Probe-based confocal laser endomicroscopy in diagnosis of diffuse cystic lung disease in Sjögren's syndrome.

Sjögren's syndrome is systemic autoimmune disease characterized by lymphocytic infiltration of various organs with wide frequency of pulmonary involvement. Diffuse cystic lung disease in Sjögren's syndrome is a rare condition and requires differential diagnosis with other cystic pathologies such as lymphangioleyomiomatosis or Langerhans cell histiocytosis. Probe-based confocal laser endomicroscopy (pCLE) is a method of in vivo investigation of airways and lung tissue on microscopic level during bronchoscopy. We used this method in diffuse cystic lung disease caused by Sjögren's syndrome. The pCLE image showed a large number of fluorescent cells presumably lymphocytes in bronchioles, dilated alveolar spaces with fluid and thin alveolar walls. We think that the presence of the bronchiolar cells pattern can be used to differentiate between the pulmonary manifestations of Sjögren's disease and other cystic lung diseases.

Thermovaccination - thermoheliox as a stimulator of the immune response. Kinetics of the synthesis of antibodies and C-reactive protein in coronavirus infection.

Clinical trials of thermoheliox application (inhalation with a high-temperature mixture of oxygen and helium, 90 °C) in the treatment of the acute phase of coronavirus infection were conducted. Dynamics of disease development in infected patients (PCR test for the virus) and, dynamics of changes in blood concentration of C-reactive protein, immunoglobulin M, specific immunoglobulin G were studied. High efficiency of thermoheliox in releasing the organism from the virus and stimulating the immune response (thermovaccination effect) was shown. The kinetic model of the process is proposed and analyzed.
