Differences in gene expression and cytokines levels between newly diagnosed and chronic pediatric immune thrombocytopenia (ITP)

ABSTRACT: Immune thrombocytopenia (ITP) is an autoimmune disease where platelets are destroyed prematurely. In the majority of children the disease resolves but in some it becomes chronic. To investigate whether the two forms of the disease are similar or separate entities we performed DNA microarray analysis of T-cells from newly diagnosed children and children with chronic ITP. We found complete separation of the expression files between the two forms of the disease. Furthermore, the gene expression of several cytokines differed between the two forms of the disease. This was also reflected in plasma with increased levels of IL-16 and TWEAK and lower levels of IL-4 in newly diagnosed compared with chronic ITP. Thus, our data indicate that the two forms of the disease may be separate entities.

Molecular basis for remission and tolerance induction in pediatric ITP

Project description:Children with newly diagnosed ITP that after 12 month enter remission, shows molecular separate entities. The molecular basis for remission and tolerance induction is characterized by gene transcriptional profiling Global gene expression profile in isolated T-cells from 6 children with newly diagnosed ITP and after 12 month when they enter remission

Acute ITP vs. Chronic ITP (Children)

Project description:Whole blood transcriptional profiling of pediatric idiopathic thrombocytopenic purpura (ITP) patients comparing self-limited acute ITP patients with chronic ITP patients or progression-to-chronic ITP patients. Patient samples were collected during 3 different disease states: 8 samples from acute ITP pts (within 6 months of dx, during active disease), 4 samples from progression-to-chronic ITP pts (within 6 months of dx), and 14 samples from chronic ITP (after 6 months of dx).

Gene expression in juvenile spondyloarthritis

Project description:Association of juvenile spondyloarthritis (jSpA) with the HLA-B27 genotype is well established, but there is little knowledge of other genetic factors with a role in disease development. The aim of the present study was to identify and confirm gene signatures and novel biomarkers in various cohorts of untreated and treated patients diagnosed with jSpA and other forms of juvenile idiopathic arthritis (JIA). DNA microarray gene expression was performed in 11 patients with jSpA and in four healthy controls, along with bioinformatics analysis of retrieved data (DAVID, GSEA, IPA). Total RNA was isolated from whole blood of 45 children with known HLA genotype and diagnosis of jSpA according to ILAR criteria, 11 children with oligo- and polyarticular forms of JIA, as well as 12 age and sex matched control participants without diagnosis of chronic inflammatory disease. Of those 11 patient and 4 controls were utilized in the microarrays experiments, while the rest were used in the follow-up qPCR analyses

Methylation profiling of human paediatric CD8+ T-cells in Crohn's Disease

Project description:CD8+ T-cell gene expression has been implicated in the pathogenesis of Inflammatory Bowel Diseases (IBD) and has been shown to correlate with disease outcome in adult patients. We aimed to explore DNA methylation in children newly diagnosed with Crohn's Disease and test for correlation with disease outcome.

Transcriptional profiling of human paediatric CD8+ T-cells in Inflammatory Bowel Diseases

Project description:Differences in CD8+ T-cell expression have previously been reported to correlate with disease outcome in adult patients diagnosed with Inflammatory Bowel Diseases (IBD). In addition, T-cell exhaustion was found to be associated with a milder disease course in adults. The purpose of this study was to test the prognostic value of the reported adult T-cell expression and exhaustion signatures in a cohort of children newly diagnosed with Crohn's disease (CD) and ulcerative colitis (UC). We also investigated the possibility of a paediatric specific prognostic expression signature.
