Bariatric Surgery in Obese Adolescents

Dahlgren Jovanna

Background: Childhood obesity is a serious medical condition where excess body fat negatively affects a childÂ’s health. Although prevention is the primary step, there will be obese adolescents who benefit from bariatric surgery. There are four bariatric methods (all using laparoscopic technique): Adjustable Gastric Banding (AGB), Roux-en Y Gastric bypass (RYGB), sleeve gastrectomy and Bilio-Pancreatic Diversion (BPD). In Sweden we predominantly use RYGB as it improves eat...

A Decade of Clinical Experience in a Swedish University Centre Using Prediction Models to Optimize GH Treatment in Prepubertal Children

Dahlgren Jovanna

Background: The individual growth response on a certain GH dose is an indirect measurement of tissue responsiveness to GH. Several models of predicting the first year growth response on GH treatment are published and a clinical trial has been performed based on these algorithms. However, no clinical unit has evaluated the practical use of these prediction models on GH treatment.Objective and Hypotheses: To use prediction models in clinical practice to ch...

Serum Leptin, Adiponectin and Insulin-Like Growth Factor I During Infancy were Associated with Markers of Metabolic Syndrome at Six Years of Age

Dahlgren Jovanna , Kjellberg Emma , Roswall Josefine

Objective: Metabolic programming occurs during early life and nutritional factors are known to have long-lasting influences on metabolic health. We investigate associations between insulin-like growth factor I (IGF-I), leptin and adiponectin during infancy and metabolic markers in the same children at six years of age.Method: The Swedish longitudinal Halland Health and Growth birth cohort study is population-based, origi...

Oral Glucose Tolerance Test as a Routine Tool to Discriminate High Risk Individuals of Type 2 Diabetes in Child Obesity

Kintis Thomas , Marild Staffan , Dahlgren Jovanna

Background: It is debated whether oral glucose tolerance test (OGTT) should be routine in child obesity units to identify high risk individuals for impaired fasting glucose (IFG) or impaired glucose tolerance (IGT).Aims: To investigate the prevalence of some signs of metabolic syndrome in child obesity.Methods: All consecutive newly referred obese children (BMI>30) at a Swedish university unit were evaluated with fasting glucos...

Increased Adrenal and Testicular Androgen Concentrations Before Puberty and in Early Puberty Correlate to Adult Height Outcomes in Males with Silver-Russell Syndrome

Kvernebo-Sunnergren Kjersti , Ankarberg-Lindgren Carina , Dahlgren Jovanna

Background: In a previous study, we reported that adult height (AH) outcomes in growth hormone treated males with Silver-Russell syndrome (SRS) were negatively correlated with estradiol concentrations before start of puberty and in early puberty. Whether elevated estradiol concentrations originated from adrenal or testicular androgens is unclear. We aimed to describe androgen secretion patterns and investigate correlations between androgen concentrations and A...

Measurement of Estradiol and Testosterone in Umbilical Cord Blood by Gas Chromatography-Tandem Mass Spectrometry (GC-MS/MS); Comparisons with Radioimmunoassay (RIA)

Allvin Kerstin , Dahlgren Jovanna , Andersson Mats X , Ankarberg-Lindgren Carina

Background: We have previously shown radioimmunoassay (RIA) and gas chromatography-tandem mass spectrometry (GC-MS/MS) to be comparable when analyzing estradiol and testosterone concentrations in prepubertal and pubertal children. However, the reliability for steroid hormone determination with RIA in umbilical cord blood is not known. In general, older studies using RIA show higher values of testosterone, than more recent ones using MS/MS.Patients and me...

Correlations between Prepubertal and Pubertal Estrogen Levels and Final Height Out-Come in Growth Hormone (GH) Treated Boys with Silver Russell syndrome

Kvernebo-Sunnergren Kjersti , Ankarberg-Lindgren Carina , AEkesson Karin , Dahlgren Jovanna

Background: Children with Silver Russell syndrome (SRS) suffer from severe intrauterine growth retardation. During infancy, short stature and delayed bone maturation are common features. A majority of these children initially have a good growth response to GH treatment. A catch-up period of skeletal maturation is often seen in early puberty. Later in puberty poor height acceleration may be seen.Objective and hypothesis: The objective of this study was to...

Longitudinal Development of Adiponectin in Early Childhood and the Influence of Breastfeeding and Essential Fatty Acid Status

Roswall Josefine , Kjellberg Emma , Strandvik Birgitta , Dahlgren Jovanna

Background: Adiponectin is an adipokine related to insulin sensitivity. In adults and older children adiponectin correlates inversely to BMI, insulin resistance, and cardiovascular risk. Less is known about these relationships in early childhood.Objective and hypotheses: To explore the longitudinal development of adiponectin and correlations to early feeding patterns and serum essential fatty acids.Method: 324 term infants were fol...

Gender Differences in Sex Steroids and IGF1 at Birth and at 5 Years of Age

Allvin Kerstin , Karlsson Ann-Katrine , Ankarberg-Lindgren Carina , Dahlgren Jovanna

Background: Gender differences in sex steroids and IGF1 are well known from pubertal years into adulthood. Few studies report data from pre-school years.Objective and hypotheses: To study gender specific changes in sex steroids and IGF1 at birth and at 5 years of age and correlate these with auxological measurements. There are gender differences in IGF1 levels due to differences in sex steroids already at birth and during pre-school years.<p class="a...

Serum IGFI Concentration and Growth During Infancy Correlate to Polyunsaturated Fatty Acid Pattern

Dahlgren Jovanna , Kjellberg Emma , Strandvik Birgitta , Roswall Josefine

Background: IGF1 is important for fetal and infant growth and is influenced by nutrition. In young pigs, docosahexaenoic acid (DHA)-enriched food is associated with higher IGF1 levels but studies in human infants are lacking.Aims and objectives: To assess levels of polyunsaturated fatty acids (PUFA) relate to IGF1, birth size and growth during infancy.Methods: The setting was a population-based longitudinal cohort comprising 126 fu...
