Abstract EN
The effect of homocysteine on cardiovascular diseases is still equivocal, especially in rheumatoid arthritis patients.
In this investigation, the association between homocysteine with blood flow and vascular resistance in rheumatoid arthritis was examined.
Serum levels of homocysteine were determined in thirty-one rheumatoid arthritis patients and nineteen apparently healthy subjects using ELISA.
Additionally, strain-gauge plethysmography was used to determine both forearm blood flow and vascular function at rest and after occlusion.
Forearm occlusion blood flow (patients: 21.9 ± 6.55 versus control: 25.5 ± 6.10ml/100mL/min) was lower (p < 0.05) while occlusion vascular resistance (patients: 4.77 ± 2.08 versus controls 3.05 ± 0.96U) was greater (p < 0.01) in rheumatoid arthritis than in the controls.
Level of serum homocysteine was similar (p = 0.803) in rheumatoid arthritis group and healthy group.
In addition, level of serum homocysteine was correlated with resting blood flow (r = −0.41; p < 0.02) and resting vascular resistance (r = 0.31, p < 0.05) in the patients group.
The study confirms altered vascular function in rheumatoid arthritis.
Uniquely, the results show that homocysteine was related to resting, but not postischemia, vascular measures.
These relationships indicate that homocysteine might impact the vasculature in rheumatoid arthritis.
