Eczema and Clinical Trials

Atopic dermatitis, commonly known as eczema, is a skin condition that affects millions of people across the globe. The National Eczema Association, reports that 31 million Americans suffer from one form of eczema.1


The disease is characterized by the formation of itchy patches that become inflamed (dermatitis means inflammation of the skin) and may crack. The conversion of patches into blisters is also seen in some cases. These dry, crusted and scaly patches can occur on different parts of the body. The condition affects both children and adults.


Keeping in mind the high prevalence of the skin condition, atopic dermatitis needs to be treated effectively. However, there is no definitive cure for eczema, and doctors are left with symptom management only. The good news is that research is being conducted, and with every passing day, we are inching towards a permanent solution.


Let's have a look at the current treatment strategies.


Topical Steroids and Anti-Inflammatory Drugs

Topical steroids are the first line of treatment for eczema, and they have shown promising results. It is recommended to use topical steroids for not more than 6 weeks and to use under medical supervision.2


Calcineurin inhibitors are specialized drugs that suppress the immune system, thereby preventing flares. Based on the latest analyses, researchers advocate the use of topical steroids along with calcineurin inhibitors for hand eczema. 3


Vitamin Supplements

Alitretinoin is a compound similar to vitamin A that is sufficient in treating severe and refractory forms of chronic hand eczema in most individuals. 4 The vitamin-like drug can be applied topically. It is considered to be highly effective and safe in use for pediatric chronic hand eczema patients. 5 Alitretinoin needs to be given for longer durations and in higher doses to be most effective. 6


Antibody Treatment

The use of antibodies (Ig) therapy is gaining popularity rapidly. Dupilumab is a monoclonal antibody that inhibits the activity of interleukins (chemicals involved in the progression of disease). Dupilumab therapy is well-tolerated by most patients as a long term treatment option for atopic dermatitis patients. 7


Systemic Corticosteroids

The use of systemic corticosteroids is reserved for cases that are non-responsive to topical therapy. The International Eczema Council has a consensus on abstaining from routine usage of systemic corticosteroids; stating they should be reserved for special circumstances. 8


Phototherapy

Dermatologists in Europe prefer prescribing phototherapy for the management of chronic eczema in infants and adults. Eczema phototherapies are typically used for whole-body cases and involve using a narrow band of UV light to treat the affected areas. Topical antibiotics and phototherapies are considered the first line of treatment for moderate to severe eczema. 9
