A specific, sensitive, and reproducible radioimmunoassay for human plasma thromboplastin antecedent (PTA, factor XI) has been developed with purified PTA and monospecific rabbit antiserum. Precise measurements of PTA antigen were possible for concentrations as low as 0.3% of that in normal pooled plasma. Normal plasma contained approximately 6 microgram PTA/ml. A good correlation (correlation coefficient 0.68) existed between the PTA procoagulant assays and radioimmunoassays among 50 normal adults (25 males and 25 females). PTA antigen was markedly reduced in plasma of 13 patients with congenital homozygous PTA deficiency (range less than 0.003-0.128 U/ml) and 9 patients with hepatic cirrhosis (0.35+/-0.17 U/ml), but was normal in those of 9 patients under treatment with warfarin, 8 patients with disseminated intravascular coagulation and 16 patients with other congenital clotting factor abnormalities, including prekallikrein deficiency (Fletcher trait) and high molecular weight kininogen deficiency (Fitzgerald trait).

Coagulation studies were performed on 13 children with clinical diagnoses of Reye syndrome. Four had abnormalities so severe that transfusion of coagulation factors and platelets were required prior to percutaneous liver biopsy. In one of these, abnormalities frequently found in association with acute hepatic failure were present. Disseminated intravascular coagulation was noted in two, while in the fourth child laboratory data were most consistent with that process. Although the coagulation defect associated with Reye syndrome is most often due to decreased production of all coagulation factors except VIII, these patients demonstrate that consumption can also occur. The severity of the coagulopathies found indicates that bleeding can become a major complication in the diagnosis and management of Reye syndrome.

Six cases of coronary embolism and myocardial infarction associated with nonbacterial thrombotic endocarditis were seen at the Mount Sinai Hospital over a ten-year period. Every patient had an underlying malignant neoplasm. The vegetations were found on aortic, mitral, tricuspid and pulmonic valves and were located on the free or closure margins. The clinical diagnosis of this condition is difficult because of simultaneous embolization to the brain, causing widespread neurologic symptoms, but could be made by electrocardiographic and serum enzyme studies. Myocardial infarction caused the deaths of three patients. The relationship between nonbacterial thrombotic endocarditis, hypercoagulability, and disseminated intravascular coagulation is discussed.

Our previous studies suggested that disseminated intravascular coagulation (DIC) may be a sequel to saline-induced abortion. A hypothetical mechanism for the DIC is that hypertonic saline produces cellular disruption in the products of conception with the release of thromboplastic substances into the amniotic fluid. These substances, in turn, diffuse through the damaged membranes into the maternal circulation. To examine this hypothesis we obtained samples of amniotic fluid (AF) from 5 patients just prior to and at 1 hour, 6 hours, and 24 hours after intraamniotic instillation of hypertonic saline. The procoagulant and thromboplastic properties of the various AF specimens were quantitated using the prothrombin time (PT), partial thromboplastin time (PTT), and activated clotting time (ACT) as in vitro test systems. The results indicate that a change in the procoagulant and/or thromboplastic activity of AF following saline instillation is not afactor in the pathophysiology of DIC associated with saline abortion.

A secific, sensitive, and reproducible radioimmunoassay for human Hageman factor (HF, factory XII) has been developed with purified human HF and monospecific rabbit antibody. Precise measurements of HF antigen were possible for concentrations as low as 0.1% of that in normal pooled plasma. A good correlation (correlation co-efficient = 0.82) existed between the titers of HF measured by clot-promoting assays and radioimmunoassays among 42 normal adults. Confirming earlier studies, HF antigen was absent in Hageman trait plasma, but other congenital deficient plasmas, including those of individuals with Fletcher trait and Fitzgerald trait, contained normal amounts of HF antigen. HF antigen was reduced in the plasmas of patients with disseminated intravascular coagulation or advanced liver cirrhosis, but it was normal in those of patients with chronic renal failure or patients under treatment with warfarin. HF antigen was detected by this assay in plasmas of primates, but not detectable in plasmas of 11 nonprimate mammalian and one avian species.

A 42-year-old male patient became hospitalized with severe back pain and marked bleeding tendency from disseminated intravascular coagulation. The bone marrow aspirate showed numerous nests of cancer cells presumably from a prostatic carcinoma. After only 4 days of treatment with diethylstilbestrol his condition was markedly improved, and a new bone marrow aspirate showed extensive necrosis of the cancer cells.

The fibrin-fibrinogen degradation products (FDP) tests were studied in 18 patients having a history of illness associated with diving. FDP tests were performed prior to hyperbaric oxygen therapy (OHP). Eight patients were serious neurologic signs had positive FDP tests and required repetitive therapy. Six patients had negative FDP tests with local musculoskeletal complaints and all were asymptomatic following the first OHP treatment. Three patients were found to be suffering from other diseases. These three patients had normal levels of FDP. One patient treated at another facility 3 months earlier and having paraplegia had a positive FDP test. Serious decompression sickness with neurologic complaints appear to have some degree of disseminated intravascular coagulation (DIC) as reflected by the FDP tests. The FDP test appears to be a useful screening test that may be able to delineate therapy.

We analyzed the gestational, parturitional, neonatal (GPN) histories of 281 severely mentally retarded patients with cerebral palsy to define the etiology or pathogenesis of cerebral palsy in each patient. No association between type of cerebral palsy and GPN histories was found except for an increase in spastic-athetoid patients in the breech delivery subgroup. Significant findings include: increased incidence of prematurity and postmaturity, small and large for-gestational age (GA) fetal size, a normal birthweight for GA distribution of patients with diabetic mothers, an excess of mothers greater than or equal to 35 and less than or equal to 20 years old, an increased immediately-previous sib interval of 2.59 years suggestive of an "infertility factor", an unremarkable GPN history in one third of the cases, in another one third GPN problems not usually associated with a high risk of CNS damage, and in one third gross complications which were probably responsible for the CP, including: an increased incidence of breech deliveries, twinning, prolonged and precipitous labor and placental complications; no increased association of athetosis and Rh incompatibility or incidence of toxemia was found. Disseminated intravascular coagulation due to prenatal death of a twin may have been the cause of brain damage in several patients.

Haemostasis in the new-born is a product of various factors which are both qualitative and quantitative. The only factors that compare in levels and quality with those in the adult are factors V, VIII and XIII. They are alterations in the semi-analytical tests for coagulation except in the Stypven time. In contrast with this deficit shown up in haemostasis by global tests coagulation is normal and in truth there is hypercoagulability. Using Laurell's method of immunoelectrophoresis for levels of alpha 2 M high levels of this are shown contrasting with progressively lowered antithrombitic action. These paradoxes no doubt arise from the fact that neonatal haemostasis is analysed using standardised techniques and reactions which were developed for adult haemostasis, from which it is certainly as different as from those of other animals. Neonatal haemostasis is perfectly balanced in normal conditions. Important changes occur however in respiratory distress where there is a drop in factor V and soluble complexes appear, bringing about rough shapes suggestive of the subclinical syndrome of defibrination. This situation will be further developed in a forthcoming article.

An unusual case of sudden, fulminant pneumococcemia and disseminated intravascular coagulation occurred in a woman who had had incidental splenectomy 8 months previously, at the time of gastrectomy for duodenal ulcer. Similar cases in which there is constant relationship of splenectomy, pneumococcal sepsis, and Waterhouse-Friderichsen syndrome have been documented. Other similarities which are notable are a tendency for the disease to occur in women, lack of a nidus of infection, and proliferation of diplococci to numbers great enough to be seen easily on the peripheral blood smear.
