Treatment
Medical Care
At present, no specific treatment is available for patients with any Niemann-Pick disease (NPD) subtypes, and treatment is symptomatic.
- Orthotopic liver transplantation in an infant with type A disease and amniotic cell transplantation in several patients with type B disease have been attempted with little or no success.
- Bone marrow transplantation in a patient with Niemann-Pick disease type B was successful in reducing spleen and liver volumes, the sphingomyelin content of the liver, the number of Niemann-Pick cells in the marrow, and infiltration of the lungs detected radiologically. However, no long-term information is available because the patient died 3 months after transplantation.
- To date, lung transplantation has not been performed in any patient with type B disease who was severely compromised.
- Future prospects for treatment of patients with Niemann-Pick disease type B include enzyme replacement and gene therapies.
- No specific treatment has been identified for patients with type A disease. Some patients have undergone stem cell transplantation, but reports of the outcomes have not yet occurred.
Surgical Care
- Although patients may have massive splenomegaly, splenectomy should be avoided whenever possible because removal of the spleen is accompanied by deterioration of pulmonary status, which is caused by increased storage of sphingomyelin in the lung parenchyma.
Consultations
- Geneticist: Evaluation and ongoing care by a trained metabolic geneticist should occur.
- Pulmonologist: Patients with Niemann-Pick disease type B should undergo annual pulmonary function testing and evaluation.
Diet
- Pediatric patients with Niemann-Pick disease type B require frequent meals to promote growth. Many patients have early satiety because of organomegaly. For some patients, supplements with high levels of kilojoules are useful.
- In patients with Niemann-Pick disease type A, feeding becomes a major difficulty as the disease progresses. Discussion with the family to determine a strategy for providing calories should occur.
Activity
- Patients with type B disease should avoid contact sports because of the risk of splenic rupture.
Medication
- Therapy using medications currently is not a component of the standard of care in patients with Niemann-Pick disease (NPD).
