For patients diagnosed with sarcoidosis, changes in ACE levels were also observed. Of the 3781 patients (51.1% men, 60.1 \u00b1 17.0 years old), 477 were excluded for taking ACE inhibitors and\/or immunosuppression agents or those with any diseases affecting serum ACE levels. In 3304 patients including 215 with sarcoidosis, serum ACE levels were 19.6 IU\/L [interquartile range, 15.1\u201331.5] in patients with sarcoidosis and 10.7 [8.4\u201316.5] in those without sarcoidosis (P &amp;lt; 0.01), and the best cut-off value was 14.7 IU\/L with 0.865 of the area under the curves. Compared with the current ACE cut-off of 21.4, the sensitivity improved from 42.3 to 78.1 at the new cut-off, although specificity slightly decreased from 98.6 to 81.7. The ACE level significantly decreased more in those with immunosuppression therapy than in those without it (P for interaction &amp;lt;0.01), although it decreased in both groups (P &amp;lt; 0.01).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Because the sensitivity for detecting sarcoidosis is comparatively low at the current standard value, further examinations are needed for patients suspected of sarcoidosis with relatively high ACE levels in the normal range.
