Summary
Ultrasonography can detect perihepatic lymph nodes in patients with chronic hepatitis C. This finding suggests that searching for these lymph nodes may aid in diagnosing hepatitis C virus (HCV) infection.
Area of Science:
- Hepatology
- Radiology
- Virology
Background:
- Chronic hepatitis C is a significant global health concern.
- Perihepatic lymph nodes are rarely studied in relation to hepatitis C.
- Hepatitis C virus (HCV) exhibits lymphotropic characteristics.
Purpose of the Study:
- To assess the incidence of perihepatic lymph nodes in Sicilian outpatients.
- To determine the association between perihepatic lymph nodes and chronic hepatitis C.
- To evaluate the diagnostic utility of perihepatic lymph nodes in HCV screening.
Main Methods:
- Abdominal ultrasonography was performed on 1222 Sicilian outpatients.
- Perihepatic lymph nodes were identified and quantified.
- Patients were tested for anti-HCV antibodies.
Main Results:
- Perihepatic lymphadenopathy was observed in 184 out of 1222 patients.
- 142 of these patients with lymphadenopathy were positive for anti-HCV.
- A high incidence of perihepatic lymphadenopathy was confirmed in chronic hepatitis patients.
Conclusions:
- Perihepatic lymph nodes are frequently associated with chronic hepatitis C.
- The presence of perihepatic lymph nodes may indicate HCV lymphotropism.
- Screening for perihepatic lymph nodes via ultrasonography could enhance HCV detection, especially in endemic areas.
