Abstract
Inflammatory bowel disease is a known risk factor for enteric infections such as Salmonella. This infection can affect almost all major organs. Acute Salmonella pancreatitis is a rare complication. This is the case of a 61-year-old man with ulcerative colitis who developed acute pancreatitis complicating Salmonella infection.

Denosumab Regulates Gut Microbiota Composition and Cytokines in Dinitrobenzene Sulfonic Acid (DNBS)-Experimental Colitis. Front Microbiol 2020; 11:1405. [PMID: 32670246 PMCID: PMC7331113 DOI: 10.3389/fmicb.2020.01405] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Accepted: 05/29/2020] [Indexed: 12/11/2022] Open
Abstract
The pro-inflammatory mediator receptor activator of nuclear factor-kappa B ligand (RANKL) plays a significant role in the development of rheumatoid arthritis; however, its role in inflammatory bowel disease is unknown. Genome-wide association meta-analysis for Crohn's disease (CD) identified a variant near the TNFSF11 gene that encodes RANKL and CD risk allele increased expression of RANKL in specific cell lines. This study aims to elucidate if the RANKL inhibitor denosumab can reduce the severity of experimental colitis and modify the gut microbiota composition using murine dinitrobenzenesulfonic acid (DNBS)-experimental model of colitis mimicking CD. In colitic conditions, denosumab treatment significantly decreased the pro-inflammatory cytokines IL-6, IL-1β, and TNF-α within the colonic mucosa. Moreover, colitis was accompanied by disruption of gut microbiota, and preventative treatment with denosumab modulated this disruption. Denosumab treatment also modified the alpha- and beta diversity of colonic mucosa and fecal microbiota. These results provide a rationale for considering denosumab as a future potential therapy in CD; however, more detailed experimental and clinical studies are warranted.

Abstract
Advances in genetic and epigenetic studies modified some concepts of health and disease that had been kept intact for decades. In this respect, in the last few years, microorganisms that have evolved with superior life forms for millions of years have taken an increased prominence. The genes of organisms and their microbiota constitute a microbiome that intervenes in health maintenance. The oral cavity is inhabited by a variety of microorganisms, their control aids in stabilising oral and systemic disease. The objective of this article is to update some concepts related to oral microbiome and its correlation with general and oral health.
