Meta-Analysis Review
BACKGROUND
Acute upper respiratory tract infections (URTIs), including the common cold and rhinosinusitis, are common afflictions that cause discomfort and debilitation and contribute significantly to workplace absenteeism. Treatment is generally by antipyretic and decongestant drugs and sometimes antibiotics, even though most infections are viral. Nasal irrigation with saline is often employed as an adjunct treatment for URTI symptoms despite a relative lack of evidence for benefit in this clinical setting. This review is an update of the Cochrane review by Kassel et al, which found that saline was probably effective in reducing the severity of some symptoms associated with acute URTIs.
OBJECTIVES
To assess the effects of saline nasal irrigation for treating the symptoms of acute URTIs.
SEARCH METHODS
We searched CENTRAL (2014, Issue 7), MEDLINE (1966 to July week 5, 2014), EMBASE (1974 to August 2014), CINAHL (1982 to August 2014), AMED (1985 to August 2014) and LILACS (1982 to August 2014).
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing topical nasal saline treatment to other interventions in adults and children with clinically diagnosed acute URTIs.
DATA COLLECTION AND ANALYSIS
Two review authors (DK, BM) independently assessed trial quality with the Cochrane 'Risk of bias' tool and extracted data. We analysed all data using the Cochrane Review Manager software. Due to the large variability of outcome measures only a small number of outcomes could be pooled for statistical analysis.
MAIN RESULTS
We identified five RCTs that randomised 544 children (three studies) and 205 adults (exclusively from two studies). They all compared saline irrigation to routine care or other nose sprays, rather than placebo. We included two new trials in this update, which did not contribute data of sufficient size or quality to materially change the original findings. Most trials were small and we judged them to be of low quality, contributing to an unclear risk of bias. Most outcome measures differed greatly between included studies and therefore could not be pooled. Most results showed no difference between nasal saline treatment and control. However, one larger trial, conducted with children, did show a significant reduction in nasal secretion score (mean difference (MD) -0.31, 95% confidence interval (CI) -0.48 to -0.14) and nasal breathing (obstruction) score (MD -0.33, 95% CI -0.47 to -0.19) in the saline group. However, a MD of -0.33 on a four-point symptom scale may have minimal clinical significance. The trial also showed a significant reduction in the use of decongestant medication by the saline group. Minor nasal discomfort and/or irritation was the only side effect reported by a minority of participants.
AUTHORS' CONCLUSIONS
Nasal saline irrigation possibly has benefits for relieving the symptoms of acute URTIs. However, the included trials were generally too small and had a high risk of bias, reducing confidence in the evidence supporting this. Future trials should involve larger numbers of participants and report standardised and clinically meaningful outcome measures.

Review
The common cold, or upper respiratory tract infection, is one of the leading reasons for physician visits. Generally caused by viruses, the common cold is treated symptomatically. Antibiotics are not effective in children or adults. In children, there is a potential for harm and no benefits with over-the-counter cough and cold medications; therefore, they should not be used in children younger than four years. Other commonly used medications, such as inhaled corticosteroids, oral prednisolone, and Echinacea, also are ineffective in children. Products that improve symptoms in children include vapor rub, zinc sulfate, Pelargonium sidoides (geranium) extract, and buckwheat honey. Prophylactic probiotics, zinc sulfate, nasal saline irrigation, and the herbal preparation Chizukit reduce the incidence of colds in children. For adults, antihistamines, intranasal corticosteroids, codeine, nasal saline irrigation, Echinacea angustifolia preparations, and steam inhalation are ineffective at relieving cold symptoms. Pseudoephedrine, phenylephrine, inhaled ipratropium, and zinc (acetate or gluconate) modestly reduce the severity and duration of symptoms for adults. Nonsteroidal anti-inflammatory drugs and some herbal preparations, including Echinacea purpurea, improve symptoms in adults. Prophylactic use of garlic may decrease the frequency of colds in adults, but has no effect on duration of symptoms. Hand hygiene reduces the spread of viruses that cause cold illnesses. Prophylactic vitamin C modestly reduces cold symptom duration in adults and children.

BACKGROUND
Chronic rhinosinusitis (CRS) without nasal polyps (CRSsNP) is a common disease that is characterized by multiple inflammatory endotypes. However, the molecular mechanisms in CRSsNP are poorly understood compared with those of polypoid CRS.
OBJECTIVE
Our aim was to identify mechanisms and biomarkers associated with inflammatory endotypes underpinning CRSsNP.
METHODS
Ethmoid tissues and nasal lavage fluids (NLFs) were obtained from control patients and patients with CRS. The gene expression profiles were determined by microarray analysis and quantitative RT-PCR, and expression of proteins was measured by ELISA and Luminex analysis.
RESULTS
Microarray found that compared with their levels of expression in control tissue, the levels of expression of 126, 241, and 545 genes were more than 3-fold and significantly elevated in CRSsNP with type 1 (T1) endotype, type 2 (T2) endotype, and type 3 (T3) endotype, respectively. Selected identified genes were confirmed by RT-PCR. Gene set enrichment analysis suggested that T1 CRSsNP was associated with IFN-γ signaling and antiviral immunity controlled by T cells (T1 and CD8), natural killer cells, and antigen-presenting cells; T2 CRSsNP was associated with STAT6 signaling and IgE-mediated activation controlled by eosinophils, mast cells, T2 cells, group 2 innate lymphoid cells, and antigen-presenting cells; and T3 CRSsNP was associated with IL-17 signaling, acute inflammatory response, complement-mediated inflammation, and infection controlled by neutrophils, T17 cells, B cells, and antigen-presenting cells. The results suggest that T1 (CXCL9 and CXCL10), T2 (eosinophilic proteins and CCL26), and T3 (CSF3) endotypic biomarkers in NLF may be able to distinguish tissue endotypes in CRSsNP.
CONCLUSIONS
Inflammatory endotypes in CRSsNP were controlled by different molecular mechanisms. NLF biomarker assays may allow for more precise and personalized medical treatments in CRS.

Review
Primary ciliary dyskinesia (PCD) is a recessive genetically heterogeneous disorder of motile cilia with chronic otosinopulmonary disease and organ laterality defects in ∼50% of cases. The prevalence of PCD is difficult to determine. Recent diagnostic advances through measurement of nasal nitric oxide and genetic testing has allowed rigorous diagnoses and determination of a robust clinical phenotype, which includes neonatal respiratory distress, daily nasal congestion, and wet cough starting early in life, along with organ laterality defects. There is early onset of lung disease in PCD with abnormal airflow mechanics and radiographic abnormalities detected in infancy and early childhood.

Asian Pacific Journal of Allergy and... Dec 2020Asthma and allergic rhinitis (AR) are chronic inflammatory diseases of airway and affect the disease severity each other. (Clinical Trial)
Clinical Trial Randomized Controlled Trial
BACKGROUND
Asthma and allergic rhinitis (AR) are chronic inflammatory diseases of airway and affect the disease severity each other.
OBJECTIVE
We performed this study to examine whether nasal saline irrigation (NSI) improves bronchial hyperresponsiveness and clinical parameters in children with asthma and allergic rhinitis (AR).
METHODS
We enrolled 20 children with AR and asthma aged between 6-18 years. Patients were randomized into two groups: irrigation group (8 boys and 2 girls) and control group (8 boys and 2 girls). The irrigation group performed daily NSI. All patients received 12-week treatment with montelukast, levocetirizine, and inhaled glucocorticoids. Provocative concentrations of methacholine causing a 20% decrease in FEV1 (PC20), Asthma Control Test (ACT), the Questionnaire for Quality-of-Life Specific to Allergic Rhinitis in Korean Children (QQOL-ARK) and exhaled nitric oxide (FENO) were compared before and after the study.
RESULTS
The PC20 at week 12 was higher than baseline measurements in the irrigation group (P = 0.017), while there was no difference in PC20 before and after treatment in the control group (P = 0.333). ACT score increased after 12 weeks of NSI (P = 0.007), while QQOL-ARK score decreased compared to baseline scores (P = 0.028) in the irrigation group. No differences in ACT and QQOL-ARK were found between weeks 0 and 12 in the control group. No differences were found in the median value of changes in PC20, ACT, QQOL-ARK and FENO between the irrigation and control groups.
CONCLUSIONS
Our results suggest that NSI is beneficial for treatment of asthma and AR in children.

Brazilian Journal of Otorhinolaryngology 2020The extent of epithelial lesion in allergic and non-allergic rhinitis and its association with inflammatory changes in nasal lavage has not been clarified.
INTRODUCTION
The extent of epithelial lesion in allergic and non-allergic rhinitis and its association with inflammatory changes in nasal lavage has not been clarified.
OBJECTIVE
To verify the association between the inflammatory cells in the nasal lavage, epithelial lesion extent and basement membrane thickness, in the nasal mucosa of patients with rhinitis; to determine the cutoff point of the percentage of eosinophils in the nasal lavage associated with the atopic patients.
METHODS
Patients with rhinitis and indication for septoplasty and (or) turbinectomy for turbinate hypertrophy were selected, and were submitted to allergy skin tests, nasal lavage with measurement of albumin and interleukin-8 levels, total and differential counting of cells, and mucosal histopathological analysis to determine the extent of epithelial lesion, and degree of basement membrane thickening.
RESULTS
Fifty-six patients with a median age of 24.5 years and a diagnosis of allergic rhinitis (n=36) and non-allergic rhinitis (n=20) were studied. In atopic subjects, allergy skin tests were positive for Dermatophagoides pteronyssinus in 35 (97.0%) and Lolium perenne in 18 (50.0%). Atopic subjects showed a higher clinical score index of rhinitis compared to non-atopic ones. The total count of cells, neutrophils, and levels of albumin and IL-8 were not different in the nasal lavage of atopic and non-atopic subjects. The cutoff point for eosinophil count in nasal fluid for the distinction between allergic rhinitis and non-allergic rhinitis was 4%. Some degree of epithelial lesion was more frequent in allergic rhinitis (94%) than in non-allergic rhinitis (65%) patients. In the presence of basement membrane thickness, as a marker of remodeling, there was no difference in the nasal lavage of patients with allergic rhinitis and non-allergic rhinitis.
CONCLUSION
In this series, 4% was the cutoff point for the number of eosinophils in the nasal lavage, for atopy differentiation. Upper airway remodeling accessed by basement membrane thickness showed similar inflammatory cell infiltrate in the nasal lavage, regardless of the presence of atopy.

Review
Allergic rhinitis patients suffer various symptoms such as sneezing, runny nose, and nasal congestion. As disease severity and chronicity progress, nasal hyperresponsiveness (NHR) develops in those patients. During the generation of a mouse allergic rhinitis model, we discovered that immunized mice developed NHR upon repeated nasal antigen challenge. Using genetically modified mice and an originally developed T cell-transferred mouse model, we confirmed the critical role of CD4 T cells after differentiation into several helper subsets in NHR. On the other hand, immunoglobulin E/mast cell-dependent responses that are critical for evoking nasal symptoms and eosinophils that accumulate in allergic inflammation sites were dispensable. A steroid, but not drugs targeting mast cell-derived mediators, was effective in alleviating NHR. The possible generation of a new means to treat allergic rhinitis by targeting T cell-derived NHR-inducing factors is suggested.

Review
Differential diagnosis plays a key role in diagnosing specific types of allergic rhinitis. The method involving allergen-specific immunoglobulin E (sIgE) detection in nasal lavage fluid, which has continually been the object of standardization efforts, is characterized by high specificity/sensitivity and plays a special role in diagnosing local allergic rhinitis. This article is a systematic review of the literature on the methodology, standardization, and use of sIgE detection in nasal lavage fluid in patients undergoing diagnostic tests for allergic rhinitis.

Scandinavian Journal of Primary Health... Mar 2021To explore the opinions, the usage and the patient education given on nasal saline irrigation by physicians and pharmaceutical personnel working in Finland.
OBJECTIVES
To explore the opinions, the usage and the patient education given on nasal saline irrigation by physicians and pharmaceutical personnel working in Finland.
DESIGN
An internet-based survey with predetermined, multiple-choice answers.
SETTING
Primary care centres, occupational health centres and private care centres in Eastern Finland as well as pharmacies in Finland.
MAIN OUTCOME MEASURES
Healthcare professionals views, practice and general knowledge of nasal irrigation for sinonasal symptoms and conditions.
RESULTS
We received 595 completed surveys (110 physicians, 485 pharmacists). The majority of the respondents recommended nasal saline irrigation for their patients either as a symptomatic treatment (98.0%) or to treat a specific condition (97.5%) such as acute rhinosinusitis, chronic rhinosinusitis and allergic rhinitis. Nasal saline irrigation was also often recommended as a prophylaxis for airway-infections (71.9%) and to enhance the health of the nasal mucosa (58.2%). In general, the possible adverse effects were recognised poorly by both professions. There was a clear difference between the two professions, as physicians were more conservative in recommending nasal saline irrigation and recognised possible adverse effects, such as epistaxis, pain, and dryness of the nose, better (75% vs. 59%, = 0.002).
CONCLUSIONS
Nasal saline irrigation seems to be a popular treatment recommended by many health care professionals in Finland. Physicians and pharmaceutical personnel had variable opinions on the indications, utility and risks of nasal saline irrigation. There are also clear differences between physicians and pharmaceutical personnel's practices. There is a need to better educate professionals about nasal saline irrigation and to further study whether nasal saline irrigation is efficient and safe option for the different common sinonasal conditions.KEY POINTSLittle information is available on how physicians and pharmacists recommend nasal saline irrigation as a symptomatic treatment.Physicians and pharmacists seem to have variable opinions about the indications, utility and safety of nasal saline irrigation.The patient education given is in general very heterogenous.Both professions require more education to ensure that the usage remains as safe as possible for the patient.

Review
The nose exerts many functions, mainly for the respiration and the olfaction and represents the first doorway for the oxygen, but also for pathogens. The present Supplement reports some clinical experiences concerning the use of a new internal nasal dilator in different settings, including nasal obstructive disorders, obstructive sleep apnea syndrome, continuous positive active pressure (CPAP), and sport activity. The outcomes support the concept that a healthy nose should be maintained ever patent and free from secretions, as impaired nasal function can significantly affect quality of life. Therefore, an "open and clean nose" contributes in a relevant way to the subjective wellness.
