High rate of human bocavirus and adenovirus coinfection in hospitalized Israeli children.

ABSTRACT: We investigated coinfection of human bocavirus (HBoV) and other respiratory viruses in hospitalized children by real-time PCR. A high rate (69.2%) of adenovirus infection was found among children infected with HBoV. Such high rates of HboV-adenovirus coinfection have not been previously reported, underscoring the need to investigate the contribution of HBoV in patient clinical presentations.

Human bocavirus infections in hospitalized Greek children.

Project description:INTRODUCTION:The epidemiology of human bocavirus (HBoV) infections has not been described in Greece, a south-eastern European country. To define the epidemiological profile and the clinical characteristics associated with HBoV infection in a population of children hospitalized with respiratory tract infection. MATERIAL AND METHODS:During a one-year period throat swab samples were collected from 370 previously healthy children, aged 14 days to 13 years, admitted to two different paediatric wards because of respiratory tract infection. Samples were tested for HBoV by PCR amplifying a part of the NS1 gene. RESULTS:Human bocavirus was detected in 12 children (3.2%). Four of the 12 cases were co-infections, 3 of them with influenza A and 1 with coronavirus OC43. Cases were observed only during the cold months. The mean age of children was 1.8 years (range 2 months to 4 years). The most common symptoms were fever, cough and various degrees of respiratory distress. All children were clinically diagnosed as having lower respiratory tract infections, mainly pneumonia and acute laryngotracheobronchitis, and recovered uneventfully. CONCLUSIONS:HBoV infections occur in Greece mostly among very young children. They accounted for 3.2% of children hospitalized with acute respiratory disease. Cases were observed only in late autumn to early spring.

Human bocavirus infections in hospitalized children and adults.

Project description:Studies have reported human bocavirus (HBoV) in children with respiratory tract infections (RTIs), but only occasionally in adults. We searched for HBoV DNA in nasopharyngeal aspirates (NPAs) from adults with exacerbations of chronic bronchitis or pneumonia, from children hospitalized for acute RTIs, and from asymptomatic children during the winter of 2002-2003 in Canada. HBoV was detected in NPAs of 1 (0.8%) of 126 symptomatic adults, 31 (13.8%) of 225 symptomatic children, and 43 (43%) of 100 asymptomatic children undergoing elective surgery. Another virus was detected in 22 (71%) of the 31 HBoV-positive NPAs from symptomatic children. Two clades of HBoV were identified. The pathogenic role of HBoV in RTIs is uncertain because it was frequently detected in symptomatic and asymptomatic children and was commonly found with other viruses in symptomatic children.

Detection of human bocavirus in children hospitalized because of acute gastroenteritis.

Project description:The idea that human bocavirus (hBoV) infection possibly plays a role in gastroenteritis has been suggested because of the frequent manifestation of gastrointestinal symptoms. The purpose of this study was to investigate the prevalence of hBoV in children with gastroenteritis. We studied the etiologic agents in 962 children hospitalized with gastroenteritis. Viral etiologic agents were detected by enzyme-linked immunosorbent assay or reverse-transcriptase polymerase chain reaction. A viral agent was found in 44.4% of the study population: rotavirus, norovirus, adenovirus, and astrovirus were detected in 25.7%, 13.7%, 3.0%, and 1.1% of the study population, respectively; hBoV was detected in 0.8%, which suggests that it might play a minor role in gastroenteritis.

Human Bocavirus quantitative DNA detection in French children hospitalized for acute bronchiolitis.

Project description:BACKGROUND:Human Bocavirus (HBoV) is a newly discovered parvovirus whose role as a causative agent of respiratory disease remains unclear. STUDY DESIGN:We investigated the presence of HBoV by quantitative PCR in the nasopharyngeal samples of 192 French children consecutively hospitalized for acute bronchiolitis. Other common respiratory viruses were detected using immunofluorescence assays, cell culture detection, or RT-PCR assays. RESULTS:HBoV was detected in 24 (12.5%) of 192 study children. In 14/192 cases (7%) HBoV was the sole isolate and in 10/192 (5%) it was part of a mixed viral infection. HBoV was the third most common pathogen detected after respiratory syncytial virus (45/192; 23%) and rhinovirus (24/192; 12%). It occurred more often in infants aged 1-12 months (P=0.002). Median levels of HBoV DNA genome in respiratory samples were significantly higher in patients with single HBoV infection than in patients with mixed respiratory viral infection with HBoV (4x10(8)copies/ml vs. 2x10(3)copies/ml, P<0.001). CONCLUSIONS:Our data suggest that HBoV at a high viral load could be an etiologic agent of respiratory tract disease, whereas the exact role of HBoV at a low viral load, as etiological cause or as pathophysiological co-factor of respiratory diseases, remains to be determined.

Human bocavirus in children hospitalized for acute gastroenteritis: a case-control study.

Project description:BackgroundHuman bocavirus (HBoV) was recently discovered in children with respiratory tract disease and gastroenteritis. The causative role of HBoV in human gastroenteritis remains uncertain, and, to our knowledge, no previous case-control study has studied the relationship between HBoV and gastroenteritis.MethodsWe conducted a case-control study that examined stool samples from 397 children with diarrhea and from 115 asymptomatic control subjects. HBoV was detected using polymerase chain reaction. Real-time polymerase chain reaction was used to quantify the HBoV loads in case and control groups. Common enteric viruses were examined using enzyme-linked immunosorbent assays, polymerase chain reaction, and reverse-transcription polymerase chain reaction.ResultsAt least 1 viral agent was discovered in 60.2% of cases. HBoV was detected in 14 samples, and 9 were coinfected with either rotavirus (7 of 14 samples) or human calicivirus (2 of 14). Many (8 [57.1%] of 14) of the HBoV infections occurred during September-December 2006. Most (12 [85.7%]) of the HBoV-infected children were 7-18 months of age. The percentage of children with HBoV infection did not differ significantly between case patients and control subjects (3.5% vs. 3.5%), and the statistical analysis did not support a correlation between HBoV infection and more-severe clinical symptoms. The viral load differences between the 2 groups were not statistically significant (P = .09, by log-normal Student's t test). In addition, the VP1/VP2 partial gene of HBoV from case patients and control subjects showed minimal sequence variation.ConclusionsA single genetic lineage of HBoV was revealed in persons in China. Despite its high prevalence in stool samples, our study does not support a causative role of HBoV in gastroenteritis.

The Burden of Human Bocavirus 1 in Hospitalized Children With Respiratory Tract Infections.

Project description:BackgroundHuman bocavirus 1 (HBoV1) is frequently codetected with other viruses, and detected in asymptomatic children. Thus, the burden of HBoV1 respiratory tract infections (RTI) has been unknown. Using HBoV1-mRNA to indicate true HBoV1 RTI, we assessed the burden of HBoV1 in hospitalized children and the impact of viral codetections, compared with respiratory syncytial virus (RSV).MethodsOver 11 years, we enrolled 4879 children <16 years old admitted with RTI. Nasopharyngeal aspirates were analyzed with polymerase chain reaction for HBoV1-DNA, HBoV1-mRNA, and 19 other pathogens.ResultsHBoV1-mRNA was detected in 2.7% (130/4850) samples, modestly peaking in autumn and winter. Forty-three percent with HBoV1 mRNA were 12-17 months old, and only 5% were <6 months old. A total of 73.8% had viral codetections. It was more likely to detect HBoV1-mRNA if HBoV1-DNA was detected alone (odds ratio [OR]: 3.9, 95% confidence interval [CI]: 1.7-8.9) or with 1 viral codetection (OR: 1.9, 95% CI: 1.1-3.3), compared to ≥2 codetections. Codetection of severe viruses like RSV had lower odds for HBoV1-mRNA (OR: 0.34, 95% CI: 0.19-0.61). The yearly lower RTI hospitalization rate per 1000 children <5 years was 0.7 for HBoV1-mRNA and 8.7 for RSV.ConclusionsTrue HBoV1 RTI is most likely when HBoV1-DNA is detected alone, or with 1 codetected virus. Hospitalization due to HBoV1 LRTI is 10-12 times less common than RSV.

High incidence of human bocavirus infection in children in Spain.

Project description:BACKGROUND:The newly identified human bocavirus (HBoV), a member of the Parvoviridae family, has been associated to low respiratory tract infections in young children. OBJECTIVES:To present the epidemiological profile and the main clinical characteristics showed by children infected with this virus in Spain. STUDY DESIGN:We have studied the incidence of HBoV and other 15 respiratory viruses in 917 nasopharyngeal aspirates taken from 730 infants and children under age of 14 with acute lower respiratory tract infection from September-04 to August-06. RESULTS:HBoV was detected in 123 samples (13.4%) showing a seasonal distribution with November and December as the peak months. Out of the 558 samples which rendered a positive result for at least one of the virus tested, HBoV (22%) ranked fourth behind respiratory syncytial virus (181, 32%), adenoviruses (155, 28%) and rhinoviruses (136, 24%). Co-infections with HBoV and other respiratory viruses were detected in 74 out of 123 HBoV-positive specimens (60%). In addition, HBoV was also found in stool and, for the first time, in urine samples. CONCLUSIONS:Results obtained provide further evidence that HBoV is involved in acute lower respiratory tract infections. HBoV-associated disease should not be limited to the respiratory tract.
