Cholesterol Drugs Tied to Birth Defects
By Serena Gordon HealthDay Reporter
Researchers from the U.S. National Institutes of Health found that statin use during the first trimester of pregnancy is associated with severe central nervous system defects and limb deformities.
Their findings, published in a research letter in the April 8 issue of the New England Journal of Medicine, showed that 20 of 52 babies exposed to statins in the womb were born with malformations. (THAT IS HALF!!)
“We can’t tell whether the defects were caused by the use of statin medications, but other birth defect studies suggest that these are the kinds of problems that occur if the embryo does not get enough cholesterol in early pregnancy to develop normally,” said one of the study’s authors, Dr. Maximilian Muenke, a senior investigator and chief of the medical genetics branch at the National Human Genome Research Institute in
These medications are already considered contraindicated in pregnancy and the Food and Drug Administration requires that all statin prescriptions carry a warning about taking them during pregnancy, Muenke added.
“Statins are very good for general health. But there’s a lot we don’t know about their safety in pregnancy because there is no national system for monitoring the safety of drugs during pregnancy,” Green noted.
Muenke and NIH colleague Dr. Robin Edison reviewed the 52 reports to the FDA of statin exposure in the first trimester of pregnancy that occurred from 1987 through 2001.
Of the 20 babies born with malformations, five had severe central nervous system defects, and five had malformed limbs. One baby had both, according to Muenke. There were also two cases of a very rare birth defect called holoprosencephaly, which occurs when the brain fails to divide properly.

“These are such very rare birth defects that one would not expect to find the number we found in a population this small,” Muenke said.
Green said the study highlights the need for a more comprehensive reporting system for medication use during pregnancy. With such a system, health-care providers could know if a medication was safe for use during pregnancy or not.
“For most drugs, we can’t say for sure if they’re safe. That often leads to under-treatment,” Green said.
“Our study supports the need for [warning labels on statins], and it points to the need for larger, controlled studies to better define the risks of using statins in pregnant women,” Muenke added.
“In the meantime, if a woman becomes unexpectedly pregnant while taking statins, she should immediately consult with her physician,” he said. To learn more about medications and pregnancy, visit the March of Dimes (www.modimes.org ) or the U.S. Food and Drug Administration (www.fda.gov ).

Niacin (vitamin B 3) was the initial best cholesterol lowering agent back in the 1950’s in that it lowers total cholesterol, lowers the “bad” LDL cholesterol and raises the “good” HDL cholesterol (it also protects against cancer and diabetes but that is another story). Initially, other drugs were tested against niacin but the all did so poorly that by the 1970’s drug companies opted from then on to only test their new drug against other drugs. No one wanted to have their drug compared to natural niacin. Like most of what we offer at the Weeks Clinic, the natural “niacin option” is safer, more effective and …..cheaper. Hmmm. That spells trouble for the pharmaceutical business, it would seem.
