Abstract

Objectives: To report epidemiological features, clinical characteristics, and outcomes of human rhinovirus (HRV) infections in comparison with other community acquired respiratory virus (CRV) infections in patients hospitalized for two consecutive years., Methods: This was a cross-sectional study. Clinical, epidemiological, and laboratory data of patients hospitalized with acute respiratory syndrome in a tertiary care hospital from 2012 to 2013 were reviewed., Results: HRV was the most common CRV observed (36%, 162/444) and was present in the majority of viral co-detections (69%, 88/128), mainly in association with human enterovirus (45%). Most HRV-infected patients were younger than 2 years (57%). Overall, patients infected with HRV had a lower frequency of severe acute respiratory infection than those infected with other CRVs (60% and 84%, respectively, p=0.006), but had more comorbidities (40% and 27%, respectively; p=0.043). However, in the adjusted analysis this association was not significant. The mortality rate within the HRV group was 3%. Detection of HRV was more prevalent during autumn and winter, with a moderately negative correlation between viral infection frequency and temperature (r=-0.636, p<0.001) but no correlation with rainfall (r=-0.036, p=0.866)., Conclusion: HRV is usually detected in hospitalized children with respiratory infections and is often present in viral co-detections. Comorbidities are closely associated with HRV infections. These infections show seasonal variation, with predominance during colder seasons., (Copyright © 2016. Published by Elsevier Editora Ltda.)

Os rinovírus têm sido descritos como agente etiológico de mais de 50% das infecções do trato respiratório ao redor do mundo. O objetivo deste trabalho foi avaliar a ocorrência de rinovírus humano (HRV), influenza vírus A e B, vírus respiratório sincicial humano e metapneumovírus (hMPV) em uma população de idosos que apresentava sintomas de gripe ou resfriado, e que residiam na Cidade de Botucatu, Estado de São Paulo, Brasil. Métodos: Foram coletados swabs nasais de 47 idosos após visitas de inclusão, entre os anos de 2002 e 2003 e que foram testadas através de GeneScan RT-PCR. Resultados: HRV foi detectado em 28.6% (14/47) e hMPV em 2% (1/47). De 14 amostras positivas para HRV, 9 foram sequenciadas, mostrando a seguinte distribuição de grupos: grupo A: 6 amostras, grupo B: 1 amostra e grupo C: 2 amostras. Conclusões: A alta incidência de HRV durante os meses de ocorrência de gripe necessita de estudos posteriores para avaliar o impacto desse vírus entre os idosos. A alta frequência de HRV pode contribuir para o aumento da demanda por serviços de saúde durante a estação de influenza. Introduction: Acute respiratory tract infections are the most common illness in all individuals. Rhinoviruses have been reported as the etiology of more than 50% of respiratory tract infections worldwide. The study prospectively evaluated 47 elderly individuals from a group of 384 randomly assigned for acute respiratory viral infections (cold or flu) and assessed the occurrence of human rhinovirus (HRV), influenza A and B, respiratory syncytial virus and metapneumovirus (hMPV) in Botucatu, State of São Paulo, Brazil. Methods: Forty-nine nasal swabs collected from 47 elderly individuals following inclusion visits from 2002 to 2003 were tested by GenScan RT-PCR. HRV-positive samples were sequenced for phylogenetic analysis. Results: No sample was positive for influenza A/B or RSV. HRV was detected in 28.6% (14/47) and hMPV in 2% (1/47). of 14 positive samples, 9 isolates were successfully sequenced, showing the follow group distribution: 6 group A, 1 group B and 2 group C HRVs. Conclusions: The high incidence of HRV during the months of the influenza season requires further study regarding HRV infection impact on respiratory complications among this population. Infection caused by HRV is very frequent and may contribute to increasing the already high demand for healthcare during the influenza season.
