What’s Going on With Refractory Heartburn?

L Guadagnoli, A Geeraerts et al. Gastroenterol 2023; 165: 848-860. Open Access! Psychological Processes, Not Physiological Parameters, Are Most Important Contributors to Symptom Severity in Patients With Refractory Heartburn/Regurgitation Symptoms

Methods: Consecutive adult patients (n=393) with refractory heartburn/regurgitation symptoms underwent standard 24-hour pH-impedance monitoring and completed questionnaires assessing past and current gastrointestinal and psychological health. Refractory reflux meant that they continued to have symptoms after completing at least 12 weeks of PPI (twice per day) treatment.

Key findings: Psychological symptoms were significantly associated with reflux symptom severity, and physiological reflux variables (eg, number of reflux episodes) were not.

In the discussion, the authors note that ” prior research demonstrates psychological symptoms, including depression, anxiety, and post-traumatic stress, are associated with reflux symptom severity.25, 26, 27 Indeed, psychological processes are believed to impact the brain–gut axis, particularly its central components,28 leading to enhanced esophageal symptom perception and reporting.6,29,30“

My take: Psychological factors (depression, anxiety, post-traumatic stress, and poor sleep) are important factors in refractory reflux and they need to be considered early in the evaluation.

In this article, the writer describes burning pain associated with his diagnosis of eosinophilic esophagitis. This article has some useful information about eosinophilic esophagitis and about lingering symptoms after responding to treatment.

“My new gastroenterologist had a theory to explain the all-consuming pain under my sternum. Sometimes patients develop a hypersensitivity syndrome, she told me. The original insult — in my case, inflammation of some kind — might be long gone, but the nerves that convey pain can become overactive and begin firing at the slightest provocation…Scientists don’t completely understand how antidepressants help pain syndromes, but certain ones seem to impede pain signals in the nervous system…

Doctors are increasingly aware of these kinds of pain syndromes in many disorders, including GERD. The condition, whose primary symptom is known colloquially as heartburn, is pervasive, afflicting an estimated one in five Americans. Some of these patients continue to feel intense pain even after their stomach acid has been reduced with antacids, a malady most likely caused by a hypersensitivity syndrome similar to mine.”
