Monocyte-to-HDL ratio (MHR) as a novel biomarker: reference ranges and associations with inflammatory diseases and disease-specific mortality
摘要
Monocyte-to-HDL Ratio (MHR) biomarker reflects monocyte-driven inflammation and HDL’s anti-inflammatory properties. MHR’s reference ranges and prognostic utility remain undefined. We establish normal MHR reference ranges and examine its association with inflammatory diseases and mortality.
MethodsUsing NHANES data (1999–2018, 2021–2023), two sets of sex-specific MHR reference ranges were generated using two healthy adult populations (monocyte count: 6,757; monocyte percentage: 6,817). Further analyses utilized MHR by monocyte count for more straightforward interpretation. Adjusted associations between MHR and inflammatory diseases were assessed in 49,929 adults, and disease-specific mortality in 35,781.
ResultsThe 2.5th–97.5th percentiles for MHR by monocyte count were 0.175 (90% CI: 0.167–0.184) to 0.709 (90% CI: 0.690–0.727) in males and 0.135 (90% CI: 0.130–0.140) to 0.511 (90% CI: 0.503–0.520) in females, with similar trends for MHR by monocyte percentage. High MHR was most strongly associated with diabetes (aOR = 1.76, p < 0.001) and cardiovascular disease (aOR = 1.69, p < 0.001), while mortality risk was highest for kidney disease (aHR = 3.13, p < 0.001) and diabetes (aHR = 2.26, p < 0.001).
ConclusionMHR is a feasible and accessible biomarker of inflammation and lipid dysregulation that can be derived from routine laboratory tests and shows strong associations with cardiometabolic diseases and disease-related mortality.
