A registry of acromegaly patients and one year following up in Taiwan.

Background/purpose: The objectives of this study were to describe epidemiological data, treatment outcomes, and quality of life (QOL) of patients with acromegaly in Taiwan.

Methods: From 2013 to 2015, subjects with acromegaly were recruited through five medical centers. After enrollment, each patient was kept on observation for 1 year.

Results: The analyzed cohort included 272 acromegalic subjects (117 males, 155 females) with a mean age of 51.4 ± 12.9 years. Their mean age at diagnosis was 41.8 ± 12.1 years. About 83.8% patients presented symptoms of facial changes. Galactorrhea was noted at the earliest age of 32.7 ± 9.1 years. The duration between the onset of symptoms/signs and diagnosis was 6.9 ± 8.1 years. Around 70.3% patients harbored a macroadenoma. At enrollment, percentages of patients ever received surgical intervention, radiotherapy, somatostatin analogs, and dopamine agonists were 94.8%, 27.9%, 64%, and 30%, respectively. At the final following-up visit, the random growth hormone (GH), nadir GH after oral glucose tolerance test, and the insulin-like growth factor 1 levels were 2.7 ± 4.9 μg/L, 2.4 ± 6.1 μg/L, and 291.5 ± 162.4 ng/mL, respectively. The remission rate assessed by random GH level (≦2 μg/L) was 63.8%. The mean AcroQoL scores for the total 22 items were 64.0 ± 19.7. About 42.8% patients never sensed or felt discomfort about their changes in appearance.

Conclusion: This study described the profiles of acromegaly in Taiwan. It is important to enhance early diagnosis and timely commencement of treatment to prevent serious complications of acromegaly.
