Azithromycin for Asthma AMAZES

Many doctors are unaware of the science supporting azithromycin for asthma. Learn why this antibiotic might help hard-to-treat asthma.

Hard-to-treat asthma can be a life-threatening lung disease. That’s why research from Australia suggesting that the antibiotic azithromycin (Zithromax) helps asthma is so exciting. The authors called their trial AMAZES (Asthma and Macrolides: AZithromycin Efficacy and Safety study). The results were very good if not amazing.

Asthma: A Changing Condition?

Asthma was once considered a serious but not life-threatening lung condition. William Osler, MD, has been described as the father of modern medicine. He was one of the founders of Johns Hopkins Medical School. Dr. Osler believed that no one died from asthma. He described the “asthmatic panting into old age.”

About 300 million people around the world have asthma, a chronic inflammation of the airways that causes wheezing and difficulty breathing. (According to the American Lung Association and the CDC, the current figure in the US is 26 million children and adults with asthma.) Thousands die each year and the financial costs top $50 billion.

Asthma Takes a Toll:

Such statistics do not capture the personal toll that asthma takes. Not being able to breathe is frightening. Some people curtail their activities in an attempt to avoid attacks. Others end up in the emergency room in acute distress, gasping for breath. Too many people die!

Some health professionals suggest that the reason for so many asthma deaths is that patients are “noncompliant.” We find that concept objectionable. Someone who is having difficulty breathing is highly motivated to get relief. As a teenager I (Joe) suffered from asthma. When you wake up in the middle of the night gasping for air the first thing you reach for is your inhaler.

Most people take their medicine because the memory of a severe asthma attack does not fade. In our opinion, asthmatics are highly motivated to comply with a prescribed regimen and prevent another serious attack and/or a trip to the emergency department.

Drugs for Asthma:

The usual treatments for asthma include inhaled corticosteroids such as fluticasone (Flovent), budesonide (Pulmicort) or mometasone (Asmanex). These help to control inflammation.

Many people also need medication to open airways (bronchodilators). The oldest and simplest would be drugs like albuterol (ProAir HFA, Ventolin HFA). Salmeterol and formoterol are long-acting bronchodilators that are often combined with corticosteroids. Brands include Advair, Dulera and Symbicort.

Leukotriene modifiers like montelukast (Singulair) or zileuton (Zyflo) calm the immune system and reduce inflammation. Doctors may prescribe them in addition to other medications, especially to people whose asthma appears to be triggered by allergies.

Hard-To-Treat Asthma:

Despite standard medical treatment, a certain proportion of asthma sufferers continue to have serious breathing difficulty. They may experience asthma exacerbations that can land them in the emergency department. In fact, nearly two million ER visits annually are due to asthma attacks. No wonder doctors have been anxious to find a way to reduce these complications.

Azithromycin for Asthma

A study from Australia (AMAZES) showed that adding the antibiotic azithromycin to the regular regimen made a significant difference (The Lancet, online July 4, 2017). . Over 400 hard-to-treat patients were recruited. They received either azithromycin or placebo three times a week for 12 months in addition to their regular inhaled medication. The people who took the antibiotic had 40 percent fewer severe attacks and a better quality of life.

An editorial in The Lancet summarizes the importance of this research:

“…affordable, effective, and safe add-on therapies in patients with poorly controlled asthma are needed. Previous studies have shown a beneficial effect of macrolide antibiotics such as azithromycin on asthma symptoms, but their effect on asthma exacerbations has been inconclusive due to a lack of large long-term trials.”

The authors go on to note:

“Azithromycin improved asthma-related quality of life across all domains of the Asthma-specific Quality of Life Questionnaire.  Additionally, azithromycin use was associated with improved asthma control, reduced the number of patients reporting a respiratory tract infection, and lowered the rate of antibiotic courses for respiratory indications. Importantly, azithromycin was generally safe and well tolerated, though diarrhoea was more frequent in users of azithromycin than placebo (34% vs 19%).”

In conclusion:

“…add-on therapy with azithromycin is effective and safe in adult patients with uncontrolled asthma despite treatment with inhaled corticosteroids and long-acting beta agonists.”

Dr. David Hahn, Vindicated at Last!

This isn’t the first time we have heard that azithromycin for asthma could be helpful for hard-to-treat patients. Although it is not yet considered standard treatment, researchers have been reporting potential benefit for more than two decades (Presse Medicale, Feb. 4, 1995).

David Hahn, MD, MS, has been researching the potential infectious nature of asthma for more than 25 years (JAMA, July 10, 1991). For much of that time he was a voice in the wilderness. He discovered that many hard-to-treat patients responded to antibiotic therapy, in particular azithromycin. The research from Australia appears to confirm his approach.

New Research Will Consider Azithromycin for Personalized Treatment of Asthma:

Dr. Hahn recently brought this research proposal to our attention. It is sponsored by PCORI, the Patient-Centered Outcomes Research Institute. This independent nonprofit program aims to empower patients by funding research about problems that matter to patients. The proposed study on asthma will be on individualizing care, including azithromycin along with inhaled corticosteroids. If you have been troubled with asthma exacerbations, even though you use your inhaler as you should, you may want to consider participating. The researchers will be looking for biomarkers indicating infections as well as overall asthma control.

The Benefits & Risks of Azithromycin for Asthma:

Dr. David Hahn explains the pros and cons and a unique once-a-week protocol for azithromycin treatment of hard-to-treat asthma. You can read about it in his book, A Cure for Asthma? What Your Doctor Isn’t Telling You–and Why. It is available at www.PeoplesPharmacy.com.

One reader shared this experience:

“My son was cured of moderate asthma after twelve years of suffering with asthma attacks. Zithromax works.

“My five-year-old grandson is now being treated with Zithromax for asthma. He says he feels like a new person already and his treatment still has a few weeks to go.”

Like any medication, azithromycin can have side effects. People with a particular heart rhythm abnormality (long QT interval) should not take this antibiotic. The Australian study did not include them. It also excluded people with hearing loss, since macrolide antibiotics like azithromycin can make hearing loss worse.

The authors of the AMAZES report conclude:

“…in patients who remain symptomatic on maintenance therapy, we consider that azithromycin is a valuable addition to existing regimens for treating asthma.”
