BACKGROUND: Obesity is often associated with nonalcoholic fatty liver disease (NAFLD), which refers to a large spectrum of hepatic lesions including fatty liver, nonalcoholic steatohepatitis (NASH) and cirrhosis. Different investigations showed or suggested that obesity and NAFLD are able to increase the risk of hepatotoxicity of different drugs. Some of these drugs could induce more frequently an acute hepatitis in obese individuals whereas others could worsen pre-existing NAFLD. AIM: The main objective of the present review was to collect the available information regarding the role of NAFLD as risk factor for drug-induced hepatotoxicity...

Drug-induced liver injury (DILI) is a common reason for withdrawal of candidate drugs from clinical trials, or of approved drugs from the market. DILI may be induced not only by intact parental drugs, but also by metabolites or intermediates, and therefore should be evaluated in the enzyme-induced state. Here, we present a protocol for assay of drug-metabolizing enzyme-inducing potential using three-dimensional (3D) primary cultures of human hepatocytes (hepatocyte spheroids). Hepatocyte spheroids could be used up to 21 d after seeding (pre-culture for 7 d and exposure to inducer for up to 14 d), based on preliminary evaluation of basal activities of CYP subtypes and mRNA expression of the corresponding transcription factor and xenobiotic receptors (aryl hydrocarbon receptor (AhR), constitutive androstane receptor (CAR) and pregnane X receptor (PXR))...

Drug reaction with eosinophilia and systemic symptom (DRESS) is a serious idiosyncratic drug reaction. It is characterized by skin eruption, fever, hematologic abnormalities, and multi-organ involvement. Diagnosis is challenging because of the wide clinical spectrum. Its association with aromatic antiepileptic drugs, such as phenytoin, phenobarbital, and carbamazepine, has been well described in adults. There are few reports of DRESS syndrome in children, and knowledge about the relationship between new antiepileptic drugs such as oxcarbazepine and this syndrome is limited...

A two-year-old female spayed domestic shorthair cat was presented with apathy, inappetence and generalised lymphadenomegaly. Anamnestic data included a generalised seizure disorder and phenobarbital treatment started one month before presentation. Routine blood analysis revealed only mild abnormalities and FeLV and FIV tests were negative. Both popliteal lymph nodes were aspirated and cytology was consistent with reactive lymph node hyperplasia. PCR for antigen receptor rearrangement testing diagnosed a polyclonal cell population...

Octamethylcyclotetrasiloxane (D4) is a volatile cyclic siloxane used primarily as a monomer or intermediate in the production of some silicon-based polymers widely used in industrial and consumer applications and may be present as a residual impurity in a variety of consumer products. A robust toxicological data set exists for D4. Treatment-related results from a chronic inhalation study conducted in rats are limited to mild effects on the respiratory tract, increases in liver weight, increases in the incidence of uterine endometrial epithelial hyperplasia, and a dose-related trend in the incidence of endometrial adenomas...

Phenobarbital is the most commonly used drug for the treatment of neonatal seizures but may induce neurodegeneration in the developing brain. Methylxanthine caffeine is used for the treatment of apnea in newborn infants and appears to be neuroprotective, as shown by antiapoptotic and anti-inflammatory effects in oxidative stress models in newborn rodents and reduced rates of cerebral palsy in human infants treated with caffeine. We hypothesized that caffeine may counteract the proapoptotic effects of phenobarbital in newborn rats...

A genome-wide ENU mutagenesis screen in mice was performed to identify novel regulators of erythropoiesis. Here we describe a mouse line, RBC16, which harbours a dominantly inherited mutation in the Cpox gene, responsible for production of the haem biosynthesis enzyme, coproporphyrinogen III oxidase (CPOX). A premature stop codon in place of a tryptophan at amino acid 373 results in reduced mRNA expression and diminished protein levels, yielding a microcytic red cell phenotype in heterozygous mice. Urinary and faecal porphyrins in female RBC16 heterozygotes were significantly elevated compared to that of wildtype littermates, particularly coproporphyrinogen III, while males were biochemically normal...

BACKGROUND: Neonatal seizures are the most common clinical manifestation of central nervous system (CNS) dysfunction and are associated with various neurological sequelae. There are currently no evidence-based guidelines for the management of neonatal seizures and currently used drugs such as phenobarbital, and phenytoin have limited efficacy and potential toxicities. Newer second line anticonvulsant, levetiracetam, has been used in refractory neonatal seizures despite limited data and off-label use...

Crigler-Najjar syndrome is a hereditary unconjugated hyperbilirubinemia. Two forms of the disease are recognized. Type I is more severe and results in kernicterus if left untreated, and Type II is less severe and responds to phenobarbital. While Crigler-Najjar syndrome is thought by many to have normal liver histology, few reports of the liver pathology exist. Herein, we present a 19-year-old patient with Crigler-Najjar who underwent liver transplantation. The liver showed marked canalicular cholestasis with portal and variable, delicate, bridging fibrosis...

Research studies suggest that neonatal seizures, which are most commonly associated with hypoxic-ischemic injury, may contribute to brain injury and adverse neurologic outcome. Unfortunately, neonatal seizures are often resistant to treatment with current anticonvulsants. In the present study, we evaluated the efficacy of flupirtine, administered at clinically relevant time-points, for the treatment of neonatal seizures in an animal model of hypoxic-ischemic injury that closely replicates features of the human syndrome...

BACKGROUND: Progressive liver fibrosis leads to cirrhosis and end-stage liver disease. This disease is a consequence of strong interactions between matrix-producing hepatic stellate cells (HSCs) and resident and infiltrating immune cell populations. Accumulated experimental evidence supports the involvement of adult-derived human liver mesenchymal stem/progenitor cells (ADHLSCs) in liver regeneration. The aim of the present study was to evaluate the influence of ADHLSCs on HSCs, both in vitro and in vivo...
