Serum FDPs were investigated in 30 healthy and 95 patients with pulmonary thrombembolia, not-stabilized angina pectoris, myocardial infarction, rheumatism, rheumatoid arthritis, lupus erythematodes and dermatomyositis. FDPs are determined by hemagglutination inhibition according to Merskey. They are found in the sera of the healthy in average values of 3.73 mkgr/ml. The highest average values in the first 24 h were found in case of pulmonary thrombembolia up to 106.64 mkgr/ml, followed by rheumatoid arthritis 26.3 mkgr/ml, myocardial infarction with complication 22.4 mkgr/ml, rheumatism +5.58 mkgr/ml, not-stabilized angina pectoris 5.5 mkgr/ml; and noncomplicated myocardial infarction 4.3 mkgr/ml. By the third day of the disease FDP in pulmonary thrombembolia decreased, whereas a negligible elevation was observed in case of non-complicated myocardial infarction. The results were interpreted as well as the cause for the presence of the mentioned products in those groups of diseases. FDP determination is recommended as a routine method in case of: diagnosis of pulmonary thrombembolia, differentiation of myocardial infarction with or without complications, differentiation of pulmonary thrombembolia from myocardial infarction in emergency states, progressing with chest pain, collapse phenomena, dyspnea and establishment of the activity of the process of rheumatoid arthritis. FDP determination in stenocardia and rheumatism is not expedient.

In order to clarify the abnormalities of blood coagulation and fibrinolysis in patients with various renal diseases, some molecular markers for hemostasis and thrombosis were examined in comparison with those of the patients with disseminated intravascular coagulation. The results were as follows: 1) PIC was significantly higher in the patients with CGN, NS, SLE, HD and DIC than normal subjects. 2) TAT was significantly higher in the patients with CGN, NS, HD and DIC. 3) SFMC was significantly higher only in the patients of DIC. 4) FDP and FDP-E were significantly higher in the patients with HD and DIC. 5) D-dimer was significantly higher in the patients with CGN, CRF, HD and DIC. These results suggested that the abnormalities of blood coagulation and fibrinolysis in patients with various renal diseases are relatively mild, and situated between the normal subjects and patients with DIC.

Changes of blood coagulation in 32 cases of SLE were investigated. Abnormalities frequently found were elevation of blood fibrinogen, FDP, V111R: Ag levels, prolonged or shortened KPTT time, and depressed AT-III value. Half of the patients with SLE showed laboratory changes compatible with the diagnostic criteria of DIC, but acute DIC was encountered clinically only in 2 cases hypercoagulation state or hypercoagulation with lower fibrinolysis, however were frequently seen. Lupus anticoagulant were detected in 6 patients and deep vein thrombosis of lower extremity in 1 patient. Examination of blood coagulation in patients with SLE was, therefore, of clinical importance.

The intraglomerular location of coagulation-fibrinolysis factors (CFF) and a platelet membrane antigen (glycoprotein IIb-IIIa; GPIIb-IIIa) was determined in 101 patients with various glomerular diseases. Renal biopsy specimens were examined by immunofluorescence microscopy, using antisera against fibrinogen/fibrin reactive antigen (FRA), cross-linked fibrin degradation products (XL-FDP), fibronectin (FN), factor XIII-subunit a (F-XIIIa), plasminogen (Plg), alpha 2-plasmin inhibitor (alpha 2-PI) and GPIIb-IIIa. Intraglomerular deposits of the CFF were found at high rates in patients with IgA glomerulonephritis (GN), membranous nephropathy (MN) and lupus GN. The coexistence of deposits of these factors was ascertained by the double-staining method. The deposition rates of XL-FDP and GPIIb-IIIa were very low in patients with minimal-change nephrotic syndrome and focal glomerulosclerosis. Some cases of diabetic glomerulosclerosis (DGS) showed CFF deposition. FRA deposits associated with F-XIIIa and FN may indicate the presence of the cross-linked fibrin. Furthermore, the presence of Plg deposits together with alpha 2-PI and XL-FDP suggests the deposition of fibrin followed by fibrinolysis, but not of fibrinogen, and the coexistence of GPIIb-IIIa suggests the involvement of platelets in the reactions. These studies provide evidence that stabilized fibrin deposition with subsequent fibrinolysis and platelet activation take place in glomeruli in a fairly large proportion of patients with IgA GN, MN and lupus GN and in some cases of DGS.

To see whether or not the fibrin-stabilizing factor is involved in the pathogenesis of renal damage, we analyzed by IF the glomerular deposition of factor XIII (subunits A and S) in 161 patients with various renal diseases. In 4 out of 5 cases of thrombotic microangiopathy (80%), F XIII deposits were found in a continuous subendothelial pattern, in association with deposition of fibrinogen and FDP, suggesting the occurrence of intraglomerular coagulation. In 22 out of 45 patients with membranous GN (idiopathic or SLE-associated), F XIII deposits were found along the capillary walls in a subepithelial location. These findings were not correlated with the presence of particular histological or clinical features, nor with IF positive for fibrinogen, FDP and factor VIII, suggesting alternative pathways of fibrin formation or local collagen synthesis. Finally, in proliferative GN, either idiopathic (acute post-infectious and membranoproliferative) or systemic (SLE and vasculitis), as in other glomerular and non-glomerular diseases, the presence of F XIII deposits was negligible, even in cases positive for fibrinogen, FDP and factor VIII.

The concentration of urinary fibrin(ogen) degradation products (FDP) was determined by using enzyme immunoassay and radio immunoassay, and their urinary levels were compared with histologically classified types of glomerulonephritis. Urinary FDP levels were higher in the severe type of proliferative glomerulonephritis and at the active phase of systemic lupus erythematosus (SLE). They were also high in the membranous glomerulonephritis. Molecular weight of urinary FDP of a patient with severe proliferative glomerulonephritis was determined to be 150,000 and 68,000, respectively after gel filtration. Urinary FDP levels were higher in patients with glomerular fibrin deposit than in patients without fibrin deposit or normal volunteers. The amounts of excreted protein in urine was not related to the amounts of FDP. Decrease in the reciprocal of serum creatinine levels resulted in high urinary FDP levels, indicating that high urinary FDP levels may represent deterioration of renal function.

Activated protein C (APC)-protein C inhibitor (PCI) complex and APC-alpha 1antitrypsin (alpha 1AT) complex levels were measured in 29 patients positive for lupus anticoagulant (LA). LA was considered positive if two of the following three criteria were fulfilled: (1) prolongation of the activated partial thromboplastin time, (2) prolongation of the kaolin clotting time (KCT) and KCT mixing test, and (3) prolongation of the dilute Russell's viper venom time (DRVVT) and DRVVT/DRVVT with high lipid concentration. Plasma thrombin-antithrombin III (AT-III) complex and plasmin-alpha 2-antiplasmin inhibitor complex levels in patients positive for LA were increased slightly, but not significantly, and FDP-D-dimer and t-PA levels were not markedly increased. Plasma PAI-1 level in the LA-positive patients was significantly increased compared with normal volunteers. AT-III activity, protein C antigen, PCI antigen, and protein S antigen levels in the LA-positive patients were virtually normal, while protein C activity was slightly, but not significantly, decreased. APC-PCI complex level was increased in all LA-positive patients, and was not detectable in patients with systemic lupus erythematosus and normal volunteers. APC-alpha 1AT complex was increased slightly, in only two LA-positive patients; it was not detectable in the other patients or in the normal volunteers. These findings suggest that patients positive for LA are in a hypercoagulable state and that protein C activity in such patients is decreased, due to the activation of this protein.

A 26-year-old pregnant woman was diagnosed as having both lupus anticoagulant (LA) and anticardiolipin antibody (ACA). Her previous pregnancy ended in intrauterine fetal death at 27 weeks' gestation. During the present pregnancy she was treated with aspirin, dipiridamole, predonisolone, and heparin. At 24 weeks, fetal growth became retarded, accompanied by markedly decreased activities of AT-III, protein C, plasminogen and alpha 2-plasmin inhibitor. Supplement of human AT-III led both to prolongation of the gestational period and improvement of fetal growth. The pregnancy ended in cesarean section because of signs of fetal distress at 30 weeks. The infant was a 1025-g male with Apgar scores of 5 and 9 at one and five minutes, respectively, and is healthy. The mother developed DIC after surgery, but recovered after therapy. In this case, TAT, alpha 2PI-plasmin complex, FDP Ddimer, FPB beta 15-42, L-FDP showed little correlation with the clinical course.

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.

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.
