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.

The diagnostic criteria for malignant rheumatoid arthritis (MRA), which was proposed by the Research Group of MRA and periarteritis nodosa supported from the Ministry of Health and Welfare has been widely used since 1973. This diagnostic criteria was established for selecting RA patients with life-threatening extraarticular manifestations caused by vasculitis. However, in practice, RA patients with extraarticular involvements related to vasculitis, as well as, cases which were not related to vasculitis were diagnosed as MRA in this criteria. Because of the aforementioned and after research, we revised the diagnostic criteria for MRA. At first, we defined MRA as RA patients having intractable and severe extraarticular manifestations by various causes including vasculitis. One hundred and sixty-nine patients with MRA and 227 patients with RA from 39 medical facilities were analysed. Sixteen extraarticular clinical manifestations and 9 laboratory findings were compared between MRA and RA patients. Comparison of specificity in each criterion for MRA was made by using the Second quantitative analysis. Thereafter, the combinations of the variables which were most specific to MRA were studied. At the same time, sensitivity and specificity for MRA were also studied. The revised criteria are as follows: A. Clinical and Laboratory Findings--(1) visceral infarction, (2) myocarditis, (3) skin ulcer or skin infarction, (4) episcleritis or iritis, (5) polyneuritis, (6) high titers of rheumatoid factor, (7) immune complexes or low complement levels, (8) subcutaneous nodule, (9) pleuritis or pericarditis, (10) interstitial pneumonitis or lung fibrosis. B. Histopathological Findings from Biopsy Specimens--necrotizing vasculitis and/or granulomatous vasculitis and/or endoarteritis obliterans in small and/or medium size arteries.(ABSTRACT TRUNCATED AT 250 WORDS)

A 49-year-old woman was admitted in February 1987, with a six-month history of joint pain, maculopapular and erythematous rash, proximal muscle weakness and a two-month history of skin ulceration and dyspnea on exertion. Physical examination showed Gottron's papules on her fingers and a faint heliotrope rash. Biopsy of erythematous skin lesions on the shoulder and the back of the hand revealed perivascular inflammatory cell infiltration and tiny ulcerative lesions of the cutaneous tissue. Biopsy of the right quadriceps muscle showed type II fiber atrophy and slight perivascular lymphocytic infiltrate, whereas serum CPK level was within normal range. Chest X-ray film showed granular infiltrates in both lower lung fields. Based on the current findings the case was diagnosed as dermatomyositis associated with interstitial pneumonia. The administration of prednisolone, 30 mg/day resulted in the improvement of the skin lesions and muscle weakness, while the intensity of lung infiltrates was little affected. Three months after steroid therapy, the patient was readmitted because of increasing dyspnea on exertion and multiple skin ulcers. Chest X-ray revealed a small amount of gas in the mediastinum, in addition to slight deterioration of interstitial lung disease. In spite of various treatments for pneumomediastinum, including bed rest, administration of analgesics and oxygen inhalation, it developed rapidly, complicated severe subcutaneous emphysema and right-sided pneumothorax. Although high-dose prednisolone therapy and mediastinal drainage were performed, the pneumomediastinum was not resolved and she died from respiratory failure. At autopsy, predominant histological features of the lungs were acute interstitial pneumonia with hyaline membrane and edematous granulation formation in the alveoli.(ABSTRACT TRUNCATED AT 250 WORDS)

The present study was designed to determine the efficacy of filtration leukocytapheresis (LCAP) in the treatment of rheumatoid arthritis (RA) with vasculitis. Nine RA patients with vasculitis were studied by the Malignant RA Collaborative Group formed by 8 clinical centers. A total of 7 filtration LCAP procedures using the Cellsorba column (Asahi Medical Co., Ltd., Tokyo, Japan) were performed with 1 week intervals between treatments. During each apheresis procedure, 3,000 ml of blood was filtered and returned to the patient at a flow rate of 50 ml/min for 60 min. In addition to the amelioration of arthritis, the improvement of extraarticular symptoms associated with rheumatoid vasculitis such as polyneuritis, skin ulcers, digital gangrene and rheumatoid nodules was obtained. In contrast, no improvement was observed in interstitial pneumonia or lung fibrosis. LCAP could be an optional modality for the treatment of RA with vasculitis.

We report two cases of rheumatoid arthritis (RA) who later had developed after polymyositis (PM). The first patient was 64-year old male who experienced muscular weakness of the four limbs in proximity 10 years ago. He was diagnosed as PM because of the elevated serum CK and the myogenic pattern of EMG, and his symptoms were improved by treatment with corticosteroid. He started to complain polyarthralgia 2 years ago, followed by interstitial pneumonia, pleuritis and skin ulcer. He was admitted because of exacerbated polyarthralgia, multiple subcutaneous nodules, skin eruption and fever. The level of serum CK was within normal range but CRP was elevated and CH 50 was decreased. The laboratory examination showed positive cryoglobulin and high titer of rheumatoid factor, but anti-Jo 1 antibody was negative. The hand X-ray showed bone erosions in bilateral wrist joints. Skin biopsy revealed leukocytoclastic vasculitis. Based on these findings, he was diagnosed as malignant RA. He was successfully treated with methylprednisolone pulse therapy, cyclophosphamide and prostaglandin E 1. The second patient was 77-year old male with pneumoconiosis who experienced muscular weakness of the four limbs in proximity 4 years ago. He was diagnosed as PM based on his clinical and laboratory findings and was treated with temporary corticosteroid. He started to have polyarthralgia last year, and he was admitted because of increasing arthralgia after the treatment of pulmonary tuberculosis. The level of serum CK was slightly elevated due to hypothyroidism, and CRP was highly elevated. Rheumatoid factor and cryoglobulin were positive, but anti-Jo 1 antibody was negative. The hand X-ray showed bone erosions in bilateral wrist joints. Crystals of pyrophosphate calcium was observed in knee joints. He was diagnosed as RA associate with pseudogout. His symptoms were relieved with corticosteroid, salazosulfapyridine and anti-tuberculous therapy. These two cases had altered their clinical features from PM to definite RA, and both had pulmonary complications. Previous reports described the cases of RA followed by PM, most of which were induced by such drugs as D-penicillamine, but the cases of PM who later had developed RA are extremely unusual. The overlapped cases of RA and PM tend to highly associate with pulmonary lesions.

We herein describe a case of refractory dermatomyositis (DM) complicated with myelodysplastic syndrome (MDS). Despite intensive immunosuppressive therapies, the activity of myositis, skin ulcers, and interstitial pneumonia did not improve. The patient ultimately died following the progression of interstitial pneumonia. There are few reports of DM accompanying MDS to date, and any association in the pathogenesis between the two is still unclear. However, underlying MDS may have the potential to influence the therapeutic response of DM.

Chylothorax is a disease in which chyle leaks and accumulates in the thoracic cavity. Interstitial pneumonia and pneumomediastinum are common thoracic manifestations of dermatomyositis, but chylothorax complicated with dermatomyositis is not reported. We report a case of dermatomyositis with interstitial pneumonia complicated by chylothorax. A 77-year-old woman was diagnosed as dermatomyositis with Gottron's papules, skin ulcers, anti-MDA5 antibody and rapid progressive interstitial pneumonia. Treatment with betamethasone, tacrolimus and intravenous high-dose cyclophosphamide was initiated, and her skin symptoms and interstitial pneumonia improved once. However, right-sided chylothorax began to accumulate and gradually increase, and at the same time, her interstitial pneumonia began to exacerbate, and skin ulcers began to reappear on her fingers and auricles. Although her chylothorax improved by fasting and parenteral nutrition, she died due to further exacerbations of dermatomyositis and interstitial pneumonia in spite of steroid pulse therapy, increase in the betamethasone dosage, additional intravenous high-dose cyclophosphamide and plasma pheresis. An autopsy showed no lesions such as malignant tumors in the thoracic cavity. This is the first report of chylothorax complicated by dermatomyositis with interstitial pneumonia.
