Donor for BMT with haemoglobin H disease.
We report a successful allogeneic BMT for the treatment of juvenile chronic myelogenous leukemia (JCML) in a 9-month-old Laotian boy using an HLA-matched sibling donor with HbH disease (--SEA/aaCS). In addition, before BMT the recipient had a complex haemoglobinopathy associating heterozygous state AE along with HbH disease (--SEA/-a3,7) without haemoglobin Constant Spring (HbCS). Because various haemoglobinopathies are frequently encountered in southeast Asia, when BMT is performed in Asian families the results may be evaluated by the differing haemoglobin characteristics of recipient and donor. However, there is also a significant risk of transmitting a new haemoglobinopathy to the recipient. Because transplantation from HLA-identical siblings offers the only chance of cure for JCML, the presence of HbH disease with mild clinical expression in the donor should not be taken as a contra-indication to BMT.
