New and important hypothesis?
Commenting on the study, Daniel Goldenholz, MD, PhD, instructor in the Division of Epilepsy, Beth Israel Deaconess Medical Center, Boston, said priapism is not something that practicing epileptologists are instructed “to look for.”
He noted that “the idea of looking for a hidden signal in a massive database like this is very appealing” because it could reveal patterns that were previously undetected.
However, the event rate in the study suggests priapism, which “in the right context would be considered a medical emergency, [is] relatively uncommon,” said Dr. Goldenholz, who was not involved with the research.
He noted that medications that could cause priapism, “such as antidepressants, blood pressure meds, and anticoagulants,” are commonly used by many people – including those with epilepsy.
It is consequently possible that “the finding from this study can be explained by comorbid medical problems,” Dr. Goldenholz said. This is particularly likely because many of the AEDs in question “have been on the market for decades,” he added.
“If a seemingly dangerous symptom would be happening as a result of one of these medications, ,” he said.
Still, Dr. Goldenholz noted that it is “possible that these authors have a new and important hypothesis which must now be tested: Does priapism occur in patients with antiseizure medications when other causes are already ruled out?”
The investigators and Dr. Goldenholz have disclosed no relevant financial relationships.
