[Post-splenectomy infections and Pneumococcus vaccination in paediatric surgery (author's transl)]
Insights
Children with spleen issues face higher pneumococcal infection risks. Vaccination combined with penicillin prophylaxis offers crucial protection, especially for those under 2 years old.
Area of Science:
- Pediatrics
- Infectious Diseases
- Immunology
Context:
- Children with compromised splenic function, due to splenectomy or congenital asplenia, exhibit increased morbidity and lethality from pneumococcal infections.
- Vaccination with polyvalent vaccines is recommended for children over 2 years old who have undergone splenectomy or have congenital asplenia.
- Current vaccination provides only 80% protection, necessitating additional preventive measures.
Purpose:
- To outline strategies for managing pneumococcal infection risk in asplenic children.
- To emphasize the importance of combining vaccination with antibiotic prophylaxis.
- To explore potential improvements in vaccine efficacy for younger children.
Summary:
- Pneumococcal vaccination is recommended for children over 2 with splenic dysfunction, but offers limited protection.
- Combining vaccination with 3-5 years of penicillin prophylaxis is advised.
- Research is exploring enhanced vaccine immunogenicity for children under 2 and splenic tissue re-implantation.
Impact:
- Highlights the need for comprehensive management of pneumococcal infections in vulnerable pediatric populations.
- Informs parents and physicians about the limitations of current vaccination strategies.
- Suggests future directions for improving prevention and treatment of pneumococcal disease in children with asplenia.
Abstract:
Morbidity and lethality rates in pneumococal infections are higher among children with underlying diseases associated with restricted or absent splenic function. Vaccination with polyvalent vaccine is indicated in all children who are more than 2 years old and who have been splenectomized or have a congenital asplenia. Since protection by vaccination is 80% only, we combine the vaccination with penicillin prophylaxis for at present at least three to five years after splenectomy and draw the express attention of parents and family physicians to the limited nature of protection afforded by vaccination. An increase in the immunogenicity of polysaccharid antigen vaccine might lead to successful vaccination of children below 2 years of age who are notable for a particularly high risk of infection. First reports have been published in literature on the possibility of re-implantation of splenic tissue after post-traumatic rupture (17, 27, 28) so that it may become possible to employ this method additionally to pneumococcus vaccination. In case of haematological indication for splenectomy this should be postponed as far as possible until the child has completed his fifth year of life.
