Association between rosacea and helicobacter pylori infection: A meta-analysis. PLoS One 2024; 19:e0301703. [PMID: 38574094 PMCID: PMC10994334 DOI: 10.1371/journal.pone.0301703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 03/19/2024] [Indexed: 04/06/2024] Open
Abstract
BACKGROUND AND OBJECTIVES The potential association between rosacea and a heightened prevalence of Helicobacter pylori (HP) infection has been previously suggested. However, existing studies offer inconsistent results. This systematic review and meta-analysis aimed to elucidate the relationship between rosacea and HP infection. METHODS We conducted comprehensive searches of PubMed, Embase, and Web of Science databases to identify relevant observational studies for our investigation. We utilized the random-effects model to aggregate the data to address the potential influence of heterogeneity among the studies on the outcome. RESULTS Our analysis incorporated twenty-five datasets from 23 case-control and cross-sectional studies, encompassing 51,054 rosacea patients and 4,709,074 controls without skin disease. The pooled results revealed a significantly higher prevalence of HP infection in individuals with rosacea compared to controls (odds ratio [OR]: 1.51, 95% confidence interval [CI]: 1.17-1.95, p<0.001; I2 = 79%). Subgroup analysis indicated an increased prevalence of HP infection in rosacea studies that utilized one (OR: 1.72, 95% CI: 1.11-2.66, p = 0.02; I2 = 76%) or more tests for HP infection (OR: 2.26, 95% CI: 1.29-3.98, p = 0.005; I2 = 56%). However, this association was not observed in population-based studies that determined HP infection based on prescription records for HP eradication drugs (OR: 0.90, 95% CI: 0.76-1.07, p = 0.024; I2 = 54%). CONCLUSION Rosacea may be significantly associated with a higher prevalence of HP infection. High-quality prospective studies with delicately controlled confounding factors are needed to determine if HP infection is a risk factor for rosacea.

Helicobacter pylori infection: a dynamic process from diagnosis to treatment. Front Cell Infect Microbiol 2023; 13:1257817. [PMID: 37928189 PMCID: PMC10621068 DOI: 10.3389/fcimb.2023.1257817] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 10/05/2023] [Indexed: 11/07/2023] Open
Abstract
Helicobacter pylori, a gram-negative microaerophilic pathogen, causes several upper gastrointestinal diseases, such as chronic gastritis, peptic ulcer disease, and gastric cancer. For the diseases listed above, H. pylori has different pathogenic mechanisms, including colonization and virulence factor expression. It is essential to make accurate diagnoses and provide patients with effective treatment to achieve positive clinical outcomes. Detection of H. pylori can be accomplished invasively and noninvasively, with both having advantages and limitations. To enhance therapeutic outcomes, novel therapeutic regimens, as well as adjunctive therapies with probiotics and traditional Chinese medicine, have been attempted along with traditional empiric treatments, such as triple and bismuth quadruple therapies. An H. pylori infection, however, is difficult to eradicate during treatment owing to bacterial resistance, and there is no commonly available preventive vaccine. The purpose of this review is to provide an overview of our understanding of H. pylori infections and to highlight current treatment and diagnostic options.

Effects of Helicobacter pylori Infection on the Prognosis of Chronic Atrophic Gastritis by Inducing the Macrophage Polarization. Gastroenterology Res 2023; 16:226-233. [PMID: 37691749 PMCID: PMC10482605 DOI: 10.14740/gr1636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 06/22/2023] [Indexed: 09/12/2023] Open
Abstract
Background Recently, the effects of Helicobacter pylori (H. pylori) infection on the prognosis of chronic atrophic gastritis (CAG) are still unclear. The aim of our study was to discuss the role of H. pylori infection on the prognosis of CAG by inducing the M1/M2 macrophage polarization. Methods A total of 180 subjects as control (group 1), CAG patients without H. pylori infection (group 2) and H. pylori-associated CAG patients (group 3) were respectively recruited for this cross-sectional investigation in Daqing Oilfield General Hospital from May 2019 to July 2020. Their serum samples were collected to determine the concentrations of pro-inflammatory and anti-inflammatory cytokines. Meanwhile, the gastric mucosa was excised to determine the related gene expressions on the M1/M2 macrophage polarization. Then the prognosis of CAG was evaluated according to the status of clinical manifestations and endoscopic examination after the follow-up. Results Notably, it was proved that compared with the control group, the expressions and concentrations of pro-inflammatory cytokines (M1 macrophage: inducible nitric oxide synthase (iNOS), tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), and interleukin-6 (IL-6)) were significantly higher, while the anti-inflammatory cytokines (M2 macrophage: arginase-1 (Arg-1), IL-4 and IL-10) were apparently reduced in the group 2 and group 3 (P < 0.05). Moreover, more days were needed for the prognosis of CAG in group 3 than those in group 2, which was accompanied by higher expressions of pro-inflammatory and lower anti-inflammatory cytokines at the baseline (P < 0.05). Furthermore, negative correlations were shown between the concentrations of iNOS, TNF-α, IFN-γ and IL-6, and the prognosis of CAG (P < 0.05), while positive correlations were observed between the contents of IL-4 and IL-10, and prognosis of CAG (P < 0.05). Conclusion These above results indicated that H. pylori infection-induced disorders of M1/M2 macrophage polarization could affect the prognosis of CAG.

The Role of Cosmetology in an Effective Treatment of Rosacea: A Narrative Review. Clin Cosmet Investig Dermatol 2023; 16:1419-1430. [PMID: 37303984 PMCID: PMC10252991 DOI: 10.2147/ccid.s412800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 05/17/2023] [Indexed: 06/13/2023]
Abstract
Rosacea is a chronic inflammatory facial skin disease usually occurring in middle-aged patients. It manifests itself as an inflammatory condition with perivascular infiltrate, dilated blood vessels, lymphoedema, hyperplasia of sebaceous glands, and disorders of connective tissue structures brought on by fibrosis. Rosacea is characterized by multifactorial inflammatory mechanisms, and therefore it requires an interdisciplinary approach including adequate skin care, topical and/or systemic therapy, and physical modalities to successfully treat the various symptoms and disease subtypes. However, data regarding the possible role of cosmetologists in rosacea remains scanty and equivocal. The objectives of cosmetology therapy include restoration and regeneration, anti-inflammatory effects, the strengthening of blood vessels and regulation of their permeability, and the regulation of keratinization. Vascular abnormalities can be targeted with specific light and laser devices. Therefore, the present paper aims to review the latest advances and summarize different aspects concerning skin care in rosacea. Particular attention has been paid to the co-operation of cosmetologists with other specialists in order to bring about the interdisciplinary management of rosacea. It is also important to keep in mind that it is usually necessary to combine various methods of treatment, as this approach is more effective than monotherapy for attaining satisfactory cosmetic results in rosacea patients.

Worldwide Prevalence and Risk Factors of Helicobacter pylori Infection in Children. CHILDREN 2022; 9:children9091359. [PMID: 36138669 PMCID: PMC9498111 DOI: 10.3390/children9091359] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 08/22/2022] [Accepted: 09/03/2022] [Indexed: 01/17/2023]
Abstract
Helicobacter pylori is usually acquired during childhood. The reports from the last two decades pointed out a decrease in H. pylori prevalence across geographical areas worldwide compared to previously reported data. Most of the studies performed in America found an overall H. pylori infection prevalence of approximately 50%. The most important risk factors in America include being male, poor adherence or difficult access to treatment, and the lack of in-home water service. Despite the descending trend in prevalence worldwide, the overall prevalence in Africa remains very high (70%). Nevertheless, the prevalence of H. pylori in children without gastrointestinal who underwent screening was reported to be only 14.2%. The main risk factors in Africa are having a traditional pit or no toilet, poverty, birth order, source of drinking water, or being a farmer. Asia seems to have the widest variations in terms of H. pylori prevalence. Several risk factors were reported in Asia to be associated with this infection, such as lower income and educational level, house crowding, rural residence, ethnicity, the use of tanks as water supplies, alcohol drinking, active smoking, eating spicy food or raw uncooked vegetables, poor living conditions and sanitation. The overall prevalence of H. pylori infection in European children is almost 25%. Portugal has the highest prevalence of all European countries at 66.2% in children 13 years of age. The risk factors in European individuals consist of living in rural areas, eating unwashed fruits and vegetables, not washing hands after school, low parental education and unemployment, and short education duration. Further studies are required to identify the precise mechanisms involved in the discrepancies of H. pylori prevalence worldwide.

Old and New Aspects of H. pylori-Associated Inflammation and Gastric Cancer. CHILDREN 2022; 9:children9071083. [PMID: 35884067 PMCID: PMC9322908 DOI: 10.3390/children9071083] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 07/17/2022] [Accepted: 07/18/2022] [Indexed: 12/16/2022]
Abstract
H. pylori is involved in the development of 80% of gastric cancers and 5.5% of all malignant conditions worldwide. Its persistence within the host’s stomach causes chronic inflammation, which is a well-known hallmark of carcinogenesis. A wide range of cytokines was reported to be involved in the initiation and long-term persistence of this local and systemic inflammation. IL-8 was among the first cytokines described to be increased in patients with H. pylori infection. Although, this cytokine was initially identified to exert a chemoattracting effect that represents a trigger for the activation of inflammatory cells within H.-pylori-infected mucosa, more recent studies failed in encountering any association between IL-8 and H. pylori infection. IL-6 is a multifunctional, pleiotropic and multipotent cytokine involved in mediating the interaction between innate and adaptive immunity with a dichotomous role acting as both a proinflammatory and an anti-inflammatory cytokine depending on the signaling pathway. IL-1α functions as a promoter of angiogenesis and vascular endothelial cell proliferation in gastric carcinoma since it is closely related to H.-pylori-induced inflammation in children. IL-1β is an essential trigger and enhancer of inflammation. The association between a low IL-1β level and an increased TNF-α level might be considered a risk factor for peptic ulcer disease in the setting of H. pylori infection. IL-10 downregulates both cytotoxic inflammatory responses and cell-mediated immune responses. H. pylori uses the immunosuppressive role of IL-10 to favor its escape from the host’s immune system. TGFβ is a continuous inflammatory mediator that promotes the adherence of H. pylori to the host’s cells and their subsequent colonization. The role of H.-pylori-induced inflammatory responses in the onset of gastric carcinogenesis seems to represent the missing puzzle piece for designing effective preventive and therapeutic strategies in patients with H.-pylori-associated gastric cancer.

The impact of clinical nutrition on inflammatory skin diseases. J Dtsch Dermatol Ges 2022; 20:185-202.

Abstract
The influence of nutrition on the pathophysiology and clinical severity of inflammatory facial dermatoses such as acne, rosacea, seborrheic dermatitis, and perioral dermatitis has been controversially discussed for years. As part of a modern treatment approach, clinicians should provide patients with information on how their choice of diet might impact their dermatologic diagnosis and could potentially enhance therapeutic outcome. Recently, the concept of a gut-skin axis has gained momentum in the understanding of inflammatory dermatoses, with nutrition considered a contributing factor in this context. For example, gastrointestinal symptoms in rosacea patients may indicate a dysbiosis of the gut microbiome, treatment of which may also improve severity of the skin disease. New research efforts were recently made for acne patients addressing the clinical effects of omega-3 fatty acids and probiotics. In contrast, due to the limited data available, no comparable specific dietary recommendations can yet be made for seborrheic or perioral dermatitis. However, there are promising signs that clinical nutrition and dermatology will be more extensively interlinked in the future, both clinically and scientifically.

Abstract
The aim of this study was to define the relationship between several environmental, laboratory, and genetic factors, i.e., TLR2 and NLRP3 polymorphisms, and Helicobacter pylori (H. pylori) infection in children, by comparing three different groups of pediatric subjects: H. pylori-induced gastritis, non-H. pylori gastritis, and healthy controls. Our final study sample included 269 children, which were divided into three groups according to the histopathological exam: group 1 with 51 children with H. pylori-induced gastritis, group 2 with 103 children with H. pylori-negative gastritis, and group 3 (control group) with 115 children without any histopathological changes. All children underwent a thorough anamnesis, clinical exam, laboratory tests, and upper digestive endoscopy with gastric biopsy for rapid urease test, histopathological exam, and genetic analysis of TLR2 rs3804099, TLR2 rs3804100, and NLRP3 rs10754558 gene polymorphisms. We noticed a significant association between living conditions and the type of gastritis (p < 0.0001). Both rapid urease and serological tests were significantly associated with the presence of H. pylori (p < 0.0001). The CT variant genotype of TLR2 rs380499 was significantly associated with neutrophil count (p = 0.0325). We noticed a significant association between the CC variant genotype of NLRP3 rs10754558 and leucocytes, neutrophils, eosinophils, as well as ALT (p = 0.0185, p = 0.0379, p = 0.0483, p = 0.0356). Based on these findings, we state that poor living conditions and rural areas represent risk factors for H. pylori infection. The rapid urease test is a reliable diagnostic tool for this infection. CT and TT carriers of TLR2 rs3804099, as well as CC carriers of NLRP3 rs10754558, might display a more severe degree of systemic inflammation.

Abstract
The human intestine hosts diverse microbial communities that play a significant role in maintaining gut-skin homeostasis. When the relationship between gut microbiome and the immune system is impaired, subsequent effects can be triggered on the skin, potentially promoting the development of skin diseases. The mechanisms through which the gut microbiome affects skin health are still unclear. Enhancing our understanding on the connection between skin and gut microbiome is needed to find novel ways to treat human skin disorders. In this review, we systematically evaluate current data regarding microbial ecology of healthy skin and gut, diet, pre- and probiotics, and antibiotics, on gut microbiome and their effects on skin health. We discuss potential mechanisms of the gut-skin axis and the link between the gut and skin-associated diseases, such as psoriasis, atopic dermatitis, acne vulgaris, rosacea, alopecia areata, and hidradenitis suppurativa. This review will increase our understanding of the impacts of gut microbiome on skin conditions to aid in finding new medications for skin-associated diseases.

Abstract
Rosacea is a common inflammatory skin condition with four main clinical subtypes: erythematotelangiectatic, papulopustular, rhinophymatous, and ocular. Although several genetic and environmental factors have been linked with triggering rosacea, the pathogenesis still remains poorly understood. There is an increasing evidence in the literature to support that rosacea is a harbinger of several systemic comorbidities and may represent a chronic, systemic, inflammatory state. We have provided the most up-to-date evidence on the association between rosacea and several systemic diseases, discussing that rosacea is not just a skin disorder but a systemic disease process.

Abstract
BACKGROUND Innate immunity was found to be associated with both persistence of Helicobacter pylori (H. pylori) infection and increased risk of gastric cancer.
AIM To identify the risk factors associated with H. pylori infection and to establish the role of TLR9 rs352140 in suppressing or promoting inflammation related to this infection in children.
METHODS We performed a study of 155 children with digestive symptoms, who were divided into two groups according to the histopathological exam: Group 1 – 48 children with H. pylori-induced chronic gastritis, and Group 2 – control group.
RESULTS Rural area and poor living conditions were significantly associated with H. pylori chronic gastritis (P = 0.0042/P < 0.0001). Both positive immunoglobulin A anti H. pylori and the rapid urease test were significantly associated with H. pylori infection (P < 0.0001). Significantly higher values of leukocytes and neutrophils within the peripheral blood were found in children with H. pylori chronic gastritis (P = 0.111/P = 0.284). We found a significant positive correlation between the variant TT genotype of TLR9 rs352140 polymorphism and both leucocytes and neutrophils (P = 0.0225/P = 0.0292).
CONCLUSION Variant TT genotype carriers of the TLR9 rs352140 gene polymorphism might have a more severe degree of inflammation.

Abstract
A higher incidence of gastrointestinal diseases has been well established in patients with rosacea. However, no screening tool has been introduced for gastrointestinal disease development in rosacea. Fecal calprotectin (FC) is a calcium-binding protein, mainly derived from polymorpho-nuclear cells, such as neutrophils. It has been established as a marker of gastrointestinal inflammation. The aim of the present study was to evaluate FC levels in patients with rosacea without any gastrointestinal diseases. A prospective, case-control study was planned to investigate the relationship between rosacea and gastrointestinal involvement by evaluating FC levels and the Gastrointestinal Symptom Rating Scale (GSRS). A total of 47 patients with rosacea and 39 healthy control subjects were included in the study. The FC levels were statistically significantly higher in rosacea group than in the control group (65.96 ± 58.86 ng/mL vs 31.99 ± 20.12 ng/mL, P = .026, respectively). A statistically significant difference was also observed in GSRS values between the patient and the control groups (30.26 ± 12.48 vs 22.62 ± 7.64, P = .001, respectively). A positive correlation was noted between FC levels and the values of GSRS in the study group (r: 0.354; P = .001) and in the rosacea group (r = 0.392, P = .006). The measurement of FC may be useful in the early detection of gastrointestinal system diseases that may accompany rosacea and may provide a pathway to develop treatment strategies targeting both skin and intestinal mucosa.

Abstract
Rosacea is a chronic inflammatory disease with complicated pathophysiology that involves genetic and environmental elements and dysregulation of innate and adaptive immunity, neurovascular responses, microbiome colonization or infection, resulting in recurrent inflammation. Rosacea has been reported associated with various gastrointestinal diseases including inflammatory bowel disease, celiac disease, irritable bowel syndrome, gastroesophageal reflux disease, Helicobacter pylori (HP) infection, and small intestine bacterial overgrowth (SIBO). The link may involve common predisposing genetic, microbiota, and immunological factors, comprising the theory of the gut–skin axis. Although the evidence is still controversial, interestingly, medications for eradicating SIBO and HP provided an effective and prolonged therapeutic response in rosacea, and conventional therapy for which is usually disappointing because of frequent relapses. In this article, we review the current evidence and discuss probable mechanisms of the association between rosacea and gastrointestinal comorbidities.

Abstract
The increasingly wide use of next-generation sequencing technologies has revolutionised our knowledge of microbial environments associated with human skin, gastrointestinal tract and blood. The collective set of microorganisms influences metabolic processes, affects immune responses, and so directly or indirectly modulates disease. Rosacea is a skin condition of abnormal inflammation and vascular dysfunction, and its progression is affected by Demodex mites on the skin surface. When looking into the effects influencing development of rosacea, it is not only the skin microbiome change that needs to be considered. Changes in the intestinal microbiome and their circulating metabolites, as well as changes in the blood microbiome also affect the progression of rosacea. Recent research has confirmed the increased presence of bacterial genera like Acidaminococcus and Megasphera in the intestinal microbiome and Rheinheimera and Sphingobium in the blood microbiome of rosacea patients. In this review we discuss our current knowledge of the interactions between the immune system and the skin, gut and blood microbiome, with particular attention to rosacea diagnostic opportunities.

Abstract
Introduction: Rosacea is manifested by erythema and telangiectasias limited to the regions of cheeks, nose, chin and forehead. Data from the literature indicate a possible causal relationship between Helicobacter pylori infection in the gastrointestinal tract and rosacea, which is confirmed by the improvement of symptoms and clinical picture of rosacea after administered Helicobacter pylori eradication therapy. The aim of the paper was to determine the frequency of Helicobacter pylori infection in patients with rosacea and to examine the effect of the therapy for eradication of infection of this microorganism on the clinical course of rosacea. Methods: Sixty patients with a diagnosis of rosacea who were treated in 2018 at the Clinic for Skin and Venereal Diseases of the University Clinical Centre of Republic of Srpska were analysed. Patients were examined during their visit to a dermatologist (first week) and after applied therapy (sixth week). Subjects were divided into two groups-group I consisted of subjects in which, in addition to rosacea, the presence of Helicobacter pylori was registered and for whom the topical therapy and triple therapy for eradication of Helicobacter pylori were administered, and group II, which included subjects in which, in addition to rosacea, the presence of Helicobacter pylori was not registered and for whom only topical therapy was administered. Statistical processing was performed in the IBM SPSS Statistics 21 software package. Results: Helicobacter pylori infection was registered in 45 % of patients. Statistical significance was determined between the presence of Helicobacter pylori infection and the presence of pustules in patients with rosacea (p = 0.027), with an occurrence of pustules significantly more frequent in patients belonging to group I (55.6 %) than in patients belonging to group II (24.2 %). Conclusion: Therapy for eradicating Helicobacter pylori infection improves the clinical course of rosacea, especially in the stage of papules and pustules.

Abstract
Rosacea is a common chronic cutaneous inflammatory disorder. Recently, patients with rosacea were identified as having a higher risk of developing various comorbidities such as cardiovascular disease, psychiatric disorders, neurologic disorders, and gastrointestinal disorders. However, the risks of some comorbidities in patients with rosacea are somewhat contradictory, depending upon the study design. Moreover, pathomechanisms associated with the comorbidities of patients with rosacea remain poorly elucidated. The purpose of this review was to provide the most up-to-date evidence on the risks of neuropsychiatric and gastrointestinal comorbidities in patients with rosacea. Moreover, the molecular pathomechanisms associated with neuropsychiatric and gastrointestinal comorbidities in patients with rosacea were evaluated based on recent studies. This review was also intended to focus more on the role of the gut–brain–skin axis in the association of neuropsychiatric and gastrointestinal comorbidities in rosacea.

[PMID: 32333495 DOI: 10.1111/jocd.13409] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2020] [Revised: 03/16/2020] [Accepted: 03/17/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Helicobacter pylori (H pylori) may play a role in the pathogenesis of extra-intestinal disorders including dermatological diseases. AIMS This study aimed to assess the levels of H pylori antigen and antibody in patients with acne vulgaris (AV). METHODS This cross-sectional study compared the levels of fecal H pylori antigen and serum H pylori antibody in 100 patients with AV and 100 age and sex-matched healthy volunteers. Patients with AV were classified into mild, moderate, and severe according to the Global Acne Grading Scale. Levels of fecal H pylori antigen and serum H pylori antibodies were assessed using commercially available enzyme-linked immune-sorbent assay. RESULTS The patients with severe AV had significantly higher levels of fecal H pylori antigen as compared to the patients with mild AV, moderate AV, and healthy controls (P < .001). The patients with severe AV had significantly higher serum H pylori antibody as compared to the patients with mild AV, moderate AV, and healthy controls (P = .001). The levels of fecal H pylori antigen and serum H pylori antibody in the patients with mild AV were not significantly different from those in the patients with moderate AV (P = .49 and P = .05, respectively). CONCLUSION The patients with severe AV had higher levels of fecal H pylori antigen and serum H pylori antibody as compared to the patients with mild and moderate AV and with healthy controls. The indicators of H pylori infection were positively correlated with the severity and duration of AV.

Abstract
Neutrophil to lymphocyte ratio (NLR) is a simple, noninvasive, inexpensive inflammatory marker that can useful in the assessment of inflammatory activity, especially in pediatric ages. The aim of our study was to establish correlations between the presence of Helicobacter pylori (HP) proved histologically and NLR in children.A prospective, case-control study was performed on 137 pediatric patients aged between 1 and 18 years, admitted in a Pediatric Tertiary Hospital from Romania, between April 2016 and January 2018. According to the histologic examination, the children were divided into 2 groups: group 1: 50 children with HP infection, and group 2: 87 children without any pathologic findings.The mean age for the study group was 12.86 ± 3.796 years, whereas for control group, it was 12.10 ± 3.879 years (P = .3001). HP infection was significantly more frequent among children from rural area (P = .0089). Epigastric pain and loss of appetite were significantly associated with HP infection (P = .0350 /P = .0281). We noticed that the leukocyte and neutrophil counts were significantly higher in group 1 (P = .0076/P = .0306). We did not find any significant statistical differences between the 2 groups in terms of lymphocytes, erythrocyte sedimentation rate, and NLR or other assessed laboratory parameters. Regarding the IgA antibodies anti-HP and rapid urease test, they were both significantly associated with histologically confirmed HP infection (P < .0001).Even though, we did not identify significant differences in term of NLR between HP-induced gastritis children and healthy controls, the mean NLR values were higher HP-positive patients.

Abstract
BACKGROUND Rosacea is an inflammatory disease affecting the central part of face characterized by persistent or recurrent episodes of erythema, papules, pustules and telangiectasias of unknown etiology. Helicobacter pylori (H. pylori) is a gram-negative bacillus, which is one of the main causes of chronic gastritis, gastric cancer and gastrointestinal ulcers. Recent evidences have suggested that H. pylori infection is closely related to the occurrence of diseases. In recent years, studies have found that Helicobacter pylori infection is associated with the occurrence of acne rosacea. So the treatment of Helicobacter pylori infection may be a therapeutic method of acne rosacea. But it continues to be controversial. In other studies, the treatment of Helicobacter pylori did not significantly reduce the severity of acne rosacea. To further explore the association between acne rosacea and Helicobacter pylori infection, a summarize method was used to study the relationship between acne rosacea and Helicobacter pylori, providing reference for clinical acne rosacea therapy. METHODS Systematic searches were conducted on Wanfang Data, CQVIP, Springer, Public Health Management Corporation (PHMC), CNKI, and Pubmed, from January 1,2008 to Mar. 1, 2018, using Helicobacter pylori and rosacea to retrieve the literature. Depending on the inclusion and exclusion criteria, 27 articles considered or confirmed the correlation between H. pylori and rosacea. RESULTS Epidemiological investigations and experiments have confirmed that H. pylori infection is associated with the development of rosacea. The effect of anti-H. pylori therapy is better than the routine therapy for rosacea. H. pylori can stimulate the immune system to produce a large number of inflammatory mediators, leading to the occurrence and aggravation of rosacea inflammation. CONCLUSIONS It is confirmed that H. pylori infection is involved in the development of rosacea. It is suggested that rosacea patients should be tested for H. pylori infection, the H. pylori-positive rosacea patients should be treated with eradication of H. pylori, so as to enhance the therapeutic effect of rosacea. This study adds that H. pylori infection is involved in the development of rosacea. Epidemiological investigations and experiments have confirmed the rationality. The effect of anti-H. pylori therapy is better than the routine therapy for rosacea. H. pylori-positive rosacea patients should be treated with the therapeutic method of eradication of H. pylori.

Abstract
Dietary change may play a role in the therapy of rosacea. Certain foods and beverages may act as “triggers” for rosacea exacerbations. These may be divided into heat-related, alcohol-related, capsaicin-related, and cinnamaldehyde-related. One potential pathogenic mechanism may be via the activation of transient receptor potential cation channels, which result in neurogenic vasodilatation. Further research is needed on the role of the gut skin connection in rosacea. Epidemiologic studies suggest that patients with rosacea have a higher prevalence of gastrointestinal disease, and one study reported improvement in rosacea following successful treatment of small intestinal bacterial overgrowth. While further research is required in this area, patients may be advised on measures to support a healthy gut microbiome, including the consumption of a fiber-rich (prebiotic) diet.

Abstract
Rosacea is a common chronic inflammatory disease affecting the facial skin whose etiology and pathophysiology are the subject of much investigation. Risk factors include genetic and environmental elements that may predispose individuals to localized inflammation and abnormal neurovascular responses to stimuli. Recent studies have introduced an array of systemic rosacea comorbidities, such as inflammatory bowel disease and neurologic conditions, that can be challenging to synthesize. We critically review the current data behind reported rosacea comorbidities and identify and highlight underrecognized physiologic mediators shared among rosacea and associated comorbidities. This information may be helpful in addressing patient questions about potential systemic implications of rosacea and can serve as a candidate platform for future research to understand rosacea and improve treatments.

Abstract
BACKGROUND Rosacea is linked to abnormalities of cutaneous vasculature and dysregulation of the inflammatory response. Recent reports on rosacea have shown a significant association with cardiovascular, gastrointestinal, and psychiatric diseases, all of which may affect morbidity and mortality among these patients. OBJECTIVE To review available data regarding comorbidities associated with rosacea, discuss their pathogenesis, and highlight the evaluation of affected patients. METHODS We performed a complete and systematic literature review in PubMed/Medline, Embase, and the Cochrane Collaboration databases, searching for all articles on possible associated diseases that have been reported with rosacea, with no limits on publication date, participant age, sex, or nationality. RESULTS A total of 29 studies were included in this systematic review, including 14 case-control, 8 cross-sectional, and 7 cohort studies. Statistically significant association with rosacea has been mostly demonstrated with depression (n = 117,848 patients), hypertension (n = 18,176), cardiovascular diseases (n = 9739), anxiety disorder (n = 9079), dyslipidemia (n = 7004), diabetes mellitus (n = 6306), migraine (n = 6136), rheumatoid arthritis (n = 4192), Helicobacter pylori infection (n = 1722), ulcerative colitis (n = 1424), and dementia (n = 1194). LIMITATIONS Limitations included the accuracy of the published data, potential patient selection, and possible confounding factors. The true nature of the drawn correlations is uncertain, and causality cannot be established. CONCLUSIONS Rosacea is associated with a number of systemic disorders. Recognition of these conditions is critical to providing appropriate screening and management of affected patients.

Abstract
Rosacea is a chronic skin disease characterized by facial erythema and telangiectasia. Despite the fact that many hypotheses have been proposed, its etiology remains unknown. In the present review, the possible link and clinical significance of Helicobacter pylori in the pathogenesis of rosacea are being sought. A PubMed and Google Scholar search was performed using the terms “rosacea”, “H.pylori”, “gastrointestinal disorders and H.pylori”, “microorganisms and rosacea”, “pathogenesis and treatment of rosacea”, and “risk factors of rosacea”, and selected publications were studied and referenced in text. Although a possible pathogenetic link between H. pylori and rosacea is advocated by many authors, evidence is still interpreted differently by others. We conclude that further studies are needed in order to fully elucidate the pathogenesis of rosacea.

Abstract
BACKGROUND Rosacea is a common skin disease characterized by facial erythema, telangiectasia, papules and pustules. Helicobacter pylori infection has been suggested to play a role in the etiopathogenesis of rosacea. OBJECTIVE To systematically review and meta-analyse the relationship between rosacea and infection with Helicobacter pylori. METHODS A literature search was performed using PubMed, EMBASE and Web of Science. Data extraction and analyses were performed on descriptive data. Study quality was assessed using the Newcastle-Ottawa Scale. Random-effects models with DerSimonian-Laird methods were utilized to estimate pooled odds ratios (ORs), with 95% confidence intervals (95% CIs). Heterogeneity of results was assessed using I² statistics. RESULTS A total of 454 articles were identified and 42 full-text articles were chosen for further review. Fourteen studies were included in the quantitative meta-analysis, comprising a total of 928 rosacea patients and 1527 controls. The overall association between Helicobacter pylori infection and rosacea was non-significant (OR 1.68, 95% CI 1.00-2.84, P = 0.052), but analysis restricted to C-urea breath test showed a significant association (OR 3.12, 95% CI 1.92-5.07, P < 0.0001). Effect of eradication treatment on rosacea symptoms was assessed in seven studies, but without significant effect (RR 1.28, 95% CI 0.98-1.67, P = 0.069). CONCLUSION This meta-analysis found weak associations between rosacea and Helicobacter pylori infection as well as an effect of Helicobacter pylori therapy on rosacea symptoms, albeit that these did not reach statistical significance. Whether a pathogenic link between the two conditions exists, or whether Helicobacter pylori infection represents a proxy for other factors remains unknown.

Abstract
Rosacea is a chronic dermatological disease. Helicobacter pylori has been discussed as one of its causative factors. In this clinical trial study, we attempted to evaluate the effect of H. pylori standard eradication protocol on the rosacea clinical course. In this single-arm clinical trial, patients ascertained to have H. pylori infection based on serological studies were assessed to examine existence of rosacea. Patients with concurrent rosacea and H. pylori infection were included in the study and underwent standard H. pylori eradication therapy. Rosacea was evaluated using the Duluth rosacea grading score at the beginning, 2 months later and at the end of the trial (day 180). Of 872 patients positive for H. pylori, 167 patients (19.15%) manifested the clinical features of rosacea. The patients with concurrent rosacea were younger (P < 0.001) and with a female sex predominance (P = 0.03) when compared with rosacea-free patients. Of 167 patients, 150 received H. pylori eradication therapy, demonstrating a 92% (138/150) cure rate. The rosacea Duluth score grading on day 0, 60 and 180 among 138 patients significantly decreased in most of the criteria except for telangiectasias (P = 0.712), phymatous changes (P = 0.535) and the existence of peripheral involvement (P = 0.431). The present study concluded that H. pylori eradication leads to improvement of rosacea.

Abstract
PURPOSE Chronic Helicobacter pylori gastritis affects two-thirds of the world's population and is one of the most common chronic inflammatory disorders of humans, the infection clearly results in chronic mucosal inflammation in the stomach and duodenum, which, in turn, might lead to abnormalities in gastroduodenal motility and sensitivity and is the most frequent cause of dyspepsia and peptic disease. Some studies showed that there was a correlation between low-grade inflammation as CRP and HP infection. The purpose of this study was to investigate the relationship between the presence of HP infection and platelet/lymphocyte ratio (PLR). METHOD A total of 200 patients who met the HP criteria and 180 age- and gender-matched control subjects were included in this randomized controlled trial. Patients were diagnosed to have HP according stomach biopsy and urea breath test, PLR was calculated from complete blood count at time of diagnosis and before initiating the treatment. RESULTS Patients with HP infection had significantly higher PLR compared to those without HP. Moreover, the patients with symptomatic HP had higher PLR than those with asymptomatic HP. While PLR increased as the severity of HP symptoms increased (r=.452, P<.001). CONCLUSION Our study indicated, for the first time, a significant association between HP infection and symptoms based on PLR, a simple and reliable indicator of inflammation. Furthermore, there an increase in PLR as the severity of HP increases.

Abstract
BACKGROUND Rosacea is a common inflammatory facial skin condition. Recent genetic and epidemiological studies have suggested pathogenic links between rosacea and gastrointestinal disorders, but data are limited. OBJECTIVES The objective was to investigate the association between rosacea and coeliac disease (CeD), Crohn disease (CD), ulcerative colitis (UC), Helicobacter pylori infection (HPI), small intestinal bacterial overgrowth (SIBO) and irritable bowel syndrome (IBS), respectively. METHODS We performed a nationwide cohort study. A total of 49 475 patients with rosacea and 4 312 213 general population controls were identified using nationwide administrative registers. We established the prevalence of the aforementioned disorders, and used Cox regression analysis to obtain hazard ratios (HRs) of the risk of new-onset CeD, CD, UC, HPI, SIBO and IBS, respectively, in patients with rosacea. RESULTS The prevalence of CeD, CD, UC, HPI, SIBO and IBS, respectively, was higher among patients with rosacea when compared with the control subjects. Adjusted HRs revealed significant associations between rosacea and CeD (HR 1·46, 1·11-1·93), CD (HR 1·45, 1·19-1·77), UC (HR 1·19, 1·02-1·39), and IBS (HR 1·34, 1·19-1·50), respectively, but not HPI (HR 1·04, 0·96-1·13) or SIBO (HR 0·71, 0·18-1·86). CONCLUSIONS Rosacea is associated with certain gastrointestinal diseases, but the possible pathogenic link is unknown. Gastrointestinal complaints in patients with rosacea should warrant clinical suspicion of disease.

Abstract
BACKGROUND Rosacea is a common chronic inflammatory disorder affecting facial skin. Currently, no accurate and objective method is available for assessing the severity of rosacea. Most studies use the National Rosacea Society Standard (NRSS) grading method, which lacks objectivity and yields varying results. METHODS Eighteen patients with rosacea were included. Clinical severity was assessed on the basis of the NRSS grade, Investigators' Global Assessment, Patients' Global Assessment, and Dermatology Quality of Life Index. A skin color analysis system was used to measure the facial area showing erythema, and biophysical parameters of facial skin (transepidermal water loss and skin surface hydration) were examined. To find statistical significant in classification severity of the rosacea, statistical analysis was performed with all parameters. RESULTS A significant correlation (P < 0.05) was found between the NRSS grade, facial area showing erythema, and biophysical parameters. The latter two factors differed significantly among patients with rosacea of different levels of severity (mild, moderate, severe; P < 0.05). CONCLUSION Color imaging systems can be useful and reliable for evaluating the severity of rosacea, in addition to biophysical parameter assessment. The combination of these two analytical methods enabled objective and quantitative evaluation of the severity of rosacea.

Abstract
Rosacea is a chronic inflammatory skin condition that affects approximately 16 million Americans. Four distinct subtypes of rosacea have been recognized, with transient and nontransient facial flushing, telangiectasia, and inflammatory papules and pustules being among the more commonly recognized features. Although the exact pathogenesis of rosacea is unknown, dysregulation of the innate immune system, overgrowth of commensal skin organisms, and aberrant neurovascular signaling may all have a role in promoting the clinical features of rosacea.

Abstract
BACKGROUND AND AIMS Recent studies suggest a potential relationship between rosacea and Helicobacter pylori (H. pylori) infection or small intestinal bacterial overgrowth (SIBO), but there is no firm evidence of an association between rosacea and H. pylori infection or SIBO. We performed a prospective study to assess the prevalence of H. pylori infection and/or SIBO in patients with rosacea and evaluated the effect of H. pylori or SIBO eradication on rosacea. METHODS We enrolled 90 patients with rosacea from January 2012 to January 2013 and a control group consisting of 90 patients referred to us because of mapping of nevi during the same period. We used the (13)C Urea Breath Test and H. pylori stool antigen (HpSA) test to assess H. pylori infection and the glucose breath test to assess SIBO. Patients infected by H. pylori were treated with clarithromycin-containing sequential therapy. Patients positive for SIBO were treated with rifaximin. RESULTS We found that 44/90 (48.9%) patients with rosacea and 24/90 (26.7%) control subjects were infected with H. pylori (p = 0.003). Moreover, 9/90 (10%) patients with rosacea and 7/90 (7.8%) subjects in the control group had SIBO (p = 0.6). Within 10 weeks from the end of antibiotic therapy, the skin lesions of rosacea disappeared or decreased markedly in 35/36 (97.2%) patients after eradication of H. pylori and in 3/8 (37.5%) patients who did not eradicate the infection (p < 0.0001). Rosacea skin lesions decreased markedly in 6/7 (85.7%) after eradication of SIBO whereas of the two patients who did not eradicate SIBO, one (50%) showed an improvement in rosacea (p = 0.284). CONCLUSIONS Prevalence of H. pylori infection was significantly higher in patients with rosacea than control group, whereas SIBO prevalence was comparable between the two groups. Eradication of H. pylori infection led to a significant improvement of skin symptoms in rosacea patients.

Abstract
Helicobacter pylori (H. pylori) infection has been clearly linked to peptic ulcer disease and some gastrointestinal malignancies. Increasing evidence demonstrates possible associations to disease states in other organ systems, known as the extraintestinal manifestations of H. pylori. Different conditions associated with H. pylori infection include those from hematologic, cardiopulmonary, metabolic, neurologic, and dermatologic systems. The aim of this article is to provide a concise review of the evidence that supports or refutes the associations of H. pylori and its proposed extraintestinal manifestations. Based on data from the literature, PUD, mucosal associated lymphoid tumors lymphoma, and gastric adenocarcinoma has well-established links. Current evidence most supports extraintestinal manifestations with H. pylori in immune thrombocytopenic purpura, iron deficiency anemia, urticaria, Parkinson’s, migraines and rosacea; however, there is still plausible link with other diseases that requires further research.

Abstract
OBJECTIVE Infection with the bacterial pathogen Helicobacter pylori (HP) clearly results in chronic mucosal inflammation in the stomach and duodenum, which, in turn, might lead to abnormalities in gastroduodenal motility and sensitivity and is the most frequent cause of dyspepsia and peptic disease. Some studies have shown that there was a correlation between low-grade inflammation as C-reactive protein (CRP) and HP infection. The aim of this study was to investigate the relationship between the presence of gastritis due to HP infection and neutrophil/lymphocyte ratio (NLR), a simple and reliable indicator of inflammation. DESIGN Fifty patients met the HP criteria and half of them have had severe symptoms and upper endoscopy showed atrophic gastritis, and fifty age- and sex-matched control subjects with gastritis without HP infection were included in this randomized controlled trial. Patients were diagnosed to have HP according to the use of urea breath testing (UBT) and multiple biopsies. NLR was calculated from complete blood count at the time of diagnosis and before initiating the treatment to all groups. RESULTS Patients with HP infection had significantly higher NLR compared to those without HP. Moreover, the patients with symptomatic HP and grade 4 gastritis had higher NLR than those asymptomatic with past history of peptic disease (P 0.007 and P 0.068, respectively). Although NLR increased as the severity of gastritis and HP symptoms increased (r = 0.564, P < 0.001), Receiver operating characteristic (ROC) Curve analysis was performed. The cut-off level for NLR with optimal sensitivity and specificity was calculated as 1.82 (area under curve [AUC] = 0.825 [0.753-0.884], P < 0.001). CONCLUSION The present study indicated, for the first time, a significant correlation between HP infection and inflammation on the basis of NLR, a simple and reliable indicator of inflammation. Furthermore, there is an increase in NLR as the severity of gastritis with HP increases. This elevated ratio gets normalized with treatment.

Potential role of microorganisms in the pathogenesis of rosacea. J Am Acad Dermatol 2013; 69:1025-32. [PMID: 24011460 DOI: 10.1016/j.jaad.2013.08.006] [Citation(s) in RCA: 84] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Revised: 07/30/2013] [Accepted: 08/02/2013] [Indexed: 02/07/2023]
Abstract
Rosacea is a skin condition of abnormal inflammation and vascular dysfunction. The active contribution of a microbial agent in the development or progression of rosacea continues to be debated. Research supports the presence of commensal Demodex folliculorum mites at increased density in the skin and associates Helicobacter pylori infection of the gut with rosacea. Fewer studies implicate Staphylococcus epidermidis, Chlamydophila pneumoniae, and the Demodex-associated bacteria Bacillus oleronius. No research, however, provides a mechanism by which colonization by a microorganism translates to manifestation of the condition. Prevailing and emerging principles in the biology of the microbiome and the pathophysiology of rosacea may help to reconcile these lingering questions. Here the microorganisms implicated in rosacea are reviewed and the reaction of the microbiome to inflammation and to changes in microenvironments and macroenvironments are discussed to explain potential roles for microorganisms in rosacea pathophysiology.

Abstract
Rosacea is a common and chronic inflammatory skin disease most frequently seen in groups of genetically related individuals. Although the symptoms of rosacea are heterogeneous, they are all related by the presence of characteristic facial or ocular inflammation involving both the vascular and tissue stroma. Until recently, the pathophysiology of this disease was limited to descriptions of a wide variety of factors that exacerbate or improve disease. Recent molecular studies show a common link between the triggers of rosacea and the cellular response, and these observations suggest that an altered innate immune response is involved in disease pathogenesis. Understanding rosacea as a disorder of innate immunity explains the benefits of current treatments and suggests new therapeutic strategies for alleviating this disease.

Future candidates for indications of Helicobacter pylori eradication: do the indications need to be revised? J Gastroenterol Hepatol 2012; 27:200-11.

Abstract
Since the discovery of Helicobacter pylori in 1982, the development of several treatment guidelines has allowed a consensus on the indications for H. pylori eradication. Beyond these currently accepted indications, including various upper gastrointestinal disorders and extragastric diseases, a significant amount of new information regarding H. pylori eradication is emerging. Certain types of acute gastritis, such as nodular gastritis, hypertrophic gastritis, Ménétrier's disease, hemorrhagic gastritis, and granulomatous gastritis are reversible after H. pylori eradication. Further, for chronic gastritis, closed-type atrophic gastritis and complete-type intestinal metaplasia appear to be more reversible after H. pylori eradication than open-type atrophic gastritis and incomplete-type intestinal metaplasia. Eradication can also be considered in subjects younger than 40 years who have a family history of gastric cancer and in subjects with long-term medications that might lead to bleeding (antiplatelet agents) or atrophy (proton pump inhibitors). Emerging evidence indicates that H. pylori eradication could be an effective treatment for some extragastric diseases that are unresponsive to conventional therapy. In such conditions, routine screening for eradication of H. pylori has not previously been recommended; a "test-and-treat" approach is suggested in the aforementioned situations. Given that H. pylori eradication is effective when the gastritis is reversible, future indications should be expanded to include acute gastric lesions that show marked improvement upon H. pylori eradication rather than just focusing on chronic gastric lesions. Future indications for H. pylori eradication should focus more on reversible lesions before preneoplastic conditions develop.

Photodynamic therapy based on 5-aminolevulinic acid and its use as an antimicrobial agent. Med Res Rev 2011; 32:1292-327.

Abstract
Exogenous 5-aminolevulinic acid (ALA) is taken up directly by bacteria, yeasts, fungi, and some parasites, which then induces the accumulation of protoporphyrin IX (PPIX). Subsequent light irradiation of PPIX leads to the inactivation of these organisms via photodamage to their cellular structures. ALA uptake and light irradiation of PPIX produced by host cells leads to the inactivation of other parasites, along with some viruses, via the induction of an immune response. ALA-mediated PPIX production by host cells and light irradiation result in the inactivation of other viruses via either the induction of a host cell response or direct photodynamic attack on viral particles. This ALA-mediated production of light-activated PPIX has been extensively used as a form of photodynamic therapy (PDT) and has shown varying levels of efficacy in treating conditions that are associated with microbial infection, ranging from acne and verrucae to leishmaniasis and onychomycosis. However, for the treatment of some of these conditions by ALA-based PDT, the role of an antimicrobial effect has been disputed and in general, the mechanisms by which the technique inactivates microbes are not well understood. In this study, we review current understanding of the antimicrobial mechanisms used by ALA-based PDT and its role in the treatment of microbial infections along with its potential medical and nonmedical applications.

Abstract
Alopecia areata is a disease of the hair follicles, with strong evidence supporting autoimmune etiology. Alopecia areata is frequently associated with immune-mediated diseases with skin manifestations such as psoriasis and lichen planus, or without skin manifestations such as autoimmune thyroiditis and idiopathic thrombocytopenic purpura. Helicobacter pylori (H. pylori) infection is present in around 50% of the world's population and has been associated with a variety of immune-mediated extra-digestive disorders including autoimmune thyroiditis, idiopathic thrombocytopenic purpura, and psoriasis. A case of a 43-year old man with an 8-mo history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication. If such an association is confirmed by epidemiological studies designed for this purpose, new therapeutic options could be available for these patients, especially in areas where infection with H. pylori is highly prevalent.

Abstract
Rosacea is a chronic inflammatory disease with a predominance of facial manifestations. The prevalence is increasing with age, peaking in the group aged older than 65 years. In 1997, one in eight Americans was aged 65 years and older. By 2030, more than 70 million individuals will be in this age group. This contribution reviews the current understanding of pathogenesis, aggravating factors, classification, comorbidities, and treatment options. Rosacea is a manageable disease that negatively affects quality of life. Rosacea increases the risk of depression and shows a significant proportion of extracutaneous manifestations, in particular ocular rosacea.

Abstract
Helicobacter pylori is a Gram-negative bacterium that is considered a causative agent of peptic ulcer disease, gastric lymphoma, and gastric carcinoma. H pylori triggers an intense leucocyte infiltration of the gastric submucosa, an action that is mediated by proinflammatory cytokines. Because this pathogenetic mechanism is common to many other diseases, H pylori seroprevalence has also been investigated in other diseases. H pylori seropositivity is associated with various dermatologic disorders. Although the precise role of H pylori is unknown in these diseases, the organism can be eradicated, using simple and reliable drug regimens. This contribution highlights the dermatologic diseases associated with H pylori seropositivity.
