BackgroundThere are limited FDA-approved medications and real-world data on sarcoidosis treatment in the U.S. and concordance of practice patterns with guideline recommendations have not been well characterized.Research QuestionWhat are the practice patterns and factors associated with treatment for patients with sarcoidosis in the year following diagnosis?Study Design And MethodsWe conducted a retrospective analysis of patients with sarcoidosis from 2016 - 2022 using a multicenter, all-payer, claims database (TriNetX). We ascertained treatments with corticosteroids and/or non-steroidal immunosuppressive medications (methotrexate, mycophenolate, leflunomide, hydroxychloroquine, cyclophosphamide, infliximab, adalimumab, azathioprine, rituximab, and janus kinase inhibitors) within one year of diagnosis. We summarized treatment rates, sequence of prescribed medications by mean rank, and used multivariable logistic regression analyses to identify factors associated with treatment.ResultsOut of 13,330 patients with sarcoidosis meeting inclusion, 5,671 (42.5%) received treatment within a year of diagnosis. Of those treated, 60% received steroids alone, 13% received non-steroidal immunosuppressives alone, and 27% received both. Further, 25% of treated patients received a non-steroidal immunosuppressive as their first medication. Corticosteroids had the lowest mean rank order, indicating they were, on average, the first medication initiated. Among those with pulmonary or cutaneous involvement, the second medication initiated on average was hydroxychloroquine, while in those with cardiac or neurologic involvement it was adalimumab and mycophenolate, respectively. Factors associated with higher odds of treatment were Black race, organ involvement at baseline (pulmonary, cardiac, and neurologic), and comorbid diagnoses (fatigue, hypercalcemia, and ILD).InterpretationWithin the first year of diagnosis, 43% of patients with sarcoidosis were started on treatment. Non-steroidal immunosuppressives were used in 40% of treated patients. While factors associated with treatment initiation aligned with guideline recommendations, practice patterns of treatment were variable, particularly in choice and sequence of non-steroidal immunosuppressive therapy, underscoring the need for future trials and comparative effectiveness studies.Copyright © 2024 American College of Chest Physicians.
