Biopsy-proven BK virus nephropathy in renal transplant recipients: A multi-central study from Turkey (BK-TURK STUDY).

Aim: BK polyomavirus infection is a challenging complication of renal transplantation. The management is not standardized and is based on reports from transplantation centers' experiences, usually with small sample sizes. Therefore, we aimed to present our countrywide experience with BK virus nephropathy (BKVN) in renal transplant recipients.

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.

Psychological review of hemodialysis patients and kidney transplant recipients during the COVID-19 pandemic.

Background: Kidney transplantation (KT) and end-stage renal disease (ESRD) requiring hemodialysis (HD) increase the incidence of morbidity and mortality associated with coronavirus disease 2019 (COVID-19) infection. The COVID-19 pandemic has had a negative effect on the psychological well-being of COVID-19 patients, especially those with a high-risk of infectious complications. The prevalence of anxiety and depression is known to be higher in ESRD patients undergoing HD than in the general population.

De Novo Malignancies After Kidney Transplant: Where Do We Stand and Does the Head and Neck Region Require More Caution?

Objectives: The aim of this study was to investigate the characteristics of de novo malignancies arising in kidney transplant recipients followed in a tertiary hospital in Turkey and to examine the tumors in the head and neck region as a subgroup.

Materials And Methods: Data from kidney transplant recipients treated at our institution between January 2010 and July 2022 were retrospectively analyzed in this single-center study. Data regarding malignancies were noted according to the pathologists' reports.

Comparison of geriatric nutritional risk index and creatinine index in short-term mortality prediction in maintenance hemodialysis patients.

Background: The aim of this study is to analyze and compare the predictive values of the Geriatric Nutritional Risk Index (GNRI) and Creatinine Index (CI) in the short-term mortality of maintenance hemodialysis patients and to determine their best cut-offs.

Methods: A total of 169 adult hemodialysis patients were included in this retrospective, cross-sectional, and single-center study. The demographic, clinical, and laboratory data of the month in which the patients were included in the study were obtained from their medical files and computer records.

Vitamin D deficiency may predispose patients to increased risk of kidney transplant rejection.

Background: Vitamin D deficiency occurs in more than 80% of kidney transplant recipients. Its immunomodulatory effects can predispose transplant recipients to rejection and chronic allograft nephropathy (CAN). This study determined the association between serum 25 (OH) vitamin D, biopsy-proven allograft rejection, and CAN rates.

The relationship between depression, anxiety, quality of life levels, and the chronic kidney disease stage in the autosomal dominant polycystic kidney disease.

Purpose: Decreased quality of life, anxiety, depression, and other negative psychosocial factors in autosomal dominant polycystic kidney disease (ADPKD) may lead to the patient's attitudes that reduce treatment effectiveness. We aimed to evaluate the relationship between the depression, anxiety, perceived social support, genetic psychosocial risk and quality of life levels, and chronic kidney disease (CKD) stage in ADPKD and to investigate the relationship between these variables/parameters and the dietary compliance that is an essential factor in the course of the disease.

Methods: 100 ADPKD patients were enrolled in this cross-sectional study.

A rare case of acute acalculous cholecystitis secondary to hantavirus infection with renal syndrome.

Hantaviruses are single-stranded RNA viruses. They are transmitted to humans by rodents and insectivore hosts. Some Hantavirus subtypes are the causative agents of haemorrhagic fever with renal syndrome (HFRS), which is characterized by fever, thrombocytopenia, and acute kidney injury.

The Longitudinal Evolution of Post-COVID-19 Outcomes Among Hemodialysis Patients in Turkey.

Introduction: Hemodialysis (HD) patients have increased risk for short-term adverse outcomes of COVID-19. However, complications and survival at the post-COVID-19 period have not been published extensively.

Methods: We conducted a national, multicenter observational study that included adult maintenance HD patients recovered from confirmed COVID-19.

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.

Pregnancy and its outcomes in hemodialysis patients in Turkey.

Background/aim: This study aimed to investigate pregnancy frequency and evaluate the factors affecting live births in hemodialysis (HD) patients.

Materials And Methods: Female HD patients whose pregnancy was retrospectively reported between January 1, 2014, and December 31, 2019. The duration of HD, primary disease, whether the pregnancy resulted in abortion, stillbirth, or live birth, whether the HD duration was prolonged after diagnosing the pregnancy and whether it accompanied preeclampsia were recorded.

COVID-19 infection in a kidney transplant recipient-special emphasis on pharmacokinetic interactions: A case report.

Background: Solid organ transplant recipients are considered to be at high-risk of developing coronavirus disease 2019 (COVID-19)-related complications. The optimal treatment for this patient group is unknown. Consequently, the treatment of COVID-19 in kidney transplant recipients should be determined individually, considering patient age and comorbidities, as well as graft function, time of transplant, and immunosuppressive treatment.

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.

The impact of arteriovenous fistulas and tunneled cuffed venous catheters on morbidity and mortality in hemodialysis patients: A single center experience.

Background/aim: Hemodialysis is the most used renal replacement therapy option for patients with end-stage renal disease. Arteriovenous fistulas (AVFs) and tunnel-cuffed venous catheters (tCVC) are commonly used vascular access routes and have advantages and disadvantages compared to each other. This study focuses on the effects of AVFs and tCVCs on morbidity and mortality in hemodialysis patients.

Secukinumab may be remedy for systemic amyloidosis findings secondary to hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory disease of follicular epithelium; many comorbidities occur that disrupt the quality of life of patients. Amyloidosis is one of them. We present a case with systemic amyloidosis secondary to HS and responding positively to secukinumab therapy.

Is dialysis adequacy a useful predictor for sexual function in males and females with end-stage renal disease?

Introduction: The development of sexual dysfunction (SD) in dialysis patients is multifactorial. We aimed to evaluate whether adequate dialysis had an effect on the development of SD in male and female patients undergoing dialysis due to end stage renal disease. Anxiety, depression, health-related quality of life and the other risk factors related to dialysis were also evaluated in terms of SD.

Listening to music during arteriovenous fistula surgery alleviates anxiety: A randomized single-blind clinical trial.

Background: Both end-stage renal disease and being wait-listed for a kidney transplant are anxiety-causing situations. Wait-listed patients usually require arteriovenous fistula surgery for dialysis access. This procedure is performed under local anesthesia.

Successful Treatment of Posttransplant Recurrent Complement C3 Glomerulopathy with Eculizumab.

Two-thirds of complement C3 glomerulopathy (C3G) recur after transplantation and commonly cause graft loss. There is not a standard treatment protocol for these cases. We present a kidney transplant patient with recurrent C3G who was successfully treated with eculizumab.

The association between serum hepcidin-25 level and subclinical atherosclerosis in peritoneal dialysis patients.

Objective: Recently, the role of hepcidin as a cardiovascular marker in the chronic kidney disease (CKD) population has gained interest. The aim of this study was to investigate the relationship between serum hepcidin-25, inflammation, iron parameters, and carotid intima-media thickness (CIMT) in peritoneal dialysis (PD) patients.

Methods: A total of 58 patients (30 male, 51.
