How Serious is LAM?

Published in Serious Lung Disease 3 mins read

Lymphangioleiomyomatosis (LAM) is a serious, rare, progressive lung disease that primarily affects women, though it can also occur in men. While its severity can vary among individuals, LAM is generally considered a significant health concern due to its potential for serious complications and its impact on lung function and overall quality of life.

LAM causes abnormal smooth muscle-like cells to grow uncontrollably, typically in the lungs, but also in the lymphatic system and kidneys. These cells can form cysts in the lungs, leading to a decline in lung function over time.

Key Aspects of LAM's Seriousness

The seriousness of LAM stems from its chronic, progressive nature and the range of complications it can cause:

  • Progressive Lung Damage: The formation of cysts in the lungs gradually destroys healthy lung tissue, leading to impaired breathing. Over time, this can result in shortness of breath, coughing, and fatigue, which worsen as the disease progresses.
  • Serious Complications: LAM can lead to acute and life-threatening complications. One of the most common and serious is a collapsed lung, known medically as pneumothorax.
    • Collapsed Lung (Pneumothorax): This occurs when one of the fragile cysts in the lung bursts, allowing air to leak from the lung into the chest cavity. This change in air pressure can cause the lung to collapse. While a partial collapse might sometimes reinflate on its own in mild cases, a significant collapse often requires medical intervention to remove the air and allow the lung to re-expand.
    • Chylothorax: The abnormal cells can also block lymphatic vessels, leading to a build-up of lymphatic fluid (chyle) in the chest cavity, abdomen, or around the heart.
    • Kidney Tumors (Angiomyolipomas): Many individuals with LAM develop benign tumors in their kidneys called angiomyolipomas (AMLs). While usually not cancerous, these can grow large and, in some cases, lead to bleeding, requiring intervention.
  • Impact on Quality of Life: The chronic symptoms and potential for acute complications can significantly affect a person's ability to perform daily activities, exercise, and work, impacting their independence and well-being.
  • Need for Advanced Treatment: In advanced stages, when lung function is severely compromised, individuals with LAM may require oxygen therapy or even a lung transplant to manage their condition and improve their breathing.

Managing LAM

While LAM is serious, early diagnosis and ongoing management are crucial. Treatment strategies focus on slowing disease progression, managing symptoms, and preventing complications. These can include:

  • Medications such as sirolimus (rapamycin) to inhibit cell growth.
  • Procedures to address collapsed lungs or fluid accumulation.
  • Oxygen therapy to support breathing.
  • Regular monitoring of lung function and kidney health.
