Pretransplant Parathyroidectomy in Patients with Severe Secondary Hyperparathyroidism and Long-Term Effectiveness After Kidney Transplantation.

Kidney transplantation (KT) is the best option for patients with end-stage renal disease, but recipients still have legacy bone mineral disease from the pretransplant period, especially patients with severe secondary hyperparathyroidism (sHPT). Patients who had severe sHPT and underwent KT were analyzed retrospectively. Two groups were identified (patients with severe sHPT who had parathyroidectomy or calcimimetic before KT).

Could mesangial C3 deposition be an independent prognostic marker in immunoglobulin A nephropathy?

Background: Immunoglobulin A nephropathy (IgAN) is a common primary glomerulonephropathy. There is evidence that mesangial C3 deposition plays a role in the development of the disease. The aim of this study was to examine the effect of C3 deposition on the prognosis of IgAN patients.

Impact of HLA polymorphisms on the susceptibility to SARS-CoV-2 infection and related mortality in patients with renal replacement therapy.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection could present in a clinical spectrum of varying severity. Human leukocyte antigen (HLA) is a crucial component of the viral antigen presentation pathway and immune response to the virus. Therefore, we aimed to assess the impact of HLA allele polymorphisms on the susceptibility to SARS-CoV-2 infection and related mortality in Turkish kidney transplant recipients and wait listed patients, along with clinical characteristics of the patients.

Comparison of soluble suppression of tumorigenicity 2 and brachial hemodynamic parameters between dialysis modalities in patients with end-stage kidney disease.

Purpose: Major cardiovascular events (MACE) are the leading cause of mortality in patients with chronic kidney disease. Although hemodialysis (HD) and peritoneal dialysis (PD) are comparable in survival, patients with HD have a significantly higher risk of developing MACE. Soluble suppression of tumorigenicity 2 (sST2) is a cardiac biomarker, that does not vary with age, gender, and kidney function.

Outcomes of early-start peritoneal dialysis (PD) and the comparison with urgent-start hemodialysis and conventional-start PD.

Background: Limited data in the literature is comparing early-start peritoneal dialysis (PD), urgent-start hemodialysis (HD) with the jugular central venous catheter (CVC), and conventional-start PD.

Methods: This retrospective study was conducted with 148 patients with early-start PD, 104 patients with conventional-start PD, and 100 patients with urgent-start HD. Early-start PD was defined as catheter break-in time between 3 and 14 days.

Association of longitudinal high-sensitive C-reactive protein levels with changing membrane characteristics in peritoneal dialysis.

Background: Increasing peritoneal permeability with ultrafiltration and solute removal inadequacy is a challenging issue in peritoneal dialysis (PD). Decreasing permeability is less frequent but also results in diminished solute clearance. We evaluated the association between longitudinal high-sensitive C-reactive protein (hs-CRP) values and the change in transport characteristics of the peritoneal membrane in PD patients.

Predictive value of neutrophil-to-lymphocyte ratio in terms of need for intensive care unit and mortality in maintenance hemodialysis patients with COVID-19.

Introduction: The transmission risk of Severe Acute Respiratory Syndrome Coronavirus-2 virus infection is increased in maintenance hemodialysis (MHD) patients, and also the disease causes much higher mortality than the normal population. The aim of this study is to define the predictive value of neutrophil-to-lymphocyte ratio (NLR) in terms of worse outcomes in MHD patients.

Methods: A total of 123 MHD patients who had received inpatient care due to COVID-19 infection were included in this multicentered retrospective study.

The relationship between glomerular IgG staining and poor prognostic findings in patients with IgA nephropathy: the data from TSN-GOLD working group.

Background: Galactose-deficient IgA1 (Gd-IgA1) has an increased tendency to form immunocomplexes with IgG in the serum, contributing to IgAN pathogenesis by accumulating in the glomerular mesangium. Several studies showed that glomerular IgG deposition in IgAN is an important cause of mesangial proliferation and glomerular damage. This study aims to determine the association of the positivity of IgG and the intensity of IgG staining with a poor renal prognosis.

Could urinary kidney injury molecule-1 be a good marker in subclinical acute kidney injury in mild to moderate COVID-19 infection?

Purpose: To evaluate urinary kidney injury molecule-1 (uKIM-1), which is a proximal tubule injury biomarker in subclinical acute kidney injury (AKI) that may occur in COVID-19 infection.

Methods: The study included proteinuric (n = 30) and non-proteinuric (n = 30) patients diagnosed with mild/moderate COVID-19 infection between March and September 2020 and healthy individuals as a control group (n = 20). The uKIM-1, serum creatinine, cystatin C, spot urine protein, creatinine, and albumin levels of the patients were evaluated again after an average of 21 days.

Obstetric and long-term graft outcomes in pregnant kidney transplant recipients: A single-center experience.

Background: Kidney transplantation (KT) is the best option for many women with end-stage renal disease desiring pregnancy. The aim of this study was to investigate obstetric and graft outcomes among KT recipient women in our center.

Methods: Maternal and fetal data were assessed in 29 pregnancies of 18 female KT recipients.

Characteristics of primary glomerular diseases patients with hematuria in Turkey: the data from TSN-GOLD Working Group.

Purpose: Hematuria is one of the most common laboratory findings in nephrology practice. To date, there is no enough data regarding the clinical and histopathologic characteristics of primary glomerular disease (PGD) patients with hematuria in our country.

Methods: Data were obtained from national multicenter (47 centers) data entered into the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) database between May 2009 and June 2019.

Combining clinical features and MEST-C score in IgA nephropathy may be a better determinant of kidney survival.

IgA nephropathy (IgAN) is a heterogeneous disease with highly variable clinical and histopathological features. We investigated the effects of Oxford classification and clinical features on renal survival in patients with IgAN. This retrospective observational study conducted from 2013 to 2017.

Effects of medium cut-off dialysis membranes on inflammation and oxidative stress in patients on maintenance hemodialysis.

Purpose: Medium cut-off membranes were developed for providing increased clearance of larger middle-molecule uremic toxins. We compared the effect of low-flux, medium cut-off, and high-flux membranes on chronic inflammation and oxidative stress in patients with maintenance hemodialysis.

Methods: A total of 42 patients were enrolled in this study.

Real-life outcomes of unselected acute promyelocytic leukemia patients: a single-center 14-year experience.

Background: After the inclusion of all-trans retinoic acid (ATRA) into the treatment of Acute Promyelocytic leukemia (APL), a notable improvement concerning the survival rates of patients with APL has been observed. However, the population-based studies demonstrated that there was no marked improvement in the survival of patients after the 2000s. We aim to describe the clinical response and prognosis of adult patients diagnosed with APL and examine the change in these outcomes by the time period of diagnosis.

Automated Remote Monitoring for Peritoneal Dialysis and Its Impact on Blood Pressure.

Introduction: Peritoneal dialysis (PD) provides a safe, home-based continuous renal replacement therapy for patients. The adherence of the patients to the prescribed dialysis fluids cannot always be monitored by physicians. Remote monitoring automated peritoneal dialysis (RM-APD) can affect patients' compliance with treatment and, thus, clinical outcomes.
