Lupus Disease Activity

Objective.Adjusted mean Systemic Lupus Erythematosus Disease Activity Index (SLEDAI; AMS) measures lupus disease activity over time. Our aim was to determine optimal visit frequency for calculating AMS.Methods.Patients followed monthly for 12 consecutive visits were included. AMS was calculated using all of the SLEDAI 2000 (AMSGOLD using all 12 visits), only quarterly visits (AMS3, using visits 3 months apart), semiannual visits (AMS6, using first, middle, and last visits only), and annual visits (AMS12, using only the first and last visits). Comparisons of AMS3, AMS6, and AMS12 with AMSGOLD are made using descriptive statistics.Results.Seventy-eight patients were included (92% women, mean age at SLE diagnosis 30.1 yrs and at study start 46.2 yrs). The mean (SD) AMSGOLD for the entire year was 2.05 (1.66), for AMS3 1.99 (1.65), for AMS6 2.12 (1.87), and for AMS12 2.08 (1.83). Mean (SD) of the absolute differences with AMSGOLD: for AMS3 0.29 (0.33), for AMS6 0.45 (0.59), and for AMS12 0.61 (0.58). Differences that were < 0.5 were considered minimal while those ≥ 1 were deemed important. Comparing AMSGOLD to AMS3, 82% of the differences were minimal and 3% were important. When comparing to AMS6, 68% were minimal and 10% were important, while comparing to AMS12, 50% were minimal and 21% were important.Conclusion.Usual clinic visits occurring quarterly offer a good estimation of disease activity over a 1-year period and are preferred over semiannual and annual visits.

Neuropsychiatric systemic lupus erythematosus (NPSLE) is an important cause of morbidity and mortality. We undertook this observational retrospective study of patients with NPSLE who had brain magnetic resonance imaging (MRI) to determine the indications for MRI and the correlation of clinical and laboratory findings with MRI. We identified 83 NPSLE patients (84.3% women) seen at Inkosi Albert Luthuli Central Hospital in Durban, South Africa, between June 2003 and May 2017. The mean age at SLE diagnosis was 26.24 ± 12.81 years and the median interval to NPSLE was 11.0 (interquartile range, 4.0–39.0) months. The most common indications for MRI were seizures (45.8%), psychosis (18.1%) and cerebrovascular disease (18.1%). The MRI was abnormal in 68 (81.9%) with small-vessel disease in 65 (78.3%) and large-vessel disease in eight (9.6%). The small-vessel abnormalities were white-matter hyperintensities (WMH) (59.0%), atrophy (55.4%) and lacunae (4.6%). Our patients had high disease activity at NPSLE. Cerebrovascular disease was associated with an abnormal MRI ( p = 0.018) and large-vessel disease ( p = 0.014) on MRI. Our NPSLE patients were younger and had high disease activity, and seizures were more common compared with other studies. The most common MRI abnormalities were WMH and cortical atrophy, in agreement with other studies.

Objective.The pathogenesis of systemic lupus erythematosus (SLE) involves complement activation. Activation of complement through the classical pathway (CP) is well established. However, complement activation through pattern recognition not only happens through the CP, but also through the lectin pathway (LP). We investigated the hypothesis that the LP is activated in SLE and involved in the pathogenesis of the disease.Methods.Using immunoassays developed in-house, we measured concentrations of LP proteins in a cohort of 372 patients with SLE and 170 controls. We estimated complement activation measuring total C3, and investigated whether LP protein concentrations were associated with complement activation and disease activity. Protein changes and disease activity over time were assessed in a cohort of 52 patients with SLE followed with repeated samples over a 5-year period.Results.Concentrations of LP proteins in SLE were altered compared with controls. The differences observed in LP proteins associated with complement activation were reflected by a decrease in total C3. The pattern recognition molecules (M-ficolin, CL-L1, and CL-K1), the serine protease (MASP-3), and the associated protein (MAp19) displayed a negative correlation with disease activity. Changes in MASP-2 concentrations over time correlated significantly with increased disease activity. Association between active proteinuria and serum concentration was observed for MASP-3 and MAp19.Conclusion.In patients with SLE, we measured specific changes in LP proteins that are associated with complement activation and disease activity, indicating that the LP is activated in patients with SLE. These novel findings substantiate the involvement of the LP in SLE.

Aim The aim of this study was to identify factors predictive of serious infections over time in patients with systemic lupus erythematosus (SLE). Methods A multi-ethnic, multi-national Latin American SLE cohort was studied. Serious infection was defined as one that required hospitalization, occurred during a hospitalization or led to death. Potential predictors included were sociodemographic factors, clinical manifestations (per organ involved, lymphopenia and leukopenia, independently) and previous infections at baseline. Disease activity (SLEDAI), damage (SLICC/ACR Damage Index), non-serious infections, glucocorticoids, antimalarials (users and non-users), and immunosuppressive drugs use; the last six variables were examined as time-dependent covariates. Cox regression models were used to evaluate the predictors of serious infections using a backward elimination procedure. Univariable and multivariable analyses were performed. Results Of the 1243 patients included, 1116 (89.8%) were female. The median (interquartile range) age at diagnosis and follow-up time were 27 (20–37) years and 47.8 (17.9–68.6) months, respectively. The incidence rate of serious infections was 3.8 cases per 100 person-years. Antimalarial use (hazard ratio: 0.69; 95% confidence interval (CI): 0.48–0.99; p = 0.0440) was protective, while doses of prednisone >15 and ≤60 mg/day (hazard ratio: 4.18; 95 %CI: 1.69–10.31; p = 0.0019) and >60 mg/day (hazard ratio: 4.71; 95% CI: 1.35–16.49; p = 0.0153), use of methylprednisolone pulses (hazard ratio: 1.53; 95% CI: 1.10–2.13; p = 0.0124), increase in disease activity (hazard ratio: 1.03; 95% CI: 1.01–1.04; p = 0.0016) and damage accrual (hazard ratio: 1.22; 95% CI: 1.11–1.34; p < 0.0001) were predictive factors of serious infections. Conclusions Over time, prednisone doses higher than 15 mg/day, use of methylprednisolone pulses, increase in disease activity and damage accrual were predictive of infections, whereas antimalarial use was protective against them in SLE patients.
