Oral penicillin prophylaxis in children with imparied splenic function: a study of compliance
Insights
Oral penicillin prophylaxis is crucial for children with splenic dysfunction to prevent Streptococcus pneumoniae sepsis. Urine tests showed 66% compliance, suggesting this approach is feasible with proper education.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Pharmacology
Background:
- Children with defective splenic function are at high risk for severe Streptococcus pneumoniae infections.
- Oral penicillin prophylaxis is a recommended preventive measure.
- Poor patient compliance is a significant concern hindering its effectiveness.
Purpose of the Study:
- To assess the compliance rates of oral penicillin prophylaxis in children with impaired splenic function.
- To determine if compliance can be improved through patient and parent education.
Main Methods:
- Urine specimens were analyzed for penicillin presence using the Sarcina lutea disc diffusion technique.
- The study included surgically asplenic children, bone marrow transplant recipients, and children with sickle cell disease.
- Multiple urine samples were collected from participants over time.
Main Results:
- Overall, 66% of urine samples (125/188) tested positive for penicillin, indicating recent compliance.
- Compliance rates showed improvement during subsequent clinic visits.
- An intensive educational program was associated with these positive compliance findings.
Conclusions:
- Relatively good compliance rates were achieved in this cohort through consistent patient/parent education.
- Poor compliance should not be a deterrent to studying the efficacy of prophylactic penicillin in asplenic or functionally asplenic children.
- This study supports the viability of oral penicillin prophylaxis in at-risk pediatric populations.
Abstract:
One measure used to prevent overwhelming sepsis due to Streptococcus pneumoniae in children with defective splenic function is oral penicillin prophylaxis. However, a frequently cited argument against this approach is the likelihood of poor compliance. Compliance was studied by examining urine specimens for penicillin by the Sarcina lutea disc diffusion technique in 22 surgically asplenic children, two patients following bone marrow transplantation, and 38 infants and young children with sickle cell disease. Multiple specimens (mean 3.5 per patient) were examined in 43 of the children. Overall, 125/188 (66%) of the urine samples contained penicillin, indicating compliance within the previous 12 to 24 hours. Compliance tended to improve on subsequent clinic visits. These relatively good results were attributed to an intensive educational program in which repetitive efforts are made to counsel patients and parents about the risks of life-threatening infection. Poor compliance should no longer be invoked as a reason not to study the efficacy of prophylactic penicillin in functionally or surgically asplenic subjects.
