Abstract
Effective transsphenoidal surgery (TSS) for Cushing`s disease (CD) normalizes cortisol levels and reduces complications of hypercortisolism. However, there is evidence of increased cardiovascular morbidity even after successful surgery. A prospective, controlled study on the dynamics of fibrinogen and D-dimer levels with a six-month follow-up after an effective TSS for CD. Forty patients with CD and forty healthy age- and sex-matched subjects were included. We assessed ACTH, urinary and serum cortisol, and fibrinogen and D-dimer levels before TSS and during follow-up. Baseline BMI (P < 0.001), fibrinogen (P = 0.002), and D-dimer (P = 0.001) levels in CD patients were significantly higher than those in healthy controls. High fibrinogen levels in the CD group were independent of BMI, and were positively associated with hsCRP (rS = 0.61, P < 0.001) and arterial hypertension (P = 0.029). After the six-month follow-up we confirmed a sustained difference between the remission group and controls in fibrinogen and D-dimer levels (P = 0.001 and P = 0.017, respectively). Despite early biochemical remission of CD the levels of fibrinogen and D-dimer failed to decrease. This probably contributes to the high risk of thrombotic events and indicates the need for a close follow-up for signs of thromboembolic and cardiovascular complications in patients with early CD remission.
