Angiotensin-Converting Enzyme: Investigation of Diurnal Variation, the Effect of a Large Dose of Prednisolone, and Prednisolone Pharmacokinetics in Patients with Sarcoidosis 1– 2
Abstract
Serial assay of serum angiotensin-converting enzyme concentrations (SACE) is advocated for monitoring disease progress in sarcoidosis. Because little is known of nondisease factors affecting SACE, 10 patients with histologically proved sarcoidosis were assessed for diurnal fluctuation in SACE and as to whether a large dose of corticosteroid had an immediate effect on SACE independent of disease. The pharmacokinetics of prednisolone in 8 of these patients was also evaluated. On Day 1, serum samples were obtained for 24 h after placebo, and the next day at the same times after 75 mg of orally administered prednisolone. There was no obvious diurnal pattern on either day, and there was no significant difference in SACE after prednisolone. The mean maximal difference obtained within or between days was 8.8%. Prednisolone pharmacokinetics were comparable to normal volunteers. SACE concentrations can be confidently determined at any time of day, and changes of greater than 9% are probably significant. The use of prednisolone in patients with sarcoidosis can be safely based upon pharmacokinetic data obtained from normal volunteers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
