Link between advanced glycation end products and stomach movement problems in diabetic gastroparesis
Official title: The Role and Mechanism of SphK1/S1P/FOXO1 Axis Regulating KATP Channel Mediated Gastric Smooth Muscle Dysfunction in Diabetes Gastroparesis
Run by Northern Jiangsu People's Hospital · NCT07324785 · Data updated 2026-11-12
This project will see if levels of advanced glycation end products (AGEs) in blood and stomach tissue are linked to stomach movement problems in adults with diabetic gastroparesis.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 to 75 who either have diagnosed diabetes with gastroparesis symptoms and can consent, or are controls aged 18 to 75 with no history of diabetes or gastroparesis symptoms and can consent.
✕Probably not a fit
Patients currently taking prokinetic, anticholinergic, or dopamine drugs that affect gastric motility, with prior gastrointestinal surgery, pregnancy or planning conception, neurological disorders affecting GI function (e.g., Parkinson's), or pyloric outlet obstruction are excluded and unlikely to benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective observational study that collects gastric smooth muscle tissue, serum, and clinical data from adults with diabetic gastroparesis and from control participants without diabetes or gastroparesis symptoms. Researchers will compare symptom scores (Gastroparesis Cardinal Symptom Index) and electrogastrogram results between the two groups. Laboratory analyses will measure AGEs and contractile protein expression in gastric tissue and serum, and statistical tests will examine differences and correlations with clinical measures. The aim is to clarify whether tissue and serum AGE levels are associated with impaired gastric motility in diabetic patients.
Why it matters
Potential benefit: If successful, the study could clarify whether AGEs contribute to impaired gastric motility in diabetic gastroparesis and point to biomarkers or targets for future treatments.
How similar studies have gone: Prior research has linked AGEs to diabetic tissue damage and some gastrointestinal dysfunction, but direct evidence tying AGEs to gastric motility in diabetic gastroparesis is limited, so this approach is relatively novel.
