Survey the effect of drug treatment on modulation of cytokines gene expression in allergic rhinitis.

Allergic rhinitis as common airway disease has high prevalence in all peoples worldwide. In allergic diseases, Th2 cells release type 2 cytokines that support the inflammation in airways. All the drugs used for allergic rhinitis do not cure completely, and the choice of drugs according to cost and efficacy is very important in all groups of atopic patients. Therefore, in this study, the effect of commercial drugs on cytokine gene expression has been studied. Male Balb/c mice were divided into six groups. Allergic rhinitis was induced in five of the six groups with ovalbumin, and four of these five groups were treated with salbutamol, budesonide, theophylline, and montelukast. The fifth group was used as positive control group and the sixth group as negative control group. For the survey, RNA was extracted, cDNA was synthesized, and quantitative real‐time PCR was done for 21 genes. The four drugs had different effects on mRNA expression of cytokines (IL‐1b, 2, 4, 5, 7, 8, 9, 11, 12, 13, 17, 18, 22, 25, 31, 33, 37, IFN‐γ, TNF‐α, TGF‐β1, and eotaxin) in the allergic rhinitis groups. Salbutamol can be used during pregnancy and breastfeeding, but it has some side effects. Budesonide in the inhaled form is generally safe in pregnancy. Theophylline cannot control allergic attack in the long run. Montelukast is not useful in the treatment of acute allergic attacks. Immunomodulatory and anti‐inflammatory effects of drugs in control of allergic rhinitis via Th2 cytokines can be new approaches in molecular medicine. [ABSTRACT FROM AUTHOR]
