Background/Objectives: Patients with treated solid tumors (TST) are a highly heterogeneous and difficult-to-treat population due to the risk of disease progression/recurrence or infection. Methods: We conducted an observational, retrospective, single-center study at the Dermatology Clinic of Turin with a focus on the special population of cancer patients with psoriasis treated with biologics. Results: As of July 2023, 52 psoriatic patients with a prior/concomitant history of malignancy had taken biologic drugs. The median age was 67 years, and the median age of cancer onset was 55 years. The most common tumors were gastrointestinal cancer and melanoma. After the tumor diagnosis, 61% received an anti-IL17 drug; 37 patients continued the initiated biologic therapy, while 12 switched drugs due to secondary inefficacy. The estimated biologic DS was 55.6% at 50 months. Evidence suggests that IL-17 is a key pathogenic factor involved in tumorigenesis, resulting in a lower risk of malignancies in subjects managed with IL-17 inhibitors. Similarly, IL-23 plays a role in suppressing innate immunity and promoting tumor and metastases development. This is a consistent real-life case series that support the use of biologic drugs in patients with TST. Conclusions: IL-23 and IL-17 inhibitors, being immunomodulators rather than immunosuppressants, may be a safe option for patients in an active oncological setting and for immune-correlated adverse events.

Background: Brodalumab is a monoclonal antibody and IL‐17 RA inhibitor that is approved for the treatment of moderate‐to‐severe psoriasis. The present study aims to estimate the drug survival (DS), effectiveness, and safety of brodalumab over a period of 156 weeks. Methods: The primary objectives were: (i) to determine the treatment response rate at Weeks 16, 28, 52, 78, 104, and 156 as defined by PASI100, PASI90, and an absolute PASI ≤ 3 and (ii) long‐term DS. Secondary objectives included the evaluation of possible predictive factors associated with the achievement of response outcomes, and possible predictive factors associated with lower DS. Results: The treatment response was rapid, with 80.3% of patients achieving PASI ≤ 3, 66% PASI90, and 54.3% the complete clearance of disease at Week 16. The response improved at Week 28, when a plateau was achieved with mild loss of response at later time points, in particular for PASI100 and PASI90 in 55.2 and 65.5% of patients, respectively, at Week 156. After 156 weeks of treatment, 66.22% of patients were still on therapy, and the previous use of IL‐17 inhibitors appeared to be associated with an increased risk of treatment discontinuation (HR: 2.51, CI: 1.06–5.98, P = 0.037), and achievement of PASI ≤ 3 until Week 16 with less risk (HR: 0.27 CI: 0.14–0.51, P < 0.001). Bio‐naïve status was favorably associated with treatment response, while high BMI negatively affected the achievement of outcomes. Conclusion: Our study confirms the good effectiveness and favorable safety profile of brodalumab in a real‐world setting for up to 3 years of treatment. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Summary: 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. [ABSTRACT FROM AUTHOR]

PASI improvement of 90%, 100% and PASI <3 was registered for each on-treatment patient at 12, 24 and 48 weeks. Different mean PASI at baseline among the treatments limits the evidence on achievement of PASI <3 at earlier time points, and the analysis of observed cases reduces the strength of evidence.

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. 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. Psoriasis area severity index (PASI) and retention rates for adalimumab, secukinumab, guselkumab, ixekizumab, and brodalumab were analised. 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.

Furthermore, risankizumab shows the highest efficacy in achieving PASI 100, PASI 90 and PASI 75, while a noninferiority of tildrakizumab and guselkumab in the first 28 weeks was observed in terms of PASI < 3 and PASI 100-90, respectively. [Extracted from the article]

This article, published in Experimental Dermatology, discusses the concept of "superresponders" in the treatment of psoriasis with biologic drugs. Superresponders are patients who show a rapid and exceptional improvement with their first biological treatment. The study conducted at the Turin University Hospital analyzed psoriatic patients treated with IL17 and IL23 inhibitors and found that superresponders were typically younger, had lower body mass index (BMI), and had an earlier onset of psoriasis compared to non-superresponders. They also had lower rates of obesity and diabetes mellitus. The study suggests the need for further research to establish a shared definition of superresponders. [Extracted from the article]

Introduction: Neisseria gonorrhoeae (NG) antimicrobial susceptibility trends to azithromycin, cefixime and ceftriaxone were analyzed, from 2009 to 2016, to monitor changing antimicrobial susceptibility concomitant with the change in prescribing practice in 2012 from cefixime, or ceftriaxone, to ceftriaxone plus azithromycin. Patient characteristics predictive to be infected by antibiotic resistant N. gonorrhoeae were estimated. Finally, the protocol for the treatment of gonorrhoea, in comparison with the international guidelines, was also evaluated. Materials and methods: Data on NG antimicrobial resistance were obtained from a network of sexually transmitted diseases clinics and other laboratories in 12 cities in Italy. We tested the 1,433 gonococci for antimicrobial susceptibility to azithromycin, cefixime and ceftriaxone using a gradient diffusion method. Logistic-regression methods with cluster robust standard errors were used to investigate the association of resistance categories with demographic and clinical patient characteristics and to assess changes in prescribing practices. To minimize bias due to missing data, all statistical models were fitted to data with forty rounds of multiple imputation, using chained equations. Results: The percentage of isolates resistant to cefixime was 17.10% in 2009 and declined up to 1.39% in 2016; at the same time, those resistant to azithromycin was 23.68% in 2009 and 3.00% in 2012. Starting from 2013, azithromycin resistant gonococci tended to increase up to 7.44% in 2016. No ceftriaxone resistant isolates were observed. By multivariate analysis, the men who have sex with women (MSW) and women had a proportional adjusted OR of resistance of 1.25 (95%CI: 0.90; 1.73) and 1.67 (95%CI: 1.16; 2.40), respectively, in comparison with men who have sex with men (MSM). An aOR of resistance of 0.48 (95%CI: 0.21; 1.12) among NG isolated in the pharynx, compared with those isolated in genital sites, was calculated. The proportional aOR of resistance was 0.58 (95%CI: 0.38; 0.89) for presence vs absence of co-infection and 2.00 (95%CI: 1.36; 2.96) for past history vs no history of gonorrhoea.Finally, at least for the period 2013–2016, the older, subjects with anorectal or pharyngeal gonorrhoea infection, subjects with a co-infection, subjects with a previous gonorrhoea infection were not always correctly treated. Conclusions: Overall, our findings suggest the shifts in N. gonorrhoeae susceptibility to cefixime and azithromycin in the time frame period. First of all, the increasing rate of azithromycin resistance in 2015–2016 in NG isolated in the country need to be monitor in the future. Finally, extensive information on treatment regimens may be useful to asses treatment adherence particularly for the older subjects, subjects with an anorectal or pharyngeal infection, subjects with a co-infection and subjects with a previous history of gonorrhoea. Gonorrhoea treatment strategy should be based on the evidence obtained by the local antimicrobial surveillance system and data about treatment failures. [ABSTRACT FROM AUTHOR]

Background Materials and methods Results Conclusions 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.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.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.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. [ABSTRACT FROM AUTHOR]

Background: Although long-term management of psoriasis is paramount, this approach is challenging in clinical practice. In the recent PSO-LONG trial, a fixed-dose combination of betamethasone dipropionate (BD) and calcipotriol (Cal) foam applied twice a week on non-consecutive days for 52 weeks (proactive treatment) reduced the risk of relapse. However, the role of Cal/BD foam in the long-term management of psoriasis needs further clarifications. The ProActive Management (PAM) program, a nationwide Italian project, aims at reaching a consensus on the role of proactive management of psoriasis., Methods: A steering committee generated some statements through the nominal group technique (NGT). The statements were voted by an expert panel in an adapted Delphi voting process., Results: Eighteen statements were proposed, and the majority of them (14/18) reached a consensus during the Delphi voting. The need to provide long-term proactive topical treatment to reduce the risk of relapse for the treatment of challenging diseases sites or in patients where phototherapy or systemic therapies are contraindicated/ineffective was widely recognized. A consensus was reached about the possibility to associate the proactive treatment with systemic and biological therapies, without the need for dose intensification, thus favoring a prolonged remission. Moreover, the proactive treatment was recognized as more effective than weekend therapy in increasing time free from relapses. Approaches to improve adherence, on the other hand, need further investigation., Conclusions: The inclusion in guidelines of a proactive strategy among the effective treatment options will be a fundamental step in the evolution of a mild-moderate psoriasis therapeutic approach., (© 2022 The Authors.
