Prevalence of positive QuantiFERON Gold In-Tube testing in Hidradenitis Suppurativa.

Prevalence of positive QuantiFERON Gold In-Tube testing in Hidradenitis Suppurativa. J Dermatolog Treat. 2018 Jan 12;:1-16 Authors: Boortalary T, Misra K, McNish S, Jones D, Shanmugam VK Abstract Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory disease of the apocrine sweat glands. Tumor necrosis factor-alpha (TNF-α) inhibitors are commonly used to treat HS. However, prior to initiating therapy patients must be screened for mycobacterium tuberculosis (mTB) exposure. Several mTB screening tests based on interferon gamma release assays are commercially available, but the performance of these assays in the HS population is unknown. The purpose of this study was to investigate the performance of the QuantiFERON gold in-tube assay (QFT-GIT) in a cohort of patients with Hidradenitis suppurativa (HS). This prospective study was conducted through the Wound Etiology and Healing (WE-HEAL) Study. QFT-GIT testing was performed using a commercial laboratory. Patients with positive test results underwent follow-up testing to evaluate for latent tuberculosis infection (LTBI). Data was collected on demographics and disease activity scores including Hurley stage, HS Sartorius score (HSS) and active nodule (AN) count. Of the 69 patients with a confirmed diagnosis of HS, 7 (10.1%) tested QFT-GIT positive and 5.8% were diagnosed with LTBI. QFT-GIT results did not correlate with demographic characteristics or HS disease activity. ...
