Psoriasis in children

Australian consensus: Treatment goals for moderate to severe psoriasis in the era of targeted therapies - Considerations for paediatric patients

BACKGROUND

Treatment goals have been established in Australia to facilitate the management of adults with moderate to severe psoriasis. The Australasian College of Dermatologists sought to determine if and how these adult treatment goals could be modified to accommodate the needs of paediatric and adolescent patients.

METHODS

A modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7-9 on a 9-point scale (1 strongly disagree; 9 strongly agree).

RESULTS

Consensus was achieved on 23/29 statements in round 1 and 17/18 statements in round 2. There was a high level of concordance with treatment criteria in the adult setting. The limitations of applying assessment tools developed for use in adult patients to the paediatric setting were highlighted. Treatment targets in the paediatric setting should include objective metrics for disease severity and psychological impact on the patients and their family, and be based on validated, age-appropriate tools.

CONCLUSION

While the assessment, classification and management of moderate to severe psoriasis in paediatric patients aligns with metrics established for adults, it is vital that nuances in the transition from childhood to adolescence be taken into account. Future research should focus on psoriasis severity assessment scales specific to the paediatric setting.

Administration Details of Genetically Engineered Biologic Drug (Ustekinumab) in Children with Psoriasis and Comorbid Metabolic Syndrome or in Case of Previous Biological Therapy Failure: Case Studies

Background. Psoriasis is a chronic immune-mediated disease with multifactorial nature. It often requires administration of genetically engineered biologic drugs. They have a number of features and risks that depend on various factors. The results of ustekinumab administration as a drug of choice in patients with comorbid metabolic syndrome in a child with Down syndrome, as well as a case of inefficacy of previous biologic therapy with TNFα inhibitors are considered. Clinical cases description. Two clinical cases of ustekinumab administration in children with severe psoriasis have been described. In the first case, we had to choose systemic therapy for the child suffering from Down syndrome and having complex comorbid background: obesity and steatohepatitis. The second case was interesting due to the family history of psoriasis in the patient, who received methotrexate for a long time, and then etanercept with subsequent loss of efficacy and severe disease aggravation without any pathogenetic therapy. Conclusion. Ustekinumab is the favorable genetically engineered biologic drug (according to the studies results and the clinical cases data) for children with severe psoriasis who have comorbid pathologies and who require the change in biologic agent due to its inefficacy.

Biological Treatments for Pediatric Psoriasis: State of the Art and Future Perspectives

Psoriasis is a chronic systemic inflammatory disease that primarily affects the skin and is associated with multiple comorbidities with a considerable reduction in quality of life of affected patients. One-third of psoriasis cases begin in childhood and are associated with significant medical comorbidities such as obesity, metabolic syndrome, arthritis, and psychiatric disorders. In addition, because of its chronic nature and frequent relapses, psoriasis tends to require long-term treatment. Treatment of pediatric psoriasis usually involves the same methods used for adults. However, most treatments for pediatric psoriasis are used off-label, and research in this regard is still lacking. Targeted therapies involving the use of newly developed biologic drugs are also increasingly being applied to childhood psoriasis. This review summarizes the clinical features of pediatric psoriasis and focuses mainly on the updated concepts of pathogenesis and biological treatments of pediatric psoriasis.

Managing Pediatric Psoriasis: Update on Treatments and Challenges-A Review

BACKGROUND

Psoriasis is a chronic, immune-mediated inflammatory disease with prominent cutaneous features, although the limited number of medications approved for pediatric psoriasis makes treating this population difficult. This review provides an overview of the challenges associated with diagnosing and treating pediatric psoriasis as well as the approved and off-label treatments for children and infants with psoriasis.

METHODS

Articles relevant to pediatric psoriasis were identified using series of PubMed searches. Topics relevant to pediatric psoriasis were explored, including disease characteristics, epidemiology, treatment efficacy and safety, and access to care. Publications previously known to the authors were also included.

RESULTS

Clinical features of psoriasis can be challenging to identify clinically, and patients face challenges gaining access to treatment. Most medications that have been approved for adult psoriasis lack data and labelling to support safe and effective use in pediatric patients, and therefore access is limited. A growing number of clinical trials using biologic agents for pediatric psoriasis aim to broaden available treatment options but may also raise unique concerns associated with the use of these medications in children.

CONCLUSION

Pediatric psoriasis is underrecognized and often undertreated. Clinicians must balance relative risks and potential benefits when developing a treatment strategy for these patients.

Adalimumab Biosimilar Efficacy and Safety in a 5-Year-Old Patient with Severe Plaque Psoriasis During SARS-CoV-2 Pandemic Outbreak

BACKGROUND: Psoriasis is a chronic inflammatory disease that affects 2% of population. About 0.5–2% of psoriatic cases develop during pediatric age. In most cases, the condition is responsive to topical treatment. However, a small percentage of children require systemic treatment with conventional systemic drugs or biological agents, such as anti-tumor necrosis factor (TNF)-α. Adalimumab (ADA) is an anti-TNF-α recently approved for pediatric psoriasis in the European Union (from 4 years of age, 2015). CASE PRESENTATION: We describe our experience treating a 5-year-old female patient affected by severe plaque psoriasis with ADA biosimilar during SARS-CoV-2 pandemic outbreak also using teledermatology. CONCLUSION: The case reported in this article highlights the safety and the effectiveness of ADA biosimilar MSB11022 (Idacio®) in the treatment of a 5-year-old female affected by plaque psoriasis and paves the way to bigger trials for a more extensive use of TNF-α inhibitor biosimilars for psoriasis in pediatric population.

Innovative Pediatric Development for Secukinumab in Psoriasis: Faster Patient Access, Reduction of Patients on Control

This manuscript describes the innovative pediatric development strategy of secukinumab in psoriasis. Initially, this pediatric development had been planned early during the adult development program. This is common for most development programs as it is required by law in major regions worldwide. At that time, only limited experience with secukinumab's mechanism of action was available, especially in the pediatric population for which no data had been collected yet. Pediatric extrapolation frameworks were not in use. As a result, a standard pediatric program had initially been proposed requiring two relatively large placebo-controlled pivotal trials. However, as experience with the use of secukinumab grew, so did experience with - and regulatory openness to - innovative quantitative approaches such as extrapolation. It became clear that the pediatric development of secukinumab could be substantially accelerated by these novel ideas. Here we report how these concepts were implemented in the pediatric development program of secukinumab in psoriasis, using a wide range of innovative quantitative techniques. This strategy led to the removal of the placebo arm from one trial, a substantial reduction of the overall sample size in this program, and a significantly faster approval of secukinumab for the pediatric psoriasis population.

Management of psoriasis in children (Review)

Psoriasis is a common long-lasting, inflammatory disease that mainly affects the skin. The incidence of this condition has increased significantly over time and at this point, it affects approximately 1% of children. Psoriasis can appear at any age, including childhood and adolescence, with a higher frequency in girls, an earlier onset being associated with severe psoriasis. The pathology is the result of the interaction between genetics and trigger factors such as infections, stress, diet, obesity, and chemical irritants. Paradoxically, tumor necrosis factor (TNF)-α inhibitors (infliximab, adalimumab) may induce psoriasis in children. Psoriasis is a long-term condition with periods of exacerbation; thus, the quality of life can be affected and patients should receive psychosocial support. Although most children have mild disease and topical treatment is efficient, some cases are challenging to treat. The aim of this review was to provide an overview of the current knowledge concerning the epidemiology, etiology, pathogenesis, clinical features, comorbidities, and treatment of psoriasis in children and also to emphasize the need for a multidisciplinary approach to this complex pathology.

Pediatric Psoriasis: From New Insights into Pathogenesis to Updates on Treatment

Psoriasis is a chronic inflammatory systemic disease primarily affecting the skin, but which often involves considerable comorbidities as well. One-third of psoriasis cases start during childhood. In pediatric psoriasis, an association with several medical comorbidities is also indicated. Furthermore, because of its chronic nature and frequent relapses, psoriatic patients tend to require long-term treatment and experience negative impacts on their quality of life. Considering the different clinical characteristics of pediatric psoriasis, it has recently been presented that the pathogenesis of pediatric psoriasis is distinct from adult psoriasis. Treatment for pediatric psoriasis usually involves the same methods as for adults. However, most treatments in pediatric psoriasis are used off-label and research in this regard is still lacking. Targeted therapies involving newly developed biologics are also increasingly being applied to psoriasis in children. This review summarizes the clinical characteristics of pediatric psoriasis and focuses mainly on the updated concepts of pathogenesis and treatments in pediatric psoriasis. This was undertaken to widen the understanding of these relevant aspects and to provide better management of pediatric psoriasis by clinicians.

An updated guide in the management of psoriasis for every practitioner

BACKGROUND

Psoriasis is one of the most common chronic cutaneous skin disorders, having genetic and immunological components. It is currently unknown what exactly triggers it, or how far reaching are the etiological factors, although great strides have been made in uncovering the pathophysiological cascade. Presently, there is a wide diversity of treatment methods for psoriasis, yet not all are applicable for each patient. Selection of both drug and dosage depends on both the knowledge and experience of the treating dermatologist and also on the specific characteristics of each patient. Therefore, the treating physicians should be made aware of the management possibilities, their advantages and their side effects.

METHODS

We have performed a non-systematic literature review on the current treatment methods for psoriasis. We have included the studies, articles, and prescription information that provided the most relevant information regarding each therapeutic agent. Afterward, we divided the treatment methods according to delivery and illustrated the management protocols for adult, paediatric, and pregnant patients.

DISCUSSION AND CONCLUSIONS

Current therapies are divided into topical drugs, phototherapy, systemic and biological agents. Topical therapies and phototherapy are generally the first and second line of management respectively, being typically effective in treating mild to moderate forms of psoriasis. On the other hand, the chronic moderate to severe forms usually benefit from systemic drugs, whereas biologic agents are reserved for severe or unremitting cases, especially those suffering from psoriatic arthritis. Also of importance is the understanding of the pathophysiological mechanisms in psoriasis and how the selected drugs interfere in the pathological cascade. Furthermore, physicians should be able to recommend the appropriate therapy not only for adults but also for paediatric and pregnant patients as well. In the following manuscript, we present an updated version of these management options, alongside their indications, posology and most common side effects, a guide that may be useful for every practitioner in this field.

Pediatric Psoriasis Comorbidities: Screening Recommendations for the Primary Care Provider

Psoriasis, which affects up to 2% of children may be associated with significant comorbidity, including obesity, diabetes, cardiovascular disease, depression, and reduced quality of life. Screening and decision-making require a multidisciplinary approach with the management of potential comorbidities championed by primary care providers and supported by respective specialists and subspecialists. Research into the comorbidities and systemic manifestations has generated significant data culminating in several proposals for a consensus guideline for both pediatric and nonpediatric populations. Our aim is to provide a summary targeted to the pediatric primary care provider from the best available evidence when caring for children with psoriasis.

Adalimumab in children and adolescents with severe plaque psoriasis: a safety evaluation

Introduction: Psoriasis is a chronic inflammatory systemic disease that affects 2% of the population and is associated with an important physical and physiological burden. About 0.5-2% of psoriatic cases onset during the pediatric age range, and often it's not diagnosed until adulthood. Adalimumab is an antitumor necrosis factor monoclonal antibody approved for use in children in 2008 and now it was used in several diseases in rheumatology, gastroenterology, and in dermatology.Areas covered: The purpose of this article was to summarize what has been described in the literature so far, about safety in the use of adalimumab in pediatric psoriasis. The presented data was extrapolated from a literature review from PubMed searches (using words 'pediatric psoriasis,' 'adalimumab children,' 'adalimumab safety,' 'pediatric psoriasis treatment,' 'adalimumab clinical trial'), treatment guidelines, and reports from European and United States regulatory agencies.Expert opinion: Actually there are some biologic agents for the treatment of pediatric psoriasis, but the lack of safety data from controlled trials is evident. The safety data on the use of adalimumab in pediatric psoriasis was taken from long-term studies in the adult population. These studies confirm the data on the safety of the drug as it is also supported by several works on real-life.

Update in the management of pediatric psoriasis

PURPOSE OF REVIEW

Psoriasis is a multifactorial, chronic, inflammatory skin disease that may represent a therapeutic challenge in children. This review aims to provide a framework for the management of pediatric psoriasis, emphasizing in new insights and considerations for management. It will focus on new disease associations and innovative treatment modalities that challenge current approach of psoriasis in children.

RECENT FINDINGS

There is an increasing body of literature both in adults and in children linking psoriasis with different comorbidities. This new evidence points to the need of addressing psoriasis as a systemic disease and suggests the need for screening and creating awareness of possible associations. In a similar manner, newer medications are also being investigated in children. Recent publications report on the efficacy and safety of biologics for psoriasis in pediatric patients.

SUMMARY

The review provides better understanding of present and future risks of untreated and uncontrolled psoriasis in children and at the same time the benefits and risks of new treatments available.
