Nasal allergies in the Middle Eastern population: results from the "Allergies in Middle East Survey"

Onset of efficacy of azelastine hydrochloride 0.15% nasal spray for allergic rhinitis in an environmental exposure chamber

BACKGROUND

Azelastine nasal spray is effective in relieving symptoms of seasonal and perennial allergic rhinitis.

OBJECTIVE

To evaluate the time to onset of efficacy of azelastine hydrochloride (HCl) 0.15% vs placebo in participants with seasonal allergic rhinitis.

METHODS

A total of 110 participants aged 18 to 65 years were randomized to receive azelastine HCl 0.15% 2 sprays per nostril vs placebo nasal spray after being continuously exposed to ragweed pollen in an environmental exposure chamber. Symptoms were evaluated subjectively by the total nasal symptom score (TNSS) scale. The primary efficacy parameter was the time to onset of efficacy of azelastine as measured by the change from baseline in TNSS 15, 30, 45, 60, 90, 120, 180, and 240 minutes post-dose.

RESULTS

The azelastine nasal spray group had statistically significant improvement in TNSS compared with placebo 30 minutes post-dose (P = .0002), and the effect was sustainable throughout the environmental exposure chamber session for all subsequent time points (P < .0001). Adverse events were mild, including bitter taste, nasal discomfort, epistaxis, sinusitis, and nausea. No major adverse events were reported during the study.

CONCLUSION

Azelastine HCl 0.15% nasal spray relieves nasal symptoms associated with allergic rhinitis and has a fast onset of action within 30 minutes. The overall safety profile of azelastine has also been proven to be safe. These results, along with previous findings on efficacy and improved quality of life for people with allergic rhinitis, establish the important clinical role of azelastine HCl 0.15%.

Patients' values and preferences for health states in allergic rhinitis-An artificial intelligence supported systematic review

BACKGROUND

Allergic rhinitis (AR) impacts patients' physical and emotional well-being. Assessing patients' values and preferences (V&P) related to AR is an essential part of patient-centered care and of the guideline development process. We aimed to systematically summarize the information about patients' V&P on AR and its symptoms and impact on daily life.

METHODS

We conducted systematic review in a MEDLINE, Embase, PsychInfo, and CINAHL databases. We included studies which quantitatively assessed patients' V&P for specific outcomes in AR by assessing utilities, applying discrete choice approaches, or rating and ranking outcomes. We grouped outcomes as AR symptoms, functional status, and care-related patient experience. Study selection and data extraction were supported by the Laser AI tool. We rated the certainty of evidence (CoE) using the GRADE approach.

RESULTS

Thirty-six studies (41 records) were included: nine utility studies, seven direct-choice studies and 21 studies of rating or ranking outcomes. Utilities were lower with increased AR severity and with the concomitant presence of asthma, but not with whether AR was seasonal or perennial (CoE = low-high). Patients rated AR symptom-related outcomes as more important than those related to care-related patient experience and functional status (CoE = very low-moderate). Nasal symptoms (mainly nasal congestion) followed by breathing disorders, general and ocular symptoms were rated as the symptoms with the highest impact.

CONCLUSIONS

This systematic review provides a comprehensive overview of V&P of patients with AR. Patients generally considered nasal symptoms as the most important. Future studies with standardized methods are needed to provide more information on V&P in AR.

Effect of Anesthesia on Endoscopic Sinus Surgery Hemostasis: A State-of-the-Art Review

Endoscopic sinus surgery (ESS) is the gold standard for the management of chronic rhinosinusitis, nasal polyposis, and other pathology involving paranasal sinus as tumors. Intraoperative bleeding during ESS can be challenging due to the narrow sinonasal surgical field, single working hand, and the use of endoscopic instruments, which may affect hemostasis. There is a role for the type of anesthesia technique used for intraoperative bleeding control. Total intravenous anesthesia (TIVA) and inhalational anesthesia (IA) are some of the techniques available for anesthetic purposes. While both techniques have their advantages and disadvantages, there is a need to compare their efficacy and safety to determine which technique is more appropriate for ESS. In this review, our main focus was to summarize the current evidence about the different techniques of anesthesia used during ESS. A systematic review of the PubMed/MEDLINE database was performed using specific English terms related to TIVA and IA/volatile anesthesia used during ESS. A total of 548 publications were considered. Among these, 329 studies did not fulfill the criteria for inclusion in the systematic review, resulting in the inclusion of only 132 publications: 13 systematic reviews, 32 reviews, 92 randomized controlled trials, and 13 meta-analyses. The state of the art favors the use of TIVA during ESS due to its significant improvement in the intraoperative surgical field with less blood loss. Further studies aim to compare long-term nasal status with objective tools, ideally in similar pathology with the same surgeon.

Prevalence and Risk Factors of Allergic Diseases Among School Students in Tabuk: A Cross-Sectional Study

BACKGROUND

Allergic diseases such as bronchial asthma, allergic rhinitis, and atopic dermatitis are common health problems among children. The prevalence of different allergic diseases is increasing in the Kingdom of Saudi Arabia.

OBJECTIVES

This study aimed to estimate the prevalence and risk factors of allergic diseases among school students in Tabuk, Saudi Arabia.

METHODS

This cross-sectional analytical study was conducted in Tabuk city, Saudi Arabia, between the first of August and the end of September, 2022. Students from primary, intermediate, and secondary schools were included. A predesigned, structured, self-administered questionnaire in the Arabic language was used to collect data.

RESULTS

This study included 384 school students from Tabuk, Saudi Arabia. The age of the recruited students ranged from five to 19 years old. The prevalence of clinically diagnosed bronchial asthma that occurred at any time in the past was 31.8%. The prevalence of asthma symptoms was 51.0% for lifetime wheezing and 45.8% for current wheezing (in the past 12 months). The prevalence rates of clinically diagnosed allergic rhinitis and atopic dermatitis were 56.8% and 30.2%, respectively. Further, 68.2% of the school students had one or more of the diagnosed allergic diseases. The second or more childbirth orders were significantly associated with an increased risk of allergic diseases (adjusted odds ratio [AOR] = 3.140, 95% CI: 1.864-5.288). A family history of asthma or atopic conditions showed 3.118 times increased likelihood of allergic conditions (AOR = 3.118, 95% CI: 1.827-5.320). Other significant risk factors were the father's smoking (AOR = 1.698, 95% CI: 1.024-2.817) and having a dog, cat, or bird at home (AOR = 0.493, 95% CI: 0.257-0.946).

CONCLUSION

The prevalence of bronchial asthma and other allergic diseases such as allergic rhinitis and atopic dermatitis among school students in Tabuk city, Saudi Arabia, is alarmingly high. Furthermore, both genetic and environmental components of allergic disease pathogenesis have been identified as risk factors.

Prevalence and Risk Factors of Allergic Rhinitis Among the Population in the Makkah Region, Saudi Arabia: A Cross-Sectional Study

Background Allergic rhinitis (AR) is considered a high global disease burden; hence, the shortage of knowledge would lead to poor adherence to management and preventive measures and increase the exacerbation of AR symptoms. This study aimed to evaluate the prevalence and risk factors, and assess the knowledge and practices of the population regarding AR among the population in Makkah city, Saudi Arabia. Methodology This was an online survey cross-sectional study conducted in December 2022 via social media platforms (WhatsApp and Twitter) to collect data on participants' demographics, prevalence, risk factors, knowledge, and attitudes toward AR, using a validated Arabic version of a self-administered questionnaire. Results The study involved 466 participants. Of the participants, 55.8% were aged 31 to 45 years, and 286 (61.4%) were females. The prevalence of AR among the participants was 45%. The most common symptoms were a blocked nose (79.6%), sneezing (74.2%), and a runny nose (71.5%). Furthermore, the prevalence of rhinoconjunctivitis in this study was 56%. The most common inhalant allergen was house dust (73.0%). Only the age and history of asthma or eczema were significant factors associated with AR. Overall, most of the subjects (94.85%) had adequate knowledge regarding AR. Conclusion A high prevalence of AR was observed. Understanding the factors linked with AR is imperative to ensure better adherence to preventive management plans.

Determinants of uncontrolled allergic rhinitis in Kinshasa hospitals

Objective

To identify the determinants of uncontrolled allergic rhinitis (UCAR) in a hospital setting in Kinshasa, Democratic Republic of Congo.

Methods

Hospital-based cross-sectional study of 153 patients with allergic rhinitis (AR). The diagnosis of AR was based on clinical grounds according to the Allergic Rhinitis and its Impact on Asthma (ARIA) criteria. Categorization into controlled AR (CAR) and UCAR was based on the visual analog scale (VAS with cut off point of 5). Binary logistic regression was used to identify factors associated with UCAR.

Results

Patients with UCAR (60.1%) proportionally outnumbered those with CAR (39.9%). There were significantly more patients younger than 30 years of age among patients with UCAR. Factors significantly associated with UCAR were age below 30 years (OR = 3.31; 95% CI: 1.49-7.36; p = 0.003), low serum vitamin D level (OR = 3.86; 95% CI: 1.72-8.68; p = 0.001), persistent form (OR = 3.11; 95% CI: 1.39-6.98; p = 0.006) and moderate to severe form of AR (OR = 4.31; 95% CI: 1.77-10.49; p = 0.001).

Conclusions

Factors associated with UCAR in this study population were younger age less than 30 years, low vitamin D level, and persistent as well as moderate to severe AR. Further studies are needed to elucidate the underlying mechanisms favoring the occurrence of these factors.

The Prevalence, Clinical Picture, and Triggers of Allergic Rhinitis in Saudi Population: A Systematic Review and Meta-Analysis

Objective

To summarize the current evidence regarding the prevalence of Allergic rhinitis (AR) and its symptoms, triggers, and impact on the quality of life of the Saudi population.

Methods

A Computerized Search in MEDLINE via PubMed, MEDLINE Core database, Scopus, and Web of Science was conducted using relevant keywords. A two-stage screening process, data extraction, and quality assessment were conducted by four independent reviewers. Comprehensive Meta-analysis was used for all statistical analyses (CMA; USA: version 3.3.070).

Results

Sixteen articles (n= 31,990 patients) were included. The overall estimated prevalence of AR was 21.2%, 95% CI (12.8-33.1%). Males had a higher prevalence of AR than females (31.7% vs 27.1%), although the difference was not significant (OR=1.24, 95% CI: 0.78-1.953; p=0.356). Children and adolescents exhibited a lower prevalence of AR than adults (13.7% vs 31.1%). Urban AR prevalence was much greater than rural (38.4% vs 13.0%). Asthma, atopic dermatitis, and eczema are all associated with AR. The most common signs and symptoms of AR were headache 33.9%, watery discharge 28.6%, sneezing 24.6%, itchy nose, runny nose 22.2%, nasal obstruction or congestion 22.0%, loss of smell 21.9%, and wheezing 17.2%. The most prevalent triggers of AR were perfume 36.8%, dust 27.3%, air conditioning 23.4%, weather or temperature changes 17.8%, air pollution 14.5%, drugs or chemicals 13.8%, tobacco 10.8%, atopy 10.3%, and insects 10.2%.

Conclusion

The overall prevalence of AR in Saudi Arabia is 21.2%. The prevalence of AR was comparable in both males and females. However, it was higher in adults than in children and adolescents, and in urban areas than rural areas. Asthma, atopic dermatitis, and eczema co-occurrence with AR are common. AR has a negative impact on the quality of life of the patients in the form of interference with daily activities, sleep problems, difficulty of breath, and school absenteeism.

Prevalence and risk factors of the pregnancy rhinitis at Tikrit General Hospital, Tikrit City, Iraq

Background

Pregnancy rhinitis (PR) is a relatively common condition with a prevalence of 20%. We aimed to identify the prevalence and risk factors of the PR. A prospective cohort study was conducted at the Obstetric and Gyenocology and Otolaryngology Departments in the Tikrit General Hospital, Tikrit City, Iraq. The study covered 12 months (September 2019–September 2020). Pregnant women were divided into two groups; with and without PR. Data regarding the age, body mass index (BMI), occupation, smoking, clinical features, parity, gestational age, and sex of the baby were recorded. Visual analog scale (VAS) and nasal-obstructive-symptom-evaluation (NOSE) scale were used for the evaluation of the nasal obstruction.

Results

The prevalence of the PR was 11.65% (110/944 pregnant women). Rhinorrhea was the commonest associated feature with nasal obstruction of the PR (n = 48, 43.6%). Ninety percent of the patients were in the age group < 35 years. The majority of the subjects were housewives (n = 551, 58.4%), in the second trimester (n = 456, 48.3%), and in the parity group 0–2 (n = 511, 54.1%). The female baby was found in 56.5% of the patients (n = 533). There were statistically significant differences between the two groups: women with and without PR regarding the BMI and gestational age (first trimester) (P value = 0.001). No history of current smoking was found in all women.

Conclusion

The prevalence of PR was 11.65% and was mostly seen in the first trimester. High BMI and pregnant women in the first trimester were considered risk factors for the PR.

Patterns of allergic rhinitis among adults in Qassim region, Saudi Arabia: a cross sectional study

Introduction

developing and developed countries have a high prevalence of allergic rhinitis (AR). Severe AR has negative impacts on sleep, quality of life, and work performance. The study aimed to identify the patterns of AR among patients attending the ears nose and throat Unit (ENT) clinic at King Saud Hospital, Qassim, Saudi Arabia.

Methods

this study was a cross-sectional study conducted at the ENT clinic of King Saudi Hospital, Unaizah City, Qassim region, Saudi Arabia. We examined outpatients diagnosed with AR using an interview questionnaire and clinical examination.

Results

the sample included 455 patients. Of these, 23.7% were 21-30 years old, 65.7% had a family history of AR, 57.8% had no general symptoms, 75.6% reported runny nose as the most common nasal symptom, and 35.4% reported no complications. Dust was the most common trigger of AR (82.4%), 49.2% reported allergic symptoms in all seasons, 96% of patients have inferior turbinate hypertrophy, and oral histamine was the most commonly used treatment (33.2%).

Conclusion

perineal AR and inferior turbinate hypertrophy were very common findings comparing to previous studies, further studies to assess the risk factors are highly recommended.

Prevalence of asthma and allergies among children in the United Arab Emirates: A cross-sectional study

BACKGROUND

Asthma, allergic rhinitis, and atopic dermatitis are the most common chronic inflammatory disorders in children worldwide. These conditions place a significant burden on the healthcare system due to their multiple related complications and the necessity of hospital visits. This study aimed to evaluate the prevalence and severity of asthma and allergic diseases among school children aged 6-7 years and 13-14 years in Dubai and the Northern Emirates, United Arab Emirates (UAE).

PATIENTS AND METHODS

This was a multicenter, cross-sectional study that recruited children from March to June 2019 via school class registers in Dubai and the Northern Emirates, UAE. The Arabic and English versions of the International Study of Asthma and Allergies in Childhood (ISAAC) core questionnaires on asthma, allergic rhinitis, and atopic dermatitis were completed by parents or legal guardians of children aged 6-7 years, and by the children themselves in those aged 13-14 years.

RESULTS

In this study, we included 3436 children (1944 children aged 6-7 years and 1793 children aged 13-14 years). We estimated the prevalence of asthma (11.9%), wheezing (44.2%), allergic rhinitis (46.5%), hay fever (22.1%), and atopic dermatitis (12.9%) in the 6- to 7-year-old group. In the 13- to 14-year-old group, the prevalence was 9.8%, 33.1%, 51.3%, 19.9%, and 14.6%, respectively. The prevalence of any history of asthma was higher in boys than girls in the 6- to 7-year-old group (13.9% vs. 10%) and in the 13- to 14-year-old group (11.2% vs. 8.7%). In the 6- to 7-year-old group, the highest prevalence of asthma, sneezing, and atopic dermatitis was observed in Dubai, Ajman, and Umm Al Quwain, respectively. In the 13- to 14-year-old group, the highest prevalence of asthma was observed in Ras Al Khaimah, and the highest prevalence of sneezing and atopic dermatitis was observed in Sharjah.

CONCLUSION

We found that the prevalence of asthma, allergic rhinitis, and atopic dermatitis in the UAE is comparable to that in neighboring countries; the prevalence of asthma, wheezing, and hay fever was higher in the 6- to 7-year-old group, while in the 13- to 14-year-old group, the prevalence of allergic rhinitis and atopic dermatitis was higher. Overall, the prevalence of any history of asthma was highest in Ras Al Khaimah, followed by Dubai, and lowest in Ajman. Our findings suggest that allergic disorders represent a healthcare burden in the UAE and more efforts are needed to organize nationwide campaigns to detect undiagnosed children to overcome the burden caused by these conditions.

Evaluation of Community Pharmacists' Professional Practice and Management of Patient's Respiratory Conditions

Objectives:

We assessed the extent of community pharmacists managing respiratory conditions and their ability to make differential diagnoses between the common cold and allergic rhinitis.

Methods:

A simulated patient technique was used to achieve the study objectives. Thirty community pharmacies were randomized to be visited by a patient with allergic rhinitis symptoms, followed by a patient with common cold symptoms, and vice versa. One simulated patient visited the 15 pharmacies assigned to allergic rhinitis. Then, after 3–4 days, the pharmacies were revisited by a second simulated patient using the same symptoms; likewise, a simulated patient visited the other 15 pharmacies with common cold symptoms. Then, these pharmacies were revisited by the other simulated patient with the common cold symptoms. Descriptive statistics and correlation analyses were carried out using SPSS at alpha 0.05.

Results:

Fifteen pharmacies were used for the common cold scenario and 15 for the allergic rhinitis scenario (a total of 30 visits per scenario). Pharmacists showed overall poor skills in asking questions for differential diagnosis between the two conditions. No significant difference was found in the overall differential diagnosis score between the two groups (P = 0.744). The overall adherence to the labeling standard score was low, with an average of 2.38 (standard deviation [SD] = 2.50) out of 11, with no significant difference between the two scenarios (P = 0.332). The overall adherence score to the counseling standard was low, with an average of 2.93 (SD = 3.74) out of 15, with no significant difference between the two scenarios (P = 0.586).

Conclusion:

The simulated patient technique approach revealed a lack of ability of pharmacists in Amman, Jordan, to make differential diagnoses between the common cold and allergic rhinitis. In addition, pharmacists lacked the ability to carry out their role with respect to the management of the common cold and allergic rhinitis, including treatment recommendations, adherence to medicine labeling standards, and adherence to the counseling standard.

Effect of Intranasal Corticosteroids on Intraocular Pressure and Nerve Fiber Layer Thickness: A Cross-Sectional Study at a Tertiary Care Hospital in Western Saudi Arabia

Background

Rhinitis represents a global health problem, affecting 10%-20% of the population in Saudi Arabia. Topical intranasal corticosteroids (INCS) are widely used by otolaryngologists to treat patients with rhinitis for long periods. Although the effects of orally administered corticosteroids on intraocular pressure (IOP) and lens opacity are well established, the impact of INCS is not well defined. In the present study, we aimed to assess the effect of using INCS on IOP over a six-month period in patients with rhinitis.

Methodology

In this study, a questionnaire was distributed to 93 patients diagnosed with rhinitis in the Ear, Nose, and Throat Clinic of King Abdulaziz University Hospital, Saudi Arabia, between February and July 2019. Thereafter, each patient was evaluated in the Ophthalmology Clinic with optical coherence tomography of the optic nerve using Cirrus HD-OCT (Carl Zeiss Meditec, Inc., Dublin, CA, USA) optic disc scans, visual acuity testing, and Goldmann applanation tonometry. Pearson correlation coefficients and two-tailed tests of significance were used to assess the relationships between variables.

Results

All 93 patients were using a dose of two puffs at least twice daily for each nostril. Their IOPs, as depicted by Goldman applanation tonometry, were found to be within normal limits. Retinal nerve fiber layer thickness was also found to be normal in 95% of the participants.

Conclusions

Our study showed no correlation between INCS and IOP. As an increase in IOP can lead to glaucoma, our data demonstrate the safety profile of INCS use. For patients with rhinitis, this finding could change compliance to medication and reduce the burden of the disease.

Allergic rhinitis, asthma and laryngopharyngeal reflux disease: a cross-sectional study on their reciprocal relations

Allergic rhinitis (AR) is a common medical condition worldwide. It is an inflammation in the nasal mucosa due to allergen exposure throughout the year. Laryngopharyngeal reflux (LPR) is another medical condition that can overlap with AR. LPR can be considered an extra oesophageal manifestation of gastro-oesophageal reflux disease (GORD) or a different entity. Its diagnosis imposes a real challenge as it has a wide range of unspecific symptoms. Although AR and LPR are not life-threatening, they can severely affect the quality of life for years and cause substantial distress. Moreover, having AR is associated with having asthma which is also in turn associated with GORD. This is a cross-sectional study which used surveys distributed online on Social Media and targeted people across Syria. All participants who responded to the key questions were included. Reflux symptom index (RSI) was used for LPR, and score for allergic rhinitis (SFAR) was used for AR. Demographic questions and whether the participant had asthma were also included in the survey. We found that there was an association between the symptoms of LPR and AR p < 0.0001 (OR, 2.592; 95% CI 1.846-3.639), and their scores were significantly correlated (r = 0.334). Having asthma was associated with LPR symptoms p = 0.0002 (OR 3.096; 95% CI 1.665-5.759) and AR p < 0.0001 (OR 6.772; 95% CI 2.823-16.248). We concluded that there was a significant association between having LPR, AR, and asthma. We need more studies to distinguish between their common symptoms and aetiologies.

Safety Concerns of Nasal Corticosteroids Usage in Patients With Allergic Rhinitis

Background

Intranasal corticosteroids (INCSs) are the first-line treatment for patients with moderate to severe conditions of allergic rhinitis (AR) as per current guidelines. However, patients' knowledge and practice towards the safety of such medications remains ambiguous. Therefore, this study was undertaken to identify the awareness of and knowledge about the safety of nasal corticosteroid usage in patients with allergic rhinitis as well as their adherence to taking the medication.

Materials and methods

We conducted a cross-sectional study from June to September 2020 at Imam Mohammad Ibn Saud Islamic University Medical Center, Riyadh, Kingdom of Saudi Arabia. Data were collected through questionnaire-based surveys, and a total of 375 patients were enrolled in the study. The eligibility criteria included all adult patients diagnosed with allergic rhinitis.

Results

Most of the patients had used intranasal corticosteroids. However, only two-fifths of patients stated these medications were effective and only 27% thought they were safe to use. More than half of the patients expressed concerns about using intranasal corticosteroids; however, there was no difference among the patients when asked if their concerns made them discontinue their medication. The majority of patients (73.3%) did not receive appropriate advice on how to use intranasal corticosteroids, but most were compliant with the therapy regardless of their uncertainty about the medication’s safety (71.5%). Most patients reported a benefit of using intranasal corticosteroids (71.5%). Half of the patients (53.9%) reported being aware of a special technique for how to use a nasal spray, but the nonsmokers were more knowledgeable about the techniques than the smokers (p = 0.007).

Conclusion

The patients' knowledge about, adherence to, and perceptions of intranasal corticosteroid use were found to be suboptimal. Patients’ age, gender, socioeconomic status, education level, and smoking status were recognized as potential barriers to a positive perception of and adherence to the treatment plan. Corrective measures are needed to ensure better health outcomes.

The association between airborne pollen monitoring and sensitization in the hot desert climate

Background

Pollen is a major cause of allergic respiratory diseases. In Qatar, data on the presence and prevalence of allergenic airborne types of pollen is quite limited.

Methods

The study aimed to determine and correlate the most frequently implicated airborne pollen detected by aerobiological monitoring samplers in respiratory allergy symptoms. An aerobiological survey was started on May 8, 2017. Airborne pollen was collected using two Hirst type seven-day recorder volumetric traps. Skin prick test in patients attending allergy clinics in Doha using commercial extracts was conducted.

Results

Twenty-five pollen types representing the native, as well as the introduced plants, with a relatively low daily mean concentration were observed from May 2017 to May 2019. The highest pollen concentrations were reached by Amaranthaceae (58.9%), followed by Poaceae (21.7%). SPT revealed a comparatively higher degree of sensitization to pollen. Among 940 patients, 204 were sensitized to pollen (54% female) with 135 (66.2%) and 114 (55.8%) to Amaranthaceae and Poaceae, respectively. Some patients had polysensitization. There was a statistically significant association between Amaranthaceae, and asthma (r = 0.169, P = 0.016) and allergic rhinitis (r = 0.177, P = 0.012).

Conclusions

This is the first study to monitor airborne pollen in the state of Qatar. The main pollen detected were Amaranthaceae and Poaceae. Pollen may represent a possible exacerbating factor in adult patients with allergic diseases such as asthma and allergic rhinitis.

The efficacy and safety of acupoint application combined with western medicine for allergic rhinitis: A protocol for systematic review and meta-analysis

BACKGROUND

Acupoint application combined with western medicine has been used for treating allergic rhinitis widely. However, the efficacy and safety of acupoint application combined with western medicine for allergic rhinitis are unclear. This study aims to evaluate the efficacy and safety of acupoint application combined with western medicine for allergic rhinitis.

METHODS

Randomized controlled trials of acupoint application combined with western medicine for allergic rhinitis will be searched in PubMed, EMbase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, WanFang, the Chongqing VIP Chinese Science and Technology Periodical Database, and China biomedical literature database from inception to July, 2020. And Baidu Scholar, Google Scholar, International Clinical Trials Registry Platform, and Chinese Clinical Trials Registry will be searched to obtain more relevant studies comprehensively. Two researchers will perform data extraction and risk of bias assessment independently. Statistical analysis will be conducted in RevMan 5.3.

RESULTS

This study will summarize the present evidence by exploring the efficacy and safety of acupoint application combined with western medicine for the treatment of allergic rhinitis.

CONCLUSIONS

The findings of the study will provide helpful evidence for the efficacy and safety of acupoint application combined with western medicine in the treatment of allergic rhinitis, facilitating clinical practice and further scientific studies.

Allergic Rhinitis and Its Epidemiological Distribution in Syria: A High Prevalence and Additional Risks in War Time

BACKGROUND

Allergic rhinitis (AR) is a global disease that affects a huge proportion of people around the world especially in the Middle East, where multiple allergy-promoting factors can be found. Although AR is not fatal, it severely affects the quality of life. However, it is usually overlooked in developing countries due to resource scarcity.

METHODS

An online questionnaire on social media was used which included demographics, smoking, socioeconomic-status (SES), war-related questions, and the score for allergic rhinitis (SFAR), a simple self-reporting tool with the cut-off point at 7. Findings. This study included 968 subjects with 721 (74.5%) females. The mean age was 24.69 years with AR prevalence at 47.9%. AR was associated with male gender [P = 0.001 (OR, 1.677; 95% CI 1.249-2.253)], having a job [P = 0.049 (OR, 1.309; 95% CI 1.001-1.713)], the having a chronic medical condition (P < 0.0001) mainly other allergies [P < 0.0001 (OR, 9.199; 95% CI 3.836-22.063)] and asthma [P = 0.006 (OR, 5.060; 95% CI 1.396-18.342)], using medications (P < 0.0001) and living in particular provinces (P = 0.010). However, no significant correlation was found with type of work and war factors except being distressed by war sounds [P = 0.027 (OR, 1.348; 95% CI 1.034-1.757)]. Finally, no associations were found with age, consanguinity, SES, educational level, and cigarette or/and shisha smoking (P > 0.05). Interpretation. Approximately half of the sample displayed AR symptoms, indicating a potentially high burden of AR in the community. A correlation to being distressed from war noises was found with AR which could reflect a psychological aspect. In addition, in war harmful allergens are released which can be an additional AR risk factor which adds to the environment in the Middle East that is associated with AR. However, we need further studies to discover and minimize this huge prevalence of AR.

Cumulative Evidence for Association of Acetaminophen Exposure and Allergic Rhinitis

BACKGROUND

Several studies have linked acetaminophen exposure to the risk of allergic rhinitis, with controversial results.

METHODS

A systematic search of PubMed, Embase, Cochrane Library, and Web of Science was conducted up to December 1, 2019. We included observational studies that examined the association between acetaminophen exposure and the risk of allergic rhinitis. Two reviewers independently extracted data and assessed study quality. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects meta-analysis.

RESULTS

Eighteen studies with 870,492 participants were included. Analysis showed that acetaminophen exposure was associated with an increased risk of allergic rhinitis (OR: 1.54, 95% CI: 1.41-1.69). Also, early exposure and exposure in the past year to acetaminophen was positively associated with risk of allergic rhinitis (OR: 1.34, 95% CI: 1.21-1.49 and OR: 1.74, 95% CI: 1.48-2.04, respectively). The risk of allergic rhinitis was greater for people who had acetaminophen exposure once per month over the past year (OR: 1.90, 95% CI: 1.60-2.26) compared to once per year (OR: 1.28, 95% CI: 1.11-1.48).

CONCLUSION

With our meta-analysis, we provide the evidence that exposure to acetaminophen is associated with an increased risk of allergic rhinitis. In addition, acetaminophen exposure in early life and acetaminophen exposure in the past year are positively associated with the risk of allergic rhinitis. Future research is needed to evaluate whether the association is causal.

Efficacy of acupuncture at three nasal acupoints plus acupoint application for perennial allergic rhinitis: A multicenter, randomized controlled trial protocol

BACKGROUND

Many studies have shown the potential therapeutic effect of acupuncture on allergic rhinitis. Most of these studies were limited by low-quality evidence. Preliminary experiments showed that the use of acupuncture at three nasal acupoints plus acupoint application (AAP) achieves a more persistent effect in the treatment of perennial allergic rhinitis than acupuncture alone. In this study, a multicenter, single-blind, randomized controlled trial will be performed, in which acupuncture at nonmeridian acupoints and sham AAP will be used as the control group to evaluate the effect of AAP through long-term observation.

METHODS

The trial is designed on the basis of the Consolidated Standards of Reporting Trials 2010 guidelines and Standards for Reporting Interventions in Controlled Trials of Acupuncture. A total of 120 participants with perennial allergic rhinitis will be randomly assigned to a treatment or control group. A specially appointed investigator will be in charge of randomization. The participants in the treatment group will be treated with acupuncture at EX-HN3, LI20, and EX-HN8 thrice per week for a total of 12 sessions. In addition, they will undergo AAP at DU14, BL13, EX-BI, and RN22. The participants in the control group will be treated with sham AAP. The primary outcome will be the change in the Total Nasal Symptom Score from baseline to the completion of 4-week treatment. Secondary outcomes include changes in visual analog scale and total non-nasal symptom scores from baseline to the second and fourth weeks of treatment, as well as 1, 3, and 6 months after the completion of treatment. Peripheral blood IL-4, IL-5, IL-6, IL-8, and IL-10 levels will be measured, and any side effects related to treatment will be observed and recorded.

DISCUSSION

It is expected that this randomized clinical trial will provide evidence to determine the effects of AAP compared with acupuncture at nonmeridian acupoints and sham AAP, particularly the long-term effect. These findings will help improve the clinical application of this technique.

Allergy and related clinical symptoms among medical students and interns

OBJECTIVES

To determine the prevalence, types, clinical presentations, triggers, and predictors of allergic disorders among medical students and interns at King Abdulaziz University (KAU), Jeddah, Saudi Arabia.

METHODS

A cross-sectional design was used for this study in which 600 medical students and interns were selected by a multistage stratified random sampling. A validated, confidential, self-administered questionnaire was used during 2016 / 2017. It asked about the previous diagnosis of allergic disorders, associated factors, types, clinical symptoms and the triggering allergenic. Descriptive & inferential statistics were done and logistic regression analysis was conducted.

RESULTS

The overall prevalence of diagnosed allergic disorder(s) among the participants was 36.2%.The commonest types of allergy were skin (33.8%) followed by respiratory (29.5%) presentations. The most frequently reported allergenic triggers were the house dust (45.6%) and smoke (30.4%). The first allergy predictor was family history of allergic disorders (aOR= 4.35, 95 % CI: 2.96-6.39), followed by female gender. Regarding the outcome of allergy on students' life, 16.1% occasionally missed classes, and 28.6% had sleep disturbance during allergic attacks.

CONCLUSION

Allergy represents an important problem among medical students and interns. Family history and female gender were the predictors of allergy. Skin and respiratory allergies were the most common types. House dust and smoke were the commonest allergenic triggers. Detection of allergens and management of cases of allergy among medical students and interns are needed. Education and conduction of awareness campaigns about allergy are needed.

Assessment of Allergic Rhinitis among Children after Low-Level Laser Therapy

BACKGROUND

Allergic rhinitis (AR) represents one of the most common global health problems with seriously increasing incidence over the last decades. The goal of the treatment of rhinitis is to prevent or reduce the symptoms caused by the inflammation of affected tissues. Intranasal steroids and oral antihistamines are recommended as first lines of treatment. Acupuncture had reported a significant improvement in daily symptoms and an increase of symptom-free days in many studies enrolling adults' patients.

AIM

This study aimed to evaluate the laser acupuncture effect on the treatment of children AR in comparison to the effect of the medication and to assess the anti-inflammatory effect of laser acupuncture through measurement of serum inflammatory marker (hs-CRP).

METHODS

Sixty patients with allergic rhinitis their age group ranged from 4 to 18 years were divided randomly into two groups. Group 1 enrolled 30 patient that received AR in the form of intranasal steroids, antihistaminic, leukotriene antagonists while group2 thirty patients received 12 laser acupuncture sessions (2 sessions a \ week) on specific traditional Chinese acupuncture points.

RESULTS

There was a significant improvement in the severity score symptoms in both groups through and by the end of the study. High Significant improvement in the levels of the inflammatory marker in both groups, especially in the group which receive laser acupuncture sessions.

CONCLUSION

Laser acupuncture is a reliable, painless and non-invasive successful technique, which may be used as a complementary treatment for pediatric allergic rhinitis.

Allergic rhinitis: Disease characteristics and coping measures in Saudi Arabia

BACKGROUND

Despite allergic rhinitis (AR) being a highly prevalent disease, according to literature, it is often underdiagnosed or undertreated.

AIM

This study explored the disease characteristics of AR in the Saudi community and the non-conventional coping measures used to alleviate symptoms.

METHODS

The study was a nationwide cross-sectional study, using a self-report electronic survey distributed via social media networks in 2018. The survey included an explanatory letter and consent. The sample size comprised 3,458 participants and 2,849 adults had at least one of the four signs of AR, i.e. watery-nose, sneezing, nasal obstruction, itchy nose, watery eyes, in the past year, not related to cold/flu. The outcomes of the study were the triggers, pattern, severity and the classification of AR (2016 ARIA guidelines) and coping measures. Descriptive statistics, univariate analytic statistics and binary logistic regression analyses were conducted. The P-value was considered statistically significant at <0.05.

RESULTS

The leading reported trigger of AR was dust (74%, n = 2118), followed by pollen (17%, n = 477), mold (5%, n = 140) and fur (4%, n = 114). The prevalence of intermittent AR was (54%, n = 1,635), while that of persistent AR was (46%, n = 1,314). Almost one-third (34%, n = 959) complained of mild forms of AR, while others complained of moderate to severe forms (66%, n = 1890). The coping measures were mainly shower/humidification 368(12.9%) and herbal hot drinks 266(9.3%). Older participants (adj.OR = 1.3[1.1-1.5]) and overweight participants, (adj.OR = 1.2[1.1-1.4]) reported more persistent forms of rhinitis compared to their counter groups, (adj.P<0.001 and adj.P = 0.032) respectively. Female participants (adj.OR = 0.8[0.7-0.9]) had significantly milder forms of AR, in comparison to males, adj.P = 0.006.

CONCLUSION

This study presented the disease characteristics of self-reported AR and its associated factors in Saudi Arabia. Special attention should be paid to older age groups and overweight patients who reported persistent forms of AR. Males reported more severe and persistent forms of AR.

The clinical burden of allergic rhinitis in five Middle Eastern countries: results of the SNAPSHOT program

Background

The SNAPSHOT program provides current data on the allergic rhinitis burden in the adult general population of five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia and the United Arab Emirates, the latter three grouped into a Gulf cluster).

Methods

A multi-country, cross-sectional, epidemiological program conducted by telephone in a random sample of the adult general population; quotas were defined per country demographics. Subjects were screened for allergic rhinitis using the Score For Allergic Rhinitis questionnaire. Current prevalence (last 12 months) was estimated. Disease severity and control were assessed using the Allergic Rhinitis and its Impact on Asthma classification and Rhinitis Control Assessment Test respectively. Quality of sleep, impact on daily activities and quality of life were measured using the Epworth Sleepiness Scale, Sheehan Disability Scale and EuroQol Five-Dimension questionnaire respectively. Multivariate logistic regression analyses were used to investigate risk factors and co-morbidities.

Results

1808 of 33,486 subjects enrolled in the SNAPSHOT program fulfilled the case definition for allergic rhinitis. Prevalence was 3.6% [95% CI 3.2–4.0%] in Egypt, 6.4% [95% CI 5.9–6.9%] in Turkey and 6.4% [95% CI 6.0–6.9%] in the Gulf cluster. Risk factors identified were country, co-morbid asthma and income. Subjects with allergic rhinitis reported a significantly lower quality of life compared to the general population (p < 0.0001). Overall, 55% of allergic rhinitis subjects were moderate/severe and 33% were uncontrolled. Both these groups reported impaired quality of life and quality of sleep and increased impairment of daily activities compared to mild/well-controlled subjects (p < 0.0001).

Conclusions

Although the observed prevalence of allergic rhinitis in these Middle Eastern countries is low compared to western countries, its burden is considerable. Allergic rhinitis in general, and specifically uncontrolled and severe disease, results in a negative impact on quality of life, quality of sleep and daily activities.

Correlation between Allergic Rhinitis and Laryngopharyngeal Reflux

Background and Objectives

Laryngopharyngeal reflux (LPR) exhibits nonspecific clinical presentations, and these symptoms may be associated with other conditions such as allergies, including allergic rhinitis and laryngitis. However, there is a gap in the literature regarding the correlation of laryngopharyngeal reflux with allergic rhinitis/laryngitis. Hence, the aim of this study is to explore the correlation between these two conditions.

Patients and Methods

A total of 126 patients with suggestive manifestations of laryngopharyngeal reflux were included in this study. Patients were classified into LPR positive and negative groups based on the results of a 24-hour oropharyngeal pH monitoring system while allergic rhinitis status was assessed with the score for allergic rhinitis (SFAR).

The results of the two groups were compared regarding the SFAR score. Correlation between the pH results and SFAR score was explored. Results

The LPR positive group demonstrated significantly higher SFAR scores compared to the negative LPR group (p < 0.0001). In addition, the Ryan score was significantly correlated with the SFAR total score and its symptomatology-related items (r ranged between 0.35 and 0.5). Conclusion. It seems that laryngopharyngeal reflux increases patients' self-rating of allergic manifestations. It appears that there is an association between laryngopharyngeal reflux and allergic rhinitis/laryngitis.

Validation of the Arabic version of the score for allergic rhinitis tool

BACKGROUND

Allergic rhinitis (AR) is a common inflammation of the nasal mucosa in response to allergen exposure. We translated and validated the Score for Allergic Rhinitis (SFAR) into an Arabic version so that the disease can be studied in an Arabic population.

OBJECTIVES

SFAR is a non-invasive self-administered tool that evaluates eight items related to AR. This study aimed to translate and culturally adapt the SFAR questionnaire into Arabic, and assess the validity, consistency, and reliability of the translated version in an Arabic-speaking population of patients with suspected AR.

STUDY DESIGN

Cross-sectional.

SETTING

Tertiary care hospital in Riyadh.

PARTICIPANTS AND METHODS

The Arabic version of the SFAR was administered to patients with suspected AR and control participants.

MAIN OUTCOME MEASURE

Comparison of the AR and control groups to determine the test-retest reliability and internal consistency of the instrument.

RESULTS

The AR (n=173) and control (n=75) groups had significantly different Arabic SFAR scores (P < .0001). The instrument provided satisfactory internal consistency (Cronbach's alpha value of 0.7). The test-retest reliability was excellent for the total Arabic SFAR score (r =0.836, P < .0001).

CONCLUSION

These findings demonstrate that the Arabic version of the SFAR is a valid tool that can be used to screen Arabic speakers with suspected AR.

LIMITATIONS

The absence of objective allergy testing.

Mental Health in Allergic Rhinitis: Depression and Suicidal Behavior

A high proportion of suicides visit their medical provider in the month prior to death, but depression, suicidal thoughts, and substance use are seldom addressed. For the clinicians routinely treating a substantial patient population with allergic diseases, there are additional concerns, as allergy has been linked with both depression and suicidal behavior. While psychotropic medications may affect diagnosis of allergies, medications used to treat allergies impact mood and behavior. Thus, we present an overview of the overlap of allergic rhinitis with depression and suicidal behavior in adults, based on clinical and epidemiological data, and our research and clinical experience. In summary, we suggest: 1) inquiring among patients with allergies about personal and family history of depression, substance use disorders, suicidal ideation and attempts 2) increased mindfulness regarding the potential effects of allergy medications on mood and behavior; and 3) for people identified with certain types of depression or increased suicide risk, a systematic multilevel collaborative approach. While for practical reasons the majority of patients with depression will continue to be treated by general or family practitioners, the allergy-treating provider should always consider integrated care for bipolar, psychotic or suicidal depression and incomplete remission, or relapsing and highly recurrent course. While awaiting results of much needed basic and clinical research to guide clinical approach for patients with comorbid allergic rhinitis and depression, the simple steps recommended here are expected to improved clinical outcomes in depression, including, on a large scale, reduced premature deaths by suicide.

Concealing Emotions at Work Is Associated with Allergic Rhinitis in Korea

Concealing emotions at work can cause considerable psychological stress. While there is extensive research on the adverse health effects of concealing emotions and the association between allergic diseases and stress, research has not yet investigated whether concealing emotions at work is associated with allergic rhinitis. Allergic rhinitis is a common disease in many industrialized countries, and its prevalence is increasing. Thus, our aim was to determine the strength of this association using data from three years (2007-2009) of the 4th Korean National Health and Nutrition Examination Survey. Participants (aged 20-64) were 8,345 individuals who were economically active and who had completed the questionnaire items on concealing emotions at work. Odds ratio (OR) and 95% confidence intervals (95% CIs) were calculated for allergic rhinitis using logistic regression models. Among all participants, 3,140 subjects (37.6%) reported concealing their emotions at work: 1,661 men and 1,479 women. The OR (95% CIs) for allergic rhinitis among those who concealed emotions at work versus those who did not was 1.318 (1.148-1.512). Stratified by sex, the OR (95% CIs) was 1.307 (1.078-1.585) among men and 1.346 (1.105-1.639) among women. Thus, individuals who concealed their emotions at work were significantly more likely to have a diagnosis of AR in comparison to those who did not. Because concealing emotions at work has adverse health effects, labor policies that aim to reduce this practice are needed.

The prevalence of allergic rhinitis and atopic markers in obstructive sleep apnea

Allergic rhinitis (AR) related inflammation might worsen the severity of obstructive sleep apnea (OSA), however, the relationship between the two disorders remains controversial. Our aim was to determine the prevalence of AR and atopic markers in OSA. This cross-sectional study recruited participants with sleep-related complaints referred to a sleep center from February 2013 to June 2014. The diagnosis of OSA was based on the Berlin questionnaire (BQ) followed by confirmatory polysomnography (PSG). The diagnosis of AR was made via focused history and clinical examination and was confirmed by measuring atopic markers. OSA was diagnosed in 97 out of 157 adults attending the sleep clinic (61.8%). There was a high prevalence of AR (52.6%) among OSA individuals. This was not significantly different from the frequency in the non-OSA individuals (p = 0.5). Elevated total immunoglobulin E (IgE; >100 K/μL), eosinophil count, and positive Phadiatop tests were found in individuals with OSA to be 37.1%, 11.3%, and 41.2%, respectively. Individuals without OSA have shown similar percentages. In our cohort, there was no significant difference in frequency of AR and atopy among participants with OSA compared to those without OSA.

Prevalence and triggers of allergic rhinitis in the United Arab Emirates

BACKGROUND AND OBJECTIVES

Allergic rhinitis is a morbid condition that is frequently overlooked by patients and physicians. This type of atopy has not been adequately investigated in the United Arab Emirates.

METHODS

This cross-sectional, population-based observational study was conducted in the seven Emirates (Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al-Quwain, Ras Al-Khaimah, and Fujairah). It used the European Community Respiratory Health Survey (ECRHS II) to screen for allergic rhinitis in people living in this region.

RESULTS

Symptoms of allergic rhinitis were present in 85 (7%) of the 1,229 study population. Only 33 (39%) patients received treatment. Seventy-six (89%) patients had asthma. Thirty-seven (44%) patients were poly-sensitized. Symptoms were aggravated by dust (59%), grass/pollens (44%) and proximity to animals (21%). Winter was the peak season (37%), followed by spring (30%), autumn (18%) and summer (15%). Grass/pollen allergies were clustered in the winter, spring and summer (p ≤ 0.001). Dust was non-seasonal (p ≥ 0.121) and animal allergy was worse in the winter (p = 0.024) and spring (p = 0.044). Spring symptoms were less common in people living in the inner city (p = 0.003).

CONCLUSIONS

At least 7% of the studied population had allergic rhinitis. Most (71%) of these patients had environmental triggers and remained untreated. Allergic rhinitis awareness and measures to control allergens and dust are needed. The impact of preventing allergic rhinitis on other common atopies in the region deserves future studies.

Chapter 15: Allergic rhinitis

Allergic rhinitis affects 60 million of the U.S. population, 1.4 billion of the global population, and its prevalence appears to be increasing. The duration and severity of allergic rhinitis symptoms place a substantial burden on patient's quality of life, sleep, work productivity, and activity. The health impact of allergic rhinitis is compounded by associated complications and comorbidities including asthma, otitis media, sinusitis, and nasal polyps. Allergic rhinitis symptoms result from a complex, allergen-driven mucosal inflammatory process, modulated by immunoglobulin E (IgE), and caused by interplay between resident and infiltrating inflammatory cells and a number of vasoactive and proinflammatory mediators, including cytokines. This allergic response may be characterized as three phases: IgE sensitization, allergen challenge, and elicitation of symptoms. A thorough allergic history is the best tool for the diagnosis of allergic rhinitis, the establishment of which is achieved by correlating the patient's history and physical exam with an assessment for the presence of specific IgE antibodies to relevant aeroallergens determined by skin testing or by in vitro assay. Management of allergic rhinitis includes modifying environmental exposures, implementing pharmacotherapy, and, in select cases, administering allergen-specific immunotherapy. Intranasal therapeutic options include antihistamines, anticholinergic agents, corticosteroids (aqueous or aerosol), mast cell stabilizers, saline, and brief courses of decongestants. Selection of pharmacotherapy is based on the severity and chronicity of symptoms with the most effective medications being intranasal corticosteroids and intranasal antihistamines, which can be used in combination (separately or in fixed dose) for more difficult to control allergic rhinitis.

The impact and treatment of allergic rhinitis in the Middle East: a comparison with the landmark allergy surveys from other worldwide regions

BACKGROUND

Allergic rhinitis is a global health problem that significantly affects quality of life. It is associated with illness, disability, health care costs, and comorbidities such as asthma.

METHODS

Between 2006 and 2011, a series of patient surveys were conducted covering the United States, Asia-Pacific, Latin America, and the Middle East. This article compares data regarding disease burden, treatment patterns, and patient expectations in Middle Eastern countries with those from other regions.

RESULTS

The surveys highlighted the relatively low use of intranasal corticosteroids (INCSs), the current "gold standard" treatment for allergic rhinitis. This may be because of side effects, lack of efficacy, or reduced effectiveness over time. A higher proportion of patients in the Middle East reported bothersome side effects of their prescription nasal sprays, and a higher proportion of these patients strongly agreed that there were no truly effective treatments for allergic rhinitis. This suggests that health care practitioners in the Middle East should be encouraged to explain the use of INCSs in greater depth to their patients.

CONCLUSION

There remains an unmet need in the treatment of nasal allergies worldwide. The allergy surveys highlight the key factors in choosing an INCS: fast, complete, and long-lasting symptom relief. There is opportunity for novel INCS treatments that address these needs while reducing troublesome side effects. Patient education must play a central role in treatment decision making, particularly in the Middle East, to achieve higher patient satisfaction.
