| Abstract | Objective To assess the efficacy and safety of clinical trials of biologics in improving the salivary gland (SG) function in primary Sjögren’s syndrome (pSS), which has not been analyzed critically and systematically. Methods Pubmed, Web of Science, ClinicalTrials.gov, EU Clinical Trials Register and Cochrane Library were searched for clinical trials that reported effects of biological treatment on the SG function and safety in pSS patients. Inclusion criteria were defined following PICOS (participants, interventions, comparisons, outcome and study design) recommendations. The objective index (the change of unstimulated whole saliva flow, UWS), and the serious adverse event (SAE) were assessed as main outcome measures. A meta-analysis of the efficacy and safety of the treatment was conducted. Quality assessment, sensitivity analysis and publication bias were assessed. The effect size together with 95% confidence interval was used to estimate the efficacy and safety of biological treatment, and was plotted as a forest plot. Results The literature search yielded 6678 studies, 9 of which fulfilled the inclusion criteria, with 7 randomized controlled trials (RCT), and 2 non-RCT clinical studies. Generally, biologics did not significantly increase the UWS from baseline of pSS patients than the control group at matched time point (p = 0.55, standardized mean difference, SMD = 0.05, 95% confidence interval, CI: -0.11, 0.21). However, pSS patients with shorter disease duration (≤3 years, SMD = 0.46, 95% CI: 0.06, 0.85) were prone to have a better response to biological treatment by showing higher increased UWS than patients with longer disease duration (> 3 years, SMD = -0.03, 95% CI: -0.21, 0.15) (p=0.03). For the meta-analysis of the safety of biological treatment, the SAEs in the biologics group were significantly higher than the control group (p=0.0021, log odds-ratio, OR = 1.03, 95% CI: 0.37, 1.69). Conclusion Biological intervention during the early course of the disease may benefit pSS patients better than during the late course. Significantly more SAEs in the biologics group indicate that the safety of biologics needs to be addressed for future biological clinical trials and treatment. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
