[Course of interstitial lung diseases associated with inflammatory myopathies. Apropos of 5 cases].

We describe five cases of polymyositis/dermatomyositis with interstitial lung disease, occurring in women, with a mean follow up of 28 months (15 to 51). One remained without respiratory symptoms, two had a chronic and relapsing course, and two an acute course, leading to death with respiratory failure in one. Anti-Jo1 antibody was found in two patients, without relation to the gravity of the respiratory illness. The two others with a severe course had anticardiolip antibodies, and one cutaneous necrosis of the fingers. Cancer-associated dermatopolymyositis was never seen at diagnosis, but a lymphoma of the brain was diagnosed after two years in one patient. Combination of corticosteroids with another immunomodulator treatment was necessary for all, because of frequent relapses. Methotrexate was effective in one case for the muscular and the respiratory signs, plasma exchanges with azathioprine in two cases, and intravenous immunoglobulin in one patient with acute lung injury.

[Microscopic polyarteritis].

Microscopic polyarteritis is an idiopathic necrotising vascularitis of the small vessels. Manifestations include diffuse alveolar haemorrhage, segmentary necrotising glomerulonephritis, and a cutaneous, articular, neurological or digestive vascularitis. The absence of a histological granulomas and medium calibre vessel involvement distinguishes Wegener's syndrome from polyarteritis nodulosa. The diagnosis is facilitated when anti-neutrophil cytoplasm antibodies are found in the serum. These auto-antibodies are suspected to be the cause based on clinical and experimental data, although this aetiology has not been confirmed. Corticosteroids, immunosuppressors and plasmapheresis can improve the prognosis of this severe and evolving affection which may be fatal.

Prothrombin fragment 1 + 2, thrombin-antithrombin III complexes and D-dimers in acute deep vein thrombosis: effects of heparin treatment.

Plasma levels of prothrombin fragment 1 + 2 (F 1 + 2), of thrombin-antithrombin III complexes (TAT) and of D-dimers were evaluated at several time intervals in 15 patients affected by acute proximal deep vein thrombosis, complicated or not by pulmonary embolism, and treated by conventional heparin therapy for 9 d. The mean levels of the three markers remained significantly increased throughout the period of observation, except for F 1 + 2 on day 9, when compared to normal values established in a population of normal healthy blood donors. However, whereas heparin significantly decreased the plasma levels of F 1 + 2 and of TAT complexes in less than 3 d. D-dimer levels were not significantly altered. Significant correlations were observed between the plasma levels of the three markers but they were not correlated to the actual intensity of heparin treatment evaluated as the activated partial thromboplastin time prolongation. These results indicate that heparin improves the hypercoagulable state associated with a deep vein thrombosis within the first days of treatment as indicated by TAT and F 1 + 2. They also account for the performances of D-dimer assay for the diagnosis of deep vein thrombosis in patients already receiving heparin, a common situation in routine hospital practice.
