T-Cell Costimulation Blockers: Effective Autoimmune Disease Treatment
Introduction: Key Points on T-cell Costimulation Blockers
T-cell costimulation blockers are a type of immunosuppressive medication used to manage autoimmune conditions such as rheumatoid arthritis. These drugs work by targeting specific immune cells, helping to reduce inflammation and prevent the immune system from mistakenly attacking healthy tissues. They are often considered when other treatments have not provided sufficient relief. If you have an autoimmune disorder, discussing the possibility of using a T-cell costimulation blocker with your healthcare provider may be worthwhile.
Medications in the T-cell Costimulation Blocker Class
Abatacept (Abatacept)
Orencia (Abatacept)
The generic name is the official medical name of the drug, while the brand name is assigned by the manufacturer. The generic name is listed in parentheses.
How T-cell Costimulation Blockers Work: Mechanism of Action
T-cell costimulation blockers work by interfering with the activation of T-cells, a type of white blood cell that plays a key role in the immune system. In autoimmune diseases, T-cells mistakenly attack the body’s own tissues, leading to inflammation and damage. Normally, T-cells require two signals to become fully activated. T-cell costimulation blockers, such as abatacept, block the second signal, preventing the T-cells from becoming fully activated and attacking healthy tissue.
All medications in this class function similarly, as they target the same pathway to reduce overactivity in the immune system.
Benefits of T-cell Costimulation Blockers for Autoimmune Disease Treatment
T-cell costimulation blockers are commonly prescribed for autoimmune diseases like rheumatoid arthritis, psoriatic arthritis, and juvenile idiopathic arthritis. These medications are particularly beneficial for patients who have not responded well to other treatments, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or disease-modifying antirheumatic drugs (DMARDs). One of the key advantages of T-cell costimulation blockers is their ability to specifically target T-cells, reducing inflammation without broadly suppressing the entire immune system. This targeted approach may lead to fewer side effects compared to other immunosuppressive therapies.

Potential Side Effects of T-cell Costimulation Blockers
As with any medication, T-cell costimulation blockers can cause side effects. While many individuals tolerate these drugs well, it’s important to be aware of potential risks. Below is a list of side effects, ranging from the most common to the least common. If you experience any side effects, particularly severe ones, contact your healthcare provider immediately. You can also schedule a telemedicine visit with one of our providers to discuss your symptoms.
Common Side Effects of T-cell Costimulation Blockers
Headache: Occurs in about 12% of patients. This is the most frequently reported side effect and is generally mild. However, if headaches persist or worsen, consult your doctor.
Upper respiratory tract infections: Reported in approximately 9% of patients. Symptoms may include a runny nose, sore throat, and cough. Individuals with pre-existing respiratory conditions, such as asthma, may be at higher risk.
Nausea: Affects around 8% of patients. Nausea is usually mild and temporary but can be uncomfortable. If nausea becomes severe or persistent, speak with your healthcare provider.
Fatigue: Experienced by about 7% of patients. Fatigue can range from mild to moderate and may improve over time as your body adjusts to the medication.
Fever: Occurs in about 6% of patients. Fever may indicate an infection or immune response, so monitor your temperature and consult your doctor if the fever is high or persistent.
Less Common Side Effects (1% to 5%)
Joint pain (arthralgia): Occurs in about 4% of patients. This can interfere with daily activities and may require pain management strategies.
High blood pressure (hypertension): Reported in 3% of patients. If you have a history of high blood pressure, your doctor may monitor your blood pressure more closely while you are on this medication.
Urinary tract infections (UTIs): Occur in about 2% of patients. Symptoms may include painful urination, frequent urination, or blood in the urine. If you experience these symptoms, contact your healthcare provider.
Back pain: Affects approximately 2% of patients. This side effect is usually mild but can be uncomfortable. If back pain persists, consult your doctor.
Rare Side Effects (Less than 1%)
The following side effects are rare but can still occur. If you experience any of these, contact your healthcare provider immediately:
Rash, dizziness, shortness of breath, chest pain, swelling of the face or extremities, severe allergic reactions (anaphylaxis), liver enzyme abnormalities, and gastrointestinal issues such as diarrhea or constipation.
Severe Side Effects of T-cell Costimulation Blockers
Although uncommon, some side effects can be serious and require immediate medical attention. These include:
Serious infections: T-cell costimulation blockers can suppress the immune system, increasing the risk of infections such as pneumonia or sepsis. Symptoms of infection include fever, chills, cough, or difficulty breathing. If you experience any of these symptoms, seek medical help immediately.
Allergic reactions: Severe allergic reactions (anaphylaxis) are rare but possible. Symptoms may include swelling of the face, lips, or throat, difficulty breathing, and hives. This is a medical emergency, and you should seek immediate care.
Liver problems: In rare cases, T-cell costimulation blockers can affect liver function. Symptoms of liver issues include yellowing of the skin or eyes (jaundice), dark urine, and severe abdominal pain. Contact your healthcare provider if you notice any of these signs.
It’s essential to discuss any side effects with your healthcare provider before starting a T-cell costimulation blocker. You can schedule a telemedicine appointment with one of our providers to ensure this medication is appropriate for you and to address any concerns you may have.
Drug to Drug Interactions
T-cell costimulation blockers can interact with other medications, potentially affecting their efficacy or increasing the likelihood of side effects. It is essential to inform your healthcare provider about all the medications you are currently taking, including over-the-counter drugs, supplements, and herbal remedies. Some known drug interactions include:
Immunosuppressive drugs: Combining T-cell costimulation blockers with other immunosuppressive medications (such as corticosteroids or biologics like TNF inhibitors) can elevate the risk of infections or other immune-related complications.
Live vaccines: T-cell costimulation blockers may reduce the effectiveness of live vaccines (such as MMR or varicella) and increase the risk of infection from the vaccine itself. It’s important to avoid live vaccines while taking this medication.
Blood thinners (anticoagulants): Patients using blood thinners (such as warfarin) may face an increased risk of bleeding when these are combined with T-cell costimulation blockers. Your healthcare provider may need to adjust your dosage or monitor you more closely.
Nonsteroidal anti-inflammatory drugs (NSAIDs): Taking NSAIDs (such as ibuprofen or naproxen) alongside T-cell costimulation blockers may heighten the risk of gastrointestinal issues, including ulcers or bleeding.
If you are taking any of these medications or have concerns about potential drug interactions, consider scheduling a telemedicine consultation with one of our providers to review your treatment plan.
Precautions and Contraindications
Before starting a T-cell costimulation blocker, it’s important to discuss your medical history with your healthcare provider. Certain conditions may increase the risk of side effects or make this medication unsuitable for you. Some key precautions and contraindications include:
History of infections: Since T-cell costimulation blockers suppress the immune system, patients with a history of recurrent or chronic infections (such as tuberculosis or hepatitis) should use this medication with caution.
Pregnancy and breastfeeding: The safety of T-cell costimulation blockers during pregnancy and breastfeeding is not well established. If you are pregnant, planning to become pregnant, or breastfeeding, discuss the potential risks and benefits with your healthcare provider.
