ABSTRACT

Introducción: la amiloidosis AA puede ser una complicación de ciertos trastornos inflamatorios crónicos, aunque entre el 21% y 50% puede ser idiopática. No existe un tratamiento específico. El tocilizumab, dirigido contra el receptor de IL-6 y orientado a disminuir la producción de SAA, podría ser eficaz. Métodos: en este estudio informamos datos de 6 pacientes con amiloidosis AA tratados con tocilizumab monoterapia subcutáneo en el período 2011-2018. Los criterios de valoración principales fueron la mejora clínica y bioquímica de los órganos afectados y los parámetros bioquímicos marcadores de inflamación. Resultados: el riñón estaba afectado en todos los pacientes, manifestándose con caída del filtrado glomerular y síndrome nefrótico. La hemorragia digestiva se presentó en un paciente y otro tenía afectación pulmonar en la biopsia. Luego del posterior al tratamiento, todos mejoraron el hematocrito, la albúmina sérica y el índice de masa corporal. El SAA disminuyó en 5 pacientes. Un paciente mejoró su función renal, mientras 4 se mantuvieron estables. Tres pacientes disminuyeron los valores de proteinuria. Conclusión: el tratamiento con tocilizumab podría ser eficaz en el tratamiento de los pacientes con amiloidosis AA. (AU)


Introduction: AA amyloidosis can be a complication of certain chronic inflammatory disorders, although between 21% and 50% can be idiopathic. There is no specific treatment. Tocilizumab, directed against the IL-6 receptor and aimed at decreasing SAA production, could be effective. Methods: in this study, we report data from 6 patients with AA amyloidosis treated with subcutaneous tocilizumab monotherapy between the period 2011-2018. The main endpoints were the clinical and biochemical improvement of the affected organs and the biochemical parameters markers of inflammation. Results: the kidney was affected in all patients, manifesting with a fall in glomerular filtration rate and nephrotic syndrome. Gastrointestinal bleeding occurred in one patient and another had lung involvement on biopsy. After treatment, all improved hematocrit, serum albumin, and body mass index. SAA decreased in 5 patients. One patient improved his kidney function, while 4 remained stable. Three patients decreased proteinuria values. Conclusion: treatment with tocilizumab could be effective in the treatment of patients with AA amyloidosis. (AU)

ABSTRACT

ABSTRACT Introduction Mutations affecting genes involved in oxidative and signaling pathways may be associated with kidney disease in sickle cell anemia. We determined the allele and genotype frequencies of some polymorphisms in the promoter regions of the Heme Oxygenase-1 (HMOX1) [rs2071746 (A > T) and (GT)n repeats, short (S) and long (L) alleles] and Bone Morphogenetic Protein Receptor type-1B (BMPR1B) [rs17022863 (A > G), rs4331783 (A > G) and rs1470409 (A > G)] genes in 75 adult patients with sickle cell anemia and 160 healthy controls and investigated whether these polymorphisms may influence the estimated glomerular filtration rate for the patients. Methods The single nucleotide polymorphisms were genotyped using the TaqMan assays, the HMOX1(GT)n repeats were determined by polymerase chain reaction fragment size analysis and the estimated glomerular filtration rate was calculated by the Modification of Diet in Renal Disease formula. Results Regarding the HMOX1rs2071746, the estimated glomerular filtration rate median was significantly higher in TT patients (p = 0.019), including when TT was compared with AT + AA (p = 0.009); for the (GT)n repeats, the estimated glomerular filtration rate medians of SS, SL and LL significantly differed (p = 0.009), being the LL estimated glomerular filtration rate median significantly higher, when compared with the LS + SS (p = 0.005). These results suggest that both the homozygotes, TT for rs2071746 and LL for (GT)n repeats, lead to a higher risk of developing renal complications. Concerning the BMPR1B, the frequencies of GG for rs17022863 and AA for rs4331783 were significantly higher in patients than in controls (p = 0.002 and p = 0.008, respectively), however no association with estimated glomerular filtration rate was found. Conclusion These results contribute to a better understanding of the genetic factors related to the development of nephropathy in sickle cell anemia patients.

ABSTRACT

Introducción. En pediatría, el filtrado glomerular (FG) se puede calcular con el clearance (depuración) de creatinina medida corregida en ml/min/1,73 m2, o se puede estimar según la fórmula de Schwartz (FGe = talla/creatinina plasmática x k). La constante k depende del método de determinación de creatinina plasmática: k = 0,55 para el método colorimétrico de Jaffe, y k =0,413 para el método enzimático. Nuestro laboratorio utiliza el método colorimétrico cinético compensado (MCCC), se observan discordancias entre el FG estimado y el medido.Hipótesis: Los valores de k propuestos no se ajustan al MCCC de creatinina plasmática. Objetivo. Calcular el valor de k que permita estimar el FG mediante la cuantificación de la creatinina con el MCCC. Métodos. Diseño descriptivo correlacional. Se incluyeron pacientes de entre 3 y 18 años con FG normal o alterado atendidos en el Servicio de Nefrología Infantil entre julio de 2017 y enero de 2018 con control de esfínteres y firma del consentimiento. Se excluyeron pacientes desnutridos y con mielomeningocele. Las variables estudiadas fueron: creatinina plasmática y urinaria, talla y diuresis de 24 horas. Resultados. Se analizaron 184 pacientes, con una edad media de 10 años. La mediana del clearance de creatinina medido corregido fue de 123 ml/min/1,73 m2. La correlación lineal entre la talla y la creatinina plasmática y el clearance de creatinina medido corregido arrojó un valor de k de 0,499 (r = 0,974 y r2 = 0,949). La correlación lineal entre el FG estimado (k = 0,499) y el clearance de creatinina medido corregido mostró un coeficiente b = 0,999 (r = 0,951 y r2= 0,903). Conclusión. Según este estudio, la constante que permite estimar el filtrado glomerular al cuantificar la creatinina plasmática con el método colorimétrico cinético compensado es de 0,499.


Introduction. In pediatrics, glomerular filtration rate (GFR) may be estimated by measured corrected creatinine clearance (mcCrCl) (mL/min/1.73 m2) or the Schwartz formula (eGFR = height/plasma creatinine x k). The constant k depends on the plasma creatinine determination method: k = 0.55 for the Jaffe colorimetric method and k = 0.413 for the enzymatic method. Our laboratory uses the compensated kinetic colorimetric assay (CKC), and differences are observed between the estimated and measured GFR.Hypothesis: The proposed values of k do not adjust to the CKC method for plasma creatinine. Objective. To calculate a k value that allows to estimate GFR through creatinine measurement with CKC. Methods. Correlational, descriptive design. Patients aged 3-18 years seen at the Division of Pediatric Nephrology between July 2017 and January 2018 with normal or altered GFR, bladder and bowel control, and signed consent were included. Malnourished and myelomeningocele patients were excluded. Studied variables were plasma and urine creatinine, height, and 24-hour urine output. Results. A total of 184 patients were analyzed, their mean age was 10 years. Median mcCrCl was 123 mL/min/1.73 m2. The linear correlation between height and plasma creatinine and mcCrCl resulted in a k value of 0.499 (r = 0.974 and r2 = 0.949). The linear correlation between the estimated GFR (k = 0.499) and mcCrCl resulted in a 0.999 ß coefficient (r = 0.951 and r2 = 0.903). Conclusion. According to this study, the constant that allows to estimate GFR when measuring plasma creatinine with the CKC method is 0.499.

ABSTRACT

Introdução: Usuários do sistema de saúde com doenças crônicas não transmissíveis devem estar em acompanhamento constante para evitar complicações em seu estado de saúde. Objetivo: Analisar os indicadores laboratoriais de saúde em usuários de uma Unidade Básica de Saúde com e sem o diagnóstico para a diabetes e hipertensão. Métodos: A amostra foi de 231 usuários de uma unidade básica de saúde da cidade de Santarém-PA, maiores de idade, que foram agrupados em pacientes com DM/HAS (DM/HAS; n=144), e sem o diagnóstico para DM/HAS (AUS; n=87). As coletas envolveram informações socioeconômicas, clínicas e laboratoriais. Os dados foram tratados com estatística descritiva e inferencial, adotando-se p<0.05. Resultados: Tanto no DM/HAS como no AUS predominou o sexo feminino, estado civil casado, com vínculo empregatício, cor de pele parda, com 4-7 anos de estudo, renda de 1-2 salários, não tabagistas, não etilista e faixa etária de 38-77 anos. A HAS foi a doença mais presente de forma geral, bem como por sexo. Identificou-se no DM/HAS valores menores para a taxa de filtração glomerular (TFG) e maiores valores para a glicemia, triglicerídeos, colesterol total, LDL-c e não HDL-c. Conclusão: De acordo com a proposta desenvolvida, destaca-se que os usuários com DM/HAS apresentam associação positiva para valores alterados de glicemia, colesterol total, não HDL-c, triglicerídeos, TFG e para a presença da síndrome metabólica e risco cardiovascular moderado/alto.


Introduction: Users of the health system with chronic non-communicable diseases must be constantly monitored to avoid complications in their health status. Objective: Analyze laboratory health indicators in users of a Basic Health Unit with and without a diagnosis for diabetes and hypertension. Methods: The sample consisted of 231 users of a basic health unit in the city of Santarém-PA, all of them of age, grouped into patients with DM/SAH (DM/SAH; n=144), and without the diagnosis for DM/SAH (ABS; n=87). The collections involved socioeconomic, clinical, and laboratory information. The data were treated with descriptive and inferential statistics, adopting p <0.05. Results: In both DM/SAH and ABS groups, there was a predominance of female individuals, married status, employed, brown skin color, with 4-7 years of study, income of 1-2 salaries, non-smokers, non-alcoholic drinkers, and aged between 38-77 years. SAH was the most common disease in general, as well as when analyzing by gender. Lower values for the glomerular filtration rate (GFR) were identified in the DM/SAH and higher values for the glycemia, triglycerides, total cholesterol, LDL-c, and non-HDL-c. Conclusion: According to the proposal of this paper, it is noteworthy that users with DM/SAH have a positive association for altered values of blood glucose, total cholesterol, non-HDL-c, triglycerides, GFR, and for the presence of metabolic syndrome and moderate/high cardiovascular risk.

ABSTRACT

Abstract Introduction: Postoperative acute kidney injury contributes to longer hospital stays and increased costs related to cardiac surgery in the elderly. We analyse the influence of the patient's age on risk factors for acute kidney injury after cardiac valve surgery. Methods: We evaluated the prevalence and risk factors for acute kidney injury in 939 consecutive patients undergoing valve surgery, between 2013 and 2018. Results: The prevalence of acute kidney injury was 19.5%. Hypertension (P=0.017); RR (95% CI): 1.74 (1.10-3.48), age ≥70 years (P=0.006); RR (95% CI): 1.79 (1.17-2.72), preoperative haematocrit <33% (P=0.009); RR (95% CI): 2.04 (1.19-3.48), glomerular filtration rate <60 ml/min/1.73 m2 (P<0.0001); RR (95%) CI: 2.36 (1.54-3.62) and cardiac catheterization <8 days before surgery (P=0.021); RR (95% CI): 2.15 (1.12-4.11) were identified as independent risk factors. In patients older than 70 years, with no kidney disease diagnosed preoperatively, glomerular filtration rate <70 ml/min/1.73 m2, male gender, cardiopulmonary bypass time, preoperative haematocrit <36% and preoperative therapy with angiotensin-converting enzyme inhibitors were risk factors for acute kidney injury after valve surgery. Conclusions: In elderly patients, postoperative acute kidney injury develops with higher values of preoperative glomerular filtration rate than those observed in a younger population. Preoperative correction of anaemia, discontinuation of angiotensin-converting enzyme inhibitors and surgical techniques reducing cardiopulmonary bypass time would be considered to reduce the prevalence of renal failure.

ABSTRACT

ABSTRACT Purpose: Radical nephrectomy (RN) is the standard surgical type for pathological stage T3a (pT3a) renal cell carcinoma (RCC). Recently, some studies have suggested equivalence between partial nephrectomy (PN) and RN for oncologic control and have shown the benefits of PN for better renal function. We conducted this meta-analysis to assess oncologic outcomes, perioperative outcomes and renal function between two groups among patients with pT3a RCC. Materials and methods: PubMed, Scopus, Web of Science, Science Direct, Ovid MEDLINE, The Cochrane Library, Embase and Google Scholar were searched for eligible articles. The endpoints of the final analysis included overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), surgical complications, operative time, estimated blood loss (EBL), serum creatinine and estimated glomerular filtration rate (eGFR). Results: Twelve studies of moderate to high quality, including 14.152 patients, were examined. PN showed superiority for renal functional preservation, providing higher eGFR (WMD=12.48mL/min; 95%CI: 10.28 to 14.67; P <0.00001) and lower serum creatinine (WMD=-0.31mg/dL; 95%CI: −0.40 to −0.21; P <0.00001). There were no significant differences between PN and RN regarding operative time, EBL, surgical complications, OS, RFS and CSS. Despite inherent selection bias, most pooled estimates were consistent in sensitivity analysis and subgroup analysis. More positive margins were found in the PN group (RR=2.42; 95%CI: 1.25-4.68; P=0.009). Conclusions: PN may be more suitable for treating pT3a RCC than RN because it provides a similar survival time (OS or RFS) and superior renal function. Nevertheless, this result is still disputed, and more high-quality studies are required.

ABSTRACT

ABSTRACT Purpose: Renal artery pseudoaneurysms (RAPs) and arteriovenous fistulas (AVFs) are rare but potentially life-threatening complications after partial nephrectomy (PN). Selective arterial embolization (SAE) is an effective method for controlling RAPs/AVFs. We assessed the clinical factors affecting the occurrence of RAPs/AVFs after PN and the effects of SAE on postsurgical renal function. Materials and Methods: Four hundred ninety-three patients who underwent PN were retrospectively reviewed. They were placed in either the SAE or the non-SAE group. The effects of clinical factors, including R.E.N.A.L. scores, on the occurrence of RAPs/AVFs were analyzed. The influence of SAE on the estimated glomerular filtration rate (eGFR) during the first postoperative year was evaluated. Results: Thirty-three (6.7%) patients experienced RAPs/AVFs within 8 days of the median interval between PN and SAE. The SAE group had significantly higher R.E.N.A.L. scores, higher N component scores, and higher L component scores (all, p <0.05). In the multivariate analysis, higher N component scores were associated with the occurrence of RAPs/AVFs (Odds ratio: 1.96, p=0.039). In the SAE group, the mean 3-day postembolization eGFR was significantly lower than the mean 3-day postoperative eGFR (p <0.01). This difference in the eGFRs was still present 1 year later. Conclusions: Renal tumors located near the renal sinus and collecting system were associated with a higher risk for RAPs/AVFs after PN. Although SAE was an effective method for controlling symptomatic RAPs/AVFs after PN, a procedure-related impairment of renal function after SAE could occur and still be present at the end of the first postoperative year.

ABSTRACT

Resumo O objetivo do presente estudo foi verificar a prevalência de DRC e os fatores a ela associados em adultos jovens (18-59 anos) de Rio Branco, Acre. Trata-se de um inquérito de base populacional realizado em 2014, nas zonas urbana e rural do município de Rio Branco, Acre. A DRC foi definida pela taxa de filtração glomerular (TFG) < 60 ml/min/1,73 m², estimada pela CKD-EPI, e presença de albuminúria > 29 mg/g. Medidas de associação foram estimadas por regressão logística, com grau de confiança de 95%. A prevalência geral de DRC foi de 6,2%. A presença de DRC foi maior entre as mulheres, naqueles com 40 a 59 anos, de cor da pele não-branca, com menor escolaridade e entre os sedentários. Houve diferenças estatisticamente significativas na distribuição segundo a presença de DRC nas variáveis hipertensão arterial, diabetes e internação nos últimos 12 meses. A DRC entre os adultos esteve associada ao sexo feminino (OR: 2,41; IC95%: 1,14-5,12), diabetes (OR: 4,67; IC95%: 1,28-17,03) e hipertensão arterial (OR: 1,98; IC95%: 1,16-3,37). A DRC apresenta alta prevalência e está associada às doenças crônicas, evidenciando a necessidade de medidas em saúde pública para detecção precoce e prevenção da sua progressão.


Abstract The scope of this study was to establish the prevalence of CKD and associated factors among young adults (18-59 years of age) from Rio Branco in the State of Acre. It involved a population-based survey conducted in 2014, in the urban and rural areas of the municipality and CKD was defined as the glomerular filtration rate (GFR) < 60ml/min/1.73m², estimated by the CKD-EPI, and the presence of albuminuria > 29 mg/g. Association measures were estimated by logistic regression, with a confidence level of 95%. The overall prevalence of CKD was 6.2%. The presence of CKD was higher among women, aged 40 to 59 years, with non-white skin color, with lower schooling, and of sedentary disposition. There were statistically significant differences in the distribution according to the presence of CKD in the hypertension, diabetes and hospitalization variables over the past 12 months. CKD among adults was associated with the female sex (OR: 2.41, 95%CI: 1.14-5.12), diabetes (OR: 4.67, 95%CI: 1.28-17.03) and arterial hypertension (OR: 1.98; 95%CI: 1.16-3.37). CKD reveals a high prevalence and is associated with chronic diseases, calling for the need for public health measures for early detection and prevention of its progression.

ABSTRACT

ABSTRACT Objective To examine the association of between serum fibroblast growth factor 23 and the functional capacity among independent individuals, aged 80 or older. Methods The functional capacity of 144 elderly was assessed by Instrumental Activities of Daily Living, cognitive tests, handgrip strength and the timed ability to rise from a chair and sit down five times. Fibroblast growth factor 23 was measured using an ELISA assay. Results Participants in the lowest fibroblast growth factor 23 tertile had the highest mean±standard deviation estimated glomerular filtration rate, the highest mean hemoglobin level, the lowest average number of diseases and the lowest number of medications used. In participants with the estimated glomerular filtration rate >45mL/minute/1.73m2, mean fibroblast growth factor 23 level was higher in those with 25(OH) vitamin D <20ng/mL than in those with 25(OH) vitamin D ≥20ng/mL (75.6RU/mL±42.8 versus 68.5RU/mL±41.7; p<0.001). There was an increase in the mean serum cystatin C (from 1.3mg/mL±0.3 to 1.5mg/mL±0.3 to 1.7mg/mL±0.4) as function of higher fibroblast growth factor 23 tertile (p<0.001). Fibroblast growth factor 23 levels were not significantly associated with capacity in physical or cognitive tests. Conclusion In independent community-dwelling elderly, aged ≥80 years, fibroblast growth factor 23 was associated with aged-related comorbidities and renal function but not with functional capacity.


RESUMO Objetivo Examinar a associação entre o fator de crescimento de fibroblastos 23 sérico e a capacidade funcional em indivíduos independentes, com 80 anos ou mais. Métodos A capacidade funcional de 144 idosos foi avaliada por meio de Atividades Instrumentais da Vida Diária, testes cognitivos, força de preensão manual e capacidade de levantar de uma cadeira e sentar cinco vezes. O fator de crescimento de fibroblastos 23 foi medido pelo teste ELISA. Resultados Os participantes no tercil mais baixo de fator de crescimento de fibroblastos 23 tiveram a maior média±desvio-padrão da taxa de filtração glomerular estimada, concentração média de hemoglobina mais alta, menor número médio de doenças e menor número de medicamentos utilizados. Em participantes com taxa de filtração glomerular estimada >45mL/minuto/1,73m2, o nível médio do fator de crescimento de fibroblastos 23 foi maior naqueles com 25(OH) vitamina D <20ng/mL do que naqueles com 25(OH) vitamina D ≥20ng/mL (75,6RU/mL±42,8 versus 68,5RU/mL±41,7; p<0,001). Houve aumento na cistatina C sérica média (de 1,3mg/mL±0,3 a 1,5mg/mL±0,3 a 1,7mg/mL±0,4) em função do tercil de fator de crescimento 23 de fibroblastos mais alto (p<0,001). Os níveis de fator de crescimento de fibroblastos 23 não foram significativamente associados à capacidade em testes físicos ou cognitivos. Conclusão Em idosos independentes residentes na comunidade ≥80 anos, o fator de crescimento de fibroblastos 23 foi associado a comorbidades relacionadas à idade e à função renal, mas não à capacidade funcional.

ABSTRACT

Chronic kidney disease (CKD) is one of the main chronic diseases affecting the world population due to its high prevalence and increasing morbidity. Similarly, obesity gained the interest of the scientific community as it directly or indirectly increases mortality from cardiovascular causes, and its prevalence characterizes a pandemic. The objective of this study was to investigate obesity measured by body mass index as a predictor for end-stage renal disease in the general adult population. A systematic review and meta-analysis was carried out by searching 10 databases for prospective or retrospective cohort studies, with no restrictions on the language of publication, including adults with obesity without previous renal disease and who evolved to CKD (diagnosed by estimated glomerular filtration rate below 60 mL&mac_middot;min-1&mac_middot;(1.73 m2)-1 over the follow-up period. The R software and Meta package were used for data analysis. After removing duplicates, 5431 studies were submitted to the steps of the systematic review, and 21 articles were included in the data analysis. In total, 3,504,303 patients, 521,216 with obesity, and an average follow-up time of 9.86 years were included. The relative risk of obese people for developing CKD in the random effects model was 1.81 (95%CI: 1.52-2.16). The evidence found in this meta-analysis confirmed that obese people are at higher risk of developing CKD that the non-obese population (1.81 times higher), with obesity being a priority risk factor in preventive actions.

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 Introduction: Chronic Kidney Disease is a pathology of great impact on public health worldwide, its progression is determined by limitations in the control of its risk factors and prognosis. Nephroprotection programs monitor, control, and limit the progression of this disease in the patients while trying to lead them to meet the specific program goals. Objective: To determine the factors that boost the progression of Chronic Kidney Disease in patients treated in a nephroprotection program. Materials and methods: This retrospective analytical observational cohort study was carried out in 5872 patients from a nephroprotection program with different stages of Chronic Kidney Disease, in the department of Nariño between 2016 and 2018. The progression of CKD corresponded to a decrease in the Glomerular Filtration Rate by 5mL / min / 1.73 m2 or more; this information was obtained from the program's database. An explanatory model was built and adjusted taking into consideration demographic and clinical variables. According to the design, a binomial model with a logarithmic link function was used to estimate the regression coefficients of the variables of interest. The association measures were the Relative risks. Results: In the final results it was found that 72.2% were women, 75.1% were 60 years old or older, 12.4% were afro-colombian, 85% were mixed race, and 49.2% presented progression (95% CI 47 , 9-50.4) of the cases. The factors that best explained the relationship between CKD progression were: being a man with an adjusted RR of 1.04 (95% CI: 1.00-1.15), and having a CKD stage of 4, 5 and 3a-b, with adjusted RR 1.62 (CI1.36-1.94) and 1.41 (CI1.21-1.63) respectively. Conclusions: In the Nariño population of Colombia that is affiliated to a nephroprotection program the progression of CKD was 49.2% according to the male sex and the advanced stages of the condition.

ABSTRACT

Objetivos: o óleo de peixe, rico em ácido eicosapentaenoico (EPA), mostrou benefícios renoprotetores em modelos animais de doenças crônicas. O objetivo deste trabalho foi avaliar os efeitos da suplementação com óleo de peixe três vezes mais concentrado em EPA (EPA 3X) na função renal de ratos e a eficiência desta suplementação por um curto período de tempo. Metodologia: ratos Wistar (n=16) foram divididos em dois grupos, controle (C) e suplementado (CO) por 14 dias com óleo de peixe (EPA 3X). Foram determinados os seguintes parâmetros: ganho de peso, ingesta de água e ração, fluxo urinário, proteinemia, trigliceridemia, osmolaridade, clearance de creatinina e fração de excreção de sódio. Resultados: os ratos suplementados tiveram níveis de triglicerídeos no plasma 58,4% menores que os ratos controle (p=0,0239), entretanto os restantes dos parâmetros sistêmicos avaliados não apresentaram alterações. A suplementação com óleo de peixe não alterou o fluxo urinário. Entretanto, no grupo CO identificou-se um aumento na filtração glomerular, com um incremento em média de 67,8% no clearance de creatinina em relação ao grupo C (p=0,054). A excreção média de proteínas totais na urina e a fração de excreção de sódio foram semelhantes entre os grupos. Conclusão: a suplementação com óleo de peixe três vezes mais concentrado em EPA por um período curto de tempo (quinze dias) provocou alterações significativas tanto em parâmetros sistêmicos (redução significativa na trigliceridemia) quanto na função renal de ratos controle (incremento na filtração glomerular) indicando a eficiência desta suplementação.


Objective: Fish oil, rich in eicosapentaenoic acid (EPA), has shown renoprotective benefits in animal models of chronic diseases. The objective of this work was to evaluate the effects of supplementation with fish oil three times more concentrated in EPA (EPA 3X) on renal function of rats and the efficiency of this supplementation for a short period of time. Methodology: Wistar rats (n=16) were divided into two groups, control (C) and supplemented (CO), supplemented for 14 days with fish oil (EPA 3X). The following parameters were determined: weight gain, water and feed intake, urinary flow, proteinemia, triglyceridemia, osmolarity, creatinine clearance and fractional sodium excretion. Results: The supplemented rats had plasma triglyceride levels 58.4% lower than control rats (p = 0.0239), however the rest of the evaluated systemic parameters did not change. Fish oil supplementation did not alter urinary flow. However, in the CO group an increase in glomerular filtration was identified, with an increase of 67.8% on average in creatinine clearance compared to group C (p = 0.054. The mean excretion of total proteins in the urine and the fractional sodium excretion were similar between groups. Conclusion: Supplementation with fish oil three times more concentrated in EPA for a short period of time (fifteen days) caused significant changes both in systemic parameters (significant reduction in triglyceridemia) and in the renal function of control rats (increase in glomerular filtration) indicating the efficiency of supplementation.

ABSTRACT

Abstract Introduction: the Colombian guidelines for chronic kidney disease (CKD) recommend estimating glomerular filtration (GF) using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. No studies have been performed in the Colombian population to compare the accuracy of this equation to that of others used in clinical practice. Design and methods: we evaluated the GF estimation performance of the Modification of Diet in Renal Disease (MDRD-4), Cockroft-Gault (CG) and body surface area adjusted Cockroft-Gault (CG-BSA) equations against the CKD-EPI equation in 757 adult patients. Performance was evaluated using bias, precision and accuracy measurements. Results: the mean GF by CKD-EPI was 37.32±12.71 mL/min/1.73m2; by MDRD-4 it was 39.8±13.2 mL/min/1.73m2, by CG it was 35±12.6 mL/min and by CG-BSA it was 34.52±11.34 mL/ min/1.73m2. All the equations had bias with respect to GF by CKD-EPI. The most accurate equation was GF estimated by MDRD-4 (MeGF) with 97.1 and 99.74% of measurements within 15 and 30%, respectively; and the least accurate was GF estimated by CG (CGeGF) with 59.7 and 81.77% of the measurements within 15 and 30%, respectively. The concordance correlation coefficient between GF by CKD-EPI and MDRD-4 was 0.97, with CG and CG-BSA at 0.78 and 0.85, respectively Conclusions: the most accurate alternative equation for estimating glomerular filtration in this Colombian population is MDRD-4, which has a high concordance with the CKD-EPI equation. Estimation of GF with the CG equation is not recommended.


Resumen Introducción: las guías colombianas de enfermedad renal crónica (ERC) recomiendan estimar la filtración glomerular (FG) con la fórmula de epidemiología de la enfermedad renal crónica (CKD-EPI). No se han realizado estudios que comparen en la población colombiana la exactitud de esta fórmula con otras utilizadas en la práctica clínica. Diseño y métodos: en 757 pacientes adultos evaluamos el desempeño para estimar la FG por las fórmulas de la modificación de la dieta en la enfermedad renal (MDRD-4), Cockroft-Gault (CG) y Cockroft-Gault corregida para la superficie corporal (CG-SC) comparada con la fórmula de CKD-EPI. El desempeño se evaluó con mediciones del sesgo, precisión y exactitud. Resultados: la media de la FG por CKD-EPI fue 37.32±12.71 mL/min/1.73m2, por MDRD-4 de 39.8±13.2 mL/min/1.73m2, por CG fue 35±12.6 mL/min y por CG-SC de 34.52±11.34 mL/ min/1.73m2. Todas las fórmulas tuvieron un sesgo con relación a la FG por CKD-EPI. La fórmula más exacta fue la FG estimada por MDRD-4 (FGeM) con una proporción de mediciones dentro del 15 y 30% en 97.1 y 99.74% de las mediciones respectivamente, y la menos exacta fue la FG estimada por CG (FGeCG) con 59.7 y 81.77% de las mediciones dentro del 15 y 30% respectivamente. El coeficiente de correlación de concordancia entre la FG por CKD-EPI y MDRD-4 fue de 0.97, con CG y CG-SC de 0.78 y 0.85, respectivamente. Conclusiones: la fórmula alterna más exacta para estimar la filtración glomerular en esta población colombiana es la MDRD-4 que tiene una alta concordancia con la fórmula de CKD-EPI. Se sugiere no utilizar la estimación de la FG con la fórmula de CG.

ABSTRACT

Resumen Introducción: la diabetes mellitus tipo 2 (DM2) es la principal causa de nefropatía terminal en el mundo. Se sabe que en Colombia esta enfermedad tiene una prevalencia del 7-9 %, pero para algunos municipios no hay datos sobre el número de personan que padecen DM2 y enfermedad renal crónica (ERC), ni sobre los factores de riesgo relacionados con su desarrollo. Objetivo: determinar la prevalencia y los factores de riesgo para desarrollar ERC en una población de pacientes con DM2 que consultaron a un programa de riesgo cardiovascular de una institución de salud de Armenia, Colombia, durante el año 2017. Materiales y métodos: estudio descriptivo de corte transversal realizado en una muestra de 232 pacientes. Se describieron las variables con medidas de tendencia central e intervalos de confianza del 95 %, se realizó análisis de varianza y pruebas Chi cuadrado para las variables numéricas y categóricas, respectivamente; se aplicaron los modelos de regresión múltiple y regresión logística, y se consideró una diferencia estadísticamente significativa con un valor de p<0,05. Resultados: la prevalencia de DM2 fue del 34,14 % y la de ERC varió entre 22,41 % y 38,79 %, según la ecuación utilizada. El 69,83 % de la población se encontró en normoalbuminuria; el 25 %, en microalbuminuria, y el 5,17 °%, en macroalbuminuria. Los factores de riesgo identificados para ERC fueron edad (Cockcroft-Gault y CKD-EPI p<0,001; MDRD p=0,012), perímetro abdominal (Cockcroft-Gault p<0,001; MDRD p=0,028; CKD-EPI p=0,011), nivel de creatinina (Cockcroft-Gault, MDRD, CKD-EPI p<0,001) y sedentarismo (Cockcroft-Gault p=0,046). Las ecuaciones más adecuadas para identificar tempranamente la ERC en la población estudiada fueron CKD-EPI (R2=85,74 %) y Cockcroft-Gault (R2=85,43 %), con un valor de pronóstico de 95,68 % y 93,96 %, respectivamente. Conclusión: la prevalencia de ERC, que osciló entre 22,41 % y 38,79 %, dependió de la ecuación utilizada. Los factores de riesgo para desarrollar ERC fueron edad, nivel de creatinina, perímetro abdominal y sedentarismo. Se propone que para esta población las ecuaciones Cockcroft-Gault y CKD-EPI son las más adecuadas para identificar la ERC.


Abstract Introduction: In Colombia, the prevalence of type 2 diabetes mellitus (DM2) is 7-9%, this being the main cause of end-stage renal disease in the world4. In the municipality of Armenia, the prevalence of the population suffering from DM2 with chronic kidney disease (CKD) and the risk factors related to its development are unknown. Objective: To determine the prevalence and risk factors of developing chronic kidney disease (CKD) in a population with type 2 diabetes, consultants to a cardiovascular risk program of an IPS of Armenia, Colombia, during the year 2017. Methods: Descriptive cross-sectional study with 232 patients. The variables were described by measures of central tendency and 95 % confidence intervals, ANOVA and Chi square tests were performed for the numerical and categorical variables respectively, multiple regression and logistic regression, with a value of P <0.05. Results: The prevalence of diabetes was 34.14 % and CKD varies between 22.41-38.79 % according to the equation used. 69.83 % are in normoalbuminuria, 25 % in microalbuminuria and 5.17 % in macroalbuminuria. The risk factors identified for CKD were: age (Cockcroft-Gault and CKD-EPI p <0.001; MDRD p = 0.012), abdominal perimeter (Cockcroft-gault p <0.001; MDRD p = 0.028; CKD-EPI p = 0.011), creatinine level (Cockcroft-gault, MDRD, CKD-EPI p <0.001) and sedentary lifestyle (Cockcroft-gault p = 0.046). The most adequate equations for early identification of CKD in this population are CKD-EPI (R2 = 85.74 %) and Cockcroft-gault (R2 = 85.43 %), with a prognostic value of 95.68 % and 93, 96 % respectively. Conclusion: The prevalence of CKD varies between 22.41 % and 38.79 %, depending on the equation used. The risk factors for developing CKD are age, creatinine level, abdominal perimeter and sedentary lifestyle. It is proposed that for this population the Cockcroft-Gault and CKD-EPI equations are the most adequate to identify CKD.

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.
