Abstract
Human parechovirus (HPeV) is a common virus that can cause severe infections in newborns. Due to the limited knowledge of the prevalence of HPeV in different cities in China and the unknown association between HPeV infection and clinical characteristics of newborns, this research investigated the epidemiological and clinical characteristics of HPeV infection in hospitalized neonates in Changsha. From August to October 2023, 145 anal swab samples from 96 newborns and 38 pharyngeal swab samples from 33 newborns in the neonatal intensive care unit (NICU) were collected. The prevalence of HPeV was detected by reverse transcription-polymerase chain reaction (RT-PCR). The genomes of HPeV were sequenced and the viral protein 1 (VP1) region was used for genotyping. Phylogenetic analysis and recombination analysis of HPeV genome were performed. Finally, HPeV was detected in 10 out of 44 patients in October, all of them were HPeV-1. The sequenced 4 genomes of HPeV showed high genetic diversity with known strains. Additionally, a HPeV-1 recombinant strain was detected. Compared with HPeV negative patients, HPeV patients had higher prevalence of abdominal pain and diarrhea, intracranial hemorrhage, and purulent meningitis. Compared with HPeV negative patients, HPeV patients had higher peripheral blood lymphocytes, albumin, globulin, pH and lower peripheral blood neutrophils and hemoglobin. HPeV is an important viral cause of newborn infections and appears to be increasing in prevalence in recent years. Characteristic clinical pictures exist in HPeV infections, and further research is needed to accumulate more cases to obtain a comprehensive understanding of HPeV infections.

INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2023; 111:105435. [PMID: 37059255 DOI: 10.1016/j.meegid.2023.105435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 04/08/2023] [Accepted: 04/11/2023] [Indexed: 04/16/2023]
Abstract
We analyzed the prevalence and genotypes of Parechovirus A (PeV-A) in children with diarrhea in Beijing, China, 2017-2019. A total of 1734 stool samples collected from children <5 years of age with diarrhea were tested for the presence of PeV-A. Viral RNA was detected by real-time RT-PCR, and then genotyped by nested RT-PCR. We detected PeV-A in 93 (5.4%, 93/1734) samples, of which 87 could be genotyped by amplification of either the complete or partial VP1 region or the VP3/VP1 junction region. The median age of PeV-A infected children was 10 months. Most PeV-A infections were observed between August and November, with a peak in September. Seven known genotypes of PeV-A1A, -A1B, -A3, -A4, -A6, -A8 and -A11 were detected and PeV-A1B was the most prevalent genotype. Coinfection with other diarrheal viruses was observed in 30.1% (28/93) of PeV-A positive samples. All strains of PeV-A1A, -A1B, -A4 and -A6 obtained in this study contained the arginine-glycine-aspartic (RGD) motif, while all strains of PeV-A3, -A8 and -A11 lacked it. This study revealed a high genetic diversity of PeV-A circulating in Beijing and PeV-A11 was reported for the first time in children with diarrhea in China.

Abstract
Parechovirus A (PeV-A) belongs to the genus Parechovirus in the family Picornaviridae associated with gastroenteritis illness, particularly in children, but prior studies have produced ambiguous results. This study aimed to provide a systematic review of the PeV-A prevalence in paediatric patients with gastroenteritis and the association between PeV-A infection and the risk of gastroenteritis. A systematic search of the literature was conducted in Embase, PubMed, Scopus, and Web of Science, in combination with the reference lists of potentially relevant articles. A random effect-based model was applied to analyse data from included studies. The pooled odds ratio (OR) and 95% confidence interval (CI) were used for assessing the risk between PeV-A and gastroenteritis. A total of 41 studies assessing 21,850 cases and 1746 healthy controls were analysed. The overall prevalence of PeV-A among paediatric patients with gastroenteritis was 10.4% (95% CI: 7.9%-13.2%), while it was estimated at 8.1% (95% CI: 5.1%-11.7%) based on studies only investigating children without gastroenteritis. The pooled OR for all eight case-control studies was 1.079 (95% CI: 0.730-1.597), indicating there was no statistically significant association. PeV-A genotype 1 was the most frequent genotype of PeV-A infection in children with gastroenteritis. The PeV-A prevalence in cases of gastroenteritis is higher than that in children without gastroenteritis. However, the present meta-analysis did not indicate a statistically significant association between PeV-A infection and risk of gastroenteritis. Given the considerable heterogeneity and various sample sizes among the included studies, relevant investigations in the future should be carried out based on a large-scale population.

Abstract
Parechoviruses are emerging pathogens of humans often affecting the pediatric age group, with a growing line of evidence implicating them as agents of a broad spectrum of clinical syndromes in adults. However, because many clinicians are not familiar with the manifestation of the infections, they are not included in the list of diagnostic pathogens. Furthermore, due to the indistinguishable feature of the infection compared with other common pathogens, a large number of cases are likely to go unchecked. Some may develop asymptomatic infection and recover without overt clinical disease. In this manuscript, we reviewed available literature on parechovirus infection in adult and summarized information relating to epidemiology, clinical manifestation, laboratory diagnosis, and therapeutics. The information provided should help in early case detection and support an evidence-based clinical decision.

Abstract
Aim: Human parechovirus (HPeV) is one of the major causes of acute gastroenteritis in children. Materials & methods: Stool specimens (n = 250) were collected from children aged ≤3 years during 2018–2019. HPeV RNA was detected by reverse transcription-PCR and genotyping by VP1 gene, Rotavirus (RV) screened by ELISA. Results: HPeV was detected in 12% of the cases. The children under 6-months old (64.2%) were a sensitive group and HPeV was more prevalent during January–February (73.3%). The co-infection of HPeV with RV was 50%. All of the sequenced samples belong to the HPeV-1 genotype. Conclusion: HPeV-1 is one of the major causes of acute viral gastroenteritis in children and the co-infection of RV can be an additional infection in some cases.

Abstract
Parechovirus A (PeV-A), which causes a wide variety of diseases, is prevalent among young children. However, little is currently known about PeV-A infections in children with acute gastroenteritis in mainland China. In this study, we investigated the molecular epidemiology of acute gastroenteritis in Shenzhen, southern China, with an emphasis on PeV-A infections. A total of 1220 stool specimens from 1220 outpatient children under 5 years old with acute gastroenteritis were collected from January 2016 to December 2018. Viral RNA was detected by a real-time RT-PCR and PCR method. The PeV-A isolates were genotyped by sequencing the VP3/VP1 region. Of 1220 specimens, 148 (12.1%) were positive for PeV-A. The predominant genotype was PeV-A 1B (68.9%), followed by PeV-A 4 (12.2%), PeV-A 14 (6.1%), PeV-A 1A (5.4%), PeV-A 6 (2.7%), PeV-A 3 (2.7%) and PeV-A 5 (2.0%). It was found that 68.2% of PeV-A infections occurred in the summer and rainy months (June to September) in southern China. The majority of PeV-A-positive patients (97.3%) were younger than 24 months old. PeV-A coinfection with norovirus, rotavirus, astrovirus and adenovirus was found in thirty specimens (30/148, 20.3%), five specimens (5/148, 3.4%), five specimens (5/148, 3.4%), and two specimens (2/148, 1.4%), respectively. Coinfections with more than one other enteric virus were not observed in any of the PeV-A-positive specimens. Phylogenetic analysis revealed that the PeV-A isolates from Shenzhen were closely related to each other and to strains circulating in China, suggesting endemic circulation of PeV-A in China. The results of this study indicate that PeV-A is one of important pathogens of acute gastroenteritis in young children and that coinfection is a possible mode of PeV-A infection. PeV-A associated with acute gastroenteritis exhibited high genotypic diversity in Shenzhen, southern China.
