Brief Summary

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

Adult-onset diabetes is a disease characterized by high blood glucose levels and is one of the leading causes of cardiovascular disease, blindness, end-stage renal failure, and hospitalization. Recent studies support the idea that bacteria found in the gut may play an important role in the development and progression of diabetes. Changes in the gut bacterial environment can affect blood glucose and blood lipids. A increasing number of recent studies have shown that probiotics can alter the gut bacterial environment and reduce blood glucose and blood lipids. The aim of this study is to investigate the effects of probiotics, administered in addition to your current medications, on blood glucose and blood lipids.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants aged 35-65 years diagnosed with T2DM were allocated sequentially according to order of presentation to either probiotic group (n=39) or control group (n=38). The intervention group received a multi-strain probiotic supplement containing Lactobacillus acidophilus, Lactobacillus rhamnosus, Bifidobacterium lactis and Lactobacillus paracasei, twice daily for 12 weeks, while the control group continued standard care. This study evaluated anthropometric measurements, eating attitudes, dietary frequency, quality of life, and physical activity. Biochemical analyses included glycemic control, lipid profiles, inflammation markers (high-sensitivity C-Reactive Protein, Ceruloplasmin), and oxidative stress markers (Malondialdehyde, Glutathione).

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

Participants were allocated sequentially according to order of presentation (alternate allocation). According to the order of presentation to the outpatient clinic, the first patient who met the inclusion criteria was included in the probiotic group and the second patient who presented to the outpatient clinic was included in the control group. Patients in the intervention group were given a probiotic supplement containing Lactobacillus acidophilus, Lactobacillus rhamnosus, Bifidobacterium lactis and Lactobacillus paracasei, each containing 1.25 billion live microorganisms, without vitamins and minerals, twice a day in addition to their current treatment for 12 weeks (Probiotic group). Patients in the control group were not given any additional treatment and were allowed to continue their antidiabetic treatment for 12 weeks (Control group).
