The Tuberculosis Positive Conversion Rate Among Psoriasis Patients Treated with Adalimumab and Secukinumab: A Single-Center Retrospective Study in China.

Abstract

INTRODUCTION:

The tuberculosis (TB) positive conversion rate among psoriasis patients who received biologics has been reported worldwide, particularly in regions with low TB risk. Nonetheless, the TB-related safety of biologics such as adalimumab and secukinumab remains elusive in areas with high TB risk. According to the World Tuberculosis Report 2021, China is the country with the second highest TB burden, but data on TB conversion are also limited. Thus, we performed a retrospective, single-center study to profile the TB infection status conversion ratio among psoriasis patients treated with adalimumab and secukinumab in China.

METHODS:

Patients were enrolled between April 2019 and February 2021 from West China Hospital, Sichuan University. Baseline and relevant clinical information were summarized, and proper statistical analysis was used under different conditions.

RESULTS:

Five (5.43%) patients suffered TB conversion in the adalimumab group, two of whom developed active TB within the first 6 months. In the secukinumab group, four (5.26%) patients had TB positive conversion with no reports of active TB.

CONCLUSION:

Our data show a relatively high rate of TB conversion among these psoriasis patients after mean treatment duration of 17.13 months. We recommend that, in patients who receive adalimumab, TB be reevaluated after the first 3 months and then monitored semiannually for the next 2 years. For patients treated with secukinumab, annual examination is sufficient.
