ObjectivesTo compare outcomes with single tablet regimens (STR) versus multi-tablet regimens (MTR) for human immunodeficiency virus (HIV) treatment using published data.DesignSystematic review and random-effects meta-analysis of literature on approved and investigational HIV regimens.MethodsThe research followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Single or un-blinded studies reporting a direct comparison between STR and MTR were eligible for the meta-analysis. Double-blinded studies were excluded due to lack of difference in pill burden between cohorts. The key outcomes of interest included: adherence rates/proportion meeting target, efficacy, safety/tolerability, non-clinical and economic outcomes.ResultsAfter screening 63 full-text articles and posters, 14 studies were eligible for the meta-analysis. The analysis showed that patients taking STR had improved outcomes over those taking MTR. Patients were significantly more adherent regardless of daily dosing frequency (odds ratio [OR]: 1.96, p < 0.001) and were more likely to achieve virological suppression (relative risk [RR]: 1.05, p = 0.002). There was a trend toward a lower discontinuation risk in the STR cohort, together with reported higher therapy satisfaction, better symptom control, improved health status, reduced healthcare resource utilization and demonstrated cost-effectiveness compared to MTR. There were no differences in CD4 cell count increase (at 48 weeks) or safety outcomes.ConclusionsThe findings of this study confirm previously reported preliminary findings of the advantages of STR over MTR for HIV treatment in adherence, therapy continuation, viral suppression, tolerability, quality of life improvement, cost-effectiveness and healthcare resource utilization.Electronic supplementary materialThe online version of this article (10.1186/s12981-018-0204-0) contains supplementary material, which is available to authorized users.
Selective serotonin reuptake inhibitors (SSRIs) are among the most commonly prescribed medications in the United States. Although SSRIs are highly tolerable relative to other antidepressants, they are associated with a number of adverse effects, including increased gastrointestinal tract bleeding and intracranial bleeding. Mechanisms include increased gastric acid secretion and inhibition of serotonin entrance into platelets. Patients with other bleeding risk factors, such as warfarin, clopidogrel, or aspirin use, may be at heightened risk of these adverse effects. The purpose of this article is to review the incidence of gastrointestinal tract bleeding or intracranial bleeding associated with concomitant SSRI use, the proposed mechanisms of, and the potential pharmacokinetic/pharmacodynamic interactions with anticoagulants and antiplatelets. Given the prevalence of SSRI use in the ambulatory setting, osteopathic physicians should be aware of potential drug-drug interactions and the clinical implications of SSRI-associated bleeding risk.
Introduction: Anticoagulants are among the most frequently prescribed medications in the United States. Racial and ethnic disparities in incidence and outcomes of thrombotic disorders are well-documented, but differences in response to anticoagulation are incompletely understood. Objective: The objective of this review is to describe the impact of race and ethnicity on surrogate and clinical end points related to anticoagulation and discuss racial or ethnic considerations for prescribing anticoagulants. Methods: A PubMed and MEDLINE search of clinical trials published between 1950 and May 2018 was conducted using search terms related to anticoagulation, specific anticoagulant drugs, race, and ethnicity. References of identified studies were also reviewed. English-language human studies on safety or efficacy of anticoagulants reporting data for different races or ethnicities were eligible for inclusion. Results: Seventeen relevant studies were identified. The majority of major trials reviewed for inclusion either did not include representative populations or did not report on the racial breakdown of participants. Racial differences in pharmacokinetics, dosing requirements, drug response, and/or safety end points were identified for unfractionated heparin, enoxaparin, argatroban, warfarin, rivaroxaban, and edoxaban. Conclusions: Race appears to influence drug concentrations, dosing, or safety for some but not all direct oral anticoagulants. This information should be considered when selecting anticoagulant therapy for nonwhite individuals.
Background and Aims Patients with familial hypercholesterolemia (FH) may be at increased risk of statin-associated muscle symptoms since they require long-term treatment with high-intensity statin therapy. We sought to determine 1) whether other predisposing factors, including the well-known genetic variant associated with statin-associated muscle symptoms - solute carrier organic anion transporter family, member 1B1 (SLCO1B1) rs4149056 – also increase the risk of statin-associated muscle symptoms in FH patients, and 2) the natural history and management for FH patients with statin-associated muscle symptoms. Methods We queried electronic records (2004–2014) of 278 genetically screened FH patients (113 men, 165 women; mean [SD] pretreatment LDL-C 259 [72] mg/dL) recruited from lipid clinics in the Dallas, TX area from 2004 to 2014. Statin-associated muscle symptoms were defined as muscle symptoms arising while taking a statin and interrupting therapy. Results The risk of muscle symptoms was associated with age (OR 1.6, [95% CI 1.2, 2.2]), BMI in non-African-Americans (0.90 [0.83, 0.97]), and hypertension (0.4, [0.2, 0.9]). Simvastatin most commonly employed and most associated with muscle symptoms. Among FH patients with muscle symptoms, 41% (n = 40) reestablished statin therapy (“eventually tolerant”) and 29% (n = 28) never reestablished statin therapy (“never tolerant”). Rosuvastatin (43%) and pravastatin (30%) were the most common eventually-tolerated statins, and “eventually tolerant” patients achieved lower treated LDL-C levels (“eventually tolerant” 127 vs “never tolerant” 192 mg/dL, p < 0.001). “Never tolerant” patients also developed muscle symptoms on non-statins (16% vs. 50%, p = 0.003). SLCO1B1 rs4149056 genotyping revealed 224 wild-type patients (TT) and 49 heterozygotes (TC). SLCO1B1 genotype was not associated with the risk of statin-associated muscle symptoms (OR 1.40, [95% CI 0.74–2.64]). Conclusion Age, not SLCO1B1 rs4149056 genotype, was the strongest risk factor for statin-associated muscle symptoms in FH patients. After developing muscle symptoms, many patients reestablished statin therapy and achieved significant LDL-C reductions. Overall, 10% of all FH patients had statin-associated muscle symptoms and never re-established statin therapy. Such patients developed muscle symptoms even on non-statin lipid lowering drugs and continued to have elevations in LDL-C. Further insight is needed into the relationship of FH and statin-associated muscle symptoms so all FH patients can be adequately treated.
