Immunomodulating and Immunosuppressive Therapy for Virus-Negative Immune-Mediated Myocarditis

Area of Science:

• Cardiology
• Immunology
• Pathology

Background:

• Myocarditis is myocardial inflammation from diverse triggers, presenting a diagnostic and therapeutic challenge due to variable clinical courses.
• Current treatment strategies for myocarditis are not standardized, particularly for virus-negative lymphocytic myocarditis.

Purpose of the Study:

• To review the role of immunomodulating and immunosuppressive therapies in immune-mediated myocarditis.
• To outline treatment strategies tailored to the specific etiology of myocarditis.

Main Methods:

• Review of existing literature on myocarditis and its treatments.
• Analysis of the efficacy of immunosuppressive therapies in various myocarditis subtypes.
• Emphasis on the diagnostic role of endomyocardial biopsy for personalized treatment.

Main Results:

• Immunosuppression is established for specific myocarditis types (e.g., sarcoidosis, eosinophilic, giant-cell, drug hypersensitivity, trauma-related, connective tissue disease-associated, transplant rejection).
• Immunosuppressive therapy shows promise in virus-negative inflammatory cardiomyopathy.
• Endomyocardial biopsy is crucial for accurate diagnosis and guiding targeted therapy.

Conclusions:

• Immunomodulating and immunosuppressive therapies are vital for managing immune-mediated myocarditis.
• Treatment decisions must be individualized based on etiological factors identified through biopsy.
• Further research is needed to refine treatment protocols for challenging myocarditis cases.
