Ocrevus (ocrelizumab) is a medication primarily used to treat multiple sclerosis (MS), a chronic autoimmune disease affecting the central nervous system. It works by targeting and depleting a specific type of immune cell called CD20-positive B cells, which play a role in the abnormal immune response seen in MS. Steroids, on the other hand, are a class of drugs often used to reduce inflammation and suppress the immune system. They are commonly prescribed during MS relapses or flare-ups to quickly reduce inflammation and symptoms.
**Can Ocrevus be combined with steroids?** Yes, Ocrevus can be combined with steroids, but this combination must be managed carefully by healthcare providers due to potential risks and interactions related to immune system suppression.
Here is a detailed explanation of the considerations involved in combining Ocrevus with steroids:
### Purpose of Combining Ocrevus and Steroids
– **Ocrevus** is a long-term disease-modifying therapy that reduces MS activity by depleting B cells.
– **Steroids** (such as methylprednisolone or prednisone) are often used short-term to treat acute MS relapses by rapidly reducing inflammation.
– During an MS relapse, a patient on Ocrevus may receive steroids to manage symptoms while continuing Ocrevus for ongoing disease control.
### Immune System Effects and Risks
– Both Ocrevus and steroids suppress the immune system but through different mechanisms.
– Ocrevus depletes B cells, which are part of the adaptive immune system.
– Steroids broadly suppress inflammation and immune responses, affecting multiple immune cells.
– Combining these can lead to **additive immunosuppression**, increasing the risk of infections, including serious viral infections such as herpes simplex or varicella zoster.
– There have been reports of serious infections, including life-threatening herpes virus infections, in patients treated with Ocrevus, especially when combined with other immunosuppressive therapies like steroids.
– Because of this, doctors carefully weigh the benefits and risks before prescribing steroids alongside Ocrevus and monitor patients closely for signs of infection.
### Timing and Dosage Considerations
– Steroids are typically given in short courses during relapses, often as high-dose intravenous infusions over a few days.
– Ocrevus infusions are scheduled every six months.
– Steroid treatment for relapses can be administered without stopping Ocrevus, but the timing and dosage are tailored to minimize overlapping immunosuppression.
– Long-term or frequent steroid use alongside Ocrevus is generally avoided due to increased risk of adverse effects.
### Monitoring and Precautions
– Patients receiving Ocrevus and steroids should be monitored for infections, liver function, and other potential side effects.
– Vaccinations, especially live vaccines, are generally avoided during Ocrevus treatment because of the risk of infection.
– Patients should report symptoms such as fever, chills, rash, or unusual fatigue promptly.
– Blood tests and clinical evaluations are used to assess immune status and detect complications early.
### Potential Benefits of Combination
– Using steroids during relapses can provide rapid symptom relief and reduce inflammation.
– Continuing Ocrevus during steroid treatment helps maintain long-term disease control and reduce relapse frequency.
– This combination approach allows for both immediate and sustained management of MS.
### Risks and Side Effects
– Increased susceptibility to infections, including respiratory and herpes virus infections.
– Possible additive side effects such as elevated blood sugar, mood changes, and adrenal suppression from steroids.
– Potential liver injury or immune-mediated complications, though these are less common.
### Clinical Practice and Recommendations
– Neurologists and MS specialists often prescribe steroids during acute relapses even if the patient is on Ocrevus.
– The combination is used with caution, with close monitoring and patient education about infection risks.
