Immunosuppression in acutely decompensated cirrhosis is mediated by prostaglandin E2.

TL;DR: Treatment with COX inhibitors or albumin restored immune competence and survival following infection with group B Streptococcus and taken together, human albumin solution infusions may be used to reduce circulating PGE2 levels, attenuating immune suppression and reducing the risk of infection in patients with acutely decompensated cirrhosis or ESLD.
Journal ArticleDOI

Crohn’s Disease: an Immune Deficiency State

TL;DR: A substantial body of data has emerged in recent years to suggest that the primary defect in Crohn’s disease is actually one of relative immunodeficiency, and the evidence for such a phenomenon is considered in contrast to alternative prevailing hypotheses and some of the potential paradoxes that it generates.
Journal ArticleDOI

TL;DR: Patients with Crohn's disease almost without exception exhibit a gross phenotype, namely a profound systemic failure of the acute inflammatory response, leading to local chronic granulomatous inflammation and compensatory adaptive immunological changes, as well as constitutional symptoms.
