Effects of Ecklonia cava polyphenol in individuals with hypercholesterolemia: a pilot study.

We evaluated the efficacy and safety of Ecklonia cava polyphenol (Seapolynol™, a polyphenol antioxidant and anti-inflammatory agent purified from E. cava) during a 12-week treatment period (400 mg orally once daily) in individuals with hypercholesterolemia and performed subgroup analysis for metabolic syndrome (MetS). As a noncomparative study, forty-six individuals (M:F=22:24, mean age=54±11 years) with fasting total cholesterol concentration >240 mg/dL or low-density lipoprotein cholesterol (LDL-C) concentration >130 mg/dL were enrolled. Hip circumference (100±7 cm vs. 98±7 cm, P<.01), total cholesterol (244±25 mg/dL vs. 225±37 mg/dL, P<.01), LDL-C (161±24 mg/dL vs. 146±34 mg/dL, P<.01), and C-reactive protein (2.51±3.55 mg/L vs. 1.37±1.32 mg/L, P<.05) were significantly decreased without significant adverse effect. A differential assessment according to the presence [MetS(+) group, n=18] and absence [MetS(-) group, n=28] of MetS showed that Hb(A1c) decreased significantly following 12-week Seapolynol treatment in the MetS(+) compared with the MetS(-) group (-0.3%±0.5% vs. 0.1%±0.3%, P<.01). In conclusion, although our results showed that Seapolynol treatment is effective and safe without significant adverse events or abnormal laboratory findings during a 12-week period in individuals with hypercholesterolemia, more research in a larger population with a longer-term follow-up period in a randomized placebo-controlled study is needed to confirm the results.

Pentraxin 3 as a novel marker predicting congestive heart failure in subjects with acute coronary syndrome.

BACKGROUND AND OBJECTIVES: Pentraxin 3 (PTX3) was shown to be elevated in the acute phase of acute myocardial infarction (AMI) and to have prognostic significance in AMI patients. The aim of this study was to estimate whether the value of PTX3 could be used as a prognostic biomarker, with the global registry of acute coronary events (GRACE) risk assessment tool, in patients with acute coronary syndrome (ACS). SUBJECTS AND METHODS: Between July 2007 and June 2008, 137 patient subjects (mean age : 61±12 years, M : F=108 : 29) with ACS who underwent coronary intervention, but did not have a prior percutaneous coronary intervention (PCI) and/or follow-up coronary angiogram, were enrolled. We estimated the all-cause mortality or death/MI, in-hospital and to 6 months, using the GRACE risk scores and compared these estimates with serum PTX3 concentrations. RESULTS: The serum PTX3 concentration showed a significant increase in ST segment elevation myocardial infarction (STEMI) greater than the unstable angina pectoris (UAP) group (2.4±2.1 ng/mL vs. 1.3±0.9 ng/mL, p= 0.017, respectively), but did not show a significant difference between non-ST segment elevation myocardial infarction (NSTEMI) and the UAP group (1.9±1.4 ng/mL vs. 1.3±0.9 ng/mL, p=0.083, respectively). The serum PTX3 concentration was closely related to death/MI in-hospital (r=0.242, p=0.015) and death/MI to 6 months (r=0.224, p=0.023), respectively. The serum PTX3 concentration was not related to all-cause mortality in-hospital (r=0.112, p=0.269) and to 6 months (r=0.132, p=0.191), respectively. Among the parameters determining the GRACE risk scores, the degree of Killip class in congestive heart failure (CHF) was independently associated with the supramedian PTX3 concentration [odds ratio: 2.229 (95% confidence interval: 1.038-4.787), p=0.040]. CONCLUSION: The serum PTX3 level provides important information for the risk stratification of CHF among the parameters determining the GRACE risk scores in subjects with ACS.
