Objetivo: valorar el efecto de la pentoxifilina (un potente inhibidordel factor de necrosis tumoral alfa) en la supervivencia, en lahemodinámica sistémica y portal y en la función cardiaca en la cirrosisalcohólica avanzada.Diseño: estudio aleatorizado, doble-ciego, controlado con placebo.Contexto: estudio unicéntrico utilizando grupos de pacientesen paralelo para comparar pentoxifilina y placebo.Pacientes: se incluyeron 24 pacientes con cirrosis alcohólica(8 en estadio B de Child-Pugh y 16 en estadio C de Child-Pugh).Intervención: los pacientes fueron aleatorizados a recibirpentoxifilina (400 mg, 3 veces al día, n = 12) o placebo (n = 12)durante 4 semanas.Determinaciones: el objetivo principal fue la supervivencia acorto/largo plazo. Los objetivos secundarios fueron observar beneficioshemodinámicos (mejoría en la función cardiaca y/o en elíndice de resistencias vasculares sistémicas o disminución de lapresión portal).Resultados: la presión portal y la función cardiaca no se modificarony no hubo diferencias en la supervivencia a corto y largoplazo entre los grupos tratados y placebo. Los índices de resistenciavascular sistémica y cardiaco cambiaron en el grupo de pentoxifilina(de 1.721 ± 567 a 2.082 ± 622 Din.seg1 cm-5 m-2 y de4,17 ± 1,4 a 3,4 ± 0,9 lm-2, p = 0,05).Conclusiones: aunque la pentoxifilina parece producir algúnbeneficio hemodinámico a corto plazo en pacientes con cirrosis alcohólicaavanzada, no tiene efecto sobre la tasa de supervivencia, lafunción cardiaca ni sobre la presión portal en estos pacientes
Objective: to assess the effect of pentoxiphylline (a potent inhibitorof tumor necrosis factor alpha) on survival, on systemicand portal hemodynamics, and on cardiac function in patientswith alcoholic cirrhosis.Design: a randomized double-blind placebo-controlled trial.Setting: a single center using parallel groups of patients tocompare pentoxiphylline with placebo.Patients: we recruited 24 patients with alcoholic cirrhosis (8Child-Pugh B and 16 Child-Pugh C).Interventions: patients were randomly assigned to receivepentoxiphylline (400 mg tid; n = 12) or placebo (n = 12) over a 4-week period.Outcome measures: the primary outcome was to extendshort-term and long-term survival. Secondary outcomes includedhemodynamic benefits (improvement in cardiac function and/orsystemic vascular resistance index, or decrease in portal pressure).Results: portal pressure and cardiac function remained unchangedand there were no significant differences in short-term orlong-term survival between treatment and placebo groups. Thegroup on pentoxiphylline increased systemic vascular resistanceand decreased cardiac indices (from 1,721 ± 567 to 2,082 ± 622dyn.sec-1 cm-5 m-2 and from 4.17 ± 1.4 to 3.4 ± 0.9 l.m-2, p =0.05).Conclusions: although pentoxiphylline seems to providesome short-term aemodynamic benefits in patients with advancedalcoholic cirrhosis, this drug has no effect on survival or portalpressure in these patients
