OBJECTIVES: Antiviral treatment with pegIFN/RBV decreases ANC and CD4+ cell count. An association between neutropenia, a low CD4+ cell count and infections has not been demonstrated so far in HIV-HCV coinfected patients. METHODS: The incidence, type, and severity of infections were recorded in 85 HIV-HCV coinfected and 164 monoinfected patients receiving pegIFN/RBV for 48 weeks. ANC and CD4+ cell count were assessed every 4 weeks during therapy. RESULTS: The incidence of infections was significantly higher in HIV-HCV than HCV-Mono (38% vs. 15%; p = 0.001). Types of infections: pneumonia (n = 16/n = 24), bacteraemia/sepsis (n = 5/n = 2), skin infections (n = 15/n = 12), urinary tract infections (n = 4/n = 1), OIs (n = 10/n = 1). The incidence of neutropenia grade 1, 2 3 or 4 was similar in HIV-HCV and HCV-Mono, respectively. The incidence of infections was not associated with neutropenia (HCV-Mono: p = 0.584; HIV-HCV: p = 0.23) or with CD4+ cell counts <200/μL (HIV-HCV: p = 0.29). OIs occurred more often in HIV-HCV patients with CD4+ cell count <200/μL (p = 0.024). CONCLUSIONS: Up to 38% and 15% of HIV-HCV coinfected and HCV-monoinfected patients develop infections during pegIFN+RBV therapy but without any correlation to neutropenia. Antibacterial prophylaxis/treatment should be considered early in HIV-HCV coinfected patients developing CD4+ cell counts <200/μL during antiviral therapy as these patients have an increased risk of OIs.
