Ocular Manifestations in Psoriasis Screening (OcMaPS) Questionnaire: A Useful Tool to Reveal Misdiagnosed Ocular Involvement in Psoriasis

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.

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.

Anti-IL23 biologic therapies in the treatment of psoriasis: real-world experience versus clinical trials data

Nowadays, the biological equipment available for the treatment of moderate-to-severe psoriasis is plenty. Anti-interleukin-23 represents the latest class of biologic approved for the management of moderate-to-severe psoriasis. Their efficacy and safety have been assessed through two major sources: clinical trials (CTs) and real-world experiences data (RWE). Notably, the two sources differ from one another, but together, they complement information and current knowledge on both efficacy and safety of biological therapy. We carry out a review on CTs and RWE reports on the latest group of biological approved for moderate-to-severe psoriasis: anti-IL23 (guselkumab, risankizumab, and tildrakizumab).

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.

Psoriasis complicated with metabolic disorder is associated with traditional Chinese medicine syndrome types: a hospital-based retrospective case-control study

OBJECTIVE

To explore the distribution law of traditional Chinese medicine (TCM) syndrome types in patients with psoriasis vulgaris complicated by metabolic disorders based on the same pathogenic factors as blood-heat and blood-stasis in the pathogenesis of psoriasis and metabolic disorders and to further analyze the correlation between adiponectin and the distribution law.

METHODS

From 1 January 2018 to 31 December 2019, patients diagnosed with psoriasis in the inpatient or outpatient department of Dermatology Ward of Shanghai Yueyang Hospital and normal participants who underwent physical examination in the physical examination center over the same period were retrospectively reviewed. Demographic data, medical history, metabolic disorder indices, and TCM syndrome indices of psoriasis patients and healthy volunteers were evaluated.

RESULTS

We included 307 patients with psoriasis and 613 healthy controls. On analyzing past medical history, the proportion of overweight and obesity and the comorbidity of diabetes in the psoriasis group (53.42 and 14.66%) were significantly higher than in the control group (43.88 and 7.67%, respectively; p < .05). The abnormal rates of triglyceride (34.20%), high-density lipoprotein cholesterol (50.49%), and HbA1c (18.57%) levels in the psoriasis group were higher than those in the normal control group (26.75, 17.13, and 12.56%, respectively). Overall, the incidence of metabolic disorders in psoriasis patients (267/307, 86.97%) was higher than that in the normal controls (484/613, 78.96%). Among the different syndrome types, the blood-stasis group had significantly higher rates of hypertension, diabetes, and abnormal glycosylated hemoglobin (46.07, 19.10, and 24.72%, respectively) than those of the control group (27.57, 7.67, and 12.56%; p < .05). Patients with blood stasis syndrome had the highest metabolic disorder comorbidity rate (93.26%) and lowest adiponectin level (p < .05).

CONCLUSIONS

TCM syndrome differentiation of psoriasis, especially the diagnosis of blood-stasis syndrome, prompts the early screening of patients with metabolic comorbidities. For patients with psoriasis with metabolic disorder, TCM for promoting blood circulation and removing blood stasis can be compatibly applied without contraindications.

TRIAL REGISTRATION

The trial was registered at ClinicalTrials.gov (Trial ID: NCT03942185).

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.

Economic Burden of Comorbidities in Patients with Psoriasis in the USA

INTRODUCTION

This study assessed the comorbidity burden, healthcare resource utilization (HCRU), and costs associated with patients with moderate to severe psoriasis (PsO) compared with a matched cohort of the general population without PsO in the USA.

METHODS

Comorbidity-related HCRU (incidence rate ratios [IRRs]) and direct medical cost burden (per patient per month [PPPM] 2020 USD) in patients with moderate to severe PsO in the USA, previously apremilast- and biologic-naive, but currently treated, versus the general population were assessed through a retrospective cohort study using IBM (now Merative) MarketScan Commercial and Medicare Claims data (1 January 2006 to 31 December 2019). Comorbidities included cardiovascular, mental health, pulmonary, diabetes, hyperlipidemia, hypertension, peripheral vascular, liver, obesity, and other autoimmune disorders.

RESULTS

There are increased all-cause HCRU and costs in patients with PsO compared with the general population. These differences (PsO-general population) in HCRU and costs (IRR visits; PPPM) are associated with specific comorbidities, including mental health (1.08; $372), chronic pulmonary disease (1.07; $135), diabetes (1.10; $159), hyperlipidemia (1.13; $203), hypertension (1.13; $305), liver disease (1.21; $360), and obesity (1.12; $145, all P < 0.01).

CONCLUSIONS

Patients with PsO experience a higher economic burden of comorbidities than the general population despite using currently available systemic treatments for PsO.

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

INTRODUCTION

Since Anti-IL-17s availability, concerns about their safety have been raised due to the inhibition of physiological activities that IL-17A plays in the immune response against infections. Ixekizumab is a humanized monoclonal antibody specifically targeting IL-17A approved for the treatment of moderate-to-severe psoriasis.

AREAS COVERED

The aim of this review is to evaluate the safety profile of ixekizumab in moderate to severe psoriasis patients. A compressive literature review included article since March 2022.

EXPERT OPINION

in our analysis, most of the reported AEs were mild or moderate and rarely required treatment discontinuation. Among the class specific AEs to consider during ixekizumab treatment, there are the risk of Candida spp infections and the risk of IBD, which both were reported more frequently than if compared with placebo or other biologics (etanercept, ustekinumab, guselkumab). However, the reported candidiasis resulted mild-to moderate, and easily managed. The risk of IBD (both exacerbation and de novo diagnosis) represents a class effect of IL-17 inhibitors, which should be well evaluated before considering starting ixekizumab treatment. the most common AEs were represented by nasopharyngitis, upper respiratory tract infection, and injection-site reactions. The analysed studies confirmed the favourable safety profile of ixekizumab even in more recently published studies.

The Potential Role of Serum Tau Protein (MAPT), Neuronal Cell Adhesion Molecule (NrCAM) and Neprilysin (NEP) in Neurodegenerative Disorders Development in Psoriasis-Preliminary Results

Psoriasis is one of the most common dermatoses, which shortens patients’ lives because of the wide comorbidity. However, little is known about its association with neurodegenerative diseases (NDs). We aimed to investigate whether psoriatics are at increased risk of NDs. Sixty patients with plaque-type psoriasis were enrolled into the study. Serum concentrations of tau protein (MAPT), neuronal cell adhesion molecule (NrCAM) and neprilysin (NEP), which are NDs biomarkers and have been hardly studied in psoriasis before, were measured before and after 12 weeks of treatment with acitretin or methotrexate. NrCAM and NEP concentrations were significantly lower in patients than controls, whereas MAPT higher (all p < 0.05). There was no association between these markers and psoriasis severity, BMI or disease duration. After the treatment the concentration of NrCAM and NEP significantly increased and MAPT decreased (p < 0.001, p < 0.05, p < 0.01, respectively). Methotrexate had significant influence on the concentrations of all markers, hence it seems to have neuroprotective properties. Psoriasis severity and duration do not seem to affect the risk of neurodegenerative process. Our results suggest that NDs could be considered as another comorbidity of psoriasis and that further research are needed in order to establish their definite association.

Ocular manifestations of psoriasis: An inflammatory disease beyond the skin

Background

Psoriasis is a chronic inflammatory disorder, mainly involves skin.

Aims

To evaluate the prevalence of ocular manifestations in Iranian patients with psoriasis, compared to healthy controls.

Materials and methods

Forty psoriasis patients and 40 age- and gender-matched healthy controls were enrolled in the study and underwent a comprehensive ophthalmologic assessment.

Results

Only meibomian gland dysfunction was significantly more common among patients with psoriasis, compared to control group (p value: 0.011). Regarding intraocular pressure (IOP), the mean values for both patients and healthy controls were within the normal range and mean IOP in patients was even lower than normal controls, although this difference was significant only for left eye (p value: 0.049). A strong positive correlation between PASI and tear meniscus height for both right and left eyes (p value: 0.005, r: 0.44 for OD and p value: 0.003, r: 0.46 for OS.) was noted. Meibomian gland dysfunction was also positively correlated with disease duration for right and left palpebras (p: 0.04, r: 0.31 for both).

Conclusion

Psoriasis can lead to meibomian gland dysfunction, especially in patients with long-lasting disease. Hence, dermatologists and general practitioners should be vigilant in this regard when visiting psoriasis patients, especially those who have higher PASI values or long-lasting disease.

Guselkumab, Risankizumab, and Tildrakizumab in the Management of Psoriasis: A Review of the Real-World Evidence

Interleukin (IL)-23 inhibitors, guselkumab, risankizumab, and tildrakizumab, represent the latest class of biologics approved for the treatment of moderate-to-severe psoriasis. Since their approval numerous real-life studies were published on anti-IL-23 use in routine clinical practice. Indeed, real-life data are important to improve the dermatological decision-making process, including patients who are typically excluded from clinical trials, such as subjects suffering from several comorbidities, subjects on polypharmacy, as well as multifailure patients. Herein, we performed a comprehensive literature review about real-life data available on guselkumab, risankizumab, and tildrakizumab. Real-life data of anti-IL-23 seem to confirm the promising results of IL-23 shown by clinical trials, highlighting the efficacy and safety profiles of this new class of biologics also in clinical practice.

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.

Comorbidity in Adult Psoriasis: Considerations for the Clinician

Psoriasis is associated with several comorbidities ranging from cardiovascular comorbidity and mental disorders to other immune mediated inflammatory diseases. However, most of these co-morbidities are often overlooked or diagnosed late. Furthermore, evidence suggests that comorbidities are undertreated. Here, we provide an overview of comorbidities in psoriasis and present a simple rundown of considerations of relevance to the clinician. We hope that this review may raise clinicians' awareness of comorbidities in psoriasis and provide simple guidance regarding screening tools and treatment decisions in psoriasis with comorbidities.

Evaluation of ocular surface epithelial and stromal thicknesses in psoriasis using anterior segment optical coherence tomography

PURPOSE

To evaluate the epithelial and stromal thicknesses of conjunctiva and cornea in psoriatic patients with anterior segment optical coherence tomography (AS-OCT), METHODS: In this cross-sectional study, 61 patients with psoriasis and 42 age-matched, healthy individuals were enrolled. The epithelial and stromal thicknesses of both inferotemporal bulbar conjunctiva and central cornea were measured using AS-OCT.

RESULTS

Both the tear breakup time and Schirmer-1 test values were significantly lower in the psoriasis group compared with the controls (p < 0.05). The epithelial thickness of conjunctiva and cornea did not differ between psoriasis and control groups (p > 0.05). The central corneal stroma was significantly thicker in the psoriasis group (p = 0.04). PASI was positively correlated with the thickness of central cornea stroma (r = 0.442, p = 0.006) in the nail psoriasis group.

CONCLUSIONS

Psoriasis is not associated with altered epithelial thicknesses of the cornea and conjunctiva. It is accompanied by the stromal thickening of the cornea without conjunctival stromal involvement.

Identifying and Treating Ocular Manifestations in Psoriasis

Psoriasis is a chronic immune-mediated inflammatory skin condition that commonly presents with red, thickened, and scaling plaques. Given the prominent cutaneous manifestations of psoriasis, more subtle ophthalmic findings of the disease may initially go undetected, with the potential for significant ocular morbidity. Associated ocular disease can involve nearly any structure of the eye, with the eyelids most commonly being affected, resulting in relatively common signs and symptoms of ocular surface discomfort. The presence of intraocular inflammation (i.e., uveitis) or retinal involvement carry a heightened risk of vision loss, and are often more difficult to diagnose outside of the ophthalmology clinic. Early detection and treatment of ocular disease can limit morbidity and are critical to the management of these patients, which requires coordination of care between dermatologists and ophthalmologists. The objective of this article was to review the most common ocular conditions that affect psoriatic patients, when to consider referral to an ophthalmologist, and to summarize the adverse ocular effects of current psoriasis treatments.

Risk of incident cataract in patients with psoriasis: A population-based cohort study

Patients with psoriasis are predisposed to ocular complications. However, there is a paucity of data addressing the association between psoriasis and subsequent cataract development. The present study was conducted to evaluate whether there is an increased risk of cataract among patients with psoriasis. The study subjects of this cohort study were selected based on Chang Gung Research Database from 1 January 2003 to 31 December 2012. Follow-up ended 31 December 2017. Patients aged 20 years and older with psoriasis were enrolled. The participants of the control group were selected by matching with sex, age, and index date at a 4:1 ratio. Patients previously diagnosed with cataract were excluded. The hazard ratios associated with psoriasis were estimated using Cox regression analysis with competitive risk model. We also evaluated the relationship between the risk of cataract and systemic therapies as well as phototherapy and topical corticosteroid in patients with psoriasis. A total of 6823 patients with psoriasis and 27 292 matched controls were enrolled in the study. The psoriasis group had higher incidence rates than the control group for cataract (44.08 vs 19.45 per 10 000 person-years; adjusted hazard ratio, 1.778 [95% confidence interval, 1.530-2.066; p < 0.001]). Psoriatic patients receiving phototherapy for more than 200 sessions had a higher risk of cataract (adjusted hazard ratio, 2.933; 95% confidence interval, 1.192-7.218; p = 0.019), especially those receiving narrowband ultraviolet B therapy. The present study demonstrated a positive association between psoriasis and cataract. Physicians should be alert to visual function in patients with psoriasis, especially those receiving long-term phototherapy.

Managing Psoriatic Arthritis With Inflammatory Bowel Disease and/or Uveitis

Psoriatic arthritis (PsA) is a chronic inflammatory disease that presents with psoriasis (PsO), peripheral and axial arthropathy. The heterogeneity of disease presentation leads to the term "psoriatic disease (PsD)" which is thought to better encompass the range of clinical manifestations. PsA is associated with several comorbidities such as cardiovascular diseases, metabolic syndrome and other extra-articular manifestations including uveitis, and inflammatory bowel disease (IBD). While novel therapeutics are being developed following advances in our understanding of the pathogenesis of the disease, the diverse combinations of PsA with its various comorbidities still pose a clinical challenge in managing patients with PsA. This article reviews our current understanding of the pathogenesis of PsA and how various pathways in the pathogenesis lead to the two comorbid extra-articular manifestations - uveitis and IBD. We also review current evidence of treatment strategies in managing patients with PsA with comorbidities of uveitis and/or IBD.
