Treating to Target
The poster caught the interest of Jeremiah Faith, PhD, who attended the session and was asked to comment. “I think patients want to know what’s happening [with their disease], and we could probably give better care if we know day to day the status of someone, especially because every time we test them we get a point in time, but the reality is probably that people are kind of wavy, and knowing the wave is much better,” he said.
He noted that there was not a strong separation between mean perspiration calprotectin values, but he said the ability to take frequent measurements could overcome that weakness. “The difference between active and remission is not as drastic as what you’d see from blood, for example. But it’s the same thing with your watch. Your watch is a really poor sensor of what your heartbeat is doing, but if you measure it every few seconds, and you average over a long period of time, it can actually more be more [accurate]. So there’s a lot of potential for this,” said Dr. Faith, associate professor of genetics and genomic sciences at the Icahn School of Medicine at Mount Sinai in New York.
If perfected, the device could help efforts at treating to target, in which therapies are adjusted to achieve minimal disease. Currently, physicians are forced to adjust doses or change therapies based on infrequent testing. “If this is accurate ... maybe at some point we will have the tools to be smarter about it,” said Dr. Faith.
