AIM: Acute-onset autoimmune hepatitis (AIH) histopathologically presents with features of acute hepatitis and lacks a specific diagnostic method. Also, AIH is often difficult to differentiate from drug-induced liver injury (DILI). We aimed to investigate the final clinical diagnosis of these cases, and compare the clinical, biochemical, and histological characteristics of AIH vs. DILI. METHODS: We examined the Digestive Disease Week Japan 2004 (DDW-J) scale scores, AIH scores, clinical data, and pathological findings in 20 patients in whom it was difficult to differentiate autoimmune liver disease from DILI...

BACKGROUND: Personalized immunosuppressive therapy, including accurate drug dosing based on drug blood level, leads to better clinical outcomes, specifically with regard to avoidance of drug-induced adverse effects and maintenance of efficacy. Mycophenolic acid (MPA) is used as an immunosuppressant in transplantation of various solid organs. The aim of this study was to develop a method for quantification of MPA and its metabolites, mycophenolic acid 7-O-glucuronide (MPAG) and mycophenolic acid acyl glucuronide, in dried blood spot (DBS) samples, using liquid chromatography/electrospray ionization/tandem mass spectrometry...

Aims: Patients with the Brugada type 1 ECG (Br type 1) without previous aborted sudden death (aSD) who do not have a prophylactic ICD constitute a very large population whose outcome is little known. The objective of this study was to evaluate the risk of SD or aborted SD (aSD) in these patients. Methods and results: We conducted a meta-analysis and cumulative analysis of seven large prospective studies involving 1568 patients who had not received a prophylactic ICD in primary prevention...

Intrinsic tooth discoloration may occur as an adverse effect of fluoride and tetracyclines. Extrinsic tooth discoloration may occur as superficial staining or as discoloration of the superficial pellicle and/or biofilm due to chlorhexidine, liquid iron salts, essential oils, some antibiotics and stannous fluoride. Inhibition of orthodontic tooth movement has been reported due to the use of prostaglandin synthetase inhibitors. If medications or over-the-counter drugs induce hyposalivation or contain much sucrose, caries may develop...

BACKGROUND AND AIMS: Isoniazid (INH) is part of the first-line-therapy for tuberculosis (TB) but can cause drug-induced liver injury (DILI). Several candidate single nucleotide polymorphisms (SNPs) have been previously identified but the clinical utility of these SNPs in the prediction of INH-DILI remains uncertain. The aim of this study was to assess the association between selected candidate SNPs and the risk of INH-DILI and to assess the clinical validity of associated variants in a Singaporean population...

BACKGROUND/AIMS: Acetaminophen (APAP) refers to a medication used to manage pain and fever symptoms. Heat shock protein 90 (Hsp90) is to be expressed during various stresses, such as wound healing and tissue remodeling. Recently, it is discovered that Hsp90 is a potential modifier of cytogenesis. In comparison to clinical references of liver damage, this study was designed to assess the potential bioeffect of Hsp90 in APAP-treated livers without conspicuous drug induced liver injury (DILI)...

Afterglow optical agents, which emit light long after cessation of excitation, hold promise for ultrasensitive in vivo imaging because they eliminate tissue autofluorescence. However, afterglow imaging has been limited by its reliance on inorganic nanoparticles with relatively low brightness and short-near-infrared (NIR) emission. Here we present semiconducting polymer nanoparticles (SPNs) <40 nm in diameter that store photon energy via chemical defects and emit long-NIR afterglow luminescence at 780 nm with a half-life of ∼6 min...

REVIEW
Roberta Angelico, Alessandro Parente, Tommaso Maria Manzia
Hepatocellular carcinoma (HCC) recurrence rate after liver transplantation (LT) is still up to 15-20%, despite a careful selection of candidates and optimization of the management within the waiting list. To reduce tumour recurrence, the currently adopted post-transplant strategies are based on the administration of a tailored immunosuppression (IS) regimen. Drug-induced depression of the immune system is essential in preventing graft rejection, however has a well-established association with oncogenesis. The immune system has a key role as a defending mechanism against cancer development, preventing vascular invasion and metastasis...

Nafcillin-induced acute liver injury is a rare and potentially fatal complication that has been known since the 1960s but inadequately studied. At this time, the only proven treatment is early discontinuation of the drug. Because of the high prevalence of nafcillin class antibiotic use in the United States, it is important for clinicians to have a high clinical suspicion for this diagnosis. We present a case of liver failure attributable to nafcillin use in a 68-year-old male with a history methicillin-sensitive Staphylococcus and L3/L4 osteomyelitis...

Adverse drug reactions are among the most frequent side effects of synthetic and complementary alternative drugs and represent the premier causes of license revocations and acute liver failure. Drug-induced liver injury can resemble literally any other genuine liver disease and usually responds well to drug dechallenge. However, in some cases autoimmune-like hepatitis can evolve, requiring short- and sometimes long-term immunosuppression. Here, we present the hitherto first case of autoimmune-like hepatitis following treatment with zoledronic acid...

Gingival overgrowth (GO) is one of the common findings in clinical practice. There could be several causes including drugs associated with the GO. Carbamazepine (CBZ) and amlodipine are the drugs which are infrequently documented as a cause in inducing the gingival hyperplasia. Certain drugs in the body fluid might limit the population of plaque bacteria and alter their metabolism that in turn induce the inflammatory mediators and also activate the genetic and biochemical factors responsible for gingival fibroblast growth...

Idiosyncratic drug-induced liver injury (DILI) is damage to liver occurring at recommended dose of a drug in contrast to toxic or predictable DILI. Although it is common in first-generation antiepileptic drugs (AEDs), it is rare in newer AEDs such as topiramate. Topiramate commonly causes neurological adverse effects such as psychomotor slowing and somnolence. Hepatotoxicity by topiramate is rare and has been previously reported in combination with other drugs such as valproate and carbamazepine. Here, we report a case of topiramate-induced asymptomatic elevation of liver enzymes in an adult man diagnosed with alcohol dependence syndrome and alcohol withdrawal complicated with seizures...

Antagonists of MDM2-p53 interaction are emerging anti-cancer drugs utilized in clinical trials for malignancies that rarely mutate p53, including melanoma. We discovered that MDM2-p53 antagonists protect DNA from drug-induced damage in melanoma cells and patient-derived xenografts. Among the tested DNA damaging drugs were various inhibitors of Aurora and Polo-like mitotic kinases, as well as traditional chemotherapy. Mitotic kinase inhibition causes mitotic slippage, DNA re-replication, and polyploidy. Here we show that re-replication of the polyploid genome generates replicative stress which leads to DNA damage...

The use of amphetamine-type stimulants (ATS) and ketamine is of particular clinical concern because of its associated psychotic symptoms. In Chinese clinical practice, ATS and ketamine are commonly used simultaneously, but very few studies have reported the symptom profile of users who use both drugs. This study determined whether the combined use of ATS and ketamine is associated with more psychotic symptoms than either ATS or ketamine alone. According to drug use characteristics, 375 Chinese synthetic drug users were categorized into 2 pairs of comparison groups: ATS-only (n=125) vs...
