Abstract

Background: Patients with COPD often have exacerbations which frequently require hospitalization, resulting in higher mortality rates and costs than patients managed at OPD. Some easily available blood parameters in both stable COPD and AECOPD patients are measured that can be done in every patient even in poor resource settings. Finally, Results were analysed statistically to find out if there is any presence of significant difference of biochemical profile in stable COPD patients and AECOPD patients with or without any prognostic significance.

Methods: In institution based observational case control study, authors measured 1.  FBS and PPBS 2. Serum Urea and Creatinine 3. Serum Electrolytes- Na+, K+, Cl- 4. LFT  5. Uric acid in both stable COPD(n=50) and AECOPD (n=50) patients. Finally, Results were analysed statistically to find out if there is any presence of significant difference of biochemical profile in stable COPD patients and AECOPD patients.

Results: AECOPD patients had statistically significant higher urea, uric acid levels and higher fasting hyperglycemia than stable COPD patients. Hypernatremia, hyponatremia and hyperkalemia, hypokalemia - all were significantly higher in AECOPD group. Low level of serum bilirubin and higher level of AST and ALP were common in AECOPD patients. AECOPD patients with high urea value (>50 mg/dl) (but not high creatinine) was associated with poor patient outcome in respect to ICU transfer, death and prolonged hospital stay. Low bilirubin, high ALP and AST level in AECOPD patients was associated with higher ICU transfer and mortality but only high ALP level was associated with prolonged hospital stay. High uric acid level (>6 mg/dl) was a major determinant of ICU transfer, mortality and prolonged hospital stay.

Conclusions: Predicting exacerbation by these parameters early in the course of disease can decrease morbidity and mortality as well as health care cost to great extent. By measuring the changes in it can also be predicted early who will need ICU support in future and who can be treated at ward.
