Objective. The objective of this study was to investigate the impact of disease onset age on mortality and renal survival in female SLE patients.Methods. This nationwide, population-based, retrospective cohort study used data from the National Health Insurance Research Database of Taiwan. Female patients newly diagnosed with SLE from 2001 to 2004 were identified as the study cohort. A non-SLE group was matched for age, sex and initial diagnosis date (index date) as the comparison cohort. Co-morbidities, mortality rates and end-stage renal disease (ESRD) incidences were compared among SLE patients of different onset age. Hazard ratios with a 95% CI were determined by the Cox proportional hazard model to quantify the mortality rates and ESRD incidences. Juvenile-onset, adult-onset and late-onset SLE patients were categorized according to disease onset age: <18, 18–50 and >50 years old.Results. In total, 513 juvenile-onset, 3076 adult-onset and 764 late-onset SLE patients were identified. Compared with non-SLE controls, the hazard ratios of mortality were 6.49 (95% CI 3.73, 11.32, P < 0.001) for juvenile-onset, 1.75 (95% CI 1.47, 2.08, P < 0.001) for adult-onset and 3.44 (95% CI 2.76, 4.28, P < 0.001) for late-onset SLE patients. The hazard ratios of incident ESRD were 20.28 (95% CI 12.79, 32.15, P < 0.001) for adult-onset lupus patients and 1.99 (95% CI 1.36, 2.93, P < 0.001) for late-onset patients.Conclusion. Female patients with late-onset SLE carried a higher risk of mortality than those with adult-onset disease in the presence of co-morbidities. Juvenile-onset SLE patients were at greatest risk of mortality, which is probably due to disease severity. [ABSTRACT FROM PUBLISHER]

Objective. To investigate the potential role of Th type 17 (Th17) cells and Th17-related cytokines in the pathogenesis of adult-onset Still’s disease (AOSD).Methods. The frequencies of circulating Th17 cells in 24 patients with active untreated AOSD, 16 patients with active SLE and 12 healthy volunteers were determined using intracellular cytokine staining and flow cytometry. Serum levels of Th17-related cytokines, including IL-1β, IL-6, IL-17, IL-18, IL-21 and IL-23 were measured by ELISA.Results. Significantly higher median frequencies of circulating Th17 cells were found in active untreated AOSD patients (1.01%) and active SLE patients (1.26%) than in healthy volunteers (0.12%, both P < 0.001). The frequencies of circulating Th17 cells were positively correlated with activity score (r = 0.527, P < 0.01) and serum ferritin levels (r = 0.724, P < 0.001) in AOSD patients, and correlated with SLEDAI (r = 0.663, P < 0.01) in SLE patients. Additionally, the frequencies of circulating Th17 cells were positively and significantly correlated with serum levels of IL-1β, IL-6, IL-17, IL-18, IL-21 and IL-23 in both AOSD and SLE patients. The frequencies of circulating Th17 cells and serum IL-17 levels significantly decreased after effective therapy in AOSD patients (both P < 0.001).Conclusion. Elevated frequencies of circulating Th17 cells and a positive correlation with disease activity in our AOSD patients suggest that Th17 cells contribute to the pathogenesis of this disease. Dysregulation of Th17 cells may be a common pathogenic mechanism that underlies the development of both AOSD and SLE. [ABSTRACT FROM PUBLISHER]

Objective. To determine circulating levels of CD4
+ CD25high regulatory T (Treg) cells and transforming growth factor-β (TGF-β) in patients with adult-onset Still's disease (AOSD) and to examine the associations with disease activity and clinical course of this disease. Methods. The frequencies of circulating CD4+ CD25high Treg cells in 52 active AOSD patients, 42 active systemic lupus erythematosus (SLE) patients, and 22 healthy controls (HCs) were determined using flow cytometry analysis. Levels of serum TGF-β and soluble interleukin-2 receptor (sIL-2R) were measured by enzyme-linked immunosorbent assay. Results. Significantly lower levels of circulating CD4+ CD25high Treg cells and serum TGF-β were found in AOSD patients and SLE patients than those found in HCs. Levels of circulating CD4+ CD25high Treg cells and TGF-β were inversely correlated with disease activity scores for AOSD patients and SLE patients. Circulating CD4+ CD25high Treg cell frequencies were positively correlated with serum TGF-β levels for patients with both diseases. Levels of circulating CD4+ CD25high Treg cells and TGF-β significantly increased, paralleling clinical remission and the decrease in levels of C-reactive protein and soluble interleukin-2 receptor after effective therapy in AOSD patients. AOSD patients with monocyclic course had significantly higher levels of circulating CD4+ CD25high Treg cells and TGF-β compared to those with polycyclic and chronic articular course. Conclusion. Diminished levels of circulating CD4+ CD25high Treg cells and TGF-β, and inverse correlation with disease activity in patients with AOSD and SLE might be involved in the pathogenesis of both diseases. Increased levels of circulating CD4+ CD25high Treg cells or TGF-β might be associated with a favorable clinical course in AOSD patients. [ABSTRACT FROM AUTHOR]- Published

Background: Lupus nephritis (LN) often lead to end-stage renal disease in systemic lupus erythematosus patients. This study aimed to investigate the clinical application of renal gallium-67 scans for determining renal histological parameters in LN patients. Methods: Between 2006 and 2018, 237 biopsy-proven and 35 repeat biopsies LN patients who underwent renal gallium scans before or after biopsy were included for analysis. The classification and scoring of LN were assessed according to the International Society of Nephrology/Renal Pathology Society. A delayed 48-h gallium scan was performed and interpreted by semiquantitative methods using left kidney/spine (K/S) ratio. The renal histological results were compared with gallium uptake. Results: Out of 237 participants, 180 (76%) had proliferative LN. Baseline gallium left K/S ratio was significantly higher in class IV LN as compared to class III (median (interquartile range, IQR): 1.16 (1.0–1.3), 0.95 (0.9–1.1), respectively, p < 0.001). Furthermore, changes in gallium uptake between two biopsies were positively correlated with changes activity index (r = 0.357, p = 0.035), endocapillary hypercellularity (r = 0.385, p = 0.032), and neutrophils infiltration (r = 0.390, p = 0.030) in renal pathology. Conclusions: Renal gallium uptake is associated with active inflammation in LN. Changes in renal gallium uptake positively correlated with changes in activity index in renal pathology.
