Abstract
BACKGROUND Serine/threonine kinase 4 (STK4) deficiency is a combined immunodeficiency (CID) characterized by early onset recurrent bacterial, viral, and fungal infections. Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative therapy for CID; however, little is known about the necessity and benefits of HSCT in patients with STK4 deficiency. METHODS We report two siblings with STK4 deficiency transplanted from two unrelated donors with the same conditioning regimen. RESULTS In the conditioning regimen, rituximab was given on Day -11 (375 mg/m2 ), and sirolimus was added on the same day. Busulfan was administered at a myeloablative dose (3.2 mg/kg; Days -7 to -4) with 150 mg/m2 of fludarabine (Days -7 to -3). They were transplanted with peripheral blood stem cells, and graft-versus-host disease (GVHD) prophylaxis was administered with 10 mg/m2 methotrexate on Days 1, 3, and 6. In addition, mycophenolate mofetil (MMF) was started on Day 1 with ongoing use of sirolimus. We did not encounter veno-occlusive disease (VOD), high-grade acute GVHD, or significant organ toxicity in either patient. Both patients were well at the end of the first year after HSCT with complete donor chimerism. CONCLUSIONS Serine/threonine kinase 4 deficiency is a disease with high mortality post-HSCT; therefore, the conditioning regimen and GVHD prophylaxis strategies are important considerations in these patients. In our opinion, the conditioning regimen, which includes rituximab and busulfan and fludarabine (BU-FLU), GVHD prophylaxis with sirolimus and MMF, and short-term methotrexate, offers favorable outcomes and is well tolerated in our STK4-deficient patients.

Abstract
BACKGROUND Although there are many studies on the role of vitamin D deficiency (VDD) in hematopoetic stem cell transplantation (HSCT), outcomes have often reported conflicting results because of the heterogeneity of the patients in the studies. METHODS We investigated the association between VDD prior to HSCT and outcomes after HSCT in a relatively homogenous group of patients with thalassemia major (TM) who received identical treatment for TM before transplantation, and the same conditioning regimen and GVHD prophylaxis during and after transplantation. All patients, including the patients with normal vitamin D3 levels received 400 to 800 IU per day of vitamin D for the first 6 months after HSCT. RESULTS Pre-HSCT VDD increased the frequency of aGVHD after transplantation, particularly in HSCTs performed with PBSC for the stem cell source. Pre-transplant low vitamin D3 levels had no association with transplant outcomes such as engraftment, viral infections, alloimmunization, chronic GvHD, total days of hospitalization, and success in terms of transfusion independence. CONCLUSIONS Low vitamin D3 levels before HSCT carry a significant risk for aGVHD. All patients with TM should be screened for VDD before HSCT, and every effort should be made to supplement vitamin D before the transplant in VDD patients.

Abstract
e22020 Background: The pediatric cancers is in the global agenda to improve the survival rates which is still low in LMICs although it is more than 80% in HICs. More than 300.000 pediatric cancer cases annually are expected in children and adolescents aged 0-14 globally. Registry is the first step of an efficient cancer control. Here, we present the most updated results of the pediatric cancer registry fromTurkey. Methods: Turkish Pediatric Oncology Group and Turkish Pediatric Hematology Association has established the pediatric cancer registry in 2002. The childhood cancer cases registered between 2009-2021 was included in this analysis. International Childhood Cancer Classification System was used for the classification. Essential demographic findings, ICD-O-3 morphology and topography codes were recorded for each case. Results: During the 13 years from 2009 to 2021, 24080 cases were registered. For all cases, median age was 6.7 year (0-19; M/F 13461/10609, 4 hermaphrodite, 6 unknown). Age distribution was 0-4 yrs, 40.8%; 5-9 yrs, 23.8%; 10-14 yrs, 23.3%; 15-19 yrs, 12.1%) The distribution of the tumor types were [number of cases, percentage of total, median age yrs, M/F]: Leukemia (5819, 24.2%, 5.5, 3366/2453); Lymphoma & other RES tumors (4446, 18.5%, 9.8, 2956/1487, 1 hermaphrodite & 2 unknown); CNS [brain & spinal] (3730, 15.5%, 6.8, 2061/1668, 1 unkown); Symphatetic system (1965, 8.2%, 2.3, 1010/955); Retinoblastoma (675, 2.8%, 1.4, 375/300); Renal (1160, 4.8%, 3.1, 557/601, 1 hermaphrodite & 1 unknown); Liver (409, 1.7%, 2.2, 234/175); Malignant bone (1584, 6.6%, 12.6, 864/720); Soft tissue sarcomas (1726, 7.2%, 7.7, 983/743); Germ cell (1593, 6.6%, 9.6, 588/1001, 2 hermaphrodite, 2 unknown); Carcinoma & other malignant epithelial (804, 3.3%, 13.5, 381/423); Other/non-specific malignant (169, 0.7%, 7.9, 86/83). Five year survival rate was found as 72.3%. Conclusions: The registry shows that the survival rates for children and adolescents have been improved to 72% which reflects the status of the pediatric cancer care in Turkey.

Abstract
BACKGROUND The use of unmanipulated haploidentical stem cell transplantations (haplo-HSCT) with post-transplant cyclophosphamide (PTCY) in children has emerged as an acceptable alternative to the patients without a matched donor. However, the timing of calcineurin inhibitors (CNI) used in combination with PTCY is increasingly becoming a topic of controversy. METHOD We evaluated 49 children with acute leukemia who underwent unmanipulated haplo-HSCT with PTCY according to the initiation day of CNIs (pre- or post-CY). RESULTS There were no significant differences in the overall survival analysis between the two groups. The cumulative incidence of relapse at 2 years was 21.2% in the pre-CY group and 38.9% in the post-CY group (p=0.33). Cytokine release syndrome (CRS) was observed more frequently in the post-CY group (p=0.04). The OS and EFS at 2 years in patients with and without CRS in the pre-Cy group were 42.9% vs 87.5% (p=0.04) and 38.1% vs 87.5% (p=0.04), respectively. CONCLUSION Our study shows that the argument for starting CNI administration after CY is tenuous, and the rationale for not starting CNI before CY needs to be reconsidered.

Abstract
EBV-associated lymphoproliferative disorders (LPDs) are common in hematopoietic stem cell transplantation (HSCT) with T-cell-depleted grafts, but are extremely rare in HSCT patients with T-cell-replete grafts with post-transplant cyclophosphamide (PTCy). Here we present the cases of two pediatric patients who developed EBV-related LPD after T-cell-replete haplo-HSCT with PTCy. One of these is the first reported case of EBV-positive mucocutaneous ulcer (EBVMCU) developing after PTCy. EBV-related diseases are rare in T-cell-replete haplo-HSCT patients with PTCy. However, in patients with risk factors, it is reasonable to screen for EBV viremia for LPD.

Abstract
Pearson syndrome (PS), shares a number of overlapping features with Diamond-Blackfan anemia (DBA), including early onset of severe anemia, making differential diagnosis important. Differential diagnosis of DBA and PS is critical, since those with DBA may respond to treatment with steroids, may undergo remission, or may benefit from hematopoietic stem cell transplantation (HSCT). However, patients with PS have a different prognosis, with a very high risk of developing acidosis, metabolic problems, and pancreatic dysfunction, and a shorter life expectancy than those with DBA. Here we present a patient who underwent HSCT for DBA but was subsequently diagnosed with PS after developing some complications.

Abstract
OBJECTIVES X-linked adrenoleukodystrophy (X-ALD), is a peroxisomal inborn error of metabolism caused due to the loss of function variants of ABCD1 gene that leads to accumulation of very long chain fatty acids (VLCFAs) in several tissues including the neurological system. Childhood cerebral X-ALD (CCALD) is the most common and severe form of X-ALD, if left untreated. Allogenic hematopoietic stem cell transplantation (HSCT) is the only available therapy that halts neurological deterioration in CCALD. We present 12 patients with several subtypes of X-ALD that were followed-up in a single center. METHODS Data of 12 patients diagnosed with X-ALD were documented retrospectively. Demographics, age of onset, initial symptoms, endocrine and neurological findings, VLCFA levels, neuroimaging data, molecular genetic analysis of ABCD1 gene, and disease progress were documented. RESULTS Mean age of initiation of symptoms was 7.9 years and mean age of diagnosis was 10.45 years. Eight patients had the CCALD subtype, while two had the cerebral form of AMN, one had the adult form of cerebral ALD, and one patient had the Addison only phenotype. The most common initial symptoms involved the neurological system. Loes scores varied between 0 and 12. Seven patients with CCALD underwent HSCT, among them three patients died. The overall mortality rate was 25%. CONCLUSIONS Patients with X-ALD should be carefully followed up for cerebral findings and progression, since there is no genotype-phenotype correlation, and the clinical course cannot be predicted by family history. HSCT is the only available treatment option for patients with neurological deterioration.

Abstract
BACKGROUND Post-transplant relapse has a dismal prognosis in children with acute leukemia undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Data on risk factors, treatment options, and outcomes are limited. PROCEDURE In this retrospective multicenter study in which a questionnaire was sent to all pediatric transplant centers reporting relapse after allo-HSCT for a cohort of 938 children with acute leukemia, we analyzed 255 children with relapse of acute leukemia after their first allo-HSCT. RESULTS The median interval from transplantation to relapse was 180 days, and the median follow-up from relapse to the last follow-up was 1844 days. The 3-year overall survival (OS) rate was 12.0%. The main cause of death was disease progression or subsequent relapse (82.6%). The majority of children received salvage treatment with curative intent without a second HSCT (67.8%), 22.0% of children underwent a second allo-HSCT, and 10.2% received palliative therapy. Isolated extramedullary relapse (hazard ratio (HR): 0.607, P = .011) and relapse earlier than 365 days post-transplantation (HR: 2.101, P < .001 for 0-180 days; HR: 1.522, P = .041 for 181-365 days) were found in multivariate analysis to be significant prognostic factors for outcome. The type of salvage therapy in chemosensitive relapse was identified as a significant prognostic factor for OS. CONCLUSION A salvage approach with curative intent may be considered for patients with post-transplant relapse, even if they relapse in the first year post-transplantation. For sustainable remission, a second allo-HSCT may be recommended for patients who achieve complete remission after reinduction treatment.

Abstract
e22519 Background: Global actions on pediatric cancer control is targeting to improve the survival rates in low and middle income countries which already exceeded 80% in high income countries. Almost 300.000 pediatric cancer cases annually are expected in children and adolescents aged 0-14 globally. Pediatric cancer registry must be a priority within the pediatric cancer control programs. Here, we present the most updated results of the pediatric cancer registry in Turkey. Methods: Pediatric cancer registry has been established by the Turkish Pediatric Oncology Group and Turkish Pediatric Hematology Association in 2002. The childhood cancer cases registered between 2009-2020 was included in this analysis. International Childhood Cancer Classification System was used for the classification.

Abstract
Although advancements have been made in monitoring and preventing viral infections in HSCT patients, CMV reactivation still remains a critical post-transplant complication. Adoptive cell therapy is an alternative to pharmacotherapy of CMV infection in refractory patients. We retrospectively reviewed CMV infection cases after allogeneic HSCT who received U-DLI as treatment. In total, five pediatric patients between the ages of 0.5-16 years that received U-DLI for a post-HSCT CMV infection were evaluated. The dose of CD3+ lymphocytes administered in DLI was 5 × 104 /kg, except in one patient transplanted from his sibling. One patient, who was transplanted from an unrelated donor, received U-DLI from his haploidentical mother. CMV titers dramatically reduced after U-DLI. If the availability of CMV-specific CTL is an issue, we propose that one should consider using the U-DLI therapy with low cell dose from a seropositive donor. In case the stem cell donor is seronegative and a seropositive donor is unavailable, using the U-DLI therapy from seropositive, haploidentical donors is a promising way of treatment. More studies need to be conducted to further confirm the safety and efficacy of this treatment procedure.

Abstract
Deficiency of the CD40L, expressed on the surface of T lymphocytes, is caused by mutations in the glycoprotein CD40L (CD154) gene. Resulting defective humoral and cellular responses cause a clinical presentation that includes recurrent sinopulmonary bacterial infections, opportunistic infections, sclerosing cholangitis, neutropenia, and autoimmune manifestations. HSCT represents the only curative treatment modality. However, the therapeutic decision to use HSCT proves challenging in many cases, mainly due to the lack of a phenotype-genotype correlation. We retrospectively reviewed patients with CD40L deficiency who were transplanted in Antalya and Göztepe MedicalPark Pediatric HSCT units from 2014 to 2019 and followed by Akdeniz University School of Medicine Department of Pediatric Immunology. The records of eight male cases, including one set of twins, were evaluated retrospectively. As two transplants each were performed on the twins, a total of ten transplants were evaluated. Conditioning regimens were predominantly based on myeloablative protocols, except for the twins, who received a non-myeloablative regimen for their first transplantation. Median neutrophil and platelet engraftment days were 13 (range 10-19) and 14 (range 10-42) days, respectively. In seven of ten transplants, a CMV reactivation was developed without morbidity. None of the patients developed GVHD, except for one mild case of acute GVHD. All patients survived, and the median follow-up was 852 days. Our data show that HSCT for patients with CD40 ligand deficiency is a potentially effective treatment for long-term disease control.

Abstract
e22513 Background: The pediatric cancer registry is an essential element of pediatric cancer control. More than 200000 pediatric cancer cases annually are expected in children and adolescents aged 0-14 globally. The current efforts are focusing to improve the survival rates for children and adolescents in LMICs since the survival has already exceeded 80% in most of the high income countries. Here we present the most updated results of the pediatric cancer registry in Turkey. Methods: Pediatric cancer registry has been established by theTurkish Pediatric Oncology Group and Turkish Pediatric Hematology Association in 2002. The childhood cancer cases registered between 2009-2019 was included in this analysis. International Childhood Cancer Classification System was used for the classification. Essential demographic findings, ICD-O-3 morphology and topography codes were recorded for each case. Results: During the 11 years from 2009 to 2019, 17770 cases were registered. For all cases, median age was 6.8 year (0-17; M/F 9973/7789, 3 hermaphrodite, 5 unknown). Age distribution was 0-4 yrs, 40.3%; 5-9 yrs, 24.0%; 10-14 yrs, 23.6%; 15-19 yrs, 12.1%) The distribution of the tumor types were [number of cases, percentage of total, median age yrs, M/F]: Leukemia (4570, 25.7%, 5.5, 2633/1937); Lymphoma & other RES tumors (3477, 19.6%, 9.9, 2324/1150, 1 hermaphrodite & 2 unknown); CNS [brain & spinal] (2493, 14.0%, 6.9, 1363/1129, 1 unkown); Symphatetic system (1426, 8.0%, 2.4, 743/683); Retinoblastoma (348, 2.0%, 1.5, 204/144); Renal (905, 5.1%, 3.2, 435/469, 1 unknown); Liver (304, 1.7%, 1.8, 172/132); Malignant bone (1209, 6.8%, 12.6, 658/551); Soft tissue sarcomas (1221, 6.9%, 7.5, 703/518); Germ cell (1165, 6.6%, 8.8, 426/736, 2 hermaphrodite, 1 unknown); Carcinoma & other malignant epithelial (533, 3.0%, 13.8, 254/279); Other/non-specific malignant (119, 0.7%, 8.5, 58/61). Five year survival rate was found as 71.9%. Conclusions: The data is the most essential part of the cancer control.This registry has been used widely among professionals since its establishment in 2002. Survival rates for children and adolescents has been improved to 70%. This is at the acceptable level for the income level of Turkey which is classified as an upper middle income country. The registry is a useful source for investigators and decision makers at national and international level.

Abstract
BACKGROUND Despite the increasing performance of allogeneic hematopoietic cell transplantation over the last decades, graft-versus-host disease (GVHD) remains the main cause of morbidity and mortality. The efficacy of ruxolitinib against GVHD has been demonstrated in adult studies; however, very few studies have been conducted in children. PROCEDURE This study aimed to evaluate the efficacy of ruxolitinib in 29 children with steroid-refractory acute or chronic GVHD. Twenty-five (87%) patients received at least three different immune modulator agents, including methylprednisolone, before initiating ruxolitinib. RESULTS All grade 2 acute GVHD patients completely responded to ruxolitinib treatment; 82% of high-grade (3-4) acute GVHD patients and 80% of chronic GVHD (moderate-severe) patients had at least a partial response. Of seven patients with bronchiolitis obliterans, five had a partial response after ruxolitinib. Of 29 patients, 22 were administered steroids at any time in the first month of acute GVHD or the first three months of chronic GVHD during ruxolitinib usage, which was significantly tapered by the end of the observation period. CONCLUSION Steroid-refractory acute and chronic pediatric GVHD patients treated with ruxolitinib had a high overall response rate, with the additional benefit of steroid sparing.

Abstract
We examined outcomes of 51 pediatric patients with relapsed acute leukemia (AL) who underwent a second allogeneic hematopoietic stem cell transplantation (alloHSCT). After a median follow-up of 941 days (range, 69-2842 days), leukemia-free survival (LFS) and overall survival (OS) at 3 years were 26.6% and 25.6%, respectively. The nonrelapse mortality rate (NMR) and cumulative incidence of relapse (CIR) were 36.4% and 42.4%, respectively. The Cox regression analysis demonstrated that the risk factors at second transplantation for predicting limited LFS were active disease (hazard ratio (HR) = 5.1), reduced intensity conditioning (RIC) (HR = 5.0), matched unrelated donor (MUD) (HR = 3.4) and performance score <80 (HR = 3.2). Pediatric patients with AL who relapsed after their first alloHSCT may survive with a second alloHSCT. Disease status, conditioning intensity, donor type, and performance score at the second transplantation are the relevant risk factors. A score based on these factors may predict the results of the second transplantation.

Abstract
BACKGROUND Post-Cy administration for GVHD prophylaxis in unmanipulated haploidentical HSCT has resulted in improved outcomes in recent years. Studies in children are lacking and accordingly we present the outcomes of 62 haploidentical transplantation for high-risk children. PROCEDURE We retrospectively assessed 62 transplants in 60 patients who underwent haploidentical-related HSCT with unmanipulated stem cells and for whom Post-Cy was used for GVHD prophylaxis. RESULTS Myeloid reconstitution was achieved on day + 30 for 57 of the 62 patients. The median follow-up of the surviving 39 patients (63%) was 26 months, with a range of 6-57 months. The OS and EFS at 2 years were 64.6% (52.0%-77.2%, 95% CI) and 58.9% (46.1%-71.7%, 95% CI), respectively. The only factor in our multivariate analysis that contributed to an inferior EFS was a poor remission status prior to HSCT (HR, 8.30; 1.08-63.56; P = 0.041, 95% CI). CONCLUSION The results of T-cell replete haploidentical transplantation with Post-Cy GVHD prophylaxis in high-risk pediatric patients are promising. However, further research is needed to determine the factors that have affect HLA compatibility for predicting the success of haploidentical transplantations.

Abstract
CNL is a rare myeloproliferative disorder frequently seen in older adults. A significant proportion of patients show progression to AML. Here, we report the case of a patient with FA who was monitored for leukopenia but who developed leukocytosis during the follow-up and was diagnosed with CNL probably after an acquired CSF3R mutation. Because the patient had FA, which could accelerate the progression to AML, an HSCT was performed, which resulted in cure. This patient (aged 12 years) is one of the youngest patients reported to develop CNL as well as the first FA patient with a diagnosis of CNL.

Abstract
DIDS is a unique form of combined immune deficiency characterized by an unusual susceptibility to cutaneous viral infections, severe allergies with eosinophilia and elevated immunoglobulin E titers, autoimmunity, and cancer. HSCT is considered the standard of care for this deadly disease. We have retrospectively analyzed the outcome of allogeneic HSCT from unrelated donors in patients with DIDS. Data from four patients, with five transplants, are presented. All patients received transplants from unrelated donors' BM, except for one patient who received a cord blood transplant. The conditioning regimens were based on myeloablative protocols for BM derived transplants; a NM regimen was pursued for the patient who received a cord blood transplant, which resulted in graft rejection. Although recurrent pneumonia and skin infections resolved immediately after transplantation, all patients subsequently developed human herpesvirus infection, including cutaneous herpetic lesions, cytomegalovirus reactivation, and zona zoster, which could be attributed to the use of ATG. Despite the presence of serious morbidities prior to transplantation, all patients recovered successfully. DIDS can be successfully treated with allogeneic HSCT from unrelated donors following a myeloablative conditioning regimen, with a reasonable safety profile.

Abstract
Objective: The Turkish Society of Pediatric Hematology set up a National Hemoglobinopathy Registry to demonstrate the demographic and disease characteristics of patients and assess the efficacy of a hemoglobinopathy control program (HCP) over 10 years in Turkey. Materials and Methods: A total of 2046 patients from 27 thalassemia centers were registered, of which 1988 were eligible for analysis. This cohort mainly comprised patients with β-thalassemia major (n=1658, 83.4%) and intermedia (n=215, 10.8%). Results: The majority of patients were from the coastal areas of Turkey. The high number of patients in Southeastern Anatolia was due to that area having the highest rates of consanguineous marriage and fertility. The most common 11 mutations represented 90% of all β-thalassemia alleles and 47% of those were IVS1-110(G->A) mutations. The probability of undergoing splenectomy within the first 10 years of life was 20%, a rate unchanged since the 1980s. Iron chelators were administered as monotherapy regimens in 95% of patients and deferasirox was prescribed in 81.3% of those cases. Deferasirox administration was the highest (93.6%) in patients aged <10 years. Of the thalassemia major patients, 5.8% had match-related hemopoietic stem cell transplantation with a success rate of 77%. Cardiac disease was detected as a major cause of death and did not show a decreasing trend in 5-year cohorts since 1999. Conclusion: While the HCP has been implemented since 2003, the affected births have shown a consistent decrease only after 2009, being at lowest 34 cases per year. This program failure resulted from a lack of premarital screening in the majority of cases. Additional problems were unawareness of the risk and misinformation of the at-risk couples. In addition, prenatal diagnosis was either not offered to or was not accepted by the at-risk families. This study indicated that a continuous effort is needed for optimizing the management of thalassemia and the development of strategies is essential for further achievements in the HCP in Turkey.

Abstract
We explored the clinical course of acute high-grade gastrointestinal graft-versus-host disease in children in a single center. This was a retrospective analysis of 28 pediatric patients who presented with a clinical diagnosis of stage III and IV acute graft-versus-host disease (aGVHD) of the gastrointestinal system (GIS). Generally, skin involvement was the initial manifestation of aGVHD that began in the first 3 weeks of hematopoietic stem cell transplantation (HSCT); on the other hand, GIS involvement predominated after the second week of HSCT. Reported adult data show a survival rate of only 25%; however, our study showed more favorable outcomes in children with a survival rate of 55%. We monitored levels of albumin and immunoglobulin G and observed low levels overall during treatment of unresponsive patients, although only albumin levels were shown to be significantly different. We observed a significant increase in mortality with the use of antithymocyte globulin in GIS aGVHD, although antithymocyte globulin used for graft-versus-host disease prophylaxis had no demonstrable effect on GIS aGVHD mortality. Whether the significantly lower GIS aGVHD mortality among the children recruited in our study than among their historical adult counterparts is a primary result of the specific attributes of the pediatric GIS, or whether it originated from HSCT kinetics remains to be determined by future studies.

Abstract
Hematopoietic cell transplantation is an established treatment option with curative potential for a variety of clinical conditions. The last decade especially witnessed a remarkable increase in HCT activity in Turkey. In 2014, 696 pediatric and 2631 adult (total 3327) HCT were performed in Turkey. Corresponding transplant rates per 10 million inhabitants for autologous-HCT and allogeneic-HCT were 226 and 202, respectively. Total HCT procedures in Turkey increased 177% in the last 5 years and 791% in the last 14 years. This report focuses mainly on HCT activity of Turkey in 2014 based on the national HCT registry and presents a general picture of national HCT activity.

Abstract
IHA is characterized by a sudden increase in plasma ammonia levels in the absence of any identifiable causes, which mostly results in intractable coma and high mortality. It has been reported in some patients after receiving intensive chemotherapy for hematological malignancy or HSCT. We describe a case of a patient with FA that developed acute idiopathic hyperammonemia after the preparative regimen for HSCT.

Abstract
Extracorporeal photopheresis (ECP) has been used widely in the treatment of steroid-refractory chronic graft versus host disease (cGVHD). Several reports have applied an 'early treatment' approach due to the better response rates compared with late treatment. However, herein, we report a hematopoetic stem cell transplantation performed in a thalassemia major patient presenting with severe cGVHD who applied to our center for ECP treatment nearly 12 years after the onset of cGVHD.

Abstract
AIMS AND OBJECTIVES The aims of this study were to: (1) determine the types of complementary and alternative medicine use among children with thalassaemia as reported by parents and (2) describe sociodemographic and medical factors associated with the use of such treatments in families residing in southern Turkey. BACKGROUND Thalassaemia is one of the most common human genetic diseases. Despite the therapeutic efforts, patients will encounter a variety of physical and psychological problems. Therefore, the use of complementary and alternative medicines among children thalassaemia is becoming increasingly popular. DESIGN This is a descriptive study of complementary and alternative medicine. METHODS This study was conducted in the Hematology Outpatient Clinic at Akdeniz University Hospital and in the Thalassemia Centre at Ministry of Health Antalya Education and Research Hospital, Antalya, Turkey, between January 2010-December 2010. Parents of 97 paediatric patients, among 125 parents who applied to the haematology outpatient clinic and thalassaemia centre between these dates, agreed to take part in the study with whom contact could be made were included. Data were collected by using a questionnaire. RESULTS The proportion of parents who reported using one or more of the complementary and alternative medicine methods was 82·5%. Of these parents, 61·8% were using prayer/spiritual practice, 47·4% were using nutritional supplements and 35·1% were using animal materials. CONCLUSION It was determined that a significant portion of the parents using complementary and alternative medicine use it to treat their children's health problems, they were informed about complementary and alternative medicine by their paediatricians and family elders, and they have discussed the use of complementary and alternative medicine with healthcare professionals. RELEVANCE TO CLINICAL PRACTICE To sustain medical treatment and prognosis of thalassaemia, it is important for nurses to consult with their patients and parents regarding the use and potential risks of some complementary and alternative medicine.

Abstract
Although successful hematopoietic stem cell transplantation (HSCT) can offer a cure in thalassemia major, there are only a few and noncomprehensive studies of its effect on the quality of life (QoL), as it is expected to increase the QoL by ending transfusion-related issues. Our objective was to compare the health-related quality of life (HRQoL) of transplanted and nontransplanted thalassemia major patients in a developing country. We have studied the QoL effect of HSCT in consecutively invited 50 nontransplanted and 49 transplanted patients who had received transplants from HLA matched related donors at least two years ago. PedsQL questionnaire was used for the patients under 18 years of age and World Health Organization's WHOQoL-BREF questionnaire for above 18 years of age. Higher QoL was determined in HSCT performed group surveyed in 5-18 years' age group. Detailed analysis marked the profound difference in 8-12 year subgroup, particularly in physical activity questionnaires. QoL scores in HSCT performed adult group are higher than the transfusion-dependent group, especially in physical activity domain. Transplanted adult patients rated their overall health significantly better than patients on conventional therapy. The patients who still have chronic graft versus host disease rated worse compared to those without it. In conclusion, thalassemia major patients who have undergone HSCT at least two years before assessment are not inferior to the transfusion-dependent group with regard to the QoL and have a better QoL than transfusion-dependent patients in some areas. The QoL score is better for school children and adolescents; therefore, we suggest HSCT before primary school. GVHD reduces the QoL significantly and it is obvious that GVHD prevention should be one of the primary goals of post-HSCT follow-up.

Abstract
Objective: The aim of this study was to document hematopoietic stem cell transplantation (HSCT) activity and trends at our treatment center. Material and Methods: Data collected over a 10-year period were retrospectively analyzed, concentrating primarily on types of HSCT, transplant-related mortality (TRM), stem cell sources, indications for HSCT, and causes of death following HSCT. Results: In total, 222 allogeneic (allo)-HSCT (87.4%) and 32 autologous (auto)-HSCT (12.6%) procedures were performed between 1998 and 2008. Stem cells obtained from unrelated donors were used in 22.6% (50/222) of the allo- HSCTs. Cord blood was the source of hematopoietic stem cells (HSC) in 12.2% of all transplants. The most common indication for allo-HSCT was hemoglobinopathy (43.2%), versus neuroblastoma (53.1%) for auto-HSCT. The TRM rate 1 year post transplantation was 18.3% ± 2.5% for all transplants, but differed according to transplantation type (23.5% ± 7.9% for auto-HSCT and 17.5% ± 2.6% for allo-HSCT). The most common cause of death 1 year post HSCT was infection (35.9%). Conclusion: The TRM rate in the patients that underwent allo-HSCT was similar to that which has been previously reported; however, the TRM rate in the patients that underwent auto-HSCT was higher than previously reported in developed countries. The selection of these patients to be transplanted must be made attentively.

Abstract
One hundred and one children with visceral leishmaniasis (VL) who admitted to Akdeniz University Hospital during a 20-year period were analyzed. Median age of the patients was 3 years (range: 5.5 months-13 years). The most common symptoms at presentation were fever, pallor and abdominal distension. Splenomegaly was found in all of the patients while hepatomegaly was present in 98%. Anemia (96%), leukopenia (74%) and thrombocytopenia (56%) were the main laboratory abnormalities. Thirty-three (33%) of the patients were pancytopenic on admission. Bone marrow smear was positive for leishmania in 91% of the patients. Seventy-four patients were treated with antimony +/- pentamidine and 27 with amphotericin B. Three of our patients died because of secondary infections and hemorrhage. Relapse was observed in two patients. No patient showed post kala-azar dermal leishmaniasis findings. We conclude that VL should be considered in patients with prolonged fever, hepatosplenomegaly and cytopenia who live in an endemic region. Amphotericin B is a therapeutic agent as effective as pentavalent antimony compounds and could be preferred.

Abstract
Beta-thalassemia, which is an autosomal recessive disease, is among the most common hemoglobinopathies in Antalya, Turkey. Mutations found in Turkish beta-thalassemia patients constitute a heterogeneous group, which is mostly composed of point mutations and, only in very rare cases, a deletion or an insertion causes affected or carrier phenotypes. Reverse dot blot hybridization (RDBH) method is used for screening common mutations, and sequence analysis and silver staining were performed consecutively to detect any uncommon mutation. The authors report a first Turkish family with a rare variant--intervening sequence 2 (IVS2) 849 (A-G). The proband's mother and father were determined as carriers of IVS2.849 (A-G) and IVS1.1 (G-A) mutations, respectively. Proband is the first child of the family and she has an IVS2.849 (A-G)/IVS1.1 (G-A) genotype with ss-thalassemia major phenotype. Prenatal diagnosis was performed for the second child, and genotype of the fetus was determined as IVS2.849 (A-G)/Normal. This first report of IVS2.849 (A-G) mutation in Turkish population shows that there are many more mutations contributing the heterogeneity of the mutation spectrum of beta-globin gene in the Turkish population, which indicates migrations of different ethnic origins.

Abstract
Compound heterozygosity for Hb Tyne and HbS, that is very rare, was identified by direct DNA sequencing of the beta-globin gene in a Turkish patient. Hematological investigation of a girl at the age of 9 due to the presence of HbS (40.7%) led to the identification of a compound heterozygosity at codons 5-6. This was found to be the result of substitution of cytosine (C) for thymidine (T) at the fifth position and a substitution of adenine (A) for thymidine (T) at the sixth position of the beta globin gene. As a result of these mutations, the order of amino acids at codons 5-6 was changed from Pro-Glu to Ser-Val, respectively. Since the co-inheritance of Hb Tyne and HbS had not been reported in literature before, our case set an example for identification of coinheritance of Hb Tyne and HbS for the first time. Therefore, such cases may be considered as an important example for understanding the structural variants of hemoglobin and may provide important clues for critical amino acids responsible for stabilization of hemoglobin tetrameric structure and genetic counseling.

Abstract
Cytomegalovirus (CMV) disease remains an important cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). We evaluated high-dose acyclovir (HDACV) and pre-emptive ganciclovir to prevent CMV disease in 76 children who underwent peripheral blood stem cell transplantation (PBSCT) and were at risk for CMV reactivation and disease (both recipient and donor seropositive) from May 1998 to April 2003. All received HDACV from day -9 to 6 months post transplant in conjunction with weekly CMV pp65 antigenemia monitoring. The incidence of antigenemia in this cohort was 19.7%, at a median of 22 days post-PBSCT. The frequencies were 26.4 and 4.4% in allogeneic and autologous groups, respectively (P=0.03). Patients with nonmalignant disease had higher CMV antigenemia than those with malignant disease (30.8 vs 8.1%, P=0.02). Age at PBSCT, sex, graft-versus-host disease (GVHD) prophylaxis regimen and presence of acute GVHD did not affect the risk of CMV antigenemia. None of the patients who had positive pp65 antigenemia developed CMV disease during the study period. We conclude that pp65 antigenemia-guided HDACV and pre-emptive ganciclovir may prevent CMV disease in children undergoing PBSCT.

Abstract
We measured Thrombopoietin (Tpo) levels in thrombocytopenic term and preterm babies with infection to investigate the relationship between thrombopietin levels and platelet counts. Sixteen preterm (27-34 weeks' gestational age) and 5 term neonates (38-41 weeks' gestational age) with the diagnosis of neonatal infection and thrombocytopenia (platelets <150 x 10(9)/L) but, without the evidence of disseminated intravascular coagulation, were prospectively enrolled in the study. Fifteen preterm (27-34 weeks' gestational age) and 9 term (38-40 weeks' gestational age) age-matched healthy neonates were enrolled in the study as control. Blood samples were obtained from each subject at the time when infection and thrombocytopenia were detected and stored until assay. Bacterial infection was confirmed by blood cultures in five patients and by tracheal cultures in five. Median Tpo levels of term controls were lower than those of preterm controls (62 pg/mL vs. 87 pg/mL) (p <0.05). Median Tpo levels of thrombocyopenic preterm patients were higher than the levels of healthy preterms (258 pg/mL vs. 87 pg/mL) (p <0.05). Similarly, median Tpo levels of sick terms were significantly higher than those of healthy term controls (209 pg/mL vs. 62 pg/mL) (p <0.001). There was not significant difference between the median Tpo levels of term and preterm babies with infection (258 pg/mL vs. 209 pg/mL) (p >0.05). There was no correlation between platelet counts and Tpo levels in both term and preterm groups. The results of our study show that healthy term and preterm babies have detectable levels of Tpo and preterm babies have higher Tpo levels than term infants. Although thrombocytopenic babies with infection have increased levels of Tpo, these levels are still lower than the levels of thrombocytopenic children/adult patients and there seems to be no correlation between platelet counts and thrombopoietin levels. So our observation of increased Tpo levels may still be inadequate for normal platelet production in this period. and this group of babies may also be candidates for the administration of recombinant human Tpo.
