RESUMO
BACKGROUND: Kidney transplant (KT) is the most common solid organ transplantation in the world. OBJECTIVE: To analyze the information from Mexico on KT, waiting lists (WL) and patients on dialysis between 2012 and 2019 and compare that of 2019 with those of the countries of the American Continent, Spain and Portugal. MATERIAL AND METHODS: The required information was obtained from the Global Observatory on Organ Donation and Transplantation (GODT). RESULTS: Between 2012 and 2019, the annual number of kidney transplants (KTs) in Mexico increased by 12.5%, while the WL by December 31 of each year did it by 86.1%. In 2019, Spain and the US reported the highest KT rates, while Mexico ranked 8th in the Pan-American and Iberian comparison, 6th in the American Continent and 4th in Latin America. Mexico did not report to GODT the number of patients on dialysis in 2019 and 2018. CONCLUSIONS: KTs should be considered an integral part of renal replacement therapies. The GODT reports include the numbers of patients on dialysis for each country. Mexico does not always report this data, probably due to the lack of a national registry of chronic kidney disease, the creation of which should be supported.
ANTECEDENTES: El trasplante renal (TR) es el trasplante de órgano sólido más frecuente en el mundo. OBJETIVO: Analizar la información de México sobre TR, listas de espera (LE) y pacientes en diálisis entre 2012-2019 y comparar la del año 2019 con la de los países del continente americano, España y Portugal. MATERIAL Y MÉTODOS: La información requerida se obtuvo del Global Observatory on Organ Donation and Transplantation (GODT). RESULTADOS: Entre 2012-2019 en México el número anual de trasplantes renales (TR) se incrementó en un 12.5%, mientras que la LE al 31 de diciembre de cada año lo hizo en un 86.1%. En 2019, España y EE.UU. reportaron las tasas más altas de TR, mientras que México ocupó el 8.° lugar en la comparativa panamericana e ibérica, 6.° en el Continente Americano y 4.° en América Latina. México no reportó al GODT el número de pacientes en diálisis en 2019 y 2018. CONCLUSIONES: Los TR deben considerarse parte integral de las terapias de reemplazo renal. Los reportes del GODT incluyen las cifras de pacientes en diálisis de cada país. México no siempre reporta este dato, probablemente por carecer de un registro nacional de enfermedad renal crónica, cuya creación debe apoyarse.

The environmental microbiological control is necessary to prevent infections associated with certain procedures that are performed at the hospital. In this review the procedures for control of water and dialysis fluids, and air in operating rooms and immunocompromised units are addressed. The dialysis quality management guidelines define the highest levels of chemical, microbiological and endotoxin in purified water and dialysis fluids based on the recommendations of scientific societies. The microbiological control of water and dialysis fluids should include detection of microorganisms and endotoxin levels. Regarding the microbiological air sampling of operating rooms and immunocompromised units the types of clean rooms in which is recommended to perform microbiological air monitoring; the sample collection methods; culture media; incubation conditions; the most common microorganisms, and permissible levels depending on the type of surgery are described.

OBJECTIVE: To determine the cost of the dialytic management of paediatric acute kidney injury in a low-income country. METHODS: All children under the age of 15 years, who had either peritoneal dialysis or haemodialysis for acute kidney injury in Aminu Kano Teaching Hospital over a 1-year period, were studied. The average cost of each dialysis modality was estimated. RESULTS: Of 20 children, who had dialysis for acute kidney injury, 12 (60%) had haemodialysis and 8 (40%) had peritoneal dialysis. The mean cost for haemodialysis exceeded that of peritoneal dialysis ($363.33 vs. $311.66, t = 1.04, P = 0.313) with the mean cost of consumables significantly accounting for most of the cost variation ($248.49 vs. $164.73, t = 2.91, P = 0.009). Mean costs of nephrologist visit and nursing were not found to be significant. CONCLUSION: Peritoneal dialysis is the less costly alternative for managing acute kidney injury in children in our environment.

INTRODUCTION: In January 2014 a possible outbreak of Burkholderia cepacia bacteremia occurred in a hemodialysis center situated in La Linea de la Concepción (Cadiz). An investigation was begun to confirm the outbreak, identify the source, and implement control measures. METHODS: A descriptive analysis was performed to describe the characteristics of the patients affected with Burkholderia cepacia bacteremia from November 2013 to February 2014. Environmental samples were taken. A molecular typing study was performed using pulsed field gel electrophoresis (SpeI PFGE) and MLST analysis in order to determine the genetic similarity between the isolates. RESULTS: The bacterium was isolated from blood cultures of 7 patients during the study period. Three of the samples (2 of which were also cases) were endoluminal fluid from catheter locks, and 4 chlorhexidine bottle samples. The patients were coincident in 2 of the 6 work shifts. The mean age of the cases was 67 years of whom 57% were women. Human samples and an environmental sample was analyzed and found to be genetically identical (ST653 clone). CONCLUSIONS: The analysis confirmed the outbreak of Burkholderia cepacia, with 7 cases among the patients of the hemodialysis center. The outbreak was due to the same strain, probably a common source and secondary transmission from person to person.

An evaluation of the characteristics of peritoneal solute and water transport is essential to assess the suitability of prescribing dialysis in patients suffering from chronic renal disease. There are currently a series of models to perform this evaluation. The peritoneal equilibration test (PET) evaluates the peritoneal transport capacity, classifying the patients into four transport categories: high, high-average, low-average, and low. The short PET enables the same evaluation to be made in only 2hours, and has been validated in paediatric patients. On the other hand, the MiniPET provides additional information by evaluating the free water transport capacity by the ultra-small pores, and the Accelerated Peritoneal Examination Time (APEX) evaluates the time when the glucose and urea equilibration curves cross, and has been proposed as the optimum dwell time to achieve adequate ultrafiltration. An analysis is presented on the current information on these diagnostic methods as regards free water transport via aquaporins, which could be an important tool in optimising solute and water transport in patients on chronic peritoneal dialysis, particularly as regards the cardiovascular prognosis.

INTRODUCTION: Hemolytic uremic syndrome (HUS) is characterized by the presence of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney failure. It is the leading cause of acute kidney failure in children under 3 years of age. A variable number of patients develop proteinuria, hypertension, and chronic renal failure. OBJECTIVE: To evaluate the renal involvement in pediatric patients diagnosed with HUS using the microalbumin/creatinine ratio. PATIENTS AND METHODS: Descriptive concurrent cohort study that analyzed the presence of microalbuminuria in patients diagnosed with HUS between January 2001 and March 2012, who evolved without hypertension and normal renal function (clearance greater than 90ml/min using Schwartz formula). Demographic factors (age, sex), clinical presentation at time of diagnosis, use of antibiotics prior to admission, and need for renal replacement therapy were evaluated. RESULTS: Of the 24 patients studied, 54% were male. The mean age at diagnosis was two years. Peritoneal dialysis was required in 45%, and 33% developed persistent microalbuminuria. Antiproteinuric treatment was introduce in 4 patients, with good response. The mean follow-up was 6 years (range 6 months to 11 years). The serum creatinine returned to normal in all patients during follow up. CONCLUSIONS: The percentage of persistent microalbuminuria found in patients with a previous diagnosis of HUS was similar in our group to that described in the literature. Antiproteinuric treatment could delay kidney damage, but further multicenter prospective studies are necessary.

INTRODUCTION AND OBJECTIVES: The efficacy of fluconazole as a prophylactic strategy in patients with chronic kidney disease (CKD) on peritoneal dialysis (PD) with prior antibiotic exposure is controversial in the current literature. This study aimed to compare a strategy of fluconazole prophylaxis versus no-prophylaxis for patients in PD on antibiotics for previous episodes of peritonitis. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs) comparing fluconazole prophylaxis with no prophylaxis for PD-related peritonitis. The search was conducted on PubMed, EMBASE, and Cochrane Central in January 23, 2023. The outcome of interest was the occurrence of fungal peritonitis (FP). RESULTS: We included six studies (1 RCT, 5 observational) with 4515 occurrences of peritonitis, of which 1098 (24.8%) received fluconazole prophylaxis in variable doses, whereas 3417 (75.6%) did not receive prophylaxis during peritonitis episodes. Overall, fluconazole prophylaxis was associated with a lower incidence of FP (OR 0.22; 95% CI 0.12-0.41; p<0.001; I2=0%). Subgroup analysis of studies that administered daily doses of fluconazole also demonstrated a reduced incidence of FP in patients who received antifungal prophylaxis (OR 0.31; CI 0.14-0.69; p=0.004; I2=0%). CONCLUSIONS: In this meta-analysis of 4515 episodes of PD-related peritonitis, prophylaxis with fluconazole significantly reduced episodes of FP as compared with no antifungal prophylaxis.

BACKGROUND: Patients with chronic kidney disease on hemodialysis (HD) often have cognitive deficits. However, there are few studies that have examined the neuropsychological impairments of patients receiving peritoneal dialysis (PD). METHODS: Executive functions, processing speed and verbal memory were assessed in 27 PD patients, 42 HD patients, and 42 healthy participants (HP). Systolic blood pressure and total time on renal replacement therapy (RRT) were controlled statistically. Associations between performance and clinical factors were analyzed using correlations and multiple regression. RESULTS: The DP group showed better performance compared to the HD group in verbal fluency, working memory, cognitive flexibility, planning and decision making. The DP group showed worse execution than the HP group in verbal inhibition and memory. Executive function scores were positively associated with total months on PD, total months on RRT, total months on HD, albumin, total cholesterol, and phosphorus, and negatively with ferritin. CONCLUSION: Global executive functioning was more optimal in PD patients than in HD patients. The results show the positive effect of PD on executive functions, which must be taken into account when choosing the TRS. The associations observed between biochemical factors and performance show the importance of maintaining an adequate nutritional status in these patients.

INTRODUCTION AND OBJECTIVES: Functional and durable vascular access is needed for adequate hemodialysis. Arteriovenous fistula is preferred over prosthetic grafts or central venous catheters, but it is associated with high rates of primary failure and maturation failure. Preoperative mapping of arm vessels with color Doppler ultrasound (CDU) has been shown to be helpful in achieving better short and long-term outcomes. Unfortunately, is more time-consuming than a physical examination and requires an experienced examiner and special equipment; some authors defend that CDU should not be part of the routine preoperative assessment. We reported our experience in preoperative vessel mapping using color Doppler ultrasound to purpose a vascular access to the surgical team, surveillance of vascular access, and evaluation of main outcomes (primary failure, maturation failure, and patency). METHODS: This is a single-center retrospective study that includes patients who attended a specific appointment for vascular access planning consultation between January 2019 and December 2021. A nephrologist performed the physical exam and vascular mapping and proposed to the vascular surgeon team a specific type and location of vascular access. Patients were followed until one month after the first hemodialysis through functioning vascular access. RESULTS: In this study, 167 patients were evaluated (114 incident patients - chronic kidney disease stage 4 or 5 - and 53 prevalent patients - under hemodialysis through central venous catheter). The vascular accesses proposed by nephrologist were radial-cephalic arteriovenous fistula in 70 patients (41.9%), brachio-cephalic arteriovenous fistula in 50 patients (29.9%), brachio-basilic arteriovenous fistula in 34 patients (20.4%), arteriovenous graft in 8 patients (4.8%) and central venous catheter in 2 patients (1.2%). Vascular access was constructed in 141 patients: distal arteriovenous fistula in 57 patients (40.4%), brachio-cephalic arteriovenous fistula in 54 patients (38.3%), brachio-basilic AVF in 27 patients (19.1%), and arteriovenous graft in 3 patients (2.1%). The created access corresponds to the proposed access in 129 patients (91.5%). Twenty-two (15.6%) primary failures were registered. Distal arteriovenous fistulas and diabetes mellitus were associated with a higher risk of primary failure (OR=3.929 (1.485-10.392), p=0.004; OR=3.867 (1.235-12.113), p=0.014, respectively). The incidence of maturation failure at eight weeks was 4.8%. The primary patency at 6, 12 and 24 months was 76.3%, 70.4% and 49.2%. Primary assisted patency was 84.8% at 6 and 12 months and 81.3% at 24 months. CONCLUSIONS: This study demonstrates that the study of the entire vascular territory performed with color Doppler ultrasound, within a multidisciplinary team of nephrologists and vascular surgeons, is associated with high rates of autologous access and very low rates of primary failure and maturation failure (almost unprecedented in the literature).

Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillars for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1,403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% or in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scores used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.

INTRODUCTION AND OBJECTIVES: Diabetes, dyslipidemia, older age, gender, urinary tract infections, and recent antibiotic intake have been associated with a decrease in the urobiome richness and other fluctuations in this microbiome. Gut and blood microbiome have been reported to be altered in patients with chronic kidney disease (CKD), and specifically in peritoneal dialysis (PD) patients. Still, there are currently no studies describing the urogenital microbiome in CKD-PD patients. In this study we characterized the urobiome profile in 46 PD patients and analyzed its clinical and inflammatory parameters. MATERIALS AND METHODS: Mid-stream urine, fecal and blood samples were collected from 46 patients undergoing PD at Centro Hospitalar Universitário de São João (CHUSJ) in Porto, Portugal. Exclusion criteria were age under 18 years old, inability to give informed consent, history of infection in the last three months, and antibiotic intake in the last three months. The microbiome communities were analyzed by amplification and sequencing of the V3-V4 region of the bacterial 16S rRNA gene. Correlations with the patients' clinical data and inflammatory profile were performed. RESULTS: CKD-PD patients presented a unique urobiome profile dominated by Bacillota, Actinomycetota and Pseudomonadota and characterized by a lower Shannon diversity than fecal and blood microbiome. The taxonomic profiles of urogenital samples were organized in multiple subtypes dominated by populations of Lactobacillus, Staphylococcus, Streptococcus, Gardnerella, Prevotella, Escherichia-Shigella, being similar to other non-PD-CKD patients. Gender, sCD14, residual diuresis and history of peritonitis were significantly associated to variations in the urobiome. Although not reaching statistical significance, diabetes and the time on PD also showed association with particular taxonomic groups. Depletion of Gardnerella, Staphylococcus, Corynebacterium, Lactobacillus or Dermabacter populations correlated with CKD-PD patients with history of diabetes, history of peritonitis and altered levels of sCD14. CONCLUSIONS: Our results highlight urogenital microbiome as a potential partner and/or marker in the overall health state of CKD-PD patients.

INTRODUCTION: In some studies, the peritoneal solute transfer rate (PSTR) through the peritoneal membrane has been related to an increased risk of mortality. It has been observed in the literature that those patients with rapid diffusion of solutes through the peritoneal membrane (high/fast transfer) and probably those with high average transfer characterized by the Peritoneal Equilibrium Test (PET) are associated with higher mortality compared to those patients who have a slow transfer rate. However, some authors have not documented this fact. In the present study, we want to evaluate the (etiological) relationship between the characteristics of peritoneal membrane transfer and mortality and survival of the technique in an incident population on peritoneal dialysis in RTS Colombia during the years 2007-2017 using a competing risk model. MATERIALS AND METHODS: A retrospective cohort study was carried out at RTS Colombia in the period between 2007 and 2017. In total, there were 8170 incident patients older than 18 years, who had a Peritoneal Equilibration Test (PET) between 28 and 180 days from the start of therapy. Demographic, clinical, and laboratory variables were evaluated. The (etiological) relationship between the type of peritoneal solute transfer rate at the start of therapy and overall mortality and technique survival were analyzed using a competing risk model (cause-specific proportional hazard model described by Royston-Lambert). RESULTS: Patients were classified into four categories based on the PET result: Slow/Low transfer (16.0%), low average (35.4%), high average (32.9%), and High/Fast transfer (15.7%). During follow-up, with a median of 730 days, 3025 (37.02%) patients died, 1079 (13.2%) were transferred to hemodialysis and 661 (8.1%) were transplanted. In the analysis of competing risks, adjusted for age, sex, presence of DM, HTA, body mass index, residual function, albumin, hemoglobin, phosphorus, and modality of PD at the start of therapy, we found cause-specific HR (HRce) for high/fast transfer was 1.13 (95% CI 0.98-1.30) pâ¯=â¯0.078, high average 1.08 (95% CI 0.96-1.22) pâ¯=â¯0.195, low average 1.09 (95% CI 0.96-1.22) pâ¯=â¯0.156 compared to the low/slow transfer rate. For technique survival, cause-specific HR for high/rapid transfer of 1.22 (95% CI 0.98-1.52) pâ¯=â¯0.66, high average HR was 1.10 (95% CI 0.91-1.33) pâ¯=â¯0.296, low average HR of 1.03 (95% CI 0.85-1.24) pâ¯=â¯0.733 compared with the low/slow transfer rate, adjusted for age, sex, DM, HTA, BMI, residual renal function, albumin, phosphorus, hemoglobin, and PD modality at start of therapy. Non-significant differences. CONCLUSIONS: When evaluating the etiological relationship between the type of peritoneal solute transfer rate and overall mortality and survival of the technique using a competing risk model, we found no etiological relationship between the characteristics of peritoneal membrane transfer according to the classification given by Twardowski assessed at the start of peritoneal dialysis therapy and overall mortality or technique survival in adjusted models. The analysis will then be made from the prognostic model with the purpose of predicting the risk of mortality and survival of the technique using the risk subdistribution model (Fine & Gray).

INTRODUCTION: The influence of socioeconomic and cultural barriers in the choice of renal replacement therapy (RRT) techniques in advanced chronic kidney disease (ACKD) has been scarcely explored, which can generate problems of inequity, frequently unnoticed in health care. The aim of this study is to identify the "non-medical" barriers that influence the choice of RRT in an advanced chronic kidney disease (ACKD) consultation in Spain. MATERIAL AND METHODS: Retrospective analysis including the total number of patients seen in the ACKD consultation in a tertiary hospital from 2009 to 2020. Inclusion in the ACKD consultation began with an eligibility test and a decision-making process, conducted by a specifically trained nurse. The variables considered for the study were: age, sex, etiology of CKD, level of dependence for basic activities of daily living (Barthel Scale) and instrumental activities of daily living (Lawton and Brody Scale), Spanish versus foreign nationality, socioeconomic level and language barrier. The socioeconomic level was extrapolated according to home and health district by primary care center to which the patients belonged. RESULTS: A total of 673 persons were seen in the ACKD consultation during the study period, of whom 400 (59.4%) opted for hemodialysis (HD), 156 (23.1%) for peritoneal dialysis (PD), 4 (0.5%) for early living donor renal transplantation (LDRT) and 113 (16.7%) chose conservative care (CC). The choice of PD as the chosen RRT technique (vs. HD) was associated with people with a high socioeconomic level (38.7% vs. 22.5%) (pâ¯=â¯0.002), Spanish nationality (91% vs. 77.7%) (pâ¯<â¯0.001), to a lower language barrier (0.6% vs 10.5%) (pâ¯<â¯0.001), and to a higher score on the Barthel scale (97.4 vs 92.9) and on the Lawton and Brody scale (7 vs 6.1) (pâ¯<â¯0.001). Neither age nor sex showed significant differences in the choice of both techniques. Patients who opted for CC were significantly older (81.1 vs 67.7 years; pâ¯<â¯0.001), more dependent (pâ¯<â¯0.001), with a higher proportion of women (49.6% vs 35.2%; pâ¯=â¯0.006) and a higher proportion of Spaniards (94.7% vs 81%, pâ¯=â¯0.001) in relation to the choice of other techniques (PD and HD). Socioeconomic level did not influence the choice of CC. CONCLUSION: Despite a regulated decision-making process, there are factors such as socioeconomic status, migration, language barrier and dependency of the population that influence the type of RRT chosen. To address these aspects that may cause inequity, an intersectoral and multilevel intervention is required with interdisciplinary teams that include, among others, social workers, to provide a more holistic and person-centered assessment.
RESUMO
INTRODUCTION AND OBJECTIVES: To minimize our peritoneal dialysis (PD) population exposure to coronavirus disease (COVID-19), in April 2020 we developed and implemented a telemedicine program. In this investigation, we aimed to compare the hospitalization rates and metabolic disorders in patients undergoing PD 6 months before and after the COVID-19 pandemic and telemedicine implementation. MATERIALS AND METHODS: This single-center retrospective analysis included all active prevalent patients undergoing PD from April 2020. Dialysis records were reviewed to obtain clinical, demographic, laboratory, appointment, and hospitalization data. We compared hospitalization rates (total, non-PD-related, and PD-related), hospitalization-associated factors, and metabolic disorders (hemoglobin, serum potassium, and serum phosphate) 6 months before and after the pandemic. RESULTS: Our sample comprised 103 participants. During the pre-pandemic and post-pandemic periods, there were 13 and 27 hospital admissions, respectively. The total hospitalization incident rate ratio (IRR) was 2.48 (95% confidence interval [CI], 1.29-4.75). PD-related hospitalizations increased from 3 to 15 episodes (IRR=7.25 [95% CI, 2.11-24.78]). In the pre-pandemic period, the educational level was lower in participants hospitalised due to PD-related issues than in participants not hospitalised. In the post-pandemic period, only sex distribution differed between patients not hospitalised and those hospitalised due to non-PD-related issues. Only serum potassium levels changed significantly in the post-pandemic period (4.79±0.48 vs. 4.93±0.54mg/dL; P<0.01). CONCLUSION: This study showed a significant increase in hospitalization rates after the COVID-19 pandemic period and telemedicine implementation, mainly due to PD-related infectious causes. Strategies to improve distance monitoring assistance are needed for the PD population.
RESUMO
INTRODUCTION: Pruritus associated with chronic kidney disease is defined as the sensation of itching, in people with chronic kidney disease, in a one area or all over the body that causes the need to scratch, after having ruled out other dermatological or systemic causes. It is an old and known problem whose prevalence has been able to decrease with the improvement of dialytic techniques but which still persists and is underdiagnosed. OBJECTIVES: The objective of this study was to analyse the current perception of nephrologists about this problem that influences the quality of life of people with chronic kidney disease through a survey. RESULTS: 135 nephrologists, most of them engaged in haemodialysis, participated. 86% considered that pruritus associated with chronic kidney disease is still a problem today that affects the quality of life. Most nephrologists believe that the main pathophysiological cause is uremic toxins (60%) and only 16% believe that it is due to the dysregulation of the opioid system/endorphins-dynorphins. Only 16% comment that the prevalence of pruritus in their centre is greater than 20%. 40% believe that the diagnosis is made because it is manifested by the patient and only 27% because it is asked by the doctor. Moreover, it is not usual to use scales to measure it or the codification in the medical records. The main treatment used is antihistamines (96%), followed by moisturizers/anaesthetics (93%) and modification of the dialysis regimen (70%). CONCLUSIONS: Pruritus associated with chronic kidney disease is still a current problem, it is underdiagnosed, not codified and with a lack of indicated, effective and safe treatments. Nephrologists do not know its real prevalence and the different pathophysiological mechanisms involved in its development. Many therapeutic options are used with very variable results, ignoring their efficacy and applicability at the present time. The new emerging kappa-opioid-receptor agonist agents offer us an opportunity to reevaluate this age-old problem and improve the quality of life for our patients with chronic kidney disease.

Background: COVID-19 challenged our health system, within the broad clinical spectrum acute kidney injury was presented as a catastrophic event, acute kidney injury and the risk of dependency after dialysis constitute a clinical problem with high repercussions in the funcionality. Objective: To identify risk factors for dialysis dependence after acute kidney injury from COVID-19. Material and methods: A retrospective observational cohort study was carried out at the Hospital de Especialidades del Centro Médico Nacional Siglo XXI, of the Mexican Institute of Social Security, from March 2020 to March 2021. 317 patients were included, we performed descriptive statistics, we compared differences between the stages of acute kidney injury, finding a difference in obesity with a frequency of 2.2% in stage 1, 20.82% stage 2 and 14.51% stage 3, with p value = 0.018. Results: We found dialysis dependence one year after hospital-acquired acute kidney injury induced by COVID-19 in 58 patients (18.9%), we analyzed by KDIGO stage, in those patients who had AKI KDIGO 1 (2.83%) it depended on dialysis at one year, in the KDIGO stage 2 (3.78%), in the KDIGO stage 3 (11.67%). Conclusions: Our study allowed us to identify that the risk factors associated with dialysis dependence are: male gender, type 2 diabetes mellitus, obesity, cardiovascular disease.

INTRODUCTION: Despite the benefits of physical exercise (PE) for patients with chronic kidney disease (CKD), the number of Nephrology services that have PE programs is limited. OBJECTIVES: To describe the degree of knowledge of PE benefits in patients with CKD among professionals, as well as the level of implementation and characteristics of PE programs in Nephrology services in Spain. METHODS: A questionnaire on the degree of knowledge and prescription of PE in patients with CKD was designed and sent to members of the Spanish Nephrology and Nephrology Nursing Societies, as well as to physiotherapists and professionals in the Sciences of Physical Activity and Sport (PASS). RESULTS: 264 professionals participated. 98.8% agreed on the importance of prescribing PE, but only 20.5% carry out an assessment of functional capacity and 19.3% have a PE program for patients with CKD in their centre. The most frequent programs are performed for haemodialysis patients and strength and aerobic resistance exercises are combined. A physiotherapist or a PASS usually participates in its prescription. The main barriers were the absence of human and/or physical resources and the lack of training. CONCLUSIONS: Healthcare workers know the benefits of PE in patients with CKD. However, the implementation of these programs in Spain is low, motivated by the lack of resources and training of professionals. We must establish strategies to guarantee an adequate functional capacity within the care of our patients.

INTRODUCTION: The sodium gradient during hemodialysis sessions is one of the key factors in sodium balance in patients with dialysis-dependent chronic kidney disease; however, until the appearance of the new monitors with sodium modules, the differences between prescribed and measured sodium have been understudied. The present study aimed to compare the impact on the measured conductivity and the initial and final plasma sodium after changing the 5008 Cordiax to the new 6008 Cordiax monitor. MATERIAL AND METHODS: 106 patients on hemodialysis were included. Each patient underwent 2 dialysis sessions in which only the monitor was varied. The variables collected were dialysate, sodium and bicarbonate prescribed, real conductivity, initial and final plasma sodium measured, and the calculated sodium gradient (ΔPNa). RESULTS: The change of dialysis monitor showed small but statistically significant differences in the initial (138.14mmol/L with 5008 vs. 138.81mmol/L with 6008) and final plasma sodium (139.58mmol/L vs. 140.97mmol/L), as well as in the actual conductivity obtained (13.97 vs. 14.1mS/cm). The ΔPNa also increased significantly. CONCLUSION: The change from 5008 to 6008 monitor is associated with increased conductivity, leading the patient to end the sessions with higher plasma sodium and ΔPNa. Knowing and confirming this change will allow us to individualize the sodium prescription and avoid possible undesirable effects. It could be the preliminary study to explore the new sodium biosensor incorporated into the new generation of monitors.

BACKGROUND AND OBJECTIVE: Studies on the prevalence of anaemia in chronic kidney disease in adults not on dialysis (CKD-ND) and in dialysis programmes (CKD-D) in Spain are not recent or focus on certain subgroups. The aim of this study was to know the epidemiology and current treatment patterns of anaemia associated with CKD in Spain. MATERIALS AND METHODS: Multicentre, non-interventional, retrospective study with CKD-ND stage 3a-5 and CKD-D patients treated in Spain between 2015 and 2017 (RIKAS study). RESULTS: The prevalence of anaemia in CKD-ND and CKD-D in 2015 was 33.8% and 91.5%, respectively, with similar results during 2016-2017. The prevalence of systemic inflammation in anaemic patients (18.1% and 51.8% for CKD-ND and CKD-D, respectively) was higher, especially in those treated with erythropoiesis-stimulating agents (ESA), compared to the general population with CKD-ND. After 12 months of follow-up, mean ferritin and transferrin saturation index (TSI) values in anaemic patients with CKD-ND were 187.1 ng/mL and 22.2%, respectively, while in CKD-D were 254.6 ng/mL and 20.2%. In ESA-treated patients, mean values were 190.6 ng/mL and 22.0% in ND-CKD, and 255.0 ng/mL and 20.2% in D-CKD. CONCLUSIONS: The prevalence of anaemia and inflammation increased with the disease severity, being higher in D-CKD. Iron parameters in anaemic patients treated or not with ESA are insufficient according to the guidelines, so there is room for improvement in the treatment of anaemia associated with CKD.

BACKGROUND: The associated factors of peritoneal small solute transport was not fully understood. This research aimed to investigate the connection between dialysate inflammatory markers (e.g. macrophage migration inhibitory factor, MIF) in peritoneal dialysis (PD) effluent and peritoneal solute transport rate (PSTR) properties. SUBJECTS AND DESIGN: A total of 80 stable PD patients in the First ShaoYang Hospital were enrolled in present study. Overnight PD effluent and serum inflammatory markers including MIF, MCP-1, VEGF, IL-6, TNFα and TGFß were detected. Pearson correlation analysis and Logistic regression was performed to determine the risk factors for the increased PSTR. RESULTS: A trend toward increased values of MIF, MCP-1 and IL-6 in PD effluent was observed in subjects with high PSTR when compared with those with low PSTR. The Pearson correlation test showed that D/P Cr exhibited positive correlations with dialysis effluent MIF (r=0.32, p=0.01), MCP-1 (r=0.47, p=0.01), IL-6 (r=0.48, p=0.01). Conversely, no significant correlation was found between D/P Cr and TGF-ß (r=0.04, p=0.70), TNF-É (r=0.22, p=0.05), VEGF (r=0.02, p=0.86) and serum inflammatory markers. In the unadjusted regression analysis, dialysis effluent MIF (OR 2.41), MCP-1 (OR 1.72), IL-6 (OR 1.55) were associated with high PSTR condition. Multivariate logistic regression analysis showed that the adjusted odds ratios (OR) of dialysis effluent MIF for high PSTR were 2.47 in all subjects (p=0.03). CONCLUSION: Elevated MIF, MCP-1 and IL-6 levels in PD effluent were associated with increased PSTR. Elevated dialysis effluent MIF levels was an independent risk factor for high PSTR in subjects with PD treatment.
