Background: The current study tried to assess the effects of CKD on the severity and outcome of COPD in a population of patients who referred to our tertiary center in Tehran through a 3-year time section.
Materials and Methods: Through a retrospective cross-sectional design, the current study tried to assess the effects of chronic kidney disease (CKD) on the health situation and some spirometric and para-clinical parameters as well as their outcomes in patients who had been hospitalized for COPD. The participants had already COPD and we separate them into two groups with or without CKD.
Results: Regarding the outcome of hospitalizations, 94% of the COPD and 77.9% of the COPD+CKD group were discharged in good health condition while 6% and 22.1% deceased, respectively. This shows significantly higher death rate in the latter group and the findings obtained the odds ratio of 4.5 for CKD to raise this rate.
Conclusion: The current study could suggest an absolute relationship between CKD and COPD in terms of respiratory and blood parameters as well as the mutual effects of the diseases on the outcome of each.
