Multiple cycles of rituximab therapy in chronic refractory immune thrombocytopenia: a case report with a 10-year follow-up.

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by isolated low platelet counts often leading to mucocutaneous bleeding. Administration of rituximab was shown to increase platelet counts in patients relapsing chronic ITP. However, duration of response with rituximab and the long-term benefit remains unknown.

Neonatal alloimmune thrombocytopenia due to anti-HPA-2b (anti-Koa).

Most severe cases of neonatal alloimmune thrombocytopenia (NAIT) are due to anti-HPA-1a (anti-PlA1) antibodies. We report a case of NAIT due to anti-HPA-2b that resulted in in utero intracranial hemorrhage.A 33-year-old G2P1A0 Caucasian woman had a routine ultrasound at 34 weeks.

Changes in immunological and virological parameters in HIV-1 infected subjects following leukapheresis.

In order to assess immune responses during HIV-1 therapeutic immunization, a large number of blood mononuclear cells (PBMC) are needed. Clinical tolerance and safety, as well as changes in immunological and virological parameters, were assessed, following leukapheresis in HIV-1 infected subjects with CD4(+) cell count >200 x 10(6)/l. PBMC were collected using a Fenwal CS3000 cell separator in 29 subjects with mean CD4(+) cell counts of 503 x 10(6)/l (range 172-1,119) and viral load of 2.

Reduction of donor exposures in premature infants by the use of designated adenine-saline preserved split red blood cell packs.

Objective: Critically ill neonates frequently require multiple small volume red blood cell (RBC) transfusions. RBC units assigned to individual infants, used sequentially in small aliquots until the original expiration date, can substantially reduce donor exposures. In 1993, adenine-saline solution (AS-3) was introduced by the Canadian Red Cross as the red cell storage medium to replace citrate-phosphate-dextrose-adenine anticoagulant-preservative solution (CPDA-1).
