    Immunohistochemical studies of Harderian gland, cecal tonsil and trachea of various groups of broiler chickens and the response of Baby Chick Ranikhet Disease Vaccines (BCRDV) on the mobilization of Igs-cells during postnatal development of organs was investigated in the Dept. of Anatomy and Histology, Bangladesh Agricultural University, Mymensingh. In this study twelve chickens were grouped into vaccinated broilers (D14 and D28) which had received vaccines first at D3 of age and a booster dose given at D13; and non-vaccinated broilers (D1) which had not been vaccinated. In this study, it was observed that the frequency and distribution of Igs-positive cells were higher at D14 and at D28 rather than D1. Among Igs-positive cells, the IgG-positive cells were significantly higher than IgM and IgA-positive cells in the Harderian gland of D14 and D28 groups of chickens, however, in day-old chickens, the frequency of IgM-positive cells in this gland were greater. In the cecal tonsil, the frequency and distribution of IgG-positive cells were significantly higher than IgA- and IgM-positive cells both at D14 and D28 ages of chicken. On the other hand, in day-old chickens, the frequency and distribution of IgA-positive cells were insignificantly greater, followed by IgM and IgG-positive cells. In the trachea, few immunoglobulin-containing plasma cells were distributed in the subepithelial layer. IgM-positive cells were higher followed by IgG and IgA-positive cells in the trachea in D14 and D28 groups of chickens. In the same organ, IgG-positive plasma cells were greater than IgA and IgM-positive cells at one-day old. When the data for Harderian gland, cecal tonsil and trachea were compared statistically, it was observed that Igs-positive cells were statistically more common in cecal tonsils in day old chickens, and with the advancement of age, Igs-positive cells were found more in the Harderian gland. In conclusion, with the advancement of age in chickens the Harderian gland

    Full Text Available Por definición, se llama apendicitis retro-cecal a la inflamación aguda o crónica del apéndice, cuando está situado en posición retrocecal,sea que acompañe a un ciego móvil y en consecuencia esté provisto de meso, o bien que con ciego fijo se encuentre sin meso y en posición retro-peritoneal, hallándose entonces en íntima relación con algunas formaciones anatómicas como el tejido conjuntivo peri-renal, el nervio génito.crural derecho, el fémoro cutáneo, el obsturador y el uréter derecho. Con la mayor frecuencia y cuando el diagnóstico de apendicitis no se ha comprobado previamente por medio de los rayos X la situación retro-cecal es un hallazgo operatorio, que por no haber sido pre visto puede ocasionar dificultades técnicas más o menos grandes y prolongar, a veces por mucho tiempo el acto quirúrgico. Es importante, conocer la sintomatologíade la apendicitis retrocecal, puesto que es posible confundir esta afección, con otras que están situadas en órganos ajenos al tractus digestivo, como son (Bockus, Duplay, la litiasis renal, la pielitis derecha o los abscesos peri-nefríticos, confusiones éstas que son muy graves porque o bien pueden demorar la intervención quirúrgica, o bien la indican de inmediato cuando está formalmente contraindicada, como ocurre en las dos primeras afecciones mencionadas.

    Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

    Full Text Available Idiopathic isolated cecal necrosis is a clinical problem characterized by right-sided inferior abdominal pain. It is rarely seen, develops due to decreased blood flow to the colon and, imitates acute appendicitis. Its clinical signs are similar to many illnesses causing sensitivity in the right inferior quadrant and, the diagnosis is generally determined during surgery. An 86-year-old male patient presented with the complaints of abdominal pain, trichiniasis, nausea and vomiting. Surgical intervention was decided when physical examination and laboratory results were taken into consideration. After diagnostic laparoscopy, right hemicolectomy was performed because of cecal necrosis. While the mortality and morbidity rates for ischemic bowel disease are high, prognosis for early diagnosed patients with isolated cecal necrosis is better, provided that timely surgical treatment is decided.

    Full Text Available Cecal perforation is an uncommon phenomenon in a pediatric population. It has been linked to a number of underlying medical conditions, which may result in focal inflammation or relative ischemia including hematologic malignancy, infection, and inflammatory bowel disease. We present an otherwise healthy 16-year-old male diagnosed with acute uncomplicated appendicitis on ultrasound, who was found to have cecal perforation with normal appendix intraoperatively, ultimately requiring ileocectomy. With this report, we aim to present the numerous pathophysiologic etiologies of cecal perforation, and to promote a comprehensive differential diagnosis despite the clinical and radiologic findings consistent with uncomplicated appendicitis.

    2017-02-01

    Cecal diverticulitis is a rare disease process, particularly in children. Patients predictably present with right lower quadrant abdominal pain in a manner similar to appendicitis. Imaging may reveal a phlegmon, perforation, bowel wall thickening, or nonspecific inflammatory changes. These imaging findings may not always indicate a clear diagnosis, especially if the appendix cannot be well visualized. Urgent operation may be ill advisable in this situation as the surgeon may encounter a hostile operative field with dense inflammatory changes resulting in an increased risk of ileostomy creation. We present a case of cecal diverticulitis managed safely with a delayed surgical approach. We feel a delayed surgical approach may provide an alternative option for patients with an uncertain diagnosis or surgeons who wish to avoid a potentially hazardous dissection. A delayed approach may also help to facilitate a minimally invasive approach.

    Patients with multiple comorbidities often develop decreased intestinal motility resulting in abdominal distention. A variety of etiologies such as electrolyte abnormalities, medications, and sometimes unusual anatomical pathologies are responsible for this distention. Cecal bascule represents an exceedingly rare anatomical variance that leads to abdominal distention, and mimics a potentially isolated cecal distention. This rare diagnosis, if missed, can lead to severe complications. We prese...

    Broccoli consumption brings many health benefits, including reducing the risk of cancer and inflammatory diseases. The objectives of this study were to identify global alterations in the cecal microbiota composition using 16S rRNA sequencing analysis and glucoraphanin (GRP) hydrolysis to isothiocyanates ex vivo by the cecal microbiota, following different broccoli diets. Rats were randomized to consume AIN93G (control) or different broccoli diets; AIN93G plus cooked broccoli, a GRP-rich powder, raw broccoli, or myrosinase-treated cooked broccoli. Feeding raw or cooked broccoli for four days or longer both changed the cecal microbiota composition and caused a greater production of isothiocyanates ex vivo. A more than two-fold increase in NAD(P)H: quinone oxidoreductase 1 activity of the host colon mucosa after feeding cooked broccoli for seven days confirmed the positive health benefits. Further studies revealed that dietary GRP was specifically responsible for the increased microbial GRP hydrolysis ex vivo, whereas changes in the cecal microbial communities were attributed to other broccoli components. Interestingly, a three-day withdrawal from a raw broccoli diet reversed the increased microbial GRP hydrolysis ex vivo. Findings suggest that enhanced conversion of GRP to bioactive isothiocyanates by the cecal microbiota requires four or more days of broccoli consumption and is reversible.

    It has long been accepted that cecum and ileocecal valve are prime important area in GI roentgenology because of variety and frequency of primary and secondary disease involvement. However, precise preoperative diagnosis is still debatable roentrenologically. It is necessary to use the more descriptive terms and systemic approach for roentgenologic diagnosis in this area. Authors analyzed pathologically verified 54 cases of cecal lesion by double contrast colon examination at Yonsei University Medical College Severance Hospital from January '75 to September '80. Of the distribution of diseases, pericecal abscess (16/54; 29.6%) was most common, and followed by intestinal tuberculosis (9/54; 16.6%), and carcinoma (9/54; 16.6%) etc. The ratio of male and female was 2.18: 1 and peak incidence was above 4th decade. The majority of cases show right lower quadrant pain and palpable mass as clinical manifestation. Of the radiologic findings, abnormality in appendix such as nonfilling or irregular filling of barium suggest pericecal abscess, mucocele and less frequently adenocarcinoma of cecum, and characteristically pericecal abscess show rather smooth displacement of medial wall of cecum, but abrupt transition of lesion is shown in adenocarcinoma. Irritability and shortening of cecum, and fixation and speculation of terminal ileum were frequently found in inflammatory conditions such as pericecal abscess, intestinal tuberculosis and chronic nonspecific inflammation. Cecal lesion associated with involvement of ileocecal value were noted in intestinal tuberculosis, lymphoma and adenocarcinoma

    To describe three cases of solitary cecal diverticulum, and trying to evaluate the better method of diagnosis and treatment with analysis of the literature. Description of three cases of solitary cecal diverticulum's perforation admitted in the Department of General and Oncologic Surgery, Santa Maria della Misericordia Hospital, Perugia, during the period January 2011 - January 2012. In all patients the clinical presentation was very similar to that of acute appendicitis. Preoperative diagnosis was achieved in one case through abdominal CT scan, other two cases were identified at final pathology. At one year from the treatment all patient are still alive. Cecal diverticulum is a rare condition, often diagnosed either casually or because of inflammatory or perforative complications. The highest incidence is found in Western population. Because of the clinical presentation, very similar to the appendicitis, and the inflammatory reaction involving the colon and its surrounding tissues, the pre- and intra-operative diagnosis are very difficult. The diagnosis is almost always histological. The treatment may vary from simple expectant medical management, carried out with bowel rest, parenteral support and antibiotics as for left-sided diverticulitis, to surgical approach, performed through simple diverticulectomy or by classical right hemicolectomy. Pre-surgical and, also intra-operative, diagnosis of perforated solitary cecal diverticulum is clearly difficult. CT scan represents the gold standard for the differential diagnosis. Right hemicolectomy is an effective and safe approach, allowing accurate control, preventing complications and recurrences, and it represents the optimal management of the disease.

    Full Text Available Epizootic Rabbit Enteropathy (ERE is a severe disease of unknown aetiology that mainly affects post-weaning animals. Its incidence can be prevented by antibiotic treatment suggesting that bacterial elements are crucial for the development of the disease. Microbial dynamics and host responses during the disease were studied. Cecal microbiota was characterized in three rabbit groups (ERE-affected, healthy and healthy pretreated with antibiotics, followed by transcriptional analysis of cytokines and mucins in the cecal mucosa and vermix by q-rtPCR. In healthy animals, cecal microbiota with or without antibiotic pretreatment was very similar and dominated by Alistipes and Ruminococcus. Proportions of both genera decreased in ERE rabbits whereas Bacteroides, Akkermansia and Rikenella increased, as well as Clostridium, γ-Proteobacteria and other opportunistic and pathogenic species. The ERE group displayed remarkable dysbiosis and reduced taxonomic diversity. Transcription rate of mucins and inflammatory cytokines was very high in ERE rabbits, except IL-2, and its analysis revealed the existence of two clearly different gene expression patterns corresponding to Inflammatory and (mucin Secretory Profiles. Furthermore, these profiles were associated to different bacterial species, suggesting that they may correspond to different stages of the disease. Other data obtained in this work reinforced the notion that ERE morbidity and mortality is possibly caused by an overgrowth of different pathogens in the gut of animals whose immune defence mechanisms seem not to be adequately responding.

    Full Text Available Non specific cecal ulcer (NSCU is a rare entity described by Cruveilhier in 1832. NSCU has no specific presenting features and it can mimic a host of conditions like appendicitis, diverticulosis and colonic carcinoma. Earlier, this terminology was used to depict those ulcers where it was not possible to make the exact diagnosis. There are only a few cases where a specific preoperative diagnosis was made. The number of NSCUs being reported recently is less. This is due to the advent of newer diagnostic techniques to identify the etiology of these ulcers. Hence the term NSCU is no longer employed in current literature because a specific diagnosis is attained in most ulcers. Therefore the term NSCU is no longer valid and its use should be largely restricted to those cases where a specific diagnosis is not possible even after exhausting the currently available investigative techniques. This article provides an overview of this outdated term and outlines how to proceed when NSCU is encountered in clinical practice. [J Interdiscipl Histopathol 2013; 1(2.000: 85-88

    To clarify the functional properties of potato pulp (PP), a waste product resulting from extraction of starch from potatoes, we examined the effects of PP on cholesterol metabolism and cecal conditions in rats. Plasma total cholesterol (T-Chol) levels were lower in rats fed a PP-supplemented diet for four weeks than in those fed a control diet. Cecal pH was lowered due to an increase in the levels of cecal total short-chain fatty acids, especially butyrate, in the PP group compared to the control group. Furthermore, animals fed with the PP-supplemented diet showed increased cecal ratios of Lactobacillus and Clostridia and decreased cecal ratios of Bacteroides and Gammaproteobacteria with slightly negative and positive correlations with plasma T-Chol levels, respectively. In conclusion, ingestion of PP for four weeks is likely to improve both cecal conditions and cholesterol metabolism, suggesting that PP has prebiotic effects.

    Abstract Objective. The correlation between plasma Chromogranin A concentrations and changes in tumor size evaluated by computed tomography (CT) - as a gold standard - was evaluated. Material and methods. One hundred and sixteen patients with CgA-producing ileo-cecal neuroendocrine tumors were...... evaluated by events, which were recorded when a CT was followed by another CT 1 - 12 months later. Change in tumor size was defined as regression, progression, or stable disease using RECIST criteria 1.1. Of 426 events, there were 97 with progression, 279 with stable disease, and 50 with regression. Based...... on the ROC curves a cutoff value of 25% change was selected to discriminate between increased, decreased, or unchanged CgA concentrations in plasma, using a sensitive radioimmunoassay with well-defined epitope specificity. Results. In the 97 events showing tumor progression diagnostic sensitivity...

    Although previous studies have suggested that appendix seems to be involved in the colitis, the role of this in the pathogenesis remains unclear. In this study, we assessed the importance of appendiceal lymphoid follicles, specifically the cecal patches (CP) in mice, using an experimental colitis model. Treatment with oxazolone resulted in ulcerations particularly at CP with follicular expansion as well as colitis. The colitis was attenuated by either appendectomy or the absence of mature B cells. We therefore established an intravital imaging system accompanied by the fluorescence resonance energy transfer technology to analyze the dynamic immune response of CP B cells. Our observation revealed frequent Ca 2+ signaling in CP B cells during the early phase of colitis development. These findings suggested that the CP B cells may be involved in the pathogenesis of colitis including inflammatory bowel diseases in humans. Copyright © 2018 Elsevier Inc. All rights reserved.

    The authors presented a 75-year-old female patient at high risk, suspected of a cecal cancer (CC) due to discomfort in the inguinal fossa, microcytic anemia (although she was postmenopausal), liquid stools and a positive faecal occult blood test. A standard examination of the large intestine was undertaken. Conventional colonoscopy was not completed and the results of barium enema were questionable. Therefore, virtual colonoscopy (VC) was performed, which helped to localize an accurate operation site. As a result, the patient underwent right hemicolectomy. Postoperative histopathological assessment confirmed an advanced cecal cancer. Traditionally, double-contrast barium enema is used to evaluate the colon in patients after incomplete colonoscopy. However, the accuracy of this test is lower in comparison to endoscopy or VC. An incomplete colonoscopy examination may occur in up to 10% of patients. Tortuous course of the colon, diverticulosis, strictures, obstructing mass and fixation of colonic loops due to adhesions after surgery are the most common causes of incomplete examinations. To sum up, VC can be an alternative method of evaluation of the large bowel in patients after an incomplete colonoscopy examination, as follows from the presented case and the available literature.

    The use of surgical drains in abdominal surgery is still today controversial. While accepting their role in certain circumstances, their systematic use advocated by other schools, is not fully accepted. We present a case of secondary blind drilling drainage tube perineum following an abdominoperineal amputation of the rectum that forced a surgical repair in a neoplastic patient This is a patient who underwent abdomino perineal resection for rectal neoplasia. It was decided to leave a silicone-type drain tube for perineum and in late postoperative he presented cecum perforation due to traumatic introduction thereof into the cecal light, which forced his reoperation and surgical repair. There is a tendency to use less and less drains in abdominal surgery, although there are certain occasions when it becomes inevitable. On the other hand it entails morbidity associated with its use that significantly complicates and delays the recovery of the patient. It is accepted that is not useful to prevent the occurrence of fistulas, although it contributes to its early detection. The cecal perforation due to drain is a rare complication which must always be taken into account, and that perhaps could be avoided by using soft and less rigid drains. Copyright © 2015.

    Malrotation of the midgut is generally considered as a pediatric pathology with the majority of patients presenting in childhood. The diagnosis is rare in adults, which sometimes leads to delay in diagnosis and treatment. An index of suspicion is therefore required when dealing with patients of any age group with abdominal symptoms. We present a case of a 26-year-old male who presented with left lower abdominal pain with preoperative computed tomography showing suspected left-sided appendicitis associated with midgut malrotation. The duodenum, small bowel, and cecum were abnormally located, with the presence of a thickened and inflamed appendix with fecalith images. The patient underwent an emergency laparotomy, and ruptured cecal diverticulitis with abscess formation was confirmed. We performed a cecectomy, and the patient did not have an uneventful postoperative recovery. A review of the literature is presented to highlight the rarity of midgut malrotation and the controversies surrounding its surgical management in the adult population with ruptured left-sided cecal diverticulitis.

    Full Text Available With increasing pressures to reduce or eliminate the use of antimicrobials for growth promotion purposes in production animals, there is a growing need to better understand the effects elicited by these agents in order to identify alternative approaches that might be used to maintain animal health. Antibiotic usage at subtherapeutic levels is postulated to confer a number of modulations in the microbes within the gut that ultimately result in growth promotion and reduced occurrence of disease. This study examined the effects of the coccidiostat monensin and the growth promoters virginiamycin and tylosin on the broiler chicken cecal microbiome and metagenome. Using a longitudinal design, cecal contents of commercial chickens were extracted and examined using 16S rRNA and total DNA shotgun metagenomic pyrosequencing. A number of genus-level enrichments and depletions were observed in response to monensin alone, or monensin in combination with virginiamycin or tylosin. Of note, monensin effects included depletions of Roseburia, Lactobacillus and Enterococcus, and enrichments in Coprococcus and Anaerofilum. The most notable effect observed in the monensin/virginiamycin and monensin/tylosin treatments, but not in the monensin-alone treatments, was enrichments in Escherichia coli. Analysis of the metagenomic dataset identified enrichments in transport system genes, type I fimbrial genes, and type IV conjugative secretion system genes. No significant differences were observed with regard to antimicrobial resistance gene counts. Overall, this study provides a more comprehensive glimpse of the chicken cecum microbial community, the modulations of this community in response to growth promoters, and targets for future efforts to mimic these effects using alternative approaches.

    Two different fluid solutions were infused through percutaneous cecal catheters in 6 healthy ponies to determine the effects on body weight; CBC; packed cell volume (PCV); total plasma protein concentration; plasma fibrinogen concentration; abdominal fluid analysis; concentrations of blood urea nitrogen (BUN), serum creatinine, Ca, total CO2 (TCO2), Na, Cl, K, and P; and fractional clearance (FC) of Na, Cl, K, and P. During intracecal administration of solution 1, FCNa and FCCl were significantly increased, whereas FCK and BUN were significantly decreased. During administration of solution 2, FCNa and serum P were significantly increased, while PCV was significantly decreased. All ponies developed peritonitis during the study. Complications included catheter-related problems, diarrhea, laminitis, and hypocalcemia. We concluded that hydration and electrolyte balance could be maintained by administration of crystalloid solutions intracecally, but that complications were associated with the procedure.

    Colonoscopy plays a critical role in colorectal cancer (CRC) screening and has been widely regarded as the gold standard. Cecal intubation rate (CIR) is one of the well-defined quality indicators used to assess colonoscopy. To assess the impact of new technologies on the quality of colonoscopy by assessing completion rates. This was a dual-center study at the 2 nd Department of Surgery at Jagiellonian University Medical College and at the Specialist Center "Medicina" in Krakow, Poland. The CIR and cecal intubation time (CIT) in three different eras of technological advancement were determined. The study enrolled 27 463 patients who underwent colonoscopy as part of a national CRC screening program. The patients were divided into three groups: group I - 3408 patients examined between 2000 and 2003 (optical endoscopes); group II - 10 405 patients examined between 2004 and 2008 (standard electronic endoscopes); and group III - 13 650 patients examined between 2009 and 2014 (modern endoscopes). There were statistically significant differences in the CIR between successive eras. The CIR in group I (2000-2003) was 69.75%, in group II (2004-2008) was 92.32%, and in group III (2009-2014) was 95.17%. The mean CIT was significantly reduced in group III. Our study shows that the technological innovation of novel endoscopy devices has a great influence on the effectiveness of the CRC screening program. The new era of endoscopic technological development has the potential to reduce examination-related patient discomfort, obviate the need for sedation and increase diagnostic yields.

    Physical exercise can reduce adverse conditions during aging, while both exercise and aging act as metabolism modifiers. The present study investigates rat fecal and cecal metabolome alterations derived from exercise during rats' lifespan. Groups of rats trained life-long or for a specific period of time were under study. The training protocol consisted of swimming, 15-18 min per day, 3-5 days per week, with load of 4-0% of rat's weight. Fecal samples and cecal extracts were analyzed by targeted and untargeted metabolic profiling methods (GC-MS and LC-MS/MS). Effects of exercise and aging on the rats' fecal and cecal metabolome were observed. Fecal and cecal metabolomics are a promising field to investigate exercise biochemistry and age-related alterations.

  19. LaPlace's law revisited: Cecal perforation as an unusual presentation of pancreatic carcinoma

    2007-02-01

    Full Text Available Abstract Background Pancreatic cancer is often locally and distally aggressive, but initial presentation as cecal perforation is uncommon. Case presentation We describe a patient presenting with pneumoperitoneum, found at initial exploration to have a cecal perforation believed to be secondary to a large cecal adenoma, after palpation of the remainder of the colon revealed hard stool but no distal obstruction. Postoperatively, however, the patient progressed to large bowel obstruction and upon reexploration, a mass could now be delineated, encompassing the splenic flexure, splenic hilum, and distal pancreas. Histological evaluation determined this was locally invasive pancreatic adenocarcinoma, and therefore the true etiology of the original cecal perforation. Conclusion Any perforation localized to the cecum must be highly suspicious for a distal obstruction, as dictated by the law of LaPlace.

    The viscosity of gut contents should influence digestion and absorption. Earlier investigators measured the viscosity of intestinal contents after the removal of solid particles. However, we previously found that removal of solid particles from pig cecal contents dramatically lowered the viscosity of the contents. Accordingly, we examined the contribution of large solid particles to viscoelastic parameters of gut contents in the present study. We removed large particles from pig cecal contents by filtration through surgical gauze. Then, we reconstructed the cecal contents by returning all, one half or none of the original amount of the large particles to the filtrate. We measured the viscosity, shear stress and shear rate of these reconstructed cecal contents using a tube-flow viscometer. The coefficient of viscosity was larger when the large-particle content was higher (P Bingham plastic nature irrespective of large-particle content. We calculated the yield stress of these fluids assuming that the fluids behave as Bingham plastic. The yield stress of the cecal contents was greater (P Bingham plastic characteristics to pig cecal contents.

    The microbiome is now widely recognized as being important in health and disease, and makes up a substantial subset of the biome within the ecosystem of the vertebrate body. At the same time, multicellular, eukaryotic organisms such as helminths are being recognized as an important component of the biome that shaped the evolution of our genes. The absence of these macroscopic organisms during the early development and life of humans in Western culture probably leads to a wide range of human immunological diseases. However, the interaction between the microbiome and macroscopic components of the biome remains poorly characterized. In this study, the microbiome of the cecum in rats colonized for 2 generations with the small intestinal helminth Hymenolepis diminuta was evaluated. The introduction of this benign helminth, which is of considerable therapeutic interest, led to several changes in the cecal microbiome. Most of the changes were within the Firmicutes phylum, involved about 20% of the total bacteria, and generally entailed a shift from Bacilli to Clostridia species in the presence of the helminth. The results point toward ecological relationships between various components of the biome, with the observed shifts in the microbiome suggesting potential mechanisms by which this helminth might exert therapeutic effects.

  2. Differential responses of cecal microbiota to fishmeal, Eimeria and Clostridium perfringens in a necrotic enteritis challenge model in chickens.

    Directory of Open Access Journals (Sweden)

    Full Text Available Clostridium perfringens causes enteric diseases in animals and humans. In poultry, avian-specific C. perfringens strains cause necrotic enteritis, an economically significant poultry disease that costs the global industry over $2 billion annually in losses and control measures. With removal of antibiotic growth promoters in some countries this disease appears to be on the rise. In experimental conditions used to study disease pathogenesis and potential control measures, reproduction of the disease relies on the use of predisposing factors such as Eimeria infection and the use of high protein diets, indicating complex mechanisms involved in the onset of necrotic enteritis. The mechanisms by which the predisposing factors contribute to disease progression are not well understood but it has been suggested that they may cause perturbations in the microbiota within the gastrointestinal tract. We inspected changes in cecal microbiota and short chain fatty acids (SCFA induced by Eimeria and fishmeal, in birds challenged or not challenged with C. perfringens. C. perfringens challenge in the absence of predisposing factors did not cause significant changes in either the alpha or beta diversity of the microbiota nor in concentrations of SCFA. Moreover, there was no C. perfringens detected in the cecal microbiota 2 days post-challenge without the presence of predisposing factors. In contrast, both fishmeal and Eimeria caused significant changes in microbiota, seen in both alpha and beta diversity and also enabled C. perfringens to establish itself post challenge. Eimeria had its strongest influence on intestinal microbiota and SCFA when combined with fishmeal. Out of 6 SCFAs measured, including butyric acid, none were significantly influenced by C. perfringens, but their levels were strongly modified following the use of both predisposing factors. There was little overlap in the changes caused following Eimeria and fishmeal treatments, possibly indicating

    Full Text Available Campylobacteriosis is a zoonosis, a disease transmitted to humans from animals or animal products. The primarily source of Campylobacter infection in human is believed to be the handling and/or consumption of contaminated meat, especially poultry meat. Although in humans such infections are generally self-limiting, complications can arise and may include bacteraemia, Guillain-Barré syndrome, reactive arthritis and abortion. In this study, 32 birds were divided in 2 groups: a control (C group and an inoculated (I group, with 16 birds each. The I group was inoculated orally with 108 CFU/mL of Campylobacter jejuni ATCC 33291, whereas the C group was inoculated with a saline solution. Four chicks per group were euthanized by cervical dislocation at 0, 7, 14 and 21 days post-inoculation (pi. Cecum samples were collected for microbiological analyses. The samples were processed by two plate count methodologies, one developed by the USDA (United States Department of Agriculture in 2011 (B method and the other a serial dilution direct count method (A method. All birds from the C group remained negative until day 21. For the I group, the B method was found to be statistically superior to the A method for counting the recovered cells from the cecal contents at 7, 14 and 21 days pi. The microbiological direct plating counting method is a cost effective and rapid method to determine the level of contamination in broilers to help risk assessment programs at the industry level.

    Full Text Available Amebiasis is quite uncommon in developed countries. Its clinical presentation can vary from an asymptomatic carrier state to fulminant colitis and colonic perforation. We presented a 39-year-old female who received combined chemotherapy and radiotherapy for nasopharyngeal carcinoma 1 year prior to admission. Thereafter, she felt acute abdominal pain and diarrhea after traveling to Hainan 3 months ago. A physical examination of the patient revealed diffused peritoneal sign. Abdominal computed tomography showed a cecal tumor and intra-abdominal abscess. A subsequent exploratory laparotomy revealed an infiltrating yellowish tumor about 7 cm over the cecum and massive serous ascites. Pathology reported ambeic colitis with undermined ulcer and abscess formation of the cecum. Ameboma can be found in developed countries, particularly in patients with risk factors and a history of traveling to areas with the developing disease. Colonoscopy with biopsy is recommended for patients with suspected ameboma, and surgical intervention is likely indicated in complicated cases although the surgical mortality rate is high.

    This experiment was conducted to evaluate the effects of feeding dietary fiber on cecal short-chain fatty acid (SCFA) concentration and cecal microbiota of broiler and laying-hen chicks. The lower fiber diet was based on corn-soybean meal (SBM) and the higher fiber diet was formulated using corn-SBM-dried distillers grains with solubles (DDGS) and wheat bran to contain 60.0 g/kg of both DDGS and wheat bran from 1 to 12 d and 80.0 g/kg of both DDGS and wheat bran from 13 to 21 d. Diets were formulated to meet or exceed NRC nutrient requirements. Broiler and laying-hen chicks were randomly assigned to the high and low fiber diets with 11 replicates of 8 chicks for each of the 4 treatments. One cecum from 3 chicks was collected from each replicate: one cecum underwent SCFA concentration analysis, one underwent bacterial DNA isolation for terminal restriction fragment length polymorphism (TRFLP), and the third cecum was used for metagenomics analyses. There were interactions between bird line and dietary fiber for acetic acid (P = 0.04) and total SCFA (P = 0.04) concentration. There was higher concentration of acetic acid (P = 0.02) and propionic acid (P effect of dietary fiber on SCFA concentration and modulation of cecal microbiota in broiler and laying-hen chicks. © 2015 Poultry Science Association Inc.

    Full Text Available Prokinetic drugs are used for the management of gastrointestinal motility disorders in horses; however, little is known about their efficacy in donkeys. Therefore, the aim of the present study was to evaluate the effect of different doses of mosapride citrate on duodenal and cecal motility in normal donkeys. Six donkeys (n = 6 were used in a crossover study. Mosapride citrate was administered orally via a nasogastric tube at dose rate of 1, 2 and 3 mg kg−1. Duodenal and cecal motility were evaluated using ultrasonography before administration and at 15, 30, 60, 120 and 180 min post-administration. There was a significant increase of duodenal contractions (p < 0.05 after 30 min of mosapride citrate administration at 3 mg kg−1 with a prolonged (p < 0.05 prokinetic effect at 2 mg kg−1. Cecal contractions were significantly increased (p < 0.05 after 15 min at different doses of mosapride with a prolonged effect at 3 mg kg−1. The results of the present study indicate that mosapride citrate has a dose-dependent prokinetic effect on the duodenal and cecal contractions in healthy donkeys. Further studies need to determine whether mosapride citrate is effective in treatment of intestinal disorders in donkey.

    Full Text Available The objective of this article was to report a case of cecal diverticulitis and point out the differential diagnosis of acute appendicitis. The clinical manifestations of these pathological conditions are similar, and the accurate diagnosis of cecal diverticulitis before the surgery is difficult. Therefore, most diagnoses are made during the surgery. Moreover, cecal diverticulum is uncommon in western countries, but it is prevalent in Asian people and their descendants. We report a case of a 55-year-old female patient, whose imaging exams (ultrasonography and computed tomography and blood tests were not enough to diagnose the affection, requiring laparotomy and pathological exams for the final diagnosis. Some studies suggesting the best practice in case of diverticulum of the cecum were revised, as the diagnosis usually occurs during the surgery.O objetivo deste trabalho foi relatar um caso de diverticulite no ceco e chamar a atenção para o diagnóstico diferencial com apendicite aguda. As manifestações clínicas das duas afecções são semelhantes, dificultando o diagnóstico exato de diverticulite cecal, além de ser incomum, em nosso meio, o aparecimento de divertículo em cólon direito, sendo essa entidade mais comum em asiáticos e em seus descendentes. Relata-se atendimento a uma paciente de 55 anos, cujos exames de imagem (ultrassonografia e tomografia computadorizada e de sangue não foram suficientes para o diagnóstico. Houve necessidade de realizar-se laparotomia exploradora e exames anatomopatológicos para a confirmação. Também foram revisados alguns trabalhos que sugerem qual a melhor conduta a ser tomada quando se encontra divertículo cecal no perioperatório, já que, na maioria das vezes, o diagnóstico é feito neste momento.

    Colonoscopy is widely used for management of colorectal diseases. A history of abdominal or pelvic surgery is a well-recognized factor associated with difficult colonoscopy. Although water exchange colonoscopy (WEC) was effective in small groups of male U.S. veterans with such a history, its application in other cultural settings is uncertain. To investigate the application of WEC in such patients. Prospective, randomized, controlled, patient-blinded study. Tertiary-care referral center in China. Outpatients with prior abdominal or pelvic surgery undergoing unsedated diagnostic, screening, or surveillance colonoscopy. Patients were randomized to examination by either WEC or conventional air colonoscopy (AC). Cecal intubation rate. A total of 110 patients were randomized to the WEC (n = 55) or AC (n = 55) group. WEC significantly increased the cecal intubation rate (92.7% vs 76.4%; P = .033). The maximum pain scores (± standard deviation) were 2.1 ± 1.8 (WEC) and 4.6 ± 1.7 (AC), respectively (P WEC would be willing to have a repeat unsedated colonoscopy (90.9% vs 72.7%, P = .013). Single center; unblinded but experienced endoscopists. This randomized, controlled trial confirms that the water exchange method significantly enhanced cecal intubation in potentially difficult colonoscopy in unsedated patients with prior abdominal or pelvic surgery. The lower pain scores and higher proportion accepting repeat of the unsedated option suggest that WEC is promising. It may enhances compliance with colonoscopy in specific populations.

    Čermák L.

    2016-09-01

    Full Text Available Differences in quantity of cecal microbiota in broiler chickens from conventional and pasture rearing were investigated by cultivation. Rearing on pasture brings stress reduction and increases comfort and bird welfare, which leads to products with better taste and flavour compared to conventionally produced broiler chickens. A difference in cecal settlement of general anaerobes, coliforms, lactic acid bacteria, and campylobacters and salmonellas in the two different rearing systems was addressed. Whereas numbers of total anaerobes and lactic acid bacteria were not affected, those of coliforms were significantly reduced in pasture rearing. Campylobacters were found only in pasture-reared chickens (in 28% of animals. Salmonellas were not detected in any of the systems.

Dynamic models were d...... sugars for the starch-rich diet and monosaccharides for the fiber-rich diet. In conclusion, diet may not only affect the composition of the cecal microbiota, but also dynamic interactions and metabolic cross-feeding....... diet, with Streptococcus spp. and Anaerovibrio spp. showing the largest fluctuations. Shotgun metagenome sequencing revealed that diet differences may be explained by modular switches in metabolic cross-feeding between microbial consortia in which fermentation is linked to sugar alcohols and amino...

    Dietary fiber/starch imbalance can lead to diarrhea in rabbits. However, the underlying molecular mechanisms are largely unknown, and this is the first study on the proteome profile of the cecal tissue of diarrheic rabbits. In this study, one group of weanling rabbits was fed a high fiber/starch diet (control group), and another group was fed a low fiber/starch diet (diarrhea group). We applied 2-D gel electrophoresis, coupled with histological and biochemical analyses, to study dynamic changes in the proteome of the cecal tissue from healthy and diarrheic growing rabbits. We identified 29 protein spots showing differential abundance between the two groups. We identified the proteins and found that they participated in key biological processes, including absorption, digestion and transport; cell structure and motility; inflammatory response; glucose and energy metabolism; mineral and vitamin metabolism; stress response and cell redox homeostasis. Moreover, the results of our proteomics analysis revealed continuous impairment and compensatory intestinal repair in the rabbits with diarrhea. Therefore, these findings shed light on the main mechanisms and the main proteins involved in intestinal degradation in diarrhea. These findings have important implications for understanding the mechanism of cecal damage and repair in diarrhea in rabbits caused by dietary factors. The different cecal protein expressions were compared between healthy and diarrhea in growing rabbit model fed different fiber/starch diets. Diarrhea caused by feeding high-starch diet induced mucosal injury and inflammation. In this work we identify protein spots by MALDI-TOF MS and classify by biological function. The finding that the expression of all other proteins belonging to seven functional groups was significantly increased in the diarrheic rabbits, except for CMBL, suggests that many intestinal functional proteins may be related to up-regulation, such as cell absorption, digestion, transport

    Full Text Available Antimicrobials are sometimes given to food animals at low doses in order to promote faster growth. However, the mechanisms by which those drugs improve performance are not fully understood. This study aimed to investigate the impact of zinc bacitracin (55g/ton, enramycin (10g/ton; halquinol® (30g/ton; virginiamycin (16,5g/ton and avilamycin (10g/ton on the cecal microbiota of broiler chicken, compared to a control group. Six hundred and twenty four chicks (Cobb 500 arriving to an experimental unit were randomly assigned into each treatment with four repetitions per treatment. The cecal content of 16 animals per treatment (n = 96 was used for DNA extraction and sequencing of the V4 region of the 16S rRNA gene using Illumina technology. The use of antimicrobials induced significant changes in membership but not in structure of the cecal microbiota compared to the control group, suggesting a greater impact on the less abundant species of bacteria present in that environment. Halquinol was the only drug that did not affect microbial membership. Firmicutes comprised the major bacterial phylum present in the cecum of all groups. There was no statistical difference in relative abundances of the main phyla between treated animals and the control group (all P>0.05. Treatment with enramycin was associated with decreased richness and with lower relative abundance of unclassified Firmicutes, Clostridium XI, unclassified Peptostreptococcaceae (all P<0.001 and greater abundance of Clostridium XIVb (P = 0.004 and Anaerosporobacter spp. (P = 0.015, and treatment with bacitracin with greater relative abundance of Bilophila spp. (P = 0.004. Several bacterial genera were identified as representative of usage of each drug. This study used high throughput sequencing to characterize the impact of several antimicrobials in broiler chicken under controlled conditions and add new insights to the current knowledge on how AGPs affect the cecal microbiota of chicken.

    Full Text Available The current study aimed to investigate the effects of different levels of copper sulfate on the growth performance and cecal ecosystem in newly weaned piglets. One hundred piglets weaned at 28±2 d were randomly allocated to 4 treatments with 5 replicates of 5 piglets each. Piglets received for 28 d the base diet with i no addition (control or with copper addition (from copper sulfate at ii 100, iii 175, and iv 250 mg/kg–1. On day 21, twenty piglets were randomly selected (one from each replicate to slaughter and investigate the population and diversity of cecal microorganisms. The results showed that the diets containing 175 and 250 mg/kg–1 copper improved the average daily gain (ADG by 51% and 60% and decreased the feed to gain ratio (F/G by 21% and 16%, respectively. Adding 175 or 250 mg/kg–1 copper improved crude protein, ether extract, calcium and phosphorus digestibility. Viable counts of Enterobacteriaceae and Lactobacilli in cecum tended to be reduced, while the concentrations of cecal volatile fatty acids (VFA were increased in pigs fed diet supplemented as copper level increased. Polymerase chain reaction (PCR results showed that adding 175 or 250 mg/kg–1 copper reduced the lactobacilli in cecum. Denaturing gradient gel electrophoresis (DGGE maps showed that band numbers and intensity of cecal bacterial 16S rDNA decreased as the copper levels increased. The results suggested that the effects of high dietary copper on microflora and their activities and metabolic products might contribute to the intestinal health and result in improved growth performance.

    Preservation of indigenous gastrointestinal microbiota is deemed to be critical for successful captive breeding of endangered wild animals, yet its biology is poorly understood. Here, we investigated cecal bacterial communities in wild Japanese rock ptarmigans (Lagopus muta japonica) and compared them with those in Svalbard rock ptarmigans (L. m. hyperborea) in captivity. Ultra-deep sequencing of 16S rRNA gene indicated that the community structure of cecal microbiota in wild rock ptarmigans was remarkably different from that in captive Svalbard rock ptarmigans. Fundamental differences between bacterial communities in the two groups of birds were detected at the phylum level. Firmicutes, Actinobacteria, Bacteroidetes and Synergistetes were the major phyla detected in wild Japanese rock ptarmigans, whereas Firmicutes alone occupied more than 80% of abundance in captive Svalbard rock ptarmigans. Furthermore, unclassified genera of Coriobacteriaceae, Synergistaceae, Bacteroidaceae, Actinomycetaceae, Veillonellaceae and Clostridiales were the major taxa detected in wild individuals, whereas in zoo-reared birds, major genera were Ruminococcus, Blautia, Faecalibacterium and Akkermansia. Zoo-reared birds seemed to lack almost all rock ptarmigan-specific bacteria in their intestine, which may explain the relatively high rate of pathogenic infections affecting them. We show evidence that preservation and reconstitution of indigenous cecal microflora are critical for successful ex situ conservation and future re-introduction plan for the Japanese rock ptarmigan.

    A broiler study was performed to determine the pre-cecal phosphorus (P) digestibility of 5 P sources, 3 from animal (Delfos, Calfos, and porcine bone meal) and 2 of inorganic (monocalcium phosphate [MCP] and dicalcium phosphate [DCP]) origin. Delfos is processed from bones resulting in a dicalcium phosphate product, and Calfos is processed from bones in which part of the gelatin is removed but in which the hydroxy-apatite matrix is preserved. During the first 14 d, birds were housed in floor pens bedded with wood shavings and received a commercial starter diet. At d 14, broilers were randomly assigned to pens (0.9 m2, 10 birds/pen) with a slatted floor. From d 14 onwards, one of the 6 experimental diets (a basal diet, and 5 diets containing the P sources) was provided. Test diets were replicated 6 times, and the basal diet 8 times. Electron microscopy images of test products were made in order to verify whether the spatial structure of the test products could be related to the pre-cecal P digestibility of the same products. Diets met or exceeded CVB (2011) requirements for all nutrients except for P and were formulated to contain a calcium to total P ratio of between 1.4 and 1.6 and a minimal amount of phytate P. Diets contained 5 g/kg titanium oxide as a marker to determine digestibility of P. At d 24 all birds were euthanized, after which the content of the terminal part of the ileum was sampled. The P digestibility was calculated by linear regression according to World's Poultry Science Association (WPSA) protocol for determination of pre-cecal P digestibility. Pre-cecal P digestibility of MCP, DCP, Delfos, Calfos, and porcine bone meal was 88.5, 82.4, 94.5, 86.9, and 78.2%, respectively. Based on visual inspection of electron microscopy images of test products, the spatial structure of the test products might be related to P digestibility. It is concluded that processing of bone meal increases the pre-cecal P digestibility in broilers. © The Author 2017

    The murine cecum is a critical digestive structure. Morphogenesis of the cecum involves several key genes, including Homeobox (Hox) d12. Ectopic expression of Hoxd12 has been shown to result in cecal agenesis and a down-regulation of both Fibroblast growth factor 10 (Fgf10) and the Pituitary homeobox 2 gene (Pitx2). Homozygous null mutation of Fgf10 or its cognate receptor Fgfr2IIIb results in severe cecal defects where there is the initiation of mesodermal budding, but a failure of the endoderm to grow and extend into this structure. We examined the expression of Pitx2 in the cecum and hypothesized that homozygous null mutation of Pitx2 would result in cecal agenesis. IACUC approval was obtained for these studies. Whole mount in situ hybridizations for Pitx2 were performed on wild-type embryos between embryonic d (E)11.0 and E12.5. Pitx2 -/- and Fgfr2IIIb -/- embryos were generated from n/+ heterozygote breedings and harvested at E10.5, E11.5, and E13.5. Genotypes were confirmed by PCR. Morphology of Pitx2 -/- cecae were compared with those of wild-type littermates and Fgfr2IIIb -/- embryos at identical stages. Embryos were fixed overnight and photographed the following day. Pitx2 is expressed in the cecal mesoderm and endoderm as early as E11.0. Expression becomes increasingly more robust by E12.5. Homozygous null mutation of Pitx2 results in agenesis of the cecum. In contrast to Fgfr2IIIb -/- embryos, which demonstrate a persistent mesodermal bud as late as E18.5, no mesodermal bud is present in Pitx2 -/- embryos. Our findings demonstrate that Pitx2 is a critical regulatory gene in cecal morphogenesis and suggest that Pitx2 is required for initiation of mesodermal budding and likely resides upstream of Fgf10-Fgfr2IIIb signaling in the normal development of this structure.

    The majority of chicken microbiota studies have used the ceca as a sampling site due to the specific role of ceca in chicken productivity, health and wellbeing. However, sampling from ceca and other gastrointestinal tract sections requires the bird to be sacrificed. In contrast, fecal sampling does not require sacrifice and thus allows the same bird to be sampled repeatedly over time. This is a more meaningful and preferred way of sampling as the same animals can be monitored and tracked for temporal studies. The commonly used practice of selecting a subset of birds at each time-point for sacrifice and sampling introduces added variability due to the known animal to animal variation in microbiota. Cecal samples and fecal samples via cloacal swab were collected from 163 birds across 3 replicate trials. DNA was extracted and 16S rRNA gene sequences amplified and pyrosequenced to determine and compare the phylogenetic profile of the microbiota within each sample. The fecal and cecal samples were investigated to determine to what extent the microbiota found in fecal samples represented the microbiota of the ceca. It was found that 88.55% of all operational taxonomic units (OTUs), containing 99.25% of all sequences, were shared between the two sample types, with OTUs unique for each sample type found to be very rare. There was a positive correlation between cecal and fecal abundance in the shared sequences, however the two communities differed significantly in community structure, represented as either alpha or beta diversity. The microbial populations present within the paired ceca of individual birds were also compared and shown to be similar. Fecal sample analysis captures a large percentage of the microbial diversity present in the ceca. However, the qualitative similarities in OTU presence are not a good representation of the proportions of OTUs within the microbiota from each sampling site. The fecal microbiota is qualitatively similar to cecal microbiota but

    Full Text Available The objective of this study was to evaluate the effects of different organic acids on bacterial growth and ammonia production by swine cecal microflora in an in vitro fermentation system. Formic, acetic, propionic, lactic, butyric, sorbic, fumaric, malic, citric, α-ketoglutaric, and benzoic acids were used at different concentrations (60, 120 and 240 mmol/l to assess if any effect on cecal microflora could be shown. Cecal microbial growth was evaluated using the cumulative gas production technique. Fermentation fluid was analyzed for ammonia concentration. Lactic acid was the only acid that enhanced bacterial fermentation at every concentration tested (+30%, 73%, and 35% gas final volume at 60, 120, and 240mmol/l, respectively; P<0.05. Citric acid strongly increased gas final volume when used at 60 and 120mmol/l (+92% and 52%, respectively; P<0.05 and almost completely inhibited bacterial activity at 240mmol/l (–85% gas final volume; P<0.05. Sorbic acid showed the strongest antibacterial activity and was the only acid that reduced final gas volume when used at 60 mmol/l (–34%; P<0.05. Only sorbic (–34%, 47%, and 67%, fumaric (–57%, 35%, and 26%, citric (–31%, 18%, and 28%, and benzoic (–33%, 29%, and 38% acids reduced ammonia after 24h of fermentation at any given concentration (P<0.05. Other acids, such as formic, acetic, propionic, butyric, and malic acids failed to exert an effective control of ammonia levels in the fermentation liquor. After the first set of fermentations, sorbic, α-ketoglutaric, and benzoic acids were further tested at the final concentration of 7.5, 15, and 30mmol/l. At these lower levels of inclusion, sorbic acid was the only acid that reduced final gas volume at every concentration tested (–31%, 35%, and 39% at 7.5, 15, and 30mmol/l, respectively; P<0.05. Compared with control, ammonia was reduced after 24h of fermentation by all treatments (with an average reduction of 34%, 20%, and 24% for sorbic,

    The chicken gut microbiota is an important and complicated ecosystem for the host. They play an important role in converting food into nutrient and energy. The coding capacity of microbiome vastly surpasses that of the host's genome, encoding biochemical pathways that the host has not developed. An optimal gut microbiota can increase agricultural productivity. This study aims to explore the composition and function of cecal microbiota in Dagu chicken under two feeding modes, free-range (outdoor, OD) and cage (indoor, ID) raising. Cecal samples were collected from 24 chickens across 4 groups (12-w OD, 12-w ID, 18-w OD, and 18-w ID). We performed high-throughput sequencing of the 16S rRNA genes V4 hypervariable regions to characterize the cecal microbiota of Dagu chicken and compare the difference of cecal microbiota between free-range and cage raising chickens. It was found that 34 special operational taxonomic units (OTUs) in OD groups and 4 special OTUs in ID groups. 24 phyla were shared by the 24 samples. Bacteroidetes was the most abundant phylum with the largest proportion, followed by Firmicutes and Proteobacteria. The OD groups showed a higher proportion of Bacteroidetes (>50 %) in cecum, but a lower Firmicutes/Bacteroidetes ratio in both 12-w old (0.42, 0.62) and 18-w old groups (0.37, 0.49) compared with the ID groups. Cecal microbiota in the OD groups have higher abundance of functions involved in amino acids and glycan metabolic pathway. The composition and function of cecal microbiota in Dagu chicken under two feeding modes, free-range and cage raising are different. The cage raising mode showed a lower proportion of Bacteroidetes in cecum, but a higher Firmicutes/Bacteroidetes ratio compared with free-range mode. Cecal microbiota in free-range mode have higher abundance of functions involved in amino acids and glycan metabolic pathway.

    Full Text Available Huang-Lian-Jie-Du-Tang (HLJDT is a traditional formula that has long been used for treatment of inflammatory diseases in Traditional Chinese Medicine. In this study, we examined its protective effect against sepsis in an experimental septic model induced by cecal ligation and puncture (CLP in rats. The results demonstrated that prophylactic administration of HLJDT protected rats from CLP-induced lethality and ameliorated CLP-induced liver and lung injury. HLJDT treatment suppressed the production of proinflammatory cytokines, including TNF-α, IL-1, IL-6, and IL-17A, indicating HLJDT could limit excessive inflammatory responses in septic condition. In addition, HLJDT facilitated bacterial clearance by increasing phagocytic activities of peritoneal macrophages. Furthermore, HLJDT treatment reversed CLP-induced suppression of IFN-γ expression and blocked CLP-induced increase in IL-4 expression in spleens of rats at 24 h after CLP, indicating that HLJDT could reverse the shift from Th1 to Th2 response and promote Th1/Th2 balance toward Th1 predominance in septic rats. Moreover, HLJDT also inhibited the expression of IL-17A and ROR-γt in spleens of septic rats, indicating HLJDT is able to inhibit Th17 activation in septic condition. In conclusion, the present study demonstrated the protective effects of HLJDT against sepsis and highlighted the potential of HLJDT as a medication for septic patients.

    Short-chain volatile fatty acids (VFA) and methane are the products from a wide variety of microorganisms living in the gastrointestinal tract. The objective of this study was to examine effects of feedstuff and select nitro compounds on VFA and methane production during in vitro incubation of laying hen cecal contents and rumen fluid from cattle and sheep. In the first experiment, one of the three nitro compound was added to incubations containing cecal contents from laying hens supplemented with either alfalfa (AF) or layer feed (LF). Both feed material influenced VFA production and acetic acid was the primary component. Incubations with nitro ethanol and 2-nitropropanol (NP) had significantly (Pmethane production in the incubations although methane was lower (Pmethane production in incubations of both rumen fluids. The results show that NE impedes methane production, especially in incubations of chicken cecal contents.

    The water exchange (WE) method can decrease the discomfort of the patients undergoing colonoscopy. It also provides salvage cleansing and improves adenoma detection, but a longer intubation time is required. Cap-assisted colonoscopy leads to a significant reduction in cecal intubation time compared with traditional colonoscopy with air insufflation. The aim of this study was to investigate whether combined cap-assisted colonoscopy and water exchange (CWE) could decrease the cecal intubation time compared with WE. A total of 120 patients undergoing fully sedated colonoscopy at a regional hospital in southern Taiwan were randomized to colonoscopy with either CWE (n=59) or WE (n=61). The primary endpoint was cecal intubation time. The mean cecal intubation time was significantly shorter in CWE (12.0 min) compared with WE (14.8 min) (P=0.004). The volume of infused water during insertion was lower in CWE (840 ml) compared with WE (1044 ml) (P=0.003). The adenoma detection rate was 50.8 and 47.5% for CWE and WE, respectively (P=0.472). The Boston Bowel Preparation Scale scores were comparable in the two groups. Results from the multiple linear regression analysis indicated that WE with a cap, a higher degree of endoscopist's experience, a higher Boston Bowel Preparation Scale score, and a lower volume of water infused during insertion, without abdominal compression, without change of position, and without chronic laxative use, were significantly associated with a shorter cecal intubation time. In comparison with WE, CWE could shorten the cecal intubation time and required lower volume of water infusion during insertion without compromising the cleansing effect of WE.

    Full Text Available The aim of the present study was to evaluate the effect of purslane on immune responses and cecal microflora composition of broiler chickens. One hundred forty four day old broiler chicks (Ross 308 were allocated randomly in 3 groups and 4 replicates to receive diets supplemented with 0 (control, 1 and 2 % of dried purslane. At 21 and 35 days of age 1 mL of sheep red blood cell (SRBC injected to 2 broilers of each replicate and blood samples were taken 7 days after each injection. Eight chicks per treatment at the age of 42 d were killed and the number of coliforms, E-Coli and Lactobacillus bacteria populations in ceca were enumerated on appropriate bacteriological media. There were no significant different in primary and secondary antibody titer against SRBC and no different between the treatments for proportional weight of bursa, thymus and spleen. The results of experiment indicated that use of purslane significantly increased Lactobacillus and decreased E-Coli bacteria population. Use of purslane had no effect on coliforms bacteria population. It is concluded that purslane inclusion had a positive significant effect on cecal microflora composition.

    The differential fermentative capacities of microflora from two regions of the large bowel and how fermentation was altered by prior exposure of the microflora to the substrate to be fermented were studied using an in vitro fermentation system. Bacterial inocula were prepared from cecal contents and feces from three groups of rats fed purified diets containing 100 g/kg dietary fiber from canned peas or psyllium seed husk, or a nonpurified diet containing 170 g/kg dietary fiber. The substrate for all fermentations was ileal excreta from colectomized rats fed a purified diet containing 100 g/kg dietary fiber from canned peas. Anaerobic fermentations were conducted for 0, 3, 6, 12, 24, 48 and 96 h. Sugars of the unfermented polysaccharides were measured by gas chromatography following acid hydrolysis; disappearance was the measure of fermentation. Independent of inoculum source, > 90% of the starch and arabinose and 75% of the uronic acids, but peas or nonpurified diet. Bacterial efficiency of carbohydrate utilization, the increase in muramic acid/mole carbohydrate fermented, was greatest (P peas. We conclude that using cecal microflora as the inoculum source provides a more accurate index of fermentation during transit through the large bowel and that noncellulosic and storage polysaccharides of the plant cell wall are utilized before cellulose.

    Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS) qualitatively and quantitatively measured resistant starch (RS) in rat cecal contents. Fisher 344 rats were fed diets of 55% (w/w, dry basis) starch for 8 weeks. Cecal contents were collected from sacrificed rats. A corn starch control was compared against three RS diets. The RS diets were high-amylose corn starch (HA7), HA7 chemically modified with octenyl succinic anhydride, and stearic-acid-complexed HA7 starch. To calibrate the FTIR-PAS analysis, samples from each diet were analyzed using an enzymatic assay. A partial least-squares cross-validation plot generated from the enzymatic assay and FTIR-PAS spectral results for starch fit the ideal curve with a R2 of 0.997. A principal component analysis plot of components 1 and 2 showed that spectra from diets clustered significantly from each other. This study clearly showed that FTIR-PAS can accurately quantify starch content and identify the form of starch in complex matrices.

    Full Text Available The objective of the present study was to evaluate the prebiotic ability of Arkansas (AR LaKast rice bran cultivars as a feed supplement to reduce Salmonella Typhimurium and other gut microbiota. An in vitro mixed anaerobic culture system was used to simulate conditions in the chicken ceca. Anaerobic cultures contained feed, cecal contents collected from 2, 4, and 6 weeks of chicken broilers, and with/without AR rice bran (pureline and hybrid. After 24 h pre-incubation, S. Typhimurium was inoculated into the anaerobic cultures and surviving S. Typhimurium were enumerated during anaerobic incubation up to 48 h. Samples were also collected after 0, 6, 12, 24, 48 h incubation for microbiome analysis with an Illumina MiSeq platform to investigate the changes in bacterial composition. Both pure and hybrid LaKast rice exhibited significant inhibitory effects in all experiments using 2, 4, and 6 weeks ceca but greater bactericidal effects by LaKast rice were observed at 6 weeks compared to 2- and 4-week ceca samples. For samples containing 6-week chicken ceca, the pureline and hybrid rice bran resulted in no viable S. Typhimurium and 6.58 log CFU/ml reduction after 48 h, respectively. Adding rice bran also led to changes in the cecal microbiota. LaKast rice bran resulted in more diverse bacterial population than control groups without any rice bran. The lowest abundance of Proteobacteria (at phylum level and Enterobacteriaceae (at family and genus level was exhibited in LaKast pure treated groups followed by LaKast hybrid and control. This may be attributed to a significant reduction of S. Typhimurium of the Enterobacteriaceae family and Proteobacteria phylum. This study suggests the beneficial functionality of LaKast rice brans as biological supplements in feed. The use of rice bran is favorable for both the consumer and the rice industry because of the perception of rice bran as a naturally occurring substance. As an abundant by-product of rice

    Full Text Available The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chicks per pen. There were four experimental diets containing two different nutrient densities and supplemented with or without essential oils. Experimental period lasted for 35 days. No clear interaction between nutrient density and essential oils on any of growth performance-related parameters was observed. Live body weights were affected (p<0.05 by nutrient density at 21 days and by dietary essential oils at 35 days. Essential oils significantly (p<0.05 increased daily body weight gain and feed conversion ratio during the periods of 22 to 35 and 1 to 35 days, but failed to affect feed intake during the entire experimental period. Daily weight gain at 1 to 21 days and feed intake at 1 to 21 and 1 to 35 days were significantly impaired (p<0.05 by nutrient density. There were significant treatment interactions (p<0.05 on relative weights of bursa of Fabricius and abdominal fat contents. Finally, either essential oil or nutrient density did not influence the relative percentages of breast and leg meats, the population of cecal microflora, blood parameters and antibody titers against Newcastle disease and infectious bronchitis in broiler chickens. It was concluded that dietary essential oils, independent to nutrient density, failed to stimulate feed intake, but increased growth performance in broiler chickens.

    Bile acids (BAs) act as signaling molecules in various physiological processes, and are related to colonic microbiota composition as well as to different types of dietary fat and fiber. This study investigated whether guar gum and pectin-two fibers with distinct functional characteristics-affect BA profiles, microbiota composition, and gut metabolites in rats. Low- (LM) or high-methoxylated (HM) pectin, and low-, medium-, or high-molecular-weight (MW) guar gum were administered to rats that were fed either low- or high-fat diets. Cecal BAs, short-chain fatty acids (SCFA) and microbiota composition, and plasma lipopolysaccharide-binding protein (LBP) levels were analyzed, by using novel methodologies based on gas chromatography (BAs and SCFAs) and 16S rRNA gene sequencing on the Illumina MiSeq platform. Strong correlations were observed between cecal BA and SCFA levels, microbiota composition, and portal plasma LBP levels in rats on a high-fat diet. Notably, guar gum consumption with medium-MW increased the cecal amounts of cholic-, chenodeoxycholic-, and ursodeoxycholic acids as well as α-, β-, and ω-muricholic acids to a greater extent than other types of guar gum or the fiber-free control diet. In contrast, the amounts of cecal deoxycholic- and hyodeoxycholic acid were reduced with all types of guar gum independent of chain length. Differences in BA composition between pectin groups were less obvious, but cecal levels of α- and ω-muricholic acids were higher in rats fed LM as compared to HM pectin or the control diet. The inflammatory marker LBP was downregulated in rats fed medium-MW guar gum and HM pectin; these two fibers decreased the cecal abundance of Oscillospira and an unclassified genus in Ruminococcaceae, and increased that of an unclassified family in RF32. These results indicate that the molecular properties of guar gum and pectin are important for their ability to modulate cecal BA formation, gut microbiota composition, and high-fat diet induced

With the increasing rate of sepsis in the geriatric population, an easy-access animal model for preclinical studies of elderly sepsis is urgently needed. This study investigates whether a sepsis model that is established in D-gal-induced aging rats can serve as a suitable model for preclinical studies of elderly patients with sepsis.Objective: To investigate the acute kidney injury (AKI and inflammatory response of sepsis following cecal ligation and puncture (CLP in D-gal-induced aging rats.Methods: Twelve-week-old male Sprague Dawley rats were divided into low-dose D-gal (L D-gal, 125 mg/kg/d, high-dose D-gal (H D-gal, 500 mg/kg/d, and control groups. After daily subcutaneous injection of D-gal for 6 weeks, the CLP method was used to establish a sepsis model.Results: The mortality was 73.3%, 40%, and 33.3% in the H D-gal, L D-gal, and control groups, respectively. Blood urea nitrogen, creatinine, plasma neutrophil gelatinase-associated lipocalin, interleukin-6, interleukin-10, and tumor necrosis factor-α were markedly increased in the H D-gal group after establishment of the sepsis model (H D-gal vs control, P<0.05 at 12 h and 24 h post-CLP. The rate of severe AKI (RIFLE-F at 24 h post-CLP was 43% for both the control and L D-gal groups and 80% for the H D-gal group.Conclusion: High-dose-D-gal-induced aging rats are

    Full Text Available Safety of either LigaSure or rubber band in closing inflamed appendiceal stump in acute appendicitis has been less investigated. In this study, cecal ligation followed by resecting inflamed cecum was performed to mimic appendectomy in a rat model of acute appendicitis. Rats were sacrificed immediately (Group A and 7 days (Group B after cecal resection, respectively. The cecal stumps were closed by silk ligature (S, 5 mm LigaSure (L, or rubber band (R. Seven days after cecal resection, the LigaSure (BL and silk subgroups (BS had significantly less intra-abdominal adhesion and better laparotomy wound healing than rubber band subgroup (BR. The initial bursting pressure at cecal stump was comparable among the three methods; along with tissue healing process, both BL and BS provided a higher bursting pressure than BR 7 days after appendectomy. BL subgroup had more abundant hydroxyproline deposition than BS and BR subgroup. Furthermore, serum TNF-α in BR group kept persistently increasing along with time after cecal resection. Thus, the finding that LigaSure but not rubber band is safe in sealing off the inflamed cecal stump in rat model of acute appendicitis suggests the possibility of applying LigaSure for appendectomy via single port procedure or natural orifice transluminal endoscopic surgery (NOTES.

    Enterohemorrhagic Escherichia coli O157:H7 (EHEC) is an important food-borne pathogen. While the molecular mechanisms governing E. coli O157:H7 pathogenesis have been intensively investigated, the role of host factors has received less attention. In this study, we tested the hypothesis that the enteric catecholamines norepinephrine (NE) and dopamine (DA) modulate interactions of the cecal mucosa with E. coli O157:H7. Full-thickness sheets of murine cecum were mounted in Ussing chambers and short circuit current and tissue electrical conductance were periodically determined to assess active transepithelial ion transport and ionic permeability, respectively. Neurochemicals and stationary-phase E. coli O157:H7 were exposed respectively to the contraluminal and luminal aspects of the mucosa. Epithelial adherence of E. coli O157:H7 was quantified by a bacterial adhesion assay after 90 min of luminal E. coli O157:H7 exposure. DA and NE increased E. coli O157:H7 adherence relative to untreated control tissues at 50% effective concentrations of 3.8 microM and 4.2 microM respectively. Pretreatment of tissues with either the alpha-adrenergic antagonist phentolamine or the beta-adrenergic antagonist propranolol prevented the action of NE. The effect of DA was prevented by the dopamine antagonist haloperidol. The drugs did not impair tissue viability or transepithelial conductance. The present findings suggest that enteric catecholamines modulate E. coli O157:H7 adherence to the cecal epithelium. Conditions associated with elevated catecholamine release, such as stress exposure, may influence host susceptibility to E. coli O157:H7 infection.

  2. Cecal Ligation and Puncture Results in Long-Term Central Nervous System Myeloid Inflammation.

    Full Text Available Survivors of sepsis often experience long-term cognitive and functional decline. Previous studies utilizing lipopolysaccharide injection and cecal ligation and puncture in rodent models of sepsis have demonstrated changes in depressive-like behavior and learning and memory after sepsis, as well as evidence of myeloid inflammation and cytokine expression in the brain, but the long-term course of neuroinflammation after sepsis remains unclear. Here, we utilize cecal ligation and puncture with greater than 80% survival as a model of sepsis. We found that sepsis survivor mice demonstrate deficits in extinction of conditioned fear, but no acquisition of fear conditioning, nearly two months after sepsis. These cognitive changes occur in the absence of neuronal loss or changes in synaptic density in the hippocampus. Sepsis also resulted in infiltration of monocytes and neutrophils into the CNS at least two weeks after sepsis in a CCR2 independent manner. Cellular inflammation is accompanied by long-term expression of pro-inflammatory cytokine and chemokine genes, including TNFα and CCR2 ligands, in whole brain homogenates. Gene expression analysis of microglia revealed that while microglia do express anti-microbial genes and damage-associated molecular pattern molecules of the S100A family of genes at least 2 weeks after sepsis, they do not express the cytokines observed in whole brain homogenates. Our results indicate that in a naturalistic model of infection, sepsis results in long-term neuroinflammation, and that this sustained inflammation is likely due to interactions among multiple cell types, including resident microglia and peripherally derived myeloid cells.

    Background: The mechanism underlying transient increases in immunoglobulin (Ig) A concentrations in the cecal contents of rats fed fructo-oligosaccharide (FOS) is unclear. Objective: This study was designed to test whether increased IgA concentrations represent one aspect of the inflammatory response to increased permeability induced by FOS in the cecum. Methods: Seven-week-old male Wistar rats were fed a fiber-free semipurified diet (FFP) with or without supplemental FOS (60 g/kg diet) for 9 or 58 d [experiment (expt.) 1], 7 d (expt. 2), or 7 or 56 d (expt. 3). In addition to measuring IgA concentrations in cecal content, we assessed gut permeability, inflammatory responses (expt. 1), the number of IgA plasma cells in the cecal lamina propria, polymeric Ig receptor (pIgR) expression in the cecal mucosa (expt. 2), and the condition of the cecal mucus layer (expt. 3). Results: The cecal IgA concentration in the FOS-fed rats was 15-fold higher than that of the rats fed FFP for 9 d ( P d. These effects were not observed in the rats fed FOS for 58 d (expt. 1). Accompanying the higher cecal IgA concentration, pIgR protein and the number of IgA plasma cells in the cecal mucosa were higher in the FOS-fed rats than in the rats fed FFP for 7 d (expt. 2). Destruction of the mucus layer on the epithelial surface, as evidenced by Alcian blue staining in the cecal sections, was evident in the rats fed FOS for 7 d, but the mucus layer appeared normal in the rats fed FOS for 56 d (expt. 3). Conclusions: These findings suggest that transient increases in cecal IgA concentrations induced by FOS in rats are associated with mucosal inflammation in response to increased gut permeability; these are presumably evoked by disruption of the cecal mucus barrier. The observed responses could contribute to the maturation of the gut immune system. © 2017 American Society for Nutrition.

    Full Text Available Abstract Background Salmonellosis is one of the most important bacterial food borne illnesses worldwide. A major source of infection for humans is consumption of chicken or egg products that have been contaminated with Salmonella enterica serotype Typhimurium, however our knowledge regarding colonization and persistence factors in the chicken is small. Results We compared intestinal and systemic colonization of 1-week-old White Leghorn chicks and Salmonella-resistant CBA/J mice during infection with Salmonella enterica serotype Typhimurium ATCC14028, one of the most commonly studied isolates. We also studied the distribution of wild type serotype Typhimurium ATCC14028 and an isogenic invA mutant during competitive infection in the cecum of 1-week-old White Leghorn chicks and 8-week-old CBA/J mice. We found that although the systemic levels of serotype Typhimurium in both infected animal models are low, infected mice have significant splenomegaly beginning at 15 days post infection. In the intestinal tract itself, the cecal contents are the major site for recovery of serotype Typhimurium in the cecum of 1-week-old chicks and Salmonella-resistant mice. Additionally we show that only a small minority of Salmonellae are intracellular in the cecal epithelium of both infected animal models, and while SPI-1 is important for successful infection in the murine model, it is important for association with the cecal epithelium of 1-week-old chicks. Finally, we show that in chicks infected with serotype Typhimurium at 1 week of age, the level of fecal shedding of this organism does not reflect the level of cecal colonization as it does in murine models. Conclusion In our study, we highlight important differences in systemic and intestinal colonization levels between chick and murine serotype Typhimurium infections, and provide evidence that suggests that the role of SPI-1 may not be the same during colonization of both animal models.

    There is an increasing movement against use of antibiotic growth promoters in animal feed. Prebiotic supplementation is a potential alternative to enhance the host's natural defense through modulation of gut microbiota. In the present study, the effect of mannan oligosaccharide (MOS) and virginiamycin (VIRG) on cecal microbial ecology and intestinal morphology of broiler chickens raised under suboptimal conditions was evaluated. MOS and VIRG induced different bacterial community structures, as revealed by denaturing gradient gel electrophoresis of 16S rDNA. The antibiotic treatment reduced cecal microbial diversity while the community equitability increased. A higher bacterial diversity was observed in the cecum of MOS-supplemented birds. Quantitative polymerase chain reaction results indicated that MOS changed the cecal microbiota in favor of the Firmicutes population but not the Bacteroidetes population. No difference was observed in total bacterial counts among treatments. MOS promoted the growth of Lactobacillus spp. and Bifidobacterium spp. in the cecum and increased villus height and goblet cell numbers in the ileum and jejunum. These results provide a deeper insight into the microbial ecological changes after supplementation of MOS prebiotic in poultry diets.

    2014-10-01

    Full Text Available Introduction: Carcinoid tumors are neuroendocrine malignancies that originate in the neuroectodermal cells of the Amine, Peptide Uptake and Decarboxylation system dispersed in the gastrointestinal mucosa and representing about 80–88% of tumors of cecal appendix. These are tumors usually diagnosed at appendectomies, and it is estimated that from each 100 appendectomies yearly performed, at least one case is a neuroendocrine tumor. Objectives: To report the experience of an University Teaching Hospital in health and reference at the east side of São Paulo and great São Paulo in cases of these rare appendicular tumors, with emphasis on the importance of these descriptions, as probably are rare those surgeons in particular who will acquire extensive wisdom in these cases. Method: Retrospective analysis of 237 patients who underwent appendectomy from September 2010 to September 2012 in the Hospital Santa Marcelina-SP. We evaluated data on age, gender, initial clinical presentation and surgical findings of patients undergoing appendectomy with subsequent anatomic and immunopathological diagnosis of carcinoid tumor of cecal appendix. Results: The presence of a carcinoid tumor of the appendix was observed in 5 patients, which corresponds to 2.1% of all appendectomies performed. Regarding gender, 4 patients (80% were female and the average age was 34.2 years, with a range from 17 to 68 years. In all patients the initial hypothesis for surgery indication was acute appendicitis, with an intraoperative finding of necroperforated phase acute appendicitis in 3 patients (60%. Conclusion: The therapeutical conduct after the diagnosis of carcinoid tumors of the appendix must be based on the data provided by pathological and immunohistochemical studies, besides the judicious judgment of the attending physician.

    Sepsis is a potentially lethal condition, and it is associated with platelet alterations. The present study sought to investigate the activity of ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase), E-5'-nucleotidase, and ecto-adenosine deaminase (E-ADA) in the platelets of rats that were induced with sepsis. Male Wistar rats were divided into three groups of ten animals each: a negative control group (normal; NC); a group that underwent surgical procedures (sham); and a group that underwent cecal ligation and perforation (CLP). The induction of sepsis was confirmed by bacteremia, and the causative pathogen identified was Escherichia coli. Hematological parameters showed leukocytosis and thrombocytopenia in animals in the septic group. The results also revealed that there were significant (p CLP group compared to the sham and control groups. Conversely, ADP hydrolysis was significantly decreased (p CLP group compared to the sham and control groups. Purine levels were analyzed by high-performance liquid chromatography (HPLC) in serum samples from control, sham, and CLP groups. Increased concentrations of ATP, adenosine, and inosine were found in the CLP group compared to the sham and control groups. Conversely, the concentrations of ADP and AMP in the CPL group were not significantly altered. We suggest that alterations in hematological parameters, nucleotide hydrolysis in platelets, and nucleotide concentrations in serum samples of rats with induced sepsis may be related to thromboembolic events.

    Hydrogen sulfide (H2S) is an endogenously produced gaseous messenger that participates in regulation of cardiovascular functions. This study evaluates the possible protective effect of H2S in cardiovascular dysfunction induced by cecal ligation and puncture (CLP) in rats. After 24 h of induction of CLP, heart rate (HR), mortality, cardiac and inflammation biomarkers (creatine kinase-MB (CK-MB) isozyme, cardiac troponin I (cTnI), C-reactive protein (CRP), and lactate dehydrogenase (LDH)), in vitro vascular reactivity, histopathological examination, and oxidative biomarkers (malondialdehyde (MDA), reduced glutathione (GSH), and superoxide dismutase (SOD)) were determined. CLP induced elevations in HR, mortality, serum CK-MB, cTnI, CRP, and LDH, in addition to impaired aortic contraction to potassium chloride and phenylephrine and relaxation to acetylcholine without affecting sodium nitroprusside responses. Moreover, CLP increased cardiac and aortic MDA and decreased SOD, without affecting GSH and caused a marked subserosal and interstitial inflammation in endocardium. Sodium hydrosulfide, but not the irreversible inhibitor of H2S synthesis dl-propargyl glycine, protected against CLP-induced changes in HR, mortality, cardiac and inflammatory biomarkers, oxidative stress, and myocardium histopathological changes without affecting vascular dysfunction. Our results confirm that H2S can attenuate CLP-induced cardiac, but not vascular, dysfunction possibly through its anti-inflammatory and antioxidant effects. © The Author(s) 2015.

    This study aimed at comparing various diets predicted to induce different stimulations of the cecal microbial activity of the young rabbit fed ad libitum from 16 to 70 d of age: i) a diet enriched with rapidly fermentable fiber expected to stimulate the cecal microbial activity (RFF group); ii) a control diet with a standard composition (C group); iii) and the same control diet with tiamulin and apramycin antibiotics, expected to inhibit the microbial activity (C+AB group). A total of 398 rabbits were used from 42 litters and weaned at 28 d of age. An in vivo digestibility trial was performed on 36 rabbits of 42 to 46 d of age housed in individual metabolic cages. The feed intake and growth rates were lower in the RFF group compared with the C+AB group (-15% in ADFI and -11% in ADG, Psoluble fiber (total dietary fiber minus NDF) was greater for the RFF group. The C+AB diet had a positive effect on the postweaning morbidity rate (P<0.05) but did not affect the mortality rate and the health risk index (morbidity and mortality). Conversely, the RFF diet appeared to reduce the mortality rate compared with the C+AB diet, especially before 41 d of age. Concerning the cecal microbial activity, a supply of RFF in the diet increased the cecal VFA concentrations (+28% vs. C+AB and +22% vs. C, P<0.001) and lowered the pH. The VFA pattern was affected at 45 and 60 d, with a dominance of acetate in the RFF group (+4% vs. C+AB and C groups, P<0.001) instead of butyrate in the C+AB and C groups (-3.6% and -5% vs. C+AB and C, respectively, P<0.001). Antibiotics addition (C+AB group) reduced the VFA concentration, but only after weaning (-25% at 45 d of age) without changing the fermentation pattern. In conclusion, early intake of RFF in young rabbits stimulated the cecal microbial activity, and reduced the voluntary feed intake, leading to a reduced G:F ratio.

    The probiotic function to impact human health is thought to be related to their ability to alter the composition of the gut microbiota and modulate the human innate immune system. The ability to function as a probiotic is believed to be strain specific. Strains of Lactobacillus casei are commonly utilized as probiotics that when consumed alter the composition of the gut microbiota and modulate the host immune response. L. casei strains are known to differ significantly in gene content. The objective of this study was to investigate seven different L. casei strains for their ability to alter the murine gut microbiota and modulate the murine immune system. C57BL/6 mice were fed L. casei strains at a dose of 108 CFU/day/mouse for seven days and sacrificed 3.5h after the last administration. The cecal content and the ileum tissue were collected for microbiota analysis and immune profiling, respectively. While 5 of the L. casei strains altered the gut microbiota in a strain specific manner, two of the strains did not alter the overall cecal microbiota composition. The observed changes cluster into three groups containing between 1 and 2 strains. Two strains that did not affect the gut microbiota composition cluster together with the control in their impact on pattern recognition receptors (PRRs) expression, suggesting that the ability to alter the cecal microbiota correlates with the ability to alter PRR expression. They also cluster together in their impact on the expression of intestinal antimicrobial peptides (AMPs). This result suggests that a relationship exists between the capability of a L. casei strains to alter the composition of the gut microbiota, PRR regulation, and AMP regulation.

    Clostridium perfringens can induce necrotic enteritis of chickens, which causes large economic losses every year. Bacillus licheniformis, a probiotic, can inhibit the growth of pathogenic bacteria such as Clostridium perfringens, thereby improving the health status of chickens. However, from a microbial ecology perspective, the mechanisms by which alterations to the gut microbiota improve health remain unknown. In this study, we used Illumina MiSeq sequencing to investigate the cecal microbiota of a negative control group (NC), a C. perfringens and Eimeria challenge group with fishmeal supplementation (PC), a group supplemented with fishmeal and infected with coccidia (FC), and group PC with B. licheniformis supplementation (BL). We found that the health status of C. perfringens-challenged chickens was compromised, and that B. licheniformis improved the growth of the chickens challenged with pathogens. Microbial diversity analysis and taxonomic profiling of groups NC, PC, and FC revealed a disturbed cecal microflora of the birds with C. perfringens. We also characterized the microbiota of the chickens in the BL group using several methods. Principal coordinate analysis demonstrated that, compared with group PC, the bacterial community structure of group BL was more similar to that of group NC. Linear discriminant analysis with effect size revealed less differentially represented bacterial taxa between groups BL and NC than between groups PC and NC. In addition, groups BL and NC appeared to have similar overrepresented microbial taxa (such as Bacteroides, Helicobacter, Megamonas, and Akkermansia) compared with group PC. Finally, a phylogenetic investigation of communities by reconstruction of unobserved states analysis indicated that large differences existed between group PC and groups NC and BL. In conclusion, pre-treatment with B. licheniformis reduced the disturbance of the cecal microbiome induced by challenge with C. perfringens and other factors in broiler

Patients and methods: Items investigated were sex, age, body mass index (BMI, waist circumference, hypertension, diabetes, hyperlipidemia, history of abdominal surgery (excluding colectomy, colon diverticulosis, prescription of antithrombotic agents, and quality of bowel preparation. Expert physicians were defined as those with at least 9 years of endoscopy experience; all other physicians were defined as being in training. In a retrospective analysis, cases in which a physician in training reached the cecum within 15 minutes without requiring the involvement of the supervising physician were defined as eligible cases over which a physician in training should preside, while other cases were defined as non-eligible. Results: Overall, 813 CS cases were analyzed. Males (P<0.0001, cases started by an expert physician (P<0.0001, cases of no fellow physician involvement (P<0.0001, and cases with good bowel preparation (P<0.0001 had significantly shorter cecal intubation times. Of the 562 cases presided over by a physician in training, 194 were deemed eligible and 368 non-eligible. The eligible cases had a higher proportion of males (P=0.017, younger age (P=0.033, higher BMI (P=0.034, and higher rates of hypertension (P=0.001 and good bowel preparation (P=0.001.

    Full Text Available Abstract Background Obese patients display an exaggerated morbidity during sepsis. Since consumption of a western-style diet (WD is a major factor for obesity in the United States, the purpose of the present study was to examine the influence of chronic WD consumption on hepatic inflammation in mice made septic via cecal ligation and puncture (CLP. Feeding mice diets high in fat has been shown to enhance evidence of TLR signaling and this pathway also mediates the hepatic response to invading bacteria. Therefore, we hypothesized that the combined effects of sepsis and feeding WD on TRL-4 signaling would exacerbate hepatic inflammation. Male C57BL/6 mice were fed purified control diet (CD or WD that was enriched in butter fat (34.4% of calories for 3 weeks prior to CLP. Intravital microscopy was used to evaluate leukocyte adhesion in the hepatic microcirculation. To demonstrate the direct effect of saturated fatty acid on hepatocytes, C3A human hepatocytes were cultured in medium containing 100 μM palmitic acid (PA. Quantitative real-time PCR was used to assess mRNA expression of tumor necrosis factor-alpha (TNF-α, monocyte chemotactic protein-1 (MCP-1, intercellular adhesion molecule-1 (ICAM-1, toll-like receptor-4 (TLR-4 and interleukin-8 (IL-8. Results Feeding WD increased firm adhesion of leukocytes in the sinusoids and terminal hepatic venules by 8-fold six hours after CLP; the increase in platelet adhesion was similar to the response observed with leukocytes. Adhesion was accompanied by enhanced expression of TNF-α, MCP-1 and ICAM-1. Messenger RNA expression of TLR-4 was also exacerbated in the WD+CLP group. Exposure of C3A cells to PA up-regulated IL-8 and TLR-4 expression. In addition, PA stimulated the static adhesion of U937 monocytes to C3A cells, a phenomenon blocked by inclusion of an anti-TLR-4/MD2 antibody in the culture medium. Conclusions These findings indicate a link between obesity-enhanced susceptibility to sepsis and

    To identify the factors influencing cecal insertion time (CIT) and to evaluate the effect of obesity indices on CIT. We retrospectively reviewed the data for participants who received both colonoscopy and abdominal computed tomography (CT) from February 2008 to May 2008 as part of a comprehensive health screening program. Age, gender, obesity indices [body mass index (BMI), waist-to-hip circumference ratio (WHR), waist circumference (WC), visceral adipose tissue (VAT) volume and subcutaneous adipose tissue (SAT) volume on abdominal CT], history of prior abdominal surgery, constipation, experience of the colonoscopist, quality of bowel preparation, diverticulosis and time required to reach the cecum were analyzed. CIT was categorized as longer than 10 min (prolonged CIT) and shorter than or equal to 10 min, and then the factors that required a CIT longer than 10 min were examined. A total of 1678 participants were enrolled. The mean age was 50.42 ± 9.931 years and 60.3% were men. The mean BMI, WHR, WC, VAT volume and SAT volume were 23.92 ± 2.964 kg/m 2 , 0.90 ± 0.076, 86.95 ± 8.030 cm, 905.29 ± 475.220 cm 3 and 1707.72 ± 576.550 cm 3 , respectively. The number of patients who underwent abdominal surgery was 268 (16.0%). Colonoscopy was performed by an attending physician alone in 61.9% of cases and with the involvement of a fellow in 38.1% of cases. The median CIT was 7 min (range 2-56 min, IQR 5-10 min), and mean CIT was 8.58 ± 5.291 min. Being female, BMI, VAT volume and involvement of fellow were significantly associated with a prolonged CIT in univariable analysis. In multivariable analysis, being female (OR = 1.29, P = 0.047), lower BMI (< 23 kg/m 2 ) (OR = 1.62, P = 0.004) or higher BMI (≥ 25 kg/m 2 ) (OR = 1.80, P < 0.001), low VAT volume (< 500 cm 3 ) (OR = 1.50, P = 0.013) and fellow involvement (OR = 1.73, P < 0.001) were significant predictors of prolonged CIT. In subgroup analyses for gender, lower BMI or higher BMI and fellow involvement were

    Cecal ligation and puncture (CLP)-induced sepsis is a serious medical condition, caused by a severe systemic infection resulting in a systemic inflammatory response. Recent studies have suggested the therapeutic potential of donors of hydrogen sulfide (H2S), a novel endogenous gasotransmitter and biological mediator in various diseases. The aim of the present study was to assess the effect of H2S supplementation in sepsis, with special reference to its effect on the modulation of regional blood flow. We infused sodium hydrosulfide (NaHS), a compound that produces H2S in aqueous solution (1, 3, or 10 mg/kg/h, for 1 h at each dose level) in control rats or rats 24 h after CLP, and measured blood flow using fluorescent microspheres. In normal control animals, NaHS induced a characteristic redistribution of blood flow, and reduced cardiac, hepatic, and renal blood flow in a dose-dependent fashion. In contrast, in rats subjected to CLP, cardiac, hepatic, and renal blood flow was significantly reduced; infusion of NaHS (1 mg/kg/h and 3 mg/kg/h) significantly increased organ blood flow. In other words, the effect of H2S on regional blood flow is dependent on the status of the animals (i.e., a decrease in blood flow in normal controls, but an increase in blood flow in CLP). We have also evaluated the effect of delayed treatment with NaHS on organ dysfunction and the inflammatory response by treating the animals with NaHS (3 mg/kg) intraperitoneally (i.p.) at 24 h after the start of the CLP procedure; plasma levels of various cytokines and tissue indicators of inflammatory cell infiltration and oxidative stress were measured 6 h later. After 24 h of CLP, glomerular function was significantly impaired, as evidenced by markedly increased (over 4-fold over baseline) blood urea nitrogen and creatinine levels; this increase was also significantly reduced by treatment with NaHS. NaHS also attenuated the CLP-induced increases in malondialdehyde levels (an index of

A Peutz–Jeghers polyp (PJP in a patient without pigmentation or a family history of the disease is called an isolated or solitary PJP. Individuals with PJS carry a very high risk of developing gastrointestinal (GI as well as extra-GI malignancies. This case report documents lesion multiplicity and their malignant potential in a young patient with PJS presenting in a serious condition for the first time.Case report: An 18-year-old female Egyptian patient was admitted with hematochezia and remarkable anemia. After appropriate resuscitation and consent, colonoscopic evaluation revealed seven pedunculated colonic polyps at the ascending and the transverse colon, and numerous variable-sized sessile polyps were scattered all over the colon. To establish hemostasis, endoscopic polypectomy for pedunculated polyps and argon plasma photocoagulation for the bleeding sessile polyps were performed. Histopathological examination revealed cecal adenocarcinoma in one specimen and two simultaneous in situ carcinoma at the transverse and the sigmoid colon in the mucosae of the excised histologically proven hamartomatous polyps. Additionally, one focal in situ carcinoma in the resected colon was detected.Conclusions: When considering the family history, serious GI neoplastic lesions may be unmasked in young patients with PJS who present with hematochezia, even in the absence of its characteristic mucocutaneous pigmented lesions. GI endoscopic surveillance programs should be adopted for diagnosed cases of PJS and their families. Genetic prenatal screening for early detection is the best option for

    The std operon encodes a fimbrial adhesin of Salmonella enterica serotype Typhimurium that is required for attachment to intestinal epithelial cells and for cecal colonization in the mouse. To study the mechanism by which this virulence factor contributes to colonization we characterized its binding specificity. Std-mediated binding to human colonic epithelial (Caco-2) cells could be abrogated by removing N-linked glycans. Adherence of Std fimbriated S. Typhimurium to Caco-2 cells could be blocked by co-incubation with H type 2 oligosaccharide (Fucalpha1-2Galbeta1-4GlcNAc) or by pretreatment of cells with alpha1-2 fucosidase. In contrast, pretreatment of Caco-2 cells with neuraminidase or co-incubation with the type 2 disaccharide precursor (Galbeta1-4GlcNAc) did not reduce adherence of Std fimbriated S. Typhimurium. Binding of purified Std fimbriae to Fucalpha1-2Galbeta1-4GlcNAc in a solid phase binding assay was competitively inhibited by Ulex europaeus agglutinin-I (UEA-I), a lectin specific for Fucalpha1-2 moieties. Purified Std fimbriae and UEA both bound to a receptor localized in the mucus layer of the murine cecum. These data suggest that the std operon encodes an adhesin that binds an alpha1-2 fucosylated receptor(s) present in the cecal mucosa.

    Full Text Available The objective of this experiment was to evaluate the effect of different rates of propolis alcoholic extract (PAE on the weight gain, carcass traits and cecal pH of growing rabbits. Forty White New Zealand rabbits were distributed in a completely randomized experimental design consisting of four treatments and ten replicates per treatment. The rabbits were allocated individually in wire cages containing a nipple drinker and a semi-automatic feeder. The treatments were: T1 = control, T2 = 1ml of ethanol, T3 = 0.8ml of PAE, and T4 = 1.5ml of PAE. Commercial feed and water were provided ad libitum to the animals, and the treatment with cereal alcohol and PAE was administered orally using a 2ml syringe. It was concluded that the addition of PAE to the rabbits’ feeding resulted in weight gain, carcass traits and cecal pH similar to those of animals which received the diets with ethanol without any addition, except for the paw weight, that was higher in the rabbits which were given PAE, and for the gastric system, that had a higher weight in the rabbits which received no addition to their diet.

    Foods naturally high in dietary fiber are generally considered to protect against development of colorectal cancer (CRC). However, the intrinsic effect of dietary fiber on intestinal carcinogenesis is unclear. We used azoxymethane (AOM) treated A/J Min/+ mice, which developed a significantly higher tumor load in the colon than in the small intestine, to compare the effects of dietary inulin (IN), cellulose (CE) or brewers spent grain (BSG) on intestinal tumorigenesis and cecal microbiota. Each fiber was tested at two dose levels, 5% and 15% (w/w) content of the AIN-93M diet. The microbiota was investigated by next-generation sequencing of the 16S rRNA gene (V4). We found that mice fed IN had approximately 50% lower colonic tumor load than mice fed CE or BSG (pBSG. The Bacteroidetes/Firmicutes ratio was significantly (p = 0.003) different between the three fiber diets with a higher mean value in IN fed mice compared with BSG and CE. We also found a relation between microbiota and the colonic tumor load, where many of the operational taxonomic units (OTUs) related to low tumor load were significantly enriched in mice fed IN. Among the OTUs related to low tumor load were bacteria affiliated with the Bacteroides genus. These results suggest that type of dietary fiber may play a role in the development of CRC, and that the suppressive effect of IN on colonic tumorigenesis is associated with profound changes in the cecal microbiota profile.

    An experiment with 288 male (Ross 308) 1-d-old broilers was conducted to test the hypothesis that a coarse diet supplemented with butyric acid (BA) and fermentable carbohydrates (FC) improves performance of broilers with a poorly digestible protein source. The interaction effects of diet structure (fine or coarse), FC supplementation (with or without), and BA supplementation (with or without) in a poorly digestible diet based on rapeseed meal (RSM) were tested in a factorial arrangement of 8 (2×2×2) dietary treatments. The coarseness of the diet affected feed intake (FI) (PFermentable carbohydrate supplementation did not influence growth performance, gut development, or contents of total BCFA and total biogenic amines in the cecal digesta (P>0.05). Supplementation with FC, however, decreased the cecal concentration of spermine by approximately 31% compared with broilers fed diets without FC (P=0.002). In conclusion, feeding a coarse diet supplemented with BA improved performance of broilers fed a diet containing a poorly digestible protein source. The negative effects of a poorly digestible protein source can thus be partly counterbalanced by coarse grinding and BA supplementation in the diet. © The Author 2015.

    Colonoscopy outcome is limited by endoscope looping, which leads to patient discomfort, prolonged procedure, and increased sedation requirement. Traditional manual abdominal pressure is imprecise and manually intensive. A hands-free abdominal compression device (ACD) may improve colonoscopy outcome. We aimed to assess the effect of a novel ACD on colonoscopy outcomes compared to manual pressure. This was a prospective single-blinded study of patients undergoing outpatient colonoscopy. The ACD (N-Doe Pillow™) was applied on 50 consecutive patients. Endoscopists were blinded to device usage. Control cases using manual pressure were randomly selected in a 2:1 manner. Primary outcome was cecal intubation time. Secondary outcomes included sedation requirement and complications. Subgroup analyses evaluated ACD effect on endoscopists with different experiences and patients at higher risk of difficult colonoscopy. Fisher's exact and Student's t-tests were performed for univariate analyses. Multivariate analysis was performed using generalized linear regression. Fifty patients undergoing colonoscopy with ACD assistance were compared to 100 matched controls. Mean cecal intubation time was significantly reduced in the ACD group compared to controls (6.38 minutes versus 11.8 minutes, P ACD use was independently associated with reduction in cecal intubation time (β-coeff: -4.11, P = .007). Subgroup analyses revealed a trend toward increased improvement in cecal intubation time among junior endoscopists and obese patients. A novel, hands-free ACD significantly decreased cecal intubation time in this prospective, single-blinded, match-controlled study. A trend toward more improvement was seen among junior faculty, suggesting an application for trainees and/or endoscopists with smaller case volumes.

    The objective of this 49-d experiment was to test effects of cecal oxytetracycline (OTC) infusion, and dietary avidin and biotin supplementation on the biotin status of nongravid gilts. Twenty-eight crossbred gilts with an initial age of 160 d and BW of 120 kg were surgically fitted with a T-cannula in the terminal ileum, a cecal fistula, and an indwelling catheter in the anterior vena cava, and allotted to 7 dietary treatments. Treatments with the basal semipurified (SP) diet fed at 1.86 kg/d were: SP-1, negative control; SP-2, positive control with 270 μg of biotin/kg; SP-3, with spray-dried egg albumen (EA, 100 g/d) and OTC (2.56 g/d by cecal infusion); and SP-4, with EA, OTC, and 700 μg of biotin/kg. Treatments with the basal corn-soybean meal (CS) diet fed at 1.80 kg/d were: CS-1, negative control; CS-2, with EA and OTC; and CS-3, with EA, OTC, and 700 μg of biotin/kg. Response criteria were: fecal bacteria counts; plasma concentrations of biotin, glucose, and urea N (PUN); liver pyruvate carboxylase (PC) activity; kidney and epithelial tissue histology; ileal and fecal biotin concentrations; ileal and total tract N and energy utilization; daily gilt observation; and BW gain. Blood samples were collected every 7 d with serial samples collected on d 49. Total urine collections and fecal grab samples were made twice daily from d 44 to 49. Gilts were killed on d 50 and liver, kidney, and skin samples were collected. No gilts had symptoms of biotin deficiency. There were no treatment differences in BW gain, plasma glucose concentrations, liver PC activity, kidney and epithelial tissue histology, or fecal bacteria counts. Ileal and total tract N and energy digestibilities (%) did not differ among treatments within the same protein source, with greater (P ≤ 0.05) values for gilts on the SP treatments than the CS treatments. However, N retained/N absorbed and N retained/N intake (%) were less (P ≤ 0.05) and PUN concentrations were greater (P ≤ 0.05) for SP

    Full Text Available Low-molecular-weight chitosan (LC promoted growth in weaned piglets as an alternative to feed-grade antibiotics. To investigate the influence of LC supplementation on piglets' gut microbiome and compare the differences in community composition between LC and antibiotics with ZnO addition, we assessed the cecal microbial community by 16S rRNA gene sequencing with three treatments consisting of basal diet (CTR group, basal diet with low-molecular-weight chitosan (LC group, and basal diet with antibiotic and ZnO (AZ group. LC decreased pH more than AZ did in the cecum (both compared to CTR. Beta diversity analysis showed that community structure was distinctly different among the CTR, LC, and AZ treatments, indicating that either LC or AZ treatment modulated the piglet microbiota. Bacteroidetes, Firmicutes, and Proteobacteria dominated the community [>98% of operational taxonomic units (OTUs] in piglet cecal contents. Compared to CTR, both LC, and AZ increased the relative abundance of Bacteroidetes while they decreased the count of Firmicutes and AZ decreased the population of Proteobacteria. In CTR the top four abundant genera were Prevotella (~10.4%, Succinivibrio (~6.2%, Lactobacillus (~5.6%, and Anaerovibrio (5.4%. Both LC and AZ increased the relative abundance of Prevotella but decreased the ratio of Lactobacillus when they compared with CTR. Moreover, LC increased the relative abundance of Succinivibrio and Anaerovibrio while AZ decreased them. The microbial function prediction showed LC enriched more pathways in the metabolism of cofactors and vitamins than CTR or AZ did. LC may potentially function as an alternative to feed-grade antibiotics in weaned piglets due to its beneficial regulation of the intestinal microbiome.

    The present study aimed to document quantitatively and qualitatively the contamination by thermotolerant Campylobacter spp. of turkey samples during slaughtering. Four Campylobacter-positive turkey flocks were investigated at the slaughterhouse at three different stages: evisceration (cecal content), after carcass rinses but before chilling (neck skin), and after breast meat cut (meat). In each case, the studied flock was slaughtered first thing in the morning any given day of the week. The efficiency of cleaning and disinfecting operations was examined in the facility prior to processing the studied flock. For each flock, 90 samples were collected from cecal contents, neck skins, and meat pieces and checked quantitatively and qualitatively for Campylobacter. Identification of Campylobacter species was determined by PCR, and genetic patterns were determined by pulsed-field gel electrophoresis. Campylobacter contamination levels of ceca range from 2 to more than 7 Log CFU/g, while those of neck skin range from 0.5 to 3.5 Log CFU/g and those of meat range from 0.1 to 1.9 Log CFU/g. These differences in Campylobacter counts were not associated with a modification of Campylobacter species ratio; however, in the Campylobacter jejuni population, four genetic groups identified from the ceca were not recovered during slaughtering operations and two other genetic groups were only detected after chilling at the cutting stage of the breast meat. The present study suggests that the slaughtering process did not affect Campylobacter species populations; however, it might have influenced the strain population. Finally, the Campylobacter populations found on breast meat were similar to those isolated from the digestive tract of the birds.

    This experiment was conducted to investigate the effects of Bacillus amyloliquefaciens probiotic (BAP) as a direct-fed microbial on growth performance, cecal microflora, serum immunoglobulin levels, and fecal noxious gas emissions of broiler chickens. A total of 400 one-day-old broiler chicks (Ross 308) were randomly assigned to 1 of 5 treatment diets formulated to supply 0, 1, 5, 10, and 20 g/kg of BAP and were fed for 35 d. Each treatment had 8 replicate pens with 10 birds per replicate. On completion of the growth trial, fecal samples were collected, and ammonia (NH3) and hydrogen sulfide (H2S) emissions were measured. Increasing concentration of BAP had positive linear effect on the ADG of broilers (P Bacillus content, but exerted negative linear effect on cecal Escherichia coli (P Bacillus amyloliquefaciens could be suggested as a potential feed additive of broiler diets. © Poultry Science Association Inc.

    Full Text Available The present study was conducted to evaluate the effect of the dietary supplementation of Bacillus amyloliquefaciens-based direct-fed microbial (DFM on growth performance, nutrient utilization, intestinal morphology and cecal microflora in broiler chickens. A total of two hundred and eighty eight 1-d-old Arbor Acres male broilers were randomly allocated to one of four experimental treatments in a completely randomized design. Each treatment was fed to eight replicate cages, with nine birds per cage. Dietary treatments were composed of an antibiotic-free basal diet (control, and the basal diet supplemented with either 15 mg/kg of virginiamycin as antibiotic growth promoter (AGP, 30 mg/kg of Bacillus amyloliquefaciens-based DFM (DFM 30 or 60 mg/kg of Bacillus amyloliquefaciens-based DFM (DFM 60. Experimental diets were fed in two phases: starter (d 1 to 21 and finisher (d 22 to 42. Growth performance, nutrient utilization, morphological parameters of the small intestine and cecal microbial populations were measured at the end of the starter (d 21 and finisher (d 42 phases. During the starter phase, DFM and virginiamycin supplementation improved the feed conversion ratio (FCR; p<0.01 compared with the control group. For the finisher phase and the overall experiment (d 1 to 42 broilers fed diets with the DFM had better body weight gain (BWG and FCR than that of control (p<0.05. Supplementation of virginiamycin and DFM significantly increased the total tract apparent digestibility of crude protein (CP, dry matter (DM and gross energy during both starter and finisher phases (p<0.05 compared with the control group. On d 21, villus height, crypt depth and villus height to crypt depth ratio of duodenum, jejunum, and ileum were significantly increased for the birds fed with the DFM diets as compared with the control group (p<0.05. The DFM 30, DFM 60, and AGP groups decreased the Escherichia coli population in cecum at d 21 and d 42 compared with control

    Full Text Available Aflatoxin B1 (AFB1 is the most toxic form among the mycotoxins. Cytokines are important mediators of the immune system. T-cell subsets play a crucial role in cell-mediated immunity. The aim of present study was to evaluate the effects of dietary AFB1 on the cytokines expression and T-cell subsets in the cecal tonsil of broiler chickens throughout a 21-day experimental period. One hundred and fifty six one-day-old broiler chickens were randomly divided into control group (0 mg AFB1/kg feed and AFB1 group (0.6 mg pure AFB1/kg feed. At 7, 14 and 21 days of age, the levels of seven cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, IFN-γ and TNF-α mRNA expression as well as the proportions of T-cell subsets (CD3+, CD3+CD4+, CD3+CD8+ by qRT-PCR and flow cytometry methods were assessed in the cecal tonsils. The levels of the seven cytokines mRNA expression and the percentages of T-cell subsets significantly decreased at 14 and 21 days of age in the AFB1 group compared with the control group. However, the CD4+/CD8+ ratio was not significantly changed. These results demonstrate that 0.6 mg/kg AFB1 dietary exposure reduced the levels of cytokines mRNA expression and the percentages of T-cell subsets in the cecal tonsils of broiler chickens, suggesting that the cell-mediated immunity of cecal tonsils might be impaired in broilers.

    Monogastric herbivores such as the guinea pig depend on energy supply from enteric fermentation as short-chain fatty acids (SCFA) corresponding to 30-40% of their maintenance energy requirements. They evolved specific digestive system to adapt their indigenous microflora to plant polysaccharides fermentation. No information has been available about the adaptability of microbial fermentation in hindgut of the monogastric herbivorous to an animal protein diet. We investigated if the guinea pig can fully retrieve energy of an animal protein diet by hindgut fermentation compared with a plant protein diet. For comparison, we also studied two omnivores. End products of in vitro cecal fermentation (SCFA, ammonia and gases) were measured to judge how well an animal protein diet could be fermented. The animal protein diet resulted in the less intensive fermentation with increased feed intake and volume of cecal contents than the plant protein diet only in guinea pigs. This may be due to a limited capacity of the hindgut microflora to adapt to the substrate rich in animal protein. We also found that chick cecal contents produced methane at higher emission rate than ruminants.

    The effects of bacterial collection site, bacterial adaption to substrate and duration of fermentation on short-chain fatty acid (SCFA) production were studied using an in vitro fermentation system. Cecal and fecal inocula from rats fed purified diets containing 100 g/kg dietary fiber from canned peas or psyllium seed husk, or a nonpurified diet containing 170 g/kg dietary fiber fermented ileal excreta from colectomized rats fed a purified diet containing 100 g/kg dietary fiber from canned peas. The SCFA concentration, measured by gas chromatography, in anaerobic fermentations of 0, 3, 6, 12, 24, 48, 72 and 96 h, increased (P pea or nonpurified diets produced SCFA at greater (P < 0.05) molar proportions as acetate and less (P < 0.05) as propionate than inocula from rats fed psyllium seed husk at most time points. We conclude that collection site, adaptation of bacteria to the substrate to be fermented and duration of fermentation significantly influence the results of in vitro fermentation studies.

    Full Text Available Feed efficiency (FE appears to vary even within closely related pigs, and may be partly affected by the diversity in the composition and function of gut microbes. To investigate the components and functional differences of gut microbiota of low and high FE pigs, high throughput sequencing and de novo metagenomics were performed on pig cecal contents. Pigs were selected in pairs with low and high feed conversion ratio. The microorganisms of individuals with different FE were clustered according to diversity. The genus Prevotella was the most enriched in both groups, and the abundance of species Prevotella sp. CAG:604 was significantly increased in low efficiency individuals compared to that in animals showing high efficiency. In contrast, other differential species, including lactic acid bacteria, were all enriched in the group with good feeding characteristics. Functional analysis based on the Kyoto Encyclopedia of Genes and Genomes databases demonstrated that differential genes for the metabolism of carbohydrates were most abundant in both groups, but pathways of pyruvate-related metabolism were more intense in pigs with higher FE. All these data indicated that the microbial environment was closely related to the growth traits of pigs, and regulating microbial composition could aid developing strategies to improve FE for pigs.

    The antimicrobial peptide, epinecidin-1 (Epi), was identified from Epinephelus coioides and may have clinical application for treating sepsis. Epi has been shown to ameliorate antibiotic-resistant bacteria-induced sepsis in mice, but further evaluation in mixed-flora models and a description of the protective mechanisms are essential to establish this peptide as a potential therapeutic. Therefore, we first tested the protective effects of Epi against polymicrobial sepsis-induced bactericidal infection, inflammation and lung injury that result from cecal ligation and puncture in mice. Furthermore, since lipopolysaccharide (LPS) is a key inducer of inflammation during bacterial infection and sepsis, we also tested the LPS-antagonizing activity and related mechanisms of Epi-mediated protection in mice with LPS-induced endotoxemia and LPS-treated Raw264.7 mouse macrophage cells. Epi rescued mice from both polymicrobial sepsis and endotoxemia after delayed administration and suppressed both lung and systemic inflammatory responses, while attenuating lung injury and diminishing bacterial load. In vitro studies revealed that Epi suppressed LPS-induced inflammatory cytokine production. Mechanistically, Epi disrupted the interaction between LPS and LPS binding protein, competed with LPS for binding on the cell surface, and inhibited Toll-like receptor 4 endocytosis, resulting in inhibition of LPS-induced reactive oxygen species/p38/Akt/NF-κB signaling and subsequent cytokine production. Overall, our results demonstrate that Epi is a promising therapeutic agent for endotoxemia and polymicrobial sepsis. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study examined the effects of different combinations of inulin and postbiotics RG14 on growth performance, cecal microbiota, volatile fatty acids (VFA), and ileal cytokine expression in broiler chickens. Two-hundred-and sixteen, one-day-old chicks were allocated into 6 treatment groups, namely, a basal diet (negative control, NC), basal diet + neomycin and oxytetracycline (positive control, PC), T1 = basal diet + 0.15% postbiotic RG14 + 1.0% inulin, T2 = basal diet + 0.3% postbiotic RG14 + 1.0% inulin, T3 = basal diet + 0.45% postbiotic RG14 + 1.0% inulin, and T4 = basal diet + 0.6% postbiotic RG14 + 1.0% inulin, and fed for 6 weeks. The results showed that birds fed T1 and T3 diets had higher (P  0.05) among diets. The NC birds had higher (P inulin combinations are potential replacements for antibiotic growth promoters in the poultry industry. © 2016 Poultry Science Association Inc.

    Sepsis is characterized as a systemic inflammatory response syndrome during infection, which can result in multiple organ dysfunction and death. Ursolic acid (UA), a pentacyclic triterpene acid, has been reported to have potent anti-inflammatory and antioxidant properties. The aim of this study was to detect the possible protective effects of UA on sepsis-evoked acute lung injury. A rat model of sepsis induced by cecal ligation and puncture (CLP) was used. Rats were injected intraperitoneally with UA (10 mg/kg) after CLP, and then the survival was determined twice a day for 4 d. The protective effects of UA on CLP-induced acute lung injury were assayed at 24 h after CLP. The results revealed that UA treatment markedly improved the survival of septic rats, and attenuated CLP-induced lung injury, including reduction of lung wet/dry weight ratio, infiltration of leukocytes and proteins, myeloperoxidase activity, and malondialdehyde content. In addition, UA significantly decreased the serum levels of tumor necrosis factor-α, interleukin-6, and interleukin-1β, inhibited the expression of inducible nitric oxide synthase and cyclooxygenase-2 in the lung, which are involved in the productions of nitric oxide and prostaglandin E2. These findings indicate that UA exerts protective effects on CLP-induced septic rats. UA may be a potential therapeutic agent against sepsis. Copyright © 2015 Elsevier Inc. All rights reserved.

    Mortality in the ICU frequently results from the synergistic effect of two temporally-distinct infections. This study examined the pathophysiology of a new model of intraabdominal sepsis followed by methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. Mice underwent cecal ligation and puncture (CLP) or sham laparotomy followed three days later by an intratracheal injection of MRSA or saline. Both CLP/saline and sham/MRSA mice had 100% survival while animals with CLP followed by MRSA pneumonia had 67% seven-day survival. Animals subjected to CLP/MRSA had increased bronchoalveolar lavage (BAL) concentrations of MRSA compared to sham/MRSA animals. Animals subjected to sham/MRSA pneumonia had increased BAL levels of IL-6, TNF-α, and G-CSF compared to those given intratracheal saline while CLP/MRSA mice had a blunted local inflammatory response with markedly decreased cytokine levels. Similarly, animals subjected to CLP/saline had increased peritoneal lavage levels of IL-6 and IL-1β compared to those subjected to sham laparotomy while this response was blunted in CLP/MRSA mice. Systemic cytokines were upregulated in both CLP/saline and sham/MRSA mice, and this was blunted by the combination of CLP/MRSA. In contrast, no synergistic effect on pneumonia severity, white blood cell count or lymphocyte apoptosis was identified in CLP/MRSA mice compared to animals with either insult in isolation. These results indicate that a clinically relevant model of CLP followed by MRSA pneumonia causes higher mortality than could have been predicted from studying either infection in isolation, and this was associated with a blunted local (pulmonary and peritoneal) and systemic inflammatory response and decreased ability to clear infection.

    The purpose of the present study was to better understand the events involved in the febrile response induced by cecal ligation and puncture (CLP), a complex infectious process. To this end, we conducted in vivo experiments in rats examining (1) fever development, (2) bacterial number in the infection focus and in blood, (3) peripheral and hypothalamic synthesis of cytokines, (4) hypothalamic and cerebrospinal fluid (CSF) synthesis of prostaglandin E(2) (PGE(2)), (5) the effect of anti-IL-6 antibody on fever, and (6) the effect of celecoxib on fever and hypothalamic synthesis of PGE(2) after CLP induction. We found that CLP promotes fever and animal death depending on the number of punctures. The peak of CLP-induced fever overlapped with the maximal increase in the number of bacteria in the infectious focus and blood, which occurred at 6 and 12 h. The peak of the febrile response also coincided with increased amounts of interleukin (IL)-1β, IL-6 and IL-10 in the peritoneal exudate and serum; IL-6 in the hypothalamus and PGE(2) in the CSF and predominantly in the hypothalamus. Moreover, intracerebroventricularly injected anti-IL-6 antibody reduced the febrile response while celecoxib reduced the fever and PGE(2) amount in the hypothalamus induced by CLP. Tumor necrosis factor (TNF)-α peaked at 3 h at all sites studied. Conversely, IL-10 concentration decreased in the hypothalamus. These findings show that the peak of CLP-induced fever is accompanied by an increase of bacteria in peritoneal fluid (local infection) and blood; local synthesis of pyrogenic (IL-1β, IL-6) and antipyretic (IL-10) cytokines and central production of IL-6 and PGE(2), suggesting that these last are the central mediators of this response.

    Full Text Available Photoperiod is an important factor in stimulating broiler performance in commercial poultry practice. However, the mechanism by which photoperiod affects the performance of broiler chickens has not been adequately explored. The current study evaluated the effects of three different photoperiod regimes (short day (LD = 8 h light, control (CTR = 12.5 h light, and long day (SD = 16 h light on the cecal microbiota of broiler roosters by sequencing bacterial 16S rRNA genes. At the phylum level, the dominant bacteria were Firmicutes (CTR: 68%, SD: 69%, LD: 67% and Bacteroidetes (CTR: 25%, SD: 26%, and LD: 28%. There was a greater abundance of Proteobacteria (p < 0.01 and Cyanobacteria (p < 0.05 in chickens in the LD group than in those in the CTR group. A significantly greater abundance of Actinobacteria was observed in CTR chickens than in SD and LD chickens (p < 0.01. The abundance of Deferribacteres was significantly higher in LD chickens than in SD chickens (p < 0.01. Fusobacteria and Proteobacteria were more abundant in SD chickens than in CTR and LD chickens. The predicted functional properties indicate that cellular processes may be influenced by photoperiod. Conversely, carbohydrate metabolism was enhanced in CTR chickens as compared to that in SD and LD chickens. The current results indicate that different photoperiod regimes may influence the abundance of specific bacterial populations and then contribute to differences in the functional properties of gut microbiota of broiler roosters.

    Nopal is a cactus plant widely consumed in Mexico that has been used in traditional medicine to aid in the treatment of type-2 diabetes. We previously showed that chronic consumption of dehydrated nopal ameliorated hepatic steatosis in obese (fa/fa) rats; however, description of the effects on other tissues is sparse. The aim of the present study was to investigate the effects of nopal cladode consumption on intestinal physiology, microbial community structure, adipose tissue, and serum biochemistry in diet-induced obese rats. Rats were fed either a normal fat (NF) diet or a HF diet containing 4% of dietary fiber from either nopal or cellulose for 6 weeks. Consumption of nopal counteracted HF-induced adiposity and adipocyte hypertrophy, and induced profound changes in intestinal physiology. Nopal consumption reduced biomarkers of intestinal inflammation (mRNA expression of IL-6) and oxidative stress (ROS), modfied gut microbiota composition, increasing microbial diversity and cecal fermentation (SCFA), and altered the serum metabolome. Interestingly, metabolomic analysis of dehydrated nopal revealed a high choline content, which appeared to generate high levels of serum betaine, that correlated negatively with hepatic triglyceride (TAG) levels. A parallel decrease in some of the taxa associated with the production of trimethylamine, suggest an increase in choline absorption and bioavailability with transformation to betaine. The latter may partially explain the previously observed effect of nopal on the development of hepatic steatosis. In conclusion, this study provides new evidence on the effects of nopal consumption on normal and HF-diet induced changes in the intestine, the liver and systemic metabolism.

    Full Text Available Antimicrobial therapy for sepsis has beneficial effects, but prolonged use fosters emergence of resistant microorganisms, increases cost, and secondary infections. We tested whether 3 days versus 5 days of antibiotics in the murine model of cecal ligation and puncture (CLP negatively influences outcomes. Following CLP mice were randomized to receive the antibiotic imipenem-cilastatin (25mg/kg in dextrose 5% in Lactated Ringer's solution every 12 hours for either three or five days. Serial monitoring over 28 days included body weight, temperature, pulse oximetry, and facial vein sampling for hematological analysis and glucose. A separate group of mice were euthanized on post-CLP day 5 to measure cytokines and peritoneal bacterial counts. The first study examined no antimicrobial therapy and demonstrated that antibiotics significantly improved survival compared to fluids only (p = 0.004. We next tested imipenem-cilastatin therapy for 3 days versus 5 days. Body weight, temperature, glucose, and pulse oximetry measurements remained generally consistent between both groups as did the hematological profile. Pro-inflammatory plasma cytokines were comparable between both groups for IL-6, IL-1β, MIP-2 and anti-inflammatory cytokines IL-10, and TNF SRI. At 5 days post-CLP, i.e. 2 days after the termination of antibiotics in the 3 day group, there were no differences in the number of peritoneal bacteria. Importantly, shortening the course of antibiotics by 40% (from 5 days to 3 days did not decrease survival. Our results indicate that reducing the duration of broad-spectrum antibiotics in murine sepsis did not increase inflammation or mortality.

    The effects of hypertonic saline solution (HSS) have been shown in several animal models of ischemia and shock. Literature has shown potential benefits of HSS modulating inflammatory response after sepsis in an animal model. We studied the HSS effects in sepsis through cecal ligation and puncture (CLP) in Balb-C mice. Groups studied: 1- CLP without treatment (CLP-C); 2- CLP treated with normal saline solution NaCl 0.9% – 34 ml/Kg (CLP-S); 3- CLP treated with HSS NaCl 7.5% – 4 ml/Kg (CLP-H); and 4- group (Basal) without no CLP or treatment. Volume infusion was always applied 30 min after CLP. Lung and peritoneal lavage were harvested after 6h and 24h of CLP to analyze cytokines amount, oxide nitric, lipid peroxidation and neutrophil infiltration. Neutrophil infiltration, ICAM-1, CXCR-2, and CXCL-1 in lung were reduced by HSS (CLP-H) compared to CLP-C or CLP-S. Neutrophil in peritoneal lavage was increased in 24h with HSS (CLP-H) compared to CLP and CLP-S. Peritoneal CXCR-2 was increased in CLP-C and CLP-S but presented a lower increase with HSS (CLP-H) after 6 hours. GRK-2 presented difference among the groups at 24 h, showing a profile similar to neutrophil infiltration. Pro-inflammatory cytokines (TNF-α and IL-6) were reduced by HSS treatment; CLP-S increased TNF-α. IL-10 was increased in lung tissue by the HSS treatment. The oxidative stress (TBARS and nitric oxide biochemistry markers) was reduced with HSS. Animal survival was 33.3% in CLP-C group, 46.6% in CLP-S group and 60% in the CLP-H group after the sixth day. The HSS protects the animal against sepsis. Our results suggest that the volume replacement modulate pro and anti-inflammatory mediators of an inflammatory response, but HSS presented a more effective and potent effect. PMID:24069301

    Diarrhea incidence in weaned pigs may be associated with the concentration of intestinal microbial metabolites (ammonia, amines, and VFA) that are influenced by dietary CP content. Three experiments were conducted to determine effects of a low-protein, AA-supplemented diet on ileal AA digestibility, growth performance, diarrhea incidence, and concentration of microbial metabolites in ileal and cecal digesta of pigs weaned at 14 d of age. In Exp. 1, 8 pigs fitted with a simple T-cannula at the distal ileum were assigned in a crossover design to 2 diets containing 24 or 20% CP using wheat, corn, full-fat soybeans, whey powder, fish meal, and blood plasma as the main ingredients. Supplemental AA were added to the diets to meet the AA standards according to the 1998 NRC recommendations. Chromic oxide was used as an indigestible marker. Diets were fed at 2.5 times the ME requirement for maintenance. The reduction of dietary CP decreased (P water. Dietary CP content did not affect growth performance or fecal consistency scores during the 3-wk study, and diarrhea was not observed. The results of these experiments indicate that lowering the dietary CP content combined with supplementation of AA markedly reduced the production of potentially harmful microbial metabolites in cecal digesta of early-weaned pigs without affecting growth performance.

    Both chromium (Cr) and probiotic bacillus own the virtues of regulating animal metabolism and meat quality. Purpose of this study was to evaluate the efficiency of supplemental Cr and bacillus in the form of chromium-enriched Bacillus subtilis KT260179 (CEBS) on chicken growth performance, plasma lipid parameters, tissue chromium levels, cecal bacterial composition and breast meat quality. Six hundred of 1-day-old Chinese Huainan Partridge chickens were divided into four groups randomly: Control, inorganic Cr, Bacillus subtilis, and CEBS. The feed duration was 56 days. After 28 days of treatment, broiler feed CEBS or normal B. subtilis had higher body weights than control broiler, and after 56 days, chickens given either CEBS or B. subtilis had greater body weights than control broiler or those given inorganic Cr. Plasma total cholesterol, triglycerides, and low density lipoprotein cholesterol levels declined significantly in the CEBS group compared with the control, whereas plasma high density lipoprotein cholesterol levels increased significantly. The concentration of Cr in blood and breast muscle increased after CEBS and inorganic Cr supplementation. B. subtilis and CEBS supplementation caused a significant increase in the numbers of Lactobacillus and Bifidobacterium in the caecum, while the numbers of Escherichia coli and Salmonella decreased significantly compared to the control. Feed adding CEBS increased the lightness, redness, and yellowness of breast meat, improved the water-holding capacity, decreased the shear force and cooking loss. In all, CEBS supplementation promoted body growth, improved plasma lipid parameters, increased tissue Cr concentrations, altered cecal bacterial composition and improved breast meat quality.

    With the increasing production of ethanol for biofuels, a by-product of corn-based ethanol fermentation, dried distillers grains with solubles (DDGS) is finding its way into the feed of agricultural animals including cattle, pigs, poultry, sheep, goats, aquaculture species and horses. Corn DDGS contains very high levels of non-starch polysaccharides and could be considered a good source of fibre. Despite knowledge of the role of the fibre in modulating intestinal microbiota and consequently influencing health, there is currently little information on the interactions between DDGS and intestinal microbiota. We assessed the changes in the cecal microbiota of broilers feed rations supplemented with DDGS (five concentrations: 0, 6, 12, 18 and 24% w/w) with and without presence of digestive enzymes. DDGS concentration was strongly positively correlated (P = 3.7e -17 , r = 0.74) with feed conversion efficiency (FCR), diminishing broiler performance with higher concentrations. Additionally, DDGS concentrations positively correlated with Richness index (P = 1.5e -3 , r = 0.5), increasing the number of detectable species in the cecum. Among the most affected genera, Faecalibacterium (P = 0.032, r = -0.34) and Streptococcus (P = 7.9e -3 , r = -0.39) were negatively correlated with DDGS, while Turicibacter (P = 2.8e -4 , r = 0.52) was positively correlated with the DDGS concentration. Enzymes showed minimal effect on cecal microbiota.

    Limiting the post-weaning intake of the young rabbit is known to improve its resistance to digestive disorders, whereas a degradation of its housing hygiene is assumed to have a negative impact on its health. This study aims at providing insights into the mechanism of digestive health preservation regarding both host (growth and immune response) and its symbiotic digestive microbiota. A 2×2 factorial design from weaning (day 28) to day 64 was set up: ad libitum intake or restricted intake at 70% of ad libitum, and high v. low hygiene of housing (n=105 per group). At day 36 and day 45, 15 animals/group were subcutaneously immunized with ovalbumin (OVA) to assess their specific immune response. Blood was sampled at 36, 45, 57 and 64 days of age to determine total and anti-OVA immunoglobulin type G (IgG) and haptoglobin levels. The cecal bacterial community was explored (18 per group) by 454 pyrosequencing of genes coding for the 16S ribosomal RNA, whereas cecal pH, NH3 and volatile fatty acid (VFA) concentrations were measured to characterize fermentative activity. A 30% reduction in feed intake reduced the growth by only 17% (Pratio by 15% (Pratio (3.7 v. 2.4; Phighest in animals raised in poor hygiene conditions after 8 days of restriction, but decreased after 19 days of restriction in high hygiene conditions (-2.15%; Presponse in rabbit, but reduced morbidity instead. Our results suggest that the microbiota composition would be a helpful source of biomarkers of digestive health.

    Dietary interventions are a common practice in the poultry industry to promote optimal performance and health of animals. Here, we aim at assessing the influence of supplementing broiler diets with dry whey powder (DWP) and whey protein concentrate (WPC) on nutrient coefficient of apparent ileal digestibility (CAID) and productive performance. Cecal microbiota composition was also determined using Illumina amplicon sequencing. Dietary treatments were control diet (no supplementation of DWP or WPC), 60-DWP (60 g/kg of DWP), and 80-WPC (80 g/kg of WPC). One-day-old male broilers were randomly assigned to one of three treatments, and housed in floor pens. In Trial 1, 90 1-day-old chicks were allocated to three pens/treatment, with 10 birds/pen, during 21 days for CAID evaluation. Diet 60-DWP increased Ca CAID (P=0.041), while diet 80-WPC improved Ca and P CAID (PWPC increased their BW, average daily gain (ADG) and feed intake (FI) during the starter (PWPC reduced the feed conversion ratio of chickens during the starter period (PWPC differed from those fed with control diet (R=0.776, P=0.008; and R=0.740, P=0.008, respectively). The abundance of Bacteroides fragilis, Bacteroides spp., Escherichia coli/Shigella flexneri and Megamonas furniformis increased when 60-DWP and 80-WPC diets were offered, while the presence of Helicobacter pullorum decreased. Lactobacillus salivarius consistently increased in chickens with better feed conversion ratio, which were those fed with 60-DWP. The results obtained in the present study indicate that growth of chickens is improved by DWP and WPC supplementation because of a higher mineral digestibility, increased feed intake and modulation of cecal microbiota communities.

    Research on the interaction between dietary vitamins and intestinal bacteria is poorly understood. To investigate the effect of dietary vitamins on the cecal bacterial communities, 2 bacterial 16S rRNA gene clone libraries were constructed from pooled PCR products obtained from the cecal digesta of 28-d broilers fed diets with vitamins (V) at the NRC level or with no vitamins (NV). The results showed that BW gain and average feed intake of V broilers was significantly higher (P vitamins can increase the ratio of facultative pathogenic bacteria and decrease the diversity of bacteria in the cecum of broilers. Our results provide new leads for further investigations on the interaction between dietary vitamin additives and the gut health of broilers.

    Full Text Available Feed supplements are utilized in the poultry industry as a means for improving growth performance and reducing pathogens. The aim of the present study was to evaluate the effects of Diamond V Original XPCTM (XPC, a fermented product generated from yeast cultures on Salmonella Typhimurium ST 97 along with its potential for modulation of the cecal microbiota by using an anaerobic in vitro mixed culture assay. Cecal slurries obtained from three broiler chickens at each of three sampling ages (14, 28, and 42 days were generated and exposed to a 24 h pre-incubation period with the various treatments: XPC (1% XPC, ceca, and feeds, CO (ceca only, and NC (negative control group consisting of ceca and feeds. The XPC, CO, and NC were each challenged with S. Typhimurium and subsequently plated on selective media at 0, 24, and 48 h. Plating results indicated that the XPC treatment significantly reduced the survival of S. Typhimurium at the 24 h plating time point for both the 28 and 42 days bird sampling ages, while S. Typhimurium reduction in the NC appeared to eventually reach the same population survival level at the 48 h plating time point. For microbiome analysis, Trial 1 revealed that XPC, CO, and NC groups exhibited a similar pattern of taxa summary. However, more Bacteroidetes were observed in the CO group at 24 and 48 h. There were no significant differences (P > 0.05 in alpha diversity among samples based on day, hour and treatment. For beta diversity analysis, a pattern shift was observed when samples clustered according to sampling hour. In Trial 2, both XPC and NC groups exhibited the highest Firmicutes level at 0 h but the Bacteroidetes group became dominant at 6 h. Complexity of alpha diversity was increased in the initial contents from older birds and became less complex after 6 h of incubation. Beta diversity analysis was clustered as a function of treatment NC and XPC groups and by individual hours including 6, 12, 24, and 48 h. Overall

Methods A total of 300, 1-d-old healthy broiler chickens were randomly divided into five treatment groups: i basal diet (control, ii basal diet+0.25% yeast (Saccharomyces cerevisiae (YC, iii basal diet+0.25% yeast with bacteriocin (BA, iv basal diet+Lactobacillus cultures (LAB, and v basal diet +0.25% yeast with bacteriocin+Lactobacillus cultures (BA+LAB. Growth performance, cecal microbiota, cecal fermentation products, and blood biochemistry parameters were determined when chickens were 21 and 35 d old. Results The supplementation of YC, BA, and BA+LAB resulted in a significantly better feed conversion rate (FCR than that of the control group during 1 to 21 d (p<0.05. The LAB supplementation had a significant effect on the presence of Lactobacillus in the ceca at 35 d. None of the supplements had an effect on relative numbers of L. agilis and L. reuter at 21 d, but the BA supplementation resulted in the decrease of both Lactobacillus strains at 35 d. The BA+LAB supplementation resulted in higher short chain fatty acid (SCFA in the ceca, but LAB supplementation significantly decreased the SCFA at 35 d (p<0.05. All treatments tended to decrease ammonia concentration in the ceca at 21 d, especially in the LAB treatment group. The BA supplementation alone decreased the triacylglycerol (TG concentration significantly at 21 d (p<0.05, but the synergistic effect of BA and LAB supplementation was required to reduce the TG concentration at 35 d. The YC supplementation tended to increase the plasma cholesterol at 21 d and 35 d. However, the BA supplementation significantly decreased the cholesterol and low density lipoprotein cholesterol level at 35 d. In conclusion, the BA

    Dobutamine has been used in septic shock for many years as an only inotrope, but its benefit has been questioned. We weighed the effects of dobutamine and milrinone as inotropes in mice with cecal ligation and puncture (CLP)-induced polymicrobial sepsis. CLP-induced septic mice exhibited significant cardiac inflammation, as indicated by greatly increased mRNAs of proinflammatory cytokines and robust infiltration of inflammatory cells in the ventricular myocardium. Elevations of plasma cardiac troponin-I showed cardiac injury in CLP mice. Noninvasive echocardiographic assessment of cardiac function revealed that despite preserved left ventricular function in the presence of fluid replacement, the dobutamine inotropic response was significantly impaired in CLP mice compared with sham-operated controls. By contrast, milrinone exerted inotropic effects in sham-operated and CLP mice in an equally effective manner. Surface expression levels of β 1 -adrenoceptors and α-subunits of three main G protein families in the myocardium were unaffected by CLP-induced sepsis. Plasma cAMP levels were significantly elevated in both sham-operated and CLP mice in response to milrinone but only in sham-operated controls in response to dobutamine. Of phosphodiesterase (PDE) isoforms, PDE4D, but not PDE3A, both of which are responsible for cardiac cAMP hydrolysis, was significantly upregulated in CLP mouse myocardium. We define a novel mechanism for the impaired responsiveness to dobutamine as an inotrope in sepsis, and understanding the role of PDE4D in modulating cardiac functional responsiveness in sepsis may open the potential of a PDE4D-targeted therapeutic option in septic patients with low cardiac output who have a need for inotropic support. NEW & NOTEWORTHY Advisability of the usefulness of dobutamine in septic shock management is limited. Here, we reveal that the effect of dobutamine as a positive inotrope is impaired in mice with cecal ligation and puncture-induced sepsis

    Full Text Available Fluoride is an environmental and industrial pollutant that affects various organs in humans and animals. The cecal tonsil is an important component of the mucosal immune system and performs important and unique immune functions. In the present study, we investigated the effects of dietary high fluorine on the quantities of IgA+ B cells in the cecal tonsil by immunohistochemistry, and the immunoglobulin A (IgA, immunoglobulin G (IgG and immunoglobulin M (IgM contents in the cecal tonsil by ELISA. A total of 280 one-day-old avian broilers were divided into four groups and fed on a corn-soybean basal diet as control diet (fluorine 22.6 mg/kg or the same diet supplemented with 400, 800 and 1,200 mg/kg fluorine (high fluorine groups I, II and III in the form of sodium fluoride, respectively, throughout a 42-day experimental period. The results showed that the quantities of IgA+ B cells were lower (p < 0.05 or p < 0.01 and the IgA, IgG, and IgM contents were decreased (p < 0.05 or p < 0.01 in high fluorine groups II and III in comparison with those of control group. It was concluded that dietary fluorine, in the 800–1,200 mg/kg range, could reduce the numbers of the IgA+ B cells and immunoglobulin contents in the cecal tonsil, implying the local mucosal immune function was ultimately impacted in broilers.

    Full Text Available Foram avaliados 10 eqüinos da raça Manga Larga, machos, inteiros clinicamente sadios, submetidos à punção cecal percutânea. Analisou-se a resposta clínica, celular, bioquímica e microbiológica do líquido peritoneal por um período de 24 horas após a punção cecal, nos tempos T0, T6, T12 e T24. Foi observada elevação na freqüência respiratória em T6 e na temperatura retal entre T6 e T12. Decorridas 24 horas da punção cecal, ocorreu aumento na concentração de proteínas totais do líquido peritoneal e na atividade da fosfatase alcalina. Tanto a atividade da ALT quanto os níveis de hemoglobina apresentaram diminuição em T6. Não foram registradas alterações na celularidade do plasma ou do líquido peritoneal e obteve-se resultado negativo para a cultura microbiológica do líquido. Considerando a inexistência de efeitos adversos, além das poucas alterações descritas, conclui-se que a punção cecal percutânea é um procedimento seguro e factível, se praticada criteriosamente.

    Acute liver injury secondary to sepsis is a major challenge in intensive care unit. This study was designed to investigate potential protective effects of pomegranate against sepsis-induced acute liver injury in rats and possible underlying mechanisms. Pomegranate was orally given (800mg/kg/day) for two weeks before sepsis induction by cecal ligation and puncture (CLP). Pomegranate improved survival and attenuated liver inflammatory response, likely related to downregulation of mRNA expression of toll like recptor-4, reduced nuclear translocation and DNA binding activity of proinflammatory transcription factor NF-κB subunit p65, decreased mRNA and protein expression of tumor necrosis factor-alpha and reduction in myeloperoxidase activity and mRNA expression. Pomegranate also decreased CLP-induced oxidative stress as reflected by decreased malondialdehyde content, and increased reduced glutathione level and superoxide dismutase activity. These results confirm the antiinflammatory and antioxidant effects of pomegranate in CLP-induced acute liver injury mediated through inhibiting TLR4/NF-κB pathway, lipid peroxidation and neutrophil infiltration.

    Full Text Available Innate immunity is the first line of defense in human beings against pathogen infection; monocytes/macrophages are the primary cells of the innate immune system. Recently, macrophages/monocytes have been discovered to participate in LPS clearance, and the clearance efficiency determines the magnitude of the inflammatory response and subsequent organ injury. Previously, we reported that artesunate (AS protected sepsis mice against heat-killed E. coli challenge. Herein, we further confirmed that AS protected cecal ligation/puncture (CLP sepsis mice. Its protection on sepsis mice was related to not only reduction of pro-inflammatory cytokines and serum LPS levels but also improvement of liver function. Based on the fact that AS did not directly bind and neutralize LPS, we hypothesized that the reduction of serum LPS level might be related to enhancement of LPS internalization and subsequent detoxification. Our results showed that AS increased FITC-LPS internalization by peritoneal macrophage and liver Kupffer cell, but enhancement of LPS internalization by AS was not related to the clathrin-dependent pathway. However, AS induced mRNA expression of important scavenger receptors (SRs; SR-A and MARCO mRNA expression was upregulated, suggesting that AS enhancement of LPS internalization and inhibition of pro-inflammatory cytokines was related to changes in mRNA expression of SRs.

    We tested whether apoptotic adipose-derived mesenchymal stem cells (A-ADMSCs) were superior to healthy (H)-ADMSCs at attenuating organ damage and mortality in sepsis syndrome following cecal ligation and puncture (CLP). Adult male rats were categorized into group 1 (sham control), group 2 (CLP), group 3 [CLP + H-ADMSC administered 0.5, 6, and 18 h after CLP], group 4 [CLP + A-ADMSC administered as per group 3]. Circulating peak TNF-α level, at 6 h, was highest in groups 2 and 3, and higher in group 4 than group 1 (p HO-1, NQO-1) showed an opposite way of Bcl-2; these patterns were reversed for group 4 (all p < 0.001). Mortality was highest in group 3 and higher in group 2 than group 4 than group 1 (all p < 0.001). A-ADMSC therapy protected major organs from damage and improved prognosis in rats with sepsis syndrome.

    The objective of the present study was to investigate the ability of animal feed-grade sodium bisulfate (SBS) and a mixture of sodium bisulfate/tannin to inhibit the growth of Salmonella using an anerobic in vitro mixed cecal culture to mimic the conditions within the chicken cecum. An initial inoculum of Salmonella Typhimurium was introduced to an anerobic dilution solution containing 1/3000 diluted cecal bacteria and solids consisting of ground chicken feed and different percentages of solid SBS or SBS/tannin, and surviving organisms were enumerated. Two different experimental designs were employed. In the "unadapted" treatment, the S. Typhimurium was added at the beginning of the culture incubation along with cecal bacteria and chicken feed/SBS or chicken feed/SBS/tannin. In the "adapted" treatment, S. Typhimurium was added after a 24 hour pre-incubation of the cecal bacteria with the chicken feed/SBS or chicken feed/SBS/tannin. Adding SBS resulted in reduction of pH in the cultures which paralleled with the reduction of S. Typhimurium. The SBS alone was found to be inhibitory to S. Typhimurium in the adapted treatment at all concentrations tested (0.25, 0.5, and 0.75%), and the degree of inhibition was concentration-dependent. Salmonella Typhimurium was completely killed in the adapted culture with 0.5% SBS after 24 and 48 h. The SBS/tannin mixture was less inhibitory than SBS alone at the same concentrations in side-by-side comparisons. Testing at a 0.5% SBS concentration, chicken age had little or no effect on log reduction of S. Typhimurium relative to age-matched control cultures without SBS, but age did affect the absolute number of S. Typhimurium surviving, with the greatest decreases occurring at 2 and 4 weeks of age (approx. 10 3 S. Typhimurium surviving) compared to 6 weeks of age (approx. 10 5 Salmonella surviving). Microbiome analysis with an Illumina MiSeq platform was conducted to investigate bacterial compositional changes related to the

    Mortality in the intensive care unit frequently results from the synergistic effect of two temporally distinct infections. This study examined the pathophysiology of a new model of intra-abdominal sepsis followed by methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. Mice underwent cecal ligation and puncture (CLP) or sham laparotomy followed 3 days later by an intratracheal injection of MRSA or saline. Both CLP/saline and sham/MRSA mice had 100% survival, whereas animals with CLP followed by MRSA pneumonia had 67% 7-day survival. Animals subjected to CLP/MRSA had increased bronchoalveolar lavage concentrations of MRSA compared with sham/MRSA animals. Animals subjected to sham/MRSA pneumonia had increased bronchoalveolar lavage levels of interleukin 6 (IL-6), tumor necrosis factor α, and granulocyte colony-stimulating factor compared with those given intratracheal saline, whereas CLP/MRSA mice had a blunted local inflammatory response with markedly decreased cytokine levels. Similarly, animals subjected to CLP/saline had increased peritoneal lavage levels of IL-6 and IL-1β compared with those subjected to sham laparotomy, whereas this response was blunted in CLP/MRSA mice. Systemic cytokines were upregulated in both CLP/saline and sham/MRSA mice, and this was blunted by the combination of CLP/MRSA. In contrast, no synergistic effect on pneumonia severity, white blood cell count, or lymphocyte apoptosis was identified in CLP/MRSA mice compared with animals with either insult in isolation. These results indicate that a clinically relevant model of CLP followed by MRSA pneumonia causes higher mortality than could have been predicted from studying either infection in isolation, and this was associated with a blunted local (pulmonary and peritoneal) and systemic inflammatory response and decreased ability to clear infection.

    Full Text Available Sepsis is a systemic inflammatory response syndrome caused by an infection and remains as a major challenge in health care. Many studies have reported that pioglitazone may display anti-inflammatory effects. This study was designed to evaluate the effect of subchronic treatment with pioglitazone on high-grade septic mice survival and nitrergic system involvement. Diffused sepsis was induced by cecal ligation and puncture (CLP surgery in male NMRI mice (20-30 g. Pioglitazone (5,10 and 20 mg/kg was administered by gavage daily for 5 days prior to surgery. Nitric oxide involvement was assessed by sub-chronic administration of a non-selective nitric oxide synthase inhibitor, L-NAME and a selective inducible nitric oxide synthase inhibitor, aminoguanidine. TNF-α  and IL-1β plasma levels were measured by ELISA. Pioglitazone (10 and 20 mg/kg significantly improved survival rate in septic mice. The chronic intraperitoneally co-administration of L-NAME (0.5 mg/kg, daily or aminoguanidine (1 mg/kg, daily with a daily dose of pioglitazone, 5 mg/kg, significantly increased the survival rate. This survival improving effect was accompanied by a significant reduction in pro-inflammatory cytokines TNF-α and IL-1β plasma levels. In conclusion, sub-chronic pioglitazone treatment can improve survival in mouse sepsis model by CLP. Inhibition of nitric oxide release, probably through inducible nitric oxide synthase at least in part is responsible for this effect. Suppression of TNF-α and IL-1β could be another mechanism in pioglitazone-induced survival improving effect in septic mice.

    BACKGROUND Blocking of TREM-1 signaling improves survival of mice with sepsis induced by Pseudomonas aeruginosa. However, whether TREM-1 blockade has beneficial effects in polymicrobial sepsis is poorly understood. Here, we aimed to investigate the effect of modulation of the TREM-1 pathway in rats with polymicrobial sepsis induced by cecal ligation and puncture (CLP). MATERIAL AND METHODS Normal Sprague-Dawley (SD) rats with sepsis induced by CLP were allocated randomly to received scramble peptide or LP17 via the jugular vein. Serum level of sTREM-1, IL6, TNF-α, and IL-1β were detected by ELISA assay. The mRNA and protein levels of JAK2 and STAT3 were detected by real-time PCR and Western blot analysis. RESULTS STREM-1 concentration was greatly and progressively increased in rats with CLP-induced sepsis, and the increase was attenuated by TREM-1 inhibitory peptide LP17. More than 60% survival was observed in rats at the experiment endpoint after LP17 treatment. TREM-1 blockade also attenuated the increased level of pro-inflammatory cytokines TNF-α, IL-6, and IL-1β, and thus attenuated systematic and distant inflammatory responses. Furthermore, TREM-1 blockade significantly attenuated the increased levels of pJAK2 and pSTAT3. CONCLUSIONS TREM-1 blockade by the use of an inhibitory peptide LP17 could prolong survival of rats with polymicrobial sepsis and attenuate systematic inflammatory responses through the JAK2/STAT3 signaling pathway. Our results suggest that modulation of TREM-1 by a synthetic peptide might be a potential therapeutic option for polymicrobial sepsis.

    Full Text Available Abstract Background Septic shock remains a leading cause of death worldwide. Hyperbaric oxygen treatment (HBO2 has been shown to alter the inflammatory response during sepsis and to reduce mortality. A therapeutic window of HBO2 treatment has been demonstrated experimentally, but optimal timing remains uncertain. We investigated the effects of 24 h delayed normobaric oxygen (NBO2 and HBO2 treatment on the endogenous production of the inflammatory markers interleukin (IL-6, tumor necrosis factor (TNF-α and IL-10, and on mortality in rats with cecal ligation and puncture (CLP induced sepsis. Method Fifty-five male Sprague-Dawley rats underwent CLP and were randomized to the following groups: 1 HBO2 2.5 bar absolute pressure (pabs; 2 NBO2 1.0 bar pabs; 3 Control (no-treatment, and they were individually monitored for 72 h with intermittent blood sampling. Results IL-6, TNF-α, and IL-10 were increased 24 h after the procedure, and IL-6 was significantly higher in non-survivors than in survivors. The level of IL-10 was significantly higher at hour 48 in the HBO2 group compared to control (p = 0.01, but this was not the case at other time points. No other significant differences in cytokine levels were found for any group comparisons. Delayed NBO2 and HBO2 treatment failed to change the mortality in the animals. Conclusion High levels of IL-6 in non-surviving animals with sepsis suggest that IL-6 is a potential biomarker. We found a significantly higher concentration of IL-10 in the HBO2 group at hour 48 vs. control animals. However, 24 h–delayed treatment with HBO2 did not change the levels of pro-inflammatory cytokines and survival, suggesting that earlier intervention may be required to obtain an anti-inflammatory effect.

    Text mining is a flexible technology that can be applied to numerous different tasks in biology and medicine. We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

  16. Gene deletion of P-Selectin and ICAM-1 does not inhibit neutrophil infiltration into peritoneal cavity following cecal ligation-puncture

    Full Text Available Abstract Background Neutrophil infiltration is one of the critical cellular components of an inflammatory response during peritonitis. The adhesion molecules, P-selectin and intercellular adhesion molecule (ICAM-1, mediate neutrophil-endothelial cell interactions and the subsequent neutrophil transendothelial migration during the inflammatory response. Despite very strong preclinical data, recent clinical trials failed to show a protective effect of anti-adhesion therapy, suggesting that the length of injury might be a critical factor in neutrophil infiltration. Therefore, the objective of this study was to determine the role of P-selectin and ICAM-1 in neutrophil infiltration into the peritoneal cavity during early and late phases of peritonitis. Methods Peritonitis was induced in both male wild-type and P-selectin/ICAM-1 double deficient (P/I null mice by cecal ligation-puncture (CLP. Peripheral blood and peritoneal lavage were collected at 6 and 24 hours after CLP. The total leukocyte and neutrophil contents were determined, and neutrophils were identified with the aid of in situ immunohistochemical staining. Comparisons between groups were made by applying ANOVA and student t-test analysis. Results CLP induced a severe inflammatory response associated with a significant leukopenia in both wild-type and P/I null mice. Additionally, CLP caused a significant neutrophil infiltration into the peritoneal cavity that was detected in both groups of mice. However, neutrophil infiltration in the P/I null mice at 6 hours of CLP was significantly lower than the corresponding wild-type mice, which reached a similar magnitude at 24 hours of CLP. In contrast, in peritonitis induced by intraperitoneal inoculation of 2% glycogen, no significant difference in neutrophil infiltration was observed between the P/I null and wild-type mice at 6 hours of peritonitis. Conclusions The data suggest that alternative adhesion pathway(s independent of P-selectin and ICAM

    Disease expression in spontaneous nonobese diabetic (NOD) mice depends on environmental stimuli such as stress, diet, and gut microbiota composition. We evaluated a brief, early-life gut intervention in which pups were weaned to low-dose dextran sulfate sodium (DSS). We hypothesized that the mucus...... of the microbiota during weeks 4 through 6 led to increased cecal length and weight and, in week 13, a tendency toward decreased colon length, with increased leakage of LPS to the blood. We conclude that mucus reduction and subsequent increased host–bacterial contact did not affect overall disease progression...

    Full Text Available Lymphocytic colitis, a cause of chronic watery diarrhea, is histologically characterized by increased intraepithelial lymphocytosis. Studies have associated this disorder with celiac disease, although there are no reports of patients with both lymphocytic colitis and colon cancer. The present case report describes a patient with lymphocytic colitis, which manifested five years after he presented with a cecal adenocarcinoma, and three years following a diagnosis of celiac disease. Pathological review of his initial resection specimen demonstrated lymphocytic enterocolitis, indicating a five-year latency in the presentation of this disease.

    The fused quinazolinone derivative, RX-207, is chemically and functionally related to small molecule inhibitors of protein binding to glycosaminoglycans (SMIGs). Composed of a planar aromatic amine scaffold, it inhibits protein binding to glycosaminoglycans (GAGs). RX-207 reduced neutrophil migration in thioglycollate-induced peritonitis (37%), inhibited carrageenan-induced paw edema (32%) and cerulein-induced pancreatitis (28%), and increased animal survival in the mouse model of cecal ligation and puncture (CLP)-induced sepsis (60%). The mechanism of RX-207 action, analyzed by UV spectroscopy, confirmed that which was elucidated for chemically related anti-inflammatory SMIGs. RX-207 binding to cell surface GAGs can account for the inhibition of neutrophil recruitment via the micro-vasculature and as a consequence, the reduction of neutrophil mediated tissue damage in the animal models of inflammation and improved survival of mice in CLP-induced sepsis.

    Whole-colon water exchange (WWE) reduces insertion pain, increases cecal intubation success and adenoma detection rate, but requires longer insertion time, compared to air insufflation (AI) colonoscopy. We hypothesized that water exchange limited to the left colon (LWE) can speed up insertion with equivalent results. This prospective, randomized controlled study (NCT01735266) allocated patients (18-80 years) to WWE, LWE or AI group (1:1:1). The primary outcome was cecal intubation time. Three hundred subjects were randomized to the WWE (n = 100), LWE (n = 100) or AI group (n = 100). Ninety-four to ninety-five per cent of patients underwent diagnostic colonoscopy. Baseline characteristics were balanced. The median insertion time was shorter in LWE group (4.8 min (95%CI: 3.2-6.2)) than those in WWE (7.5 min (95%CI: 6.0-10.3)) and AI (6.4 min (95%CI: 4.2-9.8)) (both p rates in unsedated patients of the two water exchange methods (WWE 99%, LWE 99%) were significantly higher than that (89.8%) in AI group (p = 0.01). The final success rates were comparable among the three groups after sedation was given. Maximum pain scores and number of patients needing abdominal compression between WWE and LWE groups were comparable, both lower than those in AI group (p higher in WWE group. By preserving the benefits of WWE and reducing insertion time, LWE is appropriate for diagnostic colonoscopy, especially in settings with tight scheduling of patients. The higher PDR in the right colon in WWE group deserves to be further investigated.

    Full Text Available The present study was carried out to evaluate the in situ degradation of dry matter (DM, neutral detergent fiber (NDF and crude protein (CP in roughages by the in situ caecal digestion technique in horses. The roughages evaluated were: Lucerne hay (Medicago sativa, peanut (Arachis pintoi cv. Amarillo, desmodio(Desmodium ovalifolium, stylo (Stylosanthes guianensis cv. Mineirão, pigeon pea (Cajanus cajan, lime-yellow pea (Macrotyloma axillare and coastcross hay (Cynodon dactylon cv. coastcross. The assay was conducted in a complete randomized design with seven roughages and three replications. One mare with a cannula fitted in the caecum was used, fed diet consisting of coastcross hay (80% and concentrate (20% at 2.0% BW, four times a day. Nylon 6.5 × 20 cm bags were used with 45 μ/pore, containing 5.2 g DM/bag, inserting 3 or 4 bags in the caecum at the times of 2, 4, 6, 8, 12, 24 and 48 hours incubation. The caecum in situ degradability parameters of nutrients were obtained by Ørskov model. The DM degradability parameters of all the roughages were significant. There was no fit to the model for pigeon pea for CP and NDF and desmodio. Peanut, stylo and lime-yellow pea presented larger potentially degradable DM with values of 53, 46.5 and 40%, respectively, and higher values for the soluble fraction of 20, 21, 28.6%, with high degradability rates of 10.36, 20.26 and 14.8% h-1. Higher NDF degradation rates were observed in these foodstuffs with values of 9.1 and 11.3, 11.2% h-1, high potentially degradable fraction with values of 55, 51.8 and 47.2%, and greater CP degradation at 48 hours with values of 87, 95, and 94.8%. Peanut, stylo and lime-yellow pea presented potential for use in horses diets.Objetivou-se avaliar a degradação da matéria seca (MS, fibra em detergente neutro (FDN e proteína bruta de alimentos volumosos pela técnica da digestão cecal in situ em equinos.

    Full Text Available Salmonella enterica serovar Heidelberg (S. Heidelberg is a major foodborne pathogen colonizing poultry. The pathogen is associated with a significant number of foodborne outbreaks through contaminated poultry meat, including turkeys. Recently, multidrug-resistant (MDR strains of S. Heidelberg have emerged as a threat to human public health in the United States. The objective of this study was to determine the cecal colonization, dissemination to internal organs, and the potential for skeletal muscle deposition of an MDR S. Heidelberg isolate from the 2011 ground turkey outbreak in the United States after the experimental oral challenge of poults (young turkeys and adult turkey hens. In the poult study, two separate experiments using day-old, straight-run, commercial hybrid converter poults were randomly assigned to five challenge groups (0, 10∧2, 10∧4, 10∧6, 10∧8 CFU groups; 12 poults/group; N = 60/experiment and a week after, treatment groups were challenged separately with 0-, 2-, 4-, 6-, and 8- log10 CFU of S. Heidelberg orally. After 14 days post-challenge, the poults were euthanized, and samples were collected to determine MDR S. Heidelberg colonization in the cecum, dissemination to liver and spleen, and deposition in the thigh, drumstick, and breast muscles. A similar experimental design was followed for the adult turkey hens. In two separate experiments, 11-week-old commercial Hybrid Converter turkey hens (4 hens/group; N = 20/experiment were challenged with MDR S. Heidelberg and on day 16 post-challenge, birds were euthanized and samples were collected to determine Salmonella populations in the samples. The results indicated that, in turkey poults, the recovery of MDR S. Heidelberg was highest in the cecum followed by spleen, liver, thigh, drumstick, and breast. All tested inoculum levels resulted in more than 3.5 log10 CFU/g colonization in the poult cecum. The cecal colonization, dissemination to internal organs, and tissue

    Full Text Available We investigated the potential protective effects of montelukast (MLK on cecal ligation and puncture (CLP–induced tissue injury in vital organs — liver, heart, kidneys, and especially lungs — through inhibition of the proinflammatory cytokine response and the generation of reactive oxygen species (ROS in rats. The rat groups were (1 a 10-mg/kg MLK-treated CLP group; (2 a 20-mg/kg MLK-treated CLP group; (3 a 20-mg/kg MLK-treated, sham-operated group; (4 a CLP control group; and (5 a sham-operated control group. MLK treatment significantly decreased proinflammatory (tumor necrosis factor-alpha, interleukin-6 cytokine levels following CLP. The lipid peroxide level increased in the lung, heart, liver, and kidney tissues after CLP-induced sepsis, and myeloperoxidase activity increased in the lung, heart, and liver tissues. MLK attenuated this elevation in all tissues except the kidney, dose dependently. The glutathione levels and superoxide dismutase activity were significantly increased in the lung, liver, and kidney tissues after MLK treatment. MLK treatment after CLP also potentially reduced mortality. The lung and kidney tissues were the most protected by MLK under sepsis conditions. We can suggest that MLK reverses the systemic inflammatory reaction to polymicrobial sepsis and thereby reduces multiple organ failure.

    We wanted to determine the usefulness of the computed tomography (CT) findings for making the diagnosis between periappendiceal inflammation (PAI) with appendicitis and pelvic inflammatory disease (PID) for the women presenting with right lower quadrant pain. We retrospectively analyzed the CT findings of 83 women with right lower quadrant pain: PAI in 36 and PID in 47 patients. We reviewed the CT images, including the appendiceal diameter and the enhancing wall thickening, the cecal thickening, the location of the appendix, thickening of the right anterior renal fascia, abscess, mesenteric fatty infiltration, ascites, heterogeneous uterine enhancement and paralytic ileus. Statistical analysis was performed by using the t-test for the diameter of appendix, and the x 2 test or Fisher's exact test for the CT findings. The mean diameter of the appendix was 11.0 ± 3.4 mm for the PAI subjects and it was 6.7 ± 2.0 mm for the PID subjects (ρ < 0.0001). Wall thickening of the appendix was more commonly detected in PAI (25 subjects, 69%) than in PID (15 subjects, 32%) (ρ = 0.0007). Thickening of the right anterior renal fascia was more commonly detected in PAI (18 subjects, 50%) than in PID (7 subjects, 15%). Cecal thickening, ascitis, heterogeneous uterine enhancement and paralytic ileus were not significantly different between PAI and PID. Abscess and mesenteric fatty infiltration were more frequently detected in the RLQ and in the abdomen or pelvic cavity in PAI and PID, respectively (ρ < 0.05). There was no significant difference in the distribution of ascites between the diseases. The CT findings of the appendiceal diameter, enhancing wall thickening and thickening of the right anterior renal fascia are useful for making the diagnosis of PAI. The abdominal and pelvic distributions of abscess and mesenteric fatty infiltration are highly suggestive findings of PID

    Marek's disease (MD) outbreaks in poultry flocks may be associated with overriding of vaccine immune protection by very virulent (vvMDV) or very virulent plus (vv+MDV) strains. This paper presents the study on lymphoid organ morphology in the latent phase of MD caused by vv+MDV which break post-vaccinal protection in hens. We also immunohistochemically examined B and T populations as well as B/T and CD4+/CD8+ ratio of lymphocytes in lymphatic organs and, as a background, in MD lymphomas from non-lymphatic organs. The number of antigen expressed cells was evaluated as a percentage of positive cells in the one power field. Organ samples were collected from 24 dead reproductive hens (Ross 308 line) in age between 35-56 weeks, infected with vv+MDV. The hens originated from farms with MD outbreaks, despite earlier routine vaccination with CVI988/Rispens + HVT. The control organ samples originated from 15 clinically healthy hens at the same age and line, subjected to the same vaccination schedule. The number of CD3+, CD8+ and TCRγδ+ cells was significantly lower in MDV infected thymus, spleen and cecal tonsils in comparison to that found in the control organs. The proportion of CD4+ was also distinctly reduced in the thymus and limited in the spleen of MDV infected hens. This study revealed that infection with field vv+MDV isolates might break post-vaccinal protection and influence the central and peripheral immune system. The decrease in CD8+ and TCRγδ+ cell number in the thymus, spleen and cecal tonsils suggests that primarily these cells are involved in cell-mediated cytotoxicity against MDV transformed cells during latency.

  14. A rare case of an ACTH/CRH co-secreting midgut neuroendocrine tumor mimicking Cushing’s disease

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Ectopic ACTH/CRH co-secreting tumors are a very rare cause of Cushing’s syndrome and only a few cases have been reported in the literature. Differentiating between Cushing’s disease and ectopic Cushing’s syndrome may be particularly difficult if predominant ectopic CRH secretion leads to pituitary corticotroph hyperplasia that may mimic Cushing’s disease during dynamic testing with both dexamethasone and CRH as well as bilateral inferior petrosal sinus sampling (BIPSS. We present the case of a 24-year-old man diagnosed with ACTH-dependent Cushing’s syndrome caused by an ACTH/CRH co-secreting midgut NET. Both high-dose dexamethasone testing and BIPSS suggested Cushing’s disease. However, the clinical presentation with a rather rapid onset of cushingoid features, hyperpigmentation and hypokalemia led to the consideration of ectopic ACTH/CRH-secretion and prompted a further workup. Computed tomography (CT of the abdomen revealed a cecal mass which was identified as a predominantly CRH-secreting neuroendocrine tumor. To the best of our knowledge, this is the first reported case of an ACTH/CRH co-secreting tumor of the cecum presenting with biochemical features suggestive of Cushing’s disease.

  4. Association of Marek's Disease induced immunosuppression with activation of a novel regulatory T cells in chickens.

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Marek's Disease Virus (MDV is an alphaherpesvirus that infects chickens, transforms CD4+ T cells and causes deadly lymphomas. In addition, MDV induces immunosuppression early during infection by inducing cell death of the infected lymphocytes, and potentially due to activation of regulatory T (Treg-cells. Furthermore, immunosuppression also occurs during the transformation phase of the disease; however, it is still unknown how the disease can suppress immune response prior or after lymphoma formation. Here, we demonstrated that chicken TGF-beta+ Treg cells are found in different lymphoid tissues, with the highest levels found in the gut-associated lymphoid tissue (cecal tonsil: CT, fostering an immune-privileged microenvironment exerted by TGF-beta. Surprisingly, significantly higher frequencies of TGF-beta+ Treg cells are found in the spleens of MDV-susceptible chicken lines compared to the resistant line, suggesting an association between TGF-beta+ Treg cells and host susceptibility to lymphoma formation. Experimental infection with a virulent MDV elevated the levels of TGF-beta+ Treg cells in the lungs as early as 4 days post infection, and during the transformation phase of the disease in the spleens. In contrast to TGF-beta+ Treg cells, the levels of CD4+CD25+ T cells remained unchanged during the infection and transformation phase of the disease. Furthermore, our results demonstrate that the induction of TGF-beta+ Treg cells is associated with pathogenesis of the disease, as the vaccine strain of MDV did not induce TGF-beta+ Treg cells. Similar to human haematopoietic malignant cells, MDV-induced lymphoma cells expressed high levels of TGF-beta but very low levels of TGF-beta receptor I and II genes. The results confirm that COX-2/ PGE2 pathway is involved in immunosuppression induced by MDV-lymphoma cells. Taken together, our results revealed a novel TGF-beta+ Treg subset in chickens that is activated during MDV infection and tumour

    2015-01-01

    To document the quality of colonoscopy practice and the pattern of colonic disease including polyp detection rate at Shifa International Hospital, Islamabad, Pakistan. Study Design: An observational study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from May 2013 to June 2014. Methodology: This retrospective study recorded demographics of patients, indications and quality indices of 505 colonoscopies performed during the study period. Preparation was done with low residue diet and polyethylene glycol. Conscious sedation was generally used. Quality indices studied were compared with guideline standard. Results:Out of 505 colonoscopy patients, 305 were males and 200 were females. The indications for colonoscopic examination were lower gastrointestinal bleeding (26.5%, n=134), screening for colorectal cancer (14.1%, n=71), chronic diarrhea (12.9%, n=65), abdominal pain (10.9%, n=55), anemia (9.1%, n=46), constipation (7.3%, n=37), hematochezia and diarrhea (6.3%, n=32), altered bowel habits (5.1%, n=26), weight loss (3.6%, n=18), colonic thickening on CT scan (3.0%, n=15) and others (1.2%, n=6). Bowel preparation was adequate (in 92%, n=465) cases. Cecal intubation rate was 88.71% (n=448). Endoscopic diagnoses were hemorrhoids (36.2%, n=183), normal (22%, n=111), polyps (11.3%, n=57), ulcerative colitis (8.7%, n=44), cancer (4%, n=20), diverticulosis (3.4%, n=17), infective colitis (2.6%, n=13), intestinal TB (2.6%, n=13), non-specific colitis (2.2%, n=11), proctitis (1.8%, n=9) and others (5.3%, n=27). Conclusion: There is room for improvement in quality of colonoscopy, cecal intubation rate is slightly below the recommended standard and polyp detection rate is quite low however, it is not clear if the low rate of polyp detection is due to missed lesions or low population incidence. Time to reach caecum and withdrawal time should clearly be documented in the notes which can help to evaluate quality of the procedure in a better way

    Directory of Open Access Journals (Sweden)

    B K Naithani

    2015-01-01

    Full Text Available Intraoperative management of a known acute intermittent porphyria patient is a challenge requiring awareness of factors, which trigger an acute crisis, clinical features of a porphyric attack, knowledge of safe pharmacologic intervention, and preparedness for reintubation and ventilatory support. The classical signs of a porphyric crisis such as pain abdomen, vomiting and neuropsychiatric symptoms are masked under general anesthesia and can be confused with postoperative pain and vomiting and postoperative cognitive dysfunction, especially for intra-abdominal surgeries. Eternal vigilance for onset of an acute crisis is imperative. After a crisis of acute intermittent porphyria, residual paresis may persist for years in the absence of further attacks.

    Full Text Available Abstract Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection. We describe four cases that presented with symptoms suggestive of appendicitis, but were found at operation to have an inflamed solitary diverticulum.

    Full Text Available Dent disease is an x-linked disorder of proximal renal tubular dysfunction that occurs almost exclusively in males. It is characterized by significant, mostly low molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, and chronic kidney disease. Signs and symptoms of this condition appear in early childhood and worsen over time. There are two forms of Dent disease, which are distinguished by their genetic cause and pattern of signs and symptoms (type 1 and type 2. Dent disease 2 is characterized by the features described above and also associated with extrarenal abnormalities (they include mild intellectual disability, hypotonia, and cataract. Some researchers consider Dent disease 2 to be a mild variant of a similar disorder called Lowe syndrome.We represent a case of a 3-year old boy with significant proteinuria in the nephrotic range and hypercalciuria.

    Full Text Available Celiac disease is a multysystemic autoimmune disease induced by gluten in wheat, barley and rye. It is characterized by polygenic predisposition, high prevalence (1%, widely heterogeneous expression and frequent association with other autoimmune diseases, selective deficit of IgA and Down, Turner and Williams syndrome. The basis of the disease and the key finding in its diagnostics is symptomatic or asymptomatic inflammation of the small intestinal mucosa which resolves by gluten-free diet. Therefore, the basis of the treatment involves elimination diet, so that the disorder, if timely recognized and adequately treated, also characterizes excellent prognosis.

    Directory of Open Access Journals (Sweden)

    Holtmeier Wolfgang

    2006-03-01

    Full Text Available Abstract Celiac disease is a chronic intestinal disease caused by intolerance to gluten. It is characterized by immune-mediated enteropathy, associated with maldigestion and malabsorption of most nutrients and vitamins. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes. The main symptoms are: stomach pain, gas, and bloating, diarrhea, weight loss, anemia, edema, bone or joint pain. Prevalence for clinically overt celiac disease varies from 1:270 in Finland to 1:5000 in North America. Since celiac disease can be asymptomatic, most subjects are not diagnosed or they can present with atypical symptoms. Furthermore, severe inflammation of the small bowel can be present without any gastrointestinal symptoms. The diagnosis should be made early since celiac disease causes growth retardation in untreated children and atypical symptoms like infertility or neurological symptoms. Diagnosis requires endoscopy with jejunal biopsy. In addition, tissue-transglutaminase antibodies are important to confirm the diagnosis since there are other diseases which can mimic celiac disease. The exact cause of celiac disease is unknown but is thought to be primarily immune mediated (tissue-transglutaminase autoantigen; often the disease is inherited. Management consists in life long withdrawal of dietary gluten, which leads to significant clinical and histological improvement. However, complete normalization of histology can take years.

    Although the prevalence of dementia continues to increase worldwide, incidence in the western world might have decreased as a result of better vascular care and improved brain health. Alzheimer's disease, the most prevalent cause of dementia, is still defined by the combined presence of amyloid and tau, but researchers are gradually moving away from the simple assumption of linear causality as proposed in the original amyloid hypothesis. Age-related, protective, and disease-promoting factors probably interact with the core mechanisms of the disease. Amyloid β42, and tau proteins are established core cerebrospinal biomarkers; novel candidate biomarkers include amyloid β oligomers and synaptic markers. MRI and fluorodeoxyglucose PET are established imaging techniques for diagnosis of Alzheimer's disease. Amyloid PET is gaining traction in the clinical arena, but validity and cost-effectiveness remain to be established. Tau PET might offer new insights and be of great help in differential diagnosis and selection of patients for trials. In the search for understanding the disease mechanism and keys to treatment, research is moving increasingly into the earliest phase of disease. Preclinical Alzheimer's disease is defined as biomarker evidence of Alzheimer's pathological changes in cognitively healthy individuals. Patients with subjective cognitive decline have been identified as a useful population in whom to look for preclinical Alzheimer's disease. Moderately positive results for interventions targeting several lifestyle factors in non-demented elderly patients and moderately positive interim results for lowering amyloid in pre-dementia Alzheimer's disease suggest that, ultimately, there will be a future in which specific anti-Alzheimer's therapy will be combined with lifestyle interventions targeting general brain health to jointly combat the disease. In this Seminar, we discuss the main developments in Alzheimer's research. Copyright © 2016 Elsevier Ltd. All

    Full Text Available Celiac disease also known as gluten-sensitive enteropathy is characterized by intestinal mucosal damage and malabsorption from dietary intake of wheat, rye or barley. Symptoms may appear with introduction of cereal in the first 3 years of life. A second peak in symptoms occurs in adults during the third or forth decade and even as late as eight decade of life. The prevalence of this disease is approximately 1 in 250 adults. The disease is more prevalent in Ireland as high as 1 in 120 adults. The disorder occurs in Arab, Hispanics, Israeli Jews, Iranian and European but is rare in Chinese and African American. To have celiac disease the patient should have the celiac disease genetic markers as HLA DQ 2 and HLA DQ 8. Patient with celiac disease may have 95 per cent for DQ 2 and the rest is by DQ 8. Someone may have the genetic marker and never develops the disease. In general 50 percent with markers may develop celiac disease. To develop the disease the gene needs to become activated. This may happen with a viral or bacterial infection, a surgery, delivery, accident, or psychological stress. After activation of gene cause the tight junction to opens with the release of Zonulin This results in passage of gluten through the tight junction and formation of multiple antibodies and autoimmune disease. This also allows entrance of other proteins and development of multiple food allergies. As a result is shortening, flattening of intestinal villi resulting in food, vitamins and minerals malabsorption.

    Crohn\\'s disease is a disorder mediated by T lymphocytes which arises in genetically susceptible individuals as a result of a breakdown in the regulatory constraints on mucosal immune responses to enteric bacteria. Regulation of immune reactivity to enteric antigens has improved understanding of the pathophysiological mechanisms of Crohn\\'s disease, and has expanded therapeutic options for patients with this disorder. Disease heterogeneity is probable, with various underlying defects associated with a similar pathophysiological outcome. Although most conventional drug treatments are directed at modification of host response, therapeutic manipulation of the enteric flora is becoming a realistic option.

    Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

    2000-08-01

    Infectious bursal disease (IBD) (Gumboro disease) has been described throughout the world, and the socio-economic significance of the disease is considerable world-wide. Various forms of the disease have been described, but typing remains unclear, since antigenic and pathotypic criteria are used indiscriminately, and the true incidence of different types is difficult to determine. Moreover, the infection, when not fatal, leads to a degree of immunosuppression which is often difficult to measure. Finally, the control measures used are subject to variations, and seldom follow a specific or standardised plan. In the context of expanding international trade, the authors provide an overview of existing knowledge on the subject to enhance available information on the epidemiology of IBD, the identification of reliable viral markers for diagnosis, and the implementation of specific control measures to ensure a global and co-ordinated approach to the disease.

    Crohn's disease is a chronic inflammatory bowel disease of unknown etiology associated with an impaired immune response, with periods of activity and remission. It is characterised by patchy and transmural lesions which can affect the entire gastrointestinal tract, from the mouth to the anus. The most frequent symptoms are abdominal pain and diarrhoea, which can seriously affect patients' quality of life. The increasing incidence and prevalence of the disease in our area has had a large impact on clinical practice, with the rapid development of diagnostic and therapeutic techniques. To reduce the risk of complications, primary care physicians and gastroenterologists should be familiar with the management of the disease. Copyright © 2017 Elsevier España, S.L.U.

    Fabry disease, also known as Anderson-Fabry disease or angiokeratoma corporis diffusum universale, is an X-linked recessive form of sphingolipidosis caused by total or partial deficiency of the lysosomal hydrolase, alpha-galactosidase A. From the youngest age, it results in a gradual ubiquitous build-up of glycosphingolipids that are not degraded by the missing enzyme. Cutaneous, neurological, nephrologic, cardiac, gastrointestinal, ophthalmological, respiratory, cochleovestibular and haematological involvement are responsible for increased mortality and significant impairment of quality of life in subjects affected by the disease. Angiokeratomas are the most common cutaneous sign of this disease, although they are not specific to it and must be distinguished from angiokeratomas either occurring in isolation or associated with systemic diseases. Other cutaneous signs encountered in this disease include hyperhidrosis, oral lesions, lower limb oedemas, etc. The diagnosis is mainly clinical and should be considered in the presence of a personal and/or familial history; it is confirmed by assay of enzyme activity within leucocytes or by molecular studies. Management is multidisciplinary and involves symptomatic treatment as well as specific treatment, resulting in improved survival and enhanced quality of life for patients presenting the disease. Enzyme replacement therapy with alpha-galactosidase A forms the cornerstone of specific treatment and may be associated with other types of treatments such as galactose and molecular chaperones. Gene therapy is now also used extensively. At present, these marked therapeutic advances, which closely involve dermatologists, could help transform the prognosis for patients presenting Fabry disease. Copyright © 2016 Elsevier Masson SAS.

    2014-01-01

    Full Text Available In accordance with the current definition proposed by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN in 2012, celiac disease is regarded as an immune-mediated systemic disease caused by gluten and respective prola-mins in genetically predisposed people. Detailed studies of the pathogenesis of gluten enteropathy provided the basis for investigating the possible causes of the common concurrence of celiac disease with a number of autoimmune and endocrine diseases. The possible reasons for the association are considered to be common genetic markers in the patients, a cross reaction of the autoantibodies formed in celiac disease and activated T lymphocytes with the body's intrinsic antigens, as well as the systemic action of proinflam-matory cytokines. Although many issues of pathophysiology remain a matter of debate, the fact that patients suffering from a number of diseases form a group at risk for celiac disease and require a careful follow-up and examination for timely diagnosis and use of gluten-free diet is currently beyond question.

    2006-01-01

    Fabry's disease is a rare X-linked, recessive, glycolipid storage disorder. It is caused by the deficient activity of a lysosomal enzyme, alpha-galactosidase A. Deficiency of alpha-GAL causes an inability to catabolize the lipids with cellular accumulation of its most abundant substrate, globotriaosylceramide (GL-3), and other neutral glycosphingolipids in the vascular endothelium and numerous tissues throughout the body. This progressive glycosphingolipid accumulation leads to life-threatening clinical sequelae in renal, cardiac and cerebrovascular systems. Heterozygous Fabry's disease is less studied. We present a patient, 43 years old, with cardiac (hypertrophic cardiomyopathy), neurological (sensitive-motive polyneuropathy), digestive (chronic diarrheea), renal and cutaneous involvements.

    2013-09-01

    Full Text Available Prion diseases are neurodegenerative illnesses due to the accumulation of small infectious pathogens containing protein but apparently lacking nucleic acid, which have long incubation periods and progress inexorably once clinical symptoms appear. Prions are uniquely resistant to a number of normal decontaminating procedures. The prionopathies [Kuru, Creutzfeldt-Jakob disease (CJD and its variants, Gerstmann-Sträussler-Scheinker (GSS syndrome and fatal familial insomnia (FFI] result from accumulation of abnormal isoforms of the prion protein in the brains of normal animals on both neuronal and non-neuronal cells. The accumulation of this protein or fragments of it in neurons leads to apoptosis and cell death. There is a strong link between mutations in the gene encoding the normal prion protein in humans (PRNP - located on the short arm of chromosome 20 – and forms of prion disease with a familial predisposition (familial CJD, GSS, FFI. Clinically a prionopathy should be suspected in any case of a fast progressing dementia with ataxia, myoclonus, or in individuals with pathological insomnia associated with dysautonomia. Magnetic resonance imaging, identification of the 14-3-3 protein in the cerebrospinal fluid, tonsil biopsy and genetic studies have been used for in vivo diagnosis circumventing the need of brain biopsy. Histopathology, however, remains the only conclusive method to reach a confident diagnosis. Unfortunately, despite numerous treatment efforts, prionopathies remain short-lasting and fatal diseases.

    Full Text Available Newcastle disease (ND, caused by virulent strains of Newcastle disease virus (NDV, is a highly contagious disease of birds that is responsible for heavy economic losses for the poultry industry worldwide. However, little is known about host-virus interactions in waterfowl, goose. In this study, we aim to characterize the host immune response in goose, based on the previous reports on the host response to NDV in chickens. Here, we evaluated viral replication and mRNA expression of 27 immune-related genes in 10 tissues of geese challenged with a genotype VIId NDV strain of goose origin (go/CH/LHLJ/1/06. The virus showed early replication, especially in digestive and immune tissues. The expression profiles showed up-regulation of Toll-like receptor (TLR1–3, 5, 7 and 15, avian β-defensin (AvBD 5–7, 10, 12 and 16, cytokines interleukin (IL-8, IL-18, IL-1β and interferon-γ, inducible NO synthase (iNOS, and MHC class I in some tissues of geese in response to NDV. In contrast, NDV infection suppressed expression of AvBD1 in cecal tonsil of geese. Moreover, we observed a highly positive correlation between viral replication and host mRNA expressions of TLR1-5 and 7, AvBD4-6, 10 and 12, all the cytokines measured, MHC class I, FAS ligand, and iNOS, mainly at 72 h post-infection. Taken together, these results demonstrated that NDV infection induces strong innate immune responses and intense inflammatory responses at early stage in goose which may associate with the viral pathogenesis.

    Full Text Available Susceptibility of ostriches (Struthio camelus to the Indonesian velogenic strain of Newcastle disease virus (NDV was evaluated by artificial infection . Twelve - 5 to 6 week old ostriches were divided into 3 groups each containing 4 birds . The first group was inoculated through respiratory system by dropping directly the virus solution into the nostrils, while the second group was inoculated through digestive system by dropping directly the virus solution into the oesophagus, with the dose of infection 106ELDSo (50%-embryo lethal dose per bird . Meanwhile, the third group was treated as uninfected control . All infected birds developed antibody responses, but only two inoculated birds from the first group and two inoculated birds from the second group developed clinical signs of Newcastle disease (ND, with no specific pathological alterations . Infected birds, either sicks or healthy, excreted the challenge viruses through the respiratory system and still be detected up to the end of this experiment, ie . 15 days post-inoculation . The challenge viruses can be re-isolated from the brain, trachea, lungs, heart, liver, spleen, kidneys, small intestine, cecal-tonsil, and proventriculus of the infected birds . This study concludes that: (1 the ostriches are susceptible to the infection of the Indonesian velogenic strain ofNDV; (2 all infected birds developed immune responses, but only half of them develops el jtigi aj i disease ; (3 the infected birds excreted the challenge viruses for a considerable long time which may play role as the Mginiseti.ce ofinfectron the other healthy ostriches ; and (4 the challenge viruses can be re-isolated from various organs of the birds . .

    Full Text Available Abstract Fabry disease (FD is a progressive, X-linked inherited disorder of glycosphingolipid metabolism due to deficient or absent lysosomal α-galactosidase A activity. FD is pan-ethnic and the reported annual incidence of 1 in 100,000 may underestimate the true prevalence of the disease. Classically affected hemizygous males, with no residual α-galactosidase A activity may display all the characteristic neurological (pain, cutaneous (angiokeratoma, renal (proteinuria, kidney failure, cardiovascular (cardiomyopathy, arrhythmia, cochleo-vestibular and cerebrovascular (transient ischemic attacks, strokes signs of the disease while heterozygous females have symptoms ranging from very mild to severe. Deficient activity of lysosomal α-galactosidase A results in progressive accumulation of globotriaosylceramide within lysosomes, believed to trigger a cascade of cellular events. Demonstration of marked α-galactosidase A deficiency is the definitive method for the diagnosis of hemizygous males. Enzyme analysis may occasionnally help to detect heterozygotes but is often inconclusive due to random X-chromosomal inactivation so that molecular testing (genotyping of females is mandatory. In childhood, other possible causes of pain such as rheumatoid arthritis and 'growing pains' must be ruled out. In adulthood, multiple sclerosis is sometimes considered. Prenatal diagnosis, available by determination of enzyme activity or DNA testing in chorionic villi or cultured amniotic cells is, for ethical reasons, only considered in male fetuses. Pre-implantation diagnosis is possible. The existence of atypical variants and the availability of a specific therapy singularly complicate genetic counseling. A disease-specific therapeutic option - enzyme replacement therapy using recombinant human α-galactosidase A - has been recently introduced and its long term outcome is currently still being investigated. Conventional management consists of pain relief with

    Peyronie disease, or Induratio Penis Plastica, is characterized by the presence of one or more fibrous plaques at the albuginea penis, on the cavernous bodies or on the intercavernous septum. First of all, Induratio Penis Plastica ethiology is described, and its clincs and therapy. Past imaging methods are then considered (i.e. conventional radiology, cavernosography, CT and US). The authors report on their 4-year (1983-1987) experience with US in 62 males. Various different probes were employed, especially small-part 7.5 MHz probes. The results are similar to those reported in international literature. The use of high frequency probes allow the evaluation of local hypoechoic lesions even in the early phase of the disease, thus helping make therapy more effective

    2008-01-01

    Morgellons disease, a pattern of dermatologic symptoms very similar, if not identical, to those of delusions of parasitosis, was first described many centuries ago, but has recently been given much attention on the internet and in the mass media. The present authors present a history of Morgellons disease, in addition to which they discuss the potential benefit of using this diagnostic term as a means of building trust and rapport with patients to maximize treatment benefit. The present authors also suggest "meeting the patient halfway" and creating a therapeutic alliance when providing dermatologic treatment by taking their cutaneous symptoms seriously enough to provide both topical ointments as well as antipsychotic medications, which can be therapeutic in these patients.

    The history of Lyme disease, a contagious condition caused by Borrelia burgdorferi transmitted to man by ticks offers infectiologists a formidable lesson on how medicine progresses. Clinical description started in Europe at the turn of the century with Pick's description of what was then labelled chronic atrophic acrodermatitis. Fifty years later Hauser noted the affection was transmitted by ticks. Independently, Afzelius, then Lipschutz, described erythema chronicum migrans and its relationship with tick bites. Neurological involvement was also described with the skin signs. These early dermatological descriptions suddenly came into the limelight in 1975 when an epidemia of arthritis occurred in children in Lyme, Connecticut, USA. Many of the affected children had erythema chronicum migrans. Based on these observations and an epidemiological analysis of the epidemia, Steele and co-workers defined "Lyme disease" as a rheumatological disorder commonly associated with erythema chronicum migrans and sometimes with multiple organ involvement. In 1982 Borgdorfer suggested that tick bites transmitted a Spirochaeta which was later authentified as the causal agent: Borrelia burgdorferi. Immunofluorescence and ELISA tests were rapidly developed for the diagnosis of infection by this germ which is very difficult to culture. Antibiotic curative treatment was immediately available and in 1991 a consensus conference established recommendations for treatment of isolated and disseminated forms. Antibiotic prophylaxis is not necessary but rapid extraction of the tick after the bite can prevent the disease as transmission from tick to man takes several hours. And medical progress continues. Work is now being conducted on evaluating the extent of late neurological manifestations, on developing polymerase chain reaction methods to identify B. burgdorferi infection in specific organs and on developing a vaccine.

    This chapter reviews the correlation between thyroid disease, other than cancer, and radiation in the literature. Radiation-induced thyroid disturbance is discussed in the context of external and internal irradiation. External irradiation of 10 to 40 Gy may lower thyroid function several months or years later. Oral administration of I-131 is widely given to patients with Basedow's disease; it may also lower thyroid function with increasing radiation doses. When giving 70 Gy or more of I-131, hypothyroidism has been reported to occur in 20-30% and at least 10%. Thyroiditis induced with internal I-131 irradiation has also been reported, but no data is available concerning external irradiation-induced thyroiditis. The incidence of nodular goiter was found to be several ten times higher with external irradiation than internal irradiation. Thyroid disturbance is correlated with A-bomb survivors. A-bomb radiation can be divided into early radiation within one minute after A-bombing and the subsequent residual radiation. Nodular goiter was significantly more frequent in the exposed group than the non-exposed group; it increased with increasing radiation doses and younger age (20 years or less) at the time of exposure. The incidence of decrease in thyroid function was higher with increasing radiation doses. However, in the case of Nagasaki, the incidence of hypothyroidism was significantly higher in the low-dose exposed group, especially A-bomb survivors aged 10-39 at the time of exposure and women.

    A 66 years female, who was since last year under astenia, arthralgias, pimply lesions in spread plates and tests showing eritrosedimentation over 100 mm, anemi, leucocitosis with neutrofilia, policlonal hypergammaglobulinemia, slight proteinuria and IgE on 900. This patient was sporadically treated with corticoids. When made the medical consult had lost 34lb., was under anorexy, as well as dyspepsia. Hemoglobyn 6.9 gr/dl, leucocytes 20000/mm3, neutrofils at 90%, proteinogram the same as former, with hypoalbuminemia. She was taking prednisona, 16 mg/day. When examined showed depress of conscience, astenia, and dermic lesions already quoted. 4 cm nonpainful right axillary adenopaty adhered to deep planes. Medulogram with increased iron, hyperegenerative. Ganglionar biopsia: linfoid hyperplasic process linked to inmune response. Toracoabdominal tomography with adenomegalia in torax and retroperitoneo. Skin biopsia: neutrofilic vasculitis. The patient suspends the 16 mg of prednisona and fever as well as generalized adenopatias come up. After laying aside other ethiologies, and understanding as Castleman Multicentric disease, it is started to supply prednisona 1 mg/kg of weight with a clinical and biochemical fast and outstanding response. After 7 months it was progressively suspended the esteroids and 60 days later, the process fall back; for that, corticoids are restarted, with a good evolution. The illness of Castleman although it is not very frequent, it should be considered as differential diagnosis in those clinical cases that are accompanied with important general commitment, linphadenopaties and respons to steroid therapy.

    Osler's disease, also known as hereditary hemorrhagic telangiectasia (HHT) and Osler-Weber-Rendu syndrome, is an autosomal dominant disorder leading to abnormal blood vessel formation in the skin, mucous membranes and often in organs, such as the lungs, liver and brain (arteriovenous malformations AVM). Various types are known. Patients may present with epistaxis. Teleangiectasia can be identified by visual inspection during physical examination of the skin or oral cavity or by endoscopy. Diagnosis is made after clinical examination and genetic testing based on the Curacao criteria. Modern imaging modalities, such as computed tomography (CT) or magnetic resonance imaging (MRI) have become more important as they can depict the AVMs. Pulmonary AVMs can be depicted in CT imaging even without the use of a contrast agent while other locations including the central nervous system (CNS) usually require administration of contrast agents. Knowledge of possible clinical manifestations in various organs, possible complications and typical radiological presentation is mandatory to enable adequate therapy of these patients. Interventional procedures are becoming increasingly more important in the treatment of HHT patients. (orig.) [de

    Understanding how dietary components alter the healthy baseline colonic microenvironment is important in determining their roles in influencing gut health and gut-associated diseases. Dietary flaxseed (FS) has demonstrated anti-colon cancer effects in numerous rodent models, however, exacerbated acute colonic mucosal injury and inflammation in a colitis model. This study investigates whether FS alters critical aspects of gut health in healthy unchallenged mice, which may help explain some of the divergent effects observed following different gut-associated disease challenges. Four-week-old C57Bl/6 male mice were fed an AIN-93G basal diet (BD) or an isocaloric BD+10% ground FS diet for 3 weeks. FS enhanced colon goblet cell density, mucus production, MUC2 mRNA expression, and cecal short chain fatty acid levels, indicative of beneficial intestinal barrier integrity responses. Additionally, FS enhanced colonic regenerating islet-derived protein 3 gamma (RegIIIγ) and reduced MUC1 and resistin-like molecule beta (RELMβ) mRNA expression which may indicate altered responses in regulating microbial defense and injury repair responses. FS diet altered the fecal microbial community structure (16S rRNA gene profiling), including a 20-fold increase in Prevotella spp. and a 30-fold reduction in Akkermansia muciniphila abundance. A 10-fold reduction in A. muciniphila abundance by FS was also demonstrated in the colon tissue-associated microbiota (quantitative PCR). Furthermore, fecal branched chain fatty acids were increased by FS, indicative of increased microbial-derived putrefactive compounds. In conclusion, consumption of a FS-supplemented diet alters the baseline colonic microenvironment of healthy mice which may modify subsequent mucosal microbial defense and injury-repair responses leading to altered susceptibility to different gut-associated diseases.

    A-bombing panicked many people with anxiety because they suffered from various symptoms after A-bombing (ie, they generally called them A-bomb disease). In this chapter, major two conditions (ie, leukopenia and anemia), which caused their symptoms, are reviewed based on the early data soon after A-bombing. According to the chronological changes in both white blood cell (WBC) and red blood cell (RBC) counts, both leukopenia and anemia are discussed. The findings can be divided into acute (one week or at least 10 days), subacute (2 weeks to one month), and delayed (thereafter) periods. During an acute period, some exposed even at ≤200 m from the hypocenter showed WBC count of 6,000/mm 3 or more one week after exposure but others exposed at 1,500-2,000 m showed WBC count of less than 3,000/mm 3 , suggesting the influence of shielding on WBC count. WBC count sometimes became the lowest during a subacute period, although it was normal during an acute period. A survey for WBC count during a delayed period (one year later) showed that WBC count of less than 4,000/mm 3 was more frequent in the exposed group (78/523 A-bomb survivors, 14.9%) than the non-exposed group (6/173 persons, 3.5%). In the exposed group, leukopenia was independent of distance and symptoms at the time of exposure. For anemia, there was no data available during an acute period. Anemia frequently occurred during a subacute period. Morphological abnormality of RBC tended to be high in death cases. A delayed survey on anemia 10 years after exposure showed that there was no statistically significant difference in any of the factors, such as hemoglobin, RBC count, hematocrit, mean corpuscular volume and mean corpuscular hemoglobin, between the exposed and non-exposed groups.

    Full Text Available Alzheimer Disease (AD is an outcome as well as source of many diseases. Alzheimer is linked with many other diseases like Diabetes type 2, cholesterolemia, hypertension and many more. But how each of these diseases affecting other is still unknown to scientific community. Signaling Pathways of one disease is interlinked with other disease. But to what extent healthy brain is affected when any signaling in human body is disturbed is the question that matters. There is a need of Pathway analysis, Protein-Protein interaction (PPI and the conserved interactome study in AD and linked diseases. It will be helpful in finding the potent drug or vaccine target in conscious manner. In the present research the Protein-Protein interaction of all the proteins involved in Alzheimer Disease is analyzed using ViSANT and osprey tools and pathway analysis further reveals the significant genes/proteins linking AD with other diseases.

    Cardiovascular disease is increasingly recognized as a major cause of premature mortality among those with autoimmune disorders. There is an urgent need to identify those patients with autoimmune disease who are at risk for CVD so as to optimize therapeutic intervention and ultimately prevention. Accurate identification, monitoring and stratification of such patients will depend upon a panel of biomarkers of cardiovascular disease. This review will discuss some of the most recent biomarkers of cardiovascular diseases in autoimmune disease, including lipid oxidation, imaging biomarkers to characterize coronary calcium, plaque, and intima media thickness, biomarkers of inflammation and activated complement, genetic markers, endothelial biomarkers, and antiphospholipid antibodies. Clinical implementation of these biomarkers will not only enhance patient care but also likely accelerate the pharmaceutical pipeline for targeted intervention to reduce or eliminate cardiovascular disease in the setting of autoimmunity.

    DNA methylation and histone modifications determine renal programming and the development and progression of renal disease. The identification of the way in which the renal cell epigenome is altered by environmental modifiers driving the onset and progression of renal diseases has extended our understanding of the pathophysiology of kidney disease progression. In this review, we focus on current knowledge concerning the implications of epigenetic modifications during renal disease from early development to chronic kidney disease progression including renal fibrosis, diabetic nephropathy and the translational potential of identifying new biomarkers and treatments for the prevention and therapy of chronic kidney disease and end-stage kidney disease.

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

    2008-01-01

    Crohn's disease is a chronic inflammatory disease that can affect any part of the gastrointestinal tract. Classically the disease has a predilection for the distal small bowel and colon and presents with dominant symptoms of abdominal pain and diarrhea. This case report describes a 38-year-old woman with Crohn's disease who presented with odynophagia. Direct visualization of the oropharynx revealed a large serpiginous Crohn's disease ulcer. A precipitous drop in hemoglobin prompted a series of gastroenterologic investigations that confirmed both ileal and oropharyngeal Crohn's disease. This manuscript describes the presentation of oropharyngeal Crohn's and reviews previous reports and management options.

  5. Nonalcoholic fatty liver disease - A multisystem disease?

    Non-alcoholic fatty liver disease (NAFLD) is one of the most common comorbidities associated with overweight and metabolic syndrome (MetS). Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of MetS. However, accumulating evidence indicates that the effects of NAFLD extend beyond the liver and are negatively associated with a range of chronic diseases, most notably cardiovascular disease (CVD), diabetes mellitus type 2 (T2DM) and chronic kidney disease (CKD). It is becoming increasingly clear that these diseases are the result of the same underlying pathophysiological processes associated with MetS, such as insulin resistance, chronic systemic inflammation and dyslipidemia. As a result, they have been shown to be independent reciprocal risk factors. In addition, recent data have shown that NAFLD actively contributes to aggravation of the pathophysiology of CVD, T2DM, and CKD, as well as several other pathologies. Thus, NAFLD is a direct cause of many chronic diseases associated with MetS, and better detection and treatment of fatty liver disease is therefore urgently needed. As non-invasive screening methods for liver disease become increasingly available, detection and treatment of NAFLD in patients with MetS should therefore be considered by both (sub-) specialists and primary care physicians.

  6. Intestinal Metabolites Are Profoundly Altered in the Context of HLA-B27 Expression and Functionally Modulate Disease in a Rat Model of Spondyloarthritis.

    HLA-B27-associated spondyloarthritides are associated with an altered intestinal microbiota and bowel inflammation. We undertook this study to identify HLA-B27-dependent changes in both host and microbial metabolites in the HLA-B27/β 2 -microglobulin (β 2 m)-transgenic rat and to determine whether microbiota-derived metabolites could impact disease in this major model of spondyloarthritis. Cecal contents were collected from Fischer 344 33-3 HLA-B27/β 2 m-transgenic rats and wild-type controls at 6 weeks (before disease) and 16 weeks (with active bowel inflammation). Metabolomic profiling was performed by high-throughput gas and liquid chromatography-based mass spectrometry. HLA-B27/β 2 m-transgenic rats were treated with the microbial metabolites propionate or butyrate in drinking water for 10 weeks, and disease activity was subsequently assessed. Our screen identified 582 metabolites, of which more than half were significantly altered by HLA-B27 expression at 16 weeks. Both microbial and host metabolites were altered, with multiple pathways affected, including those for amino acid, carbohydrate, xenobiotic, and medium-chain fatty acid metabolism. Differences were even observed at 6 weeks, with up-regulation of histidine, tyrosine, spermidine, N-acetylmuramate, and glycerate in HLA-B27/β 2 m-transgenic rats. Administration of the short-chain fatty acid propionate significantly attenuated HLA-B27-associated inflammatory disease, although this was not associated with increased FoxP3+ T cell induction or with altered expression of the immunomodulatory cytokines interleukin-10 (IL-10) or IL-33 or of the tight junction protein zonula occludens 1. HLA-B27 expression was also associated with altered host expression of messenger RNA for the microbial metabolite receptors free fatty acid receptor 2 (FFAR2), FFAR3, and niacin receptor 1. HLA-B27 expression profoundly impacts the intestinal metabolome, with changes evident in rats even at age 6 weeks. Critically, we

  11. Glomerular Disease in Women

    Directory of Open Access Journals (Sweden)

    Kate Wiles

    2018-03-01

    Full Text Available Gender differences exist in the prevalence of glomerular diseases. Data based on histological diagnosis underestimate the prevalence of preeclampsia, which is almost certainly the commonest glomerular disease in the world, and uniquely gender-specific. Glomerular disease affects fertility via disease activity, the therapeutic use of cyclophosphamide, and underlying chronic kidney disease. Techniques to preserve fertility during chemotherapy and risk minimization of artificial reproductive techniques are considered. The risks, benefits, and effectiveness of different contraceptive methods for women with glomerular disease are outlined. Glomerular disease increases the risk of adverse outcomes in pregnancy, including preeclampsia; yet, diagnosis of preeclampsia is complicated by the presence of hypertension and proteinuria that precede pregnancy. The role of renal biopsy in pregnancy is examined, in addition to the use of emerging angiogenic biomarkers. The safety of drugs prescribed for glomerular disease in relation to reproductive health is detailed. The impact of both gender and pregnancy on long-term prognosis is discussed.

  12. Emerging noninfectious diseases

    Directory of Open Access Journals (Sweden)

    Ezequiel Consiglio

    Full Text Available In recent years, emerging diseases were defined as being infectious, acquiring high incidence, often suddenly, or being a threat or an unexpected phenomenon. This study discusses the hallmarks of emerging diseases, describing the existence of noninfectious emerging diseases, and elaborating on the advantages of defining noninfectious diseases as emerging ones. From the discussion of various mental health disorders, nutritional deficiencies, external injuries and violence outcomes, work injuries and occupational health, and diseases due to environmental factors, the conclusion is drawn that a wide variety of noninfectious diseases can be defined as emergent. Noninfectious emerging diseases need to be identified in order to improve their control and management. A new definition of "emergent disease" is proposed, one that emphasizes the pathways of emergence and conceptual traits, rather than descriptive features.

It has also been called acid maltase deficiency and glycogen storage disease type II. There is a broad clinical presentation: the most severe form that presents in the first few months of life with cardiomyopathy and generalized muscle weakness that rapidly progresses to death from cardio-respiratory failure in the first year of life (infant-onset Pompe disease. A more slowly progressive disease, with little or no cardiac involvement, presents with proximal myopathy and/or pulmonary insufficiency, from the second year of life to late adulthood (late-onset Pompe disease. The recent development and introduction of enzyme replacement therapy with intravenous infusion of recombinant human acid alpha-glucosidase have made a major improvement in the morbidity and mortality of this disease. New therapies are also in development. With the availability of treatment, diagnostic methods have also improved, allowing for earlier recognition and potential early therapeutic intervention. The advent of newborn screening for Pompe disease may identify patients who can be treated before significant irreversible disease has occurred.

    Full Text Available Laura Ghezzi, Elio Scarpini, Daniela Galimberti Neurology Unit, Department of Pathophysiology and Transplantation, University of Milan, Fondazione Cà Granda, IRCCS Ospedale Maggiore Policlinico, Milan, Italy Abstract: Alzheimer's disease (AD is an age-dependent neurodegenerative disorder and the most common cause of dementia. The early stages of AD are characterized by short-term memory loss. Once the disease progresses, patients experience difficulties in sense of direction, oral communication, calculation, ability to learn, and cognitive thinking. The median duration of the disease is 10 years. The pathology is characterized by deposition of amyloid beta peptide (so-called senile plaques and tau protein in the form of neurofibrillary tangles. Currently, two classes of drugs are licensed by the European Medicines Agency for the treatment of AD, ie, acetylcholinesterase inhibitors for mild to moderate AD, and memantine, an N-methyl-D-aspartate receptor antagonist, for moderate and severe AD. Treatment with acetylcholinesterase inhibitors or memantine aims at slowing progression and controlling symptoms, whereas drugs under development are intended to modify the pathologic steps leading to AD. Herein, we review the clinical features, pharmacologic properties, and cost-effectiveness of the available acetylcholinesterase inhibitors and memantine, and focus on disease-modifying drugs aiming to interfere with the amyloid beta peptide, including vaccination, passive immunization, and tau deposition.

    Although our current understanding is limited, epidemiologic investigation of Crohn's disease holds great promise. Certain aspects of the epidemiology are clear. The incidence of Crohn's disease, which has increased over the past few decades, may have reached a plateau. The disease has its peak onset in early life, with a second peak among the elderly. It is more common in the developed countries and among Jews. Whether the disease is related to occupation, social class, marital status, stress, infection, diet, smoking, and oral contraceptives is less certain. This paper reviews the epidemiology of Crohn's disease and proposes areas in which further research is needed.

Classically, hyperpigmentation is associated with the disease, and intraoral pigmentation is perceived as the initial sign and develops earlier than the dermatological pigmentation. The symptoms of the disease usually progress slowly and an event of illness or accident can make the condition worse and may lead to a life-threatening crisis. In this case, several oral as well as systemic manifestation of the Addison′s disease was encountered.

    The application of CT to the evaluation of inflammatory disease of the small bowel and colon has evolved in parallel with the development of scanners with shorter scan times and higher resolution and with increasing sophistication of the radiologist in the use of this imaging technique. Although high-quality barium studies remain the examination of choice for the demonstration of mucosal disease, CT is now considered the gold standard for evaluating the extraluminal components of the disease process. This chapter reviews the typical CT findings and possible complications of Crohn's disease and discusses the potential impact of CT on the clinical management of the patient with Crohn's disease

    2015-09-01

    Coeliac disease is a chronic autoimmune enteropathy, which is caused by exposure to dietary gluten in genetically pre-disposed individuals. -Approximately 0.5-1% of the Dutch population has coeliac disease, diag-nosed at both younger and older age. Treatment consists of a strict gluten-free diet. Symptoms can be diverse, including dental and oral manifestations. These dental and oral manifestations are often seen in patients with coeliac disease, although most of them are nonspecific. This is not the case for the symmetric enamel defects described by Aine and colleagues, which are very specific for coeliac disease. Early diagnosing of coeliac disease is important to prevent complications by (vitamin) deficiencies or rare (pre) malignant forms of coeliac disease. There seems to be a role for dentists in early diagnosing of coeliac disease.

  1. Celiac disease and autoimmune thyroid disease.

    Science.gov (United States)

    Ch'ng, Chin Lye; Jones, M Keston; Kingham, Jeremy G C

    2007-10-01

    Celiac disease (CD) or gluten sensitive enteropathy is relatively common in western populations with prevalence around 1%. With the recent availability of sensitive and specific serological testing, many patients who are either asymptomatic or have subtle symptoms can be shown to have CD. Patients with CD have modest increases in risks of malignancy and mortality compared to controls. The mortality among CD patients who comply poorly with a gluten-free diet is greater than in compliant patients. The pattern of presentation of CD has altered over the past three decades. Many cases are now detected in adulthood during investigation of problems as diverse as anemia, osteoporosis, autoimmune disorders, unexplained neurological syndromes, infertility and chronic hypertransaminasemia of uncertain cause. Among autoimmune disorders, increased prevalence of CD has been found in patients with autoimmune thyroid disease, type 1 diabetes mellitus, autoimmune liver diseases and inflammatory bowel disease. Prevalence of CD was noted to be 1% to 19% in patients with type 1 diabetes mellitus, 2% to 5% in autoimmune thyroid disorders and 3% to 7% in primary biliary cirrhosis in prospective studies. Conversely, there is also an increased prevalence of immune based disorders among patients with CD. The pathogenesis of co-existent autoimmune thyroid disease and CD is not known, but these conditions share similar HLA haplotypes and are associated with the gene encoding cytotoxic T-lymphocyte-associated antigen-4. Screening high risk patients for CD, such as those with autoimmune diseases, is a reasonable strategy given the increased prevalence. Treatment of CD with a gluten-free diet should reduce the recognized complications of this disease and provide benefits in both general health and perhaps life expectancy. It also improves glycemic control in patients with type 1 diabetes mellitus and enhances the absorption of medications for associated hypothyroidism and osteoporosis. It

    2014-03-01

    To summarize the recent advances in coeliac disease. Details of the polygenic nature of coeliac disease with the human leukocyte antigen (HLA) locus as the dominating genetic element have been uncovered. The existence of a large number of non-HLA coeliac disease genes, only partly shared by each individual patient, suggests the genetic heterogeneity of the disease. The critical role for HLA-DQ-restricted CD4 T cells recognizing antigenic gluten peptides is further substantiated. Involvement of CD8 T cells has received new attention. Other components of wheat than gluten, in particular the amylase trypsin inhibitors, may also play a role. The disease is becoming more prevalent. New guidelines state that coeliac disease diagnosis in children can be made on the basis of clinical signs, serology and genetics without the need of biopsy. The clinical entity 'noncoeliac gluten sensitivity' has received much attention, but diagnostic and pathophysiological definitions are still elusive. The risk for mortality and morbidity in coeliac disease is less than previously thought. Our understanding of the basic and clinical aspects of coeliac disease increases. Coeliac disease stands out as a major health problem of almost global occurrence. Case finding, distinguishing coeliac disease from other gluten-sensitive conditions, better care and balanced use of resources are the current challenges.

  4. Genetics of Proteasome Diseases

    Aldrin V. Gomes

    2013-01-01

    Full Text Available The proteasome is a large, multiple subunit complex that is capable of degrading most intracellular proteins. Polymorphisms in proteasome subunits are associated with cardiovascular diseases, diabetes, neurological diseases, and cancer. One polymorphism in the proteasome gene PSMA6 (−8C/G is associated with three different diseases: type 2 diabetes, myocardial infarction, and coronary artery disease. One type of proteasome, the immunoproteasome, which contains inducible catalytic subunits, is adapted to generate peptides for antigen presentation. It has recently been shown that mutations and polymorphisms in the immunoproteasome catalytic subunit PSMB8 are associated with several inflammatory and autoinflammatory diseases including Nakajo-Nishimura syndrome, CANDLE syndrome, and intestinal M. tuberculosis infection. This comprehensive review describes the disease-related polymorphisms in proteasome genes associated with human diseases and the physiological modulation of proteasome function by these polymorphisms. Given the large number of subunits and the central importance of the proteasome in human physiology as well as the fast pace of detection of proteasome polymorphisms associated with human diseases, it is likely that other polymorphisms in proteasome genes associated with diseases will be detected in the near future. While disease-associated polymorphisms are now readily discovered, the challenge will be to use this genetic information for clinical benefit.

    2015-12-01

    Full Text Available Multiple cystic lung disease represents a diverse group of uncommon disorders that can present a diagnostic challenge due to the increasing number of diseases associated with this presentation. High-resolution computed tomography of the chest helps to define the morphological aspects and distribution of lung cysts, as well as associated findings. The combination of appearance upon imaging and clinical features, together with extrapulmonary manifestations, when present, permits confident and accurate diagnosis of the majority of these diseases without recourse to open-lung biopsy. The main diseases in this group that are discussed in this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and folliculin gene-associated syndrome (Birt–Hogg–Dubé; other rare causes of cystic lung disease, including cystic metastasis of sarcoma, are also discussed. Disease progression is unpredictable, and understanding of the complications of cystic lung disease and their appearance during evolution of the disease are essential for management. Correlation of disease evolution and clinical context with chest imaging findings provides important clues for defining the underlying nature of cystic lung disease, and guides diagnostic evaluation and management.

  6. Coeliac disease and epilepsy.

    LENUS (Irish Health Repository)

    Cronin, C C

    2012-02-03

    Whether there is an association between coeliac disease and epilepsy is uncertain. Recently, a syndrome of coeliac disease, occipital lobe epilepsy and cerebral calcification has been described, mostly in Italy. We measured the prevalence of coeliac disease in patients attending a seizure clinic, and investigated whether cerebral calcification occurred in patients with both coeliac disease and epilepsy. Screening for coeliac disease was by IgA endomysial antibody, measured by indirect immunofluorescence using sections of human umbilical cord. Of 177 patients screened, four patients were positive. All had small-bowel histology typical of coeliac disease. The overall frequency of coeliac disease in this mixed patient sample was 1 in 44. In a control group of 488 pregnant patients, two serum samples were positive (1 in 244). Sixteen patients with both coeliac disease and epilepsy, who had previously attended this hospital, were identified. No patient had cerebral calcification on CT scanning. Coeliac disease appears to occur with increased frequency in patients with epilepsy, and a high index of suspicion should be maintained. Cerebral calcification is not a feature of our patients with epilepsy and coeliac disease, and may be an ethnically-or geographically-restricted finding.

    More than a century of research has shown that atherosclerosis is an inflammatory process more than an infiltrative or thrombogenic process. It has been demonstrated epidemiologically and by imaging techniques, that systemic inflammatory diseases (in particular, but not exclusively, rheumatoid arthritis and systemic lupus erythematosus) increase the atherosclerotic process, and has a demonstrated pathophysiological basis. Furthermore, treatments to control inflammatory diseases can modify the course of the atherosclerotic process. Although there are no specific scales for assessing cardiovascular risk in patients with these diseases, cardiovascular risk is high. A number of specific risk scales are being developed, that take into account specific factors such as the degree of inflammatory activity. Copyright © 2015 Sociedad Española de Arteriosclerosis.

Această patologie ridică mari probleme la nivel global din cauza mortalității ridicate (care în anumite situații atinge 30% precum și din cauza încarcăturii financiare mari. Sepsisul se caracterizează prin declasnșarea unor căi imune pro-inflamatorii cu rol de apărare a organismului dar care ulterior se dovedesc a fi extrem de dezajantajoase. Deși antibioterapia, resuscitarea volemică, terapia vasopresoare și controlul sursei de infecție rămân strategiile recomandate în tratamentul sepsisului, date publicate recent propun statinele ca o noua linie de tratament. Aceste medicamente au fost introduse în practica clinică datorită efectului hipocolesterolemiant însă inhibarea reductazei HMG-CoA și a biosintezei colesterolului induce o serie de efecte mai puțin studiate denumite generic pleiotrope: anti-inflamatoare, antitrombotice, imunomodulatoare și antioxidante. Obiective: În cadrul acestui experiment ne-am propus să evaluăm și să comparăm efectul antiinflamator al Simvastatinei și Rosuvastatinei măsurând nevelele serice ale IL-1β, IL-6 și TNF-α folosind un model consacrat de sepsis la șobolan. Metode: Am alcătuit patru grupuri (C, n=7; SEP, SV, RV, n=8. Statinele au fost administrate în două doze cu 18 și 3 ore înaintea intervenției chirurgicale. Sepsisul a fost obținut prin tehnica ligaturării și puncției cecale. De la fiecare subiect au fost recoltate eșantioane de sânge prin puncție venoasă în zilele 1, 4, 7 și 14 (ultimele eșantioane au fost obținute prin puncție cardiacă. Au fost analizați următorii parametrii: hemoleucograma, Procalcitonina, IL-1β, IL-6 și TNF-α. Rezultate: Numărul total al leucocitelor a fost mai mare pentru grupul septic dar netratat.

    This article presents the actual classification of neuromuscular diseases based on present expansion of our knowledge and understanding due to genetic developments. It summarizes the genetic and clinical presentations of each disorder together with CT findings, which we studied in a large group of patients with neuromuscular diseases. The muscular dystrophies as the largest and most common group of hereditary muscle diseases will be highlighted by giving detailed information about the role of CT and MRI in the differential diagnosis. The radiological features of neuromuscular diseases are atrophy, hypertrophy, pseudohypertrophy and fatty infiltration of muscles on a selective basis. Although the patterns and distribution of involvement are characteristic in some of the diseases, the definition of the type of disease based on CT scan only is not always possible.

  10. Liver disease in menopause.

    Science.gov (United States)

    Brady, Carla W

    2015-07-07

    There are numerous physiologic and biochemical changes in menopause that can affect the function of the liver and mediate the development of liver disease. Menopause represents a state of growing estrogen deficiency, and this loss of estrogen in the setting of physiologic aging increases the likelihood of mitochondrial dysfunction, cellular senescence, declining immune responses to injury, and disarray in the balance between antioxidant formation and oxidative stress. The sum effect of these changes can contribute to increased susceptibility to development of significant liver pathology, particularly nonalcoholic fatty liver disease and hepatocellular carcinoma, as well as accelerated progression of fibrosis in liver diseases, as has been particularly demonstrated in hepatitis C virus liver disease. Recognition of the unique nature of these mediating factors should raise suspicion for liver disease in perimenopausal and menopausal women and offer an opportunity for implementation of aggressive treatment measures so as to avoid progression of liver disease to cirrhosis, liver cancer and liver failure.

    This article presents the actual classification of neuromuscular diseases based on present expansion of our knowledge and understanding due to genetic developments. It summarizes the genetic and clinical presentations of each disorder together with CT findings, which we studied in a large group of patients with neuromuscular diseases. The muscular dystrophies as the largest and most common group of hereditary muscle diseases will be highlighted by giving detailed information about the role of CT and MRI in the differential diagnosis. The radiological features of neuromuscular diseases are atrophy, hypertrophy, pseudohypertrophy and fatty infiltration of muscles on a selective basis. Although the patterns and distribution of involvement are characteristic in some of the diseases, the definition of the type of disease based on CT scan only is not always possible

  12. GAUCHER’S DISEASE

    Full Text Available The article gives data on epidemiology, pathogenesis, modern classification and the main clinical manifestations of Gaucher’s disease in children; it also gives criteria of differential diagnostics with other diseases. The article shows that the only effective method of treating Gaucher’s disease is pathogenic enzyme-substitutive therapy which arrests the main clinical manifestations of the disease improving life quality of patients without pronounced side effects. Imiglucerase is used for such treatment; it causes hydrolysis of glucocerebroside into glucose and ceramide (regular metabolism of membrane lipids. Imiglucerase is indicated for long-term enzyme-substitutive therapy in patients with confirmed Gaucher’s disease (types 1 and 3. It is recommended to monitor condition of patients in the setting of therapy in compliance with the requirements of the International Collaborative Gaucher Group. The article cites the main mistakes of diagnostics and management of such patients and ungrounded prescriptions when treating this disease.

    Interstitial lung diseases comprise a heterogeneous group of about 200 entities. In the classification of these diseases, diffuse parenchymal lung diseases with known cause, granulomatous diseases, and other specific interstitial lung diseases are separated from the important group of idiopathic interstitial pneumonias, which are classified according to the 2002 ATS/ERS consensus classification. Concerning the histological pattern, this classification differentiates between "usual interstitial pneumonia" (UIP), "nonspecific interstitial pneumonia" (NSIP), "organising pneumonia" (COP), "diffuse alveolar damage" (DAD), "respiratory bronchiolitis" (RB), "desquamative interstitial pneumonia" (DIP), "lymphocytic interstitial pneumonia" (LIP) and "unclassifiable interstitial pneumonias". A key message of this classification is that the pathologist will give the diagnosis of a histological pattern, whereas the final clinicopathologic diagnosis can be made only by the clinical pulmonologist after careful correlation with the clinical and radiologic features, which is essential in the diagnosis of interstitial lung diseases.

    Periodontal disease is considered to be an opportunistic infection as a result of interactions between the causative agents (dental plaque) and the host responses which may be modulated by genetic, environmental and acquired risk factors. Besides being a well-confirmed risk factor in a number of systemic diseases, tobacco smoking has also been associated with periodontal disease. Over the past 10-15 years, more and more scientific data on the impact of smoking on various aspects of periodontal disease and the underlying mechanisms has been published. The purpose of this review was to provide an overview of the available data in order to give practitioners a better understanding of the relationship between smoking and periodontal disease. Subsequently, they can use some of the information in treatment decisions and give advice to patients who are smokers suffering from periodontal disease.

    The article describes the previously proposed technical methods of operation for the inflammatory infiltration of the blind gut cupola resulting from destructive appendicitis. Their disadvantages are shown. The authors propose to cover the blind gut cupola with parietal peritoneum and fix it to the gut with sutures, if the infiltration of the blind gut cupola is considerable and it is impossible to dip the process stump by a purse-string and Z-shaped suture.

    Full Text Available Introduction. Intussusception is a rare clinical entity in adults (<1% of intestinal obstructions. Colonic intussusception is even rarer, particularly when caused by lipomas. Case Presentation. A 47-year-old woman presented to our emergency department complaining of abdominal pain with vomiting and diarrhoea. X-ray and CT showed bowel obstruction due to ileocolonic and colocolonic intussusception; a giant colonic lipoma (9 × 4 × 4 cm was recognizable immediately distally to the splenic flexure of the colon. The patient underwent emergency laparotomy and right hemicolectomy. Assessment of the resected specimen confirmed the diagnosis of giant colonic polypoid lesion near to the ileocecal valve, causing a 12 cm long intussusception with moderate ischemic damage. Conclusion. Colonic obstruction due to intussusception caused by lipomas is a very rare condition that needs urgent treatment. CT is the radiologic modality of choice for diagnosis (sensitivity 80%, specificity near 100%; since the majority of colonic intussusceptions are caused by primary adenocarcinoma, if the etiology is uncertain, the lesion must be interpreted as malignant and extensive resection is recommended. At present, surgery is the treatment of choice and determines an excellent outcome.

    Full Text Available Hiroyuki Miyatani1, Yukio Yoshida1, Hirokazu Kiyozaki21Department of Gastroenterology, Jichi Medical University, Saitama Medical Center, Saitama, Japan; 2Department of Surgery, Jichi Medical University, Saitama Medical Center, Saitama, JapanAbstract: Colonic perforation caused by upper gastrointestinal (GI endoscopy is extremely rare. A 69-year-old woman was referred to our hospital because of abdominal fullness. Colonoscopy could be performed only up to the hepatic flexure due to an elongated colon and residual stools. Because her symptoms improved, upper GI endoscopy was performed 11 days later. The patient developed severe abdominal pain two hours after the examination. Abdominal X-ray and computed tomography showed massive free air. Immediate laparotomy was performed for the intestinal perforation. After removal of stool, a perforation site was detected in the cecum with an invasive ascending colon cancer. Therefore, a right hemicolectomy, ileostomy, and transverse colostomy were performed. Although she developed postoperative septicemia, the patient was discharged 38 days after admission. Seven months postoperatively, the patient died of lung, liver, and brain metastases. Even in cases with a lesion that is not completely obstructed, it is important to note that air insufflations during upper GI endoscopy can perforate the intestinal wall in patients with advanced colon cancer.Keywords: colonic perforation, colon cancer, upper gastrointestinal endoscopy, fecal peritonitis

    The effect of interaction of crude protein level in the diet and coccidiosis of the cecum and small intestine of chicks was investigated. A total of 390 day-old chicks were divided in 36 groups of ten and six groups of five chicks each. Twelve groups of ten and two groups of six chicks each were fed one of the three diets based on dietary crude protein level (16%, 20% and 24%). All diets contained an equal energy concentration. The chicks were on the appropriate diet for 15 days prior to infection. Each group was then subjected to one of the three treatments (a) control, (b) a single dose infection with 100,000 oocysts of Eimeria acervulina and (c) a single dose infection with 10,000 oocysts of Eimeria tenella. On the eighth day post infection all surviving E. tenella infected chicks and two replicates per dietary treatment of control and E. acervulina infected chicks were killed. An increase in dietary crude protein led to a linear (PCoccidiosis caused a reduction in daily gain, feed consumption and efficiency of feed utilization, the effect being more severe in E. tenella infection. The effect of dietary crude protein was protective against weight reduction. Chicks infected with E. tenella fed 24% crude protein had a higher (P<0.01) mortality rate than those fed on 16% or 20% crude protein level. The oocyst production by E. acervulina infected chicks was also higher (P<0.01) at the 24% crude protein level. The E. acervulina infected chicks exhibited compensatory growth during the eight to 14 days post infection. The compensatory growth was superior at the higher crude protein levels. The mechanism of compensatory growth is discussed. PMID:4266700

    In ruminants, gastrointestinal recycling of urea is acutely enhanced by fibre-rich diets that lead to high ruminal concentration of short chain fatty acids (SCFA), while high ammonia has inhibitory effects. This study attempted to clarify if urea flux to the porcine cecum is similarly regulated.

    Marburg virus disease, Lassa fever, monkeypox, and Ebola virus diseases of humans have all been recognized since 1967. These are examples of some of the exotic virus diseases which through importation may present a potential public health problem in the United States. Some of these viruses are also highly hazardous to laboratory and medical personnel. This paper is a review of the general characteristics, the epidemiology, and laboratory diagnosis of the exotic viruses which have been described during the last 25 years.

    Although many people these days actually work very hard at leisure time activities, diseases are most commonly acquired from birds during the course of work in the usual sense of the term, not leisure. However, travel for pleasure to areas where the diseases are highly endemic puts people at risk of acquiring some of these bird-related diseases (for example, histoplasmosis and arbovirus infections), as does ownership of birds as pets (psittacosis).

    An increasing number of diseases are recognized as being sexually transmitted. The majority of these are bacterial or viral in nature; however, several protozoan and nematode infections can also be transmitted by sexual activity. For most of these diseases, the primary mode of transmission is nonsexual in nature, but sexual activity that results in fecal-oral contact can lead to transmission of these agents. Two parasitic diseases commonly transmitted by sexual contact are amebiasis and giard...

    Moyamoya disease is a progressive vasculopathy leading to stenosis of the main intracranial arteries. The incidence of moyamoya disease is high in Asian countries; in Europe and North America, the prevalence of the disease is considerably lower. Clinically, the disease may be of ischaemic, haemorrhagic and epileptic type. Cognitive dysfunction and behavioral disturbance are atypical symptoms of moyamoya disease. Characteristic angiographic features of the disease include stenosis or occlusion of the arteries of the circle of Willis, as well as the development of collateral vasculature. Currently, magnetic resonance angiography and CT angiography with multi-row systems are the main imaging methods of diagnostics of the entire range of vascular changes in moyamoya disease. The most common surgical treatment combines the direct arterial anastomosis between the superficial temporal artery and middle cerebral, and the indirect synangiosis involving placement of vascularised tissue in the brain cortex, in order to promote neoangiogenesis. Due to progressive changes, correct and early diagnosis is of basic significance in selecting patients for surgery, which is the only effective treatment of the disease. An appropriate qualification to surgery should be based on a comprehensive angiographic and imaging evaluation of brain structures. Despite the rare occurrence of moyamoya disease in European population, it should be considered as one of causes of ischaemic or haemorrhagic strokes, especially in young patients

  18. Immunologic lung disease

    Harman, E.M.

    1985-01-01

    The term immunologic lung disease comprises a broad spectrum of disease. The authors have covered a few entities in which recent studies have been particularly helpful in elucidating pathophysiology though not in uncovering the inciting cause. Common to all of these entities is the problem of finding appropriate methods of defining disease activity and response to treatment. As exemplified by the improved outlook for Goodpasture's syndrome with elucidation of its underlying immunopathology, it is likely that better understanding of the immunologic basis of sarcoid and interstitial disease may be helpful in planning more effective treatment strategies. 44 references
