Management of Rhinitis Medicamentosa: A Systematic Review

Long-term treatment outcomes in refractory rhinitis medicamentosa managed with nasal surgery

BACKGROUND

Limited treatment options exist for refractory Rhinitis Medicamentosa (RM). The role of surgery after failed medical management is not well defined. Mucosal contact points and restricted airflow often perpetuate decongestant use. This study assessed the long-term outcomes of nasal surgery in patients with refractory RM.

METHODS

A prospective cohort study of refractory RM treated with nasal surgery was performed with ≥12 months follow-up. Refractory RM was defined as nasal decongestant use once per day continuously for ≥4 weeks despite medical therapy. Patients with concomitant sinus disease and nonrhinitis conditions were excluded. Sinonasal Outcome Test (SNOT22), Nasal Symptom Score (NSS), and nasal medication use were assessed. Patients who ceased decongestants were compared with ongoing users.

RESULTS

A total of 56 patients (age 48.4 [5.0] years, 50% female) were assessed. Median follow-up was 3.4(1.6-6.2) years. Total cessation of decongestants was achieved in 91.1%, while 5.4% had intermittent use, and 3.6% reported daily use. Ongoing users had higher odds of concomitant asthma (40.0% vs. 3.9%; odds ratio [OR], 16.33 [1.7-159.75]; p = 0.036), reduced symptom improvement (ΔSNOT22, -4.6 [15.7] vs. 27.1 [17], p = 0.009 and ΔNSS, -1.0 [4.2] vs. -6.6 [5.1], p = 0.025), and greater ongoing use of nasal corticosteroid (60.0% vs. 5.9%; OR 24.0 [2.8-203.1]) and saline sprays (40% vs. 3.9%; OR 16.3 [1.7-159.8]) but showed no difference in allergy status (OR, 0.7[0.1-7.1]), previous surgery (OR, 1.0[0.1-10.2]), gastroesophageal reflux (OR 1.0[0.1-10.2], or underlying anxiety/depression (OR 6.1[0.8-45.9]) compared with those who ceased.

CONCLUSION

Surgically re-establishing a nasal airway was associated with long-term decongestant cessation and symptom improvement in medically refractory RM.

Rhinitis medicamentosa - comparing two treatment strategies: a retrospective analysis

OBJECTIVE

Rhinitis medicamentosa poses a therapeutic challenge for both patients and physicians. Treatment strategies vary, starting with avoidance of decongestants, followed by medications or surgical intervention. This study aimed to compare two treatment strategies for this condition.

METHODS

A review was conducted of patients diagnosed with rhinitis medicamentosa from 2013 to 2021, who were managed conservatively with medications or surgically by inferior turbinate reduction.

RESULTS

Forty-seven patients were included: 21 patients were treated conservatively and 26 underwent turbinate reduction. Following surgical therapy, the frequency of using decongestants was significantly reduced (p < 0.001), with a significant improvement in Sino-Nasal Outcome Test-22 scores (p < 0.001). The conservative treatment group was significantly older with more co-morbidities. Following medical therapy, the conservative treatment group had a significant decrease in the frequency of decongestant use, but there was no significant improvement in their Sino-Nasal Outcome Test-22 scores.

CONCLUSION

Compared to conservative treatment, inferior turbinate reduction for rhinitis medicamentosa resulted in reduced decongestant use and improved quality of life.

Quality of life after radio frequency ablation turbinate reduction (RFATR) among patients with rhinitis medicamentosa & withdrawal from decongestant topical spray abuse

OBJECTIVE

Radiofrequency ablation (RFA) reliefs nasal obstruction and improves quality of life (QoL) in patients suffering from inferior turbinate hypertrophy (ITH). A substantial benefit was noted among patients suffering from Rhinitis Medicamentosa (RM), enabling ending decongestant spray abuse. Our aim was to establish the benefit from RFA with respect to QoL in patients suffering from ITH, due to the presence of RM.

STUDY DESIGN

Prospective cohort study.

METHODS

Prospective Cohort study, including patients suffering from ITH undergoing RFA between 9.2017 and 9.2019 in Tel Aviv Medical Center. The cohort was divided to RM and non-RM (including allergic, non-allergic) patients. The differences between the groups were compared before and after RFA, and included patients' complaints, clinical findings and QoL questionnaires (SNOT-22 & NOSE). In the RM group, the ability to wean from decongestants was also described.

RESULTS

Our data demonstrated subjective QoL improvement following RFA (88.9 %, N = 90). All RM patients withdrawaled from nasal decongestant spray. NOSE questionnaire demonstrated a significant improvement in QoL after RFA in the RM group (PV = 0.025). SNOT-22 did not demonstrate significant difference in QoL between RM and the reference group (PV = 0.1). Rates of MCID>8.3 were high, without significant difference between the groups (PV = 0.2).

CONCLUSION

RFA demonstrated effectiveness in achieving of withdrawal from decongestant spray in RM patients and may be a possible definitive treatment option for this group. The nasal obstruction component in SNOT-22 questionnaire & NOSE questionnaire showed improved QoL in comparison to controls. High QoL after RFA was established in our entire cohort.

International consensus statement on allergy and rhinology: Allergic rhinitis - 2023

BACKGROUND

In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document.

METHODS

ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work.

RESULTS

ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost.

CONCLUSION

The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

The role of the topical nasal decongestant oxymetazoline as a novel therapeutic option for post-acne erythema: A split-face, double-blind, randomized, placebo-controlled trial

Post-acne erythema (PAE) is one of the most common sequelae of acne inflammation. Unfortunately, the treatment of PAE remains challenging due to limited effective topical treatments. The objectives of this study were to evaluate the efficacy and safety of topical oxymetazoline hydrochloride (OxH) 0.05% solution for PAE. This study was a split-face, participants-and investigators-blinded, randomized, placebo-controlled trial conducted between December 2021 and March 2022 in Bangkok, Thailand. Healthy adults aged from 18 to 45 years with mild to severe PAE, according to the Clinician's Erythema Assessment (CEA), on both sides of the face were eligible. After randomization, each participant applied the OxH to one side of their face and a placebo to the contralateral face twice daily for 12 weeks. The primary outcome was PAE lesion counts. The secondary outcomes were erythema index, clinical response rate at week 12 ("clear," "almost clear," or "at least two-grade improvement" by CEA), and patient satisfaction scores. A total of 30 participants were enrolled. The OxH-treated skin showed a significantly greater mean difference (MD) reduction in PAE lesion counts than the placebo after 8 weeks of treatment (4.30, 95% confidence interval [CI] 1.42-7.18). Similarly, the MD reduction of the erythema index was higher in the OxH-treated skin from the second week (11.82, 95% CI 8.48-15.15). Additionally, the OxH-treated side also achieved a higher clinical response rate after 8 weeks of treatment (40.00% vs. 6.67%; p = 0.002) and rated higher satisfaction than those using the placebo at the end of the study (mean [standard deviation] satisfaction score 8.30 [0.18] vs 7.40 [0.18], P < 0.001). There were no serious adverse events or flares of erythema during the study. In conclusion, our study demonstrated that the topical OxH 0.05% solution was effective, well-tolerated, and safe for reducing PAE without a rebound effect. It could be a choice of PAE management.

The Indispensable Nasal Decongestant: Patients' Views and Perspectives on Nasal Decongestant Overuse

BACKGROUND

Rhinitis medicamentosa (RM) is a type of nonallergic rhinitis caused by prolonged use of nasal decongestants (NDs). Although it is a preventable phenotype of rhinitis, little is known about patients dealing with this condition.

OBJECTIVE

To gain a better understanding of patients' views and experiences of ND overuse, and potential facilitators and barriers to discontinue the overuse.

METHODS

We performed a qualitative study using in-depth semistructured interviews with 22 patients who have been using an ND on an almost daily basis for at least 6 months. The interviews were conducted face-to-face, audio-recorded, and transcribed verbatim. Data analysis followed the grounded theory approach.

RESULTS

Interviewees described the large impact of nasal congestion on their daily lives. Despite efforts to try other treatment options, the ND was considered the only effective aid to resolve the troublesome symptom. Most participants were aware that the prolonged use was problematic, sometimes leading to hiding behavior in order to avoid criticism by others including their health professionals. Many participants expressed a strong will to discontinue. However, multiple barriers to withdrawal were identified including fear of surgery or the impact of withdrawal on sleep, lack of good alternatives, and negative experiences with past withdrawal attempts. Patients thus face a dilemma in which the barriers to withdrawal currently outweigh the possible benefits.

CONCLUSION

The use of NDs is considered indispensable by many chronic users. The facilitators and barriers identified in this study provide opportunities to reduce the use of NDs and the prevalence of RM in the future.

Management of the Upper Airway Distress During Pregnancy

Pregnancy can induce significant upper airway distress in women by the induction of rhinitis of pregnancy (ROP). Pregnancy can also exacerbate underlying rhinopathies. Little is known regarding the pathophysiology of the ROP. Diagnosis of other coexistent rhinopathies is key. Treatment regimens closely mirror standard treatments for other rhinopathies that are independent of pregnancy and are generally accepted as safe. Early recognition of the progression of rhinitis in the pregnant patient into complications of rhinosinusitis is important to prevent harm to both mother and fetus.

Intranasal corticosteroid and oxymetazoline for chronic rhinitis: a systematic review

OBJECTIVE

This study aimed to summarise the evidence for efficacy of combination treatment of intranasal corticosteroid spray with oxymetazoline hydrochloride nasal spray for chronic rhinitis.

METHOD

Nine databases were systematically searched from study inception in September 2016 to 1 June 2020. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was followed.

RESULTS

A total of 130 studies were screened, and 4 randomised controlled trials comprising 838 patients met inclusion criteria. The study found superior improvement of nasal congestion from onset of treatment to completion in intranasal corticosteroid spray and oxymetazoline hydrochloride groups compared with control groups. Intranasal corticosteroid spray and oxymetazoline hydrochloride use resulted in higher nasal volume (standard error of mean 1, 15.8 + 1.1 ml; p < .03) compared with either placebo (12.1 + 0.9 ml) or oxymetazoline hydrochloride (12.4 + 0.8 ml) alone (p = 0.003).

CONCLUSION

Intranasal corticosteroid spray and oxymetazoline hydrochloride combination treatment may be superior in reducing rhinitis symptoms compared with either intranasal corticosteroid spray or oxymetazoline hydrochloride alone, without inducing rhinitis medicamentosa.

Contemporary Role and Regulation of Over-the-Counter Sinonasal Medications

OBJECTIVE

Numerous pharmaceutical options are available over-the-counter (OTC) for the relief of sinonasal symptoms. Patients typically utilize these drugs in an unsupervised manner, without appreciation of their relative efficacy or potential for adverse effects. This review covers the scope and regulation of the OTC drug market, the pros and cons of OTC availability, and specific concerns that surround the most common classes of OTC sinonasal drugs. Suggestions are provided for the improvement of patient care and public health.

DATA SOURCES

MEDLINE publications and market reports.

REVIEW METHODS

Literature review.

CONCLUSIONS

Some of the most commonly used OTC sinonasal remedies, including decongestants and first-generation antihistamines, are less effective than alternative drugs and pose potential safety concerns.

IMPLICATIONS FOR PRACTICE

Clinicians should advocate to their patients for the appropriate use of alternative agents, such as intranasal corticosteroids and newer-generation antihistamines, and discourage the unsupervised use of oral and topical decongestants. Furthermore, health care practitioners should encourage dialogue with their patients about the use of OTC sinonasal remedies, with the goals of optimizing individual health and health care delivery.

Rhinitis medicamentosa: a nationwide survey of Canadian otolaryngologists

Background

Rhinitis medicamentosa is a non-allergic form of rhinitis that is typically caused by prolonged use of topical nasal decongestants. This condition commonly affects young adults and treatment is not trivial. We aimed to survey Canadian Otolaryngologists to determine practice patterns and their opinions regarding this under-studied condition.

Methods

An electronic survey was sent to practicing Otolaryngologists within the Canadian Society of Otolaryngology – Head and Neck Surgery. The survey contained 16 questions pertaining to the diagnosis and treatment of rhinitis medicamentosa, as well as opinions on public and primary care awareness of proper use of nasal decongestants.

Results

The survey was distributed to 533 Otolaryngologists and 69 surveys were returned (response rate of 13%). Cessation and weaning of decongestant (96%), and intranasal steroids (94%) were the most common methods for treating RM. Intranasal saline rinses (55%) and oral steroids (25%) were also supported by some respondents. For those who recommended cessation/weaning, 61% also concurrently introduced an intranasal steroid during this process. The majority responded that current warnings on nasal decongestants were inadequate (75%), and were not visible enough (79%).

Conclusions

Rhinitis medicamentosa is a common, and very preventable condition. Although the literature lacks a standardized approach to RM, our survey has shown that many Otolaryngologists diagnose and treat RM in a similar manner. Treatment tends to focus on decongestant cessation, often with concurrent introduction of intranasal steroids. It was felt the warning labels on the topical medications are not currently satisfactory.

Intranasal corticosteroids for non-allergic rhinitis

BACKGROUND

Non-allergic rhinitis is defined as dysfunction and non-infectious inflammation of the nasal mucosa that is caused by provoking agents other than allergens or microbes. It is common, with an estimated prevalence of around 10% to 20%. Patients experience symptoms of nasal obstruction, anterior rhinorrhoea/post-nasal drip and sneezing. Several subgroups of non-allergic rhinitis can be distinguished, depending on the trigger responsible for symptoms; these include occupation, cigarette smoke, hormones, medication, food and age. On a cellular molecular level different disease mechanisms can also be identified. People with non-allergic rhinitis often lack an effective treatment as a result of poor understanding and lack of recognition of the underlying disease mechanism. Intranasal corticosteroids are one of the most common types of medication prescribed in patients with rhinitis or rhinosinusitis symptoms, including those with non-allergic rhinitis. However, it is unclear whether intranasal corticosteroids are truly effective in these patients.

OBJECTIVES

To assess the effects of intranasal corticosteroids in the management of non-allergic rhinitis.

SEARCH METHODS

The Cochrane ENT Information Specialist searched the Cochrane ENT Register; Cochrane Central Register of Controlled Trials (CENTRAL 2019, Issue 7); PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 1 July 2019.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing intranasal corticosteroids, delivered by any means and in any volume, with (a) placebo/no intervention or (b) other active treatments in adults and children (aged ≥ 12 years).

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcomes were patient-reported disease severity and a significant adverse effect - epistaxis. Secondary outcomes were (disease-specific) health-related quality of life, objective measurements of airflow and other adverse events. We used GRADE to assess the certainty of the evidence for each outcome.

MAIN RESULTS

We included 34 studies (4452 participants); however, only 13 studies provided data for our main comparison, intranasal corticosteroids versus placebo. The participants were mainly defined as patients with perennial rhinitis symptoms and negative allergy tests. No distinction between different pheno- and endotypes could be made, although a few studies only included a specific phenotype such as pregnancy rhinitis, vasomotor rhinitis, rhinitis medicamentosa or senile rhinitis. Most studies were conducted in a secondary or tertiary healthcare setting. No studies reported outcomes beyond three months follow-up. Intranasal corticosteroid dosage in the review ranged from 50 µg to 2000 µg daily. Intranasal corticosteroids versus placebo Thirteen studies (2045 participants) provided data for this comparison. These studies used different scoring systems for patient-reported disease severity, so we pooled the data in each analysis using the standardised mean difference (SMD). Intranasal corticosteroid treatment may improve patient-reported disease severity as measured by total nasal symptom score compared with placebo at up to four weeks (SMD -0.74, 95% confidence interval (CI) -1.15 to -0.33; 4 studies; 131 participants; I² = 22%) (low-certainty evidence). However, between four weeks and three months the evidence is very uncertain (SMD -0.24, 95% CI -0.67 to 0.20; 3 studies; 85 participants; I² = 0%) (very low-certainty evidence). Intranasal corticosteroid treatment may slightly improve patient-reported disease severity as measured by total nasal symptom score change from baseline when compared with placebo at up to four weeks (SMD -0.15, 95% CI -0.25 to -0.05; 4 studies; 1465 participants; I² = 35%) (low-certainty evidence). All four studies evaluating the risk of epistaxis showed that there is probably a higher risk in the intranasal corticosteroids group (65 per 1000) compared to placebo (31 per 1000) (risk ratio (RR) 2.10, 95% CI 1.24 to 3.57; 4 studies; 1174 participants; I² = 0%) (moderate-certainty evidence). The absolute risk difference (RD) was 0.04 with a number needed to treat for an additional harmful outcome (NNTH) of 25 (95% CI 16.7 to 100). Only one study reported numerical data for quality of life. It did report a higher quality of life score in the intranasal corticosteroids group (152.3 versus 145.6; SF-12v2 range 0 to 800); however, this disappeared at longer-term follow-up (148.4 versus 145.6) (low-certainty evidence). Only two studies provided data for the outcome objective measurements of airflow. These data could not be pooled because they used different methods of outcome measurement. Neither found a significant difference between the intranasal corticosteroids and placebo group (rhinomanometry SMD -0.46, 95% CI -1.06 to 0.14; 44 participants; peak expiratory flow rate SMD 0.78, 95% CI -0.47 to 2.03; 11 participants) (very low-certainty evidence). Intranasal corticosteroids probably resulted in little or no difference in the risk of other adverse events compared to placebo (RR 0.99, 95% CI 0.87 to 1.12; 3 studies; 1130 participants; I² = 0%) (moderate-certainty evidence). Intranasal corticosteroids versus other treatments Only one or a few studies assessed each of the other comparisons (intranasal corticosteroids versus saline irrigation, intranasal antihistamine, capsaicin, cromoglycate sodium, ipratropium bromide, intranasal corticosteroids combined with intranasal antihistamine, intranasal corticosteroids combined with intranasal antihistamine and intranasal corticosteroids with saline compared to saline alone). It is therefore uncertain whether there are differences between intranasal corticosteroids and other active treatments for any of the outcomes reported.

AUTHORS' CONCLUSIONS

Overall, the certainty of the evidence for most outcomes in this review was low or very low. It is unclear whether intranasal corticosteroids reduce patient-reported disease severity in non-allergic rhinitis patients compared with placebo when measured at up to three months. However, intranasal corticosteroids probably have a higher risk of the adverse effect epistaxis. There are very few studies comparing intranasal corticosteroids to other treatment modalities making it difficult to draw conclusions.

Xylitol treats nasal mucosa in rhinitis medicamentosa: an experimental rat model study

OBJECTIVE

Rhinitis medicamentosa is drug-induced rhinitis which occurs by prolonged and overdose usage of topical nasal decongestants. There is not much of treatment choice rather than nasal steroids. In this pathological study, we have been aimed to represent the healing effects of xylitol on damaged nasal mucosa due to rhinitis medicamentosa.

METHOD

30 Wistar rats were separated into 5 groups. During 2 months, oxymetazoline was given to the first group, and saline was given to second group intranasally. First and second group animals were examined at the end of 2 months and rhinitis medicamentosa was detected. Oxymetazoline was given to the third, fourth, and fifth groups during 2 months. Then xylitol solution, mometasone, and saline were applied, respectively, for 15 days. After the experiment, rats' nasal mucosas were evaluated histopathologically.

RESULTS

Xylitol and mometasone were found to be more effective than the control group in terms of histopathological changes. Effectivity of xylitol and mometasone was compared and not a significant value was determined.

CONCLUSIONS

According to the results, xylitol solution is effective as mometasone, usable and well-priced in the treatment of rhinitis medicamentosa. More comprehensive and ultrastructural studies on animals and human studies with rhinometric evaluation should be performed.
