PURPOSE
Acute cough due to viral upper respiratory tract infections (URTIs) and bronchitis is a common reason for patients to seek medical care. Non-antibiotic over-the-counter cough medications such as ivy leaf extract are frequently used but their efficacy is uncertain. Our purpose was to update our previous systematic review and evaluate the effectiveness and tolerability of ivy leaf in the treatment of acute URTIs in adult and pediatric populations.
METHODS
We searched MEDLINE, EMBASE, the Cochrane Library, and clinical trial registries from December 2009 to January 2020. Randomized controlled trials (RCTs), controlled clinical trials (CCTs), and observational studies (OSs) investigating ivy leaf mono- or combination preparations were included. Two independent reviewers assessed records for eligibility and risk of bias and performed data extraction.
RESULTS
Six RCTs, 1 CCT, and 4 OSs were identified. Since the publication of our previous review, the number of RCTs has increased. All studies concluded that ivy leaf extract is an effective and safe option for the treatment of cough due to URTIs and bronchitis. Three RCTs reported a more rapid reduction in cough severity and/or frequency under ivy leaf treatment. The clinical significance of these effects appears to be minimal. No serious adverse effects were reported. The overall quality of reporting was low and the risk of bias was high.
CONCLUSIONS
Ivy leaf preparations are safe for use in cough due to acute URTIs and bronchitis. However, effects are minimal at best and of uncertain clinical importance.

Review
INTRODUCTION
Acute bronchitis affects over 40/1000 adults a year in the UK. The causes are usually considered to be infective, but only around half of people have identifiable pathogens. The role of smoking or of environmental tobacco smoke inhalation in predisposing to acute bronchitis is unclear. One third of people may have longer-term symptoms or recurrence.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute bronchitis in people without chronic respiratory disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 21 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: analgesics, antibiotics (macrolides, tetracyclines, cephalosporins, penicillins, or trimethoprim-sulfamethoxazole [co-trimoxazole]), antihistamines, antitussives, beta(2) agonists (inhaled or oral), and expectorants/mucolytics.

Review
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 updated in 2010, 2013, and 2017.
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 13 January 2022. We also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov on 13 January 2022.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) and quasi-RCTs using nebulised hypertonic saline alone or in conjunction with bronchodilators as an active intervention and nebulised 0.9% saline or standard treatment as a comparator in children under 24 months with acute bronchiolitis. The primary outcome for inpatient trials was length of hospital stay, and the primary outcome for outpatients or emergency department (ED) trials was rate of hospitalisation.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, data extraction, and assessment of risk of bias in included studies. We conducted random-effects model meta-analyses using Review Manager 5. We used mean difference (MD), risk ratio (RR), and their 95% confidence intervals (CI) as effect size metrics.
MAIN RESULTS
We included six new trials (N = 1010) in this update, bringing the total number of included trials to 34, involving 5205 infants with acute bronchiolitis, of whom 2727 infants received hypertonic saline. Eleven trials await classification due to insufficient data for eligibility assessment. All included trials were randomised, parallel-group, controlled trials, of which 30 were double-blinded. Twelve trials were conducted in Asia, five in North America, one in South America, seven in Europe, and nine in Mediterranean and Middle East regions. The concentration of hypertonic saline was defined as 3% in all but six trials, in which 5% to 7% saline was used. Nine trials had no funding, and five trials were funded by sources from government or academic agencies. The remaining 20 trials did not provide funding sources. Hospitalised infants treated with nebulised hypertonic saline may have a shorter mean length of hospital stay compared to those treated with nebulised normal (0.9%) saline or standard care (mean difference (MD) -0.40 days, 95% confidence interval (CI) -0.69 to -0.11; 21 trials, 2479 infants; low-certainty evidence). Infants who received hypertonic saline may also have lower postinhalation clinical scores than infants who received normal saline in the first three days of treatment (day 1: MD -0.64, 95% CI -1.08 to -0.21; 10 trials (1 outpatient, 1 ED, 8 inpatient trials), 893 infants; day 2: MD -1.07, 95% CI -1.60 to -0.53; 10 trials (1 outpatient, 1 ED, 8 inpatient trials), 907 infants; day 3: MD -0.89, 95% CI -1.44 to -0.34; 10 trials (1 outpatient, 9 inpatient trials), 785 infants; low-certainty evidence). Nebulised hypertonic saline may reduce the risk of hospitalisation by 13% compared with nebulised normal saline amongst infants who were outpatients and those treated in the ED (risk ratio (RR) 0.87, 95% CI 0.78 to 0.97; 8 trials, 1760 infants; low-certainty evidence). However, hypertonic saline may not reduce the risk of readmission to hospital up to 28 days after discharge (RR 0.83, 95% CI 0.55 to 1.25; 6 trials, 1084 infants; low-certainty evidence). We are uncertain whether infants who received hypertonic saline have a lower number of days to resolution of wheezing compared to those who received normal saline (MD -1.16 days, 95% CI -1.43 to -0.89; 2 trials, 205 infants; very low-certainty evidence), cough (MD -0.87 days, 95% CI -1.31 to -0.44; 3 trials, 363 infants; very low-certainty evidence), and pulmonary moist crackles (MD -1.30 days, 95% CI -2.28 to -0.32; 2 trials, 205 infants; very low-certainty evidence). Twenty-seven trials presented safety data: 14 trials (1624 infants; 767 treated with hypertonic saline, of which 735 (96%) co-administered with bronchodilators) did not report any adverse events, and 13 trials (2792 infants; 1479 treated with hypertonic saline, of which 416 (28%) co-administered with bronchodilators and 1063 (72%) hypertonic saline alone) reported at least one adverse event such as worsening cough, agitation, bronchospasm, bradycardia, desaturation, vomiting and diarrhoea, most of which were mild and resolved spontaneously (low-certainty evidence).
AUTHORS' CONCLUSIONS
Nebulised hypertonic saline may modestly reduce length of stay amongst infants hospitalised with acute bronchiolitis and may slightly improve clinical severity score. Treatment with nebulised hypertonic saline may also reduce the risk of hospitalisation amongst outpatients and ED patients. Nebulised hypertonic saline seems to be a safe treatment in infants with bronchiolitis with only minor and spontaneously resolved adverse events, especially when administered in conjunction with a bronchodilator. The certainty of the evidence was low to very low for all outcomes, mainly due to inconsistency and risk of bias.

Review
INTRODUCTION
Acute bronchitis, with transient inflammation of the trachea and major bronchi, affects over 40/1000 adults a year in the UK. The causes are usually considered to be infective, but only around half of people have identifiable pathogens. The role of smoking or of environmental tobacco smoke inhalation in predisposing to acute bronchitis is unclear. A third of people may have longer-term symptoms or recurrence.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute bronchitis in people without chronic respiratory disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (amoxicillin [with or without clavulanic acid], cephalosporins, or macrolides), antihistamines, antitussives, beta(2) agonists (inhaled or oral), cephalosporins, expectorants, and analgesics.

Complementary Therapies in Medicine Mar 2020Our review summarizes published literature of complementary and alternative medicine (CAM) used for the treatment of acute bronchitis in children.
OBJECTIVE
Our review summarizes published literature of complementary and alternative medicine (CAM) used for the treatment of acute bronchitis in children.
BACKGROUND
Acute bronchitis is one of the most frequent pediatric diseases and has high prevalence for in- and outpatient care. Acute bronchitis is mainly a viral-caused infection, but a high and inappropriate use of antibiotics has been demonstrated in many countries. As CAM therapies might reduce the use of antibiotics and can complement conventional therapies in children, they could be an appropriate treatment option.
METHODS
A systematic literature search was conducted using general and complementary and alternative medicine (CAM)-specific databases. A search term including 65 CAM-associated definitions was applied.
RESULTS
Literature search revealed 309 articles, whereby 18 articles hit search criteria. These clinical trials were subgrouped into the categories herbal medicine, anthroposophic medicine and homeopathy. The most often studied approaches are herbal remedies, in particular the Pelargonium sidoides extract, EPs® 7630. Its efficacy was demonstrated in three placebo-controlled trials and two observational studies. Anthroposophic approaches (mainly ribwort-containing remedies) were investigated in two controlled trials and three observational studies. Two studies were found investigating the homeopathic remedies Monapax® and Droperteel®.
CONCLUSION
Study results indicate a favorable effect of investigated CAM approaches. However, only three of 18 studies were randomized controlled trials (RCTs), so a reliable statement on effectiveness was not possible and further RCTs are indispensable.

Comparative Study Meta-Analysis
CONTEXT
Uncertainty exists as to which treatments are most effective for bronchiolitis, with considerable practice variation within and across health care sites.
OBJECTIVE
A network meta-analysis to compare the effectiveness of common treatments for bronchiolitis in children aged ≤2 years.
DATA SOURCES
Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform were searched from inception to September 1, 2019.
STUDY SELECTION
A total 150 randomized controlled trials comparing a placebo or active comparator with any bronchodilator, glucocorticoid steroid, hypertonic saline solution, antibiotic, helium-oxygen therapy, or high-flow oxygen therapy were included.
DATA EXTRACTION
Data were extracted by 1 reviewer and independently verified. Primary outcomes were admission rate on day 1 and by day 7 and hospital length of stay. Strength of evidence was assessed by using Confidence in Network Meta-Analysis .
RESULTS
Nebulized epinephrine (odds ratio: 0.64, 95% confidence interval [CI]: 0.44 to 0.93, low confidence) and nebulized hypertonic saline plus salbutamol (odds ratio: 0.44, 95% CI: 0.23 to 0.84, low confidence) reduced the admission rate on day 1. No treatment significantly reduced the admission rate on day 7. Nebulized hypertonic saline (mean difference: -0.64 days, 95% CI: -1.01 to -0.26, low confidence) and nebulized hypertonic saline plus epinephrine (mean difference: -0.91 days, 95% CI: -1.14 to -0.40, low confidence) reduced hospital length of stay.
LIMITATIONS
Because we did not report adverse events in this analysis, we cannot make inferences about the safety of these treatments.
CONCLUSIONS
Although hypertonic saline alone, or combined with epinephrine, may reduce an infant's stay in the hospital, poor strength of evidence necessitates additional rigorous trials.

Meta-Analysis
BACKGROUND
To assess the published evidence to establish the efficacy and safety of high flow oxygen cannula (HFNC) as respiratory support for children up to 24 months of age with bronchiolitis within acute hospital settings.
METHODS
We searched eight databases up to March 2021. Studies including children up to 24 months of age with a diagnosis of bronchiolitis recruited to an randomised controlled trial were considered in the full meta-analysis. At least one arm of the study must include HFNC as respiratory support and report at least one of the outcomes of interest. Studies were identified and extracted by two reviewers. Data were analysed using Review Manager V.5.4.
RESULTS
From 2943 article titles, 308 full articles were screened for inclusion. 23 studies met the inclusion criteria, 15 were included in the metanalyses. Four studies reported on treatment failure rates when comparing HFNC to standard oxygen therapy (SOT). Data suggests HFNC is superior to SOT (OR 0.45, 95% CI 0.36 to 0.57). Four studies reported on treatment failure rates when comparing HFNC to continuous positive airways pressure (CPAP). No significant difference was found between CPAP and HFNC (OR 1.64, 95% CI 0.96 to 2.79; p=0.07). Four studies report on adverse outcomes when comparing HFNC to SOT. No significant difference was found between HFNC & SOT (OR 1.47, 95% CI 0.54 to 3.99).
CONCLUSION
HFNC is superior to SOT in terms of treatment failure and there is no significant difference between HFNC and CPAP in terms of treatment failure. The results suggest HFNC is safe to use in acute hospital settings.

Review
AIM
Lung ultrasound (LUS) has not been included in the current guidelines for the diagnosis of bronchiolitis so far, even though data concerning its effectiveness have been published.
METHODS
A systematic literature review was carried out to determine the role of LUS scores in the diagnosis and prognosis of patients aged 0-2 years with bronchiolitis, using MEDLINE, Scopus and ScienceDirect databases from their inception to December 2021.
RESULTS
A total of 18 studies matching our eligibility criteria were analysed for the purposes of this review and 1249 patients with bronchiolitis were included. The sonographic and radiological findings were comparable and chest radiography was found to have a higher sensitivity in ruling out severe complications such as concomitant pneumonia. The LUS scores were correlated to the clinical course of bronchiolitis and it was able to predict the need of admission in paediatric intensive care unit, the duration of hospitalisation and the need for respiratory support.
CONCLUSION
This review suggests that LUS could have both a diagnostic and a prognostic role in bronchiolitis during first evaluation in the emergency department and hospitalisation. Physicians could adjust management according to sonographic findings as a useful adjunct to the clinical ones.

Review
INTRODUCTION
Bronchiolitis is the most common lower respiratory tract infection in infants, occurring in a seasonal pattern, with highest incidence in the winter in temperate climates and in the rainy season in warmer countries. Bronchiolitis is a common reason for attendance at and admission to hospital.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of prophylactic interventions for bronchiolitis in high-risk children? What are the effects of measures to prevent transmission of bronchiolitis in hospital? What are the effects of treatments for children with bronchiolitis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to July 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 59 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, bronchodilators (oral, inhaled salbutamol, inhaled adrenaline [epinephrine], hypertonic saline), chest physiotherapy, continuous positive airway pressure, corticosteroids, fluid management, heliox, montelukast, nasal decongestants, nursing interventions (cohort segregation, hand washing, gowns, masks, gloves, and goggles), oxygen, respiratory syncytial virus immunoglobulins, pooled immunoglobulins, or palivizumab (monoclonal antibody), ribavirin, or surfactants.

Meta-Analysis
BACKGROUND
In February, 2017, the US Food and Drug Administration approved the blood infection marker procalcitonin for guiding antibiotic therapy in patients with acute respiratory infections. This meta-analysis of patient data from 26 randomised controlled trials was designed to assess safety of procalcitonin-guided treatment in patients with acute respiratory infections from different clinical settings.
METHODS
Based on a prespecified Cochrane protocol, we did a systematic literature search on the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase, and pooled individual patient data from trials in which patients with respiratory infections were randomly assigned to receive antibiotics based on procalcitonin concentrations (procalcitonin-guided group) or control. The coprimary endpoints were 30-day mortality and setting-specific treatment failure. Secondary endpoints were antibiotic use, length of stay, and antibiotic side-effects.
FINDINGS
We identified 990 records from the literature search, of which 71 articles were assessed for eligibility after exclusion of 919 records. We collected data on 6708 patients from 26 eligible trials in 12 countries. Mortality at 30 days was significantly lower in procalcitonin-guided patients than in control patients (286 [9%] deaths in 3336 procalcitonin-guided patients vs 336 [10%] in 3372 controls; adjusted odds ratio [OR] 0·83 [95% CI 0·70 to 0·99], p=0·037). This mortality benefit was similar across subgroups by setting and type of infection (p>0·05), although mortality was very low in primary care and in patients with acute bronchitis. Procalcitonin guidance was also associated with a 2·4-day reduction in antibiotic exposure (5·7 vs 8·1 days [95% CI -2·71 to -2·15], p<0·0001) and a reduction in antibiotic-related side-effects (16% vs 22%, adjusted OR 0·68 [95% CI 0·57 to 0·82], p<0·0001).
INTERPRETATION
Use of procalcitonin to guide antibiotic treatment in patients with acute respiratory infections reduces antibiotic exposure and side-effects, and improves survival. Widespread implementation of procalcitonin protocols in patients with acute respiratory infections thus has the potential to improve antibiotic management with positive effects on clinical outcomes and on the current threat of increasing antibiotic multiresistance.
