Deadly Bacteria Transmitted by Duodenoscopes

Duodenoscopes and endoscopes used in retrograde cholangiopancreatography are causing infections with carbapenem-resistant enterobacteriaceae (CRE) and possibly other bacteria throughout the US. While medical societies and journals scramble to increase awareness of infection risks, medical centers are already taking precautions to avoid further infections. The US Food and Drug Administration (FDA),

What are the Pyschologic Effects of Infection With Shiga Toxin-Producing Escherichia coli?

Six months after thousands of people in Germany were infected with shiga toxin–producing Escherichia coli O104, many still had poor psychological health, persistent fatigue, and impaired quality of life, according to a follow-up study in the November issue of Clinical Gastroenterology and Hepatology. The researchers identified risk factors that might

Author Q&A Series: H pylori-associated Gastric Cancer

Gastric tumors and tissues from humans and mice accumulate somatic mutations in various genes in the gastric mucosa upon Helicobacter pylori infection, researchers report in the August issue of Gastroenterology. In the study, Takahiro Shimizu et al. show that increased cytidine deaminase activity in these tissues promotes the accumulation of these mutations and might

A Window of Opportunity for Treating Patients with Cirrhosis

Despite the ability of nonselective β blockers (NSBBs) to reduce portal pressure and lower the risk of variceal hemorrhage in patients with cirrhosis, these drugs have detrimental effects on those who have developed spontaneous bacterial peritonitis, researchers show in the June issue of Gastroenterology. Variceal hemorrhage, the most common lethal complication of

What are the Effects of Albumin in Patients With SBP?

Albumin infusion prevents renal impairment and reduces mortality among patients with spontaneous bacterial peritonitis (SBP), according to a meta-analysis published in the February issue of Clinical Gastroenterology and Hepatology. SBP is a common bacterial infection among cirrhotic patients and a dangerous complication of ascites. Mortality can reach 30% despite antibiotic

Which Therapy for Helicobacter pylori Infection?

A combination of esomeprazole and 3 antimicrobial agents is less expensive and complex, and equally or more effective, than sequential regimens for eradication of  Helicobacter pylori infection, according to the July issue of Gastroenterology. H pylori infection causes stomach cancer in 20% of infected subjects, so it is important to eliminate. Although

Fecal Transplantation for C difficile Infection?

Transplantation of feces, via colonoscopy, can cure patients with recurring Clostridium difficile infection (CDI) — even those with the virulent C difficile 027 strain—according to the March issue of Gastroenterology. CDI is a common cause of diarrhea in patients taking antibiotics. Infections have recently become more frequent, severe, refractory to treatment and likely

Could Bone Marrow Cells Contribute to Stomach Cancer?

H pylori recruit bone marrow-derived cells to the gastric mucosa that contribute to tumor development, according to the February issue of Gastroenterology. H pylori infection promotes gastric carcinogenesis through many mechanisms, such as causing inflammation and producing virulence factors that alter gastric cell activity. Over time, these lead to metaplasia, dysplasia,
