Hyper IgE Syndrome (Job Syndrome): Symptoms, Diagnosis, and Treatment
Introduction
Hyper IgE syndrome, also known as Job syndrome, is a rare primary immunodeficiency disorder that affects the immune system. First identified in the 1960s, this condition is characterized by elevated levels of immunoglobulin E (IgE) in the blood, recurrent skin and lung infections, and other immune-related complications. The syndrome is named after the biblical figure Job, who endured chronic boils, a symptom often seen in patients with this condition. Although rare, understanding Hyper IgE syndrome is essential for early diagnosis and effective management.
This article provides a comprehensive overview of Hyper IgE syndrome, covering risk factors, symptoms, diagnostic tests, treatment options, and steps patients can take at home to manage their symptoms. By simplifying complex medical information, we aim to empower patients and their families to make informed health decisions.
Definition of Hyper IgE Syndrome (Job Syndrome)
Hyper IgE syndrome (Job syndrome) is a rare immunodeficiency disorder characterized by elevated IgE levels, with symptoms including recurrent infections, eczema, and lung complications. Diagnosis involves specific tests, treatment includes medications and procedures, and management often requires lifestyle adjustments.
Description of Hyper IgE Syndrome (Job Syndrome)
Hyper IgE syndrome (HIES), or Job syndrome, is a rare genetic disorder that impairs the immune system, making it difficult to fight infections. The hallmark of this condition is abnormally high levels of immunoglobulin E (IgE), an antibody involved in allergic reactions. Patients with HIES often experience recurrent skin abscesses, lung infections, and eczema, with symptoms typically beginning in infancy or early childhood and persisting throughout life.
As the condition progresses, additional complications such as lung damage, bone abnormalities, and dental issues may arise. Some patients may also experience joint problems and scoliosis (curvature of the spine). Symptom severity can vary significantly, even among individuals within the same family.
Hyper IgE syndrome is extremely rare, affecting approximately 1 in 1 million people. It affects males and females equally and can be inherited in either an autosomal dominant or autosomal recessive pattern, depending on the genetic mutation involved. Early diagnosis and treatment are crucial to prevent long-term complications and improve quality of life.
Risk Factors for Developing Hyper IgE Syndrome (Job Syndrome)
Lifestyle Risk Factors
Unlike many health conditions, lifestyle factors such as diet, exercise, or smoking do not directly cause Hyper IgE syndrome. However, certain lifestyle choices can exacerbate symptoms or increase the risk of complications. For instance, exposure to environmental allergens like dust, pollen, or pet dander can worsen eczema and other skin conditions in HIES patients. Additionally, poor hygiene or living in polluted environments may heighten the risk of infections, particularly lung infections, which are common in individuals with this condition.
Medical Risk Factors
Patients with a history of recurrent infections, especially skin abscesses, pneumonia, or other lung infections, may be at higher risk for Hyper IgE syndrome. Those diagnosed with other immune system disorders or with a family history of immunodeficiency conditions should also be aware of the potential for HIES. In some cases, patients may be misdiagnosed with more common conditions like eczema or asthma before the underlying immune deficiency is identified.
Genetic and Age-Related Risk Factors
Hyper IgE syndrome is primarily a genetic disorder, inherited from one or both parents. There are two main types: autosomal dominant and autosomal recessive. The autosomal dominant form is caused by mutations in the STAT3 gene, while the autosomal recessive form is linked to mutations in other genes, such as DOCK8. Individuals with a family history of these genetic mutations are at higher risk of developing the condition.
Age is another important factor. Symptoms often appear in infancy or early childhood, though the condition may go undiagnosed until later in life. Early recognition of symptoms and genetic testing can help identify the condition before serious complications arise.
Clinical Manifestations of Hyper IgE Syndrome (Job Syndrome)
Recurrent Infections (100%)
Recurrent infections are a hallmark of Hyper IgE syndrome, affecting nearly all patients. These infections are often bacterial or fungal, commonly involving the skin, lungs, and sinuses. Due to abnormal immune signaling, patients struggle to fight off pathogens, leading to frequent skin abscesses, pneumonia, and ear infections. These infections typically begin in early childhood and persist throughout life, often requiring long-term antibiotic therapy.
Eczema (100%)
Eczema, or atopic dermatitis, affects all patients with Hyper IgE syndrome. This chronic skin condition presents as red, itchy, and inflamed patches. Elevated IgE levels contribute to an overactive immune response, causing inflammation and skin barrier dysfunction. Eczema in HIES patients can be severe and resistant to standard treatments, often requiring specialized care. The condition may worsen during infection flare-ups or periods of stress.
Elevated Serum IgE Levels (100%)
One defining feature of Hyper IgE syndrome is significantly elevated IgE levels in the blood. IgE is an antibody involved in allergic reactions. In HIES patients, IgE levels can be thousands of times higher than normal, contributing to allergic-like symptoms such as eczema and allergic rhinitis. Elevated IgE levels are present from early childhood and persist throughout life, serving as a critical diagnostic marker.
Skeletal Abnormalities (70%)
About 70% of patients with Hyper IgE syndrome develop skeletal abnormalities, including scoliosis, joint hyperextensibility, and fractures from minimal trauma. These issues are thought to stem from abnormal connective tissue development, influenced by the genetic mutations associated with the syndrome. Skeletal problems may worsen with age, leading to chronic pain and mobility issues.
Dental Abnormalities (70%)
Dental abnormalities, particularly retained primary teeth (failure of baby teeth to fall out), occur in about 70% of HIES patients. This is due to delayed tooth shedding, likely related to abnormal immune and connective tissue functions. As a result, adult teeth may become impacted or misaligned, requiring dental intervention. Regular dental check-ups are essential for managing these issues.
Lung Infections (60%)
Recurrent lung infections, including pneumonia, affect around 60% of HIES patients. These infections are often caused by bacteria like Staphylococcus aureus and fungi such as Aspergillus. The immune system’s inability to clear infections leads to chronic lung damage, resulting in bronchiectasis (permanent airway widening) and scarring. Early, aggressive treatment is crucial to prevent long-term complications.
Abscess Formation (60%)
Abscesses, or pus-filled pockets, form in about 60% of HIES patients. These abscesses can occur in the skin, lungs, and other organs, typically caused by bacterial infections like Staphylococcus aureus. The immune system’s impaired ability to fight infections leads to abscess formation, often requiring drainage and antibiotics. Skin abscesses are particularly common and may recur frequently.
Allergic Rhinitis (50%)
Allergic rhinitis, or hay fever, affects about 50% of HIES patients. Symptoms include sneezing, nasal congestion, runny nose, and itchy eyes. Elevated IgE levels contribute to an exaggerated allergic response to environmental allergens like pollen, dust mites, and pet dander. Managing allergic rhinitis often requires antihistamines, nasal corticosteroids, and allergen avoidance.
Failure to Thrive (30%)
Failure to thrive, or poor growth and weight gain, occurs in about 30% of children with Hyper IgE syndrome. This may result from chronic infections, nutrient malabsorption, and increased energy demands due to constant immune activity. Nutritional support and close monitoring of growth and development are essential to ensure children reach appropriate milestones.
Chronic Sinusitis (30%)
Chronic sinusitis, or long-term sinus inflammation, affects around 30% of HIES patients. Recurrent bacterial and fungal infections of the sinuses, which the immune system struggles to clear, are common. Symptoms include nasal congestion, facial pain, and postnasal drip. Chronic sinusitis can lead to complications like nasal polyps and may require surgical intervention in severe cases.

Health Conditions with Similar Symptoms to Hyper IgE Syndrome (Job Syndrome)
Wiskott-Aldrich Syndrome
Wiskott-Aldrich syndrome (WAS) is a rare genetic disorder that affects both the immune system and blood clotting. It is caused by mutations in the WAS gene, leading to immune cell dysfunction and low platelet counts. Individuals with WAS are more susceptible to infections, eczema, and bleeding problems due to their reduced platelet levels.
How to Know if You Might Have Wiskott-Aldrich Syndrome vs. Hyper IgE Syndrome (Job Syndrome)
Both Wiskott-Aldrich syndrome and Hyper IgE syndrome can cause recurrent infections and eczema-like rashes. However, WAS is more likely to result in bleeding issues, such as easy bruising or prolonged bleeding, which are uncommon in Hyper IgE syndrome. WAS patients often have very low platelet counts, detectable through a blood test, while Hyper IgE syndrome is characterized by extremely high IgE levels. If you experience frequent nosebleeds, blood in your stool, or other bleeding problems along with infections, WAS may be more likely than Hyper IgE syndrome.
Chronic Granulomatous Disease
Chronic granulomatous disease (CGD) is a genetic disorder that impairs the ability of certain immune cells to kill bacteria and fungi, leading to frequent, severe infections, particularly in the lungs, skin, and lymph nodes. People with CGD are also prone to developing granulomas, which are clusters of immune cells formed in response to chronic inflammation.
How to Know if You Might Have Chronic Granulomatous Disease vs. Hyper IgE Syndrome (Job Syndrome)
Both CGD and Hyper IgE syndrome can cause recurrent bacterial and fungal infections, especially in the lungs and skin. However, CGD is more likely to cause granulomas, which can obstruct the digestive or urinary tracts, a symptom not typically seen in Hyper IgE syndrome. CGD also often presents with abscesses in the liver, lungs, or bones, which are less common in Hyper IgE syndrome. A nitroblue tetrazolium (NBT) test or dihydrorhodamine (DHR) flow cytometry test can diagnose CGD by evaluating neutrophil function. If these tests show defective neutrophil function, CGD is more likely than Hyper IgE syndrome.
Hyper-IgM Syndrome
Hyper-IgM syndrome is a group of genetic disorders that affect the immune system’s ability to produce certain antibodies. People with this condition have normal or elevated IgM levels but low levels of other antibodies, such as IgG, IgA, and IgE, making them more vulnerable to infections.
How to Know if You Might Have Hyper-IgM Syndrome vs. Hyper IgE Syndrome (Job Syndrome)
Both Hyper-IgM syndrome and Hyper IgE syndrome can cause recurrent infections, particularly in the lungs and sinuses. However, Hyper-IgM syndrome typically involves low IgG and IgA levels, while Hyper IgE syndrome is marked by extremely high IgE levels. A blood test measuring antibody levels can help distinguish between the two. Additionally, Hyper-IgM syndrome is more likely to cause severe infections with opportunistic organisms like *Pneumocystis jirovecii*, which is less common in Hyper IgE syndrome. If your blood test shows low IgG and IgA but normal or high IgM, Hyper-IgM syndrome may be the cause of your symptoms.
Common Variable Immunodeficiency (CVID)
Common variable immunodeficiency (CVID) is a disorder that impairs the immune system’s ability to produce antibodies, leading to frequent infections. People with CVID often experience recurrent respiratory infections, gastrointestinal issues, and an increased risk of autoimmune diseases.
How to Know if You Might Have Common Variable Immunodeficiency vs. Hyper IgE Syndrome (Job Syndrome)
Both CVID and Hyper IgE syndrome can cause recurrent respiratory infections, such as pneumonia or sinusitis. However, CVID is more likely to cause gastrointestinal problems, such as chronic diarrhea or malabsorption, which are not typical in Hyper IgE syndrome. Additionally, CVID patients often have low levels of all antibody types (IgG, IgA, and IgM), while Hyper IgE syndrome is marked by extremely high IgE levels. A blood test measuring antibody levels can help differentiate between the two conditions. If you have low levels of multiple antibodies and frequent gastrointestinal symptoms, CVID may be more likely than Hyper IgE syndrome.
Atopic Dermatitis
Atopic dermatitis, or eczema, is a chronic skin condition that causes dry, itchy, and inflamed skin. It is often associated with allergies and asthma and can flare up in response to environmental triggers like allergens or stress.
How to Know if You Might Have Atopic Dermatitis vs. Hyper IgE Syndrome (Job Syndrome)
Both atopic dermatitis and Hyper IgE syndrome can cause eczema-like rashes. However, atopic dermatitis is usually limited to the skin and does not cause the recurrent infections seen in Hyper IgE syndrome. People with atopic dermatitis may also have a history of allergies or asthma, which are not typically associated with Hyper IgE syndrome. A skin biopsy or allergy testing may diagnose atopic dermatitis, while blood tests showing extremely high IgE levels are more indicative of Hyper IgE syndrome. If your symptoms are primarily skin-related without frequent infections, atopic dermatitis may be the more likely diagnosis.
Autoimmune Lymphoproliferative Syndrome (ALPS)
Autoimmune lymphoproliferative syndrome (ALPS) is a rare genetic disorder that affects the immune system’s ability to regulate itself, leading to an overproduction of lymphocytes and an increased risk of autoimmune diseases, where the immune system attacks the body’s tissues.
How to Know if You Might Have Autoimmune Lymphoproliferative Syndrome vs. Hyper IgE Syndrome (Job Syndrome)
Both ALPS and Hyper IgE syndrome can cause immune system dysfunction, but ALPS symptoms are more focused on autoimmune issues, such as anemia, low platelet counts, or enlarged lymph nodes and spleen, which are not typical in Hyper IgE syndrome. Additionally, ALPS patients may develop autoimmune conditions like lupus or autoimmune hepatitis, which are not associated with Hyper IgE syndrome. A blood test showing elevated lymphocytes and autoimmune markers can help distinguish ALPS from Hyper IgE syndrome. If you have autoimmune disease symptoms along with immune dysfunction, ALPS may be more likely than Hyper IgE syndrome.
Severe Combined Immunodeficiency (SCID)
Severe combined immunodeficiency (SCID) is a group of genetic disorders that cause a severe deficiency in both T cells and B cells, which are critical components of the immune system. People with SCID are highly susceptible to infections and often develop life-threatening infections in infancy.
How to Know if You Might Have Severe Combined Immunodeficiency vs. Hyper IgE Syndrome (Job Syndrome)
Both SCID and Hyper IgE syndrome can cause recurrent infections, but SCID typically presents in infancy with severe, life-threatening infections, while Hyper IgE syndrome may not become apparent until later in childhood. SCID affects both T cells and B cells, leading to a broader range of immune deficiencies, while Hyper IgE syndrome primarily affects IgE antibody production. A blood test showing very low T and B cell levels can help diagnose SCID, while extremely high IgE levels are more indicative of Hyper IgE syndrome. If you or your child has had severe infections early in life, SCID may be more likely than Hyper IgE syndrome.
Cystic Fibrosis
Cystic fibrosis (CF) is a genetic disorder that affects the lungs and digestive system. It causes thick, sticky mucus to build up in the lungs, leading to frequent respiratory infections, and can also cause digestive problems due to blockages in the pancreas.
How to Know if You Might Have Cystic Fibrosis vs. Hyper IgE Syndrome (Job Syndrome)
Both cystic fibrosis and Hyper IgE syndrome can cause recurrent lung infections, but cystic fibrosis is more likely to cause digestive problems, such as difficulty gaining weight or frequent greasy stools, which are not typical in Hyper IgE syndrome. People with cystic fibrosis often have a chronic cough and produce thick mucus, while those with Hyper IgE syndrome may have more skin-related symptoms, such as eczema. A sweat test, which measures the amount of salt in your sweat, can help diagnose cystic fibrosis, while blood tests showing high IgE levels are more indicative of Hyper IgE syndrome. If you have both lung and digestive symptoms, cystic fibrosis may be more likely than Hyper IgE syndrome.
Primary Immunodeficiency Disorders
Primary immunodeficiency disorders (PIDs) are a group of genetic conditions that affect the immune system’s ability to fight infections. People with PIDs are more susceptible to infections, autoimmune diseases, and certain cancers.
How to Know if You Might Have Primary Immunodeficiency Disorders vs. Hyper IgE Syndrome (Job Syndrome)
Both PIDs and Hyper IgE syndrome can cause recurrent infections, but PIDs encompass a wide range of immune system defects, while Hyper IgE syndrome is specifically characterized by high IgE levels. PID symptoms vary widely depending on the specific disorder but often include frequent infections, autoimmune issues, and an increased cancer risk. A comprehensive immune system evaluation, including blood tests to measure antibody levels and immune cell function, can help distinguish between PIDs and Hyper IgE syndrome. If your immune system issues are not limited to high IgE levels, a broader PID may be more likely than Hyper IgE syndrome.
Allergic Fungal Sinusitis
Allergic fungal sinusitis (AFS) is a condition where the sinuses become inflamed due to an allergic reaction to fungi, leading to chronic sinus infections, nasal congestion, and thick mucus formation.
How to Know if You Might Have Allergic Fungal Sinusitis vs. Hyper IgE Syndrome (Job Syndrome)
Both allergic fungal sinusitis and Hyper IgE syndrome can cause recurrent sinus infections, but AFS is specifically triggered by an allergic reaction to fungi, while Hyper IgE syndrome is associated with broader immune dysfunction. People with AFS may also experience nasal polyps, which are not typically seen in Hyper IgE syndrome. A sinus CT scan and allergy testing can help diagnose AFS, while blood tests showing high IgE levels are more indicative of Hyper IgE syndrome. If your sinus issues are primarily related to fungal allergies, AFS may be more likely than Hyper IgE syndrome.
Treatment Options for Hyper IgE Syndrome (Job Syndrome)
Medications
Antibiotics
Antibiotics are used to treat bacterial infections. In Hyper IgE syndrome, they help manage recurrent skin, lung, and other infections caused by immune dysfunction.
Antibiotics are prescribed when a bacterial infection is diagnosed or suspected. In some cases, patients may take antibiotics prophylactically to reduce the risk of frequent infections. The choice of antibiotic depends on the type and severity of the infection.
With proper use, antibiotics can significantly reduce infection-related symptoms and prevent complications. Improvement is usually seen within a few days of starting the medication.
Antihistamines
Antihistamines block histamine, a substance that causes allergic symptoms like itching, swelling, and rashes.
These medications help manage allergic reactions and skin symptoms in Hyper IgE syndrome, such as eczema or hives. They are typically taken orally and can be used as needed or regularly for ongoing symptom control.
Antihistamines provide quick relief from itching and other allergic symptoms, improving comfort and quality of life within hours of use.
Corticosteroids
Corticosteroids reduce swelling, redness, and irritation. They can be used topically or systemically (oral or injected) to manage inflammation.
In Hyper IgE syndrome, corticosteroids are used to treat severe skin inflammation, lung issues, or other inflammatory complications. They are typically reserved for more severe cases or flare-ups that do not respond to other treatments.
Patients can expect a reduction in inflammation and symptom relief within a few days of starting corticosteroids, though long-term use may be limited due to potential side effects.
Immunoglobulin Replacement Therapy
Immunoglobulin replacement therapy involves infusing antibodies (immunoglobulins) to help boost the immune system and prevent infections.
This therapy is used in patients with Hyper IgE syndrome who have low antibody levels or frequent infections not well-controlled with antibiotics. It is typically administered intravenously (IV) or subcutaneously (under the skin) on a regular basis.
Immunoglobulin replacement can reduce the frequency and severity of infections over time, with noticeable improvements often seen after several months of treatment.
Antifungal Medications
Antifungal medications treat fungal infections, which can be more common in people with weakened immune systems, such as those with Hyper IgE syndrome.
These medications may be prescribed when a fungal infection is diagnosed, particularly in the skin, nails, or lungs. They can be taken orally, applied topically, or administered intravenously, depending on the infection’s severity.
Antifungal treatment can resolve symptoms within a few weeks, though chronic or recurrent infections may require long-term therapy.
Topical Steroids
Topical steroids are creams or ointments that reduce inflammation and itching when applied to the skin.
They are commonly used to manage eczema and other skin conditions associated with Hyper IgE syndrome. Topical steroids are applied directly to affected areas and are often used in combination with moisturizers and other skin care treatments.
Patients can expect relief from itching and a reduction in skin inflammation within a few days of consistent use.
Leukotriene Receptor Antagonists
Leukotriene receptor antagonists block leukotrienes, chemicals that contribute to inflammation and allergic reactions.
These medications are sometimes used to manage asthma-like symptoms or allergic reactions in patients with Hyper IgE syndrome. They are typically taken orally and may be used in combination with other treatments.
Leukotriene receptor antagonists can help reduce respiratory symptoms and improve lung function over time, with noticeable improvements within a few weeks of starting the medication.
Monoclonal Antibodies
Monoclonal antibodies are lab-made proteins that target specific parts of the immune system to reduce inflammation or prevent infections.
In Hyper IgE syndrome, monoclonal antibodies may be used in more severe cases to help control immune system dysfunction. These treatments are typically administered via injection or IV infusion and are reserved for patients who do not respond to other therapies.
Patients may experience a reduction in symptoms and fewer infections over time, though the effects can vary depending on the specific monoclonal antibody used.
Vitamin D Supplements
Vitamin D supplements correct vitamin D deficiency, common in patients with Hyper IgE syndrome, which can contribute to bone weakness and immune dysfunction.
These supplements are taken orally and are often recommended for patients with low vitamin D levels. They may be used in combination with other treatments to support overall health and immune function.
With regular use, vitamin D supplements can help improve bone health and support the immune system, though it may take several months to see significant improvements.
Procedures
In addition to medications, certain procedures may be recommended for patients with Hyper IgE syndrome to manage complications or improve quality of life. These procedures are typically reserved for more severe cases or when other treatments are not effective.
Drainage of Abscesses
Abscesses are pockets of pus that can form in the skin or other tissues due to infection. In patients with Hyper IgE syndrome, abscesses are common and may require drainage to relieve pain and prevent further complications.
Abscess drainage is a minor surgical procedure in which a healthcare provider makes a small incision to release the pus. This procedure is typically performed in a clinic or hospital setting.
After drainage, patients usually experience immediate relief from pain and swelling, though antibiotics may be prescribed to prevent further infection.
Sinus Surgery
Chronic sinus infections are common in patients with Hyper IgE syndrome. In some cases, surgery may be necessary to remove blockages or improve drainage in the sinuses.
Sinus surgery is typically recommended when infections are recurrent or do not respond to medications. The procedure is performed by an ear, nose, and throat (ENT) specialist and may involve removing polyps or other obstructions.
Patients can expect improved sinus function and fewer infections after surgery, though recovery may take several weeks.
Improving Hyper IgE Syndrome (Job Syndrome) and Seeking Medical Help
In addition to medical treatments, several home remedies and lifestyle changes can help manage symptoms of Hyper IgE syndrome and improve quality of life.
Good Skin Care: Regularly moisturizing the skin and using gentle, fragrance-free products can help manage eczema and prevent skin infections.
Healthy Diet: Eating a balanced diet rich in vitamins and minerals, including vitamin D, can support overall health and immune function.
Regular Exercise: Staying active can help improve lung function and overall well-being, though patients should avoid activities that may trigger infections or allergic reactions.
Avoiding Triggers: Identifying and avoiding environmental triggers, such as allergens or irritants, can help reduce the frequency of allergic reactions and infections.
Stress Management: Managing stress through relaxation techniques, such as meditation or yoga, can help improve overall health and reduce the impact of chronic illness.
