Alterations in the lipid profile are part of the acute phase response, this corresponds to the so-called lipemia of sepsis.
To determine if the serum level of high density lipoprotein (HDL) is related to severity and mortality.
Retrospective, descriptive, cross-sectional study of patients diagnosed with abdominal sepsis. During the period from April 2016 to February 2017. The severity was determined by APACHE II, SOFA, Mannheim, CONUT, the presence of organic faults and mortality.
We included 154 cases, 59 female and 95 male; The main organ causing abdominal sepsis was the appendix 41.6%. The overall mortality was 14.3%. The presence of organic faults was 35.1%. The mean HDL level was 37.64 mg/dl (SD ± 16.16). The findings, subjected to statistical verification by Student’s t-test, showed significance among the cases with SOFA > 4 (p = 0.01) and Mannheim > 26 (p = 0.001), CONUT > 6 (p = 0.001), presence of organic failures (p = 0.001), and mortality (p = 0.003).
HDL levels are related to severity, with the development of organic failures and mortality in sepsis.
