Immunosuppressive treatment results in patients with primary IgA nephropathy in Turkiye; the data from TSN-GOLD working group.

Background: Immunoglobulin A (IgA) nephropathy (IgAN) treatment consists of maximal supportive care and, for high-risk individuals, immunosuppressive treatment (IST). There are conflicting results regarding IST. Therefore, we aimed to investigate IST results among IgAN patients in Turkiye.

Characteristics and Survival Results of Peritoneal Dialysis Patients Suffering from COVID-19 in Turkey: A Multicenter National Study.

Introduction: We aimed to study the characteristics of peritoneal dialysis (PD) patients with coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome.

Methods: In this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded.

Post-COVID-19 outcomes of non-dialysis dependent chronic kidney disease patients: a national, multicenter, controlled study.

Purpose: Coronavirus disease 2019 (COVID-19) has a higher mortality in the presence of chronic kidney disease (CKD). However, there has not been much research in the literature concerning the outcomes of CKD patients in the post-COVID-19 period. We aimed to investigate the outcomes of CKD patients not receiving renal replacement therapy.

Trends of primary glomerular disease in Turkey: TSN-GOLD registry report.

Background: Although several renal biopsy registry reports have been published worldwide, there are no data on primary glomerular disease trends in Turkey.

Methods: Three thousand eight-hundred fifty-eight native kidney biopsy records were assessed in the Turkish Society of Nephrology Primary Glomerulopathy Working Group (TSN-GOLD) Registry. Secondary disease and transplant biopsies were not recorded in the registry.

Mortality analysis of COVID-19 infection in chronic kidney disease, haemodialysis and renal transplant patients compared with patients without kidney disease: a nationwide analysis from Turkey.

Background: Chronic kidney disease (CKD) and immunosuppression, such as in renal transplantation (RT), stand as one of the established potential risk factors for severe coronavirus disease 2019 (COVID-19). Case morbidity and mortality rates for any type of infection have always been much higher in CKD, haemodialysis (HD) and RT patients than in the general population. A large study comparing COVID-19 outcome in moderate to advanced CKD (Stages 3-5), HD and RT patients with a control group of patients is still lacking.

Epidemiological features of primary glomerular disease in Turkey: a multicenter study by the Turkish Society of Nephrology Glomerular Diseases Working Group.

Background: The largest data on the epidemiology of primary glomerular diseases (PGDs) are obtained from the databases of countries or centers. Here, we present the extended results of the Primary Glomerular Diseases Study of the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) Working Group.

Methods: Data of patients who underwent renal biopsy and received the diagnosis of PGD were recorded in the database prepared for the study.

Comparison of Widely Used Biochemical Analytes in the Serum and Saliva Samples of Dialysis Patients.

Background: The aim of this study is to determine whether the saliva analysis is an alternative to routine biochemical and immunoassay analyses in patients undergoing perito - neal dialysis (PD) or hemodialysis (HD).

Methods: Study group consisted of 40 healthy control, 44 PD and 44 HD patients. Routine biochemical analytes, thyroid stimulating hormone (TSH), free T3, free T4, vitamin B12, ferritin and folic acid were measured.

Falsely Elevated Glucose Concentrations in Peritoneal Dialysis Patients Using Icodextrin.

Background: Peritoneal dialysis (PD) is used as an alternative to hemodialysis in end-stage renal disease (ESRD). Icodextrin has been used as a hyperosmotic agent in PD. The aim of the study was to assess two different point-of-care testing (POCT) glucose strips, affected and not affected by icodextrin, with serum glucose concentrations of the patients using and not using icodextrin.

MCP-1 and soluble TWEAK levels are independently associated with coronary artery disease severity in patients with chronic kidney disease.

Purpose: Patients diagnosed with chronic kidney disease (CKD) have a greater rate of cardiovascular mortality when compared with the general population. The soluble form of TNF-like weak inducer of apoptosis (TWEAK) and monocyte chemoattractan protein 1 (MCP-1) play important roles in cellular proliferation, migration and apoptosis. The current study aimed to analyze whether soluble TWEAK (sTWEAK) and MCP-1 levels are associated with the severity of coronary arterial disease (CAD) in CKD patients.

The use of mycophenolate mofetil in experimental encapsulating peritoneal sclerosis.

Introduction: Encapsulated peritoneal sclerosis (EPS) is a rare complication of long-term peritoneal dialysis usually associated with the inadequacy and early termination of dialysis modality. Adequate treatment of peritoneal fibrosis has not been achieved by medical intervention so far. Mycophenolate mofetil (MMF), which inhibits inosine monophosphate dehydrogenase reversibly and highly selectively, is the most widely used drug for maintenance immunosupression in renal transplantation.

Is there a relationship between small, dense LDL and lipoprotein--associated phospholipase A2 mass in dialysis patients?

Background: We aimed to measure small, dense LDL (sdLDL) and lipoprotein-associated phospholipase A2 (Lp-PLA2) concentrations and to evaluate their relationship with other risk factors of atherosclerotic heart disease in dialysis patients.

Methods: Study group consisted of 30 peritoneal dialysis and 20 hemodialysis patients with 20 healthy control subjects. sdLDL was measured by homogeneous LDL assay after precipitation of Apo B containing lipoproteins with heparin-magnesium.

Demographic and clinical characteristics of primary glomerular diseases in Turkey.

Background: The aim of our study was to delineate the demographic and clinical properties of primary glomerular diseases of adult population in our country in the light of global knowledge.

Methods: All over the country, a total of 25 centers entered data between May 2009 and July 2012 to the database created by 'Glomerulonephritis Study Group' of Turkish Society of Nephrology. Demographic and clinical characteristics, specific diagnoses of glomerular diseases and biopsy findings recorded to the database were analyzed.

Salt intake is associated with inflammation in chronic heart failure.

Background: Chronic Heart Failure (CHF) is highly prevalent and is associated with high morbidity and mortality rates. It has been well established that excessive intake of sodium chloride (salt) induced hypertension in some populations. Although salt seems to induce cardiovascular diseases through elevation of blood pressure, it has also been indicated that salt can induce cardiovascular diseases independently from blood pressure elevation.

Soluble TWEAK levels are independently associated with coronary artery disease severity in patients with stage 2-3 kidney disease.

Purpose: Patients diagnosed with chronic kidney disease (CKD) have a greater rate of cardiovascular mortality compared with the general population. The soluble form of TNF-like weak inducer of apoptosis (TWEAK) plays a role in cellular proliferation, migration, and apoptosis. The current study aimed to analyze whether soluble TWEAK levels are associated with the severity of coronary arterial disease (CAD) in CKD patients.

Bone morphogenetic protein-7 and disease progression in renal amyloidosis patients.

Introduction: Chronic kidney disease (CKD) is an important health care problem with increasing incidence. Early diagnosis, recognition and interventions to avoid the disease progression have great value. Even some risk factors for disease progression have been described; there are still some dark spots.

The relationship between serum fetuin-A, cystatin-C levels, and microalbuminuria in patients with metabolic syndrome.

Background: The metabolic syndrome, syndrome X, is a group of metabolic disorders in which insulin resistance plays a pivotal role. The MS is an important risk factor for subsequent development of type 2 diabetes and cardiovascular disease. Fetuin-A is a liver derived blood protein that acts as effective inhibitor of soft tissue calcification.

Antibody response after single H1N1 influenza vaccine in chronic dialysis patients.

The first influenza pandemic of this century happened through a rapid spread of a novel swine-derived H1N1 influenza virus. Vaccines are produced in order to avoid the infection. Children and other high risk groups are highly recommended for vaccination due to the high probability of contracting the virus.

Contribution of high flux membranes to the therapy of uremia-associated dyslipidemia.

Cardiovascular diseases are the leading causes of mortality in hemodialysis patients. Uremia induced hypertriglyceridemia; increased levels of lipoprotein remnants and low high-density lipoprotein are the main features of cardiovascular risk factors. Also, elevated oxidative stress and inflammation are the main contributors of endothelial dysfunction.

The efficacy of prophylactic antibiotics administration prior to insertion of tunneled catheter in hemodialysis patients.

Aim And Background: Central venous catheter (CVC)-related blood stream infection is a major cause of morbidity and mortality in patients with end-stage renal diseases. However, CVCs are quite frequently required for vascular access in hemodialysis (HD) patients. Tunneled catheters (TCs) are widely used when a catheter is needed for a long period.
