RESUMO
Obesity is a chronic inflammatory condition that has been associated with different types of cancer. However, its role in melanoma incidence, progression, and response to immune-checkpoint-inhibitors (ICI) is still controversial. On the one hand, increased levels of lipids and adipokines can promote tumor proliferation and several genes associated with fatty acid metabolism have been found to be upregulated in melanomas. On the other hand, immunotherapy seems to be more effective in obese animal models, presumably due to an increase in CD8 + and subsequent decrease in PD-1 + T-cells in the tumor microenvironment. In humans, several studies have investigated the role of BMI (body mass index) and other adiposity-related parameters as potential prognostic markers of survival in advanced melanoma patients treated with ICI. The aim of this research has been to systematically review the scientific literature on studies evaluating the relationship between overweight/obesity and survival outcomes in patients with advanced melanoma treated with ICI and to perform a meta-analysis on those sharing common characteristics. After screening 1070 records identified through a literature search, 18 articles assessing the role of BMI-related exposure in relation to survival outcomes in ICI-treated patients with advanced melanoma were included in our review. In the meta-analysis of the association between overweight (defined as BMI>25 or BMI 25-30), overall survival (OS), and progression free survival (PFS), 7 studies were included, yielding a summary HR of 0.87 (95% CI: 0.74-1.03) and 0.96 (95% CI: 0.86-1.08), respectively. Our results show that, despite few suggestive findings, the use of BMI as a valuable predictor of melanoma patients' survival in terms of PFS and OS should not be currently recommended, due to the limited evidence available.

Real-world data on the long-term effectiveness of the anti-IL17 agent secukinumab in treating moderate-to-severe Hidradenitis suppurativa (HS) are lacking. In this study, 24 patients with moderate-severe HS received five weekly subcutaneous injections followed by maintenance doses every 4 weeks. Primary outcomes included HiSCR, IHS4 reduction, and DLQI measures assessed at 12-week intervals. The median secukinumab drug survival was 16.0 months (range 3-51), with a 56.5% maximal response rate at 6 months and dropout exceeding 40% at 1 year. Baseline disease burden emerged as a key predictor of treatment response, overshadowing factors like sex or BMI. Prior systemic steroid use negatively impacts drug survival. The study underscores the critical 6-month window for assessing treatment efficacy, emphasizing the importance of initial induction dosing. Additionally, the newly developed scoring system, IHS4-55, showed analogies to the older HiSCR score in capturing treatment response. In this real-life scenario, challenges persist in HS management, necessitating innovative therapeutic approaches and predictive markers.

Noma, or Cancrum oris, is a severe and rapidly progressing gangrenous infection that primarily affects the face. It is most commonly observed in children living in impoverished conditions, especially in sub-Saharan Africa. Rapid diagnosis and early management are crucial to prevent devastating consequences, such as functional limitations and serious psychological repercussions. Herein, we present a case of an 8-month-old child affected by noma, whose positive outcome is attributed to the prompt recognition by healthcare personnel. In our patient, the condition was likely related to malnutrition and the preceding extraction of a deciduous tooth reported by the mother and probably associated with a traditional Ugandan practice called Ebiino. This is the second case reported in Uganda, and given the limited healthcare access in most of the country, coupled with the high prevalence of poverty and other predisposing factors, it becomes evident that the incidence of noma is underestimated. Noma, as a neglected disease, requires greater awareness within communities and among healthcare professionals. A collective effort is needed to significantly reduce risk factors and promote prevention of this life-threatening disease.

Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy (SHML), is a rare subtype of reactive histiocytosis which is seldom associated with Hodgkin's and non-Hodgkin's lymphomas. To date, the coexistence in the same patient of extra nodal SHML and primary cutaneous B-cell lymphoma (PCBCL) has been reported in the literature, as metachronous diagnosis in the anatomical area of the original PCBCL or synchronous occurrence in the same lesions. However, no data have been published as for synchronous occurrence of the two pathological entities in distinct anatomical sites. Herein, we report the first ever described synchronous occurrence of PCBCL and SHML, detected in distinct lesions, affecting the same patient. The complete resolution of the patient's PCBCL after rituximab treatment and the concomitant regression of SHML suggest that this clinically benign reactive histiocytic proliferation, potentially triggered by the lymphoma microenvironment itself, may take place not only in the site of the PCBCL lesion, but also in other distant areas not directly affected by the primary cutaneous lymphoma.

INTRODUCTION: Surgery represents the primary treatment option for cutaneous squamous cell carcinoma (cSCC) aiming for complete tumor resection (R0). Recurrence and metastasis significantly affect survival and outcomes, and poorly differentiated (G3) cSCC is associated with a higher risk of recurrence. However, the specific clinical and histopathological features that predict recurrence and progression in G3-cSCC remain unclear. METHODS: A retrospective analysis was conducted on a series of patients with primary G3-cSCC diagnosed at the Turin University Hospital between January 2016 and January 2021. After independent histological revision, logistic regression models were used to identify clinico-pathological predictors of cutaneous recurrence, lymphnode/metastatic progression, and both types of progression. RESULTS: Among the 161 G3-cSCC patients, 80.1% (129/161) showed no signs of local recurrence or metastatic progression, while 19.9% (32 patients) had progressed. In the univariate logistic regression, tumor clinical diameter, depth of infiltration (DOI), and lymphovascular invasion (LVI) were identified as significant predictors across the various types of progression (p < 0.05). In the context of multivariate logistic regression, distinct models proved to be significant. For skin recurrence, a 3-variable model incorporating DOI (OR 1.16, 95% CI, 1.01-1.35, p = 0.050), LVI (OR 3.61, 95% CI, 1.11-11.8, p = 0.034), and desmoplasia (OR 3.45, 95% CI, 1.25-9.5, p = 0.017) was selected. Regarding lymphnode/metastatic progression, a 3-variable model combining pT2 (OR 6.10, 95% CI, 1.15-32.35, p = 0.034), pT3 (OR 14.33, 95% CI, 2.79-73.63, p = 0.001), and LVI (OR 3.86, 95% CI, 1.10-13.62, p = 0.036) was identified. Lastly, a 2-variable model for both types of progression consisted of vertical tumor thickness (OR 5.45, 95% CI, 1.11-27.32, p = 0.039) and LVI (OR 1.15, 95% CI, 1.04-1.26, p = 0.006). CONCLUSION: Tumor size, DOI, and LVI were significant predictors of recurrence and metastatic progression. Notably, the size of histologically defined tumor-free margins did not affect the risk of recurrence, whilst LVI emerged as a key predictor of all forms of progression. These findings provide insights into risk stratification and suggest that close monitoring and potential adjuvant therapies, such as radiation therapy, may be necessary especially for patients with lymphovascular involvement.

BACKGROUND: Managing a pregnant patient with chronic spontaneous urticaria (CSU) is often challenging. Recent data have shown that most CSU treatments in pregnant patients are second-generation H1 antihistamines (sgAHs), while data on the safety of omalizumab are scant. OBJECTIVES: To evaluate, in a routine clinical practice setting, the efficacy and safety of omalizumab in patients with severe CSU refractory to sgAHs who either became pregnant during treatment or who started the drug during pregnancy. METHODS: We conducted a retrospective study of women aged ≥ 18â years who were pregnant, who received one or more doses of omalizumab at any time during their pregnancy or who were taking omalizumab at the time of, or in the 8 weeks before, conception. RESULTS: Twenty-nine pregnant patients were evaluated: 23 (79%) conceived a child while taking omalizumab (group A), while 6 (21%) started omalizumab treatment during pregnancy (group B). Among patients in group A, we observed 23 births (21 liveborn singletons and 1 liveborn twin pair) and 1 miscarriage. Fifteen (65%) patients discontinued omalizumab after confirming their pregnancy, while eight (35%) were exposed to omalizumab during their entire pregnancy. In group B, omalizumab was introduced at a mean (SD) 10.83 (3.60) weeks' gestation and all patients were exposed to it until the end of pregnancy. In this group, there were seven liveborn infants (five singletons and one twin pair). No adverse events, pregnancy complications or congenital anomalies in newborns were recorded in either group. CONCLUSIONS: Omalizumab for CSU treatment before and during pregnancy does not appear to have negative effects on maternal or fetal outcomes.

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.
RESUMO
BACKGROUND: The survival benefit of sentinel lymph node biopsy (SLNB) in immunocompetent and immunosuppressed patients with high-risk cutaneous squamous cell carcinoma (cSCC) has not been established. OBJECTIVE: To determine whether SLNB improves disease-specific survival (DSS) in high-risk cSCC. Secondary objectives were to analyse disease-free survival, nodal recurrence-free survival and overall survival (OS). METHODS: Multicentre, retrospective, observational cohort study comparing survival outcomes in immunosuppressed and immunocompetent patients treated with SLNB or watchful waiting. Inverse probability of treatment weighting was used to adjust for possible confounding effects. RESULTS: We studied 638 tumours in immunocompetent patients (SLNB n = 42, observation n = 596) and 173 tumours in immunosuppressed patients (SLNB n = 28, observation n = 145). Overall, SLNB was positive in 15.7% of tumours. SLNB was associated with a reduced risk of nodal recurrence (NR) (hazard ratio [HR], 0.05 [95% CI, 0.01-0.43]; p = 0.006), disease specific mortality (HR, 0.17 [95% CI, 0.04-0.72]; p = 0.016) and all-cause mortality (HR, 0.33 [95% CI, 0.15-0.71]; p = 0.004) only in immunocompetent patients. CONCLUSIONS: SLNB was associated with improvements in NR, DSS and OS in immunocompetent but not in immunosuppressed patients with high-risk cSCC.

BACKGROUND: There is limited epidemiological evidence on outcomes associated with dupilumab exposure during pregnancy; monitoring pregnancy outcomes in large populations is required. OBJECTIVE: To investigate the potential association between exposure to dupilumab in pregnant women with atopic dermatitis and any adverse pregnancy, neonatal, congenital and post-partum outcomes. METHODS: We performed a multicentre retrospective cohort study across 19 Italian tertiary referral hospital. Childbearing women were eligible if aged 18-49 years and carried out the pregnancy between 1 October 2018 and 1 September 2022. RESULTS: We retrospectively screened records of 5062 patients receiving dupilumab regardless of age and gender, identifying 951 female atopic dermatitis patients of childbearing age, 29 of whom had been exposed to the drug during pregnancy (3%). The median duration of dupilumab treatment prior to conception was 22.5 weeks (range: 3-118). The median time of exposure to the drug during pregnancy was 6 weeks (range: 2-24). All the documented pregnancies were unplanned, and the drug was discontinued in all cases once pregnancy status was reported. The comparison of the study cohort and the control group found no significant drug-associated risk for adverse pregnancy, congenital, neonatal or post-partum outcomes. The absence of a statistically significant effect of exposure on the event was confirmed by bivariate analysis and multivariate analysis adjusted for other confounding factors. CONCLUSIONS: This cohort of pregnant patients exposed to dupilumab adds to the existing evidence concerning the safety of biologic agents in pregnancy. No safety issues were identified regarding the primary outcome assessed. In clinical practice, these data provide reassurance in case of dupilumab exposure during the first trimester. However, the continuous use of dupilumab throughout pregnancy warrants further research.
RESUMO
BACKGROUND: Biologics targeting IL-23 and IL-17 show efficacy and safety in the treatment of moderate-to-severe psoriasis. OBJECTIVE: To investigate drug survival in patients with psoriasis treated with biologics. PATIENTS AND METHODS: We performed a comparative evaluation of the achievement of PASI 90 and PASI ≤ 3 at 16, 28, and 52 weeks along with a DS (drug survival) analysis with IL-17 and IL-23 inhibitors brodalumab, ixekizumab, secukinumab, risankizumab, tildrakizumab, and guselkumab on 1,057 patients. RESULTS: IL-17 inhibitors showed a faster achievement of PASI 90 and PASI ≤ 3 with significant superiority over IL-23 inhibitors at week 16 (p < 0.001; 56% vs. 42% and 70% vs. 59%, respectively). A difference was shown in favor of IL-23 inhibitors regarding DS (p < 0.001), which was 88% at 24 months vs. 75% for IL-17 inhibitors. In multivariate analysis, IL-23 inhibitors (HR 0.54 CI 0.37-0.78, p = 0.001), and male sex (HR 0.57 CI 0.42-0.76, p < 0.001) were all associated with a lower probability of drug interruption. Risankizumab (HR 0.42 CI 0.26-0.69, p = 0.001), guselkumab (HR 0.49 CI 0.24-0.99, p = 0.046), and male sex (HR 0.57 CI 0.43-0.77, p < 0.001) were associated with a lower probability of drug interruption than secukinumab. CONCLUSIONS: IL-23 inhibitors showed the best performance on DS. Overall, the most effective class was IL-17 inhibitors considering the short-term effectiveness, but long-term effectiveness is in favor of anti-IL-23.

BACKGROUND: Alcohol abuse is correlated with the onset and worsening of psoriasis, but its effects, as for smoking, on biological therapies are still poorly investigated. MATERIALS AND METHODS: This study aimed to determine the prevalence of alcohol abuse and other discretionary habits (such as smoking and sedentary lifestyle) in patients with psoriasis treated with topicals, conventional systemic and biologic therapies. The second objective is to investigate the impact of discretionary habits, focusing on alcohol abuse, on the response to biological therapy. To identify alcohol dependence, the CAGE questionnaire was distributed among patients of our clinic. RESULTS: 305 patients were included with 18% at high risk of alcohol abuse. Clinically, guttate psoriasis and psoriatic arthritis were more common in patients at higher risk of alcohol abuse. Furthermore, patients with an alcohol problem who started biological therapy reported a higher PASI than those who drank less. None of the considered variables seemed to correlate with discontinuation of medication or with lower achievement of the analyzed outcomes (PASI100, PASI90, and PASI≤3). There was a stronger association between alcohol dependence and patients receiving conventional therapy than with patients receiving biologics. CONCLUSIONS: The efficacy of biologicals did not seem to be impacted by alcohol consumption, smoking, or sedentary lifestyle.
RESUMO
BACKGROUND: This study aimed to improve the understanding of the prognostic value of tumor mitotic rate (TMR) in cutaneous melanoma and assessed its significance as a predictor for overall, melanoma-specific, and recurrence-free survival. PATIENTS AND METHODS: This is a retrospective multicenter Italian cohort study of 13,016 patients diagnosed with and treated for invasive primary melanoma between 2005 and 2020 with median follow-up of 5.5 years. The survival probability was assessed by Kaplan-Meier method, hazard ratios (HRs), and corresponding 95% confidence interval (CI) of all-cause mortality and recurrence/death by multivariable Cox proportional hazards models. RESULTS: Higher dermal mitoses number was associated with decreased overall survival. Among patients with TMR 0/mm2 , 1/mm2 , 2/mm2 -3/mm2 , 4/mm2 -10/mm2 , and >10/mm2 , 5-year overall survival (OS) was 97.3%, 93.6%, 88.3%, 73.0%, and 60.9%, respectively. In multivariate analyses, compared to TMR of 0/mm2 , HRs for all-cause mortality were 1.35 (95% CI, 1.08-1.68), 1.70 (95% CI, 1.40-2.07), 2.04 (95% CI, 1.67-2.49), and 2.39 (95% CI, 1.90-3.00) for 1 mitoses/mm2 , 2 mitoses/mm2 -3 mitoses/mm2 , 4 mitoses/mm2 -10 mitoses/mm2 , and >10 mitoses/mm2 , respectively. A similar increase in risks was observed in melanoma-specific survival (MSS) and recurrence-free survival (RFS). The HRs for MSS and RFS for the highest compared to the lowest TMR category were 3.01 (95% CI, 2.20-4.11) and 2.26 (95% CI, 1.88-2.73), respectively. Sentinel lymph-node biopsy positivity was significantly associated with TMR increase even with adjustment for several potential confounders. CONCLUSIONS: A clear association was demonstrated between an increasing TMR and decreased OS, MSS, and RFS, suggesting a reconsideration of TMR prognostic role for future inclusion in the melanoma staging system. PLAIN LANGUAGE SUMMARY: The 8th American Joint Committee on Cancer for melanoma staging removed tumor mitotic rate (TMR) from the staging criteria for T1 melanomas, giving way to ulceration and tumor thickness as stronger prognostic predictors. However, it is still recommended that TMR should be assessed and recorded in all primary invasive melanomas. In a large retrospective multicenter study on primary invasive melanomas, we investigated the prognostic value of TMR to assess its significance as survival predictor. Our results showed a clear association between increasing TMR and decreased patients' survival, suggesting that TMR should be considered for inclusion in the melanoma staging system.

Dupilumab effectiveness and safety in treating moderate-to-severe atopic dermatitis (AD) have been demonstrated in open-label studies up to 4 years. Evidence about long-term psychological outcome is lacking. This study evaluates the long-term psychological outcome of moderate-to-severe AD patients continuously treated with Dupilumab up to 3 years. A prospective observational real-life study was conducted at an Italian tertiary centre from January 2019 to September 2022. Measures of disease severity and psychological outcomes were assessed at baseline, after 4, 8, 12, 24 and 36 months. A total of 382 moderate-to-severe AD patients were included. After 36 months, EASI-75 and EASI-90 were achieved by 91.8% and 77.2% of participants. Significant improvement (p < 0.001; ω2 = 0.18-0.84) in objective and patient-reported measures of disease severity and in the psychological condition were observed after 4 months of treatment and maintained up to 36 months. Longitudinal analysis of interactions of demographic and clinical features found subgroups of patients who did not reported psychological improvement over the study period notwithstanding the positive clinical response. Long-term improvement in the psychological outcome of moderate-to-severe AD patients continuously treated with Dupilumab is confirmed up to 3 years, supporting its wide use in this population. Between-subject differences in the psychological outcome irrespective of clinical response observed in this study foster the biopsychosocial approach in the clinical management of these patients.

BACKGROUND: The COVID-19 pandemic-related health crisis has imposed measures aimed at reducing the overcrowding of health facilities, by developing telemedicine and by forcing many sexually transmitted infection (STI) clinics to book appointments by telephone. In this work, we evaluate the performance of the nursing telephone triage system, introduced in the major STI center in Northwest Italy, for the adequacy of clinical pathways for of symptomatic STI patients. METHODS: From January to March 2021, all symptomatic patients wishing to access the CeMuSS center first underwent nurse-led telephone triage. Symptoms suggestive of STIs were further classified into four syndromic presentations: cutaneous neoformations, genital and oral ulcers, anogenital discharge, and finally other dermatological manifestations. All other clinical pictures were properly managed and eventually referred to other centers and not considered in the analysis. During the following medical examinations, the concordance between presumptive syndromic diagnosis and confirmed clinical diagnosis were recorded. Cohen k test was used to assess concordance. RESULTS: According to the Cohen k test, a good concordance between telephone presumptive diagnoses and medical clinical assessment was found (73.79% with a k = 0.611), whereas only a scarcely acceptable concordance between expected and real waiting time was established (75.51%, k = 0.34). CONCLUSIONS: Concordance between nursing syndromic diagnosis and syndromic medically confirmed diagnosis is good from a clinical point of view but there is a limitation when considering a public health perspective. An optimal training of nurses may improve the method of telephone triage. For future ongoing emergencies, the implementation of telemedicine with accurate patient management systems is mandatory.

The lentiginous spread of melanocytes into the hair follicle can be observed in a number of benign melanocytic neoplasms such as in nevi but also in sun-induced melanocytic hyperplasia and melanoma. The follicular colonization by melanocytes in melanoma is classified into three distinct patterns: primary follicular melanoma, melanoma with folliculotropism, and invasive melanoma arising from melanoma in situ with folliculotropism. The role of follicular colonization in melanoma pathologic staging is still a matter of debate though the description of the latter has been recommended by the International Collaboration on Cancer Reporting. In this review, we will discuss the role of follicular colonization in melanoma and melanocytic nevi as well as the facts and controversies regarding this topic.

BACKGROUND: The prognostic impact of variant allele frequency (VAF) on clinical outcome in BRAFV600 mutated metastatic melanoma patients (MMPs) receiving BRAF (BRAFi) and MEK inhibitors (MEKi) is unclear. MATERIALS AND METHODS: A cohort of MMPs receiving first line BRAFi and MEKi was identified by inspecting dedicated databases of three Italian Melanoma Intergroup centres. VAF was determined by next generation sequencing in pre-treatment baseline tissue samples. Correlation between VAF and BRAF copy number variation was analysed in an ancillary study by using a training and a validation cohort of melanoma tissue samples and cell lines. RESULTS: Overall, 107 MMPs were included in the study. The VAF cut-off determined by ROC curve was 41.3%. At multivariate analysis, progression-free survival (PFS) was significantly shorter in patients with M1c/M1d [HR 2.25 (95% CI 1.41-3.6, p < 0.01)], in those with VAF >41.3% [HR 1.62 (95% CI 1.04-2.54, p < 0.05)] and in those with ECOG PS ≥1 [HR 1.82 (95% CI 1.15-2.88, p < 0.05)]. Overall survival (OS) was significantly shorter in patients with M1c/M1d [HR 2.01 (95% CI 1.25-3.25, p < 0.01)]. Furthermore, OS was shorter in patients with VAF >41.3% [HR 1.46 (95% CI 0.93-2.29, p = 0.06)] and in patients with ECOG PS ≥1 [HR 1.52 (95% CI 0.94-2.87, p = 0.14)]. BRAF gene amplification was found in 11% and 7% of samples in the training and validation cohort, respectively. CONCLUSIONS: High VAF is an independent poor prognostic factor in MMP receiving BRAFi and MEKi. High VAF and BRAF amplification coexist in 7%-11% of patients.

BACKGROUND: The management of melanoma patients with metastatic melanoma in the sentinel nodes (SN) is evolving based on the results of trials questioning the impact of completion lymph node dissection (CLND) and demonstrating the efficacy of new adjuvant treatments. In this landscape, new prognostic tools for fine risk stratification are eagerly sought to optimize the therapeutic path of these patients. METHODS: A retrospective cohort of 2,086 patients treated with CLND after a positive SN biopsy in thirteen Italian Melanoma Centers was reviewed. Overall survival (OS) was the outcome of interest; included independent variables were the following: age, gender, primary melanoma site, Breslow thickness, ulceration, sentinel node tumor burden (SNTB), number of positive SN, non-sentinel lymph nodes (NSN) status. Univariate and multivariate survival analyses were performed using the Cox proportional hazard regression model. RESULTS: The 3-year, 5-year and 10-year OS rates were 79%, 70% and 54%, respectively. At univariate analysis, all variables, except for primary melanoma body site, were found to be statistically significant prognostic factors. Multivariate Cox regression analysis indicated that older age (P < 0.0001), male gender (P = 0.04), increasing Breslow thickness (P < 0.0001), presence of ulceration (P = 0.004), SNTB size (P < 0.0001) and metastatic NSN (P < 0.0001) were independent negative predictors of OS. CONCLUSION: The above results were utilized to build a nomogram in order to ease the practical implementation of our prognostic model, which might improve treatment personalization.

Adalimumab is the only biological drug approved to date for the treatment of moderate and/or severe hidradenitis suppurativa. Adverse events reported during therapy include paradoxical psoriasiform reactions. No guidelines are currently available for the management of this clinical condition. The aim of this paper is to describe the incidence and clinical features of paradoxical psoriasiform eruptions occurring during treatment with adalimumab in patients with hidradenitis suppurativa and to report real-life experience in management and the possible role of other biologic agents for the treatment of both conditions.

Dupilumab is the first biological agent approved for treatment of moderate-to-severe atopic dermatitis (AD). Evidence of Dupilumab effectiveness on psychological outcomes beyond 16 weeks of treatment from real-life settings is lacking. To evaluate the effectiveness of Dupilumab treatment up to 32 weeks, focusing health-related quality of life and psychological outcome of patients with moderate-to-severe AD. An observational prospective cohort study was conducted in a real-life setting at an Italian tertiary centre. Assessment of outcome measures was carried out at baseline, after 16 and 32 weeks of treatment. A total of 171 patients were included. EASI-75 and EASI-90 were achieved in 85% and 60% of the participants, respectively, after 16 weeks, and in 89.6% and 69.8% after 32 weeks of treatment. Significant improvements (p < 0.001; r = 0.57-0.95) were found after 16 weeks for each outcome considered, including clinician and patient-reported measures of AD severity and scales of health-related quality of life and psychological morbidity, and maintained up to 32 weeks. Further analysis revealed that patients' quality of life was more associated with the subjective perception of disease severity rather than objective measures and suggested a possible different response to treatment based on the age of AD onset. Dupilumab was confirmed to be rapid, effective and safe in patients with moderate-to-severe AD. Its positive impact on psychological outcomes up to 32 weeks was ascertained here, adding new evidence on the need to consider subjective factors affecting patients' perception of disease severity in evaluating the response to treatment.
