Low apolipoprotein M serum levels correlate with Systemic lupus erythematosus disease activity and apolipoprotein M gene polymorphisms with Lupus.

ABSTRACT: Sequence variation in gene promoters is often associated with disease risk. In this study, we tested the hypothesis that common promoter variation in the APOM gene is associated with systemic lupus erythematosus (SLE) risk and SLE-related clinical phenotypes in a Chinese cohort. Meanwhile, we investigated the expression of apolipoprotein M (APOM) in the serum of patients with systemic lupus erythematosus (SLE) and its relationship with disease activity.We used a case-control design and genotyped 52 SLE patients and 52 healthy controls for 19 APOM promoter single nucleotide polymorphism (SNP) (rs113947529, rs1143030, rs114826514, rs116715239, rs12525463, rs1266078, rs2273612, rs28432254, rs34490746, rs4947251, rs55880811, rs707921, rs74890500, rs75629491, rs76611345, rs76794541, rs805264, rs805297, rs9267528). Genotyping was done by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The blood serum concentration of APOM was measured by an enzyme-linked immunosorbent assay in SLE patients and controls.The average concentration of APOM in serum was significantly lower in SLE patients compared to controls and APOM levels in SLE patients with positive anti-dsDNA antibodies were dramatically lower than that of patients with negative anti-dsDNA antibodies (P = 0.011). It was interesting that APOM levels correlated with systemic lupus erythematosus disease activity index (SLEDAI) scores (r = -0.396, P = 0.004). No association between APOM and SLE susceptibility was detected in our Han Chinese cohort.Our results demonstrated that lower APOM levels in SLE patients and correlated with disease activity.

Project description:Correlation between soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) concentration, VEGFR1 gene polymorphisms and systemic lupus erythematosus (SLE) risk remains unclear. The present case-control study comprised 254 SLE patients, 385 other rheumatic diseases patients and 390 healthy controls. Serum levels of sVEGFR-1 were detected by enzyme-linked immunosorbent assay. Seven VEGFR1 genetic variants (rs2296188, rs9943922, rs2296283, rs7324510, rs9554322, rs9582036, rs9554320) were genotyped by KASP. Serum levels of sVEGFR-1 were up-regulated in SLE and positively correlated with disease activity. Furthermore, serum sVEGFR-1 presented a distinctive elevation in SLE in comparison with other rheumatic diseases. Frequencies of allele T of rs2296283 and allele G of rs9554322 were significant lower in SLE patients (P?=?0.003, P?=?0.004). Frequencies of genotypes TT of rs2296188 and rs2296283 were declined in patients compared with healthy controls (P?=?0.039, P?=?0.033). CC genotype of rs7324510 and rs9582036 was negatively correlated with SLE risk (OR?=?0.538, OR?=?0.508). Distribution of GG, GC, GG?+?GC genotypes of rs9554322 were different between SLE patients and healthy controls (P?=?0.027, P?=?0.036, P?=?0.010). Moreover, frequency of TC genotype of rs7324510 was higher in SLE patients with lupus headache (?2?=?9.924, P?=?0.039) and frequency of TC genotype of rs9943922 was lower in patients with cylindruriain (?2?=?7.589, P?=?0.026). Frequencies of allele C of rs7324510 and allele T of rs9943922 were decreased in SLE patients with cylindruria and hypocomplementemia, respectively (?2?=?4.195, P?=?0.041, ?2?=?3.971, P?=?0.046). However, frequency of allele C of rs9554322 was increased in SLE patients with pyuria (?2?=?11.702, P?=?0.001). In addition, SLE patients carrying GG, GC, CC genotypes for rs9554322 had higher levels of serum sVEGFR-1. In conclusion, serum sVEGFR-1 was elevated in SLE patients and may be a disease marker. VEGFR1 gene polymorphisms related to risk of SLE in a Chinese Han population.

Project description:BackgroundApolipoprotein M (apoM) is a 25-kDa apolipoprotein present in 5% of high-density lipoprotein (HDL) particles. It is suggested to be anti-atherogenic and to play a key role in sustaining endothelial barrier integrity. SLE patients have increased cardiovascular disease risk, and we aimed to investigate if apoM levels reflect endothelial function in SLE. Since apoM plasma levels decrease during inflammatory conditions, our aim was also to determine the impact of SLE disease activity on apoM plasma levels.MethodsPlasma concentrations of apoM were measured by ELISA in two patient groups with systemic lupus erythematosus (SLE) and in 79 healthy control individuals. In patient group I (n = 84), evaluation time points were selected with the objective to include a wide range of clinical and laboratory variables reflecting disease activity which was measured as SLEDAI. In patient group II consisting of 140 consecutive patients, endothelial function was measured by a finger plethysmograph. A low Reactive Hyperemia Index (RHI) value indicates endothelial dysfunction.ResultsSLE patients had decreased levels of apoM compared to healthy controls (p < 0.01), with apoM levels correlating inversely with SLEDAI (r = - 0.31, p < 0.01) as well as with levels of CRP (r = - 0.26, p = 0.02) and positively with levels of C3 (r = 0.29, p < 0.01). ApoM levels were particularly low in patients with active disease from the kidney and skin and in patients with leukopenia or positive anti-dsDNA antibody test (p < 0.05). ApoM levels correlated with RHI values in young SLE patients (r = 0.32, p = 0.01), consistent with the important role of apoM in regulating endothelial integrity.ConclusionsApoM levels may be regulated by SLE-related inflammatory processes and could be a marker of disease activity and endothelial dysfunction, in particular in young SLE patients. Further studies are needed to investigate the predictive value of apoM in the development of a cardiovascular disease.
