Besides, 99 samples were found tobe positive by nested-PCR with a positive rate of40.7%. 61 samples were found to be simultaneously pos-itive in test of CMV antigen and DNA, with a rate of25.1%.Conclusions: Infection of CMV is common in recipi-ents of LT. Simultaneous screening of anti-CMV-Ab, CMV-Ag and CMV-DNA after liver transplanta-tion is very important for early diagnosis of CMV in-fection.展开更多
Aim of Work: To investigate the value of the detection of antibodies against modified citrullinated vimentin antibodies (anti-MCV) in comparison with anti-CCP2-for the diagnosis of rheumatoid arthritis (RA).

Patients and Methods: The study Included Forty patients with Rheumatoid arthritis (RA). They under went assessment by the disease activity score (DAS-28), visual analogue scale (VAS) and health assessment questionnaire (HAQ). Thirty healthy subjects matched for age and sex served as a control group. Blood samples were obtained from patients and controls for erythrocyte sedimentation rate (ESR), C reactive protein (CRP), rheumatoid factor (RF). Anti-CCP2 and anti-MCV were determined using ELISA technique. Results: Estimated serum levels of anti-CCP2 and anti-MCV were significantly higher in patients compared to controls (p 0.001). There were no significant correlations between anti-MCV levels and age, dis- ease duration, duration of morning stiffness, number of swollen and tender joints, HAQ or ESR in patients with RA, while serum levels correlates significantly with DAS28, VAS and CRP (p 0.05). Anti-CCP2 correlates significantly with DAS28, VAS and CRP and ANA (p 0.05). Serum anti-MCV and anti-CCP2 were significantly correlated with each other (r = 0.483;p The receiver operating characteristic (ROC) curve was drawn and it showed that anti-MCV had diagnostic specificity, sensitivity of 93.3%, 75.5%, respectively, while anti-CCP2 specificity, sensitivity of 98.1%, 85%, respectively. Conclusion: Serum anti-MCV as well as the anti-CCP-2 assay perform comparably well in the diagnosis of RA. In the high-specificity range, however, the anti-CCP2 assay appears to be superior to the anti-MCV test.展开更多
