In patients that developed a chronic renal failure the augmentation in tryptophan degradation is reflected in the increase in plasma metabolites of kynurenine pathway. Hemodialysis is one of therapeutic approaches that significantly reduce all plasma kynurenine metabolites in uremic patients.

Idiopathic pulmonary fibrosis is thought to involve lung injury caused by reactive oxygen species (ROS), which in turn is followed by abnormal fibrosis. A transforming growth factor (TGF)-β1-induced increase in myofibroblast number plays an important role in this abnormal fibrosis.
