Familial hypercholesterolemia in children and adolescents
Current Opinion in Lipidology, 11/20/2012
McCrindle BW – Children and adolescents with familial hypercholesterolemia can be identified and effective therapy with a statin initiated with consideration of the patients’ overall cardiovascular risk profile, remaining mindful of the uncertainties regarding long–term safety.
- Both general cardiovascular risk and specific familial hypercholesterolemia guidelines for children and adolescents have recently been released.
- Universal lipid screening of children has been recommended, in addition to targeted screening.
- The role of genetic testing for targeted screening and diagnostic confirmation is less clear.
- Although lifestyle therapy remains of key importance, increasing evidence of safety and efficacy support the use of statin therapy.
- Early therapy has been associated with improvements in noninvasive measures of early atherosclerosis in children, which likely can be extrapolated to improved freedom from cardiovascular disease events over the lifespan, as has been observed in adults.
- The new guidelines provide general and specific recommendations as to how family history and additional risk factors and risk conditions should be incorporated in decisions regarding initiation of statin therapy at LDL–cholesterol cutpoints.
- Emerging evidence from observational studies are beginning to address concerns regarding the initiation at young ages and longer–term efficacy and safety.
