Real-world evidence on adherence, persistence, switching and dose escalation with biologics in adult inflammatory bowel disease in the United States: A systematic review.

What Is Known And Objective: The application of biologics to treat inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is well established. Our aim was to characterize the most recent five years of data on rates of adherence, persistence, switching and dose escalations with biologics used to treat IBD in the United States.

Methods: We systematically reviewed electronic databases MEDLINE, MEDLINE In-Process, EMBASE and Cochrane Library for 2012-2017 as well as conference proceedings for 2016-2017 published in English.

Ethanol alters local cellular levels of (3α,5α)-3-hydroxypregnan-20-one (3α,5α-THP) independent of the adrenals in subcortical brain regions.

The neuroactive steroid (3α,5α)-3-hydroxypregnan-20-one (3α,5α-THP or allopregnanolone) is a positive modulator of GABAA receptors synthesized in the brain, adrenal glands, and gonads. In rats, ethanol activates the hypothalamic-pituitary-adrenal axis and elevates 3α,5α-THP in plasma, cerebral cortex, and hippocampus. In vivo, these effects are dependent on both the pituitary and adrenal glands.
