Incidence of New-Onset Inflammatory Bowel Disease, Oral and Gastrointestinal Candidiasis, Herpes Zoster, Pulmonary Tuberculosis, and Major Cardiovascular Events in Patients with Moderate-to-Severe Psoriasis Exposed to Biologics

The multicenter, retrospective cohort study was aimed at examining adverse events in biologic-treated patients with moderate-to-severe psoriasis by using a real-world database. Thus, we analyzed exposure-adjusted incidence rates for new-onset inflammatory bowel disease (IBD), oral and gastrointestinal candidiasis, pulmonary tuberculosis, herpes zoster, and major cardiovascular events (MACEs) in biologic-treated patients with moderate-to-severe psoriasis. Overall, 2085 patients were found to have been exposed to tumor necrosis factor (TNF)-alpha, interleukin (IL)-12/23, IL-17, and IL-23 inhibitors (n = 463, 540, 635, and 447, respectively). No patient developed new-onset IBD. The incidence rates of oral and gastrointestinal candidiasis were comparable between patients treated with IL-23 and IL-17 inhibitors (5.6 and 5.3 per 1000 PY, respectively). None treated with IL-17 or IL-23 inhibitors reported pulmonary tuberculosis. The incidence rate of herpes zoster was the highest in patients treated with TNF-alpha inhibitors (17.0 per 1000 PY), followed by IL-17, IL-23, and IL-12/23 inhibitors (13.3, 7.8, and 2.7 per 1000 PY, respectively). MACEs were not reported in patients treated with IL-17 inhibitors but were reported in those treated with TNF-alpha, IL-23, and IL-12/23 inhibitors (incidence: 5.6, 3.8, and 1.8 per 1000 PY, respectively). The study indicated favorable safety profiles of biologics in Korean patients with moderate-to-severe psoriasis.
