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.

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.

Description and Outcomes of Three Different End-to-Side Microsurgical Techniques for the Anastomosis of Accessory Renal Artery With the Dominant Renal Artery in Kidney Transplantation.

Background: In this study, we compared the outcomes of three different surgical microscope-assisted end-to-side anastomosis techniques between the dominant and accessory renal arteries during living donor kidney transplant.

Methods: The demographics, serum creatinine levels, warm and cold ischemia times, rate of complications, and incidence of delayed graft function of 135 kidney recipients were analyzed according to the type of arterial anastomosis. Group A (n = 98) had one dominant renal artery (DRA) with one end-to-side anastomosis to the external iliac artery (EIA) using a surgical microscope.

Immunological Results of Long-Term Use of Mammalian Target of Rapamycin (mTOR) Inhibitors and Its Effects on Renal Graft Functions.

BACKGROUND Calcineurin inhibitor drugs (CNI), which are the basis of immunosuppression in kidney transplantation, contribute to renal graft loss, with increased morbidity and mortality due to their potentially harmful effects on the renal graft, cardiovascular system, and tumor pathology. For this reason, the mammalian target of rapamycin inhibitors (mTORi) such as sirolimus (SRL) and everolimus (EVE) has been preferred more frequently, as they are associated with fewer complications and longer graft function. MATERIAL AND METHODS We enrolled 89 adult renal transplant patients (37 patients on mTORi and 52 on CNI) who had similar age, sex, primary renal disease, dialysis type, post-transplant follow-up period, and donor type.

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.

Relationship Between Angiotensin-converting Enzyme Gene Polymorphism and QT Dispersion in Hemodialysis Patients.

Introduction: The angiotensin-converting enzyme (ACE) gene insertion or deletion in long-term hemodialysis patients may be associated with corrected QT interval prolongation, leading to fatal arrhythmias. The ACE D allele is known to increase the risk of malignant ventricular arrhythmias and is also associated with increased QT dispersion after myocardial infarction and hypertension. This study aimed to evaluate the relationship between ACE gene polymorphism and QT dispersion in hemodialysis patients.

Screening Fabry's disease in chronic kidney disease patients not on dialysis: a multicenter study.

Objectives: Fabry's disease is an X-linked inherited, rare, progressive, lysosomal storage disorder, affecting multiple organs due to the deficient activity of α-galactosidase A (α-Gal A) enzyme. The prevalence has been reported to be 0.15-1% in hemodialysis patients; however, the information on the prevalence in chronic kidney disease not on dialysis is lacking.

The DESCARTES-Nantes survey of kidney transplant recipients displaying clinical operational tolerance identifies 35 new tolerant patients and 34 almost tolerant patients.

Background: Kidney recipients maintaining a prolonged allograft survival in the absence of immunosuppressive drugs and without evidence of rejection are supposed to be exceptional. The ERA-EDTA-DESCARTES working group together with Nantes University launched a European-wide survey to identify new patients, describe them and estimate their frequency for the first time.

Methods: Seventeen coordinators distributed a questionnaire in 256 transplant centres and 28 countries in order to report as many 'operationally tolerant' patients (TOL; defined as having a serum creatinine <1.

Allergic rhinitis and its relationship with autoimmune thyroid diseases.

Background: Autoimmune thyroid diseases are the most common of all autoimmune diseases. In the literature, Hashimoto thyroiditis (HT) is considered to be a T-helper (Th) type 1 dominant condition, and Graves disease is considered a Th2-dominant condition.

Objective: The aim of this study was to highlight a new aspect of the relationships among Th cell subgroups by determining the incidence of autoimmune thyroid disease in patients with allergic rhinitis (AR).

Renal tubular acidosis in renal transplant patients: the effect of immunosuppressive drugs.

Background: Renal tubular acidosis (RTA) is a non-anion gap metabolic acidosis and is generally mild and asymptomatic in kidney recipients. Calcineurine inhibitors (CNIs) increase the frequency of RTA but the frequency of RTA development in kidney transplant recipients receiving mammalian target of rapamycin inhibitors (mTORi) treatment remains unclear. In this study, we aimed to investigate the frequency of RTA in kidney transplant recipients on mTORi and CNI treatment and to compare both groups.

Relationship between epicardial adipose tissue, inflammation and volume markers in hemodialysis and transplant patients.

Cardiovascular (CV) diseases are still the most important cause of morbidity and mortality in both patients receiving hemodialysis (HD) treatment and individuals with renal transplantation (Rtx). Measurement of epicardial adipose tissue (EAT) thickness is an easily applied, cheap, and useful recent method predicting increased CV risk. We aimed to compare EAT changes in HD and Rtx patients and the association between EAT and inflammatory and CV volume markers in both groups.

Staphylococcal empyema secondary to IgA nephropathy.

A 27-year-old male patient, applied to the emergency unit with complaints of high fever, nausea, vomiting, and hematuria. In his physical examination, fever was 38 °C with normal findings in all other systems. The laboratory values were as follows: urea 58 mg/dL, creatinine 2.

The effect of cold ischemia time on delayed graft function and acute rejection in kidney transplantation.

The objective of this study is to evaluate the impact of cold ischemia time (CIT) on delayed graft function (DGF) and acute rejection (AR) among deceased donor kidney transplant recipients. The medical records of 111 patients who underwent kidney transplantation from deceased donors between November 1994 and July 2009 were retrospectively analyzed. DGF was observed in 54% of the patients and the prevalence of AR in the first year after transplantation was 9.

The relation between serum testosterone levels and cardiovascular risk factors in patients with kidney transplantation and chronic kidney disease.

The objective of the study is to evaluate the relationship between serum testosterone levels and cardiovascular risk factors (CVRF) in patients after kidney transplantation and with chronic kidney disease (CKD). Seventy-five male patients, aged between 18 and 68 years, who had kidney transplantation at least six months earlier, were enrolled into the study. Only renal transplant recipients and CKD patients with a creatinine level of <2.
