METHOD FOR PREDICTING THE PROGRESSIVE COURSE OF RESPIRATORY SARCOIDOSIS Russian patent published in 2023 - IPC A61B5/91 A61B6/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to pulmonology, and can be used to predict the progressive course of respiratory sarcoidosis. In patients with sarcoidosis of the respiratory organs, the FEV₁/VC ratio (as a percentage of the predicted value), the peak expiratory volume flow rate (PEV, as a percentage of the predicted value) are determined using computed tomography densitovometry, the inspiratory index of both lungs is determined (II₂, in percent). Prediction is carried out by comparing the value of the discriminant function (D), calculated using the equation: D = -0.370rFEV₁/VC (% due) - 0.263´ PEV (% due) + 42.642´ II₂, where D is a discriminant function with a boundary value equal to -53.54. When D is less than the boundary value of the discriminant function, a progressive course of respiratory sarcoidosis is predicted.

EFFECT: method provides prediction of the progressive course of respiratory sarcoidosis due to the stated diagnostic criteria.
