Successful Endovascular Treatment of Postbiopsy AVF in Transplanted Kidneys: Lessons Learned from Two Cases in Multiorgan Transplant Recipients.

Allograft biopsy is a cornerstone in the management of transplanted kidneys. It is a safe procedure, often performed in the outpatient setting. A rare complication is formation of a postbiopsy arteriovenous fistula (AVF).

Specific antigen-based stratification of membranous nephropathy in patients after haematopoietic stem cell allotransplantation - a case series and literature review.

Background: Nephrotic syndrome (NS) is a rare complication that can occur after haematopoietic stem cell transplantation (HSCT). In patients with membranous nephropathy (MN) who have undergone allogeneic HSCT, a new antigen called protocadherin FAT1 has been identified. Our objective is to present a case series of MN patients after HSCT with a novel antigen-based stratification.

Chronic Kidney Disease in Balkan Countries-A Call to Action for Timely Diagnosis and Monitoring.

Chronic kidney disease (CKD) is a serious illness with important consequences for patients and health systems. Estimation of prevalence and incidence, especially in early stages, is difficult due to a lack of epidemiological studies and consolidated registries. In general, the disease awareness is low, and thus CKD is not timely diagnosed in most cases.

Stage II of Chronic Kidney Disease-A Tipping Point in Disease Progression?

Chronic kidney disease (CKD) is the progressive loss of renal function. Although advances have been made in understanding the progression of CKD, key molecular events in complex pathophysiological mechanisms that mark each stage of renal failure remain largely unknown. Changes in plasma protein profiles in different disease stages are important for identification of early diagnostic markers and potential therapeutic targets.

First Characterization of ADAMTS-4 in Kidney Tissue and Plasma of Patients with Chronic Kidney Disease-A Potential Novel Diagnostic Indicator.

Background: We have previously shown that metzincin protease ADAMTS-4 accompanies renal fibrogenesis, as it appears in the blood of hemodialysis patients. Methods: Native kidney (NKB) and kidney transplant (TXCI) biopsy samples as well as plasma from patients with various stages of CKD were compared to controls. In paired analysis, 15 TXCI samples were compared with their zero-time biopsies (TX0).

Drug-drug-gene interactions as mediators of adverse drug reactions to diclofenac and statins: a case report and literature review.

Concomitant treatment with drugs that inhibit drug metabolising enzymes and/or transporters, such as commonly prescribed statins and nonsteroidal anti-inflammatory drugs (NSAIDs), has been associated with prolonged drug exposure and increased risk of adverse drug reactions (ADRs) due to drug-drug interactions. The risk is further increased in patients with chronic diseases/comorbidities who are more susceptible because of their genetic setup or external factors. In that light, we present a case of a 46-year-old woman who had been experiencing acute renal and hepatic injury and myalgia over two years of concomitant treatment with diclofenac, atorvastatin, simvastatin/fenofibrate, and several other drugs, including pantoprazole and furosemide.

Corrigendum to "The Association of TNF-Alpha Inhibitors and Development of IgA Nephropathy in Patients with Rheumatoid Arthritis and Diabetes".

[This corrects the article DOI: 10.1155/2020/9480860.].

The Association of TNF-Alpha Inhibitors and Development of IgA Nephropathy in Patients with Rheumatoid Arthritis and Diabetes.

IgA nephropathy (IgAN) is a rather uncommon complication of TNF-alpha inhibition with a range of findings such as asymptomatic microscopic/macroscopic hematuria or different degrees of proteinuria and could progress to end-stage renal disease. We are reporting three patients with longstanding rheumatoid arthritis (RA), which developed IgAN while receiving TNF-alpha inhibitors. All off our three patients had RA, which lasted 2-4 years, and none of them had a prior history of chronic kidney disease.

Validation of distinct pathogenic patterns in a cohort of membranoproliferative glomerulonephritis patients by cluster analysis.

Background: A novel data-driven cluster analysis identified distinct pathogenic patterns in C3-glomerulopathies and immune complex-mediated membranoproliferative glomerulonephritis. Our aim was to replicate these observations in an independent cohort and elucidate disease pathophysiology with detailed analysis of functional complement markers.

Methods: A total of 92 patients with clinical, histological, complement and genetic data were involved in the study, and hierarchical cluster analysis was done by Ward method, where four clusters were generated.

C4 nephritic factor in patients with immune-complex-mediated membranoproliferative glomerulonephritis and C3-glomerulopathy.

Background: Acquired or genetic abnormalities of the complement alternative pathway are the primary cause of C3glomerulopathy(C3G) but may occur in immune-complex-mediated membranoproliferative glomerulonephritis (IC-MPGN) as well. Less is known about the presence and role of C4nephritic factor(C4NeF) which may stabilize the classical pathway C3-convertase. Our aim was to examine the presence of C4NeF and its connection with clinical features and with other pathogenic factors.

Treatment of Hypertension Induced Albuminuria.

Regardless of having a similar antihypertensive effect, different antihypertensive drug classes have a different effect on albuminuria. Patients with albuminuria will usually need more than one drug to achieve blood pressure control, particularly if the aim is also to reduce albuminuria. Albuminuria is independently associated with cardiovascular and renal risk regardless of diabetes status.

Acute Kidney Failure as a Single Complication of Varicella Virus Infection in an Adult Patient.

Background: Varicella zoster virus (VZV) is distributed worldwide and is highly contagious. In adults and immunosuppressed patients of any age, the clinical course is much more severe. The most severe complications are pneumonia (the main cause of lethal outcomes in this infection), encephalitis, and very rarely Reye syndrome and hepatitis.

Mechanisms of fetal epigenetics that determine telomere dynamics and health span in adulthood.

Advances in epigenetics now enable us to better understand environmental influences on the genetic background of human diseases. This refers especially to fetal development where an adverse intrauterine environment impacts oxygen and nutrient supply to the fetus. Recently, differences in telomere length and telomere loss dynamics among individuals born with intrauterine growth restriction compared to normal controls have been described.

Chronic dietary exposure to aristolochic acid and kidney function in native farmers from a Croatian endemic area and Bosnian immigrants.

Background And Objectives: Improvements in agricultural practices in Croatia have reduced exposure to consumption of aristolochic acid-contaminated flour and development of endemic (Balkan) nephropathy. Therefore, it was hypothesized that Bosnian immigrants who settled in an endemic area in Croatia 15-30 years ago would be at lower risk of developing endemic nephropathy because of reduced exposure to aristolochic acid. To test this hypothesis, past and present exposure to aristolochic acid, proximal tubule damage as a hallmark of endemic nephropathy, and prevalence of CKD in Bosnian immigrants were analyzed.

Adiponectin is not associated with blood pressure in normotensives and untreated hypertensives with normal kidney function.

The role of adiponectin in hypertension is still a matter of debate. Obtained conflicting results could be mostly explained with diversity of subjects included in different studies. Our aim was to analyze association of adiponectin with blood pressure (BP) in a group of normotensive and untreated hypertensive subjects.

[Treatment of resistant primary glomerulopathies].

Considerable progress in understanding of the pathogenesis of a number of primary glomerular diseases is evident. Scientific achievements in this field led to reclassification of certain types of glomerulonephritides, development of new diagnostic tests, as well as new therapeutic approaches. These new findings will enable us to treat primary glomerulopathies more efficiently thus reducing incidence of resistant disease.

[Classification of glomerulopathies].

Glomerular diseases may be classified as acute or chronic, primary or secondary, hereditary or acquired, proliferative or non-proliferative etc. The most commonly used is the classification according to the histopathological finding. For certain types of glomerulonephritides histopathological image, as well as clinical presentation, may vary widely.

Arterial stiffness in atherosclerotic renovascular hypertension.

Objective: Arterial stiffness is an independent cardiovascular risk factor. Aging, high blood pressure and increased renin-angiotensin system activity contribute to increased arterial stiffness in patients with atherosclerotic renovascular hypertension (aRVH). A literature search failed to identify any study related to this topic.

The assessment of arterial stiffness in endemic (Balkan) nephropathy patients undergoing haemodialysis.

Cardiovascular (CV) complications are the most important cause of morbidity and mortality in patients with advanced chronic kidney disease (CKD). Arterial stiffness (AS) has been recognized as a strong and independent predictor for CV events in CKD. Our aim was to assess indices of AS in a group of Endemic (Balkan) Nephropathy (EN) patients undergoing haemodialysis (HD).

[Blood pressure measurement--do not sweat the small stuff and it is all small stuff?! Position paper of the Croatian national referral center for hypertension, center of excellence of the European Society of Hypertension].

Office blood pressure measurement using mercury sphygmomanometer is the gold standard for making diagnoses of hypertension, evaluation of cardiovascular risk and estimation of obtained control of treated hypertensives. The vast majority of epidemiologic data are based on this method. However, the importance of blood pressure variability, white coat effect as well as availability of simple devices, home and ambulatory blood pressure measurements became routine parts in routine clinical work.

Hypertension, overweight and obesity in adolescents: the CRO-KOP study.

The objective of this study was to determine the prevalence of hypertension, overweight and obesity in Croatian adolescents. In this cross-sectional survey (the sub-study of the EH-UH study) 375 boys and 381 girls (mean age 15.9 +/- 0.
