Bone marrow transplantation has been undertaken with encouraging results as therapy for a wide variety of lysosomal storage diseases. We report a case of
Niemann-Pick disease
Type IA in which, despite the presence of only mild hypotonia with depressed reflexes, the clinical course of the disease appeared to be only slightly modified by this procedure, which was performed at the earliest practical opportunity. The patient was diagnosed early when asymptomatic, because of a family history of an affected sibling who died at 14 months. He received a bone marrow transplant from an HLA-identical, MLC non-reactive sibling donor, whose leukocyte sphingomyelinase activity was in the homozygote normal range. There was adequate engraftment as evidenced by persistently normal leukocyte sphingomyelinase activities, and there was no evidence of
graft-versus-host disease
. Visceral storage and neurological impairment were less rapidly progressive than in his untreated sibling but he eventually died at 30 months. Autopsy confirmed that this was essentially due to the effects of the underlying
Niemann-Pick disease
. We conclude that despite some success in other neurovisceral lysosomal storage disorders, bone marrow transplantation is not likely to be an adequate treatment for
Niemann-Pick disease
Type IA.

Graft-versus-host disease
(
GVHD
), graft rejection, disease recurrence and long-term toxicity remain significant obstacles to successful allogeneic bone marrow transplantation (BMT) in children with genetic diseases. In an attempt to improve results, we used a preparative regimen consisting of three alkylating agents, busulfan (BU), thiotepa (TTP) and cyclophosphamide (CY), for T cell-depleted allogeneic bone marrow transplantation instead of the conventional BU-CY protocol. The effect of this intensified regimen was investigated in 26 consecutive children with genetic diseases who underwent T cell-depleted BMT from HLA-identical siblings. Sixteen patients were males and 10 females, of median age 5 (0.2-14) years. The diseases included beta-thalassemia major, osteopetrosis, severe combined immunodeficiency, Wiskott-Aldrich syndrome, familial agranulocytosis, congenital idiopathic hemolytic anemia (CIHA), Gaucher's disease,
Niemann-Pick disease
, Hurler's syndrome, and adrenoleukodystrophy. The conditioning regimen consisted of BU 4 mg/kg x 4 days (-8 to -5), TTP 5 mg/kg x 2 days (-4 and -3), and CY 60 mg/kg x 2 days (-2 and -1). Engraftment was as expected, with WBC >1.0 x 10(9)/l at day +19 (10-33), ANC >0.5 x 10(9)/l at day +22 (10-56) and platelets >25 x 10(9)/l at day +32 (18-131). Transplant-related mortality was 19%. Overall survival and disease-free survival (DFS) at 60 months follow-up were both 77%. Our results with the BU-TTP-CY regimen followed by T cell-depleted BMT in genetic diseases may provide a basis for prospective comparison with the standard conditioning regimen of BU-CY in the management of children suffering from these conditions.

Of the various gene therapy approaches under investigation for the treatment of genetic diseases, hematopoietic stem cell-mediated gene therapy has attracted the most interest. Enriched populations of hematopoietic stem cells can be obtained from diseased individuals, genetically modified to express normal gene products, and then transplanted back into these individuals without the risk of
graft versus host disease
. Following transplantation and engraftment, hematopoietically-derived cells can repopulate various sites of pathology and express the normal gene product in vivo. Such a procedure has been accomplished in several mouse models of human genetics diseases, leading to partial or complete correction of the disease phenotype, and current efforts are now focused on adapting the success of murine systems to larger animals, including man. This review will focus on the use of hematopoietic stem cell-mediated gene therapy for the treatment of lysosomal storage disorders, and discuss recent data obtained in the laboratory using a murine knock-out mouse model of Types A and B
Niemann-Pick disease

Allogenic bone marrow transplantation (BMT) was carried out on a 3-year-old white caucasian girl with
Niemann-Pick disease
(
NPD
) type B. The donor was her unaffected brother. The patient was neurologically normal at the time of transplantation. Engraftment was based on cytogenetic studies and increased leukocyte acid sphingomyelinase (ASM) activity. However, liver biopsies taken up to 33 months post transplantation showed only a moderate reduction in stored sphingomyelin and no significant increase in ASM activity. The post-transplantation period was complicated by severe
graft-versus-host disease
and a respiratory arrest. By 6 years of age, neurological involvement was observed, including bilateral cherry red spots. The proband is now severely mentally and physically disabled. Liver cirrhosis has continued to progress despite the BMT, and haematemesis due to portal hypertension occurred at 17 years of age. However, pulmonary infiltration regressed after BMT and there has been no clinical evidence of pulmonary insufficiency.

From March 1991 through 31st December 2007, 2042 patients underwent stem cell transplantation at the Hematology-Oncology and Stem Cell Transplantation Research Center, affiliated to Tehran University of Medical Sciences. These transplantations included 1405 allogeneic stem cell transplantation, 624 autologous stem cell transplantation, and 13 syngeneic stem cell transplantation. Stem cell transplantation was performed for various diseases including acute myelogenous leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic lymphoblastic leukemia, thalassemia major, sickle cell thalassemia, sickle cell disease, multiple myeloma, myelodysplasia, mucopolysaccharidosis, paroxysmal nocturnal hemoglobinuria, non-Hodgkin's lymphoma, Hodgkin's disease, severe aplastic anemia, plasma cell leukemia,
Niemann-Pick disease
, Fanconi anemia, severe combine immunodeficiency, congenital neutropenia, leukocyte adhesion deficiencies, Chediak-Higashi syndrome, osteopetrosis, histiocytosis X, Hurler syndrome, amyloidosis, systemic sclerosis, breast cancer, Ewing's sarcoma, testicular cancer, germ cell tumors, neuroblastoma, medulloblastoma, renal cell carcinoma, nasopharyngeal carcinoma, ovarian cancer, Wilms' tumor, rhabdomyosarcoma, pancreatoblastoma, and multiple sclerosis. We had 105 cellular therapies for postmyocardial infarction, multiple sclerosis, cirrhosis, head of femur necrosis, and renal cell carcinoma. About 30 patients were retransplanted in this center. About 74.9% of the patients (1530 of 2042) remained alive between one to 168 months after stem cell transplantation. Nearly 25.1% (512 of 2042) of our patients died after stem cell transplantation. The causes of deaths were relapse, infections, hemorrhagic cystitis,
graft versus host disease
, and others.
