Low-Dose Aspirin Plus Low-Dose Warfarin May be Life-Saving Treatment Regimens in Cases with Severe Chronic Obstructive Pulmonary Disease

Abstract

Background: Sickle Cell Diseases (SCDs) are inborn and catastrophic processes on vascular endothelium, particularly at the capillaries. Methods: All patients with the SCDs were included. Results: We studied 222 males and 212 females with similar mean ages (30.8 vs 30.3 years, p>0.05, respectively). Beside Chronic Obstructive Pulmonary Disease (COPD) (25.2% vs 7.0%, p<0.001), smoking (23.8% vs 6.1%, p<0.001), alcohol (4.9% vs 0.4%, p<0.001), transfused red blood cells (RBCs) in their lives (48.1 vs 28.5 units, p=0.000), disseminated teeth losses (5.4% vs 1.4%, p<0.001), ileus (7.2% vs 1.4%, p<0.001), cirrhosis (8.1% vs 1.8%, p<0.001), leg ulcers (19.8% vs 7.0%, p<0.001), digital clubbing (14.8% vs 6.6%, p<0.001), coronary heart disease (CHD) (18.0% vs 13.2%, p<0.05), chronic renal disease (CRD) (9.9% vs 6.1%, p<0.05), and stroke (12.1% vs 7.5%, p<0.05) were all higher, and autosplenectomy (50.4% vs 53.3%, p<0.05) and mean age of mortality were lower in males, significantly (30.2 vs 33.3 years, p<0.05). Conclusion: The hardened RBCs-induced capillary endothelial damage initiates at birth, and terminates with multiorgan failures even at childhood in the SCDs. Parallel to the COPD, all of the atherosclerotic risk factors or consequences including smoking, alcohol, disseminated teeth losses, ileus, cirrhosis, leg ulcers, digital clubbing, CHD, CRD, and stroke were higher, and autosplenectomy and mean age of mortality were lower in males which can not be explained by effects of smoking and alcohol alone at the younger age. So COPD may have an atherosclerotic background, and low-dose aspirin plus low-dose warfarin may be life-saving treatment regimens in severe COPD.
