Significant Differences In Urea Research Articles

Biochemical changes associated with H. pylori infection in humans

Since its first isolation, H. pylori, a Gram-negative flagellated bacterium, has been the subject of intensive research because of its widespread dissemination and associations with several disorders. The bacterium is proven to be a causative factor for a number of gastric diseases, such as gastritis, gastric adenocarcinoma, and MALT-lymphoma. While H. pylori infection has been reported to be linked to several extra-gastric diseases, this study investigated extra-gastric manifestation of H. pylori using specific biomarkers in humans. The GERDs questionnaire was used to randomly chose 150 (one hundred and fifty) participants, of which 75 (seventy five) were found to be H. pylori positive and another 75 (seventy five) were chosen as negative controls. Samples were gathered, and biochemical characteristics were examined. The study revealed a significant (p<0.05) reduction in the levels of oxidative stress markers, glutathione peroxidase (GPX), vitamin C (vit C) and no significant difference was observed in malondialdehyde (MDA) and Total iron concentrations, although with a mean increase and reduction respectively. For the lipid profile biomarker results were statistically (p<0.05) significant for triglyceride (TG) and low density lipoprotein(LDLc) while no significant difference was observed in total cholesterol (TC) and high density lipoprotein (HDLc). Kidney function assessment revealed a statistical (p > 0.05) no significant different with sodium (Na+), potassium (K+), chloride (Cl-) and bicarbonate (HCO2-) concentrations while there was a significant difference in urea and creatinine concentrations when compared with the control subjects. In the liver function parameters, a statistical (p<0.05) significant difference was observed with the aminotransferases (ALT, AST, ALP) and conjugated bilirubin while total bilirubin had a no significant difference when compared with the control subjects. A correlation coefficient analysis of parameter in H. pylori positive subjects were significantly adjusted (p<0.05) for TG, total cholesterol, aminotransferases and bilirubin. The aim of the study was to investigate the biochemical changes of H. pylori infection in humans using specific biomarkers.

Plasma urea:creatinine ratio as a biomarker of gastrointestinal bleeding in dogs with anaemia.

Gastrointestinal bleeding is a cause of anaemia in dogs. A reliable, non-invasive biomarker to differentiate gastrointestinal bleeding from other causes of anaemia would be advantageous to direct clinical decisions in anaemic patients. Plasma urea:creatinine ratio is an accepted biomarker of upper gastrointestinal bleeding in human medicine. The objective of this study was to evaluate plasma urea:creatinine ratio as a biomarker of gastrointestinal bleeding in a population of dogs with anaemia. This was a prospective cross-sectional study of dogs with anaemia presenting to referral centres for the investigation of anaemia. Cases were categorised as having overt gastrointestinal bleeding (melena on presentation), occult gastrointestinal bleeding (historical and diagnostic findings consistent with gastrointestinal bleeding without melena at presentation) or anaemia of other cause (confident diagnosis other than gastrointestinal bleeding reached, normal diagnostic imaging of gastrointestinal tract). Urea:creatinine ratio at presentation was calculated by dividing urea (mg/dL) by creatinine (mg/dL). Ninety-five dogs were included. Plasma urea:creatinine ratio was not significantly different between dogs with overt or occult gastrointestinal bleeding or those with anaemia of other cause (median urea:creatinine ratio 25.8, 20.7 and 22.5, respectively). No significant difference in urea:creatinine ratio was found between dogs with upper and lower gastrointestinal bleeding (median urea:creatinine ratio 19.4 and 24.6, respectively). Plasma urea:creatinine ratio was not helpful in differentiating between dogs with anaemia resulting from gastrointestinal bleeding (overt or occult) and those with other causes of anaemia.

Decoding renal impact: An in-depth study on kidney function in COVID-19 patients at a tertiary care facility

ABSTRACT Background: The emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has marked a pivotal epoch in infectious diseases, surpassing its predecessors in global impact. This study investigates the intricate dynamics of SARS-CoV-2’s impact on renal function, recognizing kidneys as a significant focal point beyond its pulmonary implications. Aims and Objectives: The primary aim is to comprehensively assess the renal implications of COVID-19, considering biochemical profiles and complications, particularly in chronic dialysis and kidney transplant recipients. This study aims to delineate the stages of severe COVID-19, emphasizing acute kidney injury (AKI), and explore distinctive clinical considerations surrounding COVID-19’s impact on renal health. Materials and Methods: A total of 486 adult patients hospitalized for COVID-19 at Santosh Hospital, Ghaziabad, between May 2020 and June 2021, were enrolled. Stratified into Mild, Moderate, and Severe categories, clinical presentations were analyzed using the One-way Analysis of Variance (ANOVA) test for robust comparisons. Statistical significance, guided by a p-value <0.05, ensured meticulous data interpretation. Results: The age distribution revealed varying patterns across severity groups, with notable differences in biochemical parameters. There was a statistically significant difference in urea, creatinine, uric acid, and potassium levels between mild, moderate, and severe cases. Severe patients exhibited higher levels, particularly in urea and creatinine. Gender-wise, males dominated severe cases, underscoring potential risk factors. Conclusion: This study unravels the multifaceted impact of COVID-19 on renal function, emphasizing acute kidney injury in severe cases. The elevated risk observed in chronic dialysis patients and kidney transplant recipients highlights the need for vigilant monitoring. Despite unexpected normative electrolyte findings, the study underscores the dynamic and systemic nature of the disease beyond respiratory implications. These insights contribute to a nuanced understanding of COVID-19, urging comprehensive patient assessments and targeted interventions, especially for those with pre-existing kidney conditions. As the world grapples with ongoing waves and emerging variants, continual research into the complexities of COVID-19 remains paramount for clinicians and researchers alike.

Evaluating several clinical and subclinical characteristics of patients pre- and post-kidney transplant at 103 Military Hospital

Objective: To describe several clinical and subclinical characteristics of patients before and after 6 months of kidney transplant at 103 Military Hospital. Subject and method: From March 2018 to April 2020, a prospective, descriptive study enrolled 75 recipients with 6 months after renal transplant at 103 Military Hospital. Result: Prior to transplantation, 80.3% of patients received dialysis with an artificial kidney, while 9.8% received medical treatment; more than 90% of patients had hypertension, anemia, and dyslipidemia, with 43.8% having residual urine loss. The prevalence of HBV and HCV infection were 24.1%, and 95.5% of patients having HLA compatibility from 1-6/6 AG. There was a significant difference in urea, creatinine, uric acid, cholesterol, triglycerides, LDL-C, HDL-C, and hemoglobin before and after transplantation. However, after transplantation, 17.3% and 41.3% of patients had increased urea and creatinine, respectively. There were a 9.3% decrease in glomerular filtration rate and a 5.3% increase in proteinuria. After 6 months of kidney transplantation, indicators such as hypertension, increased CRP, anemia, and left ventricular hypertrophy significantly improved. Conclusion: Six months after transplantation, patients with end-stage renal disease improved in several clinical and subclinical indicators. Patients may still experience several metabolic disorders after transplantation, such as diabetes, decreased glomerular filtration rate, and increased proteinuria.

Association of mean platelet volume/lymphocyte ratio with inflammation in non-dialysis patients with chronic kidney disease stages 1-4: A retrospective study.

The mean platelet volume/ratio (MPVLR) is recognized as a novel marker of inflammation. We evaluated whether the MPVLR is associated with inflammation in non-dialysis patients with chronic kidney disease (CKD) stages 1-4. A total of 402 non-dialysis patients with CKD stages 1-4 were included. The indicators of hematological, renal function (urea, serum creatinine [Scr], estimated glomerular filtration rate [eGFR], and urine albumin to creatinine ratio [ACR]) and the markers of inflammation (high-sensitivity C-reactive protein [hsCRP] and fibrinogen [FIB]) were recorded. The MPVLR values at different CKD stages were analyzed. Next, based on the absence (hsCRP level < 5 mg/L) and presence (hsCRP level > 5 mg/L) of inflammation, the patients were categorized, and the differences in indices between the two groups were observed. The patients were divided into two groups based on the median MPVLR value (6.39) at admission. The laboratory indices of patients with CKD were compared. Simultaneously, a correlation analysis was performed to identify the association between the MPVLR and each parameter. A binary logistic regression analysis was performed to test whether the MPVLR was associated independently with the presence of inflammation in non-dialysis patients with CKD. The receiver operating characteristic (ROC) curve was used to analyzed diagnostic performance of the MPVLR in evaluating the inflammation of non-dialysis patients with CKD stages 1-4. The MPVLR was higher in patients with CKD stages 3-4 than in those with CKD stages 1 and 2. Significant differences in urea, Scr, eGFR, ACR, lymphocyte (LYM), red blood cell (RBC), hemoglobin (HGB), RBC distribution width (RDW-CV), MPVLR, and FIB values were observed between the groups with and without inflammation. The patients with a higher MPVLR had higher urea, Scr, ACR, WBC, neutrophils (NEU), RDW-CV, platelet distribution width (PDW), mean platelet volume (MPV), and hsCRP values and lower eGFR, LYM, RBC, HGB, and platelet (PLT) values. The MPVLR showed a positive correlation with age, urea, Scr, WBC, NEU, RDW-CV, PDW, MPV, and hsCRP values and a negative correlation with the eGFR, LYM, RBC, HGB, and PLT values. A logistic analysis revealed that the MPVLR was associated independently with the presence of inflammation in non-dialysis patients with CKD, after adjustment for the confounding factors (odds ratio = 1.020; P = 0.024). Furthermore, MPVLR exhibited a modest diagnostic performance for the assessment of inflammation in non-dialysis patients with CKD stages 1-4, with an area under the curve (AUC) of 0.706, and the sensitivity, specificity being 46.2% and 83.2%, respectively. The MPVLR was associated independently with the presence of inflammation in non-dialysis patients with CKD and may be useful for monitoring inflammation.

A Prospective Study Evaluating Cumulative Incidence and a Specific Prediction Rule in Pulmonary Embolism in COVID-19.

RationaleAbnormal values of hypercoagulability biomarkers, such as D-dimer, have been described in Coronavirus Disease 2019 (COVID-19), which has also been associated with disease severity and in-hospital mortality. COVID-19 patients with pneumonia are at greater risk of pulmonary embolism (PE). However, the real incidence of PE is not yet clear, since studies have been limited in size, mostly retrospective, and PE diagnostic procedures were only performed when PE was clinically suspected.Objectives(1) To determine the incidence, clinical, radiological, and biological characteristics, and clinical outcomes of PE among patients hospitalized for COVID-19 pneumonia with D-dimer > 1,000 ng/mL. (2) To develop a prognostic model to predict PE in these patients.MethodsSingle-center prospective cohort study. Consecutive confirmed cases of COVID-19 pneumonia with D-dimer > 1,000 ng/mL underwent computed tomography pulmonary angiography (CTPA). Demographic and laboratory data, comorbidities, CTPA scores, treatments administered, and clinical outcomes were analyzed and compared between patients with and without PE. A risk score was constructed from all these variables.ResultsBetween 6 April 2020 and 2 February 2021, 179 consecutive patients were included. The overall incidence of PE was 39.7% (71 patients) (CI 95%, 32–47%). In patients with PE, emboli were located mainly in segmental/subsegmental arteries (67%). Patients with PE did not differ from the non-PE group in sex, age, or risk factors for thromboembolic disease. Higher urea, D-Dimer, D-dimer-to-ferritin and D-dimer-to-lactate dehydrogenase (LDH) ratios, platelet distribution width (PDW), and neutrophil-to-lymphocyte ratio (NLR) values were found in patients with PE when compared to patients with non-PE. Besides, lymphocyte counts turned out to be lower in patients with PE. A score for PE prediction was constructed with excellent overall performance [area under the ROC curve-receiver operating characteristic (AUC-ROC) 0.81 (95% CI: 0.73–0.89)]. The PATCOM score stands for Pulmonary Artery Thrombosis in COVID-19 Mallorca and includes platelet count, PDW, urea concentration, and D-dimer-to-ferritin ratio.ConclusionCOVID-19 patients with pneumonia and D-dimer values > 1,000 ng/mL were presented with a very high incidence of PE, regardless of clinical suspicion. Significant differences in urea, D-dimer, PDW, NLR, and lymphocyte count were found between patients with PE and non-PE. The PATCOM score is presented in this study as a promising PE prediction rule, although validation in further studies is required.

Effects of Different Anesthetics on Perioperative Organ Protection and Postoperative Cognitive Function in Patients Undergoing Cardiac Valve Replacement with Cardiopulmonary Bypass.

In this paper, we have carried out an experimental study to investigate the effects of different anesthetics on perioperative organ protection and postoperative cognitive function in patients undergoing cardiac valve replacement with cardiopulmonary bypass. To realize this idea, a total of 90 patients with single valve replacement under general anesthesia and hypothermic cardiopulmonary bypass from January 2020 to October 2021 were enrolled. These patients were assigned into three groups, with 30 cases in each group by the digital table method. Group A was anesthetized with sufentanil combined with dexmedetomidine. Group B was anesthetized with sufentanil combined with etomidate. Group C was anesthetized with sufentanil combined with propofol. Perioperative organ protection and postoperative cognitive function of the three groups were compared. At T0 time point, there was no significant difference in blood WBC, blood N, and CRP among groups A, B, and C (P > 0.05); At T4 and T5 time points, the indexes of blood WBC, blood N, and CRP in groups A, B, and C were higher compared to the T0 time point. At T4 and T5 time points, the indexes of blood WBC, blood N, and CRP in group A were significantly lower compared to group B and group C. Before treatment, there was no significant difference in ALT and AST among groups A, B, and C (P > 0.05). After treatment, the indexes of ALT and AST in group A were significantly lower compared to group B and group C at T4 and T5 time points (P < 0.05). Before treatment, there was no significant difference in urea and creatinine among groups A, B, and C (P > 0.05). After treatment, the urea and creatinine indexes of group A were significantly lower compared to group B and group C at T4 and T5 time points (P < 0.05). Before treatment, there was no significant difference in CK-MB and CTnl among groups A, B, and C (P > 0.05); After treatment, the indexes of CK-MB and CTnl in group A were significantly lower compared to group B and group C at T4 and T5 time points (P < 0.05). Before treatment, there was no significant difference in MOCA scores among groups A, B, and C (P > 0.05). After treatment, the MOCA scores of group A were significantly higher compared to group B and group C at T5 and T6 time points (P < 0.05). Sufentanil combined with dexmedetomidine for heart valve replacement under cardiopulmonary bypass can reduce the dosage of anesthetics during the operation and have a certain perioperative protective effect on important organs such as the heart, lung, liver, and kidney, which may be related to reducing intraoperative hemodynamic fluctuations and inhibiting inflammatory stress response.

Acute renal failure in scrub typhus patients

Scrub typhus, a bacterial infection caused by Orientia Tsutsugamushi (formally Rickettsia) due to bite of the mite, and is increasing every year, and becomes a important cause of acute febrile illnesses. Due to lack of specific diagnostic facilities in most rural setups and non-specific clinical presentations, it becomes a challenge for clinician to correctly diagnose it on clinical examination. Clinically it presents with non-specific febrile illnesses with constitutional symptoms such as fever, rash, myalgia and headache or with organ dysfunction involving kidneys, lungs, liver, central nervous system or with circulatory collapse with hemorrhagic features. Eschar is the characteristic lesion which is present at the bite site of mite. Later an ulcer with black necrotic centre and regional lymphadenopathy occurs. Renal involvement in the form of Acute Renal Failure is seen very occasionally in these patients. So this Case-control study is designed for a period of six months which are october-2018 to march-2019, comparing 80 ELISA(Enzyme Linked Immune Sorbent Assay) confirmed cases of scrub typhus and 50 healthy controls. Statistically significant difference in Urea, Creatinine and Uric acid levels were found between two groups, using 't'-test with the significance value of P&amp;#60;0.0001.

The Effect of Two Acute Bouts of Exercise on Oxidative Stress, Hematological, and Biochemical Parameters, and Rectal Temperature in Trained Canicross Dogs.

Canicross is a sport discipline that connects human and canine athletes in running. Changes in physiological, hematological, and biochemical parameters, and exercise-induced oxidative stress have not been thoroughly characterized in canicross dogs. The aim of our study was the assessment of the health status of trained canicross dogs that were subjected to two acute bouts of exercise with their owners during the training season. Health status was assessed by measuring the rectal temperature, hematological and biochemical parameters, as well as blood oxidative stress parameters (plasma malondialdehyde, lipid peroxidation marker; whole blood glutathione peroxidase and erythrocyte superoxide dismutase1, antioxidant enzymes) before and during a two-day canicross training session and after a 24-h rest period. Seven trained canicross dogs (three females/four males) aged 12–120 months were included in the study. Blood samples were collected before and immediately after the first acute bout of exercise (day 1), after the second acute bout of exercise (day 2), and after 24 h of rest (day 3). Rectal temperature was measured at the same time as blood sample collection. The majority of hematological and biochemical parameters remained within reference ranges at all sampling times. Rectal temperature was significantly higher after training on days 1 and 2 compared to resting temperature on day 3. Hematological parameters did not change significantly; however, there were significant differences in urea, creatinine, creatine kinase, and triglycerides between specific sampling times. Despite significant changes, these biochemical parameters remained within reference ranges. Significant changes in biochemical parameters seem to reflect the dogs' physiological response to each acute bout of exercise, considering all biochemical parameters and rectal temperature returned to pre-exercise values after a 24-h rest period (day 3). No significant differences in oxidative stress parameters were found between any sampling times. Relatively high erythrocyte superoxide dismutase1 activity at all sampling times may indicate that the canicross dogs are adapted to training by an increased expression of antioxidant enzymes. Based on our results, we can conclude that the trained canicross dogs included in our study were healthy, in good physical condition, and fit for the two acute bouts of field exercise.

Antioxidant effect of Arrabideae chica (crajiru) extract on oxidative stress in diabetic rats

Objective: This study aimed to investigate the effects of the antioxidant potential of Arrabideae chica (crajiru) extract on oxidative stress in diabetic rats. Methods: Adult Wistar rats (Rattus norvegicus), weighing 238±12g were divided into three groups of six rats each: CN normal untreated control; DIAB+NS diabetic rats treated with normal saline; and diabetic rats treated with crajiru extract, DIAB+CR. The CN and DIAB+NS groups (control groups) received normal saline solution (NS) orally (gavage); rats in the DIAB+CR group received crajiru extract (300 mg/kg) once a day by gavage for 6 weeks. Measurements of urea and creatinine in serum, and kidney tissue catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) were performed. The variables were assessed using the Tukey test, significance p&lt;0.05. Results: All animals survived the experiments. In the CN group, compared with the DIAB+NS group, there was significant difference between the levels of glycemia on the second day of dosing and on the 10th day (p&lt;0.05). No difference was observed on glycemia comparing the 2th and 10th day on the rats of group C+NS (p&gt;0.05). Diabetic animals from DIAB+CR group had a significant reduction in glycemia on 10th day of treatment, comparing the 2nd day (p&lt;0.05). There was a significant reduction in glycemia in the DIAB+CR group, comparing with the DIAB+NS group (p&lt;0.05). There was an increase in urea and creatinine levels in rats DIAB+SN when compared to controls, C+SN (p&lt;0.001). Rats from the DIAB+CR group had a significant reduction in urea and creatinine, compared to the DIAB+NS group (p&lt;0.001). There were no significant differences in urea and creatinine comparing the C+NS and DIAB+CR groups. The rats from the DIAB+NS group had significantly lower levels of CAT, GSH-px and SOD when compared to the normal control rats (p&lt;0.001). In animals from the DIAB+SN group, the levels of these antioxidant enzymes were significantly reduced (p&lt;0.001). The treatment of diabetics with crajiru extract caused a significant increase (p&lt;0.001) in the levels of CAT, GSH-px and SOD, when compared to rats in the BIAB+SN group. Conclusion: The data of the present study confirms that the crajiru extract positively influenced the control of hyperglycemia in diabetic rats. More research is needed to provide a better understanding of the mechanisms of diabetes treatment using crajiru extract and its flavonoids.

Safety Assessment of a New Strain of Lactobacillus pentosus (IBRC=11143) As a Candidate Probiotic

Background: It is believed that the consumption of an adequate amount of live lactic acid bacteria (as probiotic) may improve the health of the host. Many strains of lactic acid bacteria are generally considered to be safe. However, some strains have shown some adverse effects.&#x0D; Objectives: This study aimed to investigate the safety of a new strain of Lactobacillus pentosus (IBRC=11143) in Wistar rats&#x0D; Methods:In this experimental study, male and female Wistar rats (n=6) were used. A subacute toxicity study (for 28 days) was conducted by oral administration of Lactobacillus pentosus to the animals. In each sex, one group received saline, and the other two groups received the bacteria at doses of 1×108 and 1×109 Colony-Forming Units (CFU)/rat.&#x0D; Results: No significant alteration in the liver and kidney tissues was seen. However, in both sexes, there were significant differences in urea and creatinine levels between the control and the experimental groups. Some blood parameters (Lymphocyte, red blood cell, hematocrit, and hemoglobin) also showed significant changes in the groups that received the bacteria. Moreover, a significant increase in alkaline phosphatase level was observed in male rats.&#x0D; Conclusion: The results indicate that Lactobacillus pentosus (11143) is not entirely safe like other Lactobacillus strains. Therefore, the Lactobacillus pentosus (11143) strain may not be the right choice as a probiotic for human consumption.

Hematological and serum biochemistry parameters as a prognostic indicator of severally ill versus mild Covid-19 patients: A study from tertiary hospital in North India

Background/objectivesIn, India coronavirus disease (COVID-19) cases are on the rise in terms of the total number of cases. Findings on clinical and hematological parameters alone carry no significance apart from telling patients present status and hence are diminutive. This study aims to assess the hematological and serum biochemistry parameters and correlate them with the presenting symptoms and severity of disease which can help predict the need for intensive care unit (ICU) care, help in triage, assess the severity of the disease which will help clinicians decide their future course of action and further improve patients clinical outcome. MethodsA total of 200 COVID-19 positive patients were included. Hematological and serum biochemistry parameters were recorded for the patients at the time of admission and categorized as mild, moderate, and severely ill based on clinical status and then admitted into various wards. ResultsTotal leucocyte count (TLC) was significantly different and higher in severely ill patients (13,200 ± 6,999.2) compared to cases presented with mild and moderate symptoms (12,100 ± 6,488.41& 8,788.20 ± 4,954.32, p = 0.001). The mean difference of TLC, Neutrophil% (N%), Lymphocyte% (L%) and Monocyte (M%) was significantly different between mild and moderate symptoms cases (p = 0.030, p = 0.002, p = 0.004 & p = 0.003). Between groups comparison of moderate vs. severely ill cases showed a significant difference in TLC (p = 0.000), N% (p = 0.000), L% (0.000), and L/N ratio (p = 0.002). The serum ionic calcium (Ca), random blood sugar (RBS), C-reactive protein (CRP), fibrinogen, prothrombin (PT), International Normalized Ratio (INR), ferritin, and Lactate Dehydrogenase (LDH) level also differed significantly between mild, moderate and severely ill cases (p = 0.001, p=<0.001, p = 0.002, p=<00.1, p = 0006, p = 0.005, p=<0.001 and p=<0.001) respectively. Comparison of the mild vs. severely ill cases showed a significant difference in urea, fibrinogen, and procalcitonin (PCT) level (p = 0.005, p = 0.000 & p = 0.048) respectively. ConclusionThe preliminary findings of this study suggest hematological and serum biochemistry parameters could be used as a screening tool to identify patients requiring intensive care and thus allowing clinical stratification and triage at the time of presentation.

MO666INVESTIGATIONS INTO DIFFERENCES AND SIMILARITIES BETWEEN SHORT DAILY HIGH-FLUX HEMODIALYSIS AND SHORT DAILY ON-LINE HEMODIAFILTRATION

Abstract Background and Aims Short daily hemodialysis (SDHD) has improved outcomes observed in conventional thrice-weekly hemodialysis (CHD). Analogously, short daily hemodiafiltration (SDHDF) has also improved outcomes observed in conventional thrice-weekly hemodiafiltration (CHDF). Furthermore, while high-volume CHDF has been proclaimed to be superior to CHD, there have been no studies comparing SDHDF to SDHD. We performed a comparison of clinical, laboratory, echocardiographic and quality of life features in dialysis patients treated by SDHD or SDHDF. Method Twelve patients (mean age 60.8±15.4 years; 7 males; AVF 7, AVG 1, Catheter 4) on regular in-center SDHD program were studied in a longitudinal, prospective, non-randomized, single-subject A-B-A design comparing high-flux SDHD to post-dilution on-line SDHDF. Patients had been for at least 6 months on SDHD (105-150min, 6x/week; SDHD1) and were clinically stable before conversion to SDHDF (105-150min, 6x/week, mean total convective volume of 63.57±5.44 L per week) for 6 months. Following that, all patients were switched back to SDHD for another 6 months (SDHD2). Data were collected at the end of each period. Dialysis parameters throughout the study were matched and set as follows: high-flux polysulfone dialyzers (BBraun Xevonta Hi 23®), blood flow 300–350 mL/min, dialysate flow 500 mL/min and ultra-purified water (Aquaboss heat disinfection osmosis). The results were expressed as mean ± standard deviation. Each patient served as his/her own control. Repeated measures analysis of variance (ANOVA) were used. Results Slightly higher predialysis mean arterial pressure (MAP) levels were observed during SDHDF (102.51±11.28 mmHg) compared to SDHD1 (MAP 95.5±9.82 mmHg, p&amp;lt;0.01) or to SDHD2 (97.61±11.19 mmHg, p=0.03), without significant differences in intradialytic blood pressure variability. Similarly, there was an increase in predialysis hemoglobin levels (Hb) during SDHDF (Hb 12.39±1.2 g/dL), compared to SDHD1 (Hb 11.30±1.09 g/dL, p=0.02) or to SDHD2 (Hb 11.23±1.84 g/dL, p&amp;lt;0.01), although there were no significant differences in erythropoietin-stimulating agent or iron supplementation weekly doses, transferrin saturation rates or ferritin levels. Solute kinetics measurements showed higher myoglobin clearance during SDHDF (45.95±11.0 mL/min) compared to SDHD1 (20.11±5.2 mL/min, p&amp;lt;0.01) or to SDHD2 (21.39±3.55 mL/min, p&amp;lt;0.01). Likewise, there was a slight increase in β2-microglobulin removal in SDHDF (64.92±10.4 mL/min) compared to SDHD1 (59.78±17.0 mL/min, p&amp;lt;0.01) or to SDHD1 (53.01±7.71 mL/min, p&amp;lt;0.01), whereas there were no significant differences in urea and creatinine clearances. On the other hand, predialysis osteometabolic (serum PTH, calcium, phosphate, alkaline phosphatase, sodium, potassium, glucose and glycated hemoglobin), inflammatory (serum c-reactive protein and interleukin-6) or nutritional (serum albumin, total protein and lipid profile) parameters did not change significantly during the study. Left ventricular mass index, left atrial volume index and global longitudinal strain, assessed by echocardiography at the end of all 3 periods, were similar, as well as brain natriuretic peptide and homocysteine serum levels. Additionally, there were no significant changes in any quality of life features evaluated by Kidney Disease Quality of Life-Short Form, or symptoms assessed by Edmonton Symptom Assessment System Revised Renal, throughout the full course of the study. Conclusion In spite of mild increase of predialysis mean arterial pressure and hemoglobin levels along with greater removal of middle molecular weight solutes, no others clinical, laboratory, echocardiographic or quality of life findings differed significantly during the three periods. Together, these data do not provide evidence of clinically meaningful benefit from on-line hemodiafiltration over high-flux hemodialysis, both performed six times a week.

Evaluation Of Histological Changes In Kidney Of Male Albino Rats Treated With Silver Nanoparticles

The wide uses of silver nanoparticles in the industrial, medical and cosmetic fields with it ease of entry into human body and absorption by gastrointestinal tract there for designed this study to find out the effect of silver nanoparticles on the tissue structure and functional performance of the kidney, because the process of filtering blood takes place widely in the kidney. 24 male albino rats were used for the experimental study, the rats were divided into three groups, first groups(control) dosage with normal saline solution (Injected intraperitoneal), second group (treatment) dosage with AgNPs0.75mg/kg of body weight and third group (treatment) dosage with AgNPs 1.5mg/kg of body weight. Each concentration of AgNP was dissolved in1ml of normal saline and all experimental male rats were injected via intraperitoneal with single dose /day for30 days. The resultsin this study showed tissue damage in the kidney such as vacuolar and fatty degeneration in renal tubules with pyknic nucleus in glomerulus also appear massive aggregation of mononuclear cells around blood vessels with hemorrhage and hemosiderin in renal tubules with occurrence the amyloid inside the blood vessels with necrosis in different cells associated with malfunction of kidney Shown in significant difference in urea, uric acid and creatinine when compare with control group. Histopathological changes associated with the dysfunction of the kidneys due to the effect of nanoparticles directly on the cells such as the occurrence of the reactive oxygen species (ROS) generation has key role in the events of structural and functional disorders in the kidney of male albino rats.

Performance and blood parameters of Holstein/Zebu crossbred heifers fed with two tannins sources

The present research objective was to evaluate the performance and blood parameters of lactating cows fed with a diet of two tannin sources, based on sorghum (condensed tannin) with increasing concentrations of tannic acid (hydrolyzable tannin’s). Increasing levels of tannic acid in a sorghum-based diet for five Holstein/Zebu crossbred lactating cows were subject to a 5 × 5 Latin square experimental design. To assess the effect on cow intake, digestibility, milk production, and blood parameters. All cows received 9.87 kg/DM of corn silage as roughage and 6.38 kg of concentrate consisting of 2.58 kg/DM of ground sorghum 0.87 kg/DM of cornmeal 1.32 kg/DM of soybean bran 0.44 kg/DM of wheat bran 0.2 kg/ DM of urea and 0.18 kg/ DM of mineral mixture. Diet 1 (control) contained low-tannin sorghum and the other diets contained high-tannin sorghum. The levels of tannic acid added to the diets were established based on the quantity of condensed tannin in high-tannin sorghum. Thus, diets 2, 3, 4 and 5 were supplemented with 1.5g (13.%DM), 79.5g (2.6%DM), 157.5g (3.9%DM) and 235.5g (5.2%DM) of tannic acid, totalling 0.078, 0.156, 0.234 and 0.321 total tannin kg/day respectively, to assess the effect on microbial protein synthesis. The diets contained 35 kg of corn silage (roughage) and 6.40 kg of concentrate. The natural and dry matter intake did not significantly differ between groups, except for ether extract (EE) intake that significantly differed. The DM apparent digestibility, crude protein, EE, neutral detergent fiber, total carbohydrate, and non-fibrous carbohydrate did not differ (P &gt; 0.05) with the increase in dietary tannin supplementation. The GOT levels increased linearly. The blood glucose, triglyceride, and cholesterol (total, LDL and HDL) levels did not significantly differ. Hemoglobin showed a significant difference. No significant difference in urea, creatinine and uric acid occurred. Diets using two tannins sources supplementation caused no decrease in the dietary intake or digestibility in the animals. The GOT level changed significantly, showing linear behavior, however below the toxicity level, without any change in the other blood parameters. Milk production decreased with the increase in dietary tannin supplementation.

Effectiveness of Boiled Cherry Leaf (muntingia calabura L) Toward Ureum Creatinine Serum of Wistar Strain Mice with Acute RenalFailure Model

Renal failure is a clinical condition that is characterized by a decrease in kidney function with an indicator of changes in the levels of urea and creatinine. The purpose of this study is to determine the effectiveness of Boiled Cherry leaf (muntingia calabura L) on the reduction of ureum and creatinine levels. The objects in this study were 30 male Wistar strain rats aged 2-3 months with a weight of 180-200 grams. Rats were randomly grouped into 3 groups: the treatment group, positive control and negative control. The positive treatment and control group was induced gentamicin 0.3 cc IP / day for 7 days. Boiled water from 10 grams of cherry leaves (muntingia calabura) in 200 cc of boiling water to 100 cc was given as much as 3.6 cc orally for 7 days to the treatment group. Data were analyzed with SPSS version 24, One test ANOVA was performed to compare urea and creatinine levels. The results showed that there were significant differences in urea and creatinine levels between the treatment group and the positive control group (p &lt;0.05). Urea and creatinine values between the treatment group and the negative control group were not different (p = 0.06). As Conclusion , boiled cherry leaves (muntingia calabura) has an effect on the reduction of urea and creatinine serum in male wistar strain rats with acute renal failure models.

Kidney therapeutic potential of peptides derived from the bromelain hydrolysis of green peas protein.

Kidney disease is a global health problem that needs a solution to its therapy. In the previous study, we found that protein hydrolysate of green peas origin of Indonesia hydrolysed by bromelain (PHGPB) showed improve kidney function in cisplatin-induced nephropathy rats. In this study, we investigated the effect of PHGPB to obtain effective dose that exerts a therapeutic effect on chronic kidney disease (CKD) based on reducing urea and creatinine levels and to elucidate its mechanism of action. Two sets of experiments were conducted: (1) characteristics and proteomic profile of PHGPB, (2) in vivo test of PHGPB in gentamycin-induced Wistar rats, including urea and creatinine measurements, activities of antioxidant and kidney-related peptides (ANP, COX-1, and renin). PHGPB showed three bands under 10 kDa using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and contained 10 identified proteins using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Significant differences in urea and creatinine levels were found between all PHGPB treatments and positive controls (P<0.01). The lowest levels of urea and creatinine that were validated by high super oxide dismutase (SOD) activity and atrial natriuretic peptide (ANP) level were obtained in the 200 mg/day PHGPB treatment. However, the mean renin level was high and cyclooxygenase-1 (COX-1) level did not exceed positive and negative control levels. PHGPB at dose 200 mg/kgBW shows a potential CKD therapeutic effect that is dose-dependent. Higher PHGPB dose corresponds to better effect on kidney function by increasing antioxidant activity and ANP levels in gentamycin-induced Wistar rats.

Effect of Combined Heat killed Probiotic and Wheat Bran on Gastrointestinal Symptoms in Hemodialysis Children.

Background Gastrointestinal (GIT) disturbances are recorded in patients with end stage renal diseases (ESRD) frequently, killed probiotic was reported in to decrease GIT problems many other diseases ; So The aim of our study is to evaluate whether a combination of heat killed probiotic and wheat bran affect the presence and severity of gastrointestinal symptoms (GIS) in hemodialysis children Patients and methods Our study was Open label uncontrolled clinical trial conducted on 35 pediatric patients on regular hemodialysis for end stage renal disease. Every patient received one sachet of killed probiotic and wheat bran twice daily for two months. Assessment of GIT symptoms were done one month before administration of the drug, then follow them for two months during intervention then reassess the symptoms. Result We found that combined heat killed probiotic +wheat bran administration to hemodialysis children produced significant differences in urea, Hb and Po4 levels compared to baseline levels, in addition children produced highly significant decrease in all gastrointestinal symptoms (P<0.001) after 1 month, after 2 months in comparison to baseline. Conclusion We concluded that combination of heat killed probiotic and wheat bran decreases presence and severity of gastrointestinal symptoms (GIS) in hemodialysis children; thus we hypothysed that, our results could represent an important preliminary work that need further justification.

Perbedaan kadar ureum, natrium, kalium dan klorida pra dan pasca hemodialisa pada pasien dengan penyakit ginjal kronik

Background: Chronic Kidney Disease (CKD) is a progressive and irreversible damage to kidney function (GFR &lt; 60 ml / minute / 1.73 m2). The function of the kidneys is to maintain stability, electrolyte level, osmolarity of extracellular fluid and excrete products such as urea, uric acid, and creatinine. CKD disrupts electrolyte fluid balance and uremia, thus requiring renal replacement therapy in the form of dialysis or kidney transplantation. Different levels of urea, sodium, potassium, and chloride pre- and post-hemodialysis can be a consideration for the management of hemodialysis in CKD patients. This study aimed to determine the difference in urea, sodium, potassium, and chloride pre- and post-hemodialysis in CKD patients.Method: This was a cross-sectional analytical observational study of pre- and post hemodialysis conducted from September to October 2018. Normally distributed data were analyzed using the paired t-test, while data that were not normally distributed were analyzed using the Wilcoxon test. It was considered significant when the p-value was &lt; 0.05.Results: There was a total of 50 patients consisting of 30 males (60.0%) and 20 females (40.0%). The mean age of the patients was 51.10 ± 7.48 years. The level of pre-hemodialysis urea (161.96 ± 53.80 mg / dL) was significantly different from post-hemodialysis (120.70 ± 40.84 mg / dL). The level of pre-hemodialysis sodium (134.5 mmol / L) was significantly different from post-hemodialysis (140 mmol / L). The level of pre-hemodialysis potassium (5.6 mmol / L) was significantly different from post-hemodialysis (4.6 mmol / L). The level of pre-hemodialysis chloride (100 mmol / L) was significantly different from post-hemodialysis (96 mmol / L). Conclusion: There was a significant difference in urea, sodium, potassium, and chloride between pre- and post-hemodialysis (p &lt; 0.05).

Thyroid status in premenopausal and postmenopausal women – A biochemical study on insulin resistance in non obese, overweight and obese type 2 diabetics
