To date, solely hips, knees, hands, and spinal joints have been radiographically assessed. Therefore, this study aimed to assess the prevalence of joint symptoms and radiographic osteoarthritis (OA) of new, and established peripheral joint sites in well-controlled acromegaly. Methods: Fifty-one acromegaly patients (56% female, mean age 64 +/- 12 years) in long-term remission for 18.3 years (median, IQR 7.2-25.4) were included. Nineteen patients currently received pharmacological treatment. Self-reported joint complaints were assessed using standardized interviews. Self-reported disability of the upper and lower limbs, and health-related quality of life (HR-QoL) were evaluated using validated questionnaires. Radiographic OA [defined as Kellgren & Lawrence (KL) >= 2] was scored using (modified) KL methods. Results: Radiographic signs of OA were present in 46 patients (90.2%) with >= 2 joints affected in virtually all of these patients (N = 44; 95.7%). Radiographic MTP1 OA was as prevalent as radiographic knee OA (N = 26, 51.0%), and radiographic glenohumeral OA was similarly prevalent as hip OA [N = 21 (41.2%) vs. N = 24 (47.1%)]. Risk factors for radiographic glenohumeral OA were higher pre-treatment IGF-1 levels [OR 1.06 (1.01-1.12), P = 0.021], and current pharmacological treatment [OR 5.01 (1.03-24.54), P = 0.047], whereas no risk factors for MTP1 joint OA could be identified. Conclusion: Similar to previously-assessed peripheral joints, clinical and radiographic arthropathy of the shoulder and feet were prevalent in controlled acromegaly. Further studies on adequate management strategies of acromegalic arthropathy are needed. Show less

Show moreThis thesis describes the long-term consequences of growth hormone and insulin-like growth factor I excess in patients cured from acromegaly for a mean duration of 17 years. Regarding the considerable prevalence of diverse morbidity in these patients, during the active phase of the disease but even more so after 17 years of disease cure, we suggest the screening of acromegalic patients on highly frequent comorbidities, such as osteoarthritis, vertebral fractures, colonic polyps, and colonic diverticulae. It is of great concern to recognize the long-term consequences of the disease in order to offer the patients adequate follow-up and multidisciplinary care. The aim should be to control the persisting complex morbidity as much as possible in order to prevent the patients from a further decrease in quality of life. The patients__ physician as well as the patient itself should be aware of the long-term consequences of acromegaly in order to eliminate surreal expectations concerning recovery of certain comorbidities.
