It is assumed to have various health benefits. However, the synergistic mixture of the content has not been studied scientifically, hence the need to evaluate its effect on the liver and kidney being part of the body’s metabolic organs. Aim: This study evaluated the synergistic mixture of Cyperus esculentus, Phoenix dactylifera and Cocos nucifera (STCD) aqueous extract in male albino rats. Methods: Acute toxicity LD<sub>50</sub> of STCD was carried out, afterwards, fifteen male albino rats were grouped into three groups with 5 rats in each group;Control, 200 mg/kg, 400 mg/kg STCD. The rats were administered STCD orally 24 hourly, for 21 days, with feed and water ad libitum. At the end of the experiment, blood samples were collected for biochemical analysis of the liver and kidney biomarkers, while the liver and kidney tissues were harvested for histopathological examination using standard laboratory methods. Descriptive statistics were computed and expressed as Mean ± SD. One-way ANOVA and Turkeys test was performed. P value ≤0.05 was considered statistically significant. Results: Acute toxicity LD50 of STCD was observed to be ≥2404.2 mg/kg body weight. An increase in the percentage body weight difference of 8.39% and 2.86% was observed for 200 and 400 mg/kg STCD groups. Also, the liver weight was observed to increase in 400 mg/kg (3.92 ± 1.42) in comparison to the control group (3.48 ± 1.61), a decrease in the kidney weight was observed in all groups administered STCD in comparison to the control group. Administration of STCD at both 200 and 400 mg/kg revealed a decrease in the concentration of the hepatic biomarkers AST, ALT, ALP, TP, Albumin, Total and conjugated bilirubin. The kidney biomarker Urea was observed to decrease in concentration for 200 mg/kg STCD (4.60 ± 1.83) and 400 mg/kg STCD (4.76 ± 0.74) when compared to the control group (6.32 ± 2.74). A decrease in Creatinine was observed in 200 mg/kg (91.80 ± 34.69) and 400 mg/kg (98.60 ± 15.53) in comparison to the control group (117.60 ± 42.88). The histological examination of the liver of rats administered STCD revealed structural normal central vein, hepatocytes and portal tract. The kidney examination revealed normal glomeruli and normal tubule. Conclusion: The findings of this study opine that STCD improved the health of both the liver and kidney as evidenced via the biomarkers and histological examinations of the liver and kidney. This study therefore recommends the intake of STCD at moderate doses for improved liver and kidney function due to its bioactive compounds and nutritional content.展开更多

ESLD was defined as having histological features of cirrhosis and/or radiological evidence of cirrhosis in the context of portal hypertension(ascites,variceal bleeding,thrombocytopenia,or hepatic encephalopathy). A1 ATD was diagnosed using phenotype characterization(MZ or ZZ),liver biopsy detection of PAS-positive diastaseresistant(PAS+) globules,or both. Patients with other causes of liver diseases such as hepatitis C virus(HCV),alcoholic liver disease and non-alcoholic steatohepatitis(NASH) or NASH were also included in the study. HCC was diagnosed by using imaging modalities,biopsy findings,or explanted liver inspection. Follow-up time was defined as the number of years from the diagnosis of cirrhosis to the diagnosis of hepatocellular carcinoma,or from the diagnosis of cirrhosis to the last follow up visit. The rate of HCC was assessed using time-tointerval analysis for interval censored data.RESULTS:This study included 675 patients. 7% of subjects had A1ATD(n = 47). Out of all subjects who did not have A1 ATD,46% had HCV,17% had alcoholic liver disease,19% had NASH and 18% had another primary diagnosis. Of the 47 subjects with A1 ATD,15 had a primary diagnosis of A1ATD(PI*ZZ phenotype and PAS+ globules),8 had a PI*MZ phenotype alone,14 had PAS+ alone,and 10 had both the PI*MZ phenotype and PAS+. Median follow-up time was 3.4(25th,75 th percentiles:1,5.2) years. The overall rate of hepatocellular carcinoma in all subjects was 29%(n = 199). In the A1 ATD group,the incidence rate of HCC was 8.5% compared to 31% in the group of patients with other causes of cirrhosis(P = 0.001). Patients with ESLD due to A1 ATD had the lowest yearly cumulative rate of hepatocellular carcinoma at 0.88% per year compared to 2.7% for those with HCV cirrhosis,1.5% in patients with NASH and 0.9% in alcohol-induced liver disease(P < 0.001).CONCLUSION:Within this group of patients with ESLD,there was no significant association between A1 ATD and increased risk of HCC.展开更多

NAs are considered the most proper approach for HBV infection in patients under renal replacement therapy but their doses should be adjusted according to the patient's creatinine clearance. In addition, physi-cians should be aware of the potential nephrotoxicity. However, patients with chronic hepatitis C and decom-pensated cirrhosis can receive only one therapeutic option before LT, as well as for Hepatitis C virus(HCV) recurrence after LT, which is the combination of sub-cutaneous Peg-IFN and ribavirin. Generally, therapy for HCV after renal transplantation should be avoided. Although the optimal antiviral therapy for HCV infec-tion has not been established, attention has turned to a new, oral direct acting antiviral treatment which marks a promising strategy in prognosis and in amelioration of these diseases.展开更多

文摘BACKGROUND Obesity usually causes diabetes mellitus(DM)and is a serious danger to human health.Type 2 DM(T2DM)mostly occurs along with obesity.Foodborne obesityinduced DM is caused by an excessive long-term diet and surplus energy.Bariatric surgery can improve the symptoms of T2DM in some obese patients.But different types of bariatric surgery may have different effects.AIM To investigate the effect of bariatric surgery on glucose and lipid metabolism and liver and kidney function in rats.METHODS Male Sprague-Dawley rats aged 6-8 wk underwent Roux-en-Y gastric bypass surgery(RYGB),sleeve gastrectomy(SG),or gastric banding(GB).Glucose and insulin tolerance tests,analyses of biochemical parameters,histological examination,western blot,and quantitative real-time polymerase chain reaction were conducted.RESULTS In comparison to the sham operation group,the RYGB,SG,and GB groups had decreased body weight and food intake,reduced glucose intolerance and insulin insensitivity,downregulated biochemical parameters,alleviated morphological changes in the liver and kidneys,and decreased levels of protein kinase Cβ/P66shc.The effect in the RYGB group was better than that in the SG and GB groups.CONCLUSION These results suggest that RYGB,SG and GB may be helpful for the treatment of foodborne obesity-induced DM.
文摘Background: The synergistic mixture of Cyperus esculentus, Phoenix dactylifera and Cocos nucifera (STCD) aqueous extract is a common drink in Port Harcourt, Nigeria. It is assumed to have various health benefits. However, the synergistic mixture of the content has not been studied scientifically, hence the need to evaluate its effect on the liver and kidney being part of the body’s metabolic organs. Aim: This study evaluated the synergistic mixture of Cyperus esculentus, Phoenix dactylifera and Cocos nucifera (STCD) aqueous extract in male albino rats. Methods: Acute toxicity LD<sub>50</sub> of STCD was carried out, afterwards, fifteen male albino rats were grouped into three groups with 5 rats in each group;Control, 200 mg/kg, 400 mg/kg STCD. The rats were administered STCD orally 24 hourly, for 21 days, with feed and water ad libitum. At the end of the experiment, blood samples were collected for biochemical analysis of the liver and kidney biomarkers, while the liver and kidney tissues were harvested for histopathological examination using standard laboratory methods. Descriptive statistics were computed and expressed as Mean ± SD. One-way ANOVA and Turkeys test was performed. P value ≤0.05 was considered statistically significant. Results: Acute toxicity LD50 of STCD was observed to be ≥2404.2 mg/kg body weight. An increase in the percentage body weight difference of 8.39% and 2.86% was observed for 200 and 400 mg/kg STCD groups. Also, the liver weight was observed to increase in 400 mg/kg (3.92 ± 1.42) in comparison to the control group (3.48 ± 1.61), a decrease in the kidney weight was observed in all groups administered STCD in comparison to the control group. Administration of STCD at both 200 and 400 mg/kg revealed a decrease in the concentration of the hepatic biomarkers AST, ALT, ALP, TP, Albumin, Total and conjugated bilirubin. The kidney biomarker Urea was observed to decrease in concentration for 200 mg/kg STCD (4.60 ± 1.83) and 400 mg/kg STCD (4.76 ± 0.74) when compared to the control group (6.32 ± 2.74). A decrease in Creatinine was observed in 200 mg/kg (91.80 ± 34.69) and 400 mg/kg (98.60 ± 15.53) in comparison to the control group (117.60 ± 42.88). The histological examination of the liver of rats administered STCD revealed structural normal central vein, hepatocytes and portal tract. The kidney examination revealed normal glomeruli and normal tubule. Conclusion: The findings of this study opine that STCD improved the health of both the liver and kidney as evidenced via the biomarkers and histological examinations of the liver and kidney. This study therefore recommends the intake of STCD at moderate doses for improved liver and kidney function due to its bioactive compounds and nutritional content.

文摘BACKGROUND Diabetes is known damage the liver and kidney,leading to hepatic dysfunction and kidney failure.Honey is believed to help in lowering the blood glucose levels of diabetic patients and reducing diabetic complications.However,the effect of stingless bee honey(SBH)administration in relieving liver and kidney damage in diabetes has not been well-studied.AIM To investigate the effect of SBH administration on the kidney and liver of streptozotocin-induced(STZ;55 mg/kg)diabetic Sprague Dawley rats.METHODS The rats were grouped as follows(n=6 per group):non-diabetic(ND),untreated diabetic(UNT),metformin-treated(MET),and SBH+metformin-treated(SBME)groups.After successful diabetic induction,ND and UNT rats were given normal saline,whereas the treatment groups received SBH(2.0 g/kg and/or metformin(250 mg/kg)for 12 d.Serum biochemical parameters and histological changes using hematoxylin and eosin(H&E)and periodic acid–Schiff(PAS)staining were evaluated.RESULTS On H&E and PAS staining,the ND group showed normal architecture and cellularity of Bowman’s capsule and tubules,whereas the UNT and MET groups had an increased glomerular cellularity and thickened basement membrane.The SBH-treated group showed a decrease in hydropic changes and mild cellularity of the glomerulus vs the ND group based on H&E staining,but the two were similar on PAS staining.Likewise,the SBME-treated group had an increase in cellularity of the glomerulus on H&E staining,but it was comparable to the SBH and ND groups on PAS staining.UNT diabetic rats had tubular hydropic tubules,which were smaller than other groups.Reduced fatty vacuole formation and dilated blood sinusoids in liver tissue were seen in the SBH group.Conversely,the UNT group had high glucose levels,which subsequently increased MDA levels,ultimately leading to liver damage.SBH treatment reduced this damage,as evidenced by having the lowest fasting glucose,serum alanine transaminase,aspartate transaminase,and alkaline phosphatase levels compared to other groups,although the levels of liver enzymes were not statistically significant.CONCLUSION The cellularity of the Bowman’s capsule,as well as histological alteration of kidney tubules,glomerular membranes,and liver tissues in diabetic rats after oral SBH resembled those of ND rats.Therefore,SBH exhibited a protective hepatorenal effect in a diabetic rat model.
文摘BACKGROUND Primary hyperoxaluria type 1(PH1)is a rare autosomal recessive disease stemming from a deficiency in liver-specific alanine-glyoxylate aminotransferase,resulting in increased endogenous oxalate deposition and end-stage renal disease.Organ transplantation is the only effective treatment.However,its approach and timing remain controversial.CASE SUMMARY We retrospectively analyzed 5 patients diagnosed with PH1 from the Liver Transplant Center of the Beijing Friendship Hospital from March 2017 to December 2020.Our cohort included 4 males and 1 female.The median age at onset was 4.0 years(range:1.0-5.0),age at diagnosis was 12.2 years(range:6.7-23.5),age at liver transplantation(LT)was 12.2 years(range:7.0-25.1),and the follow-up time was 26.3 mo(range:12.8-40.1).All patients had delayed diagnosis,and 3patients had progressed to end-stage renal disease by the time they were diagnosed.Two patients received preemptive LT;their estimated glomerular filtration rate was maintained at>120 mL/min/1.73 m2,indicating a better prognosis.Three patients received sequential liver and kidney transplantation.After transplantation,serum and urinary oxalate decreased,and liver function recovered.At the last follow-up,the estimated glomerular filtration rates of the latter 3 patients were 179,52 and 21 mL/min/1.73 m2.CONCLUSION Different transplantation strategies should be adopted for patients based on their renal function stage.Preemptive-LT offers a good therapeutic approach for PH1.

文摘Gluconeogenesis is an endogenous process of glucose production from noncarbohydrate carbon substrates.Both the liver and kidneys express the key enzymes necessary for endogenous glucose production and its export into circulation.We would be remiss to add that more recently gluconeogenesis has been described in the small intestine,especially under high-protein,lowcarbohydrate diets.The contribution of the liver glucose release,the net glucose flux,towards systemic glucose is already well known.The liver is,in most instances,the primary bulk contributor due to the sheer size of the organ(on average,over 1 kg).The contribution of the kidney(at just over 100 g each)to endogenous glucose production is often under-appreciated,especially on a weight basis.Glucose is released from the liver through the process of glycogenolysis and gluconeogenesis.Renal glucose release is almost exclusively due to gluconeogenesis,which occurs in only a fraction of the cells in that organ(proximal tubule cells).Thus,the efficiency of glucose production from other carbon sources may be superior in the kidney relative to the liver or at least on the level.In both these tissues,gluconeogenesis regulation is under tight hormonal control and depends on the availability of substrates.Liver and renal gluconeogenesis are differentially regulated under various pathological conditions.The impact of one source vs the other changes,based on post-prandial state,acid-base balance,hormonal status,and other less understood factors.Which organ has the oar(is more influential)in driving systemic glucose homeostasis is still inconclusive and likely changes with the daily rhythms of life.We reviewed the literature on the differences in gluconeogenesis regulation between the kidneys and the liver to gain an insight into who drives the systemic glucose levels under various physiological and pathological conditions.
文摘BACKGROUND Non-liquefied multiple liver abscesses(NMLA)can induce sepsis,septic shock,sepsis-associated kidney injury(SA-AKI),and multiple organ failure.The inability to perform ultrasound-guided puncture and drainage to eradicate the primary disease may allow for the persistence of bacterial endotoxins and endogenous cytokines,exacerbating organ damage,and potentially causing immunosuppression and T-cell exhaustion.Therefore,the search for additional effective treatments that complement antibiotic therapy is of great importance.CASE SUMMARY A 45-year-old critically ill female patient presented to our hospital’s intensive care unit with intermittent vomiting,diarrhea,and decreased urine output.The patient exhibited a temperature of 37.8℃.Based on the results of liver ultrasonography,laboratory tests,fever,and oliguria,the patient was diagnosed with NMLA,sepsis,SA-AKI,and immunosuppression.We administered antibiotic therapy,entire care,continuous renal replacement therapy(CRRT)with an M100 hemofilter,and hemoperfusion(HP)with an HA380 hemofilter.The aforementioned treatment resulted in a substantial reduction in disease severity scores and a decrease in the extent of infection and inflammatory factors.In addition,the treatment stimulated the expansion of the cluster of differentiation 8^(+)(CD8^(+))Tcells and led to the complete recovery of renal function.The patient was discharged from the hospital.During the follow-up period of 28 d,she recovered successfully.CONCLUSION Based on the entire therapeutic regimen,the early combination of CRRT and HP therapy may control sepsis caused by NMLA and help control infections,reduce inflammatory responses,and improve CD8^(+)T-cell immune function.

文摘[Objectives]To observe the clinical efficacy of Modified Huan'gan Lipi Decoction combined with acupuncture in the treatment of spleen deficiency and liver hyperactivity type tic disorders(TD).[Methods]Sixty patients with spleen deficiency and liver hyperactivity type TD were randomly divided into a treatment group of 40 cases and a control group of 20 cases.The treatment group received Modified Huan'gan Lipi Decoction combined with acupuncture,and the control group received Haloperidol Tablets.After 4 weeks of treatment,the Yale Global Tic Severity Scale(YGTSS)score,the total score of TCM syndrome and the clinical efficacy were compared between the two groups before and after treatment.[Results]After treatment,the total effective rate of 87.5%in the treatment group was higher than 80.0%in the control group(P>0.05);the total score of YGTSS and the total score of TCM syndromes in the two groups were compared within groups,P﹤0.01;between groups,P﹤0.01.The recurrence rates of the treatment group and the control group were 11.1%and 71.4%,respectively.The difference between the two groups was statistically significant(P﹤0.01).[Conclusions]Modified Huan'gan Lipi Decoction combined with acupuncture in the treatment of spleen deficiency and liver hyperactivity type TD can significantly improve the patient's tic symptoms,and its long-term efficacy is stable.
文摘AIM:To assess and correlate the lipid content of various organs in obese subjects and in persons with a normal body weight.METHODS:Magnetic resonance spectroscopy and a previously validated gradient echo magnetic resonance imaging method with Dixon's two point technique were used in this study to quantify fat in liver,pancreas as well as kidney.RESULTS:In 36 volunteers with body mass index(BMI) ranging from 20.0 to 42.9 kg/m2,the median fat content of liver,pancreas and kidney was 2.3%(interquartile range:0.2%-7.8%),2.7%(1.0%-6.5%) and 0.7%(0.1%-1.4%),respectively.BMI and subcutaneous fat correlated significantly with liver and pancreas fat content.We show for the first time the significant correlation of liver and pancreas fat content in healthy controls(r = 0.43,P < 0.01).These observations are related to body weight as measured by BMI and the amount of subcutaneous fat.Kidney fat content is very low and correlates with none of the other fat depots.CONCLUSION:Renal lipid accumulation,unlike the coupled accumulations of fat in liver and pancreas,is not observed in obese subjects.Unlike suggestions made in previous studies,renal lipid accumulation appears not to be involved in the pathogenesis of renal disease in humans.
文摘AIM:To evaluate the association between alpha-1 antitrypsin deficiency(A1ATD) and hepatocellular carcinoma(HCC) in patients with end-stage liver disease(ESLD).METHODS:Patients with cirrhosis and ESLD referred to the Cleveland Clinic Foundation for liver transplantation between 2003 and 2014 were included in the study(N = 675). ESLD was defined as having histological features of cirrhosis and/or radiological evidence of cirrhosis in the context of portal hypertension(ascites,variceal bleeding,thrombocytopenia,or hepatic encephalopathy). A1 ATD was diagnosed using phenotype characterization(MZ or ZZ),liver biopsy detection of PAS-positive diastaseresistant(PAS+) globules,or both. Patients with other causes of liver diseases such as hepatitis C virus(HCV),alcoholic liver disease and non-alcoholic steatohepatitis(NASH) or NASH were also included in the study. HCC was diagnosed by using imaging modalities,biopsy findings,or explanted liver inspection. Follow-up time was defined as the number of years from the diagnosis of cirrhosis to the diagnosis of hepatocellular carcinoma,or from the diagnosis of cirrhosis to the last follow up visit. The rate of HCC was assessed using time-tointerval analysis for interval censored data.RESULTS:This study included 675 patients. 7% of subjects had A1ATD(n = 47). Out of all subjects who did not have A1 ATD,46% had HCV,17% had alcoholic liver disease,19% had NASH and 18% had another primary diagnosis. Of the 47 subjects with A1 ATD,15 had a primary diagnosis of A1ATD(PI*ZZ phenotype and PAS+ globules),8 had a PI*MZ phenotype alone,14 had PAS+ alone,and 10 had both the PI*MZ phenotype and PAS+. Median follow-up time was 3.4(25th,75 th percentiles:1,5.2) years. The overall rate of hepatocellular carcinoma in all subjects was 29%(n = 199). In the A1 ATD group,the incidence rate of HCC was 8.5% compared to 31% in the group of patients with other causes of cirrhosis(P = 0.001). Patients with ESLD due to A1 ATD had the lowest yearly cumulative rate of hepatocellular carcinoma at 0.88% per year compared to 2.7% for those with HCV cirrhosis,1.5% in patients with NASH and 0.9% in alcohol-induced liver disease(P < 0.001).CONCLUSION:Within this group of patients with ESLD,there was no significant association between A1 ATD and increased risk of HCC.
文摘New nucleos(t)ide analogues(NAs) with high genetic barrier to hepatitis B virus(HBV) resistance(such as entecavir, tenofovir) have improved the prognosis of patients with HBV decompensated cirrhosis and have prevented HBV recurrence after liver transplantation(LT). NAs are considered the most proper approach for HBV infection in patients under renal replacement therapy but their doses should be adjusted according to the patient's creatinine clearance. In addition, physi-cians should be aware of the potential nephrotoxicity. However, patients with chronic hepatitis C and decom-pensated cirrhosis can receive only one therapeutic option before LT, as well as for Hepatitis C virus(HCV) recurrence after LT, which is the combination of sub-cutaneous Peg-IFN and ribavirin. Generally, therapy for HCV after renal transplantation should be avoided. Although the optimal antiviral therapy for HCV infec-tion has not been established, attention has turned to a new, oral direct acting antiviral treatment which marks a promising strategy in prognosis and in amelioration of these diseases.

文摘BACKGROUND Acute kidney injury(AKI)after liver transplantation(LT)is a frequent and multifactorial event related to increased morbidity and mortality.Risk factors for AKI after LT still need to be clarified.AIM To identify the predictors of acute kidney injury after liver transplantation.METHODS The frequency and pre-and intraoperative predictors of AKI within the first 7 d after LT were evaluated in adult liver transplant candidates in a single LT center in Croatia.AKI was defined according to the Kidney Disease:Improving Global Outcomes criteria.RESULTS Out of 205 patients(mean age 57±10 years;73.7%males,52.7%with alcoholrelated liver disease)93(45.36%)developed AKI,and the majority of them(58.06%)had stage 1.Only 5.38%of patients required renal replacement therapy after LT.The majority of patients(82.8%)developed AKI within the first two days after the procedure.Multivariate logistic regression identified pre-LT body mass index(OR=1.1,95%CI:1.05-1.24)and red blood cell transfusion(OR=1.66,95%CI:1.09-2.53)as independent predictors of early post-LT AKI occurrence.30-d survival after LT was significantly better for patients without AKI(P=0.01).CONCLUSION Early AKI after LT is a frequent event that negatively impacts short-term survival.The pathogenesis of AKI is multifactorial,but pre-LT BMI and intraoperative volume shifts are major contributors.
文摘BACKGROUND Acute kidney injury(AKI)has serious consequences on the prognosis of patients undergoing liver transplantation.Recently,artificial neural network(ANN)was reported to have better predictive ability than the classical logistic regression(LR)for this postoperative outcome.AIM To identify the risk factors of AKI after deceased-donor liver transplantation(DDLT)and compare the prediction performance of ANN with that of LR for this complication.METHODS Adult patients with no evidence of end-stage kidney dysfunction(KD)who underwent the first DDLT according to model for end-stage liver disease(MELD)score allocation system was evaluated.AKI was defined according to the International Club of Ascites criteria,and potential predictors of postoperative AKI were identified by LR.The prediction performance of both ANN and LR was tested.RESULTS The incidence of AKI was 60.6%(n=88/145)and the following predictors were identified by LR:MELD score>25(odds ratio[OR]=1.999),preoperative kidney dysfunction(OR=1.279),extended criteria donors(OR=1.191),intraoperative arterial hypotension(OR=1.935),intraoperative massive blood transfusion(MBT)(OR=1.830),and postoperative serum lactate(SL)(OR=2.001).The area under the receiver-operating characteristic curve was best for ANN(0.81,95%confidence interval[CI]:0.75-0.83)than for LR(0.71,95%CI:0.67-0.76).The root-mean-square error and mean absolute error in the ANN model were 0.47 and 0.38,respectively.CONCLUSION The severity of liver disease,pre-existing kidney dysfunction,marginal grafts,hemodynamic instability,MBT,and SL are predictors of postoperative AKI,and ANN has better prediction performance than LR in this scenario.
