Agreement Between Transthoracic Echocardiography and Computed Tomography Pulmonary Angiography for Detection of Right Ventricular Dysfunction in Pulmonary Embolism.

BACKGROUND: Right ventricular dysfunction (RVD) is the main determinant of mortality in patients with pulmonary embolism (PE). Thus, guidelines recommend the assessment of RVD with transthoracic echocardiography (TTE) or computed tomography pulmonary angiography (CTPA) among these patients. In this study, we investigated the agreement between TTE and CTPA for the detection of RVD. METHODS: This single-center retrospective study included patients who were diagnosed with CTPA and underwent TTE within the first 24 hours following the diagnosis. RESULTS: Two hundred fifty-eight patients met the inclusion criteria. In 71.3% (184) of them, CTPA and TTE agreed on both the presence and absence of RVD. There was a moderate agreement between the 2 tests (Cohen's kappa = 0.404, P <.001). The agreement between right ventricle dysfunction on TTE and the increased right ventricle/left ventricle (RV/LV) on CTPA was fair (Cohen's kappa = 0.388, P <.001). Three patients died due to PE, and another 5 patients required urgent reperfusion therapy. Overall, adverse outcomes occurred in 4% (8) of patients. The sensitivity of modalities in the detection of adverse outcomes was 100%. Transthoracic echocardiography was more specific compared to CTPA (43% vs. 28%). Statistically, flattening/bulging of the interventricular septum on TTE was significantly associated with adverse outcomes. No individual CTPA parameter was related to adverse outcomes. CONCLUSION: Both CTPA and TTE are reliable imaging modalities in the detection of RVD. However, TTE is more specific, and this may help in the identification and appropriate management of patients at higher risk of decompensation. A combination of CTPA parameters rather than individual RV/LV ratios increases the sensitivity of CTPA.

Diagnosis and Treatment Patterns of Chronic Thromboembolic Pulmonary Hypertension in Russia, Kazakhstan, Turkey, Lebanon, and Saudi Arabia: A Registry Study.

BACKGROUND: Patients with chronic thromboembolic pulmonary hypertension (CTEPH) in countries with limited resources have, to date, been poorly represented in registries. OBJECTIVE: This work assesses the epidemiology, diagnosis, hemodynamic and functional parameters, and treatment of CTEPH in Russia, Kazakhstan, Turkey, Lebanon, and Saudi Arabia. METHODS: A prospective, cohort, phase IV, observational registry with 3-year follow-up (n = 212) in patients aged ≥ 18 years diagnosed with CTEPH was created. Clinical, hemodynamic, and functional parameters were obtained at an initial visit, follow-up visits, and a final visit at the end of 3 years' observation or end of follow-up. Data were recorded on electronic case report forms. Parameters evaluated included 6-minute walking distance (6MWD), use of pulmonary endarterectomy (PEA), balloon pulmonary angioplasty (BPA), pulmonary hypertension (PH)-targeted therapy, and survival. All statistical analyses were exploratory and descriptive, and were performed in the overall population. RESULTS: The most common symptoms were typical of those expected for CTEPH. Almost 90% of patients underwent right heart catheterization at diagnosis or initial study visit. In total, 66 patients (31%) underwent PEA before the initial visit; 95 patients (45%) were considered operable, 115 (54%) were inoperable, and two (1%) had no operability data. Only 26 patients (12%) had been assessed for BPA at their initial visit. PH-targeted therapy was documented at diagnosis for 77 patients (36%), most commonly a phosphodiesterase type 5 inhibitor (23%). Use of PH-targeted therapy increased to 142 patients (67%) at the initial visit, remaining similar after 3 years. Use of riociguat increased from 6% of patients at diagnosis to 38% at 3 years. Between baseline and end of observation, results for patients with paired data showed an increase in 6MWD. Survival at the end of observation was 88%. CONCLUSIONS: These data highlight the current diagnosis and management of CTEPH in the participating countries. They show that early CTEPH diagnosis remains challenging, and use of off-label PH-targeted therapy is common. CLINICALTRIALS: gov: NCT02637050; registered December 2015.

Clinical efficacy, safety, tolerability, and survival outcome of long-term inhaled iloprost treatment in the management of pulmonary arterial hypertension: Data from prospective multicenter observational OPTION study.

OBJECTIVE: To evaluate clinical efficacy, safety and tolerability of long-term inhaled iloprost treatment in the daily practice for the management of pulmonary arterial hypertension (PAH). METHODS: A total of 115 patients with PAH on inhaled iloprost treatment were included. New York Heart Association (NYHA) functional class, brain natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, and 6-minute walk distance (6MWD) were recorded at baseline and at 3rd to 24th month visits. Safety and tolerability of iloprost treatment were also evaluated during follow-up, as were the survival, clinical worsening, and the related risk factors. RESULTS: The treatment was associated with an increase in the percentage NYHA functional class II (from 0.0% at enrolment to 36.2% at 24th month visit) patients but no significant difference was noted in 6MWD values. Clinical worsening was observed in 63.5% patients, while survival rate was 69.6%. NT-proBNP levels were significantly higher in non-survivors than in survivors (p=0.042). Cox regression analysis revealed the association of female sex [odds ratio (OR)=0.318; 95% confidence interval (CI), 0.128-0.792; p=0.014] and scleroderma-related PAH (OR=0.347; 95% CI, 0.140-0.860; p=0.022) with significantly lower risk (3.14 fold and 2.88 fold, respectively) of mortality. CONCLUSION: Our findings indicate favorable efficacy, safety, and tolerability of long-term iloprost treatment in the management of PAH, whereas improved NYHA functional class was not accompanied with a significant change in 6MWD values. Patient age was a risk factor for clinical worsening, while female sex, scleroderma subtype, and lower NT-proBNP levels were associated with significantly lower mortality risk.

Modeling and optimizing electro-persulfate processes using Fe and Al electrodes for paper industry wastewater treatment.

In this study, the treatment of paper industry wastewaters by the electrocoagulation (EC) process with a strong oxidant, persulfate addition, was investigated. Persulfate was activated by dissolution of Fe and Al from electrodes during the process. Central composite design method, being one of the response surface methods, was applied for the optimization of process parameters and the development of a mathematical model for chemical oxygen demand (COD) removal from paper industry wastewaters. The effects of S2O8 -2/COD ratio, current, pH, and reaction time, being the variables of process, were assessed on the efficiency of contaminant removal. For COD removal in EC processes in which Fe and Al electrodes were used, the model's correlation coefficients (R2) were determined as 90.14% and 87.46%, respectively. As the result of experimental study actualized under optimum conditions determined by the model in order to obtain maximum contaminant removal, COD removal efficiencies were determined as 63.5% and 72.8% respectively for the Fe electrode (S2O8 -2/COD ratio: 1.25, current: 4.14 A, pH: 6, and reaction time: 5 minutes), and the Al electrode (S2O8 -2/COD ratio: 0.5, current: 4.25 A, pH: 7.25, and reaction time: 25 minutes). Electro-activated persulfate process is an appropriate treatment alternative for COD removal from paper industry wastewaters.

[The clinical and polysomnographic differences between obese and non-obese patients with obstructive sleep apnea]. / Obez ve non-obez obstrüktif uyku apneli hastalar arasinda klinik ve polisomnografik farkliliklar.

INTRODUCTION: Obesity has been considered to be one of the important risk factor for obstructive sleep apnea (OSA). We aimed to investigate the clinical and polysomnographic differences of obese and non-obese OSA patients and how these differences, if any, can be reflected in our daily clinical practice. MATERIALS AND METHODS: The polysomnographic data of 157 consecutive patients that underwent a sleep study were analyzed. Ninety-nine adult patients with a diagnosis of OSA [apnea-hypopnea index (AHI) ≥ 5/hour] were retrospectively assesed in two groups in respect of obese (BMI ≥ 30 kg/m2) or non-obese (BMI <30 kg/m2) according to body mass index (BMI). The clinical and polysomnographic results of the patients in both groups were compared. RESULT: Between 2010 and 2011, 99 (31 K/68 M) of 157 patients underwent polysomnography were diagnosed with OSA (AHI ≥ 5/hour). Thirthy six patients with OSA (36.4%) were non-obese and 63 patients (63.6%) were obese. There were no differences in the symptoms related to OSA between two groups (p> 0.05). Although there was no statistical significance, the age of the obese patients (50.5 ± 12.7 years) was lower than those of the non-obese (54.9 ± 10.0 years) in polysomnography their total sleep time was shorter and sleep latency later, and sleep efficiency, arousal index, N3%, and REM% were lower and N1% was higher (p> 0.05). While in the obese OSA patients the AHI and Epworth Sleepiness sclae were higher (respectively; p= 0.028, p= 0.01), average oxygen saturation at sleep was lower (p<0.001). While obese OSA patients had similar ratio of hypertension and atherosclerotic heart disease with non-obese OSA patients, whereas diabetes mellitus was higher in obese OSA group (p= 0.036). The use of antidepressant drug was more common in the non-obese patients than the obese patients (p= 0.011). CONCLUSIONS: Although obese OSA patients have a more severe disease compared to nonobese OSA patients, there were no significant differences in clinical and polysomnographics findings between two groups. Should be noted that OSA may occur in non-obese patients.

[Assessing the knowledge in primary health care following an educational course structured in the context of GARD chronic airway diseases national control program]. / Türkiye kronik hava yolu hastaliklari önleme ve kontrol programi (GARD Türkiye) birinci basamakta çalisan hekim egitimi bilgi degerlendirme sonuçlari.

INTRODUCTION: Chronic obstructive pulmonary diseases are common causes of disease in the community and account for considerable percent of the caseload in primary health care facilities. For this reason, it is important to question and improve the knowledge of primary health care physicians. This study is designed to assess the level of knowledge for bronchial asthma and COPD of the primary healthcare physicians, both before and immediately after an educational course structured in the context of GARD Chronic Airway Diseases National Control Program. MATERIALS AND METHODS: The participating physicians attended an intensive educational course on asthma and COPD. Twenty five item questionnaires for asthma and COPD were administered to the participants both before and immediately after the end of the course. Contribution of education to the level of knowledge was investigated by comparing the percentages of the correct answers in the pre-and post-test. RESULT: From 11 different cities, 1817 and 1788 primary health care physician were attended to the asthma and COPD educations, respectively. The accuracy rate of ≥ 75% was obtained from only 4 questions in pre-test asthma questionnaire. On the contrary, in 15 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 45.8%, and this rate raised to 69.6% after education course. The accuracy rate of ≥ 75% could not be obtained from any of the questions in pre-test COPD questionnaire. On the contrary, in 19 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 42.0%, and this rate raised to 71.3% after education course. CONCLUSIONS: It has been shown that, in primary care settings, the level of knowledge in asthma and COPD should be enhanced and that this increase can be achieved with an education course.

The factors affecting survival in patients with bronchiectasis.

BACKGROUND/AIM: There is limited information about the rate and modifiers of mortality in noncystic fibrosis bronchiectasis. MATERIALS AND METHODS: This study enrolled a total of 56 bronchiectasis patients. Patients' body mass index, smoking habit, previous therapies, comorbid disorders, history of vaccination, bronchiectasis type and radiological extent, arterial blood gas analysis, respiratory function tests, and laboratory results were recorded. RESULTS: After a follow-up of 65.38 ± 18.62 months the overall mortality rate was 35.7%. The mean survival duration was 46.42 ± 8.25 months. Advanced age significantly increased mortality (HR: 2.031; CI: 0.991-4.072, P = 0.035). A significant correlation was found between mortality rate and the partial oxygen pressure level (HR: 0.886 (CI: 0.817-0.960); P = 0.039). Pulmonary artery pressure was directly proportional to mortality rate (HR: 9.015 (CI: 3.272-94.036); P = 0.03). There was also a significant correlation between Pseudomonas aeruginosa proliferation in sputum and mortality (HR: 7.014 (CI: 2.812-17.962); P = 0.00). Comorbidities increased mortality (HR: 1.984 (CI: 0.972-2.996); P = 0.04). CONCLUSION: Bronchiectasis is a disease with high mortality. Advanced age, comorbid conditions, reduced partial oxygen pressure, pulmonary hypertension, and Pseudomonas aeruginosa proliferation in sputum increase its mortality rate.

Comorbidities and their impact on chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a complex disease that is associated with devastating outcomes resulting from lung involvement and several comorbidities. Comorbidities could impact on symptomology, quality of life, the complications, the management, economic burden and the mortality of the disease. The importance of comorbidities originates from their impact on the outcome of COPD. The most frequent comorbidities in COPD are cardiovascular, endocrinological, musculoskeletal, phycological disorders and lung cancer. Almost 50% of the COPD patients have 3 or more comorbidities. The recent Global Initiative of Obstructive Lung Disease (GOLD) Guideline suggested proactive search and the treatment of the comorbidities. However, there is no certain evidence demonstrating that active treatment of comorbidities improve the outcomes of COPD. However, it is well known that several comorbidities such as cardiovascular disease and lung cancer have greater impact on mortality caused by COPD. Several studies have shown that Charlson Comorbidity index or more recenty COPD Specific Comorbidity Index (COTE) has been found to be related with mortality of COPD. This concise review intended to summarize the most frequent comorbidities in association with their impact on COPD.

The risk factors for late failure of non-invasive mechanical ventilation in acute hypercapnic respiratory failure.

INTRODUCTION: Non-invasive mechanical ventilation provides early improvement in most of the patients with acute hypercapnic respiratory failure. The aim of our study was to determine the risk factors for late failure of non-invasive mechanical ventilation in patients with acute hypercapnic respiratory failure. MATERIALS AND METHODS: Ninety three patients were prospectively evaluated. Non-invasive mechanical ventilation was accepted to be successful if the patient was discharged from the hospital without the need for intubation (group 1) and to be late failure if a deterioration occurred after an initial improvement of blood gases tension and general conditions (group 2). RESULTS: Non-invasive mechanical ventilation was successful in 62 (66.7%) patients. In 25 (26.9%) patients a late failure was observed. There was no difference between groups 1 and 2 in terms of pretreatment pH, PaCO2 and PaO2/FiO2. However, serum C-reactive protein level, Acute Physiology and Chronic Health Evaluation II (APACHE II) score and frequency of bronchiectasis and pneumonia were significantly higher and serum albumin level, Glasgow Coma Score, cough strength and compliance to non-invasive mechanical ventilation were significantly lower in group 2. CONCLUSION: The pretreatment high APACHE II Score and C-reactive protein level, low Glasgow Coma Score, albumin level, cough strength, bad compliance to non-invasive mechanical ventilation, the presence of bronchiectasis and pneumonia and absence of significance improvement in PaO2/FiO2 after treatment were determined as risk factors for non-invasive mechanical ventilation late failure.

Familial Behçet's disease of adult age: a report of 4 cases from a Behçet family.

A familial aggregation of Behçet's disease (BD) has long been noted. These studies have supported the direct role of HLA-B5 in the pathogenesis of BD. Despite the fact that familial clustering is characterized by genetic anticipation, accounting for the earlier disease onset in successive generations, we present two brothers and two cousins from the same family who were diagnosed when they were over twenty years old.We report these young adult patients to introduce the characteristics of familial aggregation of BD. In this article HLA-B*51 and Cw*16 positivities with adult onset were demonstrated.

[Smoking cessation in patients with cardiopulmonary diseases]. / Kardiyopulmoner hastaligi olanlarda sigaranin birakilmasi

OBJECTIVE: To determine the smoking cessation rates of outpatients with cardiopulmonary disease and the differences between non-cardiopulmonary diseases. METHODS: Two hundred and two active smokers with comorbid diseases were prospectively evaluated between September 2004 and January 2008 in this observational study. All of the patients answered Fagerstrom test for nicotine dependence with a regular questionnaire of general characteristics. Behavioral counseling therapies were administered to all of the subjects. Nicotine replacement therapy, bupropion or combination therapies were the pharmacological therapies after running the baseline spirometry and carbon monoxide oximetry tests. Subjects were classified as patients with cardiopulmonary disease (124) and non-cardiopulmonary diseases (78), based on medical history. Student t and Chi-square tests were used for statistical analyses. RESULTS: The age of smoking was similar but total amount of smoked tobacco was higher (p<0.05) in the cardiopulmonary diseases group. In this group, the main smoking cessation reason was the existing disease (51%) (p<0.05). There was no other significant difference between two groups including treatment protocols. The smoking cessation rates were less (40%) with high relapses (12%) in cardiopulmonary diseases group (p<0.01 and p=0.01 respectively). In the subgroup analysis, treatment procedures were equivalent (p>0.05). CONCLUSION: Results of this analysis confirm that, tobacco dependence is still a severe but necessary condition for the patients with cardiopulmonary diseases. Additionally neither of the treatment protocols was superior to the others.

Uso precoz de la ventilación mecánica no invasiva en pacientes con insuficiencia respiratoria hipercápnica aguda ingresados en una sala de neumología: estudio prospectivo / Early Use of Noninvasive Mechanical Ventilation in Patients with Acute Hypercapnic Respiratory Failure in a Respiratory Ward: A Prospective Study

FundamentoEn los últimos años, la localización óptima de los pacientes sometidos a ventilación mecánica no invasiva (VMNI) ha sido motivo de debate. El objetivo del presente estudio fue determinar la eficacia de esta técnica en pacientes con insuficiencia respiratoria hipercápnica aguda (IRHA), ingresados en una sala de neumología y los factores asociados a su fracaso.MétodosSe evaluaron prospectivamente 69 pacientes, tratados con VMNI, ingresados en una sala de neumología. Su eficacia se definió como la ausencia de necesidad de traslado a la unidad de cuidados intensivos (UCI) con el alta hospitalaria del paciente (grupo 1), definiéndose su fracaso como la necesidad de traslado a la UCI (grupo 2).ResultadosLa edad media fue significativamente mayor en el grupo 2. La causa de insuficiencia respiratoria fue una enfermedad pulmonar obstructiva crónica (EPOC) en 51 pacientes, síndrome de obesidad-hipoventilación en 14 y cifoescoliosis en 4. La VMNI fue satisfactoria en 55 pacientes e ineficaz en 14. No se identificaron diferencias significativas entre ambos grupos para los valores pretratamiento de pH, PaCO2 y PaO2/FiO2. Después de 1 y 3h de VMNI, hubo una mejora significativa en el grupo 1. Después de 3h de VMNI, en el grupo 1, la frecuencia respiratoria disminuyó significativamente. La puntuación pretratamiento obtenida en la APACHE II, la frecuencia respiratoria, frecuencia de neumonía, complicaciones asociadas y enfermedades comórbidas fueron significativamente más altas en el grupo 2. La tasa de eficacia fue mayor en pacientes con una adhesión adecuada a la VMNI(AU)

ConclusiónLa VMNI puede aplicarse eficazmente a pacientes con IRHA ingresados en una sala de neumología. Los factores asociados a su fracaso son la ausencia de una mejora inicial de los parámetros de la gasometría y de la frecuencia respiratoria, la falta de adhesión a la VMNI, una edad más avanzada, la presencia de complicaciones asociadas, enfermedades comórbidas, neumonía y una mayor frecuencia respiratoria basal(AU)

BackgroundIn recent years, the optimal location for noninvasive mechanical ventilation (NIMV) has been a matter of debate. Our aim was to detect the effectiveness of NIMV in acute hypercapnic respiratory failure (AHRF) in respiratory ward and factors associated with failure.Methods69 patients treated with NIMV in respiratory ward were prospectively evaluated. The success of NIMV was defined as absence of need for intensive care unit (ICU) transfer with patient's dishcarge from hospital (group 1), failure of NIMV was defined as need for ICU transfer (group 2).ResultsThe mean age was significantly higher in group 2. The cause of respiratory failure was COPD in 51 patients, obesity-hypoventilation syndrome in 14 and kyphoscoliosis in 4 patients. NIMV was successful in 55 patients and unsuccessful in 14. There was no significant difference between the two groups for pretreatment pH, PaCO2 and PaO2/FiO2. After 1h and 3h of NIMV there was significant improvement in group 1. After 3h of NIMV, in group 1 respiratory rate was significantly decreased. The pretreatment APACHE II score, respiratory rate, frequency of pneumoniae, associated complication and comorbid disease was significantly higher in group 2. The success rate was higher in patients with good compliance to NIMV.ConclusionNIMV can be succesfully applied in patients with AHRF in respiratory ward. The associated factors with NIMV failure are absence of early improvement in blood gases and respiratory rate, bad compliance to NIMV, older age, presence of associated complication, comorbid disease, pneumonia and high baseline respiratory rate(AU)

Associated factors with non-invasive mechanical ventilation failure in acute hypercapnic respiratory failure.

Our aim was to determine associated factors with non-invasive mechanical ventilation (NIMV) failure in acute hypercapnic respiratory failure ninety live patients treated with NIMV for acute hypercapnic respiratory failure were evaluated. While success of NIMV was defined as absence of need of intubation with the patient's discharge from hospital, failure of NIMV was defined as death or need of intubation. The pretreatment pH level was 7.30 in success and 7.28 in failure group (p> 0.05), PaCO(2) was 71.45 mmHg in success and 72.17 mmHg in failure group (p> 0.05). After 1h of NIMV, pH was 7.33 in success and 7.26 in failure group (p= 0.01), PaCO(2) was 65.50 mmHg in success and 73.47 mmHg in failure group (p= 0.02). After 1h of treatment, in success group there was significant increase of pH and decrease of PaCO(2) in contrast to baseline levels, while there was no significant change in failure group. The pretreatment Acute Physiology Assessment and Chronic Health Evaluation (APACHE) II score, serum C-reactive protein level and frequency of associated complication on admission were significantly higher and Glasgow Coma Score was lower in failure group. In conclusion, high APACHE II and C-reactive protein level, low Glasgow Coma Score, associated complication on admission and inadequate response in pH and PaCO(2) after first hour of NIMV are associated factors with NIMV failure.

[Update on pulmonary hypertension in chronic obstructive pulmonary disease]. / Güncel verilerle kronik obstrüktif akciger hastaliginda pulmoner hipertansiyon.

Secondary pulmonary hypertension (PH) is a well known possible feature in patients with chronic respiratory diseases. Owing to its frequency advanced chronic obstructive pulmonary disease (COPD) is the most common cause of PH. The studies that have focused on this topic have shown that PH is frequent during sleep, exacerbations or exercise but mean pulmonary artery pressure (PAP) is usually between 20 to 35 mmHg. Limited number of patients have severe PH, which is defined as >35 or 40 mmHg. Unfortunately, there is another subset of patients whom have minimal airway obstruction with greater PAP values called as 'out of proportion'. These two groups need special interest for further evaluation diagnosis and treatment strategy.

[Comparing the effectiveness of different treatment modalities on the smoking cessation rates]. / Farkli tedavi yöntemlerinin sigara birakma basarisi üzerine etkileri.

The social patterns of smoking have changed significantly in the past two decades but smoking is still as prevalent in the lowest socioeconomic groups as it was widespread. For the solution of this enormous problem many kinds of treatment modalities have been proposed but there is no single successful method for quitting. To determine the smoking cessation rates with behavioural treatment, behavioural + pharmacological treatments and compare the differences between each approaches. 371 smokers were prospectively evaluated between 2004 and 2008. At the beginning subjects were classified into two groups: behavioral treatment group (I) and pharmacological + behavioural treatment group (II). Numbers of patients per group were 88 and 283 respectively. According to pharmacological therapy group II was also divided into three subgroups: nicotine replacement treatment (NRT) (regardless of the type and dosage) (IIa), bupropion (IIb) and combination treatment modalities group (IIc). Numbers of patients per subgroups were 185, 70 and 28 respectively. All of the patients were attended the one year follow up visits. According to the baseline characteristics there was no significant difference between the groups and subgroups. At the end of the fist year, in group I smoking cessation rate was 41% and in group II 51% and this was not statistically significant (p< 0.05). In the sub group analysis the success rates for group IIa, IIb and IIc; 44.8%, 62.8% and 64% respectively and bupropion is significantly superior to the NRT (p= 0.01). In study subjects, smoking cessation rates were less with comorbid diseases (p= 0.004), baseline airway obstruction (p= 0.04) and high CO levels (p= 0.008). Results of this analysis confirm that, there is a significant difference between pharmacological treatment and behavioral treatments. Additionally, in the pharmacological approaches, bupropion seems to be superior. Besides, comorbid conditions have been a huge problem to solve.

Acute anuric renal failure with streptokinase therapy in a patient with acute venous thromboembolic disease and the review of renal side effects of streptokinase.

The benefits of thrombolytic therapy in acute myocardial infarction are now well established. However many uncertainties, such as adverse effects, are still remain in venous thromboembolic disease. We describe a unique patient who treated with streptokinase for the methylen tetrahydrofolate reductase mutation associated acute deep vein thrombosis and massive pulmonary embolism. After therapy patient developed acute anuric renal failure without an evidence of bleeding or immunologic reaction and we would like to review the renal side effects of streptokinase in patients with venous thromboembolic disease.
