    Abstract:
    PURPOSE: Accumulative studies showed that tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) was up-regulated in the blood and urine from patients diagnosed with lupus nephritis (LN) and that it might be used as a novel biomarker for active LN. This meta-analysis aimed to determine the diagnostic value of TWEAK in active LN. METHODS: We searched the Cochrane Library, Embase, PubMed, Springer, Wanfang and CNKI databases for articles published up to 20 August 2020. The diagnostic capacity of TWEAK for active LN was assessed using pooled sensitivity and specificity, positive and negative likelihood ratios (PLR and NLR), diagnostic odds ratio (DOR), and area under the receiver operating characteristic curve (AUC). Quality assessment and publication bias were also evaluated. STATA 11.0 and Meta-Disc 1.4 were used to perform these analyses. RESULTS: Nine cross-sectional studies were included in this meta-analysis. The overall pooled sensitivity of TWEAK for the diagnosis of active LN was 0.69 (95% CI, 0.63-0.75), and specificity was 0.77 (95% CI, 0.71-0.82). The overall pooled PLR and NLR were 3.31 (95% CI, 2.05-5.35) and 0.38 (95% CI, 0.26-0.55), respectively, with a DOR of 10.89 (95% CI, 6.73-17.63) and AUC (SE) of 0.8276 (0.0289). Deeks' funnel plot revealed that the publication bias was insignificant in the study (p = .32). CONCLUSIONS: Our results suggest that TWEAK might be a potential biomarker for patients with active LN. Future cross-sectional and longitudinal studies are needed to confirm its diagnostic value, as well as to establish more definite cutoff for active LN.
