Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A monocentric prospective randomized double-blind controlled study included 90 patients with T2DM on metformin therapy. Patients were randomized into three groups: a metformin group (1000 to 2000 mg daily in two doses), a metformin and probiotic group (metformin + oral probiotic 3x1 capsule), and a metformin, probiotic and UDCA group (metformin + probiotic 3x1 caps + UDCA 3x1 capsule) for four weeks. Two visits were conducted during the study - at the beginning and the end. Visits involved patient interviews, clinical data collection, anthropometric measurements, biochemical analyses and stool sample analysis for the presence of probiotic culture and UDCA.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

The Metformin Group

Group Type OTHER

Metformin Monotherapy

Intervention Type OTHER

Participants in this group (n = 30) received metformin alone, administered in a daily dose of 1000 to 2000 mg divided into two doses, over a period of four weeks.

The Metformin/Probiotic Group

Group Type OTHER

Metformin combined with probiotic (Normia® Jadran Galenski Laboratory) supplementation

Intervention Type OTHER

Participants (n = 30) received metformin (1000-2000 mg/day, divided in two doses) combined with a probiotic supplement (1 capsule three times daily) over a four-week period.

The Metformin/Probiotic/UDCA Group

Group Type OTHER

Triple therapy - metformin, probiotic and ursodeoxycholic acid (Bilexin®, Bosnalijek)

Intervention Type OTHER

Participants in this group (n = 30) were treated with a combination of metformin (1000 - 2000 mg/day), a probiotic (1 capsule three times daily) and ursodeoxycholic acid (UDCA, 1 capsule (250mg) three times daily) for four weeks.
