Treatment of disseminated intravascular coagulation and its prodromal stage with gabaxate mesilate (FOY): a multi-center trial.

One hundred and ninety-one patients with disseminated intravascular coagulation syndrome (DIC) or its prodromal stage (preDIC) were treated with only gabaxate mesilate (FOY) (group G) or a combination of gabaxate and unfractionated heparin (group GH), and the efficacy of gabaxate was evaluated in a multicenter study. Following the treatment, the mean DIC score, which was evaluated on the basis of clinical symptoms and hemostatic parameters, decreased significantly to 5.58 +/- 3.48 from 6.75 +/- 3.14 in group G (p < 0.001) and to 6.34 +/- 3.33 from 7.31 +/- 3.00 in group GH (p < 0.05). In patients with overt DIC, the mean score decreased to 6.71 +/- 3.54 from 8.42 +/- 2.84 (p < 0.001). In DIC, the rate of overall efficacy was 46.2% in group G and 35.1% in group GH. In preDIC, it was 41.5% in group G and 27.3% in group GH. No side effects, including severe bleeding, were found in this study. The results indicate that gabaxate mesilate is clinically effective for patients with DIC and preDIC.

[Thrombotic thrombocytopenic purpura (TTP) in which plasmapheresis was ineffective but vincristine slow infusion therapy was effective with long-term remission].

A 38-year old female patient with thrombotic thrombocytopenic purpura (TTP) did not respond to plasmapheresis and treatment with corticosteroids and antiplatelet agents but did respond to subsequent high-dose gamma-globulin therapy and vincristine slow infusion therapy. Remission, thought to be due to vincristine, was achieved. The administration schedule of vincristine was 1 or 2 mg once a week by intravenous drip infusion over a period of 6 to 8 hr. Improvement tended to be seen after the 6th administration, and remission was achieved after the 12th administration (total dose: 15 mg), and continues to the time of this writing. In this case, it was thought that vincristine inhibited a certain excessive reaction in the process of PAIgG-related platelet consumption. We conclude that vincristine should be administered at least 5 to 6 times, and the therapeutic method should be established based on the experience in a larger number of clinical cases.

[Neutrophil chemiluminescence in pneumoconiosis].

Neutrophilic phagocytic activity and serum opsonic activity were examined in pneumoconiosis patients. One hundred patients aged 43 to 81 were classified into four types (types 1 to 4) according to the degree of chest X-ray findings. A simultaneous multiple measurement system for luminol-dependent chemiluminescence was used. Neutrophilic phagocytic activity and serum opsonic activity were shown by the time length to reach peak chemiluminescence (PT) and the height of peak chemiluminescence (PH). There were no significant differences of neutrophilic phagocytic activities and serum opsonic activities between normal persons and type 1 cases of mild disease. However, these activities were elevated in cases with more severe disease, and the most severe type 4 type cases tended to show lower activities than type 2 and type 3 cases. PT of total chemiluminescence was influenced by both neutrophilic phagocytic activity and serum opsonic activity, but PH only by neutrophilic phagocytic activity. Statistically significant correlation was observed between serum opsonic activity and serum CH50 levels.

Lung cancer complicated by silicosis: a clinical and histopathological study.

A clinicopathological analysis was carried out on 16 cases of lung cancer complicated by silicosis, which were diagnosed from April 1975 to March 1983, and the results were discussed with a review of the literature. All of the patients were male, and a smoking habit with a Brinkman index of more than 500 was found in 14 of them (87.5%). Twelve cases (75.0%) had advanced tumors of clinical stages III and IV, suggesting that the early detection of lung cancer complicated by silicosis is difficult. Tumors were uniformly found in all lobes of the lung. Histological types were mainly epidermoid or undifferentiated carcinoma, with very few adenocarcinomas. Carcinogens from smoking seemed to be responsible for the carcinogenesis. Two cases were thought to be scar carcinomas.
