Although they both display several distinct medical phenotypes and different biomarkers, you will find no ideal biomarkers to stratify asthma phenotypes and guideline therapy in medical practice. Nevertheless, some biomarkers may be helpful to select subsets of atopic individuals which might benefit from biologic providers, such as omalizumab. Individuals with severe asthma, uncontrolled besides ideal treatment, notwithstanding nonatopic, may also benefit from omalizumab therapy, although currently you will find no randomized double-blind placebo controlled clinical trials to support this suggestion. However, omalizumab discontinuation relating to each patient’s response to therapy and pharmacoeconomical analysis are questions that remain to be answered. 1. Intro Asthma is definitely a heterogeneous disease, Maprotiline hydrochloride usually characterized by chronic MYH9 airway swelling. It is defined by the history of respiratory symptoms such as wheeze, shortness of breath, chest tightness, and cough that vary over time and in intensity, together with variable expiratory airflow limitation [1]. The prevalence of asthma, probably one of the most common chronic diseases in the world [2, 3], offers improved during the 1970s and 1980s. Epidemiologic studies from your 90s suggested the prevalence of asthma was around 7.7% in the United States (US)over 22 million peopleand lethality rate was estimated at 5.2 per 100,000 asthmatic individuals per year. Worldwide, 200C300 million people suffer from asthma [1C3], and severe asthma comprises 5-10% of all asthmatic individuals [4]. In Portugal, the prevalence of asthma is definitely estimated to be of 6.8% [5], affecting around 1 million people. Of these, only 57% have controlled disease, which means that around 300,000 Portuguese asthmatics need a better treatment to control their disease. The number of hospitalizations due to asthma was 2,728 in 2016, from a total of 262,229 asthmatic individuals authorized in the Portuguese National Health Services. The standardized mortality rate was, in 2015, of 4.0/100,000 inhabitants for individuals above 65 years of age, and of 0.1/100,000 inhabitants for individuals below 65 years of age. Nevertheless, and according to the latest Organisation for Economic Co-operation and Development (OECD) report, Portugal is probably the countries with less mortality and the country with less hospitalizations due to asthma [6]. The high prevalence Maprotiline hydrochloride of asthma, the impairment of quality of life, the absenteeism, and the large health resources needed to manage this disease makes the economic burden of asthma one of the highest among all chronic diseases. Asthma-related costs have been estimated at up to 2% of the economic cost of all diseases in developed countries [7]. A recent systematic review examined 68 papers within the economic burden of asthma between 1966 and 2008 and concluded that despite the availability of effective preventive therapies, the cost of asthma treatment offers increased significantly over the last few decades [8]. A study carried out in Portugal in 2010 2010 concluded that asthma in adults poses a significant economic burden within the Portuguese healthcare system. Total costs amounted to a grand total of 386,197,211.25, with direct costs representing 93% or 359,093,559.82, 2.04% of the total Portuguese healthcare expense in 2010 2010. The major costs were acute care utilization (30.7%) and treatment (37.4%). A considerable portion of this burden might be eased by improving asthma control in individuals, as uncontrolled individuals’ costs are more than double those of controlled asthma individuals [9]. Severe asthma has a heterogeneous definition. The World Health Organization (WHO) suggests that severe asthma includes three organizations: (1) untreated asthma; (2) incorrectly treated asthma (as a result of nonadherence, persistent causes, or comorbidities); and (3) difficult-to-treat asthma. It is also important to distinguish between severe asthma, comprising patients requiring medium/high doses of inhaled corticosteroids in combination Maprotiline hydrochloride with LABA or additional controller, and uncontrolled asthma, resulting from improper therapy or prolonged problems with adherence or comorbidities [1]. According to the English Recommendations for Asthma, hard asthma is defined as that with prolonged symptoms and/or frequent asthma attacks despite treatment with high-dose therapies or continuous or frequent use of oral steroids [10]. Untreated patients have been recently omitted in the 2014 revision document produced by the task force of.
