RESUMO
BACKGROUND: A validated 4-point sputum colour chart can be used to objectively evaluate the levels of airway inflammation in bronchiectasis patients. In the European Bronchiectasis Registry (EMBARC), we tested whether sputum colour would be associated with disease severity and clinical outcomes. METHODS: We used a prospective, observational registry of adults with bronchiectasis conducted in 31 countries. Patients who did not produce spontaneous sputum were excluded from the analysis. The Murray sputum colour chart was used at baseline and at follow-up visits. Key outcomes were frequency of exacerbations, hospitalisations for severe exacerbations and mortality during up to 5-year follow-up. RESULTS: 13 484 patients were included in the analysis. More purulent sputum was associated with lower forced expiratory volume in 1â s (FEV1), worse quality of life, greater bacterial infection and a higher bronchiectasis severity index. Sputum colour was strongly associated with the risk of future exacerbations during follow-up. Compared to patients with mucoid sputum (reference group), patients with mucopurulent sputum experienced significantly more exacerbations (incident rate ratio (IRR) 1.29, 95% CI 1.22-1.38; p<0.0001), while the rates were even higher for patients with purulent (IRR 1.55, 95% CI 1.44-1.67; p<0.0001) and severely purulent sputum (IRR 1.91, 95% CI 1.52-2.39; p<0.0001). Hospitalisations for severe exacerbations were also associated with increasing sputum colour with rate ratios, compared to patients with mucoid sputum, of 1.41 (95% CI 1.29-1.56; p<0.0001), 1.98 (95% CI 1.77-2.21; p<0.0001) and 3.05 (95% CI 2.25-4.14; p<0.0001) for mucopurulent, purulent and severely purulent sputum, respectively. Mortality was significantly increased with increasing sputum purulence, hazard ratio 1.12 (95% CI 1.01-1.24; p=0.027), for each increment in sputum purulence. CONCLUSION: Sputum colour is a simple marker of disease severity and future risk of exacerbations, severe exacerbations and mortality in patients with bronchiectasis.

BACKGROUND: International guidelines recommend airway clearance management as one of the important pillars of bronchiectasis treatment. However, the extent to which airway clearance is used for people with bronchiectasis in Europe is unclear. The aim of the study was to identify the use of airway clearance management in patients with bronchiectasis across different countries and factors influencing airway clearance use. METHODS: This was a prospective observational study using data from the European Multicentre Bronchiectasis Audit and Research Collaboration (EMBARC) Registry between January 2015 and April 2022. Prespecified options for airway clearance management were recorded, including airway clearance techniques, devices and use of mucoactive drugs. RESULTS: 16 723 people with bronchiectasis from 28 countries were included in the study. The mean age was 67â years (interquartile range 57-74â years, range 18-100â years) and 61% were female. 72% of the participants reported daily sputum expectoration and 52% (95% CI 51-53%) of all participants reported using regular airway clearance management. Active cycle of breathing technique was used by 28% of the participants and airway clearance devices by 16% of participants. The frequency of airway clearance management and techniques used varied significantly between different countries. Participants who used airway clearance management had greater disease severity and worse symptoms, including a higher daily sputum volume, compared to those who did not use it regularly. Mucoactive drugs were also more likely to be used in participants with more severe disease. Access to specialist respiratory physiotherapy was low throughout Europe, but particularly low in Eastern Europe. CONCLUSIONS: Only a half of people with bronchiectasis in Europe use airway clearance management. Use of and access to devices, mucoactive drugs and specialist chest physiotherapy appears to be limited in many European countries.

BACKGROUND: Asthma is commonly reported in patients with a diagnosis of bronchiectasis. OBJECTIVE: The aim of this study was to evaluate whether patients with bronchiectasis and asthma (BE+A) had a different clinical phenotype and different outcomes compared with patients with bronchiectasis without concomitant asthma. METHODS: A prospective observational pan-European registry (European Multicentre Bronchiectasis Audit and Research Collaboration) enrolled patients across 28 countries. Adult patients with computed tomography-confirmed bronchiectasis were reviewed at baseline and annual follow-up visits using an electronic case report form. Asthma was diagnosed by the local investigator. Follow-up data were used to explore differences in exacerbation frequency between groups using a negative binomial regression model. Survival analysis used Cox proportional hazards regression. RESULTS: Of 16,963 patients with bronchiectasis included for analysis, 5,267 (31.0%) had investigator-reported asthma. Patients with BE+A were younger, were more likely to be female and never smokers, and had a higher body mass index than patients with bronchiectasis without asthma. BE+A was associated with a higher prevalence of rhinosinusitis and nasal polyps as well as eosinophilia and Aspergillus sensitization. BE+A had similar microbiology but significantly lower severity of disease using the bronchiectasis severity index. Patients with BE+A were at increased risk of exacerbation after adjustment for disease severity and multiple confounders. Inhaled corticosteroid (ICS) use was associated with reduced mortality in patients with BE+A (adjusted hazard ratio 0.78, 95% CI 0.63-0.95) and reduced risk of hospitalization (rate ratio 0.67, 95% CI 0.67-0.86) compared with control subjects without asthma and not receiving ICSs. CONCLUSIONS: BE+A was common and was associated with an increased risk of exacerbations and improved outcomes with ICS use. Unexpectedly we identified significantly lower mortality in patients with BE+A.

Background: High-Flow Nasal Cannula (HFNC) oxygen therapy emerged as the therapy of choice in COVID-19-related pneumonia and moderate to severe acute hypoxemic respiratory failure (AHRF). HFNC oxygen therapy in COVID-19 has been recommended based its use to treat AHRF of other etiologies, and studies on assessing outcomes in COVID-19 patients are highly needed. This study aimed to examine outcomes in COVID-19 patients with pneumonia and severe AHRF treated with HFNC. Materials and methods: The study included 235 COVID-19 patients with pneumonia treated with HFNC. Data extracted from medical records included demographic characteristics, comorbidities, laboratory parameters, clinical and oxygenation status, clinical complications, as well as the length of hospital stay. Patients were segregated into two groups based on their oxygen therapy needs: HDU group, those who exclusively required HFNC and ICU group, those whose oxygen therapy needed to be escalated at some point of hospital stay. The primary outcome was the need for respiratory support escalation (noninvasive or invasive mechanical ventilation) and the secondary outcome was the in-hospital all-cause mortality. Results: The primary outcome was met in 113 (48%) of patients. The overall mortality was 70%, significantly higher in the ICU group [102 (90.2%) vs. 62 (50.1%), p < 0.001]. The rate of intrahospital infections was significantly higher in the ICU group while there were no significant differences in the length of hospital stay between the groups. The ICU group exhibited significant increases in D-dimer, NLR, and NEWS values, accompanied by a significant decrease in the SaO2/FiO2 ratio. The multivariable COX proportional regression analysis identified malignancy, higher levels of 4C Mortality Score and NEWS2 as significant predictors of mortality. Conclusion: High-Flow Nasal Cannula oxygen therapy is a safe type of respiratory support in patients with COVID-19 pneumonia and acute hypoxemic respiratory failure with significantly less possibility for emergence of intrahospital infections. In 52% of patients, HFNC was successful in treating AHRF in COVID-19 patients. Overall, mortality in COVID-19 pneumonia with AHRF is still very high, especially in patients treated with noninvasive/invasive mechanical ventilation.
RESUMO
BACKGROUND: The aim of the study was to assess the effect of baricitinib on 28-day all-cause mortality and the progression of respiratory failure in patients needing transfer to the intensive care unit (ICU) with COVID-19 pneumonia treated with high-flow oxygen therapy. METHODS: This retrospective study included hospitalized patients with COVID-19 pneumonia treated with high-flow oxygen non-invasive ventilation receiving standard of care (SOC) or SOC in addition to baricitinib. Data on patients' characteristics, pro-inflammatory markers, D dimer, and National Early Warning Score 2 (NEWS2) values were collected and compared between groups. The primary endpoint was 28-day all-cause in-hospital mortality and the secondary outcome was transfer to the ICU. RESULTS: The study included 125 patients. The primary outcome was observed in 44.8% of them: 27% in the baricitinib group vs. 62% in the SOC group, p < 0.001. Transfer to the ICU ward was significantly lower in the baricitinib group: 29% vs. 81%, p < 0.001. A significant improvement was observed when the baricitinib group was compared to SOC in procalcitonin, CRP, D-dimer, neutrophil-to-lymphocyte ratio values, and NEWS2. CONCLUSION: Treatment with baricitinib in addition to SOC was associated with reduced mortality and a lower prevalence of transfer to the ICU in hospitalized patients with COVID-19 pneumonia treated with high-flow oxygen non-invasive therapy.
RESUMO
Pseudomonas aeruginosa is responsible for chronic infection in many bronchiectasis patients but it is not known whether it is associated with worse clinical outcomes independent of the underlying severity of disease.This study analysed data from 2596 bronchiectasis patients included from 10 different bronchiectasis clinical centres across Europe and Israel, with a 5-year follow-up period. Prevalence of P. aeruginosa chronic infection and its independent impact on exacerbations, hospitalisations, quality of life and mortality was assessed.The prevalence of P. aeruginosa chronic infection was 15.0% (n=389). P. aeruginosa was associated with a higher mortality in a univariate analysis (hazard ratio (HR) 2.02; 95% (confidence interval) CI 1.53-2.66; p<0.0001) but an independent impact on mortality was not found in a multivariate analysis (HR 0.98; 95% CI 0.70-1.36; p=0.89). P. aeruginosa was independently associated with increased mortality only in patients with frequent exacerbations (two or more per year) (HR 2.03; 95% CI 1.36-3.03; p=0.001). An independent association with worse quality of life of 7.46 points (95% CI 2.93-12.00; p=0.001) was found in a multivariable linear regression. P. aeruginosa was therefore found to be independently associated with exacerbation frequency, hospital admissions and worse quality of life. Mortality was increased in patients with P. aeruginosa particularly in the presence of frequent exacerbations.

RATIONALE: Exacerbations are key events in the natural history of bronchiectasis, but clinical predictors and outcomes of patients with frequently exacerbating disease are not well described. OBJECTIVES: To establish if there is a "frequent exacerbator phenotype" in bronchiectasis and the impact of exacerbations on long-term clinical outcomes. METHODS: We studied patients with bronchiectasis enrolled from 10 clinical centers in Europe and Israel, with up to 5 years of follow-up. Patients were categorized by baseline exacerbation frequency (zero, one, two, or three or more per year). The repeatability of exacerbation status was assessed, as well as the independent impact of exacerbation history on hospitalizations, quality of life, and mortality. MEASUREMENTS AND MAIN RESULTS: A total of 2,572 patients were included. Frequent exacerbations were the strongest predictor of future exacerbation frequency, suggesting a consistent phenotype. The incident rate ratios for future exacerbations were 1.73 (95% confidence interval [CI], 1.47-2.02; P < 0.0001) for one exacerbation per year, 3.14 (95% CI, 2.70-3.66; P < 0.0001) for two exacerbations, and 5.97 (95% CI, 5.27-6.78; P < 0.0001) for patients with three or more exacerbations per year at baseline. Additional independent predictors of future exacerbation frequency were Haemophilus influenzae and Pseudomonas aeruginosa infection, FEV1, radiological severity of disease, and coexisting chronic obstructive pulmonary disease. Patients with frequently exacerbating disease had worse quality of life and were more likely to be hospitalized during follow-up. Mortality over up to 5 years of follow-up increased with increasing exacerbation frequency. CONCLUSIONS: The frequent exacerbator phenotype in bronchiectasis is consistent over time and shows high disease severity, poor quality of life, and increased mortality during follow-up.

BACKGROUND: Patients with bronchiectasis often have concurrent comorbidities, but the nature, prevalence, and impact of these comorbidities on disease severity and outcome are poorly understood. We aimed to investigate comorbidities in patients with bronchiectasis and establish their prognostic value on disease severity and mortality rate. METHODS: An international multicentre cohort analysis of outpatients with bronchiectasis from four European centres followed up for 5 years was done for score derivation. Eligible patients were those with bronchiectasis confirmed by high-resolution CT and a compatible clinical history. Comorbidity diagnoses were based on standardised definitions and were obtained from full review of paper and electronic medical records, prescriptions, and investigator definitions. Weibull parametric survival analysis was used to model the prediction of the 5 year mortality rate to construct the Bronchiectasis Aetiology Comorbidity Index (BACI). We tested the BACI as a predictor of outcomes and explored whether the BACI added further prognostic information when used alongside the Bronchiectasis Severity Index (BSI). The BACI was validated in two independent international cohorts from the UK and Serbia. FINDINGS: Between June 1, 2006, and Nov 22, 2013, 1340 patients with bronchiectasis were screened and 986 patients were analysed. Patients had a median of four comorbidities (IQR 2-6; range 0-20). 13 comorbidities independently predicting mortality rate were integrated into the BACI. The overall hazard ratio for death conferred by a one-point increase in the BACI was 1·18 (95% CI 1·14-1·23; p<0·0001). The BACI predicted 5 year mortality rate, hospital admissions, exacerbations, and health-related quality of life across all BSI risk strata (p<0·0001 for mortality and hospital admissions, p=0·03 for exacerbations, p=0·0008 for quality of life). When used in conjunction with the BSI, the combined model was superior to either model alone (p=0·01 for combined vs BACI; p=0·008 for combined vs BSI). INTERPRETATION: Multimorbidity is frequent in bronchiectasis and can negatively affect survival. The BACI complements the BSI in the assessment and prediction of mortality and disease outcomes in patients with bronchiectasis. FUNDING: European Bronchiectasis Network (EMBARC).

INTRODUCTION: Although bronchiectasis particularly affects people ≥65 years of age, data describing clinical characteristics of the disease in this population are lacking. This study aimed at evaluating bronchiectasis features in older adults and elderly, along with their clinical outcomes. METHODS: This was a secondary analysis of six European databases of prospectively enrolled adult outpatients with bronchiectasis. Bronchiectasis characteristics were compared across three study groups: younger adults (18-65 years), older adults (66-75 years), and elderly (and ≥76 years). 3-year mortality was the primary study outcome. RESULTS: Among 1258 patients enrolled (median age: 66 years; 42.5% males), 50.9% were ≥65 years and 19.1 ≥ 75 years old. Elderly patients were more comorbid, had worse quality of life and died more frequently than the others. Differences were detected among the three study groups with regard to neither the etiology nor the severity of bronchiectasis, nor the prevalence of chronic infection with P. aeruginosa. In multivariate regression model, age (OR: 1.05; p-value: <0.0001), low BMI (OR: 2.63; p-value: 0.02), previous hospitalizations (OR: 2.06; p-value: 0.006), and decreasing FEV1 (OR: 1.02; p-value: 0.001) were independent predictors of 3-year mortality, after adjustment for covariates. CONCLUSION: Bronchiectasis does not substantially differ across age groups. Poor outcomes in elderly patients with bronchiectasis might be directly related to individual's frailty that should be further investigated in clinical studies.

INTRODUCTION: Shortage of intensive care beds has led to more frequent use of noninvasive ventilation (NIV) outside respiratory units, and data on NIV efficacy and safety on general wards is lacking. OBJECTIVE: The aim was to identify potential predictors for NIV failure. METHODS: This was a retrospective analysis of patients treated with NIV at the Institute for Pulmonary Diseases of Vojvodina from 2009 to 2013. Demographics, blood gases, chest radiographs, setting, and outcomes were analyzed to identify predictors of NIV failure. RESULTS: A total of 138 patients (65% men, mean age 66 ± 11 years) were treated with NIV. Indications for NIV were acute exacerbation of chronic obstructive pulmonary disease (85%) and cardiogenic pulmonary edema (7%), as well as respiratory insufficiency related to obesity and central hypoventilation (5%) and neuromuscular disease (3%). Rate of NIV failure was 34.8%. In 86 patients NIV was applied in the High Dependency Unit (HDU), while 52 received NIV on the general ward. Baseline characteristics in terms of gender, arterial blood gases, and the extent of consolidation on chest radiographs were similar. Patients treated in HDU were younger (64.4 ± 1.2 vs. 69.4 ± 1.5 years, p < 0.001). NIV on the general ward compared to HDU had higher rates of NIV failure (28/52 vs. 20/86, p < 0.001). Presence of consolidation involving two or more quadrants on chest radiograph (55% vs. 29%, p < 0.001) was associated with NIV failure. When adjusted for age and the extent of consolidation on chest radiograph, NIV failure was still less likely in patients treated in HDU (OR 0.23, 95% Cl 0.10-0.50). CONCLUSION: Patients with consolidation on chest X-ray and patients treated with NIV outside of dedicated respiratory units are at a higher risk for NIV failure.

INTRODUCTION: Achalasia is a rare esophageal disorder which, due to frequent presence of both respiratory and gastrointestinal symptoms, can initially be referred either to pulmonologist or gastroenterologist. CASE OUTLINE: A 50-year-old patient was initially referred to gastroenterologist with the following symptoms: nausea, vomiting, occasional hiccups, weight loss, chest pain, dysphonia, and dry cough. After chest X-ray, the patient was referred to pulmonologist with differential diagnosis for pulmonary infiltration and thoracic aortic aneurysm. Pulmonologist interpreted chest X-ray as showing paratracheal mediastinal enlargement with air-fluid levels, thus suspecting achalasia. Computed tomography scan of the thorax with per os contrast showed extremely dilated esophagus with food stasis. The patient was then referred to thoracic surgeon, who ordered additional diagnostics (esophageal passage with contrast, esophagomanometry, esophagogastroduodenoscopy), and finally performed Heller myotomy. Postoperatively there were no complications, and the patient was symptom free during the follow-up. CONCLUSION: Although achalasia can also result in respiratory symptoms, fastidious anamnesis and accurate radiological interpretation are essential for the correct diagnosis.

BACKGROUND AND AIMS: Determining clinical probability of pulmonary embolism (PE) with Wells scoring system is the first step towards diagnosis of PE. Definitive diagnosis of PE is confirmed by computed tomography pulmonary angiography (CTPA). METHODS: This was a prospective study on 80 patients referred to the Institute for Pulmonary Diseases of Vojvodina with suspected PE between April 2010 and August 2012. Clinical probability of PE was determined according to the Wells and modified Wells scoring system. CTPA was performed in 60 patients. The degree of pulmonary vascular obstruction was quantified by the Qanadli index. RESULTS: Low clinical probability of PE was present in one patient (1.6%), moderate in 43 (71.6%) and high in 16 (26.6%) patients. PE was confirmed in 50 (83.3%) patients. There were 21 patients (42%) whose Quanadli index was <25%, 18 (36%) between 25%-50%, while Quanadli index was ≥50 in 11 patients (22%). When compared to CTPA findings, modified Wells scoring system showed 90% sensitivity [95% confidence interval (CI) 78.2%-96.6%], and 20% specificity (95% CI 3.11%-55.6%), positive predictive value (PPV) 84.9% (95% CI 72.4%-93.2%) and negative predictive value (NPV) 28.6% (95% CI 4.5%-70.7%). There was weak positive correlation between Wells score and Quanadli index (r = 0.14; P = 0.29), without statistical significance. Wells score was significantly higher in haemodynamically unstable than in haemodynamically stable patients (6.8 vs 5.6, P = 0.014). There was no statistically significant difference between the values of Quanadli index in these two groups (31.33% vs 26.64%, P = 0.062). CONCLUSION: Modified Wells criteria have high sensitivity but low specificity in PE diagnostics. The Wells score does not correlate well with the Quanadli index.

INTRODUCTION: Sudden cardiac death is an unexpected natural death from cardiac causes. It is the most common and first manifestation of coronary artery disease. It accounts for 50% of mortality from cardiovascular disease in the United States of America and other developed countries, so measures that can reduce it are an important medical task. CASE REPORT: A 55-year old man suddenly lost consciousness at the train station in Novi Sad. An eyewitness provided first aid and ventricular fibrillation was converted to sinus rhythm by means of the automated external defibrillator. Emergency Medical Service Novi Sad soon arrived, continued resuscitation procedure, and transported the patient to the Cardiac Care Unit, who was then diagnosed with acutedmyocardial infarction and primary percutaneous coronary intervention was performed. Resuscitative hypothermia was applied in acute phase to prevent further brain injury. During further hospitalization the patient was stable, woke up from coma and early rehabilitation measures were implemented. After six months the patient had normal physical activities and there was no left ventricular segmental hypokinesia on echo cardiography. CONCLUSION: The application of all four chains of survival is important in increasing the survival rate of patients with sudden cardiac arrest.

Wegener's granulomatosis usually presents with clinical features of systemic vasculitis affecting lung, upper respiratory tract, kidney and even a nervous system. Yet, invasive pulmonary aspergillosis is characterised by invasion of blood vessels in the lungs, but the infection often spreads to kidneys, skin and central nervous system. We report a case of a 46-year-old male patient with no prior medical history. Clinical presentation included epistaxis, hemoptysis, hematuria and proteinuria, along with pulmonary nodular infiltrates. Differential diagnosis included invasive aspergillosis and Wegener's granulomatosis, but the diagnosis was only confirmed after autopsy. Establishing diagnosis of invasive aspergillosis remains a challenge for clinicians in acute care setting.

BACKGROUND/AIM: Influenza A (H1N1) re-emerged in the human population during 2009. The aim of this study was to describe characteristics, laboratory findings, clinical presentation and treatment outcome among patients with influenza A (H1N1) infection. METHODS: The study was performed at the Institute for Pulmonary Diseases of Vojvodina including all the patients hospitalized at the Intensive Care Unit or High Dependency Unit with confirmed, probable or suspected Influenza A (H1N1) infection between November 6th, 2009 and April 13th, 2010. RESULTS: Among 64 patients Influenza A (H1N1) infection was confirmed by rt-PCR in 50, defined as probable in 7 and as suspected in 6 patients. There was an equal number of male and female patients. Their mean age was 46 years (SD +/- 12.1). None of the patients were vaccinated against influenza. Comorbidities were present in 37 (58%) patients. There were 29 (45%) obese patients. Three patients were pregnant. The median time from symptom onset to hospital admission was 5 days (IQR 4-7). At admission, the median Modified Early Warning Score (MEWS) was 4 (IQR 3-6). The most common presenting symptoms were cough (100%) and fever (89%). The mean oxygen saturation at admission was 85.3% (SD 9.0). Auscultatory finding of wheesing in the absence of a chronic lung disease was found in 10 (15.6%) patients. Leukopenia was noted in 23 (35.9%) patients, and thrombocytopenia in 14 (21.9%) patients. Aspartate aminotransferase values were elevated in 41 (64.1%) patients, alanine aminotransferase in 32 (50%) patients, and creatine kinase in 36 (56.2%) patients. Opacities on an initial chest radiograph were predominantly patchy and the median number of the lung fields involved was 1 (IQR = 0-3). The non-survivors had statistically significantly higher MEWS at admission (p = 0.0001), lower oxygen saturation (p = 0.001), more lung fields involved on an initial chest radiograph (p = 0.006), wheezing in the absence of chronic lung disease (p = 0.02) and elevated aspartat aminotransferase (p = 0.02) and creatine kinase (p = 0.03). Acute respiratory disstress developed in 21 (32.9%) patients, and mechanical ventilation was required in 23 (36.1%) patients. Septic shock developed in 12 (18.7%) patients, and 19 (29.7%) patients had a multi-organ dysfunction. The overall hospital mortality was high--20.3% (95% CI, 11.3%-32.2%; n = 13), and especially so among the patients who required mechanical ventilation--56.5% (95% CI, 36.8%-74.40%). CONCLUSION: Timely initiation of antiviral therapy and early recognition of critically ill are important factors for reducing mortality.

OBJECTIVE: Narrow band imaging (NBI) videobronchoscopy is a new technique aimed at lung cancer detection. This study investigated its sensitivity and specificity for evaluation of lung cancer extension and its possible influence on therapeutic decision, compared with white light videobronchoscopy. METHODS: In this prospective study, we evaluated 106 patients with suspected lung cancer. All patients were examined using EVIS LUCERA videoendoscopy system. In every patient, at least three biopsies were taken from places visualized as pathologic, surrounding primary tumor, and three biopsies from places that appeared normal. The overall number of biopsies performed in 106 patients was 636. RESULTS: The specificity and sensitivity of NBI in revealing greater lung cancer extension were 85.6% and 95%, respectively; positive and negative predictive values were 84% and 95.6%, respectively. Specificity and sensitivity were significantly better when compared with white light bronchoscopy alone (P < 0.01). NBI led to the change in therapeutic decision in 14 patients. There was statistically significant correlation between NBI assessment of tumor extension and change in therapeutic decision (P < 0.000). CONCLUSIONS: NBI showed significantly better specificity and sensitivity in the assessment of lung cancer extension. NBI proved that it might have potential influence on therapeutic decision, making it more accurate. The procedure is safe and easily deployed in everyday practice.

INTRODUCTION: Generally speaking, thrombophilia includes all congenital and acquired conditions associated with increased susceptibility to thrombosis. An impaired balance between stimulating and inhibitory components of the hemostasis system may result in thrombosis or hemorrhage (extreme disorders), while moderately impaired hemostasis induces thrombophilia. THROMBOPHILIA, PRETHROMBOTIC STATE AND THROMBOSIS: A prethrombotic state is a condition of stimulated hemostasis system with tolerable intensity. When the activation level exceeds the capacity of inhibitory components, prethrombotic state advances to thrombosis. CLASSIFICATION OF THROMBOPHILIA: Thrombophilia is classified as primary or hereditary and secondary or acquired. Hereditary or congenital thrombophilia is a condition of congenital mutation of one or more antithrombotic components. Acquired or secondary thrombophilia accompanies a variety of pathologic conditions and diseases. LABORATORY DIAGNOSIS OF THROMBOPHILIA: Specific laboratory tests for congenital thrombophilia include assessment of the antigen component related to the activity of AT III, protein C, and protein S, evaluation of the resistance to the activated C protein, assessment of t-Pa and PAl-1 activity, as well as tests for hyperhomocysteinemia and prothrombin 20210 mutation. MANAGEMENT OF THROMBOPHILIA: Treatment of patients with congenital AT III deficiency includes intravenous heparin and AT III concentrate (dosage 50 U/ kgbw). Patients with heterozygous protein C and S deficiency are treated by intravenous heparin and oral anticoagulant therapy. Regarding arterial thrombosis due to confirmed congenital hyperhomocysteinemia, it is treated the same as venous thrombosis.
