Risk for acromegaly-related comorbidities by sex in Korean acromegaly.

Reports on the incidence, characteristics, and comorbidity in Asian patients with acromegaly are scarce.To evaluate the incidence of acromegaly and risk of comorbidities in East Asia, especially South Korea.This nationwide population-based cohort study using the Korean Health Insurance Review and Assessment Claims Database evaluated the incidence of acromegaly, initially diagnosed from 2010 to 2013. We identified comorbidities during, before, and 2 years after diagnosis. Acromegaly and control cases (718 and 7,180, respectively) were included in the analysis.A longitudinal case-control study using a nationwide population cohort.The mean annual incidence rate of acromegaly was 3.57 cases per million. Malignancies occurred in 61 patients with acromegaly (8.5%) during the study period and thyroid cancer was the most common malignancy (n=38). In the acromegaly group, the overall risk of malignancy was higher: hazard ratio (HR), 2.82 (95% confidence interval [CI]: 2.12-3.74). Malignancy risk was more pronounced in females, with increased risk from the pre-diagnosis period that sustained until the post-diagnosis period. Prevalence of diabetes mellitus (DM) and heart failure increased significantly in acromegalic patients. Over the entire period, DM developed in 51.1% and 57.0% of male and female acromegalic patients, respectively. Mortality risk was higher (HR 1.65, 95% CI: 1.13-2.41) and statistically significant in females (HR 1.75, 95% CI: 1.07-2.84).
