| Objectives: Anti-inflammatory therapeutic approaches are considered for the management of type
2 diabetes and for the prevention of its complications. There is limited evidence regarding the
effects of prebiotics on inflammation, especially in patients with type 2 diabetes. This trial aims to
examine the effects of oligofructose-enriched inulin on glycemic status, inflammation markers, and
metabolic endotoxemia in female patients.
Methods: Over a period of 8 wk, 52 women with body mass indices of >25 kg/m2 but <35 kg/m2
with type 2 diabetes were randomly assigned to either an intervention group, in which participants
were given oligofructose-enriched inulin (n ¼ 27, consuming 10 g/d of oligofructose-enriched
inulin), or to a control group, in which participants were given maltodextrin (n ¼ 25, consuming
10 g/d of maltodextrin). Fasting plasma glucose, glycosylated hemoglobin, high-sensitivity Creactive
protein, interleukin-6, tumor necrosis factor-a, interferon-g, interleukin-10, and plasma
lipopolysaccharide were measured before and after the intervention. Data were analyzed with the
use of SPSS software version 13. Paired and unpaired Student t tests and analysis of covariance
were used to compare quantitative variables.
Results: Oligofructose-enriched inulin caused a significant decrease in the levels of fasting plasma
glucose (19.2 mg/dL; 9.50%), glycosylated hemoglobin (1.0%; 8.40%), interleukin-6 (1.3 pg/mL;
8.15%), tumor necrosis factor-a (3.0 pg/mL; 19.80%) and plasma lipopolysaccharide (6.0 EU/mL;
21.95%) as compared with maltodextrin (P < 0.05). Decreases in levels of interferon-g (0.3 pg/mL;
16.50%) and high-sensitivity C-reactive protein (3.9 ng/mL; 31.70%) and an increase in the level of
interleukin-10 (0.4 pg/mL, 11.50%) were not significant in the oligofructose-enriched inulin group
as compared with the maltodextrin group.
Conclusions: In women with type 2 diabetes and suboptimal daily dietary fiber intake, oligofructoseenriched
inulin may help to modulate some inflammatory markers. |
