Risk of depression in patients with acromegaly in Korea (2006-2016): a nationwide population-based study

초록

BACKGROUND: An increased prevalence of depression has been reported in patients with acromegaly. However, most studies included a relatively small sample size owing to the rarity of acromegaly. We aimed to investigate the risk of depression in patients with acromegaly using the Korean National Health Information Database (NHID). METHODS: The data of patients with acromegaly in 2006-2016 were collected from the rare incurable disease registry of the NHID. Patients with acromegaly were matched with control participants without acromegaly for age and sex in a 1:5 ratio. RESULTS: Patients who did not receive treatment for acromegaly had a significantly increased risk of depression (hazard ratio [HR]: 1.43, 95% confidence interval [CI]: 1.12-1.82). However, the risk of depression did not increase in patients who received treatment for acromegaly. The multiple Cox regression analysis showed that the risk of depression was significantly higher in the untreated group than in the control group during the first 3 years of observation (HR: 1.829, 95% CI: 1.305-2.563). However, after a time lag of over 3 years, the risk of depression decreased in the untreated group, which is similar to that in the control group. CONCLUSION: Our nationwide study suggests that patients who did not receive treatment for acromegaly have a higher risk of depression compared with controls. The untreated acromegaly patients should be monitored for the development of depression, especially in the early years after diagnosis. These results could serve as a basis for developing screening strategies to mitigate depression in acromegaly patients.
