Abstract Concentrations of neopterin were measured in urine specimens from 35 patients with active and eight with inactive systemic lupus erythematosus (SLE). Compared with those of apparently healthy controls, neopterin concentrations were higher in patients with active disease (P less than 0.001) and with inactive disease (P less than 0.01), those in patients with active disease being significantly higher than those in patients with inactive disease (P less than 0.001). The correlation between the neopterin concentration and evidence of disease activity was good. All of the patients with clinically active SLE had increased neopterin, but for only 37.5% (three of eight) did the neopterin concentration exceed the upper normal limit during clinical remission. The increase in neopterin concentration did not correlate with clinical courses or severity of renal function. Moreover, serial determinations of neopterin in active SLE patients showed a rapid decrease of initially high concentration, paralleling a decline of clinical activity after initiation of medical therapy. Thus, urinary neopterin may be a useful marker for monitoring disease activity in SLE patients.

Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease that may cause morbidity and mortality by affecting multiple systems. The 10-20% of patients have juvenile onset and this cluster have may more severe kidney, neuropsychiatric or hematological involvement.Objectives:The aim of this study was to assess the clinical and laboratory characteristics, disease activity, and treatment response of patients with juvenile SLE (jSLE).Methods:This is a retrospective study involving patients between 1 July 2016 and 1 January 2020. The data of patients diagnosed with jSLE and followed up for a minimum of 6 months, were collected. The SLEDAI-2K scores at initiation and at the follow-up (1st, 3rd, 6th, and 12th months of treatment) were examined. The SLEDAI-2K score was considered to be ≤4, for disease remission status.Results:A total of 49 children were included in to the study. The female/male ratio was 4.4/1 and the median age of the patients at the diagnosis was 13 (IQR: 11.1–15.2) years. The median follow-up of patients was 19 (IQR: 12–25) month. Four of the patients were diagnosed with monogenic SLE. Two siblings were diagnosed with c3 deficiency and two were diagnosed with familial chilblain lupus. The most common clinical findings were found musculoskeletal complaints (69.4%), malar rash (51%), oral ulcers (38.8%), and fever (30.6%), respectively in over all the group. The frequency of involvement of the system and organs was as follows; mucocutaneous 77.6%, musculoskeletal 69.4%, renal 44.9%, hematological 34.7%, serous membranes 16.3%, neuropsychiatric 12.2%, respectively. All patients had anti-nuclear antibody positivity, while 46.9% had anti-ds DNA, 14.3% had anti-Sm and 8.2% had antiphospholipid antibody positivity. While all patients received hydroxychloroquine treatment, 22.4% of the patients were received were mycophenolate mofetil, 22.4% were azathioprine, 14.3% cyclophosphamide, 12.2% methotrexate and 10.2% were rituximab. The median SLEDAI-2K score was 14 (IQR: 10–18.5) at admission, besides it was found to 6 (IQR: 4–12), 4 (IQR: 2–6), 2 (IQR: 0–6) in the 1st, 6th and 12th months of treatment, respectively. While 98% of the patients had active disease at admission, 67.3% at 1 months, 32.7% at 6 months and 22.4% at 12 months still had active disease (SLEDAI-2K >4). Patients with initially high SLEDAI-2K scores had significantly lower remission rates in the first month (p=0.003). It was observed that patients with high SLEDAI-2K scores in admission were more resistant to conventional immunosuppressive treatments and the use of rituximab was more frequent in these patients. At least one major organ (renal, hematological, neurological) were affected in 57% of patients. The remission rate of these patients at 6 months was found significantly decreased compared to the others (p <0.005). Renal biopsy was performed in 21 patients (42.9%). 12 of them had type 4 lupus nephritis (LN), 5 had type 2, 2 had type 3, and 1 had type 5. It was observed that patients with renal involvement were the group that reached remission latest.Conclusion:The presence of high initial SLEDAI-2K scores and the major organ involvement have poor predictive value to achieve inactive disease.References:[1]Yee CS, Farewell VT, Isenberg DA, Griffiths B, Teh LS, Bruce IN, et al.

Systemic lupus erythematosus (SLE) is a clinically heterogeneous chronic, inflammatory autoimmune disorder. The association of MMP-7 and disease severity is still unclear. A total of 150 SLE patients and matched healthy controls were recruited for this study. Disease activity was scored according to SLEDAI (98 active and 52 inactive disease). Mean serum MMP-7 levels were significantly higher in SLE patients than controls ( p < 0.001). Patients with active disease showed higher levels (16.24 ± 6.2 ng/ml) as against inactive disease (10.50 ± 3.97 ng/ml) ( p ≤ 0.0001). Mean MMP-7 mRNA expression was significantly higher in patients (RQ = 3.16 ± 0.93) as compared to controls (RQ = 2.21 ± 0.89, p = 0.006). A positive correlation between MMP-7 levels, mRNA expression and SLEDAI score was observed ( r = 0.563, r = 0.427). The MMP-7 −181 G allele was found to be significantly higher among SLE patients ( p < 0.0001). A significant association was noted between MMP-7 −181 A/G +G/G genotypes with renal ( p = 0.0027) and CNS ( p = 0.0031) manifestations and anti-dsDNA autoantibodies ( p = 0.0312). Serum MMP-7 levels and mRNA expression were elevated in advanced stages of SLE, indicating that MMP-7 is associated with disease activity in SLE.

ObjectiveInterleukin-26 (IL-26) has a unique ability to activate innate immune cells due to its binding to circulating double-stranded DNA. High levels of IL-26 have been reported in patients with chronic inflammation. We aimed to investigate IL-26 levels in patients with systemic lupus erythematosus (SLE).MethodsIL-26 serum levels were quantified by ELISA for 47 healthy controls and 109 SLE patients previously enrolled in the PLUS study. Performance of IL-26 levels and classical markers (autoantibodies or complement consumption) to identify an active SLE disease (SLE disease activity index (SLEDAI) score &gt; 4) were compared.ResultsIL-26 levels were significantly higher in SLE patients than in controls (4.04 ± 11.66 and 0.74 ± 2.02 ng/mL; p = 0.005). IL-26 levels were also significantly higher in patients with active disease than those with inactive disease (33.08 ± 21.06 vs 1.10 ± 3.80 ng/mL, p &lt; 0.0001). IL-26 levels correlated with SLEDAI score and the urine protein to creatinine ratio (uPCR) (p &lt; 0.001). Patients with high IL-26 levels had higher SLEDAI score, anti-DNA antibodies levels, and uPCR (p &lt; 0.05). They presented more frequently with C3 or C4 complement consumption. Lastly, IL-26 showed stronger performance than classical markers (complement consumption or autoantibodies) for active disease identification.ConclusionsOur results suggest that, in addition to classical SLE serological markers, the measurement of IL-26 levels may be a useful biomarker for active disease identification in SLE patients.

ObjectivesExploring the associations between disease activity and medications with offspring birth weight, pre-eclampsia and preterm birth in systemic lupus erythematosus (SLE).MethodsData from the Medical Birth Registry of Norway (MBRN) were linked with data from RevNatus, a nationwide observational register recruiting women with inflammatory rheumatic diseases. Singleton births in women with SLE included in RevNatus 2006–2015 were cases (n=180). All other singleton births registered in MBRN during this time (n=498 849) served as population controls. Z-score for birth weight adjusted for gestational age and gender was calculated. Disease activity was assessed using Lupus Activity Index in Pregnancy. We compared z-scores for birth weight, pre-eclampsia and preterm birth in cases with inactive disease, cases with active disease and population controls.ResultsZ-scores for birth weight in offspring were lower in inactive (−0.64) and active (−0.53) diseases than population controls (−0.11). Inactive disease did not predict pre-eclampsia while active disease yielded OR 5.33 and OR 3.38 compared with population controls and inactive disease, respectively. Preterm birth occurred more often in inactive (OR 2.57) and active (OR 8.66) diseases compared with population controls, and in active compared with inactive disease (OR 3.36).ConclusionsSLE has an increased odds for low birth weight and preterm birth, amplified by active disease. The odds for pre-eclampsia is elevated in active, but not inactive disease. This calls for tight follow-up targeting inactive disease before and throughout pregnancy.

Objective.To determine whether the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) is valid in identifying patients who had a clinically important overall improvement with no worsening in other descriptors/systems.Methods.Consecutive patients with systemic lupus erythematosus with active disease who attended the Lupus Clinic between 2000 and 2012 were studied. Based on the change in the total SLEDAI-2K scores on last visit, patients were grouped as improved, flared/worsened, and unchanged. Patients showing improvement were evaluated for the presence of new active descriptors at last visit compared with baseline visit.Results.Of the 158 patients studied, 109 patients had improved, 38 remained unchanged, and 11 flared/worsened at last visit. In the improved group, 11 patients had a new laboratory descriptor that was not present at baseline visit. In those 11 patients, this new laboratory descriptor was not clinically significant and did not require a change in disease management.Conclusion.The SLEDAI-2K identifies improvement in disease activity overall without concealing clinically important worsening.

Purpose. We analyzed the prevalence, clinical correlation, and the functional significance of ALA in patients with systemic lupus erythematosus (SLE).Methods. ALA IgG was detected by indirect immunofluorescence in the serum of 130 SLE patients, 75 patients with various rheumatic diseases, and 45 healthy controls (HC).Results. The sensitivity and specificity of ALA IgG in SLE were 42.3% and 96.7%, respectively. ALA was observed in 55.6% (50/90) of patients with lymphopenia, which was significantly higher than in patients with normal lymphocytes (5/40, 12.5%;P<0.001). Patients with active SLE showed higher ALA positivity (60.9%) than those with inactive disease (24.2%;χ2= 17.925;P<0.001). ALA correlated significantly with hypocomplementemia, anti-dsDNA antibodies, and higher SLEDAI scores. The incidences of ALA in SLE patients who were seronegative for anti-dsDNA, anti-Sm, or both antibodies were 32.9% (26/79), 41.0% (43/105), and 32.4% (22/68), respectively. The ALA-positive group also had higher incidences of neuropsychiatric SLE (NPSLE) and lupus nephritis (LN). In multivariate analyses, ALA was independently associated with lymphopenia, higher SLEDAI scores, and increased risk for LN. ALA titers significantly decreased as clinical disease was ameliorated following treatment.Conclusions. ALA occurred more frequently in patients with active SLE and was independently associated with lymphopenia, disease activity, and LN.

Background Cathelicidin (LL-37), an endogenous antimicrobial peptide, has recently been involved in the pathogenesis of autoimmune diseases. To assess whether LL-37 reflects disease activity, we measured serum levels of it in systemic lupus erythematosus (SLE) patients with active and inactive disease compared to healthy controls. LL-37 was also compared between new and old cases. Moreover, the correlation of LL-37 and pro-oxidant, antioxidant balance (PAB) was measured. Methods The study population consisted of 50 SLE patients and 28 healthy controls. Of those, 39 patients had active and 11 patients had inactive disease. Serum levels of LL-37 were measured by ELISA and PAB values by a special method. Results There was no difference in levels of LL-37 between patients and healthy controls (50.9 ± 20.8 vs. 67.7 ± 43.3 ng/ml, P = 0.31). LL-37 did not correlate with SLEDAI and its items in total patients. LL-37 had a positive correlation with SLEDAI in active patients ( P = 0.01, r = 0.4). In active patients (78% of patients), multivariate regression analysis showed significant negative correlation between LL-37 and C3 ( P = 0.01, standardized beta –0.50). No difference was found in levels of PAB between patients and controls (90.4 ± 34.1 vs. 86.9 ± 25.6 HK, P = 0.4).There was no difference in the levels of PAB between patients with active and inactive disease (93.2 ± 34.1 vs. 80.2 ± 33.7 HK, P = 0.27). No correlation was found between levels of PAB and SLEDAI items and total score. However, a positive correlation between the levels of LL-37 and PAB in SLE patients was found ( r = 0.3, P < 0.01). Conclusion Based on this study, serum LL-37 and PAB did not increase in lupus compared with healthy individuals. LL-37 serum values rose in parallel with SLEDAI in active disease. Positive correlation between serum PAB and LL-37 could be a great achievement of this study that may suggest the role of antioxidants in controlling NETosis.

Objectives: Our aims were to evaluate Systemic Lupus Erythematosus (SLE) disease activity and SARS-CoV-2 specific immune responses after BNT162b2 vaccination. Methods: In this prospective study, disease activity and clinical assessments were recorded from the first dose of vaccine, until day 15 after the second dose in 126 SLE patients. SARS-CoV-2 antibody responses were measured against wild-type spike antigen while serum-neutralizing activity was assessed against the SARS-CoV-2 historical strain and variants of concerns (VOCs). Vaccine-specific T-cell responses were quantified by Interferon (IFN)-gamma; release assay after the second dose. Results: BNT162b2 was well tolerated and no statistically significant variations of BILAG and SLEDAI scores were observed throughout the study in SLE patients with active and inactive disease at baseline. Mycophenolate Mofetil (MMF) and Methotrexate (MTX) treatments were associated with drastically reduced BNT162b2 antibody-response (beta=-78; p=0.007, beta=-122; p<0.001, respectively). Anti-spike antibody response was positively associated with baseline total IgG serum levels, naive B cell frequencies (beta=2; p=0.018, beta=2.5; p=0.003) and SARS-CoV-2-specific T cell response (r=0.462; p=0.003). In responders, serum neutralization activity decreased against VOCs bearing the E484K mutation but remained detectable in a majority of patients. Conclusion: MMF, MTX and poor baseline humoral immune status, particularly: low naive B cell frequencies, are independently associated with impaired BNT162b2 mRNA antibody response, delineating SLE patients who might need adapted vaccine regimens and follow-up.

Abstract Objetives. To determine the correlation between prolactin levels and disease activity classified based on the Mexican lupus erythematosus disease systemic activity index (MEX SLEDAI).Methods. In this cross-sectional observational study, serum prolactin, age, sex, treatment, as well as manifestations of active disease were determined. Disease activity was evaluated using the Mexican Systemic Lupus Erythematosus Activity Index (MEX-SLEDAI). The correlation of MEX-SLEDAI with prolactin was determined using the Spearman correlation coefficient. The significance of differences between continuous variables was determined with the non-paired Student’s t test and the significance of differences between categorical variables was determined with Chi-square test.Results. 55 patients were included, 10 (18.1%) had MEX-SLEDAI ≥ 7 and 45 (81.8%) less than 7. A positive correlation was found with a Spearman rho 0.387 (p = 0.004) between the MEX-SLEDAI and the levels serum prolactin. Subjects with active disease and hyperprolactinemia had 80% manifestations at the renal level (p = 0.001).Conclusion. There is significant correlation between prolactin levels and disease activity. Hyperprolactinemia were detected in patients with renal activity as well as those with MEX-SLEDAI ≥ 7.

Objective The objective of this article is to investigate whether the aberrant expression of collagen triple helix repeat containing-1 (CTHRC1) from patients with systemic lupus erythematosus (SLE) could contribute to the pathogenesis of lupus. Methods We divided SLE patients into active groups (Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score ≥ 6) and inactive groups (SLEDAI score < 6). Serum concentrations of CTHRC1, interferon alpha, interleukin (IL)-28A and IL-28B were determined using an enzyme-linked immunosorbent assay in a group of 40 patients with SLE. Results were compared with those from 23 healthy controls. Results Serum CTHRC1 protein levels were higher in patients with SLE compared with healthy controls. Patients with active disease displayed higher CTHRC1 levels compared with those with inactive disease as well. There was a positive association between serum CTHRC1 levels and SLEDAI and erythrocyte sedimentation rate, and a negative correlation with complement 3 and 4. Moreover, serum CTHRC1 levels were higher in SLE patients with arthritis and anemia compared with patients without the above-mentioned manifestations. Conclusions These findings indicate CTHRC1 probably plays an important part in the pathogenesis of SLE, and is positively associated with disease activity, while it also likely refers to the development of arthritis and anemia in SLE. Therefore, CTHRC1 may provide a novel research target and shed new light on the pathogenesis and therapy of SLE.
