Changes characteristics of serum cholesterol indicators in sepsis patients and its correlation with prognosis / 中国综合临床

ABSTRACT

Objective@#To explore the relationship between the change of blood cholesterol and prognosis in patients with sepsis.@*Methods@#The clinical data of 236 patients with sepsis (observation group) admitted to Nanjing Hospital Affiliated to Nanjing Medical University from February 2014 to December 2018 were analyzed retrospectively.The general clinical data, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) of the two groups were compared with 236 patients without sepsis in the same period as the control group, high density lipoprotein cholesterol (HDL-C) and other biochemical indexes; sepsis patients were divided into survival group and death group according to the prognosis, and the related factors affecting the prognosis were analyzed by multi factor Logistic regression.@*Results@#The survival rate of sepsis patients was 60.6% (143/236), the mortality rate was 39.4% (93/236), 143 cases in survival group and 93 cases in death group.Compared with control group, the levels of serum TC ((2.51±1.20) mmo/L vs.(3.42±1.33) mmo/L, t=6.385) and HDL-C ((1.62±0.91) mmo/L vs.(2.53±0.79) mmo/L, t=5.526) in observation group were significantly lower (all P<0.05), and that of LDL-C showed no statistically significant difference((1.95±0.93) mmo/L vs.(2.11±0.84) mmo/L, t=0.958, P>0.05). In observation group, the patients in death group were older than those of the survival group ((75.4±10.3) years vs.(64.3±16.0) years, t=4.984, P<0.05), serum creatinine (SCr) was higher than that of survival group((252.3±65.2) μmol/L vs.(168.3±47.8) μmol/L, t=5.604, P<0.05), the levels of serum TC ((2.20±1.46) mmo/L vs.(2.91±1.12) mmo/L, t=6.157, P<0.05), HDL-C ((1.41±0.51) mmo/L vs.(1.95±0.65) mmo/L, t=5.090, P<0.05) and LDL-C ((1.71±0.67) mmo/L vs.(2.02±0.84) mmo/L, t=4.525, P<0.05) were significantly lower than those of survival group.Logistic regression analysis showed that age was the risk factor of death in sepsis patients (OR=1.035, 95%CI 1.012-1.049, P=0.008), and TC was the protective factor on the prognosis of sepsis patients (OR=0.748, 95%CI 0.693-0.822, P=0.015).@*Conclusion@#TC and HDL-C were significantly decreased in sepsis patients, while those who died were further decreased than those who survived.As a protective factor TC can be an effective biochemical index to evaluate the prognosis of patients with sepsis.
