Heterozygous liver transplantation for maple syrup urine disease: First European reported case.

MSUD is an autosomal recessive metabolic disorder that results from a defect in the BCKDH enzyme. This enzyme is essential for the second step in the metabolism of the branched-chain amino acids, leucine, isoleucine, and valine. Patients with MSUD are subject to severe, irreversible neurologic injury unless closely managed with a specialized metabolic formula and a diet restricted in leucine throughout their lifetime.

The phenotypic spectrum of organic acidurias and urea cycle disorders. Part 2: the evolving clinical phenotype.

Background: The disease course and long-term outcome of patients with organic acidurias (OAD) and urea cycle disorders (UCD) are incompletely understood.

Aims: To evaluate the complex clinical phenotype of OAD and UCD patients at different ages.

Results: Acquired microcephaly and movement disorders were common in OAD and UCD highlighting that the brain is the major organ involved in these diseases.

Plasma citrulline levels in preterm neonates with necrotizing enterocolitis.

Background And Aim: Citrulline is a non-protein amino acid synthesized in the small intestine. In children with short-bowel syndrome, citrulline has served as a reliable marker of the residual bowel length and parenteral nutrition (PN) independence. In the present study we aim to assess the value of citrulline measurement in preterm neonates developing necrotizing enterocolitis (NEC).

Plasma citrulline levels in paediatric patients with celiac disease and the effect of a gluten-free diet.

Objective: Citrulline is a nonprotein amino acid synthesized in the small intestine. The aim of this study is to explore plasma citrulline levels in children with celiac disease (CD) and monitor the time-related changes of these levels after initiation of a gluten-free diet (GFD).

Methods: Fasting-plasma citrulline levels were determined by high-performance liquid chromatography in (i) 23 patients with CD before the institution of GFD, (ii) 20 patients with CD under treatment for more than 2 years responsive to a GFD, (iii) 10 children with gastrointestinal symptoms and normal small bowel biopsy, and (iv) 20 healthy controls.
