Dynamics of endogenous interferon-alpha and -gamma production under the influence of ingaron therapy in patients with chronic epstein – barr viral infection with chronic fatigue syndrome

The influence of antiviral therapy with ingaron on the dynamics of production of interferons α and γ and clinical effects in patients with chronic viral Epstein – Barr infection was studied. The study involved 51 patients (33 women and 17 men aged 35,27 ± 1,28 years) suffering from chronic infection caused by the Epstein – Barr virus. The duration of the disease from the appearance of the first complaints to laboratory confirmation of the Epstein – Barr virus infection and diagnosis was 2,23 ± 0,21 years. Determined the serum, spontaneous and induced production of cytokines interferons α and γ in serum and in the culture of lymphocytes. Three months after the end of antiviral therapy, in patients with an initially low level of induced interferon-γ, the production of interferon-γ increased. The absence of an increase in the production of induced interferon-γ in patients one and three months after the end of therapy with ingaron indicates the absence of the effect of the drug on the level of endogenous interferon-γ. It has been established that the initially low level of induced interferon-γ can be a marker of the positive effect of the therapy with ingaron. Correlation analysis revealed the effect of baseline interferon-γ induced on the clinical picture of the disease. Thus, initially a high level of induced interferon-γ (2706 ± 1058.94 pg/ml) inversely affects the development of sweating in patients (r = –0.506, p = 0,023; τ = –0.419, р = 0.021), and initially low level of the induced IFN-γ (287.2 ± 64.65 pg/ml) — on development of weakness (r = –0.405, р = 0.045; τ = –0.419, р = 0.037). In general, ingarone can be used in the therapy of patients with chronic Epstein virus — Bar infection at a dose of 500,000 IU every other day, at least 10 injections.
