CHANGES IN INSULIN LIKE GROWTH FACTOR 1, BONE MINERAL DENSITY AND MUSCLE MASS IN ELDERLY PATIENTS WITH COPD

Backgroud: COPD is a highly prevalent systemic disease in the elderly population and it is considered as a major health problem in Egypt, However information on its prevalence, morbidity, and mortality is still lacking.COPD has a variety of extra - pulmonary manifestations and our study was conducted to determine the changes in insulin like growth factor - 1, Bone mineral density and muscle mass in elderly people with COPD. Material and Methods: case control study conducted on 90 elderly participants and they were classified into two groups: Cases Group: Forty five patients diagnosed to have COPD either mild or moderate. Control Group: Forty five healthy subjects, age and gender matched to cases recruited from the community Both groups were subjected to detailed history taking and clinical examination, comprehensive geriatric assessment, spirometry , measurement of serum IGF - 1, DXA scan to determine BMD and muscle mass. Results: The study showed that elderly COPD patients had a lower level of IGF - 1 (106.1) compared with control group (184.6) which is lower by 42%and a lower BMD in the cases group (1.15) compared to the control group (1.52) and also a lower muscle mass (47465) when compared to nor mal elderly(49400). Conclusion: the study concluded that COPD patients had a lower mean level of IGF - 1,BMD and Muscle mass than normal elderly
