Introduction:
the aetiology and progression of diabetes mellitus is related to the alteration of gut microbiota. It is therefore expected that, restoring gut microbiota will improve metabolic profile in type 2 diabetes mellitus (T2DM) patients. The main objective of the study was to evaluate the effects of add-on probiotics supplementation containing Lactobacillus spp. and Bifidobacterium spp. on metabolic profile in uncontrolled T2DM patients.
Methods:
we undertook a single arm non-randomized clinical trial. Ten T2DM patients received the allocated treatment. The intervention was a daily intake of probiotics supplementation over an eight-week period. We assessed before and after intervention: insulin sensitivity using the hyperinsulinaemiceuglycaemic clamp, insulin secretion using a standardized mixed meal tolerance test, glycated haemoglobin, serum lipid profile and body composition. In addition, clinical tolerance, ALAT level and serum creatinine were assessed at week 0, 4, 8, 10 and 14 for safety purpose.
Results:
results revealed that insulin sensitivity showed a trend towards increase by 18% after intervention, from; 9.1(12.6-8.3) mg/kg/min to 11.3(15.8-9.7) mg/kg/min, p = 0.07. Insulin secretion increased significantly after intervention,
t90: 0.54 [0.93-0.41]µg/L versus 1.59 [2.58-0.53]µg/L, p = 0.021 and t120: 0.49 (0.71-0.28)µg/L versus 1.49 (2.28-0.51)µg/L, p = 0.038. Plasma glucose reduced significantly after intervention; from 6.9 (8.1-4.9)mmol/L before to 5.8 [6.3-4.3]mmol/L after intervention, p < 0.05 at t0 and from 7.6 [9.0-5.9]mmol/L before to 6.2
(7.4-5.3)mmol/L after intervention, p = 0.04 at t30. There was a significant reduction of 25units in HbA1c, from 80.9 (86.0-73.5)mmol/mol to 56.3 (67.2-45.1)mmol/mol, p=0.005.
Total cholesterol and LDL cholesterol were also significantly lower, from 4.2(4.4-3.8)mmol/L to 3.5[3.9-3.3]mmol/L, p = 0.015 and from 2.3 (2.6-2.0)mmol/L to 1.8(2.2-1.6)mmol/L, p = 0.015 respectively.
Conclusion:
the use of probiotics induced a significant improvement in glucose metabolism and insulin secretion with a major HbA1c reduction over an eight-week intervention.
