Dysentery

From Wikipedia, the free encyclopedia

Dysentery (formerly known as flux or the bloody flux) is an infection of the digestive system that results in severe diarrhea containing mucus and blood in the feces and is typically the result of unsanitary water containing micro-organisms which damage the intestinal lining. There are two major types of dysentery due to micro-organisms: amoebic dysentery, and bacillary dysentery mainly due to one of three bacteria. Dysentery can also be caused by certain medications; for example, some steroids can impact bowel movements.[1]

[edit] Amoebic dysentery

Main article: Amoebiasis

Amoebic dysentery (or amebic dysentery) is caused by the amoeba Entamoeba histolytica.

Amoebic dysentery is transmitted through contaminated food and water. Amoebae spread by forming infective cysts which can be found in stools and spread if whoever touches them does not sanitize their hands. There are also free amoebae, or trophozoites, that do not form cysts.

Amoebic dysentery is well known as a "traveler's dysentery" because of its prevalence in developing nations, or "Montezuma's Revenge" although it is occasionally seen in industrialized countries. Liver infection, and subsequent amoebic abscesses can occur.

[edit] Bacillary dysentery

Bacillary dysentery is mostly commonly associated with three bacterial groups:

[edit] Symptoms and complications

Symptoms include frequent passage of feces/stool, loose motion and in some cases associated vomiting. Variations depending on parasites can be frequent urge with high or low volume of stool, with or without some associated mucus and even blood.

Once recovery starts, early refeeding is advocated avoiding foods containing lactose due to temporary [can persist for years] lactose intolerance.[2][3]

[edit] Treatment

See also: Amoebiasis Treatment

The first and main task in managing any episode of dysentery is to maintain fluid intake using oral rehydration therapy. If this can not be adequately maintained, either through nausea and vomiting or the profuseness of the diarrhoea, then hospital admission may be required for intravenous fluid replacement. Ideally no antimicrobial therapy is started until microbiological microscopy and culture studies have established the specific infection involved. Where laboratory services are lacking, it may be required to initiate a combination of drugs including an amoebicidal drug to kill the parasite and an antibiotic to treat any associated bacterial infection.

Amoebic dysentery can be treated with metronidazole. Mild cases of bacillary dysentery are often self-limiting and do not require antibiotics,[4] which are reserved for more severe or persisting cases; campylobacter, shigella and salmonella respond to ciprofloxacin or macrolide antibiotics.[4]
