Acute lung injury (ALI) is a serious disease with high morbidity and mortality rate. Although there are effective strategies for treatment of ALI; a widely accepted specific pharmacotherapy has not yet established. Zerumbone, the major active phytochemical compound from Zingiber zerumbet Smith, exhibits various beneficial biological and pharmacological activities, such as antioxidation, anti-inflammation, immunomodulation, and anti-cancer. We aimed to study the potential protective effects and mechanisms of zerumbone in mouse model of lipopolysaccharide (LPS)-induced ALI...

BACKGROUND: Subarachnoid hemorrhage (SAH) can lead to neurogenic pulmonary edema (NPE), and chylomicron metabolism may be altered unfavorably in acute lung injury. This study aimed to investigate the possible effect of NPE on the development of coronary fat embolism. METHODS: This study was conducted on 27 rabbits, 5 of which were used as the control (n=5). Experimental SAH was induced in 15 of the animals by injecting homologous blood into the cisterna magna, and the remaining 7 animals were administered only isotonic saline solution (Sham, n=7) in the same manner under general anesthesia...

The mammalian target of rapamycin inhibitor sirolimus was introduced into clinical transplant practice in 1999. Dose-related myelosuppression and hyper lipidemia are the most common adverse effects. Pulmonary toxicity has been reported since 2004 and can cause interstitial pneumonitis, organizing pneumonia, and alveolar hemorrhage. Moreover, it can occasionally induce posterior reversible encephalopathy syndrome, as documented in scarce reports. To our knowledge; this is the 1st report of combined posterior reversible encephalopathy syndrome and lymphocytic pneumonitis to be induced by sirolimus...

OBJECTIVE: Diffuse alveolar hemorrhage (DAH) in lupus patients is >50% fatal. The cause is unknown. The pathogenesis of DAH in C57BL/6 mice with pristane-induced lupus, a model of human lupus-associated DAH, was examined. METHODS: Clinical/pathological and immunological manifestations DAH in pristane-lupus were compared with human DAH. Tissue distribution of pristane was examined by mass spectrometry. Cell types responsible for disease were determined by in vivo depletion using clodronate liposomes (CloLip) and anti-neutrophil monoclonal antibodies (GR1)...

Pulmonary alveolar proteinosis (PAP) is classified as autoimmune, secondary, or genetic. We herein describe a 69-year-old man with autoimmune PAP, simultaneously diagnosed with myeloproliferative neoplasm (MPN). Two years after the diagnosis, the MPN progressed to acute myeloid leukemia, and the patient died from an alveolar hemorrhage during remission induction chemotherapy. Throughout the clinical course, no progression of PAP was observed, despite the progression to leukemia. There are few reports of autoimmune PAP with hematological malignancy, and this case demonstrated that an evaluation for GM-CSF autoantibodies is important for distinguishing the autoimmune and secondary forms of PAP, even if the patient has hematological malignancy...

Diffuse alveolar hemorrhage (DAH) is a life-threatening complication that occurs in association with various diseases including coagulation disorders. In rare cases, it is caused by hemophilia. A 48-year-old man was admitted to our hospital for a third time due to DAH. Although the cause of DAH could not be identified by bronchoscopy or laboratory tests, a good response to corticosteroids suggested idiopathic DAH with pulmonary capillaritis. The patient was diagnosed with hemophilia B based on the results of a detailed inquiry, a mildly prolonged activated partial thromboplastin time, and low factor IX activity...

C5-deficient mice usually present moderate neutrophil activation during the initiation phase of acute inflammation. Conversely, C5a receptor (C5aR)-deficient mice show unusually excessive activation of neutrophils. We identified the ribosomal protein S19 (RP S19) polymer, which is cross-linked at Lys122 and Gln137 by transglutaminases in apoptotic neutrophils, as a second C5aR ligand during the resolution phase of acute inflammation. The RP S19 polymer promotes apoptosis via the neutrophil C5aR and phagocytosis via the macrophage C5aR...

There is a wide spectrum of severities in patients with pulmonary bleeding with a range from mild haemoptysis to severe bleeding with an acute risk of asphyxiation. For the management of acute pulmonary haemorrhage, it is essential to identify the underlying cause in order to initiate a target-oriented or causal therapy. The most common causes of localized pulmonary bleeding are lung cancer as well as infections, anticoagulant therapy or bronchiectasis. Diffuse alveolar haemorrhage is mostly due to pulmonary vasculitis or connective tissue disease, but may also occur in pulmonary metastasis, congestive heart failure, coagulation disorders and from many other causes...

Anti-neutrophil cytoplasmic antibodies (ANCA) appear to play an important role in the pathogenesis of ANCA-associated vasculitis (AAV). However, ANCA alone are not sufficient to generate disease, and some evidence suggests that infectious triggers may serve as inciting events for AAV disease activity. Antibodies of the immunoglobulin (Ig)M isotype often serve as markers of recent infection, and IgM ANCA have been identified previously in patients with AAV, although the frequency and clinical relevance of IgM ANCA is not well established...

Granulomatosis with polyangiitis (GPA) is a potentially life-threatening, rare disease. The etiology is unknown. GPA is histomorphologically characterized by extravascular necrotizing granulomatous inflammation and a systemic necrotizing vasculitis of small to medium-sized vessels. Clinically, a pulmonary-renal syndrome with pulmonary infiltrates, alveolar hemorrhage and a rapidly progressive glomerulonephritis is seen in about 80% of the cases with generalized disease. GPA is associated with proteinase 3-specific anti-neutrophil cytoplasmic autoantibodies (PR3-ANCA)...
