U Kliničkoj bolnici Dubrava u Zagrebu prvi je put u Hrvatskoj ugrađen novi sustav za krvožilni pristup kod bolesnika koji se liječi kroničnom hemodijalizom. Radi se o kombinaciji centralnoga venskog ...katetera i grafta engleskog naziva Hemodialysis Reliable Outflow (HeRO) device, skraćenog naziva HeRO-graft. Glavna je indikacija za primjenu ovoga krvožilnog pristupa okluzija ili značajna stenoza centralnih vena. Iz literature se doznaje da ovaj krvožilni pristup ima značajne prednosti u odnosu na tunelirani centralni venski kateter koji bi trebao biti zadnja opcija kod bolesnika koji zahtijevaju trajno nadomještanje izgubljene bubrežne funkcije. Za razliku od tuneliranih
katetera ovaj je sustav u potpunosti smješten potkožno, što ga čini otpornijim na infekcije. Do sada su u Kliničkoj bolnici Dubrava ugrađena dva HeRO-grafta za hemodijalizu i prema prvim iskustvima potrebna je detaljna obrada kandidata za ovu proceduru. Potrebno je dobro poznavati indikacije i kontraindikacije te je nužna suradnja više timova: nefrološkog, anesteziološkog, radiološkog i kirurškog. Osobito je potrebno obratiti pažnju na stanje arterijske cirkulacije okrajine koja se koristi za ovaj krvožilni pristup kako bi se izbjegle moguće ishemijske komplikacije. Kod obaju naših bolesnika postupak ugradnje protekao je uredno te smo započeli s korištenjem HeRO-grafta za potrebe hemodijalize.
Malnutrition, inflammation, and anemia are common in peritoneal dialysis (PD) patients. In this study, correlations between Malnutrition Inflammation Score (MIS), laboratory and anthropometric ...parameters, and anemia indices in Croatian PD patients were analyzed. One hundred and one PD patients (males/females 54/47, age 58.71 ± 14.68 years, mean PD duration 21.82 ± 21.71 months) were included. Clinical, laboratory, and anthropometric parameters were measured. Statistically significant correlations between MIS and erythropoietin weekly dose per kg of body weight (ESA weekly dose), hemoglobin (Hb), and erythrocytes were found (r = 0.439, p < 0.001; r = -0.032, p < 0.001; r = -0.435, p < 0.001), respectively. Also, statistically significant correlations were found between MIS and mean corpuscular volume (r = 0.344, p < 0.001), iron (r = -0.229, p = 0.021), and total iron binding capacity (TIBC) (r = -0.362, p < 0.001), respectively. Furthermore, statistically significant correlations between ESA weekly dose and serum albumin level and body mass index (BMI) were found (r = -0.272, p = 0.006; r = -0.269, p = 0.006), respectively. When we divided PD patients into 2 groups according Hb level (Hb ≥ 11 0 N = 60, 59.41 %) and Hb < 110 N = 41, 40.59%), statistically significant differences were found in MIS score (3.02 ± 2.54 vs 4.54 ± 3.54, p = 0.014), C-reactive protein (CRP) (3.52 ± 6.36 vs 7.85 ± 7.96, p = 0.005), and serum albumin level (44.22 ± 8.54 vs 39.94 ± 8.56, p = 0.003), respectively. Our findings suggest that anemia is correlated with malnutrition and inflammation in Croatian PD patients. Further studies are needed to assess whether modulating inflammatory or nutritional processes can improve anemia management in PD patients.

The Glycemic Index (GI) is a rating system that ranks carbohydrate-containing foods according to their postprandial blood glucose response relative to the same quantity of available carbohydrate of a ...standard such as white bread or glucose. The concept of GI was first introduced in the early 80's by Jenkins and coworkers. Since then, numerous trials have been undertaken, many indicating benefits of a low GI diet on glycemic control, as well as lipid profiles, insulin and C-peptide levels, inflammatory and thrombolytic factors, endothelial function and regulation of body weight. As a result, a low-GI diet may prevent or delay the vascular complications of diabetes. However, despite many studies supporting the benefits of the Glycemic Index as part of the treatment of diabetes mellitus, several areas of controversy have been raised in the literature and are addressed here. Clinicians treating diabetic patients should be aware of the potential benefits of low-GI foods in the prevention and treatment of diabetes and its complications.
Increased serum angiotensin-converting enzyme (SACE) activity and serum concentration of endothelin-1 (ET-1) were found in liver cirrhosis. We investigated a correlation between the different stages ...of liver fibrosis and SACE activity and serum ET-1 concentration. Seventy patients with pathohistologically established chronic liver disease were divided in three groups according to Ishak criteria for liver fibrosis: minimal fibrosis (Ishak score 0-1, n =20), medium fibrosis (Ishak score 2-5, n=20) and cirrhosis (Ishak score 6, n=30). SACE activity and ET-1 concentration were determined using commercial ELISA kits. SACE activity and ET-1 concentrations were proportional to the severity of disease, the highest being in patients with liver cirrhosis. Maximal increase in SACE activity was found between minimal and medium fibrosis while maximal increase in ET-1 concentration was revealed between medium fibrosis and cirrhosis. The analysis of the Receiver Operating Characteristic (ROC) curve for SACE activity suggested a cut-off value to separate minimal from medium fibrosis at 59.00 U/L (sensitivity 100%, specificity 64.7%). The cut-off value for serum ET-1 concentration to separate medium fibrosis from cirrhosis was 12.4 pg/mL (sensitivity 96.8%, specificity 94.4%). A positive correlation between SACE activity and ET-1 concentration was registered (Spearman's ñ = 0.438, p = 0.004). Both SACE activity and ET-1 concentration were increased in all stages of liver fibrosis. Cut-off points for SACE activity and ET-1 concentration could be a biochemical marker for the progression of fibrosis. Positive correlation between SACE activity and ET-1 concentration might indicate their interaction in the development of liver cirrhosis.
In this report, we presented a case of a patient with a rupturedabdominal aortic aneurysm (AAA) accompanied by pulmonaryembolism but without an aortocaval fistula, which has not beenreported so far.
Abstract
Background and Aims
Dialysis dependence and ESRD are known complications of ANCA associated vasculitis (AAV) with renal involvement. What is not so often discussed is the role of dialysis ...treatment at the time of diagnosis and how it affects patient outcomes as well as characteristics of such patients. We present data showing the importance of dialysis treatment at the time of diagnosis as the predictor of clinical outcomes.
Method
This study included 106 consecutive AAV patients with renal involvement in the period from 2007-2017. We performed renal biopsy on patients using automatic 16 Gauge needle. Light, immunofluorescent and electronic microscopy were performed.
Primary outcomes were combined outcome progression to end-stage renal disease, defined as persistent (more than three months) need for renal replacement therapy or permanent reduction of EGFR to <15ml/minute (according to CKD EPI formula) and/or death (ESRDD), death (D) and ESRD alone, and disease relapse. Kaplan Meyer survival analysis and multivariate Cox proportional hazard regression analysis were used to explore difference between phenotypes and finding significant predictors regarding outcomes.
Results
Out of 106 patients (55,6% female, median age 61; IQR 51-70) there were 66 (61,1%) microscopic poliangitiis (MPA), 20 (18,5%) granulomatosis with angitiis and 20 (18,5%) with renal limited vasculitis (RLV). Out of those 14 (13%) were PR3-ANCA positive patients, 57 (52,8%) MPO ANCA positive, 5 (4,6%) PR3-ANCA+MPO-ANCA positive and 32 (29,6%) ANCA negative patients. Average serum creatinine (SCr) levels was 316,5 μmol/l (IQR 207,0-548,5), 24-hour proteinuria median was 1,7g/24h (IQR 0,8-2,8). According to the Berden classification 43 (39,8%) patients had crescentic, 19 (17,6%) focal, 34 (31,5%) mixed and 12 (11,1%) sclerotic class. Follow up time ranged from 1 to 127 months. Median follow up time was 21 months (IQR = 7-44). Median time to diagnosis was 3 months (IQR 2,0-6,0). Patients requiring dialysis treatment at the time of diagnosis were more often MPO – (p=0,04), had more severe anemia (p=0,001), higher CRP (p=0,003), and more pronounced hypoalbuminemia (serums albumin <30g/l; p=0,006).Such patients were older than those not requiring dialysis (p=0,055) na had shorter time to diagnosis (p=0,001). Clinically such patient s presented more often with RPGN (p<0,001) which is in a way expected thus having higher SCr levels (p=<0,001). Histologically dialysis treated patients predominantly had crescentic class, while non-dialysis group had focal class (p<0,001). Of note dialysis group had more acute tubular damage (p=0,007). Interestingly enough there was slightly more positive C3 deposition in dialysis group (p=0,09). In univariate analysis the need for acute dialysis at the time of diagnosis of AAV was significant predictor for combined ESRDD, D, ESRD and relapse rate. In multivariate analysis the need for acute dialysis at the time of diagnosis of AAV remained significant predictor for ESRD (HR = 4,674, 95% CI =1,996-10,946; p = < 0,001) and relapse rate (HR = 59,545, 95% CI =3,467-1022,665; p = 0,005).
Conclusion
The need for dialysis at the time of AAV diagnosis is a strong predictor for ESRD and relapse rate. It is also interesting to further study differences between patients needing dialysis at the time of diagnosis and those who don’t need it.
Eighty samples of bronchoalveolar lavage fluid (BALF) were obtained from the total of 48 patients (22 females and 26 males) and analyzed. Eighteen of those patients were organ transplant recipients. ...The relationship between polymorphonuclear leukocyte (PMN) count in direct sample and semi quantitative Gram-positive and Gram-negative bacterial content were analyzed in BALF samples. PMN count in direct sample and Gram-positive and Gram-negative bacterial content of the final microbiological report was compared as well. On the total number of samples PMN count in direct samples of BALF was statistically significant regarding the presence of Gram-positive bacteria in the same sample; it was nearly significant regarding the presence of Gram-negative bacteria; and it was statistically significant for the total bacterial content. If BALF samples are divided into those obtained from organ-transplant and those obtained from non-organ-transplant patients, positive, statistically significant relationship is found in the organ-transplant group, more specifically for the relationship between PMNs and total bacterial content. When PMN count in direct microbiological sample was compared with the results of the final microbiological report, statistically significant relationship was found neither with respect to all BALF samples, nor after dividing them into "organ-transplant" and "non-organ-transplant" group. We did not find differences caused by gender.
