Complementary and alternative medicine for the treatment of bronchiolitis in infants: A systematic review

Neutrophil-to-Lymphocyte Ratio and the Systemic Immune-Inflammation Index: Biomarkers in Infants with Bronchiolitis: a Cross-Sectional Study

The use of a novel inflammatory indicator, the systemic immune-inflammatory index (SII), in pediatric patients with bronchiolitis remains unreported. Therefore, this study investigated the relationship between the SII and the neutrophil-to-lymphocyte ratio (NLR) in patients with respiratory syncytial virus (RSV) and non-RSV bronchiolitis and clinical severity prediction. This study analyzed the data of 155 patients aged <2 years who were hospitalized for viral bronchiolitis caused by RSV and/or other viral pathogens. The SII (platelet count × [neutrophil/lymphocyte]) was calculated and compared among patients with RSV mono-infections, other viral mono-infections, and RSV co-infections. Severity was defined by the number of days of supplemental oxygen treatment. The NLR and SII were significantly higher in the non-RSV mono-infection group than in the RSV mono-infection group, and the number of days of supplemental oxygen therapy was significantly higher in the RSV mono-infection group. No significant differences in the NLR, SII, or days of supplemental oxygen therapy were found between the RSV mono-infection and RSV co-infection groups. Although patients with RSV mono-infection showed more severe clinical findings than those without non-RSV mono-infection, the NLR and SII values were significantly higher in the non-RSV mono-infection group. Therefore, the NLR and SII do not appear to be very useful measurements for determining the severity of acute bronchiolitis attacks; however, lower NLR and SII values in the RSV group compared to the non-RSV group may be potential biomarkers for RSV infection. Therefore, further studies are warranted.

Cultural adaptation of the Pan-Canadian Oncology Symptom triage and remote support practice guide for cancer-related fatigue in China: Integration of traditional Chinese medicine nursing evidence

Objective

This study aimed at culturally adapting pan-Canadian Oncology Symptom Triage and Remote Support (COSTaRS) Cancer-related fatigue (CRF) Practice Guide to enable its use in China. This article focuses on presenting the key cultural adaptation step: supplementing traditional Chinese medicine (TCM) nursing recommendations for CRF symptom management according to evidence.

Methods

Guided by A Guideline Adaptation and Implementation Planning Resource (CAN-IMPLEMENT), the process for cultural adaptation of the CRF guide in the COSTaRS project included translation, expert committee review, acceptability and feasibility assessment, and targeted adaptation to include TCM nursing techniques for CRF management via the Delphi method.

Results

First, an expert committee of nurses, nurse leaders, and researchers was established. The practice guide was translated and verified by the members of the expert committee. Nurses then rated the practice guide for acceptability and feasibility. Concurrently, 83 stakeholders (nurses and patients) identified five relevant TCM nursing techniques: acupuncture, moxibustion, acupressure therapy, Taijiquan, and auricular acupoint embedding. A systematic review of literature identified three clinical practice guidelines and four systematic reviews. Through two rounds of Delphi expert consultation, five TCM care strategies were added into the culturally adapted COSTaRS practice guide.

Conclusions

Cultural adaptation of the Canadian CRF practice guide involved not only language translation but also the addition of relevant TCM evidence. Combining TCM evidence and the Delphi method was a novel aspect of the cultural adaptation process. Further research is needed to investigate the implementation of the guide in appropriate settings in China.

Respiratory Syncytial Virus is the Most Common Causative Agent of Viral Bronchiolitis in Young Children: An Updated Review

BACKGROUND

Viral bronchiolitis is a common condition and a leading cause of hospitalization in young children.

OBJECTIVE

This article provides readers with an update on the evaluation, diagnosis, and treatment of viral bronchiolitis, primarily due to RSV.

METHODS

A PubMed search was conducted in December 2021 in Clinical Queries using the key terms "acute bronchiolitis" OR "respiratory syncytial virus infection". The search included clinical trials, randomized controlled trials, case control studies, cohort studies, meta-analyses, observational studies, clinical guidelines, case reports, case series, and reviews. The search was restricted to children and English literature. The information retrieved from the above search was used in the compilation of this article.

RESULTS

Respiratory syncytial virus (RSV) is the most common viral bronchiolitis in young children. Other viruses such as human rhinovirus and coronavirus could be etiological agents. Diagnosis is based on clinical manifestation. Viral testing is useful only for cohort and quarantine purposes. Cochrane evidence-based reviews have been performed on most treatment modalities for RSV and viral bronchiolitis. Treatment for viral bronchiolitis is mainly symptomatic support. Beta-agonists are frequently used despite the lack of evidence that they reduce hospital admissions or length of stay. Nebulized racemic epinephrine, hypertonic saline and corticosteroids are generally not effective. Passive immunoprophylaxis with a monoclonal antibody against RSV, when given intramuscularly and monthly during winter, is effective in preventing severe RSV bronchiolitis in high-risk children who are born prematurely and in children under 2 years with chronic lung disease or hemodynamically significant congenital heart disease. Vaccines for RSV bronchiolitis are being developed. Children with viral bronchiolitis in early life are at increased risk of developing asthma later in childhood.

CONCLUSION

Viral bronchiolitis is common. No current pharmacologic treatment or novel therapy has been proven to improve outcomes compared to supportive treatment. Viral bronchiolitis in early life predisposes asthma development later in childhood.

Using herbs medically without knowing their composition: are we playing Russian roulette?

Herbal medicine, a form of complementary and alternative medicine (CAM), is used throughout the world, in both developing and developed countries. The ingredients in herbal medicines are not standardized by any regulatory agency. Variability exists in the ingredients as well as in their concentrations. Plant products may become contaminated with bacteria and fungi during storage. Therefore, harm can occur to the kidney, liver, and blood components after ingestion. We encourage scientific studies to identify the active ingredients in herbs and to standardize their concentrations in all herbal preparations. Rigorous studies need to be performed in order to understand the effect of herbal ingredients on different organ systems as well as these substances' interaction with other medications.

Impact of COVID-19 outbreak in acute bronchiolitis: Lesson from a tertiary Italian Emergency Department

AIM

To assess the impact of the coronavirus disease 2019 (COVID-19) outbreak on pediatric emergency department (ED) visits for acute bronchiolitis during the epidemic season.

METHODS

A retrospective analytical cross-sectional study was performed in our hospital, analyzing medical charts of all children under 2 years of age with a diagnosis of acute bronchiolitis admitted to our ED in the last years. Demographics and clinical data of patients affected with acute bronchiolitis during the 2020-2021 season-COVID-19 outbreak-were compared to those of the 5 previous years.

RESULTS

We observed an average drop of 84% of the rate of acute bronchiolitis managed by pediatricians in ED in 2020-2021 compared with bronchiolitis seasons of 5 previous years. We also reported, during the COVID-19 outbreak, a higher number of children affected by acute bronchiolitis referred to ED as Emergency Consultations who required hospitalization. Regarding etiological agents, no differences in respiratory virus circulation, especially RSV, were observed in the two groups. The multivariate analysis showed no correlation between the diagnosis of RSV bronchiolitis and COVID-19 period or prematurity; lower age was associated with an increased likelihood of exhibiting RSV bronchiolitis (odds ratio 0.9; 95% confidence interval 0.86-0.95 p < .01).

CONCLUSION

Our data emphasize the reduction in the rate of admission to pediatric ED for acute bronchiolitis during the COVID-19 outbreak, regardless of changes in circulating respiratory viruses. Therefore we want to highlight the importance of nonpharmacological preventive hygiene measures that should be maintained even at the end of the COVID-19 outbreak.

Expert consensus-based clinical recommendation for an integrative anthroposophic treatment of acute bronchitis in children: A Delphi survey

BACKGROUND

Acute bronchitis is one of the most common pediatric diseases. In addition to conventional therapies, a frequent use of complementary and alternative medicine (CAM) has been stated. Anthroposophic medicine (AM) is one of the most practiced complementary and integrative medicine (CIM) approaches in Central Europe but hitherto no consensus-based clinical recommendations or guidelines are available. Therefore, a consensus-based recommendation leading to an informed and reasonable use of AM in the treatment of acute bronchitis in pediatrics was developed.

METHODS

A total of 61 physicians in Germany with expertise in the field of anthroposophic pediatrics was invited to complete an online multistep Delphi process. Two independent reviewers quantitatively and qualitatively evaluated the results. The survey was completed when >75 % consensus was achieved.

RESULTS

The clinical recommendation comprises 15 subitems related to treatment as well as clinical and psychosocial aspects. All items reached strong consensus (>90 %; N = 9) or consensus (75-90 %; N = 6).

CONCLUSION

The comprehensive clinical recommendation creates a scientific base for the anthroposophic integrative treatment of acute bronchitis in children in Germany. It will make the anthroposophic approach more applicable, understandable and comparable to a wider public of physicians and other health professionals in Germany.

Etiology, clinical characteristics and coinfection status of bronchiolitis in Suzhou

Background

Bronchiolitis is a clinical syndrome commonly encountered in practice, particularly among infants and young children. To investigate the prevalence of pathogens in hospitalized children with bronchiolitis and study the clinical characteristics of bronchiolitis with or without coinfections.

Methods

We investigated the respiratory specimens and clinical data of 1012 children with bronchiolitis who were treated at the Children’s Hospital of Soochow University between November 2011 and December 2018. The nasopharyngeal aspirates were examined to detect viruses by direct immunofluorescence assay or polymerase chain reaction (PCR). Mycoplasma pneumoniae (MP) was tested by PCR and enzyme-linked immunosorbent assay.

Results

Of the 1134 children less than 2 years with bronchiolitis, 122 were excluded by exclusion criteria. Causative pathogen was detected in 83.2% (842 of 1012). The majority of these (614 [72.9%] of 842) were single virus infection. The most common pathogens detected were respiratory syncytial virus (RSV) (44.4%), MP (15.6%), and human rhinovirus (HRV) (14.4%). Coinfection was identified in 13.5% (137 of 1012) of the patients. Coinfection included mixed virus infection and virus infection with MP infection. Children with single virus infection had a higher rate of oxygen therapy compared with single MP infection.

Conclusions

The most common pathogen detected in children with bronchiolitis is RSV, followed by MP and HRV. Coinfection leads to a longer period of illness, increased severity of the symptoms and increased risk of hypoxemia.

Effectiveness of auricular point therapy for cancer-related fatigue: A systematic review and meta-analysis

AIMS

To systemically review the efficacy and safety of auricular point therapy in patients with cancer-related fatigue.

DESIGN

A systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES

Eight electronic databases (PubMed, CENTRAL, Embase, CINAHL, Web of Science, China Biology Medicine, China National Knowledge Infrastructure and WanFang Data Knowledge Service Platform) were explored for randomized controlled trials from their inception to 1 December 2018.

REVIEW METHODS

The risk of bias assessment tool was adopted in accordance with Cochrane Handbook 5.3.0. All included studies reported the effects on cancer-related fatigue as the primary outcome. Effect size was estimated using relative risk, standardized mean difference or mean difference with a corresponding 95% confidence interval. Review Manager 5.3 was used for meta-analysis.

RESULTS

Six studies comprising 394 patients were included. The results of meta-analysis showed that auricular point therapy plus standard care produced more positive effects on cancer-related fatigue and quality of life than standard care alone. It could significantly improve the role, emotional, cognitive, and social functions of patients with cancer-related fatigue.

CONCLUSIONS

Auricular point therapy may be a safe therapy to relieve cancer-related fatigue and enhance the quality of life of patients with cancer. However, the evidence was inconclusive due to limitations on the quantity and quality of included studies. Rigorously designed randomized controlled trials should be conducted to verify the results.

IMPACT

Auricular point therapy is a simple and safe therapeutic approach that may alleviate cancer-related fatigue of common complications in patients with cancer and it is worth promoting in the community, family, and hospital. Moreover, the research findings can provide suggestions and inspiration for nurses and researchers to implement the proposal, which is conducive to design more rigorous and high-quality randomized controlled trials.

Forsythoside A and Forsythoside B Contribute to Shuanghuanglian Injection-Induced Pseudoallergic Reactions through the RhoA/ROCK Signaling Pathway

In recent years, hypersensitivity reactions to the Shuanghuanglian injection have attracted broad attention. However, the componential chief culprits inducing the reactions and the underlying mechanisms involved have not been completely defined. In this study, we used a combination of approaches based on the mouse model, human umbilical vein endothelial cell monolayer, real-time cellular monitoring, immunoblot analysis, pharmacological inhibition, and molecular docking. We demonstrated that forsythoside A and forsythoside B contributed to Shuanghuanglian injection-induced pseudoallergic reactions through activation of the RhoA/ROCK signaling pathway. Forsythoside A and forsythoside B could trigger dose-dependent vascular leakage in mice. Moreover, forsythoside A and forsythoside B slightly elicited mast cell degranulation. Correspondingly, treatment with forsythoside A and forsythoside B disrupted the endothelial barrier and augmented the expression of GTP-RhoA, p-MYPT1, and p-MLC2 in a concentration-dependent manner. Additionally, the ROCK inhibitor effectively alleviated forsythoside A/forsythoside B-induced hyperpermeability in both the endothelial cells and mice. Similar responses were not observed in the forsythoside E-treated animals and cells. These differences may be related to the potential of the tested compounds to react with RhoA-GTPγS and form stable interactions. This study innovatively revealed that some forsythosides may cause vascular leakage, and therefore, limiting their contents in injections should be considered.

Overview of prevention and management of acute bronchiolitis due to respiratory syncytial virus

INTRODUCTION

Respiratory Syncytial Virus (RSV) is the most common cause of Acute Bronchiolitis (AVB) in infants. AVB causes significant morbidity and mortality worldwide, most deaths occurring in the developing world. AVB causes respiratory distress in infants, leading to respiratory failure in some cases. Disease is more severe in infants with risk factors, such as prematurity, chronic cardiac and lung disease and immunodeficiency. Areas covered: Despite major advances in supportive care in the developed world, which has led to a significant reduction in mortality, treatment remains symptomatic and supportive. No specific antiviral treatment has yet proven to be effective. Prevention of disease with monoclonal antibodies has proven to reduce illness severity in those with risk factors, however, this is prohibitively expensive, particularly for the developing world. Prospects for vaccine development are improving. However, because most disease is in young infants, maternal immunization is necessary. However, due to the transient nature of RSV immunity and the circulation of multiple subtypes, vaccines proven to be effective in adult challenge models have yet to be translated to protection in infants. Expert commentary: Despite advances in preventative treatments, adherence to evidence-based guidelines provides the best prospect for successful reduction in morbidity and mortality.

Screening anaphylactoid components of Shuang Huang Lian Injection by analyzing spectrum-effect relationships coupled with UPLC-TOF-MS

Shuang Huang Lian Injection (SHLI) has been used in China for over 30 years as an effective and widely used Chinese herbal prescription to treat acute respiratory infectious. SHLI has, however, caused many severe anaphylactoid reactions. It is important to identify the potential anaphylactoid components of SHLI. Spectrum-effect relationships were used to explore potentially anaphylactoid components. Based on the original herbal formula, honeysuckle, Fructus Forsythiae and Radix Scutellariae extracts were prepared and combined in appropriate proportions. The preparations were then injected into the caudal vein of rats to obtain in vivo serum samples for pharmacological evaluation and fingerprint analysis. The release rate of β-hexosaminidase from RBL-2H₃ cells and plasma histamine level was used as the pharmacological index. Chromatographic fingerprint analysis identified 22 common peaks. Regression analysis and correlation analysis were used to calculate the relationships between the peaks and the pharmacological effects and identified peaks 5, 6, 11, 12 and 17 as likely anaphylactoid agents. The correlated peaks were identified by comparing the fingerprints with in vitro samples and reference standard samples and the structure was identified by UPLC-TOF-MS. This study established a prospective method to clarify the anaphylactoid components in SHLI, which would provide guidances for screening anaphylactoid components in other traditional Chinese medicine injections.
