Abstract
Inflammatory bowel disease (IBD) is a chronic, non-specific inflammatory disease of the intestine that can be classified as ulcerative colitis (UC) and Crohn's disease (CD). Currently, the incidence of IBD is still increasing in developing countries. However, current treatments for IBD have limitations and do not fully meet the needs of patients. There is a growing demand for new, safe, and highly effective alternative drugs for IBD patients. Natural products (NPs) are used in drug development and disease treatment because of their broad biological activity, low toxicity, and low side effects. Numerous studies have shown that some NPs have strong therapeutic effects on IBD. In this paper, we first reviewed the pathogenesis of IBD as well as current therapeutic approaches and drugs. Further, we summarized the therapeutic effects of 170 different sources of NPs on IBD and generalized their modes of action and therapeutic effects. Finally, we analyzed the potential mechanisms of NPs for the treatment of IBD. The aim of our review is to provide a systematic and credible summary, thus supporting the research on NPs for the treatment of IBD and providing a theoretical basis for the development and application of NPs in drugs and functional foods.

Resveratrol and resveratrol nano-delivery systems in the treatment of inflammatory bowel disease. J Nutr Biochem 2022; 109:109101. [PMID: 35777588 DOI: 10.1016/j.jnutbio.2022.109101] [Citation(s) in RCA: 27] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 04/04/2022] [Accepted: 06/08/2022] [Indexed: 12/22/2022]
Abstract
Inflammatory bowel disease (IBD) is a chronic disorder associated with the inflammation in the digestive tract. The exact cause of IBD is unknown; nevertheless, in IBD, the homeostasis of key regulatory factors involved in intestinal immunity has been documented to be disrupted. Despite the lack of a viable treatment for IBD, synthetic drugs and monoclonal antibodies are currently used to treat it. However, these treatments have side effects, and the high relapse rate limits their usage. Dietary polyphenols constitute a great variety of compounds and have shown an array of biological properties. Resveratrol is a natural polyphenol found in grapevines and berries. The therapeutic ability of resveratrol against IBD is amply demonstrated in many in vivo studies. Resveratrol can interact with several molecular targets (Nf-kB, SIRT1, mTOR, HIF-1α, miRNAs, and TNF-α) and effectively prevent/ alleviate IBD symptoms with promising results. Although resveratrol has profound anti-inflammatory properties against IBD, its therapeutic employment is limited due to its low water solubility, less chemical stability, less bioavailability, and rapid metabolism in vivo. Hence, resveratrol encapsulation using different carries and its controlled release has become a promising strategy to overcome limitations. Herein, we meticulously review, talk-over the anti-inflammatory effect and mechanisms of resveratrol in IBD. We further provide the latest information on resveratrol formulations and nano-delivery systems used in oral delivery of resveratrol for the treatment of IBD and offer our view on future research on resveratrol in IBD treatment.

Abstract
OBJECTIVES Coltect is a novel dietary supplement containing curcumin, green tea and selenomethionine. Previous reports have suggested that these agents can prevent colorectal cancer (CRC). The present study examined the chemopreventive effect of Coltect alone or combined with 5-aminosalicylic acid (5-ASA) using the 1,2-dimethylhydrazine (DMH) model in rats. METHODS The effect of Coltect was examined on HT-29 CRC cells by growth inhibition assay. Apoptosis was determined by annexin V-FITC/PI staining. Male rats were injected with DMH in vivo and treated with Coltect 150 mg/kg, 5-ASA 50 mg/kg or their combination, by oral gavage. Aberrant crypt foci (ACF) were identified by methylene blue staining. RESULTS HT-29 cells exhibited a dose-dependent response to Coltect. Part of the growth inhibition can be explained by the induction of mild-moderate apoptosis in cancer cells (28%) compared with the untreated cells (10%). In the in vivo model, the average number of ACF was divided into small (1-3 crypts) or large (≥4 crypts). The Coltect compound reduced the number of small and large ACF similarly to 5-ASA (40% reduction). This reduction was amplified by combining the two agents (70% reduction). CONCLUSION Coltect inhibits the growth of colon cancer cells, induces apoptosis and inhibits ACF development. Furthermore, it augments the growth inhibitory effect of 5-ASA in vivo. This may be clinically important since this safe dietary supplement-drug combination can be administered as a chemopreventive regimen for the treatment of CRC.

Abstract
We report the case of a 57-year-old woman with ulcerative colitis since eight years who developed a diffuse interstitial pneumonia linked to mesalazine (oral and enemas). The adverse drug-related effect to mesalazine was strongly suggested regarding improvement upon discontinuation and relapse after reinstitution of mesalazine. To date, after 8 years, the patient has not any respiratory symptom which is another argument for the adverse drug-related effect to mesalazine.

Abstract
Inflammatory bowel disease (IBD) is classically subdivided into ulcerative colitis (UC) and Crohn’s disease (CD). Patients with IBD have increased risk for colorectal cancer. Because the pathogenesis of colorectal carcinoma has not been entirely defined yet and there is no ideal treatment for colon cancer, cancer prevention has become increasingly important in patients with IBD. The two adopted methods to prevent the development of colon cancer in clinical practice include the prophylactic colectomy and colonoscopic surveillance. But patients and physicians seldom accept colectomy as a routine preventive method and most patients do not undergo appropriate colonoscopic surveillance. Chemoprevention refers to the use of natural or synthetic chemical agents to reverse, suppress, or to delay the process of carcinogenesis. Chemoprevention is a particularly useful method in the management of patients at high risk for the development of specific cancers based on inborn genetic susceptibility, the presence of cancer-associated disease, or other known risk factors. Prevention of colorectal cancer by administration of chemopreventive agents is one of the most promising options for IBD patients who are at increased risks of the disease. The chemopreventive efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) against intestinal tumors has been well established. But with reports that NSAIDs aggravated the symptoms of colitis, their sustained use for the purpose of cancer chemoprevention has been relatively contraindicated in IBD patients. Another hopeful candidate chemoprevention drug for IBD patients is 5-aminosalicylic acid (5-ASA), which is well tolerated by most patients and has limited systemic adverse effects, and no gastrointestinal toxicity. 5-ASA lacks the well-known side effects of long-term NSAIDs use. Retrospective correlative studies have suggested that the long-term use of 5-ASA in IBD patients may significantly reduce the risk of development of colorectal cancer. According to the literature, this agent might well satisfy clinical expectations with respect to a safe and effective chemopreventive agent.

Abstract
BACKGROUND It is an accepted fact that non-steroidal anti-inflammatory drugs (NSAIDs) are potent inhibitors of colorectal carcinogenesis. However, the major disadvantages of NSAIDs are gastrointestinal and renal toxicity. We conducted a prospective pilot study on the effects of the safe salicylic acid derivative, mesalazine, on apoptosis and proliferation of tumour cells and on normal tissue in colorectal cancer patients. METHODS Patients with colorectal cancer were asked to take mesalazine enemas for 14 days. Biopsies from malignant and normal tissue were taken prior to and after this treatment. Apoptosis was scored on haematoxylin/eosin-stained tissue sections, and cell proliferation was assessed by the proliferation marker Ki-67. RESULTS Ten out of 14 patients completed the study. The apoptotic score increased significantly in the tumour samples (pre-treatment 14.6 +/- 1.3 vs. post-treatment 19.4 +/- 0.8; P < 0.03). The apoptotic index in the normal mucosa was unchanged (pre-treatment 3.1 +/- 0.4 vs. post-treatment 2.9 +/- 0.3; N.S.). The cell proliferation in malignant tissue, according to the Ki-67 score, was hardly affected by mesalazine (pre-treatment 522 +/- 38 vs. post-treatment 493 +/- 39; N.S.). There was no effect on the Ki-67 index of normal mucosa (pre-treatment 24.2 +/- 2.0 vs. post-treatment 28.3 +/- 2.0; N.S.). CONCLUSIONS This pilot study conducted in patients with colorectal cancer clearly shows that mesalazine selectively induces apoptosis of tumour cells. On the basis of these findings, which need to be confirmed in larger studies, it may be speculated that 5-ASA could be useful in the chemoprevention of colorectal cancer.

Abstract
Advanced and controlled drug delivery systems are important for clinical disease management. In this review the most important new systems which have reached clinical application are highlighted. Microbiologically controlled drug delivery is important for gastrointestinal diseases like ulcerative colitis and distally localized Crohn's disease. In cardiology the more classic controlled release systems have improved patient compliance and decreased side effects. In the treatment of intractable pain the spinal and transdermal route is well documented. In neurology the flattened peak-through levels of antiepileptic drugs and anti Parkinson's drugs represents a more predictable kinetic profile. Tracheal delivery of corticosteroids and sympaticomimetics in asthma and Chronic Obstructive Pulmonary Disease is fully accepted in clinical practice: delivery by this route results in better efficacy and a better safety profile. In gynaecology the delivery of pulsatile hormones (LHRH) is used for pregnancy induction, while transdermal oestrogens are promising in the prevention of osteoporosis. In surgical practice the use of antibiotic impregnated bone cement and antibiotic impregnated biodegradable collagens is well established. To prevent infections intravascular catheters coated with heparin or antibiotics are used. In ophthalmology the Ocusert systems provide a controlled release of different drugs in the eye. Most spectacular is the clinical introduction of the first liposomal drugs; amfotericine B and daunorubicine. Liposomal formulations of these drugs have enhanced activity and decreased toxicity compared to conventional formulations.
