The objective of this study is to examine and evaluate whether serum 25(OH)D is associated with disease activity in patients with rheumatoid arthritis (RA). Our results suggested that serum 25(OH)D in RA groups has significant lower level (35.99±12.59 nmol/L) than that in the normal groups (54.35±8.20 nmol/L,P<0.05). Based on the DAS28, patients with RA were divided into four subgroups, and no differences were found in the four groups (P>0.05). The 25(OH)D levels in complete remission, low disease activity, middle disease activity, and high disease activity group were32.86±12.26,33.97±13.28,38.41±10.64, and38.94±13.35 nmol/L, respectively. Based on the serum 25(OH)D levels, patients with RA were divided into inadequate group and normal group, and there were no significant differences in baseline characteristics and disease activity in the two groups. Our results showed that serum 25(OH)D levels in the inadequate group are significantly lower than those in the normal group. However, no correlations were found between 25(OH)D levels and disease activity among 116 patients with RA. The present findings will help to understand the association between 25(OH)D and disease activity of RA.

Background: Among rheumatoid arthritis patients (RA), general disease activity is well regulated by diseasemodifying anti-rheumatic medications (DMARDS), but sometimes local inflammation still persists among a few joints. Adjuvant modern molecular interventions as Platelet Rich Plasma (PRP) with a suggested down regulating effect on inflammatory mediators has a proven effect in management of RA. We aim to evaluate the therapeutic effect of intra-articular PRP versus steroid in RA patients and their impact on inflammatory cytokines IL1B , TNF α, local joint inflammation, disease activity and quality of life (QL). Methods: Open labeled parallel randomized control clinical trial was carried out on 60 RA patients randomly divided into 2 groups, Group 1: included 30 patients received 3 intra-articular injections of PRP at monthly interval, Group 2: included 30 patients received single intra-articular injection of steroid. They were subjected to clinical, laboratory, serum IL1B and TNF α assessment at baseline and at 3, 6 months post injection. Results: Patients of both groups showed improvements in their scores of evaluating tools at 3months post injection and this improvement was persistent in the PRP group up to 6 months post injection while it was continued only for 3 months in the steroid group. Conclusions: PRP is a safe, effective and useful therapy in treating RA patients who had insufficient response and persistent pain and inflammation in just one or two joints through its down regulating effect on inflammatory cytokines IL1B, TNF α with subsequent improvement of local joint inflammation, disease activity and QL.

Background:Vitamin D deficiency is more prevalent in patients with systemic lupus eythematosus (SLE) as a result of sun avoidance.1The potential negative impact of vitamin D deficiency on SLE disease activity has been shown in a number of studies.2The expression of the interferon signature genes in SLE correlates positively with disease activity, and these genes are thought to mediate the clinical manifestations of the disease.3Objectives:The aim of this study was to establish whether a relationship exists between serum 25-hydroxyvitamin D level and the interferon signature gene expression in whole blood of SLE patients.Methods:Informed consent was obtained from 92 SLE patients who were over the age of 18 and who fulfilled the SLICC classification criteria for SLE. The patients were interviewed and blood samples were taken. SLE disease activity was measured by SLE disease activity index-2K (SLEDAI-2K). RNA extraction was performed from whole blood. QuantiGene Plex technology was used to measure the expression of 12 interferon signature genes in the extracted RNA. The study was approved by the University Research Ethics Committee.Results:92.4% of the cohort studied were female. 58.7% were receiving vitamin D3 supplementation at a mean dose of 1031IU daily. 27.2% had vitamin D insufficiency (25-hydroxyvitamin D 21-29ng/ml) and 15.2% were vitamin D deficient (25-hydroxyvitamin D <20ng/ml). Mean serum 25-hydroxyvitamin D was 30.75ng/ml (standard deviation 9.53 ng/ml). Median SLEDAI-2K was 4 (range 0-12). Serum 25-hydroxyvitamin D had a significant negative correlation with body mass index (BMI) (R=-0.258, p=0.006) but there was no significant negative correlation with SLEDAI-2K or with the expression of the interferon signature genes. The expression of most interferon signatures genes measured (IFI35, OAS1, MX1, IFITM1, STAT2, IFIT3, IFIT1, STAT1, SOCS1) had a significant positive correlation with SLEDAI-2K.Conclusion:This study did not show a significant relationship between serum vitamin D level and disease activity. In keeping with this, there was no significant negative correlation between serum 25-hydroxyvitamin D and interferon signature gene expression. Further prospective studies and randomised controlled trials are required to study this relationship in greater depth.References:[1]Kamen DL, Cooper GS, Bouali H, Shaftman SR, Hollis BW, Gilkeson GS.

Background:The association between hyperuricemia and psoriatic arthritis (PsA) is actually generally accepted. Previous studies have demonstrated that uric acid suppress 25(OH)D metabolism [1]. More evidence is required to demonstrate the immune modulatory effects in psoriasis, psoriatic arthritis and other autoimmune diseases. In particular, the potential association between 25-hydroxyvitamin D serum levels and PsA still remains unknown.Objectives:To assess a clinical association between uric acid/25(OH)D serum levels ratio related to PASI, BASDAI and DAPSA, if any, in patients with psoriatic arthritis.Methods:We retrospectively observed 61 patients with psoriatic arthritis referred to our outpatients clinic, independently from already being on therapy or naïve. All selected patients underwent only conventional non-biological therapy at baseline and none received vitamin D supplementation and either allopurinol or febuxostat previously. Blood samples were drawn from all participants for assessment of 25-hydroxyvitamin D and uric acid serum levels. Disease activity of psoriasis and psoriatic arthritis were assessed by the Psoriasis Area and Severity Index (PASI), the Disease Activity Index for Psoriatic Arthritis (DAPSA) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). We assessed the covariates of interest by the Wilcoxon non parametric test, through the SPSS 24 Software.Results:We observed 61 patients, mainly females (83.6%). At the univariate analysis, the uric acid/25(OH)D serum levels ratio revealed significantly associated with DAPSA and BASDAI indexes (p<0.001 and p<0.001, respectively), whilst no significant association emerged with the PASI index (p=0.462).Conclusion:Data in the literature about these associations in the context of psoriatic arthritis are really poor. As a consequence, our findings, though preliminary, suggest us to hypothesize a potential role of uric acid/25(OH)D serum levels ratio as potential inflammation marker in order to better assess the disease activity. However, future larger studies are needed to investigate more in depth this association.[1]Charoenngam N, Ponvilawan B, Ungprasert P.
