Niemann-Pick foamy cells

Sphingomyelinase deficiency

At this time, there is no effective treatment for Type A.

Bone marrow transplantation has been performed on a few patients with Type B with encouraging results. Researchers continue to study possible treatments, including enzyme replacement therapy and gene therapy.

There is no specific treatment for Type D. Recently a new treatment called miglustat has been approved for type C.

A healthy, low-cholesterol diet is recommended, although research into low-cholesterol diets and cholesterol-lowering drugs does not show that these methods stop the disease from getting worse or change how cells break down cholesterol. However, medicines are available to control or relieve many symptoms, such as cataplexy and seizures.
