MRI Study of Antidepressants in the Treatment of Refractory Functional Dyspepsia
Study Details
Study Description
Brief Summary
In this study, diffusion tensor imaging（DTI）technique was used to evaluate the brain microstructures and connective white matter microstructures in patients with refractory FD, resting fMRI was used to evaluate the functional connectivity between hemispheres, and neuroimaging changes after antidepressant intervention were observed to explore the activation patterns of resting brain homeostasis-receptive network areas in patients with refractory FD. We aimed to explore microstructure of white matter and gray matter and functional connectivity between hemispheres to explain the therapeutic mechanism of antidepressants.

Detailed Description
In this study, functional magnetic resonance imaging (fMRI) was used to investigate the abnormal activation patterns of brain regions in patients with refractory FD in resting state, and to observe the changes of brain functions after antidepressant treatment, in order to find scientific evidence for exploring the etiology, neuropathological mechanism and the mechanism of antidepressant treatment of refractory FD.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: refractory FD patients using antidepressants Sixty FD patients who met the criteria were selected as the experimental group after more than two kinds of treatment, including acid-making, proton pump inhibitors (PPI), motivation and anti-Helicobacter pylori（HP） treatment, including 30 in the conventional treatment group and 30 in the combined antidepressant treatment group. |
Drug: selective serotonin reuptake inhibitor (SSRI) or serotonin noradrenaline reuptake inhibitor (SNRI) antidepressants
On the basis of routine treatment for 8-12 weeks, according to the characteristics of symptoms, a combination of SSRI or SNRI antidepressant drugs was given for 12 weeks.
|
| Placebo Comparator: refractory FD patienTS using conventional treatment Sixty FD patients who met the criteria were selected as the experimental group after more than two kinds of treatment, including acid-making, PPI, motivation and anti-HP treatment, including 30 in the conventional treatment group and 30 in the combined antidepressant treatment group. |
Other: conventional therapy
Anti-HP, acid suppression, gastrointestinal motility regulation, etc.
|
| No Intervention: normal control Age, sex and education matched, right-handed 30 normal people. |
Outcome Measures
Primary Outcome Measures
- Nepean Dyspepsia Index [Change from Baseline at 12th week]
Evaluation of digestive tract symptoms
Secondary Outcome Measures
- Zung Self-Rating Anxiety Scale [Change from Baseline at 12th week]
It is a scale measures anxiety level of patients including 20 items, and total score ranges from 20 to 80. Higher values represent a worse outcome.
- Zung Self-Rating Depression Scale [Change from Baseline at 12th week]
It is a scale measures depression level of patients including 20 items, and total score ranges from 20 to 80. Higher values represent a worse outcome.
- The Pittsburgh Sleep Quality Index [Change from Baseline at 12th week]
Assessment of Sleep Status
- quality of life survey questionnaire [Change from Baseline at 12th week]
Assessment of quality of life
- Incidence of Treatment-Emergent Adverse Events [through study completion, an average of 3 years]
Record any adverse events during treatment
- Functional magnetic resonance imaging [baseline and 12th week]
assesses brain microstructures and connective white matter microstructures, and assesses functional connectivity between hemispheres
