[Features of intestine microbiocenosis and systemic inflammation factors in chronic heart failure patients]
Aim:
Intestine microbiocenosis structure, endotoxinemia level, C-reactive protein (CRP) and TNFalpha concentration in chronic heart failure patients (CHF) were studied depending on disease severity.
Materials And Methods:
Clinical, echocardiographic and laboratory examination of 104 patients was performed: 75 CHF patients and 29 healthy volunteers. Laboratory examination included bacteriologic analysis of feces for dysbiosis, determination of endotoxin (ET) levels, CRP and TNFalpha levels in blood serum.
Results:
More expressed alterations in large intestine microbiocenosis and an increase of endotoxinemia and systemic inflammation factors (TNFalpha and CRP) levels were detected in patients with CHF in comparison to individuals without circulatory system pathology. CHF progression is associated with an increase of intestine dysbiosis, and ET, TNFalpha and CRP levels in blood.
Conclusion:
Endotoxinemia in CHF patients, that is caused by an increase in intestine wall permeability during development of venous congestion in systemic circulation, results in immune system activation manifesting in an increase of systemic inflammation factor level in blood that can aggravate the CHF course.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
