Background: Peritoneal dialysis-associated peritonitis is a common and severe complication of peritoneal dialysis, associated with high morbidity and mortality. However, there's a lack of research on refractory peritonitis, which is difficult to manage and has a poor prognosis. Our study aimed to investigate factors affecting clinical outcomes in peritoneal dialysis patients with refractory peritonitis over a 12-year period at a medical faculty hospital in Turkey.

Article Synopsis
  • Latent tuberculosis infection (LTBI) screening is essential for solid organ transplant (SOT) recipients, but many centers in Turkey are not adequately performing these screenings.
  • In a study involving 766 SOT patients, 46.9% tested positive for LTBI, but only about half of those treated were registered, and there was a low completion rate of treatment.
  • The findings highlight the need for better TB risk assessment and adherence to national guidelines to improve pre-transplant care for SOT recipients in Turkey.

Objectives: Sarcopenia is common in chronic kidney disease and associated with increased mortality. We investigated the prevalence of sarcopenia, defined as low muscle mass by the psoas muscle index, in endstage renal disease patients on waiting lists for kidney transplant and determined its association with prognostic nutritional index, C-reactive protein-toalbumin ratio, cardiovascular events, and mortality.

Materials And Methods: Our study included 162 patients with end-stage renal disease and 87 agematched healthy controls.

Article Synopsis
  • Kidney transplant (KT) recipients who receive transplants from HLA identical siblings (HLAid) have a lower immunological risk, but specific immunosuppression guidelines for them are lacking.
  • A systematic review analyzed 16 relevant studies involving 5636 HLAid KT recipients, focusing on different immunosuppression strategies and their effectiveness.
  • The findings revealed a poor quality of evidence regarding immunosuppression approaches, with most older studies and no strong conclusions linking immunosuppression to outcomes based on current immunological risk assessments.

Background: Atypical hemolytic syndrome (aHUS) and C3 glomerulopathy (C3G) are complement-mediated rare diseases with excessive activation of the alternative pathway. Data to guide the evaluation of living-donor candidates for aHUS and C3G are very limited. The outcomes of living donors to recipients with aHUS and C3G (Complement disease-living donor group) were compared with a control group to improve our understanding of the clinical course and outcomes of living donation in this context.

Living donation challenges the ethical principle of non-maleficence in that it exposes healthy persons to risks for the benefit of someone else. This makes safety, informed consent (IC) and education a priority. Living kidney donation has multiple benefits for the potential donor, but there are also several known short- and long-term risks.

Introduction: Data to guide the evaluation of living-related donor candidates for kidney transplant recipients with Alport syndrome (AS) spectrum are limited. We aimed to examine a cohort of living-related donors to recipients with AS and compare their outcomes with a control group to improve understanding of the clinical course and outcomes of living donation in this context.

Methods: Living donors (LDs) of AS recipients and propensity score-matched control LDs without any family history of AS (control group) were followed for major cardiac events, death, post-donation estimated glomerular filtration rate (eGFR), and proteinuria.

Objective: Although liver dysfunction is not considered the main organ involvement in Systemic Lupus Erythematosus (SLE), the frequency of liver dysfunction or abnormal liver enzyme values may be observed in 50-60% of patients. The aim of this study was to assess fatty liver and liver fibrosis in SLE patients using Fibroscan as well as determine associated factors such as immunosuppressive medications.

Methods: Sixty SLE patients and 30 healthy controls were included.

Article Synopsis
  • The Prognostic Nutritional Index (PNI) is an important marker for predicting mortality in elderly patients (over 80) with chronic kidney disease (CKD).
  • During a study of 359 patients, it was found that those with a low PNI (< 39) had higher mortality rates and lower levels of critical health markers like albumin and hemoglobin.
  • The findings suggest that PNI can effectively assess nutritional status and may help in monitoring and improving patient outcomes in this age group with CKD.
