Abstract Background: Childhood-onset systemic lupus erythematosus (cSLE) is a kind of chronic inflammatory disease characterized by a highly abnormal immune system. This study aimed to detect expression of the Th cytokines IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-17A, IL-17F, IL-21, IL-22, IFN-γ and TNF-α in the peripheral blood of children with cSLE; clinical symptoms; and a disease index and discuss the relationship between the Th cell cytokine regulatory network and onset of systemic lupus erythematosus (SLE) in children and disease outcome.Methods: A total of 33 children with cSLE and 30 healthy children were enrolled in this study. Children in the cSLE group were classified into the inactive cSLE group or active cSLE group according to their SLE disease activity index 2000 (SLEDAI-2K). Th cytokine profiles in peripheral blood of different groups were detected and analyzed.Results: The levels of IL-2, IL-10 and IL-21 in the cSLE group were significantly higher than those in the healthy control group (P < 0.05, P<0.01 and P<0.01, respectively). The expression of IL-2, IL-10 and IL-21 in the active cSLE group was significantly higher than that in the healthy control group (P<0.05, P<0.01 and P<0.05, respectively), but IL-22 expression was remarkably lower in the active cSLE group than in the healthy control group (P<0.001). IL-21 in the inactive SLE group was significantly higher than that in the healthy control group (P<0.05). The levels of IL-2 and IL-10 in the active cSLE group were significantly higher than those in the inactive cSLE group (P<0.01 and P<0.05). In-depth analysis showed that the expression levels of IL-2 (r=0.382, P=0.028), IL-6 (r=0.514, P=0.002) and IL-10 (r=0.429, P=0.016) were positively correlated with disease activity. Conclusion: This study provides a theoretical basis for the discovery of effective methods to regulate imbalance in T lymphocyte subsets in cSLE, which may open up potential new approaches for the diagnosis of cSLE.

Abstract Background Childhood-onset systemic lupus erythematosus (cSLE) is a kind of chronic inflammatory disease characterized by a highly abnormal immune system. This study aimed to detect the serum levels of Th (T helper) cytokines (IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-17A, IL-17F, IL-21, IL-22, IFN-γ and TNF-α) in cSLE and healthy controls, and then to elucidate their association with clinical manifestations, disease activity and laboratory parameters. In order to provide clues for early diagnosis and timely intervention treatment of cSLE patients. Methods A total of 33 children with cSLE and 30 healthy children were enrolled in this study. Children in the cSLE group were classified into the inactive or active cSLE group according to their SLE disease activity index 2000 (SLEDAI-2 K) score. Th cytokine profiles in the peripheral blood were detected and analysed. Results Levels of IL-2, IL-10 and IL-21 in the cSLE group were significantly higher than those in the healthy control group (P < 0.05, P < 0.01 and P < 0.01, respectively). Expression of IL-2, IL-10 and IL-21 in the active cSLE group was significantly higher than that in the healthy control group (P < 0.05, P < 0.01 and P < 0.05, respectively), but that of IL-22 expression was markedly lower in the active cSLE group than in the healthy control group (P < 0.001). IL-21 in the inactive SLE group was significantly higher than that in the healthy control group (P < 0.05), and levels of IL-2 and IL-10 in the active cSLE group were significantly higher than those in the inactive cSLE group (P < 0.01 and P < 0.05). In-depth analysis showed that after excluding age, gender and drug interference, the levels of IL-2 (P < 0.05), IL-6 (P < 0.05) and IL-10 (P < 0.05) were still positively correlated with SLEDAI-2 K scores. However, the levels of IL-6 (P < 0.05) and IFN- γ (P < 0.05) were still negatively correlated with CD4+/CD8+, and the concentration of IL-6 (P < 0.05) was still positively correlated with the occurrence of nephritis. Conclusion This study provides a theoretical basis for the discovery of effective methods to regulate imbalance in T lymphocyte subsets in cSLE, which may lead to new approaches for the diagnosis of cSLE.

Human Tγσ lymphocytes constitute from 1 to 15% of all peripheral blood lymphocytes. Recent work has demonstrated that this population plays a major role in the pathogenesis of infectious and immune diseases. Increased numbers of γσ T cells have been found in affected skin from systemic sclerosis and chronic cutaneous lupus erythematosus patients.In our study, we have determined the numbers of Tγσ lymphocytes and their subpopulations in peripheral blood from 29 patients with systemic lupus erythematosus (SLE) and in 19 healthy volunteers using flow cytometry and specific monoclonal antibodies. The same cells in uninvolved skin from SLE patients and human controls using immunohistochemical analysis were estimated. T-Cell receptor (TCR) delta chain gene rearrangement was identified with primers for Vσ1, Vσ2 and Vσ3 by the polymerase chain reaction. Statistical analysis showed a significantly decreased number of γσ T cells in SLE patients (26.4 Ī 16.9/μl) compared with the control group (55.3 Ī 20.6/μl) (p<0.001). The number of Vσ2 TCR+ and Vγ9 TCR+ subpopulations was also lower in SLE patients than in healthy persons. No statistical correlation between disease activity and the number of γσ T cells was demonstrated. The percentage of T γσ lymphocytes in clinically normal skin from SLE patients was twice (22.0 Ī 9.4%) that found in the skin from healthy persons (11.1 Ī 5.5%) (p<0.002). Higher percentages of the Vσ2 TCR+ and Vγ9 TCR+ subpopulation of lymphocytes were found in the skin from SLE patients. We have also found positive correlation between the percentage of Tγσ lymphocytes in skin and the activity of SLE (r=0.594, p<0.001), and between subpopulation Vσ3 TCR+ and disease activity (r=0.659, p<0.001). In conclusion, the results of our studies demonstrate that, in patients with SLE, accumulation of Tγσ lymphocytes can be seen in clinically normal skin, and the percentage of these cells correlates with the activity of the disease.

Aim: Autoantibody development plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). In this study, we aimed to determine the diagnostic value of anticarbamylated protein antibody (anti-CarP) antibody in SLE and RA patients and its relationship with disease prognosis. Material & method: Fifty-seven SLE patients (F/M 50/7; median age 40.9 ± 13.7; median disease duration 2 years) who met the 2012 SLICC SLE diagnostic criteria were included in the study. A total of 46 RA patients selected according to the 2010 ACR/EULAR diagnostic criteria (F/M 38/8; median age 54.2 ± 12.4; median disease duration 2 years) were included. A total of 30 healthy individuals were selected as the control group. The anti-CarP antibody was studied by using human anticarbamylated protein antibody ELISA Kit (SunRedBio, Shanghai, China). Results: Anti-CarP antibody positivity was found to be 17.4% in RA patients (p < 0.001), 54.4% in SLE patients (p < 0.001) and 3.3% in the healthy control group. The anti-CarP antibody was determined to predict SLE patients with 54.4% sensitivity and 96.7% specificity compared with the healthy control group (area under the curve: 0.755; p < 0.001). Conclusion: Anti-CarP antibody positivity was significantly higher in the SLE patients compared with the healthy control and RA group. It has significant sensitivity and specificity in both SLE and RA patients compared with the healthy controls.

We have explored the relationship between possible hemostatic changes and clinical manifestation of the systemic lupus erythematosus (SLE) as a function of greater or lesser disease activity according to Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) criteria. Endothelial injury and hypercoagulability were investigated in patients with SLE by measuring thrombomodulin (TM), D-dimer (DDi) and thrombin generation (TG) potential. A total of 90 participants were distributed into three groups: 1) women with SLE presenting with low disease activity (laSLE) (SLEDAI-2K ≤ 4), 2) women with SLE presenting with moderate to high disease activity (mhaSLE) (SLEDAI-2K > 4), and 3) a control group comprising healthy women. Levels of TM and DDi were higher both in the laSLE and mhaSLE groups compared to controls and in mhaSLE compared to the laSLE group. With respect to TG assay, lagtime and endogen thrombin potential, low concentrations of tissue factor provided the best results for discrimination among groups. Analysis of these data allow us to conclude that TM, DDi and TG are potentially useful markers for discriminating patients with very active from those with lower active disease. Higher SLE activity may cause endothelial injury, resulting in higher TG and consequently a hypercoagulability state underlying the picture of thrombosis common in this inflammatory disease.

Abstract Background Systemic lupus erythematosus (SLE) is an independent risk factor for cardiovascular events. The present study determined the prevalence of subclinical atherosclerosis in childhood-onset SLE using the carotid intima-media thickness (CIMT) measurement and investigated associations between traditional and nontraditional risk factors for atherosclerosis, such as medications, SLE Disease Activity Index - SLEDAI-2 K and SLICC-ACR damage index and CIMT. Methods Cross-sectional prospective study between 2017 and 2018. CIMT was assessed by ultrasonography. Data were collected by chart review, nutritional evaluation and laboratory tests and analyzed by Fisher, Wilcoxon-Mann-Whitney tests, multiple linear and log binomial regression. Results Twenty-eight patients (mean age 13.9 years, SD 3) were enrolled. The prevalence of subclinical atherosclerosis was 32% (95% CI 14.8, 49.4). The mean CIMT was 0.43 ± 0.035 mm. The most common traditional risk factors observed were dyslipidemia (82.1%), uncontrolled hypertension (14.2%), obesity (14.3%), and poor diet (78.6%). Uncontrolled hypertension (p = 0.04), proteinuria (p = 0.02), estimated glomerular filtration rate < 75 ml /min/1.73 m2 (p = 0.02) and SLEDAI-2 K > 5 (P = 0.04) were associated with subclinical atherosclerosis. SLEDAI-2 K > 5 maintained association with CIMT after adjusting for control variables. Conclusion Subclinical atherosclerosis is frequently observed in cSLE, mainly in patients with moderate to severe disease activity.

Objectives: Vaccination of systemic lupus erythematosus patients with non-live vaccines may decrease vaccine-preventable infections and mortalities. In the present study, we aimed to compare the immunogenicity and safety of inactivated hepatitis A vaccination in childhood-onset systemic lupus erythematosus and healthy subjects. Methods: A total of 30 childhood-onset systemic lupus erythematosus and 39 healthy participants who were seronegative for hepatitis A received two doses of the hepatitis A vaccine in a 0- and 6-month schedule. Hepatitis A virus (HAV) IgG antibodies were measured before vaccination and 7 months after the vaccination. Results: Although anti-HAV IgG antibody titers after vaccination were found to be somewhat lower in children with systemic lupus erythematosus than that of the healthy subjects ( p < 0.05), the difference in seroconversion rate was insignificant between childhood-onset systemic lupus erythematosus patients ( n = 24/30, 80%) and healthy controls ( n = 33/39, 84.6%). There was no increase in median Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K scores and anti-ds DNA levels after the vaccination procedure. Seroconversion rates in childhood-onset systemic lupus erythematosus patients were not affected by medication, high disease activity (SLEDAI-2K >6) and anti-ds DNA positivity. None of the patients experienced any flare or adverse reaction throughout the study. Conclusions: According to these results, we conclude that inactivated hepatitis A vaccine is safe and well tolerated in childhood-onset systemic lupus erythematosus patients, with no adverse events or increase in activity. Immunogenicity to the hepatitis A vaccine was adequate, with a seropositivity rate of 80%.

Background : Low level of vitamin D impact the disease activity and the degree of fatigue in SLE patients. This study aims to determine the effect of vitamin D supplementation on disease activity and fatigue condition in Systemic Lupus Erythematosus (SLE) patients with hipovitamin D.Methods: We performed an open clinical trial. Subjects were randomized into two different groups (supplementation or placebo) using simple random sampling. The treatment group got vitamin D3 softgel/ cholecalciferol 1200 IU/day or 30 mg/day, while the control group gotplacebo for 3 months. SLEDAI scores and FSS scores were calculated at pre and posttreatment.Results: There were 20 subjectsfor supplementation group and 19 subjects in the placebo group. From this study, before and after treatment, we found a significant difference of mean level of vitamin D in supplementation group (p=0.000), and no significant difference inpatients with placebo (p=0.427). Moreover, from the SLEDAI score analysis, observed a significant difference bothin the supplemented group (p=0.000) and the placebo group (p=0.006). FSS scores significantly different in the supplemented group (p=0.000). Incorrelation test,there was a negative correlation (r=-0763) between vitamin D level and disease activity (SLEDAI), and both showing stastistical significance between thepre supplementation (p=0.000) and post supplementation (r=-0846; p=0.000). Similarly to theFSS scores, there was a meaningfulnegative correlation (r=-0.931, p=0.000) between the level of vitamin D with FSS scores pre and post supplementation (r=-0.911; p= 0.000). Furthermore, there was a significant correlation between disease activity (SLEDAI) pre supplementation with fatigue condition pre supplementation (r=0.846; p = 0.000) and postsupplementation (r=0.913; p= 0.000).Conclusion: The supplementation of vitamin D 1200 IU per day in patients with SLE improve disease activity and degree of fatigue. Keywords: vitamin D, disease activity, fatigue, SLE
