BACKGROUND: In combination with other traditional Chinese medicines, Breynia officinalis, a species of Euphorbiaceae, has long been used to treat contusions, heart failure, venereal diseases, growth retardation, and conjunctivitis. B. officinalis, regarded as a poison, was mistaken for a similar plant, Securinega suffruticosa, and cooked in a soup used for the treatment of muscle soreness, lumbago, and as a tonic in this outbreak. CASE SERIES: Nineteen patients, 11 males and 8 females (average age 49.2 +/- 9.1 years) consumed an average of 130 mL (30-900 mL) of soup containing B. officinalis stems. Fourteen patients developed diarrhea, 10 experienced nausea and chilly sensations, 9 had sensations of abdominal fullness, and 7 suffered from vomiting. The results of liver function tests (LFTs) indicated that the observed maximum median level of alanine aminotransferase (ALT) was 647U/L (range 89-9440 U/L), aspartate aminotransferase (AST) 314 U/L (range 47-7756 U/L), alkaline phosphatase 251 U/L (range 224-278 U/L), and gamma glutamyl transpeptidase 106 U/L (range 84-313 U/L). The median time to the observed median peak levels was 3 days for ALT, 2 days for AST, 5 days for alkaline phosphatase, and 12 days for gamma glutamyl transpeptidase. With supportive treatment, the majority of abnormalities in 14 of the cases resolved within 6 months of exposure. CONCLUSIONS: The consumption of a soup containing B. officinalis Hemsley resulted in dose-related toxic effects. Clinical toxicity consisted primarily of gastrointestinal symptoms and signs and hepatotoxicity. Hepatocellular liver injury rather than cholestatic liver injury was observed. Marked jaundice did not develop.
