Liver transplantation (LT) has been adopted as a radical treatment for ornithine transcarbamylase deficiency (OTCD), yielding favorable outcomes. Despite the fact that it is an inheritable disease, a blood relative who is heterozygous for the disorder must sometimes be used as a liver donor for
Urea cycle deficient patients with prominent hyperammonemic often exhibit abnormal production of nitric oxide (NO), which reduces vascular tone, along with amino acid abnormalities. However, information related to the metabolic changes in heterozygotes of ornithine transcarbamylase deficiency (OTCD)
Cerebral edema remains a significant cause of morbidity and mortality in patients with acute liver failure (ALF) and has been linked to elevated blood ammonia levels. l-ornithine phenylacetate (OPA) may decrease ammonia by promoting its renal excretion as phenylacetylglutamine (PAGN), decreasing the
Nitric oxide (NO) levels in plasma and urine were determined in 5 girls with ornithine transcarbamylase deficiency (OTCD) of late-onset type, who often developed migraine-like headache or vomiting. The patients were found to have low NO synthesis, suggesting that the low NO synthesis contributes to
OBJECTIVE
To describe three female patients of one family with different phenotypes of the same mutation of the ornithine transcarbamylase gene. X-linked inherited ornithine transcarbamylase deficiency is the most frequent urea cycle disorder. Many of the hemizygous males die during the neonatal
We report a 17-year-old female case of ornithine transcarbamylase (OTC) deficiency who died of brain edema due to hyperammonemic attack. The patient had a brother with OTC deficiency who had died of hyperammonemia at 17 years of age. She firstly had a symptom of headache, nausea, vomiting and
BACKGROUND
Ornithine transcarbamylase (OTC) deficiency is the most frequent innate disorder of the urea cycle and is X-chromosome linked. The disease normally manifests itself shortly after birth and is fatal when untreated. Due to the different expression and X-chromosomal inheritance the
Ornithine transcarbamylase (OTC) deficiency is an X-linked disorder of urea synthesis. Among females who carry a mutant OTC allele, there is a wide range of phenotypic variability, ranging from apparent normality to a severe onset and the resulting profound neurologic impairment observed in
Stroke is one of the leading causes of disability all over the world. However, biomarkers for fast differential diagnosis of acute ischemic stroke (AIS) from vertigo or headache, remains lacking. Using a direct-infusion mass spectrometry method, it is possible to establish an efficient method for
OBJECTIVE
To investigate the incidences of urea cycle defects (UCDs) in the patients with hyperammonemia and study their etiology, clinical and laboratory features.
METHODS
In the past 7 years, 26 cases (10.2%) of UCDs were detected from 254 patients with hyperammonemia. The etiological diagnoses
Lactic acid bacteria (LAB) can produce a huge amount of bioactive compounds. Since their elective habitat is food, especially dairy but also vegetal food, it is frequent to find bioactive molecules in fermented products. Sometimes these compounds can have adverse effects on human health such as
