Brief Summary:
To test whether active pneumococci immunization can alleviate inflammation and improve cholesterol metabolism in lysosomal lipid storage diseases and associated metabolic disorders.

Condition or disease Intervention/treatment Phase
Lipid Metabolism, Inborn Errors Biological: Anti-oxLDL IgM antibody Early Phase 1

Detailed Description:
Growing evidence describes the central role of oxidized low density lipoproteins (oxLDL) in diseases related to lipid metabolism. Moreover, oxLDL has been shown to be involved in pathological processes such as an inappropriate inflammatory response, disturbance of cholesterol metabolism and dysfunction of the lysosomal apparatus. Relevantly, it has been shown that immunizing mice with Streptococcus pneumoniae results in higher serum titers of anti-oxLDL IgM antibodies due to molecular mimicry.
