Over the last 15 years, important research has expanded our knowledge of the clinical, molecular genetic, and biochemical features of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). The characterization of mitochondrial involvement in this disorder and the seminal determination of its genetic cause, have opened new possibilities for more(More)
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is caused by mutations in the thymidine phosphorylase gene (ECGF1). We present the first detailed report of a Brazilian MNGIE patient, harboring a novel ECGF1 homozygous mutation (C4202A, leading to a premature stop codon, S471X). Multiple deletions and the T5814C change were found in(More)
INTRODUCTION Knowledge of the social changes related to HIV infection can be helpful in the attempts to design more effecting preventive strategies for this disease. The aim of this study was assess the progress that has occurred in the knowledge, attitudes and habits of the general population in relation to HIV infection between 1997 and 2005. METHODS(More)
We studied a patient with the cardinal features of mitochondrial gastrointestinal encephalomyopathy (MNGIE). Two of his siblings showed a similar clinical picture. Muscle histochemistry displayed ragged red fibres (RRF) which were COX negative and biochemistry revealed combined defects of complexes III and IV of the mitochondrial respiratory chain.(More)
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is caused by thymidine phosphorylase (TP) deficiency, which leads to toxic accumulations of thymidine (dThd) and deoxyuridine (dUrd). In this work, we report that infusion of platelets from healthy donors to patients with MNGIE restored transiently circulating TP and reduced plasma dThd and dUrd(More)
