Late Endocrine Effects Despite Reduced Intensity Chemotherapy for Bone Marrow Transplantation in Children

Howell Jonathan , Myers Kasiani , Lane Adam , Wallace Gregory , Jodele Sonata , Rose Susan

Background: Bone marrow transplantation (BMT) is known to affect endocrine function, most commonly causing primary hypothyroidism and hypogonadism in children. Newer reduced intensity conditioning (RIC) uses less myeloablative chemotherapy and no irradiation. Our study goal was to evaluate endocrine effects at 1 year post BMT in pediatric patients who received RIC.Methods: Retrospective, IRB-approved chart review was performed on 121 patients (44 females...

Expression of Adam and Adamts Proteases Following Currative GnRHa Treatment for Cryptorchidism

Hadziselimovic Faruk , Verkauskas Gilvidas , Vincel Beata , Stadler Michael

Aim of the Study: ADAM/ADAMTS family members encode extracellular, multidomain proteolytic enzymes. Mutant Adamts16 mice display cryptorchidism and sterility. We hypothesize that gonadotropin-regulated ADAM/ADAMTS genes are involved in testicular development during mini-puberty.Patients and Methods: Testicular biopsies for histological and RNA-Sequencing analysis from bilateral cryptorchid boys were analyzed. RNA samples...

Genetic Markers Contribute to the PREDICTION of Response to GH in Severe but not Mild GH Deficiency

Stevens Adam , Murray Philip , Wojcik Jerome , Raelson John , Koledova Ekaterina , Chatelain Pierre , Clayton Peter

Background: Single nucleotide polymorphisms (SNPs) associated with the response to GH therapy have previously been identified in growth hormone deficient (GHD) children in the PREDICT long-term follow-up (LTFU) study (NCT00699855).Objective and hypotheses: To assess the effect of GHD severity on the predictive value of genetic markers of growth response.Method: We used pre-pubertal GHD children (peak GH <10 μg/l) from the ...

Random Forest Classification Predicts Response to Recombinant GH in GH Deficient Children Using Baseline Clinical Parameters and Genetic Markers

Stevens Adam , Murray Philip , Wojcik Jerome , Raelson John , Koledova Ekaterina , Chatelain Pierre , Clayton Peter

Background: Prediction of response to recombinant GH (r-GH) is currently based on regression modelling. This approach generates a prediction equation which can be applied to data from an individual child. However this method can underestimate the effect of inter-dependent variables. Random forest classification (RFC) is an alternative prediction method based on decision trees that is not sensitive to the relationships between variables.Objective and hypo...

Management of Graves' Disease

Cheetham Tim , Lane Laura , Wood Claire

Managing Graves' disease (GD) should be simple. Stop the immune system from targeting the TSH receptor and the disease is cured. Unfortunately this is not yet feasible in most young people and GD is not a trivial condition for those affected. There are significant advantages and disadvantages of all current treatments with no easy way forwards for many and the family's decisions will reflect their perceptions of medical, radiation and surgical risk. The fact that two o...

Graves Disease - Longer Term Impact on BMI

Kanaskar Suniva , Lane Laura , Ashokkumar Ashmethaa , Bignell Henry , Mohammed Zainab , Boelaert Kristien , Cheetham Timothy , Dias Renuka

Background: Graves’ Disease (GD) is the most common cause of hyperthyroidism in children and develops because of stimulation of the thyroid gland by TSH receptor auto-antibodies (TSHR Ab). An increased risk of obesity has been described in both adults and children following initiation of anti-thyroid drug (ATD) therapy but the longer term impact of GD and it’s treatment on physique in children is unclear.Aims:</strong...

The Effect of grB10-Deficiency in Zebrafish: A Translational Animal Model to Study Human Growth

De Leonibus Chiara , Barinaga-Rementeria Ramirez Irene , Hurlstone Adam , Clayton Peter , Stevens Adam

Background: GRB10 negatively regulates IGF1 signalling, influences growth and promoter polymorphisms are associated with GH response1. GRB10 knockout-mouse models display foetal overgrowth2, however, the mouse model has only partial similarity to human growth3. There is evidence that the zebrafish is an appropriate model to study growth4 and has the advantage of being easily genetically manipulated.<p class="abs...

Transient multiple pituitary hormone deficiency in critically ill pediatric patients

Dror Nitzan , Adam Dganit , Perl Liat , Eliakim Alon

Objective: Hospitalization in pediatric intensive care unit due to critical illness may be life threatening condition associated with severe acute physical stress and concomitant hormonal changes. Whether these changes represent an adaptive response or need to be treated is still not known.Methods: Pituitary hormones evaluation in four patients who were hospitalized in pediatric intensive care unit due to different sever...

Association between Prior Toxic Stressors and Development of T2DM in Adolescents

Adamidis Adam , Knee Alexander , Cobb Victoria , Conroy Rushika

Background: Low stress resilience in late adolescence and psychosocial traumatic events in adulthood have been linked to a higher risk of developing type 2 diabetes (T2DM) later on in life. However, limited data is available regarding whether prior stressors are related to the risk of developing T2DM in adolescence.Objective: We sought to determine the potential association between prior toxic stressors and T2DM in adolescence.Desi...

Transcriptomics and Machine Learning Methods Accurately Predict Diagnosis and Severity of Childhood Growth Hormone Deficiency

Murray Philip , Stevens Adam , Koledova Ekaterina , Chatelain Pierre , Clayton Peter

Background: The diagnosis of Growth Hormone Deficiency (GHD) involves the use of GH stimulation tests that require day case admission, multiple blood sampling and are associated with significant adverse effects.Aim: To assess the utility of gene expression (GE) profiling and candidate SNP analysis for the diagnosis of and classification of GHD.Method: Pre-pubertal treatment-naïve children with GHD (n=98) were enrolled from the...
