Gastric stem cells promote inflammation and gland remodeling in response to Helicobacter pylori via Rspo3-Lgr4 axis.

EMBO J 2022 Jun 29:e109996. Epub 2022 Jun 29.

Division of Gastroenterology and Hepatology, Medical Department, Charité - Universitätsmedizin Berlin, Berlin, Germany.

Helicobacter pylori is a pathogen that colonizes the stomach and causes chronic gastritis. Helicobacter pylori can colonize deep inside gastric glands, triggering increased R-spondin 3 (Rspo3) signaling. This causes an expansion of the "gland base module," which consists of self-renewing stem cells and antimicrobial secretory cells and results in gland hyperplasia. Read More

Pathophysiology and therapeutic management of anemia in gastrointestinal disorders.

Expert Rev Gastroenterol Hepatol 2022 Jun 20:1-13. Epub 2022 Jun 20.

Department of Internal Medicine, San Matteo Hospital Foundation, Pavia, Italy.

Introduction: Anemia is a common complication of gastrointestinal (GI) disorders, with a prevalence up to 60% in celiac disease (CeD) and inflammatory bowel disease (IBD). Iron deficiency anemia (IDA) is the most prevalent form of anemia in these conditions, but chronic inflammation and vitamin B12 deficiency represent other common contributing mechanisms, especially in IBD.

Areas Covered: We discuss the pathogenesis of anemia in various medical GI disorders, the sometime problematic distinction between IDA, anemia of inflammation (AI) and the association of the two, and therapeutic and preventive measures that can be useful for the management of anemia in GI disorders.
