APPaRENT 3: Asthma Patients' and Physicians' Perspectives on the Burden and Management of Asthma in Seven Countries

INTRODUCTION

Asthma management is strongly dependent on physician and patient beliefs and perceptions about the disease and its long-term treatment. The APPaRENT 3 study was conducted to explore factors influencing treatment choice and to understand patients' and physicians' attitudes and perspectives on the use of controller inhalers in regular versus flexible dosing for asthma management.

METHODS

This cross-sectional survey of patients with asthma and treating physicians was conducted in seven countries: Indonesia, Malaysia, Philippines, Thailand, Vietnam (patient survey only), Saudi Arabia, and the United Arab Emirates. Assessment was carried out through an online/face-to-face questionnaire, where patients' viewpoints were focused on their attitudes and beliefs about asthma and treatment adherence, whereas physicians' viewpoints were gathered on their attitudes and beliefs about asthma management, knowledge of and adherence to asthma treatment guidelines, and asthma treatment regimens.

RESULTS

Overall, 1400 patients (mean age, 34 years) and 599 physicians (mean age, 43 years) were included in the survey. Physicians similarly prioritised symptom control (39%) and exacerbation reduction (40%) in moderate asthma, whereas patients prioritised symptom control (41%) over exacerbation reduction (22%). Although both groups (physicians, 86%; patients, 84%) perceived asthma as well-controlled, poor management was evident based on Asthma Control Test (ACT) scores (mean, 15.7; standard deviation, 4.14; 82% had an ACT score < 20) and high symptom burden (39% reported nighttime awakenings or early mornings ≥ 2 nights/week). Most patients (76%) with moderate asthma were prescribed regular dosing, with the most common treatment being inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) with as-needed inhaled short-acting β2-agonist (SABA; 20%). Among patients on maintenance and reliever therapy, 93% of patients received a separate inhaled reliever.

CONCLUSIONS

Despite high symptom burden, patients overestimated their level of asthma control. Physicians prioritised controlling symptoms and reducing exacerbations as treatment goals for moderate asthma, often prescribing regular dosing with ICS/LABA with as-needed inhaled SABA.

Asthma Treatment Outcome and Factors Associated with Uncontrolled Asthma Among Adult Patients with Asthma in Addis Ababa, Ethiopia

Background

Asthma is a major public health challenge in the world resulting in significant health and economic burden. The modifiable and non-modifiable risk factors could have considerable impact on asthma control and medical care.

Objective

This study is intended to evaluate the treatment outcome and identify risk factors for poor asthma control among patients with asthma in Addis Ababa, Ethiopia.

Methods

A multicentre cross-sectional study using interview and chart review was conducted among patients with asthma attending ambulatory care of two large public hospitals in Addis Ababa, Ethiopia, between March and June 2018. The Global Initiative for Asthma Guideline was used to determine treatment outcomes. The variables of interest were described using descriptive statistics such as frequencies, percentages, mean, and standard deviations. Multivariable logistic regression was used to determine factors associated with uncontrolled asthma. All statistical significance level was determined at p < 0.05.

Results

A total of 230 patients with asthma were interviewed. More than half (65.2%) of patients were females, and their mean age was 54 ± 15.1 years. Overall, 50.4% of the patients had uncontrolled asthma status. More than two number of trigger factors (AOR = 1.88; 95% CI: 1.09-2.01), cold weather (AOR = 2.11; 95% CI: 1.51-2.42), exacerbations of asthma in the last 12 months (AOR = 2.01; 95% CI: 1.39-2.32), moderate persistent asthma (AOR = 3.47; 95% CI: 1.75-5.13), severe persistent asthma (AOR = 2.90; 95% CI: 2.56-3.98), patients on Salbutamol puff with Beclomethasone (AOR = 2.92; 95% CI: 2.50-3.45) and patients on Salbutamol puff with Beclomethasone and Prednisolone (AOR = 5.76; 95% CI: 4.02-6.02) use were significantly associated with uncontrolled asthma.

Conclusion

More than half of patients with asthma had uncontrolled asthma treatment outcome. This indicates the need to give due attention to asthma patients with uncontrolled status, particularly to those with identified risk factors. Health care providers should work in creating patient awareness on appropriate use of their prescribed medications, avoidance of asthma triggering factors for decreasing the progression of the disease and better asthma control.

Adherence to medication among adult asthma patients in the Middle East and North Africa: results from the ESMAA study

BACKGROUND

Low levels of adherence to asthma medication is reported in many countries worldwide. Improved knowledge of adherence in the Middle East and North Africa (MENA) is needed to address this major public healthcare burden.

OBJECTIVE

Assess the level of adherence in patients attending a routine consultation and the relationship between adherence, patient/disease characteristics, disease control, and quality of life.

METHODS

A large-scale cross-sectional epidemiological study was performed on adults suffering from asthma for at least 1 year and without an acute asthma episode within 4 weeks. Adherence was assessed using the MMAS-4 questionnaire©. Predictive factors of adherence were analyzed with logistic regressions.

RESULTS

Overall 7203 eligible patients were included in 577 sites. Mean age was 45.4 years (±14.7), 57.2% were female, mean BMI was 28.5 kg/m2 (±6.0), and 11% were active smokers. Good adherence was observed in 23.6% with a country effect (p < 0.001). Higher age, higher SF-8 Mental component score, and high level of control were associated with good adherence (p < 0.001). Patients treated with a fixed combination (ICS + LABA) have better adherence and patients treated with short-acting beta agonist alone have a lower adherence. Good adherence has been noted in 528 uncontrolled patients suggesting the existence of a subgroup difficult to treat and who have severe asthma.

CONCLUSIONS

Asthma adherence in the MENA is unsatisfactory with less than one quarter of asthma patients having good adherence. This finding highlights the need to improve access to treatment, ensure better control follow-up and improved education among healthcare providers and patients.

[Asthma and obesity: relationship and therapeutic implications in patients with asthma at the Department of Pneumology in Monastir, Tunisia]

Introduction

L’obésité et l’asthme sont deux maladies chroniques touchant des millions d’individus à travers le monde. La présence d’un lien de causalité est suggérée. L'objectif de notre travail est d'étudier le profil de l’asthmatique obèse et de déterminer la relation entre les différents paramètres de sévérité de l’asthme avec les grades de l’obésité.

Méthodes

Il s'agit d'une étude rétrospective, monocentrique, analytique menée au Service de Pneumologie et d’Allergologie au CHU Fattouma Bourguiba de Monastir portant sur 450 asthmatiques, ayant un indice de masse corporelle (IMC) ≥ 30 kg/m² avec un recul d’au moins 6 mois.

Résultats

L’âge moyen au moment du diagnostic était de 45±12.8 ans. L’IMC moyen était de 34,8±4,2 kg/m². L’asthme était bien contrôlé chez 55,3% des patients. Des critères de sévérité étaient notés dans 37.4% des cas. Selon GINA 2016, 24,2% sont traités par le palier 4. Deux phénotypes de l’asthme associé à l’obésité étaient notés. Le premier phénotype (52,4%) était caractérisé par un asthme à début précoce, associé à une fréquence plus élevée d’allergie, et des manifestations d'atopie. Le deuxième (47,6 %) était caractérisé par un asthme à début tardif, fréquemment associé au sexe féminin et un taux plus élevé de comorbidités et d’hospitalisations. Les obèses de grade II et III avaient un déficit ventilatoire important (CVF: p = 0,002 et VEMS: p = 0,007).

Conclusion

L’obésité est l’un des facteurs clefs impliqués dans le mauvais contrôle de l’asthme. Sa prise en charge, qui n'est pas encore codifiée, doit être multidisciplinaire.

Prevalence of asthma among the adult general population of five Middle Eastern countries: results of the SNAPSHOT program

BACKGROUND

Asthma is a common chronic respiratory disease leading to morbidity, mortality and impaired quality of life worldwide. Information on asthma prevalence in the Middle East is fragmented and relatively out-dated. The SNAPSHOT program was conducted to obtain updated information.

METHODS

SNAPSHOT is a cross-sectional epidemiological program carried out in five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia, and the United Arab Emirates, the latter three grouped into a Gulf cluster) to collect data on asthma, allergic rhinitis, benign prostatic hyperplasia and bipolar disorder. The survey was carried out by telephone in a random sample of the adult general population with quotas defined according to country demographics. The analysis presented in this paper focuses on asthma. Subjects were screened for asthma based on criteria from the global Asthma Insights and Reality studies. Current prevalence (last 12 months) was estimated. Multivariate logistic regression analyses were used to investigate risk factors related to asthma and the association with allergic rhinitis and other co-morbidities. Quality of life was assessed using the three-level EQ-5D questionnaire.

RESULTS

2124 out of the 33,486 subjects enrolled in the SNAPSHOT program fulfilled the criteria for asthma. The adjusted prevalence of asthma ranged from 4.4% [95% CI: 4.0-4.8%] in Turkey, to 6.7% [95% CI: 6.2-7.2%] in Egypt and 7.6% [95% CI: 7.1-8.0%] in the Gulf cluster. Prevalence was higher (p < 0.0001) in women than men and increased with age (p < 0.0001). Co-morbidities occurred more frequently in asthma subjects compared to the non-asthma population (38% vs. 15% p < 0.0001). Subjects with asthma reported a lower (p < 0.0001) EQ-VAS score (68.2 ± 22.9) compared to the general population (78.1 ± 17.5). The risk factors associated with asthma were age, gender, country, and certain co-morbidities, namely respiratory, cardiovascular, gastrointestinal, nervous, and neurological diseases.

CONCLUSION

The observed adjusted prevalence of asthma in the Middle East ranges from 4.4% to 7.6%, which is comparatively lower than the reported prevalence in Europe and North America. Asthma has a negative impact on quality of life, and is associated with high levels of co-morbid diseases, indicating a need for physicians to check for co-morbidities and ensure they are managed correctly in all asthma patients.

Asthma control in adults in the Middle East and North Africa: Results from the ESMAA study

BACKGROUND

Low levels of asthma control are reported in many countries worldwide. Improved knowledge of asthma control in the Middle East and Africa and predictive factors is needed to address this major public healthcare burden.

OBJECTIVE

To assess the level of asthma control in patients attending a routine consultation for asthma in the Middle East and North Africa, and the relationship between level of control and patient and disease characteristics, adherence, and quality of life (QoL).

METHODS

A large-scale cross-sectional epidemiological study (ESMAA: Assessment of Asthma Control in Adult Asthma Population in the Middle East and North Africa) was performed in adults suffering from asthma for at least 1 year and without an acute asthma episode within 4 weeks. Asthma control was assessed per the 2012 GINA guidelines and the ACT questionnaire. QoL and adherence were assessed with the SF-8 and Morisky questionnaires respectively. Predictive factors of asthma control were analysed with univariate and multivariate logistic regressions analyses.

RESULTS

Overall 7236 eligible patients were included in 577 sites between June 2014 and December 2015 (median 10 patients/site). Mean age was 45 years (±14), 57% were female, mean BMI was 28.5 kg/m² (±6.0), and 11% were active smokers. Reliever medication was prescribed in 96% of patients with 65% having fixed-dose combined inhaled corticosteroid plus long-acting beta agonists. Good medication adherence was reported in 24% of patients. Among 7179 patients evaluable for GINA, asthma was controlled in 29.4% (95% CI, 28.4%-30.5%), partly controlled in 29.1% (95% CI, 28.1%-30.2%), and uncontrolled in 41.5% (95% CI, 40.3% to 42.6). The mean global ACT score was 17.8 (±5.0), with 16% of patients considering their asthma as controlled. Poor medication adherence, active smoking, absence of medical insurance, lower level of education, or diagnosis at least 5 years earlier were significantly associated with uncontrolled asthma in multivariate analyses (p < 0.001).

CONCLUSIONS

Asthma control in the Middle East and North Africa is unsatisfactory with less than one-third of asthma patients having controlled disease, highlighting the need to improve treatment access and medication adherence, along with better follow-up and education among healthcare providers and patients.

Critical appraisal of the clinical utility of sublingual immunotherapy in allergy

Since it was introduced by Noon in 1911, allergen-specific immunotherapy or desensitization has been widely prescribed in the management of allergic diseases. Aimed at the etiology, it represents the only effective treatment for allergy. The basic mechanisms of immunotherapy are becoming better understood and allow us to improve this technique in the future. The sublingual immunotherapy as an alternative to subcutaneous route has been widely studied. Several clinical trials confirmed that sublingual immunotherapy is efficient in reducing allergic respiratory symptoms. The sublingual immunotherapy reduces the risk of developing serious side effects due to desensitization. We performed a literature review in order to remind the mechanisms of action and to demonstrate efficacy and tolerability of the sublingual immunotherapy in the treatment of allergic rhinoconjunctivitis and asthma and its impact on the quality of life.

Secular trends in consultations for asthma in early childhood, the 16 administrative regions of Morocco, 2004-2012

Background

Little is known about asthma trend in Morocco, particularly in early childhood. Furthermore, when dealing with asthma related environmental risk factors in Morocco, decision-making focus is in one region R9, while 16 regions make up the country. This work aims at studying 9-year trends in consultations for asthma in under-5 children in the 16 individual regions with respect to area and age group.

Methods

Direct method use, based on the only available national data from the open access files of the ministry of health, standardizing data for three age groups (0–11 ; 12–23 and 24–59 months). We compared age-adjusted rates, stratified by area (urban and rural areas) within each region (Wilcoxon's signed ranks test), and between all regions emphasizing on R9. Secular trends are examined (Kendall's rank correlation test). We also compared directly standardized rates as a rate ratio for two study populations (that of R9 and any region with highest rates). We finally compared rates by age group in selected regions.

Results

Secular increase in prevalence rates was shown in both urban and rural Morocco, particularly in urban areas of R10, R14, R16 and R5, and in rural areas of R14 and R16. In urban area of R10 (the highest age-adjusted prevalence rates area) the rates showed secular increase from 6.82 at 95 % CI = [6.44 to 7.19] per 1000 childhood population in 2004 to 20.91 at 95 % CI = [20.26 to 21.56] per 1000 childhood population in 2012 (P = 0.001). Rates were higher in urban than rural Morocco, particularly in R8, R9, R10, R14, R15 ; R6 was an exception. Rates in R10 were 1.63 higher than that in R9 in 2004 and rose to be 2.55 higher in 2012 ; rates in urban area of R14, about 3 times lower than that in R9 in 2004, increased to be similar in 2012. The highest-prevalence age group varied according to region and area.

Discussion

The regions that worth decision making attention are the urban areas of R10 (the highest prevalence rates Moroccan area, showing continuous increase), of R9, of R14 and the rural area of R6. The rates in the urban area of R9 (a current continuous decision making focus) remained high but stable within the study period and less important than those in R10. Environmental factors (biological particules, non-biological particules or gazes) are suspected.The potential unavailability of treatment at regular basis at the primary health care centers may reduce frequency of consultations for asthma in early childhood : outpatients may consult only if asthma causes problems in an attempt to get free medicines ; chances of outpatients' follow-up by the primary health care center's physicians are therefore reduced and optimal asthma control is not achieved.

Conclusion

Social, health care policy and environmental factors, to which decision-making has to be responsive, are suspected to be affecting both frequency of and time secular trend in consultations for asthma in early childhood in Morocco.

Educational and decision-support tools for asthma-management guideline implementation

Many international and national asthma guidelines are now available in large parts of the world, but they are not yet implemented appropriately. There is a gap between scientific evidence-based medicine and real clinical practice. Implementation of guidelines is highly complex. Special strategies are needed to encourage guideline-based, high-quality care. It is important to understand the contents, the format, and the learning strategies which physicians prefer for the dissemination of guidelines. Physicians prefer more concise and immediately available guidelines that are practical to use. Thus, asthma guidelines should be disseminated as convenient and easily accessible tools. Various education programs and decision-support tools have been designed and applied to the clinical management of asthma to solve these challenging problems. Many of them have been shown to be effective at increasing physicians' knowledge and adherence to asthma guidelines and improving patients' clinical outcomes. These educational and decision-support tools are expected to contribute to a narrowing of the gap between asthma guidelines and practice/implementation of the guidelines.
