Intestinal flora, probiotics, and cirrhosis.
Intestinal microflora constitutes a symbiotic ecosystem in permanent equilibrium, composed mainly of anaerobic bacteria. However, such equilibrium may be altered by daily conditions as drug use or pathologies interfering with intestinal physiology, generating an unfavorable environment for the organism. Besides, there are factors which may cause alterations in the intestinal wall, creating the conditions for translocation or permeation of substances or bacteria. In cirrhotic patients, there are many conditions that combine to alter the amount and populations of intestinal bacteria, as well as the functional capacity of the intestinal wall to prevent the permeation of substances and bacteria. Nowadays, numerous complications associated with cirrhosis have been identified, where such mechanisms could play an important role. There is evidence that some probiotic microorganisms could restore the microbiologic and immunologic equilibrium in the intestinal wall in cirrhotic patients and help in the treatment of complications due to cirrhosis. This article has the objective to review the interactions between intestinal flora, gut permeability, and the actual role of probiotics in the field of cirrhotic patients.
