Acute viral myocarditis triggers an autoimmune phenomenon that aggressive immunosuppressive therapy with monoclonal OKT3 may suppress. We treated 5 patients, aged 15 months to 16.5 years, who had acute viral myocarditis and left ventricular ejection fraction (LVEF) of 5% to 20%, with a combination immunosuppressive regimen that included OKT3, intravenous immunoglobulin, methylprednisone, cyclosporine, and azathioprine. Within 2 weeks of therapy, all patients demonstrated normalization of LVEF to 50% to 74%, and on mid-term follow-up, we have found no recurrence of heart failure or progression to dilated cardiomyopathy. In patients with severe acute myocarditis, aggressive immunosuppressive regimen based on OKT3 is safe and may inhibit or reverse the immune response, resulting in dramatic improvement in myocardial function.

UI MeSH Term Description Entries
D007166 Immunosuppressive Agents Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.

D009205 Myocarditis Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies. Carditis,Myocarditides

D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
