BACKGROUND: The inappropriate use of Traditional Chinese Medicine (TCM) poses significant health risks. Realgar (As4S4), an arsenic-containing mineral traditionally consumed during China's Dragon Boat Festival, may induce acute toxicity following ingestion.
MATERIALS AND METHODS: This case series describes 8 patients (age: 1 - 80 years), including 2 children, with clinically confirmed acute arsenic poisoning subsequent to Dragon Boat Festival ingestion of realgar-containing water. We systematically evaluated clinical manifestations, laboratory parameters, and environmental arsenic concentrations. Urinary arsenic quantification was performed in all cases, with intravenous 2,3-dimercaptopropane sulfonic acid (DMPS) sodium salt initiated as chelation therapy.
RESULTS: All patients developed gastrointestinal manifestations (nausea, vomiting, and diarrhea) within 5 - 14 days post exposure, accompanied by biochemical evidence of hepatic dysfunction. Laboratory analyses confirmed elevated urinary arsenic concentrations (> 0.032 mg/L) and identified arsenic contamination in drinking water (> 0.01 mg/L), with both measures exceeding established safety thresholds. Multi-organ dysfunction syndrome (MODS) was observed in 3 patients. All cases demonstrated a favorable clinical response to intravenous DMPS sodium salt chelation therapy, achieving clinical improvements and subsequent discharge.
CONCLUSION: This case series documented acute arsenic toxicity secondary to realgar consumption in both adults and children. The findings underscore the critical need for targeted public health education initiatives and enhanced regulatory oversight regarding traditional medicinal practices, particularly during cultural festivals. Furthermore, they emphasize the necessity for heightened clinical vigilance in the prompt diagnosis and management of arsenic poisoning associated with traditional cultural practices.
