    In the first part a prospective cohort study was reported to evaluate the efficacy and safety of a treatment protocol including plasma exchange (PE) or PE plus intravenous immunoglobulins (IVIG) or immunoadsorption (IA) plus IVIG administered in addition to conventional therapy to 22 pregnant women with high-risk APS. The results indicate that PE or IA treatments administered along with IVIG and conventional antithrombotic therapy could be a valuable and safe therapeutic option in pregnant APS women with triple antiphospholipid antibody positivity along with a history of thrombosis and/or one or more severe pregnancy complications. In the second part the efficacy and safety of PE combined with IVIG and steroids were evaluated for the treatment of 10 patients with autoimmune congenital heart block (CHB) by comparing maternal features, pregnancy outcome and side effects with those of 24 CHB patients treated with steroids only.

    Regulatory agencies encourage sponsors to submit 24-hour ambulatory ECG data for assessing cardiac safety of new drugs, and some arrhythmias, hitherto considered rare, have been observed in some early-phase studies. Interpretation of these observations is difficult given the dearth of published data on the prevalence of cardiac arrhythmias seen during 24-hour continuous ECG monitoring in healthy volunteers (HV) from clinical trials. We analyzed drug-free ambulatory ECG recordings from 1273 HV (1000 males, 273 females; age 18-65 years) from 22 phase 1 studies that were analyzed in a core ECG laboratory; all subjects had normal screening ECGs.

    Background: Chronic kidney disease (CKD) patients undergoing hemodialysis (HD) have a high risk of sudden cardiac death (SCD). A unique risk factor may be a longer interval between HD sessions (interdialytic period). Inherent in conventional HD (thrice-weekly) are two 48-hour short breaks (SIDP) and one 72-hour long break (LIDP) between HD sessions. Read More
