Associations of maternal type 1 diabetes with childhood adiposity and metabolic health in the offspring: a prospective cohort study.

Exposure to an intrauterine hyperglycaemic environment has been suggested to increase the offspring's later risk for being overweight or having metabolic abnormalities, but conclusive evidence for pregnancies affected by maternal type 1 diabetes is still lacking. This study aims to analyse the relationship between maternal type 1 diabetes and the offspring's metabolic health and investigate whether birthweight and/or changes in the offspring's metabolome are in the potential pathway. We analysed data from 610 and 2169 offspring having a first-degree relative with type 1 diabetes from the TEENDIAB and BABYDIAB/BABYDIET cohorts, respectively. Anthropometric and metabolic outcomes, assessed longitudinally at 0.3-18years of age, were compared between offspring of mothers with type 1 diabetes and offspring of non-diabetic mothers but with fathers or siblings with type 1 diabetes using mixed regression models. Non-targeted metabolomic measurements were carried out in 500 individuals from TEENDIAB and analysed with maternal type 1 diabetes and offspring overweight status. The offspring of mothers with type 1 diabetes had a higher BMI SD score (SDS) and an increased risk for being overweight than the offspring of non-diabetic mothers (e.g. OR for overweight status in TEENDIAB 2.40 [95% CI 1.41, 4.06]). Further, waist circumference SDS, fasting levels of glucose, insulin and C-peptide, and insulin resistance and abdominal obesity were significantly increased in the offspring of mothers with type 1 diabetes, even when adjusted for potential confounders and birthweight. Metabolite patterns related to androgenic steroids and branched-chain amino acids were found to be associated with offspring's overweight status, but no significant associations were observed between maternal type 1 diabetes and metabolite concentrations in the offspring. Maternal type 1 diabetes is associated with offspring's overweight status and metabolic health in later life, but this is unlikely to be caused by alterations in the offspring's metabolome.

Circulating MOTS-c levels are decreased in obese male children and adolescents and associated with insulin resistance.

A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted attention as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus (T2DM). MOTS-c profiles have not yet been reported in human obesity and T2DM. We aimed to determine circulating MOTS-c levels in obesity and explore the association between MOTS-c levels and various metabolic parameters. In this case-control study, 40 obese children and adolescents (27 males) and 57 controls (40 males) were recruited in the Hubei Province of China in 2017. Circulating MOTS-c levels were measured, clinical data (eg, glucose, insulin, and lipid profile) were recorded, and anthropometric measurements were performed. Finally, we investigated correlations between MOTS-c levels and related variables. MOTS-c levels were significantly decreased in the obese group compared with the control group (472.61 ±22.83 vs 561.64 ±19.19 ng/mL, P <.01). After classification by sex, MOTS-c levels were significantly decreased in obese male children and adolescents compared to their counterparts (465.26 ±24.53 vs 584.07 ±21.18 ng/mL, P <.001), while they were comparable between the obese and healthy female subjects (487.89 ±49.77 vs 508.85 ±38.76 ng/mL, P >.05). Further, MOTS-c levels were negatively correlated with body mass index (BMI), BMI SD score, waist circumference, waist-to-hip ratio, fasting insulin level, homeostasis model assessment of insulin resistance (HOMA-IR), and glycated hemoglobin (HbA1c) in the male cohort. Circulating MOTS-c levels were decreased in obese male children and adolescents and correlated with markers of insulin resistance and obesity.

Which predictors differentiate between obese children and adolescents with cardiometabolic complications and those with metabolically healthy obesity?

Childhood obesity and associated metabolic comorbidities is a major global health concern. Metabolically healthy obesity (MHO) may represent a subgroup of individuals in which excessive body fat accumulation does not lead to adverse metabolic effects. We aimed to determine the prevalence of MHO among obese Israeli children and adolescents and to find predictors for metabolically unhealthy obesity (MUO). In a retrospective study, demographic, anthropometric, lifestyle, and cardiometabolic data were retrieved from medical records of patients with a body mass index (BMI) >95th percentile aged 6 to 17.6 years, attending a tertiary pediatric obesity clinic between 2008 and 2015, with at least 1 year of follow-up. Participants were dichotomized as either MHO or MUO based on cardiometabolic risk factor clustering (blood pressure, serum lipids, and glucose). Multivariable logistic regression was used to determine predictors of MUO. Of the 230 children (median age 9.9 years) fulfilling study criteria, 48 (20.9%) were classified as MHO. Occurrence of MUO was associated with male gender, Arabic ethnicity, higher BMI-SD score, higher tri-ponderal mass index (TMI), and higher insulin resistance (IR) (presence of acanthosis nigricans and a higher level of homeostasis model assessment-IR [HOMA-IR]). Male gender (odds ratio [OR] 2.27, P = .033), presence of acanthosis nigricans at baseline (OR 2.35, P = .035), and a greater increase in BMI-SDS during follow-up (OR 2.82, P = .05) were the best predictors of MUO. The MHO phenotype was present in only 20.9% of obese Israeli children. MUO was significantly associated with male gender, with presence of acanthosis nigricans, and with a greater increase in BMI-SDS during follow-up.

Continuing rise of Type 2 diabetes incidence in children and young people in the UK.

AimsTo estimate the incidence of Type 2 diabetes in children aged <17 years, compare this with similar data 10 years ago, and characterize clinical features at diagnosis in the UK and Republic of Ireland.MethodsUsing the British Paediatric Surveillance Unit reporting framework, cases of Type 2 diabetes diagnosed in children aged <17 years between 1 April 2015 and 30 April 2016 were reported each month.ResultsA total of 106 cases were reported, giving a UK incidence of 0.72/100 000 (95% CI 0.58–0.88). Children from ethnic minorities had significantly higher incidence compared with white children (0.44/100 000) with rates of 2.92/100 000 and 1.67/100 000, in Asian and BACBB (black/African/Caribbean/black British) children respectively. Sixty‐seven percent were girls and 81% had a family history of Type 2 diabetes. The mean BMI sd score at diagnosis was 2.89 (2.88, girls; 2.92, boys); 81% were obese. Children of Asian ethnicity had a significantly lower BMI sd score compared with white children (P<0.001). There was a trend in increased incidence from 2005 to 2015, with a rate ratio of 1.35 (95% CI 0.99–1.84), although this was not statistically significant (P=0.062). There was statistical evidence of increased incidence among girls (P=0.03) and children of South‐Asian ethnicity (P=0.01) when comparing the 2005 and 2015 surveys.ConclusionsType 2 diabetes remains far less common than Type 1 diabetes in childhood in the UK, but the number of cases continues to rise, with significantly increased incidence among girls and South‐Asian children over a decade. Female gender, family history, non‐white ethnicity and obesity were found to be strongly associated with the condition.

The clinician factor: Personality characteristics of clinicians and their impact upon clinical outcomes in the management of children and adolescents with type 1 diabetes.

The purpose of this study was to estimate clinician qualities that influence metabolic outcomes in youth with type 1 diabetes. Data were gathered over two 3 month periods in a large tertiary diabetes center (1500 patients, 8 clinicians) from patients with type 1 diabetes who received continuous care from each clinician. Data included sex, age, diabetes duration, insulin regimen, body mass index (BMI), insulin dose and episodes of severe hypoglycemia. Clinician data included target blood glucose levels, target glycated hemoglobin (HbA1c), Diabetes Attitude Scale and Big 5 Personality Inventory Scale. Mean HbA1c per clinician was the primary outcome variable. The 8 clinicians saw a total of 464 patients during the first time period, and 603 in the second time period. Lowest to highest mean HbA1c per clinician varied by 0.7%. There were small but statistically significant differences between clinicians with their patients' age at diagnosis, duration of diabetes, age, gender, treatment type and BMI SD score. After controlling for these differences, the clinician characteristics that were associated with lower mean HbA1c were having no lower limit in target HbA1c and being self-reportedly "less agreeable." The impact of these clinician attitudinal traits was equivalent to the combined effects of patient characteristics and treatment type. There was a significant variation in metabolic outcomes between treating clinicians. After controlling for patient clinical differences, clinician mean HbA1c was associated with lower limit in target HbA1c and being "less agreeable." Clinicians who were more demanding and dogmatic appeared to have better outcomes.

Birth size, body composition, and adrenal androgens as determinants of bone mineral density in mid-childhood.

BackgroundBirth weight has an impact on adult bone mass. Higher birth weight is associated with greater bone mineral content (BMC) and children born small for gestational age (SGA) are at an increased risk for impaired accrual of bone mass. Our aim was to study whether the impact of birth size or early childhood growth on bone mass is visible already in mid-childhood.MethodsWe studied 49 children born large for gestational age (LGA), 56 children born appropriate for gestational age (AGA), and 23 children born SGA at 5.0-8.7 years of age. Body composition was assessed by whole-body dual-energy X-ray absorptiometry. Fasting blood samples and anthropometric data were collected.ResultsThe children born SGA had lower bone mineral density (BMD) Z-score (P<0.001) and age- and sex-adjusted BMD (P<0.005) than the LGA and AGA children. Adjusted BMC, muscle mass, and body fat percentage (%BF) did not differ between the study groups. Muscle mass, BMI SD score (SDS), %BF, and serum dehydroepiandrosterone sulfate (DHEAS) concentration were the strongest predictors of high BMD in mid-childhood.ConclusionSGA-born children had lower BMD in mid-childhood compared with AGA- and LGA-born ones. Muscle mass or BMI SDS, %BF, and DHEAS were significant predictors of childhood BMD.

Is early life exposure to polyomaviruses and herpesviruses associated with obesity indices and metabolic traits in childhood?

Evidence for an infectious origin of obesity is emerging. We explored whether common viruses were associated with obesity and metabolic traits. We used cross-sectional (n = 674) and prospective (n = 440) data from children participating at the 4 and 6 years of age follow-up in the Rhea birth cohort. Presence of IgG antibodies to ten polyomaviruses (BKPyV, JCPyV, KIPyV, WUPyV, HPyV6, HPyV7, TSPyV, MCPyV, HPyV9, and HPyV10) and four herpesviruses (EBV, CMV, HSV-1, and HSV-2) were measured at age 4. Body mass index, waist circumference, and skinfold thickness were measured at age 4 and 6. Data on serum lipids, leptin, and adiponectin were also available. Multivariable linear regression models were used to explore the associations. At 4 years of age, seroprevalence to polyomaviruses ranged from 21.0% for HPyV9 to 82.0% for HPyV10. Seroprevalence for EBV, CMV, HSV-1, and HSV-2 was 53.0%, 26.0%, 3.6%, and 1.5% respectively. BKPyV seropositivity was associated with lower BMI SD score at age 4 [-0.21 (95% CI: -0.39, -0.03)] and 6 [-0.27 (95% CI:-0.48, -0.05)], waist circumference at age 4 [-1.12 cm (95% CI: -2.10, -0.15)] and 6 [-1.73 cm (95% CI: -3.33, -0.12)], sum of four skinfolds [-2.97 mm (95% CI: -5.70, -0.24)], and leptin levels at age 4 [ratio of geometric means, 0.83 (95% CI: 0.70, 0.98)]. CMV seropositivity was associated with higher BMI SD score at age 4 [0.28 (95% CI: 0.11, 0.45)] and 6 [0.24 (95% CI: 0.03, 0.45)] and sum of four skinfolds at age 6 [4.75 mm (95% CI: 0.67, 8.83)]. Having "2-3 herpesviruses infections" (versus "0 herpesvirus infections") was associated with higher BMI SD score [0.32, (95% CI: 0.12, 0.53)], waist circumference [1.22 cm (95% CI: 0.13, 2.31)], and sum of four skinfolds [3.26 mm (95% CI: 0.18, 6.35)] at age 4. Polyomaviruses burden was not associated with outcomes. A higher herpesviruses burden and CMV seropositivity were associated with obesity traits in childhood.

Prevalence, clinical & biochemical correlates of non-alcoholic fatty liver disease in overweight adolescents.

Background & objectives:Non-alcoholic fatty liver disease (NAFLD) characterized by excessive accumulation of fat in the liver, which can progress to inflammation, and cirrhosis, has emerged as an important complication of obesity in adults as well as children. This study was undertaken to assess the prevalence of NAFLD and its correlation with clinical and biochemical parameters in overweight Indian adolescents.Methods:In this cross-sectional study, 218 overweight adolescents aged 10 to 16 yr and their parents were included. Measurements included anthropometry, ultrasonography to diagnose NAFLD, fasting glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lipids for adolescents and parents, and additional parameters of blood pressure, body fat percentage (BF%), fasting insulin, apolipoprotein C3, tumour necrosis factor-α and adiponectin for adolescents. The variables were compared between adolescents with and without NAFLD, and logistic regression analysis was performed.Results:Mean age and body mass index (BMI)SD score (SDS) were 11.9±1.6 yr and 2.3±1.1, respectively. NAFLD was seen in 62.5 per cent of the adolescents. The prevalence of NAFLD in the parents was similar among the adolescents with and without NAFLD, while BMI and waist circumference SDS, BF per cent, blood pressure (BP), ALT, AST, insulin and homeostatic model assessment of insulin resistance (HOMA-IR) were significantly higher in the adolescents with NAFLD. On multiple logistic regression, abdominal obesity, HOMA-IR and BF per cent were independently associated with NAFLD with odds ratios (95% confidence interval) of 2.77 (1.40-5.47), 2.21 (1.16-4.21) and 2.17 (1.12-4.22), respectively.Interpretation & conclusions:NAFLD was noted among nearly two-thirds of the overweight adolescents. An independent association was observed between abdominal obesity, HOMA-IR and body fat percentage and NAFLD in overweight adolescents.

Metabolic and immunological assessment of small-for-gestational-age children during one-year treatment with growth hormone: the clinical impact of apolipoproteins.

Children born small for gestational age (SGA) are at a higher risk for metabolic disorders later in life. In this study, we aimed to characterize young SGA children without catch-up growth and evaluate the effects of GH treatment on endocrinological, metabolic, and immunological parameters. Study design is a one-year single hospital-based study included prospective observation of SGA patients during 12 months of GH treatment. Clinical and laboratory profiles of SGA children at baseline were compared with controls born appropriate size for age. Twenty-six SGA children (median age, 3.4 years) and 26 control children (median age, 3.8 years) were enrolled. Anthropometric, hematologic, biochemical, immunological, and endocrinological parameters were assessed at baseline and 1, 3, 6, 9, and 12 months after the start of GH treatment. As a result, median height SD score (SDS) of SGA children increased by +0.42 with 12-month GH treatment. Body mass index SDS was lower in SGA children than in controls. Serum apolipoprotein A1 increased, whereas apolipoprotein B decreased during GH treatment. Serum leptin and resistin levels, which were lower in SGA children than in controls at baseline, did not change remarkably with GH treatment. Monocyte counts, which were lower in SGA patients at baseline, increased after GH treatment. Neutrophil counts significantly increased after GH treatment. Natural killer cell ratios, which were higher in SGA patients, decreased after GH treatment. In conclusion, there was no evidence suggesting metabolic abnormalities in SGA children. Serum apolipoprotein changes might predict the beneficial role of GH treatment in lowering cardiometabolic risk.

Real-Life Glycemic Control in Children with Type 2 Diabetes: A Population-Based Study

To characterize children and adolescents with type 2 diabetes mellitus (T2DM) insured by a large health maintenance organization, and to identify variables associated with treatment quality and disease outcome. Children and adolescents diagnosed with T2DM over a 9-year period were identified from the database of Clalit Health Services, a large health maintenance organization in Israel (1 213 362 members aged 0-18 years). Demographic, anthropometric, clinical, and laboratory data were analyzed. A total of 96 patients (47 males) met our inclusion criteria. The mean age at diagnosis of T2DM was 14.25 ± 2.51 years. At the time of diagnosis, the median hemoglobin A1c (HbA1c) level was 7.8%, and additional components of the metabolic syndrome were present in 14.9%-67.4% of the patients. At the end of the follow-up period (3.11 ± 1.75 years), >50% of the patients were being treated with insulin; the median HbA1c value was 7.97%, and 44.6% of the patients achieved the target HbA1c of <7.0%. On multivariate linear regression analysis, the variables found to predict worse glycemic control (ie, higher HbA1c) were a higher HbA1c at diagnosis, a higher body mass index SD score at diagnosis, fewer annual HbA1c tests, and Arabic ethnicity [F(4,81) = 7.139; P < .001; R2 = 0.271]. This population-based study of pediatric patients with T2DM demonstrates that reasonable glycemic control can be achieved in both community and outpatient hospital settings. Nevertheless, there is room for improvement in intervention programs to optimize outcomes and decrease the risk of complications.

Association of neck circumference and pulmonary function in children

BackgroundChildhood obesity leads to many complications including impaired respiratory function. There are various anthropometric parameters related to obesity. ObjectiveTo investigate the correlation between anthropometric indices and pulmonary function test results in children without asthma. MethodsChildren without any respiratory disorders were enrolled in this study. Anthropometric measurements, such as height, weight, neck circumference (NC), and waist circumference, were obtained from the enrollees and body mass index was calculated. Afterward, pulmonary function tests were performed using spirometry. ResultsA total of 178 children (106 boys, 59.5%) with a mean age of 9.7 years were included the study. NC was above the 90th percentile in 65 children. Importantly, pulmonary parameters, such as forced expiratory volume during the first second (FEV1) and the ratio of FEV1 to forced vital capacity (FVC), were lower in subjects with a large NC. Similarly, waist circumference was above the 90th percentile in 67 children, and FEV1/FVC was significantly lower in children with a large waist circumference. Moreover, there was a statistically significant negative correlation among FEV1, FEV1/FVC, and body mass index SD score. Also, multivariable linear regression analysis showed that an NC above the 90th percentile was associated with lower FEV1 and FEV1/FVC values. ConclusionWe identified NC as a novel anthropometric index that is strongly correlated with respiratory functions in children. Therefore, close monitoring of respiratory symptoms, particularly in children with obesity and a large NC, could help with early and prompt determination of respiratory complications of obesity.

Reductions in blood pressure during a community-based overweight and obesity treatment in children and adolescents with prehypertension and hypertension.

Due to the pandemic of childhood obesity and thus obesity-related hypertension, improvements in treatment availability are needed. Hence, we investigated whether reductions in blood pressure (BP) would occur in children with overweight and obesity exhibiting prehypertension/hypertension during a community-based overweight and obesity treatment program, and if changes in body mass index (BMI) are associated with changes in BP. The study included 663 children aged 3-18 years with a BMI ⩾85th percentile for sex and age that entered treatment from June 2012 to January 2015. Height, weight and BP were measured upon entry and every 3-6 months. BMI and BP s.d. scores (SDSs) were calculated according to sex and age, or sex, age and height. Prehypertension was defined as a BP SDS ⩾1.28 and <1.65. Hypertension was defined as a BP SDS ⩾1.65. Upon entry, 52% exhibited prehypertension (11.9%) or exhibited hypertension (40.1%). After 12 months (range: 3-29) of treatment, 29.3% of the children with prehypertension/hypertension were normotensive. Children with systolic prehypertension/hypertension upon entry reduced their systolic BP SDSs by 0.31 (95% confidence interval (CI): 0.70-0.83, P<0.0001). Children with diastolic prehypertension/hypertension upon entry reduced their diastolic BP SDSs by 0.78 (95% CI: 0.78-0.86, P<0.0001). BMI SDS changes were positively associated with BP SDS changes (P<0.0001). Nonetheless, some children reduced BP SDSs while increasing their BMI SDSs, and prehypertension/hypertension developed in 23.3% of the normotensive children despite reductions in BMI SDSs (P<0.0001). These results suggest that community-based overweight and obesity treatment can reduce BP, and thus may help improve treatment availability.

Testing the direction of effects between child body composition and restrictive feeding practices: results from a population-based cohort

Background: Parental restrictive feeding (i.e., limiting food intake of children) has been linked to childhood overweight. However, the directionality of the causal pathway remains unknown.Objective: The objectives of this study were to examine the bidirectional association of maternal restrictive feeding with children's weight and body composition across childhood and to explore a possible mediating role of maternal concern about child weight.Design: Data were available for 4689 mother-child dyads participating in Generation R, a prospective birth cohort in the Netherlands. At ages 4 and 10 y, restrictive feeding was assessed with the parent-reported Child Feeding Questionnaire, and children's body mass index (BMI) was measured. At age 6 y, fat mass index (FMI) and fat-free mass index (FFMI) were measured with dual-energy X-ray absorptiometry. Both directions of the relation between restriction and child body composition were examined with multivariable linear regression analyses and cross-lagged modeling. Mediation analyses were performed to examine concern about child weight (mother reported at child age of 10 y) as a potential mediator.Results: Higher child sex- and age-adjusted BMI SD scores (zBMI) at age 4 y predicted more restrictive feeding at age 10 y (B = 0.15; 95% CI: 0.11, 0.18). Both sex- and age-adjusted FMI SD scores (zFMI) and sex-and age-adjusted FFMI SD scores (zFFMI) at 6 y were also positively associated with restrictive feeding at 10 y. Maternal concern about child weight partially mediated these associations from child body composition to restrictive feeding (e.g., for zBMI at 4 y: Bindirect = 0.10; 95% CI: 0.07, 0.13). There was no temporal association from restrictive feeding at age 4 y to child zBMI at age 10 y after adjustment for baseline zBMI.Conclusions: The continued use of restrictive feeding practices at age 10 y appeared to be primarily a response of mothers to an unhealthy weight of their child rather than a cause of children's overweight. Guidelines discouraging restrictive feeding for preventing childhood overweight should therefore be reconsidered.

Longitudinal Trajectories of Metabolic Control From Childhood to Young Adulthood in Type 1 Diabetes From a Large German/Austrian Registry: A Group-Based Modeling Approach

Worsening of glycemic control in type 1 diabetes during puberty is a common observation. However, HbA1c remains stable or even improves for some youths. The aim is to identify distinct patterns of glycemic control in type 1 diabetes from childhood to young adulthood. A total of 6,433 patients with type 1 diabetes were selected from the prospective, multicenter diabetes patient registry Diabetes-Patienten-Verlaufsdokumentation (DPV) (follow-up from age 8 to 19 years, baseline diabetes duration ≥2 years, HbA1c aggregated per year of life). We used latent class growth modeling as the trajectory approach to determine distinct subgroups following a similar trajectory for HbA1c over time. Five distinct longitudinal trajectories of HbA1c were determined, comprising group 1 = 40%, group 2 = 27%, group 3 = 15%, group 4 = 13%, and group 5 = 5% of patients. Groups 1-3 indicated stable glycemic control at different HbA1c levels. At baseline, similar HbA1c was observed in group 1 and group 4, but HbA1c deteriorated in group 4 from age 8 to 19 years. Similar patterns were present in group 3 and group 5. We observed differences in self-monitoring of blood glucose, insulin therapy, daily insulin dose, physical activity, BMI SD score, body-height SD score, and migration background across all HbA1c trajectories (all P ≤ 0.001). No sex differences were present. Comparing groups with similar initial HbA1c but different patterns, groups with higher HbA1c increase were characterized by lower frequency of self-monitoring of blood glucose and physical activity and reduced height (all P < 0.01). Using a trajectory approach, we determined five distinct longitudinal patterns of glycemic control from childhood to early adulthood. Diabetes self-care, treatment differences, and demographics were related to different HbA1c courses.

Growth and BMI during the first 14 y of life in offspring from women with type 1 or type 2 diabetes mellitus.

Infants of women with pregestational diabetes are at risk for developing obesity in later life. This study aimed to identify subgroups at highest risk, by studying growth profiles of offspring from women with type 1 or 2 diabetes mellitus (ODM1, ODM2) until the age of 14 y. Information from infant welfare centers was received for 78 ODM1 and 44 ODM2. Mean BMI SD scores (SDS) (based on 1980 nation-wide references) and height SDS (based on 2009 references) were calculated and included in a random-effects model. Values were compared to the 2009 Dutch growth study. BMI SDS profiles differed between ODM1 and ODM2, with the highest mean BMI SDS profiles in ODM2. Other factors that affected growth profiles in these infants included the presence of maternal obesity, large for gestational age (LGA) at birth and in ODM2 a Dutch-Mediterranean origin. Offspring of women with diabetes have higher BMI SDS profiles than observed in the 2009 Dutch growth study, with the highest BMI SDS in ODM2 who are LGA at birth and have obese mothers. Preventive strategies for offspring adiposity may include pursuing lower prepregnancy maternal BMI, prevention of LGA at birth, and prevention of increased weight gain during childhood.

Growth Hormone Stimulation Tests in Children with Kabuki Syndrome

Background/Aims: Kabuki syndrome is a multiple congenital malformation syndrome with a variety of clinical features including short stature. The cause of this postnatal short stature remains unknown. Methods: Eighteen children with genetically proven Kabuki syndrome (8 boys and 10 girls; ages 3.3-9.9 years, with a mean of 6.7 years) who underwent growth hormone (GH) stimulation tests were evaluated in a prospective study. Two GH stimulation tests were conducted, including insulin-like growth factor I (IGF-I) and IGF-binding protein 3 (IGFBP-3) serum levels. GH stimulation peaks in relation to age, sex, height, body mass index (BMI), IGF-I, and IGFBP-3 SD scores (SDS) were analyzed. Results: Five of the 18 children (27.8%) were biochemically GH deficient. This was not correlated with BMI SDS. Of all patients, only 1 had an IGF-I below -2 SD and did not fulfill the GH deficiency criteria. The mean IGF-I level was below normal (-0.8 SD). All subjects had normal IGFBP-3 levels. Conclusions: The utility of performing GH stimulation tests on Kabuki syndrome children as an indication of GH status in short stature is questionable. IGF-I levels did correlate neither with the GH stimulation peak nor consequently with the diagnosis of GH deficiency.

Cortisol/cortisone ratio and matrix metalloproteinase-9 activity are associated with pediatric primary hypertension.

To identify novel biomarkers associated with pediatric primary hypertension. We recruited 350 participants (4-16 years). Anthropometric parameters and aldosterone, plasma renin activity, cortisol, cortisone, Homeostasis Model Assessment Insulin Resistance (HOMA-IR), high-sensitivity C-reactive protein, adiponectin, IL-6, plasminogen activator inhibitor type 1 levels and matrix metalloproteinase-9 and matrix metalloproteinase-2 (MMP-9 and MMP-2) activities were measured. Genomic DNA was isolated. Patients with altered glucose metabolism, severe obesity [BMI-SD score (BMI-SDS) > 2.5], renovascular disease, primary aldosteronism and apparent mineralocorticoid excess syndrome were excluded. In selected participants (n = 320), SBP was positively correlated with BMI-SDS (r = 0.382, P < 0.001), HOMA-IR (r = 0.211, P < 0.001), MMP-9 activity (r = 0.215, P < 0.001) and the cortisol/cortisone ratio (r = 0.231, P < 0.001). DBP showed similar correlations with these variables. No correlation was observed with aldosterone or plasma renin activity. Participants were categorized as hypertensive (n = 59) or nonhypertensive (n = 261). In the univariate analysis, hypertensive patients had higher BMI-SDS (P < 0.001), HOMA-IR (P < 0.001), high-sensitivity C-reactive protein (P < 0.001), MMP-9 activity (P < 0.001), plasminogen activator inhibitor type 1 (P < 0.001) and cortisol/cortisone ratio (P < 0.001) than nonhypertensive patients. Multiple regression analysis showed that the variables that remained associated with hypertension were higher BMI-SDS [odds ratio (OR) = 3.74; 95% confidence interval (CI) = 1.84-7.58], a higher cortisol/cortisone ratio (OR = 3.92; 95% CI = 1.98-7.71) and increased MMP-9 activity (OR = 4.23; 95% CI = 2.15-8.32). We report that MMP-9 activity and the cortisol/cortisone ratio were higher in pediatric primary hypertensive patients, and these associations were independent of the effect of obesity. The potential role of these novel biomarkers in predicting hypertension risk and blood pressure regulation warrants further investigation.
