Haploidentical hematopoietic stem cell transplantation in children and adolescents with acquired severe aplastic anemia
Ho Joon Im, Kyung-Nam Koh, Jong Jin Seo
Clin Exp Pediatr. 2015;58(6):199-205.   Published online June 22, 2015

Severe aplastic anemia (SAA) is a life-threatening disorder for which allogeneic hematopoietic stem cell transplantation (HSCT) is the current available curative treatment. HSCT from matched sibling donors (MSDs) is the preferred therapy for children with acquired SAA. For patients who lack MSDs, immunosuppressive therapy (IST) is widely accepted as a first-line treatment before considering HCT from an unrelated donor (URD)....

Immune reconstitution after allogeneic hematopoietic stem cell transplantation in children: a single institution study of 59 patients
Hyun O Kim, Hyun Jin Oh, Jae Wook Lee, Pil-Sang Jang, Nack-Gyun Chung, Bin Cho, Hack-Ki Kim
Clin Exp Pediatr. 2013;56(1):26-31.   Published online January 29, 2013
Purpose

Lymphocyte subset recovery is an important factor that determines the success of hematopoietic stem cell transplantation (HSCT). Temporal differences in the recovery of lymphocyte subsets and the factors influencing this recovery are important variables that affect a patient's post-transplant immune reconstitution, and therefore require investigation.

Methods

The time taken to achieve lymphocyte subset recovery and the factors influencing this recovery were investigated...

Hematopoietic stem cell transplantation : overview for general pediatrician
Tai Ju Hwang
Clin Exp Pediatr. 2007;50(7):613-621.   Published online July 15, 2007
Hematopoietic stem cell transplantation (HSCT) has expanded and evolved substantially in the last decades to treat various malignant and nonmalignant diseases. However, the conditioning regimen can lead to transplantation related death by major organ dysfunction, severe infection and bleeding. In the allogeneic setting, graft versus host disease may also develop, making post-transplant management complex. To overcome these problems, new stem...
Aplastic anemia
Hack Ki Kim
Clin Exp Pediatr. 2007;50(6):519-523.   Published online June 15, 2007
Aplastic anemia is a rare disease, which is characterized by pancytopenia and hypocellular bone marrow without infiltration of abnormal cells or fibrosis. The incidence in Asia is higher than in the West and new cases are diagnosed at a rate of 5.1 per million pediatric populations per year in Korea. The pathophysiology is understood roughly by defective hematopoiesis, impaired bone...

Second allogeneic hematopoietic stem cell transplantation in children to overcome graft failure or relapse after initial transplant
Dong-Yeon Kim, Do Kyun Kim, Soo Young Kim, Seok Joo Kim, Dong Gyun Han, Hee Jo Baek, Hoon Kook, Tai-Ju Hwang
Clin Exp Pediatr. 2006;49(12):1329-1339.   Published online December 15, 2006
Purpose : Failure of hematopoietic stem cell transplantation(HSCT) may be encountered in practice because of either relapse of the malignancy or dysfunction of the graft. Second HSCT may be the only option for some patients whose initial HSCT failed. Methods : From May, 1991 to December, 2004, 115 HSCTs were performed at the Pediatric Blood & Marrow Transplantation Center, Chonnam National...

Clin Exp Pediatr. 2002;45(3):370-375.   Published online March 15, 2002
Purpose : In most cases, myelodysplastic syndrome(MDS) transforms into a more aggressive state or acute myelogenous leukemia; it's prognosis is very poor. It is believed that hematopoietic stem cell transplantation(HSCT) is the only curative treatment of MDS, but available data in children are very sparse. In this report, the short term outcome of HSCT in childhood MDS was analyzed. Methods :...
