Insights
Serum heart-type fatty acid-binding protein (H-FABP) is a potential biomarker for assessing carbon monoxide (CO) poisoning severity and guiding hyperbaric oxygen (HBO) therapy selection.
Area of Science:
- Biochemistry
- Toxicology
- Emergency Medicine
Background:
- Carbon monoxide (CO) poisoning is a significant public health concern.
- Accurate evaluation of CO poisoning severity is crucial for appropriate patient management.
- Novel biomarkers are needed to improve diagnostic and therapeutic strategies.
Purpose of the Study:
- To investigate the diagnostic and prognostic role of serum heart-type fatty acid-binding protein (H-FABP) in acute carbon monoxide (CO) poisoning.
- To assess the correlation between H-FABP levels and clinical severity.
- To evaluate H-FABP as a predictor for hyperbaric oxygen (HBO) therapy.
Main Methods:
- A study involving 40 acute CO poisoning patients and 15 healthy controls.
- Serum H-FABP levels were measured on admission and at 6, 12, and 18 hours post-admission.
- Patients were stratified by clinical severity (mild, moderate, severe) and treatment (HBO vs. normobaric oxygen).
Main Results:
- Serum H-FABP levels were elevated in CO poisoning patients compared to controls.
- H-FABP levels negatively correlated with Glasgow Coma Scale scores.
- Higher H-FABP levels were observed in severe cases and in patients receiving HBO therapy.
- A cutoff of 1.5 ng/mL for H-FABP indicated a need for HBO treatment with 85.7% sensitivity and 69.7% specificity.
Conclusions:
- Serum H-FABP shows promise as a biomarker for evaluating CO poisoning severity.
- H-FABP may aid in selecting patients who would benefit from HBO therapy.
- Serial H-FABP measurements reflect the dynamic changes in CO poisoning.
Background:
The aim of this study was to investigate the role of serum heart-type fatty acid-binding protein (H-FABP) in the evaluation of patients with carbon monoxide (CO) poisoning.
Methods:
Forty patients with acute CO poisoning admitted to the emergency department and 15 healthy adults as the control group were included in the study. Serum H-FABP levels of patients were studied on admission and at the 6th, 12th, and 18th hours. Patients were divided into 3 groups according to clinical severity as mild, moderate, and severe. Patients were also divided into 2 groups according to treatment with hyperbaric oxygen (HBO) or normobaric oxygen.
Results:
Serum H-FABP levels of the patients were higher than those of the control group. There was a negative correlation between H-FABP levels and Glasgow Coma Scale score on admission. Heart-type fatty acid-binding protein levels were significantly higher in patients in the severe compared with mild group. Heart-type fatty acid-binding protein levels in patients treated with HBO were significantly higher than in those treated with normobaric oxygen. The cutoff value of serum H-FABP as an indicator for HBO treatment was determined as 1.5 ng/mL or higher, with a sensitivity of 85.7% and specificity of 69.7%. Serial measurement revealed that H-FABP level peaked at the sixth hour and reduced over time but remained higher than in the control group at the 18th hour.
Conclusion:
Heart-type fatty acid-binding protein may be a promising novel biomarker in the evaluation of clinical severity and in the selection of patients for HBO therapy in acute CO poisoning.
