Galectin-3 and ST2 are emerging biomarkers involved in myocardial fibrosis. We evaluate the relevance of a multiparametric biomarker approach based on increased serum levels of NT-proBNP, galectin-3, and ST2 in stratifying the prognosis of chronic heart failure (CHF) outpatients. In 315 CHF outpatients in stable clinical condition clinical and echocardiographic evaluations were performed. Routine chemistry and serum levels of NT-proBNP, galectin-3, and ST2 were also assessed. During a 12 month follow-up, cardiovascular death, and/or heart failure (HF) occurred in 64 patients. The presence of NT-proBNP, galectin-3, and ST2 were higher than the recommended cutoffs and were all associated with events at univariate Cox regression analysis, as well as in a multivariate analysis including the three biomarkers. When a score based on the number of biomarkers above the recommended cut-offs was used (in a range of 0–3), it was associated with events both with respect to the univariate (HR 2.96, 95% CI 2.21–3.95, p < 0.001, C-index 0.78) and the multivariate (HR 1.52, 95% CI 1.06–2.17, p: 0.023, C-index 0.87) analyses, after correction for the variables of a reference model. Our results suggest that an easy prognostic approach based on the combination of three biomarkers, although with partially-overlapping pathophysiological mechanisms, is able to identify patients with the highest risk of heart failure progression.
Aim: The aim of the study was to evaluate the association between Gal-3 serum levels and the progression of renal dysfunction in chronic heart failure outpatients. Methods & results: This prospective study of 260 chronic heart failure patients showed that Gal-3 was associated with 1-year worsening of renal function both in univariate (odds ratio: 1.12; 95% CI: 1.06–1.18; p < 0.001) and in forward stepwise multivariate (odds ratio: 1.09; 95% CI: 1.03–1.15; p = 0.004) logistic regression analyses. Moreover, high Gal-3 levels at baseline were associated with a progressive decline in the estimated glomerular filtration rate. Conclusion: Gal-3 is a biomarker associated with the progression of renal function decline thus further supporting its possible usefulness in predicting cardiorenal syndrome progression.
Herein, we present the case of a 58 y–o Caucasian man with unremarkable cardiovascular history and a strong family history for cancer. He was diagnosed with lung adenocarcinoma IVb (pleura, pleural effusion, lymph nodes), PDL1: 2% TPS and absence of actionable driver mutations on DNA and RNA NGS (only ERBB2 mutation). Started first–line chemotherapy with cisplatin–pemetrexed regimen and immunotherapy with pembrolizumab. He developed common/superficial femoral and popliteal deep vein thrombosis (DVT) and pulmonary embolism (PE). The patient started low–molecular–weight heparin (LMWH) namely enoxaparin 1 mg/kg x 2/d (weight: 65 Kg). After 1 mo, CT showed PE resolution. Due to DVT persistence and patient’s preference for oral administration, LMWH was replaced with direct oral anticoagulant (DOAC) namely edoxaban 60 mg 1 cp/d. After 2 mo, resolution of common femoral and popliteal vein thrombosis with partial recanalization of superficial femoral DVT were detected. However, he developed brain metastases treated with WB radiotherapy. We decided for edoxaban full dose long–term anticoagulant treatment with monthly cardioncological surveillance. After 6 mo since cancer diagnosis, the patient was still adherent to DOAC therapy, although in a maintenance combined regimen pemetrexed–pembrolizumab based, without both drug–drug interactions and brain bleeding. Conclusions Thromboembolism is the second leading cause of death in malignancy. In this clinical case, a man with advanced lung cancer developed extended cancer–associated thrombosis (CAT). However, the appearance of brain metastases has posed a clinical dilemma: to continue or to withdraw the anticoagulant therapy and, also, which drug to choose between LMWH and DOAC. Literature is limited on the use of DOACs in cancer patients with brain metastases. Besides, current guidelines neither advocate contraindication to DOAC, nor suggest caution as requested for gastrointestinal and genitourinary sites of cancer. We decided to proceed with edoxaban therapy, despite chemotherapy combined to immunotherapy were still ongoing and the concurrent appearance of brain metastases, with good results in efficacy, patient’s adherence and, mostly, safety. In conclusion, in regard to our clinical experience, we point out DOAC as a reliable and manageable therapeutical choice in CAT, also in active cancer patients with brain metastases receiving chemo–immunotherapy.
