SUN-300 Improvement in Cardiovascular Risk Factors in Long Term Follow up of Hypopituitary Septagenarian and Octagenarian Patients

Background: Hypopituitarism in the elderly population is an underdiagnosed condition and may increase co-morbidities in glucose metabolism, dyslipidemia and cardiovascular risk factors. Pituitary macroadenomas are benign tumors, which prevalence is unknown in aged people, and is frequently associated to impairment in pituitary function. Objective: The aim of this study is to identify cardiovascular risk factors in hypopituitary septagenarians and octagenarians by diagnosis and after long term follow up of pituitary dysfunction. Methods: This is a retrospective observational study and the patients were recruited and selected from a service registry in a tertiary medical center. We included patients aged from 70-99 years with the diagnosis of pituitary macroadenomas, evaluated hormonal and biochemical parameters, cardiovascular risk scores were calculated by diagnosis and compared after long term follow up. All patients signed informed consent. Results: Thirty five patients were included, 21 patients aged 70-75 years (72.61 yo), 7 patients 76-80 years (77.28yo), 7 patients 81-99 years (89.28 yo). All tumors were macroadenomas, 40% of them Non Functioning Pituitary Macroadenomas, mean maximal diameter 3.4 cm (2.9-.4.3), 40% of them submitted to surgery, 14% adjuvant radiotherapy, 20% presented previous apoplexy. Co-morbidities were frequent by diagnosis, 85.71% presented Hypertension, 37.14% Diabetes, 62.8% Hypercholesterolemia and 45.71% Hypertriglyceridemia. Hypopituitarism was present in 71.42%, GH deficiency in 37.14%, hypogonadism in 60%, central hypothyroidism in 54.28%, adrenal insufficiency in 31.42%, 51.42 % presented more than two combined deficiencies. Analysis of cardiovascular risk prediction in total cohort showed, 57.14% of patients presented reduction of Framingham Score and 45.71% in Coronary Calcium Score, during mean time follow up of 13.09 years (3-32 years after diagnosis). According to ages, Framingham score and Coronary Calcium Score reduced respectively in 66% and 33.3% (70-75 yo), 57.15% and 85.71% (76-80 yo) and 42.85% and 28.57% (81-99 yo), during long term follow up. Discussion and Conclusion: In this study, most of hypopituitary aged patients presented reduction of cardiovascular risk factors during long term treatment and follow up, despite replacement with corticosteroids and gonadal steroids. Considering the importance of early diagnosis and the lack of data observed in the medical literature, larger scale studies should be performed with the objective to assess of the risk benefit ratio of hormonal replacement in metabolic control in septagenarian and octogenarian patients.
