Are Lipoprotein Levels and Ratios Able to Predict Mortality due to Sepsis?

To compare lipoprotein levels, and non-HDL to high-density lipoprotein (HDL) ratios of survivors and nonsurvivors of sepsis, and to determine the predictivity levels of specified parameters in mortality. Descriptive study. Department of Internal Medicine, Kirikkale University, School of Medicine, Training and Research Hospital, Kirikkale, Turkey, from December 2017 to December 2018. The study subjects included 37 non-survivors and 32 survivors of sepsis with similar ages, comorbidities, and disease activities. The total lipoprotein levels, and non-HDL to HDL ratios of the participants were compared retrospectively. HDL and non-HDL to HDL ratios were found to be different between the two groups. The cut-off levels of these values were determined as 32 and 3.4, respectively. The cut-off levels found in the study suggest that the low HDL levels and high non-HDL to HDL ratios significantly increase the mortality risk for patients (OR=1.8 and 3.45, respectively). Non-HDL to HDL ratio may be used as a useful tool for predicting sepsis mortality. These values may also be included as a part of scoring systems. Further investigations are needed to clarify the role of lipoproteins in sepsis.
