    Uric acid produced by xanthine oxidase (also a source of superoxide radicals) has been known to increase in hypertensive patients. In this study we evaluated the possible involvement of uric acid and xanthine oxidase in the pathogenesis of hypertension by examining their association with mean arterial pressure (MAP) and factors related to blood pressure. These factors include age, quetelet index (weight/height2), cholesterol, creatinine, calcium (Ca), magnesium (Mg), sodium (Na), potassium (K) and urea. Fifty Two (male-19, female-33) normal healthy individuals were studied. Correlation studies of demographic variables showed that age was positively correlated with MAP [r = 0.309, p = 0.026] and cholesterol [r = 0.503, p = 0.000] while quetelet index was positively correlated with age [r = 422, p = 0.000] MAP [r = 0.331, p = 0.016] and xanthine oxidase [r = 0.331, p = 0.016]. MAP was positively correlated with uric acid [r = 0.511, p = 0.000], cholesterol [r = 0.492, p = 0.000] and xanthine oxidase enzyme activity [r = 0.388, p = 0.004] and negatively correlated with plasma calcium [r = 0.603, p = 0.000]. Correlation studies of measured parameters with uric acid and xanthine oxidase showed that uric acid was positively correlated with creatinine [r = 0.627, p = 0.000], plasma magnesium [r 0.442, p = 0.001] and negatively correlated with plasma calcium [r = 0.546, p = 0.000] while xanthine oxidase was negatively correlated with plasma calcium [r = -0.404, p = 0.003] and plasma sodium [r = -0.288, p = 0.038]. Stepwise multiple regression with MAP as dependent variable showed that 65% of total variability of blood pressure can be accounted for by plasma calcium, cholesterol, creatinine, plasma K, plasma Na, uric acid and xanthine oxidase in order of increasing R2 [xanthine oxidase: T-value = 3.26, R2 = 0.653]. It can be concluded that in normotensive subjects, uric acid and xanthine oxidase have significant association with blood pressure and thus are one of the many factors which are involved in the cause or effect of hypertension.

    PMID: 27130746
    Extra-adrenal /retroperitoneal paraganglioma is a rare cause of hypertension in young with increased incidence of metastasis as compared to adrenal pheochromocytoma. We present a case of a young female with history of headache, nausea/vomiting, palpitations, uncontrolled hypertension, heat intolerance and diaphoresis. The 24-hour urine catecholamine levels were elevated. Clinical diagnosis of pheochromocytoma was made and further evaluation with Computed Tomography (CT) scan of the adrenals revealed extradrenal para-aortic retroperitoneal mass in keeping with paraganglioma. Gallium-68 DOTATE positron emission tomography-CT scan (PET-CT) confirmed the diagnosis without evidence of metastatic foci.

    PMID: 2569423
    Transient blindness associated with pregnancy induced hypertension without neurological symptoms is a rare phenomenon. The blindness in these cases is postulated to be of "cortical blindness". Two such cases occurring immediately after childbirth are presented. The ophthalmic manifestations of this complication of pregnancy induced hypertension and the importance of an urgent evaluation are discussed.

  5. Fulltext The use of endoscopic ultrasound and intravenous secretin as an investigative tool to aid diagnosis in pancreatic sphincter hypertension
    Suresh RL, Guinane M, Ainley C
    Med J Malaysia, 2001 Sep;56(3):382-5.
    PMID: 11732088
    Pancreatic sphincter hypertension (PSH) is one of the causes of recurrent pancreatitis. The diagnosis can be established by direct measurement of pancreatic sphincter pressures at pancreatic sphincter manometry. This procedure is not without risks, and in cases with PSH, it certainly carries a higher risk of post procedure pancreatitis. The treatment of this disorder is pancreatic sphincterotomy, which on its own carries risk of acute pancreatitis. Therefore it is important to establish the diagnosis reliably before undertaking this procedure. In order to overcome the false positive readings that are possible in sphincter manometry, we proposed to use secretin stimulated endoscopic ultrasound (SSEUS) to measure pancreatic ductal response as an adjunctive method to aid and supplement the diagnosis. Here we describe 3 cases in which this was carried out to optimal effect.

    Thermally oxidized oil generates reactive oxygen species that have been implicated in several pathological processes including hypertension. This study was to ascertain the role of inflammation in the blood pressure raising effect of heated soybean oil in rats. Male Sprague-Dawley rats were divided into four groups and were fed with the following diets, respectively, for 6 months: basal diet (control); fresh soybean oil (FSO); five-time-heated soybean oil (5HSO); or 10-time-heated soybean oil (10HSO). Blood pressure was measured at baseline and monthly using tail-cuff method. Plasma prostacyclin (PGI(2) ) and thromboxane A(2) (TXA(2) ) were measured prior to treatment and at the end of the study. After six months, the rats were sacrificed, and the aortic arches were dissected for morphometric and immunohistochemical analyses. Blood pressure was increased significantly in the 5HSO and 10HSO groups. The blood pressure was maintained throughout the study in rats fed FSO. The aortae in the 5HSO and 10HSO groups showed significantly increased aortic wall thickness, area and circumferential wall tension. 5HSO and 10HSO diets significantly increased plasma TXA(2) /PGI(2) ratio. Endothelial VCAM-1 and ICAM-1 were significantly increased in 5HSO, as well as LOX-1 in 10HSO groups. In conclusion, prolonged consumption of repeatedly heated soybean oil causes blood pressure elevation, which may be attributed to inflammation.

  7. Fulltext The improvement of hypertension by probiotics: effects on cholesterol, diabetes, renin, and phytoestrogens
    Lye HS, Kuan CY, Ewe JA, Fung WY, Liong MT
    Int J Mol Sci, 2009 Sep;10(9):3755-75.
    PMID: 19865517 DOI: 10.3390/ijms10093755
    Probiotics are live organisms that are primarily used to improve gastrointestinal disorders such as diarrhea, irritable bowel syndrome, constipation, lactose intolerance, and to inhibit the excessive proliferation of pathogenic intestinal bacteria. However, recent studies have suggested that probiotics could have beneficial effects beyond gastrointestinal health, as they were found to improve certain metabolic disorders such as hypertension. Hypertension is caused by various factors and the predominant causes include an increase in cholesterol levels, incidence of diabetes, inconsistent modulation of renin and imbalanced sexual hormones. This review discusses the antihypertensive roles of probiotics via the improvement and/or treatment of lipid profiles, modulation of insulin resistance and sensitivity, the modulation of renin levels and also the conversion of bioactive phytoestrogens as an alternative replacement of sexual hormones such as estrogen and progesterone.

  8. The effects of tempol on renal function and hemodynamics in cyclosporine-induced renal insufficiency rats
    Chia TY, Sattar MA, Abdulla MH, Rathore HA, Ahmad Fu, Kaur G, et al.
    Ren Fail, 2013 Aug;35(7):978-88.
    PMID: 23822648 DOI: 10.3109/0886022X.2013.809563
    This study investigated the effects of tempol, a superoxide dismutase (SOD) mimetic and L-NAME, a nitric oxide (NO) synthase inhibitor on the renal function and hemodynamics in cyclosporine A (CsA) induced renal insufficiency rats. Male Sprague-Dawley rats were treated with either vehicle (C), tempol (T, 1 mmol/L in drinking fluid), L-NAME (L, 1 mmol/L in drinking fluid), CsA (Cs, 25 mg/kg/day via gavage), CsA plus tempol (TCs), CsA plus L-NAME (LCs) or CsA plus a combination of tempol and L-NAME (TLCs) for 21 consecutive days. At the end of treatment regimen, the renal responses to noradrenaline (NA), phenylephrine (PE), methoxamine and angiotensin II (Ang II) were determined. Cs and LCs rats had lower creatinine clearance (0.7 ± 0.1 and 0.6 ± 0.5 vs. 1.3 ± 0.2 mL/min/kg) and fractional excretion of sodium (0.12 ± 0.02 and 0.17 ± 0.01 vs. 0.67 ± 0.04%) but higher systolic blood pressure (145 ± 2 and 178 ± 4 vs. 116 ± 2) compared to the control (all p

    Eur J Nutr, 2011 Jun;50(4):251-60.
    PMID: 20882287 DOI: 10.1007/s00394-010-0133-8
    PURPOSE: Fructose feeding induces a moderate increase in blood pressure, insulin resistance, and hyperinsulinemia. This study investigated the role of α(1B)-adrenoceptor subtype in the control of renal hemodynamic responses to exogenously administered angiotensin II (Ang II) and a set of adrenergic agonists in a model of high fructose-fed rats.
    METHODS: Sprague-Dawley rats were fed for 8 weeks with 20% fructose in drinking water (FFR). The renal cortical vasoconstriction to noradrenaline (NA), phenylephrine (PE), methoxamine (ME) and Ang II in the presence and absence of chloroethylclonidine (CEC) (α(1B)-adrenoceptor antagonist) was determined. Data, mean ± SEM or SD were subjected to ANOVA with significance at p

  10. Study of low salt diet in hypertensive patients with chronic kidney disease
    Koh KH, Wei-Soon LH, Jun L, Lui-Sian LN, Hui-Hong CT
    Med J Malaysia, 2018 12;73(6):376-381.
    PMID: 30647207
    INTRODUCTION: The efficacy of blood pressure (BP) reduction with salt restriction in CKD subjects and its sustainability is not well established.

    METHODS: We enrolled 75 hypertensive patients with CKD into one-month salt restricting diet. 24-hour urinary sodium and potassium was measured to verify their salt intake followed by 1½ year follow-up.

    RESULTS: Their creatinine clearance was 43 ± standard deviation 33ml/min/1.73m2. Urinary Na excretion (24HUNa) was 173±129mmol/day, reducing to 148±81 by 31±6 day. Mean, systolic and diastolic BP (MBP, SBP, DBP) were reduced from 102±9 to 97±11 (p<0.001), 148±10 to 139±16 (p<0.001), 78±12 to 75±12 mmHg (p=0.012) respectively. Moderate correlations were shown between reductions in 24-hour urinary Na and MBP, SBP, DBP: r=0.366, 0.260, 0.365; p=0.001, 0.025, 0.001; whereas 24-hour urinary Na-K ratio showed mild correlation. Subjects have some tendency to drift back to previous Na intake profile in follow-up and thus repetitive education is necessary. In subanalysis, 34 subjects with baseline 24HUNa >150 mmol/day, benefited significantly with MBP, SBP, DBP reduction from 102±9 to 95±9 (p=0.001), 146±10 to 135±14 mmHg (p=0.001), 80±11 to 75±11 mmHg (p=0.002) in line with 24HUNa reduction from 253±154 to 163±87mmol/day (p=0.004) and urinary protein-creation ratio reduction from geometric mean of 95 to 65 g/mol. Thirty five subjects with 24HUNa reduction of >20mmol/day have significant reduction in MBP, SBP, DBP: -8 vs -2, -15 vs -4, -5 vs -2 mmHg (p=0.027, 0.006, 0.218) and urinary protein-creatinine ratio: -82 vs 2g/mol (p=0.030) compared to the other forty subjects.

    CONCLUSION: Quantification of 24-hour urinary Na helps in predicting potential antihypertensive effect with dietary salt reduction of CKD subjects. Salt restriction reduces BP especially in patients with estimated daily sodium intake of >150mmol/day. Reduction in sodium intake beyond 20mmol/day reduced both BP and proteinuria.

    PMID: 30334968 DOI: 10.1097/MD.0000000000012787
    The aims of this study were to determine damage index in systemic lupus erythematosus (SLE) patients based on Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (SDI) and to determine the laboratory and clinico-demographic factors affecting SDI.This is a retrospective cohort study of 94 SLE patients attending rheumatology clinics in 2 local hospitals in Kelantan, Malaysia. The patients were divided into 2 groups based on SDI score assigned by the attending physician, 0 (without damage) or ≥1 (with damage). Newly diagnosed SLE patients with disease duration less than 6 months were excluded.A total of 45 (47.9%) SLE patients showed damage by SDI score. Majority of the subjects had neuropsychiatric damages (21/94; 22.3%) followed by skin (12/94; 12.8%) and musculoskeletal (6/94; 6.4%) damage. SDI score was significantly associated with higher disease duration (6.2 ± 6.57 years vs 4.5 ± 3.7 years; P = .018), lower prednisolone dose (8.74 ± 10.89 mg vs 4.89 ± 3.81 mg; P

  12. Secondary hypertension: a condition not to be missed
    Sukor N
    Postgrad Med J, 2011 Oct;87(1032):706-13.
    PMID: 21746730 DOI: 10.1136/pgmj.2011.118661
    Hypertension is a chronic disorder which often entails debilitating cardiovascular and renal complications. Hypertension mostly arises as a complex quantitative trait that is affected by varying combinations of genetic and environmental factors. Secondary hypertension has been encountered with increasing frequency. The common causes of secondary hypertension include renal parenchymal disease, renal artery stenosis, primary aldosteronism, phaeochromocytoma, and Cushing's syndrome. The detection of a secondary cause is of the utmost importance because it provides an opportunity to convert an incurable disease into a potentially curable one. Early identification and treatment will provide a better opportunity for cure, prevent target organ damage, reduce socioeconomic burden and health expenditure associated with drug costs, and improve patients' quality of life. Hence, it is a condition not to be missed.

    PMID: 20514927
    Obesity is intimately associated with hypertension; increases in blood pressure are closely related to the magnitude of weight gain. The present study aims to determine whether the excitatory amino acid input to rostral ventrolateral medulla (RVLM) contributes to elevated blood pressure in rats with diet-induced obesity. Male Sprague-Dawley rats weighing 280 to 300 grams were fed with a low-fat diet (10% kcal from fat) or moderately high-fat diet (32% kcal from fat) for 16 weeks. At week 16, rats on the moderate high-fat diet were segregated into obesity-prone and obesity-resistant rats based on body weight distribution. Baseline mean arterial pressure (MAP) was significantly higher in obesity-prone rats as compared to obesity-resistant and rats on a low-fat diet. Bilateral injection of kynurenic acid (KYN) (40 nM) into the RVLM of the obesity-prone rats reduced MAP to levels significantly different from those observed in rats on a low-fat diet and obesity-resistant rats (no change in MAP). At a lower concentration (4 nM), KYN injection did not produce any change in MAP in any group. The results obtained suggest that excitatory amino acid input to the RVLM does contribute to the development of hypertension in rats with diet-induced obesity.

  14. Fulltext Risk factors for proteinuria in a large, multiracial, southeast Asian population
    Ramirez SP, McClellan W, Port FK, Hsu SI
    J Am Soc Nephrol, 2002 Jul;13(7):1907-17.
    PMID: 12089388 DOI: 10.1097/01.asn.0000018406.20282.c8
    The factors associated with proteinuria were examined in a large multiracial Asian population participating in a screening program aimed at the early detection of renal disease. Of 213,873 adults who participated, 189,117 with complete data were included. Malay race, increasing age, both extremes of body mass index (BMI), self-reported family history of kidney disease (FKD), and higher systolic and diastolic BP measurements (even at levels classified as being within the normal range) were independently associated with dipstick-positive proteinuria. The odds ratios (OR) for proteinuria increased progressively with age. There was a J-shaped relationship between BMI and proteinuria (OR of 1.3, 1.00, 1.3, 1.6, and 2.5 for BMI of < or =18.00, 23.00 to 24.99, 25.00 to 27.49, 27.50 to 29.99, and > or =30.00 kg/m(2), respectively, compared with BMI of 18.01 to 22.99 kg/m(2)). OR for proteinuria according to systolic and diastolic BP were significantly increased beginning at levels of 110 and 90 mmHg, respectively. In addition, the Malay race was associated with a significantly higher OR for proteinuria, compared with the Chinese race (OR of 1.3). Finally, FKD was significantly associated with proteinuria (OR of 1.7), whereas a family history of diabetes mellitus and a family history of hypertension were not. When family histories were analyzed by clustering, isolated FKD remained a significant determinant of proteinuria and the magnitude of the effect was not significantly different from that observed in the presence of a coexisting family history of diabetes mellitus or hypertension. This is the first study to evaluate factors associated with proteinuria in an Asian population. The epidemiologic study of renal disease in this population suggests that risk factors for renal disease might differ significantly among racial groups.

    Virgin coconut oil, rich in antioxidants, was shown to attenuate hypertension. This study aimed to investigate the effects of virgin coconut oil on blood pressure and related parameters in kidneys in rats fed with 5-times-heated palm oil (5HPO). Thirty-two male Sprague-Dawley rats were divided into 4 groups. Two groups were fed 5HPO (15%) diet and the second group was also given virgin coconut oil (1.42 mL/kg, oral) daily for 16 weeks. The other 2 groups were given basal diet without (control) and with virgin coconut oil. Systolic blood pressure was measured pre- and post-treatment. After 16 weeks, the rats were sacrificed and kidneys were harvested. Dietary 5HPO increased blood pressure, renal thiobarbituric acid reactive substance (TBARS), and nitric oxide contents, but decreased heme oxygenase activity. Virgin coconut oil prevented increase in 5HPO-induced blood pressure and renal nitric oxide content as well as the decrease in renal heme oxygenase activity. The virgin coconut oil also reduced the elevation of renal TBARS induced by the heated oil. However, neither dietary 5HPO nor virgin coconut oil affected renal histomorphometry. In conclusion, virgin coconut oil has a potential to reduce the development of hypertension and renal injury induced by dietary heated oil, possibly via its antioxidant protective effects on the kidneys.

  17. Fulltext Renin-angiotensin-aldosterone system antagonism and polycystic kidney disease progression
    Hian CK, Lee CL, Thomas W
    Nephron, 2016;134(2):59-63.
    PMID: 27476173 DOI: 10.1159/000448296
    Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a systemic disease characterised by the formation of multiple renal cysts that adversely affect renal function. ADPKD shows significant progression with age when complications due to hypertension are most significant. The activation of the renin-angiotensin-aldosterone system (RAAS) occurs in progressive kidney disease leading to hypertension. The RAAS system may also contribute to ADPKD progression by stimulating signalling pathways in the renal cyst cells to promote growth and deregulate epithelial transport. This mini review focuses on the contribution of the RAAS system to renal cyst enlargement and the potential for antagonists of the RAAS system to suppress cyst enlargement as well as control ADPKD-associated hypertension.

  18. Purinergic P2Y6 receptors: A new therapeutic target of age-dependent hypertension
    Sunggip C, Nishimura A, Shimoda K, Numaga-Tomita T, Tsuda M, Nishida M
    Pharmacol Res, 2017 Jun;120:51-59.
    PMID: 28336370 DOI: 10.1016/j.phrs.2017.03.013
    Aging has a remarkable effect on cardiovascular homeostasis and it is known as the major non-modifiable risk factor in the development of hypertension. Medications targeting sympathetic nerve system and/or renin-angiotensin-aldosterone system are widely accepted as a powerful therapeutic strategy to improve hypertension, although the control rates remain unsatisfactory especially in the elder patients with hypertension. Purinergic receptors, activated by adenine, uridine nucleotides and nucleotide sugars, play pivotal roles in many biological processes, including platelet aggregation, neurotransmission and hormone release, and regulation of cardiovascular contractility. Since clopidogrel, a selective inhibitor of G protein-coupled purinergic P2Y12 receptor (P2Y12R), achieved clinical success as an anti-platelet drug, P2YRs has been attracted more attention as new therapeutic targets of cardiovascular diseases. We have revealed that UDP-responsive P2Y6R promoted angiotensin type 1 receptor (AT1R)-stimulated vascular remodeling in mice, in an age-dependent manner. Moreover, the age-related formation of heterodimer between AT1R and P2Y6R was disrupted by MRS2578, a P2Y6R-selective inhibitor. These findings suggest that P2Y6R is a therapeutic target to prevent age-related hypertension.

    Primary aldosteronism is now thought to be the commonest potentially curable and specifically treatable form of hypertension. The detection of primary aldosteronism is of utmost importance not only because it provides an opportunity for a targeted treatment, but also because it has been demonstrated that patients with primary aldosteronism are more prone to cardiovascular events and target organ damage than essential hypertensives. Normalization of blood pressure and hypokalemia should not be the only goal of treatment. Normalization of circulating aldosterone or mineralocorticoid blockade is necessary to prevent aldosterone-induced tissue damage that occurs independent of blood pressure. This review will focus on the current understanding and comprehensive management review of primary aldosteronism, highlighting the new evidence that has become recently available.

  20. Fulltext Prevalence of hypertension among Chinese elderly and its relationship to behavioural and nutritional factors
    Teo GS, Idris MN
    Med J Malaysia, 1996 Mar;51(1):33-40.
    PMID: 10967977
    A cross-sectional study was carried out to determine the prevalence of hypertension in the Chinese elderly and to examine its relationship with various behavioural and nutritional risk factors. This study involved 243 Chinese aged 55 years and older in 2 randomly selected Chinese Villages in Seberang Prai Tengah, Penang. The study included an interview, anthropometric assessment and blood pressure measurement. The prevalence of hypertension was 48.1% and out of this, 65 (55.6%) were on anti-hypertensive treatment. There was a significant rise in the prevalence with age. Hypertension was found to be inversely related to per capita income and physical activity (p < 0.05). Hypertension was significantly more common in smokers than non-smokers. Alcohol intake in the elderly was low and not related to hypertension. Obesity was significantly associated with hypertension only among the elderly aged 55-64 years. The dietary intake of sodium, potassium and calcium did not differ significantly between the hypertensive and normotensive elderly.
