Recently, it has been suggested that alcohol-induced hyperhomocysteinaemia in patients suffering from chronic alcoholism might be a risk factor for alcohol withdrawal seizures. In the present follow-up study 12 patients with chronic alcoholism who suffered from withdrawal seizures had significantly
OBJECTIVE
To study the clinical features and treatment outcomes of cardiovascular system involvement in children with methylmalonic aciduria combined with hyperhomocysteinemia (MMACHC).
METHODS
The clinical data of 10 children with methylmalonic aciduria combined with hyperhomocysteinemia and who
Background: Disorders of the metabolism and absorption of vitamin B12 can lead to decrease in activity of methionine synthetase and methylmalonate coenzyme A mutase (MMUT), which results in increased levels of methylmalonic acid and
Patients affected by recurrent seizures frequently present increased homocysteine plasma levels in consequence of treatment with antiepileptic drugs. Homocysteine is proconvulsant and can affect the response to antiepileptic drugs. In addition, high homocysteine plasma levels represent a risk factor
Hyperhomocysteinaemia is associated with an increased risk of arterial vascular disease and thrombosis in adults. Our aim was to study the association of hyperhomocysteinaemia and stroke in children. Since some patients who had suffered a stroke developed seizures and received treatment with
A case of combined methylmalonic aciduria and homocysteinemia presenting with hydrocephalus as an early manifestation was reported for its rarity to see and to discuss the relationship between metabolic diseases and hydrocephalus by literature review. The case was an infant with seizures and
A 20-year-old student presented with generalized tonic-clonic seizures and was diagnosed to have cortical venous thrombosis. Her dietary history and the clinical signs of vitamin deficiency prompted further investigations, which detected hyperhomocysteinaemia secondary to vitamin B12 deficiency as a
Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the regulation of plasma homocysteine levels. MTHFR deficiency, an autosomal recessive disorder, results in homocystinuria and hypomethioninaemia and presents with highly variable symptoms affecting many organs but predominantly the
A 63-year-old man was admitted to our hospital because of convulsive seizures. Radiological examinations revealed cerebral venous sinus thrombosis in the anterior part of the superior sagittal sinus. He had marked hyperhomocysteinemia (93.5 nmol/ml) due to combined deficiencies of folate and vitamin
Although a range of neurological and psychiatric disorders are widely reported to be associated with coeliac patients, their pathogenesis remains unclear. Some such disorders are believed to be secondary to vitamin deficiency due to malabsorption, others to immune mechanisms. We hypothesise that
OBJECTIVE
Methylmalonic aciduria (MMA) is a common one of the congenital disorders of organic acids metabolism. Some of the patients with the disorder are complicated with homocysteinemia. Recently, gas chromatography-mass spectrometry (GCMS) has been used to diagnose MMA in China. However, the
There is growing evidence that chronic alcoholism is associated with a derangement in the sulfur amino acid metabolism. Excitatory aminoacids such as glutamate, aspartate, and homocysteine have been shown to be increased in patients with chronic alcoholism who underwent alcohol withdrawal.
Homocysteine (Hcy) is a risk factor for Alzheimer's disease (AD). Bleomycin hydrolase (BLMH) participates in Hcy metabolism and is also linked to AD. The inactivation of the Blmh gene in mice causes accumulation of Hcy-thiolactone in the brain and increases susceptibility to Hcy-thiolactone-induced
Homocystein (Hcy) is regarded as a neuroexcitatory substance, which is therefore used as an epileptogenic agent in experimental epileptology. Experiments "in vivo" as well as "in vitro" revealed its relation to NMDA glutamate receptors, and its potential neurotoxicity. From the clinical aspect,
Severe hyperhomocysteinemia (50-200 microM) often presents itself with acute neuronal dysfunction including seizures and psychosis. Its moderate form (15-50 microM) is associated with cognitive impairment and dementia. We investigated the neuropharmacological effects of homocysteine and its oxidized
