Article Synopsis
  • - Non-alcoholic fatty liver disease (NAFLD) includes various liver conditions like steatosis and can lead to serious issues, but its impact on drug metabolism, specifically via cytochrome P450 enzymes, is not well understood.
  • - Researchers used a methionine-choline deficient diet to induce NAFLD in study subjects and employed advanced methods to analyze over 1,200 hepatic proteins, finding significant changes in their levels.
  • - The study revealed that many cytochrome P450 enzymes were down-regulated in NAFLD, affecting drug metabolism, but CYP2D levels remained stable, highlighting the complex interactions between liver health and drug processing.

Aluminum phosphide (AlP) poisoning is a severe toxicity with 30-70% mortality rate. However, several case reports presented AlP-poisoned patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency and extensive hemolysis who survived the toxicity. This brought to our mind that maybe G6PD deficiency could protect the patients from severe fatal poisoning by this pesticide.

Toxicological Research Center, Department of Clinical Toxicology, Loghman-Hakim Hospital, School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Endoscopy is generally speculated to be unnecessary in sodium hypochlorite (NaClO) ingestions; however, a significant number of endoscopic evaluations are still being performed when this chemical is ingested. Therefore, the aim of the current study was to compare the outcome and endoscopic findings between patients who had ingested household NaClO and those who had ingested other types of corrosives. This retrospective cohort study enrolled 137 patients with a history of corrosive substance ingestion admitted to a tertiary hospital.

High mortality rates have been reported for methadone in both adults and children. We aimed to determine the pattern of toxicity, possible underlying diseases and treatment challenges in patients referred to our centre with early diagnosis of methadone toxicity and who later died. Medical files of all methadone-poisoned patients who had been admitted to a referral centre of toxicology between March 2011 and March 2016, died during the hospital stay and sent for autopsy to Legal Medicine Organization were retrospectively evaluated.

Potential Role of Patients' CYP3A-Status in Clozapine Pharmacokinetics.

Int J Neuropsychopharmacol

July 2017

Research Centre for Natural Sciences, Hungarian Academy of Sciences, Budapest Hungary; Department of Psychiatry and Psychotherapy, Semmelweis University, Budapest Hungary; Toxi-Coop Toxicological Research Center, Budapest Hungary; University of Ljubljana, Ljubljana Slovenia.

Background: The atypical antipsychotic clozapine is effective in treatment-resistant schizophrenia; however, the success or failure of clozapine therapy is substantially affected by the variables that impact the clozapine blood concentration. Thus, elucidating the inter-individual differences in clozapine pharmacokinetics can facilitate the personalized therapy.

Methods: Since a potential role in clozapine metabolism is assigned to CYP1A2, CYP2C19, CYP2D6 and CYP3A enzymes, the association between the patients' CYP status (CYP genotypes, CYP expression) and clozapine clearance was evaluated in 92 psychiatric patients.

Article Synopsis
  • Naloxone is commonly used to treat opioid-dependent patients experiencing respiratory depression, but it can cause serious complications in these individuals.
  • Using buprenorphine, a partial μ-opioid receptor agonist, could be a safer option for reversing respiratory depression while minimizing severe withdrawal symptoms.
  • A case study of a 20-year-old man with morphine addiction demonstrated that intravenous buprenorphine effectively addressed respiratory depression induced by methadone.

Poisoning with tricyclic antidepressants is an important cause of drug-related self-poisoning in the developed world and a very common cause of poisoning and mortality in developing countries. Electrocardiographic manifestations of most tricyclic antidepressant-poisoned patients resolve by the administration of 1-2 mEq/kg of sodium bicarbonate. Some rare cases have been reported who have been resistant to the long-term or high doses of bicarbonate administration.

Saccharin, the first artificial sweetener, was discovered in 1879 that do not have any calories and is approximately 200~700 times sweeter than sugar. Saccharin was the most common domestically produced sweetener in Korea in 2010, and it has been used as an alternative to sugar in many products. The interaction between artificial sweeteners and drugs may affect the drug metabolism in patients with diabetes, cancer, and liver damage, this interaction has not been clarified thus far.
