Besides the study by Swigris et al1 and our cohort, one other study found a twofold-higher rate of PE in sarcoidosis patients in a 35-year record linkage study.2 The cause for the association between sarcoidosis and PE remains speculative. There might be a role for medication (eg, corticosteroid use) or coexistence of an antiphospholipid syndrome.3 Immunosuppressive therapy may have played a role in our cohort, because this was a selected population with severe sarcoidosis and previous or current use of steroids was higher than in the general sarcoidosis population. However, two patients had PE before they started immunosuppressive therapy. We have insufficient information about antiphospholipid syndrome in our cohort. Among the 11 patients who had PE, there was only one current smoker and three former smokers (<10 pack-years). Smoking is not a well-established risk factor for PE and, therefore, not a likely explanation for the high rate of PE in this cohort.
