ABSTRACT
OBJECTIVE:
Patients with sickle cell disease (SCD) are at increased risk for invasive pneumococcal disease (IPD) caused by Streptococcus pneumoniae. Immunization and antimicrobial prophylaxis may prevent this complication, and landmark clinical trials support discontinuation of antimicrobial prophylaxis at age 5 years. However, antimicrobial prophylaxis continues in some patients indefinitely. The objective of this study was to evaluate the incidence of culture-positive IPD and other infections in the setting of penicillin prophylaxis in the pediatric SCD population.METHODS:
This was a single-center, retrospective cohort study of patients with SCD who continued antimicrobial prophylaxis with penicillin, compared with those whose antimicrobial prophylaxis was discontinued. Included patients were aged 5 to 18 years during the study period and had no history of IPD or surgical splenectomy. Patient charts were reviewed for demographics, immunizations, penicillin prescription history, and microbiologic culture data.RESULTS:
Antimicrobial prophylaxis continued beyond age 5 years in 65% of patients, a higher percentage of whom had hemoglobin SS or S beta-zero disease. No patients whose antimicrobial prophylaxis was discontinued experienced IPD; 1 patient who continued antimicrobial prophylaxis died of S pneumoniae sepsis. Rates of other infections were comparable between groups (21% in prophylaxis versus 18% in no prophylaxis).CONCLUSIONS:
These results support appropriate de-prescribing of antimicrobial prophylaxis in patients with SCD who are not at high risk for IPD. Further multicenter studies are needed to evaluate consequences of antimicrobial prophylaxis with alternative agents on antibiotic resistance, examine provider rationale for continuation of antimicrobial prophylaxis, and assess quality of life effects (e.g., medication adherence, adverse drug reactions) of antimicrobial prophylaxis.
