Autosomal dominant hyper-IgE syndrome (HIES), also called Job syndrome, is a genetic disorder that affects the immune system.

Background:
Autosomal dominant hyper-IgE syndrome (HIES), also called Job syndrome, is a genetic disorder that affects the immune system. It can cause skin and lung infections and problems with blood vessels, connective tissues, and bones. People with HIES often have lupus-like disease or atopic dermatitis (skin rash). Researchers want to know if a drug approved to treat other immune system diseases (baricitinib) can help people with HIES.
Objective:
To test baricitinib in people with HIES with lupus-like disease or skin rash.
Eligibility:
People aged 12 years and older with HIES with lupus-like disease or skin rash.
Design:
Participants will have 5 clinic visits, 4 remote visits, and 2 phone visits in 9 months.
Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of the speed and pressure of blood flow through their body: Blood pressure cuffs will be placed on each arm and leg; electrodes will be placed on the wrists and a microphone on the chest.
The study has a 3-month lead-in period. Participants will not take the study drug during this time. They will continue with their usual medical care. They will have 2 phone calls with the study team.
Baricitinib is a tablet taken by mouth. Participants will take 1 or 2 tablets by mouth every day for 6 months. They will start with a low dose and may increase to a higher dose.
Blood and urine tests will be repeated during each study visit. Other tests may also be repeated during some visits. A skin sample may also be taken....

6. For individuals on glucocorticoids, the dose must be less than 10 mg daily and stable for the 30 days prior to Day 0.
7. For individuals on hydroxychloroquine or other antimalarials such as chloroquine or quinacrine, the dose must have been stable for 90 days prior to Day 0. The maximum allowed dose is hydroxychloroquine 400 mg/day or 6.5 mg/kg/day, whichever is greater. The maximum allowed dose for chloroquine phosphate is 500 mg daily, and for quinacrine is 100 mg daily.
8. Individuals may be on lipid-lowering medications if initiated at least 90 days prior to Day 0, and the dose must be stable for 30 days prior to Day 0.
9. Individuals of reproductive potential must agree to use at least one highly effective method of contraception when engaging in sexual activities that can result in pregnancy while on study drug. Acceptable methods of contraception include:
* Intrauterine device (IUD)
* Bilateral tubal ligation
* Abstinence
* Vasectomized partner
* Hormonal contraception used in combination with barrier method: progestogen containing (oral, intravaginal, transdermal) or progestogen-only (oral, injectable, implantable) starting 30 days prior to initiation of baricitinib
EXCLUSION CRITERIA:
An individual who meets any of the following criteria will be excluded from participation in this study:
1. Known history of hypersensitivity to baricitinib or other JAK inhibitors.
2. Current or recent use of any investigational drug/intervention (within 6 months or 5 half-lives, whichever is longer, prior to Day 0) except for COVID-19 vaccines or therapies that have been granted an FDA emergency authorization.
3. Scheduled to participate in another clinical study involving an investigational drug during the course of this study.
4. Use of systemic immunosuppressive or immune-modulating agents within 90 days prior to Day 0, except systemic steroids \<=10 mg of prednisone equivalent per day.
5. Current or prior treatment with rituximab in the 6 months prior to Day 0.
6. Current treatment with methotrexate, mycophenolate mofetil, other less common immunomodulatory drugs such as those falling into the class of disease-modifying antirheumatic drugs (DMARDs), belimumab, and other immunosuppressive biologics not otherwise specified herein. Participants previously on methotrexate, mycophenolate mofetil, azathioprine, tacrolimus, cyclosporine, or belimumab, other immunosuppressive biologics, or DMARDs should have been withdrawn from the drug for at least 90 days prior to Day 0.
