Evaluation of the nutritional status of children with type 1 diabetes and their healthy siblings.

BACKGROUND: Although there are studies evaluating the psychological adjustment of healthy children when their siblings have type 1 diabetes mellitus (T1DM), no study evaluating their nutritional status exists. Thus, this study aimed to determine the nutritional status of children with T1DM and their healthy siblings. MATERIAL AND METHODS: Data from a control group, healthy siblings, and patients who were followed and treated for T1D in the Paediatric Gastroenterology and Paediatric Endocrinology outpatient clinics of the Health Sciences University Gülhane Medical Faculty between November 2019 and November 2020 were analysed and compared. The groups were compared in terms of nutritional characteristics, daily macro and micronutrient intakes and classified according to their body mass index (BMI) Z-scores. RESULTS: The study population consisted of 29 children with T1DM (51.7% female, 48.3% male; age: 11.00 ±3.66 years), 36 healthy siblings of children with T1D (50% female, 50% male; age: 9.61 ±4.84 years), and a control group of 58 healthy children (51.7% female, 48.3% male; age: 10.68 ±3.01years).The BMI Z-score of 28.6%of healthy siblings and 25% of children with T1D was > 1 SD or overweight. All of the control group children were of normal weight. None of the children were obese; however, the overweight rate was significantly higher in the healthy siblings and diabetes groups compared to the control group (p = 0.012). Daily energy intake (%) was significantly higher in the control group than in the healthy siblings (p < 0.001). CONCLUSIONS: A quarter of the children with T1D over five years of age were overweight. In addition, healthy siblings were found to have higher BMI Z-scores than controls. This is the first study to evaluate the nutritional status of siblings of patients with T1D and will hopefully lead to more comprehensive studies that will also assess their daily exercise and physical activity.

The Relationship between Primary Duodenogastric Reflux and Helicobacter pylori Gastritis in Children.

BACKGROUND: Most studies of the relationship between duodenogastric reflux (DGR) and Helicobacter pylori have reported that the presence of DGR decreases H. pylori colonization, while H. pylori infection increases the frequency of DGR by impairing antroduodenal motility. The present study aimed to investigate the relationship between primary DGR and the prevalence of H. pylori in children, as well as the degree of colonization and the presence and severity of gastritis. METHODS: Included in the study were 410 patients between the ages of 2 and 18 years, referred to the pediatric gastroenterology clinic with complaints of dyspepsia, abdominal pain, and nausea/vomiting, who underwent upper gastrointestinal system endoscopic examination and stomach biopsy. The study group included 60 patients with DGR, while 350 non-DGR patients formed the control group. RESULTS: The mean age of patients with DGR was 15.7 ± 2.1 years, while the mean age of the control group was 14.2 ± 3.8 years (p = 0.02). Of those with DGR, 50 (83.3%) were girls, while in the control group, 215 (61.4%) were girls (p = 0.001). Of patients with DGR, 16 were H. pylori (+) (26.7%), while in the control group, 168 were H. pylori (+) (48%) (p = 0.002). There was no significant difference between the 2 groups with respect to H. pylori degree of colonization (p = 0.08). Gastritis was present in 56 (93.3%) patients in the DGR group and 322 (92%) patients in the control group (p = 0.72). A significant difference was found between the 2 groups in terms of gastritis severity (p = 0.01). CONCLUSIONS: The mean age of patients with DGR was significantly higher than that of patients without DGR, and DGR was found to be more common in girls. In patients with DGR, H. pylori prevalence was significantly lower than in those without DGR; however, no significant difference was found between the 2 groups with respect to the colonization degree.

Reliability of anti-tissue transglutaminase antibodies in children with malnutrition.

OBJECTIVES: Serological markers are used in the diagnosis of celiac disease. Among these, the most widely used are tissue transglutaminase antibodies (anti-TG2 antibodies). It has been suggested that the mechanisms that are set in motion by malnutrition cause the tight connections between enterocytes to expand, which allows gluten-derived peptides to pass through the epithelium. This causes the production of anti-TG2 antibodies without the presence of celiac disease. METHODS: The patients who were examined for malnutrition and had their anti-TG2 antibody levels measured at the same time, were accepted into the study. The patients who were investigated for suspected celiac disease, showed no signs of malnutrition, and had their anti-TG2 antibody levels measured were accepted into a control group. RESULTS: The study population consisted of 126 children with mild malnutrition (54.8% female, 7.44 ± 5.38 years); 89 children with moderate malnutrition (54.8% female, 7.62 ± 5.43 years), and a control group of 200 children (53.2% female, 7.72 ± 5.05 years). According to the results, anti-TG2 IgG levels were significantly higher among patients in the mild and moderate malnutrition groups compared to patients in the control group (p = .02 and p = .01, respectively). However, there was no significant difference between the mild and moderate malnutrition groups (p > .05). CONCLUSIONS: Malnutrition does not affect anti-TG2 IgA levels in children. However, anti-TG2 IgG levels increase in children suffering from malnutrition. When examining celiac disease, especially in people with a background IgA deficiency, doctors should consider whether malnutrition may be the cause of the increase in serum anti-TG2 IgG levels without celiac disease.

The Effect of Helicobacter pylori on the Presentation and Clinical Course of Coronavirus Disease 2019 Infection.

OBJECTIVES: Novel coronavirus 2019 (corona virus disease 2019 [COVID-19]) binds angiotensin-converting enzyme-2 (ACE-2) receptors to enter the cell. These receptors are widely expressed in the intestine, and COVID-19 may cause gastrointestinal symptoms via these receptors during the course of the disease. Helicobacter pylori is known to increase the expression of ACE-2 receptors in the gastrointestinal tract. The aim of this study was to investigate the effects of H pylori on the presentation and clinical course of COVID-19 infections. METHODS: This study was carried out from June 1 to July 20, 2020. Patients diagnosed with COVID-19 infections by PCR tests were included in the study. Antigen screening tests were performed on stool samples to determine the presence of H pylori. All patients were evaluated for manifestations of COVID-19 infection, severity of the course, hospitalized days because of the virus and outcome of the disease process. RESULTS: Of 108 COVID-19 positive patients evaluated, 31 with a mean age of 49.54 ±â€Š17.94 years were H pylori-positive (8 girls [25.8%]) and 77 with a mean age of 47.85 ±â€Š20.51 years; (31 girls [40.3%]) were H pylori-negative. Abdominal pain (19.4% vs 2.6%) and diarrhea (32.3% vs 9.1%) were significantly higher in patients with H pylori than those without (P = 0.007 and P = 0.006, respectively). There was no statistically significant difference between H pylori positivity and the number of hospitalized days, the severity of the course of COVID-19 infection, or the outcome of the disease (P > 0.05). CONCLUSION: Our results revealed that the findings of abdominal pain and diarrhea strongly correlated with the presence of H pylori in COVID-19 patients.

Efficacy of a novel sequential treatment regimen containing bismuth for Helicobacter pylori eradication in Turkish children.

BACKGROUND: Eradication rates of Helicobacter pylori (H pylori) with standard triple therapy are gradually decreasing all over the world, including in children, due to the development of strains resistant to antimicrobials. Sequential therapy can be used as an alternative method to increase eradication rates. MATERIALS AND METHODS: A total of 75 patients ≥ 8 years of age with H pylori gastritis were included in the study. According to Rome IV criteria, 38 patients had functional abdominal pain and dyspepsia, and 37 patients had alarm findings suggesting organic disease. Patients were treated with a novel sequential therapy consisting of the proton pump inhibitor (PPI)-lansoprazole (1 mg/kg/day, maximum 30 mg daily), amoxicillin (50 mg/kg/d in two doses, maximum 2 × 1000 mg) for 7 days followed by PPI-lansoprazole (1 mg/kg/d, maximum 30 mg daily), metronidazole (20 mg/kg/day in two doses, maximum 2 x 500 mg), tetracycline (50 mg/kg/d divided into four equal doses, maximum 4 x 500 mg), and bismuth subsalicylate (262 mg QID in patients ≤ 10 years of age, 524 mg QID in patients > 10 years of age in days 8-14). Eradication status was evaluated by H pylori stool antigen test 8 weeks after the completion of treatment. RESULTS: The mean age of the patients was 15.1 ± 2.4 years and 51 (68%) were female. No patient discontinued therapy due to side effects. All patients had antral gastritis (76.0%) or pangastritis (24.0%). The peptic ulcer rate was 6.6%. Eradication therapy was given to all patients with or without peptic ulcer. H pylori eradication was achieved in 69 (92.0%) patients and symptoms improved in 61 of those eradicated. CONCLUSIONS: As a first-line treatment for H pylori eradication in children, administering a novel sequential therapy including bismuth for 14 days provides a high rate of eradication.
