简要总结
•Examine whether COPD is associated with accelerated aging using a biological marker of aging and dermatological score
详细描述
Chronic Obstructive Pulmonary Disease (COPD) results from gene(G)-environment(E) interactions occurring over the lifetime(T) of the individual (GETomics) that can damage the lungs and/or alter their normal development/aging processes.
In COPD, processes including oxidant/antioxidant, protease/antiprotease, and proliferative/ antiproliferative balance, and the control of the inflammatory response become dysfunctional, as in aging. A close relationship between the pathogenesis of COPD and aging has been reviewed, and an increase regarding aging has been identified Aging is defined as a time-dependent progressive loss of physiological integrity, resulting in impaired function and increased vulnerability to death many chronic diseases are dependent on age and encompass physiological mechanisms related to the aging process The interconnection of the different markers of aging has not yet been studied in clinical subjects. We hypothesized that these markers, representing different interrelated aspects of the aging process, are altered in a cohort of COPD patients compared to the control group. These markers include growth hormone(GH), "Red cell distribution width (RDW) and SCINEXA (SCore for INtrinsic and EXtrinsic skin Aging) score as a read-out of biological age. SCINEXA is a validated score which measures the intrinsic and extrinsic factors regarding chronological skin aging and aging due to chronic exposure to ultraviolet (UV) radiation, Respectively.
The major feature of aging is the role of hormones as key regulators of human muscle metabolism and physical function. Growth hormone (GH) actions impact growth, metabolism, and body composition and have been associated with aging and Longevity. While, red cell distribution width (RDW), a part of the standard complete blood count (CBC), is a simple and non-invasive parameter that can be used as a biomarker in evaluating the severity and mortality rates in COPD patients in acute attacks. Also, Elevated RDW has been associated with degenerative conditions in aging.

结局指标
主要结局
Level of GH and RDW in relation to COPD patient age.
时间窗: 1 week
measuring level of GH and in COPD patients and control group
SCINEXA score in relation to COPD patient chronological age.
时间窗: 1 week
measuring SCINEXA score (Score for Intrinsic and Extrinsic skin Aging) in COPD patients and in control group and comparing it with chronological age. - 18 signs of extrinsic aging, each item will be scored as 0 (none), 1 (mild), 2 (moderate) or 3 (severe). For some items (uneven pigmentation, cutis rhomboidalis nuchae, elastosis, comedones and cysts of Favre Racouchot, and malignant skin tumors, a binary scale was used: (yes) or (no). Maximun possible score is 54
Comparing level of GH with the chronological age
时间窗: 1 week
Compare level of GH with the chronological age of patients and controls to detected premature aging
