A 3-year-old child with sickle cell disease is brought for a well-child visit. What is an appropriate intervention to decrease the child’s risk of infection?

• A. Obtain a CBC with differential and platelet count every 6 months
• B. Obtain a yearly Hgb electrophoresis and administer the pneumococcal vaccine annually
• C. Prescribe penicillin 20 mg/kg and administer Hib at this visit
• D. Continue penicillin prophylaxis 20 mg/kg and administer the pneumococcal vaccine at this visit

Answer: (D)

In sickle cell disease, the spleen often becomes nonfunctional early in life, leaving the child highly susceptible to serious infections from encapsulated bacteria, especially Streptococcus pneumoniae. The main preventive measures are penicillin prophylaxis and pneumococcal vaccination. Continuing penicillin prophylaxis through early childhood significantly lowers the risk of invasive pneumococcal disease during the period of highest vulnerability. Administering the pneumococcal vaccine at this visit helps boost protection against pneumococcus, which is crucial for a child with functional asplenia. Hib vaccination is important for protection against Haemophilus influenzae type b, but most children have completed this series by this age. The key infection-preventive steps here are keeping penicillin prophylaxis ongoing and ensuring pneumococcal vaccination is up to date.
