Abstract
INTRODUCTION Functional dyspepsia (FD) is one of the most prevalent chronic disorders affecting up to 30% of the world population with considerable impairment of quality of life. This study evaluated the efficacy of the herbal preparation of Bunium persicum (Boiss.) B.Fedtsch. and Coriandrum sativum L. on symptom severity, symptom frequency, and quality of life of patients with FD. METHODS This double-blind randomized controlled clinical trial, with parallel groups allocation ratio of 1:1, was conducted in a referral clinic of Afzalipour Hospital affiliated with Kerman University of Medical Sciences in Kerman, southeastern Iran. A total of 90 patients with FD (diagnosed based on the Rome IV criteria) were included in this study. The patients with complications during the intervention, pregnancy or lactation, a history of allergy to herbal drugs, use of other medication that affect the symptoms of FD during the study, and severe organic or psychiatric disorders were excluded. The participants received one capsule containing 500 mg of herbal preparation or placebo twice a day for 4 weeks and were subsequently followed up for 4 more weeks. Clinical outcomes were assessed via the Dyspepsia Severity Questionnaire, the Rome IV Diagnostic Questionnaire, and Nepean Dyspepsia Index Questionnaire. RESULTS A total 40 participants in each group completed the follow-up period, and their data were analyzed statistically. All clinical outcomes showed significant improvements by herbal preparation compared to the placebo without serious side effects (p < 0.05). CONCLUSIONS This herbal preparation can significantly improve the quality of life, and symptoms of FD compared to placebo.

Abstract
BACKGROUND One-third of people with gastrointestinal disorders, including functional dyspepsia, use some form of complementary and alternative medicine, including herbal medicines. OBJECTIVES The primary objective is to assess the effects of non-Chinese herbal medicines for the treatment of people with functional dyspepsia. SEARCH METHODS We searched the following electronic databases on 22 December 2022: Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Allied and Complementary Medicine Database, Latin American and Caribbean Health Sciences Literature, among other sources, without placing language restrictions. SELECTION CRITERIA We included RCTs comparing non-Chinese herbal medicines versus placebo or other treatments in people with functional dyspepsia. DATA COLLECTION AND ANALYSIS Two review authors independently screened references, extracted data and assessed the risk of bias from trial reports. We used a random-effects model to calculate risk ratios (RRs) and mean differences (MDs). We created effect direction plots when meta-analysis was not possible, following the reporting guideline for Synthesis without Meta-analysis (SWiM). We used GRADE to assess the certainty of the evidence (CoE) for all outcomes. MAIN RESULTS We included 41 trials with 4477 participants that assessed 27 herbal medicines. This review evaluated global symptoms of functional dyspepsia, adverse events and quality of life; however, some studies did not report these outcomes. STW5 (Iberogast) may moderately improve global symptoms of dyspepsia compared with placebo at 28 to 56 days; however, the evidence is very uncertain (MD -2.64, 95% CI -4.39 to -0.90; I2 = 87%; 5 studies, 814 participants; very low CoE). STW5 may also increase the improvement rate compared to placebo at four to eight weeks' follow-up (RR 1.55, 95% CI 0.98 to 2.47; 2 studies, 324 participants; low CoE). There was little to no difference in adverse events for STW5 compared to placebo (RR 0.92, 95% CI 0.52 to 1.64; I2 = 0%; 4 studies, 786 participants; low CoE). STW5 may cause little to no difference in quality of life compared to placebo (no numerical data available, low CoE). Peppermint and caraway oil probably result in a large improvement in global symptoms of dyspepsia compared to placebo at four weeks (SMD -0.87, 95% CI -1.15 to -0.58; I2 = 0%; 2 studies, 210 participants; moderate CoE) and increase the improvement rate of global symptoms of dyspepsia (RR 1.53, 95% CI 1.30 to 1.81; I2 = 0%; 3 studies, 305 participants; moderate CoE). There may be little to no difference in the rate of adverse events between this intervention and placebo (RR 1.56, 95% CI 0.69 to 3.53; I2 = 47%; 3 studies, 305 participants; low CoE). The intervention probably improves the quality of life (measured on the Nepean Dyspepsia Index) (MD -131.40, 95% CI -193.76 to -69.04; 1 study, 99 participants; moderate CoE). Curcuma longa probably results in a moderate improvement global symptoms of dyspepsia compared to placebo at four weeks (MD -3.33, 95% CI -5.84 to -0.81; I2 = 50%; 2 studies, 110 participants; moderate CoE) and may increase the improvement rate (RR 1.50, 95% CI 1.06 to 2.11; 1 study, 76 participants; low CoE). There is probably little to no difference in the rate of adverse events between this intervention and placebo (RR 1.26, 95% CI 0.51 to 3.08; 1 study, 89 participants; moderate CoE). The intervention probably improves the quality of life, measured on the EQ-5D (MD 0.05, 95% CI 0.01 to 0.09; 1 study, 89 participants; moderate CoE). We found evidence that the following herbal medicines may improve symptoms of dyspepsia compared to placebo: Lafonesia pacari (RR 1.52, 95% CI 1.08 to 2.14; 1 study, 97 participants; moderate CoE), Nigella sativa (SMD -1.59, 95% CI -2.13 to -1.05; 1 study, 70 participants; high CoE), artichoke (SMD -0.34, 95% CI -0.59 to -0.09; 1 study, 244 participants; low CoE), Boensenbergia rotunda (SMD -2.22, 95% CI -2.62 to -1.83; 1 study, 160 participants; low CoE), Pistacia lenticus (SMD -0.33, 95% CI -0.66 to -0.01; 1 study, 148 participants; low CoE), Enteroplant (SMD -1.09, 95% CI -1.40 to -0.77; 1 study, 198 participants; low CoE), Ferula asafoetida (SMD -1.51, 95% CI -2.20 to -0.83; 1 study, 43 participants; low CoE), ginger and artichoke (RR 1.64, 95% CI 1.27 to 2.13; 1 study, 126 participants; low CoE), Glycyrrhiza glaba (SMD -1.86, 95% CI -2.54 to -1.19; 1 study, 50 participants; moderate CoE), OLNP-06 (RR 3.80, 95% CI 1.70 to 8.51; 1 study, 48 participants; low CoE), red pepper (SMD -1.07, 95% CI -1.89 to -0.26; 1 study, 27 participants; low CoE), Cuadrania tricuspidata (SMD -1.19, 95% CI -1.66 to -0.72; 1 study, 83 participants; low CoE), jollab (SMD -1.22, 95% CI -1.59 to -0.85; 1 study, 133 participants; low CoE), Pimpinella anisum (SMD -2.30, 95% CI -2.79 to -1.80; 1 study, 107 participants; low CoE). The following may provide little to no difference compared to placebo: Mentha pulegium (SMD -0.38, 95% CI -0.78 to 0.02; 1 study, 100 participants; moderate CoE) and cinnamon oil (SMD 0.38, 95% CI -0.17 to 0.94; 1 study, 51 participants; low CoE); moreover, Mentha longifolia may increase dyspeptic symptoms (SMD 0.46, 95% CI 0.04 to 0.88; 1 study, 88 participants; low CoE). Almost all the studies reported little to no difference in the rate of adverse events compared to placebo except for red pepper, which may result in a higher risk of adverse events compared to placebo (RR 4.31, 95% CI 1.56 to 11.89; 1 study, 27 participants; low CoE). With respect to the quality of life, most studies did not report this outcome. When compared to other interventions, essential oils may improve global symptoms of dyspepsia compared to omeprazole. Peppermint oil/caraway oil, STW5, Nigella sativa and Curcuma longa may provide little to no benefit compared to other treatments. AUTHORS' CONCLUSIONS Based on moderate to very low-certainty evidence, we identified some herbal medicines that may be effective in improving symptoms of dyspepsia. Moreover, these interventions may not be associated with important adverse events. More high-quality trials are needed on herbal medicines, especially including participants with common gastrointestinal comorbidities.

Abstract
OBJECTIVE This double-blind, placebo-controlled, clinical trial was conducted to define the effects of Nigella sativa (N. Sativa) powder plus conventional medical treatment of Helicobacter pylori (H. pylori) on serum ghrelin level and appetite in H. pylori-infected patients. METHODS In the present study, 51 H. pylori-positive patients were randomly allocated to treatment (n = 26) or placebo (n = 25) groups. They received 2 g/day N. Sativa with quadruple therapy or 2 g/day placebo plus quadruple therapy for 8 weeks. The serum level of ghrelin was assessed before and after the intervention. Appetite was evaluated at the onset and at the end of the intervention. RESULTS At the end of the study, the appetite of the treatment group improved significantly compared with the placebo group (P = 0.02). Statistically, the difference in serum ghrelin levels between the study's groups was insignificant (P > 0.05). CONCLUSION Supplementation with N. Sativa powder may be a beneficial adjunctive therapy in H. pylori-infected patients.

IRANIAN JOURNAL OF PHARMACEUTICAL RESEARCH 2022; 21:e127030. [PMID: 36060908 PMCID: PMC9420233 DOI: 10.5812/ijpr-127030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/27/2022] [Accepted: 04/11/2022] [Indexed: 11/16/2022]
Abstract
Antibiotic-resistant Helicobacter pylori isolates have become a global concern. The standard triple or quadruple therapies have recently become the most effective protocol for eradicating H. pylori in the gastrointestinal tract. There is evidence regarding the impact of different complementary or dietary supplements on H. pylori eradication. This review article intended to search electronic bibliographic databases for any clinical studies that evaluated the use of any herbal or dietary supplements to eradicate H. pylori up to June 2021. A total of 20 human studies met our criteria and were reviewed. Although some herbal medicines have shown their efficacy and safety in eradicating H. pylori in different clinical trials, more randomized blind, placebo-controlled human trials with a large sample size must be performed to extend our knowledge.

Abstract
Abstract:
Gastrointestinal (GI) disorders are the ailments of the digestive tract that affect its function like digestion, absorption and excretion. The dysfunction of the gastrointestinal tract may occur due to infections by bacteria, parasites and viruses. Peptic Ulcer Disease is a gastrointestinal tract disorder of stomach and duodenum that is associated with infection of Helicobacter pylori. Helicobacter pylori is regarded as the worldwide causative agent responsible for the etiology of peptic ulcer and gastric carcinoma. The existing drug therapies are good healers in this situation, but due to resistance problems and side effects of drugs, researchers have been working to find out some safe alternatives. Interestingly, the medicinal herbs have been used for treating several disorders, including peptic ulcers and are considered an effective and safer alternative to existing drugs. It is also considered as an eco-friendly, easily available, safe, and less toxic traditional treatment therapy. The combination of herbal medicines with natural products has been shown effective in treating peptic ulcers. In this review, the medicinal plants used against H. pylori infection have been discussed. The mechanism of herbal drugs in healing peptic ulcers by inhibition of H+ K+ ATPase pump, secretion of gastric acid and gastric mucosal protection have also elaborated. The phytochemicals responsible for biological activity have been summarized in the present article. The combination of herbs and natural products in the form of the polyherbal formulation may also be helpful as an effective therapy for treating peptic ulcers. Medicinal plants may offer the researchers new chemical molecules to explore as future drugs or as biochemical agents to unravel the etiology of the disease.

Abstract
Purpose Since obesity is a risk factor for various diseases and is associated with increased oxidative stress conditions, some herbs are considered to be effective in reducing obesity and its complications. Methods This secondary analysis investigates the effect of Nigella sativa (N.S) oil supplement on total antioxidant capacity (TAC) and malondialdehyde (MDA) levels in obese/overweight women. Obese and overweight healthy women were randomized to receive 2,000 mg/d of N.S supplement and placebo. The intervention periods lasted 8 weeks and were separated by a 4-week washout period. Also, each participant was given an iso-calorie diet. Baseline characteristics and TAC and MDA levels were measured. Pkcross analysis was performed for statistical analysis using Stata software. Also, Cohen's d was estimated as effect size for all results to assess the magnitude of the effects. Results 39 women completed the study. N.S oil supplementation at a dose of 2000 mg/d significantly increased serum TAC (P effect = 0.017, Cohen's d = 1.81) and reduced serum MDA (P effect < 0/001, Cohen's d = - 0.32). Conclusion Based on our findings taking N.S supplementation for 8 weeks can improve antioxidant conditions in obese and overweight adults. However, more studies with a larger population and the presence of both genders need to be done to confirm the results.Registration number: IRCT20180430039475N1.

Impact of Best-Fitted Control Selection on Effect Size: An Example in Functional GI Disorder Case-Control Studies. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph181910296. [PMID: 34639595 PMCID: PMC8508498 DOI: 10.3390/ijerph181910296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 09/13/2021] [Accepted: 09/19/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Effect sizes are the most useful quantities for communicating the practical significance of results and helping to facilitate cumulative science. We hypothesize that the selection of the best-fitted controls can significantly affect the estimated effect sizes in case-control studies. Therefore, we decided to exemplify and clarify this effect on effect size using a large data set. The objective of this study was to investigate the association among variables in functional gastrointestinal disorders (FGIDs) and mental health problems, common ailments that reduce the quality of life of a large proportion of the community worldwide. METHOD In this methodological study, we constitute case and control groups in our study framework using the Epidemiology of Psychological, Alimentary Health and Nutrition (SEPAHAN) dataset of 4763 participants. We devised four definitions for control in this extensive database of FGID patients and analyzed the effect of these definitions on the odds ratio (OR): 1. conventional control: without target disorder/syndrome (sample size 4040); 2. without any positive criteria: criterion-free control (sample size 1053); 3. syndrome-free control: without any disorder/syndrome (sample size 847); 4. symptom-free control: without any symptoms (sample size 204). We considered a fixed case group that included 723 patients with a Rome III-based definition of functional dyspepsia. Psychological distress, anxiety, and depression were considered as dependent variables in the analysis. Logistic regression was used for association analysis, and the odds ratio and 95% confidence interval (95%CI) for OR were reported as the effect size. RESULTS The estimated ORs indicate that the strength of the association in the first case-control group is the lowest, and the fourth case-control group, including controls with completely asymptomatic people, is the highest. Ascending effect sizes were obtained in the conventional, criterion-free, syndrome-free, and symptom-free control groups. These results are consistent for all three psychological disorders, psychological distress, anxiety, and depression. CONCLUSIONS This study shows that a precise definition of the control is mandatory in every case-control study and affects the estimated effect size. In clinical settings, the selection of symptomatic controls using the conventional definition could significantly diminish the effect size.

Med Chem 2021; 17:146-157. [PMID: 32116195 DOI: 10.2174/1573406416666200302113729] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 10/24/2019] [Accepted: 12/04/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Helicobacter pylori infection is accountable for most of the peptic ulcer and intestinal cancers. Due to the uprising resistance towards H. pylori infection through the present and common proton pump inhibitors regimens, the investigation of novel candidates is the inevitable issue. Medicinal plants have always been a source of lead compounds for drug discovery. The research of the related effective enzymes linked with this gram-negative bacterium is critical for the discovery of novel drug targets. OBJECTIVE The aim of the study is to identify the best candidate to evaluate the inhibitory effect of thymoquinone and thymol against H. pylori oncoproteins, Cag A and Vac A in comparison to the standard drug, metronidazole by using a computational approach. MATERIALS AND METHODS The targeted oncoproteins, Cag A and Vac A were retrieved from RCSB PDB. Lipinski's rule and ADMET toxicity profiling were carried out on the phytoconstituents of the N. sativa. The two compounds of N. sativa were further analyzed by molecular docking and MD simulation studies. The reported phytoconstituents, thymoquinone and thymol present in N. sativa were docked with H. pylori Cag A and Vac A oncoproteins. Structures of ligands were prepared using ChemDraw Ultra 10 software and then changed into their 3D PDB structures using Molinspiration followed by energy minimization by using software Discovery Studio client 2.5. RESULTS The docking results revealed the promising inhibitory potential of thymoquinone against Cag A and Vac A with docking energy of -5.81 kcal/mole and -3.61kcal/mole, respectively. On the contrary, the inhibitory potential of thymol against Cag A and Vac A in terms of docking energy was -5.37 kcal/mole and -3.94kcal/mole as compared to the standard drug, metronidazole having docking energy of -4.87 kcal/mole and -3.20 kcal/mole, respectively. Further, molecular dynamic simulations were conducted for 5ns for optimization, flexibility prediction, and determination of folded Cag A and Vac A oncoproteins stability. The Cag A and Vac A oncoproteins-TQ complexes were found to be quite stable with the root mean square deviation value of 0.2nm. CONCLUSION The computational approaches suggested that thymoquinone and thymol may play an effective pharmacological role to treat H. pylori infection. Hence, it could be summarized that the ligands thymoquinone and thymol bound and interacted well with the proteins Cag A and Vac A as compared to the ligand MTZ. Our study showed that all lead compounds had good interaction with Cag A and Vac A proteins and suggested them to be a useful target to inhibit H. pylori infection.

Abstract
Mounting evidence support the potential benefits of functional foods or nutraceuticals for human health and diseases. Black cumin (Nigella sativa L.), a highly valued nutraceutical herb with a wide array of health benefits, has attracted growing interest from health-conscious individuals, the scientific community, and pharmaceutical industries. The pleiotropic pharmacological effects of black cumin, and its main bioactive component thymoquinone (TQ), have been manifested by their ability to attenuate oxidative stress and inflammation, and to promote immunity, cell survival, and energy metabolism, which underlie diverse health benefits, including protection against metabolic, cardiovascular, digestive, hepatic, renal, respiratory, reproductive, and neurological disorders, cancer, and so on. Furthermore, black cumin acts as an antidote, mitigating various toxicities and drug-induced side effects. Despite significant advances in pharmacological benefits, this miracle herb and its active components are still far from their clinical application. This review begins with highlighting the research trends in black cumin and revisiting phytochemical profiles. Subsequently, pharmacological attributes and health benefits of black cumin and TQ are critically reviewed. We overview molecular pharmacology to gain insight into the underlying mechanism of health benefits. Issues related to pharmacokinetic herb-drug interactions, drug delivery, and safety are also addressed. Identifying knowledge gaps, our current effort will direct future research to advance potential applications of black cumin and TQ in health and diseases.

Abstract
INTRODUCTION According to Rome IV, functional dyspepsia is diagnosed with the presence of dyspepsia in the absence of organic or metabolic causes. FD caused by several factors, such as impaired gastric accommodation and hypersensitivity to gastric distention. Several studies have reported the effectiveness of herbal medicine on FD. This article, thus, reviews Persian herbal medicine in FD. METHODS Electronic databases, including Pubmed, Scopus, Cochrane, Embase, Web of science and Ovid, were searched so as to find clinical articles related to dyspepsia and herbal medicine by July 2019. Our search strategies were traditional medicine, complementary and alternative medicine, herb, plant, and dyspepsia. We excluded all articles except Persian clinical trials. RESULTS We found 34 clinical trials with 15 herbs and 4 compound herbal remedies like Asparagus racemosus, Brassica oleracea, Cynara scolymus, Ocimum basilicum, Mentha longifolia, Mentha pulegium, Mentha piperata, Pimpinella anisum, Nigella sativa, Mastic gum, Curcuma longa, Pistatio Atlantica, Glycyrrhiza glabra, Solanum tuberosum and Zingiber officinale and compound remedies of Rosa damascene & Crocus sativus, Trachyspermum copticom & Apium graveolence, Carum carvi & Mentha pipperata, Gingiber officinalis & Cynara scolymus are effective in functional dyspepsia. CONCLUSION Many people use herbal and traditional remedies for the treatment of disorders such as gastrointestinal disorders, especially in Asian countries. Several studies reported the efficacy of herbal medicine in functional dyspepsia. Although their mechanisms are not fully understood, it seems they can modulate GI motility and improve symptoms of FD.

Comparison of a Novel Herbal Medicine and Omeprazole in the Treatment of Functional Dyspepsia: A Randomized Double-Blinded Clinical Trial. Gastroenterol Res Pract 2020; 2020:5152736. [PMID: 33273914 PMCID: PMC7683154 DOI: 10.1155/2020/5152736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 10/10/2020] [Accepted: 10/28/2020] [Indexed: 11/18/2022] Open
Abstract
Background The Trachyspermum ammi L. (TA), Anethum graveolens L. (AG), and Zataria multiflora Boiss (ZM) herbal oils are among the most used herbal products in traditional medicine as the antiseptic, anesthetic, carminative, and antispasmodic. However, there are no clinical studies to evaluate the efficacy of the herbs mentioned in the treatment of functional dyspepsia (FD). This study was designed to appraise the efficacy and safety of a novel herbal medicine consisting of ZM, AG, and TA essential oils compared to omeprazole in FD treatment. Methods The present study was a randomized double-blind clinical trial with parallel groups in Iran. Patients in control and intervention arms received omeprazole 20 mg once a day and 250 mg soft-gel capsules containing 180 mg of essential oils of ZM, AG, and TA twice a day for two weeks, respectively. The primary outcome was the sufficient response rate in the postprandial distress syndrome (PDS) and/or epigastric pain syndrome (EPS) at the end of the intervention. Secondary outcomes were the improvement rate in the PDS, EPS, Gastrointestinal Symptom Rating Scale (GSRS), and quality of life scores. Also, safety and tolerability were assessed. Results The within-group comparison of EPS, PDS, total GSRS, GSRS Pain, and GSRS Dyspepsia scores with that at the end of the treatment indicated a significant reduction in both control and intervention groups (p < 0.001). However, after two weeks of treatment, the herbal medication and omeprazole arms were significantly different in the sufficient response rate based on PDS (p < 0.01) and EPS (p < 0.05) scores (78.3% (18/23) and 73.7% (14/19) in the intervention group vs. 36.4% (8/22) and 40.9% (9/22) in the control group). Also, the mean reduction in EPS (p < 0.05), PDS (p < 0.01), and GSRS (p < 0.001) scores after treatment was significantly higher in the intervention group than control group. Conclusion Based on the study findings, this herbal medicine can be considered as an appropriate treatment of FD. However, a larger multicenter trial is needed to confirm the results of the trial.

The beneficial health effects of Nigella sativa on Helicobacter pylori eradication, dyspepsia symptoms, and quality of life in infected patients: A pilot study. Phytother Res 2020; 34:1367-1376. [PMID: 31916648 DOI: 10.1002/ptr.6610] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2018] [Revised: 11/27/2019] [Accepted: 12/23/2019] [Indexed: 01/02/2023]
Abstract
The aim of this study was to evaluate the effects of Nigella sativa (N. sativa) in addition to quadruple-therapy on Helicobacter pylori eradication, dyspepsia, biochemical-markers, and quality of life in infected patients. In this double-blind placebo-controlled clinical-trial, 51 H. pylori infected patients with functional dyspepsia were randomly assigned to treatment (quadruple-therapy with 2 g/day N. sativa) or placebo groups (quadruple-therapy with 2 g/day placebo) for 8 weeks. Serum levels of interleukin-8 (IL-8), high-sensitivity C-reactive protein (hs-CRP) and malondialdehyde, quality of life, dyspepsia, food-intake, body-weight, and body mass index (BMI) were evaluated at the baseline and at the end of the study. H. pylori eradication was evaluated at the end of the intervention. At the end of the study, H. pylori eradication was more in the N. sativa group compared with the placebo (p = .01). Weight, BMI, and dietary-intake (p < .05) increased significantly as compared with placebo. A significant improvement was also observed in patients' quality of life in the treatment group compared with the placebo (p < .05). The differences of biochemical-markers and dyspepsia between the two groups were not significant. So, N. sativa supplementation with medical treatment may have beneficial effects on H. pylori eradication, weight, BMI, dietary-intake, and quality of life in infected patients.

Abstract
Urease is a nickel-dependent metalloenzyme found in plants, some bacteria, and fungi. Bacterial enzyme is of special importance since it has been demonstrated as a potent virulence factor for some species. Especially it is central to Helicobacter pylori metabolism and virulence being necessary for its colonization of the gastric mucosa, and is a potent immunogen that elicits a vigorous immune response. Therefore, it is not surprising that efforts to design, synthesize and evaluate of new inhibitors of urease are and active field of medicinal chemistry. In this paper recent advances on this field are reviewed.
