The Level of Angiotensin-Converting Enzyme as Indicator of 2-Year Prognosis in Untreated Pulmonary Sarcoidosis without Erythema Nodosum
2009
. In order to evaluate the prognostic significance of elevated serum angiotensin-converting enzyme (SACE) in pulmonary sarcoidosis, the 2-year prognosis was studied in 33 untreated patients without erythema nodosum. Elevated SACE was found in 19 patients among whom total regression or improvement was noted in 42%, against 86% in 14 patients with normal SACE in serial measurements. The groups with and without elevated enzyme levels were not different with respect to sex, age, pulmonary changes, or extrathoracic manifestations. Thus, the finding of elevated SACE in this category of sarcoidosis patients may have some prognostic significance, pointing toward a greater risk of a chronic course.
