Systemic Medications for Eczema: Are They Right for You?

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that affects millions worldwide. Characterized by¹ itchy, red, swollen, and cracked skin, eczema can range from mild to severe, significantly impacting the quality of life for those who suffer from it. While topical treatments are often the first line of defense, there are instances where these are simply not enough. In such cases, healthcare professionals may consider Systemic Medications to manage the condition effectively. This comprehensive guide will delve into when Systemic Medications become a necessary part of eczema treatment, exploring the different types available, their benefits, risks, and what patients should know.

Understanding the Burden of Eczema

Before we discuss Systemic Medications, it’s crucial to understand the multifaceted burden of eczema. Beyond the visible skin symptoms, individuals with eczema often experience intense itching that can disrupt sleep, lead to anxiety and depression, and interfere with daily activities. Children with eczema may face challenges in school and social interactions, while adults might find their work and personal lives affected. The constant cycle of itching and scratching can lead to skin infections, further complicating the condition and requiring additional treatment.

The severity of eczema varies greatly among individuals. Some may experience occasional mild flare-ups that are easily managed with over-the-counter remedies and basic skincare. Others, however, face persistent and severe eczema that covers large areas of the body, causing significant discomfort and impacting their overall well-being. It is in these more severe cases that Systemic Medications often play a critical role.

The Role of Topical Treatments in Eczema Management

Topical treatments, such as corticosteroids and calcineurin inhibitors, are the cornerstone of eczema management for many individuals. These medications are applied directly to the affected skin to reduce inflammation and relieve itching. Emollients, or moisturizers, are also essential for maintaining the skin barrier and preventing flare-ups.

Topical corticosteroids come in various potencies, ranging from mild to very potent. The choice of potency depends on the severity and location of the eczema. Calcineurin inhibitors offer an alternative to corticosteroids, particularly for long-term use and on sensitive areas like the face and neck.

While topical treatments are effective for mild to moderate eczema, they may not be sufficient for individuals with severe or widespread disease. In these situations, the inflammation is often too extensive to be adequately controlled by topical applications alone. This is where the need for Systemic Medications arises.

When Topical Treatments Fall Short: Recognizing the Need for Systemic Intervention

Several indicators suggest that topical treatments may not be enough to manage eczema effectively, signaling the potential need for Systemic Medications:

Extensive Body Surface Area Involvement

When eczema affects a large percentage of the body’s surface area, applying topical medications can become impractical and may not provide sufficient relief. Systemic Medications, on the other hand, work throughout the entire body, addressing inflammation wherever it occurs.

Severe and Persistent Symptoms

If eczema symptoms, particularly intense itching and widespread rash, persist despite consistent and appropriate use of topical treatments, it may indicate the need for a more potent, systemic approach. Uncontrolled itching can significantly impact sleep and daily functioning, necessitating a treatment that can provide broader relief.

Frequent and Severe Flare-Ups

Individuals who experience frequent and severe eczema flare-ups, requiring repeated courses of topical corticosteroids, may benefit from Systemic Medications to help control the underlying inflammation and reduce the frequency and intensity of these episodes.

Impact on Quality of Life

When eczema significantly impacts a person’s quality of life, affecting their sleep, mood, social interactions, or ability to perform daily tasks, Systemic Medications may be considered to provide better symptom control and improve overall well-being.

Failure of Topical Medications

If a patient has diligently used topical medications as prescribed by their healthcare provider and has not experienced adequate improvement in their eczema symptoms, it suggests that a different approach, such as Systemic Medications, might be necessary.

Complications of Eczema

In some cases, severe eczema can lead to complications such as recurrent skin infections or eczema herpeticum (a severe viral infection). Systemic Medications may be needed to control the underlying inflammation and prevent or manage these complications.

Introducing Systemic Medications: A Body-Wide Approach

Systemic Medications for eczema are drugs that are taken orally or by injection and work throughout the body to reduce inflammation. These medications are typically reserved for individuals with moderate to severe eczema that has not responded adequately to topical treatments.

There are several types of Systemic Medications used to treat eczema, each with its own mechanism of action, benefits, and potential side effects. The choice of Systemic Medication depends on various factors, including the severity of the eczema, the patient’s overall health, and their response to previous treatments.

Types of Systemic Medications for Eczema

Oral Corticosteroids

Oral corticosteroids, such as prednisone, are potent anti-inflammatory medications that can provide rapid relief from severe eczema flare-ups. They work by suppressing the immune system, reducing inflammation throughout the body.

While highly effective for short-term management of severe eczema, oral corticosteroids are generally not recommended for long-term use due to their potential for significant side effects, including weight gain, mood changes, increased risk of infections, bone loss, and high blood pressure. Therefore, they are typically used for short courses to gain control of severe flares, often as a bridge to other longer-term Systemic Medications.

Traditional Immunosuppressants

Traditional immunosuppressants work by broadly suppressing the immune system, thereby reducing the inflammation associated with eczema. These medications are often used for moderate to severe eczema that has not responded to topical treatments. Common traditional immunosuppressants used for eczema include:

Cyclosporine

Cyclosporine is an immunosuppressant that works by inhibiting the activity of T cells, a type of immune cell that plays a key role in the inflammation associated with eczema. It can be effective in controlling severe eczema but requires careful monitoring due to potential side effects such as kidney problems, high blood pressure, and increased risk of infections.

Methotrexate

Methotrexate is another immunosuppressant that is sometimes used to treat severe eczema. It works by interfering with the growth of certain cells in the body, including immune cells. Potential side effects of methotrexate include liver problems, lung inflammation, and bone marrow suppression, necessitating regular blood tests.

Azathioprine

Azathioprine is an immunosuppressant that works by inhibiting the production of DNA and RNA in immune cells. It can be effective in treating eczema but may take several weeks to months to show its full effect. Side effects can include nausea, vomiting, diarrhea, and an increased risk of infections. Regular blood tests are required to monitor for potential liver problems and bone marrow suppression.

Mycophenolate Mofetil

Mycophenolate mofetil is an immunosuppressant that works by inhibiting an enzyme involved in the production of DNA in immune cells. It is sometimes used off-label to treat severe eczema. Common side effects include gastrointestinal issues such as nausea, vomiting, and diarrhea.

Biologics

Biologics are a newer class of Systemic Medications that target specific components of the immune system involved in the development of eczema. This targeted approach can lead to fewer widespread side effects compared to traditional immunosuppressants. Several biologics have been approved for the treatment of moderate to severe eczema:

Dupilumab

Dupilumab is a monoclonal antibody that blocks the action of two key proteins, interleukin-4 (IL-4) and interleukin-13 (IL-13), which are major drivers of the type 2 inflammation seen in eczema. It is administered by subcutaneous injection every two weeks (or every four weeks at a higher dose). Dupilumab has shown significant efficacy in reducing eczema symptoms and improving quality of life, with a generally favorable safety profile. Common side effects include injection site reactions and conjunctivitis.

Tralokinumab

Tralokinumab is another monoclonal antibody that specifically targets interleukin-13 (IL-13). It is also administered by subcutaneous injection every two weeks. Clinical trials have demonstrated that tralokinumab can significantly improve eczema symptoms, including skin clearance and itch reduction. Common side effects include upper respiratory tract infections, conjunctivitis, and injection site reactions.

Lebrikizumab

Lebrikizumab is a monoclonal antibody that selectively binds to interleukin-13 (IL-13), preventing it from binding to its receptor and subsequently inhibiting downstream signaling. It is administered by subcutaneous injection every two weeks for the initial few doses, followed by every four weeks as maintenance therapy. Clinical studies have shown that lebrikizumab can lead to significant improvements in eczema signs and symptoms. Common side effects include injection site reactions, conjunctivitis, and headache.

Oral Janus Kinase (JAK) Inhibitors

Oral JAK inhibitors are a class of Systemic Medications that work by blocking the activity of Janus kinases (JAKs), a family of enzymes that play a crucial role in the signaling pathways of various cytokines involved in inflammation, including those implicated in eczema. Several JAK inhibitors have been approved for the treatment of moderate to severe eczema:

Upadacitinib

Upadacitinib is a selective JAK1 inhibitor taken orally once daily. Clinical trials have demonstrated its efficacy in significantly improving skin clearance, reducing itch, and improving quality of life in adults and adolescents with moderate to severe eczema. Common side effects can include upper respiratory tract infections, nausea, headache, and increased blood creatinine.

Abrocitinib

Abrocitinib is another selective JAK1 inhibitor administered orally once daily. Studies have shown that abrocitinib can rapidly improve eczema signs and symptoms, including itch, and is effective in both short-term and long-term treatment. Common side effects may include nausea, headache, upper respiratory tract infections, and herpes simplex infections.

How Systemic Medications Work to Treat Eczema

Systemic Medications for eczema work by targeting different aspects of the immune system that contribute to the underlying inflammation and skin barrier dysfunction characteristic of the condition.

Corticosteroidi orali: Reduce inflammation by broadly suppressing the immune system.
Traditional Immunosuppressants (Cyclosporine, Methotrexate, Azathioprine, Mycophenolate Mofetil): Suppress the activity of various immune cells, such as T cells, and interfere with their function.
Biologics (Dupilumab, Tralokinumab, Lebrikizumab): Specifically block the action of key cytokines (IL-4 and/or IL-13) that drive the type 2 inflammation in eczema.
Oral JAK Inhibitors (Upadacitinib, Abrocitinib): Inhibit the activity of JAK enzymes, which are involved in the signaling pathways of multiple pro-inflammatory cytokines.

By modulating these immune responses, Systemic Medications can effectively reduce inflammation, relieve itching, improve skin clearance, and ultimately enhance the quality of life for individuals with moderate to severe eczema.

Benefits of Using Systemic Medications for Eczema

When topical treatments are insufficient, Systemic Medications can offer significant benefits for individuals with eczema:

Improved Symptom Control: Systemic Medications can effectively reduce the severity of eczema symptoms, including itching, redness, swelling, and skin dryness.
Increased Skin Clearance: Many Systemic Medications, particularly biologics and JAK inhibitors, can lead to significant clearing of the skin, reducing the extent and severity of the rash.
Reduced Frequency and Severity of Flare-Ups: Long-term use of certain Systemic Medications can help prevent or reduce the frequency and intensity of eczema flare-ups.
Improved Quality of Life: By controlling eczema symptoms, Systemic Medications can lead to significant improvements in sleep, mood, social participation, and overall well-being.
Potential for Long-Term Management: Some Systemic Medications, such as certain traditional immunosuppressants, biologics, and JAK inhibitors, can be used for long-term management of moderate to severe eczema.

Potential Risks and Side Effects of Systemic Medications

Mentre Systemic Medications can be highly effective, it’s important to be aware of their potential risks and side effects. The specific side effects vary depending on the type of medication used.

Corticosteroidi orali: Short-term side effects can include mood changes, increased appetite, and fluid retention. Long-term use can lead to more serious side effects such as weight gain, high blood pressure, bone loss, diabetes, and increased risk of infections.
Traditional Immunosuppressants: Cyclosporine can cause kidney problems and high blood pressure. Methotrexate can affect the liver and lungs. Azathioprine and mycophenolate mofetil can cause gastrointestinal issues and increase the risk of infections. Regular monitoring through blood tests is crucial with these medications.
Biologici: Common side effects of biologics like dupilumab, tralokinumab, and lebrikizumab often include injection site reactions and conjunctivitis. While generally considered safe, there is a theoretical risk of more serious infections or allergic reactions.
Oral JAK Inhibitors: Common side effects of upadacitinib and abrocitinib can include upper respiratory tract infections, nausea, headache, and herpes simplex infections. There may also be risks of more serious cardiovascular events or blood clots, particularly in individuals with pre-existing risk factors.

It is essential for patients to have a thorough discussion with their healthcare provider about the potential risks and benefits² of each Systemic Medication before starting treatment. Regular monitoring and follow-up are also crucial to manage any side effects and ensure the medication is working effectively.

The Decision-Making Process: When are Systemic Medications the Right Choice?

The decision to start Systemic Medications for eczema is a collaborative one between the patient and their healthcare provider, typically a dermatologo. Several factors are considered during this process:

Severity of Eczema: Systemic Medications are generally reserved for moderate to severe eczema that has not responded adequately to topical treatments.
Impact on Quality of Life: If eczema significantly affects a person’s daily life, despite optimal topical therapy, Systemic Medications may be considered.
Failure of Topical Treatments: When a patient has consistently used topical medications as prescribed without significant improvement, a systemic approach may be necessary.
Frequency of Flare-Ups: Frequent and severe flare-ups that require repeated courses of topical corticosteroids may indicate the need for a Systemic Medication to provide better long-term control.
Patient Preferences and Lifestyle: The patient’s preferences, lifestyle, and ability to adhere to a particular treatment regimen are also important considerations. For example, some patients may prefer oral medications over injections, or vice versa.
Overall Health and Medical History: The patient’s overall health, other medical conditions, and any existing medications will be taken into account to ensure the chosen Systemic Medication is safe and appropriate.
Potential Risks and Benefits: A thorough discussion of the potential risks and benefits of each Systemic Medication option is essential to help the patient make an informed decision.
