BACKGROUND
The amino acid l-citrulline is used as a therapeutic agent for urea cycle disorders (UCD) including ornithine transcarbamylase deficiency (OTCD), carbamoyl phosphate synthetase I deficiency (CPSD), and N-acetylglutamate synthase deficiency. There are few reports, however, on the use of
OBJECTIVE
We sought to determine whether serum citrulline (CIT), an amino acid produced by small bowel enterocytes, was associated with clinical and biochemical markers of gastrointestinal function in children undergoing hematopoietic cell transplantation (HCT).
METHODS
We conducted a multicenter,
Cutis laxa (CL) syndromes are connective tissue disorders characterized by redundant, sagging, inelastic and wrinkled skin, with organ involvement. Here, we describe a patient with ALDH18A1-related CL who developed cyclic vomiting. The patient was a 12-year-old boy who presented with poor postnatal
OBJECTIVE
To explore the clinical manifestations and biochemical characteristics of patients with ornithine transcarbamylase deficiency (OTCD) so as to increase the clinician awareness for this disease.
METHODS
The clinical manifestations, blood ammonia levels, citrulline levels, urinary orotic acid
Herein, we describe a case of a now 28-month-old boy who presented at the age of 17 months with four episodes of recurrent vomiting and somnolence during a period of four months with increasing severity. A comprehensive clinical and metabolic evaluation revealed normal blood pH and blood glucose,
Citrullinemia, a rare inborn error of metabolism, is characterized by a deficiency of argininosuccinic acid synthetase that results in large increases in plasma ammonia, citrulline, and glutamine, with normal acid-base balance. The neurologic symptoms vary from poor feeding, vomiting, and
English Pointer puppies were used in experiments designed to assess urea cycle function. A preliminary assay revealed a dietary arginine (Arg) requirement of 0.40% for maximal weight gain of puppies fed a chemically defined L-amino acid diet. Subsequent studies showed that consumption of an Arg-free
OBJECTIVE
To characterize acute radiation syndrome (ARS) sequelae at doses intermediate between the bone marrow (H-ARS) and full gastrointestinal (GI-ARS) syndrome.
METHODS
Male minipigs, approximately 5 months old, 9-12 kg in weight, were irradiated with Cobalt-60 (total body, bilateral gamma
OBJECTIVE
Göttingen minipig (G-MP) displays classic gastrointestinal acute radiation syndrome (GI-ARS) following total body irradiation (TBI) at GI doses which are lethal by 10-14 days. In collaboration with BARDA, we are developing a hemi-body/partial body irradiation (PBI) model by exposing only
In patients undergoing cardiac surgery, both extracorporeal circulation (ECC) and intraoperative mesenterial hypoperfusion may account for increased cytokine levels and lead to postoperative gastrointestinal (GI) symptoms.
We investigated levels of the intestinal damage markers intestinal fatty acid
This study evaluated the safety and efficacy of teduglutide in pediatric patients with short bowel syndrome-associated intestinal failure (SBS-IF).A 24-week, phase III trial with 2 randomized, double-blind teduglutide dose groups and a nonblinded standard Two male siblings presented in the first 6 weeks of life with emesis, diarrhoea, metabolic acidosis and lethargy. A male sibling had previously died at 14 months of age from liver failure of unknown aetiology. Both of the current cases had mild hyperammonaemia with normal orotic acid, organic acid
Argininosuccinate lyase deficiency is a urea cycle disorder which can present in the neonatal period with hyperammonemic encephalopathy, or later in childhood with episodic vomiting, growth and developmental delay. Abnormal hair, hepatomegaly, and hepatic fibrosis are unique features of this
Background : Acetaminophen is a widely used analgesic and antipyretic agent in the pediatric population. While the hepatotoxic effects of the drug have been well recognized in cases of acute overdose and chronic supratherapeutic doses, the toxic effects of acetaminophen are rarely documented in
BACKGROUND
Argininemia is an autosomal recessive inherited disorder of the urea cycle. Because of its atypical symptoms in early age, diagnosis can be delayed until the typical chronic manifestations - including spastic diplegia, deterioration in cognitive function, and epilepsy - appear in later
