We describe the case of a 73-year-old man who experienced dry cough and exertional dyspnea after dabigatran administration. Chest radiographs revealed the development of bilateral consolidative and ground glass opacity, and transbronchial lung biopsy showed organized materials in the alveolar spaces with moderate inflammatory infiltrate and focal fibrosis. Lung opacity gradually disappeared after discontinuing dabigatran. To date, there has been only one report regarding dabigatran-induced lung injury, except for alveolar hemorrhage and eosinophilic pneumonia...

Background: Multi-organ failure (MOF) following trauma remains a significant cause of morbidity and mortality related to a poorly understood abnormal inflammatory response. We characterized the inflammatory response in a non-human primate soft tissue injury and closed abdomen hemorrhage and sepsis model developed to assess realistic injury patterns and induce MOF. Methods: Adult male Mauritan Cynomolgus Macaques underwent laparoscopy to create a cecal perforation and non-anatomic liver resection along with a full-thickness flank soft tissue injury...

It is well known that some disorders can cause concomitant kidney dysfunction with lung involvement. These syndromes, characterized by the simultaneous presence of intra-alveolar hemorrhage and acute glomerulonephritis, are caused by numerous and variable disorders. The most frequent are the antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis and Goodpasture syndrome. A quick discerning of the underlying causes and initiation of adequate treatment is crucial to prevent acute respiratory failure and irreversible loss of renal function...

A 65-year-old man was diagnosed with granulomatosis with polyangiitis (GPA) based on the detection of high MPO-ANCA, vasculitis and granulomas in a lung biopsy specimen and crescentic glomerulonephritis in a kidney biopsy specimen. Soon after the initiation of intravenous methylprednisolone pulse therapy (mPSL pulse) and intravenous cyclophosphamide pulse therapy (IVCY), the patient experienced cough and hemoptysis. Based on emerging anemia and bilateral diffuse lung consolidation on computed tomography, we judged that diffuse alveolar hemorrhage (DAH) was complicated by GPA...

BACKGROUND: Hepatic alveolar echinococcosis (HAE) is a severe and common parasitic disease in Tibetan Plateau of China. The infected patients have to move to plain areas to receive treatments due to the poor medical conditions in plateau areas. Our aim was to investigate the application of Enhanced Recovery after Surgery (ERAS) program in perioperative management for HAE patients from Tibet Plateau and the notes for patients with landform changes. MATERIAL AND METHODS: A total of 89 HAE patients from Tibet Plateau (altitude: average of 4500 m) prior received adaptive treatments at the cooperative hospital (altitude: 1500-2000 m) and accepted surgery at plain regions (altitude: 200-400 m)...

BACKGROUND: Despite progress in the current genetic manipulation of donor pigs, most non-human primates were lost within a day of receiving porcine lung transplants. We previously reported that carbon monoxide (CO) treatment improved pulmonary function in an allogeneic lung transplant (LTx) model using miniature swine. In this study, we evaluated whether the perioperative treatment with low-dose inhalation of CO has beneficial effects on porcine lung xenografts in cynomolgus monkeys (cynos)...

Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is usually a multisystem disorder, and pulmonary renal syndrome is a common presentation. Patients with AAV are less likely to experience relapse when they progress to end-stage renal disease (ESRD). We report a rare case of diffuse alveolar hemorrhage (DAH) in relapsing AAV after eight years of haemodialysis. A 58-year-old woman was admitted to our hospital with the chief complaints of dyspnea and hemoptysis accompanied by anemia, fever, fatigue, and weight loss...

Malaria is a severe disease and kills over 400,000 people each year. Malarial complications are the main cause of death and include cerebral malaria and malaria-associated acute respiratory distress syndrome (MA-ARDS). Despite antimalarial treatment, lethality rates of MA-ARDS are still between 20 and 80%. Patients develop pulmonary edema with hemorrhages and leukocyte extravasation in the lungs. The vascular endothelial growth factor-A (VEGF-A) and the placental growth factor (PlGF) are vascular permeability factors and may be involved in the disruption of the alveolar-capillary membrane, leading to alveolar edema...

IgA vasculitis (IgAV) commonly occurs in young children, who present with a tetrad of purpura, abdominal pain, arthralgia and nephritis. Diffuse alveolar hemorrhage (DAH) is a rare complication of IgAV. We herein report an adult case of IgAV with a presentation of DAH and nephritis (pulmonary renal syndrome, PRS), but without other typical manifestations, such as purpura, abdominal pain and arthralgia. A 33-year-old man presented with hemoptysis and a low-grade fever and was diagnosed to have IgAV based on the results of a renal biopsy...

Diffuse alveolar hemorrhage (DAH) is a rare but potentially fatal complication in systemic lupus erythematosus (SLE). DAH is typically characterized by hemoptysis, dyspnea, new infiltrates on chest x-rays or CT-scans and a drop in hemoglobin. DAH is seen in less than 2% of patients with SLE and carries a high acute mortality risk of up to 70-90%. The current treatment of DAH is high-dose intravenous corticosteroids, cyclophosphamide and extensive supportive care. Plasmapheresis is also often considered in the treatment...

BACKGROUND Diffuse alveolar hemorrhage (DAH) is a rare but potentially fatal complication of anticoagulant or antiplatelet therapy. Bivalirudin is a specific and reversible direct thrombin inhibitor (DTI). CASE REPORT We report a case of severe DAH, possibly related to bivalirudin use, in a 61-year-old patient undergoing coronary intervention. The patient had presented with an out-of-hospital cardiac arrest due to acute ST elevation myocardial infarction (STEMI). During the coronary intervention, shortly after receiving bivalirudin, the patient started having frank bleeding from the endotracheal tube and developed hemodynamic compromise...

We describe here the case of a 73-year-old woman who presented a recurrent macular rash, acute respiratory distress, and hemoptysis. Chest CT scan showed diffuse ground-glass opacities that were suggestive of alveolar hemorrhage. With the development of severe acute kidney injury and nephrotic-range proteinuria (creatininemia 2.6 from 1.9 mg/dL with overt proteinuria 34 from 2.1 g/g creat), a kidney-lung syndrome was evoked. Skin biopsy revealed leukocytoclastic vasculitis with IgA deposits. Blood tests showed an increased IgA level...

A previously healthy 55-year-old man with H1N1 influenza A presented with severe respiratory failure and cardiac arrest. Following the return of spontaneous circulation, venovenous extracorporeal membrane oxygenation was required to maintain oxygenation. On day 2, bronchoscopy revealed a bloody bronchial cast obstructing the right main bronchus. A pathological examination revealed that it was composed of intrabronchial and intra-alveolar hemorrhagic tissue. Unfortunately, the patient died due to severe brain ischemia; a subsequent autopsy revealed marked alveolar hemorrhage...
