Abstract
Helicobacter pylori (H. pylori) is a 0.5-1 µm wide, 2-4 µm long, short helical, S-shaped Gram-negative microorganism. It is mostly found in the pyloric region of the stomach and causes chronic gastric infection. It is estimated that these bacteria infect more than half of the world's population. The mode of transmission and infection of H. pylori is still not known exactly, but the faecal-oral and oral-oral routes via water or food consumption are thought to be a very common cause. In the last three decades, research interest has increased regarding the pathogenicity, microbial activity, genetic predisposition, and clinical treatments to understand the severity of gastric atrophy and gastric cancer caused by H. pylori. Studies have suggested a relationship between H. pylori infection and malabsorption of essential micronutrients, and noted that H. pylori infection may affect the prevalence of malnutrition in some risk groups. On the other hand, dietary factors may play a considerably important role in H. pylori infection, and it has been reported that an adequate and balanced diet, especially high fruit and vegetable consumption and low processed salty food consumption, has a protective effect against the outcomes of H. pylori infection. The present review provides an overview of all aspects of H. pylori infection, such as clinical features, treatment, and nutrition.

Abstract
The gram-negative bacterium, Helicobacter pylori (H. pylori), infection is predominantly known for its strong association with development of gastric diseases, including gastritis, peptic ulcers, and stomach cancer. Numerous clinical reports show that ascorbic acid deficiency has been connect with gastritis. Vitamin C levels both in gastric acid and serum have constantly been affirmed to be low in subjects with H. pylori infected gastritis and peptic ulcers. Ascorbic acid supplementation likely relates to reduced incidences of bleeding from peptic ulcers and gastric cancer. H. pylori eradication is shown to increase vitamin C levels, while the benefits of ascorbic acid oral intake to increase the effectiveness of H. pylori-eradication therapy are controversial. Recent studies suggest that ascorbate intake intravenously, but not orally; pharmacologic ascorbate concentrations up to 30 mmol/L in blood, several millimolar in tissues as well as in interstitial fluid, are easily and safely achieved. Pharmacologic ascorbate can exert pro-oxidant effects locally as a drug by mediating hydrogen peroxide (H2O2) formation, which was applied to animal and clinical trials of cancer, sepsis, and severe burns etc. In this review, we summarize current understanding of the associations of vitamin C and H. pylori infection, and outline some potential strategies for H. pylori intervention from emerging advances on ascorbic acid physiology and pharmacology.

Abstract
The treatment of Helicobacter pylori (H. pylori) induced infections using antibiotic therapies is clinically well accepted; however, using a noninvasive approach with the implementation of therapeutic agents such as vitamin C is not well investigated. Vitamin C has certain characteristics, which allow for it to be considered as a potential treatment option for patients with H. pylori infections. Vitamin C's hostility and mechanism of action towards H. pylori infection in peptic ulcer disease can be classified into two categories: as a preventative agent and alternatively as a therapeutic agent. Preventatively vitamin C acts as a biological antioxidant as well as an immune boosting agent, while therapeutically it acts as an inhibitor of urease, a potential collagen synthesizing agent, and a stimulant in prostaglandin synthesis. As a result, the dosage of vitamin C should be highly regulated. Furthermore, numerous studies have shown that vitamin C supplementation if taken with antibiotics can increase the efficiency of the treatment leading to an increased possibility of eradication of H. pylori in infected individuals. This paper will investigate the recent studies that show different mechanisms through which vitamin C can be used as a preventative or a therapeutic agent for the treatment of H. pylori related infections.

Anti-inflammatory mechanism of polyunsaturated fatty acids in Helicobacter pylori-infected gastric epithelial cells. Mediators Inflamm 2014; 2014:128919.

Abstract
Helicobacter pylori is an important risk factor for gastric inflammation, which is mediated by multiple signaling pathways. The aim of this study was to investigate the effects of polyunsaturated fatty acids (PUFAs), such as linoleic acid (LA), alpha-linolenic acid (ALA), and docosahexaenoic acid (DHA), on the expression of the proinflammatory chemokine interleukin-8 (IL-8) in H. pylori-infected gastric epithelial AGS cells. To investigate whether PUFAs modulate H. pylori-induced inflammatory signaling, we determined the activation of epidermal growth factor receptor (EGFR), protein kinase C-δ (PKC δ), mitogen-activated protein kinases (MAPKs), nuclear factor-kappa B (NF- κB), and activator protein-1 (AP-1) as well as IL-8 expression in H. pylori-infected gastric epithelial cells that had been treated with or without PUFAs. We found that PUFAs inhibited IL-8 mRNA and protein expression in H. pylori-infected cells. ω-3 fatty acids (ALA, and DHA) suppressed the activation of EGFR, PKC δ, MAPK, NF- κB, and AP-1 in these infected cells. LA did not prevent EGFR transactivation and exhibited a less potent inhibitory effect on IL-8 expression than did ALA and DHA. In conclusion, PUFAs may be beneficial for prevention of H. pylori-associated gastric inflammation by inhibiting proinflammatory IL-8 expression.

Abstract
The discovery of Helicobacter pylori as the cause of gastritis and peptic ulcers ushered in the modern era of research into gastritis and into acid-peptic diseases and rekindled interest in the role of ascorbic acid in the pathophysiology and treatment of gastritis and peptic ulcer disease. Here, we review historic and modern studies on ascorbic acid and gastric diseases with an emphasis on H. pylori gastritis and its sequelae. The relationship of ascorbic acid and gastritis and peptic ulcer and its complications was extensively studied during the 1930s through the 1950s. Much of this extensive literature has been effectively "lost." Ascorbic acid deficiency was associated with all forms of gastritis (e.g., autoimmune, chemical, and infectious) due in varying degrees to insufficient intake, increased metabolic requirements, and destruction within the GI tract. Importantly, gastritis-associated abnormalities in gastric ascorbic acid metabolism are reversed by H. pylori-eradication and potentially worsened by proton pump inhibitor therapy. Diets rich in naturally occurring ascorbic acid are associated with protection of the gastric corpus from atrophy and a reduction in the incidence of gastric cancer possibly through the ability of ascorbic acid to reduce oxidative damage to the gastric mucosa by scavenging carcinogenic N-nitroso compounds and free radicals and attenuating the H. pylori-induced inflammatory cascade. Ascorbic acid supplementation was possibly associated with a decreased incidence of bleeding from peptic ulcer disease. Pharmacologic doses of ascorbic acid also may improve the effectiveness of H. pylori-eradication therapy. Occasionally, looking back can help plot the way forward.

Abstract
Potential of nonantibiotic therapies for treatment of Helicobacter pylori-related acid peptic disease remains underexplored. Several clinical studies have shown that higher prevalence of H. pylori infection is associated with low Vitamin C (Vit C) level in serum and gastric juice. However, there is no consensus regarding the usefulness of Vit C supplementation in the management of H. pylori infection. Surveying the existing literature we conclude that high concentration of Vit C in gastric juice might inactivate H. pylori urease, the key enzyme for the pathogen's survival and colonization into acidic stomach. Once infection established, urease is not very important for its survival. The role of Vit-C as anti-H. pylori agent in peptic ulcer diseases appears to be preventive rather than curative. Rather than supplementing high dose of Vit C along with conventional triple therapy, it is preferable to complete the conventional therapy and thereafter start Vit C supplementation for extended period which would prevent reinfection in susceptible individuals, provided the patients are not achlorhydric. Further studies are required to prove the role of Vit C in susceptible population.

Abstract
Vitamins C and E can act as potent antioxidants to reduce the damage caused by reactive oxygen species in gastric mucosa. Whether vitamin supplements for Helicobacter pylori eradication regimen could improve the rate of eradication remains uncertain. Therefore, we performed a meta-analysis to evaluate the efficacy of vitamins C and E supplementation for the eradication of H. pylori. Searches were conducted in the databases PubMed, EMBASE and Cochrane Library. Randomised controlled trials (RCT) that fulfilled the inclusion criteria and addressed the clinical questions of this analysis were further assessed. Of the six RCT included, five had a low methodological quality. Of the six RCT, three compared the efficacy of the eradication regimen v. eradication regimen plus vitamins C and E. The result of the meta-analysis showed a non-significant difference in the eradication rate of H. pylori between the two groups (risk ratio (RR) 0·93, P = 0·76). Another three RCT compared the eradication regimen v. eradication regimen plus vitamin C only, and there too there was no significant difference in the eradication rate (RR 0·83, P = 0·32). In conclusion, vitamins C and/or E supplements to the H. pylori eradication regimen could not improve the eradication rate. However, currently available data do not draw a definitive conclusion about the effectiveness of antioxidant vitamins on H. pylori eradication, owing to the small sample size and low-to-moderate methodological quality.

Abstract
BACKGROUND Vitamin C in gastric juice and in vitro has been shown to inhibit the growth of Helicobacter pylori (H. pylori). AIMS The purpose of this study was to investigate the effect of addition of vitamin C to eradication regimen on H. pylori eradication rate. PATIENTS This randomised controlled clinical trial was conducted on 312 patients with H. pylori infection who had referred to the Taleghani Research Center of Gastroenterology and Liver Disease. METHODS Patients were randomly divided into two groups. Group A patients (162 patients) received amoxicillin 1g and metronidazole 500 mg b.i.d., bismuth 240 mg b.i.d. and omeprazole 40 mg q.i.d. in two divided doses. Patients in group B (150 patients) received the same regimen plus 500 mg vitamin C per day. All patients received therapy for 2 weeks. Four weeks later all patients underwent urea breath test and results were compared. RESULTS A total of 140 patients in group A and 141 in group B completed the study. On intention-to-treat analysis 48.8% of patients in group A in comparison to 78% in group B responded to eradication therapy and had negative urea breath test (p<0.0001). CONCLUSION Addition of vitamin C to H. pylori treatment regimen of amoxicillin, metronidazole and bismuth can significantly increases H. pylori eradication rate.

Abstract
Micronutrient supplementation offers one of the most cost-effective means of improving the health and survival of children in developing countries. However, the effects of supplementation with single micronutrients on diarrhea are not always consistent, and supplementation with multi-micronutrient supplements can have negative effects. These inconsistencies may result from the failure to consider the diverse etiological agents that cause diarrhea and the unique effects each micronutrient has on the immune response to each of these agents. This review examines the separate effects that supplementation with the B-complex vitamins, vitamin C, vitamin E, selenium, and iron have on diarrheal disease-related outcomes. Supplementation with iron may increase the risk of infection by invasive diarrheal pathogens, while supplementation with the remaining micronutrients may reduce this risk. These differences may be due to distinct regulatory effects each micronutrient has on the pathogen-specific immune response, as well as on the virulence of specific pathogens. The findings of these studies suggest that micronutrient supplementation of children must take into account the pathogens prevalent within communities as reflected by their diarrheal disease burdens. The effectiveness of combining multiple micronutrients into one supplement must also be reconsidered.

Abstract
Vitamin C or ascorbic acid is a hydrosoluble vitamin derived from glucose metabolism. It acts as a reductor agent required for synthesis of collagen fibers through hydroxylation of proline and lysine. It also protects the body against damage caused by the free radicals. Humans cannot synthesize ascorbic acid as they lack an enzyme called gulonolactone oxidase. Concentrations in plasma and leukocytes reflect the levels of the diet and body deposits respectively of this vitamin. Among foods with high vitamin C levels are tomatoes, potatoes, and citrus fruits such as limes, oranges and lemons. The current recommendation of daily intake of vitamin C is 90 mg/d for men and 75 mg/d for women. Patients with chronic diseases such as cancer or diabetes or those who smoke need higher doses in their usual diet. Ascorbic acid deficiency gives rise to the appearance of scurvy. This disease is rarely seen in developed countries. The symptoms develop with plasma levels below 0.15 mg/dL. Scurvy is characterized by the presence of weakness, joint pain or skin lesions in form of petechias, gum bleeding, ease of developing bruises or delay in wound healing. The most characteristic skin manifestations are purpuric perifollicular hyperkeratotic papules and the presence of kinky hair.
