Given the high prevalence of drug resistance among patients co-infected with TB and HIV, anti-TB therapy should not be started until drug susceptibilities are known for her strain of TB.IncorrectAlthough patients co-infected with HIV and TB should ideally be screened for drug-resistant TB at the time of diagnosis, initiation of TB therapy should not be delayed. Anti-tuberculosis therapy should be started immediately, consisting of a four-drug regimen of rifampicin, isoniazid, pyrazinamide, and ethambutol.CorrectFor patients simultaneously diagnosed with HIV and active TB, the first priority is initiation of anti-tuberculosis therapy. The duration of therapy for this HIV-infected patient with pulmonary TB should be 18 months.IncorrectFor patients diagnosed with pulmonary TB who also have HIV infection, the standard duration of therapy for drug-susceptible TB is 6 months. Rapid HIV serology test result should be confirmed prior to initiation of anti-TB therapy, since she will need different medications to treat her pulmonary TB therapy if she is co-infected with HIV.IncorrectAlthough it is important to confirm her HIV infection using a second antibody test, initiation of TB therapy should not be delayed while this testing is performed.
Figure 1Figure 1 - Estimated Tuberculosis Incidence Rates 2010.Most of the TB cases in 2010 occurred in Asia and Africa. Figure 2Figure 2 - Estimated HIV Prevalence in New TB Cases, 2010.This graphic shows the HIV prevalence among new TB cases. Figure 3Figure 3 - Tuberculosis Incidence and HIV Prevalence in new TB Cases, 2009The HIV epidemic has fueled an increase in new TB cases, especially in sub-Saharan Africa.
Figure 4Figure 4 - Kaplan-Meier survival plot among multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) patients, 2005 to 2007.This retrospective observational study examined survival rates among 272 MDR-TB and 382 XDR-TB cases diagnosed in Tugela Ferry, South Africa, from 2005 to 2007. In 2010, the global tuberculosis incidence was estimated at 128 cases per 100,000 population and the total number of global cases of TB have declined since 2002. The scenario presented in this case is common in resource-limited settings where many HIV-infected persons are first diagnosed with HIV infection at the time they develop TB. Estas formas de resistencia, se encuentran muy extendidas en el mundo, dificultando el control de la TB en los A?ltimos 20 aA±os a nivel mundial. La resistencia a los medicamentos anti-TB es de tipo cromosA?mica, y fue descubierta tempranamente en los aA±os 50s, siendo observada primariamente frente a la STM (1). La apariciA?n de la epidemia del VIH en el mundo, ha limitado significativamente el control de la TB por varios factores, especialmente al incrementar la poblaciA?n susceptible a la enfermedad TB (15,16). En los paA­ses desarrollados, en todos los casos, sea cual fuere la forma clA­nica de tuberculosis, se le realiza cultivo y prueba de sensibilidad.
Sin embargo, la determinaciA?n de la sensibilidad antimicrobiana, es compleja, debido a que el M.
Por otro lado, la biologA­a molecular permite identificar genes especA­ficos de resistencia en el M. El esquema se basa en los resultados de la prueba de sensibilidad del paciente, para fA?rmacos de primera y segunda lA­nea. El esquema debe ser modificado al recibirse el resultado de la PS, pasA?ndose asA­ a un esquema individualizado. Treatment of pulmonary tuberculosis with streptomycin and para-aminosalicylic acid; a Medical Research Council investigation. Nosocomial transmission of multidrug-resistant tuberculosis to health-care workers and HIV-infected patients in an urban hospital--Florida. Unless there is reason to suspect drug resistance, initial therapy should consist of a four-drug regimen consisting of rifampicin, isoniazid, pyrazinamide, and ethambutol. Anti-TB treatment regimens generally do not differ on the basis of whether or not the patient with TB is also infected with HIV. This graph shows the TB incidence rates (new TB cases per 100,000 population), which were highest in Africa and southeast Asia.


Among all of the new TB cases in which the patient was also HIV-positive, 78% of these occurred in the African region and 13% in the South-East Asian region. The Global Plan to Stop TB 2011-2015 : Transforming the Fight – Towards Elimination of Tuberculosis.
Accordingly, this discussion will review the initiation of anti-TB therapy in patients newly diagnosed with both HIV and active TB in resource-limited settings, based on the latest World Health Organization (WHO) Guidelines.[2,3,4] The initiation of antiretroviral therapy and co-trimoxazole prophylaxis, monitoring of these patients for treatment response, and management of treatment complications such as drug toxicities and immune reconstitution inflammatory syndrome (IRIS) are reviewed in detail in separate case discussions.
For these patients, the first priority is to initiate anti-TB therapy, ideally accompanied by drug-susceptibility testing to identify patients with drug-resistant strains of TB. Extrapulmonary TB should be treated with the same regimens as pulmonary TB, but treatment duration should extend to 9 to 12 months for TB meningitis, and 9 months for bone or joint involvement.
Standard anti-TB regimens do not have significant interactions with efavirenz-based antiretroviral therapy regimens. The global plan to stop TB 2011-2015: Transforming the fight–towards elimination of tuberculosis.

Por otro lado, la TB XDR se registra desde 1999, y hasta la fecha son 494 casos reportados (Tabla 1) (14).
Este paciente era producto de uno o varios tratamientos generalmente asociado a abandono en varias oportunidades, todo ello facilitando la generaciA?n de resistencia de sus cepas (resistencia adquirida). El costo de la prueba y las capacidades actuales, aA?n no permiten su amplio uso a nivel nacional. Esto es debido a la falta de respuesta inmunitaria que limita la capacidad en formar cavidades. Sin embargo, este panorama ha cambiado, debido al adelanto tecnolA?gico, mejores polA­ticas de acceso a medicamentos, mejoras de las condiciones operacionales, mejores capacidades para un tratamiento adecuado.
Ya que no se disponen de nuevas drogas, y las correspondientes al grupo 4 A? 5 (Tabla 2) no son tan efectivas como las de los grupos 1 -3. Las indicaciones son en: i) Paciente con TB (nuevo o antes tratado) contacto intradomiciliario de caso A­ndice TB MDR, ii) Paciente con TB en esquema 1, que tiene un resultado de MODS, GRIESS o GenoType que indica resistencia a R y H.

She is diagnosed with HIV infection and pulmonary tuberculosis on the basis of a positive HIV serology result, chest radiograph findings (Figure 1), and a sputum smear that reveals acid-fast bacilli (Figure 2). Clinical trials have established that patients with TB and HIV also benefit greatly from the timely initiation of antiretroviral therapy and co-trimoxazole prophylaxis,[3] as reviewed in Management of the Patient with Newly Diagnosed HIV Infection and Active Tuberculosis: Antiretroviral Therapy and Co-trimoxazole Prophylaxis.
Empiric treatment with a standard four-drug regimen should begin immediately; the regimen can be modified as needed if susceptibility testing reveals drug resistance. Some controversy remains regarding whether or not HIV-infected persons should receive a longer course of anti-TB therapy than patients with active TB who are not co-infected with HIV.
Rifampicin, however, does have significant interactions with nevirapine and most protease inhibitors. Readers are encouraged to consult the WHO Guidelines for the programmatic management of drug-resistanttuberculosis,[4] and to seek out expert consultation, if available, for the management of patients with drug-resistant TB, particularly those patients with MDR-TB or XDR-TB.
AsA­ se define Tuberculosis multidrogo resistente (TB MDR) cuando existe resistencia a isoniacida (INH) y rifampicina (RFP), y Tuberculosis extensamente resistente (TB XDR) cuando ademA?s de las mencionadas, existe resistencia a una quinolona y a una droga inyectable. Las Ciudades de Lima y Callao concentran el 80% de los casos de TB MDR y en 89.4% de TB XDR del paA­s (14). AsA­, se encuentra que para la RFP el gen rpo B estA? asociado a > 95% de las cepas resistentes y para la INH los genes kat G, inh A en el 85% de dichas cepas. En la DISA Lima Ciudad se ha incorporado la prueba GenoType, como se mencionA? anteriormente (Figura 2). AsA­, la eficacia del Esquema 1 es del 92%, y luego esta cae para el esquema TB MDR a 85%, y mA?s para un tratamiento TB XDR a 40 a 60%.

Dosing adjustments required for use with these agents are reviewed in detail in the case Management of the Patient with Newly Diagnosed HIV Infection and Active Tuberculosis: Antiretroviral Therapy and Co-trimoxazole Prophylaxis. En el primer caso se falla al esquema de primera lA­nea, y en el segundo caso se falla al esquema de segunda lA­nea. En este contexto, la resistencia es un fenA?meno complejo, donde ademA?s de los mencionados, convergen las dificultades operativas en los servicios de salud y los factores sociales relacionados al individuo, siendo estos A?ltimos los menos abordados.
Actualmente esta prueba estA? disponible en el Instituto Nacional de Salud en el PerA? (INS), para casos especiales. AsA­ mismo, estas pruebas ayudan en pacientes que han iniciado tratamiento sin un cultivo previo, o cuando hay sospecha de fracaso (resistencia) encontrA?ndose bajo tratamiento (que pudiera impedir el aislamiento de la cepa por cultivo) (Figura 2). En la actualidad, hay dos drogas en estudio de Fase III que muestran ser eficaces: Delamanid (OPC-67683) y Bedaquiline (TMC207 A? R207910), ambas en estudio en nuestro paA­s. Sin embargo, a pesar de los esfuerzos, la TB MDR surge en todos los continentes y se expande, aun en los lugares donde la estrategia DOTS se aplicaba con eficiencia; por lo que la OMS ve la necesidad de propiciar el tratamiento con drogas de 2da lA­nea para pacientes en esta condiciA?n. Es por ello, que se considera insuficiente la sola aplicaciA?n de la estrategia DOTS para el control de la TB en el Mundo, y se comienzan a adicionar nuevas estrategias (11,12).
