D. C.; AVILA, M.; BISELI, B.; AYUB, S. F.; BACAL, F.; BOCCHI, E. A.- The first cardiac transplant experience in a patient with mucopolysaccharidosis(2012) GRINBERG, Henrique; QUAIO, Caio Robledo D'Angioli Costa; AVILA, Monica Samuel; FERREIRA, Silvia Moreira Ayub; VIEIRA, Marcelo Luiz Campos; BENVENUTI, Luiz Alberto; KIM, Chong Ae; BOCCHI, Edimar AlcidesHunter syndrome (MPSII) is a rare X-linked lysosomal storage disorder that can affect multiple systems but primarily affects the heart. We report the case of a previously asymptomatic 23-year-old patient who had an attenuated form of MPSII and presented with refractory heart failure that required a heart transplant. The diagnosis was confirmed by detection of an increase in urinary excretion of glycosaminoglycans, a deficiency in enzymatic activity, and molecular analysis. A myocardial biopsy revealed hypertrophic cardiomyocytes, mild fibrosis, and lysosomal storage in interstitial cells. Molecular analysis identified a novel mutation in the iduronate-2-sulfatase gene. Although the clinical outcome was not favorable, we believe that this approach may be valid in end-stage heart failure.
- Circulating miR-1 as a potential biomarker of doxorubicin-induced cardiotoxicity in breast cancer patients(2017) RIGAUD, Vagner Oliveira-Carvalho; FERREIRA, Ludmila R. P.; AYUB-FERREIRA, Silvia M.; AVILA, Monica S.; BRANDAO, Sara M. G.; CRUZ, Fatima D.; SANTOS, Marilia H. H.; CRUZ, Cecilia B. B. V.; ALVES, Marco S. L.; ISSA, Victor S.; GUIMARAES, Guilherme V.; CUNHA-NETO, Edecio; BOCCHI, Edimar A.Cardiotoxicity is associated with the chronic use of doxorubicin leading to cardiomyopathy and heart failure. Identification of cardiotoxicity-specific miRNA biomarkers could provide clinicians with a valuable prognostic tool. The aim of the study was to evaluate circulating levels of miRNAs in breast cancer patients receiving doxorubicin treatment and to correlate with cardiac function. This is an ancillary study from ""Carvedilol Effect on Chemotherapy-induced Cardiotoxicity"" (CECCY trial), which included 56 female patients (49.9 +/- 3.3 years of age) from the placebo arm. Enrolled patients were treated with doxorubicin followed by taxanes. cTnI, LVEF, and miRNAs were measured periodically. Circulating levels of miR-1,-133b,-146a, and -423-5p increased during the treatment whereas miR-208a and -208b were undetectable. cTnI increased from 6.6 +/- 0.3 to 46.7 +/- 5.5 pg/mL (p<0.001), while overall LVEF tended to decrease from 65.3 +/- 0.5 to 63.8 +/- 0.9 (p=0.053) over 12 months. Ten patients (17.9%) developed cardiotoxicity showing a decrease in LVEF from 67.2 +/- 1.0 to 58.8 +/- 2.7 (p=0.005). miR-1 was associated with changes in LVEF (r=-0.531, p<0.001). In a ROC curve analysis miR-1 showed an AUC greater than cTnI to discriminate between patients who did and did not develop cardiotoxicity (AUC = 0.851 and 0.544, p = 0.0016). Our data suggest that circulating miR-1 might be a potential new biomarker of doxorubicin-induced cardiotoxicity in breast cancer patients.

Prevention with beta-blockers remains controversial. OBJECTIVES This prospective, randomized, double-blind, placebo-controlled study sought to evaluate the role of carvedilol in preventing ANT cardiotoxicity. METHODS The authors randomized 200 patients with HER2-negative breast cancer tumor status and normal left ventricular ejection fraction (LVEF) referred for ANT (240 mg/m(2)) to receive carvedilol or placebo until chemotherapy completion. The primary endpoint was prevention of a >= 10% reduction in LVEF at 6 months. Secondary outcomes were effects of carvedilol on troponin I, B-type natriuretic peptide, and diastolic dysfunction. RESULTS Primary endpoint occurred in 14 patients (14.5%) in the carvedilol group and 13 patients (13.5%) in the placebo group (p = 1.0). No differences in changes of LVEF or B-type natriuretic peptide were noted between groups. A significant difference existed between groups in troponin I levels over time, with lower levels in the carvedilol group (p = 0.003). Additionally, a lower incidence of diastolic dysfunction was noted in the carvedilol group (p = 0.039). A nonsignificant trend toward a less-pronounced increase in LV end-diastolic diameter during the follow-up was noted in the carvedilol group (44.1 +/- 3.64 mm to 45.2 +/- 3.2 mm vs. 44.9 +/- 3.6 mm to 46.4 +/- 4.0 mm; p = 0.057). CONCLUSIONS In this largest clinical trial of beta-blockers for prevention of cardiotoxicity under contemporary ANT dosage, the authors noted a 13.5% to 14.5% incidence of cardiotoxicity. In this scenario, carvedilol had no impact on the incidence of early onset of LVEF reduction. However, the use of carvedilol resulted in a significant reduction in troponin levels and diastolic dysfunction.(Carvedilol Effect in Preventing Chemotherap-Induced Cardiotoxicity [CECCy] NCTO1724450)(C) 2018 by the American College of Cardiology Foundation.
