A systematic review of the efficacy and safety of turmeric in the treatment of digestive disorders. Phytother Res 2024; 38:2687-2706. [PMID: 38503513 PMCID: PMC11168884 DOI: 10.1002/ptr.8189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 02/24/2024] [Accepted: 03/02/2024] [Indexed: 03/21/2024]
Abstract
Turmeric has been gaining popularity as a treatment option for digestive disorders, although a rigorous synthesis of efficacy has not been conducted. This study aimed to summarize the evidence for the efficacy and safety of turmeric in the treatment of digestive disorders, including inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS), dyspepsia, gastroesophageal reflux disease, and peptic ulcers. Literature searches were conducted in Medline, EMBASE, AMED, the Cochrane Central Register of Control Trials, and Dissertation Abstracts from inception to November 15, 2021. Dual independent screening of citations and full texts was conducted and studies meeting inclusion criteria were retained: randomized controlled trials (RCT) and comparative observational studies evaluating turmeric use in people of any age with one of the digestive disorders of interest. Extraction of relevant data and risk of bias assessments were performed by two reviewers independently. Meta-analysis was not conducted due to high heterogeneity. From 1136 citations screened, 26 eligible studies were retained. Most studies were assessed to have a high risk of bias, and many had methodological limitations. Descriptive summaries suggest that turmeric is safe, with possible efficacy in patients with IBD or IBS, but its effects were inconsistent for other conditions. The efficacy of turmeric in digestive disorders remains unclear due to the high risk of bias and methodological limitations of the included studies. Future studies should be designed to include larger sample sizes, use rigorous statistical methods, employ core outcome sets, and adhere to reporting guidance for RCTs of herbal interventions to facilitate more meaningful comparisons and robust conclusions.

Are Internet Information Sources Helpful for Adult Crohn's Disease Patients Regarding Nutritional Advice? J Clin Med 2024; 13:2834. [PMID: 38792376 PMCID: PMC11121864 DOI: 10.3390/jcm13102834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 05/08/2024] [Accepted: 05/10/2024] [Indexed: 05/26/2024] Open
Abstract
Background: Adult patients suffering from Crohn's disease (CD) are often dissatisfied with the information they receive from their physicians about nutrition and its impact on CD inflammation activity. Only a few publications are available about patients' internet research on nutrition in CD. The study aim is to elucidate the internet information sources of adult CD patients regarding nutritional advice via a questionnaire. Methods: A questionnaire with 28 (general and specific) questions for outpatients at our tertiary center with CD was created and used for an analysis of their information sources about nutrition in CD. Four CD and/or nutritional medicine experts examined the 21 most relevant websites referring to nutritional advice for CD patients. Results: One hundred and fifty CD patients reported their Internet research behavior for nutritional advice and their dietary habits. Many CD patients prefer to consult the Internet instead of asking their general practitioner (GP) for nutritional recommendations. Most of the websites providing nutritional advice for CD patients are of very poor quality and cannot be recommended. We found significant correlations between (a) nutritional habits of CD patients, (b) their information sources and several demographic or CD-related factors. There is a lack of websites which provide high-quality, good nutritional advice to CD patients. Conclusions: The majority of the examined websites did not provide sufficient information according to the CD guidelines and nutritional medicine guidelines. A higher quality level of website content (e.g., on social media or on university/center websites) provided by experienced physicians is required to secure trustworthy and reliable nutritional information in CD.

Abstract
Herbal medicines are used by patients with IBD despite limited evidence. We present a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating treatment with herbal medicines in active ulcerative colitis (UC). A search query designed by a library informationist was used to identify potential articles for inclusion. Articles were screened and data were extracted by at least two investigators. Outcomes of interest included clinical response, clinical remission, endoscopic response, endoscopic remission, and safety. We identified 28 RCTs for 18 herbs. In pooled analyses, when compared with placebo, clinical response rates were significantly higher for Indigo naturalis (IN) (RR 3.70, 95% CI 1.97-6.95), but not for Curcuma longa (CL) (RR 1.60, 95% CI 0.99-2.58) or Andrographis paniculata (AP) (RR 0.95, 95% CI 0.71-1.26). There was a significantly higher rate of clinical remission for CL (RR 2.58, 95% CI 1.18-5.63), but not for AP (RR 1.31, 95% CI 0.86-2.01). Higher rates of endoscopic response (RR 1.56, 95% CI 1.08-2.26) and remission (RR 19.37, 95% CI 2.71-138.42) were significant for CL. CL has evidence supporting its use as an adjuvant therapy in active UC. Research with larger scale and well-designed RCTs, manufacturing regulations, and education are needed.

Abstract
A major factor in long-term impairment is stroke. Patients with persistent stroke and severe functional disabilities have few therapy choices. Long noncoding RNAs (lncRNAs) may contribute to the regulation of the pathophysiologic processes of ischemic stroke as shown by altered expression of lncRNAs and microRNA (miRNAs) in blood samples of acute ischemic stroke patients. On the other hand, multipotent mesenchymal stem cells (MSCs) increase neurogenesis, and angiogenesis, dampen neuroinflammation, and boost brain plasticity to improve functional recovery in experimental stroke models. MSCs can be procured from various sources such as the bone marrow, adipose tissue, and peripheral blood. Under the proper circumstances, MSCs can differentiate into a variety of mature cells, including neurons, astrocytes, and oligodendrocytes. Accordingly, the capability of MSCs to exert neuroprotection and also neurogenesis has recently attracted more attention. Nowadays, lncRNAs and miRNAs derived from MSCs have opened new avenues to alleviate stroke symptoms. Accordingly, in this review article, we examined various studies concerning the lncRNAs and miRNAs' role in stroke pathogenesis and delivered an overview of the therapeutic role of MSC-derived miRNAs and lncRNAs in stroke conditions.

Abstract
Curcumin has gained great prominence for the prevention and treatment of inflammatory bowel disease. However, studies have reported the low bioavailability of orally administered curcumin. This work aimed to evaluate the characteristics, stability and effects of a curcumin-carrying nanoemulsion in preventing intestinal damage induced by indomethacin. Nanoemulsions containing curcumin were prepared by spontaneous emulsification method and it was characterized by dynamic light scattering (DLS), zeta potential and the morphology was evaluated by scanning electron microscopy (SEM). Its stability was tested under different conditions of pH, temperature at 0, 7, 14, 21 and 28 days. In animal experimentation, 36 male mice of the Mus musculus lineage (C57BL/6) were used. The intestinal inflammation was evaluated based on macroscopic, histopathological and metagenomic analysis. It was found a stable nanoemulsion with a size of 409.8 nm, polydispersion index (PDI) of 0.132 and zeta potential of -18.8 mV. However, these lost charge in pH2, showing instability in acidic media (p < 0.05). In animal experiments, the nanoemulsion did not significantly improve intestinal inflammation. However, the group treated with curcumin nanoemulsion showed a higher relative abundance of the genus Lactobacillus (p < 0.05). In conclusion, the curcumin nanoemulsion was relevant in the modulation of the intestinal microbiota.

Abstract
Formulating basic food to improve its nutritional profile is one potential method for food innovation. One option in formulating basic food such as bread is to supplement flours with specified amounts of non-bakery raw materials with high nutritional benefits. In the research presented here, we studied the influence of the addition of curcumin and quercetin extracts in amounts of 2.5% and 5% to wheat flour (2.5:97.5; 5:95). The analysis of the rheological properties of dough was carried out using a Mixolab 2. A Rheofermentometer F4 was used to assess the dough's fermentation, and a Volscan was used to evaluate the baking trials. The effect of the extracts on the rheological properties of dough was measured and found to be statistically significant, with curcumin shortening both dough development time and dough stability. Doughs made with greater quantities of extract had a greater tendency to early starch retrogradation, which negatively affects the shelf life of the end products. The addition of extracts did not significantly affect either the ability to form gas during fermentation or its retention, which is important because this gas is prerequisite to forming a final product with the required volume and porosity of crumb. Less favourable results were found on sensory evaluation, wherein the trial bread was significantly worse than the control wheat bread. The panel's decision-making might have been influenced by the atypical colour of the bread made with additives, and in case of a trial bread made with quercetin, by a bitter taste. From the technological point of view, the results confirmed that the composite flours prepared with the addition of extracts of curcumin and quercetin in amounts of 2.5% and 5% can be processed according to standard procedures. The final product will be bread with improved nutritional profile and specific sensory properties, specifically an unconventional and attractive colour.

Traditional Chinese Medicine: A promising strategy to regulate the imbalance of bacterial flora, impaired intestinal barrier and immune function attributed to ulcerative colitis through intestinal microecology. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116879. [PMID: 37419224 DOI: 10.1016/j.jep.2023.116879] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 06/16/2023] [Accepted: 07/04/2023] [Indexed: 07/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Globally, plant materials are widely used as an additional and alternative therapy for the treating of diverse diseases. Ulcerative colitis (UC) is a chronic, recurrent and nonspecific inflammation of the bowel, referred to as "modern intractable disease" according to the World Health Organization. With the continuous development of theoretical research in Traditional Chinese Medicine (TCM) and the advantages of TCM in terms of low side effects, TCM has shown great progress in the research of treating UC. AIM OF THIS REVIEW This review aimed to explore the correlation between intestinal microbiota and UC, summarize research advances in TCM for treating UC, and discuss the mechanism of action of TCM remedies in regulating intestinal microbiota and repairing damaged intestinal barrier, which will provide a theoretical basis for future studies to elucidate the mechanism of TCM remedies based on gut microbiota and provide novel ideas for the clinical treatment of UC. METHODS We have collected and collated relevant articles from different scientific databases in recent years on the use of TCM in treating UC in relation to intestinal microecology. Based on the available studies, the therapeutic effects of TCM are analysed and the correlation between the pathogenesis of UC and intestinal microecology is explored. RESULTS TCM is used to further protect the intestinal epithelium and tight junctions, regulate immunity and intestinal flora by regulating intestinal microecology, thereby achieving the effect of treating UC. Additionally, TCM remedies can effectively increase the abundance of beneficial bacteria that produce short-chain fatty acids, decrease the abundance of pathogenic bacteria, restore the balance of intestinal microbiota, and indirectly alleviate intestinal mucosal immune barrier dysfunction and promote the repair of damaged colorectal mucosa. CONCLUSION Intestinal microbiota is closely related to UC pathogenesis. The alleviation of intestinal dysbiosis can be a potential novel therapeutic strategy for UC. TCM remedies can exert protective and therapeutic effects on UC through various mechanisms. Although intestinal microbiota can aid in the identification of different TCM syndromes types, further studies are needed using modern medical technology. This will improve the clinical therapeutic efficacy of TCM remedies in UC and promote the application of precision medicine.

Abstract
Neurological disorders are a major global challenge, which counts for a substantial slice of disease burden around the globe. In these, the challenging landscape of central nervous system (CNS) diseases, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and neuro-AIDS, demands innovative and novel therapeutic approaches. Curcumin, a versatile natural compound with antioxidant and anti-inflammatory properties, shows great potential as a CNS adjuvant therapy. However, its limited bioavailability and suboptimal permeability to the blood-brain barrier (BBB) hamper the therapeutic efficacy of curcumin. This review explores how nanocarrier facilitates curcumin delivery, which has shown therapeutic efficacy for various non-CNS diseases, for example, cancers, and can also revolutionize the treatment outcomes in patients with CNS diseases. Toward this, intranasal administration of curcumin as a non-invasive CNS drug delivery route can also aid its therapeutic outcomes as an adjuvant therapy for CNS diseases. Intranasal delivery of nanocarriers with curcumin improves the bioavailability of curcumin and its BBB permeability, which is instrumental in promoting its therapeutic potential. Furthermore, curcumin's inhibitory effect on efflux transporters will help to enhance the BBB and cellular permeability of various CNS drugs. The therapeutic potential of curcumin as an adjuvant has the potential to yield synergistic effects with CNS drugs and will help to reduce CNS drug doses and improve their safety profile. Taken together, this approach holds a promise for reshaping CNS disease management by maximizing curcumin's and other drugs' therapeutic benefits.

The IBD-mouse model is established by replacing normal water intake with 2.5% dextran sulfate sodium salt (DSS) aqueous solution, and 50 mg kg-1 of AKBA treatment is administered. The experimental mice are randomly divided into four groups, including control, AKBA , DSS, and DSS + AKBA groups. AKBA therapy conspicuously ameliorates the adverse symptoms caused by DSS in mice and inhibits the reduction of colon length and the rise of disease activity index score. Hematoxylin-eosin staining results suggest that AKBA strikingly improves the pathological conditions of the colon and small intestine tissues in IBD mice. AKBA prominently inhibits the DSS-induced increase of proinflammatory factor contents and the upregulation of the c-Jun N-terminal kinase (JNK)-p38/mitogen-activated protein kinase (MAPK) and Nuclear factor kappa B (NF-κB) pathways' protein levels in the colon tissues of IBD mice. AKBA alleviates DSS-induced colonic inflammatory injury in IBD mice by repressing the activation of the JNK-p38/MAPK and NF-κB pathways.

Abstract
Inflammatory bowel disease (IBD) is a long-term, progressive, and recurrent intestinal inflammatory disorder. The pathogenic mechanisms of IBD are multifaceted and associated with oxidative stress, unbalanced gut microbiota, and aberrant immune response. Indeed, oxidative stress can affect the progression and development of IBD by regulating the homeostasis of the gut microbiota and immune response. Therefore, redox-targeted therapy is a promising treatment option for IBD. Recent evidence has verified that Chinese herbal medicine (CHM)-derived polyphenols, natural antioxidants, are able to maintain redox equilibrium in the intestinal tract to prevent abnormal gut microbiota and radical inflammatory responses. Here, we provide a comprehensive perspective for implementing natural antioxidants as potential IBD candidate medications. In addition, we demonstrate novel technologies and stratagems for promoting the antioxidative properties of CHM-derived polyphenols, including novel delivery systems, chemical modifications, and combination strategies.

Abstract
Evidence-based dietary guidance around dietary fiber in inflammatory bowel disease (IBD) has been limited owing to insufficient reproducibility in intervention trials. However, the pendulum has swung because of our increased understanding of the importance of fibers in maintaining a health-associated microbiome. Preliminary evidence suggests that dietary fiber can alter the gut microbiome, improve IBD symptoms, balance inflammation, and enhance health-related quality of life. Therefore, it is now more vital than ever to examine how fiber could be used as a therapeutic strategy to manage and prevent disease relapse. At present, there is limited knowledge about which fibers are optimal and in what form and quantity they should be consumed to benefit patients with IBD. Additionally, individual microbiomes play a strong role in determining the outcomes and necessitate a more personalized nutritional approach to implementing dietary changes, as dietary fiber may not be as benign as once thought in a dysbiotic microbiome. This review describes dietary fibers and their mechanism of action within the microbiome, details novel fiber sources, including resistant starches and polyphenols, and concludes with potential future directions in fiber research, including the move toward precision nutrition.

Block Copolymer Nanomicelle-Encapsulated Curcumin Attenuates Cerebral Ischemia Injury and Affects Stem Cell Marker Expression by Inhibiting lncRNA GAS5. Stem Cells Int 2023; 2023:9821500. [PMID: 36845969 PMCID: PMC9957624 DOI: 10.1155/2023/9821500] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 10/11/2022] [Accepted: 01/25/2023] [Indexed: 02/19/2023] Open
Abstract
Stroke has become the most common cause of death among residents in China, among which ischemic stroke accounts for the vast majority reaching 70% to 80%. It is of great importance to actively investigate the protective mechanism of cerebral ischemia injury after IS (ischemic stroke). We constructed cerebral ischemia injury models in vivo MACO rat and in vitro (oxygen-glucose deprivation cell model) and set up different interference groups. RT-PCR (reverse transcription PCR) was conducted to detect the expression of lncRNA in neuronal cells, brain tissue, and plasma of different groups, and ELISA (enzyme-linked immunosorbent assay) and western blot were used to detect the expression of the protein in neuronal cells, brain tissue, and plasma of different groups. Cell activity was detected by the CCK-8 assay, while cell apoptosis was examined by TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) assay. In the rats' neuronal cells and brain tissue, curcumin can inhibit the expression of lncRNA GAS5 (long noncoding RNA growth arrest-specific 5). In oxygen-glucose-deprived neuronal cells in vitro, curcumin and low-expressed lncRNA GAS5 can enhance cell activity and decline cell apoptosis, but the addition of curcumin and overexpressed lncRNA GAS5 can make this phenomenon disappear. In neuronal cells, plasma, and brain tissue, curcumin and the low-expressed lncRNA GAS5 can inhibit the expression of IL-1β (interleukin 1 beta), TNF-α (tumor necrosis factor alpha), IL-6 (interleukin 6), Sox2 (SRY-box transcription factor 2), Nanog, and Oct4 (octamer-binding transcription factor 4). However, overexpressed lncRNA GAS5 and curcumin made the inhibitory effect disappear. In conclusion, this study demonstrated that curcumin could inhibit the expression of lncRNA GAS5, thereby inhibiting the expression of inflammation-related factors IL-1β, TNF-α, and IL-6, and ultimately achieve the purpose of attenuating cerebral ischemic cell damage. However, curcumin and lncRNA GAS5 may not alleviate cerebral ischemic cell damage by affecting stem cell differentiation.

Abstract
OBJECTIVES Fraxinus excelsior L. (FE) is traditionally used to treat inflammatory and pain disorders. This study aimed to identify the constituents of FE leaves and evaluate the effects of its n-hexane (FEH), ethyl acetate (FEE), methanol (FEM) extracts and constituents on the viability of THP-1 cells and their ability to release pro-inflammatory cytokines. METHODS THP-1 cell viability was assessed using an MTT assay. The immunomodulatory activity was evaluated by measuring tumour necrosis factor-alpha (TNF-α) and interleukin 12 (IL-12) released by lipopolysaccharide-stimulated THP-1 cells using enzyme-linked immunosorbent assays. KEY FINDINGS Triterpenes, tyrosol esters, alkanes, phytyl and steryl esters, pinocembrin and bis(2-ethylhexyl)phthalate were isolated from FE. The tyrosol esters showed no significant effect on THP-1 cell viability. FEH, FEE, FEM, and pinocembrin, ursolic acid, oleanolic acid had IC50 values of 56.9, 39.9, 124.7 µg/ml and 178.6, 61.5 and 199.8 µM, respectively. FE extracts, ursolic acid, oleanolic acid and pinocembrin significantly reduced TNF-α/IL-12 levels. The tyrosol esters did not significantly affect TNF-α/IL-12 production. CONCLUSIONS FE was able to reduce pro-inflammatory cytokine production indicating a mechanistic focus in its use for inflammation and pain. Further investigations are warranted to unravel the mode of action of the tested constituents and discover other potentially active compounds in FE extracts.

Abstract
Inflammatory bowel diseases (IBD) are chronic relapsing idiopathic inflammatory conditions affecting the gastrointestinal tract. They are mainly represented by two forms, ulcerative colitis (UC) and Crohn's disease (CD). IBD can be associated with the activation of nuclear factors, such as nuclear factor-kB (NF-kB), leading to increased transcription of pro-inflammatory mediators that result in diarrhea, abdominal pain, bleeding, and many extra-intestinal manifestations. Phytochemicals can interfere with many inflammation targets, including NF-kB pathways. Thus, this review aimed to investigate the effects of different phytochemicals in the NF-kB pathways in vitro and in vivo models of IBD. Fifty-six phytochemicals were included in this study, such as curcumin, resveratrol, kaempferol, sesamol, pinocembrin, astragalin, oxyberberine, berberine hydrochloride, botulin, taxifolin, naringin, thymol, isobavachalcone, lancemaside A, aesculin, tetrandrine, Ginsenoside Rk3, mangiferin, diosgenin, theanine, tryptanthrin, lycopene, gyngerol, alantolactone, mangostin, ophiopogonin D, fisetin, sinomenine, piperine, oxymatrine, euphol, artesunate, galangin, and nobiletin. The main observed effects related to NF-kB pathways were reductions in tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-6, interferon-gamma (IFN-γ), and cyclooxygenase-2 (COX-2), and augmented occludin, claudin-1, zonula occludens-1, and IL-10 expression levels. Moreover, phytochemicals can improve weight loss, stool consistency, and rectal bleeding in IBD. Therefore, phytochemicals can constitute a powerful treatment option for IBD in humans.

Abstract
The correlation of bile acid (BA) metabolism disorder with the pathogenesis of ulcerative colitis (UC) is realized nowadays. Farnesoid X receptor (FXR), a controller for BA homeostasis and inflammation, is a promising target for UC therapy. Nigakinone has potential therapeutic effects on colitis. Herein, we investigated the anti-UC effects and mechanism of nigakinone in colitic animals induced by dextran sulfate sodium (DSS). The related targets involved in the nucleotide-binding oligomerization domain, leucine-rich repeat, and pyrin domain-containing 3 (NLRP3) signaling pathway were measured. BA-targeted metabolomics was employed to reveal the regulatory effects of nigakinone on BA profile in colitis, while expressions of FXR and its mediated targets referring to BA enterohepatic circulation were determined. The critical role of FXR in the treatment of nigakinone for colitis was studied via molecule-docking, dual-luciferase reporter® (DLR™) assays, FXR silencing cells, and FXR knockout mice. Results showed nigakinone attenuated DSS-induced colitis symptoms, including excessive inflammatory response by NLRP3 activation, and injury of the intestinal mucosal barrier. Nigakinone regulated BA disorders by controlling cholesterol hydroxylase and transporters mediated by FXR, then decreased BA accumulation in colon. Molecular-docking and DLR™ assays indicated FXR might be a target of nigakinone. In vitro, nigakinone restrained BA-induced inflammation and cell damage via FXR activation and inhibition of inflammatory cytokines. However, ameliorating effects of nigakinone on colitis were suppressed by FXR knockout or silencing in vivo or in vitro. Taken together, nigakinone ameliorated experimental colitis via regulating BA profile and FXR/NLRP3 signaling pathway.

Abstract
Ulcerative colitis (UC) is one of the inflammatory bowel diseases (IBD). It is a chronic autoimmune inflammation of unclear etiology affecting the colon and rectum, characterized by unpredictable exacerbation and remission phases. Conventional treatment options for UC include mesalamine, glucocorticoids, immunosuppressants, and biologics. The management of UC is challenging, and other therapeutic options are constantly being sought. In recent years more attention is being paid to curcumin, a main active polyphenol found in the turmeric root, which has numerous beneficial effects in the human body, including anti-inflammatory, anticarcinogenic, and antioxidative properties targeting several cellular pathways and making an impact on intestinal microbiota. This review will summarize the current knowledge on the role of curcumin in the UC therapy.

Micellar Curcumin: Pharmacokinetics and Effects on Inflammation Markers and PCSK-9 Concentrations in Healthy Subjects in a Double-Blind, Randomized, Active-Controlled, Crossover Trial. Mol Nutr Food Res 2022; 66:e2200139.

Abstract
SCOPE Preclinical models have demonstrated the anti-inflammatory and lipid-lowering effects of curcumin. Innovative formulations have been developed to overcome the poor bioavailability of native curcumin. The study hypothesizes that the bioavailability of micellar curcumin is superior to native curcumin and investigates the potential anti-inflammatory and proprotein convertase subtilisin/kexin type 9 (PCSK9) concentration lowering effects. METHODS AND RESULTS In this double-blind, randomized, crossover trial, 15 healthy volunteers receive micellar or native curcumin (105 mg day-1 ) for 7 days with a ≥7 days washout period. Curcumin and metabolite concentrations are quantified by high-performance liquid chromatography with fluorescence detection (HPLC-FD), and pharmacokinetics are calculated. To analyze anti-inflammatory effects, blood samples (baseline, 2 h, 7 days) are stimulated with 50 ng mL-1 lipopolysaccharides (LPS). Interleukin (IL)-6, tumor-necrosis factor (TNF-α), and PCSK9 concentrations are quantified. Micellar curcumin demonstrates improved bioavailability (≈39-fold higher maximum concentrations, ≈14-fold higher area-under-the-time-concentration curve, p < 0.001) but does not reduce pro-inflammatory cytokines in the chosen model. Subjects receiving micellar curcumin have significantly lower PCSK9 concentrations (≈10% reduction) after 7 days compared to baseline (p = 0.038). CONCLUSION Micellar curcumin demonstrates an improved oral bioavailability but does not show anti-inflammatory effects in this model. Potential effects on PCSK9 concentrations warrant further investigation.

Tackling Inflammatory Bowel Diseases: Targeting Proinflammatory Cytokines and Lymphocyte Homing. Pharmaceuticals (Basel) 2022; 15:ph15091080. [PMID: 36145301 PMCID: PMC9502105 DOI: 10.3390/ph15091080] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 08/23/2022] [Accepted: 08/26/2022] [Indexed: 11/21/2022] Open
Abstract
Inflammatory bowel diseases (IBDs) are characterized by chronic inflammatory disorders that are a result of an abnormal immune response mediated by a cytokine storm and immune cell infiltration. Proinflammatory cytokine therapeutic agents, represented by TNF inhibitors, have developed rapidly over recent years and are promising options for treating IBD. Antagonizing interleukins, interferons, and Janus kinases have demonstrated their respective advantages in clinical trials and are candidates for anti-TNF therapeutic failure. Furthermore, the blockade of lymphocyte homing contributes to the excessive immune response in colitis and ameliorates inflammation and tissue damage. Factors such as integrins, selectins, and chemokines jointly coordinate the accumulation of immune cells in inflammatory regions. This review assembles the major targets and agents currently targeting proinflammatory cytokines and lymphatic trafficking to facilitate subsequent drug development.

Abstract
Autoimmune diseases usually arise as a result of an aberrant immune system attack on normal tissues of the body, which leads to a cascade of inflammatory reactions. The immune system employs different types of protective and anti-inflammatory cells for the regulation of this process. Curcumin is a known natural anti-inflammatory agent that inhibits pathological autoimmune processes by regulating inflammatory cytokines and their associated signaling pathways in immune cells. Due to the unstable nature of curcumin and its susceptibility to either degradation, or metabolism into other chemical entities (i.e., metabolites), encapsulation of this agent into various nanocarriers would appear to be an appropriate strategy for attaining greater beneficial effects from curcumin as it pertains to immunomodulation. Many studies have focused on the design and development of curcumin nanodelivery systems (micelles, dendrimers, and diverse nanocarriers) and are summarized in this review in order to obtain greater insight into novel drug delivery systems for curcumin and their suitability for the management of autoimmune diseases.

Abstract
This umbrella review is to recapitulate and grade the available evidence of associations between consumption of Zingiberaceae plants/curcumin (Cur) and multiple health-related outcomes. This study included 161 meta-analyses of randomized controlled trials in 76 articles with 67 unique health outcomes. Data on heterogeneity and publication bias are considered to assess the quality of evidence. Based on the different impact of Zingiberaceae plants/Cur on human health, the advantages outweigh the disadvantages. Zingiberaceae plants/Cur can mainly improve metabolic syndrome, non-alcoholic fatty liver disease, cardiovascular disease, and some chronic inflammatory diseases, likewise, obviously relief the pain of osteoarthritis and related diseases. Ginger supplements have been shown to improve vomiting during pregnancy and to relieve nausea and vomiting caused by chemotherapy and surgery. The surgery is any type of surgery, including laparoscopic surgery, gynecological surgery and mixed surgery. Beneficial associations were found with Cur intervention in gastrointestinal, neurological and oral diseases. Zingiberaceae plants/Cur are generally safe and favorable for multiple health outcomes in humans. High-quality research is further needed to prove the observed associations.

Abstract
Phenolic compounds (PCs) present in foods are associated with a decreased risk of developing inflammatory diseases. The aim of this study was to extract and characterize PCs from craft beer powder and evaluate their potential benefits in an experimental model of inflammatory bowel disease (IBD). PCs were extracted and quantified from pure beer samples. BALB/c mice received either the beer phenolic extract (BPE) or beer powder fortified with phenolic extract (BPFPE) of PCs daily for 20 days by gavage. Colon samples were collected for histopathological and immunohistochemical analyses. Dextran sodium sulfate (DSS)-induced mice lost more weight, had reduced colon length, and developed more inflammatory changes compared with DSS-induced mice treated with either BPE or BPFPE. In addition, in DSS-induced mice, the densities of CD4- and CD11b-positive cells, apoptotic rates, and activation of NF-κB and p-ERK1/2 MAPK intracellular signaling pathways were higher in those treated with BPE and BPFPE than in those not treated. Pretreatment with the phenolic extract and BPFPE remarkably attenuated DSS-induced colitis. The protective effect of PCs supports further investigation and development of therapies for human IBD.

Abstract
Objective: Due to its well-known anti-inflammatory property, oxymatrine (OMT) has received more attention on the aspect of treating ulcerative colitis. Although efforts have been undertaken to understand the therapeutic mechanism of OMT on ulcerative colitis (UC), the remedial principle is still ambiguous. Numerous studies have shown that TLR9/Myd88/NF-κB signal pathway played a key role in the pathogenesis of UC. Moreover, TLR9/Myd88/NF-κB signal pathway is a part of the most important pathways for regulating the immune response.Methods: We explored the influence of OMT with different dosages on UC by establishing a 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis model. Moreover, the participation of TLR9/Myd88/NF-κB signal pathway and whether OMT protects against UC though targeting this pathway are further studied.Results: Our data revealed that OMT could significantly relieve the symptom of TNBS-induced colitis in rats by reactivating the tight junction protein and, more important, by inhibiting the activation of TLR9/Myd88/NF-κB pathway and protein expression levels of its downstream inflammatory factors.Conclusion: OMT could relieve colitis in rat models by impacting tight junction proteins' TLR9/Myd88/NF-κB signal pathways and activity.

Considerations to Be Taken When Carrying Out Medicinal Plant Research-What We Learn from an Insight into the IC 50 Values, Bioavailability and Clinical Efficacy of Exemplary Anti-Inflammatory Herbal Components. Pharmaceuticals (Basel) 2021; 14:437.

Abstract
Medicinal plants represent a big reservoir for discovering new drugs against all kinds of diseases including inflammation. In spite the large number of promising anti-inflammatory plant extracts and isolated components, research on medicinal plants proves to be very difficult. Based on that background this review aims to provide a summarized insight into the hitherto known pharmacologically active concentrations, bioavailability, and clinical efficacy of boswellic acids, curcumin, quercetin and resveratrol. These examples have in common that the achieved plasma concentrations were found to be often far below the determined IC50 values in vitro. On the other hand demonstrated therapeutic effects suggest a necessity of rethinking our pharmacokinetic understanding. In this light this review discusses the value of plasma levels as pharmacokinetic surrogates in comparison to the more informative value of tissue concentrations. Furthermore the need for new methodological approaches is addressed like the application of combinatorial approaches for identifying and pharmacokinetic investigations of active multi-components. Also the physiological relevance of exemplary in vitro assays and absorption studies in cell-line based models is discussed. All these topics should be ideally considered to avoid inaccurate predictions for the efficacy of herbal components in vivo and to unlock the "black box" of herbal mixtures.

Abstract
Intestinal inflammation frequently occurs alongside dysmotility, which is characterized by altered myosin light chain phosphorylation levels. Curcumin, an active component from the ginger family, is reported to confer anti‑inflammatory effects. However, the effects of curcumin on both diarrhea and constipation associated inflammation remains to be elucidated. The present study was designed to investigate the effects of curcumin on diarrhea and constipation and to determine the related mechanisms. Sprague‑Dawley rats were used to establish diarrhea and constipation models via intracolonic acetic acid (4%) instillation or cold water gavage for 2 weeks, respectively. Blood samples were collected to measure the serum levels of the cytokines TNF‑α and IL‑1β using ELISA kits. Western blotting was performed to measure NF‑κB, RhoA, Rho‑related kinase 2, phosphorylated MLC20, phosphorylated myosin phosphorylated target subunit 1, 130k Da‑MLC kinase (MLCK), c‑kit tyrosine kinase protein expression, and reverse transcription‑quantitative PCR was conducted to measure MLCK expression levels. The results indicated that curcumin reversed the elevations in the pro‑inflammatory cytokines IL‑1β and TNF‑α by inhibiting the NF‑κB pathway in rats with diarrhea and constipation. The results also indicated that myosin light chain (MLC) phosphorylation in intestinal smooth muscle was positively and negatively associated with the motility of inflammation‑related diarrhea and constipation in rats, respectively. Curcumin significantly reversed the increased MLC phosphorylation in the jejunum of the rats with diarrhea, significantly enhanced the reductions in inflammatory mediators, including TNF‑α and IL‑1β, of rats with constipation and significantly ameliorated the related hyper‑motility and hypo‑motility in rats with both diarrhea and constipation. In conclusion, the potential roles of the MLC kinase, c‑kit tyrosine and Rho A/Rho‑associated kinase 2 pathways, which are involved in curcumin‑induced amelioration of inflammation‑related diarrhea and constipation, were explored in the present study. Results from the present study suggested that curcumin has potential therapeutic value for treating intestinal inflammation and inflammation‑related motility disorders.

Abstract
Polyphenols (PPs) are the naturally occurring bioactive components in fruits and vegetables, and they are the most abundant antioxidant in the human diet. Studies are suggesting that ingestion of PPs might be helpful to ameliorate metabolic syndromes that may contribute in the prevention of several chronic disorders like diabetes, obesity, hypertension, and colon cancer. PPs have structural diversity which impacts their bioavailability as they accumulate in the large intestine and are extensively metabolized through gut microbiota (GM). Intestinal microbiota transforms PPs into their metabolites to make them bioactive. Interestingly, not only GM act on PPs to metabolize them but PPs also modulate the composition of GM. Thus, change in GM from pathogenic to beneficial ones may be helpful to ameliorate gut health and associated diseases. However, to overcome the low bioavailability of PPs, various approaches have been developed to improve their solubility and transportation through the gut. In this review, we present evidence supporting the structural changes that occur after metabolic reactions in PPs (curcumin, quercetin, and catechins) and their effect on GM composition that leads to improving overall gut health and helping to ameliorate metabolic disorders.
