Abstract D-dimer and fibrinogen are nonspecific diagnostic biomarkers for venous thromboembolism (VTE). The aim of this article was to present the values of D-dimer and fibrinogen in relation to the anatomical localization of deep vein thrombosis (DVT). This was an observational study, which included 1,142 patients hospitalized from 2010 to 2019 at the Department of Angiology, Clinical Center University of Sarajevo. Data on gender, age, and thrombosis location were collected of all patients. Fibrinogen and D-dimer values were available for 983 and 500 patients, respectively. Thrombosis location was classified as iliofemoral (521–45.6% patients), femoral–popliteal (486–42.6% patients), isolated calf DVT (63–5.5% patients), and upper extremity DVT (UEDVT in 72–6.3% patients). A majority, 448 (89.6%), of patients had high D-dimer (the cutoff is 0.55 mg/L) and 662 (67.3%) patients had high fibrinogen (reference range: 1.8–3.8 g/L). The highest D-dimer was detected in patients with iliofemoral DVT (mean: 10.48 mg/L), χ2 = 50.78, p  = 0.00. The highest fibrinogen was detected in patients with iliofemoral DVT as well (mean 4.87 g/L), χ2 = 11.1, p  = 0.01. D-dimer and fibrinogen values are significantly higher in patients iliofemoral DVT than femoral–popliteal and isolated calf DVT, and D-dimer values are significantly higher in lower extremity DVT than UEDVT, but these biomarkers cannot be used alone to discriminate between thrombosis locations. Further imaging is required.

Abstract Aim: The study aimed to evaluate the acute effect of ultrafiltration on the mechanical properties of the aorta using brachial-ankle pulse wave velocity (PWV) before and after hemodialysis (HD). Patients and Methods: This study included 80 patients who were on a long-term HD program. The input variables were anamnestic data, body composition monitor (BCM) parameters, and echocardiography findings. The assessment of hydration status was determined by BCM, whose work is based on the principle of multifrequency bioimpedance spectroscopy. Another diagnostic procedure was the use of an arteriograph apparatus to assess PWV and Augmentation Index (AIx). All measurements were performed before and after dialysis on the middle dialysis day of the week. Results: The participants were divided into two groups based on hydration status: the experimental group consisted of 40 overhydrated participants and the control group consisted of 40 normovolemic participants. Statistically, the following BCM parameters correlated significantly positively with PWV: total body fat (r = 0.222; P < 0.05), overhydration (r = 0.290; P < 0.001), and relative overhydration (r = 0.290; P < 0.001). From echocardiography findings, only left atrial diameter correlated statistically significantly positively with PWV (r = 0.359; P < 0.001). Comparison of the mean PWV values within the experimental group before and after HD showed a statistically significant decrease from 14.32 ± 2.34 m/s to 8.72 ± 1.52 m/s (Z = 3.254; P = 0.0001). Mean PWV values within the control group did not decrease significantly from 13.39 ± 1.32 m/s to 10.39 ± 1.18 m/s (Z = 0.524; P = 0.742). If we compare the mean values of PWV between groups, then before HD treatment, there was no statistically significant difference between groups with PWV values in the experimental group of 14.32 ± 2.34 m/s and the control group of 13.39 ± 1.32 m/s (Z = 0.762; P = 0.852). According to the results of univariate regression analysis before and after HD treatment, only overhydration showed an absolute effect on PWV before and after HD. Conclusion: Overhydration showed an effect on brachial-ankle PWV before and after HD, and brachial-ankle PWV should be followed in HD patients.

Aim To investigate a profile of patients with peripheral artery disease (PAD) in Bosnia and Herzegovina. Methods This observational study included 1022 patients hospitalized at the Clinical Centre University of Sarajevo in a 5-year period, 2015 to 2019. Results Disease prevalence rises sharply after the age of 50. Most patients, 797 (78%) had proximal PAD; 658 (64.4%) were males. The death occurred in 73 (7.1%) patients, more often in females (66- 10%), and in patients with chronic kidney disease (10- 23.8%). Amputation occurred in 153 (15%) patients, where 102 (66.7%) patients had diabetes. Other surgical procedures were more common in males and smokers. Necrosis and phlegmon on lower extremities were found in 563 (55.1%) and 43 (4.2%) patients, respectively. History of tobacco use was noted in 620 (60.2%) patients, and 414 (40.8%) patients were current smokers. More than a half of patients had hypertension and diabetes, 596 (58.3%) and 513 (50.2%), respectively. One in 10 patients had a history of myocardial infarction or stroke. Most patients had high fibrinogen and blood glucose and low high-density lipoprotein (HDL). Conclusion Patients with PAD have multiple comorbidities and risk for various complications. Primary and secondary prevention of risk factors is the mainstay of treatment.

Churg-Strauss syndrome (CCS) or eosinophilic granulomatosis with polyangiitis is a rare condition, which is a challenge for both diagnosis and treatment in clinical work. Occurrences of cardiac complications represent a negative predictor of treatment outcome for these patients. The aim of this article is to present the diagnostic and therapeutic modality of a 33-year-old male diagnosed with? CCS. Treatment of these patients should be multidisciplinary, with a comprehensive therapeutic modality, while early diagnosis is imperative.

Introduction: Rheumatoid arthritis (RA) is a chronic, inflammatory, systemic rheumatic disease, very complex, with many different forms, progressive course, with pronounced changes in the joints, still unknown etiology and poorly understood pathology. Assessing of structural change can be done with proposed scores which observe changes on wrist and wrist joints, as a Sharp score. Aim: To examine the correlation between Anti-Citrullinated Protein Antibodies (Anti-CCP) values and Sharp score, and to determine the importance of Sharp score in the progression of RA. Methods: The study had prospective character and followed patients in the period from January 1, 2017 to December 31, 2017. The study included 40 patients with RA. At the beginning of the follow-up of patients, X-ray of hands and feet were performed. Results: Out of total of 40 patients, 34 or 85% had a follow-up examination after one year. Of these, 14 patients (41.2%) were reported to have complications. The subjects were divided into two groups according to Anti-CCP values. First group included patients with Anti-CCP values <4 and second those who had Anti-CCP> 4. Statistical analysis of the number of patients with complications at first and repeated examination indicated that there were no significant differences and that the sample was consistent between the first and repeated results (p> 0.05). Patients with higher Anti-CCP values also had a higher Sharp score with statistically significant differences during repeated examination (p <0.05). Correlation analysis shows that there was statistically significant (p <0.05) positive correlation with Anti-CCP values, and that an increase in values leads to an increase in the Sharp score (first measurement rho = 0.193, p> 0.05; repeated measurement rho = 0.645, p <0.0001). No statistically significant differences in Sharp score values at the first examination were compared with the repeated examination, but there was a statistically significant difference after one year in patients with complications (X2 = 13,388; p = 0.001), indicating that the Sharp score reflects disease progression. Conclusion: Anti-CCP values are also directly correlated with the Sharp score, which should be routine in both initial and repeated examination of a patient with RA. Sharp’s score represents a marker of progression as well as of therapeutic modality of RA.

Aim To determine a status of systolic function in patients with diabetes mellitus (DM) type 2 with ST-segment elevation acute myocardial infarction (STEMI), to determine values of cardiac biomarkers in patients with DM type 2 with STEMI and correlate the parameters with ejection fraction of left ventricle (EFLV). Methods A total of 80 patients were divided into two groups, the study group (group I) consisting of 40 patients admitted with the diagnosis of DM type 2 and STEMI, and a control group (group II) with 40 patients with STEMI without diagnosed DM type 2. Cardiac biomarkers - creatine kinase MB fraction (CKMB), and troponin I were monitored. The EFLV was evaluated echocardiographically (using Simpson method) five days after primary percutaneous coronary intervention (pPCI). Results In the group I the EFLV five days after pPCI was significantly correlated with troponin values (with a minimum r = -0.47; p=0.002, a maximum r = -0.339; p = 0.032, as well as with an average value of r = -0.389; p=0.013), and with an average CK value (r = -0.319; p=0.045). In the group II there was a significant negative correlation of EFLV with the maximum value of troponin (r = -0.309; p=0.05). Conclusion Troponin values have an effect on the EFLV after STEMI, and thus on the left ventricular status, as well as on the pharmacological modality itself.

Introduction: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease, with more frequent occurrence in the female gender, it primarily affects the lining of the synovial joints, and is associated with lower quality of life, inability to work, progressive disability, and all of these patients are more likely to develop other comorbidities. Aim: To display the role of anti-cyclic citrullinated peptide antibody (anti-CCP) in evaluating RA complications during a one-year follow-up, and compare its values with values of rheumatoid factor (RF). Methods: The study included 40 patients with RA, out of which 6 were excluded during the 1-year follow-up. All patients were treated with anti-rheumatics, methothrexate 15-25mg, occasionally corticosteroids at the same doses. Results: Anti-CCP values were also significantly higher during the second examination and were 5.0 ± 1.9 (range 0.5-7.6) compared to the first examination when they were 4.2 ± 1.3 (range 0.4-6.2) indicating a higher sensitivity of Anti-CCP in detecting of disease progression (t = -2.064; p = 0.043). Anti-CCP values were statistically significant in patients with complications compared to those without during the first examination and at follow-up after one year (t = 5,382; p = 0.0001). Conclusion: The positivity of anti-CCP antibodies is a useful marker in terms of predicting the course and prognosis of the RA. A higher titer of anti-CCP antibodies represents a poorer prognosis for the disease. Determination of the presence of anti-CCP antibodies should be performed as a routine examination in all patients with suspected rheumatoid arthritis.

Introduction: Lately, the use of biological therapy in various autoimmune diseases is increasing. The ideal marker for monitoring the effects of modern therapy is still non-existent. Aim: To investigate early response biomarkers of SLE and RA patients under the rituximab treatment are in research phase and each new investigations offer new and original useful data. Material and Methods: Immunophenotyping of cells was carried out by a standard method of sample preparation. We investigated by flow cytometric analyses expression of NK and CD19+ cells at ten SLE and five RA patients before and after treatment with rituximab, in laboratory of Department of Clinical immunology in the Clinical Centre University of Sarajevo. Results: In both cases, SLE and RA patients, reduced number of CD16+ parameter indicates lower cytotoxic activity of NK cells. Increased number of B cells indicates higher pathological activity leading to severe autoimmune disease allegation. Conclusion: Determining the proportion of NK and B will be useful diagnostic tool in therapeutic strategy, and also in monitoring of effect of biological therapy.

Introduction: By development of the medicine, control of the risk factors for acute myocardial infarction (AMI), became the foundation of cardiology. Aim: To investigate the association of the age with presence of risk factors in patients with acute myocardial infarction. Methods: The study had a prospective, comparative and descriptive character, and it was done on a sample of 80 patients (n=80; 55 male and 25 female) Clinic for Heart, Blood Vessel and Rheumatic Diseases, Clinical Center University of Sarajevo from January 2016 to August 2018. All patients were hospitalized under the diagnosis of myocardial infarction and were divided into two main groups, which were divided into two subgroups according to age. Group A, group of patients under 45 years of age at the moment of diagnosis of AMI (n = 40; men = 29; women = 11) was divided into group A1 (n = 20; patients aged 25-35 years) and group A2 (n = 20; patients aged between 35-45 years). Group B, patients older than 45 years at the time of diagnosis of AMI (n = 40; men = 26, women = 14) was divided into group B1 (n = 20; patients aged between 45-55 years) and group B2 (n = 20; patients aged 55-65 years of age). Results: According to gender distribution, there is a significantly higher incidence of hypertension in male patients aged 25-35 years and between 35-45 years (p = 0.01; p = 0.01). Increased cholesterol values were significantly more common in men aged 25-35 years (p = 0.0121). Increased triglyceride values were significantly more common in men aged 25-35 years, in comparison to female respondents of the same age (86.67% vs. 13.33%, p = 0.0001). There was a significant significance between the two groups in the occurrence of anteroseptal (p = 0.04) and in the diaphragmatic myocardial infarction (p = 0.01), while in other infarction localities no significant significance was observed. Conclusion: Male sex is a predisposing risk factor for the development of a cardiovascular incident in the younger age. The post infarction ejection fraction of the left ventricle was significantly reduced in younger patients. The potential for prevention should be of paramount importance. The localization of the incident itself, and the involvement of a certain blood, represents, regardless of all the research, still a fact that is hard to stratify and directly correlated with a certain risk factor.

Aim To assess triglyceride - to high-density lipoprotein cholesterol (TG/HDL)-C ratio in patients with acute coronary syndrome (ACS) and to verify its association with renal dysfunction. Methods A cross sectional study included 85 ACS patients divided in two groups with (ACS - RD) and without (ACS-nRD) presence of renal dysfunction, and 35 healthy subjects. Blood pressure, blood glucose, C-reactive protein, urea, creatinine, eGFR and serum lipids levels (total cholesterol, triglycerides, LDL-C, HDL-C) was measured in all participants. Based on the values of the measured lipid fractions TG/HDLc ratio was calculated. Results Patients in ACS group had significantly lower HDL-C level (p<0.0005) but significantly higher TG level (p=0.046) and TG/HDL-C ratio (p<0.0005) than controls. There was a significant increase (p<0.0005) in TG/HDL-C ratio in ACS-RD group compared to ACS-nRD group. The ACS-RD group had significantly higher level of TG (p=0.001), serum urea (p=0.02) and creatinine (p<0.0005) compared to the ACS-nRD group. With a cut-off level of 1.135 TG/HDL-C ratio had a sensitivity of 77.6% and a specificity of 62.9% in distinguishing between ACS patients and healthy subjects. With cut-off value of 1.905 TG/HDL-C ratio had a sensitivity of 75.9% and a specificity of 78.6% in distinguishing between ACS patients with and without renal dysfunction. Conclusion This study confirms the reliability of the TG/HDLC ratio as a simple, low cost and useful marker in distinguishing between patients with ACS and healthy subjects and ACS patients with and without renal dysfunction.
