A 53 year old man first presented with a mild anti-neutrophil cytoplasmic antibody (ANCA), type (MPO-ANCA) associated microscopic polyangiitis. Approximately one year later, he presented with fatigue, fever, cough, sore muscles and erythrocyturia. At admission he was uraemic. Kidney biopsy showed in LM extracapillary glomerulonephritis and in immunofluorescence microscopy linear deposition of IgG along the glomerular basement membrane (GBM). MPO-ANCA was still positive, but antibodies against GBM were now also present. Retrospective analysis revealed the presence of anti-GBM antibodies nine months before clinical illness. Pr3-ANCA (C-ANCA) was negative during the whole course. In spite of decreasing anti-GBM antibody levels during treatment, his condition aggravated, and he died from complications. Thus, coexisting anti-GBM antibodies may explain suddenly deteriorating renal function in patients with ANCA associated vasculitis.

Blood phagocytes from patients with asthma have an increased capacity to produce reactive oxygen metabolites. We studied whether whole blood luminol-dependent chemiluminescence could detect this phenomenon in patients with a normal spirometry but bronchial hyperreactivity as determined with a methacholine bronchial challenge test. Whole blood chemiluminescence, serum eosinophilic cationic protein (ECP), and serum myeloperoxidase (MPO) were determined from 50 patients referred for a methacholine challenge due to prolonged cough and/or dyspnoea. The chemiluminescence results were compared to those from 15 healthy persons. The hyperreactive patients (n = 18) had significantly higher phorbol 12-myristate 13-acetate (PMA)-induced whole blood chemiluminescence values (mean 18.8 mV.min-1; 95% confidence limits (C.L.) 16.3-21.3 mV.min-1) than the normoreactive patients (mean 14.2 mV.min-1; 95% C.L. 13.0-15.5 mV.min-1;) and the healthy controls (mean 12.8 mV.min-1; 95% C.L. 11.7-13.9 mV.min-1). There was no significant difference in PMA-induced chemiluminescence between the normoreactive patients and the controls. The hyperreactive patients had higher serum ECP values than the normoreactive patients, but there was no correlation between whole blood chemiluminescence and serum ECP levels or total eosinophil count. There was no significant difference in monocyte reactive oxygen metabolite production or serum MPO values between the normoreactive and the hyperreactive patients. We suggest that the increased PMA-induced whole blood chemiluminescence in bronchial hyperreactivity is due mainly to an activation of neutrophils, and that the assay might be useful as a systemic inflammatory marker in patients with pulmonary inflammatory processes resulting in bronchial hyperreactivity.

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.

Here we report an autopsy case with anti-neutrophil antibodies (ANCA) associated vasculitis accompanied by autoimmune hepatitis and hepatocellular carcinoma. A 69-year-old woman was admitted to Tokyo Metropolitan Ohtsuka Hospital in October 1995 because of leg edema. She had presented cough in 1990 and diagnosed as interstitial pneumonia, esophageal varices and liver chirosis. On admission, laboratory data showed mild anemia, hypoproteinemia, and marked gammagloblinemia. IgM-HA antibody, HBs antigen, HBs antibody, HCV antibody and HDV antibody were negative. Anti-nuclear antibody, anticentromere antibody, anti-neutrophil cytoplasmic antibody against myeloperoxidase and cathepsin G (MPO-ANCA and cathepsin G), rheumatoid factor and direct coombs test were positive. Serum level of AFP and CEA were elevated. Ultrasonography and computed tomography of abdomen scowed liver chirosis and tumor in left lobe of liver. The diagnosis of liver chirosis based on autoimmune hepatitis and Interstitial pneumonia was made with clinical course, laboratory findings and radiographic findings although liver biopsy was not performed. She complained of bloody stool due to ulcer of the large intestine, and died of liver failure which progressed rapidly. The autopsy findings detected that pulmonary fibrosis, liver fibrosis with multiple hepatocellular carcinoma, necrotizing crescentic glomerulonephritis, and vasculitis of small artery inn colon. This was the first report of MPO-ANCA associated vasuculitis complicated with autoimmune hepatitis and hepatocellular carcinoma. Clinical significance of ANCA and immunogenetic background of these diseases were discussed.

A 64-year-old Japanese male was admitted to Kotoh General Hospital because of fever and cough on July, 14, 1997. Laboratory data showed hypereosinophilia (11,500/microliter) and high titer of anti-myeloperoxidase antineutrophil cytoplasmic antibody (319 EU). A physical examination revealed progressive peripheral neuropathy. He had been diagnosed as having bronchial asthma since November, 1996. Therefore, he was diagnosed as having Churg-Strauss syndrome (CSS). He was treated with methylprednisolone pulse therapy (500 mg/day for 3 days) and oral prednisolone (PSL, 60 mg/day). However, peripheral neuropathy was rapidly progressive, and echocardiogram revealed cardiac hypofunction (ejection fraction (EF); 39%). He was refereed to Akita University Hospital for further examination. On admission, laboratory data showed hyponatremia (125 mEq/l) with inappropriate secretion of antidiuretic hormone (ADH, 13.0 pg/ml). Atrial natriuretic peptide was normal (26 pg/ml). Urinary osmorality was 488 mOsm/l, and urinary sodium excretion was 86 mEq/l. Renal, adrenal, and thyroid functions were normal. From these data, his hyponatremia was caused by syndrome of inappropriate secretion of ADH (SIADH). After cyclophosphamide-pulse therapy (500 mg) and oral administration of cyclophosphamide (50 mg/day) and PSL (50 mg/day), peripheral neuropathy improved gradually, and his serum sodium returned to normal, but cardiac hypofunction continued. A possible relationship between SIADH and CSS is discussed.

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.

Prolonged cough is a common problem in patients seen in general practice. Using a simple method of sputum induction and processing of sputum samples, we determined whether eosinophilic airway inflammation could be a cause of undiagnosed prolonged cough. Eighty-two patients who had had cough for more than 1 month were enrolled into the study, in six primary healthcare centres. Patients with known pulmonary disease, including asthma or chronic obstructive pulmonary disease (COPD), or who were known to have another cause of cough, or to have recently suffered from a respiratory infection, were excluded. Fifty-three healthy individuals served as controls. Sputum was induced by inhalation of 3% saline. Inflammatory cells in smears were studied semi-quantitatively. Concentrations of eosinophil cationic protein (ECP), eosinophil peroxidase (EPO), myeloperoxidase (MPO) and human neutrophilic lipocalin (HNL) were determined. Sputum induction proved safe and adequate samples were obtained from 91%. Sputum eosinophilia (eosinophils accounting for more than 5% of all cells in smears) was present in 14 patients with prolonged cough (19%) but in no healthy individual (P=0.001). Five of the 14 individuals (36%) who exhibited sputum eosinophilia appeared to have asthma, while nine of the 14 (64%) did not. Concentrations of ECP and EPO were higher in patients with prolonged cough than in healthy individuals (P=0.02 for ECP; 0.005 for EPO). We conclude that eosinophilic airway inflammation is a fairly common cause of prolonged cough, even in patients not suffering from asthma or COPD, or in whom no other cause of cough is known to be present. Induced sputum samples obtained in health centres can be studied in a central laboratory. Detection of eosinophilic airway inflammation could aid the decision regarding treatment.

In childhood asthma, cough is a major symptom in some but not in others. There is only limited data on the frequency, severity and prevalence of cough in children with classical asthma. Studies have largely shown no relationship between cough frequency and cough receptor sensitivity with various asthma severity indices. However relating cough severity with asthma severity is limited by various methodological and sensitivity issues, and these are presented in this paper. Mild asthma exacerbations in a group of children with cough as a dominant symptom were characterised by an increase in cough severity (daytime cough scores) and eosinophilic inflammation but not neutrophilic inflammation. However neither cough receptor sensitivity or cough scores related to airway IL-8, eosinophil cationic protein, myeloperoxidase or serum eosinophil cationic protein, and, asthma scores consistently related to cough score only early in the asthma exacerbation phase.

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.
