ABSTRACT
The aim of this study was to evaluate CD25+ and Lag3+ T regulatory subpopulations in patients with critical carotid artery stenosis (CAS) and Stanford-A acute aortic dissection (AAD). CD25+ and Lag3+ were measured in 36 patients affected by CAS and 24 patients with Stanford type A AAD. Based on neurological symptoms, patients affected by CAS were further divided in 25 asymptomatic (CAS-A) and 11 symptomatic (CAS-S) subjects. Twenty-five patients with traditional cardiovascular risk factors (RF), matched for age and sex, were used as control group. Interleukin (IL)-10, IL-6 and transforming growth factor-ß-levels were also measured. CD25+ T cells were significantly increased in CAS-S versus CAS-A (p > 0.05), AAD (p > 0.05) and RF (p > 0.05). Moreover, a significant increase in Lag3+ Tregs was observed in CAS e CAS-S versus AAD (p < 0.05) and RF (p < 0.05), whereas no significant difference was observed between CAS-S and CAS-A. IL-6 was higher in AAD compared to the other groups. Patients with neurological symptoms display a peculiar expansion of CD25+ T cells, strongly confirming a relationship between ischemic brain damage and this regulatory subpopulation, whereas Lag3+ Tregs early distinguish CAS from AAD and probably exert protective actions against aortic wall rupture throughout their anti-inflammatory functions.

INTRODUCTION: The aim of this study was to evaluate the prevalence of antiphospholipid antibodies (aPLs) in infertile women undergoing in vitro fertilization (IVF). METHOD OF STUDY: From January 2012 to December 2017, 520 consecutive clinical records of infertile women undergoing IVF were evaluated. Among them, 100 consecutive clinical records of patients with positive autoantibodies were selected. RESULTS: In 100/520 (19.23%) women, positive auto-antibodies were detected: 35/520 (6.73%) fulfilled classification criteria for a systemic disease. Positive aPLs were observed in 43 women (8.27%): 17/520 (3.27%) fulfilled diagnostic criteria for PAPS/APS, whereas patients with positive aPLs, who fulfilled diagnostic criteria for a systemic autoimmune disease other than APS were 18/520 (3.46%). LA and aCL were the main aPLs detected 53.49% and 44.19% respectively, whereas aB2GPI were found in 25.58%. CONCLUSIONS: we suggest that women with infertility may represent a subpopulation of patients with underhanded systemic autoimmune syndromes in which the main symptoms represented are obstetrical complications. We, therefore, recommend evaluating aPLs in all patients undergoing IVF with the aim of recognizing women at a higher risk of miscarriage or pregnancy morbidity.

Obstetric antiphospholipid antibody syndrome (APS), is well defined by classification criteria. It is well known that women with APS should receive prophylactic anticoagulation therapy with subcutaneous low weight heparin all throughout pregnancy and in the first 6 weeks postpartum. However, the optimal treatment for pregnant women having positive anti-phospholipid antibodies, but not fulfilling classification criteria for APS is still unclear. In this retrospective study we report pregnancy outcomes of 10 patients affected by recurrent miscarriages and positive anti-cardiolipin or aß2GP1 antibodies with titers ranging from 10 to 20 GPL/MPL demonstrated at least twice before pregnancy.

Skin manifestations are often associated with systemic autoimmune diseases (SAD). Some SAD, such as systemic lupus erythematosus, psoriatic arthritis and scleroderma display pathognomonic dermatological features, whereas other systemic diseases such as sarcoidosis, vasculitis and rheumatoid arthritis can present with non-specific skin manifestations that range from erythema nodosum to necrotic lesions. Here we report the case of a 25-year-old man with uveitis, polyarthrirtis, pulmonary involvement, nephrotic syndrome, cutaneous granuloma and pneumonia by E. coli.
