Buruli disease (BU) is a progressive necrotic and ulcerative disease of the skin and subcutaneous tissue caused by Mycobacterium ulcerans. BU is considered the third most common mycobacterial disease after tuberculosis and leprosy. Three clinical stages of the cutaneous lesions have been described in BU: pre-ulcerative, ulcerative and healed lesions. In this study we used immunohistochemistry and automated morphometry to determine the percentage of macrophages and of CD4/CD8 lymphocytes and their expression of interferon (IFN)-γ, interleukin (IL)-10, tumour necrosis factor (TNF)-α and transforming growth factor (TGF)-β. Expression of these cytokines was correlated with the inflammatory response evaluated by histopathology. All the studied BU ulcerative cases showed extensive necrosis and chronic inflammation. The most important feature was the presence or absence of granulomas co-existing with a mixed pro-inflammatory/anti-inflammatory cytokine balance. When granulomas were present significantly higher expression of IFN-γ was seen, whereas in ulcerative lesions without granulomas there was increased expression of IL-10 and significantly higher bacillary counts. These features correlated with the chronicity of the lesions; longer-lasting lesions showed granulomas. Thus, granulomas were absent from relatively early ulcerative lesions, which contained more bacilli and little IFN-γ, suggesting that at this stage of the disease strong suppression of the protective cellular immune response facilitates proliferation of bacilli.

Full Text Available Following introduction of antimycobacterial treatment of Buruli ulcer disease (BUD, several clinical studies evaluated treatment outcomes of BUD patients, in particular healing times, secondary lesions and functional limitations. Whereas recurrences were rarely observed, paradoxical reactions and functional limitations frequently occurred. Although systematic BUD control in Togo was established as early as 2007, treatment outcome has not been reviewed to date. Therefore, a pilot project on post-treatment follow-up of BUD patients in Togo aimed to evaluate treatment outcomes and to provide recommendations for optimization of treatment success.Out of 199 laboratory confirmed BUD patients, 129 could be enrolled in the study. The lesions of 109 patients (84.5% were completely healed without any complications, 5 patients (3.9% had secondary lesions and 15 patients (11.6% had functional limitations. Edema, category III ulcers >15 cm, healing times >180 days and a limitation of movement at time of discharge constituted the main risk factors significantly associated with BUD related functional limitations (P180 days and limitation of movement at discharge constituted the main risk factors for functional limitations in Togolese BUD patients. Standardized treatment plans, patient assessment and follow-up, as well as improved management of medical records are recommended to allow for intensified monitoring of disease progression and healing process, to facilitate implementation of therapeutic measures and to optimize treatment success.

The first cases of Buruli ulcer (BU) in Gabon were described in the 1960s. Between 2005 and 2011, 301 clinically suspected cases of BU were found in all nine provinces of Gabon, and their lesions sampled for microbiological confirmation. Polymerase chain reaction (PCR) found 120 (39.9%) of these lesions positive and 181 (60.1%) negative for Mycobacterium ulcerans. The confirmed cases came mainly from the province of Moyen-Ogooué, particularly from localities along the Ogooué River (n=117; 52.5% of the samples in this province were PCR-positive). The detection rates per 100,000 inhabitants in this province ranged from 94.7 cases in 2005 to 28 in 2007, after an absence of active case-finding in 2006. The final three PCR-positive cases were found in the province of Estuaire. The characteristics of the confirmed BU patients (that is, PCR-positive) were identical to those described in other African countries: most patients were younger than 15 years old, and most lesions were found on both the upper and lower limbs. The group of suspected cases (PCR-negative) differed from the PCR-positive group for patient age (most patients were aged 15 to 49 years), lesion location (more frequently on the lower limbs), and ulceration (more frequent in the suspected cases). Some PCR-negative patients probably had other diseases; this underlines the importance of the differential diagnosis of BU. The cure rate of PCR(-)confirmed cases in our study was 88%; treatment was the antibiotic combination recommended by the World Health Organization (WHO). Our study demonstrates that BU is endemic in Gabon and is a public health problem there. Patients consult late with often extensive lesions. Awareness campaigns should be pursued to ensure earlier treatment of patients. The influence of HIV on BU in Gabon also deserves particular attention.

Land cover and its change have been linked to Buruli ulcer (BU), a rapidly emerging tropical disease. However, it is unknown whether landscape structure affects the disease prevalence. To examine the association between landscape pattern and BU presence, we obtained land cover information for 20 villages in southwestern Ghana from high resolution satellite images, and analyzed the landscape pattern surrounding each village. Eight landscape metrics indicated that landscape patterns between BU case and reference villages were different (P landscape fragmentation and diversity indices were positively associated with BU presence in a village. Specifically, for each increase in patch density and edge density by 100 units, the likelihood of BU presence in a village increased 2.51 (95% confidence interval [CI] = 1.36-4.61) and 4.18 (95% CI = 1.63-10.76) times, respectively. The results suggest that increased landscape fragmentation may pose a risk to the emergence of BU.

In 1969, David Barker, his wife and four children moved to Uganda to work at Makerere Medical School in the capital Kampala. During the 1960s, Makerere had become a research and teaching centre with an international reputation based on the work of Trowell, Burkitt, Hutt and many others who had pioneered studies explaining the disease patterns in the West Nile area on the basis of the local climate, nutrition and lifestyle. David Barker was funded by the Medical Research Council to carry out research on a poorly understood disease, Buruli ulcer, joining Scottish surgeon Wilson Carswell, who was later to achieve fame as the role model for Dr Garrigan in Giles Foden's novel The Last King of Scotland.
Full Text Available BACKGROUND: Since the early 1990s more than 1,800 patients with lesions suspicious for Buruli ulcer disease (BUD have been reported from Togo. However, less than five percent of these were laboratory confirmed. Since 2007, the Togolese National Buruli Ulcer Control Program has been supported by the German Leprosy and Tuberculosis Relief Association (DAHW. Collaboration with the Department for Infectious Diseases and Tropical Medicine (DITM, University Hospital, Munich, Germany, allowed IS2404 PCR analysis of diagnostic samples from patients with suspected BUD during a study period of three years. METHODOLOGY/PRINCIPAL FINDINGS: The DAHW integrated active BUD case finding in the existing network of TB/Leprosy Controllers and organized regular training and outreach activities to identify BUD cases at community level. Clinically suspected cases were referred to health facilities for diagnosis and treatment. Microscopy was carried out locally, external quality assurance (EQA at DITM. Diagnostic samples from 202 patients with suspected BUD were shipped to DITM, 109 BUD patients (54% were confirmed by PCR, 43 (29.9% by microscopy. All patients originated from Maritime Region. EQA for microscopy resulted in 62% concordant results. CONCLUSIONS/SIGNIFICANCE: This study presents a retrospective analysis of the first cohort of clinically suspected BUD cases from Togo subjected to systematic laboratory analysis over a period of three years and confirms the prevalence of BUD in Maritime Region. Intensified training in the field of case finding and sample collection increased the PCR case confirmation rate from initially less than 50% to 70%. With a PCR case confirmation rate of 54% for the entire study period the WHO standards (case confirmation rate ≥50% have been met. EQA for microscopy suggests the need for intensified supervision and training. In January 2011 the National Hygiene Institute, Lomé, has assumed the role of a National Reference Laboratory

The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is limited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Numerous studies have associated Buruli ulcer (BU) disease with disturbed aquatic habitats; however, the natural reservoir, distribution, and transmission of the pathogen, Mycobacterium ulcerans, remain unknown. To better understand the role of aquatic plants in the ecology of this disease, a large-scale survey was conducted in waterbodies of variable flow throughout three regions of Ghana, Africa. Our objectives were to characterize plant communities and identify potential relationships with M. ulcerans and other mycolactone-producing mycobacteria (MPM). Waterbodies with M. ulcerans had significantly different aquatic plant communities, with submerged terrestrial plants identified as indicators of M. ulcerans presence. Mycobacterium ulcerans and MPM were detected on 14 plant taxa in emergent zones from both lotic and lentic waterbodies in endemic regions; however, M. ulcerans was not detected in the non-endemic Volta region. These findings support the hypothesis that plants provide substrate for M. ulcerans colonization and could act as potential indicators for disease risk. These findings also suggest that M. ulcerans is a widespread environmental bacteria species, but that it is absent or reduced in regions of low disease incidence. A better understanding is needed regarding the mechanistic associations among aquatic plants and M. ulcerans for identifying the mode of transmission of BU disease.
Full Text Available BACKGROUND: In a previous study PCR analysis of clinical samples from suspected cases of Buruli ulcer disease (BUD from Togo and external quality assurance (EQA for local microscopy were conducted at an external reference laboratory in Germany. The relatively poor performance of local microscopy as well as effort and time associated with shipment of PCR samples necessitated the implementation of stringent EQA measures and availability of local laboratory capacity. This study describes the approach to implementation of a national BUD reference laboratory in Togo. METHODOLOGY: Large scale outreach activities accompanied by regular training programs for health care professionals were conducted in the regions "Maritime" and "Central," standard operating procedures defined all processes in participating laboratories (regional, national and external reference laboratories as well as the interaction between laboratories and partners in the field. Microscopy was conducted at regional level and slides were subjected to EQA at national and external reference laboratories. For PCR analysis, sample pairs were collected and subjected to a dry-reagent-based IS2404-PCR (DRB-PCR at national level and standard IS2404 PCR followed by IS2404 qPCR analysis of negative samples at the external reference laboratory. PRINCIPAL FINDINGS: The inter-laboratory concordance rates for microscopy ranged from 89% to 94%; overall, microscopy confirmed 50% of all suspected BUD cases. The inter-laboratory concordance rate for PCR was 96% with an overall PCR case confirmation rate of 78%. Compared to a previous study, the rate of BUD patients with non-ulcerative lesions increased from 37% to 50%, the mean duration of disease before clinical diagnosis decreased significantly from 182.6 to 82.1 days among patients with ulcerative lesions, and the percentage of category III lesions decreased from 30.3% to 19.2%.

Buruli ulcer (Mycobacterium ulcerans) sees its incidence increase particularly in West Africa. Our Non Governmental Organization (Projet Humanitaire Afrique Nord Sud) studied the distribution of cutaneous ulcer (of which Buruli ulcer) between a flooded site (Bonou) and a dry site (Ketou) in Benin. The ratio "prevalence of Buruli ulcer in our patients of Bonou on prevalence of Buruli ulcer in our patients of Ketou" was 7.5 with a confidence interval at 95% at [1.4 - 41.4]. There is a link between a watery ecosystem and the emergence of Buruli ulcer. Buruli ulcer is overrepresented in the under 15 age group. It can interest all the zones of the tegument whereas the other ulcers concern especially the lower limbs. Thus doctors could not be unaware of the importance of ecological factors ... in precarious medium where diagnosis is based on interrogation, clinical examination and field experience.

Full Text Available BACKGROUND: Mycobacterium ulcerans, the causative agent of Buruli ulcer (BU, is unique among human pathogens in its capacity to produce a polyketide-derived macrolide called mycolactone, making this molecule an attractive candidate target for diagnosis and disease monitoring. Whether mycolactone diffuses from ulcerated lesions in clinically accessible samples and is modulated by antibiotic therapy remained to be established. METHODOLOGY/PRINCIPAL FINDING: Peripheral blood and ulcer exudates were sampled from patients at various stages of antibiotic therapy in Ghana and Ivory Coast. Total lipids were extracted from serum, white cell pellets and ulcer exudates with organic solvents. The presence of mycolactone in these extracts was then analyzed by a recently published, field-friendly method using thin layer chromatography and fluorescence detection. This approach did not allow us to detect mycolactone accurately, because of a high background due to co-extracted human lipids. We thus used a previously established approach based on high performance liquid chromatography coupled to mass spectrometry. By this means, we could identify structurally intact mycolactone in ulcer exudates and serum of patients, and evaluate the impact of antibiotic treatment on the concentration of mycolactone. CONCLUSIONS/SIGNIFICANCE: Our study provides the proof of concept that assays based on mycolactone detection in serum and ulcer exudates can form the basis of BU diagnostic tests. However, the identification of mycolactone required a technology that is not compatible with field conditions and point-of-care assays for mycolactone detection remain to be worked out. Notably, we found mycolactone in ulcer exudates harvested at the end of antibiotic therapy, suggesting that the toxin is eliminated by BU patients at a slow rate. Our results also indicated that mycolactone titres in the serum may reflect a positive response to antibiotics, a possibility that it will be
Full Text Available Buruli ulcer (BU is a slowly progressing, necrotising disease of the skin caused by infection with Mycobacterium ulcerans. Non-ulcerative manifestations are nodules, plaques and oedema, which may progress to ulceration of large parts of the skin. Histopathologically, BU is characterized by coagulative necrosis, fat cell ghosts, epidermal hyperplasia, clusters of extracellular acid fast bacilli (AFB in the subcutaneous tissue and lack of major inflammatory infiltration. The mode of transmission of BU is not clear and there is only limited information on the early pathogenesis of the disease available.For evaluating the potential of the pig as experimental infection model for BU, we infected pigs subcutaneously with different doses of M. ulcerans. The infected skin sites were excised 2.5 or 6.5 weeks after infection and processed for histopathological analysis. With doses of 2 × 10(7 and 2 × 10(6 colony forming units (CFU we observed the development of nodular lesions that subsequently progressed to ulcerative or plaque-like lesions. At lower inoculation doses signs of infection found after 2.5 weeks had spontaneously resolved at 6.5 weeks. The observed macroscopic and histopathological changes closely resembled those found in M. ulcerans disease in humans.Our results demonstrate that the pig can be infected with M. ulcerans. Productive infection leads to the development of lesions that closely resemble human BU lesions. The pig infection model therefore has great potential for studying the early pathogenesis of BU and for the development of new therapeutic and prophylactic interventions.

Background: Buruli ulcer (BU) disease, caused by infection with the environmental mycobacterium M. ulcerans, is an emerging infectious disease in many tropical and sub-tropical countries. Although vectors and modes of transmission remain unknown, it is hypothesized that the transmission of BU disease is associated with human activities in or around aquatic environments, and that characteristics of the landscape (e.g., land use/cover) play a role in mediating BU disease. Several studies performed at relatively small spatial scales (e.g., within a single village or region of a country) support these hypotheses; however, if BU disease is associated with land use/cover characteristics, either through spatial constraints on vector-host dynamics or by mediating human activities, then large-scale (i.e., country-wide) associations should also emerge. The objectives of this study were to (1) investigate associations between BU disease prevalence in villages in Benin, West Africa and surrounding land use/cover patterns and other map-based characteristics, and (2) identify areas with greater and lower than expected prevalence rates (i.e., disease clusters) to assist with the development of prevention and control programs. Results: Our landscape-based models identified low elevation, rural villages surrounded by forest land cover, and located in drainage basins with variable wetness patterns as being associated with higher BU disease prevalence rates. We also identified five spatial disease clusters. Three of the five clusters contained villages with greater than expected prevalence rates and two clusters contained villages with lower than expected prevalence rates. Those villages with greater than expected BU disease prevalence rates spanned a fairly narrow region of south-central Benin. Conclusion: Our analyses suggest that interactions between natural land cover and human alterations to the landscape likely play a role in the dynamics of BU disease. For example

Buruli ulcer, an emerging bacterial disease caused by Mycobacterium ulcerans, affects populations in many equatorial countries, predominantly in western Africa. Occurring in over thirty countries worldwide, it is the third most common Mycobacterial disease after tuberculosis and leprosy. The disease causes ulcerative lesions and can lead to severe deformity if untreated. While methods of treatment for Buruli ulcer are well known and have a high rate of success, the mode of transmission of Buruli ulcer remains elusive. Multiple hypotheses have been put forward in the search for the vector for this disease. Studies of Buruli ulcer to date seem to conclude that water is, in some way, closely related to the transmission of this disease. In particular, changes in water quality due to changes in land use may contribute to the emergence of Buruli ulcer. We hypothesize that stagnant pools, especially those with low dissolved oxygen and high metals, nitrogen, and phosphorus concentrations, will provide a favorable environment for M. ulcerans growth and transmission. To explore how climate, land use, and soil and water quality interact to create a favorable environment for Buruli ulcer emergence, we explore seasonal and annual variability in rainfall and temperature, land use, and physical and chemical properties of soil and water at five sites within the country: four in the southern part of the country (three Buruli-endemic communities and one control) and one non-endemic community in the north. The southern control accounts for differences between endemic and non-endemic communities with similar land uses and geological setting. The northern community has experienced massive floods in recent years, and we suspect that, due to this, Buruli ulcer may start to appear in the community. Results from groundwater data indicate that aquifer rock type does not strongly correlate with groundwater chemistry and that groundwater chemistry does not relate to incidence of Buruli ulcer

Full Text Available BACKGROUND: Cutaneous infection by Mycobacterium ulcerans, also known as Buruli ulcer (BU, represents the third most common mycobacterial disease in the world after tuberculosis and leprosy. Data on the burden of BU disease in the Democratic Republic of Congo are scanty. This study aimed to estimate the prevalence rate and the distribution of BU in the Songololo Territory, and to assess the coverage of the existing hospital-based reporting system. METHODS: We conducted a cross-sectional survey (July-August 2008 using the door-to-door method simultaneously in the two rural health zones (RHZ of the Songololo Territory (RHZ of Kimpese and Nsona-Mpangu, each containing twenty health areas. Cases were defined clinically as active BU and inactive BU in accordance with WHO-case definitions. RESULTS: We detected 775 BU patients (259 active and 516 inactive in a total population of 237,418 inhabitants. The overall prevalence of BU in Songololo Territory was 3.3/1000 inhabitants, varying from 0 to 27.5/1000 between health areas. Of the 259 patients with active BU, 18 (7% had been reported in the hospital-based reporting system at Kimpese in the 6-8 months prior to the survey. CONCLUSION: The survey demonstrated a huge variation of prevalence between health areas in Songololo Territory and gross underreporting of BU cases in the hospital-based reporting system. Data obtained may contribute to better targeted and improved BU control interventions, and serve as a baseline for future assessments of the control program.
Full Text Available As the major burden of Buruli ulcer disease (BUD occurs in remote rural areas, development of point-of-care (POC tests is considered a research priority to bring diagnostic services closer to the patients. Loop-mediated isothermal amplification (LAMP, a simple, robust and cost-effective technology, has been selected as a promising POC test candidate. Three BUD-specific LAMP assays are available to date, but various technical challenges still hamper decentralized application. To overcome the requirement of cold-chains for transport and storage of reagents, the aim of this study was to establish a dry-reagent-based LAMP assay (DRB-LAMP employing lyophilized reagents.Following the design of an IS2404 based conventional LAMP (cLAMP assay suitable to apply lyophilized reagents, a lyophylization protocol for the DRB-LAMP format was developed. Clinical performance of cLAMP was validated through testing of 140 clinical samples from 91 suspected BUD cases by routine assays, i.e. IS2404 dry-reagent-based (DRB PCR, conventional IS2404 PCR (cPCR, IS2404 qPCR, compared to cLAMP. Whereas qPCR rendered an additional 10% of confirmed cases and samples respectively, case confirmation and positivity rates of DRB-PCR or cPCR (64.84% and 56.43%; 100% concordant results in both assays and cLAMP (62.64% and 52.86% were comparable and there was no significant difference between the sensitivity of the assays (DRB PCR and cPCR, 86.76%; cLAMP, 83.82%. Likewise, sensitivity of cLAMP (95.83% and DRB-LAMP (91.67% were comparable as determined on a set of 24 samples tested positive in all routine assays.Both LAMP formats constitute equivalent alternatives to conventional PCR techniques. Provided the envisaged availability of field friendly DNA extraction formats, both assays are suitable for decentralized laboratory confirmation of BUD, whereby DRB-LAMP scores with the additional advantage of not requiring cold-chains. As validation of the assays was conducted in a third

Full Text Available Mycobacterium ulcerans, the causative agent of Buruli ulcer, is an emerging environmental bacterium in Australia and West Africa. The primary risk factor associated with Buruli ulcer is proximity to slow moving water. Environmental constraints for disease are shown by the absence of infection in arid regions of infected countries. A particularly mysterious aspect of Buruli ulcer is the fact that endemic and non-endemic villages may be only a few kilometers apart within the same watershed. Recent studies suggest that aquatic invertebrate species may serve as reservoirs for M. ulcerans, although transmission pathways remain unknown. Systematic studies of the distribution of M. ulcerans in the environment using standard ecological methods have not been reported. Here we present results from the first study based on random sampling of endemic and non-endemic sites. In this study PCR-based methods, along with biofilm collections, have been used to map the presence of M. ulcerans within 26 aquatic sites in Ghana. Results suggest that M. ulcerans is present in both endemic and non-endemic sites and that variable number tandem repeat (VNTR profiling can be used to follow chains of transmission from the environment to humans. Our results suggesting that the distribution of M. ulcerans is far broader than the distribution of human disease is characteristic of environmental pathogens. These findings imply that focal demography, along with patterns of human water contact, may play a major role in transmission of Buruli ulcer.

Neglected tropical diseases (NTDs) have received increasing attention in recent years by the global heath community, as they cumulatively constitute substantial burdens of disease as well as barriers for economic development. A number of common tropical diseases such as malaria, hookworm or schistosomiasis have well-documented economic impacts. However, much less is known about the population-level impacts of diseases that are rare but associated with high disability burden, which represent a great number of tropical diseases. Using an individual-based model of Buruli ulcer (BU), we demonstrate that, through feedbacks between health and economic status, such NTDs can have a significant impact on the economic structure of human populations even at low incidence levels. While average wealth is only marginally affected by BU, the economic conditions of certain subpopulations are impacted sufficiently to create changes in measurable population-level inequality. A reduction of the disability burden caused by BU can thus maximize the economic growth of the poorest subpopulations and reduce significantly the economic inequalities introduced by the disease in endemic regions.

Background Buruli ulcer disease (BUD), caused by Mycobacterium (M.) ulcerans, is the third most common mycobacterial disease after tuberculosis and leprosy. BUD causes necrotic skin lesions and is a significant problem for health care in the affected countries. As for other mycobacterial infections, T cell mediated immune responses are important for protection and recovery during treatment, but detailed studies investigating these immune responses in BUD patients are scarce. In this study, we aimed to characterise M. ulcerans-specific CD4+ T cell responses in BUD patients and to analyse specific cytokine-producing T cells in the context of disease severity and progression. Methodology/Principal findings For this case-control study, whole blood samples of BUD patients (N = 36, 1.5–17 years of age) and healthy contacts (N = 22, 3–15 years of age) were stimulated with antigen prepared from M. ulcerans and CD4+ T cells were analysed for the expression of TNFα, IFNγ and CD40L by flow cytometry. The proportions and profile of cytokine producing CD4+ T cells was compared between the two study groups and correlated with disease progression and severity. Proportions of cytokine double-positive IFNγ+TNFα+, TNFα+CD40L+, IFNγ+CD40L+ (p = 0.014, p = 0.010, p = 0.002, respectively) and triple positive IFNγ+TNFα+CD40L+ (p = 0.010) producing CD4+ T cell subsets were increased in BUD patients. In addition, TNFα+CD40L-IFNγ- CD4+ T cells differed between patients and controls (p = 0.034). TNFα+CD40L-IFNγ- CD4+ T cells were correlated with lesion size (p = 0.010) and proportion were higher in ‘slow’ healers compared to ‘fast healers’ (p = 0.030). Conclusions We were able to identify M. ulcerans-specific CD4+ T cell subsets with specific cytokine profiles. In particular a CD4+ T cell subset, producing TNFα but not IFNγ and CD40L, showed association with lesion size and healing progress. Further studies are required to investigate, if the identified CD4+ T cell
Full Text Available BACKGROUND: Buruli ulcer is an infectious disease involving the skin, caused by Mycobacterium ulcerans. This disease is associated with areas where the water is slow-flowing or stagnant. However, the exact mechanism of transmission of the bacillus and the development of the disease through human activities is unknown. METHODOLOGY/PRINCIPAL FINDINGS: A case-control study to identify Buruli ulcer risk factors in Cameroon compared case-patients with community-matched controls on one hand and family-matched controls on the other hand. Risk factors identified by the community-matched study (including 163 pairs were: having a low level of education, swamp wading, wearing short, lower-body clothing while farming, living near a cocoa plantation or woods, using adhesive bandages when hurt, and using mosquito coils. Protective factors were: using bed nets, washing clothes, and using leaves as traditional treatment or rubbing alcohol when hurt. The family-matched study (including 118 pairs corroborated the significance of education level, use of bed nets, and treatment with leaves. CONCLUSIONS/SIGNIFICANCE: Covering limbs during farming activities is confirmed as a protective factor guarding against Buruli ulcer disease, but newly identified factors including wound treatment and use of bed nets may provide new insight into the unknown mode of transmission of M. ulcerans or the development of the disease.

Full Text Available BACKGROUND: Victims of Buruli ulcer disease (BUD frequently report to specialized units at a late stage of the disease. This delay has been associated with local beliefs and a preference for traditional healing linked to a reportedly mystical origin of the disease. We assessed the role beliefs play in determining BUD sufferers' choice between traditional and biomedical treatments. METHODS: Anthropological fieldwork was conducted in community and clinical settings in the region of Ayos and Akonolinga in Central Cameroon. The research design consisted of a mixed methods study, triangulating a qualitative strand based on ethnographic research and quantitative data obtained through a survey presented to all patients at the Ayos and Akonolinga hospitals (N = 79 at the time of study and in four endemic communities (N = 73 belonging to the hospitals' catchment area. RESULTS: The analysis of BUD sufferers' health-seeking behaviour showed extremely complex therapeutic itineraries, including various attempts and failures both in the biomedical and traditional fields. Contrary to expectations, nearly half of all hospital patients attributed their illness to mystical causes, while traditional healers admitted patients they perceived to be infected by natural causes. Moreover, both patients in hospitals and in communities often combined elements of both types of treatments. Ultimately, perceptions regarding the effectiveness of the treatment, the option for local treatment as a cost prevention strategy and the characteristics of the doctor-patient relationship were more determinant for treatment choice than beliefs. DISCUSSION: The ascription of delay and treatment choice to beliefs constitutes an over-simplification of BUD health-seeking behaviour and places the responsibility directly on the shoulders of BUD sufferers while potentially neglecting other structural elements. While more efficacious treatment in the biomedical sector is likely to

Full Text Available Buruli ulcer (BU is described as a relatively painless condition; however clinical observations reveal that patients do experience pain during their treatment. Knowledge on current pain assessment and treatment in BU is necessary to develop and implement a future guideline on pain management in BU.A mixed methods approach was used, consisting of information retrieved from medical records on prescribed pain medication from Ghana and Benin, and semi-structured interviews with health care personnel (HCP from Ghana on pain perceptions, assessment and treatment. Medical records (n = 149 of patients treated between 2008 and 2012 were collected between November 2012 and August 2013. Interviews (n = 11 were audio-taped, transcribed verbatim and qualitatively analyzed.In 113 (84% of the 135 included records, pain medication, mostly simple analgesics, was prescribed. In 48% of the prescriptions, an indication was not documented. HCP reported that advanced BU could be painful, especially after wound care and after a skin graft. They reported not be trained in the assessment of mild pain. Pain recognition was perceived as difficult, as patients were said to suppress or to exaggerate pain, and to have different expectations regarding acceptable pain levels. HCP reported a fear of side effects of pain medication, shortage and irregularities in the supply of pain medication, and time constraints among medical doctors for pain management.Professionals perceived BU disease as potentially painful, and predominantly focused on severe pain. Our study suggests that pain in BU deserves attention and should be integrated in current treatment.

Full Text Available The only available vaccine that could be potentially beneficial against mycobacterial diseases contains live attenuated bovine tuberculosis bacillus (Mycobacterium bovis also called Bacillus Calmette-Guérin (BCG. Even though the BCG vaccine is still widely used, results on its effectiveness in preventing mycobacterial diseases are partially contradictory, especially regarding Buruli Ulcer Disease (BUD. The aim of this case-control study is to evaluate the possible protective effect of BCG vaccination on BUD.The present study was performed in three different countries and sites where BUD is endemic: in the Democratic Republic of the Congo, Ghana, and Togo from 2010 through 2013. The large study population was comprised of 401 cases with laboratory confirmed BUD and 826 controls, mostly family members or neighbors.After stratification by the three countries, two sexes and four age groups, no significant correlation was found between the presence of BCG scar and BUD status of individuals. Multivariate analysis has shown that the independent variables country (p = 0.31, sex (p = 0.24, age (p = 0.96, and presence of a BCG scar (p = 0.07 did not significantly influence the development of BUD category I or category II/III. Furthermore, the status of BCG vaccination was also not significantly related to duration of BUD or time to healing of lesions.In our study, we did not observe significant evidence of a protective effect of routine BCG vaccination on the risk of developing either BUD or severe forms of BUD. Since accurate data on BCG strains used in these three countries were not available, no final conclusion can be drawn on the effectiveness of BCG strain in protecting against BUD. As has been suggested for tuberculosis and leprosy, well-designed prospective studies on different existing BCG vaccine strains are needed also for BUD.

Full Text Available Abstract Background Mycobacterium ulcerans is an unusual bacterial pathogen with elusive origins. While closely related to the aquatic dwelling M. marinum, M. ulcerans has evolved the ability to produce the immunosuppressive polyketide toxin mycolactone and cause the neglected tropical disease Buruli ulcer. Other mycolactone-producing mycobacteria (MPM have been identified in fish and frogs and given distinct species designations (M. pseudoshottsii, M. shinshuense, M. liflandii and M. marinum, however the evolution of M. ulcerans and its relationship to other MPM has not been defined. Here we report the comparative analysis of whole genome sequences from 30 MPM and five M. marinum. Results A high-resolution phylogeny based on genome-wide single nucleotide polymorphisms (SNPs showed that M. ulcerans and all other MPM represent a single clonal group that evolved from a common M. marinum progenitor. The emergence of the MPM was driven by the acquisition of the pMUM plasmid encoding genes for the biosynthesis of mycolactones. This change was accompanied by the loss of at least 185 genes, with a significant overrepresentation of genes associated with cell wall functions. Cell wall associated genes also showed evidence of substantial adaptive selection, suggesting cell wall remodeling has been critical for the survival of MPM. Fine-grain analysis of the MPM complex revealed at least three distinct lineages, one of which comprised a highly clonal group, responsible for Buruli ulcer in Africa and Australia. This indicates relatively recent transfer of M. ulcerans between these continents, which represent the vast majority of the global Buruli ulcer burden. Our data provide SNPs and gene sequences that can differentiate M. ulcerans lineages, suitable for use in the diagnosis and surveillance of Buruli ulcer. Conclusions M. ulcerans and all mycolactone-producing mycobacteria are specialized variants of a common Mycobacterium marinum progenitor that have

Full Text Available The role of biofilms in the pathogenesis of mycobacterial diseases remains largely unknown. Mycobacterium ulcerans, the etiological agent of Buruli ulcer, a disfiguring disease in humans, adopts a biofilm-like structure in vitro and in vivo, displaying an abundant extracellular matrix (ECM that harbors vesicles. The composition and structure of the ECM differs from that of the classical matrix found in other bacterial biofilms. More than 80 proteins are present within this extracellular compartment and appear to be involved in stress responses, respiration, and intermediary metabolism. In addition to a large amount of carbohydrates and lipids, ECM is the reservoir of the polyketide toxin mycolactone, the sole virulence factor of M. ulcerans identified to date, and purified vesicles extracted from ECM are highly cytotoxic. ECM confers to the mycobacterium increased resistance to antimicrobial agents, and enhances colonization of insect vectors and mammalian hosts. The results of this study support a model whereby biofilm changes confer selective advantages to M. ulcerans in colonizing various ecological niches successfully, with repercussions for Buruli ulcer pathogenesis.

The transmission of Buruli ulcer (BU), caused by Mycobacterium ulcerans (MU), remains puzzling although a number of hypothesis including through bites of infected aquatic insects have been proposed. We report the results of experiments using ICR mice that give credence to our hypothesis that Acanthamoeba species may play a role in BU transmission. We cocultured MU N2 and MU 1615 which expresses red fluorescent protein (RFP) and Acanthamoeba polyphaga (AP), and confirmed infected AP by Ziehl-Neelsen (ZN) staining. We tested for viability of MU inside AP and observed strong RFP signals inside both trophozoites and cysts after 3 and 42 days of coculturing respectively. ICR mice were topically treated, either on shaved intact or shaved pinpricked rumps, with one of the following; MU N2 only (2.25 x 106 colony forming units [CFU] / ml), MU N2:AP coculture (2.96 x 104 CFU: 1.6 x 106 cells/ml), AP only (1.6 x 106 cells/ml), PYG medium and sterile distilled water. Both MU N2 only and MU N2:AP elicited reddening on day (D) 31; edema on D 45 and D 44 respectively, and ulcers on D 49 at pinpricked sites only. To ascertain infectivity and pathogenicity of MU N2 only and MU N2:AP, and compare their virulence, the standard mouse footpad inoculation method was used. MU N2:AP elicited reddening in footpads by D 3 compared to D 14 with MU N2 only of the same dose of MU N2 (2.96 x 104 CFU). ZN-stained MU were observed in both thin sectioned and homogenized lesions, and aspirates from infected sites. Viable MU N2 were recovered from cultures of the homogenates and aspirates. This study demonstrates in ICR mice MU transmission via passive infection, and shows that punctures in the skin are prerequisite for infection, and that coculturing of MU with AP enhances pathogenesis.

Buruli ulcer or Mycobacterium ulcerans disease occurs mainly in areas in proximity to standing or slowly running freshwater, habitats in which free-living amoebae occur. For this reason, a possible link between the habitat of M. ulcerans and free-living amoebae was investigated. Free-living amoebae and mycobacteria were isolated from water and biofilm specimens taken from protected and unprotected sources of water in villages known to have either high or low endemicity for Buruli ulcer in Benin. Amoebae were isolated from 78.8% of samples. A greater proportion of water bodies in areas of high endemicity had amoebae than in areas of low endemicity (83.3% versus 66.7%). Protected sources of water were significantly more likely to contain amoebae in areas of high endemicity than in areas of low endemicity (88.0% versus 11.1%). Several pathogenic free-living amoebae and mycobacteria were isolated. However, no M. ulcerans was isolated and no specimen was positive for IS2404 PCR. Our results show that the study area has a water hygiene problem, which is greater in areas of high Buruli ulcer endemicity than in areas of low endemicity. Our observations indicate that additional studies are required to explore the possible link between free-living amoebae and mycobacteria.

Full Text Available Abstract Background Buruli ulcer is considered a re-emerging disease in West Africa where it has suffered neglect over the years, though children below the age of 16 years are the worst affected in most endemic regions. Due to delayed health seeking, the disease leads to disabilities resulting from amputation and loss of vital organs like the eye leading to school dropout and other social and economic consequences for the affected family. Early treatment with antibiotics is effective; however, this involves daily oral and intramuscular injection at distant health facilities for 56 days making it a challenge among poor rural folks living on daily subsistence work. The mode of transmission of Buruli ulcer is not known and there is no effective preventive vaccine for Buruli ulcer. Thus the only effective control tool is early case detection and treatment to reduce morbidity and associated disabilities that occurs as a result of late treatment. It is therefore essential to implement interventions that remove impediments that limit early case detection; access to early effective treatment and this paper reports one such effort where the feasibility of social interventions to enhance Buruli ulcer control was assessed. Methods This was a qualitative study using in-depth interviews to generate information to ascertain the benefit or otherwise of the intervention implemented. Clinical records of patients to generate data to determine the feasibility and effectiveness of social interventions in the fight against Buruli ulcer was examined. In all, 56 in-depth interviews (28 at baseline and 28 at evaluation were conducted for this report. Results At full implementation, treatment default and dropout reduced significantly from 58.8% and 52.9% at baseline to 1.5% and 1.5% respectively. The number of early case detection went up significantly. Affected families were happy with social interventions such as provision of transportation and breakfast to patients

Successfully addressing neglected tropical diseases requires nuanced understandings of pathogenic landscapes that incorporate situated, contexualized community knowledge. In the case of Buruli ulcer (BU), the role of social science is vital to investigate complex human-environment interactions and navigate different ways of knowing. We analyze a set of qualitative data from our interdisciplinary project on BU in Ghana, drawing from participatory mapping, focus group discussions, semi-structured interviews, and open-ended survey questions to explore how people in endemic and non-endemic areas see themselves embedded in changing environmental and social landscapes. We pay particular attention to landscape disturbance through logging and small-scale alluvial gold mining. The results from our participatory research underscore the holistic nature of BU emergence in landscapes, encapsulated in partial and incomplete local descriptions, the relevance of collective learning to distill complexity, and the potential of rich qualitative data to inform quantitative landscape-disease models.

Full Text Available BACKGROUND: Mycobacterium ulcerans disease (Buruli ulcer is the most widespread mycobacterial disease in the world after leprosy and tuberculosis. How M. ulcerans is introduced into the skin of humans remains unclear, but it appears that individuals living in the same environment may have different susceptibilities. OBJECTIVES: This study aims to determine whether frequent contacts with natural water sources, family relationship or the practice of consanguineous marriages are associated with the occurrence of Buruli ulcer (BU. DESIGN: Case control study. SETTING: Department of Atlantique, Benin. SUBJECTS: BU-confirmed cases that were diagnosed and followed up at the BU detection and treatment center (CDTUB of Allada (Department of the Atlantique, Benin during the period from January 1st, 2006, to June 30th, 2008, with three matched controls (persons who had no signs or symptoms of active or inactive BU for age, gender and village of residence per case. MAIN OUTCOMES MEASURED: Contact with natural water sources, BU history in the family and the practice of consanguineous marriages. RESULTS: A total of 416 participants were included in this study, including 104 cases and 312 controls. BU history in the family (p<0.001, adjusted by daily contact with a natural water source (p = 0.007, was significantly associated with higher odds of having BU (OR; 95% CI = 5.5; 3.0-10.0. The practice of consanguineous marriage was not associated with the occurrence of BU (p = 0.40. Mendelian disorders could explain this finding, which may influence individual susceptibility by impairing immunity. CONCLUSION: This study suggests that a combination of genetic factors and behavioral risk factors may increase the susceptibility for developing BU.

Full Text Available Abstract Background Ghana is a Buruli ulcer (BU endemic country yet there is paucity of socio-cultural research on BU. Examining distinctive experiences and meanings for pre-ulcers and ulcers of BU may clarify the disease burden, illness experience and local perceptions of causes and spread, and environmental features of BU, which are useful to guide public health programmes and future research. This study aimed to explain local meanings and experiences of BU for persons with pre-ulcers and ulcers in the Ga-West and Ga-South municipalities in Accra. Methods Semi-structured interviews based on the Explanatory Model Interview Catalogue framework were administered to 181 respondents comprising 15 respondents with pre-ulcers and 166 respondents with ulcers. The Wilcoxon rank-sum test was used to compare categories of illness experiences (PD and perceived causes (PC among respondents with pre-ulcer and ulcer conditions. The Fisher’s exact test was used to compare the most troubling PD and the most important PC variables. Qualitative phenomenological analysis of respondents’ narratives clarified illness experiences and meanings with reference to PC and PD variables. Results Families of respondents with pre-ulcers and the respondents themselves were often anxious about disease progression, while families of respondents with ulcers, who had to give care, worried about income loss and disruption of school attendance. Respondents with pre-ulcers frequently reported swimming in ponds and rivers as a perceived cause and considered it as the most important PC (53.3%. Respondents with ulcers frequently attributed their BU illness to witchcraft (64.5% and respondents who claimed they had no water contact, questioned the credibility of health messages Conclusions Affected persons with pre-ulcers are likely to delay treatment because of social and financial constraints and the absence of pain. Scepticism on the role of water in disease contagion and
Full Text Available Increased availability of Next Generation Sequencing (NGS techniques allows, for the first time, to distinguish relapses from reinfections in patients with multiple Buruli ulcer (BU episodes.We compared the number and location of single nucleotide polymorphisms (SNPs identified by genomic screening between four pairs of Mycobacterium ulcerans isolates collected at the time of first diagnosis and at recurrence, derived from a collection of almost 5000 well characterized clinical samples from one BU treatment center in Benin.The findings suggest that after surgical treatment-without antibiotics-the second episodes were due to relapse rather than reinfection. Since specific antibiotics were introduced for the treatment of BU, the one patient with a culture available from both disease episodes had M. ulcerans isolates with a genomic distance of 20 SNPs, suggesting the patient was most likely reinfected rather than having a relapse.To our knowledge, this study is the first to study recurrences in M. ulcerans using NGS, and to identify exogenous reinfection as causing a recurrence of BU. The occurrence of reinfection highlights the contribution of ongoing exposure to M. ulcerans to disease recurrence, and has implications for vaccine development.
Full Text Available Buruli ulcer (BU is a necrotizing skin disease caused by Mycobacterium ulcerans. People living in remote areas in tropical Sub Saharan Africa are mostly affected. Wound care is an important component of BU management; this often needs to be extended for months after the initial antibiotic treatment. BU is reported in the literature as being painless, however clinical observations revealed that some patients experienced pain during wound care. This was the first study on pain intensity during and after wound care in BU patients and factors associated with pain. In Ghana and Benin, 52 BU patients above 5 years of age and their relatives were included between December 2012 and May 2014. Information on pain intensity during and after wound care was obtained during two consecutive weeks using the Wong-Baker Pain Scale. Median pain intensity during wound care was in the lower range (Mdn = 2, CV = 1, but severe pain (score > 6 was reported in nearly 30% of the patients. Nevertheless, only one patient received pain medication. Pain declined over time to low scores 2 hours after treatment. Factors associated with higher self-reported pain scores were; male gender, fear prior to treatment, pain during the night prior to treatment, and pain caused by cleaning the wound. The general idea that BU is painless is incorrect for the wound care procedure. This procedural pain deserves attention and appropriate intervention.

Full Text Available Buruli ulcer (BU, a neglected tropical disease of the skin and subcutaneous tissue, is caused by Mycobacterium ulcerans and is the third most common mycobacterial disease after tuberculosis and leprosy. While there is a strong association of the occurrence of the disease with stagnant or slow flowing water bodies, the exact mode of transmission of BU is not clear. M. ulcerans has emerged from the environmental fish pathogen M. marinum by acquisition of a virulence plasmid encoding the enzymes required for the production of the cytotoxic macrolide toxin mycolactone, which is a key factor in the pathogenesis of BU. Comparative genomic studies have further shown extensive pseudogene formation and downsizing of the M. ulcerans genome, indicative for an adaptation to a more stable ecological niche. This has raised the question whether this pathogen is still present in water-associated environmental reservoirs. Here we show persistence of M. ulcerans specific DNA sequences over a period of more than two years at a water contact location of BU patients in an endemic village of Cameroon. At defined positions in a shallow water hole used by the villagers for washing and bathing, detritus remained consistently positive for M. ulcerans DNA. The observed mean real-time PCR Ct difference of 1.45 between the insertion sequences IS2606 and IS2404 indicated that lineage 3 M. ulcerans, which cause human disease, persisted in this environment after successful treatment of all local patients. Underwater decaying organic matter may therefore represent a reservoir of M. ulcerans for direct infection of skin lesions or vector-associated transmission.

Furthermore, we collected 13 water, 90 biofilm and 45 detritus samples in both Buruli ulcer endemic and non-endemic communities in Ghana, from which we cultivated amoeboid protozoa and mycobacteria. M. ulcerans was not isolated, but other mycobacteria were as frequently isolated from intracellular as from extracellular sources, suggesting that they commonly infect amoebae in nature. We screened the samples as well as the amoeba cultures for the M. ulcerans markers IS2404, IS2606 and KR-B. IS2404 was detected in 2% of the environmental samples and in 4% of the amoeba cultures. The IS2404 positive amoeba cultures included up to 5 different protozoan species, and originated both from Buruli ulcer endemic and non-endemic communities. CONCLUSIONS/SIGNIFICANCE: This is the first report of experimental infection of amoebae with M. ulcerans and of the detection of the marker IS2404 in amoeba cultures isolated from the environment. We conclude that amoeba are potential natural hosts for M. ulcerans, yet remain sceptical about their implication in the transmission of M. ulcerans to humans and their importance in the epidemiology of Buruli ulcer.

Full Text Available BACKGROUND: Buruli ulcer (BU, caused by Mycobacterium ulcerans infection, is a debilitating disease of the skin and underlying tissue. The first phase of a BU prevention and treatment programme (BUPaT was initiated from 2005-2008, in the Ga-West and Ga-South municipalities in Ghana to increase access to BU treatment and to improve early case detection and case management. This paper assesses achievements of the BUPaT programme and lessons learnt. It also considers the impact of the programme on broader interests of the health system. METHODS: A mixed-methods approach included patients' records review, review of programme reports, a stakeholder forum, key informant interviews, focus group discussions, clinic visits and observations. PRINCIPAL FINDINGS: Extensive collaboration existed across all levels, (national, municipality, and community, thus strengthening the health system. The programme enhanced capacities of all stakeholders in various aspects of health services delivery and demonstrated the importance of health education and community-based surveillance to create awareness and encourage early treatment. A patient database was also created using recommended World Health Organisation (WHO forms which showed that 297 patients were treated from 2005-2008. The proportion of patients requiring only antibiotic treatment, introduced in the course of the programme, was highest in the last year (35.4% in the first, 23.5% in the second and 42.5% in the third year. Early antibiotic treatment prevented recurrences which was consistent with programme aims. CONCLUSIONS: To improve early case management of BU, strengthening existing clinics to increase access to antibiotic therapy is critical. Intensifying health education and surveillance would ultimately increase early reporting and treatment for all cases. Further research is needed to explain the role of environmental factors for BU contagion. Programme strategies reported in our study: collaboration

A mathematical model was developed and validated to predict the thermal behaviour of a heat application device based on a phase change material (pcm) for the heat treatment of Mycobacterium ulcerans infection (Buruli ulcer). The thermal model allows the prediction of skin surface temperatures and an optimization of the amount of pcm with respect to discharge time. A first prototype of such a pcm bandage was manufactured and used in a proof-of-principal trial in Cameroon. The experimental data were analysed and yielded no difference in thermoregulatory response between people living in hot or moderate climate. Short-term maximum skin surface temperatures of 42 degrees C are tolerable; the pcm bandage keeps the skin surface temperature above 40 degrees C for about four to five hours. This makes such pcm bandages an ideal device for the heat treatment of Buruli ulcer. The pcm bandage is easy to apply, cheap, and thus is well suited for use in low-resource countries.
Full Text Available A comprehensive analysis was done to evaluate the potential use of anti-parasitic macrocyclic lactones (including avermectins and milbemycins for Buruli ulcer (BU therapy. A panel containing nearly all macrocyclic lactones used in human or in veterinary medicine was analyzed for activity in vitro against clinical isolates of Mycobacterium ulcerans. Milbemycin oxime and selamectin were the most active drugs against M. ulcerans with MIC values from 2 to 8 μg/mL and 2 to 4 μg/mL, respectively. In contrast, ivermectin and moxidectin, which are both in clinical use, showed no significant activity (MIC> 32 μg/mL. Time-kill kinetic assays showed bactericidal activity of selamectin and in vitro pharmacodynamic studies demonstrated exposure-dependent activity. These data together with analyses of published pharmacokinetic information strongly suggest that selamectin is the most promising macrocyclic lactone for BU treatment.

Mycobacterium ulcerans, the etiological agent of Buruli ulcer, causes extensive skin lesions, which despite their severity are not accompanied by pain. It was previously thought that this remarkable analgesia is ensured by direct nerve cell destruction. We demonstrate here that M. ulcerans-induced hypoesthesia is instead achieved through a specific neurological pathway triggered by the secreted mycobacterial polyketide mycolactone. We decipher this pathway at the molecular level, showing that mycolactone elicits signaling through type 2 angiotensin II receptors (AT2Rs), leading to potassium-dependent hyperpolarization of neurons. We further validate the physiological relevance of this mechanism with in vivo studies of pain sensitivity in mice infected with M. ulcerans, following the disruption of the identified pathway. Our findings shed new light on molecular mechanisms evolved by natural systems for the induction of very effective analgesia, opening up the prospect of new families of analgesics derived from such systems.

Full Text Available Buruli ulcer (BU is a skin infection caused by Mycobacterium ulcerans. The wounds of most BU patients are colonized with different microorganisms, including Staphylococcus aureus.This study investigated possible patient-to-patient transmission events of S. aureus during wound care in a health care center. S. aureus isolates from different BU patients with overlapping visits to the clinic were whole-genome sequenced and analyzed by a gene-by-gene approach using SeqSphere(+ software. In addition, sequence data were screened for the presence of genes that conferred antibiotic resistance.SeqSphere(+ analysis of whole-genome sequence data confirmed transmission of methicillin resistant S. aureus (MRSA and methicillin susceptible S. aureus among patients that took place during wound care. Interestingly, our sequence data show that the investigated MRSA isolates carry a novel allele of the fexB gene conferring chloramphenicol resistance, which had thus far not been observed in S. aureus.

Buruli ulcer disease (BUD), a devastating tropical disease caused by Mycobacterium ulcerans, occurs in more than 80% of the administrative districts of Ghana. To elucidate community perceptions and understanding of the aetiology of BUD, attitudes towards Buruli patients and treatment-seeking behaviours, we conducted a survey with 504 heads of households and seven focus group discussions in Ga West District, Ghana. Although 67% of participants regarded BUD as a health problem, 53% did not know its cause. Sixteen per cent attributed the cause to drinking non-potable water, 8.1% mentioned poor personal hygiene or dirty surroundings, and 5.5% identified swimming or wading in ponds as a risk factor. About 5.2% thought that witchcraft and curses cause BUD, and 71.8% indicated that BU sufferers first seek treatment from herbalists and only refer to the hospital as a last resort. The main reasons were prospects of prolonged hospital stay, cost of transport, loss of earnings and opportunity associated with parents attending their children's hospitalization over extended period, delays in being attended by medical staff, and not knowing the cause of the disease or required treatment. The level of acceptance of BUD sufferers was high in adults but less so in children. The challenge facing health workers is to break the vicious cycle of poor medical outcomes leading to poor attitudes to hospital treatment in the community. Because herbalists are often the first people consulted by those who contract the disease, they need to be trained in early recognition of the pre-ulcerative stage of Buruli lesions.

The "One World One Health Initiative" has attended little to the priorities, concepts and practices of resource-poor communities confronting disease and the implications of these concerns for its biomedical, ecological and institutional approach to disease surveillance and control. Using the example of Buruli ulcer (BU) and its bacterial etiology, Mycobacterium ulcerans, in south-central Cameroon, we build on debates about the contributions of "local knowledge" and "alternative models" to biomedical knowledge of disease transmission. BU's mode of transmission remains poorly understood. Our approach employs ethno-ecological histories - local understandings of the putative emergence and expansion of a locally important, neglected disease. We develop these histories from 52 individual and small group interviews, group discussions, and participant-observation of daily and seasonal activities, conducted in 2013-2013. These histories offer important clues about past environmental and social change that should guide further ecological, epidemiological research. They highlight a key historical moment (the late 1980s and 1990s); specific ecological transformations; new cultivation practices in unexploited zones that potentially increased exposure to M. ulcerans; and ecological degradation that may have lowered nutritional standards and heightened susceptibility to BU. They also recast transmission, broadening insight into BU and its local analog, atom, by emphasizing the role of social change and economic crisis in its emergence and expansion.
Full Text Available BACKGROUND: Buruli ulcer (BU is an infection of the subcutaneous tissue leading to chronic necrotizing skin ulcers. The causative pathogen, Mycobacterium ulcerans, grows best at 30 degrees C-33 degrees C and not above 37 degrees C. We explored the safety, tolerability and efficacy of phase change material (PCM, a novel heat application system for thermotherapy of BU. METHODOLOGY/PRINCIPAL FINDINGS: In a prospective observational single centre proof-of-principle trial in Ayos/Cameroon, six laboratory reconfirmed patients with ulcerative Buruli lesions received 28-31 (ulcers 2 cm days of thermotherapy with the PCM sodium acetate trihydrate as heat application system. This PCM is widely used in commercial pocket heat pads, it is easy to apply, rechargeable in hot water, non-toxic and non-hazardous to the environment. All patients enrolled in the trial completed treatment. Being completely mobile during the well-tolerated heat application, acceptability of the PCM bandages was very high. In patients with smaller ulcers, wounds healed completely without further intervention. Patients with large defects had skin grafting after successful heat treatment. Heat treatment was not associated with marked increases in local inflammation or the development of ectopic lymphoid tissue. One and a half years after completion of treatment, all patients are relapse-free. CONCLUSIONS/SIGNIFICANCE: Our reusable PCM-based heat application device appears perfectly suited to treat BU in endemic countries with limited resources and infrastructure.

Full Text Available Buruli ulcer (BU is an emerging necrotizing disease of the skin and subcutaneous tissue caused by Mycobacterium ulcerans. While proximity to stagnant or slow flowing water bodies is a risk factor for acquiring BU, the epidemiology and mode of M. ulcerans transmission is poorly understood. Here we have used high-throughput DNA sequencing and comparisons of the genomes of seven M. ulcerans isolates that appeared monomorphic by existing typing methods. We identified a limited number of single nucleotide polymorphisms (SNPs and developed a real-time PCR SNP typing method based on these differences. We then investigated clinical isolates of M. ulcerans on which we had detailed information concerning patient location and time of diagnosis. Within the Densu river basin of Ghana we observed dominance of one clonal complex and local clustering of some of the variants belonging to this complex. These results reveal focal transmission and demonstrate, that micro-epidemiological analyses by SNP typing has great potential to help us understand how M. ulcerans is transmitted.

Full Text Available It has recently been shown that in a Buruli ulcer (BU endemic region of southeastern Australia, significant numbers of possums (native tree-dwelling marsupials have clinical BU disease. Furthermore, based on quantitative PCR (qPCR analysis, animals with BU lesions (and some without shed M. ulcerans DNA in their faeces, indicative of bacterial loads of up to 10(8 organisms/gram. These findings led us to propose that humans might also harbour M. ulcerans in their gastrointestinal tract and shed the bacterium in their faeces. We conducted a pilot study and collected faecal swabs from 26 patients with confirmed BU and 31 healthy household controls. Faecal samples were also collected from 10 healthy controls from non-endemic regions in Ghana. All 67 specimens were negative when tested by IS2404 PCR. The detection sensitivity of this method was ≥10(4 bacteria per gram (wet-weight of human faecal material. We conclude that the human gastrointestinal tract is unlikely to be a significant reservoir of M. ulcerans.

Full Text Available Cameroon is endemic for Buruli ulcer (BU and organised institutional BU control began in 2002. The objective was to describe the evolution, achievements and challenges of the national BU control programme (NBUCP and to make suggestions for scaling up the programme.We analysed collated data on BU from 2001 to 2014 and reviewed activity reports NBUCP in Cameroon. Case-detection rates and key BU control indicators were calculated and plotted on a time scale to determine trends in performance. A linear regression analysis of BU detection rate from 2005-2014 was done. The regression coefficient was tested statistically for the significance in variation of BU detection rate.In 14 years of BU control, 3700 cases were notified. The BU detection rate dropped significantly from 3.89 to 1.45 per 100 000 inhabitants. The number of BU endemic health districts rose from two to 64. Five BU diagnostic and treatment centres are functional and two more are planned for 2015. The health system has been strengthened and BU research and education has gained more interest in Cameroon.Although institutional BU control Cameroon only began 30 years after the first cases were reported in 1969, a number of milestones have been attained. These would serve as stepping stones for charting the way forward and improving upon control activities in the country if the major challenge of resource allocation is dealt with.

Full Text Available BACKGROUND: Buruli ulcer (BU is an emerging infectious disease caused by Mycobacterium ulcerans that can result in extensive necrotizing cutaneous lesions due to the cytotoxic exotoxin mycolactone. There is no specific vaccine against BU but reports show some degree of cross-reactive protection conferred by M. bovis BCG immunization. Alternatively, an M. ulcerans-specific immunization could be a better preventive strategy. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we used the mouse model to characterize the histological and cytokine profiles triggered by vaccination with either BCG or mycolactone-negative M. ulcerans, followed by footpad infection with virulent M. ulcerans. We observed that BCG vaccination significantly delayed the onset of M. ulcerans growth and footpad swelling through the induction of an earlier and sustained IFN-γ T cell response in the draining lymph node (DLN. BCG vaccination also resulted in cell-mediated immunity (CMI in M. ulcerans-infected footpads, given the predominance of a chronic mononuclear infiltrate positive for iNOS, as well as increased and sustained levels of IFN-γ and TNF. No significant IL-4, IL-17 or IL-10 responses were detected in the footpad or the DLN, in either infected or vaccinated mice. Despite this protective Th1 response, BCG vaccination did not avoid the later progression of M. ulcerans infection, regardless of challenge dose. Immunization with mycolactone-deficient M. ulcerans also significantly delayed the progression of footpad infection, swelling and ulceration, but ultimately M. ulcerans pathogenic mechanisms prevailed. CONCLUSIONS/SIGNIFICANCE: The delay in the emergence of pathology observed in vaccinated mice emphasizes the relevance of protective Th1 recall responses against M. ulcerans. In future studies it will be important to determine how the transient CMI induced by vaccination is compromised.

Full Text Available Culture of Mycobacterium ulcerans from Buruli ulcer patients has very low sensitivity. Thus confirmation of M. ulcerans infection is primarily based on PCR directed against IS2404. In this study we compare the genotypes obtained by variable number of tandem repeat analysis of DNA from IS2404-PCR positive cultures with that obtained from IS2404 positive, culture-negative tissue. A significantly greater genetic heterogeneity was found among culture-negative samples compared with that found in cultured strains but a single genotype is over-represented in both sample sets. This study provides evidence that both the focal location of bacteria in a lesion as well as differences in the ability to culture a particular genotype may underlie the low sensitivity of culture. Though preliminary, data from this work also suggests that mycobacteria previously associated with fish disease (M. pseudoshottsii may be pathogenic for humans.

Full Text Available BACKGROUND: Buruli Ulcer (BU is a tropical infectious skin disease that is currently treated with 8 weeks of intramuscular streptomycin and oral rifampicin. As prolonged streptomycin administration can cause both oto- and nephrotoxicity, we evaluated its long term toxicity by following-up former BU patients that had received either 4 or 8 weeks of streptomycin in addition to other drugs between 2006 and 2008, in the context of a randomized controlled trial. METHODS: Former patients were retrieved in 2012, and oto- and nephrotoxicity were determined by audiometry and serum creatinine levels. Data were compared with baseline and week 8 measurements during the drug trial. RESULTS: Of the total of 151 former patients, 127 (84% were retrieved. Ototoxicity was present in 29% of adults and 25% of children. Adults in the 8 week streptomycin group had significantly higher hearing thresholds in all frequencies at long term follow-up, and these differences were most prominent in the high frequencies. In children, no differences between the two treatment arms were found. Nephrotoxicity that had been detected in 14% of adults and in 13% of children during treatment, was present in only 2.4% of patients at long term follow-up. CONCLUSIONS: Prolonged streptomycin administration in the adult study subjects caused significant persistent hearing loss, especially in the high frequency range. Nephrotoxicity was also present in both adults and children but appeared to be transient. Streptomycin should be given with caution especially in patients aged 16 or older, and in individuals with concurrent risks for renal dysfunction or hearing loss.
Full Text Available Buruli ulcer (BU is an extensively damaging skin infection caused by Mycobacterium ulcerans, whose transmission mode is still unknown. The focal distribution of BU and the absence of interpersonal transmission suggest a major role of environmental factors, which remain unidentified. This study provides the first description of the spatio-temporal variations of BU in an endemic African region, in Akonolinga, Cameroon. We quantify landscape-associated risk of BU, and reveal local patterns of endemicity.From January 2002 to May 2012, 787 new BU cases were recorded in 154 villages of the district of Akonolinga. Incidence per village ranged from 0 (n = 59 villages to 10.4 cases/1000 person.years (py; median incidence was 0.4 cases/1,000 py. Villages neighbouring the Nyong River flood plain near Akonolinga town were identified as the highest risk zone using the SPODT algorithm. We found a decreasing risk with increasing distance to the Nyong and identified 4 time phases with changes in spatial distribution. We classified the villages into 8 groups according to landscape characteristics using principal component analysis and hierarchical clustering. We estimated the incidence ratio (IR associated with each landscape using a generalised linear model. BU risk was highest in landscapes with abundant wetlands, especially cultivated ones (IR = 15.7, 95% confidence interval [95%CI] = 15.7[4.2-59.2], and lowest in reference landscape where primary and secondary forest cover was abundant. In intermediate-risk landscapes, risk decreased with agriculture pressure (from IR[95%CI] = 7.9[2.2-28.8] to 2.0[0.6-6.6]. We identified landscapes where endemicity was stable and landscapes where incidence increased with time.Our study on the largest series of BU cases recorded in a single endemic region illustrates the local evolution of BU and identifies the Nyong River as the major driver of BU incidence. Local differences along the river are explained by wetland

Background Reducing social distance between hospital staff and patients and establishing clear lines of communication is a major challenge when providing in-patient care for people afflicted by Buruli ulcer (BU) and chronic ulcers. Research on hospitals as therapeutic communities is virtually non-existent in Africa and is currently being called for by medical anthropologists working in the field of health service and policy planning. This paper describes a pioneering attempt to establish a therapeutic community for patients suffering from BU and other chronic ulcers requiring long term hospital care in Benin. Methods A six-month pilot project was undertaken with the objectives of establishing a therapeutic community and evaluating its impact on practitioner and patient relations. The project was designed and implemented by a team of social scientists working in concert with the current and previous director of a hospital serving patients suffering from advanced stage BU and other chronic ulcers. Qualitative research initially investigated patients’ understanding of their illness and its treatment, identified questions patients had about their hospitalization, and ascertained their level of social support. Newly designed question–answer health education sessions were developed. Following these hospital wide education sessions, open forums were held each week to provide an opportunity for patients and hospital staff to express concerns and render sources of discontent transparent. Patient group representatives then met with hospital staff to problem solve issues in a non-confrontational manner. Psychosocial support for individual patients was provided in a second intervention which took the form of drop-in counseling sessions with social scientists trained to serve as therapy facilitators and culture brokers. Results Interviews with patients revealed that most patients had very little information about the identity of their illness and the duration of their
Full Text Available Buruli ulcer (BU caused by Mycobacterium ulcerans is a devastating skin disease, occurring mainly in remote West African communities with poor access to health care. Early case detection and subsequent antibiotic treatment are essential to counteract the progression of the characteristic chronic ulcerative lesions. Since the accuracy of clinical BU diagnosis is limited, laboratory reconfirmation is crucial. However, currently available diagnostic techniques with sufficient sensitivity and specificity require infrastructure and resources only accessible at a few reference centres in the African endemic countries. Hence, the development of a simple, rapid, sensitive and specific point-of-care diagnostic tool is one of the major research priorities for BU. In this study, we have identified a previously unknown M. ulcerans protein, MUL_3720, as a promising target for antigen capture-based detection assays. We show that MUL_3720 is highly expressed by M. ulcerans and has no orthologs in other prevalent pathogenic mycobacteria. We generated a panel of anti-MUL_3720 antibodies and used them to confirm a cell wall location for MUL_3720. These antibodies could also specifically detect M. ulcerans in infected human tissue samples as well as in lysates of infected mouse footpads. A bacterial 2-hybrid screen suggested a potential role for MUL_3720 in cell wall biosynthesis pathways. Finally, we demonstrate that a combination of MUL_3720 specific antibody reagents in a sandwich-ELISA format has sufficient sensitivity to make them suitable for the development of antigen capture-based diagnostic tests for BU.
Full Text Available This study was conducted with the aim to understand some of the cultural belief systems in the management of wounds and patients practices that could contaminate wounds at the Obom sub-district of the Ga South Municipality of Ghana.This was an ethnographic study using in-depth interviews, Focus Group Discussions and participant observation techniques for data collection. Observations were done on Buruli ulcer patients to document how they integrate local and modern wound management practices in the day-to-day handling of their wounds. Content analysis was done after the data were subjected to thematic coding and representative narratives selected for presentation.It was usually believed that wounds were caused by charms or spirits and, therefore, required the attention of a native healer. In instances where some patients' wounds were dressed in the hospital by clinicians whose condition/age/sex contradict the belief of the patient, the affected often redress the wounds later at home. Some of the materials often used for such wound dressing include urine and concoctions made of charcoal and gunpowder with the belief of driving out evil spirits from the wounds.Clinicians must therefore be aware of these cultural beliefs and take them into consideration when managing Buruli ulcer wounds to prevent redressing at home after clinical treatment. This may go a long way to reduce secondary infections that have been observed in Buruli ulcer wounds.
Full Text Available Buruli Ulcer (BU is a neglected infectious disease caused by Mycobacterium ulcerans that is responsible for severe necrotizing cutaneous lesions that may be associated with bone involvement. Clinical presentations of BU lesions are classically classified as papules, nodules, plaques and edematous infiltration, ulcer or osteomyelitis. Within these different clinical forms, lesions can be further classified as severe forms based on focality (multiple lesions, lesions' size (>15 cm diameter or WHO Category (WHO Category 3 lesions. There are studies reporting an association between delay in seeking medical care and the development of ulcerative forms of BU or osteomyelitis, but the effect of time-delay on the emergence of lesions classified as severe has not been addressed. To address both issues, and in a cohort of laboratory-confirmed BU cases, 476 patients from a medical center in Allada, Benin, were studied. In this laboratory-confirmed cohort, we validated previous observations, demonstrating that time-delay is statistically related to the clinical form of BU. Indeed, for non-ulcerated forms (nodule, edema, and plaque the median time-delay was 32.5 days (IQR 30.0-67.5, while for ulcerated forms it was 60 days (IQR 20.0-120.0 (p = 0.009, and for bone lesions, 365 days (IQR 228.0-548.0. On the other hand, we show here that time-delay is not associated with the more severe phenotypes of BU, such as multi-focal lesions (median 90 days; IQR 56-217.5; p = 0.09, larger lesions (diameter >15 cm (median 60 days; IQR 30-120; p = 0.92 or category 3 WHO classification (median 60 days; IQR 30-150; p = 0.20, when compared with unifocal (median 60 days; IQR 30-90, small lesions (diameter ≤15 cm (median 60 days; IQR 30-90, or WHO category 1+2 lesions (median 60 days; IQR 30-90, respectively. Our results demonstrate that after an initial period of progression towards ulceration or bone involvement, BU lesions become stable regarding size and focal

Buruli ulcer (BU) is a refractory skin ulcer caused by Mycobacterium ulcerans or M. ulcerans ssp. shinshuense, a subspecies thought to have originated in Japan or elsewhere in Asia. Although BU occurs most frequently in tropical and subtropical areas such as Africa and Australia, the occurrence in Japan has gradually increased in recent years. The World Health Organization recommends multidrug therapy consisting of a combination of oral rifampicin (RFP) and i.m. streptomycin (SM) for the treatment of BU. However, surgical interventions are often required when chemotherapy alone is ineffective. As a first step in developing a standardized regimen for BU treatment in Japan, we analyzed detailed records of treatments and prognoses in 40 of the 44 BU cases that have been diagnosed in Japan. We found that a combination of RFP (450 mg/day), levofloxacin (LVFX; 500 mg/day) and clarithromycin (CAM; at a dose of 800 mg/day instead of 400 mg/day) was superior to other chemotherapies performed in Japan. This simple treatment with oral medication increases the probability of patient adherence, and may often eliminate the need for surgery.
Beninese Medicinal Plants as a Source of Antimycobacterial Agents: Bioguided Fractionation and In Vitro Activity of Alkaloids Isolated from Holarrhena floribunda Used in Traditional Treatment of Buruli Ulcer
Full Text Available Buruli ulcer (BU imposes a serious economic burden on affected households and on health systems that are involved in diagnosing the disease and treating patients. Research is needed to find cost-effective therapies for this costly disease. Plants have always been an important source of new pharmacologically active molecules. Consequently we decided to undertake the study of plants used in traditional treatment of BU in Benin and investigate their antimycobacterial activity as well as their chemical composition. Extracts from forty-four (44 plant species were selected on account of reported traditional uses for the treatment of BU in Benin and were assayed for antimycobacterial activities. Crude hydroethanolic extract from aerial parts of Holarrhena floribunda (G. Don T. Durand and Schinz was found to have significant antimycobacterial activity against M. ulcerans (MIC = 125 µg/mL. We describe here the identification of four steroidal alkaloids from Mycobacterium ulcerans growth-inhibiting fractions of the alkaloidal extract of the aerial parts of Holarrhena floribunda. Holadysamine was purified in sufficient amount to allow the determination of its MCI (=50 µg/mL. These results give some support to the use of this plant in traditional medicine.

Background Access to laboratory diagnosis can be a challenge for individuals suspected of Buruli Ulcer (BU). Our objective was to develop a clinical score to assist clinicians working in resource-limited settings for BU diagnosis. Methododology/Principal Findings Between 2011 and 2013, individuals presenting at Akonolinga District Hospital, Cameroon, were enrolled consecutively. Clinical data were collected prospectively. Based on a latent class model using laboratory test results (ZN, PCR, culture), patients were categorized into high, or low BU likelihood. Variables associated with a high BU likelihood in a multivariate logistic model were included in the Buruli score. Score cut-offs were chosen based on calculated predictive values. Of 325 patients with an ulcerative lesion, 51 (15.7%) had a high BU likelihood. The variables identified for the Buruli score were: characteristic smell (+3 points), yellow color (+2), female gender (+2), undermining (+1), green color (+1), lesion hyposensitivity (+1), pain at rest (-1), size >5cm (-1), locoregional adenopathy (-2), age above 20 up to 40 years (-3), or above 40 (-5). This score had AUC of 0.86 (95%CI 0.82–0.89), indicating good discrimination between infected and non-infected individuals. The cut-off to reasonably exclude BU was set at scores <0 (NPV 96.5%; 95%CI 93.0–98.6). The treatment threshold was set at a cut-off ≥4 (PPV 69.0%; 95%CI 49.2–84.7). Patients with intermediate BU probability needed to be tested by PCR. Conclusions/Significance We developed a decisional algorithm based on a clinical score assessing BU probability. The Buruli score still requires further validation before it can be recommended for wide use. PMID:27045293

Background Beyond Mycobacterium ulcerans—specific therapy, sound general wound management is required for successful management of Buruli ulcer (BU) patients which places them among the large and diverse group of patients in poor countries with a broken skin barrier. Methods Clinically BU suspicious patients were enrolled between October 2013 and August 2015 at a primary health care (PHC) center and a municipal hospital, secondary health care (SHC) center in Ghana. All patients were IS2404 PCR tested and divided into IS2404 PCR positive and negative groups. The course of wound healing was prospectively investigated including predictors of wound closure and assessment of infrastructure, supply and health staff performance. Results 53 IS2404 PCR positive patients—31 at the PHC center and 22 at the SHC center were enrolled—and additionally, 80 clinically BU suspicious, IS2404 PCR negative patients at the PHC center. The majority of the skin ulcers at the PHC center closed, without the need for surgical intervention (86.7%) compared to 40% at the SHC center, where the majority required split-skin grafting (75%) or excision (12.5%). Only 9% of wounds at the PHC center, but 50% at the SHC center were complicated by bacterial infection. The majority of patients, 54.8% at the PHC center and 68.4% at the SHC center, experienced wound pain, mostly severe and associated with wound dressing. Failure of ulcers to heal was reliably predicted by wound area reduction between week 2 and 4 after initiation of treatment in 75% at the PHC center, and 90% at the SHC center. Obvious reasons for arrested wound healing or deterioration of wound were missed additional severe pathology; at the PHC center (chronic osteomyelitis, chronic lymphedema, squamous cell carcinoma) and at the SHC center (malignant ulceration, chronic lymphedema) in addition to hygiene and wound care deficiencies. When clinically suspicious, but IS2404 PCR negative patients were recaptured in the community, 76

Over the past few decades, since the introduction of histamine H(2)-receptor antagonists, proton-pump inhibitors, cyclo-oxygenase-2-selective anti-inflammatory drugs (coxibs), and eradication of Helicobacter pylori infection, the incidence of peptic ulcer disease and ulcer complications has decreased. There has, however, been an increase in ulcer bleeding, especially in elderly patients. At present, there are several management issues that need to be solved: how to manage H. pylori infection when eradication failure rates are high; how best to prevent ulcers developing and recurring in nonsteroidal anti-inflammatory drug (NSAID) and aspirin users; and how to treat non-NSAID, non-H. pylori-associated peptic ulcers. Looking for H. pylori infection, the overt or surreptitious use of NSAIDs and/or aspirin, and the possibility of an acid hypersecretory state are important diagnostic considerations that determine the therapeutic approach. Combined treatment with antisecretory therapy and antibiotics for 1-2 weeks is the first-line choice for H. pylori eradication therapy. For patients at risk of developing an ulcer or ulcer complications, it is important to choose carefully which anti-inflammatory drugs, nonselective NSAIDs or coxibs to use, based on a risk assessment of the patient, especially if the high-risk patient also requires aspirin. Testing for and eradicating H. pylori infection in patients is recommended before starting NSAID therapy, and for those currently taking NSAIDs, when there is a history of ulcers or ulcer complications. Understanding the pathophysiology and best treatment strategies for non-NSAID, non-H. pylori-associated peptic ulcers presents a challenge.

Full Text Available BACKGROUND: Buruli ulcer (BU is a necrotizing bacterial infection of skin, subcutaneous tissue and bone caused by Mycobacterium ulcerans. Although the functional impairment caused by BU results in severe suffering and in socio-economic problems, the disease remains largely neglected in Africa. The province of Bas-Congo in Democratic Republic of Congo contains one of the most important BU foci of the country, i.e. the Songololo Territory in the District of Cataractes. This study aims to assess the impact of a BU control project launched in 2004 in the Songololo Territory. METHODS: We used a comparative non-randomized study design, comparing clinical profiles and outcomes of the group of patients admitted at the General Reference Hospital (GRH of the "Institut Médical Evangélique" (IME of Kimpese 3 years before the start of the project (2002-2004 with those admitted during the 3 years after the start of the project (2005-2007. RESULTS: The BU control project was associated with a strong increase in the number of admitted BU cases at the GRH of IME/Kimpese and a fundamental change in the profile of those patients; more female patients presented with BU, the proportion of relapse cases amongst all admissions reduced, the proportion of early lesions and simple ulcerative forms increased, more patients healed without complications and the case fatality rate decreased substantially. The median duration since the onset of first symptoms however remained high, as well as the proportion of patients with osteomyelitis or limitations of joint movement, suggesting that the diagnostic delay remains substantial. CONCLUSION: Implementing a specialized program for BU may be effective in improving clinical profiles and outcomes in BU. Despite these encouraging results, our study highlights the need of considering new strategies to better improve BU control in a low resources setting.

Efforts to control the spread of Buruli ulcer--an emerging ulcerative skin infection caused by Mycobacterium ulcerans--have been hampered by our poor understanding of reservoirs and transmission. To help address this issue, we compared whole genomes from 18 clinical M. ulcerans isolates from a 30 km2 region within the Asante Akim North District, Ashanti region, Ghana, with 15 other M. ulcerans isolates from elsewhere in Ghana and the surrounding countries of Ivory Coast, Togo, Benin and Nigeria. Contrary to our expectations of finding minor DNA sequence variations among isolates representing a single M. ulcerans circulating genotype, we found instead two distinct genotypes. One genotype was closely related to isolates from neighbouring regions of Amansie West and Densu, consistent with the predicted local endemic clone, but the second genotype (separated by 138 single nucleotide polymorphisms [SNPs] from other Ghanaian strains) most closely matched M. ulcerans from Nigeria, suggesting another introduction of M. ulcerans to Ghana, perhaps from that country. Both the exotic genotype and the local Ghanaian genotype displayed highly restricted intra-strain genetic variation, with less than 50 SNP differences across a 5.2 Mbp core genome within each genotype. Interestingly, there was no discernible spatial clustering of genotypes at the local village scale. Interviews revealed no obvious epidemiological links among BU patients who had been infected with identical M. ulcerans genotypes but lived in geographically separate villages. We conclude that M. ulcerans is spread widely across the region, with multiple genotypes present in any one area. These data give us new perspectives on the behaviour of possible reservoirs and subsequent transmission mechanisms of M. ulcerans. These observations also show for the first time that M. ulcerans can be mobilized, introduced to a new area and then spread within a population. Potential reservoirs of M. ulcerans thus might include

During the summer of 1933, lesions of a disease were noted among some fingerling brook, rainbow, blackspotted, and lake trout at the Cortland (New York) trout hatchery. Although these lesions bore a marked superficial resemblance to those of furunculosis, they were sufficiently atypical to warrant further investigation. A more detailed examination of the lesions proved them to be of a distinct disease, which for lack of a better name is herein called "ulcer disease," for the lesions closely resemble those described by Calkins (1899) under this name. Because of the marked resemblance to furunculosis, ulcer disease has not been generally recognized by trout culturists, and any ulcer appearing on fish has been ascribed by them to furunculosis without further question.

Full Text Available Buruli ulcer (BU is a neglected tropical disease affecting the skin, tissues and in some cases the bones, caused by the environmental pathogen Mycobacterium ulcerans (M. ulcerans. Its mode of transmission is still elusive. Delayed treatment may cause irreversible disabilities with consequent social and economic impacts on the victim. Socio-cultural beliefs, practices and attitudes in endemic communities have been shown to influence timely treatment causing disease management, prevention and control a great challenge. An assessment of these factors in endemic localities is important in designing successful intervention strategies. Considering this, we assessed the knowledge, attitude and practices regarding BU in three endemic localities in the South West region, Cameroon to highlight existing misconceptions that need to be addressed to enhance prompt treatment and facilitate effective prevention and control.A cross-sectional study was executed in three BU endemic health districts. Using qualitative and quantitative approaches we surveyed 320 randomly selected household heads, interviewed BU patients and conducted three focus group discussions (FGDs to obtain information on awareness, beliefs, treatment, and attitudes towards victims. The influence of socio-demographic factors on these variables was investigated.Respondents (84.4% had a good knowledge of BU though only 65% considered it a health problem while 49.4% believed it is contagious. Socio-demographic factors significantly (P<0.05 influenced awareness of BU, knowledge and practice on treatment and attitudes towards victims. Although the majority of respondents stated the hospital as the place for appropriate treatment, FGDs and some BU victims preferred witchdoctors/herbalists and prayers, and considered the hospital as the last option. We documented beliefs about the disease which could delay treatment.Though we are reporting a high level of knowledge of BU, there exist fallacies about

Full Text Available Buruli ulcer (BU, a neglected tropical disease of the skin, caused by Mycobacterium ulcerans, occurs most frequently in children in West Africa. Risk factors for BU include proximity to slow flowing water, poor wound care and not wearing protective clothing. Man-made alterations of the environment have been suggested to lead to increased BU incidence. M. ulcerans DNA has been detected in the environment, water bugs and recently also in mosquitoes. Despite these findings, the mode of transmission of BU remains poorly understood and both transmission by insects or direct inoculation from contaminated environment have been suggested. Here, we investigated the BU epidemiology in the Mapé basin of Cameroon where the damming of the Mapé River since 1988 is believed to have increased the incidence of BU. Through a house-by-house survey in spring 2010, which also examined the local population for leprosy and yaws, and continued surveillance thereafter, we identified, till June 2012, altogether 88 RT-PCR positive cases of BU. We found that the age adjusted cumulative incidence of BU was highest in young teenagers and in individuals above the age of 50 and that very young children (<5 were underrepresented among cases. BU lesions clustered around the ankles and at the back of the elbows. This pattern neither matches any of the published mosquito biting site patterns, nor the published distribution of small skin injuries in children, where lesions on the knees are much more frequent. The option of multiple modes of transmission should thus be considered. Analyzing the geographic distribution of cases in the Mapé Dam area revealed a closer association with the Mbam River than with the artificial lake.

Non-tuberculous mycobacteria (NTM), particularly mycolactone producing mycobacteria (MPM), are bacteria found in aquatic environments causing skin diseases in humans like Buruli ulcer (BU). Although the causative agent for BU, Mycobacterium ulcerans has been identified and associated with slow-moving water bodies, the real transmission route is still unknown. This study aimed to characterize MPMs from environmental aquatic samples collected in a BU non-endemic community, Adiopodoumé, in Côte d’Ivoire. Sixty samples were collected in four types of matrices (plant biofilms, water filtrate residues, plant detritus and soils) from three water bodies frequently used by the population. Using conventional polymerase chain reaction (PCR), MPMs were screened for the 16S ribosomal RNA (rRNA) mycobacterial gene, the IS2404 insertion sequence, and MPM enoyl reductase (ER) gene. Variable Number Tandem Repeat (VNTR) typing with loci 6, 19, mycobacterial interspersed repetitive unit 1 (MIRU1) and sequence type 1(ST1) was performed to discriminate between different MPMs. Our findings showed 66.7%, 57.5% and 43.5% of positivity respectively for 16S rRNA, IS2404 and ER. MPM discrimination using VNTR typing did not show any positivity and therefore did not allow precise MPM distinction. Nevertheless, the observed contamination of some water bodies in a BU non-endemic community by MPMs suggests the possibility of pathogen dissemination and transmission to humans. These aquatic environments could also serve as reservoirs that should be considered during control and prevention strategies. PMID:28208653

The discovery that Helicobacter pylori infection is the major cause of peptic ulcer disease revolutionised our views on the etiology and treatment of the disease. This discovery has tempted many experts to conclude that psychological factors and, specifically, stress are unimportant. However, Helicobacter pylori infection alone does not explain fully the incidence and prevalence of peptic ulcer disease. It has been demonstrated that stress can cause peptic ulcer disease even in the absence of Helicobacter pylori infection, supporting a multicausal model of peptic ulcer etiology. Psychological stress among other risk factors can function as a cofactor with Helicobacter pylori infection.

Full Text Available Buruli ulcer (BU is a cutaneous infectious disease caused by Mycobacterium ulcerans. The exact mode of transmission remains elusive; yet, some studies identified environmental, socio-sanitary, and behavioral risk factors. The purpose of this study was to assess the association of such factors to contracting BU in Tiassalé, south Côte d'Ivoire.A case-control study was conducted in 2012. Cases were BU patients diagnosed according to clinical definition put forth by the World Health Organization, readily confirmed by IS2404 polymerase chain reaction (PCR analysis prior to our study and recruited at one of the health centers of the district. Two controls were matched for each control, by age group (to the nearest 5 years, sex, and living community. Participants were interviewed after providing oral witnessed consent, assessing behavioral, environmental, and socio-sanitary factors.A total of 51 incident and prevalent cases and 102 controls were enrolled.

Intestinal Behcet's disease in a 38-year-old woman was diagnosed because of the history of recurrent oral aphthous ulcers, erythema nodosum-like eruptions,genital ulcer, and endoscopic findings of esophageal and ileocolonic punched-out ulcers with colonic longitudinal ulcers. Esophageal lesions and colonic longitudinalulcers are rarely seen in intestinal Behcet's disease. The ulcers of esophagus and ileocolon healed with 3 wk of treatment with prednisolone and mesalazine without any adverse effect. Mesalazine may decrease the total dose of prednisolone required to treat the disease.

Full Text Available BACKGROUND: Delay in seeking treatment at the hospital is a major challenge in current Buruli ulcer control; it is associated with severe sequelae and functional limitations. Choosing alternative treatment and psychological, social and practical factors appear to influence delay. Objectives were to determine potential predictors for pre-hospital delay with Leventhal's commonsense model of illness representations, and to explore whether the type of available dominant treatment modality influenced individuals' perceptions about BU, and therefore, influenced pre-hospital delay. METHODOLOGY: 130 healthy individuals aged >18 years, living in BU-endemic areas in Benin without any history of BU were included in this cross-sectional study. Sixty four participants from areas where surgery was the dominant treatment and sixty six participants from areas where antibiotic treatment was the dominant treatment modality were recruited. Using a semi-structured interview we measured illness perceptions (IPQ-R, knowledge about BU, background variables and estimated pre-hospital delay. PRINCIPAL FINDINGS: The individual characteristics 'effectiveness of treatment' and 'timeline acute-chronic' showed the strongest association with pre-hospital delay. No differences were found between regions where surgery was the dominant treatment and regions where antibiotics were the dominant treatment modality. CONCLUSIONS: Individual characteristics, not anticipated treatment modality appeared predictors of pre-hospital delay.

Authors in this article present etiology, clinical manifestations, diagnostic procedures and treatment of peptic ulcer disease in children and adults. Increased gastric acid output, Helicobacter pylori, NSAIDs and stress are the basic risk factors in peptic ulcer disease. H. pylori infection is a widely known risk factor in peptic ulcer disease and influences diagnostic and treatment procedures. Primary ulcer disease concerns mainly duodenum and is accompanied by H. pylori infection. Gastroscopy and Helicobacter tests are the only reliable procedures to diagnose peptic ulcer disease. Nowadays the most important aim in peptic ulcer treatment is the H. pylori eradication. Therapy with two antibiotics and a protein pomp inhibitor eradicates the bacteria, treats the ulceration and lowers the number of ulcer recurrence. In non-infected H. pylori ulcers or in a long-term treatment protein pomp inhibitors and H2-inhibitors are effective as well in gastroprotective therapy.
Refractory PUD is a diagnostic and therapeutic challenge. Optimal management of severe or refractory PUD requires a multidisciplinary team approach, using primary care providers, gastroenterologists, and general surgeons. Medical management has become the cornerstone of therapy. Identification and eradication of H pylori infection combined with acid reduction regimens can heal ulceration and also prevent recurrence. Severe, intractable or recurrent PUD and associated complications mandates a careful and methodical evaluation and management strategy to determine the potential etiologies and necessary treatment (medical or surgical) required.

Peptic ulcer is one of the most prevalent diseases in gastrointestinal field. Recently, evolution was made for pathophysiology of peptic ulcer from "no acid, no ulcer" to Helicobacter pylori and non-steroidal anti-inflammatory drugs. The prevalence of peptic ulcer disease is estimated about 10% in Korea, and has declined due to Helicobacter pylori eradication therapy. Peptic ulcer has the cycle of exacerbation and improvement in the clinical course, and has not occasionally any clinical symptom. Helicobacter pylori eradication has made the marked reduction of relapse of peptic ulcer disease. Although nationwide endoscopic screening has enabled accurate diagnosis of peptic ulcer disease, general guideline for diagnosis of peptic ulcer has not made in Korea. Herein, we propose a guideline for the diagnosis of peptic ulcer according to domestic, international clinical studies, and experts opinions with level of evidence and grade of recommendation.

Misoprostol, a synthetic prostaglandin E1 (PGE1) methyl ester analog has potent antisecretory and cytoprotective effects on the gastric and duodenal mucosa which should make it an effective drug in the treatment of gastric and duodenal ulcer. In two multicenter, randomised, double-blind, controlled studies involving over 900 patients with endoscopically proven benign gastric ulcer and in six similar studies involving over 2000 patients with active duodenal ulcers, differing doses of misoprostol have been compared with either placebo therapy or with conventional doses of cimetidine. In these studies misoprostol 800 mcg daily given as two or four divided doses has been shown to produce rates of complete ulcer healing and pain relief which were significantly superior to placebo therapy and comparable to those achieved with cimetidine. Drug related adverse effects were infrequent. A dose related diarrhea occurred in a small proportion of patients which seldom necessitated suspension of therapy. Because of the known uterotropic effect of prostaglandins the drug should not be used in pregnant women or women of child bearing age unless they are using adequate contraceptive measures. No clinically significant adverse, hematological or biochemical effects have been reported. Two studies suggested that misoprostol reduced the adverse effect of smoking on the healing of duodenal ulcer. In addition, misoprostol has been shown to protect the gastro-duodenal mucosa from the damaging effects of alcohol and non-steroidal anti-inflammatory drugs. This action may prove of value in the treatment of ulcer patients who are inveterate smokers, alcohol users or who are compelled to consume non-steroidal anti-inflammatory drugs for pain relief from rheumatic and allied diseases.

For more than a century, peptic ulcer disease has been a major cause of morbidity and mortality. Peptic ulcer disease is a heterogeneous group of disorders involving the gastrointestinal tract and results from an imbalance between the aggressive forces of gastric acid and pepsin and the defensive mechanisms of the gastric mucosa.

Treatment of peptic ulcer disease has undergone a radical change due to the discovery of its main cause, the Helicobacter pylori infection. The management of the chronic infection is now the primary aim. Treatment of peptic ulcer essentially consists of eradicating H. pylori. A current problem is the resistance developed by H. pylori to the antibiotics used in eradication regimen. Ulcers that are induced by nonsteroidal antirheumatic (NSAR) agents and acetylsalicylic acid are gaining in importance. Optimized inhibition of acid secretion with proton pump inhibitors has made it possible to both prevent and cure ulcers in the stomach and duodenum caused by NSAR agents.

Full Text Available The etiology of peptic ulcer is multifactorial; except for omeprazole, all drugs used for the treatment of peptic ulcer result in healing with no statistical difference at four weeks. The healing rare increases with time for active medication and placebo, and is lower among smokers than nonsmokers for all drugs but misoprostol. Mucosal protectives (or ‘cytoprotectives’ as a group seem to have a lower relapse rate than the H2 receptor antagonists at one year. Combination therapy has not yet proved to be better than single drug therapy; however, the number of studies is still small, and more clinical trials are necessary. Resistant ulcers have demonstrated that acid is one of several etiological factors and that more research is needed to elucidate the reason(s for refractoriness. The choice of therapeutic agent is generally made according to patient compliance, medication cost, side effects, effectiveness, relapse rate and physician experience with the drug. Long term maintenance therapy is effective in the prevention of ulcer relapse and is especially recommended for selected patient groups, including patients with recurrent or bleeding ulcer, patients with concomitant nonsteroidal anti-inflammatory drug use, and elderly women. Omeprazole is the treatment of choice for moderate to severe esophagitis and should be reserved for large and resistant ulcers.
Prevalence of H. pylori (HP) is declining, whereas reflux disease and the proportion of non-steroidal antiinflammatory drugs (NSAR) to HP-induced ulcers increase. Eradication heals HP-ulcer disease, interrupts cancerous progression and can improve dyspeptic symptoms. NSAR-ulcers heal under proton pump inhibitor (PPI) therapy but tend to recur after reexposition. Anticoagulants and antiplatlet agents increase the risk additionally. PPI reduces NSAR-ulcer recurrence. Reflux patients with severe inflammation and complications often need long-term therapy. Barrett’s esophagus patients are at risk of esophageal adenocarcinoma.

with perfusion, etc. Currently the leading cause of PUD is H. pylori infection. Standard triple eradication therapy is losing interest in favor of quadruple therapy (PPI, bismuth, tetracycline, metronidazole). H. pylori-induced PPI is rapidly disappearing in the Western world, in contrast to drug-induced ulcer disease and what is called idiopathic PUD. Partial prophylaxis of ASA/NSAID-induced ulceration is possible with PPI maintenance therapy, but novel ways to strengthen the mucosal defense are urgently awaited.

Peptic ulcer disease remains a common problem and it most frequently due to the presence of an Helicobacter pylori infection or use of non-steroidal anti-inflammatory drugs (NSAIDs). Dyspepsia is neither sensitive or specific for diagnosing peptic ulcer disease. The approach to patients with dyspepsia is to arrive at a definitive diagnosis without unnecessary exposure to invasive or costly diagnostic procedures. Non-invasive testing is preferred with endoscopy being reserved for those with alarm markers or above a specified age (e.g., 55 years in Western countries). Patients negative for H. pylori infection should receive an empiric trial of acid suppression for 4 to 8 weeks and if beneficial it can be continued.
Over the last decade, a new disease entity, prolonged ulcerative laryngitis (PUL), with unique clinical presentation and prolonged disease course, has been recognized. Until now, very few studies dealing with this disease have been reported in the literature. From 1999 to 2008, we analyzed clinical data from a series of 39 PUL patients who were treated with an observational approach without implementing specific treatments. This disease affects adults, predominantly females. The age of patients in our series ranged from 26 to 76 years with a median of 49.5 years. This disease is characterized by ulcers and signs of acute inflammation on the membranous portion of the vocal folds with a prolonged clinical course. The recovery times of patients ranged from 4 to 20 weeks with an average of 9.4 weeks. The data in this study may reflect a natural history of this disease. PUL seems to be a self-limited disease, but the etiology of this disease is unknown. Specific infections or systemic inflammatory processes involving the larynx must be ruled out before diagnosis, and conservative treatments are suggested.

We report a 74-year-old man with Wernicke's encephalopathy (WE) whose only prior illness was peptic ulcer disease. Upper gastrointestinal endoscopy demonstrated gastric ulcer scars accompanied by marked deformity, without pathologic evidence of malignancy. WE due to peptic ulcer disease in previous reports was substantially associated with thiamine deficiency due to recurrent vomiting or surgical procedures. In our case, however, there was no history of vomiting or gastrointestinal surgery. Besides, we thoroughly ruled out other known clinical settings related to WE. There is the possibility that peptic ulcer disease itself provoked thiamine deficiency due to malabsorption.

Data of 363 patients operated on for perforated gastric or duodenal ulcers were analyzed. Immediate and follow-up results were obtained after simple suture plication, Jadd's ulcer excision combined with stem vagotomy and after distal gastric resection. Predictors of the unfavourable outcome were determined. These are: Mannheim peritonitis index >20, surgical risk of IV-V grade, signs of multiple organ failure and symptomatic character of the ulcer. The comparison of long-term results revealed that patients after suture plication experienced the ulcer recurrence in 78,4% and necessity of further operation occurred in 21,5%. Every third patient after stem vagotomy experienced postvagotomic disorders and ulcer recurrence. Primary gastric resection demonstrated the best long-term results concerning ulcer disease. The algorithm of treatment modalities of the perforative ulcer desease was worked. The algorithm is based on stage-by stage determination of indications and contraindications to gastric resection.

Summary Background Large leg ulcers (LLU) may complicate autoimmune diseases. They pose a therapeutic challenge and are often resistant to treatment. To report three cases of autoimmune diseases complicated with LLU. Case Report Case 1. A 55-year old woman presented with long-standing painful LLU due to mixed connective tissue disease (MCTD). Biopsy from the ulcer edge showed small vessel vasculitis. IV methylprednisolone (MethP) 1 G/day, prednisolone (PR) 1mg/kg, monthly IV cyclophosphamide (CYC), cyclosporine (CyA) 100mg/day, IVIG 125G, ciprofloxacin+IV Iloprost+enoxaparin+aspirin (AAVAA), hyperbaric oxygen therapy (HO), maggot debridement and autologous skin transplantation were performed and the LLU healed. Case 2. A 45-year old women with MCTD developed multiple LLU’s with non-specific inflammation by biopsy. MethP, PR, hydroxychloroquine (HCQ), azathioprine (AZA), CYC, IVIG, AAVAA failed. Treatment for underlying the LLU tibial osteomyelitis and addition of CyA was followed by the LLU healing. Case 3. A 20-year-old man with history of polyarteritis nodosa (PAN) developed painful LLU’s due to small vessel vasculitis (biopsy). MethP, PR 1 mg/kg, CYC, CyA 100 mg/d, AAVAA failed. MRSA sepsis and relapse of systemic PAN developed. IV vancomycin, followed by ciprofloxacin, monthly IVIG (150 g/for 5 days) and infliximab (5 mg/kg) were instituted and the LLU’s healed. Conclusions LLU are extremely resistant to therapy. Combined use of multiple medications and services are needed for healing of LLU due to autoimmune diseases. PMID:21169912

Over the past decade, while gastroenterologists' interest in mind-body interactions in organic disorders dwindled, stronger evidence has linked psychosocial factors with the incidence and recurrence of peptic ulcer and with the course of inflammatory bowel disease. Psychological-behavioral approaches to treatment continue to be disappointing. Psychosocial factors may affect ulcer by increasing duodenal acid load, altering local circulation or motility, intensifying Helicobacter pylori infection, stimulating corticosteroid secretion, and affecting health risk behaviors; possible mechanisms for inflammatory bowel disease include immune deregulation, gut permeability changes, and poor medication adherence. Both belong to the growing category of diseases thought to have an infectious component: for peptic ulcer the bacterium Helicobacter pylori, for inflammatory bowel disease an exaggerated immune response to gut bacteria. Peptic ulcer and inflammatory bowel disease, which present unique interactions among psychological, immunologic, endocrine, infectious, and behavioral factors, are splendid paradigms of the biopsychosocial model.

Rheumatic diseases often have gastrointestinal(GI) manifestations, and may present as GI bleeding and perforation due to peptic ulcer associated with high mortality. Major causes of peptic ulcer related to rheumatic diseases are drugs such as nonsteroidal anti-inflammatory drug(NSAID) and corticosteroid, and vasculitis. The analgesic effects of NSAID often mask abdominal pain until they cause GI bleeding and perforation. Therefore, it is important to make early diagnosis of peptic ulcer with upper gastrointestinal endoscope. Fundamental treatment of NSAID induced peptic ulcer is to quit it, however it is difficult because of activity of rheumatic diseases. Also, most NSAID induced peptic ulcers heal by administration of proton pump inhibitor or misoprostol. Corticosteroid pulse therapy or administration of immunosuppressant agents is effective for vasculitis induced peptic ulcer, however it is difficult to make diagnosis of it. Development of NSAID with less side effects such as cyclooxygenase-2 selective inhibitors and establishment of diagnosis and treatment of peptic ulcer related to rheumatic diseases are expected.

Over the past century, since the introduction of non steroidal anti-inflammatory drugs (NSAID), antacid, histamine H2-receptor antagonists (H2RA), proton pump inhibitors (PPI), and discovery of Helicobacter pylori infection, the paradigm of peptic ulcer disease has changed with marked decrease in morbidity and mortality. However, peptic ulcer disease still occupies a position as a major health problem with increase of aged population and NSAIDs usage. In daily general practice, the management of peptic ulcer disease is directed according to the presence of bleeding or not. For non-bleeding peptic ulcer disease, proper acid suppression and the correction of underlying causes such as Helicobacter pylori infection and NSAID use is the main stay of treatment. Though a complete understanding of pathophysiology and a perfect treatment strategy are still a challenge, this guideline aims to provide practical recommendations based on evidences or consensus of experts through in-depth literature review and expert meeting.
Hepatobiliary diseases are certainly not very frequent extraintestinal complications of chronic intestinal inflammatory diseases, however, they are an important prognostic factor. 2% of patients with ulcerative colitis develop liver cirrhosis but 10% of those die as a direct result of liver failure. Other associated severe hepatobiliary diseases include primary sclerosing cholangitis, carcinoma of the bile duct and amyloidosis. The present review attempts to divide the associated hepatobiliary diseases into three groups. 1. those that are the result of therapy. 2. those that are the result of the pathophysiological mechanisms of the underlying disease and 3. those of unknown etiological origin. This division might serve not only for a better understanding of the various mechanisms but should have some impact on therapeutic regimens.

BACKGROUND: Crohn's disease and ulcerative colitis are the two major forms of inflammatory bowel disease; treatment strategies have historically been determined by this binary categorisation. Genetic studies have identified 163 susceptibility loci for inflammatory bowel disease, mostly shared...... between Crohn's disease and ulcerative colitis. We undertook the largest genotype association study, to date, in widely used clinical subphenotypes of inflammatory bowel disease with the goal of further understanding the biological relations between diseases. METHODS: This study included patients from 49...... centres in 16 countries in Europe, North America, and Australasia. We applied the Montreal classification system of inflammatory bowel disease subphenotypes to 34,819 patients (19,713 with Crohn's disease, 14,683 with ulcerative colitis) genotyped on the Immunochip array.

Because the normal faecal flora includes bacteria which can produce mucus-digesting glycosidases, it follows that increased digestion of colonic mucus by these bacterial enzymes could be important in the pathogenesis of ulcerative colitis. Faecal activities of potential mucus-degrading glycosidases have therefore been assayed in samples from patients with inflammatory bowel disease and normal controls. The enzymes alpha-D-galactosidase, beta-D-galactosidase, beta-NAc-D-glucosaminidase alpha-L-fucosidase and neuraminidase were assayed. Considerable glycosidase activity was present in most faecal samples. Similar activities of all the enzymes assayed were found in faeces from patients with ulcerative colitis, Crohn's disease and normal controls and there was no significant correlation with disease activity. These results imply that relapse of ulcerative colitis is not initiated by increased degradation of colonic mucus by faecal glycosidases but do not exclude a role for bacterial mucus degradation in the pathogenesis of ulcerative colitis.

Non-steroidal anti-inflammatory drug (NSAID) use increases the risk of gastrointestinal complications such as ulcers or bleeding. The presence of factors like advanced age, history of peptic ulcer, Helicobacter pylori infection and the use of anticoagulants or antiplatelet agents increase this risk further. COX-2 inhibitors and antisecretory drugs, particularly proton pump inhibitors, help to minimize the risk of gastrointestinal complications in high-risk patients. This review presents a practical approach to the prevention and treatment of NSAID-associated peptic ulcer disease and examines the new advances in the rational use of NSAIDs.

For much of the twentieth century, surgery was frequently the solution for peptic ulcer disease. Our understanding of the pathophysiology of ulcers paralleled the development of potent pharmaceutical therapy. As the surgical world developed parietal cell vagotomy which would minimize the complications of surgery,patients failing medical therapy became rare. Emergent surgery for complicated peptic ulcers has not declined however. The development of proton pump inhibitors and the full understanding of the impact of H pylori has led to a trend towards minimalism in surgical therapy for complicated peptic ulcer disease. In addition to the changes in patient care, these developments have had an impact on the training of surgeons. This article outlines these trends and developments.

Recent data report that the incidence of peptic ulcer is decreasing in the general population; conversely, the rates of gastric and duodenal ulcer hospitalization and mortality remain very high in older patients. Two major factors that might explain this epidemiological feature in the elderly population are the high prevalence of Helicobacter pylori infection and the increasing prescriptions of gastroduodenal damaging drugs, including NSAIDs and/or aspirin (acetylsalicylic acid). The main goals for treating peptic ulcer disease in old age are to reduce recurrence of the disease and to prevent complications, especially bleeding and perforation. The available treatments for peptic ulcer are essentially based on gastric acid suppression with antisecretory drugs and the eradication of H. pylori infection. The aim of this article is to report the available data on clinical efficacy and tolerability of peptic ulcer treatments in elderly patients and provide recommendations for their optimal use in this special population. Proton pump inhibitor (PPI)-based triple therapies for 7 days are highly effective for the cure of H. pylori-positive peptic ulcers as well as for reducing ulcer recurrence. Antisecretory drugs are also the treatment of choice for NSAID- or aspirin-related peptic ulcers and are useful as preventive therapy in chronic users of NSAIDs and low-dose aspirin as antiplatelet therapy. Antisecretory PPI therapy has a favourable tolerability profile in geriatric patients; however, monitoring is suggested in older patients with frequent pulmonary infections, gastrointestinal malabsorption, unexplained chronic diarrhoea, osteoporosis or those taking concomitant cytochrome P450 2C19-metabolized medications. The overall approach to the geriatric patient should include a comprehensive geriatric assessment that ensures multidimensional evaluation of the patient in order to better define the clinical risk of adverse outcomes in the older patient with peptic ulcer and

The pathogenesis, incidence, complication rates, response to acid suppression and Helicobacter pylori (H. pylori) eradication therapy in peptic ulcer associated with chronic disease such as liver cirrhosis, chronic renal failure, diabetes mellitus, and critically ill conditions are different from those with general population, so that the management strategies also should be differentiated. The eradication of H. pylori are not so effective for preventing recurrence of peptic ulcer in liver cirrhosis patients as shown in general population, and conservative managements such as preventing deterioration of hepatic function and decrease in portal pressure are mandatory to reduce the risk of ulcer recurrence. The standard triple therapy for H. pylori eradication are as effective in chronic renal failure patients as in normal population, but the frequency of side effects of amoxicillin is higher in the patients not receiving dialysis therapy. Delay in eradication therapy until beginning of dialysis therapy or modification of eradication regimen should be considered in such cases. High prevalence of asymptomatic peptic ulcers and increased mortality in complicated peptic ulcer disease warrant regular endoscopic surveillance in diabetic patients, especially with angiopathy. The prolongation of duration of eradication therapy also should be considered in diabetic patients with angiopathic complication because of lower eradication rate with standard triple regimens as compared to normal population. Prophylactic acid suppressive therapy is highly recommended in critically ill patients with multiple risk factors. Herein, we propose evidence-based treatment guidelines for the management of peptic ulcer disease in special conditions based on literature review and experts opinion.

The isoprenoid pathway produces three key metabolites--endogenous digoxin-like factor (EDLF) (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), ubiquinone (free radical scavenger), and dolichol (regulator of glycoconjugate metabolism). The pathway was assessed in peptic ulcer and acid peptic disease and its relation to hemispheric dominance studied. The activity of HMG CoA reductase, serum levels of EDLF, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in acid peptic disease, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. All the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listening test. The pathway was upregulated with increased EDLF synthesis in peptic ulcer disease (PUD). There was increase in tryptophan catabolites and reduction in tyrosine catabolites in these patients. The ubiquinone levels were low and free radical production increased. Dolichol and glycoconjugate levels were increased and lysosomal stability reduced in patients with acid peptic disease (APD). There was increase in cholesterol:phospholipid ratio with decreased glyco conjugate levels in membranes of patients with PUD. Acid peptic disease represents an elevated EDLF state which can modulate gastric acid secretion and the structure of the gastric mucous barrier. It can also lead to persistence of Helicobacter pylori infection. The biochemical pattern obtained in peptic ulcer disease is similar to those obtained in left-handed/right hemispheric chemically dominant individuals. But all the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listen ing test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Peptic ulcer disease occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function.

Evidence is reviewed that Helicobacter pylori infection may cause a deficiency of the hormone secretin that allows peptic ulcer disease to develop by impairing the body's defenses to gastric acid. Secretin is released into the circulation from the S-cells of the duodenal crypts in response to gastric acid entering the duodenum. Once in the circulation, secretin has five well-documented effects that protect the upper intestine from gastric acid: it stimulates secretion of bicarbonate rich exocrine pancreatic juice; it stimulates secretion of alkaline bile; it stimulates secretion of alkaline mucus from the duodenal submucosal glands of Brunner; it inhibits the humoral phase of gastric secretion; and it inhibits gastric motility, thereby delaying gastric emptying. Impaired secretin release and reduced duodenal S-cells have been documented in peptic ulcer patients compared with control patients. Clinical evidence that patients with H. pylori infection and peptic ulceration have increased gastric secretion and motility and decreased duodenal bicarbonate response to gastric acid, all of which normalize after eradication of the infection, could be explained by reversible impairment of the secretin mechanism. Gastric metaplasia in the duodenum with H. pylori infection is known to reduce the S-cell population. The fact that not all patients with H. pylori infection develop peptic ulceration suggests that degree of secretin deficiency determined by extent of the infection must reach a critical level for peptic ulceration to occur. Peptic ulceration may be a hormonal deficiency disease, a result of secretin deficiency caused by H. pylori infection. It may be the first example of a specific hormonal deficiency disease caused by a specific bacterial infection.

Full Text Available Cryptogenic Multifocal Ulcerous Stenosing Enteritis (CMUSE is a rare idiopathic disease of the small bowel. Its origin and pathophysiology has not been well described. Clinicopathologic features include unexplained ileal strictures with supercial ulceration. We present a case of a 31-year-old HIV positive lady who was admitted with complaints of recurrent abdominal pain and constipation. Laboratory investigations revealed iron deciency anemia. Ultrasonography of the abdomen showed dilated bowel loops and a subsequent barium follow through showed ve strictures in the ileum. Segmental small bowel resection with end-to-end anastomosis was performed. Grossly ileum showed ve ileal strictures. The diagnosis of CMUSE was made on histopathology after ruling out other causes of strictures. The present case highlights the importance of considering CMUSE in patients with chronic or recurrent episodes of intestinal obstruction with multiple small intestinal ulcers and strictures after other common causes have been ruled out.

The presence of gastric acid plays a critical role in the mechanisms of NSAIDs/aspirin-associated gastric and duodenal mucosal injury and ulceration. The role of gastric acid and its relationship to NSAIDs/aspirin in mucosal damage, ulcer and ulcer complications continues to be an important concern because of the increasing worldwide use of NSAIDs and aspirin. Acid suppression continues to be an important prevention strategy for NSAID-associated gastric and duodenal ulcer and ulcer complications. While a coxib or an NSAID and PPI in combination are considered to have comparable safety profiles, the evidence from direct comparisons in high-risk patients is limited, and the cardiovascular safety of coxibs and NSAIDs remains a concern especially in patients with a high risk of cardiovascular disease. An evaluation of individual gastrointestinal and cardiovascular risks and benefits, selection of the most appropriate NSAID and dose for each particular patient should always be emphasized. Twice daily PPI is more appropriate to protect a patient who is taking NSAIDs twice daily. PPI co-therapy is still recommended in patients receiving dual antiplatelet treatment, although conflicting results have been reported about adverse drug interactions between PPIs and clopidogrel.

Full Text Available Three cases of coexisting ulcerative colitis and Crohn’s disease are presented. In the first case, the patient had a long-standing history of ulcerative proctitis before developing Crohn’s colitis. In the two remaining cases, the patients presented initially with Crohn’s disease of the ileum and, subsequent to resection, developed ulcerative colitis. Well-documented cases of patients diagnosed with both ulcerative colitis and Crohn’s disease are rare. The literature on such cases is reviewed, and the controversy over whether ulcerative colitis and Crohn’s disease are two distinct diseases is explored.
Conclusion About 70% of our patients with ulcerative colitis in clinical remission had an active disease. Clinical remission in ulcerative colitis can be best expressed as true and false remission depending on histological grading in a revised ulcerative colitis disease activity index. Some inflammatory markers can be useful for the detection of true remission.

Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases.

The story of gastric acid secretion began with early ideas on gastric secretion (Spallanzani and de Réaumur, 17th century) and with first descriptions of food digestion (Dupuytren and Bichat, Beaumont, early 18th century), followed by proof that gastric juice contained acid (Prout, early 18th century). The research continued with first descriptions of gastric glands as the source of gastric acid and its changes upon digestive stimulus (Purkinje and Golgi, mid and late 19th century). The theory of 'nervism' - the neuro-reflex stimulation of gastric secretion by vagal nerve (Pavlov, early 20th century) was contrasted by a histamine-mediated concept of gastric secretion (Popielski and Code, mid 20th century). Thus, gastric acid and pepsin (Schwann, early 19th century) were found to be essential for food digestion and studies also pointed to histamine, being the most potent final common chemostimulator of oxyntic cells. The discoveries in etiopathogenesis of mucosal injury were marked by the famous dictum: 'No acid, no ulcer' ('Ohne saueren Magensaft kein peptisches Geschwür', Schwarz, 1910) that later induced the term of 'mucosal defense' and the notion that the breaking of 'gastric mucosal barrier' represents the initial step in the process of mucosal injury (Davenport, Code and Scholer, mid 20th century). The prostaglandins were shown to influence all major components of gastric mucosal barrier, described with the term 'cytoprotection' (Vane, Robert and Jacobson, 1970s). Beginning in the latter half of 19th century, the studies on gastric bacteriology that followed enabled the discovery of association between Campylobacter (Helicobacter) pylori and peptic ulcers (Warren and Marshall, 1980s) that led to worldwide major interventions in treating peptic ulcer disease. The surgical approach to peptic ulcer had been outlined by resection procedures (Billroth, Pean, Moynihan, late 19 century) and vagotomy, with or without drainage procedures (Jaboulay, Latarjet

AIM: To investigate and compare frequencies of serum positive cagA in patients from two separate regions of Turkey who were grouped according to the presence of peptic ulcer disease or non-ulcer dyspepsia.METHODS: One hundred and eighty Helicobacter pyloripositive patients with peptic ulcer disease or non-ulcer dyspepsia were included in the study. One hundred and fourteen patients had non-ulcer dyspepsia and 66 had peptic ulcer disease (32 with gastric ulcers and/or erosions and 34with duodenal ulcers). Each patient was tested for serum antibody to H. pylori cagA protein by enzyme immunoassay.RESULTS: The total frequency of serum positive cagA in the study group was 97.2 %. The rates in the patients with peptic ulcers and in those with non-ulcer dyspepsia were 100% and 95.6%, respectively. These results were similar to those reported in Asian studies, but higher than those that have been noted in other studies from Turkey and Western countries.CONCLUSION: The high rates of serum positive cagA in these patients with peptic ulcer disease and non-ulcer dyspepsia were similar to results reported in Asia. The fact that there was high seroum prevalence regardless of ulcer status suggests that factors other than cagA might be responsible for ulceration or other types of severe pathology in H. pylori-positive individuals.

The recognition of Helicobacter pylori infection as a cause of peptic ulcer disease, medical regimens to eradicate the organism, and the widespread use of proton pump inhibition to suppress gastric acid secretion have revolutionized the management of peptic ulcer disease. As a result, successful medical management of peptic ulcer disease has largely supplanted the need for gastric surgery by general surgeons. Surgery is reserved for complications of the disease, refractory disease, or rare causes of ulcer disease such as gastrinoma and Zollinger-Ellison syndrome. In this report, we describe a case of intractable peptic ulcer disease that progressed to gastric outlet obstruction despite maximal medical therapy. We review the diagnostic studies utilized to evaluate the potential etiologies of peptic ulcer disease and the difficulty in diagnosing gastrinoma and Zollinger-Ellison in the setting of potent medical acid suppression therapy.

Crohn's disease and ulcerative colitis evolve with a relapsing and remitting course.Determination of infiammatory state is crucial for the assessment of disease activity and for tailoring therapy.However,no simple diagnostic test for monitoring intestinal inflammation is available.Noninvasive markers give only indirect assessments of disease activity.Histopathological or endoscopical examinations accurately assess inflammatoryactivity,but they are invasive,time consuming and expensive and therefore are unsuitable for routine use.Imaging procedures are not applicable for ulcerative colitis.The usefulness of ultrasound and Doppler imaging in assessing disease activity is still a matter of discussion for Crohn's disease,and an increased interest in computed tomography enterograph (CTE) has been seen,mainly because it can delineate the extent and severity of bowel wall inflammation,besides detecting extraluminal findings.Until now,the available data concerning the accuracy of magnetic resonance enterography in detecting disease activity is less than CTE.Due to this,clinical activity indices are still commonly used for both diseases.

Therapeutic gastric irradiation has been used to reduce peptic juice secretion in patients with peptic ulcer disease. Between 1937 and 1968 a total of 2049 patients received such therapy at the University of Chicago. Three of these patients are known to have developed sarcomas in the field of radiation. Two gastric leiomyosarcomas of the stomach were diagnosed 26 and 14 years after treatment and a malignant fibrous histiocytoma of the anterior chest wall was removed six years after gastric irradiation. Of 743 peptic ulcer patients treated without irradiation and constituted as a control group for the study of therapeutic gastric radiation, none is known to have developed sarcoma. As the incidence of sarcoma in these patient groups is known only from the tumor registry of the University of Chicago, other cases of sarcoma may exist in the groups. While an increased incidence of sarcoma has not been proven to occur in patients who received therapeutic gastric irradiation for peptic ulcer disease, the possibility of such a risk should be borne in mind by physicians caring for such patients.

OBJECTIVE. To analyse outcomes of patients who underwent emergency gastrectomy for complicated peptic ulcer disease. DESIGN. Prognostic study on a historical cohort. SETTING. A regional hospital in Hong Kong. PATIENTS. Patients who underwent emergency gastrectomy from 2000 to 2009 in our hospital. MAIN OUTCOME MEASURES. Primary outcome measures were in-hospital mortality and the predictors of such deaths. Secondary outcome measures were 7-day mortality, 30-day mortality, and morbidities. RESULTS. In all, 112 patients had emergency gastrectomies performed for complicated peptic ulcer disease during the study period. In-hospital mortality was 30%. In the univariate analysis, old age, duodenal ulcer, failed primary surgery, gastrojejunostomy anastomosis for reconstruction, hand-sewn technique for duodenal stump closure, use of a sump drain, low haemoglobin level, preoperative blood transfusion, prolonged prothrombin time, and high creatinine or bilirubin levels were associated with an increased risk of in-hospital mortality. In the multivariate analysis, failed primary surgery, old age, and high creatinine level turned out to be independent risk factors. CONCLUSIONS. Emergency gastrectomy should be considered seriously as the primary treatment option in appropriately selected elderly patients, instead of salvage procedures to repair a perforation or control bleeding by plication.

Full Text Available Peptic ulcer is a worldwide health problem because of its high morbidity, mortality and enormous financial implication. An estimated 15,000 deaths per year occur as a consequence of complicated PUD. A large number of drugs for peptic ulcer disease are available in mainstream medicine but they are associated with numerous side effects like arrhythmias, impotence, gynaecomastia and haematopoietic changes and the recurrence is also very common. In recent times, focus on plant research has increased all over the world and a large body of evidence has been collected to show immense potential of medicinal plants used in various traditional systems. Here, an attempt is made to summarise experimentally proved herbs used in PUD during last decade.

Although the global prevalence of peptic ulcer disease (PUD) is decreasing, PUD is still one of the most common upper gastrointestinal diseases in the world due to Helicobacter pylori infection and increased use of non-steroidal anti-inflammatory drugs. In Korea, the prevalence of H. pylori infection is also declining, but it is still the major cause of PUD. The outcomes of H. pylori infection are caused by imbalances between bacterial virulence factors, host factors, and environmental influences. In this review, we describe the prevalence trends of H. pylori infection in Korea, the mechanism of H. pylori infection-related PUD, and treatment strategies.

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

To determine the etiology of genital ulcers and to assess the prevalence of human immunodeficiency virus (HIV) infection in ulcer patients in 10 US cities, ulcer and serum specimens were collected from approximately 50 ulcer patients at a sexually transmitted disease clinic in each city. Ulcer specimens were tested using a multiplex polymerase chain reaction assay to detect Haemophilus ducreyi, Treponema pallidum, and herpes simplex virus (HSV); sera were tested for antibody to HIV. H. ducreyi was detected in ulcer specimens from patients in Memphis (20% of specimens) and Chicago (12%). T. pallidum was detected in ulcer specimens from every city except Los Angeles (median, 9% of specimens; range, 0%-46%). HSV was detected in >/=50% of specimens from all cities except Memphis (42%). HIV seroprevalence in ulcer patients was 6% (range by city, 0%-18%). These data suggest that chancroid is prevalent in some US cities and that persons with genital ulcers should be a focus of HIV prevention activities.

A 44-year-old man with upper abdominal pain, diarrhea and 25 kg weight loss since 3 months ago was admitted. He had a history of dyspepsia and peptic ulcer disease 4 months before admission. Gastroduodenal endoscopy and upper gastrointestinal series with barium study were done. Biopsies and CT-scan ruled out malignancies. Endoscopy and radiology studies revealed a duodenocolic fistula. He underwent right hemicolectomy, fistula en bloc excision, and distal gastrectomy surgery with gastrojejunostomy and ileocolic anastomosis. Radiologic modalities are necessary before surgery. Surgery is the only curative treatment in benign cases and reconstruction method is dependent on patient's situation.

Although genital ulcers are a common manifestation of Behçet's disease, bleeding from these lesions is unusual. In this report, a patient with excessive bleeding from genital ulcers is presented. A 22-year-old man with recurrent oral and genital ulcers, erythema nodosum, folliculitis, positive pathergic reaction, uveitis, superior vena cava syndrome, and generalized lymphadenopathy fulfilled the diagnostic criteria of Behçet's disease. Three years after presenting he was admitted to our clinic with excessive bleeding from large ulcers on the scrotum and upper thighs and with a leg ulcer. Bleeding was controlled with compresses. Examination of a biopsy specimen obtained from the leg ulcer showed findings consistent with Kaposi-like acroangiodermatitis. Results of various radiologic investigations showed thrombosis of the inferior vena cava, peritesticular varicosities, and venous insufficiency of the lower extremities. We suggest that the bleeding was secondary to the extension of genital ulcers to the varicose veins.

The sexual transmitted pathogens associated with genital ulcers are Treponema pallidum, Haemophilus ducreyi, Calymmatobacterium granulomatis, Chlamydia trachomatis and Herpes simplex virus type 1 or 2. Although geographic differences still exist, herpetic infections prevalence is growing worldwide as the most frequent ulcerative sexual transmitted disease. The failure of the many different used guidelines in achieving a sustained reduction in the number of new cases, in particular the WHO syndromic management, leads into an over treatment of bacterial agents and missing of viral agents. This situation is also associated with poor efficacy and wasting of economical resources. Ulcerative and non-ulcerative sexual transmitted diseases are important in the world HIV pandemy because they promote HIV transmission and are also associated with the disease evolution. Portugal had until recently the highest incidence of HIV infection in Europe and that points out to importance of treating and control of both ulcerative and non-ulcerative sexual transmitted diseases in order.

The author discusses the views of V. Kh. Vasilenko on etiology and pathogenesis of ulcer disease expounded in his last publications and compares them with modern concepts of the origin of this condition. The nature of ulcer disease as a systemic gastrointestinal pathology is considered with special emphasis on its difference from secondary (symptomatic) ulceration, pathogenetic significance of H. pylori infection, hereditary and environmental (non-infectious) factors. Much attention is given to the conditions facilitating the development of ulcer diseases at different combinations of internal and environmental factors including such poorly known ones as immune and sanogenetic mechanisms.

Peptic ulcer disease including both gastric and duodenal ulcer form a substantial part of patients seeking surgical opinion world-wide. The concept of acid in peptic ulcer disease, which was the basis of treatment of peptic ulcer was revolutionized by the discovery of H2-receptor antagonists, that led to the principle of acid suppression therapy for duodenal ulcer which followed decades of preference for surgical interventions in the form of gastric resections, vagotomy etc., After the discov...

Non-Helicobacter pylori, non-NSAID peptic ulcer disease (PUD), termed idiopathic PUD, is increasing in Korea. Diagnosis is based on exclusion of common causes such as H. pylori infection, infection with other pathogens, surreptitious ulcerogenic drugs, malignancy, and uncommon systemic diseases with upper gastrointestinal manifestations. The clinical course of idiopathic PUD is delayed ulcer healing, higher recurrence, higher re-bleeding after initial ulcer healing, and higher mortality than the other types of PUD. Genetic predisposition, older age, chronic mesenteric ischemia, cigarette smoking, concomitant systemic diseases, and psychological stress are considered risk factors for idiopathic PUD. Diagnosis of idiopathic PUD should systematically explore all possible causes. Management of this disease is to treat underlying disease followed by regular endoscopic surveillance to confirm ulcer healing. Continuous proton pump inhibitor therapy is an option for patients who respond poorly to the standard ulcer regimen.

Background. Helicobacter pylori (HP) infection and nonsteroidal anti-inflammatory drugs (NSAID) use are considered the main risk to develop peptic ulcer disease (PUD). However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV) reactivation increases the risk to develop premalignant and malignant gastric lesions. Objective. To study a possible association between EBV and PUD. Methods. Antibodies against an EBV reactivation antigen, HP, and the HP virulence factor CagA were measured in sera from 207 Mexican subjects, controls (healthy individuals, n = 129), and PUD patients (n = 78, 58 duodenal and 20 gastric ulcers). Statistical associations were estimated. Results. Duodenal PUD was significantly associated with high anti-EBV IgG titers (p = 0.022, OR = 2.5), while anti-EBV IgA was positively associated with gastric PUD (p = 0.002, OR = 10.1). Conclusions. Our study suggests that EBV reactivation in gastric and duodenal epithelium increases the risk to develop PUD.

A retrospective analysis was done of 106 patients who received radiation therapy for brain metastasis. Dexamethasone therapy was instituted in 97 patients. Peptic ulcer disease developed in 5 of 89 patients (5.6 percent) who received a dosage of at least 12 mg a day, but did not occur in patients who received a lower dose or in those who did not receive steroids. The interval between institution of dexamethasone therapy and the development of peptic ulcer disease ranged from three to nine weeks. Two patients had perforated ulcers, one of whom required surgical resection. Peptic ulcer disease contributed to the general deterioration and death of three of the five patients. Overall, in 14 of the 89 patients (15.7 percent) a complication of steroid therapy developed in the form of peptic ulcer disease, steroid myopathy or diabetes mellitus (or a combination of these).

This review summarizes the data of Russian and foreign authors as well as the results of original studies on etiology pathogenesis, and differential treatment of ulcer disease (UD). The author's original concepts of UD pathogenesis and relations between man and Helicobacter pylori are discussed. The pathogenetic role of disturbances in the system of gastroduodental self-regulatory function and psychosomatic mechanisms as well as immune deficiency and impaired antioxidatve protection is considered. Peculiarities and results of UD eradication therapy intended to eliminate H. pylori infection are described. The importance of the choice of the UD treatment strategy on an individual basis is emphasized as opposed to the use of universal standards and therapeutic modalities influencing only local pathogenic factors, such as acidopeptic ones and H. pylori infection.

The authors describe a patient with ulcerative colitis and extracolonic manifestations in whom diffuse interstitial pulmonary disease developed that was responsive to glucocorticoid therapy one year after total proctocolectomy. The patient presented in December 1983 with a subacute course marked by cough and progressive exertional dyspnea, abnormal chest examination results, and a chest roentgenogram that revealed diffuse interstitital and alveolar infiltrates. A transbronchial biopsy specimen revealed a polymorphic interstitial infiltrate, mild interstitial fibrosis without apparent intraluminal fibrosis, and no vasculitis, granulomas, or significant eosinophilic infiltration. Within one week of the initiation of daily high-dose steroid therapy, the patient's symptoms dramatically improved; chest roentgenogram and forced vital capacity (60%) improved at a slower rate. All three measures deteriorated when alternate-day prednisone therapy was started but once again improved until the patient was totally asymptomatic, chest roentgenograms were normal, and forced vital capacity was 80% of the predicted value 2 1/2 years later.

Full Text Available Objective: to compare clinical manifestations, course, mental status in duodenal ulcer (DU patients with a history of perforated ulcer and its uncomplicated course.Subjects and methods. One hundred and thirteen patents with DU were examined. Group 1 included 61 patients with uncomplicated DUand Group 2 comprised 52 patients with a history of perforated ulcer. A comparison group consisted of 20 patients who had undergone laparotomy. Physical and mental status examinations, esophagogastroduodenoscopy (EGDS, and 24-hour pH-metry were performed.Results. Classical pain syndrome was observed in 75 % of the patients with uncomplicated DU. Prior to perforation, the pain and dyspeptic syndromes were distinguished only by a significantly lower degree in Group 2; following perforation, the pain syndrome was recorded more frequently, it was more extensive, meal-unrelated, and similar to that in the patients who had undergone laparotomy and had diminished appetite (36.5 %. EGDS showed that the complicated course was accompanied by the significantly higher incidence of erosive esophagitis (21.2 %, gastritis (51.9 %, duodenitis (25.0 %, multiple ulcers (28.8 %, and larger ulcers. 24-hour pH-metry indicated that the level of hyperacidity in Group 2 was higher and the circadian intragastric pH variations were less marked than those in uncomplicated DU. The patients with a history of perforated ulcer showed a high rate of anxiety and depressive changes. Conclusion. In complicated DU, marked monotonic hyperacidity causes common erosive-ulcerative lesions in the gastroduodenal area in relatively mild pain syndrome, late referrals, and long-term ulcer healing. After perforation followed by wound closure, the pain and dyspeptic syndromes become more pronounced, which is associated with anxiety and depressive changes in the mental status, as well as with early referrals and less healing time.

There is increasing evidence that genital ulceration, including syphilis, chancroid, and herpes simplex type 2, increases susceptibility to HIV infection. It may be that the HIV penetrates more easily through ulcerated membranes or that the lymphocytes associated with the inflammatory response present target cells for HIV infection. There is also evidence that HIV-infected women with genital ulcers are themselves more infective due to shedding of the virus in the genital tract. Nonulcerative sexually-transmitted diseases have also been associated as cofactors of HIV infection. Programs for the control of sexually transmitted diseases should be strengthened and should focus on eliminating chancroid, which is easily treated with antibiotics. Patients with genital ulcer disease should receive counseling, so that they will know that untreated genital ulcers increase the risk of HIV infection.

Based on the analysis of literature data and our own research, we have developed the original concept of etiology and pathogenesis of peptic ulcer disease. An analysis of the literature shows that none of the theories of pathogenesis of peptic ulcer disease does not cover the full diversity of the involved functions and their shifts, which lead to the development of ulcers in the stomach and the duodenum. Our neurogenic-genetic theory of etiology and pathogenesis of gastric ulcer and duodenal ulcer very best explains the cause-and-effect relationships in the patient peptic ulcer, allowing options for predominance in one or the other case factors of neurosis or genetic factors. However, it is clear that the only other: combination of neurogenic factor with genetically modified reactivity of gastroduodenal system (the presence of the target organ) cause the chronicity of the sores. The theory of peptic ulcer disease related to psychosomatic pathologies allows us to develop effective schema therapy, including drugs with psychocorrective action. On the basis of our theory of the role of Helicobacter pylori infection is treated as a pathogenetic factor in the development of peptic ulcer disease.

Bowel-wall tissue filtrates from patients with inflammatory bowel disease produce cytopathic effects in tissue culture. The cytopathic effects inducers have been reported to have the characteristics of a small RNA virus. Clostridium difficile toxin also produces cytopathic effects and has been found in the stools of patients with Crohn's disease and ulcerative colitis. The present study concerns the further characterization of the cytopathic inducers in tissues of inflammatory bowel disease patients. It was found that they are nonsedimentable at 148,000 g for 2 h and resistant to inactivation by UV light. They are proteins that are distinct from C. difficile toxin and are unique cytotoxins which are associated with the early cytopathic effects observed in Riff-free chick embryo and rabbit ileum cell cultures. These results suggest that the early cytopathic effects previously described are not produced by a virus. They do not explain the delayed cytopathic effects seen in rabbit ileum or WI-38 cells.

An important role has been ascribed to plasma factor XIII (FXIII) in inflammation and wound healing. FXIII is necessary for fibrin stabilization and interacts with connective tissue and adhesive proteins and cells. In a prospective study, FXIII activity and parameters of coagulation, fibrinolysis and inflammation, were determined in patients with ulcerative colitis (UC; 13 active, 22 moderate) and Crohn's disease (CD; 36 active, 45 moderate). FXIII levels were lower in active than in moderate UC and CD, and were < 70% of normal values in 7/13 patients with active UC, and in 7/36 patients with active CD, although the median values did not fall below the normal range. FXIII was somewhat higher in active UC patients responding to therapy. The FXIII levels were widely scattered, and low values appear to be due to greatly enhanced turnover. A correlation between FXIII and the systemic levels of markers of activation of haemostasis and inflammation was lacking, but there was a correlation with the extent of bowel involvement. FXIII levels were lower in the patients with involvement beyond the sigmoid colon in CU (p = 0.0045), and both small and large bowel segments in CD (p = 0.0223) patients. This points to local consumption and/or loss of FXIII within the inflamed tissue, and provides an argument for FXIII substitution in the treatment of acute episodes of inflammatory bowel diseases.

The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.

There are fewer significant changes in the medical therapy of ulcerative colitis (UC) compared to Crohn's disease. The most important factors that determine therapy are disease extent and severity. 5-aminosalicylates (5-ASA) constitute the treatment of choice in mild-to-moderate UC. The efficacy of new compounds (e.g. mesalazine) is only mildly improved compared to sulphasalazine; however, their use has become more frequent due to a more favorable side effects profile. Topical medication is more effective in proctitis and distal colitis, and the combination of topical and orally-administered drugs is superior to oral therapy alone also in extensive disease. Thus, this latter regimen should be considered for cases where the escalation of treatment is required. Systemic steroids still represent the first line therapy in acute, severe UC, while in patients who do not respond to steroids, cyclosporine and infliximab should be considered as a second line therapy and as alternatives for colectomy. Maintenance treatment is indicated in all UC cases. 5-ASA compounds are suggested as first line maintenance therapy with the optimal dose still being under investigation. Topical compounds are effective also for maintenance in distal colitis or proctitis, if accepted by the patients. Immunosuppressives, especially azathioprine, should be considered in chronically active, steroid dependent or resistant patients. According to recent publications, azathioprine is almost equally effective in UC and CD. The question of chemoprevention is important during maintenance. There are increasing data supporting the notion that aminosalicylates may lower the risk for UC-associated colorectal cancer. The most important changes in the management of UC are the more frequent use of topical aminosalicylates and azathioprine, the availability of infliximab in severe UC, and increasing use of aminosalicylates for chemoprevention of colorectal carcinoma. Furthermore, adequate attention is needed to

Endoscopic hemostasis is the first-line treatment for upper gastrointestinal bleeding (UGIB). Although several factors are known to be risk factors for rebleeding, little is known about the use of antithrombotics. We tried to verify whether the use of antithrombotics affects rebleeding rate after a successful endoscopic hemostasis for peptic ulcer disease (PUD). UGIB patients who underwent successful endoscopic hemostasis were included. Rebleeding was diagnosed when the previously treated lesion bled again within 30 days of the initial episode. Of 522 UGIB patients with PUD, rebleeding occurred in 93 patients (17.8%). The rate of rebleeding was higher with aspirin medication (P=0.006) and after a long endoscopic hemostasis (P<0.001). Of all significant variables, procedure time longer than 13.5 min was related to the rate of rebleeding (OR, 2.899; 95% CI, 1.768-4.754; P<0.001) on the logistic regression analysis. The rate of rebleeding after endoscopic hemostasis for PUD is higher in the patients after a long endoscopic hemostasis. Endoscopic hemostasis longer than 13.5 min is related to rebleeding after a successful endoscopic hemostasis for PUD.

AIM:To evaluate the relationship between peptic ulcer disease (PUD) and acute pancreatitis.METHODS:A cohort of 78 patients with acute pancreatitis were included in this study.The presence of PUD and the Helicobacter pylori (H.pylori ) status were assessed by an endoscopic method.The severity of acute pancreatitis was assessed using Ranson's score, the Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score,computed tomography severity index and the clinical data during hospitalization,all of which were compared between the patients with and without PUD.The risk factors for PUD were also evaluated. RESULTS:Among 78 patients,41 patients (52.6%) with acute pancreatitis suffered from PUD,but only 13 (31.7%) patients with PUD were infected by H.pylori .On univariate analysis,male gender,an etiology of alcohol-induced pancreatitis,a history of smoking or alcohol consumption, elevated triglyceride and C-reactive protein levels, and high APACHE Ⅱ score were significantly associated with PUD.However,on multivariate logistic regression analysis,the APACHE Ⅱ score (odds ratio:7.69; 95% confidence interval:1.78-33.33; P < 0.01) was found to be the only independent risk factor for PUD.CONCLUSION:Patients with acute pancreatitis are liable to suffer from PUD.PUD is associated with severe acute pancreatitis according to the APACHE Ⅱ score, and treatment for PUD should be considered for patients with severe acute pancreatitis.

Peritonitis due to gastroduodenal ulcer perforation disease is a rare entity in pediatric surgery. In Senegal, no study has been dedicated to ulcer complications in children. The aim of this study was to describe the epidemiology, diagnosis, and treatment of perforated peptic ulcer in patients less than 15 years old. This retrospective study was conducted in the Surgical Emergencies and Paediatric Surgery Department at Aristide Le Dantec University Hospital Center in Dakar, Senegal, during a period of 11 years (January 1999 to December 2010). We found 4 children who presented perforated gastroduodenal ulcer: 3 females and 1 male. The average age of these patients was 9 years (range, 7-14 years). No family history was found. We noted 3 cases of perforated duodenal ulcer and one perforated gastric ulcer. The clinical diagnosis was suspected based on a peritoneal irritation syndrome. A plain x-ray of the abdomen was taken in all patients, which objectified a pneumoperitoneum image in 3 cases. The leukocytosis was constant. Treatment in all patients consisted on pre-, intra-, and postoperative intensive care, supra- and infraumbilical midline laparotomy, which allowed us to perform a debridement-suture of the gap followed by epiploplasty and extensive washing with lukewarm physiologic serum. Adjuvant therapy based on anti-ulcer and antibiotic therapy was initiated. Bacteriological examination of peritoneal fluid isolated a polymicrobial flora. Helicobacter pylori was not isolated. Histological examination of the biopsied perforation edges showed a benign ulcer in all cases. The follow-up endoscopy was performed 4 weeks after surgery and showed cicatrization of the ulcer in all patients. After a mean of 2 years, no recurrence was noted. The gastric or duodenal ulcer in children is rare. It is often discovered at the stage of perforation, a complication for which the essential treatment is surgery. Routine screening would certainly help to reduce the risk of this

The gastric pathogen Helicobacter pylori utilizes molecular hydrogen (H2) as a respiratory substrate during colonization in the gastric mucosa. However, the link between molecular H2 and the pathogenesis of peptic-ulcer disease (PUD) and non-ulcerous dyspepsia (NUD) by the enzymatic activity of H. pylori still remains mostly unknown. Here we provide evidence that breath H2 excretion profiles are distinctly altered by the enzymatic activity of H. pylori for individuals with NUD and PUD. We subsequently unravelled the potential molecular mechanisms responsible for the alteration of H2 in exhaled breath in association with peptic ulcers, encompassing both gastric and duodenal ulcers, along with NUD. We also established that carbon-isotopic fractionations in the acid-mediated bacterial environment regulated by bacterial urease activity cannot discriminate the actual disease state i.e. whether it is peptic ulcer or NUD. However, our findings illuminate the unusual molecular H2 in breath that can track the precise evolution of PUD and NUD, even after the eradication of H. pylori infection. This deepens our understanding of the pathophysiology of PUD and NUD, reveals non-invasively the actual disease state in real-time and thus offers a novel and robust new-generation strategy for treating peptic-ulcer disease together with non-ulcer related complications even when the existing (13)C-urea breath test ((13)C-UBT) fails to diagnose.

Behçet disease is a complex, multisystem disease characterized by recurrent oral and genital ulcerations. It rarely occurs in infants or children. Neonatal Behçet disease has been reported in infants whose ulcers resolve at or before 9 weeks of age. Few cases of neonatal Behçet disease persisting into childhood have previously been reported. We report the case of a 1-month-old infant who presented with severe recurrent genital ulcerations and at 6 months developed recurrent oral ulcerations. Her orogenital ulcerations continue to recur. Human leukocyte antigen testing revealed HLA-B51 and B44 positivity. This is a case of pediatric Behçet disease in the neonatal period. Behçet disease should be considered in the differential diagnosis of recurrent genital and oral ulcerations in infants and children.

This review article on the surveillance of patients with ulcerative colitis provides an overview of the criteria for evaluating screening and surveillance programs and applies the criteria to the available evidence to determine the effectiveness of the surveillance of patients with ulcerative colitis. We examine the clinical outcomes associated with surveillance, the additional clinical time required to confirm the diagnosis of dysplasia and cancer, compliance with surveillance and follow-up, and the effectiveness of the individual components of a surveillance program, including colonoscopy and pathologist's interpretation. The disability associated with colectomy is considered, as are the cost and acceptability of surveillance programs. Patients with long-standing ulcerative colitis are at risk for developing colorectal cancer. Recommended surveillance colonoscopy should be supported. New endoscopic and histopathologic techniques to improve the identification of high-risk patients may enhance the effectiveness and cost-effectiveness of surveillance practices.

Curcumin is known to possess anti‑inflammatory properties. Despite the fact that curcumin is known to be a strong inhibitor of H+, K+‑ATPase activity, the mechanism underlying the curcumin‑induced inhibition of the transcription of the H+, K+‑ATPase α subunit in gastric mucosal parietal cells remains unclear. The present study investigated the possible mechanism by which curcumin inhibits stomach H+, K+‑ATPase activity during the acute phase of gastric ulcer disease. A rat model of stress‑induced gastric ulcers was produced, in which the anti‑ulcer effects of curcumin were examined. Curcumin‑induced inhibition of the H+, K+‑ATPase promoter via histone acetylation, was verified using a chromatin immunoprecipitation assay. The results showed that curcumin improved stress‑induced gastric ulcer disease in rats, as demonstrated by increased pH values and reduced gastric mucosal hemorrhage and ulcer index. These effects were accompanied by a significant reduction in the level of histone H3 acetylation at the site of the H+, K+‑ATPase promoter and in the expression of the gastric H+,K+‑ATPase α subunit gene and protein. In conclusion, curcumin downregulated the acetylation of histone H3 at the site of the H+, K+‑ATPase promoter gene, thereby inhibiting the transcription and expression of the H+, K+‑ATPase gene. Curcumin was shown to have a preventive and therapeutic effect in gastric ulcer disease.

The purpose of this paper is to present a new method to detect ulcers, which is one of the symptoms of Crohn's disease, from CT images. Crohn's disease is an inflammatory disease of the digestive tract. Crohn's disease commonly affects the small intestine. An optical or a capsule endoscope is used for small intestine examinations. However, these endoscopes cannot pass through intestinal stenosis parts in some cases. A CT image based diagnosis allows a physician to observe whole intestine even if intestinal stenosis exists. However, because of the complicated shape of the small and large intestines, understanding of shapes of the intestines and lesion positions are difficult in the CT image based diagnosis. Computer-aided diagnosis system for Crohn's disease having automated lesion detection is required for efficient diagnosis. We propose an automated method to detect ulcers from CT images. Longitudinal ulcers make rough surface of the small and large intestinal wall. The rough surface consists of combination of convex and concave parts on the intestinal wall. We detect convex and concave parts on the intestinal wall by a blob and an inverse-blob structure enhancement filters. A lot of convex and concave parts concentrate on roughed parts. We introduce a roughness value to differentiate convex and concave parts concentrated on the roughed parts from the other on the intestinal wall. The roughness value effectively reduces false positives of ulcer detection. Experimental results showed that the proposed method can detect convex and concave parts on the ulcers.

The incidence of Helicobacter pylori and non-steroidal anti-inflammatory drug (NSAID)-negative peptic ulcer disease has increased over the last two decades, especially in the Western world and in countries with low H. pylori infection rates. Idiopathic peptic ulcer disease is a recently described entity which relates to peptic ulcers not caused by H. pylori, NSAID/aspirin therapy, other ulcerogenic organisms and drugs, or other rare malignant and benign diseases. Structural and secreted mucins create the unstirred gastric mucus layer and maintain a stable pH above the gastric mucosa. This mucous layer prevents enzymatic attack by acid and pepsin. Inhibition of cyclooxygenase by NSAID and aspirin inhibits prostaglandin production, inhibits mucin and bicarbonate secretion, and exposes the mucosa to the toxic effects of acid and intragastric enzymes. There is also a complex relationship between H. pylori and different mucin subtypes which on one hand facilitates mucin invasion but on the other hand protects the gastric mucosa. Genetic and epigenetic changes in the mucin molecule may be responsible for idiopathic peptic ulcer disease, but this hypothesis must be further investigated. Herein, the mucin hypothesis of idiopathic peptic ulcer disease is explored.

Full Text Available Until 2030 the ulcer mortality will have a growing trend as estimated by the World Health Organization. Detection of countries and population groups with high risks for the ulcer mortality is possible using forecast method. The authors made a forecast of mortality rate from complicated ulcer disease in males and females and their age groups (15-24, 25-34, 35-54, 55-74, over 75, 15 - over 75 in our country. The study included data of the World Health Organization Database from 1991 to 2012. The work analyzed absolute all-Ukrainian numbers of persons of both genders died from the ulcer causes (К25-К27 coded by the 10th International Diseases Classification. The relative mortality per 100 000 of alive persons of the same age was calculated de novo. The analysis of distribution laws and their estimation presents a trend of growth of the relative mortality. A remarkable increase of deaths from the ulcer disease is observed in males and females of the age after 55 years old. After the age of 75 years this trend is more expressed.

Genital ulcer disease (GUD) is a risk factor in the transmission of human immuno deficiency virus (HIV). The goal of this study is to estimate proportion, identify risk factors, and improve prevention and control of GUD. This is a retrospective study of 211 cases of GUD seen between 1993 and 1997 in an urban public sexually transmitted disease (STD) clinic. Genital ulcers form 7.6% of all STDs seen. Overall, genital herpes was commonest (89 or 42.25%). It was the predominant infection (84 or 44.7%) in the males, while lymphogranuloma venereum (52 or 24.7%) was in females. The peak incidence in both sexes occurred in the 20-29 age group. Males out numbered females by a ratio of 8:1. Most of the patients were single 114 (68.3%) and most 70 or 33.3% were students. Risk markers identified were: casual sex (103 or 53.5%) and multiple sexual partners (77 or 36.5%). Both were significantly higher (P < 0.05) in single patients. Self-treatment, use of multiple drugs and incomplete course of antibiotics were also common. The need to intensify STDS education programmes to all occupational groups and to students in particular is highlighted. Commercial sex workers require periodic education, screening and treatment.
Full Text Available Background and Objectives. Genital ulcer diseases represent a diagnostic dilemma, especially in India, where few STI clinics have access to reliable laboratory facility. The changing STI trends require that a correct diagnosis be made in order to institute appropriate treatment and formulate control policies. The objective of this study was to determine recent trends in aetiology of genital ulcers, by using accurate diagnostic tools. Methods. Specimens from 90 ulcer patients were processed for dark field microscopy, stained smears, culture for H. ducreyi, and real-time PCR. Blood samples were collected for serological tests. Results. Prevalence of GUD was 7.45 with mean age at initial sexual experience as 19.2 years. Use of condom with regular and nonregular partners was 19.5% and 42.1%, respectively. Sexual orientation was heterosexual (92.2% or homosexual (2.2%. There were 8 cases positive for HIV (8.9%. Herpes simplex virus ulcers were the commonest, followed by syphilis and chancroid. There were no cases of donovanosis and LGV. Conclusions. A valuable contribution of this study was in validating clinical and syndromic diagnoses of genital ulcers with an accurate aetiological diagnosis. Such reliable data will aid treatment and better define control measures of common agents and help eliminate diseases amenable to elimination, like donovanosis.

Diabetic patients are at high risk of foot ulcerations that may lead to limb amputations with important socio-economic impact. Peripheral vascular disease may be frequently associated in diabetes mellitus type II with its main symptom, intermittent claudication. Many studies reported the known efficacy of cilostazol in treating vascular claudication. Metalloproteinase-9 (MMP-9) seems to be a biochemical marker implicated in chronic wounds and in particular in diabetic foot ulcers. Cilostazol appears to have a lowering effect on MMP-9 levels and this may suggest a beneficial effect in order to prevent or retard the onset of foot ulcer in diabetic patients. In our study, two groups of diabetic patients with peripheral vascular disease were divided into two groups according to the presence of claudication in order to receive cilostazol. Group A (31 patients without claudication) were not eligible to receive cilostazol whereas Group B (47 patients with claudication) received cilostazol administration for 24 weeks (100 mg orally twice daily). Median follow up was of 16 months. During the follow up, 4·25% of patients of Group B and 35·48% of patients of Group A (P ulceration. Although further randomised and controlled studies are required cilostazol seems to show beneficial effects for primary prevention of diabetic foot ulcers.
Full Text Available Raymond SY Tang, Justin CY Wu Institute of Digestive Disease, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, New Territories, Hong Kong Abstract: Peptic ulcer disease (PUD and gastroesophageal reflux disease (GERD are not uncommon in elderly patients. Clinical presentations of these acid-related disorders may be atypical in the geriatric population. Older individuals are at increased risk for poor outcomes in complicated PUD and for development of GERD complications. Multiple risk factors (eg, Helicobacter pylori [HP], use of nonsteroidal anti-inflammatory drugs [NSAIDs], aspirin contribute to the development of PUD. Recent data has shown that HP-negative, NSAID-negative idiopathic peptic ulcers are on the rise and carry a higher risk of recurrent ulcer bleeding and mortality. Effective management of PUD in the geriatric population relies on identification and modification of treatable risk factors. Elderly patients with GERD often require long-term acid suppressive therapy. Proton pump inhibitors (PPI including esomeprazole are effective in the treatment of reflux esophagitis, maintenance of GERD symptomatic control, and management of PUD as well as its complications. Potential safety concerns of long-term PPI use have been reported in the literature. Clinicians should balance the risks and benefits before committing elderly patients to long-term PPI therapy.

BACKGROUND Peptic ulcer disease is a multifactorial health problem affecting almost all populations worldwide. Large scale population-based studies are crucial to understanding its scope and specifications in various nations. We aimed to explore environmental risk factors of peptic ulcer disease in the first population based study in Ardabil, Northwest Iran. METHODS This study was a part of a larger survey on upper gastrointestinal tract health conducted in Ardabil and Meshkinshahr with a total catchment area population of 600,000 persons during 2000-01. Using a random sampling proportional to place of residence, 1122 persons aged 40 or elder were selected. 1011 (90.1%) accepted participation and underwent a comprehensive medical examination and a systematic upper gastrointestinal endoscopy. Point prevalence of peptic ulcers was correlated to various life style risk factors. RESULTS Gastric and duodenal ulcers were identified in 33 (3.26%) and 50 (4.94%) participants, making an overall prevalence of 8.20%. Based on multivariable logistic regression analyses, H.pylori infection (OR 3.1, 95% CI: 2.1-4.7), Smoking (OR 1.8, 95% CI: 1.1-6.8), and chronic intake of NSAIDs (OR 2.8, 95% CI: 1.3-4.4) were main risk factors of gastric ulcer. For duodenal ulcer, in addition to H.pylori infection (OR 5.6, 95% CI: 1.9-8.8) and Smoking (OR 2.3, 95% CI: 1.4-6.5), male gender (OR 3.6, 95% CI: 1.2-5.8) and living in an urban area (OR 1.9, 95% CI: 1.1-5.2) were among significant risk factors. CONCLUSION This is the first population-based endoscopic study in North West of Iran reporting accurate point prevalence of peptic ulcer disease. The rate of 3.3% for gastric ulcer and 4.9% for duodenal ulcers are substantially lower than the estimates reported in Asian population-based endoscopic studies but higher than European reports.

Objectives: To investigate the etiology of genital ulcerdisease (GUD) among patients attending sexuallytransmitted disease (STD) clinics in Guangzhou, China.Methods: Between September 8, 1998, and August 9,2001, 267 patients with a genital ulcer were clinicallyassessed. Clinical etiology of GUD was dependent onphysical appearance and microbiologic examination,including the following: dark field microscopy and serologyfor Treponema pallidum (TP), swabs of genital ulcer forHerpes simplex virus (HSV), processed quantitativefluorescent polymerase chain reaction (QF-PCR) forsimultaneous detection of HSV, TP, Haemophilus ducreyi(HD), Human papillomavirus (HPV), and serology for HIVinfection.Results: Two hundred thirty men and thirty-sevenwomen with a median age of 33.4 (range 16-74 years) wereanalyzed. The etiology of GUD was syphilis (26.59%)(71/267), genital herpes (17.60%) (47/267), condylomataacuminata (4.87%) (13/267), candidiasis (3.37%) (9/267),bacterial infection (3.75%) (10/267), and multiple infection(6.74%) (18/267). The seroprevalence of HIV was 0.75%(2/267). No etiology was identified in 50.56% (135/267).Conclusion: The etiology of GUD among STD patients inour area was multifactorial with a predominance of syphilisand genital herpes. Based on this limited data obtained atSTD clinics, HIV infection was not common.

Despite decreasing Helicobacter pylori prevalence, the prevalence of peptic ulcer disease is increasing in the aged population, mainly due to increasing use of NSAIDs to manage pain and inflammation. In addition, low dose aspirin is employed as an anti-coagulant for those who have suffered or are at high risk of ischemic stroke and cardiovascular disease. However, NSAIDs and aspirin are injurious to mucosa of stomach and duodenum. NSAID-induced inhibition of mucosal prostaglandin synthesis is thought to be a major mechanism of gastrointestinal mucosal injury. The proportion of elderly has increased rapidly in Korea, with the proportion over 65 years old expected to be 24.3% in 2030. In this higher-risk population, the strategy to reduce the incidence of NSAID-related peptic ulcers and complications such as bleeding, obstruction and perforation is very important. Proton pump inhibitors (PPIs) with cyclooxygenase-2 inhibitor can be used for reducing the risk of NSAID-related ulcers and upper gastrointestinal (GI) complications. However, continuous use of PPI has several problems. In addition, NSAID-related problems in the lower GI tract have increased, in contrast to the decrease of NSAID-related upper GI disease. The aim of this review is to provide an evidence-based knowledge regarding the mechanism, complications of treatment, and prevention strategies for NSAID- or aspirin-related peptic ulcer disease in Korea.

Traditional knowledge of clinical, laboratorial, and endoscopic orders regarding ulcerative colitis and Crohn's disease has begun to be implemented by the revolutionary data from genetic studies. Ever since many decades ago it has been clear that inflammatory bowel diseases are complex multifactorial disorders wherein gut-confined and/or environmental factors must synergize with genetic components to effect the full-blown disorder. The sequencing of the human genome and the generation of public resources of single nucleotide polymorphisms permitted the conduction of powerful population based genome-wide association studies. The latter have increased the number of the identified susceptibility loci to 99. In this review we touched on two pathways that make true susceptibility genes for inflammatory bowel diseases; gene loci that confer specific risk for ulcerative colitis and Crohn's disease were discussed in detail.

Peptic ulcer disease is a chronic disease of the gastrointestinal tract, mainly manifesting itself in the formation of the fairly persistent ulcer defect of the mucous membrane of the stomach and/or duodenum. Association analysis of common polymorphisms of matrix metalloproteinases genes MMP-1 (rs1799750, rs494379), MMP-2 (rs2285052), MMP-3 (rs3025058), MMP-9 (rs3918242, rs17576), and MMP-12 (rs2276109) and their tissue inhibitors TIMP-2 (rs8179090) and TIMP-3 (rs9619311) was carried out in 353 patients with a gastric ulcer or duodenal ulcer and in 325 unrelated healthy individuals from the Republic of Bashkortostan. Associations of polymorphic variants rs1799750 and rs494379 of gene MMP-1, rs3025058 of gene MMP-3, rs3918242 and rs17576 of gene MMP-9, and rs9619311 of gene TIMP-3 with the risk of peptic ulcer disease in Russians and Tatars were revealed.

Endoscopy is currently the primary diagnostic technique for inflammatory bowel disease (IBD) in children. To assess the accuracy of US and dynamic contrast-enhanced MRI for diagnosing inflammatory bowel disease and for distinguishing Crohn disease and ulcerative colitis in comparison to a reference standard. Consecutive children with suspected IBD underwent diagnostic workup including ileocolonoscopy and upper gastrointestinal endoscopy as the reference standard, abdominal US, and MR enterography and colonography at 3 T. The protocol included a dynamic contrast-enhanced 3-D sequence. Sensitivity, specificity and kappa values were calculated for one ultrasonographer and two MRI observers. We included 28 children (15 boys) with mean age 14 years (range 10-17 years). The diagnosis was IBD in 23 children (72%), including 12 with Crohn disease, 10 with ulcerative colitis and 1 with indeterminate colitis. For the diagnosis of inflammatory bowel disease the sensitivity was 55% for US and 57% (both observers) for MR entero- and colonography, and the specificity was 100% for US and 100% (observer 1) and 75% (observer 2) for MR entero- and colonography. Combined MRI and US had sensitivity and specificity of 70% and 100% (observer 1) and 74% and 80% (observer 2), respectively. With the addition of a dynamic contrast-enhanced MR sequence, the sensitivity increased to 83% and 87%. US and MRI could only distinguish between Crohn disease and ulcerative colitis when terminal ileum lesions were present. US and MR entero- and colonography have a high accuracy for diagnosing inflammatory bowel disease in children but cannot be used to distinguish Crohn disease and ulcerative colitis. (orig.)

Peptic ulcer disease including both gastric and duodenal ulcer form a substantial part of patients seeking surgical opinion world-wide. The concept of acid in peptic ulcer disease, which was the basis of treatment of peptic ulcer was revolutionized by the discovery of H2-receptor antagonists, that led to the principle of acid suppression therapy for duodenal ulcer which followed decades of preference for surgical interventions in the form of gastric resections, vagotomy etc., After the discovery of Helicobacter pylori organism as the causative factor a triple drug regime was identified to treat peptic disease which was further modified to sequential therapy to avoid antibiotic resistance. This recognition has not concluded the chapter on peptic ulcers. The management of ulcer disease and its complications remain a surgical challenge. All the materials for this review have been accessed from various internet search engines. The references have been narrowed down to 34 by excluding cross references, duplicated citations, pediatric studies, case reports, iatrogenic and malignant perforations and including microbiological, immunohistochemistry references and studies with more than a sample size of ten. Case control, cohort studies, prospective/retrospective, metaanalytical studies were preferred in that order. This article attempts to take an overview of all aspects of the management of peptic ulcer.

Crohn disease (CD) and ulcerative colitis (UC), the two main types of inflammatory bowel disease (IBD), have become increasingly common in Australasian children and adolescents in recent years. Furthermore, CD and UC are seen more often in younger children. These conditions are typically more extensive in children and tend to follow more severe disease courses than in adults. Although many children may present with typical symptoms (such as abdominal pain or bloody diarrhoea), others have atypical features (including oral ulceration, short stature or skin manifestations). In addition, many children with IBD will have altered growth or nutrition, which may compromise normal linear growth and pubertal development. Early identification and full assessment of children presenting with possible IBD are essential to avoid consequences of diagnostic delay and to optimise short- and long-term outcomes. Management of IBD encompasses various options and should be undertaken within a team-based, child and family-focused, multidisciplinary setting.

Full Text Available Abstract Riga Fede disease is a reactive mucosal disease as a result of repetitive trauma of the tongue by the anterior primary teeth during forward and backward movement. Although the aspect of the lesion might be impressive, its nature is relatively benign. The history and clinical features are most often so typical that there is seldom a need for addititonal histopathological examination. Riga Fede disease can most often be treated with conservative measures only. Beside the presentation of a six-month-old boy with Riga Fede disease, the literature has been reviewed as well. From this review it can be concluded that Riga Fede disease is almost exclusively restricted to the tongue, occurs soon after birth when associated with (neonatal teeth, has a male predilection, and is in one quarter of the cases associated with neurologic disorders. In the later case, Riga Fede disease develops after the age of 6 months.

Epstein Barr virus (EBV) positive mucocutaneous ulcers (EBVMCU) form part of a spectrum of EBV-associated lymphoproliferative disease. They have been reported in the setting of immunosenescence and iatrogenic immunosuppression, affecting the oropharyngeal mucosa, skin and gastrointestinal tract (GIT). Case reports and series to date suggest a benign natural history responding to conservative management, particularly in the GIT. We report an unusual case of EBVMCU in the colon, arising in the setting of immunosuppression in the treatment of Crohn's disease, with progression to Hodgkin lymphoma 18 mo after cessation of infliximab. The patient presented with multiple areas of segmental colonic ulceration, histologically showing a polymorphous infiltrate with EBV positive Reed-Sternberg-like cells. A diagnosis of EBVMCU was made. The ulcers failed to regress upon cessation of infliximab and methotrexate for 18 mo. Following commencement of prednisolone for her Crohn's disease, the patient developed widespread Hodgkin lymphoma which ultimately presented as a life-threatening lower GIT bleed requiring emergency colectomy. This is the first report of progression of EBVMCU to Hodgkin lymphoma, in the setting of ongoing iatrogenic immunosuppression and inflammatory bowel disease.

Chronic ulcerative stomatitis is an immune-mediated mucocutaneous disorder characterized clinically by erosions or ulcers. Most cases are limited to the mouth. The histopathological features are non-specific or mimic those of oral lichen planus, and studies by immunoflorescent microscopy are essential for definitive diagnosis. The defining immunopathogenic mechanism is the binding of IgG to the nuclear protein deltaNp63alpha of keratinocytes in the basal and parabasal cell layers of the oral stratified epithelium. DeltaNp63alpha functions as a regulator of epithelial stem cell activity and as an anti-apoptotic agent, and regulates the expression of cell-to-cell and cell-to-basement membrane adhesion molecules. The autoimmune IgG-deltaNp63alpha interaction is thought to result in damage to the structural attachment of keratinocytes to one another and to the epithelial basement membrane zone, and in dysregulation of the cell cycle and apoptosis of basal keratinocytes with the development of erosions or ulcers. The aims of treatment are to suppress the pathogenic immuno-inflammatory responses, to prevent local infection and to promote healing. The purpose of this article is to provide a succinct review of the diagnostic, clinical and aetiopathogenic features of, and treatment guidelines for chronic ulcerative stomatitis, and to argue that this disease should be regarded as a variant of oral lichen planus, rather than as a distinct entity.

This systematic review examines the evidence for commonly employed strategies of managing patients with recurrent ulcer disease after acid-reducing operations. Particular attention is given to recent evidence relating Helicobacter pylori (H. pylori ) and nonsteroidal anti-inflammatory drugs (NSAIDs) to ulcer recurrence after operative therapy. MEDLINE word searches of the literature from 1966 to 2001 identified 895 articles that cross-reference the terms "peptic ulcer disease (PUD)," "surgery," and "recurrence." Articles were selected for systematic review of evidence relating incomplete vagotomy, NSAIDs, and H. pylori to postoperative ulcer recurrence and evidence supporting common medical and surgical strategies. The relationship between incomplete vagotomy and recurrent ulcer disease is suggested by randomized controlled trials and well-designed prospective case series. The evidence that NSAID use is an important pathogenic factor in recurrent ulcer disease includes the relationship between NSAIDs and primary PUD, the occurrence of NSAID-induced ulcers in patients taking proton pump inhibitors, and case series demonstrating virulent ulcer disease in patients taking aspirin despite prior acid-reducing operations. The relationship between H. pylori infection and postoperative ulcer recurrence remains uncertain despite multiple controlled trials and well-designed case series that have documented high rates of H. pylori infection in postoperative patients. The initial management of patients with recurrent ulcer disease after acid-reducing operations consists of a protein pump inhibitor or a histamine-2 receptor antagonist and antibiotics directed at H. pylori, if present. Evidence for this regimen includes prospective randomized trials demonstrating the efficacy of cimetidine in healing ulcers after acid-reducing operations and prospective, randomized studies documenting the efficacy of histamine-2 receptor antagonists and protein pump inhibitors in the management

Forty-five patients with Helicobacter pylori (HP)-associated gastritis or ulcer disease were included in this study. Radionuclide-labelled solid meals were used to calculate gastric emptying times (GETs) and carbon-14 urea breath tests ([sup 14]C UBTs) were used to measure the HP colonies quantitatively. The patients were assessed according to the following two criteria: (a) the HP colony number (i.e. high or low) and (b) the recorded duration of the GET (i.e. long or short). There was no statistically significant difference in the incidence of abnormal GET between high and low [sup 14]C UBT patients or in the incidence of abnormal [sup 14]C UBT between long and short GET cases. In conclusion, no significant relationship between HP-associated gastritis or ulcer disease and GET was found in this study. (orig.)

Helicobacter pylori infection plays an important role in the pathogenesis of peptic ulcer disease (PUD). Several factors have been proposed as possible H. pylori virulence determinants; for example, bacterial adhesins and gastric inflammation factors are associated with an increased risk of PUD. However, differences in bacterial virulence factors alone cannot explain the opposite ends of the PUD disease spectrum, that is duodenal and gastric ulcers; presumably, both bacterial and host factors contribute to the differential response. Carriers of the high-producer alleles of the pro-inflammatory cytokines IL-1B, IL-6, IL-8, IL-10, and TNF-α who also carry low-producer allele of anti-inflammatory cytokines have severe gastric mucosal inflammation, whereas carriers of the alternative alleles have mild inflammation. Recent reports have suggested that the PSCA and CYP2C19 ultra-rapid metabolizer genotypes are also associated with PUD.

Full Text Available Abstract Background Ulcerative colitis disease activity is determined by measuring symptoms and signs. Our aim was to determine which symptom domains are frequent and responsive to change in the evaluation of disease activity, which are those defined by three criteria: 1 they occur frequently during flares; 2 they improve during effective therapy for ulcerative colitis; and 3 they resolve during remission. Methods Twenty-eight symptom domains, 16 from standard indices and 12 novel domains identified by ulcerative colitis patient focus groups, were evaluated. Sixty subjects with ulcerative colitis were surveyed, rating each symptom on the three criteria with a 100 mm Visual Analogue Scale. Frequent and responsive symptoms were defined a priori as those whose median Visual Analogue Scale rating for all 3 criteria was significantly greater than 50. Results Thirteen of the 28 symptom domains were identified as both frequent in ulcerative colitis flares and responsive to changes in disease activity. Seven of these 13 symptom domains were novel symptoms derived from ulcerative colitis patient focus groups including stool mucus, tenesmus, fatigue, rapid postprandial bowel movements, and inability to differentiate liquid or gas from solid stool when rectal urgency occurs. Ten of the 16 symptom domains from standard indices were either infrequent or unresponsive to changes in disease activity. Conclusion Only some of the symptoms of ulcerative colitis that are important to patients are included in standard indices, and several symptoms currently measured are not frequent or responsive to change in ulcerative colitis patients. Development of survey measures of these symptom domains could significantly improve the assessment of disease activity in ulcerative colitis.

Buruli ulcer, caused by infection with Mycobacterium ulcerans, is a necrotizing disease of the skin and subcutaneous tissue, which is most prevalent in rural regions of West African countries. The majority of clinical presentations seen in patients are ulcers on limbs that can be treated by eight weeks of antibiotic therapy. Nevertheless, scarring and permanent disabilities occur frequently and Buruli ulcer still causes high morbidity. A vaccine against the disease is so far not available but would be of great benefit if used for prophylaxis as well as therapy. In the present study, vesicular stomatitis virus-based RNA replicon particles encoding the M. ulcerans proteins MUL2232 and MUL3720 were generated and the expression of the recombinant antigens characterized in vitro. Immunisation of mice with the recombinant replicon particles elicited antibodies that reacted with the endogenous antigens of M. ulcerans cells. A prime-boost immunization regimen with MUL2232-recombinant replicon particles and recombinant MUL2232 protein induced a strong immune response but only slightly reduced bacterial multiplication in a mouse model of M. ulcerans infection. We conclude that a monovalent vaccine based on the MUL2232 antigen will probably not sufficiently control M. ulcerans infection in humans.

Despite so much contributions reported in the literature, the aetiology of the duodenal ulcer remains an enigmatic subject to the medical profession. Findings of Helicobacter pylori seem to have overshadowed the real issue, in that, how a small area of the duodenal mucosa could be inflicted with the acid-pepsin injury has not been questioned? One hundred and sixty-eight consecutive patients, presented with epigastric pain were included in the endoscopic study. The aim of the study was to find out the prevalence and its clinical importance on the sizes of the pyloric aperture in the aetiology of peptic ulcer disease. Demographic data on the sizes of the pyloric aperture were divided into two groups, in that, those up to 3 mm in diameter were included in one and those over the size of 3 mm in another. Among the 168 cases, the gastric ulcer was found in 12 and duodenal ulcer in 27 patients. The sex ratio of men to women was 1.4:1 found in the former and 8:1 in the latter. Among other findings, a knuckle of duodenal mucoa was noticed prolapsing through the large pyloric aperture. It could be postulated that a knuckle of the mucosa that keeps peeping through the pylorus acts as a mucosal plug in empty stomach, like a cork in the acid bottle. The main physiological function is to protect the mucosa from being damaged by the acid-pepsin injury or by the reflux of bile, but the tip of the plug seems to be subjected to such injury. Furthermore, the surface epithelial cells could also be subjected to ischaemic change while prolapsing through the pylorus. This may lead to reduced production of the mucosal gel and bicarbonate secretion, thus exposing the damaged mucosa to acid bath. This supports the concept, how a small area of the stomach or duodenum could be inflicted with ulceration.

The efficacy and safety of 75 mg of roxatidine acetate at night as maintenance treatment for chronic peptic ulcer disease was investigated in two double-blind randomized placebo-controlled multicenter studies. A total of 725 patients with endoscopic demonstration of a healed ulcer were recruited; 420 patients were enrolled by 28 centers in the duodenal ulcer study and 305 patients were enrolled by 24 centers in the gastric ulcer study. The duration of treatment in each study was 12 months. The primary efficacy endpoint was ulcer relapse, confirmed on scheduled endoscopy at two, four, six, nine, and 12 months or as necessitated clinically. The total ulcer recurrence rate was significantly lower in patients on active treatment: 35% and 32% of patients with a previously healed duodenal or gastric ulcer relapsed within 12 months while on roxatidine acetate, compared with 66% and 71% of patients in each study on placebo (life-table analysis, P = 0.0001). Both active and placebo treatments were well tolerated. There was no evidence of any clinically significant drug-related laboratory abnormalities, electrocardiographic changes, or changes in vital signs with either treatment. It is concluded that 75 mg of roxatidine acetate at night is a safe and effective maintenance treatment to sustain remission in patients with peptic ulcers.

The association of Helicobacter pylori eradication with the occurrence of renal dysfunction in patients with peptic ulcer diseases is still unclear. This study aimed to clarify the relevance of H. pylori eradication to the occurrence of chronic kidney diseases in patients with peptic ulcer diseases. Data that were available from 2000–2011 were extracted from the National Health Insurance Research Database in Taiwan, and all patients with peptic ulcer diseases (n = 208 196) were screened for eligibility. We divided randomly selected patients into an H. pylori eradication cohort (cohort A, n = 3593) and matched them by age and sex to a without H. pylori eradication cohort (cohort B, n = 3593). Subgroup analysis was further performed for H. pylori eradication within ≤ 90 days of the diagnosis date (early eradication, n = 2837) and within 91–365 days (non-early eradication, n = 756). Cox proportional hazards regression analysis was used to estimate the association of H. pylori eradication with the risk of developing chronic kidney diseases and mortality. We observed that there were more patients suffering from chronic kidney disease in cohort B than in the early eradication subgroup of cohort A (8.49% vs. 6.70%, respectively, p = 0.0075); the mortality rate was also higher in cohort B (4.76% vs. 3.70%, respectively, p = 0.0376). Old age, pulmonary disease, connective tissue disorders, and diabetes were risk factors for chronic kidney diseases but early H. pylori eradication was a protective factor against chronic kidney diseases (hazard ratio: 0.68, 95% confidence interval: 0.52–0.88, p = 0.0030), and death (hazard ratio: 0.69, 95% confidence interval: 0.49–0.96, p = 0.0297). In conclusion, our findings have important implications suggesting that early H. pylori eradication is mandatory since it is associated with a protective role against the occurrence of chronic kidney diseases.

Over the past two decades, surgery for complicated peptic ulcer disease has evolved to a "less-is-more" approach due predominately to improved medical therapy. This study sought to determine whether a nonresective operative strategy has been an effective and prudent approach. A 20-year retrospective evaluation was conducted to compare outcomes of patients from the first decade (1990-1999) with those from the more recent decade (2000-2009). In all, 50 patients underwent surgery for complications of peptic ulcer disease, 36 in the early period and 14 in the later period, with 94 per cent being urgent or emergent. Acid-reducing procedures (vagotomy) decreased significantly from 29 to 7 over the two periods (P = 0.04), as did gastric resections from 23 to 3 (P = 0.01). The prevalence of H. pylori and use of NSAIDs both increased from 28 per cent to 36 per cent and 31 per cent to 43 per cent, respectively. Postoperative mortality remained unchanged, 22 per cent vs. 7 per cent (P = 0.41) over the two periods. Resections and definitive acid-reducing procedures continue to decline with no increase in adverse outcomes. This more moderate operative approach to complicated peptic ulcer surgery is appropriate given the trend towards lower mortality and improved medical treatment. In our high-risk veteran population, overall perioperative mortality, length of stay, and reoperations have been reduced.

Peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD) are not uncommon in elderly patients. Clinical presentations of these acid-related disorders may be atypical in the geriatric population. Older individuals are at increased risk for poor outcomes in complicated PUD and for development of GERD complications. Multiple risk factors (eg, Helicobacter pylori [HP], use of nonsteroidal anti-inflammatory drugs [NSAIDs], aspirin) contribute to the development of PUD. Recent data has shown that HP-negative, NSAID-negative idiopathic peptic ulcers are on the rise and carry a higher risk of recurrent ulcer bleeding and mortality. Effective management of PUD in the geriatric population relies on identification and modification of treatable risk factors. Elderly patients with GERD often require long-term acid suppressive therapy. Proton pump inhibitors (PPI) including esomeprazole are effective in the treatment of reflux esophagitis, maintenance of GERD symptomatic control, and management of PUD as well as its complications. Potential safety concerns of long-term PPI use have been reported in the literature. Clinicians should balance the risks and benefits before committing elderly patients to long-term PPI therapy.

The authors point out the striking significance of coloscopy in establishing a correct diagnosis of inflammatory diseases of the colon. In particular, the most valuable endoscopic features are indicated which may permit distinguishing between idiopathic ulcerative colitis and Crohn's disease of the colon. Differentiation between these two diseases cannot always be achieved by means of available diagnostic procedures other than coloscopy. Moreover, the endoscopic findings enable an assessment to be made of the extent, stage, severity and course of either disease. The authors' experience encompass 2,478 coloscopy examinations: the observed cases of idiopathic ulcerative colitis are 182, those of Crohn's disease of the colon are 104.

A natural outbreak of ulcerative enteritis-like disease associated with Clostridium sordellii was diagnosed in two commercial quail flocks. Clinical signs in the quail included anorexia, weakness, and increased mortality in the flocks. Lesions in the intestine were characterized by ulcers covered with fibrinonecrotic exudate in the small intestine and occasional hemorrhages. There were also multifocal pale areas of necrosis in the liver. Clostridium sordellii was isolated from the intestine and liver. A retrospective study of avian cases submitted to the California Animal Health and Food Safety Laboratories revealed that C. sordellii had been isolated in 45 avian submissions, most commonly in chickens and turkeys. In most of these cases the birds were diagnosed with necrotic enteritis, with or without hepatitis. Clostridium sordellii has occasionally been associated with gangrenous dermatitis in poultry, but this is the first report of enteritis in an avian species.

Prospective population-based studies have allowed a re-evaluation of the risks of insuring patients with ulcerative colitis or Crohn's disease. Life expectancy, the risk of cancer and working capacity are very much better than previously recognised and are normal for many patients. Three population-based studies in ulcerative colitis have shown a mortality similar to or slightly less than the general population except in the first year after diagnosis, whilst two have shown a slightly higher mortality (standardized mortality ratio, SMR = 1.4), except for those with proctitis. In Crohn's disease, two population-based studies have also shown an increased mortality (SMR = 1.4), which is similar to that of unskilled manual labourers (SMR = 1.43) from all causes of death. Three other studies have shown no increase in overall mortality, except in the first 5 years after diagnosis, in those with proximal small intestinal disease and in some patients needing multiple operations. Insurance risks should be evaluated on an individual basis, after details of the extent and pattern of disease have been obtained. Although the 'standard life' in insurance terms differs from that of the general population, because people who seek life assurance are self-selected from a more affluent section of society, many patients can be identified who have a particularly good prognosis. These include patients with ulcerative proctitis, those with left-sided colitis in extended remission (> 12 months), and patients more than 30 years old with localized ileal or ileocaecal Crohn's disease that has responded to treatment. From the published data, it is difficult to justify increasing the insurance premium in such patients.

Full Text Available Thromboangiitis obliterans (TAO or Buerger's disease is associated with both distal ulcers in the extremities and the possibility of amputation. The only treatment that has been shown to be effective in TAO is complete abstention from smoking. In spite of this, the disease progresses in up to 30 percent of cases and finally results in limb amputation. Only a few pharmacological and surgical options are available to date to improve healing ulcers in TAO. The efficacy of prostaglandin analogues is controversial. This paper summarizes the current evidence for medical treatment with bosentan in chronic ulcers in TAO patients. These available data up to date allow us to conclude that the beneficial effects of bosentan on improving endothelial function, inflammatory processes, and selective vasodilatation of damaged vessels result in a clinical enhancement regarding healing and preventive digital ulcers in such patients. In any case, these promising findings have to be confirmed with larger randomised trials.

The burden of diabetic foot disease (DFD) is expected to increase in the future. The incidence of DFD is still rising due to the high prevalence of DFD predisposing factors. DFD is multifactorial in nature; however most of the diabetic foot amputations are preceded by foot ulceration. Diabetic peripheral neuropathy (DPN) is a major risk factor for foot ulceration. DPN leads to loss of protective sensation resulting in continuous unconscious traumas. Patient education and detection of high ris...
The bacterium Helicobacter pylori is one of the main causes of peptic ulcers. But how was this causal relationship demonstrated? A historical and philosophical analysis of a series of studies conducted during the 1980s can elucidate the question. In the beginning, a mere correlation between the newly discovered bacterium and peptic ulcers was found in gastric biopsies. It remained an open question whether the bacterium caused the disease, or whether it constituted merely an opportunistic infection. Yet determining the direction of causality was difficult in the absence of an animal model: Even though gastritis was observed in a courageous self-experiment involving a swallowed bacterial culture, tf!e significance of the individual case was small. The failings of the self-experiment could only be rectified by a randomised, placebo-controlled trial which met the requirements of Koch's third postulate. Moreover, it was necessary to gain an initial understanding of the mechanism by which the causal relationship between H. pylori and peptic ulcers is mediated: How, forexample, does the bacterium survive in the acid environment of the stomach? The study of the case from the perspective of the history and philosophy of science illustrates how medical knowledge is established incrementally.

AIM: To investigate the prevalence and risk factors of asymptomatic peptic ulcer disease (PUD) in a general Taiwanese population. METHODS: From January to August 2008, consecu-tive asymptomatic subjects undergoing a routine health check-up were evaluated by upper gastrointestinal en-doscopy. Gastroduodenal mucosal breaks were carefully assessed, and a complete medical history and demo-graphic data were obtained from each patient. Logistic regression analysis was conducted to identify indepen-dent risk factors for asymptomatic PUD. RESULTS: Of the 572 asymptomatic subjects, 54 (9.4%) were diagnosed as having PUD. The prevalence of gas-tric ulcer, duodenal ulcer and both gastric and duode-nal ulcers were 4.7%, 3.9%, and 0.9%, respectively. Multivariate analysis revealed that prior history of PUD [odds ratio (OR), 2.0, 95% CI: 1.3-2.9], high body mass index [body mass index (BMI) 25-30: OR, 1.5, 95% CI: 1.0-2.2; BMI > 30 kg/m2: OR, 3.6, 95% CI: 1.5-8.7] and current smoker (OR, 2.6, 95% CI: 1.6-4.4) were in-dependent predictors of asymptomatic PUD. In contrast, high education level was a negative predictor of PUD (years of education 10-12: OR, 0.5, 95% CI: 0.3-0.8; years of education > 12: OR, 0.6, 95% CI: 0.3-0.9).CONCLUSION: The prevalence of PUD in asymptom-atic subjects is 9.4% in Taiwan. Prior history of PUD, low education level, a high BMI and current smoker are independent risk factors for developing asymptomatic PUD.
Full Text Available Introduction: To meet key millennium development goals, the rural population needs to be reached for health assessment and service delivery. Gastroduodenal ulcer disease is a common ailment affecting the health of people in Uganda. A cross-sectional study was conducted at Bwera Hospital in Kasese district of western Uganda, to establish the prevalence and predisposing factors of Helicobacter pylori among gastroduodenal ulcer disease patients. Methods: A sample of 174 patients with symptoms of gastroduodenal ulcer disease was purposively obtained. Using two laboratory test methods, the prevalence of H. pylori among these patients was determined. A structured questionnaire was administered to participants to establish their demographic background and selected aspects of their lifestyle. Finally, the results obtained by enzyme-linked immunosorbent assay (ELISA and immunochromatographic rapid test (IRT were compared. Results: We established the prevalence of H. pylori as 29.9% (52/174 by ELISA and 37.4% (65/174 by IRT. Cigarette smoking, poor sanitation, and lack of formal education were the significant predisposing factors with p-values <0.05. The two tests gave identical results in 87.9% of the patients. Discussion: The prevalence of H. pylori by IRT and ELISA test methods was similar to what has been reported elsewhere in developed countries; but was lower than previously reported in developing countries including Uganda. The previous studies in Uganda were carried out in the urban population and on young children; and some used antibody-detection methods only, therefore leading to different prevalence as a result of difference in study population and methods.

Noninfectious genital ulcers are much more common than ulcers arising from infections. Still, it is important to take a thorough history of sexual activity and a sexual abuse screen. A physical exam should include skin, oral mucosa, nails, hair, vulva, and vaginal mucosa if needed. The differential diagnosis of noninfectious genital ulcers includes: lipschütz ulcers, complex aphthosis, Behçet's syndrome, vulvar metastatic Crohn's disease, hidradenitis suppurativa, pyoderma gangrenosum, pressure ulcers, and malignancies. It is important to come to the correct diagnosis to avoid undue testing, stress, and anxiety in patients experiencing genital ulcerations.

The incidence of inflammatory bowel disease (IBD) and associated oxidative stress is increasing. The antioxidant mineral selenium (Se) was measured in serum samples from 106 IBD patients (53 with ulcerative colitis (UC) and 53 with Crohn's disease (CD)) and from 30 healthy controls. Serum Se concentrations were significantly lower in UC and CD patients than in healthy controls (p disease and the length of time since onset (p serum Se and cardiovascular status was observed in CD than in UC patients. An adequate nutritional Se status is important in IBD patients to minimize the cardiovascular risk associated with increased inflammation biomarkers, especially in undernourished CD patients, and is also related to an improved nutritional and body iron status.
Full Text Available Endotoxin (lipopolysaccharide, LPS and LPS antibody in the blood were studied in 61 cases of ulcerative colitis (U.C. by radioimmunoassay. Lysozyme (LZM concentration was also studied by the turbidimetric method. As a result, it was found that the blood LPS value as well as serum LZM concentration reflects the clinical observations. The case of endotoxemia in the active phase group showed a positive correlation between the LPS value and LZM concentration. LPS antibody which could not be detected in many cases of the active phase, had a high titer in cases of remission with a long history of the disease. These results would suggest that in U.C. with damaged intestinal mucosal barrier, LPS originating from intestinal flora enters into the blood and aggravates the disease and further that this invading LPS releases LZM into the blood. The same studies were performed on 7 cases of Crohn's disease and the same result was obtained.

Full Text Available Jill MV Petkau, Bertus Eksteen Snyder Institute for Chronic Diseases, Cumming School of Medicine, University of Calgary, Calgary, AB, Canada Abstract: Inflammatory bowel disease (IBD encompasses a cluster of different disease phenotypes which are broadly classified into ulcerative colitis and Crohn's disease. Disease pathogenesis is driven by abnormal host immune responses to their resident gut microbiome in genetically susceptible individuals. Clinical disease features and outcomes are heterogenous and not unexpected as over 163 genetic loci are associated with disease susceptibility, and there are great variability in environmental exposures. Despite this variability, there has been relatively few efficacious therapies for particularly moderate-to-severe IBD. Treatment has been dominated by antitumor necrosis alpha agents with significant success but equally potentially serious adverse events. Therapeutic targeting of leucocyte trafficking has emerged as a viable alternative therapy, with vedolizumab being the lead compound. This review focuses primarily on its biological function as a selective gut immunotherapy, its safety and efficacy, and its emerging role as a mainstream therapy in managing IBD. Keywords: adhesion molecule antagonist, anti-α4β7 integrin, inflammatory bowel disease, leukocyte trafficking, monoclonal antibody, selective gut immunotherapy, tumor necrosis factor alpha
Full Text Available Background: The role of Helicobacter pylori (H. pylori eradication in non-steroidal anti inflammatory drug (NSAID users with peptic ulcer disease is controversial especially in countries with a high prevalence of the infection. Furthermore the value of low dose omeprazole for maintenance of remission is not yet known. Patients and methods: 138 symptomatic out-patients receiving continuous COX 1 NSAID therapy, were treated with omeprazole 40mg/day upon endoscopic confirmation of gastro-duodenal ulceration or erosions while those infected with H. pylori received in addition clarithromycin 500 mg and amoxycillin 1000 mg twice daily during the first week of treatment. After endoscopic confirmation of healing at the end of week 5, the patients were randomized to receive omeprazole 10 mg (n=50 or 20 mg once daily (n=66 and endoscopy repeated after 20 weeks. Results: The overall healing rate (per protocol at five weeks (116/128 was 90.6% while in 85.5% (65/76 eradication was successful. The healing rate for the H. pylori eradicated patients (58/65 was 89.2%. For those who failed eradication (8/11 it was 72.7% (NS, while for patients not infected with H. pylori at entry to the study (50/52 it was 96.2% (NS. An intention to treat analysis showed that after 20 weeks of omeprazole prophylaxis with the 10mg dose 86% (43/50 had maintained healing while for the 20mg dose a similar figure was observed (87.9; 58/66. Only three patients in the two groups (pp had persistent H. pylori infection, all of whom relapsed. No patients discontinued treatment because of adverse effects of the drugs. Conclusion: H. pylori eradication was not associated with impaired ulcer healing in a Middle Eastern population with symptomatic NSAID induced gastro/duodenal lesions, when a high healing dose of omeprazole (40 mg was used. After eradication, omeprazole 10 or 20 mg per day were highly and equally effective for maintenance of gastroduodenal mucosal integrity during continued

The burden of diabetic foot disease (DFD) is expected to increase in the future. The incidence of DFD is still rising due to the high prevalence of DFD predisposing factors. DFD is multifactorial in nature; however most of the diabetic foot amputations are preceded by foot ulceration. Diabetic peripheral neuropathy (DPN) is a major risk factor for foot ulceration. DPN leads to loss of protective sensation resulting in continuous unconscious traumas. Patient education and detection of high risk foot are essential for the prevention of foot ulceration and amputation. Proper assessment of the diabetic foot ulceration and appropriate management ensure better prognosis. Management is based on revascularization procedures, wound debridement, treatment of infection and ulcer offloading. Management and type of dressing applied are tailored according to the type of wound and the foot condition. The scope of this review paper is to describe the diabetic foot syndrome starting from the evaluation of the foot at risk for ulceration, up to the new treatment modalities.

Leg and foot ulcers are symptoms of very different diseases. The aim of this paper is to demonstrate the differential diagnosis of leg ulcers. The majority of leg ulcers occur in the lower leg or foot. In non-venous ulcers the localization in the foot area is more frequent. The most frequent underlying disease is chronic venous disease. In 354 leg ulcers, Koerber found 75.25% venous leg ulcers, 3.66% arterial leg ulcers, 14.66% ulcers of mixed venous and arterial origin and 13.5% vasculitic ulcers. In the Swedish population of Skaraborg, Nelzen found a venous origin in 54% of the ulcer patients. Each leg ulcer needs a clinical and anamnestic evaluation. Duplex ultrasound is the basic diagnostic tool to exclude vascular anomalies especially chronic venous and arterial occlusive disease. Skin biopsies help to find a correct diagnosis in unclear or non-healing cases. In conclusion, chronic venous disease is the most frequent cause of leg ulcerations. Because 25% of the population have varicose veins or other chronic venous disease the coincidence of pathological venous findings and ulceration is very frequent even in non-venous ulcerations. Leg ulcers without the symptoms of chronic venous disease should be considered as non-venous.

Data from baseline surveys and STI/HIV laboratory tests (n=615 men) were used to examine correlates of bacterial ulcers (Treponema pallidum, Haemophilus ducreyi, or Chlamydia trachomatis L1–L3 detected in ulcer) and acute HSV-2 ulcers (HSV-2 positive ulcer specimen, HSV-2 sero-negative, and negative for bacterial pathogens) vs. recurrent HSV-2 ulcers (sero-positive), separately. Compared to men with recurrent HSV-2 ulcers, men with bacterial ulcers had larger ulcers but were less likely to be HIV-positive whereas men with acute HSV-2 ulcers were younger with fewer partners. Acute HIV was higher among men with bacterial and acute HSV-2 ulcers; the difference was not statistically significant. PMID:28217702

Helicobacter pylori causes various diseases such as chronic gastritis, peptic ulcer and gastric cancer. While majority of the people infected with H. pylori is asymptomatic, 15-20 % of them develop such diseases. The main factors, which determine the development of H. pylori related diseases might be bacterial virulence, host genetic and environmental factors.The aim of this study was to reveal the factors that play a role in the disease development in patients with reflux esophagitis and peptic ulcer, infected with Helicobacter pylori. Environmental factors such as medical agents, smoking and body mass index were evaluated. The factors specific to bacteria such as vacA, CagA, babA and iceA virulence genotypes and the host factors such as IL-1, IL-2, IL-4, IL-6, IL-10, IL-12, interferon-γ, TNF-α, ve TGF-β1 gene polymorphisms were compared between the two groups.H. pylori infected twenty five patients with reflux esophagitis and peptic ulcer were enrolled in the study. There was no statistical difference between the two groups regarding environmental factors. IL-2 -330T +166T (p=0.037) and IL10 -1082A; -819C (p=0.049) gene polymorphisms were significantly more common in the group of patients with peptic ulcer compared to the group with reflux esophagitis. In both groups of patients, either with reflux esophagitis or peptic ulcer, multiple H. pylori virulence genotypes (cagA, vacA, babA) (mean values 74 %, 78 %, 54 % respectively) were observed.In this study, we revealed that cytokine gene polymorphisms may play a role in the development peptic ulcer while H. pylori virulence genotypes seem to be crucial for the development of associated diseases (Tab. 4, Ref. 51).
Full Text Available During the years 1985 to 1987, 689 moose (Alces alces L. collected throughout Sweden were necrop-sied at the National Veterinary Institute in Uppsala, Sweden. Sixty-eight of those investigated had catarrhal to hemorrhagic enteritis, atrophied lymphoid organs, and/or numerous erosive, uclerative, necrotizing lesions of the digestive mucosa. Histopathology of the mucous membranes revealed marked inter- and intracellular oedema, erosions, ulcers and intracytoplasmic inclusion bodies. Neither Bovine Virus Diarrhoea/Mucosal Disease (BVD/MD or Infectious Bovine Rhinotracheitis (IBR virus could be isolated from the diseased animals. It is suggested that the syndrome resembling BVD/MD complex, may have been caused by an yet unidentified virus.

Acute genital ulcers, also known as acute vulvar ulcers, ulcus vulvae acutum or Lipschütz ulcers, refer to an ulceration of the vulva or lower vagina of non-venereal origin that usually presents in young women, predominantly virgins. Although its incidence is unknown, it seems a rare entity, with few cases reported in the literature. Their aetiology and pathogenesis are still unknown. The disease is characterised by an acute onset of flu-like symptoms with single or multiple painful ulcers on the vulva. Diagnosis is mainly clinical, after exclusion of other causes of vulvar ulcers. The treatment is mainly symptomatic, with spontaneous resolution in 2 weeks and without recurrences in most cases. We present a case report of a 13-year-old girl with two episodes of acute ulcers that fit the clinical criteria for Lipschütz ulcers.

AIM: To establish the efficacy and safety of a 7-d therapeutic regimen using omeprazole, bismuth subcitrate, furazolidone and amoxicillin in patients with peptic ulcer disease who had been previously treated with other therapeutic regimens without success.METHODS: Open cohort study which included patients with peptic ulcer who had previously been treated unsuccessfully with one or more eradication regimens. The therapeutic regimen consisted of 20 mg omeprazole, 240 mg colloidal bismuth subcitrate, 1000 mg amoxicillin, and 200 mg furazolidone, taken twice a day for 7 d. Patients were considered as eradicated when samples taken from the gastric antrum and corpus 12 wk after the end of treatment were negative for Helicobacter pylori (H pylori) (rapidurease test and histology). Safety was determined by the presence of adverse effects. RESULTS: Fifty-one patients were enrolled. The eradication rate was 68.8% (31145). Adverse effects were reported by 31.4% of the patients, and these were usually considered to be slight or moderate in the majority of the cases. Three patients had to withdraw from the treatment due to the presence of severe adverse effects. CONCLUSION: The association of bismuth, furazolidone, amoxicillin and a proton-pump inhibitor is a valuable alternative for patients who failed to respond to other eradication regimens. It is an effective, cheap and safe option for salvage therapy of positive patients.

AIM: To assess the frequency of herpes simplex virus type Ⅰ in upper gastrointestinal tract ulcers and normal mucosa with the modern and better assays and also with a larger number of well characterized patients and controls and its relationship to Helicobacter pylori(H pylori).METHODS: Biopsy specimens from 90 patients (34 with gastric ulcer of the prepyloric area and 56 with duodenal ulcer) were evaluated. Biopsies from 50 patients with endoscopically healthy mucosa were considered as the control group. The method used to identify herpes simplex virus-1 (HSV-1) was polymerase chain reaction.H pylori was detected by the CLO-test and by histological method.RESULTS: Herpes simplex virus-1 was detected in 28 of 90 patients with peptic ulcer (31%) [11 of 34 patients with gastric ulcer (32.4%) and 17 of 56 with duodenal ulcer (30.4%)] exclusively close to the ulcerous lesion.All control group samples were negative for HSV-1.The likelihood of H pylori negativity among peptic ulcer patients was significantly higher in HSV-1 positive cases than in HSV-1 negative cases (P = 0.009). Gastric ulcer patients with HSV-1 positivity were Strongly associated with an increased possibility of Helicobacter pylori negativity compared to duodenal ulcer patients (P= 0.010).CONCLUSION: HSV-1 is frequent in upper gastrointestinal tract ulcers but not in normal gastric and duodenal mucosa. There is an inverse association between HSV-1 and H pylori infection.

Mycobacterium ulcerans is an environmental bacterium which causes chronic skin ulcers. Despite significant epidemiological evidence to suggest that water is the source of infection, the organism has never been identified in the environment. Environmental water samples were collected from a small town in which an outbreak of 29 cases had occurred in a 3-year period. These were examined by mycobacterial culture and PCR amplification. Similar to previous studies, M. ulcerans was not cultured from the water samples. However, five samples were positive for M. ulcerans by PCR. These samples were collected from a swamp and a golf course irrigation system within the outbreak area. This is the first time that M. ulcerans has been demonstrated to be present in the environment and supports the postulated epidemiology of disease due to this organism.
Full Text Available Mycobacterium ulcerans infection, known as Buruli ulcer, is a disease of the skin and subcutaneous tissues which is an important but neglected tropical disease with its major impact in rural parts of West and Central Africa where facilities for diagnosis and management are poorly developed. We evaluated fluorescent thin layer chromatography (f-TLC for detection of mycolactone in the laboratory using samples from patients with Buruli ulcer and patients with similar lesions that gave a negative result on PCR for the IS2404 repeat sequence of M. ulcerans.Mycolactone and DNA extracts from fine needle aspiration (FNA, swabs and biopsy specimen were used to determine the sensitivity and specificity of f-TLC when compared with PCR for the IS2404. For 71 IS2404 PCR positive and 28 PCR negative samples the sensitivity was 73.2% and specificity of 85.7% for f-TLC. The sensitivity was similar for swabs (73%, FNAs (75% and biopsies (70%.We have shown that mycolactone can be detected from M. ulcerans infected skin tissue by f-TLC technique. The technique is simple, easy to perform and read with minimal costs. In this study it was undertaken by a member of the group from each endemic country. It is a potentially implementable tool at the district level after evaluation in larger field studies.

AIM:To investigate age,sex,histopathology and Helicobacter pylori (H.pylori) status,as risk factors for gastroduodenal disease outcome in Brazilian dyspeptic patients.METHODS:From all 1466 consecutive dyspeptic patients submitted to upper gastroscopy at Hospital das Clinicas of Marilia,antral biopsy specimens were obtained and subjected to histopathology and H.pylori diagnosis.All patients presenting chronic gastritis (CG)and peptic ulcer (PU) disease localized in the stomach,gastric ulcer (GU) and/or duodenal ulcer (DU) were included in the study.Gastric biopsies (n =668) positive for H.pylori by rapid urease test were investigated for vacuolating cytotoxin A (vacA) medium (m) region mosaicism by polymerase chain reaction.Logistic regression analysis was performed to verify the association of age,sex,histopathologic alterations,H.pylori diagnosis and vacA m region mosaicism with the incidence of DU,GU and CG in patients.RESULTS:Of 1466 patients submitted to endoscopy,1060 (72.3％) presented CG [male/female =506/554;mean age (year) ± SD =51.2 ± 17.81],88 (6.0％)presented DU [male/female =54/34; mean age (year)± SD =51.4 ± 17.14],and 75 (5.1％) presented GU[male/female =54/21; mean age (year) ± SD =51.3± 17.12] and were included in the comparative analysis.Sex and age showed no detectable effect on CG incidence (overall x2 =2.1,P =0.3423).Sex [Odds ratios (OR) =1.8631,P =0.0058] but not age (OR =0.9929,P =0.2699) was associated with DU and both parameters had a highly significant effect on GU (overall x2 =30.5,P ＜ 0.0001).The histopathological results showed a significant contribution of ageing for both atrophy (OR =1.0297,P ＜ 0.0001) and intestinal metaplasia (OR =1.0520,P ＜ 0.0001).Presence of H.pylori was significantly associated with decreasing age (OR =0.9827,P ＜ 0.0001) and with the incidence of DU (OR =3.6077,P ＜ 0.0001).The prevalence of ml in DU was statistically significant (OR =2.3563,P =0.0018) but not in CG (OR =2.678,P =0.0863) and
Full Text Available PURPOSE: One hundred and ten Helicobacter pylori isolates from peptic ulcer disease patients and matched controls were analysed for any possible relationship between the presence of cryptic plasmids and their antibiotic sensitivity pattern. METHODS: Antral biopsies of patients with gastric and duodenal ulcer, gastric cancer, non ulcer dyspepsia and matched controls were cultured for H.pylori. Antibiotic susceptibility and MIC analysis of the clinical isolates was done by E-test. Plasmid profiles of the isolates were analysed using mini ultra prep plasmid kit. RESULTS: Out of the 110 isolates tested, 89.1% isolates were resistant to metronidazole, 10.9 % were resistant to clarithromycin and 0.9% were resistant to multiple drugs. Isolates harbouring plasmids were seen in all the groups and constituted 5.4% of total isolates. CONCLUSIONS: The presence of plasmids in the clinical isolates of H.pylori did not have any correlation with their antibiotic resistance pattern.

End-stage renal disease (ESRD) patients exhibit an increased incidence of peptic ulcer disease. Helicobacter pylori plays a central role in the development of peptic ulcers. The effect of early H pylori eradication on the recurrence of complicated peptic ulcer disease in ESRD patients remains unclear. The aim of the present study was to explore whether early H pylori eradication therapy in ESRD patients can reduce the risk of recurrent complicated peptic ulcers.We conducted a population-based cohort study and recruited patients with ESRD who had developed peptic ulcers. We categorized patients into early (time lag ≦120 days after peptic ulcer diagnosis) and late H pylori eradication therapy groups. The Cox proportional hazards model was used. The endpoint was based on hospitalization for complicated recurrent peptic ulcers.The early and late H pylori eradication therapy groups consisted of 2406 and 1356 ESRD patients, respectively, in a time lag of 120 days. After adjusting for possible confounders, the early eradication group exhibited a lower rate of complicated recurrent peptic ulcer disease (hazard ratio [HR] = 0.76, 95% confidence interval [CI] = 0.64-0.91, P = 0.003) in a time lag of ≦120 days, but a similar rate of complicated recurrent peptic ulcer disease in time lags of ≦1 year (HR = 0.97, 95% CI 0.79-1.19, P = 0.758) and 2 years (HR = 1.11, 95% CI 0.86-1.44, P = 0.433) compared with the late eradication group.We recommend administering H pylori eradication within 120 days after peptic ulcer diagnosis to H pylori infected ESRD patients who have developed peptic ulcers.

Despite significant improvements in our understanding of Crohn’s disease(CD) and ulcerative colitis(UC) in recent years, questions remain regarding the best approaches to assessment and management of these chronic diseases during periods of both relapse and remission. Various serologic biomarkers have been used in the evaluation of patients with both suspected and documented inflammatory bowel disease(IBD), and while each has potential utility in the assessment of patients with IBD, potential limitation remain with each method of assessment. Given these potential shortcomings, there has been increased interest in other means of evaluation of patients with IBD, including an expanding interest in the role of gene expression profiling. Among patients with IBD, gene expression profiles obtained from whole blood have been used to differentiate active from inactive CD, as well as to differentiate between CD, UC, and non-inflammatory diarrheal conditions. There are many opportunities for a non-invasive, blood based test to aid in the assessment of patients with IBD, particularly when considering more invasive means of evaluation including endoscopy with biopsy. Furthermore, as the emphasis on personalized medicine continues to increase, the potential ability of gene expression analysis to predict patient response to individual therapies offers great promise. While whole blood gene expression analysis may not completely replace more traditional means of evaluating patients with suspected or known IBD, it does offer significant potential to expand our knowledge of the underlying genes involved in the development of these diseases.

Full Text Available Refractory or intractable ulcer is defined as an ulcer that fails to heal completely after eight to twelve weeks, despite appropriate treatment with a modern antiulcer therapy in a compliant patient. Refractory ulcer should be suspected in individuals diagnosed to have peptic ulcer if their symptoms persist longer than usual: occurrence of complications or simply their ulcers fail to heal, since up to 25% of such patients remain asymptomatic. Conditions associated with refractory ulcer include noncompliance, continuous consumption of nonsteroidal anti-inflam-matory drugs, acid hypersecretion, smoking. male gender and other factors with questionable role like advanced age, large ulcer size, prolonged duration of symptoms and the presence of complication like bleeding. Nonpeptic ulcers like tuberculosis, malignancy, Crohn′s disease and primary intestinal lymphoma should always be considered in the differential diagnosis. Colonization with H. pylori which is well-known as a cause of frequent recurrences, has not been linked with refractoriness. Patients with refractory ulcers must undergo thorough re-evaluation including repeated endoscopies, obtaining biopsies for microbiology and histology and determination of serum-gastrin level. Once diseases with identifiable etiologies have been ruled out, aggressive medical management with single or multiple antiulcer drugs should be instituted. Such treatments will virtually heal all refractory ulcers. Surgery should be reserved for patients whose ulcers fail to respond to optimal medical therapy or those who develop com-plications necessitating surgical intervention.

The incidence of inflammatory bowel disease (IBD) and associated oxidative stress is increasing. The antioxidant mineral selenium (Se) was measured in serum samples from 106 IBD patients (53 with ulcerative colitis (UC) and 53 with Crohn’s disease (CD)) and from 30 healthy controls. Serum Se concentrations were significantly lower in UC and CD patients than in healthy controls (p < 0.001) and significantly lower in CD patients than in UC patients (p = 0.006). Se concentrations in patients ...
Full Text Available BACKGROUND & AIM: The relationship between Helicobacter pylori infection and peptic ulcer disease in cirrhosis remains controversial.

Full Text Available OBJECTIVES: To determine the etiology and factors associated with genital ulcer disease (GUD among patients presenting to a sexually transmitted infections clinic in Manaus, Brazil; and to compare a multiplex polymerase chain reaction (M-PCR assay for the diagnosis of GUD with standard methods. METHODS: Ulcer swabs were collected and used for Tzanck test and processed in an M-PCR to detect herpes simplex virus (HSV-1/2, Treponema pallidum (T. pallidum, and Haemophilus ducreyi (H. ducreyi. Sera were tested for HIV and syphilis antibodies. Multivariable analysis was used to measure the association between clinical aspects and GUD. M-PCR results were compared with syphilis serology and Tzanck tests. RESULTS: Overall, 434 GUD samples were evaluated, 84.8% from men. DNA from HSV-2 was detected in 55.3% of GUD samples, T. pallidum in 8.3%, HSV-1 in 3.2%, and 32.5% of GUD specimens were negative for the DNA of all three pathogens. No cases of H. ducreyi were identified. HIV serology among GUD patients was 3.2%. Treponemal antibodies and Tzanck test positivity for genital herpes was detected in 25 (5.8% and in 125 (30.3% of GUD patients, respectively. In multivariable analysis genital herpes etiology by M-PCR was associated with the vesicular, multiple and recurrent lesions whereas T. pallidum with non-vesicular, non-recurrent lesions. Compared to M-PCR, syphilis serology was 27.8% sensitive and 96.2% specific whereas Tzanck test was 43.8% sensitive and 88.9% specific. CONCLUSIONS: The predominance of genital herpes etiology suggests a revision of existing national syndromic treatment guidelines in Brazil to include antiherpetic treatment for all GUD patients. The use of M-PCR can significantly improve the diagnosis of GUD and provide a greater sensitivity than standard diagnostics.

The therapeutic agent colloidal bismuth subcitrate (CBS) selectively binds to peptic ulcers. The authors have developed a method for labeling this agent with Tc-99m. Chromatographic quality control studies of the agent on silica gel coated strips (ITLC-SG) showed that more than 97% of Tc-99m was bound to CBS. During in-vitro stability testing, the radio-label was stable for a minimum of 6 hours. The chromatographic findings are in agreement with the in-vivo distribution of the agent which showed no significant radioactivity in thyroid, kidneys, liver, or bladder. The resulting Tc-99m-CBS solution is administered orally in drinking water. Preliminary animal studies have been conducted on 5 adult 3 kg New Zealand rabbits sedated with 50 mg Ketamine I.M. The rabbits were intubated with I.V. tubing advanced to the stomach. They were given a gastric erosive suspension of 600-1000 mg/kg of pulverized ASA in 10 cc tap water. Four hours later they were given 3-4 mCi of the radiotracer in a 5 cc volume of water. Serial in-vivo images were obtained for 2 hours which included thyroid, abdomen, and urinary bladder. Next the stomachs were excised, opened along the greater curvature, imaged, vigorously washed and reimaged. All 5 rabbits showed avid localized binding of radiotracer which remained fixed even with vigorous washing. Areas of normal appearing mucosa were relatively devoid of radiotracer. This new compound may have significant clinical usefulness in the detection of peptic ulcer disease. In addition, such a non-invasive technique, carrying none of the risks or discomfort of endoscopy could also find application in the evaluation of the response to therapy.

AIM: It is controversial whether patients with non-ulcer dyspepsia (NUD) respond differently to Helicobacter pylori (H pylori) eradication treatment than those with peptic ulcer disease (PUD). To review the evidence for any difference in H pylori eradication rates between PUD and NUD patients. METHODS: A literature search for full articles and meeting abstracts to July 2004 was conducted. We included studies evaluating the efficacy of a proton pump inhibitor (P) or ranitidine bismuth citrate (RBC) plus two antibiotics of clarithromycin (C), amoxicillin (A), metronidazole (M), or P-based quadruple therapies for eradicating theinfection.RESULTS: Twenty-two studies met the criteria. No significant difference in eradication rates was found between PUD and NUD patients when treated with 7-d RBCCA, 10-d PCA or P-based quadruple therapies. When the 7-d PCA was used, the pooled H pylori eradication rate was 82.1% (431/525) and 72.6% (448/617) for PUD and NUD patients, respectively, yielding a RR of 1.15(95%CI 1.01-1.29). However, the statistically significant difference was seen only in meeting abstracts, but not in full publications.CONCLUSION: There is no convincing evidence to suggest that NUD patients respond to H pylori eradication treatments differently from those with PUD, although a trend exists with the 7-d PCA therapy.

Its eradication has been shown to reduce rates of H pylori-related ulcers as well as other complications such as gastric cancer.
Full Text Available Primary adult hypertrophic stenosis is uncommon with an uncertain etiopathogenesis and associated gastric outlet obstruction mimics gastric carcinoma. We present a case of AHPS as sequel of peptic ulcer disease in a 72 year old male. With the advent of proton pump inhibitors as a mainstay of medical therapy, complication into gastric outlet obstruction is a rare disease today. Upper GI endoscopy revealed a distended stomach, residual food and a hyperemic bulky pylorus not accommodating the endoscope. Barium meal follow-through revealed a dilated stomach and minimal barium passing through the pylorus. Histological analysis revealed mild dysplasia at the focus with dense inflammatory infiltrates composed of lymphocytes and eosinophils in the lamina propria. No evidence of malignancy was noted, favouring chronic gastritis. The condition mimics other forms of proliferative disorders like carcinoma, gastrointestinal stromal tumors. We present the clinical findings, imaging analysis and discuss etiopathogenesis and management. [Int J Res Med Sci 2016; 4(5.000: 1730-1732
Full Text Available Objectives. To assess the relationship between infections and the risk of pediatric-onset inflammatory bowel disease (IBD. Methods. We conducted a nested case-control study of 501 incident cases aged ≤17 years and 9,442 controls who were members of Kaiser Permanente Northern California for at least one consecutive year between 1996 and 2006. IBD was confirmed and the incidence date was adjudicated by pediatric gastroenterologists. Hospitalized infections were identified from the principal diagnosis code of electronic inpatient records. Medications to treat infections were identified during the hospitalization. Conditional logistic regression was used to assess the associations between hospitalized infections, medications, and Crohn’s disease and ulcerative colitis. Results. In the year prior to diagnosis, both hospitalized infection of any system (OR 6.3; 95% CI 1.6–23.9 and hospitalized intestinal infection (OR 19.4; 95% CI 2.6–143.2 were associated with CD. Hospitalized infections of any system were inversely associated with UC after excluding the year prior to diagnosis (OR 0.4; 95% CI 0.2–0.9. No UC case had a hospitalized gastrointestinal infection prior to diagnosis. Conclusion. Infections appear to play opposite roles prior to the diagnosis of CD and UC. Infections may be associated with an increased risk of CD and a decreased risk of UC.

Peptic ulcer has frequently been associated with liver cirrhosis. The death rate for peptic ulcer in cirrhotics has been reported to be five times higher than in general population. The underlying mechanisms are poorly understood. Different factors have been claimed to be involved, such as alterations in serum gastrin level, gastric acid secretions, mucosal blood flow and decreased prostaglandin production in gastric mucosa. Moreover, Helicobacter pylori infection, when accurately assessed, is detectable in most peptic ulcer cirrhotics. Since the H. pylori infection strongly correlates with peptic ulcer in general population, it is necessary to clarify the role of H. pylori in the pathogenesis of peptic ulcer in cirrhosis before eradication can be proposed as a preventive measure.
OBJECTIVE: To optimize total bacterial 16S rRNA quantification in microdissected colonic crypts in healthy controls and patients with ulcerative colitis (UC) and to characterize the findings with disease activity. BACKGROUND: Microscopic and molecular techniques have recently converged to allow bacterial enumeration in remote anatomic locations [eg, crypt-associated mucous gel (CAMG)]. The aims of this study were to combine laser capture microdissection (LCM) and 16S rRNA-based quantitative polymerase chain reaction (qPCR) to determine total bacterial copy number in CAMG both in health and in UC and to characterize the findings with disease activity. METHODS: LCM was used to microdissect CAMG from colonic mucosal biopsies from controls (n = 20) and patients with acute (n = 10) or subacute (n = 10) UC. Pan-bacterial 16S rRNA copy number per millimeter square in samples from 6 locations across the large bowel was obtained by qPCR using Desulfovibrio desulfuricans as a reference strain. Copy numbers were correlated with the UC disease activity index (UCDAI) and the simple clinical colitis activity index (SCCAI). RESULTS: Bacterial colonization of CAMG was detectable in all groups. Copy numbers were significantly reduced in acute UC. In subacute colitis, there was a positive correlation between copy number and UCDAI and SCCAI in the ascending, transverse and sigmoid colon. CONCLUSIONS: This study describes a sensitive method of quantitatively assessing bacterial colonization of the colonic CAMG. A positive correlation was found between CAMG bacterial load and subacute disease activity in UC, whereas detectable bacterial load was reduced in acute UC.

AIM:To investigate possibility and clinical application of fecal calprotectin in determining disease activity of ulcerative colitis (UC).METHODS: The enzyme-linked immunosorbent assay(ELISA) was used to measure the concentrations of calprotectin in feces obtained from 66 patients with UC and 20 controls. C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), acid glycoprotein (AGP) were also measured and were compared with calprotectin in determining disease activity of UC. The disease activity of UC was also determined by the Sutherland criteria.RESULTS: The fecal calprotectin concentration in the patients with active UC was significantly higher than that in the inactive UC and in the controls (402.16±48.0 μg/g vs 35.93±3.39 μg/g, 11.5±3.42 μg/g, P < 0.01). The fecal calprotectin concentration in the inactive UC group was significantly higher than that in the control group (P < 0.05). A significant difference was also found in the patients with active UC of mild, moderate and severe degrees. The area under the curve of the receiver operating characteristics (AUCROC) was 0.975, 0.740, 0.692 and 0.737 for fecal calprotectin, CRP, ESR and AGP,respectively. There was a strong correlation between the fecal calprotectin concentration and the endoscopic gradings for UC (r = 0.866, P < 0.001).CONCLUSION: Calprotectin in the patient's feces can reflect the disease activity of UC and can be used as a rational fecal marker for intestinal inflammation in clinical practice. This kind of marker is relatively precise, simple and noninvasive when compared with other commonly-used markers such as CRP, ESR and AGR.

Stroke is a common cause of death worldwide, but about 30% of ischemic stroke (IS) patients have no identifiable contributing risk factors. Because peptic ulcer disease (PUD) and vascular events share some common risk factors, we conducted a population-based study to evaluate the association between PUD and IS.We followed up a representative sample of 1 million residents of Taiwan using the National Health Insurance Research Database from 1997 to 2011. We defined patients who received medications for PUD and had related diagnosis codes as the PUD group, and a reference group matched by age and sex was sampled from those who did not have PUD. We also collected data on medical history and monthly income. The events of IS occurred after enrollment were compared between the 2 groups. The data were analyzed using Cox proportional hazard models at the 2-tailed significant level of 0.05.The PUD group had higher income and prevalence of hypertension, diabetes mellitus (DM), heart disease, and hyperlipidemia. They also had a higher risk of developing IS with an adjusted hazard ratio of 1.31 (95% confidence interval: 1.20-1.41). Other independent risk factors included male sex, older age, lower income, and co-morbidity of hypertension, diabetes mellitus (DM), and heart disease.PUD is a risk factor for IS, independent of conventional risk factors such as male sex, older age, lower income, and co-morbidity of hypertension, DM, and heart disease. Prevention strategies taking into account PUD should be developed and evaluated.
Full Text Available BACKGROUND: In developing countries, the proportion with STDs who present with genital ulcers is high compared to developed nations. AIM: 1. To study reaction of the cases toward their disease. 2. To study communication of cases with their partners. 3. To study treatment of symptoms and starting treatment, selfmedication & completion of treatment. 4. To study approach of health care providers. STUDY SETTINGS: Present study was carried out in Department of skin and VD, Medical College and SSG Hospital Baroda between June 2001 to Feb. 2003. MATERIAL AND METHODS: A cross sectional study was conducted. Sexually active male or female having genital ulcer with history of exposure in patient or partner. Total 216 cases were included in the study. Detailed history was taken and was recorded. An attempt was made to study health care seeking behavior in 60 cases. These cases were questioned about their reaction towards the disease treatment seeking including completion of treatment and time gap between appearance of symptoms and treatment taken were asked. They were also asked about the approach of the health care providers from whom they took treatment before coming to our clinic. RESULTS: It was observed that 57% of the cases among males were frightened after having GUD. They were likely to come to STD clinics at the earliest for treatment. Spousal communication was only 45% in male cases. Only 1/3rd cases came directly to STD clinic and the other visited other practitioners. Among these, only 60% took treatment from MBBS doctors or STD specialist. Rest of them went to unqualified health. Awareness about protective value of condom, as for as STI prevention is concerned, was 70% but consistent use was seen only in 2% cases. Twenty one percent cases did not know how to use condom, and 7% did not know about condoms at all. As many as 89% cases didn’t feel it necessary to use condoms during sexual relations with wife. CONCLUSION: Creating awareness

Genetic diversification allows Helicobacter pylori to persist during chronic colonization/infection. We investigated the intra-host variation of several markers that suggested microevolution in patients with chonic gastritis (CG) and peptic ulcer disease (PUD). One-hundred twenty-six isolates recovered from 14 patients with CG and 13 patients with PUD were analysed. cag pathogenicity island (cagPAI), oipA, vacA, bab gene status and the presence of jhp0926, jhp0945, jhp0947, jhp0949 and jhp0940 genes from the genomic Plasticity Zone (PZ) were taken into accout to investigate intra-host variation. lspA-glmM-RFLP was performed to identify mixed infections. Only one patient was colonised/infected by two ancestrally unrelated strains. Among the 126 isolates, a significant association among cagPAI genotypes, oipA status and vacA alleles was indicated. Complete cagPAI, oipA "on", and vacA s1-m1 variants were significantly found in patients with PUD, without intra-host variations. Isolates from 7/14 patients with CG lacked babA in all chromosomal loci. In contrast, isolates from all or several biopsies of PUD patients carried babA, but in one patient only, the isolates showed positive Lewis b (Leb) binding assay. Considering cagPAI, vacA, oipA, bab genotypes, intra-host variation was also significantly higher in patients with CG. Conversely, a similarly high intra-host variation in almost PZ genes was observed in isolates from patients with CG and PUD. In conclusion, the lowest intra-host variation in cagPAI, oipA, vacA, and bab genes found in patients with PUD suggests the selection of a particular variant along the bacteria-host environment interplay during ulceration development. However, the predominance of this variant may be a refletion of the multifactorial etiology of the disease rather than the cause, as it was also found in patients with CG. The intra-host variation in PZ genes may predict that this genomic region and the other markers of microevolution studied

Purpose A duodenal bypass after a Roux-en-Y gastric bypass operation for obesity can ameliorate the development of diabetes mellitus (DM). We attempted to determine the subsequent risk of developing DM after subtotal gastrectomy with Billroth II anastomosis (SGBIIA) for peptic ulcer disease (PUD). Methods We identified 662 patients undergoing SGBIIA for PUD between 2000 and 2011 from the Longitudinal Health Insurance Database as the study cohort, and we randomly selected 2647 controls from the peptic ulcer population not undergoing SGBIIA and were frequency-matched by age, sex, and index year for the control cohort. All patient cases in both cohorts were followed until the end of 2011 to measure the incidence of DM. We analyzed DM risk by using a Cox proportional hazards regression model. Results The patients who underwent SGBIIA demonstrated a lower cumulative incidence of DM compared with the control cohort (log-rank test, P < .001 and 6.73 vs 12.6 per 1000 person-y). The difference in the DM risk between patients with and without SGBIIA increased gradually with the follow-up duration. Age and sex did not affect the subsequent risk of developing DM, according to the multivariable Cox regression model. Nevertheless, the SGBIIA cohort exhibited a lower DM risk after we adjusted for the comorbidities of hypertension, hyperlipidemia, and coronary artery disease (adjusted hazard ratio (aHR): 0.56, 95% confidence interval (CI): 0.40–0.78). The incidence rate ratio (IRR) of DM in the SGBIIA cohort was lower than that in the control cohort for all age groups (age ≤ 49 y, IRR: 0.40, 95% CI: 0.16–0.99; age 50–64 y, IRR: 0.54, 95% CI: 0.31–0.96; age ≧ 65 y, IRR: 0.57, 95% CI: 0.36–0.91). Moreover, the IRR of DM was significantly lower in the SGBIIA cohort with comorbidities (IRR: 0.50, 95% CI: 0.31–0.78) compared with those without a comorbidity (IRR: 0.65, 95% CI: 0.40–1.04). Conclusion The findings of this population-based cohort study revealed that

Clinical decision-making for the treatment of patients with diseased carotid artery is mainly based on the severity of the stenosis. However, stenosis severity alone is not a sensitive indicator, and other local factors for the assessment of stroke risk are required. Flow disturbance is of particular interest due to its proven association with increased thromboembolic activities. The objective of this study was to investigate the level of turbulence intensity (TI) with regards to certain geometrical features of the plaque - namely stenosis severity, eccentricity, and ulceration. A family of eight carotid-artery bifurcation models was examined using particle image velocimetry. Results showed a marked difference in turbulence intensity among these models; increasing degree of stenosis severity resulted in increased turbulence intensity, going from 0.12 m/s for mild stenosis to 0.37 m/s for severe stenosis (with concentric geometry). Moreover, independent of stenosis severity, eccentricity led to further elevations in turbulence intensity, increasing TI by 0.05-0.10 m/s over the counterpart concentric plaque. The presence of ulceration (in a 50% eccentric plaque) produced a larger portion of moderate turbulence intensity (~0.10 m/s) compared to the non-ulcerated model, more proximal to the bifurcation apex in the post-stenotic recirculation zone. The effect of plaque eccentricity and ulceration in enhancing the downstream turbulence has potential clinical implications for a more sensitive assessment of stroke risk beyond stenosis severity alone.
Full Text Available Background: Peptic ulcer disease can lead to serious complications including massive hemorrhage or bowel perforation. The modern treatment of peptic ulcer disease has transitioned from the control of gastric acid secretion to include antibiotic therapy in light of the identification of Helicobacter pylori as a causative infectious organism. We sought to determine trends related to this discovery by using a national database. Materials and Methods: Patient discharges with peptic ulcer disease and associated sequelae were queried from the Nationwide Inpatient Sample, 1993 to 2007, under the auspices of a data user agreement. To account for the Nationwide Inpatient Sample weighting schema, design-adjusted analyses were used. Standard error was calculated using SUDAAN software (Research Triangle International, NC, USA. Results: Decreases in the incidences of gastrointestinal perforation, gastrointestinal hemorrhage, and surgical procedures most specific to peptic ulcer disease were statistically significant over the study period [range of P value (two tailed = 0.000 - 0.00353; significant at P < 0.001 to < 0.01]. The incidence of H. pylori rose dramatically, peaking at an estimated 97,823 cases in 1998 [SE = 3155; 95% CI = 6,184]. Since that time it has decreased and then stabilized. Conclusions: The identification of H. pylori as the causative agent in the majority of peptic ulcer disease has revolutionized the understanding and management of the disease. Medical conditions and surgical procedures associated with end-stage peptic ulcer disease have significantly decreased according to analysis of selected index categories. Resident physician education objectives may need to be modified in light of these trends. Review Criteria: We reviewed patients with peptic ulcer disease. The database used was the Nationwide Inpatient Sample, 1993 to 2007. Message for the Clinic: Medical therapy has resulted in decreased morbidity from H. pylori infection as it

Background Polyamines are important in cell growth and wound repair, but have also been implicated in inflammation-induced carcinogenesis. Polyamine metabolism includes back-conversion of spermine to spermidine by the enzyme spermine oxidase (SMO), which produces hydrogen peroxide that causes oxidative stress. In ulcerative colitis (UC), levels of spermine are decreased compared to spermidine. Therefore, we sought to determine if SMO is involved in UC. Methods Colon biopsies and clinical information from subjects undergoing colonoscopy for evaluation of UC or colorectal cancer screening were utilized from 16 normal controls and 53 UC cases. Histopathologic disease severity was graded and the Mayo Disease Activity Index (DAI) and endoscopy subscore assessed. SMO mRNA expression was measured in frozen biopsies by Taq-Man-based real-time polymerase chain reaction (PCR). Formalin-fixed tissues were used for SMO immunohistochemistry. Results There was a 3.1-fold upregulation of SMO mRNA levels in UC patients compared to controls (P = 0.044), and a 3.7-fold increase in involved left colon versus paired uninvolved right colon (P < 0.001). With worsening histologic injury in UC there was a progressive increase in SMO staining of mononuclear inflammatory cells. There was a similar increase in SMO staining with worsening endoscopic disease severity and strong correlation with the DAI (r = 0.653, P < 0.001). Inflammatory cell SMO staining was increased in involved left colon versus uninvolved right colon. Conclusions SMO expression is upregulated in UC tissues, deriving from increased levels in mononuclear inflammatory cells. Dysregulated polyamine homeostasis may contribute to chronic UC by altering immune responses and increasing oxidative stress. PMID:20127992

Objective To establish a multiplex polymerase chain reaction (M-PCR) assay for simultaneous detection of pathogens causing genital ulcer disease (GUD).Methods Based on the gene-specific region of the following pathogens: Chlamydia trachomatis ompl/ompb, herpes simplex virus (HSV) DNA polymerase, Treponema pallidum tpp47, Haemophilus ducreyi 16s rRNA, four sets of primers were designed and an M-PCR assay was developed to detect four pathogens in one test. The assay was evaluated with diagnostic result of golden standard for each pathogen.Results Of the 51 clinical samples, M-PCR showed slightly higher positive rate (47.1%) of HSV than cell culture (23.6%).Meanwhile, the positive rate of T. p allidum detected by M-PCR and dark-field microscopy was 19.6% ( 10/51) and 15.7% (8/51),respectively. Only one sample was positive for H. ducreyiand no sample was positive for C. trachomatis detected by both M-PCR assay and culture.Conclusion This primary study indicated that M-PCR assay can simultaneously and rapidly detect the four etiologic pathogens causing GUD.

The most common causes of peptic ulcer disease (PUD) are Helicobacter pylori infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs). The test-and-treat strategy for detecting H. pylori is appropriate in situations where the risk of gastric cancer is low based on age younger than 55 years and the absence of alarm symptoms. Most other patients should undergo upper endoscopy to rule out malignancy and other serious causes of dyspepsia. Urea breath tests and stool antigen tests are most accurate for identifying H. pylori infection and can be used to confirm cure; serologic tests are a convenient but less accurate alternative and cannot be used to confirm cure. Treatment choices include standard triple therapy, sequential therapy, quadruple therapy, and levofloxacin-based triple therapy. Standard triple therapy is only recommended when resistance to clarithromycin is low. Chronic use of NSAIDs in patients with H. pylori infection increases the risk of PUD. Recommended therapies for preventing PUD in these patients include misoprostol and proton pump inhibitors. Complications of PUD include bleeding, perforation, gastric outlet obstruction, and gastric cancer. Older persons are at higher risk of PUD because of high-risk medication use, including antiplatelet drugs, warfarin, selective serotonin reuptake inhibitors, and bisphosphonates.

The risk of peptic ulcer disease (PUD) among patients with depression has raised concern. This study determined the association between depression and the subsequent development of PUD using claims data.Patients newly diagnosed with depression in 2000 to 2010 were identified as depression cohort from the Taiwan National Health Insurance Research Database. The comparison cohort was randomly selected from subjects without depression, frequency matched by age and gender and diagnosis date, with a size 2-fold of the size of the depression cohort. The incidence of PUD was evaluated for both cohorts by the end of 2011. We calculated the hazard ratios (HRs) and 95% confidence intervals (CIs) of PUD using the Cox proportional hazards regression model.The depression cohort consisted of 23,536 subjects (129,751 person-years), and the comparison cohort consisted of 47,069 subjects (285,592 person-years). The incidence of PUD was 2-fold higher in the depression cohort than in the comparison cohort (33.2 vs 16.8 per 1000 person-years) with an age adjusted HR of 1.97 (95% CI = 1.89-2.06) or a multivariable adjusted HR of 1.35 (95% CI = 1.29-1.42).Depression might increase the risk of developing PUD. Prospective clinical studies of the relationship between depression and PUD are warranted.

Throughout the first half of the twentieth century the research on peptic ulcer disease (PUD) focused on two rivaling hypothesis: the "acidity" and the "bacterial" one. According to the received view, the latter was dismissed during the 1950s only to be revived with Warren's and Marshall's discovery of Helicobacter pylori in the 1980s. In this paper we investigate why the bacterial hypothesis was largely abandoned in the 1950s, and whether there were good epistemic reasons for its dismissal. Of special interest for our research question is Palmer's 1954 large-scale study, which challenged the bacterial hypothesis with serious counter-evidence, and which by many scholars is considered as the shifting point in the research on PUD. However, we show that: (1) The perceived refutatory impact of Palmer's study was disproportionate to its methodological rigor. This undermines its perceived status as a crucial experiment against the bacterial hypothesis. (2) In view of this and other considerations we argue that the bacterial hypothesis was worthy of pursuit in the 1950s.

Results of study of microecological disorders in oral cavity of patients with non-specific ulcerative colitis (NSUC) and Crohn's disease (CD) and control subjects (patients with hypertension). Condition of mucosa was assessed on the basis of morphological data and electrophoretic mobility of cell nuclei, whereas structure of microbiocenosis and metabolic activity of microflora--on the basis of saliva bacterial culture and contents and profile of volatile fat acids in it. Detection rate of negative charge of the cell nuclei (decrease of functional activity of epithelium) was significantly higher in patients with NSUC and CD (66.6%) compared with controls (10%). This fact was directly related with hypercolonization of oral cavity by Gram-negative microflora. Lesions of mucosa which are characteristic of NSUC and CD and determined by pathologic immune mechanisms correlated with quantity of pathogenic microflora (Staphylococcus aureus and Candida). Marked differences of chromatograms' patterns were observed in patients with NSUC and CD indicating the suppression of anaerobic microflora in patients with CD and hypercolonization of oral cavity by anaerobic microflora in majority of patients with NSUC.

OBJECTIVE To determine the microbiological profile of diabetes-related foot infections (DRFIs) and the impact of wound duration, inpatient treatment, and chronic kidney disease (CKD). RESEARCH DESIGN AND METHODS Postdebridement microbiological samples were collected from individuals presenting with DRFIs from 1 January 2005 to 31 December 2007. RESULTS A total of 653 specimens were collected from 379 individuals with 36% identifying only one isolate. Of the total isolates, 77% were gram-positive bacteria (staphylococci 43%, streptococci 13%). Methicillin-resistant Staphylococcus aureus (MRSA) was isolated from 23%; risk factors for MRSA included prolonged wound duration (odds ratio 2.31), inpatient management (2.19), and CKD (OR 1.49). Gram-negative infections were more prevalent with inpatient management (P = 0.002) and prolonged wound duration (P < 0.001). Pseudomonal isolates were more common in chronic wounds (P < 0.001). CONCLUSIONS DRFIs are predominantly due to gram-positive aerobes but are usually polymicrobial and increase in complexity with inpatient care and ulcer duration. In the presence of prolonged duration, inpatient management, or CKD, empiric MRSA antibiotic cover should be considered. PMID:19587371
Full Text Available GIST tumors is very unusual in the young and middle aged and a high index of suspicion is needed for the diagnosis in young patients who present with upper gastrointestinal bleeding. Appropriate imaging such as a Computed tomographic scan (CT scan may identify this tumor which may easily be misdiagnosed as a bleeding Peptic Ulcer Disease in the young. We present a case of a healthy 38 year old man with no alcohol use who presented with epigastric pain and melena and subsequent torrential bleeding uncontrolled during endoscopy necessitating an emergency exploratory laparotomy by the general surgery team. The bleeding intraluminal component of the tumor with gross splenic and pancreatic involvement was identified and surgical management consisted of a wedge resection of the greater curvature of the stomach incorporating the tumor and the spleen with successful dissection of the tumor off the tail of the pancreas. Histology was positive for C-KIT and DOG-1 markers. Postoperative course was uneventful and he is presently on Imatinib Mesylate.
Full Text Available Ulcers of the small bowel are rare, and in most cases are due to infections, inflammatory bowel diseases, malignancies or drugs. When none of these causes is recognized, they are classified as ‘nonspecific’ or idiopathic. Such lesions are uncommon, and in most cases present with occlusion. A case of a middle-aged woman with iron deficiency anemia due to occult bleeding, with negative gastroscopy and colonoscopy is presented. The diagnosis of a small bowel pathology resembling Crohn’s disease was made by small bowel follow through and small intestine contrast ultrasonography. An ileal ulcer was identified at surgery, and after resection the patient experienced a stable recovery from the anemia without ulcer recurrence. Neither histology nor clinical or biochemical features suggested the diagnosis of an inflammatory bowel disease. Other possible causes were unlikely and the lesion was therefore diagnosed as idiopathic. This report also focuses on the need and the modality to investigate the small bowel in iron deficiency anemia patients.
Pattern recognition of the long-term disease course before, during, and after pregnancy can provide us with data about the influence of pregnancy on IBD, and vice versa. Determinants that predict an indolent versus an aggressive disease course are currently being sought. Our intention is to analyze...... the disease course during pregnancy in an EU-IBD inception cohort of 1200 patients diagnosed from 1991 to 1993 and followed up for 10 years. We also attempt to evaluate such factors as smoking and medication and to predict pregnancy course and fertility in IBD as well as in a cross-sectional study of members...

Persistent exacerbation of a peptic ulcer may lead to a complicated peptic ulcer (perforation or/and bleeding). The management of complicated peptic ulcers has shifted from acid-reducing vagotomy, drainage, and gastrectomy to simple local suture or non-operative (endoscopic/angiographic) hemostasis. We were interested in the long-term effects of this trend change. In this study, complicated peptic ulcer patients who received acid-reducing vagotomy were compared with those who received simple suture/hemostasis to determine the risk of ischemic heart disease (IHD).This retrospective cohort study analyzed 335,680 peptic ulcer patients recorded from 2000 to 2006 versus 335,680 age-, sex-, comorbidity-, and index-year matched comparisons. Patients with Helicobacter pylori (HP) infection were excluded. In order to identify the effect of vagus nerve severance, patients who received gastrectomy or antrectomy were also excluded. The incidence of IHD in both cohorts, and in the complicated peptic ulcer patients who received acid-reducing vagotomy versus those who received simple suture or hemostasis was evaluated.The overall incidence of IHD was higher in patients with peptic ulcer than those without peptic ulcer (17.00 vs 12.06 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.46 based on multivariable Cox proportional hazards regression analysis controlling for age, sex, Charlson's comorbidity index, and death (competing risk). While comparing peptic ulcer patients with acid-reducing vagotomy to those with simple suture/hemostasis or those without surgical treatment, the aHR (0.58) was the lowest in the acid-reducing vagotomy group.Patients with peptic ulcer have an elevated risk of IHD. However, complicated peptic ulcer patients who received acid-reducing vagotomy were associated with reduced risk of developing IHD.
development and subsequent rupturing of vesicles at the coronary band and in the oral cavity. Vesicles and ulcerations can also occur on the mammary gland. Recovery in adult animals usually occurs in 8-15 days. Clinical signs for most serotypes are less dramatic in sheep and goats. Swine can develop very severe coronary band lesions and high mortality in piglets has been observed. One of the challenges of diagnosing FMD is that it may be clinically similar to several other vesicular or ulcerative diseases. FMD is clinically indistinguishable from Vesicular stomatitis, Swine vesicular disease and Vesicular exanthema of swine. It may also resemble Bovine viral diarrhea, Mucosal disease, Infectious bovine rhinotracheitis, Bluetongue, Bovine papular stomatitis, Bovine mammillitis and Rinderpest.

We analysed the CT examinations of 109 patients with 197 involved bowel locations. 81 patients suffered from Crohn`s disease, 28 from ulcerative colitis. Diagnosis was based on the combination of clinical, endoscopic and histopathologic findings. Three radiologists evaluated the CT series concerning the presence of morphologic changes analogous to conventional radiographic findings. In Crohn`s disease, we found irregular outer contours in 26% of cases. The bowel wall was thickened in 82%. In acute phases, the bowel wall was thickened in 100%. Abscess and fistula as complications of inflammatory disease were present in 26 and 14% respectively. In ulcerative colitis, a target sign of the bowel wall was present in 40%, whereas in Crohn`s disease a homogeneous wall density was present in all but two cases. Reduced attenuation due to submucosal fat deposits was found in 16% and mucosal tunneling in 27% of cases with ulcerative colitis. Even if severe mucosal destructions were found, the outer contour of the gut was smooth and regular in 95% of the ulcerative colitis cases. CT can provide additional information on acuity, extent and complications in inflammatory bowel disease. In combination with conventional radiographic findings a three-step classification for Crohn`s disease and ulcerative colitis (early changes, acute and chronic phase) can be proposed. (orig./MG) [Deutsch] Wir untersuchten computertomographisch 109 Patienten mit 197 erkrankten Darmsegmenten. 81 Patienten litten an M. Crohn und 28 an Colitis ulcerosa. Die Diagnose wurde durch Kombination klinischer, endoskopischer, radiologischer und bioptischer Befunde gesichert. Drei Radiologen bewerteten die Computertomographien und verglichen die Ergebnisse mit den konventionell-radiologischen Befunden. Bei den Patienten mit M. Crohn fanden wir in 26% der Faelle eine irregulaere aeussere Darmwand. Eine Darmwandverdickung lag in 82% vor und fand sich regelmaessig in Darmabschnitten mit floriden Veraenderungen

Full Text Available Abstract Background Helicobacter pylori is a Gram negative bacterium that plays a central role in the etiology of chronic gastritis and peptic ulcer diseases. However, not all H. pylori positive cases develop advanced disease. This discriminatory behavior has been attributed to the difference in virulence of the bacteria. Among all virulence factors, cytotoxin released by H. pylori is the most important factor. In this work, we studied variation in H. pylori isolates from Indian dyspeptic patients on the basis of cytotoxin production and associated changes in K+-dependent ATPase (one of its targets enzyme activity in HeLa cells. Methods The patients were retrospectively grouped on the basis of endoscopic and histopathological observation as having gastritis or peptic ulcer. The HeLa cells were incubated with the broth culture filtrates (BCFs of H. pylori isolates from patients of both groups and observed for the cytopathic effects: morphological changes and viability. In addition, the K+-dependent ATPase activity was measured in HeLa cells extracts. Results The cytotoxin production was observed in 3/7 (gastritis and 4/4 (peptic ulcer H. pylori isolates. The BCFs of cytotoxin producing H. pylori strains reduced the ATPase activity of HeLa cells to 40% of that measured with non-cytotoxin producing H. pylori strains (1.33 μmole Pi/mg protein and 3.36 μmole Pi/mg protein, respectively, p Conclusions Our results suggest that the isolation of cytotoxic H. pylori is more common in severe form of acid peptic diseases (peptic ulcer than in gastritis patients from India. Also the cytotoxin released by H. pylori impairs the ion-transporting ATPase and is a measure of cytotoxicity.

Full Text Available BACKGROUND: Co-infection with herpes simplex virus type 2 (HSV-2 has been associated with increased HIV-1 RNA levels and immune activation, two predictors of HIV-1 progression. The impact of HSV-2 on clinical outcomes among HIV-1 infected pregnant women is unclear. METHODS: HIV-1 infected pregnant women in Nairobi were enrolled antenatally and HSV-2 serology was obtained. HIV-1 RNA and CD4 count were serially measured for 12-24 months postpartum. Survival analysis using endpoints of death, opportunistic infection (OI, and CD4<200 cells µL, and linear mixed models estimating rate of change of HIV-1 RNA and CD4, were used to determine associations between HSV-2 serostatus and HIV-1 progression. RESULTS: Among 296 women, 254 (86% were HSV-2-seropositive. Only 30 (10% women had prior or current genital ulcer disease (GUD; median baseline CD4 count was 422 cells µL. Adjusting for baseline CD4, women with GUD were significantly more likely to have incident OIs (adjusted hazard ratio (aHR 2.79, 95% CI: 1.33-5.85, and there was a trend for association between HSV-2-seropositivity and incident OIs (aHR 3.83, 95% CI: 0.93-15.83. Rate of change in CD4 count and HIV-1 RNA did not differ by HSV-2 status or GUD, despite a trend toward higher baseline HIV-1 RNA in HSV-2-seropositive women (4.73 log10 copies/ml vs. 4.47 log10 copies/ml, P = 0.07. CONCLUSIONS: HSV-2 was highly prevalent and pregnant HIV-1 infected women with GUD were significantly more likely to have incident OIs than women without GUD, suggesting that clinically evident HSV-2 is a more important predictor of HIV-1 disease progression than asymptomatic HSV-2.

To investigate osteoporosis risk in patients with peptic ulcer disease (PUD) using a nationwide population-based dataset. This Taiwan National Health Insurance Research Database (NHIRD) analysis included 27,132 patients aged 18 years and older who had been diagnosed with PUD (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 531-534) during 1996 to 2010. The control group consisted of 27,132 randomly selected (age- and gender)-matched patients without PUD. The association between PUD and the risk of developing osteoporosis was estimated using a Cox proportional hazard regression model. During the follow-up period, osteoporosis was diagnosed in 2538 (9.35 %) patients in the PUD group and in 2259 (8.33 %) participants in the non-PUD group. After adjusting for covariates, osteoporosis risk was 1.85 times greater in the PUD group compared to the non-PUD group (13.99 vs 5.80 per 1000 person-years, respectively). Osteoporosis developed 1 year after PUD diagnosis. The 1-year follow-up period exhibited the highest significance between the 2 groups (hazard ratio [HR] = 63.44, 95% confidence interval [CI] = 28.19-142.74, P < 0.001). Osteoporosis risk was significantly higher in PUD patients with proton-pump-inhibitors (PPIs) use (HR = 1.17, 95% CI = 1.03-1.34) compared to PUD patients without PPIs use. This study revealed a significant association between PUD and subsequent risk of osteoporosis. Therefore, PUD patients, especially those treated with PPIs, should be evaluated for subsequent risk of osteoporosis to minimize the occurrence of adverse events.

Gastric urease was studied isotopically in 230 patients with biopsy-proven normal mucosa or chronic gastritis, including 59 patients with ulcer disease. Carbon-14-urea was given in 25 ml of water without substrate carrier or nutrient-dense meal, and breath samples were collected over a 60-min period. The amount of 14CO2 excreted at 10 min was independent of the rate of gastric emptying and was not quantitatively influenced by the buccal urease activity. The 10-min 14CO2 values discriminated well between Helicobacter pylori positive and negative patients (94% sensitivity, 89% specificity) and correlated with the number of organisms assessed by histology. The test was a good predictor of chronic gastritis (95% sensitivity and 96% specificity), and a quantitative relationship was observed between 14CO2 values and the severity and activity of the gastritis. In H. pylori positive patients, breath 14CO2 was found to be similar in patients with and without ulcer disease, suggesting that the number of bacteria is not a determining factor for the onset of ulceration.

To investigate whether Helicobacter pylori (H pylori) eradication would influence the risk of primary open angle glaucoma (POAG) in patients with peptic ulcer disease. From the Longitudinal Health Insurance Database 2000, 6061 patients with peptic ulcer and receiving H pylori eradication therapy were recruited. The study cohort was subdivided into early (within 1 year) and late (after 1 year) eradication cohorts. The 24,244 control cohort subjects were those who without peptic ulcer and without receiving H pylori eradication therapy and were frequency-matched with the H pylori eradication cohort by age, sex, and the year of receiving H pylori eradication therapy. The higher incidence of POAG was observed in late H pylori eradication cohort and in early H pylori eradication cohort than in control cohort (1.57, 1.32, and 0.95, per 1000 person-year, respectively). However, overall risk of glaucoma was not significantly higher in the late eradication than in the early eradication (adjusted hazard ratio = 0.85, 95% confidence interval = 0.48-1.53). The POAG incidence was greater in the late H pylori eradication cohort when follow-up duration ≤ 5 years (1.59, per 1000 person-years). However, when follow-up duration >5 years, the incidence of POAG was greater in the early H pylori eradication cohort (1.68, per 1000 person-years). These relationships were not associated with a significantly increased or decreased risk of POAG in multivariable analyses. Either early or late H pylori eradication does not significantly reduce the risk of glaucoma in patients with peptic ulcer disease compared with normal control.

Recent intervention of nonspecific genital ulcers has added refreshing dimensions to genital ulcer disease. It was considered pertinent to dwell on diverse clinical presentation and diagnostic strategies. It seems to possess spectrum. It includes infective causes, Epstein Bar Virus, tuberculosis, Leishmaniasis, HIV/AIDS related ulcers and amoebiasis. Noninfective causes are immunobullous disorders, aphthosis, Behcet's disease (BD), inflammatory bowel disease, lichen planus and lichen sclerosis et atrophicus, drug reactions, premalignant and malignant conditions, pyoderma gangrenosum, and hidradenitis suppurativa. The diagnostic features and treatment option of each disorder are succinctly outlined for ready reference.

Mast cells secrete numerous mediators and this study investigated plasma levels of histamine, and tumor necrosis factor alpha (TNF-α) in chronic inflammatory bowel disease (IBD). Plasma levels of histamine were determined in 68 patients with Crohn's disease (CD), 22 with ulcerative colitis (UC) and 13 controls. TNF-α levels were assessed in 29 CD patients, 11 UC patients, and in 11 controls. Plasma histamine levels in the control group were 0.25 ng (0.14 - 0.33) and showed no difference to CD (0.19 ng, 0.09 - 0.35) or UC (0.23 ng, 0.11 - 0.60). Significantly lower histamine levels were only found in CD patients on 5-aminosalicylic acid treatment (P ≤ 0.04). Plasma TNF-α levels in the control group were significantly lower 0.44 ml/m(2) (0 - 1.15) than in CD patients (4.62 ml/m(2), 1.82 - 9.22, P = 0.005) or UC (3.14 ml/m(2); 0.08 - 11.34, P = 0.01). In CD disease activity, fistula, and extraintestinal manifestations (EM) were associated with significantly higher plasma TNF-α values, but not the type of treatment. We concluded that in contrast to TNF-α, histamine levels were normal in CD and UC. There is no correlation with histamine and thus the proportion of TNF-α secreted from mast cells in the plasma in patients with IBD is less important.

Full Text Available Background: Helicobacter pylori (H. pylori infection is a risk factor for peptic ulcer. There have been no studies addressing environmental and dietary risk factors in western India. We conducted a case control study enrolling peptic ulcer patients in Pune, India. Materials and Methods: Risk factors for peptic ulcer and H. pylori infection were assessed in a participant interview. H. pylori status was assessed from stool by monoclonal antigen detection. Results: We enrolled 190 peptic ulcer, 35 stomach cancer patients, and 125 controls. Fifty-one percent (180/350 of the participants were infected with H. pylori. Lower socioeconomic status (SES [odds ratio (OR: 1.10, 95% confidence interval (CI: 1.02-1.39], meat consumption (OR: 2.35, 95% CI: 1.30-4.23, smoking (OR: 2.23, 95% CI: 1.24-4.02, eating restaurant food (OR: 3.77, 95% CI: 1.39-10.23, and drinking nonfiltered or nonboiled water (OR: 1.05, 95% CI: 1.01-1.23 were risk factors for H. pylori infection. H. pylori infection (OR: 1.70, 95% CI: 1.03-2.89, meat (OR: 1.10, 95% CI: 1.02-1.75, fish (OR: 1.05, 95% CI: 1.02-1.89 consumption, and a family history of ulcer (OR: 1.20, 95% CI: 1.08-1.60 were risk factors for peptic ulcer. Consumption of chili peppers (OR: 0.20, 95% CI: 0.10-0.37 and parasite infestation (OR: 0.44, 95% CI: 0.24-0.80 were protective against H. pylori infection. Conclusion: H. pylori infection is associated with peptic ulcer. Lower SES, consumption of restaurant food, meat, nonfiltered water, and smoking are risk factors for H. pylori. Consumption of meat, fish, and a family history of peptic ulcer are risk factors for peptic ulcer. Consumption of chili peppers and concurrent parasite infestation appear to be protective against H. pylori.

Health care workers (HCWs) in Taiwan have heavy, stressful workloads, are on-call, and have rotating nightshifts, all of which might contribute to peptic ulcer disease (PUD). We wanted to evaluate the PUD risk in HCWs, which is not clear. Using Taiwan's National Health Insurance Research Database, we identified 50,226 physicians, 122,357 nurses, 20,677 pharmacists, and 25,059 other HCWs (dieticians, technicians, rehabilitation therapists, and social workers) as the study cohort, and randomly selected an identical number of non-HCW patients (i.e., general population) as the comparison cohort. Conditional logistical regression analysis was used to compare the PUD risk between them. Subgroup analysis for physician specialties was also done. Nurses and other HCWs had a significantly higher PUD risk than did the general population (odds ratio [OR]: 1.477; 95% confidence interval [CI]: 1.433-1.521 and OR: 1.328; 95% CI: 1.245-1.418, respectively); pharmacists had a lower risk (OR: 0.884; 95% CI: 0.828-0.945); physicians had a nonsignificantly different risk (OR: 1.029; 95% CI: 0.987-1.072). In the physician specialty subgroup analysis, internal medicine, surgery, Ob/Gyn, and family medicine specialists had a higher PUD risk than other physicians (OR: 1.579; 95% CI: 1.441-1.731, OR: 1.734; 95% CI: 1.565-1.922, OR: 1.336; 95% CI: 1.151-1.550, and OR: 1.615; 95% CI: 1.425-1.831, respectively). In contrast, emergency physicians had a lower risk (OR: 0.544; 95% CI: 0.359-0.822). Heavy workloads, long working hours, workplace stress, rotating nightshifts, and coping skills may explain our epidemiological findings of higher risks for PUD in some HCWs, which might help us improve our health policies for HCWs.

Roxatidine (150 mg, 312 patients) was compared with ranitidine (300 mg, 308 patients) in a randomized, double-blind, parallel-group, 6-week therapeutic study for the treatment of patients with uncomplicated, benign gastric ulcer disease. The study end points (verified by using endoscopy results) were fully healed ulcers at 4 or 6 weeks. The results of roxatidine therapy were comparable to those of ranitidine therapy: healing rates of 52% and 54% at week 4 and 77% and 76% at week 6 were recorded for roxatidine and ranitidine, respectively. The drugs produced comparable reductions in ulcer diameters and decreases in abdominal pain. Adverse events associated with both roxatidine (27%) and ranitidine (28%) were headache, diarrhea, and dizziness; rash was associated in 6 of 8 cases and in only 1 case with roxatidine. In this trial, roxatidine 150 mg once daily was as efficacious and safe as ranitidine 300 mg once daily for treatment of patients with uncomplicated, benign gastric ulcer disease.

Connective tissue disorders (CTD), which are often also termed collagen vascular diseases, include a number of related inflammatory conditions. Some of these diseases include rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis (scleroderma), localized scleroderma (morphea variants localized to the skin), Sjogren's syndrome, dermatomyositis, polymyositis, and mixed connective tissue disease. In addition to the systemic manifestations of these diseases, there are a number of cutaneous features that make these conditions recognizable on physical exam. Lower extremity ulcers and digital ulcers are an infrequent but disabling complication of long-standing connective tissue disease. The exact frequency with which these ulcers occur is not known, and the cause of the ulcerations is often multifactorial. Moreover, a challenging component of CTD ulcerations is that there are still no established guidelines for their diagnosis and treatment. The morbidity associated with these ulcerations and their underlying conditions is very substantial. Indeed, these less common but intractable ulcers represent a major medical and economic problem for patients, physicians and nurses, and even well organized multidisciplinary wound healing centers.

biomarkers are currently needed for identification of patients with mild or moderate disease activity. Using a commercially available platform, we aimed at identifying serum biomarkers that are able to grade the disease severity. METHODS: Serum samples from 65 patients with UC with varying disease activity......-stimulating factor produced a predictive model with an AUC of 0.72 when differentiating mild and moderate UC, and an AUC of 0.96 when differentiating moderate and severe UC, the latter being as reliable as CRP. CONCLUSIONS: Alpha-1 antitrypsin is identified as a potential serum biomarker of mild-to-moderate disease......BACKGROUND: Initial assessment of patients with ulcerative colitis (UC) is challenging and relies on apparent clinical symptoms and measurements of surrogate markers (e.g., C-reactive protein [CRP] or similar acute phase proteins). As CRP only reliably identifies patients with severe disease, novel...

The aim of this study was to investigate the identity of the Helicobacter heilmannii-like bacteria found in the stomach of a human patient suffering from stomach ulcers and her asymptomatic pet dog. An elderly woman was referred for gastroscopy because of right hypochondrial pain, nausea, anorexia and vomiting. Gastric ulcers were observed and histology revealed the presence of multiple H. heilmannii-like bacteria. Multiplex polymerase chain reaction (PCR) identified the bacteria as H. felis. Her pet dog was also examined gastroscopically. Only mild gastric lesions were found but PCR showed the presence of H. felis as well as H. bizzozeronii and Candidatus H. heilmannii. This report associates H. felis infection in humans with severe gastric ulceration. Moreover, the suggestion can be made that the patient contracted H. felis from her dog.

Previous reports differ as to whether a decreased elongation index (EI), a proxy for red blood cell (RBC) deformability, is associated with leg ulcers (LU) in people with homozygous sickle cell disease (SCD). We sought to determine whether erythrocyte deformability (ED) and haematological indices were associated with the presence of LU in patients with SCD. The study design was cross-sectional. Twenty-seven patients with LU and 23 with no history of ulceration were recruited into the study. A laser assisted rotational red cell analyzer was used in the determination of the EI. Haematological indices were determined using a CELL-DYN Ruby haematology analyzer. Data were normally distributed and presented as means±SD. Two-sample t-test was used to test for associations between haemorheological variables in SCD patients with and without LU. Statistical significance was taken as p < 0.05. The EI was significantly lower in the group with ulcers (0.30±0.07 vs. 0.35±0.07, p = 0.02). Haematological indices were comparable in patients with and without LU. Erythrocyte deformability, but not haematological indices, was associated with LU in patients with SCD.

Gastrointestinal bleeding and iron deficiency anaemia may cause severe symptoms and may require extensive diagnostics and substantial amounts of health resources.This case report focuses on the clinical presentation of a 22 year old patient with recurrent gastrointestinal bleeding from multilocular non-healing ulcers of the stomach, duodenum and jejunum over a period of four years. Extensive gastroenterological and allergological standard diagnostic procedures showed benign ulcerative lesions with tissue eosinophilia, but no conclusive diagnosis. Multiple diagnostic procedures were performed, until finally, endoscopically guided segmental gut lavage identified locally produced, intestinal IgE antibodies by fluoro-enzyme-immunoassay.IgE antibody concentrations at the intestinal level were found to be more-fold increased for total IgE and food-specific IgE against nuts, rye flour, wheat flour, pork, beef and egg yolk compared with healthy controls.Thus, a diet eliminating these allergens was introduced along with antihistamines and administration of a hypoallergenic formula, which resulted in complete healing of the multilocular ulcers with resolution of gastrointestinal bleeding. All gastrointestinal lesions disappeared and total serum IgE levels dropped to normal within 9 months. The patient has been in remission now for more than two years.Eosinophilic gastroenteritis (EG) is well known to induce refractory ulcer disease. In this case, the mechanisms for intestinal damage and gastrointestinal bleeding were identified as local gastrointestinal type I allergy. Therefore, future diagnostics in EG should also be focused on the intestinal level as identification of causative food-specific IgE antibodies proved to be effective to induce remission in this patient.

A range of 5-ASA preparations is available and Eudragit-S® coated modified release formulations of mesalamine, such as Asacol®, remain among the most popular choices. We here review the current understanding of the mechanism of action of 5-ASA in inflammatory bowel disease. We evaluate evidence supporting the efficacy and safety of modified release mesalamine for both induction and remission maintenance in UC, including a review of the data from the recent ASCEND studies. We also examine the controversial issue of the role of mesalamine in treatment of Crohn’s disease (CD and highlight data supporting its use following surgically induced remission of CD. Evidence supporting the use of mesalamine as prophylaxis for colorectal cancer and dysplasia will be considered. Finally, recent developments in our understanding of how to use modified release mesalamine in a safe and cost-effective manner are evaluated, including discussion of the importance of studying patient non-adherence as a key component of future studies in this area.Keywords: mesalamine (mesalazine, 5-aminosalicyclate, ulcerative colitis, Crohn’s disease, modified release

The bacterial pathogen Helicobacter pylori is the etiological agent of a range of gastrointestinal pathologies including peptic ulcer disease and the major killer, gastric adenocarcinoma. Infection with this bacterium induces a chronic inflammatory response in the gastric mucosa (gastritis). It is this gastritis that, over decades, eventually drives the development of H. pylori-associated disease in some individuals. The majority of studies investigating H. pylori pathogenesis have focused on factors that promote disease development in infected individuals. However, an estimated 85% of those infected with H. pylori remain completely asymptomatic, despite the presence of pathogenic bacteria that drive a chronic gastritis that lasts many decades. This indicates the presence of highly effective regulatory processes in the host that, in most cases, keeps a check on inflammation and protect against disease. In this minireview we discuss such known host factors and how they prevent the development of H. pylori-associated pathologies.

Diabetic peripheral artery disease and diabetic foot ulcers are leading causes of hospitalization, for patients with diabetes mellitus, and also are the most important causes of amputation of the lower extremity in those patients, which contribute to the increased mortality and cardiovascular death. The incidence of diabetic peripheral artery disease and diabetic foot ulcers shows increasing trend. Diabetic peripheral artery disease and diabetic foot ulcers can be successfully treated only by the multidisciplinary foot-care services which provide more comprehensive and integrated care as compared to ordinary medical team or single specialist. Multidisciplinary foot-care services are provided by the team consist of: diabetologist, diabetes nurse, vascular surgeon, general surgeon, orthopedist, orthopaedic surgeon, podiatrist and orthotist, interventional radiologist and a radiology coordinator, microbiologist, psychologist, educators, shoemaker and rehabilitation team. Contrary to developed countries, multidisciplinary foot-care team has not been constructed in most centres in China. Diabetic education, appropriate foot care, early detection of risk factors of foot ulcers and early intervention are key components in the overall management of diabetic foot disorders and have assumed important roles in programs focused on amputation prevention. Prompt and aggressive treatments of diabetic peripheral artery disease and diabetic foot ulcers can often prevent an exacerbation of the problem and the potential need for amputation, which include correction of biomechanical abnormalities, infection control, serial debridement of ulcers, peripheral revascularization and wound coverage, etc. It is very important to construct a multidisciplinary diabetic foot care team to more effectively improve the survival and prognosis of patients with diabetic peripheral artery disease and diabetic foot ulcers with comprehensive treatments.

Postherpetic neuralgia is the most common complication of herpes zoster which is caused by a reactivation of latent varicella zoster virus. The pathogenesis of postherpetic neuralgia may involve peripheral and central mechanisms. Reported risk factors for postherpetic neuralgia include female gender, old age, diminished cell-mediated immunity and nutritional deficiencies. Based on our clinical observation which revealed that peptic ulcer disease (PUD) is one of the common comorbidities in patients with postherpetic neuralgia, we hypothesize that herpes zoster patients with PUD may be at a greater risk for the development of postherpetic neuralgia due to their impaired cellular immunity and depressed nutritional status. Major causes of PUD include Helicobacter pylori infection and usage of ulcerogenic medications. Patients with H. pylori infection may develop T cell dysfunctions and nutritional deficiencies including vitamin C, iron, cobalamin, carotenes and alpha-tocopherol. Ulcerogenic medications such as nonsteroidal anti-inflammatory drugs and steroids have been found not only to be ulcerogenic but also immunosuppressive to T cells. In addition, usage of steroids and nonsteroidal anti-inflammatory drugs may cause deficiencies of alpha-tocopherol, carotenes, cobalamin, iron, zinc and vitamin C. Vitamin C, carotenes and alpha-tocopherol are anti-inflammatory and the major oxidant scavengers in the aqua phase and biomembranes. Deficiencies of these nutrients may induce dysregulated inflammation and oxidative damage leading to neuropathic pain in patients with herpes zoster. Furthermore, nutrient deficiencies including zinc, iron, cobalamin and vitamin C are associated with dysregulation of Ca(v)3.2 T-channels and N-methyl-D-aspartate receptors, upregulation of nitric oxide synthase, the increase of nitric oxide formation and dysfunction of central norepinephrine inhibitory pain pathway. Prospective cohort studies are suggested to test the hypothesis. We further

Full Text Available BACKGROUND: H. pylori causes gastritis and peptic ulcers and is a risk factor for the development of gastric carcinoma. Many of the proteins such as urease, porins, flagellins and toxins such as lipo-polysaccharides have been identified as potential virulence factors which induce proinflammatory reaction. We report immunogenic potentials of isocitrate dehydrogenase (ICD, an important house keeping protein of H. pylori. METHODOLOGY/PRINCIPAL FINDINGS: Amino acid sequences of H. pylori ICD were subjected to in silico analysis for regions with predictably high antigenic indexes. Also, computational modelling of the H. pylori ICD as juxtaposed to the E. coli ICD was carried out to determine levels of structure similarity and the availability of surface exposed motifs, if any. The icd gene was cloned, expressed and purified to a very high homogeneity. Humoral response directed against H. pylori ICD was detected through an enzyme linked immunosorbent assay (ELISA in 82 human subjects comprising of 58 patients with H. pylori associated gastritis or ulcer disease and 24 asymptomatic healthy controls. The H. pylori ICD elicited potentially high humoral immune response and revealed high antibody titers in sera corresponding to endoscopically-confirmed gastritis and ulcer disease subjects. However, urea-breath-test negative healthy control samples and asymptomatic control samples did not reveal any detectable immune responses. The ELISA for proinflammatory cytokine IL-8 did not exhibit any significant proinflammatory activity of ICD. CONCLUSIONS/SIGNIFICANCE: ICD of H. pylori is an immunogen which interacts with the host immune system subsequent to a possible autolytic-release and thereby significantly elicits humoral responses in individuals with invasive H. pylori infection. However, ICD could not significantly stimulate IL8 induction in a cultured macrophage cell line (THP1 and therefore, may not be a notable proinflammatory agent.

We evaluated parameters of apoptosis in the mucosa of the gastric antrum and body of indigenous and non-indigenous residents of Khakassia with duodenal ulcer disease associated with Helicobacter pylori infection. In the gastric antrum, apoptotic index was significantly increased in patients with ulcer disease in comparison with healthy individuals in both populations. The ratio of proliferation index to apoptotic index was lower in patients with ulcer disease in comparison with healthy individuals in both populations. Similar, but less pronounced processes were recorded in the body of the stomach. Significant changes in the parameters of proliferation and apoptosis were noted in the gastric antrum and body of the stomach in both populations, but they were more pronounced in Caucasians in comparison with Khakasses.

The aim of the study was to evaluate iloprost infusion as an alternative to open surgical revascularisation in diabetic patients with foot ulcers, also as a support measure in conjunction with endovascular procedures. We studied 244 patients with critical ischaemia of the lower limbs, 146 of whom (59.8%) affected by diabetes. A femoro-distal bypass was performed in 175 patients. In the 69 nonsurgical diabetic patients (47.3% of the diabetics) an iloprost infusion was started. These diabetics presented foot ulcers, a palpable or slightly hypo-sphygmic popliteal pulse and high distal arterial flow at the ankle. In 55 of these patients (79.7% of those not operated on and 37.6% of the diabetics) who were non-responders to medical therapy, an endovascular procedure was also performed. The results of the iloprost infusion (69 pts.) were evaluated after one week. In 14 responders treated only with iloprost infusion, complete healing of the lesions occurred during the 3 weeks following the end of the 4-week course of therapy. No severe ischaemia recurrences were reported in the follow-up of these 69 patients. In the 47.3% of subjects with diabetic arteriopathy presenting foot ulcers and high distal flow, it proved possible to avoid an open surgical revascularisation procedure and to resort to medical therapy with iloprost, completed in 79.7% of cases with endovascular procedures. Iloprost infusion improves limb perfusion and, in selected cases may be an important therapeutic tool for the care of ulcerative lesions of the diabetic foot, also as a support measure in conjunction with endovascular procedures.

OBJECTIVE: To retrospectively determine the prevalence and the factors predicting erosive esophagitis and severe esophagitis in a large series of endoscopies in Spain. DESIGN: Retrospective observational study. A multivariate analysis was performed to determine variables predicting severe esophagitis. SETTING: Databases of 29 Spanish endoscopy units. PATIENTS: Patients submitted to a diagnostic endoscopy during the year 2005. INTERVENTIONS: Retrospective review of the databases. MAIN OUTCOME MEASUREMENTS: Esophagitis severity (graded according to the Los Angeles classification and associated endoscopic findings. RESULTS: Esophagitis was observed in 8.7% of the 93,699 endoscopies reviewed. Severe esophagitis (LA grade C or D accounted for 22.5% of cases of the disease and was found in 1.9% of all endoscopies. Incidences of esophagitis and those of severe esophagitis were 86.2 and 18.7 cases per 100,000 inhabitants per year respectively. Male sex (OR 1.89 and advanced age (OR 4.2 for patients in the fourth age quartile were the only variables associated with severe esophagitis. Associated peptic ulcer was present in 8.8% of cases. LIMITATIONS: Retrospective study, no data on individual proton pump inhibitors use. CONCLUSIONS: Severe esophagitis is an infrequent finding in Spain. It occurs predominantly in males and in older individuals. Peptic ulcer disease is frequently associated with erosive esophagitis.

The burden of diabetic foot disease(DFD) is expected to increase in the future. The incidence of DFD is still rising due to the high prevalence of DFD predisposing factors. DFD is multifactorial in nature; however most of the diabetic foot amputations are preceded by foot ulceration. Diabetic peripheral neuropathy(DPN) is a major risk factor for foot ulceration. DPN leads to loss of protective sensation resulting in continuous unconscious traumas. Patient education and detection of high risk foot are essential for the prevention of foot ulceration and amputation. Proper assessment of the diabetic foot ulceration and appropriate management ensure better prognosis. Management is based on revascularization procedures, wound debridement, treatment of infection and ulcer offloading. Management and type of dressing applied are tailored according to the type of wound and the foot condition. The scope of this review paper is to describe the diabetic foot syndrome starting from the evaluation of the foot at risk for ulceration, up to the new treatment modalities.

Major hemoglobinopathies, including sickle cell anemia, are becoming a global health issue. Leg ulcers are the most common cutaneous manifestation of sickle cell disease and an important contributor to morbidity burden in this population. Leg ulcers following sickling disorders are extremely painful, and hard to heal. The clinical evidence for the optimal management of these ulcers is limited. Treating the cause and the strategies to prevent sickling are the mainstay of treatment. The basic principles of wound bed preparation and compression therapy is beneficial in these patients.

Background Clinical diagnosis of Buruli ulcer (BU) due to Mycobacterium ulcerans can be challenging. We aimed to specify the differential diagnosis of skin lesions in a BU endemic area. Method We conducted a prospective diagnostic study in Akonolinga, Cameroon. Patients presenting with a skin ulcer suspect of BU were included. M. ulcerans was detected using swabs for Ziehl-Neelsen staining, PCR and culture. Skin punch biopsies were taken and reviewed by two histopathologists. Photographs of the lesions were taken and independently reviewed by two dermatologists. Final diagnosis was based on consensus, combining the results of laboratory tests and expert opinion. Results/ Discussion Between October 2011 and December 2013, 327 patients with ulcerative lesions were included. Median age was 37 years (0 to 87), 65% were males, and 19% HIV-positive. BU was considered the final diagnosis for 27% of the lesions, 85% of which had at least one positive laboratory test. Differential diagnoses were vascular lesions (22%), bacterial infections (21%), post-traumatic (8%), fistulated osteomyelitis (6%), neoplasia (5%), inflammatory lesions (3%), hemopathies and other systemic diseases (2%) and others (2%). The proportion of BU was similar between HIV-positive and HIV-negative patients (27.0% vs. 26.5%; p = 0.940). Half of children below 15 years of age were diagnosed with BU, compared to 26.8% and 13.9% among individuals 15 to 44 years of age and above, respectively (chi2 p<0.001). Children had more superficial bacterial infections (24.3%) and osteomyelitis (11.4%). Conclusion We described differential diagnosis of skin lesions in a BU endemic area, stratifying results by age and HIV-status. PMID:27074157

Full Text Available BACKGROUND: Medical male circumcision (MMC reduces the risk of genital ulcer disease (GUD in men by 50%. In Ugandan and Kenyan trials, a sexually transmissible agent was not identified in 50-60% of GUD specimens by polymerase chain reaction (PCR assay. We sought to better define the etiology of GUD in men participating in the Kenyan trial and examine how MMC affects GUD etiology. METHODS: We defined GUD of unknown etiology as negative for HSV (type 1 and type 2, T. pallidum, and H. ducreyi by PCR, and negative for HSV-2 and T. pallidum by serology. We identified bacterial microbiota in a subset of 59 GUD specimens using multitag pyrosequencing of the 16S rRNA gene, and compared results by unknown vs. STI-associated etiology. Statistical analysis employed Bray-Curtis similarity measure of bacterial community by etiology, hierarchical clustering and logistic regression. RESULTS: In 59 GUD specimens from 59 men, 23 (39% had unknown etiology. Bacterial diversity was greater in GUD of unknown than STI etiology (p = 0.01. Fusobacteria (Fusobacterium spp. and Sneathia spp. were more commonly detected in men with GUD of unknown etiology [adjusted OR = 5.67; 95% CI: 1.63-19.8] as were Oxobacter spp. and Anaerovorax spp. [adjusted OR = 3.12; 95% CI: 0.83-11.7]. Sequences from these four anaerobic bacterial taxa were more often detected in uncircumcised men than circumcised men (p<0.05. CONCLUSIONS: Anaerobic bacteria are more common in genital ulcers of uncircumcised men. The specific anaerobic bacteria associated with GUD of unknown etiology have cytotoxic properties that can exacerbate epithelial disruptions leading to ulcer-like appearance. MMC may reduce GUD through a reduction in these anaerobic bacteria.
Full Text Available Inflammatory bowel disease (IBD, ulcerative colitis (UC and Crohn's disease, is reported to be associated with impaired health-related quality of life (QOL. Although decreased QOL in these subjects has been reported to be associated with various factors, the effect of nutritional therapy, especially nutrients intake on QOL has received less attention. In this study, we evaluated the various factors including nutrients intake on QOL using SF-8 in 64 patients with IBD. Patients with IBD seem to have decreased QOL especially in the mental aspects. The percentage energy intake from fat of total energy fat intake (% energy of the whole subjects, was lower than those of the annual National Nutrition Survey in Japan. Multiple regression analyses revealed that fat intake (% energy was a significant predictor for mental component summary. In conclusion, fat restriction contributes to impaired QOL especially in the mental aspects in IBD patients.
Helicobacter pylori infection induces chronic inflammation of the gastric mucosa and thus profoundly affects gastric physiology. In the acute phase of infection, gastric acid secretion is transiently impaired. The morphological damage of the gastric mucosa, changes in gastric hormone release, and disruption of neural pathways all contribute to influence gastric acid secretion in a distinct manner. Changes in gastric acid secretion, whether impaired or increased, are intimately related with the topographic phenotypes of gastritis and the presence of atrophy or absence of corpus atrophy. The interplay of gastritis phenotype and acid secretion are key determinants in disease outcomes. Corpus-predominant gastritis and corpus atrophy are accompanied by hypochlorhydria and carry the highest risk for gastric cancer, whereas antrum-predominant gastritis with little involvement of the corpus-fundic mucosa is associated with hyperchlorhydria and predisposes to duodenal ulcer disease.

Abstract Persistent exacerbation of a peptic ulcer may lead to a complicated peptic ulcer (perforation or/and bleeding). The management of complicated peptic ulcers has shifted from acid-reducing vagotomy, drainage, and gastrectomy to simple local suture or non-operative (endoscopic/angiographic) hemostasis. We were interested in the long-term effects of this trend change. In this study, complicated peptic ulcer patients who received acid-reducing vagotomy were compared with those who receive...

Full Text Available Abstract Background The relapsing nature and varying geographical prevalence of ulcerative colitis (UC implicates environmental factors such as diet in its aetiology. Methods In order to determine which foods might be related to disease activity in UC a new method of dietary analysis was developed and applied. Eighty-one UC patients were recruited at all stages of the disease process. Following completion of a 7 d diet diary, clinical assessment including a sigmoidoscopic examination (scale 0 (normal mucosa to 6 (very active disease was conducted. Food weights for each person were adjusted (divided by the person's calorific intake for the week. Each food consumed was given a food sigmoidoscopy score (FSS calculated by summing the products of the (adjusted weight of food consumed and sigmoidoscopy score for each patient and occurrence of food and dividing by the total (adjusted weight of the food consumed by all 81 patients. Thus, foods eaten in large quantities by patients with very active disease have high FSSs and vice versa. Foods consumed by Results High FSS foods were characterized by high levels of the anti-thiamin additive sulfite (Mann-Whitney, p Conclusions The dietary analysis method described provides a new tool for establishing relationships between diet and disease and indicates a potentially therapeutic diet for UC.

Full Text Available Despite intensive research we remain ignorant of the cause of both Crohn’s disease and ulcerative colitis. The dramatic rise in incidence, particularly of Crohn’s disease, points towards environmental factors as playing a significant role. A major purpose of this review is to stimulate a co-ordinated international effort to establish an on-going data base in Central and South America in which new cases are registered and through which investigations into aetiology can be conducted. In both Brazil and Mexico there is evidence that the incidence of ulcerative colitis is increasing, as also is the case for Crohn’s disease in Brazil. The pattern of disease is, therefore, directly comparable to that reported from Europe and the USA during the 1970s and 1980s, but much lower than contemporary data from Spain. Although the incidence is similar to that reported from Portugal, the studies from Almada and Braga were conducted a decade before that from Sao Paulo. The situation in Brazil compares dramatically with Uruguay and Argentina where the reported incidence of inflammatory bowel disease is significantly less. However, with growing industrialisation it is likely that there will be an explosion of inflammatory bowel disease in some areas of Central and South America over the next 20 years. The creation of a network of researchers across South and Central America is a real possibility and through a Concerted Action there is the possibility that major strides could be made towards understanding the cause of inflammatory bowel disease and so develop preventive strategies.

BACKGROUND Although Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs) are the main causes of peptic ulcers disease (PUD), recently the prevalence of idiopathic peptic ulcer (IPU) is increasing in most parts of the world. The aim of this study was to assess the prevalence of IPU in Kerman, the center of largest province in south-east Iran. METHODS We included 215 patients with peptic ulcer in our study. Combined methods rapid urease test (RUT), histology, and real time polymerase chain reaction (PCR) was performed on endoscopic samples of peptic ulcers. NSAID use was determined by medical history. SPSS software version 16 was used for data analysis. p valueulcer, four (1.8%) had H.pylorinegative and NSAID-negative PUD. There were not significant differences between patients with IPU and patients with peptic ulcer associated with H.pylori or NSAIDs regarding the sex, age, cigarette smoking, and opioid abuse. CONCLUSION Our study showed that in contrast to other reports from western and some Asian countries, the prevalence of IPU is low in Kerman and H.pylori infection is still the major cause of PUD. We recommend a large and multi-central study to determine the prevalence of IPU in Iran.

Abstract Objective: The infliximab biosimilar CT-P13 (Remsima®, Inflectra®) was approved in Europe for the treatment of inflammatory bowel disease (IBD) based on extrapolation of data from patients with rheumatic disease. Because there are limited published reports on clinical outcomes for IBD patients treated with CT-P13, we monitored responses to induction treatment with this biosimilar in patients with Crohn’s disease (CD) or ulcerative colitis (UC) in centres across the Czech Republic. Material and methods: Fifty-two patients with CD (n = 30) or UC (n = 22) were treated with 5 mg/kg CT-P13 for up to 14 weeks. Effectiveness of therapy was evaluated with the Crohn’s Disease Activity Index (CDAI) or the Mayo Scoring System (MSS) in patients with CD or UC, respectively, before and after 14 weeks. Additional goals were to evaluate weight changes, serum C-reactive protein (CRP) levels, and complications/adverse events. Results: In patients with CD, remission (CDAI herpes labialis, pneumonia and allergic reaction. Conclusions: This prospective observational study provides evidence of the effectiveness of CT-P13 in IBD. PMID:27002981

Ulcerative keratitis is frequently associated with collagen vascular diseases and presents a predilection for peripheral corneal localization, due to the distinct morphologic and immunologic features of the limbal conjunctiva, which provides access for the circulating immune complexes to the peripheral cornea via the capillary network. Deposition of immune complexes in the terminal ends of limbal vessels initiates an immune-mediated vasculitis process, with inflammatory cells and mediators involvement by alteration of the vascular permeability. Peripheral ulcerative keratitis generally correlates with exacerbations of the background autoimmune systemic disease. Associated sceritis, specially the necrotizing form, is usually observed in severe cases, which may evolve in corneal perforation and loss of vision. Although the first-line of treatment in acute phases is represented by systemic administration of corticosteroids, immunosuppressive and cytotoxic agents are necessary for the treatment of peripheral ulcerative keratitis associated with systemic diseases.

Background: Psychological profile of inflammatory bowel disease patients is not well studied in Iran. We investigated the psychological status of Iranian patients with ulcerative colitis (UC) and its relationship with disease activity and quality of life (QOL). Materials and Methods: A cross-sectional study was conducted on adult UC patients. The Lichtiger Colitis Activity Index, Hospital Anxiety and Depression Scale, General Health Questionnaire-12, and WHOQOL-BREF, were completed by the patients. Results: From 120 studied patients, 35 (29.2%), 48 (40.0%), and 46 (38.3%) had significant anxiety, depression, and psychological distress, respectively. Anxiety, depression, and psychological distress were strongly correlated with disease activity (r = 0.357 to 0.439, P < 0.01). Disease activity was negatively correlated with all QOL dimensions (r = −0.245 to −0.550, P < 0.01). Anxiety, depression, and psychological distress were also negatively correlated with all QOL domains (r = −0.356 to −0.789, P < 0.01). In the regression models, anxiety was independently associated with active disease (β = 4.150, P = 0.049). Furthermore, disease activity was associated with the physical health (β = −0.371, P < 0.001). For almost all of the QOL domains, depression and psychological distress were independent predictors (β = −0.296 to −0.453, P < 0.001). Conclusion: Anxiety, depression, and psychological distress are highly frequent in UC patients of our society and are strongly associated with disease activity. Depression and psychological distress are important predictors of poor QOL in these patients. Further prospective studies, as well as clinical trials, are warranted in this regard. PMID:26600833

Full Text Available Probably due to caffeine-induced gastric acid secretion, negative effects of coffee upon various upper-gastrointestinal diseases have been precariously accepted, despite the inadequate epidemiological evidence. Our aim is to evaluate the effect of coffee consumption on four major acid-related diseases: gastric ulcer (GU, duodenal ulcer (DU, reflux esophagitis (RE, and non-erosive reflux disease (NERD based on the large-scale multivariate analysis. Of the 9,517 healthy adults, GU, DU, and RE were diagnosed by endoscopy, and NERD was diagnosed by the symptoms of heartburn and regurgitation without esophageal erosion. Associations between coffee consumption and the four disorders were evaluated, together with age, gender, body mass index (BMI, Helicobacter pylori (HP infection status, pepsinogen I/II ratio, smoking, and alcohol. We further performed meta-analysis using the random effects model to redefine the relationship between coffee intake and peptic ulcer disease. The eligible 8,013 study subjects comprised of 5,451 coffee drinkers and 2,562 non-coffee drinkers. By univariate analysis, age, BMI, pepsinogen I/II ratio, smoking, and alcohol showed significant associations with coffee consumption. By multiple logistic regression analysis, positively correlated factors with significance were HP infection, current smoking, BMI, and pepsinogen I/II ratio for GU; HP infection, pepsinogen I/II ratio, and current smoking for DU; HP non-infection, male, BMI, pepsinogen I/II ratio, smoking, age, and alcohol for RE; younger age, smoking, and female for NERD. The meta-analyses could detect any association of coffee consumption with neither GU nor DU. In conclusion, there are no significant relationship between coffee consumption and the four major acid-related upper gastrointestinal disorders.

AIM: To compare the prevalence of Helicobacter pylori (Hpylori) IgG and IgA antibodies between adult subjects,with defined gastric diseases, nondefined gastric disorders and those representing the population.METHODS: Data on H pylori IgG and IgA antibodies,determined by enzyme immunoassay, were analyzed in 3 252 subjects with DGD including 482 patients with gastric ulcer, 882 patients with duodenal ulcer, 1 525patients with chronic gastritis only and 363 subjects with subsequent gastric cancer, 19 145 patients with NoDg and4 854 POPUL subjects. The age-adjusted prevalences were calculated for 1- and 20-year age cohorts.RESULTS: The prevalences of IgG antibodies were equally high (89-96%) in all 20-year age cohorts of the DGD groups, whereas the prevalences of IgG antibodies were lower and increased by age in the POPUL and NoDg groups. The prevalences of IgA antibodies were also higher in the DGD groups; among them CA (84-89%) and GU groups (78-91%) showed significantly higher prevalences than DU (68-77%) and CG patients (59-74%) (OR 2.49, 95%CI 1.86-3.34 between the GU and DU groups). In the CA, GU, and DU groups, the IgA prevalences showed only minor variation according to age, while they increased by age in the CG, POPUL, and NoDg groups (P≤0.0001). The IgA response, but not the IgG response, was associated with an increased risk of CA (OR 2.41, 95%CI 1.79-3.53) and GU (OR 2.57,95%CI 1.95-3.39) in comparison with CG patients.CONCLUSION: An IgA antibody response during H pylori infection is significantly more common in CA and GU patients as compared with CG patients.

Four cases of peptic ulcer penetrating the head of the pancreas were diagnosed by computed tomography (CT). Findings common to 3 cases included (a) an ulcer crater, (b) a sinus tract, and (c) enlargement of the head of the pancreas. Unlike other modalities, the inherent spatial resolution of CT allows a convenient diagnosis of this important complication of peptic ulcer disease.

Demographic, laboratory parameters leading up to biologic therapy and the subsequent pattern of outcomes in either disease were established as a database. Initial failure, subsequent need to change therapy, or need to adjust therapy were evaluated. Kruskal–Wallis (nonparametric tests to compare two groups and Kaplan–Meier survival curve analysis were used to compare outcomes.Results: Over approximately 6 years, 71 CD and 26 UC patients received 999 and 215 infusions, respectively, for a median of 62 months. Of these, 17% for CD and 19% for UC patients were primary failures. Following the start of infliximab, 18% of CD and 11% of UC patients required stoppage and switching to another type of therapy. In either CD or UC patients, 54% or 62%, respectively, continued therapy without the need to change to other treatments. Few serious side effects were noted. No important statistically significant differences in treatment patterns or outcome were observed between the groups.Discussion: Long-term treatment of both inflammatory bowel diseases reflects outcomes of clinical trials.Conclusions: This study emphasizes similarities between CD and UC and reports therapeutic success for an extended time.Keywords: infliximab, inflammatory bowel diseases

Full Text Available Significant gut microbiota heterogeneity exists among ulcerative colitis (UC patients, though the clinical implications of this variance are unknown. We hypothesized that ethnically distinct UC patients exhibit discrete gut microbiotas with unique metabolic programming that differentially influence immune activity and clinical status. Using parallel 16S rRNA and internal transcribed spacer 2 sequencing of fecal samples (UC, 30; healthy, 13, we corroborated previous observations of UC-associated bacterial diversity depletion and demonstrated significant Saccharomycetales expansion as characteristic of UC gut dysbiosis. Furthermore, we identified four distinct microbial community states (MCSs within our cohort, confirmed their existence in an independent UC cohort, and demonstrated their coassociation with both patient ethnicity and disease severity. Each MCS was uniquely enriched for specific amino acid, carbohydrate, and lipid metabolism pathways and exhibited significant luminal enrichment of the metabolic products of these pathways. Using a novel ex vivo human dendritic cell and T-cell coculture assay, we showed that exposure to fecal water from UC patients caused significant Th2 skewing in CD4+ T-cell populations compared to that of healthy participants. In addition, fecal water from patients in whom their MCS was associated with the highest level of disease severity induced the most dramatic Th2 skewing. Combined with future investigations, these observations could lead to the identification of highly resolved UC subsets based on defined microbial gradients or discrete microbial features that may be exploited for the development of novel, more effective therapies.

Helicobacter pylori establishes a chronic infection in the human stomach, causing gastritis, peptic ulcer, or gastric cancer, and more severe diseases are associated with virulence genes such as the cag pathogenicity island (PAI). The aim of this work was to study gene content differences among H. pylori strains isolated from patients with different gastroduodenal diseases in a Mexican-Mestizo patient population. H. pylori isolates from 10 patients with nonatrophic gastritis, 10 patients with duodenal ulcer, and 9 patients with gastric cancer were studied. Multiple isolates from the same patient were analyzed by randomly amplified polymorphic DNA analysis, and strains with unique patterns were tested using whole-genome microarray-based comparative genomic hybridization (aCGH). We studied 42 isolates and found 1,319 genes present in all isolates, while 341 (20.5%) were variable genes. Among the variable genes, 127 (37%) were distributed within plasticity zones (PZs). The overall number of variable genes present in a given isolate was significantly lower for gastric cancer isolates. Thirty genes were significantly associated with nonatrophic gastritis, duodenal ulcer, or gastric cancer, 14 (46.6%) of which were within PZs and the cag PAI. Two genes (HP0674 and JHP0940) were absent in all gastric cancer isolates. Many of the disease-associated genes outside the PZs formed clusters, and some of these genes are regulated in response to acid or other environmental conditions. Validation of candidate genes identified by aCGH in a second patient cohort allowed the identification of novel H. pylori genes associated with gastric cancer or duodenal ulcer. These disease-associated genes may serve as biomarkers of the risk for severe gastroduodenal diseases. PMID:19237517

Full Text Available In their daily practice, psychiatrists often experience gastriccomplaints in patients beside psychiatric disorders.Peptic ulcer is one of the diseases, which accompanyto psychiatric disorders including mainly depression. Itis shown that antidepressants can inflame the bleedingsincluding gastrointestinal (GI bleedings, while they havepositive effect on ulcer healing. In this review, studies,which conducted about the positive or negative effects ofantidepressant drugs on ulcer treatment were examined.Accordingly; it was found that opipramol, amitriptyline,imipramine that of tricyclic antidepressants was found tobe helpful in healing of the ulcer. It was stated that SelectiveSerotonin Reuptake Inhibitors generally inflamedulcers, exceptionally fluvoxamine and fluoxetine reducedulcer; moclobemide that of monoamine-oxidase inhibitorand tianeptine and mirtazapine that of atypical antidepressantshad positive effect in ulcer healing. To be carefulin choosing the appropriate antidepressant in psychiatricpatients with gastric ulcer is important in the prognosisof both ulcer and depression.Key words: peptic ulcer; depression; antidepressant drugs
A short overview is presented of some of the persistent questions of the relationship of Helicobacter pylori infection and peptic ulcer disease and about the increasing number of patients with idiopathic peptic ulcer disease. The relationship between the decrease of the prevalence of peptic ulcer disease in countries with marked decrease of Helicobacter pylori prevalence in the general population, including the Czech Republic, was discussed. Several possible causes of the decrease in Helicobacter pylori prevalence were noted (improving of socioeconomic conditions, such as low income and poor education, such as poor sanitation and overcrowding, bad hygienic conditions especially during childhood, the marked increase of Helicobacter pylori eradication rate, associated also with an extended therapy by macrolides or other antibiotics (amoxicillin, etc.) used for several conditions, often at a very young age, and sometimes by chance together with proton pump inhibitors, natural loss of the older generation, which had a higher HP-prevalence than the general population, the change of the stomach microbiome, etc.) but with the implication, that the real cause of these deep changes remains indistinctly identified.

To formulate therapy goals, we aimed to define the relationship between fecal calprotectin and health-related quality of life in inflammatory bowel diseases (IBDs). This retrospective single-center cross-sectional study included ambulatory IBD patients who had completed standardized questionnaires comprising items of health-related quality of life (Short Inflammatory Bowel Disease Questionnaire) and clinical disease activity scores, and who had provided stool samples for calprotectin determination within 30 days of questionnaire completion. Correlation analyses were performed between the indicated parameters. Post hoc analysis was conducted, taking into account only data from patients with fecal calprotectin concentrations measured within 3 days of questionnaire completion. One hundred ninety-seven patients with Crohn disease and 111 patients with ulcerative colitis were enrolled in the study. Lower fecal calprotectin concentrations were associated with better health-related quality of life. The correlations were weak, but stronger if only fecal calprotectin concentrations measured within 3 days of questionnaire completion were included (results for 3 days; Crohn disease: n = 86, rS = -0.419, P calprotectin concentration and health-related quality of life was found in patients with colonic involvement (n = 59, rS = -0.470, P calprotectin concentrations and clinical disease activity were also only weak to moderate. Owing to its moderate correlation with fecal calprotectin concentrations in IBD patients with colonic involvement, health-related quality of life should be used in combination with other markers for IBD management. This is even more important in isolated ileal Crohn disease, where no significant correlation between fecal calprotectin concentration and health-related quality of life was found. Especially for use in research studies, care should be taken to keep the time between clinical evaluation of IBD patients and the determination

This multicenter randomized, double-blind, 4-wk study compared the new H2-receptor antagonistic roxatidine (R) to placebo (P) for treatment of endoscopically diagnosed active duodenal ulcer disease. Subjects were evaluated after 2 and 4 wk of treatment. Those whose ulcer was unhealed at 2 wk received 2 more weeks of treatment before final evaluation. Ulcer healing (endoscopically determined) with roxatidine was more effective than placebo at both wk 0-2 (R = 33.9%, P = 21.9%, p = 0.018) and wk 2-4 (R = 68.2%, P = 29.7%, p less than 0.001), with an overall 4-wk effectiveness of 78.9% compared to 44.8% (p less than 0.001). At the end of treatment, average maximum ulcer diameter diminished 83% in R and 50% in P (p less than 0.001). Roxatidine was also more effective than placebo in decreasing abdominal pain (p less than 0.001), decreasing the number of antacid tablets taken for pain relief (p less than 0.001), improving dyspeptic symptoms (p less than 0.001), and permitting return to a normal routine for subjects with previous illness-imposed restrictions on work and/or other daily activities. The profile of laboratory values and adverse experiences demonstrated roxatidine to be safe and well-tolerated. The efficacy of roxatidine as evaluated by the healing rate of duodenal ulcer and reduction in abdominal pain emphasize its value as an addition to the family of H2-receptor antagonists.

Full Text Available Chronic leg ulcers are rare in young adults and generally indicate a vascular cause. We report a case of a 26-year-old man with leg ulcers of eight months duration. Doppler study indicated venous incompetence and a postphlebitic limb. However, as the distribution and number of ulcers was not consistent with stasis alone and no features of collagen vascular disease were noted, a hyperviscosity state was considered and confirmed with significantly elevated homocysteine level in the serum. Administration of vitamins B1, B2, B6 and B12, trimethyl-glycine, mecobalamine, folic acid and povidone iodine dressings with culture-directed antibiotic therapy led to a satisfactory healing of ulcers over a period of one month. Hyperhomocysteinemia must be considered in the differential diagnosis of leg ulcers in young individuals.

Full Text Available Aphthous ulcer is the most common type of ulcer affecting the oral cavity and is considered to be one of the most painful conditions. Treatment is often unsatisfactory. Newer treatment modalities are therefore being tried. Amlexanox and rebamipide are the approved drugs for painful aphthous ulcers and have been used in painful symptoms of acid peptic disease as prostaglandin enhancers. Safety and efficacy of the drugs used in the treatment of recurrent aphthous ulcers were evaluated and being used widely by most of the treating physicians choosing a modality of treatment of their experience. There is no proper treatment modality available till date. Various drugs and their efficacy with least adverse drug effects while treating the various aphthous ulcers are discussed.

Inflammatory bowel diseases (IBD) are chronic and relapsing inflammatory conditions of the gastrointestinal tract including Crohn's disease (CD) and ulcerative colitis (UC). Galectins, defined by shared consensus amino acid sequence and affinity for β-galactosides, are critical modulators of the inflammatory response. However, the relevance of the galectin network in the pathogenesis of human IBD has not yet been explored. Here, we analyzed the expression of relevant members of the galectin family in intestinal biopsies, and identified their contribution as novel mucosal markers in IBD. Colonic biopsies were obtained from 59 IBD patients (22 CD and 37 UC), 9 patients with gut rejection after transplantation, 8 adult celiac patients, and 32 non-IBD donors. Galectin mRNA expression was analyzed by RT-PCR and qPCR using specific primers for individual galectins. A linear discriminant analysis (LDA) was used to analyze galectin expression in individual intestinal samples. Expression of common mucosal-associated galectins (Gal-1, -3, -4, -9) is dysregulated in inflamed tissues of IBD patients compared with non-inflamed IBD or control samples. LDA discriminated between different inflammation grades in active IBD and showed that remission IBD samples were clusterized with control samples. Galectin profiling could not distinguish CD and UC. Furthermore, inflamed IBD was discriminated from inflamed tissue of rejected gut in transplanted patients and duodenum of celiac patients, which could not be distinguished from control duodenum samples. The integrative analysis of galectins discriminated IBD from other intestinal inflammatory conditions and could be used as potential mucosal biomarker.
Full Text Available Previous studies have suggested that estrogens play a role in the development of ulcerative colitis (UC. Because isoflavones have a similar structure to 17β-estradiol, dietary consumption of isoflavones may have similar influences on the development of UC. We examined the association between pre-illness isoflavone consumption and the risk of UC.We conducted a hospital-based case control study, and compared the dietary habits of 126 newly diagnosed UC cases with those of 170 age- and gender-matched hospital controls. Information on dietary factors was collected using a self-administered diet history questionnaire. To consider potential changes in dietary habits due to disease symptoms, the habits were assessed separately during the previous 1 month and at 1 year before the recruitment.In the assessment of dietary habits during the previous 1 month, the highest tertile of isoflavone consumption revealed an increased odds ratio (OR for UC (OR = 2.79; 95% confidence interval (CI, 1.39-5.59; Trend P = 0.004. A significant association was also observed for the dietary assessment at 1 year before, when most UC cases had not yet experienced their first disease symptoms (OR = 2.06; 95% CI, 1.05-4.04; Trend P = 0.04. Associations were more pronounced in females (OR in highest tertile of isoflavone consumption at 1 year before = 4.76; 95% CI, 1.30-17.5; Trend P = 0.02 but were obscured in males (corresponding OR = 1.21; 95% CI, 0.49-3.01; Trend P = 0.63.Dietary isoflavone consumption may be associated with an increased risk of UC, particularly in females. Prospective cohort studies are warranted to confirm these findings.
Foot and mouth disease (FMD) is a highly infectious and contagious viral disease affecting bovidae (cattle, zebus, domestic buffaloes, yaks), sheep, goats, swine, all wild ruminants and suidae. Camelidae (camels, dromedaries, llamas, vicunas) have low susceptibility. Foot and mouth disease is caused by a RNS virus of the family Picornaviridae, genus Aphthovirus. There are seven immunologically distinct serotypes: A, O, C, SAT1, SAT2, SAT3, Asia 1. Foot and mouth disease causes significant economic loss both to countries who manage it as an endemic disease (with or without vaccination), as well as those FMD free countries which may become infected. The mortality rate is low in adult animals, but often higher in young due to myocarditis. Foot and mouth disease is endemic in parts of Asia, Africa, the Middle East and South America (sporadic outbreaks in free areas). The Office of International Epizootics (OIE), also referred to the World Organization for Animal Health maintains an official list of free countries and zones.1 The OIE Terrestrial Code (Chapter 2.2.10) provides detailed information on the categories of freedom that can be allocated to a country as well as guidelines for the surveillance for foot and mouth disease (Appendix 3.8.7). In short, countries may be completely free of FMD, free with vaccination or infected with foot and mouth disease virus (FMDV). Source of FMDV include incubating and clinically affected animals with virus present in breath, saliva, faeces, urine, milk and semen. In experimental settings virus has been detected in milk several days before the onset of clinical signs2. Additional sources of virus are meat and by-products in which pH has remained above 6.0 as well as persistently infected carrier animals.

Full Text Available Backgrounds: Helicobacter pylori infect more than half of the global population. It is suggested to be related with gastritis, peptic ulcer disease (PUD, and gastric cancer. Aims: The aim of this present study was to evaluate proinflammatory cytokines including interleukin 1, 6, 8, 10, and thrombomodulin in H. pylori-infected patients with PUD and gastric cancer. Patients: This cross-sectional study was conducted in Taleghani Hospital on 111 patients with H. pylori infection. Materials and Methods: Patients were divided into three groups of PUD, cancer, and control (normal on endoscopy, according to the results of endoscopy. The serum levels of interleukins 1, 6, 8, and 10 and thrombomodulin was determined using enzyme-linked immunosorbent assay (ELISA technique. H. pylori infection was diagnosed by histological examination of the endoscopic biopsy. Results: One hundred eleven patients were included in the study; 30 as PUD group, 30 as gastric cancer group, and 51 as controls. There was no significant difference between the means of IL-1 and IL-10 levels among the three groups (P = 0.744 and 0.383, respectively. IL-6, IL-8, and thrombomodulin levels were found to be statically different among the three groups (P < 0.05. The level of IL-6, IL-8, and thrombomodulin in cancer group was significantly higher than PUD and control groups (P < 0.05. Conclusion: There is a significant association between H. pylori infection and serum IL-6, IL-8, and thrombomodulin but such relation is not present between H. pylori and IL-1 and IL-10. Immunity response (IL-6, IL-8 and thrombomodulin is more severe in cancer patient than PUD.
Studies were conducted to determine the cause of the acute mortality of cage-cultured Epinephelus awoara in the Tong'an Bay of Xiamen, China during the summer of 2002. Predominant bacteria strain TS-628 was isolated from the diseased grouper. The virulence test confirmed that TS-628 was the pathogenic bacterium. Biochemical characteristics of the isolates were determined using the automatic bacterial identification system and standard tube tests. To further confirm the identification, a 1 121 bp 16S rRNA gene sequence of the isolate was amplified by PCR, which had been deposited into Genbank (accession number: AY747308). According to the biochemical characteristics and by comparing the 16S rRNA gene homology of the isolate, the pathogenic bacterium was identified as Vibrio harveyi. Drug sensitivity tests showed that this pathogenic bacterium was sensitive to 16 antibacterials, especially to chloramphenicol and actinospectacin, but completely resistant to antibacterials likes vancomycin, penicillin, lincomycin, and so on.

Sarcoidosis--a chronic, multisystem disease of unknown etiology characterized by noncaseating granulomas--may cause ulcerative lesions, particularly in African American women. A case of ulcerative sarcoidosis mimicking a venous ulcer is presented. The patient is a 44-year-old African American hypertensive, obese woman with a nonhealing medially based lower leg ulcer of 3 years' duration clinically consistent with a venous ulcer. The ulcer did not heal with compression therapy and pentoxifylline. Subsequent biopsies showed granulomatous inflammation consistent with sarcoidosis. When intralesional triamcinolone was added to compression therapy, the ulcer resolved after 3 months. Given its propensity toward formation on the lower extremities and ulcerative and atrophic appearance, ulcerative sarcoidosis should be considered in the differential diagnosis of a venous ulcer refractory to standard therapy, especially in African American women.

Full Text Available Abstract Background Escherichia coli is believed to participate in the etiology of Crohn’s disease (CD and possibly of ulcerative colitis (UC, due at least in part to the observed rise in the number of these bacteria in the gut microbiota of CD and UC patients. Nevertheless, it is not fully understood whether this quantitative variation occurs equally throughout the mucosal and luminal spaces of the gut. To assess this question, stools and mucosa biopsies from distinct intestinal sites were cultured aiming at determining their E. coli concentration. The cultures were additionally screened for the presence of some virulence genes of pathogenic E. coli. Results Analyses of clinical materials from 14 controls (38 biopsies and 14 stools samples, 11 CD (25 biopsies and 11 stools samples and 7 UC patients (18 biopsies and 7 stools samples indicated no significant variation in the number of E. coli present in stools, but a rise of at least one log10 CFU/mg in biopsies from the ileum of CD patients and the sigmoid and rectum of CD and UC patients. The cultures were screened for the presence of E. coli attaching and effacing (eae, invasion plasmid antigen H (ipaH, aggregative adherence transcriptional activator (aggR, Shiga cytotoxins (stx, and heat labile enterotoxin (elt and the following serine proteases autotransporters of Enterobacteriaceae (SPATE genes: plasmid encoded toxin (pet, secreted autotransporter toxin (sat, Shigella extracellular protein (sepA, protein involved in intestinal colonization (pic and Shigella IgA-like protease homolog (sigA. Six of the 10 genes screened were detected in the total of samples investigated: aggR, eae, pet, sat, sepA and sigA. No difference in the prevalence of any of these markers was observed in cultures from different clinical materials or groups of patients.

The authors describe the case of a 39-year-old man who presented to our hospital with easy fatigability and malaise. On physical examination, hypertension was noted without any cushingoid appearance. Laboratory testing revealed normochromic-normocytic anaemia with positive results of occult blood in the stool, hyperglycaemia and hypokalemia. Upper endoscopy revealed active gastric ulcer with Helicobacter pylori infection, likely causing gastrointestinal bleeding. Endocrine examinations showed that both serum adrenocorticotropic hormone and cortisol were elevated with loss of diurnal variation. A diagnosis of Cushing's disease secondary to pituitary adenoma was made as results of brain MRI and blood sampling from inferior petrosal sinus. In a patient with peptic ulcer disease, physician should be alert to the possible endocrine background.

Urease in the human gastric mucosa is a marker for infection with Helicobacter pylori (HP), an organism which is associated with peptic ulcer disease. To detect gastric urease, we examined 184 patients (144 males, 40 females; mean age: 49.8[+-]15.6 years) with suspected peptic ulcer disease. Fasting patients were given orally 5 [mu]Ci of carbon-14 labelled urea. For each patient only one breath sample was collected in hyamine at 10 min. The amount of [sup 14]C collected at 10 min was expressed as follows: (DPM/mmol CO[sub 2] collected)/(DPM administered)x100xbody weight (kg). The presence of HP colonization was determined by examination of multiple endoscopic prepyloric antral biopsy specimens subjected to culture or a rapid urease test. For the purpose of this study, HP-positive patients were defined as those with characteristic bacteria as indicated by a positive result of either the culture or the rapid urease test; HP-negative patients were defined as those with negative findings on both the culture and the rapid urease test. Of the 184 cases, 99 (53.8%) were positive for HP infection, and 85 (46.2%), negative. The sensitivity and specificity of the rapid 10 min [sup 14]C-urea breath test for the diagnosis of HP-associated peptic ulcer disease were evaluated by a receiver operating characteristic (ROC) curve with a variable cut-off value from 1.5 to 4.5. When a cut-off value of 1.5 was selected, the sensitivity was 100% and the specificity, 83.5%; when a cut-off value of 4.5 was selected, the sensitivity was 54.5% and the specificity, 97.6%. (orig.)

Background: Crohns disease (CD) and ulcerative colitis (UC) are characterized by a dysregulated inflammatory response to normal constituents of the intestinal flora in the genetically predisposed host. Heme oxygenase-1 (HO-1/HMOX1) is a powerful anti-inflammatory and anti-oxidant enzyme, whereas...... the pro-inflammatory interleukin 1 beta (IL-1 beta/IL1B) and anti-inflammatory interleukin 10 (IL-10/IL10) are key modulators for the initiation and maintenance of inflammation. We investigated whether single nucleotide polymorphisms (SNPs) in the IL-1 beta, IL-10, and HO-1 genes, together with smoking...

Full Text Available A 20 year old male presented with fever associated with eruption of papules, plaques and vesiculobullous lesions on the chest, back, extremities, palms, soles, and genital mucosa of 20 days duration. Histopathological examination revealed epidermal clefts, edema and vacuolar degeneration of keratinocytes, basal cell degeneration, and dermal perivascular lymphocytic infiltrate. On the basis of clinical features and histology, a diagnosis of febrile ulceronecrotic Mucha-Habermann disease (FUMHD was made. Treatment with doxycycline (100 mg BD for 4 weeks and oral prednisolone 60 mg/day tapered to 25 mg in 4 weeks led to initial response that was followed by a relapse on tapering steroid. Addition of methotrexate (7.5 mg increased to 15 mg in 2 weeks led to a dramatic response.
Full Text Available Background:Recent animal studies have identified that dietary salt intake may modify the risk and progression of autoimmune disorders through modulation of the IL23/TH17 pathway, which is critical in the pathogenesis of ulcerative colitis (UC and Crohn’s disease (CD. Methods:We conducted a prospective study of U.S. women enrolled in the Nurses’ Health Study (NHS and NHSII who provided detailed and validated information on diet and lifestyle beginning in 1984 in NHS and 1991 in NHSII. We confirmed incident cases of UC and CD reported through 2010 in NHS and 2011 in NHSII. We used Cox proportional hazards models to calculate hazard ratios (HRs and 95% confidence intervals (CIs. In a case-control study nested within these cohorts, we evaluated the interaction between single nucleotide polymorphisms (SNPs in genes involved in TH17 pathway and dietary potassium on risk of CD and UC. In a cohort of healthy volunteers, we also assessed the effect of supplemental potassium on development of naïve and memory T cells, differentiated with TGFβ1 or TH17 conditions.Results:Among a total of 194,711 women over a follow up of 3,220,247 person-years, we documented 273 cases of CD and 335 cases of UC. Dietary intake of potassium (Ptrend = 0.005 but not sodium (Ptrend = 0.44 was inversely associated with risk of CD. Although, both dietary potassium and sodium were not significantly associated with risk of UC, there was a suggestion of an inverse association with dietary potassium (Ptrend = 0.08. The association of potassium with risk of CD and UC appeared to be modified by loci involved in the TH17 pathway that have previously been associated with susceptibility to CD, particularly SNP rs7657746 (IL21 (Pinteraction = 0.004 and 0.01, respectively. In vitro, potassium enhanced the expression of Foxp3 in both naïve and memory CD4+ T cells via activating Smad2/3 and inhibiting Smad7 in TH17 cells. Conclusion:Dietary potassium is inversely associated with risk

Full Text Available This randomized, single-blind, parallel group study was conducted to compare omeprazole with ranitidine for the treatment of symptoms associated with gastroesophageal reflux disease (GERD, uncomplicated duodenal ulcer (DU or both. After baseline assessments, patients were randomized to receive daily treatment with either 20 mg omeprazole or 300 mg ranitidine for four weeks. In total, 1481 patients (1001 omeprazole, 480 ranitidine with a diagnosis of GERD (n=904 and/or DU (n=577, confirmed by endoscopy or barium meal and reporting moderate to severe symptoms, were included in the analyses. The seventy of overall daytime symptoms reported by the omeprazole group at clinic visits was lower than that reported by the ranitidine group at week 2 for the entire patient group (P=0.0002 and at both weeks 2 and 4 for the subgroup of patients with GERD (P=0.0001 and P=0.001, respectively. The severity of overall night-time symptoms reported by the omeprazole group was lower than that reported by the ranitidine group at week 4 for all patients as a whole (P=0.042 and at both weeks 2 and 4 for the subgroup of patients with GERD (P=0.035 and P=0.010, respectively. There were no significant differences in reports of adverse events. In the omeprazole group, 19% of patients at week 2 and 15% of patients at week 4 reported adverse events, while the corresponding results from the ranitidine group were 21% and 11%. In conclusion, patients with GERD, DU or both treated with omeprazole 20 mg daily for four weeks showed statistically significant reductions in symptoms compared with patients treated with ranitidine 300 mg daily for the same period of time. The percentage of patients with any remaining daytime symptoms was 12% lower in the omeprazole group compared with the ranitidine group at week 2, and 7% lower at week 4. Five per cent fewer patients in the omeprazole group experienced night-time symptoms at either week 2 or week 4.

Full Text Available Lupus Erythematosus (LE is a multi-organ auto-immune disease which results from complex interaction of genetic and environmental factors. The clinical spectrum ranges from minor cutaneous lesions to life threatening multi-organ dysfunction. The skin manifestations are variable and common and range from LE specific to LE non-specific cutaneous disease. Vasculitis is one of the most common non-specific skin lesion of Systemic lupus erythematosus (SLE and appears as purpuric lesions, infarcts along lateral nail folds, peripheral gangrene, sub-cutaneous nodules and ulcers. Mixed cryoglobulinaemia (type II is associated with connective tissue disorders including SLE. Skin manifestations are seen in 60-100% patients and are more common in females. The most common manifestation is palpable purpura of lower extremities seen in 30-100% which often is triggered in winter or on cold exposure. Skin infarction, hemorrhagic crusts and ulcers are seen in 25% of patients. Wide spread necrotic ulcers are seen in 10-25% of patients which are often exacerbated by cold.

Ulcerative Colitis (UC) together with Crohn's disease (CD) belongs to inflammatory bowel diseases (IBD). IBD is to date as frequent as Insulin Dependent Diabetes (IDDM) and is second to Rheumatoid Arthritis (RA) in its chronicity. The majority (91%) of patients with UC have a mild to moderate disease course eligible for 5-ASA treatment. Poor adherence in UC is a well known phenomenon, which is associated with a 5-fold increased risk of relapse and increased health care costs. Web-based treatment solution with self-initiated 5-ASA treatment in UC based on the patient's pattern recognition of the disease course had not been published previously. The aims of the thesis were: 1) In a European evidence based consensus to assess the IBD patients' need for Quality of Health Care (QoHC); 2) To validate the influence of a Patient Educational Center (PEC) and a web-based treatment solution program, www.constant-care.dk, on patients' disease self-management, adherence, Quality of Life, and disease course after 1 year of self-initiated 5-ASA treatment. UC patients in a conventional out-patient setting were used as controls; 3) To validate two new quantitative rapid tests (RT scanning and HT photo) for Faecal Calprotectin (FC) measurement, and to assess whether HT photo can be useful as a home test to help the patients deciding on self-initiated treatment. The ECCO Consensus found evidence for optimising QoHC by "information"; "education", "benchmarking", and "psychological analysis", which could help to improve patient compliance, QoL, and to decrease depression and anxiety. UC patients, educated in the PEC, significantly improved the level of disease specific knowledge. Patient education and training on www.constant-care.dk, being validated on first 21 Danish patients and subsequently on 233 Danish and 100 Irish patients, showed that the new web guided approach was feasible, safe, and cost effective for the selected group of the patients included in the trial.

Full Text Available We have examined the prevalence of gene cagA and vacA alleles in 129 patients, 69 with gastritis and 60 with peptic ulcer diseases from North Brazil and their relation with histopathological data. vacA and cagA genotype were determined by polymerase chain reaction. Hematoxylin-eosin staining was used for histological diagnosis. 96.6% of the patients were colonized by Helicobacter pylori strains harboring single vacA genotype (nont-mixed infection. Among them, 11.8% had subtype s1a, 67.8% had subtype s1b, and 17% subtype s2. In regard to the middle region analysis, m1 alleles were found in 75.4% and m2 in 21.2% of patients. The cagA gene was detected in 78% patients infected with H. pylori and was associated with the s1-m1 vacA genotype. The H. pylori strains, vacA s1b m1/cagA-positive, were associated with increased risk of peptic ulcer disease and higher amounts of lymphocytic and neutrophilic infiltrates and the presence of intestinal metaplasia. These findings show that cagA and vacA genotyping may have clinical relevance in Brazil.

We present a man with refractory leg ulcers, bilateral varicosis of the lower extremities, and Buerger disease. Autoimmune work-up was negative. However, chromosome analysis showed Klinefelter syndrome (48 XXY). Ulcerative lesions of the lower extremities are a complication of Klinefelter syndrome. To date, the pathogenesis of ulcers in Klinefelter syndrome has not been clarified, but several factors, such as abnormalities of fibrinolysis and prothrombotic states, might be involved. Our present case emphasizes the importance of considering Klinefelter syndrome in the differential diagnosis of a male patient with nonhealing ulcers of the lower extremities.

Full Text Available El síndrome de la úlcera rectal solitaria es una entidad benigna poco común cuyos síntomas más frecuentes son la rectorragia y el dolor anal. Los hallazgos anatomopatológicos son típicos. Se suele evidenciar engrosamiento de la mucosa, elongación y distorsión de las glándulas, una lámina propia edematosa con gran cantidad de colágena y engrosamiento de la muscularis mucosae. El diagnóstico se realiza mediante endoscopia con toma de biopsias. No siempre se trata de lesiones ulceradas. Se suele localizar preferentemente en la cara rectal anterior y/o lateral, aunque hasta un 30% de las lesiones son múltiples, existiendo casos de afectación del colon sigmoide y descendente. Por tanto, la presentación puede ser heterogénea y este es el motivo por el que esta entidad es también conocida como la "enfermedad de las tres mentiras". Presentamos un caso de síndrome de la ulcera rectal solitaria manifestado endoscópicamente como una placa eritematosa localizada en la cara lateral izquierda del recto.Solitary rectal ulcer syndrome is an uncommon benign condition characterized by rectal bleeding, passage of mucus, and pain. Histological features are well established as obliteration of the lamina propria by fibrosis and smooth-muscle fibers extending from a thickened muscularis mucosa to the lumen. Diagnosis can usually be made on sigmoidoscopy, and biopsies should always be taken. Ulceration is not universally present, and polypoid, non-ulcerated lesions and erythematous areas are also seen. The lesion or lesions are most often found on the anterior or anterolateral wall of the rectum, although they can also be located in the left colon and be more extensive or even circumferential. Lesions are multiple in 30 percent of cases. These are the reasons why this entity is also known as "the disease of three lies". We report a case of solitary rectal ulcer syndrome presenting at endoscopy with an erythematous area on the left side wall of the
近年来，老年患者消化性溃疡发病率呈现出上升趋势。且其在发病部位、病理学特征、临床症状及并发症等方面均具有区别于中青年患者的独特临床特点。全面理解老年人消化性溃疡临床特点，进行积极有效护理对老年人健康具有十分积极的意义。%In recent years, the incidence of the aged patients with peptic ulcer is on the rise in our country. Many aspects, such as pathogenic sites, pathological characteristics, clinical symptoms, and complications have unique characteristics which are different from young and middle-aged patients in this disease. Fully understanding the clinical characteristics of the aged patients with peptic ulcer correctly and developing positive and effective nursing are signiifcant for the health of the elderly.

Liver penetration is a rare but serious complication of peptic ulcer disease. Usually the diagnosis is made by operation or autopsy. Clinical and laboratory data were no specific. A 64-year-old man was admitted with upper gastrointestinal bleeding. Hepatic penetration was diagnosed as the cause of bleeding. Endoscopy showed a large gastric ulcer with a pseudotumoral mass protruding from the ulcer bed. Definitive diagnosis was established by endoscopic biopsies of the ulcer base.
Full Text Available Pressure ulcer in an otherwise sick patient is a matter of concern for the care givers as well as the medical personnel. A lot has been done to understand the disease process. So much so that USA and European countries have established advisory panels in their respective continents. Since the establishment of these organizations, the understanding of the pressure ulcer has improved significantly. The authors feel that the well documented and well publicized definition of pressure ulcer is somewhat lacking in the correct description of the disease process. Hence, a modified definition has been presented. This disease is here to stay. In the process of managing these ulcers the basic pathology needs to be understood well. Pressure ischemia is the main reason behind the occurrence of ulceration. Different extrinsic and intrinsic factors have been described in detail with review of literature. There are a large number of risk factors causing ulceration. The risk assessment scales have eluded the surgical literature and mostly remained in nursing books and websites. These scales have been reproduced for completion of the basics on decubitus ulcer. The classification of the pressure sores has been given in a comparative form to elucidate that most of the classifications are the same except for minor variations. The management of these ulcers is ever evolving but the age old saying of "prevention is better than cure" suits this condition the most.

Venous disease is the most common cause of chronic leg ulceration and represents an advanced clinical manifestation of venous insufficiency. Due to their frequency and chronicity, venous ulcers have a high socioeconomic impact, with treatment costs accounting for 1% of the health care budget in Western countries. The evaluation of patients with venous ulcers should include a thorough medical history for prior deep venous thrombosis, assessment for an hypercoagulable state, and a physical examination. Use of the CEAP (clinical, etiology, anatomy, pathophysiology) Classification System and the revised Venous Clinical Severity Scoring System is strongly recommended to characterize disease severity and assess response to treatment. This venous condition requires lifestyle modification, with affected individuals performing daily intervals of leg elevation to control edema; use of elastic compression garments; and moderate physical activity, such as walking wearing below-knee elastic stockings. Meticulous skin care, treatment of dermatitis, and prompt treatment of cellulitis are important aspects of medical management. The pharmacology of chronic venous insufficiency and venous ulcers include essentially two medications: pentoxifylline and phlebotropic agents. The micronized purified flavonoid fraction is an effective adjunct to compression therapy in patients with large, chronic ulceration.

Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician's believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for "surgical disease" or for "Sippy" diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

The current study examined the relationship between the Five-Factor Model personality traits and physician-confirmed peptic ulcer disease (PUD) diagnosis in a large population-based adult sample, controlling for the relevant behavioral and sociodemographic factors. Personality traits were assessed by participants themselves and by knowledgeable informants using the NEO Personality Inventory-3 (NEO PI-3). When controlling for age, sex, education, and cigarette smoking, only one of the five NEO PI-3 domain scales - higher Neuroticism - and two facet scales - lower A1: Trust and higher C1: Competence - made a small, yet significant contribution (p personality traits that are associated with the diagnosis of PUD at a particular point in time. Further prospective studies with a longitudinal design and multiple assessments would be needed to fully understand if the FFM personality traits serve as risk factors for the development of PUD.
Full Text Available Abstract Background Ulcerative colitis (UC and Crohn's disease (CD are characterized by intestinal inflammation mainly caused by a disturbance in the balance between cytokines and increased complement (C activation. Our aim was to evaluate possible associations between C activation capacity and prednisolone treatment. Methods Plasma from patients with exacerbations of UC (n = 18 or CD (n = 18 were collected before and during high dose prednisolone treatment (1 mg/kg body weight and tapering. Friedman's two way analysis of variance, Mann-Whitney U test and Wilcoxon signed-rank sum test were used Results Before treatment, plasma from CD patients showed significant elevations in all C-mediated analyses compared to the values obtained from 38 healthy controls (p Conclusion Our findings indicate that C activation capacity is up-regulated significantly in plasma from CD patients. The decreases observed after prednisolone treatment reflect a general down-regulation in immune activation.

Full Text Available Oral ulcers is a very common disorder of the oral mucosa. Patients with signs or symptoms of oral ulcers are sometimes referred to gastroenterology clinics, however, in most instances the ulcers does not reflect gastrointestinal disease, some with a chronic non- healing ulcer are advised biopsy. Indeed, a spectrum of disorders can give rise to oral mucosal ulcers ranging from minor local trauma to significant local disease such as malignancy or systemic illness. Lesions of the tongue have a broad differential diagnosis ranging from benign idiopathic processes to infections, cancers, and infiltrative disorders. This article will focus on common ulcerative disorders of the tongue in aspects of their clinical features and differential diagnosis, two case reports with the diagnosis and conservative management for long-term chronic ulcers. The two cases which are reported in this article had a differential diagnosis of Squamous cell carcinoma of the tongue. The clinical picture was craterlike lesion, having a velvety-red base and a rolled, indurated border and most important painless in both cases. Removal of the irritant which was the tooth, rehabilitation of the oral mucosa by lubrication with Cocus Nucifera resulted in the healing of the ulcers. Functional components of Cocus Nucifera are Squaline, tocopherol, phytosterols and other sterols which are all plant steroids.

Genetic studies have implicated MYO9B, which encodes myosin IXb (Myo9b), a motor protein with a Rho GTPase activating domain (RhoGAP), as a susceptibility gene for inflammatory bowel disease (IBD). Moreover, we have recently shown that knockdown of Myo9b in an intestinal epithelial cell line impairs wound healing and barrier function. Here, we investigated whether mice lacking Myo9b have impaired intestinal barrier function and features of IBD. Myo9b knock out (KO) mice exhibit impaired weight gain and fecal occult blood (indicator of gastrointestinal bleeding), and increased intestinal epithelial cell apoptosis could be detected along the entire intestinal axis. Histologic analysis revealed intestinal mucosal damage, most consistently observed in the ileum, which included superficial ulceration and neutrophil infiltration. Focal lesions contained neutrophils and ultrastructural examination confirmed epithelial discontinuity and the deposition of extracellular matrix. We also observed impaired mucosal barrier function in KO mice. Transepithelial electrical resistance of KO ileum is >3 fold less than WT ileum. The intestinal mucosa is also permeable to high molecular weight dextran, presumably due to the presence of mucosal surface ulcerations. There is loss of tight junction-associated ZO-1, decreased lateral membrane associated E-cadherin, and loss of terminal web associated cytokeratin filaments. Consistent with increased Rho activity in the KO, there is increased subapical expression of activated myosin II (Myo2) based on localization of phosphorylated Myo2 regulatory light chain. Except for a delay in disease onset in the KO, no difference in dextran sulfate sodium-induced colitis and lethality was observed between wild-type and Myo9b KO mice.

Diabetic foot ulceration represents a major medical, social and economic problem all over the world. While more than 5% of diabetic patients have a history of foot ulceration, the cumulative lifetime incidence may be as high as 15%. Ethnic differences exist in both ulcer and amputation incidences. Foot ulceration results from the interaction of several contributory factors, the most important of which is neuropathy. The use of the total-contact cast is demonstrated in the treatment of plantar neuropathic ulcers. Histological evidence suggests that pressure relief results in chronic foot ulcers changing their morphological appearance by displaying some features of an acute wound. Thus, repetitive stresses on the insensate foot appear to play a major role in maintaining ulcer chronicity. It is hoped that research activity in foot disease will ultimately result in fewer ulcers and less amputation in diabetes.

Full Text Available Os sintomas articulares constituem a manifestação extra-intestinal mais comum em pacientes com doença de Crohn e com retocolite ulcerativa. Reconhecida como artrite colítica, e mais recentemente, artrite enteropática, está classificada como uma das doenças do grupo das espondiloartropatias. Reconhecidamente, há dois padrões de acometimento articular: 1 periférico, habitualmente, associado aos períodos de atividade da doença intestinal e sem associação com o antígeno HLA B27, e 2 axial, caracterizado por espondilite e sacroiliíte, com curso clínico e radiográfico independente da doença intestinal e associado ao HLA B27.Joint involvement is the most commom extraintestinal manifestation in patients with Crohn's disease and ulcerative colitis. The colitic arthritis, lately called enteropathic arthritis, is classified as one of the diseases of the spondyloarthropathies group. There are two patterns of joint involvement: 1 peripheral arthritis, usually coincides with exacerbations of the inflammatory bowel disease and is not associated with the HLA B27 antigen; and 2 axial involvement, characterized by spondylitis and sacroiliitis, which the clinical course is independent of the intestinal disease, and has an association with HLA B27.

Full Text Available Marjolin's ulcer is rare and aggressive cutaneous malignancy that develops in previously traumatized or chronically inflamed skin. We present the case of a 43-year-old white man suffering from an exophytic bleeding ulcerated lesion on the distal third of the left leg where he already had a large scar from a compound fracture of the tibia and fibula complicated with chronic osteomyelitis. Surgical excision and biopsy were performed, showing a squamous cell carcinoma consistent with Marjolin's ulcer. We decided to present this case given the rare occurrence of the disease. We concluded that patients with this type of lesion should be subject to periodic examinations to prevent or treat potential recurrences.
Full Text Available An 18-year-old male presented with a nonhealing wound on left lower limb, pain and swelling over multiple joints, weight loss, and yellowish discoloration of eyes and urine for the past 4 years. On examination, the patient had pallor, icterus, and generalized lymphadenopathy with a nonhealing unhealthy ulcer over left medial malleolus. He had deformed joints with hepatomegaly and splenomegaly. His laboratory investigations were positive for antinuclear antibody (ANA and anticardiolipin antibody (ACLA. Synovial fluid analysis showed inflammatory findings. Biopsy of margin of the ulcer showed findings consistent with Acroangiodermatitis of Mali. The patient was treated with disease-modifying antirheumatic drugs (DMARDs and aspirin for juvenile idiopathic arthritis and secondary antiphospholipid antibody syndrome (APS, respectively. The ulcer was managed conservatively with systemic antibiotics and topical steroids along with limb elevation and compression elastic stockings. The patient's symptoms improved significantly, and he is in our followup.
This study analyzes data on peptic ulcer disease based on deaths for 1951-1988 and hospital separations for 1969-1988. The source of the data are mortality and morbidity statistics provided to Statistics Canada by the provinces. The age-standardized mortality rates (ASMR) for peptic ulcer disease decreased from 1951 to 1988 by 69.4% for men (8.5 to 2.6 per 100,000 population), and 31.8% for women (2.2 to 1.5). Separation rates from hospitals during 1969-1988 for peptic ulcer disease also decreased by 59.8% for men (242.7 to 97.6 per 100,000 population) and 35.6% for women (103.2 to 66.5). Age-specific rates for both mortality and hospital separations increased with age. Epidemiological studies indicate that the incidence of peptic ulcer disease is declining in the general population. The downward trends in mortality and hospitalization rates for peptic ulcer disease reflect this change in incidence, but additional factors probably contribute as well to this decline. Male rates for both mortality and hospital separations were much higher than female rates at the beginning of the study period; but toward the end, the gap between the sexes narrowed considerably, mainly because the male rates declined substantially while the female rates decline moderately. The slower decline in the rates for women may be related to such factors as the increasing labour force participation among women and the slower decline in the population of female smokers.

Full Text Available BACKGROUND: Randomized trials show that male circumcision (MC reduces the incidence of HIV and herpes simplex virus type 2 (HSV-2 infections, and symptomatic genital ulcer disease (GUD. We assessed the role of GUD and HSV-2 in the protection against HIV afforded by MC. METHODS AND FINDINGS: HIV-uninfected men were randomized to immediate (n = 2,756 or delayed MC (n = 2,775 in two randomized trials in Rakai, Uganda. GUD symptoms, HSV-2 status, and HIV acquisition were determined at enrollment and at 6, 12, and 24 mo of follow up. Ulcer etiology was assessed by PCR. We estimated the prevalence and prevalence risk ratios (PRRs of GUD in circumcised versus uncircumcised men and assessed the effects of HSV-2 serostatus as a risk-modifying factor for GUD. We estimated the proportion of the effect of MC on HIV acquisition that was mediated by symptomatic GUD, and by HSV-2 infection. Circumcision significantly reduced symptomatic GUD in HSV-2-seronegative men (PRR = 0.51, 95% [confidence interval] CI 0.43-0.74, HSV-2-seropositive men (PRR = 0.66, 95% CI 0.51-0.69, and in HSV-2 seroconverters (PRR = 0.48, 95% CI 0.30-0.79. The proportion of acute ulcers due to HSV-2 detected by PCR was 48.0% in circumcised men and 39.3% in uncircumcised men (chi(2p = 0.62. Circumcision reduced the risk of HIV acquisition in HSV-2 seronegative men (incidence rate ratio [IRR] = 0.34, 95% CI 0.15-0.81, and potentially in HSV-2 seroconverters (IRR = 0.56, 95% CI 0.19-1.57; not significant, but not in men with prevalent HSV-2 at enrollment (IRR = 0.89, 95% CI 0.49-1.60. The proportion of reduced HIV acquisition in circumcised men mediated by reductions in symptomatic GUD was 11.2% (95% CI 5.0-38.0, and the proportion mediated by reduced HSV-2 incidence was 8.6% (95% CI -1.2 to 77.1. CONCLUSIONS: Circumcision reduced GUD irrespective of HSV-2 status, but this reduction played only a modest role in the protective effect of circumcision on HIV acquisition.

@@ Ulcer of the stomach and duodenum,also called ulcerative disease,is a sharply circumscribed loss of the tissue lining those parts of the digestive tract exposed to gastric juice containing acid and pepsin. Because its formation and development are closely related to the digestive effect of acidic gastric juice and pepsase,the disease is called peptic ulcer. It is a common disease,belonging to epigastric pain in TCM,mainly caused by cold attacking the stomach,stagnated liver-qi affecting the stomach,or spleen and stomach deficiency with deficiency and cold of the middle-jiao. Regulating qi to stop pain is the principle for its treatment. Peptic ulcer is usually differentiated as the following TCM syndromes.

AIM: To investigate the influence of fish oil enriched enteral diet on intestinal tissues taken from Crohn's disease (CD), ulcerative colitis (UC) and non-inflamed non-IBD control patients in vitro.METHODS: Colonoscopic biopsies from patients with active CD (n = 4), active UC (n = 7), and non-inflamed non-IBD control patients (n = 4) were incubated (three dilutions of 1:20, 1:10, and 1:5) with Waymouth's culture medium and enteral elemental diet (EO28, SHS, Liverpool, UK) modified in the fatty acid composition with fish oil (EF) in an organ culture system for 24 h. In each experimental set-up, incubation with Waymouth's medium alone as control was included. Tissue viability was assessed by adding bromodeoxyuridine (BrdU) to the culture fluid and immunohistochemically staining for BrdU uptake. Cytokine ratio of IL-1ra/IL-1β (low ratio indicative of inflammation) and production of those cytokines as a percentage of medium control were assayed in the culture supernatant. RESULTS: Incubation of CD-affected tissue with EF (1:20, 1:10, and 1:5) modestly and non-significantly increased IL-1ra/IL-1β ratio as compared with medium control (CD 39.1±16.1; 26.5±7.8, 47.1±16.8 vs control 13.0±2.2), but incubation of UC-affected tissues increased IL-1ra/IL-1β ratio significantly in all three dilutions (UC 69.1±32.2, P＜0.05; 76.1±36.4, P = 0.05;84.5±37.3, P＜0.02; vs control 10.2±3.7). Incubation of non-inflamed non-IBD control tissue did not increase the IL-1ra/IL-1β ratio in any dilution compared to medium control (69.3±47.0, 54.1±30.6, 79.4±34.0 vs control 76.1±37.3). Average percentage production of IL-1β indexed against medium control was significantly less in UC after EF incubation as compared with CD (UC 24.0±4.8 vs CD 51.8±8.1; P＜0.05). Average percentage production of IL-1ra was markedly higher in UC (135.9±3.4) than that in control patients (36.5±4.3) (P＜0.0001).CONCLUSION: IBD tissues, after incubation with elemental diet modified in its
Full Text Available Introduction Peptic ulcer perforation is a complication of ulcer disease which requires urgent surgical treatment. The aim of this paper was to point out our experience in surgical treatment of perforated peptic ulcer. Material and methods This retrospective study analyzes results of surgical treatment in 365 patients with perforated peptic ulcer during the period January 1996 to December 2000. Results During the last 5-year period 365 patients were treated following peptic ulcer perforation. The average age was 43.53±8.26, with the span from 18 to 86. The most frequent surgical procedures in treatment of peptic ulcer perforation were: simple closure with biopsy (55.88%, excision of the ulcer with a pyloroplasty and vagotomy (35.29% as nonresection surgical procedures and stomach resection after Billroth II (8.83%. The postoperative mortality was 4.41%. Conclusions The methods of choice in surgical treatment of gastric ulcer perforation are nonresection surgical procedures with drug therapy and eradication of Helicobacter pylori, if present.

Background Gene expression alterations are associated with disease behavior in inflammatory bowel disease (IBD). microRNAs (miRNAs) are dominant in the regulation of gene expression, and may affect IBD phenotype. Our aim was to assess mucosal miRNA expression in IBD and the correlation with intestinal inflammation. Methods We performed a large-scale analysis of ileal mucosal miRNA. Biopsies were retrieved from patients with ileal Crohn’s disease (CD), unoperated ulcerative colitis (UC) patients, UC patients after pouch surgery, and normal controls (NC). Pouch UC patients were classified as having a normal pouch (NP), chronic pouchitis (CP), and Crohn’s-like disease of the pouch (CLDP). miRNA expression was analyzed by parallel massive (next-generation) sequencing (NGS). Bioinformatics tools were applied for clustering and the detection of potential targets. Results Sixty-one subjects were recruited. The ileum of unoperated UC patients was comparable with NC. There were significant miRNA expression alterations (fold change ≥2, corrected P ≤.05) in NP (n = 6), CP (n = 40) and CLDP (n = 139), but only two expression alterations were noted in CD. More than 90% of the altered miRNAs were up-regulated, and many were predicted to be associated with significantly decreased transcripts. miRNAs alterations were generally clustered with disease phenotypes. Conclusions Ileal inflammation causes increased miRNA expression. miRNA alterations correlate with IBD phenotype, apparently by controlling the down-regulation of specific mRNAs. PMID:27536783

One of the most likely causes of the lack of effectiveness of eradication therapy of peptic ulcer associated with Helicobacter pylori, is a feature of omeprazole metabolism by cytochrome CYP2C19. The paper work presents evidence that the rate of reduction of the clinical picture and the likelihood of scarring ulcers and eradication rates higher in patients slow metabolizers of omeprazole.
Full Text Available The aim of this study was to investigate the 1-year period prevalence of oral aphthous ulcers (OAUs and their association with oral health-related quality of life (OHQOL in patients with Behçet’s disease (BD and in the general population. In this cross-sectional study, 675 patients with Behçet’s disease (BD group and 1,097 males and females in the Japanese general population (control group completed both questionnaires on their OAU status during the prior year and the General Oral Health Assessment Index (GOHAI. In the BD group, 84% of patients reported experiencing an OAU during the previous year, and the mean number of OAUs/year was 13. In the control group, 31% of individuals experienced an OAU during the previous year, and the mean number of OAUs/year was one. Multivariate analysis indicated that both BD patients (OR, 6.2; 95% CI, 4.8–8.0 and controls (OR, 2.6; 95% CI, 2.0–3.5 who had OAUs at least twice per year were more likely to have GOHAI scores below the norm than were controls who had fewer than two OAUs per year. The association between HLA-B*51 and OAUs remains unknown. The presence of OAUs has a negative effect on the OHQOL of patients with BD.

Buruli ulcer (BU) is an emerging, but neglected tropical disease, where there has been a reported association with disturbed aquatic habitats and proposed aquatic macroinvertebrate vectors such as biting Hemiptera. An initial step in understanding the potential role of macroinvertebrates in the ecology of BU is to better understand the entire community, not just one or two taxa, in relation to the pathogen, Mycobacterium ulcerans, at a large spatial scale. For the first time at a country-wide scale this research documents that M. ulcerans was frequently detected from environmental samples taken from BU endemic regions, but was not present in 30 waterbodies of a non-endemic region. There were significant differences in macroinvertebrate community structure and identified potential indicator taxa in relation to pathogen presence. These results suggest that specific macroinvertebrate taxa or functional metrics may potentially be used as aquatic biological indicators of M. ulcerans. Developing ecological indicators of this pathogen is a first step for understanding the disease ecology of BU and should assist future studies of transmission.

Peptic ulcer bleeding is one of the most common emergency situations in medicine. Combined pharmacological and endoscopic therapy together with emerging interventional radiological procedures are successfully treating peptic ulcer disease, reserving surgical procedures for only a small portion of patients unresponsive to 'conventional' therapy. Technological advancement has seen a great improvement in the field of endoscopic treatment in the form of various methods of hemostasis. However, pharmacological therapy with proton pump inhibitors still plays the central role in the peptic ulcer bleeding treatment algorithm.
Peptic gastroduodenal ulcer disease results from an imbalance of acid secretion and mucosal defenses that resist acid digestion. Following developments in the medical treatment of peptic ulcer disease (PUD) in the last two decades, surgical intervention is currently confined to the treatment of complicated disease, namely, ulcer hemorrhage, perforation, penetration and obstruction. Simple closure or omental patch repair is the mainstay of treatment of perforated peptic ulcer (PPU), definitive...
Full Text Available Perforated peptic ulcer (PPU, despite antiulcer medication and Helicobacter eradication, is still the most common indication for emergency gastric surgery associated with high morbidity and mortality. Perforated peptic ulcer is a common abdominal disease that is treated by surgery. The development of laparoscopic surgery has changed the way to treat such abdominal surgical emergencies but there is no consensus on whether the benefits of laparoscopic closure of perforated peptic ulcer outweigh the disadvantages such as prolonged surgery time and greater expense. However we can say that laparoscopic repair is a viable and safe surgical option for patients with perforated peptic ulcer disease and should be considered with the necessary expertise available.

Corneal Ulcer is a deepithelization of the cornea and it is a very common disease in agricultural countries. The clinician most used parameter in order to identify a favorable ulcer evolution is the regress of the affected area. However, this kind of evaluation is subjective, once just the horizontal and vertical axes are measured based on a graduated scale and the affected area is estimated. Also, the registration of the disease is made by photographs. In order to overcome the subjectiveness and to register the images in a more accessible way (hard disks, floppy disks, etc.), we have developed an automatic system in order to evaluate the affected area (the ulcer). An optical system is implemented in a Slit Lamp (SL) and connected to a CCD detector. The image is displayed in PC monitor by a commercial frame grabber and a dedicated software for determining the area of the ulcer (precision of 20 mm) has been developed.

A national survey of investigators caring for human immunodeficiency virus (HIV)-infected women was undertaken to describe the clinical presentation of idiopathic genital ulcer disease. Patients with negative syphilis and herpes simplex testing and/or negative genital ulcer biopsy were included in this study. Study participants (n = 29) were generally severely immunocompromised (median CD4 cell count was 50/mm3, and 68% had an acquired immunodeficiency syndrome [AIDS]-defining opportunistic process). Thirty-seven percent had coexistent oral ulcers and 19% had their genital ulcer progress to fistula formation (four rectovaginal and one vaginal-perineal). There was generally a favorable response to topical, systemic, and intralesional steroid treatment. This study suggests that idiopathic or probable aphthous genital ulcers in women have similar clinical characteristics to aphthous oroesophageal ulcers. Although infrequent, these genital ulcers can cause severe morbidity. Further research is warranted to better define the pathophysiology and optimal management.

Full Text Available Objective. To study actovegin efficacy in the treatment of chronic skin ulcers due to ulceration of tophuses in pts with chronic tophaceous gout. Materials and methods. 6 pts with chronic tophaceous gout aged 52 to 77 years with disease duration from 6 to 20 years with longstanding persisting skin ulcers due to tophuses ulceration were included. In addition to allopuri- nol, steroid and nonsteroidal anti-inflammatory drugs they were treated with actovegin 20% intravenously and local applications of 2% actovegin gel. Clinical examination was performed before and after the course of therapy- Results. Two from six pts showed healing of single chronic ulcers to the end of the treatment course. In the remaining pts ulcer count and size decrease was achieved. Conclusion. Actovegin administration in combined therapy of chronic skin ulcers in pts with chronic tophaceous gout promoted healing of the defects in all cases.

possibly attributed to small bowel ulcers, nevertheless 30-d mortality was zero. Presence of chronic obstructive lung disease and diabetes was related with unexplained recurrence of hemorrhage in logistic regression analysis, while absence of small bowel ulcers was protective(relative risk 0.13, P = 0.05).CONCLUSION: Among NSAID consumers, more bleeders than non-bleeders with peptic ulcers present small bowel ulcers; lesions related to more severe bleeding and unexplained episodes of bleeding recurrence.

The revised guideline of 2013 is an update of the 2005 guideline "venous leg ulcer". In this special project four separate guidelines (venous leg ulcer, varicose veins, compression therapy and deep venous disorders) were revised and developed simultaneously. A meeting was held including representatives of any organisation involved in venous disease management including patient organizations and health insurance companies. Eighteen clinical questions where defined, and a new strategy was used to accelerate the process. This resulted in two new and two revised guidelines within one year. The guideline committee advises use of the C of the CEAP classification as well as the Venous Clinical Severity Score (VCSS) and a Quality of life (QoL) score in the assessment of clinical signs. These can provide insight into the burden of disease and the effects of treatment as experienced by the patient. A duplex ultrasound should be performed in every patient to establish the underlying aetiology and to evaluate the need for treatment (which is discussed in a separate guideline). The use of the TIME model for describing venous ulcers is recommended. There is no evidence for antiseptic or antibiotic wound care products except for a Cochrane review in which some evidence is presented for cadexomer iodine. Signs of infection are the main reason for the use of oral antibiotics. When the ulcer fails to heal the use of oral aspirin and pentoxifylline can be considered as an adjunct. For the individual patient, the following aspects should be considered: the appearance of the ulcer (amount of exudate) according to the TIME model, the influence of wound care products on moisturising the wound, frequency of changing compression bandages, pain and allergies. The cost of the dressings should also be considered. Education and training of patients t improves compliance with compression therapy but does not influence wound healing rates.

Ulcerative colitis (UC) is a chronic disease featuring recurrent inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complications of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed. This article is intended to give a general, practice- orientated overview of the key issues in ulcerative colitis treatment. Recommendations are based on published consensus guidelines derived from national and international guidelines on the treatment of ulcerative colitis.

Ulcerative colitis is a chronic inflammatory disease, characterized by diffuse mucosal inflammation in the colon. Adalimumab, as a TNF-α blocker, offers a safe and efficacious treatment option for patients with moderate to severe ulcerative colitis and refractory or intolerant to conventional medications; however, its cost-effectiveness profile has not yet been well established. Future economic evaluations should choose appropriate comparators in the context of target-reimbursement decision making and focus on cost-effectiveness over a long time horizon.
Full Text Available A prospective clinical study on choleakinesia following total vagectomy (Bilateral truncal vagotomy was carried out during the period from April 2005 to December 2010.Total 55 cases were studied who was suffering from chronic duodenal ulcer. Out of these total 55 cases fifteen cases had gastric outlet obstruction with hugely dilated stomach which was considered as control group in this study. Other 40 cases were considered as study group. Truncal vagotomy with retr ocolic isoperistaltic GJA done in study group and only retrocolic isoperistaltic GJA operation done in control group. Two patients had incomplete vagotomy. All the patients were male and average age was 38.1 years. 32.7% cases were belonging to the age gro up between 26 - 35 years which was the highest. Though the cases were operated till September 2010, they were followed up till December 2013. Gastric acidity, oral cholecystography and ultrasonography of upper abdomen was done in both pre and post - operative period. All cases were meticulously examined to exclude other associated pathology. Cases were diagnosed by Barium meal and clinical analysis.14days post - operatively gastric acid analysis and three months post - operatively oral cholecystography was done. In the post - operative follow up period ultrasonography upper abdomen was done. 39(71% patients were turned up for checkup in post - operative period out of which 29 patients belong to complete vagotomy group. In conclusion it was seen that following total vag otomy the contraction of gall bladder was definitely reduced with decrease % loss of bile results stasis of bile. There was more than double dilatation of the gall bladder as detected three months post - operatively  after complete section of vagus. 7.5% o f patients of complete vagotomy group developed gall stones till three to four years post - operatively and 20% patients developed minimal gall bladder sludge and 5% patients developed dense peripheral sludge
Full Text Available Ulcerative colitis (UC is a chronic idiopathic inflammatory disorder of colon. Frequency of UC is gradually increasing over few years worldwide. Prevalence is 35 to 100/100 000 people in USA, 1% of them are infants. UC develops in a genetically predisposed individual with altered intestinal immune response. An eight-month-old girl presented with loose bloody stool, growth failure, and moderate pallor. The girl was diagnosed as a case of UC by colonoscopy and biopsy. Treatment was thereafter started with immunosuppressive drugs. After initial induction therapy with parenteral steroid and infliximab, the patient is now on remission with azathioprine and mesalamine. UC is rare in Bangladesh, especially in children, and it is rarer during infancy. Several conditions like infective colitis, allergic colitis, Meckel′s diverticulitis, Crohn′s disease, etc. may mimic the features of UC. So, if a child presents with recurrent bloody diarrhea, UC should be considered as differential diagnosis.

Full Text Available BACKGROUND: Since 2004, treatment of Mycobacterium ulcerans disease, or Buruli ulcer, has shifted from surgery to daily treatment with streptomycin (STR + rifampin (RIF for 8 weeks. For shortening treatment duration, we tested the potential of daily rifapentine (RPT, a long-acting rifamycin derivative, as a substitute for RIF. METHODOLOGY/PRINCIPAL FINDINGS: BALB/c mice were infected with M. ulcerans in the right hind footpad and treated either daily (7/7 with STR+RIF or five days/week (5/7 with STR+RIF or STR+RPT for 4 weeks, beginning 28 days after infection when CFU counts were 4.88±0.51. The relative efficacy of the drug treatments was compared by footpad CFU counts during treatment and median time to footpad swelling after treatment cessation as measure of sterilizing activity. All drug treatments were bactericidal. After 1 week of treatment, the decline in CFU counts was significantly greater in treated mice but not different between the three treated groups. After 2 weeks of treatment, the decline in CFU was greater in mice treated with STR+RPT 5/7 than in mice treated with STR+RIF 7/7 and STR+RIF 5/7. After 3 and 4 weeks of treatment, CFU counts were nil in mice treated with STR+RPT and reduced by more than 3 and 4 logs in mice treated with STR+RIF 5/7 and STR+RIF 7/7, respectively. In sharp contrast to the bactericidal activity, the sterilizing activity was not different between all drug regimens although it was in proportion to the treatment duration. CONCLUSIONS/SIGNIFICANCE: The better bactericidal activity of daily STR+RIF and especially of STR+RPT did not translate into better prevention of relapse, possibly because relapse-freecure after treatment of Buruli ulcer is more related to the reversal of mycolactone-induced local immunodeficiency by drug treatment rather than to the bactericidal potency of drugs.

There is a close relationship between the human host and the intestinal microbiota, which is an assortment of microorganisms, protecting the intestine against colonization by exogenous pathogens. Moreover, the intestinal microbiota play a critical role in providing nutrition and the modulation of host immune homeostasis. Recent reports indicate that some strains of intestinal bacteria are responsible for intestinal ulceration and chronic inflammation in inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD). Understanding the interaction of the intestinal microbiota with pathogens and the human host might provide new strategies treating patients with IBD. This review focuses on the important role that the intestinal microbiota plays in maintaining innate immunity in the pathogenesis and etiology of UC and discusses new antibiotic therapies targeting the intestinal microbiota.

Pediatric ulcerative colitis (UC) shares many features with adult-onset disease but there are some unique considerations; therefore, therapeutic approaches have to be adapted to these particular needs. We aimed to formulate guidelines for managing UC in children based on a systematic review (SR......) of the literature and a robust consensus process. The present article is a product of a joint effort of the European Crohn's and Colitis Organization (ECCO) and the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN)....

Between 1986 and 1989, in 5 departments of Senegal, 436 new cases of leprosy were detected, of whom 225 were put under dapsone monotherapy and 211 under multidrug therapy (MDT). Of them, 190 could be followed-up during 2 years by means of annual bacteriological and clinical examination, including neurological assessment. In 2 years, the onset of 10 (5.3%) chronic plantar ulcers (CPU) was observed: 4 (4%) among the 99 patients under dapsone monotherapy and 6 (6.6%) among the 91 under MDT (no significant difference). Of the 10 CPU, 3 (2%) appeared among the 149 patients without any disability at detection while 7 (17%) were observed among the 41 others who presented a grade 1 disability at detection (p < 0.01). Of the 6 CPU appeared in the patients under MDT, 5 (22%) were observed among the 23 who presented a grade 1 disability at detection and 1 (1.5%) among the 68 who did not (p < 0.01). This difference was not noted in the patients under dapsone monotherapy. Our results need to be confirmed by other studies including a higher number of patients followed-up during a longer period of time. Nevertheless, they suggest that MDT could prevent the onset of CPU, but only in patients without any disability at detection. Therefore, they reemphasize the importance of early detection of the disease in leprosy control programmes.
I investigated changes of faecal short-chain fatty acids (SCFA) in 52 hospitalized patients with ulcerative colitis (UC) who had bloody diarrhoea (severe and moderate colitis). The results suggest that molar ratios of faecal lactate could be helpful to monitor the disease activity of UC patients. Faecal SCFA output correlated directly with faecal output. This finding reflected an increase in output of lactate and acetate. In severe colitis, concentrations of faecal lactate were increased, whereas those of faecal major components of SCFA (acetate, propionate and n-buty-rate) were markedly reduced. Further, faecal lactate concentrations were increased in cases with bloody diarrhoea and reduced in those with formed stool. Patients were divided into two groups according with their treatments: patients treated with total parenteral nutrition (TPN) or low-residue UC diet. The molar ratio of faecal lactate in the TPN group was reduced below 2% in four weeks, whereas that in the UC diet group was reduced into the 2% mark in eight weeks. These findings support that patients in the former group were more rapidly induced into remission.
Between September 1986 and February 1988, a case-control study involving 27 Italian dermatological centers collaborating in the Gruppo Italiano Studi Epidemiologici in Dermatologia was conducted, concerning the relationship between history of several medical conditions and exposures to drugs and the risk of lichen planus. The cases were all consecutive patients with a new diagnosis of lichen planus, and the controls were patients under dermatological care observed under the same conditions. A total of 711 cases and 1395 controls met the admission criteria and were interviewed by trained investigators. Patients with histories of alopecia areata were found to be at risk for lichen planus (relative risk = 2.7; 95% confidence interval, 1.1 to 6.5). Five patients (0.7%) in the group with lichen planus had a history of ulcerative colitis, while none of the controls had this disease. The risk of lichen planus was also increased in patients with a history of chronic active hepatitis, but this increase was not statistically significant (relative risk = 4.7; 95% confidence interval, 0.7 to 29.4).

Sleep is integral to life and sleep duration is important in sleep quality, physical, and psychological health. Disturbances in sleep duration have been associated with increased risk of metabolic disorders, hypertension, and overall mortality. Sleep disturbance has also been linked with various gastrointestinal disorders. However, the association between sleep and peptic ulcer disease (PUD) has not been evaluated. We investigated the association between sleep duration and PUD. Subjects were included from the fifth Korean National Health and Nutrition Examination Survey conducted from 2008–2009. Individuals with PUD were defined as those with a physician diagnosis of PUD. Daily sleep duration was established by asking participants the amount of time that they slept per day. Multiple logistic regression models were used to evaluate the association of PUD and sleep duration. This study included 14,290 participants (8,209 women). The prevalence of PUD was 5.7% and was higher in men (6.8%) than in women (4.9%). Women who slept ≥9 hours were significantly less likely to have PUD compared to women who slept 7 hours. In men, longer sleep duration (≥9 hours) had a tendency toward PUD prevention. Our results suggest that longer sleep duration may play a protective role for PUD development. PMID:27830741

BACKGROUND AND AIMS: A hallmark of inflammatory bowel disease [IBD] is chronic inflammation, which leads to excessive extracellular matrix [ECM] remodelling and release of specific protein fragments, called neoepitopes. We speculated that the biomarker profile panel for ulcerative colitis [UC......-degraded vimentin [VICM] were studied with a competitive ELISA assay system in a cohort including 164 subjects [CD n = 72, UC n = 60, and non-IBD controls n = 32] and a validation cohort of 61 subjects [CD n = 46, and UC n = 15]. Receiver operating characteristic curve analysis and logistic regression modelling....... Furthermore, the biomarkers C1M [AUC = 0.81], C3M [AUC = 0.83], VICM [AUC = 0.83], and P1NP [AUC = 0.77] were best to differentiate UC from non-IBD. The best combinations of biomarkers to differentiate CD from UC and UC from non-IBD were VICM, C3M, C4M [AUC = 0.90] and VICM, C3M [AUC = 0.98] respectively...

Background: Brain tumors, traumatic head injury, and other intracranial processes including infections, can cause increased intracranial pressure and lead to overstimulation of the vagus nerve. As a result, increased secretion of gastric acid may occur which leads to gastro-duodenal ulcer formation known as Cushing's ulcer. Methods: A review of original records of Dr. Harvey Cushing's patients suffering from gastro-duodenal ulcers was performed followed by a discussion of the available litera...

Gastric ulcer is one of the most common chronic gastrointestinal diseases characterized by a significant defect in the mucosal barrier. Helicobacter pylori (H. pylori) infection and the frequent long-term use of non-steroidal anti-inflammatory drugs are major factors involved in gastric ulcer development. Acid inhibitors and antibiotics are commonly used to treat gastric ulcer. However, in the last few decades, the accumulating evidence for resistance to antibiotics and the side effects of an...

Mooren′s ulcer is strictly a peripheral ulcerative keratitis (PUK) with no associated scleritis. It occurs completely in absence of any diagnosable systemic disorder that could be responsible for the progressive destruction of the cornea. The aetiology of Mooren′s ulcer remains uncertain. However, recent studies indicate that it is an autoimmune disease directed against a specific target molecule in the corneal stroma, probably triggered in genetically susceptible individuals by...

Full Text Available Objectives To review some aspects of the etiopathogenesis of peptic ulcerous disease especially on the basis of studies on its correlation with Helicobacter pylori (H. pylori. Methods A search was made in the data bases MEDLINE, LILACS and PubMed, and in Brazilian and foreign books, referring to the incidence and prevalence of infection by H. pylori and of peptic ulcerous disease in various populations of different countries. Results It was observed that the prevalence of H. pylori infection is similar in individuals with peptic ulcerous disease and the general population. There are differences between countries with respect to the prevalence of infection and of gastric or duodenal peptic ulcers. In many countries the prevalence of infection by H. pylori shows stability while the prevalence of peptic ulcerous disease is declining. The prevalence of peptic ulcerous disease without H. pylori infection varies between 20% and 56% in occidental countries. Discussion The observations might be suggestive of H. pylori being only one more factor to be summed together with other aggressive components in the genesis of peptic ulcerous disease. We would therewith be returning to the classic concept that peptic gastric and duodenal ulcers have multifactorial etiology and would result from imbalance between aggressive and defensive factors. The focus of studies should be enriched with the identification of the defensive factors and of other aggressive factors besides the well known H. pylori and non-steroidal anti-inflammatory drugs, since these two aggressors do not exhaust the full causal spectrum.

An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.
Full Text Available Medical therapy in patients with inflammatory bowel disease (IBD has specific objectives that need to be remembered when considering any form of intervention. These objectives include to improve the quality of life, to improve symptoms, to improve nutrition and reduce the risk of nutritional deficiencies, to reduce the frequency and severity of recurrences, to reduce complications, including the need for surgery, and to cure the disease. Medical therapy potentially helps to achieve all of these objectives for sufferers of IBD, except the last one – until the pathogenesis of the recurrent or continuous episodes of bowel inflammation is better understood, this last objective will remain "a riddle, wrapped in a mystery, inside an enigma".

A 19-year-old Japanese man had been treated for ulcerative colitis for 2 years. He was admitted to our hospital with nodulocystic inflammatory papules and pustules on his face and chest, high-grade fever, arthralgia and general malaise. A biopsy specimen from a pustule showed prominent infiltration of neutrophils in the epidermis and dermis, particularly around hair follicles. We made a diagnosis of acne fulminans. The systemic administration of prednisolone at 30 mg daily for 1 week immediately improved his skin lesions and other symptoms; however, during tapering of prednisolone at 20 mg daily, skin lesions flared up. The addition of oral diaminodiphenylsulfone improved the skin lesions. Although there have been a few reports of acne fulminans associated with Crohn's disease, this is the first case report of acne fulminans in a patient with ulcerative colitis. It is noteworthy that the addition of diaminodiphenylsulfone was effective for treating the relapse of acne fulminans in this case.
When treating diabetic foot ulcers it is important to be aware of the natural history of the diabetic foot, which can be divided into five stages: stage 1, a normal foot; stage 2, a high risk foot; stage 3, an ulcerated foot; stage 4, an infected foot; and stage 5, a necrotic foot. This covers the entire spectrum of foot disease but emphasises the development of the foot ulcer as a pivotal event in stage 3, which demands urgent and aggressive management. Diabetic foot care in all stages needs multidisciplinary management to control mechanical, wound, microbiological, vascular, metabolic and educational aspects. Achieving good metabolic control of blood glucose, lipids and blood pressure is important in each stage, as is education to teach proper foot care appropriate for each stage. Ideally, it is important to prevent the development of ulcers in stages 1 and 2. In stage 1, the normal foot, it is important to encourage the use of suitable footwear, and to educate the patient to promote healthy foot care and footwear habits. In stage 2, the foot has developed one or more of the following risk factors for ulceration: neuropathy, ischaemia, deformity, swelling and callus. The majority of deformities can be accommodated in special footwear and as callus is an important precursor of ulceration it should be treated aggressively, especially in the neuropathic foot. In stage 3, ulcers can be divided into two distinct entities: those in the neuropathic foot and those in the neuroischaemic foot. In the neuropathic foot, ulcers commonly develop on the plantar surface of the foot and the toes, and are associated with neglected callus and high plantar pressures. In the neuroischaemic foot, ulcers are commonly seen around the edges of the foot, including the apices of the toes and back of the heel, and are associated with trauma or wearing unsuitable shoes. Ulcers in stage 3 need relief of pressure (mechanical control), sharp debridement and dressings (wound control), and

Duodenal diversion can ameliorate lipid and glucose metabolism. We assessed the risk of stroke after subtotal gastrectomy with Billroth II anastomosis (SGBIIA) in peptic ulcer disease (PUD). We identified 6425 patients who received SGBIIA for PUD between 1998 and 2010 from the Taiwan National Health Insurance Research Database as the study cohort; we frequency-matched them with 25,602 randomly selected controls from the PUD population who did not receive SGBIIA according to age, sex, index year, and comorbidities including hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, congestive heart failure, chronic kidney disease, chronic obstructive pulmonary disease (COPD), and obesity. All patients were followed until the end of 2011 to determine the incidence of stroke. The incidence of stroke was lower in patients in the SGBIIA cohort than in those in the non-SGBIIA cohort (18.9 vs 22.9 per 1000 person-years, adjusted hazard ratio [aHR] 0.80, 95% confidence interval [CI] 0.72-0.89, P < 0.001). The risk of ischemic stroke (aHR 0.77, 95% CI 0.69-0.86, P < 0.001), rather than hemorrhagic stroke (aHR 1.00, 95% CI 0.78-1.28), was lower for the SGBIIA cohort than for the non-SGBIIA cohort according to the multivariable Cox proportional hazard regression analysis. The relative risk of ischemic stroke after SGBIIA was lower in men (aHR 0.77, 95% CI 0.69-0.86) than in women (aHR 0.80, 95% CI 0.65-0.99) and in patients aged ≥65 years (aHR 0.72, 95% CI 0.63-0.81) than in those of other age groups (≤49 years, aHR 0.82, 95% CI 0.48-1.39; 50-64 years, aHR 1.01, 95% CI 0.79-1.28). The relative risk of ischemic stroke after SGBIIA was also reduced in patients with comorbidities (aHR 0.84, 5% CI 0.75-0.95) rather than in those without comorbidities (aHR 0.81, 95% CI 0.59-1.12). SGBIIA is associated with a low risk of ischemic stroke for PUD patients, and its protective effect is prominent in men, patients aged ≥65 years, and those with comorbidities.
Full Text Available Introduction Choledochoduodenal fistulas are very rare and in most cases are caused by a long-lasting and poorly treated chronic duodenal ulcer. They may be asymptomatic or followed by symptoms of ulcer disease, by attacks of cholangitis or bleeding or vomiting in cases of ductoduodenal stenosis. The diagnosis is simple and safe, however treatment is still controversial. If surgery is the choice of treatment, local findings should be taken into consideration. As a rule, intervention involving closure of fistula is not recommended. Case Outline The authors present a 60-year-old woman with a long history of ulcer disease who developed attacks of cholangitis over the last three years. Ultrasonography and CT showed masive pneumobilia due to a choledochoduodenal fistula. . As there was no duodenal stenosis or bleeding, at operation the common bile duct was transected and end-to-side choledochojejunostomy was performed using a Roux-en Y jejunal limb. From the common bile duct, multiple foreign bodies of herbal origin causing biliary obstruction and cholangitis were removed. After uneventful recovery the patient stayed symptom free for four years now. Conclusion The performed operation was a simple and good surgical solution which resulted in complication-free and rapid recovery with a long-term good outcome. .
Inflammatory Bowel disease (IBD) is a condition characterised by chronic recidivous inflammation of the bowel and intestine. IBD includes chron´s disease (CD) and ulcerative colitis (UC). The combined prevalence of CD and UC are app. 1 in 500 in the general Caucasian population. In 25% of the cases...

BACKGROUND: The etiology of the inflammatory bowel diseases, including ulcerative colitis (UC), remains incompletely explained. We hypothesized that an analysis of the UC colon proteome could reveal novel insights into the disease etiology. METHODS: Mucosal colon biopsies were taken by endoscopy...

C. pyloridis colonization was investigated in a selected group of 58 patients with upper gastrointestinal disorders submitted to endoscopy and biopsy. The following results were registered. C. pyloridis was isolated in 14 out of 18 cases of active chronic gastritis, in 15 out of 24 cases of non active chronic gastritis, and 7 out of 8 cases of antral ulceration. A negative finding was registered in 8 patients whose gastric mucosa was normal. Therefore, the Authors consider as valid the etiopathogenetic correlation between C. pyloridis and ulcerative or non-ulcerative chronic gastric diseases, suggested by others.

A 48-year-old female with severe ulcerative colitis refractory to conventional therapy was referred to our facility for management. The patient showed extensive ulcerative colitis since the age of 20 years and had failed therapy with 5-aminosalicylic acid agents and azathioprine. The disease remained active despite treatment with steroids and cyclosporine. The clinical and endoscopic parameters were consistent with severe disease. Infectious precipitants were ruled out. Given the severity of the disease and in order to avoid a colectomy, we started the patient on infliximab therapy. A dramatic clinical and endoscopic response was observed and she remained in remission at the end of a 1-year follow-up period. We discuss findings in the literature regarding the use of infliximab therapy in patients with ulcerative colitis who have failed steroids and cyclosporine.
Full Text Available Crohn's disease (CD is notably characterized by the expansion of visceral fat with small adipocytes expressing a high proportion of anti-inflammatory genes. Conversely, visceral fat depots in ulcerative colitis (UC patients have never been characterized. Our study aims were a to compare adipocyte morphology and gene expression profile and bacterial translocation in omental (OM and mesenteric (MES adipose tissue of patients with UC and CD, and b to investigate the effect of bacterial infection on adipocyte proliferation in vitro. Specimens of OM and MES were collected from 11 UC and 11 CD patients, processed and examined by light microscopy. Gene expression profiles were evaluated in adipocytes isolated from visceral adipose tissue using microarray and RTqPCR validations. Bacteria within adipose tissue were immuno-detected by confocal scanning laser microscopy. Adipocytes were incubated with Enterococcus faecalis and cells counted after 24 h. Morphology and molecular profile of OM and MES revealed that UC adipose tissue is less inflamed than CD adipose tissue. Genes linked to inflammation, bacterial response, chemotaxis and angiogenesis were down-regulated in adipocytes from UC compared to CD, whereas genes related to metallothioneins, apoptosis pathways and growth factor binding were up-regulated. A dense perinuclear positivity for Enterococcus faecalis was detected in visceral adipocytes from CD, whereas positivity was weak in UC. In vitro bacterial infection was associated with a five-fold increase in the proliferation rate of OM preadipocytes. Compared to UC, visceral adipose tissue from CD is more inflamed and more colonized by intestinal bacteria, which increase adipocyte proliferation. The influence of bacteria stored within adipocytes on the clinical course of IBD warrants further investigations.
Full Text Available OBJECTIVES: Ulcerative colitis (UC is a relapsing inflammatory disorder of unconfirmed aetiology, variable severity and clinical course, characterised by progressive histological inflammation and with elevation of eicosanoids which have a known pathophysiological role in inflammation. Therapeutic interventions targetting eicosanoids (5-aminosalicylates (ASA are effective first line and adjunctive treatments in mild-moderate UC for achieving and sustaining clinical remission. However, the variable clinical response to 5-ASA and frequent deterioration in response to cyclo-oxygenase (COX inhibitors, has prompted an in depth simultaneous evaluation of multiple lipid mediators (including eicosanoids within the inflammatory milieu in UC. We hypothesised that severity of inflammation is associated with alteration of lipid mediators, in relapsing UC. DESIGN: Study was case-control design. Mucosal lipid mediators were determined by LC-MS/MS lipidomics analysis on mucosal biopsies taken from patients attending outpatients with relapsing UC. Univariate and multivariate statistical analyses were used to investigate the association of mucosal lipid mediators, with the disease state and severity graded histologically. RESULTS: Levels of PGE2, PGD2, TXB2, 5-HETE, 11-HETE, 12-HETE and 15-HETE are significantly elevated in inflamed mucosa and correlate with severity of inflammation, determined using validated histological scoring systems. CONCLUSIONS: Our approach of capturing inflammatory mediator signature at different stages of UC by combining comprehensive lipidomics analysis and computational modelling could be used to classify and predict mild-moderate inflammation; however, predictive index is diminished in severe inflammation. This new technical approach could be developed to tailor drug treatments to patients with active UC, based on the mucosal lipid mediator profile.
The incidence of pressure ulcers in acutely ill infants and children ranges up to 27 percent in intensive care units, with a range of 16-19 percent in NICUs. Anatomic, physiologic, and developmental factors place ill and preterm newborns at risk for skin breakdown. Two case studies illustrate these factors, and best practices for pressure ulcer prevention are described.

Duodenal ulcer cure, as a systemic gastroenterologic disease, can be achieved in some patients by the addition of the nootropic drug piracetam to current antisecretory and antihelicobacter therapy. Piracetam corrects vegetative and psychoemotional disorders in duodenal ulcer, normalizes gastric motility, has an antioxidant effect and improves cerebral circulation. An optimal effect on clinico-endoscopic manifestations of recurrent duodenal ulcer was achieved in combination of piracetam with current antisecretory (omeprazole) and antihelicobacter (de-nol, amoxicillin, metronidazole) medicines. Such combination improves both short- and long-term outcomes of duodenal ulcer treatment.
