Clinical Description

Etiology

Chronic intestinal amebiasis is primarily caused by the ingestion of cysts of Entamoeba histolytica, typically through contaminated food or water. The organism can invade the intestinal mucosa, leading to ulceration and inflammation. While many individuals may remain asymptomatic, chronic cases can develop, particularly in immunocompromised individuals or those with poor nutritional status.

Symptoms

Patients with chronic intestinal amebiasis may experience a range of symptoms, which can vary in severity. Common manifestations include:

• Diarrhea: Often intermittent, with episodes of watery stools that may contain mucus or blood.
• Abdominal Pain: Cramping and discomfort are frequent complaints, often localized to the lower abdomen.
• Weight Loss: Due to malabsorption and decreased appetite.
• Fatigue: Resulting from chronic illness and nutritional deficiencies.
• Nausea and Vomiting: These symptoms may occur, particularly during acute exacerbations.

Complications

If not adequately treated, chronic intestinal amebiasis can lead to serious complications, including:

• Intestinal Perforation: A rare but life-threatening condition where the intestinal wall is breached, leading to peritonitis.
• Amebic Colitis: Severe inflammation of the colon, which can mimic inflammatory bowel disease.
• Extraintestinal Manifestations: Such as liver abscesses, which can occur when the parasite spreads beyond the intestines.

Diagnosis

Diagnosis of chronic intestinal amebiasis typically involves:

• Stool Examination: Microscopic identification of Entamoeba histolytica cysts or trophozoites in stool samples.
• Serological Tests: Detection of antibodies against the parasite, which can support the diagnosis, especially in cases where stool tests are inconclusive.
• Imaging Studies: Ultrasound or CT scans may be used to identify complications such as liver abscesses.

Treatment

The treatment for chronic intestinal amebiasis generally includes:

• Antimicrobial Therapy: Medications such as metronidazole or tinidazole are commonly prescribed to eliminate the parasite. Follow-up treatment with a luminal agent like iodoquinol or paromomycin may be necessary to eradicate cysts from the intestines.
