We describe two cases (61-year-old female and 71-year-old male) with MPO-ANCA (myeloperoxidase-antineutrophil cytoplasmic antibody) positive who developed severe interstitial pneumonitis. They presented at our hospital with dyspnea and dry cough. The hypoxia and abnormal shadow on chest X-ray led to a diagnosis of interstitial pneumonitis. Serologic studies revealed the high titers of MPO-ANCA in two cases. They were treated with methylprednisolone, immunosuppressant agents and plasma exchange. The pneumonitis and the titers of MPO-ANCA improved on these therapies, The former was introduced continuous hemodialysis therapy and the later continued nephrotic syndrome. These renal damages did not recover, regardless of the reduction of the titers of MPO-ANCA. It is concluded that methylprednisolone pulse therapy, immunosuppressant agents and plasma exchange therapy are useful to interstitial pneumonitis in patient with positive of MPO-ANCA. The measurement of MPO-ANCA is useful to interstitial pneumonitis in patient with positive of MPO-ANCA. The measurement of MPO-ANCA is useful maker of interstitial pneumonitis for unknown causes.

We reported two cases of silicosis exhibiting MPO-ANCA associated disorder. Case 1 was a 69 year-old man with silicosis and chronic interstitial pneumonia. He was admitted because of fever, dry cough, left chest pain, dyspnea and body weight loss. He was diagnosed as acute exacerbation of interstitial pneumonia, pericarditis and gastrointestinal bleeding. Case 2 was a 67 year-old man with silicosis. He repeated attack of fever, hoarseness, dysphagia and headache. The cell counts of cerebrospinal fluid increased and the thickness of cerebellar tent and left dura mater was observed in the brain MRI. Therefore, he was diagnosed as pachymeningitis and neuropathy of cranial nerves. Both cases were complicated by silicosis and the laboratory findings showed high serum levels of P-ANCA, ANA and rheumatoid factor and inflammatory responses, indicating they were suspected vasculitis. The two cases were treated by steroid and immunosuppressive therapy and had good clinical response. Silicosis may affect multiple organ involvement associated with P-ANCA.

We report a case of hepatitis C virus-associated glomerulonephropathy presenting with MPO-ANCA-positive, rapidly progressive glomerulonephritis(RPGN). A 60-year-old woman was admitted to our hospital for evaluation of RPGN. Laboratory evaluation revealed microhematuria, proteinuria(800 mg/day), anemia, renal failure(blood urea nitrogen 27 mg/dl, serum creatinine 2.2 mg/dl), cryoglobulinemia, hypocomplementemia, positive MPO-ANCA(232 EU), and hepatitis C virus infection(GOT 58 IU/l, GPT 38IU/l, HCV-RNA(PCR) 1,200 kcopy/ml, serotype 1). After admission, the patient's renal function and anemia deteriorated rapidly, then prednisolone(30 mg/day) was started. After treatment her renal function gradually improved, then a renal and liver biopsy was performed. The renal biopsy revealed six sclerosing fibrous crescentic glomeruli in twelve glomeruli. Immunofluorescent examination revealed granular deposits of IgG, C3, and fibrinogen along the glomerular basement membrane and mesangial matrix. The pathogenesis of RPGN in this case may relate to the deposition of immune complexes in the glomeruli because immunofluorescent examination was revealed to be the immune-complex type, but not pauci immune type nephritis. Liver histology revealed chronic active hepatitis with mild piecemeal necrosis and did not reveal vasculitis. Although her renal function was improved after treatment with prednisolone, she suffered from pulmonary manifestations(dry cough etc.) on the 120th hospital day. Suddenly she died because of pulmonary hemorrhage on the 180th hospital day. These findings suggest that various HCV-induced immunological abnormalities, such as positive MPO-ANCA, cryoglobulinemia and hypocomplementemia, play an important role in the pathogenesis of this RPGN, although we could not demonstrate deposition within glomeruli of immune complexes containing HCV. The effect of interferon therapy on such immunological abnormalities remains to be documented. Since interferon is known to have immunomodulatory effects, we selected corticosteroid therapy. Future studies need to focus on the optimal treatment strategy for hepatitis C virus-associated glomerulonephritis.

A 51-year-old female was admitted to Nagano Matsushiro General Hospital because of fever, cough and dyspnea on exertion. Her laboratory data revealed leukocytosis with hypereosinophilia, a high erythrocyte sedimentation rate and c-reactive protein. Chest radiography revealed an infiltration shadow with a cavity in the right upper lobe. A lung abscess was diagnosed and antibiotics were administered. Laboratory results showed improvement, but chest radiography continued to show cavities. She was admitted to our hospital because of fever, left pleural effusion and progression of cavities on chest radiographs. She showed no abnormalities of the upper airway or kidney, and was negative for c-antineutrophil cytoplasmic antibody (c-ANCA). Because a positive c-ANCA was seen on day 8 of hospitalization, L-type limited Wegener granulomatosis (WG) was diagnosed according to Gross et al. Prednisolone (PSL) was administered, which improved the anemia, eosinophilia and the cavities. On day 7 of PSL administration, of the left pneumothorax occurred as a complication caused by perforation of the left chest cavity, but her clinical course was good after a cavernectomy was performed. Some studies have reported that limited WG shows a negative c-ANCA, and that antibiotic therapy improves inflammation. The L-type of limited WG revealed a low-grade positive ratio and titer of c-ANCA. Moreover, L-type limited WG responds well to therapy. We therefore selected PSL administration only against L-type limited WG. We have reported L-type limited WG with eosinophilia and the negative effects of c-ANCA at an early clinical stage.

A 35 year-old man was admitted to our hospital because of cough, wheezing, and paresthesia of the right upper extremity. He demonstrated marked eosinophilia, bronchial asthma, and mononeuritis multiplex. We diagnosed Churg-Strauss syndrome. Serum MPO-ANCA was elevated to 189 U/ml. Chest high-resolution computed tomography showed panlobular ground-glass attenuation in both lungs. BALF showed bloody fluid, and TBLB revealed findings consistent with eosinophilic pneumonia. Lung biopsy by VATS revealed eosinophilic pneumonia, pulmonary vasculitis, capillaritis, and hemosiderosis. The patient recovered after treatment with prednisolone and cyclophosphamide. We concluded that alveolar hemorrhage due to pulmonary capillaritis could be a complication in cases of Churg-Strauss syndrome.

Wegener's granulomatosis is a form of systemic vasculitis of unknown etiology that affects the small blood vessels. The disease is characterized by the formation of granulomas on small and medium blood vessels, and often affects the respiratory tract and renal system. In 86% of diagnosed cases, renal compromise is in the form of glomerulonephritis. Wegener's granulomatosis can occur at any age, principally during the 4th and 5th decades of life, and 85% of cases occur over the age of 19 years. In the United States about 3 per 100,000 cases are reported, with a major occurrence in males. The present report is about a case of a 12 year old female with Wegener's granulomatosis of 18 months of evolution, with symptoms such as epistaxis, generalized edema, cough, dyspnea, hemoptysis, high blood pressure and macroscopic hematuria. Out of the five criteria for the diagnosis of Wegener's granulomatosis, she had perinuclear anti-neutrophil cytoplasmic antibody positive to serum p-ANCA mark, which is the least frequent, which makes more difficult the diagnosis. Over a period of five years, in our hospital, we have diagnosed 11 patients with Wegener's granulomatosis, and the present case is the only pediatric case.

A 72-year-old woman had been diagnosed as having organizing pneumonia at another hospital. She was treated with antibiotics, bronchodilators and prednisolone, but her cough, fever and inflammatory signs were not resolved completely. She was admitted to our hospital for further evaluation of the lung lesion. The chest CT scan revealed narrowing of the segmental bronchus and the serum samples showed elevated MPO-ANCA but negative PR 3-ANCA levels. Physical examination also revealed marked bilateral episcleritis and eyeground angitis. Fiberoptic bronchoscopy showed bilateral marked stenotic segmental bronchi associated with mucosal erosions and small nodular lesions. Bronchial and renal biopsy specimens demonstrated marked angitis in the bronchial arteries and glomeruli. A generalized form of Wegener's granulomatosis (WG) was diagnosed and was treated with 60 mg/day of prednisolone, 50 mg/day of cyclophosphamide and 4 g/day of sulfamethoxazole-trimethoprim, which resulted in a marked improvement of the clinical symptoms and endobronchial lesions. In WG, the incidence of endobronchial involvement is 16 to 55% and that of positive serum MPO-ANCA alone is only 14.3%. The present case of WG was considered a rare case with WG which because of the MPO-ANCA-positive but PR 3-ANCA-negative findings associated with marked endobronchial lesions and systemic angitis.

Non-specific interstitial pneumonia developed as an initial manifestation in a patient with microscopic polyangiitis. A 62-year-old man was admitted to our hospital in March 2001, because of fever and intermittent myalgia of lower extremities. Chest X-ray had revealed reticular shadows in the bilateral middle and lower lung fields since 1996. Just before admission, the patient had been diagnosed as having nonspecific interstitial pneumonia (NSIP) from the specimen obtained by video-assisted thoracoscopic surgery (VATS) in another hospital. Physical examination on admission revealed bilateral episcleritis. Laboratory data showed elevated levels of CRP and KL-6, polyclonal gammaglobulinemia, positive rheumatoid factor and myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA). Sensory and motor nerve conducting velocities were delayed in left peroneal nerve, but not other nerves, suggesting mononeuropathy. Biopsied specimens of the left quadriceps revealed vasculitis of arteioles. In spite of positive proteinuria and hematuria, no pathological lesion was found in the kidney. From all of these findings, the patient was diagnosed as having microscopic polyangiitis (MPA) without renal involvement. Methylprednisolone pulse therapy followed by intravenous cyclophosphamide pulse therapy improved his clinical conditions such as pyrexia, cough, myalgia, episcleritis and respiratory symptoms with decreased titer of serum MPO-ANCA. Thereafter, the dose of prednisolone was successfully tapered to 10 mg/day without clinical relapse. In the present patient who developed demonstrated non-specific interstitial pneumonia as an initial manifestation of MPA, VATS provided useful diagnostic and prognostic information, leading to an appropriate therapeutic choice.

A 59-year-old male patient developed a necrotizing ulceration on the right shin. Both clinical and histopathologic examinations suggested pyoderma gangrenosum. After temporary improvement of skin symptoms under peroral glucocorticoid treatment, a hemorrhagic-purulent discharge started from the nose, he began to have fever, malaise, cough, and a chest X-ray revealed inflammation in the lung. Cerebral CT and MRI disclosed midline bone loss within the nasal septum and granulomatosus tissue masses protruding into the right orbit. The c-ANCA test was positive, serum IgA was elevated, and he had microhaematuria and proteinuria. In this severe case of Wegener's granulomatosis prolonged methylprednisone and cyclophosphamide treatment was initiated. Both the skin symptoms and the granulomatosus infiltrations resolved.

A 36-year-old woman presented with a 2-month history of dry cough, bilateral pain in the upper chest, and low-grade fever. She had a 1-year history of ulcerative colitis (UC), which was treated with mesalazine. Cultures of sputum and bronchoalveolar lavage (BAL) fluid were negative. Chest radiograph and a computed tomography (CT) scan showed dense bilateral subpleural infiltrates in both upper lobes. A c-ANCA test was positive in a 1:1280 titer, and further specification showed antibodies against proteinase-3 antigen. Due to the possibility of mesalazine toxicity, this medication was stopped. Within 2 weeks, the patient's symptoms markedly improved, together with the chest roentgenogram.
