Various follow-up studies of children hospitalized with bronchiolitis caused by respiratory syncytial virus have demonstrated that a significant proportion of infants (50%) have recurrent wheezing during childhood. Nevertheless, the relationship between these two entities, if any, has not been established. In order to explain this observation, several hypotheses have been proposed. The first suggests that some children could have an individual predisposition to bronchiolitis caused by respiratory syncytial virus and recurrent wheezing. The virus could be a marker of this condition, and the individual predisposition could in turn be related to an individual hypersensitivity to common allergens (atopy), airway hyperreactivity, or to some disorder related to pulmonary anatomy or physiology that was present before the acute episode of bronchiolitis. Another hypothesis proposes that respiratory syncytial virus could be directly responsible for recurrent wheezing. During an episode of bronchiolitis, the damage in the airway mucosa caused by the vital inflammatory response to infection contributes to sensitivity to other allergens or exposes irritant receptors, resulting in recurrent wheezing. For this review, we analyzed the studies that discuss these hypotheses with the purpose of clarifying the mechanisms for the important issue of recurrent wheezing in childhood.

Background: Respiratory syncytial virus (RSV) is the most common pathogen of acute bronchiolitis in children, which sometimes triggers the development of recurrent wheezing and increases the risk of childhood asthma.Methods: We enrolled 425 children who were diagnosed with RSV-infected bronchiolitis at the department of pulmonology, Children's Hospital Zhejiang University School of Medicine in 2011. Long-term follow-up was performed to explore the consequence of bronchiolitis on subsequent recurrent wheezing and asthma.Results: Of 425 patients, 266 cases completed the entire follow-up, the mean age of onset was 4.9 (3.3) months, and the male-to-female ratio was 2.5. The mean birth weight of all patients was 3.22 (0.63) kg, and the number of patients who had a history of cesarean section was 148. According to the outcome of follow-up, 36 were in the recurrent wheezing (RW) group, 65 were in the asthma (AS) group, and the remaining 165 were in the completely recovered (CR) group. The age of onset was older and the birth weights were higher in the AS group than those in the CR group (P < 0.05). And the higher proportion of cesarean sections was higher in the RW group than that in the CR group (P < 0.05). Furthermore, we found a remarkable increasing of serum IgE in the AS groups than that in the CR group (P < 0.01). Multiple logistic regression analysis showed that the cesarean section was the risk factor for the development of recurrent wheezing and the higher birth weight was the risk factor for the development of asthma.Conclusion: RSV bronchiolitis might increase the incidence of recurrent wheezing and asthma. Allergic constitution was an important prerequisite for the occurrence of asthma, and related risk factor such as cesarean section can only increase recurrent wheezing to a certain extent within a certain period of time. And we also find higher birth weight and older onset age for those who develop asthma, which should be verified in the future.

Background: Recurrent wheezing is a common clinical manifestation in childhood, and respiratory syncytial virus infection is a well-known risk factor. However, the genetic background favoring the development of recurrent wheezing is not fully understood. A possible role of macrophage receptor with collagenous gene (MARCO) polymorphism has been recently proposed.Objective: To investigate a correlation between MARCO rs1318645 polymorphisms and susceptibility to recurrent wheezing during childhood.Methods: We prospectively recruited 116 infants, of which 58 with respiratory syncytial virus bronchiolitis and 58 controls hospitalized at Regina Margherita Children's Hospital, Turin, Italy, between November 2014 and April 2015. All subjects were investigated for MARCO rs1318645 polymorphisms in the first period of life. Genotyping of rs1318645 was carried out by TaqMan mismatch amplification mutation assay real-time polymerase chain reaction procedure. Subjects were then enrolled in a 5-year follow-up study to monitor the occurrence of wheezing and respiratory infections.Results: The analysis of MARCO rs1318645 of allelic frequencies shows an increasingly significant risk to develop recurrent infection (p = 0.00065) and recurrent wheezing (p = 0.000084) with a wild-type C allele compared with a G allele. No correlation was found between wheezing and past respiratory syncytial virus infection (p = 0.057) and for a history of atopy in the family (p = 0.859).Conclusion: Our finding showed that subjects with C allelic MARCO rs1318645 polymorphism are at higher risk for recurrent infection and wheezing episodes during the first 5 years of life. Future studies of genetic associations should also consider other types of polymorphisms.

Abstract Background: Wheezing in infancy is very common. RSV infection can cause recurrent wheezing. The aim of this study was to explore the risk factors of recurrent wheezing in children under 3 years of age after RSV infection. Methods：We chose children with initial wheezing before 3 years of age who were hospitalized for medical treatment. Wheezing frequency was determined by follow-up at 1 week, 1 month, 3 months, 6 months, and 1 year. Information such as birth status, age, sex, preterm, mode of delivery, birth order, eczema history, personal allergy history, family allergy history, passive smoking, and place of residence (urban/rural) was collected. Total serum IgE level, serum allergen testing, routine blood tests, C-reactive protein level, procalcitonin level, respiratory pathogens tests, sputum culture, chest radiography or computed tomography were performed in all patients. The correlation between each factor and wheezing recurrence was evaluated. Results: A total of 259 children were included in the study. They were divided into single recurrence, multiple recurrences, and no recurrence groups. There were significant differences between the single recurrence and multiple recurrences groups in terms of personal allergy history, passive smoking, total serum IgE level, age, hospital stay duration, and wheezing duration (p<0.05). The percentage of children with a personal allergy history in the multiple recurrences group was significantly higher than that of children in the single recurrence and no recurrence groups (p=0.031 and 0.008, respectively). The age of children in the multiple recurrences group was significantly lower than that of children in the single recurrence group (p=0.000). The cost of re-hospitalization in the multiple recurrences group was significantly higher than that in the single recurrence and no recurrence groups (p=0.000 and 0.000, respectively). Conclusions: Children with a personal allergy history were more likely to have wheezing episodes. The frequency of wheezing in children under 3 years of age within 1 year of a respiratory syncytial virus infection was related to age. The younger the age at the time of the onset of wheezing, the more wheezing recurrences in the following year.

12042 Background: The COVID-19 pandemic has impacted the well-being of people not only due to the disease but also because of stay-at-home orders, social distancing, unemployment, and different kinds of loses. Older adults have particularly suffered during the pandemic, with increased health-related concerns and anxiety leading to increased vulnerability. However, little is known about the effects of the pandemic on older adults with cancer living in developing countries. They are facing issues related to their diagnosis and treatment, as well as the effects of the pandemic on their care and on the well-being of their families. To improve care for this vulnerable population, we studied the concerns and difficulties associated with COVID-19 among older Mexican adults with cancer. Methods: We included patients age ≥65 with the 10 most common tumors in Mexico according to GLOBOCAN and within 3-24 months of cancer diagnosis at two public hospitals in Mexico City. Patients were contacted telephonically and asked to complete a survey reporting the difficulties encountered during the COVID-19 pandemic and to rate their concerns associated with cancer care management using a 0-10 Likert-type scale, with higher ratings meaning increased concerns. Focused interviews were used to describe the individual experience of selected patients and their relatives related to COVID-19 and cancer care. Results: Between April 20, 2020 and December 1, 2021, 67 patients (mean age 71.9, min 65, max 90; 35.8% female; 62.7% living with a partner) were included. The most common tumors were prostate (43%), colon (16%), and lung (12%). 46% had Stage IV disease, and 61% had a life expectancy of more than a year. Twenty-five percent of patients reported encountering at least one difficulty in obtaining cancer care due to the COVID-19 pandemic. 43% of the patients reported difficulties with accessing follow-up cancer care; 39% reported issues with obtaining medications, including chemotherapy; and 34% reported problems obtaining medical care in general, including oncology visits. Regarding concerns, 33% of the patients reported being “very worried” or “extremely worried” about the COVID-19 pandemic. The most relevant concerns were related to getting infected with COVID-19 (or having a family member who became infected) (mean rating 7.9, SD 2.9); not being able to pay for cancer treatments or medical care (mean rating 6.9, SD 3.5); and worsening of cancer due to delayed care during the pandemic (mean rating 6.6, SD 3.7). Conclusions: A significant proportion of older adults with cancer in Mexico faced difficulties obtaining cancer treatment and follow-up care during the COVID-19 pandemic. Their most relevant concerns included getting infected, financial losses, and progression of disease. Creating systems to provide continued cancer care for vulnerable populations in developing countries is essential to face the COVID-19 pandemic.

SUMMARYThe aim of this study was to describe the incidence and risk factors for respiratory morbidity during the 12-month period following the first respiratory syncytial virus (RSV) season in 242 preterm infants [<33 weeks gestational age (GA)] without bronchopulmonary dysplasia and 201 full-term infants (39–41 weeks GA) from the French CASTOR study cohort. Preterm infants had increased respiratory morbidity during the follow-up period compared to full-terms; they were more likely to have wheezing (21% vs. 11%, P = 0·007) and recurrent wheezing episodes (4% vs. 1%, P = 0·049). The 17 infants (14 preterms, three full-terms) who had been hospitalized for RSV-confirmed bronchiolitis during their first RSV season had significantly more wheezing episodes during the follow-up period than subjects who had not been hospitalized for RSV-confirmed bronchiolitis (odds ratio 4·72, 95% confidence interval 1·71–13·08, P = 0·003). Male gender, birth weight <3330 g and hospitalization for RSV bronchiolitis during the infant's first RSV season were independent risk factors for the development of wheezing episodes during the subsequent 12-month follow-up period.
