El reto del envejecimiento y la complejidad farmacoterapéutica en el paciente VIH+

Objective: To describe the current knowledge and management of aging and pharmacotherapeutic complexity in HIV + patients. Method: A review of literature was carried out, including articles, originals or reviews, published in English or Spanish, from 2007 to 2017, which analysed the aging and pharmacotherapeutic complexity in HIV + patients. The terms «Polypharmacy»/«Polifarmacia», «Aging»/«Envejecimiento», «Frailty»/«Fragilidad», «Complejidad Farmacotera péutica»/«Medication Regimen Complexity» and «HIV»/«VIH» were combined. The review was carried out independently by two authors. The degree of agreement, according to the Kappa index, was analysed. Results: A total of 208 references were analysed, including, finally, only 68. An aging of the population and an increase in associated comorbidities have been identified, especially over 50 years-old. Immunological changes similar to those that are generated in a non-infected elderly population have been described. These conditions influencing the prescription of antiretroviral treatment, according to studies identified. In parallel, polypharmacy is increasingly present, being defined exclusively by the concomitant use of five drugs. Pharmacotherapeutic complexity, through the Medication Regimen Complexity Index, has begun to analyse and relate to health outcomes. There has been a need to know and apply concepts already known in non-HIV-aged population, such as deprescription, potentially inappropriate medication, cholinergic risk, although few results are available. Conclusions: There is a growing interest to know about the relationship between HIV and aging. Pharmacotherapeutic complexity is beginning to be used as a pharmacotherapeutic follow-up criterion due to its influence on health outcomes. It is necessary to manage and incorporate new concepts that help pharmacotherapeutic optimization in this population

Efecto sobre la adherencia a medicaciones concomitantes tras el inicio del tratamiento con antivíricos de acción directa para el virus de la hepatitis C

[EN]: [Introduction]: Many patients with hepatitis C virus (HCV) have associated comorbidities that require complex treatments. We sought to determine the impact of treatment with direct-acting antiviral agents (DAAs) for HCV on adherence to prescribed concomitant medications for associated comorbidities and to identify predictors of non-adherence to comedications. [Patients and methods]: HCV-infected patients treated with DAAs in a Spanish hospital between January 2015 and December 2016 and followed-up by the pharmacy unit were included in the study. Adherence to concomitant comedication prescribed before and during HCV therapy with DAAs was compared to adherence during the same number of weeks before DAA initiation. Demographic, clinical and pharmacotherapy variables were analyzed to determine factors associated with non-adherence. A multivariate regression model was created for prediction of non-adherence to concomitant medication. [Results]: Data from 214 patients using prescribed concomitant therapies were analyzed. Significant reduction on adherence to comedications was observed after initiation of DAA treatment compared with a similar period before therapy initiation (29.9% vs. 36.9%, p = 0.032). The univariate analysis showed that polypharmacy and presence of vascular disease were associated negatively with adherence to concomitant medications (87.8%, p = 0.006 and 84.7%, p < 0.001, respectively). Multivariate analysis indicated that HIV/HBV coinfection was associated with adherence (OR 0.19; 95% CI 0.09–0.39), while polypharmacy was a predictor for non-adherence (OR 4.54; 95% CI 1.48–13.92). [Discussion]: Adherence to concomitant medications decreases in HCV-infected patients when DAA therapy is initiated. Polypharmacy is a predictor for non-adherence, while HIV/HBV coinfection reduce non-adherence rates. Polymedicated patients on DAAs might benefit from close follow-up and educational programmes to improve their adherence.[ES]: [Introducción]: Muchos pacientes con virus de la hepatitis C (VHC) presentan comorbilidades que requieren tratamientos complejos. Queremos determinar el impacto del tratamiento con antivirales de acción directa (AAD) para el VHC en la adherencia a medicaciones concomitantes e identificar factores predictivos de no adherencia a comedicaciones. [Pacientes y métodos]: Pacientes tratados con AAD entre 2015 y 2016 se incluyeron en el estudio y se comparó su adherencia a medicaciones concomitantes antes y durante la terapia con AAD en un periodo de tiempo similar. Múltiples variables fueron analizadas para identificar factores asociados a la no-adherencia. Se creó un modelo de regresión multivariable para predecir la no adherencia a medicaciones concomitantes. [Resultados]: Se analizaron datos de 214 pacientes en tratamientos concomitantes. Tras iniciar la terapia con AAD, la adherencia a las comedicaciones disminuyó respecto a la adherencia en ausencia de AAD (29,9% respecto al 36,9%; p = 0,032). El análisis univariante demostró que la polifarmacia y la enfermedad vascular estaban asociadas negativamente con la adherencia a las medicaciones concomitantes (87,8%, p = 0,006 y 84,7%, p < 0,001, respectivamente). El análisis multivariante indicó que la coinfección con VIH/VHB estaba asociada con la adherencia (OR: 0,19; IC 95%: 0,09-0,39), mientras que la polifarmacia era un predictor de no adherencia (OR: 4,54; IC 95%: 1,48-13,92). [Discusión]: El inicio del tratamiento con AAD disminuye la adherencia a la comedicación en pacientes con VHC. La polifarmacia es predictor de no adherencia mientras que la coinfección con VIH/VHB la reduce. Aquellos pacientes polimedicados y en tratamiento con AAD podrían beneficiarse de un seguimiento estrecho para aumentar su adherencia.JAP has received a research extension grant from the Pro-grama de Intensificación de la Actividad de Investigacióndel Servicio Nacional de Salud Carlos III (I3SNS), fromSpain and financial support from ISCIII-Subdirección Gen-eral de Evaluación and the European Regional Development Fund (ERDF) (www.red.es/redes/inicio) (RD16/0025/0040and RD12/0017/0012).Medical Writing support was provided by Vanessa Marfil (Medical Science Consulting, Valencia).

High rate of major drug–drug interactions of lopinavir–ritonavir for COVID-19 treatment

The impact of drug–drug interactions (DDI) between ritonavir-boosted lopinavir (LPV-r) to treat patients with coronavirus disease 2019 (COVID-19) and commonly used drugs in clinical practice is not well-known. Thus, we evaluated the rate and severity of DDI between LPV-r for COVID-19 treatment and concomitant medications. This was a cross-sectional study including all individuals diagnosed of SARS-CoV-2 infection treated with LPV-r and attended at a single center in Southern Spain (March 1st to April 30th, 2020). The frequency [95% confidence interval (95% CI)] of potential and major DDI were calculated. Overall, 469 patients were diagnosed of COVID-19, 125 (27%) of them were prescribed LPV-r. LPV-r had potential DDI with concomitant medications in 97 (78%, 95% CI 69–85%) patients, and in 33 (26%, 95% CI 19–35%) individuals showed major DDI. Twelve (36%) patients with major DDI and 14 (15%) individuals without major DDI died (p = 0.010). After adjustment, only the Charlson index was independently associated with death [adjusted OR (95% CI) for Charlson index ≥ 5: 85 (10–731), p < 0.001]. LPV-r was discontinued due to side effects in 31 (25%) patients. Management by the Infectious Diseases Unit was associated with a lower likelihood of major DDI [adjusted odds ratio (95% CI): 0.14 (0.04–0.53), p = 0.003). In conclusion, a high frequency of DDI between LPV-r for treating COVID-19 and concomitant medications was found, including major DDI. Patients with major DDI showed worse outcomes, but this association was explained by the older age and comorbidities. Patients managed by the Infectious Diseases Unit had lower risk of major DDI.This study has not been funded.

Drug–drug interactions between treatment specific pharmacotherapy and concomitant medication in patients with COVID-19 in the first wave in Spain

Abstract Primary aim was to assess prevalence and severity of potential and real drug–drug interactions (DDIs) among therapies for COVID-19 and concomitant medications in hospitalized patients with confirmed SARS-CoV-2 infection. The secondary aim was to analyze factors associated with rDDIs. An observational single center cohort study conducted at a tertiary hospital in Spain from March 1st to April 30th. rDDIs refer to interaction with concomitant drugs prescribed during hospital stay whereas potential DDIs (pDDIs) refer to those with domiciliary medication. DDIs checked with The University of Liverpool resource. Concomitant medications were categorized according to the Anatomical Therapeutic Chemical classification system. Binomial logistic regression was carried out to identify factors associated with rDDIs. A total of 174 patients were analyzed. DDIs were detected in 152 patients (87.4%) with a total of 417 rDDIs between COVID19-related drugs and involved hospital concomitant medication (60 different drugs) while pDDIs were detected in 105 patients (72.9%) with a total of 553 pDDIs. From all 417 rDDIs, 43.2% (n = 180) were associated with lopinavir/ritonavir and 52.9% (n = 221) with hydroxychloroquine, both of them the most prescribed (106 and 165 patients, respectively). The main mechanism of interaction observed was QTc prolongation. Clinically relevant rDDIs were identified among 81.1% (n = 338) (‘potential interactions’) and 14.6% (n = 61) (contraindicated) of the patients. Charlson index (OR 1.34, 95% IC 1.02–1.76) and number of drugs prescribed during admission (OR 1.42, 95% IC 1.12–1.81) were independently associated with rDDIs. Prevalence of patients with real and pDDIs was high, especially those clinically relevant. Both comorbidities and polypharmacy were found as risk factors independently associated with DDIs development

Similar incidence of coronavirus disease 2019 (COVID-19) in patients with rheumatic diseases with and without hydroxychloroquine therapy.

Hydroxychloroquine is not efficacious as post-exposure prophylaxis against coronavirus disease 2019 (COVID-19). It is not known whether as pre-exposure prophylaxis it may prevent COVID-19. To compare the incidence of COVID-19 in Spanish patients with autoimmune rheumatic diseases treated with and without hydroxychloroquine. Retrospective electronic record review, from February 27th to June 21st, 2020, of patients with autoimmune inflammatory diseases followed at two academic tertiary care hospitals in Seville, Spain. The cumulative incidence of confirmed COVID-19, by PCR or serology, was compared between patients with and without hydroxychloroquine as part of their treatment of autoimmune inflammatory diseases. Among 722 included patients, 290 (40%) were receiving hydroxychloroquine. During the seventeen-week study period, 10 (3.4% [95% CI: 1.7%-6.7%] cases of COVID-19 were registered among patients with hydroxychloroquine and 13 (3.0% [1.6%-5.1%]) (p = 0.565) in those without hydroxychloroquine. COVID-19 was diagnosed by PCR in four (1.4%, 95% CI 0.38%-3.5%) subject with hydroxychloroquine and six (1.4%, 95% CI 0.5%-3.0%) without hydroxychloroquine (p = 0.697). Three patients on hydroxychloroquine and four patients without hydroxychloroquine were admitted to the hospital, none of them required to be transferred to the intensive care unit and no patient died during the episode. The incidence and severity of COVID-19 among patients with autoimmune rheumatic diseases with and without hydroxychloroquine was not significantly different

VIH en España 2017: políticas para una nueva gestión de la cronicidad más allá del control virológico

ABSTRACT The analysis of the available databases related to HIV/AIDS confirms a paradigm shift in the patient’s life expectancy: now HIV has become a chronic disease, so patients are aging. However, this advance is accompanied by a negative counterpart: due to the increase in the number of years of life gained, there is a prevalence of comorbidities greater than the general population and at an earlier age. Reducing the risk associated with all the comorbidities that the ageing patient with HIV/AIDS may develop, must now be a health objective; it must be added to the traditional objectives that until now were part of the strategy to reduce the impact of the HIV infection. In the specific case of women, it is also necessary to train peri and postmenopausal women to increase their skills and motivation to care for their health; It is also very important to examine the role that hormone replacement therapy can play in reducing their symptoms.RESUMEN El análisis de las bases de datos disponibles relacionadas con VIH/SIDA confirma un cambio de paradigma en la esperanza de vida del paciente: ahora el VIH se ha convertido en una enfermedad crónica, con la que los pacientes están envejeciendo. No obstante, este avance se acompaña de una contraparte negativa: debido al incremento en el número de años de vida ganados, se da una prevalencia de comorbilidades mayor a la de la población general y a una edad más temprana. Reducir el riesgo asociado a todas las comorbilidades que puede desarrollar el paciente con VIH/SIDA mientras envejece debe ser hoy en día un objetivo de salud, que se suma a los objetivos tradicionales que hasta ahora formaban parte de la estrategia para reducir el impacto de la infección por el VIH. En el caso específico de la mujer, además es necesario formar a las mujeres peri y postmenopáusicas para incrementar sus habilidades y su motivación para el cuidado de su salud; también es muy importante que se examine el rol que puede tener la terapia de reemplazo hormonal en la reducción de sus síntomas
