Case reportSpecific cardiomyopathy in lupus patients: report of three cases
Introduction
Cardiac involvement in systemic lupus erythematosus (SLE) is well known. Cardiac manifestations of SLE include pericarditis, myocarditis, valvular disease, ischemic coronary artery disease, conduction abnormalities, arrhythmias. Although myocardial abnormalities are frequent in autopsic studies, clinically patent myocarditis occurs in less than 10% of patients [1]. We describe three patients with SLE seen over a 1 year period, who presented with rapid onset of left ventricular dysfunction (Table 1).

Patient 1
A 43-year-old woman with a history of longstanding Raynaud’s phenomenon presented with polyarthralgias and myalgias. Initial examination showed synovitis in both wrists and fingertips.
Laboratory tests revealed a strongly positive antinuclear antibody (ANA) at 1:1280 with presence of anti-Sm and anti-RNP antibodies. Anti-dsDNA were negative. Signs of vasculitis were present on muscular biopsy. SLE was diagnosed and treatment with prednisone 20 mg per day and hydroxychloroquine 400 mg per day was
Discussion
Severe myocardial dysfunctions are uncommon during SLE, and most often associated with coronary atherosclerosis, longstanding hypertension and corticotherapy. We report three cases of cardiomyopathy with congestive heart failure, in the absence of hypertensive coronary artery disease, characterized by their early occurrence in the course of the lupus disease. Two of these cases, who were treated with high-dose corticotherapy had a significant improvement of the left ventricular function. The

Dilated cardiomyopathy complicated by an intracavitary thrombus and acute heart failure: A rare presentation of systemic lupus erythematosus
2022, Annals of Medicine and SurgeryCitation Excerpt :The exact pathogenesis of myocardial involvement is not entirely understood [13]. Case reports of SLE patients with cardiac manifestations who had undergone myocardial biopsy lack evidence for myocarditis [3,14]. This suggest that myocardial inflammation may not be the pathophysiological basis, and that other factors such as thrombotic or inflammatory microvascular coronary disease may play a role [15].
The use of glucocorticoids in Systemic Lupus Erythematosus. After 60years still more an art than science
2013, Autoimmunity ReviewsCitation Excerpt :Oral prednisone dose ranges from 30 mg to 1 mg/kg in both groups with the lower dosages in the pericarditis group (about 30 mg) and higher dosage in myocarditis (about 1 mg/kg). Most publications report a high response rate (defined by normalization of ejection fraction and/or resolution of pericardial effusion) [96–111]. Treatment of pulmonary manifestations with GCs is scarcely published in the literature.
Multimodality imaging and the emerging role of cardiac magnetic resonance in autoimmune myocarditis
2012, Autoimmunity ReviewsCitation Excerpt :Favorable response to cyclophosphamide or azathioprine, following as a steroid sparing agent, has also been reported [97]. The administration of intravenous immunoglobulin in severely ill patients with lupus myocarditis refractory to steroids has shown good clinical outcome with rapid recovery and resolution of left ventricular abnormalities in small series of patients [98,99]. It has been suggested that IVIG prevents humoral immunity induced myocyte damage through its anti-idiotypic properties and diminishes the expression and the synthesis of TNF-alpha, IL-6 and other proinflammatory cytokines [100].
