RESUMO

Aim: To assess the association between the CETP Taq1B and I405V polymorphisms with levels of lipoprotein subclasses in African-American (AA) men with and without Type 2 diabetes (T2DM). Patients & methods: AA men, over 30 years of age, with (n = 54) or without T2DM (n = 50), and not receiving lipid-lowering agents, underwent advanced lipid analysis and genotyping. Results & conclusion: In the total patient population Taq1B B2-allele carriers had significantly higher levels of large HDL subclasses (HDL-2b [p = 0.017] and HDL-L [p = 0.019]), lower levels of small-HDL subclasses (HDL-3a [p = 0.004] and HDL-3b [p = 0.031]), and lower levels of LDL subclasses (LDL-IVa [p = 0.012] and LDL-IIIb [p = 0.009]). The only significant genotype-diabetes interaction occurred with the HDL-2a subclass (p = 0.015). No statistically significant associations were seen with I405V genotype. Our observations of lower levels of small-HDL and higher levels of large-HDL suggest that a potentially important HDL subclass-CETP relationship exists.

RESUMO

Objective. To assess and compare interprofessional education (IPE) naive pharmacy and nursing student stereotypes prior to completion of an IPE activity. Methods. Three hundred and twenty-three pharmacy students and 275 nursing students at Mercer University completed the Student Stereotypes Rating Questionnaire. Responses from pharmacy and nursing students were compared, and responses from different level learners within the same profession also were compared. Results. Three hundred and fifty-six (59.5%) students completed the survey. Pharmacy students viewed pharmacists more favorably than nursing students viewed pharmacists for all attributes except the ability to work independently. Additionally, nursing students viewed nurses less favorably than pharmacy students viewed nurses for academic ability and practical skills. There was some variability in stereotypes between professional years. Conclusion. This study confirms the existence of professional stereotypes, although overall student perceptions of their own profession and the other were generally positive.

RESUMO

IMPORTANCE: Detailed, nationally representative data describing high-risk populations and circumstances involved in insulin-related hypoglycemia and errors (IHEs) can inform approaches to individualizing glycemic targets. OBJECTIVE: To describe the US burden, rates, and characteristics of emergency department (ED) visits and emergency hospitalizations for IHEs. DESIGN, SETTING, AND PARTICIPANTS: Nationally representative public health surveillance of adverse drug events among insulin-treated patients seeking ED care (National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance project) and a national household survey of insulin use (the National Health Interview Survey) were used to obtain data from January 1, 2007, through December 31, 2011. MAIN OUTCOMES AND MEASURES: Estimated annual numbers and estimated annual rates of ED visits and hospitalizations for IHEs among insulin-treated patients with diabetes mellitus. RESULTS: Based on 8100 National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance cases, an estimated 97,648 (95% CI, 64,410-130,887) ED visits for IHEs occurred annually; almost one-third (29.3%; 95% CI, 21.8%-36.8%) resulted in hospitalization. Severe neurologic sequelae were documented in an estimated 60.6% (95% CI, 51.3%-69.9%) of ED visits for IHEs, and blood glucose levels of 50 mg/dL (to convert to millimoles per liter, multiply by 0.0555) or less were recorded in more than half of cases (53.4%). Insulin-treated patients 80 years or older were more than twice as likely to visit the ED (rate ratio, 2.5; 95% CI, 1.5-4.3) and nearly 5 times as likely to be subsequently hospitalized (rate ratio, 4.9; 95% CI, 2.6-9.1) for IHEs than those 45 to 64 years. The most commonly identified IHE precipitants were reduced food intake and administration of the wrong insulin product. CONCLUSIONS AND RELEVANCE: Rates of ED visits and subsequent hospitalizations for IHEs were highest in patients 80 years or older; the risks of hypoglycemic sequelae in this age group should be considered in decisions to prescribe and intensify insulin. Meal-planning misadventures and insulin product mix-ups are important targets for hypoglycemia prevention efforts.

RESUMO

BACKGROUND: Medication history forms completed by patients are an essential part of the medication reconciliation process. OBJECTIVE: In a crossover prospective study, investigators compared the accuracy and acceptability of a "fill-in-the blank" medication history form (USUAL) to a customized form (CUSTOM) that contained a checklist of the 44 most frequently prescribed diabetes clinic medications. METHODS: The content of both forms was compared to a "gold-standard" medication list compiled by a clinical pharmacist who conducted a medication history and reviewed pharmacy profiles and medical chart. Subject preference and time to complete the forms were also determined. Accurate was defined as complete and correct (name, dose, and frequency) relative to the gold standard. RESULTS: A total of 77 subjects completed both forms. Complete list accuracy was poor; there was no difference in the accuracy between CUSTOM (6.5%) and USUAL (9.1%) (odds ratio [OR], 0.33; P = 0.62). Out of a total of 648 medications, subjects accurately listed 43.7% of medications on CUSTOM and 45.5% on USUAL (OR, 0.88; P = 0.41). The 44 medications on the checklist were more than twice as likely to be accurately reported using CUSTOM than with USUAL (OR, 2.1; P = 0.0002). More subjects preferred CUSTOM (65.7%) compared with USUAL (32.8%, P = 0.007). CONCLUSION: Medication self-report is very poor, and few subjects created an accurate list on either form. Subjects were more likely to report the drugs on the checklist using CUSTOM than when they used USUAL; however, there was no difference in the overall accuracy between CUSTOM and USUAL.

RESUMO

PURPOSE: The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, administration, dosage, place in therapy, and cost of extended-release exenatide are reviewed. SUMMARY: Regular-release exenatide has a half-life of 2.4 hours and is administered twice daily. In order to allow for once-weekly administration, exenatide was encapsulated in poly(lactic-co-glycolic acid) microspheres, a biodegradable polymer. After subcutaneous injection, the microspheres slowly degrade, and the drug is released. A single injection of extended-release exenatide reaches maximum plasma concentration after 4-8 hours and remains at therapeutic levels for 8-16 hours, depending on the dosage. Based on the pharmacokinetics of a single dose, researchers determined that 0.8- and 2-mg once-weekly doses were likely to maintain therapeutic levels in the serum. Patients who used extended-release exenatide monotherapy had significantly lower glycosylated hemoglobin (HbA1c) levels and lost more weight than those receiving sitagliptin or pioglitazone (p < 0.05). In combination with metformin, extended-release exenatide reduced HbA1c levels more than did insulin glargine. This new formulation reduced HbA1c levels by 1.5-1.9%, fasting blood glucose concentrations by 31-42 mg/dL, and weight by 2.3-3.7 kg. The most common adverse events were injection-site reactions and transient nausea. Postmarketing reports have described acute pancreatitis and acute necrotizing or hemorrhagic pancreatitis in patients treated with exenatide. The published average wholesale price for a one-month supply of extended-release exenatide 2 mg is $388. CONCLUSION: Extended-release exenatide taken once weekly is an effective second-line therapy for patients with type 2 diabetes who have not achieved glycemic goals with metformin alone.

RESUMO

PURPOSE: The objective of this project was to determine the amount and type of clinical skills and diabetes education provided by recent pharmacy school graduates. METHODS: Six hundred and one graduates were e-mailed a link to an online survey. Subjects were asked to report how frequently they either educate patients on diabetes self-care activities or perform diabetes-related patient care skills and to rate their ability to do so as poor, fair, good, or excellent. RESULTS: Data from 155 (25.8%) respondents were analyzed. The most commonly reported clinical activity was changing medication, followed by interpreting blood glucose patterns, medication management therapy, and interpreting laboratory results. Subjects reported educating patients more on the signs and symptoms of hypoglycemia, blood glucose monitoring, and diet information relative to other topics. The majority of subjects rated their skills as good or excellent. CONCLUSION: Pharmacists reported the most commonly performed diabetes-related clinical skill was changing medication and they most often educate patients about hypoglycemia and blood glucose monitoring. Subjects, who rated themselves poor/fair in these skills, preferred active learning strategies to enhance their ability.

RESUMO

OBJECTIVE: To determine practice outcomes associated with doctor of pharmacy (PharmD) graduates from 2 universities who completed a diabetes-concentration. METHODS: An online survey instrument was sent to 93 PharmD graduates who completed a concentration in diabetes and 94 control graduates to determine their knowledge of and skills in providing diabetes care and how frequently they provided diabetes care services. RESULTS: Ninety-seven graduates (52%) responded. Significantly more graduates with a diabetes concentration rated their ability to instruct patients on insulin administration, blood glucose monitoring, foot care, and insulin dose adjustment as good or excellent compared to a control group of graduates. Graduates with a diabetes concentration also rated their ability to perform blood glucose monitoring and foot examinations higher than graduates without a diabetes concentration (P < 0.05). CONCLUSION: Completing a diabetes concentration increased graduates' knowledge of diabetes and confidence in their ability to provide care but did not appear to alter their practice patterns significantly. Further study is needed to determine whether other barriers to pharmacists providing diabetes care exist in practice settings.

RESUMO

BACKGROUND: Glucagon-like peptide (GLP-1) is a neuroendocrine hormone that increases blood glucose and is a drug target for treatment of type 2 diabetes. Liraglutide, a subcutaneous, once-daily GLP-1 agonist, is approved for the treatment of type 2 diabetes in the United States and Europe. It also has been studied for weight loss. OBJECTIVE: The purpose of this article is to review all of the relevant literature on the chemistry, pharmacology, pharmacokinetics, metabolism, clinical trials, safety, drug interactions, cost, and place in therapy of liraglutide. METHODS: Literature searches of MEDLINE between 1969 and September 2010, International Pharmaceutical Abstracts between 1970 and September 2010, American Diabetes Association Meeting abstracts (2008-2010), and European Association for the Study of Diabetes abstracts (2008-2010) were performed using liraglutide, Victoza, and NN2211 as key terms. RESULTS: Thirteen randomized controlled trials were identified and summarized. Liraglutide has been shown to increase glucose-dependent insulin release by 34% to 118% and reduce postprandial glucagon levels by 20%. Studies showed that liraglutide, as monotherapy and in combination with glimepiride, metformin, and/or rosiglitazone, lowers glycosylated hemoglobin (HbA(1c)) between 0.84% and 1.5%. Transient nausea was reported by 7% to 40% of subjects. Severe hypoglycemia-glucose <55 mg/dL-was observed by 2.5% of subjects in 1 trial. CONCLUSION: Liraglutide safely and effectively reduces HbA(1c) in patients with type 2 diabetes. The most recent American Diabetes Association guidelines recommended a GLP-1 agonist along with metformin as a second-tier therapy for type 2 diabetes. Although the American Association of Clinical Endocrinologists/American College of Endocrinologists' guidelines recommended it for first-line monotherapy in patients with HbA(1c) between 6.5% and 7.5% and with metformin if HbA(1c) is between 7.6% and 8.5%, liraglutide should be considered for patients who cannot tolerate first-line agents or if an additional agent is needed to help reach target HbA(1c) goals.

RESUMO

There is a higher prevalence of low testosterone levels in males with type 2 diabetes compared to those without. Additionally, there is evidence that low testosterone levels may predict the development of type 2 diabetes. Symptoms of hypogonadism include decreased libido, decreased bone mineral density (BMD), and decreased lean muscle mass. The majority of the published cases in men with diabetes were attributed to age-related idiopathic hypogonadotropic hypogonadism. This paper reviews the link between type 2 diabetes and age-related hypogonadism and the treatment options for hypogonadism. Pharmacists who provide care for males with diabetes should be aware of the increased incidence of hypogonadism, know how to screen for it, and be able to recommend appropriate therapy.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: The prevalence of diabetes is increasing worldwide. Over the recent years, new discoveries have led to the development of new pharmacological agents targeting the incretin hormones gastric inhibitory peptide (GIP) and glucagon-like peptide-1 (GLP-1). These agents, called incretin-mimetics, are the newest agents added to the diabetes treatment options. The purpose of this article is to review the relevant literature on the chemistry, pharmacology, pharmacokinetics, metabolism, clinical trials, safety, drug interactions and place in therapy of liraglutide in the treatment of type 2 diabetes. METHODS: An extensive search of the literature was performed with liraglutide and NN2211 as key terms. This article presents a review of the literature related to the chemistry, pharmacology, pharmacokinetics, drug interactions and safety and efficacy of liraglutide. RESULTS AND DISCUSSION: Liraglutide, a subcutaneously administered GLP-1 agonist, displays phamacodynamic and pharmacokinetic properties that allow for once-daily administration. The agent has been shown to be efficacious as monotherapy, as well as in combination with glimperide, metformin and/or rosiglitazone, reducing glycoslyated haemoglobin (A1C) between 0·84% and 1·5%. The primary adverse event reported with liraglutide is transient nausea. WHAT IS NEW AND CONCLUSION: Liraglutide has been well studied in dual and triple combination therapies with sulfonylureas, metformin and rosiglitazone and appears safe and effective. For patients who cannot tolerate first-line agents, metformin, insulin and sulfonylureas, liraglutide is a reasonable treatment option.

RESUMO

OBJECTIVES: To determine the impact of a pregraduation diabetes certificate program on PharmD students' knowledge and skills. METHODS: A comprehensive elective in diabetes was created and implemented in the third-professional year of the PharmD curriculum. A nonrandomized, single-blinded, controlled, 2-year study was conducted to determine the impact of the elective. Written and oral examinations were administered to the participants and students in a control group. RESULTS: The certificate students' (N = 25) and control students' (N = 12) average oral examination grades were 88.5% +/- 13.4% and 89.5% +/- 15.8%, respectively (p = 0.58). The certificate students' average grade on the counseling section of the oral examination was 9% higher than that of the students in the control group (p = 0.01). The certificate students' and control students' grades on the written examination were 80.9 +/- 11.1% and 61.1 +/- 17.4% (p = 0.0062), respectively. CONCLUSIONS: A diabetes certificate program improved students' knowledge of diabetes disease state management and patient education skills compared to students who did not take the elective.

RESUMO

PURPOSE: The goal of treatment of diabetic retinopathy, limitations of laser photocoagulation, endpoints used in clinical studies of diabetic retinopathy treatments, and the mechanism of action, efficacy, and safety of several new and emerging therapies targeting the biochemical pathways that link chronic hyperglycemia with microvascular damage in patients with diabetic retinopathy are discussed. SUMMARY: Improving or preserving vision is the primary goal of treatment for diabetic retinopathy. Limitations of laser photocoagulation include a lack of efficacy in some cases, discomfort from the procedure, the need for repeated treatment, and a risk of retinal damage and scarring. Visual acuity, quality of life, and macular thickness are used as endpoints in clinical studies of diabetic retinopathy treatments. Microvascular damage in patients with chronic hyperglycemia is mediated by interrelated pathways involving aldose reductase, advanced glycation end products, protein kinase C (PKC), and vascular endothelial growth factor (VEGF). Oral aldose reductase inhibitors have been studied with some success only in patients with diabetic peripheral neuropathy. The oral PKC inhibitor midostaurin and oral selective PKC beta inhibitor ruboxistaurin appear promising for improving or maintaining visual acuity, with gastrointestinal complaints the most commonly reported adverse effects. Intra-vitreal injection of corticosteroids or VEGF inhibitors is associated with short-lived improvement in or maintenance of visual acuity, a need for repeated injection, and a risk of local adverse effects. CONCLUSION: A variety of promising new therapies for diabetic retinopathy targeting the biochemical pathways that cause microvascular damage are under investigation. Additional clinical research is needed to determine the role of these new therapies in treating diabetic retinopathy.

RESUMO

OBJECTIVE: To examine the evidence regarding the safety of metformin in heart failure. DATA SOURCES: Searches in MEDLINE and International Pharmaceutical Abstracts were performed (1966-February 2007). Search terms included metformin, heart failure, lactic acidosis, clinical trials, and insulin resistance. STUDY SELECTION AND DATA EXTRACTION: Published studies and case reports that evaluated the causal link between metformin and lactic acidosis in patients with heart failure were selected for review. DATA SYNTHESIS: There were no case reports of patients who had metformin-associated lactic acidosis when heart failure was the only contraindication. Two large retrospective studies showed that metformin does not increase the risk of lactic acidosis in patients with heart failure. However, these retrospective analyses did not account for many important confounding variables. A reduction in mortality rates in metformin users with New York Heart Association Class III and IV heart failure was observed in one small (N = 94) prospective trial. CONCLUSIONS: Results from 3 trials suggest that metformin may be safe to use in heart failure. Large prospective trials are needed to provide conclusive evidence regarding metformin's safety. Until then, use of metformin in heart failure patients should not be recommended routinely. If it is used in patients with heart failure, they should be monitored closely for signs of lactic acidosis.

RESUMO

OBJECTIVE: To evaluate the effectiveness and safety of reduced-dose trivalent inactivated influenza vaccine in adults. DATA SOURCES: A MEDLINE search was conducted (1966-May 2006) using the key search terms inactivated, trivalent, influenza vaccine, dose, and intradermal. DATA SYNTHESIS: Four recent studies evaluated the safety and effectiveness of reduced-dose, inactivated, trivalent influenza vaccine. Reduced doses had immunogenicity similar to that of standard dose vaccination in healthy individuals less than 60 years old. Intramuscular administration caused fewer local adverse effects compared with the other routes of administration. The differences in vaccine administration and dosing used in these studies limit the comparison of their results. CONCLUSIONS: The Centers for Disease Control and Prevention does not recommend vaccinating with reduced-dose influenza vaccine. If reduced-dose vaccination is to be employed during times of vaccine shortage, it should be administered only to healthy adults under the age of 60, and the intramuscular route is preferred.

RESUMO

BACKGROUND: Amylin is a 37-amino acid peptide neurohormone that is cosecreted with insulin from the pancreatic beta cells in response to meals. It lowers serum glucose by decreasing glucagon release, slowing gastric emptying, and decreasing food intake. Pramlintide, a synthetic amylin analogue, is approved by the US Food and Drug Administration for use with mealtime insulin in patients with type 1 diabetes and patients with type 2 diabetes who are using mealtime insulin only or the combination of insulin and metformin and/or a sulfonylurea. OBJECTIVE: This article reviews the available literature on pramlintide with respect to its mechanism of action, pharmacokinetics and pharmacodynamics, clinical efficacy in type 1 and type 2 diabetes, safety and tolerability, dosing, contraindications, and drug interactions. METHODS: MEDLINE (1966-April 2005), Iowa Drug Information Service (1966-April 2005), and International Pharmaceutical Abstracts (1970-April 2005) were searched for clinical trials and therapeutic reviews published in the English language. The search terms were pramlintide and amylin. The bibliographies of identified articles were reviewed for additional references. All relevant studies were included in the review. RESULTS: Six studies, ranging in duration from 4 to 52 weeks, examined the effect of administering pramlintide with premeal insulin in patients with type 1 diabetes. In these trials, pramlintide 120 to 270 microg/d reduced glycosylated hemoglobin (HbA(1c)) by 0.1 % to 0.67%, 1-hour postprandial glucose (PPG) by 4.4 to 7 mmol/L, and 2-hour PPG by 3.6 to 4.8 mmol/L. Five studies, also ranging from 4 to 52 weeks' duration, examined the effect of administering premeal pramlintide in patients with type 2 diabetes. In these trials, pramlintide 90 to 450 microg/d reduced HbA(1c) by 0.3% to 0.62%, 1-hour PPG by 4.8 mmol/L, and 2-hour PPG by 3.4 mmol/L. The principal adverse events reported in clinical trials were nausea and hypoglycemia. The incidence of hypoglycemia in the first 4 weeks of therapy was 2 to 4 times greater with pramlintide compared with placebo; thus, the manufacturer recommends reducing the dose of premeal insulin by 50% when starting pramlintide. Close monitoring of blood glucose levels is recommended when initiating pramlintide therapy. CONCLUSIONS: Use of pramlintide in addition to insulin in patients with type 1 and type 2 diabetes was associated with modest reductions in HbA(1c). The primary adverse effects of pramlintide therapy were nausea and hypoglycemia.

RESUMO

Stroke is the third leading cause of death in the US with recurrent events a high likelihood in those who survive an initial event. The long-term goal of therapy is to prevent the recurrence of stroke and other atherosclerotic events. Aspirin has been the first-line agent for stroke prevention for a long time. As new antiplatelet agents have been introduced, their role in the secondary prevention of stroke remains to be defined. In particular, the role of the combination of aspirin and modified-release dipyridamole (Aggrenox, Boehringer Ingelheim Corp.), the newest product, in the secondary prevention of stroke, remains unknown. The purpose of this manuscript is to review the evidence of these antiplatelet agents in the secondary prevention of stroke and arrive at a conclusion specifically regarding the role of Aggrenox. Clinical studies which examined stroke as a single primary outcome or as one event in a combined primary outcome will be reviewed.

RESUMO

OBJECTIVE: To review the chemistry, pharmacology, efficacy, and safety of trivalent chromium in the treatment of type 2 diabetes and hyperlipidemia. DATA SOURCES: The English literature was searched from 1966 through May 2002 using MEDLINE, International Pharmaceutical Abstracts, and EMBASE. The key words included chromium, glucose, lipids, and diabetes. Pertinent references from review articles and studies were used as additional sources. DATA SYNTHESIS: Trivalent chromium is an essential nutrient and has a key role in lipid and glucose metabolism. Supplementation with chromium does not appear to reduce glucose levels in euglycemia. It may, however, have some efficacy in reducing glucose levels in hyperglycemia. The effects of chromium on lipid levels are variable. Chromium in doses <1000 microg/d appears to be safe for short-term administration. Kidney function and dermatologic changes need to be monitored. CONCLUSIONS: Chromium appears to be a safe supplement and may have a role as adjunctive therapy for treatment of type 2 diabetes. Additional large-scale, long-term, randomized, double-blind studies examining the effect of various doses and forms of chromium are needed.

RESUMO

OBJECTIVE: Treating dyslipidemia in diabetic patients is essential, particularly among minority populations with increased risk of complications. Because little is known about the impact of outpatient diabetes management on lipid outcomes, we examined changes in lipid profiles in urban African-Americans who attended a structured diabetes care program. RESEARCH DESIGN AND METHODS: A retrospective analysis of initial and 1-year follow-up lipid values was conducted among patients selected from a computerized registry of an urban outpatient diabetes clinic. The independent effects of lipid-specific medications, glycemic control, and weight loss on serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were evaluated by analysis of covariance and multiple linear regression. RESULTS: In 345 patients (91% African-American and 95% with type 2 diabetes), HbA(1c) decreased from 9.3% at the initial visit to 8.2% at 1 year (P < 0.001); total and LDL cholesterol and triglyceride levels were significantly lower, and HDL cholesterol was higher. After stratifying based on use of lipid-specific therapy, different outcomes were observed. In 243 patients not taking dyslipidemia medications, average total cholesterol, LDL cholesterol, and triglyceride concentrations at 1 year were similar to initial values, whereas in 102 patients receiving pharmacotherapy, these lipid levels were all lower at 1 year relative to baseline (P < 0.001). Mean HDL cholesterol increased regardless of lipid treatment status (P < 0.001). After adjusting for other variables, changes in LDL cholesterol concentration were associated only with use of lipid-specific agents (P = 0.003), whereas improved HbA(1c) and weight loss had no independent effect. Lipid therapy, improved glycemic control, and weight loss were not independently related to changes in HDL cholesterol and therefore could not account for the positive changes observed. Use of lipid-directed medications, improvement in glycemic control, and weight loss all resulted in significant declines in triglyceride levels but only improved HbA(1c) and weight loss had an independent effect. CONCLUSIONS: Among urban African-Americans, diabetes management led to favorable changes in HDL cholesterol and triglyceride levels, but improved glycemic control and weight loss had no independent effect on LDL cholesterol concentration. Initiation of pharmacologic therapy to treat high LDL cholesterol levels should be considered early in the course of diabetes management to reach recommended targets and reduce the risk of cardiovascular complications in this patient population.
