Clinical characteristics and treatment outcomes in acromegaly, a retrospective single-center case series from Thailand.

Introduction: acromegaly, an overproduction of growth hormone (GH), is associated with high rate of morbidity and mortality particularly in case of delayed in diagnosis and treatment. A wide variation of clinical presentations, treatment outcomes and morbidities have been reported. Methods: a retrospective study was conducted to review clinical characteristics and treatment outcomes of patients with acromegaly treated in King Chulalongkorn Memorial Hospital, Bangkok, Thailand, between 2006 and 2018. Results: eighty-four patients (31 males and 53 females) were reviewed, mean age at diagnosis was 45.7 ± 12.6 years (±SD), mean time of disease onset was 7.6 ± 6.4 years and mean follow-up period was 7.8 ± 5.3 years. The most common presenting symptoms were maxillofacial change (96.8%) and acral enlargement (94.7%). Hypertension (39.3%), diabetes mellitus (28.6%) and dyslipidemia (23.8%) were prevalent co-existing conditions. Four patients were identified having cancer at presentation; however, no additional malignancy was reported during the follow up. Most patients harbored macroadenomas, only 10 were found to have microadenomas. The outcomes of treatment were controlled disease in 70% of microadenoma and 64.9% of macroadenoma. Permanent loss of pituitary function was found in about 21.3% and there was one case reported of mortality. The logistic regression analysis for controlled disease outcome showed the IGF-I index after surgery was associated with controlled disease outcome with statistically significant result (P-value= 0.006).==Replace this with the results section of the abstract== Conclusion: our study offers descriptive clinical data of case series of acromegalic patients, which had favorable outcomes comparable with previous reports. In addition, IGF-I index after surgery is a predictive parameter for outcome of treatment. [ABSTRACT FROM AUTHOR]
