D-Dimers Variability in the Perioperative Period of Breast Cancer Surgery Helps to Predict Cancer Relapse: A Single-Centre Prospective Study.

BACKGROUND: The importance of D-dimers (DD) assessment in the diagnostic algorithm of venous thromboembolic (VTE) disease is well known. Increase of DD concentration may be also associated with neoplastic disease. Many studies documented that high concentration of DD before solid tumour surgery indicates more advanced disease and poor life expectancy. The prognostic value of the DD concentration variability in the perioperative period, in women undergoing breast cancer surgery, has not been analysed so far. Thus, the aim of the present prospective study was to assess whether the trend of DD concentration changes in the perioperative period may predict cancer recurrence in women undergoing breast cancer surgery. MATERIALS AND METHODS: 189 consecutive women with histopathological diagnosis of breast cancer (BC) referred for surgical treatment were included. DD concentration was measured twice in each patient: at the time of admission to hospital and at the time of discharge home. Enoxaparin in standard dose of 40 mg daily s. c. was used as primary VTE prophylaxis in all of the patients. RESULTS: The recurrence of BC, within 1 year observation time, occurred in 13 patients (6.8%), in 11 (5.8%) patients with DD increase after surgery and only in 2 (1.1%) without an increase in DD, P = .0179. Increase in DD concentration after BC surgery was an independent positive predictor of disease relapse (OR 8.600, LCI 1.451, UCI 96.80, P = .0371) together with the lack of postoperative radiotherapy (OR 6.009, LCI 1.305, UCI 31.95, P = .0245), whereas the lack of postoperative chemotherapy predicted no BC relapse (OR .07355, LCI .0056, UCI .58, P = .0245). CONCLUSIONS: Increase of DD in the early postoperative period may be considered as additional independent predictor of recurrence of BC within 1 year.

Venous Thromboembolic Disease in COVID-19, Pathophysiology, Therapy and Prophylaxis.

For over two years, the world has been facing the epidemiological and health challenge of the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Growing problems are also complications after the development of COVID-19 in the form of post and long- COVID syndromes, posing a challenge for the medical community, both for clinicians and the scientific world. SARS-CoV-2 infection is associated with an increased risk of cardiovascular complications, especially thromboembolic complications, which are associated with both thrombosis of small and very small vessels due to immunothrombosis, and the development of venous thromboembolism. Low molecular wight heparin (LMHW) are the basic agents used in the prevention and treatment of thromboembolic complications in COVID-19. There is still a great deal of controversy regarding both the prevention and treatment of thromboembolic complications, including the prophylaxis dose or the optimal duration of anticoagulant treatment in patients with an episode of venous thromboembolism.

Intrapericardial recombinant tissue plasminogen activator in purulent pericarditis- case series.

BACKGROUND: Pericardial constriction is one of the complications of purulent pericarditis (PP). Most difficult to treat, which may develop both in early and in the late period of the disease, resulting in a very poor prognosis. CASE PRESENTATION: We present case series of 4 patients with purulent pericarditis, in whom direct intrapericardial administration of recombinant tissue plasminogen activator (r-tPA) was used. Management of PP requires a combined surgical and medical approach. The most important is complete drainage of the effusion by subxiphoid pericardiotomy connected with complementary use of broad-spectrum antibiotics. Despite the use of broad- spectrum antibiotics, in some patients a large volume of daily drainage is still present. Constrictive pericarditis as a complication of PP is observed in majority of patients. Intrapericardial administration of fibrinolytic agents, although not strongly recommended, can improve efficacy of antibiotic treatment especially in patients with loculation fluid and can prevent the development of constrictive pericarditis. r-tPA was applied at a dose of 20 mg dissolved in 100 ml of normal saline in a 100 ml syringe, administered by a large pericardial drain (Pezzer drain) installed into the pericardial cavity during pericardioscopy. The tube was closed and re-opened after 24 h. No serious complications, such as bleeding, allergy or hypotension, were noted. CONCLUSION: We present case series of 4 patients with purulent pericarditis, in whom direct intrapericardial administration of recombinant tissue plasminogen activator (r-tPA), prevented the development of constrictive pericarditis, and increased efficacy of antibiotic treatment without any significant complications.

Analysis of the accuracy of the Wells scale in assessing the probability of lower limb deep vein thrombosis in primary care patients practice.

BACKGROUND: The clinical picture of deep vein thrombosis (DVT) is nonspecific. Therefore assessment of the probability of occurrence of DVT plays a very important part in making a correct diagnosis of DVT. The aim of our prospective study was to assess the accuracy of the Wells scale in primary care setting in diagnostic procedure of suspected deep vein thrombosis. METHODS: In the period of 20 - months (from 2007 to 2009) a group of residents from one of the urban districts of Warsaw, who reported to family doctors (22 primary care physicians were involved in the study) with symptoms of DVT were assessed on the probability of occurrence of deep vein thrombosis using the Wells scale. Family doctors were aware of symptoms of DVT and inclusion patients to this study was based on clinical suspicion of DVT. Patients were divided into three groups, reflecting probability of DVT of the lower limbs. To confirm DVT a compression ultrasound (CUS) test was established. We analyzed the relationship between a qualitative variable and a variable defined on an original scale (incidence of DVT versus Wells scale count) using the Mann-Whitney test. Chi-square test compared rates of DVT events in all clinical probability groups. Patient were follow up during 3 months in primary care setting. RESULTS: In the period of 20 months (from 2007 to 2009) a total number of 1048 patients (male: 250 , female: 798 mean age: 61.4) with symptoms suggestive of DVT of the lower extremities entered the study. Among the 100 patients classified in the group with a high probability of DVT of the lower extremities, 40 (40%) patients (proximal DVT - 13; distal DVT - 27) were diagnosed with it (95% CI [30.94% -49.80%]). In the group with a moderate probability consisting of 302 patients, DVT of the lower extremities was diagnosed in 19 (6.29%) patients (95% CI [4.06% -9.62%]), (proximal DVT - 1; distal DVT - 18). Of the 646 patients with a low probability of DVT of the lower extremities distal DVT was diagnosed in 1 (0.15%) patient (95% CI [0.03% -0.87%]). CONCLUSION: The Wells scale used in primary care setting demonstrated a high degree of accuracy.

Pulmonary artery stenosis due to embryonal carcinoma with primary mediastinal location.

A 29-year old man was admitted to the intensive care unit after losing consciousness. On physical examination, a loud systolic murmur over the heart was found. Echocardiography revealed narrowing of pulmonary artery with high pressure gradient. Computed tomography of the chest revealed the presence of large tumour localised in the upper anterior mediastinum. Due to the risk of total closure of the pulmonary artery, interventional mediastinotomy was performed and diagnosis of carcinoma embryonale was established. Subsequent chemotherapy (BEP regimen) has brought regression of tumour and significant improvement in haemodynamic parameters (relief of pressure gradient in pulmonary artery). During the second surgery, the resection of all accessible tumour mass together with marginal resection of the right upper lobe was performed. No signs of cardiac or great vessels infiltration was found. Histopathologic examination revealed the necrotic masses and neoplastic foci diagnosed as teratoma immaturum. In a four-month follow-up the patient's condition remained good. The patient is still under the care of both oncological and cardiological specialists. Thus far he has not required further chemotherapy. Holter ECG monitoring revealed no arrhythmia, but the patient is still treated with mexiletine. The patient is planning to return to work.

New 6-Minute-Walking Test Parameter-Distance/Desaturation Index (DDI) Correctly Diagnoses Short-Term Response to Immunomodulatory Therapy in Hypersensitivity Pneumonitis.

The six-minute-walking test (6MWT) is an easy-to-perform, cheap and valuable tool to assess the physical performance of patients. It has been used as one of the endpoints in many clinical trials investigating treatment efficacy in pulmonary arterial hypertension and idiopathic pulmonary fibrosis. However, the utility of 6MWT in patients diagnosed with hypersensitivity pneumonitis (HP) is still under investigation. The aim of the present retrospective study was to assess the value of different 6MWT parameters, including the newly developed distance-desaturation index (DDI), to evaluate immunomodulatory treatment outcomes in HP patients. METHODS: 6MWT parameters (distance, initial saturation, final saturation, desaturation, distance-saturation product (DSP), and DDI) were analyzed at baseline and after 3 to 6 months of treatment with corticosteroids alone or in combination with azathioprine. RESULTS: 91 consecutive HP patients diagnosed and treated in a single pulmonary unit from 2005 to 2017 entered the study. There were 44 (48%) males and 52 (57%) patients with fibrotic HP (fHP). Sixty-three patients (69%) responded to treatment (responders) and 28 (31%) did not respond (non-responders). In the responders group, all parameters assessed during 6MWT significantly improved, whereas in non-responders, they worsened. Medians (95% CI) of best indices were post-treatment DDI/baseline DDI-1.67 (1.85-3.63) in responders versus 0.88 (0.7-1.73) in non-responders (p = 0.0001) and change in walking distance-51 m (36-72 m) in responders, versus 10.5 m (-61.2-27.9) in non-responders (p = 0.0056). The area under the curve (AUC) of receiver operating characteristics (ROC) for post-treatment DDI/baseline DDI was 0.74 and the optimal cut-off was 1.075, with 71% of specificity and 71% of sensitivity. CONCLUSIONS: 6MWT may be used as a tool to assess and monitor the response to immunomodulatory therapy in HP patients, especially if indices incorporating both distance and desaturation are used. Based on the present study results, we recommend 6MWD and DDI use, in addition to FVC and TL,co, to monitor treatment efficacy in patients with interstitial lung diseases.

Bronchoalveolar Lavage Cell Count and Lymphocytosis Are the Important Discriminators between Fibrotic Hypersensitivity Pneumonitis and Idiopathic Pulmonary Fibrosis.

BACKGROUND: Fibrotic hypersensitivity pneumonitis (fHP) shares many features with other fibrotic interstitial lung diseases (ILD), and as a result it can be misdiagnosed as idiopathic pulmonary fibrosis (IPF). We aimed to determine the value of bronchoalveolar lavage (BAL) total cell count (TCC) and lymphocytosis in distinguishing fHP and IPF and to evaluate the best cut-off points discriminating these two fibrotic ILD. METHODS: A retrospective cohort study of fHP and IPF patients diagnosed between 2005 and 2018 was conducted. Logistic regression was used to evaluate the diagnostic utility of clinical parameters in differentiating between fHP and IPF. Based on the ROC analysis, BAL parameters were evaluated for their diagnostic performance, and optimal diagnostic cut-offs were established. RESULTS: A total of 136 patients (65 fHP and 71 IPF) were included (mean age 54.97 ± 10.87 vs. 64.00 ± 7.18 years, respectively). BAL TCC and the percentage of lymphocytes were significantly higher in fHP compared to IPF (p < 0.001). BAL lymphocytosis >30% was found in 60% of fHP patients and none of the patients with IPF. The logistic regression revealed that younger age, never smoker status, identified exposure, lower FEV1, higher BAL TCC and higher BAL lymphocytosis increased the probability of fibrotic HP diagnosis. The lymphocytosis >20% increased by 25 times the odds of fibrotic HP diagnosis. The optimal cut-off values to differentiate fibrotic HP from IPF were 15 × 106 for TCC and 21% for BAL lymphocytosis with AUC 0.69 and 0.84, respectively. CONCLUSIONS: Increased cellularity and lymphocytosis in BAL persist despite lung fibrosis in HP patients and may be used as important discriminators between IPF and fHP.

Acute Eosinophilic Pneumonia Complicated with Venous Thromboembolic Disease-Diagnostic and Therapeutic Considerations.

Acute Eosinophilic Pneumonia (AEP) is a rare idiopathic disease caused by an accumulation of eosinophils in the pulmonary alveoli and interstitial tissue of the lungs. The onset of symptoms is acute; some patients develop respiratory failure. The diagnosis is based on clinical symptoms, diffuse interstitial infiltrates in the lungs on imaging studies, and eosinophilia exceeding 25% on bronchoalveolar lavage or pleural fluid smear. Smokers are primarily at increased risk for the disease. We present a case of venous thromboembolic disease (VTE) that developed in the course of AEP in a previously healthy male smoker. Complete remission of the disease was achieved with anticoagulation therapy combined with a low dose of steroids. Surprisingly, further diagnostics revealed the presence of thrombophilia: antithrombin (AT) deficiency and increased homocysteine level. According to our knowledge, this is the first case of VTE diagnosed in the course of AEP combined with thrombophilia.

Tuberculous Pericarditis-Own Experiences and Recent Recommendations.

Tuberculous pericarditis (TBP) accounts for 1% of all forms of tuberculosis and for 1-2% of extrapulmonary tuberculosis. In endemic regions, TBP accounts for 50-90% of effusive pericarditis; in non-endemic, it only accounts for 4%. In the absence of prompt and effective treatment, TBP can lead to very serious sequelae, such as cardiac tamponade, constrictive pericarditis, and death. Early diagnosis of TBP is a cornerstone of effective treatment. The present article summarises the authors' own experiences and highlights the current status of knowledge concerning the diagnostic and therapeutic algorithm of TBP. Special attention is drawn to new, emerging molecular methods used for confirmation of M. tuberculosis infection as a cause of pericarditis.

Large Pericardial Effusion-Diagnostic and Therapeutic Options, with a Special Attention to the Role of Prolonged Pericardial Fluid Drainage.

BACKGROUND: Large pericardial effusion (LPE) is associated with high mortality. In patients with cardiac tamponade or with suspected bacterial etiology of pericardial effusion, urgent pericardial decompression is necessary. AIM: The aim of the present retrospective study was to assess the short-term results of pericardial decompression combined with prolonged drainage in LPE. MATERIAL: This study included consecutive patients with LPE who had been treated with pericardial fluid drainage between 2007 and 2017 in the National Tuberculosis and Lung Diseases Research Institute. METHODS: Echocardiographic examination was used to confirm LPE and the signs of cardiac tamponade. Pericardiocentesis or surgical decompression were combined with pericardial fluid (PF) drainage. Short-term effectiveness of therapy was defined as less than 5 mm of fluid behind the left ventricular posterior wall in echocardiography. RESULTS: The analysis included 74 patients treated with pericardial fluid drainage (33 female and 41 male), mean age 58 years, who underwent pericardial decompression. Out of 74 patients, 26 presented with cardiac tamponade symptoms. Pericardiocentesis was performed in 18 patients and pericardiotomy in 56 patients. Median PF drainage duration was 13 days. In 17 out of 25 patients with neoplastic PF, intrapericardial cisplatin therapy was implemented. In 4 out of 49 patients with non-malignant PF, purulent pericarditis was recognized and intrapericardial fibrinolysis was used. Short-term effectiveness of the therapy was obtained in all of patients. Non-infective complications were noted in 16% of patients and infective ones in 10%. CONCLUSION: Pericardial decompression combined with prolonged PF drainage was safe and efficient method of LPE treatment.

Factors Predictive for Immunomodulatory Therapy Response and Survival in Patients with Hypersensitivity Pneumonitis-Retrospective Cohort Analysis.

Hypersensitivity pneumonitis (HP) is one of the interstitial lung diseases with clearly established diagnostic criteria. Nevertheless, pharmacologic treatment recommendations are still lacking. Most specialists use steroids as first-line drugs, sometimes combined with an immunosuppressive agent. Aim: The aim of the present retrospective study was to establish predictive factors for treatment success and survival advantage in HP patients. Methods: We analyzed the short-term treatment outcome and overall survival in consecutive HP patients treated with prednisone alone or combined with azathioprine. Results: The study group consisted of 93 HP patients, 54 (58%) with fibrotic HP and 39 (42%) with non-fibrotic HP. Mean (± SD) VCmax % pred. and TL,co % pred. before treatment initiation were 81.5 (±20.8)% and 48.3 (±15.7)%, respectively. Mean relative VCmax and TL,co change after 3−6 months of therapy were 9.5 (±18.8)% and 21.4 (±35.2)%, respectively. The short-term treatment outcomes were improvement in 49 (53%) patients, stabilization in 16 (17%) patients, and progression in 28 (30%) patients. Among those with fibrotic HP, improvement was noted in 19 (35%) cases. Significant positive treatment outcome predictors were fever after antigen exposure, lymphocyte count in broncho-alveolar lavage fluid (BALF) exceeding 54%, RV/TLC > 120% pred., and ill-defined centrilobular nodules in high-resolution computed tomography (HRCT). An increased eosinophil count in BALF and fibrosis in HRCT were significant negative treatment outcome predictors. The presence of fibrosis in HRCT remained significant in a multivariate analysis. A positive response to treatment, as well as preserved baseline VCmax (% pred.) and TLC (% pred.), predicted longer survival, while fibrosis in HRCT was related to a worse prognosis. Conclusion: Immunomodulatory treatment may be effective in a significant proportion of patients with HP, including those with fibrotic changes in HRCT. Therefore, future trials are urgently needed to establish the role of immunosuppressive treatment in fibrotic HP.

Echocardiographic signs of pulmonary hypertension in patients with newly recognized hypersensitivity pneumonitis, prevalence and clinical predictors.

BACKGROUND: Hypersensitivity pneumonitis (HP) is the third, according to frequency, interstitial lung disease, with the estimated incidence rate of 1-2/100,000. In HP patients, the extensive inflammatory lesions encompassing both small airways and lung parenchyma, as well as subsequent development of lung fibrosis, may result in respiratory insufficiency and secondary pulmonary hypertension (PH). The aim of the present retrospective study was to assess the prevalence of echocardiographic signs of PH and its' clinical predictors, in newly recognized HP patients. METHODS: Consecutive HP patients, recognized in single pulmonary unit between 2005 and 2017, in whom echocardiography was performed at diagnosis, entered the present study. HP diagnosis was verified in every patient according to current diagnostic recommendations. The results of high resolution computed tomography of the chest (HRCT) were re-evaluated by two independent radiologists, blinded to clinical data. Echocardiographic signs of PH were defined as pulmonary artery systolic pressure (PASP) exceeding 36 mmHg. Regression analysis was applied to calculate PH risk, and receiver operator characteristic curves (ROC) were plotted to investigate diagnostic utility of various parameters in PH prediction. RESULTS: PASP exceeding 36 mmHg was noted in 26 out of 70 patients (37%)-with equal frequency among patients with fibrotic and non-fibrotic HP. Significant predictors of PH on echocardiography were: partial oxygen tension in arterialized capillary blood (PaO2) <69 mmHg, lung transfer capacity for carbon monoxide (TLCO) <42% of predicted, six minutes walking test (6MWT) distance <455 meters, and 6MWT desaturation rate >8%. In case of TLCO <42% of predicted, probability of PH on echocardiography was increased by five-fold, in case of 6MWT desaturation rate >8%-by four fold. CONCLUSIONS: The best predictors of PASP >36 mmHg on echocardiography in HP patients at diagnosis were: TLCO <42% and 6MWT desaturation rate >8%. Neither the presence of lung fibrosis on HRCT, nor the duration of the disease or patients age, were helpful in PH prediction.

Exogenous lipoid pneumonia induced by nasal instillation of paraffin oil.

Lipoid pneumonia is a rare pulmonary disease, classified in terms of the source of lipid exposure into two variants: exogenous and endogenous. We present a patient with exogenous lipoid pneumonia, acquired after chronic exposure to paraffin oil-containing nasal drops. The diagnosis was established by demonstration of lipid-laden macrophages in bronchoalveolar lavage, chest computed tomography results and a history of lipid exposure.

Intrapericardial cisplatin combined with oral colchicine resulted in long term control of malignant pericardial effusion in the course of metastatic renal cancer.

Background Neoplastic pericardial effusion (NPE) represents a common cause of morbidity and mortality in patient with cancer. NPE presents frequently as cardiac tamponade, requiring urgent pericardiocentesis or pericardiotomy, with subsequent pericardial fluid drainage. Despite high effectiveness of such procedures, the recurrence of effusion is noted in 30- 60% of patients. Intrapericardial therapy with cisplatin was found to be effective in NPE due to lung and breast cancer. Its role in cardiac tamponade due to renal cancer is unknown. Case presentation We presented 82-year-old man with renal cancer who was admitted to the Intensive Care Unit because of threatening pericardial tamponade due to NPE . Urgent subxiphoid pericardiotomy was performed with subsequent evacuation of 1000ml of bloody fluid. On the inner surface of the pericardium several pink nodules were found. Histological examination revealed carcinoma clarocellulare. In view of the persistent high drainage of the pericardium, intrapericardial cisplatin therapy was performed. The first day after surgery colchicine 0.5 mg/day/po was also introduced. No side effects of this treatment were observed. The patient died 12- month later due to cancer progression and cachexia. No recurrence of pericardial effusion was observed. Conclusion This is the first case study demonstrating long-term efficacy and safety of intrapericardial cisplatin combined with oral colchicine in NPE due to metastatic renal cell carcinoma.

[The insufficiency of low molecular weight heparin (LMWH) prophylaxis in patients with hereditary antithrombin (AT) deficiency]. / Nieskutecznosc heparyn drobnoczasteczkowych w pierwotnej profilaktyce przeciwzakrzepowej u chorego z wrodzonym niedoborem antytrombiny (AT).

A 39 year old man with normal, stable blood pressure was admitted to the Cardio-Pulmonary Intensive Care Unit due to diagnosed spiral CT pulmonary embolism (PE) and deep venous thrombosis (DVT). In 1999, a hereditary antithrombin (AT) deficiency was confirmed in the presented case. In 2006, because of a knee injury, the patient was provided with a plaster cast and primary antithrombotic prophylaxis with low molecular weight heparin (LMWH) (80 mg of enoxaparin) was administered subcutaneously once a day (patient's weight was 80 kg). Despite prophylaxis PE and DVT occurred after 6 weeks of treatment. The patient was successfully treated with unfractioned heparin, repeated infusions of AT concentrate and oral anticoagulants (OA). Transient pulmonary hypertension documented by echocardiography and hemoptysis complicated course of PE. Secondary prophylaxis with OA, and INR maintenance between 2-3, was successfully continued.

[Thrombocytopenia probably heparin-induced in women with tumor of the heart and pulmonary embolism]. / Trombocytopenia prawdopodobnie poheparynowa (HIT) u chorej z guzem serca i zatorem tetnicy plucnej.

43 years old women with tumor of the right ventricle was admitted to ICU due to pulmonary embolism and suspicion for heparin-induced thrombocytopenia. Thrombocytopenia was successfully treated with Arixtra and the patient was qualified for the cardio surgery intervention. Heparin is widely used in treatment and prophylaxis of venous thromboembolism and other diseases. One of the most important adverse effect of treatment with heparin is heparin-inducted thrombocytopenia (HIT), which is one of the most frequent drug-induced, immune-mediated type of thrombocytopenia. If it is unrecognized is associated with significant morbidity and mortality. According to our knowledge this is first report of Arixtra usage in patient with suspicion of HIT in Poland.

Intrapericardial fibrinolysis in purulent pericarditis-case report.

Purulent pericarditis (PP) continues to result in a very serious prognosis and high mortality. The most serious complication of pericarditis is constriction. Intrapericardial administration of fibrinolytic agents, although controversial, can prevent the development of constrictions. We present the case of a 63-year-old man with purulent inflammation of the right knee who was admitted to the intensive care unit (ICU) via emergency room orthopedic evaluation because of purulent pericarditis. Subxiphoid pericardiotomy was urgently performed, with 1200 ml of thick purulent fluid evacuated. As prevention for pericardial constriction, it was decided to administer fibrinolysis to the patient's pericardial cavity. Administration of streptokinase was complicated by the occurrence of a severe retrosternal pain and intrapericardial bleeding. Due to insufficiency of antibiotic therapy, 17 days after complicated fibrinolytic therapy with streptokinase, it was decided to administer 20 mg of r-tPA directly into the pericardium. In the following days, there remained a high drainage of purulent secretions. Fever up to 38 °C was still observed despite the use of antibiotics. Nine days after first administration of r-tPA, it was decided to apply the next dose. Daily drainage decreased from 50 to 20 ml in successive days. No fluid accumulation and symptoms and signs of constrictions were observed in clinical examinations as well as in echocardiography performed during 7 years follow-up after discharge.
