ABSTRACT

Objective Evaluating the effectiveness of antiretroviral therapy in a sample of Colombian patients diagnosed as having HIV/AIDS and being treated by the Colombian Health Social Security System (CHSSS) Methods A descriptive study was conducted among 134 HIV/AIDS patients of any age or gender who had received antiretroviral therapy in the cities of Pereira and Manizales between July 1st 2008 and June 30th 2009. The following factors were assessed from the clinical history of the patients seen in three health insurance companies: viral load, CD4 count, antiretroviral treatment regimens, prescribed daily doses of medications, length of disease evolution, duration of therapy, history of opportunistic diseases, and drug costs. Results There was male predominance (91 men cf 43 women), mean age beingf 39 years, and an average of 59 months since diagnosis. All treatment regimens were defined by each drug's defined daily dose (DDD). The therapy was effective in 74.5 percent of patients. Effectiveness was defined as being viral load < 400 copies/ml. About 79.1 percent of patients had had their viral load measured during the last 6 months. Non-adherence to treatment and a history of having acquired 2 other sexually- transmitted infections were associated with an increased risk of uncontrolled HIV infection. The average value of drugs per year per patient was $4,077.2 ± 3,043.8 U.S. dollars/year. Conclusions Non-adherence to treatment remains one of the most important issues regarding antiretroviral therapy effectiveness, so programmes intended to control HIV/AIDS must address this problem.


Objetivo Evaluar la efectividad del tratamiento antirretroviral en una muestra de pacientes con diagnóstico de VIH/SIDA en dos ciudades colombianas. Métodos Estudio descriptivo en 134 pacientes en tratamiento para VIH/SIDA de cualquier edad y género en Pereira y Manizales entre 1 de julio de 2008 y 30 de junio de 2009. Se evaluó: carga viral, conteo de linfocitos CD4, esquemas antirretrovirales, dosis diaria prescrita, tiempo evolución de enfermedad, duración de terapia, antecedentes de enfermedades oportunistas, costos de medicamentos. Resultados Predominio masculino (91 hombres vs 43 mujeres), promedio de edad: 39 años y 59 meses de evolución de la enfermedad. Todos recibían esquemas a Dosis Diarias Definidas recomendadas. La terapia era efectiva en 73,6 por ciento de los pacientes (carga viral <400 copias/ml). Se pudo establecer que la falta de adherencia al tratamiento y el antecedente de haber tenido otras 2 infecciones de transmisión sexual se asociaban con mayor riesgo de no controlar la infección por VIH. El valor promedio de los medicamentos por año por paciente fue de US$ 4 077.2 ± 3 043.8 dólares. Conclusiones La falta de adherencia al tratamiento sigue siendo uno de los problemas más importantes para garantizar efectividad, por lo cual los programas de control del VIH/SIDA deben asegurarla.

ABSTRACT

Objetivo La utilización de antibióticos ha sido objeto de abuso y se relaciona con el desarrollo de grave resistencia bacteriana.Analizar la dispensación de antibióticos de uso sistémico a nivel ambulatorio en una población colombiana entre enero de 2005 y diciembre de 2006 y la valoración de su costo económico. Métodos Estudio observacional descriptivo sobre utilización de antibióticos a partir de prescripciones dispensadas a la totalidad de usuarios que hayan recibido algún antibiótico en 10 ciudades colombianas. Se determinó dosis definida por 1 000 habitantes y día y el costo por 1 000 habitantes y día. Se analizaron las asociaciones de antibióticos empleadas comúnmente. Resultados La dosis diaria definida fue de 1,58 por 1 000 habitantes y día. Los antibióticos más dispensados fueron las penicilinas (amoxicilina dicloxacilina), seguidos de cefalosporinas de primera generación y sulfonamidas. El uso de antibióticos en presentación inyectable fue del 10,4 por ciento y 9,3 por ciento para los años 2005 y 2006 respectivamente. En 11,0 por ciento de los casos se empleó una asociación de antibióticos. El costo total de dispensación de antibióticos fue de $ 4 356 294 644 pesos (US $ 1 708 350) y el coste por mil habitantes y día de $ 3 114 pesos (US $ 1,13) en 2005 y de $ 2 564 pesos (US $ 1,00) en 2006. Discusión Las dosis diarias definidas por mil habitantes y día y el costo de los antibióticos por mil habitantes y día son menores a los reportados en otros países.


Objectives Analysing how systemic antibiotic agents were dispensed to outpatients in a Colombian population between January 2005 and December 2006 and assessing their economic cost as antibiotic use and abuse have been related to serious bacterial resistance. Methods This was a descriptive observational study of antibiotic drug use; a database was compiled from medication usage records maintained by dispensing pharmacies in 10 Colombian cities regarding the total of users who had received some type of antibiotic. The defined daily dose (DDD) and cost per 1,000 inhabitants/day were assessed. The commonly used antibiotic associations were analysed. Results DDD was 1.58 per 1,000 inhabitants per day. The antibiotics most frequently prescribed were penicillin (amoxiciline; dicloxaciline), followed by first-generation cephalosporines and sulphonamides. Injectable antibiotic use was 10.4 percent in 2005 and 9.3 percent in 2006; an association of anti-bacterial agents was used for 11 percent of the patients. Total antibiotic dispensation cost in 2005 was US$ 1,708,350 and cost per 1,000 inhabitants per day was US$ 1.13 in 2005 and US$ 1 in 2006. Conclusions DDD per 1,000 inhabitants per day and cost per inhabitant per day was low compared to other countries.
