Calprotectin Level

Background:Serum calprotectin, also known as MRP8/14 or S100A8/A9, has gained attention in recent years as a candidate biomarker in inflammatory diseases like SLE.1 Proteins of the complement pathway (serum C3 and C4) are linked to the pathogenesis of SLE and their levels have been measured as a means to assess the disease activity.2Objectives:[1]To study the relation of serum complement and serum calprotectin levels to disease activity in SLE[2]To study the relation between serum complement and serum calprotectin level in SLEMethods:Our study was a hospital based observational study conducted in a tertiary care centre in North-East India during the period of June 2019 to May 2020. A total of 102 patients of SLE were taken up for the study. Disease activity was assessed using SLEDAI-2K scores and serum calprotectin level was measured by ELISA. Serum C3 level was assessed by Nephelometric and C4 level by Turbidimetric immunoassay. The statistical significance was fixed at 5% level of significance (p<0.05) for all analysis.Results:Our study found a predominantly female population (Female: Male ratio 24.5: 1) with majority of the patients (49.02%) in the 30-39 years age group. Higher calprotectin levels were seen in patients with higher disease activity (SLEDAI) and this relation was statistically significant (r=0.84, p<0.001). There was significant negative correlation between disease activity (SLEDAI) and serum C3 (r=-0.35, p<0.001) and serum C4 (r=-0.4, p<0.001) level. There was a significant negative correlation between complement levels and serum calprotectin levels (r=-0.53, p<0.001).Conclusion:We found a significant positive correlation between serum calprotectin level and disease activity with a significant negative correlation between complement level and disease activity in SLE patients. There was a significant negative correlation between serum complement and serum calprotectin levels. These findings suggest serum calprotectin levels could be a substantial addition in the existing diagnostic array of tools in assessing lupus disease activity.References:[1]García-Arias M, Pascual-Salcedo D, Ramiro S, Ueberschlag ME, Jermann TM, Cara C, et al.

: Systemic Lupus Erythematosus (SLE) has a profound impact on quality of life. Objective: The objective of this study was to explore the quality of life among Egyptian SLE patients and to assess its relationships with demographic and clinical features. Methods: One hundred sixty-four SLE patients were recruited for this study. Demographic information; clinical parameters; disease activity, as evaluated by the systemic lupus erythematosus Disease Activity Index; and organ damage, as assessed by the systemic lupus international Collaborative Clinics/American College of Rheumatology Damage Index, were reported. Quality of life was assessed with a quality of life questionnaire specifically designed for patients with systemic lupus erythematosus; the questions are grouped in the following six domains: physical function, sociooccupational activities, symptoms, treatment, mood, and self-image. Higher values indicate poorer quality of life. Conclusion: Poor quality of life among Egyptian SLE patients and disease activity are strongly related to impaired lifestyles in these patients.

Abstract Background Systemic lupus erythematosus (SLE) patients often suffer hand function limitations even in the absence of symptoms related to joint or tendon disorders. Recent researches reported the presence of ultrasonographic (US) subclinical synovitis and tendon involvement in asymptomatic patients. We aimed to assess US patterns in SLE patients and determine their relationship with clinical assessment, disease activity and hand functional status using handheld dynamometry. Results We assessed 30 SLE patients (60 hands) using US; 21 (70%) patient had synovial hypertrophy, 8 (26%) showed a power Doppler (PD) activity, 6 (20%) had erosions and 11 (36.6%) had tendon US abnormality. Both patients with hand arthralgia/arthritis (symptomatic) and patients without arthralgia/arthritis (asymptomatic) had a statistically insignificant difference regarding the global synovitis score (p = 0.2) and disease activity (p = 0.3). However, the symptomatic group had a significantly increased number of joints with effusion (p = 0.04) and tendons involved (p = 0.04). The mean grip strength had a significant negative correlation with SLEDAI-2 K score (rs = − 0.4, p = 0.02) in the total patient group. In the asymptomatic group, a negative correlation was found between both mean grip (rs = − 0.5, p = 0.04) and pinch strength (rs = − 0.6, p = 0.01) with PD index, and mean pinch strength with the Jaccoud’s arthropathy index (rs = − 0.49, p = 0.05). Conclusions SLE patients may have higher subclinical synovitis, erosions and tendon involvement than expected, which may in turn reduce hand grip and pinch strength. Disease activity may also have a negative impact on the hand grip functional strength.

Background: Lupus nephritis (LN) is one of the most common and serious manifestations of systemic lupus erythematosus (SLE) that causes significant morbidity and mortality. Certain biomarkers for LN are sometimes able to assess treatment response in lupus nephritis. This study aimed to compare serum complement levels (C3 and C4) as markers of treatment response of LN and their relation to the LN class in renal biopsy. Methods: This prospective observational study was conducted in the Department of Nephrology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2018 to August 2019. Twenty seven patients who were diagnosed with LN after kidney biopsy were included in this study. Serum complement levels (C3 and C4), 24 hours urinary total protein (24-hr UTP) and anti-double-stranded DNA (anti-ds DNA) were measured in all patients at baseline, 3 months and 6 months after treatment initiation. These biomarker values before and after treatment were compared between the proliferative and non-proliferative LN patients. Results: Serum C3 levels were significantly different between patients with proliferative LN (Class III and Class IV) and non-proliferative LN (Class V) at baseline (0.47 ± 0.32 g/l versus 0.89 ± 0.43 g/l, p=0.009) and levels changed significantly 6 months after treatment initiation (p<0.001) and likewise for serum C4 levels (0.10 ± 0.06 g/l versus 0.24 ± 0.26 g/l, p=0.040). The values of 24-hr UTP and anti-ds-DNA were significantly different 6 months after treatment with p value <0.05 in both groups but C3 (p<0.001) and renal Systemic Lupus Erythematosus Disease Activity Index (rSLEDAI) (p<0.001) were only significant in the proliferative group. On the other hand, after 6 months treatment, C4 levels became relatively higher but that was not significant in both groups (p>0.05). Conclusion: After 6 months of treatment, serum C3 and C4 levels increased towards normal in both LN groups. Serum C3 and C4 levels in patients with LN correlate with disease activity. Therefore, serum complement (C3 and C4) levels may be utilized as serological biomarkers for treatment response of LN. Birdem Med J 2021; 11(2): 97-102

Background Juvenile onset systemic lupus erythematosus JO-SLE patients usually exhibit a more aggressive disease course compared to adult patients. Vitamin D deficiency is proposed to be associated with increased disease activity and flares of numerous autoimmune diseases like SLE, rheumatoid arthritis, and scleroderma. Objective To evaluate the level of IL-17, IFN-γ, and 25-OH Vit D in JO-SLE patients versus healthy controls, and determine the correlation of those inflammatory mediators with SLE disease activity and damage scores. Furthermore, to analyze the relationship between 25-OH Vit D levels with the inflammatory cytokines (IFN-γ and IL-17) in JO-SLE patients. Patients and methods Fifty JO-SLE patients and 25 controls were included in this study. Clinical and laboratory data of patients at the time of the study were recorded. SLE disease activity and damage were assessed using the SLEDAI-2K disease score and SLICC damage index, respectively. Plasma 25-OH Vit D, IFN-γ, and IL-17 concentrations were determined using the human ELISA kit. Results Plasma 25-OH Vit D levels (20 ng/mL) were significantly lower in JO-SLE patients compared to (31 ng/mL) controls (P = 0.014). Plasma levels of IFN-γ and IL-17 were significantly higher (163.5 and 25.5 pg./mL) in JO-SLE patients than (68.3 and 3 pg./mL) that of controls (P = 0.016 and P = 0.013). There was a significant negative correlation between 25-OH Vit D levels and SLEDAI-2K (R= -0.431) as well as IFN-γ (R= -0.471) plasma level (P = 0.022 and P = 0.027). Conclusion IFN-γ and IL-17 were significantly higher in JO-SLE patients, while 25-OH Vit D was significantly lower compared to controls. There was a negative correlation between 25-OH Vit D and each of SLEDAI-2K and IFN-γ.

The Relationship

Abstract Background Systemic lupus erythematosus (SLE) is an autoimmune disorder associated with immunological abnormalities (Aringer et al., Arthritis Rheumatol 71:1400-1412, 2019). Vitamin D (VD) has an important role in SLE pathogenesis, as it controls cell cycle progression besides its anti-proliferative effects (Liu et al., J Cell Commun Signal 71, 2019). Determining the relationship between VD with SLE activity and lupus nephritis (LN) can establish a new role for VD in SLE management (Liu et al., J Cell Commun Signal 71, 2019). In our study, we aimed to assess the relationship between levels of VD in patients with SLE activity and with LN and to verify the relationship between VD levels with clinical and laboratory parameters in those patients, in order to assess the validity of adding serum VD level in the routine follow-up as a marker that may lead to earlier diagnosis of SLE activity and LN in adult SLE patients. Results Serum VD was significantly lower in SLE patients (3.38 ± 2.55 ng/ml) versus healthy controls (5.36 ± 2.88 ng/ml) (P < 0.002). Interestingly, serum VD was significantly lower in patient with active SLE according to SLEDAI (3.00 ± 2.27 ng/ml) versus those with inactive SLE (5.10 ± 3.19 ng/ml) (P < 0.02). Significant negative correlation was found between serum level of VD and each of mucocutaneous, malar rash, and renal manifestations. Significant negative correlation was also noticed among SLEDAI (P value = 0.01) and renal SLEDAI scores (P value = 0.021) with serum level of VD. Conclusion Low levels of VD were found to be frequent in SLE patients especially during phases of SLE activity and nephritis. Potent markers of low serum VD level in SLE patients were found to be mucocutaneous, malar rash, and LN. Our results support that VD levels could act as independent risk factors for activity and LN in SLE patients; moreover, treatment with VD supplementation could decrease the incidence of activity and nephritis in SLE patients.
