New-Onset Psoriatic Arthritis under Biologics in Psoriasis Patients: An Increasing Challenge?

Pathophysiology and Treatment of Psoriasis: From Clinical Practice to Basic Research

Psoriasis, a chronic inflammatory dermatosis, represents a significant clinical challenge due to its complex pathogenesis and the limitations of existing therapeutic strategies. Current psoriasis diagnoses are primarily clinician-dependent, with instrumental diagnostics serving as adjuncts. Ongoing research is progressively deciphering its molecular underpinnings; the future of psoriasis diagnostics may involve genetic and immunological profiling to pinpoint biomarkers, enabling more accurate and timely interventions. The administration of psoriasis medications, whether oral, injectable, or topical, is associated with a range of side effects and compliance issues. Topical medications, despite their advantages in patient compliance and reduced systemic side effects, are hindered by the altered skin barrier in psoriasis, which impedes effective drug penetration and retention. In recent years, the development of novel transdermal drug delivery systems represents a promising frontier in psoriasis management. Nanotechnology-, microneedle- and dressing-based systems have demonstrated the potential for improved skin penetration, enhanced bioavailability, or extended retention time. Here, we will focus on the latest insights into the etiology, diagnostic methodologies, and therapeutic approaches for psoriasis, with a particular emphasis on the evolution and challenges of novel transdermal drug delivery systems.

Efficacy and safety of deucravacitinib for the management of psoriasis: a drug safety evaluation

INTRODUCTION

Nowadays, despite the wide availability of biological drugs and apremilast for psoriasis management, there is always a need for new therapies to customize the therapeutic approach on the basis of the patient's clinical features and comorbidities, especially in order to achieve a prolonged therapeutic response. Thus, new treatment strategies are required to offer patients a personalized approach. In this scenario, major knowledge on psoriasis pathogenesis led to the development of deucravacitinib, an orally administered selective TYK2 inhibitor.

AREAS COVERED

The aim of this manuscript is to review the current literature on the effectiveness and safety of deucravacitinib in psoriasis to offer readers a wide perspective. The current English literature was analyzed using the PubMed, Google Scholar, Embase, Cochrane Skin, and clinicaltrials.gov databases, selecting the most relevant manuscripts.

EXPERT OPINION

Deucravacitinib appears to be an innovative weapon for the management of moderate to severe psoriasis. Despite its efficacy and safety profiles have been revealed by RCTs, real-life data are still scant. Certainly, deucravacitinib broadens the range of therapeutic alternatives for psoriasis patients, thus enhancing the holistic and personalized approaches required for the treatment of this disease.

Management of Psoriasis Patients with Serious Infectious Diseases

The management of patients affected by moderate-to-severe psoriasis may be challenging, in particular in patients with serious infectious diseases [tuberculosis (TB), hepatitis B and C, HIV, COVID-19]. Indeed, these infections should be ruled out before starting and during systemic treatment for psoriasis. Currently, four conventional systemic drugs (methotrexate, dimethyl fumarate, acitretin, cyclosporine), four classes of biologics (anti-tumour necrosis factor alpha, anti-interleukin (IL)12/23, anti-IL-17s, and anti-IL-23], and two oral small molecules (apremilast, deucravacitinib) have been licensed for the treatment of moderate-to-severe psoriasis. Each of these drugs is characterized by a unique safety profile which should be considered before starting therapy. Indeed, some comorbidities or risk factors may limit their use. In this context, the aim of this manuscript was to evaluate the management of patients affected by moderate-to-severe psoriasis with serious infectious diseases.

The Role of Interleukin 23/17 Axis in Psoriasis Management: A Comprehensive Review of Clinical Trials

Psoriasis pathogenesis is influenced by genetic factors and characterized by a complex interplay between genetic predisposition and various environmental triggers. These triggers set off metabolic processes involving inflammation, cell signaling, immune response dysregulation, and antigen presentation. Several types of innate and adaptive immune cells are involved in psoriasis. Among the cytokine cascade which leads to psoriasis development, the interleukin (IL)-23/Th17 axis, especially IL-17 production, emerges as crucial. Recognizing the pivotal role of this axis has facilitated the development of selective and effective biological drugs, such as anti-IL17 and anti-IL23 monoclonal antibodies. These drugs aim to achieve the complete or near-complete disappearance of psoriatic lesions, as indicated by PASI100 and PASI90 responses, respectively. In this context, the aim of our review was to delve into the functioning of the IL-23/Th17 axis, its dysregulation in psoriasis pathogenesis, and the therapeutic potential of its inhibition. Currently, 4 anti-IL17 (secukinumab, ixekizumab, bimekizumab and brodalumab) and 3 anti-IL23 (guselkumab, risankizumab and tildrakizumab) have been approved. All these drugs showed high levels of effectiveness in both clinical trials and real-life experiences, with an excellent profile in terms of safety. Certainly, furthers studies will allow for better characterization of biologics' profile, in order to administer the right drug for the right patients at the right moment.

Drug- or Vaccine-Induced/Aggravated Psoriatic Arthritis: A Systematic Review

INTRODUCTION

Drugs and vaccines have been less studied as inducing or aggravating factors for psoriatic arthritis (PsA) compared with psoriasis. Thus, the present study collected and summarized the publications to date about this issue.

METHODS

We conducted a systematic literature search through the PubMed, Embase, and Cochrane databases to identify all reports on potential drug- and vaccine-related PsA events until 28 February 2023.

RESULTS

In total, 179 cases from 79 studies were eligible for study. Drugs commonly reported include coronavirus disease 2019 (COVID-19) mRNA vaccines (6 cases), bacillus Calmette-Guerin (BCG) vaccine (3 cases), interferon (18 cases), immune-checkpoint inhibitors (ICI) (19 cases), and biologic disease-modifying antirheumatic drugs (bDMARDs) (127 cases). Drugs causing psoriasis may also induce or aggravate PsA (6 cases). BDMARD-related PsA mostly occurred in a "paradoxical" setting, in which the bDMARDs approved for the treatment of psoriasis induce or aggravate PsA. The reported latency may be delayed up to 2 years. Peripheral arthritis (82.3%) was the most common manifestation of drug- and vaccine-related PsA, followed by dactylitis (29.1%), enthesitis (23.4%), and spondyloarthritis (17.7%).

CONCLUSIONS

Drugs and vaccines may be implicated in the aggravation of PsA. Possible mechanisms include cytokine imbalance, immune dysregulation, or inadequate PsA treatment response compared with psoriasis. Most reports are case based without controls, so more studies are needed to further prove the causality. However, early recognition of factors causing or aggravating PsA is important to prevent the irreversible joint damage.

Management Strategies for Pediatric Moderate-to-Severe Plaque Psoriasis: Spotlight on Biologics

Although psoriasis onset has been reported at any ages, in up to one-third of cases, it begins during childhood, with an estimated prevalence of about 2% in pediatric population. The management of moderate-to-severe forms of childhood psoriasis may represent a challenge for dermatologists, especially for parents' concerns about the need of systemic treatments. However, a prompt safe and effective treatment is mandatory in these patients, due to the significative impact that psoriasis may have on their quality of life, with well-known consequences on psychological health of both patients and caregivers. Due to the relatively frequent parents' refusal of systemic treatments, probably due to the fear of eventual adverse events, difficulties of oral or injective route, the management of moderate-to-severe forms still represents a challenge. Herein, we report a narrative review, aiming to resume the systemic treatments for pediatric psoriasis, focusing on the use of biologics and small molecules in the pediatric ages. The most widely used therapeutic strategies today for the pediatric population with moderate-severe psoriasis are traditional systemic therapies, while more innovative drugs such as biologics and small molecules now represent a somewhat unexplored but certainly promising field for unresponsive patients.

JAK Inhibitors in Psoriatic Disease

Psoriasis is now considered to be the cutaneous phenotype of a systemic inflammatory condition, recognized under the term Psoriatic Disease (PsD). PsD has several extracutaneous manifestations, such as inflammatory articular and entheseal involvement, leading to psoriatic arthritis (PsA), and the less frequent intestinal and ocular manifestations with colitis/inflammatory bowel disease and uveitis, respectively. There have also been several reports of an increased frequency of comorbidities such as hypertension, diabetes, dyslipidemia, obesity, metabolic syndrome and cardiovascular manifestations during the course of PsD. The link between psoriasis and related comorbidities is considered a long-term disease sequela, often characterized by an unhealthy lifestyle and a consequence of systemic inflammation; hence, psoriasis requires adequate and prompt treatment, with the aim of controlling not only cutaneous manifestations but also extracutaneous manifestations and systemic inflammation. Pharmacological strategies for PsD have significantly increased over recent years. Recently, the targeted synthetic DMARDs, Janus kinase (JAK) inhibitors, tofacitinib and upadacitinib, were added to the therapeutic armamentarium for treating PsA, and deucravacitinib for psoriasis. These oral agents act directly on inflammatory mechanisms underlining the disease, as antagonists of the intracellular JAK signal pathway and, by STAT phosphorylation, inhibit gene proinflammatory cytokine transcription. JAK inhibitors represent a recent additional treatment strategy for PsD management and, among these, tofacitinib and upadacitinib have recently been approved for PsA, and deucravacitinib for psoriasis. In this review we describe ongoing and recent phase II and III randomized controlled trials (RCTs) evaluating the efficacy and safety of investigational JAK inhibitors in psoriasis and PsA.

Effectiveness of Brodalumab in Patients with Moderate-to-Severe Plaque Psoriasis Located in Difficult-to-Treat Areas

Background

Recent knowledge of psoriasis pathogenesis has led to the development of selective drugs. Among these, brodalumab is a monoclonal antibody targeting the interleukin (IL)-17A receptor approved for the treatment of moderate-to-severe plaque psoriasis. Biologics may be considered in patients with milder diseases in case of active psoriatic arthritis, severe impact on patient's quality of life, and involvement of sensitive and difficult-to-treat areas. These skin locations commonly require systemic drugs. Recently, psoriasis severity monitoring has also changed. Indeed, the clinical evaluation by means of specific efficacy scores was combined with serological evaluation by means of the assay of specific inflammatory biomarkers.

Methods

An observational study enrolled patients affected by moderate-to-severe plaque psoriasis involving difficult-to-treat areas, undergoing treatment with brodalumab to evaluate the effectiveness and safety of brodalumab in patients with psoriasis affecting difficult-to-treat areas (scalp and palmoplantar regions). Secondary outcomes were the assessment of the development of serum markers of inflammation during the treatment period as well as the evaluation of the dermoscopic features of the affected sites to quantify disease activity and response to treatment.

Results

Twenty-five patients were included in the study. A statistically significant reduction from baseline in PASI, PSSI, ppPASI and DLQI values as early as week 24 was observed, with further improvement up to week 52. Plasma levels of MMP-3, VEGF-A, and hs-PCR decreased during treatment from week 0 to week 52.

Conclusion

Our real-life experience suggests brodalumab as a valuable option for the management of psoriasis located in difficult-to-treat areas. Moreover, our study highlights that the use of brodalumab reduces the plasmatic levels of inflammatory biomarkers (MMP-3, VEGF-A and hs-PCR), showing how the drug modulates the skin inflammatory response by reducing systemic inflammation.

Biologics for the Management of Erythrodermic Psoriasis: An Updated Review

Erythrodermic psoriasis (EP) is a severe and rare variant of psoriasis (less than 3% of cases), characterized by generalized scaling and erythema affecting more than 90% of body surface area. Several systemic symptoms can be present in patients with EP such as lymphadenopathy, arthralgia, fever, fatigue, dehydration, serum electrolyte disturbances, and tachycardia making this condition a possible life-threatening disease, particularly if appropriate treatments are not performed. In this scenario, effective and safe therapies are required. Unfortunately, the rarity of EP makes head-to-head Phase III trials challenging, leading to the lack of established guidelines for its management. Globally, conventional systemic drugs such as cyclosporine, methotrexate, and retinoids often have contraindications linked to patients' comorbidities and have not shown a high profile of efficacy and safety. Recently, the development of biologic drugs including anti-tumor necrosis factor-α and anti-interleukin 12-23, 23, and 17 has revealed favorable results for the management of plaque psoriasis, making them also a possible therapeutic option for EP disease. However, their use in EP is still off-label. The aim of our study was to review current literature on the use of biologic drugs for the treatment of EPs in order to offer a wide perspective on their possible application in EP management.

New Onset and Exacerbation of Psoriasis Following COVID-19 Vaccination: A Review of the Current Knowledge

COVID-19 vaccination was the main measure to overcome the pandemic. As with other drugs and vaccines, mild to moderate adverse events have been reported following vaccination. In addition, several cutaneous reactions have been described. In particular, there are several reports investigating de novo psoriasis or the exacerbation of psoriasis following COVID-19 vaccination. However, data on the possible pathogenetic mechanisms as well as comprehensive manuscripts on the topic are scant. Thus, the aim of our manuscript was to perform a review of the current literature on post-COVID-19 vaccination exacerbations and new-onset psoriasis in order to offer a wide perspective on this area and to point out possible pathogenetic mechanisms. Research on the current literature was performed following PRISMA guidelines. In total, 49 studies involving 134 patients developing new-onset psoriasis (n = 27, 20.1%) or psoriasis exacerbation (n = 107, 79.9%) were collected. Although cases of de novo psoriasis or a worsening of psoriasis have been reported following vaccination, all of the cases have been successfully treated while overall benefit-risk profile of COVID-19 vaccination does not justify vaccine hesitancy due to the risk of psoriasis being developed or worsening. Certainly, further studies are needed to identify possible pathogenetic mechanisms in order to identify "at-risk" patients. Finally, vaccination should not be discouraged.

Efficacy and safety of spesolimab for the management of generalized pustular psoriasis: a drug safety evaluation

INTRODUCTION

Generalized pustular psoriasis (GPP) is a rare form of psoriasis (less of 1% of cases). Currently, GPP is recognized as a clinical entity, distinguished from plaque psoriasis. However, there are not guidelines for GPP management and treatments are often derived from plaque psoriasis. Therefore, conventional systemic drugs are usually used as first-line treatment options, and biologics are still used off label. Recently, spesolimab, an anti-IL36 receptor humanized IgG1 monoclonal antibody, has been specifically approved for GPP disease, revolutionizing treatment scenario.

AREAS COVERED

The aim of this review is to investigate current literature on the use of spesolimab for GPP management to underline its potential role in GPP and offer a current clinical perspective. Literature research using the Google Scholar, Pubmed, Embase, Cochrane Skin, and clinicaltrials.gov databases was performed, selecting the most relevant manuscripts.

EXPERT OPINION

Spesolimab is efficacious and has a consistent and favorable safety profile in patients presenting with a GPP flare. However, despite excellent results in terms of safety and efficacy have been reported by both clinical trials and very limited real-life experiences, long-term data, especially in flare-up prevention, are scant. Thus, while the available data are encouraging, further research is warranted to understand the efficacy, safety, and long-term outcomes associated with spesolimab treatment in GPP.

Use of Biological Therapies for the Management of Pustular Psoriasis: A New Era?

Generalized pustular psoriasis (GPP) is a severe and rare form of psoriasis, being a potentially life-threatening condition, characterized by recurring episodes or flares of widespread cutaneous erythema with macroscopic sterile pustules. An irregular innate immune response is linked to GPP, which is considered an auto-inflammatory disorder, while innate and adaptive immunopathogenic responses are involved in psoriasis pathogenesis. In consequence, different cytokine cascades have been suggested to be mainly involved in the pathogenesis of each different psoriasis form, with the interleukin (IL)23/IL17 axis implied in plaque psoriasis, and the IL36 pathway in the GPP. As regards GPP treatment, conventional systemic drugs available for plaque psoriasis are usually used as the first-line treatment option. However, contraindications and adverse events often limit the use of these therapies. In this scenario, biologic drugs may represent a promising treatment option. To date, even if 12 different biologics have been approved for plaque psoriasis, none of these is approved for GPP where they are employed off-label. Recently, spesolimab, an anti-IL36 receptor monoclonal antibody, has been recently approved for GPP. The purpose of this article is to assess the current literature about the use of biological therapies for the treatment of GPP to establish the basis for a shared GPP management algorithm.

The Impact of COVID-19 Vaccination on Inflammatory Skin Disorders and Other Cutaneous Diseases: A Review of the Published Literature

Background: Four vaccines have been authorized by the European Medicines Agency (EMA): viral vector-based vaccines (AstraZeneca; AZD1222 and Johnson & Johnson; Ad26.COV2. and 2 mRNA-based vaccines (Pfizer/BioNTech; BNT162b2 and Moderna; mRNA-1273). Adverse events (AEs) related to vaccination have been described in the literature. The main aim of the dermatological practice was to avoid the diffusion of COVID-19, allowing the continuity of care for patients. Objective: The aim of this review article is to investigate current literature regarding cutaneous reactions following COVID-19 vaccination, mainly inflammatory dermatological diseases. Materials and methods: Investigated manuscripts included metanalyses, reviews, letters to the editor, real-life studies, case series, and reports. Results: We selected a total of 234 articles involving more than 550 patients. We have divided the results section into various sub-sections to ensure greater understanding for readers. Conclusions: Clinicians should keep in mind the possibility of new onsets or the worsening of several dermatoses following vaccination in order to promptly recognize and treat these AEs. Certainly, vaccination should not be discouraged.

Long-Term Efficacy and Safety of Risankizumab for Moderate to Severe Psoriasis: A 2-Year Real-Life Retrospective Study

Risankizumab is a humanized IgG monoclonal antibody inhibitor of IL23 and has been recently approved by the EMA and the FDA for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy. Its efficacy and safety have been reported by clinical trials and real-life studies. However, even if long-term data from trials have already been reported (up to 172 weeks), data on long-term real-life experiences are still limited. The aim of our study was to investigate the long-term (2 years) efficacy and safety of risankizumab for psoriasis management in a real-life setting. A monocentric retrospective study was performed, enrolling 168 patients affected by moderate to severe psoriasis who were undergoing treatment with risankizumab. Psoriasis severity and safety outcomes were evaluated at each follow-up visit (week 16, week 28, week 52, week 88, week 104). A statistically significant reduction of psoriasis severity scores was reported from week 16 and was maintained up to week 104. Moreover, interesting results in terms of safety have been collected, without any serious adverse events registered. Our long-term real-life monocentric retrospective study confirmed the efficacy and safety of risankizumab up to 104 weeks of treatment. However, further studies are required to confirm our results and to increase available data to establish the best evidence-based biologic selection algorithm.

Efficacy and safety of biologics and small molecules for psoriasis in pediatric and geriatric populations. Part I: focus on pediatric patients

INTRODUCTION

Psoriasis management is challenging, especially in pediatric age for different factors. The introduction of biologic drugs and oral small molecules (OSM) revolutionized the armamentarium of available weapons in psoriasis treatment. Despite the use of these drugs in adult patients has been widely investigated, pediatric patients have often been unconsidered in clinical trials and real-life studies. However, the high efficacy and speed of action, the safety profile and the ease-to-use administration make these innovative drugs an invaluable therapeutic opportunity.

AREAS COVERED

The aim of this manuscript is to perform a review of the current literature examining data on the effectiveness and safety of biologic drugs and OSM for the management of psoriasis in pediatric patients in order to put the basis for universally shared treatment algorithm following available evidence. PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines were used for the literature research.

EXPERT OPINION/COMMENTARY

Our review based on currently available evidence suggests biologics and OSM as an ideal treatment option for pediatric patients, with an excellent profile in terms of efficacy and safety as compared to traditional systemic drugs.

Bimekizumab treatment in patients with moderate to severe plaque psoriasis: a drug safety evaluation

INTRODUCTION

Biological treatments deeply changed the management of moderate-to-severe forms of psoriasis. Among the available biological therapies, interleukin (IL)-17 inhibitors, secukinumab, ixekizumab, brodalumab, and bimekizumab represent one of the most rapid and effective biologic classes available for psoriasis. Bimekizumab, the latest available IL-17 inhibitor, is a humanized monoclonal immunoglobulin (Ig)G1 antibody that acts by neutralizing both IL-17A and IL-17F, showing a unique mechanism of action differing from ixekizumab and secukinumab (selective IL17A inhibitor), as well as brodalumab (antagonist of IL17 receptor).

AREAS COVERED

This review aims to evaluate the safety profile of bimekizumab in the treatment of moderate-to-severe plaque psoriasis.

EXPERT OPINION

The efficacy and safety of bimekizumab have been reported by several phase II and III clinical trials, even in a longer-term period. Moreover, clinical trials also showed bimekizumab to have significantly higher efficacy compared to other biological classes, including anti-TNF, anti-IL-12/23, and even to another IL-17 inhibitor, secukinumab. Although numerous biologics are currently available for psoriasis, some patients may result resistant to other treatments and/or experience psoriatic flares during or after treatment withdrawal. In this scenario, bimekizumab may represent an additional valuable alternative for patients with moderate-to-severe forms of psoriasis.

Safety and Efficacy of Covid-19 Vaccination in Patients Undergoing Biological Treatments for Psoriasis

The introduction of biologic drugs revolutionized the treatment of psoriasis, shifting treatment goals to higher treatment outcomes and less frequent safety issues. The outbreak of Coronavirus disease 2019 (COVID-19) represented a worldwide challenge, strongly affecting lifestyle, global economy, and overall health. Among the strategies adopted to contain the spreading of the infection, vaccination is the main one. In this context, the introduction of COVID-19 vaccines raised several doubts about their effectiveness and safety in patients undergoing therapy with biological for psoriasis. Even if molecular and cellular mechanisms by which COVID-19 vaccines lead to psoriasis development have not yet been fully elucidated, vaccination itself can trigger the release of interleukin (IL)-6, interferon (IFN) and tumor necrosis factor (TNF) α by T-helper (Th)1/Th17 cells. All these cytokines are involved in psoriasis pathogenesis. Thus, the aim of this manuscript is to review current literature on the safety and effectiveness of COVID-19 vaccination in psoriasis patients undergoing treatment with biologics, in order to clarify any concerns.

Injections Site Reactions and Biologics for Psoriasis: A Questionnaire Based Real Life Study

Background

Biologic selection for psoriasis treatment should take into account numerous factors including injection site reactions (ISRs) such as swelling at the injection site, pain, burning, erythema, all possibly reducing patient adherence.

Methods

A 6-months observational real life study was performed involving psoriasis patients. Inclusion criteria were age ≥ 18 years, moderate-to-severe psoriasis diagnosis since at least 1 year, patients being on biologic treatment for psoriasis ≥ 6 months. A 14-item questionnaire was administered to all patients enrolled to assess whether the patient ever experienced ISRs after the injection of the biologic drug.

Results

234 patients were included: 32.5% received an anti-TNF-alpha drug, 9.4% received anti-IL12/23, 32.5% received an anti-IL17, 25.6% received an anti-IL23. 51.2% of study population reported at least one symptom related to ISR. 35.9% of patients experienced pain, 31.6% swelling, 28.2% burning sensation and 17.9% erythema. 3.4% of the surveyed population experienced anxiety or fear of the biologic injection due to ISRs symptoms. The greater incidence of pain was registered in anti-TNF-alpha and anti-IL17 groups (47.4% and 42.1%, p<0.01). Ixekizumab proved to be the drug with the highest rate of patients experiencing pain (72.2%), burning (77.7%) and swelling (83.3%). No patients reported biologics discontinuation or delay for ISRs symptoms.

Conclusion

Our study highlighted that each different class of biologics for psoriasis was linked to ISRs. These events are more frequently reported with anti-TNF-alpha and anti-IL17.

The Role of Teledermatology During the COVID-19 Pandemic: A Narrative Review

Teledermatology represented one of the most important and useful tools during the COVID-19 pandemic era. Indeed, due to the severe restriction, and to reduce the spread of the infection, different measures were applied among different countries and hospitals to ensure a continuity of care for patients. In this scenario, teledermatology played a central role, especially in the management of patients suffering from chronic inflammatory skin diseases. The aim of this narrative review is to describe the role of teledermatology during the COVID-19 pandemic to analyze main strengths and limitations of this tool, as well as to provide future perspectives in clinical applications.

Drug safety evaluation of tildrakizumab for psoriasis: a review of the current knowledge

INTRODUCTION

Psoriasis is a chronic inflammatory skin disease that may have an important negative impact on a patient's quality of life. Biological agents deeply changed the management of its moderate-to-severe forms. Interleukin-23 inhibitors represent the latest biologics class approved for the treatment of moderate-to-severe psoriasis. In particular, tildrakizumab, the latest available anti-interleukin-23 on the Italian market, is a humanized monoclonal antibody specifically targeting the p19 subunit of IL-23.

AREAS COVERED

The objective of this review is to evaluate the safety profile of tildrakizumab in moderate-to-severe psoriasis patients. A literature review included articles until July 2022.

EXPERT OPINION

Our analysis showed tildrakizumab as a generally safe option for the treatment of psoriasis, with most of the reported adverse events being classified as mild or moderate, and rarely requiring treatment discontinuation. Furthermore, in line with other interleukin-23 inhibitor, no concerns have been raised for tildrakizumab in regard to inflammatory bowel diseases, which represent a significant comorbidity to investigate before starting other biologics (IL-17 inhibitors). However, more real-life long-term data are needed to confirm trial results to further confirm tildrakizumab as a generally safe treatment option for psoriasis.

Psoriasis and medical ramifications: A comprehensive analysis based on observational meta-analyses

Purpose

Based on a large number of systematic reviews and meta-analyses exploring the relationship between psoriasis and various health outcomes, we conducted an comprehensive analysis to assess the strength and evidence for the association between psoriasis and medical end-point ramifications in patients.

Methods

We searched related meta-analyses, investigating the links between psoriasis and medical ramifications from three databases. All summary effect sizes, 95% CIs, heterogeneity, and small-study effects in the included meta-analyses were recalculated. We assessed the methodological quality of included articles with the AMSTAR 2 tool and graded the epidemiological evidence. Subgroup analysis based on the severity of psoriasis and study design were also performed.

Results

A total of 38 articles comprising 85 unique meta-analyses were included in this study. Although 69 outcomes were statistically significant, only 8 outcomes (nonvascular dementia, ulcerative colitis, pediatric dyslipidemia, gestational diabetes, gestational hypertension, fracture, multiple sclerosis, and schizophrenia) showed a high quality of epidemiological evidence.

Conclusion

We found that psoriasis increased the risk of 69 health outcomes, and 8 outcomes were graded as high-quality evidence. No evidence was found that psoriasis was beneficial for any medical end point. However, to verify our results, more large-sample, multi-center prospective cohort studies are needed.

Real-world clinical outcomes of treatment with brodalumab in patients with moderate-to-severe psoriasis: a retrospective, 24-month experience from four academic dermatology centers in Greece

OBJECTIVE

To assess the real-world clinical treatment outcomes with brodalumab in patients with moderate-to-severe plaque psoriasis in Greece.

MATERIALS AND METHODS

This was a longitudinal, retrospective, real-world analysis of data from medical records of 106 patients with moderate-to-severe plaque psoriasis, treated with brodalumab for up to 24 months at four University Dermatology Centers in Greece. Efficacy assessments of psoriasis severity [Psoriasis Area and Severity Index (PASI) and Body Surface Area affected (BSA) scores] and its impact on patients' quality of life (QoL) [Dermatology Life Quality Index (DLQI) score] were evaluated at different timepoints up to 24 months.

RESULTS

Treatment with brodalumab reduced both mean PASI (14.0-1.5, p < .001) and BSA scores (21.6-2.5, p < .001) across all visits. This effect was accompanied by reduction in mean DLQI score (12.8-2.1, p < .001) across all visits compared with baseline. Moreover, therapeutic efficacy was affected by prior biologic treatment exposure, as biologic naïve patients had greater reductions in all scores from baseline following treatment with brodalumab (numerical for mean PASI, significant for mean BSA and DLQI scores).

CONCLUSION

Brodalumab is effective long term, improving disease severity and health-related QoL in patients with moderate-to-severe plaque psoriasis in a real-world setting.

Long-Term Efficacy and Safety of Guselkumab for Moderate to Severe Psoriasis: A 3-Year Real-Life Retrospective Study

Introduction

Guselkumab safety and efficacy profiles in psoriasis have been showed by VOYAGE (1 and 2) trials. Although trial results have been already previously confirmed by real-life studies, long-term real-life data, and drug survival data about guselkumab are still poor.

Patients and Methods

We performed a 3-year retrospective study, with the aim of assessing guselkumab efficacy and safety profile in the management of plaque psoriasis in a real-life setting.

Results

Thirty-one patients completed the study. Both Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA) statistically improved since week 16, and up to week 144 [PASI reduction from 16.4 ± 6.2 to 0.6 ± 0.9 (p < 0.0001) at week 144 while BSA from 33.2 ± 14.6 to 1.9 ± 1.4 (p < 0.0001)]. At week 12 PASI90 and PASI100 were achieved by 19 (61.3%) and 11 (35.4%) patients, respectively, as well as 24 (77.4%) and 18 (58.1%) subjects reached PASI 90 and PASI 100 at week 144. As regards the safety, no cases of injection site reaction, candida, serious AEs, malignancy, or major cardiovascular events were reported. Of note, mild AEs were collected with pharyngitis as the main one (7, 22.6%), followed by headache (5, 16.1%) and flu-like illness (5, 16.1%), all without requiring treatment discontinuation.

Conclusion

Our experience confirmed the efficacy and safety of guselkumab in daily clinical practice up to 3 years, suggesting this drug as an effective treatment option in psoriasis long-term management.

Ixekizumab and brodalumab indirect comparison in the treatment of moderate to severe psoriasis: results from an Italian single-centre retrospective study in a real-life setting

BACKGROUND

Eleven biologic drugs are currently approved for psoriasis management. Real-life studies are needed to guide clinicians in choosing a tailored-tail therapy. The aim of our retrospective study is to indirectly compare the efficacy and safety of ixekizumab and brodalumab in psoriasis patients.

METHODS

A single-centre real-life retrospective study was performed enrolling moderate-to-severe psoriatic patients under biologic treatment with ixekizumab or brodalumab. For each patient, clinical and demographic data were collected and the effectiveness and safety of brodalumab and ixekizumab treatment were evaluated at weeks 4, 12 and 24. Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA) were used for psoriasis severity.

RESULTS

A total of 139 patients were included in the study: 98(70.5%) and 41(29.5%) patients received ixekizumab and brodalumab, respectively. Mean PASI and BSA significantly reduced at each follow up for both ixekizumab and brodalumab groups. Even if ixekizumab reached higher rates of PASI90 and PASI100 than brodalumab (PASI90: 43.8%vs39.0% PASI100: 20.4%vs17.1% at week4 and PASI90: 83.6%vs75.6% PASI100: 71.5%vs60.9% at week24), these results were not statistically significant. Adverse events, mainly mild, were registered in 25.5% of ixekizumab and 26.8% of brodalumab group, respectively. Discontinuation rate was higher for brodalumab (17.1%vs9.1%), without statistical significance.

CONCLUSION

Our study showed comparable efficacy and safety for ixekizumab and brodalumab.

Bimekizumab for the Treatment of Psoriasis: A Review of the Current Knowledge

Bimekizumab, a novel humanized monoclonal IgG1 antibody that neutralizes both IL-17A and IL-17F, was recently approved the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy. Bimekizumab represents the latest anti IL-17 treatment available for the management of moderate to severe psoriasis. Bimekizumab safety and efficacy profiles were evaluated in four Phase III clinical trials, which evaluated bimekizumab versus placebo and ustekinumab (BE VIVID), versus placebo (BE READY), versus adalimumab (BE SURE), and versus secukinumab (BE RADIANT). Overall, bimekizumab displayed promising results in terms of both efficacy and safety, allowing reach PASI90 and PASI100 in short time (as early as week 4) and maintain it in the long term (52 weeks), with acceptable safety profile. Also, bimekizumab showed a rapid onset of response and a higher efficacy when compared to adalimumab, ustekinumab and secukinumab, with comparable safety profile. Herein, we carried out a comprehensive literature review of the available literature data about bimekizumab in the treatment of moderate to severe psoriasis.

Risankizumab treatment in psoriasis patients who failed anti-IL17: a 52-week real-life study

Recent knowledge on the key role of interleukin (IL) 23/17 axis in psoriasis pathogenesis, led to development of new biologic drugs. Risankizumab is a humanized immunoglobulin G1 monoclonal antibody specifically targeting IL23. Its efficacy and safety were showed by both clinical trials and real‐life experiences. However, real‐life data on effectiveness and safety of risankizumab in patients who previously failed anti‐IL17 are scant. To assess the efficacy and safety of risankizumab in patients who previously failed anti‐IL17. A 52‐week real‐life retrospective study was performed to assess the long‐term efficacy and safety of risankizumab in patients who previously failed anti‐IL17. A total of 39 patients (26 male, 66.7%; mean age 50.5 ± 13.7 years) were enrolled. A statistically significant reduction of psoriasis area severity index (PASI) and body surface area (BSA) was assessed at each follow‐up (PASI at baseline vs. week 52: 13.7 ± 5.8 vs. 0.9 ± 0.8, p < 0.0001; BSA 21.9 ± 14.6 vs. 1.9 ± 1.7, p < 0.0001). Nail psoriasis severity index improved as well, being statistically significative only at week 16 and thereafter [9.3 ± 4.7 at baseline, 4.1 ± 2.4 (p < 0.01) at week 16, 1.4 ± 0.8 (p < 0.0001) at week 52]. Treatment was discontinued for primary and secondary inefficacy in 1(2.6%) and 3(7.7%) patients, respectively. No cases of serious adverse events were assessed. Our real‐life study confirmed the efficacy and safety of risankizumab, suggesting it as a valuable therapeutic weapon among the armamentarium of biologics, also in psoriasis patients who previously failed anti‐IL17 treatments.

Beneficial effects of Rocchetta® oligomineral water in HaCaT keratinocytes after ultraviolet-B irradiation

BACKGROUND

Several reports have previously suggested that oligomineral water may have a beneficial immunomodulatory role in skin physiology. However, molecular, and cellular mechanisms through which oligo-elements act in cutaneous trophism have not yet been fully clarified. Among the external stimuli that affect the skin, ultraviolet (UV) radiation, which is frequently encountered in everyday life, is a major environmental factor of skin damage. Keratinocytes are the major target of UV, and they play a key role in a first line of body defenses. Accumulating evidence suggests that UVB irradiation induces nuclear DNA damage, membrane destruction, resulting in apoptosis and skin inflammation. The aim of this study was to investigate the anti-inflammatory, antioxidant, antiapoptotic effects of Rocchetta® oligomineral (Co.Ge.Di. International SpA, Rome, Italy) water in UVB-irradiated immortalized human keratinocytes.

METHODS

HaCaT UVB-irradiated was cultured with increasing concentrations of Rocchetta® oligomineral water. To evaluate the anti-inflammatory properties gene expression of TNF, IL1β, IL6, COX2 and Caspase1 was performed. Moreover, the antiapoptotic effects were evaluated through gene expression of GADD45, Caspase3 and RIPK3. Finally, we evaluated the antioxidant activity of Rocchetta® oligomineral water by measuring total ROS/RNS and superoxide production as markers of oxidative stress after UVB irradiation.

RESULTS

Our findings have shown that Rocchetta® oligomineral water is well tolerated by the cells and displays anti-inflammatory, antioxidant and antiapoptotic proprieties when used prior keratinocyte UVB irradiation.

CONCLUSIONS

Our results highlight a possible protective role of Rocchetta oligomineral water in modulating the cutaneous inflammatory response to external triggers and injuries.

Guselkumab is efficacious and safe in psoriasis patients who failed anti-IL17: a 52-week real-life study

BACKGROUND

Interleukin (IL)23/Th17 axis is the leading actor of psoriasis pathogenesis. Guselkumab is the first anti-IL23 approved for psoriasis. Anti-IL23 and anti-IL17 partially share their therapeutic target currently appearing as the most efficacious available psoriasis treatments. Real-life data on guselkumab performance in anti-IL17 failure patients are scant.

METHODS

A 52-week real-life single-center retrospective study was performed to evaluate the long-term efficacy and safety of guselkumab in patients who previously failed anti-IL17.

RESULTS

A total of 44 patients were enrolled (28 male, 63.6%; mean age 59.0 ± 10.2years). A statistically significant improvement of Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA) was assessed at each follow-up (PASI decreased from 13.9 ± 8.1 to 0.9 ± 0.7 at week52 while BSA from 24.3 ± 19.6 to 1.3 ± 1.4, p < 0.001). Nail Psoriasis Severity Index (NAPSI) improvement was collected as well, even if being statistically significative only at week28 and thereafter [2.9 ± 6.2 at baseline, 0.9 ± 1.5 at week28, (p < 0.05)]. Only 3(6.8%) patients discontinued guselkumab due to secondary inefficacy. No cases of serious Adverse Events were assessed.

CONCLUSION

Our real-life study confirmed the efficacy and safety of guselkumab in daily clinical practice suggesting it as a valuable weapon also in psoriasis patients who previously failed anti-IL17 treatments.
