BackgroundIn the elderly, chronic low-grade inflammation (inflammaging) is a risk factor for the development of aging-related diseases and frailty. Using data from several thousand Eastern Europeans aged 65 years and older, we investigated whether the serum levels of two proinflammatory factors, interleukin-6 (IL-6) and C-reactive protein (CRP), were associated with physical and cognitive performance, and could predict mortality in successfully aging elderly.ResultsIL-6 and CRP levels systematically increased in an age-dependent manner in the entire study group (IL-6: n = 3496 individuals, p < 0.001 and CRP: n = 3632, p = 0.003), and in the subgroup of successfully aging individuals who had never been diagnosed with cardiovascular disease, myocardial infarction, stroke, type 2 diabetes, or cancer, and had a Mini Mental State Examination (MMSE) score ≥24 and a Katz Activities of Daily Living (ADL) score ≥5 (IL-6: n = 1258, p < 0.001 and CRP: n = 1312, p < 0.001). In the subgroup of individuals suffering from aging-related diseases/disability, only IL-6 increased with age (IL-6: n = 2238, p < 0.001 and CRP: n = 2320, p = 0.249). IL-6 and CRP levels were lower in successfully aging individuals than in the remaining study participants (both p < 0.001). Higher IL-6 and CRP levels were associated with poorer physical performance (lower ADL score) and poorer cognitive performance (lower MMSE score) (both p < 0.001). This association remained significant after adjusting for age, gender, BMI, lipids, estimated glomerular filtration rate, and smoking status. Longer survival was associated with lower concentrations of IL-6 and CRP not only in individuals with aging-related diseases/disability (HR = 1.063 per each pg/mL, 95 % CI: 1.052-1.074, p < 0.001 and HR = 1.020 per each mg/L, 95 % CI: 1.015-1.025, p < 0.001, respectively) but also in the successfully aging subgroup (HR = 1.163 per each pg/mL, 95 % CI: 1.128-1.199, p < 0.001 and HR = 1.074 per each mg/L, 95 % CI: 1.047-1.100, p < 0.001, respectively). These associations remained significant after adjusting for age, gender, BMI, lipids and smoking status. The Kaplan-Meier survival curves showed similar results (all p < 0.001).ConclusionsBoth IL-6 and CRP levels were good predictors of physical and cognitive performance and the risk of mortality in both the entire elderly population and in successfully aging individuals.
A b s t r a c tBackground: Cardiovascular diseases (CVDs) are the main cause of morbidity and mortality in developed countries. Despite the progress in diagnostics and treatment, it is expected that CVD will still be the main cause of death worldwide until at least 2030. From 1991 CVD mortality in Poland systematically decreased, but it is still higher than the average in Western Europe. In 2013 CVDs were the cause of 46% of all deaths in Poland (40.9% in men and 51.1% in women) and 26.9% of deaths among persons under 65 years of age. The epidemiologic assessment of prevalence, control and treatment of CVD risk factors, and monitoring of healthy behaviour and morbidity due to diseases like coronary artery disease, hypertension and diabetes is very important for health policy planning. The WOBASZ II is the newest Polish population based survey, performed in 2013-2014 to evaluate prevalence, control, treatment, and morbidity. The study was the continuation of WOBASZ (2003WOBASZ ( -2005. Aim:To describe the goals and methods of the WOBASZ II study and to present the results of the recruitment. Methods:The WOBASZ II study was planned as a cross-sectional survey of a random sample of Polish residents aged over 20 years. The selection, using the National Identity Card Registry of the Ministry of Internal Affairs, was made as a three-stage sampling, stratified according to administrative units (voivodeships), type of urbanisation (commune), and gender. The study protocol consisted of a questionnaire used in face-to-face interviews, physical examination, and blood samples. WOBASZ II was coordinated by the Department of Epidemiology, Cardiovascular Diseases Prevention and Health Promotion of the Institute of Cardiology in Warsaw in cooperation with medical universities in Gdansk, Katowice, Krakow, Lodz, and Poznan.Results: Out of 15,120 persons, 1557 persons were not eligible. Out of eligible persons, 6170 (2760 men and 3410 women) were examined (the response rate 45.5%). The highest response rates were observed in Warminsko-Mazurskie (64.2%), Zachodniopomorskie (58.1%), and Kujawsko-Pomorskie (53.1%). Conclusions:The importance of the WOBASZ study for the monitoring of the health state of Polish society, and for the assessment of prophylaxis efficiency and treatment of CVD and metabolic diseases, as well as for the evaluation of the actions in the field of health promotion, is difficult to overstate. 682INTRODUCTION Cardiovascular diseases (CVD) due to arteriosclerosis, such as coronary heart disease (CHD) and stroke, are the main causes of morbidity, invalidity, and premature mortality in developed countries. It is estimated that despite the significant progress in diagnostics and treatment, in the majority of countries CVD will remain the main cause of mortality until at least 2030.Since 1991 mortality caused by CVD in Poland has been decreasing, but it still remains one of the highest in Europe [1]. In 2010 CVDs were the cause of 46.0% of all mortalities in Poland (40.8% in men and 51.8% in women) and the leading ca...
IntroductionHypertension is one of the main risk factors of cardiovascular diseases. The first aim of the study was to evaluate the prevalence, awareness and treatment of hypertension as well as treatment effectiveness (blood pressure < 140/90 mm Hg) in a representative sample of the Polish population over the age of 19, examined in the WOBASZ II program. The second aim was to assess the changes in these parameters between 2003–2005 (WOBASZ study) and 2013–2014 in adults aged 20–74.Material and methodsSampling was performed in three stages, stratified according to voivodeship (province), type of commune, and gender. Finally, the study included 6163 persons (3406 women and 2757 men) examined in the years 2013–2014 (aged ≥ 19 years). For comparison the data from 14 755 persons (7783 women and 6452 men aged 20–74 years) examined in the years 2003–2005 were used.ResultsIn the years 2013–2014, the age-standardized prevalence of hypertension, awareness, treatment and control was 42.7%, 59.3%, 46.1%, and 23% respectively. In the last decade an increase in the prevalence of hypertension (relative ratio (RR) 1.12; 95% confidence interval (CI): 1.07–1.18), treatment (RR = 1.26; 95% CI: 1.17–1.36) and control (RR = 2.16; 95% CI: 1.9-12.45) was found. In contrast, the awareness decreased nonsignificantly (RR = 0.98; 95% CI: 0.92–1.05).ConclusionsThe prevalence of hypertension in Poland is high, and increased by about 12% in 10 years. Although the number of treated patients and blood pressure control improved nearly twofold over the last decade, this is still below expectations. Efforts to improve the diagnosis and effective treatment of hypertension in Poland should still be intensified.
Aims Ischaemic heart failure (IHF) patients have a poor prognosis even with current guideline‐derived therapy. Intramyocardial injections of autologous or allogeneic mesenchymal stromal cells might improve cardiac function leading to better clinical outcome. Methods The SCIENCE (Stem Cell therapy in IschEmic Non‐treatable Cardiac diseasE) consortium has initiated a Horizon 2020 funded multicentre phase II study in six European countries. It is a double‐blind, placebo‐controlled trial testing the safety and efficacy of allogeneic Cardiology Stem Cell Centre Adipose‐derived Stromal Cells (CSCC_ASC) from healthy donors or placebo in 138 symptomatic IHF patients. Main inclusion criteria are New York Heart Association class II–III, left ventricular ejection fraction < 45% and N‐terminal pro‐B‐type natriuretic peptide levels > 300 pg/mL. Patients are randomized in a 2:1 pattern to receive intramyocardial injections of either CSCC_ASC or placebo. CSCC_ASC and placebo treatments are prepared centralized at Rigshospitalet in 5 mL vials as an off‐the‐shelf product. Vials are distributed to all clinical partners and stored in nitrogen vapour tanks ready to be used directly after thawing. A total of 100 × 106 CSCC_ASC or placebo are injected directly into viable myocardium in the infarct border zone using the NOGA XP system (BDS, Cordis, Johnson & Johnson, USA). Primary endpoint is a centralized core‐laboratory assessed change in left ventricular end‐systolic volume at 6‐month follow‐up measured by echocardiography. The trial started in January 2017, 58 patients were included and treated until July 2018. Conclusion The SCIENCE trial will provide clinical data on efficacy and safety of intramyocardial cell therapy of allogeneic adipose‐derived stromal cells from healthy donors in patients with IHF.
