BACKGROUNDAntihypertensive drugs have been linked to new-onset osteoporotic fracture (NOF), and different classes of antihypertensive drugs may alter the risk for the development of NOF; however, the classic effect of different antihypertensive drugs on the development of NOF in the elderly has not been well studied during long-term follow-up.

METHODSIn this study, we investigated the association between different classic antihypertensives and the development of NOF in the elderly. This was a longitudinal cohort study performed using data from claim forms submitted to the Taiwan Bureau of National Health Insurance in Central Taiwan, China including case patients with NOF aged 65-80 years from January 2002 to December 2012 and non-NOF controls. Prescriptions for antihypertensives before the index date were retrieved from a prescription database. We estimated the hazard ratios (HR s) of NOF associated with antihypertensive use. Non-NOF controls served as the reference group.

RESULTSA total of 128 patients with NOF were identified from among 1144 patients with hypertension during the study period. The risk of NOF after adjusting age, sex, comorbidities, and concurrent medications was higher among the users of angiotensin-converting enzyme (ACE) inhibitors (HR, 1.64; 95% confidence interval [CI], 1.01-2.66) than among nonusers. Patients who took calcium channel blockers (CCBs) (HR, 0.70; 95% CI, 0.49-0.99) were at a lower risk of developing NOF than nonusers. Loop diuretics, thiazide diuretics, angiotensin receptor blocker, beta-blocker, and alpha-blocker were not associated with the risk of NOF.

CONCLUSIONSElderly with hypertension who take CCBs are at a lower risk of NOF and that the use of ACE inhibitors was associated with a significantly increased risk of developing NOF during the 11-year follow-up.

PURPOSE: To compare the efficacy and safety of latanoprost, bimatoprost, travoprost and timolol in reducing intraocular pressure (IOP) in patients with primary open angle glaucoma. METHODS: This was a prospective study conducted at a tertiary-care centre. One hundred and forty patients with newly diagnosed primary open angle glaucoma were randomly assigned to treatment with latanoprost (0.005%), bimatoprost (0.03%), travoprost (0.004%) or timolol gel (0.5%); 35 patients were assigned to each group. All patients were followed for 2, 6, and 12 weeks. The main outcome measure studied was the change in IOP at week 12 from the baseline values. Safety measures included recording of adverse events. RESULTS: The mean IOP reduction from baseline at week 12 was significantly more with bimatoprost (8.8 mmHg, 35.9%) than with latanoprost (7.3 mmHg, 29.9%), travoprost (7.6 mmHg, 30.8%) or timolol (6.7 mmHg, 26.6%) (ANOVA and Student's t-tests, p < 0.001). Among the prostaglandins studied, bimatoprost produced a maximum reduction in IOP (-2.71; 95% confidence interval [CI], -2.25 to -3.18) followed by travoprost (-1.27; 95% CI, -0.81 to -1.27) and latanoprost (-1.25; 95% CI, -0.79 to -1.71); these values were significant when compared to timolol at week 12 (Bonferroni test, p < 0.001). Latanoprost and travoprost were comparable in their ability to reduce IOP at each patient visit. Ocular adverse-events were found in almost equal proportion in patients treated with bimatoprost (41.3%) and travoprost (41.9%), with a higher incidence of conjunctival hyperemia (24.1%) seen in the bimatoprost group. Timolol produced a significant drop in heart rate (p < 0.001) at week 12 when compared to the baseline measurements. CONCLUSIONS: Bimatoprost showed greater efficacy when compared to the other prostaglandins, and timolol was the most efficacious at lowering the IOP. Conjunctional hyperemia was mainly seen with bimatoprost. However, the drug was tolerated well and found to be safe.

Nonalcoholic steatohepatitis (NASH) is characterized by hepatocyte injury and inflammatory cell infiltration, which has been linked to peripheral insulin resistance and increased levels of triglycerides in the liver. The purposes of this study were to establish a mouse model of NASH by feeding mice a 60% high-fat diet (HFD) and to demonstrate the anti-fibrotic effects of oleuropein, which has been shown to have anti-oxidant and anti-inflammatory properties, in this HFD-induced mouse model of NASH. C57BL/6 mice were divided into three groups: a regular diet group (Chow), a HFD group and an oleuropein-supplemented HFD group (OSD), which was fed a 0.05% OSD for 6 months. The effects of oleuropein in this model were evaluated using biochemical, histological and molecular markers. The expression levels of alpha-smooth muscle actin (alpha-SMA)and collagen type I in the HFD and OSD groups were evaluated using real-time PCR and western blotting. The body weight, biochemical marker levels, nonalcoholic fatty liver disease activity score, homeostasis model of assessment-insulin resistance (HOMA-IR) and leptin levels observed in the HFD group at 9 and 12 months were higher than those observed in the Chow group. The HOMA-IR and leptin levels in the OSD group were decreased compared with the HFD group. In addition, alpha-SMA and collagen type I expression were decreased by oleuropein treatment. We established a NASH model induced by HFD and demonstrated that this model exhibits the histopathological features of NASH progressing to fibrosis. Our results suggest that oleuropein may be pharmacologically useful in preventing the progression of steatohepatitis and fibrosis and may be a promising agent for the treatment of NASH in humans.

Some patients with chronic obstructive pulmonary disease (COPD) have pulmonary hypertension (PH) that adversely affects survival. We performed a systematic review and meta-analysis to assess whether PH-specific therapies have an effect for stable COPD. Data sources were Medline, EMBASE, Cochrane Central Register of Controlled Trials, Korea med and references from relevant publications. Randomized prospective trials that compared PH specific therapy in COPD for more than 6 weeks with placebo were included. The outcomes were the exercise capacity and adverse events. Four randomized controlled trials involving 109 subjects were included in the analysis. Two trials involved bosentan, one sildenafil and one beraprost. The studies varied in duration of treatment from 3 to 18 months. In a pooled analysis of four trials, exercise-capacity was not significantly improved with PH-specific treatment for COPD (risk ratio, -5.1; 95% CI, -13.0 to 2.8). COPD with overt PH significantly improved the exercise capacity (mean difference, 111.6; 95% CI, 63.3 to 159.9) but COPD with PH unknown did not (mean difference, 26.6; 95% CI, -24.3 to 77.5). There was no significant difference in hypoxemia (mean difference, 2.6; 95% CI, -3.7 to 8.8). PH specific treatments have a significant effect in improving exercise capacity in COPD with overt PH.

BACKGROUND/AIMS: We assessed the efficacy and safety of bosentan in patients with pulmonary arterial hypertension (PAH). METHODS: We surveyed randomized controlled trials (RCTs) of the efficacy and safety of bosentan in patients with PAH using MEDLINE, EMBASE, the Cochrane Controlled Trials Register, and manual searches. Meta-analysis of RCTs was performed to determine treatment efficacy and safety outcomes. Results are presented as odds ratios (ORs) or weighted mean differences (WMDs). RESULTS: Meta-analysis of seven RCTs including a total of 410 patients and 296 controls revealed that the 6-minute work distance was significantly higher in the bosentan group than in the placebo group (WMD, 46.19; 95% confidence interval [CI], 21.20 to 71.19; p = 2.9 x 10(-5)). Compared with the placebo, bosentan significantly reduced the mean pulmonary arterial pressure in patients with PAH (WMD, -6.026; 95% CI, -8.785 to -3.268, p = 1.8 x 10(-6)). The bosentan therapy group worsened less clinically than the placebo group (OR, 0.252; 95% CI, 0.140 to 0.454; p = 4.6 x 10(-7)). The incidence of serious adverse events did not differ between the bosentan and placebo groups (OR, 0.948; 95% CI, 0.556 to 1.614; p = 0.843). However, the results of the abnormal liver function test (LFT) were significantly higher in the bosentan group than in the placebo group (OR, 2.312; 95% CI, 1.020 to 5.241; p = 0.045). CONCLUSIONS: This meta-analysis shows that bosentan can treat PAH effectively. However, bosentan increased the incidence of abnormal LFT results compared with the placebo.

OBJECTIVETo investigate the effects and safety of Western medicine combined with Chinese medicine (CM) based on syndrome differentiation in the treatment of elderly polarized hypertension (PHPT), or isolated systolic hypertension with low diastolic blood pressure (DBP).

METHODSA total of 125 elderly patients with PHPT were randomly assigned to two groups: 59 in the control group treated by Western medicine and 66 in the intervention group treated by Western medicine combined with CM treatment. Based on syndrome differentiation, the patients in the intervention group were further divided into subgroups of yang-qi deficiency and yin-qi deficiency. All subjects were treated with Western medicine of Amlodipine Besylate Tablets and Irbesartan Tablets (or Irbesartan and Hydrochlorothiazide Tablets), to decrease their systolic blood pressure (SBP) slowly to 125-135 mm Hg in 2-6 weeks. In the intervention group, Shiyiwei Shenqi Capsule was given additionally to the subgroup of yang-qi deficiency at the dosage of 3-5 capsules, thrice a day, while Dengzhan Shengmai Capsule was given additionally to the subgroup of yin-qi deficiency at the dosage of 2 capsules, 2-3 times per day. For all subjects, SBP, pulse pressure (PP), and DBP were measured before treatment and at the terminal of a 6-week treatment. For subjects in the intervention group, left ventricular ejection fraction (LVEF) was also recorded.

RESULTSAfter a 6-week treatment, the SBP in the two groups and the PP in the intervention group decreased significantly compared to those before treatment (P<0.05), while the PP in the control group showed no significant difference between prior and post-treatment (P>0.05). After treatment, the DBP in the control group decreased (P>0.05), while the DBP and LVEF in the intervention group showed an increase tendency although it had no statistical significance (P>0.05). When subjects in the intervention group were classified further by the course of disease, the DBP and LVEF of subjects whose course of disease were less than 2 years, increased significantly after treatment (P<0.05).

CONCLUSIONWestern medicine combined with CM treatment based on syndrome differentiation was safer and more effective than Western medicine alone in the treatment of elderly PHPT, because it not only reduced SBP but also improved DBP, which might lower the incidence of the cardiovascular and cerebrovascular events.

The authors performed a multicenter prospective study to evaluate the feasibility and safety of intravenous nicardipine hydrochloride for acute hypertension in patients with intracerebral hemorrhage (ICH). This study included 88 patients (mean age: 58.3 yr, range 26-87 yr) with ICH and acute hypertension in 5 medical centers between August 2008 and November 2010, who were treated using intravenous nicardipine. Administration of nicardipine resulted in a decrease from mean systolic blood pressure (BP) (175.4 +/- 33.7 mmHg) and diastolic BP (100.8 +/- 22 mmHg) at admission to mean systolic BP (127.4 +/- 16.7 mmHg) and diastolic BP (67.2 +/- 12.9 mmHg) in 6 hr after infusion (P < 0.001, mixed-effect linear models). Among patients who underwent follow-up by computed tomography, hematoma expansion at 24 hr (more than 33% increase in hematoma size at 24 hr) was observed in 3 (3.4%) of 88 patients. Neurological deterioration (defined as a decrease in initial Glasgow coma scale > or = 2) was observed in 2 (2.2%) of 88 patients during the treatment. Aggressive nicardipine treatment of acute hypertension in patients with ICH can be safe and effective with a low rate of neurological deterioration and hematoma expansion.

This paper presents a case of reversible dysphasia occurring in a patient prescribed atorvastatin in combination with indapamide. A milder dysphasia recurred with the prescription of rosuvastatin and was documented on clinical examination. This resolved following cessation of rosuvastatin. The case highlights both a need for a wider understanding of potential drug interactions through the CYP 450 system and for an increased awareness, questioning and reporting of drug side-effects.

BACKGROUNDPercutaneous transluminal renal angioplasty with stent is an effective procedure for atherosclerotic renal artery stenosis. However, the decision to perform this procedure has recently raised considerable debate. The aim of this study was to assess the effects of percutaneous transluminal renal angioplasty with stent in atherosclerotic renal artery stenosis patients, especially as it relates to blood pressure control and renal function improvement.

METHODSA retrospective analysis was made of the clinical data from 125 atherosclerotic renal artery stenosis patients who underwent percutaneous transluminal renal angioplasty from July 2004 to June 2008 in the Department of Vascular Surgery of Beijing Chaoyang Hospital. We compared blood pressure, number of oral antihypertensive medications, and renal function changes pre and post-procedure at 24 months follow-up.

RESULTSA total of 125 atherosclerotic renal artery stenosis patients underwent percutaneous transluminal renal angioplasty and 143 stents were placed. At 24 months follow-up, both systolic and diastolic blood pressure and the number of oral antihypertensive medications were significantly reduced (P < 0.05). Overall, the estimated glomerular filtration rate did not change significantly (P > 0.05); however, a significant increase in estimated glomerular filtration rate was observed in the subgroup of patients with a lower baseline estimated glomerular filtration rate and in the subgroup of patients with bilateral renal artery stenosis (P < 0.05).

CONCLUSIONPercutaneous transluminal renal angioplasty is a safe procedure for atherosclerotic renal artery stenosis patients, providing a significant improvement in blood pressure control and reduction in the number of oral antihypertensive medications.
