ABSTRACT

It is known that the combined use of antibiotics, such as isoniazid and rifampicin, in the treatment of tuberculosis causes oxidative kidney damage. The aim of this study was to biochemically and histopathologically investigate the effect of lycopene on oxidative kidney damage due to the administration of isoniazid and rifampicin in albino Wistar male rats. Lycopene at a dose of 5 mg/kg was orally administered to lycopene+isoniazid+rifampicin (LIR) rats, and normal sunflower oil (0.5 mL) was orally administered to isoniazid+rifampicin (IR) and healthy control (HG) rats as vehicle by gavage. One hour after the administration of lycopene and vehicle, 50 mg/kg isoniazid and rifampicin were given orally to the LIR and IR groups. This procedure was performed once a day for 28 days. Rats were sacrificed by a high dose of anesthesia at the end of this period, and oxidant-antioxidant parameters were measured in the removed kidney tissues. Creatinine and blood urea nitrogen (BUN) levels were measured in blood samples, and kidney tissues were also evaluated histopathologically. The combined administration of isoniazid and rifampicin changed the oxidant-antioxidant balance in favor of oxidants, and it increased blood urea nitrogen and creatinine levels, which are indicators of kidney function. Co-administration of isoniazid and rifampicin also caused oxidative kidney damage. Lycopene biochemically and histopathologically decreased oxidative kidney damage induced by isoniazid and rifampicin administration. These results suggested that lycopene may be beneficial in the treatment of nephrotoxicity due to isoniazid and rifampicin administration.

ABSTRACT

RESUMEN Introducción: El daño renal agudo es una complicación frecuente en las Unidades de Terapia Intensiva, sobre todo en pacientes con ventilación mecánica. Objetivo: Caracterizar el daño renal agudo en los pacientes tratados con ventilación mecánica invasiva en la Unidad de Terapia Intensiva del Hospital General Docente "Dr. Agostinho Neto" durante el periodo 2108-2019. Método: Se realizó un estudio descriptivo, retrospectivo y longitudinal, que se aprobó por el Comité de Ética. El universo de estudio se constituyó por el total de pacientes con este diagnóstico según la clasificación Acute Kidney Injury Network (AKIN). Se estudiaron las características de los pacientes (necesidad y duración de la VAM, necesidad de hemodiálisis, estado al egreso) y del daño renal agudo (estadio y etiología). Resultados: El 47,5 % de los pacientes tratados con este soporte vital presentó un daño renal agudo, sobre todo los que la demandaron por siete o más días (68,4 %). El riesgo de muerte fue superior en los pacientes que requirieron ventilación mecánica o hemodiálisis. En los pacientes con daño renal estadio 2 y 3 de la clasificación que se utilizó presentaron un riesgo tres veces o más superior comparado con los que no necesitaron estas terapias. La sepsis (69,4 %) fue la principal causa del daño renal agudo. Conclusiones: El uso de ventilación mecánica invasiva y la presentación de un daño renal agudo son condiciones con una fuerte asociación, juntas y separadas se correlacionan con la mortalidad.


ABSTRACT Introduction: Acute kidney injury is a very common complication in the intensive care units, especially in patients with invasive mechanical ventilation. Objective: To characterize acute kidney damage in patients with invasive mechanical ventilation in the intensive care unit at the General Teaching Hospital ¨Dr. Agostinho Neto¨ within the period 2018-2019. Method: A descriptive, retrospective and longitudinal study approved by the Ethics Committee was carried out. The study population was constituted by the total of patients with the diagnosis, according to the Acute Kidney Injury Network (AKIN). Characteristics and variables like: reason for the invasive mechanical ventilation, its duration, hemodialysis, and status of the patient at time of discharge were taken into account, along with the characteristics of the kidney injury (stages and etiology). Results: 47.5 % of the patients treated with life support showed acute kidney injury, especially the ones with more than a week of mechanical ventilation (68.4 %). The risk of death was higher in the patients with mechanical ventilation and hemodialysis. In the patients with stage 2 and 3 of the scale used for kidney injury presented 3 times more risk compared to those who did not require these treatments. Sepsis was the main cause of acute kidney injury (69.4 %). Conclusions: the use of invasive mechanical ventilation and acute kidney injury are deeply related to each other, both of them constitute main issues in the variables of mortality.

ABSTRACT

Diabetes was investigated as a risk factor for nephrotoxicity induced by vancomycin. In the present study, the drug's nephrotoxic effect was indirectly evaluated by Glomerular Filtration Rate, albuminuria and serum levels of creatinine and urea on the 1st, 7th and 14th days of vancomicyn therapy in a group of diabetic and non-diabetic patients, with and without previous nephropathy. The correlations between investigated variables (including the population's epidemiological profile and hospital care) were measured by the Spearman test. The sample consisted of 132 patients, predominantly male diabetic patients with previous nephropathy, over 40 years, receiving ≥ 10 grams of vancomycin for the treatment of infectious diseases and showing satisfactory clinical outcomes. A risk of vancomycin drug interaction with potential nephrotoxic outcome was observed in 36.4% of patients who used multiple drugs. Furthermore, 80% of patients had an increase of at least 0.5 mg.dL-1 in baseline serum levels of creatinine and urea at the end of the study. This was more common among the diabetic patients with previous nephropathy, showing higher albuminuria and a reduction in the Glomerular Filtration Rate. Therefore, it has been recommended that the use of vancomycin in diabetic patients should be in careful dosages and that kidney functioning be monitored.

ABSTRACT

This study aims to establish a quantitative method of 4 aristolochic acids-DNA adducts in mice kidney and liver based on high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) for monitoring the content changes of aristolochic acids-DNA adducts. A Shiseido Capcellpak AQ C_(18) column(3 mm×100 mm, 3 μm) was used, with a mixture of 0.2% acetic acid-5 mmol·L~(-1) ammonium acetate as the aqueous phase and methanol as the organic phase for gradient elution. The multiple reaction monitoring(MRM) scanning method under positive mode by electrospray ionization(ESI) was performed for the detection of the aristolochic acids-DNA adducts which formed by combining aristolochic acid Ⅰ/Ⅱ with deoxyadenosine, deoxyguanosine, and deoxycytidine, respectively. Balb/c mice were given Guanmutong extract by gavage, and the relative content of aristolochic acids-DNA adducts in liver and kidney samples were analyzed within 60 days. It was found that the concentration of 4 aristolochic acids-DNA adducts in the kidney was significantly higher than that in the liver, and there were about 15.87 adducts in per 1×10~6 normal deoxynucleosides, which was 4.5-7.5 times than that of the liver. What's more, some adducts can still be detected on the 30 th day after administration. The concentration of the adducts in the liver was highest on the first day after administration, and a second peak appeared during the 7 th to 14 th days. The results indicated that aristolochic acids-DNA adducts are difficult to eliminate in vivo, and it is of great significance to study the mechanism of liver and kidney injury of aristolochic acid.

ABSTRACT

Background: Garcinia kola seeds have been observed to be medically important and kolaviron, a bioflavonoid obtained from the seeds was studied for its biological activities. The study investigated the protective effect of kolaviron extract obtained from the seed of Garcinia kola against isoniazid-induced kidney damage. Methodology: Kolaviron was extracted from fresh seeds of Garcinia kola (2 kg) using soxhlet extractor and partitioned with chloroform. Nephrotoxicity was induced in wistar rats by oral administration of isoniazid (20 mg/kg bwt) while kolaviron was administered on wistar rats an hour before isoniazid administration and lasted for 30 days. Protective effect of kolaviron was measured in the plasma of wistar rats by estimating the levels of key metabolites used as kidney biomarkers which are total protein, creatinine, urea and uric acid concentration. Results: The isoniazid-treated group showed a significant (p < 0.05) decrease in total protein concentration of 3.57 ± 0.12 (mg/dl) while there was a significant (p < 0.05) increase in urea, uric acid and creatinine concentrations with values of 70.30 ± 4.77, 55.71 ± 11.15 and 18.04 ± 5.33 (mg/dl) respectively. However, kolaviron-treated group showed a remarkable increase (6.15 ± 0.96) in total protein concentration while urea, uric acid and creatinine concentrations significantly decreased to 45.25 ± 2.29, 35.60 ± 11.01 and 13.28 ± 4.41 (mg/dl) respectively. Conclusion: Kolaviron extract obtained from Garcinia kola seeds exhibited a remarkable protective effect against kidney damage caused by isoniazid by regulating renal biomarkers and preventing toxic affront of isoniazid. Thus, it may be relatively safe when used therapeutically at this dose in the treatment and management of diseases associated with kidney damage.

ABSTRACT

Objective More and more research shows microangiopathy may occur in the early stage of diabetes. The purpose of this study was to observe the relationship between OGTT 1-hour hyperglycemia (1hPG) and 2-hour hyperglycemia (2hPG) levels and urinary albumin creatinine ratio (UACR).Methods We retrospectively analyzed 408 patients with primary hypertension of grade 2 or above who were eligible for 2015 World Health Organization (WHO) outpatient and inpatient visits from September 2015 to April 2018 in our hospital for a course of up to 10 years. All selected participants underwent an OGTT test (1 and 2 hour post-sugar glucose) and records were made on fasting plasma glucose (FPG), OGTT1-hour blood glucose (1 hPG), OGTT 2-hour blood glucose (2 hPG). All the patients were divided into 4 groups according to blood glucose levels: NGT group (n=100), 1 h PG group(n=102), 2h PG group(n=104), 1h PG/2h PG group (n=102). Records were made on the clinical data of 408 patients, including height, weight, BMI, gender, age, history of hypertension, smoking history, blood pressure, blood lipids, creatinine and other general clinical data, and the calculation of glomerular filtration rate (eGFR) values was based on creatinine values and age values to analyze the relationship between 1 hHPG and 2 hHPG levels with ACR.Results No significant difference was found among the four groups in the aspects of hypertension course, age, gender, body mass index (BMI), diastolic blood pressure, lipid metabolism index and fasting blood glucose(P>0.05). There were significant difference in systolic blood pressure, serumcreatinine, eGFR, and ACR among different levels of increased blood glucose(P<0.05). ACR in 1h PG group, 2h PG group and 1h PG/2h PG group were significantly higher than NGT group(P<0.01), ACR in 1h HPG/2hHPG was significantly higher than 1h PG group(P<0.05) and ACR in 1h PG group was significantly higher than 2h HPG group(P<0.05). The logistic regression analysis showed that 1h PG(OR=2.461, 95%CI:1.947-3.112), creatinine (OR=1.071, 95%CI:1.027-1.117) and 2h PG(OR=2.016, 95%CI:1.500-2.710) were risk factors for microalbuminuria(P<0.01).Conclusion The abnormalities of 1h PG and 2h PG are associated with ACR, which may become the key index for predicting early kidney damage.

ABSTRACT

<p><b>Background</b>Previous studies have shown that hypertension is an important factor contributing to the occurrence and progression of diabetic kidney damage. However, the relationship between the patterns of blood pressure (BP) trajectory and kidney damage in the diabetic population remains unclear. This prospective study investigated the effect of long-term systolic BP (SBP) trajectory on kidney damage in the diabetic population based on an 8-year follow-up community-based cohort.</p><p><b>Methods</b>This study included 4556 diabetic participants among 101,510 participants. BP, estimated glomerular filtration rate (eGFR), and urinary protein were measured every 2 years from 2006 to 2014. SBP trajectory was identified by the censored normal modeling. Five discrete SBP trajectories were identified according to SBP range and the changing pattern over time. Kidney damage was evaluated through eGFR and urinary protein value. A multivariate logistic regression model was used to analyze the influence of different SBP trajectory groups on kidney damage.</p><p><b>Results</b>We identified five discrete SBP trajectories: low-stable group (n = 864), moderate-stable group (n = 1980), moderate increasing group (n = 609), elevated decreasing group, (n = 679), and elevated stable group (n = 424). The detection rate of kidney damage in the low-stable group (SBP: 118-124 mmHg) was the lowest among the five groups. The detection rate of each kidney damage index was higher in the elevated stable group (SBP: 159-172 mmHg) compared with the low-stable group. For details, the gap was 4.14 (11.6% vs. 2.8%) in eGFR <60 ml·min·1.73 m and 3.66 (17.2% vs. 4.7%), 3.38 (25.0% vs. 7.4%), and 1.8 (10.6% vs. 5.9%) times in positive urinary protein, eGFR <60 ml·min·1.73 m and/or positive urinary protein, and eGFR decline ≥30%, respectively (P < 0.01).</p><p><b>Conclusion</b>An elevated stable SBP trajectory is an independent risk factor for kidney damage in the diabetic population.</p>

ABSTRACT

Objective To explore the protective effect of emodin on kidney damage in high-fat diet-induced obese mice. Methods Male C57bl/ 6 mice were divided into groups according to diet and treatment. Collagen Ⅳ(Col4), phosphatidylinositide 3-kinase(PI3K), phosphorylated phosphoinositol 3-kinase(p-PI3K), protein kinase (Akt), and phosphorylated protein kinase(p-Akt) were measured by Western blotting method. Results Col4 was increased, while p-PI3K and p-Akt were decreased in kidney tissue in high-fat diet-induced obese mice. However, there was lower level of Col4, but higher levels of p-PI3K and p-Akt in kidneys. Conclusion Kidney damage of high-fat diet-induced obese mice seems to be alleviated by emodin via improving insulin sensitivity.

ABSTRACT

OBJECTIVE To investigate the protective effect of total saponins from stems and leaves of Panax ginseng (GSLS) on cisplatin (CDDP)-induced kidney damage in mice and its possible mechanism. METHODS Thirty-two male ICR mice were randomly divided into normal control group, CDDP group, and GSLS(150 and 300)+CDDP groups. GSLS was administered to mice by oral gavage once a day for 7 d. On the 7th day, a single injection of CDDP 20 mg·kg-1 was given 1 h after GSLS 150 and 300 mg·kg-1 before GSLS 150 and 300 mg·kg-1 continued to be given for 3 d. Blood urea nitrogen (BUN) and creatinine (CRE) , catalase (CAT) in renal tissue, reduced glutathione (GSH), tumor necrosis factorα(TNF-α) and interleukin 1β(IL-1β) of cisplatin induced mice were detected after 72 h. HE and PAS staining were used to observe the renal histopathological changes;While TUNEL and Hoechst33258 staining were employed to observe apoptosis in kidney tissues. RESULTS Compared with normal control group, CDDP group had a significant reduction in relative body mass (P<0.05), and the level of GSH and CAT in kidney tissues (P<0.05). The level of CRE, BUN, TNF-α, and IL-1βin serum and renal indexes significantly increased (P<0.05, P<0.01), especially BUN and CRE that respectively doubled and quadrupled. CDDP group developed glomerulus swelling, renal tubular expansion and epithelial cell necrosis. Trans?parent tube type of tube cavity appeared, the nucleus pycnosis disappeared, but renal interstitial edema and inflammatory cell infiltration appeared. There was a large amount of glycogen deposition and high expressions of TUNEL positive cells and Hoechst33258 positive cells. Compared with CDDP group, the levels of BUN and CRE in GSLS treatment group significantly decreased (P<0.05, P<0.01) in serum, glycogen deposition was reducted and apoptosis of renal tubular epithelial cells decreased in kidney tissues (P<0.05). The level of TNF-α, IL-1β(P<0.05) and the degree of renal tissue necrosis were significantly reduced (P<0.05) in CDDP+GSLS 300 group, but there was a significant increase in the level of CAT and GSH (P<0.05). CONCLUSION GSLS can protect against mouse kidney injury induced by cisplatin. The mechanism may be related to oxidation, reduced inflammation reaction and resistance to apoptosis.

ABSTRACT

INTRODUCCIÓN: Las etapas iniciales de la Enfermedad Renal Crónica (ERC) son asintomáticas y los pacientes pueden ignorar su condición o descubrirlo en una consulta de rutina o por otra patología. Dada esta característica y la alta prevalencia mundial aceptada de ERC es necesario disponer de datos confiables para aportar evidencia al conocimiento sobre la enfermedad en la región, atendiendo a la condición de cronicidad. MATERIAL Y MÉTODOS: Estudio descriptivo en 81 estudiantes. Período mayo 2014-diciembre 2015. Se estimó Tasa de Filtrado Glomerular (TFG) por CKD-EPI y clearance de creatinina. Para establecer daño renal se realizó orina completa en primera micción de la mañana: tira reactiva y sedimento urinario y proteinuria. Los estudiantes con TFG < 60 mL/min/1,73m2, proteinuria, hematuria y/o cilindruria fueron reevaluados a los 3 meses para establecer la cronicidad de los hallazgos. RESULTADOS: En la primera visita 27,2% de los estudiantes presentó proteinuria> 150 mg/24 h, 8,6% hematuria y 1,2% cilindruria, aisladas o combinadas, con TFG > 60 mL/min/1,73m2, y 1,2% presentó TFG < 60 mL/min/1,73m2. En la reevaluación a los 3 meses los hallazgos fueron persistentes en 11,2% de los sujetos estudiados. CONCLUSIONES: La proporción hallada de jóvenes aparentemente sanos con función renal disminuida o marcadores de daño renal persistentes en un seguimiento superior a 3 meses aporta evidencia a la dimensión del problema de la enfermedad renal crónica


INTRODUCTION: Early stages of chronic kidney disease (CKD) are asymptomatic and patients may ignore their condition or discover it in a routine medical consultation or because of the consultation about other disease. CKD high global prevalence is accepted. Reliable data is needed to provide evidence and knowledge about the disease in the region. METHODS: Descriptive study. 81 students. Period May 2014 to December 2015. Glomerular Filtration Rate, GFR, was estimated by CKD-EPI and creatinine clearance. Kidney damage was determined in 1st morning urine: test strip and urinary sediment and proteinuria. Students with GFR <60 mL/min/1.73m2, proteinuria, hematuria and / or cylindruria were reassessed at 3 months to establish chronicity. RESULTS: In the first visit 27.2% of the students presented proteinuria >150 mg/24 h; 8.6% hematuria and 1.2% cylindruria, isolated or combined with GFR<60 ml/min/1.73m2 and 1.2% had GFR <60 ml/min/1.73m2. At 3 months reevaluation persistent findings were seen in 11.2% of the subjects studied. CONCLUSIONS: The high proportion of apparently healthy young people with persistent impaired renal function or markers of renal damage in a follow-up greater than 3 months provides an evidence of the magnitude of the CKD problem

ABSTRACT

Objective To investigate the combined detection of serum cystatin C (Cys‐C ) and homocysteine (Hcy) for the diagnosis of early renal damage in diabetic children. Methods Data of 97 cases of diabetic children were collected in our hospital. According to the levels of 24 hUAER ,diabetic children were divided into <30 mg group (n=34) ,30~299 mg group (n=42) ,and ≥300 mg group (n=21). 40 cases of healthy children were selected as control group (NC). Laboratory indexes were compared among different groups. The critical values of Cys‐C and Hcy in early diagnosis of renal damage were calculated by receiver operating curve (ROC). Results The levels of Cys‐C and Hcy in <30 mg group were significantly higher than in NC group [Cys‐C (1.04 ± 0.26 ) vs(0.79 ± 0.21 ) mg/L ,Hcy (13.09 ± 2.15) vs(8.57 ± 1.24)μmol/L ,respectively ,P< 0.05]. When Cys‐C cutoff point took 1.02 mg/L ,the diagnosis sensitivity for diabetic nephropathy diagnosis was 86.09% and the specificity was 83.28% ,the maximum diagnostic index reached 1.6937 ,ROC area under the curve was 0.841.When Hcy threshold took 13.00 μmol/L ,the sensitivity was 83.98% and the specificity was 79.24% ,with the maximum diagnostic index 1.6322 and ROC area 0.795.Cys‐C combined with Hcy had a sensitivity of 92.38% and a specificity of 89.17% ,with the maximum diagnostic index 1.764 and ROC area 0.928. Conclusion Cys‐C combined with Hcy detection for early diagnosis of renal injury in diabetic children has important clinical value.

ABSTRACT

Objective To evaluate the efficacy and safety of different doses of prednisone combined with cyclosporine A(CSA) on the treatment of idiopathic membranous nephropathy (IMN). Methods The data of 64 patients with nephrotic syndrome (NS) diagnosed as IMN by renal biopsy were retrospectively analyzed. Median follow?up time was 10 (7, 19) months. The subjects were divided into 2 groups according to different prednisone dosage. Thirty?two cases were in the low?dose group:prednisone 0.15 mg·kg-1·d-1+CSA, and 32 cases in the moderate?dose group:prednisone 0.4?0.5 mg· kg-1·d-1+CSA. Clinical and laboratory data were collected at baseline, 1, 3, and 6 months after treatment. During follow?up, cumulative recurrence rate and adverse reactions after treatment were recorded. Results Serum albumin (sALB) were significantly increased and 24 h urinary protein (24hUP) significantly decreased after treatment for 1, 3, 6 months compared with baseline data in the two groups. Serum creatine (Scr) increased after treatment with time. The elevation of sALB and the reduction of 24hUP in the moderate?dose group were higher than that of low?dose group at 6 months after treatment (P3 mg·kg-1·d-1 subgroup were 76.5% and 53.3%, respectively (P=0.296); In moderate?dose group:the effective rates of CSA3 mg·kg-1·d-1 subgroup were 89.5%and 84.6%, respectively (P=0.077); there were similar effects in patients treated with different dose CSA in the two groups. About 20.4% of the total patients relapsed when followed up for 18 months (low dose group vs moderate?dose group: 9.5% vs 28.6%, P=0.136), which most occurred after prednisone withdrawal or during the reduction of cyclosporine. Renal function decreased in 57.8% patients (low dose group vs moderate?dose group:50%vs 65.6%), mainly in the elderly (9/11) and the long course of treatment of CSA. There was no significant difference on adverse reactions between the two groups (P>0.05). Renal function in patients with high Scr or high blood trough concentration of cyclosporine was difficult to fully recover. Conclusions Remission rate is lower in low?dose prednisone combined with cyclosporine than the moderate?dose group in the treatment of IMN for 6 months. The recurrence rate of IMN or the incidence of adverse reactions are similar between the two groups. Induction therapy of IMN with cyclosporin<3 mg·kg-1·d-1 is safe and effective. The incidence of renal function reduction in the elderly is high, and the renal function is difficult to restore in patients with Scr exceeding normal upper limits.

ABSTRACT

OBJECTIVE:To explore the effect of different doses of Simvastatin on the related indexes of patients with con-trast-induced nephropathy(CIN). METHODS:168 patients received coronary angiography surgery(CAG)and percutaneous coro-nary stent implantation(PCI)were randomly divided into control group(42 cases),low-dose(42 cases),medium-dose(42 cas-es)and high-dose groups(42 cases),all patients were given Lohexol injection 20 ml. 0.9% Sodium chloride injection was intrave-nously infused at a rate of 2 ml/(kg·h)4 h before radiography until the end,then 0.9% Sodium chloride injection was still intrave-nously infused at a rate of 2 ml/(kg·h)in the end and 48 h after radiography. 48 h before radiography,low-dose group was orally given Simvastatin tablet 20 mg Medium-dose group was orally given Simvastatin tablet 40 mg. high-dose group was orally given Simvastatin tablet 80 mg,once a day. All patients were treated for 4 d. Kidney function indexes(Scr,Ccr,BUN),kidney damage indexes(CysC,NGAL,mAlb),and inflammatory cytokines[(IL)-6,hs-CRP)] before and after radiography,and the incidences of CIN and adverse reactions in all group were observed. RESULTS:After radiography,kidney function indexes,NGAL and mAlb in all group,CysC in control group and low-dose group,CysC after 48 h radiography in medium-dose,high-dose groups were signifi-cantly higher than before,while all the indexes after 24 h radiography in medium-dose,high-dose groups were lower than low-dose group and control group,with statistical significances (P<0.05);after 48 h radiography,medium-dose,high-dose groups were lower than low-dose group,which was lower than control group,with statistical significances(P<0.05). After radiography,the in-flammatory cytokines in all groups were significantly higher than before,while medium-dose,high-dose groups were lower than low-dose group,which was lower than control group,with statistical significances (P<0.05). The incidence of CIN in medi-um-dose,high-dose groups were lower than low-dose group,which was lower than control group,with statistical significances (P<0.05). The incidence of adverse reactions in high-dose group was higher than medium-dose group,followed by low-dose group and control group,with statistical significances (P<0.05). CONCLUSIONS:Both medium-dose and high-dose of Simvas-tatin can effectively reduce the incidence of CIN,improve kidney functions,and reduce kidney damage indexes and inflammatory cytokine levels,while the safety of medium-dose is superior to high-dose.
