Tryptophan in the treatment of carcinoid crisis

Letter to the Editor Carcinoid Tryptophan


A 56-year-old woman was admitted with carcinoid crisis and became comatose. Blood tryptophan at this stage was 5 μg/ml; after treatment with 3.4 g tryptophan daily her level of consciousness improved and blood tryptophan increased to 10 μg/ml. The carcinoid syndrome was not exacerbated by tryptophan. Tryptophan may have a supportive role in the management of carcinoid crisis.
