Therapeutic Potential of IL-1 Antagonism in Hidradenitis Suppurativa

The immunopathogenesis of HS is partially understood and exhibits features of an autoinflammatory disease; it is associated with the potential involvement of B cells and the contribution of Th1 or Th17 cell subsets. Recently, the pathogenic role of both innate immunity and IL-1 family cytokines in HS has been deeply investigated. Several agents targeting the IL-1 family pathway at different levels are currently available and under investigation for the treatment of HS. HS is still characterized by unmet clinical needs and represents an expanding field in the current scientific research. The aim of this narrative review is to describe the pathological dysregulation of IL-1 family members in HS and to provide an update on therapeutic strategies targeting IL-1 family cytokine signaling. Further clinical and preclinical data may likely lead to the enrichment of the therapeutic armamentarium of HS with IL-1 family cytokine antagonists.

Association between maternal dupilumab exposure and pregnancy outcomes in patients with moderate-to-severe atopic dermatitis: A nationwide retrospective cohort study

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.

Low grade of satisfaction related to the use of current systemic therapies among pustular psoriasis patients: a therapeutic unmet need to be fulfilled

Introduction

Pustular psoriasis is considered a separate entity from plaque psoriasis and can be categorized as generalized pustular psoriasis (GPP), acrodermatitis continua of Hallopeau, or palmoplantar pustulosis (PPP). Current guidelines mostly include treatment options that have not been specifically developed for the treatment of pustular psoriasis. The majority of them does not have indication for the treatment of pustular psoriasis. Their effectiveness and safeness have been described in small cohort-based studies or case series with a low level of evidence. Previous studies evaluated treatment response through physician-based assessment but none reported patient satisfaction to treatment, quality of life and patient perception of disease severity during systemic therapies, particularly with biologics commonly used in plaque psoriasis. This study aimed to investigate patient satisfaction to treatment and patients' quality of life during treatment, correlating patient-reported outcomes with residual disease severity.

Methods

A cross-sectional, cohort-based, single center study included patients affected by pustular psoriasis undergoing treatment with systemic agents. Demographic, clinical characteristics were collected. Treatment satisfaction as well as disease severity were assessed through dedicated assessment scores.

Results

A total of 31 patients affected by GPP or PPP were included. Despite biologic treatment, 80.6% of patients continued to experience mild-to-severe disease activity, with discrepancies between patient and physician assessments. Patients reported a substantial impairment in their quality of life, with notable limitations in physical activity and emotional distress. Mental health conditions, such as depression and anxiety disorders, were common. Treatment satisfaction varied, with moderate scores for effectiveness and convenience. Only a small proportion of patients (41.9%) reported complete or high overall treatment satisfaction. GPP and PPP subcohorts exhibited similar quality of life and treatment satisfaction levels.

Discussion

This study highlights the suboptimal control of PP despite biologic therapies, resulting in a significant impact on patients' quality of life and treatment satisfaction. The findings highlight the need for specific therapies and standardized guidelines for managing PP. New targeted therapies, such as spesolimab, hold promise for optimizing treatment satisfaction and improving patients' quality of life in this challenging condition. Future research should focus on refining treatment strategies to address the unmet needs of PP patients comprehensively.

Analysis of predictive factors influencing dupilumab continuation rate in adult patients with atopic dermatitis: results from an Italian multicenter study

OBJECTIVES

The purpose of this study was to analyze the drug survival rate of dupilumab up to 2 years in a large real-world cohort of adult patients affected by moderate/severe atopic dermatitis (AD), and to investigate the clinical, demographic and predictive factors influencing the patients' treatment persistence.

MATERIAL AND METHODS

This study included adult patients affected by moderate-to-severe AD treated with dupilumab for at least 16 weeks who visited 7 dermatologic outpatient clinics in Lazio, Italy, from January 2019 until August 2021.

RESULTS

A total of 659 adult patients (345 male [52.3%], mean age: 42.8 years) with an average treatment duration of 23.3 months were enrolled in the study. Overall, 88.6% and 76.1% of patients were still on treatment after 12 and 24 months, respectively. The drug survival rate for discontinuation due to AEs and dupilumab ineffectiveness was 95.0% at 12 months and 90.0% at 24 months. The main reasons for drug discontinuation included inefficacy (29.6%), failed compliance (17.4%), persistent efficacy (20.4%) and adverse events (7.8%). Adult AD onset (≥18 years) and EASI score severity measured at the last follow-up visit were the only factors significantly associated with lower drug survival.

CONCLUSION

This study revealed an increased cumulative probability of dupilumab survival at 2 years, reflected by a sustained effectiveness and a favorable safety profile of the drug.

Identification of clinical predictors for dupilumab dose spacing in adults with atopic dermatitis: a real-world study

BACKGROUND

Dupilumab is a monoclonal antibody against the IL-4/IL-13 receptor-subunit approved for the treatment of moderate-severe atopic dermatitis (AD). Some attempts to increase dose interval have been described in both trial and real-world settings.

OBJECTIVE

This study aimed to identify predictive clinical and demographic factors affecting patient selection for dose spacing or treatment withdrawal due to satisfactory response.

MATERIALS AND METHODS

This retrospective study included adult patients with moderate-to-severe AD treated with dupilumab for at least 16 weeks. Descriptive statistics were performed to analyze demographic and clinical variables. Logistic regression models were used to identify predictor variables.

RESULTS

A total of 818 adult patients with moderate-to-severe AD was included in the study and 12% (97/818) of them performed dose spacing to 3-4 weeks or treatment withdrawal (8%, 67/818). The presence of non-cutaneous atopic manifestations (OR = 1.59, 95%CI = 1.06-2.38, p = 0.024), prurigo nodularis phenotype (OR = 4.5, 95%CI = 1.87-10.9, p = 0.001) and the age at treatment initiation (OR = 1.82, 95%CI = 1.12-2.94, p = 0.015) were confirmed as the strongest predictors of dose spacing or treatment withdrawal while maintaining dupilumab effectiveness.

CONCLUSION

Our findings contribute to define the patient profile that could maintain the therapeutic response after dose spacing or treatment withdrawal.

Long-term Effectiveness and Safety of Upadacitinib for Atopic Dermatitis in a Real-world Setting: An Interim Analysis Through 48 Weeks of Observation

BACKGROUND

Janus kinase (JAK) inhibitors, including upadacitinib, have been recently approved for the treatment of moderate-severe atopic dermatitis (AD) and real-world data on upadacitinib effectiveness and safety are limited. This interim analysis aimed to assess effectiveness and safety of upadacitinib throughout 48 weeks of observation in a real-world adult AD population.

METHODS

This prospective study collected data on adult patients affected by moderate-to-severe AD and treated with upadacitinib at the dosage of either 15 mg or 30 mg daily based on the physician decision. Upadacitinib was prescribed in the context of a national compassionate use programme. In this interim analysis, within patient comparisons of continuous scores of different scales (namely Eczema Area and Severity Index [EASI], body surface area [BSA], Dermatology Life Quality Index [DLQI], Patient Oriented Eczema Measure [POEM], Numeric Rating Scale [NRS] subtests) were performed. The percentage of patients achieving EASI 75, EASI 90 and EASI 100 at Week 16, 32 and 48 was also evaluated.

RESULTS

One hundred and forty-six patients were included in the analysis. Upadacitinib 15 mg or 30 mg daily was prescribed as monotherapy in most cases (127/146, 87.0%). Upadacitinib was initially prescribed at the dosage of 30 mg daily in 118 of 146 (80.8%) patients and 15 mg daily in 28/146 (19.2%) patients. A significant improvement in the clinical signs and symptoms of AD was detected by Week 16 and throughout the study period. EASI 75, EASI 90 and EASI 100 responses were achieved by 87.6%, 69.1% and 44.3% at Week 48, associated with a sustained reduction in the mean values of all physician-reported (EASI and BSA) and patient-reported (Itch- Sleep- and Pain-NRS, DLQI, and POEM) disease severity outcomes, up to 48 weeks of treatment. Treatment response observed in 15 mg upadacitinib-treated patients was comparable with that detected in 30 mg upadacitinib-treated patients, revealing no statistical difference between the two patient sub-cohorts. Through the observation period, dose reduction or escalation was observed in 38/146 (26%) of treated cases. Overall, 26 of 146 (17.8%) patients experienced at least one adverse event (AE) during the treatment period. In total, 29 AEs were recorded and most of them were evaluated as mild to moderate, while in 4 cases the occurrence of AE led to drug discontinuation, for a total of 7/146 (4.8%) dropouts.

CONCLUSION

This study provides strong evidence of a sustained response obtained by upadacitinib in AD patients, who had failed to respond to conventional or biological systemic agents, through 48 weeks of observation. Upadacitinib was also demonstrated to be advantageous in terms of flexibility in dose reduction or escalation as upadacitinib dose was shaped on clinical needs that, in a real-world setting, might frequently change.

Dupilumab-associated ocular adverse events are predicted by low tear break-up time and correlate with high IL-33 tear concentrations in patients with atopic dermatitis

Dupilumab, blocking IL-4 and IL-13 signals, improves atopic dermatitis and Quality of Life but might be also associated with the occurrence of ocular adverse events (OAEs). The main objective of our prospective study was to characterize the cytokine and chemokine profile in the tear fluid of dupilumab-treated patients with moderate-to- severe atopic dermatitis and to identify biomarkers predicting the occurrence of ocular adverse events. Patients with moderate-to-severe AD underwent dermatological and ophthalmological evaluation at the baseline (T0) and week 16 or at the time of an eventual ocular adverse events (T1). A multiplex immunoassay measuring multiple cytokines and chemokines in the tear fluid extracted during ocular examination at both T0 and T1 was performed. Thirty-nine patients with moderate-to-severe AD and treated with dupilumab were included in the study. Baseline tear fluid levels revealed a significantly higher concentration of type 2 cytokines and chemokines in AD patients than healthy controls. The occurrence of ocular adverse events during dupilumab therapy was associated with a significant increase of IL-33 tear fluid levels and a significantly lower tear break-up time, this latter also identified as predictive factor. Our findings suggest that the ophthalmological examination should be considered a valid support to identify patients at risk of developing OAEs and to provide their appropriate management.

Current treatment goals are achieved by the majority of patients with atopic dermatitis treated with tralokinumab: results from a multicentric, multinational, retrospective, cohort study

BACKGROUND

Tralokinumab is a human monoclonal antibody targeting interleukin-13 that is approved for the treatment of moderate-severe atopic dermatitis. Studies analyzing the efficacy and safety of tralokinumab in a real-world setting are scarce.

RESEARCH DESIGN AND METHODS

A European, multicentric, real-world, retrospective cohort study was defined to assess the effectiveness and safeness profile of tralokinumab, investigating the achievement of pre-specified treatment goals; and to detect potential differences in terms of effectiveness and safeness across some selected patient subcohorts.

RESULTS

A total of 194 adult patients were included in this study. A significant improvement in physician-assessed disease severity was detected at each follow-up visit as compared with baseline and similar trend was observed for patient-reported outcomes and quality of life. No meaningful difference in effectiveness was found when considering patient age (<65 versus ≥65 years), neither dissecting patient cohort in dupilumab-naive vs dupilumab-treated subjects. Among tralokinumab-treated patients, 88% achieved at least one currently identified real-world therapeutic goal at week 16.

CONCLUSIONS

This retrospective multicenter study confirmed the effectiveness and safeness of tralokinumab throughout 32 weeks of observation, showing the achievement of therapeutic goals identified in both trial and real-world settings in a large proportion of tralokinumab-treated patients.

National Information Campaign Revealed Disease Characteristic and Burden in Adult Patients Suffering from Atopic Dermatitis

Atopic dermatitis (AD) is a common inflammatory skin disease often associated with a significant impairment in the quality of life of affected patients. The Italian Society of Dermatology and Venereology (SIDeMaST) planned a national information campaign, providing direct access to 27 dermatologic centers dedicated to the management of AD. The aim of this study aimed was to outline critical aspects related to AD in the general population. Overall, 643 adult subjects were included in this study, and in 44.2% (284/643) of cases, a diagnosis of AD was confirmed, whereas about 55% of subjects were affected by other pruritic cutaneous diseases. Higher intensity of pruritus and sleep disturbance, as well as an increased interference in sport, work, and social confidence was reported in the AD group compared to the non-AD group. In the AD subgroup, the mean duration of disease was of 15.3 years, with a mean eczema area and severity index (EASI) score of 11.2, and investigator global assessment (IGA) score of 1.9 and an itch numeric rating scale (NRS) of 6.9. Almost 32% of patients were untreated, either with topical or systemic agents, whereas 44.3% used routine topical compounds (topical corticosteroids and calcineurin inhibitors), and only 7.0% of patients were systemically treated. Only 2.8% of patients reported complete satisfaction with the treatment received for AD to date. This study reveals a profound unmet need in AD, showing a poorly managed and undertreated patient population despite a high reported burden of disease. This suggests the usefulness of information campaigns with the goal of improving patient awareness regarding AD and facilitating early diagnosis and access to dedicated healthcare institutions.

Effectiveness and Safety of Upadacitinib in the Treatment of Moderate-Severe Atopic Dermatitis: A Multicentric, Prospective, Real-World, Cohort Study

Background

The efficacy and safety of upadacitinib in atopic dermatitis (AD) have been defined in clinical trials, but no real-world data are currently available. We aimed to assess the safety and effectiveness of upadacitinib in a real-world AD patient cohort that mostly included patients who failed the available systemic therapies, including dupilumab.

Methods

Prospective cohort study collecting data on upadacitinib-treated AD adult patients completing at least 16 weeks of therapy.

Results

Forty-three patients showed rapid and marked response to upadacitinib with significant reduction of all disease severity scores since the first follow-up visit. At week 16, Eczema Area and Severity Index (EASI) 75, EASI 90, and EASI 100 response was observed in 97.5%, 82.1%, and 69.2% of patients, respectively. EASI 90 response reflected the achievement of a clear or almost clear condition (POEM 0-2), self-evaluated by 79.5% of patients. Patients’ quality of life improved as suggested by the achievement of DLQI 0/1 by 38.5% of patients at week 4, and by 76.9% at week 16.

Conclusion

Elevated effectiveness and favorable safety of upadacitinib were confirmed in patients unresponsive to dupilumab, who were not included in upadacitinib trials.

Head Injury Assessment in Italian rugby union: a two-seasons prospective analysis

BACKGROUND

In Italy, to the best of our knowledge, there is no literature relating to injury and concussion epidemiology in rugby union. Therefore, the primary aim of this study is to describe the incidence of sport-related concussion in Italian rugby union and the associated management of Head Injury Assessment (HIA).

METHODS

This is an observational prospective study, analysing the Italian elite rugby championship (Top 12 and Coppa Italia) for two seasons (2018/2019 and 2019/2020). Twelve male teams of the Italian elite rugby championship were included. The diagnosis of traumatic brain injury was provided by a team doctor with HIA, while no match day doctor or video analysis was available. A concussion expert of Italian Rugby Federation reviewed all the HIAs. The outcome of interest were: incidence, playing situation and mechanism responsible for traumatic brain injury.

RESULTS

In the study period, 47 HIAs were performed during matches (45.3/1000 player-match-hours) and 7 concussions were diagnosed by team doctors (6.75/1000 player-match-hours). After the concussion expert HIAs' review, the thirty-three percent of 16 diagnoses were made later, during follow-up, or based on clinical suspicion. Most symptoms complained about by players were neck pain and headache, in 14.6% and 13.4% of HIA, respectively. Concussions were predominately the result of tackling (46.5%) for the tackler (90.9%).

CONCLUSIONS

The incidence of concussion in Italian Rugby appears to be low compared to that of rugby outside Italy, which is likely due to the learning curve of HIA and the absence of video analysis and match day doctors during competitions. The implementation of educational projects may be fundamental to promoting HIA process.

Biological agents targeting interleukin-13 for atopic dermatitis

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin disease that is pathogenically driven by type-2 inflammation. Interleukin-13 (IL-13) plays a central role in AD pathogenesis, as confirmed by the clinical efficacy of agents that selectively block IL-13, although their therapeutic value and place-in-therapy are incompletely defined.

AREAS COVERED

The aim of this review article is to describe preclinical and clinical data regarding selective IL-13 inhibitors investigated in AD. In particular, we discuss the clinical outcomes obtained with lebrikizumab and tralokinumab, which are in a more advanced phase of development.

EXPERT OPINION

Biological agents that neutralize IL-13 have demonstrated clinical benefits in treating AD with excellent safety profiles. Robust clinical evidence exists in support of tralokinumab, which underwent phase III trials, met the predefined primary endpoints, and is approaching the market. In contrast, clinical trial testing for lebrikizumab needs to be completed to fully assess its therapeutic potential.

PLAIN LANGUAGE SUMMARY

Atopic dermatitis (AD) is a chronic pathological inflammatory skin disease that results from type-2 inflammation. Selective interleukin-13 (IL-13) inhibitors have shown clinical efficacy against AD, suggesting that IL-13 plays a central in AD pathogenesis. However, the therapeutic value and place-in-therapy of IL-13 inhibitors are incompletely defined. The aim of this review article is to describe preclinical and clinical data for selective IL-13 inhibitors against AD, including lebrikizumab and tralokinumab, which are in a more advanced phase of development. The up-to-date overview of the strengths and limitations of different agents used to treat AD discussed in this article might be useful in driving treatment decision.

Therapeutic Impact and Management of Persistent Head and Neck Atopic Dermatitis in Dupilumab-Treated Patients

BACKGROUND

Localization of atopic dermatitis (AD) in exposed areas such as the hands, head, and neck has been considered as a negative factor impacting on dupilumab response, although a comparison of exposed versus unexposed areas is not currently available.

OBJECTIVES

The aim of this study is to evaluate the clinical response to dupilumab depending on the presence or persistency of AD skin manifestations in specific body areas.

METHODS

The study retrospectively collected clinical and demographic data of adult patients affected by moderate to severe AD. Based on the anatomical sites involved, 5 subcohorts of patients were identified.

RESULTS

A total of 41 patients were included in the study. Disease amelioration was detected during the study period, although baseline head/neck and hand localization was associated with a significantly lower likelihood of achieving an Eczema Area Severity Index (EASI) ≤1. In addition, patients with head/neck persistency showed a significantly lower response when compared to patients without persistency of head/neck AD in terms of both mean EASI and Dermatology Life Quality Index (DLQI) reduction.

CONCLUSION

AD localization in exposed areas at the baseline and AD persistency at the head/neck may have a negative impact on certain treatment response parameters to dupilumab therapy.

Effectiveness and Safety of Long-Term Dupilumab Treatment in Elderly Patients with Atopic Dermatitis: A Multicenter Real-Life Observational Study

OBJECTIVE

The objective of this study was to assess the effectiveness and safety of dupilumab in treating elderly patients with atopic dermatitis from baseline to 52 weeks.

METHODS

A retrospective observational real-life study was conducted in a group of elderly patients with severe atopic dermatitis treated with dupilumab for 52 weeks. Inclusion criteria were: age ≥ 65 years; diagnosis of atopic dermatitis made by an expert dermatologist; Eczema Area and Severity Index ≥ 24; and a contraindication, side effects, or failure to respond to cyclosporine. The primary outcome was the mean percentage reduction in the Eczema Area and Severity Index score from baseline to week 52. Secondary measures included the mean percentage reduction in the Pruritus and Sleep Numerical Rating Scales and the Dermatology Life Quality Index, and the types and rates of adverse events from baseline to week 52.

RESULTS

One hundred and five patients were eligible for the study. Flexural dermatitis was the most frequent clinical phenotype (63.8%). The coexistence of more than one clinical phenotype was found in 70/105 (66.6%) patients. We observed a reduction in all disease severity scores from baseline to week 52 (p < 0.001). Adverse events were recorded in 30/105 (28.6%) patients, with conjunctivitis and injection-site reaction the most frequent.

CONCLUSIONS

In this study, dupilumab is an effective and safe treatment for the long-term management of atopic dermatitis in patients aged over 65 years.

Management of patients with atopic dermatitis undergoing systemic therapy during COVID-19 pandemic in Italy: Data from the DA-COVID-19 registry

Background

Few and small studies have described the management of immunomodulant/immunosuppressive therapies or phototherapy in atopic dermatitis (AD) patients during coronavirus disease 2019 (COVID‐19) pandemic.

Methods

A national registry, named DA‐COVID‐19 and involving 35 Italian dermatology units, was established in order to evaluate the impact of COVID‐19 pandemic on the management of adult AD patients treated with systemic immunomodulant/immunosuppressive medications or phototherapy. Demographic and clinical data were obtained at different timepoints by teledermatology during COVID‐19 pandemic, when regular visits were not allowed due to sanitary restrictions. Disease severity was assessed by both physician‐ and patient‐reported assessment scores evaluating itch intensity, sleep disturbances, and AD severity.

Results

A total of 1831 patients were included, with 1580/1831 (86.3%) continuing therapy during pandemic. Most patients were treated with dupilumab (86.1%, 1576/1831) that was interrupted in only 9.9% (156/1576) of cases, while systemic immunosuppressive compounds were more frequently withdrawn. Treatment interruption was due to decision of the patient, general practitioner, or dermatologist in 39.9% (114/286), 5.6% (16/286), and 30.1% (86/286) of cases, respectively. Fear of increased susceptibility to SARS‐CoV‐2 infection (24.8%, 71/286) was one of the main causes of interruption. Sixteen patients (0.9%) resulted positive to SARS‐CoV‐2 infection; 3 of them (0.2%) were hospitalized but no cases of COVID‐related death occurred.

Conclusions

Most AD patients continued systemic treatments during COVID pandemic and lockdown period, without high impact on disease control, particularly dupilumab‐treated patients.

Successful Combination of Systemic Agents for the Treatment of Atopic Dermatitis Resistant to Dupilumab Therapy

BACKGROUND

Dupilumab, a monoclonal antibody inhibiting the signaling pathway of IL-4/IL-13, was shown to be safe and effective in the treatment of moderate/severe atopic dermatitis (AD) in several clinical trials and real-life experiences, with only a small percentage of patients showing to be resistant or to lose disease control.

OBJECTIVES

In this study, we investigated the effectiveness and safety in combining dupilumab with systemic agents or phototherapy in patients experiencing an inadequate response to dupilumab.

METHODS

This retrospective, monocentric, observational study consecutively included patients aged >18 years, with moderate-severe AD, under treatment with dupilumab. In this cohort of patients, we analyzed data of subjects who experienced an inadequate response to dupilumab, even when combined with topical corticosteroids, and for whom an additional systemic treatment or phototherapy was combined to dupilumab.

RESULTS

In this study, we included a total population of 69 patients treated with dupilumab. In 12/69 patients (17.4%) showing an inadequate response to dupilumab, a combined treatment consisting of dupilumab plus methylprednisolone (n = 5), cyclosporine (n = 4), methotrexate (n = 2), or narrow band-UVB (n = 1) was administered. Overall, after 8 weeks of combined therapy, the majority of patients (11 of 12) obtained an improvement of signs and symptoms of AD. Patients treated with combined therapy did not experience any adverse events, neither did they withdraw treatment because of the occurrence of adverse events.

CONCLUSIONS

This study suggests that the combination of dupilumab with a conventional drug or phototherapy may represent a valid therapeutic choice, maintaining a good safety profile in AD patients recalcitrant to dupilumab monotherapy.

Leser-Trélat sign as a rare manifestation of cutaneous melanoma

Leser-Trélat Sign (LTS) is a rare paraneoplastic syndrome characterized by the sudden eruption of multiple seborrheic keratoses in patients with internal malignancy, commonly localized in the gastrointestinal tract. We report an 80-year-old female patient showing a rapid increase in the number and size of seborrheic keratosis associated with the diagnosis of a cutaneous nodular melanoma (Breslow thickness: 4.5 mm) located on the right flank. After the excision of melanoma, subsequent staging procedures resulted negative, moreover no evidence of melanoma recurrence and no changes of the seborrheic keratoses was detected after a follow-up of 52 months. Although the association between melanoma and Leser Trelat sign is rare, an accurate skin examination with the aid of dermatoscopy searching for undiagnosed skin cancers, should be suggested in patient with sudden eruption of keratosis seborrheic to early diagnose and treat a possible melanoma.

Disease Severity Is Associated with Alexithymia in Patients with Atopic Dermatitis

BACKGROUND

Atopic dermatitis (AD) is a chronic inflammatory skin disorder that is associated with higher rates of psychological disorders, but limited evidence supported the association with alexithymia, a psychoaffective dysfunction.

OBJECTIVES

This study was aimed to investigate the occurrence of alexithymia in AD patients, compared to healthy subjects.

METHODS

This cross-sectional study assessed AD severity by the Eczema Area and Severity Index (EASI) score, sleeplessness and itch by a numeric rating scale (NRS), and alexithymia by the 20-item Toronto Alexithymia Scale (TAS-20) score. The association between disease characteristics and alexithymia was evaluated through several logistic regression models.

RESULTS

202 AD patients and 240 healthy subjects were included in this study. The alexithymic personality trait (TAS-20 ≥51) was more frequently observed among AD patients compared to the control group (62.4% [126/202] vs. 29.2% [70/240], p < 0.0001). In particular, alexithymia (TAS-20 score ≥61) was detected in a significantly higher number of AD patients than in the controls (27.7% [56/202] vs. 7.5% [18/240]; p < 0.0001), whereas borderline alexithymia was detected in 34.6% (70/202) of AD patients compared to 21.7% of healthy controls. Alexithymia was more common among severe AD patients (43.6%) compared to mild AD patients (15.6%) and correlated with itch intensity and sleep disturbances. Among clinical variables, ordered logistic regression analyses revealed disease severity as predictor of alexithymia. Indeed, univariate analysis showed EASI score, sleep NRS, and itch NRS being significantly associated with alexithymia, while a multivariate model identified increased EASI score values as predicting factor.

CONCLUSION

This study described alexithymia in AD patients correlating its occurrence with clinical AD severity markers (EASI score, itch, and sleeplessness) and identifying the increase in EASI score as predicting factor.

A case of disseminated perforating necrobiosis lipoidica

Perforating necrobiosis lipoidica (PNL) is a granulomatous inflammatory skin disease that usually occurs in patients with diabetic. We present a case of a female patient affected by a disseminated form of necrobiosis lipoidica.
