Pediatric Pulmonology > 57 > 5 > 1196 - 1201

Objectives To study the clinical characteristics and impact of bronchoscopy in children from developing countries, referred for cardiac surgery, through the "Save a Child's Heart" (SACH) organization. Methods We performed a retrospective hospital‐chart review of SACH children (0–18 years old) referred between 2006 and 2021 who underwent fiberoptic bronchoscopy. We examined demographics,...

Asthma‐predictive‐index, bronchial‐challenge, sputum eosinophils in acutely wheezing preschoolers

Dorit Ater, Bat‐El Bar, Nir Fireman, Elizabeth Fireman, more

Pediatric Pulmonology > 49 > 10 > 952 - 959

BackgroundMost preschoolers with viral wheezing exacerbations are not atopic. AimTo test in a prospective controlled trial whether wheezing preschoolers presenting to the ED are different from the above in three different domains defining asthma: the atopic characteristics based on stringent asthma predictive index (S‐API), the characteristics of bronchial hyper‐responsiveness (BHR), and airway inflammation...

Eosinophilic esophagitis: an immune-mediated esophageal disease

Jenny Weinbrand-Goichberg, Idit Segal, Adi Ovadia, Arie Levine, more

Immunologic Research > 2013 > 56 > 2-3 > 249-260

Eosinophilic esophagitis (EoE) is an emerging disease defined by esophageal dysfunction, by typical endoscopic findings and by abnormal eosinophilic inflammation within the esophagus. Eosinophilic accumulation in the esophagus occurs as a result of esophageal overexpression of pro-inflammatory mediators, including T cells and mast cells, cytokines such as interleukin (IL)-13, IL-5 and IL-15, as well...

Defining combined immunodeficiency

Chaim M. Roifman, Raz Somech, Fotini Kavadas, Linda Pires, more

The Journal of Allergy and Clinical Immunology > 2012 > 130 > 1 > 177-183

Although the extreme condition of typical profound T-cell dysfunction (TD), severe combined immunodeficiency (SCID), has been carefully defined, we are currently in the process of better defining less typical T-cell deficiencies, which tend to present with autologous circulating T-cell combined immunodeficiency (CID). Because autologous cells might interfere with the outcome of bone marrow transplantation,...

Sesame Seed Food Allergy

Ilan Dalal, Michael Goldberg, Yitzhak Katz

Current Allergy and Asthma Reports > 2012 > 12 > 4 > 339-345

The number of reports regarding sesame seed food allergy (SFA) has increased significantly worldwide over the past two decades, either due to a genuine increase in SFA or merely an increase in its awareness. Its prevalence is difficult to estimate due to the lack of well designed prospective population-based studies. Based on the available data, we estimate that SFA affects 0.1–0.2 % of the population,...

The pendulum between food protein–induced enterocolitis syndrome and IgE‐mediated milk allergy

Aharon Kessel, Ilan Dalal

Acta Paediatrica > 100 > 10 > e183 - e185

The transition from milk protein–induced enterocolitis syndrome to IgE‐mediated milk allergy is uncommon. Herein, we describe three infants that suffered from recurrent vomiting and restlessness in response to cow’s milk formula with negative skin prick to milk and therefore diagnosed as milk protein–induced enterocolitis syndrome. After recovering and reintroducing cow’s milk formula, they developed...

Novel mutations in RAG1/2 and ADA genes in Israeli patients presenting with T-B- SCID or Omenn syndrome

Ilan Dalal, Diana Tasher, Raz Somech, Amos Etzioni, more

Clinical Immunology > 2011 > 140 > 3 > 284-290

The relative frequency of the different forms of SCID may vary in different countries. The most frequent form in Israel is the autosomal-recessive T-B- SCID or Omenn syndrome while X-linked SCID is rare. We report our immunological and genetic analyses in multicentre study of patients presenting with either T-B- SCID or Omenn syndrome. Among 16 patients, we identified 7 novel mutations in 6 patients...

Delta chemokine (fractalkine) – A novel mediator of pulmonary arterial hypertension in children undergoing cardiac surgery

Tomer Avni, Gideon Paret, Avner Thaler, David Mishali, more

Cytokine > 2010 > 52 > 3 > 143-145

Fractalkine (FKN), a unique chemokine associated with pulmonary hypertension, may be involved in the acute stress response that regulates inflammation after cardiopulmonary bypass (CPB) surgery. We characterized FKN levels and correlated them with clinical parameters in children undergoing cardiac surgery involving CPB.Twenty-seven consecutive patients, aged 30days to 11.5years, who underwent surgery...

Reduced central tolerance in Omenn syndrome leads to immature self-reactive oligoclonal T cells

Raz Somech, Amos J. Simon, Atar Lev, Ilan Dalal, more

The Journal of Allergy and Clinical Immunology > 2009 > 124 > 4 > 793-800

Omenn syndrome (OS) is characterized by a peculiar severe T-cell immune deficiency associated with autoimmunelike manifestations. Dysregulations of the central and peripheral immune tolerance, mediated by the protein autoimmune regulator (AIRE) and regulatory T cells, respectively, were proposed as possible mechanisms of this aberrant inflammatory process.We studied mechanisms of central and peripheral...

Natural history of food allergy in infants and children in Israel

Darit Aaronov, Diana Tasher, Arie Levine, Eli Somekh, more

Annals of Allergy, Asthma & Immunology > 2008 > 101 > 6 > 637-640

Knowledge about the natural history of food allergy, especially sesame, is scarce. To follow the natural history of food allergies in Israel, particularly of sesame allergy. The survey was conducted based on clinical records and a detailed questionnaire of children diagnosed as having food allergy. We found 234 children with suspected food allergy. Testing detected 283 allergies in 180 patients...

Congenital Patent Ductus Venosus: An Association with the Hyper IgE Syndrome

Keren Sagiv-Friedgut, Michaela Witzling, Ilan Dalal, Chana Vinkler, more

The Journal of Pediatrics > 2007 > 150 > 2 > 210-212

We describe an association between congenital patent ductus venosus and hyper immunoglobulin E syndrome in a pair of siblings. The possibility that this is a separate entity or a genetically linked association is discussed.

Matched unrelated bone marrow transplant for severe combined immunodeficiency

Chaim M. Roifman, Eyal Grunebaum, Ilan Dalal, Luigi Notarangelo

Immunologic Research > 2007 > 38 > 1-3 > 191-200

Severe combined immunodeficiency (SCID) is a lethal disease unless allogeneic bone marrow transplantation (BMT), preferably from a family related HLA identical donor (RID) is given. Previously, some patients received HLA-mismatched related donors (MMRD) BMT, which often resulted in slow immune reconstitution and variable survival. Alternatively, HLA-matched unrelated donors (MUD) BMT have been suggested...

Analysis of the interleukin-12/interferon-γ pathway in children with non-tuberculous mycobacterial cervical lymphadenitis

Francis Serour, Avraham Mizrahi, Eli Somekh, Jacqueline Feinberg, more

European Journal of Pediatrics > 2007 > 166 > 8 > 835-841

Genetic defects along the interleukin (IL)-12/interferon (IFN)−γ pathway have been found in patients with mendelian susceptibility to mycobacterial disease (MSMD) caused by live BCG vaccine or non-tuberculous Mycobacterium (NTM) species, highlighting the crucial role of this axis in human immunity to Mycobacterium. The aims of this study were to characterize healthy children presenting with cervical...

Evolution of a T-B- SCID into an Omenn syndrome phenotype following parainfluenza 3 virus infection

Ilan Dalal, Uri Tabori, Bela Bielorai, Hana Golan, more

Clinical Immunology > 2005 > 115 > 1 > 70-73

Mutations in both of the recombination activating genes (RAG)1 and RAG2 can lead to either T-B-severe combined immune deficiency (SCID) or Omenn syndrome (OS), two diseases presenting with totally different clinical and laboratory manifestations. The fact that the same mutations can cause either T-B- SCID or OS, even within the same family, lends credibility to the hypothesis that an additional factor...
