Abstract

Forty-one patients with rheumatoid arthritis, including 6 with acute vasculitis, 13 with chronic vasculitis, and 22 without vasculitis, were studied for evidence of intravascular coagulation and fibrinolysis (ICF). The mean plasma fibrinogen levels were elevated in all groups. The fibrinogen, platelet count, and fibrin split products were usually elevated in acute vasculitis. Fewer patients on corticosteroids had abnormal coagulation tests. Active plasmin was detected in 12 patients primarily with chronic vasculitis. Plasminogen activator activity was not diminished in vascular endothelium of normal appearing skin of those patients with or without vasculitis. None of the patients demonstrated decompensated intravascular coagulation and fibrinolysis. The results suggest overcompensated ICF occurring in rheumatoid arthritis, but rheumatoid patients with vasculitis cannot be clearly distinguished from those without vasculitis on the basis of the usual tests performed for coagulation and fibrinolysis abnormalities.

Rituximab for treatment of opsoclonus-myoclonus syndrome in neuroblastoma.

Opsoclonus-myoclonus syndrome (OMS) is a rare paraneoplastic syndrome that occurs in 2%-3% of patients with neuroblastoma. The cause of this syndrome is believed to be immune mediated, but the exact mechanism still remains unclear. There is an urgent need to improve our current strategies for treating patients with OMS, as many patients have significant long-term neurologic deficits and behavior disorders with current treatment approaches. Therapies that have shown to improve symptoms in these patients have ranged from ACTH and corticosteroids, to intravenous gammaglobulin and plasmapheresis. We report our experience with Rituximab in a patient with neuroblastoma and OMS.

Cyclosporine sparing with mycophenolate mofetil, daclizumab and corticosteroids in renal allograft recipients: the CAESAR Study.

Although the calcineurin inhibitors (CNI) cyclosporine (CsA) and tacrolimus are highly effective immunosuppressants, they are associated with serious side effects. There is great interest in immunosuppressive regimens that permit reduction or elimination of CNIs, while maintaining adequate immunosuppression and acceptable acute rejection rates. Patients (n = 536) receiving their first renal allograft were randomized to one of three immunosuppressant regimens: daclizumab, mycophenolate mofetil (MMF), corticosteroids (CS) and low-dose CsA (target trough levels of 50-100 ng/mL), weaned from month 4 and withdrawn by month 6; daclizumab, MMF, CS and low-dose CsA; or MMF, CS and standard-dose CsA. Mean GFR 12 months after transplantation (primary end point) was not statistically different in the CsA withdrawal and low-dose CsA groups (both 50.9 mL/min/1.73 m(2)) vs. the standard-dose CsA group (48.6 mL/min/1.73 m(2)). At 12 months, the incidence of biopsy-proven acute rejection was significantly higher in the CsA withdrawal group (38%) vs. the low- or standard-dose CsA groups (25.4% and 27.5%, respectively; p < 0.05). In summary, a regimen of continuous low-dose CsA with MMF, CS and daclizumab induction is a clinically safe and effective immunosuppressive regimen in renal transplant recipients.
