Relationship of Mean Platelet Volume (MPV) and Mean Corpuscular Volume (MCV) with the Outcome of Patients with Acute Exacerbation of COPD.

ABSTRACT

Background: Mean platelet volume (MPV) reflects the platelet production rate and stimulation, while mean corpuscular volume (MCV) represents the average size of red blood cells. Considering the possibility of the relationship between red cell index changes and different severities of chronic obstructive pulmonary disease (COPD) as well as the uncertainty of the available results in this regard, the present study aimed at evaluating the relationship between MPV and MCV in the outcome of patients with acute exacerbation of COPD (AECOPD). Materials and Methods: In this cross-sectional analytical study, 150 patients with AECOPD that referred to the emergency department (ED) were included in the study. The severity of the disease was recorded using the GOLD classification, and the MPV and the MCV were evaluated based on the reference range of kits in the laboratory. Then, the data were analyzed using SPSS software. Results: The mean MPV and MCV were 9.7±8.3 and 85.9±11.5, respectively, and had no significant difference in different severities of COPD(P>0.05). Moreover, although MCV in survivals with a mean of 88.81±6.47 was higher than that of non-survivals with a mean of 85.77±11.73, and MPV in the non-survivals with a mean of 8.53±9.74 was higher than that of survivals with the mean of 8.86±0.92, this difference was not statistically significant (P>0.05). Conclusion: Overall, the results of this study showed that the mean MPV and MCV did not have any significant relationship with AECOPD and patient outcome.
