Outcome Measures

Primary Outcomes (1)

  • Define the cut off values of the nCD64 and NLR in patients with AE-COPD and stable COPD

    level of nCD64 and NLR that define exacerbation

    3 months

Secondary Outcomes (1)

  • Can nCD64 and NLR as markers be used as predictors for short term hospital outcome

    3 months

Study Arms (2)

COPD patients

A diagnosis of COPD was made by a clinical history, examination and spirometer (forced expiratory volume in 1st second/forced vital capacity (FEV1/FVC)ratio of \<0.7). The severity of COPD was graded according to the Global Initiative for Chronic Obstructive Lung Disease guidelines. \[9\] (Stage I, mild COPD: FEV1≥80.0% predicted; Stage II, moderate COPD: FEV1 80-50.0%; Stage III, severe COPD: FEV1 50- 30.0%; Stage IV, very severe COPD: FEV1\< 30.0%). The exacerbation of COPD was defined as the patient being diagnosed with COPD with two or more of the following three symptoms of exacerbations: new or worsening cough, worsened dyspnea, and worsened sputum volume and/or change in its color.

Study Population

The exacerbation of COPD is defined as the patient being diagnosed with COPD with two or more of the following three symptoms of exacerbations: new or worsening cough, worsened dyspnea, and worsened sputum volume and/or change in its color.

You may qualify if:

  • patients diagnosed as AECOPD and stable COPD ( random selection by 1:1 cross over). A diagnosis of COPD was made by a clinical history, examination and spirometer (forced expiratory volume in 1st second/forced vital capacity (FEV1/FVC)ratio of \<0.7). The severity of COPD was graded according to the Global Initiative for Chronic Obstructive Lung Disease guidelines.

You may not qualify if:

  • history of current respiratory disorders other than COPD, malignancy, systemic auto-immune disorders, recent surgery and severe endocrine, hepatic or renal diseases. Patients with pneumonia, cardiovascular and metabolic diseases
