Siblings tend to have a similar response to antiepileptic drugs (AEDs) suggests a study that compared drug response in sibling pairs. Details of the investigation include the following:
- Investigators collected records from a single-center database that included patients with a diagnosis of epilepsy in which their last names, addresses, and parents’ names were matched to determine the existence of siblings with the same disease.
- Twenty-eight sibling pairs were identified, along with 2 sibling trios with epilepsy.
- Seventeen of the sibling pairs had been taking the same initial AED, while 15 pairs had the same type of epilepsy.
- When at least one sibling in a pair improved on an initial AED, the other sibling was more likely to respond if they were taking the same AED compared with those who were taking a different AED.
- While a positive response to an AED predicted success in a sibling taking the same drug, investigators pointed out that their study was retrospective and involved a small sample, which is why they recommended larger prospective trials.
