| Abstract | OBJECTIVES: To better understand the effect of TNF- inhibitors (TNFi) on new bone formation in ankylosing spondylitis (AS) patients. METHODS: We systematically searched the articles in EMBASE and PubMed. RESULTS: Fifteen articles were enrolled. In all the 9 TNFi-treated cohorts, the vertebral corners with inflammatory lesions at baseline were at higher risk to develop new syndesmophytes than those without inflammatory lesions, although a few syndesmophytes also developed at the vertebral corners without inflammatory lesions at baseline. The advanced inflammatory lesions including fat deposition on baseline MRI showed a higher risk for syndesmophyte formation than the acute inflammatory lesions. Because the number of analyzed vertebral corners were too small, it might not be true that new syndesmophytes developed more frequently at the corners with inflammatory lesions completely resolved than those with persistent inflammation after TNFi treatment. Four studies with 2-year follow-up revealed null effect of TNFi on radiographic progression compared with historical controls with lower disease activity, and 3 studies with ≥4-year follow-up proved inhibitory effect of TNFi on new bone formation in AS patients. Patients with a delay of >10 years in starting TNFi therapy were more likely to experience radiographic progression as compared to those who started earlier. CONCLUSIONS: In TNFi treated AS patients, baseline inflammation is linked with syndesmophyte development. An earlier initiation of TNFi therapy may slow the radiographic progression in AS, and TNFi may lose its benefit of retarding new bone formation at advanced stage of AS especially after the focal fat infiltration or syndesmophyte formation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
