OBJECTIVE: To identify the clinical characteristics of diffuse alveolar hemorrhage (DAH) compared to other types of acute diffuse lung infiltration in SLE patients, and the factors associated with mortality in these patients. METHODS: We studied a retrospective cohort including SLE patients with acute diffuse lung infiltration on thoracic CT between January 2004 and August 2014. We divided them into 2 groups, a DAH and a non-DAH group, and compared the clinical characteristics and outcomes in the 2 groups...

A relationship between antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and complement has been shown, and complement has an important role in the pathogenesis of AAV. The clinical characteristics of AAV with hypocomplementemia still remain unclear.We conducted an observational study of 81 patients with AAV (median onset age 71 years; 58% female). Using medical records, we analyzed the patients' baseline variables, laboratory data, clinical symptoms, and therapeutic outcomes after treatments including episodes of relapses, initiation of dialysis, and death...

Henoch-Schonlein purpura (HSP) is the most common vasculitis in children. Vasculitic processes can involve the lung. Although diffuse alveolar hemorrhage may be seen as one of the manifestation of HSP, it is not a frequent presentation. Here we reported the case of a 10-year-old girl with HSP nephritis who developed pulmonary hemorrhage. The patient was treated successfully with intravenous methylprednisolone. A review of the literature revealed that young age may be a good prognostic sign and that immunosuppressive drugs and supportive management are essential in the treatment...

Diffuse alveolar hemorrhage is a potentially fatal pulmonary disease syndrome that affects individuals with hematological and nonhematological malignancies. The range of inciting factors is wide for this syndrome and includes thrombocytopenia, underlying infection, coagulopathy, and the frequent use of anticoagulants, given the high incidence of venous thrombosis in this population. Dyspnea, fever, and cough are commonly presenting symptoms. However, clinical manifestations can be variable. Obvious bleeding (hemoptysis) is not always present and can pose a potential diagnostic challenge...

The main clinical manifestations of wild-type transthyretin (TTR)-related amyloidosis are progressive heart failure and neuropathy. There have been some reports on cerebral hemorrhage due to cerebral amyloid angiopathy in patients with TTR-related amyloidosis, but little is known about the vascular involvement in other organs. A 77-year-old woman experienced heart failure and was admitted for deteriorating heart failure status. Echocardiography showed diffuse hypokinesis of the left ventricle with biventricular wall thickness...

Cocaine is one of the most commonly abused drugs in the United States. Ingestion of cocaine may result in a wide array of disease processes due to its stimulant properties, contaminants, or to downstream effects, such as myo- cardial infarction, stroke, or cardiac arrest. Pulmonary complaints are common in patients seeking treatment for cocaine-associated medical problems and include acute eosinophilic pneumonia, pneumothorax, pneumomediastium, diffuse alveolar hemorrhage (DAH), pulmonary hypertension and granulomatosis...

BACKGROUND: Diffuse alveolar hemorrhage (DAH) is a devastating clinical syndrome characterized by a falling hematocrit, respiratory insufficiency, and radiographic evidence of pulmonary infiltrates. Literature regarding management of DAH in childhood-onset SLE (cSLE) is limited. METHODS: We reviewed the presentation, management, and outcome of DAH in a pediatric tertiary medical center with one of the largest cSLE cohorts in North America. During a 10 year period 7 of 410 children with cSLE had DAH...

Numerous adverse effects follow anabolic agent abuse. Pulmonary hemorrhage is not considered one of them. We present two cases of young male bodybuilders who developed diffuse alveolar bleeding as a result of anabolic steroid abuse. Diffuse alveolar hemorrhage associated with anabolic agent abuse has not been described previously in the literature. Both patients developed acute dyspnea and hemoptysis with consistent radiological findings. In both cases symptoms promptly resolved with cessation of exposure and no medical intervention was required and no signs of persistent lung damage were seen...

BACKGROUND: The diffuse alveolar hemorrhage (DAH) syndrome is a life-threatening pulmonary complication related to systemic vasculitides, posthematopoietic stem cell transplantation, drugs, or toxins. Once DAH develops, the mortality rate is as high as 50% to 80%. Initial treatment consists of high-dose steroids and supportive measures, including mechanical ventilation. We present a case series of 6 patients treated with intrapulmonary recombinant factor VIIa (rFVIIa) to treat refractory DAH...

INTRODUCTION: Propylthiouracil (PTU) is commonly used to treat hyperthyroidism and can induce antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Although this is a rare side effect, ANCA-associated vasculitis can progress to severe disease if its diagnosis and treatment are delayed, leading to a poor prognosis. CASE PRESENTATION: A 43-year-old woman with Graves' disease developed pulmonary vasculitis and diffuse alveolar hemorrhage (DAH) associated with ANCA against myeloperoxidase and proteinase-3 that was confirmed by computed tomography (CT) and bronchoscopy and treated with PTU...

Pulmonary renal syndrome is a class of small vessel vasculitides that are characterized by the dual presentation of diffuse alveolar hemorrhage (DAH) and glomerulonephritis. Pulmonary renal syndrome has multiple etiologies, but its development has been rarely reported following infection with group A streptococcus. We present the case of a 36-year-old Native American male who was transferred to our facility due to refractory hypoxic respiratory failure. He had been diagnosed with streptococcal pharyngitis 2 weeks prior to admission...

Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary complication in patients with hematologic malignancies or autoimmune disorders. The current treatment options, which include corticosteroids, transfusions, extracorporeal membrane oxygenation (ECMO), and immunosuppressants, have been limited and largely unsuccessful. Recombinant activated factor VII (rFVIIa) has been successfully administered, either systemically or bronchoscopically, to adults for the treatment of DAH, but there are few data on its use in pediatric patients...

Hemoptysis, a common sign of diffuse alveolar hemorrhage, can be caused by multiple factors, both infectious and noninfectious. A 45-year-old male with hypertension, obstructive sleep apnea, and stage IV pulmonary sarcoidosis with cardiac involvement, presented with a two-month history of cough and acute nonmassive hemoptysis with hypoxia. A chest CT showed ground glass consolidation and interlobular septal thickening, concerning for diffuse alveolar hemorrhage. Flexible bronchoscopy confirmed diffuse alveolar hemorrhage; microbiological analyses of bronchoalveolar washings did not reveal a causative organism...

Both autologous and allogeneic hematopoietic stem cell transplants are important therapeutic options for several benign and malignant disorders. Pulmonary complications, although they have become less frequent, remain a significant cause of morbidity and mortality after hematopoietic stem cell transplant. These complications range from bacterial, fungal, and viral pulmonary infections to noninfectious conditions such as diffuse alveolar hemorrhage and idiopathic pneumonia syndrome. Bronchiolitis obliterans syndrome is the primary chronic pulmonary complication, and treatment of this condition remains challenging...

Antiphospholipid antibody syndrome (APS) is an acquired thrombophilia, caused by autoantibodies to anticardiolipin (aCL), or antibeta 2 glycoprotein I, or the presence of lupus anticoagulant (LA) in plasma. It is characterized by recurrent venous and/or arterial thrombi and/or pregnancy related morbidities. We present the case of a 52-year-old female with long-standing APS, who developed cutaneous vasculitis following a common cold. Most of the cutaneous manifestations of APS have been found to be thrombotic on histopathology without evidence of perivascular inflammation...

Bonchoalveolar lavage is a safe and poorly invasive tool with a great diagnostic value particularly in diffuse infiltrative pulmonary diseases (IPD). In specific instances, it allows for a definite diagnosis (alveolar hemorrhage; alveolar proteinosis, lipidoses, infiltrative malignant diseases, opportunistic infections), obviating the need to perform more invasive diagnostic procedures like video-assisted surgical biopsy. In inflammatory IPD, either idiopathic, diagnostic or associated with inhaled antigens or with collagen vascular diseases for instance, it represents a crucial orientation diagnostic tool, considerably narrowing the spectrum of potential differential diagnosis...

Tissue factor (TF) is a critical mediator of direct acute lung injury (ALI) with global TF deficiency resulting in increased airspace inflammation, alveolar-capillary permeability, and alveolar hemorrhage after intra-tracheal lipopolysaccharide (LPS). In the lung, TF is expressed diffusely on the lung epithelium and intensely on cells of the myeloid lineage. We recently reported that TF on the lung epithelium, but not on myeloid cells, was the major source of TF during intra-tracheal LPS-induced ALI. Because of a growing body of literature demonstrating important pathophysiologic differences between ALI caused by different etiologies, we hypothesized that TF on myeloid cells may have distinct contributions to airspace inflammation and permeability between direct and indirect causes of ALI...
