A reduced grade of liver fibros-steatosis after raltegravir, maraviroc and fosamprenavir in an HIV/HCV co-infected patient with chronic hepatitis, cardiomyopathy, intolerance to nelfinavir and a marked increase of serum creatine phosphokinase levels probably related to integrase inhibitor use / Grado reducido de fibroesteatosis tras la administración de raltegravir, maraviroc y fosamprenavir en un paciente co-infectado de VIH/VHC con hepatitis crónica, cardiomiopatía, intolerancia al nelfinavir y un aumento pronunciado de los niveles de creatina fosfoquinasa sérica probablemente debido al uso del inhibidor de la integrasa

ABSTRACT
The use of new antiretroviral drugs in HIV infection is particularly important in patients with intolerance or resistance to other antiretroviral agents. Raltegravir and maraviroc represent new, important resources in salvage regimens. A reduced grade of liver fibro-steatosis after a combination of raltegravir and maraviroc (second-line) has not been studied and the mechanism by which these new drug classes induced a marked reduction of grade of liver diseases is currently unknown. In the present case report, nested in an ongoing multicentre observational study on the use of new antiretroviral inhibitors in heavy treatment-experienced HIV patients, we evaluated the correlation between a "short therapeutic regimen" raltegravir, maraviroc and fosamprenavir and liver diseases. The aim of this report is to describe the use of a three-drug regimen based on two novel-class antiretroviral agents (raltegravir and maraviroc) plus the protease inhibitor fosamprenavir, in an experienced HIV-infected patient with chronic progressive hepatitis C complicated by liver fibrosis; an overwhelming increased serum creatine kinase level occurred during treatment, and is probably related to integrase inhibitor administration. At present no information is available regarding this correlation.
RESUMEN
El uso de nuevos medicamentos antiretrovirales para la infección por VIH es particularmente importante en los pacientes con intolerancia o resistencia a otros agentes antiretrovirales. Raltegravir (RTV) y maraviroc (MRV) representan nuevos e importantes recursos en las terapias de salvamento. Un grado reducido de fibroesteatosis hepática después de una combinación de raltegravir y maraviroc (terapia de segunda línea) no ha sido estudiado, y el mecanismo por el cual estas nuevas clases de droga indujeron una marcada reducción de grado de las enfermedades hepáticas se desconoce hasta el momento. Como parte de la realización en curso de un estudio observacional multicentro acerca del uso de nuevos inhibidores antiretrovirales en pacientes de VIH altamente experimentados en el tratamiento, en el presente reporte de caso se evalúa la correlación entre un "régimen terapéutico corto" (raltegravir, maraviroc y fosamprenavir) y las enfermedades del hígado. El objetivo de este reporte es describir el uso de un régimen de tres medicamentos - basado en dos agentes antiretrovirales de nuevo tipo (raltegravir y maraviroc) además del fosamprenavir inhibidor de la proteasa - en un paciente de VIH experimentado. El paciente también sufre de hepatitis C evolutiva, progresiva, crónica, complicada por fibrosis hepática. Durante el tratamiento, se produjo un aumento extraordinario del nivel de creatina quinasa sérica, el cual probablemente esta relacionado con la administración del inhibidor de la integrasa. Actualmente no hay información disponible con respecto a esta correlación.
