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.
Topical rapamycin can be considered a safe option for the treatment and the prevention of facial angiofibromas in younger patients, but the best formulation has not been established. Our review demonstrates that ointment and gel should be preferred, but it is not clear which concentration is optimal. Long-term and comparative studies between topical rapamycin and ablative techniques are required to establish which treatment has a better outcome and lower recurrence rate.
Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disorder that has been reported to be associated with malignancies. Some authors described several cases of pemphigoid associated with malignancies (PAM); however, the evidence of this correlation still remains controversial. Several theories have been postulated to explain the relationship between malignant neoplasms and BP; the main theory suggests that antibodies directed against tumor-specific antigens of malignant cells may cross-react with antigens (like BP antigens) in the basement membrane zone leading to the formation of blisters. We performed an extensive review of the English published work focusing on the epidemiology, the pathogenetic theories and the clinical and histological aspects of the disease. We identified 40 cases of PAM: of these, seven cases were associated with hematological malignancies and 33 with solid tumors. Physicians should be aware of the existence of PAM and we suggest an oncological screening in early-onset pemphigoid, in patients with a former oncological history, in those with signs and symptoms that could be related to a neoplasm and in BP refractory to common immunosuppressive therapy.

In Milan, Italy, after the end of the lockdown period (March and April 2020), we observed several patients with seborrheic dermatitis (SD) who showed a more or less important worsening of their disease. All patients used anti‐coronavirus‐19 (COVID‐19) face mask for many hours per day. According to the clinical point of view, the worsening was characterized by increased erythema and desquamation as well as itching worsened. In the last few weeks, some articles have been published on cases of dermatitis of the face associated with the use of anti‐COVID‐19 masks. Some authors hypothesized that this condition is due to high temperature of the face covered by the mask, that induces an increased sebum excretion rate. In our patients with SD, it is possible that high temperature of the face induces abnormalities of microbiota (proliferation of
Malassezia
spp.?) and permeability of skin barrier, and increases sweating with irritant action and worsening of itching.
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 animprovement 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
