ABSTRACT

El objetivo del presente trabajo es evaluar si existe relación entre los niveles plasmáticos de efavirenz y la aparición de dislipemia como hipercolesterolemia, hipretrigliceridemia o aumento de LDL-c.Se realizaron niveles plasmáticos de efavirenz a los pacientes en tratamiento con este fármaco desde septiembre de 2012 hasta junio de 2015. Se registraron los parámetros lipídicos correspondientes a cada analítica. Las determinaciones de efavirenz se realizaron mediante cromatografía líquida de alta eficacia. Los datos se manejaron mediante el programa Quick Statistics Calculator y Excel 2007.Los niveles plasmáticos de efavirenz superiores a 4.000 ng/ml se asocian en nuestro estudio con una mayor frecuencia de niveles de colesterol superiores a 200 mg/dl.Este estudio puede ser de utilidad para aquellas zonas en las que usen pautas de tratamiento con este fármaco de manera frecuente.

The aim of this study is to evaluate if there is a relationship between plasma levels of efavirenz and the occurrence of dyslipidemia such as hypercholesterolemia, hypretrigiceridemia or increased LDL-c.Plasma levels of efavirenz were performed to patients under treatment with this drug during the period from September 2012 to June 2015. Lipid parameters corresponding to each analytical were recorded. Determinations of efavirenz were analyzed by high performance liquid chromatography. Data were managed using the Quick Statistics Calculator and Excel 2007 program.Plasma levels of efavirenz higher than 4,000 ng/ml were associated, in our study, with a higher frequency of cholesterol levels higher than 200 mg/dl.This study may be useful to those areas where treatment guidelines with this drug are used on a frequent basis.

ABSTRACT

Fundamento: Analizar el valor de los niveles plasmáticos de antígeno p24 y la carga viral (RNA, PCR), como marcadores pronóstico en una cohorte de pacientes infectados por el VIH-1, cuyo tiempo de seroconversión es desconocido.Pacientes: Se incluyeron 251pacientes, la mayoría con terapia antirretroviral, que fueron asistidos de forma consecutiva en la Unidad VIH/SIDA del Servicio de Medicina Interna del Hospital Universitario Arnau de Vilanova de Lleida.Métodos: Se hicieron estudios clínico-analíticos en el momento de inclusión (basal) y luego, cada 3 meses.En relación al antígeno p24, se establecieron 3 grupos: Grupo I, 40 pg/mL).Respecto al estudio de progresión, 34 pacientes lo hicieron. Nuevamente apreciamos una diferencia estadísticamente significativa (p=0,0039) entre el grupo I y los grupos II y III, pero no (p=0,37) entre el grupo II y el III.La comparación de los niveles plasmáticos de antígeno p24 con la carga viral por PCR pone de manifiesto una gran disparidad de resultados. Conclusiones: El nivel plasmático del antígeno p24 es un buen marcador pronóstico de supervivencia y de progresión a SIDA o muerte en enfermos infectados por el VIH-1 y su validez se prolonga por lo menos 4 años. Una cifra aislada <20 pg/mL es un signo de mejor pronóstico. No parece existir paralelismo entre los valores plasmáticos de antígeno p24 y la carga viral (AU)

ABSTRACT

BACKGROUND: Prospective study of survival and AIDS or death progression in a cohort of 251 HIV infected patients whose seroconversion time is unknown, with a main objective: To analyse p24 antigen plasmatic levels and viral load as surrogate markers. PATIENTS: 251 patients were included, most of them undergoing antiretroviral therapy, and were followed-up consecutively in the HIV/AIDS Unity of Internal Medicine Service of the Hospital Universitario Arnau de Vilanova in Lleida. METHODS: We made clinical and analytical baseline studies and every 3 months thereafter. Related to p24 antigen 3 group were established: group I, < 20 pg/mL, group 2, 20-39 pg/mL, group 3, 40 or more pg/mL. We studied survival and progression according to baseline levels over 4 year period. Regard to viral load, we just compared this with p24 antigen in the last phase of the study (third and fourth year) for technical reasons. Survival analysis was made by Kaplan-Meier estimation. Relative risk was calculated by Cox's proportional hazards model. RESULTS: During the 48 months of follow-up 55 patients died. AIDS progression risk or death was 4.8 times higher for the p24 antigen > = 40 pg/mL group than for the p24 antigen < 20 pg/mL one; the relative risk of patients with p24 antigen between 20-39 pg/mL was 2.5 times higher than those included in the group of p24 antigen < 20 pg/mL. Related to progression study, 34 patients progressed. AIDS progression risk or death for p24 antigen > = 40 pg/mL group was 7.69 times higher compared with group 2 (p24 antigen levels between 20-39 pg/mL). The comparison with viral load by PCR determination shows controversial results. CONCLUSIONS: p24 antigen plasma level is a good survival and AIDS progress or death surrogate markers in HIV infected patients, and it is useful for 4 years or more. An isolated value < 20 pg/mL is a sign of good prognosis. Parallelism between p24 antigen plasmatic level and viral load has not been observed.
