Objective: The aim of this work is to assess the pattern of chronic HCV infection in children of our locality as regards, clinical, laboratory and pathological aspects of this disease. We will also evaluate the importance of immunohistochemical diagnosis of chronic HCV infection.

Methods: This study included 15 patients with chronic hepatitis C virus (HCV) disease, Their ages ranged from 5 to 13 years. All included patients were positive for HCV antibodies with persistently high or fluctuant alanine aminotrasferase (ALT) for at least 6 mo.

On admission all patients were subjected to full history and thorough clinical examination, abdominal ultrasound and laboratory investigations including CBC and liver function tests. Liver biopsy specimens were taken from all included patients for histopathological grading and staging. Liver specimens were subjected to immunohistochemical studies by use of monoclonal antibody TORDJI-22.

Results: Risk factors were encountered in 60% of our patients. Blood transfusion and exposure to injuries were the most important risk factors. Fatigue or generally unwell was a common complaint (53.3%), while 26.67% of patients were asymptotic. Most of our patients (60%) had mild elevation of ALT enzyme and were classified as having mild liver disease while 33.33% of patients had moderate disease.

Histopathological grading and staging were done and most of our patients were classified as having grade 1 and stage 1`. Liver cirrhosis was not encountered in any patient. Significantly higher levels of ALT were found in patients with grade 2 (185.75±68.16) than those with grade 1 (69.75±29.07) (p0.05). Again, patients with grade 3 had significantly higher levels of ALT than those with grade 1 (255.67±160.02 and 69.75±29.07 respectively)(p<0.05). TORDJI-22 immunopositivity was detected in 53.3% of studied liver specimens.

Conclusions: In conclusion, chronic HCV infection in children is an important health problem. Histopathological grading and staging are important for these children to assess the severity of infection. Immunohistochemistry by the use of TORDJI-22 is an important diagnostic tool of HCV infected hepatocytes in anti- HCV positive patients. It may reflect the cytotoxicity of HCV secondary to high levels of virus replication or prolonged infection. However, Further studies on a large number of patients is recommended to confirm the sensitivity of this antibody and follow up studies to clarify its prognostic value.
