Also, 110 healthy volunteers were also recruited as healthy controls (HC, 37.0 ± 8.4years, 70 female). -, Tan EM, et al. Zeng designed research; C.J. 21, 289–294 (1978). 62, 2569–2581 (2010). It is worth to note that in our study, the positive rates of anti-SmD1 in naive, non-naive and unselected total SLE patients were 68.00%, 56.80% and 60.97% respectively, which indicate that the positive rate of anti-SmD1 in patients with SLE was fluctuated with the different patients recruited. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Ishii, M. et al. No. Arthritis Res Ther. Anti-Sm antibody was first detected in sera of SLE patients in 19667. High positivity for anti-SmD1 only among patients with SLE (14.0% in naive SLE and 16.0% in non-naive SLE) indicated the importance and necessity of detectinganti-SmD1 in patients with SLE, especially in anti-dsDNA negative SLE patients. It is reactive with human, mouse and rat. 33, 57–63 (2014). By submitting a comment you agree to abide by our Terms and Community Guidelines. Lancet. The mean SLEDAI did not differ significantly between naive (9.02 ± 8.01) and non-naive (10.60 ± 8.45) SLE patients, but the incidences of arthritis, renal disorder, neurologic disorder, and abnormal antinuclear antibody in non-naive SLE patients were higher than those in naive SLE patients. All samples with an optical density higher than the cut-off were considered as positive (The cut off value of anti-SmD1, anti-Sm and anti-dsDNA antibodies is 25 U/ml, 20 RU/ml and 100 IU/ml respectively), and the concentration of each antibody type was calculated according to the respective standard curve. -, Yaniv G, et al. In another study, the first IgG autoantibodies to appear were directed against U1-RNP-70 and SmB/B′, followed by anti–U1-RNP-A, anti–RNP-C, and anti-SmD1 antibodies. In the past decade, patients’ quality of life and survival continue to be improved along with progress in timely, appropriate diagnosis and earlier treatment of SLE3, for which the detection of autoantibodies plays an important role. doi: 10.7759/cureus.4783. Article Concentrations of anti-SmD1, anti-Sm and anti-dsDNA in eight naive SLE patients before and after treatment. Int J Rheum Dis (2016). Jaekel HP, Klopsch T, Benkenstein B, Grobe N, Baldauf A, Schoessler W, Werle E. J Autoimmun. After conducting the logarithm transformation of anti-SmD1, anti-Sm and anti-dsDNA concentrations, paired t-tests were used to analyze the anti-SmD1, anti-Sm, and anti-dsDNA levels in the serum of patients before and after treatment. 2019 Oct;47(10):5070-5081. doi: 10.1177/0300060519871812. Winfield, J. Reactivities to the Sm autoantigenic complex and the synthetic SmD1-aa83-119 peptide in systemic lupus erythematosus and other autoimmune diseases. -, Arbuckle MR, et al. Concentrations of anti-SmD1, anti-Sm and anti-dsDNA in eight naive SLE patients before and after treatment. 8600 Rockville Pike The results of cross-positivity for anti-SmD1, anti-Sm, and anti-dsDNA are shown in Fig. 16, 67–69 (2007). Hu, C., Li, M., Liu, J. et al. Quantification of serum anti-SmD1, anti-Sm, and anti-dsDNA antibody concentrations in SLE patitents, rheumatic disease control and healthy control are shown in Fig. Prevention and treatment information (HHS). 5. The anti-SmD1[sub]83-119 antibody has exhibited higher sensitivity and specificity than anti-Sm antibody in diagnosing adult SLE. Anti-SmD1 antibodies are associated with renal disorder, seizures, and pulmonary arterial hypertension in Chinese patients with active SLE - NASA/ADS. Ahn, S. S. et al. CAS 2, 235–240 (2003). 25, 1271–1277 (1982). We found that the concentration of anti-SmD1 autoantibodies was significantly higher in the SLE group (1630.6 ± 6686.9 U/ml) than in the RDC group (15.3 ± 43.3 U/ml; P = 0.000) or the HC group (25.1 ± 105.7 U/ml; P = 0.000). 1 A proline-rich SmD1 cross-reacting octapeptide PPPGMRPP of the carboxyl terminal regions of SmB/B′ was among the first targets of the anti-Sm responses.

Bethesda, MD 20894, Copyright PubMed Screening of SLE sera using purified recombinant Sm-D1 protein from a baculovirus expression system. The concentration of anti-SmD1 in the same naive SLE patient before and after treatment was analyzed using the paired t-test. We observed that compared to the single assay of anti-dsDNA, the combination of anti-Sm and anti-dsDNA did not improve the diagnostic sensitivity, specificity and accuracy for SLE, while the combination of anti-SmD1 and anti-dsDNA antibodies outperformed in terms of the sensitivity of anti-SmD1 or anti-dsDNA antibodies alone. Autoimmun Rev. Contents of Kit. Anti-SmD1 C-terminus ELISA kit measures anti-SmD1 antibodies in the serum. The positive rate of anti-SmD1 among all SLE patients was 60.97%, higher than that in the RDC group (13.30%, P = 0.000) or the HC group (9.09%, P = 0.000). 2005 Mar 26;149(13):688-93. Aletaha, D. et al. Of the 169 non-naive SLE patients, the positivity for anti-SmD1 only (16.0%) was higher than that for anti-Sm only (1.2%, χ The gene SMD1 may have Genomic and Proteomic products available from Sigma-Aldrich.
