Re: Comparison with the adult guidelines

The new pediatric guidelines have proposed considering pharmacologic treatment for children with an LDL that is persistently > 160 mg/dl despite diet therapy and who are also obese. This will potentially create a dilemma for teenagers as they transition to adulthood and see an internist. Consider an obese 16 year old who does not smoke, has no hypertension, has an HDL which is above 40 mg/dl, and has adult parents who are in their 40's. The parents are both on statins for lipid control but neither has had a cardiovascular event. The child has a fasting glucose that is not in the diabetic range. Based on the new pediatric guidelines if this child has a LDL that was persistently 175 mg/dl, his/her physician would probably recommend a statin. However, if this child is seen in an internal medicine clinic two years later, based on the most recent update for the National Cholesterol Education Program (note 1), pharmacologic treatment should only be considered for an LDL greater than 190 mg/dl based on this individual's risk profile.

If this prototypical adolescent is started on a statin, an internist will be faced with the decision whether to continue this medication or reassess lipids and possibly decide the adult guidelines are more applicable at age 18. Since the adult guidelines only count hypertension, cigarette smoking, family history of premature coronary heart disease, or low HDL cholesterol (less than 40 mg/dl), and age (men older than 44, women older than 54) as cardiovascular risk factors, it is the new inclusion of obesity which is distinct from the adult guidelines and thus creates this dilemma.

One should consider that the 10 year risk of coronary death or myocardial infarction for a 20 year old man with no smoking, no treatment for hypertension and a systolic blood pressure of 135 mm Hg, and a total cholesterol of 300 mg/dl and a HDL of 40 mg/dl is only 1% (note 2). Many obese teenagers with an LDL between 160 and 190 who will be started on a statin will have a total cholesterol much lower than 300 and will also have a very low risk of a cardiac event over the next 15 years.

I look forward to further recommendations from the American College of Physicians and the National Cholesterol Education Program on what may be the best age to consider starting pharmacotherapy for elevated cholesterol.

Re: Evidence based guidelines?

I was interested in reading this clinical report of the AAP on lipid screening. I do believe like the authors that cardiovasular health of children should be taken into account and that the obesity epidemic is very concerning. I have not seen the level of evidence that can be attributed to the guideline proposed. Will we be contributing to an increased wellbeing and health of children by screening high risk individuals and treating those affected? I have not seen the data that supports this, in the article. I think that following the recommendations to screen and treat individuals according to the criterion cited here will lead to increased physician visits, lab tests and treatment based on expert opinion mainly. So increased healthcare spending for what results? Maybe the criterion could be stricter until data shows a clear benefit without too much of the side effects/danger that we are bound to see in developing humans and with the very long term duration of treatment. I believe that money would be better spent at the root of the obesity epidemic (lifestyle, activity, diet), not lower down when collateral damages are done or ongoing, especially when it has not been supported by data. I am concerned that, contrary to many authors of article in peer reviewed journals and to myself writing this commentary, there is no disclosure of competing interests by the authors. I look forward for continuing interest in this area and further development of guidelines and strategies to help physician, parents and children dealing with higher cardiovascular risks.

Re: STATINS IN CHILDREN: MORE SHADE THAN LIGHT.

Dear Editor, We read with interest the new guidelines on cholesterol screening and treatment in childhood recently issued by the American Academy of Pediatrics (1). Compared to the previous statement (2), the most important innovation regards the fact that statins are now recommended to younger patients too (8 years and older instead of 10 years and older) within the same risk categories. However, we believe that given the paucity of long term efficacy and poor safety data available to date, there are still too many concerns regarding the using of statins in children. In this term, it’s important to underline that almost all clinical trials developed in children have considered patients affected by Familial Hypercolesterolemia. In this particular condition the strong correlation with adult-onset cardiovascular disease (CVD) appeared so well demonstrated to justify a prompt pharmacological intervention (3). The same condition might be assumed individually in children with severe non familial hypercolesterolemia in presence of multiple cardiovascular risk factors. However, crucial concerns about statins treatment persist for overweight/ mildly obese children with non familial hypercolesterolemia. We believe that in this kind of patients (certainly the more one) efficacy data on primary end point (such as mortality and morbility for CVD) and long term safety data are required before recommending such an extended pharmacological approach. That especially considering the lenght of treatment (potentially for life) and therefore the possibility of adverse effects related to the exposure to a major cumulative dose in children than in adults and also problems dealing with compliance to treatment. Clinical trials in children and adolescents “have shown statins to be safe” but only in a short-term with a mean time of treatment of 27 weeks (range 6-96 weeks) (4). So far, according to the efficacy, clinical trials demonstrated the power of statins in lowering cholesterol and in some cases in improving vascular structure and function. However, we believe that the lack of strong evidence in terms of primary prevention of adult-onset CVD forces a prudential prescription of statins especially considering that the use of statins in primary prevention of cardiovascular events appears to be controversial in adults too (5). We hope, otherwise, that future data from RCT on hypercholesterolemic children/adolescents treated for long time could reinforce the statement of a prompt statin treatment in childhood according to a strong evidence of efficacy and safety profile.
