Introduction: The age for kidney transplantation (KT) is no longer a limitation and several studies have shown benefits in the survival of elderly patients. The aim of this study was to examine the relationship of the baseline Charlson comorbidity index (CCI) score to morbidity and mortality after transplantation.

Methods: In this multicentric observational retrospective cohort study, we included patients older than 60 years admitted on the waiting list (WL) for deceased donor KT from January 01, 2006, to December 31, 2016.

Article Synopsis
  • - The Argentine Registry of COVID in chronic dialysis reported data from April 2020 to April 2021, registering 36,918 patients on dialysis, with 10% (3,709) confirmed COVID-19 cases.
  • - Of those infected, 45.2% were hospitalized, with 39% requiring ICU care, and 62% of ICU patients needing mechanical ventilation; the overall death rate was 35.24%.
  • - Factors linked to higher mortality in dialysis patients included age over 60, diabetes, extended dialysis duration, and the necessity for hospitalization or ICU admission, indicating a critical need for focused care and vaccination strategies in this high-risk group.

The COVID-19 pandemic declared in March 2020, has generated worldwide concern due to its effect on the health of the population and the potential health collapse. The strategy of "flattening the curve" through social distancing made it possible to adapt the resources of the health system to patients with COVID-19, but results in other areas of health could not be predicted. The objective of this work was to analyze the consequences of the pandemic on liver transplantation in general and for hepatocarcinoma (HCC).

Background: The impact of renal transplantation (RT) in the elderly with many comorbid conditions is a matter of concern. The aim of our study was to assess the impact of RT on the survival of patients older than 60 years compared with those remaining on the waiting list (WL) according to their comorbidities.

Methods: In this multicentric observational retrospective cohort study, we included all patients older than 60 years old admitted on the WL from 01 January 2006 to 31 December 2016.

Background: The outcome of patients who return to dialysis after Kidney allograft failure (KAF) remains unclear. Our aim was to compare the outcome of KAF patients vs two different types of transplant naive incident dialysis (TNID) patients, those on the waiting list (WL) and those with a kidney transplant contraindication (KTC).

Methods: We performed an observational study using data from the Argentinian Dialysis Registry between 2005 and 2016.

Kidney Donor Profile Index (KDPI), derived from donor characteristics, was developed in the United States in an effort to devise an objective means of assessing donor organ suitability based on predicted graft survival. The objective of this study is to analyze the utility of KDPI to predict renal graft survival in Argentina. We conducted a retrospective national cohort study of adult patients who received a deceased donor renal transplantation in Argentina between January 2008 and December 2017.

Introduction And Aim: Liver transplantation (LT) for acute liver failure (ALF) still has a high early mortality. We aimed to evaluate changes occurring in recent years and identify risk factors for poor outcomes.

Material And Methods: Data were retrospectively obtained from the Argentinean Transplant Registry from two time periods (1998-2005 and 2006-2016).

In July 2005, Argentina switched from a categorical liver allocation system to a MELD/PELD-based policy for patients with CLD. To analyze WL outcomes and survival after LT in children. From January 2000 to December 2010, 923 children were registered.

Organ shortage is the major limitation for the growth of deceased donor liver transplant worldwide. One strategy to ameliorate this problem is to maximize the liver utilization rate. To assess predictors of liver utilization in Argentina.

Background: The development of intestinal transplant (Tx) programs introduces thymoglobulin donor treatment as well as an almost complete warm dissection of the abdominal organs to allocate them to different recipients. Our aim is to assess the reproducibility and feasibility of the surgical technique of multi-organ procurement with the use of thymoglobulin donor pre-treatment and report the short- and long-term outcomes of every graft harvested as part of multi-organ procurement (MTOp), including the intestine.

Methods: Data were collected of all organs harvested from MTOp, including the intestines allocated to our center from March 2006 to July 2011.

Background: A significant increase in the number of patients starting chronic hemodialysis (HD) with an estimated glomerular filtration rate (eGFR)≥10 mL/min/1.73 m(2) was observed in Argentina between 2004 and 2009.

Methods: In order to study this topic, we calculated the mortality hazard ratios (HR) in a cohort of incident HD individuals from the Argentine Registry of Chronic Dialysis [Registro Argentino de Diálisis Crónica] (2004-2009), grouped according to the initial eGFR (0-4.

In July 2005, Argentina became the first country after the United States to introduce the Model for End-Stage Liver Disease (MELD) for organ allocation. In this study, we investigated waiting-list (WL) outcomes (n = 3272) and post-liver transplantation (LT) survival in 2 consecutive periods of 5 years before and after the implementation of a MELD-based allocation policy. Data were obtained from the database of the national institute for organ allocation in Argentina.

Background: With improvements in short-term kidney graft and patient survival, focus has shifted to understand patient and graft features that affect long-term survival.

Materials And Methods: This retrospective analysis from January 1998 to December 2009 employed Kaplan-Meier analysis to evaluate survival ratios at 30 days as well as 1, 5, and 10 years. A multivariable Cox regression model considered variables of donor and recipient, gender and age, cold ischemia time (CIT), chronic renal failure etiology, time on dialysis (TD) and cause of donor death.

Introduction: Comparison of survival after renal transplant patients on the waiting list is an important factor to evaluate this therapy.

Objective: To measure the magnitude of deceased donor kidney transplant on patient survival compared to patients on dialysis and on waiting lists in over 18 years in Argentina.

Material And Methods: The information was obtained from SINTRA for the period January 2003 to December 2009.

Background: Thanks to advances in surgical techniques and immune system suppression, the mortality rate in children with end-stage renal disease (ESRD) has dramatically declined. Kidney transplantation has become the primary method to treat ESRD in the pediatric population.

Materials And Methods: Information was obtained from SINTRA (National Information System of Orrgan Procurement and transplantation in Argentina) for the period 1998-2009.

Introduction: Poor socioeconomic status in the patient population is one of the causes of the lack of primary and secondary prevention of chronic kidney disease and negatively affects the survival of patients on chronic haemodialysis (HD).

Objective: To confirm whether the low or absent income of the incident population on HD is a factor of poor prognosis.

Methods: We used the incident HD population of the Argentine Registry of Chronic Dialysis.

Background: In 2005, the model of end-stage liver disease (MELD)-based allocation system was adopted to assess potential liver transplant (LT) recipients in Argentina. The aim of the present study was to revise the activity of the MELD Exception Experts Committee.

Methods: Between 2005 and 2009, 1623 patients were listed for LT.

Children on continuous ambulatory peritoneal dialysis (CAPD) have a higher incidence of dialysate leakage than patients receiving cycler dialysis. To date, fibrin glue has been used to treat dialysate leakage but not as a method of prevention. Therefore, we conducted a prospective study in which 20 catheters were implanted in 19 children, with each catheter randomly assigned to either the treatment group (1 mL of fibrin glue added to peritoneal cuff suture) or the control group.
