Abnormal liver function tests in emergency departments show distinct age-based patterns. Pediatric cases link to respiratory viruses, while adults present with enteric pathogens and metabolic conditions, suggesting age-specific diagnostics.
Area of Science:
- Hepatology
- Infectious Diseases
- Emergency Medicine
Background:
- Abnormal liver function tests (LFTs) are common in emergency departments (EDs).
- Limited understanding of age-specific clinical presentations and pathogen links for abnormal LFTs.
- Need for systematic characterization of pediatric versus adult LFT abnormalities.
Purpose of the Study:
- To identify distinct clinical presentations of abnormal LFTs in pediatric and adult ED visits.
- To determine pathogen-specific associations with abnormal LFTs across different age groups.
- To analyze age-dependent patterns in abnormal LFT cases.
Main Methods:
- Retrospective cohort study of 26,874 ED visits for abnormal LFTs (2019-2023).
- Stratification of patients into pediatric (0-18 years) and adult (19-64 years) groups.
- Characterization of clinical presentations, diagnoses, pathogen correlations, and comorbidities.
Main Results:
- Pediatric visits (11.7%) showed fever-predominant profiles and links to respiratory viruses (rhinovirus, adenovirus).
- Adult visits (88.3%) revealed associations with enteric pathogens (astrovirus, sapovirus, E. coli) and gastrointestinal issues.
- Adults had clusters of metabolic comorbidities (dyslipidemia, hypertension, diabetes); adult ED visits increased during COVID-19 pandemic.
Conclusions:
- Abnormal LFTs in EDs exhibit age-dependent phenotypes and pathogen associations.
- Pediatric cases are linked to acute respiratory viral infections.
- Adult cases show novel enteric pathogen links, gastrointestinal disorders, and metabolic comorbidities, supporting age-stratified diagnostics.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
