Randomised controlled trial of budesonide for the prevention of post-bronchiolitis wheezing. (1/187)

BACKGROUND: Previous studies suggest that recurrent episodes of coughing and wheezing occur in up to 75% of infants after acute viral bronchiolitis. AIM: To assess the efficacy of budesonide given by means of a metered dose inhaler, spacer, and face mask in reducing the incidence of coughing and wheezing episodes up to 12 months after acute viral bronchiolitis. METHODS: Children under the age of 12 months admitted to hospital with acute viral bronchiolitis were randomised to receive either budesonide or placebo (200 microg or one puff twice daily) for the next eight weeks. Parents kept a diary card record of all episodes of coughing and wheezing over the next 12 months. RESULTS: Full follow up data were collected for 49 infants. There were no significant differences between the two study groups for the number of infants with symptom episodes up to six months after hospital discharge. At 12 months, 21 infants in the budesonide group had symptom episodes compared with 12 of 24 in the placebo group. The median number of symptom episodes was 2 (range, 0-13) in those who received budesonide and 1 (range, 0-11) in those who received placebo. Because there is no pharmacological explanation for these results, they are likely to be caused by a type 1 error, possibly exacerbated by there being more boys in the treatment group. CONCLUSION: Routine administration of budesonide by means of a metered dose inhaler, spacer, and face mask system immediately after acute viral bronchiolitis cannot be recommended.  (+info)

Association of fever and severe clinical course in bronchiolitis. (2/187)

Little attention has been given to the relation between fever and the severity of bronchiolitis. Therefore, the relation between fever and the clinical course of 90 infants (59 boys, 31 girls) hospitalised during one season with bronchiolitis was studied prospectively. Fever (defined as a single recording > 38.0 degrees C or two successive recording > 37.8 degrees C) was present in 28 infants. These infants were older (mean age, 5.3 v 4.0 months), had a longer mean hospital stay (4.2 v 2.7 days), and a more severe clinical course (71.0% v 29.0%) than those infants without fever. Radiological abnormalities (collapse/consolidation) were found in 60. 7% of the febrile group compared with 14.8% of the afebrile infants. These results suggest that monitoring of body temperature is important in bronchiolitis and that fever is likely to be associated with a more severe clinical course and radiological abnormalities.  (+info)

IL-8 and neutrophil elastase levels in the respiratory tract of infants with RSV bronchiolitis. (3/187)

The aim of this study was to determine whether interleukin (IL)-8 is released within the upper respiratory tract of infants during respiratory syncytial virus (RSV) bronchiolitis and whether the large number of polymorphonuclear neutrophils (PMNs) present in the respiratory tract of these infants are contributing to the inflammation through release of inflammatory mediators. Twenty-seven infants with acute bronchiolitis were recruited during one winter epidemic and 20 infant control subjects were recruited from a cohort participating in a community-based vaccine study. Samples of airways fluid were obtained using nasal lavage. The lavage fluid was spun to remove the cells, and the supernatant was stored at -70 degrees C. The supernatants were subsequently assayed for the presence of IL-8, total human neutrophil elastase (HNE) and neutrophil elastase activity. In the children with bronchiolitis compared with control infants, elevated levels of IL-8 (median (range) 1.53 (0-153) versus 0 (0-5.6) ng x mL(-1)) HNE (136 (32-694) versus 14 (0-516) ng x mL(-1)) and elastase activity (4 (1-220) versus 1 (0-339) mU x mL(-1)) were found. These results indicate that interleukin-8 is released in the upper respiratory tract in response to respiratory syncytial virus infection and suggest that polymorphonuclear neutrophil products are playing an important role in the inflammatory response to respiratory syncytial virus infection in infants with acute bronchiolitis. This contrasts with the predominantly eosinophilic response evident in atopic upper and lower respiratory tract disease.  (+info)

Peripheral blood cytokine responses and disease severity in respiratory syncytial virus bronchiolitis. (4/187)

The role of cellular immunity in disease severity in respiratory syncytial virus (RSV) bronchiolitis is largely unknown. This study investigated the association between disease severity and systemic cytokine responses in hospitalized ventilated and nonventilated RSV bronchiolitis patients. In whole blood cultures stimulated with phytohaemagglutinin (PHA), lymphoproliferative responses and interferon (IFN)-gamma and interleukin (IL)-4 production during acute illness were measured. In addition, plasma cytokines were measured. Measurements were repeated in the convalescent phase, 3-4 weeks after admission. Fifty patients were included. The median age in ventilaled patients was significantly lower than in nonventilated patients (1 versus 4 months, p<0.05). In comparison with nonventilated patients, the ventilated patients had significantly lower lymphoproliferative responses and a lower production of IFN-gamma and IL-4. In fact, IFN-gamma and IL-4 production in ventilated patients was almost completely undetectable. Plasma IL-8 levels in ventilated patients were significantly higher than in nonventilated patients. In the convalescent phase, lymphoproliferative and cytokine responses as well as plasma IL-8 levels were normal in both patient groups. Since RSV bronchiolitis is associated with the subsequent development of asthma, the possible skewing of the T-helper (Th1/Th2) cytokine balance was investigated. This was found neither in the acute nor in the convalescent phase. In conclusion, the data indicate that depressed lymphocyte function and elevated plasma interleukin-8 levels are markers of severe disease. It is suggested that age and maturation related immune mechanisms could explain the occurrence of severe respiratory syncytial virus bronchiolitis requiring mechanical ventilation in young infants.  (+info)

Effects of respiratory syncytial virus persistence on airway responsiveness and inflammation in guinea-pigs. (5/187)

Recurrent wheezing and asthma often develop after acute respiratory syncytial virus (RSV) bronchiolitis, but the mechanisms of these sequelae are poorly understood. Using a guinea-pig model of human RSV lung infection, the effects of long-term viral persistence on three hallmarks of asthma: nonspecific airway responsiveness, airway inflammation and airway remodelling were examined. Guinea-pigs were studied 100 days after intranasal instillation of either human RSV or uninfected vehicle, using: 1) acetylcholine challenge to test for airway hyperresponsiveness (AHR); 2) lung histology to quantify the numbers of airway eosinophils and metachromatic cells (mast cells/basophils); 3) airway morphometry of the areas of the airway subepithelial connective tissue, smooth muscle and adventitia, to test for airway remodelling; and 4) immunohistochemistry to identify lung cells containing RSV antigens. The RSV-inoculated group had significantly elevated AHR and airway eosinophils compared to uninfected control animals (p<0.05). There were no significant differences between the two groups in terms of numbers of airway metachromatic cells, or the areas of subepithelial connective tissue, smooth muscle or adventitia. Viral proteins were identified by immunohistochemistry within several types of lung cells. In conclusion, long-term persistence of respiratory syncytial virus in the guinea-pig lung is associated with airway hyperresponsiveness and airway eosinophilia, and these changes may be pertinent to the pathogenesis of postbronchiolitis wheezing and asthma in children.  (+info)

Randomised placebo controlled trial of nebulised corticosteroids in acute respiratory syncytial viral bronchiolitis. (6/187)

OBJECTIVE: To evaluate short and long term effects of giving nebulised budesonide early in respiratory syncytial viral (RSV) bronchiolitis. DESIGN: A multicentre randomised double blind placebo controlled trial. SUBJECTS: Infants admitted to hospital with their first episode of RSV positive bronchiolitis. INTERVENTION: Randomisation to receive either 1 mg of nebulised budesonide (Bud) or placebo (Pla) twice daily from admission until 2 weeks after discharge. Follow up was for 12 months. MAIN OUTCOME MEASURES: Duration of hospital admission, time taken to become symptom free, re-admission rates, general practitioner consultation rates, and use of anti-wheeze medication during follow up. RESULTS: 161 infants were studied. Both arms were similar with respect to initial clinical severity, age, sex, socioeconomic class, and tobacco exposure. Median time from first nebulisation to discharge: Bud and Pla, 2 days. Median number of days for 50% of infants to be symptom free for 48 hours: Bud, 10 days; Pla, 12 days. Respiratory re-admission rates in the 12 month follow up: Bud, 16%; Pla, 18%; median difference (95% confidence interval (CI)), -2 (-14 to 10). Median respiratory related general practitioner attendances: Bud, 4.0; Pla, 4.5; median difference (95% CI), -1 (-2 to 0). Percentage of infants receiving at least one prescription for anti-wheeze medication during follow up, corticosteroids: Bud, 50%; Pla, 60%; difference (95% CI), -10 (-26 to 6); bronchodilators: Bud, 60%; Pla, 67%; difference (95% CI), -7 (-22 to 8). CONCLUSIONS: There are no short or long term clinical benefits from the administration of nebulised corticosteroids in the acute phase of RSV bronchiolitis.  (+info)

No objective benefit from steroids inhaled via a spacer in infants recovering from bronchiolitis. (7/187)

A double-blind randomized placebo-controlled trial was conducted to investigate the efficacy of 3 months' inhaled steroids delivered via a spacer device with face mask attachment to infants recovering from bronchiolitis. Forty-eight previously healthy infants recovering from their first documented episode of acute bronchiolitis were randomized to receive 150 microg fluticasone propionate (FP) b.i.d. or placebo delivered via the Babyhaler spacer. Longitudinal assessments were performed on seven occasions over 1 yr based on symptom diaries and health records, clinical examinations, overnight cough recordings and oxygen saturation readings. Lung function was measured 6 months after hospital discharge. Forty-three infants completed the trial (FP 21, placebo 22). There were no significant differences in the three objective end-points measured, recorded night cough, oxygen saturation and lung function test results. Symptom scores were low in both the FP and placebo groups with the absence of (0) or mild (1) symptoms > or =90% of the trial days. No statistical differences in symptom frequency, use of rescue respiratory medications or hospital admissions between treatment groups were found throughout the trial or follow-up periods. In conclusion, the use of inhaled fluticasone propionate in infants recovering from acute bronchiolitis cannot be recommended.  (+info)

The diagnostic and therapeutic approach to acute bronchiolitis in hospitalized children in Israel: a nationwide survey. (8/187)

BACKGROUND: Bronchiolitis caused by respiratory syncytial virus is one of the major causes of hospitalization in young children, especially during the winter. Recent evidence has shown that pharmacological treatment, especially nebulized epinephrine, in addition to the traditional supportive treatment, can alleviate symptoms and shorten hospitalization, but this approach is not yet widespread. OBJECTIVES: To determine whether the management of bronchiolitis in Israel is moving toward a stronger emphasis on pharmacological care. METHODS: A questionnaire on the diagnosis and management of bronchiolitis was completed by 27 heads of pediatric departments throughout Israel. The questionnaire dealt with the frequency of usage of diagnostic and selected therapeutic procedures. RESULTS: Chest X-ray and arterial blood gases are commonly used as a diagnostic aid in more than 75% of the departments, and antibiotics are prescribed routinely in 24%. Corticosteroids are still in use: 48% use systemic steroids, and 19% nebulized steroids. Nebulized epinephrine is used in 22% of the departments, while nebulized beta-agonists are used frequently in two-thirds of the departments. CONCLUSIONS: Despite convincing data that beta-agonists and steroids have no positive effect on the outcome of bronchiolitis on the one hand, and that nebulized epinephrine has advantages in children on the other, we found significant use of the former two agents and sparse use of the latter. Greater awareness is needed among pediatricians, and measures should be introduced to incorporate the new recommendations, with further study of the effect of the old and new drugs on bronchiolitis.  (+info)

Reverse transcription-polymerase chain reaction was used to detect segments of the M (matrix), N (nucleoprotein), and F (fusion) genes of human metapneumovirus in bronchoalveolar fluid from 30 infants with severe respiratory syncytial virus bronchiolitis. Seventy percent of them were coinfected with metapneumovirus. Such coinfection might be a factor influencing the severity of bronchiolitis.
Acute viral bronchiolitis constitutes the principal cause of acute lower respiratory tract infections in infants and children in Nord America. Every year 11% of infants younger than 1 year and 6% of those between 1 and 2 years are affected. Acute viral bronchiolitis is characterized by a first episode of respiratory distress associated to rhinorrhea, cough and fever, other symptoms such as vomiting, use of accessory intercostal muscles and irritability can be present. Mild symptoms presentation in bronchiolitis is very common, these patients do not require treatment or testing, only appropriate information on how to ameliorate respiratory symptoms and a well list of alarm signs for parents are frequently enough to send the patient home.. Increasing workload in the ED is a national worry after the last 20 years. Between October and April, this phenomena is seen each year due to cold and influenza season. From an economic perspective along with a lack in human resources, new strategies have to be ...
Acute viral bronchiolitis is the principal lower respiratory tract infection in infants worldwide, 10% of canadian infants are affected each year. It is characterized by a first episode of difficulty to breathe, preceded by symptoms of fever, rhinorrhea and cough. The only accepted treatment for bronchiolitis is nasal cleaning, hydration and oxygen administration. Multiple studies have documented variation in diagnostic testing, clinical scores used and different treatment modalities. This suggests a lack of consensus on the diagnosis, on criteria for hospitalization and on treatment. Nebulized 3% hypertonic saline solution has been proposed as a potential treatment for the reduction in the severity of respiratory symptoms and the rate of admission in bronchiolitis, it has never been studied alone and the effect on the rate of admission has been little studied.. We propose a randomized double blind multicenter clinical trial on infants 6 weeks to 12 months old with moderate or severe ...

Background Respiratory syncytial virus (RSV) is a major cause of viral bronchiolitis in infants worldwide, and environmental, viral and host factors are all of importance for disease susceptibility and severity. To study the systemic host response to this disease we used the microarray technology to measure mRNA gene expression levels in whole blood of five male infants hospitalised with acute RSV, subtype B, bronchiolitis versus five one year old male controls exposed to RSV during infancy without bronchiolitis. The gene expression levels were further evaluated in a new experiment using quantitative real-time polymerase chain reaction (QRT-PCR) both in the five infants selected for microarray and in 13 other infants hospitalised with the same disease. Results Among the 30 genes most differentially expressed by microarray nearly 50% were involved in immunological processes. We found the highly upregulated interferon, alpha-inducible protein 27 (IFI27) and the highly downregulated gene ...
|jats:p|In 1995, the European Society for Paediatric Infectious Diseases (ESPID) carried out a survey of its members to assess the variation in management of respiratory syncytial virus (RSV) bronchiolitis. The aim of the current study was to carry out a similar survey 20 years later to assess how the management had changed. An electronic, structured, English language survey, based on the United Kingdom National Institute for Health and Care Excellence (NICE) bronchiolitis draft guideline, was sent to ESPID members in March 2015. Questions asked included information on treatment practices of infants with bronchiolitis and doctor demographics. We received responses from 135 doctors (14% of the ESPID members) who worked in 115 hospitals. 56% of the doctors used a written guideline to manage bronchiolitic infants. All doctors stated that they isolated individually or in cohorts all hospitalised bronchiolitis infants. The level of oxygen saturation suggested as an indication to administer supplemental
The robust inflammatory response associated with RSV infection does not contribute to the severity of RSV bronchiolitis any more than it contributes to the severity of non-RSV bronchiolitis. Elevated levels of proinflammatory mediators IL-6, IL-8, IFN-gamma, and MIP-1beta, as well as of the regulato …
Bronchiolitis is a viral-induced lower respiratory tract infection that occurs predominantly in children < 2 years of age, particularly infants. Many viruses have been proven or attributed to cause bronchiolitis, including and most commonly the respiratory syncytial virus (RSV) and rhinovirus. RSV is responsible for more severe disease and complications (including hospitalisation) in bronchiolitis patients. Whereas bronchiolitis is exclusively due to respiratory viral infections, with little evidence of bacterial co-infection, the former could nevertheless predispose to superimposed bacterial infections. Although data support an interaction between RSV and pneumococcal superimposed infections, it should be noted that this specifically refers to children who are hospitalised with RSV-associated pneumonia, and not to children with bronchiolitis or milder outpatient RSV-associated illness. As such, empiric antibiotic treatment against pneumococcus in children with RSV-associated pneumonia is only

Single nucleotide polymorphisms (SNPs) in AOE and NRF2 genes have been associated with various lung disorders. To test whether specific NRF2 and/or AOE gene SNPs in children with RSV lower respiratory tract infection were associated with disease severity, one hundred and forty one children ,24 month of age with bronchiolitis were assessed for seven AOE and two NRF2 SNPs, and data were correlated with disease severity, which was determined by need of oxygen ...
BACKGROUND: Respiratory syncytial virus (RSV) is the most important pathogen causing severe lower respiratory tract infection (LRTI) in infants. Epidemiologic and basic studies suggest that vitamin D may protect against RSV LRTI. OBJECTIVE: To determine the association between plasma vitamin D concentrations at birth and the subsequent risk of RSV LRTI. DESIGN: A prospective birth cohort study was performed in healthy term neonates. Concentrations of 25-hydroxyvitamin D (25-OHD) in cord blood plasma were related to RSV LRTI in the first year of life, defined as parent-reported LRTI symptoms in a daily log and simultaneous presence of RSV RNA in a nose-throat specimen. RESULTS: The study population included 156 neonates. Eighteen (12%) developed RSV LRTI. The mean plasma 25-OHD concentration was 82 nmol/L. Overall, 27% of neonates had 25-OHD concentrations < 50 nmol/L, 27% had 50-74 nmol/L and only 46% had 25-OHD 75 nmol/L. Cord blood 25-OHD concentrations were strongly associated with ...

Bronchiolitis is the most common acute infection of the airways and lungs during the first years of life. It is caused by viruses, the most common being respiratory syncytial virus. The illness starts similar to a cold, with symptoms such as a runny nose, mild fever and cough. It later leads to fast, troubled and often noisy breathing (for example, wheezing). While the disease is often mild for most healthy babies and young children, it is a major cause of clinical illness and financial health burden worldwide. Hospitalisations have risen in high-income countries, there is substantial healthcare use and bronchiolitis may be linked with preschool wheezing disorders and the child later developing asthma.. There is variation in how physicians manage bronchiolitis, reflecting the absence of clear scientific evidence for any treatment approach. Anti-inflammatory drugs like glucocorticoids (for example, prednisolone or dexamethasone) have been used based on apparent similarities between bronchiolitis ...

Humidified low-flow oxygen (0.5 - 3 litres/minute) applied by nasal prongs is effective for hypoxic children. Nasal prongs give a maximum inspired oxygen of 28 - 35% except in small infants, when higher oxygen concentrations may be obtained. Headbox oxygen is an alternative that is well tolerated by young infants. It requires no humidification, but high flow and a mixing device are needed to ensure that the correct oxygen concentration is delivered. However, there is wastage of oxygen and the delivered oxygen concentration (FiO2) is unpredictable. Facemask oxygen delivers between 28% and 65% oxygen at a flow rate of 6 - 10 l/min. In severely hypoxic infants who are not ventilated, oxygen should be administered using a polymask, which enables FiO2 concentrations of 60 - 80% to be achieved. Oxygen should be weaned when the child improves clinically and with resolution of hypoxia. Rapid short-acting bronchodilator therapy has shown modest benefits in the treatment of bronchiolitis.20 ...
Discussion. The present study shows that AVB in the 1st year of life was a risk factor for asthma in children and significantly increases when associated with a parental history of asthma. Exposure to AVB and other multiple environmental factors is important for the development of the disease, especially in predisposed children.17 Respiratory infections by viruses and AVB are more common in infants, and have been associated with risk of asthma, as they are related to its pathogenesis and the triggering of exacerbations.17,18 Although some infections caused by influenza and parainfluenza viruses can inhibit the development of asthma, despite repeated upper airway respiratory infections in the first two years of the childs life, other infections by RSV and rhinovirus may favor the onset of asthma and atopy.7,19,20 There are several hypotheses to explain the mechanisms involved in the association between viral infection, persistent dyspnea, and asthma: (i) induction of inflammation typical of ...
In RSV bronchiolitis, neutrophils, account for ,80% of cells recovered from airways in bronchoalveolar lavage (BAL) fluid. We investigated neutrophil activation and toll-like receptor (TLR) expression in the blood and lungs of infants with severe RSV bronchiolitis.. Methods: BAL and (blood) samples were collected from 24 (16) preterm and 23 (15) term infants, ventilated with RSV bronchiolitis, and 12 (8) control infants. We measured protein and mRNA expression of CD11b, myeloperoxidase (MPO) and TLR 2,4,7,8,9 in neutrophils.. Results: Blood neutrophils had more CD11b in preterm and term bronchiolitic infants, than control infants (P,0.025) but similar amounts of MPO. BAL neutrophils from bronchiolitic infants had increased amounts of CD11b and MPO than blood neutrophils and BAL neutrophils from controls (P,0.01). Blood neutrophils from term RSV infants had less total TLR4 protein than preterm RSV infants (P=0.005) and both had less than controls (P,0.04). Total TLR4 for each group was greater in ...
We demonstrate, for the first time to the best of our knowledge, an association between disease severity in children hospitalised with viral bronchiolitis and 1) IL-15 mRNA expression in PBMCs and 2) IL-15 concentration in serum. We identified the source of IL-15 in PBMCs as a subpopulation of DCs that are expanded in viral bronchiolitis, and also report a correlation between IL-15 levels and intracellular expression of antiapoptotic proteins Bcl-2 and Bcl-xL in lymphocytes of children with bronchiolitis. We identified a distinct pattern of NK cell miRNA expression in bronchiolitis and differential expression of a selection of their putative mRNA targets, among them genes for signalling molecules in the IL-15 pathway.. Children with viral bronchiolitis in our cohort demonstrated upregulation of IL-15 mRNA expression in PBMCs and increased serum levels of IL-15. This is consistent with an appropriate innate immune response to a viral infection, as it promotes activation and recruitment of NK ...
Recurrent cough and wheeze after bronchiolitis is reported in up to 70% of infants after the acute illness.2-7 Underlying airway abnormalities23 24 and/or a genetic predisposition have been implicated. The cause and effect of RSV infection on this chronic respiratory morbidity is not clear, but alteration of the IgE immune response to environmental allergens after bronchiolitis has been demonstrated.25 The acute inflammatory abnormalities within the airways of infants with acute bronchiolitis are similar to those seen in children with acute exacerbations of asthma.8 Therefore, it is possible that the administration of corticosteroids in the acute phase of the illness might have an effect on the natural history. A number of studies giving corticosteroids as a nebulised solution,10 11 13-15intramuscularly,16-18 and orally,12 19 20have examined this issue. Others have looked at the effects of steroid administration on the post-bronchiolitic symptoms.26 27Unfortunately, because of differing design, ...

Aim: To investigate the relationship between the polymorphism of CA microsatellite(rs3138557) in IFNgamma gene and theseverity to respiratory syncytial virus (RSV) infection.. Methods: The IFNgamma CA microsatellite was tested in 218 RSV bronchiolitis inpatients and 303 healthy children as control. The severity of RSV bronchiolitis was evaluated by standardized respiratory scoring system. Results: (1) The frequencies of CA12+/CA12+, CA12+/CA12- and CA12-/CA12- in the RSV bronchiolitis group were11%, 55.05% and35.95% respectively. The frequencies in the control group were19.47%, 52.81% and 27.72% respectively. The gene polymorphism of IFN gamma CA repeats between both groups was statistically different (P = 0.024).. (2) The clinical respiratory scores of RSV bronchiolitis cases with CA12+/CA12+, CA12+/CA12- were 2.84 plusmn 0.41; 2.95plusmn0.44 respectively. These scores were lower than those with CA12-/CA12- (3.10plusmn0.36).(P=0.004; P=0.027).. Conclusion: The polymorphism of IFN gamma CA ...
Patients baseline characteristics were similar between the two periods. P2 is associated with a significant decrease in the length of ventilation (LOV) (4.1 ± 3.5 versus 6.9 ± 4.6 days, p , 0.001), PICU length of stay (LOS) (6.2 ± 4.6 versus 9.7 ± 5.5 days, p , 0.001) and hospital LOS. nCPAP was independently associated with a shorter duration of ventilatory support than MV (hazard ratio 1.8, 95 % CI 1.5-2.2, p , 0.001). nCPAP was also associated with a significant decrease in ventilation-associated complications, and less invasive management. The mean cost of acute viral bronchiolitis-related PICU hospitalizations was significantly decreased, from 17,451 to 11,205 € (p , 0.001). Implementation of nCPAP led to a reduction of the total annual cost of acute viral bronchiolitis hospitalizations of 715,000 €.. ...
Any Pediatric Coders/CDI want to help me with this one. It is RSV Bronchiolitis season at our hospital and we have a question about the kids who come
BACKGROUND: Experimental and clinical evidence suggests that respiratory syncytial virus (RSV) bronchiolitis is an immune mediated disease. Corticosteroids might therefore be effective in the treatment of RSV bronchiolitis. METHODS: A randomised double blind trial was conducted in children up to two years of age admitted to hospital with RSV bronchiolitis to compare prednisolone (1 mg/ kg/day orally for seven days) with placebo. Variables used for the efficacy analysis were a daily symptom score and the length of time in hospital in the non-ventilated patients, and the duration of mechanical ventilation and the length of time in hospital in the ventilated patients. RESULTS: Fifty four patients were included in the trial, 40 of whom were non-ventilated (20 in each group) and 14 were ventilated (seven in each group). During the first three days of treatment the symptom score decreased significantly faster in the prednisolone group than in the placebo group (mean (SE) decrease -1.2 (0.2) points/day ...

Respiratory syncytial virus (RSV) is the most common cause of serious viral bronchiolitis in infants, young children, and the elderly. Currently, there is not an FDA-approved vaccine available for RSV, though the mAb palivizumab is licensed to reduce the incidence of RSV disease in premature or at-risk infants. The palivizumab epitope is a well-characterized, approximately 24-aa helix-loop-helix structure on the RSV fusion (F) protein (F254-277). Here, we genetically inserted this epitope and multiple site variants of this epitope within a versatile woodchuck hepadnavirus core-based virus-like particle (WHcAg-VLP) to generate hybrid VLPs that each bears 240 copies of the RSV epitope in a highly immunogenic arrayed format. A challenge of such an epitope-focused approach is that to be effective, the conformational F254-277 epitope must elicit antibodies that recognize the intact virus. A number of hybrid VLPs containing RSV F254-277 were recognized by palivizumab in vitro and elicited high-titer ...
Jürgen Schwarzes group studies immune mechanisms of viral bronchiolitis and the role of virus induced immune modulation in allergy and asthma focusing on the innate/adaptive immune interface in the lung.
Boy we have gone through a rough few months! I dont want to go into too much detail, but it has been hard. So just when I get healed up from my c-section, I had to get my gallbladder removed a few weeks ago. That was brutal! Thank goodness my Grandma came up and stayed with us. She is amazing! She took care of the kiddos for me and made dinner and cleaned and everything! I dont know what I would have done if she hadnt been there. Then Quincy came down with a really high fever and with her history we have to get her treated right away. Two instacare visits and a night spent in the ER, a fever of 104.9 at one point, and two medication changes, they finally got her better. The worst part was that Deacon ended up getting very sick and had to be put in the hospital. He had viral bronchiolitis and had to be hooked up to all these monitors and machines and IVs and get his lungs suctioned out and be given medications so that he could breathe. It was so sad! They even had to take blood from out of his ...
Since Ive been on here... My little chunk is a solid 14pounds :-) and she was born a tiny 5.12! But on a more serious note she has bronchiolitis and does breathing treatment every four hours. Now my question is, for you ladies who have/had kids who had rsv/bronchiolitis, how long did it take baby to get over it?! Lo sounds terrible!
It may be possible for a child with a high risk of developing severe bronchiolitis to have monthly antibody injections during the winter (November to March). The injections may help to limit the severity of the condition if the child becomes infected. Children who may be considered to be at high risk include those:. ...
BACKGROUND: Airway oedema (swelling) and mucus plugging are the principal pathological features in infants with acute viral bronchiolitis. Nebulised hypertonic saline solution (≥ 3%) may reduce these pathological changes and decrease airway obstruction. This is an update of a review first published in 2008, and previously updated in 2010 and 2013. OBJECTIVES: To assess the effects of nebulised hypertonic (≥ 3%) saline solution in infants with acute bronchiolitis. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily, Embase, CINAHL, LILACS, and Web of Science on 11 August 2017. We also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov on 8 April 2017. SELECTION CRITERIA: We included randomised controlled trials and quasi-randomised controlled trials using nebulised hypertonic saline alone ...
Aim: Infants with viral bronchiolitis are often hospitalised with a proportion requiring respiratory support. The aim of this review was to examine the use of nasal prong continuous positive airway pressure (CPAP) as a management strategy for infants with a diagnosis of bronchiolitis, who required stabilisation and transport to a tertiary centre.. Method: A retrospective audit of infants with bronchiolitis requiring CPAP during transport between January 2003 and June 2007.. Results: Nasal CPAP was initiated in 54 infants with 51 of these (34 ex-preterm, 17 term) subsequently continuing on CPAP during retrieval. Mean CPAP pressure was 7 cmH2O. Oxygenation improved between stabilisation and the end of retrieval (P , 0.01). During retrieval, there was no significant increase in transcutaneous CO2, no infant required endotracheal ventilation and no adverse events were noted. Five infants were intubated within the first 24 h of admission at the receiving hospital.. Conclusion: This review ...
In our study we found eight clinical predictors of admission in infants with acute bronchiolitis. We also developed a clinical risk scoring system which can be used in the emergency department to aid clinical decision making. This scoring system is simple and easy to use, making it applicable to a busy clinical setting. It was developed in a large number of children who were consecutively recruited using a retrospective sample which eliminated any potential observer bias. It employs only objective clinical parameters, limiting the potential for variability when used by different clinicians. The scoring system was developed with clinical applicability as a priority rather than the maximisation of statistical accuracy.. While other studies have looked at predictors of admission in children with bronchiolitis, no other studies have only included infants in their study population. Although in some countries bronchiolitis is diagnosed up to the age of five, a large majority of those admitted to ...
Acute bronchiolitis refers to airway inflammation and obstruction of the lower respiratory tract and is caused almost exclusively by viral infection in children younger than 2 years. Commonly, symptoms of bronchiolitis begin with rhinitis or congestion and cough and may develop into symptoms of increasing respiratory distress (tachypnea, wheezing, and accessory muscle use). (1) Severity of bronchiolitis can vary from mild symptoms that can be managed at home to acute respiratory failure requiring invasive ventilation. There is wide variation in care for infants admitted to the hospital with bronchiolitis, which persists despite the existence of guidelines. (2)(3)(4) In 2014, the American Academy of Pediatrics (AAP) published the Clinical Practice Guideline: The Diagnosis, Management, and Prevention of Bronchiolitis (1) (summarized in Table 1), an updated, revised version of a previous 2006 AAP guideline. (5) The strength of these recommendations are explained in Table 2. (1 … ...
I dont remember exactly when I started speaking in medical terms, it just sort of happened. I used to define Evey and Bens illnesses in normal every day terms. Fast heart beat. Barky cough. Old man cough - I really did say that once when Ben was wheezing really bad because I didnt know how else to describe it. Now terms like sinus rhythm, tachycardia, bronchiolitis, chronic lung disease are part of my every day vocabulary and I am frequently asked by health care professionals if Im a nurse. Nope. Just a mom.. So Im digressing. Bens chest x-ray was negative yesterday. AWESOME. Ben has non-RSV bronchiolitis. Again. Not awesome. Non RSV bronchiolitis - what is it? Its essentially RSV without the actual RSV virus. So what is that? Its swelling of the teeny tiny airways in his lungs and is caused by a virus that infects the lower part of his lungs. It causes a nasty cough, shortness of breath, a runny nose, and wheezing, really bad wheezing. Most kids dont get this unless they fall into a ...
If like me, I never even knew that Bronchiolitis could kill a child? she wrote.. You here[sic] about meningitis, measles, mumps and rubella all being serious childhood illnesses but no body tells you about Bronchiolitis and after speaking with other parents and doctors it is more common than I ever realised especially at this time of year.. Bronchiolitis is an infection of the lungs that causes an inflammation in the bronchioles, the smallest airways that carry oxygen to the lungs.. The ailment is often the result of a virus, and usually develops during the winter months. Symptoms can include:. -Runny nose. -Stuffy nose. -Cough. -Slight fever (but not always). -Wheezing. -Difficulty breathing. -An ear infection in some infants. There is no cure for bronchiolitis, but it usually goes away of its own accord within a few weeks, according to the Mayo Clinic.. Its not clear why sepsis occurs, but it happens when the immune system stops fighting an infection and starts attacking the body instead. ...
Bronchiolitis is a common cause of pediatric hospitalization. Variation in the use of tests and treatments for management of bronchiolitis exists, some of which may contribute to increased health care costs that are estimated to be $545 million annual total direct expenditure nationally.1 In 2006, the American Academy of Pediatrics published a national clinical practice guideline (CPG) for management of children with bronchiolitis.2 The CPG does not recommend routine tests and treatments, emphasizing a diagnosis of bronchiolitis based on history and physical examination, and supportive management. Nevertheless, nationally, there is a wide variation in use of tests and treatments in the management of bronchiolitis.2-4. CPGs can be a powerful resource to reduce variation and help providers deliver disease-specific best practice.5,6 Therefore, many national organizations support development of CPGs.7-9 Integrating a CPG into practice requires changes in physician behaviors and remains a significant ...
The following was adapted from the Canadian Pediatric Societys statement on Bronchiolitis: Recommendations for diagnosis, monitoring and management of children one to 24 months of age. Please see the full statement for the full recommendations from the Canadian Pediatric Society.. Background:. Bronchiolitis is a viral lower respiratory tract infection that leads to obstruction of the small airways. Respiratory syncytial virus (RSV) is responsible for most cases, however other viruses can cause a similar clinical picture. In Canada, RSV season usually begins between November and January and persists for four to five months. Bronchiolitis affects more than one third of children in the first two years of life and is the most common cause of admission to hospital in the first year. Despite being so common, there is great variation in standards for diagnosis and management of bronchiolitis, which you may see in clinical practice. These guidelines incorporate the most recent evidence to provide ...
Background: Bronchiolitis is a serious, potentially life-threatening respiratory illness commonly affecting babies. It is often caused by respiratory syncytial virus (RSV). Antibiotics are not recommended for bronchiolitis unless there is concern about complications such as secondary bacterial pneumonia or respiratory failure. Nevertheless, they are used at rates of 34% to 99% in uncomplicated cases. Objectives: To evaluate the effectiveness of antibiotics for bronchiolitis. Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2010, issue 4), which includes the Cochrane Acute Respiratory Infection Groups Specialised Register, and the Database of Abstracts of Reviews of Effects, MEDLINE (January 1966 to November 2010), EMBASE (1990 to December 2010) and Current Contents (2001 to December 2010). Selection criteria: Randomised controlled trials (RCTs) comparing antibiotics to placebo in children under two years diagnosed with bronchiolitis, using clinical criteria
In England last year, nearly 40,000 babies and young children with bronchiolitis were admitted to hospital. This infection is usually caused by the respiratory syncytial virus, and in most cases symptoms are mild and last only a few days.. However, a quality standard published in the summer by the National Institute for Health and Care Excellence (NICE) states that admissions for bronchiolitis are rising. NICE quality standards describe high-priority areas for improvement in a defined field of care.. Bronchiolitis is now the third most common reason why babies and young children are admitted to hospital, the quality standard states. But the treatment given is not always in line with recommendations.. Antibiotics. The standard quotes from studies undertaken in UK hospitals that show children with bronchiolitis are being given antibiotics even though these are often ineffective and have side effects. Reducing unnecessary antibiotics will prevent the development of bacterial resistance and will ...
Bronchiolitis is a distressing respiratory condition and the most common cause of hospitalization during the first year of life. The hospitalization of an infant is a stressful event for parents and deserves careful consideration. The objective of this work was to develop and validate a self-administered instrument that comprehensively assesses the impact on parents of the hospitalization of their infant for bronchiolitis. The Impact of Bronchiolitis Hospitalization Questionnaire (IBHQ©) was developed using a literature review and pre-study interviews with both parents and clinicians. For finalization and psychometric validation, it was included in a multicenter, longitudinal, observational study conducted in France. Parents of infants under the age of 1 year and hospitalized for bronchiolitis were asked to complete the questionnaire at hospital discharge, and 3 months after. Seven hundred and seven questionnaires were completed by the parents of the 463 eligible infants. After finalization, based on
The results of the current study reveal a low incidence of SBI in children hospitalized with bronchiolitis. The only SBI we identified was UTI (2.3% of patients). There were no cases of bacteremia or meningitis. Due to the fact our study was designed to evaluate provider practices and excluded patients admitted to the PICU, the incidence of SBI reported in this article may not be a true reflection of the overall incidence of SBI in patients with bronchiolitis. Nevertheless, our findings are similar to previous studies that have shown a low incidence of concurrent SBI in patients with bronchiolitis.3-14 A recent literature review reported on occult SBI in young infants with bronchiolitis.11 In the review of 11 included studies, the weighted rate of UTI was 3.3% (95% confidence interval: 1.9-5.7). There were no cases of bacteremia in 8 of the 11 studies and no cases of meningitis in any of the studies. This evidence further supports our findings of the potential low yield of SBI testing in ...
During the 2000-2001 RSV season, we approved 212 requests for palivizumab. 12 of these members, 5.7 percent, required hospitalization for proven RSV lower respiratory tract disease, either RSV bronchiolitis (ICD-9 code 466.11) or RSV pneumonia (ICD-9 code 480.1). The average length of stay was 4.6 days. These results are consistent with the results of the original randomized clinical trial of palivizumab. In that study, known as the Impact-RSV trial, there was a 55-percent overall reduction in RSV-related hospitalizations (11 percent compared to 5 percent in placebo vs. palivizumab recipients).2. Nevertheless, the big question is: What about the requests that were denied? What about the patients who were between 32 and 35 weeks gestation whose only risk factors were the additional risk factors listed in the accompanying table? In the American Academy of Pediatrics Committee on Infectious Diseases and Committee on Fetus and the Newborn article on RSV infections and indications for the use of ...
Since these respiratory viruses, especially RSV, produce so much illness in young children and are a major cause of medical visits and costs, much research currently is underway. This research is focused on developing effective vaccines to prevent RSV and to prevent infection with some of the other respiratory viruses, such as the parainfluenza and influenza viruses. Although a number of vaccines for the prevention of RSV have been tested in clinical trials, they have yet to be approved for general use. A number of vaccines, which contain live, but weakened, or inactive parts of the virus, appear promising and are being tested further. In addition, a number of antiviral drugs are being developed and tested for both preventing and treating the viruses that cause bronchiolitis.. top. References.

The findings of this prospective study contribute to the debate that is ongoing about RSV/non-RSV bronchiolitis at infancy as an asthma predictive factor. This study contributes new data to the debate on bronchiolitis admissions at age ,6 months. However, the reported rate of asthma in the follow-up group was notably lower than what has been reported in previous research. Future research should focus on investigating further the mechanisms of viral etiology in bronchiolitis and whether it can contribute to early-life risk factors for developing asthma. ...

This study provides an evaluation of chest physiotherapy with IET + AC in a large population of infants hospitalized for a first episode of bronchiolitis with time to recovery as the primary endpoint. In this seven-center trial, no evidence of any difference in time to recovery between the IET + AC group and the NS group was found, with no interaction with age group. The CIs around estimates of effect excluded a clinically meaningful difference in time to recovery between groups in the whole population.. Otherwise, there was no evidence of any difference in secondary outcomes between children with and without IET + AC except for vomiting and transient respiratory destabilization during the procedure. This significant difference of vomiting and respiratory destabilization frequency was expected and in accordance with our physiotherapistsexperiences. However, it is worth noting that these side effects of IET + AC were transient and resolved as soon as the procedure was interrupted. Although not ...
These RCTs were well designed, with low overall risk of bias, albeit with some imperfections. Wu and colleagues study was underpowered to detect a planned difference of 30% in admission rate or 24 h in LOS. There was no objective severity of illness criteria for inclusion, admission or discharge readiness, making clinician bias a potential issue. Florin and colleagues included a wide severity-of-illness range (Respiratory Distress Assessment Index (RDAI)4-15) and utilised the RACS (calculated using change in RDAI and respiratory rate), as short-term proxy outcome for need for hospitalisation. Their study was not powered for detection of a change in admission rate.. The RDAI has poor discriminative and construct validity in predicting hospitalisation and LOS in bronchiolitis, in part because it does not include respiratory rate or O2 saturation, both important variables for a clinician to determine disposition.3 Wu and colleagues reaffirm this limitation-although they reported no significant ...

Understanding why some children develop severe bronchiolitis while most children experience an upper respiratory tract infection upon RSV infection remains essential and needs to be answered to improve the care of RSV-infected children in the future. Where several previous studies focused on the microbial content involved in bronchiolitis, most notably by Hasegawa and coworkers, our study exclusively focused on RSV-implicated bronchiolitis [29, 30]. RSV disease severity is a multifactorial problem, in which the viral load and the inflammatory response are important drivers of disease, although this is mainly true in previously healthy children whose airways are normal [6, 7, 12]. An important question this study tried to answer is whether nasopharyngeal microbiome composition relates to local viral load and exerts an influence on mucosal immune responses. Viral load and mucosal immune responses are thought to directly impact disease severity, and therefore, it is difficult to disentangle these ...

Bronchiolitis is a condition that can make infants alarmingly ill and breathless, and it tends to recur each time a child gets an upper respiratory virus in the first two years of life. When faced with a wheezy sounding baby or toddler breathing 60 times a minute, many doctors cannot resist the temptation to try a β adrenergic inhaler. But resist they should. The latest Cochrane review of bronchodilators for bronchiolitis concludes: Bronchodilators such as albuterol or salbutamol do not improve oxygen saturation, do not reduce hospital admission after outpatient treatment, do not shorten the duration of hospitalization and do not reduce the time to resolution of illness at home. (Cochrane Database of Systematic Reviews 2014;6:CD001266.)​ ...

When compared to children with each CC of TLR4 polymorphism or TT of CD14 polymorphism or GG of IL13 polymorphism and no past history of bronchiolitis, children with CT or TT of TLR4 polymorphism and past history of bronchiolitis had 4.23 and 5.34 times higher risk to develop asthma, respectively; children with TT of CD14 polymorphism and past history of bronchiolitis had 3.57 and 7.22 times higher risk for asthma, respectively; children with GA or AA of IL-13 polymorphism and past history of bronchiolitis had 3.21 and 4.13 times higher risk for asthma, respectively. ...
There may be a link between bronchiolitis and developing respiratory conditions such as asthma in later life. However, the link isnt fully understood. Its not clear whether having bronchiolitis as an infant increases your risk of developing asthma later in life, or whether there are environmental or genetic (inherited) factors that cause both bronchiolitis and asthma. If your child has repeated bouts of bronchiolitis, their risk of developing asthma later in life may be increased. ...

Bronchiolitis is an acute inflammatory injury of the bronchioles that is usually caused by a viral infection. Although it may occur in persons of any age, severe symptoms are usually only evident in young infants; the larger airways of older children and adults better accommodate mucosal edema.
Bronchiolitis typically affects infants and children under 2 years old[1] but it can also affect people of any age. It also has a seasonal predilection, with more infections during the winter.[1]
Following publication earlier this year of NICE guidance on the diagnosis and management of bronchiolitis, the authors consider the implications, treatment
Hep-2 cells (ATCC CCL-23) may be used to propagate the human respiratory syncitial virus (ATCC VR-1540) that causes bronchiolitis
Bronchiolitis is a common type of chest infection so its best to know about it. Here we talk about its symptoms, treatment and how to prevent it.
Since these respiratory viruses, especially RSV, produce so much illness in young children and are a major cause of medical visits and costs, much research currently is underway. This research is focused on developing effective vaccines to prevent RSV and to prevent infection with some of the other respiratory viruses, such as the parainfluenza and influenza viruses. Although a number of vaccines for the prevention of RSV have been tested in clinical trials, they have yet to be approved for general use. A number of vaccines, which contain live, but weakened, or inactive parts of the virus, appear promising and are being tested further. In addition, a number of antiviral drugs are being developed and tested for both preventing and treating the viruses that cause bronchiolitis. top.
