We assessed the impact of sacubitril/valsartan on the concentrations of HF biomarkers in relation to parameters of CR using imaging techniques in patients with HFrEF. In a prospective single-center open-label study, 68 patients with symptomatic HFrEF were treated with sacubitril/valsartan and followed-up every three months for 12 months. Soluble suppression of tumorigenicity 2 (sST2), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitivity cardiac troponin I (hs-cTnI) were measured in blood samples. Additionally, echocardiography and cardiac magnetic resonance imaging (cMRI) were performed to assess heart structural and functional changes. Following treatment initiation, follow-up visits revealed an improved NYHA functional class in these patients, alongside significant decreases in all circulating biomarkers, increases in left ventricular ejection fraction (LVEF), and reductions in volume- and diameter-related LV parameters. Sustained gradual decreases in sST2 concentrations over time correlated with NT-proBNP concentrations (rho=+0.26, <em>P</em> < 0.001). Both biomarkers were inversely correlated with LVEF, and positively correlated with volume- and diameter-related LV parameters from echocardiography and cMRI. However, NT-proBNP concentrations exhibited stronger correlations with these LV parameters and were associated with the number of LV segments showing fibrosis, unlike sST2. Sacubitril/valsartan treatment in HFrEF leads to reduced sST2 and NT-proBNP concentrations with distinct decreasing curves, which are linked to reverse CR through LV-related parameters. In contrast to sST2, NT-proBNP is also associated with fibrosis, suggesting that both biomarkers unveil distinct mechanisms during CR in patients treated with sacubitril/valsartan.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"183 ","pages":"Article 117874"},"PeriodicalIF":6.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143076696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lifestyle modifications are crucial in the treatment of NAFLD; however, patient adherence remains challenging. As there is no specific treatment, drug repositioning is being researched as an alternative strategy. Statins, which are known for their cholesterol-lowering effects, are considered potential interventions for NAFLD. This review aimed to present the current understanding of the effects of statins on liver physiology in the context of NAFLD. The pathophysiology of NAFLD includes steatosis, inflammation, and fibrosis, which are exacerbated by dyslipidemia and insulin resistance. Statins, which inhibit 3-hydroxy-3-methylglutaryl-CoA reductase, have pleiotropic effects beyond cholesterol-lowering and affect pathways related to inflammation, fibrogenesis, oxidative stress, and microcirculation. Although clinical guidelines support the use of statins for dyslipidemia in patients with NAFLD, more studies are needed to demonstrate their efficacy in liver disease.

The CGM+ group received supplementation throughout the 21 days, while the other groups received a vehicle. Neurological severity score (NSS) was assessed 24 h after the last injury, and behavioral tests were completed within 14 days post-injury. Samples for the biochemical analysis were collected after euthanasia. CGM+ supplementation significantly decreased the sensory-motor deficits associated with rmTBI. Following TBI, the CGM+ group demonstrated enhanced memory and low-stress levels. Furthermore, CGM+ has been shown to modulate neurotransmitter levels and promote neurogenesis. The biochemical and molecular analysis revealed that CGM+ promotes recovery following rmTBI by modulating mitochondrial bioenergetics and BDNF pathways. The findings indicate that CGM+ can be used to manage cognitive and sensory-motor defects caused by rmTBI, such as in the case of sports injuries.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"183 ","pages":"Article 117818"},"PeriodicalIF":6.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143018064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
