Can Tezepelumab help with HES and steroid reduction?

Question

Hello doctor,

I have recently been diagnosed with hypereosinophilic syndrome (HES), leading to lung inflammation and frequent asthma-like attacks. My specialist mentioned Tezspire (Tezepelumab) as a potential treatment to lower my eosinophil levels and prevent respiratory complications.

How effective is Tezspire for conditions like HES beyond severe asthma? Can it reduce my steroid dependency? What are the potential long-term side effects or risks associated with its use in my situation? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Tezspire (Tezepelumab) is primarily approved for treating severe asthma (a chronic inflammatory disease of the airways) by reducing airway inflammation. It works by targeting thymic stromal lymphopoietin (TSLP), a key driver of airway inflammation. While its role in hypereosinophilic syndrome or HES (a rare disorder characterized by persistent and excessive eosinophils (a type of white blood cell) in the blood and tissues, leading to organ damage) is not well established, some experts believe it may help lower eosinophil levels and reduce steroid dependence. However, responses can vary between individuals, and its effectiveness for HES remains under investigation.

Since Tezspire modulates the immune system, there are potential long-term risks to consider. One concern is an increased risk of infections due to immune suppression. Additionally, altering eosinophil activity could have unintended consequences on immune function, though the full extent of these effects is not yet fully understood. Because of these potential risks, close medical supervision is necessary for patients considering Tezspire for off-label use in HES.

If you have HES and are exploring Tezspire as a treatment option, discussing the potential benefits and risks with your specialist is crucial. Regular monitoring will help assess how well the medication is working and whether any side effects develop over time. More research is needed to determine its safety and long-term effects in conditions beyond severe asthma.

I hope this helps.
