Lactic Acidosis During and After Seizures
EpilepsyThis project looks at the time course of lactic acid rise (if any) after seizures. Salivary and capillary lactic acid are tested. This type of measurement may be useful in signalling the occurrence or recent history of a seizure.
Pharmacotoxicology of Trichloroethylene Metabolites
Congenital Lactic AcidosisTo establish the relationship between human MAAI haplotype and DCA and tyrosine metabolism. This aim test the postulates that MAAI haplotype determines, and thus can predict,1) dose-dependent DCA kinetics and biotransformation.
Dichloroacetate Kinetics, Metabolism and Toxicology
Lactic AcidosisDichloroacetate (DCA) is a product of water chlorination and a metabolite of certain industrial solvents, thus making it a chemical of environmental concern. However, DCA is also used as an investigational drug for treating various diseases of adults and children, at doses far greater than those to which humans are normally exposed in the environment. Our research involves how DCA is metabolized by healthy adults and by children with a fatal genetic disease, congenital lactic acidosis (CLA) who are treated with DCA.
Study of the Metabolism of Pyruvate and Related Problems in Patients With Lactic Acidemia
Mitochondrial MyopathyMELAS Syndrome1 moreOBJECTIVES: I. Study the metabolism of pyruvate and related problems in patients with lactic acidemia. II. Define the nature of the metabolic defect.
Metformin Treatment, Renal Function and Lactic Acidosis
Type 2 Diabetes MellitusFrom a central registry at the National Board of Health and Welfare in Sweden collect all patients in the city of Malmö prescribed metformin during two years. Glomerular filtration rate (eGFR) was estimated from the CKD-EPI formula (n=5408) and compared to a control material (n=2815) from the same town. All cases of severe lactic acidosis rendering ICU admission were also sought. The study hypothesis is that metformin is prescribed to patients with lower GFR than anticipated with very few cases of lactic acidosis registered.
The Gene Expression Studies of the Role of Tumor Microenvironments in Tumor Progression
HypoxiaLactic AcidosisThe purpose of this study is to analyze the gene expression patterns associated with various microenvironmental stresses in tumors to understand their roles in tumor progression and treatment responses. To achieve this goal, we will perform gene expression analysis of the tumor samples collected from an IRB-approved study (IRB #: 4516-05-2R2) International Phase III Study of Chemoradiotherapy versus Chemoradiotherapy Plus Hyperthermia for Locally Advanced Cervical Cancer directed by Dr. Mark Dewhirst. We will correlate the gene expression signatures of different microenvironmental stresses with the measured physiological parameters to understand their role in tumor progression, treatment response and clinical outcomes.
Dichloroacetate Treatment of Congenital Lactic Acidosis Phase B: Expanded Access
Mitochondrial Enzyme DeficienciesExpanded access to DCA as continued treatment for congenital lactic acidosis.
Study of Metformin Overdose
Metformin Associated Lactic AcidosisThe objective of the METINFO study is an observational single-center retrospective and descriptive study. The main objective is to estimate the real mortality rate associated to a Metformin overdose. Second objectives are to estimate the real hospitalization rate related to metformin overdose and to identify the risk factors of a metformin overdose and especially the potential correlation between metformin blood concentration and overdose severity.
