Gender Differences and SNPs in Asthmatic Patients

• Status: Unknown
• Phase: —
• Study type: Observational
• Enrollment: 50 (estimated)
• Sponsor: University of Catanzaro · Academic / Other
• Sex: All
• Age: 6 Years – 75 Years
• Healthy volunteers: Accepted

Summary

The GINA 2020 guidelines suggest that asthma affects approximately 300 million persons worldwide. Even if there is a specific drug treatment for each stage of disease (From mild to severe) in some patients it is not efficacy and it culd be reated to the gender difference Polymorphisms seems to be involved in asthma (allergic or not) even if no data have been published concerning the role of gender in this clinical manifestation. The aim of this study is to assess whether genetic variations involved in the genes encoding the two key leukotriene enzymes, ALOX5 and LTC4S, and CysLTR1 are implicated in the sex difference of allergic asthma in a well-characterized patient cohort.

Detailed description

The GINA 2020 guidelines suggest that asthma affects approximately 300 million persons worldwide. Even if there is a specific drug treatment for each stage of disease (From mild to severe) in some patients it is not efficacy and it culd be reated to the gender difference Polymorphisms seems to be involved in asthma (allergic or not) even if no data have been published concerning the role of gender in this clinical manifestation. The role of polymorphisms in susceptibility to allergic asthma has been partially investigated but no study has analysed gender subgroups separately, neglecting a their potential predictive role in symptomatological and functional variations in the allergic asthma in both sexes. The aim of this study is to assess whether genetic variations involved in the genes encoding the two key leukotriene enzymes, ALOX5 and LTC4S, and CysLTR1 are implicated in the sex difference of allergic asthma in a well-characterized patient cohort.

Conditions

• Allergic Asthma
• Asthma

Interventions

Type	Name	Description
GENETIC	genetic evaluation	A sampe of blood (3 mL) and of oral mucosa will be take and analyzed using nCounter GX Human Inflammation Kit a comprehensive number of 8SNPs in 3 human genes known to be differentially expressed in allergic asthma.
OTHER	MicroRNA evaluation	Using the sampe of blood (3 mL) using RT-PCR we will evaluate the expression of microRNA in enrolled patients
