The Course of Renal Functions in COPD. Two Statition: Exacerbation and Stable Period

OBJECTIVE: Comorbidities in chronic obstructive pulmonary disease (COPD) are important factors that determine the prognosis of the disease. However, there are few studies about renal dysfunction. We aimed to compare the renal functions in COPD patients with stable and exacerbation periods and to determine the frequency of acute renal failure (ARF) during exacerbation. MATERIALS AND METHODS: The files of 320 patients with COPD (forced expiratory volume in 1 s/forced vital capacity RESULTS: Ninety (80.4%) of the patients were male and 23 (19.6%) were female. In the exacerbation period, blood urea nitrogen (P CONCLUSION: In COPD exacerbation period, kidney function is affected negatively in most patients (even if it does not reach the ABY border) and tends to improve in the stable period. In patients with COPD, it is thought that the causes of respiratory failure negatively affect renal function.
