ABSTRACT The slow progression of hepatitis C virus (HCV) infection could ultimately negatively impact pediatric patients during their lifespan. This study describes the symptomatic and pathophysiologic presentation of HCV infection in a cohort of pediatric outpatients.
HCV-positive patients were identified by diagnosis codes from outpatient visits. Demographic and pathophysiologic indicators (comorbidities, reported symptoms, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV viral load, genotype, and liver biopsy results) were collected and analyzed.
We reviewed 62 patients with HCV infection who were from 3 months and 19 years of age (M +/- SD, 12.5 +/- 5.8 years). Sixty percent presented with clinical symptoms of fatigue, joint-abdominal pain, bruising/bleeding, or other non-specific symptoms. On liver biopsy (n = 35) 80% had evidence of inflammation, 57% had fibrosis, and 9% had steatosis. All patients with steatosis or cirrhosis reported symptoms. Males were significantly more likely than women to be symptomatic (58.3% vs. 41.7%, P = 0.04). Patients with symptoms were significantly older (M = 13.5 +/- 5.2 vs. 8.9 +/- 5.5 years, P = 0.003). There was a significant inverse relationship between viral load and symptoms (chi = 4.75, P = 0.03). Patients with low viral load (<2 million copies) were 5 times more likely to have symptoms than those with high viral loads (P = 0.03). Significance was also noted between HCV genotype and ALT levels (chi = 3.72, P = 0.05). There were no significant relationships between symptom status and race, comorbidities, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV genotype, or liver histology.
Pediatric patients with HCV can have significant symptoms and physiologic liver changes related to HCV.

    ABSTRACT: Introduction Hepatitis C virus (HCV) is a major public health problem and a leading cause of chronic liver disease. An estimated 180 million people are infected worldwide. The prevalence of hepatitis C virus (HCV) infection is relatively low in children, with an anti-HCV prevalence rate of 0.2–0.4% in the Western world. Egypt has the highest prevalence of adult HCV infection in the world, averaging 15–25% in rural communities. The main (90%) HCV genotype is type 4. The magnitude of HCV infection in children is not well studied. Asymptomatic HCV infection is detectable in 2.02% of Egyptian children. Aim To study the clinical presentation and histopathological features of the liver in children with chronic hepatitis C infection. Methods The study population included 40 children from 2 to 16 years who had been diagnosed with chronic hepatitis C (HCV-RNA positive for 6 months or more by Real-time PCR) in the liver clinic at El-Shatby Children Hospital. Results Among the 40 patients’ biopsies, 26 (65%) were stage 0, 10 (25%) were stage 1, 4 (10%) were stage 2–3 (HAI). The grades of all 40 children ranged between 0 and 1 (HAI). Developing fibrosis was significantly associated with age (P = 0.015). Conclusion Children with chronic HCV infection are generally asymptomatic. Significant hepatic fibrosis was present in 10% of children with HCV infection. Fibrosis stage was significantly higher in older age children. There was no significant association between fibrosis stage and any biochemical parameter.

    ABSTRACT: The outcome of patients with hepatitis C virus (HCV) infection acquired during childhood in the absence of antiviral therapy is not clear. The purpose of this study was to review the outcome of untreated HCV acquired in childhood. Only population-based studies were included, as referred cases would be predicted to have more severe disease. A systematic review of the literature was completed up to October 2010 to identify studies where a population was screened for HCV infection that was presumably acquired during childhood. Demographical and clinical data were collected on infected patients who had not been treated with an antiviral. Primary outcome was development of a severe adverse outcome (cirrhosis, hepatoma, need for a liver transplant or liver-related death). There were 25 studies reporting a total of 733 infected patients. Liver biopsy results were provided for 180 patients (25%), revealing cirrhosis in eight (1.0% of the total and 4.0% of those who had a biopsy). None of the other patients developed a severe adverse outcome. As a result of the small number of patients with a severe adverse outcome, risk factors for HCV progression could not be identified. Although HCV can lead to liver transplantation and death during childhood, the vast majority of patients with disease acquired during childhood have slowly progressive disease. There is no clear indication for antiviral therapy in the majority of children with HCV infection.
