapeutic delay and clinical response was found, supporting early adalimumab use and providing evidence for a 'window of opportunity' in HS treatment. Adalimumab efficacy and safety were confirmed, along with patients' QoL improvement. Immunosuppressants could negatively influence the response to adalimumab inducing a switch to non-TNF-α-driven pathways.

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.

Lymecycline vs. clindamycin plus rifampicin in hidradenitis suppurativa treatment: clinical and ultrasonography evaluation.

BACKGROUND: Antibiotic therapy remains the first-line treatment for hidradenitis suppurativa (HS). However, literature data on its comparative clinical efficacy and safety are limited. AIM: To investigate the efficacy of tetracycline (lymecycline 300 mg daily) vs. the combination therapy clindamycin and rifampicin (600 mg plus 600 mg daily) by evaluating and comparing the clinical response at the end of antibiotic treatment (10 weeks). METHODS: The study retrospectively analysed 52 patients divided in two groups of 26 patients: Group A received lymecycline and Group B received clindamycin plus rifampicin for 10 weeks. Subjects had mild, moderate and severe HS. The clinical and ultrasonography extent of disease was measured by the Hurley Score, Sonographic Score of Hidradenitis Suppurativa, International Hidradenitis Suppurativa Severity Score System (IHS4), pain visual analogue scale (pain VAS) and Dermatology Life Quality Index (DLQI). The primary outcome was the clinical response at the end of the antibiotic treatment period, according to the Hidradenitis Suppurativa Clinical Response measure. RESULTS: Both groups showed a significant improvement in IHS4, pain VAS and DLQI from baseline, but this was more marked in Group A. Reductions in nodule counts were similar between the two groups, whereas the number of abscesses and draining tunnels decreased more in Group B. Disease-free survival was similar between the two groups. CONCLUSION: Lymecycline monotherapy and clindamycin plus rifampicin combination are both effective treatments for patients with moderate-severe HS. Nodular-type HS seems to respond better to lymecycline, whereas the abscess/tunnel type seems to respond better to clindamycin plus rifampicin.

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.

Brodalumab for the treatment of moderate-to-severe plaque-type psoriasis: a real-life, retrospective 24-week experience.

BACKGROUND: Brodalumab was efficacious and safe in moderate-to-severe plaque-type psoriasis in the AMAGINE trials; published reports under real-life conditions are limited. OBJECTIVES: To evaluate the effectiveness and safety of brodalumab in patients with moderate-to-severe plaque-type psoriasis in a real-world setting. METHODS: This observational, retrospective study enrolled adult patients (≥18 years) with moderate-to-severe plaque-type psoriasis who underwent 24 weeks of treatment with brodalumab at 17 Italian dermatological centres. Baseline data included demographics, comorbidities, age of onset and duration of psoriasis and previous treatments. Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA), static PGA of Genitalia, Dermatology Life Quality Index and patient satisfaction were assessed at weeks 0, 4, 12 and 24; adverse events were recorded. RESULTS: Seventy-eight patients (mean age 47.9 years, 71.8% male, average disease duration 16.8 years) were enrolled. A rapid and significant reduction in mean PASI score was observed after 4 weeks of treatment, decreasing further at weeks 12 and 24 (all P < 0.0001 vs. baseline). A higher number of cardiometabolic comorbidities and previous therapies were negatively associated with the achievement of PASI 90 at all assessments. Brodalumab was effective in bio-experienced patients, including those who had failed on anti-interleukin (IL)-17 therapies. Quality of life and patient satisfaction increased significantly during treatment (P < 0.0001 and P < 0.01 vs. baseline, respectively). Treatment was interrupted in 9 (11.5%) patients due to adverse events (n = 4), lack of efficacy (n = 3), lost to follow-up (n = 1) and surgical procedure (n = 1). CONCLUSIONS: Brodalumab is effective and safe in the treatment of moderate-to-severe psoriasis in a real-world setting, including in patients with failure to anti-IL17 therapies.
