Molecular Detection of Sapovirus in Children Under Five Years with Acute Gastroenteritis in Mansoura, Egypt between January 2019 and February 2020

Background: Sapovirus has emerged as a viral cause of acute gastroenteritis. However, there is limited data on sapovirus in Egypt. . The present study aimed to evaluate the presence of sapovirus in children with acute gastroenteritis <5 years in Mansoura, Egypt from January 2019 to February 2020 by reverse transcriptase-polymerase chain reaction (RT-PCR). Methods: The cross-sectional study enrolled a 100 children <5 years who presented with acute gastroenteritis at an outpatient clinic in Mansoura, Egypt between January 2019 and February 2020. Clinical data, demographic data and a stool sample was collected from each child. Stools were screened by microscopy for parasites and culture methods for bacteria and excluded from the study if positive for either. Specimens were also screened for rotavirus by enzyme immune assays (EIA) and sapovirus by reverse transcription PCR. Results: The most frequently detected virus was rotavirus by ELISA 25% (25/100). RT-PCR detected sapovirus in 7% (7/100) of the stool samples. The children with sapovirus were all from rural regions and presented mainly during the winter season in Egypt 42.9% (3/7). The main presenting symptoms were fever 71.4% (5/7) and vomiting 57.1% (4/7). None of the children with sapovirus had dehydration. Rotavirus was significantly associated with sapovirus infections in five samples (5/7) , 71.4%, P=0.01. Conclusion: The present study highlights the emergence of sapovirus as a frequent pathogen associated with acute gastroenteritis in children. There is a need for a national survey program for the study of sapovirus among other pathogens associated with acute gastroenteritis for better management of such infection.

Background: Sapovirus has emerged as a viral cause of acute gastroenteritis. However, there are insufficient data about the presence of this virus among children with acute gastroenteritis. The present study aimed to evaluate the presence of sapovirus in children with acute gastroenteritis by reverse transcriptase-polymerase chain reaction (RT-PCR). Methods: A cross-sectional study enrolled 100 children patients with acute gastroenteritis from outpatient clinics with excluded bacterial pathogens and parasitic infestation. A stool sample was collected from each child for laboratory examination. Each stool sample was subjected to study by direct microscopic examination, study for rotavirus by enzyme-linked immunoassay (ELISA) and the remaining sample was subjected to RNA extraction and RT- PCR for sapovirus. Results: The most frequently detected virus was rotavirus by ELISA (25%). RT-PCR detected sapovirus in 7% of the stool samples. The children with sapovirus were all from rural regions and presented mainly during the winter season in Egypt (42.9%). The main presenting symptoms were fever (71.4%) and vomiting (57.1%). None of the children with sapovirus had dehydration. Rotavirus was significantly associated with sapovirus infections in 5 patients (71.4%, P=0.01). There was an insignificant difference between symptoms of gastroenteritis in children with sapovirus and children with gastroenteritis without sapovirus as regards vomiting (P=0.7), fever (P=0.46), and abdominal pain (P=0.69). Conclusion: The present study highlights the emergence of sapovirus as a frequent pathogen associated with acute gastroenteritis in children. There is a need for a national survey program for the study of sapovirus among other pathogens associated with acute gastroenteritis for better management of such infection.

Aim: To explore the prevalence of rotavirus infection along with the molecular detection and genotyping of group A rotavirus (RVA) among bovine calves up to 5 months old in Diyala province-Iraq. Methods: This is a cross sectional study conducted in Diyala province-Iraq during the period of 2019-2020. One hundred bovine calves with age range of 1-5 months were included in the study. All were suffering acute gastroenteritis. Serum anti-rotavirus IgM and IgG plus fecal rotavirus Ag were tested for using ELISA techniques. Stool samples positive for rotavirus Ag were submitted for reverse transcription PCR (RT-PCR) for G and P genes, followed by sequencing and genotyping thereafter. Statistical analysis was done using SPSS version 25 and P values ≤ 0.05 were considered significant. Results: The positivity rate of anti-rotavirus IgM was 80% (P = 0.0001), and that of anti-rotavirus IgG was 79% (P = 0.0001). The rotavirus stool antigen was detected in 68% of calves (P = 0.01). A total of 45 stool samples which were positive for rotavirus Ag were submitted for RT-PCR; 13 (28.9%) were positive and 32 (71.1%) were negative (P = 0.084). 10 PCR positive samples were used for sequencing and genotyping and indicated that all investigated strains belonged to G1P[8] genotype. Conclusion: The current strains analyzed belonged to the G1P[8] RVA genotypes, affirming that employment of VP7 gene polymorphism accurately yielded uniform phylogenetic distances amongst investigated rotavirus strains and that there were no noticeable assortment events between human and animal rotavirus strains in Diyala province.

AbstractBackgroundNeurological disability associated with multiple sclerosis and immunosuppressive or immunomodulatory therapy which is administered for it may increases the risk of SARS-CoV-2 infection and its morbidity/mortality.ObjectiveIn this study, we evaluated the infection rate and the severity of SARS-CoV-2 infection in patients with multiple sclerosis (MS)MethodsOne thousand and three hundred and sixty one MS patients from Fars province, south of Iran, were interviewed by phone from April 3 to June 20, 2020. Basic demographic data, information about MS disease and any symptoms or laboratory results relevant to COVID-19 were gathered and reviewed by treating neurologist and MS nurses. SPSS version 22 was used for data analysis.Results68 (5%) of MS patients were suspected cases and 8 (0.58%) of all patients with positive real-time reverse transcription polymerase chain reaction (RT-PCR) or chest CT were in the confirmed group. 5 cases of the confirmed group needed hospitalization. Two patients died while both of them had PPMS and were taking rituximab. The frequency rate of suspected cases with RRMS was 57 (87.7%), followed by PPMS 5 (7.7%) and CIS 2(3.1%). In the confirmed group 37.5% had RRMS, 50% had PPMS, 25% use corticosteroid drug, and 50% were on rituximab. 62.5% of confirmed cases had high disability level and need assistance to walk. 36.8% of suspected and 25% of the confirmed cases were on IFN-β1; eventually all of them recovered well from COVID-19 infection.ConclusionThe present study showed that rate of developing COVID-19 in MS patients are similar to the general population and the frequency of PPMS phenotype, rituximab therapy and corticosteroid therapy were higher in the confirmed group.

Abstract Background Organophosphates are one of the most common agents of poisoning in developing countries including Egypt. Due to lack of data about characteristics of organophosphates poisoning in our localities, we aimed to evaluate its clinical pattern and factors affecting outcome. Methods It was a cross-sectional study conducted in South valley University hospital between January 2019 and December 2019. It included all children ≤16 years of age presented with organophosphates poisoning. Diagnosis was performed from the history taken from the patient’s relatives and presenting symptoms. Demographic data, mode and route of poisoning, time from exposure to presentation, clinical symptomatology, grading and routine investigations were evaluated in addition to treatment taken and outcome. Results During the study period, 108 children; mean age was 7.95 ± 4.11 years (range 1. 5-16 years) presented with organophosphorous poisoning. Sixty five (60%) cases were females and 43 (40%) were males. Unintentional acts (87%) were detected more than suicidal (13%) and inhalation route (63.8%) more than ingestion (36. 2%). Miosis was the most frequent clinical sign (100%) followed by respiratory distress (77.7%). Regarding time of presentation to emergency department, 43 (40%) cases were presented within 6 h while others presented more than 6 h post-exposure. Mechanical ventilation (MV) was needed for 14 (13%) cases and 6 (5.5%) cases died due to respiratory failure. Duration of hospital stay, mean time interval from toxic exposure to hospital presentation, leucocytosis, need for MV and cumulative dose of pralidoxime were significantly higher in non survivors than survivors while Pao2 (partial arterial oxygen) and GCS (Glasgow coma scale) were significantly lower. Conclusion This study concluded that time consumed till presentation to hospital, low GCS, need for MV, leucocytosis, decreased PaO2 and increased cumulative dose of pralidoxime were independent risk factors of mortality.

Chemosensory Function

Abstract Alterations in the three chemosensory modalities – smell, taste, and chemesthesis – have been implicated in Coronavirus Disease 2019 (COVID-19), yet emerging data suggest a wide geographic and ethnic variation in the prevalence of these symptoms. Studies on chemosensory disorders in COVID-19 have predominantly focused on Caucasian populations whereas Asians remain understudied. We conducted a nationwide, multicentre cross-sectional study using an online questionnaire on a cohort of RT-PCR-confirmed adult COVID-19 patients in Malaysia between 6 June to 30 November 2020. The aim of our study was to investigate their presenting symptoms and assess their chemosensory function using self-ratings of perceived smell, taste, chemesthesis, and nasal blockage. In this cohort of 498 patients, 41.4% reported smell and/or taste loss when diagnosed with COVID-19, which was the commonest symptom. Blocked nose, loss of appetite, and gastrointestinal disturbances were independent predictors of smell and/or taste loss on multivariate analysis. Self-ratings of chemosensory function revealed a reduction in smell, taste, and chemesthesis across the entire cohort of patients that was more profound among those reporting smell and/or taste loss as their presenting symptom. Perceived nasal obstruction accounted for only a small proportion of changes in smell and taste, but not for chemesthesis, supporting viral disruption of sensorineural mechanisms as the dominant aetiology of chemosensory dysfunction. Our study suggests that chemosensory dysfunction in COVID-19 may be widespread and more common than previously thought among Asians, and manifest as an early symptom of SARS-CoV-2 infection. This has important implications for our understanding of the infectivity of viral strains, diagnosis, and management of this pandemic. Study Registration: NMRR-20-934-54803 and NCT04390165

Breakfast Skipping

Abstract.Aim: To assess the association of breakfast skipping with overweight and obesity among children in Albania, a post-communist country in the Western Balkans, which is undergoing a long and difficult political and socioeconomic transition towards a market-oriented economy. Methods: A nationwide cross-sectional study was carried out in Albania in 2013 including a representative sample of 5810 children aged 7.0 – 9.9 years (49.5% girls aged 8.4 ± 0.6 years and 51.5% boys aged 8.5 ± 0.6 years; overall response rate: 97%). Children were measured for height and weight, and body mass index (BMI) calculated. Cut-off BMI values of the World Health Organization (WHO) and the International Obesity Task Force (IOTF) were used to define overweight and obesity in children. Demographic data were also collected. Results: Upon adjustment for age, sex, and place of residence, breakfast skipping was positively related to obesity (WHO criteria: OR = 1.5, 95% CI = 1.3–1.9; IOTF criteria: OR = 1.9, 95% CI = 1.4–2.5), but not overweight (OR = 1.1, 95% CI = 0.9–1.3 and OR = 1.1, 95% CI = 0.9–1.4, respectively). Furthermore, breakfast skipping was associated with a higher BMI (multivariable-adjusted OR = 1.05, 95% CI = 1.02–1.07). Conclusions: Our findings point to a strong and consistent positive relationship between breakfast skipping and obesity, but not overweight, among children in this transitional southeastern European population. Future studies in Albania and other transitional settings should prospectively examine the causal role of breakfast skipping in the development of overweight and obesity.
