Clinical Management of Long-Term Survivors after Classical Hodgkin Lymphoma and Diffuse Large B-Cell Lymphoma.

Compared to other patients suffering from hematological malignancies, classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) patients have a long life expectancy when in complete remission at the end of first, or sometimes second, line treatments [...].

Cancer-Associated Thrombosis: Not All Low-Molecular-Weight Heparins Are the Same, Focus on Tinzaparin, A Narrative Review.

Cancer-associated thrombosis (CAT) is the second main cause of cancer death with high related mortality and morbidity, leading to anticancer agent delays and interruptions. The recommended therapy, low-molecular-weight heparin (LMWH), however, is burdensome for patients and costly for society, as treatment should last until cancer is no longer active, even indefinitely. Tinzaparin is a manageable, efficient, safe, and cost-effective option. Compared to the other LMWHs, advantages are single-daily dose and safety in the elderly and those with renal impairment (RI). The purpose of this review is to critically discuss recent data on its efficacy and safety in CAT.

Edoxaban: front-line treatment for brachiocephalic vein thrombosis in primitive mediastinal seminoma: A case report and literature review.

RATIONALE: Venous thromboembolism is a feared frequent complication of cancer with a 2-way relationship. Low molecular weight heparin is the mainstay of treatment. The use of direct oral anticoagulants is supported by established evidence for the treatment of deep vein thrombosis also in active cancer and they are prioritized over low molecular weight heparin for cancer-associated thrombosis according to current guidelines. However, upper limb deep vein thrombosis is poorly studied with scant data on the use of direct oral anticoagulants in noncatheter-related deep vein thrombosis. We report the case of a patient with noncatheter-related deep vein thrombosis and a rare tumor site effectively and safely treated with a direct oral anticoagulant, edoxaban, after lack of efficacy with low molecular weight heparin. PATIENT CONCERNS: A 35-year-old man with primitive mediastinal seminoma presented at our Cardio-Oncology Unit for prechemotherapy assessment. DIAGNOSIS: Persistent brachiocephalic deep vein thrombosis, despite full-dose enoxaparin, was detected at ultrasonography. INTERVENTION: We decided to switch the anticoagulant treatment from enoxaparin to edoxaban. OUTCOME: The 3-month ultrasonography showed almost total regression of the deep vein thrombosis without any adverse effects and a good patient compliance. LESSONS: We conducted a literature review on upper limb deep vein thrombosis, since its management is challenging due to inconsistency of evidence. This report highlights the benefits of direct oral anticoagulants compared to low molecular weight heparins in cancer-associated thrombosis therapy in terms of efficacy, safety and ease of use.

Echocardiography Monitoring during Anthracycline Administration in Hodgkin and Non-Hodgkin's Lymphoma: The Tei Index Evaluation.

Anthracyclines are widely employed in lymphoma's chemotherapy and has been shown to induce heart failure. Echocardiographic parameters of left ventricular (LV) systolic function are usually used to monitor the cardiac side effects during and after anthracyclines treatment. The measurement of theTei index could anticipate the onset of LV dysfunction. The aim of this study was to evaluate the performance of the delta Tei index for the early detection of cardiac toxicity in a prospective population of anthracycline-treated lymphoma patients. Our preliminary data suggest that the Tei index may predict the risk for cardiotoxicity in this subset of patients earlier than LV ejection fraction alteration.

Late Cardiological Sequelae and Long-Term Monitoring in Classical Hodgkin Lymphoma and Diffuse Large B-Cell Lymphoma Survivors: A Systematic Review by the Fondazione Italiana Linfomi.

Cardiotoxicity represents the most frequent cause with higher morbidity and mortality among long-term sequelae affecting classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) patients. The multidisciplinary team of Fondazione Italiana Linfomi (FIL) researchers, with the methodological guide of Istituto di Ricerche Farmacologiche "Mario Negri", conducted a systematic review of the literature (PubMed, EMBASE, Cochrane database) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, in order to analyze the following aspects of cHL and DLBCL survivorship: (i) incidence of cardiovascular disease (CVD); (ii) risk of long-term CVD with the use of less cardiotoxic therapies (reduced-field radiotherapy and liposomal doxorubicin); and (iii) preferable cardiovascular monitoring for left ventricular (LV) dysfunction, coronary heart disease (CHD) and valvular disease (VHD). After the screening of 659 abstracts and related 113 full-text papers, 23 publications were eligible for data extraction and included in the final sample. There was an increased risk for CVD in cHL survivors of 3.6 for myocardial infarction and 4.9 for congestive heart failure (CHF) in comparison to the general population; the risk increased over the years of follow-up. In addition, DLBCL patients presented a 29% increased risk for CHF. New radiotherapy techniques suggested reduced risk of late CVD, but only dosimetric studies were available. The optimal monitoring of LV function by 2D-STE echocardiography should be structured according to individual CV risk, mainly considering as risk factors a cumulative doxorubicine dose >250 mg per square meter (m2) and mediastinal radiotherapy >30 Gy, age at treatment <25 years and age at evaluation >60 years, evaluating LV ejection fraction, global longitudinal strain, and global circumferential strain. The evaluation for asymptomatic CHD should be offered starting from the 10th year after mediastinal RT, considering ECG, stress echo, or coronary artery calcium (CAC) score. Given the suggested increased risks of cardiovascular outcomes in lymphoma survivors compared to the general population, tailored screening and prevention programs may be warranted to offset the future burden of disease.

Right Ventricular Longitudinal Strain Measures Independently Predict Chronic Heart Failure Mortality.

The assessment of right ventricular (RV) function still remains a challenge. Two-dimensional (2D) speckle tracking has recently been proposed to evaluate right ventricular function by analyzing myocardial deformation. The aim of this study was to evaluate the role of 2D systolic strain measures of RV in predicting mortality in patients with chronic heart failure (HF). We enrolled 332 outpatients in a stable clinical condition and in conventional therapy. A right ventricular-focused four-chamber view was analyzed by 2D speckle tracking to evaluate the global longitudinal strain of RV (RV-GLS) and the strain of RV free wall (RV-fwLS). During a mean follow-up of 36 ± 26 months, 64 patients died. Both RV-GLS and RV-fwLS were associated with all-cause mortality in univariate (HR: 1.16; 95% CI: 1.10-1.23; P < 0.001; C-index: 0.72; and HR: 1.10; 95% CI: 1.06-1.15; P < 0.001; C-index: 0.68, respectively) as well as multivariate analysis (HR: 1.13; 95% CI: 1.05-1.21; P:0.001; C-index: 0.85; and HR: 1.07; 95% CI: 1.02-1.12; P:0.004; C-index: 0.84, respectively). In conclusion, our findings demonstrate the role of RV 2D strain measures to independently predict mortality. These data highlight the clinical usefulness of this echocardiographic approach in the daily management of HF outpatients.

Incidence and prevalence of hypothyroidism in patients affected by chronic heart failure: role of amiodarone.

BACKGROUND: It has been demonstrated that hypothyroidism can lead to significant hemodynamic alterations favoring the onset of chronic heart failure (CHF) as well as its progression. Furthermore, amiodarone, an iodine-containing antiarhythmic drug frequently used in CHF patients, is often the cause of primary hypothyroidism. AIM OF THE STUDY: To define the prevalence and incidence of hypothyroidism in a group of CHF outpatients in stable clinical conditions, with particular reference to the role of amiodarone therapy. RESULTS: Among the 422 enrolled patients (326 males, aged 65±12 years), 51 (12%) had a previous diagnosis of hypothyroidism while 21 (5%) were newly diagnosed at the enrolment. Then, the overall prevalence of hypothyroidism at the first evaluation was 17%and, as expected, it was significantly higher in females than males (33% vs 13%; p < 0.001). During follow-up (median 28 months) hypothyroidism occurred in further 19 patients (incidence rate: 26/1000/year) and it was mainly attributable to amiodarone therapy. Considering all together the hypothyroid patients, either those affected by thyroid failure at the enrolment than those developing hypothyroidism during the follow-up, levothyroxine therapy was continued or started in 69% of them; however, normal serum TSH values were obtained only in 76% of treated cases (mean levothyroxine dose: 69±44 mcg/day). In any case, in the group of patients affected by hypothyroidism a significantly greater occurrence of heart failure progression was observed. CONCLUSIONS: Hypothyroidism, especially the subclinical form, frequently occurs in patients affected by CHF receiving amiodarone therapy. Given the unfavorable impact of hypothyroidism on the progression and prognosis of CHF, and the opportunity to adequately manage thyroid failure by means of levothyroxine replacement therapy without the need to withdraw amiodarone, we recommend regular testing of thyroid function in CHF patients, in particular in those submitted to amiodarone therapy, in order to early diagnose a condition of hypothyroidism and titrate substitutive treatment.

Altered two-dimensional strain measures of the right ventricle in patients with Brugada syndrome and arrhythmogenic right ventricular dysplasia/cardiomyopathy.

AIMS: Brugada syndrome (BrS) is an inherited channelopathy that can be characterized by mild right ventricular (RV) abnormalities that are not detectable with conventional echocardiography. The aim of this study was to evaluate the presence of RV abnormalities in BrS patients when compared with controls and a group of patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) using two-dimensional (2D) strain analysis. METHODS AND RESULTS: We enrolled 25 BrS, 15 ARVD/C patients, and 25 controls. Right and left ventricular dimension and systo-diastolic function were evaluated by conventional echocardiography. Longitudinal systolic strain (sS) peak, systolic and early diastolic strain rate of lateral RV segments were evaluated by 2D speckle tracking analysis. Left ventricle global and segmental strain measures were also evaluated. A reduced basal or mid-RV lateral sS were the parameters mostly associated with both BrS and ARVD/C. In BrS patients the minimum sS observed in these segments was significantly lower than that of controls (-28.9±3.2% vs. -32.3±3.2%, P: 0.002) but significantly greater than that evaluated in ARVD/C patients (-24.6±6.7%, P<0.001 both vs. BrS and controls). No differences were found between the BrS and the control group when left ventricular strain measures were analysed. CONCLUSION: By 2D strain technique it is possible to observe mild abnormalities in RV systolic and diastolic function of BrS patients that are less pronounced than those observed in ARVD/C patients. These results help to better define the phenotypic characteristics of BrS patients and represent the basis for future studies aimed at testing their clinical usefulness in BrS patients.

Nitrate-potentiated head-up tilt testing in older patients: outcomes, hemodynamic responses and prodrome recognition.

BACKGROUND: To compare head-up tilt testing (HUT) outcomes and hemodynamic responses, and the prevalence and correlates of prodromes, in elderly and younger patients with suspected vasovagal syncope (VVS). METHODS: Consecutive outpatients with a history of recurrent unexplained syncope underwent HUT by being tilted to 70°; the test was potentiated by the administration of 300 µg of nitroglycerine after 20 minutes. Occurrence of VVS and hemodynamic responses during passive and nitroglycerine phases of HUT were evaluated; symptoms preceding HUT-induced syncope were recorded, together with heart rate and arterial blood pressure values. RESULTS: Four hundred and sixty of the 743 patients were HUT positive: 156 fainted during the unmedicated phase and 304 after nitroglycerine administration. The patients aged ≥65 years (n = 102) experienced VVS more frequently during the pharmacological stage of HUT; the overall rate of positive results was similar to that observed in the patients aged 36-64 years (n = 329) and only slightly lower than that observed in those aged ≤ 35 years (n = 312). In the older patients, who experienced fewer and mainly prodrome-free spontaneous syncopal episodes, HUT increased the number of premonitory symptoms, and there were no significant age-related differences in symptom prevalence or timing or the patients' hemodynamic characteristics. CONCLUSIONS: The rate of VVS induced by nitroglycerine-potentiated HUT is similar in elderly and younger patients. In the former, nitroglycerine-potentiated HUT significantly increases the prevalence of prodromes in comparison with spontaneous episodes, which suggests that it may be useful not only for diagnosis but also for patient counseling.
