    Raised leptin levels have been reported in the placentae and serum of women with elevated blood pressure and proteinuria during pregnancy. The role of leptin in this however remains unknown. This study investigates the effect of leptin administration on systolic blood pressure (SBP) and proteinuria and serum markers of endothelial activation during pregnancy in Sprague Dawley rats. From day 1 of pregnancy, 24 rats were randomised into those given either saline (group 1) or leptin at 60 or 120 μ g/kg/body weight/day (groups 2 and 3 resp.). SBP was measured every 5 days and 24-h urinary protein was measured at days 0 and 20 of pregnancy. Animals were euthanised on day 20 of pregnancy, and serum was collected for estimation of E-selectin and ICAM-1. Compared to group 1, SBP during the latter part of the pregnancy was significantly higher in the leptin-treated group (P < 0.01). Urinary protein excretion, serum E-selectin, and ICAM-1 were significantly higher in leptin-treated rats (P < 0.05). It seems that leptin administration to normotensive Sprague Dawley rats during pregnancy significantly increases SBP, urinary protein excretion, and markers of endothelial activation. However, further studies are required to examine the underlying mechanism responsible for this and its relevance to preeclampsia in humans.

    The aim of current study was to assess the effectiveness of losartan 50 mg in reducing blood pressure among post-dialysis euvolemic hypertensive patients, observing their survival trends and adverse events during the course of study. A multicentre, prospective, randomised, single-blind trial was conducted to assess the effect of losartan 50 mg every other day (EOD), once a morning (OM) among post-dialysis euvolemic hypertensive patients. Post-dialysis euvolemic assessment was done by a body composition monitor (BCM). Covariate Adaptive Randomization was used for allocation of participants to the standard or intervention arm. Of the total 229 patients, 96 (41.9%) were identified as post-dialysis euvolemic hypertensive. Final samples of 88 (40.1%) patients were randomized into standard and intervention arms. After follow-up of 12 months' pre-dialysis systolic (p

    INTRODUCTION: Calcium channel blockers are well established modalities for the treatment of hypertension. However, in spite of the availability of many efficacious agents, hypertension control continues to be poor. One reason is poor tolerability due to adverse events. Racial differences also exist. Lercanidipine, a third-generation calcium channel blocker, is associated with better tolerability. However, it has not been studied in the Asian population. This study examines its efficacy and tolerability in Asian subjects of different ethnicities.
    METHODS: This was an eight-week open label study of adults with mild to moderate hypertension. Blood pressure (BP), pulse rate, self-administered symptom check and laboratory evaluations were done at baseline. Patients were prescribed 10 mg lercanidipine, with up-titration to 20 mg if BP was not controlled at Week 4. Baseline evaluations were repeated at Week 8. Adverse events were also enumerated.
    RESULTS: 27 patients (mean age 53.4 +/- 12.1 years) completed the study. The baseline systolic BP (SBP), diastolic BP (DBP) and heart rate was 159 +/- 12.2, 96.6 +/- 7.7 mmHg and 71 +/- 13/min, respectively. Three racial groups were represented. SBP and DBP decreased significantly after four weeks of therapy. A further reduction to 139 +/- 14.3 and 88 +/- 9.8 (p-value is less than 0.0001) was seen in Week 8. The absolute SBP and DBP reduction was 20.5 mmHg (95 percent confidence interval [CI] 16.5-24.5, p-value is less than 0.0001) and 9.3 mmHg (95 percent CI 6.2-12.5, p-value is less than 0.0001), respectively. All adverse symptoms, except for palpitations, were reduced at the end of the study.
    CONCLUSION: Lercanidipine is efficacious and well tolerated in Asians of different ethnicities. Its BP lowering effects and tolerability in Asians appear to be similar to other studies on Caucasians and other calcium channel blockers.

    Oleic acid has been shown to lower high blood pressure and provide cardiovascular protection. Curiosity arises as to whether super olein (SO), red palm olein (RPO) and palm olein (PO), which have high oleic acid content, are able to prevent the development of hypertension.
