Hematopoietic Stem Cell Transplantation for Storage Disorders: Present Status

Area of Science:

• Biochemistry
• Genetics
• Pediatrics

Background:

• Storage disorders are inborn errors of metabolism affecting multiple systems, often with severe neurological symptoms.
• Current treatments include enzyme replacement, substrate reduction, gene therapy, and hematopoietic stem cell transplantation (HSCT).
• Neurological manifestations pose significant challenges in managing these lysosomal storage diseases.

Purpose of the Study:

• To review the evidence supporting hematopoietic stem cell transplantation (HSCT) for various storage disorders.
• To evaluate the suitability of HSCT as a therapeutic option for developing countries.
• To highlight the economic feasibility and improved outcomes of HSCT.

Main Methods:

• Review of current literature on HSCT for storage disorders.
• Analysis of treatment outcomes and economic factors.
• Assessment of HSCT's applicability in resource-limited settings.

Main Results:

• HSCT is a viable, one-time intervention with improving outcomes due to advancements in supportive care.
• Its economic feasibility makes it particularly attractive for lower and middle-income countries.
• Evidence supports HSCT's role in managing multisystemic storage disorders.

Conclusions:

• Hematopoietic stem cell transplantation (HSCT) is a promising therapeutic strategy for storage disorders.
• HSCT's cost-effectiveness and improving success rates make it suitable for global application, especially in developing regions.
• Further research and implementation are encouraged to broaden access to this life-changing therapy.
