Relationship between asymptomatic rotavirus infection and jaundice in neonates: a retrospective study.

ABSTRACT: BACKGROUND:Rotavirus (RV) infection in neonates can be mild or even asymptomatic. In RV infection, jaundice is often reported, but the relationship between jaundice and RV infection has not been studied. This study aimed to determine the importance of asymptomatic RV screening in neonates with jaundice. METHODS:Neonates from the neonatal intensive care unit (NICU) of Chonbuk National University Hospital, those transferred from local obstetrics and gynecology hospitals and outpatient clinics were selected from 2014 to 2017. The study included only infants aged between 3 and 28?days. Jaundice was defined according to gestational age and birth age, in accordance with the American Academy of Pediatrics guidelines criteria. RV infection was confirmed by a stool test, and RV screening and laboratory tests were performed at admission. RESULTS:Among 596 patients, 166 patients had jaundice. RV infection was observed in 70 (42%) jaundice patients. There were 36 (22%) jaundice patients with asymptomatic RV infection. Patients with onset of jaundice 3-7?days after birth had a high incidence of RV infection. When the RV test was positive, the risk of jaundice was significantly high [odds ratio (OR) 1.89; 95% confidence interval (CI), 1.20-2.98; p?=?0.006]. CONCLUSIONS:Infants with the onset of jaundice >?3?days after birth were likely to have RV infection. Therefore, we suggest that screening tests for RV infection be included as part of the evaluation of jaundiced infants presenting to NICU.

Project description:Background and objectiveNeonatal jaundice is a common clinical disease in neonates. Pathologic jaundice is more harmful to neonates. There are a few studies on the biomarkers of pathologic jaundice and the correlation between gut microbiota and clinical indices. Therefore, we aimed to reveal the characteristics of gut microbiota in pathologic jaundice, provide potential biomarkers for the diagnosis of pathologic jaundice, and find the correlation between gut microbiota and clinical indices.MethodsFourteen neonates with physiologic jaundice were recruited into a control group (Group A). Additionally, 14 neonates with pathologic jaundice were recruited into a case group (Group B). The microbial communities were analyzed using 16S rDNA sequencing. LEfSe and the differences in the relative abundance of gut microbiota were used to identify different bacteria among the two groups. The ROC curve was used to assess effective biomarkers for pathologic jaundice. Spearman's rank-sum correlation coefficient was used to evaluate the correlation between gut microbiota and clinical indices.ResultsThere were no differences in the total richness or diversity of gut microbiota between the two groups. At the phylum and genus levels, compared with the control group, Bacteroidetes (p = 0.002) and Braydrhizobium (p = 0.01) were significantly higher, while Actinobacteria (p = 0.003) and Bidfldobacterium (p = 0.016) were significantly lower in the case group. Bacteroidetes were valuable in differentiating pathologic jaundice from physiologic jaundice by the ROC curve, and the area under the ROC curve (AUC) value was 0.839 [95%CI (0.648-0.995)]. In the case group, Bacteroidetes were negatively associated with total bilirubin (TBIL) (p < 0.05). In the control group, Bacteroidetes were positively associated with TBIL (p < 0.05).ConclusionBacteroidetes could be used as biomarkers to identify pathologic jaundice and Bacteroidetes are positively associated with bilirubin levels.

Project description:BackgroundCaffeine is a routinely prescribed pharmacological active compound in neonatal intensive care units (NICU) for treating apnea of prematurity (AOP), which also decreases the risk of bronchopulmonary dysplasia and cerebral palsy in neonates. Caffeine-induced excessive calcium loss can promote the development of metabolic bone disease (MBD) in preterm neonates. This study aimed to evaluate the effect of the caffeine regimen on the development of osteopenia of prematurity (OOP), using serum alkaline phosphatase (serum-ALP) concentrations as a surrogate marker at the 4th week of life.MethodsThis retrospective cohort study was conducted including neonates of < 32 weeks gestational age (GA) and birth weight < 1500 g, admitted to NICU from April-2017 to December-2018 and received caffeine therapy till 28 days of life for AOP. Based on serum-ALP levels, formed the high and low-ALP groups. Neonatal characteristics, caffeine regimen, risk factors for OOP, including duration of parenteral nutrition (PN), exposure to medicines associated with MBD, and intake of essential vitamins and minerals, were compared in both groups. Predictors of OOP were analyzed through logistic regression.ResultsFrom the total of 268 participants, 52 (19%) developed OOP, mostly female (61.5%). In the high ALP group, the serum-ALP levels were significantly higher than in the low-ALP group (725.0 ± 143.8 vs 273.6 ± 55.0 units/L, p < 0.001). The high-ALP group received significantly (p < 0.001) higher daily and cumulative caffeine doses and were associated with a higher likelihood of developing OOP in this study cohort [cumulative dose (mg) (AOR = 1.082 95% CI 1.011 to 1.157) and daily dose (mg/kg/day) (AOR = 2.892 95% CI 1.392 to 6.007)]. Smaller GA was found directly related to OOP. Among the other medical risk factors, phosphorus intake was significantly low in the high-ALP group. No, significant relationship between duration of PN and use of steroids and diuretics, and intake of vitamins and minerals were identified.ConclusionThe daily and cumulative doses of caffeine and smaller GA are associated with the development of OOP in this study cohort. Clinical randomized control studies are needed to validate the outcomes and determine the range of safest and most effective caffeine doses for treating AOP in preterm neonates.

Project description:BackgroundFew studies have used real-world data to evaluate the impact of antidepressant use on the risk of developing severe outcomes after SARS-CoV-2 Omicron infection.MethodsThis is a retrospective cohort study using propensity-score matching to examine the relationship between antidepressant use and COVID-19 severity. Inpatient and medication records of all adult COVID-19 patients in Hong Kong during the Omicron-predominated period were obtained. Severe clinical outcomes including intensive care unit admission and inpatient death after the first positive results of reverse transcription polymerase chain reaction as well as a composite outcome of both were studied. Cox proportional hazard models were applied to estimate the crude and adjusted hazard ratios (HR).FindingsOf 60,903 hospitalised COVID-19 patients admitted, 40,459 were included for matching, among which 3821 (9.4%) were prescribed antidepressants. The rates of intensive care unit admission, inpatient death, and the composite event were 3.9%, 25.5%, and 28.3% respectively in the unexposed group, 1.3%, 20.0%, and 21.1% respectively in the exposed group, with adjusted HR equal to 0.332 (95% CI, 0.245-0.449), 0.868 (95% CI, 0.800-0.942), and 0.786 (95% CI, 0.727-0.850) respectively. The result was generally consistent when stratified by selective serotonin reuptake inhibitors (SSRIs) and non-SSRIs. Antidepressants with functional inhibition of acid sphingomyelinase activity, specifically fluoxetine, were also negatively associated with the outcomes. The effect of antidepressants was more apparent in female and fully vaccinated COVID-19 patients.InterpretationAntidepressant use was associated with a lower risk of severe COVID-19. The findings support the continuation of antidepressants in patients with COVID-19, and provide evidence for the treatment potential of antidepressants for severe COVID-19.FundingThis research was supported by Health and Medical Research Fund [grant numbers COVID190105, COVID19F03, INF-CUHK-1], Collaborative Research Fund of University Grants Committee [grant numbers C4139-20G], National Natural Science Foundation of China (NSFC) [71974165], and Group Research Scheme from The Chinese University of Hong Kong.

Project description:BackgroundGroup A rotaviruses are the major causative agents of pediatric gastroenteritis worldwide. Several studies have reported the predominance of G4P[6] rotavirus genotypes in Korean neonates, which is uncommon in other countries. Therefore, the purposes of this study were to determine the genotype constellations of complete genomes of G4P[6] rotavirus strains isolated from Korean neonates using next-generation sequencing, to compare these sequences with other G4P[6] strains in other countries, and to determine the reason for the predominance of G4P[6] genotypes in Korean neonates.ResultsTwenty rotavirus G4P[6] strains, isolated from January 2013 to January 2016, were selected for whole-genome sequencing. Eleven rotavirus genes were amplified using specific primer sets, and sequencing was carried out using an Ion S5 XL next-generation sequencing platform. Genotypes of each gene were determined, and phylogenetic analyses were performed to investigate genetic distances between genes of rotaviruses in this study and those of other rotavirus G4P[6] strains whose whole-genome sequences were previously published. All 20 rotavirus strains in this study had the same genotype: G4-P[6]-I1-R1-C1-M1-A1-N1-T1-E1-H1, representing the Wa-like genotype constellation. BLAST searches of 20 G4P[6] rotavirus strains revealed that all G4 sequences in this study showed the highest nucleotide identity to G4 sequences of G4P[6] rotavirus strains isolated in Korea in 2008 (GenBank accession number: FJ603447). Additionally, P[6] gene sequences in this study showed the highest nucleotide identity to P[6] sequences of G4P[6] strains detected in Korea in 2002 (AY158093). Phylogenetic and nucleotide sequence analyses showed that G4P[6] strains in this study and previously reported G4P[6] strains in Korea were mostly detected in neonates and had similar G4 and P[6] sequences compared with other G4P[6] strains detected in other countries.ConclusionsThis study showed that the whole-genome constellation of rotavirus G4P[6] strains from Korean neonates resembled a Wa-like genotype constellation. Additionally, rotavirus genotypes detected in Korean neonates had unique P[6] sequences, which may be the cause of Korean neonatal rotavirus infection.
