Allogeneic hematopoietic stem cell transplantation in leukocyte adhesion deficiency type 1: a single center experience.

Leukocyte adhesion deficiency type 1 is a rare autosomal recessive immunodeficiency disorder. The severe phenotype is fatal unless hematopoietic stem cell transplantation (HSCT) is performed. A retrospective analysis was performed in 11 patients with leukocyte adhesion deficiency type 1 who underwent HSCT and monitoring over a period of 19 years at our institution.

Outcome of second allogenic stem cell transplantation in pediatric patients with non-malignant hematological and immune deficiency disorders.

Background: Second stem cell transplantation (SCT) is usually associated with high morbidity and mortality and the data on its outcome in pediatric patients with non-malignant disorders are scarce.

Patients And Methods: We present 30 children with non-malignant conditions who underwent second SCT at our institution for graft failure after the first SCT; 20 had a non-malignant hematological disorder and 10 had an immune deficiency disorder. Median age at the second SCT was 6.

Clinical characteristics and treatment outcome of pediatric patients with chronic myeloid leukemia.

As chronic myeloid leukemia is rare in children, most data on imatinib mesylate therapy is derived from adult studies. We retrospectively evaluated pediatric (<14 years) patients with Ph+ chronic myeloid leukemia treated with imatinib mesylate, from January 2003 through June 2008. Of the 12 chronic myeloid leukemia patients (2% of all leukemias) 11 were in chronic phase while one had myeloid blast crisis.

Clinical characteristics and outcome of children with biphenotypic acute leukemia.

Background: Knowledge concerning the clinical and biological presentation, as well as the outcome of treatment, of biphenotypic acute leukemia in children is limited.

Design And Methods: This retrospective review analyzes the clinical features and outcome of children with biphenotypic acute leukemia diagnosed and treated over an 8-year period. According to the EGIL scoring system 24 (3.

Improved outcome for children with acute lymphoblastic leukemia after risk-adjusted intensive therapy: a single-institution experience.

Background And Objective: Because of the need for more comprehensive information on the least toxic and most effective forms of therapy for children with acute lymphoblastic leukemia (ALL), we reviewed our experience in the treatment of children with ALL at King Faisal Specialist Hospital and Research Centre (KFSH&RC) and King Fahad National Center for Children's Cancer and Research (KFNCCC&R) over a period of 18 years with a focus on patient characteristics and outcome.

Methods: During the period of 1981 to 1998, records of children with ALL were retrospectively reviewed with respect to clinical presentation, laboratory findings, risk factors, stratification, therapy and outcome. The protocols used in treatment included 4 local protocols (KFSH 81, 84, 87 and 90), and subsequently, Children's Cancer Group (CCG) protocols, and these were grouped as Era 1 (1981-1992) and Era 2 (1993-1998).

Second stem cell transplantation in patients with Fanconi anemia using antithymocyte globulin alone for conditioning.

Despite the promising data on the outcome of allogeneic stem cell transplantation (SCT) in patients with Fanconi anemia (FA), a certain percentage of these patients still experience graft failure; some of these patients undergo second transplants, but the existing data on the outcome of the second SCT in FA patients are scarce, with no long-term follow-up provided in many of the publications addressing this issue. This is a review of our experience in 4 such patients who underwent second stem cell transplants using rabbit ATG only for conditioning. Three engrafted promptly and are alive and free of disease at 25, 23, and 21 months, respectively.

Dexamethasone-associated toxicity during induction chemotherapy for childhood acute lymphoblastic leukemia is augmented by concurrent use of daunomycin.

Background: The goals of the current study were to examine the incidence and severity of toxicity resulting from dexamethasone and prednisone during induction therapy for children with precursor B-cell acute lymphoblastic leukemia (ALL) and to determine whether the addition of daunomycin affected toxicity.

Methods: Medical records of patients with precursor B-cell ALL from January 1996 through June 2000 were reviewed retrospectively for toxicity during the 4-week induction phase and the 2 weeks after the induction phase.

Results: One hundred seventy-six patients age < 14 years were diagnosed with precursor B-cell ALL from January 1996 through June 2000.
