oGVHD After Bone Marrow Transplantation: a Territory-wide Cohort

Hong Kong500 participantsStarted 2021-04-30

Plain-language summary

Allogeneic Haematopoietic stem cell transplantation (HSCT) is an effective treatment for all array of blood or blood-producing organ disorders. Graft-versus-host-disease (GVHD) occurs as a result of an overactive immunological system against normal host tissues. It can happen in the liver, skin, mucosal surface of the eye, gastrointestinal tract, and genitalia. Ocular GVHD occurs in 30-70% of patients after HSCT. It mainly affects the ocular surface, including the conjunctiva and cornea. In severe cases, multiple clinical manifestations can lead to painful non-healing corneal ulcers, secondary infections, and visual loss. oGVHD can be debilitating and severely impact patients' quality of life. However, there are no widely accepted guidelines available for prevention and management. In collaboration with the Department of Haematology of Queen Mary Hospital, the investigators set out to establish a territory-wide cohort of patients receiving HSCT. Primarily, the investigators aim to establish the population-based epidemiology of oGVHD and understand the natural history and the long-term ophthalmic outcomes of oGVHD via this study.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patient aged 18 or above * Underwent allogeneic HSCT in QMH in the two-year recruitment period Exclusion Criteria: * Underwent autologous HSCT * Patient unable to attend follow-up visits Family Control Subjects The research team will invite an accompanying family member to be the family control. Microbiome and tear samples will be collected for comparison. The sample collection schedule is the same as the corresponding post-HSCT case.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
