A nationwide study of asthma correlates among adolescents in Saudi Arabia

The Saudi initiative for asthma - 2024 update: Guidelines for the diagnosis and management of asthma in adults and children

The Saudi Initiative for Asthma 2024 (SINA-2024) is the sixth version of asthma guidelines for the diagnosis and management of asthma for adults and children that was developed by the SINA group, a subsidiary of the Saudi Thoracic Society. The main objective of the SINA is to have guidelines that are up-to-date, simple to understand, and easy to use by healthcare workers dealing with asthma patients. To facilitate achieving the goals of asthma management, the SINA Panel approach is mainly based on the assessment of symptom control and risk for both adults and children. The approach to asthma management is aligned for age groups: adults, adolescents, children aged 5-12 years, and children aged <5 years. SINA guidelines have focused more on personalized approaches reflecting a better understanding of disease heterogeneity with the integration of recommendations related to biologic agents, evidence-based updates on treatment, and the role of immunotherapy in management. The medication appendix has also been updated with the addition of recent evidence, new indications for existing medication, and new medications. The guidelines are constructed based on the available evidence, local literature, and the current situation at national and regional levels. There is also an emphasis on patient-doctor partnership in the management that also includes a self-management plan.

Lifetime prevalence and treatment of mental disorders in Saudi youth and adolescents

Previous global and regional studies indicate that adolescents and young adults (i.e., youth) are affected by various mental disorders with lifelong consequences. However, there are no national estimates of mental disorders prevalent among Saudi youth. Using data from the Saudi National Mental Health Survey (SNMHS), we examined the lifetime prevalence, treatment, and socio-demographic correlates of mental disorders among Saudi youth (aged 15-30). A total of 4004 interviews were conducted using the adapted Composite International Diagnostic Interview (CIDI 3.0). Cross tabulations and logistic regression were used to generate estimates for the SNMHS youth sample (n = 1881). The prevalence of a mental disorder among Saudi youth was 40.10%, where anxiety disorders affected 26.84% of the sample, followed by disruptive behavior disorders (15.44%), mood disorders (9.67%), substance use disorders (4%) and eating disorders (7.06%). Sex, education, parental education, income, marital status, region, and family history of disorders were significant correlates of various classes of mental disorders. Only 14.47% of Saudi youth with any mental disorder received treatment for a lifetime disorder. Age, parental education, and family history of disorders emerged as significant correlates of mental health treatment. Lifetime mental disorders are highly prevalent among Saudi youth. There is an unmet need for culturally sensitive and age-appropriate treatment of lifetime mental disorders among youth in Saudi Arabia.

Sociodemographic Characteristics, Dietary Intake, and Body Image Dissatisfaction Among Saudi Adolescent Girls

This study assesses sociodemographic characteristics, dietary intake and body image dissatisfaction (BID) among Saudi adolescent girls. A total of 399 girls ages 13-14 were randomly selected from intermediate schools in Arar, Saudi Arabia. Data on anthropometric measurements, sociodemographic characteristics, dietary intake and body image (BI) were collected. Multiple linear regression was used to predict the association between variables. Most adolescents had a normal weight based on their body mass index (BMI), normal waist circumference (WC), and normal waist-to-height ratio (WHtR). Fried chicken and Kabsa rice were the most frequently consumed foods; most girls consumed excessive fat. Most girls had BID (81.5%), and 51.4% desired to lose weight. BMI was positively correlated with age and current BI (p<0.001) and negatively associated with dairy product intake (p=0.004) and desired BI (p<0.001). WC had a positive association with age (p=0.001) and current BI (p<0.001) and a negative association with dairy product intake, cereal and grain intake (p=0.001) and ideal BI (p<0.001). WHtR was positively associated with current BI (p<0.001) and negatively associated with cereal and grain intake (p=0.005), dairy product intake and desired BI (p<0.001). Although most participants had a normal weight, they consumed excessive fat and were dissatisfied with their BI, which are significant predictors of obesity. Saudi adolescent girls require nutritional interventions to help them transition to a healthy diet, positive BI and healthy lifestyle.

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.

Asthma patients in Saudi Arabia - preferences, health beliefs and experiences that shape asthma management

Objectives: The aim of this study was to explore the experience of Saudi participants in managing their asthma and their perspectives about using future pharmacy-based services for asthma management.

METHODS

Semi-structured interviews were conducted with adult Saudis with asthma or those who were a carer of a child with asthma. Participants were recruited from medical practices and community centres in Riyadh, Saudi Arabia. Verbatim transcribed interviews were inductively analysed using thematic analysis.

RESULTS

Twenty-three Saudi participants with asthma or caring for those with asthma took part in interviews which lasted on average for 25 min. Most participants did not have well-controlled asthma. Thematic analyses of the interview transcripts highlighted four key emergent themes: participants experience of asthma, participants' beliefs and perceptions about health and medicines, perception of health professionals and advocacy and social support. Many participants expressed an emotional burden in their lived experience of asthma. Lack of self-management skills were evident in participants' reluctance to make decisions in emergency situations. Some participants had strong beliefs about using herbal medicines rather than western medicines. Using social media or consulting with their family members with asthma was a common preference, rather than consulting healthcare professionals. Participants' were rather unclear about pharmacy asthma care services and reported not having experienced such services in their pharmacies.

CONCLUSION

Inadequate self-management behaviours may affect the level of asthma control in people with asthma in Saudi Arabia. Improved primary care models with extensive focus on asthma education are needed to relieve the over-reliance on tertiary care help-seeking models that are currently the norm. Current evidence-based information also needs to be prepared in patient friendly formats and disseminated widely. Community pharmacists would need to be trained and skilled inpatient engagement and would have to win the public trust for viable asthma services provision.

Investigating the Outcomes of an Asthma Educational Program and Useful Influence in Public Policy

The study was conducted to evaluate the effectiveness of an asthma educational program for asthma control, asthma self-management, asthma knowledge, and patient activation. The study analyzes different demographic variables with the purpose of investigating which asthma patients performed better than others. Based on these demographic characteristics, the study provides several recommendations for various stakeholders. The study is based on a positivist approach since its purpose is to investigate the consequences of an asthma educational program with a view to generalizing the results to a larger population. The study targets public and private hospitals which have applied the asthma educational program in collaboration with the Saudi Initiative for Asthma (SINA). Multiple questionnaires were deployed 263 valid responses were received from patients of public and private hospitals using online and offline data collection method. Several parametric and non-parametric tests were carried out in terms of data analysis. The results reveal that patients in the intervention group obtained high scores and were therefore more knowledgeable and able to control their asthma compared to the control group. Overall, patients in the intervention group performed better in terms of asthma control, asthma self-management and knowledge and awareness. There was a high level of patient activation in this group. In the context of demographic features, it was found that patients who are married and are undergraduate degree holders in employment scored high compared to patients who were young, single, post-graduate degree holders that were mainly self-employed. The results of this study can guide policy makers, SINA authorities, and hospitals as to which demographic category of asthma patients require immediate attention. The significance of asthma educational programmes has increased especially through social media platforms as the number of adult patients continues to increase day by day.

Plasma levels of BAFF and APRIL are elevated in patients with asthma in Saudi Arabia

B-cell activation factor (BAFF) and a proliferation-inducing ligand (APRIL) are members of the tumor necrosis factor superfamily of cytokines and can induce B cell activation, differentiation, and antibody production via interaction with their receptors, including transmembrane activator, calcium modulator, and cyclophilin ligand interactor (TACI), B-cell maturation antigen (BCMA), and B-cell activating factor receptor (BAFF-R). Herein, we assessed the plasma protein levels of BAFF and APRIL in patients with asthma to determine whether their expression is correlated with total IgE production and examined the surface expression of BAFF/APRIL receptors on B cells. Blood samples were collected from 47 patients with controlled asthma symptoms and 20 healthy normal controls, and plasma levels of APRIL, BAFF, and total IgE protein were quantified by corresponding ELISA assays. Furthermore, lymphocytes were isolated and B cells were analyzed for the presence of BAFF-R, BCMA, and TACI receptors using flow cytometry. Our results showed that IgE, BAFF, and APRIL plasma levels were markedly increased in patients with asthma compared with healthy controls. Moreover, expression of BAFF-R and BCMA, but not that of TACI, was significantly increased in patients with asthma compared with healthy controls. Overall, the findings suggest BAFF and APRIL as key mediators of asthma, and determination of their plasma levels may be useful in monitoring asthma symptoms and treatment response.

Knowledge and perception about asthma among students in a Nigerian single-sex secondary school

INTRODUCTION

Asthma is prevalent among children and adolescents. Few studies have assessed the knowledge and perceptions of asthma among adolescents.

OBJECTIVES

This study assessed the knowledge and perception about asthma among secondary school students in an all-girls school in Nigeria.

METHODS

This cross-sectional study was conducted in a Nigerian secondary school in Enugu State (February 2020). In Senior Secondary School (SS1, SS2 and SS3), students could be in one of three specialized classes: Sciences, Humanities and Business. A self-administered structured questionnaire was filled by conveniently sampled students in SS1 and SS2. Inferential statistics utilized the Pearson's chi-square test and multiple linear regression with statistical significance set as P < 0.05.

RESULTS

Three hundred and eighty-eight (388) students participated in the study (mean age = 14.64 ± 0.93 years). Majority of the students were in Science class (n = 299; 77.1%). There was high awareness about asthma (n = 384; 99.0%). More than half of them had good asthma knowledge (n = 279; 71.9%); close to three-fifths had favourable perception of asthma (n = 222; 57.2%). More students in SS2 had good knowledge of asthma compared to those in SS1 (76.7% vs. 67.2%; ꭓ²  = 4.338; P = 0.037). More students in Science class had favourable perceptions about asthma compared with those in Humanities and Business class (60.5% vs. 48.1% vs. 25.0%; ꭓ²  = 7.458; P = 0.024).

CONCLUSION

Majority of the students were aware about asthma and had good knowledge of the disease while close to three-fifths had favourable perceptions about asthma.

Prevalence and associated factors of respiratory allergies in the Kingdom of Saudi Arabia: A cross-sectional investigation, September-December 2020

Background

Prevalence of different respiratory allergies is increasing in the Kingdom of Saudi Arabia (KSA). Environmental risk factors of respiratory allergy vary regionally, hence the prevalence. This necessitates the needs for regional studies. This article reports prevalence and symptoms of respiratory allergies in the Qassim region, and the factors associated with the prevalence.

Methods

Eight hundred and fifty individuals aged ≥18 years and were living in the Qassim region filled up our structured online questionnaire between September and December 2020. We estimated the prevalence of different respiratory allergies with 95% confidence intervals. Multi-variable logistic regression analyses were performed to investigate the risk factors of respiratory allergies.

Findings

The prevalence of any respiratory allergy in the Qassim region was 28.8%. Most families (58.1%) had at least one member with respiratory allergy. The prevalence of allergic rhinitis and bronchial asthma were 13.5% and 11.2% 4.1% respectively. The reported symptoms included runny nose (13.6%), red, watery, and itchy eyes (10.4%), difficulty sleeping at night (10.2%), difficulty breathing in cold weather (9.2%), noisy breathing (8.5%), sneezing (8%), repeated coughing (7.5%) and shortness of breath (6.4%). Individuals with a family history were more likely to report any respiratory allergy (OR: 7.8), bronchial asthma (OR: 4.2) and allergic rhinitis (OR: 8.1) compared to the individuals without such family history. Odds of respiratory allergies was higher among males (OR: 1.5). Saudi nationals were less likely to report allergic rhinitis than the non-Saudis (OR: 0.4). Among those who reported a respiratory allergy, most (73.5%) received treatment and majority (61.7%) demonstrated compliance to the treatment, 8.8% needed hospitalization, and 23.1% needed emergency nebulization.

Conclusions

Prevalence reported in our study is different than that reported in other regions. Variability in the environmental exposures might explain this. We recommend a meta-analysis to estimate the national prevalence of respiratory allergies.

IL-35 and IL-37 are negatively correlated with high IgE production among children with asthma in Saudi Arabia

BACKGROUND

Asthma is one of the most prevalent inflammatory disorders among children in Saudi Arabia.

OBJECTIVE

This study aimed to determine the correlation between the serum levels of vitamin D, immunoglobulin E (IgE), and cytokine (interferon-gamma (IFN-γ), interleukin (IL)-1β, IL-4, IL-6, IL-10, IL-13, IL-35, and IL-37) in relation to the severity of disease in patients with asthma.

METHODS

This case-control study was carried out at King Abdullah Specialist Children's Hospital, Saudi Arabia, and included 48 patients with asthma and 47 matched controls, aged 6-14 years. A validated questionnaire was administered to the participants, after which each patient with asthma underwent pulmonary function tests. The serum levels of vitamin D, IgE, IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-13, IL-35, and IL-37 of each participant were also measured.

RESULTS

Patients with asthma demonstrated significantly higher IgE and cytokine (IL-1β, IL-4, IL-6, IL-10, IL-13, IL-35, and IL-37) levels compared to the control group (p value < .001). The levels of IL-1β, IL-4, IL-10, and IL-13 were consistently positively correlated with the serum levels of IgE among patients with asthma. However, the IgE levels in patients with asthma were consistently negatively correlated with IL-35 and IL-37.

CONCLUSIONS

We found significantly higher levels of eosinophils, IgE, IL-1β, IL-4, IL-6, IL-10, IL-13, IL-35, and IL-37 in patients with asthma compared to the controls, but no relationship between vitamin D and asthma.

Potential impacts of Acu-TENS in the treatment of adolescents with moderate to severe bronchial asthma: A randomized clinical study

OBJECTIVE

The purpose of this study was to evaluate the efficacy of transcutaneous electrical nerve stimulation over the acupuncture points (Acu-TENS) on total serum immunoglobulin E (IgE_total), pulmonary function, and quality of life in adolescents with asthma.

METHODS

In a double-blind randomized clinical trial, 32 adolescents (age; 12-16 years) with asthma participated and were assigned randomly to receive either the breathing retraining program (control group) or the breathing retraining program plus Acu-TENS application (Acu-TENS group). Acu-TENS was applied for 40 min' day-after-day session for two successive months, with no side-effects reported. Serum IgE_total, pulmonary function [forced vital capacity (FVC), forced expiratory volume at one second (FEV₁), and FEV₁/FVC], and quality of life were evaluated pre- and post-treatment.

RESULTS

Serum IgE_total (P = 0.028, η_p² = 0.15), Pulmonary function [FVC (P = 0.043, η_p² = 0.13), FEV₁ (P = .046, η_p² = 0.12)], and quality of life (P < .001, η_p² = 0.17) increased significantly in the Acu-TENS group when compared to the control group.

CONCLUSION

This study demonstrates that the Acu-TENS is an impending asthma treatment that may be used to reinforce the immune system response, ameliorate lung function, and increase the quality of life in adolescents with asthma.

Asthma-associated risk for COVID-19 development

The newly described severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for a pandemic (coronavirus disease 2019 [COVID-19]). It is now well established that certain comorbidities define high-risk patients. They include hypertension, diabetes, and coronary artery disease. In contrast, the context with bronchial asthma is controversial and shows marked regional differences. Because asthma is the most prevalent chronic inflammatory lung disease worldwide and SARS-CoV-2 primarily affects the upper and lower airways leading to marked inflammation, the question arises about the possible clinical and pathophysiological association between asthma and SARS-CoV-2/COVID-19. Here, we analyze the global epidemiology of asthma among patients with COVID-19 and propose the concept that patients suffering from different asthma endotypes (type 2 asthma vs non-type 2 asthma) present with a different risk profile in terms of SARS-CoV-2 infection, development of COVID-19, and progression to severe COVID-19 outcomes. This concept may have important implications for future COVID-19 diagnostics and immune-based therapy developments.
