Impact of diabetes mellitus on mortality in patients with acute exacerbation of chronic obstructive Pulmonary disease: a meta-analysis and systematic review
To measure the impact of diabetes on mortality in patients with acute exacerbation of COPD (AECOPD) and establish an evidence-based basis for clinical risk stratification and personalized intervention.
Key Findings:
A total of 9 investigations were incorporated, encompassing 23,883 subjects. Diabetes elevated the mortality risk for individuals with AECOPD in univariate analysis (HR = 1.45, 95% CI (1.19, 1.77), P < 0.0001).
No significant correlation was found in multivariate analysis (HR = 1.50, 95% CI (0.45, 5.00), P = 0.513).
Subgroup analysis indicated increased mortality risk in hospitalized AECOPD patients with diabetes, but not in those in intensive care units.
Significant relationship established in case-control studies, but not in cohort studies.
Interpretation:
The meta-analysis reveals variable relationships between diabetes and mortality in AECOPD patients, suggesting that diabetes may not be an independent risk factor for mortality, highlighting the need for further research.
Limitations:
Methodological issues and variability in study design may influence results.
Need for additional well-structured, sufficiently powered prospective cohort studies.
Conclusion:
Existing evidence does not affirm diabetes as an independent risk factor for mortality in AECOPD. Further research is necessary to clarify the prognostic effect of diabetes on AECOPD patients.
