What this trial studies

This observational study aims to evaluate the safety and efficacy of washed microbiota transplantation (WMT) in patients with Type 1 Diabetes Mellitus (T1DM). A minimum of 20 participants will be enrolled based on specific inclusion criteria, and their demographic data, blood glucose fluctuations, daily insulin dosages, and clinical outcomes will be monitored. Following the treatment, participants will enter a follow-up period to assess the long-term safety and effectiveness of the intervention.

Why it matters

Potential benefit: If successful, this approach could lead to improved glycemic control and reduced insulin requirements for patients with Type 1 Diabetes.

How similar studies have gone: While the concept of microbiota transplantation is gaining interest, this specific approach for Type 1 Diabetes is relatively novel and has not been extensively tested in previous studies.
