Linezolid-Associated Lactic Acidosis Triggering a Sepsis Alert: A Case Report.

Area of Science:

• Medical research
• Pharmacology
• Clinical diagnostics

Background:

• Elevated lactate levels are a common biomarker for sepsis.
• Automated sepsis alerts rely on various clinical parameters, including lactate.
• Medication side effects can alter laboratory values, potentially confounding diagnostic interpretations.

Purpose of the Study:

• To investigate a case where linezolid-induced lactic acidosis mimicked sepsis.
• To highlight the importance of considering medication-induced causes for elevated lactate.
• To emphasize the need for clinical context in interpreting automated sepsis alerts.

Main Methods:

• Case report analysis.
• Review of patient's medication history and laboratory results.
• Correlation of clinical presentation with drug-induced metabolic changes.

Main Results:

• Linezolid administration was associated with a significant increase in lactate levels.
• The elevated lactate mimicked sepsis, triggering automated alerts.
• Discontinuation of linezolid led to the resolution of lactic acidosis.

Conclusions:

• Lactate elevation alone may not be sufficient for sepsis diagnosis.
• Clinicians must consider drug-induced lactic acidosis as a differential diagnosis for elevated lactate.
• Integrating clinical context with automated alerts is crucial to prevent false sepsis diagnoses and unnecessary treatments.
