Objective: To assess serum levels of carbohydrate antigen 125 (CA125) in patients with chronic congestive heart failure (CHF) and to assess any correlation with clinical symptoms and echocardiographic indices. Patients and methods: We enrolled 77 male patients (mean age: 73F10 years) admitted to the Cardiology Emergency Department (ED) with cardiac symptoms requiring hospitalization. Diagnosis of CHF was based upon medical history or initial echocardiographic evaluation on current admission. Serum CA125 was measured by an enzyme immunoradiometric assay, on admission and before discharge. Results: The median overall CA125 value was 22.4 (11.5-48.9) U/ml. Serum CA125 levels were related to the severity of CHF [New York Heart Association (NYHA) class I: 19.2 (7.2-31) U/ml, NYHA class II: 17.6 (10-23) U/ml, NYHA class III: 32 (25-77) U/ml and NYHA class IV: 34.3 (18.6-77) U/ml ( pb0.04)]. Patients in NYHA classes III and IV had significantly higher mean values of CA125, than patients in class II ( pb0.005 and pb0.05, respectively). Moreover, patients with fluid congestion (pulmonary congestion, ankle edema) had higher levels of serum CA125 than patients without congestion ( p=0.002 and pb0.03, respectively). Finally, levels of serum CA125 correlated weakly with right ventricular systolic pressure (RVSP) and renal function, while no significant correlation was found between CA125 and E wave deceleration time on Doppler echocardiography, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), liver function and the medical treatment prescribed. Conclusion: Serum CA125 is associated with the clinical severity of CHF and the symptoms and signs of fluid congestion and therefore may be a useful additional tool for the evaluation and clinical staging of these patients.
The ability to control body weight loss independent of energy intake or diet composition is reflected in the SAT transcriptome. Although cell proliferation may be detrimental, a greater mitochondrial energy gene expression is suggested as being beneficial for weight control. This trial was registered at clinicaltrials.gov as NCT00390637.
Background: Weight loss has been shown to reduce risk factors associated with cardiovascular disease and diabetes; however, successful maintenance of weight loss continues to pose a challenge. Objective: The present study was designed to assess whether changes in subcutaneous adipose tissue (scAT) gene expression during a low-calorie diet (LCD) could be used to differentiate and predict subjects who experience successful short-term weight maintenance from subjects who experience weight regain. Design: Forty white women followed a dietary protocol consisting of an 8-wk LCD phase followed by a 6-mo weight-maintenance phase. Participants were classified as weight maintainers (WMs; 0-10% weight regain) and weight regainers (WRs; 50-100% weight regain) by considering changes in body weight during the 2 phases. Anthropometric measurements, bioclinical variables, and scAT gene expression were studied in all individuals before and after the LCD. Energy intake was estimated by using 3-d dietary records. Results: No differences in body weight and fasting insulin were observed between WMs and WRs at baseline or after the LCD period. The LCD resulted in significant decreases in body weight and in several plasma variables in both groups. WMs experienced a significant reduction in insulin secretion in response to an oralglucose-tolerance test after the LCD; in contrast, no changes in insulin secretion were observed in WRs after the LCD. An ANOVA of scAT gene expression showed that genes regulating fatty acid metabolism, citric acid cycle, oxidative phosphorylation, and apoptosis were regulated differently by the LCD in WM and WR subjects. Conclusion: This study suggests that LCD-induced changes in insulin secretion and scAT gene expression may have the potential to predict successful short-term weight maintenance. This trial was registered at clinicaltrials.gov as NCT00390637.Am J Clin Nutr 2011;94:1399-409.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
