Introduction. Acromegaly is a chronic disease associated with high mortality rate if untreated. The aim of the study is to evaluate mortality ratio in Romanian patients with acromegaly in latest years, with new therapeutic options. Patients and Methods. This retrospective study analyzed 336 (111M/225F, mean age 48.13±12.40 years) consecutive patients with acromegaly between 1st January 2001 and 31 December 2014, median follow-up 7.36 years (0.48-13.99 years). PAMCOMP computation program assessed standardized mortality ratio (SMR). Kaplan Meier curve was used for comparison between of different cut-off levels of the last GH level on survival. Serum GH levels were measured by IRMA (sensitivity 0.1 ng/mL). Results. During follow-up 2596.34 person-years, 41 patients died, with a SMR of 1.34 (CI 0.96-1.82). Mean age at death was 63.19±11.66 years. Females with acromegaly died 83% more frequently than women in general population: SMR-1.83 (CI 1.21-2.67). Females were older at diagnosis (p=0.006), and were less probable to receive substitution of gonadotrophic failure than males (p<0.001). Independent factors correlated with mortality were age at baseline (p<0.001, HR=1.07), last GH level (p=0.003, HR=1.01) and systolic blood pressure (p=0.029, HR=1.02). Patients with last GH level ≤ 1 ng/mL had a better survival than patients with GH>1 ng/mL (p Log Rank=0.002). SMR of patients with last GH >1 ng/mL was 1.59 (CI 1.08-2.26) for the entire group, 2.2 (CI 1.32-3.44) for females and 1.3 (CI 0.67-2.29) for males. Conclusion. Patients with acromegaly have a high mortality ratio compared to general population, especially in women and those with post-therapeutic serum GH levels over 1 ng/mL. Longer follow-up is needed for the evaluation of the effect of new therapies on mortality.
