Role of extravariceal collateral channels in the development of portal-hypertensive gastropathy before and after sclerotherapy.

abstract：BACKGROUND:The ability of serum infliximab level to predict clinical outcome in infliximab therapy in Crohn's disease is unclear. Here, we aimed to clarify the correlation between the timing of loss of response (LOR) to treatment and a decrease in serum infliximab level, and, in addition, to identify an indicator of in...
