This 24-year-old soldier had a history of polytrauma caused by firearm missiles of a fragmentation weapon. He was referred to the Hospital Militar Central, where multiple shrapnel wounds in the head, face, thorax, and extremities were found. A brain abscess was documented and drained, and a culture grew a multidrug-resistant Acinetobacter baumannii. An appropriate antibiotic treatment was started but did not lead to a good response, and the patient died. The clinical course of the illness is presented, as is its treatment and the role of A baumannii as an etiological agent of a brain abscess. To the authors' knowledge, there have been no reported cases in the worldwide literature of brain abscess by this infectious agent.
Objetivo: Describir la resistencia a los medicamentos antirretrovirales en pacientes con segundo fracaso terapéutico en un Programa de VIH entre enero de 2011 a Diciembre de 2011. Material y métodos: Se realizó un estudio descriptivo, retrospectivo de serie de casos. Donde se describieron las mutaciones del VIH, características clínicas y hallazgos de laboratorio de los pacientes con resistencia en segundo fracaso terapéutico. Resultados: Se identificaron 30 pacientes con segundo fracaso terapéutico en el periodo de estudio. El tiempo promedio de uso de Terapia Anti-rretroviral por paciente fue de 77,2 meses (DS= 56). A 12 pacientes se les realizaron tres cambios de esquema anti-rretroviral por fracaso terapéutico y otros 2 pacientes hasta cuatro cambios de esquema. Las mutaciones más frecuentes fueron las primarias a Inhibidores de Proteasa (M46I, I54V, L10I) y a Inhibidores de Transcriptasa Inversa Análogos de Nucleósidos (Abacavir, Didanosina y Zidovudina, Estavudina).
