ABSTRACT
PURPOSE OF STUDY: This study focuses on the search for a suitable related HLA-matched donor of haematopoietic stem cells in the context of allogeneic transplantation in Morocco. The aim of this work is to establish whether the related donor can meet graft needs in Moroccan patients. PATIENTS AND METHODS: 429 families (429 recipients and 965 donors) benefited from HLA typing, using microlymphocytotoxicity, polymerase chain reaction-sequence specific primer and/or high-resolution polymerase chain reaction-specific sequence oligonucleotide. RESULTS: The recipients and donors are mostly men over 18 years of age. In total, 86.8% of the recipients have between 1 and 3 donors who are 96% of the collaterals. Malignant haemopathies account for 54% of allograft indications. Benign haemopathies are more frequent than malignant in children, whereas the profile is reversed in adults. Fifty percent of recipients have an HLA identical donor in their siblings and 42% and HLA haplo identical donor. The HLA typing of the recipients and the donors reveals very large polymorphism of the population. CONCLUSION: The related donor of haematopoietic stem cells represents an important source of grafts but will not be able to satisfy all the needs of Morocco. The creation of national unrelated voluntary donors will open up new possibilities for recipients who do not have a compatible donor within his relatives.
