Abstract
INTRODUCTION Acute gastroenteritis is one of the most common causes of hospital admission in children. Treatment regimens differ depending on the pathogen. In our study, we aimed to evaluate the epidemiological and clinical features of pediatric patients whose gastrointestinal agents were detected by multiplex PCR. MATERIALS AND METHODS The study included 131 pediatric patients who were followed up at Eskişehir Osmangazi University, Pediatric Department between January 2018 and December 2021.Gastrointestinal pathogens were detected in stool samples by multiplex PCR. The epidemiological and clinical features were reviewed retrospectively. RESULTS A total of 203 gastrointestinal pathogens were detected from the stool samples of 131 cases. Of these cases, 56% were male and 44% were female. The mean age was 66 (2-204) months. The most common symptoms were diarrhea, fever, vomiting and abdominal pain. The pathogen detection rate was 69% by multiplex PCR. A single pathogen was detected in 85 (65%) cases and multiple pathogens were detected in 46 (35%) cases. The most common pathogens were enteropathogenic Escherichia coli (EPEC, 23%), Clostridium difficile (21%), norovirus (17%), rotavirus (15%), salmonella (12%) and enterotoxigenic E. coli (ETEC, 11%). Stool culture was positive in 16 (12%) cases and microscopic examination positive in 17 (13%) cases. Probiotic treatment was given to 119 (92%) cases and antimicrobial treatment (metroinidazole, ceftriaxone, azithromycin and oral vancomycin) to 34 (26%) cases. Of the cases, 56 (42%) had chronic disease, 40 (30%) had a history of previous antibiotic use and 17 (13%) had a history of hospitalization in the intensive care unit. CONCLUSION The sensitivity of the multiplex PCR in the detection of acute gastroenteritis agents is higher than stool microscopy, stool culture and stool antigen tests. However, due to the inability to distinguish between colonization, carrier state and pathogenicity, it should be evaluated together with other diagnostic tests and clinical findings in order to determine whether the determined agent is pathogenic or not and in the regulation of antimicrobial therapy.

Abstract
Objective Gastroenteritis is a disease that affects all age groups, especially children, and causes high mortality and morbidity in all countries. The most common agents of acute gastroenteritis are viral agents. As a result, millions of diarrhea attacks and hospital admissions occur worldwide every year due to viral gastroenteritis. This study uses the multiplex polymerase chain reaction (PCR) method to investigate the viruses that are the causative agents of viral gastroenteritis in the pediatric patient group in Konya, Turkey.
Methods Stool samples of 94 patients aged 0 to 18 years sent from Emergency clinics and Pediatric outpatient clinics, Meram Medical Faculty Hospital Pediatric clinics, Konya Necmettin Erbakan University to Medical Microbiology Laboratory with a diagnosis of gastroenteritis between February and December 2018 were included in the study. Stool samples were stored at –80°C until the time of the analysis. Deoxyribonucleic acid/ribonucleic acid isolation from stool samples was performed with EZ1 Virus Mini Kit v2.0 (Qiagen, Hilden, Germany) using an automatic extraction system (BioRobot EZ1 system, Qiagen). The presence of astrovirus, rotavirus, adenovirus, norovirus (GI, GII), and sapovirus agents was investigated by the multiplex PCR method (Fast Track Diagnostics, Luxembourg) viral gastroenteritis kit.
Results Viral gastroenteritis agents were detected in 56.3% of the patients. One viral agent was detected in 47 (50%) of these patients and at least two viral agents in 6 (6.3%) of them. Norovirus GII was detected in 20 (21.2%) of the children included in the study, adenovirus in 13 (13.8%), rotavirus in 11 (12.8%), astrovirus in 11 (11.7%), sapovirus in 4 (4.2%), and norovirus GI in 1 (1.06%). When the distribution of viral agents was examined by months, the most number of agents were observed (21; 35%) in May, followed by April and June (12; 20%). Considering the distribution of the prevalence of the agents by age, it was seen to be mainly between 0 and 12 months (42%).
Conclusion Considering that the most common viral agent in our region is norovirus GII, it will be useful to investigate the norovirus that is not routinely examined in children who are admitted to clinics with the complaint of gastroenteritis. It will be appropriate to examine routinely adenovirus, rotavirus, and norovirus in the laboratory, especially in children with diarrhea and vomiting in the winter and spring months.

Abstract
BACKGROUND Acute gastroenteritis (AGE) remains a significant cause of diarrhea that affects children worldwide. It is usually caused by viral agents, including rotavirus (RV), norovirus (NoV), adenovirus (AdV), astrovirus (AstV), and sapovirus (SaV), and the disease severity varies accordingly. Here, we report the association of clinical severity among AGE-infected pediatrics caused by a single viral pathogen, coinfection (viral-viral), mixed infection (viral-bacterial), and AGE-negative samples. METHODS A total of 901 pediatric patients were admitted with AGE to the Pediatric Emergency Center of Hamad Medical Corporation in Qatar from June 2016 to June 2018. The age of the subjects ranged between 3 months and 14 years (median of 16 months). Virus antigens detection was performed by using Film Array Gastrointestinal (GI) Panel kit. AGE severity was assessed using the Vesikari Clinical Severity Scoring System. Multivariable multinomial logistic regression was used to model the five AGE viral agents' likelihood in relation to severity versus co-infection, mixed infection, and AGE-negative samples. RESULTS AGE was most common in pediatrics aged 1-3 years (median age = 1.25 years) and more frequent in males than females, with a ratio of 1:0.8. About 19.2% of the infections were caused by NoV, followed by RV (18.2%), AdV (6.5%), SaV (2.3%), and AstV (1.8%). The majority of viral agents were detected higher in mixed infection (32.1%) than coinfection (4.9%). Based on the Vesikari score system, severe clinical illness was recorded among pediatrics infected with RV (82.2%) and NoV (75.7%). Further on multivariable analysis, compared to testing negative, the odds of detecting RV was three times significantly higher in children with severe symptoms relative to those with moderate (adjusted-odds ratio [a-OR] = 3.10; 95% confidence interval [CI] = 1.82-5.28). Similar results were observed when considering RV relative to co-infection and mixed infection (a-OR = 2.59; 95% CI = 1.23-5.48 and a-OR = 2.06; 1.28-3.30, respectively). About one-third of the study sample were Qatari children with AGE (33%), whereas 35% and 32% were pediatrics from the Middle East and North Africa region, excluding Qatari and nonregions. CONCLUSION This study underlines the association of disease severity among AGE-infected pediatrics in Qatar. The overall Vesikari median score was significantly high, followed by more frequent hospitalization among RV-infected pediatrics compared to others. There was no reduction in the disease severity among RV-infected regardless of the vaccine dose.

Abstract
Acute gastroenteritis (AGE) remains a major cause of diarrhea in developing and developed countries. Rotavirus (RV) is a leading cause of severe pediatric diarrhea worldwide. Here we report on the prevalence of circulating genotypes in association with demographics and clinical manifestations outcomes in Qatar. A total of 231 RV-positive fecal samples were collected from children suffering from AGE during 3 years study period between June 2016 and June 2019. The age of the subjects ranged between 2 months and 14 years (median of 16 months). The VP4 and VP7 were amplified and sequenced. Phylogenetic analyses were performed using MEGA7.0. Pearson's chi-squared test was used to determine significant differences for comparisons of general categorical variables. RV infections were most common in children between 1 and 3 years of age (49%), followed by those < 1 year and > 3 years of age (33% and 28%, respectively). RV infections were more frequent in males than females, with a ratio of 1.4:1. RV infections occurred throughout the year, with a noticeable increase in summer (42.8%) and a drop in winter (20.1%). RV genotypes G3P[8] (30.8%), G2P[8] (12.3%), G4P[8] (11.7%), and G1P[8] (10.4%) were the common genotypes during the study period. The G3P[8] strain detected in our study revealed similarities to the equine-like G3P[8] (10.3%; 24/231) (KT988229.1), Wa-like genomic constellation (9%; 21/231) (MF563894.1), and DS-1-like strains (6.4%; 15/231) (LC386081.1). Based on the Vesikari score system, severe clinical illness including diarrhea and vomiting (average frequency: 4 to 5 times/day) was recorded for G3P[8] group, followed by G9P[8], G4P[8], and G1P[8]. Higher incidence for G3P[8], G2P[8], G4P[8], and G1P[8] were reported in Qatari subjects compared to other nationalities. The multinational status of a small country explains the wide diversity of circulating RV genotypes in Qatar. The highest prevalence and severe illnesses were recorded to G3P[8], which is different from other surrounding countries/global levels.

Abstract
We aimed to describe rotavirus epidemiology and clinical findings including extraintestinal manifestations in a setting that has yet to introduce rotavirus vaccines in the national immunization program. A literature search was performed by using the key words "Turkey" and "rotavirus." Ninety-eight studies published between 1987 and 2016 including epidemiological, clinical, and genotypical data at least 1 year duration were included. There were a total of 117 741 children with diarrhea and 26 566 rotavirus gastroenteritis with a median detection rate 31.8% (95% CI, 31.3-32.4) under 5 years of age. The rate of dehydration was 47% (95% CI, 23.4-91.6). There were 328 cases reported to be presenting with a various complication related to rotavirus in 2750 children in eight studies. The overall complication rate was 11.7% (95% CI, 10.7-12.9). The cumulative incidence of the most common genotypical combinations circulating worldwide was only 59.7% (G9[P8], 25%; G1[P8], 22%; G2[P4], 5.6%; G3[P8], 2.6%; G4[P8], 4.5%) whereas mixed, untypeable, and other genotypes were 2.4%, 15%, and 22.9% respectively. Our results point out the importance of rotavirus vaccination by presenting that rotavirus may cause severe complications besides severe gastroenteritis. The role of strain diversity in the variability of clinical presentations of rotavirus infections needs to be further investigated.

Abstract
Background Rotavirus is the leading cause of acute gastroenteritis in children and is associated with neurological complications such as seizures and encephalopathy. The aim of this study was to investigate the presentation and complications of rotavirus compared to non-rotavirus gastroenteritis in UK children. Methods This was a retrospective, case-control, hospital-based study conducted at three sites in east London, UK. Cases were children aged 1 month to 16 years diagnosed with acute gastroenteritis between 1 June 2011 and 31 December 2013, in whom stool virology investigations confirmed presence of rotavirus by PCR. They were matched by age, gender and month of presentation to controls with rotavirus-negative gastroenteritis. Results Data were collected from 116 children (50 cases and 66 controls). Children with rotavirus gastroenteritis tended to present more frequently with metabolic acidosis (pH 7.30 vs 7.37, P = 0.011) and fever (74% versus 46%; P = 0.005) and were more likely to require hospitalisation compared to children with non-rotavirus gastroenteritis (93% versus 73%; P = 0.019). Neurological complications were the most common extra-intestinal manifestations, but did not differ significantly between children with rotavirus-positive gastroenteritis (RPG) and rotavirus-negative gastroenteritis (RNG) (24% versus 15%, respectively; P = 0.24). Encephalopathy occurred only in children with rotavirus infection (n = 3, 6%). Conclusion Rotavirus causes longer and more severe disease compared to other viral pathogens. Seizures and milder neurological signs were surprisingly common and associated with multiple pathogens, but encephalopathy occurred only in children with rotavirus gastroenteritis. Rotavirus vaccination may reduce seizures and presentation to hospital, but vaccines against other pathogens causing gastroenteritis are required.

Abstract
Rotavirus (RV) is the leading cause of severe acute gastroenteritis (AGE) worldwide. Consequently, we conducted a systematic literature review on articles studying RV in the 25 countries of the MENA region during the past 15years (2000-2015). The methods and reporting were set according to the 2015 preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) and based on the elements from the international prospective register of systematic reviews (PROSPERO). Our literature search identified 169 studies meeting our predefined inclusion criteria. Studies reporting on RV were conducted in 19 out of the 24 countries of the MENA region. The largest number of studies was reported in Turkey (n=32), Iran (n=31), Saudi Arabia (n=19) and Egypt (n=17). The majority of studies reporting on RV gastroenteritis rates were clinical observational studies. In 115 studies out of 169, RV was reported among in-patients whereas 35 studies reported RV among outpatients. The predominantly reported RV genotype in the region was G1[P8] followed by G2[P4] and G9[P8]. The majority of studies (n=108) were conducted among children less than 5years of age whereas the remaining studies reported on AGE among other age groups and rarely adults. In MENA countries, RV infection was reported all year round with peaks described in cold as well as hot months. This systematic review provides a current update on the epidemiology of RV-associated gastroenteritis in countries of the MENA region and draws attention to the major gaps existing in the continuous monitoring of RV.

Abstract
BACKGROUND For children under 5 years of age, 1700 000 000 episodes of diarrhea are seen worldwide, and death occurs in 700 000 of these cases due to diarrhea. Rotavirus is an important cause of diarrhea in this age group, and many studies have shown that vitamin D plays a pivotal role in the immune system, as well as in antimicrobial peptide gene expression. In addition, lower vitamin D has been correlated with higher rates of infectious diseases such as respiratory tract infection, tuberculosis, and viral infection. METHODS Seventy patients with rotaviral diarrhea and 67 healthy patients were enrolled in this study. Serum 25-hydroxy vitamin D(3) (25(OH)D(3)), parathormone, calcium, phosphate, alkaline phosphatase, complete blood count parameters, and C-reactive protein were compared between pre-school children hospitalized due to rotaviral diarrhea and healthy children. Additionally, birthweight, feeding habits in the first 6 months of life, vitamin D and multivitamin supplements, and rotaviral vaccinations were also evaluated in each group. RESULTS There were no differences between the groups with regard to gender and age, but 25(OH)D(3) was significantly different: 14.6 ± 8.7 ng/mL in the rotaviral diarrhea patients versus 29.06 ± 6.51 ng/mL in the health controls (P < 0.001), and serum 25(OH)D(3) <20 ng/mL (OR, 6.3; 95%CI: 3.638-10.909; P < 0.001) was associated with rotaviral diarrhea. CONCLUSIONS Low vitamin D is associated with rotaviral diarrhea. This is the first study in the literature to show this, and this result needs to be repeated in larger controlled clinical studies.

Abstract
BACKGROUND Diarrhea is a leading cause of child mortality worldwide. Rotavirus is one of the most common causes of severe diarrhea and dehydration in children. Authors reviewed epidemiological and clinical data of the rotavirus diarrhea in Kosovo. METHODS This is a prospective study carried between January 1st and December 31st 2011. All data, comprising demographics, nutrition, clinical presentation, laboratory findings, management and outcome of the rotavirus diarrhea are collected on the specially designed form. RESULTS 116 children with rotavirus diarrhea are included in the study. The majority boys (74.4%) and children aged 0 - 12 months (82.75%). Mean age of children in the study was 16.38 months. Almost every third child in the study was hypotrophic (29.2%). More than half of the infants (55.2%) were on mixed food, somewhat more than every third was breast feeding (36.45%), and every twelfth (8.33%) was on artificial milk (animal or formula). Apart from diarrhea, present in all patients, vomiting (97.41%) and fever (43.96%) were characteristics of the clinical presentation of the diarrhea. Two thirds of the children had mild grade dehydration (70.7%). All patients recovered with no sequels. CONCLUSION Rotavirus continues to be responsible for a significant portion of acute diarrhea in Kosovo. Clinical features, epidemiological data and the agglutination test are safe enough to establish the diagnosis. Treated correctly rotavirus diarrhea has a favorable outcome.

Abstract
Diarrheal diseases are a great public health problem; they are among the most causes leading to morbidity and mortality of infants and children particularly in developing countries and even in developed countries. Rotavirus is the most common cause of severe gastroenteritis in infants and young children in both developed and developing countries. The purpose of this study was to determine the incidence rate of Rotavirus infection, its genotypes, and risk factors among children with diarrhea in Taiz, Yemen. 795 fecal samples were collected from children (less than 5 years old), suffering from diarrhea and attending the Yemeni-Swedish Hospital (YSH) in Taiz , Yemen, from November 2006 to February 2008. Rotavirus was detected by enzyme linkage immunosorbent assay (ELISA) on stool specimens of children. Genotypes of Rotavirus were characterized by reverse transcriptase-polymerase chain reaction (RT-PCR) and polyacrylamide gel electrophoresis (PAGE). The results showed that 358 (45.2%) were Rotavirus-positive and the most prevalent genotypes were G2P[4] (55%), followed by G1P[8] (15%). In addition, Rotavirus was found through the whole year; however, higher frequency during the summer season (53.4%) and lower frequency during the winter season (37.1%).

Abstract
Purpose Rotavirus (RV) is the leading cause of morbidity and mortality in children under 5 years of age worldwide. This study assessed the role of RV as a cause of gastroenteritis (GE)-associated hospitalization in children, generating baseline information to evaluate the potential impact of the RV vaccine in reducing RVGE disease burden in the Kingdom of Bahrain. Methods This single, pediatric hospital-based surveillance study was conducted over a period of 12 months beginning April 1, 2006. A total of 314 children aged under 5 years and hospitalized due to GE were enrolled in the study, following collection of written informed consent from parents/guardians. Stool samples were tested for the presence of RV using enzyme immunoassay, and a random subset of RV-positive samples was further genotyped using reverse transcriptase-polymerase chain reaction and reverse hybridization assay. Results Of 314 enrolled children, 239 were included in the final analysis. RV was detected in 107 children (44.8%), mostly in the 6–23 months age group (82/107; 76.6%). RVGE occurred throughout the year, with the highest proportion occurring during April (26/42; 61.9%). G1P[8[ was the most commonly detected RV strain (10/17; 58.8%) in the limited number of samples analyzed. Vomiting and severe RVGE were more commonly observed in RV-positive than RV-negative children before hospitalization (P = 0.0008 and 0.0204, respectively). Conclusion In our study, RV accounted for over 40% of GE-associated hospitalizations and particularly affected children under 2 years of age. These data will serve as a baseline for assessing the potential changes in the epidemiology of RV disease and for evaluating the potential impact of the introduction of RV vaccination.

Abstract
BACKGROUND A substantial number of surveillance studies have documented rotavirus prevalence among children admitted for dehydrating diarrhea. We sought to establish global seasonal patterns of rotavirus disease before the introduction of widespread vaccination. METHODS We reviewed studies of rotavirus detection in children with diarrhea published since 1995. We assessed potential relationships between seasonal prevalence and locality by plotting the average monthly proportion of diarrhea cases positive for rotavirus according to geography, country development and latitude. We used linear regression to identify variables that were potentially associated with the seasonal intensity of rotavirus. RESULTS Among a total of 99 studies representing all 6 geographic regions of the world, patterns of year-round disease were more evident in low- and low-middle income countries compared with upper-middle and high-income countries where disease was more likely to be seasonal. The level of country development was a stronger predictor of strength of seasonality (P = 0.001) than geographic location or climate. However, the observation of distinctly different seasonal patterns of rotavirus disease in some countries with similar geographic location, climate and level of development indicate that a single unifying explanation for variation in seasonality of rotavirus disease is unlikely. CONCLUSION While no unifying explanation emerged for varying rotavirus seasonality globally, the country income level was somewhat more predictive of the likelihood of having seasonal disease than other factors. Future evaluation of the effect of rotavirus vaccination on seasonal patterns of disease in different settings may help understand factors that drive the global seasonality of rotavirus disease.

Abstract
BACKGROUND The contribution of platelets to the inflammatory response via several platelet derived mediators is well recognized. The role of mean platelet volume (MPV) in infectious and inflammatory disorders, however, has not yet been well-established. While some of the previous studies demonstrated that MPV acted as a positive acute phase reactant, several others suggested its role as a negative acute phase reactant. In the current study, we aimed to assess the role of MPV as an acute phase reactant in children with rotavirus gastroenteritis. METHODS We undertook a prospective, randomized, controlled, cross-sectional study and enrolled children diagnosed with acute rotavirus gastroenteritis and healthy controls (HC), between August and November 2012. Children with acute gastroenteritis were assigned either in the rotavirus-positive acute gastroenteritis (RPAG) or in the rotavirus-negative acute gastroenteritis (RNAG) group depending on their stool antigen results. Patients were also classified into two groups based on their Vesikari score (< 11: non-severe and ≥ 11: severe). Complete blood count and C-reactive protein (CRP) levels were assessed for all patients. We compared MPV between RPAG, RNAG and HC groups and investigated the association, if any, among MPV, platelets, white blood count and CRP. RESULTS In total 100 RPAG (54 males; mean age: 38.74 ± 41.45 months), 100 RNAG (58 males; mean age: 32.84 ± 29.64 months) children and 100 HC (43 males; mean age: 33.21 ± 32.55 months) were enrolled into the study. Mean platelet counts were well-matched among groups (p > 0.05). We observed a steady decline in MPV (fL) in the HC, RPAG and RNAG groups (median 7.80, 7.35 and 7.30, respectively; p < 0.0001). We did not find an association between MPV and the clinical score of gastroenteritis (p > 0.05). CONCLUSION We found that MPV could be used as an acute phase reactant in children with rotavirus gastroenteritis. We believe that the current study will contribute to our understanding of MPV as an inflammatory marker.

Estimating and comparing the clinical and economic impact of paediatric rotavirus vaccination in Turkey using a simple versus an advanced model. Vaccine 2012; 31:979-86. [PMID: 23219433 DOI: 10.1016/j.vaccine.2012.11.071] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2012] [Revised: 11/20/2012] [Accepted: 11/25/2012] [Indexed: 11/20/2022]
Abstract
BACKGROUND The burden of rotavirus disease is high in Turkey, reflecting the large birth cohort (>1.2 million) and the risk of disease. Modelling can help to assess the potential economic impact of vaccination. We compared the output of an advanced model with a simple model requiring fewer data inputs. If the results are similar, this could be helpful for countries that have few data available. METHODS The advanced model was a previously published static Markov cohort model comparing costs and quality-adjusted life-year (QALY) outcomes of vaccination versus no vaccination. In contrast, the simple model used only a decision tree. Both models included data on demography, epidemiology, vaccine efficacy, resource use, unit costs, and utility scores from national databases and published papers. Only the perspective of the health care payer was considered in the analysis. The simple model had 23 variables, compared with 103 in the advanced model to allow additional comparisons of different vaccine types, dose schemes and vaccine waning. RESULTS With the same input data, both models showed that rotavirus vaccination in Turkey would improve health outcomes (fewer QALYs lost to rotavirus disease). The projected annual cost offsets were $29.9 million in the simple and $29.4 million in the advanced model. Sensitivity analysis indicated that in both models the main cost driver was disease incidence followed by cost for hospital care and medical visits. Vaccine efficacy had a smaller effect. CONCLUSION Both models reached similar conclusions. Both projected that rotavirus vaccination in Turkey would improve health outcomes and may result in savings in direct healthcare costs to offset the cost of vaccination. The analysis indicated that the simple model can produce meaningful economic results in conditions where few data are available.

Abstract
Objectives. The aim of the study is to compare the clinical effectiveness of the probiotics—Saccharomyces boulardii and Bifidobacterium lactis—in children who had been diagnosed with rotavirus gastroenteritis. Materials and methods. Seventy five patients aged between 5 months–5 years diagnosed as rotavirus gastroenteritis were included in the study. The patients diagnosed as rotavirus gastroenteritis by latex agglutination test in stool were divided into 3 groups of twenty-five patients each: First group was given oral rehydration therapy and rapid refeeding with a normal diet with Saccharomyces boulardii (spp. I-745), second group was given oral rehydration therapy and rapid refeeding with a normal diet with Bifidobacterium lactis (spp. B94, culture number:N°118529) and third group received only oral rehydration therapy and rapid refeeding with a normal diet. Results. The duration of diarrhea was shorter in the group given oral rehydration therapy and rapid refeeding with a normal diet with Bifidobacterium lactis and Saccharomyces boulardii than the group given only oral rehydration therapy and rapid refeeding with a normal diet. Conclusion. Bifidobacterium lactis has a complemental role in the treatment of rotavirus gatroenteritis and other probiotics may also have a beneficial effect in rotavirus gastroenteritis compared with the therapy included only oral rehydration therapy and rapid refeeding with a normal diet.

Abstract
To describe the circulation dynamics of human rotavirus genotypes and to understand the epidemiological changes of rotavirus infection in Turkey, one of the countries where the highest mortality rates are seen due to rotavirus in Europe. Stool samples of children under 5 years of age which gave positive results for rotavirus antigen were stored at -20°C and then genotyped using multiplex reverse transcription polymerase-chain reaction. Of the 494 stool samples, 137 (28.1%) were positive for rotavirus antigen and 100 (73%) samples which could be genotyped successfully were included in the study. 42 (42%) samples were from inpatients, and 58 (58%) were from outpatients. The median age of the children was 16 months (5 days-59 months). G9 and P[8] were the most frequent G and P genotypes, and were detected in 30 (30%) and 55 patients (55%), respectively. In 90 samples for which both G and P genotypes could be determined, 34 different combinations were found. G9P[8] was the most frequent genotype detected in 19 patients (19%), followed by G1P[8] and G4P[6] each in 7 (7%) patients. The incidence of mixed infection was found to be 26%. Novel strains like P2A[6] and P[5] and unusual reassortant strains were detected. Distribution of rotavirus genotypes exhibited distinctive changes in this study. When the ever-changing epidemiology of rotaviruses is taken into account, ongoing surveillance studies are important before the inclusion of rotavirus vaccines in national immunization program of Turkey.

Abstract
Background Rotavirus gastroenteritis (RVGE) is the most common cause of severe childhood diarrhea worldwide. Objectives were to estimate the burden of RVGE among children less than five years old in the Middle East (Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Syria, UAE, Yemen), North Africa (Algeria, Egypt, Libya, Morocco, Tunisia) and Turkey. Methods A comprehensive literature search was conducted in major databases on the epidemiology and burden of rotavirus among children less than five years old between 1999 and 2009. Data from each country was extracted and compared. Results The search identified 43 studies. RVGE was identified in 16-61% of all cases of acute gastroenteritis, with a peak in the winter. RVGE-related hospitalization rates ranged from 14% to 45%, compared to 14%-28% for non-RVGE. Annually, RVGE caused up to 112 fatalities per 100,000 in certain countries in the region. Hospitalization costs ranged from $1.8 to $4.6 million annually, depending on the country. The most recent literature available showed that G1P[8] was the most prevalent genotype combination in 8 countries (range 23%-56%). G2P[4] was most prevalent in 4 countries (26%-48%). G9P[8] and G4P[8] were also frequently detected. Conclusions RVGE is a common disease associated with significant morbidity, mortality, and economic burden. Given the variety and diverse rotavirus types in the region, use of a vaccine with broad and consistent serotype coverage would be important to help decrease the burden of RVGE in the Middle East and North Africa.

Abstract
AbstractVaccines against rotaviruses are now available in numerous countries, including Turkey. As the vaccines may show various efficiencies against different type specificities and routine vaccination in infants might result in selection and immune escape of wild-type rotavirus strains, strain surveillance has been initiated before and during the vaccine introduction. We aimed to provide corresponding information on local strain prevalence in Anatolia, mid-western Turkey during the introduction of rotavirus vaccines. Stool samples positive for group A rotavirus by commercial enzyme immunoassay were subjected to reverse transcription-polymerase chain reaction based genotyping of the outer capsid antigens, VP7 and VP4, determining G and P type specificities respectively. Among 36 fully and 5 partially typeable strains we detected genotype G1, G2, and G9 VP7 specificities and genotype P[4], P[6] and P[8] VP4 specificities in 5 individual and 4 mixed combinations. The most common strain was G2P[4] (n=17), followed by G9P[8] (n=9). Other strains were G1P[8] (n=2), G2P[8] (n=2), G1+2P[8] (n=2), G9P[4] (n=1), G2+9P[8] (n=1), G4+9P[6] (n=1), and G2P[4+8] (n=1). Partially typed strains included 2 G1P[NT] and 3 G2P[NT] strains. Our data may help determine a baseline of the rotavirus genotype prevalence in Turkey and see if changes in the incidence of individual strains will be observed after routine use of vaccine.

Abstract
BACKGROUND Diarrhea is the third leading cause of death related to infectious diseases all over the world. The diseases related to viral gastroenteritis are gradually increasing, particularly in the developed countries. The purpose of our study was to determine the frequency and to investigate the clinical manifestations of acute rotavirus and adenovirus gatroenteritis and to assess the diagnostic value of the related clinical findings. METHODS In 2007-2008 patients with diarrhea and/or vomiting attended to Yeditepe University Hospital and related clinics, Istanbul, were studied. The rotavirus and/or adenovirus antigen in stool of these patients were investigated. Data regarding clinical findings were collected from the electronic records, retrospectively. Age, gender, symptoms, fever, antibiotic use, vomiting, number of vomiting and diarrhaeae, dehydration, abdominal pain, the other pathological physical examination findings were analyzed by the physicians in the study group. To investigate the rotavirus and adenovirus antigen CerTest Rota-Adeno Blister Test (CerTest, Biotec, Spain), a qualitative immunochromotographic assay was used. Statistical analysis wasperformed with SPSS v. 11,5 statistical software. X2 test was used for bivariate and logistic regression analysis was used for multivariate analysis. RESULTS Rotavirus positivity was 18,7% (n = 126). Concomitantly, in 596 cases adenovirus antigen test were also performed. Adenovirus positivity was 8,9% (n = 53) and rota-adenovirus co-infection was 4,4% (n = 26). Most of rotavirus positive cases were seen in December, January, February and March (p < 0.001). In clinical parameters, there was a significant difference between rotavirus positive cases and negative cases regarding to vomiting, dehydration and vomiting and diarrhea coexistence (respectively p = 0.010, p < 0.00, p = 0.007). CONCLUSION Rotavirus can be seen in all age groups, but more frequently in childhood. Although there is no clinical gold standard to distinguish the rotavirus cases from the other gastroenteritis agents, the findings of dehydration and vomiting-diarrhea coexistence, considering months of referral may lead clinician to perform rapid antigen tests and affect approach to the treatment. Prospective studies with representative samples are needed to determine the rotavirus and adenovirus incidence and to develop safe and reliable protective policies in our country.

Abstract
SUMMARYIn 2006 two rotavirus vaccines were licensed for use in young children in Europe. This study aimed to estimate the mortality and hospital admissions due to rotavirus in children aged <5 years in the WHO European region using data from routine sources and published literature. We grouped 49/52 countries in the region by their World Bank Gross National Income (GNI) per capita. We obtained for children aged <5 years: populations, hospital discharges for diarrhoeal disease, estimated mortality rates and the percentage of deaths attributable to diarrhoeal disease, from WHO data sources or published literature, and combined them to estimate country-specific diarrhoeal disease mortality. Rotavirus-attributable percentages of hospital admissions due to diarrhoeal disease were obtained through a literature search, and an income-group median applied to countries in each GNI category. In the countries we studied in the WHO European region, rotavirus infection causes an estimated 6550 deaths (range 5671–8989) and 146 287 (range 38 374–1 039 843) hospital admissions each year in children aged <5 years. Hospital admission rates were similar across income groups (medians 2·0, 2·8, 4·2 and 1·9/1000 per year in low-, lower-middle-, upper-middle- and high-income countries, respectively). Seven countries, mostly in the low- and lower-middle-income groups, accounted for 93% of estimated deaths. Disease burden varied dramatically by income level in the European region. Rotavirus vaccination in Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan and Turkey could potentially prevent 80% of all regional rotavirus deaths. Data from low-income countries is still sparse, and improved disease burden studies are required to better inform regional vaccine policy.

Rotavirus fecal antigen retrieval in infantile intussusception. Eur J Clin Microbiol Infect Dis 2008; 27:879-81.

Abstract
This study was designed to assess the plausibility of an association between natural rotavirus infection and intussusception. It was conducted on 21 infants suffering from acute gastroenteritis (GE) complicated by intussusception who were compared to another 40 age- and sex-matched infants suffering from acute GE characterized by watery nonmucoid diarrhea without surgical complications. All enrolled patients were subjected to detailed history documentation, thorough clinical examination and laboratory investigations, complete stool analysis, and detection of rotavirus antigen in stools using the ELISA technique. Plain abdominal X-ray and ultrasound were also performed. The results of this study revealed 24 positive cases for rotavirus antigen in the stools of the acute uncomplicated GE patients (60.0%), while there were only ten positive cases in the intussusception group (47.6%). No significant difference in severity was detected between the two groups studied, especially in terms of signs of dehydration and need for IV fluids (p > 0.05). Most of the rotavirus positive cases among the intussusception group presented either in February or December (p < 0.05) with no significant seasonal pattern among the acute GE group (p > 0.05). In conclusion, rotavirus antigen retrieval from stools of GE patients complicated with intussusception was not statistically different from those detected among acute uncomplicated GE. Additionally, there was no association between seasonality or severity of rotavirus positive cases in acute GE patients and those with intussusception. It is thus prudent to say that wild rotavirus infection in GE patients does not carry an extra risk for the occurrence of intussusception.

Abstract
Of 260 children with acute diarrhea in Erbil, Iraqi Kurdistan, 96 (37%) were infected with rotavirus. Reverse transcription-polymerase chain reaction identified G1, G4, G2, G9, P[8], P[6], and P[4] as the most common genotypes. Eight G/P combinations were found, but P[8]G1 and P[4]G2 accounted for >50% of the strains.
