Infantile pyknocytosis (IP) is a rare hematological entity of newborns. It is a form of hemolytic anemia with unusual red cell morphology: the red blood cells are distorted, irregular, and small with many projections. Spontaneous resolution usually occurs by 4-6months of age. OBSERVATION: We describe the clinical features and biological parameters of 5 cases of IP. The first symptoms were always early jaundice, which required phototherapy. Anemia was severe in all babies and red blood cell transfusion was needed. CONCLUSION: IP is a rare cause of neonatal anemia whose diagnosis is based on a careful peripheral blood smear examination. In our study, anemia was severe and required red blood cell transfusion. Ethnic specificity and familial occurrence are reported in our experience. [less ▲]Detailed reference viewed: 335 (16 ULg)

Primary gastric lymphoma is a rare event in childhood. We describe a 13-year-old boy with gastric Burkitt-like lymphoma localized in the fundus. Symptoms mimicking gastritis-epigastric pain, hypochromic anemia, anorexia, and weight loss had been present for a few months before diagnosis. No Helicobacter pylori infection was shown at diagnosis. Biopsies obtained by ultrasound gastroscopy proved the diagnosis; F-fluorodeoxyglucose-positron emission tomography detected an isolated large gastric hypermetabolic mass. According to the international FAB/LMB 96 trial, the patient was treated with chemotherapy alone and is in first complete remission 2(1/2) years after diagnosis.

In this retrospective study, we analyse epidemiology, clinical symptoms and therapeutic results in a group of 23 children with neuroblastoma. Half of them were less than 2 years of age; in 19 of 23, the primitive tumour was abdominal; 35% of them were initially metastatic. The overall survival was 83% at 5 years and the event free survival, 75% at 5 years. Pronostic factors are age, extension of the disease at diagnosis, biologic parameters and genetic study of the neuroblast cells (amplification of N-myc oncogen). Our study shows the deleterious effect of bone lesions. [less ▲]Detailed reference viewed: 172 (4 ULg)

BACKGROUND: Donor lymphocyte infusion (DLI) is currently standard therapy for relapse of malignancies after allogeneic BMT. Several observations suggest that both normal and leukemic progenitor cells of host origin constitute effective target cells for donor-derived lymphocytes. To prevent relapse of sickle cell disease (SCD), a child with evidence of decreasing mixed chimerism received DLIs 8 months after allogeneic BMT for SCD. CASE REPORT: A 4-year-old child who was homozygous for SCD underwent a transplantation of bone marrow from his fully HLA-matched sister. Routine detection of sex chromosomes in bone marrow cells evidenced decreasing mixed chimerism, which heralded a probably imminent recurrence of the disease. The patient received two DLIs in graded incremental doses on Days 234 and 267. One month later, he developed grade 2 acute GVHD that responded well to corticosteroids and cyclosporine. RESULTS: DLI resulted in complete donor chimerism within 2 months of the second infusion. Now, 2 years after the second DLI, the patient is in excellent condition, with normal Hb and excellent growth and development. CONCLUSION: This is the first report of successful use of DLI in a patient with probable imminent SCD recurrence after allogeneic BMT. It shows that DLI can displace residual host HPCs in case of recurrence of nonmalignant disease after allogeneic BMT. [less ▲]Detailed reference viewed: 29 (3 ULg)

BACKGROUND AND OBJECTIVE: We reviewed all unrelated donor bone marrow transplants (UDBMT) performed in Belgium up to December 1995 to identify prognostic factors for relapse, transplant-related mortality and survival. DESIGN AND METHODS: A total of 163 UDBMT were performed in 92 males and 71 females aged 1-55 (median 26) years. Patients were transplanted for ALL (n=35), AML (n=34), CML (n=51), other myeloid malignancies (n=14), SAA (n=21) or miscellaneous other diseases (n=8). Most patients had advanced disease; a few patients were in CR1 (n=10) or early chronic phase (CP) of CML (n=5). RESULTS: Overall survival at 5 yrs was 17% (95% confidence interval: 8-32%), but survival was significantly better for patients with non-malignant disorders (55% at 4 yrs). The relapse rate +/-SE was projected to be 40 (28-54)% at 5 yrs, 36 (20-56)% for standard-risk and 68 (43-85)% for high-risk malignancies (p=0.0029). There was no relapse in CML patients transplanted in 1st CP compared to 68% at 4 yrs with more advanced CML (p=0.0033). Grade II-IV acute graft-versus-host disease (aGVHD) occurred in 55% by day 100 and was strongly modulated by age, ranging from 41% in <20-yr-old to 80% in >40-yr-old patients (p=0. 0021). Transplant-related mortality (TRM) was projected to be 72 (52-87)% at 5 yrs including 2 very late deaths from lung fibrosis and secondary cancer. Main causes of death were original disease in 27, secondary malignancy in 2, GVHD in 28, interstitial pneumonia in 21, other infections in 19, and miscellaneous toxic causes in 21 patients. In multivariate analysis, the relapse rate was strongly dependent on the disease status (p=0.0029), TRM being significantly worse with older age (p=0.0049), and overall survival being significantly worse in more advanced disease (p=0.0006), after a second transplant (p=0.0166), in centers of smaller size (p=0.0316) and in older patients (NS). INTERPRETATION AND CONCLUSIONS: Although results have improved somewhat in recent years, UDBMT remains a procedure with a high TRM. UDBMT should be performed in patients with less advanced diseases and in centers with more experience, particularly in the treatment of adult patients. [less ▲]Detailed reference viewed: 83 (6 ULg)

Fifty patients affected by sickle cell anaemia underwent transplantation of HLA-identical haematopoietic stem cells (bone marrow, 48; cord blood, 2). Two groups of patients were considered for transplantation. Group 1 included 36 permanent residents of a European country who, retrospectively, met the inclusion criteria accepted at a consensus conference held in Seattle in 1990, wherein children were selected because they already had evidence of a morbid course. Group 2 included 14 patients who were transplanted earlier, had not received more than three blood transfusions and were transplanted because they had decided to return to their country of origin. Kaplan-Meier estimates of overall survival, event-free survival and disease-free survival at 11 years of the whole grafted population are 93, 82 and 85%, respectively. In group 1, overall survival, EFS and DFS were 88, 76 and 80% and in group 2, 100, 93 and 93%, respectively. Clinical manifestations of the disease, as well as disease associated haemolytic anaemia, disappeared in all successfully treated patients. Recovery of spleen function was present in seven out of 10 evaluated patients. Adverse events (death, absence of engraftment, mixed chimerism and relapse) occurred more frequently in group 1 than in group 2 (25% vs 7%, P< 0.001). Acute graft-versus-host disease (GVHD) was present in 20 patients (grade I or II, 19; grade III, 1), chronic GVHD in 10 (limited, 7; extensive, 3). One patient developed an acute myeloid leukaemia. Gonadal dysfunction was present in all patients (six boys and eight girls) transplanted close to or after puberty, although transient in one adolescent girl.
