Spectrum of drug-induced liver injury in a tertiary hospital in southern India.

Background Anti-tuberculosis drugs are thought to account for about 50% of drugs that cause liver injury in India. We show that the spectrum of drugs is much wider than previously reported. Methods We evaluated all patients with unexplained acute liver injury presenting during 2006-2016 using a structured proforma for drug-induced liver injury (DILI).

Functional Outcome of Joshi's External Stabilization System Fixation in Distal Radius Fractures.

Background Distal radius fractures account for almost one-sixth of all fractures in a casualty setting. The usual aim of distal radius fracture treatment is to restore the function of the wrist joint, of which the distal radius is an important part. There seems to be no consensus regarding which mode of treatment is optimal for managing distal radius fracture, particularly when it is associated with distal radioulnar joint instability.

A Semimechanistic Pharmacokinetic Model for Depot Medroxyprogesterone Acetate and Drug-Drug Interactions With Antiretroviral and Antituberculosis Treatment.

Depot medroxyprogesterone acetate is an injectable hormonal contraceptive, widely used by women of childbearing potential living with HIV and/or tuberculosis. As medroxyprogesterone acetate is a cytochrome P450 (CYP3A4) substrate, drug-drug interactions (DDIs) with antiretroviral or antituberculosis treatment may lead to subtherapeutic medroxyprogesterone acetate concentrations (< 0.1 ng/mL), resulting in contraception failure, when depot medroxyprogesterone is dosed at 12-week intervals.

Phase separation of an active colloidal suspension via quorum-sensing.

We present the Brownian dynamics simulation of an active colloidal suspension in two dimensions, where the self-propulsion speed of a colloid is regulated according to the local density sensed by it. The role of concentration-dependent motility in the phase-separation of colloids and their dynamics is investigated in detail. Interestingly, the system phase separates at a very low packing fraction (Φ≈ 0.

Hemochromatosis in India: First Report of Whole Exome Sequencing With Review of the Literature.

Background: Primary hemochromatosis is unusual in India. The homeostatic iron regulator (HFE) gene C282Y mutation, a common cause for hemochromatosis in Europe, is considered almost nonexistent in India. We are reporting a case of hemochromatosis with the HFE gene C282Y mutation and two other adult cases with a novel hemojuvelin (HJV) mutation from Kerala.

An Individual Participant Data Population Pharmacokinetic Meta-analysis of Drug-Drug Interactions between Lumefantrine and Commonly Used Antiretroviral Treatment.

Treating malaria in HIV-coinfected individuals should consider potential drug-drug interactions. Artemether-lumefantrine is the most widely recommended treatment for uncomplicated malaria globally. Lumefantrine is metabolized by CYP3A4, an enzyme that commonly used antiretrovirals often induce or inhibit.

A Population Pharmacokinetic Analysis Shows that Arylacetamide Deacetylase (AADAC) Gene Polymorphism and HIV Infection Affect the Exposure of Rifapentine.

Rifapentine is a rifamycin used to treat tuberculosis. As is the case for rifampin, plasma exposures of rifapentine are associated with the treatment response. While concomitant food intake and HIV infection explain part of the pharmacokinetic variability associated with rifapentine, few studies have evaluated the contribution of genetic polymorphisms.

Endoscopic ultrasound-guided coil or glue injection in post-cyanoacrylate gastric variceal re-bleed.

Background And Aims: N-butyl-cyanoacrylate injection is recommended in bleeding/recently bled gastric varices. However, cyanoacrylate injection is associated with re-bleed in 25% to 50% of patients. Endoscopic ultrasound (EUS)-guided coil application is an emerging treatment modality for bleeding gastric varices.

Effect of antituberculosis treatment on CYP2C19 enzyme activity in genetically polymorphic South Indian Tamilian population.

Patients on antituberculosis therapy (ATT) are more prone to drug interactions in the presence of coexisting illnesses which require drug therapy. Rifampicin is a pleiotropic inducer of CYP enzymes, and isoniazid is an enzyme inhibitor. Genetic variations are common in the gene coding for CYP2C19 enzyme.

A study to explore the correlation of ABCB1, ABCG2, OCT1 genetic polymorphisms and trough level concentration with imatinib mesylate-induced thrombocytopenia in chronic myeloid leukemia patients.

Purpose: Imatinib mesylate is presently the first-line treatment for chronic myeloid leukemia (CML). Therapeutic drug monitoring (TDM) and pharmacogenetic screening is warranted for better management of imatinib therapy. The present study was framed to explore the influence of common drug transporter gene polymorphisms of ABCB1, ABCG2, OCT1 and trough level concentration on commonly occurring adverse events in CML patients treated with imatinib mesylate.

Influence of Sokal, Hasford, EUTOS scores and pharmacogenetic factors on the complete cytogenetic response at 1 year in chronic myeloid leukemia patients treated with imatinib.

Imatinib mesylate is currently considered the first-line treatment for chronic myeloid leukemia (CML). Sokal, Hasford and EUTOS are the three major risk categorization scores available for CML patients. The present study aimed to explore the influence of three risk score, genetic polymorphisms of ABCB1, OCT1, ABCG2 and trough level concentration on complete cytogenetic response at 1 year and overall survival.

Adverse drug reactions of imatinib in patients with chronic myeloid leukemia: A single-center surveillance study.

Objective: To monitor the adverse drug reactions (ADRs) associated with imatinib treatment in patients with chronic myeloid leukemia (CML) in a tertiary care hospital.

Materials And Methods: The study was carried out by the Departments of Pharmacology and Medical Oncology, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India. The study was carried out from March 2012 to February 2014.

Bronchobiliary fistula treated successfully with endoscopic microcoils and glue.

A 29-year-old male developed bronchobiliary fistula after surgery for blunt abdominal trauma with liver laceration. Despite repeated endoscopic retrograde cholangiopancreatogram (ERCP) with stenting and surgeries, the fistula did not resolve. It was successfully sealed endoscopically, using microcoils and cynoacrylate glue.
