Study will evaluate safety and efficacy of the investigational medical product (IMP) - interferon-gamma - in participants with HIV-infection and pulmonary tuberculosis.~Interferon-gamma (immune interferon) is an important anti-inflammatory cytokine produced by NK-cells, CD4 Th1 cells and CD8 cytotoxic supressor cells. Interferon-gamma blocks viral replication, viral proteins synthesis and assembly of mature viral particles. Causes cytotoxic effects on the cells infected by intracellular pathogens. Possess a bright immunomoduling action. Thus, the use of interferon-gamma is patogenetically rational in patients co-infected with tuberculosis and HIV.~The aim of interferon-gamma use is to achieve a viral replication control, support CD4 level and help abacillation process. In this randomised, controlled safety and efficacy study interferon gamma will be administered in a daily dose of 500,000 IU daily or every other day.~The treatment regimen in this study will also include a basic antituberculosis therapy.~The available clinical data do not suggest a risk for serious adverse events (SAEs) from the IMP used in chosen doses.~The study will screen HIV-infected participants 18-50 years old with pulmonary tuberculosis. Participants who provide informed consent and meet study entry criteria will be randomised into 1 of 3 parallel treatment groups. The study will last 30 days, during which participants will receive IMP in various regimens according to the group.
The primary purpose of this study is to assess the safety and efficacy of interferon-gamma by subcutaneous injection in complex treatment of patients with co-infection of HIV and pulmonary tuberculosis and to determine the rational of its use.
