Summary and Comment

Many Unaware of Their HIV-Positive Status Despite High Rates of Testing

The results illustrate the need for frequent repeat testing and comprehensive prevention efforts.
HIV counseling and testing (HCT) is an important entry point for accessing HIV treatment and prevention services. Ideally, HCT should be performed at regular intervals, especially for sexually active individuals living in high-prevalence settings. In a recent (2010) cross-sectional study, researchers assessed HCT uptake and HIV prevalence among 1300 individuals (age, >15) randomly selected from a peri-urban community near Cape Town, South Africa. Field workers visited the homes of these individuals up to five times to encourage them to undergo free HCT through a mobile HIV testing service; 88% eventually accepted.
Overall, 23% of study participants tested positive for HIV infection. Remarkably, 45% of these cases represented new diagnoses, even though most of the study participants had been tested for HIV before (71% overall; 38% in the previous year). The proportion of study participants with a new HIV diagnosis was 18% among those who had never been tested before and 9% among those who had. This proportion varied by the timing of the most recent test — 5% among those tested within the preceding year, 8% among those tested 1 to 2 years previously, and 20% among those tested >2 years previously. The prevalence of HIV infection was highest (42%) among women aged 25 to 35, whereas the proportion of positive tests that were new diagnoses was significantly higher among men (62%, vs. 37% among women).
Comment: The large proportion of individuals with new HIV diagnoses in this community, even among those who had an HIV test in the preceding year, underscores the need for frequent repeat HIV testing — and also indicates high underlying incidence rates. HCT and awareness alone are insufficient to reduce HIV acquisition.

UNAIDS has the authority and capacity to bring partners
together and create opportunities for us to share information and
reach consensus on key issues. At the Global Fund Implementers
Forum organized by UNAIDS in Dakar, April 2011, we openly
and constructively discussed our experiences of working with the
Global Fund, and, with UNAIDS support, we made sure that the
voice of civil society has been taken into account.

The world can achieve the UNAIDS vision of zero new HIV
infections, zero discrimination and zero AIDS-related deaths.
UNAIDS and the Global Fund have a critical part to play in
achieving this vision. We are stronger together.

LEY DE PREVENCION Y ASISTENCIA INTEGRAL DEL VIH/SIDA EN EL ECUADOR

http://es.scribd.com/doc/14600158/Ley-de-prevencion-y-asistencia-integral-del-VIH-SIDA-Ecuador

"LEY INTEGRAL SOBRE VIH-SIDA
 
EXPOSICIÓN DE MOTIVOS
 
El Proyecto de Ley Integral sobre VIH-SIDA, que se pone a consideración, constituye una propuesta de abordaje del problema del VIH-SIDA desde una perspectiva de desarrollo humano, que busca superar la fragmentada visión médica o biomédica de esta realidad hasta ahora imperante en el país, yproporcionar respuestas integradas que atiendan tanto la epidemia del VIH como la infección, lo cual implica modificar nuestra forma de percibir el problema y sus implicaciones.
La propuesta es producto de un proceso de creación colectiva, paciente y riguroso, extensamente discutido y validado, que comprometió esfuerzos de instituciones del Estado, organizaciones de la sociedad civil y especialistas de distintas formaciones académicas. Por iniciativa de las ONGs con trabajo en VIH-SIDA, cuya experiencia y constatación práctica de las limitaciones de la normativa vigente les impulsó a determinar la necesidad de generar una nueva legislación, es que ahora se cuenta con un proyecto elaborado participativamente y que incluye una visión integral para el abordaje del tema relacionado con el VIH-SIDA. Sus borradores han sido sometidos al estudio y análisis de diferentes ministerios y en la última fase, a la validación de múltiples actores y actoras en dos talleres en que se aprobaron los textos finales."

New Regimens to Prevent Tuberculosis in Adults with HIV Infection

 http://www.nejm.org/doi/pdf/10.1056/NEJMoa1005136

Background
Treatment of latent tuberculosis in patients infected with the human immunodeficiency
virus (HIV) is efficacious, but few patients around the world receive such treatment.
We evaluated three new regimens for latent tuberculosis that may be more
potent and durable than standard isoniazid treatment.
Methods
We randomly assigned South African adults with HIV infection and a positive tuberculin
skin test who were not taking antiretroviral therapy to receive rifapentine
(900 mg) plus isoniazid (900 mg) weekly for 12 weeks, rifampin (600 mg) plus isoniazid
(900 mg) twice weekly for 12 weeks, isoniazid (300 mg) daily for up to 6 years
(continuous isoniazid), or isoniazid (300 mg) daily for 6 months (control group). The
primary end point was tuberculosis-free survival.
Results
The 1148 patients had a median age of 30 years and a median CD4 cell count of
484 per cubic millimeter. Incidence rates of active tuberculosis or death were 3.1 per
100 person-years in the rifapentine–isoniazid group, 2.9 per 100 person-years in the
rifampin–isoniazid group, and 2.7 per 100 person-years in the continuous-isoniazid
group, as compared with 3.6 per 100 person-years in the control group (P>0.05 for
all comparisons). Serious adverse reactions were more common in the continuousisoniazid
group (18.4 per 100 person-years) than in the other treatment groups (8.7
to 15.4 per 100 person-years). Two of 58 isolates of Mycobacterium tuberculosis (3.4%)
were found to have multidrug resistance.
Conclusions
On the basis of the expected rates of tuberculosis in this population of HIV-infected
adults, all secondary prophylactic regimens were effective. Neither a 3-month course
of intermittent rifapentine or rifampin with isoniazid nor continuous isoniazid was
superior to 6 months of isoniazid. (Funded by the National Institute of Allergy and
Infectious Diseases and others; ClinicalTrials.gov number, NCT00057122.)

Reunión de Alto Nivel sobre el Sida de 2011

http://www.unaids.org/es/aboutunaids/unitednationsdeclarationsandgoals/2011highlevelmeetingonaids/

"La respuesta mundial al sida continúa dando frutos: un número sin precedente de personas accede al tratamiento y las tasas de nuevas infecciones por el VIH han descendido en casi un 25%

En el momento en que se cumplen 30 años desde que se registrara el primer caso de sida (5 de junio de 1981), el ONUSIDA calcula que 34 millones de personas [30,9 millones- 36,9 millones] viven con el VIH en todo el mundo y que prácticamente 30 millones [25 millones-33 millones] han fallecido por causas relacionadas con el sida.

NUEVA YORK/Ginebra, 3 de junio de 2011—A finales de 2010, en torno a 6,6 millones de personas recibían terapia antirretrovírica en países de ingresos bajos y medios, lo que supone una cifra casi 22 veces superior a la de 2001, según un nuevo informe presentado hoy por el Programa Conjunto de las Naciones Unidas sobre el VIH/Sida (ONUSIDA), titulado Treinta años de sida: las naciones en un punto clave del camino (en inglés).

En 2010, un número récord de 1,4 millones de personas inició por primera vez el tratamiento antirretrovírico, una cifra muy superior a cualquier año previo. Según el informe, al menos 420.000 niños recibían terapia antirretrovírica a finales de 2010, lo que supone un aumento superior al 50% respecto a los 275.000 que lo hicieron en 2008.
 “El acceso al tratamiento transformará la respuesta al sida en la próxima década. Debemos invertir en acelerar el acceso a la terapia del VIH y en encontrar nuevas opciones de tratamiento”, afirmó Michel Sidibé, director ejecutivo del ONUSIDA. “La terapia antirretrovírica es ahora más que nunca un gran motor para el cambio: no solo impide que las personas mueran, sino que también evita nuevas infecciones por el VIH en hombres, mujeres y niños”.

Esta declaración alude a los resultados del ensayo HPTN052 , publicados el 12 de mayo de 2011, que demostraron que si una persona que vive con el VIH se adhiere a una posología antirretrovírica efectiva, el riesgo de transmitir el virus a su pareja sexual seronegativa se puede reducir en un 96%.
 “Los países deben hacer uso de lo mejor que la ciencia puede ofrecer para evitar nuevas infecciones por el VIH y muertes relacionadas con el sida”, afirmó la Vicesecretaria General de las Naciones Unidas, Asha-Rose Migiro. “Estamos en un momento crucial en la respuesta al sida. El objetivo de alcanzar el acceso universal a la prevención, el tratamiento, la atención y el apoyo relacionados con el VIH para 2015 debe convertirse en una realidad”.

Las iniciativas de prevención del VIH están dando frutos
Según el informe, la tasa mundial de nuevas infecciones por el VIH se redujo en prácticamente un 25% entre 2001 y 2009: en la India, este descenso fue superior al 50%; y en Sudáfrica, al  35%. Ambos países albergan al mayor número de personas que viven con el VIH en sus continentes.
El informe concluye que en la tercera década de la epidemia, las personas estaban comenzando a adoptar comportamientos sexuales más seguros, lo que refleja la repercusión de las iniciativas de prevención y sensibilización. Sin embargo, todavía hay escollos importantes. Los varones jóvenes suelen estar más informados sobre la prevención del VIH que sus coetáneas: las últimas encuestas demográficas y de salud arrojaron que en torno al 74% de éstos sabían que los preservativos eran efectivos para prevenir la infección por el VIH, mientras que entre las jóvenes, esta cifra solo era del 49%.
En los últimos años se han producido avances importantes en la prevención de nuevas infecciones entre niños gracias al aumento del número de mujeres embarazadas seropositivas que ha accedido a la profilaxis antirretrovírica durante el embarazo, el parto y la lactancia. El número de nuevas infecciones por el VIH en niños fue en 2009 un 26% menor que en 2001.
Unos 115 países de ingresos bajos y medios están ofreciendo un tratamiento óptimo a las mujeres embarazadas que viven con el VIH siguiendo las recomendaciones de la Organización Mundial de la Salud. Sin embargo, 31 países todavía utilizan terapias subóptimas en muchos de sus programas. El ONUSIDA insta a todas estas naciones a revisar sus directrices de tratamiento y hacer la transición a los tratamientos óptimos recomendados por la OMS."

"En sida no ha sido erradicado, todavía quedan retos importantes

Según las últimas estimaciones del ONUSIDA, 34 millones de personas [30,9 millones-36,9 millones] vivían con el VIH a finales de 2010, y cerca de 30 millones [25 millones-33 millones] habían muerto por causas relacionadas con el sida desde que se registrara la enfermedad por primera vez hace 30 años.
A pesar de la expansión del acceso a la terapia antirretrovírica, todavía hay un gran déficit de tratamiento. A finales de 2010, nueve millones de personas elegibles para seguir la terapia no podían acceder a ella. El acceso para los niños es aún más limitado que para los adultos: en 2009, solo el 28% de los niños elegibles recibían tratamiento, mientras que para las personas de todas las edades la cobertura era del 36%.
Aunque la tasa de nuevas infecciones por el VIH ha descendido globalmente, el número total de infecciones sigue siendo muy alto, en torno a 7.000 cada día. La reducción global de la tasa de nuevas infecciones oculta las variaciones regionales. Según el informe, África subsahariana y Asia sudoriental fueron las regiones donde el descenso en el número de nuevas infecciones superó la media, mientras que en América Latina y el Caribe fueron más modestos, de apenas un 25%. Por otro lado, esta tasa ha aumentado en Europa oriental, Oriente Medio y África septentrional.
En prácticamente todos los países la prevalencia del VIH en las personas más expuestas al riesgo de infección (hombres que tienen relaciones sexuales con hombres, usuarios de drogas inyectables, profesionales del sexo y sus clientes, y personas transgénero) es mayor que en otra poblaciones. El acceso de estos grupos a la prevención y el tratamiento es generalmente menor debido a la existencia de leyes punitivas y discriminatorias, así como al estigma y la discriminación. Según los datos de abril de 2011, 79 países, territorios y áreas penalizan las relaciones homosexuales consentidas; 116 países, territorios y áreas penalizan algún aspecto del trabajo sexual; y 32 países tienen leyes que permiten la pena de muerte por delitos relacionados con drogas.
Según el informe, las desigualdades de género también siguen siendo un gran obstáculo para responder de manera efectiva al VIH. El virus es la principal causa de muerte de mujeres en edad reproductiva, y más de un cuarto (26%) de todas las nuevas infecciones se dan en mujeres de entre 15 y 24 años.
Se reducen los recursos destinados al sida
Según el informe, las inversiones en la respuesta al VIH en los países de ingresos bajos y medios prácticamente se multiplicaron por 10 entre 2001 y 2009, de USD 1.600 millones a USD 15.900 millones. Sin embargo, los recursos internacionales destinados al VIH se redujeron en 2010. Muchos países de ingresos bajos siguen dependiendo ampliamente de financiación externa. En 56 países, los donantes internacionales cubren, como mínimo, el 70% de los recursos para el VIH.
“Me preocupa que las inversiones internacionales se estén reduciendo en un momento en el que la respuesta al sida está consiguiendo resultados para las personas”, afirmó Sidibé. “Si no invertimos ahora, lo pagaremos con creces en el futuro”.
En 2011, el ONUSIDA y sus asociados propusieron un marco de inversión que concluyó que para 2015 se necesita una inversión de al menos USD 22.000 millones, 6.000 más de los que se dispone actualmente. La repercusión es mayor cuando estas inversiones se destinan a un conjunto de programas prioritarios que se basan en un tipo de epidemia nacional. Se estima que con una inversión de esta magnitud se conseguirán evitar hasta 2020 diez millones de nuevas infecciones por el VIH y 7,4 millones de muertes relacionadas con el sida. El número de nuevas infecciones descendería de unos 2,5 millones en 2009 a en torno a un millón en 2015.
Perspectivas sobre el sida de líderes de todo el mundo
El informe contiene comentarios de 15 líderes de la respuesta mundial al sida, entre otros, el presidente de Sudáfrica, Jacob Zuma; el ex-presidente de los Estados Unidos, Bill Clinton; el ex-presidente de Brasil Luiz Inácio Lula da Silva; el presidente de Malí, Amadou Tounami Touré; y Jean Ping, presidente de la Comisión de la Unión Africana. Estos comentarios versan sobre áreas diversas, como la financiación para el sida, la cooperación Sur-Sur, el liderazgo de los jóvenes, la capacitación de la mujer, las poblaciones más afectadas, el consumo de drogas inyectables, los derechos humanos, el estigma y la discriminación, y la integración de sistemas.
Los jóvenes lideran la revolución de la prevención del VIH
Treinta años de sida: las naciones en un punto clave del camino también incluye un artículo sobre un acto que se celebró recientemente en Robben Island, Sudáfrica, donde el arzobispo Desmond Tutu, copresidente de la Comisión de alto nivel del ONUSIDA sobre la prevención del VIH, pasó el testigo del liderazgo en la respuesta al sida a una nueva generación de jóvenes.
Según el informe, algunos de los mayores avances en la prevención del VIH se han producido entre los jóvenes. Los datos indican que cada vez son más los jóvenes que, en muchos de los países más afectados, están optando por retrasar su iniciación sexual y evitan aquellas conductas sexuales que pueden exponerles a un mayor riesgo de infección."

HIV Therapy Dramatically Cuts Transmission in Heterosexual Pairs

      "By Michael Smith, North American Correspondent, MedPage Today
Published: May 12, 2011
 
Triple-drug therapy dramatically reduced transmission of HIV in heterosexual couples when one partner is infected and the other is not, results of a randomized trial showed.
Treating the infected partner in these discordant couples reduced transmission by 96%, compared with no treatment, according to Myron Cohen, MD, of the University of North Carolina Chapel Hill, and colleagues.
The $73 million trial had been slated to finish in 2015 but was stopped early after those clear-cut results were found by the study's data safety monitoring board during a planned interim review.
A series of mathematical models and observational studies have suggested that treatment of HIV can reduce transmission, and other studies have suggested that anti-HIV drugs might be used as prophylaxis.
But this is the "first, rather dramatic, randomized trial in discordant couples," according to Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, one of the sponsors of the so-called HPTN 052 trial.
It "nails the concept down rather nicely," he said in a telephone media conference.
Outside experts hailed the trial as a giant step forward.

"This study is another milestone in the history of HIV," said John Bartlett, MD, of Johns Hopkins. "The concept of treatment for prevention is proven."

"Patients can take the drugs for their own health and for public health," Bartlett added in an email to ABC News/MedPage Today.

The findings have the potential to transform approaches to the treatment and prevention of HIV," according to Mark Kline, MD, of Baylor College of Medicine in Houston.

Kline noted in an email to ABC News/MedPage Today that a trial in the mid-1990s showed that administering a single anti-HIV drug to pregnant women could prevent mother-to-child transmission of the virus.

That finding had "an immediate and direct impact on public health policies" and led many experts to think that treatment might prevent infection in other settings, he said.

"Now, we have conclusive evidence from a prospective, randomized treatment trial in support of that contention," Kline said.

Indeed, the findings "must serve as a clarion call" for expanded access to treatment, according to Mitchell Warren, executive director of the New York-based AIDS Vaccine Advocacy Coalition.
"We now have evidence from a randomized trial confirming what has been seen in observational settings: (antiretroviral) treatment is prevention," Warren told MedPage Today in an email.
The study, conducted by the HIV Prevention Trials Network, began in April 2005 and enrolled 1,763 couples, 97% of them heterosexual, in nine countries.
All the HIV-infected participants -- 890 men and 873 women -- had relatively intact immune systems, with CD4-positive T-cell counts between 350 and 550 per cubic millimeter and were not eligible at the time for HIV treatment based on their local guidelines.
They were randomly assigned to get immediate treatment or to wait until their CD4 counts fell to 250 or they had an AIDS-defining event.
All told, the review found 39 cases of HIV infection among the previously uninfected partners, and genetic analysis showed that 28 of those came from the infected partner. (Seven did not, and four are still being analyzed.)
But 27 of the linked infections occurred in the deferred treatment group and just one in the immediate therapy arm, a difference that was significant at P<0.0001.
All participants in the deferred treatment arm are now being offered triple-drug therapy regardless of their CD4 count, Cohen told reporters during the telephone media conference.
He said that the original plan for the study was to have homosexual couples included, but very few agreed to take part. For that reason, he said, it would be a "mistake" to assume this finding would apply to men who have sex with men.
Cohen added that the trial shows that even with a relatively intact immune system, transmission can occur. "You can't look at a high CD count and make the assumption that transmission is not going to occur," he said.
HIV transmission risk is linked to the amount of the virus in the blood, the so-called viral load, but many physicians will assume that if the CD4 count is relatively high, they can "let it go," Fauci said. The study investigators are currently analyzing viral load data from the trial, he said.
The treatment regimens used in the trial varied depending on the location of patients, Fauci said, with 11 different antiretroviral drugs employed in various combinations.
The researchers also found that 17 cases of extrapulmonary tuberculosis occurred in the HIV-infected partners in the deferred treatment arm and just three in the immediate treatment arm. The difference was significant at P=0.0013.
There were 23 deaths -- 10 in the immediate treatment group and 13 in the deferred treatment arm -- but the difference was not significant."

Early HIV Treatment Associated with Greatly Reduced Transmission to Partners

Estimados colegas , aqui les dejo el link para poder revisarlo:

Saludos

Dr. Carlos Erazo

A 10-year study on early HIV treatment has been stopped prematurely after a monitoring board found convincing evidence that it "can have a major impact on reducing HIV transmission," said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, in an NIH announcement Thursday.
Called HPTN 052, the international study was conducted primarily among some 1800 heterosexual couples. One partner in each couple was uninfected at entry. Infected partners were randomized either to immediate treatment with a three-drug antiretroviral regimen or to deferred treatment (until CD4 counts fell below 250 per cubic millimeter or an AIDS-related event occurred).
There were 28 new infections linked to partners, 27 of which occurred among the deferred-treatment group, giving a relative reduction in transmission of 96%.
Dr. Carlos del Rio of Journal Watch HIV/AIDS Clinical Care commented that the findings "prove once and for all that antiretroviral therapy not only is good for the individual but it is also good for society, as it reduces HIV transmission."

Findings Result from NIH-funded International Study


Men and women infected with HIV reduced the risk of transmitting the virus to their sexual partners by taking oral antiretroviral medicines when their immune systems were relatively healthy, according to findings from a large-scale clinical study sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
The clinical trial, known as HPTN 052, was slated to end in 2015 but the findings are being released early as the result of a scheduled interim review of the study data by an independent data and safety monitoring board (DSMB). The DSMB concluded that it was clear that use of antiretrovirals by HIV-infected individuals with relatively healthier immune systems substantially reduced transmission to their partners. The results are the first from a major randomized clinical trial to indicate that treating an HIV-infected individual can reduce the risk of sexual transmission of HIV to an uninfected partner.
“Previous data about the potential value of antiretrovirals in making HIV-infected individuals less infectious to their sexual partners came largely from observational and epidemiological studies,” said NIAID Director Anthony S. Fauci, M.D. “This new finding convincingly demonstrates that treating the infected individual—and doing so sooner rather than later—can have a major impact on reducing HIV transmission.”
Led by study chair Myron Cohen, M.D., director of the Institute for Global Health and Infectious Diseases at the University of North Carolina at Chapel Hill, HPTN 052 began in April 2005 and enrolled 1,763 couples, all at least 18 years of age. The vast majority of the couples (97 percent) were heterosexual, which precludes any definitive conclusions about effectiveness in men who have sex with men. The study was conducted at 13 sites in Botswana, Brazil, India, Kenya, Malawi, South Africa, Thailand, the United States and Zimbabwe. The U.S. site collected only limited data because of difficulties enrolling participants into the study. However, data from one serodiscordant couple at the site was included in the DSMB’s analysis. At the time of enrollment, the HIV-infected partners (890 men, 873 women) had CD4+ T-cell levels—a key measure of immune system health—between 350 and 550 cells per cubic millimeter (mm³) within 60 days of entering the study. The HIV-uninfected partners had tested negative for the virus within 14 days of entering the study.
The investigators randomly assigned the couples to either one of two study groups. In the first group, the HIV-infected partner immediately began taking a combination of three antiretroviral drugs. In the second group (the deferred group), the HIV-infected partners began antiretroviral therapy when their CD4 counts fell below 250 cells/mm³ or an AIDS-related event, such as Pneumocystis pneumonia, occurred. Throughout the study, both groups received HIV-related care that included counseling on safe sex practices, free condoms, treatment for sexually transmitted infections, regular HIV testing, and frequent evaluation and treatment for any complications related to HIV infection. Each group received the same amount of care and counseling.
In its review, the DSMB found a total of 39 cases of HIV infection among the previously uninfected partners. Of those, 28 were linked through genetic analysis to the HIV-infected partner as the source of infection. Seven infections were not linked to the HIV-infected partner, and four infections are still undergoing analysis. Of the 28 linked infections, 27 infections occurred among the 877 couples in which the HIV-infected partner did not begin antiretroviral therapy immediately. Only one case of HIV infection occurred among those couples where the HIV-infected partner began immediate antiretroviral therapy. This finding was statistically significant and means that earlier initiation of antiretrovirals led to a 96 percent reduction in HIV transmission to the HIV-uninfected partner. The infections were confirmed by genetic analysis of viruses from both partners.
Additionally, 17 cases of extrapulmonary tuberculosis occurred in the HIV-infected partners in the deferred treatment arm compared with three cases in the immediate treatment arm, a statistically significant difference. There were also 23 deaths during the study. Ten occurred in the immediate treatment group and 13 in the deferred treatment group, a difference that did not reach statistical significance.
The study was designed to evaluate whether antiretroviral use by the HIV-infected individual reduced HIV transmission to the uninfected partner and potentially benefited the HIV-infected individual as well. Additionally, the study was designed to evaluate the optimal time for a person infected with HIV to initiate antiretrovirals in order to reduce HIV-related sickness and death. Based on their analysis, the DSMB recommended that the deferred study arm be discontinued and that the study participants be informed of the trial’s outcome.
“We want to thank the study participants for making such an important contribution in the fight against HIV/AIDS. We think that these results will be important to help improve both HIV treatment and prevention,” said Dr. Cohen.
Study participants are being informed of the results. Individuals who became HIV-infected during the course of the study were referred to local services for appropriate medical care and treatment. HIV-infected participants in the deferred treatment group will be offered antiretroviral therapy.  The study investigators will continue following the study participants for at least one year.
The study was conducted by the HIV Prevention Trials Network, which is largely funded by NIAID with additional funding from the National Institute on Drug Abuse and the National Institute of Mental Health, both part of the NIH. Additional support was provided by the NIAID-funded AIDS Clinical Trials Group. The antiretroviral drugs used in the study were made available by Abbott Laboratories, Boehringer Ingelheim Pharmaceuticals, Inc., Bristol-Myers Squibb, Gilead Sciences, GlaxoSmithKline/Viiv Healthcare and Merck & Co., Inc.
The 11 HIV drugs that were used in various combinations included the following:
  • atazanavir (300 mg once daily)
  • didanosine (400 mg once daily)
  • efavirenz (600 mg once daily)
  • emtricitabine/tenofovir disoproxil fumarate (200 mg emtricitabine/300 mg tenofovir disoproxil fumarate once daily)
  • lamivudine (300 mg once daily)
  • lopinavir/ritonavir 800/200 mg once daily (QD) or lopinavir/ritonavir 400/100 mg twice daily (BID)
  • nevirapine (200 mg taken once daily for 14 days followed by 200 mg taken twice daily)
  • ritonavir (100 mg once daily, used only to boost atazanavir)
  • stavudine (weight-dependent dosage)
  • tenofovir disoproxil fumarate (300 mg once daily)
  • zidovudine/lamivudine (150 mg lamivudine/300 mg zidovudine taken orally twice daily)
In an ongoing international clinical study called Strategic Timing of Antiretroviral Therapy, NIAID is examining the optimal time for asymptomatic HIV-infected individuals to begin antiretrovirals.
