High total cholesterol in child

Hi,

My nine year old son has a total cholesterol which is higher than the
normal range (I think it is 5.2, we are from canada in case the scale
look different from yours). After further blood test it turned out his
HDL, the good cholesterol is almost double the average kid ! (I think
the reading is 2.8) On the other hand his LDL and trigericide
(spelling?) are withing the normal range, about half way between the
upper and lower limit for what is considered 'normal'. The total
cholesterol to HDL ratio is 2.

>From my lay person's perspective since the reason why his total
cholesterol seem high was because of his extra-ordinarily high HDL.
But the pediatrician said we should still be concerned because the
'total cholesterol' is above normal, and he has a higher risk of
coronary disease just because of that.

On the contrary, our family physician does not think my son's case
needs any special attention since it is the HDL that is high, not the
other cholesterols.

Who was right and who should I listen to ?

It is hard to know.

Apparently there is increasing feeling that the simple dichotomy of
HDL = good and LDL = bad is an over-simplification.

It sounds like the child's situation is "not normal" (meaning simply,
not common). So it is hard to know how it fits in. It would help if
one knew why HDL was so high, but that may be hard to determine.

Is it common there to be measuring the cholesterol of a 9 year old? Or
was there some reason it came up? That might matter.

Perhaps you could get the two docs to tell you more about how they see
this. If you sound like you want to understand it better, and won't
panic at uncertainty (and uncertainty is the one thing that is
certain), perhaps they will help.

re your spelling question: trigericide should be triglyceride -- which
you may find useful as a search term. Ordinary fat or oil is mostly
triglycerides -- glycerol with three fatty acids attached.

~~~~~~~~~~~~~~~~~~~~~~~~

bob,
Great post. The original poster should consider having the child retested
at another clinic or hospital since there may have been errors made
related to the first blood test. If the results are the same, a liver
function test should also be done to rule in or rule out liver problems
since the liver is involved related to cholesterol levels.

Thanks everyone for responding. My son's high total cholesterol was
discovered by accident during a regular blood test. He is not over-
weight, eats healthy and does exercise regularly. When the
pediatrician saw the result he ordered another blood test for
different kinds of cholesterols.

Is there any concensus in the medical profession about whether high
HDL can lead to problems ?

Online sources say 8-10% of the population has it.

In general it is cardioprotective but if it is high due to certain
mutations it could actually be artherogenic.  This is an area of
controversy.  For example some mutations in the CETP (target of the
recent failed Pfizer drug) are linked to high HDL levels and increased
heart disease risk.  See for example:

http://circ.ahajournals.org/cgi/content/full/101/16/1907

I would not be alarmed.  I think the physician who wanted more tests may
just be being very thorough.  You would need to go to a very advanced
testing environment (Cleveland clinic type place) to really be able to
get definitive answers.

Try asking your question (mention CETP mutants so they don't give you
off the cuff high HDL is good) and ask them whether it is worth
evaluating further and how to proceed.   on:
