Abstract
Allergic rhinitis is a common ailment in primary and acute care settings. Diagnosis is clinical, by means of history and physical examination. Referral to an allergist is considered when symptoms are difficult to manage and/or confirmation by means of further testing is desired. Management of allergic rhinitis should not be considered trivial, as multiple secondary effects can present as the course progresses. Several treatment modalities exist but should begin with glucocorticoid nasal sprays and systemic second- or third-generation antihistamines.

Wang E, Diaz A, Zhang D, Dimitroyannis R, Kim D, Caballero N, Pinto JM, Roxbury CR. Impact of social determinants of health on access to rhinology care and patient outcomes: A pilot study. Laryngoscope Investig Otolaryngol 2024; 9:e1192. [PMID: 38362189 PMCID: PMC10866601 DOI: 10.1002/lio2.1192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 10/25/2023] [Accepted: 11/15/2023] [Indexed: 02/17/2024] Open
Abstract
Objective This novel pilot study constructs a social deprivation index (SDI) and utilizes an area deprivation index (ADI) to evaluate the link between social determinants of health and rhinology patient experiences. Methods Adult patients undergoing outpatient care of chronic rhinitis and chronic rhinosinusitis at a tertiary academic medical center were recruited to participate in a telephone survey assessing symptoms, social/emotional consequences of disease, and barriers to care on a 5-point Likert scale. Sociodemographic characteristics were utilized to rate SDI on an 8-point scale. ADI was obtained by area code of residence. Ordered logistic regression was used to examine associations between the SDI/ADI and perceptions of rhinology care. Results Fifty patients were included. Individuals with higher SDI scores (i.e., more socially deprived) experienced more severe nasal congestion (p = .007). Furthermore, higher national ADI correlated with increased severity of smell changes (p = .050) and facial pressure (p = .067). No association was seen between either deprivation index and global/psychiatric symptoms. While no correlations were found between higher SDI and difficulties with the costs of prescriptions, rhinologist's visits, or saline, higher SDI was correlated with decreased difficulty with surgery costs (p = .029), and individuals with higher national ADI percentile had increased difficulties obtaining nasal saline (p = .029). Conclusion Worse social deprivation is associated with difficulties obtaining saline rinses and increased severity of nasal/sinus symptoms in an urban, underserved, majority-Black population. These findings suggest social factors affect access to and quality of rhinology care in a complex and nuanced way and highlight the need for a specific SDI to further study social determinants of health in rhinology.

Abstract
The history of saline nasal irrigation (SNI) is indeed a long one, beginning from the ancient Ayurvedic practices and gaining a foothold in the west at the beginning of the 20th century. Today, there is a growing number of papers covering the effects of SNI, from in vitro studies to randomized clinical trials and literature overviews. Based on the recommendations of most of the European and American professional associations, seawater, alone or in combination with other preparations, has its place in the treatment of numerous conditions of the upper respiratory tract (URT), primarily chronic (rhino)sinusitis, allergic rhinitis, acute URT infections and postoperative recovery. Additionally, taking into account its multiple mechanisms of action and mounting evidence from recent studies, locally applied seawater preparations may have an important role in the prevention of viral and bacterial infections of the URT. In this review we discuss results published in the past years focusing on seawater preparations and their use in clinical and everyday conditions, since such products provide the benefits of additional ions vs. saline, have an excellent safety profile and are recommended by most professional associations in the field of otorhinolaryngology.

Role of nasal saline irrigation in the treatment of allergic rhinitis in children and adults: A systematic analysis. Allergol Immunopathol (Madr) 2020; 48:360-367. [PMID: 32331798 DOI: 10.1016/j.aller.2020.01.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 12/27/2019] [Accepted: 01/02/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND This meta-analysis aims to access the efficacy of nasal saline irrigation in the treatment of allergic rhinitis (AR) in adults and children. METHODS Two authors independently searched databases up to December 2018. Differences in efficacy between saline irrigation and other treatments were compared. Subgroup analyses of discrepancy in effects between children and adults were performed. RESULTS (1) Saline irrigation vs. no irrigation, in both children and adults groups, saline irrigation showed significant efficacy. (2) Saline+medication vs. medication, in children group, there was no statistical difference of efficacy between saline+medication and medication; in adults group, efficacy of saline+medicine was superior to that of medication. (3) Saline irrigation vs. medication, in children group, there was no statistical difference between efficacy of saline irrigation and medication; in adults group, efficacy of medication was superior to that of saline irrigation. (4) Hypertonic saline vs. isotonic saline, for children, efficacy of hypertonic saline was superior to that of isotonic saline. Additionally, no adults reported adverse events in all trials. Adverse effects were reported during the first nasal irrigation in 20 children, and one child withdrew due to adverse reactions. CONCLUSIONS Saline irrigation can significantly improve symptoms of AR in children and adults. Saline irrigation can serve as a safe adjunctive treatment to medication of AR in adults. Saline irrigation can be an alternative therapy for children and pregnant women with AR. Efficacy of hypertonic saline may be better than that of isotonic saline in treating AR of children.

Abstract
Background Nasal irrigations (NI) are increasingly used as an over-the-counter adjunctive treatment for allergic rhinitis (AR), but clinical studies on their effectiveness are limited. Methods An open-label, controlled, non-randomized, real-life study was conducted to evaluate the effectiveness of NI with a new hypertonic solution as add-on treatment for AR. Children and adolescents with AR were prescribed symptomatic treatment. The active group also received an additional sea-water NI solution supplemented with algae extracts. The primary endpoint was symptom control, assessed by the control of allergic rhinitis and asthma test (CARAT) questionnaires. Moreover, the MASK/Allergy Diary was used to track symptoms and daily medication use that were combined in a novel total symptom/medication score (TSMS). Results We assessed 76 patients. Overall, there was a significant improvement of CARAT results (median Z-score change of 1.1 in the active/NI group vs. 0.4 in the control group; p = 0.035). Among patients > 12 years old (n = 51), there was a significant improvement in CARAT10 results among participants receiving NI (21.0 to 25.5; p < 0.001), but not in the regular treatment group (21.5 to 24.0; p = 0.100). For children < 12 years old (n = 25), the ΝΙ group had significantly improved symptom control (CARATKids results: 5.0 to 2.0; p = 0.002), in contrast to the control group (4.0 to 2.5; p = 0.057). MASK data on allergic symptoms were comparable between groups. However, the NI group had lower TSMS, more days with < 20% symptoms and fewer days using symptomatic treatment (26.9% vs. 43.5%; p = 0.005). Conclusion Addition of NI with a sea-water solution to regular treatment improved AR symptom control. CARAT questionnaires and MASK application can be useful outcome tools in real-life studies.

Abstract
BACKGROUND Allergic rhinitis is a common condition affecting both adults and children. Patients experience symptoms of nasal obstruction, rhinorrhoea, sneezing and nasal itching, which may affect their quality of life.Nasal irrigation with saline (salty water), also known as nasal douching, washing or lavage, is a procedure that rinses the nasal cavity with isotonic or hypertonic saline solutions. It can be performed with low positive pressure from a spray, pump or squirt bottle, with a nebuliser or with gravity-based pressure in which the person instils saline into one nostril and allows it to drain out of the other. Saline solutions are available over the counter and can be used alone or as an adjunct to other therapies. OBJECTIVES To evaluate the effects of nasal saline irrigation in people with allergic rhinitis. SEARCH METHODS The Cochrane ENT Information Specialist searched the ENT Trials Register; CENTRAL; Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 23 November 2017. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing nasal saline irrigation, delivered by any means and with any volume, tonicity and alkalinity, with (a) no nasal saline irrigation or (b) other pharmacological treatments in adults and children with allergic rhinitis. We included studies comparing nasal saline versus no saline, where all participants also received pharmacological treatment (intranasal corticosteroids or oral antihistamines). DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. Primary outcomes were patient-reported disease severity and a common adverse effect - epistaxis. Secondary outcomes were disease-specific health-related quality of life (HRQL), individual symptom scores, general HRQL, the adverse effects of local irritation or discomfort, ear symptoms (pain or pressure) and nasal endoscopy scores. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS We included 14 studies (747 participants). The studies included children (seven studies, 499 participants) and adults (seven studies, 248 participants). No studies reported outcomes beyond three months follow-up. Saline volumes ranged from 'very low' to 'high' volume. Where stated, studies used either hypertonic or isotonic saline solution.Nasal saline versus no saline treatmentAll seven studies (112 adults; 332 children) evaluating this comparison used different scoring systems for patient-reported disease severity, so we pooled the data using the standardised mean difference (SMD). Saline irrigation may improve patient-reported disease severity compared with no saline at up to four weeks (SMD -1.32, 95% confidence interval (CI) -1.84 to -0.81; 407 participants; 6 studies; low quality) and between four weeks and three months (SMD -1.44, 95% CI -2.39 to -0.48; 167 participants; 5 studies; low quality). Although the evidence was low quality the SMD values at both time points are considered large effect sizes. Subgroup analysis showed the improvement in both adults and children. Subgroup analyses for volume and tonicity were inconclusive due to heterogeneity.Two studies reported methods for recording adverse effects and five studies mentioned them. Two studies (240 children) reported no adverse effects (epistaxis or local discomfort) in either group and three only reported no adverse effects in the saline group.One study (48 children) reported disease-specific HRQL using a modified RCQ-36 scale. It was uncertain whether there was a difference between the groups at any of the specified time points (very low quality). No other secondary outcomes were reported.Nasal saline versus no saline with adjuvant use of intranasal steroids or oral antihistamines Three studies (40 adults; 79 children) compared saline with intranasal steroids versus intranasal steroids alone; one study (14 adults) compared saline with oral antihistamines versus oral antihistamines alone. It is uncertain if there is a difference in patient-reported disease severity at up to four weeks (SMD -0.60, 95% CI -1.34 to 0.15; 32 participants; 2 studies; very low quality) or from four weeks to three months (SMD -0.32, 95% CI -0.85 to 0.21; 58 participants; 2 studies; very low quality). Although none of the studies reported methods for recording adverse effects, three mentioned them: one study (40 adults; adjuvant intranasal steroids) reported no adverse effects (epistaxis or local discomfort) in either group; the other two only reported no adverse effects in the saline group.It is uncertain if saline irrigation in addition to pharmacological treatment improved disease-specific HRQL at four weeks to three months, compared with pharmacological treatment alone (SMD -1.26, 95% CI -2.47 to -0.05; 54 participants; 2 studies; very low quality). No other secondary outcomes were reported.Nasal saline versus intranasal steroidsIt is uncertain if there was a difference in patient-reported disease severity between nasal saline and intranasal steroids at up to four weeks (MD 1.06, 95% CI -1.65 to 3.77; 14 participants; 1 study), or between four weeks and three months (SMD 1.26, 95% CI -0.92 to 3.43; 97 participants; 3 studies), or indisease-specific HRQL between four weeks and three months (SMD 0.01, 95% CI -0.73 to 0.75; 83 participants; 2 studies). Only one study reported methods for recording adverse effects although three studies mentioned them. One (21 participants) reported two withdrawals due to adverse effects but did not describe these or state which group. Three studies reported no adverse effects (epistaxis or local discomfort) with saline, although one study reported that 27% of participants experienced local discomfort with steroid use. No other secondary outcomes were reported. AUTHORS' CONCLUSIONS Saline irrigation may reduce patient-reported disease severity compared with no saline irrigation at up to three months in both adults and children with allergic rhinitis, with no reported adverse effects. No data were available for any outcomes beyond three months. The overall quality of evidence was low or very low. The included studies were generally small and used a range of different outcome measures to report disease severity scores, with unclear validation. This review did not include direct comparisons of saline types (e.g. different volume, tonicity).Since saline irrigation could provide a cheap, safe and acceptable alternative to intranasal steroids and antihistamines further high-quality, adequately powered research in this area is warranted.

Abstract
Background The "cost of illness" of the acute allergic rhinitis (AR) episodes in patients with chronic AR is very high in terms of therapy and quality of life. AR represents a worldwide health problem; despite the fact that many standardized treatments have been proposed and used, the recurrence rate of acute rhinitis episodes in springtime is always higher. Materials and methods Sixty consecutive patients (13 F and 17 M in group A, 15 F and 15 M in group B; p=0.60) with chronic AR were enrolled in this prospective, controlled clinical trial. Thirty patients were treated daily for the same 5 months of the following year (2013) with isotonic seawater nasal spray enriched with manganese (Sterimar Mn; 4 puffs/day), whereas 30 patients received only the standard care and were used as control group. Results A 5 months course treatment with the nasal Sterimar Mn was able to decrease, significantly (p<0.001), the number of episodes of acute AR (6.33 episodes in the group of treated patients versus 9.33 episodes in control group). Also, the 5 months quality of life reduced over time (Visual Analogue Scale 5th month 9.90 in treated group versus Visual Analogue Scale 5th month 8.72 in control group: p<0.001) without the typical adverse effects of the AR standard care therapy. Conclusion This study shows the effectiveness of the use of Sterimar Mn for a 5 months therapy in terms of reduction of the number of episodes of acute AR and effectiveness of intrasubject improvement of Visual Analog Scale (quality of life).

Abstract
Abstract Introduction: Nasal instillation of saline solution has been used as part of the treatment of patients with upper respiratory tract diseases. Despite its use for a number of years, factors such as the amount of saline solution to be used, degree of salinity, method and frequency of application have yet to be fully explained. Objective: Review the reported outcomes of saline nasal irrigation in adults with allergic rhinitis, acute or chronic sinusitis and after functional endoscopic sinus surgery (FESS), and provide evidence to assist physiotherapists in decision making in clinical practice. Methods: A search was conducted of the Pubmed and Cochrane Library databases between 2007 and 2014. A combination of the following descriptors was used as a search strategy: nasal irrigation, nasal lavage, rhinitis, sinusitis, saline, saline solution. Results: Eight clinical trials were included, analyzed according to participant diagnosis. Conclusion: The evidence found was heterogeneous, but contributed to elucidating uncertainties regarding the use of nasal lavage in the clinical practice of physical therapy, such as the protocols used.

Abstract
Nasal irrigations have been used for centuries without any scientific data to determine its efficacy. Despite their widespread use, much confusion exist about the mechanism of action, preparation, indications and therapeutic advantage of nasal irrigations. Anecdotal evidence and poorly controlled studies add to the confusion. Recent evidence provides strong scientific justification of the benefits and advantages of using nasal irrigations in sinonasal symptoms relief. The present review of the evidence based literature highlights its efficacy and clinical applications.

Abstract
Background Nasal rinsing with an atomizer spray was found to be effective in the treatment of allergic rhinitis. Two parameters express the nasal functions: (1) mucociliary clearance (MCC), and (2) the pH and its stability. MCC is the main factor that defines the time of pollen transition on the nasal mucosa and, therefore, the amount of the allergen glycoprotein elution. Objective We hypothesized that the nasal wash efficacy could be due to the reduction of contact time of the grass pollen on the nasal mucosa (improving MCC). Methods Forty patients with seasonal grass pollen oculorhinitis were randomized in two groups: 20 received three times daily nasal rinsing with hypertonic solution buffered to pH 6.1, before and during the peak pollen season in 2015 (active group), and another 20 patients were allocated to the control group and received no nasal treatment. The daily symptoms score and the use of oral antihistamines when required were evaluated during the grass pollen peak season. All the patients completed the study. Results In comparison with the control group, in the active group, a significant decrease of both nasal symptoms (p = 0.01) and consumption of antihistamines (p = 0.035) was found. Furthermore, the MCC was significantly worse (p = 0.011) only in the control group. Conclusion The nasal treatment maintained the efficiency of the MCC in the patients in the active group, who showed a significant reduction of symptoms and medication score. The MCC decreased the transit time of the pollen on the nasal mucosa, which favored an elution of the allergenic proteins.
