A single-center retrospective study on epidemiological and Traditional Chinese Medicine syndrome characteristics of 21010 patients with reflux/heartburn symptoms.

objectiveTo provide a basis for the clinical identification of true and false reflux, integrated traditional Chinese and Western medicine, and psychosomatic treatment, we conducted a retrospective study of the etiology and epidemiological and Traditional Chinese Medicine (TCM) syndrome characteristics of patients with reflux/heartburn symptoms.

methodsThe 210 10 patients with reflux/heartburn treated at Tianjin Nankai Hospital from January 1, 2016, to December 31, 2019, were divided into four groups according to their pathogenesis. Sex, age, course of disease, incidence rate, gastroscopy, 24-h pH-impedance, esophageal manometry, Hamilton Anxiety Scale (HAMA) / Hamilton Depression Scale (HAMD) score, 8-week proton pump inhibitor (PPI) treatment effect, and TCM syndrome characteristics were statistically analyzed.

resultsA total of 21010 patients (8864 men and 12146 women), with reflux/heartburn symptoms were screened, including 6284 (29.9%) patients with reflux esophagitis (RE), 10427 (49.6%) patients with non-erosive reflux esophagitis (NERD), 2430 (11.6%) patients with reflux hypersensitivity (RH), and 1870 (8.9%) patients with functional heartburn (FH). The incidence of the disease was higher in women than in men (0.0001). The ranking of the incidence of anxiety and depression in these four groups was FH>RH>NERD>RE ( 0.0001). There were more women than men in the groups with anxiety and more men than women in the groups with depression ( 0.0001), and there was no significant difference in the distribution of anxiety and depression between men and women ( 0.5689). There were significant differences in TCM syndrome characteristics between NERD, RE, and functional esophageal diseases ( 0.01). The highest proportion of functional esophageal disease TCM symptoms was stagnation and phlegm obstruction syndrome (36.16%), and there was no significant difference between RH and FH. The effective rates of PPI treatment at 8 weeks in patients in the RE, NERD, RH, and FH groups were 89%, 72%, 54%, and 0%, respectively. RE was classified into grades A, B, C, and D according to the Los Angeles grading system. The ranking of the incidence of these four grades was A>B>C>D ( 0.0001). The effective rates of PPI treatment at 8 weeks were 91%, 81%, 69%, and 63% in patients with grade A, B, C, and D RE, respectively ( 0.0001). The highest proportion of TCM syndrome types of NERD and RE was the stagnated heat syndrome in the liver and stomach syndrome, 38.99% and 33.90%, respectively.

conclusionReflux/heartburn symptoms are relatively common in middle-aged women, and NERD is the most common etiology, followed by RE, RH, and FH. The most common TCM syndrome characteristics in NERD and RE were stagnated heat syndrome in the liver and stomach syndrome, and stagnation and phlegm obstruction syndrome in functional esophageal diseases. Most patients with reflux/heartburn symptoms also experienced anxiety and depression.
