RESUMO
Abstract Introduction: Living donor kidney transplantation is considered the ideal renal replacement therapy because it has a lower complication rate and allows an efficient response to the high demand for grafts in the healthcare system. Careful selection and adequate monitoring of donors is a key element in transplantation. Individuals at greater risk of developing kidney dysfunction after nephrectomy must be identified. Objective: To identify risk factors associated with a renal compensation rate (CR) below 70% 12 months after nephrectomy. Methods: This observational retrospective longitudinal study included living kidney donors followed up at the Lower Amazon Regional Hospital between 2016 and 2022. Data related to sociodemographic variables, comorbid conditions and kidney function parameters were collected. Results: The study enrolled 32 patients. Fourteen (43.75%) had a CR < 70% 12 months after kidney donation. Logistic regression found obesity (Odds Ratio [95%CI]: 10.6 [1.7-65.2]), albuminuria (Odds Ratio [95%CI]: 2.41 [1.2-4.84]) and proteinuria (Odds Ratio [95%CI]: 1.14 [1.03-1.25]) as risk factors. Glomerular filtration rate was a protective factor (Odds Ratio [95% CI]: 0.92 [0.85-0.99]). Conclusion: Obesity, albuminuria and proteinuria adversely affected short-term renal compensation rate. Further studies are needed to uncover the prognostic implications tied to these risk factors. Our findings also supported the need for careful individualized assessment of potential donors and closer monitoring of individuals at higher risk.
Resumo Introdução: O transplante de rim de doador vivo é considerado a terapia renal substitutiva ideal por oferecer menor taxa de complicações e possibilitar uma resposta eficiente à grande demanda por enxertos no sistema de saúde. A seleção criteriosa e o acompanhamento adequado dos doadores constituem um pilar fundamental dessa modalidade terapêutica, sendo essencial a identificação dos indivíduos em maior risco de disfunção renal pós-nefrectomia. Objetivo: Identificar fatores de risco para uma Taxa de Compensação (TC) da função renal inferior a 70% 12 meses após a nefrectomia. Métodos: Estudo observacional, retrospectivo e longitudinal conduzido com doadores de rim vivo acompanhados no Hospital Regional do Baixo Amazonas entre 2016 e 2022. Foram coletados dados correspondentes a variáveis sociodemográficas, comorbidades e parâmetros de função renal. Resultados: Foram incluídos 32 pacientes na amostra final. Destes, 14 (43,75%) obtiveram TC < 70% 12 meses após a doação. A regressão logística identificou a obesidade (Odds Ratio [IC95%]: 10.6 [1.7-65.2]), albuminúria (Odds Ratio [IC95%]: 2.41 [1.2-4.84]) e proteinúria (Odds Ratio [IC95%]: 1.14 [1.03-1.25]) como fatores de risco. A taxa de filtração glomerular atuou como fator de proteção (Odds Ratio [IC95%]: 0.92 [0.85-0.99]). Conclusão: Obesidade, albuminúria e proteinúria demonstraram impacto negativo na taxa de compensação renal em curto prazo, o que reitera a necessidade de estudos acerca das implicações prognósticas desses fatores. Além disso, reforça-se a necessidade de avaliação cuidadosa e individualizada dos possíveis doadores, com acompanhamento rigoroso, especialmente para indivíduos de maior risco.
RESUMO
Hypertension is a non-communicable disease in which the pressure of blood pushing against the arterial walls becomes high. In chronic stage it leads to severe systemic diseases, which affects heart, kidney, lung etc. The main causative factors are unhealthy food and lifestyle, stress, smoking, Alcohol, obesity and hereditary. Microalbuminuria in Hypertension is an early sign of kidney damage and is considered as a predictor for the end stage of renal disease and cardiovascular disease. So, it is of great importance to manage microalbuminuria or high urine albumin creatinine ratio and progression of kidney disease in hypertensive patient. In Ayurveda references no proper description of hypertension is available. By viewing the pathogenesis and physiology, it is formed by the involvement of Tridoshas, Srotorodha, and Dhatudushti. The present case is a 60-year male patient was diagnosed uncontrolled hypertension with microalbuminuria, admitted for 1month, presented with complaints such as frothy urine, over tiredness, uncontrolled anger and increased blood pressure during evening time, not controlled by hypertensive modern medicines. His urine albumin-creatinine ratio was 106.98 mg/dl of creatinine, microalbumin in urine 138 mg/dl and uric acid was 11.5 mg/dl. He was advised the internal Ayurveda medicines, diet restriction and yogic breathing exercise. Within one month of treatment the urine albumin creatinine ratio and uric acid was reduced and became normal. His blood pressure also became controlled and recovered all symptoms. Ayurvedic treatment module appears to be safe and efficacious with early recovery and better outcomes in this case.
RESUMO
Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75：3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ2=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.
RESUMO
Objective:To investigate the efficacy of Tanzhuo Decoction in the treatment of early diabetic nephropathy in patients with type 2 diabetes mellitus and its effect on cystatin C (Cys-C), C-reactive protein (CRP), urinary albumin excretion rate (UAER), and creatinine clearance rate (CCr). Methods:Eighty patients with type 2 diabetes mellitus complicated by early diabetic nephropathy who received treatment at Maanshan Hospital of Traditional Chinese Medicine from 2019 to 2021 were included in this randomized controlled study. They were divided into a control group ( n = 40) and a treatment group ( n = 40) using the random number table method. Patients in the control group received conventional therapy including blood glucose and blood pressure control, while those in the treatment group received Tangzhuo Decoction in addition to the same treatment as that given to the control group. Both groups of patients were treated for 30 days. The clinical efficacy as well as pre- and post-treatment Cys-C, CRP, UAER, and CCr were compared between the two groups. Results:The total response rate in the treatment group was 92.5% (37/40), which was significantly higher than 75.0% (30/40) in the control group ( χ2 = 4.50, P < 0.05). After treatment, Cys-C, CRP, and UAER in the treatment group were (2.04 ± 0.08) mg/L, (3.97 ± 1.71) mg/L, and (91.18 ± 18.68) μg/min, respectively, which were significantly decreased compared with those before treatment ( t = 12.14, 5.59, 4.73, all P < 0.05). After treatment, CCr in the treatment group was (56.3 ± 5.01) mL/min, which was significantly increased compared with that before treatment ( t = -8.56, P < 0.05). After treatment, Cys-C, CRP, and UAER in the control group were (2.17 ± 0.04) mg/L, (4.66 ± 1.47) mg/L, and (103.93 ± 22.62) μg/min, respectively, which were significantly decreased compared with those before treatment ( t = 4.05, 5.00, 2.24, all P < 0.05). After treatment, CCr in the control group was (45.9 ± 4.9) mL/min, which was significantly increased compared with that before treatment ( t = -3.98, P < 0.05). There were significant differences in Cys-C, UAER, and CCr between the treatment and control groups ( t = -7.42, -2.29, 7.82, all P < 0.05). Conclusion:Tanzhuo Decoction for the treatment of early diabetic nephropathy in patients with type 2 diabetes mellitus has a definite effect. It can effectively reduce levels of Cys-C and UAER, reduce inflammatory reactions, improve kidney function, and delay the progression of kidney injury.
RESUMO
Background: Inflammatory markers are excessively produced by adipocytes in T2DM due to obesity-induced dysregulation of adipocytes. Inflammation is recognised by elevated level of inflammatory markers like C-reactive protein. It has been reported that patients with nephropathy and those with albuminuria have higher levels of inflammatory markers. Methods: Study design observational descriptive cross-sectional study. 150 subjects having age more than 30 years and less than 55 years diagnosed with type 2 diabetes mellitus were included. HbA1c, FPG, creatinine, urea, CRP, and albuminuria were analysed. Results: A strong and statistically significant correlation was seen between serum CRP levels and albuminuria levels with a p value of 0.831 and a p value of 0.00. The study group was divided into two groups with normal CRP (n=40) and elevated CRP (n=110). Average values of all parameters showed a statistically significant increase in the group with abnormal CRP levels. In the ROC analysis, an area of .957 under the curve shows a very high predictive value of 15.5 mg/l of CRP for predicting albuminuria in patients of T2DM. Conclusions: From our results, we have been able to establish a strong association as well as a predictive relationship between the level of CRP and albuminuria in T2DM. We have shown that serum CRP levels at a cut-off of 15.5 mg/l are a predictor of clinically significant albuminuria. This makes serum CRP level an effective screening tool for albuminuria.
RESUMO
Background: Diabetes mellitus (DM) is a common metabolic disease. Anaemia is a common accompaniment to diabetes, particularly in patients with albuminuria or reduced renal function. Anaemia is more frequent and more severe at any level of glomerular filtration rate (GFR) in diabetics compared to nondiabetic patients. Methods: One hundred patients with type 2 diabetes mellitus were included in the study. Complete blood count, serum iron profile, ferritin, vitamin B12 and folate, kidney function tests and urine albumin creatinine ratio were assessed for these patients. Estimated glomerular filtration rate (eGFR) was calculated with MDRD-4 variable formula. Results: Fifty-four patients (54%) were found to be anaemic. Serum ferritin <50 µg/l was taken as cut off for defining iron deficiency anaemia. 21 patients had iron deficiency anaemia (IDA) and 33 had anaemia of chronic disease (ACD). Serum vitamin B12 and folate levels were within normal limits in all the patients. There was a rise in the prevalence of anaemia from 25.9% in patients with a normal ACR to 59.2% in those with microalbuminuria and to 75% in macroalbuminuria. Conclusions: Any degree of renal impairment and albuminuria are the risk factors for anaemia in these patients. Hence screening, characterization and treatment of aneamia in type 2 DM may be helpful in management of these patients.
RESUMO
Introduction:Metabolic syndrome (MetS) predicts cardiovascular disease, and patients with this condition and type 2 diabetes have increased albuminuria, significantly impacting cardiovascular mortality and kidney disease progression. A considerable number of interventions to control MetS exist and are considered efficient, including the use of medication and changes in lifestyle. However, which approaches are effective in controlling albuminuria remains unclear. This systematic review protocol aims to map in the available literature whether lifestyle, medication, and surgical intervention for MetS have an impact on reducing albuminuria in adult patients. Methods: The Joanna Briggs Institute methodology for systematic reviews will be followed. Cochrane Database of Systematic Reviews, Scopus, Embase, and MEDLINE/PubMed databases will be used. For the Gray Literature, the DART-Europe E-theses Portal. There will be no language restriction. Studies written after 2009 will be included due to the consensus and definition of metabolic syndrome. This review will include studies considering pharmacological and non-pharmacological treatments for controlling albuminuria in patients with MetS. Studies where MetS is described in children and adolescents, animals, pregnant women, and patients with type 1 diabetes will be excluded. First, the selection will be based on reading the title and summary of the texts retrieved in the search strategy, followed by reading the relevant texts in full by two reviewers. After the selection of the studies, the extraction of the data, analysis, and synthesis will be conducted according to the JBI methodology

ABSTRACT Introduction: The albumin-to-creatinine ratio and total protein-to-creatinine ratio in spot urine samples have already been validated as surrogates for 24-hour albuminuria and proteinuria measurements. Thus, we hypothesized that the type of proteinuria, detected by the electrophoretic pattern of 24-hour urine, could be predicted by the simple proportion of albumin in the total urine protein content, using the albumin-to-protein ratio (APR). Our study sought to validate the use of APR as a cheaper substitute for urinary protein electrophoresis (UPE). Methods: Using different mathematical models, we compared, the albumin fraction in 24-hour urine samples by electrophoresis and the APR ratio in spot samples from 42 outpatients with chronic kidney disease (CKD). Results: A strong log-order correlation r = 0.84 (0.75-0.92; 95% CI, p = 0.001) was observed between APR and the albumin fraction in the UPE. Conclusion: The APR can substitute electrophoresis in CKD outpatients.
Resumo Introdução: A utilização da razão albumina/creatinina e da razão proteína total/creatinina em amostras isoladas de urina já foram validadas como substitutos para a albuminúria e proteinúria em 24 horas. Assim, nossa hipótese é que o tipo de proteinúria, dado pelo padrão eletroforético da urina de 24 horas, poderia ser previsto pela simples proporção de albumina no conteúdo total de proteínas na urina, utilizando a razão albumina/proteína (RAP). O presente estudo procurou validar o uso da RAP como um substituto mais prático e de menor custo da eletroforese de proteínas urinárias (EPU). Métodos: Foram utilizados diferentes modelos matemáticos a fim de comparar a fração de albumina pela eletroforese em amostras de urina de 24 horas e a RAP em amostras isoladas em 42 pacientes ambulatoriais com doença renal crônica. Resultados: Foi observada uma forte correlação logarítmica r = 0,84 (0,75-0,92; 95% CI, p = 0,001) entre a RAP e a fração de albumina pela EPU. Conclusão: A RAP pode substituir a eletroforese urinária em pacientes renais crônicos ambulatoriais.
RESUMO
Abstract Background: The state of Aguascalientes, Mexico, has been recognized as a chronic kidney disease hotspot. Screening studies have revealed a high prevalence of persistent albuminuria (pA), histologically characterized by glomerulomegaly, and incomplete podocyte fusion, probably associated with oligonephrony. To date, urinary biomarkers have not been explored in this population. Objective: The aim of the study was to identify the presence of potential biomarkers of early renal injury in patients with pA (pACR) and that correspond with the characteristic nephropathy profile that prevails in this entity. Methods: This is a cross-sectional, analytical, and comparative study. Four groups were recruited: adolescents aged 10-17 years with pACR, isolated albuminuria (iACR), no albuminuria (negative control), and adults with biopsy-confirmed glomerulopathy (positive control). Urinary excretion of SerpinA3, heat-shock protein-72 (HSP-72), podocalyxin (PCX), and nephrin was evaluated in urine samples. SerpinA3 and HSP-72 were analyzed by Western blot, and PCX and nephrin were quantified by enzyme-linked immunosorbent assay. Results: The mean GFR in the pACR group was 113.4 mL/min/1.73m2 and differed significantly only from that of the positive control group (65.1 mL/min/1.73m2). The mean albuminuria value in the pACR group was 48.9 mg/g. SerpinA3 concentration differed between groups (0.08 vs. 0.25 ng/mL, p < 0.001): it was significantly higher in the pACR group compared to the negative controls (p = 0.037). Conclusion: SerpinA3 was significantly associated with pA and could become a biomarker of early kidney injury. Further investigations are required to determine whether SerpinA3 precedes the development of albuminuria and its pathogenic role.
RESUMO
Objective:To explore the relationship between urinary exosomal microRNA (exo-miR) - 155 in patients with type 2 diabetes mellitus (T2DM) and the onset and severity of diabetic kidney disease (DKD).Methods:From January to May 2019, 5 patients with T2DM normoalbuminuria and 5 patients with type 2 DKD were recruited from the Department of Endocrinology and Metabolism of Chongming Hospital of Shanghai Health Medical College as a microRNA screening cohort. Urine samples were collected to extract urinary exosomes, and the urine exo-miR spectrum was detected and analyzed using the miRCURY LNA array. From June 2019 to October 2022, 351 patients with T2DM who met the enrollment criteria and were matched by age and sex were included in the validation cohort in the Department of Endocrinology and Metabolism of the hospital. Patients were divided into 3 groups according to urinary albumin/creatinine ratio (UACR): normoalbuminuria group (UACR<30 mg/g, n=143), microalbuminuria group (30 mg/g≤UACR≤300 mg/g, n=171) and macroalbuminuria group (UACR>300 mg/g, n=37). According to DKD diagnostic guidelines, microalbuminuria group and macroalbuminuria group were classified into DKD group. Real-time fluorescence quantitative PCR was used to detect the expression level of exo-miR-155 in urine. Results:The results of transmission electron microscopy, nanoparticle tracking analysis, and Western blotting showed that the extraction of exosome vesicles was successful. In the screening cohort, according to the screening criteria of P<0.05 and fold changes (FC)>1.5, 226 differentially expressed miRNAs were identified from the urinary exosomes of the DKD group compared to the T2DM group. Among them, miR-155 ranged highest (FC=32.75, P<0.001). In the validation cohort, compared with the normoalbuminuria group [0.76 (0.55, 0.95)], the macroalbuminuria group [1.84 (1.18, 2.42)] had the most significant increase in urinary exo-miR-155 level ( Z=-7.411, P<0.001), followed by the microalbuminuria group [0.86 (0.69, 1.25)] ( Z=-4.092, P<0.001), and the urinary exo-miR-155 level in the macroalbuminuria group was significantly higher than that in the microalbuminuria group ( Z=-5.841, P<0.001). The correlation analysis showed that urinary exo-miR-155 level was positively correlated with UACR ( r s=0.329, P<0.001) and negatively correlated with estimated glomerular filtration rate ( r s=-0.249, P=0.015). The results of receiver operating characteristic curve analysis showed that the area under the curve of urinary exo-miR-155 level predicted DKD progression in T2DM patients was 0.892 (95% CI 0.859-0.925), corresponding cutoff value was 0.982, and the sensitivity and specificity were 71.9% and 87.7%, respectively. Multivariate logistic regression analysis showed that urinary exo-miR-155≥0.982 was an independent risk factor for progression to DKD in T2DM patients ( OR=3.310, 95% CI 1.981-5.530, P<0.001). Conclusion:The expression level of urinary exo-miR-155 is increased in T2DM patients with microalbuminuria and macroalbuminuria, which is related to the degree of albuminuria, and can be used as a predictive marker to identify potential DKD.
RESUMO
Objective:To investigate the correlation between Helicobacter pylori ( H.pylori) infection and albuminuria inphysical examination population. Methods:It was a cross-sectional study. All the adults who received physical examination and underwent 13C-urea breath test at the Physical Examination Center in Tongji Hospital in 2021 were selected as the study subjects. General data (such as demographic information and past medical history) were documented. The physical measurement and blood biochemical indicators were checked too. Multivariate analysis was used to analyze the relationship between H. pylori infection and albuminuria. Results:A total of 30 311 subjects were included in this analysis. There were 17 123 males and 13 188 females with an age of (44.51±12.17) years. The positive rate of H. pylori infection was 27.3%. The incidence of albuminuria in subjects with H. pylori infection was 6.7%, and it was 6.1% in the subjects without H. pylori infection ( P=0.031). After adjusting for the confounding factors such as gender, age, diabetes and hypertension, H. pylori infection was independently associated with the risk of albuminuria (odds ratio ( OR)=1.133, 95% CI: 1.018-1.261, P=0.022). Conclusion:H. pylori infection is positively correlated with the occurrence of albuminuria in the physical examination population.
RESUMO
Objective:To explore the relationship between metabolic score for insulin resistance (METS-IR) and chronic kidney disease (CKD) and albuminuria in the Chinese population.Methods:This cross-sectional study was conducted from January to December 2018 among residents aged 20 to 70 years in ten regions of eight provinces in China; all residents had lived in their region for more than 5 years. Various parameters were measured, included fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin (HbA 1c), blood lipids, renal function, urinary albumin/creatinine ratio (UACR), etc. Data of 5 060 subjects meeting the criteria were included in the study. CKD was defined as estimated glomerular filtration rate (eGFR)<60 ml·min -1·1.73 m -2 or UACR≥30 mg/g. Albuminuria was defined as UACR≥30 mg/g. METS-IR was calculated and categorized into quartiles: Q1, METS-IR≤32.19; Q2, METS-IR 32.20-37.10; Q3, METS-IR 37.11-42.58; and Q4, METS-IR>42.58. The correlation between METS-IR and CKD and albuminuria was analyzed by binary logistic regression, and subgroup analyses were performed. Results:There were 1 266, 1 266, 1 265, and 1 263 participants included in Q1-Q4 groups, respectively. With the increase of METS-IR quartile, various parameters increased, including age, fasting blood glucose, HbA 1c, triglycerides, serum uric acid, waist circumference, body mass index, and systolic and diastolic blood pressure, and the proportion of males also increased (all P<0.05). The proportion of patients with CKD and albuminuria increased significantly with the increase in interquartile range (Q) of METS-IR (all P<0.05). Logistic regression analysis showed that for every 1-unit increment of METS-IR, the risk of CKD and albuminuria were both increased by 2% [for both: odds ratio ( OR)=1.02, 95% confidence interval ( CI) 1.01-1.03]. Compared with the lowest METS-IR group (Q1), the ORs for CKD and albuminuria in the highest METS-IR group (Q4) were 1.57 (95% CI 1.17-2.10) and 1.46 (95% CI 1.09-1.96), respectively. In the subgroup analyses, increased METS-IR was significantly associated with CKD and albuminuria among women (CKD: OR=1.62, 95% CI 1.14-2.31; albuminuria: OR=1.53, 95% CI 1.07-2.18), individuals with HbA 1c<7% ( OR=1.64, 95% CI 1.21-2.23; OR=1.55, 95% CI 1.14-2.11), individuals with eGFR≥90 ml·min -1·1.73 m -2 ( OR=1.78, 95% CI 1.27-2.49; OR=1.80, 95% CI 1.28-2.53), and the Chinese Han population ( OR=1.56, 95% CI 1.13-2.17; OR=1.41, 95% CI 1.01-1.96). Conclusions:METS-IR is significantly associated with CKD and albuminuria in a Chinese population. Furthermore, the higher the METS-IR, the higher the risk of CKD and albuminuria.
RESUMO
Objective:To investigate the prevalence of albuminuria in Chinese residents aged >35 years and its potential association with cardiovascular disease (CVD).Methods:A total of 34 647 Chinese subjects aged ≥35 years were selected by stratified multi-stage random sampling from 2012 to 2015. Data were collected through questionnaires, physical examinations, and laboratory tests. Albuminuria was categorized into 3 types according to urinary albumin-to- creatinine ratio: normal (<30 mg/g), microalbuminuria (MAU, 30-300 mg/g), and macroalbuminuria (≥300 mg/g). Measurement data were expressed as xˉ±s, and t-tests were used for comparisons between indicators. Qualitative data were expressed as rate or constituent ratio, and the χ2 test or Kruskal-Wallis test was used to examine differences. Logistic regression was used for multivariate analyses. SAS 9.4 software was used for statistical analyses, and P<0.05 was considered statistically significant. Results:The prevalence of abnormal albuminuria was 19.1%; the prevalence was 17.2% for MAU and lower in males (13.8%) than females (20.1%, P<0.01). The risk of CVD was higher among subjects with MAU ( OR=1.23, 95% CI 1.12-1.35) and macroalbuminuria ( OR=1.86, 95% CI 1.50-2.32). When MAU was complicated by hypertension and diabetes mellitus, the CVD risk was 1.76 times higher. Conclusions:The prevalence of MAU is high among Chinese subjects aged 35 years and over. Those with MAU have higher CVD risk, especially those with hypertension and diabetes mellitus.

Objective:To investigate the efficacy of dapagliflozin in patients with diabetic nephropathy.Methods:A total of 82 patients with early diabetic nephropathy who were treated in Wuhu No.1 People′s Hospital from January 2020 to December 2021 were selected as the research objects, and they were divided into the conventional group (41 cases) and the dapagliflozin group (41 cases) according to the random number table method. The patients in the conventional group were given original hypoglycemic treatment and the patients in the dapagliflozin group were given dapagliflozin treatment on the former basis, the patients in the two groups were treated for 12 weeks. The levels renal function index, blood glucose index, glomerular filtration index and the occurrence of adverse reactions during the treatment period were compared between the two groups.Results:After treatment, the total clinical effective rate in the dapagliflozin group was higher than that in the conventional group: 95.12%(39/41) vs. 78.05%(32/41), there was statistical difference ( χ2 = 4.96, P<0.05). The levels of urine albumin/creatinine (UACR), blood urea nitrogen (BUN) , serum creatinine (SCr), fasting blood glucose (FPG), 2 h postprandial blood glucose (2 h PG), glycosylated hemoglobin (HbA 1c), cystatin C (Cys-C) in the dapagliflozin group were lower than those in the conventional group: (49.73 ± 11.65) mg/g vs. (67.26 ± 10.04) mg/g, (6.96 ± 0.54) mmol/L vs. (7.25 ± 0.48) mmol/L, (76.82 ± 2.86) μmol/L vs. (78.59 ± 3.06) μmol/L, (8.58 ± 0.18) mmol/L vs. (8.80 ± 0.32) mmol/L, (8.03 ± 0.42) mmol/L vs. (8.56 ± 0.44) mmol/L, (7.06 ± 0.57)% vs. (7.52 ± 1.06)%, (1.47 ± 0.50) mg/L vs. (1.84 ± 0.55) mg/L, there were statistical differences ( P<0.05). The level of glomerular filtration rate (GFR) between the two groups had no significant differences ( P>0.05). The incidence of total adverse reactions in dapagliflozin group was lower than that in control group: 7.32%(3/41) vs. 24.39%(10/41), there was statistical difference ( P<0.05). Conclusions:Dapagliflozin has a good effect in the treatment of patients with early diabetic nephropathy. It can lower glucose, improve Cys-C, reduce urinary microalbumin and protect renal function.

Related factors of albuminuria in T2DM patients were explored by multivariate Logistic regression analysis． In addition ，receiver operating characteristic (ROC) curve analysis was applied to evaluate the predictive value of Lp-PLA2 for albuminuria in T2DM patients. @*Results@#Lp-PLA2 was significantly higher in the macroalbuminuria group than that in both the normal group and the microalbuminuria group，and the differences were statistically significant (P＜0. 05) ．Compared with the normal group，Lp-PLA2 in the microalbuminuria group increased(P＜0. 05) ．With the increase in Lp-PLA2 tertile， there was gradual increase in UACR , and the difference was statistically significant (P＜0. 05) ．Correlation analysis showed that Lp-PLA2 was positively correlated with duration of DM，systolic blood pressure (SBP) ，glycosylated hemoglobin (HbA1c) ，fasting blood glucose (FBG) ，blood urea nitrogen (BUN) ，serum creatinine (Scr) ，UACR and negatively correlated with estimated glomerular filtration rate ( eGFR) (P ＜0. 05 ) ． Multivariate Logistic regression analysis showed that Lp-PLA2 ［OR = 1. 046，95% CI( 1. 031，1. 060) ］was an independent risk factor for albuminuria (P＜0. 05) ．The AUC of Lp-PLA2 for predicting albuminuria was 0. 902 ［95% CI(0. 862，0. 942) ］. The cut-off value of Lp-PLA2was 148 ng / ml，the sensitivity was 65. 7% and specificity was 98. 5%．@*Conclusion@#Lp-PLA2 is closely related to the albuminuria in T2DM patients，which provides a new method for the diagnosis and treatment of diabetic kidney disease (DKD) .
RESUMO
ABSTRACT BACKGROUND: Albuminuria is a risk factor for microvascular and macrovascular complications in the diabetic population. However, few studies have correlated poor glycemic control and albuminuria prevalence in Hispanic populations. OBJECTIVE: To evaluate the association between glycemic control and albuminuria among Peruvian adults with type 2 diabetes mellitus (T2DM). DESIGN AND SETTING: Cross-sectional analytical study among adults with T2DM in Lima, Peru. METHODS: We included adults over 18 years old who were in a clinical follow-up program at a private clinic in Lima in 2018. Poor glycemic control was defined as a serum value of glycosylated hemoglobin A1C (HbA1C) ≥ 7%. Albuminuria was defined as albumin values > 30 mg/dl in the first morning urine. We generated generalized linear regression models from the Poisson family with robust variance. We calculated the crude and adjusted prevalence ratios (PRs) with their 95% confidence interval (CI). RESULTS: We analyzed 907 participants of median age 58 years (interquartile range, IQR 49 to 66), and 62.8% were males. The prevalence of poor glycemic control was 39.8%, and the prevalence of albuminuria was 22.7%. The prevalences of albuminuria in groups with poor glycemic control and adequate glycemic control were 32.7% and 16.1%, respectively. In the adjusted regression analysis, we found a statistically significant association between poor glycemic control and albuminuria (annual percentage rate, aPR = 1.70; 95% CI: 1.28-2.27). CONCLUSIONS: The prevalence of poor glycemic control and albuminuria was high in our study population. Moreover, Peruvian T2DM adults with poor glycemic control were more likely to have albuminuria.
RESUMO
Fundamento: el concepto de microalbuminuria se introdujo como un marcador temprano de nefropatía diabética y mortalidad. La microalbuminuria se ha convertido en un marcador pronóstico de riesgo cardiovascular tanto en diabéticos como en no diabéticos. Objetivo determinar el comportamiento de la microalbuminuria y los factores de riesgo cardiovasculares en pacientes diabéticos pertenecientes al consultorio médico número 25 del Policlínico Docente Comunitario Presidente Salvador Allende. Métodos: se realizó un estudio descriptivo de corte transversal, de un universo de 1125 personas, se obtuvo una muestra de 62 pacientes con diabetes mellitus. La investigación se realizó de enero a diciembre del 2018. El diagnóstico de microalbuminuria se realizó después de dos determinaciones confirmadas de las tres realizadas en un período de 6 meses, por lo que quedaron dos grupos de pacientes según la presencia o ausencia de microalbuminuria, la cual se relacionó con factores de riesgo cardiovasculares. Las variables descriptivas se expresaron en porcentajes y para la comparación de dos variables en estudio se utilizó el método estadístico de Chi cuadrado. Resultados: el 11,3 % de los pacientes diabéticos presentaron microalbuminuria. El 100 % de los pacientes diabéticos con microalbuminuria positiva, padecen de hipertensión arterial. El 71,43 % de los pacientes diabéticos, con microalbuminuria positiva presentaron dislipidemia. El 71,43 % de los pacientes diabéticos con microalbuminuria positiva son obesos. Conclusiones: en los pacientes diabéticos con microalbuminuria positiva los factores de riesgo cardiovasculares que se relacionaron fueron: la hipertensión arterial, la dislipidemia y la obesidad.
Background: the concept of microalbuminuria was introduced as an early marker of diabetic nephropathy and mortality. Microalbuminuria has become a prognostic marker of cardiovascular risk in both diabetics and non-diabetics. Objective: to determine the behavior of microalbuminuria and cardiovascular risk factors in diabetic patients belonging to medical office number 25 of the Presidente Salvador Allende Community Teaching Polyclinic. Methods: a descriptive cross-sectional study was carried out, from a universe of 1125 people, a sample of 62 patients with diabetes mellitus was obtained. The investigation was carried out from January to December 2018. The diagnosis of microalbuminuria was made after two confirmed determinations of the three carried out in a period of 6 months, so there were two groups of patients according to the presence or absence of microalbuminuria, the which was related to cardiovascular risk factors. The descriptive variables were expressed in percentages and the Chi-square statistical method was used to compare the two variables under study. Results: 11.3 % of diabetic patients presented microalbuminuria. 100 % of diabetic patients with positive microalbuminuria suffer from arterial hypertension. 71.43 % of diabetic patients with positive microalbuminuria presented dyslipidemia. 71.43 % of diabetic patients with positive microalbuminuria are obese. Conclusions: in diabetic patients with positive microalbuminuria, the cardiovascular risk factors that were related were: arterial hypertension, dyslipidemia and obesity.
RESUMO
Abstract Introduction: Screening patients with diabetes mellitus (DM) for chronic kidney disease (CKD) enables early diagnosis and helps to establish adequate treatment and avoid possible damages to health associated with disease progression. This study aimed to verify whether screening for CKD has been properly conducted in populations with diabetes mellitus seen at primary care clinics. Methods: This descriptive study included 265 individuals with DM seen at Basic Healthcare Clinics in Divinópolis, MG, Brazil. Clinical and laboratory data were collected from the Integrated Health System. Frequency of testing and kidney function evaluations performed within the last 12 months were calculated along with the proportion of patients with increased urinary albumin excretion (UAE) and decreased glomerular filtration rate (GFR) to determine the proportion of patient with kidney involvement. Results: We found that 41.2% of the patients had kidney involvement and that 61.2% of the individuals with kidney involvement were on nephroprotective medication. Of the 21.9% tested for isolated albuminuria, 46.5% had increased UAE. The albumin-to-creatinine ratio (ACR) was measured in 12.1% of the patients, with 43.8% having an increased ACR. We found that 89.0% of the patients had their serum creatinine levels measured, and that 33.1% had a decreased GFR. Conclusion: CKD screening was more frequently performed via the GFR than UAE, a parameter analyzed only in a small proportion of patients. Therefore, CKD screening for patients with diabetes is not being performed properly in primary care.
Resumo Introdução: O rastreio da doença renal crônica (DRC) em pacientes com diabetes (DM) possibilita o diagnóstico precoce e ajuda a estabelecer um tratamento adequado, evitando possíveis danos à saúde pela progressão da doença. O objetivo deste trabalho foi verificar se o rastreio da DRC está sendo feito de maneira adequada entre diabéticos acompanhados na atenção primária à saúde. Métodos: Estudo descritivo com 265 pacientes com DM atendidos nas Unidades Básicas de Saúde de Divinópolis, MG. A coleta de dados clínicos e laboratoriais foi realizada por meio de consulta ao Sistema Integrado de Saúde. Foram calculadas a frequência de realização dos exames de avaliação da função renal nos últimos 12 meses e a frequência de pacientes com excreção urinária de albumina (EUA) aumentada e a taxa de filtração glomerular (TFG) reduzida, e assim determinada a frequência de pacientes com comprometimento renal. Resultados: Foi observado que 41,2% dos pacientes têm comprometimento renal; dentre esses, 61,2% utilizam algum medicamento nefroprotetor. Apenas 21,9% realizaram o exame de albuminúria isolada, dos quais 46,5% apresentaram albuminúria aumentada. O exame de relação albumina/creatinina (RAC) foi realizado por 12,1% dos pacientes, dos quais 43,8% apresentaram RAC aumentada. Foi observado que 89,0% dos pacientes realizaram o exame de creatinina sérica, dos quais 33,1% apresentaram TFG reduzida. Conclusão: Foi observado maior índice de rastreio da DRC por meio da TFG em relação ao rastreio por meio da EUA, o qual foi realizado por pequeno número de pacientes. Portanto, o rastreio da DRC não está sendo realizado adequadamente na atenção básica ao diabético.
RESUMO
Contexto al realizar cribado en la población de riesgo se encontró que la enfermedad renal crónica subclínica (ERCs) está escasamente caracterizada en Chile y su conocimiento contribuiría al mejor manejo y tratamiento precoz, atenuando sus consecuencias. Objetivo describir las características epidemiológicas y clínicas de la población con ERCs en Chile. Metodología estudio descriptivo transversal en una población de 1032 sujetos provenientes de tres regiones de Chile: Coquimbo (n = 902), Metropolitana (n = 70) y De Los Ríos (n = 60), provenientes de programas cardiovasculares, otros programas de APS y familiares directos de pacientes en diálisis. A los pacientes se les aplicó: un consentimiento informado, una encuesta, un examen físico (presión arterial, peso y talla) y se realizaron exámenes de laboratorio (creatininemia y albuminuria/creatininuria). Se definió ERC por guía KDOQI-2012 y velocidad de filtración glomerular según MDRD. La albuminuria se midió mediante relación albuminuria/creatininuria de primera micción (mg/g). VFG < 60 ml/min o albuminuria ≥ 30 mg/g, definieron ERCs. Se determinaron frecuencias y comparaciones (chi-cuadrado, t student y Anova), con un nivel de significancia de p < 0,05. Resultados presentaron ERCs 205 sujetos (19,9 %), siendo significativamente más frecuente en ≥ 65 años (35,7 %), quienes alcanzaron estudios básicos (26,6 %), labores de servicio doméstico (44 %), pensionados (40 %), quienes tenían familiares en diálisis (24,6 %) y diabéticos insulino-requirentes (70,6 %). En el grupo ≥ 65 años hubo una significativa menor frecuencia de ERCs en aquellos que realizaban actividad física, comparado con los sedentarios (48,8 %). A mayor intensidad de HTA y presión de pulso (PP) se observó una mayor frecuencia de ERCs. Conclusiones estos datos aportan información epidemiológica útil para la programación de mejores estrategias de detección de ERCs en Chile.
Introduction subclinical chronic kidney disease (CKDs), performing screening in at-risk populations, is poorly characterized in Chile. Its knowledge would contribute to better management and early treatment, mitigating its consequences. Objective to describe the epidemiological and clinical characteristics of the population with CKDs in Chile. Methodology cross-sectional descriptive study in a population of 1,032 subjects from three regions of Chile; Coquimbo (n=902), Metropolitana (n=70) and De Los Ríos (n=60), from cardiovascular programs, other Primary Care programs and direct relatives of dialysis patients. Informed consent, survey, physical examination (blood pressure, weight and height) and laboratory tests (creatinine and albumin/creatinine urinary ratio) were performed. CKD was defined by KDOQI-2012 guideline and Glomerular Filtration Rate according to MDRD formula. Albuminuria by relation albumin/creatinine of first urination (mg/g). eVFG <60 ml/min and/or Albuminuria ≥ 30 mg/g, defined CKDs. Frequencies and comparisons were determined (chi-square, t student and ANOVA), with a significance level of p < 0.05. Results 205 subjects (19.9%) presented CKDs, being significantly more frequent in ≥65 years (35.7%), who achieved elementary school studies (26.6%), domestic service workers (44%), retired workers (40%), having a family member on dialysis (24.6%) and insulin-requesting diabetics (70.6%). In the ≥65 year-old group, there was a significantly lower frequency of CKDs in those who performed physical activity, compared to sedentary (48.8%). The higher the intensity of hypertension and pulse pressure (PP), the higher the frequency of CKDs. Conclusions These data provide useful epidemiological information for the programming of better detection strategies for CKDs in Chile.
RESUMO
Background:Diabetic nephropathy is the most important cause of the end-stage renal disease (ESRD). The aim of the study is to evaluate the effect of spironolactone 25 mg once daily in addition to losartan 50 mg once daily for 12 weeks for proteinuria reduction in diabetic nephropathy. Methods:This is a prospective clinical trial was carried out in the department of nephrology, national institute of kidney diseases and urology (NIKDU), Dhaka, Bangladesh from March 2015 to April 2016. A total of 60 patients attended the study considering inclusion and exclusion criteria. Proper ethical consent was taken from the relevant. Collected data were classified, edited, and analyzed into the computer for statistical analysis using SPSS version 22. Results:The mean serum creatinine baseline, end of 1st, 4th, 8th,and 12thweeks were significantly low (p<0.05) in the control group and significantly decline (p<0.05) in subsequent follow-up in both Intervention and control groups. The mean serum potassium-baseline, end of 1st, 4th, 8th,and 12weeks were not statistically significant (p>0.05) and significantly increased (p<0.05) in both groups. Improvement of urine albumin creatinine ratio was found 96.7% and 83.3% at end of 12thweeks in both groups respectively. It was observed that mean eGFR-baseline, endof 4thand 12thweeks were statistically significantly higher (p<0.05) in both groups with baseline. Conclusions:The addition of spironolactone 25 mg once daily with losartan potassium 50 mg daily for a 12-week period did not show a significant role in the reduction of proteinuria in diabetic nephropathy patients.
