Chronic Graft Versus Host Disease
Reviewed and revised 29 August 2014
- Chronic Graft vs Host Disease is organ dysfunction occurring > 100 days post transplantation
- distinct clinical syndrome from acute GVHD
- pathophysiology poorly understood
- there can be an overlap period, where patients have both acute and chronic GVHD
- affects 50% of HSCT recipients
- chronic GVHD resembles spontaneously occurring autoimmune disorders, e.g. scleroderma
- Organs typically affected: skin (lichenoid and sclerotic rashes), mouth, joints, liver, eyes, gastrointestinal tract, and occasionally lungs
- older patient
- CMV seropositive
- male who receives a stem cell transplant from a multiparous woman
- tissue biopsies of skin, liver and stomach: apoptosis, infiltration of lymphocytes
- investigations to exclude other conditions in the differential diagnosis
- Therapy relies on many of the same medications used to treat acute GVHD
- patients require prolonged immunosuppressive treatment for an average of 2 to 3 years from the initial diagnosis
- Glucocorticoids +/- calcineurin inhibitors (i.e., cyclosporine or tacrolimus) remain the standard initial treatment of chronic GVHD, but the outcomes are often not satisfactory, particularly for patients with high-risk features
- Secondary options unproven: extracorporeal photopheresis, rituximab, sirolimus, mycofenolate mofetil, imatinib, pentostatin and infusion of mesenchymal stem cells
- can worsen survival due to more transplant-related mortality
- infection from immunosuppression and disease-associated immune dysfunction accounts for most deaths
- prolonged treatment is often required (e.g. months-to-years)
- can also have a graft versus tumour effect

He is on the Board of Directors for the Intensive Care Foundation and is a First Part Examiner for the College of Intensive Care Medicine. He is an internationally recognised Clinician Educator with a passion for helping clinicians learn and for improving the clinical performance of individuals and collectives.
After finishing his medical degree at the University of Auckland, he continued post-graduate training in New Zealand as well as Australia’s Northern Territory, Perth and Melbourne. He has completed fellowship training in both intensive care medicine and emergency medicine, as well as post-graduate training in biochemistry, clinical toxicology, clinical epidemiology, and health professional education.
He is actively involved in in using translational simulation to improve patient care and the design of processes and systems at Alfred Health. He coordinates the Alfred ICU’s education and simulation programmes and runs the unit’s education website, INTENSIVE. He created the ‘Critically Ill Airway’ course and teaches on numerous courses around the world. He is one of the founders of the FOAM movement (Free Open-Access Medical education) and is co-creator of litfl.com, the RAGE podcast, the Resuscitology course, and the SMACC conference.
His one great achievement is being the father of three amazing children.
