Large-volume plasma exchange can now be rapidly and safely done using cell separator technology. Significant depletion of immunoglobulins and immune complexes can be achieved by repeated intensive plasmapheresis, but sustained depletion of these constituents requires concomitant immunosuppressive therapy. Plasmapheresis appears to work in some disorders by removing pathogenic antibodies, but other mechanisms of action have been postulated. It is the treatment of choice for thrombotic thrombocytopenic purpura and for the hyperviscosity syndrome due to macroglobulinemia. Apheresis can be useful in the treatment of many other disorders, most notably myasthenia gravis, glomerulonephritis associated with hemoptysis (Goodpasture's syndrome), refractory systemic lupus erythematosus, cryoglobulinemia and immune cytopenic disorders.

Alveolar hemorrhage in mixed cryoglobulinemia associated with hepatitis C virus infection. A 61 year-old woman with type II mixed cryoglobulinemia associated to hepatitis C virus infection has suffered alveolar hemorrhage with multiple pulmonary infiltrates, purpura, glomerulonephritis and polyneuropathy. The respiratory and kidney findings resolved with prednisone, but glomerulonephritis reappeared when interferon-alpha treatment was started and prednisone was reduced. This is the third case of alveolar hemorrhage and glomerulonephritis associated with mixed cryoglobulinemia reported in the literature. The lung involvement in mixed cryoglobulinemia is reviewed. The clinic manifestations (asthma, pleural effusion, hemoptysis or pulmonary fibrosis) are uncommon, but the lung involvement is very frequent if roentgenographic signs and necropsy findings are assessed.

Hepatitis C virus -related mixed cryoglobulinemia is a recognised entity. Renal and pulmonary involvements are severe potential complications of this disease. Alveolar haemorrhage is a form of pulmonary complication. The clinical features of the alveolar haemorrhage can mimic other pulmonary diseases. We present three patients with hepatitis C virus-related mixed cryoglobulinemia associated to pulmonary symptoms that turned to be caused by an alveolar haemorrhage. The first patient was a 71-year old woman that was admitted because of hemoptysis and severe dyspnea that required mechanical ventilation. Although a pneumonia was the initial diagnoses, an alveolar haemorrhage was soon suspected based on the persistence of the pulmonary radiological infiltrates despite an adequate empirical antibiotic treatment and the presence of a progressive anemization. A fibrobronchoscopy, performed 48 hours after treatment was begun, revealed the presence of a 6% of hemosiderophages. The second patient was a 64 years old woman admitted because of dyspnea, vasculitic cutaneous lesions in gluteus and kidney failure. A severe pneumonia was suspected, antibiotic treatment was started and again the patient needed mechanical ventilation. The fibrobronchoscopy demonstrated the existence of a 60% of hemosiderophages. The third case describes a 67 year old woman that complained of fever, dyspnea and right chest pain. Similarly to the previous cases a severe pneumonia was the initial diagnoses, the patient needed to be transferred to the intensive care unit and mechanical ventilation was finally required. The fibrobronchoscopy showed remains of blood suggestive of an alveolar haemorrhage.

Anti-neutrophil cytoplasmic antibody-associated vasculitis and Goodpasture's glomerular basement membrane disease are the most common causes of diffuse alveolar hemorrhage, a life-threatening disease. Systemic lupus erythematosus and the antiphospholipid syndrome are also causes of alveolar hemorrhage. We retrospectively reviewed 15 cases of diffuse alveolar hemorrhage (DAH) associated with renal diseases. Diagnosis of DAH was based on the presence of bloody bronchoalveolar lavage fluid. There were three men and 12 women, with a mean age of 50.5 years (extremes: 24-74 years). Proteinuria and hematuria were observed, respectively, in 15 and 14 cases. Six patients revealed arterial hypertension. Crescentic glomerulonephritis was diagnosed with kidney biopsies in ten cases. The etiology of renal disease was microscopic polyangiitis (MPA) in seven cases, Wegener disease in four cases, systemic lupus erythematous in one case, cryoglobulinemia in one case, myeloma in one case and propyl-thiouracil-induced MPA in one case. Hemoptysis occurred in 14 cases. The mean serum level of hemoglobin was 7.1 g/dL (5.1-10 g/dL). The mean serum creatinine concentration was 7.07 mg/dL (2.4-13.7 mg/dL). Gas exchange was severely compromised, with an oxygenation index <80 mmHg in 14 patients and <60 mmHg in seven patients. Bronchoalveolar lavage was performed in 11 cases, and had positive findings for hemorrhage in all. Methylprednisolone pulses and cyclophosphamide were used in 14 patients. Plasmapheresis was performed in three cases. One patient received cycles of Dexamethasome-Melphalan. Three patients died as a result of DAH. The mortality rate in our study was 20%.
