Types
1- Acute GVHD: Acute GVHD develops within 3 months of the transplantation process, and its symptoms mainly involve the intestines, the skin and the liver.
2- Chronic GVHD: Chronic GVHD is more complex than the acute type, and its symptoms are less defined. It occurs after more than 100 days following transplantation and can virtually occur after years. There is a clinical debate regarding whether or not it follows acute GVHD. So far, cases following acute GVHD, those that didn’t have acute GVHD and even those who had acute GVHD disease and recovered have been reported. The body systems involved are also more diverse and include the eyes, the joints, the gastrointestinal system, the muscles, the nerves and even the lungs.
