Background: Many national guidelines at the European level recommend first‐line therapy based on the anti‐TNF‐alpha adalimumab for treatment of psoriasis and psoriatic arthritis, mainly for economic reasons. Consequently, patients being treated with newer IL‐17 and IL‐23 inhibitors underwent previous unsuccessful first‐line adalimumab‐based therapy. Objectives: Evaluate the efficacy and safety of IL‐17 and IL‐23 inhibitors after treatment with adalimumab compared to adalimumab‐naive psoriatic patients. Methods: We retrospectively analysed 1053 psoriatic patients treated with anti‐IL17 and anti‐IL23 agents, which included 68 and 24 adalimumab‐experienced and 399 and 260 bio‐naive patients. Efficacy was assessed with mean PASI, PASI90, PASI100, and <3. Results: Concerning the achieving of PASI100, PASI90 and PASI < 3 in patients treated with anti‐IL17 agents, no significant differences were observed between adalimumab‐experienced and bio‐naive patients. In patients treated with an anti‐IL‐23 agent, a faster response was observed in bio‐naive patients, with PASI < 3 significantly higher than ADA‐experienced patients at 16 weeks (77% vs. 58% p = 0.048). In a sub‐analysis that evaluated the performance of anti‐IL17 and anti‐IL23 agents in adalimumab‐experienced patients with a history of secondary failure, no significant differences were found. In multivariate analysis of PASI100, only anti‐IL‐17 therapy appeared to have a negative impact at 52 weeks (OR: 0.54 p = 0.04) independently of previous treatment. For PASI90, type of treatment and bio‐naïve status did not seem to have an impact at any time point. Conclusions: Anti‐IL 23 and anti‐IL 17 agents are not significantly different in terms of efficacy in bio‐naive patients or as second‐line therapy after failure with a biosimilar or originator adalimumab.

Ixekizumab showed significantly higher efficacy in terms of PASI 90 at week 24, and a higher superiority of PASI 90 and PASI 100 also at week 48. In bio-naive patients, we found a significantly higher rate of PASI-90, PASI < 3 and PASI-100 with ixekizumab compared to the secukinumab ( I P i < 0.05), while in bio-experienced patients no significant difference was observed. There was no difference between the two drug survival curves among the two treatment arms. gl PASI-90 and PASI-100 response rates were achieved at week 12 by 124 (48%) and 108 (42%) in the secukinumab group ( I P i = 0.001), while 118 (64%) and 100 (54%) in the ixekizumab group ( I P i = 0.014) respectively (Figure 1b).

Background: Inverse psoriasis (IP) is a variant of plaque psoriasis involving flexor surfaces. A clear definition of IP is still lacking. Therapy is based on topical and systemic treatments, including classic systemic drugs and biologic agents, but a well-defined therapeutic strategy is absent., Materials and Methods: This retrospective study investigated the general characteristics of patients with IP or vulgar psoriasis and compared the effectiveness of anti-interleukin-17 or anti-interleukin-23 agents in the same groups. Second, treatment effectiveness and the demographic characteristics of IP patients treated with IL-23 and IL-17 inhibitors were also compared. IP patients were included if they had specific psoriatic involvement of the axillary, inguinal, or submammary lines, breast folds, antecubital and popliteal pits, intergluteal fold, and perianal area. Patients with vulgar plaque psoriasis and concomitant intertriginous involvement were included in the vulgar psoriasis cohort., Results: Patients with IP were prevalently female and treated with IL-17 inhibitors compared to those with vulgar psoriasis. They also had a greater risk of drug discontinuation and subsequent therapeutical switch (32.1% vs. 18.1%, P = 0.002). At later time points, those with IP showed progressively slower achievement of PASI100 and 90 compared to the cohort with vulgar psoriasis. In the IP cohort, there was greater joint involvement in patients treated with an anti-IL-17 agent (P = 0.011), who also had a lower median age of onset (P = 0.011) compared to patients treated with an anti-IL-23 agent. Patients with IP treated with an anti-IL-23 agent initiated with a lower mean PASI and showed a slower response than patients on an anti-IL-17 agent. At later time points, progressively greater effectiveness of IL-23 inhibitors was observed compared to IL-17 inhibitors., Conclusions: Patients with IP responded less to biologic agents than those with vulgar psoriasis. In the IP cohort, IL-17 inhibitors had a faster onset than IL-23 inhibitors, but long-term anti-IL-23 agents seem to be associated with better outcomes., (© 2024 the International Society of Dermatology.)

Introduction: the selective IL-17 inhibitor secukinumab has demonstrated efficacy and safety in the treatment of moderate-severe psoriasis in recent years., Objective: evaluate effectiveness and drug survival (DS) of secukinumab in patients with psoriasis for up to 5 years., Methods: This is a retrospective study on a monocentric cohort of patients with psoriasis on secukinumab evaluating the achievement of PASI100, PASI90, and PASI ≤ 3 and DS analysis up to 260 weeks. DS multivariate analysis was carried out considering sex, age, age of onset of the disease, obesity, cardiovascular comorbidities, diabetes, involvement of difficult-to-treat sites, psoriatic arthritis, treatment-naïve status, and mean baseline PASI., Results: At baseline, we evaluated 255 patients on secukinumab. PASI100 was reached by 41.7% and 70.6% of patients at weeks 16 and 260, respectively. PASI90 showed a similar trend with 46.5% of patients achieving it at week 16 and 88.2% at week 260. Non-obese patients showed a faster response than patients with obesity in achieving PASI100, PASI90, and PASI ≤ 3, with significant differences at 28 weeks [55% vs. 40% ( p = 0.033), 64% vs. 49% ( p = 0.038), and 76% vs. 62% ( p = 0.036), respectively]. The estimated DS for secukinumab was 84.3% at 12 and 48% at 60 months. Obesity and smoking habits were associated with a higher risk of discontinuation in multivariate models (HR 1.6 CI 1.05-2.45, p = 0.028; HR 1.48 CI 1.01-2.17, p = 0.043, respectively)., Conclusions: Secukinumab showed effectiveness for up to 5 years of treatment, with a high DS and achievement of PASI100, PASI90, and PASI < 3 at these time points. Only obesity reduced the response and maintenance of DS.

Background: Biologics targeting IL-23 and IL-17 show efficacy and safety in the treatment of moderate-to-severe psoriasis., Objective: To investigate drug survival in patients with psoriasis treated with biologics., Patients and Methods: We performed a comparative evaluation of the achievement of PASI 90 and PASI ≤ 3 at 16, 28, and 52 weeks along with a DS (drug survival) analysis with IL-17 and IL-23 inhibitors brodalumab, ixekizumab, secukinumab, risankizumab, tildrakizumab, and guselkumab on 1,057 patients., Results: IL-17 inhibitors showed a faster achievement of PASI 90 and PASI ≤ 3 with significant superiority over IL-23 inhibitors at week 16 (p < 0.001; 56% vs. 42% and 70% vs. 59%, respectively). A difference was shown in favor of IL-23 inhibitors regarding DS (p < 0.001), which was 88% at 24 months vs. 75% for IL-17 inhibitors. In multivariate analysis, IL-23 inhibitors (HR 0.54 CI 0.37-0.78, p = 0.001), and male sex (HR 0.57 CI 0.42-0.76, p < 0.001) were all associated with a lower probability of drug interruption. Risankizumab (HR 0.42 CI 0.26-0.69, p = 0.001), guselkumab (HR 0.49 CI 0.24-0.99, p = 0.046), and male sex (HR 0.57 CI 0.43-0.77, p < 0.001) were associated with a lower probability of drug interruption than secukinumab., Conclusions: IL-23 inhibitors showed the best performance on DS. Overall, the most effective class was IL-17 inhibitors considering the short-term effectiveness, but long-term effectiveness is in favor of anti-IL-23., (© 2023 The Authors.

Available evidence to guide clinicians in the management of psoriasis patients with a history of malignancies is scarce. The latest generation of biological drugs is traditionally considered to be safe in patients with previous malignancy, although only case reports and short case series on the use of biological drugs in this population are available in the literature. In this paper, we present the experience of our clinic on 37 psoriatic patients with a previous diagnosis of neoplasia treated subsequently with biological drugs. Subsequently, a systematic review of the literature was performed and 38 cases were found. The main biologic used in our patients and the patients described in the literature was secukinumab. In both populations treatment with biologics was safe, disease progressions reported were not related to treatment. Based on our experience, which is the largest currently available, and the cases reported in the literature the treatment of psoriasis in patients with previously diagnosed cancer with biologics against TNFalpha, IL17, IL23, and IL12 would appear to be safe. The first experience on the use of Risankizumab and brodalumab on this special population is also reported in our series.

Background: Real-life studies in psoriasis are lacking. Many monoclonal antibodies targeting tumor-necrosis factor (TNF)-alpha, interleukin 17, and 23 are approved drugs for psoriasis treatment., Objectives: To compare the short and long-term efficacy, safety, and drug survival of anti TNF-alpha, anti-IL-17, and anti-IL-23 in a large case series., Methods: Psoriasis area severity index (PASI) and retention rates for adalimumab, secukinumab, guselkumab, ixekizumab, and brodalumab were analised., Results: A total of 263 patients were randomly selected among the five drugs register of the patients attending the Psoriasis Unit at the Turin University Hospital. The mean PASI at baseline was 14.3. Ixekizumab showed a significantly higher efficacy profile compared to other drugs in terms of PASI90 and PASI100 at week 12, 24, and week 48 even when adjusted for other confounding factors. This superiority was not followed by an expected higher drug survival. On the contrary, secukinumab was the only drug that showed a higher drug survival among bio-naïve patients.

Background: The current COVID-19 pandemic has influenced the modus operandi of all fields of medicine, significantly impacting patients with oncological diseases and multiple comorbidities. Thus, in recent months, the establishment of melanoma management during the emergency has become a major area of interest. In addition to original articles, case reports and specific guidelines for the period have been developed., Purpose: This article aims to evaluate whether melanoma management has been changed by the outbreak of COVID-19, and if so, what the consequences are. We summarized the main issues concerning the screening of suspicious lesions, the diagnosis of primary melanoma, and the management of early-stage and advanced melanomas during the pandemic. Additionally, we report on the experience of our dermatological clinic in northern Italy., Methods: We performed a literature review evaluating articles on melanomas and COVID-19 published in the last two years on PubMed, as well as considering publications by major healthcare organizations. Concerning oncological practice in our center, we collected data on surgical and therapeutic procedures in patients with a melanoma performed during the first months of the pandemic., Conclusions: During the emergency period, the evaluation of suspicious skin lesions was ensured as much as possible. However, the reduced level of access to medical care led to a documented delay in the diagnosis of new melanomas. When detected, the management of early-stage and advanced melanomas was fully guaranteed, whereas the follow-up visits of disease-free patients have been postponed or replaced with a teleconsultation when possible.

Anogenital warts (AGWs) are an important issue for public health centers dealing with Sexually Transmitted Infections. They are epidemiologically relevant, with significant morbidity and an established effective treatment is lacking. In this article, we examine the epidemiological, diagnostic, and therapeutic aspect of the problem in order to give an up to date picture of the situation and a practical clue for the management of AGWs.

Objective: To quantify earlier capillary diameter abnormalities, observed by nailfold videocapillaroscopy (NVC), in primary Raynaud phenomenon (PRP) subjects compared with RP subjects later evolved to systemic sclerosis (SSc)-associated secondary Raynaud phenomenon (SRP)., Methods: There were 6112 NVC images of 191 subjects analyzed at baseline and after a mean followup of 42.77 ± 35.80 months. We selected 48 patients affected by SRP and 143 matched controls confirmed with PRP. The diameter of the most dilated limbs (arterial, venous, and apical) was measured in 16 images per subject. Statistical analysis was performed using nonparametric tests. The threshold values for capillary diameters associated with the development of SSc-associated SRP were determined through receiver-operating characteristic curves., Results: Mean capillary diameter values were significantly different for arterial, venous, and average diameters (mean value of arterial, venous, and apical) between patients with PRP and SRP (p < 0.0001). These alterations were found to be independent predictors for disease development (p = 0.015). Threshold values of 30 µm (area under the curve = 0.802, sensitivity/specificity = 0.85/0.63) to 31 µm were identified for average, arterial, and venous diameters, with a shortening effect on time to disease development., Conclusion: The study showed that capillary diameter is an independent predictor for development of SSc-associated SRP. Progression to SRP is unlikely for subjects affected by RP when average capillary diameter is under 30 μm. Subsequently, the execution of the qualitative/quantitative integrated analysis should be part of the NVC followup of RP subjects.
