Abstract
Cardiovascular disorders, including acute myocardial infarction (AMI), often lead to blood clot formation, impacting blood circulation. Streptokinase, a cost-effective and widely available thrombolytic agent, is crucial in treating thrombosis. This study aimed to produce streptokinase from Streptococcus pyogenes EBL-48 and compare its efficacy with heparin in an animal model. We evaluated the clot-lysing effectiveness of streptokinase produced from Streptococcus pyogenes EBL-48, emphasizing its low cost and ease of production. Streptokinase was produced using pre-optimized fermentation media and purified through ion exchange and gel-filtration chromatography. In vivo analysis involved inducing clots in a trial animal model using ferric chloride, comparing streptokinase with heparin. Ultrasonography assessed the clot-lysing activity of streptokinase. Streptokinase (47 kDa) effectively lysed clots, proving its low cost, easy production, and minimal adverse effects. Ultrasonography confirmed its fibrinolytic efficacy. These findings highlight potential as an affordable and easily produced thrombolytic agent, particularly relevant in resource-limited settings. Streptokinase efficacy and minimal adverse effects make it a promising option for thrombolytic therapy, especially in economically constrained regions. Future studies could optimize production techniques, explore different strains, and conduct clinical trials for human validation. Comparative studies with other thrombolytic agents would enhance understanding of their advantages and limitations.

Abstract
Previously, the direct interactions of Bβ26-42 fibrin residues with prothrombin were demonstrated. It was also shown that forming prothrombin complexes with E- or DDE-fragments causes non-enzymatic prothrombin activation. The direct measuring of the prothrombin level in the blood plasma of patients with acute myocardial infarction (AMI) allowed us to find a situation where such an activation can occur in vivo. Blood coagulation parameters in the blood plasma of patients with AMI were measured at 2 hours, three days, and seven days after the thrombolysis by streptokinase accompanied with intravenous administration of anticoagulants: unfractionated high molecular weight heparin (HMWH) and low-molecular-weight heparin (LMWH). The prothrombin level in the blood plasma of patients with AMI was normal before thrombolytic therapy and substantially decreased after streptokinase administration. This effect was prominent in the case of concomitant anticoagulant therapy with LMWH and was not observed when HMWH was applied. It can be explained by the fact that LMWH preferentially inhibits factor Xa, while the HMWH is an effective inhibitor of both factor Xa and thrombin. This observation suggested that the prothrombin level decrease was caused by the thrombin-like activity and possible autolysis of prothrombin by thrombin. Also, thrombolytic therapy with streptokinase caused the accumulation of fibrin degradation products (FDPs), some of which were able to bind prothrombin. The dramatic decrease of prothrombin level in the blood plasma of patients with AMI during thrombolysis allowed us to conclude the non-enzymatic prothrombin activation with the following autolysis of prothrombin that contributes to the pathology.

Abstract
Acute thrombosis has a narrow therapeutic window and remains the leading cause of morbidity and mortality, while thrombolytic therapy has limited efficacy and risk of side effects. We have developed and investigated new fibrin-specific systems for local drug delivery to increase efficiency while minimizing the side effects of streptokinase. The experiment was carried out on dogs with 2-h thrombi in the femoral artery received intravenous injections of streptokinase, liposome-bound and free streptokinase at 40/60% ratio, and immunoliposomes. The completeness of the vessel lumen restoration affected by the thrombus, and the risks of side effects were assessed. Fibrinolytic parameters (plasminogen, fibrinogen, alpha2-antiplasmin, and D-dimers levels) were measured at several time points after thrombus induction and the administration of the drug. There was a strong activation of fibrinolysis and consumption of fibrinolysis inhibitors after therapy with all liposomal forms of streptokinase. According to the ultrasound data, immunoliposomal form of streptokinase significantly reduces the degree of residual stenosis to 32% [30.5; 33.7] in 180 min after injection. The high fibrinolytic effect of liposomal forms of streptokinase is not accompanied by a sharp drop in the fibrinogen concentration in the blood compared to the native streptokinase by 60 min. The morphometric evaluation of the artery samples showed that immunoliposomal form of streptokinase induces a significant increase in the degree of free vascular lumen compared to the native streptokinase (71.3% (62.7; 77.5) vs. 47.7% (39.6; 55.7), p < 0.001). Thus, the study shows the efficacy of streptokinase-induced thrombolysis using immunoliposomal form of drug delivery system. Mechanism of action of the immunoliposomal delivery system.

Abstract
Among children, neonates have the highest incidence of thrombosis. Thrombolytic agents are used for the management of life and/or organ-threatening thrombosis. Literature on the efficacy and safety of thrombolytic agents in neonates is limited. We reviewed the evidence on dosing, administration, monitoring and treatment duration of tissue plasminogen activator (tPA), streptokinase and urokinase (URK) in neonates (≤ 28days). A systematic literature search was conducted of current databases from inception until 31 March 2021. The initial search yielded 6881 articles and 18 were retained for review. tPA, streptokinase and URK was utilized in 12, seven and four studies on 115, 51 and 16 patients, respectively. The dose range for tPA, streptokinase and URK was 0.01 -0.6 mg/kg/h, 50-2000 and 1000-0 000 units/kg/h, respectively, and treatment duration ranged from 30 min to 30 days. This is the first study to objectively summarize the efficacy and safety of thrombolytic agents in neonates. Overall, thrombolysis was associated with 87.9% complete or partial thrombus resolution and 7.4% recurrence risk. The bleeding risk associated with thrombolytic agents was 23.1% on pooled analysis, which is higher than other anticoagulants. Larger prospective studies are required to determine effective dosing regimens of these therapeutic drugs and further clarify their efficacy and safety.

Abstract
Background Fibrinolysis using streptokinase or tenecteplase remains the primary reperfusion strategy for ST-elevation myocardial infarction (STEMI) in many Asian countries, including Malaysia. Comparative outcomes of these two fibrinolytic agents in the Asian population were inconclusive despite being widely used. Aim We aimed to assess and compare the outcomes of streptokinase versus tenecteplase in STEMI reperfusion of an Asian population. Method This single-centre retrospective study analysed data on STEMI patients who received fibrinolytic therapy from 2016 to 2020 in the Emergency Department of the largest tertiary hospital in Malaysia. Total population sampling was used in this study. Based on the propensity score matching, 359 patients receiving streptokinase were matched against 359 patients receiving tenecteplase by incorporating 16 variables that potentially affect mortality. 30-day mortality, stroke and major bleeding were the primary outcome measures. Results There was no significant difference in 30-day mortality between streptokinase (n = 39, 11.2%) and tenecteplase (n = 46, 13.2%) groups (p = 0.418). The rates of ischemic strokes [streptokinase (n = 1, 0.3%) versus tenecteplase (n = 3, 0.9%), p = 0.624], intracranial haemorrhage [streptokinase (n = 3, 0.9%) versus tenecteplase (n = 1, 0.3%), p = 0.624] and major bleeding [streptokinase (n = 4, 1.1%) versus tenecteplase (n = 3, 0.9%), p = 0.624], were comparable for the two groups. The incidences of failed thrombolysis were significantly higher in the tenecteplase arm. Hypotension and allergic reaction were significantly higher in the streptokinase arm. Conclusion Streptokinase and tenecteplase are fibrinolytic agents with similar efficacy and safety in STEMI reperfusion therapy in our Asian population.

Abstract
Atherosclerosis is the pathognomic sign of ischaemic heart disease. Inflammation of the coronary artery contributes to the development of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict the risk of CAD and associated events in patients with ST-Segment elevation myocardial infarction (STEMI). This study was done to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in predicting in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase (STK). This cross sectional descriptive type of study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August, 2017 to October, 2018. The STEMI patients, thrombolysed with STK had blood samples at admission, analyzed for complete blood counts and NLR calculated. They were grouped into two, low and high NLR, taking 4.50 as cut-off value. Chi square test was used to compare rate of adverse events and death in hospital stay. Logistic regression analysis was used to estimate predictive ability of NLR for in-hospital cardiac events. A total of 87 (39.90%) patients had complications. Patients in high NLR group had higher rate of complications (48.3% vs. 22.5%, p<0.001) in hospital than those in low NLR group. Arrhythmias (21.1% vs. 9.9%, p<0.041), heart failure (27.9% vs. 14.1%, p=0.024), cardiogenic shock (16.3% vs. 4.2%, p<0.011), death (6.8% vs. 2.8%, p=0.227), re-infarction /post MI angina (4.1% vs. 0.0% p=0.084) occurred more in high NLR group. Mean NLR was significantly different between Group I and Group II (3.11±0.84 vs. 10.20±6.08, p<0.0001). Multivariate regression analysis showed NLR an independent predictor of in-hospital adverse cardiac events (p<0.0001). High on admission NLR is an independent predictor for in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase.

Abstract
BACKGROUND Pleural infection, including parapneumonic effusions and thoracic empyema, may complicate lower respiratory tract infections. Standard treatment of these collections in adults involves antibiotic therapy, effective drainage of infected fluid and surgical intervention if conservative management fails. Intrapleural fibrinolytic agents such as streptokinase and alteplase have been hypothesised to improve fluid drainage in complicated parapneumonic effusions and empyema and therefore improve treatment outcomes and prevent the need for thoracic surgical intervention. Intrapleural fibrinolytic agents have been used in combination with DNase, but this is beyond the scope of this review. OBJECTIVES To assess the benefits and harms of adding intrapleural fibrinolytic therapy to standard conservative therapy (intercostal catheter drainage and antibiotic therapy) in the treatment of complicated parapneumonic effusions and empyema. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and Embase, ClinicalTrials.gov and the World Health Organization (WHO) trials portal. We contacted trial authors for further information and requested details regarding the possibility of unpublished trials. The most recent search was conducted on 28 August 2019. SELECTION CRITERIA Parallel-group randomised controlled trials (RCTs) in adult patients with post-pneumonic empyema or complicated parapneumonic effusions (excluding tuberculous effusions) who had not had prior surgical intervention or trauma comparing an intrapleural fibrinolytic agent (streptokinase, alteplase or urokinase) versus placebo or a comparison of two fibrinolytic agents. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data. We contacted study authors for further information. We used odds ratios (OR) for dichotomous data and reported 95% confidence intervals (CIs). We used Cochrane's standard methodological procedures of meta-analysis. We applied the GRADE approach to summarise results and to assess the overall certainty of evidence. MAIN RESULTS We included in this review a total of 12 RCTs. Ten studies assessed fibrinolytic agents versus placebo (993 participants); one study compared streptokinase with urokinase (50 participants); and one compared alteplase versus urokinase (99 participants). The primary outcomes were death, requirement for surgical intervention, overall treatment failure and serious adverse effects. All studies were in the inpatient setting. Outcomes were measured at varying time points from hospital discharge to three months. Seven trials were at low or unclear risk of bias and two at high risk of bias due to inadequate randomisation and inappropriate study design respectively. We found no evidence of difference in overall mortality with fibrinolytic versus placebo (OR 1.16, 95% CI 0.71 to 1.91; 8 studies, 867 participants; I² = 0%; moderate certainty of evidence). We found evidence of a reduction in surgical intervention with fibrinolysis in the same studies (OR 0.37, 95% CI 0.21 to 0.68; 8 studies, 897 participants; I² = 51%; low certainty of evidence); and overall treatment failure (OR 0.16, 95% CI 0.05 to 0.58; 7 studies, 769 participants; I² = 88%; very low certainty of evidence, with evidence of significant heterogeneity). We found no clear evidence of an increase in adverse effects with intrapleural fibrinolysis, although this cannot be excluded (OR 1.28, 95% CI 0.36 to 4.57; low certainty of evidence). In a sensitivity analysis, the reduction in referrals for surgery and overall treatment failure with fibrinolysis disappeared when the analysis was confined to studies at low or unclear risk of bias. In a moderate-risk population (baseline 14% risk of death, 20% risk of surgery, 27% risk of treatment failure), intra-pleural fibrinolysis leads to 19 more deaths (36 fewer to 59 more), 115 fewer surgical interventions (150 fewer to 55 fewer) and 214 fewer overall treatment failures (252 fewer to 93 fewer) per 1000 people. A single study of streptokinase versus urokinase found no clear difference between the treatments for requirement for surgery (OR 1.00, 95% CI 0.13 to 7.72; 50 participants; low-certainty evidence). A single study of alteplase versus urokinase showed no clear difference in requirement for surgery (OR alteplase versus urokinase 0.46, 95% CI 0.04 to 5.24) but an increased rate of adverse effects, primarily bleeding, with alteplase (OR 5.61, 95% CI 1.16 to 27.11; 99 participants; low-certainty evidence). This translated into 154 (6 to 499 more) serious adverse events with alteplase compared with urokinase per 1000 people treated. AUTHORS' CONCLUSIONS In patients with complicated infective pleural effusion or empyema, intrapleural fibrinolytic therapy was associated with a reduction in the requirement for surgical intervention and overall treatment failure but with no evidence of change in mortality. Discordance between the negative largest trial of this therapy and other studies is of concern, however, as is an absence of significant effect when analysing low risk of bias trials only. The reasons for this difference are uncertain but may include publication bias. Intrapleural fibrinolytics may increase the rate of serious adverse events, but the evidence is insufficient to confirm or exclude this possibility.

Abstract
OBJECTIVE To describe the management and evolution of high risk of death pulmonary embolism associated with right heart thrombi. MATERIAL AND METHODS We conducted a prospective cohort survey over a 54 month-period, from March 1st, 2012 to September 30th 2015. Were included all patients with pulmonary embolism and having high or intermediate-high risk of death. Patients were divided into two groups according to whether cardiac Doppler-echography found a thrombus in the right chambers or not (ICT+ vs. ICT-). The survival curves for the patients were obtained using the software STATA. RESULTS The prevalence of pulmonary embolism associated with right heart thrombi was 4% in our study. Thrombi were mobile, straight localization in all cases. The ICT+group was characterized by a significantly higher proportion of congestive heart and chronic lung disease. The proportion of patients' thrombolysis was significantly higher in the ICT-group. In the ICT+group, thrombolysis significantly reduced mortality giving a 30-day survival of 80% against 20% among patients receiving only heparin. CONCLUSION Pulmonary embolism associated with right heart thrombi including the atrium are not exceptional. These patients are at high risk of early death. Thrombolysis is significantly improving the mortality of pulmonary embolism associated with right-sided heart thrombi.

Abstract
Failed reperfusion after thrombolytic therapy for acute myocardial infarction is common and signifies a poor prognosis. We investigated the clinical consequences of non-resolution of the ST segment after thrombolytic therapy for acute ST-elevation myocardial infarction, in 85 consecutive patients admitted to a coronary care unit lacking rapid access to angioplasty. Failed thrombolysis was defined as <50% ST-segment resolution 180 minutes after the start of thrombolytic treatment. Outcomes were measured in terms of in-hospital adverse events, length of hospital stay, and mortality at 6 weeks and 1 year. Thrombolysis was successful, in terms of ST-segment resolution, in 45 patients (53%). After adjustment for other factors, ST resolution was the only independent predictor of an uncomplicated recovery in hospital (odds ratio 6.8, 95% confidence interval 2.3 to 19.9; P<0.001). At 6 weeks and 1 year, overall mortality was lower in the ST resolution group, though these differences became non-significant on multivariate analysis. In patients who survived to hospital discharge, median length of stay was greater in successfully thrombolysed patients (9 days versus 8 days) despite their lower rate of complications. ST-segment resolution is a useful marker of successful thrombolysis and relates to clinical outcome. If assessed routinely it might assist, along with other clinical markers, in the identification of low-risk patients who can be discharged early.

Abstract
Objectives We evaluated the impact of implementation of the TN-STEMI programme on various characteristics of the pharmacoinvasive group by comparing clinical as well as angiographic outcomes between the pre- and post-implementation groups. Methods The TN-STEMI programme involved 2420 patients of which 423 patients had undergone a pharmacoinvasive strategy of reperfusion. Of these, 407 patients had a comprehensive blinded core-lab evaluation of their angiograms post-lysis and clinical evaluation of various parameters including time-delays and adverse cardio- and cerebro-vascular events at 1 year. Streptokinase was used as the thrombolytic agent in 94.6% of the patients. Results In the post-implementation phase, there was a significant improvement in ‘First medical contact (FMC)-to-ECG’ (11 vs. 5 min, p < 0.001) and ‘Lysis-to-angiogram’ (98.3 vs. 18.2 h, p < 0.001) times. There was also a significant improvement in the number of coronary angiograms performed within 24 h (20.7% vs. 69.3%, p < 0.001). The ‘Time-to-FMC’ (160 vs. 135 min, p = 0.07) and ‘Total ischemic time’ (210 vs. 176 min, p = 0.22) also showed a decreasing trend. IRA patency rate (70.2% vs. 86%, p < 0.001) and thrombus burden (TIMI grade 0: 49.1% vs. 73.4%, p < 0.001) were superior in this group. The MACCE rates were similar except for fewer readmissions (29.8% vs. 12.6%, p = 0.0002) and target revascularizations at 1 year (4.8% vs. none, p = 0.002) in the post-implementation group. Conclusion The implementation of a system-of-care (hub-and-spoke model) in the pharmacoinvasive group of the TN-STEMI programme demonstrated shorter lysis-to-angiogram times, better TIMI flow patterns and lower thrombus burden in the post-implementation phase.

Abstract
BACKGROUND Acute coronary artery disease (CAD) is one of the main causes of death in today's world. Myocardial infarction (MI) tends to be more common among diabetic patients. One of the most effective and used (in our settings) methods of resolution of MI is administration of streptokinase (SK). This study was conducted with the aim to determine the efficacy of thrombolytic therapy in reduction of ST segment elevation in acute MI patients presenting with diabetes. METHODS A descriptive case series with selection of 130 patients through nonprobability purposive sampling was conducted at the Medical Departments of Services Hospital Lahore. The study was completed in 6 Months. Patients 18-80 years of age having either gender diagnosed with confirmed acute myocardial infarction were included in this study. All patients were then injected with streptokinase 1.5 mu. Pre S and Post SK ECGs were done and ST segment elevation measured also measuring reduction of ST segment. RESULTS The mean age of the patients was noted as 54.42±8.80 years. There were 62.31% males. Mean reduction in ST-segment elevation of the patients was noted as 58.53±26.01. The efficacy was achieved in 47.7% patients. CONCLUSIONS It is concluded that SK can be effective in almost half of diabetic patients with myocardial infarction.

Abstract
OBJECTIVE To investigate if neutrophil lymphocyte ratio (NLR) predicts in-hospital adverse events and mortality, and shortterm (30-day) mortality in ST-elevated myocardial infarction (STEMI) patients thrombolysed with streptokinase (SK). STUDY DESIGN An observational study. PLACE AND DURATION OF STUDY Rawalpindi Institute of Cardiology, from June 2014 till January 2015. METHODOLOGY The STEMI patients, thrombolysed with SK had blood samples at admission, analysed for complete blood counts and NLR calculated. They were grouped into two, low and high NLR, taking 4.50 as cut-off. Chi square test was used to compare rate of adverse events and death in hospital stay. Mann-Whitney test was used to compare median NLR between patients died and discharged alive. Logistic regression analysis was used to estimate predictive ability of NLR for 30-day mortality. RESULTS Atotal of 145 (45.3%) patients had complications; 49 (15.3%) died in hospital, and 13 (4.06%) died in 30 days. Patients in high NLR group had higher rate of complications (63.5% vs. 25.5%, p <0.0001) and death (19.2% vs. 11.1%, p=0.046) in hospital than those in low NLR group. Cardiogenic shock (27.5% vs.11.1%, p <0.0001), heart failure (19.2% vs. 7.2%, p=0.002), arrhythmias (18% vs. 6.5%, p <0.0001), reinfarct/angina (9.6% vs.2% p=0.004) occurred more in high NLR group. Median NLR in patients died was higher than those discharged alive (7.46 vs. 4.70, p <0.0001). Regression analysis showed NLR an independent predictor of mortality (OR 1.131 at 95% CI, p = 0.029). Age, serum creatinine, Killip class were other predictors (p=0.002 and p=0.02, respectively). ROC curve showed AUC 0.908 (p <0.0001). CONCLUSION Ahigh NLR predicted increased in hospital complication rate, and in-hospital as well as 30-day mortality in STEMI patients thrombolysed with streptokinase.

Abstract
We report on 10 patients with thromboembolic occlusion of the middle cerebral artery (MCA) who underwent local thrombolytic therapy. Six patients developed a MCA occlusion during long-standing interventional neuroradiological procedures, while four had a proven or suspected cardio-embolic stroke. Streptokinase or urokinase was applied by a microcatheter placed into the thrombus within six hours of clinical onset. Complete or partial revascularization was achieved in all patients. Recovery was complete in seven and partial in three of the patients. In two patients, minor haemorrhagic transformation of the infarct occurred, which did not lead to neurological deterioration. It is concluded that in a selected group of patients with MCA occlusion, local thrombolytic therapy represents a safe and effective therapy.

Abstract
The authors retrospectively review the clinical course and outcome of 6 pediatric patients, ranging in age from 2 to 13 years, who were treated with TPA for complex empyema. Efficacy was assessed by evaluating pleural fluid drainage for 6 hours prior to and subsequent to each dose of TPA, as well as by resolution of fever and length of hospital stay. The average volume drained for 6 hours before infusion of TPA was 22.5 mL ± 18.4 mL, and the average volume 6 hours after TPA therapy was 141.7 mL ± 28.3 mL, P < .0001. After initiation of TPA therapy, 5 out of 6 patients became afebrile within 48 hours. The median length of stay after initiation of TPA therapy was 6 days, with a range from 4 days to 12 days. A discussion of other current therapies for empyema, along with a comparison of these therapies to TPA regarding the costs of therapies and risk-benefit ratios, is also included.

Abstract
OBJECTIVE: To describe the use of adjunctive therapies in patients with acute myocardial infarction receiving thrombolytic agents. DESIGN: Data were collected prospectively by the study-site investigator or the emergency department physician caring for the patient. Study participation did not influence thrombolytic regimen selection or the adjunctive therapies ordered. SETTING: Thirteen Virginia hospitals representing a cross-section of hospitals in the state. Eleven are urban medical centers; four have graduate medical education programs. PARTICIPANTS: Patients were included in the study if the decision to administer thrombolytic therapy was made in the emergency department. MAIN OUTCOME MEASURES: Concomitant medications administered during the first six hours after initiation of thrombolytic therapy. RESULTS: Two hundred ten patients (aged 57 ± 14.1 y) were evaluated. Ninety-five percent of these patients were treated with tissue plasminogen activator, 3 percent received anisoylated plasminogen streptokinase activator complex, and 2 percent received streptokinase. Ninety-one percent of the patients also received heparin, the most commonly used adjunctive medication; 77 percent concomitantly received lidocaine; 62 percent received aspirin; and only 19 percent received a beta-blocker. CONCLUSIONS: Our data provide a reference point for future studies to determine factors that influence the selection of adjunctive agents for treating patients with acute myocardial infarction receiving thrombolytics.

Abstract
Peripartum cardiomyopathy is a cardiac disease at high thromboembolism potential. The authors report a case of peripartum cardiomyopathy admitted for congestive heart failure. Echocardiography found a dilated cardiomyopathy with severely impaired left ventricular systolic function and biventricular thrombi. During hospitalization his condition was complicated by severe bilateral pulmonary embolism and left lower limb arterial acute thrombosis. The treatment consisted of thrombolysis with streptokinase associated with dobutamine (in addition to the conventional treatment of heart failure and bromocriptine). The outcome was favorable, marked by pulmonary and lower limb arterial unblocking.

Abstract
Hemorrhagic complications of thrombolytic therapy are rare but also serious and sometimes life-threatening. Liver hematoma is a very uncommon complication following thrombolytic therapy. We present a rare case of sub-capsular liver hematoma following streptokinase therapy of acute myocardial infarction as a challenging condition. This case report highlights that emergency physicians and cardiologists should be familiar with the significant and uncommon complications of thrombolytic agents, particularly streptokinase which is used generally in under- developed countries.

Abstract
Deep vein thrombosis (DVT) is a major health problem in pregnancy and postpartum period. Catheter-directed thrombolysis (CDT) is safe and effective in the management of symptomatic DVT. Value of CDT in postpartum DVT is not fully evaluated. We describe five patients presenting with acute iliofemoral DVT in their early postpartum period who were treated with mechanical thromboaspiration and CDT. The CDT was done using streptokinase infusion and unfractionated heparin. Percutaneous angioplasty was done in patients with symptomatic residual lesion following thrombolysis. Patients were discharged with oral anticoagulant and compression stockings. This approach was successful in all five cases. Percutaneous endovascular therapy using CDT, mechanical thromboaspiration, and balloon angioplasty is safe and effective in iliofemoral DVT in postpartum period.

Abstract
BACKGROUND Pleural fluid loculations due to complicated parapneumonic effusion (CPE), empyema, tubercular effusion and traumatic hemothorax can be managed either by video-assisted thoracoscopic surgery (VATS) or intrapleural ibrinolytic therapy (IPFT). The former is more invasive, not easily available and is also more expensive. On the other hand, IPFT is less invasive, cheaper, easily accessible and if used early, in loculated pleural collections, break loculations and early pleural peel, thereby facilitating pleural space drainage. OBJECTIVE To study the efficacy of IPFT in facilitating pleural space drainage in loculated pleural collections of diverse aetiologies. METHODS A five-year retrospective, observational study of 200 patients, with loculated pleural collections and failed tube drainage and managed with IPFT was carried out. Responders were defined as those with significant volume of fluid drained and significant radiological resolution. RESULTS There were 106 (53%) cases of CPE, 59 (29.5%) cases of tubercular effusion, 23 (11.5%) cases of empyema and 12 (6%) cases of hemothorax. Responders were 148 (74%) in number. The distribution of responders as per type of loculated pleural collection was as follows: CPE 88 (83%), tubercular 37 (62.7%), empyema 14 (60.8%) and traumatic hemothorax 11 (91.6%). The adverse effects were mild and included chest pain in six patients and low-grade transient fewer in three cases. CONCLUSIONS Intrapleural fibrinolytic therapy is a safe and cost-effective option in the management of selected patients with loculated pleural effusions.

Abstract
Experience of active tactics of treatment application in 18 patients, suffering an acute thrombosis in system of lower vena cava, is presented. Possibilities were estimated and efficacy of active surgical tactics proved in continuing deep vein thrombosis on early stage were estimated. Active tactics, using catheter--governed thrombolysis, permits to escape pulmonary thromboembolism and to reduce a severity of further chronic venous insufficiency.

Abstract
BACKGROUND Left-sided prosthetic valve thrombosis (PVT) is a serious complication of valve replacement. In developing countries, fibrinolysis with streptokinase (SK) is often used as the first line of treatment. Anti-streptokinase (anti-SK) antibodies are widely prevalent in the general population, but their effect on the efficacy and outcome of fibrinolysis with SK in patients with PVT is not known. METHODS Patients with rheumatic heart disease and prosthetic valve replacement presenting with a first episode of left-sided PVT were enrolled. All patients underwent fibrinolysis with SK. An indirect enzyme-linked immunosorbent assay was used to detect anti-SK antibodies before fibrinolysis. Relationship of these antibodies to the outcome of fibrinolysis was evaluated. RESULTS Forty-four patients treated for left-sided PVT were included. Thrombosis affected 33 mitral and 11 aortic prosthetic valves. On fibrinolysis with SK, 32 (73%) patients achieved complete success, whereas it was unsuccessful in the remaining 12 patients. There were 3 bleeding events, 1 stroke, and 3 deaths. Mean anti-SK antibody levels were not significantly different between patients who had complete success and those who did not (8.81 ± 2.43 vs 7.67 ± 1.26 Au/mL; P = .13) and did not correlate with the outcome after adjustment with other variables. Patients in New York Heart Association class III or IV had a greater chance of failed fibrinolytic therapy, even after adjustment for other prognostic variables (odds ratio 9.0; 95% CI 1.29-63.02; P = .027). CONCLUSION Anti-SK antibody titers are not associated with success of fibrinolytic therapy using SK in patients with left-sided PVT.

Abstract
Purulent pericarditis (PP) is a very serious condition with almost 100% mortality if untreated. Intrapericardial fibrinolysis is a preferred alternative to pericardectomy in the treatment of persistent PP, but there are no consensus guidelines on the standard protocol for this procedure in children. A 9-year-old boy was referred to the Medical Research Council Unit in The Gambia (MRC). He had been unwell for 18 days with a high continuous fever, cough, fast breathing, and dyspnoea on exertion. Prior to referral he had been treated for malaria and pneumonia with no improvement. At the MRC, he was diagnosed with purulent pericarditis caused by Staphylococcus aureus and after admission he was managed for 4 weeks with intravenous antibiotics, pericardial aspirations followed by saline lavage of the pericardium and intrapericardial antibiotic instillation. Despite these measures, massive re-accumulation of the purulent pericardial effusion continued. Once daily intrapericardial instillation of streptokinase at a dose of 18,000 i.u/kg diluted in 50 ml of normal saline, and saline washout of the pericardium after 2 hours was commenced on the 29th day of admission, in addition to the antibiotics. This technique of fibrinolysis employed for 2 days was effective in managing the persistent purulent pericarditis when pericardial aspiration and intravenous and intrapericardial antibiotics failed.

Abstract
When a previously healthy adult experiences atraumatic cardiac arrest, providers must quickly identify the etiology and implement potentially lifesaving interventions such as advanced cardiac life support. A subset of these patients develop cardiac arrest or periarrest due to pulmonary embolism (PE). For these patients, an early, presumptive diagnosis of PE is critical in this patient population because administration of thrombolytic therapy may significantly improve outcomes. This article reviews thrombolysis as a potential treatment option for patients in cardiac arrest or periarrest due to presumed PE, identifies features associated with a high incidence of PE, evaluates thrombolytic agents, and systemically reviews trials evaluating thrombolytics in cardiac arrest or periarrest. Despite potentially improved outcomes with thrombolytic therapy, this intervention is not without risks. Patients exposed to thrombolytics may experience major bleeding events, with the most devastating complication usually being intracranial hemorrhage. To optimize the risk-benefit ratio of thrombolytics for treatment of cardiac arrest due to PE, the clinician must correctly identify patients with a high likelihood of PE and must also select an appropriate thrombolytic agent and dosing protocol.

Abstract
AIM: To compare the efficacy and safety of recombinant streptokinase (rSK) and phenylephrine-based suppositories in acute hemorrhoidal disease.
METHODS: A multicenter (14 sites), randomized (1:1), open, parallel groups, active controlled trial was done. After inclusion, subjects with acute symptoms of hemorrhoids, who gave their written, informed consent to participate, were centrally randomized to receive, as outpatients, rSK (200000 IU) or 0.25% phenylephrine suppositories, which had different organoleptic characteristics. Treatment was administered by the rectal route, one unit every 6 h during 48 h for rSK, and up to a maximum of 5 d (20 suppositories) for phenylephrine. Evaluations were performed at 3, 5 and 10 d post-inclusion. The main end-point was the 5th-day complete clinical response (disappearance of pain and edema, and ≥ 70% reduction of the lesion size). Time to response and need for thrombectomy were secondary efficacy variables. Adverse events were evaluated too.
RESULTS: 5th day complete response rates were 83/110 (75.5%) and 36/110 (32.7%) with rSK and phenylephrine suppositories, respectively. This 42.7% difference (95%CI: 30.5-54.2) was highly significant (P < 0.001). The advantage was detected since the early 3rd day evaluation (37.3% vs 6.4% for the rSK and active control groups, respectively; P < 0.001) and was kept even at the late 10th day assessment (83.6% vs 58.2% for rSK and phenylephrine, respectively; P < 0.001). Time for complete response was significantly shorter (P = 0.031; log-rank test) in the rSK group (median: 4.9 d; 95%CI: 4.8-5.0) with respect to the active control (median: 9.8 d; 95%CI: 9.8-10.0). Thrombectomy was necessary in 1/59 and 8/57 patients with baseline thrombosis in the rSK and phenylephrine groups, respectively (P = 0.016). There were no adverse events attributable to the experimental treatment.
CONCLUSION: rSK suppositories showed a significant advantage over a widely used over-the-counter phenylephrine preparation for the treatment of acute hemorrhoidal illness, with an adequate safety profile.

Abstract
BACKGROUND AND OBJECTIVES Valvular thrombosis is a serious complication in patients with prosthetic heart valves. Traditional treatment is emergency surgery, but thrombolysis provides a non invasive alternative. In this paper we evaluate the efficacy and safety of thrombolysis in prosthetic heart valve thrombosis. METHODS Data of 68 patients diagnosed of prosthetic valve thrombosis, treated at the Institute of Cardiology and Cardiovascular Surgery, Havana during a 6-years period were analyzed. They received thrombolysis with a recombinant streptokinase infusion at 250,000 IU in 30 minutes followed by 100,000 IU/hour during 72 hours or less if the thrombosis resolved before. The evaluation was based on clinical and echocardiographic findings. RESULTS Affected sites were mitral (50 cases), tricuspid (9), and aortic (9). Mean time of prosthesis implantation was 6.8 years. The presentation form was generally heart failure (NYHA functional class III-IV) in 64 (94.1%) patients. Mean time interval between onset of symptoms and diagnosis was 10.6 days. There was total response to treatment in 58 (85.3%) patients, partial in 4 (5.9%) and failure in 6 (8.8%). Recombinant streptokinase overall dose was 5.1 x 10(6) IU and mean infusion time 50 hours. Major hemorrhagic complications were observed in two patients. Five embolic events occurred during thrombolysis. Four patients died. Rethrombosis was noted in 11 patients; 10 were retreated successfully with thrombolysis. CONCLUSIONS Thrombolysis with recombinant streptokinase is efficacious and safe for the treatment of prosthetic heart valve thrombosis. It does not contraindicate surgical treatment if there is no total response, because patient goes to surgery in better hemodynamic conditions with lower risk. Nowadays it can be considered as first-line treatment in all patients with prosthetic heart valve thrombosis regardless of functional class unless specific contraindications exist.

Abstract
BACKGROUND Peripheral arterial thrombolysis is used in the management of peripheral arterial ischaemia. Streptokinase was originally used but safety concerns led to a search for other agents. Urokinase and recombinant tissue plasminogen activator (rt-PA) have increasingly become established as first line agents for peripheral arterial thrombolysis. Potential advantages of these agents include improved safety, greater efficacy and a more rapid response. Recently drugs such as pro-urokinase, recombinant staphylokinase and alfimperase have been introduced. This is an update of a review first published in 2010. OBJECTIVES To determine which fibrinolytic agents are most effective in peripheral arterial ischaemia. SEARCH METHODS For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (last searched March 2013) and CENTRAL (2013, Issue 3) for randomised controlled trials (RCTs) comparing fibrinolytic agents to treat peripheral arterial ischaemia. SELECTION CRITERIA RCTs comparing fibrinolytic agents to treat peripheral arterial occlusion. DATA COLLECTION AND ANALYSIS Data were analysed for the outcomes vessel patency, time to lysis, limb salvage, amputation, death, complications including major haemorrhage, stroke, and distal embolization. MAIN RESULTS Five RCTs involving a total of 687 participants with a range of clinical indications were included. No new studies were included in this update. In one three-pronged study, vessel patency was greater with intra-arterial recombinant tissue plasminogen activator (rt-PA) than with intra-arterial streptokinase (P < 0.04) or intravenous rt-PA (P < 0.01). In participants with peripheral arterial occlusion there was no statistically significant difference in limb salvage at 30 days with either urokinase or rt-PA, though this may reflect the small numbers in the studies. Incidences of haemorrhagic complications varied with fibrinolytic regime but there was no statistically significant difference between intra-arterial urokinase and intra-arterial rt-PA. In the three-pronged study intravenous rt-PA and intra-arterial streptokinase were associated with a significantly higher risk of haemorrhagic complications than with intra-arterial rt-PA (P < 0.05). AUTHORS' CONCLUSIONS There is some evidence to suggest that intra-arterial rt-PA is more effective than intra-arterial streptokinase or intravenous rt-PA in improving vessel patency in people with peripheral arterial occlusion. There was no evidence that rt-PA was more effective than urokinase for patients with peripheral arterial occlusion and some evidence that initial lysis may be more rapid with rt-PA, depending on the regime. Incidences of haemorrhagic complications were not statistically significantly greater with rt-PA than with other regimes. However, all of the findings come from small studies and a general paucity of results means that it is not possible to draw clear conclusions.

Abstract
Pulmonary thromboembolism is a main cause of parturient mortality in the world. Recently there are few reports about a thrombolytic therapy use in parturient in medical publications. The article deals with a case of successful application of thrombolysis in a complex cardio-pulmonary resuscitation in parturient with massive pulmonary thromboembolism. Unexpected dyspnea and hypotension occurred in the 30 years old woman after elective caesarian operation. Syndrome S1-Q3 was fixed on an ECG monitor. Cardiac arrest was fixed in 10 minutes later. Streptokinase was administrated in a 1 hour after beginning of the resuscitation. Haemodynamic parameters recovered almost after the administration of streptokinase. Severe uterine bleeding occurred in 20 minutes after the administration. Uterine extirpation and tight tamponade of the small pelvis was performed for the bleeding stopping. Later a floating thrombus was diagnosed in the right femoral vein. Tromboectomy was performed. Convulsions had place on first and second day after the resuscitation. Cerebral edema was diagnosed by computed tomography. Consciousness occurred on the fourth day and the woman was weaned from the ventilator on the fifth day. The patient was discharged from the hospital on 20th day without neurological complications.

Abstract
Venous thrombo-embolism is a life threatening condition with often non specific presentation. The detection of massive pulmonary embolism in the intra and immediate post-operative period is not only difficult due to the variety of conditions with similar presentation, but the therapy for the same is complicated with concerns of surgical and intracranial bleeding precluding various options. We present a case of massive pulmonary embolism presenting as intraoperative hypotension with an increased alveolar to arterial CO2 gradient which was subsequently managed with an accelerated regimen of streptokinase without increased postoperative bleeding. Accelerated regimen of streptokinase may be used as a safe low cost alternative modality in selected cases of massive pulmonary embolism in the immediate postoperative period.

Abstract
INTRODUCTION The left main coronary artery aneurysm is rare, with an incidence of 0.1%, being the atherosclerosis its main etiology. Angiography is the gold standard for diagnosis and treatment. Depending on the severity of coexisting coronary stenosis, patients with left main coronary artery aneurysms can be effectively managed either surgical or pharmacologically. CLINICAL CASE We present a case of a 44 year-old male with a history of obesity, smoking and dyslipidemia, complaining of oppressive chest pain, dyspnea and diaphoresis. An electrocardiogram showed an ST-segment elevation on the anterior and lateral wall and positive enzymatic curve for infarction. He was initially treated with streptokinase with no reperfusion evidence after 3 hours of the onset of symptoms, so he underwent to rescue angioplasty. Angiography reported left main coronary artery aneurysm thrombosis. Afterwards, he presented cardiogenic shock and was revascularized with a coronary artery bypass graft of the mammary artery to the left anterior descending artery and the saphenous vein to the obtuse marginal, however he did not survive. Determination for 4G/5G PAI-1 polymorphism, glycoprotein IIIa PLA1/A2 gene and Glu298Asp polymorphism of the endothelial nitric oxide synthase gene was performed. CONCLUSIONS Left main coronary artery aneurysms are rare, finding ONE in an acute myocardial infarction is a serious situation because of the challenging reperfusion techniques that are implied, such as in this case. The search for genetic factors related with hypofibrinolysis could guide stratification and therapy towards medical surgical or interventional management.

Abstract
BACKGROUND The aim of this study was finding the association between anti- Streptokinase (SK) levels based on previous streptococcus infection and the clinical outcome of acute myocardial infarction (AMI) among Iranian patients after SK treatment. METHODS In this prospective study, 31 consecutive patients presented to the emergency room of a referral university hospital within six hours of the onset of symptoms of AMI were recruited over a 3-year period (2007-2010). Blood samples for the analysis of the effect of neutralizing antibodies to SK assays were obtained immediately on arrival at the hospital. In-hospital and out-hospital clinical outcome defined as including return of typical chest pain after 48 hours, appearance of complex arrhythmia after 24 hours, maximum CPK serum concentration during first three days of admission, Left Venticular Ejection Fraction (EF) on the last day of admission, surgical interventions (CABG, PTCA), re-MI and re-admission due to cardiac problems during the one-year follow-up. RESULTS Overall, 31 patients (7 female, 24 male with the mean age of 56.83 +/- 2.21 years) were included in this study. The recurrence of typical ischemic chest pain 48 hours after AMI, appearance of complex arrhythmia during the admission to CCU and 24 hours after AMI, maximum CPK serum concentration during the first three days of admission, and left EF on the last day of admission were not significantly different between the two compared groups (p > 0.05). CONCLUSION According to this study, previous exposure to streptococcal infections may not reduce the efficacy of a single dose of SK and it does not seem necessary that its titer be measured before SK administration.

Abstract
Arterial thromboses are rare in newborns, mostly caused by arterial catheters. Neonatal arterial thrombosis occurring in other contexts is much rare. We report arterial thrombosis, not caused by catheterisation in 4 neonates hospitalised in the neonatology department of the Farhat Hached de Sousse hospital in Tunisia. The diagnosis of arterial thrombosis was made based on signs of ischemia in 2 patients affected by thrombosis of the iliac arteries. The symptoms were less clear: anuria associated with arterial high blood pressure in 1 patient affected by thrombosis of the abdominal aorta and by anuria with melena in a newborn with aortic and mesenteric thrombosis. Diagnosis was confirmed by Doppler sonography in 3 patients and based on autopsy data in 1 patient. A delay to consultation was noted in 3 patients, whose outcome was fatal. The progression was favourable after thrombolysis and anticoagulation using heparin in 1 patient with major aortic thrombosis. A review of the literature on the epidemiological, clinical, therapeutic and outcome data of the arterial thrombosis in the newborn child is provided.
