Special Issue Information

Dear Colleagues,

The skin is a site commonly involved in pathological immune responses that can take place in the epidermal and/or dermal compartments. These immunopathological reactions often occur towards self-antigens and may be due to T cell-dependent and/or autoantibody-dependent mechanisms. In many inflammatory diseases, signals of the innate immune system typically initiate skin immune responses, while cells and cytokines of the adaptive immune system perpetuate the inflammation. An extensive crosstalk between the different cell types of the immune system, tissue cells, and pathogens is responsible for the complexity of skin immune reactions.

The recent increase in the understanding of immune-mediated and allergic skin disease pathogenesis has been enormous, leading to the development and introduction of new targeted therapeutic regimens. Moreover, identifying both clinical phenotypes and possible trajectories of treatment outcome has allowed for the most selective management to be applied to each patient. Hopefully, the near future will see a genetic and pathogenesis-driven treatment of those diseases.

This Special Issue aims to bring together the most relevant scientific research on immune-mediated and allergic skin diseases, focusing on clinical diagnosis, pathophysiology, and recent advancements in therapy.

HS patients frequently report typical neuropathic pain qualities, but its prevalence has been poorly described.

Background: Pain is a core symptom of hidradenitis suppurativa (HS) and is of complex, multifactorial origin. HS patients frequently report typical neuropathic pain qualities, but its prevalence has been poorly described. Methods: In this cross-sectional study, we examine the prevalence of neuropathic pain (NP) component and related pain-characteristics of a hospital-based cohort of patients with symptomatic HS. We administered the pain-DETECT tool (PDQ), a validated screening tool for NP, collecting clinical and patient-reported data on pain, pruritus and pain-management. We obtained 110 complete datasets from symptomatic HS patients (49.1% females; Hurley I (27.3%])–II (45.5%)–III (27.3%)). According to the PDQ tool, 30% of patients were classified with a high probability (>90%) of neuropathic pain (LNP). LNP status was significantly associated with increased pain severity, disease activity, pruritus intensity and use of pain medication. Regression analysis showed a significant impact of the PDQ score on patient-reported outcomes, including pain severity and the dimensions of activity and affective pain interference. HS patients may present a mixed chronic pain phenotype with a neuropathic component, thus requiring additional pain-assessments. A multi-modal approach to pain management, in combination with disease-specific treatment, should be implemented in future interventional studies. Full article

Background: The clinical features of adult-onset atopic dermatitis (AD) are heterogeneous and the diagnosis can be a challenge. A new biologic drug (dupilumab) has been approved for moderate to severe AD in adult patients. The efficacy and safety have been demonstrated in clinical trials, but these studies do not reflect conditions in daily practice and do not consider the different clinical manifestations of AD. Objectives: Analyzing the dupilumab activity in a real-world setting and comparing its efficacy on different AD phenotypes. Methods: We retrospectively evaluated 221 AD patients treated with dupilumab, stratified into six clinical phenotypes: classic, generalized eczema inflammatory and lichenoid patterns, prurigo, nummular eczema, and erythroderma. At baseline and at weeks 4, 16, and 52, the disease severity was assessed through the Eczema Area and Severity Index (EASI) and the quality of life was assessed through the Dermatology Life Quality Index (DLQI) questionnaire, Peak Pruritus Numerical Rating Scale (itch NRS), and Peak Sleep NRS. Results: We found a significant improvement after 16 weeks of treatment (p < 0.0001) in all six phenotypes for all the assessed scores mentioned above, persisting up to week 52. The best improvement was seen in the more severe phenotypes, particularly the erythrodermic one. Conclusions: The present study confirmed the efficacy and safety of dupilumab in the treatment of severe AD. Its strength was in the stratification of AD patients in six different phenotypes based on their clinical presentation, all of whom markedly improved in terms of both clinically evident and reported symptoms, as well as their quality of life.

Dupilumab is an anti-interleukin-4 receptor monoclonal antibody that was recently approved for the treatment of atopic dermatitis (AD). In this single-center retrospective study, clinical baseline data of 117 severe AD patients treated with dupilumab were collected. At baseline and at weeks 4 and 16, disease severity was assessed through the Eczema Area and Severity Index (EASI) and quality of life through the Dermatology Life Quality Index (DLQI) questionnaire, Patient-Oriented Eczema Measure (POEM), Hospital Anxiety and Depression Scale (HADS), Peak Pruritus Numerical Rating Scale (NRS-itch), and VAS-sleep. Response to dupilumab was defined as an improvement of ≥75% in EASI from baseline (EASI75). At multivariate analysis, AD onset before 18 years [OR, 2.9; 95% CI, 1.2–7.2; p = 0.0207] and absence of hypereosinophilia [OR, 2.24; 95% CI, 1.03–4.86; p = 0.0412] were identified as significant predictive parameters for response to dupilumab in terms of EASI75 at week 4 but not at week 16. Significant reductions in EASI, DLQI, POEM, HADS, NRS-itch, and VAS-sleep were found between week 4 versus baseline (p < 0.0001 for all) and week 16 versus baseline (p < 0.0001 for all). Early AD onset and absence of hypereosinophilia may be suggested as predictive markers of early response to dupilumab. We confirmed the efficacy and safety of this agent along with the improvement of life quality in severe AD patients. Full article
