[Stem cell transplantation in Morocco: report of 87 cases].

Purpose: The autologous peripheral blood stem cells (CSP) are used as a support to the restoration of the hematopoiesis in oncohematology. The objective of this work, carried out in the laboratory of cryobiology at the Center Regional of Blood Transfusion, Casablanca, is to assess the short- and long-term results of this type of autograft.

Patients And Methods: This retrospective study focused on 87 patients treated for hematological malignancies in services of oncohaematology over a period from June 2004 to March 2009.

[Kidney transplantation in a patient with haemophilia A].

A 37-year-old patient with moderate haemophilia A and end-stage renal disease underwent kidney transplantation in the University Hospital Ibn Rochd of Casablanca (Morocco). He received factor VIII replacement therapy perioperatively and until the 21st day postoperation. So, the activity rates of Factor VIII was higher than or equal to 80 % in the day of intervention and two to three days later, then between 30 and 60 % until healing.

[Systemic lupus erythematosus and Epstein-Barr virus].

We determined the prevalence of antibodies to Epstein-Barr virus (EBV) in 44 patients with systemic lupus erythematosus (SLE) and 44 healthy blood donors matched for sex and age as controls. Of the cases, 39 were women; mean age was 33 years. Four cases (9%) and 5 controls (11%) were positive for IgM anti-viral capsid antigen (VCA) (P = 0.
