Early prediction of sarcoidosis prognosis with HLA typing: a 5 year follow-up study.

A wide range of HLA-DR alleles have been associated with sarcoidosis either in terms of disease phenotype or extra pulmonary involvement, however the effect on non-resolution in different ethnic groups is not fully understood. The aim of this study was to investigate whether disease characterics and HLA-DRB1 alleles may early reflect non resolution in sarcoidosis. 91 patients who were diagnosed in Cukurova University Faculty of Medicine Department of Chest Diseases between 1993-2012 and were followed up until June 2017 were included in the study.
