OBJECTIVE: This study aimed to evaluate the diagnostic value of the neutrophil-to-lymphocyte ratio (NLR) in early detection of metabolic syndrome (MetS) in patients with chronic obstructive pulmonary disease (COPD).
PATIENTS AND METHODS: We retrospectively enrolled hospital records of 140 COPD patients and 50 sex and age-matched healthy controls. The diagnostic values of NLR were estimated using the sensitivity, specificity, and area under the receiver operating characteristic curve (AUC).
RESULTS: In total, 140 patients with COPD of which 63 patients had MetS and 50 healthy subjects were included in the study. We found that the NLR values of the stable COPD patients were significantly higher than those of the controls (p < 0.001). Among patients with COPD, the NLR was significantly higher in patients with than without MetS (p < 0.001). The AUC of the NLR was 0.898 in patients with MetS. The optimal NLR cut-off was 2.56 and was validated in the testing set. For evaluation of MetS, the sensitivity and specificity were 84.1% and 84.4% in patients with COPD under the suggested cut-offs.
CONCLUSIONS: The NLR is a simple, effective, and practical predictor of MetS in patients with stable COPD. It has potential value in public health practice for management of patients with COPD.Free PDF Download
