ICD-10: B66.8

ICD-10 code B66.8 refers to "Other specified fluke infections," which are a subset of parasitic infections caused by flukes, a type of flatworm. These infections can affect various organs and systems in the body, leading to a range of clinical manifestations. Below is a detailed overview of this diagnosis code, including its clinical description, potential causes, symptoms, and treatment options.

Clinical Description

Fluke infections are primarily caused by trematodes, which are parasitic flatworms. The most common flukes that infect humans include species from the genera Fasciola, Clonorchis, and Schistosoma. While some fluke infections are well-documented, the term "other specified fluke infections" encompasses those that do not fall under the more commonly recognized categories.

Types of Fluke Infections

1. Fascioliasis: Caused by Fasciola hepatica, this infection primarily affects the liver and bile ducts. It is often contracted through the consumption of contaminated water plants.

2. Clonorchiasis: Resulting from Clonorchis sinensis, this infection is associated with the consumption of undercooked freshwater fish and can lead to cholangitis and other biliary tract diseases.

3. Schistosomiasis: Although primarily classified under a different code, certain species of Schistosoma can also be included in this category when they present atypically.

4. Other Specified Infections: This includes less common fluke infections that may not be as widely recognized or documented in clinical literature.

Symptoms

The symptoms of fluke infections can vary significantly depending on the type of fluke and the organs affected. Common symptoms may include:

• Abdominal Pain: Often localized to the upper right quadrant in liver fluke infections.
• Nausea and Vomiting: These symptoms can occur due to gastrointestinal involvement.
• Diarrhea: May be present, particularly in cases involving the intestines.
• Fever and Chills: Systemic symptoms can occur, especially in acute infections.
• Jaundice: This may develop in cases where the bile ducts are obstructed.

Diagnosis

Diagnosis of fluke infections typically involves:

• Clinical History: A thorough history of exposure to contaminated water or food sources.
• Serological Tests: Blood tests to detect antibodies against specific fluke species.
• Stool Examination: Microscopic examination of stool samples to identify eggs or larvae.
