Aim: We aimed to evaluate platelet-to-lymphocyte ratio (PLR) in patients with sarcoidosis.
Methods: A total of 310 sarcoidosis patients and 220 healthy controls retrospectively were recorded in this study.
Results: PLR was significantly higher in patients with sarcoidosis than in the control group, and was also significantly higher in patients with pulmonary involvement in stage 2-3-4 than in stage 1. PLR were significantly positive correlated with erythrocyte sedimentation rate. The cut-off values for PLR for predicting a sarcoidosis diagnosis were determined as 158.
Conclusion: Increase in PLR value can be used for guiding both the diagnosis of sarcoidosis and the involvement of parenchyma.
