ABSTRACT

BACKGROUND: Infection is a major cause of morbidity and mortality in intensive care units (ICUs) worldwide. Local epidemiological studies need to be conducted to set the priorities for surveillance and prevention programmes. AIM: To investigate the epidemiology of hospital-acquired infections (HAIs) among patients admitted to Polish adult ICUs over a three-year period. METHODS: Data were collected according to the European Centre for Disease Prevention and Control (ECDC) European Union Point Prevalence Survey of Healthcare-associated Infections and Antimicrobial Use in European Acute Care Hospitals (EU-PPS HAI & AU) protocol for 39,318 patients within 160 acute care hospitals. From this initial database, data for adult ICU patients (N=945) were filtered for further analyses. FINDINGS: HAIs were present in 370 patients (39%) and 430 HAI episodes were recorded. The most common HAIs were respiratory tract infections (45%), usually caused by Enterobacteriaceae and Gram-negative non-fermenters. The majority (87%) of these infections were likely to be device associated. Out of 61 cases of bloodstream infection, 51% were catheter associated. These bloodstream infections were mainly caused by coagulase-negative staphylococci. Among 57 cases of surgical site infection, 42% were classified as organ/space, 33% were classified as deep incisional, and 25% were classified as superficial. The predominant micro-organisms were Enterobacteriaceae and Staphylococcus aureus. Out of 50 cases of urinary tract infection, 96% were device associated. CONCLUSIONS: The prevalence of HAI among Polish adult ICU patients is higher than described in similar studies, but may be partially affected by methodological differences. The proportion of device-associated infections was very high, so there is an urgent need to introduce countrywide, targeted surveillance and prevention programmes.

ABSTRACT

BACKGROUND: The autonomic nervous system plays an important role in heart function regulation. One of the most acknowledged methods for noninvasive measurement of autonomic system activity is to determine heart rate variability (HRV). Reduced HRV parameters-heart rate rigidity/stiffness-are an independent prognostic factor of sudden cardiac death risk because of arrhythmia. Renal transplantation is an important factor in HRV changes because of hemodynamic and ion disturbances. The main purpose of this study was to determine the influence of HRV disturbances during renal transplantation procedures on long-term mortality in patients with chronic kidney disease. METHODS: A prospective observation study was performed in the Department of Anesthesiology, Intensive Care, and Acute Poisoning, Pomeranian Medical University, Szczecin, Poland. There were 75 patients (mean age, 47 ± 12 years; 42 men) treated with renal transplantation between 2008 and 2010. Patients were monitored with electrocardiographic tracing with the use of 7 electrodes in position type B. The final stage of analysis was to determine the possible relationship between HRV parameters during the perioperative period and the number of deaths within a 5-year follow-up. RESULTS: HRV parameters during the perioperative period of renal transplantation and the number of deaths within a 5-year follow-up, measured by use of the Holter method, did not differ among patients in the studied population. CONCLUSIONS: HRV is a noninvasive and confirmed tool used for the evaluation of autonomic function and mortality risk in patients with end-stage renal disease. HRV parameters recorded in the perioperative period are not optimal stratification tools for estimating the risk of cardiac deaths in patients with end-stage renal disease.

ABSTRACT

BACKGROUND: The quality of transplanted organ and timing of the initiation of its effective function depends on many factors potentially causing graft dysfunction. The aim of this study was to evaluate the influence of the cardiovascular status of multiorgan donors on the long-term kidney graft survival over a 15-year observation period. METHODS: In 2007, the authors of this study published a multicenter prospective study evaluating the influence of the hemodynamic status of multiorgan donors on the early function of transplanted kidney. The results of that study showed that mean arterial pressure, central venous pressure, and pulmonary capillary wedge pressure values of the donor importantly influence the frequency of delayed graft function after renal transplantation. The present analysis covers the effect of the donor's hemodynamic status parameters on graft function time within the 15-year observation period. Univariate and multivariate analyses using the Cox regression proportional hazard model were performed to evaluate the prognostic parameters for overall survival and renal graft survival time. P < .05 was considered to be significant. RESULTS: The univariate analysis showed a significantly shorter time of graft survival in the group of recipients who had a kidney retrieved from donors with lower pulmonary capillary wedge pressure values (P = .038) and lower cardiac index values (P = .039). The same results were obtained for the multifactorial Cox logistic regression analysis. CONCLUSIONS: The filling of the intravascular bed of the donor as determined by pulmonary capillary wedge pressure and maintained donor tissue perfusion as determined by cardiac index, impose important factors influencing long-term kidney graft survival.

ABSTRACT

BACKGROUND: Long-term function of transplanted kidney is the factor determining quality of life for transplant recipients. The aim of this study was to evaluate the effect of selected factors on time of graft function after renal transplantation within 15 years of observation. METHODS: Preoperative and intraoperative factors were analyzed in 232 kidney recipients within a 15-year observation period. Analysis included age, sex, cause of recipient's renal failure, length of hemodialyses before transplantation, peak panel reactive antibodies test, human leukocyte antigen compatibility, cold ischemia time, delayed graft function occurrence, length and time of hemodialyses after transplantation, early graft rejection, creatinine level at days 1, 3, 7, 30, 90, and 180 after transplantation, and influence of these factors on the time of graft function. Statistical analysis was performed with the use of univariate and multivariate Kaplan-Meier test and Cox regression proportional hazards model, with P < .05 considered to be significant. RESULTS: Univariate analysis showed significantly shorter renal graft function in the group of recipients with higher creatinine levels in all of the analyzed time periods and in patients experiencing delayed graft function. Length of time of hemodialyses after transplantation and number of dialyses had significant impact on worsening of late transplant results. Multivariate analysis reported that early graft rejection in the postoperative period is an independent factor improving late graft function: P = .002; hazard ratio (HR), 0.49 (95% confidence interval [CI], 0.31-0.78). Higher creatinine level at day 90 after kidney transplantation is a predictive factor of late graft dysfunction: P = .002; HR, 1.68 (95% CI 1.2-2.35). CONCLUSIONS: Creatinine level at day 90 after renal transplantation is the prognostic factor of long-term kidney function. Early transplant rejection leads to introduction of more aggressive immunosuppression protocol, which improves long-term transplant results.

ABSTRACT

BACKGROUND: Despite dynamic development within the field of transplantology, the immunization of a potential organ recipient remains an important issue for transplant teams. Panel reactive antibodies (PRA) identification in the serum of the recipient remains routine practice in the majority of transplantation centers. The influence of peak PRA levels on graft function is a well known fact. The aim of this study was to determine the effect of peak PRA on long-term survival after renal transplantation. METHODS: The study was conducted on a group of 232 kidney recipients from multiorgan donors, transplanted in 6 transplant centers in Poland from 1995 to 1997. Data analyzed in this study included recipients' age, sex, PRA, HLA, number and time of hemodialyses after the transplantation, cold ischemia time, and etiology of end-stage renal disease. The effect of data examined in this study on mortality was evaluated at set time points at 5, 10, and 15 years after transplantation. The statistical methods included monofactorial and multifactorial Kaplan-Meier survival analysis and Cox proportional hazards model for mortality prediction. A P value of <.05 was considered to be statistically significant. RESULTS: Among all of the analyzed factors, only peak PRA concentrations significantly correlated with increased mortality among renal transplant recipients. The results were analyzed in all of the set time points: P = .007 at 5 years, P = .014 at 10 years, and P = .05 at 15 years after transplantation. CONCLUSIONS: The increased level of PRA in kidney recipients is a risk factor increasing mortality after the transplantation.

ABSTRACT

BACKGROUND: Patients undergoing transplantation procedures are at a high risk of developing infections because of the need for immunosuppression. Infections presenting directly after renal transplantation greatly influence the overall success of the procedure. The aim of this study was to evaluate the influence of postoperative infection on the length of survival after renal transplant. METHODS: In 2009 a multicenter prospective trial evaluating the factors that influence the occurrence of postoperative infective complications was published by the authors. That study reported that 25 out of 232 recipients of a renal transplant were diagnosed with an infection. The present study shows the effect of postoperative infection on the length of survival after renal transplantation during a 15-year observation period. Statistical methods involved monofactorial and multifactorial Kaplan-Meier analysis for the length of survival and the Cox proportional hazards model for mortality prediction. A P value of <.05 was considered to indicate statistical significance. RESULTS: The analysis demonstrated that the lifespan of renal transplant recipients was decreased in those with postoperative infection, at both year 10 of the observation period (P = .013) and 15 years after transplantation (P = .012). Moreover, it was ascertained that an infection in the postoperative period was an independent risk factor increasing the mortality after renal transplantation: P = .026; hazard ratio 2.90 (95% confidence interval, 1.13-7.41). CONCLUSIONS: The occurrence of an infection in the postoperative period significantly decreases the lifespan of a renal transplantation recipient.

ABSTRACT

BACKGROUND: Inflammatory mediators play an important role in kidney graft outcome. The cytokine and chemokine gene polymorphisms are associated with variable production, activity, expression, or ligand-receptor affinity. Genetic variation in the DNA sequence of the interleukin 12B (IL12B), interleukin 16 (IL16), and interleukin 18 (IL18) genes may lead to altered cytokine production and activity. These variations can lead to changes in individual patient outcomes after kidney transplantation. It is known that polymorphisms of interleukins have an influence on inflammatory diseases, eg, Crohn's disease, diabetes, and asthma. AIM: The aim of this study was to evaluate the correlation between IL12B, IL16, and IL18 gene polymorphisms with delayed graft function (DGF), acute rejection episodes (AR), and chronic rejection episodes (CR). MATERIALS AND METHODS: A total of 267 (38.6% women, 61.4% men) recipients were included in the study. Cadaveric kidney transplantations were performed at the Department of General Surgery and Transplantation. Polymerase chain reaction was used to determine gene polymorphisms of IL12B (rs3212227), IL16 (4778889), and IL18 (rs1946518, rs187238) in 2 mL of serum. Statistical significance (P < .05) was analyzed by logit regression, ANOVA and odds ratio (OR) of χ(2) with Yates correction (95% confidence interval). RESULTS: Regression analysis revealed no significance between AR/DGF/CR and IL-2B, IL16, IL18rs1946518, and IL18-rs187238 (P > .05). The CR group, AA vs CC genotype of IL18 (rs1946518), had an OR = 2.35 (P = .04). AR and DGF groups had no significance in OR. CONCLUSIONS: There was no statistical significance between IL12B, IL16, and IL18 (rs187238) gene polymorphisms and kidney graft outcome after transplantation. Presence of AA genotype (IL18-rs1946518) is connected with a 2.35 times higher risk of CR occurrence.

ABSTRACT

BACKGROUND: Organ donors can be generally divided into two groups according to the cause of their death. The first group is composed of those who died because of physical injuries, especially road traffic injury, and the second group, those who died from central nervous system (CNS) stroke or bleeding. The aim of our work was to examine hemostatic processes among kidney donors. MATERIALS AND METHODS: The 38 deceased kidney donors (KD) included 11 women and 27 men of overall average age of 37±12 years. The donor group of according to the cause of death, included 14 injured donors (ID) (41%) and 24 noninjured donors (ND) donors (59%). The control group consisted of 25 healthy volunteers matched for sex and age. We determined the following concentrations: antithrombin (AT), thrombin/antithrombin complexes (TAT), and prothrombin F1+2 fragments. The fibrinolytic parameter concentrations were: plasminogen (PL), plasmin/antiplasmin complexes (PAP), and D-dimers. RESULTS: Deceased kidney donors showed an increased plasma concentrations of TAT complexes (P<.000001) and prothrombin fragments F1+2 (P<.0000001); however, the protein C concentration was decreased (P<.000001). The antithrombin activity was similar to the control group. The concentrations of PAP complexes and d-dimers were higher (both P<.000001), but the level of PL lower among KD compared with controls (P<.0000001). The higher of TAT, PAP complexes, d-dimers, and F1+2 concentrations as well and as lower plasminogen and PC concentrations were evidence for increased activation of blood coagulation and fibrinolysis in cadaveric KD. However, analysis compairing ID versus ND donors revealed increased concentrations of PAP complexes (P<.05) and decreased amounts of TAT complexes (P<.01) among ID subgroup. The positive predictive value (PPV) and negative (NPV) for PAP complexes were 75% and 68% and for TAT, 71% and 57%, respectively. On the basis of these observations, we concluded that an intensive activation of fibrinolytic process occurs among the ID. In contrast, ND show intensive activation of blood coagulation.

ABSTRACT

BACKGROUND: We sought to determine the risk factors influencing the occurrence of early graft loss among kidney transplant recipients. STUDY DESIGN: One hundred forty-six potential donors and 230 kidney recipients were included in the study. Prior to organ procurement we collected demographic data as well as hemodynamic data of mean arterial pressure, central venous pressure, pulmonary capillary wedge pressure, systemic vascular resistance index acquired by means of a thermodilution method. The recipient data included age, gender, prior hemodialysis period, panel-reactive antibodies, cold ischemia time, renal insufficiency cause, and donor-recipient gender mismatch. We assessed the influence of the data on graft loss at 30 days after renal transplantation. To confirm the relationships, we performed statistical analyses using chi-square, Fisher exact, and V. Cramer tests. RESULTS: There were no significant relationships between the analyzed parameters and early graft loss in the study group except for gender mismatch. The 71 female recipients of male kidneys showed the lowest graft survival: donor/recipient male/female 89%; donor/recipient female/male 97%; no mismatch 97% (P=.01). CONCLUSIONS: Female recipients of male kidneys may experience a greater risk of early graft loss compared with all other gender combinations.

ABSTRACT

BACKGROUND: The mechanisms of sudden cardiac death are difficult to recognize, but repolarization disturbances have been shown to be the cause. The purpose of this study was to investigate whether the polymorphism of nitric oxide synthase 1 adaptor protein (NOS1AP) was related to the risk of occurrence of corrected QTc-interval prolongation and ventricular arrhythmias recorded on electrocardiography (ECG) Holter monitoring in kidney transplant recipients. STUDY DESIGN: The 75 adult first kidney transplant patients included 43 men with an overall mean age of 45±12 years (range, 20-68). Additional patient monitoring during the procedure and in the postoperative period consisted of a continuous ECG tracing recording and investigation of the rs10918594 NOS1AP polymorphism. RESULTS: We observed Transient QTc-interval prolongation during the perioperative period. NOS1AP genotypes were in Hardy-Weinberg equilibrium. For further statistical analysis, we combined GG homozygotes and CG heterozygotes because of the small numbers available; therefore, only a dominant mode of inheritance was investigated. There were no gender differences in QTc-interval patterns. Analysis of variance with repeated measures revealed no interaction between NOS1AP and QTc-interval values taken at various times among the kidney recipients. CONCLUSIONS: The transplantation procedure may lead to dynamic repolarization disturbances, which may produce an increased risk of severe arrhythmias despite optimization of patient status. The NOS1AP rs203462 polymorphisms did not correlate with an increased risk of QT interval prolongation among kidney recipients.

ABSTRACT

INTRODUCTION: Following kidney transplantation, septic complications are the leading causes of therapeutic failure including recipient death or graft removal. The serum creatinine level is one of the earliest metrics of kidney metabolic function. We examined the influence of graft infection on serum creatinine levels in kidney recipients. STUDY DESIGN: We analyzed the function of 220 kidneys transplanted in nine centers in Poland. The kidneys were recovered from 146 multiorgan donors. Donor urea and creatinine levels were within the normal range. We investigated the influence of perioperative graft infection incidence on recipient creatinine levels at 1, 2, 3, 7, 14, 30, 90, and 180 days after kidney transplantation. The association of the serum creatinine level with categorical variables was assessed using either Student t test analysis of variance and multivariate techniques. In all analyses P<.05 indicated statistical significance. RESULTS: There were 25 graft infections revealing a significant relationship with increased recipient serum creatinine level after kidney transplantation (P=.003). Multivariate analysis confirmed the impact of infection. CONCLUSION: Perioperative kidney graft infection influenced graft funtion in the early and late periods post-transplantation.

ABSTRACT

BACKGROUND: The etiopathogenesis of lymphoceles remains incompletely understood. The aim of our work was to analyze the perturbations of blood coagulation process for their possible impact on the etiology of lymphoceles. Additionally we performed an evaluation of the incidence and effectiveness of treatment methods for lymphoceles. MATERIALS AND METHODS: During 2004 to 2010, we performed 242 kidney transplantations in 92 female and 150 male patients. The hemostatic parameters included concentrations of: antithrombin, plasminogen, thrombin/antithrombin complexes (TAT), prothrombin products F1+2 (F1+2), d-dimers, and plasmin/antiplasmin complexes. RESULTS: At 7 years follow-up 27 (11%) recipients had developed symptomatic lymphoceles, namely abdominal discomfort, a palpable mess in the lower abdomen, arterial hypertension, infection of the operative site with fever, lymphorrhoea with surgical wound dehiscence, decreased diurnal urine output with an elevated plasma creatinine, voiding problems of urgency and vesical tenesmus, and/or symptoms of deep vein thrombosis. We applied the following methods of treatment aspiration alone, percutaneous drainage, laparoscopic fenestration or open surgery. In two only patients did perform open surgery. Since 2008 we have not performed an aspiration alone because of high rate of recurrence (almost 100%) and abandoned open surgery in favor of a laparoscopic approach. Our minimally invasive surgery includes percutaneous drainage guided by ultrasound and a laparoscopic procedure with 100% effectiveness. The examined hemostatic parameters revealed decreased concentrations of TAT complexes and F1+2 in subjects with lymphocele showing positive predictive values of 33% and 41% respectively. The negative predictive values for TAT complexes and F1+2 were 14% and 10%, respectively, suggesting decreased blood coagulation activity among effected recipients. Altered blood coagulation processes may explain some aspects of the disturbances of postoperative obliteration of damaged lymphatic vessels and formation of pathological lymph collection afterward. CONCLUSIONS: Perturbations of blood coagulation may be one cause for a lymphocele.

ABSTRACT

INTRODUCTION: According to Polish brain death (BD) criteria, instrumental confirmatory tests should be used in certain clinical situations, particularly any case for which clinical examinations seem inadequate. Electrophysiological tests are often unavailable. Therefore, cerebral perfusion testing is the method of choice with four-vessel digital subtraction angiography (DSA), the gold standard. Unfortunately, DSA is an expensive and invasive examination that requires an experienced neuroradiologist and the availability of an angiography suite. Recently, multirow computed tomographic devices became available, even in smaller hospitals in Poland. Despite this fact, computed tomographic angiography (CTA) and computed tomographic perfusion (CTP) are not accepted in BD diagnosis protocols in Poland because of limited experience and a lack of widely accepted criteria. In this situation, we started a multicenter trial to determine the accuracy of CTA and CTP to confirm BD. METHODS: We examined 24 patients who fulfilled standard clinical BD criteria. We recognized the absence of brain perfusion in CTA examination following the criteria proposed by the French Society of Neuroradiology, namely, the absence of opacification of M4 middle cerebral artery segments (M4-MCA) and of deep cerebral veins. RESULTS: In all of our patients, CTA showed absence of opacification of M4 segments and of deep cerebral veins. In addition, three patients had CTA showing weak opacification of A2 segments of the anterior cerebral artery (A2-ACA) and M2 or M3-MCA. Opacification of the basilar artery or of the posterior cerebral arteries was not noted in any case. In all patients, CTP revealed zero values of regional cerebral blood volume and regional cerebral blood flow. Conventional angiography confirmed cerebral circulatory arrest in all 24 cases. CONCLUSION: CTA and CTP seem to be promising radiological examinations for the diagnosis of BD. They may be noninvasive alternatives to conventional cerebral angiography, and to the other instrumental confirmatory tests, that are unavailable or inadequate.

ABSTRACT

BACKGROUND: Many factors affect long-term results in kidney transplantation including histologic damage as a independent predictor, eg, chronic allograft dysfunction (CAD) in protocol biopsies and age-dependent lesions. Histopathologic findings correlate with the incidence of delayed graft function, eventual renal function, and allograft survival, allowing a rather precise prediction of graft outcomes. PATIENTS AND METHODS: We analyzed 92 thick-needle preimplantation renal biopsies and 29 from grafts after explantation. They had been preserved in 4% formalin and immersed in paraffin. Evaluable specimens contained ≥10 glomeruli and ≥2 arterial cross-sections. We analyzed tubulitis, intensity of acute tubular necrosis (ATN), inflammatory infiltration, glomerulonephritis, arterial hyalinization, arteritis, fibrosis, tubular atrophy, arterial intimal fibrosis, increased mesangial matrix, and glomerulosclerosis percentage, although for comparative analysis not only optimal ones were taken into consideration. Over postoperative time, we analyzed patient condition, urine output, serum concentrations of creatinine, urea, uric acid, and ions as well as necessity for postoperative dialysis, ie, delayed graft function (DGF). During the 3-year observation we analyzed living recipients, graft loss, death with a functioning graft, incidence of dysfunction (CAD), and acute rejection episodes (ARE). RESULTS: We observed significant correlations between immediate graft function (IGF) and lack of ATN in the pretransplantation biopsy. The presence of ATN significantly correlated with DGF and primary graft non-function. There was no correlation between renal function and arterial hyalinization or fibrosis, inflammatory infiltration, and tubular atrophy. Over postoperative time we observed significant correlations between IGF and the lack of interstitial fibrosis as well as significantly lower levels of creatinine, urea, and potassium as well as greater urine output early after transplantation. IGF correlated with shorter time to reach a creatinine level of 2 mg/dL, lower concentrations of creatinine, urea, and potassium, as well as greater diuresis during the first 5 days. In addition, lower creatinine and urea concentrations after 1 month and of urea at 6 and 36 months were associated with IGF. Female recipients showed lower concentration of creatinine over 3 months, of urea during the 1st day, and of potassium at 1 month; however, thereafter the differences were not significant. Better function of the right kidney was observed. The presence of severe ATN (ATN III) correlated with lower creatinine concentrations at 6 months and urea after 3 years. The presence of hyalinization in biopsies correlated with higher concentrations of urea at 1 year and of borderline significance after 3 years; surprisingly, potassium concentrations were lower after 2 and 3 years. The presence of inflammatory infiltrates correlated with higher creatinine concentrations after 1 and 3 years; similar correlations, albeit of borderline significance, were observed in tubular atrophy. Interstitial fibrosis correlated with creatinine concentrations during 10 days after the operation and after 12 months, also with potassium concentrations 5 days after the operation. Borderline correlations were observed between donor age and creatinine concentration in the first day after the operation, after 6 months, and time to achieve a creatinine concentration of 2 mg/dL. We observed that biopsies with greater numbers of glomeruli correlated with better graft function, namely, lower creatinine concentrations after 5 days as well as at 1 and 6 months, as well as lower urea concentrations after 5 days and 6 months. We also observed differences in renal function depending on gender. The presence of acute tubular necrosis, arterial fibrosis and a lack of inflammatory infiltration in pretransplantation biopsy correlated with worse late renal function. Explantation biopsies showed signs of CAD in 66.4% and histologic features of ARE in 38.51%.

ABSTRACT

Polish brain-death criteria, similar to the original Harvard criteria, were published in 1984. In 1990, they were converted to brainstem death criteria, and were revised twice, in 1994 and in 1996. However, they could not be used in many complicated clinical situations such as intoxication, metabolic alterations, major facial injury, infratentorial lesions, and cervical spinal cord injury. The new Polish Transplant Act, passed by the Polish Parliament in 2005, recommends implementation of criteria for whole-brain death for brain-death diagnosis. In 2007, the Polish Ministry of Health Commission outlined new Polish brain-death criteria. Optional use of instrumental confirmatory tests was implemented in the new Polish national code of practice for the diagnosis of brain death in adults. In children up to age 2 years, instrumental tests are obligatory. Initially, there were problems in understanding the new, slightly more complicated classifications of primary and secondary brain injuries, infratentorial and supratentorial processes, modified apnea test. A broad commentary that addressed the most frequently asked questions was published in Anesthesiology and Intensive Therapy, the official journal of the Polish Society of Anaesthesiology and Intensive Therapy. This article dealt with most of the problems associated with implementation of the new criteria for diagnosis of brain death.

ABSTRACT

BACKGROUND: Brain death is an important variable contributing to donor-specific kidney damage. Poor kidney performance posttransplantation may be related to the cause of death of the donor. OBJECTIVE: To assess the influence of cause of death in multiorgan donors on the function of transplanted kidneys. MATERIAL AND METHODS: Standard criteria for the brain stem death protocol were applied in 146 potential heart donors included in the study. Conventional supportive management consisted of mechanical ventilation to achieve normocapnia, rewarming, and fluid and electrolyte replacement. Dopamine infusion not exceeding 10 microg/kg/min and desaminovasopressin were titrated to predetermined mean arterial pressure (MAP). In renal allograft recipients (n = 232), kidney function was monitored using serial serum creatinine concentrations on days 1, 2, 3, 7, 14, 30, and 90 posttransplantation. The relation between donor cause of death (injury, bleeding, or other cause) and recipient serum creatinine concentration was analyzed in the postoperative period. RESULTS: Significantly greater serum creatinine concentrations were observed up to 14 days posttransplantation in recipients of a kidney from a donor who died of any cause other than injury. Recipients of a kidney from a donor who died of bleeding exhibited significantly greater serum creatinine concentrations at 30 days posttransplantation. CONCLUSIONS: A cause of death other than injury or bleeding in a multiorgan donor is predictive of worse kidney graft function in the first 14 days posttransplantation. Intracranial bleeding in a multiorgan donor is predictive of worse kidney graft function in the early period posttransplantation.

ABSTRACT

INTRODUCTION: The purpose of this study was to investigate whether the polymorphism in the kinase-binding domain of A-kinase anchoring protein 10 (AKAP10) was related to the risk of occurrence of potentially dangerous arrhythmias during kidney transplant. METHODS: We performed this prospective observational study with additional patient monitoring during the kidney transplant procedure and in the postoperative period with continuous electrocardiogram (ECG) - (digital holter; ECG monitor type 300-7 Suprima system; Oxford, UK). After manual trace analysis, we performed classification of arrhythmias by interval measurement (including QT correction according to Bazett's formula: Qtc = QT/RR1/2), ST segment analysis within all channels, and analysis of heart rate variability (HRV) parameters (time analysis: SDNN as total rate variability measure, SDANN as long-term variability measure, SDNNindex, rMSSD and pNN50 as short-term variability measure) as well as frequency measure of power width parameters in the spectrum between 0.0033 Hz and 0.4 Hz. Subsequently applying polymerase chain reaction restriction fragment length polymorphism methods, we investigated A1936G (rs203462) AKAP10 polymorphism among 54 kidney recipients. RESULTS: Analysis of variance showed that prolongation of the QTc interval associated with the variant genotypes (GG + AG) was significantly greater compared with the AA genotype among kidney recipients (P = .04). We did not observe a relationship between the AKAP10 polymorphism and other arrhythmias, or clinical or environmental factors. CONCLUSIONS: Our data suggested that the AKAP10 (rs203462) GG + AG variation was associated with an increased risk of severe arrhythmias during kidney transplantation.

ABSTRACT

INTRODUCTION: Septic complications following kidney transplantation are a leading cause of therapeutic failure. An early diagnosis may protect the recipient from the severe consequences of sepsis. We sought to determine the risk factors influencing the occurrence of septic complications among kidney transplant recipients. MATERIALS AND METHODS: The 146 potential donors included in the study were evaluated for brain stem death criteria. Supportive management included mechanical ventilation to normocapnia, rewarming, as well as fluid and electrolyte replacement. Dopamine infusions and desaminovasopressin were titrated to predetermined mean arterial pressure (MAP). Central venous pressure (CVP) was maintained at 8 to 11 mm Hg. Hemodynamic data were acquired by the thermodilution method prior to organ procurement: MAP, CVP, pulmonary capillary wedge pressure (PCWP), and systemic vascular resistance index (SVRI). Recipient data included age, gender, period of prior hemodialysis, panel reactive antibodies, cold ischemia time, and cause of renal insufficiency. The 232 kidney recipients were examined for occurrence of septic complications including septicemia, pneumonia, peritonitis, or graft infection. RESULTS: Kidney transplants from donors with MAP < 70 mm Hg and SVRI < 1200 dyne x s/cm(5) x m(2) showed a significantly higher occurrence of septic complications in recipients (P < .05) where mortality rate was also significantly greater (P < .01). CONCLUSIONS: MAP < 70 mm Hg and SVRI < 1200 dyne x s/cm(5) x m(2) among organ donors predicted greater occurrence of septic complications and increased mortality among kidney transplant recipients.

ABSTRACT

BACKGROUND: One common complication after kidney transplantation is a lymphocele. The aim of our work was an analysis of incidence of lymphocele and the effectiveness of minimal invasive methods in the management of this complication. MATERIALS AND METHODS: The examined group was consisted of 158 patients (68 female and 90 male) with end-stage renal disease who underwent kidney transplantation. RESULTS: Twenty-one patients (13%) developed symptoms of lymphocele after transplantation procedure within an average time of 34 weeks. The clinical symptoms included a decrease in 24-hour urine collection, an increase in plasma creatinine concentration, abdominal discomfort, lymphorrhea with a surgical wound dehiscence, voiding problems of urgency or vesical tenesmus, febrile states, or symptoms of deep vein thrombosis. The following methods were applied with variable efficacy: aspiration with recurrence 75%; percutaneous drainage with 55%, effectiveness; laparoscopic fenestration with 72% satisfactory outcomes (1 patient presented an excessive bleeding after the procedure), and classic surgery with favorable results. CONCLUSION: Percutaneous drainage guided by ultrasonic imaging should be recommended as the first attempt to cure a lymphocele. Laparoscopy is a feasible, safe technique that should be used after unsuccessful percutaneous drainage. A larger series of patients is required to confirm the superiority of minimal invasive methods to the classical approach.

ABSTRACT

Efficient urine production after kidney transplantation is often evidence of good graft function. If severe organ injury occurs, we have oliguria or anuria and the patient requires postoperative hemodialysis. In most cases, graft function recovers after a few hemodialysis treatments-delayed graft function (DGF). Therefore, recognition of factors influencing the onset of DGF is crucial. We examined the state of the circulatory system by a thermodilution method in 101 organ donors, taking into account mean arterial pressure (MAP), central venous pressure (CVP), pulmonary capillary wedge pressure (PCWP), systemic vascular resistance index. We also examined 232 kidney recipients, based on age, gender, panel-reactive antibody, cold ischemia time, and reason for renal insufficiency. We defined DGF as at least one hemodialysis after kidney transplantation. In logistic regression analysis, we showed that donor MAP, CVP, and PCWP of the substantially influenced the occurrence of DGF among kidney transplant recipients. Maintaining an adequate MAP and a sufficient volume in the donor circulatory system substantially decreased the occurrence of DGF after kidney transplantation.
