Real-life effectiveness and safety of guselkumab in patients with psoriasis who have an inadequate response to ustekinumab: A 104-week multicenter retrospective study - IL PSO (ITALIAN LANDSCAPE PSORIASIS).

BACKGROUND: Guselkumab is a fully human monoclonal antibody that binds selectively to the p19 subunit of interleukin-23, which has shown efficacy in patients with previous incomplete response to ustekinumab in the NAVIGATE clinical trial. [Correction added on [28-02-2023], after first online publication: 'humanized monoclonal antibody' has been changed to 'fully human monoclonal antibody' in the preceding sentence.] OBJECTIVES: We conducted a 104-week multicenter retrospective study to assess the effectiveness and safety of guselkumab in patients affected by plaque psoriasis with an inadequate response to ustekinumab in a real-life setting. METHODS: Our retrospective study included 233 adults affected by moderate-to-severe plaque psoriasis, enrolled in 14 different Italian centres, and treated with guselkumab after failing therapy with ustekinumab. Patient characteristics and PASI (Psoriasis Area and Severity Index) score at each visit (baseline, weeks 16, 52 and 104) were recorded. The percentages of patients achieving 75%, 90% and 100% (PASI 75, PASI 90 and PASI 100) improvement in PASI, compared with baseline, were registered. RESULTS: At week 52, PASI 75 was reached by 89.88% of patients, PASI 90 by 71.43%, PASI 100 by 58.83% and absolute PASI ≤2 by 90.48%. At week 104, similar effectiveness results were observed. Compared to the NAVIGATE trial, we observed higher rates of PASI 75/90/100. Patients with the involvement of difficult-to-treat areas were significantly less likely to achieve PASI90 and PASI100 at week 16. Obese patients had significantly lower rates of PASI75 and PASI ≤2 at week 52. At week 104, comparable responses were observed among all patients' subgroups, regardless of BMI status, involvement of difficult-to-treat areas, presence of cardiometabolic comorbidities and concomitant psoriatic arthritis. No significant safety findings were reported throughout the study. CONCLUSION: Our data suggest that the efficacy of guselkumab in patients with inadequate response to ustekinumab for plaque psoriasis in 'real-life' clinical practice is comparable with NAVIGATE study with higher percentages of patients achieving PASI90 and PASI100 at weeks 16, 52 and 104.

Tildrakizumab in moderate-to-severe plaque psoriasis: A multicenter, retrospective, real-life study.

New biologic agents targeting interleukin (IL)23/T-helper17 axis, such as tildrakizumab, have been developed for the treatment of plaque psoriasis. To analyze the efficacy and safety of tildrakizumab in a real life setting of patients affected by moderate-to-severe psoriasis over a 28-week treatment period. A multicentric retrospective study was conducted in patients who initiated tildrakizumab between February 2020 and March 2021. Psoriasis Area and Severity Index-PASI was measured at baseline and after 4, 16 and 28 weeks. The percentage change in PASI value from baseline to the considered time-points, proportion of patients with absolute PASI <3 at week 28 and the percentages of achieving a PASI75 or PASI90 response were assessed. Data about potential safety issues and adverse events (AEs) were collected. Statistical analysis were performed for establish clinical efficacy and for variables predicting clinical response. Fifty nine patients with psoriasis were included. Overall mean PASI percentage reduction was of 88% from baseline to week 28 and 47 out of 59 patients (79.7%) at week 28 had an absolute PASI <3. PASI75 and PASI90 responses at week 28 were achieved by 48 (81.40%) patients and 38 (64.4.0%) patients, respectively. No substantial associations between gender, body mass index - BMI, PASI at baseline and prior exposition to biological therapies and the efficacy endpoints were retrieved. No serious safety issues or discontinuations related to adverse events were reported. In our real-life study, tildrakizumab showed high efficacy and a favorable safety profile, regardless of patient- and disease-related factors.

Management of patients with atopic dermatitis undergoing systemic therapy during COVID-19 pandemic in Italy: Data from the DA-COVID-19 registry.

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.

Secukinumab Exhibits Sustained and Stable Response in Patients with Moderate-to-Severe Psoriasis: Results from the SUPREME Study.

Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in terms of Psoriasis Area and Severity Index (PASI) 90 in patients with moderate-to-severe plaque psoriasis. Based on PASI 90 response at week 16, patients were stratified as PASI 90 responders (PASI90R, n = 337) or non-responders (PASI90NR, n = 72). At week 20, 94.2% (n = 295/313) achieved PASI 90/100 response in PASI90R, with response maintained through week 48 (89.6%, n = 189/211). An increased proportion of patients achieved PASI 90/100 response in PASI90NR (week 20: 29.9%, n = 20/67; week 48: 57.1%, n = 20/35). Overall, 64.4% patients achieved absolute PASI score = 0 at week 24 with response sustained to week 48 (66.9%). Secukinumab showed sustained and stable efficacy in maintaining PASI 90 response in patients with moderate-to-severe plaque psoriasis up to week 48.

Biologic therapy for acrodermatitis continua of Hallopeau: Successful treatment with secukinumab and review of the literature.

Acrodermatitis continua of Hallopeau (ACH) is a rare pustular psoriasis variant refractory to many conventional treatments. We report the successful treatment with secukinumab of a patient with a long history of ACH with marked onychodystrophy with frank pustulosis on the nail bed and with accompanying arthritis. Blockade of the IL-17 receptor A has shown promise in the treatment of psoriatic erythroderma and generalized pustular psoriasis not responsive to conventional treatment. A rapid response was observed in our patient, in both skin lesions and arthritic symptoms, underlining the ability of secukinumab to improve symptoms beyond those of plaque psoriasis.

Successful treatment of psoriatic crumbly nails with ustekinumab.

Nail involvement can place a significant burden on patients as a result of functional damage and psychosocial problems, leading to major repercussions on the quality of life. There is strong evidence that nail psoriasis can often be difficult to treat. We report a 69-year-old man with severe onychodystrophy, onycholysis, and pain in the hands; he had been previously treated with topical and systemic traditional therapies without satisfactory response. The patient showed multiple severe psoriatic crumbly nails (nail psoriasis severity index [NAPSI] score of 69) and started ustekinumab treatment at standard dosage of 45 mg fl.s.c. After 24 weeks, both nail matrix and nail bed disease showed marked improvement and the patient continued therapy with ustekinumab (NAPSI 0 at week 104). At week 136 (September 2015), the patient had been complaining of hands pain (visual analogue scale pain: 80) and ultrasonographic (US) evaluations found a synovial proliferation with effusion on metacarpophalangeal joints. The patient continued therapy with ustekinumab, adding methotrexate 10 mg fl.s.c/week. In November 2016, the patient showed a remission of symptoms; clinical and US evaluations did not find signs of synovitis. Methotrexate treatment was suspended and currently the patient reached more than 4 years of ustekinumab treatment without sign and symptoms of synovitis.

Alexithymia and Plaque Psoriasis: Preliminary Investigation in a Clinical Sample of 250 Patients.

BACKGROUND/AIMS: Psoriasis as a dermatological disorder has complex effects on mental health and the psychological status of the patient. Many authors proposed that assessing how psoriasis affects a patient's life is better than a body surface area measurement for delineating psoriasis severity. Alexithymia is a personality dimension characterized by difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking observed in many clinical conditions, especially in psychosomatic disorders. This study aimed to determine the prevalence of alexithymia in patients with plaque psoriasis compared with healthy participants, while taking into consideration demographic and clinical variables. METHODS: We enrolled 250 patients with chronic plaque psoriasis, naïve to any systemic treatment, and 215 healthy individuals. The 20-item Toronto Alexithymia Scale (TAS-20) was used to assess alexithymia. Data analysis was done. RESULTS: The mean TAS score was 53.5 (±15.3) for the patient group and 45.1 (±10.8) for controls (p < 0.0001). Compared to controls, the psoriasis group showed significant alexithymic features (32.4 vs. 9.3%), and no significant differences of alexithymia between patients with severe and mild psoriasis were observed. A significant relationship was determined between alexithymia and female gender and sensitive area involvement, such as the face, hands, and genital area. CONCLUSION: This study suggests that the assessment of alexithymia should be a part of the comprehensive care of patients with moderate to severe psoriasis. For this purpose, the TAS-20 is a useful and simple tool to be used in daily clinical practice.

IL12B (p40) Gene Polymorphisms Contribute to Ustekinumab Response Prediction in Psoriasis.

BACKGROUND: Psoriasis is characterized by multiple genetic variations. Some of these variations, such as the presence of HLA-Cw6 or TNFAIP3 single-nucleotide polymorphisms (SNPs), have been correlated to the response to biologic treatments. OBJECTIVE: The aim of our study was to evaluate the effects of IL12B and IL6 SNPs on the response to ustekinumab. METHODS: We retrospectively analyzed the genotypes of 64 patients who had been treated with ustekinumab for up to 1 year. Efficacy data were evaluated using 'intention to treat-last observation carried forward' analysis. RESULTS: We confirmed the positive role of HLA-Cw6 as a predictor of the response to ustekinumab and discovered that presence of the GG genotype on the IL12B rs6887695 SNP and absence of the AA genotype on the IL12B rs3212227 SNP significantly increase the probability of therapeutic success in HLA-Cw6 positive patients. CONCLUSIONS: The availability of pharmacogenetic data will influence therapeutic decisions in the clinical management of psoriatic patients.

What happened after the clinical trials: long-term safety and efficacy of ustekinumab in daily clinical practice.

BACKGROUND: Ustekinumab has been investigated in patients with psoriasis by randomized clinical trials. There are few data on ustekinumab use under 'real life' conditions outside long-term registries. OBJECTIVE: The aim of our study was to evaluate the efficacy and safety of ustekinumab as a long-term therapy in real life. METHODS: We retrospectively analyzed the data of 71 patients who had been treated with ustekinumab up to 2 years. Efficacy data were analyzed both by 'as treated' and 'intention to treat-last observation carried forward'. RESULTS: A significant improvement in the Psoriasis Area and Severity Index score was observed at 4 weeks and further improvements were observed throughout the treatment. Adverse events were generally mild. CONCLUSIONS: In routine administration ustekinumab seems to be more efficient than reported by randomized clinical trials. Our results are encouraging and can answer the patients' biggest concern on whether ustekinumab is an effective and safe drug for long-term use.

Successful long-term guselkumab treatment of severe plaque psoriasis in patients with class III obesity: A case series.

Data from real-world studies and clinical trials have documented the long-term efficacy and safety of guselkumab in patients with moderate-to-severe psoriasis. Limited data are available on the long-term use of guselkumab in morbidly obese individuals with severe psoriasis. Here, we present data on the outcome of three patients with class III obesity (body mass index (BMI) of ≥40 kg/m2) with severe plaque psoriasis treated with 100 mg guselkumab. At baseline, mean BMI was 46.5 ± 5.4 kg/m2 and mean PASI was 46.0 ± 18.5 and all patients were biologic naïve. After 12 weeks of guselkumab treatment, mean PASI decreased to 9.7 ± 4 and to 4.0 ± 1.7 at 28 weeks. After 1 year, two patients achieved complete remission and one patient had PASI of 6 (achieving remission by week 140). All three patients are still in complete remission. Our real-life results in specific patients burdened with class III obesity naïve to biologic treatment show excellent long-term psoriasis outcome with guselkumab.

Dupilumab for Treatment of Prurigo Nodularis: Real-Life Effectiveness for up to 84 Weeks.

(1) Background: Prurigo nodularis (PN) is a persistent and inflammatory dermatological condition characterized by chronic itching and the formation of hardened nodules, significantly impacting the affected individuals' quality of life and psychological well-being. The management of PN poses challenges due to the limited efficacy and undesirable side effects associated with current interventions. (2) Methods: This article examines sixteen patients affected by PN treated with dupilumab, a fully human monoclonal antibody targeting interleukin IL-4 and IL-13 signaling. This involves a retrospective descriptive statistical analysis. (3) Results and (4) Conclusions: In all patients, dupilumab proves to be an effective drug in achieving disease clearance, as indicated by all the parameters considered as assessed by both physicians and patients at each evaluation point (Week 6, Week 16, Week 32, Week 52, Week 68, and Week 84), in comparison to the initial baseline.

A Multidisciplinary Approach Is Beneficial in Atopic Dermatitis.

Atopic dermatitis (AD) is a highly heterogeneous chronic inflammatory skin disorder that is frequently associated with a plethora of comorbidities. AD is, therefore, considered a systemic disease impacted by a considerable burden and leading to poor quality of life, especially in patients with moderate-to-severe disease. Since atopic and non-atopic comorbidities can further worsen the disease course, accurate establishment of the patient's individual intrinsic risk profile and needs is crucial and may help in guiding the selection of the best treatment option. Better quality of care for patients with AD can be delivered through a multidisciplinary team led by a dermatologist, for comprehensive patient management. The implementation of a multidisciplinary approach for AD could enhance the delivery of optimised and safe treatments, improve the standard of care and patient outcomes in the short and long term, and prevent or delay the lifelong impact of uncontrolled AD. Understanding the unmet needs, assessing correctly the patient risk profile and enhancing the shared patient-physician decision-making process can lead to disease control and quality-of-life improvement, especially in the context of the introduction of newer treatment for AD. This narrative review is a call for more data to establish standardised patient profiles and multidisciplinary strategies in AD management. In view on the fast-evolving treatments for AD, this review aims at highlighting the importance of a multidisciplinary approach to a comprehensive assessment and holistic care in patients with moderate-to-severe AD.

Efficacy and Safety of Dupilumab in the Treatment of Hand Eczema: A Retrospective Study.

Background: Hand eczema (HE) is a prevalent chronic condition that exerts a substantial and enduring adverse effect on quality of life (QoL) and imposes an economic burden on society. Managing HE poses challenges due to the limited effectiveness and potential adverse effects associated with many currently available topical and systemic treatments. Methods: This article examines twenty-one patients affected by HE treated with dupilumab, a fully human monoclonal antibody targeting interleukin IL-4 and IL-13 signaling. This involves a retrospective descriptive statistical analysis. Results: At week 6, HECSI-75 was achieved by 12 patients (57.9%). The proportion of patients meeting the HECSI-75 criteria steadily increased over the observation weeks, reaching 90% at week 16 and 100% at week 104. Furthermore, HECSI-90 and HECSI-100 were achieved by 75% and 60% of patients at week 16 and by 100% and 85% of patients at week 68, respectively. All patients who reached week 104 maintained complete disease remission according to HECSI 100. Conclusions: In all patients, dupilumab was shown to be an effective drug in achieving disease clearance, as indicated by all the parameters considered at each evaluation point (Week 6, Week 16, Week 32, Week 52, Week 68, Week 84, and Week 104), in comparison to the initial baseline.

Dupilumab-associated ocular surface disease or atopic keratoconjunctivitis not improved by dupilumab? Upadacitinib may clarify the dilemma: A case report.

Dupilumab-associated ocular surface disease is a common clinical sign appearing in patients with atopic dermatitis (AD) just few months after dupilumab treatment start, developing in about 25% of patients. Atopic keratoconjunctivitis (AKC) is a well-identified clinical entity, defined as a chronic inflammatory disease of eye that affects 25%-40% of patients with AD. Most clinical signs of ocular involvement in AD patients treated with dupilumab overlaps the AKC symptoms and signs. We supposed that Dupilumab-associated ocular surface disease and AKC represent the same disease but differently called by dermatologists and ophthalmologists. AKC-like disease may develop during dupilumab therapy as a consequence of alternative cytokines pathway activation (e.g. IL33) secondary to IL-4/13 pathway block. The novel upadacitinib drug may bypass ILs pathway through Janus Kinases selective inhibition, avoiding positive or negative ILs feedback at the ocular surface level. In this case report, molecular analysis on conjunctival samples showed a lower ocular surface inflammation (lower expression of HLADR) although higher levels of IL4 and IL13 in a patient with AD and AKC during upadacitinib therapy, compared to prior dupilumab treatment. Target therapies in patients suffering from AD may prevent ocular and dermatological comorbidities improving quality of life before quality of skin and vision.

Long-Term Effectiveness of Brodalumab for the Treatment of Moderate-To-Severe Psoriasis: A Real-Life Multicenter Study of Up to 3 Years in a Real-Life Italian Cohort.

INTRODUCTION: Data about the long-term effectiveness of brodalumab could be valuable in assessing patient adherence to treatment and improving psoriasis management. OBJECTIVE: The aim of our study was to evaluate the drug survival of brodalumab and identify any predictive factors for discontinuation. METHODS: A multicenter retrospective study was conducted in patients with moderate-to-severe psoriasis who were treated for up to 3 years. We extracted data from patient files, related to the characteristics of the patients and the disease. Drug survival analysis was descriptively analyzed using Kaplan-Meier survival curves. Univariable and multivariable analyses were performed to assess baseline patient characteristics that predicted clinical response. RESULTS: The study included 90 patients. Among them, 28 (31.1%) suspended brodalumab through the observation period. At weeks 52, 104 and 156 the median PASI score were 0.0 [0.0 - 0.8], 0.0 [0.0 - 1.0] and 0.0 [0.0 - 0.0], respectively. The estimated cumulative survival rates at weeks 52 and 104 were 86.32% and 78.09%, respectively. In the multivariable survival analysis, predictor factors for overall discontinuation included body mass index (BMI) (OR 1.10, 95% CI 1.03 - 1.18), baseline PASI (OR 1.06, 95% CI 1.02 - 1.10), and psoriatic arthritis (OR 5.05, 95% CI 0.89 - 13.50). CONCLUSIONS: Brodalumab has shown long-term effectiveness for up to 3 years. Considering baseline disease severity and patient characteristics could aid in optimizing the long-term management of psoriasis.

Anti-Herpes zoster vaccination in patients with dermatologic diseases: a position statement from the Italian SIDeMaST group of sexually transmitted, infectious and tropical diseases.

Herpes zoster (HZ) is a condition caused by the reactivation of varicella-zoster virus (VZV), the virus responsible for chickepox, which is the clinical manifestation of the primary infection. Congenital or acquired immune system deficiencies, as well as the physiological decline in immune response occurring in the elderly, known as immune senescence, can allow VZV reactivation and, consequently, HZ. One out of 3 people develops HZ during their lifetime. Moreover, thirty percent of the affected subjects develop post-herpetic neuralgia, the most frequent complication after HZ skin rash. Patients with dermatological conditions characterized by alteration of the immune system, such as systemic lupus erythematosus, psoriasis, atopic dermatitis, bullous diseases, and cutaneous lymphomas, are at higher risk of developing HZ and post-herpetic neuralgia, even when their disease is in remission. In the present work, we described the currently available vaccinations against HZ and provided recommendations for the vaccination against HZ in patients with dermatological diseases.

Evaluating the Clinical Meaning of Dermatology Life Quality Index Scores Between Different Phenotypes of Atopic Dermatitis in Patients Before and After Biologic Therapy With Dupilumab.

Background and Objective: Atopic Dermatitis (AD) is the most prevalent inflammatory skin disorder resulting in an intense impact on patients quality of life. The aim of this study is to evaluate the clinical meaning of the DLQI scores documented between different phenotypes of AD patients under biologic therapy with Dupilumab. Method: We conducted a retrospective analysis of 209 patients with AD treated with Dupilumab for 2 years. These patients were categorized into different clinical phenotypes. Severity of the disease was assessed by using the Eczema Area and Severity Index (EASI), Numerical Scale Rating (NRS) for sleep (NRS sleep), pruritus (NRS pruritus) and Dermatology Life Quality Index (DLQI) at baseline and subsequently at 4,12 and 24 months. Results: Our results show that the higher DLQI scores (mean: 18.6, range:9-30) achieved at T0 are associated with a prurigo nodularis AD pattern, while after 24 months (T3) of therapy with Dupilumab, the worst quality of life index results were reported in Flexural and Head-Neck combined clinical phenotypes. Conclusions: Quality of life is probably what matters most as an overall endpoint in AD. Assessing the clinical meaning of DLQI scores across different AD phenotypes could be a further aid when considering decision making factors in patient management.

Efficacy and safety of tildrakizumab in elderly patients: real-world multicenter study (ESTER - study).

Purpose of the article: Interleukin-23 inhibitors, such as tildrakizumab, have emerged as safe and effective options for the management of psoriasis. Yet their efficacy in elderly patients (aged 65 years or more), particularly in those with difficult-to-treat areas involvement, remains insufficiently explored. We conducted this real-life retrospective multicentric observational study to assess the effectiveness of tildrakizumab in elderly patients with moderate-to-severe psoriasis, with involvement of difficult-to-treat areas.Materials and methods: We enrolled forty-nine patients aged 65 years old or more (mean age 73.1 ± 6.0), all treated with tildrakizumab for at least 28 weeks. The effectiveness of tildrakizumab was assessed by Static Physician's Global Assessment of Genitalia (sPGA-G), fingernail-PGA (f-PGA), palmoplantar PGA (pp-PGA), scalp-specific PGA (sc-PGA), and Psoriasis Area and Severity Index (PASI) scores.Results: Significant improvements in PASI scores were observed within 28 weeks of treatment, with 77.5%, 60%, and 45.2% of patients achieving PASI75, PASI90, and PASI100, respectively. The mean PASI decreased significantly from baseline (13.6 ± 9.9) to 1.3 ± 1.7 at week 28. More than 90% of patients had clear sPGA-G and pp-PGA scores and over 70% had clear f-PGA and sc-PGA scores after 28 weeks.Conclusions: Our findings suggest that tildrakizumab could be a valuable option for the treatment of elderly patients, including those with difficult-to-treat areas involvement.
