The Problem with Avandia

Warning....This is a non-genetics post (for now)

Yesterday in the media and the New England Journal of Medicine an article was released. This meta-analysis implicated a PPAR gamma activator named Rosiglitazone in the increased risk of heart attack, and death from heart attack. The risk fo heart attack was increased by 43% and the risk for death from cardiovascular causes was increased by 64%. Now before you get too crazy let's do some data analysis.

  1. The study is a meta analysis of 42 articles. This methodology is fraught with problems.
  2. The second result....64% increased risk of death is not even statistically significant P value of 0.06 with a confidence interval which includes REDUCED RISK OF DEATH.
  3. This study is a policy play, based on the fears of Vioxx.

The Gene Sherpa Says: Don't get me wrong, if you have risk of heart disease in the family, then you should not take this drug now. At least until a full proper study can be done. But please, don't freak out. Just talk to your doctor about this risk!

my husband used avandia since 1999 he had no known heart problems in february he had a heart attack at age 58 (in front on me) and after being shocked was in a coma for two weeks before dying I had a gut feeling for the last two years that although the blood sugar readings were fine something was off with the diabetes I will never know the truth, but I think the avandia contributed to this
