Heiting et al. investigated whether the initiation of IL-17 blockade with secukinumab improves bone turnover, bone mineral density, and microarchitecture in axSpA patients. Despite symptomatic benefits of therapy with secukinumab, with improvements in pain and function, there were few biochemical, densitometric, or microarchitectural changes in skeletal health over two years of treatment with secukinumab. Larger, longer-term controlled studies using sensitive metrics such as HR-pQCT to follow bone quality are needed to improve our understanding of bone health in axSpA and the relation to disease activity and therapy.
