He noted that patients are often unsure whether a new symptom is the beginning of another episode of IBD or something unrelated.
“One of the biggest challenges of having IBD is just the perception of loss of control of the disease and knowing when things are going to happen,” said Dr. Rubin, a professor of medicine and the codirector of the digestive diseases center at the University of Chicago, and the chair of the scientific advisory committee for the Crohn’s & Colitis Foundation. “I often explain to people that using a tool like this would be similar to patients with diabetes checking their blood sugar – getting a feel for what’s actually happening closer to the time that it’s happening, rather than waiting for it to progress. I really think that the general idea of home monitoring is going to be a major advance in our field.”
Although the new study proved the technique’s acceptability and efficacy, it isn’t without pitfalls, according to Dr. Rubin. False positives or negatives are a concern, and other factors might influence the results. For example, proton pump inhibitors can increase FC levels. Another concern is that some patients can become obsessed with their FC levels, and may want to test themselves at any sign of illness. They may develop unrealistic expectations about the impact of medications on their FC levels.
“That’s going to open up a whole dialogue with people, so that we all are on the same page about it. But I think that the benefits of having this far outweigh those potential risks,” said Dr. Rubin.
