Serum Vitamin D Is Inversely Associated with Blood Eosinophil Count Among Adults with Allergic Asthma.

Objective: To evaluate the role that serum vitamin D concentration plays in the number of eosinophils in peripheral blood in adults with allergic asthma.

Material And Methods: A total of 142 patients were categorized based on different cutoff points for eosinophils: ≥200, ≥300, ≥400, and ≥500 cells/mL. The vitamin D concentration was stratified into <20 and ≥20 ng/mL.

[Prevalence of cow´s milk allergy and lactose intolerance among Mexican late adolescents].

Objective: To determine the prevalence of cow´s milk allergy and lactose intolerance in a sample of late adolescents.

Methods: Through a population-based study, data corresponding to students with aged 15 to 18 years were analyzed.

Results: A total of 1992 adolescents was analized.

Beyond eosinophilia: inflammatory patterns in patients with asthma.

Recently, inflammatory cell ratios have gained importance as useful indicators in the categorization of asthma. We compared the concentration of white blood cells in peripheral blood, as well as their respective inflammatory cell ratios, between patients with asthma and a healthy control group. We performed cross-sectional analyses of the data obtained from 53 adult patients with asthma and 109 adult controls.

[Mexican consensus on fractional exhaled nitric oxide (FeNO) in asthma 2020].

The fractional exhaled nitric oxide (FeNO) is related to the level of eosinophilic inflammation in the airways and the levels of interleukin-13, as such it could be a diagnostic and monitoring tool in asthma. A working group was convened between pulmonologists, respiratory physiology experts, and allergists to establish criteria for the use of FeNO in asthma in Mexico. Through a simplified Delphi method and group discussion, seven key points regarding the use of FeNO were agreed upon.

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines.

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice.

Anxiety and depression in adult patients with asthma: the role of asthma control, obesity and allergic sensitization.

Objective: To determine the frequency of anxiety and depression in adult patients with asthma and to identify factors associated with them.

Methods: This cross-sectional study included 164 consecutively recruited patients with asthma aged ≥ 18 years. Participants were clinically assessed and the mental state was analyzed through of the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI-II); the Asthma Control Test (ACT) was measured, and allergic sensitization and respiratory function were also evaluated.

Peanut allergy among Mexican adults with allergic respiratory diseases: prevalence and clinical manifestations.

Background: Peanut allergy among adults with respiratory diseases has seldom been studied within Mexico.

Objective: To establish the prevalence of peanut allergy among adults that have been diagnosed with either asthma or allergic rhinitis; we will also be describing the symptoms that are associated with peanut allergy.

Methods: We carried out a cross-sectional study through which we analyzed the corresponding data of 257 patients with allergic respiratory diseases, asthma or allergic rhinitis, all participants were 16 years of age or older, and were recruited in a consecutive manner.

The characterization of asthma with blood eosinophilia in adults in Latin America.

To identify and characterize asthma with blood eosinophilia in adults. : This cross-sectional study consisted of 164 asthma patients, aged 18 years or older. Multivariate analyses by logistic regression were performed to identify clinical characteristics and biomarkers associated with asthma with blood eosinophilia (defined as asthma and a peripheral blood eosinophil count ≥400 cells/mm).
