Abstract

Patient registries are valuable tools to study long-term morbidity and mortality of rare diseases. Acromegaly is rare (incidence 3-4/mill/year, prevalence 40-70/mill; approx. 300 new patients/yr and up to 5700 patients in Germany). Diagnostic and therapeutic possibilities have considerably improved, but treatment results remain often unsatisfactory. The main cause is residual disease activity after surgery, most importantly due to invasive macroadenomas. The German Acromegaly Registry is an initiative of the Pituitary Study Group of the German Endocrine Society (DGE). Formally established in January 2003 by the Board of the DGE, long-term financial support is guaranteed by an unrestricted grant from Novartis Pharma GmbH to the DGE. The registry cooperates closely with the United Kingdom and the Austrian registries. The aim of the German Acromegaly Registry is to establish a database of sufficient epidemiological strength in order to (1) document co-morbidity and mortality, (2) provide data on diagnostic and therapeutic procedures/effectiveness, (3) enable comparison of procedures in different national centres, (4) provide information for patient support groups/interaction with health care providers, (5) enable comparison with other national registries within Europe. The registry has at present 82 participating centres, and 42 have included patients (20 university clinics, 8 non-university hospitals, 14 centres in private practice). The database aims to include all acromegalic patients in Germany who are cared for and treated at present. Up to December 2005 1543 patients have been entered in a retrospective manner. Data collection is by external monitoring by highly trained study nurses who visit the individual centres. Inclusion is planned to continue at a rate of 500 per year. Starting in 2005 centres are revisited every 3 years at a rate of 500 per year (prospective phase of the registry). Quality of the data has been validated by an independent monitoring team which demonstrated high data concordance. Conclusions: Initial results of the German Acromegaly Registry show that it was possible to include a large number of patients within 3 years into the registry. Data quality has been validated and shown to be satisfactory. Therefore, the registry will be a useful tool to study long-term morbidity and mortality in a large series of patients.
