Abstract
INTRODUCTION We aimed to evaluate the relationship between the hand fine motor skills of peritoneal dialysis (PD) practitioners and PD-related peritonitis. METHODS This multicenter prospective observational study was conducted with 120 incident PD patients. Patients were divided into two groups who had PD-related peritonitis within the first year as Group 1, and those who did not as Group 2. Hand fine motor skills were evaluated by Nine-Hole Peg Test (NHPT) and Nut Screwing Test (NST). RESULTS Initial NHPT (28.5 ± 6.0 s vs. 25.8 ± 5.0 s, p = 0.011) and NST (82.3 (61.5-102.8) s versus 65.3 (52.3-88.5) s p = 0.023) scores were significantly higher in Group 1 than Group 2. In multivariate logistic regression analysis, NHPT, Body Mass Index, Mini-Mental Test, self PD practitioner, and catheter complications were found to be independent variables in predicting PD-related peritonitis. CONCLUSION Decreased hand fine motor skills of PD patients is a risk factor for peritonitis.

Abstract
BACKGROUND Patients who were urgent start peritoneal dialysis (USPD) were evaluated in terms of complications. METHODS The data from 102 patients (43 males and 59 females, mean age 58.18 ± 15.3 years) who were on peritoneal dialysis with a placed catheter between January 2014 and June 2019 in our Nephrology clinic was evaluated. The patients were divided into three groups according to the starting time of peritoneal dialysis. The development of complications between the groups (peritonitis, leakage, hernia), hemodialysis return time and overall survival times were compared. RESULTS There was no difference between the groups in terms of survival and complications. Diabetes, advanced age, albumin values were found to be risk factors for mortality, while no differences were found between the groups in terms of complications and mortality. CONCLUSION USPD can be recommended for both because it provides a permanent dialysis option and because it leads to fewer complications than urgent start HD.

Abstract
INTRODUCTION Hyponatremia is one of the most common electrolyte abnormalities in clinical practice. Data regarding factors that have impact on mortality of severe hyponatremia and outcomes of its therapeutic management is insufficient. The present study aimed to examine the factors associated with mortality and the outcomes of treatment in patients with severe hyponatremia. MATERIALS AND METHODS Patients with serum Na≤115mequiv./L who were admitted to Ordu State Hospital and Ordu University Training and Research Hospital between 2014 and 2018 were included in the study. Demographic and laboratory features, severity of the symptoms, comorbid diseases, medications, and clinical outcome measures of the patients were obtained retrospectively from their medical records. Factors associated with in-hospital mortality, overcorrection and undercorrection were assessed. RESULTS A total of 145 patients (median age 69 years and 58.6% female) met inclusion criteria. Diuretic use was the most common etiologic factor for severe hyponatremia that present in 50 (34.5%) patients. Sixty-seven (46.2%) patients had moderately severe while 8 patients (5.5%) had severe symptoms. The median increase in serum Na 24h after admission in the study population was 8.9mequiv./L (-6 to 19). Nonoptimal correction was seen in 92 (63.4%) patients. Hypertonic saline use was associated with overcorrection (OR, 3.07; 95% CI: 1.47-6.39; p=0.002). Avoidance of hypertonic saline (aOR, 2.52; 95% CI: 1.12-5.66; p=0.029) and having neuropsychiatric disorder (aOR, 2.60; 95% CI: 1.10-6.11; p=0.025) were associated with undercorrection. In-hospital mortality rate was 12.4% and having CKD and cancer, undercorrection of sodium and presence of severe symptoms were significantly associated with in-hospital mortality. CONCLUSION Severe hyponatremia in hospitalized patients is associated with substantial mortality. The incidence of non-optimal correction of serum Na is high; under-correction, presence of severe symptoms, chronic kidney disease and cancer were the factors that increase mortality rate.

Abstract
Background Renal transplantation (RT) has been demonstrated to improve left ventricular systolic function. However, only few studies have attempted to reveal the effects of transplantation on left atrial (LA) function. In our study, we aimed to compare LA function between RT and hemodialysis patients. Methods This cross-sectional study included 75 consecutive patients with RT, and 75 age- and gender-matched patients on maintenance hemodialysis. LA strain and strain rate (SR) analyzed by two-dimensional (2D) speckle tracking echocardiography (STE) were compared between the groups in addition to standard echocardiographic parameters. Results LA strain during reservoir phase (29.88 ± 5.76% vs 26.11 ± 5.74%, P < .001), LA strain during conduit phase (− 15.28 ± 5.00% vs − 12.92 ± 4.38%, P = .003), and LA strain during contraction phase (− 14.60 ± 3.32% vs − 13.19 ± 3.95%, P = .020) were higher in the transplantation group. Similarly, LA peak SR during reservoir phase (1.54 ± 0.33 s− 1 vs 1.32 ± 0.33 s− 1, P < .001), LA peak SR during conduit phase (− 1.47 ± 0.49 s− 1 vs − 1.12 ± 0.42 s− 1, P < .001), and LA peak SR during contraction phase (− 2.13 ± 0.46 s− 1 vs − 1.83 ± 0.58 s− 1, P = .001) were higher in the transplantation group as well. Conclusions LA function assessed by 2D STE was better in RT patients than hemodialysis patients. This may suggest favorable effects of RT on LA function.

Abstract
Background Osteoporosis is a common public health problem in chronic kidney patients. The risk factors for osteoporosis in patients with nondialysis CKD have not been fully investigated. It is not known exactly whether the risk factors of osteoporosis in the general population are also valid for the nondialysis CKD patients. Aims: This study aims to determine the frequency of osteoporosis and the risk factors for osteoporosis in nondialysis CKD patients. Patients and Methods Our study was performed with 283 nondialysis stage 3-5 CKD patients. According to the BMD results, the patients were classified into groups as normal, osteopenia and osteoporosis according to World Health Organization criteria. Monocyte/high-density lipoprotein-cholesterol ratio (MHR), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) were calculated individually for all cases. Results According to our BMD results, 67 (24%) patients were found to have osteoporosis. In the osteoporosis patient group, compared to the normal BMD group, females were higher and the mean age was higher (P = 0.025, P = 0.028). Body mass index (BMI) and eGFR were lower in the osteoporosis group (P = 0.013). Parathyroid Hormone and Platelet-to-lymphocyte ratio in the patients in the osteoporosis group was higher than of those in the normal group (P = 0.026, P = 0.035). In the multivariate logistic regression analysis, advanced age, female gender, and low BMI were determined as independent risk factors for the development of osteoporosis in nondialysis CKD patients. Conclusion Advanced age, female gender and low BMI are the risk factors for osteoporosis in nondialysis CKD patients. It may be a rational approach to measure BMD for the diagnosis of osteoporosis in nondialysis CKD patients who are elderly, female and have low BMI.

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are systemic autoimmune diseases that may lead to renal failure due to the infiltration of mononuclear cells and the destruction of small- and medium-sized blood vessels. It has been shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may trigger the presentation or exacerbation of autoimmune diseases. Crescentic glomerulonephritis (GN) has rarely been reported in patients with Coronavirus disease-2019 (COVID-19). We present rare two cases with AAV after a recent diagnosis of COVID-19. The first case was 26-year-old male patient, who was presented with acute kidney injury after COVID-19. Serum creatinine increased and active urine sediment was seen. Serological evaluation showed anti-myeloperoxidase antibody was at a level of 80.6 U/mL. Kidney biopsy showed necrotizing GN with cellular crescents. Methylprednisolone, cyclophosphamide and plasma exchange were administered. He was discharged with hemodialysis. Second case was a 36-year-old female who was hospitalized because of fever, cough and dyspnea. After she was diagnosed with COVID-19, she had total hearing loss, with cavitary lesions on bilateral lung parenchyma and an acute kidney injury. Serological evaluation showed an elevated anti-proteinase-3 with a level of 1:32. Kidney biopsy showed necrotizing GN with cellular crescents. Renal function improved after methylprednisolone and cyclophosphamide treatment. With a systematic review of the literature, we found four cases of new-onset AAV due to COVID-19. Herein, we discuss two cases and provide a literature review on cases of new-onset pauci-immune GN after COVID-19 infection.

Abstract
INTRODUCTION AND OBJECTIVE IMA and MPO are elevated in serum in case of end-stage renal disease. Epicardial fat tissue thickness has been considered an indicator for cardiovascular diseases recently. The present study was aimed to examine the relationship of epicardial fat tissue thickness (EFTT) with IMA and MPO levels in patients with CKD. MATERIALS AND METHODS Predialysis CKD patients admitted to the Nephrology outpatient clinic, patients on haemodialysis and healthy volunteers were included, 111 patients were in the study. EFTT measurement was performed with the transthoracic view using an ECHO device. RESULTS The analysis conducted among the groups in terms of IMA, MPO levels, and EFTT revealed a statistically significant difference (p < 0.001). It was determined to be the lowest in the healthy volunteers, slightly increased in the pre-dialysis group whereas it was quite high in the haemodialysis group. According to the correlation test performed, we observed that IMA, MPO levels, and EFTT were found to be highly correlated to progression of CKD. CONCLUSION We believe that we have introduced three novel follow-up parameters, such as: IMA, MPO, EFTT to literature for the follow-up of CKD. As the levels of IMA MPO and EFTT increase, the severity of CKD increases (Tab. 4, Fig. 1, Ref. 25).

Abstract
Aims Chronic kidney disease (CKD) is a serious health problem due to high mortality and morbidity, negative impact on the patients' quality of life (QOL), high diagnostic and therapeutic cost, and the burden on society. Sleep, which is one of the main needs of the human body, is important regarding the health and QOL in all ages. The objective of our study was to plan the quality of sleep and life quality in adults with CKD. Materials and Methods Total 240 cases (91 healthy volunteers, 75 predialysis patients, and 74 hemodialysis (HD) patients) were included in our study. Our study was designed as a prospective survey with a face-to-face interview method. The sleep quality was evaluated with Pittsburgh Sleep Quality Index (PSQI). The WHO Quality of Life-short version (BREF) survey questions were used for QOL, and scoring was performed. Results The analysis showed that the results of PSQI scores, QOL scores, and evaluation of the age variable were statistically significant (P = 0.001, P < 0.001, P < 0.001, respectively). Likewise, the PSQI scores were low in healthy volunteers but were the highest in predialysis patients. The scores of the HD patients were between the scores of predialysis and healthy volunteers. The score of the QOL increased with educational level. There was a positive correlation between Modification of Diet in Renal Disease (MDRD) level and QOL (P < 0.001; r = 0.260) and a negative correlation between MDRD level and PSQI score (P < 0.001, r = -0.202). Conclusion Like in HD patients, close follow-up of predialysis patients with CKD is critical considering the resolution of the encountered problems. We believe that the increase in QOL and sleep in patients with CKD may decrease the morbidity.

PURPOSE Renal infarction is a clinical condition which is caused by renal artery occlusion and leads to permanent renal parenchymal damage. In the literature, there are generally case reports on this subject, and few studies that include a large group of patients. Therefore, we aimed to present the data of a large group of patients who were diagnosed with acute renal infarction in our country in this retrospective study. METHODS The data of patients who were diagnosed with acute renal infarction according to clinical and radiological findings in Turkey in the last 3 years were examined. For this purpose, we contacted with more than 40 centers in 7 regions and obtained support from clinically responsible persons. Demographic data of patients, laboratory data at the time of diagnosis, tests performed for etiologic evaluation, given medications, and patients' clinical status during follow-up were obtained from databases and statistical analysis was performed. RESULTS One-hundred and twenty-one patients were included in the study. The mean age was 53 ± 1.4 (19-91) years. Seventy-one (58.7%) patients were male, 18 (14.9%) had diabetes, 53 (43.8%) had hypertension, 36 (30%) had atrial fibrillation (AF), and 6 had a history of lupus + antiphospholipid syndrome (APS). Forty-five patients had right renal infarction, 50 patients had left renal infarction, and 26 (21.5%) patients had bilateral renal infarction. The examinations for the ethiologies revealed that, 36 patients had thromboemboli due to atrial fibrillation, 10 patients had genetic anomalies leading to thrombosis, 9 patients had trauma, 6 patients had lupus + APS, 2 patients had hematologic diseases, and 1 patient had a substance abuse problem. Fifty-seven (57%) patients had unknown. The mean follow-up period was 14 ± 2 months. The mean creatinine and glomerular filtration rate (GFR) values at 3 months were found to be 1.65 ± 0.16 mg/dl and 62 ± 3 ml/min, respectively. The final mean creatinine and GFR values were found to be 1.69 ± 0.16 mg/dl and 62 ± 3 ml/min, respectively. CONCLUSIONS Our study is the second largest series published on renal infarction in the literature. More detailed studies are needed to determine the etiological causes of acute renal infarction occurring in patients.

Abstract
AIM We investigated the relationship of monocyte to high-density lipoprotein cholesterol ratio (MHR) with diabetes mellitus and diabetic nephropathy. METHODS & RESULTS A total of 220 diabetes mellitus patients and 70 healthy controls were enrolled. There was no difference in an MHR between normoalbuminuric diabetic patients and the healthy controls. The MHR in patients with diabetic nephropathy was significantly higher than that of both the normoalbuminuric diabetic patients and the healthy controls. There was a significant positive correlation between urine albumin to creatinine ratio and the MHR. In multivariate linear regression analysis, the MHR was independently correlated with urine albumin to creatinine ratio. Conclusion: An increased MHR may be a biomarker for diabetic nephropathy.

Abstract
INTRODUCTION The most important complication of familial Mediterranean fever (FMF) is secondary amyloidosis, which can lead to kidney failure. Genetic variability in the genes of various components of the renin-angiotensin system may play a role in the pathogenesis of the kidney disorders. The aim of the present study was to investigate the association between angiotensin converting enzyme (ACE) gene I/D variant and risk of developing FMF-related amyloidosis in Turkish patients. MATERIALS AND METHODS A total of 240 individuals consisting of 40 patients with FMF-related amyloidosis, 100 FMF patients without amyloidosis, and 100 healthy controls were recruited. For all of the participants, ACE I/D variant was detected by the polymerase chain reaction using specific primers. RESULTS A significant difference was found between the patients with FMF-related amyloidosis and the control group as for genotype distribution of ACE I/D variant (P < .05). The ACE D/D and I/D genotypes were more frequent in the patients with FMF-related amyloidosis while the I/I genotype was less frequent in the same patients. The FMF patients (with and without amyloidosis) had significantly higher percentages of the D/D and I/D genotypes than the healthy controls (P < .05). Comparison between the subgroups of FMF patients, divided into those with and without amyloidosis, yielded a significant correlation according to ID+II versus DD genotypes (P < .03, odds ratio, 3.24; 95% confidence interval, 1.05 to 12.01). Conclusions. Based on these observations, the ACE I/D variant D/D genotypes implicate a possible risk in the FMF-related amyloidosis among Turkish population.

Abstract
UNLABELLED Central nervous system (CNS) metastasis is a rare event in the course of late stage epithelial ovarian cancer (EOC); however its incidence is increasing in parallel with prolonged survival of patients. OBJECTIVE The authors assessed the clinical parameters and potential prognostic features in patients with CNS metastatic disease. MATERIALS AND METHODS Clinical data of the 33 patients from the participating centers were retrospectively collected and analyzed. Median age at the time of CNS metastasis was 57 years. Median time from the diagnosis of primary EOC until CNS metastatic disease was 22 months. Nearly half (45.5%) of the patients had single CNS metastatic lesions and all patients in the study group except two received radiotherapy as palliative treatment. Median overall survival (OS) from the time of CNS metastasis was 15 months (0-66). At univariate analysis only number of brain metastatic lesions (p = 0.001) and presence of extracranial disease (p = 0.004) were strongly associated with OS whereas multimodal treatment, size of metastatic lesions, platinum sensitivity, age, grade, and disease stage at presentation were not. Development of CNS metastasis carries a poor prognosis, however patients with single metastatic lesions and only intracranial metastatic disease can have prolonged survival after appropriate palliative management of their disease.

Abstract
INTRODUCTION Familial Mediterranean fever (FMF) is a recessively inherited disease which is characterized by recurrent episodic fever, abdominal pain, and polyserositis. It is caused by mutations in the MEFV gene, encoding the pyrin protein. The most important complication of FMF is secondary (AA) amyloidosis that leads to kidney failure. This study aimed to identify the frequency and distribution of MEFV mutations in Turkish patients with FMF-associated AA amyloidosis. MATERIALS AND METHODS A total of 57 patients with FMF-associated AA amyloidosis and 60 healthy controls were included in this study. We analyzed the MEFV gene for E148Q, M694V, M680I, and V726A mutations and R202Q variant by polymerase chain reaction and restriction fragment length polymorphism methods. Results. The male-female ratio was 0.72. The mean age of the patients was 29.8 ± 12.8 years. Among the patients, the rate of the MEFV mutations was found to be 77.2%. The most frequently observed genotype was homozygous M694V mutation, which was present in 17 patients (29.8%, P < .001), followed by compound heterozygous M680I/M694V (14.3%, P = .01). The R202Q allele frequencies were significantly different between patients and control group (P = .02; odds ratio, 0.53; 95% confidence interval, 0.30 to 0.94). CONCLUSIONS In this study, mutation analysis of MEFV gene confirmed that the most frequent mutation was homozygous M694V genotype. R202Q may be important in patients with FMF-associated AA amyloidosis. Thus, it is suggested that investigation of R202Q should be considered as a genetic test for Turkish FMF patients.

Abstract
Although kidney transplantation (KT) is widely used for treating renal amyloidosis secondary to familial Mediterranean fever (FMF), data concerning transplant outcome are limited and inconsistent. The aim of this study was to determine the long-term outcome of KT in patients with amyloidosis secondary to FMF. Kidney transplantation outcome in 24 patients with FMF was compared to that in 72 controls matched for age, gender of recipient, and type of the donor that underwent KT due to end-stage renal disease (ESRD) not caused by FMF. Mean follow-up time was 80.3 ± 55.1 months in the FMF group, vs. 86.5 ± 47.6 months in the control group. Death-censored graft survival at five and 10 yr in the FMF group was 95.8% and 78.4%, respectively, and was comparable to that in the control group. In the FMF group, five- and 10-yr patient survival (87.5 and 65.6%) was shorter than in the control group, but the difference was not statistically significant. The findings show that long-term outcome of KT in the patients with amyloidosis secondary to FMF was comparable to that in patients with ESRD not caused by FMF. Recurrence of amyloidosis in the allograft, gastrointestinal intolerance, and fatal infections remain as major complications during the post-transplant period.

Abstract
BACKGROUND Bleeding is the most frequent complication of kidney biopsy. Although bleeding risk in patients with AA amyloidosis after kidney biopsy has not been studied in a large population, AA amyloidosis has long been perceived as a risk factor for bleeding. The aim of the present study was to evaluate post-biopsy bleeding risk in patients with AA amyloidosis. METHODS We retrospectively analyzed bleeding complications in 88 patients with AA amyloidosis and 202 controls after percutaneous kidney biopsy. All the kidney biopsies were performed under the guidance of real-time ultrasound with the use of an automated core biopsy system after a standard pre-biopsy screening protocol. Bleeding events were classified as major when transfusion of blood products or surgical or radiological intervention was required, or if the bleeding caused hypovolemic shock or death. Bleeding events that did not meet these criteria were accepted as minor. RESULTS The incidence of post-biopsy bleeding was comparable between AA amyloidosis and control groups (5.7 vs. 5.0%, p = 0.796). Major bleeding events were observed in 3 patients from each group (p = 0.372). Selective renal angiography and embolization were applied to 2 patients from the AA amyloidosis group. One of these patients underwent colectomy and died because of infectious complications. Bleeding events were minor in 2.3% of the patients with AA amyloidosis and 3.5% of the controls (p = 0.728). CONCLUSIONS AA amyloidosis was not associated with increased post-biopsy bleeding risk. Kidney biopsy is safe in AA amyloidosis when standard pre-biopsy screening is applied. Further data are needed to confirm these findings.

Abstract
The glomerular tip lesion (GTL) is a distinctive histopathologic lesion which is regarded as a variant of focal and segmental glomerulosclerosis (FSGS). The prognostic significance of GTL among other FSGS variants has been disputed. In order to define the clinical features and outcome of GTL, we retrospectively reviewed the presenting clinical features, laboratory and biopsy findings and surveillance in our cohort of GTL, which consisted of 20 adults with native kidneys (mean age 46 years) with follow-up data ranging from 3 to 137 months. At presentation, mean urine protein, serum albumin and cholesterol levels were 5.17 g/d, 2.6 g/dL and 312.9 mg/dL, respectively, and none had renal insufficiency. Microscopic hematuria was detected in five patients. At biopsy, glomerular segmental lesions consisted of GTL without perihilar or collapsing lesions. GTL was observed in a variable proportion of glomeruli from 2.6% to 100%. Mesangial proliferation was seen in nine cases, at a moderate degree in two and mild in the rest. Three biopsies showed mild, two showed moderate interstitial fibrosis/tubular atrophy. Eleven patients received steroids alone and eight received sequential therapy with steroids and a cytotoxic agent. At a mean follow-up of 40.6 months, 17 patients (85%) achieved complete remission of nephrotic syndrome, 15% had partial remission. Four of 17 suffered from recurrences. No patient progressed to end-stage renal disease. Serum albumin at diagnosis was the only predictor of a recurrence (p = 0.037). Microscopic hematuria correlated with incomplete remission (p = 0.045). Our study demonstrates a clearly favorable prognosis in patients with FSGS-GTL variant.

Abstract
BACKGROUND Endothelial dysfunction can be detected at early stages of chronic kidney disease. Although endothelial functions improve after successful renal transplantation, renal transplant recipients have still worse endothelial functions compared to healthy subjects. Vitamin D deficiency and high fibroblast growth factor-23 (FGF-23) levels may have a role on endothelial dysfunction in chronic kidney disease patients. The aim of this study is to investigate the association between endothelial functions, vitamin D, and FGF-23 levels in renal transplant recipients. METHODS One hundred nine renal transplant recipients (71 male, 38 female) underwent brachial flow-mediated dilatation (FMD), serum 25-OH vitamin D, and FGF-23 level measurements. Vitamin D and FGF-23 levels were compared between patients with normal and abnormal endothelial functions. Correlations between FMD, vitamin D, and FGF-23 were also investigated. RESULTS Endothelial functions were abnormal in 72.5% of the patients. Prevalence of vitamin D deficiency was 80.7%. Vitamin D levels were significantly lower in patients with endothelial dysfunction compared to patients with normal endothelial functions (12.6 ± 6.6 μg/L vs 17.3 ± 10.0 μg/L respectively, P = .02). FGF-23 levels were not different between the two groups. 25-OH vitamin D levels had a significant positive correlation with amount of FMD (r = 0.218 and P = .02) and were an independent predictor of FMD after adjusting for potential confounding factors including age, transplantation duration, body mass index, mean blood pressure, glomerular filtration rate, proteinuria, hemoglobin, and FGF-23 in multivariate regression analysis (beta = 0.194, P = .04). FGF-23 levels were not predictive of FMD in this model (beta: -0.125, P = .197) CONCLUSION: Vitamin D deficiency is associated with endothelial dysfunction in renal transplant recipients. Further clinical and experimental studies are necessary to define a causal relationship between the parameters, discover the potential mechanisms, and observe the effect of vitamin D replacement on endothelial functions in renal transplant recipients.

Abstract
BACKGROUND/AIMS Hypertension is an important cardiovascular risk factor in renal transplant recipients. Elevated blood pressure variability (BPV) during 24-h ambulatory blood pressure monitoring (ABPM) is associated with increased risk of target organ damage and cardiovascular events, independent of mean blood pressure levels. We aimed to evaluate the relationship between endothelial function, blood pressure levels obtained by various measurement methods, and BPV in renal transplant recipients. METHODS In total, 73 hypertensive renal transplant recipients were included in the study. Office blood pressure measurements, central blood pressure measurements, home blood pressure measurements and 24-h ABPM were obtained from the subjects. BPV was calculated using the average real variability index. All patients underwent brachial flow-mediated vasodilatation tests. Predictive values of blood pressures obtained by different measurement techniques and BPV on endothelial functions were investigated. RESULTS Endothelial dysfunction was present in 68.5% of the patients. No difference was found between the group with and without endothelial dysfunction with regard to office systolic or diastolic blood pressure, central blood pressure or home systolic blood pressure. In the group with endothelial dysfunction, 24-h ambulatory systolic blood pressure and night-time ambulatory systolic blood pressure were higher. In patients with endothelial dysfunction, the 24-h systolic, diastolic and mean BPV were all higher. There was also a negative correlation between the percentage of flow-mediated vasodilatation with 24-h mean and systolic BPV. CONCLUSION Patients with endothelial dysfunction had significantly higher ambulatory blood pressure values and higher BPV. There was a significant negative correlation between endothelial function and BPV.

Abstract
Congenital megacalycosis is a rare renal disease characterized by calyceal dilatation without pelvic or ureteral obstruction. If not accompanied by nephrolithiasis and urinary tract infection, this disease is completely benign and does not cause renal dysfunction. We present a case of congenital megacalycosis that was diagnosed at the age of 41 (oldest case in the literature) after admitting with hematuria and acute renal dysfunction. IgA nephropathy was also diagnosed in this patient. Since renal dysfunction is not likely in these patients, if encountered; renal biopsy should be performed although technically difficult to diagnose the cause of this dysfunction.

Abstract
OBJECTIVE The aim of this study was to evaluate the relationship of local intrarenal renin angiotensin system (RAS) with proteinuria in patients with renal AA amyloidosis. METHODS Thirty-two patients with renal AA amyloidosis (19 male, mean age: 45 ± 13 years) and sixteen healthy controls (5 male, mean age: 32 ± 5 years) were included in this study. Spot urine samples were obtained to measure urinary angiotensinogen (AGT) using human AGT-ELISA, urinary creatinine and protein levels. Logarithmic transformations of urinary AGT-creatinine ratio log(UAGT/Ucre) and urinary protein-to-creatinine ratio (UPCR) were done to obtain the normal distributions of these parameters. RESULTS Log(UAGT/UCre) was significantly higher in patients compared with the controls (1.88 ± 0.92 µg/g vs. 1.25 ± 0.70 µg/g; p = 0.023). Importantly a significantly positive correlation was found between log(UAGT/Ucre) and logUPCR in patients (r = 0.595, p = 0.006). CONCLUSIONS Urinary AGT levels are higher in renal AA amyloidosis patients than in controls. Also, there is a significant positive correlation between urinary AGT and proteinuria in renal AA amyloidosis.

Abstract
The aim of this study was to evaluate the relationship of local intrarenal renin angiotensin system (RAS) with hypertension and proteinuria in renal transplant recipients. Sixty-nine nondiabetic renal transplant recipients (39 male, mean age: 36.3 ± 11.5 years) were included in this study. All patients were in stable condition with GFR greater than 30 ml/min/1.73 m(2); (MDRD). Hypertension was defined to be present if there was a recorded diagnosis of hypertension, systolic blood pressure >130 mmHg and/or diastolic blood pressure >80 mmHg according to ambulatory blood pressure monitoring. None of the hypertensive patients were receiving RAS blockers. Spot urine samples were obtained to measure urinary angiotensinogen (AGT) using human AGT-ELISA, urinary creatinine and protein levels. The demographic properties and laboratory findings were similar between hypertensive and normotensive transplant recipients. Urinary AGT-creatinine ratio (UAGT/UCre) was significantly higher in hypertensive patients compared with the normotensives (8.98 ± 6.89 μg/g vs. 5.48 ± 3.33 μg/g; P = 0.037). Importantly, a significantly positive correlation was found between UAGT/Ucre levels and proteinuria in hypertensive patients (P = 0.01, r = 0.405). Local intrarenal RAS probably plays an important role in the development of hypertension and proteinuria in renal transplant recipients.

Abstract
Immunosuppressants are the cornerstones of treatment after solid organ transplantation. This study investigated the pathology and cell proliferation following partial hepatectomy (PH) in rats undergoing immunosuppressive treatment. After 1 day, all rats were subjected to 70% PH. Groups A and B (n = 10) received calcineurin inhibitors subcutaneously: either FK506 or cyclosporine (CyA). Groups C and D (n = 10) received antiproliferative drugs: either mycophenolate mofetil (MMF) or sirolimus (SRL) by gavage. A control group (n = 5) received 1 mL of tap water daily. On postoperative day 2, all rats were sacrificed to obtain liver tissue for pathologic examination. Using immunohistochemistry we separately examined the hepatectomy surface and the liver parenchyma. In the parenchyma, the Ki-67 indices were higher in the CyA and FK506 groups and lower in the SRL and MMF groups compared with controls (P < .01). CyA had the highest and MMF the lowest values. On the hepatectomy surface, Ki-67 indices and TGF-alpha expressions were higher in the CyA group and lower in the SRL and MMF groups compared with the control group (P < .01). Slightly higher values in the FK506 group were not significantly different compared with the control group (P > .05). All groups other than FK506 showed prominent cholangiolar epithelial phenotypes compared with the control group. In the CyA and SRL groups, the number of cholangiolar cells was higher (P < .01), and in the MMF group lower than in the control group (P < .01). Among all groups, SRL had the highest values.

Abstract
PURPOSE We aimed to investigate the effects of methylene blue (MB) on NO production, myeloperoxidase (MPO) activity, antioxidant status and lipid peroxidation in lung injury during different stages of sepsis in rats. MATERIAL AND METHODS Rats were randomly divided into 4 groups (n = 20): group C, sham operated; group CMB, sham operated and receiving MB (25 mg/kg, i.p.); group S, sepsis; group SMB, sepsis and receiving MB (25 mg/kg, i.p.). Sepsis was induced by cecal ligation and puncture (CLP). The MB dose was administered after CLP. Each group was subdivided into two subgroups (n = 10) which were sacrificed at 9 or 18 h after the surgical procedure. The levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX) and MPO activity, total nitrite/nitrate and malondialdehyde (MDA) in the lung tissue were measured. Lung injury was graded from 1 (injury to 25% of the field) to 4 (diffuse injury) by the pathologist. RESULTS In group SMB, while SOD and CAT increased in both early and late sepsis periods, GSH-PX increased significantly only in the early sepsis period when compared with group S. Increase in lung MPO activity after CLP-induced sepsis was prevented by MB administration. MB significantly decreased to nitrite/nitrate and MDA levels both in early and late sepsis periods when compared with group S (p < 0.05). Group S showed a marked increase in neutrophil infiltration into the interstitial space and thickening of the alveolar septa, whereas the alveolar damage score was lower in the SMB group (p < 0.05). CONCLUSION MB reduced the MPO activity and lipid peroxidation by both decreasing oxidative stress and NO overproduction in the lungs, which resulted in the attenuation of lung injury after CLP-induced sepsis in rats.

Abstract
We reviewed a case of Brucella spondylodiscitis admitted to a referral, university hospital, in Ankara, Turkey. A 75-year-old female was referred to our hospital with low back pain. Previous magnetic resonance imaging yielded cortical destruction of T9-10 and T12-L2 vertebral bodies, focal infectious foci at discs within this range, significant microabscesses at paravertebral areas, which lead to the diagnosis of spondylodiscitis. History of consumption of unpasteurized dairy products led us to first suspect brucellosis yet, the serum agglutination test and blood culture were negative and did mislead us to several other, sometimes invasive, diagnostic tests. The final diagnosis was reached by culturing the specimen obtained through fine-needle aspiration from the paravertebral microabscesses. The exhausting diagnostic journey that started with the suspicion of tuberculosis or malignancy ended with a diagnosis of brucellosis. Brucellosis should be considered in all patients with osteoarthritic complaints in endemic regions, and the "prozone phenomenon" should be kept in mind, before proceeding to high-tech lab tests, imaging, or invasive procedures.
