Overview
Yersinia enterocolitica infection primarily affects the terminal ileum and mesenteric lymph nodes, often mimicking appendicitis symptoms. It can lead to both acute and chronic complications affecting long-term survival 13.Diagnosis
Clinical Presentation: Symptoms may include abdominal pain, fever, and lymphadenopathy, often mimicking appendicitis 1.
Laboratory Tests: Serological tests (antibody response) and culture of stool or blood samples are crucial for diagnosis 13.
Imaging: Abdominal imaging may show ileitis or lymphadenitis, aiding in differential diagnosis 1.
Geographic Considerations: Prevalence varies by region; testing should be guided by epidemiological context 1.Management
Antibiotics: First-line treatment often includes trimethoprim-sulfamethoxazole or ciprofloxacin for systemic infections 3.
Supportive Care: Symptomatic treatment for fever and pain management is essential 3.
Monitoring: Close monitoring for complications such as chronic liver disease, especially in patients with prolonged symptoms 3.Special Populations
Chronic Complications: Patients with chronic liver disease post-infection have significantly higher mortality rates 3.
Long-term Follow-up: Increased vigilance and follow-up are recommended for elderly patients due to higher risk of chronic complications 3.Key Recommendations
Diagnose Y. enterocolitica infection through serological testing and culture, considering regional prevalence (Evidence: Moderate 1).
Initiate antibiotic therapy with trimethoprim-sulfamethoxazole or ciprofloxacin for systemic infections (Evidence: Expert opinion 3).
Implement long-term monitoring for chronic complications, particularly in elderly and those with liver disease (Evidence: Moderate 3).References
