RESUMO

Data on drug-drug interactions (DDI) of antineoplastic drugs with anticoagulants is scarce. We aim to evaluate factors associated with DDI of antineoplastic and supportive care drugs with anticoagulants resulting in modification of pharmacokinetics of these last mentioned. A literature review on DDI databases and summaries of products characteristics (SmPC) was done. Drug-drug interactions of 257 antineoplastic and supportive care drugs with direct oral anticoagulants (DOACs), warfarin, enoxaparin, or fondaparinux were categorized as no clinically significant expected DDI, potentially weak DDI, potentially clinically significant DDI, and recommendation against coadministration. Logistic regression models were performed to analyze the association between the dependent variable potentially clinically significant interaction/recommendation against coadministration and the mechanisms of DDI. Of the 1799 associations, 84.4% were absence of DDI, 3.6% potentially weak DDI, 10.2% potentially clinically relevant DDI, and 2.0% recommendation against coadministration. Warfarin has higher DDI potential than other anticoagulants. Enoxaparin and fondaparinux have fewer DDI than others. There was no difference between DOACs. Drug-drug interactions with apixaban and rivaroxaban was independently associated with the absence of CYP3A4 competition, P-glycoprotein inhibition, CYP3A4 induction, and drug class of tyrosine kinase inhibitors. Drug-drug interactions with dabigatran and edoxaban was associated with inhibition of P-glycoprotein and tyrosine kinase inhibitors. Warfarin, induction of CYP3A4, and inhibition of CYP2C9. Enoxaparin and fondaparinux, only tyrosine kinase inhibitors. Direct oral anticoagulants did not differ regarding DDI with antineoplastic agents. Warfarin presented more DDI than other anticoagulants. P-glycoprotein inhibition and CYP3A4 induction were independently associated with DDI of antineoplastic agents with DOACs.

RESUMO

This manuscript summarizes the results of the consensus meeting composed of hematologists and cardiologists to establish recommendations for the prevention and follow-up of cardiovascular (CV) risk in patients with chronic myeloid leukemia (CML) treated with BCR-ABL tyrosine kinase inhibitors (TKIs) from the point of view of clinical practice and from the perspective of hematology consultation. In the first medical appointment, the CV risk factors should be identified to perform the baseline risk stratification, based on the Brazilian Guideline of Dyslipidemia and Atherosclerosis Prevention Update (risk levels: very high, high, intermediate and low). Once stratified, the treatment of the CV risk factors should be administered. If the patient presents risk factors, such as hypertension, diabetes, renal disease, smoking and hypercholesterolemia, the evaluation and initial treatment may be done by the hematologist, being an option the request for evaluation by a specialist. If the patient has a history of previous CV disease, we recommend referral to a specialist. As the CV risk score is dynamic and the control of risk factors can reduce the patient risk, this expert consensus recommends that the re-evaluation of the CV risk after the baseline should be performed at 3 months, 6 months and 12 months. After this period, it should be done annually and, for specific patients, at the clinician's discretion. The evaluation of the baseline CV risk and the safe administration of a TKI allow the patient to benefit from the maximum treatment, avoiding unwanted effects.

RESUMO

Angiotensin-converting enzyme-2 (ACE2) expression may increase due to upregulation in patients using angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARBs). Because renin-angiotensin system blockers increase levels of ACE2, a protein that facilitates coronavirus entry into cells, there is concern that these drugs could increase the risk of developing a severe and fatal form of COVID-19. The impact of discontinuing ACEI and ARBs in patients with COVID-19 remains uncertain. DESIGN: BRACE CORONA is a pragmatic, multicenter, randomized, phase IV, clinical trial that aims to enroll around 500 participants at 34 sites in Brazil. Participants will be identified from an ongoing national registry of suspected and confirmed cases of COVID-19. Eligible patients using renin-angiotensin system blockers (ACEI/ARBs) with a confirmed diagnosis of COVID-19 will be randomized to a strategy of continued ACEI/ARB treatment versus temporary discontinuation for 30 days. The primary outcome is the median days alive and out of the hospital at 30 days. Secondary outcomes include progression of COVID-19 disease, all-cause mortality, death from cardiovascular causes, myocardial infarction, stroke, transient ischemic attack, new or worsening heart failure, myocarditis, pericarditis, arrhythmias, thromboembolic events, hypertensive crisis, respiratory failure, hemodynamic decompensation, sepsis, renal failure, and troponin, B-type natriuretic peptide (BNP), N-terminal-proBNP, and D-dimer levels. SUMMARY: BRACE CORONA will evaluate whether the strategy of continued ACEI/ARB therapy compared with temporary discontinuation of these drugs impacts clinical outcomes among patients with COVID-19.

RESUMO

OPINION STATEMENT: Cardiac amyloidosis is associated with a high mortality rate, a long delay between the first signs and the diagnosis but a short interval between diagnosis and death. This scenario has changed recently due to improved disease awareness among doctors and significant progress in diagnosis thanks to multimodal imaging and a multidisciplinary approach. Therefore, during the last few years, we have had access to specific therapies for those patients. Those therapies are quite different depending on the type of amyloidosis, but there has been real progress. Systemic light chain amyloidosis (AL) with cardiac involvement is the most common form of cardiac amyloidosis. The severity of heart disease dictates the prognosis in AL amyloidosis. Advances in chemotherapy and immunotherapy that suppress light chain production have improved the outcomes. These recent improvements in survival rates have enabled therapies such as implanted cardiac defibrillators and heart transplantation that were usually not indicated for patients with advanced light chain amyloid cardiomyopathy to now be applied in selected patients. For transthyretin amyloidosis (ATTR), the second most common form of amyloidosis with cardiac involvement, there is also significant progress in treatment. Until recently, we had no specific therapy for ATTR cardiomyopathy (ATTR-CM), though now disease-modifying therapies are available. Therapies that stabilize transthyretin, such as tafamidis, have been shown to improve outcomes for patients with ATTR-CM. Modern treatments that stop the synthesis of TTR through gene silencing, such as patisiran and inotersen, have shown positive results for patients with TTR amyloidosis. Significant progress has been made in the treatment of amyloid cardiomyopathy, and hopefully, we will see even more progress with the spread of those treatments. We now can be optimistic about patients with this disease.

RESUMO

Abstract Background: Chemotherapeutic agents of anthracyclines class and humanized monoclonal antibodies are effective treatments for breast cancer, however, they present a potential risk of cardiotoxicity. Several predictors have been recognized as predictors in the development of cardiac toxicity, and the evaluation of left ventricular segmental wall motion abnormalities (LVSWMA) has not been studied. Objective: To analyze prospectively the role of LVSWMA among echocardiographic parameters in the prediction of development of cardiotoxicity in breast cancer patients undergoing treatment with chemotherapy. Methods: Prospective cohort of patients diagnosed with breast cancer and in chemotherapy treatment with potential cardiotoxicity medications including doxorubicin and trastuzumab. Transthoracic echocardiograms including speckle tracking strain echocardiography were performed at standard times before, during and after the treatment to assess the presence (or lack thereof) of cardiotoxicity. Cardiotoxicity was defined by a 10% decrease in the left ventricular ejection fraction, on at least one echocardiogram. Multivariate logistic regression models were used to verify the predictors related to the occurrence of cardiotoxicity over time. Results: Of the 112 patients selected (mean age 51,3 ± 12,9 years), 18 participants (16.1%) had cardiotoxicity. In the multivariate analysis using the logistic regression model, those with LVWMA (OR = 6.25 [CI 95%: 1.03; 37.95], p < 0,05), LV systolic dimension (1.34 [CI 95%: 1.01; 1.79], p < 0,05) and global longitudinal strain by speckle tracking (1.48 [CI 95%: 1.02; 2.12], p < 0,05) were strongly associated with cardiotoxicity. Conclusion: In the present study, we showed that LVWMA, in addition to global longitudinal strains, were strong predictors of cardiotoxicity and could be useful in the risk stratification of these patients.


Resumo Fundamento: Os agentes quimioterápicos da classe das antraciclinas e dos anticorpos monoclonais humanizados são tratamentos eficazes para o câncer de mama, entretanto, apresentam alto risco de cardiotoxicidade. Diversos parâmetros têm sido reconhecidos como preditores no desenvolvimento de toxicidade cardíaca, sendo que a avaliação da alteração contrátil segmentar ventricular esquerda (ACSVE) ainda não foi estudada. Objetivo: Analisar a associação entre o surgimento de ACSVE e o desenvolvimento de cardiotoxicidade em pacientes com câncer de mama em tratamento com quimioterapia. Métodos: Coorte prospectiva de pacientes diagnosticados com câncer de mama e em tratamento quimioterápico com doxorrubicina e/ou trastuzumab. Foram realizados ecocardiogramas transtorácicos antes, durante e depois do tratamento para avaliar a presença ou não de cardiotoxicidade. A cardiotoxicidade foi definida por um decréscimo de 10% na fração de ejeção do ventrículo esquerdo, em pelo menos um ecocardiograma. Modelos de regressão logística multivariada foram utilizados para verificar os fatores preditores na ocorrência de cardiotoxicidade ao longo do tempo. Resultados: Dos 112 pacientes selecionados (idade média = 51,3 ± 12,9 anos), 18 (16,1%) apresentaram cardiotoxicidade. Na análise multivariada os pacientes com ACSVE (OR = 6,25 [IC 95%: 1,03; 37,95], p < 0,05), diâmetro sistólico do VE (OR = 1,34 [IC 95%:1,01; 1,79], p < 0,05) e strain longitudinal global pela técnica de speckle tracking (OR = 1,48 [IC 95%: 1,02; 2,12], p < 0,05) foram preditores significativos e independentes na predição de cardiotoxidade. Conclusão: Mostramos que ACSVE, bem como a redução do strain longitudinal global foram preditores independentes para cardiotoxicidade, podendo ser úteis na estratificação de risco destes pacientes.

RESUMO

Breast cancer is the most frequently diagnosed tumor in women worldwide, with a significant impact on morbidity and mortality. Chemotherapy and hormone therapy have significantly reduced mortality; however, the adverse effects are significant. Aspirin has been incorporated into clinical practice for over 100 years at a low cost, making it particularly attractive as a potential agent in breast cancer prevention and as an adjunct treatment to endocrine therapy in the prophylaxis of cardiovascular complications. The objective of this study was to evaluate the role of aspirin in reducing the incidence of breast cancer and to evaluate the impact of its use on morbidity and mortality and reduction of cardiovascular events as adjuvant therapy during breast cancer treatment with selective estrogen receptor modulators. A systematic review was performed using the PRISMA methodology and PICO criteria, based on the MEDLINE, EMBASE and LILACS databases. The original articles of clinical trials, cohort, case-control studies and meta-analyses published from January 1998 to June 2017, were considered. Most studies showed an association between the use of selective estrogen receptor modulators and the increase in thromboembolic events. The studies suggest a protective effect of aspirin for cardiovascular events during its concomitant use with selective estrogen receptor modulators and in the prevention of breast cancer. This systematic review suggests that aspirin therapy combines the benefit of protection against cardiovascular events with the potential reduction in breast cancer risk, and that the evaluation of the benefits of the interaction of endocrine therapy with aspirin should be further investigated.

Resumo O câncer de mama é o tumor mais frequentemente diagnosticado em mulheres de todo o mundo, com impacto importante na morbimortalidade. A quimioterapia e a terapia hormonal reduziram significativamente a mortalidade, mas os efeitos adversos são consideráveis. A aspirina está incorporada à prática clínica há mais de 100 anos, com baixo custo, tornando-a particularmente atraente como potencial agente na prevenção do câncer de mama e auxiliar durante o tratamento endócrino, na profilaxia de complicações cardiovasculares. Objetivou-se avaliar o papel da aspirina na redução da incidência do câncer de mama e avaliar o impacto de seu uso na morbimortalidade e na redução de eventos cardiovasculares como terapia adjuvante durante o tratamento do câncer de mama com moduladores seletivos do receptor do estrogênio. Procedeu-se à revisão sistemática utilizando-se a metodologia PRISMA e os critérios PICO, nas bases MEDLINE, EMBASE e LILACS. Foram considerados os artigos originais do tipo ensaio clínico, coorte, caso-controle e metanálises, publicados no período de janeiro de 1998 até junho de 2017. Na maioria dos estudos, houve relação entre o uso dos moduladores seletivos do receptor do estrogênio e o aumento de eventos tromboembólicos. Os estudos sugerem efeito protetor da aspirina para eventos cardiovasculares em uso concomitante aos moduladores seletivos do receptor do estrogênio e na prevenção do câncer de mama. Esta revisão sistemática sugere que o tratamento com aspirina combina o benefício da proteção contra eventos cardiovasculares com a potencial redução do risco de câncer de mama, e que a avaliação dos benefícios da interação da terapia endócrina com a aspirina deve ser melhor investigada.

RESUMO

O primeiro passo para a prevenção de cardiotoxicidade é avaliar o indivíduo quanto ao risco cardiovascular basal e identificar os pacientes de alto risco. É essencial a abordagem proativa, otimizando o tratamento das doenças cardiovasculares existentes e reduzindo os fatores que contribuem para o aumento do risco cardiovascular. Essa avaliação é um processo contínuo, que deve acontecer durante todo o tratamento. Nos pacientes candidatos a altas doses de antraciclina, algumas estratégias possíveis para mitigar a cardiotoxicidade são o uso de infusão contínua de antraciclina em vez de infusão em bolus, uso de doxorrubicina lipossomal em substituição a doxorrubicina tradicional e uso de dexrazoxano antes da infusão de antracíclico. As evidências atuais ainda não corroboram o uso rotineiro de bloqueadores neuro-hormonais ou estatinas como agentes cardioprotetores em todos os pacientes tratados com quimioterapia potencialmente cardiotóxica


he first step in preventing cardiotoxicity is to evaluate the baseline cardiovascular risk in the individual, and to identify high-risk patients. A proactive approach is essential, optimizing the treatment of existing cardiovascular patients and reducing the factors that contribute to the increase in cardiovascular risk. This evaluation is a continuous process that should occur throughout the treatment. In candidate patients for high-dose anthracycline, some possible strategies to mitigate cardiotoxicity are the use of continuous anthracycline infusion instead of as a bolus, the use of liposomal doxorubicin to replace traditional doxorubicin, and the use of dexrazoxane prior to anthracycline infusion. Current evidence does not support the routine use of neurohormonal blockers or statins as cardioprotective agents in all patients treated with potentially cardiotoxic chemotherapy
