Abstract
OBJECTIVE: Deep venous thrombosis (DVT) is associated with a state of increased inflammation at the time of diagnosis as either a cause or consequence. The neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) are easy-to-obtain, low-cost biomarkers of systemic inflammation. The objective of this study was to determine whether these two ratios at the time of diagnosis can be an indicator of thrombus burden in terms of thrombus location in DVT. METHODS: Patients with a diagnosis of DVT confirmed with venous Doppler ultrasound in a single referral center for cardiovascular diseases between 2014 and 2018 were retrospectively analyzed. Of 1852 patients, 933 with blood counts at time of diagnosis were included. The NLR and PLR were calculated from blood count results. Patients were categorized according to the level of thrombus and the number of vein segments involved as evidenced by Doppler ultrasound findings. RESULTS: Iliac, femoral, popliteal, and crural groups had a mean NLR of 5.07, 4.18, 3.59, and 3.24, respectively (P = .002), and a mean PLR of 1.82 × 107, 1.76 × 107, 1.47 × 107, and 1.64 × 107, respectively (P = .011). Patients with proximal DVT had a higher mean NLR (4.40 ± 4.28 vs 3.54 ± 3.55; P = .05) and PLR (1.77 × 107 ± 1.3 × 107 vs 1.49 × 107 ± 1.08 × 107; P = .03) than patients with distal DVT. NLR increased with the number of vein segments involved (P = .001), but this correlation did not exist with PLR (P = .097). CONCLUSIONS: A state of inflammation, demonstrated by NLR and PLR, at the time of diagnosis in DVT patients correlates with disease burden in terms of thrombus location. Further studies are required to assess the clinical value of NLR and PLR at the bedside.
