Do acute bacterial infections alter plasma lipid levels compared to healthy controls?
Acute bacterial infections are associated with decreased total cholesterol and HDL levels, suggesting plasma lipids could potentially serve as diagnostic indicators for these infections.
Acute infections warrant cautious lipid interpretation; cross-sectional data leaves open diagnostic utility pending prospective validation.
To assess the impact of acute bacterial infections on plasma lipid levels and to determine the value of plasma lipid measurements in the diagnosis of acute bacterial infection. Materials and methods: A cross-sectional study was conducted involving 112 patients with acute bacterial infections admitted in hospital and 112 healthy individuals as controls. Levels of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein, and triglycerides were measured in blood samples of all subjects. Mean levels of serum lipids were compared in both groups. Results: Both groups were matched based on age (P = 0.10), sex (P = 0.789), BMI (P = 0.515), and history of diabetes mellitus (P = 0.231). Compared with control subjects, in patients with acute bacterial infections, significantly lower levels of total cholesterol (P = 0.013) and high-density lipoprotein cholesterol (P = 0.001) were found. There was no statistically significant differences in triglycerides (P = 0.194) and low-density lipoprotein (P = 0.075) serum levels between patients and controls. Conclusion: These results suggested that acute bacterial infections are associated with decreased serum cholesterol and high-density lipoprotein level. Therefore plasma lipids levels may serve as indicators of acute bacterial infections.
