Role of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio as potential biomarkers in Behçet's disease: ameta-analysis.

Abstract

The mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) have attracted interest as possible indicators of inflammation and disease activity in various diseases. This meta-analysis assessed the association between NLR, MPV, PLR, and Behçet's disease (BD) and their correlation with disease activity and thrombosis. Athorough search of the Medline, Embase, and Cochrane databases was performed to identify relevant studies. Studies comparing NLR, MPV, and PLR between patients with BD and healthy controls, as well as studies examining these measures in connection with disease activity and thrombosis in BD satisfied the inclusion criteria. The standardized mean difference (SMD) and 95% confidence interval (CI) were used to calculate the effect sizes. This meta-analysis included 24articles. The findings revealed no discernible differences in MPV between the BD and control groups (p = 0.992). NLR was substantially higher in the BD group than in the control group (p < 0.001). PLR was higher in the BD group than in the control group (p = 0.030), indicating that BD is associated with alarger PLR. Patients with active and inactive BD did not vary significantly in terms of disease activity according to the MPV. Comparing MPV between patients with BD with and without thrombosis showed no discernible changes. However, individuals with active BD had aconsiderably higher NLR and PLR than those with inactive BD (p = 0.003 and p = 0.005, respectively). The statistical significance threshold for the association between NLR, PLR, and thrombosis in patients with BD was not met. NLR and PLR can be regarded as general markers of inflammation according to the results of this meta-analysis.
