[Clinical consequences of alpha-thalassemia in the Basque Country, Spain. Impact of neonatal screening]. An Pediatr (Barc) 2014; 83:85-8. [PMID: 25483992 DOI: 10.1016/j.anpedi.2014.10.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2014] [Revised: 10/02/2014] [Accepted: 10/20/2014] [Indexed: 10/24/2022] Open
Abstract
INTRODUCTION Alpha-thalassemia is the most common hemoglobinopathy with a variable clinical manifestation depending on the number of allele mutations (asymptomatic/mild anemia if 1-2 allele mutations, severe disease if 3-4 allele mutations). A study was conducted from May 2011 on hemoglobinopathies found in the neonatal screening in the autonomous community of the Basque Country (CAPV). OBJECTIVES To analyze the impact of alpha-thalassemia in this area and the effectiveness of its neonatal screening. METHODS A review was made of patients with a positive gene study for alpha-thalassemia over a 2-year period (2012-2013) and an analysis was made of the age at diagnosis, ethnic group, analytical result, and treatment. RESULTS The genetic study was performed on 107 patients, of which 61 had some mutation, with 62% having one allele mutations and 38% with two alleles. The mean age at diagnosis was 31 years, with 28% being younger than eighteen years old. Most of the patients were European with a significant number of Africans (26%) and Arabs (13%). All patients were asymptomatic, and 28% had mild anemia. Two patients were diagnosed by neonatal screening. Most of them did not need any treatment or only required iron therapy. CONCLUSIONS The detection of one or two alpha gene mutations has no clinical impact, but allows genetic counseling. No patient was found with 3-4 mutations or severe symptoms in our region. Contrarily to the diagnosis of other diseases, our results does not support that routine neonatal screening for alpha-thalassemia has any clinical impact in our community.

Abstract
PURPOSE To assess the efficacy and safety of liposomal cytarabine in the treatment of de novo and relapsed leptomeningeal involvement in children with primary CNS tumours. METHODS Data from clinical charts were entered into a database for consecutive unselected patients (n=20) from nine Spanish centres. Diagnosis of leptomeningeal involvement was confirmed by cytology, MRI and/or CT scan. The dose of liposomal cytarabine used varied from 20 to 50 mg, by age. RESULTS There were 8 females and 12 males, mean age 7.3 years (range 8 months to 18 years). The tumours were: 10 medulloblastomas, 4 ependymomas, 3 primitive neuroectodermal tumours and 3 other tumours. Fourteen had undergone previous chemotherapy and 12 radiotherapy. Nine received concurrent chemotherapy and 2 concurrent radiotherapy. Median follow-up was 244.5 days (range 12- 869). Patients received a median of 5 doses (range 1-9) of liposomal cytarabine. A neurological response (complete or partial) was seen in 11/19 (58%) and a cytological response in 7/10 (64%). Median time to neurological progression exceeded 180 days (range 12-869). Adverse effects were reported in 11/20 patients, but none was grade IV. DISCUSSION Liposomal cytarabine was well tolerated and efficacious in this patient group, but prospective randomised trials are needed.

Abstract
BACKGROUND Stage 4 and MYCN amplified (MNA) neuroblastoma in children have a poor prognosis. Our aim was to increase initial and long-term response in this population. PROCEDURE High-risk children were studied according to the International Neuroblastoma Staging System, then treated with high-dose cyclophosphamide and high-dose carboplatin, followed by surgery and autologous stem cell transplant or maintenance chemotherapy. RESULTS From June 1992 to December 1998, 83 children were admitted in the study (72 stage 4> 1 year, 5 stage 4 MNA infants, and 6 MNA stage 3 children); tumor tissue was obtained from 73, MYCN was performed in 65, being amplified in 21 (32%). Induction chemotherapy was administered in the expected time in 35% of patients. Its toxicity was mainly hematologic followed by infections, and there were 3 chemotherapy-related deaths. Delayed surgery was performed on 60 patients with complete or >90% resection in 80% of cases. Chemotherapy plus surgery produced some response in 90% of patients, 53% were in CR/VGPR; 49 children received autologous SCT, and 16 received maintenance chemotherapy for 9 months. Follow-up ranges are 1-87 months, mean 30 months. S and EFS at 4 years are 0.33 (SD 0.02). CONCLUSIONS High-dose cyclophosphamide and high-dose carboplatin are effective in the initial treatment of neuroblastoma; combined with surgery they produce some response in most patients. Nevertheless, the CR/VGPR rate reaches only 53%. Survival time has also been prolonged but most patients relapse with metastases.

Abstract
Mutation analysis of retinoblastoma is considered important for genetic counseling purposes, as well as for understanding the molecular mechanisms leading to tumors with different degrees of penetrance or expressivity. In the course of an analysis of 43 hereditary retinoblastoma Spanish patients and kindred, using direct PCR sequencing, we have observed 29 mutations; most of them (62%) have not been reported previously. Of the mutations, 69% correspond to nonsense mutations (mainly CpG transitions) and frameshifts, with the expected outcome of a truncated Rb protein that lacks the functional pocket domains and tail. The remainder corresponds to splicing mutations, most of them (62%) targeted to invariant nucleotides, with the predicted consequence of out of frame exon skipping. Two of the splicing mutations in our study were found associated to families with a low-penetrance phenotype. Additionally, most of the mutations affecting splice junctions corresponded to retinoblastoma cases of either sporadic or hereditary nature with delayed onset (32 months on average). In contrast, most of the nonsense and frameshift mutations are associated with an early age at diagnosis (8.7 months on average). These differences are discussed in the context of the relationships between genotype and low expressivity phenotype. The differences in the spectrum of RB1 mutations found in this and other European surveys are also discussed in the context of alternate DNA methylation and mismatch repair phenotypes.

Abstract
BACKGROUND Prognosis of relapsed and refractory neuroblastoma is uniformly fatal; new therapeutic approaches are needed. PROCEDURE Relapsed and refractory neuroblastoma patients were treated with continuous infusion chemotherapy combined with MIBG. RESULTS Over 4 years, 35 heavily pretreated patients were registered, 29 with bone or/and bone marrow metastases. Grade 3 or 4 hematologic toxicity was frequent, without toxic deaths. Sixteen patients responded. The probability of 5-year overall survival was 0.19. CONCLUSIONS This approach is feasible and toxicity manageable; it rescued some patients and prolonged their survival. It merits assay in newly diagnosed high-risk neuroblastoma patients.

Abstract
Interferon-alpha (IFN-alpha) is a biological response modifier with antiviral and tumoral effect that is used in the treatment of chronic myelogenous leukemias. Adverse effects are well documented and cardiovascular disturbances mostly include hypotension and tachycardia and rarely cardiomyopathy. We report on an infant with chronic myelomonocytic leukemia (CML) diagnosed at 3 months of age who was treated with increasing IFN-alpha dosage (2.5-5.5 million U/m2/day) given subcutaneously for 7.5 months. At that age, he presented anorexia, general malaise, and nocturnal sweating for about a week, followed by respiratory distress and tachycardia. Diagnosis of congestive heart failure was suspected and documented by cardiomegaly and echographic changes of left ventricular dilated cardiomyopathy, with a 40% left ventricular ejection fraction (EF) and 20% fractional shortening (FS). He was treated with digoxin, furosemide, and angiotensin converting inhibitors, and IFN-alpha was discontinued. Progressive improvement of cardiac function was observed within 7 months of the events with normalization of the echocardiographic findings (EF 60%, FS 31%). We should emphasize the possibility of severe and reversible cardiac toxicity of IFN-alpha in infancy.

Abstract
Varicella vaccine has shown its efficacy to prevent the disease and complications in healthy and immunodeficient children. In this article the authors evaluate the immunologic status of acute lymphoblastic leukaemia at diagnosis and at follow up and the development of chickenpox and/or herpes zoster. Children with negative serology and continuous complete remission of acute lymphoblastic leukaemia for one year were vaccinated. Of 71 children diagnosed of acute lymphoblastic leukaemia from 1983 to 1996, 25 received the vaccine and seroconversion was obtained in 76% after one dose and 92% after the second dose. Vaccine tolerance was adequate. The incidence of herpes zoster infection was decreased in vaccinated children during chemotherapy compared to the wild-virus infected ones. Nowadays that vaccine for healthy children is recommended, we consider a priority to protect from chickenpox the children affected by leukaemia that are in continuous complete remission of the disease.

Abstract
The aim of this study was to classify prospectively a series of neuroblastoma tumours according to the International Neuroblastoma Staging System (INSS) and the International Neuroblastoma Response Criteria (INRC) and to evaluate the difficulties and pitfalls involved in a multicentre setting. Each hospital provided their data for central review. The surgical procedures and their complications were reported. Kaplan-Meier estimates of survival and event-free survival were calculated according to stage and response to therapy. From June 1992 to December 1996, 194 patients were included in the study, with a mean age of 2 years. Initial studies were performed according to INSS recommendations without major problems. INSS stage was correctly applied to all patients except for 9 (95%). Post-operative complications were observed in 15 patients (8.3%). Response to therapy (INRC) was studied in 63 stage 4 patients, 11 of whom were not classified correctly (17%). Differences in survival according to stage (INSS) and group of response to therapy (INRC) were statistically significant (P < 0.001). In conclusion the INSS was easy to use and separated different prognostic groups. Surgical complications and mortality did not increase in this series because of using the INSS. The feasibility of INRC was evaluated in a small series of stage 4 patients and the designation of response was problematic in a relatively high proportion of cases. The prognostic value of the different responses was highly significant, but less informative than had been hoped for.

Abstract
UNLABELLED Fetal hydrops associated with neonatal tumours is an uncommon occurrence. The diagnosis can be established prenatally by ultrasound examination. The treatment of choice is surgery which may be curative. We report the case of a male born at 32 weeks gestation who presented with severe hydrops fetalis and a thoracic mass. The child could not be operated upon because of rapid clinical deterioration. The autopsy findings confirmed the diagnosis of congenital fibrosarcoma. This is, to our knowledge, the first case of hydrops fetalis associated with fibrosarcoma. CONCLUSION The association of hydrops fetalis and fibrosarcoma is an exceptional observation but can be added to the long list of differential diagnoses of non-immune hydrops.

Abstract
Although the acute renal toxicity of cisplatin has been well documented, long-term follow-up studies in cisplatin-treated children are scanty. We have evaluated the incidence and characteristics of both acute and chronic nephrotoxicity in 22 children (median age 8 years) treated with cisplatin as part of different chemotherapeutic protocols. All patients exhibited a significant and progressive decrease in plasma magnesium (Mg) values soon after cisplatin administration. Magnesiuria also increased immediately after therapy. Hypomagnesemia (plasma Mg < 1.4 mg/dl) occurred in 10 patients and it was dose-dependent. Minimal and mean cumulated doses inducing hypomagnesemia were 300 and 500 mg/m2, respectively. In 18 children we followed renal function prospectively for a mean time of 2.3 years after arrest of cisplatin therapy. Chronic hypomagnesemia and moderate elevation of plasma creatinine were observed in 6 children, hypocalciuria in 5 children, and hypokalemia in 1 child. Presence of hypomagnesemia was unrelated to the total dose received or the time elapsed since cisplatin therapy. Renal function studies, performed in the 6 children with chronic hypomagnesemia, revealed different degrees of impairment in Mg reabsorption. The functional characteristics of chronic cisplatin nephrotoxicity found in the present series-contrary to prior reports-are not comparable to those present in the inherited Gitelman's syndrome.

Abstract
Cerebral and meningeal involvement in patients with primary extracranial neuroblastoma (NB) is unusual although it is generally present in disseminated disease. The intensification of chemotherapy that has prolonged survival in these children has changed the pattern of relapse presentation, as occurs with isolated central nervous system (CNS) disease. We report 4 patients with secondary CNS metastases. Three infants of 16, 14, and 10 months of age, diagnosed with primary abdominal NB stage 4, presented neuromeningeal metastases during maintenance chemotherapy with seizures and cranial hypertension as the first manifestation. Another 8-year-old patient diagnosed with NB stage 3 presented local relapse with later neuromeningeal metastases. All died in the following 3 months. The possibility of CNS relapse in patients with NB should be considered when neurological symptoms and signs appear. These new relapse forms overshadow the prognosis of these children.

Abstract
The Spanish Neuroblastoma Study Group has conducted a study on advanced neuroblastoma (N-I-87), which included 33 stage III and 60 stage IV neuroblastoma children more than 1 year of age, enrolled between October 1987 and April 1992. They were staged according to Evans and treated with induction chemotherapy (IC) consisting of 3 courses of cyclophosphamide-doxorubicin alternating with 3 of high-dose cisplatin-teniposide. Evaluation after IC and surgery demonstrated an overall response rate of 88% for stage III and 69% for stage IV. In the latter, complete responses and good partial responses were 33 and 14%, respectively. After surgery, children received maintenance chemotherapy (all stage III except 2 and 30 stage IV) or autologous bone marrow transplantation (ABMT) (11 stage IV), the distribution was not randomised. Probability of survival at 5 years was 0.60 +/- 0.12 for stage III and 0.24 +/- 0.07 for stage IV. A significant difference in survival at 5 years was found between "good responders" and "non-responders" to initial chemotherapy.

Abstract
Seven cases of isolated atrial septal defect, "ostium secundum" type, are presented. All had clinical symptoms of congestive heart failure and represented five per cent of the cases studied in our department with atrial septal defect. In three patients associated extracardiac anomalies were found. All had cardiomegaly, increased pulmonary vascularity, right ventricular hypertrophy and splitted second sound. Echocardiographic findings were: paradoxal movement of the interventricular septum and ventricular dyastolic overflow. Medium left to right shunt was 3.08. In four cases a massive filling of the right atrium was obtained, through, the selective injection of contrast material, in the pulmonary artery. None of the patients, responded to medical treatment alone and five of then went to surgery with significant improvement, in their clinical manifestations, and normal growth and weight curves in their follow-up. Importance in survival of early surgery is emphasized.

Abstract
Nineteen infants suspected of having cow's milk protein-sensitive enteropathy were studied. They all showed failure to thrive, diarrhoea and/or vomiting when fed a diet of cow's milk, and improved when their diet was changed to casein hydrolysate. Jejunal biopsy was done before and 18--23 hours after a milk challenge. Of the 19 infants, 12 presented histological evidence of cow's milk protein intolerance. Eight suffered from vomiting and diarrhoea within 9 days of the milk challenge, but in 4 cases the histological abnormalities were not accompanied by clinical symptoms. In one case a chicken meat intolerance was documented. The histological appearance of the intestinal mucosa after chicken challenge was identical to that observed after milk challenge. In our opinion, repeated intestinal biopsies before and after an acute challenge is the best method to establish the diagnosis not only of cow's milk protein intolerance but also of intolerance to other alimentary proteins.
