Objective There is little information regarding the incidence of bacterial infections as an adverse effect of telaprevir (TVR)-based triple therapy. This study was performed in order to evaluate the baseline and on-treatment predictors of bacterial infections in patients treated with TVR-based triple therapy.
Methods This multicenter study evaluated 430 patients with chronic hepatitis C who received 12 weeks of TVR in combination with 24 weeks of pegylated interferon α2b plus ribavirin. The occurrence of a bacterial infection during anti-viral treatment was defined as the onset of local or systemic inflammation as a result of pathogenic bacteria.
Results Bacterial infections occurred in 21 of the 430 (4.9%) patients during TVR-based triple therapy. Among these subjects, 71.4% (15 of 21) experienced bacterial infections during the initial eight weeks of treatment. Urinary tract infections were the most frequent infection, observed in 2.8% of cases (12 of 430). The rate of urinary tract infection among women (11 of 215, 5.1%) was significantly higher than that observed among men (1 of 215, 0.5%) (p<0.0001). According to a multivariable logistic regression analysis, the only significant independent predictor was the pretreatment serum albumin level (p=0.0008). Of the 21 patients who experienced bacterial infections, only one (4.8%) had to discontinue the treatment; however, the others were able to continue anti-viral treatment in combination with antibiotic treatment.
Conclusion Clinicians should be concerned regarding the incidence of bacterial infections among patients treated with TVR-based triple therapy, especially those with a low serum albumin level.
