Use of oral immunosuppressive drugs in the treatment of atopic dermatitis in the Netherlands

Abstract

Background

Although atopic dermatitis (AD) is a very common skin disease, data on the percentage of patients with really difficult to treat AD are scarce. From socio-economic perspective it is important to have more insight in these numbers, as new very effective, but expensive, treatment options will be available in the near future for difficult to treat AD. Estimating the number of AD patients using oral immunosuppressive drugs can give an impression of the percentage of difficult to treat patients in the total AD population.

Objective

To give an overview of the use of oral immunosuppressive drugs in patients with AD in the Netherlands.

Methods

Prescription data of oral immunosuppressive drugs in the Netherlands were extracted from a pharmaceutical database (NControl) containing data of 557 million prescriptions and 7.2 million patients. An algorithm, based on the WHO Anatomical Therapeutic Chemical (ATC) codes, was used to identify patients with AD. The prescription of oral immunosuppressive drugs in patients with AD between January 1st 2012 and January 1st 2017 was evaluated.

Results

Based on the algorithm, 65 943 patients with AD were selected. 943 AD patients (1.4%) used cyclosporine A, methotrexate, azathioprine or mycophenolic acid. Methotrexate was most commonly used, followed by azathioprine and cyclosporine A. A switch in medication was rarely seen. In the evaluation period a decrease in the prescription of cyclosporine A was seen, together with an increase of the prescription of methotrexate. In 31% of the patients who stopped treatment, the discontinuation took place within the first months of treatment.

Conclusion

In this study population, 1.4% of the AD patients used oral immunosuppressive drugs for their eczema in a five year period. Methotrexate was the most commonly used systemic drug in the Netherlands for the treatment of AD.
