The enteric nervous system of the lower esophageal sphincter area is impaired in patients with "idiopathic achalasia," and the abnormalities involve ICC and neurons in many patients. The triggering factors for these abnormalities are, however, still unknown.
Low doses of Dex (mean total dose +/- 20 mg) loaded into autologous erythrocytes were significantly more effective than sham infusions in terms of symptoms relief, endoscopic, and biochemical improvements in UC patients refractory to mesalamine. In addition, in contrast to oral prednisolone (mean total dose +/- 1 g), no steroid-related adverse events were induced.
In patients with steroid-dependent ulcerative colitis, 6-month therapy with low dose of dexamethasone 21-phosphate allowed the withdrawal of oral steroids and the reversal of steroid-related adverse events in most patients while maintaining clinical remission (ClinicalTrials.gov number, NCT01171807).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
