Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 month to 40 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult

Study population: We divided the patients with HIES into two groups, namely Autosomal-dominant Hyper-IgE Syndrome(AD-HIES) group and Autosomal-recessive Hyper-IgE Syndrome(AR-HIES) group. According to the different group, we need to do a variety of detection index, for example, gene mutations, B-lymphocyte subsets, protein expression et al.In addition, healthy control group is needed in the experiment.

Who may be able to join

  • Group 1 AD-HIES patients A.Patients with extremely high serum IgE levels, IgE>2000IU/ml; B.Patients diagnosis referred to the NIH, and NIH score>15; C.Patients must be confirmed with clinical manifestations of AD-HIES, namely:skin abscesses,pneumonias,distinctive facial appearance,dental abnormalities,minimal trauma fractures D.Patients must be confirmed with STAT3 gene mutations;
  • Group 2 AR-HIES patients A.Patients with extremely high serum IgE levels, IgE>2000IU/ml; B.Patients diagnosis referred to the NIH, and NIH score>15; C.Patients must be confirmed with clinical manifestations of AR-HIES, namely:pneumonias,eczema,Skin abscesses,mucocutaneous viral infections,malignancy D.Patients must be confirmed with Dedicator of cytokinesis protein 8(DOCK8) or Tyrosine Kinase 2(Tyk2) gene mutations;
  • Group 3 Healthy Control A.Healthy control aged 1-25 year at time of enrollment.

Who cannot join

  • Any subjects with serious conditions requiring treatment or hospitalization;
  • Any subjects with pregnancy;
  • Any subjects who have a history of bone marrow transplant,or have received treatment with chemotherapy or radiation;

About this study

Hyper IgE syndrome (HIES) is a rare and complex primary immunodeficiency that affects multiple systems. It is characterized by elevated Immunoglobulin E(IgE), recurrent skin and pulmonary infections and eczematoid dermatitis.Somatic manifestations include scoliosis, joint hyperextensibility, impaired shedding of deciduous teeth and facial dysmorphism.

The reason of extremely high level of serum IgE in the patients with HIES is unknown. Signal transducers and activators of transcription 3(STAT3) gene mutations can cause the STAT3/Janus kinase(STAT3/JAK) signal transduction pathway disorder, then can affect the B cell development.

It is reported that levels of extracellular signal cytokine and the prolonged half-life of IgE are not the causes of dramatically increased IgE levels in STAT3-HIES patients. According to our preliminary work, we found that the slight increase of IgE-secreting plasma cells could not explain the tremendously increased IgE level and that the key class switch recombination enzyme (AID) was up-regulated in STAT3-HIES patients. Intriguingly, we found that deregulation of immunoglobulin class switch recombination (CSR) in IgE secreting plasma cells in STAT3-HIES patients might play a key role in dramatically increased IgE levels.

Nuclear factor IL-3 regulated (NFIL3) is a newly discovered transcriptional factor. During STAT3-HIES IgE-secreting plasma cells differentiating, NFIL3 was significantly upregulated. The CSR of IgE was down-regulated in STAT3-deficiency mice as well as NFIL3-deficiency mice, however Interleukin-4(IL-4), a STAT3-independent cytokine, promotes NFIL3 expression by Signal transducers and activators of transcription 6(STAT6) dependent manner. Thus, we hypothesize that NFIL3 may play a key role in dramatically increased IgE levels in STAT3-HIES patients.

In-depth insight of the pathogenic role of NFIL3 within human STAT3-HIES has great significance in clarifying the pathogenesis of HIES and exploiting effective targeting interventions to improve clinical outcomes. Also, it can provide valuable clues for the clinical treatment of IgE-related diseases, such as parasite infection and malignant diseases.

Questions about this trial

What is this clinical trial studying?

An observational study of Job Syndrome, run by Shanghai Children's Medical Center.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 29 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Times of Pneumonia (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Aug 2014.
