ABSTRACT

ABSTRACT The addition of the new protease inhibitors (PIs) to peg-interferon (IFN) and ribavirin (RBV), approved for chronic hepatitis C, has clearly improved sustained virological response (SVR) rates although several adverse events have been reported with this regimens, including mild hematological toxicity. Moreover, severe pancytopenia and aplastic anemia during triple therapy with telaprevir has recently been described in seven patients. We report here two cases of severe agranulocytosis/aplastic anemia using boceprevir or simeprevir in interferon-based combination and 2 additional cases of severe myelosupression in IFN-free therapy with sofosbuvir and simeprevir plus RBV. Our observations suggest that PIs could have a sort of class-effect in developing severe hematologic toxicity or, at least, an additive interaction with other potentially myelotoxic agents such as IFN or RBV that are used in the classical regimens against HCV. Unfortunately, the mechanisms behind this phenomenon are currently unknown. In conclusion, given the lifethreatening character of these complications, close monitoring is mandatory in patients under PIs based therapy to promptly detect serious hematological toxicities and to carefully evaluate treatment discontinuation. Prospective studies assessing the usefulness of RBV in the era of new IFN-free combinations are needed.

ABSTRACT

Se realizó un estudio prospectivo, descriptivo con el objetivo de evaluar la eficacia de la conización cervical con radiofrecuencia en pacientes con neoplasia intraepitelial cervical III que consultaron a Profamilia en Medellín, Colombia entre Julio 1996 y Mayo 1997. Se ingresaron un total de 60 pacientes, en quienes la biopsia guiada por colposcopia mostró este diagnóstico. El promedio de edad fue de 31.5 años. El factor de riesgo más encontrado fue el inicio temprano de las relaciones sexuales en 31.6 por ciento. El 51.7 por ciento de las pacientes no presentaron dolor, el 78.3 por ciento no tuvieron sangrado o este fue leve. La concordancia entre la biopsia y el cono para hacer el diagnóstico de NIC III fue del 96.5 por ciento y la asociación entre NIC III y PVH fue del 36.7 por ciento. El 96.7 por ciento por ciento de las pacientes que cumplieron con el criterio de seguimiento presentaron curación y solo el 3.3 por ciento tuvieron complicaciones tardías (estenosis).En conclusión, la conización es una técnica eficaz para el diagnóstico y tratamiento del NIC III...
