Empyema in rheumatoid arthritis

Insights

Rheumatoid arthritis (RA) can lead to two types of nontuberculous empyema, sometimes with lung nodules or as large, recurrent infections. Middle-aged men with active RA are particularly susceptible to these serious pleural infections.

Area of Science:

  • Pulmonology
  • Rheumatology
  • Infectious Diseases

Background:

  • Nontuberculous empyema is a serious thoracic infection.
  • Rheumatoid arthritis (RA) is a systemic autoimmune disease affecting joints and potentially other organs.
  • The association between RA and empyema is not well-established, necessitating further investigation.

Purpose of the Study:

  • To investigate the occurrence and characteristics of nontuberculous empyema in patients with rheumatoid arthritis.
  • To review existing literature on the link between RA and empyema.
  • To identify distinct patterns of empyema in RA patients.

Main Methods:

  • Retrospective case review of 67 patients with nontuberculous empyema at Brompton Hospital.
  • Inclusion criteria: absence of malignant disease.
  • Analysis of three identified cases of empyema associated with RA.

Main Results:

  • Three cases of nontuberculous empyema in patients with RA were identified.
  • Two distinct patterns of empyema in RA were observed: 1) associated with nodular pleuropulmonary disease and pyopneumothoraces, and 2) large, recurrent primary empyemas in the presence of active RA.
  • Middle-aged men showed a higher susceptibility, similar to rheumatoid pleural effusions.

Conclusions:

  • Rheumatoid arthritis is associated with specific types of nontuberculous empyema.
  • Empyema in RA patients can manifest with or without pleuropulmonary nodules.
  • Active rheumatoid disease and nodular lung disease are key factors in RA-associated empyema development.

Pleural Effusion I: Introduction

Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

Pleural Effusion II: Symptoms and Management

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Rheumatic Heart Disease IV: Nursing Management

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...
Chronic Obstructive Pulmonary Disease II: Emphysema01:23

Chronic Obstructive Pulmonary Disease II: Emphysema

Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
