Objective:To understand the prevalence of human parechovirus (HPeV) in neonates of Hunan Provincial People’s Hospital, and analyze genetic evolutionary characteristics.Methods:From June to September 2021, fecal samples of inpatient neonates were collected in Hunan Provincial People′s Hospital. TaqMan real-time qPCR and RT-PCR were used for HPeV screening and genotyping. High-throughput sequencing and PCR were used to obtain whole genomes. Phylogenetic analysis was performed after sequencing.Results:A total of 123 fecal samples of neonates were collected, of which 22 were HPeV positive, with 17.89% positive rate. All the strains belonged to the HPeV-1 genotype. One full-length genomic sequence of 7 269 bp were obtained, and provisionally named Hunan/HPeV/2021, which has the highest nucleotide identity with known HPeV-1 genotype, with 86.6%-91.9% nucleotide identity. The nucleotide and amino acid identity of open reading frame (ORF) with known similar sequences were 90.3%-92.6% and 97.3%-98.3%, respectively. The phylogenetic analysis showed that Hunan/HPeV/2021 belongs to the HPeV-1 genotype, which is clustered into the same clade as the popular HPeV-1 strains in China.Conclusions:HPeV has a high prevalence in inpatient neonates of Hunan Provincial People’s Hospital and belong to the HPeV-1 genotype.

Objective:To study the clinical characteristics of children with adenovirus pneumonia complicated with liver injury and the understanding of clinicians.Methods:The children diagnosed with community-acquired adenovirus pneumonia were enrolled from January 1, 2013 to December 31, 2020. The clinical characteristics of the normal liver function group and the liver injured group were compared, and multivariate regression was applied.Results:Among the 3 294 enrolled children, 1 704 children had elevated alanine aminotransferase and/or aspartate aminotransferase on admission, and the liver function impairment rate was 51.7% (1 704/3 294), of which 1 671 cases were mildly injured (98.06%, 1 671/1 704), 28 cases were moderately injured (1.64%, 28/1 704), and 5 cases were severely injured (0.29%, 5/1 704). Compared with the normal liver function group, the proportion of male children in the liver injured group was higher (68.1% vs. 64.2%, P=0.017), and the age was younger[16(9, 30) months vs. 38(19, 53) months, P<0.001]. Children with liver injury were more likely to have wheezing (32.9% vs. 18.7%, P<0.001), shortness of breath (13.7% vs. 9.1%, P<0.001), and diarrhea (11.0% vs. 4.7%, P<0.001). The white blood cell counts, neutrophil counts and hemoglobin in the liver injured group were lower than those in the normal group, while the lymphocyte counts were higher than those in the normal group. The levels of creatine kinase, cardiac creatine kinase and lactate dehydrogenase were higher. The proportion of severe pneumonia in the liver injured group (26.9% vs. 11.2%, P<0.001) was higher than that in the normal liver function group, and the case fatality rate was significantly higher (1.47% vs. 0.25%, P<0.001). Comparing the probability of liver injury in children with mild and severe adenovirus pneumonia, it was found that the severe pneumonia group had more frequent liver injury (73.0% vs 46.6%, P<0.001), and both moderate and severe liver injury groups were higher than in the mild group. Further multivariate logistic regression analysis did not find a significant factor associated with the incidence of liver injury. Conclusions:The incidence of adenovirus pneumonia in children with liver injury was high, and mild injury is more common. Children with liver injury were younger, had more severe clinical symptoms such as wheezing and shortness of breath, and higher proportion of severe pneumonia and mortality. Among them, children with severe pneumonia had a higher proportion of liver injury, and moderate to severe injury was more common. The monitoring of children with different degrees of liver injury should be strengthened.

This paper reports 3 cases of acute hepatitis of unknown cause in children who met the case definition of WHO. Human adenovirus group C was detected in case 3, and the quantity of viral DNA was relatively high, which may be related to the liver function damage in the patient, but its role in pathogenesis needs further study to confirm.

Results: (1) A total of 33 056 children with CAP were included in this study.A total of 3 770 children with HAdV positive were detected, with a total detection rate of 11.40% (3 770/33 056). From May 2014 to April 2019, the detection rates of adenovirus in different years were 13.76%, 8.57%, 7.94%, 9.53%, 12.36% and 24.75% respectively.Adenovirus detection rate reached its peak in 2019.(2) The detection rate of HAdV among male children were higher than that among female children (χ²= 6.374, P=0.012). Among 3 770 children with HAdV infection, 3 036 (80.53%) were from 6 months to 5 years old.The detection rate of adenovirus were different in different age groups.The highest detection rate was 16.65% in 3 to 5 years old group (χ²=526.494, P<0.001). Among children with severe pneumonia, the detection rate of adenovirus was 18.43% (415/2 252). The detection rate of adenovirus was the highest in the age group of 6 months to 1 years, and the difference was statistically significant(χ²=71.485, P<0.001). (3) The detection rate of adenovirus was the lowest in autumn, and the other three seasons were all high- incidence seasons (χ²= 268.744, P<0.001). (4) The hospitalization days of adenovirus pneumonia were longer than those of non-adenovirus pneumonia (Z=-10.419, P<0.001). Conclusion The prevalence of HAdV infection is related to age, season and sex.The susceptibility of adenovirus varies with severity of pneumonia.We should be vigilant against the outbreak of adenovirus infection characterized by years.
