Little information is available from real-life studies evaluating the efficacy of guselkumab in moderate-to-severe psoriasis. In this real-life study, we retrospectively examined a database of 52 patients with moderate-to-severe psoriasis treated with guselkumab (100 mg, s.c.) and followed for 1 year. Disease severity and treatment response was assessed by the Psoriasis Area and Severity Index (PASI) at baseline and after 4, 12, 20, 28, 36, 44, and 52 weeks. Predictors of a PASI response were evaluated by univariate and multivariate regression. After 12 months, 84.2% of patients (mean age 51.3 ± 14.1 years) treated with guselkumab achieved a PASI score of <3. Furthermore, PASI score decreased from 20 ± 13.3 at baseline to 4.4 ± 4.7 and 2.7 ± 3.9 at 12 and 20 weeks, and PASI 75, 90, and 100 response was achieved in 84.2%, 78.9%, and 63.2% of patients respectively at 12 months. Stepwise multivariate regression analysis revealed that previous biological treatment and the presence of comorbidities were associated with poorer response between 28–44 weeks, however the presence of obesity per se was not associated with poorer response. Difficult-to-treat areas were also improved as early as 12 weeks following guselkumab. Guselkumab was observed to be effective and safe in patients with moderate-severe chronic psoriasis in a real world-setting.

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that was interrupted in only 9.9% (156/1576) of cases, while systemic immunosuppressive compounds were more frequently withdrawn.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.

Background: There is limited long-term, real-world evidence on the efficacy and safety in patients with plaque psoriasis treated with secukinumab. We present results at 136 weeks in a real-world setting with focus on special populations. Research design and methods: Retrospective analysis of 151 patients with chronic plaque psoriasis who initiated treatment with secukinumab between September 2015 and May 2019. Secukinumab 300 mg was administered once weekly for 5 weeks followed by once monthly. Main outcome measures: Clinical and laboratory assessments were performed up to 136 weeks. Results: At 16 weeks, 90%, 79%, and 63% of patients achieved Psoriasis Area and Severity Index (PASI) 75, PASI 90, and PASI 100, respectively, compared with 79%, 72%, and 55% of patients after 136 weeks of therapy with secukinumab. Fifteen of the 151 patients experienced an adverse event, the most common of which was candida infection (4%). Biological treatment naïve was significantly associated with response to therapy at 1 and 2 years (P < 0.0001). There were no safety issues in patients with infection with HBV, HCV or mycobacterium tuberculosis. Conclusions: Our results confirm the rapidity of action of secukinumab as well as its long-lasting efficacy and good safety in real-world clinical practice.

Atopic dermatitis (AD) is a dermatological disorder that affects patients’ mental health and psychological state in complex ways. The importance of understanding the entire scope of this burden is well recognized, but there is limited comprehensive information about the resulting stress on adult patients with AD. This study aimed to determine the degree of psychological stress in patients with AD compared to healthy participants. A total of 352 adult patients participated in this cross-sectional study—174 with AD and 178 healthy participants. Demographic and clinical data were collected. Itch and sleep disturbance were assessed using a numeric rating scale and a visual analogue scale. The 20-item Toronto Alexithymia Scale (TAS-20) and Beck Depression Inventory (BDI) questionnaires were administered to assess the symptoms of alexithymia and depression. Quality of life (QOL) was assessed in AD patients using the Dermatology Quality Index. In our study, we found high TAS-20 and BDI scores among patients with AD. The prevalence of alexithymic personality features was 56.3% in patients with AD versus 21.3% in healthy controls (p < 0.001). Based on BDI scoring (BDI-21 > 13), depression was suspected in a significantly higher number of patients with AD than in the control group (56.9% (99/174) vs. 15.7% (28/178); p < 0.0001). Eczema Area and Severity Index (EASI) score did not show any significant correlations with psychological parameters. Among clinical parameters, only sleep disturbance was positively correlated with depression (R = 0.307, p < 0.005). Our data show that the severity index score as a representative factor of skin involvement has a limited role in predicting the effect of skin diseases on mental status. Screening and assessment for psychiatric disorders, QOL, and sleep disturbance in patients with atopic dermatitis cannot be neglected by physicians and they should be treated in clinical practice with the consideration of psychosomatic approaches.
