Functional foods are health promoters and their use is associated with reduced risk of chronic degenerative and non-transmissible diseases. Examples are symbiotic. The association of one (or more) probiotic with a one (or more) prebiotic is called symbiotic, being the prebiotics complementary and probiotics synergistic, thus presenting a multiplicative factor on their individual actions.
To assess the evidences on the benefits of the use of symbiotics in the treatment of clinical and surgical situations.
The headings symbiotic, probiotic and prebiotic were searched in Pubmed/Medline in the last 15 years, and were selected 25 articles, used for database.
The use of symbiotic may promote an increase in the number of bifidobacteria, glycemic control, reduction of blood cholesterol, balancing the intestinal flora which aids in reducing constipation and/or diarrhea, improves intestinal permeability and stimulation of the immune system. Clinical indications for these products has been expanded, in order to maximize the individual's physiological functions to provide greater. So, with the high interest in the clinical and nutritional control of disease, many studies have been conducted demonstrating the effectiveness of using symbiotic in improving and/or preventing various and/or symptoms of gastrointestinal diseases.
Symbiotic behave differently and positively in various pathological situations.
The use of probiotics as adjuvants in the treatment of eating disorders, known as psychobiotics, has already been investigated as a means of modulating the microbiota-gut-brain axis.
This study aimed to assess the effect of probiotic supplementation on binge eating and food addiction in subjects after Roux-en-Y gastric bypass surgery.
This is a randomized, double-blind, placebo-controlled trial involving 101 patients who received probiotic (Lactobacillus acidophilus NCFM and Bifidobacterium lactis Bi-07) or placebo supplements for 90 days after bariatric surgery, starting on the seventh postoperative day. They were evaluated preoperatively (T0) and postoperatively at 90 days (T1) and 1 year (T2) after surgery. The Yale Food Addiction Scale (YFAS) and Binge Eating Scale (BES) were applied to assess food addiction and binge eating, respectively.
Before surgery, one-third of the patients presented with a food addiction and binge eating diagnosis. The number of symptoms of YFAS and the BES score decreased significantly in both groups at T1 compared to T0. However, a significant effect of treatment with probiotics was observed 1 year after surgery (T2). Both the number of symptoms of food addiction and the binge eating score were lower in the probiotic group than in the placebo group (p=0.037 and p=0.030, respectively).
The use of probiotic supplementation for 90 days in the immediate postoperative period may decrease food addiction symptoms and binge eating score up to 1 year after surgery compared to controls.
Non-alcoholic fatty liver disease (NAFLD) is characterized by accumulation of intrahepatic lipid. The use of live microorganisms promotes beneficial effects; however, the use of symbiotic and its role in NAFLD is not yet fully understood.
Verify if the symbiotic administration influences the occurrence and progression of NAFLD in rats, after induction of hepatic steatosis by high calorie diet.
Forty-five rats were divided into four groups: G1 (control); G2 (control+symbiotic); G3 (high calorie+symbiotic) and G4 (high calorie), and euthanized after 60 days of diet. Liver disease was evaluated by biochemical analysis, IL6 measurement and histological assessment.
Symbiotic had influence neither on weight gain, nor on coefficient dietary intake in G3 and G4. G2 had the greatest weight gain, while G1 had the highest coefficient dietary intake between groups. G1 showed higher expression of aspartate aminotransferase than those from G2 (150±35 mg/dl, and 75±5 mg/dl) while G4 showed higher expression of the enzyme compared to G3 (141±9.7 mg/dl to 78±4 mg/dl). Liver histology showed different stages of NAFLD between groups. G4 animals showed increased serum interleukin-6 when compared to G3 (240.58±53.68 mg/dl and 104.0±15.31 mg/dl).
Symbiotic can reduce hepatic aminotransferases and interleukin-6 expression. However, the histology showed that the symbiotic was not able to prevent the severity of NAFLD in rats.
Manipulating intestinal microbiota with probiotics might stimulate skin response. Understanding all stages of the healing process, as well as the gut-skin-healing response can improve the skin healing process.
To evaluate the effect of perioperative oral administration of probiotics on the healing of skin wounds in rats.
Seventy-two Wistar male adult rats were weighed and divided into two groups with 36 each, one control group (supplemented with oral maltodextrin 250 mg/day) and one probiotic group (supplemented with Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001, Lactobacillus acidophilus NCFM® at a dose of 250 mg/day), both given orally daily for 15 days. The two groups were subsequently divided into three subgroups according to the moment of euthanasia: in the 3rd, 7th and 10th postoperative days.
There were no significant changes in weight in both groups. Wound contraction was faster in probiotic group when compared to the controls, resulting in smaller wound area in the 7th postoperative day. As for histological aspects, the overall H&E score was lower in the probiotic group. The probiotic group showed increased fibrosis from 3rd to the 7th postoperative day. The type I collagen production was higher in the probiotic group at the 10th postoperative day, and the type III collagen increased in the 7th.
The perioperative use of orally administrated probiotic was associated with a faster reduction of the wound area in rats probably by reducing the inflammatory phase, accelerating the fibrosis process and the deposition of collagen.
Chronic wounds in patients with Diabetes Mellitus often become incurable due to prolonged and excessive production of inflammatory cytokines. The use of probiotics modifies the intestinal microbiota and modulates inflammatory reactions.
To evaluate the influence of perioperative supplementation with probiotics in the cutaneous healing process in diabetic rats.
Forty-six rats were divided into four groups (C3, P3, C10, P10) according to the treatment (P=probiotic or C=control, both orally administered) and day of euthanasia, 3rd or 10th postoperative days. All rats were induced to Diabetes Mellitus 72 h before starting the experiment with alloxan. Supplementation was initiated five days before the incision and maintained until euthanasia. Scalpel incision was guided by a 2x2 cm mold and the wounds were left to heal per second-intention. The wounds were digitally measured. Collagen densitometry was done with Picrosirius Red staining. Histological parameters were analyzed by staining by H&E.
The contraction of the wound was faster in the P10 group which resulted in a smaller scar area (p=0.011). There was an increase in type I collagen deposition from the 3rd to the 10th postoperative day in the probiotic groups (p=0.016), which did not occur in the control group (p=0.487). The histological analysis showed a better degree of healing in the P10 group (p=0.005), with fewer polymorphonuclear (p<0.001) and more neovessels (p=0.001).
Perioperative supplementation of probiotics stimulates skin wound healing in diabetic rats, possibly due to attenuation of the inflammatory response and increased neovascularization and type I collagen deposition.
