Interstitial pneumonia is well known as one of the complications of rheumatoid arthritis (RA). While interleukin-2 (IL-2) regulates the immune response through IL-2 receptor (IL-2R), the exact role of the soluble form of IL-2R (sIL-2R), recognized as a part of the alpha chain or IL-2R, is still obscure. So, the immunological significance of sIL-2R in serum and in bronchoalveolar lavage fluid (BALF) of those of RA patients with or without interstitial pneumonia was studied. The sIL-2R was measured with an ELISA kit (T-Cell Science Ltd). The levels of sIL-2R in the sera of RA patients without interstitial pneumonia were significantly higher than those of normal controls. Furthermore, the levels of sIL-2R showed a statistically significant correlation with ESR and Lansbary's index. The levels of sIL-2R of RA patients with interstitial pneumonia were higher than in those without interstitial pneumonia although the evaluation of class and stage of arthritis in those RA patients with or without interstitial pneumonia revealed no significant difference. A high sIL-2R/albumin ratio in BALF of RA patients with interstitial pneumonia was shown in comparison with those of normal control. These data indicate that the estimation of sIL-2R in RA patients could be useful in estimating the disease activity and that high levels of sIL-2R reflect the active immune response in the lungs of RA patients with interstitial pneumonia.

The authors recently experienced a case of idiopathic interstitial pneumonia (IIP) that exhibited skin ulcers due to increased heparin precipitable fraction (HPF) in plasma. This case prompted us to investigate the occurrence and significance of HPF in interstitial pneumonia (IP). The subjects included patients with IIP (acute exacerbation 6 cases, chronic active stage 12 cases), IP associated with collagen vascular disease (CVD) (9 cases) and granulomatous lung diseases (7 cases). The data indicated that all of the cases with acute exacerbation of IIP exhibited increased plasma HPF values (218-951 mg/dl) compared to those of normal controls (less than 180 mg/dl). In contrast, the values ranged within normal limits in all of the cases with IP associated with CVD. In a companion study, we measured plasma HPF values in patients with lung cancer, bacterial pneumonia and diffuse panbronchiolitis. It was found that 22% of the subjects showed increased plasma HPF values. We also investigated whether there were correlations between plasma HPF and various inflammatory parameters. The data revealed that there were correlations between HPF and ESR, CRP, alpha 1-globulin, alpha 2-globulin, complement (C3) or fibrinogen. However, there was no correlation between HPF and fibronection. These results suggest that plasma HPF is valuable to evaluate the acute exacerbation of IIP, although the elevation of plasma HPF levels is not specific.

Although substantial patients are dead in the course of PM/DM, little papers have precisely investigated the cause of death and factors which may relate to death in PM/DM. The purpose of the present study is to evaluate the prognosis for life, causes of death and risk factors for life in PM/DM. Clinical records of 76 adult PM/DM patients were retrospectively reviewed. Seven patients died of associated malignancy. Five-year survival rate was 69.7% in PM/DM patients without malignancy. During the last 24 years, there was no significant change in survival rate. Among causes of death in 19 cases without malignancy, 7 cases died of respiratory failure and 7 patients died of cardiac involvement. There seems to be two types of pulmonary involvement causing respiratory failure; i.e. acute interstitial pneumonitis and chronic interstitial pneumonitis. In the former cases, the courses were very rapid, and patients died during 4 months after appearance of the first symptom. Risk factors were chosen by comparing clinical manifestation in dead patients with those in control subject. Control subjects were selected from non-dead patients by matching with sex, age, and duration after start of the first therapy. Acute onset disease, fever, arthritis, hypergammaglobulinemia, elevated ESR (greater than or equal to 30 mm/hr), lung fibrosis, and heart involvement are risk factors for life.

The clinical, radiological, physiological and pathological features were studied in 6 cases of idiopathic bronchiolitis obliterans organized pneumonia (BOOP). Patients characteristically had a history of exertional dyspnea, cough, fever, weight loss, bilateral radiographic shadowing, elevated ESR and hypoxemia. Corticosteroids were effective; however, one patient died of cytomegalovirus pneumonia. The pathological features, distinguished by the presence of granulation tissue plugs extending from bronchioles into alveolar ducts and alveoli, are described in detail. The place of BOOP within the broad spectrum of bronchiolitis obliterans between small airways disease and usual interstitial pneumonia is discussed.

A forty-eight year-old female with rheumatoid arthritis developed cough, sputum and dyspnea. Chest X-ray film demonstrated bilateral diffuse interstitial pneumonia and pulmonary fibrosis. Laboratory findings were as follows: ESR 29 mm/h, CRP 3.86 mg/dl, RA test (+), RAHA (-) and WBC 7200/mm3. Marked hypoxemia (po(2)45 Torr) was demonstrated by blood gas analysis. Asymptomatic pulmonary fibrotic lesions which preceded articular symptoms were identified on her previous chest X-ray films. Methylprednisolone-pulse therapy (1g/day, for 3 days) was repeated three times with a 2-week interval. The treatment rapidly improved both pulmonary symptoms and chest X-ray findings. Although the fibrotic shadows on chest X-ray did not completely disappear, her conditions have been maintained well under the treatment with prednisolone (10mg/day) plus D-penicillamine (200mg/day).

The incidence and latency period of collagen vascular disease (CVD) were surveyed prospectively in patients originally diagnosed as idiopathic interstitial pneumonia (IIP). We also examined whether there were differences between IIP and CVD preceded by interstitial pneumonia. Background information, extrapulmonary symptoms, smoking history, laboratory findings, prognosis (Kaplan-Meier estimates), respiratory functions, and radiological findings were compared. The subjects consisted of 68 patients of whom 13 (19%) developed CVD (RA; 5 cases, DMPM; 5 cases, SLE; 1 case, Sjoegren syndrome; 1 case, Overlap syndrome; 1 case). The latency period for development of CVD was 24.9 +/- 39.2 (mean +/- SD) months. IIP patients who developed CVD were predominantly female and were younger than those without CVD (p less than 0.05). These patients also had faster ESR, higher CPK values, and a higher incidence of arthralgia, joint deformity and clubbed fingers (p less than 0.05). Abnormal shadows around costo-phrenic angles were seen more frequently in patients with CVD (p less than 0.05). These results suggest that quite a number of patients with IIP develop CVD. The clinical course of these patients should be followed by keeping these clinical findings in mind.

Forty-four patients with definite or classical rheumatoid arthritis were entered in a 48-week open study, comparing the long-term effects of Timegadine and D-penicillamine. Twenty-three and 21 patients were respectively allocated to the Timegadine and D-penicillamine groups. Two patients of the former group were lost for follow-up, soon after the first baseline. Thus data were available only for 42 patients, 21 in each group of whom eleven completed the 48-week period in each group. Seven patients in the Timegadine group stopped because of ineffectiveness, 2 because of skin eruption and 1 because of acute interstitial pneumonitis. In the D-penicillamine group, 9 patients dropped out: 3 because of proteinuria, 2 because of stomatitis, 1 because of dizziness and 1 because of headache. Pain (visual analogue scale), number of swollen and painful joints improved significantly in both groups (p less than 0.05). The acute phase reactants alpha1-acid-glycoprotein and ESR and the thrombocyte count significantly decreased in the penicillamine group (p less than 0.05). The other clinical, hematological and immunological tests did not change; neither did the liver and kidney function tests. The clinical results suggest that Timegadine is as effective as D-penicillamine in the treatment of rheumatoid arthritis. D-penicillamine takes advantage over Timegadine by decreasing significantly the acute phase reactants. However, Timegadine has a low profile of side-effects.

The paper reports a rare case of 26-year-old female with diffuse infiltrative lesions in both lungs. Blood tests revealed hypergammaglobulinemia and fast ESR. Lung biopsies exhibited diffuse lymphoid infiltration with fibroatelectasis regions. Cytological and immunophenotypic studies of the lavage showed polyclonal composition of the cell population and prevalence of mature lymphocytes. The diagnosis was made of lymphocytic interstitial pneumonia (LIP). No progression of the condition was observed. In view of expected malignant transformation the case was followed up. Benign characteristics of lymphocytic infiltration, no negative shifts within 5 years allow avoiding active immunodepressive treatment in this stage of the disease which belongs to diffuse forms of pseudolymphoma and is considered to be a prelymphomatosis status.

We studied two cases of the elderly with acute exacerbation of interstitial pneumonia to elucidate a prognostic role of super oxide generation in peripheral whole blood. The first case was a 70-year-old man, who presented with acute exacerbation of interstitial pneumonia and was hospitalized. Following steroid-pulse therapy, CRP, ESR, blood-gas and his physical condition improved, resulting in successful discharge. In this case, super oxide generation standardized by the number of neutrophils (K) decreased to less than 1.0 in association with the improvement of physical condition. The second case was a 92-year-old woman in whom acute exacerbation of interstitial pneumonia was diagnosed. While the pulse therapy, CRP, LDH and blood-gas temporarily improved, K was continuously greater than 1.0 and the physical condition worsened, resulting in her death. These cases suggest that the measurement of super oxide generation in peripheral whole blood may play a useful role in assessing the prognosis of the elderly with acute exacerbation of interstitial pneumonia.

The serum concentration of several markers in patients with collagen disease was studied to evaluate the useful indices for the diagnosis of interstitial pneumonia/pulmonary fibroses (pneumonitis). Procollagen N-terminal type III peptides, type IV collagen and monoamine oxidase were measured as the fibrosing markers. Squamous cell related antigen (SCC) and soluble cytokeratin 19 fragments (CYFRA21-1) were measured as the tumor markers. Hyaluronic acid, ESR and CRP were measured as the inflammation markers. The 119 patients with collagen disease (71 patients with RA, 16 with SSc, 9 with SLE, 8 with PM/DM, 6 with MCTI) and 9 with other collagen diseases) who have been followed in our hospital were studied. Of 119 patients, 23 patients (RA14, SSc7, PM/DM2) were complicated with pneumonitis. The results were as follows. 1. All the serum markers except CYFRA21-1 had no significantly difference between with and without pneumonitis. The serum CYFRA21-1 level in the pneumonitis group was higher than that of the non pneumonitis group (1.38 vs 0.66 ng/ml, P < 0.001). 2. The cut-off value was set at 2.0 ng/ml, corresponding to 26.1% sensitivity and 97.9% specificity for pneumonitis complicated with collagen disease. 3. The CYFRA21-1 level in early stage of pneumonitis group (from onset to measurement < 1 year) was significantly higher than that of late stage group (from onset to measurement > 1 year). And there are 75.0% sensitivity in early stage of pneumonitis group. 4. Case study was suggested that CYFRA21-1 had a potential as a diagnostic and monitoring marker for pneumonitis.
