ABSTRACT

ABSTRACT Objective: To investigate the association between neck circumference and anthropometric, clinical, and biochemical parameters in chronic kidney failure patients on hemodialysis. Methods: This is a cross-sectional study with patients with chronic kidney disease undergoing hemodialysis in Western Bahia. For the data collection, anthropometric measures were taken and clinical and biochemical data were gathered from the patient records and employing a structured questionnaire. A multiple linear regression was applied to evaluate the relationship between neck circumference and the anthropometric, clinical, and biochemical parameters. Results: A total of 119 patients were evaluated, of which 63.03% were men and 57.98% were aged between 35 and 59 years old. The mean neck circumference of the patients was 36.2±3.8 cm. A negative association was found between neck circumference and the female sex (p<0.001), while waist circumference (p<0.001), the body adiposity index (p=0.002), and pre-dialysis serum urea concentration (p=0.006) were positively associated with neck circumference. Conclusion: Neck circumference is inversely associated with the female sex and positively associated with a high waist circumference, body adiposity index, and serum urea concentration in patients with chronic kidney disease on hemodialysis.

ABSTRACT

Introdução: A avaliação do sintoma de fadiga em pessoas com doença renal crônica tem sido um desafio para enfermagem por tratar-se de um sintoma subjetivo e associado a outras comorbidades. Objetivo: Conhecer as estratégias de avaliação do sintoma de fadiga em pessoas com doença renal crônica. Método: Estudo de revisão sistemática da literatura, realizada em três bases de dados (PubMed/MEDLINE, BIREME e LILACS), utilizando os descritores "Renal Insufficiency, Chronic", "Fatigue" e foram verificados os níveis de evidência dos estudos. Para análise dos dados utilizou-se um instrumento de avaliação dos itens e análise descritiva. Resultados: Atenderam aos critérios de inclusão 36 estudos que avaliaram a prevalência de fadiga em 7.587 pessoas com doença renal crônica em 15 países, em quatro continentes; os fatores preditivos foram as características individuais, psicossociais, clínicas e comorbidades; as estratégias de avaliação incluíram 40 instrumentos, informações sociodemograficas e clínicas. Quanto ao nível de evidência, os estudos se concentram nos níveis três e quatro. Considerações finais: A prevalência e os fatores preditivos podem ser manejados com o uso de estratégias de avaliação, válidas para avaliar o sintoma de fadiga em pessoas com doença renal crônica, bem como, com intervenções confiáveis, como a suplementação nutricional, hipnose, acupuntura, ergometria de pernas intradialíticas e apoio social, os quais podem ser adotados pela enfermagem em unidades de nefrologia para promoverem a redução da prevalência do sintoma de fadiga.


Background: The evaluation of fatigue symptom in people with chronic kidney disease has been a challenge for nursing because it is a subjective symptom and associated with other comorbidities. Aim: To analyze the scientific evidence on the prevalence, predictive factors and strategies for the assessment of fatigue symptoms in people with chronic kidney disease. Method: Systematic literature review study conducted in three databases (PubMed / MEDLINE, BIREME and LILACS) using the descriptors "Renal Insufficiency, Chronic", "Fatigue" and the levels of evidence of the studies were verified. For data analysis we used an item evaluation instrument and descriptive analysis. Results: Inclusion criteria were 36 studies that assessed the prevalence of fatigue in 7,587 people with chronic kidney disease in 15 countries in four-continents; predictive factors were individual, psychosocial, clinical and comorbidities; the evaluation strategies included 40 instruments, sociodemographic and clinical information. As for the level of evidence, studies focus on levels three and four. Final considerations: Prevalence and predictive factors can be managed using valid assessment strategies to assess the symptom of fatigue in people with chronic kidney disease, as well as with reliable interventions such as nutritional supplementation, hypnosis, acupuncture, intradialitic leg ergometry and social support, which can be adopted by nursing in nephrology units to promote a reduction in the prevalence of fatigue symptoms.

ABSTRACT

ABSTRACT Objective To investigate the relationship between calcidiol (25(OH)D3) concentrations and iron parameters in patients with chronic kidney disease. Methods This is a cross-sectional, descriptive, and quantitative study. The sample consisted of 86 adult patients of both sexes undergoing dialysis. 25(OH)D3 concentrations were determined by chemiluminescence; food consumption was assessed using 24-hour recalls, and the serum levels of hemoglobin, iron, ferritin, and transferrin saturation were assessed. Data analysis was performed using the program Stata, with a significance level of p<0.05. Results The results pointed to 25(OH)D3 concentrations compatible with sufficiency, iron levels consistent with normality, and ferritin and transferrin saturation above the reference values. The consumption of carbohydrates and lipids was higher in females. There was no relationship between the adequacy of 25(OH)D3 and the presence of anemia and iron parameters. Conclusion Considering that the mean serum levels of iron and 25(OH)D3 were adequate, it is suggested that resistance to erythropoietin and the inflammatory process may have contributed to the percentage of anemic individuals found in the study.


RESUMO Objetivo Investigar a relação entre as concentrações de calcidiol (25(OH)D3) e os parâmetros de ferro em pacientes com doença renal crônica. Métodos É um estudo transversal, descritivo e quantitativo. A amostra foi composta por 86 pacientes, adultos, de ambos os sexos, em terapia dialítica. As concentrações de 25(OH)D3 foram determinadas pelo método de quimioluminescência; o consumo alimentar foi avaliado pela aplicação de Recordatórios de 24 horas e foram avaliados os níveis séricos de hemoglobina, ferro, ferritina e saturação de transferrina. A análise dos dados foi realizada no programa Stata, com nível de significância p<0.05. Resultados Os resultados apontaram para concentrações de 25(OH)D3 compatíveis com suficiência, níveis de ferro compatíveis com a normalidade e ferritina e saturação de transferrina superiores à referência. O consumo de carboidratos e lipídios foi superior no sexo feminino. Não foi verificada relação entre a adequação de 25(OH)D3 e a presença de anemia e parâmetros de ferro. Conclusão Tendo em vista que os níveis médios séricos de ferro e 25(OH)D3 estavam adequados, sugere-se que a resistência à eritropoietina e o processo inflamatório podem ter contribuído para o percentual de anêmicos constatado no estudo.

ABSTRACT

Abstract Introduction: Chronic kidney disease (CKD) is a worldwide public health problem associated with an increased risk of death from cardiovascular complications. Although previous studies have described significant improvements in exercise in functional capacity and quality of life in patients with end-stage kidney disease (ESKD), there is a lack of studies that propose to assess its impact on cardiac function using transthoracic echocardiogram (ECHO). In addition, most of the intradialytic exercise protocols are inconsistent, and incomplete regarding their intensity prescription, time of intervention, and monitoring. Methods: The present study aims to evaluate the effects of an intradialytic cardiovascular rehabilitation protocol (ICRP) using medium intensity aerobic exercises, for 30 min. on cardiac function and functional capacity. In this 6-month longitudinal study, heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure, peripheral oxygen saturation (SpO2) and modified Borg scale will be analyzed in all HD sessions. The cardiac function will be evaluated by left ventricular ejection fraction (LVEF) through ECHO; functional capacity by the six-minute walk test (6MWT); quality of life through the SF-36 questionnaire and routine laboratory tests and KT/Vsp calculation before and after the ICRP. Conclusion: ICRP protocol will be examined and is expected to improve cardiac function, functional capacity, and quality of life in ESKD patients on hemodialysis.

ABSTRACT

A doença renal crônica (DRC) é uma condição clínica de alto risco cardiovascular e os pacientes nos estágios mais avançados da doença que dependem de terapia renal substitutiva frequentemente tem prejuízo cardiorespiratório, níveis elevados de pressão arterial (uso de múltiplas medicações para controle), modulação autonômica prejudicada e graus variados de inflamação. Deste modo este estudo tem como objetivo verificar se o exercício físico aeróbio intradialítico tem impacto em modificar estas alterações. Os pacientes foram selecionados em duas unidades de hemodiálise em São Luís do Maranhão, Brasil, entre junho de 2016 e outubro de 2019, e foram alocados conforme aceitação em grupo controle (GC) e grupo exercício (GE). O GE foi submetido a treinamento aeróbio com bicicleta por um período de 12 semanas. Avaliação física antropométrica, teste de caminhada de 6 minutos (TC6m), ecocardiograma, eletrocardiograma com análise da variabilidade da frequência cardíaca e medidas laboratoriais foram realizadas incluindo interleucina 6 (IL6) antes e após 12 semanas em ambos os grupos. Trinta e um pacientes foram avaliados 15 pacientes no grupo controle (GC) e 16 pacientes no grupo exercício (GE). Após 12 semanas de treinamento houve diminuição da pressão arterial sistólica do grupo exercício em relação ao basal (129,8 ± 9,41mmHg vs 112,00 ± 12,0 mmHg p = 0,03). Não houve alterações na composição corporal e na maioria dos exames laboratoriais, exceto pelo aumento do KTV (índice de adequação de diálise) e diminuição do LDL colesterol no grupo exercício em relação ao grupo controle. No entanto, os níveis de HDL colesterol aumentaram (39,92 ± 6,1 mg/dL vs 48,00 ± 7,85 mg/dL p = 0,02) e IL6 diminuíram (4,56 ± 1,2 pg / mL vs 2,14 ± 1,0 pg / mL p = 0,02). Houve aumento da distância percorrida no teste de caminhada no grupo exercício (473,80 ± 98,6 metros vs 573,50 ± 74,22 metros p = 0,01). Na avaliação ecocardiográfica, verificou-se que no GE houve diminuição da pressão da artéria pulmonar estimada (31,38 ± 2,9 mmhg vs 24,2 ± 1,7 mmhg p = 0,001). Houve melhora na modulação autonômica no GE (RMSSD 11,7 ± 4,2 vs 18,4 ± 5,7 p=0,02), LFnu (52,9 ± 17,2 vs 32,0 ± 18,2 p=0,02) e HFnu (48,1 ± 17,2 vs 68,0 ± 18,2 p=0,01). Não foram evidenciados efeitos adversos e não houve abandono do treinamento. Baseados nestes resultados, é possível concluir que o exercício aeróbio intradialítico por 12 semanas pode melhorar parâmetros cardiorrespiratórios, hemodinâmicos e autonômicos, com boa aderência e sem eventos adversos, podendo ser usado como medida coadjuvante para melhora clínica destes pacientes.


Chronic kidney disease (CKD) is a clinical condition of high cardiovascular risk and patients in the more advanced stages of the disease who depend on renal replacement therapy often experience cardiorespiratory impairment, high blood pressure levels (use of multiple medications for control), modulation impaired autonomy and varying degrees of inflammation. Thus, this study aims to verify whether intradialytic aerobic exercise has an impact on modifying these variables. The patients were selected in two hemodialysis units in São Luís do Maranhão, Brazil, between May 2016 and October 2019, and were allocated according to acceptance in the control group (CG) and exercise group (EG). The group exercise was submitted to aerobic exercise with bicycle for a period of 12 weeks. Anthropometric physical evaluation, 6-minute walk test (6MWT), echocardiogram, electrocardiogram with analysis of heart rate variability (VFC) and laboratory measurements were performed including interleukin 6 (IL6) before and after 12 weeks in both groups. Thirty-one patients were evaluated 15 patients in the control group (CG) and 16 patients in the exercise group (EG). After 12 weeks of training, there was a decrease in systolic blood pressure in the exercise group compared to baseline (129.8 ± 9.41 mmHg vs 112.00 ± 12.0 mmhg p = 0.03). There were no changes in body composition and in most laboratory tests, except for an increase in KTV (dialysis adequacy index) and a decrease in LDL cholesterol in the exercise group compared to the control group. However, HDL cholesterol levels increased (39.92 ± 6.1 mg / dL vs 48.00 ± 7.85 mg / dL p = 0.02) and IL6 decreased (4.56 ± 1.2 pg / mL vs 2.14 ± 1.0 pg / mL p = 0.02). There was an increase in the distance covered in the walking test in the exercise group (473.80 ± 98.6 m vs 573.50 ± 74.22 m p = 0,01). In the echocardiographic evaluation, it was found that in the EG there was a decrease in the estimated pulmonary artery pressure (31.38 ± 2.9 mmhg vs 24.2 ± 1.7 mmhg p = 0.001). There was an improvement in autonomic modulation in the EG (RMSSD 11.7 ± 4.2 vs 18.4 ± 5.7 p = 0.02), LFnu (52.9 ± 17.2 vs 32.0 ± 18.2 p = 0.02) and HFnu (48.1 ± 17.2 vs 68.0 ± 18.2 p = 0.01). There were no adverse effects and training was not abandoned. Based on these results, it is possible to conclude that intradialytic aerobic exercise for 12 weeks can improve cardiorespiratory, hemodynamic, and autonomic parameters, with good adherence and without adverse events, and can be used as a supporting measure for the clinical improvement of these patients.

ABSTRACT

Objective@#This study aimed to examine the association of visit-to-visit variabilities in metabolic factors with chronic kidney disease (CKD) in Shanghai community residents.@*Methods@#We used data from a cohort study of community residents who participated in three examinations in 2008, 2009, and 2013, respectively. Fasting plasma glucose (FPG) level, blood pressure (BP), and lipid levels were determined in 2,109 participants at all three visits, and CKD was evaluated between the second and the third visits. Visit-to-visit variabilities in metabolic factors were described by coefficients of variation (CV) at three visits. A variability score was calculated by adding the numbers of metabolic factors with a high variability defined as the highest quartile of CV. CKD was defined as the estimated glomerular filtration rate < 60 mL/min per 1.73 m @*Results@#A total of 200 (9.5%) participants had CKD at the third visit. Compared with the lowest quartile of CV, the highest quartile was associated with a 70% increased risk of CKD for FPG [odds ratio, @*Conclusion@#The visit-to-visit variabilities in metabolic factors were significantly associated with the risks of CKD in Shanghai community residents.

ABSTRACT

Resumen Introducción: La presión de pulso ampliada (PPA) se asocia a un filtrado glomerular calculado ≤ 60/mL/minuto/1.73 m2, por lo que puede ser útil como prueba diagnóstica para identificar a personas con insuficiencia renal crónica (IRC) estadio K/DOQI III-b. Objetivo: Determinar la utilidad de la PPA como prueba diagnóstica de IRC estadio K/DOQI III-b. Método: Estudio de prueba diagnóstica que incluyó a pacientes adultos sin comorbilidades, registrados en la Cohorte de Trabajadores de la Salud. Se utilizó la fórmula CKD-EPI para calcular la filtración glomerular. Se determinó la presión de pulso restando la presión arterial diastólica a la presión arterial sistólica. Se calculó sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo y prevalencia. Se elaboró una curva ROC para determinar el área bajo la curva. Resultados: Se incluyeron 6215 pacientes. Se observó que una PPA ≥ 50 mm Hg tuvo sensibilidad de 74 %, especificidad de 70 %, valor predictivo positivo de 1 %, valor predictivo negativo de 100 % y prevalencia de 1 %. El punto de inflexión en la curva ROC para identificar IRC K/DOQI III-b fue de 0.71. Conclusión: La PPA ≥ 50 mm Hg es útil como prueba diagnóstica para identificar a personas con IRC estadio K/DOQI III-b.


Abstract Introduction: Increased pulse pressure (IPP) is associated an estimated glomerular filtration ≤ 60/mL/min/1.73 m2; thus, it can be useful as a diagnostic test to identify people with K/DOQI stage III-b chronic kidney disease (CKD). Objective: To determine the usefulness of IPP as a diagnostic test for K/DOQI stage III-b CKD. Method: Diagnostic test study that included adult patients without comorbidities, registered in the Health Workers Cohort. The CKD-EPI formula was used to calculate glomerular filtration. Pulse pressure was determined by subtracting diastolic from systolic blood pressure. Sensitivity, specificity, positive predictive value, negative predictive value and prevalence were calculated using standard formulas. A ROC curve was generated to determine the area under the curve. Results: A total of 6,215 patients were included. An IPP ≥ 50 mmHg was observed to have a sensitivity of 74 %, specificity of 70 %, positive predictive value of 1 %, negative predictive value of 100 % and a prevalence of 1 %. The inflection point in the ROC curve to identify K/DOQI III-b CKD was 0.71. Conclusion: An IPP ≥ 50 mmHg is useful as a diagnostic test to identify people with K/DOQI stage III-b CKD.

ABSTRACT

Resumen: El recién nacido prematuro se enfrenta a las condiciones extrauterinas con sistemas aún inmaduros, tanto anatómica como fisiológicamente. El riñón termina de desarrollarse a finales del tercer trimes tre del embarazo, por lo que está especialmente expuesto a alterar su desarrollo normal en caso de nacer en forma prematura. Esta situación puede condicionar, entre otras consecuencias, una menor masa renal funcional y cambios microvasculares que representan un riesgo elevado de hipertensión arterial y daño renal crónico en el largo plazo. En el presente artículo se analiza la evidencia existente actual sobre estos riesgos en los prematuros y se ofrece un esquema de seguimiento de estos niños desde el punto de vista nefrológico.


Abstract: The premature newborn faces extrauterine conditions with some systems still immature, both ana tomically and physiologically. The kidney finishes developing at the end of the third trimester of pregnancy, so it is especially exposed to alter its normal development if preterm birth occurs. This si tuation may condition, among other consequences, a lower functional renal mass and microvascular changes comprising a high risk of chronic kidney disease in the long term and arterial hypertension. This article analyzes the current evidence on these risks in premature infants and offers a nephrology follow-up scheme of these children.

ABSTRACT

ABSTRACT Background: To analyze the effectiveness and the safety of Sofosbuvir-based regimens to treat patients with chronic hepatitis C virus (HCV) infection and chronic kidney disease (CKD). Methods: A retrospective, observational study in patients with chronic HCV infection and CKD treated with Sofosbuvir-based regimens was performed. Liver fibrosis, comorbidities, HCV genotype and sustained virological resposnse (SVR) at 12th week post-treatment were evaluated. Kidney function was accessed by serum creatinine and glomerular filtration rate (GFR). The assumed level of significance was 5 %. Results: Thirty-five patients were treated. The mean age was 52.1 ± 10.9 years, 19 (54.3 %) were women, 32 (91.4 %) were already kidney transplanted and 3 (8.6 %) were on hemodialysis. The SVR by intention to treat was 88.6 %. The mean GFR was 65.8 ± 28.6 and 63.7 ± 28.3 ml/min pre- and post-treatment respectively (p > 0.05). Treatment was interrupted in 1 (2.85 %) patient due to anemia and in 2 (5.7 %) due to loss of kidney function. Conclusion: Sofosbuvir-based regimens are effective to treat HCV in patients with CKD. In patients with mild CKD this type of therapy seems to be safe.

ABSTRACT

Abstract Aim: To analyze whether the proposed physiotherapy protocol during hemodialysis (HD) increases knee extensor muscle strength, palmar grip strength, respiratory muscle strength, lung function, and functional capacity of individuals with Chronic Renal Insufficiency (CRI) on HD. Methods: A preliminary results study, in which physical therapy intervention was performed in 11 subjects (49.2 ± 8.6 years) with CRI on HD treatment. Initially, Heart Rate Variability (HRV) was collected, with the individual at rest, for 15 minutes, and later, HRV linear and non-linear analyses were performed using HRV Kubios Premium Software. The protocol was performed in the first two hours of the HD session, three times a week for eight weeks, consisting of respiratory exercises, aerobic exercises, and electrical stimulation associated with progressive resistive exercises. The variables evaluated were respiratory muscle strength, knee extensor muscle strength, palmar grip strength, lung function, and functional capacity. Student's t-tests for paired samples and Wilcoxon's tests for non-parametric samples were used considering a significance level of 5%. Results: There was a significant increase in expiratory muscle strength (p = 0,012; Cohen's d = 0,59), knee extensor muscle strength (p = 0,025; Cohen's d = 0,77), palmar grip strength (P = 0,001; Cohen's d = 0,52) and functional capacity (P = 0,009; Cohen's d = 0,83). Conclusion: The proposed protocol is effective in increasing knee extensor muscle strength, palmar grip strength, expiratory muscle strength, and functional capacity of individuals with CRI on HD.

ABSTRACT

SUMMARY Chronic kidney disease is highly prevalent (10-13% of the population), irreversible, progressive, and associated with higher cardiovascular risk. Patients with this pathology remain asymptomatic most of the time, presenting the complications typical of renal dysfunction only in more advanced stages. Its treatment can be conservative (patients without indication for dialysis, usually those with glomerular filtration rate above 15 ml/minute) or replacement therapy (hemodialysis, peritoneal dialysis, and kidney transplantation). The objectives of the conservative treatment for chronic kidney disease are to slow down the progression of kidney dysfunction, treat complications (anemia, bone diseases, cardiovascular diseases), vaccination for hepatitis B, and preparation for kidney replacement therapy.

ABSTRACT

ABSTRACT BACKGROUND: Findings regarding the effects of hyperuricemia on renal function and mortality have been inconsistent. OBJECTIVES: To investigate the effects of hyperuricemia on incident renal replacement therapy and all-cause mortality among patients with chronic kidney disease (CKD). DESIGN AND SETTING: Retrospective cohort study conducted in a medical center in Taiwan. METHODS: Patients with CKD in stages 3-5, without histories of renal replacement therapy, were consecutively recruited from 2007 to 2013. Their medical history, laboratory and medication data were collected from hospital records. The mean uric acid level in the first year of follow-up was used for analyses. Hyperuricemia was defined as mean uric acid level ≥ 7.0 mg/dl in men or ≥ 6.0 mg/dl in women. The primary outcomes were incident renal replacement therapy and all-cause mortality, and these data were retrospectively collected from hospital records until the end of 2015. RESULTS: A total of 4,381 patients were analyzed (mean age 71.0 ± 14.8 years; males 62.7%), and the median follow-up period was 2.5 years. Patients with hyperuricemia were at increased risk of incident renal replacement therapy and all-cause mortality, especially those with CKD in stages 4 or 5. Compared with patients with CKD in stage 3 and normouricemia, patients with CKD in stages 4 or 5 presented significantly higher risk of all-cause mortality only if they had hyperuricemia. CONCLUSIONS: In patients with CKD in stages 3-5, hyperuricemia was associated with higher risk of incident renal replacement therapy and all-cause mortality. Whether treatment with uric acid-lowering drugs in these patients would improve their outcomes merits further investigation.

ABSTRACT

ABSTRACT Introduction: Children with a solitary post-nephrectomy kidney (SNK) are at potential risk of developing kidney disease later in life. In response to the global decline in the number of nephrons, adaptive mechanisms lead to renal injury. The aim of this study was to determine the prevalence and time of onset of high blood pressure (HBP), proteinuria, glomerular filtration rate (GFR) disruption and renal tubular acidosis (RTA) in children with SNK. Materials and methods: After obtaining the approval from our institution's ethics committee, we reviewed the medical records of patients under 18 years of age who underwent unilateral nephrectomy between January 2005 and December 2015 in three university hospitals. Results: We identified 43 patients, 35 (81.4%) cases of unilateral nephrectomy (UNP) were due to a non-oncologic pathology and Wilm's tumor was identified in 8 (18.6%) cases. In patients with non-oncologic disease, 9.3% developed de novo hypertension, with an average time of onset of 7.1 years, 25% developed proteinuria de novo, with an average time of onset of 2.2 years. For GFR, 21.8% presented deterioration of the GFR in an average time of 3.4 years. Ten (43.5%) patients developed some type of de novo renal injury after UNP. Patients with oncologic disease developed the conditions slowly and none of them developed proteinuria. Conclusions: Taking into account the high rate of long term postoperative renal injury, it can be considered that nephrectomy does not prevent this disease. The follow-up of children with SNK requires a multidisciplinary approach and long-term surveillance to detect renal injury.

ABSTRACT

Chronic kidney disease is associated with an increase in cardiovascular risk and mortality, and a decrease in the health-related quality of life. It is known that the physical capacity of patients with chronic kidney disease is lower than their healthy counterparts. It also decreases progressively after the start of hemodialysis, even leading to the loss of functional independence. There is a positive association between exercise and improvement of many targets in chronic kidney disease, especially in dialysis patients, such as cellular apoptosis, immune improvement and inflammation. In addition, several clinical studies and systematic reviews show an improvement in different clinical and laboratory variables and suggest a lower mortality, proving a reduction of health care economic costs. Exercise intervention in dialysis is safe. Although different guidelines promote exercise, it is necessary to work on its implementation on a large scale.

ABSTRACT

ABSTRACT Objectives To compare and assess various outcomes and success of buccal mucosal graft urethroplasty (BMGU) in patients with CKD versus patients having normal renal function. Material and Methods This was a retrospective, single centre study, during period 2013 to 2017. Patients were grouped into two groups. Group 1 had patients with estimated Glomerular Filtration Rate (eGFR)>60mL/min/1.73m2 while group 2 had patients with eGFR <60mL/min/1.73m2. eGFR was calculated according to the MDRD equation. The two groups were compared with regard to various outcomes like length, location of stricture, technique of graft placement, intra-operative blood loss (haemoglobin drop), duration of hospital stay, post-operative complications and recurrence. Results A total of 223 patients were included in study with group 1 had 130 patients and group 2 had 93 patients. Mean age of patients with CKD were higher (47.49 years versus 29.13 years). The mean follow-up period was comparable between both groups (23.29 months and 22.54 months respectively). Patients with CKD had more post-operative Clavien Grade 2 or higher complications (p=0.01) and a greater recurrence rates (p<0.001) than in non-CKD patients. On multivariate analysis, age and CKD status was significant predictor of urethroplasty success (p=0.004) (OR= 14.98 (1.952-114.94, 95% CI). Conclusions CKD patients are more prone to post-operative complications in terms of wound infection, graft uptake and graft failure and higher recurrence rates following BMGU.

ABSTRACT

ABSTRACT Objectives To primarily evaluate the functional outcomes of PCNL for bilateral renal calculi/calculi in solitary functioning kidney with Chronic Kidney Disease(CKD). To identify factors affecting the renal replacement therapy following PCNL. Materials and Methods Patients with bilateral renal calculi/calculi in solitary kidney and CKD (eGFR<60/s.creatinine>2) and Good Performance Status [Eastern Cooperative Oncology Group (ECOG): 0-2] were included in the study. Results A total of 60 patients with CKD who had bilateral renal calculi/calculi in solitary functioning kidney underwent PCNL. At 6 months, eGFR improved or stabilized in 45 (75%) patients, while in 15 (25%) patients eGFR deteriorated. A total of 5 (14.28%) and 2 (25%) patients of CKD stage 4 and 5 respectively had improvement in eGFR as well as CKD stage. Fourteen (82.35%), 21 (60%), 3 (37.5%) patients of CKD stage 3, 4, 5 had improvement in eGFR but not significant enough to cause stage migration. Again 3 (17.65%) , 9 ( 40%) and 3 (37.5%) patients of CKD stage 3, 4, 5 had reduction in eGFR but not significant enough to cause stage migration. None of the patients had worsening of CKD stage. Preoperative CKD stage and eGFR were compared with measurements made at the final follow up visit (6 months). Conclusion Our results indicate that most patients of renal calculi with CKD show improvement or stabilization of renal function with aggressive stone removal. Improvement is more in patients who have mild to moderate CKD. Aggressive management of comorbidities, peri-operative UTI and complications may delay or avoid progression of CKD status in such patients.

ABSTRACT

SUMMARY BACKGROUND: To date, the therapeutic effects of exercise have not yet been evaluated regarding renal function parameters and quality of life specifically in patients with advanced chronic kidney disease. Thus, the study aim was to evaluate the effects of aerobic exercise in renal function and quality of life in patients with advanced chronic kidney disease. METHODS: A quasi-experimental prospective study [NCT03301987] was carried out. Nine patients with advanced chronic kidney disease were recruited from a hospital nephrology unit. Kidney function parameters such as creatinine, creatinine clearance, urea clearance, glomerular filtration rate, and creatinine/weight proportion, as well as the Kidney Disease Quality of Life SF-36 (KDQoL-SF36) were measured at baseline and after 1 month of aerobic exercise. RESULTS: Significant increases (P <.05) were observed for creatinine/weight proportion as well as symptoms, effects, charge, and physical domains of the KDQoL-SF36 after 1 month of therapeutic exercise. The other parameters did not show any statistically significant difference (P >.05). CONCLUSIONS: Aerobic exercise may cause improvements in renal function and quality of life of patients with advanced chronic kidney disease. Further studies about therapeutic exercise protocols specifically in patients with advanced stages of chronic kidney disease should be carried out in order to study their effectiveness and safety.


RESUMO OBJETIVO: Até o momento, os efeitos do exercício terapêutico ainda não tinham sido avaliados quanto aos parâmetros de função renal e qualidade de vida em pacientes com doença renal crônica avançada, especificamente. Assim, o objetivo do estudo foi avaliar os efeitos do exercício aeróbico na função renal e na qualidade de vida em pacientes com doença renal crônica avançada. MÉTODOS: Um estudo prospectivo quase experimental [NCT03301987] foi realizado. Nove pacientes com doença renal crônica avançada foram recrutados de uma unidade de nefrologia hospitalar. Parâmetros de função renal como creatinina, depuração de creatinina, liberação de ureia, taxa de filtração glomerular e creatinina/peso, bem como a qualidade de vida da doença renal SF-36 (KDQoL-SF36) foram medidos no início e após um mês de atividade aeróbica. RESULTADOS: Aumentos significativos (P<0,05) foram mostrados para a proporção de creatinina/peso, bem como sintomas, efeitos, carga e domínios físicos do KDQoL-SF36 após um mês de exercício terapêutico. Os demais parâmetros não apresentaram diferença estatisticamente significante (P>0,05). CONCLUSÕES: O exercício aeróbico pode produzir melhorias na função renal e na qualidade de vida de pacientes com doença renal crônica avançada. Especificamente, novos estudos sobre protocolos de exercícios terapêuticos em pacientes com estágios avançados de doença renal crônica devem ser realizados a fim de estudar sua eficácia e segurança.

ABSTRACT

Abstract Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used medications associated with nephrotoxicity, especially when used chronically. Factors such as advanced age and comorbidities, which in themselves already lead to a decrease in glomerular filtration rate, increase the risk of NSAID-related nephrotoxicity. The main mechanism of NSAID action is cyclooxygenase (COX) enzyme inhibition, interfering on arachidonic acid conversion into E2 prostaglandins E2, prostacyclins and thromboxanes. Within the kidneys, prostaglandins act as vasodilators, increasing renal perfusion. This vasodilatation is a counter regulation of mechanisms, such as the renin-angiotensin-aldosterone system works and that of the sympathetic nervous system, culminating with compensation to ensure adequate flow to the organ. NSAIDs inhibit this mechanism and can lead to acute kidney injury (AKI). High doses of NSAIDs have been implicated as causes of AKI, especially in the elderly. The main form of AKI by NSAIDs is hemodynamically mediated. The second form of NSAID-induced AKI is acute interstitial nephritis, which may manifest as nephrotic proteinuria. Long-term NSAID use can lead to chronic kidney disease (CKD). In patients without renal diseases, young and without comorbidities, NSAIDs are not greatly harmful. However, because of its dose-dependent effect, caution should be exercised in chronic use, since it increases the risk of developing nephrotoxicity.


Resumo Os anti-inflamatórios não esteroidais (AINEs) são medicamentos comumente utilizados, associados à nefrotoxicidade, sobretudo quando utilizados cronicamente. Fatores como idade avançada e comorbidades, que por si só já levam à diminuição da taxa de filtração glomerular, aumentam o risco de nefrotoxicidade dos AINEs. O principal mecanismo de ação dos AINEs é a inibição da enzima ciclooxigenase (COX), interferindo na conversão do ácido araquidônico em prostaglandinas E2, prostaciclinas e tromboxanos. Nos rins, as prostaglandinas atuam como vasodilatadoras, aumentando a perfusão renal. Essa vasodilatação atua como uma contrarregulação de mecanismos, como a atuação do sistema renina-angiotensina-aldosterona e do sistema nervoso simpático, culminando com uma compensação para assegurar o fluxo adequado ao órgão. O uso de AINEs inibe esse mecanismo, podendo causar lesão renal aguda (LRA). Altas doses de AINEs têm sido implicadas como causas de LRA, especialmente em idosos. A principal forma de LRA por AINEs é a hemodinamicamente mediada. A segunda forma de apresentação da LRA induzida por AINES é a nefrite intersticial aguda, que pode se manifestar com proteinúria nefrótica. O uso de AINEs em longo prazo pode ocasionar doença renal crônica (DRC). Nos pacientes sem doenças renais, jovens e sem comorbidades, os AINEs não apresentam grandes malefícios. Entretanto, por seu efeito dose-dependente, deve-se ter grande cautela no uso crônico, por aumentar risco de desenvolver nefrotoxicidade.
