          Abstract

          Resumen Introducción: De acuerdo con la Organización Mundial de la Salud el Virus de la Inmunodeficiencia Humana (VIH) continúa siendo uno de los mayores problemas para la salud pública mundial. A día de hoy, la importancia de la adherencia al tratamiento continúa siendo el centro de atención de todos los profesionales sanitarios. La falta de adherencia supone un gran problema económico y sanitario. Método: Este estudio se centra en el servicio de atención farmacéutica (AF) realizado a los pacientes VIH en tratamiento con el comprimido coformulado dolutegravir/lamivudina (DTG/3TC) desde su comercialización en julio de 2019 hasta mayo 2021.Variables estudiadas: sexo, edad, adherencia, carga viral, recuento de linfocitos CD4, terapia antirretroviral (TAR) previa en paciente no naive, tratamientos concomitantes, interacciones, en pacientes no naive el motivo que ha conducido al cambio de TAR y los efectos adversos (EA) desarrollados. Fuente de datos: programa informático dispensación pacientes externos e historia clínica electrónica. Resultados: En el servicio de AF en la primera entrevista con el farmacéutico se tratan cinco aspectos: adherencia, EA, tratamientos y/o productos de herboristería concomitantes, interacciones y motivo de cambio de TAR. 62 pacientes iniciaron tratamiento con DTG/3TC: 24,1% (15/62) naive y 75,8% (47/62) no naive. El 100% de los pacientes naive presentaron una alta adherencia, solamente el 6,4% de los pacientes pretratados fueron identificados como no adherentes. Se encontró una contraindicación: hipérico. Conclusiones: Los pacientes presentan una alta adherencia, el tratamiento es efectivo y seguro. Se realiza el servicio de AF de forma eficaz. Conocemos la adherencia de nuestros pacientes y realizamos un estrecho seguimiento farmacoterapéutico.

          Abstract Introduction: According to the World Health Organization, Human Immunodeficiency Virus (HIV) continues being one of the world's major public health problems. Currently, the importance of adherence to treatment continues being the focus of attention of health professionals. Lack of adherence is a major economic and health problem. Method: This study focuses on the pharmaceutical care service performed on all HIV patients (naive and non-naive) on treatment with the coformulated tablet dolutegravir/lamivudine (DTG/3TC) from its commercialization in July 2019 until May 2021. Variables studied: sex, age, adherence, viral load, CD4 lymphocyte count, previous antiretroviral therapy (ART) in non-naïve patients, concomitant treatments, interactions, the reason that led to the change of ART in non-naïve patient and the adverse effects developed. Results: In the first interview with the pharmacist in the pharmaceutical care service, five fundamental aspects are discussed: adherence, adverse effects, concomitant treatments and/or herbal products, interactions and reason for changing antiretroviral drugs in non-naive patients. 62 patients started treatment with DTG/3TC: 24.1% (15/62) naive and 75.8% (47/62) no naive. 100% of naive patients were highly adherent, only 6.4% of pre-treated patients were identified as non-adherent. Only one contraindication was found: hypericum. Conclusions: Patients are highly adherent, the treatment is effective and safe. The pharmaceutical care service is carried out efficiently. We are aware of our patients' adherence and carry out close pharmacotherapeutic monitoring.

          Meta-Analysis of Studies Comparing Single and Multi-Tablet Fixed Dose Combination HIV Treatment Regimens

          Abstract Availability of a single source review of once-daily fixed-dose single tablet regimen (STR) and multiple tablet fixed-dose regimen (MTR) would optimally inform healthcare providers and policy makers involved in the management of population with human immunodeficiency virus (HIV). We conducted a meta-analysis of published literature to compare patient adherence, clinical, and cost outcomes of STR to MTR. Published literature in English between 2005 and 2014 was searched using Embase, PubMed (Medline in-process), and ClinicalTrials.Gov databases. Two-level screening was undertaken by 2 independent researchers to finalize articles for evidence synthesis. Adherence, efficacy, safety, tolerability, healthcare resource use (HRU), and costs were assessed comparing STR to MTR. A random-effects meta-analysis was performed and heterogeneity examined using meta-regression. Thirty-five articles were identified for qualitative evidence synthesis, of which 9 had quantifiable data for meta-analysis (4 randomized controlled trials and 5 observational studies). Patients on STR were significantly more adherent when compared to patients on MTR of any frequency (odds ratio [OR]: 2.37 [95% CI: 1.68, 3.35], P < 0.001; 4 studies), twice-daily MTR (OR: 2.53 [95% CI: 1.13, 5.66], P = 0.02; 2 studies), and once-daily MTR (OR: 1.81 [95% CI: 1.15, 2.84], P = 0.01; 2 studies). The relative risk (RR) for viral load suppression at 48 weeks was higher (RR: 1.09 [95% CI: 1.04, 1.15], P = .0003; 3 studies) while RR of grade 3 to 4 laboratory abnormalities was lower among patients on STR (RR: 0.68 [95% CI: 0.49, 0.94], P = 0.02; 2 studies). Changes in CD4 count at 48 weeks, any severe adverse events (SAEs), grade 3 to 4 AEs, mortality, and tolerability were found comparable between STR and MTR. Several studies reported significant reduction in HRU and costs among STR group versus MTR. Study depicted comparable tolerability, safety (All-SAE and Grade 3–4 AE), and mortality and fewer Grade 3 to 4 lab abnormalities and better viral load suppression and adherence among patients on FDC-containing STR versus MTR; literature depicted favorable HRU and costs for STRs. These findings may help decision makers especially in resource-poor settings to plan for optimal HIV disease management when the choice of both STRs and MTRs are available.

            Antiretroviral regimen complexity, self-reported adherence, and HIV patients' understanding of their regimens: survey of women in the her study.

            Research regarding treatment adherence in chronic diseases, such as hypertension, suggests that increasing complexity in the medication regimen is associated with decreasing patient adherence. However, less is known about the relationship between regimen complexity and adherence in the treatment of HIV/AIDS. To examine the relationship between antiretroviral (ART) regimen complexity and patient understanding of correct regimen dosing to adherence (missing doses in the past 1 and 3 days). Cross-sectional survey of a cohort of women living with HIV/AIDS and enrolled in the HER (HIV Epidemiologic Research) Study. Seventy-five percent of patients correctly understood the dosing frequency of their ART medications, 80% understood the food-dosing restrictions, whereas only 63% understood both. The percentage of patients with a correct understanding of dosing decreased with increasing regimen complexity (increased dosing frequency and food-dosing restrictions). Patients were more likely to have missed doses in the previous 3 days if they were taking ART medications three or more times per day or had to take one or more antiretrovirals on an empty stomach. A multivariate logistic regression model demonstrated that patients with less complex regimens (twice daily or less in frequency, no food-dosing restrictions) who correctly understood the dosing and food restrictions of their ART regimen were less likely to have skipped doses in the past three days (odds ratio [OR], 0.4; 95% confidence interval [CI], 0.2-0.7) than those with more complex regimens. Younger age and higher CD4 count were also associated with a reduced likelihood of skipping doses. No association was found between adherence and race/ethnicity, current or past injection drug use, or education. Self-reported adherence is better among patients with less complex ART regimens. This is in part because patients' understanding of regimen dosing decreases as regimen complexity increases. Therefore, simplifying antiretroviral regimens may have an important role in improving patients' adherence.
