Rhinovirus (RV) is an RNA virus that causes more than 50% of upper respiratory tract infections in humans worldwide. Together with Respiratory Syncytial Virus, RV is one of the leading causes of viral bronchiolitis in infants and the most common virus associated with wheezing in children aged between one and two years. Because of its tremendous genetic diversity (>150 serotypes), the recurrence of RV infections each year is quite typical. Furthermore, because of its broad clinical spectrum, the clinical variability as well as the pathogenesis of RV infection are nowadays the subjects of an in-depth examination and have been the subject of several studies in the literature. In fact, the virus is responsible for direct cell cytotoxicity in only a small way, and it is now clearer than ever that it may act indirectly by triggering the release of active mediators by structural and inflammatory airway cells, causing the onset and/or the acute exacerbation of asthmatic events in predisposed children. In the present review, we aim to summarize the RV infection’s epidemiology, pathogenetic hypotheses, and available treatment options as well as its correlation with respiratory morbidity and mortality in the pediatric population.

Abstract Background Acute respiratory infections (ARIs) are among the leading causes of hospitalization in children. Understanding the local dominant viral etiologies is important to inform infection control practices and clinical management. This study aimed to investigate the viral etiology and epidemiology of respiratory infections among pediatric inpatients in Macao. Methods A retrospective study using electronic health records between 2014 and 2017 at Kiang Wu Hospital was performed. Nasopharyngeal swab specimens were obtained from hospitalized children aged 13 years or younger with respiratory tract diseases. xMAP multiplex assays were employed to detect respiratory agents including 10 respiratory viruses. Data were analyzed to describe the frequency and seasonality. Results Of the 4880 children enrolled in the study, 3767 (77.1%) were positive for at least one of the 13 viral pathogens tested, of which 2707 (55.5%) being male and 2635 (70.0%) under 2 years old. Among the positive results, there were 3091 (82.0%) single infections and 676 (18.0%) multiple infections. The predominant viruses included human rhinovirus/enterovirus (HRV/EV 27.4%), adenovirus (ADV, 15.8%), respiratory syncytial virus B (RSVB, 7.8%) and respiratory syncytial virus A (RSVA, 7.8%). The detection of viral infection was the most prevalent in autumn (960/1176, 81.6%), followed by spring (1095/1406, 77.9%), winter (768/992, 77.4%), and summer (944/1306, 72.3%), with HRV/EV and ADV being most commonly detected throughout the 4 years of study period. The detection rate of viral infection was highest among ARI patients presented with croup (123/141, 87.2%), followed by lower respiratory tract infection (1924/2356, 81.7%) and upper respiratory tract infection (1720/2383, 72.2%). FluA, FluB and ADV were positive factors for upper respiratory tract infections. On the other hand, infection with RSVA, RSVB, PIV3, PIV4, HMPV, and EV/RHV were positively associated with lower respiratory tract infections; and PIV1, PIV2, and PIV3 were positively associated with croup. Conclusions This is the first study in Macao to determine the viral etiology and epidemiology of pediatric patients hospitalized for ARIs. The study findings can contribute to the awareness of pathogen, appropriate preventative measure, accurate diagnosis, and proper clinical management of respiratory viral infections among children in Macao.

Antimicrobial resistance is an emerging global health threat. Misuse and abuse of antibiotics are of particular concern in the pediatric population. Since management of childhood illnesses depends considerably on parents’ perceptions, the objectives of this study were to report parents’ perspectives and assess their practices toward antibiotics used for upper respiratory tract infections (URTIs) in children. Using a cross-sectional design, anonymous structured questionnaires were completed by 1,037 parents in public and private schools across Lebanon’s largest governorate. Descriptive statistics were used to report participants’ responses. A multivariate analysis was performed to identify factors affecting knowledge and malpractice related to antibiotic use. Significant misconceptions and malpractices were identified among parents. For instance, 33.9% of parents considered that antibiotics are helpful in treating common cold among children and 36.2% believed antibiotics expedite the recovery of their child with common cold infection. Moreover, there was a lack of knowledge concerning antibiotic coverage, since 37.9% of the respondents believed that antibiotics treat viral infections and 21.5% were neutral toward this question. Around 20% of the participants believed they can reduce the dose of antibiotics if the child gets better. Significant factors associated with poor knowledge and misuses were parents’ lower educational and socioeconomic levels. Despite extensive evidence on the limited role of antibiotics in URTIs, parents in Lebanon continue to misuse them. More concerted efforts are needed to improve parents’ knowledge and practices with regard to the rational use of antibiotics.

Postviral olfactory disorder refers to the sensorineural olfactory loss caused by upper respiratory tract infections. With the increasing awareness of olfactory or gustatory dysfunction as a potential early symptom of coronavirus disease 2019, postviral olfactory disorder has been attracting much attention. Postviral olfactory disorder is the most common type of olfactory disorder, especially among women aged over 50 years. Systemic or topical corticosteroids have commonly been used for treating this disorder, but the mechanism of corticosteroid action is unclear. Other medical treatment options such as alpha-lipoic acids and caroverine that stimulate nerve growth factor expression or prevent glutamatergic neurotoxicity have also been used. Although these drugs have been found to be useful in the treatment of postviral olfactory disorder in previous studies, the efficacy has not been statistically proven through a meta-analysis. Recently, olfactory training has been introduced in the treatment strategy for postviral olfactory disorder. It is a safe option without side effects that can be used for treating olfactory disorders caused by upper respiratory tract infections. Further rigorous studies are needed to determine the efficacy of the combination of drug treatment and olfactory training.

Abstract Background Invasive aspergillosis (IA) is a serious infectious complication following hematopoietic cell transplantation (HCT). Few studies have reported respiratory viral infections (RVIs) as a risk factor for developing IA, and data regarding specific viruses is sparse. We examined whether specific respiratory viruses were associated with increased risk of developing IA post-HCT. Methods In a longitudinal surveillance study of RVIs among allogeneic HCT recipients conducted 2005–2010, weekly post-HCT nasal washes were collected through day 100, then every 3 months, and whenever respiratory symptoms occurred through 1 year post-HCT. Nasal and bronchoalveolar lavage (BAL) samples were tested by multiplex PCR for respiratory syncytial virus (RSV), parainfluenza viruses (PIV)1–4, influenza A/B, human metapneumovirus, adenovirus (ADV), and human rhinoviruses, and coronaviruses. Only respiratory virus detections with symptoms were counted as RVI. Separate Cox proportional hazards models were used to examine adjusted associations between each RVI and the development of first proven/probable IA by 1-year post-HCT. Results Among 437 patients who survived >28 days following HCT, 39 patients developed IA by 1-year post-HCT (median 87 days, range 5–283). After adjusting for age at HCT, neutropenia, high-grade CMV viremia, and HLA status (matched related vs. others) or severe acute graft-versus-host disease (GVHD Grade 0–2 vs. 3–4), RSV and ADV upper respiratory tract infections (URTI) were associated with increased risk of developing IA (figure). Detection of any respiratory virus in the BAL was associated with IA (P < 0.001). Conclusion RSV and ADV URTI are significant risk factors for development of IA post-HCT; the association between PIV URTI and development of IA approached statistical significance. Viral lower respiratory tract infection was associated with IA. Our data provide a rationale to assess IA as an endpoint in preventive studies of novel agents for respiratory viruses and further emphasize the importance of effective infection prevention practices for RVIs after HCT.

ABSTRACT Human respiratory syncytial virus (RSV) belongs to the recently defined Pneumoviridae family, Orthopneumovirus genus. It is a negative sense, single stranded RNA virus that results in epidemics of respiratory infections that typically peak in the winter in temperate climates and during the rainy season in tropical climates. Generally, one of the two genotypes (A and B) predominates in a single season, alternating annually, although regional variation occurs. RSV is a cause of disease and death in children, older people, and immunocompromised patients, and its clinical effect on adults admitted to hospital is clarified with expanded use of multiplex molecular assays. Among adults, RSV produces a wide range of clinical symptoms including upper respiratory tract infections, severe lower respiratory tract infections, and exacerbations of underlying disease. Here we discuss the latest evidence on the burden of RSV related disease in adults, especially in those with immunocompromise or other comorbidities. We review current therapeutic and prevention options, as well as those in development.

AbstractA considerable amount of effort has been put into the reduction of the overuse of antibiotics and reduction in radiographic studies in the pediatric population. Infections within the ear, nose, and throat and in cervical regions are a frequent source of antibiotic use in children. Quality improvement projects creating clear care pathways have been important to delineate which imaging may be most helpful.

AbstractHuman respiratory syncytial virus (RSV) is a negative sense single-stranded RNA virus that can result in epidemics of seasonal respiratory infections. Generally, one of the two genotypes (A and B) predominates in a single season and alternate annually with regional variation. RSV is a known cause of disease and death at both extremes of ages in the pediatric and elderly, as well as immunocompromised populations. The clinical impact of RSV on the hospitalized adults has been recently clarified with the expanded use of multiplex molecular assays. Among adults, RSV can produce a wide range of clinical symptoms due to upper respiratory tract infections potentially leading to severe lower respiratory tract infections, as well as exacerbations of underlying cardiac and lung diseases. While supportive care is the mainstay of therapy, there are currently multiple therapeutic and preventative options under development.
