Partially Reversible Cardiomyopathy after Renal Transplant Associated with Anti-Troponin I Antibodies

Abstract: Cardiomyopathy associated with dialysis has been shown to be reversible in some cases. A 58-year-old female patient with polycystic renal disease and end-stage renal disease had a renal transplant after 9 years on hemodialysis. Dilated cardiomyopathy with depressed left ventricular ejection fraction markedly improved after transplantation, with normalization of the ejection fraction. High titers for anti-troponin I antibodies were measured: IgG 1:640, IgM 1:80. In our case, the presence of anticardiac (anti-tr… Show more

“…Following renal transplantation, a significant improvement in systolic function has been observed in these patients [79,80]. In a recent publication, Nunes et al describe a case of reversible cardiomyopathy in a patient with a high titre of ATIAs undergoing a renal transplant [81]. Although conjectural, they proposed that this improvement might have resulted from posttransplant suppression of an autoimmune response directed against cardiac troponin.…”

“…Em 2013 este mesmo grupo relatou um caso clínico de uma doente de género feminino com miocardiopatia dilatada e fração de ejeção de 30%, a qual, após transplantação renal, evidenciou uma recuperação da função ventricular, apesar de não ter regredido o seu volume telediastólico 10 . Nesta doente foram ainda encontrados valores muito elevados de anticorpos antitroponina I (IgG 1:640 e IgM 1:80), o que provavelmente terá estimulado a continuidade da investigação.…”
