Polimorfizmi gena za receptor beta2-adrenergičkih (ADRB2) su klinički
relevantni iz nekoliko razloga, uključujući i kao faktor rizika za nastanak astme,
stepen njene težine, kao i modulacije efikasnosti terapije beta2-agonista. Cilj
ovog istraživanja bio je da se ispita povezanost između ADRB2 polimorfizama
gena i astme u srpskoj populaciji, te da se proceni terapijski odgovor u odnosu
na ADRB2 genotip.
U istraživanju je učestvovalo 171 bolesnika s astmom i 101 zdravih osoba kao
kontrolna grupa.
Genotipizacija Arg16Gly i Gln27Glu polimorfizama je izvedena direktnim
sekvenciranjem prozvoda lančane reakcije polimeraze (PCR).
U srpskoj odrasloj populaciji, nosioci 27Gln alela i 27Gln / Gln genotipa su
pokazali veći rizik od nastanka astme [(OR) 2.5, 95% interval poverenja (CI) 1,6-
3,8, a OR 3.00, 95% CI 1,7-5,3, odnosno], dok je nađeno da prisustvo 27Glu alela
i 27Gln / Glu genotip imaju zaštitni efekat (OR 0.4; 95% CI 0,3-0,6, ili OR, 0.3,
95% CI 0.1-0.7, respektivno). Nadalje, utvrdili... smo da prisustvo 27Gln alela u
astmatičara mlađih od 50 godina dovodi do boljeg odgovora na terapiju s dugodelujućim
beta2-agonistima (LABA) u kombinaciji sa niskim i umerenim
dozama inhalacijskih kortikosteroida (ICS), za razliku od starijih gde nosioci
27Glu alela stariji od 50 godina imaju veću verovatnoću da će bolje odgovoriti
na LABA + ICS terapiju.
U zaključku, identifikovali smo da su u srpskoj odrasloj populaciji 27Gln alel i
homozigotna kombinacija 27Gln faktori rizika za nastanak astme, što može biti
od kliničkog interesa u prevenciji bolesti...
Polymorphisms of beta2-adrenergic receptor gene (ADRB2) are clinically
relevant for several reasons, including as a risk factor for asthma
development/severity and prediction for the effectiveness of treatment with
beta2-agonists in reducing asthma symptoms. The aim of this study was to
examine the association between ADRB2 gene polymorphisms and asthma in
Serbian population, and to evaluate the therapeutic response in relation to the
ADRB2 genotype.
The study included 171 patients with asthma and 101 healthy subjects as the
control group.
Genotyping of Arg16Gly and Gln27Glu polymorphisms was performed by
direct sequencing of polymerase chain reaction (PCR) products.
In Serbian adults, carriers of the 27Gln allele and 27Gln/Gln genotype were at
higher risk of asthma [odds ratio (OR) 2.5, 95% confidence interval (CI) 1.6-3.8,
and OR 3.00, 95% CI 1.7-5.3, respectively], while the presence of the 27Glu allele
and 27Gln/Glu genotype were found to be protective of asthma (OR 0.4, 95%
CI 0.3...-0.6, and OR 0.3, 95% CI 0.1-0.7, respectively). Furthermore, we found that
the presence of the 27Gln allele in asthmatics younger than 50 years leads to a
better response to therapy with long-acting beta2-agonists (LABA) in
combination with prevailing low and moderate doses of inhaled corticosteroids
(ICS), while carriers of the 27Glu allele over 50 years old are more likely to
respond to LABA + ICS therapy.
We identified that in Serbian adults the 27Gln allele and 27Gln homozygosity
are risk factors for asthma, which may be of clinical interest in disease
prevention...
