We used data from the BIOBADADERM registry (Spanish Registry of Adverse Events for Biological Therapy in Dermatological Diseases) to generate crude rates of infection during therapy with systemic drugs, including biological drugs (infliximab, etanercept, adalimumab, and ustekinumab) and nonbiological drugs (acitretin, cyclosporine, and methotrexate). We also calculated unadjusted and adjusted risk ratios (RRs) (with propensity score adjustment) of infection, serious infections, and recurrent infections of systemic therapies compared with methotrexate, using Poisson regression. Our study included records of 2,153 patients (7,867.5 person-years). The adjusted RR of overall infection was significantly increased in the groups treated with adalimumab with methotrexate (adjusted RR = 2.13, 95% confidence interval [CI] = 1.2-3.7), infliximab (adjusted RR = 1.71, 95% CI = 1.1-2.65), cyclosporine (adjusted RR = 1.58, 95% CI = 1.17-2.15), ustekinumab with methotrexate (adjusted RR = 1.56, 95% CI = 1.08-2.25), and etanercept (adjusted RR = 1.34, 95% CI: 1.02-1.76) compared with methotrexate alone. Cyclosporine had a significant risk of serious infection (adjusted RR = 3.12, 95% CI = 1.1-8.8), followed by adalimumab combined with methotrexate (adjusted RR = 3.28, 95% CI = 0.8-13.5). Adalimumab in combination with methotrexate had the highest risk of infection recurrence (adjusted RR = 4.33, 95% CI = 2.27-8.24).
