pectins and Intestinal-Diseases

Intestinal mucositis is a common side effect of the chemotherapeutic agent doxorubicin, which is characterized by severe Toll-like receptor (TLR) 2-mediated inflammation. The dietary fiber pectin is shown to prevent this intestinal inflammation through direct inhibition of TLR2 in a microbiota-independent manner. Recent in vitro studies show that inhibition of TLR2 is determined by the number and distribution of methyl-esters of pectins. Therefore, it is hypothesized that the degree of methyl-esterification (DM) and the degree of blockiness (DB) of pectins determine attenuating efficacy on doxorubicin-induced intestinal mucositis.. Four structurally different pectins that differed in DM and DB are tested on inhibitory effects on murine TLR2 in vitro, and on doxorubicin-induced intestinal mucositis in mice. These data demonstrate that low DM pectins or intermediate DM pectins with high DB have the strongest inhibitory impact on murine TLR2-1 and the strongest attenuating effect on TLR2-induced apoptosis and peritonitis. Intermediate DM pectin with a low DB is, however, also effective in preventing the induction of doxorubicin-induced intestinal damage.. These pectin structures with stronger TLR2-inhibiting properties may prevent the development of doxorubicin-induced intestinal damage in patients undergoing chemotherapeutic treatment with doxorubicin.

Recent progress in endoscopic techniques has revealed that non-steroidal anti-inflammatory drugs (NSAIDs) often cause ulcers in the small intestine in humans, but effective therapy is not available at present. In the present study, we investigated the effects of feeding condition and the amount of dietary fiber (DF) in the diet on the formation of gastrointestinal ulcers induced by NSAIDs in dogs. Several types of diets containing various percentages of DF were given to dogs. Indomethacin (1 or 3 mg/kg, p.o.), ketoprofen (2 mg/kg, s.c.), or fulnixin (1 mg/kg, s.c.) was administered once daily at 10 a.m. after a morning meal or without a morning meal (fasted condition) for 3 - 7 days. Gastrointestinal lesions were examined 24 h after the final dose of the drugs. When indomethacin (3 mg/kg) was administered after a morning meal (fed condition) for 7 days, it produced many lesions in the small intestine. However, when it was given in the fasted condition without the morning meal, the lesions were markedly decreased. All the NSAIDs given after feeding of regular dry food containing 6% DF once a day for 3 days produced many lesions in the small intestine. The lesions were decreased or increased in dogs given prescription diets containing low DF (1.1%) and high DF (15.4%), respectively. Furthermore, lesions were not observed in dogs given canned diet containing very low DF (< 0.1%), whereas lesions appeared again in dogs given canned diet supplemented with cellulose (3 or 10%) but not with pectin (10%). These results suggested that both feeding condition and insoluble DF, such as cellulose in the diet, play an important role in the formation of NSAID-induced small intestinal lesions, and that a diet with no or low amounts of DF may decrease gastrointestinal side-effects associated with the use of NSAIDs.

Effectiveness employment of reseach pectin containing drug for enterosoption cause content pectin substances (5-7%), and protein-carbonic complex-balanced and presence such a important immunecorrects, as arginin and glutamic asid, probiotic of metabiotic type establish nutritive support in enteric insufficiency syndrome treatment. There was marked a beneficial effect during using pectin containing drug in the postoperative treatment of intestinal insufficiency, as was confirmed by evaluation of biopsy specimens of gastric mucosa, jejunum and sigmoid colon. Morphologically, it was expressed in chronic inflammation without acute manifestations.

There was marked a beneficial effect during using pectin containing drug in the postoperative treatment of intestinal insufficiency, as was confirmed by evaluation of biopsy specimens of gastric mucosa, jejunum and sigmoid colon. Morphologically, it was expressed in chronic inflammation without acute manifestations. Restoration of the morphological structure of the small intestinal mucosa at 7th day of the usual treatment was observed in 50% of patients but during treatment using a modified pectin containing drug at 80%, ie in 1,6 times more often.

The treatment method of disbios suffered by patients with syndrome of irritated intestines with constipations was under research. The method was based on introduction of sour-milk beverage with addition of beet pectin in a dietary intake. The comparison product was kefir. The following developments were detected against the positive dynamics of clinical symptoms: improvement of microbiocenosis structure, reduction of potentially pathogenic germs, inhibition of pathogenic properties of enterotoxigenic Staphylococcus aureus. Comparison group results showed lower clinical efficiency and poorer effect of dietary treatment on large gut microorganisms, contents of enterotoxigenic S. aureus remained unchanged. Introduction of sour-milk beverage with addition of alimentary fibre in a dietary intake of patients suffering the syndrome of irritated intestines with constipations was found expedient.
