OBJECTIVE: To determine the prevalence of alteration in liver functions tests and associated factors for severity among Peruvian COVID-19 patients. MATERIALS AND METHODS: A descriptive, retrospective and cross-sectional study was performed in 4 public hospitals in Peru...

BACKGROUND: Infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may not elicit lifelong protective immunity and reinfection could occur. Liver function impairment is a common manifestation of coronavirus disease 2019 (COVID-19). However, acute hepatic failure in the setting of COVID-19 is very rare. CASE PRESENTATION: We report the case of a 47-year-old woman who presented with acute abdominal pain and vomiting. Abdominal examination revealed a soft and lax abdomen with mild tenderness in the right upper quadrant...

WHAT IS KNOWN AND OBJECTIVES: Acetaminophen has been increasingly used in treating patent ductus arteriosus (PDA) in preterm neonates. Variations were observed in the dosing regimen of acetaminophen across the studies. There is hardly any data available for a relatively higher dose of intravenous acetaminophen (15 mg/kg/dose every 6 hours) in the preterm population. We present here the results of a prospective study with this dose of intravenous acetaminophen for treating PDA in critically ill preterm neonates...

Aim of this study to evaluate the safety profile, hepatoprotective and in-vivo antioxidant activities of Dicliptera bupleuroides Nees. Toxicity studies were conducted in human RBCs and DNA by using standard procedures. Acute hepatoprotective investigation was carried out in albino rats by treated with all six fractions of D. bupleuroides 350 mg/kg/day. ALT, AST, ALP and total bilirubin (TB) were performed. The n-hexane fraction (200 mg/kg/day) exhibited appropriate hepatoprotective activity hence subjected to chronic study (14 days)...

Neck of femur fracture is a common consequence of falls in the elderly with a large burden of morbidity and mortality. Derangement in liver function tests (LFTs) is frequently seen in elderly people with neck of femur (NOF) fracture in the peri-operative period and can indicate serious and treatable underlying pathology as well as prognosis.On admission, raised alkaline phosphatase (ALP) levels with normal gamma-glutamyl transferase (GGT) suggest underlying bone pathology such as osteomalacia or Paget's disease but do not confirm or exclude osteoporosis...

Acetaminophen has a remarkable safety profile when prescribed in proper therapeutic doses, but hepatotoxicity can occur when misused or after an overdose. The principal toxic metabolite of acetaminophen is N-acetyl-p-benzoquinone imine (NAPQI). Toxicity should be considered in all suspicious cases because of the ubiquitous and initially asymptomatic nature of acetaminophen intoxication. A case of 29-year male soldier is discussed, who presented with pain in abdomen, vomiting and jaundice of sudden onset. The diagnosis of ischemic liver damage was made at initial presentation...

Background: Probiotics have attracted a great attention aiming to develop natural non-toxic antioxidants, because of their role in decreasing the risk of reactive oxygen species [ROS] accumulation. Objectives: The purpose of this study was to assess the antioxidant activity of a probiotic Streptococcus salivarius ssp thermophillus [St.sa] and to evaluate its protective effect against the oxidative stress induced by a toxic dose of paracetamol in Wistar rats. Materials and Methods: Several assays were used to investigate the in vitro antioxidant capacity of the strain...

INTRODUCTION: In this prospective study, we compared the efficacy and safety of ibuprofen, indomethacin, and paracetamol in the closure of patent ductus arteriosus (PDA) in preterm neonates. MATERIALS AND METHODS: This randomized prospective study was conducted in the Division of Pediatric Cardiology, M. D. M and Umaid Hospital, Jodhpur. A total of 105 preterm neonates with gestational age <37 weeks and hemodynamically significant PDA (hs-PDA) diagnosed clinically and confirmed by echocardiography were enrolled...

​Serum concentrations of paracetamol are measured to investigate the cause of acute hepatitis, monitor the clearance of paracetamol from the body and to determine if supratherapeutic levels warrant treatment with N-acetylcysteine (NAC). ​A 49-year-old man treated for ischaemic colitis developed worsening renal and liver function tests. As part of the investigation of hepatorenal failure, paracetamol levels were requested, which were elevated at 14 mg/L (normal <4 mg/L) resulting in treatment with NAC...

BACKGROUND: Despite the emergence of cell-free DNA (cfDNA) as a clinical biomarker in cancer, the tissue origins of cfDNA in healthy individuals have to date been inferred only by indirect and relative measurement methods, such as tissue-specific methylation and nucleosomal profiling. METHODS: We performed the first direct, absolute measurement of the tissue origins of cfDNA, using tissue-specific knockout mouse strains, in both healthy mice and following paracetamol (APAP) overdose...

Paracetamol, chemically known as acetaminophen, if taken in higher doses has hepatotoxic potential. Cimetidine by inhibiting the cytochromal enzymes and reducing the production of the toxic metabolite can reduce the hepatotoxic potential while Verapamil can act as a hepatoprotective by maintaining calcium homeostasis. The present study was conducted to study the hepatoprotective activity of Cimetidine and Verapamil against the toxicity induced by paracetamol. In addition to the group receiving only distilled water or 300 mg/kg paracetamol additional groups were added treated with 150 mg/kg Cimetidine and Verapamil alone or both...

BACKGROUND: In veterinary medicine, the administration of nonsteroidal anti-inflammatory analgesics (NSAIDs) for the control of postsurgical pain in dogs and cats is common given the anti-inflammatory, analgesic, and antipyretic effects of these drugs. This study compared the serum biochemical changes and postoperative analgesic effects of paracetamol, meloxicam, and carprofen in bitches submitted to an ovariohysterectomy using the Dynamic Interactive Visual Analog Scale (DIVAS) and Pain Scale of the University of Melbourne (UMPS) scoring systems...

ETHNOPHARMACOLOGICAL RELEVANCE: The liver and kidney are among the most important organs in the body, where metabolic and elimination functions take place. During this process, liver and kidneys may suffer damage due to ingestion or formation of toxic metabolites leading to organ loss and even death. Artichoke (Cynara scolymus L.) leaf has long been recognized as a popular herbal remedy in traditional medicines with beneficial effects on liver. AIM OF THE STUDY: In phytotherapy leaves are the part used to support the liver functions and for treatment of damage induced by various toxins, while fleshy receptacle is cooked as meal to support liver homeostasis...

A mathematical model has been developed to assist with the development of a hollow fibre bioreactor (HFB) for hepatotoxicity testing of xenobiotics; specifically, to inform the HFB operating set-up, interpret data from HFB outputs and aid in optimizing HFB design to mimic certain hepatic physiological conditions. Additionally, the mathematical model has been used to identify the key HFB and compound parameters that will affect xenobiotic clearance. The analysis of this model has produced novel results that allow the operating set-up to be calculated, and predictions of compound clearance to be generated...

The present work aimed to prepare silymarin-loaded mesoporous silica nanoparticles (MSNs) and to assess the system's dissolution enhancement ability on the pharmacodynamic performance of silymarin as a hepatoprotective agent. For this purpose, a soft-templating technique was used to prepare silymarin-loaded MSNs. The loaded MSNs were further characterized for their particle size, zeta potential, surface properties, and in vitro drug dissolution testing. In addition, differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) were also carried out...

BACKGROUND: Paracetamol (acetaminophen) is vastly recommended as the first-line analgesic for osteoarthritis of the hip or knee. However, there has been controversy about this recommendation given recent studies have revealed small effects of paracetamol when compared with placebo. Nonetheless, past studies have not systematically reviewed and appraised the literature to investigate the effects of this drug on specific osteoarthritis sites, that is, hip or knee, or on the dose used. OBJECTIVES: To assess the benefits and harms of paracetamol compared with placebo in the treatment of osteoarthritis of the hip or knee...

Paracetamol (N-acetyl-para amino phenol) is the most commonly used analgesic and antipyretic around the world. Its causes hepatotoxicity and nephrotoxicity at overdose or even at therapeutic doses. It is primarily metabolized by glucuronidation and sulfate conjugation. It is also metabolized by cytochrome-P450 system (CYP2E1, CYP1A2 and CYP 3A4), leading to the formation of N-acetyl-p-benzoquinoneimine (NAPQI). The present study was planned to investigate the influence of chrysin (known CYP2E1 and CYP3A4 inhibitor) on the bioactivation of paracetamol to NAPQI using rat liver microsomes in vitro and rats in vivo...

Medicinal plants over time have proven to have potential to manage a huge number of diseases and disorders and thus have become a great source of pharmaceutical drugs. One of such plants is Tapinanthus bangwensis (African mistletoe). It is a semiparasitic and epiphytic plant growing on citrus tree, obtaining its food photosynthetically while its nutrient and water is got from the host plant. The aim of this study was to determine the cytotoxicological and hepatocurative effect of aqueous fraction of T bangwensis in acetaminophen (paracetamol)-induced Wistar rats...

The current studies were sought to determine effects of antioxidant potential of aqueous and methanolic extracts of Phoenix dactylifera leaves (PLAE and PLME) against the widely-used analgesic paracetamol (PCM) induced hepatotoxicity. Groups of rats were treated with or without PCM (1500 mg/kg), PLAE and PLME (300 mg/kg) and n-acetylcysteine (NAC, 50 mg/kg) followed by assessments of liver function tests, oxidative stress, antioxidant defenses, and hepatotoxicity. We observed that PCM significantly elevated serum liver markers, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), and bilirubin compared to control (untreated) group...
