Pseudomonas aeruginosa Induced Lung Injury Model
Published on: October 29, 2014
Summary
This study details the first documented case of severe D-penicillamine-induced pneumonitis in a rheumatoid arthritis patient. Histological analysis revealed significant lung damage, prompting a review of the drug
Area of Science:
- Pulmonology
- Rheumatology
- Pharmacology
Background:
- Rheumatoid arthritis (RA) treatment often involves disease-modifying antirheumatic drugs (DMARDs).
- D-penicillamine is a DMARD used for RA, known for potential adverse effects.
- Gold salts are an alternative RA treatment, and intolerance to gold was noted in this patient.
Observation:
- A 73-year-old woman with RA and prior gold intolerance developed severe respiratory symptoms.
- Histopathological examination of lung tissue showed extensive interstitial and alveolar damage.
- The observed lung damage pattern was similar to that seen with certain chemotherapy agents.
Findings:
- This case represents the first histological description of severe D-penicillamine-induced pneumonitis.
- The pathological findings indicate significant drug-induced lung injury.
- The patient's history of gold intolerance may be relevant to drug-induced hypersensitivity.
Implications:
- This case highlights the potential for severe pulmonary toxicity with D-penicillamine.
- Understanding the pathogenetic pathways of D-penicillamine pneumonitis is crucial for patient management.
- Careful monitoring and consideration of alternative treatments are recommended for patients on D-penicillamine, especially those with a history of drug intolerance.

Pneumonia I: Introduction
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.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pneumonia III: Complications and Assessment
Pneumonia poses the potential for numerous complications that warrant consideration. These complications include the following:
Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
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.
Pneumonia I: Introduction
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...
