The aim of this study was to assess the frequency of organ- and nonorgan-specific autoantibodies in MS patients and evaluate whether the presence of autoantibodies is an indicator of disease activity and/or a prognosis factor. One hundred and five definite MS patients in different stages and with different course and 75 blood donors were tested for the autoantibodies TgA, TMA/TPO-A, PCA, ANA, aCl, SMA, AMA and ANCA. All patients were screened for the LAC. Autoantibodies to at least one autoantigen were found in 66.6% MS patients and in 13.3% controls (P < 0.001). The frequency of TgA, TMA/TPO-A, ANA, aCl and SMA was statistically higher in patients than in controls. Circulating ANCAs were found in seven MS, a never reported finding. An early onset of MS (< 20 years) was associated with a lower autoantibody frequency (P < 0.01) Primary and secondary progressive MS had a higher antibody frequency than relapsing-remitting (P < 0.05) or benign (P < 0.001) MS. Up to 86% of patients were autoantibody-positive during the acute stage, but only 30% of them remained positive during the remission stage (P < 0.001). A generalised immune dysregulation occurs in MS patients, mostly during the acute stages and in the progressive courses, involving activation of both autoreactive Th1-cells (mainly linked to CNS lesions) and B-cells via Th2 cells.

Objective: To assess the risk of adverse pregnancy outcomes in patients with acquired and/or congenital thrombophilia factors. Patients and Methods: A cohort of 130 women with a history of pregnancy loss and no successful gestation were investigated for the presence of congenital and acquired thrombophilia factors, and then compared with a control group of 130 healthy women who had had at least one successful gestation and no pregnancy loss, and were screened for congenital and acquired thrombophilia factors. Results: Acquired and congenital thrombophilia factors were found in 30 (23%) patients and in 14 (10.8%) controls (p < 0.015). The presence of ≥1 congenital thrombophilia factor was associated with pregnancy loss with an odds ratio of 2.46 (p = 0.040). Moreover, women who had had >1 early fetal loss had a 2.85-fold risk of being carriers of congenital thrombophilia factors, compared to the controls. Conclusion: Our study showed the increased risk of miscarriage in patients with congenital thrombophilia factors and >1 early fetal loss. © 2014 S. Karger AG, Basel
