Autoimmune hepatitis and anti-tumor necrosis factor alpha therapy: A single center report of 8 cases.

This article describes cases of anti-tumor necrosis factor (TNF)-α-induced autoimmune hepatitis and evaluates the outcome of these patients in relation to their immunosuppressive strategy. A retrospective analysis of medical records was performed in our center, in order to detect cases of autoimmune hepatitis (AIH) associated with anti-TNF biologic agents. We describe and analyze eight cases of AIH following anti-TNF therapy, 7 with infliximab and 1 with adalimumab. A distinction should be made between induction of autoimmunity and clinically evident autoimmune disease. Liver biopsy is useful in detecting the role of the TNF-α antagonist in the development of AIH. The lack of relapse after discontinuing immunosuppressive therapy favors, as in this case series, an immune-mediated drug reaction as most patients with AIH have a relapse after treatment is suspended. Although AIH related to anti-TNF therapy is rare, a baseline immunological panel along with liver function tests should be performed in all patients with autoimmune disease before starting biologics.

Management of autoimmune hepatitis: Focus on pharmacologic treatments beyond corticosteroids.

In autoimmune hepatitis, patients who are intolerant or with toxicity experience, non-responders, relapsers or refractory are challenging. Non-standard drugs are being tried to preemptively avoid corticosteroid-related side effects. Prognosis and quality of life of life rely on treatment optimization. Recently, emergence of powerful immunosuppressive agents, mainly from liver transplantation, challenged the supremacy of the corticosteroid regime and promise greater immunosuppression than conventional medications, offer site-specific actions and satisfactory patient tolerance. Successes in experimental models of related diseases have primed these molecular interventions. We performed a literature review on alternative treatments. Azatioprine intolerance is the principal indication for mycophenolate use but it can be used as a front-line therapy. Cyclosporine A and tacrolimus have been tested for non-responders or relapsers. Rituximab may be used as salvage therapy. Anti-tumor necrosis factor-alpha agents may be used for incomplete responses or non-responders. Methotrexate is possibly an alternative for induction of remission and maintenance in refractory patients. Cyclophosphamide has been included in the induction regimen with corticosteroids. Ursodeoxycholic acid action is mainly immunomodulatory. Non-standard treatments are coming slowly to the attention, but its use should be cautious performed by experienced centers.

The impact of peginterferon alfa-2a plus ribavirin combination therapy on health-related quality of life in chronic hepatitis C.

BACKGROUND/AIMS: Peginterferon alfa-2a plus ribavirin improves sustained virological responses compared with interferon alfa-2b and ribavirin, or peginterferon alfa-2a alone in chronic hepatitis C. We examined the impact of these treatments on health related quality of life (HRQOL). METHODS: Patients (n=1121) were randomized to peginterferon alfa-2a weekly plus ribavirin or placebo, or interferon alfa-2b thrice weekly plus ribavirin. HRQOL was assessed with the SF-36 Health Survey and Fatigue Severity Scale (FSS). RESULTS: Patients receiving peginterferon alfa-2a plus ribavirin reported better HRQOL than those receiving interferon alfa-2b plus ribavirin. These differences were statistically significant for three SF-36 domains and both FSS scores (p<=0.05). Patients receiving peginterferon alfa-2a plus placebo had the least impairment; adding ribavirin significantly decreased five domains of the SF-36 and both FSS scores. Sustained virological response was associated with improvement at follow-up on all SF-36 and FSS scores. CONCLUSIONS: The effects of combination therapy on HRQOL and fatigue are less with peginterferon alfa-2a plus ribavirin than interferon alfa-2b plus ribavirin. Each medication in combination therapy with interferon and ribavirin, affects patients' quality of life differently. Understanding the relationship of specific therapeutic options to HRQOL may help physicians minimize the impact of therapy on HRQOL.
