Background: Tumor necrosis Factor-α (TNF-α) is encoded and controlled by TNF-α gene, which is involved in rheumatoid arthritis (RA) susceptibility. This research aimed to identify genetic variations of TNF-α (G308A) and to establish its association with inflammatory markers in Rheumatoid Arthritis predisposition. Methods: In the present study, fifty RA patients and fifty volunteers were involved and evaluated for the C-reactive protein, rheumatoid factor, and TNF-α were estimated by ELISA, Erythrocyte Sedimentation Rate (ESR) by Wintergreen method and for TNF-α-308 G>A polymorphism by polymerase chain reaction with amplification refractory mutation system (PCR-ARMS). Results: The CRP, RF, ESR and TNF-α were significantly elevated in RA patients relative to controls. The serum level TNF-α was also significantly elevated in female patients and in patients ≥50 years. Analysis of TNF-308 gene polymorphism revealed that GG genotypes were more prevalent in RA patients than in the healthy individuals and that GG genotype may be a potential factor to RA. The G allele was more common in RA than in the control. Elevated TNF-α serum levels were significantly associated the GG genotype and functional disability in RA patients. Conclusion: TNF-α promoter 308polymorphism GG genotype may be considered as a risk factor for RA and the TNF-α serum level was significantly related to the functional disability in the disease.

Rheumatoid arthritis (RA) is a systemic inflammatory disease with chronic nature of joints related to autoimmunity. Vitamin D was found to modulate cell growth, function of immune cells and anti-inflammatory action. The aims of that study were to investigate serum level of vitamin D and some cytokines and to identify the correlation between vitamin D and these cytokines in RA. Totally 40 RA patients without vitamin D supplement were involved in this study. Serum level of vitamin D, interleukin-6 (IL-6), IL-10, IL-35, C-reactive protein (CRP) and tumor necrosis factor α (TNF-α), all of them were measure in all patients by enzyme-linked immunosorbent assay (ELISA). Patients were classified according to Vitamin D levels into two groups; RA patients with Vit. D deficiency (n=25) and RA patients with Vit. D sufficiency (n=15). IL-6 was lower significantly (P = 0.03) in RA patients with Vit. D sufficiency than RA patients with Vit. D deficiency. IL-10 and IL-35 were higher significantly (P = 0.0234, P = 0.0356 respectively) in RA patients with Vit. D sufficiency than RA patients with Vit. D deficiency. Vit. D was significantly positively correlated with both IL-10 (r = 0.4516, P = 0.0034) and IL-35 (r = 0.3424, P = 0.0329) and negatively correlated with IL-6 (r = -0.3188, P = 0.0479). Sufficient serum level of Vit. D is correlated with higher level of anti-inflammatory cytokines (IL-10 and IL-35) and lower level of IL-6. This support the immunomodulatory effect of Vit. D in RA.

IntroductionRheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease of unknown etiology which causes progressive deterioration of the joints, leading to severe pain and functional disability. Vitamin D and its receptor (VDR) play a significant part in the onset of autoimmune diseases such as RA. The purpose of this study was to evaluate the association between VDR gene polymorphisms and risk of developing RA.Material and methodsA retrospective study was performed, including 214 RA cases and 748 controls of Caucasian origin. FokI (rs2228570), BsmI (rs1544410), TaqI (rs731236), ApaI (rs7975232) and Cdx2 (rs11568820) gene polymorphisms were analyzed by TaqManResultsThe recessive logistic regression model showed that the VDR FokIAA genotype was associated with lower risk of RA (p = 0.0255; OR = 0.58; 95% CI: 0.35–0.92). No other genetic polymorphism showed any association with RA in any of the models tested. Haplotype analysis revealed that the haplotypes ACGAG (p = 0.033; OR = 1.62; 95% CI: 1.04–2.53) and GTGCA (p < 0.01; OR = 2.77; 95% CI: 1.53–4.98) for BsmI, Cdx2, FokI, ApaI and TaqI were associated with higher risk of RA.ConclusionsVDR FokI gene polymorphism showed a trend for risk of RA, taking into account the variables of gender, age and tobacco use, and preventing false positives. Among our patients we found no influence of VDR BsmI, TaqI, ApaI and Cdx2 on the risk of developing RA. However, haplotype analysis indicated that the haplotypes ACGAG and GTGCA were associated with higher risk of RA.

Objectives: The objectives of the study were to evaluate changes in 25(OH) Vitamin D levels and some biochemical parameters in rheumatoid arthritis (RA) patients compared with healthy controls and assess the correlation of 25-hydroxy Vitamin D, calcium, magnesium, and disease activity. Study the effects of anti-RA drugs on these biochemical parameters and also the role of supplements calcium and 25-OH Vitamin D in RA patients. Methods: This study conducted between 60 patients for RA and 20 healthy controls according to the American College of Rheumatology standards in 2010. In this study, 25-hydroxy Vitamin D was measured using an enzyme-linked immunosorbent assay, and also some biochemical parameters were measured with a spectrophotometer (Humalyzer 2000). Results: Serum 25(OH) Vitamin D, calcium, magnesium, and albumin levels were significantly lower in RA patients compared with healthy controls. Serum alanine aminotransferase aspartate aminotransferase levels were significantly increased in RA patients compared with healthy controls. The correlation was non-significantly among 25-hydroxy Vitamin D and clinical disease activity index (CDAI), while the results showed significantly inverse correlation calcium and magnesium concentrations with CDAI. Conclusion: 25-OH Vitamin D, calcium, albumin, and magnesium deficiency appear to be widespread in patients with RA. Thus, biochemical changes in RA are reflected in the pathogenesis of RA. Furthermore, in these results, there is no relationship between Vitamin D and the disease activity, while there is a relationship between calcium and magnesium with disease activity.

25 Hydroxy Vitamin D

Background. Besides the extensive regulatory role in growing number of biologic processes, vitamin D has been recently considered essential for lungs function as well as protective against exacerbation of chronic obstructive pulmonary diseases. We assessed the correlation between vitamin D serum levels with pulmonary function in healthy individuals. Methods. In a cross-sectional study, healthy volunteer (n=92) participants underwent the following laboratory procedures: a blood test, a 24-hour urine collection test, and the serum level of 25-hydroxy vitamin D before undergoing spirometry. Linear correlation coefficient was calculated to detect the association between serum level of 25-hydroxy vitamin D and pulmonary volumes. Results. The mean age of participants was 39.95±9.98 years. 48% of participants showed different levels of 25-hydroxy vitamin D deficiency. We recognized a consistent direct positive correlation between serum levels of 25-hydroxy vitamin D and lung function volumes. The coefficient for forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25–75%, and forced expiratory volume in 1 second/forced vital capacity ratio were 0.610, 0.509, 0.454, and 0.551, respectively. Conclusions. Our findings suggest correlation between higher serum levels of 25-hydroxy vitamin D and improved pulmonary function. Accordingly, supplemental vitamin D might significantly improve treatment response.
