Abstract
Immune mechanisms play an important role in the pathogenesis of glomerulonephritis (GN), with autoimmunity being the main underlying pathogenetic process of both primary and secondary GN. We present three autoimmune diseases mediated by different autoimmune mechanisms: glomerulonephritis in vasculitis mediated by anti-neutrophil cytoplasmic antibodies (ANCAs), glomerulonephritis mediated by anti-glomerular basement membrane antibodies (anti-GBM antibodies), and immune complex-mediated glomerulonephritis. Some of these diseases represent a common clinical and histopathologic scenario, namely rapidly progressive crescentic glomerulonephritis. This is a severe illness requiring complex therapy, with the main role being played by therapy aimed at targeting immune mechanisms. In the absence of immune therapy, the crescents, the characteristic histopathologic lesions of this common presentation, progress toward fibrosis, which is accompanied by end-stage renal disease (ESRD). The fact that three diseases mediated by different immunopathologic mechanisms have a common clinical and histopathologic picture reveals the complexity of the relationship between immunopathologic mechanisms and their clinical expression. Whereas most glomerular diseases progress by a slow process of sclerosis and fibrosis, the glomerular diseases accompanied by glomerular crescent formation can progress, if untreated, in a couple of months into whole-nephron glomerulosclerosis and fibrosis. The outcome of different immune processes in a common clinical and histopathologic phenotype reveals the complexity of the relationship of the kidney with the immune system. The aim of this review is to present different immune processes that lead to a common clinical and histopathologic phenotype, such as rapidly progressive crescentic glomerulonephritis.

Abstract
(1) Introduction and Aims: Little is known about the relationship between renal pathology and gallbladder pathology, although the two organs (the gallbladder and the right kidney) are in close proximity to one another. If a renal abscess disseminates, the gallbladder would be one of the secondary organs involved. As the bile provides a favorable environment for the development of pathogenic germs, it allows for the development of acute cholecystitis, even if calculi are absent, thus resulting in the development of acute acalculous cholecystitis. The aim of our study was to analyze the association between acute acalculous cholecystitis (AAC) and renal abscesses. (2) Methods: A department-wide retrospective cohort observational study including 67 patients with renal abscesses, with a mean age of 34.5+/-16.21 years and with five males and 62 females, was conducted. All of the patients were examined by an abdominal ultrasound. The lab tests included CBC with differential liver enzymes and serum bilirubin (in order to assess alterations in the liver function which can be associated with AAC) and serum creatinine (in order to assess the renal function). Blood culture and urine culture tests were also performed. (3) Results: Of the 67 patients with renal abscesses, eight (11.94%) were associated with acute cholecystitis: four cases (5.97%) of acalculous cholecystitis and four cases (5.97%) of calculous cholecystitis, two of which presented biliary sludge (acute micro-calculous cholecystitis). All four cases of acute acalculous cholecystitis presented with sepsis, and there was one case of septic shock at onset. We did not observe an impairment in renal function in the patients presenting with acute acalculous cholecystitis, and hepatic impairment was inconstant and moderate. All of the cases had a favorable outcome after a prompt initiation of intensive antibiotic therapy; both the renal abscess and the acute acalculous cholecystitis receded without further complications. (4) Conclusions: The association of acute acalculous cholecystitis with renal abscesses could be related to the possibility of germ dissemination from the infectious focus. In the case of a renal abscess, careful clinical, lab, and imaging exams of the gallbladder are recommended in order to ensure early therapeutic intervention in the event of an association with acute acalculous cholecystitis.

Abstract
Abstract
BACKGROUND AND AIMS
Metabolic biomarkers are of high importance for the identification of early renal involvement in the course of type 2 diabetes mellitus (DM). Gangliosides, which are complex cell type-specific glycosphingolipids, consist of a sialylated oligosaccharide chain attached to a ceramide of different composition with respect to the sphingoid base and fatty acid residues [1]. Gangliosides play a major role in the pathogenesis of diabetic kidney disease (DKD). The aim of the study was to assess the pattern of urinary gangliosides in patients with type 2 DM.
METHOD
The urine gangliosidome of 30 type 2 DM patients (10 normo-, 10 micro-, and 10 macroalbuminuric) has been investigated in a cross-sectional pilot study, by a comparative assay with 10 healthy controls. Following the optimization of urine ganglioside extraction procedure [2, 3], we have determined the composition of native ganglioside mixtures from the 24-h collected urine samples using a modern bioanalytical platform based on nanoelectrospray ionization (nanoESI) high-resolution mass spectrometry (HR MS) on an Orbitrap instrument.
RESULTS
HR MS screening and fragmentation analysis by tandem MS revealed that: (i) the urinary gangliosidome of type 2 DM patients contains a significantly higher number of distinct species differing in either their glycan or ceramide structure than the controls; (ii) the ganglioside urinary level was significantly increased in normoalbuminuric patients compared with healthy control subjects; (iii) the gangliosidome of macroalbuminuric patients is characterized by an elevated overall sialic acid content than normo- and microalbuminuric diabetics and more complex structures, including fucosylated, O-GalNAc- and CH3COO--modified compounds; (iv) the degree of sialylation of species presented correlations with the level of albuminuria and renal function; (v) further detailed structural analysis of a type GQ1(d18:1/18:0) species (identified only in macroalbuminuric patients) demonstrated that the present isomer is of type D (all four syalic acids are linked to the inner galactose).
CONCLUSION
HR MS by tandem MS methods, using an Orbitrap instrument, are a reliable tool for the identification of a particular ganglioside profile in the urine of type 2 DM patients. The sialylated species and those altered by peripheral attachments to the glycan core might be considered useful indicators of early DKD.

Abstract
Abstract
Background and Aims
Glomerular injury and proximal tubule (PT) dysfunction have intricate mechanisms in diabetic kidney disease (DKD). Pro-inflammatory cytokines are involved in the initiation and progression of DKD through mediating the inflammatory response, both at glomerular and proximal tubular level. miRNAs are able to modulate cellular and biochemical functions, thus intervening in the pathogenesis of DKD.
The aim of the study, performed on patients with type 2 diabetes mellitus (DM), was to evaluate selective pro-inflammatory cytokines in relation to biomarkers of podocyte lesion and of PT dysfunction. Particular molecular pathways, such as specific miRNA profiles operating in this relation, have also been studied.
Method
A number of 126 patients with type 2 DM, staged by albuminuria [39 normoalbuminuric – urinary albumin/creatinine ratio UACR)<30mg/g; 45 microalbuminuric–UACR-30–300mg/g; 42 macroalbuminuric–UACR>300mg/g], and 23 healthy control subjects were included in a cross-sectional study. All patients were evaluated concerning biomarkers of podocyte injury (nephrin, podocalyxin, synaptopodin) and of PT dysfunction [Kidney injury molecule-1(KIM-1), N-acetyl-beta-D-glucuronidase (NAG), alpha 1- microglobulin]. Also, serum and urinary levels of specific interleukins (IL-6, IL-17), serum cystatin C, and eGFR were determined. Serum and urinary miRNAs (miRNA-21, miRNA-124, miRNA-146a, miRNA-192) were assessed by RT-PCR.
Results
The biomarkers of podocyte lesion and of PT dysfunction were increased, even in normoalbuminuric type 2 DM patients. Serum and urinary IL-6 and IL-17 showed increased levels in type 2 DM patients, across all groups studied. The model provided by univariable regression analysis showed that IL-6 and IL-17 correlated directly with biomarkers of podocyte injury (nephrin, podocalyxin, synaptopodin), of PT dysfunction (KIM-1, NAG, alpha 1-microglobulin), as well as with UACR. Negative correlations have been identified regarding eGFR.
In multivariable regression analysis, serum IL-6 correlated directly with synaptopodin, NAG, and negatively with eGFR (p<0.00001, R2=0.805); serum IL-17 correlated directly with synaptopodin, NAG, KIM-1, UACR, and negatively with eGFR (p<0.00001, R2=0.941); urinary IL-6 correlated directly with synaptopodin, NAG, and negatively with eGFR (p<0.00001, R2=0.889); urinary IL-17 correlated directly with synaptopodin, nephrin, NAG, and negatively with eGFR (p<0.00001, R2=0.905).
Also, important associations were found between specific interleukins and miRNAs. In univariable regression analysis, IL-6 and IL-17 correlated directly with miRNA-21 and miRNA-124, and negatively with miRNA-146a and miRNA-192. The models provided by multivariable regression analysis showed that urinary IL-6 correlated directly with urinary miRNA-21, and negatively with urinary miRNA-192 (p<0.00001, R2=0.886). Urinary IL-17 displayed direct correlations with urinary miRNA-21, and negative correlations with urinary miRNA-192 (p<0.00001, R2=0.860). Serum IL-6 correlated directly with serum miRNA-21, miRNA-124, and indirectly with serum miRNA-146a, miRNA-192 (p<0.00001, R2=0.862). Serum IL-17 showed direct correlations with serum miRNA-21, miRNA-124, and negative correlations with serum miRNA-192 (p<0.00001, R2=0.745).
Conclusion
In the early stages of DKD, there is an association of pro-inflammatory cytokines with specific miRNAs, and with biomarkers of podocyte injury and of PT dysfunction. IL-6 and IL-17, as well as dysregulated miRNA-21, miRNA-124, miRNA-146a, and miRNA-192 display a particular molecular pattern, in relation to complex mechanisms that can initiate and maintain the chronic inflammatory response in DKD. Routine detection of these interleukins may provide biomarkers to refine the diagnosis of early renal involvement in the course of type 2 DM, independently of albuminuria and level of renal function.

Abstract
Aims: Long noncoding RNAs (lncRNAs) play key roles in the pathophysiology of DKD involving actions of microRNAs (miRNAs). The aims of the study were to establish the involvement of selected lncRNAs in the epigenetic mechanisms of podocyte damage and tubular injury in DKD of type 2 diabetes mellitus (DM) patients in relation to a particular miRNAs profile. Methods: A total of 136 patients with type 2 DM and 25 healthy subjects were assessed in a cross-sectional study concerning urinary albumin: creatinine ratio (UACR), eGFR, biomarkers of podocyte damage (synaptopodin, podocalyxin) and of proximal tubule (PT) dysfunction (Kidney injury molecule-1-KIM-1, N-acetyl-D-glucosaminidase-NAG), urinary lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), nuclear-enriched abundant transcript 1 (NEAT1), myocardial infarction-associated transcript (MIAT), taurine-upregulated gene 1 (TUG1), urinary miRNA21, 124, 93, 29a. Results: Multivariable regression analysis showed that urinary lncMALAT1 correlated directly with urinary synaptopodin, podocalyxin, KIM-1, NAG, miRNA21, 124, UACR, and negatively with eGFR, miRNA93, 29a (p<0.0001; R2=0.727); urinary lncNEAT1 correlated directly with synaptopodin, KIM-1, NAG, miRNA21, 124, and negatively with eGFR, miRNA93, 29a (p<0.0001; R2=0.702); urinary lncMIAT correlated directly with miRNA93 and 29a, eGFR (p<0.0001; R2=0.671) and negatively with synaptopodin, KIM-1, NAG, UACR, miRNA21, 124 (p<0.0001; R2=0.654); urinary lncTUG1 correlated directly with eGFR, miRNA93, 29a, and negatively with synaptopodin, podocalyxin, NAG, miRNA21, 124 (p<0.0001; R2=0.748). Conclusions: In patients with type 2 DM lncRNAs exert either deleterious or protective functions within glomeruli and PT. LncRNAs may contribute to DKD through modulating miRNAs expression and activities. This observation holds true independently of albuminuria and DKD stage.

Abstract
Aim: An advanced proteomics platform for protein biomarker discovery in diabetic chronic kidney disease (DKD) was developed, validated and implemented. Materials & methods: Three Type 2 diabetes mellitus patients and three control subjects were enrolled. Urinary peptides were extracted, samples were analyzed on a hybrid LTQ-Orbitrap Velos Pro instrument. Raw data were searched using the SEQUEST algorithm and integrated into Proteome Discoverer platform. Results & discussion: Unique peptide sequences, resulted sequence coverage, scoring of peptide spectrum matches were reported to albuminuria and databases. Five proteins that can be associated with early DKD were found: apolipoprotein AI, neutrophil gelatinase-associated lipocalin, cytidine deaminase, S100-A8 and hemoglobin subunit delta. Conclusion: Urinary proteome analysis could be used to evaluate mechanisms of pathogenesis of DKD.

Abstract
Background: The association of vascular remodeling in the kidney and the brain with a particular microRNAs (miRNA) profile is not well studied.Methods: Seventy-six patients with Type 2 diabetes and 11 healthy subjects were assessed concerning urine albumin: creatinine ratio (UACR), biomarkers of podocyte injury and of proximal tubule (PT) dysfunction. MiRNA were quantified in blood and urine by a real-time PCR System. Cerebrovascular ultrasound measurements were performed in the carotid and middle cerebral arteries.Results: MiRNA21 and miRNA124 correlated positively with nephrin, podocalyxin, synaptopodin, urinary N-acetyl-D-glucosaminidase (NAG), urinary kidney-injury molecule-1 (KIM-1), UACR, and negatively with eGFR; miRNA125a, 126, 146a, 192 correlated negatively with nephrin, podocalyxin, synaptopodin, urinary NAG, urinary KIM-1, UACR, and directly with eGFR. Plasma miRNA-21 and miRNA192 correlated directly with cerebral hemodynamics parameters of atherosclerosis and arteriosclerosis. MiRNA-124, 125a, 126, 146a showed negative correlations with the same parameters.Conclusions: In Type 2 diabetes patients there is an association of vascular remodeling in the brain and the kidney with a specific miRNAs pattern. Cerebrovascular changes occur even in normoalbuminuric patients, with 'high-to-normal' levels of podocyte injury and PT dysfunction biomarkers. These phenomena may be explained by the variability of miRNA expression within the two organs in early DKD.

Abstract
AIMS To evaluate if there is a link between inflammation (expressed by inflammatory cytokines) and the early stage of diabetic kidney disease (DKD), as shown by markers of podocyte damage and proximal tubular (PT) dysfunction. METHODS In this study were enrolled 117 type 2 DM patients (36-normoalbuminuria, 42-microalbuminuria, 39- macroalbuminuria), and 11 healthy subjects. Serum and urinary IL-1 alpha, IL-8, IL-18, urinary albumin:creatinine ratio (UACR), eGFR, biomarkers of podocyte damage (podocalyxin, synaptopodin, nephrin) and of PT dysfunction (KIM-1, NAG) were assessed. RESULTS In multivariable regression urinary Il-1 alpha correlated positively with podocalyxin and NAG (p < 0.0001, R2= 0.57); urinary IL-8 correlated directly with synaptopodin, NAG, nephrin, and KIM-1 (p < 0.0001, R2 = 0.67); urinary IL-18 correlated directly with synaptopodin, NAG, and nephrin (p < 0.0001, R2 = 0.59). Serum IL-1 alpha correlated positively with nephrin, synaptopodin, NAG (P < 0.0001, R2 = 0.68); serum IL-8 correlated directly with synaptopodin and NAG (p < 0.0001, R2 = 0.66); serum IL-18 correlated directly with NAG, KIM-1, and podocalyxin (p < 0.0001, R2=0.647). CONCLUSIONS Pro-inflammatory interleukins are associated with podocyte injury and PT dysfunction in early DKD. These could exert a key role in the pathogenesis of early DKD, before the development of albuminuria.

Abstract
Aim: The involvement of proinflammatory interleukins (IL) in diabetic kidney disease of Type 2 diabetes mellitus (DM) patients was studied in relation to a particular miRNA profile. Materials & methods: A total of 117 patients with Type 2 DM and 11 controls were enrolled in a case series study. Serum and urinary ILs and miRNAs were assessed. Results: IL-1α correlated with miRNA21, 124, estimated glomerular filtration rate (eGFR) and negatively with miRNA125a and 192; IL-8 with miRNA21, 124, eGFR and negatively with miRNA125a, 126 and 146a; IL-18 with miRNA21, 124 and negatively with miRNA146a, 192, eGFR. Conclusion: There is an association between specific serum and urinary ILs and serum and urinary miRNAs profiles in the inflammatory response in Type 2 DM patients with diabetic kidney disease.

Abstract
MicroRNAs (miRNAs) are short non-coding RNA species that are important post-transcriptional regulators of gene expression. The aim of the study was to establish a potential explanation of podocyte damage and proximal tubule (PT) dysfunction induced by deregulated miRNAs expression in the course of type 2 diabetes mellitus (DM). A total of 68 patients with type 2 DM and 11 healthy subjects were enrolled in a cross-sectional study and assessed concerning urinary albumin:creatinine ratio (UACR), urinary N-acetyl-β-D-glucosamininidase (NAG), urinary kidney injury molecule-1, urinary nephrin, podocalyxin, synaptopodin, estimated glomerular filtration rate (eGFR), urinary miRNA21, miRNA124, and miRNA192. In univariable regression analysis, miRNA21, miRNA124, and miRNA192 correlated with urinary nephrin, synaptopodin, podocalyxin, NAG, KIM-1, UACR, and eGFR. Multivariable regression analysis yielded models in which miRNA192 correlated with synaptopodin, uNAG, and eGFR (R2=0.902; P<0.0001), miRNA124 correlated with synaptopodin, uNAG, UACR, and eGFR (R2=0.881; P<0.0001), whereas miRNA21 correlated with podocalyxin, uNAG, UACR, and eGFR (R2=0.882; P<0.0001). Urinary miRNA192 expression was downregulated, while urinary miRNA21 and miRNA124 expressions were upregulated. In patients with type 2 DM, there is an association between podocyte injury and PT dysfunction, and miRNA excretion, even in the normoalbuminuria stage. This observation documents a potential role of the urinary profiles of miRNA21, miRNA124, and miRNA192 in early DN. Despite their variability across the segments of the nephron, urinary miRNAs may be considered as a reliable tool for the identification of novel biomarkers in order to characterize the genetic pattern of podocyte damage and PT dysfunction in early DN of type 2 DM.

Abstract
BACKGROUND Diabetic nephropathy is a severe complication of Type 2 diabetes. Tubular lesions may play an important role in its early stages. The aim of our study was to determine if atorvastatin protects the podocytes and the proximal tubule in patients with Type 2 diabetes. METHODS A total of 63 patients with Type 2 diabetes completed this 6-months prospective pilot study. They were randomized to continue rosuvastatin therapy (control group) or to be administered an equipotent dose of atorvastatin (intervention group), and were assessed regarding urinary podocytes, podocyte-associated molecules, and biomarkers of proximal tubule dysfunction. RESULTS The patients from the intervention group presented a significant reduction in podocyturia (from 7.0 to 4.0 cells/ml, p < .05), urinary nephrin (from 1.7 to 1.3 mg/g, p < .001), urinary vascular endothelial growth factor (from 262.8 to 256.9, p < .01), urinary alpha1-microglobulin (from 10.0 to 8.3 mg/g, p < .01), urinary kidney injury molecule-1 (from 139.5 to 136.3 ng/g, p < .001), and urinary advanced glycation end-products (from 112.6 to 101.3 pg/ml, p < .001). Podocyturia correlated directly with the podocyte damage biomarkers, proximal tubule dysfunction biomarkers, albumin to creatinine ratio, and advanced glycation end-products, and inversely with the glomerular filtration rate. CONCLUSIONS In patients with Type 2 diabetes, atorvastatin exerts favorable effects on the kidney. There is a correlation between the evolution of the podocytes and of the proximal tubule biomarkers, supporting the hypothesis that the glomerular changes parallel proximal tubule dysfunction in the early stages of diabetic nephropathy.

Abstract
INTRODUCTION Acute kidney injury (AKI) increases the risk of death in acute ischemic stroke (AIS) patients. Intravenous thrombolytic therapy (iv. rt-PA) seems to be the most effective treatment for AIS patients. The effects of AKI on iv. rt-PA treated AIS cases is less studied. Our paper addresses this issue. METHODS 45 consecutive stroke patients treated with iv. rt-PA (median age = 64 years; 29 male) and 59 age and sex matched controls not eligible for iv. rt-PA have been enrolled in our study. Subjects were followed-up until hospital release or death (median follow up time = 12 days). RESULTS The prevalence of AKI did not differ between iv. rt-PA treated patients and controls (35.5% vs. 33.89%). In both groups, AKI was associated with increased in-hospital mortality: 50.0% vs. 3.4% p<0.0001 (in the rt-PA treated), and 45% vs. 30.7% (in controls). AKI iv. rt-PA treated patients had a significantly higher risk of in hospital mortality as compared to the no-AKI iv. rt-PA treated (HR = 15.2 (95%CI [1.87 to 124.24]; P = 0.011). In a Cox-multivariate model, the presence of AKI after iv. rt-PA remained a significant factor (HR = 8.354; p = 0.041) influencing the in-hospital mortality even after correction for other confounding factors. The independent predictors for AKI were: decreased eGFR baseline and elevated serum levels of uric acid at admission, (the model explained 60.2% of the AKI development). CONCLUSIONS The risk of AKI was increased in AIS patients. Thrombolysis itself did not increase the risk of AKI. In the iv. rt-PA patients, as compared to non-AKI, those which developed AKI had a higher rate of in-hospital mortality. The baseline eGFR and the serum uric acid at admission were independent predictors for AKI development in the iv. rt-PA treated AIS patients.

Abstract
AIMS Detection of podocytes in the urine of patients with type 2 diabetes may indicate severe injury to the podocytes. In the course of type 2 diabetes the proximal tubule is involved in urinary albumin processing. We studied the significance of podocyturia in relation with proximal tubule dysfunction in type 2 diabetes. METHODS A total of 86 patients with type 2 diabetes (34-normoalbuminuria; 30-microalbuminuria; 22-macroalbuminuria) and 28 healthy subjects were enrolled in the study and assessed concerning urinary podocytes, podocyte-associated molecules, and biomarkers of proximal tubule dysfunction. Urinary podocytes were examined in cell cultures by utilizing monoclonal antibodies against podocalyxin and synaptopodin. RESULTS Podocytes were detected in the urine of 10% of the healthy controls, 24% of the normoalbuminuric, 40% of the microalbuminuric, and 82% of the macroalbuminuric patients. In multivariate logistic regression analysis, urinary podocytes correlated with urinary albumin:creatinine ratio (p=0.006), urinary nephrin/creat (p=0.001), urinary vascular endothelial growth factor/creat (p=0.001), urinary kidney injury molecule-1/creat (p=0.003), cystatin C (p=0.001), urinary advanced glycation end-products (p=0.002), eGFR (p=0.001). CONCLUSIONS In patients with type 2 diabetes podocyturia parallels proximal tubule dysfunction independently of albuminuria and renal function decline. Advanced glycation end-products may impact the podocytes and the proximal tubule.

Abstract
AIM The study assessed mRNA expression of podocyte-associated molecules in urinary sediments of patients with type 2 diabetes mellitus (DM) in relation to urinary podocytes, biomarkers of podocyte injury and of proximal tubule (PT) dysfunction. METHODS A total of 76 patients with type 2 DM and 20 healthy subjects were enrolled in a cross-sectional study, and assessed concerning urinary podocytes, urinary mRNA of podocyte-associated genes, urinary biomarkers of podocyte damage and of PT dysfunction. RESULTS We found significant differences between urinary mRNA of podocyte-associated molecules in relation with albuminuria stage. In multivariable regression analysis, urinary mRNA of nephrin, podocin, alpha-actinin-4, CD2-associated protein, glomerular epithelial protein 1 (GLEPP1), ADAM 10, and NFκB correlated directly with urinary podocytes, albuminuria, urinary alpha1-microglobulin, urinary kidney-injury molecule-1, nephrinuria, urinary vascular endothelial growth factor, urinary advanced glycation end-products (AGE), and indirectly with eGFR (p < 0.0001, R2 = 0.808; p < 0.0001, R2 = 0.825; p < 0.0001, R2 = 0.805; p < 0.0001, R2 = 0.663; p < 0.0001, R2 = 0.726; p < 0.0001, R2 = 0.720; p < 0.0001, R2 = 0.724). CONCLUSIONS In patients with type 2 DM there is an association between urinary mRNA of podocyte-associated molecules, biomarkers of podocyte damage, and of PT dysfunction. GLEPP1, ADAM10, and NFκB may be considered additional candidate molecules indicative of early diabetic nephropathy. AGE could be involved in this association.

Abstract
The solitary kidney (SK) undergoes adaptive phenomena of hyperfunction and hyperfiltration. These secondary adaptive phenomena can make it more vulnerable to potentially nephrotoxic therapies. Adverse reactions of the kidneys to ciprofloxacin are rare, but sometimes severe. Therefore, our study sought to assess the reactions to ciprofloxacin of patients with solitary kidney (SK) and urinary tract infection (UTI) by means of urinary biomarkers. We studied 19 patients with SK and urinary tract infection (UTI) who had been administered a 7-day treatment with intravenous ciprofloxacin. Urinary N-acetyl-beta-d-glucosaminidase, alpha 1-microglobulin, and estimated glomerular filtration rate (eGFR) of these patients were measured at the initiation and at the end of treatment. In 47.37% patients NAG diminished under ciprofloxacin treatment. This observation has the significance of favourable evolution of the tubulointerstitial lesions caused by UTI and lack of nephrotoxic effects; 52.63% cases presented an increase of urinary NAG, a fact that suggests a nephrotoxic effect of ciprofloxacin. The evolution of urinary alpha 1-microglobulin was similar to that one of urinary NAG. Only one of three cases with chronic kidney disease (CKD) stage 5 presented acute kidney injury, associated with increase in the tubular markers. In spite of the high variability of the urinary biomarkers, UTI evolved favourably in these cases; eGFR increased in 16 out of 19 patients, a fact which is indicative of a good outcome of renal function, even in patients with elevated levels of the tubular damage biomarkers. This observation supports the hypothesis that eGFR may be dissociated from the biomarkers which assess tubular injury. In SK patients the occurrence of AKI is not frequent, although the urinary biomarkers rise in some patients treated with ciprofloxacin. This is related not only to the nephrotoxic effect of the drug, but probably to the association of other factors (allergy, individual susceptibility). In SK patients, renal tubular biomarkers, especially NAG, allow monitoring of tubular injury and impose caution in prescribing ciprofloxacin treatment, mainly to patients at risk. Ciprofloxacin is relatively safe regarding its nephrotoxicity, while caution is required in vulnerable patients.

Abstract
Diabetic nephropathy (DN) is a frequent and severe complication of diabetes mellitus (DM). Its diagnosis in incipient stages may allow prompt interventions and an improved prognosis. Towards this aim, biomarkers for detecting early DN can be used. Microalbuminuria has been proven a remarkably useful biomarker, being used for diagnosis of DN, for assessing its associated condition-mainly cardiovascular ones-and for monitoring its progression. New researches are pointing that some of these biomarkers (i.e., glomerular, tubular, inflammation markers, and biomarkers of oxidative stress) precede albuminuria in some patients. However, their usefulness is widely debated in the literature and has not yet led to the validation of a new "gold standard" biomarker for the early diagnosis of DN. Currently, microalbuminuria is an important biomarker for both glomerular and tubular injury. Other glomerular biomarkers (transferrin and ceruloplasmin) are under evaluation. Tubular biomarkers in DN seem to be of a paramount importance in the early diagnosis of DN since tubular lesions occur early. Additionally, biomarkers of inflammation, oxidative stress, podocyte biomarkers, and vascular biomarkers have been employed for assessing early DN. The purpose of this review is to provide an overview of the current biomarkers used for the diagnosis of early DN.

Abstract
The relationship between the kidney and other organs is notable. The best known is the relation with the cardiovascular system. Relationships with other organs are less studied, although their involvement sometimes dominates the clinical picture and the outcome of disease. The paper analyzes the kidney-liver relationship, namely chronic kidney disease and chronic liver disease from an immune viewpoint. The immune system operates as a unitary whole. There is an interdependence between the immune system of the liver, considered a lymphoid organ, and the kidney, whose participation in immune processes is well-known. The most important chronic liver diseases are viral hepatitis B and C. Infection with these viruses can lead to renal involvement, producing mainly glomerular disease. At the same time, secondary glomerulonephritis can cause an unfavorable outcome of the primary disease. The relationship between chronic liver disease and chronic kidney disease during chronic B and C hepatitis occurs via circulating immune complexes or complexes formed in situ. Cell-mediated immunity is also involved. The antiviral treatment of B and C hepatitis is also aimed at secondary glomerular disease. The participation of immune mechanisms raises the question of administering immunomodulating medication, a type of medication that influences viral replication--this is why it is associated with antiviral medication. Other two chronic liver diseases, namely liver cirrhosis, in which the main mechanism is a toxic one, and non-alcoholic steatohepatitis can produce via immune mechanisms glomerular involvement. In its turn, chronic kidney disease in advanced stages causes lipid metabolism disturbances with hypertriglyceridemia, which can influence fatty loading of the liver in the above-mentioned liver diseases. One can speak about a cross-talk between the liver and the kidney, in which immune mechanisms play an important role.

Abstract
BACKGROUND Diabetic atherosclerosis and microangiopathy parallel diabetic nephropathy. The aim of our study was to evaluate the pattern of endothelial dysfunction in two vascular territories, the kidney and the brain, both affected by diabetic vasculopathic complications. The endothelial variability was evaluated in relation to advanced glycation end-products modified peptides. METHODS Seventy patients with type 2 diabetes mellitus and 11 healthy subjects were assessed concerning urine albumin: creatinine ratio, plasma and urinary advanced glycation end-products, plasma asymmetric dimethyl-arginine, serum cystatin C, intima-media thickness in the common carotid arteries, the pulsatility index, the resistance index in the internal carotid arteries and the middle cerebral arteries, the cerebrovascular reactivity through the breath-holding test. RESULTS The breath-holding index correlated with asymmetric dimethyl-arginine (R²=0.151; p<0.001), plasma advanced glycation end-products (R²=0.173; p<0.001), C-reactive protein (R²=0.587; p<0.001), duration of diabetes mellitus (R²=0.146; p=0.001), cystatin C (R²=0.220; p<0.001), estimated glomerular filtration rate (R²=0.237; p=0.001). Urine albumin: creatinine ratio correlated with urinary advanced glycation end-products (R²=0.257; p<0.001), but not with asymmetric dimethyl-arginine (R²=0.029; p=0.147). CONCLUSIONS In type 2 diabetic patients endothelial dysfunction in the cerebral vessels appears to be dissociated from glomerular endothelial dysfunction in early diabetic nephropathy. Advanced glycation end-products could impact both the cerebral vessels and the glomerular endothelium.

Abstract
BACKGROUND Advanced glycation end-products have been involved in the pathogenesis of proximal tubule dysfunction which characterizes diabetic tubulopathy. METHODS A total of 76 Type 2 diabetes mellitus patients and 28 healthy controls were evaluated concerning a potential association of glycated peptides with proximal tubule dysfunction by assessing urine albumin:creatinine ratio, urinary alpha1-microglobulin, urinary neutrophil gelatinase-associated lipocalin, plasma and urinary advanced glycation end-products, plasma asymmetric dimethyl-arginine, serum cystatin C. Fully automated chip-nanoelectrospray ionization and high-capacity ion trap multistage mass spectrometry characterized the urinary proteomic profile. RESULTS The urinary glycated proteins displayed a molecular weight of 15,121.4 Da in normoalbuminuric patients and of 30,180.4 Da in microalbuminuric patients. Urinary alpha1-microglobulin and neutrophil gelatinase-associated lipocalin correlated with urinary advanced glycation end-products (R(2)=0.586; R(2)=0.415), urine albumin: creatinine ratio (R(2)=0.292; R(2)=0.116), estimated glomerular filtration rate (R(2)=0.172; R(2)=0.135), serum cystatin C (R(2)=0.146; R(2)=0.129), but not with asymmetric dimethyl-arginine. In multivariable regression analysis models, the correlations for urinary alpha1-microglobulin and neutrophil gelatinase-associated lipocalin remained significant with urine albumin: creatinine ratio, urinary advanced glycation end-products, estimated glomerular filtration rate (P<0.0001, R(2)=0.674; P<0.0001, R(2)=0.551; P<0.0001, R(2)=0.482). CONCLUSIONS In patients with Type 2 diabetes mellitus urinary glycated peptides are associated with proximal tubule dysfunction. The proteomic patterns of urinary glycated peptides could differentiate normo- from microalbuminuric patients and may explain a potential relation between the size and the glycation status of glycated peptides, and the extent of proximal tubule dysfunction. The lack of correlation between parameters of endothelial dysfunction and proximal tubule dysfunction cannot exclude glomerular involvement in early diabetic nephropathy.

Abstract
BACKGROUND There is an ongoing debate as to whether early diabetic nephropathy in Type 2 diabetes mellitus may be attributed to the glomerulus or to the proximal tubule. Urinary excretion of nephrin and vascular endothelial growth factor may increase even in the normoalbuminuria stage. In the course of diabetic nephropathy, the proximal tubule may be involved in the uptake of urinary nephrin and vascular endothelial growth factor. MATERIALS AND METHODS Two groups of consecutive Type 2 diabetes mellitus outpatients (38 normo-, 32 microalbuminuric) and 21 healthy subjects were enrolled in a cross-sectional study and evaluated concerning the relation of proximal tubule dysfunction with the podocyte biomarkers excretion, assessed by ELISA methods. The impact of advanced glycation end-products on this relation was also queried. RESULTS Urinary alpha1-microglobulin and kidney injury molecule-1 correlated with urinary albumin:creatinine ratio (R2 = 0.269; p < 0.001; R2 = 0.125; p < 0.001), nephrinuria (R2 = 0.529; p<0.001; R2 = 0.203; p < 0.001), urinary vascular endothelial growth factor (R2 = 0.709; p < 0.001; R2 = 0.360; p < 0.001), urinary advanced glycation end-products (R2 = 0.578; p < 0.001; R2 = 0.405; p < 0.001), serum cystatin C (R2 = 0.130; p < 0.001; R2 = 0.128; p<0.001), and glomerular filtration rate (R2 = 0.167; p < 0.001; R2 = 0.166; p < 0.001); nephrinuria and urinary vascular endothelial growth factor correlated with urinary albumin:creatinine ratio (R2 = 0.498; p < 0.001; R2 = 0.227; p<0.001), urinary advanced glycation end-products (R2 = 0.251; p < 0.001; R2 = 0.308; p < 0.001), serum cystatin C (R2 = 0.157; p < 0.001; R2 = 0.226; p < 0.001), and glomerular filtration rate (R2 = 0.087; p = 0.007; R2 = 0.218; p < 0.001). CONCLUSIONS In Type 2 diabetes mellitus there is an association of proximal tubule dysfunction with podocyte damage biomarkers, even in the normoalbuminuria stage. This observation suggests a potential role of the proximal tubule in urinary nephrin and urinary vascular endothelial growth factor processing in early diabetic nephropathy, a fact which could be related to advanced glycation end-products intervention. Podocyte damage and proximal tubule dysfunction biomarkers could be validated as a practical approach to the diagnosis of early diabetic nephropathy by further studies on larger cohorts.

Abstract
INTRODUCTION AND AIMS Balkan endemic nephropathy (BEN), a regional tubulointerstitial kidney disease encountered in South-Eastern Europe, with still undefined etiology and inexorable evolution towards end stage renal disease, raises the question of the relative contribution of family and environmental factors in its etiology. In order to evaluate the intervention of these factors, markers of tubular injury have been assessed, this lesion being considered an early renal involvement in BEN. METHODS The paper studies relatives of BEN patients currently included in dialysis programmes (for involvement of the family factor) and their neighbors (for involvement of environmental factors) and analyzes them with regard to tubular injury by means of tubular biomarkers (N-acetyl-beta-d-glucosaminidase-NAG and alpha-1-microglobulin), and albuminuria. At the same time, glomerular filtration rate (GFR) (CKD-EPI) was measured. It is considered that, in order to acquire the disease, one should have lived for 20 years in the BEN area. The relatives have been classified according to this criterion. RESULTS More evident tubular injury was found in the neighbors of BEN patients living for more than 20 years in the endemic area, which argues in favor of environmental factors. Higher levels of urinary alpha-1-microglobulin and albumin in relatives of BEN patients who had been living for more than 20 years in the area than in relatives with a residence under 20 years, plead for the same hypothesis. GFR was lower in persons who had been living for more than 20 years in the BEN area (neighbors and relatives). CONCLUSIONS Environmental factors could be more important in BEN than family factors.

Abstract
The kidneys, as an integral part of the body, are in close functional relationship with other organs. Dysfunction of the relationship with one organ will affect the kidney. Chronic kidney disease (CKD) leads in time to alteration of the relationship of the kidney with other organs, sometimes with severe consequences. Thus, cardiovascular involvement in CKD leads to increased severity of CKD, with an increase in mortality rate. At present, the relationship between the kidney and the lung has been less studied. Many aspects of this relationship are still unknown. The objective of the present paper is to analyze the main situations of the alteration of the kidney-lung relationship in clinical pathology, with special reference to chronic kidney disease. The pulmonary-renal syndrome is at the forefront. This pathology--well known in practice--refers mainly to the kidney-lung relationship in vasculitis, systemic lupus erythematosus and Goodpasture's syndrome. The relationship between the kidney and the lung is not limited to this syndrome. Many systemic diseases like sarcoidosis and amyloidosis alter the lung-kidney binomial. Likewise, the association in some patients of an important disorder primarily affecting the lung, such as silicosis, with concomitant renal involvement, highlights the relationship between the lungs and kidneys in clinical pathology. It is very important to know heart-kidney relationships via the lung in pulmonary arterial hypertension. In-depth knowledge of the patient with chronic kidney disease also requires thorough analysis of the lung-kidney relationship. This relationship is very evident in haemodialysed patients, taking into consideration that the pulmonary circulation is influenced by the dialysis membranes, in patients on peritoneal dialysis and especially in transplanted patients whose kidney-lung relationship has a favorable outcome. Although little dealt with, the relationship between the kidneys and the lungs requires more attention, as it can have important consequences, and appropriate therapy.

Abstract
INTRODUCTION The solitary kidney (SK) may present increased vulnerability to nephrotoxicity because of adaptive phenomena. AIMS Assessing the vulnerability of the SK with urinary tract infections (UTI) to gentamicin by means of urinary biomarkers (N-acetyl-beta-D-glucosaminidase (NAG) and urinary alpha-1-microglobulin), as well as glomerular filtration rate (GFR). METHODS We studied 14 patients with SK with UTI (group A) (mean age 58.07 ± 13.61 years, mean duration of SK 13.55 ± 12.33 years) who were administered gentamicin for 7 days. Group B consisted by 17 patients with SK without any other associated renal pathology (average age 51.17 ± 9.39 years, average existence period of a single kidney 33.23 ± 21.73 years). We also included a third group (group C) represented by nine healthy individuals, with two kidneys. RESULTS Increased values of urinary NAG were found in group B as compared to group C and alpha-1 microglobulin in group A as compared to group B. During treatment with gentamicin, increased values of both NAG and alpha-1-microglobulin in group A were found on day 7 as compared to values before treatment (day 7 NAG=18.99 ± 14.07 U/g creat versus day 0, NAG=5.15 ± 6.54 U/g creat, p=0.004; day 7 alpha-1-microglobulin=20.88 ± 18.84 mg/g creat versus day 0, urinary alpha-1-microglobulin=4.96 ± 6.57 mg/g creat, p=0.003). No statistically significant alterations of GFR were noticed after 7 days of treatment. CONCLUSIONS We found the nephrotoxic effects of gentamicin at tubular level, but not at glomerular level. The nephrotoxic potential of gentamicin in patients with a SK can be monitored by assessing urinary biomarkers during treatment of UTI.

Abstract
AIMS End Stage Renal Disease (ESRD) represents a microinflammatory state accompanied by oxidative stress and an imbalance between pro- and antioxidants. Vitamin C is a highly effective antioxidant, acting to lessen oxidative stress. The aim of our study was to assess the Antioxidant Capacity of Water soluble substances (ACW) and the Antioxidant Capacity of Liposoluble substances (ACL) in patients with Balkan Endemic Nephropathy (BEN) on hemodialysis undergoing Vitamin C therapy as compared to healthy controls. METHODS Twenty-one patients with BEN on hemodialysis (HD), mean age: 63.33 +/- 5.42 years, 6 M and 15 F, were enrolled into the study. All patients received 10 vials of Vitamin C 750 mg/5 ml every 2 months. Eleven apparently healthy subjects, mean age: 63.73 +/- 5.21 years, 6 M and 5 F, served as controls. The photochemiluminescence assay was used to measure the antioxidant activity of plasma samples. The results are presented in equivalent concentration units of Vitamin C for water soluble antioxidants and in equivalent concentration units of Trolox (synthetic Vitamin E) for lipid soluble antioxidants. Both concentrations are expressed in micromols/L. Statistical analysis (non-parametric Wilcoxon test) was performed using NCSS. RESULTS Mean duration since BEN diagnosis was: 8.24 +/- 3.5 years. Mean duration since HD initiation was: 4.92 +/- 3.4 years. Smoking status was negative in all patients. Hypertension was present in 15 patients (71.42%), cardiovascular disease in 10 (47.61%), HCV infection in 13 (61.9%), 1 patient had HBV + HCV infection, 1 had renal tuberculosis, 1 had upper urinary tract cancer, 1 genital cancer, and I autoimmune thyroid disease. The Antioxidant Capacity of Water soluble substances (ACW) in patients with BEN was 477.6 +/- 177.63 micromols/L, significantly higher as compared to controls: 198.05 +/- 196.63 micromols/L; p = 0.01, whereas the Antioxidant Capacity of Liposoluble substances (ACL) in patients with BEN was 33.9 +/- 22.99 micromols/L, non-significantly different as compared to controls: 27.38 +/- 4.21 micromols/L; p = 0.22. CONCLUSIONS We conclude that Vitamin C therapy in patients with BEN on HD significantly increases the Antioxidant Capacity of Water soluble substances (ACW) as compared to controls and could be used to counter oxidative stress in patients with ESRD.

Abstract
UNLABELLED HCV is an important cause of renal disease. Taal and Brenner have identified risk factors for CKD and have suggested that these risk factors be incorporated into a renal risk score analogous to the Framingham cardiovascular score. Given the high HCV-renal disease comorbidity, we sought to assess risk factors for CKD in patients with HCV chronic hepatitis. METHODS One hundred-seventeen patients with HCV chronic hepatitis (mean age: 50.68 +/- 9.14 years; 86 female and 31 male) hospitalized in the Department of Hepatology during 2009 were enrolled into the study. All patients were assessed for the risk factors for CKD proposed by Taal and Brenner: albuminuria, diabetes mellitus, hypertension, obesity, anemia, hypercholesterolemia, hypertriglyceridemia, nephrotoxins, primary renal disease, associated urological disorder, cardiovascular disease and family history of CKD. Renal function (GFR-CKD-Epi) was also evaluated. STATISTICAL ANALYSIS Pearson's correlation coefficient and Odds Ratio (OR) was performed using SPSS17 and Epi 3.2.2. RESULTS The prevalence of albuminuria was 21.36%, of hypertension was 20.51%, of obesity was 21.36%, and hypercholesterolemia was present in 41.02% of the cases. Renal function was as follows: 10.25% (12/117) of the patients had a GFR < 60 mL/min/1.73 sqm.; 64.95% (76/117) of the patients had a GFR between 60-89 mL/min/1.73 sqm.; and 24.78% (29/117) had a GFR > or = 90 mL/min/1.73 sqm. CONCLUSIONS Our study shows that HCV chronic hepatitis is associated with renal function impairment in a high percentage of patients. Prominent risk factors for CKD are present in these patients, such as albuminuria, hypertension, obesity, and hypercholesterolemia, which need to be actively searched and addressed therapeutically.

Abstract
UNLABELLED CKD patients present deficient elimination of potassium. Ambulatory treatment with hypotensors, mainly angiotensin-renin system inhibitors, can be associated in these patients with potassium retention and risk of hyperkalemia. In pre-dialysis stage-5 CKD patients, the use of medication accompanied by hyperkalemia increases risks of developing it. Using diuretics like spironolactone also increases this risk. Serum potassium can also increase in case of inappropriate consumption of potassium-rich food (bananas). Since ambulatory care does not always rigorously control hyperkalemia in CKD patients we consider it is useful to screen patients when they are referred to dialysis services. The screening can reflect the management of ambulatory CKD patients under treatment with ACE-I and ARB hypotensors. We remark that beta-blockers are attributed a (limited) role in increasing the values of serum K. MATERIAL AND METHOD We studied a group of 477 stage-5 CKD patients referred for dialysis to The Dialysis Centre of the Emergency County Hospital Timişoara. The average age of the patients was 57.41 +/- 14.26 years. 260 were males and 217 females. All were stage-5 CKD with GFR < 15 mL/min/1.73 m2, with a group average value of eGFR of 5.72 +/- 2.81 mL/min/1.73m2. Our investigations showed hypokalemia in 14 patients (2.93%). Hyperkalemia was found in 179 patients. Of these, 124 had mild hyperkalemia (5.5-6.4 mEq/L), 45 patients had medium hyperkalemia (6.5-7.5 mEq/L) and 10 (2.09%) had severe hyperkalemia (K > 7.5 mEq/L). DISCUSSION Hyperkalemia was more frequent in patients who had been treated with blockers of the renin-angiotensin system than in patients who had used other hypotensors or who had not needed hypotensors and had not taken diuretics. Severe hyperkalemia (K > 7.5 mEq/L) was present both in patients treated with blockers of the renin-angiotensin system and in those treated with other hypotensors and in 1 case without hypotensor or diuretic treatment. 2 cases treated with blockers of the renin-angiotensin-aldosterone system with severe hyperpotassemia associated antialdosteronic diuretics, cumulating hyperpotassemic effects. Diuretic treatments with loop diuretics influenced the values of serum K of most patients. Hyperkalemia represents an important problem in nephrology because of the risks it induces in the treatment ofpre-dialysis CKD patients and it requires attentive monitoring.

Abstract
A case of strongyloidiasis in a patient with membranoproliferative glomerulonephritis is reported. In our patient, strongyloidiasis evolved latently and became overt after corticotherapy, and it turned to be a very severe outcome and life-threatening complications, hyperinfection syndrome and upper digestive tract hemorrhage. Besides its well-known complications, steroid therapy may provide real surprises. The association of this therapy with strongyloidiasis may turn an undiagnosed inactive, chronic form of the disease into an active form within the framework of a hyperinfection syndrome which might lead to death. In our case, the diagnosis of strongyloidiasis was established only after duodenal biopsy was performed for upper digestive tract hemorrhage, which revealed the parasite. It should be underlined that under corticotherapy, the patient evolved favorably with regard to glomerular disease, while strongyloidiasis worsened. The outcome was positive after the patient was treated with albendazole and ivermectin. The diagnosis of strongyloidiasis is sometimes difficult to establish due to the fact that eosinophilia may be absent, while commonly utilized stool examinations may be negative. By analyzing our case, it may be assumed that the immune mechanisms involved in strongyloidiasis do not activate the glomerular nephropathy. On the contrary, these mechanisms seem to have an immunosuppressive effect. The "hygienic hypothesis" also needs to be considered. While on corticotherapy, patients with glomerulonephritis need immunologic and parasitologic monitoring. This is important for other immunodepressing diseases and for immunosuppressive drugs. If the patient has originated in a mining area, as is the case with our patient, or in endemic areas, this monitoring becomes mandatory. The case reflects the complexity of the interrelation between the immune mechanisms in glomerulonephritis and those in parasitic diseases, strongyloidiasis in our case.

Abstract
Colorectal cancer represents the third cause of cancer. Since its detection in due time is important resolution, appropriate monitoring is mandatory. The present study deals with the relationship between colorectal cancer and renal function, as well as other associated risk factors. Chronic kidney disease (CKD) represents a risk factor of cancer, both in non-dialysed patients and especially in dialysed patients and in patients with renal transplant. It can get aggravated with cancer in general and particularly with colorectal cancer, partly related to the toxins that cannot be appropriately eliminated because of renal functional disturbances. At the same time, immunosuppressive therapy used for treating glomerular or secondary nephropathies represents an important risk factor of cancer. Some patients with colorectal cancer were found to present also impaired renal function, a fact whose significance is still little known. The object of the present paper is an analysis of the case records of a clinic of gastroenterology on the relationship between colorectal cancer and renal functional impairment. We found in the patients with colorectal cancer under study a glomerular filtration rate (GFR calculated with the EPI formula) of < 60 ml/min/1.73m2 in 31/180 patients, respectively 17.22% of the cases, a value that is similar to that in specialised literature. We also analysed associated risk factors that could be related to renal function impairment in these patients: age, gender, anaemia, diabetes mellitus and hypertension. These could represent, together with the colorectal cancer of the investigated patients, risk factors affecting on the one hand renal function, and on the other hand, potentially increasing the risk of cancer. Correction of these risk factors would have beneficial effects on patients. The relationship between renal functional impairment, respectively CKD, and colorectal cancer is to be regarded from the point of view of complex reciprocity: the impairment of the renal function is a factor of risk of colorectal cancer and colorectal cancer can influence renal function of these patients. This report of reciprocity based on important pathogenic mechanisms also interrelates with factors of risk consecutive to both renal function impairment and colorectal cancer.

Abstract
The paper highlights the importance of tubular lesions of the solitary kidney (SK), identified and monitored by means of urinary biomarkers, mainly N-acetyl-beta-D-glucosaminidase (NAG), albumin, alpha 1-, and beta 2-microglobulin. It is considered that the assessment of a SK should be performed with four and not three parameters as it was usually done until recently: renal function, proteinuria and blood pressure (BP), to which biomarkers should be added. The solitary kidney can result after nephrectomy for kidney transplantation. In some countries living kidney donors represent the only option for performing kidney transplantation. The SK in living donors has generally a good evolution, although sometimes renal injury manifested by proteinuria, arterial hypertension (AH), or diminution of renal function does occur. Therefore, living donors require attentive monitoring. The SK is considered to have a good evolution (even in donors), in spite of alterations of the above-mentioned clinical and biological parameters. The very infrequent cases who evolve progressively towards renal failure are not predictable, which requires monitoring of all persons with a SK. The SK represents a special situation in case of association with a disease affecting the kidney, such as urinary tract infection (UTI), diabetes mellitus, or systemic lupus erythematosus (SLE). Pregnancy occurring in a person with a SK also needs attentive follow-up. Pregnancy associated diseases, such as preeclampsia occurring in patients with a SK, impose appropriate therapeutic behaviour. The SK remains a particular entity in nephrology which needs to be carefully monitored.

Abstract
BACKGROUND Renal dysfunction is a major determinant of the Model of End-stage Liver Disease (MELD) score. The implementation of the MELD score has shifted allocation of livers to patients with renal dysfunction. OBJECTIVES The aim of our study was the assessment of estimated Glomerular Filtration Rate (eGFR) by the Modification of Diet in Renal Disease 4 (MDRD4) method in patients with HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis (CH) caused by these viruses to detect any differences in renal function among these diseases. PATIENTS AND METHODS We performed a cross-sectional analysis of all consecutive patients with HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis caused by these viruses hospitalized during a 4 year period in the Gastroenterology and Hepatology department of the Emergency County Hospital Timisoara, Romania. The eGFR was assessed by the MDRD4 method. Statistical analysis (unpaired t-test, ANOVA, Chi Square test) was performed using OpenEpi 2.3.1. RESULTS HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the GFR. The eGFR was higher in patients with HBV chronic hepatitis than in patients with HCV chronic hepatitis (P < 0.001). Patients with cirrhosis secondary to HBV infection had a higher eGFR than patients with cirrhosis secondary to HCV (P = 0.01). The eGFR of patients with HCV chronic hepatitis was higher than the eGFR of patients with cirrhosis due to this virus (P < 0.001). CONCLUSIONS Functional renal impairment in diseases caused by HCV was more important than in diseases caused by HBV. The eGFR was statistically lower in cirrhosis secondary to HCV than in HCV chronic hepatitis.

Abstract
The solitary kidney (SK) is of special interest for practitioners because of the reduced number of nephrons as compared to persons who have 2 kidneys. It undergoes adaptive phenomena of hypertrophy and hyperfiltration that allow long-term evolution, but pathological situations might occur in the remnant kidney. In some persons with a SK, the adaptive phenomena can be associated with proteinuria, arterial hypertension (AH) and diminished Glomerular Filtration Rate (GFR). In very rare situations, diminution of renal function in patients with a SK can progress to end-stage renal disease (ESRD) and, totally exceptionally, it requires renal replacement therapy. The SK can be congenital or acquired. At present patients with a SK address themselves more and more frequently to nephrology services which monitor the evolution of both the congenital and the surgically acquired SK. The congenital SK possesses a higher number of nephrons (75%, as compared to 2 functional kidneys in a healthy person) than the surgically acquired SK - 50% nephrons. This makes adaptive phenomena differ. Secondary lesions sometimes appear later in case of the congenital SK. In other situations, no significant differences between the evolution of the congenital or acquired SK are registered. The congenital solitary kidney is often associated with congenital abnormalities of the kidney and of the urinary tract (CAKUT). This association increases the risk for chronic kidney disease and for evolution towards chronic renal failure. The congenital SK is also often associated with gynaecological and other abnormalities. The acquired solitary kidney can be due to nephrectomy on a pathological kidney which could not be conservatively treated or due to donation of a kidney for renal transplantation. The SK itself sometimes requires partial nephrectomy intervention, for example sparing surgery. Although the evolution is in most cases favorable, it requires attentive monitoring.

Abstract
Recently, chronic Aristolochia poisoning was found responsible for the aetiology of Balkan endemic nephropathy (BEN) in Croatia, Serbia, and Bosnia, and diet was the likely route of exposure to aristolochic acid (AA). BEN, often associated with an increased incidence of upper urinary tract carcinoma (UUC), also affects residents of certain rural villages in Romania. AA is a nephrotoxin and human carcinogen that forms DNA adducts after metabolic activation, which induce characteristic TP53 mutations in urothelial tumours. Here we present the first evidence linking AA exposure to UUC in residents of an endemic region in the Romanian Mehedinti County. DNA was extracted from kidney and tumour tissue of seven patients who underwent nephroureterectomy for UUC and resided in BEN villages (endemic group). Five patients with UUC from nonendemic villages served as controls. AA-DNA adducts (7-(deoxyadenosin-N(6) -yl)-aristolactam I), established biomarkers of AA exposure, were identified by (32)P-postlabelling in renal DNA of six patients from the endemic group and in one of the nonendemic group (adduct levels ranged from 0.3 to 6.5 adducts per 10(8) nucleotides). Additionally, an A to T transversion in TP53, a base substitution characteristic of AA mutagenic activity was found in urothelial tumour DNA of one patient from the endemic group. Our results provide a molecular link to the cause of urothelial tumours in BEN regions of Romania indicating that AA is the common aetiological agent for BEN across its numerous geographical foci.
