Among secondary endpoints , a significant reduction of maternal insulin ( both in women with or without diabetes ) was observed in the probiotics group .
INTERPRETATION Probiotics during pregnancy do not reduce the incidence of GDM , with a very little ( statistically but not clinical ly significant ) reduction of fasting plasma glucose
AIM To perform a systematic review and meta- analysis of r and omized controlled trials ( RCTs ) to evaluate the effect of  probiotics in pregnancy on the  incidence of gestational diabetes ( GDM ) and fasting plasma glucose ( FPG ) .
The effects of probiotic supplementation on biomarkers of inflammation, oxidative stress and pregnancy outcomes in gestational diabetes
Abstract Objective : This study was design ed to evaluate the effects of probiotic supplementation on biomarkers of inflammation , oxidative stress and pregnancy outcomes  among subjects with gestational diabetes ( GDM ) . Methods : This r and omized , double-blind , placebo-controlled clinical trial was done among 60 subjects with GDM who were not on oral hypoglycemic agents . Patients were r and omly allocated to intake either probiotic capsule containing Lactobacillus acidophilus , Lactobacillus casei and Bifidobacterium bifidum ( 2 × 109 CFU/g each ) ( n = 30 ) or placebo ( n = 30 ) for six weeks . Results : Compared with the placebo , probiotic supplementation result ed in significant decreases in fasting plasma glucose ( FPG ) ( −5.3 ± 6.7 vs. + 0.03 ± 9.0 mg/dL , p = .01 ) , serum high-sensitivity C-reactive protein ( hs-CRP ) ( −2.2 ± 2.7 vs. + 0.5 ± 2.4 μg/mL , p < .001 ) , plasma malondialdehyde ( MDA ) concentrations ( −0.1 ± 0.8 vs. + 0.5 ± 1.5 μmol/L , p = .03 ) and MDA/TAC ratio ( −0.0003 ± 0.0008 vs. + 0.0009 ± 0.002 , p = .004 ) , and a significant increase in total antioxidant capacity ( TAC ) levels ( + 65.4 ± 103.3 vs. −37.2 ± 143.7 mmol/L , p = .002 ) . Probiotic supplementation did not affect pregnancy outcomes . Conclusions : Overall , probiotic supplementation among women with GDM for six weeks had beneficial effects on FPG , serum hs-CRP , plasma TAC , MDA and oxidative stress index , but did not affect pregnancy outcomes
Among secondary endpoints , a significant reduction of maternal insulin ( both in women with or without diabetes ) was observed in the probiotics group .
