About

Treatment of patients with allergic rhinitis and chronic polypous rhinosinusitis with olfactory mucosa-derived mesenchymal stem cells

Full description

During the implementation of the project, the methods for the treatment of allergic rhinitis and chronic polypous rhinosinusitis with olfactory mucosa-derived mesenchymal stem cells will be developed.

The positive outlook for the effectiveness of MSCs is due to the following:

• knowledge of the leading role of immunopathogenetic mechanisms in the development of allergic rhinitis and chronic polypous rhinosinusitis and the pronounced immunomodulating properties of MSCs;
• the ability of MSCs to reduce the production of proinflammatory cytokines and suppress immune inflammation;
• positive results of preclinical studies of the method of treatment of diseases accompanied by over-activation of the immune system, including autoimmune diseases, in animals and the first clinical studies in patients.

Enrollment: 60 estimated patients

Exclusion criteria

• The presence of any malignant tumor within the last 5 years
• Acute or chronic diseases in the stage of decompensation
• Chronic infectious diseases: HIV, viral hepatitis B, C, tuberculosis
• Patients who are pregnant, breastfeeding, or fertile patients who are not using adequate contraceptive methods
• Chronic and protracted mental disorders, all diseases with the presence of the syndrome of dependence on alcohol, drugs and psychoactive substances, any other condition that makes the patient unable to understand the nature, extent and possible consequences of the study or, in the opinion of the researcher, prevents the patient from observing and performing protocol
• Patients are unable or unwilling to give written informed consent and / or follow research procedures
• Any other medical condition that, in the opinion of the investigator, may be associated with an increased risk to the patient or may affect the outcome or evaluation of the study
