OBJECTIVETo investigate the efficacy and safety of bisoprolol/hydrochlorothiazide (Lodoz) in patients with mild and moderate essential hypertension.
METHODSAfter 2 weeks of placebo run-in period, 90 hypertensive patients with sitting diastolic blood pressure (DBP) between 95 and 109 mm Hg (1 mm Hg = 0.133 kPa) and systolic blood pressure (SBP) below 180 mm Hg were treated by Lodoz (2.5 mg/6.25 mg/day) for 4 weeks. If DBP > 90 mm Hg at 4 weeks, Lodoz (5 mg/6.25 mg/day) was given for another 8 weeks. Clinic systolic and diastolic blood pressure measurements and ambulatory blood pressure monitoring (ABPM) were performed at the end of placebo run-in period and at 4 and 8 weeks.
RESULTSAfter 4 or 8 weeks treatment with Lodoz, clinic systolic and diastolic blood pressure, the 24-hour mean, daytime and nocturnal blood pressures reduced significantly compared to placebo run-in period [SBP and DBP reduced (14.89 +/- 10.99)/(10.37 +/- 7.35) mm Hg (4 weeks) and (19.40 +/- 10.55)/(13.31 +/- 7.77) mm Hg (8 weeks)] respectively (P < 0.05). The total efficacy rate is 59.3% for Lodoz 2.5 mg/6.25 mg and 69.8% for Lodoz 5 mg/6.25 mg. The trough: peak ratio for SBP and DBP were 91.5% and 94.4% with Lodoz 2.5 mg/6.25 mg, and 79.9% and 80.5% with Lodoz 5 mg/6.25 mg. The smoothness index (SI) for SBP and DBP were 9.07 and 6.48 with Lodoz 2.5 mg/6.25 mg, and 4.17 and 4.47 with Lodoz 5 mg/6.25 mg, respectively. Few side effects were observed during treatment including mild headache and dizziness and slightly increased serum urea acid.
CONCLUSIONLodoz (2.5 mg/6.25 mg and 5 mg/6.25 mg) can effectively reduce the 24 hours blood pressure in patients with mild to moderate essential hypertension.

OBJECTIVE:
To detect potential variant in a male neonate affected with congenital nephrogenic diabetes insipidus (CNDI).
METHODS:
Clinical data of the patient was collected. Genomic DNA was extracted from peripheral blood samples from the child and his parents. The whole coding regions of the arginine vasopressin V2 receptor (AVPR2) gene were amplified by PCR and subjected to Sanger sequencing.
RESULTS:
The patient presented recurrent fever and polyuria after birth. Multiple blood gas analyses indicated hypernatremia. Ultrasound showed bilateral hydronephrosis and hydroureter. The patient was partially responsive to hydrochlorothiazide. DNA analysis identified a hemizygous frameshift variant c.890-899delACCCGGAGGC in exon 2 of the AVPR2 gene in the proband. His mother was heterozygous for the same variant.
CONCLUSION
The c.890-899delACCCGGAGGC variant of the AVPR2 gene probably underlies the CNDI in the child. Above discovery has enriched to spectrum of CNDI associated variants.

OBJECTIVETo explore the association between polymorphism in the ACE I/D gene and blood pressure-lowering response to hydrochlorothiazide (HCTZ) in 829 patients.
METHODSHCTZ 12.5 mg was taken once a day for six weeks. The blood pressure reduction and ratio reaching target blood pressure were compared in different ACE genotype groups.
RESULTSThe reduction in SBP of patients carrying DD was greater than that in other groups carrying II or ID (12.2 mmHg versus 5.4 mmHg, 12.2 mmHg versus 4.4 mmHg, respectively, P<0.05). The reduction in MAP of patients carrying DD was also greater than that in other groups carrying II or ID (6.9 mmHg versus 3.9 mmHg, 6.9 mmHg versus 3.6 mmHg, respectively, P<0.05). The ratio reaching target blood pressure in DD groups was significantly higher than that in II or ID groups (P<0.05). The pre-treatment SBP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of SBP. The pre-treatment DBP, aldosterone levels, DD genotype entered the multi-linear regression model significantly and might affect the reduction of DBP. The pre-treatment MAP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of MAP.
CONCLUSIONACE genotyping is associated with blood pressure-lowering response to HCTZ. Specific genotypes might be associated with the response to specific antihypertensive treatment.

OBJECTIVESTo analyse the control rate of irbesartan/hydrochlorothiazide (HCTZ) combination tablets (COAPROVEL) in the treatment of patients with mild to moderate primary hypertension.
METHODSIn this multi-center, open, single therapy trial, the enrolled patients aged 18-75 were treated with irbesartan/HCTZ combination tablets for 8 weeks. The initial dose comprised one tablet of irbesartan (150 mg)/HCTZ (12.5 mg) once a day during the first 2 weeks. If diastolic blood pressure was greater than 85 mm Hg at the end of the second or fourth weeks, irbesartan (300 mg)/HCTZ (12.5 mg) once a day or irbesartan (300 mg)/HCTZ (25 mg) once a day were added respectively.
RESULTSIn 968 patients with mild to moderate hypertension enrolled, 920 patients were followed up for 8 weeks. (1) After 1 week of treatment, irbesartan/HCTZ combination tablets lowered systolic blood pressure by 11.87 mm Hg and diastolic blood pressure by 8.54 mm Hg (P < 0.01). After 8 weeks of treatment, the corresponding decreases were 21.97 mm Hg and 16.08 mm Hg, respectively (P < 0.01). (2) After 2, 4 and 8 weeks of treatment, 526, 703 and 769 patients reached blood pressure target (diastolic blood pressure less than 85 mm Hg). The control rates were 57.17%, 76.41% and 83.59%, respectively. (3) Among the 920 patients who completed the trial, 637 patients took irbesartan (150 mg)/HCTZ (12.5mg) once a day (69.24%), 211 patients took irbesartan (300 mg)/HCTZ (12.5 mg) once a day (22.93%), and 72 patients took irbesartan (300 mg)/HCTZ (25 mg) once a day (7.82%). (4) In the intention-to-treat analysis, no adverse reaction was observed in 903 patients (93.29% of the patients enrolled).
CONCLUSIONSWhen irbesartan/HCTZ combination regimen are used in the treatment of patients with mild to moderate primary hypertension, the proportion of patients reaching blood pressure target is high and adverse reactions are rare.

OBJECTIVETo assess the efficacy and safety of valsartan/hydrochlorothiazide (HCTZ) 80/12.5 mg once daily (o.d.) in Chinese patients with mild to moderate essential hypertension who was not adequately controlled by valsartan 80 mg o.d. monotherapy.
METHODSIn this multi-center, double-blind, randomized, active controlled, parallel group trial, 1051 out of 1175 Chinese patients with mild to moderate essential hypertension [DBP >or= 95 mm Hg and < 110 mm Hg (1 mm Hg = 0.133 kPa)] completed single-blind run-in period (valsartan 80 mg o.d. therapy for 4 weeks) after 2 week's wash-out period. At the end of the single-blind run-in period, those patients with DBP >or= 95 mm Hg (n = 864) were randomized in 1:1 ratio to Valsartan and Valsartan 80 mg (n = 429)/HCTZ80/12.5 mg (n = 435) treatment o.d. for 8 weeks. Safety and efficacy was assessed every 4 weeks during double blind phase.
RESULTSAt the end of study, valsartan/HCTZ 80/12.5 mg combination treatment further reduced systolic (-3.5 mm Hg) and diastolic (-2.2 mm Hg) pressures and increased the rate of patients reaching goal BP level (53.9% vs. 40.9%) compared to valsartan 80 mg o.d. monotherapy. Incidence of side effects was similar between the combination therapy and monotherapy groups (8.9% vs. 5.1%, P > 0.05).
CONCLUSIONEfficacy of Valsartan 80 mg/HCTZ 12.5 mg compound was superior to valsartan 80 mg on BP reduction and goal BP control rate in Chinese patients with mild to moderate essential hypertension. The combination of Valsartan 80 mg/hydrochlorothiazide (HCTZ) 12.5 mg provides a suitable treatment for Chinese patients who are not adequately controlled by valsartan 80 mg o.d. monotherapy.

BACKGROUNDHypertension is an important issue in Asia, responsible for up to 66% of cardiovascular disease cases. This randomized controlled trial subgroup analysis compared telmisartan 80 mg (T80)/hydrochlorothiazide 25 mg (H25) singlepill combination with T80 monotherapy, specifically in Chinese and Korean patients.
METHODSPatients with grade 2/3 hypertension were randomized to receive telmisartan 40 mg (T40)/hydrochlorothiazide 12.5 mg (H12.5) combination or T40 monotherapy for one week, before uptitrating the dose to T80/H25 or T80, respectively, for the remaining 6 weeks. The primary endpoint was systolic blood pressure (SBP) mean change from baseline. Secondary endpoints included mean diastolic blood pressure (DBP) change from baseline, and blood pressure (BP) goal achievement. Adverse events were recorded.
RESULTSOf a total 888 patients who were treated, efficacy analyses for Chinese and Korean patients included 127 patients treated with T80/H25 and 54 patients treated with T80. At week 7, mean SBP reductions from baseline were -37.5 mmHg (1 mmHg = 0.133 kPa) and -26.9 mmHg in the T80/H25 and T80 groups (adjusted mean difference, -10.6 mmHg; 95% confidence interval (CI), -15.6 to -5.7). Mean DBP reductions were -19.0 and -14.1 mmHg in the T80/H25 and T80 groups (adjusted mean difference, -4.9 mmHg; 95% CI, -8.0 to -1.8). In total, 56.7% of patients receiving T80/H25 achieved BP goal (<140/90 mmHg) compared with 35.2% receiving T80. SBP goal attainment (<140 mmHg) and DBP goal attainment (<90 mmHg) were also higher in the T80/H25 group compared with the T80 group (SBP: 69.3% vs. 48.1%; DBP: 62.2% vs. 46.3%). A small number of treatment-related adverse events were observed in both T80/H25 (nine patients, 6.9%) and T80 monotherapy (two patients, 3.6%) groups.
CONCLUSIONSIn Chinese and Korean patients with moderate-to-severe hypertension, treatment with T80/H25 provided large reductions in mean SBP and DBP, and high BP goal attainment rates. This once-daily combination is effective and well tolerated in this patient group.

OBJECTIVETo determine whether the blood pressure (BP) response to hydrochlorothiazide (HCTZ) was associated with the angiotensin converting-enzyme (ACE) I/D and aldosterone synthase (CYP11B2)-344T/C polymorphisms.
METHODSThe BP response to HCTZ 12.5 mg once daily for 6 weeks was assessed in 829 subjects with mild or moderate essential hypertension, and compared across the ACE and CYP11B2 genotypes.
RESULTSOf the 829 enrolled subjects, 785 completed the study. The systolic BP response differed according to the ACE (DD 9.4 +/- 15.7 mm Hg, ID 4.8 +/- 16.3 mm Hg, and II 5.1 +/- 14.8 mm Hg, P < 0.01), but not the CYP11B2 genotype (P > 0.05). Subjects with the combination of ACE DD and CYP11B2 CC genotypes tended to have a more pronounced systolic BP reduction than the other genotypic combinations of these 2 genes. Multiple linear regression analyses showed that the ACE DD genotype and serum aldosterone concentration at baseline were associated with the systolic BP reduction after treatment. None of the genetic associations with changes in diastolic BP or mean arterial pressure reached statistical significance (P > 0.05).
CONCLUSIONSThe present study suggested that the ACE DD genotype was associated with the systolic BP response to HCTZ, and that the subjects with the combination of ACE DD and CYP11B2 CC genotypes might have a better BP response to HCTZ than the other genotypic combinations of these 2 genes.

OBJECTIVETo explore the association between G614T single nuclear polymorphism (SNP) of the alpha-adducin gene and the antihypertensive effect of hydrochlorothiazide (HCTZ) in essential hypertensive (EH) patients.
METHODSEight hundred twenty nine EH patients were given 12.5 mg HCTZ/d for six weeks. Alpha-adducin gene G614T SNP in the tenth exon was determined by PCR-RFLP in 754 patients with complete records. All the patients were grouped according to TT, GT and GG genotypes.
RESULTSAfter 6 weeks of HCTZ treatment, the decreases in DBP and MAP of patients carrying 614T allele of alpha-adducin were significantly greater than that of those carrying GG homozygotes (P < 0.05). The decreases in SBP and MAP were significantly greater in patients with the TT genotype as compared with GT or GG genotype (P < 0.05). The effective rate of BP fall by HCTZ was higher in patients with TT genotype than those with GT or GG genotype (P < 0.05). Multivariate stepwise regression analysis showed that the TT genotype and the baseline SBP were the two major predictors affecting the decrease in SBP.
CONCLUSIONThe present study suggests that the alpha-adducin G614T polymorphism is associated with the antihypertensive effect of HCTZ, which is more effective in patients with TT genotype.

OBJECTIVETo investigate the clinical effect of manshuailing oral liquid on patients with congestive heart failure of type heart and kidney Yang deficiency.
METHOD90 patients of heart failure were randomly divided into 2 groups. 45 cases in the routine treatment group (RT) received general therapy including diuretics and digitalis, and 45 cases in the Chinese herb medicine group (CH) were treated basically with the above medicine, with additional manshuailing oral liquid. The clinical effect was summarized 6 weeks after treatment.
RESULTTotal effect rate was 82.2% and 62.2% in CH and RTgroup respectively. Compared with pretreatment, heart function including stroke volume (SV), stroke volume index (SVI), cardiac index (CI), shorten rate of left ventricular short axe (deltaD%), distance of inter-ventricular septal to mitral valve (EPSS) were all improved significantly in both groups (P < 0.05 or P < 0.01), and with even better effects in the CH group than the RT group (P < 0.05 or P < 0.01), except the SV.
CONCLUSIONManshuailing oral liquid can alleviate clinical symptom, decreased EPSS, increase deltaD% and improve heart function.
