The Clinical Characteristics and Related Factors of Centrally Mediated Abdominal Pain Syndrome.

INTRODUCTION: The aim of this study was to explore the clinical characteristics and related factors of centrally mediated abdominal pain syndrome (CAPS). METHODS: Our study included 73 patients with CAPS and 132 age-matched and gender-matched healthy controls. The general information of the participants was collected, and the questionnaires were completed including the 7-item Generalized Anxiety Disorder Scale, 9-item Patient Health Questionnaire, Hamilton Anxiety Scale, Hamilton Depression Scale Pittsburgh Sleep Quality Index, Visual Analog Scale, and Short-Form 36. Univariate and forward stepwise regression analyses were performed to explore the influencing factors of CAPS. RESULTS: Nonexercise (adjusted odds ration [AOR] 4.53; confidence interval [CI] 1.602-12.809), mild-to-moderate depression (AOR 7.931; CI 3.236-19.438), married status (AOR 3.656; CI 1.317-10.418), and drinking coffee (AOR 0.199; CI 0.051-0.775) were found to be related with centrally mediated abdominal syndrome. The Hamilton Anxiety Scale score (7-13) was significantly related to moderate-to-severe abdominal pain (AOR 7.043; CI 1.319-37.593). Higher Hamilton Depression Scale score was related to lower mental component scale score (ß = -0.726, P < 0.01) and physical component scale score (ß = -0.706, P < 0.01). DISCUSSION: Depression, married status, and nonexercise were the independent risk factors of CAPS. Conversely, coffee intake was an independent protective factor of CAPS. Anxiety was related to the severity of abdominal pain, while depression was related to low health-related quality of life.

Acupuncture Improved the Function of the Lower Esophageal Sphincter and Esophageal Motility in Chinese Patients with Refractory Gastroesophageal Reflux Disease Symptoms: A Randomized Trial.

Objectives: Acupuncture is therapeutic for refractory gastroesophageal reflux disease by an unclear mechanism. This study was aimed at investigating the effect of acupuncture on esophageal motility in patients with symptoms of refractory gastroesophageal reflux disease. Methods: Sixty-eight patients with refractory gastroesophageal reflux disease symptoms were prospectively enrolled from August 2014 to December 2018 and randomized into acupuncture and control groups (n = 33 and 35, respectively). The acupuncture group received acupuncture, and the control group received sham acupuncture. Pre- and post-acupuncture high-resolution manometry was performed to evaluate the effect of acupuncture on esophageal motility. The GerdQ questionnaire was used to evaluate the pre- and post-intervention symptoms. Results: After acupuncture, there was a significant increase in the length of lower esophageal sphincter (3.10 ± 1.08 cm vs. 3.78 ± 1.01 cm), length of intra-abdominal lower esophageal sphincter (2.14 ± 1.05 cm vs. 2.75 ± 1.16 cm), and mean basal pressure of lower esophageal sphincter (22.02 ± 10.03 mmHg vs. 25.06 ± 11.48 mmHg) in the acupuncture group (P = 0.014); moreover, the numbers of fragmented contraction and ineffective contraction decreased from 36 to 12 (P < 0.001) and 43 to 18 (P = 0.001), respectively, in the acupuncture group. However, no significant difference was observed in the control group. The GerdQ score decreased significantly from 9.45 ± 2.44 to 7.82 ± 2.21 points in the first week after acupuncture (P < 0.001). Conclusions: Acupuncture, which improves esophageal motility, has short-term efficacy in patients with symptoms of refractory gastroesophageal reflux disease. This trial is registered with Chinese Clinical Trial Registry (ChiCTR1800019646).

Effects of acupuncture on esophageal motility of patients with refractory gastroesophageal reflux disease / 中华消化杂志

Objective To investigate the effects of acupuncture on the improvement of esophageal motility disorder in patients with refractory gastroesophageal reflux disease (GERD).Methods From September 2012 to March 2014,40 patients with refractory GERD were enrolled and evenly divided into the treatment group and the control group. High resolution esophageal impedance manometry was conducted in patients.After the first examination,patients of the control group lay down for 30 minutes, and patients of the treatment group received acupuncture treatment at Neiguan,Gongsun and Zusanli points for 30 minutes.Then all the patients underwent high resolution esophageal impedance manometry again.ManoView ESO 3.0 software was used for analysis.The parameters included swallowing peristalsis defect,lower esophageal sphincter (LES)pressure,LES residual pressure,LES length,upper esophageal sphincter (UES)pressure,distal wave amplitude,peristalsis duration time,starting speed of peristalsis wave,speed of edge contraction and integration of the peristaltic waves.Chi-square test or t test was performed for data analysis.Results The percentage of normal swallows of the treatment group before and after treatment was 56.0% (112/200)and 74.0% (148/200),the percentage of delayed esophageal emptying was 31 .5 % (63/200 )and 11 .5 % (23/200 ),and the differences were statistically significant (χ2 =14.242 and 23.700,both P 0.05 ).The LES resting pressure of the treatment group before and after treatment was (20.2 ±18.8)mmHg (1 mmHg=0.133 kPa)and (26.3±10.1)mmHg,the length of LES was (2.2 ±0.6 )cm and (3.3 ±0.8)cm,the distal esophageal peristaltic amplitude was (60.2 ± 21 .9)mmHg and (41 .1 ± 16.8 )mmHg,and the differences were statistically significant (t = 5 .519, 6.580 and 6.881 ,all P 0.05 ).There as no significant difference in LES resting pressure and LES residual pressure of the control group before and after lying down (both P >0.05 ).However,before and after lying down,there were significant differences in the length of LES ((2.3 ±0.6)cm vs (2.5 ±0.6)cm) and UES resting pressure ((67.4 ±21 .2 )mmHg vs (53.5 ±18.1 )mmHg)in the control group (t =2.530 and 6.652,both P 0.05).Before and after lying down,there was no significant difference in distal wave amplitude,duration of peristalsis,the beginning speed of the peristaltic wave and CFV of the control group (all P >0.05 ).Conclusion Acupuncture can help increase the LES resting pressure,extend the length of LES,improve the overall peristaltic pressure and completeness of esophageal somatic part,meanwhile,it increases the percentage of normal swallows of patients with refractory GERD.
