Abstract
in English, Spanish

Objectives: To determine the prevalence of potential interactions in COVID19 patients receiving lopinavir/ritonavir (LPV/r). The secondary objective was to develop recommendations and identify the risk factors associated with presenting potential interactions with LPV/r.

Subjects and methods: Cross-sectional and multicenter study with the participation of 2 hospitals. COVID 19 patients over 18 years of age, admitted to hospital and under treatment with LPV/r were included. A screening of potential interactions related to LPV/r and home and hospital medication was carried out. Lexicomp® (Uptodate), HIV-drug interactions and COVID-drug interactions were used as the query database.

Results: 361 patients with a mean age of 62.77 ± 14.64 years were included, where 59.6% (n = 215) were men. 62.3% (n = 225) had 1 or more potential interactions and 26, 87% (n = 97) 2 or more. The independent variables associated with presenting ≥1 potential interactions were age (>65) (OR 1.95; 95% CI 1.06-3.59, P = .033), ICU admission (OR 9.22; CI 95% 1.98-42.93; P = .005), previous respiratory pathology (OR 2.90; 95% CI 1.15-7.36; P = .024), psychiatric (OR 4.14; 95 CI% 1.36-12.61; P = .013), dyslipidemia (OR 3.21; 95% CI 1.63-6.35; P = .001) and the number of drugs prescribed (OR 4.33; 95% CI 2.40-7.81; P = .000).

Conclusion: The prevalence of potential interactions in COVD 19 patient undergoing treatment with LPV/r is high, with age (>65), ICU admission, previous respiratory and psychiatric pathology, dyslipidemia and the number of prescribed drugs acting as risk factors.

Objetivos: Determinar la prevalencia de interacciones potenciales en pacientes COVID19 en tratamiento con lopinavir/ritonavir (LPV/r). El objetivo secundario fue elaborar recomendaciones e identificar los factores de riesgo asociados a presentar interacciones potenciales con LPV/r.

Sujetos y métodos: Estudio transversal y multicéntrico con la participación 2 hospitales. Se incluyeron pacientes COVID 19 mayores de 18 años, con ingreso hospitalario y en tratamiento con LPV/r. Se realizó un cribado de las interacciones potenciales relacionadas con LPV/r y la medicación domiciliaria y hospitalaria. Se utilizó como base de datos de consulta Lexicomp® (Uptodate), HIV-drug interacctions y COVID-drug interacctions.

Resultados: Se incluyeron 361 pacientes con una media de edad de 62,77 ± 14,64 años, donde el 59,6% (n = 215) fueron hombres. El 62,3% (n = 225) tuvieron 1 o más interacciones potenciales y el 26, 87% (n = 97) 2 o más. Las variables independientes asociadas a presentar ≥ 1 interacciones potenciales fueron la edad (> 65) (OR 1,95; IC 95% 1,06–3,59; P = ,033), el ingreso en UCI (OR 9,22; IC 95% 1,98–42,93; P = ,005), la patología previa respiratoria (OR 2,90; IC 95% 1,15–7,36; P = ,024), psiquiátrica (OR 4,14; IC 95% 1,36–12,61; P = ,013), la dislipemia (OR 3,21; IC 95% 1.63–6,35; P = ,001) y el número de fármacos prescrito (OR 4,33; IC 95% 2,40–7,81; P = ,000).

Conclusión: La prevalencia de interacciones potenciales en paciente COVD 19 en tratamiento con LPV/r es elevada, comportándose como factores de riesgo asociados la edad (>65), el ingreso en UCI, la patología previa respiratoria, psiquiátrica y la dislipemia y el número de fármacos prescritos.
