May antitransglutaminase levels predict severity of duodenal lesions in adults with celiac disease?

Background and Objective: Pediatric guidelines on celiac disease (CD) state that children with anti‐transglutaminase antibodies (TGAs) >×10 upper limit of normal (ULN) may avoid endos-copy and biopsy. We aimed to evaluate whether these criteria may be suitable for villous atrophy diagnosis in CD adults. Materials and Methods: We retrospectively enrolled patients with CD aged >18 years. TGAs were expressed as xULN. Duodenal lesions were classified as atrophic or non-atrophic according to Marsh‐Oberhuber. Fisher’s exact and t‐test were used for variables compari-son. Receiver operating characteristics (ROC) curve analysis was performed with estimation of area under the curve (AUC), sensitivity, specificity, and positive and negative predictive value (PPV/NPV). Results: One hundred and twenty‐one patients were recruited. Sixty patients (49.6%) had TGA >×10 ULN, and 93 (76.8%) had villous atrophy. The cut‐off of >×10 ULN had sensitivity = 53.7%, specificity = 64.3%, PPV = 83.3%, and NPV = 29.5% to predict atrophy. Therefore, considering pediatric criteria, in 50 (41.3%) patients, biopsy could have been avoided. Patient subgroup with atrophy had higher TGA levels despite being not significant (37.2 ± 15.3 vs. 8.0 ± 1.3 ULN, p = 0.06). In adults, a slightly better diagnostic performance was obtained using a cut‐off of TGA >×6.2 ULN (sensitivity = 57.1%, specificity = 65.6%, and AUC = 0.62). Conclusions: Despite our confirmation that villous atrophy is linked to high TGA levels, CD and atrophy diagnosis based only on serology is not reliable in adults

Severe anaemia after gastric biopsy in an infant with eosinophilic gastritis

Background: Eosinophilic gastrointestinal disorders (EGID) are characterized by eosinophilic inflammation and are subclassified according to the affected site(s) as eosinophilic esophagitis, eosinophilic gastritis, eosinophilic enteritis and eosinophilic colitis. Clinical presentation includes dyspeptic symptoms, vomiting, abdominal pain, diarrhoea and gastrointestinal bleeding. Peripheral eosinophilia is usually found but is not required for the diagnosis. The treatment is based on dietary elimination therapy, consisting of removal of common food triggers, most frequently cow's milk in infants. Corticosteroids are used as first line drug therapy in EG if dietary therapy fails to achieve an adequate clinical response or is impractical. Case presentation: A four month old infant was admitted for an episode of melena and hematemesis. An esophagogastroduodenoscopy showed haemorrhagic gastritis with ulcerative lesions and fibrin. A significant gastric bleeding was noted after the procedure. The gastric mucosa biopsies showed an eosinophilic infiltration. Conclusions: A clinically relevant anaemia is a quite rare complication in infants with eosinophilic gastritis and a biopsy may worsen bleeding, to a potentially severe level of low haemoglobin. In infants with low haemoglobin levels and suspect eosinophilic gastritis a watchful follow up after the biopsy should be considered, as well as the possibility of postponing the biopsy to reduce the bleeding risk

Liver fibrosis in primary intestinal lymphangiectasia: an undervalued topic

The relationship between primary intestinal lymphangiectasia (PIL) and liver fibrosis is an emerging topic with many obscure aspects due to the rarity of the disorder. A recent paper reported that a six-month lowfat diet improved liver fibrosis. We report the case of a 17-year-old girl affected by PIL whose hepatic fibrosis progressively worsened within one year, despite dietetic support. This and the previous case report describe extraordinary events, which do not allow clear-cut clinical aspects to be established. Nevertheless, both cases suggest that in patients with PIL, it is necessary to closely monitor liver morphology with in-depth investigations including not only ultrasonography, but also elastography

Late recovery with cyclosporine-A of an auto-immune sudden sensorineural hearing loss

Sensorineural hearing loss of immune-mediated origin may be present as a symptom in systemic autoimmune diseases or may occur as a primary disorder without other organ involvement (auto-immune inner ear disease). The diagnosis of auto-immune inner ear disease is still predicated on clinical features and to date specific diagnostic tests are not available. We report a case of right-sided sudden hearing loss in a female patient in which the clinical manifestations, in addition to ANA positivity and hypocomplementaemia allowed us to hypothesize an auto-immune inner ear disease. The immunosuppressive treatment with cyclosporine-A was capable of a recovery of the hearing that, however, occurred progressively with normalization of the hearing function after 1 year of treatment. cyclosporine-A could be proposed as a therapeutic option in case of auto-immune inner ear disease allowing the suspension of corticosteroids that, at high dose, expose patients to potentially serious adverse events

Studenti svantaggiati e fattori di promozione della resilienza

Molti studi evidenziano l’impatto che il contesto socio-economico e diverse caratteristiche degli studenti, quali il genere e il background migratorio, hanno sul raggiungimento di adeguate competenze in matematica. Questa situazione pone un problema di equità del sistema educativo e formativo: alcuni gruppi di giovani sono infatti svantaggiati in partenza per motivi indipendenti dal loro impegno nello studio. L’obiettivo del presente lavoro è valutare la presenza di fattori, su cui è possibile un intervento da parte degli insegnanti, che consentano a studenti svantaggiati di raggiungere risultati di eccellenza. Il contributo mira a identificare fattori associati non solo a una compensazione dello svantaggio legato alle condizioni di sfondo degli studenti, ma a una vera e propria inversione delle previsioni in termini di competenze raggiunte. I risultati mostrano l’impatto che l’appartenenza geografica, il background socio-economico-culturale delle scuole e delle famiglie e il genere, nella loro interazione, esercitano nel definire situazioni di forte svantaggio di partenza per gli studenti. Allo stesso tempo, gli esiti mettono in luce il ruolo protettivo giocato da alcune strategie d’insegnamento, dalle convinzioni di autoefficacia degli studenti e da altri fattori legati a specifiche situazioni di contesto.Many studies showed the impact that the socio-economic context and students’ characteristics, such as gender and migratory background, have on mathematical performance. This situation poses a problem of equity of the educational system: some groups of young people are in fact disadvantaged for reasons independent of their commitment to the study. The aim of this paper is to evaluate the presence of factors on which teachers can intervene, allowing disadvantaged students to achieve excellence. The contribution aims to identify associated factors not only to compensate for the disadvantage associated with student background conditions, but to a real reversal of predictions in terms of skills acquired. The results show the impact that geographic membership, the socio-economic-cultural background of schools and families and gender, in their interaction, exert in defining situations of major disadvantage for students. At the same time, there is evidence for the protective role played by some teaching strategies, student self-beliefs, and other factors related to specific background situations

Safety of measles, mumps, and rubella vaccine in egg allergy: in vivo and in vitro management

Background: Egg allergy is the second most prevalent form of food allergy in childhood. In spite of the evidence accumulated, inoculating egg allergy children with attenuated vaccines grown on chick embryo cell cultures, such as the measles, mumps, and rubella (MMR) vaccine, is regarded (erroneously) as potentially dangerous or even anaphylactogenic, by many. An issue perceived as particularly conflicting also by Health Professionals. Case presentation: A 15-year-old boy, with a history of severe egg allergy in early infancy, who was still sensitized to egg allergens, including baked egg, had never received MMR vaccination, in fear of possible anaphylaxis, in spite of the fact that this vaccination is mandatory in the first year of life, in Italy. Because of that, he was not allowed to attend school, longer, and was referred to us in order to assess the potential risk of MMR vaccination. Upon thorough allergologic workup, sensitization to MMR vaccine components was excluded by an in vivo approach, consisting in skin prick tests, intradermal tests, and subcutaneous injection test, corroborated by vaccine-specific B-lymphocyte proliferation assay, ex vivo. T-cell proliferation in response to MMR vaccine was also excluded. Eventually, the boy was inoculated with MMR vaccine and was readmitted to school. Conclusions: The diagnostic strategy adopted appears feasible and easy-to-perform and may be adopted in controversial cases (as the one reported), characterized by previous severe allergic reactions to egg. The B-lymphocyte proliferation assay we developed may represent a useful and reliable tool not only in research but also in clinical practice
