RATIONALE Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive fibrosing interstitial pneumonia. The pathogenicity of IPF has been widely investigated but still remains to be clarified. Efferocytosis, the specialized recognition and ingestion of apoptotic cells by phagocytes, is essential for the resolution of inflammation in the lungs and repair of injured tissues. Impaired efferocyto...

To better understand immune mechanisms involved in onset of cytomegalovirus pneumonia, we initially examined the replication of a low virulence strain of mouse cytomegalovirus (MCMV) in nude and BALB/c mice infected by intranasal inoculation. MCMV was detected by plaque assay in the salivary glands of nude mice from days 3 to 16, and in those of BALB/c mice from days 7 to 11. Nude mice became i...

BACKGROUND Anti-glycyl-tRNA synthetase (anti-EJ) antibody is occasionally positive in patients with interstitial lung disease (ILD). We aimed to define the clinical, radiological and pathological features of patients with anti-EJ antibody-positive ILD (EJ-ILD). METHODS We retrospectively analyzed the medical records of 12 consecutive patients with EJ-ILD who underwent surgical lung biopsy. ...

BACKGROUND Undifferentiated connective tissue disease (UCTD) involves conditions characterized by both having symptoms of connective tissue disease (CTD) and autoantibodies but not fulfilling the criteria of a specific CTD. The frequency or prognosis of the usual interstitial pneumonia (UIP) pattern in UCTD is unknown, which may be confused with idiopathic pulmonary fibrosis (IPF). This study a...

Human cytomegalovirus (CMV) is the most common cause of congenital and perinatal infections throughout the world. Chlamydia trachomatis during pregnancy also cause a wide variety of perinatal complications and neonatal pneumonia. We report a case of neonatal pneumonia caused by intrauterine dual infection with CMV and C. trachomatis. A two-day-old term infant was presented with tachypnea. His c...

Dialysis-related amyloidosis (DRA) is one of the most important complications in long-term dialysis patients. Pulmonary involvement in patients with DRA has been rarely described, and lung radiographic findings have not yet been reported. The most common chronic lung disease process in chronic dialysis patients is interstitial fibrosis. This is the first case report of DRA presenting in the lun...

Among the idiopathic interstitial pneumonias, the two entities-idiopathic pulmonary fibrosis (IPF) characterised by the presence of the usual interstitial pneumonia pattern of histopathology (IPF/UIP) and non-specific interstitial pneumonia (NSIP; same nomenclature for the histopathological pattern and idiopathic disease) - have provoked considerable debate. IPF/UIP and NSIP closely mimic each ...

Rheumatoid arthritis (RA) affects approximately 1% of the US population frequently has extra-articular manifestations. Most compartments of the lung are susceptible to disease. Interstitial lung disease (ILD) and airways disease are the most common forms of RA-related lung disease. RA-ILD carries the worst prognosis and most often manifests in a histologic pattern of usual interstitial pneumoni...

As the authors describe, the initial evidence that pulmonary fibrosis may have a genetic basis emerged from case reports and case series that reported multiple cases of idiopathic interstitial pneumonias (IIPs) clustering in families [2–6]. The epidemiology indicates that within families containing two or more cases of IIP (familial interstitial pneumonia) the development of familial interstiti...
