Stockholm, Sweden – Groundbreaking research from Karolinska Institutet is challenging previous assumptions about how biological drugs impact the immune system in individuals battling severe asthma. While these medications have considerably improved the lives of many, the latest findings indicate that some immune cells with high inflammatory potential persist, and may even increase, despite treatment.
Unexpected Immune Cell Behavior During asthma Treatment
Biological drugs, widely recognized as a crucial advancement in managing severe asthma, have now been scrutinized in a detailed study published in the journal *Allergy*. The research team, led by experts at Karolinska Institutet, investigated the effects of these drugs on the immune cells of patients.
Valentyna Yasinska, a consultant in pulmonary medicine at Karolinska University Hospital and doctoral student, noted that while biologics help control symptoms, their precise effects on the immune system remained largely unknown – until now.
key Findings from the Biologics Study
The analysis of blood samples from 40 patients before and during treatment revealed a counterintuitive result: certain immune cells, vital in asthma-related inflammation, actually increased in number. This revelation suggests that biologics might not address the fundamental cause of the condition.
Jenny Mjösberg, a professor of tissue immunology, suggests that continuous treatment might potentially be necessary to maintain control over the disease. This highlights the need for a deeper understanding of how these drugs interact with the immune system over extended periods.
Did You Know?
Asthma affects more than 26 million Americans, including over 6 million children, according to the Centers For Disease Control and Prevention (CDC).
The BIOCROSS Study: A foundation for Discovery
The research is rooted in data collected from severe asthma patients participating in the BIOCROSS study. Utilizing advanced techniques like flow cytometry and single-cell sequencing, researchers were able to thoroughly examine the characteristics and functions of the immune cells involved.
Lorenz Wirth, a doctoral student involved in the study, expressed surprise at the increased levels of inflammatory cells. He believes this could explain why airway inflammation often returns when treatment is reduced or stopped, emphasizing the importance of understanding the long-term immunological impacts of these drugs.
Pro Tip: Regular monitoring of your asthma symptoms and lung function can definitely help your doctor adjust your treatment plan as needed.
long-Term Effects Still Under investigation
Due to their relatively recent introduction, the long-term effects of biologics like mepolizumab and dupilumab are not yet fully understood. These drugs have been prescribed for less than a decade, making ongoing research crucial.
The next phase of the research will involve analyzing samples from patients with a longer treatment history and studying lung tissue to observe how immune cells are affected directly in the airways.
The study was supported by grants from various organizations, including the EU (Horizon 2020) and the Swedish Heart-Lung Foundation.
Understanding Asthma Biologic Treatments: Key Considerations
Here’s a comparison of key aspects of asthma biologic treatments based on the research:
| Aspect | Before Treatment | During Treatment | Implication |
|---|---|---|---|
| Inflammatory Immune Cells | Expected to decrease | Increased in some patients | May require continued treatment |
| Symptom Control | Uncontrolled | Improved in most patients | Highlights the need for long-term monitoring |
| Long-Term Effects | Unknown | Still under investigation | Further research needed |
- Do these findings change your perspective on asthma biologic treatments?
- What further research woudl you like to see conducted on the long-term effects of these drugs?
Evergreen Insights on Asthma Management
Beyond medication, managing asthma effectively involves identifying and avoiding triggers such as allergens, pollutants, and irritants. Regular exercise and maintaining a healthy weight can also improve lung function and reduce asthma symptoms. it’s also vital to have an updated asthma action plan, and ensure you use your medications correctly.
Frequently Asked Questions About Asthma and Biologics
- What are biological drugs for asthma? Biological drugs, or biologics, are a key treatment for severe asthma, helping to manage symptoms. The exact way they influence the immune system has been unclear until recently.
- What did the new asthma study reveal? The recent study indicated that certain immune cells, crucial in asthma inflammation, increased instead of decreasing during biologic treatment. This suggests that the treatment might not target the underlying cause.
- Why is understanding the long-term effects of asthma biologics important? Because biologics are relatively new, their long-term effects are not fully known. understanding these effects is vital to ensure effective management of asthma.
- How was the asthma study conducted? Researchers analyzed blood samples from 40 severe asthma patients before and during treatment, using advanced methods such as flow cytometry and single-cell sequencing to study the immune cells.
- What are the next steps in asthma research? The next phase involves analyzing samples from patients with a long treatment history,and examine lung tissue to understand how immune cells are affected in the airways.
- Are asthma biologics a permanent cure? The study suggests that asthma biologics may not attack the root of the problem, and continued treatment might potentially be necessary to keep the disease under control. So, they are not a permanent cure.

Why do asthma attacks happen even when someone is already using prescribed medication?
Asthma Relapse: Why Even Strong Drugs Fail
Asthma, a chronic respiratory disease, affects millions worldwide. While medications like bronchodilators and corticosteroids are designed to control asthma symptoms and prevent asthma attacks, relapse can still occur. Understanding the causes behind these failures is crucial for effective asthma management and a better quality of life. This article delves into the reasons why even strong asthma drugs sometimes fall short, exploring triggers, complications, and strategies for improved control.
Common Causes of Asthma Relapse
Asthma relapse can be a frustrating experience, and understanding the root causes is the first step in preventing it. Several factors, ofen working in concert, contribute to these setbacks, even when powerful medications are being used.
Inadequate Medication Use
One of the most frequently overlooked causes of asthma relapse is *inadequate medication use*. This can encompass several issues, including:
- Incorrect Inhalation Technique: Proper technique is vital for the medication to reach your lungs.Using an inhaler improperly can render the medication ineffective.
- Non-Adherence to Regimen: Failing to take medications as prescribed, whether due to forgetfulness or lack of understanding, substantially increases the risk of relapse.
- Dosage Errors: Taking the wrong dose, either too little or too much, can disrupt asthma control.
Environmental Triggers
Environmental factors play a notable role in asthma flares or exacerbation. Identifying and avoiding these triggers is essential.
- Allergens: Pollen, dust mites, pet dander, and mold are common asthma triggers. Regular allergy testing can help pinpoint specific allergens to avoid.
- Irritants: Smoke (tobacco, wood), strong odors (perfumes, cleaning products), and air pollution can irritate airways and worsen asthma control.
- Weather Changes: Cold air, humidity, and thunderstorms can trigger asthma symptoms in some individuals.
underlying Medical Conditions
Concurrent medical conditions can worsen asthma and increase the likelihood of relapse.
- Respiratory Infections: Viral infections like the common cold and the flu are frequent catalysts for asthma exacerbations.
- Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the airways and exacerbate asthma.
- Obesity: Excess weight can make breathing more arduous and reduce the effectiveness of asthma medications.
Why Asthma Medications fail: Understanding medication Resistance
Sometimes, even the most potent asthma medications fail to provide relief.This isn’t always due to a lack of inherent effectiveness,but can be linked to different aspects of the disease itself,or interaction between drugs.
Bronchial Inflammation
Persistent airway inflammation, even with medication, can make it harder for the medicine to reach the lungs.
Medication Dependence or Tolerance
Long-term use can lead to what is called medication dependence. your body might become used to the drug, and it will need a higher dose to fight the symptoms.
Poor Lung Function
Significant damage from repeated asthma attacks or underlying conditions may decrease lung function,making medications less effective.
Strategies for Improving Asthma Control and Preventing Relapse
While asthma relapse can be challenging, several strategies can optimize asthma control and minimize the risk of future flare-ups.
Personalized Asthma Action Plan
Working with your doctor to create an *personalized asthma action plan* is critical. This plan should include:
- Daily Medication Regimen: A clear schedule for taking your controller and rescue medications.
- Trigger Identification and Avoidance: Strategies to avoid known triggers.
- Symptom Monitoring: Instructions on how to recognise early signs of an exacerbation and what steps to take.
Regular Medical Check-Ups and Monitoring
Attend regular check-ups with your physician to monitor your asthma, medications, and overall health. This includes:
- Pulmonary Function Tests: Evaluating lung function to assess the effectiveness of asthma control.
- Medication Adjustments: Regular evaluation of treatments to make any necessary adjustments.
- Education and Support: Learning and re-enforcing proper inhaler technique and more.
Lifestyle Modifications
Adopting healthy lifestyle habits can significantly improve asthma control. These include:
- Avoidance of Triggers: Take active steps to avoid identified asthma triggers.
- regular Exercise: As tolerated and appropriate for your condition, regular exercise may improve lung function and reduce asthma symptoms. Always check with your doctor first.
- healthy Diet: A balanced diet supports overall health,which can in turn support asthma management.
- Smoking Cessation: If you smoke, quitting is crucial to improve asthma management.
