Objectives: The French Acromegaly Registry records data of acromegalic patients' since 1992 in French, Belgian (Liège), and Swiss (Lausanne) centers. We studied the prevalence of diabetes in this population looking for risk factors. Patients from one of the centers (Reims) were then analyzed more thoroughly., Methods: This study has been conducted on all the patients recorded from 1999 until 2004 (519 patients). Evolution of cohorts' was reassessed in 2009. Of the different variables recorded in the registry: age, sex, body mass index (BMI), duration of acromegaly, GH, IGF1 and prolactin levels, pituitary tumor size, hormonal deficiencies, presence, duration and treatment of diabetes, hypertension, and rheumatological disease were analyzed., Results: The prevalence of diabetes in the registry was 22.3%. Diabetic patients were older and had a higher BMI. Compared with the data of the French Social Security, acromegalic patients showed a more precocious apparition of diabetes and prevalence was higher in each age group. Compared with non-diabetic acromegalic subjects, diabetic patients had a more prolonged evolution of acromegaly before diagnosis. The levels of GH and IGF1 were not significantly different between the two groups. Only hypertension was significantly more frequent in diabetic patients., Conclusions: In our population, the prevalence of diabetes was estimated to be 22.3%. The GH and IGF1 levels did not appear as predictive factors for the presence of diabetes. On the contrary, age, BMI, and hypertension were significant risk factors as in the general population of type 2 diabetics.

Unlabelled: Multicentric registers such as The French Acromegaly Register provide data on rare disorders that are otherwise difficult to obtain, so avoiding extrapolation from limited data sets. This study focuses on clinical, hormonal and therapy characteristics of acromegaly in people over 70 years old. The objective was to compare this population with the youngest to disclose if the medical management was similar., Patients and Methods: The data were obtained from the 30 centres that have registered patients in the Acromegaly Register since 1999., Results: The register listed 644 acromegaly patients on 1st January 2005, of whom 68 (22 men and 46 women) were over 70 years old, independently of the diagnosis date of their disease. Their average age was 76.8 + or - 5 years (range: 70-95) and they had suffered from acromegaly for 11 + or - 6 years (compared to 7 years in those aged less than 70). Their BMI were similar. Diabetes and hypertension were more frequent than in younger acromegalic patients and in the general French population matched for age. Circulating GH and IGF-1 concentrations were lower than in the younger acromegalic patients on inclusion and 1 year after treatment. There was no significant difference in the tumor size. Only 44% of the patients over 70 underwent surgery, against 90% of patients under 70 years. However, the fractions of young and elderly patients with a controlled disease 1 year after inclusion were the same (51%)., Conclusion: In the limits of the use of register, these data reveal a high prevalence of diabetes and hypertension in the eldest acromegalic patients. Despite much less frequent surgical intervention, patients' disease under control is equivalent to the younger population 1 year after the initial interview, confirming the effectiveness of the choices of treatment.
