Purpose:
The evaluation of acromegalic osteopathy is a subject of current interest as there is a lack of evidence concerning proper evaluation techniques and clear diagnostic criteria. The aim of this study was to evaluate lumbar spine trabecular bone score (TBS) and bone mineral density (BMD) in acromegaly patients compared to healthy controls.
Methods:
We conducted a cross-sectional study on 43 acromegaly patients recruited between 2018 and 2020 and a healthy control group matched 1:1 for age, gender, and body mass index (BMI). All subjects underwent DXA, lumbar spine TBS, and bone turnover markers measurement.
Results:
Acromegaly patients showed significantly decreased lumbar spine TBS (1.244 ± 0.117 vs. 1.343 ± 0.124, p < 0.001) and no difference regarding BMD compared to control patients. In the subgroup analysis, TBS was significantly lower in both males and females (1.282 ± 0.075 vs. 1.366 ± 0.113, p = 0.01 and 1.222 ± 0.132 vs. 1.329 ± 0.130, p = 0.005) and, also, in hypogonadal and eugonadal acromegaly subjects compared to their healthy controls (1.231 ± 0.130 vs. 1.306 ± 0.125, p = 0.04 and 1.280 ± 0.065 vs. 1.381 ± 0.113, p = 0.008). Femoral neck BMD was higher in acromegalic hypogonadal patients [1.027 (IQR: 0.939-1.135) vs. 0.876 (IQR: 0.737-1.014), p = 0.004].
Conclusion:
Our study indicates that TBS, but not BMD, is significantly decreased in acromegaly patients, regardless of gender and gonadal status. This data suggests that TBS could be a valuable tool in the assessment of acromegalic osteopathy.
