Article Abstract

Introduction: High levels of lipoprotein (a) [Lp (a)] have gained attention as a risk factor for venous thrombosis. Venous thrombosis during pregnancy in women without thrombophilic predisposition is attributed to pregnancy itself. Herein, we report a case of high Lp (a) levels manifesting as recurrent deep vein thrombosis (DVT) and cerebral venous sinus thrombosis (CVST) in different pregnancies.

Case Presentation: A 29-year-old Nepalese woman developed DVT during her first pregnancy. Examination revealed no thrombophilic predisposition. The thrombus resolved with oral anticoagulant medication, which was discontinued after 3 months. During the second pregnancy, prophylactic subcutaneous heparin injections were initiated to prevent venous embolism. Following several days of non-administration of heparin, she experienced left occipital pain, and magnetic resonance venogram showed left CVST. Oral anticoagulants were initiated, and her headache resolved within a few days. Additional blood tests showed abnormally high levels of Lp (a) at 113 mg/dL. Six months later, the CVST was partially recanalized.

Conclusion: If venous thrombosis develops during pregnancy in patients without thrombophilic predisposition, Lp (a) levels should be monitored, and long-term anticoagulant medication may be desirable in those with high Lp (a) levels to prevent recurrence of venous thrombosis.

We previously used a disease-specific B cell receptor (BCR) point mutation (IGLV3-21R110) for selective targeting of a high-risk subset of chronic lymphocytic leukemia (CLL) with chimeric antigen receptor (CAR) T cells. Since CLL is a disease of the elderly and a significant fraction of patients is not able to physically tolerate CAR T cell treatment, we explored bispecific antibodies as an alternative for precision targeting of this tumor mutation. Heterodimeric IgG1-based antibodies consisting of a fragment crystallizable region (Fc) attached to both an anti-IGLV3-21R110 Fab and an anti-CD3 (UCHT1) single chain variable fragment (R110-bsAb) selectively killed cell lines engineered to express high levels of the neoepitope as well as primary CLL cells using healthy donor and CLL patient-derived T cells as effectors.

NAD Metabolism Regulates Proliferation of Macrophages in Atherosclerosis.

Department of Medicine/Division of Cardiology, University of California Los Angeles. (S.S., C.R.S., L.F., M.P., C.P., Z.Z., J.J.M., R.C.D., D.S., A.J.L.).

Background: In genetic studies with the Hybrid Mouse Diversity Panel, we previously identified a chromosome 9 locus for atherosclerosis. We now identify NNMT (nicotinamide -methyltransferase), an enzyme that degrades nicotinamide, as the causal gene in the locus and show that the underlying mechanism involves salvage of nicotinamide to nicotinamide adenine dinucleotide (NAD).

Methods: Gain/loss of function studies in macrophages were performed to examine the role of NAD levels in macrophage proliferation and apoptosis in atherosclerosis.

Objective: This study investigated the relationship of maternal serum uric acid, cystatin C (CysC), and coagulation indices [international normalized ratio (INR) and fibrinogen (FIB)] during pregnancy with clinical features and prognosis of early-onset pre-eclampsia.

Methods: Patients with pre-eclampsia (n = 133) were retrospectively selected, with clinical features and maternal uric acid, CysC, INR, and FIB levels collected. The relationship between clinical features and maternal uric acid, CysC, INR, and FIB was analyzed by Pearson's and Spearman's analyses.
