This study was aimed at determining the efficacy of epinephrine, followed by chest compressions, in producing a return of spontaneous circulation (ROSC) during cyanide (CN)- or hydrogen sulfide (H2 S)-induced toxic cardiac pulseless electrical activity (PEA) in the rat. Thirty-nine anesthetized rats were exposed to either intravenous KCN (n = 27) or H2 S solutions (n = 12), at a rate that led to a PEA within less than 10 min. In the group intoxicated by CN, 20 rats were mechanically ventilated and received either epinephrine (0...

BACKGROUND: Current treatment options for chronic hepatitis B (CHB) are pegylated interferon alpha and nucleoside analogues (NAs). NAs have relatively fewer side effects than interferon alpha, and generally well tolerated. Previously 12.9% of patients on telbivudine treatment were reported to develop severe elevation of serum creatine phosphokinase (CPK) levels, but related clinical disease, like lactic acidosis (LA) and rhabdomyolysis (RM) were rare. The pathophysiology may be mitochondrial toxicity, for the NAs inhibit not only hepatitis B virus (HBV) polymerase, but also the host mitochondrial DNA polymerase γ...

AIM: Extensive on-going research on probiotics and infant formulas raises a number of safety questions. One concern is the potential influence of D-lactic acid-containing preparations on the health of infants and children. The aim of this review was to summarise the available knowledge on the ingestion of D-lactic acid-producing bacteria, acidified infant formulas and fermented infant formulas as a potential cause of paediatric D-lactic acidosis. METHODS: A Medline database search was performed in July 2017, with no restrictions on the language, article type or publication date...

Suvi T Vaara, Rinaldo Bellomo
Continuous renal replacement therapy (CRRT) has many potential indications that extend beyond the traditional removal of uremic waste products. Many of these stem from the capacity of CRRT to remove middle-sized molecules and its suitability for haemodynamically unstable patients. Using CRRT for immunomodulation to remove circulating plasma cytokines has created great enthusiasm and, in the past, immunomodulation was a frequently reported indication for commencing CRRT. Unfortunately, recent evidence from randomized controlled trials has been discouraging, and CRRT cannot be recommended for immunomodulation...

The mitochondrial cytopathies are a heterogeneous group of diseases characterized by heteroplasmic maternal transmission and selective dysfunction of tissues and organs highly dependent on aerobic respiration (eg, skeletal muscle, cardiac muscle, and brain). Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) is a specific subtype of mitochondrial cytopathy that is commonly associated with mood disturbances in individuals who survive until adulthood. Because of the altered cellular metabolism inherent in MELAS, it is often difficult to determine drug dosing, drug choice, and treatment response in patients with this rare disease...

We report an aggressive case of polymicrobial bacteremia in a patient with renal pelvis carcinoma. A 76-year-old man developed watery diarrhea after undergoing chemotherapy. He became unconscious and went into shock. Laboratory data showed severe neutropenia, renal failure, and lactic acidosis. Chest radiography showed multiple opacities. He died despite aggressive fluid resuscitation, catecholamine administration, antibiotic treatment, and mechanical ventilation. Blood culture isolates included Escherichia coli , Klebsiella pneumoniae , Streptococcus pneumoniae , Acinetobacter baumannii , and Moraxella catarrhalis ...

We report the prenatal findings of severe cerebellar growth arrest in two siblings with POLG1 mutations. The first presented with seizures and lactic acidosis immediately after premature birth and was diagnosed with mitochondrial disease on muscle biopsy. Molecular DNA analysis confirmed homozygous missense mutation in the POLG1 gene. The pregnancy of the second sibling was monitored closely by repeat fetal ultrasounds since the parents declined invasive testing. A detailed fetal ultrasound at 19 weeks gestation showed a small cerebellum with transcerebellar diameter (TCD) on axial cranial imaging, measuring below the 5th centile for gestational age...

Due to a lack of reference values for blood concentration of metformin in the literature, the forensic evaluation of metformin findings in blood samples is difficult. Interpretations with regard to the assessment of blood concentrations as well as an estimation of the ingested metformin amounts are often vague. Furthermore, post mortem evaluation of death due to lactic acidosis because of metformin is difficult since renal performance or lactate concentrations can not always reliably be determined after death...

Short bowel syndrome (SBS) can lead to many complications related to the condition and its therapy. We describe 2 children with SBS who we believe are the second and third patients documented to have experienced both D-lactic acidosis and urolithiasis. We review aspects of these SBS complications and recent findings on the microbiome of patients with SBS that may predispose to these complications.

Primary CoQ10 deficiency is a clinically and genetically heterogeneous, autosomal recessive disorder resulting from mutations in genes involved in the synthesis of coenzyme Q10 (CoQ10 ). To date, mutations in nine proteins required for the biosynthesis of CoQ10 cause CoQ10 deficiency with varying clinical presentations. In 2009 the first patient with mutations in COQ9 was reported in an infant with a neonatal-onset, primary CoQ10 deficiency with multi-system disease. Here we describe four siblings with a previously undiagnosed lethal disorder characterized by oligohydramnios and intrauterine growth restriction, variable cardiomyopathy, anemia, and renal anomalies...

It is conservatively estimated that 5,000 deaths per year and 20,000 injuries in the USA are due to poisonings caused by chemical exposures (e.g., carbon monoxide, cyanide, hydrogen sulfide, phosphides) that are cellular inhibitors. These chemical agents result in mitochondrial inhibition resulting in cardiac arrest and/or shock. These cellular inhibitors have multi-organ effects, but cardiovascular collapse is the primary cause of death marked by hypotension, lactic acidosis, and cardiac arrest. The mitochondria play a central role in cellular metabolism where oxygen consumption through the electron transport system is tightly coupled to ATP production and regulated by metabolic demands...

Triumeq is a single-tablet regimen for patients with HIV infection comprising dolutegravir, abacavir and lamivudine. Overdoses with Triumeq have not been reported previously. We present a case of a 26-year-old man who presented to our hospital after intentionally ingesting 30 tablets of Triumeq. An intoxication with Triumeq can lead to several side effects. An overdose of abacavir and lamivudine can cause mitochondrial toxicity and lactic acidosis. An intoxication with dolutegravir appears to be relatively harmless...

Combination antiretroviral drug treatments depend on 3'-deoxy-nucleoside analogs such as AZT (3'-azido-3'-deoxythymidine) and DDI (2'3'-dideoxyinosine). Despite being effective in inhibiting HIV viral replication, these drugs produce a range of toxicities, including myopathy, pancreatitis, neuropathy and lactic acidosis, that are generally considered as sequelae to mitochondrial damage. While the cell surface localized nucleoside transporters (e.g., human equilibrative nucleoside transporter 2 (hENT2), human concentrative nucleoside transporter 1 (hCNT1)) are known to increase the carrier mediated uptake of 3'-deoxy-nucleoside analogs into cells, another ubiquitously expressed intracellular nucleoside transporter, namely, hENT3, has been implicated in the mitochondrial transport of 3'-deoxy-nucleoside analogs...
