Kynurenine: a role in ME? Kynurenine is "a key metabolite in the tryptophan metabolism, and serves several roles in the immune system and inflammation" - Open Medicine Foundation

Kynurenine is an amino acid that is produced in the body by the metabolism of the essential amino acid tryptophan.[1][2]

ME/CFS[edit | edit source]

The Open Medicine Foundation's ME/CFS Severely Ill, Big Data Study found that patients in the study group with severe ME had one of several defects involving the IDO2 gene, which affected tryptophan - kynurenine metabolism.[3] This lead to the Metabolic Trap theory.[3]

Uppsala trial, Sweden[edit | edit source]

In May 2020, the Open Medicine Foundation announced a pilot treatment trial of kynurenine for ME/CFS.[4] Dr Jonas Bergquist will be running the trial.[5]

Trial type[edit | edit source]

Pilot trial, with cross-over at 3 months. Patients receiving the kynurenine will change to the placebo after 3 months, and patients receiving the placebo will switch to the kynurenine. No control group.[4][5]

Aims[edit | edit source]

To see whether kynurenine improves cognitive impairment (brain fog), headaches and memory in ME/CFS patients.[5]

Patients[edit | edit source]

Only 20 out of a group of 100 ME/CFS patients. Patients will be those identified as having a low level of kynurenine in blood serum and ME/CFS.[5]

Outcomes[edit | edit source]

Measurements will be taken from wearable sensors.[5]
