RESUMO

In March 2020, a 74-year-old man affected by end-stage renal disease and on peritoneal dialysis was referred to an emergency room in Modena, Northern Italy, due to fever and respiratory symptoms. After ruling out COVID-19 infection, a diagnosis of chronic obstructive pulmonary disease exacerbation was confirmed and he was thus transferred to the nephrology division. Physical examination and blood tests revealed a positive fluid balance and insufficient correction of the uraemic syndrome, although peritoneal dialysis prescription was maximised. After discussion with the patient and his family, the staff decided to start hybrid dialysis, consisting of once-weekly in-hospital haemodialysis and home peritoneal dialysis for the remaining days. He was discharged at the end of the antibiotic course, after an internal jugular vein central venous catheter placement and the first haemodialysis session. This strategy allowed improvement of depuration parameters and avoidance of frequent access to the hospital, which is crucial in limiting exposure to SARS-CoV-2 in an endemic setting.

RESUMO

The use of tunneled cuffed catheters (TCCs) for permanent blood access is increasing as the hemodialysis population ages. However, the higher mortality and complication rates associated with their use have been significant concerns. This single-center observational cohort study aimed to investigate clinical factors affecting mortality and complications in Japanese hemodialysis patients with a TCC.We enrolled 64 consecutive patients receiving hemodialysis through a TCC between 2012 and 2019. The primary outcome was all-cause mortality and the secondary outcome was the incidence of catheter-related complications at 2 years. Cox proportional hazards models were used to examine variables associated with these outcomes.At 2 years, death from any cause and catheter-related complications occurred in 27/64 (42%) and 23/64 (36%) patients, respectively. There were 14 bacteremia events, 7 catheter obstructions, and 8 instances of restricted blood flow. Multivariate analysis showed that systolic blood pressure (SBP) < 100 mm Hg at the time of catheter insertion was associated with higher all-cause mortality (hazard ratio, 2.59; 95% confidence interval, 1.05-6.41) and catheter-related complications (hazard ratio, 2.57; 95% confidence interval, 1.52-22.2). The Kaplan-Meier analyses also showed that patients with SBP <100 mm Hg had higher mortality (P = .001) and a higher incidence of catheter-related complications (P = .0068).SBP <100 mm Hg at the time of catheter insertion is associated with mortality and catheter-related complications in hemodialysis patients using a TCC. Further multi-center studies are required to validate our results.

RESUMO

RATIONALE: Intestinal tuberculosis (TB) is rarely seen in patients with end-stage renal disease (ESRD). We report an intestinal TB case with a clinical presentation similar to that of colon cancer in a patient with ESRD on hemodialysis. PATIENT CONCERNS: A 49-year-old man presented with a 3-month history of general weakness and anorexia. He had been treated for stage 5 chronic kidney disease (CKD) due to diabetic nephropathy for the last 3 years. His blood urea nitrogen and serum creatinine levels were 96.9 and 8.1 mg/dL, respectively, at the time of admission; azotemia was accompanied by severe anemia, hypoalbuminemia, hyperkalemia, and metabolic acidosis. Hemodialysis was initiated for suspected exacerbation of uremia; however, intermittent fever, night sweats, and abdominal discomfort persisted. DIAGNOSES: Abdominal computed tomography (CT) and whole-body F-fluorodeoxyglucose positron emission tomography were indicative of ascending colon cancer with lymph node metastases. However, colonoscopy with biopsy revealed the formation of submucosal caseating granuloma and acid-fast bacillus. INTERVENTIONS: We initiated quadruple therapy with isoniazid, rifampicin, pyrazinamide, and ethambutol. The patient continued the quadruple regimen for the first 2 months before switching to dual therapy and received anti-TB medications for a total of 12 months. OUTCOMES: After 9 months of standard anti-TB chemotherapy, polypoid residual lesions were noted during follow-up colonoscopy. Laparoscopy-assisted ileocecal resection was performed. No findings suggestive of recurrence of colonic TB were observed on follow-up abdominal CT at 6 months after discontinuation of anti-TB medications. LESSONS: If non-specific uremic symptoms persist in patients with advanced CKD, the possibility of extrapulmonary TB such as intestinal TB must be considered. Also, in patients with radiologic suspicion of colon cancer, endoscopy with biopsy should be performed promptly to exclude colonic TB with similar clinical manifestations.

RESUMO

BACKGROUND: Proper care of young children in need of kidney transplant (KT) requires many skilled professionals and an expensive hospital structure. Small children have lesser access to KT. METHODS: We describe a strategy performed in Brazil to enable and accelerate KT in children ≤15 kg based on the establishment of one specialized transplant center, focused on small children, and cooperating with distant centers throughout the country. Actions on 3 fronts were implemented: (a) providing excellent medical assistance, (b) coordinating educational activities to disseminate expertise and establish a professional network, and (c) fostering research to promote scientific knowledge. We presented the number and outcomes of small children KT as a result of this strategy. RESULTS: Three hundred forty-six pediatric KTs were performed in the specialized center from 2009 to 2017, being 130 in children ≤15 kg (38%, being 41 children ≤10 kg) and 216 in >15 kg (62%). Patient survival after 1 and 5 years of the transplant was 97% and 95% in the "small children" group, whereas, in the "heavier children" group, it was 99% and 96% (P = 0.923). Regarding graft survival, we observed in the "small children" group, 91% and 87%, whereas in the "heavier children" group, 94% and 87% (P = 0.873). These results are comparable to the literature data. Groups were similar in the incidence of reoperation, vascular thrombosis, posttransplant lymphoproliferative disease, and estimated glomerular filtration rate. CONCLUSIONS: The strategy allowed an improvement in the number of KT in small children with excellent results. We believe this experience may be useful in other locations.

RESUMO

Wound healing is affected by several factors. Preexisting diagnoses may significantly alter, delay, or inhibit normal wound healing. This is most commonly seen with chronic disorders, such as diabetes and renal failure, but also occurs secondary to aging and substance abuse. Less commonly, genetic or inflammatory disorders are the cause of delayed wound healing. In some cases, it is not the illness, but the treatment that can inhibit wound healing. This is seen in patients getting chemotherapy, radiation, steroids, methotrexate, and a host of other medications. Understanding these processes may help treat or avoid wound healing problems.

RESUMO

BACKGROUND: Muscle weakness, incorrect body water distribution and reduced exercise tolerance are the main characteristics found in renal transplant recipients after surgical treatment. Regular physical supervised exercise programs, at moderate intensity, have been promoted to contrast these aspects, while few data are available for long-term unsupervised mixed exercise plans. Bioelectrical impedance vector analysis (BIVA) provides a semi-quantitative evaluation of body cell mass and body water. This study aims to approach the role of the BIVA analysis in the follow-up of Renal Transplant Group (RTG) and analyze the impact of unsupervised exercise program. METHODS: Thirteen male RTG and ten healthy subjects, adherent to a tailored exercise program, at moderate intensity and prescribed in an unsupervised way, have been followed up for one year. Every six months all the subjects have been submitted to the ergometric test, echocardiographic exam and an analysis of body composition by bioimpedance. They were compared to a healthy control group (HG). RESULTS: A significant reduction of the BMI was observed at the end of the study in the RTG group (T0 24.8±3.2, T12 24.2±3.2 kg/m2; P<0.05). BIVA has shown a lower right quadrant for RTG. All echocardiographic parameters were in a normal range, and no differences were found over time. CONCLUSIONS: Unsupervised tailored and mixed exercise intervention reduces some cardiovascular risks factors. However, it does not modify the frailty of RTG. BIVA analysis seems to have appropriate sensitivity to highlight this aspect.

RESUMO

There is no effectual pathological factor to predict the long-term renal prognosis of IgA nephropathy. Glomerular hypertrophy plays a crucial role in kidney disease outcomes in both experimental models and humans. This study aimed to 1) confirm the long-term prognostic significance of a maximal glomerular diameter (Max GD) ≥ 242.3 µm, 2) test a renal prognosis prediction model adding Max GD ≥ 242.3 µm to the Oxford classification (MEST-C), and 3) examine the time series changes in the long-term renal prognosis of patients with IgA nephropathy. The study included 43 patients diagnosed with IgA nephropathy from 1993 to 1998 at Kameda General Hospital. Renal prognosis with the endpoint of a 50% reduction in estimated glomerular filtration rate (eGFR) or the development of end-stage renal disease requiring dialysis was examined using logistic regression analysis, Cox regression analysis, and the Kaplan-Meier method. Pathological evaluation was performed using MEST-C and Max GD, and the validity of the prediction model was evaluated. Patients with Max GD ≥ 242.3 µm had significantly poor renal prognosis with multivariate Cox analysis (P = 0.0293). The results of the Kaplan-Meier analysis showed that kidney survival rates in the high-Max GD group were significantly lower than those in the low-Max GD group (log rank, P = 0.0043), which was confirmed in propensity score-matched models (log rank, P = 0.0426). Adding Max GD ≥ 242.3 µm to MEST-C improved diagnostic power of the renal prognosis prediction model by renal pathology tissue examination (R2: 3.3 to 14.5%, AICc: 71.8 to 68.0, C statistic: 0.657 to 0.772). We confirm that glomerular hypertrophy is useful as a long-term renal prognostic factor.

RESUMO

OBJECTIVE: To examine the relative risk of end-stage renal disease (ESRD) requiring dialysis among treated ankylosing spondylitis (AS) patients compared with non-AS individuals. METHODS: We used claims data from Taiwan's National Health Insurance Research Database obtained between 2003 and 2012, and enrolled 37,070 newly treated AS patients and randomly selected 370,700 non-AS individuals matched (1:10) for age, sex and year of index date. Those with a history of chronic renal failure or dialysis were excluded. After adjusting for age, sex, diabetes mellitus, hypertension, IgA nephropathy, frequency of serum creatinine examinations, use of methotrexate, sulfasalazine, ciclosporis, corticosteroid, aminoglycoside, amphotericin B, cisplatin, contrast agents and annual cumulative defined daily dose (cDDD) of traditional NSAIDs, selective cyclooxygenase-2 inhibitors (COX-2i) and preferential COX-2i, we calculated the adjusted hazard ratios (aHRs) with 95% confidence intervals using the Cox proportional hazard model to quantify the risk of ESRD in AS patients. We re-selected 6621 AS patients and 6621 non-AS subjects by further matching (1:1) for cDDDs of three groups of NSAIDs to re-estimate the aHRs for ESRD. RESULTS: Fifty-one (0.14%) of the 37,070 AS patients and 1417 (0.38%) of the non-AS individuals developed ESRD after a follow-up of 158,846 and 1,707,757 person-years, respectively. The aHR for ESRD was 0.59 (0.42-0.81) in AS patients compared with non-AS individuals. However, after further matching for cDDD of NSAIDs, the aHR of ESRD was 1.02 (0.41-2.53). Significant risk factors included hypertension, IgA nephropathy and use of COX-2i. CONCLUSIONS: The risk of ESRD was not significantly different between treated AS patients and non-AS individuals matched for age, sex, year of index date and dose of NSAID.

RESUMO

BACKGROUND: Nephronophthisis (NPHP) is a rare autosomal recessive inherited disorder with high heterogeneity. The majority of NPHP patients progress to end-stage renal disease (ESRD) within the first three decades of life. As an inherited disorder with highly genetic heterogeneity and clinical presentations, NPHP still poses a challenging task for nephrologists without special training to make a well-judged decision on its precise diagnosis, let alone its mechanism and optimal therapy. CASE PRESENTATION: A Chinese family with NPHP was recruited in current study. The clinical characteristics (including findings from renal biopsy) of NPHP patients were collected from medical records and the potential responsible genes were explored by the whole exome sequencing (WES). A homozygous deletion of NPHP1 (1-20 exons) was found in both affected patients, which was further confirmed by quantitative PCR. CONCLUSIONS: Homozygous full gene deletion of the NPHP1 gene was identified in a Chinese family with NPHP, which was the molecular pathogenic basis of this disorder. Furthermore, identification of the pathogenic genes for those affected patients can help to have a full knowledge on NPHP's molecular mechanism and precise treatment.

RESUMO

The use of high dialysate bicarbonate for hemodialysis in end-stage renal disease is associated with increased mortality, but potential physiological mediators are poorly understood. Alkalinization due to high dialysate bicarbonate may stimulate organic acid generation, which could lead to poor outcomes. Using measurements of ß-hydroxybutyrate (BHB) and lactate, we quantified organic anion (OA) balance in two single-arm studies comparing high and low bicarbonate prescriptions. In study 1 (n = 10), patients became alkalemic using 37 meq/L dialysate bicarbonate; in contrast, with the use of 27 meq/L dialysate, net bicarbonate loss occurred and blood bicarbonate decreased. Total OA losses were not higher with 37 meq/L dialysate bicarbonate (50.9 vs. 49.1 meq using 27 meq/L, P = 0.66); serum BHB increased in both treatments similarly (P = 0.27); and blood lactate was only slightly higher with the use of 37 meq/L dialysate (P = 0.048), differing by 0.2 meq/L at the end of hemodialysis. In study 2 (n = 7), patients achieved steady state on two bicarbonate prescriptions: they were significantly more acidemic when dialyzed against a 30 meq/L bicarbonate dialysate compared with 35 meq/L and, as in study 1, became alkalemic when dialyzed against the higher bicarbonate dialysate. OA losses were similar to those in study 1 and again did not differ between treatments (38.9 vs. 43.5 meq, P = 0.42). Finally, free fatty acid levels increased throughout hemodialysis and correlated with the change in serum BHB (r = 0.81, P < 0.001), implicating upregulation of lipolysis as the mechanism for increased ketone production. In conclusion, lowering dialysate bicarbonate does not meaningfully reduce organic acid generation during hemodialysis or modify organic anion losses into dialysate.

RESUMO

In recent years, there has been a progressive increase in the number of patients with chronic kidney disease (CKD), whose mortality risk is significantly higher than in general patients, which is associated with cardiovascular risks.In patients with CKD stage 5D before the start of replacement renal therapy for hypertension exceeds 90%. The aim -to analyze the efficacy and safety of the use of melatonin in the complex treatment of arterial hypertension (AH) in patients with CKD of 5 stage with impaired melatonin-forming function of the epiphysis (MFE). 60 people (35 women and 25 men) with a chronic kidney disease of 5 stage, which have violated MFE and AH were examined. For all patients in addition to antihypertensive therapy were prescribed the drug melatonin at a dose of 3 mg, which was taken once a day at 22:00 for 8 weeks. For all examined, before and after the course of treatment, were measured blood pressure (BP), Ambulatory Blood Pressure Monitoring (ABPM) and determination of the concentration of melatonin in the salivaby immunosorbent method. The examined patients showed a high frequency of MFE disturbance both in the daytime and at night - respectively, in 52,4% (p<0,001) and 82,6% (p<0,001). The dynamics of the diurnal BP on the background of treatment was due to changes in the degree of nocturnal decrease of BP, the number of patients in the main group with the "non-dipper" profile, decreased from 44,5% to 27,6% (p<0,05%), the proportion of patients with a daily profile of BP "night-peakear" from 22,4% to 4,8% (p<0,05%). Besides, a statistically significant of the number of persons with a daily profile of BP "dipper" increase in 30,2%. Against the background of complex treatment, there was a decrease in the patient's need for the dose and amount of antihypertensive drugs to achieve BP targets. Our data show a high incidence of MFE disorders in patients with CKD stage VD, and adding to the antihypertensive therapy of the drug melatonin in patients with CKD of 5 stage is effective and safe.

RESUMO

AIMS AND OBJECTIVES: To explore the experience of multiple concurrent symptoms over time and their impact on daily living in patients with end-stage renal disease undergoing dialysis. BACKGROUND: Patients undergoing dialysis experienced multiple concurrent symptoms because of the disease and treatment. Evidence suggests that these symptoms cluster around and have a significant impact on quality of life. However, the experience of this impact remained not clear. DESIGN: A longitudinal descriptive qualitative study. METHODS: Ten patients were purposely selected from the cohort of a longitudinal quantitative study in Hong Kong. A total of 28 face-to-face semi-structured interviews were conducted between July 2017 and July 2018. Interviews were audiotaped, transcribed and analysed using a thematic analysis approach. Findings were reported following the COREQ checklist. RESULTS: Four themes emerged from the data. The first theme "complex symptom experience" described a dynamic pattern of symptoms among patients. Although patients were unaware of the relationships among symptoms, a cluster of tiredness, breathlessness, dizziness and sleep disturbance was identified in the narratives of individual symptoms. The report of symptom experience and its change revealed a unique pattern of symptom perception. The three other themes illustrated the impact of multiple concurrent symptoms on daily living, namely "decreased physical functioning," "changes in social functioning" and "diet and fluid restrictions." CONCLUSIONS: Patients perceived dynamic and complex symptom experiences. This perception appears to be modulated by a number of factors. In addition, these experiences had negative and positive effects on patients' daily living. RELEVANCE TO CLINICAL PRACTICE: Patients perceived unique impact of symptoms on daily living. Therefore, a nurse-led person-centred approach of care is warranted. In addition to routine symptom assessment, nurses need to capture the specific impact of symptoms on day-to-day life. Based on this assessment, symptom management interventions (e.g. health education, referral) can be tailor-made and prioritised.

RESUMO

End-stage kidney disease (ESKD) and heart failure (HF) often coexist and must be managed simultaneously. Multidisciplinary collaboration between nephrology and cardiology is critical when treating patients with such complicated physiology. There is no "one-size-fits-all" approach to the evaluation of patients with new left ventricular systolic dysfunction, and diagnostic testing should be adapted to an individual's risk factors. Guideline-directed medical therapy (GDMT) for systolic heart failure should be employed in these patients. While limited randomized data exist, observational data and post hoc analyses suggest that GDMT, including renin angiotensin aldosterone system inhibitors, is associated with improved cardiovascular outcomes and can be safely initiated at low doses with close monitoring of kidney function in this population. Volume status is typically managed through ultrafiltration, so close communication between cardiology and nephrology is necessary to achieve a patient's optimal dry weight and mitigate intradialytic hypotension. Patient education and engagement regarding sodium and fluid restriction is crucial, and symptom burden should be reassessed following changes to the dialysis regimen.

RESUMO

OBJECTIVE: To explore the potential mechanism of KMUP-1 in the vascular calcification of chronic renal failure (CRF) through mediating NO/cGMP/PKG pathway, and provide novel insights into the CRF treatment. METHODS: CRF rats were treated by KMUP-1 with/without L-NNA (a NOS inhibitor) and then performed by ELISA, alizarin red staining, Von Kossa staining, Masson's trichrome, Sirius red staining and CD3 immunohistochemical staining. Simultaneously, vascular smooth muscle cells (VSMCs) were collected from rats to confirm the effect of KMUP-1 on vascular calcification in vitro via NO/cGMP/PKG pathway. Besides, protein and mRNA expressions were determined via Western blotting and qRT-PCR, respectively. RESULTS: CRF rats were elevated in 24-h urine protein, blood urea nitrogen (BUN), serum creatinine, Cys-C levels and inflammatory cytokines. Besides, CRF rats also showed increased calcium content and ALP level with up-regulated mRNA of osteogenic differentiation-related markers. Furthermore, the up-regulated expressions of eNOS and PKG, as well as down-regulated levels of NOx and cGMP were also found in CRF rats. However, renal failure and vascular calcification of CRF were improved significantly by KMUP-1 treatment via activation of NO/cGMP/PKG pathway. Moreover, KMUP-1 treatment attenuated calcified VSMCs, accompanied by the decreases in the calcified nodules, level of calcium and activity of ALP. In addition, either L-NNA treatment for CRF rats or the calcified VSMCs could antagonize the improving effect of KMUP-1. CONCLUSION: KMUP-1 can improve the renal function and vascular calcification in CRF rats at least in part by activating NO/cGMP/PKG pathway.

RESUMO

Introduction: Sirtuin1 (SIRT1) acts as an anti-aging protein due to anti-apoptotic, anti-oxidative and anti-inflammatory effect and is implicated in several diseases including diabetes or cardiovascular problems. SIRT1 renal overexpression indicates oxidative stress. Similarly, αKlotho was primarily exposed as anti-aging factor. It is primary produced in kidney. It's deficiency is associated with progression of chronic kidney disease and heart disorders. Purpose: The aim of the study was to assess the serum concentration of sirtuin1 and αKlotho in hemodialysis (HD) patients compared to healthy volunteers in regard to age, blood pressure control, residual kidney function (RKF), diabetes, cardiovascular disease, dialysis vintage and type of dialyzer. Patients and Methods: The serum level of SIRT1 and αKlotho was evaluated using ELISA tests in 103 HD patients, median age 67 years and in 21 volunteers. Blood pressure, RRF, echocardiography and dialysis parameters were assessed. HD group was divided according to the presence/absence of RKF. Results: The serum SIRT1 level was higher (28.4 vs 2.71ng/mL, p<0.0001) and αKlotho was lower (433.9 vs 756.6pg/mL, p<0.0001) in HD then in control group. αKlotho was lower in those without RKF (387.2 vs 486.2pg/mL, p=0.028). SIRT1 positively correlated with hemodialysis vintage. αKlotho negatively correlated with left ventricular posterior wall thickness. There was no significant relationship between SIRT1 and αKlotho level and age, blood pressure control, type of dialyzer, Kt/V and diabetes. Multivariate analysis revealed association of SIRT1 with ejection fraction (B -0.72; p=0.32). Conclusion: Elevated SIRT1 and lower αKlotho concentration are associated with impaired kidney function. The decrease in levels of αKlotho may also indicate heart hypertrophy in hemodialysis patients. The role of anti-aging proteins, particularly SIRT1 as biomarkers/predictors of oxidative stress, inflammation and cardiovascular diseases need further examination.

RESUMO

When initiating hemodialysis, incremental hemodialysis takes into account the residual kidney function (RKF) and adds a dialysis regimen to achieve a satisfactory clearance and ultrafiltration. This approach allows less frequent or shorter dialysis sessions than the standard of 3 sessions per week regimen. It is associated with multiple benefits for the patient. However, RKF has to be monitored regularly to enable the dialysis regimen to be adapted accordingly in order to avoid under-dialysis.

RESUMO

Increased arterial stiffness is strongly associated with cardiovascular morbidity and mortality in dialysis patients. Ischemia-modified albumin (IMA) is a useful biomarker of cardiac ischemia. This study was aimed to explore the association between IMA and arterial stiffness in hemodialysis patients. An observational study was conducted with 120 hemodialysis patients. Clinical data and laboratory characteristics were collected. Arterial stiffness was evaluated by brachial-ankle pulse wave velocity (baPWV). Hemodialysis patients had extensive arterial stiffness and high levels of IMA. Comparing to hemodialysis patients with normal baPWV, those with high baPWV had significantly higher levels of IMA (93.7 ± 8.6 versus 73.1 ± 10.7 Ku/L, P = 0.027). The multiple linear regression analysis showed that IMA was significantly associated with arterial stiffness in hemodialysis patients (ß = 0.43, P < 0.001). Moreover, IMA, with a threshold value of 90.4 Ku/L, provided 77.4% sensitivity and 86.6% specificity for predicting arterial stiffness. Hemodialysis patients with arterial stiffness had high levels of IMA. IMA was a good predictive marker of arterial stiffness for hemodialysis patients.

RESUMO

The presence of proteinuria, i.e. an abnormal amount of proteins in the urine is a well documented cardiovascular (CV) and renal risk factor either in the general population or in high-risk populations such as patients with type 2 diabetes, previous CV disease and patients under regular nephrology care. Indeed, the increase in proteinuria levels, even if of small entity, is associated to a faster decline in renal function over time, increased risk of End-Stage-Kidney-Disease and CV mortality. The deleterious effect of proteinuria on the kidney is attributable to the primitive glomerular damage as well as to the direct toxicity the proteinuria exerts on the tubule-interstitium. In addition, the more general association with the increased CV risk can be explained by the evidence that proteinuria can be considered a marker of systemic and renal endothelial damage. A reduction in proteinuria over time (a 30% decrease after 6 months of treatment in proteinuria is considered acceptable) as response to antihypertensive or antiproteinuric drugs protects against the development of all mentioned endpoints. Further studies are needed to better clarify: what is the normal value of proteinuria excretion, how many measures should be done during follow-up to truely assess the risk of future outcomes, what is the exact prognostic role of proteinuria.

RESUMO

Acute kidney injury (AKI), once viewed predominantly as a self-limited and reversible condition, is now recognized as a growing problem associated with significant risks of adverse long-term health outcomes. Many cohort studies have established important relationships between AKI and subsequent risks of recurrent AKI, hospital re-admission, morbidity and mortality from cardiovascular disease and cancer, as well as the development of chronic kidney disease and end-stage kidney disease. In both high-income countries (HICs) and low-income or middle-income countries (LMICs), several challenges exist in providing high-quality, patient-centered care following AKI. Despite advances in our understanding about the long-term risks following AKI, large gaps in knowledge remain about effective interventions that can improve the outcomes of patients. Therapies for high blood pressure, glycaemic control (for patients with diabetes), renin-angiotensin inhibition and statins might be important in improving long-term cardiovascular and kidney outcomes after AKI. Novel strategies that incorporate risk stratification approaches, educational interventions and new models of ambulatory care following AKI have been described, and some of these are now being implemented and evaluated in clinical studies in HICs. Care for AKI in LMICs must overcome additional barriers due to limited resources for diagnosis and management.

RESUMO

BACKGROUND: End-stage renal disease patients living with a kidney transplant (KT) often present with frailty, functional disability, and mobility impairments that may result in a high risk of falls. Postural balance and muscle strength are implicated in the etiology of falls in the geriatric population, and both may be impaired in KT patients. RESEARCH QUESTION: We conducted a cross-sectional investigation to estimate the prevalence of falls, as well as to explore the association between postural balance, muscle strength and history of falls in end-stage renal disease patients living with a KT. METHODS: Fifty-nine prevalent KT patients (age = 53.2 ±â€¯11 years) were enrolled in this cross-sectional study. Participants were classified as fallers/non-fallers and underwent an objectively-measured assessment of postural balance on a stabilometric platform in eyes open (EO), eyes closed (EC), and dual-task (DT) conditions. Center of pressure (CoP) variables were taken for the analysis. In addition, participants underwent isometric (IM) and isokinetic (IK) assessments of lower limb muscle strength on a multi-joint evaluation system. RESULTS: Thirty-four percent of the study participants reported at least one fall in the previous 12 months. In logistic regression analysis, CoP velocity in EO (OR: 1.23, 95 % CI: 1.06-1.43, p = .007), and IK ankle dorsiflexion strength (OR: 0.87, 95 % CI: 0.77-0.99, p = .034) were independently associated with increased odds of falling. SIGNIFICANCE: This cross-sectional study indicates that patients living with a KT presented with a prevalence of falls indicative of a high risk of falling. Postural balance and muscle strength are exercise-modifiable factors and further research is warranted to establish to what extent these measures may be implicated in the etiology of falling in this patient group.
