Purpose: We aimed at evaluating androgen status (serum testosterone [TT] and estimated free testosterone [eFT]) and its determinants in non-diabetic elderly men with heart failure (HF). Additionally, we investigated its associations with body composition and long-term survival. Methods: Seventy three non-diabetic men with HF and 20 healthy men aged over 55years were studied. Echocardiography, 6-min walk test, grip strength, body composition measurement by DEXA method were performed. TT, sex hormone binding globulin, NT-proBNP, and adipokines (adiponectin and leptin) were measured. All-cause mortality was evaluated at six years of follow-up. Results: Androgen status (TT, eFT) was similar in elderly men with HF compared to healthy controls (4.79±1.65 vs. 4.45±1.68ng/ml and 0.409±0.277 vs. 0.350±0.204nmol/l, respectively). In HF patients, TT was positively associated with NT-proBNP (r=0.371, p =0.001) and adiponectin levels (r=0.349, p =0.002), while inverse association was noted with fat mass (r =−0.413, p <0.001). TT and eFT were independently determined by age, total fat mass and adiponectin levels in elderly men with HF (p<0.05 for all). Androgen status was not predictor for all-cause mortality at six years of follow-up. Conclusions: In non-diabetic men with HF, androgen status is not altered and is not predictive of long-term outcome. © 2017 Informa UK Limited, trading as Taylor & Francis Group.

Aim: To elucidate the prognostic role of procalcitonin (PCT) in patients with acute decompensated heart failure (ADHF) without clinical signs of infection at admission. Materials & Methods: Serial measurements of PCT and NT-proBNP were performed in 168 patients, aged 68 ± 10 years with ADHF followed by 3-month outcome evaluation. Results: Cox regression analysis demonstrated significant predictive value of baseline PCT for all-cause death/hospitalization (area under the curve: 0.67; p = 0.013) at 90th day. The patients with persistently elevated PCT or with an increase during the first 72 h of hospitalization had the worst prognosis (p = 0.0002). Conclusion: Baseline and serial in-hospital measurements of PCT have significant prognostic properties for 3-month all-cause mortality/hospitalization in patients with ADHF without clinical signs of infection at admission. © 2015 Future Medicine Ltd.
