R. China between December 31st, 2012 and December 28th, 2017. Concentrations of serum β 2M and other clinical indexes were measured or collected on admission, and all patients were followed up to 90 days. The relationship between β 2M and 30- and 90-day all-cause mortality was explored by Cox regression analysis adjusted for age, C-reactive protein values, N-terminal pro-brain natriuretic peptide/100, respiratory failure [RF, defined as partial arterial oxygen pressure (PaO2) < 60 mmHg on room air or PaO2 over the fraction of inspired oxygen (PaO2/FiO2) < 300], eosinopenia, consolidation, and acidaemia.Results: Median concentrations of β 2M were significantly higher in non-survivals compared to survivals within 30 days (4.11 mg/L (IQR 3.10– 6.60) vs 2.79mg/L (IQR 2.13– 3.76), P < 0.001) and 90 days (3.79 mg/L (IQR 2.61– 6.69) vs 2.79 mg/L (IQR 2.13– 3.73), P < 0.001). Serum levels of β 2M were correlated with 30-day and 90-day mortality in overall exacerbated COPD patients, with hazard ratios (HRs) of 1.09 (95% CI 1.04– 1.14, P = 0.001) and 1.09 (95% CI 1.05– 1.14, P < 0.001). In exacerbated COPD patients without RF and with RF, the HRs were 1.06 (95% CI 0.995– 1.137, P = 0.069) and 1.14 (95% CI 1.02– 1.27, P = 0.021) for 30-day mortality, 1.09 (95% CI 1.02– 1.15, P = 0.010) and 1.14 (95% CI 1.03– 1.26, P = 0.014) for 90-day mortality, respectively.Conclusion: Our data showed that concentrations of serum β 2M were associated with an increased risk of mortality, suggesting that β 2M might be a valuable predictor of poor prognosis for hospitalized patients with exacerbated COPD.Keywords: β 2-microglobulin, COPD, exacerbation, predictor, prognosis
