A 73-year-old man who had been receiving treatment for hypertension and angina pectoris was admitted to hospital following a transient ischemic attack. He was diagnosed as having chronic disseminated intravascular coagulation (DIC) complicated by a thoracoabdominal aortic aneurysm, and was treated with heparin sodium and a protease inhibitor. Although the DIC was controlled, the patient had to remain hospitalized in order to receive the medication by continuous infusion. Therefore, the heparin sodium and protease inhibitor were replaced by camostat mesilate, a drug suitable for oral administration and widely used for treatment of chronic pancreatitis. The drug proved effective for the chronic DIC, thus allowing the patient to receive regular treatment on an outpatient basis, and improving his quality of life.

Placental abruption is due to the rupture of the uterine spiral artery. The placenta separates totally or partially from the uterine wall during pregnancy. This serious syndrome has a great risk for the mother (shock and disseminated intravascular coagulation) and her child (mortality or morbidity). To the known risk factors like hypertension, the use of cocaine and smoking, homocysteine is recognized as an independent risk factor for vascular disease and endothelial dysfunction. In contrast to normal pregnancy where the spiral artery endothelium is replaced by trophoblast, the endothelium persists in case of placental abruption. In 165 women with placental vasculopathy and 139 matched controls hyperhomocysteinemia resulted in an odds ratio of 4.7 (95% CI: 1.6-14.0). The C677T mutation gave a risk of 2.5 (95% CI: 1.0-6.0). Even up to 2 or 3 years post-partum evidence could be found of endothelial dysfunction. The combination of hyperhomocysteinemia and thrombotic factors like APC resistance, Protein-C, Protein-S, antithrombin and factor V Leiden increases the risk of placental abruption 3-7 times. The common denominator of the effect of homocysteine on blood vessels could be sited in the process of proliferation of cells that need proper methyl groups for proper function (DNA synthesis and expression). These methyl groups are delivered by D-adenosylmethionine formed from methionine after remethylation of homocysteine. The coagulation factors and plasma homocysteine values can be modulated by vitamins, folic acid and folates in particular. To prove the clinical value of folate supplementation placebo-randomized trials are urgently needed: for placebo to be started after the period of neural tube closure.

Intravascular lymphoma (IVL) is a rare aggressive disease characterised by the presence of lymphoma cells only in the lumina of small vessels, particularly capillaries. Only about 200 cases have been reported in the world (some of them retrospectively). IVL is predominantly of B-cell lineage origin but occasionally T-cell lineage occurs. Multiple organs may be involved and a variety of clinical presentations have been described. These include nephrotic syndrome, pyrexia and hypertension, breathlessness and haemolytic anaemia, leukopoenia, pancytopoenia and disseminated intravascular coagulation. We report a case of a 38-year-old woman with a highly aggressive clinical course of IVL. She was admitted to the Department of Neurosurgery because of spondylolisthesis of L5-S1 qualified to surgery. During hospitalisation haemolytic anaemia, thrombocytopoenia and splenomegaly were observed and she was admitted to the Department of Haematology for diagnosis. During her staying in the hospital, new symptoms, such as kidney and liver failure, occurred and the central nervous system was involved. The clinical course was very rapid and progressive. Corticosteroid therapy was started but the disease soon led to the fatal outcome. Diagnosis was established at post-mortem examination.

A 32-year-old Japanese man was hospitalized for evaluation of unconsciousness. He was diagnosed as having primary pulmonary hypertension (PPH) with severe systemic hypertension, Raynaud's phenomenon and relative polycythemia. Hemostatic studies revealed increased coagulation and decreased fibrinolysis, similar to findings of chronic disseminated intravascular coagulation (DIC). Although activation of coagulation and systemic hypertension were improved after treatment with phlebotomy and administration of nifedipine, enerapril and warfarin, pulmonary hypertension was unchanged, suggesting that irreversible change had already occurred in the pulmonary arteries. Those complications could modify the process of pulmonary hypertension by inducing a hyperviscosity state.

An hemorheological study on whole blood filterability (WBF) was done in eleven patients bearing of sudden deafness, in a continuous way, even before clinical onset. This evaluation is making usually in animal models, but not in humans. Independently of clinical diagnosis of each patient (two cases of diabetes mellitus, one of ulcerative colitis, systemic lupus erythematosus, systemic hypertension, after blood transfusion, sepsis with disseminated intravascular coagulation, upper respiratory ways infection, after surgery, and two healthy individuals), all of them showed a decreased WBF when hearing loss appeared (from 19.97 +/- 1.15 microliters/sec to 16.87 +/- 1.21 microliters/sec). This value normalized at six or seven days from the onset in cases with some kind of hearing recovery (18.83 +/- 1.01 microliters/sec, n = 4), but did not in those with no improvement even at thirty days (17.39 +/- 0.77 microliters/sec, n = 7). There were differences in WBF values of patients with and without hearing recovery in determinations at seven and thirty days from onset. Decrease in WBF accompanies this hearing disorder and confirms the cochlear microcirculation susceptibility to the impairment of blood viscoelastic properties.

A 79-year-old man with herpes zoster was referred to our hospital for pain control. He was a survivor of the atomic bombing of Hiroshima, and had a history of cerebral infarction and hypertension. A cervical epidural catheter was placed for continuous analgesic infusion. After 20 days of catheterization, he gradually developed a high fever and confusion, and complained of nausea and headaches. An urgent blood examination revealed a white blood cell count of 15,200 mm-3 and a C-reactive protein of 32.4 mg.dl-1. The catheter was removed and antibiotic therapy was started. Repeated magnetic resonance imaging could not confirm epidural abscess formation. The bacterial culture of the cerebrospinal fluid was negative, but the cultures of the blood, the catheter tip, and the nasal cavity swab were positive for methicillin-resistant Staphylococcus aureus. Although intravenous vancomycin was administered, systemic inflammation persisted. The patient consecutively suffered varied disorders such as acute renal failure, disseminated intravascular coagulation, and gastrointestinal bleeding. Although symptomatic treatment had been prolonging his life, 58 days after the catheter removal, the patient suddenly developed cerebellopontine infarction, which made mechanical ventilation necessary. He remained unconscious until his death 117 days after the catheter removal. We discussed the possible pathogenetic mechanisms of the present case.

A 75-year-old man presented with a rare case of chordoma in the sella turcica of the skull base. He had been treated for hypertension and chronic renal failure since 1990. Computed tomography detected a tumor in the sella turcica in 1994, but the patient had no clinical complaints and the serum pituitary hormone levels were normal. He died of disseminated intravascular coagulation, myocardial infarction, pulmonary infection, and multiple cerebral infarctions in 2000. At autopsy, the tumor in the sella turcica was 3.1 cm in greatest diameter and had compressed the pituitary gland posteriorly. Histological examination found oval cells and vacuolated short spindle-shaped cells which showed morphological changes similar to myxoma cells. The tumor was lobulated by narrow connective tissues. The tumor did not contain any cartilaginous tissue components, and was stained positively for epithelial membrane antigen but negatively for S-100 protein. The final diagnosis was chordoma. There was no association between the tumor and the cause of death.

A central position in the development of systemic inflammation is played by activation of the vascular endothelium and monocyte- macrophage system. Both are associated with the formation of inflammatory cytokines, the primary mission of which is mobilization of the organism to cope with the infection. The so-called acute stage response develops with typical clinical manifestations and laboratory values. When it is impossible to stop the inflammation the syndrome of systemic inflammatory response develops with excessive activity of inflammatory cytokines and immune mechanisms. This apparently favourable system can be highly toxic for the organism and can lead to the syndrome of multiorgan failure, to disseminated intravascular coagulation, to depression of the myocardium, refractory vasodilatation, hypertension and septic shock. The compensatory antagonistic mechanism which develops due to the formation of anti-inflammatory cytokines leads sometimes to the development of a balanced state of immunity which is most favourable from the prognostic aspect. In case of their excess however immunodepression develops which is equally dangerous for the patient as excessive cytokine activity. From what has been said ensues the need of regular monitoring of patients with sepsis and thus also detailed investigation of their immune system.

A case of 31-year old woman who underwent emergency caesarean section (CS) following suspicion of the HELLP syndrome was reported. She developed arterial hypertension in 33rd week. In 38th week of her gestation elevated liver enzymes and positive albumin in urine were reported and pathological flow in umbilical artery and fetal aorta was found on ultrasound. The HELLP score was 12 and the HELLP syndrome was diagnosed. The pregnancy was terminated by CS for fetal distress and the HELLP syndrome. Two hours after the section she developed massive uterine bleeding with the signs of hemorrhagic shock. Despite of replacement therapy laboratory data worsened. DIC was diagnosed. Recombinant factor VIIa was administrated; after several minutes bleeding decreased and laboratory data normalized.

A 35-years old gravida IV and para II underwent caesarean section because of fetal distress following induction of labour. During operation the patient developed disseminated intravascular coagulation (DIC), severe haemorrhage and shock necessitating massive blood transfusion,hysterectomy with pelvic packing, and high-dose catecholamines. Ultimately, recombinant factor VIIa was given to control bleeding. During the first 24 hours after operation, both clinical and laboratory findings showed that the severe DIC was on the course to recovery.However, the patient subsequently developed multiple organ dysfunction syndrome with respiratory and renal failure requiring mechanical ventilation and haemodialysis.All therapeutical efforts could not help that the patient passed away due to an inevitable multiple organ failure on the 12th day after the operation. Given the constellation of diagnostic and clinical findings, the most likely diagnosis was amniotic fluid embolism (AFE), a rare complication of pregnancy. The following differential diagnoses were less likely or excluded in this reported patient: pre-eclampsia/pregnancy-induced hypertension,HELLP syndrome,anaphylaxis,uterine rupture, transfusion reactions,pulmonary embolism. AFE occurs rarely, and because studies in animal models cannot reproduce accurately the pathophysiological and clinical alterations seen in humans, its pathogenesis remains unclear. It has been proposed that the clinical syndrome of AFE occurs when fetal antigens pass the maternal immunological barrier in susceptible mothers. The recognition of fetal antigens by maternal immune system subsequently triggers the release of endogenous mediators that are responsible for dramatic pathophysiological disturbances.Furthermore, the components of amniotic fluid initiate the DIC. These events are more consistent with septic shock and anaphylactic shock than with an embolic process and it was proposed that the term "amniotic fluid embolism" be changed to "anaphylactoid syndrome of pregnancy". At present, no therapy has been found to consistently improve outcomes in women with AFE.Patients who survive the initial insult are at high risk for multiple organ failure. The mortality of AFE remains high.
