Systemic vasculitides are potentially life-threatening diseases. Early and appropriate diagnosis based on case history, clinico-pathological features, and laboratory parameters, such as the presence of anti-neutrophil cytoplasmic antibodies (ANCA), is crucial for starting appropriate and, often, life-saving therapeutic measures. We report a 50-year-old female patient who presented with fever, arthralgias and hemoptysis. Skin signs included disseminated hemorrhagic pustules, ulcerations of oral and genital mucosa, subcutaneous nodules on arms and legs, and a pyoderma gangrenosum-like lesion on the right leg. Laboratory investigations revealed a peripheral eosinophilia and a positive cANCA titer. Histopathologic analysis of various biopsy specimens showed a granulomatous vasculitis in the subcutis, a nongranulomatous vasculitis with massive eosinophil infiltration in the lungs, and a segmental, necrotizing glomerulonephritis in the kidneys. Differential diagnosis included Wegener's granulomatosis, microscopic polyangiitis (MPA) and Churg-Strauss syndrome. MPA was diagnosed based on clinical and histopathological criteria. An interesting feature of this case was marked peripheral and tissue eosinophilia. Therapy consisted of cyclophosphamide and methylprednisolone. The patient went into a long-lasting clinical remission one month after starting therapy.

An 86-year-old woman was admitted with hemoptysis and rapid deterioration of renal function. Renal biopsy disclosed necrotizing crescentic glomerulonephritis. Based on positivity for serum myeloperoxidase antineutrophil cytoplasmic autoantibody (MPO-ANCA), MPO-ANCA-associated glomerulonephritis was diagnosed. Steroid pulse therapy was performed, but the patient died after the second course. Autopsy revealed renal vasculitis with fibrinoid necrosis extending to the level of the arcuate arteries. Vasculitis was also observed in the liver, adrenal gland, uterus, and spleen, suggesting the presence of microscopic polyarteritis. This case demonstrates the broad spectrum of MPO-ANCA-positive vasculitis and suggests the need for a more effective therapy suitable for very elderly patients.

Goodpasture syndrome (GS) is an autoimmune disorder characterized by the association of pulmonary hemorrhage and rapidly progressive glomerulonephritis. The pathogenesis of GS is still unknown, but was shown to be the result that antibodies directed against glomerular basement membrane (GBM) antigens could injure both glomerular and pulmonary alveolar basement membrane. And membranous glomerulonephritis (MGN) is a glomerular disease characterized by epimembranous immune deposits and basement membrane thickening. MGN typically presents with the onset of nephrotic syndrome, but it often presents with only asymptomatic proteinuria. We reported an autopsy case of GS preceded with MGN. A 70-year-old man was admitted to our hospital with acute renal failure in May 2, 1996. Percutaneous renal biopsy demonstrated a crescentic glomerulonephritis associated with MGN and linear immunofluorescent staining of the basement membrane with antibodies to IgG. Two weeks later on admission he began to develop slight hemoptysis and chest X-ray showed pulmonary hemorrhage, Furthermore, his serum anti-GBM antibodies titer was very high. He was diagnosed as GS associated with MGN and treated with plasma exchange, glucocorticoid, and cyclophosphamide. Though his symptom was improved for intensive support, he suddenly died on June 22. Autopsied lungs showed focal pulmonary hemorrhage, but were not considered to be life-threatening. The cause of the death remained unclear.

A 55-year-old man was admitted to our hospital with of hemoptysis, progression of anemia and renal failure in February, 1996. Idiopathic interstitial pneumonia had been diagnosed and he had been followed at a regional hospital since 1988. On the third day after admission, he suffered from sudden and massive hemoptysis. Goodpasture's syndrome was diagnosed because anti-GBM antibody was detected in serum. A high titer of MPO-ANCA was also recognized simultaneously. Steroid pulse therapy, immunosuppressive therapy, and plasmapheresis were begun, but he died on the 28th hospital day because of severe hypoxemia and multi-organ failure. Histological examination after autopsy revealed crescentic glomerulonephritis with linear deposition of IgG in the glomerular capillary wall, and interstitial pneumonia accompanied by massive alveolar hemorrhage. It was suggested that in this patient, not only anti-GBM antibody but also circulating MPO-ANCA might have participated in the progression of the crescentic glomerulonephritis and alveolar hemorrhage observed in Goodpasture's syndrome.

We report the occurrence of spontaneous splenic hemorrhage in a patient with Wegener's granulomatosis. Pulmonary infiltrates, hemoptysis, and crescentic glomerulonephritis were accompanied by a progressive splenic enlargement with minimal abdominal symptoms. Magnetic resonance imaging was particularly helpful. The spleen was removed by minimally invasive endoscopic surgery. Subcapsular hemorrhage had occurred because of splenic vasculitis. Postoperatively, a remission was achieved by a combination of high-dose corticosteroids and cyclophosphamide.

The clinical course of 15 patients with Wegener's granulomatosis (WG) and eight patients with microscopic polyangiitis (MPA) from one nephrological clinical center is presented for the period from 1984 to 1993, when testing for antineutrophil cytoplasmic antibodies (ANCA) was gradually introduced into routine clinical practice. We found a high degree of prolonged time periods with symptoms attributable to WG or MPA until the specific diagnosis was made. Nine patients with WG and one patient with MPA had symptomatic prediagnostic periods of more than three years, which extended in one case up to twenty years. In these prediagnostic periods, often even severe flares of vasculitic activity resulted in spontaneous remission without immunosuppressive therapy. One patient on chronic dialysis for four months because of rapidly progressive glomerulonephritis, experienced sufficient spontaneous regain of residual renal function to stay off dialysis for 6 years. Despite a high amount of spontaneous recovery, recurrent flares of disease eventually led to death in those cases without sufficient immunosuppressive therapy. Contrary to long courses of disease, one patient with WG had a fulminate exacerbation of disease with lethal hemoptysis after a prediagnostic period of only three months. Renal disease, respiratory and other symptoms did not occur sequentially, but each could precede the other. We conclude in agreement with published former experience, that WG and MPA show a highly variable spontaneous disease course, that requires extended observational periods for evaluating maintenance therapies.

A 75-yr-old male hospitalized for vascular purpura with joint pain had a medical history of polymyalgia rheumatica. A generalized oedematous syndrome occurred and the patient also presented with haemoptysis and complained of transient paraesthesia of the hands and feet. Renal biopsy showed lesions of focal segmental proliferative glomerulonephritis associated with a few cellular crescents. Lung biopsy showed small-cell neuroendocrine carcinoma. After the first course of chemotherapy signs of vasculitis disappeared. Small-cell neuroendocrine carcinomas, which represent 25% of all lung cancers, have numerous paraneoplastic (especially neurological) extrapulmonary manifestations. Disseminated vasculitis has never been described with this type of cancer, whereas nonsmall-cell carcinomas are associated essentially with cutaneous vasculitis or purpura rheumatica. In the case reported here, anticancer chemotherapy allowed vasculitic manifestations to be treated.

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.

A 34-year-old Japanese male was admitted to Okayama University Hospital with severe hypertension, rapidly progressive renal failure, blurred vision, dyspnea and hemoptysis. Clinical diagnosis of malignant hypertension was given and antihypertensive therapy and hemodialysis were immediately started. Renal biopsy was performed on the sixth day in hospital to examine the underlying disease, such as microscopic form of polyarteritis, since the complaint of hemoptysis and pulmonary alveolar hemorrhage was noted by computed tomography of the lungs. Typical pathological changes of malignant hypertension, i.e. fibrinoid necrosis of the afferent arterioles and proliferative endoarteritis at the interlobular arteries were observed. There was no evidence of active necrotizing glomerulonephritis and crescent formation. Renal function was gradually recovered and pulmonary hemorrhage completely disappeared by treatment with antihypertensive agents. The authors report a case of malignant hypertension with a rare complication of pulmonary alveolar hemorrhage and speculate that it may be related to vascular injuries at the alveolar capillary level caused by malignant hypertension.

A 63-year-old man was referred to our hospital for rapid deterioration of his renal function. He had worked as a metal founder for more than 40 years, and had been diagnosed as having silicosis. Laboratory data on admission showed severe anemia, thrombocytopenia, and end-stage renal failure (BUN 88.8 mg/dl, serum creatinine 9.0 mg/dl). Myeloperoxidase anti-neutrophil cytoplasmic antibody(MPO-ANCA) was also detected in his sera. On the next day after admission, he complained of sudden dyspnea and hemoptysis. Mechanical ventilation with pure oxygen was insufficient to improve hypoxia without concomitant use of percutaneous cardio-pulmonary support(PCPS) and continuous hemofiltration(CHF). We diagnosed his condition as MPO-ANCA-associated rapidly progressive glomerulonephritis with diffuse alveolar hemorrhage. Treatment with plasmapheresis, pulse methylprednisolone and pulse cyclophosphamide effectively improved his hemoptysis as well as chest X-ray findings and blood gas analysis. However on his later clinical course, he was complicated with superimposed complex infection and passed away. Autopsy findings showed crescentic glomerulonephritis in the kidneys and silica nodules in the lungs. Recently it has been postulated that some relationship exists between ANCA-associated(especially MPO-ANCA-associated) glomerulonephritis and silica exposure. The reported cases of glomerulonephritis in the patients with silica exposure showed a rapidly progressive clinical course and pauci-immune necrotizing crescentic glomerulonephritis in their histology. Gregorini et al. reported that 12 of 37 (32%) male patients with RPGN had either silicosis or significant silica exposure, and 7 of 8 patients examined were ANCA-positive(6 of 7 were MPO-ANCA-positive). Therefore silica seems to cause glomerulonephritis by disrupting the immune response. Including this case mentioned above, we have experienced 10 cases of MPO-ANCA-associated glomerulonephritis, at least 3 cases out of which had suffered from silicosis in the past(30%). These results indicate that silicosis should be considered a relevant pathogen of MPO-ANCA-associated glomerulonephritis beyond the race.
