Increased Basal and Alum-Induced Interleukin-6 Levels in Geriatric Patients Are Associated with Cardiovascular Morbidity

چکیده
BACKGROUND/AIM OF THE STUDY Low-grade systemic inflammation was suggested to participate to the decline of physiological functions and increased vulnerability encountered in older patients. Geriatric syndromes encompass various features such as functional dependence, polymorbidity, depression and malnutrition. There is a strong prevalence of cardiovascular diseases and related risk factors and chronic cytomegalovirus infections in the geriatric population. As these underlying conditions were proposed to influence the inflammatory state, the aim of this study was to assess their potential contribution to the association of geriatric syndromes with inflammatory parameters. METHODOLOGY We recruited 100 subjects in the general population or hospitalized for chronic medical conditions (age, 23-96 years). We collected information on clinical status (medical history, ongoing comorbidities, treatments and geriatric scales), biological parameters (hematological tests, cytomegalovirus serology) and cytokines production (basal and alum-induced interleukin (IL)-1β and IL-6 levels). Using stepwise backward multivariate analyses, we defined which set of clinical and biological variables could be predictive for increased inflammatory markers. PRINCIPAL FINDINGS We confirmed the age-associated increase of circulating IL-6 levels. In contrast to geriatric scales, we found history of cardiovascular diseases to be strongly associated for this parameter as for high IL-6 production upon ex vivo stimulation with alum. CONCLUSIONS Association between low-grade inflammation and geriatric conditions could be linked to underlying cardiovascular diseases.

Background and purpose: Heart failure (HF) is characterized by decreased ability of the heart to provide sufficient blood flow or fill with the blood. Hyponatremia is the most commonly seen electrolyte abnormality in patients with heart failure that is associated with increased morbidity and mortality. The aim of this study was to assess the correlation between hyponatremia and high risk clinic...

Background: CD163-expressing macrophages are involved in the inflammatory response in asthma. Objective: To assess sputum and serum soluble CD163 (sCD163) and cytokine levels in patients with asthma. Further discussed was the difference between sCD163 and other classic inflammatory mediators. Methods: Sputum was successfully induced in asthma patients (n=85) and healthy controls (n=21).

[Long term effect of autoadjusting positive airway pressure on C-reactive protein and interleukin-6 in men with obstructive sleep apnoea syndrome].
BACKGROUND AND OBJECTIVES Obstructive sleep apnoea (OSA) has been increasingly linked to cardiovascular disease. Inflammatory processes associated with OSA may contribute to this morbidity. Some studies have reported serum levels of high sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) to be increased in these patients. PRIMARY OBJECTIVE investigate the impact of short and lon...
