Abstract
BACKGROUND

Cochineal red is an organic compound widely used in food, cosmetics, pharmaceuticals, textiles, and other fields due to its excellent safety profile. Poisoning caused by eating foods containing cochineal red is rare, and repeated atrial arrhythmia due to cochineal red poisoning is even rarer.

CASE SUMMARY

An 88-year-old Asian female patient was admitted to hospital due to a disturbance of consciousness. Twelve hours prior to presentation, the patient consumed 12 eggs containing cochineal red over a period of 2 h. At presentation, the patient was in a coma and had a score of 6 on the Glasgow Coma Scale (E2 + VT + M4). The patient’s skin and mucous membranes were pink. Electrocardiography (ECG) revealed rapid atrial fibrillation without any signs of ischemia. We prescribed cedilan and fluid replacement for arrhythmia correction. Shortly after admission, the atrial fibrillation corrected to a normal sinus rhythm. On the day 2 of admission, the patient had a sudden atrial flutter accompanied by hemodynamic instability and rapidly declining arterial oxygen saturation between 85% and 90%. The sinus rhythm returned to normal after two electrical cardioversions. Six days after admission, the skin color of the patient returned to normal, and the ECG results were normal. The patient was transferred out of the intensive care unit and eventually discharged after 12 d in hospital. At the 2-mo follow-up visit, the patient was in good health with no recurrence of arrhythmia.

CONCLUSION

Although cochineal red is a safe, natural food additive, excessive consumption or occupational exposure can induce cardiac arrhythmias.

Keywords: Cochineal red, Poisoning, Cardiac arrhythmias, Atrial fibrillation, Atrial flutter, Case report

Core Tip: Poisoning caused by eating foods containing cochineal red is rare, and repeated atrial arrhythmia caused by cochineal red poisoning is even rarer. For the first time, we report a case of repeated atrial arrhythmia caused by cochineal red poisoning. Through this case report, clinicians and the public will gain knowledge of the risks of excessive consumption of foods containing cochineal red pigment.
