Effects of Mulberry Leaves on Glycemic Control in Patients With Obesity and Patients With Type 2 Diabetes
Condition: Obesity; Type 2 Diabetes Mellitus
MeSH terms: Diabetes Mellitus; Obesity; Diabetes Mellitus, Type 2
Study type: Interventional

Summary: 
      A 12-week, open-label, randomized, controlled trial investigating effect of mulberry leaves
      plus lifestyle intervention on glycemic control compare with lifestyle intervention alone in
      patients with obesity and patients with type 2 diabetes (T2DM)
    

Detailed description: 
      Diabetes remains a common leading cause of morbidity and mortality among population worldwide
      over decades. Obesity, a crucial risk factors for developing T2DM, commonly exists with
      insulin resistance and impaired beta-cell function. Early management in individuals at high
      risk of T2DM should be therefore considered for preventing or delaying the progression of
      diabetes and diabetic complications.

      Since 1-deoxynojirimycin (DNJ), the major antihyperglycemic compound of mulberry leaves,
      inhibits alpha-glucosidase activities, ingestion of mulberry leaves results in the
      suppression of postprandial hyperglycemia. Long-term effects of mulberry leaves on glycemic
      profiles have been demonstrated in numerous clinical studies; however, the results were
      controversial. In addition, no study was conducted in patients with obesity. As a result,
      this open-label, randomized controlled study aims to investigate efficacy and safety of
      mulberry leaves in combination with lifestyle intervention (diet control) on glycemic control
      in non-diabetic patients with obesity and patients with early-stage T2DM. Efficacy of the
      interventions will be assessed based on the changes in glycemic indexes, expression of
      proteins related to insulin resistance and T2DM, and lipid profiles. Meanwhile, safety will
      be measured by the changes in renal and hepatic enzymes and patient-self reports. The
      outcomes will be monitored at 4-week interval throughout 12 weeks of the study period.
    

Intervention name(s): Mulberry leaves powder; Diet control
Intervention type(s): Dietary Supplement; Behavioral
Intervention description(s): Dried powder of mulberry leaves crude extract containing 12 mg of DNJ will be packed in a sealed packet with light and moisture protection. Participants will be instructed to mix 1 packet of the powder with a half glass (approximately 120 mL) of plain water and ingest thrice daily before meals. Additionally, they will be informed to rinse the glass with more water and drink to ensure that all of the powder will be taken.; Participants will be requested for diet control. They will be asked for attending the diet control program, maintaining diet pattern throughout the study period, and recording a 3-day food record. Individual counseling and assessment of compliance will be performed by licensed dietitians every 4 weeks. Diet control is principally based on carbohydrate counting.
Allocation: Randomized
