Trans-resveratrol was earlier shown to lower intraocular pressure (IOP) in rats; however, its mechanisms of action remain unclear. It has been shown to modulate adenosine receptor (AR) and TGF-β2 signaling, both of which play a role in regulating IOP. Hence, we investigated effects of trans-resveratrol on AR and TGF-β2 signaling. Steroid-induced ocular hypertensive (SIOH) rats were pretreated with A1AR, phospholipase C (PLC) and ERK1/2 inhibitors and were subsequently treated with single drop of trans-resveratrol. Metalloproteinases (MMP)-2 and -9 were measured in aqueous humor (AH). In another set of experiments, effect of trans-resveratrol on AH level of tissue plasminogen activator (tPA) and urokinase plasminogen activator (uPA) was determined after single and multiple drop administration in SIOH rats. Effect of trans-resveratrol on ARs expression, PLC and pERK1/2 activation and MMPs, tPA and uPA secretion was determined using human trabecular meshwork cells (HTMC). Further, effect of trans-resveratrol on TGF-β2 receptors, SMAD signaling molecules and uPA and tPA expression by HTMC was determined in the presence and absence of TGF-β2. Pretreatment with A1AR, PLC and ERK1/2 inhibitors antagonized the IOP lowering effect of trans-resveratrol and caused significant reduction in the AH level of MMP-2 in SIOH rats. Trans-resveratrol increased A1AR and A2AAR expression, cellular PLC, pERK1/2 levels and MMP-2, tPA and uPA secretion by HTMC. Additionally, it produced TGFβRI downregulation and SMAD 7 upregulation. In conclusion, IOP lowering effect of trans-resveratrol involves upregulation of A1AR expression, PLC and ERK1/2 activation and increased MMP-2 secretion. It downregulates TGFβRI and upregulates SMAD7 hence, inhibits TGF-β2 signaling.

Blood pressure lowering effect and vascular activity of Phyllanthus niruri extract: The role of NO/cGMP signaling pathway and β-adrenoceptor mediated relaxation of isolated aortic rings

Bello I, Usman NS, Dewa A, Abubakar K, Aminu N, Asmawi MZ, et al.

J Ethnopharmacol, 2020 Mar 25;250:112461.
PMID: 31830549 DOI: 10.1016/j.jep.2019.112461

ETHNOPHARMACOLOGICAL RELEVANCE: Phyllanthus niruri have a long history of use in the traditional treatment of various ailments including hypertension. Literature reports have indicated that it is a potent antihypertensive herbal medication used traditionally.
AIM OF THE STUDY: This study was carried out to investigate the antihypertensive and vasodilatory activity of four solvents extracts of P. niruri namely; petroleum ether (PEPN), chloroform (CLPN), methanol (MEPN) and water (WEPN), with the aim of elucidating the mechanism of action and identifying the phytochemical constituents.
MATERIALS AND METHODS: Male Spontaneous Hypertensive Rats (SHRs) were given oral gavage of P. niruri extract daily for two weeks and the blood pressure was recorded in vivo. We also determine the vasodilation effect of the extracts on rings of isolated thoracic aorta pre-contracted with phenylephrine (PE, 1 μM). Endothelium-intact or endothelium-denuded aorta rings were pre-incubated with various antagonists like 1H-[1,2,4] oxadiazolo-[4,3-a]quinoxalin-1-one (ODQ, 10 μM) and Methylene blue (MB 10 μM), sGC inhibitors; Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME, 10 μM) a nitric oxide synthase (NOS) inhibitor; atropine (10 μM), a cholinergic receptor blocker; indomethacin (10 μM), a cyclooxygenase inhibitor and various K+ channel blockers such as glibenclamide (10 μM) and tetraethyl ammonium (TEA 10 μM) for mechanism study.
RESULTS: SHRs receiving P. niruri extracts showed a significant decrease in their blood pressure (BP) when compared to the baseline value, with PEPN being more potent. The extracts (0.125-4 mg/mL) also induced vasorelaxation on endothelium-intact aorta rings. PEPN elicited the most potent maximum relaxation effect (Rmax). Mechanism assessment of PEPN showed that its relaxation effect is significantly suppressed in endothelium-denuded aorta rings. Pre-incubation of aorta rings with atropine, L-NAME, ODQ, indomethacin, and propranolol also significantly attenuated its relaxation effect. Conversely, incubation with TEA and glibenclamide did not show a significant effect on PEPN-induced relaxation.
CONCLUSION: This study indicates that the antihypertensive activity of P. niruri extract is mediated by vasoactive phytoconstituents that dilate the arterial wall via endothelium-dependent pathways and β-adrenoceptor activity which, in turn, cause vasorelaxation and reduce blood pressure.

PMID: 24729425 DOI: 10.1093/ije/dyu089

The Malaysian Cohort study was initiated in 2005 by the Malaysian government. The top-down approach to this population-based cohort study ensured the allocation of sufficient funding for the project which aimed to recruit 100,000 individuals aged 35-70 years. Participants were recruited from rural and urban areas as well as from various socioeconomic groups. The main objectives of the study were to identify risk factors, to study gene-environment interaction and to discover biomarkers for the early detection of cancers and other diseases. At recruitment, a questionnaire-based interview was conducted, biophysical measurements were performed and biospecimens were collected, processed and stored. Baseline investigations included fasting blood sugar, fasting lipid profile, renal profile and full blood count. From April 2006 to the end of September 2012 we recruited a total of 106,527 participants. The baseline prevalence data showed 16.6% participants with diabetes, 46.5% with hypertension, 44.9% with hypercholesterolaemia and 17.7% with obesity. The follow-up phase commenced in June 2013. This is the most comprehensive and biggest cohort study in Malaysia, and has become a valuable resource for epidemiological and biological research.

Parkia speciosa Hassk is a plant found abundantly in Southeast Asia region. Its seeds with or without pods and roots have been used in traditional medicine in this region to treat hypertension. Therefore, we aimed to investigate the potential effect of the plant empty pod extract on hypertension development and changes in heart induced by N(G)-nitro-l-arginine methyl ester (l-NAME) administration in rats. Twenty-four male Sprague Dawley rats were divided into four groups. Groups 1 to 3 were given l-NAME (25mg/kg, intraperitoneally) for 8 weeks. Groups 2 and 3 were also given Parkia speciosa empty pods methanolic extract (800mg/kg, orally) and nicardipine (3mg/kg, orally), concurrently with l-NAME. The last group served as the control. l-NAME reduced plasma nitric oxide level and therefore, increased systolic blood pressure, angiotensin-converting enzyme and NADPH oxidase activities as well as lipid peroxidation in the heart. Parkia speciosa extract and nicardipine treatments had significantly prevented the elevations of blood pressure, angiotensin-converting enzyme, NADPH oxidase activities and lipid peroxidation in the heart induced by the l-NAME. Parkia speciosa extract but not nicardipine prevented the reduction in plasma nitric oxide level caused by l-NAME. In conclusion, Parkia speciosa empty pods methanolic extract has a potential to prevent the development of hypertension possibly by preventing the loss of plasma nitric oxide, as well as has cardioprotective effects by reducing angiotensin-converting enzyme activity and oxidative stress in the heart in rats administered l-NAME.

PMID: 29084680

Consumption of corn oil for cooking purpose is gaining popularity. The present study examined the effect of heated corn oil on blood pressure and its possible mechanism in experimental rats. Thirty male Sprague-Dawley rats were randomly divided into 5 groups and were fed with the following diets, Group I was fed with basal diet only; whereas group II,III,IV and V were fed with basal diet fortified with 15% (w/w) either fresh, once-heated, five-times-heated or ten-times-heated corn oil, respectively for 16 weeks. Body weight, blood pressure were measured at baseline and weekly interval for 16 weeks. Inflammatory biomarkers which included soluble intracellular adhesion molecules (sICAM), soluble vascular adhesion molecules (sVCAM) and C reactive protein (CRP), were measured at baseline and the end of 16 weeks. The rats were sacrificed and thoracic aorta was taken for measurement of vascular reactivity. There was significant increase in the blood pressure in the groups fed with heated once, five-times (5HCO) and ten-times-heated corn oil (10-HCO) compared to the control. The increase in the blood pressure was associated with an increase in CRP, sICAM and sVCAM, reduction in vasodilatation response to acetylcholine and greater vasoconstriction response to phenylephrine. The results suggest that repeatedly heated corn oil causes elevation in blood pressure, vascular inflammation which impairs vascular reactivity thereby predisposing to hypertension. There is a need to educate people not to consume corn oil in a heated state.

Hassan Y, Aziz NA, Al-Jabi SW, Looi I, Zyoud SH

J Cardiovasc Pharmacol Ther, 2010 Sep;15(3):282-8.
PMID: 20472813 DOI: 10.1177/1074248410368049

BACKGROUND: Hypertension and ischemic heart disease (IHD) are among the most prevalent modifiable risk factors for stroke. Clinical trial evidence suggests that antihypertensive medications are recommended for prevention of recurrent ischemic stroke in hypertensive and normotensive patients.
OBJECTIVES: The objectives of this study were to analyze and evaluate the utilization of antihypertensive medication for acute ischemic stroke (AIS) or transient ischemic attack (TIA) survivors in relation to recent recommendations and guidelines and to compare their use among patients with or without IHD.
METHODS: This was a retrospective cohort study of all patients with AIS/TIA attending the hospital from July 1, 2008 to December 31, 2008. Demographic data, clinical characteristics, different classes of antihypertensive medications, and different antihypertensive combinations prescribed to AIS/TIA survivors were analyzed among patients with and without IHD. Statistical Package for Social Sciences (SPSS) program version 15 was used for data analysis.
RESULTS: In all, 383 AIS/TIA survivors were studied, of which 66 (19.5%) had a documented history of IHD. Three quarters (n = 260; 76.9%) of AIS or TIA survivors received antihypertensive medication, mostly as monotherapy, at discharge. The majority of patients (n = 201, 59.5%) were prescribed angiotensin-converting enzyme inhibitors (ACEIs). Patients with IHD were significantly prescribed more β-blockers than patients without IHD (P = .003). A history of hypertension, a history of diabetes mellitus, and age were significantly associated with prescription of antihypertensive medications at discharge (P < .001, P < .001, and P < .001, respectively).
CONCLUSION: Patterns of antihypertensive therapy were commonly but not adequately consistent with international guidelines. Screening stroke survivors for blood pressure control, initiating appropriate antihypertensive medications, and decreasing the number of untreated patients might help reduce the risk of recurrent strokes and increase survival.

The role of oxidative stress, antioxidants and vascular inflammation in cardiovascular disease (a review)

Siti HN, Kamisah Y, Kamsiah J

Vascul Pharmacol, 2015 Aug;71:40-56.
PMID: 25869516 DOI: 10.1016/j.vph.2015.03.005

The concept of mild chronic vascular inflammation as part of the pathophysiology of cardiovascular disease, most importantly hypertension and atherosclerosis, has been well accepted. Indeed there are links between vascular inflammation, endothelial dysfunction and oxidative stress. However, there are still gaps in our understanding regarding this matter that might be the cause behind disappointing results of antioxidant therapy for cardiovascular risk factors in large-scale long-term randomised controlled trials. Apart from the limitations of our knowledge, limitations in methodology and assessment of the body's endogenous and exogenous oxidant-antioxidant status are a serious handicap. The pleiotropic effects of antioxidant and anti-inflammation that are shown by some well-established antihypertensive agents and statins partly support the idea of using antioxidants in vascular diseases as still relevant. This review aims to provide an overview of the links between oxidative stress, vascular inflammation, endothelial dysfunction and cardiovascular risk factors, importantly focusing on blood pressure regulation and atherosclerosis. In view of the potential benefits of antioxidants, this review will also examine the proposed role of vitamin C, vitamin E and polyphenols in cardiovascular diseases as well as the success or failure of antioxidant therapy for cardiovascular diseases in clinical trials.

PMID: 25436515 DOI: 10.1186/1471-2458-14-S3-S3

Objectives: The objectives are to assess the prevalence and determinants of cardiovascular disease (CVD) risk factors among the residents of Community Housing Projects in metropolitan Kuala Lumpur, Malaysia.
Method: By using simple random sampling, we selected and surveyed 833 households which comprised of 3,722 individuals. Out of the 2,360 adults, 50.5% participated in blood sampling and anthropometric measurement sessions. Uni and bivariate data analysis and multivariate binary logistic regression were applied to identify demographic and socioeconomic determinants of the existence of having at least one CVD risk factor.
Results: As a Result, while obesity (54.8%), hypercholesterolemia (51.5%), and hypertension (39.3%) were the most common CVD risk factors among the low-income respondents, smoking (16.3%), diabetes mellitus (7.8%) and alcohol consumption (1.4%) were the least prevalent. Finally, the results from the multivariate binary logistic model illustrated that compared to the Malays, the Indians were 41% less likely to have at least one of the CVD risk factors (OR = 0.59; 95% CI: 0.37 - 0.93).
Conclusion: In Conclusion, the low-income individuals were at higher risk of developing CVDs. Prospective policies addressing preventive actions and increased awareness focusing on low-income communities are highly recommended and to consider age, gender, ethnic backgrounds, and occupation classes.

Fulltext Prevention and management of new-onset diabetes mellitus in kidney transplantation

Khong MJ, Chong CP

Neth J Med, 2014 Apr;72(3):127-34.
PMID: 24846925

New-onset diabetes mellitus after transplantation (NODAT) is one of the complications that is increasingly occurring among kidney transplanted patients. It is associated with the risk of cardiovascular disease, graft failure and mortality. The risk of NODAT development increases with time from transplantation. Therefore, early detection and prompt action are essential in reducing the risk of NODAT and its complications. This paper aims to review the screening parameters, prevention and management strategies for NODAT in both pre- and post-transplantation conditions. The pre-transplant patient should be screened for diabetes and cardiometabolic risk factors. Blood glucose evaluation for the pre-transplantation period is important for early detection of impaired glucose tolerance (IGT) and impaired fasting glucose (IFG), which are highly associated with the incidence of NODAT. Post-kidney transplant patients should have periodical blood glucose monitoring with more frequent assessment in the initial phase. As early hyperglycaemia development is a strong predictor for NODAT, prompt intervention is needed. When NODAT develops, monitoring and control of blood glucose profile, lipid profile, microalbuminuria, diabetic complications and comorbid conditions is recommended. Immunosuppressive regimen modification may be considered as suggested by the Kidney Disease: Improving Global Outcomes (KDIGO) guideline to reverse or to improve the diabetes after weighing the risk of rejection and other potential adverse effects. Strategies for modifying immunosuppressive agents include dose reduction, discontinuation, and selection of calcineurin inhibitor (CNI), anti-metabolite agents, mammalian target of rapamycin inhibitors (mTORi), belatacept and corticosteroids. Lifestyle modification and a conventional anti-diabetic approach, as in the type 2 diabetes mellitus guidelines, are also recommended in NODAT management.

PMID: 23835719 DOI: 10.1016/S2221-1691(13)60105-7

The divine tree neem (Azadirachta indica) is mainly cultivated in the Indian subcontinent. Neem has been used extensively by humankind to treat various ailments before the availability of written records which recorded the beginning of history. The world health organization estimates that 80% of the population living in the developing countries relies exclusively on traditional medicine for their primary health care. More than half of the world's population still relies entirely on plants for medicines, and plants supply the active ingredients of most traditional medical products. The review shows the neem has been used by humankind to treat various ailments from prehistory to contemporary.

Ahmad N, Hassan Y, Tangiisuran B, Meng OL, Abd Aziz N, Ahmad FU, et al.

J Eval Clin Pract, 2013 Oct;19(5):798-804.
PMID: 22583820 DOI: 10.1111/j.1365-2753.2012.01852.x

RATIONALE, AIMS AND OBJECTIVES: Existing literature suggests that doctors' poor adherence with guidelines is one of the major contributing factors to suboptimal control of hypertension. This study aims to evaluate doctors' adherence with Malaysian clinical practice guideline (CPG 2008) in a tertiary care hospital, and factors associated with guideline adherence and hypertension control.
METHODS: This was a cross-sectional study conducted at Hospital Pulau Pinang, Penang, Malaysia. Prescriptions written by 26 enrolled doctors to 650 established hypertensive outpatients (25 prescriptions per enrolled doctor) were noted on visit 1 along with patients' demographic and clinical data. The noted prescriptions were classified either as compliant or non-compliant to CPG (2008). Five hundred twenty (80%) of the enrolled patients (20 patients per enrolled doctor) were followed for one more visit. Blood pressure (BP) noted on visit 2 was related to the prescription written on visit 1. SPSS 16 (SPSS Inc., Chicago, IL, USA) was used for data analysis.
RESULTS: Three hundred forty-nine (67.1%) patients received guidelines compliant pharmacotherapy. In multivariate analysis, hypertension clinic had significant negative association with guidelines adherence. Two hundred sixty-five patients (51%) were at goal BP on visit 2. In multivariate analysis, angiotensin-converting enzyme inhibitors and guidelines adherence had significant positive, while renal disease, diabetes mellitus and diabetic clinic had significant negative association with hypertension control.
CONCLUSIONS: An overall fair level of adherence with guidelines and better control of hypertension was observed. Guidelines compliant practices resulted in better control of hypertension. The gaps between what guidelines recommend and clinical practice were especially seen in the pharmacotherapy of uncomplicated hypertension and hypertension with diabetes mellitus and renal disease.

PMID: 19713180

Many studies in Asia have demonstrated that Asian populations may require lower cut-off levels for body mass index (BMI) and waist circumference to define obesity and abdominal obesity respectively, compared to western populations. Optimal cut-off levels for body mass index and waist circumference were determined to assess the relationship between the two anthropometric- and cardiovascular indices. Receiver operating characteristics analysis was used to determine the optimal cut-off levels. The study sample included 1833 subjects (mean age of 44+/-14 years) from 93 primary care clinics in Malaysia. Eight hundred and seventy two of the subjects were men and 960 were women. The optimal body mass index cut-off values predicting dyslipidaemia, hypertension, diabetes mellitus, or at least one cardiovascular risk factor varied from 23.5 to 25.5 kg/m2 in men and 24.9 to 27.4 kg/m2 in women. As for waist circumference, the optimal cut-off values varied from 83 to 92 cm in men and from 83 to 88 cm in women. The optimal cut-off values from our study showed that body mass index of 23.5 kg/m2 in men and 24.9 kg/m2 in women and waist circumference of 83 cm in men and women may be more suitable for defining the criteria for overweight or obesity among adults in Malaysia. Waist circumference may be a better indicator for the prediction of obesity-related cardiovascular risk factors in men and women compared to BMI. Further investigation using a bigger sample size in Asia needs to be done to confirm our findings.
