Special aspects of biologics treatment in psoriasis: management in pregnancy, lactation, surgery, renal impairment, hepatitis and tuberculosis

2023 guidelines on the management of psoriasis by the Dermatological Society of Singapore

Introduction

Psoriasis is a multisystem, chronic, inflammatory dermatological disease. In routine clinical practice, the management of psoriasis varies significantly. The current study aimed to develop a set of practice guidelines relevant to dermatology practice in Singapore.

Method

The Psoriasis Therapeutic Guidelines Workgroup, comprising members of the Dermato-logical Society of Singapore with a subspecialisation in psoriasis, was convened to develop the guidelines. Clinical questions on selected topics were generated and refined by the workgroup. A literature search using PubMed was performed on their assigned topics from June 2013 to December 2023. The articles were included and graded based on the level of evidence.

Results

The guidelines address topics ranging from clinical assessment to practical considerations in the management of mild, moderate and severe psoriasis, including delivery of care, referrals to specialists and adherence to treatment. The recommended therapies include phototherapy, methotrexate, acitretin, cyclosporine; apremilast; topical corticoste-roids, calcipotriol, topical calcineurin inhibitors; and biologics (i.e. adalimumab, infliximab, secukinumab, ixekizumab, ustekinumab, etanercept) either in combina-tion or as monotherapy. Common therapeutic concerns relating to biologic use were addressed. Recommendations on generalised pustular psoriasis, palmoplantar pustular psoriasis and psoriatic arthritis were also made. Patients on systemic therapy would receive appropriate vaccine counselling. Therapeutic implica-tions in special populations, such as pregnant/ lactating women, children, the elderly, those undergo-ing surgery and those suffering from specific infections and cancer were addressed.

Conclusion

These guidelines were developed for dermatologists, family physicians, rheumatologists and other specialists to support their selection of appropriate management options.

The PI3K-Akt-mTOR and Associated Signaling Pathways as Molecular Drivers of Immune-Mediated Inflammatory Skin Diseases: Update on Therapeutic Strategy Using Natural and Synthetic Compounds

The dysregulated phosphatidylinositol-3-kinase (PI3K)-Akt-mammalian target of rapamycin (mTOR) signaling pathway has been implicated in various immune-mediated inflammatory and hyperproliferative dermatoses such as acne, atopic dermatitis, alopecia, psoriasis, wounds, and vitiligo, and is associated with poor treatment outcomes. Improved comprehension of the consequences of the dysregulated PI3K/Akt/mTOR pathway in patients with inflammatory dermatoses has resulted in the development of novel therapeutic approaches. Nonetheless, more studies are necessary to validate the regulatory role of this pathway and to create more effective preventive and treatment methods for a wide range of inflammatory skin diseases. Several studies have revealed that certain natural products and synthetic compounds can obstruct the expression/activity of PI3K/Akt/mTOR, underscoring their potential in managing common and persistent skin inflammatory disorders. This review summarizes recent advances in understanding the role of the activated PI3K/Akt/mTOR pathway and associated components in immune-mediated inflammatory dermatoses and discusses the potential of bioactive natural products, synthetic scaffolds, and biologic agents in their prevention and treatment. However, further research is necessary to validate the regulatory role of this pathway and develop more effective therapies for inflammatory skin disorders.

Systemic treatment of psoriasis in special population

Psoriasis is a common skin disorder affecting approximately 1% of the general population. The treatment of psoriasis depends on the body surface area involvement, quality of life impairment and associated co-morbidities. Special population comprising of pregnant women, lactating mothers, elderly individuals and children, is more vulnerable. They are not included in drug trials; rendering the data for use of systemic treatment scant and is mainly based on anecdotal evidence. In this narrative review, we discuss systemic treatment options in this special population. Though couples planning a family are not considered a special population, they form a subset that require special therapeutic consideration and have also been included in this review.

The role of topical therapies along the psoriasis patient journey: An overview from the Symposium 'Tailoring topical psoriasis treatments to patients' needs and expectations' of the 30th EADV Congress 2021

This article summarizes a presentation titled 'The role of topical therapies along the psoriasis patient journey' held at the Satellite Symposium of the 30^th European Academy of Dermatology and Venereology Congress. During this session, the role of topical treatments in the management of psoriasis was presented, with a particular focus on the current unmet needs and data gaps. Psoriasis plays a significant role in a patient's daily life, impacting them not only physically but also psychologically and socially. The disease burden increases with duration and severity. Topical therapies are the keystone of the management of psoriasis. About 70%-80% of patients present a mild-to-moderate form of psoriasis that can be successfully treated with topical agents. According to a German recommendation, patients with mild psoriasis should initiate a topical therapy in combination with skin care products. In the real-life setting, the calcipotriol/betamethasone dipropionate (CAL/BDP) fixed combination was the most prescribed topical treatment for beyond-mild patients in Germany, Spain and the United Kingdom. Healthcare professionals also often or very often prescribed topicals as an alternative to non-biologic systemics in certain situations, such as patient preference (51%), contraindication (50%) and to limit side effects (26%). Adjunctive topical therapy to patients using systemic therapy is used to optimize treatment outcomes and improving the quality of life for patients. Topical treatments can be also effective in severe forms of psoriasis. However, there are still some gaps and unmet needs on topical therapy. Ineffectiveness, patient dissatisfaction and adherence are the largest barriers to treatment success. Main strengths of topical treatments include the availability of various topical ingredients and galenics, the adaptability to different anatomical areas and the possible combination with phototherapy and systemics. Moreover, patients in specific situations can benefit from switching to topical treatments (e.g. pregnancy or surgery).

[Translated article] Practical Update of the Guidelines Published by the Psoriasis Group of the Spanish Academy of Dermatology and Venereology (GPs) on the Treatment of Psoriasis With Biologic Agents: Part 2-Management of Special Populations, Patients With Comorbid Conditions, and Risk

BACKGROUND AND OBJECTIVES

Since its inception, the Psoriasis Group (GPs) of the Spanish Academy of Dermatology and Venereology (AEDV) has worked to continuously update recommendations for the treatment of psoriasis based on the best available evidence and incorporating proposals arising from and aimed at clinical practice. An updated GPs consensus document on the treatment of moderate to severe psoriasis was needed because of changes in the treatment paradigm and the approval in recent years of a large number of new biologic agents.

METHODOLOGY

The consensus document was developed using the nominal group technique complemented by a scoping review. First, a designated coordinator selected a group of GPs members for the panel based on their experience and knowledge of psoriasis. The coordinator defined the objectives and key points for the document and, with the help of a documentalist, conducted a scoping review of articles in Medline, Embase, and the Cochrane Library up to January 2021. The review included systematic reviews and meta-analyses as well as clinical trials not included in those studies and high-quality real-world studies. National and international clinical practice guidelines and consensus documents on the management of moderate to severe psoriasis were also reviewed. The coordinator then drew up a set of proposed recommendations, which were discussed and modified in a nominal group meeting. After several review processes, including external review by other GPs members, the final document was drafted.

RESULTS

The present guidelines include updated recommendations on assessing the severity of psoriasis and criteria for the indication of systemic treatment. They also include general principles for the treatment of patients with moderate to severe psoriasis and define treatment goals for these patients as well as criteria for the indication and selection of initial and subsequent therapies Practical issues, such as treatment failure and maintenance of response, are also addressed.

TNF-alpha inhibitors and ustekinumab for the treatment of psoriasis: therapeutic utility in the era of IL-17 and IL-23 inhibitors

Psoriasis is a chronic inflammatory condition for which eleven FDA-approved biologic therapies are approved. Over the past decade, studies have documented the higher efficacy of IL-17 and IL-23 inhibitors for the treatment of psoriasis compared to the TNF-alpha inhibitors and ustekinumab, an IL-12/23 inhibitor. Despite this, there remains an important role for the use of TNF-alpha inhibitors and ustekinumab in the treatment of psoriasis. Here, we review how considerations of infection and malignancy risk, patient demographics, treatment resistance, and co-morbidities may make certain TNF-alpha inhibitors or ustekinumab an excellent choice for therapy in particular patient subgroups.

Practical recommendations for systemic treatment in psoriasis according to age, pregnancy, metabolic syndrome, mental health, psoriasis subtype and treatment history (BETA-PSO: Belgian Evidence-based Treatment Advice in Psoriasis; part 1)

Background

Impressive progress in new therapeutic options has been made for psoriasis. Treatments include topical steroids, phototherapy, conventional, synthetic disease‐modifying drugs and an expanding list of biologics.

Objective

The primary objective of this work was to collect evidence for the creation of practice guidelines for systemic treatment of psoriasis (BETA‐PSO: Belgian Evidence‐based Treatment Advice in Psoriasis).

Methods

Evidence‐based recommendations were formulated using a quasi‐Delphi methodology after a systematic search of the literature and a consensus procedure involving 8 psoriasis experts.

Results

In this part, the use of systemic treatment in different age groups, during pregnancy, in metabolic syndrome, in patients with mental health problems, in different psoriasis subtypes and in previously systemically treated patients treatment is discussed.

Conclusion

Guidance on therapeutic choice in specific clinical situations in psoriasis is provided in order to facilitate the decision‐making in clinical practice.

The use of biological drugs in psoriasis patients prior to pregnancy, during pregnancy and lactation: a review of current clinical guidelines

Introduction

Information on the possibility of using biological drugs in psoriasis patients planning to conceive, patients who are pregnant or during lactation is limited.

Aim

Presenting recommendations published in clinical guidelines regarding the use of biological drugs – adalimumab, brodalumab, certolizumab pegol, etanercept, guselkumab, infliximab, ixekizumab, risankizumab, secukinumab, tildrakizumab, and ustekinumab, by psoriasis patients in the period of planning pregnancy, during pregnancy or during lactation.

Material and methods

The paper was based on a comprehensive review of over 40 websites of HTA agencies, dermatological associations worldwide and medical databases (PubMed, Embase), the objective of which was to identify clinical guidelines relating to biological treatment of women of childbearing potential, published after 2018, which used GRADE – a system for rating the quality of a body of evidence.

Findings

Certolizumab pegol is recommended in women who are planning to conceive. Furthermore, guidelines indicate other TNF-α inhibitors as possible treatment. Certolizumab pegol is also recommended as first-line treatment in pregnant patients. Furthermore, for trimesters 2 and 3, guidelines allow using other TNF-α inhibitors. Treatment with secukinumab and ustekinumab should be discontinued when planning pregnancy or when pregnancy was diagnosed. Biological treatment during pregnancy and lactation (continuation or initiation of treatment) can be used only after an analysis of risks and benefits has been conducted.

Conclusions

TNF-α inhibitors seem to be the safest and most researched biological drugs used in psoriasis treatment of patients planning to conceive, during pregnancy or lactation. Given its non-existent or minimal placental permeability, most likely the safest alternative is certolizumab pegol.

Management of psoriasis in pregnancy - a review of the evidence to date

The onset of psoriasis collides with women’s reproductive timeframe, and pregnancy brings challenges to its treatment. Indeed, the health of both mother and foetus must be considered. When choosing to treat pregnant women affected by psoriasis with pharmacological therapy, it is important to be aware of all possible options and their repercussions. Although there are several pharmacological therapies available, pregnancy brings ethical concerns and any pharmacological approach must be well thought out. The data available in humans are limited, and further investigation on this matter is needed. Within biological therapies, certolizumab pegol has recently been identified as a promising approach during pregnancy because it has been shown to have no late active placental transfer and no clear signs of foetal harm. This article aims to review the impact of psoriasis during pregnancy, how the disease can be managed pharmacologically during this period according to the available armamentarium, and the possible effects of the therapeutic options for the mother and the foetus.
