LAL Deficiency (Lysosomal Acid Lipase Disease) & Wolman Disease patient support
Tags:
Hi Karen! We have been looking for an answer to your question about fat storage in CESD and Wolman's Disease. We are going to be asking a team of medical experts your question very soon! Thank you for your patience:) Mary
This answer comes to us from Anthony Porto, a pediatric gastroenterologist and hepatologist at Yale University.
Patients with Wolman’s and CESD have a low level (as in CESD) or lack of LAL (as in Wolman’s disease). Loss or decrease in LAL leads to a build-up of fats called triglycerides and cholesterol esters (cholesterol ester is cholesterol which is linked to a fatty acid molecule)in the lysosomes of the cells. Because these fats get ‘stuck’ in the lysosomes, the cells think that it is deficient in cholesterol and begin to make more of it. This leads to a build-up in fat in the liver as more cholesterol is made, and leads to a fatty and enlarged liver. Accumulating fat leads to liver damage and eventually cirrhosis. It is sometimes difficult with imaging studies such as an ultrasound to differentiate a fatty liver from someone who is overweight from someone who has CESD or Wolman’s. Livers of patients with CESD and Wolman’s may have an orange appearance because of the extra fat in the liver. A healthy, normal weight person should not have accumulation of fat and their liver will not have accumulation of fat on imaging studies as there is a balance in fat production, transport and use.
Thank you so much for sharing this information Mary - every little bit helps. I am learning more and more as time passes by.

Hi Karen, I am very happy that your daughter is doing so much better. I also have CESD and it is very scary being diagnosed and just not knowing. I thank my lucky starts for this site and the people on here. I myself am working on the diet and will see what comes of it. As of now I am trying to treat the complictions arising from the CESD.
Sincerely,
Melissa
