Abstract

OBJECTIVE:

To observe the effect of liraglutide (LIRA) in combination of umbilical cord mesenchymal stem cells (hUC-MSCs) in treating type 2 diabetes mellitus.

METHODS:

Eligibility criteria for subjects includes: type 2 diabetes mellitus with more than 10 years duration; having been treated with secretagogues, metformin and insulin in combination with LIRA for at least 6 months; poor glycemic control [glycosylated hemoglobin A1c(HbA1c) 7%-10%]. Totally, twelve patients were enrolled and randomly divided into two groups: the group A (LIRA group, n=6) and the group B (LIRA+ hUC-MSCs group, n=6). The hUC-MSCs were transplanted through infusing of 1×10(6) cells /kg via pancreatic artery directed by interventional radiology on the first day, and followed by infusing 1×10(6) cells /kg through peripheral vein on the eighth, the fifteenth and the twenty-second day sequentially. The control subjects were infused with saline. Both groups were treated with LIRA for 24 weeks at the same period. Fasting plasma glucose(FPG), 2h postprandial plasma glucose(2hPG) and HbA1c were measured. A 75 g oral glucose tolerance test(OGTT)was performed. The early phase of C peptide(CP) secretion function(ΔCP30/ΔG30), the total amount of C peptide secretion function(AUCCP180)and Homeostasis model assessment of insulin resistance (HOMA-IR) were calculated.

RESULTS:

(1) The baseline FPG, 2hPG, HbA1c, ΔCP30/ΔG30, AUCCP180 and HOMA-IR were comparable between the two groups(P>0.05). (2) Compared with subjects in group A, FPG, 2hPG and HbA1c levels were significantly decreased in subjects in group B [(8.33±0.99) mmol/L vs (6.64±0.79)mmol/L, (13.85±0.86) mmol/L vs (8.65±1.12) mmol/L, (7.82±0.31)% vs (6.82±0.53)%, P<0.05]. (3) Compared with group A, ΔCP30/ΔG30 and AUCCP180 were significantly increased, and HOMA-IR was significantly decreased in group B(0.22±0.13 vs 0.70±0.38, 12.52±5.30 vs 21.16±3.17, 9.46±4.88 vs 4.30±2.68, P<0.05).

CONCLUSION:

LIRA treatment in combination with hUC-MSCs improves glucose metabolism and the β cell function in type 2 diabetic patients. (ClinicalTrials.gov NCT01954147).

Abstract

Cellular therapies offer novel opportunities for the treatment of type 2 diabetes mellitus (T2DM). The present study evaluated the long-term efficacy and safety of infusion of Wharton’s jelly-derived mesenchymal stem cells (WJ-MSC) on T2DM. A total of 61 patients with T2DM were randomly divided into two groups on the basis of basal therapy; patients in group I were administered WJ-MSC intravenous infusion twice, with a four-week interval, and patients in group II were treated with normal saline as control. During the 36-month follow-up period, the occurrence of any adverse effects and the results of clinical and laboratory examinations were recorded and evaluated. The lack of acute or chronic adverse effects in group I was consistent with group II.. Blood glucose, glycosylated hemoglobin, C-peptide, homeostasis model assessment of pancreatic islet β-cell function and incidence of diabetic complications in group I were significantly improved, as compared with group II during the 36-month follow-up. The results of the present study demonstrated that infusion of WJ-MSC improved the function of islet β-cells and reduced the incidence of diabetic complications, although the precise mechanisms are yet to be elucidated. The infusion of WJ-MSC may be an effective option for the treatment of patients with type 2 diabetes.

Abstract

Rapidly increasing number of diabetic patients across the world is a great challenge to the current therapeutic approach. Although the traditional method of rendering exogenous insulin is an established method of treatment, it is not sufficient and often causes lethal hypoglycemia. There is also a good amount of success with whole organ transplantation or Islet cells’ transplantation. But this technique is limited with regards the availability of donors. Currently, many clinicians and researchers are involved in clinical studies using various different stem cells from embryonic as well as adult sources for the treatment of diabetes. In this review we have tried to discuss the results of various clinical trials using stem cells. We have also tried to look at various stem cell types and the routes of injections that are currently being followed world wide.
