Therapeutic Decisions

Objective.To describe clinical phenotypes in neuropsychiatric systemic lupus erythematosus (NPSLE).Methods.Data were prospectively collected in the Leiden NPSLE referral clinic, where patients suspected of having NPSLE are assessed in a standardized multidisciplinary manner. In consensus meetings, all medical specialists agreed on therapeutic strategy based on the suspected pathogenetic mechanism of NPSLE in the individual patient. An algorithm illustrates the process of decision-making during the consensus meeting. Clinical phenotypes are described, classified by pathogenetic mechanism.Results.One hundred consecutive patients were evaluated, of whom 71 had SLE (29 patients did not fulfill ≥ 4 American College of Rheumatology criteria) and 46 had NPSLE. Primary NPSLE was diagnosed in 38 patients (53%) and could be differentiated in 21 patients (55%) with inflammatory NPSLE who were advised on immunosuppressive therapy, 12 patients (32%) with ischemic NPSLE who were advised on anticoagulant therapy, and 5 patients (13%) with undefined NPSLE who were advised symptomatic treatment only. Cognitive dysfunction and higher level of disease activity were associated with inflammatory NPSLE. Although presence of immunoglobulin G anticardiolipin antibodies and abnormalities on magnetic resonance imaging (MRI) were associated with ischemic NPSLE, abnormalities on MRI lacked specificity to distinguish phenotypes. A history of renal disease and use of corticosteroids were associated with secondary NPSLE.Conclusion.We describe multidisciplinary consensus as a standard for diagnosing and defining phenotypes in NPSLE. These phenotypes show specific characteristics, which can be used to support diagnosis and guide therapeutic decisions. Clinical phenotyping and selection of patients becomes increasingly important when advances in experimental science lead to new targets for therapy in NPSLE.

Abstract Aim: TO assess the effects of rituximab (RTM) therapy on clinical and morphologic activity of lupus nephritis (LN). Material and methods: The study included 45 patients with confirmed diagnosis of systemic lupus erythematosus (SLE), unaffected by previously received standard therapy with glucocorticoids (GCs) and cytostatics. The disease activity was assessed using Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI 2K); to assess the LN activity we used the SLICC RA/RE index. Forty-five patients with LN were given puncture renal biopsy prior to prescribing RTM; 16 patients had repeated renal biopsy 1 year and more after beginning the anti-B-cell therapy. LN was graded histologically in accordance with the WHO classification (2003) with indices of activity (AI) and chronicity (CI). Results: The predominant number of patients had class III - IV of LN. The repeated renal biopsies demonstrated that LN had undergone a transition into a more favourable morphologic class, which was associated, in most of these cases, with a positive therapeutic effect. The follow-up dynamics showed a statistically significant reduction of AI (p=0.006), and no statistically significant changes in the CI (p = 0.14). Conclusion: The long-term follow-up in the study has showed that repeated courses of anti-B-cell therapy with RTM have a positive effect both on SLE activity and generally on the renal process. The reduction of the morphologic class of LN as assessed in the repeated renal biopsies is a convincing proof for this. Eleven out of 16 patients experienced transition of the morphologic class into a more favourable type, which in most cases was combined with lower AI (p = 0.006). We found no evidence of increase in the CI (p = 0.14).

A Prospective Study

ABSTRACT Nucleosomes are the dominant autoantigens in patients with systemic lupus erythematosus (SLE), and immune complexes involving nucleosomes are the major cause of tissue damage. The activity of DNase I, the enzyme responsible for nucleosome degradation, has been found to be decreased in patients with SLE. However, it is not known whether DNase activity is a clinically useful parameter. The aim of our study was to assess DNase activity in a prospective study of 113 patients with SLE in relation to disease activity and organ involvement. We included two control groups: 9 patients with undifferentiated connective tissue disease (UCTD) and 14 healthy individuals. DNase activity was found to be lower in patients with SLE (63.75% ± 12.1%) than in the controls (81.3% ± 9.25%) (P < 0.001). DNase activity in patients with UCTD (64.9% ± 18.2%; P = 0.854) did not differ from that in patients with SLE. Patients with SLE had higher antinucleosome antibody titers (356.3 ± 851) than the controls (1.44 ± 2.77; P < 0.01) or UCTD patients (39.9 ± 57.7; P < 0.01). In addition, samples positive for antinucleosome antibodies displayed low levels of DNase activity. Within the SLE group, the presence of renal disease had no impact on DNase activity or antinucleosome antibody titers. Also, the SLE disease activity index showed no correlation with DNase activity. In a longitudinal study of six SLE patients, DNase activity did not follow disease activity or autoantibody titers. Our results confirm that serum DNase activity is decreased in patients with SLE, but we conclude that it is not a clinically useful parameter for the prediction of flare-ups of disease or renal involvement.

Objective.In patients with systemic lupus erythematosus (SLE), evidence suggests that most vaccines (except live-virus vaccines) are safe, although antibody response may be reduced. This substudy from the phase III, randomized, double-blind, placebo-controlled BLISS-76 trial evaluated the effects of belimumab on preexisting antibody levels against pneumococcal, tetanus, and influenza antigens in patients with SLE.Methods.In BLISS-76, patients with autoantibody-positive, active SLE were treated with placebo or belimumab 1 or 10 mg/kg every 2 weeks for 28 days and every 28 days thereafter, plus standard SLE therapy, for 76 weeks. This analysis included a subset of patients who had received pneumococcal or tetanus vaccine within 5 years or influenza vaccine within 1 year of study participation. Antibodies to vaccine antigens were tested at baseline and Week 52, and percentage changes in antibody levels from baseline and proportions of patients maintaining levels at Week 52 were assessed. Antibody titers were also assessed in a small number of patients vaccinated during the study.Results.Consistent with preservation of the memory B cell compartment with belimumab treatment, the proportions of patients maintaining antibody responses to pneumococcal, tetanus, and influenza antigens were not reduced. In a small group receiving influenza vaccine on study, antibody responses were frequently lower with belimumab, although titer levels were > 1:10 in all patients treated with 10 mg/kg and in the majority treated with 1 mg/kg.Conclusion.Treatment with belimumab did not affect the ability of patients with SLE to maintain antibody titers to previous pneumococcal, tetanus, and influenza immunizations.

Echocardiographic Findings

Background:Systemic lupus erythematosus (SLE) is a chronic and autoimmune disease characterized by systemic involvement. Patients with SLE have accelerated atherosclerosis, resulting in an up to nine-fold increased risk of cardiovascular disease, compared to the general population (1), being the leading cause of death for these patients. Speckle tracking echocardiography (STE) is an accurate technique to estimate myocardial function and deformation.Objectives:This study aims to determine the association between echocardiographic findings and the presence of antibodies in SLE patients.Methods:This was a cross-sectional and observational study. A total of forty-three patients ≥18 years with a diagnosis of SLE according to EULAR/ACR 2019 criteria were included for this study. Those with a history of cardiovascular disease (myocardial infarction, cerebrovascular accident, or peripheral arterial disease) and pregnancy were excluded. Transthoracic echocardiogram was performed and reviewed by 2 board-certified cardiologists, in all study subjects. Blood samples obtained from all patients were analyzed for the following: anti-nuclear antibodies (ANA), anti, SSA/Ro, SSB/La antibodies, anti-cardiolipin antibodies (IgA, IgM, IgG), and complement levels. Distribution was evaluated with the Kolmogorov-Smirnov test. Correlations between numerical variables were done using Spearman’s rho, considering two-tailed p-values <0.05 as statistically significant.Results:The 39 female patients (90.7%) and 4 male patients (9.3%) had a mean age of 35.5 ± 12.0 years and a median disease duration of 72 months (14-132). At the time of inclusion, 90.7% of the patients were being treated with glucocorticoids and antimalarials. Concerning traditional cardiovascular risk factors; 20.9% of the patients had hypertension, 7.0% had dyslipidemia, 2.3% had diabetes mellitus and 18.6% were active smokers. Correlations between echocardiographic findings and antibodies are shown in Table 1. We found a moderate positive correlation between global circumferential strain and IgA anticardiolipin antibody (r=0.507, p=0.002), a low positive correlation in left ventricular ejection fraction with anti-Ro (r=0.397, p=0.012) and anti-La (r=0.397, p=0.012) and a low positive correlation between TAPSE and C3 levels (r=0.396, p=0.013).Conclusion:There is an association between anticardiolipin antibody titers, anti-Ro, and anti-La with echocardiographic alterations. All SLE patients especially those who had positive antibodies should be screened for the presence of structural cardiac abnormalities. STE can be helpful as a noninvasive diagnostic tool, that could result in earlier treatment and prognosis.References:[1]Hesselvig JH, Ahlehoff O, Dreyer L, et al.
