Update on the Management of Urological Problems Following Kidney Transplantation.

Urological problems in kidney transplant recipients are not limited only to posttransplantation urological complications. These problems are a cause of significant patient mortality and morbidity that have wide-ranging effects on graft survival throughout the entire life of the graft. Ultimately, the transplant comprises a major portion of the urinary system; therefore, the transplant team should be prepared for foreseeable and unforeseeable urological problems in the short and long terms. These mainly include postoperative urological complications (urine leakage, ureteral stenosis, and vesicoureteral reflux), bladder outlet obstruction, and graft urolithiasis. In recent years, significant advances have been made in the management of urological complications, especially due to advances in endourologic interventions. The aim of this review is to summarize the management of urological problems after kidney transplantation in the context of the current literature.

Laparoscopic Live Donor Nephrectomy: Experience of High-Volume Center with 2,477 Cases.

OBJECTIVE: Donors' health and safety are mandatory in the living-donor kidney transplantation procedure. Laparoscopic live donor nephrectomy (LLDN) provides an increase in donor numbers with its benefits and becomes a standard of care. We aimed to explain the results, complication rates, tips, and tricks of the largest number of LLDN case series ever performed in the literature. MATERIALS AND METHODS: Between August 2012 and December 2019, 2,477 live donor case files were analyzed retrospectively. Age, gender, hospitalization times, body mass index, warm ischemia times, operation times, numbers of arteries, side of the kidneys, and complications were noted. RESULTS: 1,421 (57.4%) of 2,477 donors were female (p = 0.007). Operation times and warm ischemia times were found longer in right-sided LLDN and donors with multiple renal arteries (p = 0.046, <0.001, and <0.001, respectively). Obesity (BMI >30 kg/m2) did not affect warm ischemia times while prolonging the operation times (p = 0.013). Hospitalization times and numbers of complications were higher in obese donors. CONCLUSIONS: LLDN seems to be a reliable solution with fewer complications and higher satisfaction rates. We hope to illuminate the way with tips and trick points for beginner transplant surgeons based on the experience obtained from 2,477 LLDN cases.

Retrospective analysis of clinical data and treatment of primary focal segmental glomerulosclerosis patients / Análisis retrospectivo de datos clínicos y tratamiento de pacientes con glomeruloesclerosis segmentaria focalprimaria

Abstract Introduction: The aim of the study is to compare clinical data of primary focal segmental glomerulosclerosis patients with other data in the literature. In addition, initial immunosuppressive therapy (steroid, calcineurin inhibitors) responses are aimed to be compared with the results in the literature. Methods: Forty seven patients, who were followed up for at least 12 months with primary focal segmental glomerulosclerosis as a result of kidney biopsy. Results of biochemical tests and treatment modalities were evaluated. Results: The mean age of the 47 patients with primary focal segmental glomerulosclerosis was 45.68 (± 13.92). Twenty-one (44.6 %) of 47 patients had anangiotensin converting enzyme inhibitor / angiotensin receptor blocker, 7 (14.8 %) had only corticosteroids, and 6 (12. 7%) had calcineurin inhibitor + low-dose corticosteroids treatment. Thirteen patients (27.6 %) used calcineurin inhibitor + low-dose corticosteroids after receiving corticosteroids treatment. The patients who received corticosteroids or calcineurin inhibitor + low-dose corticosteroids treatment as the initial treatment were compared at the 0, 6 and 12 months of treatment in terms of laboratory and clinical features. At the end of the first year, 4 out of 6 (66 %) patients with low-dose corticosteroids and calcineurin inhibitor and 6 out of (86 %) of 7 patients with corticosteroids had remission (p>0.05). Conclusion: We found the initial steroid treatment and calcineurin inhibitor treatment to be equally effective. We thought that patients with steroid intolerance could be given calcineurin inhibitor in the first step, but if the cost is considered, the first option, such as The Kidney Disease Improving Global Outcomes recommendation, was again steroid.

Resumen Introducción:El objetivo del estudio es comparar los datos clínicos de pacientes con glomeruloesclerosis segmentaria focal primaria con otros datos de la bibliografía. Asimismo, se busca comparar las respuestas de la terapia inmunosupresora inicial (esteroides, inhibidores de la calcineurina) con los resultados en las publicaciones citadas. Material y métodos: Se incluyeron 47 pacientes con glomeruloesclerosis segmentaria focal primaria como resultado de una biopsia renal, y cuyo seguimiento duró, al menos, 12 meses. Se evaluaron los resultados de las pruebas bioquímicas y las modalidades de tratamiento. Resultados: La edad media de los 47 pacientes con glomeruloesclerosis segmentaria focal primaria fue de 45,68 (± 13,92). 21 (44,6 %) del total de los pacientes tenían un inhibidor de la enzima convertidora de la angiotensina / bloqueante del receptor de la angiotensina. Siete pacientes (14,8 %) solo tenían corticosteroides y 6 (12,7 %) tenían un inhibidor de la calcineurina + un tratamiento con esteroides en dosis bajas. Se aplicóinhibidores de la calcineurina + dosis bajas de corticoesteroides en13 pacientes (27,6 %) después de recibir tratamiento con ciclosporina. Los pacientes que recibieron ciclosporina o inhibidores de la calcineurina+ dosis bajas de esteroides como tratamiento inicial se compararon al inicio del tratamiento, a los 6 y 12 meses en sus parámetros de laboratorio y características clínicas. Al final del primer año, 4 de 6 pacientes (66,7 %) con dosis bajas de ciclosporina e inhibidores de la calcineurina y 6 de 7 pacientes (85,7 %) con ciclosporina presentaron remisión (p>0,05). Conclusión: Se encontró que el tratamiento inicial con esteroides y el tratamiento con inhibidores de la calcineurinason igualmente efectivos. Pensamos que, a los pacientes con intolerancia a los esteroides, se les podría administrarinhibidores de la calcineurinaen el primer paso, pero si se considera el costo, la primera opción son nuevamente los esteroides, como lo recomienda el consorcio Kidney Disease Improving Global Outcomes.

Serum ADMA, endothelial dysfunction, and atherosclerosis in hypervolemic hemodialysis patients

Background/aim: Asymmetric dimethyl arginine (ADMA) is a strong predictor of cardiovascular disease and mortality in patients under hemodialysis treatment. We aimed to investigate the relationship among volume status, endothelial dysfunction, and ADMA in hemodialysis patients. Materials and methods: A total of 120 patients with a history of hemodialysis treatment were included. ADMA and CRP were measured. Echocardiographic evaluation and carotid artery intima-media thickness (CIMT) measurements were performed. Patients were divided into two groups according to clinical evaluation, ultrafiltration rate, vena cava inferior diameter (VCI), and cardiothoracic index (CTI); the two groups were hypervolemic and normovolemic. Results: The hypervolemic group included 61 patients while the normovolemic group included 59 patients. CIMT was higher in the hypervolemic group, but this result was not statistically significant (0.95 mm versus 0.85 mm, P = 0.232). There was a statistically significant difference between the hypervolemic and normovolemic groups in terms of ADMA (P < 0.001) (0.69 ± 0.57 µmol/L and 0.41 ± 0.04 µmol/L, respectively). Positive correlations were observed between serum ADMA, VCI, CTI, CRP, CIMT, and cardiac mass (P < 0.001, P = 0.016, P < 0.001, P = 0.006, P = 0.022, respectively), and negative correlations were observed between ADMA and ejection fraction and albumin (P = 0.024, P = 0.024, respectively). In multiple linear regression analysis, ADMA was independently associated with age, systolic blood pressure, CTI, and volume status. Conclusion: ADMA may be a potential determinant of hypervolemia as well as atherosclerosis in patients under hemodialysis treatment.

The association between serum hepcidin-25 level and subclinical atherosclerosis in peritoneal dialysis patients.

OBJECTIVE: Recently, the role of hepcidin as a cardiovascular marker in the chronic kidney disease (CKD) population has gained interest. The aim of this study was to investigate the relationship between serum hepcidin-25, inflammation, iron parameters, and carotid intima-media thickness (CIMT) in peritoneal dialysis (PD) patients. METHODS: A total of 58 patients (30 male, 51.3%; mean age: 46.8±13.6 years; mean dialysis duration: 69.2±39.1 months) were included in this cross-sectional study. Clinical and routine laboratory data were recorded and the CIMT and hepcidin values were determined. The study population was divided into 2 groups according to the median hepcidin value of 60 ng/mL. Correlation analysis and logistic regression analysis were performed to determine the relationship between the hepcidin level and other parameters. RESULTS: Age (p=0.003), systolic blood pressure (p=0.039), body mass index (p=0.031), glucose (p=0.028) level, C-reactive protein (CRP) level (p<0.001), and CIMT (p=0.011) were found to be statistically significantly higher in the high hepcidin group. In correlation analysis, hepcidin was positively correlated with age (p<0.001), dialysis duration (p=0.041), glucose (p=0.015), ferritin (p=0.005), CRP (p<0.001), and CIMT (p=0.035). In multivariate linear regression analysis, age (p<0.001) and CRP (p=0.005) were found to be related to CIMT. CONCLUSION: Hepcidin-25 was strongly associated with both age and CRP in patients undergoing PD treatment. The results suggest that hepcidin may be involved in the pathophysiology of atherosclerosis. Prospective studies should be carried out in this patient population to determine whether hepcidin has an effect on atherosclerosis.

Relation between high serum hepcidin-25 level and subclinical atherosclerosis and cardiovascular mortality in hemodialysis patients.

OBJECTIVE: In hemodialysis (HD) patients, cardiovascular disease (CVD) is the major cause of mortality and morbidity. In atherosclerotic diseases, iron gets accumulated in the arterial wall. Hepcidin is an important hormone in iron metabolism. Furthermore, hepcidin is associated with atherosclerotic disease. Therefore, this study aims to investigate the relation of serum hepcidin-25 (SH-25) and sub-clinic atherosclerosis measured by carotid intima-media thickness (CIMT) and mortality in HD patients. METHODS: We enrolled 82 HD patients in a cross-control study. We measured SH-25 using ELISA kit and CIMT using high-resolution real-time ultrasonography. After 4 years of first assessment, we investigated the relation between all-cause and cardiovascular mortality and SH-25 and CIMT. RESULTS: Two patients were excluded because of renal transplantation. The survivors were younger (53.7±15.1 vs. 65.2±15.5; p<0.05) and CIMT was lower (0.83±0.2 vs. 0.95±0.2; p<0.05); however, there was no significant difference in SH-25 levels between the groups (29.1±13 vs. 32.4±22.4; p=0.767). The patients who died of CVD were significantly older (63.7±16.1 vs. 53.7±15.1; p<0.05) and had significantly higher CIMT (0.94±0.2 vs. 83±0.2; p<0.05). The SH-25 levels were statistically significantly higher in patients who died of CVD (40.3±25 vs. 29.1±13; p<0.05). Linear regression analysis showed a positive correlation between CIMT and SH-25 in the study population and in those who died from CVD (r=0.41; p<0.05 and r=0.606; p<0.05, respectively). CONCLUSION: This study suggests that hepcidin is effective in cardiovascular mortality and pathophysiology of subclinical atherosclerosis in HD patients.

Increased serum renalase in hemodialysis patients: is it related to left ventricular hypertrophy?

INTRODUCTION: Left ventricular hypertrophy (LVH) is one of the most common cardiac abnormalities in patients with end stage renal disease (ESRD). Hypertension, diabetes, increased body mass index, gender, age, anemia, and hyperparathyroidism have been described as risk factors for LVH in patients on dialysis. However, there may be other risk factors which have not been described yet. Recent studies show that renalase is associated with cardiovascular events. The aim of this study was to reveal the relation between renalase, LVH in patients under hemodialysis (HD) treatment. METHODS: The study included 50 HD patients and 35 healthy controls. Serum renalase levels and left ventricle mass index (LVMI) were measured in all participants and the relation between these variables was examined. FINDINGS: LVMI was positively correlated with dialysis vintage and C-reactive protein (CRP) (r = 0.387, p = 0.005 and r = 0.597, p < 0.001, respectively) and was negatively correlated with residual diuresis and hemoglobin levels (r = -0.324, p = 0.022 and r = -0.499, p < 0.001, respectively). There was no significant association of renalase with LVMI in the HD patients (r = 0.263, p = 0.065). Serum renalase levels were significantly higher in HD patients (212 ± 127 ng/mL) compared to controls (116 ± 67 ng/mL) (p < 0.001). Renalase was positively correlated with serum creatinine and dialysis vintage (r = 0.677, p < 0.001 and r = 0.625, p < 0.001, respectively). DISCUSSION: In our study, LVMI was correlated with dialysis vintage, residual diuresis, CRP, and hemoglobin. LVMI tends to correlate with renalase and this correlation may be significant in studies with more patient numbers. The main parameters affecting renalase levels are dialysis vintage and serum creatinine.

Serum apelin is associated with affective disorders in peritoneal dialysis patients.

OBJECTIVE: Depression and anxiety are prevalent affective disorders in peritoneal dialysis (PD) patients. Recent research has proposed a potential role of apelinergic system in pathogenesis of depression. The present study aimed to evaluate the frequency of depression and anxiety and their potential relation with serum apelin levels among PD patients. METHODS: A total of 40 PD patients were enrolled into the study. Depressive symptoms and anxiety were assessed with the Beck's Depression Inventory and the Beck's Anxiety Inventory. Serum apelin-12 levels were measured by immunoenzymatic assays using commercially available ELISA kit for standard human apelin. RESULTS: Of the patients, 16 (40%) had depression, 20 (50%) had anxiety. The patients with depression and anxiety had a significantly longer time on dialysis (p < 0.001 for both), significantly higher serum apelin (p < 0.001 for both) and C-reactive protein levels (p < 0.001 for both) than those without depression and anxiety. In multivariate analysis, serum apelin was the only parameter associated independently with depression and anxiety scores. CONCLUSIONS: A substantial number of PD patients had depression and anxiety. Increased levels of serum apelin may constitute a significant independent predictor of development of depression and anxiety in PD patients.

Is hepcidin-25 a predictor of atherosclerosis in hemodialysis patients?

Atherosclerotic cardiovascular disease is an important cause of mortality and morbidity in hemodialysis patients. Iron accumulation in arterial wall macrophages is increased in atherosclerotic lesions. Hepcidin is a key hepatic hormone regulating iron balance. It inhibits iron release from macrophages and iron absorption from enterocytes by binding and inactivating the cellular iron exporter ferroportin. The aim of this study is to investigate the relation of hepcidin-25, iron parameters, and atherosclerosis measured by carotid intima media thickness (CIMT) in hemodialysis patients. Eighty-two hemodialysis patients were enrolled in this cross-sectional study. Predialysis blood samples were centrifuged at 1500 g and 4°C for 10 minutes and stored at -80°C for the measurement of hepcidin-25. DRG hepcidin enzyme-linked immunosorbent assay kit was used for the measurement of hepcidin-25. Ultrasonographical B-mode imaging of bilateral carotid arteries was performed with a high-resolution real-time ultrasonography (Mindray DC7). Mean age of the study population was 57.90 ± 16.08 years and 43.9% were men. Total study population was grouped into two according to median value of hepcidin-25. There was no difference between groups with respect to age, dialysis vintage, and C-reactive protein. CIMT was found to be statistically significantly higher in low hepcidin-25 group. In correlation analysis, CIMT was found to be correlated with age (P < 0.01, R = 0.33) and hepcidin-25 (P < 0.01, R = 0.46). In linear regression analysis, age (ß = 0.31) and hepcidin-25 (ß = 0.44) were found to be the determinants of CIMT in hemodialysis patients. Our results implicate that hepcidin may take part in pathophysiology of atherosclerosis and cardiovascular disease in hemodialysis patients.

Fibroblast growth factor is associated to left ventricular mass index, anemia and low values of transferrin saturation / El factor de crecimiento fibroblástico está asociado con el índice de masa ventricular izquierda, anemia y niveles bajos de saturación de la transferrina

Background: Fibroblast growth factor 23 (FGF-23) is a phosphorus-regulating hormone. In chronic kidney disease (CKD), circulating FGF-23 levels are markedly elevated and independently associated with mortality. Left ventricular hypertrophy (LVH) is a potent risk factor for mortality in CKD, and FGFs have been implicated in the pathogenesis of myocardial hypertrophy. In addition, the effect of anemia on CV disease and LVH is well known in CKD. A relation between iron and FGF-23 metabolism is mentioned in a few studies. The aim of this study was to test the association of FGF-23 levels with echocardiographic (ECHO) and iron parameters in peritoneal dialysis patients (PD). Methods: In this cross-sectional study, 61 subjects with PD (29 women and 32 men, mean age: 46.9±13.3 years, mean PD vintage: 69.5±39 months) underwent echocardiograms to assess left ventricular mass index (LVMI). Medical treatments and average values of the basic laboratory results of the last 6 months for all patients were recorded. Serum FGF- 23 concentrations were measured using intact FGF-23 (iFGF-23) human enzyme-linked immunosorbent assay (ELÿISA) kit. According to the median levels of serum FGF-23 the patients were grouped into two (FGF-23 high and low groups). Results: Significant positive correlation was recorded between serum FGF-23 levels and LVMI (P = 0.023). There was also significant difference in terms of hemoglobin (12.1±2 versus 11.0±2, P = 0.017), transferrin saturation (TSAT) (24.9±16.8 versus 19.5±10.8, P = 0.042) between low and high FGF-23 group. Also in linear regression analysis the negative relation between FGF-23 and hemoglobin is persisted (r = 0.199, P = 0.045). Conclusions: FGF-23 is associated with LVMI, anemia and low TSAT in patients with PD. Whether increased FGF-23 is a marker or a potential mechanism of myocardial hypertrophy and anemia in patients with end-stage renal disease (ESRD) requires further study (AU)

Introducción: El factor de crecimiento fibroblástico 23 (FGF-23) es una hormona reguladora del fósforo. En la enfermedad renal crónica (ERC), los niveles de FGF-23 son especialmente elevados y se relacionan de manera independiente con mortalidad. La hipertrofia ventricular izquierda (HVI) es un importante factor de riesgo de mortalidad en la ERC y se ha implicado a los FGF en la patogenia de la hipertrofia del miocardio. Además, se conoce el efecto de la anemia en la enfermedad cardiovascular y la HVI en la ERC. En algunos estudios se menciona una relación entre el hierro y el metabolismo del FGF-23. El objetivo de este estudio fue comprobar la asociación de los niveles de FGF-23 con parámetros ecocardiográficos y de hierro en pacientes con diálisis peritoneal (DP). Metodología: En este estudio transversal se procedió a realizar un ecocardiograma a 61individuos con DP (29mujeres y 32 hombres; media de edad: 46,9±13,3 años; DP clásica media: 69,5±39 meses) para evaluar el índice de masa ventricular izquierda (IMVI). Se registraron los tratamientos médicos y los valores promedio de los resultados básicos de laboratorio de los últimos 6 meses de todos los pacientes. Las concentraciones en suero del FGF-23 se midieron con el kit ELISA (enzyme-linked immunosorbent assay) de FGF-23 humano intacto (iFGF-23). Según los niveles promedio de FGF-23 en suero, los pacientes se distribuyeron en dos grupos (FGF-23 alto y bajo). Resultados: Se registró una correlación positiva significativa entre los niveles de FGF-23 en suero e IMVI (P = 0,023). También hubo diferencias significativas en cuanto a la hemoglobina (12,1±2 frente a 11,0±2, P = 0,017) y saturación de la transferrina (TSAT; 24,9±16,8 frente a 19,5±10,8, P = 0,042) entre los grupos de FGF-23 bajo y alto. También en el análisis de regresión lineal se mantuvo la relación negativa entre el FGF-23 y la hemoglobina (r = 0,199, P = 0,045). Conclusiones: El FGF-23 se asocia con IMVI, anemia y TSAT baja en pacientes con DP. Saber si el aumento del FGF-23 es un marcador o un mecanismo potencial de la hipertrofia miocárdica y la anemia en pacientes con insuficiencia renal terminal exige un estudio en mayor detalle (AU)

Do elevated plasma S100A12 levels predict atherosclerosis in peritoneal dialysis patients?

AIM: Atherosclerotic cardiovascular disease is one of the major causes of mortality and morbidity in peritoneal dialysis (PD) patients. S100A12 is an endogenous receptor ligand of advanced glycation end-products. It was shown to contribute to the development of atherosclerosis in animal models. The aim of this study was to evaluate the relationship between S100A12 levels and carotid atherosclerosis in PD patients. METHODS: A cross-sectional study was performed in 56 PD patients and 20 control subjects. Plasma S100A12 levels were measured from all participants beside routine laboratory evaluation. All subjects underwent high-resolution B-mode ultrasonography to determine carotid intima media thickness (CIMT). S100A12 levels were compared between patient and control groups. Correlation analyses of S100A12 with other laboratory values and CIMT were also performed. RESULTS: Plasma S100A12 levels were higher in PD patients compared with control subjects (129.5 ± 167.2 ng/mL vs. 48.5 ± 30.3 ng/mL, respectively, p < 0.001). In the patient group, CIMT was found to be positively correlated with age (r = 0.354; p = 0.007), CRP level (r = 0.269; p = 0.045), and S100A12 (r = 0.293; p = 0.028) level while it was found to be negatively correlated with hemoglobin concentration (r = -0.264; p = 0.049). In the linear regression analysis, the model, including CRP, S100A12, age, and Hgb, was found to be significant (F: 4.177, p: 0.005). When the parameters are analyzed age and S100A12 were found to be independent determinants of CIMT (ß = 0.308, p = 0.018 and ß = 0.248, p = 0.049, respectively). CONCLUSIONS: This study suggests that an elevated plasma S100A12 level was closely associated with atherosclerosis. With aging elevated plasma S100A12 may show a powerful proatherogenic potential in patients undergoing PD.

The relation between apelin levels, echocardiographic findings and carotid intima media thickness in peritoneal dialysis patients.

BACKGROUND: Cardiovascular disease (CVD) is the most important cause of morbidity and mortality in patients with end stage renal disease (ESRD). Apelin expressed in endothelial and other tissues including brain and kidney is an adipocytokine defined recently and is emerging an important mediator of cardiovascular homeostasis. The aim of this study was to test whether apelin levels might be associated with carotid artery atherosclerosis and left ventricular mass index (LVMI) in peritoneal dialysis patients. PATIENTS AND METHODS: Fifty peritoneal dialysis patients (25 female, mean age 41.4 ± 11.9 years, mean dialysis vintage 65.0 ± 35.4 months) and 18 healthy individuals (9 female, mean age 41.7 ± 6.8 years) were included in this cross-sectional study. Serum apelin 12 levels, echocardiographic findings and carotid intima media thickness (CIMT) were recorded as well as clinical and laboratory data. RESULTS: There were no differences between the patient and the control groups with regard to demographic characteristics. In patient group, LVMI, CIMT, CRP and apelin levels were elevated compared to control group. However there was no association between apelin, LVMI and CIMT. There was a positive correlation between apelin and CRP, which was not statistically significant. When patients were divided into two groups according to the mean serum apelin levels, LVMI, CIMT and CRP were higher in the high apelin group but this difference did not reach statistical significance. CONCLUSION: We observed an increased inflammation and CVD risk in peritoneal dialysis patients. However, serum apelin levels seem not to be associated with cardiovascular risk in this group of patients.

H pylori infection in patients with Behcet's disease.

AIM: To evaluate endoscopic findings and the prevalence of H pylori in patients with Behcet's disease (BD) who have upper gastrointestinal symptoms. METHODS: The patients with BD diagnosed according to the International Study Group and followed up in the Department of Dermatology and other related departments and who had any upper gastrointestinal complaints, were included in this study. Forty-five patients with BD and 40 patients in the control group were evaluated by upper gastrointestinal endoscopy and two biopsied specimens were taken during endoscopy for H pylori. A two-week triple therapy for H pylori eradication was administered to H pylori positive patients. Two months after the treatment, the patients were evaluated by urea-breath test for eradication control. RESULTS: Patients with BD had a mean age of 36.2 +/- 11.4 years (18-67 years). The mean follow-up time was 35 +/- 14 mo (16-84 mo). Aphthous or deep ulcer in esophagus, stomach and duodenum had never been confirmed by endoscopic examination. Most gastric lesions were gastric erosion (40%) and the most duodenal lesions were duodenitis (17.5%) in two groups. H pylori was positive in 33 patients (73.3%) with BD. The two-week triple eradication therapy was successful in 75% of the patients. There was no difference between the groups in respect to prevalence of H pylori (73.3% vs 75%, P > 0.05), and eradication rate (75% vs 70%, P > 0.05). CONCLUSION: Endoscopic findings, eradication rate and prevalence of H pylori were similar in patients with BD and control group.
