Active Tuberculosis in Patients with Psoriasis Receiving Biologic Therapy: A Systematic Review

  • SYSTEMATIC REVIEW

American Journal of Clinical Dermatology Aims and scope Submit manuscript

Abstract

Background

Biologic therapies pose a risk for opportunistic infections, especially for reactivating latent tuberculosis infection (LTBI).

Objective

The aim was to describe the clinical features and mortality rate of active Mycobacterium tuberculosis (TB) in psoriasis patients receiving biologic therapies.

Methods

A systematic review of PubMed, Google Scholar, ScienceDirect, Cochrane Library, and ClinicalTrials.gov databases was performed. Studies describing active TB in patients with psoriasis receiving biologic therapy from inception to May 31, 2018 were included. Clinical data as well as mortality rates were recorded.

Results

Fifty-one studies were included, evaluating 78 patients with active TB: 11 prospective studies, 13 retrospective, and 27 case reports/series. Most patients (73%) with active TB were male, the mean age was 48 ± 13 years, and 85% were of European or Asian origin. Pre-treatment LTBI screening was negative for 63% of patients. Disease presented in 33% of patients within the first 3 months of treatment, and in 51% within the first 6 months. Most patients (72%) presented with extra-pulmonary TB, and 49% had disseminated disease. The mortality rate was 7%.

Limitations

Limitations of this review are its small sample size and inclusion of case reports.

Conclusions

Some patients develop active TB despite LTBI screening. Clinicians initiating biologic therapy in patients with psoriasis should be aware of the clinical features of active TB in this scenario.
