To determine whether inactive hepatitis B surface antigen (HBsAg) carriers are at a higher risk of drug-induced hepatotoxicity than control subjects during antituberculosis treatment with standard short-course regimens of isoniazid, rifampin, ethambutol, and/or pyrazinamide. ⋯ Tuberculosis treatment in HBsAg-positive and HBeAg-negative inactive carriers could be pursued in the usual manner, using standard short-course regimens of isoniazid, rifampin, ethambutol, and/or pyrazinamide, with the condition that monthly liver function tests are performed.

The efficacy of vasopressor therapy during closed-chest resuscitation is limited and decreases over time. We previously reported that sodium-hydrogen exchanger isoform-1 inhibition during ventricular fibrillation (VF) using cariporide ameliorates ischemic contracture and enhances the efficacy of chest compression. We currently investigated whether cariporide could potentiate pressor responses to epinephrine and vasopressin. ⋯ Cariporide enhanced the hemodynamic efficacy of vasopressor agents and improved resuscitation outcomes probably as a result of enhanced forward blood flow without effect on the peripheral vasculature.
