Moderate-to-severe atopic dermatitis pathophysiology

Watch Professor Seemal Desai (biography) draw on his experience to provide up-to-date knowledge as he talks about the pathophysiology of moderate-to-severe atopic dermatitis and associated treatment options.

What is the importance of epidermal hyperplasia in atopic dermatitis?


A combination of factors influences the development of epidermal hyperplasia in atopic dermatitis. Hear Professor Desai add insight into what is known of its pathogenesis. Further your understanding of the pathways involved in epidermal hyperplasia, knowledge which is key to providing targeted therapeutics and realising improvements for patients.

Can you describe some of the key hypotheses and research areas for the pathogenesis of atopic dermatitis?


Refresh your knowledge of the complex molecular interactions that influence the development of atopic dermatitis. As we learn more about the inflammatory response involved, Professor Desai focuses attention on key cytokines associated with cellular responses mediated by the JAK-STAT signalling pathway.

How can understanding of the role of Janus kinase (JAK) proteins in atopic dermatitis help target treatment?


For patients with moderate-to-severe atopic dermatitis, where there are limitations to treatment with topical agents or systemic immunosuppressants, finding more targeted therapies is key. Professor Desai is involved in clinical trials and a leader within the FDA – well placed to explain the thinking behind the development and use of therapeutics. Listen to him explore molecules that target the involvement of Janus kinase proteins in membrane binding and signalling.

Which cytokines are key targets in atopic dermatitis?


Are you up to date with the latest research and understanding of cytokines that play a key role in moderate-to-severe atopic dermatitis? Find about more about the central players in this auto-inflammatory skin disease.

Which investigational treatments offer exciting potential for the treatment of atopic dermatitis?


Hear Professor Desai explore the promise of a number of specific JAK inhibitor pipeline molecules, including where they are in clinical trials and if and when we might hope to see them available for use.

What are key topics of discussion with patients for clinicians treating moderate to severe atopic dermatitis?


It is vital for those involved in treating atopic dermatitis to keep patient priorities central to their clinical approach. Ensure you are clear about the interplay between patient and clinician goals in order to effectively manage consultations and remember the key topics to explore with those living with the reality of atopic dermatitis.

Pruritis in atopic dermatitis

Professor Martin Steinhoff’s (biography) interest in atopic dermatitis is mainly around the pathophysiology and management of pruritis and understanding the neuroimmunology of the condition. Watch the videos below to hear him share expertise in these areas.

What is the burden of atopic dermatitis for patients?


Without getting into the skin of a patient with atopic dermatitis, can you truly understand the severity of pruritis? Professor Steinhoff emphasises the many ways in which the burden of itching can impact an individual’s life – from serious limitations on everyday activities to life-changing psychological impact. You may identify with what you’ve have encountered in your own clinical practice as you hear about patients describing pruritis as the symptom for which they require most urgent help.

What are the underlying mechanisms of pruritus in atopic dermatitis?


Understanding the pathological mechanisms underpinning the experience of pruritis is vital to treating atopic dermatitis successfully. Listen to Professor Steinhoff provide a clear description of the multiple stimuli that activate neuronal pathways and contribute to the “itch-scratch cycle”. Hear him explain why, therefore, more than one approach to managing pruritis is required.

What is the itch-scratch cycle and what factors influence it?


The itch-scratch cycle is a serious challenge for patients, but is it always fully understood and clearly addressed? Ensure you appreciate the interplay between the dysfunction of the skin barrier in atopic dermatitis, the inflammatory factors at play, the role of central nervous system pathways, and the cause and effect of itching and scratching.

What are the remaining unmet needs and challenges to overcome when managing pruritus?


What more can we do to manage atopic dermatitis effectively and bring real therapeutic benefit to patients? Professor Steinhoff draws on longstanding expertise and experience to add insights, including for those with recalcitrant atopic dermatitis and pruritis. As he explores aspects of care from education and awareness right through to the realistic provision of treatments where they are needed, he provides us with a framework for priorities and practicalities moving forwards.

What are three key things to know about pruritus in atopic dermatitis and its treatment?


Listen to Professor Steinhoff focus attention on what he believes to be the most important things to appreciate when caring for those with atopic dermatitis. He emphasises a patient-centric approach, and provides vital advice to clinicians regarding management, self-education and the knowledge that needs to underpin treatment decisions. As we look to the future of atopic dermatitis care, Professor Steinhoff’s insights may help to ensure you are able to effectively provide help and relief for people living with this heterogenous condition.

PDE4 inhibition in atopic dermatitis

Explore how the phosphodiesterase-4 (PDE4) enzyme fits into the pathophysiology of atopic dermatitis with our expert Michael Cork, Professor of Dermatology at the University of Sheffield. Also learn about its potential as a therapeutic target and glimpse into the future with a look into upcoming clinical trials comparing PDE4 inhibitors to topical corticosteroids (TCS).

How is PDE4 involved in the pathophysiology of atopic dermatitis?

Professor Cork describes the central role of the PDE4 enzyme in regulating the release of a variety of inflammatory cytokines involved in the development of atopic dermatitis.


The pathophysiology of atopic dermatitis is complex and multifaceted, involving various elements such as skin barrier dysfunction, alterations to immune responses and environmental factors (Figure 1). Learn how elevated levels of PDE4 play a key role in the development of atopic dermatitis.

 

Expert op_AD_Fig1

Figure 1: cAMP is present at high levels within a variety of cells with PDE4 regulating its breakdown. However, it has been shown that patients with atopic dermatitis display elevated levels of PDE4 in circulating inflammatory cells, resulting in a reduction in cAMP and an increase in the production of a variety of proinflammatory cytokines such as IL-4, IL-5 and IL-17. Adapted from: Purushothaman et al. 20185. AC, Adenylyl cyclase; ATP, adenosine triphosphate; AMP, adenosine monophosphate; cAMP, cyclic adenosine monophosphate; IgE, immunoglobulin E; IL, interleukin; PDE4, phosphodiesterase-4.

Why is PDE4 an attractive therapeutic target?

Find out why PDE4 inhibitors have become a therapeutic target of interest, with Professor Cork, in this short video.


Limited choices in the range of topical treatments for atopic dermatitis has led to a great interest in developing new non-steroidal anti-inflammatory therapies. Topical PDE4 inhibitors have become an attractive therapeutic target utilising a unique mechanism of action (Figure 2).

 

Expert op_AD_Fig2

Figure 2: Selective inhibition of PDE-4 prevents the degradation of cAMP to AMP. Increased levels of cAMP suppress the activity of NF-κB, NFAT and other pathways responsible for inflammatory cytokine production. This favourably suppresses the synthesis of inflammatory cytokines and subsequently arrests the development of atopic dermatitis via modulating the intracellular cAMP levels. (Adapted from: Oswald K 20176). AMP, adenosine monophosphate; cAMP, cyclic adenosine monophosphate; IFN-y, interferon gamma; IL, interleukin; NFAT, nuclear factor of activated T-cells; NF-κB, nuclear factor-κB; PDE4, phosphodiesterase-4; TNF-α, tumour necrosis factor-α.

How do topical PDE4 inhibitors differ from oral options?

Learn about the differences between topical and oral PDE4 inhibitors and the benefits topical treatments can provide.


Targeted therapies that function at the site of action can provide significant advantages over oral forms of the same drug. Find out how topical and oral PDE4 inhibitors differ from each other in terms of bioavailability, systemic exposure and adverse events.

How is PDE4 currently being evaluated in clinical trials for atopic dermatitis?

Discover the trials that are currently on pause in Europe that will directly compare TCS with PDE4 inhibitors.


Phase three trials have provided significant efficacy and safety data for PDE4 inhibitors7. However, more research is needed to understand their effect on the skin. While COVID-19 is has put many clinical trials on pause, trials planned in Europe aim to compare the effect of TCS and PDE4 on atrophy of the epidermis.
