About

Evaluating the long-term therapeutic effects and safety of hydroxychloroquine(compared to glucocorticoid therapy alone) in patients with inflammatory cardiomyopathy--a multicenter randomized controlled study

Full description

Inflammatory cardiomyopathy is the chronic stage of myocarditis, which is associated with poor cardiovascular outcome and poor prognosis.Inflammatory cardiomyopathy is also one of the common causes of heart failure. Actually, the treatment and prognosis of inflammatory cardiomyopathy remain challenging clinical issues that often have frustrating consequences. So far, there is no specific treatment for inflammatory cardiomyopathy. Hydroxychloroquine is a drug that can effectively inhibit inflammation and has been used in many inflammatory diseases in the past. Our previous basic research has proved that hydroxychloroquine can effectively treat experimental autoimmune myocarditis.Therefore, multicenter large randomized controlled trials are needed to verify the therapeutic effects of hydroxychloroquine on patients with inflammatory cardiomyopathy.

Patients with inflammatory cardiomyopathy after acute myocarditis confirmed by biopsy received standard drug treatment for heart failure. These patients whose cardiac function could not be improved for a long time were randomly assigned (1:1) to hydroxychloroquine group (hydroxychloroquine and glucocorticoid) and glucocorticoid group (glucocorticoid alone). The clinical benefit will be measured with respect to absolute increase in LVEF and decrease in hs-cTnI and NT-proBNP of immunosuppressive treatment with hydroxychloroquine and prednisolone compared to prednisolone alone at long-term follow-up (1, 3, 6, 9, 12, 18, 24, 36 months).
