The following information may help to address your question:
What is Wolman disease?
Wolman disease is a
congenital disease characterized by an impaired metabolism of the fats (lipids). It is the most severe type of
lysosomal acid lipase deficiency.
[1] The lysomal acid lipase deficiency causes a buildup of lipids (fats) in body
organs and calcium deposits in the
adrenal glands. Common symptoms in infants include enlarged liver and spleen, poor weight gain, low muscle tone,
jaundice, vomiting,
diarrhea,
developmental delay,
anemia, and poor absorption of nutrients from food. Wolman disease is caused by
mutations in the
LIPA gene which provides instructions to make the lysosomal acid lipase. Inheritance is
autosomal recessive.
[2] The disease is severe and life-threatening, however
enzyme replacement therapy, available for the treatment of lysosomal acid lipase deficiencies, in the United States, the European Union, and Japan, have shown improvement of symptoms, including liver problems, as well as an increased life expectancy.
[3] Liver transplantation can be considered in some cases when the liver disease is severe. Reports of treatment with
bone marrow transplantation have shown mixed results, correcting the
metabolic disease in a few cases, but not in others.

Is Wolman disease curable?
While there is not a universal cure for all individuals with Wolman disease, some therapeutic options have resulted in correction of the underlying disease process. Studies have shown that children with Wolman disease have had successful early treatment with transplantation of
hematopoietic stem cells (HSCT) and
umbilical cord stem cells.
[5][6] The use of HSCT is controversial as it can be associated with complications. More studies are needed to determine the overall efficacy of these treatment options.

How can I find additional comprehensive information on the treatment of Wolman disease?
You can find relevant journal articles on Wolman
syndrome and its treatment through a service called PubMed, a searchable database of medical literature. Information on finding an article and its title, authors, and publishing details is listed here. Some articles are available as a complete document, while information on other studies is available as a summary abstract. To obtain the full article, contact a medical/university library (or your local library for interlibrary loan), or order it online using the following link. Using "Wolman syndrome[ti] treatment" as your search term should locate articles. To narrow your search, click on the “Limits” tab under the search box and specify your criteria for locating more relevant articles.

The National Library of Medicine (NLM) Web site has a page for locating libraries in your area that can provide direct access to these journals (print or online). The Web page also describes how you can get these articles through interlibrary loan and Loansome Doc (an NLM document-ordering service). You can access this page at the following link
