Evaluation of Bone Mineral Metabolism in Pre-Dialysis Chronic Kidney Disease: Quantitative Computed Tomography vs. Dual-Energy Absorptiometry and Correlation with Bone Turnover Markers.

: Bone and mineral disease (BMD) is a prevalent complication of advanced chronic kidney disease (CKD). The risk of fractures can be assessed via dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT). This study aims to evaluate the effectiveness of two imaging modalities in identifying bone mineral status in individuals with pre-dialysis chronic renal disease and to assess their correlation with bone turnover markers.

Effects of Nutritional Protocol Changes on Hemodialysis Adequacy and Patient Health During the COVID-19 Pandemic.

BACKGROUND During the COVID-19 pandemic, strict feeding restrictions were implemented in many dialysis centers to minimize transmission between patients. This study aims to evaluate the effects of these feeding restrictions on dry weight, intradialytic hypotension (IDH), and dialysis adequacy in hemodialysis patients. MATERIAL AND METHODS In this retrospective single-center study involving 76 hemodialysis patients, data from 2 consecutive 6-month periods were analyzed: the first before the COVID-19 pandemic when intradialytic nutrition was supported, and the second during the pandemic when intradialytic nutrition was restricted.

Rhabdomyolysis-related acute kidney injury in patients with COVID-19.

Background: Viral and bacterial infections may be complicated by rhabdomyolysis, which has a spectrum of clinical presentations ranging from asymptomatic laboratory abnormalities to life-threatening conditions such as renal failure. Direct viral injury as well as inflammatory responses may cause rhabdomyolysis in the course of coronavirus disease 2019 (COVID-19). When presented with acute kidney injury (AKI), rhabdomyolysis may be related to higher morbidity and mortality.

Chronic Myeloid Leukemia in Renal Transplantation Patients in the Era of Tyrosine Kinase Inhibitors: A Case Report and Review of the Literature.

Lifelong immunosuppression, cytotoxic effects of some immunosuppressive drugs, and opportunistic oncogenic viruses increase malignancy risks in solid organ recipients. The risk of myeloid neoplasms including chronic myeloid leukemia (CML) is also increased in this patient population. Tyrosine kinase inhibitors (TKIs), the key element of CML therapy, should be used cautiously in transplantation patients as they may interact with calcineurin inhibitors.

A novel homozygous SLC12A3 mutation causing Gitelman syndrome with co-existent autoimmune thyroiditis: a case report and review of the literature.

Gitelman syndrome is a rare, autosomal recessively inherited tubulopathy manifesting with hypokalemia, hypomagnesemia, hypocalciuria, and metabolic alkalosis. Common symptoms include fatigue, myalgia, reduced performance capacity, tetany, paresthesia, and delayed growth. However, as reported in the literature, diagnosis in some patients is prompted by an incidental finding of hypokalemia.

A comparison of antibody response in kidney transplant recipients and healthcare workers who had PCR-confirmed COVID-19 infection.

Background: Data on antibody response following COVID-19 in kidney transplant recipients is scarce. This crosssectional study aims to investigate the antibody response to COVID-19 among kidney transplant recipients.

Methods: We recruited 46 kidney transplant recipients with RT-PCR-confirmed COVID-19 and 45 recipients without COVID-19 history.

Waning of SARS-CoV-2 Vaccine-Induced Immune Response over 6 Months in Peritoneal Dialysis Patients and the Role of a Booster Dose in Maintaining Seropositivity.

Introduction: Although lower than general population, newly developed SARS-CoV-2 vaccines generate immune responses in end-stage kidney disease patients. However, the persistence of immune responses in the long term is not known yet. This study aimed to evaluate humoral immune responses in peritoneal dialysis (PD) patients over 6 months and to analyze the effects of the booster dose.

Fluctuations in Interleukin-6 Levels during Hemodialysis Sessions with Medium Cutoff Membranes: An Analysis on COVID-19 Case Series.

Introduction: Interleukin-6 (IL-6) is one of the most important mediators of inflammation. It is also the culprit for a severe disease course in COVID-19. While COVID-19 has higher mortality in hemodialysis (HD) patients, medium cutoff (MCO) membranes were previously suggested as promising tools for better patient outcomes by purging inflammatory mediators.

Antibody responses to inactivated SARS-CoV-2 vaccine in peritoneal dialysis patients.

Introduction: As end-stage renal disease (ESRD) patients generally have reduced responses to the vaccines, effectiveness of newly developed SARS-CoV-2 vaccines in ESRD are also matters of curiosity. We aimed to investigate the humoral responses of our peritoneal dialysis (PD) patients to the inactivated SARS-CoV-2 vaccine.

Methods: Humoral immune responses of 23 PD patients who received two doses of the inactivated SARS-CoV-2 vaccine were investigated with a commercial test that measures IgG antibodies towards receptor binding domain of SARS-CoV-2 spike protein.

Antibody responses to the SARS-CoV-2 vaccines in hemodialysis patients: Is inactivated vaccine effective?

Introduction: Vaccines generally have reduced effectiveness in hemodialysis patients and a similar condition may also apply for the SARS-CoV-2 vaccines. The aim of this study was to analyze humoral responses of hemodialysis patients to SARS-CoV-2 vaccines.

Methods: Eighty-five maintenance hemodialysis patients who received either inactivated or mRNA SARS-CoV-2 vaccines were investigated.

Intraperitoneal vancomycin-induced immune thrombocytopenia.

Vancomycin is one of the drugs used in the peritonitis treatment regimen of peritoneal dialysis patients. Intraperitoneal route is generally preferred to provide rapid elimination of infective agents. Systemic toxicities of certain drugs after intraperitoneal administration are not very clear.

[Clinical Characteristics of Mild-Moderate COVID-19 Patients and Risk Factors for the Development of Pneumonia].

Limited data exists to date on the predictors for the development of pneumonia in patients with mild and moderate coronavirus (COVID-19). In this study, it was aimed to evaluate the demographic characteristics and clinical findings of mild and moderate COVID-19 and to determine the risk factors for the development of COVID-19 pneumonia in patients admitted to the pandemic outpatient clinic of a university hospital. A total of 414 patients with laboratory confirmed COVID-19 were included.

Arteriovenous fistula as the vascular access contributes to better survival of hemodialysis patients with COVID-19 infection.

Background: While COVID-19 in chronic hemodialysis patients has high mortality and the pandemic will not end in the near future, effective follow up strategies should be implemented for these patients. Surgeries have been triaged according to their level of urgencies and arteriovenous fistula (AVF) operations were among elective surgeries. This study aimed to analyze the effect of vascular access on the outcomes of hemodialysis patients who had COVID-19.

Seroprevalence of coronavirus disease 2019 (COVID-19) among health care workers from three pandemic hospitals of Turkey.

COVID-19 is a global threat with an increasing number of infections. Research on IgG seroprevalence among health care workers (HCWs) is needed to re-evaluate health policies. This study was performed in three pandemic hospitals in Istanbul and Kocaeli.

Medium Cut-Off Dialysis Membranes: Can They Have Impact on Outcome of COVID-19 Hemodialysis Patients?

Introduction: Severe acute respiratory syndrome coronavirus-2 may lead to high levels of expression of inflammatory cytokines. Medium cut-off (MCO) membranes may make greater clearances for large-middle molecules (including cytokines) than low-flux (LF) membranes. In this study, we aimed to evaluate the impact of MCO membranes on outcome of COVID-19 patients on hemodialysis (HD).

Sudden Cardiac Death in Haemodialysis Patients under Hydroxychloroquine Treatment for COVID-19: A Report of Two Cases.

Hydroxychloroquine (HQ) has been used for the treatment of novel coronavirus disease (COVID-19) even though there is no clear evidence for its effectiveness yet. In contrary, HQ has major side effects like QTc prolongation and subsequent development of ventricular arrhythmias. Such side effects may possess additional risks on end-stage renal disease (ESRD) patients who have higher cardiovascular risks than general population.

Kidney function on admission predicts in-hospital mortality in COVID-19.

Background: Recent data have suggested the presence of a reciprocal relationship between COVID-19 and kidney function. To date, most studies have focused on the effect of COVID-19 on kidney function, whereas data regarding kidney function on the COVID-19 prognosis is scarce. Therefore, in this study, we aimed to investigate the association between eGFR on admission and the mortality rate of COVID-19.
