Rare Cause of Hematochezia in Children: Solitary Rectal Ulcer, Single Center Experience.

Background/Aims: Solitary rectal ulcer syndrome (SRUS) can be overlooked, diagnosed late, or misdiagnosed, particularly in childhood. This study reviewed the 13-year experience of the authors' institution to increase clinicians' awareness of SRUS in the presence of symptoms. This paper reports the endoscopic and histopathological findings in children presenting with hematochezia. Methods: The clinical and laboratory findings of 22 patients diagnosed with biopsy-proven SRUS in the authors' clinic between 2007 and 2020 were evaluated retrospectively. Results: The mean age at diagnosis was 12.5±2.6 years, and 59.1% of the patients were male. The median time of diagnosis was 24 months. A single ulcer lesion was found by colonoscopy in 18 patients (81.8%), two ulcers in two patients (9%), and more than two ulcers in two patients (9%). The pathology reports of all biopsies taken from the lesions were consistent with a solitary rectal ulcer. In the first stage, the treatment was started with toilet training, a high-fiber diet, and laxatives. In 11 patients (50%) who did not respond to the initial treatment, a 5-ASA enema was added. A glucocorticoid enema was added to treatment in five patients (22%) whose complaints did not regress despite this treatment. Clinical remission was achieved in five of the patients (18.1%). The time to diagnosis was significantly shorter in those in remission than those not in remission (p=0.04). Conclusions: This study is the first large series on Turkish children. An increased awareness of SRUS in children will increase the rate of early diagnosis and treatment, allowing remission in more patients.

The frequency of Duchenne muscular dystrophy/Becker muscular dystrophy and Pompe disease in children with isolated transaminase elevation: results from the observational VICTORIA study.

Introduction: Elevated transaminases and/or creatine phosphokinase can indicate underlying muscle disease. Therefore, this study aims to determine the frequency of Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) in male children and Pompe disease (PD) in male and female children with isolated hypertransaminasemia. Methods: This multi-center, prospective study enrolled patients aged 3-216 months with serum alanine transaminase (ALT) and/or aspartate transaminase (AST) levels >2× the upper limit of normal (ULN) for ≥3 months. Patients with a known history of liver or muscle disease or physical examination findings suggestive of liver disease were excluded. Patients were screened for creatinine phosphokinase (CPK) levels, and molecular genetic tests for DMD/BMD in male patients and enzyme analysis for PD in male and female patients with elevated CPK levels were performed. Genetic analyses confirmed PD. Demographic, clinical, and laboratory characteristics of the patients were analyzed. Results: Overall, 589 patients [66.8% male, mean age of 63.4 months (standard deviation: 60.5)] were included. In total, 251 patients (188 male and 63 female) had CPK levels above the ULN. Of the patients assessed, 47% (85/182) of male patients were diagnosed with DMD/BMD and 1% (3/228) of male and female patients were diagnosed with PD. The median ALT, AST, and CPK levels were statistically significantly higher, and the questioned neurological symptoms and previously unnoticed examination findings were more common in DMD/BMD patients than those without DMD/BMD or PD (p < 0.001). Discussion: Questioning neurological symptoms, conducting a complete physical examination, and testing for CPK levels in patients with isolated hypertransaminasemia will prevent costly and time-consuming investigations for liver diseases and will lead to the diagnosis of occult neuromuscular diseases. Trial Registration: Clinicaltrials.gov NCT04120168.

The significance of MUAC z-scores in diagnosing pediatric malnutrition: A scoping review with special emphasis on neurologically disabled children.

This review by a panel of pediatric gastroenterology-hepatology-nutrition and pediatric neurology experts aimed to address the significance of mid-upper arm circumference (MUAC) assessment in diagnosis of pediatric malnutrition. Specifically, the potential utility of recently developed MUAC z-score tape in clinical practice for larger patient populations was addressed including the neurologically disabled children. In accordance with the evidence-based data, four statements were identified by the participating experts on the utility of MUAC z-score tape, including (1) MUAC z-scores correlate with body mass index (BMI) and weight for height/length (WFH/l) z-scores in diagnosing malnutrition; (2) MUAC z-score tape offers a higher sensitivity to diagnose the mild and moderate malnutrition and better ability to track the changes in nutritional status over time than the other single datapoint measurements; (3) Using single-step MUAC z-score tape in children with cerebral palsy (CP) seems to provide more reliable data on anthropometry; and (4) The clinical value of the tool in classifying secondary malnutrition in CP should be investigated in large-scale populations. In conclusion, enabling single-step estimation of nutritional status in a large-scale pediatric population regardless of age and within a wide range of weight, without formal training or the need for ancillary reference charts and calculators, MUAC z-tape offers a favorable tool for easier and earlier diagnosis of pediatric malnutrition. Nonetheless, further implementation of MUAC z-score screening in larger-scale and/or special populations is necessary to justify its utility in relation to other primary anthropometric indicators in diagnosis of malnutrition as well as in treatment monitoring in the community and hospital setting.

Factors Associated with Low Bone Mineral Density at the Time of Diagnosis in Children with Celiac Disease

Objective: It has been reported that bone mineral density (BMD) is decreased in children with Celiac disease (CD) compared to their healthy peers. The aim of this study was to reveal possible risk factors for low BMD in Turkish children newly diagnosed with CD. Methods: Eighty-six patients (2-18 years old) with CD were included in this retrospective study. The relationship between their lumbar BMD z-scores calculated according to their chronological age (CA) and height age (HA) and their clinical, laboratory [biochemical parameters, tissue transglutaminase antibody-IgA (TTGA) levels, human leukocyte antigen (HLA) types] and histopathological parameters were evaluated. Results: The mean age of the patients at diagnosis was 8.06±4.08 years. The BMD z-score CA was ≤-2 standard deviation (SD) in 26.7% of the patients. The BMD z-score HA was ≤-2 SD in 12.8% of the patients. The BMD z-score HA only correlated with their age at diagnosis of CD (rs value 0.269). However, there was no statistically difference between the BMD z-score HA >-2 SD and ≤-2 SD subgroups regarding their clinical, laboratory and histopathological parameters. Conclusion: Low BMD is common in children with newly diagnosed CD. Age at diagnosis, gender, body size, Celiac symptoms, biochemical parameters, TTGA level, HLA type, and histopathological stage had no predictive values in terms of low BMD in this patient group.

Is There a Predictive Factor for an Association with Autoimmune Glandular Disease in Children Diagnosed with Celiac Disease?

Objective: A close relationship has been suggested between Celiac disease (CD) and glandular autoimmunity. The aim of this study was to determine the predictive factors for autoimmune glandular disease (AGD) in children with CD. Methods: The study included 228 pediatric patients, diagnosed with CD between 2010 and 2019. The cases with AGD (Group 1) and those without AGD (Group 2) and the patients with type 1 diabetes mellitus (T1DM) (Group A) and those without T1DM (Group B) were retrospectively reviewed and compared in terms of clinical and laboratory features. Results: AGD was detected in 8.8% (n=20) of the patients: T1DM in 13 (65%), T1DM and Hashimoto's thyroiditis (HT) in 3 (15%), HT only in 2 (10%), T1DM and Graves disease (GD) in 1 (5%), and GD only in 1(5%). The mean age at the diagnosis of CD was significantly higher in Group 1 (10.93±4.15 years) compared to Group 2 (8.10±4.19 years) (p<0.05) and also was significantly higher in Group A compared to Group B (p<0.05). Most of the diagnoses of AGD were made before the diagnosis of CD and age was an effective factor. There was no difference between Group 1 and Group 2 and Group A and Group B in terms of gender, typical/atypical CD ratio, tissue transglutaminase IgA (TTGA) level, human leucocyte antigen (HLA)-DQ2 and/or HLA-DQ8 positivity rate, and histopathological stage. Conclusion: Although patients with a diagnosis of co-existent CD and AGD were significantly older than patients with isolated CD, gender, celiac symptoms, TTGA level, HLA type, and histopathological stage had no predictive value for the coexistence of AGD in patients with CD.

Recommendations for Clinical Decision-making in Children with Type 1 Diabetes and Celiac Disease: Type 1 Diabetes and Celiac Disease Joint Working Group Report

It is well-known that in children with type 1 diabetes (T1D), the frequency of Celiac disease (CD) is increased due to mechanisms which are not fully elucidated but include autoimmune injury as well as shared genetic predisposition. Although histopathologic examination is the gold standard for diagnosis, avoiding unnecessary endoscopy is crucial. Therefore, for both clinicians and patients' families, the diagnosis of CD remains challenging. In light of this, a joint working group, the Type 1 Diabetes and Celiac Disease Joint Working Group, was convened, with the aim of reporting institutional data and reviewing current international guidelines, in order to provide a framework for clinicians. Several controversial issues were discussed: For CD screening in children with T1D, regardless of age, it is recommended to measure tissue transglutaminase-immunoglobulin A (tTG-IgA) and/or endomysial-IgA antibody due to their high sensitivity and specificity. However, the decision-making process based on tTG-IgA titer in children with T1D is still debated, since tTG-IgA titers may fluctuate in children with T1D. Moreover, seronegativity may occur spontaneously. The authors' own data showed that most of the cases who have biopsy-proven CD had tTG-IgA levels 7-10 times above the upper limit. The decision for endoscopy based solely on tTG-IgA levels should be avoided, except in cases where tTG-IgA levels are seven times and above the upper limit. A closer collaboration should be built between divisions of pediatric endocrinology and gastroenterology in terms of screening, diagnosis and follow-up of children with T1D and suspicious CD.

Single-center experience in management of progressive familial intrahepatic cholestasis.

BACKGROUND AND STUDY AIMS: Progressive familial intrahepatic cholestasis (PFIC) is an autosomal recessively inherited disease that causes intrahepatic-hepatocellular cholestasis. PFIC constitutes approximately 10-15% of cholestatic liver diseases in children. The aim of this study is to draw attention to this group of diseases, which pose a higher risk, in societies where consanguineous marriage is more common, and to share our experiences since the studies in the literature, regarding this group of diseases are case series with small number of patients. PATIENTS AND METHODS: This cross-sectional study was conducted on 34 patients who were admitted with jaundice and diagnosed by genetic analysis, between January 2015 and July 2020. RESULTS: We found 17.6% of patients with PFIC type 1, 55.9% patients had PFIC type 2, 14.7% patients had PFIC type 3, 8.8% patients had PFIC type 4 and 2.9% patients had PFIC type 5. Partial internal biliary diversion was performed in 5 (14.7%) patients, who had severe itching during follow-up, did not respond to medical treatment, and did not have significant fibrosis in liver biopsy yet. The degree of itching before PIBD was rated as +4 (cutaneous erosion, bleeding and scarring), in 5 patients and the rates were 0 (absent) in two patients, and +1 (mild itching) in 3 patients, 6 months after PIBD, these differences were statistically significant(p = 0.027). The mean weight z score was-1.43 (-3.72-+0.73), before PIBD, while it was 0.39(-1.86 -+2.45), six months after PIBD; the diference was statistically significant(p = 0.043). Liver transplantation was performed in 12 (35.3%) patients with significant fibrosis in liver biopsy and developing signs of portal hypertension. CONCLUSION: The PFIC disease group is a heterogeneous disease group that is difficult to diagnose and treat. It should be considered in patients with cholestasis and/or pruritus and those with a history of consanguineous marriage between parents and death of a sibling with similar clinical symptoms.

Nutritional Support in Malnourished Children With Compromised Gastrointestinal Function: Utility of Peptide-Based Enteral Therapy.

This review focuses on nutritional support in malnourished children with compromised gastrointestinal function addressing the interplay between malnutrition and gastrointestinal dysfunction, and the specific role of peptide-based enteral therapy in pediatric malnutrition. Malnutrition is associated with impaired gut functions such as increased intestinal permeability, malabsorption, and diarrhea, while pre-existing functional gastrointestinal disorders may also lead to malnutrition. Presence of compromised gastrointestinal function in malnourished children is critical given that alterations such as malabsorption and increased intestinal permeability directly interfere with efficacy of nutritional support and recovery from malnutrition. Appropriate nutritional intervention is the key step in the management of malnutrition, while alterations in gastrointestinal functions in malnourished children are likely even in those with mild degree malnutrition. Therefore, nutritional therapy in children with compromised gastrointestinal function is considered to involve gut-protective interventions that address the overlapping and interacting effects of diarrhea, enteropathy and malnutrition to improve child survival and developmental potential in the long-term. Peptide-based enteral formulas seem to have clinical applications in malnourished children with compromised gastrointestinal function, given their association with improved gastrointestinal tolerance and absorption, better nitrogen retention/ balance, reduced diarrhea and bacterial translocation, enhanced fat absorption, and maintained/restored gut integrity as compared with free amino acid or whole-protein formulas.

Infection risk after paediatric liver transplantation.

Infections after liver transplantation (LT), despite prophylactic therapy, are still important causes of morbidity and mortality in children. Although underlying disease and immunosuppression along with the complexity of LT procedure are the major predispositions to infections, there still might be under recognised factors predisposing infections in paediatric LT. In this study, we retrospectively analysed the risk factors of bacterial, viral, and fungal infections after LT in a series of 167 children (median =5 yr.). Of all children, 112 (67%) experienced infections: 93 (55.7%) bacterial, 56 (33.5%) viral and 15 (9%) fungal. Multilogistic regression analysis showed that the need of immunosuppressive switch increased total, bacterial, and viral infection risk 5.3, 2.5, and 2.5 times, respectively, (p=0.001, p=0.021, and p=0,019, respectively). Re-LT increased bacterial infection risk 4.2 times (p=0.040). Viral infection risk was 10 times higher in children who had more than two re-laparotomies (p=0,002). Children who had post-LT, cytomegalovirus (CMV) infection had 5.6 times increased risk for fungal infection (p=0.035). In conclusion, infection is still an important morbidity in paediatric LT and is in close relationship with other morbidities such as surgical complications. CMV infection, itself, is an independent risk factor for fungal infection.

The effects of iron and zinc status on prognosis in pediatric Wilson's disease.

OBJECTIVES: Wilson's disease (WD) is a metabolic disorder leading to hepatic and extrahepatic copper deposition. Several studies have reported that besides copper (Cu), iron (Fe) and zinc (Zn) are also accumulated at varying levels in various tissues in WD. However, there is not an adequate number of studies investigating the effects of Fe and Zn status on WD presentation and prognosis. We aimed to evaluate serum levels of ferritin (SFr), copper (SCu), and zinc (SZn) in WD and determine their role in disease presentation and prognosis. MATERIALS-METHOD: We retrospectively reviewed the medical records of 97 pediatric patients with WD who were diagnosed and followed at Inönü University Pediatric Gastroenterology, Hepatology and Nutrition Department between January 2006 and May 2017. Serum Cu and Zn levels were analyzed by using flame atomic absorption spectrophotometer. Ferritin was analyzed by chemiluminescence immunoassay method. RESULTS: Analysis of serum levels of the elements according to the type of presentation, there was no significant difference between the groups for ceruloplasmin. However, SCU, FSCu, SFr and 24 h urinary copper levels were significantly higher (p = 0.002, p = 0.003, p = 0.023 and p < 0.001, respectively) and SZn and CSZn levels were significantly lower (fulminant WD). p < 0.001, p < 0.001). There was a positive correlation between SFr, SCu serum levels and mortality scores (respectively, r: 0.501, 0.564 for PELD, r:0.490, 0.504 for MELD, r: 0.345, 0.374 for Dhwan), and a negative correlation between SZn level and mortality scores. (r:-0.650 for PELD, r:-0.703 for MELD, r:-0.642 for Dhwan) We used the ROC curves to determine the worst prognosis for fulminant Wilson disease. According to these limit values, we found that the sensitivity and specificity of FWD development was significantly higher. (for SZn sensitivity of 91.5%, a specificity of 100%, p=<0,001, for SCu predicted FWD development with a sensitivity of 100%, a specificity of 73.7%, p=<0,001, for SFr predicted FWD development with a sensitivity of 92.9%, a specificity of 66.2%, p < 0,001) CONCLUSION: Our study suggests that SFr, SCu, SZn levels might have prognostic importance for WD.

Nutritional assessment of children with Wilson's disease: single center experience.

AIM: Nutritional status was accepted as a prognostic marker in children with chronic liver disease. In the literature, we aimed to retrospectively investigate 94 Wilson patients followed in our center due to the lack of studies investigating the frequency and prognostic effects of malnutrition and micronutrient deficiency in Wilson's patient. MATERIAL AND METHODS: Our studies included 94 Wilson's disease children in the Department of Child Gastroenterology, Hepatology and Nutrition of Inonu University Faculty of Medicine between 2006-2017. Presentation patterns, anthropometric measurements, laboratory findings and prognostic factors of these patients were analyzed retrospectively. RESULTS: The mean age of the patients was 9.11±3.2 (3.5-17) and the female/male ratio was 40/54. Mean age was lower in asymptomatic patients (p=0.000). According to all parameters, malnutrition was detected in 43 patients (45.7%). Fulminant Wilson's disease had higher height and weight z scores than nerowilson patients (p=0.045, p=0.019, respectively). Hypocalcemia, hypophosphatemia, hypouricemia, hypoalbuminemia and anemia were more common in patients with cholestasis than without cholestasis (p<0.001). Vitamin A and E are lower in patients with cholestasis than without cholestasis (p<0.05). Hypocalcemia, hypophosphatemia and hypo-uricemia were found higher in the fulminant group (p<0.001). According to mortality scores (Dhawan, Model for end-stage liver disease and Child-Pugh). In patients with high mortality, height Z score was found to be high (p<0.05). CONCLUSION: In Wilson's disease assessment of growth, detailed anthropometric measurements as well as vitamin, trace elements and electrolytes should be closely monitored.

Pediatric Wilson's disease: findings in different presentations. A cross-sectional study.

BACKGROUND: Wilson's disease (WD) may present with different manifestations: from an asymptomatic state to liver cirrhosis. Here, we aimed to evaluate clinical presentations and laboratory findings and prognoses among WD cases. DESIGN AND SETTING: Cross-sectional study based on patients' records from the university hospital, Inönü University, Malatya, Turkey. METHODS: The medical records of 64 children with WD were evaluated focusing on the clinical, laboratory and liver biopsy findings in different clinical presentations. RESULTS: The mean age at diagnosis was 8.6 ± 3.26 years (range 3.5-17) and mean length of follow-up was 2.49 years (range 0-9). There were 18 cases (28.1%), 12 (18.8%), 9 (14.1%) and 6 (9.4%) of chronic liver disease, fulminant liver failure, neurological WD and acute hepatitis, respectively. Nineteen (29.7%) were asymptomatic. The most common sign and laboratory finding were jaundice (45.3%) and hypertransaminasemia (85.9%), respectively. The lowest serum zinc level was found in the fulminant liver failure group (P = 0.035). Hepatosteatosis was detected in 35% of the 20 patients who underwent liver biopsy. Among those with hepatosteatosis, 57.1% were asymptomatic. While 35% had copper staining, 25% presented iron accumulation in liver biopsies. Nine cases underwent liver transplantation and seven of these presented fulminant liver failure (77.8%). CONCLUSION: The presentation, symptoms and signs of our cases were similar to those in previously reported series, except for the high proportion of fulminant WD cases. Further studies are needed to clarify the relationship between zinc levels and development of a fulminant course and between iron status and WD.

Plasma Leptin, Adiponectin, Neuropeptide Y Levels in Drug Naive Children With ADHD.

OBJECTIVE: ADHD is one of the most common childhood psychiatric disorders. Research indicates that there is some link between obesity/overweight and ADHD, though the mechanism of this association remains uncertain. It is the aim of the present study to explore the association between ADHD, obesity, and plasma leptin, neuropeptide Y (NPY), and adiponectin levels. METHOD: Thirty-six patients diagnosed with ADHD were included in the study. The control group consisted of 40 healthy children and adolescents who had similar age and gender features with the patient group. Plasma leptin, adiponectin, NPY levels were measured, and body mass index (BMI), weight for height, and standard deviation scores (SDS) of height, weight, and BMI were calculated. RESULTS: No significant difference was found between patients and healthy children in terms of BMI and BMI percentile. Participants were classified into three groups according to their weight to height values. There was no significant difference between the two groups, but 10% of the control group and 30.6% of the ADHD group were classified as overweight, which was 3 times higher than the control group. The adiponectin plasma level was significantly lower and leptin/adiponectin (L/A) ratio was significantly higher in the ADHD group. There was no significant difference between serum NPY levels. In the ADHD group, the mean leptin plasma level was high, but was not statistically significant. CONCLUSION: We think that a low adiponectin level and high L/A ratio may be the underlying mechanism of the obesity in ADHD patients.

Torsion of a wandering spleen in an adolescent with Gaucher disease.

A wandering spleen is a rare condition characterized by the malposition of the spleen due to laxity or absence of its supporting ligaments. Although Gaucher disease generally presents with massive splenomegaly, which one of the predisposing causes of a wandering spleen, literature shows only one report of a wandering spleen in a child with Gaucher disease. In this case presentation, a 13-year-oldadolescent with Gaucher disease on enzyme replacement treatment was presented, who was detected having an abdominal mass on a routine visit and diagnosed with partial torsion of a wandering spleen associated with left lobe hypoplasia of the liver.

Seizures in Pediatric Patients With Liver Transplant and Efficacy of Levetiracetam.

The aim of this study was to evaluate the risk factors, clinical implications, and prognosis of new-onset seizures that occurred after pediatric liver transplantation, and to assess the efficacy of levetiracetam treatment. The clinical and laboratory data of liver transplanted 28 children who had seizures after liver transplantation and specifically of 18 children who received levetiracetam were analyzed retrospectively. Sixteen patients (88.9%) remained seizure-free and in 2 (11.1%), more than 50% reduction in seizures were detected with levetiracetam treatment. In conclusion, seizures are generally the most common complication by a spectrum of seizure types, and sometimes cause symptomatic epilepsy. The most common risk factors for seizures in transplant recipients is immunosuppressant toxicity. Currently, there isn't a specific treatment involving the transplant patient population. Levetiracetam may be preferable in pediatric patients as it's reliable for liver disease and has advantages in the treatment of postoperative seizures due to its intravenous usage.

Evaluation of renal functions in pediatric liver transplantation.

AKI is an important complication after LT. As our LT series contains a quite high number of children with ALF unlike published studies, we aimed to determine pre-LT and long-term renal functions in children both with ALF and with CLD. Demographic and disease-related data of 134 transplanted children were evaluated retrospectively. Pre-LT and follow-up GFR and pediatric RIFLE scores were determined. Mean pre-LT GFR was not dependent on the disease presentation or severity of chronic disease. While there was an initial decline until first week of post-LT in CLD children, an increase was observed in ALF. Neither mean GFR nor the pRIFLE on follow-up was different with respect to the type of LT or disease presentation. Mean GFR at first and sixth months were lower in children on cyclosporine compared to tacrolimus (p = 0.001 and p = 0.002, respectively). In conclusion, GFR-time curve was different in children with or without ALF. Type of LT, and severity of the CLD were not risk factors for CKD in any time, but younger age at LT, CLD, and cyclosporine usage were at sixth months of follow-up.

Malnutrition and Obesity in Children With ADHD.

OBJECTIVE: Low threshold of dissatisfaction and frustration in child and adolescent patients with ADHD lead to changes in dietary pattern with contribution to the development of obesity and other nutritional disorders. METHODS: A total of 362 patients with the diagnosis of ADHD and 390 children without any chronic disease were included to the study. We evaluated the anthropometric measurements for all cases. RESULTS: The overweight/obese cases according to weight for height (WFH) and body mass index scores were more likely in ADHD cases than control group. Malnourished cases according to WFH were more common in ADHD cases. Patients with weight standard deviation scores between <-2 and >2 were significantly higher in ADHD cases than the control group patients. CONCLUSION: Frequency of malnutrition and overweight/obese patients was found higher in ADHD cases compared with control group, and this situation suggested that ADHD is a risk factor for the development of eating disorders.

Eight different viral agents in childhood acute gastroenteritis.

Viral gastroenteritis is the most frequent cause of acute gastroenteritis (AGE) of childhood. The aim of this study was to determine the prevalence of viral agents including astrovirus, rotavirus, adenovirus, enterovirus, norovirus, parechovirus, Aichivirus and sapovirus in children with AGE in a pediatric Turkish population. Fecal specimens of 240 children with AGE were investigated by polymerase chain reaction, and viral agents were identified in 131 (54.6%) samples. The distribution of viral agents was as follows: 56 (42.8%) norovirus, 44 (33.6%) rotavirus, 29 (22.1%) enterovirus, 21 (16.0%) adenovirus, 21 (16.0%) parechovirus, 5 (3.8%) sapovirus and 1 (0.8%) Aichivirus. Single and multiple viral agents were detected in 38.8% and 15.8% of patients, respectively. The duration of hospitalization was longer in children with multiple viral agents than in those infected with a single viral agent (p<0.001). While the highest rate of rotavirus infection was detected in winter, the highest rate of norovirus was found in the summer. In conclusion, norovirus and rotavirus are the most frequent causes of childhood AGE in our country.
