Abstract Background Mutations in the mitochondrial transfer RNA (mt-tRNA) gene are a hotspot for DNA (mtDNA) mutations and most common diseases. Methods We identified mt-tRNA 5816 A > G (m.5816 G) mutation 3-year-old child with dystonia who died. performed clinical evaluation, genetic analysis, biochemical investigation function testing. Results Our patient was found to have hyperlactatemia....

During a 6-and-a-half month period, we identified 10 human immunodeficiency virus (HIV)-infected men who were receiving antiretroviral regimens, including nucleoside analogues, and who developed unexplained reproducible hyperlactatemia in association with either abdominal symptoms or an unaccounted-for elevated alanine aminotransferase level, or both. After careful consideration of the possible...

Methods Single centre cohort study. All adult patients admitted to the medical emergency ward of Odense University Hospital from March 2009 to August 2011, who had an arterial blood gas sample taken within six hours after admission were enrolled. Lactate was stratified in 1mmol/l (mM) intervals. Ten-day mortality after admission was assessed through the Danish Centralised Civil Registration sys...

Tumor necrosis factor alpha (Tnf) plays a pleiotropic role in murine malaria. Some investigations have correlated Tnf with hypothermia, hyperlactatemia, hypoglycemia, and a suppression of the erythropoietic response, although others have not. In this study, we have evaluated parasitemia, survival rate and several pathological features in C57BL/6JTnf(-/-) and C57BL/6JTnf(+/+) mice after infectio...

Lactic acidosis in patients infected with the human immunodeficiency virus was initially identified as a rare complication of therapy with nucleoside analog reverse transcriptase inhibitors (NRTIs). The only patient group that appears to be at greater risk is pregnant women. More recently, milder elevations in lactate (i.e., lactic acidemia or hyperlactatemia) have been found to be more common ...

Recently, propranolol was suggested to prevent hyperlactatemia in a child with hypovolemic shock through β-adrenergic blockade. Though it is a known inhibitor of glycolysis, propranolol, outside this observation, has never been reported to fully protect against lactate overproduction. On the other hand, literature evidence exists for a cross-talk between β-adrenergic receptors (protein targets ...

Since stroke in childhood, although rare, has many potential causes, identification of the underlying disease offers a diagnostic challenge. Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a rare disorder often mistaken for other diseases. Here, we describe the case of a previously healthy 11-year-old girl who initially presented with gastroenteritis...
