    Urine output provides a rapid estimate for kidney function, and its use has been incorporated in the diagnosis of acute kidney injury. However, not many studies had validated its use compared to the plasma creatinine. It has been showed that the ideal urine output threshold for prediction of death or the need for dialysis was 0.3 ml/kg/h. We aim to assess this threshold in our local ICU population.

    Vanillin is useful as anti-sickle cell anemia, anti-mutagen and anti-bacteria agent. However, vanillin must be administered at high concentration and cannot be oxidized by the upper gastrointestinal track of patients to be medically effective. In this study, we assessed the toxic effect of vanillin when administered in an un-oxidized form at high concentrations (150 and 300 mg/kg) via oral and intra-peritoneal injection. It was found that 300 mg/kg vanillin injection caused the rats to be unconscious without exerting any toxic effect on blood cells, kidney and liver. Besides, it showed blood protective property. Further analysis with GenomeLab GeXP genetic system on brain tissues showed that the expression of most xenobiotic metabolism, cell progression, tumor suppressor, DNA damage and inflammation genes were maintained at normal level. However, the expression of a few xenobiotic metabolism, cell cycle arrest and apoptosis genes were up-regulated by 5% ethanol injection. Nevertheless, when 5% ethanol was injected with the presence of vanillin, the expression was back to normal level. It is postulated that vanillin might have neuro-protective property. In conclusion, vanillin is not toxic at high concentration in both oral and intra-peritoneal injection and could provide blood and brain protective properties.

  3. The effect of enalapril on tyramine induced changes in renal function in man
    Rahman AR, Lang CC, Struthers AD
    Int J Clin Pharmacol Ther, 1995 Jul;33(7):404-9.
    PMID: 7582398
    Increasing animal evidence support an important facilitatory interaction between angiotensin II and norepinephrine within the kidney. This angiotensin II/norepinephrine interaction was investigated in man by examining the effect of enalapril pretreatment (5 mg for 5 days) on the renal response to a low non-pressor dose of intravenous tyramine 4 micrograms/kg/min for 120 min in 8 healthy subjects undergoing water diuresis. Tyramine is an indirect sympathomimetic agent which causes neuronal release of norepinephrine. Enalapril and tyramine, alone and in combination, had no effect on glomerular filtration, effective renal plasma flow or sodium excretion. Tyramine caused a significant increase in urinary flow rate (p < 0.05) but this was not influenced by enalapril pretreatment. The lack of effect of enalapril on the renal response to tyramine contrasts with a previous study which examined the effect of enalapril on the renal response to circulating norepinephrine. This may suggest that enalapril affect renal function only when there is renal vasoconstriction (as with norepinephrine) and not when renal blood flow is unchanged (as with tyramine).

    Augmented renal clearance (ARC) refers to increased solute elimination by the kidneys. ARC has considerable implications for altered drug concentrations. The aims of this study were to describe the prevalence of ARC in a select cohort of patients admitted to a Malaysian intensive care unit (ICU) and to compare measured and calculated creatinine clearances in this group. Patients with an expected ICU stay of <24 hours plus an admission serum creatinine concentration <120 µmol/l, were enrolled from May to July 2013. Twenty-four hour urinary collections and serum creatinine concentrations were used to measure creatinine clearance. A total of 49 patients were included, with a median age of 34 years. Most study participants were male and admitted after trauma. Thirty-nine percent were found to have ARC. These patients were more commonly admitted in emergency (P=0.03), although no other covariants were identified as predicting ARC, likely due to the inclusion criteria and the study being under-powered. Significant imprecision was demonstrated when comparing calculated Cockcroft-Gault creatinine clearance (Crcl) and measured Crcl. Bias was larger in ARC patients, with Cockcroft-Gault Crcl being significantly lower than measured Crcl (P <0.01) and demonstrating poor correlation (rs=-0.04). In conclusion, critically ill patients with 'normal' serum creatinine concentrations have varied Crcl. Many are at risk of ARC, which may necessitate individualised drug dosing. Furthermore, significant bias and imprecision between calculated and measured Crcl exists, suggesting clinicians should carefully consider which method they employ in assessing renal function.

    PMID: 31726798 DOI: 10.3390/ijerph16224445
    Prolonged exposure to nicotine accelerates onset and progression of renal diseases in habitual cigarette smokers. Exposure to nicotine, either via active or passive smoking is strongly shown to enhance renal oxidative stress and augment kidney failure in various animal models. In this study, we investigated the effects of resveratrol supplementation on nicotine-induced kidney injury and oxidative stress in a rat model. Male Sprague-Dawley rats were given nicotine (0.6 mg/kg, i.p.) alone or in combination with either resveratrol (8 mg/kg, i.p.), or angiotensin II type I receptor blocker, irbesartan (10 mg/kg, p.o.) for 28 days. Upon completion of treatment, kidneys were investigated for changes in structure, kidney injury markers and oxidative stress. Administration of nicotine alone for 28 days resulted in significant renal impairment as shown by marked increase in plasma creatinine, blood urea nitrogen (BUN) and oxidative stress. Co-administration with resveratrol however successfully attenuated these changes, with a concomitant increase in renal antioxidants such as glutathione similar to the conventionally used angiotensin II receptor blocker, irbesartan. These data altogether suggest that targeting renal oxidative stress with resveratrol could alleviate nicotine-induced renal injury. Antioxidants may be clinically important for management of renal function in habitual smokers.

    PMID: 9561623
    Records of 183 patients with renal stones managed at Hospital Universiti Sains Malaysia between 1985 and 1995 were retrospectively evaluated. The commonest symptom was lumbar pain which may be associated with either frequency, blood stained urine or dysuria. One hundred and sixty-one patients (88%) had upper tract stones while the remainder had lower tract stones. Positive urine cultures were seen in 33 patients. The commonest organism isolated was Escherichia coli followed by Klebsiella aeruginosa and Staphylococcus aureus. Almost all of our patients had renal impairment at presentation and 70% of them progressed to chronic renal failure. In contrast to previous findings, the pattern of renal stone in this region is similar to that described in Western society. Its effect on renal function is serious and hence warrant special attention.

  8. Renal function overestimation in underweight and/or non-ambulatory patients
    Keshavarzi F
    Int J Clin Pharm, 2015 Oct;37(5):675-7.
    PMID: 26173939 DOI: 10.1007/s11096-015-0157-5
    Creatinine clearance estimation is widely used to evaluate the renal function of the patients in order to initiate or adjust the drugs dosage. However serum creatinine, as a muscle metabolism by-product, may not be a reliable parameter in underweight and/or non-ambulatory patients, such as geriatric, acquired immunodeficiency syndrome patients and bed-confined and cachexic cases. To avoid overestimation of the renal function in those patients, serum cystatin C can be considered as a sensitive and accurate alternative for serum creatinine.

    Phytother Res, 2014 Oct;28(10):1456-60.
    PMID: 24638976 DOI: 10.1002/ptr.5147
    Carum carvi L. (Apiaceae) is known as caraway, and its derivatives find wide medicinal use for health purposes, including for gastrointestinal problems and obesity. Since there is inconsistency among the reports on the safety of this plant in humans, this research was aimed at assessing the safety of a characterized caraway aqueous extract (CAE) in a randomized, triple-blind, placebo-controlled study. Seventy, overweight and obese, healthy women were randomly assigned into placebo (n = 35) and plant extract (n = 35) groups. Participants received either 30 ml/day of CAE or placebo. Subjects were examined at baseline and after 12 weeks for changes in heart rate, blood pressure, urine test, 25-item blood chemistries, and general health status. No significant changes of blood pressure, heart rate, urine specific gravity, and serum blood tests were observed between the two groups before and after treatment. However, in the complete blood count test, red blood cell levels were significantly (p

  10. Plasma asymmetric dimethylarginine and its association with some of cardiovascular disease risk factors in chronic kidney disease
    Quoc Hoang TA, Tam V, Thang HV
    Med J Malaysia, 2019 Jun;74(3):209-214.
    PMID: 31256175
    INTRODUCTION: Chronic kidney disease (CKD) usually has increase of asymmetric dimethylarginine (ADMA) levels. ADMA is a cardiovascular disease (CVD) risk factor and its elevation associated with other CVD risk factors at CKD leads to increasing risk of death. In this article, we aimed to identify levels and elevation proportion of plasma ADMA in CKD as well as association between ADMA with CVD risk factors.

    METHODS: This cross-sectional study was performed at Hue Central Hospital from 2012-2016 on 176 CKD and 64 control subjects. ADMA levels were measured by using the enzyme linked immunosorbent assay (ELISA) method.

    RESULTS: Mean ADMA level was markedly higher (p<0.001) in all patients combined (0.73±0.24μmol/L) than in control subjects (0.47±0.13μmol/L). Mean ADMA levels in advanced kidney disease were higher than control subjects. ADMA levels correlated inversely and relatively strictly to estimated glomerular filtration rate (eGFR) (r = -0.689; p<0.001), haemoglobin (r = -0.525; p<0.001) and haematocrit (r = - 0.491; p<0.001); correlated favourably and relatively strictly to serum creatinine (r = 0.569; p<0.001) and serum urea (r = 0.642; p<0.001). ADMA elevation was predicted simultaneously by eGFR<60 mL/min/1.73m2 (p<0.001), anaemia (p=0.002), body mass index (BMI) (p=0.011) and high sensitivity C-reactive protein (hs-CRP) (p=0.041). Cutoff of ≥0.68μmol/L, ADMA levels predict reduction of eGFR<60 mL/min/1.73m2, sensitivity of 86.9 %, specificity of 82.6%, area under ROC 92.4% (95%CI: 88.6-96.1%).

    Paracetamol (PCM) is a well-known drug widely used for its analgesic and antipyretic properties. PCM is generally considered as safe but overdose of PCM can cause nephrotoxicity. Traditionally, herbs have been used for the treatment of drug or toxin-induced renal disorders and numerous medicinal plants were tested for nephroprotection effect in PCM-induced nephrotoxicity model. The aim of the present study was to evaluate the protective effect of the herbal extract Eurycoma longifolia (EL) against PCM-induced nephrotoxicity rat model. Forty Wistar rats were randomly divided into five groups of eight rats each: control (vehicle 10 ml/kg), PCM alone (200 mg/kg PCM), EL 100 (EL 100 mg/kg+200 mg/kg PCM), EL 200 (EL 200 mg/kg+200 mg/kg PCM), and EL 400 (EL 400 mg/kg+200 mg/kg PCM). All animals from control group received vehicle daily and animals from groups PCM alone, EL 100, EL 200, and EL 400 received repeated dose of PCM and the assigned treatment of EL daily for a period of 14 days. On the 15th day, serum creatinine, blood urea nitrogen, protein, and albumin were measured in blood and creatinine clearance was measured in urine collected over 24 hours. Kidney sections of all experimental groups underwent histopathological analysis. There was a significant (p<0.05) increase in serum creatinine and blood urea levels in the PCM alone group compared to the treatment groups due to nephrotoxicity. In the treatment groups, there was a dose-dependent protection against PCM-induced changes observed in serum total protein, albumin, urea, and creatinine. Significant (p<0.05) drop was seen in serum creatinine and blood urea content in EL 200 and EL 400 groups. Creatinine clearance significantly increased for EL 200 (p<0.01) and EL 400 (p < 0.001) groups. Serum total protein and serum albumin content were significantly increased (p<0.05) in EL 200 and EL 400 groups compared to PCM alone group. Histopathological examination (H&E staining) of the rat kidneys revealed severe degeneration in the PCM alone group, while there was evidence of significant dose-dependent protection in the treatment groups against PCM-induced changes. The serum and urine biochemical results and histopathology analysis of the kidney indicate the nephroprotective potential of EL extract against PCM-induced nephrotoxicity.

    BMC Nephrol, 2017 Dec 13;18(1):363.
    PMID: 29237422 DOI: 10.1186/s12882-017-0776-2
    BACKGROUND: Accurate measurement of renal function is important: however, radiolabelled gold standard measurement of GFR is highly expensive and can only be used on a very limited scale. We aim to compare the performance of Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equations in the multi-ethnic population attending University Malaya Medical Centre (UMMC).
    METHODS: This is a cross-sectional study recruiting patients, who attend UMMC Nephrology clinics on voluntary basis. 51-Chromium EDTA (51Cr-EDTA) plasma level was used to measure the reference GFR. The serum creatinine was determined by IDMS reference modified Jaffe kinetic assay (CrJaffe). The predictive capabilities of MDRD and CKD-EPI based equations were calculated. Data was analysed using SPSS version 20 and correlation, bias, precision and accuracy were determined.
    RESULTS: A total of 113 subjects with mean age of 58.12 ± 14.76 years and BMI of 25.99 ± 4.29 kg/m2 were recruited. The mean reference GFR was 66.98 ± 40.65 ml/min/1.73m2, while the estimated GFR based on MDRD and CKD-EPI formula were 62.17 ± 40.40, and 60.44 ± 34.59, respectively. Both MDRD and CKD-EPI were well-correlated with reference GFR (0.806 and 0.867 respectively) and statistically significant with p

    PMID: 28674665 DOI: 10.7717/peerj.3513
    BACKGROUND: Osteoprotegerin (OPG) is used for the systemic treatment of bone diseases, although it has many side effects. The aim of this study was to investigate a newly formulated OPG-chitosan gel for local application to repair bone defects. Recent studies have reported that immunodetection of osteopontin (OPN) and osteocalcin (OC) can be used to characterise osteogenesis and new bone formation.

    METHODS: The osteogenic potential of the OPG-chitosan gel was evaluated in rabbits. Critical-sized defects were created in the calvarial bone, which were either left unfilled (control; group I), or filled with chitosan gel (group II) or OPG-chitosan gel (group III), with rabbits sacrificed at 6 and 12 weeks. Bone samples from the surgical area were decalcified and treated with routine histological and immunohistochemical protocols using OC, OPN, and cathepsin K (osteoclast marker) antibodies. The toxicity of the OPG-chitosan gel was evaluated by biochemical assays (liver and kidney function tests).

    RESULTS: The mean bone growth in defects filled with the OPG-chitosan gel was significantly higher than those filled with the chitosan gel or the unfilled group (p functional tests indicated no signs of harmful systemic effects of treatment. In conclusion, the OPG-chitosan gel has many characteristics that make it suitable for bone repair and regeneration, highlighting its potential benefits for tissue engineering applications.

    Chlorine is shown to possess anti-gastric ulcer activity, since it can inactivate Helicobacter pylori, which is regarded as one of the most common risk factors for causing gastric problems. In the current study, the gastroprotective property of a novel dichloro-substituted Schiff base complex, 2, 2'- [-1, 2-cyclohexanediylbis(nitriloethylidyne)] bis(4-chlorophenol) (CNCP), against alcohol-induced gastric lesion in SD rats was assessed. SD rats were divided into four groups, i.e. normal, ulcer control, testing, and reference groups. Ulcer area, gastric wall mucus, and also gastric acidity of the animal stomachs were measured. In addition, antioxidant activity of CNCP was evaluated and its safe dose was identified. Immunohistochemistry staining was also carried to evaluate two important proteins, i.e. Bcl2-associated X protein (Bax) and heat shock protein 70 (HSP70). Moreover, the activities of super oxide dismutase and catalase, as well as the levels of prostaglandin E2 (PGE2) and malondialdehyde (MDA) were also measured. Antioxidant activity of CNCP was approved via the aforementioned experiments. Histological evaluations showed that the compound possesses stomach epithelial defense activity. Additionally, periodic acid-Schiff staining exhibited over-expression of HSP70 and down-expression of Bax protein in the CNCP-treated rats. Moreover, CNCP caused deceased MDA level and elevated PGE2 level, and at the same time increased the activities of the two enzymes.

    Preeclampsia patients have frequently been found to experience hyperuricaemia and this may result in poor outcomes compared to those with normal uric acid levels. This study aimed to determine the relationship of hyperuricaemia in pre-eclampsia patients with foetal and maternal outcomes. This prospective cohort study involved 79 patients in a tertiary centre from year 2016 to 2018. Blood samples were taken antenatally and at the 6th week, post-delivery for renal function including serum uric acid level. Our findings indicate that there was a higher incidence of poor maternal and foetal outcomes in the hyperuricaemia group than the normal uric acid group. Serum uric acid has been shown to be a significant predictor for low birth weight and premature delivery in preeclampsia patients. It was also found that there was a significant negative correlation between uric acid level and antenatal creatinine clearance (rs = -0.338, p = .002). The assessment of the serum uric acid level seems to be important to ensure better outcomes in patients with preeclampsia.Impact statementWhat is already known on this subject? Preeclampsia is a serious pregnancy-related complication and remains as one of the most important cause of maternal and foetal morbidity and mortality, affecting 2-8% in all pregnancy. Many studies have established the association between hyperuricaemia and preeclampsia. Besides, numerous studies have found that hyperuricaemia contributed to adverse maternal and foetal outcomes.What the results of this study add? There was a significant increase in adverse foetal and maternal outcomes in the hyperuricaemia group compared to the normal uric acid group. This study revealed that serum uric acid remains a significant predictor for low birth weight and premature delivery in preeclampsia patients.What the implications are of these findings for clinical practice and/or further research? Hyperuricaemia does not merely become an indicator for the severity of disease in preeclampsia patients but also indicates adverse foetal outcomes. Large population-based studies are required to establish the absolute maternal and foetal outcomes in patients with hyperuricaemia. Besides, further studies are recommended on long-term implication of hyperuricaemia which is not limited to only during antenatal period.

  18. Evaluation of the safety of heated vegetable oils containing 25% of polar compounds
    Ng, Tony Kock Wai
    Malaysian Journal of Medicine and Health Sciences, 2006;2(1):25-39.
    MyJurnal
    Introduction: The content of polar compounds (PC) and polymeric triglycerides build up in fried and recycled/reused oils and therefore, these undesirable components are often used as markers of deterioration in edible oil quality. Expert and authoritative agencies have recommended an upper limit of 25% for PC in fried/reused edible oils; beyond this level the oil is considered unsuitable for human consumption. The safety of recycled or repeatedly-heated oils is still very much a concern of both the health authorities and the general public.
    Objective: The present study evaluates the safety of long-tern consumption of heated vegetable oils containing 25% of PC on growth, effect on major body organs and reproduction outcome, using the Sprague-Dawley rat model.
    Methods: Refined, bleached and deodorised palm olein (PO) and partially hydrogenated soybean oil (HSBO) were repeatedly heated for 5 hours daily with no topping-up at Isoac until a polar compound (PC) content of25% was attained. Refined soybean oil was similarly heated up to 50% PC and used in the positive control diet. All five experimental oils, namely unheated PO (No PC), heated PO (25% PC), unheated HSBO (No PC), heated HSBO (25% PC), and positive control oil (50% PC) were separately incorporated at 30% energy (15% w/w) as the sole dietary fat into nutritionally-adequate purified diets. Each experimental diet was provided ad libitum to a different dietary group comprising 14 male and 20 female Swiss albino rats. After 13 weeks (90 days), 10 males were selected from each group and each male was paired with two females from the same dietary group for the reproductive study. After 4 weeks into the reproductive study (total of 17 weeks on the experimental diets), all 10 males in each group were sacrificed and the usual toxicity tests consisting of blood cell type counts, liver and kidney function tests, and examination (organ-to-body weight ratios and histology) of the liver, kidney, heart and spleen were performed.
    Results: The heated PO and HSBO diets were well-tolerated by the animals. However, these heated test oils inhibited growth marginally (p>0.05), enlarged the liver, kidney and heart, and markedly raised serum alkaline phosphatase (liver function test) compared to the unheated oils (p

    Aflatoxin is ubiquitously found in many foodstuffs and produced by Aspergillus species of fungi. Of many aflatoxin metabolites, AFB1 is classified by the International Agency for Research on Cancer (IARC) as group one carcinogen and linked to the development of hepatocellular carcinoma (HCC). The study on molecular biomarker of aflatoxin provides a better assessment on the extent of human exposure to aflatoxin. In Malaysia, the occurrences of aflatoxin-contaminated foods have been documented, but there is a lack of data on human exposure to aflatoxin. Hence, this study investigated the occurrence of AFB1-lysine adduct in serum samples and its association with liver and kidney functions. 5ml fasting blood samples were collected from seventy-one subjects (n=71) for the measurement of AFB1-lysine adduct, albumin, total bilirubin, AST (aspartate aminotransferase), ALT (alanine transaminase), ALP (alkaline phosphatase), GGT (gamma-glutamyl transpeptidase), creatinine and BUN (blood urea nitrogen). The AFB1-lysine adduct was detected in all serum samples (100% detection rate) with a mean of 6.85±3.20pg/mg albumin (range: 1.13-18.85pg/mg albumin). Male subjects (mean: 8.03±3.41pg/mg albumin) had significantly higher adduct levels than female subjects (mean: 5.64±2.46pg/mg albumin) (p<0.01). It was noteworthy that subjects with adduct levels greater than average (>6.85pg/mg albumin) had significantly elevated level of total bilirubin (p<0.01), GGT (p<0.05) and creatinine (p<0.01). Nevertheless, only the level of total bilirubin, (r=0.347, p-value=0.003) and creatinine (r=0.318, p-value=0.007) showed significant and positive correlation with the level of AFB1-lysine adduct. This study provides a valuable insight on human exposure to aflatoxin in Malaysia. Given that aflatoxin can pose serious problem to the health, intervention strategies should be implemented to limit/reduce human exposure to aflatoxin. Besides, a study with a big sample size should be warranted in order to assess aflatoxin exposure in the general population of Malaysia.

    Adapted automated peritoneal dialysis (aAPD), comprising a sequence of dwells with different durations and fill volumes, has been shown to enhance both ultrafiltration and solute clearance compared to standard peritoneal dialysis with constant time and volume dwells. The aim of this non-interventional study was to describe the different prescription patterns used in aAPD in clinical practice and to observe outcomes characterizing volume status, dialysis efficiency, and residual renal function over 1 year. Prevalent and incident, adult aAPD patients were recruited during routine clinic visits, and aAPD prescription, volume status, residual renal function and laboratory data were documented at baseline and every quarter thereafter for 1 year. Treatments were prescribed according to the nephrologist's medical judgement in accordance with each center's clinical routine. Of 180 recruited patients, 160 were analyzed. 27 different aAPD prescription patterns were identified. 79 patients (49.4%) received 2 small, short dwells followed by 3 long, large dwells. During follow-up, volume status changed only marginally, with visit mean values ranging between 1.59 (95% confidence interval: 1.19; 1.99) and 1.97 (1.33; 2.61) L. Urine output and creatinine clearance decreased significantly, accompanied by reductions in ultrafiltration and Kt/V. 25 patients (15.6%) received a renal transplant and 15 (9.4%) were changed to hemodialysis. Options for individualization offered by aAPD are actually used in practice for optimized treatment. Changes observed in renal function and dialysis efficiency measures reflect the natural course of chronic kidney disease. No safety events were observed during the study period.
