Serum triglyceride elevations in patients with septicemia

Area of Science:

• Infectious Diseases
• Clinical Biochemistry

Background:

• Septicemia and endocarditis are serious infections.
• Hypertriglyceridemia can be associated with various medical conditions.

Purpose of the Study:

• To investigate the prevalence of elevated serum triglyceride levels in patients with septicemia or endocarditis.
• To determine the relationship between triglyceride levels and the type of causative microorganism.
• To observe changes in triglyceride levels during infection resolution.

Main Methods:

• Retrospective analysis of 239 patients diagnosed with septicemia or endocarditis.
• Measurement of serum triglyceride levels at diagnosis.
• Categorization of infections based on causative microorganisms (gram-negative rods vs. gram-positive cocci).

Main Results:

• 17% (41/239) of patients presented with serum triglyceride levels above 2.2 mmol/l (mean 3.1 mmol/l).
• Elevated triglycerides were significantly more common in infections caused by gram-negative rods compared to gram-positive cocci (p < 0.001).
• In 22 out of 37 patients, triglyceride levels returned to normal during the course of infection treatment.

Conclusions:

• Hypertriglyceridemia is a notable finding in a subset of patients with septicemia or endocarditis.
• Gram-negative bacterial infections are more frequently associated with elevated triglycerides in this patient population.
• Serum triglyceride levels may serve as a potential indicator that can normalize with effective infection management.
