Use of quinolones in the treatment of gastrointestinal infections
- 44 Downloads
Bacterial enteropathogens are responsible for between 40 % and 80 % of diarrheal illness depending upon the age of the persons affected and geographic area where illness occurs. Antibacterial agents will shorten the illness associated with enteric infection caused by enterotoxigenicEscherichia coli, Shigella spp. andCampylobacter jejuni. These drugs also are effective in the therapy of certain clinical conditions (presumably because they are due to the same agents) which are characterized by moderate to severe diarrhea with one or more of the following: high fever, dysentery (passage of bloody mucoid stools), or high leukocyte counts in stools. Antimicrobial agents are also effective in the therapy of travelers' diarrhea. The quinolone drugs have several advantages in the management of bacterial diarrhea where strains causing illness from nearly all regions of the world will show general susceptibility: high concentrations are achieved in the intestinal lumen following oral administration and resistance development is unusual. A quinolone probably represents the optimal agent for therapy of bacterial diarrhea in adults in areas where trimethoprim-resistant enteric pathogens are common.
