Disseminated intravascular coagulation (DIC)
is a pathologic condition associated with critical illnesses, including sepsis. Recent studies have suggested that endogenous cytokines and leukocytes are involved in major roles of its pathophysiology. We report a case of sepsis-induced
DIC
due to
pneumonia
that was associated with diffuse and selective thrombosis in pulmonary arteries, yielding to sudden death from pulmonary massive embolism. This report suggests that the selective and lethal pulmonary thromboembolism progresses under the standard therapies in sepsis-induced
DIC
.

We report a 85-year-old woman who had an onset of gait disturbance at 80 years of the age. She had a dizzy spell when she was 80-year-old. She was evaluated at another hospital where paroxysmal tachycardia and sinus arrest lasting as long as 5.8 seconds were found. She was diagnosed as having sick sinus syndrome and a pace maker was inserted. She had a gradual onset of disturbance of gait shortly after the above dizzy spell. She became unable to walk fast and her steps became small. Neurologic examination at age 83 revealed small step gait with freezing episodes. Retropulsion was present. No motor weakness or origidity was noted. She had no tremor. Mentally she was alert and sound. Cranial nerves were essentially normal. Cranial CT scan revealed slight diffuse low density change in the bilateral cerebral white matter. She was treated with amantadine HCI and levodopa with carbidopa. Her gait and balance showed some improvement. She developed
pneumonia
and worsening of her gait when she was 85 years of the age, and she was admitted again to our hospital. She was mentally alert and sound but she showed marked freezing of gait with loss of postural reflex; she would have fallen down unless supported upon standing. Cranial nerves were again essentially normal. Her hospital course was complicated by
pneumonia
,
DIC
, and renal failure. She expired suddenly on the 10th day of her last admission. She was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had vascular parkinsonism due to lacunar state. However, paucity of vascular changes in her CT scan remained as a question. Other participants thought that she had nigral cell loss secondary to her aging and circulatory disturbance which would have been caused by her sick sinus syndrome. Post-mortem examination revealed marked loss of nigral pigmented cells; the cell loss was diffusely seen in the substantia nigra. Neurofibrillary tangles were seen in the remaining neurons. In addition, gliosis was noted in the globus pallidus and the subthalamic nucleus, however, neuronal loss was very mild in those nuclei. In the superior colliculus, neuronal loss was mild, however, gliosis was seen. No clear neuronal loss was observed in the locus coeruleus, however, Lewy bodies were seen in the remaining neurons. Furthermore, Lewy bodies were also found in the substantia sigra. It was thought that she had progressive supranuclear play (PSP). Question was whether or not she was complicated by Parkinson's disease. Clinically, she had no rigidity or tremor. Pathologically, locus coeruleus did not show neuronal loss. Therefore, incidental Lewy body disease was raised as a possibility. Finally, it should be pointed out that she had no oculomotor disturbance or dementia, yet she had PSP. Her clinical features were those of pure akinesia. Pathologic changes were also relatively mild except for those in the substantia nigra. Possibility of post-encephalitic parkinsonism without encephalitis was also discussed, however, over all distribution of her pathologic changes was more consistent with PSP.

This study was undertaken to correlate the clinical features and pathologic changes noted during the initial and later stages of fatal typhoid illness. Five cases who died during the initial stage of the illness (< 2 weeks from onset) had altered mental status, tachypnea, and tachycardia. Three had shock and elevation of serum creatinine values. Autopsies of all five revealed hyperplastic Peyer's patches, features of adult respiratory distress syndrome, and megakaryocytosis. Five other cases died during the later stage of the illness (> or = 2 weeks after onset). They had a left shift in peripheral blood leukocyte count. Autopsies revealed deep ileal ulcerations with or without perforation and peritonitis and intercurrent
pneumonia
. Three of them had
disseminated intravascular coagulation
. Further studies are warranted to understand the mediators of shock and tissue injuries during the initial period of the illness.

Changes of endotoxin in plasma, and the response of the coagulation system and blood cells in septicemia of Haemophilus parasuis infection were examined by inoculation with H. parasuis in specific pathogen-free (SPF) pigs. Eight pigs were inoculated intratracheally with 10(5), 10(6) and 10(7) colony formation units (CFU) of the strain Nagasaki (serovar 5). All pigs died 28 to 42 hr after inoculation. Haematologically, severe leukopenia occurred 24 hr post inoculation (hpi) until death. Glucose concentration decreased from 24 hpi to death. In the coagulation system, decrease of platelet counts, prolongation of prothrombin time, activated partial thromboplastin time, and increase of fibrinogen-fibrin degradation products were observed in all inoculated pigs. Endotoxin was detected in the plasma of all the inoculated pigs from 16 hpi to death, and its concentration rose dramatically just before death. H. parasuis was re-isolated from the blood of all inoculated pigs from 16 hpi to death, and also from almost all organs and body fluids of the pigs. The pigs had microthrombi in the kidney, liver and lungs, and many also had
pneumonia
, meningitis and serositis. H. parasuis antigen was detected in the lesions by the immunoperoxidase technique. The results indicated that
disseminated intravascular coagulation
(
DIC
) and endotoxin shock involved aggravation of clinical signs and death on the pigs induced to septicemia of H. parasuis.

Pneumonia
is the most common serious complication of varicella infection in adults. A variety of thrombotic complications including purpura fulminans and
disseminated intravascular coagulation
have been reported in children with varicella but not in adults. Two men with varicella
pneumonia
who had profound lower extremity ischemia caused by thrombosis of the profunda femoris and tibial arteries are reported. Both patients had free protein S deficiency and vascular thrombosis in association with varicella
pneumonia
without overt evidence of
disseminated intravascular coagulation
or purpura fulminans. Antiphospholipid immunoglobulin G and immunoglobulin M antibodies were present in one, whereas the other had evidence of the lupus anticoagulant. The proposed pathogenesis and management options including intraarterial thrombolytic therapy with urokinase and the need for long-term anticoagulation are discussed.

Legionellosis is an important cause of severe
pneumonia
in the community. Inadequate therapy will lead to respiratory distress syndrome,
disseminated intravascular coagulation
(
DIC
) and finally fatal multiple organ failure. We encountered a rare case in which early manifestation included septic shock and
DIC
complicated by acute myocardial infarction (AMI) suspected to be derived from Legionnaires' disease. A 54-year-old healthy female complained of lumbago, high fever and dry cough 10 days after visiting a hot spring spa. She was emmergently admitted due to shock. Physical examination demonstrated hypotension, high fever, course creakle in the right lower lung. Hepatosplenomegaly, lymphadenopathy and eruption were not found. WBC count was 34600/microliters with nuclear shift. CRP elevated. FDP, D dimer and TAT also elevated CPK elevated with dominance of the MB isozyme. Chest roentogenography revealed congestive heart failure, pleural effusion and obscure pneumonic shadow and EKG showed ST segment elevation in leads I, II, III, aVF, V4, V5, and V6. The patient was diagnosed as having septic shock,
DIC
and AMI. She was treated with gabexate mesilate, high dose methyl prednisolone and dopamine hydrochloride as well as piperacillin, meropenem, isepamycin and fluconzaole. Despite intensive care, the blood pressure fell again and
pneumonia
had progressed on the 8th hospital day. These antibiotics appeared to be ineffective. Erythromycin was then administered and a dramatic effect. was obtained as the patient recovered. Serum titer of Legionella pneumophila (serogroup 1) rose to 128-fold 2 weeks after the onset. Other serum titers such as Chlamydia psittaci, Rickettsia, Mycoplasma were all negative. Cultures obtained from the sputum, throat swab, urine and blood did not yield any microorganisms. Although the diagnosis could not be confirmed because the titer did not elevate over 256-fold of 4-fold within 2 weeks after the onset, Legionella infection was highly suspected from the clinical features. This is a rare case in which septic shock and
DIC
with AMI preceded pulmonary symptoms in a non-immunocompromised patient.

The causative organisms, clinical manifestations, factors influencing prognosis, and other epidemiological characteristics of 81 episodes of bacteremia due to gram-negative organisms, in non-neutropenic patients, were studied retrospectively during a 3-year period (1992-1994) at the Department of Internal Medicine of the University Hospital of Heraklion, Crete, Greece. The gram-negative bacteremia incidence was 2% and the overall mortality 12%. All 81 patients had fever; Escherichia coli was the most frequent organism isolated (from 47 patients--58%) and was associated with shock (9/47),
disseminated intravascular coagulation
(
DIC
) (8/47), anuria (5/47), adult respiratory distress syndrome (ARDS) (3/47), and
pneumonia
(1/47). Other less frequent gram-negative microorganisms were Klebsiella spp. (ten patients; 12%), Pseudomonas spp. (7; 7%), Salmonella spp. (5; 6%), Enterobacter spp. (5; 6%), Proteus spp. (3; 3.4%), Stenotrophomonas spp. (3; 3.4%), and Acinetobacter spp. (1; 1.2%). ARDS. shock,
DIC
, anuria, presence of central venous catheter, urinary catheter, unknown origin of infection and inappropriate treatment were significantly associated with a higher death rate. Early initiation of appropriate therapy was the most important intervention that favorably affected the outcome of gram-negative bacteremias in this patient population.

We evaluated the clinical data in 83 patients with sepsis, which was diagnosed by both Bone's definition of sepsis and positive isolates from blood culture, according to their underlying diseases. This study enrolled a total of 117 septic episodes in 83 patients (57 males and 26 females, mean age: 52.0 years). We classified 3 groups, including hematological malignancies (46 patients, 72 episodes), solid malignant tumors (23 patients, 25 episodes) and non-malignancies (14 patients, 20 episodes), by the underlying diseases. Of the total number of isolates from blood culture, 53.0% were single gram-positive bacteria, 33.3% were single gram-negative bacteria, 7.7% were single fungus and 6.0% were polymicrobial organisms. In addition, coagulase negative staphylococci was isolated most often in patients with hematological malignancies. Sepsis was often caused by infectious focuses of hemorrhoid, stomatitis or intravenous catheter in patients with hematological malignancies, by
pneumonia
in patients with solid malignant tumors and by urinary tract infection in patients with non-malignancies. Mortality of sepsis in patients with solid malignant tumors (48%) was highest in 3 groups. Septic patients, who were complicated with shock and/or
DIC
, has poor prognosis in all groups. Serum albumin level was significantly lower in dead patients than patients who survived. These results suggest that clinical features may be different according to the underlying diseases of patients with sepsis.

Because of the critical role of neutrophils in host defenses, it was hypothesized that stimulation of neutrophil production and function with Filgrastim would improve the outcome of hospitalized patients with community-acquired
pneumonia
. To test this hypothesis, a randomized, placebo-controlled, multicenter trial of Filgrastim (300 micrograms/day up to 10 days) as an adjunct to antibiotics was conducted for these patients. Outcome measures included time to resolution of morbidity (TRM, a composite measure of temperature, respiratory rate, blood oxygenation, and chest radiograph), 28-day mortality, length of stay, and adverse events. Filgrastim increased blood neutrophils 3-fold, but TRM, mortality, and length of hospitalization were not affected. Treatment, however, accelerated radiologic improvement and appeared to reduce serious complications (e.g., empyema, adult respiratory distress syndrome, and
disseminated intravascular coagulation
). Filgrastim administration was safe and well tolerated in these patients. Additional trials are needed to establish the value of this approach to treatment of infectious diseases.

Severe pneumococcal
pneumonia
may precipitate both respiratory failure and neutropenia. The prognoses are considered to be very poor in such cases. We encountered three patients with pneumococcal
pneumonia
presenting respiratory failure and neutropenia, and successfully treated two. All three patients showed
disseminated intravascular coagulation
, and respiratory failure requiring mechanical ventilation. Neutropenia was treated with granulyte-colony stimulating factor (G-CSF), with methylpredonisolone administered by pulse therapy for 3 days to treat severe respiratory failure during the clinical course. All 3 patients were relieved of their respiratory failure at least for a few days following treatment. As a result of treatment with antibiotics and G-CSF, pneumococci disappeared from the patients' sputum. However, it has been reported that disintegration of the bacterial cell walls can release inflammatory components capable of causing secondary inflammatory reactions in the lung tissue. This suggested that the worsening respiratory failure experienced by our patients during their clinical course was a result of such reactions, and that methylpredonisolone was effective as the treatment of inflammation.
