Successful lectin-separated bone marrow transplantation in adenosine deaminase deficiency-related severe immunodeficiency.
Severe combined immunodeficiency disease (SCID) with adenosine deaminase (ADA) deficiency is a genetic autosomic recessive disorder with profound impairment of T-cell function, invariably complicated by fatal infections. The absence of ADA-enzyme and the accumulation of deoxy-ATP, with toxic effects on the T-lymphocytes is the common feature of this disease. As a consequence, lymphoid precursors failure to develop into mature T-cells, resulting in absolute lymphopenia and atrophy of the thymus. Bone marrow transplantation from an HLA-identical donor is considered the treatment of choice for this disease. We describe the case of a 1-month-old child with ADA deficiency SCID who underwent bone marrow transplantation (BMT) using paternal haploidentical, lectin-separated marrow, as a source of hemopoietic stem cells.
