OBJECTIVE: Endogenous Cushing syndrome is associated with an intrinsic hypercoagulable state and an increased risk of venous thromboembolism (VTE). This study aimed to determine the prevalence and risk factors for VTE in a large cohort of patients with Cushing disease (CD).
METHODS: A retrospective study was conducted at a tertiary care center, including 408 patients diagnosed with CD. Clinical, laboratory, hormonal, imaging, and outcome data were analyzed and compared based on the occurrence of VTE events. A control group of 323 patients with clinically nonfunctioning pituitary adenomas, all macroadenomas, who underwent similar surgical procedures, was used for comparison.
RESULTS: VTE events were observed in 35 patients with CD (8.6%) and in 1 patient from the nonfunctioning pituitary adenoma group (0.3%; P < .001). The slight majority of VTE events (54%) occurred in the preoperative period. Logistic regression analysis identified obesity, mood disorders, supraclavicular fossa fullness, leukopenia or leukocytosis, elevated cortisol levels (both serum and 24-hour urinary cortisol), and the presence of postoperative complications (such as infections, cerebrospinal fluid leak, and vasopressin deficiency) as significant risk factors for VTE.
CONCLUSION: The findings of this study confirm a high prevalence of VTE events in patients with CD, irrespective of the surgical period. Risk factors associated with a higher likelihood of VTE include obesity, severity of hypercortisolism, and the occurrence of postoperative complications. In this patient population, thromboprophylaxis should be considered.
