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.

Abstract Background Patients with systemic lupus erythematosus (SLE) often experience anxiety and depression. Recent studies have shown involvement of intestinal dysbiosis in SLE and also psychosomatic disorders. However, there are no reports on the gut microbiota profile of patient with both conditions: SLE and anxiety or depression. We aimed to study gut microbiota profiles among SLE patients with gastrointestinal symptoms and anxiety or depression by sequencing V3–V4 region of the 16S rRNA gene from the stool samples. Results Of the 41 SLE patients who participated in the study, 53.66% had anxiety and 14.63% had depression. We found a higher proportion of Bacteroidetes and lower diversity indices in patients with anxiety than in those without anxiety. We also found a higher proportion of Bacteroidetes and lower Firmicutes/Bacteroidetes ratios and diversity indices in patients with depression than in those without depression. Moreover, compared to other groups, patients with symptoms of both anxiety and depression had the highest proportion of Bacteroidetes and lowest proportion of Firmicutes, Firmicutes/Bacteroidetes ratios, and diversity indices. Further analysis showed that there was a significant correlation between the proportion of Bacteroides and the anxiety score (r = 0.349; p = 0.03) as well as with lupus activity (r = 0.36; p = 0.02). There was also significant correlation between diversity indices and lupus activity (r= -0.34; p = 0.03 for Chao1 index, r= -0.38; p = 0.01 for Shannon index, and r= -0.33; p = 0.03 for richness index). Conclusions SLE patients with both anxiety and depression showed more unfavorable gut dysbiosis parameter compared to SLE patients with only anxiety or depression and SLE patients without anxiety or depression. There was positive correlation between proportion of Bacteroides and lupus disease activity and negative correlation between diversity indices and lupus disease activity.

Lupus Disease Activity

Leptin levels are increased in patients with systemic lupus erythematosus (SLE) but little is known on how this correlates with several disease characteristics including the frequency of regulatory T cells (Tregs). Here we compared serum leptin levels with frequency of circulating Tregs in 47 lupus patients vs. 25 healthy matched controls. Correlations with lupus disease activity were also analyzed, as well as Treg proliferation potential. It was found that leptin was remarkably increased in SLE patients as compared to controls, particularly in SLE patients with moderate and severe active SLE, and the increase correlated with disease activity. Importantly, increased leptin in lupus patients inversely correlated with the frequency of Tregs but not in controls, and leptin neutralization resulted in the expansion of Tregs ex vivo. Thus, hyperleptinemia in lupus patients correlates directly with disease activity and inversely with Treg frequency. The finding that leptin inhibition expands Tregs in SLE suggests possible inhibition of this molecule for an enhanced Treg function in the disease.

Lupus Disease Activity

Systemic lupus erythematosus (SLE) patients are at high risk of herpes zoster. Previously, we found increased immunoglobulin (Ig)G levels against varicella-zoster virus (VZV) in SLE patients compared to controls, while antibody levels against diphtheria and cellular immunity to VZV were decreased. We aimed to test our hypothesis that increased VZV-IgG levels in SLE result from subclinical VZV reactivations, caused by stress because of lupus disease activity or immunosuppressive drug use. Methods Antibody levels to VZV (IgG, IgA, IgM), total IgG and VZV-DNA were longitudinally determined in the serum of 34 SLE patients, using enzyme-linked immunosorbent assay and polymerase chain reaction. Clinical data were retrieved from medical records. Reactivation of VZV was defined as an at least fivefold rise in VZV-IgG or presence of VZV-IgM or VZV-DNA. Generalized estimating equations (GEE) were used to longitudinally analyse associations between antibody levels, lupus disease activity and medication use. Systemic Lupus Erythematosus Disease Activity Index, anti-double-stranded DNA and complement levels were used as indicators of lupus disease activity. Results A VZV reactivation was determined in 11 patients (33%). In at least five of them, herpes zoster was clinically overt. No association between SLE disease activity or medication use and VZV-specific antibody levels was found. There was a weak association between total IgG and VZV-IgG. Conclusions Our results indicate that increased VZV-IgG levels in SLE do not result from frequent subclinical VZV reactivations, and are not associated with lupus disease activity. Increased VZV-IgG can only partially be explained by hypergammaglobulinaemia.
