Assessment of predictors for acute asthma attack in asthmatic patients visiting an Ethiopian hospital: are the potential factors still a threat?
Sewunet Admasu Belachew Daniel Asfaw Erku, Dawit Kumilachew Yimenu and Begashaw Melaku Gebresillassie
Recurrent exacerbations in patients with moderate or severe asthma are the major causes of morbidity, mortality and medical expenditure. Identifying predictors of frequent asthma attack might offer the fertile ground of asthma management. However, systematic data on asthma management is scarce in Ethiopia.
The purpose of the present study was to determine predictors of acute asthma attack in patients with asthma attending emergency department of University of Gondar Comprehensive Specialized Hospital (UOGCSH) in Gondar, northwestern Ethiopia.
An institutional-based cross-sectional self-administered survey was conducted on 108 asthmatic patients who came to the emergency department of UOGCSH following acute asthma attack. Data were collected through interviewer administered questionnaire. Logistic regression was done to see the possible association of potential factors that may lead to asthma exacerbation.
About half of the respondents (51.9%) were female and one third of patients (38.9%) were within the age range of between 46 and 60 years. The leading potential predictor were frequent exposure to various ongoing allergen (68.5%) followed by revelation to occupational sensitizers (67.6%). Chronic sinusitis (AOR = 3.532, 95% CL = 1.116–11.178), obstructive sleep apnea (AOR = 3.425, 95% CL = 1.255–9.356) and psychological disfunctioning (3.689 (1.327–10.255)) were among the significantly associated factors of acute asthma exacerbation.
Now days, the backbone for long-term asthma management is to prevent exacerbations. Chronic sinusitis, obstructed sleep apnea and psychosocial dysfunction were originated to be considerably linked with repeated exacerbations of asthma. Among those significantly associated predictors, obstructed sleep apnea were the most prevalent one.

Asthma Research and Practice: Effect of adjusting the combination of budesonide/formoterol on the alleviation of asthma symptoms
The combination of budesonide + formoterol (BFC) offers the advantages of dose adjustment in a single inhaler according to asthma symptoms. We analyzed the relationship between asthma symptoms in terms of peak expiratory flow (PEF) and dose adjustment by the patient.
Twenty-eight patients with asthma who used BFC for alleviation of their symptoms (12 men, 16 women; 60 years old) were instructed that the inhaled BFC dose could be increased to a maximum of 8 inhalations per day according to symptom severity. Patients measured and recorded PEF every morning and evening in their asthma diary along with their symptoms and the dose of drugs taken.
Sixteen of the 28 patients increased their dose for asthma symptoms. The time to recovery from the asthma symptoms was significantly shorter when cough was the only symptom present compared with dyspnea or wheeze (1.4 vs. 5.3 or 6.6 days, p < 0.05) and when they had only one symptom compared with two or three symptoms (1.3 vs. 5.7 or 10.5, p < 0.01). The relationship between PEF (% of personal best) when the dose was increased (Y) and the days for the increased dose to achieve a PEF greater than PEF in the symptom-free state (X) was determined to be Y = − 0.591X + 89.2 (r2 = 0.299, p < 0.001).
As a guide for increasing the BFC dose when patients with mild asthma have asthma symptoms, the dose should be increased when cough is present or PEF is decreased to 88.9% (i.e., X = 0.5).
The following new article have just been published in Asthma Research and Practice: Associations of physical activity with childhood asthma, a population study based on the WHO - health behaviour in school-aged children survey
Lene Lochte, Poul Erik Petersen, Kim G. Nielsen, Anette Andersen and Thomas A. E. Platts-Mills
Asthma in paediatric populations is one of the highest public health concerns. In this study of children and adolescents, we hypothesized that low levels of physical activity (PA) would show associations with asthma that vary by asthma outcome. The objective was to assess whether PA was associated with ever asthma and/or current asthma.
Analyses were based on 4824 Danish schoolchildren aged 11–15 years old (48.7% boys) participating in the HBSC survey. The study variables were (1) physician-diagnosed asthma (ever asthma) and (2) physician-diagnosed asthma plus wheezing and/or physician or hospital consultation for wheezing (current asthma). Associations with PA by gender were analysed with multivariate logistic regression using the “variance covariance (vce) cluster” method.
The prevalence of ever asthma was 14.3% (boys) and 12.8% (girls), and that of current asthma was 6.8% (boys) and 7.0% (girls). Boys with current asthma showed important differences in low and high PA. We found inverse associations between low PA and ever asthma, odds ratio [95% confidence interval] male: .55 [.30; .99] and female: .47 [.24; .93], and current asthma, male: .27 [.12; .60] (P linear trend = .007) and female: .32 [.11; .94].
The lowest activity levels showed significant inverse associations with asthma, regardless of the definition. For boys, the more stringent (current asthma) of the two paediatric asthma definitions revealed a significant trend with PA, and the direction of associations shifted to positive as weekly PA increased.
New Article From Asthma Research and Practice: Clinical characteristics and comorbidities of elderly asthmatics who attend allergy clinics
To date, few studies have focused on the clinical and allergic characteristics of asthma in the elderly, defined as asthma in people aged 60 or over. Thus, we propose to identify and study the clinical and allergic characteristics and comorbidities of patients with asthma among the elderly.
A retrospective, observational, descriptive study was developed in five clinics and hospitals in Argentina. Allergy Physicians analyzed their patients’ medical records in 2014 and included those adults over the age of 60, who had been diagnosed with asthma according to the GINA guidelines. Clinical and allergic characteristics were analyzed.
A total of 152 patients diagnosed with asthma, of whom 73% were women and 11% ex-smokers, were included in this study, with a mean age of 66 years. Only 10.5% of the participants had onset asthma past the age of 60. Regarding asthma severity, 74.3% were diagnosed with moderate persistent asthma, and 7.2% with severe persistent asthma. Eighty-four percent of the patients were treated with an inhaled corticosteroid (ICS) along with a long-acting β 2-adrenergic agent (LABA). More than half of the patients had two or more comorbidities simultaneously. Allergic comorbidities were the most frequent comorbidities, followed by arterial hypertension. Among allergic comorbidities, most patients presented allergies at the nasal level. There were no significant differences between the subpopulations of patients with late-onset asthma (LOA) and asthma with onset before the age of 60, i.e. early onset asthma (EOA) in most of their clinical characteristics. However, it was observed that EOA accounted for a higher percentage of patients with nasal allergies as compared to LOA (71% vs 46%, p < 0.05).It is worth mentioning that almost half of the patients with LOA had allergies at the nasal level.
These results may provide a better understanding of the clinical characteristics of asthma in the elderly in Argentina, thus, enabling the development of future therapeutic strategies and a better quality of life for our elderly asthma patients.
