Lung Involvement in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organs and tissues in the body. While the most common manifestations of SLE involve the skin, joints, and kidneys, lung involvement is also frequently observed in patients with this condition.

Lung involvement in SLE can take various forms, with the most common being pleuritis and pneumonitis. Pleuritis refers to inflammation of the lining surrounding the lungs, known as the pleura, while pneumonitis involves inflammation of the lung tissue itself. These conditions can cause significant respiratory symptoms and discomfort for patients.

Common symptoms of lung involvement in SLE include chest pain, shortness of breath, coughing, and occasionally, the production of blood-tinged sputum. These symptoms can be similar to those seen in other respiratory conditions, making it essential for physicians to consider SLE as a potential underlying cause.

1. Pleuritis: Pleuritis is the most frequent pulmonary manifestation of SLE, affecting up to 50% of patients. It typically presents with sharp chest pain, aggravated by deep breathing or coughing. The pain may be localized to one side of the chest or may be felt on both sides. Pleuritis is often accompanied by pleural effusion, which is the accumulation of fluid in the pleural space.
2. Pneumonitis: Pneumonitis is less common but can still occur in patients with SLE. It is characterized by inflammation of lung tissue, leading to symptoms such as shortness of breath, cough, and fever. Pneumonitis can sometimes progress to more severe respiratory complications, including acute respiratory distress syndrome (ARDS).

It is important to note that lung involvement in SLE can be detected through various diagnostic tests, including chest X-rays, computed tomography (CT) scans, and pulmonary function tests. These investigations help identify the presence and extent of inflammation in the lungs, guiding the appropriate management strategies.

Lung involvement in SLE is often managed by treating the underlying autoimmune disease. This may involve the use of immunosuppressive medications, such as corticosteroids and disease-modifying antirheumatic drugs (DMARDs), to reduce inflammation and control symptoms. Additionally, supportive measures such as pain management and respiratory physiotherapy may be employed to improve the patient's quality of life.

In conclusion, lung involvement in systemic lupus erythematosus can manifest as pleuritis or pneumonitis, leading to respiratory symptoms and discomfort. Early recognition and appropriate management are crucial to prevent complications and promote optimal patient outcomes.
