| chronic active hepatitis | <pathology> This is a form of continuing liver inflammation that results in liver cell death. Causes include viral infection (hepatitis D, hepatitis B, hepatitis C), autoimmune disease, drug ingestion or metabolic causes. Chronic active hepatitis will lead to hepatic failure and death in a small percentage of these patients. (27 Sep 1997) |

| chronic allograft rejection | Immunologically mediated damage to the allograft, typically a kidney allograft, manifested by diffuse interstitial fibrosis glomerular changes, typically membranous and sclerotic in nature, as well as intimal fibrosis of the blood vessels with tubular atrophy and loss of tubular structures.

| chronic atrophic polychondritis | A degenerative disease of cartilage producing a bizarre form of arthritis, with collapse of the ears, the cartilaginous portion of the nose, and the tracheobronchial tree; death may occur from chronic infection or suffocation because of loss of stability in the tracheobronchial tree of autosomal origin. Synonym: chronic atrophic polychondritis, generalised chondromalacia, Meyenburg's disease, Meyenburg-Altherr-Uehlinger syndrome, relapsing perichondritis, systemic chondromalacia, von Meyenburg's disease.
