Conclusions Probiotic supplementation significantly reduced serum concentrations of pro-inflammatory cytokines including , hs-CRP , TNF-a , IL-6 , IL-12 , and IL-4 , but it did not influence IL-1B , IL-8 , IFN-g , and IL-17 concentrations .
A significant increase in serum concentrations of IL-10 , as a anti-inflammatory cytokine was also documented after probiotic supplementation
Purpose No study has summarized earlier findings on the effect of probiotic supplementation on  inflammatory biomarkers .
This systematic review and meta- analysis was conducted to systematic ally review the available placebo-controlled clinical trials about the effect of probiotic supplementation  on several inflammatory biomarkers in adults .
Dietary therapy with Lactobacillus GG, bovine colostrum or bovine immune colostrum in patients with juvenile chronic arthritis: Evaluation of effect on gut defence mechanisms
The effect of dietary therapy with a human Lactobacillus strain GG ( ATCC 53103 ) , bovine colostrum , or bovine immune colostrum with specific antibodies against anaerobic intestinal bacteria on gut defence mechanisms were studied in juvenile chronic arthritis . Thirty patients with juvenile chronic arthritis were r and omly allocated to receive a freeze-dried powder of Lactobacillus GG , or bovine colostrum , or bovine immune colostrum , for a two-week period . Immunologic and non-immunologic gut defence mechanisms were indirectly investigated in blood and faecal sample s. In patients receiving Lactobacillus GG , the median ( interquartile range ) frequency of immunoglobulin-secreting cells , determined by enzyme-linked immunospot assay , increased in the IgA class from 1840 ( 690–2530 ) to 3480 ( 1030–13 170)/106 cells ; p=0.02 . Likewise the median ( interquartile range ) frequency of specific antibody-secreting cells against dietary antigens increased during the Lactobacillus GG therapy in the IgM class from 3.8 ( 1.4–5.0 ) to 11.2 (5.0–30.0)/106 cells ; p=0.02 . In addition , Lactobacillus GG therapy decreased the median ( interquartile range ) activity of faecal urease , which has been associated with mucosal tissue damage , from 40.3 ( 21.7–54.3 ) to 28.6 ( 24.5–49.4 ) nmol . min−1 ( mg protein)−1 ; p=0.10 , while , in patients receiving bovine colostrum , faecal urease activity increased ( from 42.2 to 80.6 ; p=0.04 ) . All findings were transient . We suggest that gut defence mechanisms are disturbed in juvenile chronic arthritis and we further suggest that orally administered Lactobacillus GG has a potential to reinforce the mucosal barrier mechanisms in juvenile chronic arthritis
