ICD-10: B66.2

Dicroceliasis, classified under ICD-10 code B66.2, is a parasitic infection caused by the trematode (flatworm) Dicrocoelium dendriticum, commonly known as the lancet liver fluke. This infection primarily affects the liver and bile ducts of various mammals, including livestock and occasionally humans. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with dicroceliasis.

Clinical Presentation

Overview of Dicroceliasis

Dicroceliasis is typically characterized by the presence of adult flukes in the bile ducts and liver. The infection is often asymptomatic in its early stages but can lead to significant clinical manifestations as the disease progresses. The transmission occurs through the ingestion of contaminated food or water, particularly in areas where livestock are raised.

Signs and Symptoms

The clinical manifestations of dicroceliasis can vary widely among individuals, often depending on the severity of the infection and the host's immune response. Common signs and symptoms include:

• Asymptomatic Phase: Many individuals may remain asymptomatic, especially in the early stages of infection. This can lead to underdiagnosis or delayed treatment.

• Abdominal Pain: Patients may experience intermittent or persistent abdominal pain, particularly in the right upper quadrant, due to inflammation of the liver and bile ducts.

• Jaundice: Yellowing of the skin and eyes may occur if the bile ducts become obstructed, leading to cholestasis.

• Nausea and Vomiting: Gastrointestinal symptoms such as nausea and vomiting can be present, often related to the inflammatory response.

• Fever: Some patients may develop a low-grade fever as part of the body's immune response to the infection.

• Fatigue and Weakness: General malaise, fatigue, and weakness are common, particularly in chronic cases.

• Weight Loss: Unintentional weight loss may occur due to decreased appetite and malabsorption.

Complications

In severe cases, dicroceliasis can lead to complications such as:

• Cholangitis: Inflammation of the bile ducts, which can lead to infection and further complications.

• Biliary Obstruction: Chronic infection may result in scarring and obstruction of the bile ducts, leading to more severe liver dysfunction.

• Liver Damage: Prolonged infection can cause significant liver damage, potentially leading to cirrhosis in extreme cases.

Patient Characteristics

Demographics

Dicroceliasis is more commonly reported in certain populations, particularly those who are:

• Occupationally Exposed: Farmers, livestock handlers, and individuals living in rural areas where livestock are raised are at higher risk due to potential exposure to contaminated environments.

• Geographic Distribution: The infection is more prevalent in regions where the life cycle of Dicrocoelium dendriticum is maintained, particularly in Europe, parts of Asia, and North America.

Risk Factors

Several risk factors can increase the likelihood of contracting dicroceliasis:

• Consumption of Contaminated Food: Eating undercooked or contaminated food, particularly from infected animals, increases the risk.

• Environmental Exposure: Areas with high populations of snails and ants, which are intermediate hosts in the fluke's life cycle, pose a greater risk.

• Immunocompromised Status: Individuals with weakened immune systems may be more susceptible to severe manifestations of the disease.

Conclusion

Dicroceliasis, while often asymptomatic, can lead to significant clinical issues if left untreated. Understanding the signs, symptoms, and patient characteristics associated with this infection is crucial for timely diagnosis and management. Awareness of the risk factors and potential complications can aid healthcare providers in identifying at-risk populations and implementing preventive measures. If you suspect dicroceliasis in a patient, consider further diagnostic testing, including serological assays and imaging studies, to confirm the diagnosis and guide treatment.
