Disease-modifying effect and long-term safety of belimumab in patients with systemic lupus erythematosus: A single-center retrospective study.

Background: Disease modification in systemic lupus erythematosus (SLE) is important for minimizing disease activity while limiting treatment-associated toxicities. Belimumab can be used as a remission-induction/maintenance systemic lupus erythematosus therapy; however, its disease-modifying effects are unclear. We aimed to determine these effects in patients with systemic lupus erythematosus.

Potential feasibility of a novel over-the-wire microelectrode catheter for recording coronary sinus electrograms in patients with cardiac resynchronization therapy devices.

The placement of an electrode catheter into the coronary sinus (CS) is important for differentiating multiple atrial tachycardias (ATs). Based on its high selective performance in placement into small veins, inserting a novel over-the-wire 2.7Fr microcatheter (EPstar Fix AIV; Japan Lifeline) into the CS may be feasible even in patients implanted with a cardiac resynchronization therapy device.
