Moreover, patients with CT, TT, or CT+TT genotype increased the risk of AR incidence in the in the -17C/T site of HRH1, and CC genotype and CT+TT genotype were associated with gender, asthma, VAS score, total IgE level, and specific IgE level in patients with AR.
Histamine H1 receptor (H1R) gene is upregulated in patients with allergic rhinitis (AR), and its expression level is strongly correlated with the severity of allergic symptoms.
It has been reported that the histamine H1 receptor (H1R) gene is up-regulated in patients with allergic rhinitis and H1R expression level strongly correlates with the severity of allergy symptoms.
It has been reported that the histamine H1 receptor (H1R) gene is up-regulated in patients with allergic rhinitis and H1R expression level strongly correlates with the severity of allergy symptoms.
These results may have an important clinical implication for understanding the role of histamine H1 receptor on upper airway diseases such as allergic rhinitis and nonallergic rhinitis.
However, in the treatment of diseases as chronic pruritus, asthma and allergic rhinitis the use of histamine H(1) receptor antagonists is unsatisfying.
