We present two patients who developed subacute diffuse infiltrative lung disease while receiving flecainide for supraventricular arrhythmia. They had bilateral subpleural lung opacities on computed tomography. Bronchoalveolar lavage revealed increased numbers of lymphocytes and eosinophils, and a low CD4/CD8 ratio. Nonspecific interstitial pneumonia was documented by open lung biopsy in patient 1. The outcome was favorable after flecainide withdrawal and prednisone treatment. Drug-induced…

Flecainide-induced pneumonitis: a case report

Clinical and radiological improvement was noted after corticosteroid therapy, but the patient died from septic complications, and flecainide-induced lung injury has rarely been reported in the literature and remains a diagnosis of exclusion.

Patterns of Pulmonary Complications Associated with Sirolimus

The patterns of pulmonary adverse effects associated with sirolimus in 4 renal transplant recipients who developed pulmonary opacities on chest radiograph were studied, which were proved to be noninfectious in origin.

An unusual presentation of pulmonary lymphoma: When diffuse ground glass opacities can mean anything.

The case of a 63-year-old Caucasian male who developed severe acute respiratory failure and diffuse ground glass opacities (GGO) on chest computerized tomography is presented and P-DLBCL should be considered among the many differential diagnoses of diffuse GGO.

Influenza A virus associated with non-specific interstitial pneumonitis: First case report

Open lung biopsy was performed and histopathology consistent with cellular non-specific interstitial pneumonitis (NSIP), and Prednisone was started for NSIP, and the patient was successfully liberated from MV and was eventually discharged home breathing on room air.

Rifampicin induced pneumonitis or bronchogenic spread of tuberculous empyema through a bronchopleural fistula?

The article by Kunichika et al which describes a probable case of pneumonitis induced by rifampicin needs further clarification, and the authors do not specify the characteristics of the pleural fluid of the patient.

Idiopathic nonspecific interstitial pneumonia: report of an American Thoracic Society project.

Iiopathic NSIP is a distinct clinical entity that occurs mostly in middle-aged women who are never-smokers and the prognosis is very good.

Drug-induced and iatrogenic respiratory disease

Pneumonitis induced by non-cytotoxic agents Amiodarone pulmonary toxicity Eosinophilic pneumoniainduced by drugs Bronchiolitis obliterans organizing pneumonia induced by drugs or radiotherapy.

Atrial arrhythmias in chronic lung disease-associated pulmonary hypertension

Individual approaches are needed to address atrial arrhythmia management during acute episodes of respiratory failure, as there is controversy on the use of rhythm control agents.



Flecainide-associated pneumonitis with acute respiratory failure in a patient with the LEOPARD syndrome

A case of interstitial hypoxaemiant pneumonitis probably related to flecainide in a patient with the LEOPARD syndrome, a rare congenital disorder is described.

Nonspecific interstitial pneumonia. Individualization of a clinicopathologic entity in a series of 12 patients.

Despite its heterogeneity, NSIP deserves to be individualized as an original clinicopathologic entity and should be clearly distinguished from usual interstitial pneumonia, especially because of a better prognosis.

Development of nonspecific interstitial pneumonitis associated with long-term treatment of primary pulmonary hypertension with prostacyclin.

A young woman with primary pulmonary hypertension presented with interstitial lung disease approximately 5 years after successful treatment with IV prostacyclin. The pathology was consistent with

Computed tomography: pathologic correlation in lung disease due to tocainide.

High resolution computed tomography was used to demonstrate the active lung phase of a patient with tocainide pulmonary toxicity and correlated closely with the pathologic findings.

Pulmonary fibrosis associated with tocainide: report of a case with literature review.

Review of the literature revealed other cases with an association between the use of tocainide and the development of pulmonary complications such as pulmonary fibrosis and interstitial pneumonitis, and suggested that clinical improvement occurs when the correct diagnosis is made early and toc Cainide therapy is stopped immediately.

Nonspecific Interstitial Pneumonia/Fibrosis: Histologic Features and Clinical Significance

Sixty-four cases of interstitial pneumonia were identified that could not be classified into one of three main categories of idiopathic interstitial pneumonia. These cases, descriptively termed

Idiopathic pulmonary fibrosis: clinical relevance of pathologic classification.

This work states that Idiopathic Pulmonary Fibrosis is a Specific Disease or a Histologic Manifestation of Many Diseases and AIP and UIP are Significance of NSIP.

Drugs that may injure the respiratory system.

The preparation of a table listing most drugs capable of injuring the respiratory system was appropriate and designed to provide the information currently available on such drugs in a readily accessible form.
