    Diarrhea can result from damage to the intestinal lining caused by viruses or bacteria, malabsorption, inflammatory processes, bile salt and pancreatic enzyme deficiency, abnormal motility, or the presence of osmotically active solutes in the gut. While it is important to elicit information to determine the possible cause of diarrhea, be sure to check circulatory status first. Some patients may need rehydration therapy more urgently than they need a diagnosis. The main goals of treatment are to prevent dehydration and correct electrolyte imbalance, to provide supportive and symptomatic therapy, and to treat underlying disease. In most cases, a specific diagnosis is not necessary to guide initial treatment.

    Chronic, non-infectious diarrhea can be caused by a variety of gastrointestinal diseases. In anamnesis, it is important to take accompanying warning symptoms and specific triggers into account. The fecal inflammatory marker calprotectin may help differentiating between organic and functional gastrointestinal disorders, but it is not specific. Among other options, gelling fibres, Loperamide and Cholestyramine as well as probiotics are available for the symptomatic treatment of chronic diarrhea. For long-term treatment of chronic diarrhea with the enkephalinase inhibitor racecadotril, which is approved for acute diarrhea, only limited data are available. Eluxadolin presents a new therapeutic option. It can alleviate abdominal pain and diarrhea by modulation of opioid receptors in the enteric nervous system. Additional approaches in intractable irritable bowel syndrome with diarrhea (IBS-D) include 5-HT3 receptor antagonists, the antibiotic Rifaximin as well as low-dose tricyclic antidepressants. Specific diets such as the low-FODMAP diet can also relieve symptoms in IBS. PMID:27642742

  4. Probiotics for Infectious Diarrhea and Traveler's Diarrhea - What Do We Really Know?

    Hibberd, Patricia L.

    Worldwide, diarrhea is the sixth leading cause of premature death (Lopez et al., 2006), accounting for more than two million deaths each year. The majority of the burden is borne in lower and middle income countries, and in children under age 5 (Kosek et al., 2003). Even in the United States where there is easy access to “safe” food and water, there are an estimated 211-375 million episodes of acute diarrhea each year, resulting in 900,000 hospitalizations and 6,000 deaths (Herikstad et al., 2002; Mead et al., 1999). While mortality from diarrhea has decreased over the last 30 years, the incidence and morbidity associated with diarrhea has not improved (Kosek et al., 2003). During the same time period an ever increasing number of enteric pathogens as well as non-infectious conditions have been recognized as causes of acute diarrhea (Guerrant et al., 2001).

    Full Text Available Acute diarrhea (AD is the most frequent gastroenterological disorder, and the main cause of dehydration in childhood. It is manifested by a sudden occurrence of three or more watery or loose stools per day lasting for seven to 10 days, 14 days at most. It mainly occurs in children until five years of age and particularly in neonates in the second half-year and children until the age of three years. Its primary causes are gastrointestinal infections, viral and bacterial, and more rarely alimentary intoxications and other factors. As dehydration and negative nutritive balance are the main complications of AD, it is clear that the compensation of lost body fluids and adequate diet form the basis of the child’s treatment. Other therapeutic measures, except antipyretics in high febrility, antiparasitic drugs for intestinal lambliasis, anti-amebiasis and probiotics are rarely necessary. This primarily regards uncritical use of antibiotics and intestinal antiseptics in the therapy of bacterial diarrhea. The use of antiemetics, antidiarrhetics and spasmolytics is unnecessary and potentially risky, so that it is not recommended for children with AD.

    Infectious diarrhea is very common; its severity ranges from uncomplicated, self-limiting courses to potentially life-threatening disease. A rapid diagnostic workup providing detailed information on the suspected pathogen should be performed only in patients at risk, analyzing one single stool sample for Salmonella, Shigella, Campylobacter, and Norovirus. In the presence of risk factors, such as a history of antibiotic exposure within the last 3 months, testing for Clostridium difficile should be performed. Immunocompetent patients do not require specific antibiotic therapy. Exceptions exist in patients with severe comorbidities, immunodeficiency, fever/SIRS, and in patients with Shigella or C. difficile infection. Empirical antibiotic treatment should be considered in patients with fever and/or bloody diarrhea and in patients at risk. In patients with traveler's diarrhea, microbiological diagnosis is required only in patients with fever, bloody diarrhea, prolonged course of disease (more than 5 days), severe clinical course with hypotension or dehydration, and during outbreaks. In these patients one single fecal sample should be collected for stool cultures of Campylobacter, Shigella, and Salmonella, as well as microscopic examination for amoebiasis and Giardiasis. The main therapeutic measure for infectious diarrhea is sufficient oral rehydration. As in community-acquired diarrhea, azithromycin or ciprofloxacin are recommended-taking into account local antimicrobial resistance in the country of travel and possible side effects. PMID:26573083

    Norovirus infection usually results in acute gastroenteritis, often with incapacitating nausea, vomiting, and diarrhea. It is highly contagious and resistant to eradication with alcohol-based hand sanitizer. Appropriate preventative and infection control measures can mitigate the morbidity and mortality associated with norovirus infection. Clostridium difficile infection is the leading cause of health care-associated diarrhea in the United States. Antibiotic use is by far the most common risk factor for C difficile colonization and infection. Appropriate preventive measures and judicious use of antibiotics can help mitigate the morbidity and mortality associated with C difficile infection. PMID:27394020

    Full Text Available Background Diarrhea is one of the major causes of morbidity and mortality in children throughout the world, mostly due to rotavirus infection. In daily practice, we routinely use the World Health Organization Five steps for managing acute diarrhea.This practice has shown great success in diarrhea management, but concerns remain on reducing the duration of diarrhea to prevent complications. Synbiotics can reduce the severity of diarrhea. However, there has been limited data on synbiotic therapy for treating acute rotavirus diarrhea in children. Objective To compare the durations of acute rotavirus diarrhea treated with synbiotics vs. placebo. Methods This study was a randomized, double-blind, clinical trial, performed at the Pediatric Gastrohepatology Division, Sanglah and Wangaya Hospitals in Denpasar. Subjects were children aged 6 to 59 months with acute rotavirus diarrhea. Rotavirus was diagnosed by immune chromatography assay. The synbiotic group received probiotic comprised of Lactobacillus sp., Streptococcus sp., Bifidobacterium sp. (total viable count 1.00x109 CFU per dose, and prebiotic consisted of 990.00 mg fructooligosacharide (FOS. The placebo consisted of lactose monohydrate packaged similarly as the synbiotics. Subjects orally ingested 1 pack per day for 5 days. Results Seventy children with acute rotavirus diarrhea was involved in this study. The median duration of diarrhea in the synbiotic group was 50.0 (SE 1.1; 95%CI 47.9 to 52.1 hours, while that of the placebo group was 63.0 (SE 5.9; 95%CI 51.4 to 74.6 hours. Based on Kaplan-Meier survival analysis, the duration of diarrhea in the synbiotic group was significantly shorter than that of the placebo group (log-rank test P <0.0001. Conclusion In children with acute rotaviral diarrhea, synbiotic reduces the duration of diarrhea compared to placebo. [Paediatr Indones. 2015;55:74-8.].

    Diarrhea is common in the acute care setting, particularly among critically ill patients. Factors that cause diarrhea are usually multifactorial; some of the most common include medications, hyperosmolar or rapidly delivered tube feedings, atrophy of intestinal epithelium or ischemic bowel, short bowel syndrome, pseudomembranous colitis, infection (Salmonella and Shigella species), opportunistic infections in patients with acquired immunodeficiency syndrome and severe hypoproteinemia. This article reviews different types and mechanisms of diarrhea commonly encountered in acute care. It includes current concepts of managing diarrhea, such as calculation of stool osmotic gap, identification of medications that cause diarrhea, modification of enteral therapy, and the use of antisecretory agents. Nursing responsibilities and contributions in the collaborative assessment and clinical management of diarrhea are also explored. PMID:7704125

    Full Text Available Infectious diarrhea, a common disease of children, deserves permanent monitoring in all social groups. To know the etiology and clinical manifestations of acute diarrhea in children up to 5 years of age from high socioeconomic level households, we conducted a descriptive, microbiological, and clinical study. Stools from 59 children with acute community-acquired diarrhea were examined, and their parents were interviewed concerning symptoms and signs. Rotavirus, adenovirus, and norovirus were detected by commercially available qualitative immunochromatographic lateral flow rapid tests. Salmonella, Campylobacter, Yersinia, and Shigella were investigated by standard bacteriological methods and diarrheagenic E. coli by PCR assays. We identified a potential enteric pathogen in 30 children. The most frequent causes of diarrhea were enteropathogenic E. coli (EPEC, viruses, Campylobacter, Salmonella, and Shiga-toxin-producing E. coli (STEC. Only 2 patients showed mixed infections. Our data suggest that children with viral or Campylobacter diarrhea were taken to the hospital earlier than those infected with EPEC. One child infected with STEC O26 developed “complete” HUS. The microbiological results highlight the importance of zoonotic bacteria such as atypical EPEC, Campylobacter, STEC, and Salmonella as pathogens associated with acute diarrhea in these children. The findings also reinforce our previous communications about the regional importance of non-O157 STEC strains in severe infant food-borne diseases.

    AIM: During emergency period, infectious diseases can bea major threat to military forces. During field training insouthern China, diarrhea is the main cause of nonbattleinjury. To evaluate the causes of and risk factors for diarrheain emergency period, we collected clinical and epidemiologicaldata from the People′s Liberation Army (PLA) during fieldtraining in southern China.METHODS: From September 25 to October 2 1997, 2636military personnel were investigated. Fecal sample cultures for lapactic pathogens were obtained from 103 military personnel with diarrhea. In addition, a questionnaire was administered to 103 cases and 206 controls to evaluate the association between illness and potential risk factors. At the same time,another questionnaire of 1:4 case-case control was administered to 22 severe cases (each severe case paired 4 mild cases).RESULTS: The training troop′s diarrhea incidence rate was significantly higher than that of garrison. The diarrhea incidence rate of officers was significantly lower than that of soldiers. A lapactic pathogen was identified in 63.1% (65/103) of the troops with diarrhea. Enterotoxigenic Escherichia coli(35.0%) and plesiomona shigelloides (16.5%) were the most common bacterial pathogens. All bacterial isolates were sensitive to norfloxacin and ceftazidine. However, almost all of them were resistant to sulfamethoxazole, trimethoprim-sulfamethoxazole,oxytetracycline, doxycycline, furazolidone, ampicillin and cloromycetin to a different degree. Risk factors associated with diarrhea includediidrinking raw water, eating outside,contacting diarrhea patients, lacking sanitation, depression,lacking sleep, which were established by multiple-factor logistic regression analysis. In addition, the unit incidence rate was associated with the density of flies and the average daily boiled water available by regression and discriminate analysis.CONCLUSION: A series of risk factors are associated with the incidence rate of diarrhea.

    Full Text Available BACKGROUND: Persistent and heavy rainfall in the upper and middle Huaihe River of China brought about severe floods during the end of June and July 2007. However, there has been no assessment on the association between the floods and infectious diarrhea. This study aimed to quantify the impact of the floods in 2007 on the burden of disease due to infectious diarrhea in northwest of Anhui Province. METHODS: A time-stratified case-crossover analysis was firstly conducted to examine the relationship between daily cases of infectious diarrhea and the 2007 floods in Fuyang and Bozhou of Anhui Province. Odds ratios (ORs of the flood risk were quantified by conditional logistic regression. The years lived with disability (YLDs of infectious diarrhea attributable to floods were then estimated based on the WHO framework of the calculating potential impact fraction in the Burden of Disease study. RESULTS: A total of 197 infectious diarrheas were notified during the exposure and control periods in the two study areas. The strongest effect was shown with a 2-day lag in Fuyang and a 5-day lag in Bozhou. Multivariable analysis showed that floods were significantly associated with an increased risk of the number cases of infectious diarrhea (OR = 3.175, 95%CI: 1.126-8.954 in Fuyang; OR = 6.754, 95%CI: 1.954-23.344 in Bozhou. Attributable YLD per 1000 of infectious diarrhea resulting from the floods was 0.0081 in Fuyang and 0.0209 in Bozhou. CONCLUSIONS: Our findings confirm that floods have significantly increased the risks of infectious diarrhea in the study areas. In addition, prolonged moderate flood may cause more burdens of infectious diarrheas than severe flood with a shorter duration. More attention should be paid to particular vulnerable groups, including younger children and elderly, in developing public health preparation and intervention programs. Findings have significant implications for developing strategies to prevent and reduce health

    Full Text Available Guangdong province is one of the most vulnerable provinces to tropical cyclones in China. Most prior studies concentrated on the relationship between tropical cyclones and injuries and mortality. This study aimed to explore the impacts of different grades of tropical cyclones on infectious diarrhea incidence in Guangdong province, from 2005 to 2011.Mann-Whitney U test was firstly used to examine if infectious diarrhea were sensitive to tropical cyclone. Then unidirectional 1:1 case-crossover design was performed to quantitatively evaluate the relationship between daily number of infectious diarrhea and tropical cyclone from 2005 to 2011 in Guangdong, China. Principal component analysis (PCA was applied to eliminate multicollinearity. Multivariate logistic regression model was used to estimate the hazard ratios (HRs and the 95% confidence intervals (CI.There were no significant relationships between tropical cyclone and bacillary dysentery, amebic dysentery, typhoid, and paratyphoid cases. Infectious diarrhea other than cholera, dysentery, typhoid and paratyphoid significantly increased after tropical cyclones. The strongest effect were shown on lag 1 day (HRs = 1.95, 95%CI = 1.22, 3.12 and no lagged effect was detected for tropical depression, tropical storm, severe tropical storm and typhoon, with the largest HRs (95%CI of 2.16 (95%CI = 1.69, 2.76, 2.43 (95%CI = 1.65, 3.58 and 2.21 (95%CI = 1.65, 2.69, respectively. Among children below 5 years old, the impacts of all grades of tropical cyclones were strongest at lag 0 day. And HRs were 2.67 (95%CI = 1.10, 6.48, 2.49 (95%CI = 1.80, 3.44, 4.89 (95%CI = 2.37, 7.37 and 3.18 (95%CI = 2.10, 4.81, respectively.All grades of tropical cyclones could increase risk of other infectious diarrhea. Severe tropical storm has the strongest influence on other infectious diarrhea. The impacts of tropical cyclones on children under 5 years old were higher than total population.

    Full Text Available Objectives. Physiologic and immunologic changes in pregnancy result in increased susceptibility to infection. These shifts are more pronounced in pregnancies complicated by multiple gestation. The objective of this study was to determine the association between multiple gestation and risk of infectious morbidity. Study Design. The Nationwide Inpatient Sample for the years 2008–2010 was used to identify pregnant women during admission for delivery with International Classification of Diseases codes. Logistic regression was used to compute odds ratios and 95% confidence intervals for demographic data, preexisting medical conditions, and acute medical and infectious complications for women with multiple versus singleton gestations. Results. Among women with multiple gestation, 38.4 per 1,000 women had an infectious complication compared to 12.8 per 1,000 women with singletons. The most significant infectious morbidity associated with multiple gestation was intestinal infections, pyelonephritis, influenza, and pneumonia. After controlling for confounding variables, infectious complications at delivery persisted for women with multiples, though the association was dependent on mode of delivery. Conclusions. Women with multiple gestations are at increased risk for infectious morbidity identified at the time of delivery. This association was diminished among women who had a cesarean suggesting that operative delivery is not responsible for this association.

    Full Text Available Economic performance of beef cattle operations can be severely hampered by acute calfhood diarrhea. Accordingly, a study was conducted at Bbalitvet to identify the causal agents, reduce clinical incidence, and increase body weight gain of newborn calves. One potential control is application of suitable vaccines to pregnant cows. The study was begun by identifying cases of diarrhea followed by isolation and identification of the causal agents in 12 beef cattle farms in West Java. A field trial was then designed for controlling calf diarrhea in such farms. Inactive vaccines Ecoli-Closvak polivalen were administered to pregnant cows to increase specific resistance of the newborn calves. At 2 months prepartum, 12 pregnant cows were assigned either to a vaccination or a placebo group, with a booster vaccination 3 weeks prior to parturition. Strict hygenic management was provided to both groups, and all calves were provided adequately with colostrum. Subjects were observed for 5 months, starting from the time of initial vaccination until the calves were 3 months of age. In the initial farm surveys, entero-pathogenic bacteria such as Escherichia coli serotype K99 and Clostridium perfringens type A and C were isolated and identified in fecal samples from 4 beef cattle farms in 3 districts (Garut, Tasikmalaya, Ciamis and 2 beef cattle farms in 2 districts (Tasikmalaya and Ciamis of West Java. In the vaccination trial, good immune responses to E. coli and C. perfringens alpha toxin measured by ELISA were observed. Application of effective control of calf diarrhea including vaccination and good livestock management showed good results. No death or signs of diarrhea were found in the new born calves up to 3 months of age. The rate of body weight gain was significantly higher in calves of vaccinated dams than in calves of non-vaccinated dams.

    Shaun K Morris

    Full Text Available BACKGROUND: Little is known about the causes of death in children in India after age five years. The objective of this study is to provide the first ever direct national and sub-national estimates of infectious disease mortality in Indian children aged 5 to 14 years. METHODS: A verbal autopsy based assessment of 3 855 deaths is children aged 5 to 14 years from a nationally representative survey of deaths occurring in 2001-03 in 1.1 million homes in India. RESULTS: Infectious diseases accounted for 58% of all deaths among children aged 5 to 14 years. About 18% of deaths were due to diarrheal diseases, 10% due to pneumonia, 8% due to central nervous system infections, 4% due to measles, and 12% due to other infectious diseases. Nationally, in 2005 about 59 000 and 34 000 children aged 5 to 14 years died from diarrheal diseases and pneumonia, corresponding to mortality of 24.1 and 13.9 per 100 000 respectively. Mortality was nearly 50% higher in girls than in boys for both diarrheal diseases and pneumonia. CONCLUSIONS: Approximately 60% of all deaths in this age group are due to infectious diseases and nearly half of these deaths are due to diarrheal diseases and pneumonia. Mortality in this age group from infectious diseases, and diarrhea in particular, is much higher than previously estimated.

    Full Text Available In China, great differences in economy, social characteristics and hygiene exist between developing and developed regions. A comparative study of infectious diarrhea between two regions was needed. Three groups of diarrheal patients were collected: children ≤5 year-olds from Beijing (developed region and Henan Province (developing region, and adults over 18 year-olds from Beijing. A questionnaire was used to survey and feces samples were examined for 16 enteropathogens. We enrolled 1422 children and 1047 adults from developed region and 755 children from developing region. Virus positive rates were 32.98% for children and 23.67% for adults in developed region. The most prevalent pathogen for children was rotavirus whereas for adults was norovirus. Bacterial isolation rates were 13.92% for children from developed region, while 29.14% for children from the developing regions. For the greatest difference, Shigella accounted for 50.79% and was the dominant pathogen in the developing region, whereas in the developed region it was only 1.45%. There was no significant relationship between the local levels of development with diarrheogenic Escherichia coli (DEC categories. But it was seen the notable differences between the population with different age: enteropathogenic E.coli (EPEC and enteroaggregative E.coli (EAggEC were the primary classes of DEC in children from both regions, whereas it was enterotoxigenic E.coli (ETEC in adults. The symptoms of Shigella and Salmonella infection, such as bloody stools, white blood cells (WBC and red blood cells (RBC positivity and fever were similar in children, which may lead to the misidentification. Yersinia enterocolitica and shiga toxin-producing E.coli (STEC infections were firstly reported in Beijing. There was a large difference in etiology of bacterial diarrhea between children in developing and developed regions of China.

    Full Text Available Background: Zhejiang Province, located in southeastern China, is frequently hit by tropical cyclones. This study quantified the associations between infectious diarrhea and the seven tropical cyclones that landed in Zhejiang from 2005–2011 to assess the impacts of the accompanying precipitation on the studied diseases. Method: A unidirectional case-crossover study design was used to evaluate the impacts of tropical storms and typhoons on infectious diarrhea. Principal component analysis (PCA was applied to eliminate multicollinearity. A multivariate logistic regression model was used to estimate the odds ratios (ORs and the 95% confidence intervals (CIs. Results: For all typhoons studied, the greatest impacts on bacillary dysentery and other infectious diarrhea were identified on lag 6 days (OR = 2.30, 95% CI: 1.81–2.93 and lag 5 days (OR = 3.56, 95% CI: 2.98–4.25, respectively. For all tropical storms, impacts on these diseases were highest on lag 2 days (OR = 2.47, 95% CI: 1.41–4.33 and lag 6 days (OR = 2.46, 95% CI: 1.69–3.56, respectively. The tropical cyclone precipitation was a risk factor for both bacillary dysentery and other infectious diarrhea when daily precipitation reached 25 mm and 50 mm with the largest OR = 3.25 (95% CI: 1.45–7.27 and OR = 3.05 (95% CI: 2.20–4.23, respectively. Conclusions: Both typhoons and tropical storms could contribute to an increase in risk of bacillary dysentery and other infectious diarrhea in Zhejiang. Tropical cyclone precipitation may also be a risk factor for these diseases when it reaches or is above 25 mm and 50 mm, respectively. Public health preventive and intervention measures should consider the adverse health impacts from tropical cyclones.

    Full Text Available Limited information is available regarding the metabolic consequences of intestinal dysbiosis in dogs with acute onset of diarrhea. The aim of this study was to evaluate the fecal microbiome, fecal concentrations of short-chain fatty acids (SCFAs, as well as serum and urine metabolites in healthy dogs (n=13 and dogs with acute diarrhea (n=13. The fecal microbiome, SCFAs, and serum/urine metabolite profiles were characterized by 454-pyrosequencing of the 16S rRNA genes, GC/MS, and untargeted and targeted metabolomics approach using UPLC/MS and HPLC/MS, respectively. Significantly lower bacterial diversity was observed in dogs with acute diarrhea in regards to species richness, chao1, and Shannon index (p=0.0218, 0.0176, and 0.0033; respectively. Dogs with acute diarrhea had significantly different microbial communities compared to healthy dogs (unweighted Unifrac distances, ANOSIM p=0.0040. While Bacteroidetes, Faecalibacterium, and an unclassified genus within Ruminococcaceae were underrepresented, the genus Clostridium was overrepresented in dogs with acute diarrhea.

    Full Text Available Background In cases of acute diarrhea, it is difficult to distinguish between bacterial and non-bacterial causes. Increased fecal calprotectin (f-CP level is a marker of neutrophil migration in the intestinal lumen and is associated with intestinal inflammation. Previous studies reported an increase in f-CP levels in children with acute diarrhea, which is caused by bacteria, but only few have studied the relationship between intestinal pathogens with f-CP levels in acute diarrhea. Objective To assess for a correlation between gut pathogens and fecal calprotectin levels in children with acute diarrhea. Methods We conducted a cross-sectional study between July to November 2012 on children aged 1-5 years with acute diarrhea, and underwent routine blood tests, stool microscopy, f-CP tests, and stool cultures. We used a simple linear regression and correlation analysis with a significance level of P<0.05. Results Forty-two children enrolled in this study. The mean age of subjects was 2.27 (SD 1.34 years. Their mean f-CP level was 93.88 (SD 14.68 μg/g. On microscopic stool examination, 26 patients (61.9% had positive leukocytes, 1 had Ancylostoma duodenale, 1 had Ascaris lumbricoides, and 2 had Blastocystis hominis. Positive stool cultures were found in 14 children (33.3% with acute diarrhea. There was a significant positive correlation between gut pathogens and f-CP levels (r=0.605; P<0.0001. Conclusion In young children with acute diarrhea, the average f-CP levels are higher in those with positive intestinal pathogens. [Paediatr Indones. 2014;54:193-7.].

    Full Text Available Zinc supplementation is recommended in all acute diarrheas in children from developing countries. We aimed to assess whether zinc supplementation would be equally effective against all the common organisms associated with acute diarrheas. We used data on 801 children with acute diarrhea recruited in a randomized, double blind controlled trial (ISRCTN85071383 of zinc and copper supplementation. Using prespecified subgroup analyses, multidimensionality reduction analyses, tests of heterogeneity, and stepwise logistic regression for tests of interactions, we found that the influence of zinc on the risk of diarrhea for more than 3 days depended on the isolated organism—beneficial in Klebsiella, neutral in Esherichia coli and parasitic infections, and detrimental in rotavirus coinfections. Although we found similar results for the outcome of high stool volume, the results did not reach statistical significance. Our findings suggest that the current strategy of zinc supplementation in all cases of acute diarrheas in children may need appropriate fine tuning to optimize the therapeutic benefit based on the causative organism, but further studies need to confirm and extend our findings.

    Background There has been a marked global increase in the incidence of human Campylobacter enteritis in recent years. This study investigated the epidemiological and clinical features of Campylobacter enteritis in adult patients suffering from acute diarrhea.Methods This was a retrospective review of Campylobacter enteritis in adult patients with acute diarrhea presenting at Beijing University First Hospital, Beijing, China, in the summer and autumn (April to October) of 2005 to 2009. The data collected included the species of campylobacter identified, and the age, gender, clinical manifestations and results of laboratory test on stool samples collected from the patients. Campylobacter sensitivity tests to various antimicrobial agents were conducted on 80 specimens. Chi-square tests were applied using SPSS13.0 software and a two-sided P value of <0.05 was considered statistically significant.Results Campylobacter spp. isolated from the stool specimens of 142 patients with diarrhea represented 14.9% of all the cases examined. C. jejuni was identified in 127 patients (89.4%) and C. coli in 15 others (10.6%). The infection incidence was highest in the age range of 21-30 years which comprised 21.7% of the total cases examined. Most cases of diarrhea (46 patients) occurred in June. Watery diarrhea (97.2%), abdominal pain (72.5%) and fever (64.8%) were the most common manifestations of enteric campylobacteriosis. Only four patients (2.8%) had bloody diarrhea. The antimicrobial resistance rates were: cefoperazone (100%), levofloxacin (61.3%), gentamicin (12.5%), erythromycin (6.3%), and azithromycin (2.5%).Conclusions Campylobacter was prevalent among adults with acute diarrhea from 2005 to 2009 in Beijing, China. The large number of those afflicted by the disease warrants the commission of a large multicenter study to determine the extent of enteric campylobacteriosis in this region.

    Full Text Available Background The incidence rate of acute diarrheal disease in children is a health indicator, and the estimation of these data can help guide public health policies. Objectives The aim of this study was to estimate the incidence and risk factors for acute diarrheal disease in children aged 0 - 1 year. Patients and Methods An observational prospective cohort study was conducted on 210 children recruited at Hospital Nossa Senhora da Conceicao, in Tubarao, state of Santa Catarina, Brazil. Children born between July and September 2012 were followed up for 12 months. The presence of three or more liquid or loose stools during a 24-hour period was considered acute diarrhea. The categories of variables evaluated were comprised of sociodemographic characteristics (per capita income, maternal education, maternal age, access to medical care [public or private], and housing and living conditions [sanitation and hygiene, water supply, daycare attendance, and domestic animal] and characteristics of the child (gender, birth weight, and breastfeeding. Results The incidence of acute diarrhea among the 0 - 1-year-old children was 26.7 cases per 1,000 children per month. Independent risk factors for the occurrence of diarrhea were maternal age under 20 years and health care services provided by the Brazilian National Health System (SUS. Conclusions The high incidence density of diarrhea among the children recruited in this study indicates the need for educational programs directed at people who are involved in this issue.

    Full Text Available OBJECTIVE: To quantify the influence of the type of child-care on the occurrence of acute diarrhea with special emphasis on the effect of children grouping during care. METHODS: From October 1998 to January 1999 292 children, aged 24 to 36 months, recruited using a previously assembled cohort of newborns, were evaluated. Information on the type of care and occurrence of diarrhea in the previous year was obtained from parents by telephone interview. The X² and Kruskal-Wallis tests were used to compare proportions and quantitative variables, respectively. The risk of diarrhea was estimated through the calculation of incident odds ratios (OR and their respective 95% confidence intervals (95% CI, crude and adjusted by unconditional logistic regression. RESULTS: Using as reference category children cared individually at home, the adjusted ORs for diarrhea occurrence were 3.18, 95% CI [1.49, 6.77] for children cared in group at home, 2.28, 95% CI [0.92, 5.67] for children cared in group in day-care homes and 2.54, 95% CI [1.21, 5.33] for children cared in day-care centers. Children that changed from any other type of child-care setting to child-care centers in the year preceding the study showed a risk even higher (OR 7.65, 95% CI [3.25, 18.02]. CONCLUSIONS: Group care increases the risk of acute diarrhea whatsoever the specific setting.

    Full Text Available BACKGROUND: Recent molecular studies have revealed a highly complex bacterial assembly in the canine intestinal tract. There is mounting evidence that microbes play an important role in the pathogenesis of acute and chronic enteropathies of dogs, including idiopathic inflammatory bowel disease (IBD. The aim of this study was to characterize the bacterial microbiota in dogs with various gastrointestinal disorders. METHODOLOGY/PRINCIPAL FINDINGS: Fecal samples from healthy dogs (n = 32, dogs with acute non-hemorrhagic diarrhea (NHD; n = 12, dogs with acute hemorrhagic diarrhea (AHD; n = 13, and dogs with active (n = 9 and therapeutically controlled idiopathic IBD (n = 10 were analyzed by 454-pyrosequencing of the 16S rRNA gene and qPCR assays. Dogs with acute diarrhea, especially those with AHD, had the most profound alterations in their microbiome, as significant separations were observed on PCoA plots of unweighted Unifrac distances. Dogs with AHD had significant decreases in Blautia, Ruminococcaceae including Faecalibacterium, and Turicibacter spp., and significant increases in genus Sutterella and Clostridium perfringens when compared to healthy dogs. No significant separation on PCoA plots was observed for the dogs with IBD. Faecalibacterium spp. and Fusobacteria were, however, decreased in the dogs with clinically active IBD, but increased during time periods of clinically insignificant IBD, as defined by a clinical IBD activity index (CIBDAI. CONCLUSIONS: Results of this study revealed a bacterial dysbiosis in fecal samples of dogs with various GI disorders. The observed changes in the microbiome differed between acute and chronic disease states. The bacterial groups that were commonly decreased during diarrhea are considered to be important short-chain fatty acid producers and may be important for canine intestinal health. Future studies should correlate these observed phylogenetic differences with functional changes in the intestinal

    AIM: Racecadotril is a specific enkephalinase inhibitor that exhibits intestinal antisecretory activity without affecting intestinal transit. Loperamide is an effective anti-diarrheal agent, but it usually induces constipation. This study is to compare the efficacy, safety, and tolerability of racecadotril versus Ioperamide in the outpatient treatment of acute diarrhea in adults.METHODS: A two-center, randomized, parallel-group,single-blind study was carried out to compare the efficacy,tolerability, and safety of racecadotril (100 mg thrics daily)and Ioperamide (2.0 mg 2 twics daily) in 62 adult patients suffering from acute diarrhea. The main efficacy criterion used was the duration of diarrhea after beginning the treatment (in hours). Other signs and symptoms were also evaluated.RESULTS: The clinical success rates for these antidiarrheal treatments were 95.7% and 92.0% for racecadotril and Ioperamide respectively. Patients on racecadotril had a median duration of diarrhea of 19.5 h compared with a median of 13 h for patients on Ioperamide.Rapid improvement in anal burn and nausea was found for each drug. However, more patients on Ioperamide suffered from reactive constipation (29.0% vs 12.9%).Itching, another adverse event was notably higher in the racecadotril group (28.6% vs 0%). With regard to other adverse events, the two medications showed similar occurrence rates and similar concomitant medication usage rates.CONCLUSION: Racecadotril and Ioperamide are rapid,equally effective treatments for acute diarrhea in adults,but Ioperamide treatment is associated with a higher incidence of treatment-related constipation.

    To examine the relationship between measures of mother's caretaking, practice and individual agency on acute diarrhea and respiratory tract infections (ARTIs) of Indonesian children. Using population-based household data from the Indonesian Demographic Health Surveys for 2002-2003 (n = 9,151 children) and 2007 (n = 9,714 children), we selected 28 indicators related to mother' caretaking, and applied principal component analysis to derive indices for access to care, practice and experience, and agency. The association between index quartiles (level 1-4) and the prevalence of diarrhea and ARTIs in the youngest child family size, child's age and sex, immunization status and received vitamin A supplementation. Moderate levels (level 3) of practice and experience were associated with decreased diarrheal risk (adjusted OR 0.86, 95 % CI 0.75-0.98), but not for ARTIs. Children of mothers with higher levels (level 4) of agency were protected against both diarrhea (adjusted OR 0.68, 95 % CI 0.60-0.77) and ARTIs (adjusted OR 0.77, 95 % CI 0.66-0.91). Stratified analyses with child's age and mother's education, and tests of interaction, showed that agency had a stronger effect on diarrhea and ARTIs prevalence in children child health.

Using population-based household data from the Indonesian Demographic Health Surveys for 2002-2003 (n = 9,151 children) and 2007 (n = 9,714 children), we selected 28 indicators related to mother' caretaking, and applied principal component analysis to derive indices for access to care, practice and experience, and agency. The association between index quartiles (level 1-4) and the prevalence of diarrhea and ARTIs in the youngest child <5 years of age was assessed with multivariate logistic regression adjusting for socioeconomic status, residence type, mother's age and education, family size, child's age and sex, immunization status and received vitamin A supplementation. Moderate levels (level 3) of practice and experience were associated with decreased diarrheal risk (adjusted OR 0.86, 95 % CI 0.75-0.98), but not for ARTIs. Children of mothers with higher levels (level 4) of agency were protected against both diarrhea (adjusted OR 0.68, 95 % CI 0.60-0.77) and ARTIs (adjusted OR 0.77, 95 % CI 0.66-0.91). Stratified analyses with child's age and mother's education, and tests of interaction, showed that agency had a stronger effect on diarrhea and ARTIs prevalence in children <2 years of age. Maternal caretaking, especially agency, is strongly associated with lower prevalence of diarrhea and ARTIs in younger children. Interventions specifically designed to promote maternal autonomy and decision-making may lead to improved child health.

    Full Text Available Acute respiratory distress syndrome (ARDS is closely correlated with infection. Severe infection, e.g., sepsis and septic shock, can result in ARDS. Ventilator associated pneumonia (VAP is one of the common complications in ARDS related infection. As regards ARDS related infection, community acquired infection (CAI is different from hospital acquired infection (HAI in bacterial spectrum. The former is mainly caused by Streptococcus pneumonia, Hemophilus influenzae, Moraxelle catarrhalis, atypical pathogens and Klebsiella pneumoniae. However, HAI is mainly caused by Pseudomonas aeruginosa, Acinetobacter baumanii, methicillin-resistant Staphylococcus aureus(MRSA, and other drug-resistant bacteria. The drug-resistant bacterial infection not only makes treatment difficult, but also leads to an increase in mechanical ventilation time, length of ICU stay, mortality rate, and medical costs. The present paper has reviewed the relationship between ARDS and infection, therapeutic principles and measures of ARDS related infection, and introduced the optimal strategy of anti-infectious treatment of ARDS.

    In a double-blind, controlled randomized trial, 88 adult patients with acute diarrhea (more than three watery stools per day) received either 400 mg of nifuroxazide twice daily or placebo for 5 days. The mean duration of diarrhea in the nifuroxazide group was 2.09 days versus 3.26 days in the placebo group (p less than 0.004). The number of bowel movements per day diminished and mucus disappeared more quickly in patients treated by nifuroxazide than in patients of the placebo group. Nifuroxazide was well tolerated and no side effects were observed. Nifuroxazide is an effective therapy for acute diarrhea and can be prescribed from the onset of diarrhea without waiting for stool culture results which can be late or negative. PMID:2666238

    Racecadotril (acetorphan) is a neutral endopeptidase (NEP) inhibitor with known antidiarrheal activity in animals and humans; however, in humans, it suffers from shortcomings that might be improved with newer drugs in this class that have progressed to the clinic for nonenteric disease indications. To identify potentially superior NEP inhibitors with immediate clinical utility for diarrhea treatment, we compared their efficacy and pharmacologic properties in a rat intestinal hypersecretion model. Racecadotril and seven other clinical-stage inhibitors of NEP were obtained or synthesized. Enzyme potency and specificity were compared using purified peptidases. Compounds were orally administered to rats before administration of castor oil to induce diarrhea. Stool weight was recorded over 4 hours. To assess other pharmacologic properties, select compounds were orally administered to normal or castor oil-treated rats, blood and tissue samples collected at multiple time points, and active compound concentrations determined by mass spectroscopy. NEP enzyme activity was measured in tissue homogenates. Three previously untested clinical NEP inhibitors delayed diarrhea onset and reduced total stool output, with little or no effect on intestinal motility assessed by the charcoal meal test. Each was shown to be a potent, highly specific inhibitor of NEP. Each exhibited greater suppression of NEP activity in intestinal and nonintestinal tissues than did racecadotril and sustained this inhibition longer. These results suggest that newer clinical-stage NEP inhibitors originally developed for other indications may be directly repositioned for treatment of acute secretory diarrhea and offer advantages over racecadotril, such as less frequent dosing and potentially improved efficacy.

    2012-02-01

    Full Text Available Background Diarrhea is the major cause of morbidity and mortality in children. Probiotics can decrease the frequency and duration of diarrhea. There are two types of probiotics, live and tyndallized. Tyndallized probiotics have been sterilized, so they are unable to produce active metabolites, but may have an effect on human immunity. Objective To evaluate the effectiveness of supplementing WHO standard therapy with tyndallized probiotics in children with acute, watery diarrhea. Methods We performed a randomized, single-blind, controlled trial in children aged 3-60 months who were diagnosed with acute, watery diarrhea at Gunungsitoli General Hospital, Nias, North Sumatera. Subjects were collected by consecutive sampling by way of parent interviews. Results One hundred subjects with acute, watery diarrhea were divided into 2 groups of 50. One group was treated with only WHO standard therapy for acute, watery diarrhea. The other group was treated by WHO standard therapy with the addition of tyndallized probiotics. There were no significant differences in basic characteristics between the two groups. Diarrheal duration for the group receiving WHO standard therapy only was 3.95 ± 1.3 days, while that of the group receiving both WHO standard therapy and tyndallized probiotics was 4.6 ± 2.3 days (P > 0.05. Diarrheal frequency on the fifth day in the WHO standard therapy group was 1.90 ± 0.99 times per day, while that of the tyndallized probiotic group was 1.56 ± 0.67 times per day (P > 0.05. Conclusion There were no significant differences between WHO standard therapy alone and WHO standard therapy with the addition of tyndallized probiotics for decreasing the duration and frequency of diarrhea in children.[Paediatr Indones. 2012;52:91-4].

    Parvoviruses cause a variety of mild to severe symptoms or asymptomatic infections in humans and animals. During a viral metagenomic analysis of feces from children with acute diarrhea in Burkina Faso, we identified in decreasing prevalence nucleic acids from anelloviruses, dependoviruses, sapoviruses, enteroviruses, bocaviruses, noroviruses, adenoviruses, parechoviruses, rotaviruses, cosavirus, astroviruses, and hepatitis B virus. Sequences from a highly divergent parvovirus, provisionally called bufavirus, were also detected whose NS1 and VP1 proteins showed parvoviruses. Four percent of the fecal samples were PCR positive for this new parvovirus, including a related bufavirus species showing only 72% identity in VP1. The high degree of genetic divergence of these related genomes from those of other parvoviruses indicates the presence of a proposed new Parvoviridae genus containing at least two species. Studies of the tropism and pathogenicity of these novel parvoviruses will be facilitated by the availability of their genome sequences.

    INTRODUCTION: Persistent diarrhea has high impact on infantile morbidity and mortality rates in developing countries. Several studies have shown that 3 to 20% of acute diarrheal episodes in children under 5 years of age become persistent. DEFINITION: Persistent diarrhea is defined as an episode that lasts more than 14 days. ETIOLOGY: The most important agents isolated in persistent diarrhea are: Enteropathogenic E. coli (EPEC), Salmonella, Enteroaggregative E. coli (EAEC), Klebisiella and Cryptosporidium. CLINICAL ASPECTS: In general, the clinical characteristics of patients with persistent diarrhea do not change with the pathogenic agent. Persistent diarrhea seems to represent the final result of a several insults a infant suffers that predisposes to a more severe episode of diarrhea due to a combination of host factors and high rates of enviromental contamination. Therefore, efforts should be made to promptly treat all episodes of diarrhea with apropriate follow-up. THERAPY: The aim of the treatment is to restore hydroelectrolytic deficits and to replace losses until the diarrheal ceases. It is possible in the majority of the cases, using oral rehydration therapy and erly an appropriate type of diet. PREVENTION: It is imperative that management strategies also focus on preventive aspects. The most effective diarrheal prevention strategy in young infants worldwide is promotion of exclusive breast feeding. PMID:14676915

    2016-01-01

    Background: Acute diarrhea remains the serious problem in developing countries, especially among children under 5 years of age. Currently, only two or three common diarrhea pathogens were screened at most hospitals in China. The aim of this study was to provide a wide variety of diarrhea pathogens and their antimicrobial resistance patterns in children under 5 years of age. Methods: Totally 381 stool samples collected from Tongji Hospital between July 1, 2014 and June 30, 2015 were tested by culture and/or polymerase chain reaction for eight kinds of bacteria and five kinds of viruses. An antimicrobial sensitivity test was performed using dilution method recommended by the Clinical and Laboratory Standards Institute. Results: Viral infections were mainly identified in infants (0–11 months), whereas bacterial infections were more prevalent in the age of 24–59 months. About 69.8% of samples were positive for at least one pathogen, 51.7% of samples were virus positive, followed by bacteria positive cases (19.4%), and 12.6% of cases displayed co-infections with two viruses or a virus and a bacterium. Rotavirus was the most prevalent pathogen, followed closely by norovirus, while Salmonella was the most commonly isolated bacteria, followed by diarrheagenic Escherichia coli (DEC) and Campylobacter. More than 40% of Salmonella spp. and DEC isolates were resistant to first-line antibiotics (ampicillin, trimethoprim-sulfamethoxazole, and tetracycline). Around 10% of Salmonella spp. isolates were resistant to ceftriaxone and ciprofloxacin simultaneously. Campylobacter spp. displayed high resistance to ciprofloxacin but kept low resistance to azithromycin and doxycycline. Conclusions: The etiology of acute diarrhea varies in children of different age groups. The high frequency of infection with viruses suggests the urgent demand for new viral vaccine development. Proper use of antibiotics in the treatment of acute diarrhea is crucial due to the high level of antibiotic

China experiences a substantial portion of the global burden of diarrhea, but the impact of zinc treatment among children under five has not been well documented by previously published systematic reviews on the topic. We therefore conducted a systematic literature review, which included an exhaustive search of the Chinese literature, in an effort to update previously published estimates of the effect of therapeutic zinc. We conducted systematic literature searches in various databases, including the China National Knowledge Infrastructure (CNKI, and abstracted relevant data from studies meeting our inclusion and exclusion criteria. We used STATA 12.0 to pool select outcomes and to generate estimates of percentage difference and relative risk comparing outcomes between zinc and control groups. We identified 89 Chinese and 15 non-Chinese studies for the review, including studies in 10 countries from all WHO geographic regions, and analyzed a total of 18,822 diarrhea cases (9469 zinc and 9353 control. None of the included Chinese studies had previously been included in published pooled effect estimates. Chinese and non-Chinese studies reported the effect of therapeutic zinc supplementation on decreased episode duration, stool output, stool frequency, hospitalization duration and proportion of episodes lasting beyond three and seven days. Pooling Chinese and non-Chinese studies yielded an overall 26% (95% CI: 20%−32% reduction in the estimated relative risk of diarrhea lasting beyond three days among zinc-treated children. Studies conducted in and outside China report reductions in morbidity as a result of oral therapeutic zinc supplementation for acute diarrhea among children under five years of age.

    Full Text Available Introduction & Objective: Diarrhea is the most common cause of morbidity and mortality in all age groups, especially children, the elderly and immunocompromised patients. Various studies have been reported regarding the relationship between the children acute diarrhea and Aeromonashydrophila and Yersinia enterocolitica. This study aimed to investigate the prevalence of the bacteria and their sensitivity to common antibiotics and the prevalence of virulence genes in the bacteria in Hamadan, Iran. Materials & Methods: In this study, 120 stool samples collected from children less than 10 years of age with acute diarrhea were examined for Aeromonashydrophila and Yersinia enterocolitica. Identification of the bacteria was performed by biochemical reactions and PCR using 16S rRNA genes. Moreover, the prevalence of virulence genes earA and hyl of Aeromonashydrophila and ail and ystB genes of Yersinia enterocolitica were investigated using PCR. Antibiotic susceptibility of isolated bacteria was performed by disk diffusion method. Results: Out of 120 stool samples, 2 (1.7 % Aeromonashydrophila and 3 (2.5% Yersinia enterocolitica were isolated. All isolates of Aeromonashydrophila were sensitive to the chloramphenicol, co-trimoxazole, gentamicin, meropenem, amikacin and 50% of isolates were sensitive to the ceftriaxone and azithromycin. All Aeromonashydrophila isolates were resistant to erythromycin. All isolates of Yersinia enterocolitica were sensitive to the chloramphenicol, co-trimoxazole and meropenem. The 33.3% of the isolates were sensitive to gentamicin and amikacin and 66.6% of them were susceptible to ceftriaxone. However, all of Yersinia enterocolitica isolates were resistant to erythromycin and azithromycin. The prevalence aerA and hyl genes in Aeromonashydrophila were reported 100% and 50%, respectively. The prevalence of ail and ystB genes in Yersinia enterocolitica was reported as 66.6%. Conclusions: Identification and analysis of

    Background: Probiotic therapies with different strains demonstrated some beneficial effects, although some studies did not show any significant effects. This study assessed systematically the current knowledge on the effect of probiotic bacteria on duration of acute rotavirus diarrhea in children compared with control. Methods: The PubMed, Cochrane Controlled Trial Register (CCTR) and Ovid (Wolters Kluwer Health) were searched between 1980 to June 15, 2013. Randomized controlled trials including the administration of probiotics for treatment of rotavirus diarrhea in infants and children were reviewed. Results: A total number of 1244 articles were found through the aforementioned search. 203 articles were selected after the first screening of title and abstract. The intervention group included subjects who received probiotic strains and dosage in any conditions. Placebo or any similar vehicle without probiotic was used in the controlled trials. Finally, 14 articles were selected. The outcomes from each study were considered in the duration of diarrhea. Statistical analyses were performed with Stata software. The pooled estimate of efficacy of probiotics in prevention or treatment of disease yielded in all studies a mean difference of 0.41 (CI 95%: -0.56 to –0.25; p<0.001). The pooled estimate of efficacy of lactobacillus rhamnosus GG and other probiotics significantly reduced the duration of diarrhea. Among trials, the overall reduction of LGG was 0.47 (CI 95%: -0.80 to -0.14; P= 0.020). Conclusion: In conclusion, probiotics exert positive effect in reducing the duration of acute rotavirus diarrhea compared with control. PMID:26644891

    Fecal concentrations of pyruvate kinase isoform M2 (M2-PK) and calprotectin (FC) serve as biomarkers of inflammation of gastrointestinal mucosa. The value of M2-PK in discriminating between patients with viral and bacterial acute diarrhea (AD) is currently unknown. We analyzed M2-PK and FC concentrations in fifty hospitalized children with AD (29 of which were caused by rotavirus and 21 by Salmonella enteritidis) as well as 32 healthy subjects. There was no difference in the areas under the receiver operating characteristic curves plotted for the two tests in differentiating rotaviral from bacterial AD. The sensitivity and specificity of M2-PK at optimal cut-off (20 U/g) were 75.9% and 71.4%, respectively. M2-PK and FC had similar values in distinguishing between children with AD caused by rotavirus and Salmonella enteritidis. The performance of both tests in hospitalized patients did not meet the needs of everyday clinical practice. Moreover, no advantage of fecal tests over the measurement of CRP was documented.

    Full Text Available Although dehydration from diarrhea is a leading cause of morbidity and mortality in children under five, existing methods of assessing dehydration status in children have limited accuracy.To assess the accuracy of point-of-care ultrasound measurement of the aorta-to-IVC ratio as a predictor of dehydration in children.A prospective cohort study of children under five years with acute diarrhea was conducted in the rehydration unit of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b. Ultrasound measurements of aorta-to-IVC ratio and dehydrated weight were obtained on patient arrival. Percent weight change was monitored during rehydration to classify children as having "some dehydration" with weight change 3-9% or "severe dehydration" with weight change > 9%. Logistic regression analysis and Receiver-Operator Characteristic (ROC curves were used to evaluate the accuracy of aorta-to-IVC ratio as a predictor of dehydration severity.850 children were enrolled, of which 771 were included in the final analysis. Aorta to IVC ratio was a significant predictor of the percent dehydration in children with acute diarrhea, with each 1-point increase in the aorta to IVC ratio predicting a 1.1% increase in the percent dehydration of the child. However, the area under the ROC curve (0.60, sensitivity (67%, and specificity (49%, for predicting severe dehydration were all poor.Point-of-care ultrasound of the aorta-to-IVC ratio was statistically associated with volume status, but was not accurate enough to be used as an independent screening tool for dehydration in children under five years presenting with acute diarrhea in a resource-limited setting.

    2008-07-01

    This review focuses on the efficacy of probiotics for diarrhea in children in different settings: day-care centers, diarrhea acquired in the hospital, antibiotic-associated diarrhea, and treatment of acute infectious diarrhea. For prevention of diarrhea acquired in day-care centers, 5 randomized and placebo-controlled trials have been published. Probiotics tested were Lactobacillus GG, Bifidobacterium lactis (alone or in combination with Streptococcus thermophilus), and Lactobacillus reuteri. The evidence of their efficacy in these settings is only modest: statistically significant for some strains only and in any case of minimal to mild clinical importance. Few trials have examined the potential role of probiotics in preventing the spread of diarrhea in hospitalized children, an event most commonly due to either rotavirus or Clostridium difficile, and they have yielded conflicting results. Overall, these studies provide only weak evidence on the efficacy of probiotics. On the other hand, a large number of trials on the role of probiotics in preventing the onset of antibiotic-associated diarrhea have been published. Most commonly employed probiotics were Lactobacillus GG, Bifidobacterium spp., Streptococcus spp., and the yeast Saccharomyces boulardii. In general, these trials do show clear evidence of efficacy, with the 2 most effective strains being Lactobacillus GG and S. boulardii. Today, we have a large number of published clinical trials on the role of probiotics in treating sporadic infectious diarrhea in children, and many of them are randomized, blinded, and controlled. They consistently show a statistically significant benefit and moderate clinical benefit of a few, well-identified probiotic strains-mostly Lactobacillus GG and S. boulardii, but also L. reuteri-in the treatment of acute watery diarrhea, primarily rotaviral, in infants and young children of developed countries. Such a beneficial effect seems to result in a reduction of diarrhea duration of

    ObjectiveTo investigate the development of lactose intolerance in neonates with non-infectious diarrhea and its association with diarrhea, and to evaluate the diagnostic values of fecal pH value and urine galactose determination for neonatal lactase deifciency.MethodsSeventy hospitalized neonates who developed non-infectious diarrhea between October 2012 and June 2015 were enrolled as the diarrhea group, and 162 hospitalized neonates without non-infectious diarrhea were enrolled as the non-diarrhea group. Test paper was used to determine fecal pH value. The galactose oxidase method was used to detect urine galactose. The neonates with positive galactose oxidase were diagnosed with lactase deficiency, and those with lactase deficiency and diarrhea were diagnosed with lactose intolerance. According to the results of urine galactose detection, 69 neonates in the diarrhea group who underwent urine galactose detection were classiifed into lactose intolerance group (45 neonates) and lactose tolerance group (24 neonates), and their conditions after treatment were compared between the two groups. The follow-up visits were performed for neonates with diarrhea at 3 months after discharge.ResultsFecal pH value and positive rate of urine galactose (65% vs 54%) showed no signiifcant differences between the diarrhea and non-diarrhea groups (P>0.05). Fecal pH value showed no signiifcant difference between the lactose intolerance and lactose tolerance groups (P>0.05), while the neonates in the lactose intolerance group had a signiifcantly longer time to recovery of defecation than those in the lactose tolerance group (P0.05)。乳糖不耐受和耐受组腹泻患儿大便pH值比较差异无统计学意义(P>0.05),乳糖不耐受患儿大便恢复时间比耐受组患儿长(P<0.05)。结论新生儿乳糖酶缺乏发生率高,易发生乳糖不耐受性腹泻。大便pH值测定对判断腹泻患儿乳糖不耐受意义不大。

    Full Text Available CONTEXT: Acute diarrhea is a common cause of hospitalization among children under 5 years of age. Knowing the prevalence and risk factors associated with the severity of acute diarrhea is essential to control morbidity and mortality. OBJECTIVE: Describe the prevalence of demographic, epidemiologic and clinical features of children under 6 years of age hospitalized for acute diarrhea, and investigate the association between these determinants and the severity of the diarrheic episode. METHOD: Retrospective, cross-sectional study, during the period from January, 2005 through December, 2008, in the municipality of Juiz de Fora, MG, Brazil. Files from 6,201 children from 0 to 6 years of age, hospitalized in two public teaching institutions (which account for 84% of all the hospitalizations in the municipality, were assessed. Acute diarrhea was defined as the presence of at least three evacuations of liquid or loose stools, within 24 hours, for a maximum period of 14 days. The patients with acute diarrhea were divided in two groups, according to disease severity, severe diarrhea being considered whenever hospitalization lasted for at least 4 days. Epidemiologic and clinical data were assessed and compared through the application of the chi-squared test and the binomial logistic regression model. RESULTS: The prevalence rate for admission due to acute diarrhea was 8.4%. The factors significantly associated with the severity of the diarrheic episode were: age under 6 months (P = 0.01, OR = 2.762; disease onset during fall (P = 0.033, OR = 1.742, presence of fever (P = 0.017, OR = 1.715 and antibiotic use during hospitalization (P = 0.000, OR = 3.872. CONCLUSIONS: Diarrhea is the third most common cause of hospitalization among children under 6 years of age in Juiz de Fora. Young age (under or equal to 6 months, fever, antibiotic use during hospitalization and disease onset during fall are risk factors associated with longer hospital stay.

    An outbreak of cholera began in Haiti in October of 2010. To understand the progression of epidemic cholera in Haiti, in April of 2012, we initiated laboratory-enhanced surveillance for diarrheal disease in four Haitian hospitals in three departments. At each site, we sampled up to 10 hospitalized patients each week with acute watery diarrhea. We tested 1,616 specimens collected from April 2, 2012 to March 28, 2013; 1,030 (63.7%) specimens yielded Vibrio cholerae, 13 (0.8%) specimens yielded Shigella, 6 (0.4%) specimens yielded Salmonella, and 63 (3.9%) specimens tested positive for rotavirus. Additionally, 13.5% of children < 5 years old tested positive for rotavirus. Of 1,030 V. cholerae isolates, 1,020 (99.0%) isolates were serotype Ogawa, 9 (0.9%) isolates were serotype Inaba, and 1 isolate was non-toxigenic V. cholerae O139. During 1 year of surveillance, toxigenic cholera continued to be the main cause of acute diarrhea in hospitalized patients, and rotavirus was an important cause of diarrhea-related hospitalizations in children.

    Previous case reports and retrospective studies suggest that pituitary dysfunction may occur after acute bacterial or viral meningitis. In this prospective study we assessed the pituitary functions, lipid profile and anthropometric measures in adults with acute bacterial or viral meningitis. Moreover, in order to investigate whether autoimmune mechanisms could play a role in the pathogenesis of acute meningitis-induced hypopituitarism we also investigated the anti-pituitary antibodies (APA) and anti-hypothalamus antibodies (AHA) prospectively. Sixteen patients (10 males, 6 females; mean ± SD age 40.9 ± 15.9) with acute infectious meningitis were included and the patients were evaluated in the acute phase, and at 6 and 12 months after the acute meningitis. In the acute phase 18.7% of the patients had GH deficiency, 12.5% had ACTH and FSH/LH deficiencies. At 12 months after acute meningitis 6 of 14 patients (42.8%) had GH deficiency, 1 of 14 patients (7.1%) had ACTH and FSH/LH deficiencies. Two of 14 patients (14.3%) had combined hormone deficiencies and four patients (28.6%) had isolated hormone deficiencies at 12 months. Four of 9 (44.4%) hormone deficiencies at 6 months were recovered at 12 months, and 3 of 8 (37.5%) hormone deficiencies at 12 months were new-onset hormone deficiencies. At 12 months there were significant negative correlations between IGF-I level vs. LDL-C, and IGF-I level vs. total cholesterol. The frequency of AHA and APA positivity was substantially high, ranging from 35 to 50% of the patients throughout the 12 months period. However there were no significant correlations between AHA or APA positivity and hypopituitarism. The risk of hypopituitarism, GH deficiency in particular, is substantially high in the acute phase, after 6 and 12 months of the acute infectious meningitis. Moreover we found that 6th month after meningitis is too early to make a decision for pituitary dysfunction and these patients should be screened for at least 12 months

    Full Text Available Background Enteritis caused by Campylobacter is considered as the most common acute bacterial diarrhea around the world. In most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. Objectives The purpose of the present study was to determine the prevalence and antibiotic resistance of campylobacter species among pediatrics of Hamadan city, Iran. Patients and Methods A total of 120 stool samples from children less than 10 years old were examined from January 2013 to December 2014 in Hamadan, Iran. The samples were incubated in Campy-Thio enrichment medium for 1 - 2 hours and then cultured on a specific medium; after that, the suspected colonies were analyzed for Campylobacter spp. identification by conventional tests. The identified species by biochemical methods were confirmed by polymerase chain reaction (PCR. Antimicrobial susceptibility testing was performed by disk agar diffusion (DAD method. Results Twelve (10% Campylobacter spp. from 120 stool samples were isolated including C. coli and C. jejuni. In the antibiotic susceptibility test, the most frequent resistance was observed to ciprofloxacin 8 (88.8%, followed by 7 (77.7% resistant strains to tetracycline, 7 (77.7% to erythromycin, 6 (66.6% to clindamycin, 5 (55.5% to meropenem, 4 (44.4% to gentamicin, 3 (33.3% to nalidixicacid and only 1 (11.1% to chloramphenicol. Conclusions Campylobacter is responsible for some important clinical problems such as enteritis and is also associated with meningitis and hemolytic-uremic syndrome. It is imperative to monitor the prevalence and antibiotic resistance of Campylobacter spp. as well as other the zoonotic bacteria.

    2008-01-01

    Full Text Available Background: Enteroaggregative Escherichia coli (EAEC is an emerging enteric pathogen that causes persistent diarrhea among infants, both in developing and industrialized countries. The EAEC strains adhere to epithelial cell surface, to the glass substratum and to each other in a distinctive stacked brick-formation. Thus, gold standard for identification of EAEC remains the HEp-2 cell adherence test, which is time consuming and requires specialized facilities. Aim: To evaluate the usefulness of quantitative biofilm assay to screen for EAEC from children with acute diarrhea. Materials and Methods: A total of 100 E. coli strains were collected from acute diarrheal cases from December 2005 to November 2006. The strains were screened for biofilm production using microtiter plate method. The biofilm in the microtiter plate was visualized after staining with crystal violet and was quantified using enzyme immunosorbent assay plate reader. The Aggregative plasmid and Heat stable toxin genes were evaluated by a multiplex polymerase chain reaction. The strains were identified as EAEC with an optical density at 570 nm (OD 570 > 0.2. Results: Of the total 100 Escherichia coli strains, 28 were positive by Polymerase Chain Reaction for two genes, AggR and EAST. Of the 28 PCR-positive strains screened for biofilm, 25 (89.2% showed positive results by microtiter plate method. Conclusion: The quantitative biofilm assay using microtiter plate is convenient and economical and can be used as a screening method to screen E. coli isolates from acute diarrheal cases. The best use of this test is to screen large number of isolates quickly, and if positive this can be confirmed by multiplex PCR for AggR and EAST genes. This assay may contribute to demonstrating the true incidence of EAEC with and without AggR among clinically isolated E. coli strains, which can cause acute diarrhea.

    Full Text Available Background: Acute gastroenteritis is a major cause of morbidity and mortality among children in developing countries. Rotaviruses are recognized as the most common etiologic factors of gastroenteritis. In this study, we determined the epidemiologic features, clinical symptoms and molecular structure of rotavirus VP4(P genotypes in children with acute diarrhea in Bahrami Hospital in Tehran Iran, during 2009 for justifying the routine use of rotavirus vaccines in children. Methods: One hundred fifty fecal samples from 150 children with acute diarrhea in Bahrami Pediatric Hospital in Tehran, Iran were collected from January to December 2009. The patients’ mean age was 20.90+18.19 years (ranging from 1 month to 14 years. Fecal samples were transported on ice to the laboratory of virology department of Pasture Institute of Iran. The demographic and clinical data for each case were entered in an author-devised questionnaire. Group A rotavirus was detected by dsRNA-PAGE. Subsequently, rotavirus genotyping (VP4 was performed by semi-nested multiple RT-PCR and the phylogenetic tree of the Rotavirus nucleotides was constructed. The data were analyzed by statistical tests including Wilcoxon signed and Mann-Whitney U. Results: Rotavirus was isolated in 19.3% of the samples, more than 90% of which had long RNA patterns. The predominant genotype (VP4 was P[8] (86% and other genotypes respectively were P[6] (6.9% and P[4] (6.9%. Conclusion: A high prevalence of the P[8] genotype was found to be the cause of acute diarrhea. The analysis of P[8] genotype sequence showed a high level of similarity of the virus in this study with those of other Asian countries.

(0.4%). Infection with more than one pathogen occurred in 96 (37.9%) patients. Rotavirus and enteric pathogenic Esc. coli were frequent. Concurrent infection by more than one parasite occurred in 18.6% of the infants. Most rotavirus infections (76.7%) occurred in infants under 12 months. Vomiting, severe dehydration and fever were frequent in children with rotavirus infection. At least one fecal marker of inflammatory diarrhea was registered in patients with bacterial infection. To our knowledge, this is first report of P. alcalifaciens associated with infantile diarrhea in Colombia and the first description of Esc. coli O157:H7 and Y. enterocolitica in our region.

    @@ The severe acute respiratory syndrome (SARS) that emerged 2002-2003 and apparently again 2004 (reported by the news media on December 27, 2003) as the first confirmed case by the World Health Organization (WHO)1,2 raised awareness of emerging infectious diseases.3 Every year there are both new and old infectious diseases emerging as potential pandemic agents.4-6 However, few of these diseases receive the public attention and concern expressed as occurred during the emergence of SARS. Much of this concern was a result of the rapid spread of the novel coronavirus (CoV) to different regions of the world and its high infectivity, especially for health care workers (HCW).3 In many ways, the high percent of HCW infected is a warning of the potential hazards of old and emerging infectious diseases.6 However, SARS was not the only disease (e.g. Monkeypox) that emerged in 2003,3 rather it received the greatest attention.

    Full Text Available Anti-N-methyl-d-aspartate receptor encephalitis has become an increasingly recognized etiology of acute psychosis in young patients. The diverse constellation of symptoms allows for misdiagnosis as an infectious, psychological, or toxicological entity resulting in delays in treatment with increasing morbidity. We describe a case of anti-NMDAR encephalitis that was a particular challenge to diagnose. Practitioners should maintain a high index of suspicion for anti-NMDAR and related neuroautoimmune syndromes, especially in young patients that present with acute mental status decline or dyskinesia.

    Tanja Opriessnig

    Full Text Available Porcine epidemic diarrhea virus emerged in North America in April 2013 and has since been identified in 30 U.S. States, Canada and Mexico. The rapid spread of PEDV has raised concerns about the role of feed and particularly pork-by-product components such as spray-dried porcine plasma (SDPP in PEDV transmission. The aim of this study was to determine the infectivity of PEDV RNA present in commercial SDPP. Specifically, 40 3-week-old PEDV naïve pigs were randomly assigned to one of five treatment groups. At day post inoculation (dpi 0, NEG-CONTROL pigs were sham-inoculated, PEDV-CONTROL pigs received cell culture propagated PEDV, and SDPP-CONTROL pigs were switched to a diet with 5% SDPP containing 5.1±0.1 log10 PEDV RNA copies/g. To evaluate a potential positive effect of anti-PEDV antibodies in SDPP on PEDV challenge, four days prior to PEDV challenge the pigs in the SDPP-PEDV group were switched to and remained on a 5% SDPP diet through dpi 28. Another group, EGG-PEDV, was orally administered a commercial egg-derived liquid PEDV globulin product from dpi -4 through 6. All PEDV-CONTROL pigs began shedding PEDV in feces by dpi 3 and seroconverted between dpi 7 and 14, whereas pigs in NEG-CONTROL and SDPP-CONTROL groups remained PEDV RNA negative and did not seroconvert to PEDV for the study duration. This indicates no evidence of infectivity of the PEDV RNA in the SDPP lot utilized. Furthermore, under the study conditions SDPP or egg-derived liquid PEDV globulin addition did not significantly alter PEDV-shedding or overall disease course after experimental challenge.

    Full Text Available BACKGROUND: The primary objective was to describe infectious complications in children with acute myeloid leukemia from presentation to the healthcare system to initiation of chemotherapy and to describe how these infections differ depending on neutropenia. METHODS: We conducted a retrospective, population-based cohort study that included children and adolescents with acute myeloid leukemia diagnosed and treated at 15 Canadian centers. We evaluated infections that occurred between presentation to the healthcare system (for symptoms that led to the diagnosis of acute myeloid leukemia until initiation of chemotherapy. RESULTS: Among 328 children, 92 (28.0% were neutropenic at presentation. Eleven (3.4% had sterile-site microbiologically documented infection and four had bacteremia (only one Gram negative. Infection rate was not influenced by neutropenia. No child died from an infectious cause prior to chemotherapy initiation. CONCLUSION: It may be reasonable to withhold empiric antibiotics in febrile non-neutropenic children with newly diagnosed acute myeloid leukemia until initiation of chemotherapy as long as they appear well without a clinical focus of infection. Future work could examine biomarkers or a clinical score to identify children presenting with leukemia and fever who are more likely to have an invasive infection.

Methods Thirty people for health examination as controls, forty-eight patients with infectious diarrhea and thirty patients with diarrhea-predominant irritable bowel syndrome (D-IBS) were recruited. Stool sample (5 ~ 10 g) was collected in each people to determine fecal calprotectin by an emzyme-linked immunosorbent assay; meanwhile the case history and clinical data were collected simultaneously. Results The fecal calprotectin concentration in infectious diarrhea patients (515.21 μg/g, n = 48) was significantly higher than that in the healthy controls (25.18 μg/g, n = 30)and the D-IBS patients (35.02 μg/g,n = 30, P <0. 001 ). There was no statistical significance of calprotectin concentration between D-IBS patieuts and healthy controls (P > 0. 05). The level of FCP in infectious diarrhea patients was related with the quantity of fecal leukoeytes (r =0. 761 ). When the cut-off limit of fecal calprotectin was set as 100 μg/g, its diagnostic sensitivity of infectious diarrhea was 85.4

    Full Text Available Acute kidney injury (AKI is becoming more prevalent among hospitalized children, its etiologies are shifting, and new treatment modalities are evolving; however, diarrhea-associated hemolytic uremic syndrome (D+HUS remains the most common primary disease causing AKI in young children. Little has been published about acute renal replacement therapy (ARRT and its challenges in this population. We describe our single center's experience managing 134 pediatric patients with D+HUS out of whom 58 (43% required ARRT over the past 16 years. In our cohort, all but one patient were started on peritoneal dialysis (PD. Most patients, 47 (81%, received acute PD on a pediatric inpatient ward. The most common recorded complications in our cohort were peritoneal fluid leaks 13 (22%, peritonitis 11 (20%, and catheter malfunction 5 (9%. Nine patients (16% needed surgical revision of their PD catheters. There were no bleeding events related to PD despite a mean platelets count of 40.9 (±23.5 × 103/mm3 and rare use of platelets infusions. Despite its methodological limitations, this paper adds to the limited body of evidence supporting the use of acute PD as the primary ARRT modality in children with D+HUS.

    Pseudomembranous colitis (PMC) usually manifests asfever and diarrhea in hospitalized patients treated withsystemic antibiotics. We described a case of PMC withintestinal obstruction but without diarrhea. A 60-yearold man was hospitalized for chemotherapy for the treatment of Burkitt lymphoma of the stomach. The patient became febrile and complained of crampy abdominal pain during the post-chemotherapy nadir. Plain abdominal radiography showed some intestinal gas and niveau. Because stool cytotoxin assay for clostridium difficile was positive and colon fiberscopic examination showed a pseudomembrane at the left side of the colon,and a diagnosis of PMC was made. Treatment with intracolonic vancomycin administration by colonoscopy and nasoileus tube was successful. Physicians should take into account the possibility of bowel obstruction due to PMC occurring in patients undergoing chemotherapy and perform emergency colonoscopy examination of suspected cases.

The analysis is performed from a United Kingdom National Health Service (NHS perspective.Methods: A decision tree model has been developed in Microsoft® Excel. The model is populated with the best available evidence. Deterministic and probabilistic sensitivity analyses (PSA have been performed. Health effects are measured as quality-adjusted life years (QALYs and the model output is cost (2011 GBP per QALY. The uncertainty in the primary outcome is explored by probabilistic analysis using 1000 iterations of a Monte Carlo simulation.Results: Deterministic analysis results in a total incremental cost of –£379 in favor of racecadotril and a total incremental QALY gain in favor of racecadotril of +0.0008. The observed cost savings with racecadotril arise from the reduction in primary care reconsultation and secondary referral. The difference in QALYs is largely attributable to the timely resolution of symptoms in the racecadotril arm. Racecadotril remains dominant when base case parameters are varied. Monte Carlo simulation and PSA confirm that racecadotril is the dominant treatment strategy and is almost certainly cost effective, under the central assumptions of the model, at a

    Full Text Available Abstract Background Adjuvant therapy to ORT with probiotic bacteria for infants with acute watery diarrhea has been under active investigation. Most studies have been done in the developed world showing benefit only for viral mild gastroenteritis. We evaluated the effect of a milk formula containing one billion (109 cfu/ml of Lactobacillus casei strain GG (LGG upon duration and severity of diarrhea in infants in an environment with more severe acute diarrhea, where etiologic agents other than rotavirus are involved more frequently, and where mixed infections are more prevalent. Methods Male infants aged 3–36 months brought for treatment of acute watery diarrhea of less than 48 hours were eligible. After rehydration was completed with the WHO's oral rehydration solution, patients were randomly assigned to receive a milk formula either containing LGG or not. Stool volume was periodically measured using a devise suited to collect stools separate from urine. Duration of diarrhea was estimated based on stools physical characteristics. Results Eighty nine patients received the placebo milk formula and ninety received the LGG containing formula. Both groups were comparable in their baseline characteristics. Total stool output was significantly larger (p = 0.047 in the LGG group (247.8 ml/kg than in the placebo group (195.0 ml/kg. No significant differences were found in duration of diarrhea (58.5 hours with LGG vs. 50.4 hours with placebo, rate of treatment failure (21.1% with LGG vs. 18.0% with placebo, and proportion of patients with unresolved diarrhea after 120 hours (12.2% with LGG vs. 12.5% with placebo. The rate of stools with reducing substances after 24 hours of treatment increased significantly in both groups (from 41.4% to 72.2% with LGG and from 45.9% to 68.0% with placebo. Conclusion This study did not show a positive effect of LGG on the clinical course of acute watery diarrhea. Positive beneficial effects of LGG, as had been reported

    Chronic diarrhea is usually associated with a number of non-infectious causes. When definitive treatment is unavailable, symptomatic drug therapy is indicated. Pharmacologic agents for chronic diarrhea include loperamide, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists, diosmectite, cholestyramine, probiotics, antispasmodics, rifaximin, and anti-inflammatory agents. Loperamide, a synthetic opiate agonist, decreases peristaltic activity and inhibits secretion, resulting in the reductio...

    Introduction Diarrhea is a leading killer of children, accounting for 9% of all deaths among under-five children worldwide. WHO protocol deviation in management of diarrheas in children is likely due to various reasons. Aim To study the prescription practices, regarding adherence to WHO protocol and deviations, in the management of acute diarrhea in children presenting at a tertiary care hospital and its impact on the outcome. Materials and Methods This was a prospective observational hospital based study at a tertiary care carried out over a 12-month period including all cases of acute diarrhea (defined as 3 or more loose stools in last 24 hours) in children belonging to the age group of 6 months to 5 years. Patients were followed up on day 3,7,14 and 28 from the day of presentation. Software SPSS Version 17.0 was used for analysis. Correlation regression analysis was used to study predictiveness of different variables affecting outcome. Results In this study, 447 children aged between 6 months and 5 years were enrolled, of which 45 cases were lost in follow-up and excluded. The median age was 14 months. Some deviation from WHO protocol was noted in 78.4% of the cases. Most common deviations from WHO protocol were addition of probiotics (78.1% of cases) and addition of race cadotril (15.9% of cases). Inadvertent use of antibiotics in diarrhea was noted in 12.2% of cases. Presence of fever was strong predictor for use of antibiotics. Cases of early recovery within 3 days of presentation were higher in WHO protocol deviation group. Use of probiotics had statistically significant association with early recovery. Conclusion In diarrhea management, WHO protocol deviation is common. Probiotics are likely to help in early recovery. PMID:27437317

    Diarrhea-predominant irritable bowel syndrome (IBS) is diagnosed through clinical criteria after excluding "organic" conditions, and can be precipitated by acute gastroenteritis. Cytolethal distending toxin B (CdtB) is produced by bacteria that cause acute gastroenteritis, and a post-infectious animal model demonstrates that host antibodies to CdtB cross-react with vinculin in the host gut, producing an IBS-like phenotype. Therefore, we assessed circulating anti-CdtB and anti-vinculin antibod...

    Background The world health organization guidelines for treatment of diarrhea in children emphasize on continued feeding together with prescription of oral rehydration solution (ORS) and supplementary zinc therapy. However, conflicting viewpoints exist regarding the optimal diet and dietary ingredients for children with diarrhea. Moreover, few studies have investigated the effect of rice soup along with ORS in the treatment of this disease. Objectives This study aimed to explore effects of simultaneous taking of glucose oral rehydration solution (G-ORS) and rice soup in the treatment of acute diarrhea in 8 to 24-month-old children. Patients and Methods This single-blind controlled clinical trial was conducted in the pediatric ward of 22nd of Bahman hospital, Gonabad, Iran between June 2013 and February 2014. Forty children aged 8-24 months with acute diarrhea were randomly assigned into an intervention group (G-ORS plus rice soup group) comprising 20 babies and a control group (G-ORS) of 20 children based on balanced blocking randomization. The variables under investigation were diarrhea duration, patient hospitalization, need for intravenous (IV) fluids and stool output frequency. Data was analyzed using independent samples t and chi-square test. Results At the end of study, the time for treating acute watery diarrhea in the intervention and control groups were 21.10 ± 8.81 and 34.55 ± 5.82 hours (P < 0.001) and hospital stay were 34.05 ± 6.62 and 40.20 ± 6.32 hours (P = 0.005). Moreover, stool output frequency were 4.20 ± 0.95 and 8.00 ± 1.37 (P < 0.001) in the first 24 hours, and 2.18 ± 0.60 and 2.80 ± 0.76 (P = 0.03) in the second 24 hours of treatment in intervention and control groups, respectively. Conclusions Rice soup regimen was highly effective and inexpensive in the treatment of acute diarrhea in children. Thus, in addition to the common treatment by G-ORS, rice soup can be consumed simultaneously with G-ORS.

    Objective To observe the clinical efficacy and safety of Brad's yeast in the prevention of secondary diarrhea in neonatal infectious pneumonia. Methods 120 cases of children fit the diagnosis of neonatal infectious pneumonia were assigned to observation group (62 cases) and control group (58 cases). Both groups were given antibiotics and symptomatic supportive treatment, while the observation group was given additional full course of oral administration of Brad's yeast. Children with secondary diarrhea in both groups were given montmorillonite powder orally. Time of occurrence, incidence of diarrhea, the number of diarrhea three days after onset, diarrhea duration and adverse reactions in the course of treatment of both groups were statistically analyzed. Results There were 33 cases of diarrhea in the control group, with the incidence rate of 56.9%; in the observation group there were 12 cases of diarrhea, with the incidence rate of 19.4%. Differences analysis results between the two groups were statistically significant (x2 = 11.87, P < 0.01). Diarrhea onset times, number of diarrhea three days after onset and diarrhea duration of the two groups were significantly different (P < 0.01 or P < 0.05). In addition to antibiotics allergic reactions in both groups, the control group showed four cases of fungal stomatitis. No other significant adverse reactions occurred. Conclusion Brad's yeast used in the prevention of secondary diarrhea in neonatal infectious pneumonia shows good effect. It can significantly reduce and delay the occurrence of secondary diarrhea, reduce the secondary diarrhea extent, lead to rapid recovery after symptomatic treatment of diarrhea. It is safe to be used in the prevention of neonatal antibiotic-associated diarrhea except for critically ill cases.%目的 观察布拉酵母菌用于预防新生儿感染性肺炎继发腹泻的临床效果及安全性.方法 将符合新生儿感染性肺炎诊断的患儿120例分为观察组(62

    The clinical effects of Nifuroxasid (N), Trimetoprim sulphametoxasol (TS) and Bactisubtil (B) on bacillar dysentery and alimentary toxicoinfections in the patients treated at the Clinic from January 1984 to the end of December 1989 have been analysed. According to the clinical signs, patients have been divided in ten categories of light, mild and heavy forms. In total, 329 cases of bacillar dysentery and 89 cases of alimentary toxicoinfections have been analysed. The following was established: A. Bacilar dysentery: the fastest normalization of the stool was achieved with N in every clinical form (averages 2.2, 3.5 and 4.05 days). With TS the effects were slower (3.0, 3.9 and 4.4 days), but the slowest normalization was recorded with B (3.4, 4.6 and 5.4 days). However, with TS, some Shigella strains showed resistance (in 23 out of 94 antibiograms), which diminished the effects. B. Alimentary toxicoinfections were treated only with N and B, since these forms of diarrhea caused by toxigenic factors were milder. Better results were achieved with N in this case as well.

    Full Text Available We investigated the effect of a mixture of long-chain fructo-oligosaccharides, galacto-oligosaccharides and acidic oligosaccharides on the number and consistency of stools and on immune system biomarkers in 104 supplemented and non-supplemented subjects (aged 9–24 months with acute diarrhea. Interleukin-1 (IL-1, IL-1RA, IL-6, IL-8, IL-10, TNF-α and sIL-2R cytokine levels were determined. The significant decrease in number of stools and increase in stool consistency in the supplemented group was of little clinical relevance. The only significant change in pro- and anti-inflammatory cytokines was decreased TNF-α levels in the supplemented group. Prebiotic supplementation during acute diarrhea episodes did not influence the clinical course.

    The levels of neutralizing antibody to a pathogen are an effective indicator to predict efficacy of a vaccine in trial. And yet not all the trial vaccines are in line with the theory. Using dengue virus (DENV) to investigate the viral morphology affecting the predictive value, we evaluated the viral morphology in acute dengue plasma compared to that of Vero cells derived DENV. The virions in plasma were infectious and heterogeneous in shape with a "sunny-side up egg" appearance, viral RNA was enclosed with CD61+ cell-derived membrane interspersed by the viral envelope protein, defined as dengue vesicles. The unique viral features were also observed from ex vivo infected human bone marrow. Dengue vesicles were less efficiently neutralized by convalescent patient serum, compared to virions produced from Vero cells. Our results exhibit a reason why potencies of protective immunity fail in vivo and significantly impact dengue vaccine and drug development.

    Full Text Available Abstract Background A high dose of anti-infective agents is recommended when treating infectious meningitis. High creatinine clearance (CrCl may affect the pharmacokinetic / pharmacodynamic relationships of anti-infective drugs eliminated by the kidneys. We recorded the incidence of high CrCl in intensive care unit (ICU patients admitted with meningitis and assessed the diagnostic accuracy of two common methods used to identify high CrCl. Methods Observational study performed in consecutive patients admitted with community-acquired acute infectious meningitis (defined by >7 white blood cells/mm3 in cerebral spinal fluid between January 2006 and December 2009 to one medical ICU. During the first 7 days following ICU admission, CrCl was measured from 24-hr urine samples (24-hr-UV/P creatinine and estimated according to Cockcroft-Gault formula and the simplified Modification of Diet in Renal Disease (MDRD equation. High CrCl was defined as CrCl >140 ml/min/1.73 m2 by 24-hr-UV/P creatinine. Diagnostic accuracy was performed with ROC curves analysis. Results Thirty two patients were included. High CrCl was present in 8 patients (25% on ICU admission and in 15 patients (47% during the first 7 ICU days for a median duration of 3 (1-4 days. For the Cockcroft-Gault formula, the best threshold to predict high CrCl was 101 ml/min/1.73 m2 (sensitivity: 0.96, specificity: 0.75, AUC = 0.90 ± 0.03 with a negative likelihood ratio of 0.06. For the simplified MDRD equation, the best threshold to predict high CrCl was 108 ml/min/1.73 m2 (sensitivity: 0.91, specificity: 0.80, AUC = 0.88 ± 0.03 with a negative likelihood ratio of 0.11. There was no difference between the estimated methods in the diagnostic accuracy of identifying high CrCl (p = 0.30. Conclusions High CrCl is frequently observed in ICU patients admitted with community-acquired acute infectious meningitis. The estimated methods of CrCl could be used as a screening tool to

    Chronic diarrhea is usually associated with a number of non-infectious causes. When definitive treatment is unavailable, symptomatic drug therapy is indicated. Pharmacologic agents for chronic diarrhea include loperamide, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists, diosmectite, cholestyramine, probiotics, antispasmodics, rifaximin, and anti-inflammatory agents. Loperamide, a synthetic opiate agonist, decreases peristaltic activity and inhibits secretion, resulting in the reduction of fluid and electrolyte loss and an increase in stool consistency. Cholestyramine is a bile acid sequestrant that is generally considered as the first-line treatment for bile acid diarrhea. 5-HT3 receptor antagonists have significant benefits in patients with irritable bowel syndrome (IBS) with diarrhea. Ramosetron improves stool consistency as well as global IBS symptoms. Probiotics may have a role in the prevention of antibiotic-associated diarrhea. However, data on the role of probiotics in the treatment of chronic diarrhea are lacking. Diosmectite, an absorbent, can be used for the treatment of chronic functional diarrhea, radiation-induced diarrhea, and chemotherapy-induced diarrhea. Antispasmodics including alverine citrate, mebeverine, otilonium bromide, and pinaverium bromide are used for relieving diarrheal symptoms and abdominal pain. Rifaximin can be effective for chronic diarrhea associated with IBS and small intestinal bacterial overgrowth. Budesonide is effective in both lymphocytic colitis and collagenous colitis. The efficacy of mesalazine in microscopic colitis is weak or remains uncertain. Considering their mechanisms of action, these agents should be prescribed properly.

    Full Text Available Acute post-infectious glomerulonephritis (APIGN is uncommonly seen in adults; its incidence is progressively declining, particularly in developed countries. The aim of this study was to evaluate the epidemiological, clinical and biologic features of APIGN in a Tunisian center. A retrospective descriptive analytic study was carried out on 50 patients aged more than 15 years who were admitted to the Monastir Hospital between 1991 and 2007, with a diagnosis of APIGN. There were more males than females (66% vs. 34%, and the mean age of the patients was 36.8 ± 10 years. Only 10% had an immunocompromised background, including diabetes. The most common site of infection was upper respiratory tract, followed by skin and pneumonia. The most common causative agent was Streptococcus (66%, followed by Staphylococcus (12%. 73.8% of the patients had low C3 complement levels. The mean peak serum creatinine was 190 μmol, and 4% of patients required acute dialysis. The patients were followed-up for a mean period of 18 months (range, 0.16-97 months. During follow-up, of the 46 patients reviewed in the consultation, the majority showed complete remission, 12 patients had persisting abnormalities such as hypertension in 17%, chronic renal failure in 8% and proteinuria in 6.5%, and one patient had concomitant hypertension and chronic renal failure. Our study suggests that APIGN is still endemic in some parts of the world such as Tunisia, and our data showed a favorable prognosis in adults.

    Full Text Available Prolonged diarrhea is usually defined as acute-onset diarrhea lasting 7 days or more, but less than 14 days. Its trend has been declining in recent years because of improvement in the management of acute diarrhea, which represents the ideal strategy to prevent prolonged diarrhea. The pathogenesis of prolonged diarrhea is multifactorial and essentially based on persistent mucosal damage due to specific infections or sequential infections with different pathogens, host-related factors including micronutrient and/or vitamin deficiency, undernutrition and immunodeficiency, high mucosal permeability due to previous infectious processes and nutrient deficiency with consequential malabsorption, and microbiota disruption. Infections seem to play a major role in causing prolonged diarrhea in both developing and developed areas. However, single etiologic pathogens have not been identified, and the pattern of agents varies according to settings, host risk factors, and previous use of antibiotics and other drugs. The management of prolonged diarrhea is complex. Because of the wide etiologic spectrum, diagnostic algorithms should take into consideration the age of the patient, clinical and epidemiological factors, and the nutritional status and should always include a search for enteric pathogens. Often, expensive laboratory evaluations are of little benefit in guiding therapy, and an empirical approach may be effective in the majority of cases. The presence or absence of weight loss is crucial for driving the initial management of prolonged diarrhea. If there is no weight loss, generally there is no need for further evaluation. If weight loss is present, empiric anti-infectious therapy or elimination diet may be considered once specific etiologies have been excluded.

  7. Absence of intestinal PPARγ aggravates acute infectious colitis in mice through a lipocalin-2-dependent pathway.

    Directory of Open Access Journals (Sweden)

    Parag Kundu

    2014-01-01

    Full Text Available To be able to colonize its host, invading Salmonella enterica serovar Typhimurium must disrupt and severely affect host-microbiome homeostasis. Here we report that S. Typhimurium induces acute infectious colitis by inhibiting peroxisome proliferator-activated receptor gamma (PPARγ expression in intestinal epithelial cells. Interestingly, this PPARγ down-regulation by S. Typhimurium is independent of TLR-4 signaling but triggers a marked elevation of host innate immune response genes, including that encoding the antimicrobial peptide lipocalin-2 (Lcn2. Accumulation of Lcn2 stabilizes the metalloproteinase MMP-9 via extracellular binding, which further aggravates the colitis. Remarkably, when exposed to S. Typhimurium, Lcn2-null mice exhibited a drastic reduction of the colitis and remained protected even at later stages of infection. Our data suggest a mechanism in which S. Typhimurium hijacks the control of host immune response genes such as those encoding PPARγ and Lcn2 to acquire residence in a host, which by evolution has established a symbiotic relation with its microbiome community to prevent pathogen invasion.

  11. Acute and subacute non-infectious lung diseases. Usefulness of HRCT for evaluation of activity especially in follow-up

    International Nuclear Information System (INIS)

    The purpose of this study was to survey the usefulness of high-resolution CT (HRCT) for the evaluation of activity in acute and subacute non-infectious diffuse infiltrative lung diseases before and after corticosteroid treatment. Sequential HRCT images and chest radiographs obtained before and after treatment were retrospectively evaluated in 33 patients with acute or subacute non-infectious diffuse infiltrative lung diseases. All these patients were histologically confirmed to have pulmonary Inflammation and to have responded to treatment with corticosteroid. Radiographic and CT scores were correlated with the degree of dyspnea and the results of arterial blood gas analysis using Spearman's rank-correlation coefficient. On follow-up HRCT, the profusion score of areas with increased attenuation was significantly correlated with arterial oxygen tension (PaO2) (p=.003, r=-.53) and the alveolar-arterial oxygen tension difference (AaDO2) (p=.001, r=.57). No other correlation was found after treatment. Nodular and linear opacities were more commonly seen on follow-up chest radiographs and HRCT images than on initial ones. HRCT is useful for the evaluation of disease activity in acute and subacute non-infectious infiltrative lung diseases before and after treatment if paying special attention to the profusion of ground-glass attenuation. Even if pretreatment HRCT has not been performed, posttreatment HRCT should be examined. (author)

    Full Text Available Abstract Background Campylobacter jejuni is a major cause of gastroenteritis worldwide. In Thailand, several strains of C. jejuni have been isolated and identified as major diarrheal pathogens among adult travelers. To study the epidemiology of C. jejuni in adult travelers and U.S. military personnel with acute diarrhea in Thailand from 1998-2003, strains of C. jejuni were isolated and phenotypically identified, serotyped, tested for antimicrobial susceptibility, and characterized using pulsed-field gel electrophoresis (PFGE. Results A total of 312 C. jejuni isolates were obtained from travelers (n = 46 and U.S. military personnel (n = 266 in Thailand who were experiencing acute diarrhea. Nalidixic acid and ciprofloxacin resistance was observed in 94.9% and 93.0% of the isolates, respectively. From 2001-2003, resistance to tetracycline (81.9%, trimethoprim-sulfamethoxazole (57.9%, ampicillin (28.9%, kanamycin (5.9%, sulfisoxazole (3.9%, neomycin (2.0%, and streptomycin (0.7% was observed. Combined PFGE analysis showed considerable genetic diversity among the C. jejuni isolates; however, four PFGE clusters included isolates from the major Lior serotypes (HL: 36, HL: 11, HL: 5, and HL: 28. The PFGE analysis linked individual C. jejuni clones that were obtained at U.S. military exercises with specific antimicrobial resistance patterns. Conclusions In summary, most human C. jejuni isolates from Thailand were multi-resistant to quinolones and tetracycline. PFGE detected spatial and temporal C. jejuni clonality responsible for the common sources of Campylobacter gastroenteritis.

    Full Text Available Abstract In order to assess the effects of juice feedings during acute diarrhea a double-blind, randomized study was performed in 90 children, mean age of 10 ± 4.28 months. Thirty patients with acute diarrhea were fed twice-daily 15 ml/kg of Apple Juice (AJ, 30 received White Grape Juice (WGJ, and 30 were given colored and flavored water (WA as part of their age appropriate dietary intake. The duration and severity of diarrhea were the main endpoint variables of the study performed in a metabolic unit. The patients were similar among the 3 groups, had diarrhea for 50–64 hours prior to admission, and were dehydrated when admitted to the unit for study. Half of the patients in each group were well nourished and the others had mild to moderate degrees of malnutrition. Rotavirus infection was the agent causing the illness in 63% of the patients. The infants fed juice ingested 14–17% more calories than those given WA, (those receiving AJ and WGJ ingested 95 and 98 Calories/Kg/d respectively whereas those receiving WA consumed 81 cal/kg/d. The increased energy intake was not at the expense of other foods or milk formula. The mean body weight gain was greater among patients receiving WGJ (+ 50.7 gm as compared with the patients in the AJ group (+ 18.3 gm or the patients fed WA (- 0.7 gm (p = 0.08. The duration of the illness was longer in the infants fed juice as compared with those given WA (p = 0.006, the mean +/- SD duration in hours was 49.4 ± 32.6, 47.5 ± 38.9 and 26.5 ± 27.4 in patients fed AJ, WGJ and WA respectively. All patients improved while ingesting juice and none of them developed persistent diarrhea; most recovered within 50 hours of the beginning of treatment and less than one fourth had diarrhea longer than 96 hours in the unit. The fecal losses were also increased among the juice fed patients (p = 0.001; the mean ± SD fecal excretion in g/kg/h was 3.94 ± 2.35, 3.59 ± 2.35, and 2.19 ± 1.63 in AJ, WGJ and WA respectively

    Full Text Available Context: Acute pancreatitis has occasionally been reported in association with Campylobacter jejuni infection in humans. However, the mechanism linking Campylobacter jejuni infection and pancreatitis isunclear. Acute pancreatitis in association with an infectious illness may be related to underlying genetic mutations. For instance, studies show that mutations in the cystic fibrosis transmembrane conductance regulator gene increase the susceptibility for acute and chronic pancreatitis. Case report :We describe a patient with Campylobacter jejuni infection who developed acute pancreatitis in the setting of an underlying cystic fibrosis transmembrane conductance regulator gene mutation. Discussion :In this patient with an underlying mutation in the CFTR gene, we propose that the interaction between the mutant gene and an environmental factor, Campylobacter jejuni infection, resulted in pancreatitis.

    Full Text Available Introduction: Acute kidney injury (AKI is a frequent and potentially fatal complication in infectious diseases. The aim of this study was to investigate the clinical aspects of AKI associated with infectious diseases and the factors associated with mortality. Methods: This retrospective study was conducted in patients with AKI who were admitted to the intensive care unit (ICU of a tertiary infectious diseases hospital from January 2003 to January 2012. The major underlying diseases and clinical and laboratory findings were evaluated. Results: A total of 253 cases were included. The mean age was 46±16 years, and 72% of the patients were male. The main diseases were human immunodeficiency virus (HIV infection, HIV/acquired immunodeficiency syndrome (AIDS (30%, tuberculosis (12%, leptospirosis (11% and dengue (4%. Dialysis was performed in 70 cases (27.6%. The patients were classified as risk (4.4%, injury (63.6% or failure (32%. The time between AKI diagnosis and dialysis was 3.6±4.7 days. Oliguria was observed in 112 cases (45.7%. The Acute Physiology and Chronic Health Evaluation (APACHE II scores were higher in patients with HIV/AIDS (57±20, p-value=0.01 and dengue (68±11, p-value=0.01. Death occurred in 159 cases (62.8%. Mortality was higher in patients with HIV/AIDS (76.6%, p-value=0.02. A multivariate analysis identified the following independent risk factors for death: oliguria, metabolic acidosis, sepsis, hypovolemia, the need for vasoactive drugs, the need for mechanical ventilation and the APACHE II score. Conclusions: AKI is a common complication in infectious diseases, with high mortality. Mortality was higher in patients with HIV/AIDS, most likely due to the severity of immunosuppression and opportunistic diseases.

    Full Text Available Abstract Background Bovine viral diarrhea virus (BVDV strains circulating in livestock herds show significant sequence variation. Conventional wisdom states that most sequence variation arises during acute infections in response to immune or other environmental pressures. A recent study showed that more nucleotide changes were introduced into the BVDV genomic RNA during the establishment of a single fetal persistent infection than following a series of acute infections of naïve cattle. However, it was not known if nucleotide changes were introduce when the virus crossed the placenta and infected the fetus or during the acute infection of the dam. Methods The sequence of the open reading frame (ORF from viruses isolated from four acutely infected pregnant heifers following exposure to persistently infected (PI calves was compared to the sequences of the virus from the progenitor PI calf and the virus from the resulting progeny PI calf to determine when genetic change was introduced. This was compared to genetic change found in viruses isolated from a pregnant PI cow and its PI calf, and in three viruses isolated from acutely infected, non-pregnant cattle exposed to PI calves. Results Most genetic changes previously identified between the progenitor and progeny PI viruses were in place in the acute phase viruses isolated from the dams six days post-exposure to the progenitor PI calf. Additionally, each progeny PI virus had two to three unique nucleotide substitutions that were introduced in crossing the placenta and infection of the fetus. The nucleotide sequence of two acute phase viruses isolated from steers exposed to PI calves revealed that six and seven nucleotide changes were introduced during the acute infection. The sequence of the BVDV-2 virus isolated from an acute infection of a PI calf (BVDV-1a co-housed with a BVDV-2 PI calf had ten nucleotides that were different from the progenitor PI virus. Finally, twenty nucleotide changes were

    A cross-sectional study was undertaken during 2012-2013 to determine the prevalence, strains and factors associated with rotavirus infection among under-5-year-old children hospitalized with acute diarrhea in Uganda. Rotaviruses were detected in 37 % (263/712) of the children. The most prevalent strains were G9P[8] (27 %, 55/204) and G12P[4] (18.6 %, 38/204). Mixed infections were detected in 22.5 % (46/204) of the children. The study suggests that consumption of raw vegetables (OR = 1.45, 95 % CI = 1.03-2.03) and family ownership of dogs (OR = 1.9, 95 % CI = 1.04-3.75) increases the risk of rotavirus infection. The study findings will be used to assess the impact of RV vaccination in Uganda. PMID:26724820

    Jia Liu

    Full Text Available Acute respiratory tract infections (ARTIs are associated with significant morbidity and mortality worldwide, especially in children under the age of 5 years. Almost 2 million children die from ARTIs each year, and most of them are from developing countries. The prevalence and correlation of pathogens in ARTIs are poorly understood, but are critical for improving case prevention, treatment, and management. In this study, we investigated the prevalence and correlation of infectious agents in children with ARTIs. A total of 39,756 children with one or more symptoms, including fever, cough, sore throat, tonsillitis, pharyngitis, herpangina, pneumonia, and bronchiolitis, were enrolled in the study. All patients were hospitalized in Wuhan Children's Hospital between October 1, 2010 and September 30, 2012, and were evaluated for infectious agents. Pathogens, including Mycoplasma pneumoniae, influenza A virus, influenza B virus, adenoviruses, respiratory syncytial virus, parainfluenza virus, Legionella pneumophila, Chlamydophila pneumoniae, and Coxiella burnetii, were screened simultaneously in patient blood samples using anti-pathogen IgM tests. Regression analysis was used to reveal correlations among the pathogens. Our results showed that one or more pathogens were identified in 10,206 patients, and that Mycoplasma pneumoniae, adenoviruses, and influenza B virus were the leading infectious agents. Mixed-infections of pathogens were detected in 2,391 cases, with Mycoplasma pneumoniae as the most frequent pathogen. The most common agents in the co-infections were Mycoplasma pneumoniae and influenza B virus. Regression analysis revealed a linear correlation between the proportion of mixed infections and the incidence of multi-pathogen infections. The prevalence of infectious agents in children with ARTIs was determined. Equations were established to estimate multiple infections by single-pathogen detection. This revealed a linear correlation for

    Aortitis is broadly divided into infectious and non-infectious etiologies, each with distinct treatment implications. We present the case of a patient who sustained a type A aortic dissection during urgent coronary angiography for acute coronary syndrome. Clinical findings and events during the procedure raised suspicion for an underlying vascular disorder; however, the diagnosis of staphylococcal aortitis was not made until pathological examination of resected tissue. Clues to the diagnosis of infectious aortitis noted throughout the patient's clinical course are detailed as are potential consequences of diagnostic delays and treatment decisions, underscoring the difficulties in recognizing and managing the condition. In addition, we describe a previously unreported complication of cardiac catheterization in the setting of an infectious aortopathy.

  13. Pathological studies on bovine viral diarrhea

    International Nuclear Information System (INIS)

    Bovine viral diarrhea virus (BVDV) is classified as an RNA virus in the family flavin viride and is a member of the genus pest virus (Collet et al 1989). BVDV has a worldwide distribution and infections in cattle populations (Kahrs et al 1970). It was recognized since 50 years ago, the initial description of an acute enteric disease of cattle in North America, which was characterized by outbreaks of diarrhea and erosive of digestive tract (Olafsonp et al 1946). The disease and causative agent were named bovine viral diarrhea (B V D ) and (B V DV), respectively. This virus was subsequently associated with a sporadically occurring and highly fatal enteric disease that was termed mucosal disease (M D), (Ramsey and Chivers 1953). The initial isolate of BVDV did not produce cytopathic effect in cell culture, whereas an isolate from MD did produce cytopathic effects (Lee et al 1957). In vitro characteristic of non cytopathic or sytopathic effects of BVDV is referred to as the biotype of the virus. It has now been established that MD occurs only when xattle that are born immuno tolerant to and persistently infected with a noncyropathic BVDV become super infected with a cytopathic BVDV. The knowledge of the molecular biology. Pathogenesis and epidemiology of BVDV has greatly evolved in the past 10-15 years and has provided a better understanding of this complex infectious agent. Infection with BVDV can result in a wide spectrum of diseases ranging from subclinical infection s to a highly fatal from known as mucosal disease (ND). The clinical response to infection depends on multiple interactive factors. Host factors that influence the clinical outcome of BVDV infection include whether the host is immunocompetent or immuno tolerant to BVDV, pregnancy status, gestational age of the fetus, immune status (passively derived or actively derived from previous infection or vaccination) and concurrent level of environmental stress

    Full Text Available Probiotic bacteria have beneficial effects in prevention and treatment of different diseases. The results of preventive and therapeutic effect of probiotic bacteria on diarrhea during last ten years are shown in this paper. The greatest preventive and therapeutic effect of probiotic bacteria was identified for acute diarrhea in children caused by rotaviruses. Significant, but slightly lower effect of probiotic bacteria was proved for antibiotic associated diarrhea. Positive effect in prevention of traveller’s diarrhea and radiation-induced diarrhea is not significant. Preventive and therapeutic effect on diarrhea is not dependent on the way of probiotic bacteria consumption, by fermented milk, capsule or oral rehydration solution.

    To address the organizational complexities associated with a highly virulent infectious disease (HVID) hazard, such as Ebola Virus Disease (EVD), an acute care facility should institute an emergency management program rooted in the fundamentals of mitigation, preparedness, response, and recovery. This program must address all known facets of the care of a patient with HVID, from unannounced arrival to discharge. The implementation of such a program not only serves to mitigate the risks from an unrecognized exposure but also serves to prepare the organization and its staff to provide for a safe response, and ensure a full recovery. Much of this program is based on education, training, and infection control measures along with resourcing for appropriate personal protective equipment which is instrumental in ensuring an organized and safe response of the acute care facility in the service to the community. This emergency management program approach can serve as a model in the care of not only current HVIDs such as EVD but also future presentations in our healthcare setting. PMID:26963227

    Full Text Available In this review we report our recent findings of histopathological features of plaque instability and the association with Mycoplasma pneumoniae (MP and Chlamydia pneumoniae (CP infection, studying thrombosed coronary artery segments (CAS of patients who died due to acute myocardial infarction. Vulnerable plaques are known to be associated with fat atheromas and inflammation of the plaque. Here we demonstrated that vulnerability is also related with focal positive vessel remodeling that maintains relatively well preserved lumen even in the presence of large atheromatous plaques. This phenomena may explain why the cinecoronariography may not detect large and dangerous vulnerable plaques. Greater amount of these bacteria in vulnerable plaques is associated with adventitial inflammation and positive vessel remodeling: the mean numbers of lymphocytes were significantly higher in adventitia than in the plaque, good direct correlation was obtained between numbers of CD20 B cells and numbers of CP infected cells in adventitia, and between % area of MP-DNA in the plaque and cross sectional area of the vessel, suggesting a cause-effect relationship. Mycoplasma is a bacterium that needs cholesterol for proliferation and may increase virulence of other infectious agents. In conclusion, co-infection by Mycoplasma pneumoniae and Chlamydia pneumoniae may represent an important co-factor for plaque instability, leading to coronary plaque thrombosis and acute myocardial infarction, since larger amount of these bacteria strongly correlated with histological signs of more vulnerability of the plaque. The search of CMV and Helicobacter pilori in these tissues resulted negative.

  19. The evolution of bovine viral diarrhea: a review

    2002-01-01

    The economic importance of bovine viral diarrhea is increasing with the emergence of seemingly more virulent viruses, as evidenced by outbreaks of hemorrhagic syndrome and severe acute bovine viral diarrhea beginning in the 1980s and 1990s. It appears that evolutionary changes in bovine viral diarrhea virus were responsible for these outbreaks. The genetic properties of the classical bovine viral diarrhea virus that contribute to the basis of current diagnostic tests, vaccines, and our unders...

    The relationship between pharyngeal infections, such as tonsillitis and pharyngitis, caused by group A beta-hemolytic streptococci (BHSA) and acute rheumatic fever (ARF) is a well-established fact confirmed by numerous studies carried out along the following lines: epidemiological, immunological, therapeutic, and prophylactic. The currently available data provide an opportunity to discuss the existence of «rheumatogenic» BHSA strains exhibiting a number of characteristic clinical and morphological properties. According to the current recommendations penicillins remain the means of first-line therapy for the treatment of acute forms of BHSA-induced tonsillitis and pharyngitis, whereas the macrolides should be applied only as the alternative medications in the patients with intolerance to beta-lactam antibiotics. This article contains characteristics of BHSA-carrier state and the principal indications for the prescription of antibiotics to the patients with these conditions. The key principle of secondary medicamental prophylaxis of acute respiratory infections are expounded along with the main fines of future research on the problems associated with BHSA-induced pharyngeal infections.

    Child day-care attendance is considered to be an acute early childhood disease risk factor, the studies available however not affording the possibility of fully quantifying this risk. A systematic review of clinical trials and cohort studies was conducted, in which the effects child day-care attendance had on the health of young children based on the Cochrane Collaboration, PubMed and Spanish Medical Index databases, without any time or language-related limits, were analyzed and rounded out with analyses of referenced works and an additional EMBASE search. The methodological quality was evaluated by means of personalized criteria. Pooling measures (relative risks, incidence density ratios and weighted mean differences) were calculated with their confidence intervals, assuming random effects models. A significant increase was found to exist of a risk consistent over time and among different social and geographical environments. Considering the most methodologically-stringent studies with adjusted effect estimates, child day-care attendance was related to an increased risk of upper respiratory tract infection (RR=1,88), acute otitis media (RR=1,58), otitis media with fluid draining (RR=2,43), lower respiratory tract infections (overall RR=210; acute pneumonia RR=1.70; broncholitis RR=1,80; bronchitis RR=2,10) and gastroenteritis (RR=1,40). Child day-care attendance could be responsible for 33%-50% of the episodes of respiratory infection and gastroenteritis among the exposed population. In conclusion, it can be said that the risk for childhood health attributable to the child day-care attendance is discreet but of high-impact. This information has some major implications for research, clinical practice, healthcare authorities and society as a whole.

    Full Text Available INTRODUCTION:In Venezuela, acute diarrheic syndrome (ADS is a primary cause of morbi-mortality, often involving the Salmonella genus. Salmonella infections are associated with acute gastroenteritis, one of the most common alimentary intoxications, and caused by the consumption of contaminated water and food, especially meat. METHODS: Conventional and molecular methods were used to detect Salmonella strains from 330 fecal samples from individuals of different ages and both sexes with ADS. Polymerase chain reaction (PCR was used for the molecular characterization of Salmonella, using invA, sefA, and fliC genes for the identification of this genus and the serotypes Enteritidis and Typhimurium, respectively. RESULTS: The highest frequency of individuals with ADS was found in children 0-2 years old (39.4%, and the overall frequency of positive coprocultures was 76.9%. A total of 14 (4.2% strains were biochemically and immunologically identified as Salmonella enterica subsp. enterica, of which 7 were classified as belonging to the Enteritidis serotype, 4 to the Typhimurium serotype, and 3 to other serotypes. The S. enterica strains were distributed more frequently in the age groups 3-4 and 9-10 years old. CONCLUSIONS: The molecular characterization method used proved to be highly specific for the typing of S. enterica strains using DNA extracted from both the isolated colonies and selective enrichment broths directly inoculated with fecal samples, thus representing a complementary tool for the detection and identification of ADS-causing bacteria.

    A 25-year-old Japanese man was admitted with general malaise and fever, which had developed 12 days after coming back to Japan from Indonesia. Blood examination revealed elevated transaminase levels and positivity for the IgM anti-HAV antibody; therefore, he was diagnosed with acute hepatitis A. HAV-RNA was detected in his serum and phylogenetically classified as subgenotype IA. The partial genome in the VP1/P2A region was consistent with the strain recently isolated from Surabaya, which indicated that he had been infected during his stay in Indonesia. Thus, HAV vaccination is recommended before visiting HAV-endemic countries for a long period of time.

    Objective To study acute diarrhea status and risk factors of dietary behavior in Shanghai. Methods A stratified multi-stage cluster random household sampling was used in this cross-sectional survey. Results The incidence rate of acute diarrhea among Shanghai residents was 0. 68 episodes per person-year. It was 0. 75 episodes per person-year for males and 0.62 episodes per person-year for females. It was estimated to be 0.96, 0.54, 0.71, 0.71 and 0.64 episodes per person-year for age groups of 0 - 7 , 8 - 17 , 18 - 33 , 34 - 59 and ≥60, respectively. 24. 34% of respondents suspected their illness was due to contaminated food. 40. 03% of respondents had visited doctor. Single variable and logistic regression analysis showed that odds ratio of acute diarrhea were 1.37 ( 95 % confidence interval, 1. 13 - 1. 67 ) , 0.66 (95% confidence interval, 0.49 -0.88) and 0.76 (95% confidence interval, 0.62 -0.94) for the respondents who had the behavior of eating delicatessen, keeping food at low temperature and salty taste. Conclusion Acute diarrhea is a common illness among residents in Shanghai. The incidence of acute diarrhea was slightly higher in males. After the age of eight, the incidence declined, but increased again in adult and then declined above 60. The behavior of eating delicatessen was a risk factor for acute diarrhea. The habit of keeping the food at low temperature and salty taste might be the protective factors for acute diarrhea.%目的 了解上海市急性腹泻现况及饮食行为危险因素.方法 采用多阶段随机抽样,进行横断面入户问卷调查.结果 上海市居民急性腹泻年发生率0.68次/人年.男性0.75次/人年、女性0.62次/人年,0~7岁、8 ~17岁、18 ~33岁、34 ~59岁、≥60岁分别为0.96、0.54、0.71、0.71、0.64次/人年.有24.34%人自诉有可疑食物史、40.03%的人就诊.单因素及Logistic回归多因素分析显示:食用散装熟食者的急性腹泻OR值为1.37、95%CI (1.13~1.67),

    Objectives To assess the magnitude of difference in antibiotic use between clinical teams in the acute setting and assess evidence for any adverse consequences to patient safety or healthcare delivery. Design Prospective cohort study (1 week) and analysis of linked electronic health records (3 years). Setting UK tertiary care centre. Participants All patients admitted sequentially to the acute medical service under an infectious diseases acute physician (IDP) and other medical teams during 1 week in 2013 (n=297), and 3 years 2012–2014 (n=47 585). Primary outcome measure Antibiotic use in days of therapy (DOT): raw group metrics and regression analysis adjusted for case mix. Secondary outcome measures 30-day all-cause mortality, treatment failure and length of stay. Results Antibiotic use was 173 vs 282 DOT/100 admissions in the IDP versus non-IDP group. Using case mix-adjusted zero-inflated Poisson regression, IDP patients were significantly less likely to receive an antibiotic (adjusted OR=0.25 (95% CI 0.07 to 0.84), p=0.03) and received shorter courses (adjusted rate ratio (RR)=0.71 (95% CI 0.54 to 0.93), p=0.01). Clinically stable IDP patients of uncertain diagnosis were more likely to have antibiotics held (87% vs 55%; p=0.02). There was no significant difference in treatment failure or mortality (adjusted p>0.5; also in the 3-year data set), but IDP patients were more likely to be admitted overnight (adjusted OR=3.53 (95% CI 1.24 to 10.03), p=0.03) and have longer length of stay (adjusted RR=1.19 (95% CI 1.05 to 1.36), p=0.007). Conclusions The IDP-led group used 30% less antibiotic therapy with no adverse clinical outcome, suggesting antibiotic use can be reduced safely in the acute setting. This may be achieved in part by holding antibiotics and admitting the patient for observation rather than prescribing, which has implications for costs and hospital occupancy. More information is needed to indicate whether any such longer admission will

    To be able to colonize its host, invading Salmonella enterica serovar Typhimurium must disrupt and severely affect host-microbiome homeostasis. Here we report that S. Typhimurium induces acute infectious colitis by inhibiting peroxisome proliferator-activated receptor gamma (PPARγ) expression in intestinal epithelial cells. Interestingly, this PPARγ down-regulation by S. Typhimurium is independent of TLR-4 signaling but triggers a marked elevation of host innate immune response genes, including that encoding the antimicrobial peptide lipocalin-2 (Lcn2). Accumulation of Lcn2 stabilizes the metalloproteinase MMP-9 via extracellular binding, which further aggravates the colitis. Remarkably, when exposed to S. Typhimurium, Lcn2-null mice exhibited a drastic reduction of the colitis and remained protected even at later stages of infection. Our data suggest a mechanism in which S. Typhimurium hijacks the control of host immune response genes such as those encoding PPARγ and Lcn2 to acquire residence in a host, which by evolution has established a symbiotic relation with its microbiome community to prevent pathogen invasion.

  9. Radiological Findings in Children with Acute Pneumonia: Age More Important Than Infectious Agent

    International Nuclear Information System (INIS)

    Purpose: To evaluate whether radiological findings and healing time in children with pneumonia are correlated to etiologic agent. Material and Methods: A total of 346 children with radiologically verified acute pneumonia, and with accomplished serological tests for bacteria and viruses, were included in the study. Five etiological groups were analysed: children with bacterial etiology only, with viral etiology only, with mixed bacterial and viral etiology, with Mycoplasma only, and children with no etiology. Results: The chest films of each etiological group were analysed and the findings were correlated to the children's age. The radiological findings did not differ between the etiological groups. Radiological findings correlated significantly with the patient's age. The radiological healing frequency at check-up X-ray was found to be significantly lower in children with mixed bacterial and viral etiology compared to children in each of the other groups and to the material as a whole. Conclusion: Conclusions about the etiology could not be drawn from the chest X-ray findings

    Full Text Available Introduction: Acute infectious diarrhea is still regarded as a public health problem associated with a wide range of etiologic agents, from which Salmonella enterica is particularly worth mentioning inasmuch as it is a major cause of inflammatory diarrhea in both developed and developing countries. Objective: To assess the distribution of S. enterica among children with acute diarrhea in Belo Horizonte and to characterize bacterium isolates. Material and methods: The study group comprised a total of 157 children from low socioeconomic background. Stool samples were collected for leukocyte analysis and Salmonella bacterial culture. The isolates were serotyped and evaluated as to antimicrobial susceptibility profile, extended-spectrum β-lactamases (ESBL production, and presence of virulence markers (invA, iroB, and spvC. RESULTS: A total of 5/3.2% children were infected by S. enterica, 3/60% by S. enterica Typhimurium, 1/20% by S. enterica Enteritidis and 1/20% S. enterica subsp. enterica serotype 8.20:z4,z23:-. Fecal leucocytes were detected in two out of five fecal specimens positive for S. enterica. Isolates from three children were resistant to nalidixic acid, nalidixic acid + chloramphenicol, and nalidixic acid + chloramphenicol + ampicillin. ESBL production was not detected. All samples presented invA and iroB genes. spvC marker was observed in isolates from two children infected by S. Typhimurium and S. Enteritidis. Conclusion: The results demonstrate that S. enterica infection is uncommon among children from our region. Furthermore, they indicate the need for periodic monitoring of bacterial antimicrobial susceptibility profile in order to establish suitable antimicrobial therapy when required.INTRODUÇÃO: A diarreia infecciosa aguda é considerada um problema de saúde pública associado a uma ampla gama de agentes etiológicos, entre os quais destaca-se Salmonella enterica, causa importante de diarreia inflamatória em pa

    World Health Organization-recommended rehydration solution for malnourished children (ReSoMal) for rehydrating severe acute malnourished children is not available in India. In present study, 110 consecutive children aged 6-59 months with severely acute malnourishment and acute diarrhea were randomized to low-osmolarity oral rehydration solution (ORS) (osmolarity: 245, sodium: 75) with added potassium (20 mmol/l) or modified ReSoMal (osmolarity: 300, sodium: 45). In all, 15.4% of modified ReSoMal group developed hyponatremia as compared with 1.9% in low-osmolarity ORS, but none developed severe hyponatremia or hypernatremia. Both groups had equal number of successful rehydration (52 each). Both types of ORS were effective in correcting hypokalemia and dehydration, but rehydration was achieved in shorter duration with modified ReSoMal. PMID:26314308

    Full Text Available Acute infectious mononucleosis is a widespread viral disease, which most often manifests in childhood. The development of acute infectious mononucleosis is accompanied by the change of the CD4+/CD8+ T-lymphocytes ratio and the increase of the virus-specific CD8+ cytotoxic T-lymphocytes number. One of the T-lymphocytes number regulation mechanisms is the modulation of their progenitor cells apoptosis. The death receptor CD95 takes part in the regulation of T-lymphocytes apoptosis, including naïve T-cells. We studied the effect of CD95 receptor activation on apoptosis of naïve CD4+ and naïve cytotoxic CD8+ T-lymphocytes in healthy children and children with acute infectious mononucleosis. In this study children with acute infectious mononucleosis at the age of 9 to 16 years were included. For comparison healthy children of the same age with no clinical and laboratory signs of the disease were used. Naïve CD4+ and naïve cytotoxic CD8+ T-lymphocytes were isolated by negative magnetic immunoseparation. The analysis of naïve T-cells apoptosis and the CD95 receptor surface expression density was performed by using the flow cytometry analysis. The analysis of T-cells was performed in three variants: freshly isolated naïve CD4+ T-lymphocytes and naïve cytotoxic CD8+ T-lymphocytes, and also cells after 24 hours of the cultivation with anti-CD95 monoclonal antibodies or without them. In healthy children both CD95– and CD95+ naïve CD4+ T-lymphocytes underwent apoptosis. In children with acute infectious mononucleosis CD95– naïve CD4+ T-lymphocytes lost their susceptibility to apoptosis induction. In healthy children and children with acute infectious mononucleosis CD95– naïve cytotoxic CD8+ T-lymphocytes were resistant to apoptosis in contrast to CD95+ naïve CD4+ T-lymphocytes. In healthy children CD95 receptor did not induce apoptosis of isolated naïve CD4+ T-lymphocytes and naïve cytotoxic CD8+ T-lymphocytes. In children with acute

    ón como el aseguramiento de la provisión de agua potable para el recién nacido.OBJECTIVE: To assess the effect of exclusive breastfeeding and its interactions with selected socioeconomic factors, on the incidence of acute infantile diarrhea during the first three months of life. MATERIAL AND METHODS: A prospective cohort study with a follow up of three months was conducted in 327 mother and child pairs, living in the city of Durango, Mexico, between April and June 1994. Data analyses included simple univariate and bivariate cross-tabulations, as well as multivariate logistic regression models with random effects. RESULTS: Infants who were not exclusively breastfed were at a significantly increased risk of having acute diarrhea during early infancy (ORcombined breastfeeding= 3.23; 95% CI 1.84-5.68 and ORartificial breastfeeding=4.36; 95% CI 2.32-8.19. Moreover, the protective effect of breastfeeding was independent from the effects of the following factors: poor maternal education, lack of social support for baby care, and being an adolescent mother. However, lack of potable water and lack of sewerage were potential effect modifiers of type of lactation deltaG=9.26; p=0.09; ORno water/no sewerage= 2.58; 95% CI 1.10-6.03 in the final multivariate model, for simultaneous lack of potable water and sewerage, which is greater than the sum of the individual OR for each variable. CONCLUSIONS: Similar to previous studies, exclusive breastfeeding was found to have great importance, since this practice protects the child's health and allows for a better development, despite unfavorable social and economic conditions. In particular, it seems that the protection conferred by breastfeeding is stronger when home conditions are poor, but this same condition presents an intervention opportunity, particularly the assurance of potable water provision for the infant when breastfeeding is not an option.

    Full Text Available Aims: To investigate initial Sequential Organ Failure Assessment (SOFA score of patients in Intensive Care Unit (ICU, who were diagnosed with infectious disease, as an indicator of multiple organ dysfunction and to examine if initial SOFA score is a better mortality predictor compared to Simplified Acute Physiology Score (SAPS. Materials and Methods: Hospital-based study done in medical ICU, from June to September 2014 with a sample size of 48. Patients aged 18 years and above, diagnosed with infectious disease were included. Patients with history of chronic illness (renal/hepatic/pulmonary/  cardiovascular, diabetes, hypertension, chronic obstructive pulmonary disease, heart disease, those on immunosuppressive therapy/chemoradiotherapy for malignancy and patients in immunocompromised state were excluded. Blood investigations were obtained. Six organ dysfunctions were assessed using initial SOFA score and graded from 0 to 4. SAPS was calculated as the sum of points assigned to each of the 17 variables (12 physiological, age, type of admission, and three underlying diseases. The outcome measure was survival status at ICU discharge. Results: We categorized infectious diseases into dengue fever, leptospirosis, malaria, respiratory tract infections, and others which included undiagnosed febrile illness, meningitis, urinary tract infection and gastroenteritis. Initial SOFA score was both sensitive and specific; SAPS lacked sensitivity. We found no significant association between age and survival status. Both SAPS and initial SOFA score were found to be statistically significant as mortality predictors. There is significant association of initial SOFA score in analyzing organ dysfunction in infectious diseases (P < 0.001. SAPS showed no statistical significance. There was statistically significant (P = 0.015 percentage of nonsurvivors with moderate and severe dysfunction, based on SOFA score. Nonsurvivors had higher SAPS but was not statistically

    The scope of this study is to perform spatial analysis of integrated environmental and health indicators related to the factors affecting mortality due to diarrhea in children under 1 year of age in Brazilian regions in 2010. Seven environmental indicators, compiled from the IBGE System for Automatic Recovery of the Population Census 2010 database, were formulated. The data with respect to deaths due to diarrhea in children under 1 year of age and live births were obtained from the databases of the Mortality Information Systems and the Live Births Information System of the IT Department of the Unified Health System. The microregions located in the North and Northeast regions revealed 5 and 4 times the rate of mortality in 2009, respectively, due to diarrhea in children under 1 year of age than the Southern Region. Children under 1 year of age living in the microregions located in the North and Northeast are more exposed to risk of death from diarrhea, since the worst figures for the environmental indicators related to poverty and sanitation are concentrated in these locations. In this sense, social, economic, environmental, cultural and health public policies should be based on the principle of equity to address the different local needs of each region. PMID:25272122

    Full Text Available Recent studies have revealed that microbes play an important role in the pathogenesis of gastrointestinal (GI diseases in various animal species, but only limited data is available about the microbiome in cats with GI disease. The aim of this study was to evaluate the fecal microbiome in cats with diarrhea. Fecal samples were obtained from healthy cats (n = 21 and cats with acute (n = 19 or chronic diarrhea (n = 29 and analyzed by sequencing of 16S rRNA genes, and PICRUSt was used to predict the functional gene content of the microbiome. Linear discriminant analysis (LDA effect size (LEfSe revealed significant differences in bacterial groups between healthy cats and cats with diarrhea. The order Burkholderiales, the families Enterobacteriaceae, and the genera Streptococcus and Collinsella were significantly increased in diarrheic cats. In contrast the order Campylobacterales, the family Bacteroidaceae, and the genera Megamonas, Helicobacter, and Roseburia were significantly increased in healthy cats. Phylum Bacteroidetes was significantly decreased in cats with chronic diarrhea (>21 days duration, while the class Erysipelotrichi and the genus Lactobacillus were significantly decreased in cats with acute diarrhea. The observed changes in bacterial groups were accompanied by significant differences in functional gene contents: metabolism of fatty acids, biosynthesis of glycosphingolipids, metabolism of biotin, metabolism of tryptophan, and ascorbate and aldarate metabolism, were all significantly (p<0.001 altered in cats with diarrhea. In conclusion, significant differences in the fecal microbiomes between healthy cats and cats with diarrhea were identified. This dysbiosis was accompanied by changes in bacterial functional gene categories. Future studies are warranted to evaluate if these microbial changes correlate with changes in fecal concentrations of microbial metabolites in cats with diarrhea for the identification of potential diagnostic or

    Objective: To explore the mechanism and type of acute infectious brain edema induced by injection of pertussis bacilli (PB) in rat neocortex, to study the neuroprotective effect of non-competitive antagonist of N-methl-D-aspartate ( NMDA ) receptor ( MK-801 ) and antagonist of Ca2+ channels ( nimodipine )on brain edema, and to investigate the relationship between percentage of water content and cytosolic free calcium concentration ([Ca2+]i) in synaptosomes or content of Evans Blue (EB).Methods: 95 SD rats were randomly divided into five groups, ie, normal control group, sham-operated control group, PB group, nimodipine treatment group and MK-801 pretreatment group. The acute infectious brain edema was induced by injection of PB into the rats. Quantitative measurements of water content and the concentration of EB were performed. [Ca2+]i was determined in calcium fluorescent indication Fura-2/AM loaded neuronal synaptosome with a spectrofluorophotometer. To observe the effect of MK-801 and nimodipine, we administered MK-801 48 hours and 24 hours before the injection of PB in MK-801 pretreatment group, and nimodipine after the injection of PB in nimodipine treatment group. The specific binding of NMDA receptor was measured with [3H]-MK-801 in the neuronal membrane of cerebral cortex. Results: The levels of water content and EB content of brain tissues, and [Ca2+]i in the neuronal synaptosomes increased more significantly in the PB-injected cerebral hemisphere in the PB group than those of normal control group and sham-operated control group (P0.05). Conclusions: The changes in the permeability of blood-brain barrier (BBB) and Ca2+-overload may participate in the pathogenesis of infectious brain edema. Treatment with nimodipine can dramatically reduce the damage of brain edema and demonstrate neuroprotective effect on brain edema by inhibiting the excess of Ca2+ influx and reducing the permeability of BBB. MK-801 pretreatment may inhibit the delayed Ca2+ influx into

    Infection with the Epstein-Barr virus (EBV) is a common disease and is mainly asymptomatic during childhood, whereas infectious mononucleosis with clinical signs such as fever, pharyngitis, lymphadenopathy and hepatosplenomegaly often occurs in adolescents and adults with primary infection. Acalculous cholecystitis has been reported as a rare complication. We report herein a case of acalculous cholecystitis accompanied by infectious mononucleosis by EBV, which was treated successfully by medical treatment. A 33-year-old woman who had been admitted by fever, pharyngitis and lymphadenopathy developed a right upper quadrant pain, that was diagnosed as acalculous cholecystitis based on an imaging study. Antibiotic treatment did not resolve the symptoms, and surgical intervention was considered. We diagnosed her as having infectious mononucleosis based on a typical physical presentation and seropositivity for the EBV viral capsid antigen, suggesting that the acalculous cholecystatis might have been a complication of the EBV infection. After the administration of glucocorticoid and acyclovir, the patient became afebrile and the abdominal pain disappeared. Though acalculous cholecystitis rarely accompanies infectious mononucleosis caused by EBV, clinicians should be aware of this complication to avoid unnecessary cholecystectomy. PMID:27529970

    Full Text Available From May to August 1999, we evaluated 401 patients from a pediatric hospital of Havana City. One group was composed of 113 patients with diarrhea admitted to the Gastroenterology ward and a second consisted of 288 patients without diarrhea, admitted for other reasons, and hospitalized within the same time period. Three stool samples were collected from each child and were examined using three parasitological techniques. When we compared the frequency of parasite species between both groups, we found Cryptosporidium spp. and Cyclospora cayetanensis, only in the group of children with diarrhea (P 0.05. In addition, in those children infected with Cryptosporidium, the diarrhea had a more prolonged duration (P < 0.01, while those infected with Cyclospora, the abdominal cramps or pain, and acute diarrhea were more frequently detected (P < 0.01. Our results showed that emerging intestinal coccidia are pathogens strongly associated in this group of children with diarrhea.

    During early Meiji era in Japan, there were frequent epidemics of fatal acute communicable diseases such as cholera, dysentery and smallpox, and preventive measures and preparations for acute infectious diseases were urgently needed. Together with improvement of scientific preparations, the Communicable Disease Prevention Law was promulgated in 1897. Then gradually until 1940's, the focus of preventive measures have been shifted from acute infectious diseases to chronic ones, particularly tuberculosis. After the World War II, except the short period of social confusion, major legally-defined communicable diseases had been decreasing rapidly mainly due to the use of antibiotics and improvement of environmental sanitation. At the same time, the introduction of preventive vaccination marked a new era for the prevention of infectious diseases and was largely responsible for the remarkable decrease of infant mortality in Japan. Recently the concept of defense by vaccination against infectious diseases has evolved from group-oriented to individual-oriented, so that the Preventive Vaccination Law was drastically revised in 1994. Currently, effective counter-measures against newly emerged infectious diseases, as viral hepatitis, institution-acquired infection, viral hemorrhagic fever etc., have been implemented. For the future, improvement of infections disease surveillance, vaccine development and expansion of vaccination coverage along with monitoring side-effects, preventive health education on AIDS/STDs, addressing the special needs of foreigners living in Japan and international collaboration for disease control abroad are all vital to the success of protection of the public's health from infectious diseases in Japan.

    In this study demographic, clinical, paraclinical, microbiological, and therapeutic features of patients with community-acquired acute bacterial meningitis admitted to a referral center for infectious diseases in Iran, have been evaluated. Medical records of adult (> 18 years) individuals with confirmed diagnosis of community-acquired bacterial meningitis during a 4-year period were retrospectively reviewed. All required data were obtained from patients' medical charts. Available findings about antimicrobial susceptibility of isolated bacteria from CSF and/or blood were also collected. Kirby-Bauer disc diffusion method was used to determine their antimicrobial susceptibility profile. Details of medical management including antibiotic regimen, duration, patients' outcome, and possible sequelae of meningitis were recorded. The most commonly isolated microorganism from CSF or blood of patients was Streptococcus pneumonia (33.33%) followed by Neisseria meningitidis (27.78%) and Haemophilus influenza (16.67%). The most common antimicrobial regimen was ceftriaxone plus vancomycin (69.44%) followed by ceftriaxone plus vancomycin plus ampicillin (11.11%). Neurological sequelae of meningitis including cranial nerve palsy, deafness, and hemiparesis were identified in 4 (11.11%), 2 (5.56%), and 1 (2.78%) subjects, respectively. Regarding mortality, only 3 (8.33%) patients died from bacterial meningitis and the remaining 33 individuals discharged from the hospital. In conclusion, findings of the current study demonstrated that the mean incidence of acute bacterial meningitis in a referral infectious diseases ward in Iran was 9 episodes per year. The majority cases of community-acquired acute bacterial meningitis admitted to our center had negative CSF culture and classic triad of meningitis was absent in them. PMID:27610176

    Chinese patent medicines play an important role in veterinary clinical use. The aim of this study is to research the anti-infection effect of Chinese patent medicine "Wuhuanghu" for the treatment of porcine infectious pleuropneumonia and to evaluate the safety of "Wuhuanghu" in order to provide a comprehensive understanding of its toxicity. The anti-infection results showed that the treatment with "Wuhuanghu" could significantly inhibit pneumonia and decrement of the pneumonia in high, medium and low doses of "Wuhuanghu" groups were 70.97%, 61.29% and 58.06% respectively. The acute toxicity test showed that rats in the highest group (5000mg/kg) had no death and no abnormal response, suggesting the LD50 of "Wuhuanghu" was more than 5000mg/kg. The subchronic toxicity study showed that hematology indexes in all groups had no obvious differences; blood biochemical index, only albumin and total cholesterol in middle and low doses of "Wuhuanghu" groups were significantly decreased when compared with control group. The clinical pathology showed that the target organ of "Wuhuanghu" was liver. The safety pharmacology study indicated that "Wuhuanghu" had no side effects on rats. In conclusion, "Wuhuanghu" has therapeutic and protective effects to porcine infectious pleuropneumonia in a dose-dependent manner and "Wuhuanghu" is a safe veterinary medicine. PMID:26245812

    Full Text Available Background Rotavirus is a major cause of severe diarrhea and dehydration in children worldwide. Data on the burden of disease in Indonesia is limited. Objective To provide an epidemiological profile of rotavirus infection among children hospitalized for diarrhea in Mohammad Hoesin Hospital, Palembang. Methods In January - December 2006, a prospective, hospital-based surveillance was carried out in children aged less than five years, presenting with diarrhea. Stool samples were examined for rotavirus using enzyme immunoassay (EIA. G- and P-typing were performed on specimens confirmed to be positive by EIA. Results A total of 513 fecal specimens from 534 children were tested for rotavirus. Rotavirus was detected in 64% of the specimens, mostly of the G9 type (62.5%. Incidence of rotavirus diarrhea was highest in the 6 month to 2 years age group (60.4%. Children with rotavirus diarrhea were more likely to present with dehydration, compared to those with non-rotavirus diarrhea (94% vs 70%, respectively, P=0.03. Conclusion Rotavirus was the most common pathogen found in children with diarrhea. Rotavirus was detected in 64% of pediatric diarrheal specimens tested in our study. This finding warrants the use of a large-scale program to prevent disease, such as vaccination against rotavirus. [Paediatr Indones. 2012;52:22-7].

Feces from diarrhea patients were enriched in EC broth. Diarrheagenic Escherichia coli were primary screened by multiple polymerase chain reaction (PCR) using 7 virulence genes of eaeA, aggR, ipaH, stx1, stx2, lt, stIb and the gene of 16S rRNA rrs. Then, the diarrheagenic Escherichia coli were isolated from positive enrichment medium. I-solates were conducted with biochemical identification, virulence genes detection and sero-groups testing. A total of 170 fecal specimens were collected and 20 diarrheagenic Escherichia coli were isolated, among which 11 strains were enteropathogenic Escherichia coli (EPEC) with all atypical EPEC, 7 strains were enteroaggregative Escherichia coli (EAEC) , and 2 strains were enterotoxigenic Escherichia coli (ETEC). Results showed that the infection of diarrheagenic Escherichia coli was mainly in children aged less than 5 years in Changzhi area. In addition to EPEC, EAEC occupied a large proportion. It's suggested that the test of virulence genes should combine with traditional sero-typing in the screening of diarrheagenic Escherichia coli infection.

    The current report aims to investigate the prevalence and resistance patterns of Salmonella in children with acute bacterial diarrhea. A total of 1045 stool specimens were collected from outpatients and inpatients with acute bacterial diarrhea admitted to Children's Hospital, Fudan University, from 1 July to 30 September in 2010. Salmonella spp. Was identified by culture isolation method. Antimicrobial susceptibility was tested via the Kirby-Bauer method. Salmonella was found in 160 specimens. The total infection rate was 15.3% (160/1045). The infection rate was 23. 6% (119/505) in children under 1-year old, which was significant higher than those in children aged 1 to 5 years (7. 6%, 32/423) and older (7.7%, 9/117) (x2 =2 090, P<0. 001). Twenty-one serotypes of Salmonella were found. Salmonella typhimurium accounted for 40.6% (65/160), Salmonella enteritidis accounted for 25.0% (40/160), and the others accounted for 34.4% (55/160). The resistance rates of Salmonella typhimurium and Salmonella enteritidis to ampicillin were 91. 4% and 69. 0%, to ceftriaxone 29. 3% and 6. 9%, and to cefotaxime 29.3% and 6.9%, respectively. The sensitivity rates of Salmonella typhimurium and Salmonella enteritidis to cefmetazole and fosfomycin were above 90%. These results suggest that Salmonella was the dominant pathogenic bacterium associated with acute bacterial diarrhea in children in our hospital in 2010 summer.The children under 1-year old were more susceptible to Salmonella infection. The prevalence serotypes were Salmonella typhimurium and Salmonella enteritidis and we found that they exhibited varying resistance to the third-generation cephalosporin.%本文旨在了解急性细菌感染性腹泻患儿中沙门菌的感染现状及其耐药性.采集2010年7月1日~2010年9月30日复旦大学附属儿科医院门诊及住院急性细菌感染性腹泻患儿的粪便标本,进行沙门菌分离、培养及鉴定,采用Kirby-Bauer法进行药敏试验.共收集急性细菌

    Acute otitis media is one of the most common infectious diseases diagnosed in children. Antibiotic treatment use remains controversial. This summary aims to evaluate the effectiveness and safety of antibiotics in children with acute otitis media. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified six systematic reviews including 18 randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded antibiotics reduce pain at 48-72 hours and reduce the risk of tympanic perforations in children with acute otitis media, but they do not reduce late recurrences and increase the risk of side effects (rash, vomiting and diarrhea).

    The objective of this study was to determine the abundance and distribution of γδ T lymphocytes in lymphoid tissue during acute infection with high (HV) or low virulence (LV) non-cytopathic bovine viral diarrhea virus (BVDV) in beef calves. This study was performed using tissue samples from a previous experiment in which thirty beef calves were randomly assigned to 1 of 3 groups: LV [n=10; animals inoculated intranasally (IN) with LV BVDV-1a (strain SD-1)], HV [n=10; animals inoculated IN with HV BVDV-2 (strain 1373)], and control (n=10; animals inoculated with cell culture medium). On day 5 post inoculation, animals were euthanized, and samples from spleen and mesenteric lymph nodes (MLN) were collected to assess the abundance of WC1(+) γδ T cells. A higher proportion of calves challenged with BVDV showed signs of apoptosis and cytophagy in MLN and spleen samples compared to the control group. A significantly lower number of γδ T cells was observed in spleen and MLN from calves in HV and LV groups than in the control calves (Pcells in mucosal and systemic lymphoid tissues at five days after challenge in beef calves. This reduction in γδ T cells in the studied lymphoid tissues could be also due to lymphocyte trafficking to other tissues.

    1997-01-01

    Full Text Available Persistent diarrhea (i.e. acute episodes lasting more than 14 days has been recognized by the WHO as a major public health problem in developing countries and a research topic of high priority. Persistent diarrhea is often associated with malnutrition, growth faltering, and a substantial risk of mortality in children below 5 years of age. Reported incidence and case-fatality rates from persistent diarrhea vary substantially. Substantial disagreement exists regarding definition, incidence and various putative risk factors. Resolution of such measurement related problems will allow for an accurate estimate of the force of morbidity and mortality from presistent diarrhea, while the elucidation of its risk factors will simplify policy making and the tailoring of intervention programs.

    Information about norovirus (NoV) infections in Central America is limited. Through a passive community and hospital pediatric diarrhea surveillance program, a total of 542 stool samples were collected between March 2005 and February 2006 in León, Nicaragua. NoV was detected in 12% (65/542) of the children; of these, 11% (45/409) were in the community and 15% (20/133) were in the hospital, with most strains (88%) belonging to genogroup II. NoV infections were age and gender associated, with children of <2 years of age (P < 0.05) and girls (P < 0.05) being most affected. Breast-feeding did not reduce the number of NoV infections. An important proportion (57%) of NoV-infected children were coinfected with diarrheagenic Escherichia coli. A significant proportion (18/31) of NoV-positive children with dehydration required intravenous rehydration. Nucleotide sequence analysis (38/65) of the N-terminal and shell region in the capsid gene revealed that at least six genotypes (GI.4, GII.2, GII.4, GII.7, GII.17, and a potentially novel cluster termed "GII.18-Nica") circulated during the study period, with GII.4 virus being predominant (26/38). The majority (20/26) of those GII.4 strains shared high nucleotide homology (99%) with the globally emerging Hunter strain. The mean viral load was approximately 15-fold higher in children infected with GII.4 virus than in those infected with other G.II viruses, with the highest viral load observed for the group of children infected with GII.4 and requiring intravenous rehydration. This study, the first of its type from a Central American country, suggests that NoV is an important etiological agent of acute diarrhea among children of <2 years of age in Nicaragua.

    Information about norovirus (NoV) infections in Central America is limited. Through a passive community and hospital pediatric diarrhea surveillance program, a total of 542 stool samples were collected between March 2005 and February 2006 in León, Nicaragua. NoV was detected in 12% (65/542) of the children; of these, 11% (45/409) were in the community and 15% (20/133) were in the hospital, with most strains (88%) belonging to genogroup II. NoV infections were age and gender associated, with children of <2 years of age (P < 0.05) and girls (P < 0.05) being most affected. Breast-feeding did not reduce the number of NoV infections. An important proportion (57%) of NoV-infected children were coinfected with diarrheagenic Escherichia coli. A significant proportion (18/31) of NoV-positive children with dehydration required intravenous rehydration. Nucleotide sequence analysis (38/65) of the N-terminal and shell region in the capsid gene revealed that at least six genotypes (GI.4, GII.2, GII.4, GII.7, GII.17, and a potentially novel cluster termed “GII.18-Nica”) circulated during the study period, with GII.4 virus being predominant (26/38). The majority (20/26) of those GII.4 strains shared high nucleotide homology (99%) with the globally emerging Hunter strain.

    Full Text Available Zinc supplementation is a critical new intervention for treating diarrheal episodes in children. Recent studies suggest that administration of zinc along with new low osmolarity oral rehydration solutions / salts (ORS, can reduce the duration and severity of diarrheal episodes for up to three months. The World Health Organization (WHO and UNICEF recommend daily 20 mg zinc supplements for 10 - 14 days for children with acute diarrhea, and 10 mg per day for infants under six months old, to curtail the severity of the episode and prevent further occurrences in the ensuing -two to three months, thereby decreasing the morbidity considerably. This article reviews the available evidence on the efficacy and safety of zinc supplementation in pediatric diarrhea and convincingly concludes that zinc supplementation has a beneficial impact on the disease outcome.

    Probiotics are increasingly used for prevention and treatment of diarrhea more in children than in adults. Given the broad spectrum of diarrhea, this review focuses on the main etiologies: acute gastroenteritis, antibiotic-associated diarrhea (AAD), and necrotizing enterocolitis (NEC). For each, we reviewed randomized controlled trials, meta-analyses, and guidelines. For acute gastroenteritis we found 12 guidelines: 5 recommended probiotics and 7 did not. However, the guidelines containing positive recommendations provided proof of evidence from clinical trials and meta-analyses. Lactobacillus rhamnosus GG (LGG) and Saccharomyces boulardii had the most compelling evidence of efficacy as they reduced the duration of the disease by 1 day. For AAD 4 meta-analyses were found, reporting variable efficacy of probiotics in preventing diarrhea, based on the setting, patient's age, and antibiotics. The most effective strains were LGG and S. boulardii. For NEC, we found 3 randomized controlled trials, 5 meta-analyses, and 4 position papers. Probiotics reduced the risk of NEC enterocolitis and mortality in preterm babies. Guidelines did not support a routine use of probiotics and asked for further data for such sensitive implications. In conclusion, there is strong and solid proof of efficacy of probiotics as active treatment of gastroenteritis in addition to rehydration. There is solid evidence that probiotics have some efficacy in prevention of AAD, but the number needed to treat is an issue. For both etiologies LGG and S. boulardii have the strongest evidence. In NEC the indications are more debated, yet on the basis of available data and their implications, probiotics should be carefully considered.

  11. Post-irradiation diarrhea

    International Nuclear Information System (INIS)

    In radiotherapy of pelvic cancers, the X-ray dose to be delivered to the tumour is limited by the tolerance of healthy surrounding tissue. In recent years, a number of serious complications of irradiation of pelvic organs were encountered. Modern radiotherapy necessitates the acceptance of a calculated risk of complications in order to achieve a better cure rate. To calculate these risks, one has to know the radiation dose-effect relationship of normal tissues. Of the normal tissues most at risk when treating pelvic tumours only the bowel is studied. In the literature regarding post-irradiation bowel complications, severe and mild complications are often mixed. In the present investigation the author concentrated on the group of patients with relatively mild symptoms. He studied the incidence and course of post-irradiation diarrhea in 196 patients treated for carcinoma of the uterine cervix or endometrium. The aims of the present study were: 1) to determine the incidence, course and prognostic significance of post-irradiation diarrhea; 2) to assess the influence of radiotherapy factors; 3) to study the relation of bile acid metabolism to post-irradiation diarrhea; 4) to investigate whether local factors (reservoir function) were primarily responsible.

    Objective:To screen for the presence of mixed infection with rotavirus. Methods:The present study included 140 children aged less than 2 years with acute diarrhea. Fecal samples of all these patients were analyzed for the presence of astroviral antigen by enzyme immunoassay. Also 40 rotavirus positive fecal samples were screened for the presence of astrovirus. Results:In case of acute diarrhea in children the prevalence of astrovirus was around 34%(48/140). It was seen that even in rotavirus positive cases astrovirus co infection was 25%. Conclusions:Astrovirus is a growing problem which is often underrecognised. With the rotavirus vaccine licensure being imminent astrovirus will emerge out as the single most important cause of viral diarrhea.

    Daniel R Feikin

    Full Text Available BACKGROUND: Characterizing infectious disease burden in Africa is important for prioritizing and targeting limited resources for curative and preventive services and monitoring the impact of interventions. METHODS: From June 1, 2006 to May 31, 2008, we estimated rates of acute lower respiratory tract illness (ALRI, diarrhea and acute febrile illness (AFI among >50,000 persons participating in population-based surveillance in impoverished, rural western Kenya (Asembo and an informal settlement in Nairobi, Kenya (Kibera. Field workers visited households every two weeks, collecting recent illness information and performing limited exams. Participants could access free high-quality care in a designated referral clinic in each site. Incidence and longitudinal prevalence were calculated and compared using Poisson regression. RESULTS: INCIDENCE RATES RESULTING IN CLINIC VISITATION WERE THE FOLLOWING: ALRI--0.36 and 0.51 episodes per year for children <5 years and 0.067 and 0.026 for persons ≥ 5 years in Asembo and Kibera, respectively; diarrhea--0.40 and 0.71 episodes per year for children <5 years and 0.09 and 0.062 for persons ≥ 5 years in Asembo and Kibera, respectively; AFI--0.17 and 0.09 episodes per year for children <5 years and 0.03 and 0.015 for persons ≥ 5 years in Asembo and Kibera, respectively. Annually, based on household visits, children <5 years in Asembo and Kibera had 60 and 27 cough days, 10 and 8 diarrhea days, and 37 and 11 fever days, respectively. Household-based rates were higher than clinic rates for diarrhea and AFI, this difference being several-fold greater in the rural than urban site. CONCLUSIONS: Individuals in poor Kenyan communities still suffer from a high burden of infectious diseases, which likely hampers their development. Urban slum and rural disease incidence and clinic utilization are sufficiently disparate in Africa to warrant data from both settings for estimating burden and focusing interventions.

    Full Text Available Shigellosis is an important public health problem, especially in developing countries. Antibiotic treatment of bacterial dysentery, aimed at resolving diarrhea or reducing its duration is especially indicated whenever malnutrition is present. First-line drugs include ampicillin and trimethoprim sulfamethoxazole(TMP-SMX; however multidrug-resistance has occurred and careful antibiotic selection must be considered in prescribing .When epidemiologic data indicate a rise in resistancy, fluoroquinolones may be used in adults and oral third-generation cephalosporins and nalidixic acid in children. All children (n=2400 with acute diarrhea who were admitted to the Pediatric department of Dr.sheykh Hospital Mashhad, Iran from March 2004 to March 2005 were selected and their stool culture were obtained, then positive cultures (312 cases,13% were evaluated by antibiogram. This study showed that in heavily populated areas of IRAN like Mashhad, 97% shigella strain isolated from children with bloody diarrhea were sensitive to nalidixic acid, ciprofloxacin and cefixime and rarely susceptible to ampicillin and cotrimoxazole. There is increasing resistance of Shigella to most of the antibiotics in use, and for this reason, careful selection of antibiotics must use considered in each area. Development and use of new drugs are expensive and have severe limitations in the third world. Simple prophylactic alternatives are therefore, required, such as awareness of hygienic child care practices and early promotion of breast feeding. For treatment of shigellosis in infants Ceftriaxon, and in children Nalidixic Acid is recommended.

    Full Text Available The aim of the investigation was to estimate the relation of CD95 and DR3 receptors activation with apoptosis level of naive cytotoxic Т-lymphocytes (nCТL in children with acute infectious mononucleosis (AIM. Materials and Methods. The test materials were peripheral blood samples of healthy children and children with AIM. nCTL were isolated by negative immunomagnetic separation. Specific activation of CD95 and DR3 receptors was performed using monoclonal antibodies. An apoptosis level and expression of receptors were studied by flow cytometry. Results. The percentage of cell apoptosis decreased in children with AIM in freshly isolated nCTL, as well as in CD95 receptor activation compared to healthy children. nCTL apoptosis in healthy children regardless of culture conditions was accompanied by the reduced quantity of CD95+DR3– cells and CD95 expression density on their surface. In children with AIM the decrease of these indices required CD95 activation. Compared to healthy children, the percentage of CD95+DR3+ cells in children with AIM decreased in CD95 activation. In CD95 receptor activation in healthy children and children with AIM, the content of CD95+DR3+ cells correlated directly with an apoptosis level. DR3 receptor activation was accompanied neither by nCTL apoptosis level change nor the changed content of DR3+ cells in both healthy children and children with AIM. Conclusion. nCTL are less sensitive to apoptosis in children with AIM compared to healthy children. DR3 receptor activation results in no change of nCTL apoptosis level both in healthy children and children with AIM. CD95 activation in patients with AIM is accompanied by increased resistance of CD95+DR3– cells to apoptosis and the susceptibility to apoptosis of CD95+DR3+ cells. The evaluation of nCTL susceptibility to CD95-induced apoptosis in AIM can serve as a subtest to assess the state of a cell component of immune system.

    The most common cause of acute diarrhea in young children in developed and developing countries are rotaviruses. In developing countries, it is estimated that 20-70% of hospitalizations and close to one million children below the age of five die annually because of rotavirus infections. Of the seven groups (A-G) of rotaviruses, group A is usually the cause of rotavirus-associated diarrhea. Infections due to rotaviruses occur via the fecal-oral route. Previous studies from Libya showed that ro...

    Avian infectious laryngotracheitis (ILT) herpesvirus continues to cause sporadic cases of respiratory disease in chickens world-wide. Sources of transmission of ILT infection are three-fold, namely: chickens with acute upper respiratory tract disease, latently infected 'carrier' fowls which excrete infectious laryngotracheitis virus (ILTV) when stressed, and all fomites (inanimate articles as well as the personnel in contact with infected chickens). Infectious laryngotracheitis virus infectivity can persist for weeks to months in tracheal mucus or carcasses. Rigorous site biosecurity is therefore critical in ILT disease control. Furthermore, while current (modified live) ILT vaccines can offer good protection, the strains of ILTV used in vaccines can also produce latent infections, as well as ILT disease following bird-to-bird spread. The regional nature of reservoirs of ILTV-infected flocks will tend to interact unfavourably with widely varying ILT control practices in the poultry industry, so as to periodically result in sporadic and unexpected outbreaks of ILT in intensive poultry industry populations. Precautions for trade-related movements of chickens of all ages must therefore include an accurate knowledge of the ILT infection status, both of the donor and recipient flocks. PMID:10935275

    Diarrheal diseases remain a leading cause of morbidity and mortality for children in developing countries, while representing an important cause of morbidity worldwide. The World Health Organization recommended that low osmolarity oral rehydration solutions plus zinc save lives in patients with acute diarrhea, but there are no approved, safe drugs that have been shown to be effective against most causes of acute diarrhea. Identification of abnormalities in electrolyte handling by the intestine in diarrhea, including increased intestinal anion secretion and reduced Na(+) absorption, suggest a number of potential drug targets. This is based on the view that successful drug therapy for diarrhea will result from correcting the abnormalities in electrolyte transport that are pathophysiologic for diarrhea. We review the molecular mechanisms of physiologic regulation of intestinal ion transport and changes that occur in diarrhea and the status of drugs being developed to correct the transport abnormalities in Na(+) absorption that occur in diarrhea. Mechanisms of Cl(-) secretion and approaches to anti-Cl(-) secretory therapies of diarrhea are discussed in a companion review. PMID:24184676

  9. CT evaluation of infectious colitis

    International Nuclear Information System (INIS)

    Computed tomography (CT) is useful for evaluating the diagnosis of gastrointestinal disease, such as infectious colitis, in patients with severe pain and bloody diarrhea. During the 7 years between November 1993 and October 2000, 34 patients with infectious colitis (18 male, 16 female; mean age 42±19 yrs), received emergency CT and colonoscopy because of severe abdominal pain and dysentery. The following organisms were isolated: pathogenic Escherichia coli (12), 6 of which were O157: H7 (O-157), Salmonella species (11), Campylobacter species (5), Vibrio parahaemolyticus (3), Yersinia enterocolotica (2) and Shigella species (1). Thickening of the intestinal wall greater than 10 mm was seen in the ascending colon in the 6 cases with E. coli O157, in 5/11 cases with Salmonella, 4/5 with Campylobacter and 1/6 with non-O157 pathogenic E. Coli. marked intestinal wall thickening, greater than 20 mm, was seen in the ascending colon of the 4 of the patients with an O-157 infection. In all patients with O-157 colitis, slight ascites was noted in the pelvic space. In additions, ascites was also seen in 3/13 patients with Salmonella and 1/5 patients with Campylobacter colitis. The CT findings, in the patients with infectious colitis, are non-specific but knowledge and recognition of the findings will help in patient evaluation and proper treatment. (author)

    Full Text Available CONTEXT: Acute diarrhea is a common cause of hospitalization among children under 5 years of age. Knowing the prevalence and risk factors associated with the severity of acute diarrhea is essential to control morbidity and mortality. OBJECTIVE: Describe the prevalence of demographic, epidemiologic and clinical features of children under 6 years of age hospitalized for acute diarrhea, and investigate the association between these determinants and the severity of the diarrheic episode. METHOD: Retrospective, cross-sectional study, during the period from January, 2005 through December, 2008, in the municipality of Juiz de Fora, MG, Brazil. Files from 6,201 children from 0 to 6 years of age, hospitalized in two public teaching institutions (which account for 84% of all the hospitalizations in the municipality, were assessed. Acute diarrhea was defined as the presence of at least three evacuations of liquid or loose stools, within 24 hours, for a maximum period of 14 days. The patients with acute diarrhea were divided in two groups, according to disease severity, severe diarrhea being considered whenever hospitalization lasted for at least 4 days. Epidemiologic and clinical data were assessed and compared through the application of the chi-squared test and the binomial logistic regression model. RESULTS: The prevalence rate for admission due to acute diarrhea was 8.4%. The factors significantly associated with the severity of the diarrheic episode were: age under 6 months (P = 0.01, OR = 2.762; disease onset during fall (P = 0.033, OR = 1.742, presence of fever (P = 0.017, OR = 1.715 and antibiotic use during hospitalization (P = 0.000, OR = 3.872. CONCLUSIONS: Diarrhea is the third most common cause of hospitalization among children under 6 years of age in Juiz de Fora. Young age (under or equal to 6 months, fever, antibiotic use during hospitalization and disease onset during fall are risk factors associated with longer hospital stay

    1977-04-01

    Diarrhea, an increase in frequency of evacuation and in water content of the stool, is the result of three categories of mechanism--solute malabsorption, secretion of fluid and motility disturbance. Before diarrhea is considered an abnormal condition, any alteration in stool frequency and content must be related to an individual person's normal bowel habit and to norms for the population, but more than three bowel movements or the passage of liquid stools exceeding 300 g daily should, in general, be considered abnormal. A useful way of understanding the mechanism of diarrhea is to become familiar with the normal functions of the bowel in regard to water and electrolyte absorption and motility, and then to relate these functions to solute malabsorption, fluid secretion and motility disturbance.

    Objective To explore the status and significance of benign infantile convulsion with mild gastroenteritis ( BICE) in the spectrum of infantile convulsion with acute diarrhea. Methods One hundred and eighty - four cases of convulsion with acute diarrhea treated in our hospital from 2009 to 2011 were analyzed retrospectively. Results Among the 184 cases of convulsion with acute diarrhea, there were 58 cases of BICE, 49 cases of febrile seizures, 43 cases of epilepsy, 19 cases of viral encephalitis, 6 cases of hyponatremic encephalopathy, 5 cases of hypernatremic encephalopathy, 2 cases of toxic encephalopathy and 2 cases of hypocalcemie seizures. The average age of children with BICE was (17.47 ±7.90) months. The symptoms were generally mild with little or no signs of dehydration. The seizure occurred mostly during the first two days of the illness and was brief in a tetanic or clonic form. Positive rotavirus antigens were detected in 65.52% . There were no abnormal findings in the routine blood test, blood bioche-mistry, cerebrospinal fluid, cerebral computerized tomography/magnetic resonance imaging and electroencephalogram examinations. After hospitalization, the children were given fluids intravenously. Sodium pheno-barbital was administered after the first convulsion and if seizures recurred, diazepam was given intravenously. All children were fully recovered in 2 to 5 days after hospitalization. Conclusions BICE occurs frequently in the infantile convulsion with acute diarrhea and symptomatic treatment is sufficient in patient care. Thus, unnecessary medical tests and excessive treatment should be avoided.%目的 探讨轻度胃肠炎伴婴幼儿良性惊厥(BICE)在婴幼儿急性腹泻伴惊厥疾病谱中的地位及意义.方法 对2009-2011年收治的急性腹泻并有惊厥症状患儿的住院资料进行回顾性分析.结果 184例急性腹泻伴惊厥的病例中,轻度胃肠炎伴婴幼儿良性惊厥58例、热性惊厥49例、癫(痫)43

    A popular leisure activity, international travel can be associated with some infections. The most common travel-related illnesses appear to be gastrointestinal, dermatologic, respiratory, and systemic febrile syndromes. The pretravel medical consultation includes immunizations, malaria chemoprophylaxis, self-treatment for traveler's diarrhea, and advice on the prevention of a myriad of other infectious causes including dengue, chikungunya, rickettsiosis, leptospirosis, schistosomiasis, and strongyloidiasis. Travel to locations experiencing outbreaks such as Ebola virus disease, Middle East respiratory syndrome, avian influenza, and chikungunya call for specific alerts on preventive strategies. After travel, evaluation of an ill traveler must explore details of exposure, including destinations visited; activities; ingestion of contaminated food or drinks; contact with vectors, animals, fresh water, or blood and body fluids; and other potential exposures. Knowledge of the geographic distribution of infectious diseases is important in generating the differential diagnoses and testing accordingly. Empiric treatment is sometimes necessary when suspicion of a certain diagnosis is strong and confirmatory tests are delayed or lacking, particularly for infections that are rapidly progressive (for example, malaria) or for which timing of testing is prolonged (such as leptospirosis).

    Salmonella enterica serovar Typhimurium (aka, S. typhimurium) is a facultative intracellular pathogen that causes ~40,000 reported cases of acute gastroenteritis and diarrhea a year in the United States. To develop a deeper understanding of the infectious state of S. typhimurium, liquid chromatography-mass spectrometry-based “bottom-up” proteomics was used to globally analyze the proteins present under specific growth conditions. Salmonella typhimurium LT2 strain cells were grown in contrasting culture conditions that mimicked both natural free-living conditions and an infectious state, i.e., logarithm phase, stationary phase and Mg-depleted medium growth. Initial comparisons of the LT2 strain protein abundances among cell culture conditions indicate that the majority of proteins do not change significantly. Not unexpectedly, cells grown in Mg-depleted medium conditions had a higher abundance of Mg2+ transport proteins than found in other growth conditions. A second more virulent Salmonella typhimurium strain (14028) was also studied with these growth conditions and used to directly compare to the LT2 strain. The strain comparison offers a unique opportunity to compare and contrast observations in these closely related bacteria. One particular protein family, propanediol utilization proteins, was drastically more abundant in the 14028 strain than in the LT2 strain, and may be a contributor to increased pathogenicity in the 14028 strain.

    Reust, Carin E; Williams, Amy

    2016-05-15

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

    Patient: Male, 46 Final Diagnosis: Celiac crisis Symptoms: Abdominal pain • chronic diarrhea • lightheadedness • weakness • weight loss Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Celiac disease is a hypersensitivity enteropathy that can have various presentations in adults. Rarely, patients can present with severe lab abnormalities, dehydration and weight loss caused by celiac disease – a celiac crisis. Case Report: A 46-year-old male with a past medical history significant for diabetes mellitus, type 2 (DM2) and recently treated Bell’s Palsy presented to the emergency room complaining of weakness, diarrhea and lightheadedness. On presentation, the patient had a systolic blood pressure (SBP) of 60 mm Hg and a lactic acidosis with pH of 7.28. Infectious etiologies of diarrhea were ruled out. The patient had an EGD which showed erythema of the duodenal bulb. Serum anti-gliadin and anti-TTG IgA were both elevated suggesting Celiac disease. Biopsies showed histopathology consistent with celiac disease. The patient’s diarrhea resolved after initiation of a gluten free diet. He gained 25 kilograms after discharge and did not require further hospitalizations for diarrhea. Conclusions: Celiac crisis is a very rare presentation of celiac disease in adults but nonetheless should be considered in patients with marked metabolic derangements in the setting of osmotic diarrhea. Treatment consists of a gluten free diet and may require management with steroids and total parenteral nutrition (TPN). PMID:27492679

  6. Effective prophylaxis against rotavirus diarrhea using a combination of Lactobacillus rhamnosus GG and antibodies

    2007-09-01

    Full Text Available Abstract Background Rotavirus is a worldwide cause of infectious infantile diarrhea that claims over 600,000 lives annually. Recently, two new vaccine candidates have been developed but their efficacy in developing countries, still remains to be proven. Oral delivery of specific immunoglobulins provides passive immunity and is a fast acting treatment for rotavirus diarrhea. Probiotic bacteria have also gained considerable attention lately as treatment for rotavirus diarrhea. Here we report an evaluation of the therapeutic potential of different probiotics and their combination with anti – rotavirus antibodies in a mouse model of rotavirus diarrhea. Results Of the six probiotic bacteria tested, Lactobacillus rhamnosus strain GG had the strongest influence in reducing prevalence, duration and severity of diarrhea and was therefore chosen for combination treatment with immunoglobulins. The combination treatment reduced the diarrhea outcome measures significantly, prevented histopathological changes and reduced the virus load in the intestines. Conclusion The advantages associated with immunoglobulins and probiotics based therapy is that the treatment provides a rapid therapeutic effect and is cost efficient. These components do not require special storage conditions and could potentially complement the rehydration therapy that is currently used.

  7. Development and validation of a biomarker for diarrhea-predominant irritable bowel syndrome in human subjects.

    Directory of Open Access Journals (Sweden)

    Mark Pimentel

    Full Text Available Diarrhea-predominant irritable bowel syndrome (IBS is diagnosed through clinical criteria after excluding "organic" conditions, and can be precipitated by acute gastroenteritis. Cytolethal distending toxin B (CdtB is produced by bacteria that cause acute gastroenteritis, and a post-infectious animal model demonstrates that host antibodies to CdtB cross-react with vinculin in the host gut, producing an IBS-like phenotype. Therefore, we assessed circulating anti-CdtB and anti-vinculin antibodies as biomarkers for D-IBS in human subjects. Subjects with D-IBS based on Rome criteria (n=2375 were recruited from a large-scale multicenter clinical trial for D-IBS (TARGET 3. Subjects with inflammatory bowel disease (IBD (n=142, subjects with celiac disease (n=121, and healthy controls (n=43 were obtained for comparison. Subjects with IBD and celiac disease were recruited based on the presence of intestinal complaints and histologic confirmation of chronic inflammatory changes in the colon or small intestine. Subjects with celiac disease were also required to have an elevated tTG and biopsy. All subjects were aged between 18 and 65 years. Plasma levels of anti-CdtB and anti-vinculin antibodies were determined by ELISA, and compared between groups. Anti-CdtB titers were significantly higher in D-IBS subjects compared to IBD, healthy controls and celiac disease (P<0.001. Anti-vinculin titers were also significantly higher in IBS (P<0.001 compared to the other groups. The area-under-the-receiver operating curves (AUCs were 0.81 and 0.62 for diagnosis of D-IBS against IBD for anti-CdtB and anti-vinculin, respectively. Both tests were less specific in differentiating IBS from celiac disease. Optimization demonstrated that for anti-CdtB (optical density≥2.80 the specificity, sensitivity and likelihood ratio were 91.6%, 43.7 and 5.2, respectively, and for anti-vinculin (OD≥1.68 were 83.8%, 32.6 and 2.0, respectively.

    Antimicrobials are effective agents used to combat virulent bacterial, yeast, and fungal infections that may otherwise cause rampant disease leading to skyrocketing social/economic costs and possible epidemic morbidity and mortality rates. Antibiotics are designed to attack specific bacterial pathogens but, in the process, indiscreetly reduce the number of beneficial human microbiota that is part of the gut-associated lymphatic tissue. Broad-spectrum antibiotics can upset this uniquely balanced gut ratio, allowing pathogens to propagate in a largely unrestrained environment, which may result in antibiotic-induced diarrhea. Critical illness, age, immunosuppression, exposure to nosocomial microorganisms, and the length of hospitalization are additional factors that contribute to the overgrowth of opportunistic pathogens. In mild to moderate cases of diarrhea, absorptive impairment may occur, thereby reducing micro/macronutrient assimilation, resulting in malnutrition and growth issues in children. In severe cases, infectious diarrhea can have devastating complications. Of particular interest is the bacterium Clostridium difficile, which has the potential to cause a host of symptoms ranging from mild diarrhea to severe life-threatening conditions. C. difficile infection can increase mortality rates by 10%-30%. Probiotic supplementation may prevent and treat antibiotic-associated diarrhea. Specific probiotics may modulate the intestinal mucosa by antagonizing pathogens through the production of antimicrobial compounds and chemicals, thereby reducing the rate of nosocomial infection and recurrence of C. difficile.

    Infectious diseases are still among the leading causes of death worldwide due to their persistence, emergence, and reemergence. As the recent Ebola virus disease and MERS-CoV outbreaks demonstrate, the modern epidemics and large-scale infectious outbreaks emerge and spread quickly. Air transportation is a major vehicle for the rapid spread and dissemination of communicable diseases, and there have been a number of reported outbreaks of serious airborne diseases aboard commercial flights including tuberculosis, severe acute respiratory syndrome, influenza, smallpox, and measles, to name a few. In 2014 alone, over 3.3 billion passengers (a number equivalent to 42% of the world population) and 50 million metric tons of cargo traveled by air from 41,000 airports and 50,000 routes worldwide, and significant growth is anticipated, with passenger numbers expected to reach 5.9 billion by 2030. Given the increasing numbers of travelers, the risk of infectious disease transmission during air travel is a significant concern, and this chapter focuses on the current knowledge about transmission of infectious diseases in the context of both transmissions within the aircraft passenger cabin and commercial aircraft serving as vehicles of worldwide infection spread.

    The objective was to compare, during a 5-day therapy, the efficacy and tolerability of an antihistaminic antitussive syrup, oxomemazine, combining a small quantity of guaifenesine (T), with a centrally acting antitussive, clobutinol (S), in adult patients aged from 18 to 70 years and presenting with a dry cough of infectious origin. This study was performed by 22 general practitioners and 130 ambulatory patients were enrolled. The primary criterion of this multicenter, randomized, single blind study was to compare the evolution of cough intensity using a Visual Analog Squale (VAS) graduated from 0 to 10 cm. Nine secondary criteria including tolerability were also assessed. With regard to cough intensity, the treatments were not equivalent. A greater reduction was observed with T (-5.2 +/- 2.3 versus -4.3 +/- 2.3). This result was confirmed by a further reduction in cough intensity at days: 2 (p = 0.04), 4 (p = 0.05), and 5 (p = 0.02). The frequency of cough disappearance before the end of the study was significantly greater for T than for S: 46% versus 29% (p = 0.05). The time before disappearance of the cough was 4.0 + 1.1 days for both medicines. Induction of sleep and the frequency of nocturnal wakening were significantly better for T from day 4 (p = 0.02). The drowsiness induced by T meant that diurnal quality of life was better with S on days 1 (p = 0.002) and 2 (p = 0.01). Tolerability was similar for both medicines. In conclusion, as a symptomatic treatment of dry cough, T is efficient and well tolerated. Moreover, we have observed a tendency towards superior efficacy of T than S. T is therefore a useful alternative in the therapeutic armamentarium available to the general practitioner.

    Diarrhea represents a major health problem for travelers to developing countries. Although the syndrome is usually self-limited and recovery occurs in the majority of cases without any specific form of therapy, there is a need for safe and effective ways of preventing and treating it. Since the syndrome is most often caused by an infection acquired by ingesting fecally contaminated food or beverages, precautions regarding dietary habits remain the cornerstone of prophylaxis, but dietary self-restrictions do not always translate to reduced rates of diarrheal illness. Administration of probiotics (e.g. lactobacilli or Saccharomyces boulardii) and immunoprophylaxis with the newer oral cholera vaccines have been tried with promising results. Antimicrobials remain, however, the most successful form of prophylaxis, being effective in up to 90% of travelers. For those with impaired health who will take prophylaxis, systemic agents with proved efficacy should be recommended. For other otherwise healthy persons, poorly absorbed agents are preferable in order to avoid the serious, albeit rare, toxicity of systemic drugs. The key factor in the management of acute watery traveler's diarrhea, particularly in infants and young children, is the restoration of water and electrolyte balance. This does not reduce the duration of the illness but will limit dehydration and prevent acidosis. Many patients will require no additional therapy, whereas some will need pharmacologic treatment to shorten the duration of diarrhea or to relieve the accompanying symptoms, like abdominal discomfort, nausea and vomiting. A typical 3- to 5-day illness can be reduced to approximately 1 day by trimethoprim-sulfamethoxazole (TMP-SMX) combination. Some other systemic antimicrobials have been successfully used but, during the last few years, the 4-fluoroquinolone drugs have received considerable attention and have been shown to be highly effective in reducing the duration of traveler's diarrhea.

    Full Text Available Developing countries face a huge burden of infectious diseases, a number of which co-exist. This paper estimates the pattern and variation of malaria and diarrhea coexistence in Chikhwawa, a district in Southern Malawi using bivariate multilevel modelling with Bayesian estimation. A probit link was employed to examine hierarchically built data from a survey of individuals (n = 6,727 nested within households (n = 1,380 nested within communities (n = 33. Results show significant malaria [ ] and diarrhea [ ] variations with a strong correlation between them [ ] at household level. There are significant malaria [ ] and diarrhea [   ] variations at community level but with a small correlation [ ] between them. There is also significant correlation between malaria and diarrhea at individual level [ 0.241]. These results suggest a close association between reported malaria-like illness and diarrheal illness especially at household and individual levels in Southern Malawi.

    Full Text Available Over the past decade in Canada, infectious disease outbreaks have repeatedly been in the public spotlight. The Escherichia coli outbreak in Walkerton, Ontario (1, the severe acute respiratory syndrome outbreak in Toronto, Ontario (2 and the Clostridium difficile hospital outbreak in Montreal, Quebec (3, have cost lives, grabbed headlines and stressed local health care systems. Each outbreak raised questions about our ability to prevent outbreaks, detect outbreaks early, and respond efficiently and effectively to infectious disease crises; these outbreaks also highlighted gaps in Canada's preparedness for managing major infectious disease problems when multiple jurisdictions are involved (4. Canada's poor track record of tuberculosis control in the north (5 raises the concern that this problem is not limited to crisis situations, but rather has deeper implications for the management of infectious diseases in Canada.

    BACKGROUND: Infectious mononucleosis-related Epstein-Barr virus (EBV) infection has been associated with an increased risk of Hodgkin's lymphoma in young adults. Whether the association is causal remains unclear. METHODS: We compared the incidence rates of Hodgkin's lymphoma in two population......-based Danish cohorts of patients who were tested for infectious mononucleosis: 17,045 with serologic evidence of having had acute EBV infection, and 24,614 with no such evidence. We combined the cohort of patients who had serologically verified infectious mononucleosis with a cohort of 21,510 Swedish patients...... with infectious mononucleosis (combined total, 38,555). Biopsy specimens of Hodgkin's lymphomas occurring during follow-up in this combined cohort were tested serologically for the presence of EBV.

    Full Text Available Infectious laryngotracheitis (ILT herpesvirus continues to cause outbreaks of respiratory disease in chickens world-wide. Sporadic cases of ILT occur in all classes of birds, including hobby/show/game chickens, broilers, heavy breeders, and commercial laying hens. These epornitics of ILT tend to occur where there are large populations of naïve, unvaccinated birds, i.e., in concentrated areas of broiler production. ILT virus can be transmitted through (a chickens with acute upper respiratory tract disease, (b latently infected "carrier" fowls, and (c fomites and contaminated persons. Chicken flocks which are endemic infected with ILT virus occur only in some regions of countries or even in particular multiple-age production farms. In these cases modified live vaccines are actually used, even though these biological products, as well as wild ILTV strains, can establish latent infections. In the case of heavy breeders and laying hens, which are typically vaccinated against ILT, sporadic cases are often related to errors in vaccine application and to biosecurity failures.

Primary IE was diagnosed in 15, secondary - in 35 cases. 7 pts had acute and 43 — subacute course. 40 pts had definite and 10 — probable IE. Results. Mean period till correct diagnosis establishment was 112± 116,5 days. Diagnostic difficulties were more frequent in subacute variant of IE (p=0,03. Heart diseases prevailed among cardiac risk factors (p=0,0l. Clinical picture of IE was very polymorphous. Glucocorticoids (GC were administered to 21 pts in addition to antibiotics due to signs of organ immunopatology and high laboratory measures of immune activity. Positive effect of glucocorticoids was achieved in 64% of pts. Conclusion. Development of immunological changes complicates timely diagnosis of IE and requires exclusion of different diseases including rheumatic pathology. IE treatment strategy does not exclude administration of GC low doses for prominent immunopathological signs in addition to massive antibacterial therapy.

    Background: European air travelers returning from Algeria, Egypt, Mexico, Morocco, and Tunisia were interviewed about their experience of travelers' diseases upon arrival in Brussels. Diarrhea was mentioned by 37% of the adults and 27% of the children. These subjects were questioned about the types of measures taken, type and duration of drug treatment (if any), and about duration of diarrhea and side effects experienced. Methods: Final analysis was performed based on 2160 interviews. The largest proportion of diarrhea was reported in the age group 15-24 years (46%). Results: The majority of the 2160 subjects had opted for drug treatment (81%): 927 subjects for loperamide alone, 235 for loperamide in combination with nifuroxazide, and 178 for nifuroxazide alone. Other drugs had been used less frequently. The median time to recovery was 2.4 days with loperamide compared to 3.2 days with nifuroxazide and to 3.4 days for the no-treatment group. Conclusions: A stratification of the results by severity of the diarrhea suggests a rank of antidiarrheal potency as follows: loperamide > nifuroxazide > no-drug treatment. The side effect with the highest incidence was constipation (2.4% with loperamide). (J Travel Med 2:11-15, 1995) Travelers' diarrhea is usually defined as the passage of at least three unformed stools per day or any number of such stools when accompanied by fever, abdominal cramping, or vomiting. The definition may be broadened to include more trivial bowel disturbance.1,2 The duration of this self-limited disease generally is 3 to 5 days. Medical intervention aims at shortening the duration of disease, thus allowing the sufferer to resume his or her usual activities at an early stage. A shortened period of recovery to physical well-being has obvious favorable economic implications if the traveler is on business and may help the maintenance of a desired level of quality of life while a traveler is on holiday.

    We aimed to investigate the effects of dietary combination of honey and Ardeh on chemotherapy-induced complications in patients with acute myeloid leukemia (AML). A total of 107 AML patients who underwent chemotherapy for at least 30 consecutive dayswere recruited to this double-blind randomized placebo-controlled clinical-trial which was conducted in the Imam Reza and Ghaem teaching hospitals (Mashhad, Iran). They weredivided into two age and sex-matched groups: 58 treated and 49 untreated patients. A combination of 50 grams of honey and 150 grams of Ardehwas added to the treated group's diet for 30consecutive days, three times each day; while the untreated group received their regular diet.Both groups received their standard medication for AML as well. After one month, they were all examined and lab tests were done on them by an internist and laboratory technicians who were blinded to the subject allocations. Mean value of WBC count in treated group was significantly lower than that of untreated group. Duration of fever and admission in the hospital due to fever were both significantly lower in the treated group (P=0.014, P=0.032 respectively). Total gastrointestinal complications were significantly less in the treated group one month after therapy with the special honey and Ardeh compound.No unusual or unexpected side effects were observed. Honey and Ardehare easily accessible materials that can be helpfully administered in AML patientsreceiving chemotherapy, since their useful effects in ameliorating gastrointestinal complications and reducingfever and neutropenia in AML patients have been shown.

    BACKGROUND Celiac disease is a hypersensitivity enteropathy that can have various presentations in adults. Rarely, patients can present with severe lab abnormalities, dehydration and weight loss caused by celiac disease - a celiac crisis. CASE REPORT A 46-year-old male with a past medical history significant for diabetes mellitus, type 2 (DM2) and recently treated Bell's Palsy presented to the emergency room complaining of weakness, diarrhea and lightheadedness. On presentation, the patient had a systolic blood pressure (SBP) of 60 mm Hg and a lactic acidosis with pH of 7.28. Infectious etiologies of diarrhea were ruled out. The patient had an EGD which showed erythema of the duodenal bulb. Serum anti-gliadin and anti-TTG IgA were both elevated suggesting Celiac disease. Biopsies showed histopathology consistent with celiac disease. The patient's diarrhea resolved after initiation of a gluten free diet. He gained 25 kilograms after discharge and did not require further hospitalizations for diarrhea. CONCLUSIONS Celiac crisis is a very rare presentation of celiac disease in adults but nonetheless should be considered in patients with marked metabolic derangements in the setting of osmotic diarrhea. Treatment consists of a gluten free diet and may require management with steroids and total parenteral nutrition (TPN). PMID:27492679

    Background Nicaragua was the first developing nation to implement routine immunization with the pentavalent rotavirus vaccine (RV5). In this RV5-immunized population, understanding infectious etiologies of childhood diarrhea is necessary to direct diarrhea treatment and prevention efforts. Methods We followed a population-based sample of children less than 5 years in León, Nicaragua for diarrhea episodes through household visits. Information was obtained on RV5 history and sociodemographics. Stool samples collected during diarrhea episodes and among healthy children underwent laboratory analysis for viral, bacterial, and parasitic enteropathogens. Detection frequency and incidence of each enteropathogen was calculated. Results The 826 children in the cohort experienced 677 diarrhea episodes during 607.5 child-years of exposure time (1.1 episodes per child-year). At least one enteropathogen was detected among 61.1% of the 337 diarrheal stools collected. The most common enteropathogens among diarrheal stools were: norovirus (20.4%), sapovirus (16.6%), enteropathogenic Escherichia coli (EPEC, 11.3%), Entamoeba histolytica/dispar (8.3%), Giardia lamblia (8.0%), and enterotoxigenic E.coli (ETEC, 7.7%), with rotavirus detected among 5.3% of diarrheal stools. EPEC and ETEC were frequently detected among stools from healthy children. Among children with diarrhea, norovirus was more commonly detected among younger children (< 2 years) and G. lamblia was more commonly detected among older children (2-4 years). The mean age of rotavirus detection was 34.6 months. Conclusions In this Central American community following RV5 introduction, rotavirus was not commonly detected among children with diarrhea. Prevention and appropriate management of norovirus and sapovirus should be considered to further reduce the burden of diarrheal disease. PMID:24879131

    The purpose of our study is to emphasize the central role of ultrasound (US) in finding the cause of abdominal pain in children. Ultrasound of the lower abdomen quadrant should be considered in all cases in which the clinical signs and symptoms are not diagnostic of appendicitis. There is a wide range of clinical syndromes and diseases which can easily be diagnosed using a high resolution ultrasound with adjunct of color and power Doppler. The spectrum of abnormalities includes appendicitis, mesenteric lymphadenitis, infectious ileocecitis, Crohn's disease, intussusception, ovarian cysts, and encysted cerebrospinal fluid. One of the most common causes of acute abdominal pain in children is acute terminal ileitis (infectious ileocecitis) with mesenteric lymphadenitis. Ultrasound is the best tool to rapidly differentiate this disease from acute appendicitis, and prevent unnecessary laparotomy (Ref. 12). PMID:16201735

    Rotavirus B (RVB) infection in cattle is poorly understood. The objective of this study was to describe the epidemiological features of repeated outbreaks of epidemic diarrhea due to RVB infection in adult cattle on a large dairy farm complex in Japan. In October 2002, approximately 550 adult cows and approximately 450 in February 2005 had acute watery diarrhea at several farms on the complex. Four months before the first outbreak, RVB antibody-positive rates at subsequently affected farms were significantly lower than at non-affected farms (30% to 32% versus 61% to 67%). During the acute phase of both outbreaks, RVB antibody-positive rates in diarrheal cows tested were as low as 15% to 26%. Most of the farms affected in the second outbreak were also involved in the first outbreak. Some adult cows with RVB diarrhea in the first outbreak showed not only RVB seroresponse, but also RVB shedding in the second outbreak, although none of these cows developed diarrhea. Nucleotide sequences of the VP7 and VP4 genes revealed a close relationship between RVB strains in both outbreaks. Taken together, these results indicate that outbreaks of epidemic RVB diarrhea in adult cows might be influenced by herd immunity and could occur repeatedly at the same farms over several years. To our knowledge, this is the first report on repeated RVB infections in the same cattle. PMID:27408331

    Full Text Available Diarrhea remains a major health issue in developing countries, with high morbidity and mortality rates. Determining the incidence of acute diarrhea in children and its associated factors is crucial to the planning of preventive approaches. The objective of this study was to determine the incidence of diarrhea and to assess some relevant associated factors to it in children younger than 40 months living in two slums of Salvador, Brazil. This is the first prospective cohort, community-based study that was performed in two periurban slums of Salvador, Brazil. Eighty-four children younger than 40 months were randomly selected and visited every other day for one year. The chi-square test was used to evaluate the occurrence of diarrhea and its associated factors. During the surveillance period, 232 diarrhea episodes were identified, resulting in an incidence rate of 2.8 episodes/child/year. In average (mean value of 84 children,each child suffered 11.1 days of diarrhea per year, yielding an average duration of 3.9 days per episode. The highest incidence rates were found among children under one year old. Early weaning, male sex, malnutrition, having a mother younger than 25 years or who considered her child malnourished, missed immunizations and previous pneumonia were associated factors for suffering diarrheal episodes. The rates of incidence and duration of diarrhea that we found are in accordance to those reported by others. Additionally, our results reinforce the importance of environmental and health-related associated factors to the onset of diarrhea.

    As mast cells have been highlighted in the pathogenesis of diarrhea-predominant irritable bowel syndrome, a new term "mastocytic enterocolitis" was suggested by Jakate and colleagues to describe an increase in mucosal mast cells in patients with chronic intractable diarrhea and favorable response to treatment with antihistamines. Although it is not an established disease entity, two cases have been reported in the English medical literature. Here, for the first time in Asia, we report another case of chronic intractable diarrhea caused by gastrointestinal mastocytosis. The patient was a 70-year-old male with chronic intractable diarrhea for 3 months; the cause of the diarrhea remained obscure even after exhaustive evaluation. However, biopsy specimens from the jejunum were found to have increased mast cell infiltration, and the patient was successfully treated with antihistamines. PMID:27433151

    Purpose: to investigate dosimetric predictors of diarrhea during radiotherapy (RT) for prostate cancer. Patients and methods: all patients who underwent external-beam radiotherapy as part of treatment for localized prostate cancer at the University of Texas Medical Branch, Galveston, TX, USA, from May 2002 to November 2006 were extracted from the own database. From the cumulative dose-volume histogram (DVH), the absolute volumes (V-value) of intestinal cavity (IC) receiving 15, 30, and 45 Gy were extracted for each patient. Acute gastrointestinal toxicity was prospectively scored at each weekly treatment visit according to CTC (common toxicity criteria) v2.0. The endpoint was the development of peak grade {>=} 2 diarrhea during RT. Various patient, tumor, and treatment characteristics were evaluated using logistic regression. Results: 149 patients were included in the analysis, 112 (75.2%) treated with whole-pelvis intensity-modulated radiotherapy (WP-IMRT) and 37 (24.8%) with prostate-only RT, including or not including, the seminal vesicles (PORT {+-} SV). 45 patients (30.2%) developed peak grade {>=} 2 diarrhea during treatment. At univariate analysis, IC-V{sub 15} and IC-V{sub 30}, but not IC-V{sub 45}, were correlated to the endpoint; at multivariate analysis, only IC-V{sub 15} (p = 0.047) along with peak acute proctitis (p = 0.041) was independently correlated with the endpoint. Conclusion: these data provide a novel and prostate treatment-specific ''upper limit'' DVH for IC. (orig.)

    2014-06-21

    A 25-year-old man was admitted with the chief complaints of right flank pain, watery diarrhea, and fever. Blood tests revealed high levels of inflammatory markers, and infectious enteritis was diagnosed. A stool culture obtained on admission revealed no growth of any significant pathogens. Conservative therapy was undertaken with fasting and fluid replacement. On day 2 of admission, the fever resolved, the frequency of defecation reduced, the right flank pain began to subside, and the white blood cell count started to decrease. On hospital day 4, the frequency of diarrhea decreased to approximately 5 times per day, and the right flank pain resolved. However, the patient developed epigastric pain and increased blood levels of the pancreatic enzymes. Abdominal computed tomography revealed mild pancreatic enlargement. Acute pancreatitis was diagnosed, and conservative therapy with fasting and fluid replacement was continued. A day later, the blood levels of the pancreatic enzymes peaked out. On hospital day 7, the patient passed stools with fresh blood, and Campylobacter jejuni/coli was detected by culture. Lower gastrointestinal endoscopy performed on hospital day 8 revealed diffuse aphthae extending from the terminal ileum to the entire colon. Based on the findings, pancreatitis associated with Campylobacter enteritis was diagnosed. In the present case, a possible mechanism of onset of pancreatitis was invasion of the pancreatic duct by Campylobacter and the host immune responses to Campylobacter.

  6. Spatial dynamics of airborne infectious diseases

    2011-01-01

    Disease outbreaks, such as those of Severe Acute Respiratory Syndrome in 2003 and the 2009 pandemic A(H1N1) influenza, have highlighted the potential for airborne transmission in indoor environments. Respirable pathogen-carrying droplets provide a vector for the spatial spread of infection with droplet transport determined by diffusive and convective processes. An epidemiological model describing the spatial dynamics of disease transmission is presented. The effects of an ambient airflow, as an infection control, are incorporated leading to a delay equation, with droplet density dependent on the infectious density at a previous time. It is found that small droplets ($\\sim 0.4\\ \\mu$m) generate a negligible infectious force due to the small viral load and the associated duration they require to transmit infection. In contrast, larger droplets ($\\sim 4\\ \\mu$m) can lead to an infectious wave propagating through a fully susceptible population or a secondary infection outbreak for a localised susceptible population...

  7. Blastocystis hominis and Endolimax nana Co-Infection Resulting in Chronic Diarrhea in an Immunocompetent Male

    2012-06-01

    Full Text Available Blastocystis hominis and Endolimax nana exist as two separate parasitic organisms; however co-infection with the two individual parasites has been well documented. Although often symptomatic in immunocompromised individuals, the pathogenicity of the organisms in immunocompetent subjects causing gastrointestinal symptoms has been debated, with studies revealing mixed results. Clinically, both B. hominis and E. nana infection may result in acute or chronic diarrhea, generalized abdominal pain, nausea, vomiting, flatulence and anorexia. We report the case of a 24-year-old immunocompetent male presenting with chronic diarrhea and abdominal pain secondary to B. hominis and E. nana treated with metronidazole, resulting in symptom resolution and eradication of the organisms. Our case illustrates that clinicians should be cognizant of both B. hominis and E. nana infection as a cause of chronic diarrhea in an immunocompetent host. Such awareness will aid in a timely diagnosis and possible parasitic eradication with resolution of gastrointestinal symptoms.

    In this case report we present in detail the complex nature of enteral feeding, diarrhea, hypoalbuminemia, and edema in a critically ill patient. We also discuss the use of a peptide-elemental formula in this patient, who suffered continuous diarrhea for 15 weeks after liver transplantation. Use of this formula was associated with cessation of the diarrhea and permitted adequate nutritional delivery. After 26 weeks of mechanical pulmonary ventilation, extubation was possible. This case illustrates the ineffectiveness of parenteral albumin infusions for treatment of enteral edema and demonstrates the restoration of normal intestinal absorptive capacity when ultrafiltration was instituted and the patient's generalized edematous state was corrected.

  13. Probiotics and Antibiotic-Associated Diarrhea and Clostridium difficile Infection

    Science.gov (United States)

    Surawicz, Christina M.

    Diarrhea is a common side effect of antibiotics. Antibiotics can cause diarrhea in 5-25% of individuals who take them but its occurrence is unpredictable. Diarrhea due to antibiotics is called antibiotic-associated diarrhea (AAD). Diarrhea may be mild and resolve when antibiotics are discontinued, or it may be more severe. The most severe form of AAD is caused by overgrowth of Clostridium difficile which can cause severe diarrhea, colitis, pseudomembranous colitis, or even fatal toxic megacolon. Rates of diarrhea vary with the specific antibiotic as well as with the individual susceptibility.

    Rotavirus is a leading cause of dehydrating diarrhea and death among infants and children globally, particularly in communities of the developing world. While numerous studies have described the complex relationships among infectious diarrhea, growth faltering, and poverty, the impact of nutritional status on susceptibility to rotavirus diarrhea is not well understood. In a longitudinal study conducted over the first 3 years of life among 626 slum-dwelling infants enrolled at birth in Dhaka, Bangladesh, we observed that common measures of healthy growth and development were positively associated with a risk of symptomatic rotavirus infection. This finding runs counter to the idea that improving childhood nutrition will implicitly decrease the incidence of symptomatic infection by enteric pathogens. As childhood nutrition improves worldwide, rotavirus infection may remain a public health challenge, making universal vaccination of even greater importance. PMID:27510830

    Full Text Available Clostridium difficile-associated diarrhea (CDAD has been recognized as the leading cause of diarrhea worldwide. In the last five years, it has become the leading cause of diarrhea in the Clinical Center of Vojvodina (CCV as well. The aim of this study was to determine the epidemiology and total cost of treatment for all patients with Clostridium difficile-associated diarrhea hospitalized at the Infectious Disease Clinic of the CCV; to analyze the costs of treatment with regard to therapeutic approach; to compare the costs of treatment in each year of the investigated period related to the number of patients, and to analyze the outcome of treatment. The study was retrospective, and the data were collected from the medical records of 472 patients with Clostridium difficile diarrhea treated from 2008 to 2012 and analyzed. Of the total 472 patients with CDAD, 54.23% were female and the average age was 65.84. A statistically significant majority of them had been previously treated in other hospitals and a minority in ambulatory settings (395 inpatients vs. 77 outpatients, p=0.000, p<0.05. Of the 395 previously hospitalized patients, most were from the Clinic of Urology of the CCV (58, 14.68%. When comparing therapeutic options, oral vancomycin was significantly more frequently used than other protocols. The average mortality rate during the study period was 6.51%. In this period, total hospital costs related to Clostridium difficile diarrhea in the Infectious Disease Clinic were $636,679.92. Implementation of infection-control measures and a restricted use of antibiotics would result in a great reduction in material costs.

  1. Epidemiology of travelers' diarrhea: current perspectives.

    MacDonald, K L; Cohen, M L

    1986-01-01

    Identification of the characteristics that make certain travelers more likely to develop diarrhea, the most common illness affecting international travelers, can lead to prevention of the illness and to improved understanding of endemic diarrheal disease in developing countries. Travelers' diarrhea, a syndrome with a spectrum of clinical symptoms, is most frequently characterized by watery diarrhea, cramps, and nausea. The highest attack rates have been reported in travelers from the United States or northern Europe to less-developed, particularly tropical, countries. Among travelers from less-developed countries, diarrhea has been correlated with higher socioeconomic status. The findings that country of origin and socioeconomic status may affect the frequency of previous exposures to enteric pathogens suggest that persons with prolonged exposure acquire immunity and are at lower risk of developing travelers' diarrhea. Although few studies have shown a clear correlation between the eating of specific foods and the development of travelers' diarrhea, the syndrome has been associated with eating in public places.

    Full Text Available Objectives : This research examined about dietary therapy on the diarrhea based on the literary findings, for clinical treatment and prevention of the diarrhea. Methods : This Research examined on histories, compositions, applications, and effects of the diarrhea on about 100 cases of dietary therapy of the diarrhea from recent Chinese literatures Results : 1. Various vegetables, animals and mineral materials including herbs, grains, vegetables, fruits, food and drink were used for the dietary therapy. 2. Methods of the preparation for use as therapeutics were decoction, pulvis, gruel, medicinal wine, cake, tea, paste and gelatin and etc. 3. Frequently used materials were sesame oil, honey, ear mushroom, shiitake mushroom, kelp, walnut seed, hemp seed, groundnut, glutinous rice, apricot stone, yellow bean peel, radish, potato, spinage, and spring onion. Conclusion : Though dietary therapy for the diarrhea is not based on clinical or experimental data, but through experience. It is mostly based on Yin-Yang and five elements, visceral manifestation, channels and their collateral channels and chinese herbal medicine theories. If we use them properly according to oriental medicine method, it will be effective on treating and preventing the diarrhea.

The first group was injected with IBRV-LNM attenuated vaccine strain,one weeks later each animal was inoculated with BVDV-SM attenuated vaccine strain. The second group was only inoculated with BVDV-SM attenuated vaccine strain at the same time with the first group. The third group was the control group and inoculated with MDBK cell culture fluid, the determination of BVDV antibody titer post-vaccination every week until 28 days,and then challenged with BVDV-JL virulent strain. The results showed that the serum of bovine viral diarrhea virus antibody levels had no significant differences between the first and the second group, and observation after the challenge showed that the vaccine effectively protected calves from the challenge. This suggested that IBRV attenuated strain was not restrained BVDV attenuated vaccine virus in vivo.

    Full Text Available Infectious causes should always be considered in all patients with uveitis and it should be ruled out first. The differential diagnosis includes multiple well-known diseases including herpes, syphilis, toxoplasmosis, tuberculosis, bartonellosis, Lyme disease, and others. However, clinicians should be aware of emerging infectious agents as potential causes of systemic illness and also intraocular inflammation. Air travel, immigration, and globalization of business have overturned traditional pattern of geographic distribution of infectious diseases, and therefore one should work locally but think globally, though it is not possible always. This review recapitulates the systemic and ocular mainfestations of several emergent infectious diseases relevant to the ophthalmologist including Rickettsioses, West Nile virus infection, Rift valley fever, dengue fever, and chikungunya. Retinitis, chorioretinitis, retinal vasculitis, and optic nerve involvement have been associated with these emergent infectious diseases. The diagnosis of any of these infections is usually based on pattern of uveitis, systemic symptoms and signs, and specific epidemiological data and confirmed by detection of specific antibody in serum. A systematic ocular examination, showing fairly typical fundus findings, may help in establishing an early clinical diagnosis, which allows prompt, appropriate management.

The sample was constituted by the families registered in the cadaster of the Family Health Program. It was evidenced that the social-economic-cultural aspects had influenced in the diarrhea occurrence, therefore how the lesser mother’s age and the scholarship, bigger the illness prevalence. This population lives in an occupation area, without basic sanitation, with garbage and dejections in opened sky, being below of the poverty boundary. About precocious weaning, water and tea were introduced in the first fifteen days and ar tificial milk during the first month, there was a resistance to use oral rehydrating therapy. They used domestic treatment. It concludes that reversion of structural factors, is necessary and cultural matters should be included in educational activities of a public care policy.

    2015-12-01

    Dynamic models of infectious disease systems abound and are used to study the epidemiological characteristics of disease outbreaks, the ecological mechanisms affecting transmission, and the suitability of various control and intervention strategies. The dynamics of disease transmission are non-linear and consequently difficult to forecast. Here, we describe combined model-inference frameworks developed for the prediction of infectious diseases. We show that accurate and reliable predictions of seasonal influenza outbreaks can be made using a mathematical model representing population-level influenza transmission dynamics that has been recursively optimized using ensemble data assimilation techniques and real-time estimates of influenza incidence. Operational real-time forecasts of influenza and other infectious diseases have been and are currently being generated.

    2008-02-01

    Full Text Available Abstract Syndromic diarrhea (SD, also known as phenotypic diarrhea (PD or tricho-hepato-enteric syndrome (THE, is a congenital enteropathy presenting with early-onset of severe diarrhea requiring parenteral nutrition (PN. To date, no epidemiological data are available. The estimated prevalence is approximately 1/300,000–400,000 live births in Western Europe. Ethnic origin does not appear to be associated with SD. Infants are born small for gestational age and present with facial dysmorphism including prominent forehead and cheeks, broad nasal root and hypertelorism. Hairs are woolly, easily removed and poorly pigmented. Severe and persistent diarrhea starts within the first 6 months of life (≤ 1 month in most cases and is accompanied by severe malabsorption leading to early and relentless protein energy malnutrition with failure to thrive. Liver disease affects about half of patients with extensive fibrosis or cirrhosis. There is currently no specific biochemical profile, though a functional T-cell immune deficiency with defective antibody production was reported. Microscopic analysis of the hair show twisted hair (pili torti, aniso- and poilkilotrichosis, and trichorrhexis nodosa. Histopathological analysis of small intestine biopsy shows non-specific villous atrophy with low or no mononuclear cell infiltration of the lamina propria, and no specific histological abnormalities involving the epithelium. The etiology remains unknown. The frequent association of the disorder with parental consanguinity and/or affected siblings suggests a genetic origin with an autosomal recessive mode of transmission. Early management consists of total PN. Some infants have a rather milder phenotype with partial PN dependency or require only enteral feeding. Prognosis of this syndrome is poor, but most patients now survive, and about half of the patients may be weaned from PN at adolescence, but experience failure to thrive and final short stature.

    2014-02-01

    Modern infectious disease epidemiology has a strong history of using mathematics both for prediction and to gain a deeper understanding. However the study of infectious diseases is a highly interdisciplinary subject requiring insights from multiple disciplines, in particular a biological knowledge of the pathogen, a statistical description of the available data and a mathematical framework for prediction. Here we begin with the basic building blocks of infectious disease epidemiology—the SIS and SIR type models—before considering the progress that has been made over the recent decades and the challenges that lie ahead. Throughout we focus on the understanding that can be developed from relatively simple models, although accurate prediction will inevitably require far greater complexity beyond the scope of this review. In particular, we focus on three critical aspects of infectious disease models that we feel fundamentally shape their dynamics: heterogeneously structured populations, stochasticity and spatial structure. Throughout we relate the mathematical models and their results to a variety of real-world problems.

    2006-03-01

    Antibiotic-associated diarrhea is a common clinical problem occurring in up to 25% of patients, with diarrhea owing to Clostridium difficile accounting for up to a quarter of cases. The clinical and economic costs of antibiotic-associated diarrhea are significant and better treatments are needed. Probiotics may offer potential effective therapy for antibiotic-associated diarrhea by restoring intestinal microbial balance. A number of different probiotics have been evaluated in the prevention and treatment of antibiotic-associated diarrhea in adults and children, including the nonpathogenic yeast Saccharomyces boulardii and multiple lactic-acid fermenting bacteria such as Lactobacillus rhamnosus GG (LGG). A careful review of the literature supports the efficacy of S. boulardii in the prevention of antibiotic-associated diarrhea recurrent C. difficile infection in adults, whereas LGG is useful in the treatment of antibiotic-associated diarrhea in children. Not enough data exist to currently support the use of other probiotic preparations in these conditions. Although generally safe and well tolerated, both S. boulardii and LGG should be used cautiously in immunocompromised patients. Further study of probiotics, including large, well-designed, randomized controlled dose-ranging trials, comparative trials, and cost-benefit analyses are necessary.

    The role of protozoan parasites in the etiology of diarrhea in calves is highlighted with emphasis on correct diagnosis. In neonatal calves, Cryptosporidium parvum is isolated in more than 44% of the faeces of diarrhetic calves. In calves older than one month, both Eimeria bovis and E. zuernii, and Giardia duodenalis are associated with diarrhea and poor growth. Clinical diagnosis has to be confirmed by examination of host faecal material. Both for C. parvum and G. duodenalis immunological assays are available. Control measures must aim to reduce or prevent oocyst or cyst transmission, by combining management measures, desinfection and chemotherapeutic treatment.

    In the present study enterotoxic and cytotoxic activities of twenty Aeromonas caviae strains were examined. They originated from fecal specimens of patients with acute diarrhea during an outbreak in Brazil in 2004. Culture supernatants of fourteen strains (70%) caused fluid accumulation in rabbit ileal intestinal loops and in suckling mice assays, and also showed a cytotoxic activity in Vero and Caco-2 cells. The enterotoxic and cytotoxic factors were heat-stable after culture supernatants treatment at 100 ºC. The results revealed that A. caviae strains produce a putative diarrheagenic virulence factor, a heat-stable cytotoxic enterotoxin that could be linked to the diarrhea outbreak that took place in Brazil.

    Full Text Available We identified different diarrheagenic (DEC Escherichia coli pathotypes isolated from 1,207 children with and without acute endemic diarrhea in Salvador, Bahia, Brazil collected as part of a case-control study. Since the identification of DEC cannot be based on only biochemical and culture criteria, we used a multiplex polymerase chain reaction developed by combining five specific primer pairs for Enteropathogenic Escherichia coli (EPEC, Shiga toxin-producing E. coli/ Enterohaemorrhagic E. coli (STEC/EHEC, Enterotoxigenic E. coli (ETEC and Enteroaggregative E. coli (EAEC to detect these pathotypes simultaneously in a single-step reaction. In order to distinguish typical and atypical EPEC strains, these were tested for the presence of EAF plasmid. The prevalence of diarrheagenic E. coli in this sample of a global case-control study was 25.4% (259 patients and 18.7% (35 patients in the diarrhea group (1,020 patients and the control group (187 patients, respectively. The most frequently isolated pathotype was EAEC (10.7%, followed by atypical EPEC (9.4%, ETEC (3.7%, and STEC (0.6%. Typical EPEC was detected only in one sample. The prevalence of the pathotypes studied in children with diarrhea was not significantly different from that in children without diarrhea.

    Neuroblastoma (NB) is the most common extracranial solid tumor in children. Diarrheal NB is quite rare and is not easy to diagnose in the early stage. Six cases of diarrheal NB in our hospital treated from 1996 to 2006 were retrospectively analyzed, including characteristics such as electrolyte imbalance, pathologic features, vasoactive intestinal peptide (VIP) immunohistochemical staining results, treatment, and prognosis. All patients were boys with 3-8 loose or watery stools each day and routine fecal tests were normal. Abdominal tumors were identified by B-ultrasound. Drugs were ineffective. Three patients underwent surgery, and the remaining three patients received surgery and chemotherapy. Diarrhea stopped after treatment in five patients. Two patients died due to intractable hypokalemia. The tumor was located in the adrenal gland in four patients, in the upper retroperitoneum in one patient, and in the presacral area in one patient. Pathologic findings were NB and ganglioneuroblastoma. Five patients were at clinical stage I-II, and one was at stage III. Four patients survived (followed-up for 6 mo to 4 years). Immunohistochemical staining for VIP was positive. Refractory diarrhea is a paraneoplastic syndrome of NB and is rare. Patients aged 1-3 years who present with chronic intractable diarrhea should be followed closely. Intractable diarrhea, hypokalemia, and dysplasia are the initial clinical manifestations. Increased VIP is characteristic of this disease. Potassium supplementation plays a vital role in the treatment procedure, especially preoperatively. The prognosis of diarrheal NB is good following appropriate treatment.

    Objective: To determine the frequency and clinical features of Rota virus diarrhea in children presenting in a tertiary care hospital. Study Design: A cross-sectional, observational study. Place and Duration of Study: National Institute of Child Health, Karachi, from January to June 2007. Methodology: A total of three hundred children of either gender aged 1 month to 5 years, who presented with diarrhea of < 7 days as a primary illness were enrolled. Children with bloody diarrhea or nosocomial gastroenteritis acquired during hospitalization for other disease were not included. Detection of Rota virus in stool was done by enzyme linked immunoassay. Results: Out of 300 children, 188 (63%) tested positive and 112 (37%) tested negative for Rota virus. Positive Rota virus cases in 7 - 12 months of age was (n = 34, 18.08%). Overall, 151 (80.3%) children with Rota virus were less than 3 years old. 182 (60.7%) had fever, 118 (39.3%) had vomiting and 156 (82.9%) children had both fever and vomiting. Conclusion: This study shows that Rota virus is a common organism causing diarrhea in children less than 3 years of age. There is a need to incorporate Rota virus vaccine in the national EPI program to decrease the disease burden as highlighted in this study. (author)

    2013-06-01

    Full Text Available Bovine viral diarrhea is a widespread infection of cattle that has a wide range of clinical symptoms in domestic and wild ruminants. It is a major problem in cattle and causes significant economic losses in the cattle industry. The virus infects bovines of all ages and causes both immunosuppression and reproductive, respiratory and digestive disorders. Persistently infected cattle are the main factor in transmission of the disease between and among herds. Comparative results of antibodies presence received by two methods of enzymoimmunoassay and virus neutralization test are given in the paper. During the work, 1010 samples of blood serum of cattle from three farms in the Kharkiv region were selected and analyzed. Bovine viral diarrhea virus concerning antibodies were found by enzymoimmunoassay in 704 samples (69.7% using commercial kit and in 690 samples (68.3% using in house method. After results clarification by virus neutralization test, bovine viral diarrhea antibodies were found in 712 samples (70.5%. Immunoenzyme analysis is recommended for mass screening of cattle for viral diarrhea occurrence. The results confirm that the sensitivity immunoenzyme analysis satisfies the requirements of the diagnostic methods. Using the neutralization reaction of viruses as the «gold standard» of serological methods, it is appropriate to clarify the results of immunoenzyme analysis. Since the results contain a signi ficant number of false positive results, it is necessary to carry out comprehensive studies using both serological and molecular genetics methods.

    Chronic enterocolitis is the leading cause of morbidity in colonies of captive rhesus macaques (Macaca mulatta). This study's aim was to identify the common enteric pathogens frequently associated with chronic enterocolitis in normal, immunocompetent rhesus monkeys and to elucidate the influence of this clinical syndrome on the host immune system. We analyzed the fecal specimens from 100 rhesus macaques with or without clinical symptoms of chronic diarrhea. Retrospective analysis revealed an increased incidence of Campylobacter spp. (Campylobacter coli and Campylobacter jejuni), Shigella flexneri, Yersinia enterocolitica, adenovirus, and Strongyloides fulleborni in samples collected from animals with chronic diarrhea (P coli, carrying the eaeA intimin or Stx2c Shiga toxin virulence genes, Balantidium coli, Giardia lamblia, Enterocytozoon bieneusi, and Trichuris trichiura was found in all animals regardless of whether diarrhea was present. In addition, the upregulation of interleukin-1 alpha (IL-1 alpha), IL-3, and tumor necrosis factor alpha cytokine genes, accompanied by an increased presence of activated (CD4(+) CD69(+)) T lymphocytes was found in gut-associated lymphoid tissues collected from animals with chronic enterocolitis and diarrhea in comparison with clinically healthy controls (P < 0.05). These data indicate that chronic enterocolitis and diarrhea are associated, in part, with a variety of enteric pathogens and highlight the importance of defining the microbiological status of nonhuman primates used for infectious disease studies. The data also suggest that chronic colitis in rhesus macaques may have potential as a model of inflammatory bowel disease in humans. PMID:12819098

    AIM: To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes,osmotic gap and pH.METHODS: Seventy-six patients were included: 51 with microscopic colitis (MC) [40 with lymphocytic colitis (LC);11 with collagenous colitis (CC)]; 7 with MC without diarrhea and 18 as a control group (CG). They collected stool for 3 d. Sodium and potassium concentration were determined by flame photometry and chloride concentration by titration method of Schales. Fecal osmotic gap was calculated from the difference of osmolarity of fecal fluid and double sum of sodium and potassium concentration.RESULTS: Fecal fluid sodium concentration was significantly increased in LC 58.11±5.38 mmol/L (P<0.01)and CC 54.14±8.42 mmol/L (P<0.05) than in CG 34.28±2.98 mmol/L. Potassium concentration in LC 74.65±5.29 mmol/L (P<0.01) and CC 75.53±8.78 mmol/L (P<0.05) was significantly less compared to CG 92.67±2.99 mmol/L.Chloride concentration in CC 36.07±7.29 mmol/L was significantly higher than in CG 24.11±2.05 mmol/L (P<0.05).Forty-four (86.7%) patients had a secretory diarrhea compared to fecal osmotic gap. Seven (13.3%) patients had osmotic diarrhea.CONCLUSION: Diarrhea in MC mostly belongs to the secretory type. The major pathophysiological mechanism in LC could be explained by a decrease of active sodium absorption. In CC, decreased Cl/HCO3 exchange rate and increased chloride secretion are coexistent pathways.

    Background and Objectives: Enteroinvasive Escherichia coli (EIEC) is one the cause of acute diarrhea and bacillary dysentery in developing countries. Routine diagnostic microbiology tests are not capable to distinguish EIEC from other pathogenic or non-pathogenic E. coli. PCR, targeting ipaH, virF, virB and other virulence genes, is a diagnostic method for detecting E. coli pathotypes. Using PCR, we identified EIEC by PCR targeting ipaH and virF genes among E.coli isolates from patients with diarrhea at the selected hospitals in Tehran. Materials and Methods: Isolates of E. coli were cultured from 140 specimens of patients with diarrhea using culture and IMViC test. DNA was extracted using commercial kits and and tested for uidA, ipaH and virF genes by PCR. Results: Totally, 140 E. coli isolates were confirmed by IMViC tests and PCR targeting uidA gene. Of 140 E. coli isolates, 5 (3.6%) were positive for the ipaH gene, 4 (2.9%) contained virF gene and 4 (2.9%) were positive for both ipaH and virF genes. Conclusion: These results indicated that EIEC is a considerable acute diarrheagenic pathogen in adults and infants. Moreover, virF gene is suggested for evaluation of invasiveness of EIEC.

    Full Text Available On the territory of the Russian Federation in the overall structure of acute intestinal infections the proportion of viral diarrhea among children varies from 24 to 78% of cases depending on the season. The acute viral intestinal infections etiological confirmation is performed mainly among patients of infectious hospitals. The prevalence of viral acute intestinal infections in non-infectious hospitals, including infections associated with medical care, remains unclear. Currently estimation of viral component in the acute intestinal infections overall structure mainly consists in determination of rotavirus infection prevalence excluding other pathogens. As the part of viral etiology hospital infections epidemiological surveillance in non-infections children’s hospital the study of acute viral intestinal infections etiological structure and molecular genetics characterization of identified enteric viruses is conducted. The syndrome diagnosis of acute intestinal infections cases was introduced — an identification and evaluation of patients with signs of dysfunction of the gastrointestinal tract, that is not related to the underlying disease. A set of laboratory methods included identification of various intestinal pathogens DNA (RNA by PCR-RT method; genotyping of enteric viruses using sequencing; nucleotide sequence analysis of cDNA fragments using the BLAST software package for identification of closely related strains and an online service for automatic genotyping of noroviruses by Norovirus Genotyping Tool Version 1.0. Alignment of nucleotide sequences and phylogenetic analysis was performed using the software MEGA 5.0. The obtained sequence fragments of the genome was downloaded in GenBank international database. The use of molecular genetics research methods allowed to differentiate viral pathogens of acute intestinal infections and to establish the fact of nosocomial transmission.

    Full Text Available Calf diarrhea is an important disease that occurs in association with the interaction of various infectious agents and calf susceptibility. The economic losses is associated with death loss and treatment costs, reduction of live weight gain, and reduction of productive life span, which may be considerable. Thyroid hormones previously thought mainly in thermoregulation and energy metabolism. Recently, several studies have challenged on their roles in the metabolic response of animals to certain conditions such as nutritional, environmental, or disease state. The aim of the present study was to survey relationships between thyroid hormones in calves with diarrhea in the different clinical features. Holstein calves (50 within 1 day to 2 months old with signs of diarrhea and healthy calves (40 with similar age and sex were selected. Standard clinical examinations and also dehydration degree assessment were carried out on each calf and recorded accordingly. Calves with clinical signs of diarrhea were divided in different groups based on the severity of the clinical findings, fever and degree of dehydration. Blood samples were taken from the jugular vein from all calves into vacutainer tubes for serum collection.T4, fT4, T3 and fT3 concentrations were measured by validated methods. A significant increase in T4, T3 and fT3 in diarrheic calves was observed (P<0.05. Thyroid hormones in calves with severe clinical signs decreased significantly (P<0.001 compared to calves with moderate or mild systemic clinical signs. Thyroid hormones between febrile diarrheic calves compared to afebrile diarrheic calves had no significant changes. Diarrheic calves with severe dehydration compared to diarrheic calves with mild and moderate dehydration had significant decreases in their thyroid hormones (P<0.001.

  2. Mycotic and other nonbacterial infectious diseases

    International Nuclear Information System (INIS)

    The infectious diseases discussed in this chapter are caused by a variety of organisms, many of which are capable of producing acute, fulminating, generalized disease in which there is associated involvement of the lungs. These organisms may also cause disease, usually chronic, limited primarily to the lungs. Some of the organisms are saprophytes or of very low virulence, but in compromised hosts they may produce life-threatening acute pneumonias. The diseases must be differentiated from each other as well as from pulmonary tuberculosis and occasionally from lung tumor. The ultimate diagnosis depends upon demonstration of the causative agent in bronchial secretions or in sections of the lung. In some instances bacteriologic studies based on immunologic reactions are sufficient. These consist of skin tests, agglutination, complement fixation, and precipitation reactions

    @@ Infantile diarrhea is a common disease in babies of less than 2 years old in summer or autumn. It is due to acute dyspepsia mainly caused by improper feeding or attack of cold or damp pathogens.Clinically, it is characterized by increased times of defecation (5-6, or even dozens of times a day),yellow-green or blue-green thin feces intermingled with mucus, milk-mass and indigested food which have a sour and fetid odor, accompanied with loss of appetite, abdominal distending pain, nausea,vomiting, and even fever, irritability, dehydration and electrolyte disturbance in severe cases. The microscopy reveals that there are leukocytes and fat globules in feces. We have treated 60 cases of infantile diarrhea with acupuncture and He-Ne laser point irradiation and obtained satisfactory therapeutic results.

    2010-09-01

    Full Text Available Acute gastroenteritis is one of the most common infectious diseases of childhood. Its symptoms are vomiting, diarrhea, and dehydration. In the emergency ward, intravenous rather than oral rehydration is usually preferred because of the high likelihood of emesis. Treatments to reduce emesis are of value in improving the rehydration procedure. Our study is a double-blind randomized trial and proposes the use of ondansetron as an anti-emetic drug to treat children with acute gastroenteritis. Seventy-four in-patients, aged 3 months to 15 years, were enrolled and randomly assigned to an ondansetron or placebo group. Inclusion criteria were the diagnosis of acute gastroenteritis and the absence of other diseases or allergies to drugs. A single bolus (0.15 mg/kg of ondansetron was injected intravenously; normal 0.9% saline solution was used as a placebo. This treatment induced vomiting cessation in the ondansetron group significantly in comparison to the placebo group. The length of the hospital stay and the oral rehydration fluid volume were similar in the two groups and no adverse effects were noticed. Thus, safety, low cost, and overall bene­fit of ondansetron treatment suggests that this drug can be administered successfully to children with acute gastroenteritis.

    Developing countries face a huge burden of infectious diseases, a number of which co-exist. This paper estimates the pattern and variation of malaria and diarrhea coexistence in Chikhwawa, a district in Southern Malawi using bivariate multilevel modelling with Bayesian estimation. A probit link was employed to examine hierarchically built data from a survey of individuals (n = 6,727) nested within households (n = 1,380) nested within communities (n = 33). Results show significant malaria [σ²μ₁=0.901 (95% CI:0.746,1.056)] and diarrhea [σ²μ₂=1.009 (95% CI:0.860,1.158)] variations with a strong correlation between them [r(¹,²)μ=0.565] at household level. There are significant malaria [σ²ν₁=0.053 (95% CI: 0.018,0.088)] and diarrhea [σ²ν₂=0.099(95% CI : 0.030,0.168) ] variations at community level but with a small correlation [r(¹,²) ν=0.124] between them. There is also significant correlation between malaria and diarrhea at individual level [ r(¹,²) e=0.241]. These results suggest a close association between reported malaria-like illness and diarrheal illness especially at household and individual levels in Southern Malawi. PMID:26197332

    Full Text Available Acute appendicitis is more common in school-age children, but it rarely occurs in infants. The younger the patient, the fastest the course of the disease. In addition, there are greater risks of complications. A case of a nine-month-old infant, admitted to the pediatric hospital with fever and diarrhea, is presented. After several tests, he underwent surgery. Peritonitis caused by acute gangrenous appendicitis was diagnosed. While the patient was in the intensive care unit, he suffered a septic shock and acute multiple organ failure. As a result, he died 24 hours later. The biopsy confirmed the diagnosis of acute gangrenous appendicitis. Acute appendicitis is a disease that must be considered by doctors who treat infants with fever, diarrhea and abdominal pain related to irritability. Thus, an early diagnosis of the disease as well as the implementation of an appropriate surgical treatment can be performed.

    Feline infectious peritonitis (FIP) frequently results in death in cats. It is caused by a mutated, highly contagious coronavirus, and it is more common in indoor cats in multicat households. A complex interaction between the coronavirus and the feline immune system causes disseminated vasculitis, which is the hallmark of FIP. New tests are being developed, but the antemortem diagnosis of FIP continues to be difficult and frustrating. Current treatments are crude and involve supportive care and immunosuppression. Minimizing exposure is the best method of preventing infection.

    This article discusses the nature of the health challenges created by globalization and proposes new forms of international cooperation to confront them. The discussion of global health challenges includes both the transfer of health risks, with an emphasis on infectious diseases, and the international dissemination of health opportunities, including the transfer of knowledge and technology. The authors argue that the health-related challenges and opportunities of an increasingly interdependent world demand new forms of international cooperation. The authors suggest the promotion of 3 elements that, in their essence, contain the idea of collaboration: exchange, evidence, and empathy.

    The maintenance of transplantation tolerance induced in adult mice after short-term treatment with nonlytic monoclonal antibodies to CD4 and CD8 was investigated. CD4^+ T cells from tolerant mice disabled naive lymphocytes so that they too could not reject the graft. The naive lymphocytes that had been so disabled also became tolerant and, in turn, developed the capacity to specifically disable other naive lymphocytes. This process of "infectious" tolerance explains why no further immunosuppression was needed to maintain long-term transplantation tolerance.

    Acute pancreatitis is the most common gastro-intestinal indication for acute hospitalization and its incidence continues to rise. In severe pancreatitis, morbidity and mortality remains high and is mainly driven by organ failure and infectious complications. Early management strategies should aim to prevent or treat organ failure and to reduce infectious complications. This review addresses the management of acute pancreatitis in the first hours to days after onset of symptoms, including fluid therapy, nutrition and endoscopic retrograde cholangiography. This review also discusses the recently revised Atlanta classification which provides new uniform terminology, thereby facilitating communication regarding severity and complications of pancreatitis.

    In order to counter the common perception that molecular diagnostics are too complicated to work in low resource settings, we have performed a difficult sample preparation and DNA amplification protocol using instrumentation designed to be operated without wall or battery power. In this work we have combined a nearly electricity-free nucleic acid extraction process with an electricity-free isothermal amplification assay to detect the presence of Clostridium difficile (C. difficile) DNA in the stool of infected patients. We used helicase-dependent isothermal amplification (HDA) to amplify the DNA in a low-cost, thermoplastic reaction chip heated with a pair of commercially available toe warmers, while using a simple Styrofoam insulator. DNA was extracted from known positive and negative stool samples. The DNA extraction protocol utilized an air pressure driven solid phase extraction device run using a standard bicycle pump. The simple heater setup required no electricity or battery and was capable of maintaining the temperature at 65°C±2°C for 55 min, suitable for repeatable HDA amplification. Experiments were performed to explore the adaptability of the system for use in a range of ambient conditions. When compared to a traditional centrifuge extraction protocol and a laboratory thermocycler, this disposable, no power platform achieved approximately the same lower limit of detection (1.25×10(-2) pg of C. difficile DNA) while requiring much less raw material and a fraction of the lab infrastructure and cost. This proof of concept study could greatly impact the accessibility of molecular assays for applications in global health.

  18. Mitigating Infectious Disease Outbreaks

    Science.gov (United States)

    Davey, Victoria

    The emergence of new, transmissible infections poses a significant threat to human populations. As the 2009 novel influenza A/H1N1 pandemic and the 2014-2015 Ebola epidemic demonstrate, we have observed the effects of rapid spread of illness in non-immune populations and experienced disturbing uncertainty about future potential for human suffering and societal disruption. Clinical and epidemiologic characteristics of a newly emerged infectious organism are usually gathered in retrospect as the outbreak evolves and affects populations. Knowledge of potential effects of outbreaks and epidemics and most importantly, mitigation at community, regional, national and global levels is needed to inform policy that will prepare and protect people. Study of possible outcomes of evolving epidemics and application of mitigation strategies is not possible in observational or experimental research designs, but computational modeling allows conduct of `virtual' experiments. Results of well-designed computer simulations can aid in the selection and implementation of strategies that limit illness and death, and maintain systems of healthcare and other critical resources that are vital to public protection.

    Viral studies were carried out on throat swabs, rectal swabs and washed white blood cells from 27 cases of infectious mononucleosis (positive Paul-Bunnell-David-sohn test), and from 22 controls. Four cytopathic agents were isolated in the test group, two of which were readily subcultured for at least three successive passages. Three cytopathic agents were recovered in the control group, two of which have been identified as adenovirus type 5 and adenovirus type 3. The unidentified agents tested so far are sensitive to ether and to pH 3. The results of acridine-orange staining and the immunofluorescence technique, using a conjugated control serum and two conjugated convalescent infectious mononucleosis sera, indicate that the isolated agent or agents in the test group are RNA-type agents with a cytoplasmic cycle of development. The overall results of this study lead the authors to suspect a respiratory syncytial-like myxovirus as the as yet unidentified agent which they recovered.

    Traveler's diarrhea is a very common condition that affects approximately 12 million subjects each year. This disorder is benign but nevertheless interferes with the traveler's plans in 40% of cases. Several drugs have been used for prophylaxis, in association with appropriate precautions concerning food and drink. Trimethoprim-sulfamethoxazole and cyclines are effective but may induce adverse effects. Nifuroxazide in a dose of 400 mg each day throughout the trip has proved effective. Tolerance was outstanding with no adverse effects. PMID:3534765

    AIM: Clostridium difficile infection is primarily a nosocomial infection but asymptomatic carriers of Clostridium difficile can be found in up to 5% of the general population.Ampicillin, cephalosporins and clindamycin are the antibiotics that are most frequently associated with Clostridium difficile-associated diarrhea or colitis. Little is known about acute renal failure as a consequence of Clostridium difficile-associated diarrhea.METHODS: In this case report, we describe the course of Clostridium difficile-associated diarrhea in an 82-yearold patient developing acute renal failure. Stopping the offending agent and symptomatic therapy brought a rapid improvement of diarrhea and acute renal failure, full recovery was gained 18 d after admission. In a systematic review we looked for links between the two conditions.RESULTS: The link between Clostridium difficilr-associated diarrhea and acute renal failure in our patient was most likely volume depletion. However, in experimental studies a direct influence of Clostridium difficile toxins on renal duct cells could be shown.CONCLUSION: Rapid diagnosis, nonspecific supportive treatment and specific antibiotic treatment, especially in the elderly, may lower excess mortality Clostridium difficile-associated diarrhea and renal failure being possible complications.

  2. Bile Acid Diarrhea: Prevalence, Pathogenesis, and Therapy

    Science.gov (United States)

    Camilleri, Michael

    2015-01-01

    Bile acid diarrhea (BAD) is usually seen in patients with ileal Crohn’s disease or ileal resection. However, 25% to 50% of patients with functional diarrhea or diarrhea-predominant irritable bowel syndrome (IBS-D) also have evidence of BAD. It is estimated that 1% of the population may have BAD. The causes of BAD include a deficiency in fibroblast growth factor 19 (FGF-19), a hormone produced in enterocytes that regulates hepatic bile acid (BA) synthesis. Other potential causes include genetic variations that affect the proteins involved in BA enterohepatic circulation and synthesis or in the TGR5 receptor that mediates the actions of BA in colonic secretion and motility. BAs enhance mucosal permeability, induce water and electrolyte secretion, and accelerate colonic transit partly by stimulating propulsive high-amplitude colonic contractions. There is an increased proportion of primary BAs in the stool of patients with IBS-D, and some changes in the fecal microbiome have been described. There are several methods of diagnosing BAD, such as 75selenium homotaurocholic acid test retention, serum C4, FGF-19, and fecal BA measurement; presently, therapeutic trials with BA sequestrants are most commonly used for diagnosis. Management involves the use of BA sequestrants including cholestyramine, colestipol, and colesevelam. FXR agonists such as obeticholic acid constitute a promising new approach to treating BAD.

    To eliminate cytotoxic effects of colostrum on cells, a modified virus neutralization test (VNT) for the detection of Bovine viral diarrhea virus-specific neutralizing antibodies in colostrum was developed. The new test was compared to the World Organization for Animal Health-recommended VNT and the results evaluated. The agreement of the new test compared to the standard VNT was determined to be 98%, whereas sensitivity and specificity of the modified VNT compared to the standard VNT were 100%. Bovine viral diarrhea virus-specific antibodies were detected in 42 sera samples and 38 colostrum samples. The antibody titers in serum and colostrum showed a high correlation (n = 56, r = 0.9719, P < 0.001). The modified virus neutralization technique described herein succeeds in eliminating cytotoxic effects and can be readily applied for the detection of specific antibodies against other infectious agents in colostrum.

    Full Text Available Introduction & Objective: Diarrheal diseases are considered a major health problem, especially in children. Enteropathogenic Escherichia coli (EPEC strains are the common cause of diarrhea in children especially in developing countries. Because of undesirable effects of diarrhea and its interference with children's growth, in some cases antibiotic treatment is recommended. In recent years, resistance toward common and effective antibiotics in the treatment of infectious diseases became one of the most important challenges in medical society, for this purpose, antibiotic sensitivity and resistance of strains in every geographical zone must be determined. So in this study, of antibiotic patterns of these bacteria were examined.Materials & Methods: This cross-sectional study was performed on 192 strains of Enteropathogen Escherichia coli isolated from children who were suffering from diarrhea in 1389-1390 in the microbiology laboratory of Hamadan University of medical sciences. To identify these strains, standard biochemical and serology tests were used. The antibiotic sensitivity test of these isolates was carried out with disc diffusion agar method according to the CLSI standards for 14 different antibiotics disc. Resistance toward 3 or more than 3 classes of antibiotics were defined as multidrug resistance.Results: The result of this study shows EPEC strains had the highest resistance to cefpodoxime (97%, trimethoprim (60.7%, tetracycline (58.4% and ampicillin (45.8%. Multidrug resistance was 68.7 percent. These strains also showed the highest sensitivity against imipenem, ceftriaxone, and ciprofloxacin antibiotics.Conclusion: EPEC strains that were studied with resistance to ampicillin, tetracycline and convenient sensitivity against fluoroquinolones are one of the major factors in children’s diarrhea. A result of this research suggests that antimicrobial resistance in Escherichia coli strains are high and prescribing and antibiotic is not

    Although the medical complications of sports are usually traumatic in nature, infectious hazards also arise. While blood-borne pathogens such as HIV, hepatitis B, and hepatitis C, cause significant illness, the risk of acquiring these agents during sporting activities is minimal. Skin infections are more commonplace, arising from a variety of microbial agents including bacterial, fungal, and viral pathogens. Sports involving water contact can lead to enteric infections, eye infections, or disseminated infections such as leptospirosis. Mumps, measles, and influenza are vaccine-preventable diseases that have been transmitted during sporting events, both in players and in spectators. Prevention is the key to many of these infections. Players should be vaccinated and should not participate in sports if their infection can be spread by contact, airborne, or droplet transmission.

    Full Text Available There is a historical association between wetlands and infectious disease that has led to the modification of wetlands to prevent disease. At the same time there has been the development of water resources projects that increase the risk of disease. The demand for more water development projects and the increased pressure to make natural wetlands economically beneficial creates the need for an ecological approach to wetland management and health assessment. The environmental and health interactions are many. There is a need to take into account the landscape, spatial boundaries, and cross-boundary interactions in water development projects as well as alternative methods to provide water for human needs. The research challenges that need to be addressed are discussed.

    2003-02-01

    Full Text Available Advanced HIV infection is frequently complicated by diarrhea, disruption of bowel structure and function, and malnutrition. Resulting malabsorption of or pharmacokinetic changes in antiretroviral agents might lead to subtherapeutic drug dosing and treatment failure in individual patients, and could require dose adjustment and/or dietary supplements during periods of diarrheal illness. We determined the plasma levels of antiretroviral medications in patients that had already been started on medication by their physicians in an urban infectious diseases hospital in northeast Brazil. We also obtained blood samples from patients hospitalized for diarrhea or AIDS-associated wasting, and we found reduced stavudine and didanosine levels in comparison with outpatients without diarrhea or wasting who had been treated at the same hospital clinic. There was a predominance of the protozoal pathogens Cryptosporidium and Isospora belli, typical opportunistic pathogens of AIDS-infected humans, in the stool samples of inpatients with diarrhea. We conclude that severe diarrhea and wasting in this population is associated with both protozoal pathogens and subtherapeutic levels of antiretroviral medications.

    Acute diarrhea disease caused by Rotaviruses A (RVA) is still the leading cause of morbidity and mortality in children ≤5 years old in developing countries. An exploratory cross-sectional study was conducted between February and September, 2011 to determine the proportion of acute diarrhea caused by RVA. A total of 254 stool specimens were collected from children ≤5 years old with acute diarrhea, including outpatients (222 children) and inpatients (32 children), in three local health centers in Chókwè District, Gaza Province, South of Mozambique. RVA antigens were detected using enzyme immunoassay (EIA); the RVA G (VP7) and P (VP4) genotypes were determined by RT-PCR or analysis sequencing. Sixty (24%) out of 254 fecal specimens were positive for RVA by EIA; being 58 (97%) from children ≤2 years of age. RVA prevalence peaks in June and July (coldest and drier months) and the G[P] binary combination observed were G12P[8] (57%); G1P[8] (9%); G12P[6] (6%); and 2% for each of the following genotypes: G1P[6], G2P[6] G4P[6], and G9P[8]. Non-Typeable (NT) G and/or P genotypes were observed as follows: G12P [NT] (6%); G1P [NT], G3P[NT] and GNTP[NT] (4%). Considering the different GP combinations, G12 represented 67% of the genotypes. This is the first data showing the diversity of RVA genotypes in Mozambique highlighting the epidemiological importance of these viruses in acute diarrhea cases in children ≤2 years old. In addition, these findings will provide a baseline data before the introduction of the RVA monovalent (Rotarix(®) ) vaccine in the National Immunization Program in September 2015. J. Med.

    2013-01-01

    Full Text Available Abstract Syndromic diarrhea/Tricho-hepato-enteric syndrome (SD/THE is a rare and severe bowel disorder caused by mutation in SKIV2L or in TTC37, 2 genes encoding subunits of the putative human SKI complex. The estimated prevalence is 1/1,000,000 births and the transmission is autosomal recessive. The classical form is characterized by 5 clinical signs: intractable diarrhea of infancy beginning in the first month of life, usually leading to failure to thrive and requiring parenteral nutrition; facial dysmorphism characterised by prominent forehead and cheeks, broad nasal root and hypertelorism; hair abnormalities described as woolly and easily removable; immune disorders resulting from defective antibody production; intrauterine growth restriction. The aetiology is a defect in TTC37, a TPR containing protein, or in the RNA helicase SKIV2L, both constituting the putative human ski complex. The ski complex is a heterotetrameric cofactor of the cytoplasmic RNA exosome which ensures aberrants mRNAs decay. The diagnosis SD/THE is initially based on clinical findings and confirmed by direct sequencing of TTC37 and SKIV2L. Differential diagnosis with the other causes of intractable diarrhea is easily performed by pathologic investigations. During their clinical course, most of the children require parenteral nutrition and often immunoglobulin supplementation. With time, some of them can be weaned off parenteral nutrition and immunoglobulin supplementation. The prognosis depends on the management and is largely related to the occurrence of parenteral nutrition complications or infections. Even with optimal management, most of the children seem to experience failure to thrive and final short stature. Mild mental retardation is observed in half of the cases.

Multiplex PCR panels comprised enteroinvasive bacteria, diarrhea-associated Escherichia coli (EPEC, ETEC, EAEC, and EIEC), enteropathogenic viruses, and protozoa. Noroviruses were characterized by sequencing. Cultural screening for Enterobacteriaceae with extended-spectrum beta-lactamases (ESBL) with subsequent repetitive sequence-based PCR (rep-PCR) typing was performed. Clinical information was assessed. Results. Positive PCR results for diarrhea-associated pathogens were detected in 43/53 samples, comprising EPEC (n = 21), ETEC (n = 19), EAEC (n = 15), Norovirus (n = 10), Shigella spp./EIEC (n = 6), Cryptosporidium parvum (n = 3), Giardia duodenalis (n = 2), Salmonella spp. (n = 1), Astrovirus (n = 1), Rotavirus (n = 1), and Sapovirus (n = 1). ESBL-positive Enterobacteriaceae were grown from 13 out of 48 samples. Simultaneous infections with several enteropathogenic agents were observed in 23 instances. Symptoms were mild to moderate. There were hints of autochthonous transmission. Conclusions. Multiplex real-time PCR proved to be suitable for diarrhea surveillance on deployment. Etiological attribution is challenging in cases of detection of multiple pathogens. PMID:26525953

    Cerebellar involvement by infectious-inflammatory conditions is rare in children. Most patients present with acute ataxia, and are typically previously healthy, young (often preschool) children. Viral involvement is the most common cause and ranges from acute postinfectious ataxia to acute cerebellitis MR imaging plays a crucial role in the evaluation of patients suspected of harboring inflammatory-infectious involvement of the cerebellum and brainstem. Knowledge of the imaging features of these disorders and technical competence on pediatric MR imaging are necessary for a correct interpretation of findings, which in turn prompts further management.

    Rectal swabs from 391 infants less than 18 months of age who were hospitalized with acute diarrhea and from 138 similarly aged healthy infants were examined for the etiologic agents of diarrhea. Aeromonas spp. were recovered from 205 of 391 (52.4%) diarrheic patients, whereas they were recovered from 12 of 138 (8.7%) controls (P less than 10(-11). Among the 205 Aeromonas-positive diarrheic patients, 118 (57.6%) were found to be coinfected with other common enteropathogens. Of the 164 Aeromonas-positive initial diarrheic specimens, 82 (50.0%) had one or more other enteropathogens present; 30 patients were coinfected with rotavirus, 20 with enterotoxigenic Escherichia coli, 16 with Campylobacter spp., 14 with Shigella spp., 13 with enteropathogenic E. coli, 4 with Vibrio spp., 1 with Salmonella spp., and 1 with Plesiomonas spp. of Aeromonas strains from cases compared with that from controls supports an etiologic role for this organism. However, frequent concomitant infections with other well-recognized enteropathogens and a lack of disease correlation with common Aeromonas phenotypes suggest that only a subset of Aeromonas strains may be diarrhea causing and that such strains may be common to several of the existing species.

    Background Effective and safe treatments are needed for patients who have irritable bowel syndrome (IBS) with diarrhea. We conducted two phase 3 trials to assess the efficacy and safety of eluxadoline, a new oral agent with mixed opioid effects (μ- and κ-opioid receptor agonist and δ-opioid receptor antagonist), in patients with IBS with diarrhea. Methods We randomly assigned 2427 adults who had IBS with diarrhea to eluxadoline (at a dose of 75 mg or 100 mg) or placebo twice daily for 26 weeks (IBS-3002 trial) or 52 weeks (IBS-3001 trial). The primary end point was the proportion of patients who had a composite response of decrease in abdominal pain and improvement in stool consistency on the same day for at least 50% of the days from weeks 1 through 12 and from weeks 1 through 26. Results For weeks 1 through 12, more patients in the eluxadoline groups (75 mg and 100 mg) than in the placebo group reached the primary end point (IBS-3001 trial, 23.9% with the 75-mg dose and 25.1% with the 100-mg dose vs. 17.1% with placebo; P=0.01 and P=0.004, respectively; IBS-3002 trial, 28.9% and 29.6%, respectively, vs. 16.2%; P<0.001 for both comparisons). For weeks 1 through 26, the corresponding rates in IBS-3001 were 23.4% and 29.3% versus 19.0% (P=0.11 and P<0.001, respectively), and the corresponding rates in IBS-3002 were 30.4% and 32.7% versus 20.2% (P=0.001 and P<0.001, respectively). The most common adverse events associated with 75 mg of eluxadoline and 100 mg of eluxadoline, as compared with placebo, were nausea (8.1% and 7.5% vs. 5.1%), constipation (7.4% and 8.6% vs. 2.5%), and abdominal pain (5.8% and 7.2% vs. 4.1%). Pancreatitis developed in 5 (2 in the 75-mg group and 3 in the 100-mg group) of the 1666 patients in the safety population (0.3%). Conclusions Eluxadoline is a new therapeutic agent that reduced symptoms of IBS with diarrhea in men and women, with sustained efficacy over 6 months in patients who received the 100-mg dose twice daily.

    AIM: To explore the characteristics of diarrhea caused by acaroid mites.METHODS: Acaroid mites in fresh stools of 241 patients with diarrhea were separated by flotation in saturated saline.Meanwhile, skin prick test, total IgE and mite-specific IgE were detected in all patients.RESULTS: The total positive rate of mites in stool samples of the patients was 17.01% (41/241), the positive rates of mites in male and female patients were 15.86 % (23/145)and 18.75 % (18/96), respectively, without significant difference (P>0.05). The percentage of skin prick test as ″+++″″++ ″″+ ″″±″″-″ was″+++, ″++″,″ +″, ″±″ and ″-″was 9.13 % (22/241), 7.47 %(18/241), 5.81% (14/241), 4.98 % (12/241) and 72.61%(175/241), respectively. The serum levels of total IgE, mitespecific IgE in patients with and without mites in stool samples were (165.72±78.55) IU/ml, (132.44±26.80) IU/ml and (145.22±82.47) IU/ml, (67.35±45.28) IU/ml,respectively, with significant difference (P<0.01). The positive rate of mites in stool samples in staffs working in traditional Chinese medicine storehouses or rice storehouses (experimental group) was 26.74 % (23/86), which was significantly higher than that (11.61%, 18/155) in people engaged in other professions (X2=8.97, P<0.01).CONCLUSION: Acaroid mites cause diarrhea and increase serum levels of total IgE and mite-specific IgE of patients,and the prevalence of diarrhea caused by acaroid mites is associated with occupations rather than the gender of patients.

    2012-01-01

    Natural disasters may lead to infectious disease outbreaks when they result in substantial population displacement and exacerbate synergic risk factors (change in the environment, in human conditions and in the vulnerability to existing pathogens) for disease transmission. We reviewed risk factors and potential infectious diseases resulting from prolonged secondary effects of major natural disasters that occurred from 2000 to 2011. Natural disasters including floods, tsunamis, earthquakes, tropical cyclones (e.g., hurricanes and typhoons) and tornadoes have been secondarily described with the following infectious diseases including diarrheal diseases, acute respiratory infections, malaria, leptospirosis, measles, dengue fever, viral hepatitis, typhoid fever, meningitis, as well as tetanus and cutaneous mucormycosis. Risk assessment is essential in post-disaster situations and the rapid implementation of control measures through re-establishment and improvement of primary healthcare delivery should be given high priority, especially in the absence of pre-disaster surveillance data.

    analyze the results of a stool work-up protocol in a series of infants and preschoolers with acute diarrhea. Material and Methods. A cross-sectional descriptive study was conducted between April 1999 and March 2000, among 288 children seen at a pediatric office in Guadalajara, Mexico. The mean age (±1SD was 23.1±13.9 months; 43% were females. Data were collected on demographic and clinical characteristics. The stool work-up consisted of fresh smear and methylene blue and Kinyoun smears, as well as determination of pH and reducing substances. Stool culture was performed in samples with ³ 3 leukocytes/microscopic field and rotavirus antigen detection only in selected cases. Data were analyzed using descriptive statistics, chi², odds ratios, and 95% confidence intervals. Results. Enterophatogens (% identified were: rotavirus 47.1, Campylobacter jejuni 27.4, Salmonella spp. 5.1, Shigella spp. 4.3, Cryptosporidium parvum 2.8, Giardia lamblia 2.4, Blastocystis hominis 1.4, Entamoeba histolytica 0.7. An OR of 5.7 was obtained for isolation of enteroinvasive bacteria in the presence of fecal leukocytes. Lactose intolerance was detected in 19.1%. The frequencies of rotavirus antigen identification and lactose intolerance were significantly higher in infants; the OR for lactose intolerance in infants with rotavirus was 21. Mucus and blood in the stools were associated to enteroinvasive bacteria and Cryptosporidium parvum. Conclusions. The current stool work-up protocol allowed the identification of enteropathogenic parasites, rotavirus and lactose intolerance in a short period of time. Leukocytes in stools were associated to the isolation of enteroinvasive bacteria. The frequency of agents associated to diarrheal disease was similar to that from other national studies. This stool work-up protocol could be useful as a tool to limit the unnecessary prescription of drugs and to follow universal recommendations for dietary management of these patients.

    Infectious disease is a common cause of acute abdomen. The diagnosis is based on clinical examination and basic laboratory tests. However, medical imaging routinely performed according to the clinical findings is frequently useful. Hepatic and splenic abscesses are correctly demonstrated by ultrasonography and computed tomography. Ultrasonography is the reference standard for the diagnosis of acute cholecystitis. The US examination is also performed for the diagnosis of appendicitis and its complications. Ultrasonography and barium enema are commonly performed for the evaluation of sigmoid diverticulitis. Computed tomography is the reference standard to determine medical or surgical procedures. (authors). 20 refs., 15 figs.

    Daniel R Feikin

    Full Text Available BACKGROUND: Zinc treatment shortens diarrhea episodes and can prevent future episodes. In rural Africa, most children with diarrhea are not brought to health facilities. In a village-randomized trial in rural Kenya, we assessed if zinc treatment might have a community-level preventive effect on diarrhea incidence if available at home versus only at health facilities. METHODS: We randomized 16 Kenyan villages (1,903 eligible children to receive a 10-day course of zinc and two oral rehydration solution (ORS sachets every two months at home and 17 villages (2,241 eligible children to receive ORS at home, but zinc at the health-facility only. Children's caretakers were educated in zinc/ORS use by village workers, both unblinded to intervention arm. We evaluated whether incidence of diarrhea and acute lower respiratory illness (ALRI reported at biweekly home visits and presenting to clinic were lower in zinc villages, using poisson regression adjusting for baseline disease rates, distance to clinic, and children's age. RESULTS: There were no differences between village groups in diarrhea incidence either reported at the home or presenting to clinic. In zinc villages (1,440 children analyzed, 61.2% of diarrheal episodes were treated with zinc, compared to 5.4% in comparison villages (1,584 children analyzed, p<0.0001. There were no differences in ORS use between zinc (59.6% and comparison villages (58.8%. Among children with fever or cough without diarrhea, zinc use was low (<0.5%. There was a lower incidence of reported ALRI in zinc villages (adjusted RR 0.68, 95% CI 0.46-0.99, but not presenting at clinic. CONCLUSIONS: In this study, home zinc use to treat diarrhea did not decrease disease rates in the community. However, with proper training, availability of zinc at home could lead to more episodes of pediatric diarrhea being treated with zinc in parts of rural Africa where healthcare utilization is low.

  20. Post-infectious irritable bowel syndrome

    Institute of Scientific and Technical Information of China (English)

    Marroon Thabane; John K Marshall

    2009-01-01

    Post-infectious irritable bowel syndrome (PI-IBS) is a common disorder wherein symptoms of IBS begin after an episode of acute gastroenteritis. Published studies have reported incidence of PI-IBS to range between 5% and 32%. The mechanisms underlying the development of PI-IBS are not fully understood, but are believed to include persistent sub-clinical inflammation, changes in intestinal permeability and alteration of gut flora. Individual studies have suggested that risk factors for PI-IBS include patients' demographics, psychological disorders and the severity of enteric illness. However, PI-IBS remains a diagnosis of exclusion with no specific disease markers and, to date, no definitive therapy exists. The prognosis of PIIBS appears favorable with spontaneous and gradual resolution of symptoms in most patients.

    Full Text Available

    Infectious complications have been known to be a major cause of morbidity and mortality in CLL patients who are predisposed to infections because of both the humoral immunodepression inherent to hematologic disease, which is related to stage and duration of CLL, and to further immunosuppression related to therapy. The majority of infections in CLL patients treated with alkilating agents is of bacterial origin. The immunodeficiency and natural infectious history of alkylator-resistant, corticosteroid-treated patients appears to have changed with the administration of purine analogs, which has been complicated by very severe and unusual infections and also more viral infections due to sustained reduction of CD4-positive T lymphocytes. The following introduction of monoclonal antibody therapies, in particular alemtuzumab, further increased the immunodepression, increasing also infections which appeared more often in patients with recurrent neutropenia due to chemotherapy cycles.

    Epidemiological data regarding fungal infections in lymphoproliferative disorders are scarce. Italian SEIFEM group in a retrospective multicentre study regarding CLL patients reported an incidence of mycoses 0.5%; however, chronic lymphoproliferative disorders emerged as second haematological underlying disease after acute leukemia in a French study on aspergillosis; in particular CLL with aspergillosis accounted for a third of these chronic lymphoproliferative diseases presenting mould infection.

    2004-04-01

    We live in an ever more connected global village linked through international travel, politics, economics, culture and human-human and human-animal interactions. The realization that the concept of globalization includes global exposure to disease-causing agents that were formerly confined to small, remote areas and that infectious disease outbreaks can have political, economic and social roots and effects is becoming more apparent. Novel infectious disease microbes continue to be discovered because they are new or newly recognized, have expanded their geographic range, have been shown to cause a new disease spectrum, have jumped the species barrier from animals to humans, have become resistant to antimicrobial agents, have increased in incidence or have become more virulent. These emerging infectious disease microbes may have the potential for use as agents of bioterrorism. Factors involved in the emergence of infectious diseases are complex and interrelated and involve all classifications of organisms transmitted in a variety of ways. In 2003, outbreaks of interest included severe acute respiratory syndrome, monkeypox and avian influenza. Information from the human genome project applied to microbial organisms and their hosts will provide new opportunities for detection, diagnosis, treatment, prevention, control and prognosis. New technology related not only to genetics but also to satellite and monitoring systems will play a role in weather, climate and the approach to environmental manipulations that influence factors contributing to infectious disease emergence and control.

    Full Text Available Abstract Background Lack of exclusive breastfeeding among infants 0-5 months of age and no breastfeeding among children 6-23 months of age are associated with increased diarrhea morbidity and mortality in developing countries. We estimate the protective effects conferred by varying levels of breastfeeding exposure against diarrhea incidence, diarrhea prevalence, diarrhea mortality, all-cause mortality, and hospitalization for diarrhea illness. Methods We systematically reviewed all literature published from 1980 to 2009 assessing levels of suboptimal breastfeeding as a risk factor for selected diarrhea morbidity and mortality outcomes. We conducted random effects meta-analyses to generate pooled relative risks by outcome and age category. Results We found a large body of evidence for the protective effects of breastfeeding against diarrhea incidence, prevalence, hospitalizations, diarrhea mortality, and all-cause mortality. The results of random effects meta-analyses of eighteen included studies indicated varying degrees of protection across levels of breastfeeding exposure with the greatest protection conferred by exclusive breastfeeding among infants 0-5 months of age and by any breastfeeding among infants and young children 6-23 months of age. Specifically, not breastfeeding resulted in an excess risk of diarrhea mortality in comparison to exclusive breastfeeding among infants 0-5 months of age (RR: 10.52 and to any breastfeeding among children aged 6-23 months (RR: 2.18. Conclusions Our findings support the current WHO recommendation for exclusive breastfeeding during the first 6 months of life as a key child survival intervention. Our findings also highlight the importance of breastfeeding to protect against diarrhea-specific morbidity and mortality throughout the first 2 years of life.

    Two cases of acute, fatal, hepatitis occurred in young, striped skunks (Mephitis mephitis) trapped in southern Ontario. Histologically, lesions in the liver were similar to infectious canine hepatitis. A virus was isolated which produced large intranuclear inclusions in dog kidney cell cultures. These inclusions were Feulgen-positive and fluoresced green with acridine orange stain. The skunk hepatitis isolate was identified as the virus of infectious canine hepatitis by virus neutralization tests. PMID:172663

    Evacuation of residents and diarrhea disease outbreak in evacuation zone have become serious problem that frequently happened during flood periods. Limited clean water supply and infrastructure in evacuation zone contribute to a critical spread of diarrhea. Transmission of diarrhea disease can be reduced by controlling clean water supply and treating diarrhea patients properly. These treatments require significant amount of budget, which may not be fulfilled in the fields. In his paper, transmission of diarrhea disease in evacuation zone using SIRS model is presented as control optimum problem with clean water supply and rate of treated patients as input controls. Existence and stability of equilibrium points and sensitivity analysis are investigated analytically for constant input controls. Optimum clean water supply and rate of treatment are found using optimum control technique. Optimal results for transmission of diarrhea and the corresponding controls during the period of observation are simulated numerically. The optimum result shows that transmission of diarrhea disease can be controlled with proper combination of water supply and rate of treatment within allowable budget.

    Full Text Available BACKGROUND: The epidemiology of functional diarrhea and its impacts on Chinese remain unclear, and there are no data on the comparative epidemiology of functional diarrhea and diarrhea-predominant irritable bowel syndrome (IBS-D. This study was to explore the epidemiology of functional diarrhea and its impacts, and to identify its distinction from IBS-D. METHODS AND FINDINGS: A cross-sectional survey was conducted in 16078 respondents, who were interviewed under a randomized stratified multi-stage sampling design in five cities of China. All respondents completed the modified Rome II questionnaire, and the 36-item Short Form health survey (SF-36 was used for assessing health-related quality of life in 20% of the sample. Overall, 248 respondents (1.54% had functional diarrhea and 277 (1.72% had IBS-D. Functional diarrhea was positively associated with increasing age and body mass index (trend test P<0.05. The three most common symptoms for at least 3 weeks in the past months were loose, mushy or watery stools (n = 203, 81.85%, more than three bowel movements a day (n = 100, 40.32% and having to rush to the toilet to have a bowel movement (n = 72, 29.03%. Meaningful impairment was observed in 5 of the 8 SF-36 domains in respondents with functional diarrhea. The demographics are mostly similar between the respondents with functional diarrhea and IBS-D; however, respondents with IBS-D had more frequent symptoms of diarrhea and even lower scores in SF-36 domains than those with functional diarrhea. CONCLUSIONS: The prevalence of functional diarrhea in China is substantially lower than that in Western countries and relatively higher than that in other Asian countries. It impaired health-related quality of life, and respondents with IBS-D have even worse quality of life. Further population-based studies are needed to investigate the epidemiology of functional diarrhea and the differences between functional diarrhea and IBS-D.

According to the World Health Organization, a suspected case of SARS is defined as documented fever (temperature >38°C, lower respiratory tract symptoms, and contact with a person believed to have had SARS or history of travel to an area of documented transmission. A probable case is a suspected case with chest radiographic findings of pneumonia, acute respiratory distress syndrome (ARDS, or an unexplained respiratory illness resulting in death, with autopsy findings of ARDS without identifiable cause. In this article some SARS epidemiological data in Indonesia will also presented. There are 7 SARS suspected cases and 2 probable cases were registered in Indonesia on the period of 1 March to 9 July 2003, and no more cases were reported after that time. How will be SARS progression in the future will be a subject of discussion among scientist, and we will have to wait and be prepared for any development might occur.

    Pakistan is ranked 9th in terms of flood-affected countries worldwide. In the summer of 2010, the northern province of Khyber-Pakhtunkhwa received more than 312 mm of rain in a 56 hour period. This resulted in over 1 600 deaths across the region. In addition, over 14 million people were directly affected by this record-breaking deluge. Flood affected regions serve as ideal breeding grounds for pathogens, leading to the spread of diseases. The poor standards of hygiene in camps set up for individuals displaced by the floods also contribute to this. It is essential that those involved in relief efforts are aware of the epidemiology of diseases that have historically seen a sudden upsurge after natural disasters. Keeping this in mind, we conducted a simple review of literature. An extensive literature search was conducted using the PubMed data base and online search engines. Articles published in the last 20 years were considered along with some historical articles where a background was required. Seven major diseases were identified to increase substantially in the aftermath of natural disasters. They were then classified into acute and sub-acute settings. Diarrhea, skin & eye infections and leptospirosis were identified in the acute setting while malaria, leishmaniasis, respiratory infections and hepatitis were identified in the sub-acute setting.

    Emerging infectious diseases (EID) are defined as diseases that have appeared recently or that have recently increased in their frequency, geographical distribution or both. Commercial globalisation, population movements and environmental changes are the main factors favouring the international spread of microorganisms. Transport and communication development constitutes also a remarkable factor in the worldwide dispersion of microorganisms. The mass movement of large numbers of people creates new opportunities for the spread and establishment of common or novel infectious diseases. A surveillance system to detect emergent and re-emergent infections, a rapid responsiveness of healthcare systems and laboratories, vector control, and the provision of healthcare education programmes to inform the population of how to avoid infections are needed in order to stop the spread of infectious diseases.

    Full Text Available Infectious disease, especially virulent infectious disease, is commonly regarded as a cause of fluctuation or decline in biological populations. However, it is not generally considered as a primary factor in causing the actual endangerment or extinction of species. We review here the known historical examples in which disease has, or has been assumed to have had, a major deleterious impact on animal species, including extinction, and highlight some recent cases in which disease is the chief suspect in causing the outright endangerment of particular species. We conclude that the role of disease in historical extinctions at the population or species level may have been underestimated. Recent methodological breakthroughs may lead to a better understanding of the past and present roles of infectious disease in influencing population fitness and other parameters.

    Full Text Available The thymus is a central lymphoid organ, in wich T cell precursors differentiale and generate most of the so-called T cell reprtoire. Along with a variety of acute infectious diseases, we and others determined important changes in both microenvironmental and lymphoid compartments of the organ. For example, one major and common feature observed in acute viral, bacterial and parasitic diseases, is a depletion of cortical thymocytes, mostly those bearing the CD4-CD8 double positive phenotype. This occurs simmultaneously to the relative enrichment in medullary CD4 or CD8 single positive cells, expressing high densities of the CD3 complex. Additionally we noticed a variety of changes in the thymic microenvironment (and particularly is epithelial component, comprising abnormal location of thymic epithelial cell subsets as well has a denser Ia-bearing cellular network. Moreover, the extracellular matrix network was altered with an intralobular increase of basement membrane proteins that positively correlated with the degree of thymocyte death. Lastly, anti-thymic cell antibodies were detected in both human and animal models of infectious diseases, and in some of them a phenomenon of molecular mimicry could be evidenced. Taken together, the data receiwed herein clearly show that the thymus should be regarded as a target in infectious diseases.

    Southeast Asia is a hotspot for emerging infectious diseases, including those with pandemic potential. Emerging infectious diseases have exacted heavy public health and economic tolls. Severe acute respiratory syndrome rapidly decimated the region's tourist industry. Influenza A H5N1 has had a profound effect on the poultry industry. The reasons why southeast Asia is at risk from emerging infectious diseases are complex. The region is home to dynamic systems in which biological, social, ecological, and technological processes interconnect in ways that enable microbes to exploit new ecological niches. These processes include population growth and movement, urbanisation, changes in food production, agriculture and land use, water and sanitation, and the effect of health systems through generation of drug resistance. Southeast Asia is home to about 600 million people residing in countries as diverse as Singapore, a city state with a gross domestic product (GDP) of US$37,500 per head, and Laos, until recently an overwhelmingly rural economy, with a GDP of US$890 per head. The regional challenges in control of emerging infectious diseases are formidable and range from influencing the factors that drive disease emergence, to making surveillance systems fit for purpose, and ensuring that regional governance mechanisms work effectively to improve control interventions.

    Full Text Available Abstract Background There is a high incidence of diarrhea in traveling populations. Norovirus (NV infection is a common cause of diarrhea and is associated with 7% of all diarrhea related deaths in the US. However, data on the overall prevalence of NV infection in traveling populations is limited. Furthermore, the prevalence of NV amongst travelers returning to Europe has not been reported. This study determined the prevalence of NV among international travelers returning to Germany from over 50 destinations in and outside Europe. Methods Stool samples of a total of 104 patients with a recent ( Results In our cohort, NV infection was detected in 15.7% of returning travelers with diarrhea. The closer to the date of return symptoms appeared, the higher the incidence of NV, ranging as high as 21.2% within the first four days after return. Conclusions In our cohort, NV infection was shown to be frequent among returning travelers especially in those with diarrhea, with over 1/5 of diarrhea patients tested positive for NV within the first four days after their return to Germany. Due to this prevalence, routine testing for NV infection and hygienic precautions may be warranted in this group. This is especially applicable to patients at an increased risk of spreading the disease, such as healthcare workers, teachers or food-handlers.

    The acute phase response as indicated by serum haptoglobin and total haemolytic complement activity (CH50) was measured in 72 cross-bred steer calves purchased at sales in Ontario. During the 28 day (d) trial, 18 steers were randomly assigned to each of the following groups: 1) control; 2) vaccinated (Infectious Bovine Rhinotracheitis, Parainfluenza-3, Bovine Viral Diarrhea, Bovine Respiratory Synctial Virus vaccine plus Pasteurella haemolytica vaccine); 3) supplemental chelated Cr (0.14 mg/kg); and 4) Cr plus vaccines. Haptoglobin concentrations were low at arrival, increased (P 0.05) by day 14. Supplemental Cr reduced (P 0.05) than in healthy calves. Complement activity was lowest on day 7 (P 0.10). Complement activity did not increase on day 14 (P > 0.05) with Cr supplementation as in other treatments. Morbid calves had lower (P < 0.05) CH50 activity than healthy calves on day 14. Following antibiotic treatment, the Cr-supplemented group had higher (P < 0.05) CH50 than during morbidity. In general, chromium supplementation reduced the acute phase response in newly arrived feeder calves. PMID:8548694

    of the OIE List, including foot and mouth disease and classical swine fever. However, several infectious diseases are known to remain among herds, which produce a major effect in production due to losses by abortion, decrease of fertility and what it is more important, some of them represent barriers for export and constitute a risk of zoonosis for the population. In this work, a monitoring system based on the analysis of bulk milk antibodies by means of ELISA test, was implemented to study the epidemiology and distribution of 4 of the main bovine diseases that currently affect the IX Region of Chile (brucellosis, bovine leukaemia, IBR and BVD. The system allowed the surveillance of 279 dairies, which represented 43% of the dairies registered in IX the Region, and included 19,635 milking cows (14%. With this system, a high prevalence for leukaemia (59%, IBR (76% and BVD (96% could be established, whereas it was confirmed that brucellosis is restricted to a few dairies (5%. The surveillance system coupled to the satellite geographic information analysis, allowed to establish the space distribution of these diseases in the different communes of the Region, demonstrating to be an excellent and low cost support tool for the monitoring of the diseases in the herd, which guarantees the possibility of establishing this platform in the Region and its feasibility to project it at national level.

    The aim of this study was to explore infectious diseases related to the 2007 Huai River flood in Anhui Province, China. The study was based on the notified incidences of infectious diseases between June 29 and July 25 from 2004 to 2011. Daily incidences of notified diseases in 2007 were compared with the corresponding daily incidences during the same period in the other years (from 2004 to 2011, except 2007) by Poisson regression analysis. Spatial autocorrelation analysis was used to test the distribution pattern of the diseases. Spatial regression models were then performed to examine the association between the incidence of each disease and flood, considering lag effects and other confounders. After controlling the other meteorological and socioeconomic factors, malaria (odds ratio [OR] = 3.67, 95% confidence interval [CI] = 1.77-7.61), diarrhea (OR = 2.16, 95% CI = 1.24-3.78), and hepatitis A virus (HAV) infection (OR = 6.11, 95% CI = 1.04-35.84) were significantly related to the 2007 Huai River flood both from the spatial and temporal analyses. Special attention should be given to develop public health preparation and interventions with a focus on malaria, diarrhea, and HAV infection, in the study region. PMID:26903612

    @@DEFINITIONAcute diarrhoea is defined as passage of loose or watery stools at least three times in a 24 h period. When loose stools contain blood, it is called bloody diarrhoea (dysentery). It is the consistency of the stools which is most important rather than the frequency. Breast-fed babies often pass “pasty” stools frequently which is not diarrhoea. The mother can often tell accurately whether child has diarrhoea or not. MAGNITUDE OF THE PROBLEMAcute diarrhoea is an important cause of mortality and morbidity particularly in young children in the developing countries. Of the 11.6 million deaths among children less than five years old in all developing countries (1995) due to infectious diseases, 19% deaths are attributed to diarrhoeah]. In 1993, an estimated 3.2 million children below five years of age died from diarrhoea alone; 80 % of these deaths occurred in the first two years of life[2].

    Porcine epidemic diarrhea (PED) is a serious infection in neonatal piglets. As the causative agent of PED, porcine epidemic diarrhea virus (PEDV) results in acute diarrhea and dehydration with high mortality rates in swine. Dendritic cells (DCs) are highly effective antigen-presenting cells to uptake and present viral antigens to T cells, which then initiate a distinct immune response. In this study, our results show that the expression of Mo-DCs surface markers such as SWC3a(+)CD1a(+), SWC3a(+)CD80/86(+) and SWC3a(+)SLA-II-DR(+) is increased after incubation with UV-PEDV for 24h. Mo-DCs incubated with UV-PEDV produce higher levels of IL-12 and INF-γ compared to mock-infected Mo-DCs. Interactions between Mo-DCs and UV-PEDV significantly stimulate T-cell proliferation in vitro. Consistent with these results, there is an enhancement in the ability of porcine intestinal DCs to activate T-cell proliferation in vivo. We conclude that UV-PEDV may be a useful and safe vaccine to trigger adaptive immunity. PMID:27234553

    In this paper the molecular aspects of the relationships between infectious agents and autoimmune diseases, the mechanisms of immune response to infectious agents, and the more recent hypotheses regarding the cause of autoimmune diseases are discussed. The antigens are processed and selected by their immunogenicity, and presented by HLA molecules to the T cell receptor. These events initiate the immune response with the activation and proliferation of T-lymphocytes. Although there are several hypotheses regarding the cause of autoimmune diseases and too many findings against and in favor of them, there is still no conclusive data. All these hypothesis and findings are discussed in the context of the more recent advances. PMID:1615352

    Bronchiolitis is a common early childhood illness and an important cause of morbidity, it is the number one cause of hospitalization among US infants. Bronchiolitis is also an active area of research, and recent studies have advanced our understanding of this illness. Although it has long been the conventional wisdom that the infectious etiology of bronchiolitis does not affect outcomes, a growing number of studies have linked specific pathogens of bronchiolitis (e.g., rhinovirus) to short- and long-term outcomes, such as future risk of developing asthma. The authors review the advent of molecular diagnostic techniques that have demonstrated diverse pathogens in bronchiolitis, and they review recent studies on the complex link between infectious pathogens of bronchiolitis and the development of childhood asthma.

    Sudden sensorineural hearing loss (SSNHL) is a debilitating condition with an incidence of nearly 20 per 100,000 in populations. Metronidazole-induced ototoxicity is an extremely rare etiology of SSNHL. In this report, we describe a young female with bilateral SSNHL due to oral use of metronidazole. A 23 years old female presented to the emergency department with acute bilateral hearing loss. We found out that her hearing loss had started 4 days after initiation of metronidazole which was administered for treatment of diarrhea. This case report shows that physicians should be aware of the uncommon side effects while prescribing metronidazole to patients in order to manage the possible adverse events on time.

    2016-01-01

    Experimental in vitro and in vivo studies support the hypothesis that heat-treated, lyophilized Lactobacillus acidophilus LB cells and concentrated, neutralized spent culture medium conserve the variety of pharmacological, antimicrobial activities of the live probiotic strain against several infectious agents involved in well-established acute and persistent watery diarrhoea and gastritis. Heat-treated cells and heat-stable secreted molecules trigger multiple strain-specific activities explaining the therapeutic efficacy of L. acidophilus LB. This review discusses the current body of knowledge on the antimicrobial mechanisms of action exerted by L. acidophilus LB demonstrated in in vitro and in vivo experimental studies, and the evidence for the therapeutic efficacy of this anti-infectious biotherapeutic agent proved in randomized clinical trials for the treatment of acute and persistent watery diarrhoea associated with several intestinal infectious diseases in humans.

    Perumal, B; Black, E H; Levin, F; Servat, J J

    2012-05-01

    Non-infectious vasculitides comprise a large number of diseases. Many of these diseases can cause inflammation within the orbit and a clinical presentation, which mimics numerous other processes. Orbital disease can often be the initial presentation of a systemic process and early diagnosis can help prevent long-term, potentially fatal consequences. The evaluation and treatment of non-infectious orbital vasculitides are often complicated and require a thorough understanding of the disease and underlying systemic associations. The long-term prognosis visually and systemically must be weighed against the risks and benefits of the treatment regimen. A large variety of corticosteroid formulations currently exist and are the mainstay of initial treatment. Traditional steroid-sparing immunosuppressive agents are also an important arsenal against these vasculitides. Recently, a new class of drugs called biologics, which target the various mediators of the inflammation cascade, may potentially provide more effective and less toxic treatment. This review aims to synthesize the current literature on non-infectious orbital vasculitides. PMID:22361845

    AIM: To investigate the efficacy of a high-potency probiotic preparation on prevention of radiation-induced diarrhea in cancer patients.METHODS: This was a double-blind, placebo-controlled trial. Four hundred and ninety patients who underwent adjuvant postoperative radiation therapy after surgery for sigmoid, rectal, or cervical cancer were assigned to either the high-potency probiotic preparation VSL#3 (one sachet t.i.d.,) or placebo starting from the first day of radiation therapy. Efficacy endpoints were incidence and severity of radiation-induced diarrhea, daily number of bowel movements, and the time from the start of the study to the use of loperamide as rescue medication.RESULTS: More placebo patients had radiation-induced diarrhea than VSL#3 patients (124 of 239 patients, 51.8%, and 77 of 243 patients, 31.6%; P < 0.001) and more patients given placebo suffered grade 3 or 4 diarrhea compared with VSL#3 recipients (55.4% and 1.4%, P < 0.001). Daily bowel movements were 14.7 ± 6 and 5.1 ± 3 among placebo and VSL#3 recipients (P < 0.05), and the mean time to the use of loperamide was 86 ± 6 h for placebo patients and 122 ± 8 h for VSL#3 patients (P < 0.001).CONCLUSION: Probiotic lactic acid-producing bacteria are an easy, safe, and feasible approach to protect cancer patients against the risk of radiation-induced diarrhea.

Objective: To spotlight the common presentation of CCD for early management and prevention of complications. Subjects and methods: This is a retrospective case series study of patients diagnosed as CCD who were followed up in the pediatric department of Al-Adan Hospital, Kuwait. Results: Twelve patients diagnosed with CCD were born to consanguineous parents; had antenatal history of intrauterine growth retardation (IUGR; polyhydramnios; and distended hypoechoic fetal bowel; and presented with abdominal distension, hypotonia and muscle wasting. 90% of patients had maternal hypertension and 75% of patients had absence of normal meconium at birth. Our patients showed a decrease in serum sodium, potassium, chloride and urine chloride. Conclusion: A high level of suspicion for an early diagnosis of CCD should be considered for any infant presenting with chronic diarrhea, especially in the presence of consanguineous marriage, and the characteristic features in antenatal ultrasound. Thus, allowing for early investigations and appropriate management. Keywords: congenital chloride diarrhea, children, chronic diarrhea, metabolic alkalosis, prenatal diagnosis

    The aim of this study is to report a case of Clostridium difficile-associated diarrhea in an ocelot (Leopardus pardalis) in the state of Mato Grosso do Sul, Brazil. The animal, a 24-month-old male, was referred to the Centro de Reabilitação de Animais Silvestres (CRAS) with a history of having been run over and tibia and fibula fractures. After a surgery to repair the fractures, the ocelot underwent antibiotic therapy with two doses of sodium cefovecin, during which he presented with diarrhea. A stool sample was positive for A/B toxins by a cytotoxicity assay, and a toxigenic strain of C. difficile was isolated. No other enteropathogens were detected. The association between the history, clinical signs and laboratory exams confirmed the diagnosis of C. difficile-associated diarrhea. The present report confirms C. difficile as a potential pathogen for wild felids and suggests that the C. difficile-associated diarrhea should be considered in diarrhea cases, especially when the clinical signs began after antimicrobial use.

    Full Text Available Context Irritable bowel syndrome (IBS is a functional bowel disease characterized by abdominal pain and altered intestinal habits. The pathophysiology of IBS remains unclear. Recent studies have demonstrated that some IBS patients, especially in diarrhea-predominant IBS (IBS-D, display persistent signs of minor mucosal inflammation and a modified intestinal microflora. The mesalazine has known intestinal anti-inflammatory properties. Saccharomyces boulardii is a probiotic used for a long time in treatment of diarrhea, including infectious diarrhea. Objective Evaluate the effects of mesalazine alone, combined therapy of mesalazine with liophylised Saccharomyces boulardii or alone on symptoms of IBS-D patients. Methods Based on Rome III criteria, 53 IBS-D patients (18 year or more were included. To exclude organic diseases all patients underwent colonoscopy, stool culture, serum anti-endomisium antibody, lactose tolerance test and ova and parasite exam. Patients were divided in three groups: mesalazine group (MG - 20 patients received mesalazine 800 mg t.i.d. for 30 days; mesalazine and Saccharomyces boulardii group (MSbG - 21 patients received mesalazine 800 mg t.i.d. and Saccharomyces boulardii 200 mg t.i.d. for 30 days and; Saccharomyces boulardii group (SbG – 12 patients received Sb 200 mg t.i.d. for 30 days. Drugs that might have any effect on intestinal motility or secretion were not allowed. Symptom evaluations at baseline and after treatment were performed by means of a 4-point likert scale including: stool frequency, stool form and consistency (Bristol scale, abdominal pain and distension. Paired t test and Kruskal-Wallis test were used for statistical analyses. Results Compared to baseline, there were statistically significant reduction of symptom score after 30 th day therapy in all three groups: MG (P<0.0001; MSbG (P<0.0001 and in SbG (P = 0.003. There were statistically significant differences in the symptom score at 30 th day

    Full Text Available We experienced a rare case of 72-year-old woman with acute onset collagenous colitis (CC induced by lansoprazole. The patient developed acute abdominal pain, watery diarrhea, and melena that are quite rare in usual CC. We could find the characteristic colonoscopic findings such as active long liner ulcers in the patient. We also observed the healing courses of these unique findings. Our case indicates two important points of view. (1 CC sometimes develops with acute onset symptoms which resemble those of ischemic colitis. (2 Colonoscopy would be useful and necessary to distinguish acute onset CC and ischemic colitis.

    Objective To summarize lessons learned from an outbreak of severe acute respiratory syndrome (SARS) in China during the spring of 2004. Methods Data of SARS cases were officially reported by Beijing Municipal Center for Disease Control and Prevention (BCDC) and Anhui Provincial Center for Disease Control and Prevention (APCDC) and results of epidemiological investigations were collected and analyzed. Results Three generations of 11 cases of SARS were identified during the outbreak. Initial two cases were most likely to be infected in Diarrhea Virus Laboratory of National Institute of Virology, China Centers for Disease Control and Prevention and main mode of transmission was direct contact with SARS patients. Delay in detecting initial case resulted in spread of the illness at hospitals and communities with two generations of secondary cases. Conclusions SARS outbreak in 2004 has yielded following lessons for public health globally. (1) Lab bio-safety programs should be made and should be strictly abided by. Studies in highly pathogenic viruses such as SARS coronavirus should be utmost cautious. (2) Management systems of occupational exposure to virus and disease surveillance need to be strengthened to take all risk factors into account so as to detect potential patients with infectious disease as early as possible.

    Diarrhea is the fourth leading cause of child mortality in Ghana. In 2010, Ghana endorsed guidelines from the World Health Organization and the United Nations Children's Fund for use of zinc with low-osmolarity oral rehydration salts (ORS) for the treatment of acute childhood diarrhea. From late 2011 through 2014, the Strengthening Health Outcomes through the Private Sector (SHOPS) project implemented a comprehensive program in 3 regions of Ghana to increase the availability and use of ORS and zinc and to decrease incorrect use of antibiotics and antidiarrheals. The program included (1) partnering with local pharmaceutical firms to introduce and market locally produced zinc products, (2) collaborating with the Ghanaian Pharmacy Council to provide training and supportive supervision of private-sector providers on diarrhea management, and (3) conducting mass media campaigns to raise caregiver awareness. We evaluated the effect of this program using a baseline survey of 754 caregivers of children under 5 with diarrhea at the start of the intervention in 2012 and a follow-up survey of 751 caregivers in 2014. Regression analysis showed that use of ORS with zinc increased from 0.8% in 2012 to 29.2% in 2014 (P<.001), and antibiotic use declined from 66.2% to 38.2% (P<.001) during the same period. The magnitude and statistical significance of these results remained the same after including potential confounding factors as covariates. Inappropriate antibiotic use, however, remained high at follow-up. We conclude that similar programs applied in other settings have the potential to rapidly scale up use of ORS and zinc. Additional efforts are required to reduce persistent incorrect antibiotic use. PMID:27353619

    A new, hypervirulent strain of Clostridium difficile, called NAP1/BI/027, has been implicated in C. difficile outbreaks associated with increased morbidity and mortality since the early 2000s. The epidemic strain is resistant to fluoroquinolones in vitro, which was infrequent prior to 2001. The name of this strain reflects its characteristics, demonstrated by different typing methods: pulsed-field gel electrophoresis (NAP1), restriction endonuclease analysis (BI) and polymerase chain reaction (027). In 2004 and 2005, the US Centers for Disease Control and Prevention (CDC) emphasized that the risk of C. difficile-associated diarrhea (CDAD) is increased, not only by the usual factors, including antibiotic exposure, but also gastrointestinal surgery/manipulation, prolonged length of stay in a healthcare setting, serious underlying illness, immune-compromising conditions, and aging. Patients on proton pump inhibitors (PPIs) have an elevated risk, as do peripartum women and heart transplant recipients. Before 2002, toxic megacolon in C. difficile-associated colitis (CDAC), was rare, but its incidence has increased dramatically. Up to twothirds of hospitalized patients may be infected with C. difficile. Asymptomatic carriers admitted to healthcare facilities can transmit the organism to other susceptible patients, thereby becoming vectors. Fulminant colitis is reported more frequently during outbreaks of C. difficile infection in patients with inflammatory bowel disease (IBD). C. difficile infection with IBD carries a higher mortality than without underlying IBD. This article reviews the latest information on C. difficile infection, including presentation, vulnerable hosts and choice of antibiotics, alternative therapies, and probiotics and immunotherapy. We review contact precautions for patients with known or suspected C. difficileassociated disease. Healthcare institutions require accurate and rapid diagnosis for early detection of possible outbreaks, to initiate

  8. Diagnosis and Management of AIDS-related Diarrhea

    Full Text Available The spectrum of illness associated with the acquired immunodeficiency syndrome (AIDS has been increasing since the initial description in 1981. While virtually all organ systems may be affected, the gastrointestinal tract appears to be a major target. Diarrhea is the most common symptom, affecting up to half of all AIDS patients during the course of their disease. Although diarrhea occurs frequently, its optimal management remains controversial. An extensive evaluation including stool studies and endoscopic biopsies of both the colon and small intestine has been widely recommended to identify all potential pathogenic organisms. An alternative approach is a more limited evaluation consisting of stool and blood cultures followed by symptomatic treatment with antidiarrheal agents if no specific organisms are identified. The clinical presentation of the most common opportunistic pathogens are reviewed, including several recently discovered organisms. Recommendations for treatment are followed by a brief discussion of management strategies used to care for patients with AIDS-related diarrhea.

    The aim of this study was to investigate the frequency of intestinal parasites in patients with chronic diarrhea and clarify the importance of these parasitic pathogens in such cases. A total of 60 pediatric patients with chronic diarrhea between June 2012 and October 2014 were enrolled in the study. Out of 60 stool samples, five were positive for Giardia lamblia, two, Dientamoeba fragilis, and one, Blastocystis hominis. One stool sample was positive for Entamoeba hartmanni and B. hominis, another one was positive for G. lamblia and B. hominis, another, G. lamblia and E. hartmanni and one sample was positive for Enterobius vermicularis, D. fragilis and B. hominis together. Parasitic infection, which decreases quality of life and increases susceptibility to other infections, should not be neglected, particularly in patients with chronic diarrhea. Accurate diagnosis decreases morbidity and mortality in patients with parasite infection. PMID:27322863

    Although diarrhea is the predominant bowel dysfunction in as many as one-third of patients with irritable bowel syndrome (IBS), it is unclear whether there is a specific disorder of intestinal fluid or electrolyte secretion in IBS. Diarrhea is generally considered a result of accelerated colonic transit in patients with IBS. Although a primary secretory diathesis has not been well-documented in patients with IBS with diarrhea (IBS-D), several mechanisms that could potentially contribute to intestinal secretion have been reported. Some of these mechanisms also influence motor and secretory dysfunctions that contribute to the pathophysiology of IBS-D. We review the evidence supporting secretion in IBS-D caused by peptides and amines produced by enteroendocrine cells or submucosal neurons, enterocyte secretory processes, and intraluminal factors (bile acids and short-chain fatty acids). Understanding these mechanisms and developing clinical methods for their identification could improve management of patients with IBS-D. PMID:25041862

    Full Text Available The acute schistosomiasis is the toxemic disease that follow the Schistosoma cercariae active penetration trough screen in the immunologicaly naive vertebrate host. The clinical picture starts two to eight weeks after the first contact with the contaminated water. Susceptible patients present a syndrome comprising fever, diarrhea, toxemia and hepatosplenomegaly. Diagnosis is based on epidemiological and clinical features, presence of Schistosoma eggs in the feces, enlargement of abdominal lymph nodes by ultrasonography and by detection of high antibodies levels against the antigen keyhole limpet haemocyanin. Different rates of cure have been observed with specific medication and for the most severe clinical presentations the use of steroids reduces the systemic and allergic manifestations.

    Full Text Available Standard recommended guidelines for diagnosis of infectious keratitis do exist. Based on an extensive Medline literature search, the various investigative modalities available for aiding the diagnosis of microbial keratitis have been reviewed and described briefly. Preferred practice patterns have been outlined and the importance of routine pre-treatment cultures in the primary management of infectious keratitis has been highlighted. Corneal scraping, tear samples and corneal biopsy are few of the specimens needed to carry out the investigative procedures for diagnosis and for initiating therapy in cases of microbial keratitis. In bacterial, fungal and amoebic keratitis, microscopic examination of smears is essential for rapid diagnosis. Potassium hydroxide (KOH wet mount, Gram′s stain and Giemsa stain are widely used and are important for clinicians to start empirical therapy before microbial culture results are available. The usefulness of performing corneal cultures in all cases of suspected infectious keratitis has been well established. In cases of suspected viral keratitis, therapy can be initiated on clinical judgment alone. If a viral culture is needed, scrapings should directly be inoculated into the viral transport media. In vivo confocal microscopy is a useful adjunct to slit lamp bio-microscopy for supplementing diagnosis in most cases and establishing early diagnosis in many cases of non-responding fungal and amoebic keratitis. This is a non-invasive, high resolution technique which allows rapid detection of Acanthamoeba cysts and trophozoites and fungal hyphae in the cornea long before laboratory cultures give conclusive results. Other new modalities for detection of microbial keratitis include molecular diagnostic techniques like polymerase chain reaction, and genetic finger printing by pulsed field gel electrophoresis.

    Full Text Available Celiac disease presents with a wide spectrum of symptoms and signs. Some patients may be asymptomatic though some may present with acute celiac crisis, which is a rare and serious complication of celiac disease. Here we present a patient who presented with a physically ill appearance, hypokalemia, hypoalbuminemia and was treated successfully with gluten-free diet, steroids and electrolyte replacement therapy. Acute celiac crisis, which is a rare complication of celiac disease with increased mortality, should be considered in differential diagnosis of patients with chronic diarrhea, hypernatremia, hypokalemia, hypoalbuminemia and metabolic acidosis and appropriate treatment should be started as soon as possible.

    The exact number of patients with chronic kidney disease (CKD) in Asia Pacific is uncertain. In numeric terms, the region is home to the largest population of patients with untreated chronic kidney failure. The climatic, geographic, social, cultural, economic, and environmental diversity within this region is higher than in any other part of the world. Large parts of the region face a climate-related burden of infectious diseases. Infections contribute to the development and progression of CKD and complicate the course of patients with pre-existing CKD (especially those on dialysis therapy or who are immunosuppressed), increase the cost of CKD care, and contribute to mortality and morbidity. Kidney involvement is a feature of several infectious diseases prevalent in Asia Pacific. Examples include malaria, leptospirosis, scrub typhus, tuberculosis, hepatitis B and C virus, dengue hemorrhagic fever, and Hantaan virus infections. The contribution of infection-associated acute kidney injury to the overall burden of CKD has not been evaluated systematically. Research is needed to quantify the impact of infections on kidney health by undertaking prospective studies. Nephrologists need to work with infectious disease research groups and government infection surveillance and control programs. PMID:26943982

    Infectious disease remains current worldwide. During the second half of 2014 an outbreak of ebolavirus hit West Africa with implications in the rest of the world. In fact, Spain declared the first imported case of this infection. Multiresistant enterobacteria outbreaks are emerging all around the world in a moment on which WHO draws attention to the limited resources, coining the term "post antibiotic era". On the other hand, 2014 went down in history as one in which hepatitis C is cured.

    Full Text Available Infectious bronchitis is an acute viral disease with high contagious and mortality among chicks. The aim of this study was to survey of relation between ascites syndrome incidence and infectious bronchitis in broiler chickens by ELISA method in Iran. Eight Ross strain broiler farm affected by infectious bronchitis were selected in this study. Blood samples were gathered early stages of disease and blood sampling was repeated two times with seven days interval. ELISA serologic test was used for approving the determination of infectious bronchitis. In addition, in order to differential diagnosis of Newcastle and influenza (H9N2 some relevant experiments were conducted. The rate of mortality in any farm during rearing, autopsy and the cause of mortality were recorded. Ascites cases were calculated in terms of prevalence. The growth parameters, FCR, final weight, total consumption of grain at each farm were calculated and mentioned. Based on obtained results in this study, the mean rate of mortality caused by ascites syndrome has been increased meaningfully in herds affected by infectious bronchitis compared with control group. In eight understudied farms affected by infectious bronchitis, the mean rate of Ascites mortality was 3% such that the mean rate of Ascites mortality was 0.5% at previous periods. Based on relevant results also final weight mean in affected herds with infectious bronchitis was lower compared with previous periods. Meanwhile, FCR in affected herds with infectious bronchitis was high compared with healthy herds. In this research demonstrated that there is positive correlation between infectious bronchitis and Ascites syndrome and the correlation is significant (p<0.05.

    Full Text Available The basic disorder in acute gastroenteritis is the disrupted transport of water and electrolytes, to a different degree. The objective of these investigations was to evaluate the efficacy of two oral rehydration solutions (ORS in the treatment of acute gastroenteritis in suckling piglets. Fifty piglets, 20 with acute gastroenteritis and 30 healthy controls aged 10 days were chosen at random upon the incidence of diarrhea, for one of two ORS treatments (ORS-1 and ORS-2. The piglets with diarrhea were administered a probiotic per os on the first day and an antibiotic parenterally, until the diarrhea disappeared. All the piglets were followed clinically from days 1-6 of the investigations. Faeces samples were taken for bacteriological culture on the first day. Clinical signs of hydration were better, as well as the difference in body mass of piglets with diarrhea under the ORS-2 treatment which was significantly higher (p=0.036 in comparison with the difference in piglets under the ORS-1 treatment. All piglets with diarrhea had normally formed faeces on the sixth day. Escherichia coli was isolated from faeces of 48 piglets. Piglets with acute gastroenteritis, treated with ORS with a higher osmolarity and which contained instead of citrate, bicarbonates in higher concentrations, with less potassium, more sodium and more chlorine had a better state of hydration, with a significantly bigger difference in body mass, and the results of their control group were not significantly different against those of piglets treated with ORS of a different composition.

    Acute interstitial pneumonia (AIP) of feedlot cattle is a sporadically occurring respiratory condition that is often fatal. Affected cattle have a sudden onset of labored breathing. There is no confirmed effective treatment of feedlot AIP; however, administration of antibiotics effective against common bacterial respiratory pathogens and nonsteroidal anti-inflammatory drugs, especially aspirin, has been recommended. Protective strategies are not well defined, but efforts to limit dust exposure and heat stress; to ensure consistent formulation, mixing, and delivery of feed; and to identify and treat infectious respiratory disease in a timely manner may decrease rates of feedlot AIP.
