3.New Tread of Association of Rhinovirus and Asthma.
Pediatric Allergy and Respiratory Disease 2008;18(3):202-207
Exacerbations of asthma is major causes of morbidity, mortality, and health-care costs. Over the decade, studies using new molecular diagnostic techniques have established that respiratory viruses are a major cause of exacerbations of asthma. The most prevalent viruses detected during exacerbations are the rhinovirus. Despite the burden of disease associated with exacerbations, little is known about the mechanisms of virus-induced exacerbations of airway diseases. Exacerbations are associated with increased airway inflammation in patients with asthma, but many questions remain unanswered regarding the key inflammatory cells and mediators involved. Identifying the key inflammatory mediators involved in exacerbations holds the promise of developing diagnostic and prognostic markers of exacerbation. The purpose of this review is to summarize the recent change in our understanding of the clinical manifestations of rhinovirus infection than occurred as a result of the improved diagnostic sensitivity provided by the multiplex-polymerase chain reaction (PCR) assays and serotypes.

Despite asthma being the most common chronic childhood ailment, there is still much to learn about the disease. Early childhood infections with well-known or emerging viruses can lay the pathophysiologic framework for asthma development and exacerbation later in life, which may be due partly to alteration of the airway microbiome. Once asthma is established, acute exacerbations are usually associated with infections with respiratory viruses, such as rhinoviruses (RVs). Once again, there are bidirectional interactions between viruses and airway bacteria that appear to influence the severity of illness and the likelihood of exacerbation. Studies employing recent advances in viral and bacterial identification analytic techniques will clarify these new concepts and may provide the basis for new treatments or prevention or respiratory infection-associated exacerbation. This paper is a review of the associations among respiratory viruses, bacteria, inflammatory mechanisms, and asthma exacerbation.

5.Updates in the Relationship Between Human Rhinovirus and Asthma.
Allergy, Asthma & Immunology Research 2012;4(3):116-121
Human rhinovirus (HRV) is a nonenveloped, single stranded RNA virus belonging to the family Picornaviridae. HRV infections can cause both upper and lower respiratory illnesses in children and adults. Lower respiratory illnesses are more likely to occur in specific high risk groups, including infants, and children and adults with asthma. The relationships between rates of infection and the risk of clinical illness and exacerbation are not completely understood. Recent studies employing polymerase chain reaction and other molecular techniques indicate that there are new branches on the HRV family tree, and one characteristic of recently detected viruses is that they cannot be detected by standard tissue culture. Here we review the current literature and discuss new advances in understanding the link between HRV and asthma.

BACKGROUND: There have been no previous studies on the effect of anesthetic agents on rhinovirus (RV) infection, which is the most common pathogen of the common cold in human airway epithelial cells. We investigated the effects of propofol and etomidate on the airway epithelial cells infected with RV. METHODS: RV-infected A549 cells were treated with propofol and etomidate for 24 hours. On the third day of infection, cells and supernatant were collected to measure the intercellular adhesion molecule-1 (ICAM-1) expression, viral titer and the amount of cytokine. The extents of the viral replication were expressed as viral titers by 50% tissue culture infection dose (TCID50). RESULTS: The ICAM-1 expression of the groups treated with propofol 1, 10, 100micrometer vs etomidate 1, 5, 25micrometer were 15.6 +/- 4.2, 16.4 +/- 3.7, 14.1 +/- 4.7% vs 16.8 +/- 5.7, 16.4 +/- 5.3, 17.2 +/- 4.5%, but there were not significantly different among subgroups. Productions of cytokines were increased after RV-infection, but there were not significantly different among the propofol and etomidate treated subgroups. The viral titers of the groups treated with propofol and etomidate were not significantly different among subgroups either. CONCLUSIONS: Propofol and etomidate had no effect on the replication of RV and the cytokine release after RV infection in human airway epithelial cells.

PURPOSE: This study aimed to investigate the association between respiratory virus infection and pneumococcal colonization in children. METHODS: From May 2009 to June 2010, nasopharyngeal (NP) aspirates were obtained from patients under 18 years old who visited Seoul National University Children's Hospital for respiratory symptoms. NP samples were used to detect respiratory viruses (influenza virus A and B, parainfluenza virus 1, 2 and 3, respiratory syncytial virus A and B, adenovirus, rhinovirus A/B, human metapneumovirus, human coronavirus 229E/NL63 and OC43/HKU1) by RT-PCR and pneumococcus by culture. RESULTS: Median age of the patients was 27 months old. A total of 1,367 NP aspirates were tested for respiratory viruses and pneumococcus. Pneumococcus was isolated from 228 (16.7%) of samples and respiratory viruses were detected from 731 (53.5%). Common viruses were rhinovirus (18.4%), respiratory syncytial virus (RSV) A (10.6%), adenovirus (6.9%), influenza virus A (6.8%). Pneumococcal isolation rate was significantly higher in the cases of positive virus detection than negative detection [21.3% (156/731) vs. 11.3% (72/636), P<0.001]. For individual viruses, pneumococcal isolation rate was positively associated with detection of influenza virus A [24.7% (23/93) vs 16.1% (205/1274), P=0.001], RSV A [28.3% (41/145) vs 15.3% (187/1222), P=0.001], RSV B [31.3% (10/32) vs 16.3% (218/1335), P=0.042], rhinovirus A/B [22.6% (57/252) vs 15.3% (171/1115), P=0.010]. CONCLUSION: The study revealed that pneumococcal isolation from NP aspirates is related with respiratory virus detection. The result of this study could be used to investigate how respiratory viruses and pneumococcus cause clinical diseases.

Human rhinoviruses (HRV) mostly cause mild and self-limiting upper respiratory tract infections. We report 2 infants with acute respiratory failure requiring mechanical ventilation, 1 of whom deteriorated to death. The causal pathogen was HRV group A confirmed by multiplex-PCR. In Korea, this is the first report of severe respiratory failure caused by HRV group A during the same season.

9.Human Rhinoviruses: the Forgotten but Still Important Viruses.
Journal of Bacteriology and Virology 2017;47(3):111-121
Human rhinoviruses (HRVs) are responsible for many of the characteristic symptoms of the common cold, such as a sore throat, runny nose, nasal congestion, sneezing, and coughing. However, despite the high detection rate in children, most HRV infections are asymptomatic. As a result, these viruses are generally ignored, even though a close association between HRV infections in early life and the subsequent induction of asthma has been reported. Therefore, it is necessary to conduct further research into HRV diagnostics, treatments, epidemiology, and vaccines. This review describes recent studies of HRVs, including their genomic diversity, surveillance systems, taxonomy, and immune responses, as well as vaccines.
