Background: The effect of association between chronic obstructive pulmonary disease
(COPD) and diabetes (DM) on platelet function has not been studied before.
Objectives: To evaluate the effect of the association between COPD and DMon platelet
function and C reactive protein (CRP).
Patients and Methods: This case control study was carried out on 110 stable COPD
patients who were classified into diabetic and nondiabetic groups. In addition, 40
apparently healthy, age and sex-matched individuals were included in this study as
a control group. Chest X-ray, pulmonary function testing and arterial blood gases
were done for COPD patients. CRP and complete blood count (CBC) were measured
in both patient and control groups.
Results: Mean platelet volume (MPV), platelet distribution width (PDW), platelet
crit (PCT) and CRP were significantly higher in COPD patients either nondiabetic
or diabetic compared to control group. Moreover, MPVand CRP markers were significantly
higher in COPD diabetic patients compared to nondiabetic. There was no
significant difference in various laboratory data among different stages of COPD
either diabetic or nondiabetic (P>0.05). In COPD patients, MPV was a significantly
positively correlated with CRP and PDW(r50.346, P<0.001; r50.510, P<0.001,
respectively) and negatively correlated with PLT count (r520.294, P50.002).
Conclusion: MPV, PDW, PCT and CRP were significantly higher in COPD patients
either nondiabetic or diabetic. Platelet function may be modified by the systemic
inflammation that associated with COPD. Platelet activation as a prothrombotic
sequence of this disease may be used as novel therapeutic target.
