A severe psoriasis flare after COVID-19 treated with risankizumab: complete skin clearance after 16 weeks.

The development of flares or new-onset of immune-mediated dermatologic diseases, including psoriasis, has occurred with the worldwide spreading of the COVID-19 pandemic. We report the case of a 38-year-old woman who came to our department with a severe flare of plaque psoriasis four weeks after SARS-CoV-2 infection. Her Psoriasis Area Severity Index was 25, and her Dermatology Life Quality Index was 18. Our initial decision was to prescribe acitretin, but the patients reported adverse events. For this reason, we started risankizumab with complete skin clearance after 16 weeks. The patient is still on treatment, and no adverse events have been reported to date.

Upadacitinib for the treatment of concomitant psoriasis and atopic dermatitis: a case series.

Purpose: The overlap of psoriasis and atopic dermatitis (AD) is rare and treating moderate-to-severe cases can be challenging. Conventional immune-suppressive drugs cannot be used long-term, and no biological drugs are currently approved for treating both conditions.Method: We report the cases of four patients with overlapping features of both psoriasis and AD.Result: After being treated with several systemic drugs, including gold-standard treatments for both psoriasis and AD, they received upadacitinib 15 or 30 mg, achieving complete remission. Upadacitinib is an inhibitor of Janus Kinase 1, currently approved for treating moderate-to-severe AD.Conclusion: To date, very limited data are available regarding the efficacy of upadacitinib in psoriasis. In a phase-3 trial on the efficacy of upadacitinib 15 mg in patients affected by psoriatic arthritis, 52.3% of patients achieved a 75% improvement in Psoriasis Area and Severity Index (PASI75) after one year. Currently, no clinical trials are evaluating the efficacy of upadacitinib in plaque psoriasis.

Real-Life Effectiveness and Safety of Risankizumab in 131 Patients Affected by Moderate-to-Severe Plaque Psoriasis: A 52-Week Retrospective Study.

INTRODUCTION: Risankizumab is a humanized monoclonal antibody that selectively targets interleukin-23. It is approved for treatment of moderate-to-severe plaque psoriasis. We conducted a 52-week monocentric retrospective study to evaluate the effectiveness and safety of risankizumab in a real-life setting. METHODS: Our study included 131 adults with moderate-to-severe plaque psoriasis all treated with risankizumab for at least 52 weeks. Patient characteristics and PASI (Psoriasis Area and Severity Index) at each visit were recorded. The percentages of patients achieving 75%/90%/100% (PASI 75/90/100) improvement in PASI with respect to baseline were registered. RESULTS: At week 52, 93.9%, 78.6%, and 61.1% of patients achieved PASI 75/90/100, respectively. An absolute PASI ≤ 2 was reached by 90.8% at week 52. The higher body mass index and the presence of cardio-metabolic comorbidities did not interfere with the odds of reaching PASI 75/90/100 at each time-point. At week 52, comparable percentages of patients achieved PASI 100, regardless of the involvement of difficult-to-treat-areas. No significant safety findings were recorded and none of the patients had to interrupt the treatment because of adverse events. CONCLUSIONS: Our findings confirmed that risankizumab is a safe and effective therapeutic option for the treatment of a wide "real-life" cohort of patients with psoriasis.

Real life long-term efficacy and safety of ixekizumab in moderate-to-severe psoriasis: A 192 weeks multicentric retrospective study-IL PSO (Italian landscape psoriasis).

Psoriasis is one of the commonest inflammatory skin diseases determining a very high impact on patients' quality of life and daily activities and relationships. Several biologic therapies have been approved through the years for the treatment of moderate-to-severe plaque psoriasis, and efficacy and safety profile have been analyzed in clinical trials. Ixekizumab is an immunoglobulin G subclass 4 monoclonal antibody that selectively targets and binds IL-17A with high specificity and affinity. Inhibiting IL-17A activity, ixekizumab reduces and turns down levels of inflammation, resulting in the clinical improvement of the disease. Long-term efficacy and safety profile of ixekizumab have been investigated and reported in the UNCOVER trials, but in literature there are only few studies based on real life experience. We present the efficacy and safety profile of ixekizumab in a cohort of 779 patients affected by moderate-to-severe plaque psoriasis and treated with ixekizumab in 11 Italian dermatology hospitals, with a follow-up of care until 192 weeks.

What Can IBD Specialists Learn from IL-23 Trials in Dermatology?

BACKGROUND AND AIMS: The advent of biologic drugs revolutionised the treatment of many chronic inflammatory diseases in rheumatology, dermatology, and gastroenterology. The introduction of different targeted agents closely followed the increase in knowledge of pathogenic mechanisms. The identification of IL-23 as a master regulator of 'pathogenic' inflammation and the consequent efficacy of IL-23 blocking agents were first proofed in psoriasis and then in other inflammatory diseases such as psoriatic arthritis and Crohn's disease. METHODS: We reviewed all available results from anti-Il-23 clinical trials for psoriasis, focusing on data of IBDologists' interest. Regarding guselkumab, we analysed data from phase III clinical trials VOYAGE1, VOYAGE2, and NAVIGATE. For risankizumab, we reported efficacy and safety results from UltIMMa-1, UltIMMa-2, and IMMvent clinical trials, and tildrakizumab was evaluated by analysing data from reSURFACE1 and reSURFACE2 studies. RESULTS: Data from all the clinical trials that we reported showed both the efficacy of all three anti-IL-23 drugs in psoriasis and the safety of this class; in particular, no gastrointestinal side effects were observed in those studies. IL-23 blockers have shown promising short- and long-term results in psoriasis, with a major safety profile and no negative interactions with gastrointestinal system. CONCLUSIONS: Anti-IL-23 indication for psoriatic arthritis is very recent and for IBD is still to come. Therefore, dermatologists are accumulating long-term experience with these drugs, both in clinical trials and in real-world evidence, which can help gastroenterologists in the management of IBD patients.

Safety of Biologic Therapies in Patients with Moderate-to-Severe Plaque Psoriasis and Concomitant Viral Hepatitis: A Monocentric Retrospective Study.

INTRODUCTION: There are no strong data regarding the treatment with biologics (especially for the most recent anti-IL-17 and anti-IL-23 drugs) of patients with psoriasis and concomitant viral hepatitis. We assessed the safety of biologic drugs in patients with psoriasis who are seropositive for hepatitis B or C and did not receive antiviral prophylaxis. METHODS: We conducted a retrospective single-center study. The efficacy of biologic treatments was evaluated by assessing the Psoriasis Area and Severity Index (PASI) score during all visits, for a minimum follow-up of 52 weeks. All patients were evaluated by a hepatologist before starting the treatment. They were monitored for reactivation of viral hepatitis. RESULTS: Twenty patients had positive markers of hepatitis B virus (HBV) or hepatitis C virus (HCV). Seventeen patients had positive markers of HBV infection, and four patients had antibodies for HCV (one patient had serologic evidence of both infections). Anti-IL-23 biologics were the most used in our population, with risankizumab being the most prescribed drug. No patient had evidence of viral reactivation during our study. Study limitations include its retrospective nature and our inclusion of patients with different serological status receiving different biologic drugs. CONCLUSION: Biologic therapies (including anti-IL-23 drugs) appear to be safe in patients seropositive for HCV or HBV core antibody who did not receive antiviral prophylaxis.

Anti-IL17 and anti-IL23 biologic drugs for scalp psoriasis: A single-center retrospective comparative study.

Scalp is a frequent localization of psoriasis that has a massive impact on patient's quality of life. Managing this psoriasis' manifestation is often challenging, thus biologic drugs are widely used as a treatment option in refractory scalp psoriasis. The aim of our study is to retrospectively compare the efficacy of anti-interleukin (IL) 23 drugs (guselkumab, tildrakizumab, risankizumab) and anti-IL17 or anti-IL17RA biologics (secukinumab, ixekizumab, and brodalumab) in real-life patients affected by scalp psoriasis. One hundred twenty-seven patients with a clinical diagnosis of scalp psoriasis and a baseline scalp Physician Global Assessment ≥3 were enrolled; 65 patients were treated with anti-IL23 and anti-IL62 with anti-IL17 or anti-IL17RA. Statistical analysis trough χ2 test was performed in order to evaluate the percentage of response among the two groups of patients. Responders' percentage of patients under anti-IL23 was 41.5%, 75.4%, 88.1%, 87.5%, 93.7%, and 100% at Week 4, 16, 48, 96, and 144, respectively. In the group on anti-IL17 was 62.9%, 90.3%, 91.2%, 97.3%, 96.9%, and 95.2% at Week 4, 16, 48, 96, and 144, respectively. Both anti-IL17 and anti-IL23 appeared to be effective on scalp psoriasis; in particular patients treated with anti-IL17 drugs reached a faster significant reduction of the lesions; on the other hand, anti-IL23 monoclonal antibodies were slightly superior in maintaining the clinical improvement through the follow-up.

Apremilast for the treatment of palmo-plantar non-pustular psoriasis: A real-life single-center retrospective study.

Palmoplantar psoriasis (PP) is a type of psoriasis that involves the skin of the palms and soles and can present as hyperkeratotic, similar to the vulgaris psoriasis of the body. Apremilast, as an oral inhibitor of phosphodiesterase 4 (PDE4), is currently approved for the treatment of psoriatic arthritis and for moderate-to-severe psoriasis in adult patients who have not responded or have contraindications or do not tolerate other systemic treatments. We evaluated the efficacy and safety of apremilast in the treatment of non-pustular palmo-plantar psoriasis in a cohort of 12 patients. We found a clinical response of clear/almost clear palmoplantar psoriasis (PPPGA score 0/1) in 83.33% of our patients, at week 16. No significant safety issues were reported and none of our patients had to discontinue the drug.

Real-life Effectiveness and Safety of Risankizumab in Moderate-to-severe Plaque Psoriasis: A 40-week Multicentric Retrospective Study.

Risankizumab is a humanized monoclonal antibody that binds the p19 subunit of interleukin-23. It is approved for treatment of moderate-severe chronic plaque psoriasis. This retrospective study included 66 consecutive adults with moderate-to-severe psoriasis vulgaris treated with risankizumab in monotherapy up to week 40 in a "real-life" setting. At week 40, 98.7%, 85.7% and 62.3% of patients achieved a Psoriasis Area and Severity Index (PASI) reduction ≥ 75% (PASI 75), PASI 90 and PASI 100, respectively. Patients who had not responded to 2 or more previous biologic treatments were significantly less likely to achieve PASI 75/90 at week 16 and PASI 90/100 at week 40 compared with those who had been previously treated with only 1 biologic, and compared with those treated with risankizumab as a first-line biologic. Increasing body mass index decreased the chances of reaching PASI 90 at week 40. No significant safety findings were recorded throughout the study, and none of the patients had to interrupt the treatment. These data suggest that the efficacy of risankizumab for plaque psoriasis in "real-life" clinical practice could differ from pivotal clinical trials data.

Connective tissue panniculitis and vitiligo in a patient with stage IV melanoma achieving complete response to dabrafenib and trametinib combination therapy.

The combination of BRAF and MEK inhibitors, such as dabrafenib and trametinib, respectively, is an established treatment option for patients with advanced BRAFV600-mutated melanoma. With the wide adoption of these therapies, a range of cutaneous adverse effects has been reported. We describe the case of a 47-year-old woman with BRAFV600E-mutated stage IV melanoma treated with dabrafenib and trametinib for 30 months who presented to our attention for painful skin lesions that had been present on her limbs since the start of targeted therapy. We also observed vitiligo-like lesions on the extensor surface of both legs. Despite achieving a complete oncological response, the patient had to discontinue the treatment because of persisting fever, nausea and painful skin nodules that significantly impaired her quality of life. The recognition of cutaneous signs of efficacy of such drugs for advanced melanoma is of primary importance in order to identify patients with potential long-term clinical benefits.

Impact of delay in follow-up due to COVID-19 pandemic on skin cancer progression: a real-life experience from an Italian hub hospital.

BACKGROUND: The COVID-19 pandemic required the setting of a national lockdown in Italy from March 9, 2020, until May 18, 2020; therefore, most of the non-COVID-19 activities were postponed. As a consequence, many follow-up visits in patients with previously excised skin cancers were delayed. The aim of this retrospective real-life case-control study is demonstrating that delay in follow-up led to an increased incidence of advanced melanoma and keratinocyte cancers on the total of surgically excised skin cancers. METHODS: The incidence of excised advanced melanoma and keratinocyte cancers in our dermato-surgery division in the period May 18 to November 18, 2020, was compared to the same time span of 2019. All data were collected from the electronic database of our department. Odds ratio with 95% confidence interval was used to assess the risk of excised advanced skin cancers in 2020 compared to 2019. RESULTS: From May to November 2019, we performed 265 surgical excisions, while during the pandemic in 2020, we completed 280 surgeries. The number of advanced skin cancers excised between May 18 and November 18, 2020, was significantly higher compared with the same period in 2019 (54 vs. 22, OR: 2.64; 95% CI: 1.56-4.47; P = 0.0003). Significant differences were also observed regarding the number of surgically removed advanced BCCs (OR 2.15; 95% CI 1.14-4.07; P = 0.0187) and advanced SCCs (OR 4.60; 95% CI 1.31-16.18; P = 0.0175). CONCLUSION: These results confirm that delay in follow-up and, consequently, postponed surgical excisions are related to an increased incidence of advanced skin tumors, resulting in poorer prognosis lifelong. Follow-up visits should be carried on even during COVID-19 pandemic, avoiding significant delays as much as possible.
