Lactate is an essential, versatile metabolic fuel in cellular bioenergetics. In human emergency and critical care, lactate is used as a biomarker and therapeutic endpoint and evidence is growing in veterinary medicine supporting its clinical utility. Lactate production is a protective response providing ongoing cellular energy during tissue hypoperfusion or hypoxia and mitigating acidosis. Hence, hyperlactatemia is closely associated with disease severity but it is an epiphenomenon as the body attempts to protect itself...

Hyperlactatemia predicts mortality in patients with sepsis and septic shock, and its normalization is a potential treatment goal. We investigated the association of blood lactate and its changes over time with 90-day mortality in septic shock. We performed a post hoc analysis of 513 septic shock patients with admission blood lactate measurements in the prospective, observational, multicenter FINNAKI study. Repetitive lactate measurements were available in 496 patients for analyses of change in lactate values during ICU stay...

OBJECTIVES OF THE STUDY: To identify the factors causing high lactate levels in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) and to assess the association between high blood lactate levels and postoperative morbidity and mortality. METHODS: A retrospective observational study including 370 patients who underwent cardiac surgeries under cardiopulmonary bypass. The patients were divided into 2 groups based on serum lactate levels; those with serum lactate levels greater than or equal to 4 mmol/L considered as hyperlactatemia and those with serum lactate levels less than 4 mmol/L...

Mauriac syndrome is a rare disorder that can present with the single feature of glycogenic hepatopathy in children and adults with poorly controlled diabetes mellitus. An often underrecognized finding of glycogenic hepatopathy is lactic acidosis and hyperlactatemia. Primary treatment of glycogenic hepatopathy is improved long-term blood glucose control. Resolution of symptoms and hepatomegaly will occur with improvement in hemoglobin A1C. We present here a case of a young adult female presenting to the intensive care unit with Mauriac syndrome...

South Africa has one of the highest prevalences of HIV and AIDS in the world. HIV/AIDS patients face countless challenges, one of which is the risk of adverse drug reactions (ADRs). This study aimed to describe the ADRs reported in South Africa with reference to the type of ADRs, antiretrovirals (ARVs) implicated, seriousness of the ADRs and patient demographics associated with specific ADRs. A retrospective quantitative study was carried out using ADR reports submitted to the National Department of Health (NDoH) from 1 January 2010 to 31 December 2014...

BACKGROUND: Metabolic acidosis frequently is present in surgical patients; however, different types of metabolic acidosis (hyperlactatemia, hyperchloremia, and others) may have different relationships to perioperative outcomes. We hypothesized that in postoperative surgical patients, distinctive types of metabolic acidosis would correlate differently with the outcomes of high-risk surgeries. METHODS: A prospective, multicenter observational study was performed in 3 different tertiary care hospitals...

The mitochondrial inner membrane possesses distinct subdomains including cristae, which are lamellar structures invaginated into the mitochondrial matrix and contain the respiratory complexes. Generation of inner membrane domains requires the complex interplay between the respiratory complexes, mitochondrial lipids and the recently identified mitochondrial contact site and cristae organizing system (MICOS) complex. Proper organization of the mitochondrial inner membrane has recently been shown to be important for respiratory function in yeast...

BACKGROUND: Septic shock has a 90-day mortality risk of up to 50 %. The hemodynamic targets, including mean arterial pressure (MAP) are not based on robust clinical data. Both severe hypotension and high doses of vasopressors may be harmful. Hence, re-evaluation of hemodynamic targets in septic shock is relevant. METHODS/DESIGN: The targeted tissue perfusion versus macrocirculation-guided standard care in patients with septic shock (TARTARE-2S) trial is a prospective, two-parallel-group, randomized, open-label, multicenter trial with assessor-blinded outcome evaluation...

BACKGROUND: Persistent hyperlactatemia during septic shock is multifactorial. Hypoperfusion-related anaerobic production and adrenergic-driven aerobic generation together with impaired lactate clearance have been implicated. An excessive adrenergic response could contribute to persistent hyperlactatemia and adrenergic modulation might be beneficial. We assessed the effects of dexmedetomidine and esmolol on hemodynamics, lactate generation, and exogenous lactate clearance during endotoxin-induced septic shock...

Lactic acid (2-Hydroxypropanoic acid) is generated from pyruvic acid under anaerobic condition in skeletal muscles, brain, red blood cells, and kidney. Lactate in normal human subjects get cleared very quickly at a rate of 320mmol/L/hr, mostly by liver metabolism and re-conversion of lactate back to pyruvate. Measurement of lactate level in serum is required for the differential diagnosis and medical management of hyperlactatemia, cardiac arrest and resuscitation, sepsis, reduced renal excretion, hypoxia induced cancer, decreased extra hepatic metabolism, intestinal infarction and lactic acidosis...

BACKGROUND: Hundreds of thousands of craniotomies are performed annually in the United States. During craniotomy, elevated serum lactate is a concerning and not infrequent occurrence. Elevated intraoperative serum lactate may occur as a result of global hypoperfusion or localized intracerebral ischemia from surgical retraction or inadequate blood supply. The distinction between systemic and hypoperfusion confined to the brain is important because the treatment differs. For example, fluid resuscitation may be indicated in the former but not the latter...

BACKGROUND: The cecal ligation and puncture (CLP) model, a gold standard in sepsis research, is associated with an important variability in mortality. While the number of punctures and needle size is well described in CLP animal studies, the length of cecal ligation is often not. The relationship between cecal ligation and survival in mice is briefly reported in the literature; therefore, we devised an investigation in mice of the consequences of three standardized cecal ligation lengths on mortality and the severity of the ensued sepsis...

INTRODUCTION: There is no comprehensive data or studies relating to clinical presentation and prognosis of cerebral malaria (CM) in the tribal settlements of Assam. High rates of transmission and deaths from complicated malaria guided us to conduct a prospective observational cohort study to evaluate the factors associated with poor outcome and prognosis in patients of CM. MATERIALS AND METHODS: We admitted 112 patients to the Bandarpara and Damodarpur Tribal Health Centers (THCs) between 2011 and 2013 with a strict diagnosis of CM...

OBJECTIVE: Hyperlactatemia and base deficit (BD) are markers of adverse outcome after cardiac surgery, and their derangement can be influenced by the use of extracorporeal circulation. The authors hypothesized a better postoperative metabolic profile in off-pump coronary artery bypass grafting (OPCABG) compared with "on-pump" coronary artery bypass grafting (ONCABG). DESIGN: This was a retrospective study, with consecutive data collected for 1 year from electronic medical records...
