In patients with IPD who are detected to have hyperhomocysteinemia, the assessment of the cognitive performance, folic acid and vitamin B12 levels and the supplementation of folic acid and vitamin B12 to the treatment regimen might be appropriate.

Introduction:The aim of our study was to investigate the vascular endothelial growth factor levels in joint swelling-positive and joint swelling-negative rheumatoid arthritis patients and to then examine the relationship between conventional parameters such as the erythrocyte sedimentation rate and the levels of C-reactive protein, rheumatoid factor, and anti-cyclic citrullinated protein.Methods:Fifty-nine (52 women and seven men) rheumatoid arthritis patients and 25 (20 women and five men) healthy individuals volunteered for this study. The patient group was divided into two sub-groups based on whether or not they exhibited joint swelling.Results:The levels of vascular endothelial growth factor in the joint swelling-negative group were significantly different from those in the joint swelling-positive group, but they were not different from those in the control group (p=0.001 and p=0.72, respectively). We investigated the correlation between vascular endothelial growth factor and C-reactive protein levels (r=0.37, p=0.001). We also evaluated the diagnostic adequacy of vascular endothelial growth factor and created a ROC curve. The area under the curve was calculated to be 0.767.Conclusion:Vascular endothelial growth factor is an adequate diagnostic biomarker and can successfully be used to predict the occurrence of rheumatoid synovitis based on local inflammation.
