RESUMEN

Introducción: La adherencia al tratamiento farmacológico favorece la supresión viral y reduce la resistencia a la terapia antirretroviral de gran actividad a largo plazo. Objetivo: Determinar la relación entre los aspectos farmacológicos y la adherencia al tratamiento antirretroviral de una IPS colombiana. Metodología: Estudio analítico transversal en pacientes con diagnóstico de VIH en tratamiento antirretroviral entre los años 2012 a 2020. Se utilizó un modelo de regresión logística binaria múltiple con fines explicativos. Resultados: Se analizaron 9835 pacientes donde la proporción de adherencia fue de 90 % y en el modelo ajustado se evaluó su relación con los antecedentes de no adherencia (ORa:0,52 IC95 °/o:0,40-0,66), grupo farmacológico (2 ITIAN + 1 IP u otro) (ORa:1,22 IC95 %:0,99-1,76), dos tomas al día (ORa:1,02 IC95 %:0,74-1,40), unidades al día (≥ 3) (ORa:0,69 IC95 %:0,47-1,02), reacciones adversas a medicamentos (ORa:0,56 IC95 °%:0,40-0,78), polimedicación (ORa:1,36 IC95 %:1,00-1,85), tiempo TAR (1 a 2 años) (ORa:1,63 IC95 %:1,27-2,09),tiempo TAR (6 a 12 meses) (ORa:1,66 IC95 %:1,27-2,18), tiempo TAR (<6 meses) (ORa:1,36 IC95 %:1,03-1,78), tasa de reclamación de los medicamentos (ORa:0,42 IC95 %:0,32-0,55) y antecedentes PRUM (ORa:0,11 IC95 %:0,09-0,14). Discusión: La proporción de adherencia obtenida es superior a lo descrito para otros países (entre 60-77 %); sin embargo se encuentra que los hallazgos correspondientes al efecto de las variables farmacológicas analizadas son acordes a lo descrito en estudios previos en el tema Conclusión: Los antecedentes de no adherencia, reacciones adversas, tasa de reclamación de los medicamentos y antecedentes de problemas relacionados con el uso de medicamentos son aspectos que reducen la probabilidad de adherencia; mientras que el mayor tiempo de uso del tratamiento aumenta la misma.

Introduction: Adherence to drug treatment promotes viral suppression and reduces long-term resistance to highly active antiretroviral therapy (HAART). Objective: To determine the relationship between the pharmacological aspects and adherence to antiretroviral treatment in a Colombian IPS. Methodology: Cross-sectional analytical study in patients with HIV on antiretroviral treatment between 2012 and 2020. A multiple binary logistic regression model was used for explanatory purposes. Results: A total of 9,835 patients were analyzed where the proportion of adherence was 90 % and in the adjusted model its relationship with history of non-adherence was assessed (ORa: 0,52 95 % CI: 0,40-0,66), pharmacological group (2 NRTI + 1 PI or other) (ORa: 1,22 95 % CI: 0,99-1,76), two doses per day (ORa: 1,02 95 % CI: 0,74-1,40), units per day (≥ 3 ) (ORa: 0,69 95 % CI: 0,47-1,02), adverse drug reactions (ORa: 0,56 95 % CI: 0,40-0,78), polypharmacy (ORa: 1,36 95 % CI : 1,00-1,85), ART time (1 to 2 years) (ORa: 1,63 95 % CI: 1,27-2,09), ART time (6 to 12 months) (ORa: 1,66 95 % CI: 1,27-2,18), ART time (<6 months) (ORa: 1,36 95 % CI: 1,03-1,78), inconsistency in the claim (ORa: 0,42 95 % CI: 0,32-0,55) and PRUM history (ORa: 0,11 95 % CI: 0,09-0,14). Discussion: The proportion of adherence obtained is higher than that described for other countries (between 60-77 %); however, the findings corresponding to the effect of the pharmacological variables analysed are in line with those described in previous studies on the subject. Conclusion: The history of non-adherence, adverse reactions, inconsistencies in the claim fill history and problems related to the use of medications are aspects that reduce the probability of adherence. While the longer time of use of the treatment increases adherence.

RESUMEN

Introducción: Los ftalatos son disruptores endocrinos usados en la fabricación de múltiples productos de la industria, principalmente plásticos. El periodo fetal representa la principal ventana de vulnerabilidad, y la exposición a ftalatos en esta etapa de vida genera efectos adversos fetales y postnatales. El biomarcador más fiable para medición de ftalatos es la orina. Objetivo: Caracterizar las diferentes fuentes de exposición a disruptores endocrinos y cuantificar la concentración urinaria de ftalatos en gestantes. Materiales y métodos: Estudio transversal, observacional y descriptivo que incluye 400 gestantes que asistieron a control prenatal en las instituciones de salud Génesis y Metrosalud (Medellín-Colombia). Se caracterizaron fuentes de exposición, se recolectó muestras de orina de todas las gestantes, y cuantificó la concentración de ftalatos de 38 mujeres. Resultados: Las medias geométricas de ftalato Di(2-ethylhexyl)phthalate(DEHP), Mono-n-butyl phthalate(MnBP), Mono-2-ethyl-5-hydroxyhexyl phthalate(MEHHP) y Mono-2-ethyl-5-oxohexyl phthalate(MEOHP) fueron 162,72µg/L, 58,5 µg/L, 33,93µg/L y 31,63µg/L respectivamente. Conclusiones: La mayoría de las gestantes evaluadas han estado expuestas a lo largo de su vida a fuentes potenciales de disruptores endocrinos, presentes en químicos domésticos, tabaco y uso frecuente de cosméticos faciales y corporales. Las concentraciones de MnBP, MEHHP y MEOHP en orina de las participantes, fueron superiores a los hallazgos a nivel mundial.

Introduction: Phthalates are endocrine disruptors used in the manufacture of various industrial products, mainly plastics. The fetal period represents the principal window of vulnerability, and the exposure to Phthalates in this stage of life generates adverse fetal and post-natal effects. The most reliable biomarker for the assessment of Phthalates is urine. Objective: To characterize the different exposure sources of endocrine disruptors and quantify the urinary concentration of Phthalates in pregnant women. Materials and methods: A cross-sectional, observational, and descriptive study which included 400 pregnant women who received prenatal care in the Genesis and Metrosalud health institutions (Medellín-Colombia). Exposure sources were characterized and urine samples were collected from all pregnant women and the Phthalate concentration was quantified in 38 women. Results: The geometric measures of Phthalate Di(2-ethylhexyl)phthalate(DEHP), Mono-n-butyl phthalate(MnBP), Mono-2-ethyl-5-hydroxyhexyl phthalate(MEHHP) and Mono-2-ethyl-5-oxohexyl phthalate(MEOHP) were 162.72µg/L, 58.5 µg/L, 33.93µg/L and 31.63µg/L respectively. Conclusions: The majority of pregnant women that were evaluated were exposed to potential sources of endocrine disruptors throughout their life, which are present in household chemicals, tobacco, and frequent use of facial and body cosmetics. The concentrations of MnBP, MEHHP y MEOHP in urine of participants were higher than those found worldwide.

RESUMEN

BACKGROUND: Psoriasis is a chronic disease that seriously impacts quality of life. There are known genetic and environmental factors that influence its onset and progression. Even though there is no cure for it, there are a variety of treatments available today to control its symptoms, although many of them fail to do so substantially. OBJECTIVE: To identify the association of multiple sociodemographic, clinical, and pharmacological factors with therapeutic failure. METHODS: Observational, descriptive, cross-sectional, retrospective, and analytical study of therapeutic failure in patients with moderate or severe psoriasis between 2020 and 2021 was performed. RESULTS: In total 1051 patients with moderate or severe psoriasis were evaluated. Gender (ORa: 0.579 CI 95%: 0.382-0.878), type of therapy (biologic or non-biologic; ORa: 1.939 CI 95%: 1.242-3.027), age (ORa: 1.018 CI 95%: 1.003-1.034), days of treatment (ORa: 1 CI 95%: 0.999-1) and DLQI (ORa: 1.212 CI 95%: 1.172-1.253) are significantly associated with therapeutic failure. CONCLUSION: Being male and receiving biologic therapy are associated with a higher incidence of therapeutic failure in the treatment of moderate or severe psoriasis. The increase in DLQI increase in the probability of failure, and mayor age or days of treatment decrease in the probability of failure.

RESUMEN

Resumen Antecedentes: la variabilidad en el peso del recién nacido, ya sea como bajo peso o macrosomía, puede ocasionar morbimortalidad infantil y materna, además de ser un predictor del estado de salud a lo largo de la vida. Objetivo: determinar factores sociodemográficos, antecedentes patológicos, exposición a sustancias psicoactivas, actividad física y características alimentarias de la madre relacionados con el peso de recién nacidos en una IPS de Medellín, Colombia, en 2018. Materiales y métodos: estudio de cohorte con información de madres seguidas hasta el nacimiento de los bebés. Resultados: la edad promedio de las madres fue de 24±6 años, el peso promedio del recién nacido fue de 3150 g. Embarazo previo, consumo de lácteos y derivados, consumo de proteínas y de suplementos dietarios fueron factores presentes en madres de recién nacidos con mayor peso. Haber fumado alguna vez en la vida, antecedente de preeclampsia, parto previo, aborto en el último embarazo y consumo de alimentos ultraprocesados se presentaron en madres de recién nacidos con menor peso. Conclusiones: se recomienda a las gestantes limitar el consumo de alimentos ultraprocesados, supervisar el consumo de lácteos y derivados, proteínas y suplementos dietarios en madres con embarazos previos, antecedente de preeclampsia, abortos o hábitos como haber fumado.

Abstract Background: The variability in newborn birthweight, whether low birth weight or macrosomia, can contribute to maternal and infant morbidity and mortality as well as be a predictor of lifelong health. Objective: Determine socio-demographic factors, pathologic history, exposure to psychoactive substances, physical activity levels, and maternal diet as related to birth weight in newborns an in IPS in Medellin, Colombia 2018. Materials and Methods: Cohort study using maternal information obtained from following a sample of mothers of newborns until their infant's birth. Results: Average age of the mothers was 24±6 years and average newborn birthweight was 3150g. Previous pregnancies, consumption of dairy products, intake of protein, and use of dietary supplements were factors present in mothers of newborns with higher birthweight. Having ever smoked, history of preeclampsia, previous delivery, abortion in previous pregnancy, and intake of ultra-high processed foods (UHPF) were factors found among mothers whose infants had lower birthweight. Conclusions: It is recommended that pregnant women limit intake of highly processed foods, supervise their intake of dairy products, protein and dietary supplements in women who have had previous pregnancies, history of preeclampsia, abortions, or who have ever smoked.
