Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide and results in an economic and social burden that is both substantial and increasing This study was done to measure serum uric acid levels in chronic obstructive pulmonary disease patients. Serum uric acid, the final product of purine degradation, has been shown to be increased in the hypoxic state as well as in systemic inflammation including patients with chronic obstructive pulmonary disease (COPD). elevated serum uric acid level may be a noninvasive indicator for COPD severity and hypoxemia in stable COPD patients. Therefore, it is suggested to assess serum UA as an important and additional parameter for COPD patientsddd |
