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.

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.

Psoriasis is a multi-systemic chronic inflammatory disease that affects about 1.5-3% of the general population, of which almost 20% suffer from a moderate-severe form. Those patients can be treated with a systemic agent and in case of scarce response or contraindications, they may require a biologic therapy, such as tumor necrosis factor or interleukin-12/23 inhibitors. When also these agents fail, clinicians face a true therapeutic challenge. We report a case series of multi-failure 16 patients, successfully treated with secukinumab, a human monoclonal antibody that selectively neutralizes interleukin-17 A and is recently approved for the treatment of plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis.
