[Fluconazole susceptibility of invasive Candida sp isolates as determined by three methods: Bogotá - Colombia]. / Evaluación mediante tres técnicas de susceptibilidad a fluconazol en especies de Candida aisladas en pacientes con infecciones invasoras: Bogotá - Colombia.

UNLABELLED: The frequency of invasive mycosis caused by Candida sp has increased significantly in immuno-compromised patients and in those under medical/surgical treatment; along with it, the use of azoles has fostered resistance. OBJECTIVE: To compare in vitro susceptibility techniques, susceptibility to fluconazol was determined by the M27-A2 method of CLSI (Clinical Laboratory Standard Institute), the disk diffusion technique in 90 invasive Candida sp isolated species (49 C albicans, 30 C. tropicalis, 5 C parapsilosis, 4 C . guilliermondii and 2 C. lusitaniae) and the E-test in 16 isolated. RESULTS: Over 90% of strains were susceptible to fluconazol. A straight correlation between disk-diffusion technique and the E-test was observed regarding the reference method (0.944 and 0.938, respectively). CONCLUSION: In our institution the use of fluconazol for invasive candidiasis is recommended, as well as the routine use of the disk-diffusion or E-test techniques in high complex hospitals in Colombia.

[Hepatitis B vaccine in patients with human immunodeficiency virus infection]. / Vacunación para hepatitis B en pacientes adultos infectados con virus de inmunodeficiencia humana.

Hepatitis B is a public health problem in the entire world, mainly among HIV infected people in whom the coinfection change the course, natural history and morbi-mortality of the disease. Because of this, it is imperative to design strategies to prevent hepatitis B infection in HIV patients. Vaccination is the most important tool for prevention, although its efficacy varies according to immunologic and virologic status of the patient.

La frecuencia de micosis invasoras causadas por Candida sp en pacientes inmunocomprometidos o con tratamientos médico-quirúrgicos ha aumentado y con ello, el uso de azoles, facilitando la aparición de resistencia. Objetivo: Comparar tres métodos de detección de susceptibilidad in vitro a fluconazol: el método de referencia M27-A2 del CLSI (Clinical Laboratory Standard Institute), técnica de difusión en disco a 90 aislados obtenidos en procesos infecciosos invasores (49 C. albicans; 30 C. tropicalis; 5 C. parapsilosis; 4 C. guilliermondii y 2 C. lusitaniaé) y la epsilometría (E-test®) en 16 aislados. Resultados: La susceptibilidad fue mayor a 90 por ciento. Se encontró un buen porcentaje de concordancia entre las técnicas de difusión de disco y E-test® con respecto al método de referencia (0,944 y 0,938, respectivamente). Conclusión: En nuestra institución se considera de elección fluconazol para tratar infecciones micóticas invasoras y recomendamos las técnica de difusión en disco o E-test® para determinar la susceptibilidad en la rutina en hospitales de alta complejidad en Colombia.

Because of this, it is imperative to design strategies to prevent hepatitis B infection in HIV patients. Vaccination is the most important tool for prevention, although its efficacy varies according to immunologic and virologic status of the patient.

La infección por virus de hepatitis B (VHB) representa un problema de salud pública a nivel mundial, especialmente entre las personas infectadas con el VIH, en quienes la coinfección modifica el curso y la historia natural de la enfermedad, así como la morbimortalidad, lo cual hace imperativo diseñar estrategias encaminadas a la prevención de la infección por VHB en pacientes infectados con VIH. La vacunación constituye la forma más importante de prevención, aunque su efectividad se ve alterada, de acuerdo al estado inmunológico y virológico del paciente.
