Insights

Pregnancies complicated by fetal long-chain 3-hydroxyacyl coenzyme A dehydrogenase (LCHAD) deficiency can cause maternal liver issues like fatty liver and HELLP syndrome. Unaffected babies were born to mothers without these complications, suggesting fetal LCHAD status impacts maternal health.

Area of Science:

  • Biochemistry
  • Genetics
  • Maternal-Fetal Medicine

Background:

  • Long-chain 3-hydroxyacyl coenzyme A dehydrogenase (LCHAD) deficiency is an inherited metabolic disorder.
  • Maternal complications during pregnancy, such as fatty liver and HELLP syndrome, can pose significant risks.

Purpose of the Study:

  • To investigate the association between fetal LCHAD deficiency and maternal liver complications during pregnancy.
  • To determine if fetal LCHAD status influences the occurrence of adverse maternal outcomes.

Main Methods:

  • Case series reporting on eleven pregnancies across 5 mothers.
  • Clinical observation of maternal and fetal health outcomes, including liver function and specific syndrome development.

Main Results:

  • Six pregnancies involving fetuses with LCHAD deficiency were complicated by maternal fatty liver and HELLP syndrome.
  • Three pregnancies resulted in unaffected babies, with these pregnancies being largely uncomplicated.
  • Adverse maternal effects segregated with fetal LCHAD deficiency status, not solely maternal heterozygosity.

Conclusions:

  • Fetal LCHAD deficiency may adversely affect maternal liver function during pregnancy.
  • Maternal heterozygosity alone does not explain the observed adverse effects; fetal status is critical.

Overview of Fatty Acid Metabolism

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
