title: Inhibition of TNFalpha does not induce viral reactivation in patients with chronic hepatitis C infection: two cases.
abstract: Chronic infections, such as hepatitis C, in the setting of rheumatic disorders pose a potential hindrance to optimal management because of possible complications linked to the institution of immune suppression, as well as the high incidence of hepatotoxicity associated with many of the disease-modifying antirheumatic drugs included in the conventional therapeutic regimens. In the setting of hepatitis C, however, the effect of TNFalpha blockade may be potentially beneficial because TNFalpha appears to be involved in the pathogenesis of liver fibrosis through the stimulation of apoptotic pathways. Data related to this subject are, unfortunately, still limited and without detailed information regarding the clinical progression of the rheumatic disorder. We report the cases of two patients, one with ankylosing spondylitis and one with psoriatic arthritis, who were efficiently treated long-term with anti-TNF agents for their rheumatic disease without any evidence of reactivation or flaring of their hepatitis C infection or deterioration of their liver function. Our results indicate that TNFalpha blockade is a highly efficient and uncompromising therapy in hepatitis C-affected individuals with connective tissue disorders. However, systematic, large-scale studies addressing the issue of safety of these new efficient drugs, i.e., monoclonal antibodies targeted against TNFalpha, in patients with chronic hepatitis C will be needed to properly assess the risks and benefits of this treatment in analogous cases.
