Summary
Purulent pericarditis is rare but can be caused by Haemophilus parainfluenzae. This case highlights the importance of considering this pathogen in patients with pericardial tamponade, leading to successful antibiotic treatment.
Area of Science:
- Infectious Diseases
- Cardiology
- Microbiology
Background:
- Bacterial pericarditis is uncommon in the antibiotic era.
- Common causes include Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae.
- An increasing trend of Haemophilus parainfluenzae infections, including rare endocarditis cases, has been noted.
Observation:
- A 62-year-old woman presented with symptoms of pericardial tamponade following an upper respiratory tract infection.
- Initial pericardiocentesis provided temporary hemodynamic stability.
- Recurrent pericardial tamponade necessitated a pericardial window creation within 24 hours.
Findings:
- Cultures of pericardial fluid identified Haemophilus parainfluenzae as the causative agent.
- The patient received Levofloxacin therapy.
- The patient recovered following appropriate antibiotic treatment.
Implications:
- Haemophilus parainfluenzae should be considered in the differential diagnosis of purulent pericarditis.
- Prompt diagnosis and targeted antibiotic therapy are crucial for patient survival.
- This case represents the first reported instance of purulent pericarditis caused by H. parainfluenzae.

758
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

01:29Pneumonia I: Introduction
24
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

01:30Pneumonia I: Introduction
1.5K
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.

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...

01:25Pericarditis IV: Nursing Management
640
Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.
