ICD-10: A06.2

A06.2 refers to Amebic nondysenteric colitis, a condition characterized by inflammation of the colon caused by the protozoan parasite Entamoeba histolytica. This specific ICD-10 code is used to classify cases where the infection leads to colitis without the severe symptoms typically associated with dysentery, such as bloody diarrhea.

Clinical Description

Etiology

Amebic nondysenteric colitis is primarily caused by Entamoeba histolytica, which is transmitted through the fecal-oral route, often via contaminated food or water. The parasite can invade the intestinal lining, leading to inflammation and ulceration of the colon. While many individuals may be asymptomatic carriers, some may develop gastrointestinal symptoms.

Symptoms

Patients with amebic nondysenteric colitis may experience a range of symptoms, which can vary in severity. Common symptoms include:

• Abdominal pain: Often crampy and may be localized or diffuse.
• Diarrhea: Typically non-bloody, which distinguishes it from dysentery. The stool may be loose and watery.
• Nausea and vomiting: These symptoms can accompany abdominal discomfort.
• Weight loss: Chronic infection may lead to malnutrition and weight loss due to decreased appetite and nutrient absorption.
• Fatigue: Resulting from dehydration and nutritional deficiencies.

Diagnosis

Diagnosis of amebic nondysenteric colitis typically involves:

• Stool examination: Microscopic analysis of stool samples can reveal the presence of E. histolytica cysts or trophozoites.
• Serological tests: Blood tests may be conducted to detect antibodies against E. histolytica.
• Imaging studies: In some cases, imaging such as ultrasound or CT scans may be used to assess the extent of colonic involvement.

Treatment

The treatment for amebic nondysenteric colitis generally includes:

• Antimicrobial therapy: Medications such as metronidazole or tinidazole are commonly prescribed to eliminate the parasite.
• Supportive care: This may involve rehydration and nutritional support, especially in cases where diarrhea is significant.

Complications

While amebic nondysenteric colitis is less severe than dysentery, complications can still arise, including:

• Dehydration: Due to prolonged diarrhea.
• Intestinal perforation: Rarely, severe cases can lead to perforation of the colon, which is a medical emergency.
• Secondary infections: The compromised intestinal lining may increase the risk of bacterial infections.

Conclusion

A06.2, or amebic nondysenteric colitis, is an important diagnosis in the context of gastrointestinal infections. Understanding its clinical presentation, diagnostic methods, and treatment options is crucial for effective management. Early recognition and appropriate treatment can prevent complications and improve patient outcomes. If you suspect a case of amebic nondysenteric colitis, timely medical intervention is essential to ensure proper care and recovery.
