What Precautions Should Be Used for a Child Whose Parent is Hepatitis C Positive?

Patient Presentation
A 2-week-old male came to clinic with his parents for his health supervision visit. He had surpassed his birth weight by 10%. The parents voiced usual concerns, but the father also asked about anything special he should do because he himself had chronic Hepatitis C. He was an older father and had contracted it through a blood transfusion during a surgery as a teenager. He only knew about it several years later when he was told he could not donate blood. He was being monitored by his physician and his wife was Hepatitis C negative during pregnancy.

The pertinent physical exam showed a healthy newborn with growth parameters in the 50-90% He had some erythema toxicum on his face. The diagnosis of a healthy newborn was made. The pediatrician wasn’t sure if there were specific recommendations for newborns and other children living in a family with a Hepatitic C positive parent. After looking at several articles online including recommendations from two professional groups in different countries, the pediatrician contacted the father. The infant had already had Hepatitis B vaccine and would receive additional doses plus Hepatitis A at the proper time. The father was told to be careful with any blood or body fluids that the child over time could come in contact with. He was also advised to not share toothbrushes or razors with the child as he grew. The pediatrician also recommended continued monitoring by the father and mother’s own physicians.

Discussion
Hepatitis C virus (HCV) is a single-stranded RNA Flavivus that was first identified in 1989 and universal screening in the blood supply was begun in 1992 in the United States. Overall incidence of acute HCV in children under age 19 is 0.1 per 100,000.

In adults, the transmission is mainly from contaminated blood and body fluids, primarily intravenous drug use. It is the most common reason for liver transplantation in adults. Of those that acquire the acute infection, about 70% go on to become chronically infected. Adults have a slow progression of their disease with 20% having cirrhosis within 20 years. Being male, older, increased duration of infection, co-infections (particularly HIV and Hepatitis B), immunosuppression, hepatotoxic drug and alcohol use all increase the risk of cirrhosis. There is a 3-4% chance of hepatocellular carcinoma developing in chronic HCV patients with cirrhosis.

In children the transmission is mainly vertical. Among family members, transmission is uncommon but inapparent or direct percutaneous or mucosal exposure to blood could occur. Of infants born to HCV-positive mothers, about 5-10% will acquire HCV. Of those that are acutely infected, only about 50-60% become chronically infected, and 25-75% of those will spontaneously resolve by 2-3 years of age. Unfortunately school age children and teenagers who acquire the infection have a natural history that is like adults. Most children who were infected at birth have no symptoms and may have normal, or elevated transaminases and viral levels. Long-term studies (10-20 years) show perinatally acquired HCV patients only have a 5-10% chance of significant fibrosis and < 5% develop cirrhosis.

Testing is by specific immunoassays which detect IgG antibodies. Those for IgM are not available. Treatment recommendations are different for children infected through vertical transmission and older children and adults. Because younger children have a high spontaneous resolution rate, treatment may not be necessary particularly since there are side effects to the medications. Recommendations are also changing particularly in the adult populations as new medications are available and are studied more. Factors regarding treatment include: age, presumed transmission method, co-infection, genotype of HCV virus (type 1 is the most common in the US), and actual liver disease. Biomarkers for liver disease are available but are not as thoroughly developed and as useful in the pediatric population.

Learning Point
For families living with a HCV+ family member some general recommendations are advised. All patients should be vaccinated against Hepatitis A and B. HCV patients should also avoid hepatotoxic medications and excessive alcohol. Universal precautions with prompt treatment and clean-up of bloody wounds should be advised. There also should be no sharing of toothbrushes and razors. Breastfeeding is not contraindicated by a HCV+ mother. Patients who are HCV+ can go to a group-based childcare facility. For HCV+ people, changes in sexual practices are not recommended if a steady partner is maintained, but the partner should be informed of the risks and ways to prevent transmission. People with multiple sexual partners are recommended to use condoms and decrease the number of partners.

Questions for Further Discussion
1. When should infants be tested for HCV if their mother is HCV positive?
2. What is the incidence of Hepatitis C in your local area?
