No published case of Wolman's disease has described the prenatal sonographic findings. We present a case in which a third-trimester sonographic examination demonstrated fetal hepatomegaly and bilateral adrenal echogenicity suggestive of diffuse calcification. Wolman's disease, also known as lysosomal acid lipase (LIPA) deficiency, is a rare autosomal-recessive disorder characterized by complete absence of the LIPA enzyme. The diagnosis of Wolman's disease was made postnatally by biochemical testing, which indicated absence of LIPA enzyme activity and gene sequencing, which confirmed homozygosity for the G66V mutation within the LIPA gene. © 2017 Wiley Periodicals, Inc.

Lysosomal acid lipase deficiency (LAL-D) is an ultra-rare lysosomal storage disease with two distinct phenotypes, an infantile-onset form (formerly Wolman disease) and a later-onset form (formerly cholesteryl ester storage disease). The objective of this narrative review is to examine the most important aspects of the diagnosis and treatment of LAL-D and to provide practical expert recommendations. The infantile-onset form occurs in the first weeks of life and is characterized by malnourishment and failure to thrive due to gastrointestinal impairment (vomiting, diarrhea, malabsorption), as well as systemic inflammation, hepatosplenomegaly, and adrenal calcifications.

Lysosomal acid lipase deficiency (LAL-D) is an autosomal recessive genetic disease arising from mutations in the lipase A, lysosomal acid type (LIPA) gene, characterised by the formation of cholesterol esters and triglyceride storages, primarily in the liver and spleen. By analysing the level of lysosomal acid lipase (LAL), two forms were described in the literature: Wolman disease and cholesteryl-ester storage disease (CESD). Wolman disease usually manifests with rapidly progressive symptoms within the first year of life, while CESD is a latent condition, with significant features appearing later in life.

Lysosomal acid lipase deficiency (LAL-D) is caused by mutations in the LIPA gene, which encodes the lysosomal enzyme that hydrolyzes triglycerides and cholesteryl esters to free fatty acids and free cholesterol. The objective of this study was to develop a curative single-treatment therapy for LAL-D using adeno-associated virus (AAV). Treatment at both early (1-2 days) and late (8-week) timepoints with rscAAVrh74.

Lysosomal acid lipase (LAL) is the only known enzyme that degrades cholesteryl esters and triglycerides at an acidic pH. In LAL deficiency (LAL-D), dysregulated expression of matrix metalloproteinase 12 (MMP-12) has been described. The overexpression of MMP-12 in myeloid lineage cells causes an immune cell dysfunction resembling that of knockout ( KO) mice.

Article Synopsis
- The study examined the occurrence and characteristics of callosal injury in fetuses affected by cytomegalovirus (CMV) fetopathy using a retrospective analysis of patients with confirmed CMV-PCR.
- Among 72 patients, 34.7% showed callosal abnormalities, primarily associated with other central nervous system issues like periventricular hyperechogenicity and calcifications.
- The findings suggest that callosal injury is a common consequence of CMV infection, indicating a worse prognosis and increased risk of neurodevelopmental impairment, with distinct prenatal patterns of injury compared to what is seen postnatally.
