Fibrin sheath formation around long-term haemodialysis catheter is a common cause of failed dialysis access. Treatment options include pharmacological and mechanical methods. This paper reports a case of failed dialysis access due to fibrin sheath encasement. Pharmacologic thrombolysis, mechanical disruption using guide wire and catheter exchange had failed to address the issue. Eventually, fibrin sheath stripping using the loop snare technique was able to successfully restore the catheter function.

Lentinus edodes (shiitake mushroom) has exhibited fibrinolytic activity. We synthesized and characterized selenium nanoparticles (SeNPs) using protein precipitated from the mushroom. We also investigated the fibrinolytic activity of the SeNPs. The proteins from a crude extract of L. edodes were recovered through the use of aqueous 2-phase separation, and these we used as the capping agent in SeNP biosynthesis. We characterized the SeNPs using UV-visible spectrophotometry, field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), transmission electron microscopy (TEM), particle size distribution analysis, and Fourier transform infrared spectroscopy (FT-IR). The fibrinolytic capability of the SeNPs was tested through an in vitro fibrin plate assay. The UV-visible spectra showed maximal absorbance at 220 nm. FESEM images showed that the SeNPs were dispersed and did not clump. The TEM images revealed a spherical shape and average size of the SeNPs. The particle size distribution analysis confirmed the mean size of the SeNPs at 64.53 nm. A strong signal for the presence of selenium was observed in the EDX analysis. The FT-IR spectrum revealed the involvement of protein functional groups in the reduction of sel-enite. Overall, the SeNPs capped with protein from shiitake mushroom were effective as an in vitro fibrinolytic agent.

Fulltext Fibrinolytic activity and dose-dependent effect of incubating human blood clots in caffeic acid phenethyl ester: in vitro assays

Elnager A, Hassan R, Idris Z, Mustafa Z, Wan-Arfah N, Sulaiman SA, et al.

Biomed Res Int, 2015;2015:627471.

PMID: 25664321 DOI: 10.1155/2015/627471

Background. Caffeic acid phenethyl ester (CAPE) has been reported to possess time-dependent fibrinolytic activity by in vitro assay. This study is aimed at investigating fibrinolytic dose-dependent activity of CAPE using in vitro assays. Methods. Standardized human whole blood (WB) clots were incubated in either blank controls or different concentrations of CAPE (3.75, 7.50, 15.00, 22.50, and 30.00 mM). After 3 hours, D-dimer (DD) levels and WB clot weights were measured for each concentration. Thromboelastography (TEG) parameters were recorded following CAPE incubation, and fibrin morphology was examined under a confocal microscope. Results. Overall, mean DD (μg/mL) levels were significantly different across samples incubated with different CAPE concentrations, and the median pre- and postincubation WB clot weights (grams) were significantly decreased for each CAPE concentration. Fibrin removal was observed microscopically and indicated dose-dependent effects. Based on the TEG test, the Ly30 fibrinolytic parameter was significantly different between samples incubated with two different CAPE concentrations (15.0 and 22.50 mM). The 50% effective dose (ED50) of CAPE (based on DD) was 1.99 mg/mL. Conclusions. This study suggests that CAPE possesses fibrinolytic activity following in vitro incubation and that it has dose-dependent activities. Therefore, further investigation into CAPE as a potential alternative thrombolytic agent should be conducted.

Fulltext Pro-fibrinolytic potential of the third larval stage of Ascaris suum as a possible mechanism facilitating its migration through the host tissues

Diosdado A, Simón F, Morchón R, González-Miguel J

Parasit Vectors, 2020 Apr 20;13(1):203.

PMID: 32312291 DOI: 10.1186/s13071-020-04067-5

BACKGROUND: Ascaris roundworms are the parasitic nematodes responsible for causing human and porcine ascariasis. Whereas A. lumbricoides is the most common soil-transmitted helminth infecting humans in the world, A. suum causes important economic losses in the porcine industry. The latter has been proposed as a model for the study of A. lumbricoides since both species are closely related. The third larval stage of these parasites carries out an intriguing and complex hepatopulmonary route through the bloodstream of its hosts. This allows the interaction between larvae and the physiological mechanisms of the hosts circulatory system, such as the fibrinolytic system. Parasite migration has been widely linked to the activation of this system by pathogens that are able to bind plasminogen and enhance plasmin generation. Therefore, the aim of this study was to examine the interaction between the infective third larval stage of A. suum and the host fibrinolytic system as a model of the host-Ascaris spp. relationships.

METHODS: Infective larvae were obtained after incubating and hatching fertile eggs of A. suum in order to extract their cuticle and excretory/secretory antigens. The ability of both extracts to bind and activate plasminogen, as well as promote plasmin generation were assayed by ELISA and western blot. The location of plasminogen binding on the larval surface was revealed by immunofluorescence. The plasminogen-binding proteins from both antigenic extracts were revealed by two-dimensional electrophoresis and plasminogen-ligand blotting, and identified by mass spectrometry.

RESULTS: Cuticle and excretory/secretory antigens from infective larvae of A. suum were able to bind plasminogen and promote plasmin generation in the presence of plasminogen activators. Plasminogen binding was located on the larval surface. Twelve plasminogen-binding proteins were identified in both antigenic extracts.

CONCLUSIONS: To the best of our knowledge, the present results showed for the first time, the pro-fibrinolytic potential of infective larvae of Ascaris spp., which suggests a novel parasite survival mechanism by facilitating the migration through host tissues.

Disseminated Intravascular Coagulation (DIC) develops in patient with prostate cancer, which is manifested by systemic, intracranial, intracavitary or intracutaneous bleeding indicating uncompensated or excessive fibrinolysis (XFL). This case report is a description of a 61-year-old male with metastatic prostate cancer that progressed to manifest DIC. The condition is rare in clinical practice, and even rarer when is coupled with XFL. Treatment was mainly replenishing coagulation factors, platelets and controlling the disease progression with aggressive hormonal therapy. The patient progressed to coagulopathy further with fibrinolysis, hence leading to mortality. This case study discusses the pathophysiology of this complication and various methods to monitor the disease progression are discussed.

Int J Gynaecol Obstet, 1980 9 1;18(2):105-8.

PMID: 6108245 DOI: 10.1002/j.1879-3479.1980.tb00256.x

Coagulation, fibrinolytic activity and platelet function were studied in 104 Asian women volunteers who received 150 mg of depot medroxyprogesterone acetate intramuscularly every three months for two years or more. The results were compared with those in matched controls. There was a paucity of change in coagulation factors. The fibrinogen levels were increased and prothrombin time was shortened. The fibrinolytic activity, as shown by the euglobulin clot lysis time, was significantly increased. This latter change contrasts with the many reports concerning Caucasian women and may reflect an increase in fibrinolytic potential in Asian women.

Fulltext Comparable Enhanced Prothrombogenesis in Simple Central Obesity and Metabolic Syndrome

Mohd Nor NS, Saimin H, Rahman T, Abdul Razak S, Mohd Nasir N, Ismail Z, et al.

J Obes, 2018;2018:8508549.

PMID: 29785305 DOI: 10.1155/2018/8508549

Objective: There is limited data comparing prothrombogenic or fibrinolysis biomarkers (tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1)) simultaneously in subjects with Metabolic Syndrome (MS), simple central obesity without MS (COB) and normal controls (NC). We investigated the concentrations of fibrinolysis biomarkers in subjects with MS, COB and NC.

Methods: A cross-sectional study involving 503 drug naive subjects (163 males, aged 30-65 years old (mean age ± SD = 47.4 ± 8.3 years)) divided into MS, COB and NC groups. COB was defined as central obesity (waist circumference (WC) males ≥90 cm, females ≥80 cm) in the absence of MS according to the International Diabetes Federation 2006. Fasting blood levels of tPA and PAI-1were analyzed.

Results: MS and COB had significantly higher concentration of all biomarkers compared to NC. The MS group had significantly higher concentration of tPA and PAI-1 compared to COB. WC and HDL-c had significant correlation with all biomarkers (tPA p < 0.001, PAI-1 p < 0.001). Fasting plasma glucose and diastolic blood pressure were independent predictors after correcting for confounding factors.

Conclusion: Central obesity with or without MS both demonstrated enhanced prothrombogenesis. This suggests that simple obesity possibly increases the risk of coronary artery disease in part, via increased susceptibility to thrombogenesis.

Fibrinolytic response in women on low-dose oral contraceptive

Ishak R, Ahmad R, Gudum HR, Hassan K, Ang ES

Malays J Reprod Health, 1992 Jun;10(1):7-11.

PMID: 12345026

PIP: Long term use of low doses of combination oral contraceptives appears to increase plasminogen level, thereby increasing fibrinolytic activity and reducing the risk of thromboembolism. Blood levels of plasminogen, tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI), were measured before and after stress (5 minutes of stair climbing) in a group of 30 women, 23-40 years old, who had taken 30 mcg of ethinyl estradiol with 150 mcg of desogestrel or levonorgestrel for at least 1 year. Similar measurements were taken from a control group of 30 women matched for age, height, and weight. Plasminogen and tPA levels in both groups increased significantly after exercise. The level of PAI did not change significantly with stress in either group. The level of plasminogen was significantly higher in the group taking contraceptives, whether before or after exercise, when compared to the control group. Levels of tPA and PAI, although slightly increased in the oral contraceptive group, were not significantly different between the two groups. The increase in plasminogen may be due to the estrogen component of the contraceptives. Stress seems to increase fibrinolytic response.

PMID: 1084931

Five patients illustrate various aspects of obstetrical defibrination in West Malaysia, resulting from exaggeration of changes in fibrinolytic-coagulation equilibrium that occur at delivery. Hypofibrinogenaemia and fibrinolysis may occur in association or either feature predominate. These patients are from a population in which a variety of genetic and environmental factors may interact, e.g. abnormal haemoglobins, cold agglutinins, viral and other infections, introducing additional complications.

PMID: 3282374

Nephrotic syndrome is often associated with a hypercoagulable state and thrombotic complications. Thrombosis may be due to a number of abnormalities in blood, including AT III deficiency, increased concentrations of fibrinogen, factors V and VIII, and platelet hyperaggregability. The therapeutic approach to thrombosis in nephrotic syndrome is the use of anticoagulants as a preventive measure or an attempt at thrombolysis with streptokinase, urokinase, or stanozolol.

Allium sativum (garlic) is widely known and is consumed as a natural prophylactic worldwide. It produces more than 200 identified chemical compounds, with more than 20 different kinds of sulfide compounds. The sulfide compounds particularly are proven to contribute to its various biological roles and pharmacological properties such as antimicrobial, antithrombotic, hypoglycemic, antitumour, and hypolipidemic. Therefore, it is often referred as disease-preventive food. Sulphur-containing compounds from A. sativum are derivatives of S-alkenyl-l-cysteine sulfoxides, ajoene molecules, thiosulfinates, sulfides, and S-allylcysteine. This review presents an overview of the water-soluble and oil-soluble sulphur based phytochemical compounds present in garlic, highlighting their mechanism of action in treating various health conditions. However, its role as a therapeutic agent should be extensively studied as it depends on factors such as the effective dosage and the suitable method of preparation.
