Treatment Options

If you have been told you have bronchiectasis, you may be wondering what it really means, what caused it, and what you can do about it. This chronic lung condition is not as widely recognized as asthma or COPD, but it is just as important to diagnose and manage properly. Let’s take a closer look at what bronchiectasis is, how it develops, how doctors diagnose it, and the modern treatment strategies—including new medications like brensocatib (Brinsupri)—that are changing the outlook for patients.

What Is Bronchiectasis?

Bronchiectasis is a disease where the airways in the lungs become abnormally widened, scarred, and damaged. In a healthy lung, the airways act like flexible tubes that carry air in and out while moving mucus up and out efficiently. In bronchiectasis, however, the airway walls lose their normal structure. They become floppy and scarred, mucus clearance is impaired, and secretions collect instead of being swept away. This stagnant mucus creates the perfect environment for bacteria to grow. Over time, repeated cycles of infection and inflammation cause even more airway damage. The result is a vicious cycle: damaged airways, mucus buildup, infection, inflammation, and more airway injury.

What Causes Bronchiectasis?

There are many possible causes of bronchiectasis. Sometimes, the exact cause is never found. It may occur after a severe lung infection, or in people with chronic lung diseases such as COPD, cystic fibrosis, or severe asthma. Immune system problems that make it harder to fight infections can play a role, as can recurrent aspiration or reflux, where food or stomach acid repeatedly enters the lungs. In other cases, rare genetic or structural problems with the airways are to blame.

Certain conditions are often seen alongside bronchiectasis and can make it worse. Two of the most important are nontuberculous mycobacteria (NTM), which are slow-growing bacteria that can cause chronic lung infection, and allergic bronchopulmonary aspergillosis (ABPA), an allergic reaction to a common fungus that drives inflammation and mucus plugging.

Recognizing the Symptoms

The symptoms of bronchiectasis can look very similar to other lung diseases, which is why it is often underdiagnosed. A chronic cough is almost always present, and patients often bring up mucus on a daily basis. Recurrent chest infections that require antibiotics are another hallmark, along with shortness of breath, wheezing, fatigue, and reduced exercise tolerance.

The best way to confirm bronchiectasis is with a CT scan of the chest, which clearly shows the widened and irregular airways. Other parts of the evaluation may include sputum cultures to check for bacteria or fungi, blood tests to evaluate the immune system, and pulmonary function tests to see how well the lungs are working.

Treatment Strategies

There is no cure that can reverse the airway damage once it has developed, but treatment can dramatically improve quality of life, reduce infections, and slow disease progression.

The cornerstone of management is daily airway clearance. Chest physiotherapy, special breathing exercises, and mechanical techniques such as oscillatory flutter devices or vest therapy help mobilize mucus. Inhaled saline solutions, especially hypertonic saline, can thin mucus and make it easier to clear.

Antibiotics are used both for acute flare-ups and, in select cases, for long-term suppression. Some patients inhale antibiotics such as tobramycin to reduce bacterial load in the lungs. Certain oral antibiotics, like azithromycin, may also reduce flare-ups because of their anti-inflammatory effects.

One of the most promising developments in the field is the drug brensocatib (Brinsupri). This new oral therapy is designed to block an enzyme called neutrophil elastase, which drives much of the destructive inflammation in bronchiectasis. Clinical trials have shown that it may significantly reduce the number of exacerbations and help preserve lung function. This is now FDA approved and is an exciting step forward that offers hope for patients with frequent flare-ups despite standard therapy.

It is also essential to treat any coexisting conditions that worsen bronchiectasis. Patients with NTM infections often require long-term, multi-drug antibiotic regimens tailored to the specific type of bacteria. Those with ABPA may need steroids to reduce inflammation, along with antifungal medications.

Living with Bronchiectasis

Good overall lung health is another critical part of management. Vaccines such as influenza, pneumococcal, and COVID-19 are highly recommended. Smoking cessation is crucial, and pulmonary rehabilitation programs can help improve stamina and breathing efficiency.

Although bronchiectasis is a chronic condition, many people live active and fulfilling lives when they follow a structured care plan. Daily airway clearance, prompt recognition of infections, and regular follow-up with a pulmonary team are all important. With new therapies like brensocatib, treatment is expanding beyond symptom control and beginning to address the underlying drivers of inflammation.

Key Takeaway

Bronchiectasis is a condition where damaged airways trap mucus and lead to repeated infections, but it is manageable. With daily airway clearance, antibiotics, and new targeted therapies, many patients can breathe easier and live fuller lives.

New Advances in COPD Treatment: Biologics and Beyond

By: Michael S. Alvarez, DO, MPH, FCCP


Chronic Obstructive Pulmonary Disease (COPD) affects millions of people and remains one of the most common causes of breathing disorders worldwide. For decades, treatment has centered around inhalers, steroids, oxygen, and lifestyle changes. These remain essential, but now there are exciting new therapies that can target the disease in more precise ways.

Some of the biggest breakthroughs are biologic medications like Dupixent and Nucala, which have been used for asthma and are now approved for certain COPD patients. Another new medication, Ohtuvayre, is the first inhaled COPD medication to be approved in more than a decade.

The Foundation of COPD Care

The starting point for COPD treatment is usually maintenance inhalers. Dual therapy inhalers combine two types of medicines, while triple therapy adds an inhaled steroid for more complete control.

When a flare-up—also called an exacerbation—occurs, patients may need a short course of oral steroids such as prednisone, sometimes combined with antibiotics or nebulizer treatments.

But repeated steroid bursts can lead to adverse effects over time, including bone loss, weight gain, diabetes, high blood pressure, and higher infection risk. Even more concerning, the more flare-ups a patient experiences, the faster their lung function declines, which often leads to even more flare-ups. This is the dangerous cycle these new treatments aim to break.

Why Eosinophils Matter in COPD

To understand why biologics work, it helps to know about eosinophils—a type of white blood cell. They normally help fight infections, but in some COPD patients, especially those with chronic bronchitis, high eosinophil levels cause ongoing inflammation in the airways.

Eosinophil counts are measured with a simple blood test. Levels of 150 cells/μL or higher may indicate that a patient could benefit from Nucala. Levels of 300 cells/μL or higher show the strongest evidence for benefit from both Nucala and Dupixent. Patients with high eosinophil counts often have more flare-ups and may respond better to therapies that specifically target these cells.

Dupixent: A Targeted Option for High Eosinophil COPD

Dupixent has been a trusted asthma treatment for years and is now approved for certain COPD patients. It is designed for people with chronic bronchitis-type COPD, eosinophil counts of at least 300 cells/μL, and frequent flare-ups despite being on triple inhaler therapy.

It works by blocking two inflammatory proteins, IL-4 and IL-13, that drive swelling, mucus production, and airway wall thickening. For eligible patients, Dupixent can reduce flare-ups, improve lung function, and make day-to-day breathing easier.

Nucala: Expanding Access to Biologic Therapy

Nucala is another biologic that has been used in asthma for years and is now available for certain COPD patients. It can be prescribed for people with eosinophil counts of 150 cells/μL or higher, with the best results seen at 300 or more.

Nucala targets IL-5, a protein that eosinophils need to survive. By lowering eosinophil numbers, Nucala reduces inflammation in the lungs and decreases the frequency of exacerbations. This makes it an important option for patients whose COPD is driven by eosinophilic inflammation but who may not meet the higher threshold for Dupixent.

Ohtuvayre: A Dual-Action Inhaled Breakthrough

Ohtuvayre represents a major step forward as the first inhaled COPD medication approved in over a decade. It is delivered via nebulizer, allowing the medication to reach the lungs directly.

What makes Ohtuvayre unique is that it works in two ways at once. It relaxes the muscles around the airways so air can flow more freely, and it reduces inflammation to limit swelling and mucus buildup. This is achieved by blocking two enzymes, PDE3 and PDE4, that are involved in both airway tightening and inflammation.

Unlike the biologics, Ohtuvayre can be used regardless of eosinophil levels, making it an option for patients who still have daily shortness of breath despite being on standard inhalers.

Fitting These Treatments Into the COPD Care Plan

COPD care can be thought of as a ladder. The first steps are lifestyle changes—quitting smoking and exercising. Next comes medication with dual or triple inhaler therapy. When flare-ups occur, short courses of steroids and antibiotics may be necessary.
If symptoms or exacerbations persist, advanced options come into play. Dupixent is for patients with high eosinophils and frequent flare-ups. Nucala can be used at lower eosinophil counts but is most effective at higher levels. Ohtuvayre is for persistent breathlessness, no matter what the eosinophil level.

The Promise of Personalized COPD Care

These new therapies mark a shift from “one-size-fits-all” to precision medicine in COPD. By targeting the specific type of inflammation driving the disease, they can reduce flare-ups, protect lung function, and improve overall quality of life.
