Changes in the blood coagulation profile after ovariohysterectomy in female dogs This study investigated changes in the coagulation profile of 10 healthy female dogs subjected to ovariohysterectomy. Blood samples were collected three times - before, directly after and 24 h after surgery. Plasma samples were analyzed to determine thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen content, D-dimer content and antithrombin (AT) III activity. The results revealed post-operative haemostatic system disorders related to prolonged APTT, higher fibrinogen and D-dimer concentrations and lower levels of AT III activity.

Abstract The purpose of this study was to investigate possible alterations in acid-base balance parameters and the coagulation profile in neonatal diarrheic calves. Twenty neonatal diarrheic and 20 clinically healthy neonatal calves aged between 1 week to 10 days were used. All blood samples were taken on the third day from the onset of diarrhea symptom. Venous blood samples were collected from each animal to determine platelet numbers, pH, pCO2, pO2, HCO3-, BE, O2SAT, ctCO2 and electrolytes (K+, Na+ and Cl-). Plasma samples were collected from each animal for the measurement of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), the concentrations of fibrinogen, D-dimer and the activity of antithrombin III (AT III). Blood pH (7.19), BE (-10.6 mmol/l), HCO3 - (25.15 mmol/l), pO2 (3.33 kPa), O2SAT (24.12 %) were significantly lower and serum concentration of K+ (6.55 mmol/l) was significantly higher in diarrheic calves. These changes indicate the state of uncompensated metabolic acidosis with accompanying hyperkalemia. TT (32.05s) and APTT (39.9s) values were more prolonged in calves with diarrhea than in the control group. D-dimer (587.25 μg/l) concentrations were significantly increased while a visible drop in AT III (103.75%) activity and platelets counts (598 x109/l) were observed in diarrheic group of calves. The results suggest that a consumptive type of disseminated intravascular coagulation (DIC) developed in diarrheic calves.

Abstract Twenty bitches with acute endometritis-pyometra complex (EPC) and 20 clinically healthy bitches were examined. The following coagulation parameters were determined in haemostatic evaluations: prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), fibrinogen concentrations (FBG), D-dimer concentrations (D-D), antithrombin activity (AT), and blood platelet counts (PLT). Morphological and biochemical blood parameters were also analysed. Examinations of animals affected by EPC revealed blood coagulation and fibrinolytic disorders, and the noted results (PT 13.7 ±1.06 s, aPTT 23.4 ±1.04 s, TT 15.6 ±0.68 s, FBG 2.2 g/L, D-D 785.4 ±103.05 μg/L, AT 111.1 ±13.51%, PLT 169.30 ±126.31 103/μL) point to a high risk of disseminated intravascular coagulation. The findings indicate that the coagulation parameters of bitches affected by EPC should be analysed before treatment as the noted disorder can significantly complicate therapy and ovariohysterectomy, and endanger the patients' life.

Bleeding time in rats was markedly prolonged after the adminstration of the water extract of Hsien-Ho-T'sao. This antihemostatic effect was more marked in the group of i.p. injection of the drug than in the group of p.o. administration for 2 to 7 consecutive days. Blood coagulation studies showed that plasma prothrombin time, activated partial thromboplastin time and stypven time were prolonged, while thrombin time adnd fibrinogen level were not changed. The thromboelastographic recording showed that reation time was prolonged and maximal elasticity of clot was decreased. In addition, ADP- and collagen- induced aggregations of platelet-rich plasma was suppressed. In conclusion, the prolongation of the bleeding time might be due to both anticoagulant and antiplatelet action of the drug.

The comorbid course of liver cirrhosis and atrial fibrillation causes higher levels of hospitalizations, mortality and ischemic stroke. According to current data, hemostasis in patients with liver cirrhosis is in a rebalanced dynamic state, but there are no data on the effect of atrial fibrillation on the hemostasis in patients with liver cirrhosis. Aims of the study. To assess abnormalities in primary, secondary haemostasis and fibrinolytic system in patients with liver cirrhosis and atrial fibrillation by using standard laboratory coagulation parameters and to investigate their changes depending on the stage of liver cirrhosis A, B, C according to Child-Pugh score. Materials and methods. A cross-sectional prospective study was conducted with the inclusion of 106 patients aged 42 to 83 years: group I (n = 70) - with liver cirrhosis and atrial fibrillation, II (n = 36) - with liver cirrhosis, which were distributed depending on the Child-Pugh score stages of cirrhosis and 20 healthy individuals. The levels of platelets, activated partial thromboplastin time, international normalized ratio, prothrombin time, thrombin time, fibrinogen, D-dimer were assessed on a Steellex M200 coagulometer. Statistical analysis (IBM SPSS Statistics) was performed. Results. The level of platelets in patients of group I was reduced by 37.4% (200 ± 8.33 vs. 274.7 ± 3.4; p,000.001), an activated partial thromboplastin time was prolonged by 38.6% (44.35 ± 1.39 vs. 32.01 ± 0.63, p˂0.001), prothrombin time was prolonged by 73.5% (19.4 ± 0.87 vs. 11.18 ± 0.53, p˂0.001), thrombin time was prolonged by 2.07 (25, 7 ± 1.31 vs. 12.4 ± 0.66, p˂0.001), the international normalized ratio was increased by 24.3% (1.38 ± 0.04 vs.1.11 ± 0.01, p˂0.001) compared to control. The fibrinogen level was 20.9% higher (4.17 ± 0.17 vs. 3.45 ± 0.11, p˂0.001) than in control group and was 83.7% higher (4.17 ± 0.17 vs. 2.27 ± 0.13, p˂0.001) than in group II. The D-dimer level was 83% higher than in control (675 ± 22.3 vs. 368.8 ± 21.85, p˂0.001) and 44% higher (675 ± 22.3 vs. 469 ± 37.18, p ˂0.001) compared with group II. Conclusions. In patients with liver cirrhosis and atrial fibrillation abnormalities of primary hemostasis are detected due to decrease of platelets on the background of portal hypertension. At the secondary stage of hemostasis indicators of external and internal coagulation mechanisms are prolonged due to the reduced synthesis of coagulation factors by the liver. Increased level of fibrinogen is determined at the stage of compensated and subcompensated cirrhosis with a gradual decrease at the stage of decompensation. The high activity of the fibrinolytic system is observed due to increase in the D-dimer levels, which may indicate a prothrombotic state in these patients.

Coagulatory abnormalities are common in renal dysfunction in humans. The studies on coagulatory abnormalities in renal failure in dogs are limited. The present paper deals with coagulation profile in acute and chronic kidney disease in dogs. The haemostatic defects observed in acute renal dysfunction included thrombocytopaenia, prolonged capillary bleeding time (CBT), elevated D-Dimer and hypoantithrombinemia which indicated a hypercoagulable state. Prolongation of prothrombin time (PT), activated partial thromboplastin time (aPTT), elevated D-Dimer concentration and hypoantithrombinemia in chronic kidney disease indicated the presence of hypocoagulable state

Introduction. Currently there is little information on the effects of prolactin (PRL) on the coagulation and fibrinolytic systems. Objective. The aim of this study was to evaluate the effects of hypeprolactinemia on the parameters of the hemostatic system and activation of the coagulation system. Methods. We studied PRL levels, body mass index (BMI), values of activated partial thromboplastin time (aPTT), prothrombin time (PT), thrombin time (TT), D-dimer level, von Willebrand factor antigen (vWFAg) and fibrinogen in 15 young female patients with microprolactinomas before and after therapy and in 15 healthy female controls. Results. As expected, pretreatment PRL levels were significantly higher in patients than in controls (140.90?42.87 vs. 12.53?4.05 ng/ml; p<0.001). PT, although still in the normal range, was prolonged in patients with hyperprolactinemia as compared to the control group (13.53?1.39 vs. 12.65?0.53 s; p=0.03) and normalized after therapy (12.69?0.65 vs. 12.65?0.53 s; p=0.88). TT, although in normal range, was significantly shorter in the hypeprolactinemic patients than in the controls (14.34?4.52 vs. 17.21?1.35 s; p<0.025) and after treatment remained significantly shorter than in the controls (15.17?1.55 vs. 17.21?1.35 s; p<0.0001). D-dimer values before treatment in the patients with hyperproplactinemia were above the normal range (239.47?107.93 vs. 131.27?50.64 ng/ml, p=0.002) and decreased to normal values after therapy (239.47?107.93 vs. 146.60?39.15 ng/ml; p<0.001). D-dimer levels correlated with PRL (r=0.30) and the change in serum D-dimer values significantly correlated with the change in PRL levels during therapy (r=0.62). aPTT, vWFAg and fibrinogen were similar in patients and controls. Conclusion. In our study, increased thrombin generation that resulted in elevated D-dimer levels may be one of the contributing factors to the prethrombotic state in patients with hyperprolactinemia.

SummaryA study conducted in rats exposed to a continuous noise of 110 decibels over a period of 3 weeks revealed development of significantly prolonged bleeding time, higher plasma fibrinogen content, and progressively shorter activated partial thromboplastin time in test animals. These changes suggest a coagulopathy induced by noise stress.

AbstractBackgroundAs the number of patients increases, there is a growing understanding of the form of pneumonia sustained by the 2019 novel coronavirus (SARS-CoV-2), which has caused an outbreak in China. Up to now, clinical features and treatment of patients infected with SARS-CoV-2 have been reported in detail. However, the relationship between SARS-CoV-2 and coagulation has been scarcely addressed. Our aim is to investigate the blood coagulation function of patients with SARS-CoV-2 infection.MethodsIn our study, 94 patients with confirmed SARS-CoV-2 infection were admitted in Renmin Hospital of Wuhan University. We prospectively collect blood coagulation data in these patients and in 40 healthy controls during the same period.ResultsAntithrombin values in patients were lower than that in the control group (p < 0.001). The values of D-dimer, fibrin/fibrinogen degradation products (FDP), and fibrinogen (FIB) in all SARS-CoV-2 cases were substantially higher than those in healthy controls. Moreover, D-dimer and FDP values in patients with severe SARS-CoV-2 infection were higher than those in patients with milder forms. Compared with healthy controls, prothrombin time activity (PT-act) was lower in SARS-CoV-2 patients. Thrombin time in critical SARS-CoV-2 patients was also shorter than that in controls.ConclusionsThe coagulation function in patients with SARS-CoV-2 is significantly deranged compared with healthy people, but monitoring D-dimer and FDP values may be helpful for the early identification of severe cases.

Abstract Abstract 5248 In India trauma related deaths occur every 1.9 minutes. Mortality in severe traumatic injury (ISS>16) is six times higher in developing country like India. Coagulopathy is observed in almost 25– 30% of trauma patients which itself is an independent risk factor for haemorrhage. Coagulopathy detected early after injury is indicative of injury severity and itself is a prognostic factor for mortality. Aim To find out the usefulness of thromboelastography (TEG) in detecting coagulopathy in contrast to conventional methods of plasma based standard coagulation parameters (PT, aPTT, TT, fibrinogen, D-dimer) Objective To detect coagulopathy early by TEG in trauma patients within 24 hrs after injury which can be useful to guide haemostatic therapies to reduce mortality. Materials and methods Patients admitted to trauma casualty were studied within 24 hrs after injury. Native whole blood was withdrawn through venepuncture appropriately in syringe using 21G needle and TEG was performed within 2 mins. Blood was also collected in citrated tube to assess standard coagulation parameters (prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen, D-dimer) and also by means of thromboelastography. Results Patients (n=87,New ISS-24.78(mean)) admitted to J.P.N Apex trauma centre casualty from 1st April,2011 to 31st July,2011 were studied. The cases included in the study were isolated head injury (n=40, NISS-25.87(mean)), multiple trauma with head injury (n=13,NISS – 30.69 (mean)) and trauma other than head injury (n=34, NISS-21.24 (mean)).Thromboelastography was performed using whole blood (n=69) and citrated blood (n=18). Coagulation tests were performed on all 87 patients using both TEG and conventional coagulation parameters. Total 52 patients showed coagulopathy by TEG and only 14 patients showed coagulopathy by standard coagulation parameters (prothrombin time, activated partial thromboplastin time). Only in 10 cases coagulopathy was detected by both methods. 4 patients showed coagulopathy only by conventional methods while 42 patients showed coagulopathy by only Thromboelastography (TEG). To find out whether there is any stastistical significance in the observed apparently better result by TEG, McNemar Test was carried out and P value was <0.0001. Conclusion Thromboelastography could be a better technique as compared to conventional measurements of PT, aPTT, TT, Fibrinogen, D-dimer in early detection of coagulopathy in trauma patients.

The comparative effects of glycosaminoglycans and acetaldehyde (AcH) – glycosaminoglycan (GAG) mixtures upon Factor Xa- (FXa) and Factor X-deficient plasma (FXDP) have been studied by activated partial thromboplastin time (APTT) studies. Heparin at 0.025, 0.030, 0.04, and 0.05 U statistically prolonged the APTT when pre-incubated with FXa at 37°C for 3 min prior to addition to FXDP and subsequent addition of Ca2+. Upon addition of 0.25, 0.375, and 0.5 µg heparin-6000 (H6k) to FXa, significant increases in APTT were observed. Similarly, profound increases in APTT were observed when 0.5, 0.75, and 1.0 µg heparin-3000 (H3k) was added to FXa. The chondroitin sulfates (CSA, CSB, CSC) had far less impact upon APTT with the FXa–FXDP system. In examining the effects of AcH–GAG mixtures upon the clotting factor, it was observed that 44.3 and 443 mM AcH synergistically prolonged the APTT in a statistically significant manner regardless of the order of premixing the three components. Hence, AcH may play a role in prolonging APTT in alcoholics. It synergistically prolonged APTT in concert with GAGs and FXa at the AcH levels used in this study. The effect of the GAGs upon FXDP is far less than its effect upon FXa.Key words: Factor Xa, acetaldehyde, heparin, glycosaminoglycans, blood coagulation.
