Milos, Gabriella; Moergeli, Hanspeter; Sob, Cynthia; Wisler, Doris; Wasila, Mariusz; Uebelhart, Daniel; Frey, Diana (2021). Positive Effect of Teriparatide on Areal Bone Mineral Density in Young Women with Anorexia Nervosa: A Pilot Study. Calcified tissue international:Epub ahead of print.

Abstract

The present pilot study investigated the effect of Teriparatide 1-34 rh-PTH (TPT) in young women diagnosed with anorexia nervosa (AN), and markedly compromised Bone Mineral Density (BMD). Patients were included who had (i) very low BMD (defined as Z-Score <  - 2.5 or T-Score <  - 2.5 if available) in at least one of the assessed localizations (lumbar spine L1-L4, total hip, femoral neck) without any previous fragility fracture; or (ii) low bone mineral density (defined as Z-Score <  - 1.5 or T-Score <  - 1.5 if available) in at least one of the assessed localizations (lumbar spine L1-L4, total hip, femoral neck) and at least one previous fragility fracture. Ten patients with an age range of 21-33 were recruited and their bone outcome was assessed after 12, 18, and 24 months. After 24 months of TPT treatment, BMD improved by 13.5% in the spine, 5.0% in the femoral neck, and 4.0% in the hip. Radius cortical bone density (- 2.6%) and radius cortical thickness (- 6.4%) decreased significantly, while in tibia there was no significant decrease. Neither in radius nor in tibia a significant change in trabecular bone parameters occurred. During the treatment, the patients' body weight did not increase significantly. Patients did not experience severe adverse events; only mild side effects were observed. Although these results emerged from a single-arm prospective study, it seems that AN patients with a severely compromised bone situation can benefit from TPT. Larger studies are needed to ascertain the effect of this promising substance.
