Assessment of respiratory function in infants and young children wearing face masks during the COVID-19 pandemic
Importance: Face masks have been associated with effective prevention of diffusion of viruses via droplets. However, the use of face masks among children, especially those aged younger than 3 years, is debated, and the US Centers for Disease Control and American Academy of Physicians recommend the use of face mask only among individuals aged 3 years or older.Objective: To examine whether the use of surgical facial masks among children is associated with episodes of oxygen desaturation or respiratory distress.Design, Setting, and Participants: This cohort study was conducted from May through June 2020 in a secondary-level hospital pediatric unit in Italy. Included participants were 47 healthy children divided by age (ie, group A, aged ≤24 months, and group B, aged >24 months to ≤144 months). Data were analyzed from May through June 2020.Interventions: All participants were monitored every 15 minutes for changes in respiratory parameters for the first 30 minutes while not wearing a surgical face mask and for the next 30 minutes while wearing a face mask. Children aged 24 months and older then participated in a walking test for 12 minutes.Main Outcomes and Measures: Changes in respiratory parameters during the use of surgical masks were evaluated.Results: Among 47 children, 22 children (46.8%) were aged 24 months or younger (ie, group A), with 11 boys (50.0%) and median (interquartile range [IQR]) age 12.5 (10.0-17.5) months, and 25 children (53.2%) were aged older than 24 months to 144 months or younger, with 13 boys (52.0%) and median (IQR) age 100.0 (72.0-120.0) months. During the first 60 minutes of evaluation in the 2 groups, there was no significant change in group A in median (IQR) partial pressure of end-tidal carbon dioxide (Petco2; 33.0 [32.0-34.0] mm Hg; P for Kruskal Wallis =.59), oxygen saturation (Sao2; 98.0% [97.0%-99.0%]; P for Kruskal Wallis =.61), pulse rate (PR; 130.0 [115.0-140.0] pulsations/min; P for Kruskal Wallis =.99), or respiratory rate (RR; 30.0 [28.0-33.0] breaths/min; P for Kruskal Wallis =.69) or for group B in median (IQR) Petco2 (36.0 [34.0-38.0] mm Hg; P for Kruskal Wallis =.97), Sao2 (98.0% [97.0%-98.0%]; P for Kruskal Wallis =.52), PR (96.0 [84.0-104.5] pulsations/min; P for Kruskal Wallis test=.48), or RR (22.0 [20.0-25.0] breaths/min; P for Kruskal Wallis =.55). After the group B walking test, compared with before the walking test, there was a significant increase in median (IQR) PR (96.0 [84.0-104.5] pulsations/min vs 105.0 [100.0-115.0] pulsations/min; P<.02) and RR (22.0 [20.0-25.0] breaths/min vs 26.0 [24.0-29.0] breaths/min; P<.05).Conclusions and Relevance: This cohort study among infants and young children in Italy found that the use of facial masks was not associated with significant changes in Sao2 or Petco2, including among children aged 24 months and younger
Neurotensin: any clue in pediatric celiac disease?
Background and aims: Neurotensin (NT) is a gut hormone secreted by specific endocrine cells scattered throughout the epithelial layer of the small intestine which has been identified as an important mediator in several gastrointestinal functions and disease conditions. Its potential involvement in celiac disease (CD) has been investigated, but there are conflicting findings. The aim of this study was to evaluate serum NT levels in children with CD at diagnosis comparing to a control group and to investigate if NT correlated in CD patients with symptoms, antibody response and intestinal mucosal damage.
Patients and methods: Children who underwent gastrointestinal endoscopy for CD or other clinical reasons were enrolled. Patients with CD diagnosed according to the latest ESPGHAN guidelines without biopsy were also recruited. Fasting serum samples were analyzed for NT levels using ELISA. Mann Whitney, Wilcoxon rank sum and Spearman’s rank tests were used for statistical analysis.
Results: 30 children (12M:18F, 1-16 years) were enrolled in this study. Of 25 patients who underwent endoscopy, 9 were CD patients, 13 were controls, 3 were excluded due to unspecific inflammation at duodenal biopsy. CD was diagnosed in 5 patients without biopsy.
NT median was higher in CD patients compared to controls (13.25 pg/ml vs 7.8 pg/ml; p = 0.02) (Mann-Whitney and Wilcoxon tests). No statistically significant correlation of NT with clinical, serological or histological data of CD was observed in this cohort.
Conclusion: At our knowledge, this is the first Italian study that evaluates NT in pediatric CD. Results show that NT is higher in the serum of CD children at diagnosis compared to controls; however, larger scale studies are required to validate these findings. Whether serum NT levels can be an adjunctive marker for pediatric CD remains currently elusive
Fasting Neurotensin Levels in Pediatric Celiac Disease Compared with a Control Cohort
Background and Aims. Neurotensin (NT) is a gut hormone secreted by specific endocrine cells scattered throughout the epithelial layer of the small intestine, which has been identified as an important mediator in several gastrointestinal functions and disease conditions. Its potential involvement in celiac disease (CD) has been investigated, but there are conflicting findings. The aim of this study was to evaluate serum NT levels in children with CD at diagnosis, compared to a control group, and to investigate whether NT correlated in CD patients with symptoms, antibody response, and intestinal mucosal damage. Materials and Methods. Children (1-16 years old) undergoing gastrointestinal endoscopy for CD or for other clinical reasons were included in this study. Patients with CD diagnosed according to the 2012 European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines without biopsy were also recruited. Fasting serum samples were analyzed for NT levels using ELISA. Logistic regression, Wilcoxon rank sum, and Spearman’s rank tests were used for statistical analysis. Results. Thirty children (18 females, 2.2-15.9 years old) were enrolled. Of 25 patients who underwent endoscopy, 9 were CD patients, 13 were controls, and 3 were excluded due to nonspecific inflammation at duodenal biopsy. CD was diagnosed in 5 patients without biopsy. NT median was higher in CD patients compared to controls (13.25 (IQR 9.4-17.5) pg/ml vs. 7.8 (IQR 7.6-10) pg/ml; p=0.02). No statistically significant association between NT and clinical, serological, or histological data of CD was observed in this CD cohort. Conclusions. To our knowledge, this is the first study that evaluates NT in CD children from Italy. Results show that NT is higher in the serum of CD children at diagnosis compared to controls. However, larger-scale studies are required to validate these findings. Whether serum NT levels can be an adjunctive marker for pediatric CD remains currently elusive
Cereal consumption among subjects with celiac disease: A snapshot for nutritional considerations
Background: To our knowledge no study has focused on the pattern of cereal-based products (CBP) consumption among people with celiac disease (CD). Our study aimed at evaluating the dietary intake of CBP among patients with CD and comparing it with a control population. Methods: Eighty-two volunteers with CD and 77 non-CD volunteers enrolled throughout Italy were asked to register their consumption of CBP on specific diaries for three days. Results: CD patients’ median three-day intake of biscuits and crackers was higher compared to controls (65.8 g vs. 22.7 g and 44.7 g vs. 10.6 g, p < 0.05 respectively, Mann–Whitney test). A significant difference was observed also comparing the two groups for median three-day bread consumption, with the CD group consuming less bread than controls (109.5 g vs. 150.7 g, p < 0.05, Mann–Whitney test). When assessing regional and gender-related CBP consumption patterns, significantly higher rice consumption was found among CD women from Northern Italy compared to CD women from Central and Southern Italy (p = 0.006 and p = 0.002 respectively, Fisher’s exact test). No other significant differences were observed. Conclusions: Our results provide a snapshot of the overall consumption of CBP among Italian subjects with CD. Altogether, these data show that, despite minor differences, dietary consumption of CBP among CD patients is similar to the general population
Autoimmune enteropathy in a 13-year-old celiac girl successfully treated with infliximab
Autoimmune enteropathy (AIE) is a rare cause of small bowel villous atrophy, characterized by malabsorption, unresponsiveness to dietary restriction, circulating autoantibodies to enterocytes, and an overall predisposition to autoimmunity. Albeit mainly regarded as a disease of early childhood, several adult-onset AIE cases have been identified. This report describes for the first time the life-threatening clinical presentation and the management of overlapping AIE in a compliant-to-diet young celiac girl. A 13-year-old celiac girl was admitted because of vomiting, weight loss, diarrhea, hypoproteinemia, and neurological disturbances such as head tremors, vertical nystagmus, and lower limb hyperesthesia. Before this, she had always been compliant on a strict gluten-free diet and her medical history was unremarkable. The diagnosis of AIE was established on histologic findings and on the presence of antienterocyte antibodies. She was initially treated with high-dose Methylprednisolone and Azathioprine. However, only Infliximab proved itself as a highly effective tool for achieving clinical remission and restoring small bowel villous architecture

Narrow band imaging combined with water immersion technique in the diagnosis of celiac disease
BACKGROUND:
The "multiple-biopsy" approach both in duodenum and bulb is the best strategy to confirm the diagnosis of celiac disease; however, this increases the invasiveness of the procedure itself and is time-consuming.
AIM:
To evaluate the diagnostic yield of a single biopsy guided by narrow-band imaging combined with water immersion technique in paediatric patients.
METHODS:
Prospective assessment of the diagnostic accuracy of narrow-band imaging/water immersion technique-driven biopsy approach versus standard protocol in suspected celiac disease.
RESULTS:
The experimental approach correctly diagnosed 35/40 children with celiac disease, with an overall diagnostic sensitivity of 87.5% (95% CI: 77.3-97.7). An altered pattern of narrow-band imaging/water immersion technique endoscopic visualization was significantly associated with villous atrophy at guided biopsy (Spearman Rho 0.637, p<0.001). Concordance of narrow-band imaging/water immersion technique endoscopic assessments was high between two operators (K: 0.884). The experimental protocol was highly timesaving compared to the standard protocol.
CONCLUSIONS:
An altered narrow-band imaging/water immersion technique pattern coupled with high anti-transglutaminase antibodies could allow a single guided biopsy to diagnose celiac disease. When no altered mucosal pattern is visible even by narrow-band imaging/water immersion technique, multiple bulbar and duodenal biopsies should be obtaine
