AbstractBullous pemphigoid (BP), the most frequent blistering dermatosis in the elderly, is associated with increased mortality. The severity of BP can be assessed by detecting the anti-BP180 immunoglobulin G (IgG) concentration, but the lab test is not available in many community clinics. BP patients are usually in a hypercoagulable state with increased levels of D-dimer and fibrin degradation products (FDPs). We aimed to evaluate the use of D-dimer and FDPs in assessing BP severity. We compared the levels of plasma D-dimer, plasma FDPs, eosinophil counts, eosinophil cationic protein, and serum anti-BP180 IgG concentration between 48 typical BP patients and 33 Herpes zoster (HZ) patients (control group). Correlational analyses were conducted to determine the relationships between the lab values and common BP severity markers. The plasma D-dimer and FDP levels were higher in BP patients than in HZ controls (D-dimer: 3297 ± 2517 µg/L vs. 569.70 ± 412.40 µg/L; FDP: 9.74 ± 5.88 mg/L vs. 2.02 ± 1.69 mg/L, respectively, P < 0.0001). Significant positive correlations were found between D-dimer/FDP levels and BP severity markers (i.e. anti-BP180 IgG concentration [D-dimer: r = 0.3928, P = 0.0058; FDP: r = 0.4379, P = 0.0019] and eosinophil counts [D-dimer: r = 0.3625, P = 0.0013; FDP: r = 0.2880, P = 0.0472]) in BP patients. We also found an association between FDP and urticaria/erythema lesions (r = 0.3016, P = 0.0372), but no other BPDAI components. In 19 BP patients with complete remission after systemic glucocorticoid treatment, D-dimer and FDP levels decreased post-therapy (D-dimer: 5559 ± 7492 µg/L vs. 1738 ± 1478 µg/L; P < 0.0001; FDP: 11.20 ± 5.88 mg/L vs. 5.13 ± 3.44 mg/L; P = 0.0003), whereas they did not in BP patients with treatment resistant. Plasma D-dimer and FDP are convenient markers to evaluate BP severity assistant on BPDAI and eosinophil counts. FDP is also helpful for inflammatory lesions in BP patients.

Abstract Background Bullous pemphigoid (BP) is the most common blistering dermatosis with increasing mortality. Currently, the severity of BP can be assessed by the detection of anti-BP180 immunoglobulin G (IgG) titer, but it is absent in many grassroots clinics. BP patients are usually in a hypercoagulable state, and the levels of D-dimer and fibrin degradation products (FDPs) are elevated. Therefore, we aim to evaluate the use of D-dimer and FDPs in the assessment of BP severity. Methods This study included 33 BP and 33 Herpes zoster (HZ) patients, with the HZ patients serving as a control. The levels of plasma D-dimer and FDPs as along with eosinophil counts were recorded during a routine screening examination. Anti-BP180 IgG titer was tested by ELISA. BP lesion area was evaluated on admission. Correlational analyses were carried out between these indexes. Results The plasma D-dimer and FDP levels were higher in BP patients than in HZ patients. A significant positive correlation was found between the lesion area and both D-dimer and FDP levels in BP patients. There was also a positive association between anti-BP180 IgG and D-dimer, and between anti-BP180 IgG and FDP. Conclusions Plasma D-dimer and FDP may be convenient markers to evaluate the severity of BP.

OBJECTIVE: To assess the mean serum eosinophil cationic protein (s-ECP) concentrations among crop and dairy farmers and office controls, and further examine its relation to exposure duration, smoking habit, as well as presence or absence of asthma.METHODS: A cross-sectional survey was performed including examined group (EG), composed by agricultural workers (87 crop - EG1 and 83 dairy farmers - EG2), and control group (CG) composed by 80 office workers within the same enterprise.  We have used a questionnaire to record the chronic respiratory symptoms, detailed work history, specific farming activities and tasks performed and smoking history. Evaluation of examined subjects also included lung function tests, diagnosis of asthma, and measurement of s-ECP as a marker of inflammation.RESULTS: The main finding of the present study is that s-ECP concentrations were raised in subjects with asthma independent of the smoking habit. The mean s-ECP concentrations were higher in subjects of EG1 and EG2 compared with those in CG, but without reaching statistical significance. Mean s-ECP concentrations were significantly higher among subjects in EG1 exposed more than 20 years, while mean s-ECP concentrations were non-significantly higher in subjects of EG2 exposed more than 20 years, compared to those exposed less than 20 years. Mean s-ECP concentrations were higher among smokers within all three groups, but without reaching statistical significance between smokers and non-smokers. Mean s-ECP concentrations were significantly higher in subjects with asthma within EG1 (P = 0.049) and EG2 (P = 0.040), but also within those in CG (P = 0.046).CONCLUSION: Data obtained suggest that airway inflammation is present in farmers with asthma, and s-ECP is an important biomarker in means of reflecting disease severity and prognosis among exposed workers.

We have analysed the relationship of blood eosinophil count and serum eosinophil cationic protein (ECP) levels in patients with acute and chronic idiopathic urticaria. The ECP levels and eosinophil counts were measured in the peripheral blood of 15 patients with acute urticaria, 25 with chronic idiopathic urticaria and 10 normal healthy subjects. Blood eosinophil counts and serum ECP levels increased in all patients with acute urticaria. Concerning patients affected by chronic urticaria, taking into account the recrudescence of the disease at the moment of taking the blood sample, only symptomatic patients showed increased eosinophil blood values whereas serum ECP levels were increased both in symptomatic and asymptomatic patients. Furthermore, serum ECP levels in chronic urticaria did not correlate with the peripheral eosinophil counts, as they did in acute urticaria. The results of the present study indicate that eosinophils may play a role in the inflammatory mechanisms in patients with acute and chronic urticaria showing a positive correlation between serum ECP levels and disease activity.

Monoclonal antibodies (mabs) to crosslinked fibrin degradation products (XL-FDP) having the general formula D/Y[X]nY/D (known as X-oligomer) and D-D (known as D dimer) have been raised in balb/C mice by both a novel mtrasplenic and a conventional subcutaneous route of immunisation and by combinations of both these procedures. Mabs to X-oligomers (NIBn 52 and NIBn 123) obtained by an intrasplenic procedure have been demonstrated to crossreact only with X-oligomer in a 2-site ELISA procedure and not with D dimer or whole fibrinogen and have been shown to be of value m the examination of clinical material obtained from patients with various types of thrombosis and have also been useful in monitoring the efficacy of thrombolytic therapy. The X-oligomer mabs are immunoglobulins of the M class. It was demonstrated that their unique specificity for conformational epitopes on the large X-oligomer fragments does not reside in the IgM structure since alterative immunisation procedures have been used to generate mabs of the IgG class which have the same specificity. Using immunoglobulin class switching in culture rather than during immunisation was suggested by certain cell lines which produced both IgM and IgG specific for X-oligomer. This latter point needs rigorous validation.Immunoglobulin G type mabs to highly purified D dimer were raised by conventional subcutaneous immunisation of balb/C mice. One of these, NIBn-11, was found to crossreact with PVC-immobilised X-oligomer and D dimer but not with fibrinogen. However NIBn-11 did not bind to D dimer in a 2-site ELISA procedure while crossreactmg quite avidly with X-oligomer. This suggests that the D dimer epitope to which NIBn-11 is directed is expressed in some conformations and not m others and that these conformations are always expressed in the complex X-oligomer group of fragments. These mabs, whilst of value in measuring certain unique fibrin fragments m plasma, are useful in the epitope mapping of fibrinogen/fibrin and their plasmm-mediated

Introduction Although D-dimer is a useful biomarker of thrombosis, there are many D-dimer kits, with high and low fibrinogen and fibrin degradation products (FDP)/ D-dimer ratios. Methods Plasma D-dimer levels were measured using three different kits in critically ill patients to examine the usefulness of such measurements for detecting the thrombotic diseases and determining the correlation with the FDP and FDP/D-dimer ratio. Results Although three D-dimer kits showed marked utility for diagnosing disseminated intravascular coagulation (DIC) and peripheral arterial and venous thromboembolism (PAVTE), the D-dimer levels determined using the three kits varied among diseases. Indeed, one D-dimer kit showed a high FDP/D-dimer ratio, and another kit showed a low FDP/D-dimer ratio. D-dimer kit with low FDP/D-dimer ratio tended to have high cut-off values and low specificity for diagnosing DIC and PAVTE. In D-dimer kit with high FDP/D-dimer ratio, FDP/D-dimer ratios in patients with thrombosis was significantly higher than that in patients without thrombosis. Conclusion All three D-dimer kits show utility for detecting thrombotic diseases. However, the D-dimer levels determined using the kits varied due to differences in the FDP/D-dimer ratio. In combination with the FDP level, a D-dimer kit with a high FDP/D-dimer ratio may be useful.

Plasma levels of crosslinked fibrin degradation products (XLDP) were measured before and at the end of the administration of rt-PA (40 to 100 mg over 1.5 to 8 hours) in healthy volunteers (n=5) and patients with deep venous thrombosis (DVT) (n=8), pulmonary embolism (PE) (n=16)and myocardial infarction(MI)(n=10). Determinations were performed using our newly developed ELISA, specific for crosslinked fibrin derivatives, based on two monoclonal antibodies (15C5 and 8D3H2) raised against purified human fragment D-dimer. All plasma samples were collected on citrate and trasylol. Results are expressed as mean and range of D-dimer equivalents (μg/ml).Baseline levels in patients with MI are only slightly elevated. The increased levels inDVT and PE are in agreement with previous studies. After infusion of rt-PA a small increase of XLDP is seen even innormal subjects. A very marked increasof XLDP is detected in patients with PE and DVT but not in patients with MI. This may reflect differences in the amounts of fibrin clot dissolved in these patient groups.No significant correlation was found between the increase of XLDP and success of therapy, although a significant difference in D-dimer levels was formed between the two groups with PE: successful (n=ll): 116 (range 61-192) vs. unsuccessful (n=5): 68 (36-155).Thus, XLDP are already elevated under baseline conditions in patients with DVT and PE and increase very markedly during thrombolytic therapy. The absolute levels after thrombolytic therapy do not strictly correlate with success of therapy. It could be useful to measure D-dimer levels during early stages of therapy, because the rate of increase of XLDP levels might correlate with the efficacy of thrombolytic treatment.

Abstract Background Platelet dysfunction often accompanies trauma-induced coagulopathy. Because soluble fibrin impairs platelet glycoprotein VI (GPVI) signaling and platelets of trauma patients can display impaired calcium mobilization, we explored the role of fibrinolysis on platelet dysfunction during trauma. Methods Convulxin-induced GPVI calcium mobilization was investigated in healthy platelet-rich plasma (PRP) pretreated with thrombin and tissue plasminogen activator (tPA). Blood samples from healthy participants (n = 7) and trauma patients (n = 22) were tested for platelet calcium mobilization, plasma D-dimer, platelet D-dimer binding (via flow cytometry), and platelet lumi-aggregometry. Results For healthy platelets, maximal platelet dysfunction was observed when cross-linked soluble fibrin (no tPA) or cross-linked fibrin degradation products (FDPs) were generated in suspension before convulxin stimulation. Lack of fibrin polymerization (inhibited by Gly-Pro-Arg-Pro [GPRP]) or lack of factor XIIIa cross-linking (T101-inhibited) restored GPVI signaling, whereas non–cross-linked FDPs only partially blocked signaling induced by convulxin. In addition, D-dimer added to healthy PRP impaired platelet aggregation and dense granule release induced by various agonists. Plasma D-dimer level was strongly correlated (R = 0.8236) with platelet dysfunction as measured by platelet calcium mobilization induced with various agonists. By 48 to 120 h after trauma, plasma D-dimer levels declined, and platelet function increased significantly but not to healthy levels. Trauma platelets displayed elevated D-dimer binding that was only partially reduced by αIIbβ3-inhibitor GR144053. After 60-minute incubation, washed healthy platelets resuspended in plasma from trauma patients captured approximately 10 000 D-dimer equivalents per platelet. Conclusions During trauma, D-dimer and FDPs inhibit platelets, potentially via GPVI and integrin αIIbβ3 engagement, contributing to a fibrinolysis-dependent platelet loss-of-function phenotype.
