Pediatric Allergy and Immunology | Year: 2013
Background: In the last decade, there have been an increasing number of studies on achieving tolerance to foods by specific oral tolerance induction (SOTI). Still, the underlying mechanism of SOTI is unknown. Our aim was to describe changes in CD63 expression on basophils following in vitro Ag-specific stimulation by basophil activation test (BAT), after SOTI with egg in a pediatric population. Methods: Ten children with persistent allergy to egg were included. Skin prick tests (SPTs) and open food challenges (OFCs) were performed before SOTI. Specific IgE determination and BAT with egg white (EW), ovomucoid (OM), and ovalbumin (OVA) were performed before and after 1 month of the buildup phase of SOTI. Results: Total tolerance to egg was achieved in 9 cases and partial in one. After SOTI, there was a significant decrease in mean specific IgE levels (p < 0.05). CD63 expression also decreased (p < 0.05) in all patients. Conclusion: Decrease in Ag-specific basophil responsiveness is associated with the development of clinical tolerance by SOTI. © 2013 John Wiley & Sons A/S.

To present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the year 2013.From January 1st to December 31st 2013 data was recorded for the HEN registry and further descriptive and analytical analysis was done.In this period 3 223 patients (50.6% men) and a total of 3 272 episodes of HEN were registered in 33 Spanish hospitals. The rate of prevalence was of 67,11 patients/million habitants/ year 2013. A high percentage of patients (98,24%) were older than 14 years. Adults mean age was 69,14 years (sd 17,64) and men were younger than women p-value <0,001. Children mean age was 2,38 years (sd 4,35). The most frequent indication for HEN was neurological disease for children (49,1%). and for adults (60,6%). Gastrostomy was the most used administration route for children (51%) while younger ones were fed with NGT (p-value 0,003) also older adults (48%) were fed with this type of tube (p-value <0,001). The most frequent reasons for cessation of treatment was death, 44,4% were children and 54,7% were adults.The number of patients and hospitals registered increased in the last years while the other variables maintain steady. The registry developed allowing contrasted analysis of data in order to get more information.

To communicate the results of the Spanish Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE group for the year 2013.Data was recorded online by NADYA group collaborators that were responsible of the HPN follow-up from 1st January to 31st December 2013.A total of 197 patients and 202 episodes of HPN were registered from 35 hospitals that represents a rate of 4,22 patients/million habitants/year 2013. The median age was 53 years (IQR 40-64) for 189 adult patients and 7 months (IQR 6-35,5) for children. The most frequent disease in adults was neoplasm (30,7%) followed by other diseases (20,1%) and mesenteric ischemia (12,7%). Short bowel syndrome and intestinal obstruction (25,9%) were in 35.7% cases the indications for HPN. The most frequent diagnosis for children were the congenital intestinal disorders and other diagnosis, both with a (37,5%) and short bowel syndrome and intestinal obstruction were the indication for treatment, each was present in 50% of the sample. Tunneled catheters (50%) and subcutaneous reservoirs (27,7%) were frequently used. The septic complications related with catheter were commonly frequent with a rate of 0.74 infections/1000 HPN days. HPN duration presented a median of 1,69 days. A total of 86 episodes finalized during the year, death was the principal reason (45%), followed by resumed oral via (43,75%) while it happened inversely for children, 66,7% of them resumed oral via and 16,7% deceased. Fifteen per cent were considered for intestinal transplant, children were proportionally candidates, p-value 0.002.The number of participating centers and registered patients increased progressively respect to preceding years. Since 2003 Neoplasm is still being the principal pathological group. Death is adults principal reason for finalizing HPN and resuming oral via for children. Despite that NADYA registry is consolidate as a essential source of relevant information about the advances in Home Artificial Nutrition in our country, currently is in an improvement process of the available information about patients characteristics with a special emphasis on children even though they still being a minority group.

Genes Chromosomes and Cancer | Year: 2011
Chronic lymphocytic leukemia (CLL) cells are characterized by several chromosomal lesions. Some of these aberrations imply chromosome breaks as a result of unrepaired double strand breaks (DSBs) in the DNA. The ATM (ataxia telangiectasia-mutated) protein is the principal integrator of cellular responses to DSBs. ATM deletion is also an adverse prognostic factor in CLL. Taking this into account, we evaluated if genetic and/or epigenetic variation in the ATM gene may modulate the individual susceptibility to develop CLL. Our case-control association study was performed in a large Spanish population of 1,503 individuals, including 742 patients with CLL and 761 controls. We identified one haplotype within the ATM gene that confers an increased risk of CLL development (OR = 1.33; 95% CI: 1.10-1.60). Two polymorphisms of this ATM haplotype eliminated one CpG site each in Introns 15 and 61, causing changes in DNA methylation pattern. These data provide the first evidence for the existence of a putative "hepitype" in the ATM gene associated with CLL risk. © 2011 Wiley-Liss, Inc.

Olive (Olea europaea) pollen constitutes one of the most important allergen sources in the Mediterranean countries and some areas of the United States, South Africa, and Australia. Recently, we provided evidence that olive pollen releases nanovesicles of respirable size, named generically pollensomes, during in vitro germination. Olive pollensomes contain allergens, such as Ole e 1, Ole e 11, and Ole e 12, suggesting a possible role in allergy. The aim of this study was to assess the contribution of pollensomes to the allergic reaction. We show that pollensomes exhibit allergenic activity in terms of patients' IgE-binding capacity, human basophil activation, and positive skin reaction in sensitized patients. Furthermore, allergen-containing pollensomes have been isolated from three clinically relevant nonphylogenetically related species: birch (Betula verrucosa), pine (Pinus sylvestris), and ryegrass (Lolium perenne). Most interesting, pollensomes were isolated from aerobiological samples collected with an eight-stage cascade impactor collector, indicating that pollensomes secretion is a naturally occurring phenomenon. Our findings indicate that pollensomes may represent widespread vehicles for pollen allergens, with potential implications in the allergic reaction. © 2015 by The American Association of Immunologists, Inc.

To analyze if the true number of BCG instillations applied in non-muscle invasive bladder tumors has any influence on their prognosis as well as other tumor and clinical characteristics: age, sex, different protocols, BCG dose, whether primary or recurrent, solitary or multiple, tumor size G3 or Cis.A total of 324 high grade NMIBC (15 TaG3, 184 T1G3, 125 Cis) out of 1491 cases included in the CUETO database were analyzed. Following 6 post transurethral resection (RTU) BCG instillations, the patients were scheduled to receive one instillation every two weeks (3-6 times), for a total of 9-12 instillations. One third of the dose (27 mg) (112 cases) or total dose of 81 mg (212 cases). Mean follow-up was 59.6 months. Statistical Analysis: Kaplan-Meier, Cox-regression (uni-multivariate).A higher level of recurrence (p = 0.032) and progression (P = .013) risk as well as worse Ca-specific survival (P = .005) were obtained if there were fewer than 12 instillations with the Kaplan-Meier and Cox-regression multivariate analysis. A 27 mg (P = .008) dosage and being a female (P < .001) were independent factors for a higher recurrence risk, but not for progression or Ca-specific survival. The remaining characteristics studied were not statistically significant.In accordance with the results obtained, we can conclude that the number of BCG instillations applied has some influence on the outcome of high grade NMIBC. The optimum number of instillations as well as their time of application must still be determined. A dose of 27 mg and being a female are predictive factors of recurrence.

Flow cytometry (FCM) ismore sensitive than conventional cytology for detection of occult leptomeningeal lymphoma; however, some FCM-negative patients show central nervous system (CNS) recurrence. Here, we evaluated the cerebrospinal fluid (CSF) levels of 13 B-cell-associated markers and their contribution to the diagnosis of CNS lymphoma in 91 diffuse large B-cell lymphomas (DLBCL) and 22 Burkitt lymphomas (BLs). From all markers tested, CD19 wasthe most informative. Thus, higher soluble CD19 (sCD19) levels were associated with a greater frequency of neurological symptoms in DLBCL and BL and with parenchymal CNS lymphoma in DLBCL; sCD19 emerged as a powerful predictor of event-free and overall survival in DLBCL and BL, particularly when combined with FCM detection of CNS disease. These results support the utility of combined FCM detection of lymphoma cells and assessment of sCD19 levels in CSF, for more accurate identification of CNS disease in DLBCL and BL patients. © 2014 by The American Society of Hematology.

Expert Opinion on Drug Safety | Year: 2015
Objective: Aflibercept increased overall survival with acceptable tolerability in metastatic colorectal cancer (mCRC) when it was used in combination with FOLFIRI after progression on a first-line oxaliplatin regimen (VELOUR study). The safety profile of aflibercept in day-to-day clinical practice was assessed.Design and methods: A named patient program provided early access to aflibercept to mCRC patients in Spain before its commercialization. Patients received aflibercept 4 mg/kg intravenous + FOLFIRI every 2 weeks as second-line treatment. A descriptive safety analysis was conducted.Results: Data from 89 mCRC patients were analyzed (male: 61.8%; median age: 62 years [interquartile range: 55, 67]; Eastern Cooperative Oncology Group 0-1: 95.5%). Fifty four (60.7%) patients presented ≥ 2 metastasis [liver (83.1%), lung (44.9%) or lymph nodes (33.7%)]. Most patients had previously received bevacizumab (60.7%) or anti-EGFR (19.1%) therapy. Patients received a median of 6.0 (interquartile range: 4, 13) cycles of FOLFIRI + aflibercept. Most grade ≥ 3 adverse events (AEs) were reported during the initial cycles of treatment. AEs possibly related to treatment occurred in 39 (43.8%) patients. Common grade ≥ 3 treatment-related AEs were neutropenia (7.9%), diarrhea (4.5%) and hypertension (3.4%).Conclusions: In clinical practice, aflibercept + FOLFIRI is well tolerated, with a manageable toxicity profile. The safety results confirm the findings from the confirmatory VELOUR trial. © Informa UK, Ltd.

This study investigates whether the response criteria proposed by the European LeukemiaNet (ELN) to evaluate cytoreductive therapies in essential thrombocythemia (ET) correlate with clinically relevant outcomes in patients receiving anagrelide. We evaluated 154 ET patients treated with anagrelide (upfront in 87) for a median of 2.9 years. Complete response (CR), partial response, and no response were observed in 56, 30.5, and 13.5 % patients, respectively. Only 38 patients (25 %) achieved a sustained CR. Overall, the aggregated time on CR and without CR was 200.1 and 333.6 person-years, respectively. The incidence rate of thrombosis and hemorrhage was independent of the CR status. The only factor associated with shorter survival after anagrelide start was the patient's age, whereas achieving a CR with anagrelide had no predictive value for subsequent survival. In conclusion, CR according to the ELN definition is not associated with any measurable clinical benefit in ET patients treated with anagrelide. © 2013 Springer-Verlag Berlin Heidelberg.
