- PURPOSE:Early diagnosis is a success factor for the prevention of long-term comorbidity and premature death in patients with acromegaly, but large-scale data on the diagnostic process and disease management are scarce. Therefore, we aimed to evaluate the diagnostic process, implementation of treatment and changes in life situation in patients with acromegaly, focusing on sex-specific differences.METHODS:Non-interventional patient-reported outcome study. 165 patients with clinically and biochemically proven acromegaly were questioned about the diagnostic process and utilization of health care by means of a self-developed standardized postal survey including questions on acromegaly symptoms experienced before diagnosis, number and specialty of consulted doctors, time to diagnosis and aftercare.RESULTS:The diagnostic process took 2.9 (SD 4.53) years, during which 3.4 (SD 2.99) physicians were consulted. Women waited longer [4.1 (SD 5.53) years] than men [1.6 (SD 2.69) years; p = 0.001] for the correct diagnosis, and consulted more doctors in the process [4.0 (SD 2.99) vs. 2.7 (SD 2.84) doctors, p < 0.001, respectively]. In 48.5 % of patients, acromegaly was diagnosed by an endocrinologist (men: 45.1 %; women: 52.4 %). Overall disease duration from symptom onset until last surgery was 5.5 (SD 6.85) years, with no sex differences. A change in employment status was the most commonly reported event after diagnosis and a quarter of the patients stated that the illness had changed their lives.CONCLUSIONS:Our findings confirm the urgent need to increase awareness of the clinical manifestation of acromegaly to facilitate an earlier diagnosis of the disease and to provide diagnostic equality across the sexes.

- Purpose: Despite availability of multimodal treatment options for acromegaly, achievement of long-term disease control is suboptimal in a significant number of patients. Furthermore, disease control as defined by biochemical normalization may not always show concordance with disease-related symptoms or patient’s perceived quality of life. We developed and validated a tool to measure disease activity in acromegaly to support decision-making in clinical practice. Methods: An international expert panel (n = 10) convened to define the most critical indicators of disease activity. Patient scenarios were constructed based on these chosen parameters. Subsequently, a panel of 21 renowned endocrinologists at pituitary centers (Europe and Canada) categorized each scenario as stable, mild, or significant disease activity in an online validation study. Results: From expert opinion, five parameters emerged as the best overall indicators to evaluate disease activity: insulin-like growth factor I (IGF-I) level, tumor status, presence of comorbidities (cardiovascular disease, diabetes, sleep apnea), symptoms, and health-related quality of life. In the validation study, IGF-I and tumor status became the predominant parameters selected for classification of patients with moderate or severe disease activity. If IGF-I level was ≤1.2x upper limit of normal and tumor size not significantly increased, the remaining three parameters contributed to the decision in a compensatory manner. Conclusion: The validation study underlined IGF-I and tumor status for routine clinical decision-making, whereas patient-oriented outcome measures received less medical attention. An Acromegaly Disease Activity Tool (ACRODAT) is in development that might assist clinicians towards a more holistic approach to patient management in acromegaly.
