Neutrophil-Percentage-to-Albumin Ratio and Monocyte-to-Albumin Ratio: Utility of the Combined Biomarkers in the Prediction of 30-Day Mortality in Male Diabetes Patients Over 80 Years Old with Bloodstream Infections.

Elderly patients with diabetes mellitus (DM) are highly vulnerable to bloodstream infections (BSI), which lead to a significantly high risk of mortality. Novel inflammatory markers that attach to albumin, such as Neutrophil-percentage-to-albumin ratio (NPAR), C-reactive protein-to-albumin ratio (CAR), Monocyte-to-albumin ratio (MAR), Red blood cell distribution width-to-albumin ratio (RAR), Prognostic Nutritional Index (PNI) and C-reactive protein-albumin-lymphocyte index (CALLY index), have proven to be effective in predicting infections. However, the association between these factors and BSI in diabetes patients over 80 years old still remains to be fully elucidated.
