Background: Kidney transplantation is the treatment of choice for end-stage renal disease that restores the patients' quality of life and reduces the morbidity and mortality rates induced by renal failure and its complications. However, after transplantation the organ and patient survival rates are important issues of interest in many centers worldwide.
Subjects And Methods: This is a historical cohort study planned to determine the organ survival rate after kidney transplantation from deceased donor during a period of 10 years (March 1999-March 2009) in Shiraz Transplant Center, Namazi Hospital, Shiraz, Iran. We tried to clarify the probable contributory risk factors implicating in graft loss. Kaplan-Meier method was used to determine the survival rate. Log-rank test was used to compare survival curves, and Cox regression model to define the hazard ratio and for modeling of factors implicating in survival rate.
Results: Mean follow-up period was 37.54 +/- 28.6 months. Allograft survival rates at 1, 3, 5, and 9 years after kidney transplantation from deceased donor (calculated by Kaplan-Meier method) was found to be 93.7, 89.1, 82.1, and 80.1%, respectively. Duration of dialysis before operation and creatinine level at discharge were showed to be the most important factors influencing survival rate of renal allograft.
Conclusion: Overall long-term graft survival in our cohort is satisfactory and comparable with reports from large centers in the world. Duration of dialysis before operation and creatinine level at discharge are the only independent factors that could correlate with long-term graft survival in our cohort.

Purpose Of The Review: Calcineurin inhibitors (CNIs) are central to immunosuppression in kidney transplantation (KT), improving short-term outcomes but falling short in enhancing long-term outcomes due to cardiovascular, metabolic, and renal complications. Belatacept, an FDA-approved costimulation blocker, offers a less toxic alternative to CNIs but is limited by its intravenous administration and reduced efficacy in high-immunological-risk patients.
Recent Findings: Emerging therapies target more specific pathways to improve efficacy and accessibility.

Preclinical and clinical xenotransplantation trials have shown that successful outcomes depend on a number of factors including the prevention of xenozoonoses. Preclinical trials involving pig kidneys and hearts transplanted into various non-human primates have revealed the potential impact of pig pathogens being present in the transplanted organ/tissue, mainly viruses. The concept of "designated pathogen-free donor animals" was developed to ensure elimination of pathogens during the breeding of donor animals to mitigate this occurrence.

Introduction: End-stage renal failure has negative effects on sexual life, and solid kidney transplantation helps to recovery in sexuality. However, recovery in sexual life progresses slowly, and female recipients may need spousal support during this process. To examine the perceived spousal support and sexual lives of female kidney recipients in the aim of this study.

Aim And Background: A combination of terlipressin and albumin is the standard of care for patients with hepatorenal syndrome-acute kidney injury (HRS-AKI). The study aimed to compare the venous congestion using lung ultrasound score (LUS) and radiographic assessment of lung edema (RALE) scores among terlipressin responders and nonresponders and survivors and non-survivors.
Materials And Methods: In this single-center, prospective, observational study, we included adult patients with HRS-AKI who had received terlipressin and albumin from 28th April 2022 to 16th October 2022.

Background: Lysinuric protein intolerance is a rare autosomal disorder caused by mutations in the Slc7a7 gene that lead to impaired transport of neutral and basic amino acids. The gold standard treatment for lysinuric protein intolerance involves a low-protein diet and citrulline supplementation. While this approach partially improves cationic amino acid plasma levels and alleviates some symptoms, long-term treatment is suggested to be detrimental and may lead to life-threatening complications characterized by a wide range of hematological and immunological abnormalities.
