Abstract

To the Editor,

We agree with Dr Kawada that further prospective studies are required to confirm, or refute, the presence of a dose-effect relationship between specific platelet indices and the severity of chronic obstructive pulmonary disease (COPD). In our systematic review and meta-analysis, one such index, the platelet to lymphocyte ratio (PLR) was significantly associated with both the presence of COPD and its exacerbations, suggesting a dose-effect relationship with the disease. By and large, specific biomarkers for routine use in clinical practice should be easily measurable at a population level, should exhibit a predictable association with the presence and/or the severity of disease, and should potentially be modifiable by means of pharmacological and/or non-pharmacological interventions.
