Insights
Bosutinib is an effective treatment for pediatric pulmonary arterial hypertension (PAH), improving long-term function and hemodynamics. While exercise capacity improvements are inconsistent, the drug is well-tolerated with fewer adverse events than in adults.
Area of Science:
- Pediatric Cardiology
- Pharmacology
- Pulmonology
Background:
- Pediatric pulmonary arterial hypertension (PAH) is a serious condition requiring effective treatment.
- Bosentan is an endothelin receptor antagonist used in adult PAH, but its use in children requires evaluation.
Purpose of the Study:
- To systematically review clinical studies on the safety and effectiveness of bosentan in pediatric PAH.
- To provide an overview of current knowledge regarding bosentan therapy in children with PAH.
Main Methods:
- A systematic literature search was conducted across MEDLINE, EMBASE, and BIOSIS from January 2000 to October 2007.
- Keywords included 'pulmonary arterial hypertension', 'bosentan', and 'pediatric patients/children'.
- 21 clinical studies (1 interventional, 11 observational, 9 case reports/series) were selected.
Main Results:
- Bosentan demonstrated improvements in long-term functional status and hemodynamics in pediatric PAH patients.
- Consistent improvement in exercise capacity was not observed.
- Combination therapy with bosentan showed promising results, but guidelines are undefined.
- Adverse events, including liver enzyme elevations, were less frequent than in adult studies.
Conclusions:
- Uncontrolled studies suggest bosentan is a well-tolerated and effective treatment for pediatric PAH.
- Further research, including controlled trials, is needed to establish definitive treatment guidelines.
Objective:
In order to provide an overview of current knowledge, the literature was systematically examined for clinical studies, which evaluate the safety and effectiveness of bosentan in pediatric pulmonary arterial hypertension (PAH).
Sources:
3 databases (MEDLINE, EMBASE and BIOSIS) were searched for the period January 2000 - October 2007 using the key words 'pulmonary arterial hypertension', 'bosentan', and 'pediatric patients/children'.
Results:
Of 165 identified publications, 21 clinical studies were selected: 1 interventional prospective, 6 observational prospective, 5 observational retrospective, and 9 case reports/case series. In the absence of controlled trials, these 21 studies represent the current evidence on the effectiveness and safety of bosentan in the treatment of pediatric PAH. Bosentan appears to improve long-term functional status and hemodynamics in children with PAH but improvement in exercise capacity is not consistently demonstrated. Promising results are reported for the combination of bosentan with other PAH-specific treatments although guidelines for instituting combination therapy have not been defined. Overall, no safety concern is raised by these studies; adverse events, including liver enzyme elevations, appear to be less frequent than reported in the adult PAH clinical trials.
Conclusion:
Recent experience, although uncontrolled, suggests that bosentan is a well-tolerated and effective therapy for pediatric PAH.
