Sarcoidosis: federal clinical guidelines for diagnosis and treatment

Sarcoidosis is a multi-organ granulomatosis  of unknown  origin. Modern  diagnostic methods  allow detecting  this disease at an early stage. The absence of specific markers requires a comprehensive  approach  to diagnosis based on comparison  of radiation,  clinical, morphological  and functional data. The course of sarcoidosis without damage to the respiratory system presents significant difficulties. It is extremely important  to understand the time and means of starting Sarcoidosis’s treatment to avoid the early initiation  of hormones  and cytostatics and, on the other hand,  to timely respond to progression and threatening  conditions.  Methods. Clinical recommendations are based on the analysis of Russian and English publications of the latest sarcoidosis research. The target audience of these clinical guidelines are therapists, general practitioners, pulmonologists, TB doctors, rheumatologists,  dermatologists,  radiation diagnosticians,  immunologists,  and clinical pharmacologists.  Each thesis-recommendation for diagnosis and treatment is evaluated on an 1 to 5 scale of levels of evidence and an A, B, C scale of the grades of recommendations. The clinical guidelines also contain comments and explanations for the theses-recommendations, diagnostic algorithms, treatment strategies, reference materials on the use of recommended drugs. Conclusion. Current information  on epidemiology, clinical manifestations,  diagnosis and management  strategies for patients with sarcoidosis are covered in the presented clinical guidelines.
