Brief summary
The aim of this study is to assess the beneficial effects of Bifidobacterium Hydrochloride and Berberine on lowering glucose in patients with type 2 diabetes mellitus and to detect the potential mechanism.
Detailed description
Gut microbiota maybe play an important role in patients with type 2 diabetes mellitus (T2DM). Berberine, which is usually used as an antibiotic drug, has been reported a potential glucose-lowering effect in vitro and in vivo studies. Bifidobacterium, as a familiar probiotics, can modulate gut microbiota and improve glucose and lipid metabolism in animal experiments. Therefore, the aim of this study is to assess the beneficial effects of Bifidobacterium Hydrochloride and Berberine on lowering glucose in patients with T2DM and to detect the potential mechanism.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in HbA1c from baseline to week 12 | Baseline and week 12 | Change was measured at baseline and week 12 after randomization. Change was reported as the absolute difference in % HbA1c. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of subjects achieving HbA1c < 7% at week 12 | Week 12 | — |
| Gut microbiome composition | Baseline and week 12 | Faecal bacterial composition determined from microbiological cultures and deep metagenomic next-generation sequencing of bacterial DNA in feces. |
| Changes in postprandial glucagon-like peptide-1 (GLP-1) secretion between baseline and week 12 | Baseline and week 12 | Plasma level of GLP-1 at baseline and week 12 during a 2 hour-meal test. |
| Adverse effects | From baseline to week 12 | Standardized questionaries regarding gastrointestinal function are filled out at each study visit (0, 4, 8 and 12 weeks after randomization) to detect possible adverse effects of antibiotics. In addition, subjects are given a calendar and informed to write down any symptom or illness during the study period. |
