We examined plasma levels of activated factor VII (F VIla) in 50 patients positive for lupus anticoagulant (LA), in 83 patients negative for LA, and in 10 healthy volunteers as controls. Plasma F VIIa was present in healthy volunteers; its level was significantly increased, compared to the level in the controls, in patients with thrombosis, collagen diseases, and disseminated intravascular coagulation (DIC), suggesting that it reflected a thrombotic state. Plasma F VIIa was correlated with thrombin-antithrombin complex (TAT) in patients negative for LA but showed no such correlation in those positive for LA. Plasma F VIIa was negatively correlated with activated partial thromboplastin time (APTT) in patients positive for LA, but not in those negative for LA, suggesting that LA could inhibit the F VIIa assay system. Plasma F VIIa level was significantly increased in patients with thrombotic diseases; however, in patients positive for LA, it is possible that increased plasma F VIIa level may not be correlated with thrombogenicity.

A 41-year-old woman with complete protein S (PS) deficiency who developed diffuse proliferative lupus nephritis is reported. She was referred to our hospital with nephrotic syndrome and thrombocytopenia. Her medical history included colorectostomy and amputation of the extremities because of repeated thrombotic episodes during her teens without any evidence of systemic lupus erythematosus. The diagnosis of PS deficiency was made from the patient's clinical course, undetectable serum PS in either the active or inactive form, normal protein C activity, and no evidence of the antiphospholipid syndrome. However, there was no definitive family history. A depressed level of complements and a positive antinuclear acid antibody suggested a diagnosis of systemic lupus erythematosus. The patient had a rapidly progressive course and died of disseminated intravascular coagulation. An autopsy showed generalized thrombotic lesions and diffuse proliferative lupus nephritis on both ordinal light and immunoperoxidase microscopy. Our observations suggest that PS-deficient patients may have a hyperinflammatory response.

Colitis in systemic lupus erythematosus (SLE) poses a diagnostic challenge as clinical, radiological and laboratory findings are often non-specific. Fulminant amoebic colitis is a rare cause of death in SLE. Early diagnosis coupled with timely surgery can reduce the mortality. The demonstration of haematophagous trophozoites in the stool is diagnostic but insensitive. Early endoscopy with adequate specimen collection is an important part of the diagnosis. Serology is both sensitive and specific but can take up to 2-4 weeks for seroconversion making it less useful in a disease that takes a rapid downhill course if treated inappropriately. We report a fatal case of colitis in a patient with SLE due to invasive amoebiasis which was complicated by Salmonella bacteraemia, disseminated intravascular coagulation, acute oliguric renal failure and adult respiratory syndrome. We also reviewed the literature on the clinical features and diagnosis of fulminant amoebic colitis. Amoebic colitis, although rare, should be considered in the differential diagnosis of lupus patients with colitis.

Human parvovirus B19 (HPV-B19) has been known as the etiologic agents of erythema infectiosum in normal childhood, and chronic anemia and thrombocytopenia in immuno-compromised patients. Recently, this virus has been reported as the association with rheumatic manifestation such as rheumatoid arthritis and systemic lupus erythematosus (SLE). We described here a patient whose HPV-B19 infection was mimiking atypical symptoms of SLE at diagnosis, and was persistent because of immuno-suppressive therapy for SLE. A 34-year-old female was admitted to our hospital on 22 June 1995, presenting fever episode and cervical lymph node swelling. Before eighteen months, she was received methyl-predonisolone pulse therapy and plasma exchange by fresh frozen plasma for the treatment of Stevens-Johnson syndrome, and after several weeks these therapy she was suffered from viral infection with lymphadenopathies with a transient appearance of atypical lymphocytes in her peripheral blood smear. On laboratory examination at the present admission, her peripheral blood showed anemia, thrombocytopenia with atypical lymphocytes. Throughout her hospitalization, anti-nuclear antibody (ANA) suspected SLE including anti-DNA and anti-Sm antibody were all negative except of transient week positive ANA screening test. Her physical condition presented poor clinical course with fever elevation, increased ascites and renal dysfunction showing the elevation of CRP and circulating immune-complex (Clq binding method). Her serum was positive for IgM and IgG antibody against VP-1 and VP-2 antigen of HPV-B19 by ELISA in April 1996. And then, HPV-B19 DNA by polymerase chain reaction (PCR) was positive in bone marrow sample in March 1996, and also positive in spleen necropsy at death. We confirmed persistent chronic HPV-B19 infection by measurement of HPV-B19 IgM and IgG antibody by ELISA and HPV-B19 DNA by PCR. The plasmapheresis and administration of intravenous immunoglobulin showed the possible efficacy for her symptom throughout this clinical course. Moreover, bone marrow smear showed the finding of virus-associated hemophagocytic syndrome, and finally, she was died of cervical hemorrhage accompanied with disseminated intravascular coagulation syndrome on July 1996. HPV-B19 infection can present an atypical clinical picture that is highly suggestive of SLE. We suggest that the therapy of steroids and immuno-suppressive agents should be cautious, because these may potentially cause persistent chronic HPV-B19 infection and induced life-threatening clinical course.

We describe a 31-year-old Japanese female patient with systemic lupus erythematosus (SLE), who developed disseminated intravascular coagulation (DIC), fever, erythema on the hands, and aphthous stomatitis despite the absence of circulating anticoagulant. Since no other cause for DIC besides SLE could be demonstrated, she was treated with prednisolone and anticoagulants, which rapidly corrected the DIC as well as the other manifestations of SLE. During the episode of DIC, elevated serum anti-DNA antibody titers and decreased serum complement concentrations were not observed. In contrast, the serum concentration of soluble CD8 (sCD8) paralleled SLE disease activity. In addition, the concentration of plasma thrombomodulin was also increased. These observations suggest that the serum concentration of sCD8 is related to the clinical aspects of SLE, and that vasculitis might contribute to the development of SLE-associated DIC.

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.

Blood coagulation tests are useful to diagnose some thrombotic diseases. Particularly, these tests are valuable for the diagnosis of familiar thrombophilia, antiphospholipid antibody syndrome (APS) and disseminated intravascular coagulation (DIC). For the diagnosis of thrombophilia, determinations of both biological activity and antigen level of antithrombin III, protein C and protein S are important for initial screening. Since activated protein C (APC) resistance is extremely rare in Japanese, APC resistant test that based on APTT, is unnecessary to include as one of the screening tests. Detection of activity and antigen level of either plasminogen or fibrinogen is recommended to screen the plasminogen deficiency or dysfibrinogenemia. Determination of lupus anticoagulant is needed for the diagnosis of APS. At this time, the dilute phospholipid APTT (dAPTT) or the dilute Russell viper venom time (dRVVT) may be useful as a screening test for LA because procedure of these tests are basically simple to perform in Japanese laboratory. In the next step, cross mixing test of dAPTT (or APTT) should be perform to make a diagnose of LA more solid. Final confirm tests can be conveniently carried out with kit of either STACLOT or LA-CONFIRM. Platelet count and FDP (or FDP D dimer) assay are two essential tests for the diagnosis of DIC. Criteria of diagnosis for DIC recommended by Blood Coagulation Research Group of Japanese Ministry of Health and Welfare is not unnecessarily appropriate for practical use. TAT and PIC can be a good laboratory tests for early detection of hypercoagulable state in patients with DIC.

We analyzed the clinical and laboratory characteristics of 50 patients with catastrophic antiphospholipid syndrome (APS) (5 from our clinics and 45 from a MEDLINE computer-assisted review of the literature from 1992 through 1996). Thirty-three (66%) patients were female and 17 (34%) were male. Twenty-eight (56%) patients had primary APS, 15 (30%) had defined systemic lupus erythematosus (SLE), 6 (12%) had "lupus-like" syndrome, and 1 (2%) had rheumatoid arthritis. Mean age of patients in this series was 38 +/- 14 years (range, 11-74 yr). Three (6%) patients developed the clinical picture of catastrophic APS under the age of 15 years, and 11 (22%) were 50 years old or more. In 11 (22%) patients, precipitating factors contributed to the development of catastrophic APS (infections in 3, drugs in 3, minor surgical procedures in 3, anticoagulation withdrawal in 2, and hysterectomy in 1). The presentation of the acute multi-organ failure was usually complex, involving multiple organs simultaneously or in a very short period of time. The majority of patients manifested microangiopathy--that is, occlusive vascular disease affecting predominantly small vessels of organs, particularly kidney, lungs, brain, heart, and liver--with a minority of patients experiencing only large vessel occlusions. Thrombocytopenia was reported in 34 (68%) patients, hemolytic anemia in 13 (26%), disseminated intravascular coagulation in 14 (28%), and schistocytes in 7 (14%). The following antibodies were detected: lupus anticoagulant (94%), anticardiolipin antibodies (94%), anti-dsDNA (87% of patients with SLE), antinuclear antibodies (58%), anti-Ro/SS-A (8%), anti-RNP (8%), and anti-La/SS-B (2%). Anticoagulation was used in 70% of the patients, steroids in 70%, plasmapheresis in 40%, cyclophosphamide in 34%, intravenous gammaglobulins in 16%, and splenectomy in 4%. Most patients, however, received a combination of nonsurgical therapies. Death occurred in 25 of the 50 (50%) patients. In most, cardiac problems seemed to be the major cause of death. In several of these, respiratory failure was also present, usually due to acute respiratory distress syndrome and diffuse alveolar hemorrhage. Among the 20 patients who received the combination of anticoagulation, steroids, and plasmapheresis or intravenous gammaglobulins, recovery occurred in 14 (70%) patients. The use of ancrod and defibrotide appeared to be effective in the 2 respective patients in whom they were used.

A 22-year-old woman was admitted to our hospital with fever, generalized lymphadenopathy, and pancytopenia in February 1995. She was diagnosed as having systemic lupus erythematosus (SLE) based on positivity for anti-nuclear antibody, and polyarthritis among other findings. A diagnosis of disseminated intravascular coagulation (DIC) was made based on the increase of FDP and other data (DIC score: 7). We also detected an anti-fibrinogen antibody. Lymph node biopsy revealed subacute necrotizing inflammation and there were on signs of the hemophagocytic phenomenon in bone marrow. The DIC score improved and the anti-fibrinogen antibody disappeared in association with the response of SLE to prednisolone therapy. The onset of SLE associated with DIC has never been reported before, as far as we could determine. The mechanism of DIC associated with SLE may be related to endothelial damage caused by immune complexes.

A case of intestinal perforation associated with SLE is presented. A 54-year-old woman was diagnosed as having SLE twenty-five years ago when she had facial erythema, photosensitivity, oral aphtha, polyarthraliga, leukopenia, positive LE cell and positive antinuclear antibody. She had been treated with prednisolone and admitted to Kushiro City General Hospital because of one month history of fever and anorexia in February 1996. Laboratory findings did not reveal activity of SLE, and a diagnosis of urinary tract infection was made based on the findings of urinalysis. After severe diarrhea, disseminated intravascular coagulation (DIC) developed. A rectal perforation was revealed by endoscopic and radiological examination. An emergency laparotomy revealed necrosis of the rectum and sigmoidostomy was performed. The biopsied specimen of the rectum were diagnosed as gangrene of ischemic colitis histologically. Because of a penetration to the urinary bladder, an ureterocutaneostomy was performed. She died of sepsis and DIC on the 127th day of admission. Only 11 cases of intestinal perforation associated with SLE have been reported in Japan, and the association of vasculitis has been considered. In the present case, the prolonged use of prednisolone might cause the necrotizing ischemic colitis.
