How to manage my persistent cough, fatigue, and weight loss?

Question

Hi doctor,

I have had a persistent chronic cough producing thick mucus, progressive shortness of breath, unexplained weight loss of 22 pounds over seven months, drenching night sweats requiring sheet changes multiple times nightly, extreme fatigue, and occasional coughing up blood for fourteen months.

I have bronchiectasis and a previous tuberculosis (TB) infection treated 18 years ago. Despite multiple antibiotic courses for presumed bacterial pneumonia, my symptoms continue worsening. My chest CT shows multiple small nodules, tree-in-bud opacities, and cavitary lesions predominantly in the right middle lobe and lingula, and three separate sputum cultures grew Mycobacterium avium complex (MAC). My concerns are:

What is MAC lung disease?
How did I acquire this?
Is it contagious to my family?
Why me with bronchiectasis?
What is the treatment regimen (Rifampin, Ethambutol, or Azithromycin)?
How long is treatment time?
What are medication side effects?
How often are monitoring tests needed?
What is the cure rate?
Can MAC recur after treatment, and what is my prognosis?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

Based on your description, your symptoms, and test results, your symptoms are typical of Mycobacterium avium complex (MAC) lung disease. It is a slow-growing infection caused by mycobacteria commonly found in water, soil, and dust. It is usually acquired by inhaling the organism from the environment. It is not contagious like tuberculosis, so your family and close contacts are safe.

Since you already have bronchiectasis, your lungs have damaged and widened airways that trap mucus. This creates an environment where these bacteria can grow and persist, which explains why you are more susceptible.

Treatment is long but well-structured. The standard regimen includes three antibiotics: Rifampin, Ethambutol, and Azithromycin. These are taken daily, and therapy continues for at least twelve months after your sputum cultures first become negative. For most patients, the total duration ranges from twelve to eighteen months.

Each medicine has potential side effects. Rifampin may cause orange discoloration of urine and tears and can sometimes affect the liver. Ethambutol may rarely cause changes in color vision, so regular eye examinations are advised. Azithromycin can lead to mild stomach upset in some individuals.

You will need monthly sputum cultures to monitor progress, and blood tests every four to six weeks to ensure your liver and kidneys are tolerating the treatment well. Eye examinations should be done before starting therapy and repeated if any vision changes occur.

Along with medications, daily airway clearance is essential. This includes chest physiotherapy, saline nebulization to clear mucus, and adequate hydration. Make sure to keep your nebulizer clean and use only boiled, cooled water to prevent reinfection. Most patients show significant improvement within a few months, with better energy, reduced cough, and fewer night sweats. Relapse or reinfection can occur, but regular follow-up sputum cultures help detect this early.

I hope this helps you. Please contact us for further queries.
