Comparison of liver histology in chronic active hepatitis C and chronic active hepatitis B
1Department of Medicine, Aga Khan University Medical Center, Karachi, Pakistan.
Insights
Histological examination reveals distinct features differentiating chronic active hepatitis C (CAH-C) from chronic active hepatitis B (CAH-B). These liver biopsy findings aid in distinguishing between these two viral hepatitis types.
Area of Science:
- Hepatology
- Gastroenterology
- Pathology
Background:
- Chronic active hepatitis C (CAH-C) and chronic active hepatitis B (CAH-B) are significant causes of liver disease.
- Distinguishing between CAH-C and CAH-B is crucial for appropriate patient management and treatment strategies.
Purpose of the Study:
- To investigate and compare the specific histological features observed in liver biopsies of patients with CAH-C.
- To contrast these findings with the histological characteristics of CAH-B.
Main Methods:
- Analysis of 32 liver biopsy specimens from patients diagnosed with CAH-C.
- Comparison of these specimens with 34 liver biopsy samples from patients with CAH-B.
- Evaluation of features such as fatty change, Kupffer cell hyperplasia, and necrosis.
Main Results:
- CAH-C frequently exhibited fatty change, Kupffer cell hyperplasia, sinusoidal lymphocytosis, lymphoid follicles, and bridging necrosis.
- CAH-B cases showed a higher prevalence of focal necrosis, bile ductular proliferation, cholestasis, and ground glass cells.
- Features like sinusoidal lymphocytosis and lymphoid aggregates were rare in CAH-B compared to CAH-C.
Conclusions:
- Specific histological patterns in liver biopsies can effectively differentiate between CAH-C and CAH-B.
- Histopathological analysis provides valuable insights for diagnosing and managing chronic viral hepatitis.
Objective:
To study the histological features of chronic active hepatitis C (CAH-C) and to compare these with those of chronic active hepatitis B (CAH-B).
Methods:
Thirty-two liver biopsy specimens from patients with chronic active hepatitis and presence of antibodies to hepatitis C on second generation enzyme immunoassay were studied and compared with those in 34 patients with CAH-B. Seventeen of the 32 CAH-C patients had fully developed or developing cirrhosis of liver whereas the remainder had only chronic active hepatitis.
Results:
Among 32 patients with CAH-C, fatty change (20), Kupffer cell hyperplasia (30), sinusoidal lymphocytosis (27) lymphoid follicles aggregates in portal tracts (26) and bridging necrosis (16) were regular features. Focal necrosis, bile duct necrosis, cholestasis and ground glass cells were however seen much less often. On the other hand, in patients with CAH-B, fatty change (no patient), sinusoidal lymphocytosis (one patient) and lymphoid follicles/aggregates in portal tracts (one patient) were rare. Also, Kupffer cell hyperplasia (22 patients) was seen less commonly in patients with CAH-B as compared to CAH-C. Focal necrosis (34 patients), bile ductular proliferation (9 patients), cholestasis (17 patients) and ground glass cells (15 patients) were more prominent in CAH-B.
Conclusion:
Presence of certain histological features can help in distinguishing between CAH-C and CAH-B.
