Analysis to retreatment with monoclonal antibodies in chronic/episodic migraine: Real world data. / [Artículo traducido] Análisis del retratamiento con anticuerpos monoclonales en la migraña crónica/episódica: datos en vida real.

OBJECTIVE: To analyze the response to retreatment in patients with chronic/episodic migraine who discontinued therapy with erenumab/fremanezumab after one year of treatment. METHODS: Observational, retrospective, single-center, multidisciplinary study in patients with chronic/episodic migraine who received therapy with erenumab/fremanezumab for at least one year and discontinued it after achieving an adequate response (optimization). The evaluation of the response after retreatment included the following variables: migraine days per month, MIDAS and HIT-6 scales at the beginning of retreatment and 3 months later. The response was evaluated in different subgroups (episodic/chronic, erenumab/fremanezumab and time until retreatment). RESULTS: 48 patients were included. 70.8% (n=34) required retreatment with mAb, with a median of 3.9 (2.9-6.4) months until reintroduction. Clinical response after retreatment was achieved in 67.6% (n=23) of patients. No statistically significant differences were found in the analyzed subgroups. CONCLUSION: Interruption of treatment with erenumab/fremanezumab for chronic/episodic migraine produces a clinical worsening of the disease requiring retreatment in most cases, approximately after 4 months. Two out of three patients respond positively after restarting monoclonal therapy. This response does not appear to be related to the type of migraine, the specific monoclonal antibody prescribed, or the time to retreatment.

Potentially inappropriate medications according to Marc, STOPP and PRISCUS criteria in a cohort of elderly HIV+ patients.

Introduction: The objective is to determine the prevalence of potentially inappropriate drugs according to the Marc, STOPP, and PRISCUS lists in elderly HIV patients. Patients and methods: It was an observational, retrospective, and multicenter study. People living with HIV 65 years or older who underwent chronic concomitant treatment were included. Descriptive and multivariate analyzes were performed to study the association between polypharmacy and potentially inappropriate medication compliance. Results: A total of 55 patients were included, 81.8% men and a median age of 69 years (IQR: 67-73). The median number of comorbidities was 3 (IQR: 2-5) and the most frequent pattern of multimorbidity was cardiometabolic (62.9%). The predominant antiretroviral treatment was triple therapy (65.5%). Polypharmacy was present in 70.9% of the patients and 25.5% had major polypharmacy. The most frequent polypharmacy pattern was cardiovascular (69.2%). The percentage of potentially inappropriate medications according to the Marc, STOPP and PRISCUS lists was 65.5%, 30.9% and 14.5%, respectively (p<0.001). Adjusted for age and sex, polypharmacy was not independently associated with potentially inappropriate medication compliance in any of the lists. Conclusion: Polypharmacy and potentially inappropriate medications have a high prevalence. There is great variability in the percentage according to the list applied. Age, sex, and presence of polypharmacy are not predisposing factors to the presence of potentially inappropriate medications. (AU)

Introducción: El objetivo de este estudio es determinar la prevalencia de medicamentos potencialmente inapropiados según los listados Marc, STOPP y Priscus en pacientes VIH+ de edad avanzada. Pacientes y métodos: Estudio observacional, transversal y multicéntrico. Se incluyeron aquellos pacientes VIH+ mayores de 65 años en tratamiento antirretroviral y tratamiento concomitante crónico. Para conocer la asociación entre polifarmacia y presencia de medicación potencialmente inapropiada se llevaron a cabo análisis descriptivos y multivariante.Resultados: Se incluyeron 55 pacientes (81.8% hombres); mediana de edad 69 años (RIQ 67-73). Todos presentaban alguna comorbilidad (mediana 3, RIQ 2-5). El patrón de multimorbilidad más frecuente fue cardio-metabólico (62.9%). La triple terapia fue el esquema de tratamiento antiretroviral predominante (65.5%) y el patrón de polifarmacia más frecuente fue el cardiovascular (69.2%). Se identificó presencia de polifarmacia en un 70,9% y un 25,5% polifarmacia mayor. El cumplimiento de algún criterio según el listado Marc, STOPP y PRISCUS observó en 65,5%, 30,9% y 14,5% de los pacientes (p<0.001). Según análisis multivariante se observa que la edad, sexo o presencia de polifarmacia no son factores determinantes de presencia de medicamentos inapropiados en los listados. Conclusión. La prevalencia de medicación potencialmente inapropiada según los listados utilizados fue alta, existiendo una gran variabilidad en la identificación entre las diferentes herramientas. Edad, sexo y polifarmacia no son factores predictivosde presencia de medicamentos potencialmente inapropiados. (AU)

Prevalence of compliance with PIMDINAC criteria among elderly people living with HIV and in non-infected outpatients with other chronic diseases.

BACKGROUND: There is a high prevalence of multimorbidity and polypharmacy among older people, especially in people living with HIV (PLWH) with an increased life expectancy due to effective antiretroviral therapy (ART). Consequently, there is a higher risk of potentially inappropriate medications (PIM), potential drug-drug interactions (DI), and problems of non-adherence to treatment (NAC) in older PLWH. PIMDINAC criteria (potentially inappropriate medications (PIM), drug-drug interactions (DI), and non-adherence to treatment (NAC)) purport to jointly analyse these problems. The purpose of the study was to compare the prevalence of PIMDINAC criteria among elderly PLWH and non-infected patients with chronic diseases, and to determine whether HIV infection constitutes a predictor of the presence of PIMDINAC criteria, totally or partially. METHODS: A cross sectional study was conducted between February and June 2020. HIV positive patients aged ≥65 years were compared with a group of patients with chronic conditions attending the outpatient hospital pharmacy service. RESULTS: The study involved 140 patients: 47 HIV positive and 93 HIV negative, and mean age was 69 versus 73 years, respectively (p=0.062). The prevalence of total PIMDINAC criteria was similar between the groups (12.5 vs 10.8%, p=0.505). In relation to inappropriate medication, no differences were observed between groups (48.9 vs 55.9%, p=0434). Drug-drug interactions were higher in patients with chronic conditions (52.7 vs 25.5%, p=0.002) compared with non-adherence, which was higher in people with HIV (22.6 vs 65.6%, p<0.001). No differences in polypharmacy (≥6 and 11 drugs) rates were observed. CONCLUSIONS: PIMDINAC criteria were highly prevalent in older PLWH, similar to non-infected patients. HIV infection in older people was associated with a lower risk of drug-drug interactions. However, non-adherence was a risk factor compared with age matched controls. Deprescribing strategies, including a capability-motivation-opportunity pharmaceutical care model based intervention should be implemented in clinical routines.
