A patient with diffuse eosinophilic gastroenteritis, associated with progressive chronic interstitial pulmonary fibrosis, was followed for 29 years. His major symptoms were recurrent gastrointestinal bleeding, anemia, diarrhea, malabsorption, and increasing respiratory insufficiency. Multiple jejunal biopsies revealed eosinophilic infiltration and extensive villous atrophy. Results of a lung biopsy and pulmonary function tests were consistent with chronic interstitial pulmonary fibrosis. His gastrointestinal symptoms responded to steroid therapy, but he died of progressive respiratory insufficiency. At autopsy, villous atrophy was noted to extend throughout the whole extent of the small intestine in association with multiple "pseudopolypoidal" inflammatory lesions.

Central nervous system is rarely involved in progressive systemic sclerosis (PSS) unless there are concomitant abnormalities in renal or lung function or hypertension. A 72-year-old woman with typical PSS developed cerebellar bleeding. Medical history records revealed, she had noted the onset of Raynaud's sign on her upper extremities at the age of 37. This was followed by necrosis and repeated infection, and as a result, shortening of her fingers in her 40's. The disease progressed and involved lower extremities, and then face and body in her 50's. Aortic valve stenosis was diagnosed at 69 year old, cardiac myopathy at 70 and at the age of 71 infectious dermatitis in both inguinal regions. Mild anemia, hypoalbuminemia and the decrease of serum Fe were discovered in June 1988. At the same time, prolonged ESR, positive C-reactive protein, RA, and anti-nuclear-antibody were also noticed. A chest roentgenogram revealed pulmonary fibrosis. Systemic hypertension was not noticed on the clinical course. She developed an onset of vertigo and vomiting in the morning of August 8, 1988. Consequently, she was brought to our hospital. She was alert but a physical examination showed a swallowing disturbance, dysarthria, right cerebellar ataxia, nystagmus and hypertension (192/100 mmHg). A CT examination on admission revealed a slightly low density area in right cerebellar hemisphere without mass effect. She was treated with dextran and mannitol and her condition improved on the 6th day of her admission. She was alert and blood pressure calm down to 120/70 mmHg without the use of anti-hypertension drugs on August 21.(ABSTRACT TRUNCATED AT 250 WORDS)

Eight patients with myelodysplastic syndromes (MDS) were treated with bone marrow transplantation (BMT). Median age was 34.5 years and ranged between 3 and 45. FAB diagnosis was refractory anaemia (RA) in three, RA with excess of blasts (RAEB) in four and RAEB in transformation (RAEB-t) in one case. Four patients were prepared with cyclophosphamide and total body irradiation whilst the other four received busulphan and cyclophosphamide. Engraftment was documented in seven of eight patients. Two patients died from complications related to the procedure. One had early veno-occlusive disease of the liver whilst the other died 46 months after BMT from pulmonary fibrosis. One patient died from recurrent disease 11 months after BMT. Five patients are alive and in complete remission 9-35 months post-transplantation. Four of these patients have a Karnofsky score greater than or equal to 90%. These results suggest that BMT can induce prolonged disease-free survival in patients under 50 years of age. If a compatible donor is available, marrow transplantation should be seriously considered in the treatment of MDS.

From 1960 to 1984, 78 new patients with progressive systemic sclerosis were followed up: 60 women and 18 men whose ages ranged from 20 to 83 years, with a mean age of 58 years. Twenty nine are known to be dead and 3 were lost of follow-up. Forty six have been followed up to the present time for a mean period of 5 years. The cumulative survival rates were 88 +/- 7 p. 100 at one year, 62,5 +/- 11,5 p. 100 at five years and 50,5 +/- 15 p. 100 at ten years. These figures are significantly different from those found in a matched group from the French general population. Nine features at the time of diagnosis which might influence prognosis were studied. Seven factors apparently have not affected prognosis: sex, age, time elapsed between initial symptom and definitive diagnosis, location of scleroderma, blood pressure, erythrocyte sedimentation rate and creatinine clearance. On the other hand, survival declined significantly faster in the 28 patients with anemia than in the 50 patients without anemia (P less than 0,001). Similarly, the 47 patients with radiological pulmonary involvement or pulmonary function abnormalities were at significantly higher risk for death than the 31 patients without interstitial pulmonary fibrosis. Anemia and pulmonary involvement are predictors of mortality and important prognostic tools in the management of the different drugs that have been recommended for the treatment of patients with systemic sclerosis.

The influence of the hemoglobin concentration in the peripheral venous blood on the diffusing capacity of the lungs for CO (DLCO) was tested with the single-breath method. 9 patients with histologically verified interstitial pulmonary fibrosis of varying etiology and 26 persons with healthy lungs with anemia requiring transfusions were investigated before and after compensation of the anemia. It was found that the true maximum diffusing capacity of the lungs measured in anemia patients was too low. In the test subjects with healthy lungs, there was a positive linear correlation between the hemoglobin content of the blood and DLCO. A correction factor to calculate the true DLCO in patients with healthy lungs but with anemia is specified. In the patients with interstitial pulmonary fibrosis, the influence of the reduced diffusing capacity of the alveolocapillary membrane on the extent of the diffusion disorder was in each case greater than the effects due to the anemia.

Idiopathic pulmonary haemosiderosis (IPH) is a rare disease characterized by recurrent episodes of intrapulmonary bleeding, chronic iron deficiency anaemia and pulmonary fibrosis. IPH is a diagnosis made by exclusion of other causes. It occurs in both adults and children. Other conditions than IPH can cause pulmonary haemosiderosis. The etiology is unknown, but might be an immunological mechanism causing a defect in the basement membrane of the pulmonary capillary. IPH should be suspected in patients with recurrent episodes of coughing, haemoptysis, dyspnoea and anaemia. Chest X-ray shows pulmonary infiltrates during an acute attack. Examination of sputum or lung biopsy discloses large numbers of haemosiderin-laden pulmonary macrophages. The mortality-rate is high, but the prognosis is difficult to evaluate because many patients survive for a long time either with a course of recurrent attacks or with chronic symptoms, such as dyspnoea and persistent anaemia. Steroids may improve the condition of the patient during a bleeding episode.

Progressive tissue iron deposition from multiple blood transfusions is common in beta-thalassaemia and pulmonary iron deposition may result in parenchymal damage. The objectives of this study were to: 1) determine the predominant pulmonary dysfunction in patients with thalassaemia major; and 2) demonstrate that parenchymal disease, if present, is at the level of the alveolocapillary membrane. Fourteen thalassaemia major patients (13 nonsmokers) receiving regular blood transfusion and without any history of chronic respiratory disease were recruited. Pulmonary function tests and echocardiography were performed before the scheduled transfusions. Three patients with the most restricted lung function were selected for high resolution computerized tomography (CT) of the lungs. One patient had an obstructive pattern with a forced expiratory volume in one second as percentage of forced vital capacity (FEV1/FVC) of 71%. Four patients demonstrated a restrictive pattern, as defined by total lung capacity (TLC) less than 80% predicted with normal FEV1/FVC%. Twelve patients had pulmonary transfer factors for carbon monoxide (TL,CO) below 80% pred, even after correction for the anaemia, indicating parenchymal disease. Eight of these 12 patients had alveolocapillary membrane defect, as demonstrated by a gas transfer factor of the pulmonary membrane (Tm) less than 80% pred. Mean resting arterial oxygen saturation was 95 +/- 2 (range 92-98) %. Eleven patients had oxygen desaturation of 5% or more during exercise on a bicycle ergometer, consistent with interstitial lung disease. There was no clinical or echocardiographic evidence of heart failure. Percentage predicted TLC was inversely correlated with age (r = -0.547; p = 0.043). Both percentage predicted TLC and TL,CO were not correlated with iron burden or desferoxamine ratio. High resolution CT in the three selected patients showed no evidence of pulmonary fibrosis. We conclude that thalassaemia major patients have a predominant restrictive lung dysfunction with pulmonary parenchymal disease and alveolocapillary membrane block. The restrictive and interstitial lung disease could not be accounted for by iron loading or pulmonary fibrosis in our patients.

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 51-year-old woman was admitted to a local hospital because of pneumonia, and received a diagnosis of cervical lymphadenopathy, anemia, and hyperimmunoglobulinemia with suspected multicentric Castleman's disease (MCD). At the age of 53 she was transferred to our hospital because of numbness and muscle weakness. Polyclonal hyperimmunoglobulinemia was observed, and biopsy specimens of lymph node tissue revealed infiltration of plasma cells in the interfollicular areas, thus leading to a diagnosis of MCD. A chest computed tomography scan revealed diffuse nodular shadows in all lung fields, and a transbronchial lung biopsy disclosed infiltration of plasma cells in the alveolar septa. Together, these findings indicated lymphoid interstitial pneumonia (LIP). Polyneuropathy was diagnosed by neurological examination and nerve conduction studies. Treatment with prednisolone and cyclophosphamide was ineffective against LIP probably because the patient had coexising pulmonary fibrosis. Since pulmonary complications of MCD determine its prognosis, their early detection and treatment are essential.

Dyskeratosis congenita (DC) is a rare inherited disorder often associated with aplastic anaemia. We report the cases of five boys transplanted with an HLA-identical related donor for severe aplastic anaemia (SAA) associated to DC; in all cases successful engraftment was observed. Three patients died 2-8 years after bone marrow transplantation (BMT) with signs of endothelial cell damage syndrome (kidney microangiopathy and liver veno-occlusive disease). Another boy died 1 year after BMT from Evans syndrome and invasive aspergillosis. One boy currently presents anaemia, polyarthritis of unknown origin, pulmonary fibrosis and gut malabsorption 7.5 years after BMT. SAA associated with DC can be successfully treated by allogeneic BMT. However, these early and late complications observed are very unusual after BMT and probably reflect the association of transplanted-related factors, evolution of the underlying disease, and increased sensitivity of endothelial cells. Modified conditioning approaches, advances in supportive care and surveillance of these unusual complications offer the possibility of improved outcome for these patients.
