A good alternative
Commenting on the findings, Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, said the data confirm ECT is highly effective for treatment-resistant depression and show that “newcomer” intravenous ketamine also performs “exceptionally well.”
“This is an extremely important study that really establishes the efficacy of ketamine in a very difficult to treat population,” added Dr. McIntyre, who was not involved in the research.
He added that this “rigorous, well-designed study addresses a critical question” about the comparative efficacy of ECT and intravenous ketamine. It also makes “quite a strong statement about the efficacy of ketamine in younger people.”
He cautioned, however, that this study represents the “first data point and, of course, is not the final word on the topic. There are other studies currently still ongoing that are also comparing ECT to IV ketamine and we’ll look forward to seeing the results.”
The fact that 15%-20% of the study patients had psychotic depression is also noteworthy, said Dr. McIntyre.
“We’ve been hesitant to use ketamine in these patients, I think for obvious reasons, but we recently published a paper showing that it is safe and very effective in these patients,” he said.
Having ketamine as a treatment option is important because the majority of patients who could benefit from ECT decline it, often because of the stigma associated with the procedure, which is often portrayed negatively in films and other media.
“I have been recommending ECT almost every day of my professional life and 98 times out of 100 people say: ‘Thanks but no thanks.’ That’s a problem because ECT is so effective,” Dr. McIntyre said.
The study was funded by the Swedish Research Council, Crafoord Foundation, Skåne Regional Council, Königska Foundation, Lions Forskningsfond Skåne, and the OM Perssons donation foundation. Dr. Movahed Rad has received lecturer honoraria from Lundbeck. Dr. McIntyre has received research grant support from the Canadian Institutes of Health Research/Global Alliance for Chronic Diseases/Chinese National Natural Research Foundation and speaker/consultation fees from Lundbeck, Janssen, and other companies. McIntyre is also CEO of AltMed.
