Interferons alpha and gamma, pidotimod, and tilorone in the treatment of acute respiratory infections in patients with allergic rhinitis: a prospective, cohort clinical and immunological study
Aim. To compare the clinical efficacy and influence on interferon (IFN) production / sensing of drugs with immunemediated antiviral effects, which potentiate type 1 (T1) immune responses, in the treatment of acute respiratory infections (ARI) in patients with allergic rhinitis.Materials and methods....

| description | Aim. To compare the clinical efficacy and influence on interferon (IFN) production / sensing of drugs with immunemediated antiviral effects, which potentiate type 1 (T1) immune responses, in the treatment of acute respiratory infections (ARI) in patients with allergic rhinitis.Materials and methods. 146 ARI patients with remission of seasonal allergic rhinitis were divided into 4 cohorts. In addition to symptomatic therapy, patients received either 2,000 IU of IFNγ in each nasal passage 5 times a day; or rectal suppositories containing 106 IU of IFN-α2b and antioxidants (AO) twice a day, and a gel with IFN-α2b and AO intranasally 3 times a day; or 400 mg of pidotimod per os twice a day; or 125 mg of tilorone per os on days 1, 2, 4, and 6. The severity of ARI was determined daily as the sum of 10-point scores for 15 symptoms. Serum concentrations of IFNα and IFNγ and the ability of blood cells to produce these cytokines ex vivo spontaneously and upon stimulation with Newcastle disease virus or phytohemagglutinin were studied using enzyme-linked immunosorbent assay (ELISA). The proportions of circulating lymphocytes expressing type I IFN receptor subunit 2 (CD118) or IFNγ receptor α-chain (CD119) were determined by flow cytometry.Results. ARI symptoms in all cohorts generally regressed in a similar way. However, from day 5 of the treatment, pidotimod relieved symptoms more effectively than other drugs. In patients treated with tilorone, the regression of ARI manifestations was delayed in the first two to three days, followed by rapid symptom reduction. An initial decrease in the induced production of IFNγ was found in patients treated with pidotimod, and a tendency to a decrease in this parameter was noted in other cohorts. The induced production of IFNγ after the treatment in all groups did not differ from that in healthy donors. No significant changes and differences in the proportions of CD118+ and CD119+ lymphocytes were found between the cohorts, except for a decrease in the number of CD118+ cells after the treatment with tilorone. In patients treated with IFN-α2b + AO, the proportions of CD119+ and CD118+ lymphocytes tended to increase slightly.Conclusion. Drugs that promote the development of T1 over T2 immune responses are a useful option for treating ARI in patients with allergic rhinitis. |
