A 57-year-old woman with a 7-year history of Parkinson's disease was admitted to our hospital because of a high fever, disturbance of consciousness, increased muscular rigidity, tachycardia and hyperhidosis after she stopped taking her prescribed levodopa + carbidopa (Menesit) 400 mg/day. In the laboratory examinations, the erythrocyte sedimentation rate was 109 mm/h, thrombocytes 7.8 x 10(4)/mm3, fibrinogen 457 mg/dl, FDP 74.8 micrograms/dl, thus suggesting
disseminated intravascular coagulation
(
DIC
). According to her biochemical examination, the serum AST (253 IU/l),
ALT
(178 IU/l), CK (7115 IU/l) and BUN (25 mg/dl) levels were all increased. These laboratory data and the clinical course indicated the patient to be suffering from neuroleptic malignant syndrome (NMS) with
DIC
. She was diagnosed to have NMS associated with
DIC
. She was treated with dantrolene sodium, bromocriptine, and gabexate mesilate, and her symptoms thereafter gradually improved. On day 7, she developed status epilepticus in spite of the clinical improvement in her symptoms of NMS and
DIC
including a clouding of consciousness. The status epilepticus was also attenuated by the use of thiamylal sodium. Patients with Parkinson's disease associated with NMS are considered to have a low incidence of
DIC
, status epilepticus, and in Japan this may be the first case report of the successful treatment of NMS with
DIC
and status epilepticus in a patient with Parkinson's disease.

A 66-year-old male was admitted to our hospital, presenting a high fever and generalized erythema on June 9, 1999. Physical examination revealed many eschars on his legs. Laboratory examinations were as follows: platelet counts, 5.5 x 10(4)/microliter: FDP, 25 micrograms/ml: TAT, 70.9 ng/ml: GOT, 177 IU/l,
GPT
, 174 IU/l: CRP, 32.3 mg/dl. Based on these findings, he was diagnosed as having rickettsiosis with
DIC
, and minocycline (200 mg/day) and heparin were started immediately, but had no clinical effect for 3 days. Blood gas analysis showed severe hypoxia and the chest CT scan revealed increased CT value in all lung fields with reticular shadows in the lower fields and pleural effusion, suggested interstitial pneumonia. Methyl-prednisolone pulse therapy was started on June 12, after which he completely recovered. Anti-Rikettia japonica IgM antibody was found to be x8,192 by immunofluorescent test, establishing the diagnosis of Japanese spotted fever. Acute respiratory failure with interstitial pneumonia shadows should be emphasized as a complication of severe rickettsiosis.

Use of hyperthermia in the treatment of cancer and viral infection has received renewed interest. However, the in vivo relationship between hyperthermia and direct versus indirect effects upon hemostasis are incompletely defined, although we do know that
disseminated intravascular coagulation
(
DIC
) is a common sequel to heat stroke. The purpose of the present study was to more precisely define the relationship between hyperthermia and derangements of hemostasis, thereby providing a guideline for the development of safe hyperthermia treatment regimens. The present investigation examined the in vivo effects of high-grade whole-body hyperthermia (WBH) (42.5 degrees C, 90 min) on hemostasis in a canine model. Induction of hyperthermia via extracorporeal circulation of heated blood (ECC-WBH) caused thrombocytopenia, increased plasma fibrin degradation products (FDPs), prolonged clotting times, increased serum liver enzymes, and evidence of spontaneous bleeding. However, when WBH was induced by peritoneal lavage (PL-WBH), transient thrombocytopenia was the only significant alteration. Temporal correlation between hemostatic alterations and elevations in serum
alanine aminotransferase
(
ALT
) levels in the ECC-WBH treatment group suggested that liver injury is responsible, at least in part, for the coagulopathy associated with high-grade hyperthermia and that in the absence of liver injury, identical degrees of hyperthermia cause only incidental decreases in platelet numbers.

The effect of urinary protein C inhibitor (uPCI) on
disseminated intravascular coagulation
(
DIC
) was investigated using an experimental
DIC
in rats. uPCI (0.5 and 1.0 mg/kg) was continuously administrated into the left femoral vein of the rats with lipopolysaccharide (50 mg/kg)-induced
DIC
. In all doses, uPCI significantly prevented the drastic changes in the parameters such as fibrinogen concentration, activated partial thromboplastin time (APTT), prothrombin time (PT), fibrin/fibrinogen degradation products (FDP) level, aspartate amino-transferase (AST) level and
alanine aminotransferase
(
ALT
) level. Furthermore, uPCI significantly inhibited the increase in the levels of plasma kallikrein and thrombin which act not only as the procoagulant proteases but also as the chemotactic factors to neutrophils and monocytes. These results show that uPCI may prevent hypercoagulation, the induction of secondary fibrinolysis and organ failure in the
DIC
model. Therefore, uPCI may be a useful agent for the clinical treatment of
DIC
.

We compared urinary protein C inhibitor (uPCI) with low molecular weight heparin (LMWH) in terms of the effect on the pathophysiology of
disseminated intravascular coagulation
(
DIC
), such as hypercoagulation, induction of secondary fibrinolysis and organ failure, using lipopolysaccharide (LPS)-induced
DIC
in rats. The uPCI (0.5 and 1.0 mg/kg) administration significantly inhibited both the decrease in fibrinogen level and the increase in fibrin/fibrinogen degradation products (FDP) level, and the effects compared favorably with those of LMWH (100 and 200 IU/kg). Both uPCI (0.5 and 1.0 mg/kg) and a low dose of LMWH also inhibited the increases in the levels of aspartate aminotransferase (AST),
alanine aminotransferase
(
ALT
), thrombin, and plasma kallikrein equally, but a high dose of LMWH did not inhibit the changes in those parameters. Furthermore, uPCI dose-dependently prevented the prolongation of activated partial thromboplastin time (APTT), while LMWH excessively prolonged APTT at a high dose. These results suggest that the preventive effect of uPCI on the pathophysiology of
DIC
compares favorably with that of LMWH, including the lack of a hemorrhagic reaction in contrast to LMWH.

Protein C is the zymogen of an anticoagulant serine protease and is converted to its active form (activated protein C: APC) by thrombin in the presence of thrombomodulin. APC plays an important role in regulating coagulation and fibrinolysis by inactivating not only blood coagulation factors Va and VIIIa but also type-1 plasminogen activator inhibitor (PAI-1). The aim of the present study was to examine the effect of a human APC product (designated as CTC-111), compared with that of heparin, on the
disseminated intravascular coagulation
(
DIC
) induced by lipopolysaccharide (LPS) in rats. LPS (1 mg/kg/h) infusion was performed through a femoral vein for 4 h. One-fifth amount of the total dosage of CTC-111 or heparin was injected into the other femoral vein, followed by a 4-h infusion of the remainder. Both CTC-111 (10,000-100,000 U/kg) and heparin (400-800 IU/kg) inhibited the decrease in platelet count and fibrinogen level equally. The prolonged activated partial thromboplastin time and prothrombin time observed in
DIC
rats were further elongated in both CTC-111- and heparin-treated rats. But, this prolongation was less in CTC-111-treated rats than in the heparin-treated ones. Heparin inhibited the increase in fibrin and fibrinogen degradation products more prominently than CTC-111. On the other hand, CTC-111 strongly inhibited the increase in PAI-1 activity but heparin did not. These results suggest that CTC-111 may enhance fibrinolysis through its direct inhibitory effect on PAI-1. The parameters for liver or renal damage, i.e., plasma glutamic-oxaloacetic transaminase (GOT),
glutamic-pyruvic transaminase
(
GPT
), creatinine (Cre) and blood urea nitrogen (BUN), were significantly increased by LPS infusion. Both CTC-111 (100,000 U/kg) and heparin (800 IU/kg) decreased the increase in GOT and
GPT
levels significantly, whereas neither affected the increase in Cre or BUN. From these results, the activation of the blood coagulation system might partially contribute to the progression of liver damage caused by LPS, and might be less involved in the progression of renal damage in this model. In conclusion, CTC-111 showed both anticoagulant and profibrinolytic activity in the LPS-induced
DIC
model without excessive prolongation of coagulation time. From these results, CTC-111 is expected to be a useful remedy for
DIC
without the risk of bleeding.

Clinical features of tsutsugamushi disease (scrub typhus) were analyzed, based on 416 cases reported in Japan in 1998. Three major clinical symptoms: eschar, fever and rash were found in 87%, 98% and 92% of the cases, respectively. Elevated levels of CRP, GOT,
GPT
and LDH were observed in 96%, 85%, 78% and 91%, respectively. These clinical and laboratory findings were observed in the majority of the cases and considered important for diagnosis.
Disseminated intravascular coagulation
developed in 21 cases, indicating that scrub typhus can be life threatening. Lymphadenopathy was observed in 51% of the cases. Enlarged lymph nodes were limited to the local sites in 75% of these lymphadenopathy cases and most of these sites were adjacent to eschars. Most eschars were scabbed and located in the abdomen and the lower half of the body, especially the feet. This suggests that these parts are frequently exposed to tsutsugamushi mites. Furthermore, the skin is soft in these parts and covered by cloth. These factors may make it possible for mites to keep biting without being noticed for several hours, long enough for rickettsial transmission. Interestingly, eschar and rash were absent in 14% and 8% of the cases, respectively. This result suggests that the cases without the unique symptoms may have been misdiagnosed as common cold or other febrile illnesses. One hundred and fifty-four suspected cases were not scrub typhus cases by the serological tests. The three major clinical symptoms were present in approximately a half of these negative cases, eschar being observed in approximately 70%. This may suggest the presence of new type of scrub typhus can not be diagnosed by the present laboratory tests. Clinical features of scrub typhus in Japan were well revealed, and information obtained in the present study is useful for improving clinical diagnosis. It should, however, be stressed that there were cases that could not be correctly diagnosed only by the clinical symptoms, suggesting that it is important to improve the serological tests.

Surveillance for scrub typhus was conducted in Japan in 1998 using a questionnaire. A total of 462 cases were reported. Scrub typhus occurred in both the fall and spring in the northern part of Honshu (the main island), and in the fall in the central part of Honshu and on the island of Kyushu. The occurrence of the disease varied with age, gender, and activity. Seventy-six percent of the patients were more than 51 years old, and 36% and 16% of the patients were engaged in farm work and forestry, respectively. Fever, rash, and eschar were detected in 98%, 93%, and 97% of the patients, respectively. Elevated levels of C-reactive protein, aspartate transaminase, and
alanine transaminase
were detected in 96%, 87%, and 77% of the patients, respectively.
Disseminated intravascular coagulation
developed in 34 cases and had a unique regional distribution. This study shows the status of scrub typhus in Japan in 1998 and provides important information for diagnosis and prevention.

A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU,
ALT
41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve.
Disseminated intravascular coagulation
syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

We investigated the relationship between endothelin, a potent vasoconstrictor peptide, and the pathophysiology of
disseminated intravascular coagulation
(
DIC
), using two models of
DIC
. Experimental
DIC
was induced by sustained infusion of 50 mg/kg lipopolysaccharide (LPS), or 3.75 U/kg thromboplastin, for 4 h via the rat tail vein. The effect of administration of a non-selective endothelin receptor antagonist (TAK-044) (2, 10, or 50 mg/kg, from -0.5 to 4 h) on thromboplastin-induced
DIC
was not significant. However, LPS-induced elevation of
alanine aminotransferase
, creatinine and glomerular fibrin deposition was significantly suppressed by co-administration of TAK-044 in a dose-dependent manner, although no effect of TAK-044 was observed on the platelet count, fibrinogen concentration or the level of thrombin-antithrombin complex. Moreover, plasma levels of D-dimer, which reflect the grade of fibrinolysis of cross-linked fibrin, were significantly increased by co-administration of each dose of TAK-044 in the LPS-induced
DIC
model in rats. Our results suggest that vasoconstriction, as well as depressed fibrinolysis, contribute to severe organ dysfunction in LPS-induced, but not thromboplastin-induced,
DIC
, and that endothelin plays a role in the development of organ injury in LPS-induced
DIC
in rats.
