Objectives: The aim of the study was to determine the prevalence of electrolyte and uric acid disturbances and their effects on mortality in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Materials and methods: This study included all consecutive AECOPD patients who were managed at our Chest Diseases department between May 2017 and December 2017. Medical records of all the subjects were reviewed, and data were collected retrospectively. Eighty-one patients with AECOPD and 103 subjects in the control group were enrolled retrospectively. The association between the COPD and control groups and biochemical parameters in patients with and without long-term oxygen therapy and noninvasive mechanical ventilation treatment in COPD patients were compared with mortality. Results: Serum magnesium, phosphorus, potassium, sodium, and calcium (Ca levels were higher in control subjects than in COPD patients (p=0.006, p=0.015, and p<0.001, respectively). While serum levels of Ca and K were significantly lower and serum level of uric acid was higher in deceased COPD patients than in alive AECOPD patients (p=0.023, p=0.001, and p=0.033, respectively), serum levels of Mg, P, and other biochemical parameters were similar. Conclusion: Serum Ca, K, and uric acid levels during the exacerbation period were significant predictors of mortality in COPD patients. In conclusion, the levels of these parameters should be measured and corrected during AECOPD treatment to decrease mortality.
