[Poisoning with Jatropha curcas: 24 cases reported to Paris and Marseille Poisons Centers]. / Intoxications par pignons d'Inde (Jatropha curcas): 24 observations rapportées aux centres antipoison de Paris et Marseille.

Jatropha curcas L. is an inedible plant belonging to the Euphorbiaceae family that is growing in subtropical zones of all continents. We report a series of 24 cases of poisoning with J. curcas seeds or fruits reported to poison centers in Paris and Marseille between December 2000 and June 2014. Fifteen adults and 9 children ingested J. curcas seeds or fruits. All patients experienced gastrointestinal disorders, within the first hours following ingestion: nausea, vomiting, diarrhea and abdominal pain. Laboratory investigations performed in 10 patients revealed minor abnormalities: CK elevation (8 cases), dehydration (5 cases) with moderate elevation of serum creatinine levels (3 cases), and mildly increased serum bilirubin (8 cases). Complete remission of all clinical signs was observed within 48 hours in the 20 cases for which the outcome was known. Previously published cases of J. curcas poisoning were very similar to ours: As in our series, gastrointestinal disorders were always present. They were sometimes associated with neurological or cardiovascular signs, and hepatic or renal disorders; these were generally interpreted as complications of severe gastroenteritis, although direct toxic effects could not be formally excluded. In most cases, simple supportive measures were sufficient to ensure complete recovery within 24-48 hours. J Curcas poisoning incidence is certainly increasing because the plant is cultivated to produce biodiesel and is now largely present in most subtropical countries. As a consequence, local health professionals should be informed of the toxic properties of this plant.

Toxic hepatitis induced by a herbal medicine: Tinospora crispa.

Herbal remedies are becoming increasingly popular in many countries. Tinospora species (Menispermaceae) is commonly used as a herbal medicine in South Asia, but very few toxic effects have been described. We report a case of acute hepatitis associated with chronic use of high doses of Tinospora crispa. A 49-year-old male with chronic low back pain bought a herbal medicine at a market in Vietnam that was supposed to be Tinospora crispa, and started to take 10 pellets per day. He had no medical history and did not take any other drugs or toxins. Four weeks later; he developed dark urine and pale stools, associated with asthenia and right hypochondrial pain. Two months after starting treatment, he was referred to the hepatology department with jaundice. Blood tests showed aspartate aminotransferase: 1.169 IU/l, alanine aminotransferase: 2.029 IU/l, total bilirubin: 20.47 mg/dl, direct bilirubin: 13.29 mg/dl, and γ-glutamyltransferase: 243 IU/l. Viral and autoimmune hepatitis were eliminated. Upper abdominal ultrasound was normal. Histopathological findings were consistent with a toxic reaction. The herbal medicine was stopped on admission and the patient fully recovered without treatment, with normal liver function 2 months after the acute episode. Tinospora crispa was clearly identified in the pellets by microscopic analysis of the botanical characters combined with chromatographic fingerprints. The use of herbal medicines containing Tinospora crispa can induce toxic hepatitis. Recovery can be complete after discontinuation. This case highlights the risk associated with traditional herbal remedies.

Tender Nesting Polypore (Hapalopilus rutilans) poisoning: report of two cases.

INTRODUCTION: Only four cases of Hapalopilus rutilans poisoning have been previously published. We report two new cases. CASE REPORTS: A father and his 13-year-old daughter picked mushrooms identified as Fistulina hepatica specimens and ate an unknown quantity (Hour 0). At Hour 12 post-ingestion, both subjects complained of abdominal pain, then nausea, vomiting, anorexia, asthenia, diplopia, and blurred vision. The father also had visual hallucinations. On Day 2 post-ingestion, clinical examination showed multidirectional nystagmus. The father also had balance disorders and both subjects emitted purple urine. Laboratory tests showed elevated serum creatinine and blood urea levels, proteinuria and leukocyturia in both subjects, and mild elevation of hepatic enzymes in the father. Urine color returned to normal on Day 2 and Day 7 post-ingestion in the girl and her father, respectively. Complete clinical and biochemical recovery was obtained within one week in both cases. DISCUSSION: Signs and symptoms are similar to those previously reported after H. rutilans ingestion. This mushroom can be easily confused with F. hepatica. Purple discoloration of the urine after ingestion of a polyporic mushroom is highly suggestive of H. rutilans poisoning. Polyporic acid is probably the active toxin.
