Abstract

IMPORTANCE Early exposure to complex dietary proteins may increase the risk of type 1 diabetes in children with genetic disease susceptibility. There are no intact proteins in extensively hydrolyzed formulas. OBJECTIVE To test the hypothesis that weaning to an extensively hydrolyzed formula decreases the cumulative incidence of type 1 diabetes in young children. DESIGN, SETTING, AND PARTICIPANTS An international double-blind randomized clinical trial of 2159 infants with human leukocyte antigen-conferred disease susceptibility and a first-degree relative with type 1 diabetes recruited from May 2002 to January 2007 in 78 study centers in 15 countries; 1081 were randomized to be weaned to the extensively hydrolyzed casein formula and 1078 to a conventional formula. The follow-up of the participants ended on February 28, 2017. INTERVENTIONS The participants received either a casein hydrolysate or a conventional adapted cows milk formula supplemented with 20% of the casein hydrolysate. The minimum duration of study formula exposure was 60 days by 6 to 8 months of age. MAIN OUTCOMES AND MEASURES Primary outcome was type 1 diabetes diagnosed according to World Health Organization criteria. Secondary outcomes included age at diabetes diagnosis and safety (adverse events). RESULTS Among 2159 newborn infants (1021 female [47.3%]) who were randomized, 1744 (80.8%) completed the trial. The participants were observed for a median of 11.5 years (quartile [Q] 1-Q3, 10.2-12.8). The absolute risk of type 1 diabetes was 8.4% among those randomized to the casein hydrolysate (n = 91) vs 7.6% among those randomized to the conventional formula (n = 82) (difference, 0.8%[95% CI, -1.6% to 3.2%]). The hazard ratio for type 1 diabetes adjusted for human leukocyte antigen risk group, duration of breastfeeding, duration of study formula consumption, sex, and region while treating study center as a random effect was 1.1 (95% CI, 0.8 to 1.5; P = .46). The median age at diagnosis of type 1 diabetes was similar in the 2 groups (6.0 years [Q1-Q3, 3.1-8.9] vs 5.8 years [Q1-Q3, 2.6-9.1]; difference, 0.2 years [95% CI, -0.9 to 1.2]). Upper respiratory infections were the most common adverse event reported (frequency, 0.48 events/year in the hydrolysate group and 0.50 events/year in the control group). CONCLUSIONS AND RELEVANCE Among infants at risk for type 1 diabetes, weaning to a hydrolyzed formula compared with a conventional formula did not reduce the cumulative incidence of type 1 diabetes after median follow-up for 11.5 years. These findings do not support a need to revise the dietary recommendations for infants at risk for type 1 diabetes.

Abstract

Differences in breastfeeding, other milk feeding and complementary feeding patterns were evaluated in infants at increased genetic risk with and without maternal type 1 diabetes (T1D). The Trial to Reduce IDDM in the Genetically at Risk is an international nutritional primary prevention double-blinded randomized trial to test whether weaning to extensively hydrolyzed vs. intact cow's milk protein formula will decrease the development of T1D-associated autoantibodies and T1D. Infant diet was prospectively assessed at two visits and seven telephone interviews between birth and 8 months. Countries were grouped into seven regions: Australia, Canada, Northern Europe, Southern Europe, Central Europe I, Central Europe II and the United States. Newborn infants with a first-degree relative with T1D and increased human leukocyte antigen-conferred susceptibility to T1D were recruited. A lower proportion of infants born to mothers with than without T1D were breastfed until 6 months of age in all regions (range, 51% to 60% vs. 70% to 80%). Complementary feeding patterns differed more by region than by maternal T1D. In Northern Europe, a higher proportion of infants consumed vegetables and fruits daily compared with other regions. Consumption of meat was more frequent in all European regions, whereas cereal consumption was most frequent in Southern Europe, Canada and the United States. Maternal T1D status was associated with breastfeeding and other milk feeding patterns similarly across regions but was unrelated to the introduction of complementary foods. Infant feeding patterns differed significantly among regions and were largely inconsistent with current recommended guidelines.

Abstract

Objective: The recently observed increase in the incidence of type 1 diabetes mellitus (Type 1 DM) suggests a major role of environmental factors in the etiopathogenesis of the disease. The individual variation in cytochrome P[sub 450] IID6 may influence the individual susceptibility to environmentally linked diseases. We aimed to evaluate the prevalence of cytochrome P[sub 450] IID6 phenotypes in Hungarian children with Type 1 DM (n = 69) compared to healthy controls (n = 100). Methods: Debrisoquine was administered orally and debrisoquine hydroxylation phenotype was determined as a metabolic ratio of urinary recovered debrisoquine and 4-hydroxydebrisoquine. Results: Eight of the 100 healthy subjects (8%) and 15 of the 69 diabetic children (22%) (p < 0.05) had cytochrome P[sub 450] IID6 poor metabolizer phenotype (metabolic ratio ≥12.6). Conclusion: Cytochrome P[sub 450] IID6’s activity may play a role in the development of Type 1 DM. Copyright © 2004 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

17. HbA1c levels and erythrocyte transport functions in complication-free type 1 diabetic children and adolescents.

Author

Abstract

Higher erythrocyte sodium-lithium countertransport activity (SLC) is implicated in the development of diabetic nephropathy. Altered glucose homeostasis and genetic susceptibility are claimed to play a role in the elevation of SLC. We aimed to test whether metabolic control or the genetic variants of G protein beta 3 (Gb3) subunits determine SLC and other erythrocyte transport activities in complication-free stage of type 1 diabetes. A total of 96 complication-free type 1 diabetic children and adolescents were enrolled. SLC, Na+/K+-ATPase (NAK) and Ca2+-ATPase (CA) were measured by functional assays in erythrocytes. Gb3-C825T polymorphism was determined by PCR-RFLP. Results were related to HbA1c and were compared to those of 97 healthy controls. SLC activity was higher in diabetics (387±146 vs. 280±65 mmol/RBC · hour) and correlated with HbA1c levels (y=0.004x+6.42, r=0.33, n=96, p<0.01). NAK and CA activities were unaltered. The prevalence of 825T allele was similar in the patient and control groups (0.34 vs 0.37) and no differences in enzyme activities were observed between the 825T allele-positive and negative subjects. Although metabolic control correlated with SLC, other membrane functions were not affected. Therefore we hypothesize that the relationship between advanced glycation and SLC elevation is not causative. Rather, a genetic susceptibility for the coexistence of poor metabolic control and higher SLC is more likely. However, the presence of Gb3-C825T variant is not likely to be a risk factor for SLC-elevation and altered metabolic control diabetes. [ABSTRACT FROM AUTHOR]

Krikovszky D, Vsrhelyi B, Tóth-Heyn P, Körner A, Tulassay T, Madácsy L. Association between G-308 A polymorphism of the tumor necrosis factor-α gene and 24-hour ambulatory blood pressure values in type 1 diabetic adolescents. Clin Genet 2002: 62: 474–477. © Blackwell Munksgaard, 2002 Tumor necrosis factor-α (TNF-α) is an inflammatory cytokine, which also influences blood pressure (BP). The G-308 A polymorphism of the TNF-α gene is associated with altered TNF-α production. The prevalence of the TNF-α-308 A allele is reportedly higher among patients with type 1 diabetes mellitus (T1DM) than in the healthy population. In this study we investigated whether this genetic polymorphism might correlate with BP values in diabetic adolescents. Ambulatory BP monitoring (ABPM) was performed in 126 adolescents with T1DM (mean age: 14 ± 2.4 years). The TNF-α G-308 A genotype was determined by using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methodologies. ABPM results were related to healthy reference values and are given as standard deviation score (SDS). The prevalence of the -308 A allele was higher in diabetic adolescents than the Hungarian reference population (0.26 vs 0.14, p < 0.01). TNF-α genotype was associated both with systolic and diastolic BP values (p < 0.01 and p < 0.01, respectively). In patients with TNF-α-308 GG and -308 GA/AA genotypes, the 24-h systolic BP average values were 0.37 ± 1.33 and -0.38 ± 1.28 SDS, while 24-h diastolic BP average values were 0.09 ± 1.30 and -0.67 ± 1.31 SDS. Hence, the TNF-α-308 A allele carrier state appears to be associated with lower systolic and diastolic BP values. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Childhood interstitial lung disease (chILD) is a heterogeneous group of mostly chronic respiratory disorders. Assessment of health-related quality of life (HrQoL) in chILD has become increasingly important in clinical care and research. The aim of this study was to assess differences between patient-reported (self) and caregiver-reported (proxy) HrQoL scores., Methods: This study used data obtained from the chILD-EU Register. After inclusion (baseline), the patient's health status was followed up at predefined study visits. At each study visit, caregivers and patients were handed validated, age-specific HrQoL questionnaires. HrQoL data entered at baseline were used to compare self- and proxy-reported HrQoL scores. For the longitudinal analysis, we compared HrQoL scores between the baseline and the next follow-up visit., Results: No differences between patient- and caregiver-reported HrQoL scores were found for school functioning, chILD-specific questionnaire score, and physical health summary score. Self-reported HrQoL scores were higher for the subscales emotional functioning (77.4 vs. 70.7; p < .001), social functioning (81.9 vs. 76.2; p < .001), as well as psycho-social summary score (76.5 vs. 71.8; p < .001) and total score (74.7 vs. 70.8; <.001). The longitudinal analysis showed that a significant change in a patient-reported HrQoL score resulted in a significant change in a caregiver-reported HrQoL score after a mean time of 11.0 months (SD 9.4)., Conclusions: We found a good agreement between children- and caregiver-related HrQoL scores. In chILD, caregivers are able to sense changes in children's HrQoL scores over time and may be used as a proxy for children unable to complete HrQoL questionnaires., (© 2024 The Author(s).

Abstract

Background: Lysinuric protein intolerance (LPI) is a multi-organ metabolic disorder characterized by the imbalance in absorption and excretion of cationic amino acids like lysine, ornithine and arginine. Infants with LPI typically present with recurrent vomiting, poor growth, interstitial lung disease or renal impairment. The early onset of pulmonary alveolar proteinosis (PAP) has been reported to be associated with a severe form of LPI. Treatment of PAP most commonly consists of whole-lung lavage (WLL) and in autoimmune PAP, granulocyte-macrophage colony stimulating factor (GM-CSF) administration. Nevertheless, GM-CSF therapy in LPI-associated PAP has not been scientifically justified., Case Presentation: We describe the case of an 8-month-old infant presenting with respiratory failure due to LPI associated with PAP, who was twice treated with WLL; firstly, while on veno-venous ECMO assistance and then by the use of a selective bronchial blocker. After the two treatments with WLL, she was weaned from daytime respiratory support while on initially subcutaneous, then on inhaled GM-CSF therapy., Conclusions: This case supports the notion that GM-CSF therapy might be of benefit in patients with LPI-associated PAP. Further studies are needed to clarify the exact mechanism of GM-CSF in patients with LPI-associated PAP., (© 2024. The Author(s).)

Abstract

Background: No data on healthcare utilisation and associated costs for the many rare entities of children's interstitial lung diseases (chILD) exist. This paper portrays healthcare utilisation structures among individuals with chILD, provides a pan-European estimate of a 3-month interval per-capita costs and delineates crucial cost drivers., Methods: Based on longitudinal healthcare resource utilisation pattern of 445 children included in the Kids Lung Register diagnosed with chILD across 10 European countries, we delineated direct medical and non-medical costs of care per 3-month interval. Country-specific utilisation patterns were assessed with a children-tailored modification of the validated FIMA questionnaire and valued by German unit costs. Costs of care and their drivers were subsequently identified via gamma-distributed generalised linear regression models., Results: During the 3 months prior to inclusion into the registry (baseline), the rate of hospital admissions and inpatient days was high. Unadjusted direct medical per capita costs (€19 818) exceeded indirect (€1 907) and direct non-medical costs (€1 125) by far. Country-specific total costs ranged from €8 713 in Italy to €28 788 in Poland. Highest expenses were caused by the disease categories 'diffuse parenchymal lung disease (DPLD)-diffuse developmental disorders' (€45 536) and 'DPLD-unclear in the non-neonate' (€47 011). During a follow-up time of up to 5 years, direct medical costs dropped, whereas indirect costs and non-medical costs remained stable., Conclusions: This is the first prospective, longitudinal study analysing healthcare resource utilisation and costs for chILD across different European countries. Our results indicate that chILD is associated with high utilisation of healthcare services, placing a substantial economic burden on health systems., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Abstract

Paediatric organ transplantation today is considered and accepted and widely available therapy in children with end-stage organ failure. It is important to know that in childhood, diseases leading to end-stage organ failure differ from those in adults. Beside this, in children there are different surgical and paediatric challenges before and after transplantation (size differences of the patient and donor organ, special and paediatric infections, different pharmacokinetics and pharmacodynamics of immunosuppressive drugs, noncompliance). However, paediatric organ transplantation in the last decades became a success story of the Hungarian health care owing to several working groups in Hungary and outside the country.

Abstract

Background: Type 1 diabetes mellitus (T1DM) and celiac disease (CD) frequently occur together. Previous reports suggested that the (-308)A variant of the tumor necrosis factor-alpha (TNF-alpha) gene is associated either with T1DM or with CD. The aim of our study was to determine whether (-308)A and (-238)A allelic variants of the TNF-alpha gene might have any impact on the risk of CD in T1DM children., Methods: Three hundred and one T1DM children were enrolled to the study. The presence of CD was screened with IgA endomysial antibodies (EMA) test. Jejunal biopsy was performed to confirm CD. TNF-alpha-308 and -238 genetic variants were tested using the method of restriction fragment length polymorphism., Results: The prevalence of CD in the enrolled diabetic children was 6.3% (19 out of 301 children). The frequency of the (-308)A TNF-alpha variant was similar in the CD and the non-CD groups, exceeding the Hungarian healthy reference value. The number of (-238)A allele carriers was higher in the CD (4/19) than in the non-CD group (17/277) (p < 0.05)., Conclusions: Our study is limited by the small number of CD patients. On the basis of our findings, carriers of TNF (-308)A allele do not seem to have an increased risk for CD in T1DM. The association between TNF-alpha(-238)A allele carrier state and CD requires further investigation.

Abstract

Multiple immune mediators have been mentioned as playing a role in the pathomechanism of type1 DM. Interleukin (IL)-1beta, and tumor necrosis factor (TNF)-alpha play a central role in the autoimmune destruction of pancreatic beta-cells, whereas IL-6 inhibits TNF-alpha secretion, and may have some protecting effects. In our study, we aimed to investigate the association between these three cytokines' single nucleotide polymorphisms (IL-6 gene G(-174)C, TNF-alpha gene G(-308)A and IL-1beta gene C(3954)T polymorphisms) and age-at-onset of type 1 diabetes mellitus (T1DM) in 165 diabetic children (median age: 17 years). Polymorphisms were determined using the PCR-RFLP method. We found that the age-at-onset of T1DM was significantly different in patients with a different IL-6 genotype (median age-at-onset of T1DM was: 8, 6 and 4.5 years in children with the (-174)GG, GC and CC genotypes, respectively; p < 0.01). Adjusted for TNF-alpha and IL-1beta polymorphisms, patients with a IL-6 (-174)CC genotype have a 3.0-fold (95% CI: 1.2-7.1) increased risk of developing diabetes before the age of 6 years than (-174)G allele carrier patients. However, we found this association to be present only in patients who carried the TNF-alpha (-308)A or IL-1beta (3954)T allele, i.e. in patients with high TNF-alpha and high IL-1beta producer genotypes. We suppose that in the case of high TNF-alpha and IL-1beta producer genotypes, elevated proinflammatory cytokine levels result in a higher production of IL-6 in (-174)G allele carrier patients. This elevated IL-6 level may have a protective effect against the development of T1DM and may delay the destruction of pancreatic beta-cells.

Abstract

Background: Chemokines play an important role in the pathophysiology of asthma and allergy. Recently, polymorphisms in the gene regulatory region of monocyte chemoattractant protein 1 (MCP-1) and in the promoter region of RANTES have been found; these polymorphisms increase the expression of the chemokines., Objective: We investigated whether the presence of the polymorphisms was associated with atopy or asthma and whether these alleles influenced the severity of asthma in affected individuals., Methods: Three groups of subjects-160 children with asthma (disease severity being classified according to the Global Initiative for Asthma guidelines, modified for children), 151 children with nonasthmatic but allergic phenotype, and 303 children without allergic or asthmatic disorders-were screened with a PCR-based assay for genotyping., Results: The frequency of the -2518G polymorphism in the gene regulatory region of MCP-1 was significantly higher in asthmatic children than in controls (P <.001; odds ratio [OR] = 2.0 [1.4-2.6]) and nonasthmatic atopic children (P <.001; OR = 2.0 [1.4-2.9]). The MCP-1 G/G genotype correlated with asthma severity. In asthmatic children, the MCP-1 -2518G allele was also associated with an increased blood eosinophil level. The promoter polymorphisms in the RANTES gene did not have a detectable effect on the susceptibility to asthma or allergy or on the blood eosinophil count., Conclusion: In this cohort of children, there are associations between carrying G at -2518 of the MCP-1 gene regulatory region and the presence of asthma as well as between asthma severity and homozygosity for the G allele. In asthmatic children, the MCP-1 -2518G polymorphism correlated with increased eosinophil levels. This variant of MCP-1 might belong to the predictor gene set for asthma.

Abstract

Diabetic ketoacidosis is the most serious acute complication of insulin-dependent diabetes mellitus and the most frequent reason for hospital admission of diabetic children. The most frequent cause of death of these patients is also the diabetic ketoacidosis. The mortality rate of the disease has not changed since the seventies (1-2%). In this work, the data of 89 patients with diabetic ketoacidosis were analyzed. These patients were admitted to the 1. Department of Pediatrics of the Semmelweis University of Medicine between 1992-1997. The data (metabolic parameters, the causes of ketoacidosis and the length of hospital stay) of previously known diabetic children was compared with the data of previously unknown diabetic children. Our patients were divided in 2 groups: serious (n = 11), and mild-to-moderate (n = 48) acidosis. Their laboratory findings, their intravenous infusion-, and insulin demand and the length of their hospital stay were compared. The state of consciousness at their hospitalisation and the concomitant complications were also examined. Significant difference was found only in the duration of intravenous insulin administration (with the exception of pH and BE, of course). There was no relationship between the seriousness of the disease and the duration of hospital treatment. It is noteworthy that even the previously known diabetic children with the shortest hospitalization spent more than 7 days at the department.
