We reviewed the clinical, histological and serological parameters of microscopic polyangiitis (MPA) associated with antineutrophil cytoplasmic antibodies (ANCA) specific to myeloperoxidase (MPO). Six girls and one boy aged 12.0±2.6 years (7-15 years) met the following inclusion criteria: (1) clinical manifestations of systemic small vessel involvement; (2) histological demonstration of pauci-immune necrotizing glomerulonephritis; and (3) serological findings of increased concentration of MPO-ANCA by ELISA test. The main clinical manifestations were: influenza-like symptoms (100%), hematuria/ proteinuria (100%), purpura (100%), pulmonary-renal syndrome (57%), acute renal failure (ARF) (29%), ischemic cerebral insults (29%), and necrotizing vasculitis of the skin (29%). All patients underwent renal biopsy examined by immunohistochemistry with expression of alpha-smooth muscle actin (alpha SMA) in glomerular and interstitial spaces. Patients were followed from 6 months to 5.5 years (35.4±23.2 months). None of the patients died. Two of seven children who had ARF progressed to end stage renal disease; one developed chronic renal failure, and four normalized renal function. ARF and central nervous system involvement at presentation were parameters of poor renal outcome. A high score of fibro-cellular glomerular crescents was associated with worse prognosis. Early treatment enables a favorable prognosis of MPO-ANCA-associated MPA in children. © IPNA 2005.

Purpose: Indications of kidney cancer outcome in lower-income countries are based on an incidence/mortality ratio due to lack of survival information. This study was conducted to provide outcome data in Serbian patients with renal cell carcinoma (RCC) and to identify prognostic factors that could affect their overall survival (OS). Methods: This retrospective study included 185 patients who underwent nephrectomy. We assessed certain clinicopathological data including age, gender, tumor size, grade, stage and histological subtypes for their possible impact on OS. Results: The 5-year OS was 63.2%. Significant association was found between OS and age (log-rank 12.455, p=0.006), tumor size (log-rank 26.425, p=0.000), grade (log-rank 13.249, p=0.000) and stage (log-rank 43.235, p=0.000). Univariate analysis indicated size (p=0.000), grade (p=0.001) and stage (p=0.000) as prognostic factors for OS. In multivariate analysis, grade (p=0.014) and stage (p=0.000) remained significant predictors of OS. Conclusion: Tumor grade and stage were identified as independent prognostic factors of OS survival in Serbian patients with RCC. © 2017 Zerbinis Publications. All rights reserved.

Aim: To determine whether complexity of chromatin structure in kidney macula densa cells (MDC) decreases during postnatal development in mice. Methods The levels of chromatin structural complexity were measured by determining fractal dimension of MDC nuclei. Kidney tissue was obtained from the total of 32 male Swiss albino mice divided into four age groups (n = 8): newborn (0 days), 10 days old, 20 days old and 30 days old. For a total of 640 MDC chromatin structures, fractal dimension, lacunarity, as well as parameters of Grey level co-occurrence matrix (GLCM) texture were determined. Results: Chromatin fractal dimension in animals aged 10 days, 20 days and 30 days was significantly lower (P < 0.05, P < 0.01 and P < 0.001, respectively), compared with newborn mice. This complexity reduction of chromatin architecture is in accordance with previously published studies, which detected generalized and sustained loss of both tissue and cell complexity during aging. The loss of complexity was texture-independent, since there was no statistically significant difference (P > 0.05) in both chromatin angular second moment and inverse difference moment between the age groups. Conclusion: Our results indicate that age-related nuclear intrinsic factors which do not influence chromatin texture may have an important role in MDC postnatal development. © 2012 The Authors.

Purpose: The purpose of this study was to examine wheth er cytomegalovirus (CMV) is present in different histologi cal types of salivary gland cancer (SGC) by detecting CMV immediate-early (IE) and early gene products, and to deter mine the presence of its association with the overexpression of interleukin (IL)-6. Methods: Immunohistochemical analysis of 92 cases of dif ferent histological types of SGC was performed to determine the presence of IL-6 and CMV antigen and its intensity in tumor tissue. Twenty samples of normal salivary gland tis sue obtained during autopsy served as healthy controls. Results: CMV antigens were not found in healthy acinar tissue of salivary glands, but were expressed in epithelium of salivary gland ducts. Negative expression of CMV an tigens was also found in salivary gland tissue surround ing tumors. On the other hand, CMV was detected in 65/92 SGC cases (70.6%). Higher expression of IL-6 was found in SGC (70.7%) than in normal tissue (20%). There was a high association of CMV antigen presence with the presence of IL-6, and with the IL-6 expression intensity. Conclusions: Positive expression of CMV antigens in a high percentage of SGC cells suggests that it might play an important role in carcinogenesis by increasing IL-6 pro duction and leading to inhibition of apoptosis and tumor development.

Aim. The purpose of this study was to find the incidence of death caused by undiagnosed intracranial tumors. Methods. Autopsy material of the Institute of Forensic Medicine in Belgrade, from 1990 to 2004, was analyzed. The cases in which the cause of death is undiagnosed brain tumor have been extracted. Results. Brain tumors have caused death in 10 cases, of that 7 persons had benign tumors and three malignant and that was 3.9% of 259 indistinct natural deaths caused by pathological disorders of the brain. Of those three cases of malignant neoplasmas of the brain, one has been proven by pathohistological analysis to be an astrocytome of third grade malignity while the second case was a glioblastome. The histological type of tumor in the third case could not be determined because of big necrotic changes in the histological preparation. In the group of benignant tumors leading to death, five cases were menigothel tumors (meningiomas), and two cases were indistinct histogenesis (hemangioglioblastomas). Conclusion. The incidence of sudden death caused by undiagnosed primary intracranial tumors is extremely low. In every case with a susception to intracranial pathology a multidisciplinary approach that includes a total autopsy with thorough documentation and neuropathological tests is necessary. © 2011 Romanian Society of Legal Medicine.

Introduction. Renal biopsy represents a diagnostic method that provides an acurrate diagnosis and adequate treatment of different renal diseases. The first biopsy in our Center was done in June 1982, but it has been performing routinely since 1984. The aim of this study was to report the histopathological features of biopsy proven kidney disease during the past 30 years. Methods. During 30 years, a total of 563 biopsies were performed, of which 530(94%) were succesfull. Data about gender, age, clinical syndrome and histopatological finding were collected from the medical records. Results. The mean age of our patients was 48±11 years, 53% were man (No=272). In the first decade (1982-1994) we performed 118(mean age 50±13), in the second (1995-2004) 208 (mean age 46±14), and in the third decade (2005-2014) 189 renal biopsies (mean age 50±16). Mean number of glomeruli per biopsy was 18±11. There were only two serious complications. The most common clinical syndromes as indication for renal biopsy were: nephrotic proteinuria (41%) followed by asymptomatic urinary abnormalities (AUA-14.8%), chronic renal failure (CRF-13.8%), acute kidney injury (AKI-12.8%), nephritic syndrome (7.6%), systemic lupus erytematosus (SLE-4.5%), isolated haematuria (2.7% of the cases) and other (2.9%). The major histological groups identified were: primary glomerulonephritis (GN) (62.3%), secondary GN (21.2%), and other (16.5% of the cases). The most common primary glomerulonephritis (PGN) were focal segmental glomerulosclerosis-FSGS (19.4%) followed by IgA nephropathy-IgAN (18.8%), membranous GNMGN (16.4%) and mesangial proliferation-MesGN (16%). Interstitial changes were present in 55% of biopsy samples in the first, in 66% in the second and in 63% in the third decade. Blood vessel changes were present in 39% of biopsy samples in the first, in 62% in the second and in 72% in the third decade. Conclusions. The most frequent finding among PGN was mesangioproliferative GN (including IgAN, alltogether 34.8%) followed by FSGS and MGN. Apart from succesful biopsies, there are several aspects to be improved in the future including expanding indications and earlier procedure during the course of chronic kidney disease-CKD.

Purpose: Renal cell carcinoma (RCC) is the most common renal cancer in adults and includes several subtypes that may be distinguished by their histology, genetic background, clinical course and responses to treatment. Human telomerase reverse transcriptase (hTERT), a crucial enzyme for telomere maintenance, has been linked to RCC development. The purpose of this study was to search for genetic and epigenetic alterations in hTERT (promoter mutations and methylation and gene amplification), and to establish a possible association between molecular and clinico-pathological characteristics of RCC. Methods: DNA was extracted from 31 formalin-fixed, paraffin-embedded tumor samples and 23 blood samples from 54 patients with RCC. Polymerase chain reaction (PCR) products were sequenced and analyzed using the Sequencher software. HTERT amplification was determined by quantitative PCR, while the promoter methylation status was assessed by methylation specific PCR. Statistical analysis was performed using SPSS. Results: No mutations could be detected in the hTERT promoter but only a single nucleotide polymorphism (SNP) (-245 T>C). In 54 analyzed RCC cases, the variant allele C was present in homozygous or heterozygous form in 48% of the patients. The C allele was significantly more frequent in low grade tumors (p=0.046). Gene amplification was detected in 19.4% of the 31 RCCs and hTERT methylation in 54.8% of the 31 samples. An association was established between methylation and histological type of RCC (p=0.047). Conclusions: HTERT seems to be implicated in RCC pathogenesis since the promoter polymorphism exerts a modulation effect on tumor behavior. In addition, hTERT promoter methylation status is related to RCC histology. © 2018 Zerbinis Publications. All Rights Reserved.

The aim of our study was to investigate the expression of γ-catenin in normal kidney and in Wilms' tumor by immunohistochemistry and to correlate the results with tumor stage, histological type, and prognostic group. We investigated 28 cases of Wilms' tumor, 2 Wilms' tumor metastases in lungs, and 1 specimen of normal renal tissue. Expression of γ-catenin was detected in 14 cases. There was a weak inverse relationship between γ-catenin expression and tumor stage. Expression of γ-catenin was detected in various histologic types of Wilms' tumor, but there was no statistically significant correlation, except in cases with diffuse anaplasia that were negative. In 2 metastatic cases and in the case of bilateral Wilms' tumor γ-catenin immunostaining was not observed Our findings suggest an absence of strong correlation between the loss of γ-catenin and unfavorable outcome.

Purpose: The purpose of this study was to investigate into the expression of cyclin A and telomerase in renal cell carcinoma (RCC) and to analyze the relationship between expression and the clinicopathological characteristics of the tumor and their impact on survival. Methods: The overall material included 74 samples of RCC and 4 of normal renal tissue. Primary cyclin A antibody from Santa Cruz Biotechnology and TERT MA5-16034 antibody from Thermo Fisher Scientific Inc were used. Staining was performed by streptavidin-biotin technique using DAKO LSAB+ kit. Statistical analyses were performed using of SPSS 23 Statistics software from IBM. Results: No differences in cyclin A and telomerase expression among gender and age groups were found, nor did the tumor dimensions have any significant impact on expression. Also, tumor grades and stages did not differ. However, histological types differed in favor of the papillary type. A significant positive correlation between both markers, as well as between the expression and tumor stage and grade was noticed. Only the tumor stage had negative impact on survival. Conclusions: Although not affecting survival, the expression of cyclin A and telomerase increased with tumor stage and grade, suggesting that cyclin A and telomerase could be potential proliferative immunohistochemical markers of RCC. © 2018 Zerbinis Publications.

Background/Aim. In the past three decades, focal seg-mental glomerulosclerosis (FSGS) was commonly regarded as a part of obesity-related glomerulopathy (ORG), a dis-tinct entity featuring proteinuria, glomerulomegaly, progres-sive glomerulosclerosis, and a decline of renal function. The present study aimed to evaluate the glomerular morphome-try, clinical features, and a two-year outcome in the obese and non-obese FSGS patients. Methods. The study includ-ed 35 FSGS patients (23 males, aged 46.5 ± 15.2 years) di-vided into two groups: Obese [body mass index (BMI) ≥ 27 kg/m2 (18 patients, aged 47.2 ± 15.5 years)] and non-obese [BMI < 27 kg/m2 (17 patients, aged 45.7 ± 15.2 years)]. The serum concentrations of proteins, albumin, cholesterol, tri-glyceride, and creatinine were determined at the time of the biopsy, and 6, 12, and 24 months after the biopsy. Cock-croft-Gault (BMI < 27 kg/m2) and Cockcroft-GaultLBW (BMI ≥ 27 kg/m2) formulas were calculated. Glomerular radius (GR), glomerular volume (GV), and glomerular den-sity (GD) were compared morphometrically between the two groups. Results. At the time of the kidney biopsy and 6 months later, the obese had significantly lower glomerular filtration rate (GFR) compared to the non-obese. After 24 months of follow-up, there were not any differences be-tween the groups. The obese had a significantly higher GR (109.44 ± 6.03 μm vs. 98.53 ± 14.38 μm) and GV (3.13 ± 0.49 × 106 μm3 vs. 2.26 ± 0.83 × 106 μm3), and only slightly lower GD (1.91 ± 0.39/mm2 vs. 1.95 ± 0.61/mm2) compared to the non-obese. A significant positive associa-tion between GV and BMI (r = 0.439) was found. After 12 months of follow-up, a significantly higher percentage of the non-obese patients reached complete remission com-pared to the obese (71.4% vs. 37.5%, respectively; p = 0.041), but after 24 months there were no significant differences. Conclusion. Obese patients, at the time of the kidney biopsy and 6 months later, had already a significantly lower kidney function compared to the non-obese ones. However, 12 and 24 months after, this difference was not statistically significant. Also, 24 months after, there was no significant difference between the two groups in the per-centage of patients with complete remission of the nephrot-ic syndrome. © 2021 Inst. Sci. inf., Univ.

Introduction: In patients with diabetes mellitus (DM), non-diabetic renal disease (NDRD) can also occurs, as well as diabetic nephropathy. NDRD is most accurately diagnosed using kidney biopsy. Aim: The aim of the study was to investigate the incidence and type of NDRD diagnosed by kidney biopsy in patients with type 2 DM and the correlation of clinical and laboratory findings with histopathological diagnosis. Material and Methods: From April 2007 to October 2018, 290 kidney biopsies were performed at the Department of Nephrology, Internal Medicine Clinic in Banja Luka, out of which 18 patients (males 9, mean age 59.8 years) were with type 2 DM. The US-guided (ultrasound device: Toshiba Famio 5) kidney biopsy was performed using an automatic biopsy instrument FAST-GUN® with needle 16G. Kidney tissue samples were analyzed by light microscopy and immunofluorescence. Results: In 18 patients with type 2 DM, the average duration of the disease was 5.9 years, 5 patients had a retinopathy, and 16 patients had hypertension. Biopsy indications were: nephrotic syndrome in 11 patients, asymptomatic urinary abnormalities in 3 patients, and rapid chronic renal failure progression. Unsatisfactory quality sample for pathohistological analysis was obtained in one patient, and out of the other 17, 6 (35.3%) had NDRD, 3 (17.6%) had NDRD superimposed with the diabetic nephropathy, and 8 (47.1%) had diabetic nephropathy. Of the patients who had NDRD, 3 had membranous glomerulonephritis, 1 had focal segmental glomerulosclerosis, and two had hypertensive nephroangiosclerosis. Out of patients with coexisting NDRD and diabetic nephropathy, 2 had hypertensive nephroangiosclerosis and one diabetic nephropathy and lupus nephritis. Conclusion: NDRD was diagnosed using kidney biopsy in 9/17 patients with type 2 DM, which confirms the significance of the kidney biopsy in patients with DM with properly indications. Accurate diagnosis provides disease specific treatment and thus significantly improves the long-term prognosis of the patient.

Purpose: Survivin is thought to play an important role in carcinogenesis and is found to be associated with poor clinical outcome in various malignancies. Gene -31 G/C polymorphism has been identified as a risk factor for the development of several types of tumors. The purpose of this study was to investigate the association between survivin gene promoter -31C/G polymorphism and urothelial carcinoma (UC) risk in Serbian population and to compare the different expressions of survivin in UC of different disease stages, histological grades and tumor location in the upper or lower urinary tract. Methods: DNA from 94 patients with primary UC and from 82 healthy subjects was subjected to PCR restriction fragment length polymorphism analysis (PCR-RFLP) to identify individual genotypes. UC samples were subjected to immunohistochemical analysis to assess survivin expression in these lesions. Results: It was observed that the frequency of G/G genotype was greater in patients with UC (58.7%) than in controls (32%). Compared with study subjects carrying the C/G or C/C genotypes, significantly increased UC risk was found for individuals carrying the GIG genotype. Those carrying the G/G genotype had a significantly increased UC risk compared with those with C/G or C/C genotypes. Patients with UC carrying the G/G genotype had a greater prevalence of muscle-invading (stage T2-T4), high-grade (G2) tumor and immunohistochemicaly overexpressed survivin compared with those carrying the C/G or C/C genotypes. Conclusions: G/G genotype of the -31C/G polymorphism might be a risk factor for UC development.

Background. There is not enough epidemiologic data of biopsy proven renal diseases. This is the first report of clinicopathologic correlations over a period of 20 years from central Balkan country-Serbia. Methods. A retrospective review of reports of 2 362 native renal biopsies performed on patients at the leading nephrology unit in Serbia from 1987 to 2006 was undertaken. Patients were divided in two groups according to age: younger (<60 years old) and older (≥60 years old). Results. The annual incidence of renal biopsies increased from 3.9 p.m.p./year in 1987 to 12.5 p.m.p/year in 2006. The most common clinical syndrome as an indication for renal biopsy was nephrotic syndrome (NS) (53.6%). Membranous nephropathy was the most frequent cause of NS (21.6%). Primary glomerulonephritis (PGN) accounted for about two thirds of all performed biopsies. Non-IgA mesangioproliferative GN was the most frequent primary GN accounting for almost 25% of all PGN in our whole population, while the prevalence of IgA nephropathy was only 12%. Lupus nephritis was the most frequent secondary glomerulonephritis (75.6%). Conclusions. This report represents epidemiological overview on biopsy proven renal disease coming from one specific Balkan country, which was under economic sanctions for almost half the studied period. We are hoping that this register will be the basis for developing not only a national register but also a register that will encompass all Balkan countries. © The Author [2008].

Survivin, an apoptotic inhibitor, is overexpressed in various types of cancer. Mechanisms of survivin upregulation are still poorly understood, but single nucleotide polymorphisms in the survivin gene promoter have been shown to modulate survivin expression and consequently the risk for some types of cancer. The aim of the present study was to investigate whether survivin promoter -31 G/C and -241 C/T polymorphisms could represent susceptibility factors for Wilms tumor (WT) development in Serbian population. Genotype and allele frequencies for the 2 polymorphisms in survivin promoter have been analyzed by polymerase chain reaction/restriction fragment length polymorphism in 59 WT patients and 82 controls. The frequencies of alleles and genotypes were significantly different between patients and controls for the -31 G/C polymorphism. Individuals with CC and CG genotypes had significantly decreased risk of WT compared with GG individuals (odds ratio 0.26, 95% confidence interval, 0.07-0.96; odds ratio 0.30, 95% confidence interval, 0.15-0.60). There was also a statistically significant difference in genotype frequencies between intermediate and high-risk prognostic groups (P=0.015). The -241 C/T polymorphism did not show association with WT susceptibility. Our findings suggest that the G allele at -31 survivin gene promoter position is associated with a significantly higher cancer risk in Serbian children, with a gene dosage effect.
