What are the symptoms of amoebiasis?

Amoebiasis, caused by the protozoan Entamoeba histolytica, presents with a range of symptoms that can vary from mild to severe. The following key insights have been synthesized from the provided research papers:

Chronic abdominal pain and frequent bowel disturbances are common symptoms that may be misdiagnosed as non-dysenteric intestinal amoebiasis; however, these symptoms are often not associated with E. histolytica infection and are more likely to be indicative of irritable bowel syndrome (IBS).
Severe cases of amoebiasis can lead to complications such as multiple colonic and ileal perforations, which may initially present with symptoms similar to inflammatory bowel diseases like Crohn's disease.
Thoracic symptoms, including cough and chest pain, can occur in cases of hepatic amoebiasis and may lead to a delay in appropriate treatment if not recognized early.
Common symptoms of amoebiasis include cramping, abdominal pain, watery or bloody diarrhea, and weight loss, with some patients remaining asymptomatic.
Amoebic dysentery, a severe form of amoebiasis, is characterized by loose, frequent stools containing blood and mucus.
Neurohumoral alterations in patients with amoebiasis can lead to increased levels of certain neurohumors and cortisol, which may be a nonspecific response to the stress of the disease.
Amoebiasis can also be transmitted sexually, leading to symptoms such as liver abscesses or chronic diarrhea, even in individuals who have never traveled to endemic areas.

In conclusion, amoebiasis can manifest with a variety of symptoms ranging from abdominal pain and diarrhea to more severe complications like organ perforations and liver abscesses. While some cases may mimic other gastrointestinal disorders such as IBS or inflammatory bowel diseases, it is important to consider amoebiasis in the differential diagnosis, especially in patients with relevant risk factors or travel history. Accurate diagnosis is crucial for appropriate treatment and prevention of complications.

Does non-dysenteric intestinal amoebiasis exist?

Non-dysenteric intestinal amoebiasis is extremely rare, and most chronic abdominal pain and frequent bowel disturbances are likely to be caused by irritable bowel syndrome (IBS).

Multiple colonic and ileal perforations due to unsuspected intestinal amoebiasis-Case report and review.

Invasive intestinal amoebiasis should be considered as a differential diagnosis for adult IBD-like symptoms, even with suggestive endoscopic findings of Crohn's-like ulcers.

Intrathoracic manifestations of amoebiasis.

Thoracic amoebiasis presents as a febrile illness with cough, chest pain, and point tenderness in the intercostal space or right upper quadrant of the abdomen, and should be considered in the evaluation of obscure, right-sided respiratory symptoms in endemic areas.

Amoebiasis: An Infectious Disease Caused by Entamoeba histolytica

Amoebiasis is an infectious disease caused by Entamoeba histolytica, with common symptoms including cramping, abdominal pain, diarrhea, and weight loss.

Amoebiasis

Amoebiasis is a complex disease involving the large bowel, liver, and occasionally other organs, caused by the protozoan parasite Entamoeba histolytica.

Neurohumoral alterations and their role in amoebiasis

Amoebiasis patients experience increased levels of neurohumoral metabolites, suggesting a nonspecific response to stress and parasitic infestation, but these changes return to normal after one month of treatment.

An underestimated sexually transmitted infection: amoebiasis

Sexual transmission of amoebiasis can occur in non-endemic areas, even in individuals who have never travelled abroad, and should be considered in cases of liver abscesses or chronic diarrhoea.

The pathogenesis of amoebiasis.

Amoebiasis is a worldwide disease caused by the motile trophozoite of Entamoeba histolytica, which lives in the large intestine and causes luminal amoebiasis, with no clinical signs or symptoms, and invasive amoebiasis,
