Abstract:
Objective To investigate the clinical features of patients with bronchiectasis of different types.Methods One hundred and twenty two patients with bronchiectasis at stable stage were recruited from January 2014 to July 2015.The patients were typed as cystic bronchiectasis (n =45) or non-cystic bronchiectasis (n =77) by high resolution CT (HRCT),expectoration bronchiectasis (n =80) or dry brochiectasis (n =42) by clinical symptoms,bacterial colonization (n =42) or non-bacterial colonization (n =80) by sputum culture.The modified British Medical Research Council (mMRC) dyspnea scale,Leicester Cough Questionnaire (LCQ),St George's Respiratory Questionnaire (SGRQ) and pulmonary function test were used to assess the clinical features,and the episodes of exacerbations and hospitalization,and mortality during 1-year follow-up were documented.Results mMRC dyspnea scale (1.90 ± 0.94 vs.2.90±1.09,t=-5.040),LCQ (16.20±4.60 vs.11.20±2.20,t=8.114),SGRQ (36.80±13.10 vs.52.06±22.10,t=-4.780),FEV1％ pred (68.45 ±26.50 vs.52.22 ±20.60,t=3.458),FVC％ pred (72.20 ±26.32 vs.63.10 ±21.42,t =2.058),FEV1/FVC (75.14 ±20.52 vs.58.12 ± 19.82,t =4.546),diffusing capacity of the lung for carbon monoxide (DLCO) (76.24 ± 28.40 vs.54.32 ± 21.20,t =4.400),episodes of exacerbations (Z =-8.272) and hospitalization during 1-year follow-up [6(14.29％) vs.29(36.25％),x2 =6.495] in patients with dry bronchiectasis were significantly better than those in patients with expectoration bronchiectasis (all P ＜ 0.05).mMRC dyspnea scale (3.20 ± 2.10vs.2.10±1.40,t=3.131),LCQ (10.12±2.63vs.16.22 ±3.22,t=11.365),SGRQ (54.80± 18.12 vs.34.06 ± 12.10,t =6.839) and FEV1％ pred (46.52 ± 22.55 vs.58.22 ± 24.62,t=-2.611),FVC％ pred (60.24± 18.22 vs.70.10±24.20,t =-2.547),FEV1/FVC (62.54± 19.02vs.73.12 ±18.42,t=-3.025),DLCO (62.24 ±22.40 vs.74.52 ±26.26,t=-2.627),episodes of exacerbations (Z =10.213) and hospitalizations during 1-year follow-up [21 (46.67 ％) vs.14 (18.18％),x2 =1 1.260] in patients with cystic bronchiectasis were significantly more severe than those in patients with non-cystic bronchiectasis (all P ＜ 0.05).mMRC dyspnea scale (2.38 ± 1.45 vs.1.92 ± 1.14,t =2.175),LCQ (12.82 ±2.12 vs.16.20 ±3.96,t =-6.140),SGRQ (54.22±21.50 vs.41.20 ± 14.60,t =3.521) and FEV1 ％ pred (54.20 ± 21.60 vs.66.45 ± 28.24,t =-2.668),FVC％ pred (63.10 ±24.32 vs.73.46 ±25.30,t =-2.177),FEV1/FVC (62.22 ±20.80 vs.72.14 ±24.36,t =-2.243),DLCO (58.52 ± 20.42 vs.69.22 ± 25.60,t =-2.344),episodes of exacerbation (Z =19.352) and hospitalization during 1-year follow-up [19 (45.24％) vs.16 (20.00％),x2 =8.575] in patients with bacterial colonization bronchiectasis were significantly more severe than those in patients with non-bacterial colonization bronchiectasis (all P ＜ 0.05).However,there was no significant difference in mortality during 1-year follow-up (all P ＞ 0.05) among patients with different types of bronchiectasis.Conclusion Patients with cystic,bacterial colonization and expectoration types of bronchiectasis seem to have more severe symptoms,more episodes of exacerbations and hospitalizations than those of non-cystic,non-bacteria colonization and dry types of bronchiectasis.
