Anticholinergic toxicity in a one-year-old male following ingestion of Lupinus mutabilis seeds: case report

ABSTRACT CONTEXT: The seeds from Lupinus mutabilis Sweet, also called "chocho", are an important part of the diet in several countries in South America. Prior to consumption, processing is required to remove toxic alkaloids. These alkaloids are known to have pharmacological properties as antiarrhythmics, antimuscarinics and hypoglycemics. CASE REPORT: We report a case in which a one-year-old male initially presented with altered mental status and respiratory distress and subsequently developed symptoms of anticholinergic toxicity, after ingesting a large amount of chocho seeds. CONCLUSION: In spite of going through a difficult clinical condition, the subject evolved favorably through receiving supportive treatment. The seeds from Lupinus mutabilis provide nutritional benefits when consumed, but people need to know their risks when these seeds are consumed without proper preparation.

[Leguminous plant causes poisoning with anticholinergic syndrome]. / Baljväxt orsakar förgiftning med antikolinergt syndrom.

In this case report we illustrate how incorrectly prepared and cooked seeds from white lupin - a common snack among people from parts of the Mediterranean and Middle East - caused an anticholinergic syndrome in a previously healthy man. The symptoms subsided without treatment and the patient was discharged from the hospital in good health. Anticholinergic syndrome results from inhibition of the parasympatic nervous system. The symptoms commonly include dry mouth, confusion, hallucinations, fever, tachycardia, and urine retention. The syndrome may most frequently be provoked by overdose of drugs such as prometazin, hyoscyamin, and biperidin or by ingestion of plants such as belladonna, datura and henbane. The aim of this report is to increase clinicians' awareness of white lupin's anticholinergic effects.

Dilated pupils, dry mouth and dizziness - a case study.

A man, 44 years of age, presented with a 4 hour history of dizziness, blurred vision, dry mouth and dilated pupils. He was previously well and on no medications and there was no history of recent drug use, head injury or focal neurological symptoms. On questioning, the patient said that he had eaten lupini beans for lunch but that he hadn't had enough time to soak them for long enough before eating them. On examination his Glasgow Coma Score (GCS) was 15/15, heart rate 98 bpm, blood pressure 144/98, temperature 37.8°C and respiratory rate 18 breaths/minute. His skin was warm and dry with dry mucous membranes. His pupils were dilated at 6 mm and were nonreactive. Cardiovascular, respiratory, abdominal and neurological examinations were normal. He was unable to pass urine. Electrocardiogram showed normal sinus rhythm with a rate of 98 bpm.

Anticholinergic toxicity associated with lupin seed ingestion: case report.

We describe a case of acute poisoning in a 51-year-old female patient who presented to the Emergency Department with weakness, anxiety, dry mouth, bilateral mydriasis and lid drop. In differential diagnosis, botulism, Guillain-Barré syndrome and myasthenia gravis were considered, as well as cerebral haematoma because of a cranial injury a week before. Symptoms, which resolved within 12 h without any therapy, were instead related to the ingestion of lupin seeds.
