Filter by:The purpose of this study is to investigate whether entecavir treatment increases the incidence of lactic acidosis compared to another nucleoside/nucleotide reverse transcriptase inhibitors (NRTI), lamivudine, and/or no NRTI treatment, in patients with cirrhosis or hepatic failure whose Model for End stage Liver Disease (MELD) scores are over 18.
Blood lactate levels in patients receiving typical or atypical antipsychotics have not been described in the literature. The goal of this study is to assess the dynamics of lactate levels in the blood from typical or atypical antipsychotics not confounded by prior antipsychotic treatments, the investigators conducted a prospective study of lactate levels in patients receiving antipsychotic medication. The investigators hypothesized that 6 months of treatment with haloperidol or olanzapine would result in a change in blood lactate levels and extrapyramidal side effects.
Metformin is the first line drug of choice for the treatment of type II diabetes. Lactic acidosis can develop as a side effect, especially when renal failure leads to drug accumulation. Lactic acidosis is usually attributed to an abnormal inhibition of hepatic lactate clearance. Growing evidence suggest that metformin can dose-dependently inhibit hepatocyte mitochondrial function. Whether a similar effect occurs in extra-hepatic human tissues remains unknown. The investigators hypothesize that mitochondrial dysfunction occurs during metformin intoxication even in tissues other than the liver, thus contributing to the development of lactic acidosis. The aim of this study is to investigate mitochondrial integrity in circulating platelets of patients with lactic acidosis due to metformin intoxication.
The 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.
Lactic acidosis is a potentially life-threatening disease associated with the treatment of chronic HIV infection. Although acidosis is rare, hyperlactatemia is common and may have long term consequences yet to be recognized. Lactic acidosis is a manifestation of mitochondrial toxicity; consequences which have yet to be fully recognized and understood. In this study, we propose to look at lactate clearance and production by two methods, in four treatment groups, including HIV positive subjects on highly active antiretroviral therapy (HAART) treatment regimes and without HAART regimes, with liver steatosis and without, and compared with HIV negative controls. Supplementation with cofactors thiamine, niacin and L-carnitine, which may have a positive effect on lactate metabolism by facilitating mitochondrial function, will be studied as well.
Dichloroacetate (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.
OBJECTIVES: I. Determine the pharmacokinetics of sodium dichloroacetate (DCA) in patients with congenital lactic acidemia. II. Determine the efficacy of DCA in decreasing the frequency and/or severity of acute episodes of acidotic illness, improving linear growth, improving neurological or developmental function, or slowing neurological or developmental deterioration in these patients.
OBJECTIVES: I. Compare the safety of sodium dichloroacetate (DCA) vs placebo in children with congenital lactic acidosis. II. Determine the quality of life of these patients. III. Determine the pharmacokinetics and metabolic fate of DCA over the course of drug administration in these patients.
OBJECTIVES: I. Study the metabolism of pyruvate and related problems in patients with lactic acidemia. II. Define the nature of the metabolic defect.
