title: Bone marrow transplantation in Batten disease (neuronal ceroid-lipofuscinosis). Will it work? Preliminary studies on coculture experiments and on bone marrow transplant in late infantile Batten disease.
abstract: Lymphocytes from a patient with preclinical late infantile Batten disease were cultured alone and with lymphocytes from donors, and the fate of the curvilinear inclusions characteristic of the disease was monitored by electron microscopy. There was no evidence of transfer of deficient enzyme or factor that might have caused removal of the stored material, and the curvilinear profiles remained in the cultured cells without signs of degradation. Cells stimulated to divide with phytohaemaglutinin did not exhibit storage in culture suggesting that storage is a function of the age of the cell. The patient received a bone marrow transplant at 2 7/12 years while still clinically unaffected, and the effect on lymphocytes and cells in skin and rectal biopsies was monitored by electron microscopy over a period of 9 months until the donor marrow became displaced by the host cells. He has had one seizure and now has neurophysiological evidence of late infantile Batten's disease. Bone marrow transplant may have no effect on material already stored but might prevent further build-up and halt the onset of the clinical symptoms although very recent studies on early (fetal) transplants in sheep with a form of Batten disease have shown no benefit.
