Introduction

Thalidomide is a drug that was introduced on to the market on October 1, 1957 in West Germany. Thalidomide soon became a drug prescribed to pregnant women to combat symptoms associated with morning sickness.


Thalidomide Structure

When taken during the first trimester of pregnancy, Thalidomide prevented the proper growth of the foetus resulting in horrific birth defects in thousands of children around the world.

It was the linking of newborn abnormalities with the taking of thalidomide by an Australian clinician, William McBride, that identified it as a teratogenic agent causing a "thalidomide embryopathy".

Children were born with limb and other defects, mainly in first world countries, in the late 1950's and early 1960's and became known as "Thalidomide babies". (More? [../Notes/skmus2.htm#LIMB%20REDUCTION Musculoskeletal Abnormalities - Limb Reduction])

Not all species embryos are affected by the drug in the same way, with human and rabbit being most susceptible to the teratogenic effects. In addition, the effect on human development is also dependent upon the time and dose of the drug exposure, the "critical periods".

More recent research has shown a clinical revival for thalidomide in its use in non-pregnant women during cancer chemotherapy.

Some Recent Findings

Knobloch J, Rüther U. Shedding light on an old mystery: Thalidomide suppresses survival pathways to induce limb defects. Cell Cycle. 2008 Feb 14;7(9)

"Many hypotheses have been proposed to explain the molecular mechanism of thalidomide teratogenicity, in particular regarding to limb defects. Most experimental evidence in vivo has been provided for a model that suggests the generation of oxidative stress by thalidomide with subsequent down-regulation of Wnt and Akt survival pathways. ...We extend this model by presenting new data demonstrating an involvement of the transcription factors Tbx5 and Sall4 in thalidomide-induced molecular pathology."

"The Thalidomide Victims Association of Canada (TVAC) was founded in 1988 and is the only organization in North America to work with and for Thalidomide victims. Our mission is to empower our members and to improve their quality of life through various programs and customized services. With the return of Thalidomide on the market, TVAC also took on the mandate of informing the public on the devastating effects of this medication and to promote awareness and caution when using any teratogenic products currently available".
