RESUMEN
Se realizó un estudio retrospectivo de casos y controles para evaluar los factores predictivos de eficacia del tratamiento combinado con interferón pegilado alfa (Peg IFN alfa) y ribavirina (RBV) contra la hepatitis C crónica en un hospital de Lima Perú, años 2006-2011. Se incluyó 34 casos consecutivos de sujetos con Respuesta Virológica Sostenida (RVS) y 36 controles temporales sin RVS, entre quienes se determinó 16 variables epidemiológicas, clínicas y de tratamiento. Se utilizó el análisis univariado de regresión logística a través del programa estadístico Epi lnfo. Los hallazgos fueron ninguno de los factores epidemiológicos, como edad, género, procedencia e in gesta alcohólica se relacionó con la RVS; de los factores clínicos evaluados, como IMC, score Child-Pugh, índice MELD, transaminasemia y grado de fibrosis, solo el estadio Child A (OR=9,45; p<0,05) se relacionó con RVS; y de los factores de tratamiento, la carga viral <= 600 mil Ul/mL (OR=2,68; p<0,05), la Respuesta Virológica Rápida (RVR; OR=58,4; p<0,01), y la Respuesta Virológica Precoz (RVP; OR=14,5; p<0,05) se asociaron con la RVS. En conclusión, los factores predictores de la RVS en los pacientes con terapia para VRC fueron la enfermedad hepática compensada (Child-Pugh A), la RVP, y sobretodo, la RVR.
ABSTRACT
We performed a retrospective study of cases and controls to assess predictors of efficacy of combination therapy with pegylated interferon alpha (Peg IFN-a) and ribavirin (RBV) for hepatitis C infection in a hospital in Lima Peru, years 2006-2011. lt included 34 consecutive cases of patients with Sustained Virological Response (SVR) and 36 controls without SVR, among whom was determined 16 variables epidemiological, clinical and treatment. We used univariate logistic regression analysis through statistical program Epi Info. The findings were none of the epidemiological factors such as age, gender, origin and alcohol intake, were associated with SVR; clinical factors evaluated, as BMI, Child-Pugh score, MELD index, transaminasemia and degree of fibrosis; only stage Child A (OR=9,45; p<0.05) was associated with SVR, and treatment factors, the load viral <=600 000 IU/ml (OR=2,68; p<0.05), Rapid Virological Response (RVR; OR=58.4; p<0.01), and Early Virological Response (EVR; OR=14,5 ; P<0.05) were associated with SVR. In conclusion, predictors of SVR in patients with HCV therapy were the compensated liver disease (Child-Pugh A), the RVP, and above all, the RVR.
