Glycemic and blood pressure control in older patients with hypertension and diabetes： association with carotid atherosclerosis

Backgroud Numerous studies have confirmed the effectiveness of slowing the progression of atherosclerosis by blood pressure （Bp） control in patients with hypertension and several studies also showed the efficacy of intensive glycemic control in decreasing progression of carotid intima-media thickness （CIMT） in patients with type 1 and type 2 diabetes. However, few studies have compared the relative importance of glycemic w＇. Bp control in patients with diabetes and hypertension. We aimed to investigate the association between Bp and glycemic control and subclinical carotid atherosclerosis in older patients with hypertension and type 2 diabetes. Methods In a cross-sectional study, B-mode high-resolution ultrasonography of the carotid artery was performed in 670 subjects （508 males and 162 females） aged 60 years or over who had self-reported hypertension and diabetes but no history of coronary heart disease or stroke. Subjects were categorized by their systolic blood pressure： tight control, 〈 130 mmHg; usual control, 130-139 mmHg; or uncontrolled, 〉 140 mmHg, and by their hemoglobin Alc （HbAlc） level： tight control, 〈 6.5%; usual control, 6.5%-7.5%; or uncontrolled, 〉 7.5%, respectively. Results The mean CIMT was 8.20 ±0.11 mm, and carotid plaque was found in 52.5% （352/670） subjects. Overall, 62.1% of the subjects had subclinical carotid atherosclerosis, defined as having either carotid plaque or elevated CIMT （≥ 1.1 ram）. The mean CIMT was significantly different between Bp control categories （7.60 ± 0.09 mm, 7.90 ±0.08 mm, and 8.60 ± 0.12 mm, respectively, P = 0.03） but not between glycemic control categories （8.20± 0.10 mm, 8.1 ±0.08 mm, and 8.40 ± 0.14 ram, respectively, P = 0.13） using ANCOVA analysis. Multivariable logistic regression adjusting for potential confounding factors showed that usual or uncontrolled Bp control were associated with having carotid plaque （OR = 1.08 and OR=1.42, respectively）, or elevated CIMT [Odd ratio （OR） = 1.17, 95% confidence interval （CI） 1.04-2.24, and OR = 1.54, 95% CI 1.36-2.96, respectively compared to tight Bp control; but did not show glycemic control as independent predictor of either having carotid plaque or elevated CIMT. Conclusions In older patients with hypertension and diabetes, blood pressure control, but not glycemic control is associated with subclinical carotid atherosclerosis.

Establishing a predictive model for aspirin resistance in elderly Chinese patients with chronic cardiovascular disease

Background Resistance to anti-platelet therapy is detrimental to patients. Our aim was to establish a predictive model for aspirin resistance to identify high-risk patients and to propose appropriate intervention. Methods Elderly patients （n = 1130） with stable chronic coronary heart disease who were taking aspirin （75 mg） for 〉 2 months were included. Details of their basic characteristics, laboratory test results, and medications were collected. Logistic regression analysis was performed to establish a predictive model for aspirin resistance. Risk score was finally established according to coefficient B and type of variables in logistic regression. The Hosmer-Lemeshow （HL） test and receiver operating characteristic curves were performed to respectively test the calibration and discrimination of the model. Results Seven risk factors were included in our risk score. They were serum creatinine （〉 110 μmol/L, score of 1）; fasting blood glucose （〉 7.0 mmol/L, score of 1）; hyperlipidemia （score of 1）; number of coronary arteries （2 branches, score of 2; 〉 3 branches, score of 4）; body mass index （20-25 kg/m2, score of 2; 〉 25 kg/m2, score of 4）; percutaneous coronary intervention （score of 2）; and smoking （score of 3）. The HL test showed P ≥ 0.05 and area under the receiver operating characteristic curve ≥ 0.70. Conclusions We explored and quantified the risk factors for aspirin resistance. Our predictive model showed good calibration and discriminative power and therefore a good foundation for the further study of patients undergoing anti-platelet therapy.

Seroprevalence of anti-HAV among patients with chronic viral liver disease

AIM:To investigate the current seroprevalence of hepatitis A virus(HAV) antibodies in patients with chronic viral liver disease in Korea.We also tried to identify the factors affecting the prevalence of HAV antibodies. METHODS:We performed an analysis of the clinical records of 986 patients(mean age:49±9 years,714 males/272 females) with chronic hepatitis B virus(HBV) or hepatitis C virus(HCV) infection who had undergone HAV antibody testing between January 2008 and December 2009.RESULTS:The overall prevalence of IgG anti-HAV was 86.61%(854/986) in patients with chronic liver disease and was 88.13%(869/986) in age-and gendermatched patients from the Center for Health Promotion.The anti-HAV prevalence was 80.04%(405/506) in patients with chronic hepatitis B,86.96%(20/23) in patients with chronic hepatitis C,93.78%(422/450) in patients with HBV related liver cirrhosis,and 100%(7/7) in patients with HCV related liver cirrhosis.The anti-HAV prevalence according to the decade of age was as follows:20s(6.67%) ,30s(50.86%) ,40s(92.29%) ,50s(97.77%) ,and 60s(100%) .The antiHAV prevalence was significantly higher in patients older than 40 years compared with that in patients younger than 40 years of age.Multivariable analysis showed that age≥40 years,female gender and metropolitan cities as the place of residence were independent risk factors for IgG anti-HAV seropositivity. CONCLUSION:Most Korean patients with chronic liver disease and who are above 40 years of age have already been exposed to hepatitis A virus.

Anti-hepatitis A seroprevalence among chronic viral hepatitis patients in Kelantan,Malaysia

AIM:To determine the seroprevalence of anti-hepatitis A virus (HAV) antibodies in patients with chronic liver disease (CLD) and to justify the need for hepatitis A vaccination.METHODS:Patients (n=119) were enrolled between July and September 2009.The diagnosis of CLD was based on the presence of viral markers for more than 6 mo.The diagnosis of liver cirrhosis was based on clinical,biochemical and radiological profiles.Patient serum was tested for anti-HAV IgG.RESULTS:The overall anti-HAV seroprevalence was 88.2%.The aetiology of CLD was hepatitis B in 96 patients (80.7%) and hepatitis C in 23 patients (19.3%).Mean age was 44.4 ± 14 years.Patients were grouped according to age as follows:24 (20.2%) patients in the 21-30 years age group,22 (18.5%) in the 31-40 years age group,31 (26.1%) in the 41-50 years age group,23(19.3%) in the 51-60 years age group and 19 (16.0%) patients aged greater than 60 years,with reported seroprevalences of 66.7%,95.5%,93.5%,91.3% and 94.7%,respectively.There was a marked increase of seroprevalence in subjects older than 30 years (P=0.001).CONCLUSION:Our study demonstrated that patients aged greater than 30 years of age were likely to have natural immunity to hepatitis A.Therefore,hepatitis A vaccination may not be routinely required in this age group.

Drug Therapy Monitoring in Patients with Type 2 Diabetes and Hypertension

The aim of this paper is to detect, prevent and resolve DRP （drug-related problems） and NOM （negative outcomes associated with medication） in hospitalized patients with DM2 （type 2 diabetes） with HTN （hypertension） in a tertiary care clinic. Descriptive cross-sectional interventional study is used. DTM （drug therapy monitoring） was conducted in 73 patients using data obtained from clinical histories and interviews. NOM were detected based on symptoms and laboratory test results. The statistical significance was 0.05. It can be found that 23 DRP were detected, primarily in the category ＂likelihood of adverse effects＂ （30.43%） causing NOM in the ＂non-quantitative safety problem＂ category. The NOM detected were related to safety （62%）, effectiveness （24.5%） and necessity （13.5%）. Of the 68.57% of pharmacist interventions accepted, 48.57% were resolved and 20% were not resolved. A simple linear correlation （r = -0.34） analysis indicated a weak association between patient age and severity ofNOM. DTM made it＇possible to detect suspected DRP and NOM, which were then prevented or resolved, improving the control of HTN and DM2 and helping ensure better drug therapy outcomes for patients.

Is hyperhomocysteinemia relevant in patients with celiac disease?

AIM： TO investigate whether this might be related to the presence of hyperhomocysteinemia. METHODS： From January 1998 to December 2008, we evaluated the presence of hyperhomocysteinemia in a series of 165 adult celiac disease （CD） patients （138 females and 27 males, mean age 43 years）.RESULTS： Hyperhomocysteinemia was evident in 32 patients （19.3%）, although most of them had moderate levels （mean value 25 mcg/ml; range 15-30）. Only one patient had a history of myocardial infarction （heterozygosis for N5-N10-metil tetrahydrofolate reductase mutation）. CONCLUSION： The systematic assessment of hyperhomocysteinemia seems, at present, unjustified in CD patients.

POLYMORPHISM OF ANGIOTENSIN I TYPE 1 RECEPTOR GENE IN ELDERLY PATIENTS WITH ESSENTIAL HYPERTENSION

Objective To detect the A/C1165 polymorphism of angiotensin Ⅱ type Ⅰ receptor (AT1-R)gene in essential hypertensive elderly. Methods The A/C1166 polymorphism of AT1-R gene was assessed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in a case-control study of 87 essential hypertensive elders (EH) and 55 normolensive elders (NT). Results The genotype frequencies of AA, AC, CC were 0 .805 , 0.161, 0 .034 in EH group and 0 .927 ,0 .073 ,0 .000 in NT group respectively. The frequency of C61166 allele was higher in EH group (0.115) than in NT group (0 .036 )(P<0 .05 ). Conclusion The resultsindicate that A/C1166 polymorphism of AT1-R gene may be associated with essential hypertension in elderly.

RELATION OF HYPERTENSION TO DIABETIC NEPHROPATHY IN PATIENTS WITH NON-INSULIN-DEPENDENT DIABETES MELLITUS—A PAIR-MATCHED CASE-CONTROL STUDY

To assess the role of hypertension and family history of hypertensio n in the development of nephropathy in patients with non insulin dependent dia betes mellitus (NIDDM).Methods. A retrospective analysis was done on 2 groups of NIDDM patients, one g roup without proteinuria (urine protein< 300mg/24h, n=106) and the other group w ith proteinuria (urine protein≥500mg/24h, n=106). The 2 groups were matched by age(≤±3yrs), sex, ethnic and resident place. Some information of these subject s including demographic; history of disease, family history of diseases, lifesty le and behavior style variables was obtained by questionnaire; some variables w ere measured, including systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), quantity of protein in 24h urine. Then condi tional logistic regression analysis was performed.Results. Some factors, including history of hypertension, longer duration of hy pertension, higher levels of the past highest SBP and DBP, were independently as sociated with the occurrence risk of diabetic nephropathy (DN). Their correspond ing odd ratios (OR) with 95% confidence intervals (CI) were 2.00(1.17～3.43), 1 .25(1.08～1.46), 1.38(1.15～1.66), and 1.33(1.09～1.62) respectively, but family history of hypertension was not significantly associated with the development o f DN. When the above mentioned relations were respectively adjusted by some pos sible confounding factors, they still existed.Conclusions. History of hypertension, longer duration of hypertension, higher l evels of the past highest SBP and DBP are independent risk factors for DN in Chi nese NIDDM patients.

Effect of coronary artery revascularization on in-hospital outcomes and long-term prognoses in acute myocardial infarction patients with prior ischemic stroke

Objective To investigate whether coronary artery revascularization therapies （CART）, including percutaneous coronary intervention （PCI） and coronary artery bypass grafting （CABG）, can improve the in-hospital and long-term outcomes for acute myocardial infarction （AMI） patients with prior ischemic stroke （IS）. Methods A total of 387 AMI patients with prior IS were enrolled consecutively from January 15, 2005 to December 24, 2011 in this cohort study. All patients were categorized into the CART group （n = 204） or the conservative medications （CM） group （n = 183）. In-hospital cardiocerebral events and long-term mortality of the two groups after an average follow-up of 36 months were recorded by Kaplan-Meier survival curves and compared by Logistic regression and the Cox regression model. Results The CART patients were younger （66.5 ± 9.7 years vs. 71.7 ± 9.7 years, P 〈 0.01）, had less non-ST segment elevation myocardial infarction （11.8% vs. 20.8%, P = 0.016） and more multiple-vascular coronary lesions （50% vs. 69.4%, P = 0.031）. The hospitalization incidence of cardiocerebral events in the CART group was 9.3% while 26.2% in the CM group （P 〈 0.01）. CART significantly reduced the risk of in-hospital cardiocerebral events by 65% [adjusted odds ratio （OR） = 0.35, 95% CI： 0.13-0.92]. By the end of follow-up, 57 cases （41.6%） died in CM group （n = 137） and 24 cases （12.2%） died in CART group （n = 197）. Cox regression indicated that CART decreased the long-term mortality by 72% [adjusted hazard ratio （HR） = 0.28, 95% CI： 0.064）.46], while categorical analysis indicated no s{gnificant dif- ference between PCI and CABG. Conclusions CART has a significant effect on improving the in-hospital and long-term prognoses for AMI patients with prior IS.

Role of Dongchongxiacao (Cordyceps) in prevention of contrast-induced nephropathy in patients with stable angina pectoris

OBJECTIVE： To study the preventative effects of Dongchongxiacao （Cordyceps） on contrast-induced nephropathy （CIN） in patients with stable angina pectoris （SAP）. METHODS： One-hundred and three SAP inpatients were divided randomly into two groups： basic treat- ment （n=51） and Dongchongxiacao （Cordyceps） treatment （n=52）; corbrin capsules （3 g; t.d.s.） were used 3 days before angioplasty and 3 days after an- gioplasty）. Serum creatinine （Scr） was assessed at the time of hospital admission and 1, 2, and 3 days after angioplasty. Values of kidney injury mole- cule-1 （KIM-1）, neutrophil gelatinase-associated li- pocalin （NGAL） and interleukin （IL） 18 in the kidney were detected before angioplasty and 1 day after angioplasty in the patients of both groups. The prevalence of CIN between the two groups was then compared. RESULTS： CIN occurred in 9 of 103 patients （8.74%）. The prevalence of CIN in the Dongchongxiacao （Cordyceps） treatment group was lower than that of the basic treatment group （5.77% vs 11.76%） but the difference was not significant （P〉0.05）. The post-procedure mean peak of Scr, post-procedure increase in Scr levels from baseline, and urine levelsof KIM-1, NGAL and IL18 after the procedure in the Dongchongxiacao （Corclyceps） treatment group were significantly lower than those in the basic treatment group （P〈0.05）. CONCLUSION： Prophylactic treatment with Dongchongxiacao （Cordyceps） in SAP patients who undergo coronary angiography or coronary inter- vention could prevent contrast-induced renal im- pairment.

Correlation between Traditional Chinese Medicine symptom patterns and serum concentration of zinc,iron,copper and magnesium in patients with hepatitis B and associated liver cirrhosis

OBJECTIVE:To investigate the correlation between the patterns of Traditional Chinese Medicine(TCM)syndromes and the serum concentration of zinc,iron,copper and magnesium of patients with chronic hepatitis B(CHB) and hepatitis B virus(HBV)-induced liver cirrhosis.METHODS:A total of 86 patients were included in the study between March 1,2009 and January 1,2010.All were diagnosed with CHB or HBV-induced liver cirrhosis according to the diagnosis standard of the Chinese Medical Association.Fasting serum concentrations of zinc,iron,copper and magnesium were measured.Patients were classified into different patterns of TCM symptoms according to TCM theory and clinical experience.RESULTS:In the HBV-induced liver cirrhosis group,the mean zinc concentration in patients with the TCM pattern of stagnation of fluid-Dampness was lower than that in patients with obstruction of collaterals by Blood stasis(P < 0.034).In the CHB group,the mean magnesium concentration in patients with toxic Heat flourishing was significantly lower than that in those with Damp-Heat in the Liver and Gallbladder,and those with Liver depression and Spleen deficiency(P < 0.021).The concentrations of iron and copper showed little difference among the different TCM symptom patterns.CONCLUSION:The serum zinc and magnesium concentrations correlated with certain TCM patterns of symptoms in patients with HBV-induced liver cirrhosis and CHB.It may be helpful to interpret the pathogenic change in the TCM symptom patterns in liver cirrhosis and CHB,and also to conduct clinical treatment of the diseases based on identified TCM patterns.
