RESUMO
INTRODUCTION: Calciphylaxis is a rare, but serious, kidney complication. Calciphylaxia is a vasculopathy of small blood vessels characterized by the deposition of calcium deposits in intimal arterioles with the consequent proliferation of intima, fibrosis and thrombosis. AIM: The aim was to show the significance of recognition of calciphylaxis relies on heightened clinical awareness of the presence of atypical skin nodules or ulcers that occur in patients with hemodialysis dependence and to characterize features of calciphylaxis or components of treatment that may lead to improved outcome. CASE REPORT: We present the case of 84-year-old woman with chronic kidney disease and diabetes mellitus as well as severely painful, firm, indurated plaques on the lower extremities. The plaques progressed to involve larger areas with associated local ulceration and necrosis. Laboratory testing revealed hyperparathyroidism and incisional skin biopsy confirmed calciphylaxis. Wound microbiology confirmed Staphylococcus aureus. CONCLUSION: The diagnosis can be based on clinical grounds, supported by histological analysis if possible. The laboratory workout must cover all the possible implications of chronic kidney disease with special attention to Ca+ and P+ values and evidence of skin or systemic infection. Calciphylaxis must be known by dermatologist as early diagnosis and proper management can be decisive for better prognosis.

INTRODUCTION: Plasmapheresis is often used as a therapy in the treatment of thrombotic thrombocytopenic purpura (TTP). TTP is manifested in thrombotic microangiopathy, consumed thrombocytopenia, hemolytic anemia and acute kidney injury with HUS development, neurologic dysfunction, and fever. CASE REPORT: we will present a case of a patient with acute kidney injury and refractory TTP at the beginning of hospitalization, subsequently manifested in secondary nephrotic syndrome. The patient was a female, 39 years of age, who as an emergency case was referred from the hospital in East Sarajevo to the Clinic of Endocrinology, Diabetes and Metabolism Disorders of the Clinical Center University of Sarajevo with suspected TTP. A few days before hospitalization she had a fever and vomiting, and therefore consulted her physician. She was hospitalized due to severe general condition, generalized edema, visible body hematomas, and diuresis amounting to 600 ml/12 hours. Laboratory results on admission were as follows: Leukocytes 19.5, Erythrocytes 3.23, Hemoglobin 103, Hematocrit 28.8%, Platelets 65.4 with few schistocytes and 2 reticulocytes, Sodium 140 mmol/L,, Potassium 4.5 mmol/L, Calcium 1.90 mmol/L, Glucose 7.9 mmol/L, Urea 37.5 mmol/L, Creatinine 366 umol/L,, Bilirubin 19.0 umol/L, Lactate dehydrogenase 1194 U /L. The patient was communicative, in cardiopulmonary sufficient state. Central venous catheter was placed in the right jugular vein and the first plasmapheresis was performed. During the hospitalization 38 plasmapheresis treatments with frozen plasma were performed, followed by three Rituximab treatment cycles. After the last plasmapheresis treatment a platelet count was 138. Also, parameters of the renal function were in their referent values. At the beginning of the treatment proteinuria was 19.6 g/24 hours urine. We were faced with a dilemma whether renal biopsy should be repeated in the future given that it might be the case of primary and not secondary nephrotic syndrome. Controlled proteinuria was 4.7g after plasmapheresis. The patient used only Prednisolone at a dose of 10 mg daily and although initially diagnosed with acute kidney injury she was not treated with dialysis. CONCLUSION: early diagnosis and early start of plasmapheresis therapy is vital for treatment of patients with acute kidney injury and TTP (HUS). A small number of patients is refractory to plasmapheresis and introducing Rituximab and plasmapheresis treatment is recommended.

INTRODUCTION: Based on the statistics the population in Bosnia and Herzegovina is getting older. In 2013 the average life span for women was 73.6 years and 68.1 for men. The chronic hemodialysis program is mainly reserved for elderly patients with high mortality risk. The most common cause of hemodialysis mortality relates to cardiovascular diseases (60.2%), regardless of frequent innovations and improvement of hemodialysis procedures. THE AIM OF THE STUDY: was to determine the mortality rate by age groups with comments on the presence of non-traditional predictors (anemia, hypoalbuminemia, CRP, vascular access and PTH) in dialysis patients in the follow-up period of 36 months. METHODS: The study included all patients undergoing chronic hemodialysis treatment at the Clinic of Hemodialysis of the Clinical Center University of Sarajevo (CCUS). RESULTS: Out of a total number of hemodialysis patients (n=232), the specific mortality rate in patients under 65 years of age was 16.8%, and 50.5% in patients over 65 years of age. According to the age groups the mortality rate in elderly patients is as follows: from 65 to 74 years (45.1%), from 75 to 84 years (55.0%), over ≥85 years (75.0%). The most frequent vascular access in patients under and above 65 is arteriovenous fistula (79.6% and 62.1 %), temporary hemodialysis catheter (11.7% and 43.8 %) and long-term hemodialysis catheter (8.8% and 4.2 %). In the age group under 65 years of age the temporary hemodialysis catheter is significantly and more frequently used in diseased patients in respect to survivors (34.8% vs. 7.0%) [χ(2)(2)=15.769, p=0.001]. Diseased patients from the age group over 65 had a significantly lower mean value of haemoglobin in blood (M=100.9±17.5 g/L) in respect to survivors (M=109.2±17.1)[t(93)=2.339; p=0.021], lower mean value of albumin in blood (Me=32.0; IQR=29.0 do 35.0) in respect to survivors (Me=34.0; IQR=32.0 to 38.0) [U=762.5; p=0.006], and higher mean value of CRP in blood (Me=19.3 mg/L; IQR=6.6 to 52.0) in respect to survivors (Me=7.8; IQR=4.0 to 16.7) [U=773.5; p=0.008]. Diseased patients belonging to the age group over 65 had lower mean value of PTH, but without statistical significance (p>0.05). CONCLUSION: older age, temporary vascular access, anaemia and hypoalbuminemia are strong predictors of mortality in hemodialysis patients. Old age does not present contraindication for hemodialysis treatment, and treatment of terminal renal illness should not be abandoned.
RESUMO
INTRODUCTION: Increased levels of C-Reactive Protein are found in 30-60% on hemodialysis patients and it is closely associated with the progression of atherosclerosis, cardiovascular morbidity and mortality. Non enzymatic antioxidants are antioxidants which primarily retain potentially dangerous ions of iron and copper in their inactive form and thereby prevent its participation in the production of free radicals. AIM: The aim of the study was to examine the relationship of CRP and non enzymatic antioxidants (albumin, ferritin, uric acid and bilirubin) i.e. examine the importance of CRP as a serum biomarker in assessing the condition of inflammation and its relationship to antioxidant protection in patients on hemodialysis. METHODS: The study was cross-sectional, clinical, comparative and descriptive. The study involved 100 patients (non diabetic) on chronic hemodialysis. The control group consisted of 50 subjects without subjective and objective indicators of chronic renal disease. In all patients, the concentration of CRP as well as concentrations of non enzymatic antioxidants were determined. RESULTS: In the group of hemodialysis patients 60% were men and 40% women. The average age of hemodialysis patients was 54.13 ± 11.8 years and the average age of the control group 41.72 ± 9.8 years. The average duration of hemodialysis treatment was 91.42 ± 76.2 months. In the group of hemodialysis patients statistically significant, negative linear correlation was determined between the concentration of CRP in and albumin concentration (rho = -0.251, p = 0.012) as well as negative, statistics insignificant, linear correlation between serum CRP and the concentration of uric acid (r = -0.077, p = 0.448). Furthermore, the positive, linear correlation was determined between serum CRP and ferritin (r = 0.159, p = 0.114) and positive linear correlation between CRP and total serum bilirubin (r = 0.121, p = 0.230). In the control group was determined a statistically significant, positive, linear correlation between serum CRP and uric acid concentration (rho = 0.438, p = 0.001) and statistically significant, positive, linear correlation between serum CRP and total serum bilirubin (rho = 0.510, p = 0.0001) A statistically significant, negative linear correlation was determined between CRP and albumin concentration (rho= -0.393, p = 0.005) as well as statistically significant, negative linear correlation between serum CRP and ferritin control group (rho = -0.391, p = 0.005). CONCLUSION: Elevated CRP level is a strong and independent predictor of low levels of serum albumin, which indicates that the hypoalbuminemia in hemodialysis patients could be more due to inflammation than malnutrition. There was no statistically significant correlation between CRP and other non enzymatic antioxidants (uric acid, ferritin, bilirubin), which shows that indicators of antioxidant defense in hemodialysis patients must be individually measured to determine their actual stocks and activity.
RESUMO
AIM: To determine the effect of a 16-week intradialytic exercise program consisting of 30 minutes of exercise during the first two hours of dialysis with three times a week frequency, on the quality of life (QoL), level of depression/anxiety and physical perfor- mance in hemodialysis (HD) patients. METHODS: The clinical, longitudinal, prospective study with one-group repeated measures design was conducted during a 16-week period. A convenience sample of 52 HD patients, who had been on HD for a minimum of 6 months, were included. QoL, level of depression and anxiety (questionnaires: SF-36, Back Depression Inventory (BDI) and Back Anxiety Inventory (BAI)) and physical performance (modifying Visual Analogue Scale (VAS) and Manual Muscle Testing (MMT)) were assessed at baseline and after 4-month exercise program. RESULTS: The following scales of SF-36 questionnaire were improved after 16-week exercise program: role functioning/emotional (P=0.01 8), energy/fatigue (P = 0.002) and social functi- oning (P = 0.030). Level of depression and anxiety were significantly decreased in males (P = 0.007 and P = 0.022, respectively) and females (P = 0.001 and P = 0.000, respectively). VAS scale and MMT were significantly increased in males (P = 0.000 and P = 0.001, respectively) and females (P = 0.01 9 and P = 0.001, respectively) after 16-week exercise program. CONCLUSION: Exercise program improves some aspects of QoL and physical performance, and decreases the level of depression and anxiety in HD patients.

INTRODUCTION: Central venous catheters in hemodialysis patients can be used as vascular access for hemodialysis. At our clinic, our doctors use temporary and tunneled catheters for hemodialysis treatment. The presence of the catheter, increases the risk of bacteremia in hemodialysis patients. Risk factors are nasal colonization with Staphylococcus aureus, prolonged use of catheters, previous bacteremia, anover dose of iron, low hemoglobin, low albumins, diabetes mellitus, and surgical procedures. The aim of this study was prevention of catheter sepsis and timely disclosures of existing and effective cures. PATIENTS AND METHODS: Thirty-eight patients with tunnelled catheters as vascular access for hemodialysis were included into the study. The study was conducted between January 1, 2011 and January 3, 2012. Outof 38 patients, 60% (23) were male and 40% (15) were female, while the average age was 67.48 +/- 13.9 years. The duration of hemodialysis treatment was 108.9 +/- 16.54 months. RESULTS: Over the study period, 9 patients developed bacteriemia associated with the use of catheter as a vascular approach. The incidence of infection in our study was 3.5 cases per 1000 catheter days. Two patients (5.2%) developed an infection in the first three months after the day of catheter placement, and the remaining 6 (15.8%) patients after one year of the use of catheter as a vascular approach. Regarding the causes of infection, in 3 (33%) patients these were gram-positive pathogens, in 5 (56%) patients gram-negative pathogens, and in one (11%) patient it was polimicrobe flora. According to the protocol and pending the outcome of susceptibility testing (antibiogram), all the patients were prescribed with antibiotic treatment therapy. In 7 (75%) patients tunnelled catheter was removed and replaced with temporary catheters for hemodialysis treatment. In 2 (25%) patients, was antibiotic-lock solution was injected into the catheter. There were no significant differences (p<0.05) in age, duration of dialysis treatment, hemoglobin levels, iron, transferrin saturation, ferritin and albumin in patients without infection and those who developed an infection. Only one patient has had a nasal colonization with Staphylococcus aureus. One patient developed severe thrombocytopenia, followed by sepsis anda lethal outcome due to heavy gastrointestinal bleeding. CONCLUSION: tunneled venous catheter is the increasingly common vascular access with the hemodialytic patients, but it is also a common cause of infection. Proper care and use of catheters, making the unique protocols of care and treatment algorithm occupy a significant place in each hemodialysis center. Our goal is to prevent the catheter sepsis, and to promptly detect the existing and a fast treatment of the same.

INTRODUCTION: Hepatitis C virus infection (HCV) is an important cause of morbidity and mortality in patients with end-stage renal disease (ESRD). PATIENTS AND METHODS: In this prospective, observational study, 205 patients, 37 (18%) of them with chronic HCV infection, were followed up for a one-year period at Department of Hemodialysis, Sarajevo Clinical Center, University of Sarajevo. The following parameters were analyzed: dialysis duration, sex, PCR RNA, HCV genotypes and biochemical parameters. Thirteen anti-HCV PCR RNA positive patients were treated with pegylated interferon alpha (Pegasys, Hoffman-La Roche). The goal of therapy was to reach sustained virologic response. The presence of anti-HCV antibodies in serum was detected by enzyme linked immunosorbent assay (ELISA). RESULTS: Of 37 anti-HCV positive patients, there were 20 (54%) males and 17 (45.9%) females with the mean hemodialysis duration of 143.67 +/- 57.64 months and mean age of 54.45 +/- 8.93 years. Of 37 anti-HCV positive patients, 30 (81.08%) patients were HCV RNA PCR positive. Among HCV RNA PCR positive patients, two had up to twofold elevated ALT values, one had twofold elevated AST values, and one had sixfold elevated GGT values. Thirteen RNA PCR positive patients were treated with pegylated interferon alfa for 48 weeks. Only one patient had genotype 1 virus. Upon therapy completion, only three patients were negative by PCR RNA (genotype 1b, 23.07%) at six months and yearly follow ups remained PCR negative. CONCLUSION: Sustained virologic response was achieved in three study patients. Monitoring guidelines for infection control, isolation of seropositive patients, and strict hygienic preventive measures can prevent HCV seroconversion in hemodialysis patients.

AIM: To evaluate frequency of CVD in dialysis population, in relationship to patients with and without diabetes, and their most common treatment. PATIENTS AND METHODS: This retrospective study included 187 patients, 106 males and 81 females, divided in two groups, diabetics and non-diabetics, treated by chronic hemodialysis. Patients' analyses included: anamnesis, ECG, chest X-rays, echocardiogram, laboratory examinations for calcium (Ca), phosphorus (P), parathormone (PTH), cholesterol (chol), triglicerids (TG), C-reactive protein (CRP), hemoglobin (Hb) and uric acid. In addition, we analyzed groups of drugs used by patients as prescribed by cardiologists. RESULTS: Average age was 58.0 years, most of them between 51 and 60. Average hemodialysis length was 4 years. Primary kidney diseases were pyelonephritis and glomerulonephritis. 19,78% of patients had diabetes. 165 patients (88,23%) had one or more cardiovascular diseases. 110 patients (58,2%) had hypertension, most of them used ACE inhibitors. Using test of multiple correlation, statistically significant correlations, among others, were shown between BMI and Ca, uric acid and P, albumin and PTH in diabetics, at the statistical significance level at p < 0.05. CONCLUSION: Cardiovascular diseases are the most common comorbidity and cause of mortality in hemodialysis population. There was no statistical significance in age, however there is a statistical difference in the dialysis duration variable, but in some biochemical laboratory parameters there was some difference. ACE inhibitors were most commonly used in the treatment of hypertension and systolic dysfunction, alone or with beta-blockers.

UNLABELLED: Patients with end stage renal disease (ESRD) have a reduced response to vaccination against hepatitis B infection. The aim of the study has been to determine the adequacy of immune response with new protocol of vaccination against hepatitis B infection. PATIENTS AND METHODS: The study included incident hemodialysis patients since 2008 until 2011 at the Clinic of Hemodialysis of the Clinical Center of the University of Sarajevo. We started the new vaccination protocol in September 2009. New protocol implied vaccination six month before starting renal replacement therapy (RRT) and "ic" (intracutaneously) application vaccine vs. "sc" (subcutaneously) application. Vaccination was carried out for over 12 months. The follow up period lasted from 2009 to 2011. RESULTS: The study included 64 patients, men were represented with 57,81% (37), and 42,19% women (27), who were divided in two groups. The first group included patients from the period from 2008 to 2009, who have been vaccinated under the old vaccination protocol, while the second group included patients with the new protocol from September 2009 to 2011. The first group had 28 patients, mean age of patients was 55,17 +/- 11.84 and mean duration of hemodialysis was 24,65 +/- 5,32 months. The second group had 36 patients, mean age of patients was 62,79 +/- 15,88 years, and mean duration of hemodialysis was 22,16 +/- 24,53 month. Neither group of patient has been previously vaccinated, nor these had positive in serum antiHBs before vaccination in second group. Five patients received a booster dose of vaccine, after which 4 showed adequate responses to anti HbS. In the first group of patients, out of total of 28 patients, 15 patients did not respond response with the adequate anti-HbS titer at the end of vaccination. In the second group of patients, out of 36 patients 31 of them responded to the vaccination with the new protocol, which was statistically significant (p<0,005). The total percentage of patients with adequate titer of antiHBs after vaccination towards a new protocol was 97.43% and the percentage of patients who required booster dose of vaccines was 12.82%. CONCLUSION: Vaccination of patients in ESRD,six months before renal replacement therapy and intradermal application of vaccine vs. subcutaneously, improved immune response of our patients.

Patients with End-Stage Renal Disease (ESRD) are at high risk of death as a result of the cardiovascular disease (CVD), which cannot be explained by the conventional risk factors only. Haemodialysis patients frequently have elevated serum concentrations of the cardiac troponins T, specific markers of myocardial injury. Plasma levels of brain natriuretic peptide (BNP) are elevated in fluid volume overload and heart failure, and decreased during dialysis. Currently, LV hypertrophy and LV dysfunction are considered the strongest predictors of cardiovascular mortality in dialysis population, and the synthesis of cardiac natriuretic peptides is high in the presence of alterations in the left ventricular (LV) mass and function. The aim of this study was to investigate the factors associated with the increased serum levels of BNP and CTN in haemodialysis patients, and their impact on cardiovascular morbidity. In this cross-sectional study we included 30 patients with ESRD, without coronary symptoms, who were subjected to regular dialysis treatment three times a week for the duration of four hours. Heart failure was defined as an ejection fraction (EF) of < 35%, and dyspnoea associated with either elevated jugular pressure or interstitial oedema evidenced in chest X-ray. All patients were in sinus rhythm at the time of the study. Twenty-five patients were on erythropoietin treatment. Blood samples were taken before and after the dialysis session. Our study included 30 patients (17 males, 13 females). The average age was 53,8 years (total range 31-74) divided into two groups: euvolemic and hypervolemic. The average dialysis time was 70,3+/-46,95 months. All haemodialysis patients had excessively high levels of BNP 2196,66+/-4553,86 ng/cm3. Plasma cTnT was found to be increased in 33,3% of patients. Patients with hypervolemia had significantly higher cTnT levels (0,0577+/-0,0436), as compared to the euvolemic patients 0,0184+/-0,0259 p<0,05. The elevated cTnT significantly correlated with the level of BNP (p<0,01), while average post-dialysis BNP was not significantly lower (1698,06+/-3499,15; R=0,191; p-ns.) as compared to the pre-dialysis BNP (1839,13+/-3691,55; R=432; p<0,01). The pre-dialysis cTnT was lower (0,0315+/-0,0372) as compared to the post-dialysis cTnT (average 0,0399). Euvolemic patients had BMI 24,28+/-3,15, as compared to the hypervolemic patients BMI 25,71+/-4,20 (p-n.s.). Increased BNP was not in correlation with older age (R-0,271 p-ns.) and duration of dialysis (R-0,198). The hematocrit level increases significantly during haemodialysis (39,9%; p<0,05). Patients with higher BNP and cTnT have significantly higher indexed left ventricular mass, as compared to the patients with normal ventricular function. Our study shows that 33,3% of asymptomatic patients on haemodialysis have elevated cTnT while all patients have elevated BNP. Measuring the plasma concentration of brain natriuretic hormones may be useful for identification of the dialysis patients with LVH.

GOAL: The patients with the chronical programm for haemodialisys have the higher risk from getting ill virus hepatitis C in the realtion to the rest population. AIM OF THE WORK: Was the evaluation of the prevalence and incidence of hepatitis C at the Center for Haemodialisys CCU Sarajevo and the effect of the prevalentive measures on the incidence of the serum conversion of hepatitis C, in the period from 2002 till 2004 year. MATERIAL AND METHOD: By the examening is comprehended 155 patients aged 54,58 +/- 14,797 years, with the aproximative length of the haemodialisys 58,9 +/- 53,9 months. Patients at the chronic programm of the bicarbonite haemodialisys taree times per week, and antibodies on the hepatitis C were determined III generation. Also was determined PCR. RESULTS: During the periiod of examination the dialized population was increased also 2002 year the prevalence of hepatitis C was 23,87% (37/155), in 2003 year 29,29% (46/157) and 2004 year the pregalence amounted 26,28% (46/175). Incidence of hepatitis C was significantly decreased in the course of the period of followup and in 2002 year was 16,21%, in 2003 year 13,04%, that in 2004 year would amount 4,34%, that is only in two patients occurred the serum conversion on hepatitis C. CONCLUSION: By applying of the corresponding protocoles and their strict realization (desinfection of the hands, wearing of gloves, apparatus desinfection) and separation of the dialyzed monitors for anti HCV positive and anti HCV negative patients dicreased significantly the hepatitis C incidence in our dialyzed population. The strict application of the preventive measures can completely prevent the speading occurrence of hepatitis C on haemodialisys.
