Abstract
BACKGROUND/AIM: Telmisartan can attenuate two hit pathogenesis of non-alcoholic steatohepatitis (NASH). This study aimed to observe the effect of Telmisartan on non-alcoholic fatty liver disease (NAFLD) activity score (NAS) and fibrosis score in NASH patients. PATIENTS AND METHODS A total of 50 NASH patients were randomized; 35 of group 1 were treated with Telmisartan 40/80 mg once daily with life style modification (TL) and 15 of group 2 underwent only life style modification (L) for 1 year. At the end, 20 of TL group and 10 of L group were analyzed. Those who showed NAS improvement ≥ 2 or NAS improvement ≥ 1 with fibrosis improvement ≥ 1 were considered as responders. RESULTS Baseline alanine aminotransferase (ALT), aspartate aminotransferase (AST), insulin resistance index, components of metabolic syndrome, age, and sex were similar in both groups. At the end of study, NAS improvement in TL and L groups was 2.15 ± 1.66 and 1.10 ± 0.57 (P = 0.017) and fibrosis improvement was 0.65 ± 0.93 and -0.30 ± 0.48 (P = 0.001), respectively. NAS improved by ≥ 2 in 13 (65%) and 2 (20%) patients and fibrosis score improved by ≥ 1 in 8 (40%) patients and none of the patients in TL group and L group, respectively. Telmisartan and life style modification could improve steatosis, ballooning, lobular inflammation, and fibrosis. Life style modification could improve ballooning only, but fibrosis deteriorated. TL group showed improvement in NAS and fibrosis score [P value: 0.035; odds ratio (OR) =92.07, confidence interval (CI) =1.39-6106] to the level of response by regression analysis. Weight reduction and improvement of metabolic syndrome did not influence the response. There were similar minor adverse events in both groups. CONCLUSION Telmisartan improved NAS and fibrosis score in NASH with insignificant adverse events.

Abstract
AIMS: The primary questions asked by the MEDINA (MEtabolic parameters, DIabetes mellitus and NephropAthy) study are: 1) Do angiotensin converting enzyme inhibitors (ACE-I) have any advantages over angiotensin receptor blockers (ARB)? 2) Should the other drug for combination be a diuretic or a calcium-channel blocker (CCB)? 3) How are the risks reduced by the co administration of a statin? METHODS A total of 439 hypertensive patients with metabolic syndrome and/or diabetes mellitus were randomized to 2 groups: group 1--ramipril (ACE-I) or perindopril and group 2--losartan (ARB). Hydrochlorothiazide (diuretic) or amlodipine (CCB) were added to both groups. As a third step, a statin was added. RESULTS Blood pressure decreased 24.1/13.3 mmHg in the ACE inhibitor group and 25.9/13.5 in the losartan group. The difference was insignificant. Adding either hydrochlorothiazide or amlodipin was equally effective. There were no significant differences on metabolic parameters in the trial arms. Cholesterol level decreased by 0.95 mmol/L in the ACE-I group and 1.02 mmol/L in the ARB group (ns). CONCLUSION MEDINA has so far confirmed the equivalence of ACE-I and ARB in hypertension treatment. Adding either diuretic or CCB was equally effective. Our data support the current recommendations on adding a statin to reduce cardiovascular risk.

Abstract
The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) is reevaluated considering information from new clinical trials, meta-analyses, and recent subgroup and explanatory analyses from ALLHAT, especially those regarding heart failure (HF) and the association of drug treatment with new-onset diabetes mellitus (DM) and its cardiovascular disease (CVD) consequences. Chlorthalidone was superior to (1) doxazosin mesylate in preventing combined CVD (CCVD) (risk ratio [RR], 1.20; 95% confidence interval [CI], 1.13-1.27), especially HF (RR, 1.80; 95% CI, 1.40-2.22) and stroke (RR, 1.26; 95% CI, 1.10-1.46); (2) lisinopril in preventing CCVD (RR, 1.10; 95% CI, 1.05-1.16), including stroke (in black persons only) and HF (RR, 1.20; 95% CI, 1.09-1.34); and (3) amlodipine besylate in preventing HF, overall (by 28%) and in hospitalized or fatal cases (by 26%). Central independent blinded reassessment of HF hospitalizations confirmed each comparison. Results were consistent by age, sex, race (except for stroke and CCVD), DM status, metabolic syndrome status, and renal function level. Neither amlodipine nor lisinopril was superior to chlorthalidone in preventing end-stage renal disease overall, by DM status, or by renal function level. In the chlorthalidone arm, new-onset DM was not significantly associated with CCVD (RR, 0.96; 95% CI, 0.88-2.42). Evidence from subsequent analyses of ALLHAT and other clinical outcome trials confirm that neither alpha-blockers, angiotensin-converting enzyme inhibitors, nor calcium channel blockers surpass thiazide-type diuretics (at appropriate dosage) as initial therapy for reduction of cardiovascular or renal risk. Thiazides are superior in preventing HF, and new-onset DM associated with thiazides does not increase CVD outcomes.

Abstract
BACKGROUND Antihypertensive drugs with favorable metabolic effects are advocated for first-line therapy in hypertensive patients with metabolic/cardiometabolic syndrome (MetS). We compared outcomes by race in hypertensive individuals with and without MetS treated with a thiazide-type diuretic (chlorthalidone), a calcium channel blocker (amlodipine besylate), an alpha-blocker (doxazosin mesylate), or an angiotensin-converting enzyme inhibitor (lisinopril). METHODS A subgroup analysis of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT), a randomized, double-blind hypertension treatment trial of 42 418 participants. We defined MetS as hypertension plus at least 2 of the following: fasting serum glucose level of at least 100 mg/dL, body mass index (calculated as weight in kilograms divided by height in meters squared) of at least 30, fasting triglyceride levels of at least 150 mg/dL, and high-density lipoprotein cholesterol levels of less than 40 mg/dL in men or less than 50 mg/dL in women. RESULTS Significantly higher rates of heart failure were consistent across all treatment comparisons in those with MetS. Relative risks (RRs) were 1.50 (95% confidence interval, 1.18-1.90), 1.49 (1.17-1.90), and 1.88 (1.42-2.47) in black participants and 1.25 (1.06-1.47), 1.20 (1.01-1.41), and 1.82 (1.51-2.19) in nonblack participants for amlodipine, lisinopril, and doxazosin comparisons with chlorthalidone, respectively. Higher rates for combined cardiovascular disease were observed with lisinopril-chlorthalidone (RRs, 1.24 [1.09-1.40] and 1.10 [1.02-1.19], respectively) and doxazosin-chlorthalidone comparisons (RRs, 1.37 [1.19-1.58] and 1.18 [1.08-1.30], respectively) in black and nonblack participants with MetS. Higher rates of stroke were seen in black participants only (RR, 1.37 [1.07-1.76] for the lisinopril-chlorthalidone comparison, and RR, 1.49 [1.09-2.03] for the doxazosin-chlorthalidone comparison). Black patients with MetS also had higher rates of end-stage renal disease (RR, 1.70 [1.13-2.55]) with lisinopril compared with chlorthalidone. CONCLUSIONS The ALLHAT findings fail to support the preference for calcium channel blockers, alpha-blockers, or angiotensin-converting enzyme inhibitors compared with thiazide-type diuretics in patients with the MetS, despite their more favorable metabolic profiles. This was particularly true for black participants.

Abstract
The objective of the present study was to explore the effect of carvedilol treatment on metabolic parameters in patients with metabolic syndrome. A total of 77 patients > or = 20 years of age (59 females, 18 males, mean age, 52.3 +/- 10.3) with stage 1 hypertension who fulfilled at least 3 of the metabolic syndrome criteria proposed by NCEP-ATP III were included in this prospective, randomized, controlled study. Patients were randomly assigned to receive daily treatment with carvedilol (n = 27, 12.5 mg/day orally for the first 2 days and 25 mg/day thereafter), atenolol (n = 26, 50 mg/day orally), or doxazosin (n = 24, 2 mg/day orally) for 90 days. Doses were doubled at the end of the 3rd week in patients whose blood pressure was inadequately controlled and amlodipine 10 mg was added to the treatment if the target blood pressure was still not reached at the end of week 6. The biochemical parameters and insulin sensitivity based on the HOMA-IR model were evaluated at baseline and at the end of treatment. Similar reductions in systolic and diastolic blood pressure were observed in all groups (P > 0.05). A significant decrease in HDL cholesterol levels occurred in the doxazosin and atenolol groups compared to the carvedilol group (percent change: -5.6 +/- 13.5 and -8 +/- 9.8 versus -0.1 +/- 12.2, respectively; P < 0.05) and a significant increase in apolipoprotein A1 level was observed in the carvedilol group compared to the doxazosin and atenolol groups (percent change: + 4.3 +/- 9.6 versus - 0.5 +/- 10.6 and -2.3 +/- 6.6, respectively; P < 0.05). There were no significant differences among the groups with respect to other parameters. It is concluded antihypertensive treatment with carvedilol in patients with metabolic syndrome effectively reduces blood pressure without adversely affecting metabolic parameters.
