Assessment of hepatic fibrosis in pediatric cases with hepatitis C virus in Egypt.

AIM: To assess hepatic fibrosis and factors associated with its progression in children with HCV infection. METHODS: At the Hepatology Unit, Cairo University Children's Hospital, a single liver biopsy was performed to 43 children with HCV infection after an informed consent between 1998-2004. Their mean age at liver biopsy was 8.67 +/- 4.3 years. RESULTS: Among the 43 patients' biopsies, 12 (27.9%) were having no fibrosis, 20 (46.5%) mild fibrosis and 11 (25.6%) moderate to severe fibrosis. The median time for development of fibrosis was estimated to be 5.5 years. Developing fibrosis was significantly associated with shorter duration from first detected ALT elevation to biopsy (12 mo vs 1.2 mo, P=0.015) and having higher levels of direct serum bilirubin (0.3 mg/dL vs 0.5 mg/dL, P=0.048). No association was found between fibrosis stage and the presence of co-morbid conditions (P=0.33). CONCLUSION: Hepatic fibrosis was present in 72.1% of children with HCV infection. The development of fibrosis was associated with higher levels of direct serum bilirubin. There was no significant association between fibrosis and age, duration of infection, risk factors, co-morbid conditions and most biochemical parameters.

Patterns of hepatitis B infection in Egyptian children in the era of obligatory hepatitis B vaccination.

BACKGROUND AND STUDY AIMS: Mass compulsory HBV vaccination was applied in Egypt in 1992. The first dose of vaccine is administered at 2 months of age and routine screening of pregnant women for HBsAg is not applied. We aimed to evaluate the pattern of HBV infections after the implementation of HBV vaccination in Egyptian children. PATIENTS AND METHODS: Fifty-six children with HBV infection presented to the Paediatric Hepatology Unit, Cairo University Children's Hospital, over the period from 1992 to 2006. Their data were reviewed for risk factors, clinical, serological and histopathological profiles. These cases were followed-up for 6.3 ± 3.4 years. The data of those born before 1993 (did not receive HBV vaccine) (group I) was compared to those who received the vaccine (group II). RESULTS: Sixty percent of HBV infected cases were born before 1993. Comparison of data of both groups revealed: (1) A significant younger age of onset in group II (3.34 ± 3.31 years vs. 9.84 + 2.95 years; p ≤ 0.01). (2) Vertical transmission was a significant risk factor in group II. (3) Chronic hepatitis developed in almost half of cases in both groups but cirrhosis was diagnosed only in 4 cases (all from group I) (p=0.04). CONCLUSION: Vertically transmitted HBV infection is becoming an important risk factor for acquisition of HBV among children born after the era of mass vaccination in Egypt. Mass screening for HBsAg of pregnant Egyptian women and/or giving a birth dose of HBV vaccine is becoming mandatory with the increased incidence of vertical transmission.
