RESUMO
Objective To analyze the influence of medication compliance of chronic type 2 diabetes management patients on disease control in two communities in Kunming.Methods A total of 138 patients with type 2 diabetes who were included in chronic disease management in Guandu and Xiaobanqiao communities of Kunming were selected from December 2021 to September 2022.Basic information collection and HbAlc and other related tests were improved.A questionnaire survey of 8-item Morisliy medication adherence scale(MMAS-8)was conducted to analyze the levels of HbAlc and other indexes of three groups with high(group A),medium(group B),and low(group C)adherence,and to conduct statistical analysis.Results Group A accounted for 22.5%,group B for 44.9%,and group C for 32.6%.There were significance differences in urinary albumin creatinine ratio(UACR),HbA1c and blood creatinine among the three groups(P<0.05).The levels of UACR,HbAlc and serum creatinine in group A were lower than those in group B and group C,and there was a negative correlation between UACR,HbAlc and serum creatinine and medication compliance rate(P<0.05).Conclusion In the Guandu Community and Xiaobanqiao community of Kunming,only 22.5%of patients with chronic type 2 diabetes had high medication compliance.The higher the compliance,the lower the level of UACR,HbAlc and serum creatinine,there is a correlation between the two,suggesting that medication compliance should be regarded as one of the key points in the management of chronic diabetes mellitus in the community,and the intervention of patients'medication compliance should be strengthened.
RESUMO
Objective:To explore the clinical characteristics and risk factors of abnormal urinary albumin/creatinine ratio(UACR) in obese population.Methods:Baseline data from 2011 to 2012 in Henan Sub-center of"Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal(REACTION) study"were utilized and those of body mass index≥28 kg/m 2 were screened. The patients were divided into UACR normal group and UACR abnormal group(101 pairs) upon being matched on a 1∶1 basis by age and gender. Multivariate logistic regression analysis, receiver operating characteristic(ROC) curve, and restricted cubic spline(RCS)analysis were performed to explore the risk factors for abnormal UACR. Results:Compared with the normal UACR group, the UACR abnormal group had a higher number of alcohol consumers, a higher prevalence of hypertension, elevated systolic blood pressure, and triglyceride(all P<0.05). Multivariate logistic regression analysis showed that alcohol consumption( P=0.008), systolic blood pressure( P<0.001), triglyceride( P=0.049), and homeostasis model assessment for insulin resistance(HOMA-IR, P=0.033) were independent risk factors for abnormal UACR in obese people. The ROC curve analysis indicated that systolic blood pressure had the strongest diagnostic performance as a single factor(ROC curve area=0.801), and there was no significant difference in diagnostic performance compared to multiple factors combination. RCS analysis results showed that the probability of abnormal UACR increased monotonically with the increase of systolic blood pressure when the systolic blood pressure was between 130 and 158 mmHg(1 mmHg=0.133 kPa). When systolic blood pressure was not in the interval, the probability of abnormal UACR did not change significantly. The results of regression analysis of triglyceride subgroup showed that when triglyceride level was greater than or equal to 5.6 mmol/L, the risk of abnormal UACR level was significantly increased( P=0.029). Conclusion:Systolic blood pressure, triglyceride, HOMA-IR, and alcohol drinking history are independent risk factors for abnormal UACR in obese people. When systolic blood pressure is≥130 mmHg or triglyceride is≥5.6 mmol/L, the risk of abnormal UACR is significantly increased.
RESUMO
Objective To investigate the cardiac structural and functional characteristics in the patients with heart failure with preserved ejection fraction (HFpEF) and type 2 diabetes mellitus (T2DM),and predict the factors influencing the characteristics. Methods A total of 783 HFpEF patients diagnosed in the Department of Geriatric Cardiology,the First Hospital of Lanzhou University from April 2009 to December 2020 were enrolled in this study.Echocardiography and tissue Doppler technique were employed to evaluate cardiac structure and function.According to the occurrence of T2DM,the patients were assigned into a HFpEF+T2DM group (n=332) and a HFpEF group (n=451).Propensity score matching (PSM)(in a 1∶1 ratio) was adopted to minimize confounding effect.According to urinary albumin excretion rate (UAER),the HFpEF+T2DM group was further divided into three subgroups with UAER<20 μg/min,of 20-200 μg/min,and>200 μg/min,respectively.The comorbidities,symptoms and signs,and cardiac structure and function were compared among the groups to clarify the features of diabetes related HFpEF.Multivariate linear regression was conducted to probe the relationship of systolic blood pressure,blood glucose,glycosylated hemoglobin,and UARE with cardiac structural and functional impairment. Results The HFpEF+T2DM group had higher prevalence of hypertension (P=0.001) and coronary heart disease (P=0.036),younger age (P=0.020),and larger body mass index (P=0.005) than the HFpEF group,with the median diabetic course of 10 (3,17) years.After PSM,the prevalence of hypertension and coronary heart disease,body mass index,and age had no significant differences between the two groups(all P>0.05).In addition,the HFpEF+T2DM group had higher interventricular septal thickness (P=0.015),left ventricular posterior wall thickness (P=0.040),and left ventricular mass (P=0.012) and lower early diastole velocity of mitral annular septum (P=0.030) and lateral wall (P=0.011) than the HFpEF group.Compared with the HFpEF group,the HFpEF+T2DM group showed increased ratio of early diastolic mitral filling velocity to early diastolic mitral annular velocity (E/e') (P=0.036).Glycosylated hemoglobin was correlated with left ventricular mass (P=0.011),and the natural logarithm of UAER with interventricular septal thickness (P=0.004),left ventricular posterior wall thickness (P=0.006),left ventricular mass (P<0.001),and E/e' ratio (P=0.049). Conclusion The patients with both T2DM and HFpEF have thicker left ventricular wall,larger left ventricular mass,more advanced left ventricular remodeling,severer impaired left ventricular diastolic function,and higher left ventricular filling pressure than the HFpEF patients without T2DM.Elevated blood glucose and diabetic microvascular diseases might play a role in the development of the detrimental structural and functional changes of the heart.

Objective:To investigate the value of serum monocyte/high-density lipoprotein cholesterol ratio (MHR) and urinary albumin/creatinine ratio (ACR) in the evaluation of osteoporosis in diabetic nephropathy patients.Methods:Diabetic nephropathy patients treated in Hangzhou Ninth People’s Hospital from Jun. 2019 to Jun. 2022 were selected. Gender, age, height and weight of all patients were collected and recorded, and body mass index (BMI) was calculated. Blood calcium (Ca), blood phosphorus (P), parathyroid hormone (PTH), monocyte count (M), high density lipoprotein (HDL-C), urinary microalbumin and creatinine were measured and recorded in all patients. MHR and ACR were calculated, MHR=M/HDL-C, ACR=urinary microalbumin/creatinine. Lumbar spine bone mineral density (L1-L4) was measured by dual-energy X-ray absorptiometry, which was divided into osteoporosis group and non-osteoporosis group.Results:Among the 117 diabetic nephropathy patients, 47 cases were osteoporotic and 70 cases were non-osteoporotic. The proportion of women in osteoporosis group was significantly higher than that in non-osteoporosis group, and BMI, PTH, MHR, ACR and bone mineral density were significantly higher than those in non-osteoporosis group, with statistical significance (all P<0.05). Multivariate binary Logistic regression analysis showed that female, MHR and ACR were independent risk factors for osteoporosis in diabetic nephropathy patients (all P<0.05). Spearman correlation analysis showed that serum MHR and ACR were negatively correlated with lumbar bone density, with statistical significance ( r=0.524 and 0.497, P=0.004 and 0.009, respectively). ROC curve analysis showed that the area under the curve (AUC) of serum MHR and ACR for evaluating osteoporosis in diabetic nephropathy patients was 0.870 (0.809-0.931) and 0.849 (0.792-0.905), respectively. The AUC of serum MHR combined with ACR for osteoporosis in diabetic nephropathy patients was 0.927 (0.891-0.964) . Conclusion:Serum MHR and ACR can be used as the evaluation indexes of osteoporosis in diabetic nephropathy patients, and their combined efficacy is better.
RESUMO
Objective:To investigate the association between reproductive lifespan duration (RLD) and urinary albumin-creatinine ratio (UACR) in a Chinese postmenopausal population.Methods:This cross-sectional study included 11 055 naturally postmenopausal women from seven regions of China from May to December 2011. RLD was divided into four groups. Propensity score matching was performed to reduce bias, and logistic regressions and stratifications were conducted to investigate the association between RLD and increased UACR (≥30 mg/g). Mediation effect analysis was performed to quantify the effect of RLD on cardiovascular disease (CVD) induced by elevated UACR.Results:There were 2 373 participants with a RLD of 18-31 years, 2 888 participants with a RLD of 32-34 years, 2 472 participants with a RLD of 35-36 years, and 3 322 participants with a RLD of 37-50 years. The shortest RLD (18-31 years) group was characterized with older age ( P<0.001), a higher incidence of CVD ( P=0.025), and the highest level of UACR ( P<0.001). After adjusting for confounders, women with a longer RLD (37-50 years group) exhibited a lower risk of UACR elevation compared with those with the shortest RLD (18-31 years group) ( OR=0.72, 95% CI 0.64-0.82, P<0.001). Every 1-year extension in RLD was linked to a 2% reduction in the risk of UACR elevation ( OR=0.98, 95% CI 0.97-0.99, P<0.001). Stratified analysis revealed a more significant association between RLD and UACR in women who were a normal weight ( P=0.003) or overweight ( P=0.001), in those without CVD history ( P=0.001), and in those with impaired estimated glomerular filtration rate ( P=0.004). The mediation casual analysis showed that 3.0% of proteinuria inducing CVD events was mediated by RLD ( P=0.048). Conclusion:A longer RLD (37-50 years) is associated with a lower UACR in Chinese postmenopausal women.
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.

RESUMO
Objective:To investigate the correlation between serum concentration of vasohibin-1 (VASH-1) and urinary albumin creatinine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM) and diabetic nephropathy.Methods:The clinical data of 196 patients with T2DM from February 2017 to December 2020 were analyzed retrospectively. According to whether diabetic nephropathy (DN) was combined, 33 patients without DN of T2DM were divided into the control group,and 163 patients with DN of T2DM were divided into the case group, and the case group was divided into four groups:normal albuminuria group (groupⅠ, UACR <30 mg/g, 21 cases),microalbuminuria group (groupⅡ, UACR ≥30-≤300 mg/g, 50 cases), clinical albuminuria group (group Ⅲ, UACR>300 mg/g, 43 cases), and clinical albuminuria hypertensive group (groupⅣ, UACR >300 mg/g with hypertension, 49 cases). Serum levels of VASH-1,C-reactive protein(CRP), erythrocyte sedimentation rate (ESR) and transforming growth factor β1 (TGF-β1) with other biochemical indicators were measured. T-test was used for comparison between measurement data groups in accordance with normal distribution, one-way ANOVA was used for comparison between multiple groups, q-test was used for pairwise comparison, and χ2 test was used for comparison between counting data groups. The influencing factors were analyzed by multivariate Logistic regression.Pearson correlation analysis was used to analyze the correlation between vash-1 and UACR. Results:UACR((1 175.9±120.4) mg/g), CRP((9.80±2.01) mg/L), ESR((20.61±2.20) mm/h),TGF-β1((16.75±2.05) μg/L), VASH-1((645.3±183.5) ng/L) in case group were higher than that in the control group((11.5±2.0) mg/g, (4.77±1.34) mg/L, (8.33±1.56) mm/h, (10.63±1.97) μg/L, (416.3±162.1) ng/L), and there were significant differences between the two groups ( t=123.39,13.76,30.54,15.75,6.66; all P<0.001). Multivariate logistic regression analysis showed that VASH-1 ( OR=1.881,95% CI 1.146-3.089), UACR( OR=1.511,95% CI 1.064-2.146), TGF-β1( OR=1.846,95% CI 1.135-3.001)were all risk factors for DN of T2DM ( P values were 0.009, 0.022 and 0.012). Serum VASH-1 ((693.5±201.4), (709.8±214.7) ng/L] in group Ⅲ and group Ⅳ were higher than those in group Ⅰ and group Ⅱ ((585.3±162.1), (632.9±165.5) ng/L). There was significant difference between the two groups ( F=129.46, P<0.001). The CRP ((7.08±1.36), (8.99±3.72), (10.58±3.48), (11.64±3.50) mg/L), ESR ((17.36±1.76), (19.05±4.12), (21.45±5.74), (22.69±9.13) mm/h) and TGF- β1 ((14.75±1.97), (16.50±1.90), (17.06±1.23), (18.39±1.46) μg/L) of groupⅠ, groupⅡ, groupⅢ and groupⅣ increased gradually, and there were significant differences between the four groups ( F values were 73.48, 156.61, 25.83; all P<0.001). Pearson correlation analysis showed that there was a significant positive correlation between VASH-1 and UACR ( r=0.532, P=0.008). Conclusion:The concentration of VASH-1 in serum of patients with T2DM complicated with DN increased with the increase of UACR. VASH-1 may become a new marker for predicting early DN of T2DM.
RESUMO
Objective:To investigate the clinical diagnostic value of joint test of retinol-binding protein (RBP), cystatin C (CYSC) and urinary (albumin/creatinine ratio, ALB/Cr) ALB/Cr in early diabetes nephropathy.Methods:Data of 50 early diabetic nephropathy patients (EDN group) from Jan. 2020 to Jun. 2021 in our hospital, another 50 pure type 2 diabetic patients (T2DM group), and 50 healthy subjects (control group) were compared and analysed. RBP, CYSC and urinary ALB/Cr were tested for the 3 groups. Then the clinical diagnostic value between single index test and joint test for the early diabetes nephropathy were compared.Results:Group EDN had higher RBP, CYSC and urinary ALB/Cr [ (114.66±0.56) mg/L, (2.64±0.33) mg/L, (351.81±15.48) ] mg/g than group T2DM [ (83.58±0.83) mg/L, (1.41±0.29) mg/L, (113.65±12.55) mg/g] and control group[ (38.61±0.66) mg/L, (0.53±0.26) mg/L, (16.36±5.61) mg/g]. The difference was statistically significant ( P<0.05). The specificity and sensitivity of early diabetes nephropathy were 95.38% and 96.21%, both higher than single index test. Conclusion:The combined detection of serum RBP, CYSC and urine ALB/Cr has certain reference value for the clinical diagnosis of early diabetic nephropathy.
RESUMO
Objective:Using 24-hour urinary sodium excretion (24h-UNa) as the surrogate measure of sodium intake, to evaluate the joint association of 24h-UNa and serum 25-hydroxy vitamin D (25-OHD) levels with the risk of albuminuria in patients with type 2 diabetes mellitus (T2DM).Methods:This retrospective study included 670 hospitalized T2DM cases in the Department of Endocrinology and Metabolic Diseases, the First Affiliated Hospital of Zhengzhou University from January 2018 to October 2021. Patients were divided into the albuminuria-positive group or negative-group according to the level of 24-hour urinary albumin excretion (24h-UAE); They were also divided into the high-sodium group or low-sodium group according to the level of 24h-UNa; Patients were divided into the low-VD group or high-VD group according to the level of 25-OHD. Combining 24h-UNa and 25-OHD, the patients were further divided into four groups: high-VD low-sodium group ( n=85), high-VD high-sodium group ( n=122), low-VD low-sodium group ( n=248), and low-VD high-sodium group ( n=215). The effect of 24h-UNa and 25-OHD association on albuminuria was analyzed by binary regression. Results:There were significant differences in 24h-UAE level among the four groups ( P<0.01), the level of 24h-UAE in the low-VD high-sodium group was significantly higher than that in low-VD low-sodium group, high-VD low-sodium group, and high-VD high-sodium group [39.00(13.00, 319.00)mg/24 h vs 22.00(10.00, 99.00)mg/24 h, 22.00(9.00, 72.50)mg/24 h, 22.45(9.69, 72.75)mg/24 h; P=0.047, P=0.019, P=0.030]. Correlation analysis showed a positive correlation between 24h-UNa and 24h-UAE in the low-VD group ( P=0.017), but not in the high-VD group ( P=0.411). Binary regression analyses showed that both 24h-UNa ( P=0.017) and 25-OHD( P=0.023) were independent risk factors for positive albuminuria in patients with T2DM. The risk of positive albuminuria in the low-VD high-sodium group was 1.789 times higher than that in the high-VD low-sodium group ( P=0.037). Conclusion:24h-UAE in T2DM patients was affected by the combination of 24h-UNa and 25-OHD. A low level of 25-OHD increased the risk of albuminuria in high sodium intake T2DM patients.
RESUMO
Objective:To evaluate the effect of urinary albumin creatinine ratio (UACR) on diabetic retinopathy (DR) in patients with type 2 diabetes. Receiver operating characteristic (ROC) curve was applied to find the cut-off value of UACR for diagnosing DR.Methods:A prospective cohort study of 2 490 patients with type 2 diabetes was conducted with a mean follow-up of 7 years ranging from 3 to 10 years. Dilated fundus examination was performed once a year, and patient history and clinical data were collected and analyzed. Patients were divided into three groups according to the UACR: Q1, normal urinary albumin group (UACR<30 mg/g), Q2, microalbuminuria group (30 mg/g≤UACR≤299 mg/g), and Q3, macroalbuminuria group (UACR>300 mg/g), respectively. Cox regression analysis was used to explore the influence of UACR and other factors on DR, and ROC curve was drawn to evaluate the value of UACR in diagnosis of DR.Results:Cox regression analysis showed that UACR was the risk factor of DR( HR=1.108, 95% CI 1.023-1.241, P<0.001). It showed that the patients in Q3 group had the highest risk of proliferative DR ( HR=3.128, 95% CI 2.025-4.831, P<0.001), the patients in Q2 group followed( HR=1.918, 95% CI 1.355-2.714, P<0.001), and the patients in Q1 group were the lowest. ROC curve analysis showed that area under UACR curve was 0.746(95% CI 0.681-0.812, P<0.001), and the cut-off value, sensitivity, and specificity for the diagnosis of PDR were 54.12mg/g, 0.769, and 0.653, respectively. Conclusion:The UACR can predict the progression of PDR in type 2 diabetes patients, therefore it may be used as a preliminary predictor for the progression of DR.
RESUMO
Objective:To investigate the correlation between early renal impairment markers in urine and elevated serum homocysteine.Methods:Clinical data of serum homocysteine (Hcy) and early renal injury markers in urine of the health examination population from the Physical Examination Center of Peking University Third Hospital from January 2019 to May 2020 were retrospectively analyzed (1133 cases). The previous medical history, age, sex, blood pressure, body mass index (BMI) of the subjects were collected. Early urine kidney injury markers, including urine microalbumin (U-mALB), urinary N-acetyl-β-D-glucosaminidase (NAG), urinary albumin to creatinine ratio (UACR), and serum renal function, liver function, blood lipid, myocardial enzyme and glycosylated hemoglobin (HbA 1C), etc. were also collected. Those with incomplete previous history, general information, biochemical indexes and decreased estimated glomerular filtration rate (eGFR) were excluded, and 969 cases were included. The included subjects were divided into the normal group (?15 μmol/L) and the elevated group (≥15 μmol/L) according to Hcy levels, the indexes with significant difference between the two groups were included as independent variables, and the multivariate logistic regression was used to explore the influence factors of Hcy elevation. Results:The male ratio, the incidence of increased U-mALB, NAG and UACR were significantly higher in the elevated group than those in the normal Hcy group (93.4% vs 50.6%, 16.4% vs 8.0%, 23.0% vs 14.0%, 13.9% vs 7.9%) (all P<0.05). Systolic blood pressure, diastolic blood pressure, serum uric acid, calcium, alanine aminotransferase (ALT) and lactate dehydrogenase in the elevated group were higher than those in the normal group [(127.5±15.4) vs (121.9±16.2) mmHg (1 mmHg=0.133 kPa), (78.6±9.3) vs (76.0±11.0) mmHg, (385.9±86.0) vs (335.7±88.2) μmol/L, (2.392±0.086) vs (2.366±0.092) mmol/L, (27.8±21.0) vs (23.8±20.2) U/L, (198.3±28.4) vs (192.2±31.2) U/L] (all P<0.05), while high density lipoprotein cholesterol (HDL-C), serum phosphorus were lower than those in the normal group [(1.21±0.25) vs (1.31±0.30) mmol/L, (1.107±0.154) vs (1.158±0.159) mmol/L] (all P<0.05). The increased systolic blood pressure, male, uric acid, U-mALB, NAG were independent correlative factors of Hcy elevation. Conclusion:The increase of Hcy is independently correlated with urine U-mALB and NAG, which suggests that the level of Hcy should be detected as soon as possible in patients with elevated early renal injury markers.
RESUMO
Background: Urinary albumin excretion has been purported to be strongly linked to cardiovascular events in hypertensive patients. The prevalence of microalbuminuria in patients with essential hypertension and its relationship with target organ damage was evaluated with the present study, as the correlation of microalbuminuria and target organ damage except cardiovascular events has not been deliberated upon much in the past.Methods: One hundred and twenty cases of essential hypertension were enrolled sequentially. Prevalence of urinary albumin excretion and its correlation with target organ damage (left ventricular hypertrophy, retinopathy and stroke) was analyzed. Urinary albumin excretion was assessed by turbidimetry method, while microalbuminuria was calculated by urine albumin to creatinine ratio.Results: Microalbuminuria was observed in 57.7% cases of essential hypertension. Target organ damage was observed in 62.5% (75) patients, out of which 78.66% patients had associated microalbuminuria (p<0.05). Higher prevalence was observed in patients with longer duration and greater severity of hypertension, increased body mass index and dyslipidemia.Conclusions: The assessment of microalbuminuria in hypertensive patients is a great value addition for the evaluation of target organ damage. Prompt control of hypertension and lipid levels along with weight management may lead to decreased risk of microalbuminuria.
RESUMO
Background: Preeclampsia is a multisystem endothelial disease leading to glomeruloendotheliosis with endothelial leak causing significant proteinuria. It is associated with high maternal and fetal risks and fetomaternal morbidity and mortality. Spot urinary albumin to creatinine ratio (ACR) leads to earlier detection of glomerular damage leading to prompt management of preeclamptic patients. To determine the accuracy of Spot Urinary ACR as an indicator to detect proteinuria and its use as a rapid alternative test over 24-hour urinary protein in women with Preeclampsia and to find the correlation between the two.Methods: Spot urinary ACR was measured in 70 consecutive patients with preeclampsia in Assam Medical College, Dibrugarh. The best cut-off value to differentiate between significant and insignificant proteinuria was calculated. The mean, standard deviation and range of various parameters were computed and various statistical tests were used. The Area under the curve and ROC curve were plotted.Results: The best cut-off value to differentiate significant and insignificant proteinuria was calculated as 291.9 mg/g beyond which adverse fetomaternal outcomes and complications were seen. The correlation coefficient between 24-hour urinary protein and spot urinary albumin to creatinine ratio was 0.922 highly significant. The area under the curve was found to be 0.98 with a standard error of 0.0155 which implied that the discriminant ability of spot urinary ACR to differentiate significant proteinuria from insignificant proteinuria in patients with preeclampsia was found to be 98%. Similar studies mentioned in the table below showed a good correlation between 24-hour urinary protein estimation and spot urinary ACR.Conclusions: Compared with 24-hour urinary protein excretion, spot urinary ACR is a simple and accurate indicator of significant proteinuria and helps to detect fetomaternal outcomes in preeclamptic women which may lead to prompt management to reduce fetomaternal complications.
RESUMO
Background: Sepsis following surgery or trauma remains one of the leading causes of morbidity and mortality in hospitalpopulations, especially in populations in intensive care units (ICUs). The key to successful control of sepsis-associated infectionsis early prediction and rapid treatment of the disease. Standard clinical and laboratory parameter testing estimate the levels ofexpression of interleukin-1 β (IL-1 β), IL-6, IL-8, and IL-10, tumor necrosis factor-α, FasL (Fas ligand is a type-II transmembraneprotein), and CCL2 (C-C Motif Chemokines Ligand 2) mRNA and growth differentiation factor-15. These are a few measuredby real- time reverse transcriptase polymerase chain reaction.Aim of the Study: In this study, evaluation of the urinary albumin/creatinine ratio (ACR) was used as a prognostic predictorin critically ill sepsis patients.Materials and Methods: In a prospective observational study, 365 adult critically septic patients were included. After clinicalevaluation, urine spot samples were collected on admission and 24 h later for ACR1 and ACR2. Admission Acute Physiologyand Chronic Health Evaluation (APACHE) IV score and the highest recorded Sepsis-related Organ Failure Assessment (SOFA)score of their daily estimation were considered. The need for mechanical ventilation was assessed in addition to inotropic and/or vasoactive support, renal replacement therapy (RRT), and in-hospital mortality.Observations and Results: A total of 365 patients who were critically ill with sepsis were initially recruited to this study. Thepatients included in this study were aged between 28 and 87 with a mean age of 62.37 ± 9.15 years. There were 235 (64.38%)males and 130 females (35.61%). The highest SOFA score was 7.4 (4.0–14.0) ranging from 1 to 17 and APACHE IV scorerecorded within the first 24 h of ICU admission was 76.8 (58.8–98.0) ranging from 46 to 118. Of 365 patients, 191 (52.32%)required ventilator support, 201 (55.06%) needed inotropic and/or vasoactive support to maintain hemodynamics, and 71(19.45%) needed RRT. The mean length of hospital stay in the present study was 17.65 ± 8.60 days.Conclusions: Evaluating the urinary ACR values regularly in all critically ill sepsis patients was a simple, rapid, non-invasive,inexpensive, easy to perform, and interpret test for early prognosis and prediction of mortality
RESUMO
Background: Primary hypothyroidism is a clinical conditiondue to deficiency of thyroid hormones. Thyroid hormones haveprofound effect on renal development, renal hemodynamics,glomerular filtration rate, electrolytes and water homeostasis.The aim of this case control prospective study is to evaluatethe effect of primary hypothyroidism on renal functions.Methods: Serum creatinine, blood urea nitrogen, uric acid,urinary albumin creatinine ratio and eGFR levels wereestimated in 75 newly diagnosed and untreated patients ofprimary hypothyroidism in the age group of 20 to 60 years ofeither sex (Study group) and 75 healthy, age and sex matchedindividuals with normal thyroid profile (Control group). Followup of patients in study group was done after 8 weeks ofthyroxine replacement and serum creatinine, uric acid, urinaryalbumin creatinine ratio and eGFR levels were estimated.Results: The mean eGFR level in study group at baseline waslower and mean serum creatinine, blood urea nitrogen, serumuric acid and urinary albumin creatinine ratio (UACR) levelswere higher than control group. After 8 weeks of thyroxinereplacement; the mean serum creatinine, uric acid, bloodurea nitrogen levels were decreased and eGFR levels wereincreased. Also serum TSH shows positive correlation withserum creatinine, blood urea nitrogen, uric acid and urinaryalbumin creatinine ratio but negative correlation with eGFR.Conclusion: Primary hypothyroidism is associated withsignificant alteration in renal function which is reversible onthyroxine replacement.
RESUMO
Introduction: Diabetic kidney disease (DKD) representsone of the most frequent microvascular complications ofdiabetes with an overall prevalence of approximately 40% intype 2 diabetes population. Microalbuminuria is one of themost serious problems in type 2 DM. Vildagliptin, DPP-4inhibitors, is a novel oral anti-diabetic drug for the treatmentof type 2 diabetes mellitus (T2DM). The objective of the studywas to evaluate the therapeautic efficacy of vildagliptin onmicroalbuminuria in type 2 diabetes mellitus.Material and methods: We included in our study 103 T2DMpatients with microalbuminuria. Exclusion criteria: NSAIDsinduced nephropathy, Lupus nephropathy, Polycystic KidneyDisease, Medullary Sponge Kidney, All causes of nephriticand nephrotic syndrome, ESRD due to diabetes mellitus andmoderate to severe hepatic failure. We measured UrinaryACR value of parameters at 0,3.6,9,12 months respectively.Vildagliptin was given to those patient and was observed thatafter giving vildagliptin was there any change in albumin tocreatinine i.e microalbuminuria.Result: The mean of ACR baseline (mean±s.d.) of patientswas 125.1436 ± 58.810 with range 50.7000 - 298.0000 and themedian was 100.0000. The mean of ACR of 3, 6, 9, 12months(mean±s.d.) of patients were 110.3184 ± 57.5647, 106.7340 ±48.8492, 103.7252 ± 45.6745, 95.4466 ± 62.342 respectively.Association of ACR in five groups was not statisticallysignificant (p=0.6118).Conclusion: We found that after 12 months of therapy withvildagliptin, a DPP-4 inhibitor, there was some reduction ofACR and it is approximately 30%

Objective To observe the effect of the method of warming kidney and dredging collaterals on the clinical effect and the content of urine C5b-9 in patients with idiopathic membranous nephropathy with spleen kidney yang deficiency and blood stasis. Methods A total of 60 idiopathic membranous nephropathy patients with spleen kidney yang deficiency and blood stasis type were randomly divided into the conventional western medicine treatment group (control group), Jingui-Shenqi pill and Taohong-Siwu decoction plus conventional western medicine treatment group (treatment group), 30 cases in each group. The Scr was detected by deproteinized alkaline picric acid method, and BUN was detected by rate method, and serum albumin (ALb) was detected by bromocresol green dye binding method, and 24 hours urinary protein was measured by pyrogallol red colorimetry, and the double antibody sandwich ELISA method was used for detection of urinary C5b-9. Results The Jingui-Shenqi pill combined with Taohong-Siwu decoction plus conventional western medicine treatment has obvious curative effect on patients. The total effective rate was 83.3 in the treatment group (25/30), and the control group was 60％ (18/30). After treatment, the Alb (33.5 ± 7.95 g/L vs. 28.8 ± 6.10 g/L, t=2.569) in the treatment groupwas significantly higher than that in the conventional treatment group (P<0.01). While the 24 h urine protein (2.40 ± 0.92 g/24 h vs.3.60 ± 2.3 g/24 h, t=2.653), the contents of C5b-9 in urine(42.5 ± 17.50 ng/mg vs.71 ± 25.2 ng/mg, t=5.088) in the treatment group were significantly lower than those in the conventional treatment group (P<0.01). Conclusions The method of warming kidney and dredging collaterals can improve the clinical symptoms, improve serum albumin level, reduce the 24 hour urine protein and urinary C5b-9 content of idiopathic membranous nephropathy of spleen and kidney yang deficiency and blood stasis type.
RESUMO
Objective To investigate the expression and clinical significance of vasohibin-1 (VASH-1) in patients with type 2 diabetes mellitus.Methods From November 2015 to December 2017,four hundred and twenty-two patients with T2DM in Chaoyang Central Hospital were selected and divided into three groups according to the urinary albumin excretion rate (UACR):normal albuminuria group (UACR ＜30 mg/g,149 cases),microalbuminuria group (30 ≤ UACR ≤ 300 mg/g,143 cases),clinical albuminuria group(UACR＞300 mg/g,130 cases).Three hundred healthy subjects in Chaoyang Central Hospital during the same period were selected as control group.The levels of serum VASH-1 and transforming growth factor-β1 (TGF-β1) in each group were determined by enzyme linked immunosorbent assay.Results VASH-1 and TGF-β1 in diabetic group and control group were (579±236) ng/L,(350±141) ng/L and (18.92 ±2.21) μg/L,(5.69 ± 0.70) μg/L,respectively.There were significant differences between the two groups (t =4.721,6.142,P＜0.01).The serum VASH-1 levels in normal albuminuria group,microalbuminuria group and massive albuminuria group were (450+182) ng/L,(571±194) ng/L,(786±201) ng/L,and the serum TGF-β1 levels were (11.71 ± 1.81) μg/L,(14.02 ± 2.91) μg/L,(19.32 ± 1.97) μg/L,respectively.Compared with the normal albuminuria group,the serum VASH-1 and TGF-β1 levels in the microalbuminuria group and the massive albuminuria group were significantly higher (P＜0.05),and the serum VASH-1 and TGF-β1 levels in the massive albuminuria group were significantly higher than those in the microalbuminuria group,with significant difference between the two groups (P＜0.05).Multivariate linear regression analysis showed that serum VASH-1 level was positively correlated with TGF-β1 in diabetic patients (r=0.554,P=0.000).Conclusion With the progress of DN microangiopathy,the serum VASH-1 concentration in type 2 diabetes mellitus increased significantly through negative feedback to regulate and control the formation of neovascularization and delay renal interstitial fibrosis,so as to achieve the protection of the kidney.
RESUMO
Objective To investigate the effect of alogliptin on albuminuria in patients with early type 2 diabetic kidney disease (DKD) and the related mechanism.Methods One hundred patients with early DKD admitted in our hospital from May 2016 to May 2017 were randomly divided into two groups with 50 cases in each group.Patients in the control group were given metformin and gliclazide,while those in study group were given metformin and alogliptin,the treatment lasted for 24 weeks.The changes of urinary albumin-to-creatinine ratio (UACR),stromal cell-derived factor-1α (SDF-1α) and the fasting plasma glucose (FPG),2-h postprandial plasma glucose (2 hPPG),glycosylated hemoglobin(HbA1c) were measured before and after the treatment in two groups.Results There were no significant differences in HbA1c [(8.17± 0.46)％ vs.(8.29±0.48)％],UACR[(109±53) vs.(105±48)mg/g],SDF-1α [(1.21±0.3 9) vs.(1.17±0.35)μg/L] levels before treatment between two groups (t=0.343,0.464,0.075,all P＞0.05).After treatment,the HbA1c levels were significantly decreased in both groups (t=2.293,2.302,all P=0.03) and there was no significant difference between two groups[(6.82±0.75)％ vs.(6.93 ±0.79)％,t=0.295,P=0.77];the UACR levels were significantly reduced in both groups,but the level of study group was significantly lower than that of control group [(82±38) vs.(94±47) mg/g,t=3.320,P＜0.01];the SDF-1α levels were significantly increased in both groups,but the level of study group was significantly higher than that of control group[(3.01 ±0.38) vs.(2.76±0.42)μg/L,t=5.474,P＜0.01].There was no significant difference in the incidence of adverse reactions between the two groups [13％ (6/46) vs.12％ (6/48),x2=0.002,P＞0.05].Conclusion Alogliptin can effectively control the blood glucose,reduce urine albumin excretion and protect renal function in patients with early type 2 diabetic nephropathy,which is associated with the increased SDF-1α levels.
