Type 2 Diabetes Mellitus Clinical Trial

Official title: The Early Predictors,Neutrophil-lymphocyte Ratio (NLR), Platelet-lymphocyte Ratio (PLR) and Lymphocyte-monocyte Ratio (LMR) for Developing Type 2 Diabetes Mellitus in Stable Patients With Chronic Obstructive Pulmonary Disease

Status Completed

Clinical Trial Summary

Chronic obstructive pulmonary disease(COPD), characterized by persistent airflow limitation, associated with an progressive chronic inflammatory response of the lung to noxious particles or gases, can lead to dyspnea and limited mobility and influence the life quality of patients severely. Type 2 diabetes mellitus(T2DM), as a common complication of COPD, has got more attention in comprehensive control of COPD. Stress response and metabolic disorder are more likely to happen in COPD patients with T2DM in high level inflammation status, which decrease the drug efficacy, increase the risk of acute exacerbation of COPD, complications and mortality.

Both COPD and T2DM are chronic inflammatory disease with long term, there is close relationship in occurrence and development of each other, and the patients with severe COPD are more likely to develop T2DM. Monitoring the acute inflammation maker of C reactive protein (CRP) and IL-6(interleukin-6) is the most useable way to predict the inflammatory status and condition of COPD patient with T2DM, however the chronic inflammation maker is lacking. Neutrophil-to-Lymphocyte ratio(NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) , the new, cheap and easy-tested chronic inflammatory markers, have got great research in early predicting the tumor such as nasopharyngeal carcinoma, soft tissue sarcoma and small-cell lung cancer,among them, NLR has manifest promising application in predicting insulin-resistance. However the value about NLR,PLR and LMR to predict the T2DM in COPD patients remain unknown and many articles related to NLR and COPD are retrospective.

The investigators attempt to analyze the risk factors and predict value of NLR,PLR and LMR about developing T2DM in COPD patients with prospective method.

Clinical Trial Description

All the subjects will experience the follow-up every six months, accompanying the monitoring of fast blood glucose (FBG). The complete follow-up will span three years. The follow-up for one patient will stop early when its FBG≥7.0mmol/L which indicates the patient has developed new T2DM.

The subjects will be divided into two groups according to whether patients develop T2DM at the end of each follow-up, namely, COPD patients with T2DM and COPD patients without T2DM ;
