[Immunsuppressive therapy in virus-negative eosinophilic inflammatory cardiomyopathy]
Deutsche Medizinische Wochenschrift (1946)
|April 14, 2011
Summary
This study shows that treating virus-negative eosinophilic inflammatory cardiomyopathy with prednisone and azathioprine can improve heart function and reduce heart failure symptoms. This therapy offers a promising approach for patients with this rare condition.
Area of Science:
- Cardiology
- Immunology
- Pathology
Background:
- Heart failure symptoms persisted in a 52-year-old woman despite guideline-based treatment.
- Coronary heart disease was previously excluded via coronary angiography.
Observation:
- Electrocardiography revealed sinus rhythm with decreased anterior wall amplitudes.
- Elevated white blood cells with eosinophilic granulocytes were noted.
- Echocardiography showed severe left ventricular dysfunction (ejection fraction 30%).
- Cardiac MRI indicated pathologic late enhancement in the left ventricular wall.
- Myocardial biopsies confirmed virus-negative eosinophilic inflammatory cardiomyopathy with focal fibrotic scarring.
Findings:
- Treatment with prednisone and azathioprine led to improved left ventricular ejection fraction from 30% to 45%.
- Clinical symptoms of heart failure resolved to NYHA II.
Implications:
- Standardized therapy with prednisone and azathioprine can be effective for virus-negative eosinophilic inflammatory cardiomyopathy.
- This treatment approach may improve left ventricular function and clinical outcomes in affected patients.

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...
01:29Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...
01:21Myocarditis I: Introduction
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
01:30Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
