Menopausal hormone therapy may increase non-allergic rhinitis among postmenopausal women: Results from the Korea National Health and Nutrition Examination Survey (2010–2012)

Effect of Hormone Replacement Therapy on Chronic Rhinosinusitis Management

OBJECTIVES

To investigate whether hormone replacement therapy (HRT) impacts health care resource utilization in the management of chronic rhinosinusitis (CRS) in older women.

METHODS

Using the TriNetX US health record database, women 55 years or older with a diagnosis of CRS were included and followed for 3 years. The cohort was stratified into two groups: women who received HRT at the beginning of the study were compared to women who did not receive HRT. The groups were matched by age, race, ethnicity, history of asthma, and history of nasal polyps. Outcomes included whether the patient underwent endoscopic sinus surgery (ESS) and frequency of antibiotic use. Measures of association, Kaplan-Meier analysis, and cohort descriptive statistics were calculated.

RESULTS

Of the 65,400 women included, the mean age was 66.9 years. 27.0% and 3.6% of patients had a history of asthma or nasal polyps, respectively. Overall, 2.0% of CRS patients underwent ESS, with the HRT group less likely to undergo ESS [OR: 0.28; 95% CI: (0.25-0.32)] compared to patients who did not receive HRT. When stratified by polyp status, HRT patients with nasal polyps had a greater decrease in ESS rates compared to control than HRT patients without nasal polyps. The HRT group had a higher mean number of antibiotic prescriptions compared to the non-HRT group.

CONCLUSION

HRT is associated with decreased utilization of ESS to treat CRS, with a greater effect size for ESS among CRSwNP patients. However, HRT was associated with higher antibiotic utilization.

Drug-Induced Rhinitis: Narrative Review

OBJECTIVES

Rhinitis, one of the most common inflammatory conditions of the nasal mucosa, is known to affect a large proportion of people worldwide. It is generally classified into allergic and non-allergic types and both are associated with several unpleasant symptoms. Several medications prescribed for different medical conditions can cause unpleasant rhinitis as an adverse effect, which is known as drug-induced non-allergic rhinitis. The aims of this article were to review the literature to identify drugs that could induce rhinitis, prevalence of drug-induced rhinitis, and the associated pathogenic mechanisms if known.

METHODS

Literature search screening for eligible papers published up to December 31st, 2021, in Medline (via PubMed) and Embase was conducted. The search included the following combination of keywords and terms: rhinitis, sneezing, congestion, allergic, non-allergic, rhinorrhea, vasomotor, medication, drug-induced.

RESULTS

The review findings suggest that 12 subtypes of drugs potentially could induce rhinitis. Based on their mechanisms of action, the pathogenic causes for the induction of rhinitis have been recognized for some drugs, while others remain unknown.

CONCLUSION

Awareness of the list of drugs that reportedly induce non-allergic nasal symptoms, along with taking the patient's medication history, is important in the diagnosis of rhinitis.

Smoking behavior might affect allergic rhinitis and vasomotor rhinitis differently: A mendelian randomization appraisal

Background

Allergic rhinitis and vasomotor rhinitis are harassing numerous patients and their risk factors have not been well investigated. Here, we try to identify their risk factors and distinguish these 2 diseases.

Methods

A two-sample Mendelian randomization (MR) study was implemented to discover the risk factors of allergic and vasomotor rhinitis. Based on previous studies, we selected 15 potential risk factors and the genome-wide summary statistics were extracted from the non-FinnGen consortium. The genome-wide summary statistics of rhinitis were obtained from the FinnGen consortium. Both univariable MR and multivariable MR analyses were performed to identify the causal risk factors. The Cochrane's Q value was calculated to appraise the heterogeneity. MR-Egger intercept and MR-RPESSO were utilized to appraise the pleiotropy.

Results

In the univariable model, the number of cigarettes per day can decrease the risk of allergic rhinitis (IVW OR = 0.29[0.18, 0.47], p-value = 2.70 × 10⁻⁷) while increasing the risk of vasomotor rhinitis (IVW OR = 1.30[1.04, 1.62], p-value = 0.022). Besides, no other risk factors could affect the risk of either allergic or vasomotor rhinitis. After adjusting for age of smoking initiation and alcohol intake, the cigarettes per day could still decrease the risk of allergic rhinitis (IVW OR = 4.66 × 10⁻³ [1.99 × 10⁻⁴, 0.11], p-value = 0.003) while not affecting the risk of vasomotor rhinitis (IVW OR = 0.92[0.44, 1.96], p-value = 0.834).

Conclusion

Smoking can affect the risk of allergic and vasomotor rhinitis differently where it decreases the risk of allergic rhinitis and increases the risk of vasomotor rhinitis.

Rhinitis Phenotypes

Rhinitis is an umbrella term of a group of upper airway diseases with nasal symptoms and signs with different etiologies and various clinical features or traits. It can be classified into different "phenotypes," based on these observable traits. A proper differential diagnosis is necessary to adequately manage the disease. The objective of this review is to clarify the concept of rhinitis phenotypes while analyzing the clinical features and/or traits of each in order to determine a proper differential diagnosis and appropriate treatment.

Rhinitis and Sinusitis in the Geriatric Population

Rhinitis and sinusitis are common medical conditions that affect the geriatric population and have a significant impact on their quality of life. Because few studies examine differences in the clinical management between the geriatric and general adult population, therapies should be based on current guidelines. Special considerations should be made when treating these patients in regards to multiple comorbidities and the potential for drug interactions from polypharmacy. Further research on the pathogenesis of sinusitis in the geriatric population may provide specific differences in the clinical management in this population.
