Abstract

Objective: To systematically review the effect of oral intake of bacterial probiotics on 15 variables related to obesity, diabetes and non-alcoholic fatty liver disease. Design: Systematic review and meta-analysis. Data sources: Medline, EMBASE and COCHRANE from 1990 to June 2018. Eligibility criteria: Randomised controlled trials (≥14 days) excluding hypercholesterolaemia, alcoholic liver disease, polycystic ovary syndrome and children <3 years. Results: One hundred and five articles met inclusion criteria, representing 6826 subjects. In overweight but not obese subjects, probiotics induced improvements in: body weight (k=25 trials, d=−0.94 kg mean difference, 95% CI −1.17 to −0.70, I²=0.0%), body mass index (k=32, d=−0.55 kg/m², 95% CI −0.86 to −0.23, I²=91.9%), waist circumference (k=13, d=−1.31 cm, 95% CI −1.79 to −0.83, I²=14.5%), body fat mass (k=11, d=−0.96 kg, 95% CI −1.21 to −0.71, I²=0.0%) and visceral adipose tissue mass (k=5, d=−6.30 cm², 95% CI −9.05 to −3.56, I²=0.0%). In type 2 diabetics, probiotics reduced fasting glucose (k=19, d=−0.66 mmol/L, 95% CI −1.00 to −0.31, I²=27.7%), glycated haemoglobin (k=13, d=−0.28 pp, 95% CI −0.46 to −0.11, I²=54.1%), insulin (k=13, d=−1.66 mU/L, 95% CI −2.70 to −0.61, I²=37.8%) and homeostatic model of insulin resistance (k=10, d=−1.05 pp, 95% CI −1.48 to −0.61, I²=18.2%). In subjects with fatty liver diseases, probiotics reduced alanine (k=12, d=−10.2 U/L, 95% CI −14.3 to −6.0, I²=93.50%) and aspartate aminotransferases (k=10, d=−9.9 U/L, 95% CI −14.1 to -5.8, I²=96.1%). These improvements were mostly observed with bifidobacteria ( Bifidobacterium breve , B. longum ), Streptococcus salivarius subsp . thermophilus and lactobacilli ( Lactobacillus acidophilus , L. casei , L. delbrueckii ) containing mixtures and influenced by trials conducted in one country. Conclusions: The intake of probiotics resulted in minor but consistent improvements in several metabolic risk factors in subjects with metabolic diseases. Trial registration number: CRD42016033273.

  • A meta-analysis showed that B. breve, B. longum, S. thermophilus, L. acidophilus, L. delbrueckii, and L. casei can positively impact anthropometric results and metabolic risk factors, such as fasting glucose, in subjects with metabolic diseases.

    “In another meta-analysis study, it was shown that the probiotic strains B. breve, B. longum, S. thermophilus, L. acidophilus, L. delbrueckii, and L. casei can have a positive impact on anthropometric results and also on the metabolic risk factors (e.g., fasting glucose in individual glucose or insulin) in subjects with metabolic diseases [141].”
  • Probiotic strains from specific taxa (Bifidobacterium breve, B. longum, Streptococcus thermophilus, Lactobacillus acidophilus, L. delbrueckii, and Lacticaseibacillus casei) may positively impact anthropometric outcomes and metabolic risk factors such as fasting glucose or insulin in individuals with metabolic diseases.

    “Interestingly, a meta-analysis showed that probiotic strains from specific taxa (Bifidobacterium breve, B. longum Streptococcus thermophilus Lactobacillus acidophilus, L. delbrueckii, and Lacticaseibacillus casei) may positively impact anthropometric outcomes and metabolic risk factors such as fasting glucose or insulin in individuals with metabolic diseases (Koutnikova et al., 2019).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
