Is every joint symptom related to acromegaly?

Acromegaly is a chronic endocrinopathy characterized by the hypersecretion of growth hormone and insulin-like growth factor-1. Musculoskeletal pain is a frequent problem encountered in acromegaly and is associated with a reduction in the quality of life. In this study, the presence of inflammatory and degenerative rheumatologic diseases in acromegaly has been retrospectively evaluated. Forty patients with acromegaly who were in remission according to laboratory findings, but still having joint and back pain problems, were referred to rheumatology outpatient clinic and all the patients were examined by clinical, radiological, and laboratory data. Mean age was 47.1 years (22-75). When the radiological data were evaluated, erosions of the left sacroiliac joint were found by means of magnetic resonance imaging in 1 patient and degenerative joint changes were observed in 24 patients by X-ray imaging. However, there was no pathology in the radiological data of 15 patients. Laboratory data revealed antinuclear antibody positivity (3 nucleolar and 1 homogeneous) in 4 patients, rheumatoid factor positivity in 4, and cyclic citrullinated peptide positivity only in 1 patient. The diagnosis of an inflammatory rheumatologic disease, including rheumatoid arthritis, ankylosing spondylitis, or undifferentiated connective tissue disease was made in 3 patients. Besides, the diagnosis of diffuse idiopathic skeletal hyperostosis was also established in 6 patients. While degenerative joint diseases were frequently observed in our group similar to the literature, inflammatory rheumatologic diseases were also found in three patients. Distinguishing these two diseases is important because response to medical treatment is dramatically better in inflammatory diseases than in degenerative pathologies. A multidisciplinary approach is imperative for appropriate management of these patients.
