A typical parasite enteral disease is amebiasis, often known as amoebic dysentery. Any amoeba belonging to the Entamoeba genus can be the culprit. Amoebiasis may cause mild to severe symptoms, such as abdominal discomfort, bloody diarrhea, or diarrhea, or it may not cause any symptoms at all. Peritonitis may develop as a result of serious complications such as inflammation & perforation. Anemia may set in for affected individuals.
The parasite may enter the bloodstream and enter the liver, where it may spread throughout the body and result in an amoebic hepatic abscess. Abscesses in the liver can develop without any prior diarrhea. Stool samples are often examined under a microscope to make a diagnosis. It’s possible that the WBC count has risen. Blood tests that look for certain antibodies are the most reliable. Good hygiene is the key to preventing amoebiasis.
Depending on the area, there may be two clinical choices. Chloroquine, nitazoxanide, Metronidazole, dehydroemetine, or tinidazole are used to treat amoebiasis in tissue. Iodoquinoline and diloxanide furoate are used to treat luminal infestations. A number of drugs may be needed for an effective course of treatment. Treatment is necessary for infections without signs, although infected people can transmit the infection to others.
Amoebiasis can be found anywhere in the world. Between 40000 and 110000 persons, every year, pass away from amoebiasis diseases. Due to its environmental durability, ease of dispersal, resistance to chloride, and capacity to quickly spread through infected foods, E. histolytica is categorized as a category B biodefense species. E. histolytica can impact a variety of organ systems in addition to the Gastrointestinal system.
Epidemiology
Although amebiasis can occur anywhere, it is most common in underdeveloped nations due to poor sanitation and increasing fecal contamination of drinking water sources. Amebiasis is an ailment that affects over fifty million people worldwide, and it is reported to be responsible for over 100,000 annual fatalities.
Consumption of food or water infected by feces containing E. histolytica larvae is the main cause of infection. Therefore, when visiting an area where amebiasis is endemic, visitors from developing nations may contract the disease. Institutionalized people and people with impaired immune systems are also in danger.
E. histolytica can persist in the environment for a long time in its cystic condition. Additionally, it can be obtained by anal and penetrative sex, direct rectum inoculation, or through colon irrigation equipment. Despite the impact amebiasis places on the world’s healthcare system, no vaccinations or preventative drugs exist.
Anatomy
Pathophysiology
Protozoal infection E. histolytica forms pseudopods and lyses tissue in addition to causing proteolysis. The hosts are natural people. Consuming mature cysts through feces-contaminated water, hands, or food can result in an amoebic illness. The small bowel undergoes excystation of the developed cysts, releasing trophozoites, which then go to the large bowel.
Cysts are produced by binary fission as the trophozoites multiply. Both phases exit through the feces. Due to the protection offered by the cyst capsule, the cysts can persist for days to even weeks in the environment. The cyst is in charge of continuing parasite transmission. Even a small number of organisms consumed can result in illness.
Etiology
Amebiasis is brought on by the parasite Entamoeba histolytica. The intestine amoeba comes in three different species. Many symptomatic disorders are brought on by Entamoeba histolytica. Entamoeba dispar is not pathogenic, and although Entamoeba moshkovskii is becoming more prevalent, it is unknown whether it is also pathogenic.
The oral-fecal pathway is how these organisms propagate. Water and food that have been tainted frequently include infectious cysts. Rare instances of sexual transmission have also been documented.
Genetics
Prognostic Factors
Amoebic infestations have a very high risk of mortality and morbidity if neglected. In actuality, malaria is the leading cause of death.
The following demographics typically experience the most serious amoebic infestations:
Postpartum females
People who are underweight
Neonates
Pregnant women
People who take corticosteroids
People who have malignancies
The prognosis is favorable when the illness is treated, but recurrent infestations are frequent in several regions of the world. Less than one percent of patients die after receiving treatment. However, an intraperitoneal puncture may aggravate an amoebic abscess in 5 percent to 10 percent of instances, thereby raising the fatality rate.
The fatality rate for amoebic pericarditis & bronchial amebiasis is significant, topping 20 percent. Fatality rates in persons with uncomplicated disorders are currently less than one percent with intensive therapy. However, an infected amoebic hepatic abscess that ruptures has a significant mortality rate.
Indicated for extraintestinal amebiasis
1000 mg salt (with 600 mg base) orally each day for 2 days
500 mg salt (with 300 mg base) each day for 14-21 days
