Development of an HIV/STI and partner violence health promotion intervention for abused US Virgin Islands women.

Women in the US Virgin Islands (USVI) experience intimate partner violence (IPV) and human immunodeficiency virus (HIV) at disproportionate rates compared to women on the US mainland. Women in violent relationships report experiencing controlling behaviours that decrease their ability to negotiate for sex using condoms or to prevent unwanted pregnancies. Though several evidence-based interventions exist to prevent either IPV or HIV, few address them through an integrated health promotion approach or attend to particular USVI cultural mores. This article describes the systematic development of a theory based, culturally tailored, integrated health promotion intervention that addresses IPV and HIV among USVI women experiencing abuse. The process included: (i) identifying and integrating evidence-based health promotion interventions, (ii) conducting formative research using focus groups, (iii) synthesizing focus group data to inform intervention development and (iv) developing a culturally and linguistically appropriate intervention specific to the needs and concerns of USVI women. The Empowered Sisters Project: Making Choices Reducing Risks (ESP) was developed through this research. ESP is a three-session health promotion curriculum focussed on enhancing sexual health and safety among women experiencing abuse. The ESP intervention components included promoting condom use, increasing IPV and HIV knowledge and developing a personalized safety plan. Health professionals facilitated individual intervention sessions using culturally tailored visual media and scripts. This program focussed on experiences of women living in the USVI and has implications for utility across the Caribbean diaspora.

Multiple Dimensions and Correlates of Fatigue in Individuals on Hemodialysis.

This study examined the severity, pattern, and correlates of fatigue among adults undergoing hemodialysis. Measures included the Piper Fatigue Scale (PFS-12), Patient-Reported Outcomes Measurement Information System (PROMIS) - Fatigue, Charlson Comorbidity Index, and Six-Minute Walk Test (6MWT). Patients were excluded if mobility or cardiovascular issues prevented conducting the 6MWT. Participants were 86 cognitively intact adults (M = 61.7 years, SD = 13.81), predominantly male (58.1%), and African American (48.8%), with 80% reporting fatigue in the week prior to hemodialysis. Significant increases were noted in sensory and cognitive fatigue from pre- to post-dialysis, while the 6MWT distance decreased significantly pre- to post-dialysis. Factors significantly associated with pre-dialysis fatigue included low hemoglobin, younger age, and living with someone else, while comorbidities and dialysis inadequacy were trending to significant associations with fatigue.

Beauty for Ashes: A Church-Based Diabetes Care Program.

The pilot study described here was a test of interventions designed to enhance long-term disease management of African-Americans with type 2 diabetes in faith-based organizations. A quasi-experimental design based on 46 participants was used comparing three interventions: guided imagery, group counseling, and routine care. Unexpectedly, the number of self-reported hypoglycemic episodes significantly increased in the Rational Emotive Behavioral Therapy (REBT) group, depressive symptoms significantly increased in the guided imagery group, and the mean hemoglobin A1c values did not significantly differ for any group. In future research, the authors will incorporate an interim step investigating the theory of integration (Hernandez, Antone, & Cornelius, 1999) to increase the explanatory power in assessing treatment effects of African-Americans in faith-based organizations.

A Church-Based Diabetes Care Survey in St. Thomas, U.S. Virgin Islands.

Forty-eight (N = 48) African-Caribbeans participated in a church-based diabetes care survey in St. Thomas, U.S. Virgin Islands. The purpose of this pilot study was to determine whether integration was a significant predictor of depressive symptoms and glycemic control in persons with type 2 diabetes among African-Caribbeans in faith-based organizations (FBO), controlling for demographic variables. Data were collected on measures of integration of diabetes, acceptance, depressive symptoms, number of hypoglycemic episodes, hemoglobin Alc, and demographic characteristics. The majority of subjects were female. Acceptance and depression were negatively correlated, and acceptance and integration were positively correlated. Depression and number of mild hypoglycemic episodes were also positively correlated. Surprisingly, integration was not significantly related to hemoglobin Alc, number of hypoglycemic episodes, and depressive symptoms. Implications of these findings are presented.

Factors Associated with African-American Women's Decisions to Participate in Genetic Research.

The purpose of this study was to determine the factors that are associated with African-American (AA) women's decisions to participate in genetic research. Using a descriptive correlational design, a convenience sample of African-American women (age ≥ 40) was recruited from various locations in the Midwest. During semi-structured interviews, demographics, psychological factors, knowledge of and attitudes toward genetics were collected. Of the 98 women (mean age 53), 66% indicated that they were unwilling to participate, despite having positive attitudes. Correlations were found between genetic knowledge and attitudes toward genetics (r = .35, p = .001), and decision-making to participate and attitudes toward genetics (r = .40, p = .001). Data revealed decisions were largely associated with their lack of knowledge and resulting perceptions. Efforts should be made to inform African-American women about the benefits of the new science through planned, culturally specific, and sensitive interventions that incorporate genetic and health literacy programs.

Effectiveness of an Algorithmic Approach to Ventilator Withdrawal at the End of Life: A Stepped Wedge Cluster Randomized Trial.

Background: The transition to spontaneous breathing puts patients who are undergoing ventilator withdrawal at high risk for developing respiratory distress. A patient-centered algorithmic approach could standardize this process and meet unique patient needs because a single approach (weaning vs. one-step extubation) does not capture the needs of a heterogenous population undergoing this palliative procedure. Objectives: (1) Demonstrate that the algorithmic approach can be effective to ensure greater patient respiratory comfort compared to usual care; (2) determine differences in opioid or benzodiazepine use; (3) predict factors associated with duration of survival. Design/Settings/Measures: A stepped-wedge cluster randomized design at five sites was used. Sites crossed over to the algorithm in random order after usual care data were obtained. Patient comfort was measured with the Respiratory Distress Observation Scale© (RDOS) at baseline, at ventilator off, and every 15-minutes for an hour. Parenteral morphine and lorazepam equivalents from the onset of the process until patient death were calculated. Results: Usual care data n = 120, algorithm data n = 48. Gender and race were evenly distributed. All patients in the usual care arm underwent a one-step ventilator cessation; 58% of patients in the algorithm arm were weaned over an average of 18 ± 27 minutes as prescribed in the algorithm. Patients had significantly less respiratory distress in the intervention arm (F = 10.41, p = 0.0013, effective size [es] = 0.49). More opioids (t = -2.30, p = 0.023) and benzodiazepines (t = -2.08, p = 0.040) were given in the control arm. Conclusions: The algorithm was effective in ensuring patient respiratory comfort. Surprisingly, more medication was given in the usual care arm; however, less may be needed when distress is objectively measured (RDOS), and treatment is initiated as soon as distress develops as in the algorithm. Clinical Trial Registration number: NCT03121391.

Biologic measures as epidemiological indicators of risk for the development of hypertension in an African American adolescent population.

UNLABELLED: Globally, the health disparity of hypertension is disproportionately greater within the African American population and develops at an earlier age. Elevated and continuous interaction of biologic measures during adolescence may be precursors and indicators of risk for blood pressure changes and the subsequent development of adult essential hypertension. The purpose of this study was to describe (1) the prevalence of biologic measures of risk of hypertension, specifically family history of hypertension, prehypertension, elevated salivary cortisol, and hyperresponsive cortisol and cardiovascular reactivity, and (2) the gender difference in the prevalence of biologic risk factors of hypertension. SUBJECTS AND METHOD: This was an exploratory descriptive design with a nonrandom purposive sample. Participants (N = 106) were high school, African American adolescents, aged 14 to 18 years. Data, including family history of hypertension, resting blood pressure, and blood pressure and cortisol levels before and after induced physiologic stress by cold water hand immersion, were measured. RESULTS: One hundred six African American participants (49 males and 57 females) completed the study. Data described that 71% had a positive family history of hypertension. Overall, the resting blood pressures were 120 mm Hg for systolic and 68 mm Hg for diastolic. Forty-one percent of the patients had prehypertensive blood pressures; 86% had elevated cortisol; 49% had hyperresponsive blood pressure reactivity; and 35% had cortisol hyperresponsivity. Excluding ethnicity, 65% had 3 or more biologic measures of risk of hypertension. Statistically significant gender differences included male systolic pressure and number of males with prehypertension. CONCLUSION: This study provides evidence of the high prevalence of multiple physiologic biologic measures of risk of hypertension factors within a vulnerable population. The continuous interaction of biologic measures over time may increase the susceptibility and risk of essential hypertension development and supports the development of appropriate physiologically based behavioral interventions.

The Digital Divide and urban older adults.

Computers and the Internet offer older adults opportunities and resources for independent living. However, many urban older adults do not use computers. This study examined the demographic, health, and social activities of urban older adults to determine variables that might predict the use and nonuse of computers in this population. A secondary data analysis was performed using the 2001 Detroit City-Wide Needs Assessment of Older Adults (n = 1410) data set. Logistic regression was used to explore potential differences in predictor variables between computer users and nonusers. Overall, computer users were younger (27%), had a higher level of education, were more likely to be employed, had an annual income greater than $20,000, and were healthier and more active than nonusers. They also were more likely to have memberships in community organizations and do volunteer work. Preferred computer activities included conducting Internet searches, playing games, writing, and communicating with family members and friends. The results suggest significant differences in demographic and health-related characteristics between computer users and nonusers among urban older adults. Although about a quarter of participants in this study used computers, the Digital Divide continues to exist in urban settings for scores of others.

Association of Psychosocial Symptoms, Blood Pressure, and Menopausal Status in African-American Women.

African-American women have disproportionate rates of hypertension that can be further complicated as they transition through menopause. Stress, coupled with depression and hypertension in perimenopausal African-American women has not been fully explored. This study examines the associations of stress, depression, and social support on systolic blood pressure (SBP) among a sample of 184 perimenopausal African-American women. We used descriptive statistics, Pearson's correlation, and logistic regression to analyze data stratified by menopausal status (perimenopausal or menopausal) and SBP status (<130 mmHg vs. >130 mmHg). Women classified as menopausal reported higher levels of stress and depressive symptoms, and lower levels of social support. Age, body mass index (BMI), health insurance, and perceived health status were significant predictors of SBP in menopausal women. Stress, depression, and social support did not play a role in SBP. It is necessary that future research focus on reducing cardiovascular risk include addressing menopausal health.

Comparison of EMLA and Diclofenac on Reduction of Pain and Phlebitis Caused by Peripheral IV Catheter: A Randomized-Controlled Trial Study.

Peripheral venous catheters (PVC) are often used to provide hydration, medications, and blood products when the length of therapy is expected to be less than 1 week. Pain and phlebitis are frequent complications of PVC. Diclofenac and EMLA have been used to minimize these adverse effects; however, conflicting results have been reported regarding which has better outcomes. This double-blind, randomized controlled trial was conducted to compare the efficacy of EMLA and Diclofenac (TDP) in attenuating PVC pain and phlebitis. The inpatient setting was chosen because of the higher frequency of PVC insertions, allowing for a sufficient sample size. One hundred fifty-four subjects were randomly assigned to three groups: EMLA patch (n = 61), a TDP patch (n = 50), or a patch with lubricant gel (n = 46) as a placebo. The pain was measured by Visual Analogue Scale (VAS). Phlebitis was examined based on Boxter criteria in intervals of 6, 12, 18, 24, and 48 hours after PVC insertion. The mean score of VAS was 41.86 ± 22.49 for the control, 39.40 ± 21.60 for TDP, and 38.77 ± 23.28 for the EMLA group, with no significant differences in pain severity between the three groups. The rate of phlebitis in the group with EMLA was significantly higher than the other two groups at 6, 12, and 18 hours (p = 0.02, p = 0.003 and p = 0.04, respectively). In all interval times, the rate of phlebitis in the TDP group was significantly lower than the other groups. Compared with men, women experienced higher rate of phlebitis and intensity of PVC pain. EMLA and TDP had similar analgesic effects, but phlebitis was less frequently observed with TDP, suggesting TDP as a potential medication for reducing pain and phlebitis before PVC insertion.

Trajectory of Dyspnea and Respiratory Distress among Patients in the Last Month of Life.

BACKGROUND: The trajectory of dyspnea has been reported among patients approaching the end of life. However, patients near death have been dropped from longitudinal studies or excluded altogether because of an inability to self-report; proxy estimates have been reported. It is not known whether dyspnea or respiratory distress remains stable, escalates, or abates as patients reach last days. OBJECTIVE: Determine trajectory of dyspnea (self-reported) and respiratory distress (observed) among patients who were approaching death. DESIGN: A prospective, repeated-measures study of dyspnea/respiratory distress among a sample of hospice patients was done. Measures were collected at each patient encounter from hospice enrollment until patient death. MEASUREMENTS: Dyspnea was measured in response to "Are you short of breath?" and using the numeric rating scale anchored at 0 and 10. Nurses measured respiratory distress with the Respiratory Distress Observation Scale (RDOS). Patient consciousness (Reaction Level Scale), nearness to death (Palliative Performance Scale), diagnoses, and demographics were recorded. Data for the 30-day interval before death were analyzed. RESULTS: The sample was 91 patients who were female (58%) and Caucasian (83%) with dementia (32%), heart failure (26%), and cancer (13%). RDOS increased significantly from mild distress 30 days before death to moderate/severe distress on the day of death (F = 10.8, p < 0.0001). Distress was strongly correlated with nearness to death (r = -0.97, p < 0.0001) and consciousness (r = 0.97, p < 0.0001). CONCLUSIONS: Respiratory distress escalated in the last days. Inability to self-report raises care concerns about under-recognition and under-treatment of respiratory distress.

The association of low birth weight and physiological risk factors of hypertension in African American adolescents.

UNLABELLED: Low birth weight (LBW) has been associated with increased blood pressure and the development of cardiovascular disease including hypertension. Elevated blood pressure, cortisol, and hyperresponsiveness during physiologic stress may function as hypertension biological markers. We examined the association of blood pressure and cortisol levels during induced physiologic stress with LBW in an African American adolescent population (n = 106). METHODS AND RESULTS: Birth weight was obtained from parents. Blood pressure and cortisol levels were measured at rest and in response to an induced physiological stressor. Compared with normal birth weight group (n = 73), the LBW group (n = 33) demonstrated elevated (+4 mm Hg) diastolic pressure (P = .002) and cortisol hyperresponsiveness (P = .05). Seventy-nine percent of LBW adolescents had elevated blood pressure and/or cardiovascular reactivity (P = .04), and 39% had elevated blood pressures. CONCLUSIONS: Low birth weight African American adolescents demonstrated physiological risk factors for hypertension, and these findings add support to the association between LBW and the development of hypertension.

Measuring asthma self-management knowledge in adults.

PURPOSE: To present the development and psychometrics of a brief asthma self-management questionnaire for adults incorporating the five content areas considered essential for asthma self-management by the National Asthma Education and Prevention Program. DATA SOURCES: After development of the criterion-referenced questionnaire, determination of content validity, pilot testing, and revision, the questionnaire was administered to 305 adults with asthma. CONCLUSIONS: After exploratory principal component factor analysis, the final 24-item questionnaire had a reliability of .69, close to the preferred reliability of .70. IMPLICATIONS: The questionnaire is recommended for assessing self-management knowledge in clinical settings and for evaluation of asthma education programs.

Risk For Postpartum Depression Among Immigrant Arabic Women in the United States: A Feasibility Study.

INTRODUCTION: Postpartum depression (PPD) affects approximately 14% of women in the United States and 10% to 37% of Arabic women in the Middle East. Evidence suggests that immigrant women experience higher rates, but information on PPD among immigrant women of Arabic descent in the United States is nonexistent. METHODS: A cross-sectional descriptive feasibility study was conducted to assess the practicality of implementing a larger proposed research study to examine predictors of PPD in US immigrant women of Arabic descent residing in Dearborn, Michigan. Fifty women were recruited from an Arab community center and completed demographic data, the Arabic version of the Edinburgh Postpartum Depression Scale (EPDS), and the Postpartum Depression Predictors Inventory-Revised (PDPI-R). RESULTS: Among participants, 36% were considered at high risk for developing PPD. Lack of social support, antenatal anxiety, antenatal depression, maternity blues (feeling depressed during the first 4 weeks postpartum), and life stress were significantly related to risk for PPD. Multiple regression analysis revealed that social support (t = -3.77, P < .0001) and maternity blues (t = 2.19, P = .03) were the only significant predictors for postpartum depressive symptoms. DISCUSSION: Findings of this study describe the prevalence of PPD in a sample of US immigrant women of Arabic descent and support the feasibility of a larger and more in-depth understanding of their immigration and acculturation experiences. Study participants reported high risk for PPD. Maternity blues and lack of social support were significant predictors to the risk for PPD. Future research tailored to this minority group is recommended.

Self-Efficacy and Blood Pressure Self-Care Behaviors in Patients on Chronic Hemodialysis.

This study examined the effects of an educative, self-regulation intervention on blood pressure self-efficacy, self-care outcomes, and blood pressure control in adults receiving hemodialysis. Simple randomization was done at the hemodialysis unit level. One hundred eighteen participants were randomized to usual care ( n = 59) or intervention group ( n = 59). The intervention group received blood pressure education sessions and 12 weeks of individual counseling on self-regulation of blood pressure, fluid, and salt intake. There was no significant increase in self-efficacy scores within ( F = .55, p = .46) or between groups at 12 weeks ( F = 2.76, p = .10). Although the intervention was not successful, results from the total sample ( N = 118) revealed that self-efficacy was significantly related to a number of self-care outcomes including decreased salt intake, lower interdialytic weight gain, increased adherence to blood pressure medications, and fewer missed hemodialysis appointments. Increased blood pressure self-efficacy was also associated with lower diastolic blood pressure.

Text Messaging to Improve Hypertension Medication Adherence in African Americans From Primary Care and Emergency Department Settings: Results From Two Randomized Feasibility Studies.

BACKGROUND: Hypertension (HTN) is an important problem in the United States, with an estimated 78 million Americans aged 20 years and older suffering from this condition. Health disparities related to HTN are common in the United States, with African Americans suffering from greater prevalence of the condition than whites, as well as greater severity, earlier onset, and more complications. Medication adherence is an important component of HTN management, but adherence is often poor, and simply forgetting to take medications is often cited as a reason. Mobile health (mHealth) strategies have the potential to be a low-cost and effective method for improving medication adherence that also has broad reach. OBJECTIVE: Our goal was to determine the feasibility, acceptability, and preliminary clinical effectiveness of BPMED, an intervention designed to improve medication adherence among African Americans with uncontrolled HTN, through fully automated text messaging support. METHODS: We conducted two parallel, unblinded randomized controlled pilot trials with African-American patients who had uncontrolled HTN, recruited from primary care and emergency department (ED) settings. In each trial, participants were randomized to receive either usual care or the BPMED intervention for one month. Data were collected in-person at baseline and one-month follow-up, assessing the effect on medication adherence, systolic and diastolic blood pressure (SBP and DBP), medication adherence self-efficacy, and participant satisfaction. Data for both randomized controlled pilot trials were analyzed separately and combined. RESULTS: A total of 58 primary care and 65 ED participants were recruited with retention rates of 91% (53/58) and 88% (57/65), respectively. BPMED participants consistently showed numerically greater, yet nonsignificant, improvements in measures of medication adherence (mean change 0.9, SD 2.0 vs mean change 0.5, SD 1.5, P=.26), SBP (mean change -12.6, SD 24.0 vs mean change -11.3, SD 25.5 mm Hg, P=.78), and DBP (mean change -4.9, SD 13.1 mm Hg vs mean change -3.3, SD 14.3 mm Hg, P=.54). Control and BPMED participants had slight improvements to medication adherence self-efficacy (mean change 0.8, SD 9.8 vs mean change 0.7, SD 7.0) with no significant differences found between groups (P=.92). On linear regression analysis, baseline SBP was the only predictor of SBP change; participants with higher SBP at enrollment exhibited significantly greater improvements at one-month follow-up (ß=-0.63, P<.001). In total, 94% (51/54) of BPMED participants agreed/strongly agreed that they were satisfied with the program, regardless of pilot setting. CONCLUSIONS: Use of text message reminders to improve medication adherence is a feasible and acceptable approach among African Americans with uncontrolled HTN. Although differences in actual medication adherence and blood pressure between BPMED and usual care controls were not significant, patterns of improvement in the BPMED condition suggest that text message medication reminders may have an effect and fully powered investigations with longer-term follow-up are warranted.

Influence of coagulation factor, vitamin K epoxide reductase complex subunit 1, and cytochrome P450 2C9 gene polymorphisms on warfarin dose requirements.

INTRODUCTION: The primary objective of this study was to determine whether variability in warfarin dose requirements is determined by common polymorphisms in genes whose products are involved in the pharmacodynamics and pharmacokinetics of warfarin, namely, the coagulation factors, vitamin K epoxide reductase complex subunit 1 (VKORC1), and cytochrome P450 (CYP) 2C9. METHODS: Patients (N = 350) receiving stable doses of warfarin at 3 consecutive visits were enrolled, and a deoxyribonucleic acid sample was collected. Samples were genotyped for polymorphisms in the factor II, factor VII, factor X, VKORC1, and CYP2C9 genes. A stepwise linear regression analysis was used to determine the independent effects of genetic and nongenetic factors on mean warfarin dose requirements. RESULTS: Variables associated with lower warfarin dose requirements were VKORC1 3673 AA genotype (P < .0001), VKORC1 3673 GA genotype (P < .0001), 1 variant CYP2C9 allele (P < .0001), 2 variant CYP2C9 alleles (P = .0004), increasing age (P = .0005), concomitant CYP2C9 inhibitors (P = .0005), and goal international normalized ratio (P = .01). Variables associated with higher warfarin dose requirements were weight (P < .0001), current smoker status (P = .0009), mean international normalized ratio (P = .001), concomitant CYP2C9 inducers (P = .006), factor X insertion/deletion genotype (P = .01), factor X insertion/insertion genotype (P = .04), factor VII deletion/deletion genotype (P = .04), and calculated vitamin K intake (P = .05). The linear regression model explained 51.4% of the variability in warfarin dose requirements. CONCLUSION: Polymorphisms in warfarin drug target and metabolizing enzyme genes, in addition to nongenetic factors, were important determinants of warfarin dose requirements.

Discordant beta-blocker effects on clinic, ambulatory, resting, and exercise hemodynamics in patients with hypertension.

STUDY OBJECTIVES: To determine the correlation between ambulatory and clinic blood pressure in assessing antihypertensive response to beta-blockade, to test whether blood pressure response to metoprolol is associated with the heart rate response, and to determine whether exercise and resting heart rate responses to metoprolol are correlated. DESIGN: Post hoc analysis of a prospective cohort study. SETTING: University-affiliated general clinical research center. PATIENTS: Fifty-one patients aged 35-65 years with uncomplicated hypertension. Intervention. All patients received metoprolol at a dosage titrated to achieve a diastolic blood pressure below 90 mm Hg. MEASUREMENTS AND MAIN RESULTS: Clinic and 24-hour ambulatory blood pressure measurements were obtained and exercise treadmill testing was performed before and after metoprolol treatment. Based on ambulatory blood pressure data, 24 patients (47%) responded (defined as at least a 10% reduction in diastolic blood pressure) to metoprolol compared with 36 patients (71%) based on clinic blood pressure data (p=0.027). Clinic blood pressure was associated with a 67% false-positive rate (responsive blood pressure by clinic data that was actually nonresponsive by ambulatory data). Blood pressure responders and nonresponders exhibited similar reductions in exercise heart rate (24% and 23%, p=0.74). However, responses to metoprolol measured by exercise heart rate versus resting heart rate were not significantly correlated (r=0.24, p=0.105). CONCLUSION: Reliance on clinic blood pressure or resting heart rate for making beta-blocker treatment decisions may yield less than optimal assessment of the antihypertensive response or degree of beta-blockade.

Violence and abuse of internally displaced women survivors of the 2010 Haiti earthquake.

OBJECTIVES: Limited research following disasters suggests that internally displaced women are disproportionately vulnerable to violence and abuse. An interdisciplinary collaborative of researchers and practitioners in Haiti, the US Virgin Islands, and the US Mainland investigated gender-based violence (GBV) pre- and post-earthquake and health outcomes among Haitian women living in tent cities/camps following the 2010 earthquake. METHODS: A comparative descriptive correlational design using culturally sensitive and language appropriate computer-assisted interviews of 208 internally displaced women 2011-2013. RESULTS: Found high rates of violence and abuse both before (71.2 %) and after (75 %) p = 0.266, the earthquake primarily perpetrated by boy friends or husbands. Significantly more mental and physical health problems were reported by abused than non-abused women. The majority (60-78 %) of abused women did not report personal or community tolerance for violence and abuse, but acknowledged a community context of limited involvement. CONCLUSIONS: Coordinated planning and implementation of needed interventions are essential to provide a balanced approach to the care of displaced women after natural disasters with sensitivity to the abusive experiences of many women both before and after the disasters.

beta-Adrenergic receptor polymorphisms and responses during titration of metoprolol controlled release/extended release in heart failure.

OBJECTIVE: beta-Blockers require careful initiation and titration when used in patients with heart failure. Some patients tolerate beta-blocker therapy initiation without difficulty, whereas in other patients this period presents clinical challenges. We tested the hypothesis that polymorphisms at codons 389 (Arg389Gly) and 49 (Ser49Gly) of the beta(1)-adrenergic receptor would be associated with differences in initial tolerability of beta-blocker therapy in patients with heart failure. We also tested whether polymorphisms in the beta(2)-adrenergic receptor, G-protein alpha s subunit (G(s)alpha), and cytochrome P450 (CYP) 2D6 genes or S-metoprolol plasma concentrations were associated with beta-blocker tolerability. METHODS: Sixty-one beta-blocker-naive patients with systolic heart failure were prospectively enrolled. Patients began taking 12.5 to 25 mg metoprolol controlled release/extended release with titration every 2 weeks (as tolerated) to 200 mg/d or the maximum tolerated dose over a period of 8 to 10 weeks. Decompensation was the composite of death, heart failure hospitalization, increase in other heart failure medications, or need to discontinue metoprolol. End points were assessed during the titration period. RESULTS: The overall rate of decompensation was not different between the codon 49 or 389 genotypes. However, a significantly greater percentage of patients with the Gly389 variant required increases in heart failure medications as compared with Arg389 homozygotes (48% versus 14%, respectively; P = .006). Similarly, patients with the Ser49 homozygous genotype were significantly more likely to require increases in concomitant heart failure therapy as compared with Gly49 carriers (41% versus 11%, respectively; P = .03). Neither CYP2D6 genotypes nor metoprolol pharmacokinetics differed between patients with and those without a decompensation event. There was no association between the beta(2)-adrenergic receptor or G(s)alpha polymorphisms with decompensated heart failure. CONCLUSIONS: Patients with the Gly389 variant and Ser49Ser genotype were significantly more likely to require increases in heart failure medications during beta-blocker titration and thus may require more frequent follow-up during titration.
