Abstract
OBJECTIVES To compare health-related quality of life (HRQOL), cost-effectiveness, and survival among different types of urinary diversion (UD) utilized after radical cystectomy (RC) for bladder cancer with consideration of the unique economic and cultural context in Iran. PATIENTS AND METHODS In this retrospective study, we examined all patients who underwent RC from May 2017 to December 2021 at two specialized centers by the same surgical team. Patients were grouped based on their UD. Post-surgical HRQOL (obtained from EORTC QLQ-C30 and QLQBLM-30), financial burden, surgical complications, and survival were compared. Kruskal-Wallis H test, One-way ANOVA, and Kaplan-Meier analyses were utilized; accordingly. RESULTS AND LIMITATIONS In total 187 patients were identified-orthotopic neobladder (ONB) (N = 75), ileal conduit (IC) (N = 57), and cutaneous ureterostomy (CU) (N = 55)-and were followed for a median 17.5 (Interquartile range: 7.0, 47.0) months. ONB was associated with better HRQOL, especially in the domains addressing physical, role and social functioning (p = 0.003, 0.011, 0.045) as well as better body image (p < 0.001), lower short- and long-term financial burden (p = 0.034 and <0.001, respectively), marginally lower complication rate (p = 0.049), and better 5-year overall survival (p < 0.001), in comparison with other UDs. Patients who underwent CU had the lowest HRQOL and worst survival. Limitations were retrospective design and possibility of selection bias. CONCLUSIONS In this first study that assesses a Middle Eastern collective; ONB seems to be the UD of choice with regard to HRQOL and economic burden when there is no contraindication.

Abstract
OBJECTIVES This systematic review and meta-analysis aimed to investigate the prevalence of postmortem kidney histopathologic features of patients with coronavirus disease 2019 (COVID-19) in addition to the rate of renal tropism in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS We searched Web of Science, PubMed, Embase, and Scopus up to September 2022 to identify eligible studies. A random-effects model was used to estimate the pooled prevalence. Cochran Q test and Higgins I2 were used to assess evidence of heterogeneity. RESULTS In total, 39 studies were included in the systematic review. The meta-analysis included 35 studies consisting of a total of 954 patients, with an average age of 67.1 years. The pooled prevalence of acute tubular injury (ATI)-related changes was the predominant finding (85% [95% confidence interval, 71%-95%]), followed by arteriosclerosis (80%), vascular congestion (66%), and glomerulosclerosis (40%). Endotheliitis (7%), fibrin microthrombi (12%), focal segmental glomerulosclerosis (1%), and calcium crystal deposits (1%) were seen in a smaller number of autopsies. The overall average rate of virus detection was 47.79% in the pooled data of 21 studies (272 samples). CONCLUSIONS The main finding-ATI-correlated to clinical COVID-19-associated acute kidney injury. The presence of SARS-CoV-2 in kidney samples in addition to vascular lesions in kidneys can be linked to direct kidney invasion by the virus.

Abstract
PURPOSE Concomitant kidney diseases raise the mortality rate due to the SARS-CoV-2 virus as an independent factor. Although a qualitative PCR test's result is sufficient for diagnosis, Cycle threshold value may present relevant information to the physicians in providing faster treatment in patients with chronic conditions, including kidney diseases, to prevent morbidity and subsequent mortality. Thus, the present study was conducted to determine the relationship between the Cycle threshold value and clinical outcomes in renal patients with the coronavirus 2019. METHODS This retrospective study was conducted on renal patients with the coronavirus 2019 infection admitted to Labbafinejad Hospital in Tehran, the capital of Iran, within a period of one year, from late February 2020 to February 2021. Data were collected per the prepared checklist. Cycle threshold values were measured by performing PCR on nasopharynx and oropharynx swab samples of patients. RESULTS According to the adjusted analysis, having high viral load increased the odds of in-hospital mortality (aOR = 11.65, 95% CI 3.93-34.54), ICU admission (aOR = 5.49, 95% CI 2.16-13.97), and invasive ventilation (aOR = 7.18, 95% CI 2.61-19.74). Having high viral load also increased the odds of O2 therapy (aOR = 3.08, 95% CI 0.79-12.01), although the difference was not statistically significant (P = 0.105). CONCLUSION Cycle threshold value was a significant predictor of mortality in renal patients. Nevertheless, further studies are required on how to render optimal use of the Cycle threshold value, given that the quality of the test sample and the different groups of patients under study affect the effectiveness of this marker in predicting disease severity.

Abstract
Objectives To assess the efficacy and safety of T-DM1, as an anti-HER2 antibody-drug conjugate (ADC), alone and in combination with two platinum-based chemotherapy regimens in patient-derived xenografts (PDXs) of muscle-invasive bladder cancer (MIBC) established in immunodeficient mice. Materials and Methods After treatment initiation, tumor size was measured twice a week. Percent of tumor growth inhibition (TGI) and tumor response rates were calculated as efficacy endpoints. To evaluate treatment toxicity, relative body weight (RBW) was calculated for each group. For comparison of TGIs between treatment groups, the Kruskal-Wallis test was used. Also, the significance of the overall response (OR) rate between placebo groups with treatment groups was analyzed using Fisher's exact test. Immunohistochemistry and fluorescence in situ hybridization techniques were used to evaluate the level of HER2 expression. Results Our data showed that T-DM1 alone induced a moderate antitumor activity. While chemotherapy regimens induced a slight TGI when administered alone, interestingly, they showed strong antitumor activity when administered combined with T-DM1. The OR rates were higher when T-DM1 was combined with chemotherapy regimens than T-DM1 alone. When compared with the placebo group, the OR rates of combination groups were statistically significant. Our data also showed that the administered dose of each drug was well tolerated in mice. Conclusion The combination of T-DM1 and platinum-based chemotherapy may represent a new treatment option for bladder tumors with even low HER2 expression, and could also provide substantial novel insight into tackling the challenges of MIBC management.

Abstract
Objective(s): Patient-derived xenograft (PDX) models have become a valuable tool to evaluate chemotherapeutics and investigate personalized cancer treatment options. The role of PDXs in the study of bladder cancer, especially for improvement of novel targeted therapies, continues to expand. In this study, we aimed to establish autochthonous PDX models of muscle-invasive bladder cancer (MIBC) to provide a useful tool to conduct research on personalized therapy. Materials and Methods: Tumors from MIBC patients undergoing radical cystectomy were subcutaneously transplanted into immunodeficient mice. The tumor size was measured by a caliper twice a week for up to five months. After the first growth in mice, they were serially passaged. Hematoxylin and eosin (H&E) staining and immunohistochemistry (IHC) of 11 markers (Ki67, P63, GATA3, KRT5/6, KRT20, E-cadherin, 34βE12, PD-L1, EGFR, Nectin4, and HER2) were used to evaluate phenotype maintenance of original tumors. Results: From 10 MIBC patients, two PDX models (P8X20 and P8X26) were successfully established (20% success rate). These models mostly retained primary tumor characteristics including histology, morphology, and molecular nature of the original cancer tissues. IHC analysis showed that the expression level of 7 markers for the model P8X20, and 8 markers for the model P8X26 was exactly similar between the patient tumor and the next generations. Conclusion: We developed the first autochthonous PDX models of MIBC in Iran. Our data suggested that the established MIBC PDX models reserved mostly histopathological characteristics of primary cancer and could provide a new tool to evaluate novel biomarkers, therapeutic targets, and drug combinations.

Abstract
INTRODUCTION To study the prevalence of vitamin D deficiency in kidney stone formers and its predisposing factors and to assess the relationship between serum 25-Hydroxyvitamin D and urine metabolites. METHODS Kidney stone formers were selected from the records of the kidney stone prevention clinic in Labbafinejad hospital, Tehran, Iran. Vitamin D deficiency was defined as 25-Hydroxyvitamin D < 20 ng/mL. The association between vitamin D deficiency and predisposing factors, serum, and urine metabolites was evaluated. RESULTS In 1005 patients (66.4% men and 33.6% women), the prevalence of vitamin D deficiency was 44.8%. Vitamin D deficiency was more prevalent in patients under 50 years (P < .001) and patients with hyperparathyroidism (P < .05). The lowest prevalence of hyperparathyroidism was in the 25-Hydroxyvitamin D range of 40 to 49.9 ng/mL, followed by the range of 30 to 39.9 and 20 to 29.9 ng/mL. Patients with vitamin D deficiency had lower serum creatinine (P < .02), lower 24-hour urine calcium (P < .01), and lower 24-hour urine oxalate (P < .05). CONCLUSION Iranian kidney stone formers have a relatively high prevalence of vitamin D deficiency. Our population seems to have different predisposing factors for vitamin D deficiency, i.e., higher prevalence among younger patients and no association between obesity and gender with vitamin D status. According to the parathyroid hormone, the favorable serum 25-Hydroxyvitamin D level was 20 to 49.9 ng/mL in our kidney stone formers.

Abstract
Antibody-drug conjugate therapy has attracted considerable attention in recent years. Since the selection of appropriate targets is a critical aspect of antibody-drug conjugate research and development, a big data research for discovery of candidate targets per tumor type is outstanding and of high interest. Thus, the purpose of this study was to identify and prioritize candidate antibody-drug conjugate targets with translational potential across common types of cancer by mining the Human Protein Atlas, as a unique big data resource. To perform a multifaceted screening process, XML and TSV files including immunohistochemistry expression data for 45 normal tissues and 20 tumor types were downloaded from the Human Protein Atlas website. For genes without high protein expression across critical normal tissues, a quasi H-score (range, 0-300) was computed per tumor type. All genes with a quasi H - score ≥ 150 were extracted. Of these, genes with cell surface localization were selected and included in a multilevel validation process. Among 19670 genes that encode proteins, 5520 membrane protein-coding genes were included in this study. During a multistep data mining procedure, 332 potential targets were identified based on the level of the protein expression across critical normal tissues and 20 tumor types. After validation, 23 cell surface proteins were identified and prioritized as candidate antibody-drug conjugate targets of which two have interestingly been approved by the FDA for use in solid tumors, one has been approved for lymphoma, and four have currently been entered in clinical trials. In conclusion, we identified and prioritized several candidate targets with translational potential, which may yield new clinically effective and safe antibody-drug conjugates. This large-scale antibody-based proteomic study allows us to go beyond the RNA-seq studies, facilitates bench-to-clinic research of targeted anticancer therapeutics, and offers valuable insights into the development of new antibody-drug conjugates.

Abstract
Primary hyperoxaluria is a rare congenital autosomal recessive disorder disrupting the glyoxylate metabolism pathway in the liver. Type1 primary hyperoxaluria is caused by a deficiency in a specific liver enzyme namely, alanine glyoxylate-aminotransferase which catalyzes the conversion of glyoxylate to glycine. By the absence of this enzyme, glyoxylate is converted to oxalate and high oxalate level causes deposition of insoluble calcium oxalate crystals in different organs specifically kidneys. The disease usually manifested by recurrent nephrolithiasis and/or nephrocalcinosis leads to renal failure. This report describes an end-stage renal disease case of a 36-year-old Iranian woman without any history of nephrolithiasis who underwent kidney transplantation. She developed an early onset transplant kidney failure. The patient underwent kidney biopsy, which revealed oxalate nephropathy, accordingly the genetic study confirmed diagnosis of primary hyperoxaluria. This rare case shows how type 1 primary hyperoxaluria can develop after kidney transplantation without having any manifestation prior to transplantation

Abstract
Human cytomegalovirus (HCMV), as a ubiquitous and opportunistic virus, is a matter for consideration in broad-spectrum diseases, specifically in immunocompromised individuals. In recent decades, many studies that have evaluated the role of HCMV in inflammation and malignancies, especially in high-grade gliomas, have reported inconsistent results. Thus, this study was conducted to analyze 97 primary gliomas for human CMV UL83 gene and protein through TaqMan real-time polymerase chain reaction and immunohistochemistry, respectively. The results were positive for the UL83 gene and pp65 protein in 71% and 24% of samples, respectively. The frequency of HCMV was significantly higher in glioblastomas than other glioma grades (P < .01 and P < .05 for the UL83 gene and protein, respectively). In addition, the association between the prevalence of HCMV and aging strengthened the virus reactivation hypothesis in gliomas. In conclusion, a high frequency of HCMV infection was found in gliomas that correlated with tumor aggressiveness and age. This study recommends a thorough investigation to determine HCMV infection in gliomas to improve the existing knowledge of its role in glial tumors, its prognostic value, and possible efficient antiviral target therapy.

Abstract
Introduction: Focal segmental glomerulosclerosis (FSGS), the most common primary glomerular disease, is a diverse clinical entity that occurs after podocyte injury. Although numerous studies have suggested molecular pathways responsible for the development of FSGS, many still remain unknown about its pathogenic mechanisms. Two important pathways were predicted as candidates for the pathogenesis of FSGS in our previous in silico analysis, whom we aim to confirm experimentally in the present study. Methods: The expression levels of 4 enzyme genes that are representative of "chondroitin sulfate degradation" and "eicosanoid metabolism" pathways were investigated in the urinary sediments of biopsy-proven FSGS patients and healthy subjects using real-time polymerase chain reaction (RT-PCR). These target genes were arylsulfatase, hexosaminidase, cyclooxygenase-2 (COX-2), and prostaglandin I2 synthase. The patients were sub-divided into 2 groups based on the range of proteinuria and glomerular filtration rate and were compared for variation in the expression of target genes. Correlation of target genes with clinical and pathological characteristics of the disease was calculated and receiver operating characteristic (ROC) analysis was performed. Results: A combined panel of arylsulfatase, hexosaminidase, and COX-2 improved the diagnosis of FSGS by 76%. Hexosaminidase was correlated with the level of proteinuria, while COX-2 was correlated with interstitial inflammation and serum creatinine level in the disease group. Conclusion: Our data supported the implication of these target genes and pathways in the pathogenesis of FSGS. In addition, these genes can be considered as non-invasive biomarkers for FSGS.

Abstract
Genitourinary hemangiomas are very rare. To our knowledge few cases of female urethral hemangiomas have been reported and presenting cases are the first reports in Iran.They should be considered as differential diagnosis of any female patient with microscopic or gross hematuria or bloody urethral discharge, especially when other parts of urinary system are radiologically intact. Thorough physical examination of genital area is highly recommended in order not to miss any urethral lesions. Herein we report two cases of female urethral cavernous hemangioma, their management and a review of literature.

Abstract
PURPOSE Sphingosine 1 phosphate (S1P), S1P receptors (S1PRs) and their signaling pathways play an important role in the fate of cancer cells. The expression pattern of S1PR subtypes (S1PR1-S1PR5) may alter in cancer development stages, depending on the origin and the pathologic features of tumors. The present study aimed to examine the relationship between plasma S1P levels and the expression of S1PR subtypes in bladder tumors. METHODS/PATIENTS These changes were evaluated in terms of the pathologic grades and stages of human bladder cancer samples. For this, tumor biopsies from 41 new bladder cancer patients as well as 26 normal-looking bladder tissues were collected and processed for immunohistochemistry (IHC) and quantitative real-time RT-PCR of S1PR subtypes. Plasma S1P level was measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS The results show that tissue S1PR1, S1PR2 and S1PR3 are over-expressed in all tumors regardless of their pathological grade (~ 3, ~ 6 and ~ 104 folds, respectively). These results were corroborated by IHC data showing accumulation of S1PR subtypes 1 and 2 in the tissues. Plasma S1P in the plasma samples from patients was in the range of control samples (Controls; 256 ± 47; patients, 270 ± 41). CONCLUSIONS Overexpression of S1PR1, S1PR2 and S1PR3 in bladder tumor biopsies which were corroborated with the pathological grades and stages may suggest that S1PR profile in tumor biopsies is a promising marker in the diagnosis of bladder carcinoma.

Abstract
The aim of this study was to characterize virulence factors and antibiotic resistance patterns in E. faecalis strains obtained from community-acquired urinary tract infections. A total of 70 E. faecalis isolates from Labbafinejad Hospital in Tehran were collected. Antibiotic resistance and virulence determinants were examined by phenotypic and molecular methods. Among 70 E. faecalis isolates, efba (97.1%), ace (95.7%), and gelE (94.3%) were the most prevalent virulence genes. The most common antibiotic resistance pattern was tetracycline (88.6%) and minocycline (87.1%). Multi-drug resistant phenotype was detected among 10% of them. Our results showed capability of E. faecalis strains for infection of the urinary tract in community. Involvement of virulence determinants in the pathogenesis of community acquired E. faecalis strains was proposed due to their high prevalence rates. Food producing animals were proposed as their environmental reservoirs, due to dominance of tetracycline resistance phenotype among them.

Abstract
Complement C3 glomerulopathy refers to a disease process in which abnormal control of complement activation or degradation results in predominant C3 fragment deposition within the glomerulus and causes glomerular damage. Abnormal control of the complement alternative pathway is a well-established risk factor for the occurrence of C3 glomerulonephritis. It is the first reported case in Iran with multiple mutations in complement factor H, with one of these mutations we have expected in hemolytic uremic syndrome rather than C3 glomerulopathy Genetic analysis showed that the molecular abnormalities of factor H led to complement factor H malfunction that were polymorphous and not restricted to the C-terminal domains of the protein.

Abstract
BACKGROUND Asthma is one of the important chronic diseases. The asthma prevalence is increasing in last decades. Despite the presence of good controller drugs like corticosteroids, about 60% of asthmatic patients use alternative medicine. This study was done to determine the effectiveness of Tregonella foenum graceum (fenugreek) seeds in mild asthma. METHODS It is a double blind trial with placebo effect. One of the ancient prescriptions from Persian Medicine was selected. The participants were divided to three groups randomly. On group received fenugreek syrup one received honey syrup and the third received placebo. Duration of treatment was 4 weeks. Quality of life, Lung function tests and IL-4 levels were evaluated before and after treatment. RESULTS From 90 participants to study 79 completed the process. After study there was significant increase in quality of the life and lung function tests and IL-4 levels in fenugreek and honey groups. CONCLUSION FEV1 level was improved more than 10% in fenugreek group. Treatment was well tolerated. No serious side effects were reported during the study. The aqueous extract of fenugreek seeds appears to be effective and safe in treatment of mild asthma.Trial registration The study was recorded with the Iranian Registry of Clinical trials [http://www.irci.ir], registration code: IRCT2016011325991N1.

Abstract
CONTEXT Acute kidney injury (AKI) is a common complication after kidney transplantation (KT), especially in recipients from deceased donors. Urinary neutrophil gelatinase-associated lipocalin (u-NGAL) is an early and sensitive marker of AKI after transplantation. OBJECTIVES We assessed the renoprotective effect of N-acetylcysteine (NAC) on u-NGAL levels as an early prognostic marker of graft function immediately after transplantation. MATERIALS AND METHODS A double-blind, randomized, placebo-controlled trial was conducted on 70 deceased-donor KT recipients ( www.irct.ir , trial registration number: IRCT2014090214693N4). Patients received 600 mg oral NAC or placebo twice daily from day 0 to 5 and urine samples were taken before, and on the first and fifth days after transplantation. U-NGAL and early graft function were compared between the two groups. RESULTS NAC significantly reduced u-NGAL levels compared to placebo (p value = 0.02), while improvement in early graft function with NAC did not reach statistical significance. CONCLUSIONS This study showed that NAC administration in deceased-donor KT recipients can reduce tubular kidney injury, evidenced by u-NGAL measurements. Improvement in early graft function needs a larger sample size to reach a statistical conclusion.

Abstract
The severity of IgA nephropathy (IgAN), the most common primary glomerulonephritis, is judged on the basis of histologic and clinical features. A limited number of studies have considered molecular signature of IgAN for this issue, and no reliable biomarkers have been presented non-invasively for use in patient evaluations. This study aims to identify metabolite markers excreted in the urine and impaired pathways that are associated with a known marker of severity (proteinuria) to predict mild and severe stages of IgAN. Urine samples were analysed using nuclear magnetic resonance from biopsy-proven IgAN patients at mild and severe stages. Multivariate statistical analysis and pathway analysis were performed. The most changed metabolites were acetoacetate, hypotaurine, homocysteine, L-kynurenine and phenylalanine. Nine metabolites were positively correlated with proteinuria, including mesaconic acid, trans-cinnamic acid, fumaric acid, 5-thymidylic acid, anthranilic acid, indole, deoxyguanosine triphosphate, 13-cis-retinoic acid and nicotinamide riboside, while three metabolites were negatively correlated with proteinuria including acetoacetate, hypotaurine and hexanal. 'Phenylalanine metabolism' was the most significant pathway which was impaired in severe stage in comparison to mild stage of IgAN. This study indicates that nuclear magnetic resonance is a versatile technique that is capable of detecting metabolite biomarkers in combination with advanced multivariate statistical analysis.

Abstract
BACKGROUND While acute rejection and early graft loss rates have decreased substantially over the past four decades, progressive chronic allograft dysfunction (CAD) still remains a common cause of late graft loss in kidney transplant recipients. OBJECTIVE This study was conducted to investigate the percentage of natural killer (NK) cell subsets and IL-2, 15 and 18 genes expression in two groups of CAD and well-function graft (WFG) recipients. METHODS 30 renal allograft recipients with biopsy-proven interstitial fibrosis/tubular atrophy (IF/TA) and impaired renal function, and 30 sex- and age-matched WFG patients were enrolled in this study. The percentage of NK cell subsets including NK CD56bright and NK CD56dim cells were determined by flowcytometry; IL-2, IL-15, and IL-18 genes expressions were assessed by real-time PCR. RESULTS Compared to WFG patients, there was a significant (p<0.05) increase in the percentage of NK CD56bright cells in CAD patients. However, the difference in percentage of NK CD56dim cells or CD56dim/CD56bright ratio between the studied groups was not significant. In addition, IL-2, 15 and 18 genes expressions were almost similar in CAD and WFG patients. CONCLUSION We found higher percentages of NK CD56bright subset in kidney transplant recipients with CAD without considerable changes in related cytokines' gene expression, suggesting a possible defect of NK cells maturation in these patients.

Abstract
Focal segmental glomerulosclerosis (FSGS) is a common glomerulonephritis, and its rates of occurrence are increasing worldwide. Proteinuria is a clinical defining feature of FSGS which correlates with the severity of podocyte injury in patients with nephrotic-range protein excretion. Metabolite biomarkers corresponding with the level of proteinuria could be considered as non-invasive complementary prognostic factors to proteinuria. The urine samples of 15 patients (n = 6 women and n = 9 men) with biopsy-proven FSGS were collected and subjected to nuclear magnetic resonance (NMR) analysis for metabolite profiling. Multivariate statistical analyses, including principal component analysis and orthogonal projection to latent structure discriminant analysis, were applied to construct a predictive model based on patients with proteinuria >3000 mg/day and <3000 mg/day. In addition, random forest was performed to predict differential metabolites, and pathway analysis was performed to find the defective pathways responsible for proteinuria. Ten metabolites, significant in both statistical methods (orthogonal projection to latent structure discriminant analysis and random forest), were considered as prognostic biomarkers for FSGS: citrulline, dimethylamine, proline, acetoacetate, alpha-ketoisovaleric acid, valine, isobutyrate, D-Palmitylcarnitine, histidine, and N-methylnicotinamide. Pathway analysis revealed impairment of the branched-chain amino acid degradation pathways in patients with massive proteinuria. This study shows that metabolomics can reveal the molecular changes corresponding with disease progression in patients with FSGS and provide a new insight for pathogenic pathways.

Abstract
Background: The most common malignancy in the urinary system has been bladder cancer and the most predominant histologic subtype has been transitional cell carcinoma (TCC). There were many molecular risk factors, related with poor prognosis. One of these factors was expression of epidermal growth factor receptor (EGFR). Objectives: The aim of this study was to evaluate the prevalence of the epidermal growth factor receptor in transitional cell carcinoma of bladder and its relationship with other prognostic factors. Patients and Methods: This analytic descriptive study has performed with 61 patients with TCC of bladder after radical cystectomy whom have been hospitalized in Labbafinejad hospital in Tehran, Iran between 2007 and 2010. We have used Chi-square and t-test to analyze our data samples. Results: Records of 61 patients have studied. Fifty three of the total samples were positive for EGFR expression (86.9%). Fifty samples of these fifty-three belonged to men and three others were women’s samples (P = 0.46). Among the group with EGFR expression the results were as follows: 25 patients (47.2%) were 60 years old or less and 28 patients (52.8%) were older than 60 (P = 0.023), 16 patients (30.2%) had invasion to lamina properia, and the rest of them had invasion to deeper layers (P = 0.56). For most patients we could not determine the invasion of tumoral cells into the lymph nodes (Nx) (P = 0.067). Thirty four patients (64.2%) had not lymphovascular invasion (P = 0.44) and in forty three of patients (81.1%), perineural invasion have not seen (P = 0.23). Finally, 36 patients (67.9%) were grade 3 (P = 0.27). Conclusions: In this study we have concluded that most patients had EGFR positive expression. Also, except for the age, there was not any significant relation between expression of EGFR and the other prognostic factors such as, gender, invasion of the tumor into the layers, involving the lymph nodes, lymphovascular or perineural invasion, and grading.

Abstract
INTRODUCTION In 2009, the Oxford classification of immunoglobulin A (IgA) nephropathy was proposed by the working group of the International IgA Nephropathy Network and Renal Pathology Society. It established specific pathologic features that predict the risk of progression of disease. This study aimed to evaluate the interobserver reproducibility of the Oxford classification of IgA nephropathy between Iranian nephropathologists. MATERIALS AND METHODS We included 100 patients with primary IgA nephropathy diagnosed between 2001 and 2011. Histologic slides were circulated among 4 pathologists. A score sheet was answered by each individual pathologist for each biopsy, according to the instruction of the Oxford classification. Reproducibility was determined for each variable, using intraclass correlation coefficient (ICC). RESULTS The ICC values calculated for each major category of the Oxford classification were as follows: the highest score of 0.94 for tubular atrophy and interstitial fibrosis; 0.8 for glomerular basement membrane duplication, extracapillary proliferation, and segmental endocapillary proliferation; and 0.1 to 0.3 for arterial lesions, especially for hyalinosis of arterioles and intimal thickening of arcuate vessels and interlobar arteries. CONCLUSIONS The Oxford classification of IgA nephropathy is a useful tool and evidenced-based method with high interobserver reproducibility in pathology reporting. Our data suggest that Oxford classification may be used as a model for classification of other renal pathologies in the future.

Abstract
PURPOSE To investigate the expression alteration of miR-886-5p in bladder tumors and evaluating its expression level as a potential biomarker in this type of cancer. MATERIALS AND METHODS Formalin-fixed paraffin-embedded (FFPE) samples of bladder tumors belonging to 70 patients whom had been referred to the Shahid Labbafi-Nejad medical center were obtained from the archival collection of pathology department. After RNA extraction and cDNA synthesis, expression levels of miR-886-5p were quantified by a real-time reverse transcription polymerase chain reaction (RT-PCR) approach. RESULTS Our data revealed a significant upregulation (~3 times) of miR-886-5p in high grade bladder tumors, compared to the low grade ones (P < .05). Moreover, its expression level could significantly discriminate noninvasive (Ta, T1) from invasive (T-2T4) tumor stages. CONCLUSION Our data suggests a potential role for miR-886-5p in progression of bladder cancer.

Abstract
INTRODUCTION Immunoglobulin A (IgA) nephropathy, the most common type of glomerulonephritis, is only diagnosed by invasive kidney biopsy. Urine proteome panel might help in noninvasive diagnosis and also better understanding of pathogenesis of IgA nephropathy. MATERIALS AND METHODS Second mid-stream urine samples of 13 patients with biopsy-proven IgA nephropathy and 8 healthy controls were investigated by means of nanoscale liquid chromatography tandem mass spectrometry. Multivariate analysis of quantified label-free proteins was performed by the principal component analysis and partial least squares models. RESULTS A total number of 493 unique proteins were quantified by nanoscale liquid chromatography tandem mass spectrometry, of which 46 proteins were considered as putative biomarkers of IgA nephropathy, after multivariate analysis and additional filter criterion and comparing the patients and the controls. Some of the significant differentially expressed proteins were CD44, glycoprotein 2, vasorin, epidermal growth factor, CLM9, protocadherin, utreoglobin, dipeptidyl peptidase IV, NHL repeat-containing protein 3, and SLAM family member 5. These proteins were related to various involved pathogenic pathways of inflammatory response and complement system. CONCLUSIONS This proteome profile could be utilized in the diagnosis of IgA nephropathy. In addition, providing a noninvasive diagnostic tool, it may shed light on the pathogenesis of IgA nephropathy.

Abstract
INTRODUCTION The genetic variations of co-stimulatory molecules can affect the extent of T cell activity during T-cell mediated immunity, especially in transplant patients. This study aimed to investigate the association of programmed cell death 1 (PDCD1) and programmed cell death 1 ligand 1 (PDCD1LG1) gene polymorphisms with clinical outcome of kidney transplantation. MATERIALS AND METHODS A total of 122 patients with a kidney transplant were included in this retrospective study. Patients were classified into two groups of biopsy-proven acute allograft rejection (AAR) and stable graft function (SGF) during the 5-year follow-up period. Four single nucleotide polymorphisms in PDCD1 and PDCD1LG1 were determined in the groups of patients as well as in 208 healthy control individuals. RESULTS The frequencies of PD-1.3 (+7146 G>A), PD-1.9 (+7625 C>T), PD-L1 (8923 A>C), and PD-L1 (+6777 C>G) genotypes and alleles were not significantly different between the AAR and SGF groups. In comparison with healthy controls, PD-1.9 (+7625 C>T) genotype and T allele were significantly more frequent in all of the patients and in those with SGF. Overall, 27 of 122 kidney allograft recipients experienced delayed graft function, and a higher frequency of PD-1.9 (+7625 C>T) genotype and T allele was observed in this group versus those without delayed graft function. Similarly, a significant high frequency of this genotype was found among the AAR subgroup of patients with delayed graft function. CONCLUSIONS Our results indicate that potentially functional genetic variation in PDCD1 can influence the outcome of kidney transplantation.

Abstract
BACKGROUND Diabetes self-care is a key element in the overall management of diabetes. However, the importance of psychosocial factors for successful disease management is under investigated. This study aimed at exploring the role of coping styles and social support in the relationship between self-care activities and glycated haemoglobin in patients with type 2 diabetes. METHODS One hundred adults (60% female, aged 40-70 years) with type 2 diabetes completed questionnaires assessing self-care activities, coping styles and social support. In addition, a blood test was performed to obtain glycated haemoglobin levels. RESULTS Result showed significant relationships of glycated haemoglobin with self-care activities, coping styles and social support. Regression analysis indicated that social support had a moderating role on the relationship between self-care activities and glycated haemoglobin, such that, at very high levels of social support the association, between Self-Care and HbA1c disappears. CONCLUSIONS Findings indicate that health care providers, within the context of the Iranian social and cultural situation, should pay more attention to psychosocial factors when addressing self-care activities. Delineation of the role of coping styles and social support might be useful for identifying patients in need of particular counselling and support for improving self-care activities and HbA1c levels.

Abstract
BACKGROUND Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF-β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. OBJECTIVES To evaluate the frequency of CD4+CD25+CD127- and CD3+CD8+CD28- regulatory T cells in chronic allograft dysfunction (CAD) and to investigate the expression of TGF-β1 in renal allografts. METHODS Thirty biopsy-proven CAD patients were pair-matched with 30 stable graft function patients and a third group of healthy volunteers. Flowcytometry was performed on PBMCs to determine the frequency of CD3+CD8+CD28- and CD4+CD25+CD127- regulatory T cells in lymphocyt population. TGF-β1 gene expression was assessed by Real Time PCR. RESULTS The percentages of CD3+CD8+CD28- Tregs among renal allograft recipients was higher than healthy controls (p<0.001) since stable graft patients showed the most rates. The frequency of CD4+CD25+CD127- Tregs was lower in CAD patients than stable recipients (p=0.024) and healthy group (p=0.015). TGF-β1 gene expression was greater in CAD patients compared to healthy group (p=0.03) but there was no significant difference between gene expression of stable graft patients and healthy volunteers. CONCLUSION The negative association between the frequency of regulatory T cell subtypes and chronic allograft dysfunction proposes these cells as probable candidates for promoting allograft survival. Moreover, despite the immunoregulatory capacity of TGF-β1, it is likely to be implicated in chronic damages of allograft tissue.

Abstract
BACKGROUND Patients with nephrolithiasis and hyperoxaluria generally are advised to follow a low-oxalate diet. However, most people do not eat isolated nutrients, but meals consisting of a variety of foods with complex combinations of nutrients. A more rational approach to nephrolithiasis prevention would be to base dietary advice on the cumulative effects of foods and different dietary patterns rather than single nutrients. STUDY DESIGN Randomized controlled trial. SETTING & PARTICIPANTS Recurrent stone formers with hyperoxaluria (urine oxalate > 40 mg/d). INTERVENTION The intervention group was asked to follow a calorie-controlled Dietary Approaches to Stop Hypertension (DASH)-style diet (a diet high in fruit, vegetables, whole grains, and low-fat dairy products and low in saturated fat, total fat, cholesterol, refined grains, sweets, and meat), whereas the control group was prescribed a low-oxalate diet. Study length was 8 weeks. OUTCOMES Primary: change in urinary calcium oxalate supersaturation. SECONDARY Changes in 24-hour urinary composition. RESULTS 57 participants were randomly assigned (DASH group, 29; low-oxalate group, 28). 41 participants completed the trial (DASH group, 21; low-oxalate group, 20). As-treated analysis showed a trend for urinary oxalate excretion to increase in the DASH versus the low-oxalate group (point estimate of difference, 9.0mg/d; 95% CI, -1.1 to 19.1mg/d; P=0.08). However, there was a trend for calcium oxalate supersaturation to decrease in the DASH versus the low-oxalate group (point estimate of difference, -1.24; 95% CI, -2.80 to 0.32; P=0.08) in association with an increase in magnesium and citrate excretion and urine pH in the DASH versus low-oxalate group. LIMITATIONS Limited sample size, as-treated analysis, nonsignificant results. CONCLUSIONS The DASH diet might be an effective alternative to the low-oxalate diet in reducing calcium oxalate supersaturation and should be studied more.

Abstract
The BK virus (BKV) is a nonenveloped double-stranded DNA virus of the polyomavirus family that primarily affects immunocompromised people. BKV infects humans at an early age. Initial infections with BKV are mainly asymptomatic and usually remain latent in the brain, peripheral blood, kidneys, and urothelium. Following the primary infection, viruses persist indefinitely as ‘latent’ infections of the kidney and urinary system because the virus is urotheliotropic. Reactivation of the virus infections occurs in individuals with severe immunosuppression states such as kidney and stem cell transplantation and rarely in pregnancy. In this line, BKV has been implicated as a common cause of late-onset haemorrhagic cystitis (HC) in patients who have undergone stem cell transplantation. In contrast, reports of BKV-associated diseases in nontransplant paediatric patients are almost exclusively in patients with human immunodeficiency virus infection. Herein, we report the first case of a child with acute lymphoblastic leukaemia who developed BKV-associated HC without receiving stem cell transplantation while on standard maintenance chemotherapy.

Abstract
BACKGROUND Delayed graft function (DGF), caused by failure of the kidney to function properly after transplantation, has a lower incidence rate in living donor transplantation compared to deceased donor transplantation. The aim of this study was to investigate the possible risk factors related to DGF in living donor transplantations. MATERIAL/METHOD A prospective, observational cohort study of patients undergoing living donor renal transplantation was designed. The incidence of DGF was investigated; the urine levels of neutrophil gelatinase-associated lipocalin (NGAL) and interleukin 18 (IL-18) were measured on the 1st and 3rd day after transplantation, and the relationships of DGF incidence and potential explanatory factors were studied. RESULT DGF was observed in 16.2% of patients. Preliminary univariate analyses showed that older donors, retransplantation, previous blood transfusion, and low urinary output could be eligible predictors for DGF. Analysis of the urinary biomarkers revealed an association between DGF incidence with the level of NGAL on the 1st day after transplantation, level of IL 18 on the 3rd post-operative day, and with the differences in urine NGAL levels measured in 2 samplings. Multivariate logistic regression analysis showed that only the differences between the 1st and 3rd days of urinary NGAL levels could remain in the final model. CONCLUSIONS Although, possibly due to living donor transplantation, none of the patient/donor characteristics could act as an explanatory factor for DGF; however, special attention is still required to target post-operation inflammation and oxidative stress, confirmed by relationship observed between DGF and urine NGAL levels on postoperative days.

Abstract
An Aspergillus fungal ball is a rare cause of ureteral obstruction attributed to indwelling catheters, stents, antibiotics, anastomotic leaks, obstruction, and immunosuppressive therapy and other immunocompromised states. We describe a case of unilateral ureteral obstruction caused by Aspergillus terreus following ureteroscopic lithotripsy and ureteral stenting in a 45-year-old diabetic man. The patient was successfully treated with endoscopic removal of the fungal mass and oral voriconazole. We also review briefly the clinical features, treatment, and outcome in 9 previously reported diabetic patients with ureteral obstruction due to aspergillosis. Obstructive uropathy related to Aspergillus mass may be suspected in diabetic patients with a history of manipulation, impaired kidney function, and persistent passage of a soft mass in urine. Direct microscopy and culture of multiple urine and ureteral washing are necessary for early diagnosis. Antifungal therapy and endoscopic removal of the mass are needed to reduce morbidity.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) with nephrotic syndrome is a rare coincidence. Among 19 reported cases since 1972, focal glomerulosclerosis is the dominant reported pathology. Here, we report the 6th case of focal segmental glomerulosclerosis with ADPKD. A 29-year-old man with a history of APCDK presented with massive proteinuria. He had a history of concurrent leptospirosis and brucellosis, and trace proteinuria and mild hypertension had been diagnosed 4 years earlier. Urine study showed proteinuria (21 g/d) and hematuria. Kidney biopsy report was compatible with focal and segmental sclerosis. The patient received prednisolone and cyclosporine. After 4 months, proteinuria decreased to 600 mg/d. Patients with ADPKD who show massive proteinuria should undergo kidney biopsy. It is possible that different mutations in these patients could clarify the nature of this coincidence.

Abstract
OBJECTIVES The key transcriptional regulator Oct4 is one of the self-renewal and differentiation-related factors in cancer stem cells, where it maintains "stemness" state. Cancer stem cells have been identified in a variety of solid malignancies. They are a small population of tumor cells with stem cell characteristics, which are a likely cause of relapse in cancer patients. Due to high incidence, mortality, and recurrence rates of bladder cancer and the necessity of accurate prediction of malignant behavior of the tumors, we evaluated the prognostic value of Oct4 expression in formalin-fixed paraffin-embedded (FFPE) tissues of bladder cancer. MATERIALS AND METHODS In this study, Oct4 expression was evaluated in 52 (FFPE) tissues of bladder cancer. RNA extraction from samples of 30 patients from the archive of Labbafi-Nejad Medical Centre in Tehran was performed and Oct4 expression levels were examined by semi-quantitative RT-PCR. The intracellular distribution of Oct4 protein was also determined by immunohistochemistry (IHC). RESULTS The results revealed a significant correlation between the expression level of Oct4 and the tumors' grade and stage. A mostly cytoplasmic distribution of Oct4 protein was also confirmed by IHC. CONCLUSION All together, our data indicate that the expression level of Oct4 gene is correlated with the clinical and histopathological prognostic indexes of tumors and thus can be considered as a potential prognostic tumor marker.

Abstract
INTRODUCTION Even though dehydration could aggravate formation of urinary calculi, the effects of fluid and food restriction on calculus formation is not thoroughly defined. The purpose of this study is to evaluate the effects of fluid and food restriction in Ramadan fasting on urinary factors in kidney and urinary calculus formation. MATERIALS AND METHODS Fifty-seven men aged 30 to 55 years old, including 37 recurrent calcium calculus formers and 20 with no history of kidney calculi were evaluated for blood tests, ultrasonography investigations, urinalysis, urine culture, and also 24-hour urine collection test. Metabolites including calcium, oxalate, citrate, uric acid, magnesium, phosphate, potassium, sodium, and creatinine were measured before and during Ramadan fasting. The values of calculus-precipitating solutes as well as inhibitory factors were documented thoroughly. RESULTS Total excretion of calcium, phosphate, and magnesium in 24-hour urine and also urine volume during fasting were significantly lower than those in the nonfasting period. Urine concentration of calcium during fasting was significantly lower than nonfasting (P < .001). Urine concentrations of uric acid, citrate, phosphate, sodium, and potassium during fasting were significantly higher than nonfasting. Uric acid supersaturation was accentuated, and calcium phosphate supersaturation was decreased significantly during fasting. There was no significant increase in calcium oxalate supersaturation during the fasting period. CONCLUSIONS Fasting during Ramadan has different effects on total excretion and concentrations of urinary precipitate and inhibitory factors contributing to calculus formation. We did not find enough evidence in favor of increased risks of calculus formation during Ramadan fasting.

Abstract
Amyloidosis represents a heterogeneous group of disorders of protein metabolism and is characterized by deposition of fibrillar proteins in the intra- and extracellular spaces. Here, a case of generalized amyloidosis associated with neutropenia is presented. She had a medical history of multiple bacterial infections. At the age of 14 years, she developed nephrotic syndrome. An increase of antigenic stimulation during the intermittent bouts of acute infections would have been the main factor responsible for the development of secondary amyloidosis in this case. To the best of our knowledge, coexistence between neutropenic disorders and renal amyloidosis in children has not been reported till date. The purpose of this report is to present a case of secondary amyloidosis associated with neutropenia in pediatric age group, probably for the first time.

Abstract
PURPOSE To evaluate different urinary factors contributing to idiopathic calcium stone disease for determining appropriate medical treatments. MATERIALS AND METHODS Two 24-hour urine samples were collected from 106 male recurrent idiopathic calcium stone formers and another 109 randomly selected men as the control group matching for age. RESULTS Cases had significantly higher mean urine oxalate, calcium, uric acid, and chloride in comparison with the healthy controls (P < .001). After necessary adjustment, only mean urine levels of oxalate and uric acid were higher in stone formers than those in controls. The mean value of supersaturation for calcium oxalate was significantly higher in patients than the controls (P = .001); whereas supersaturation for calcium phosphate and uric acid did not reach statistical significance (P = .675 and P = .675, respectively). Hyperoxaluria and hypercalciuria were among the most frequent abnormalities. After categorizing urine parameter values into four quartiles, the risk of stone formation was found to increase as the urine calcium, oxalate, uric acid, chloride, and citrate rise. In contrast, the risk of stone formation decreased with the increase of urine potassium. CONCLUSION Oxalate seems to play the most important role as urinary stone risk factor in our population followed by calcium and uric acid. In addition to the risk factors, it seems that supersaturation as the sum of all risk factors probably has a high predictive value.

Abstract
PURPOSE To evaluate the predictive factors for prostatic involvement according to the bladder transitional cell carcinoma (TCC) characteristics in a prospective study. MATERIALS AND METHODS Hundred patients with the bladder TCC who had undergone standard radical cystoprostatectomy were enrolled in this study. A number of factors, including vascular and perineural invasion, number of tumors, maximum diameter of the tumor, presence of carcinoma in situ, distance between the tumor and the bladder neck, grade, and local stage of the tumor were recorded, and their relationships with prostatic involvement were studied. In addition, hydronephrosis and age of the patients were included in the analysis. RESULTS The mean age of the patients was 62.6 ± 10.8 years. Of a total of 100 patients, 21 (75%) were found to have prostatic involvement with TCC. Univariate statistical analysis showed that vascular invasion and the distance between the tumor and the bladder neck were significantly related to the prostatic involvement (P = .001 and P < .001) and tumor stage had relatively low P value (P = .08). In the logistic regression, only the distance between the tumor and the bladder neck was found to be significantly related to the prostatic involvement (P = .004). CONCLUSION This study demonstrated that distance between the tumor and the bladder neck is a predictive factor for prostatic involvement; hence, prostate-sparing or capsule-sparing cystectomy in patients with tumors in short distances from prostatovesical junction is not rationale and should be avoided.

Abstract
Human papillomavirus (HPV) infections are associated with benign and malignant lesions of the female and male anogenital tract. Currently the possible role of HPV infections in prostate carcinogenesis is a subject of great controversy. In this study we aimed to investigate the role of HPV infection in prostate carcinoma (PCa). The study included formalin-fixed paraffin-embedded tissue samples of 104 primary prostate adenocarcinoma cases and 104 control tissues of benign prostatic hyperplasia (BPH). HPV-DNA was purified and amplified through MY09/MY11 and GP5(+)/GP6(+) primers and subsequently subjected to sequencing. HPV-DNA was found in 13 of 104 (12.5%) PCa and 8 of 104 (7.7%) BPH samples. High-risk HPVs were detected in 10 of 13 (76.9%) PCa and 5 of 8 (62.5%) BPH samples with positive HPV-DNA. Low-risk HPVs were detected in 3 of 13 (23.1%) PCa and 3 of 8 (37.5%) BPH specimens with positive HPV-DNA. There was no significant difference between PCa and BPH specimens regarding HPV-DNA presence or the detection of high-risk and low-risk types of HPV. Our data do not support the role of HPV infection in prostate carcinoma. Further studies are required to elucidate the role of HPV infection in human prostate carcinogenesis.

Abstract
INTRODUCTION Bone marrow-derived stem cells have a potential capacity to differentiate and accelerate recovery in injured sites of body. Also, factors like granulocyte colony stimulating factor (GCSF) can promote their mobilization to the injured sites. We aimed to investigate the role of GCSF as an alternative therapeutic option instead of mesenchymal stem cells (MSCs) in reperfusion injury. MATERIALS AND METHODS Twenty-nine rats with induced reperfusion injury were divided into 3 groups to receive MSC, GCSF, or nothing (control). Kidney function was assessed by blood urea nitrogen and serum creatinine levels. Histological grading was performed to evaluate the extent of tubular injury and the rate of recovery. RESULTS All the rats reached recovery after 14 days. Rats in the MSC group reached early functional and histological recovery compared to the controls on the 7th day of the study (P = .01 and P = .02, respectively). Compared to the control group, the GCSF group showed a more significant histological recovery on the 7th day (P = .04), but kidney function was ameliorated on the 14th day (P = .04). Both the GCSF and control groups had a significant number of CD34+ cells, which were detected by flow cytometry on the 7th day after reperfusion injury. CONCLUSIONS We found therapeutic effects following administration of both MSC and GCSF which was more evident with MSC in the setting of reperfusion injury. More investigation is required to find optimal time, dose, and route of administration as well as other possible contributing factors.
