To evaluate the outcomes of severe caffeine intoxication, including clinical manifestations and survival rates, and the impact of extracorporeal blood purification on these outcomes.
Approach:
Key Findings:
Severe caffeine intoxication can lead to life-threatening complications, primarily cardiovascular and neurologic, with 40% associated with suicidal intent and 22% with accidental exposure.
Tachycardia was present in 87% of patients, with convulsions in 18%.
Extracorporeal blood purification was linked to higher survival rates (95% vs 73%), despite higher median ingestion and serum concentrations in treated patients.
Worse outcomes correlated with greater symptom severity and higher caffeine doses.
Interpretation:
Extracorporeal blood purification, including hemodialysis, may improve survival in severe caffeine intoxication cases, but caution is advised due to the higher initial caffeine ingestion and serum concentrations in treated patients.
Limitations:
Retrospective design and reliance on case reports may limit the generalizability of the findings.
Incomplete data and potential publication bias could affect the outcomes.
No controlled comparisons available, making it difficult to draw definitive conclusions.
Conclusion:
While no definitive treatment recommendations can be made, hemodialysis may be considered for potentially lethal ingestions or severe clinical presentations, highlighting the need for further research.
A Korean cohort study found fewer kidney cancer cases among patients with type 2 diabetes who initiated sodium-glucose cotransporter 2 inhibitors vs dipeptidyl peptidase-4 inhibitors.
