Diagnosis and Management of Asthma in Adults: A Review.

JAMA. 2017 Jul 18;318(3):279-290

Authors: McCracken JL, Veeranki SP, Ameredes BT, Calhoun WJ

Importance: Asthma affects about 7.5% of the adult population. Evidence-based diagnosis, monitoring, and treatment can improve functioning and quality of life in adult patients with asthma.
Observations: Asthma is a heterogeneous clinical syndrome primarily affecting the lower respiratory tract, characterized by episodic or persistent symptoms of wheezing, dyspnea, and cough. The diagnosis of asthma requires these symptoms and demonstration of reversible airway obstruction using spirometry. Identifying clinically important allergen sensitivities is useful. Inhaled short-acting β2-agonists provide rapid relief of acute symptoms, but maintenance with daily inhaled corticosteroids is the standard of care for persistent asthma. Combination therapy, including inhaled corticosteroids and long-acting β2-agonists, is effective in patients for whom inhaled corticosteroids alone are insufficient. The use of inhaled long-acting β2-agonists alone is not appropriate. Other controller approaches include long-acting muscarinic antagonists (eg, tiotropium), and biological agents directed against proteins involved in the pathogenesis of asthma (eg, omalizumab, mepolizumab, reslizumab).
Conclusions and Relevance: Asthma is characterized by variable airway obstruction, airway hyperresponsiveness, and airway inflammation. Management of persistent asthma requires avoidance of aggravating environmental factors, use of short-acting β2-agonists for rapid relief of symptoms, and daily use of inhaled corticosteroids. Other controller medications, such as long-acting bronchodilators and biologics, may be required in moderate and severe asthma. Patients with severe asthma generally benefit from consultation with an asthma specialist for consideration of additional treatment, including injectable biologic agents.

Acupuncture for asthma: Protocol for a systematic review.

Medicine (Baltimore). 2017 Jun;96(26):e7296

Authors: Li M, Zhang X, Bao H, Li C, Zhang P

BACKGROUND: Asthma is a common chronic disease in both adults and children. Inhaled corticosteroids (ICS) and β2-agonists are the major medications treating asthma with many side effects. Acupuncture has been used in many diseases including asthma. We aim to assess the efficacy and safety of acupuncture for asthma.
METHODS: The following electronical databases will be searched from inception to January 1, 2017: Medline, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), SinoMed, the China National Knowledge Infrastructure Database (CNKI), the Chinese Scientific Journal Database (VIP database), and the Wanfang database. We will also search reference lists of identified studies, potential gray literatures, relevant conference abstracts, and registers of clinical trials. Two reviewers will independently undertake study selection, data extraction, and quality assessment. Data will be synthesized by either the fixed-effects or random-effects model according to a heterogeneity test. Changes in lung function will be assessed as the primary outcome. The level of control, medication usage, quality of life, exacerbations, symptoms, adverse events will be evaluated as the secondary outcomes. The RevMan V.5.3.5 will be employed for meta-analysis. Continuous outcomes will be presented as mean difference or standard mean difference, while dichotomous data will be expressed as relative risk.
RESULTS: This study will provide a high-quality synthesis of current evidence of acupuncture for asthma from several aspects including lung function, the level of control, medication usage, quality of life, exacerbations, symptoms and adverse events.
CONCLUSION: The conclusion of our study will provide updated evidence to judge whether acupuncture is an effective intervention for children with asthma.
ETHICS AND DISSEMINATION: It is not necessary for ethical approval because individuals cannot be identified. The protocol will be disseminated in a peer-reviewed journal or presented at a relevant conference.

Modeling long-term effects attributed to nitrogen dioxide (NO2) and sulfur dioxide (SO2) exposure on asthma morbidity in a nationwide cohort in Israel.

J Toxicol Environ Health A. 2017;80(6):326-337

Authors: Greenberg N, Carel RS, Derazne E, Tiktinsky A, Tzur D, Portnov BA

Studies have provided extensive documentation that acutely elevated environmental exposures contribute to chronic health problems. However, only attention has been paid to the effects of modificate of exposure assessment methods in environmental health investigations, leading to uncertainty and gaps in our understanding of exposure- and dose-response relationships. The goal of the present study was to evaluate whether average or peak concentration exerts a greater influence on asthma outcome, and which of the exposure models may better explain various physiological responses generated by nitrogen dioxide (NO2) or sulfur dioxide (SO2) air pollutants. The effects of annual NO2 and SO2 exposures on asthma prevalence were determined in 137,040 17-year-old males in Israel, who underwent standard health examinations before induction to military service during 1999-2008. Three alternative models of cumulative exposure were used: arithmetic mean level (AM), average peak concentration (APC), and total number of air pollution exposure episodes (NEP). Air pollution data for NO2 and SO2 levels were linked to the residence of each subject and asthma prevalence was predicted using bivariate logistic regression. There was significant increased risk for asthma occurrence attributed to NO2 exposure in all models with the highest correlations demonstrated using the APC model. Data suggested that exposure-response is better correlated with NO2 peak concentration than with average exposure concentration in subjects with asthma. For SO2, there was a weaker but still significant exposure response association in all models. These differences may be related to differences in physiological responses including effects on different regions of the airways following exposure to these pollutants. NO2, which is poorly soluble in water, penetrates deep into the bronchial tree, producing asthmatic manifestations such as inflammation and increased mucus production as a result of high gaseous concentrations in the lung parenchyma. In contrast, SO2, which is highly water soluble, exerts its effects rapidly in the upper airways, leading to similar limited correlations at all levels of exposure with fewer asthmatic manifestations observed. These data indicate that differing exposure assessment methods may be needed to capture specific disease consequences associated with these air pollutants.
