Abstract
Wiskott-Aldrich syndrome (WAS) is a rare X-linked immunodeficiency with microthrombocytopenia, eczema, recurrent infections, autoimmune disorders, and malignancies that are life-threatening in the majority of patients. In this long-term, retrospective, multicenter study, we analyzed events that occurred in 96 WAS patients who received transplants between 1979 and 2001 who survived at least 2 years following hematopoietic stem-cell transplantation (HSCT). Events included chronic graft-versus-host disease (cGVHD), autoimmunity, infections, and sequelae of before or after HSCT complications. Three patients (3%) died 2.1 to 21 years following HSCT. Overall 7-year event-free survival rate was 75%. It was lower in recipients of mismatched related donors, also in relation with an older age at HSCT and disease severity. The most striking finding was the observation of cGVHD-independent autoimmunity in 20% of patients strongly associated with a mixed/split chimerism status (P < .001), suggesting that residual-host lymphocytes can mediate autoimmune disease despite the coexistence of donor lymphocytes. Infectious complications (6%) related to splenectomy were also significant and may warrant a more restrictive approach to performing splenectomy in WAS patients. Overall, this study provides the basis for a prospective, standardized, and more in-depth detailed analysis of chimerism and events in long-term follow-up of WAS patients who receive transplants to design better-adapted therapeutic strategies.

Abstract
OBJECTIVE The aim of this study was to investigate the nutritional status of children on continuous ambulatory peritoneal dialysis (CAPD) and to relate it to the dose of dialysis and serum levels of inflammatory cytokines and insulin-like growth factor-1 (IGF-1). PATIENTS 17 CAPD patients (8 girls, 9 boys; mean age 13.1 +/- 3.5 years, median 15 years) were included in the study. Anthropometric measurements and serum albumin levels were used in the evaluation of nutritional status. Serum interleukin (IL)-1beta, IL-6, tumor necrosis factor alpha, and IGF-1 levels were determined in all CAPD patients and in a healthy control group. Weekly Kt/V and creatinine clearance (CCr) were measured to determine adequacy of dialysis. RESULTS The mean dialysis period was 23.7 +/- 15.2 months (median 23 months). Anthropometric measurements and serum albumin level were as follows: height 130.2 +/- 15.6 cm, height standard deviation score (HtSDS) -4.2 +/- 2.4, body mass index (BMI) 16.3 +/- 1.6 kg/m2, body mass index standard deviation score (BMISDS) -0.8 +/- 0.9, triceps skinfold thickness (TST) 4.2 +/- 1.4 mm, midarm circumference (MAC) 16.21 +/- 2.3 cm, upper arm muscle area (AMA) 1799.1 +/- 535.7 mm2, upper arm fat area (AFA) 334.5 +/- 143 mm2, and serum albumin 3.1 +/- 0.7 g/dL. The BMI was above the fifth percentile in all patients; TST and MAC were below the fifth percentile in 14 patients (82.4%) and 10 patients (58.8%) respectively. The AMA was below the fifth percentile in 8 patients; however, the AFA was below the fifth percentile in all patients. Mean serum albumin level was under 3.5 g/dL in 70.5% of the children. We found significant positive correlations between BMI and Kt/V (r = 0.69, p < 0.01), CCr (r = 0.64, p < 0.05), and IL-6 (r = 0.61, p < 0.01). There was an inverse correlation between BMISDS and dialysis period (r = -0.58, p < 0.05); and between IL-6 and serum albumin (r = -0.49, p < 0.05). A significant positive correlation between BMISDS and serum IGF-1 level (r = 0.62, p < 0.01) was noted. We also found a significant positive correlation between serum IGF-1 level and both HtSDS (r = 0.57, p < 0.05) and TST (r = 0.52, p < 0.05). Significant positive correlations between AFA and CCr and IGF-1 were also noted (both r = 0.56, p < 0.05). CONCLUSION Although many factors may be responsible for malnutrition and growth retardation, we found that prolonged period of dialysis, inadequate dialysis, and low IGF-1 levels are the most important risk factors in CAPD patients.

Abstract
Major histocompatibility complex class II (MHCII) deficiency is a primary immunodeficiency resulting from defects in one of four different MHCII-specific transcription factors-CIITA, RFX5, RFXAP, and RFXANK. Despite this genetic heterogeneity, the phenotypical manifestations are homogeneous. It is frequently difficult to establish a definitive diagnosis of the disease on the basis of clinical and immunological criteria. Moreover, the phenotypical homogeneity precludes unambiguous identification of the regulatory gene that is affected. Identification of the four genes mutated in the disease has now allowed us to develop a rapid and straightforward diagnostic test for new MHCII-deficiency patients. This test is based on direct correction of the genetic defect by transduction of cells from patients with lentiviral vectors encoding CIITA, RFXANK, RFX5, or RFXAP. We have validated this approach by defining the molecular defects in two new patients. The RFXANK vector restored MHCII expression in a T cell line from one patient. The RFXAP vector corrected primary cells (PBL) from a second patient. Molecular analysis confirmed the presence of homozygous mutations in the RFXANK and RFXAP genes, respectively. Direct genetic correction represents a valuable tool for the diagnosis and classification of new MHCII-deficiency patients.

Abstract
BACKGROUND Various immunological abnormalities leading to impaired immune status have been described in uraemic adults; however, few data are available for uraemic children. METHODS In this study, peripheral blood total lymphocyte count and lymphocyte subsets (CD3+, CD4+, CD8+, CD16+, CD20+) were evaluated, skin tests with PPD and Candida antigens were performed, and serum immunoglobulin (IgG, IgA, IgM) and complement (C3, C4) levels were measured in 30 children with end-stage renal failure (10 before dialysis, 10 on continuous ambulatory peritoneal dialysis, and 10 on haemodialysis) and the results compared with those of 15 healthy controls. RESULTS The data showed significant lymphopenia in predialysis and haemodialysis groups. No significant change was observed in the CD4+/CD8+ ratio or in the percentages of lymphocyte subsets in either group studied, while the absolute values of some lymphocyte subsets were significantly lower in all groups as compared with controls. In skin test evaluation, only the patients in the predialysis group showed a significantly decreased response to Candida antigen. The serum immunoglobulin levels were significantly decreased in the continuous ambulatory peritoneal dialysis group as compared with the control group. CONCLUSION Our results, together with those of other paediatric studies, reported in the literature, suggest that uraemic children are not immunocompromised, though the effects of uraemia may cause some variation in their immune status.

Abstract
BACKGROUND The CD44, a cell surface proteoglycan, participates in a variety of function including tumor dissemination and metastasis. However, there are no available data on the prognostic significance of CD44 expression of tumor tissue correlated with serum sCD44 level in childhood leukemias and lymphomas. METHODS Serum levels and leukemic cell tumor tissue expression of CD44 were detected in 54 children with acute leukemia and malignant lymphoma. Serum samples were obtained from all patients before treatment and during remission. Twelve age-matched healthy children were included as a control group. RESULTS The serum CD44 levels were significantly higher in patients with Hodgkin's disease (HD), non-Hodgkin's lymphoma (NHL), Burkitt's lymphoma (BL) and acute lymphoblastic leukemia (ALL) than those in the control group. The median values were 1627.0, 1336.0, 1318.5, 1730.4, 902.7 ng/mL, respectively, and P<0.001, P<0.01, P<0.01, P<0.05 in comparisons, respectively. However, there was no significant difference between acute myeloid leukemia (AML) and the control group (median values: 900.3 and 902.7 ng/mL, respectively, P>0.05). Serum sCD44 levels significantly declined in HD, NHL and ALL patients who were in complete remission (median values: 684.0, 573.8 and 1101.1 ng/mL, respectively, P<0.05 in each comparison). Patients with HD had higher levels of serum sCD44 and correlated well with higher erythrocyte sedimentation rate (ESR), B-symptoms and advanced-stage disease (P<0.05, P<0.05 and P<0.01, respectively). Expression of CD44 was significantly high in patients with HD and NHL who were in advanced stages of disease. High serum CD44 level was also associated with high tumor tissue expression of CD44 in patients with HD and BL. In addition, patients with higher levels of serum sCD44, had a poorer outcome and survival than those with lower sCD44 levels in HD and NHL groups. CONCLUSIONS A high serum sCD44 level and/or tumor tissue expression at diagnosis is associated with poor prognostic criteria and/or unfavorable outcome in childhood leukemias and lymphomas.

Abstract
Serum levels and leukemic cell-tumor tissue expression of intracellular adhesion molecule-1 (ICAM-1/CD 54) were detected in 54 children with acute leukemia and malignant lymphoma. Serum samples were obtained from all patients before treatment and after cessation of the therapy from malignant lymphoma cases and during remission from leukemic patients. Twelve age-matched healthy children were included as a control group. The serum ICAM-1 levels were significantly higher in patients with acute lymphoblastic leukemia (ALL) or Hodgkin's disease (HD) than those in the control group (median values: 350.9, 286.4, and 138.4 ng/mL, respectively; P < .01 in each comparison). However, there were no significant differences concerning serum ICAM-1 levels between the control group and each of the acute myeloid leukemia (AML), non-Hodgkin's lymphoma (NHL), and Burkitt's lymphoma (BL) case groups (median values: 235.7, 222.7, 195.9, and 138.4 ng/mL, respectively; P > .05 in each comparison). Moreover, serum soluble ICAM-1 levels significantly declined in ALL or HD patients who were in complete remission (median values: 185.0 and 145.4 ng/mL, respectively; P < .05 in each comparison). In HD patients high levels of serum ICAM-1 could be correlated with high ESR (P < .01), whereas no statistically significant difference could be found when serum ICAM-1 titers were compared with stages, B symptoms, and histological subgroups, probably because of the inadequate number of patients in each group. Expression of ICAM-1 was mainly attributed to lymphocytes, vessels, and weakly to Hodgkin's cells, and this was significantly high in patients who were in advanced stages of disease. High serum sICAM-1 level was also associated with poor outcome and survival. Determination of serum level and/or tumor tissue expression of ICAM-1 in HD and ALL might represent an additional, but probably not independent, disease-associated marker to be used in the evaluation and/or monitoring of treatment response in patients with HD and ALL.

Abstract
A total of 54 previously untreated patients (15 girls, 39 boys) with poor growth due to idiopathic growth hormone deficiency (IGHD) were treated with human growth hormone (hGH), continuously up to 4 years. All of the patients had a peak hGH level which was below 10 ng/mL after at least two pharmacological tests and/or blunted physiologic hGH secretion, and their height was below -2.5 s.d. for age and gender. After the 1st year of therapy, height velocity (HV) increased significantly when compared with baseline (from 3.18 +/- 0.76 cm/year to 9.17 +/- 1.03 cm/year; P < 0.001), declined during the 2nd year and then remained significantly higher than pretreatment HV. When considering improvement in height expressed by height standard deviation score (SDS), during the therapy all of the patients showed a significant gain +/- 1.72 +/- 1.09 (from -4.11 +/- 0.61 to -2.21 +/- 0.48). The height values were significantly higher than pretreatment, but remained below -2 s.d. after 4 years of hGH therapy in our patients. Increased height velocity has been sustained, but height improvement after therapy was inversely correlated to height SDS for chronological age of patients at the start of therapy. In conclusion post-treatment height has been shown to be related to height deficit at the beginning of therapy. Therapy was well tolerated with no local or systemic adverse effects or acceleration of bone age.
