How many times have you started to have a conversation with someone about Hepatitis C only to have it blow up in your face? Have you ever heard someone say something about Hep C that didn't seem quite right to you? You were probably right something was amiss. A discussion about Hepatitis C can...
As per Wikipedia, the definition of a stigma is as follows: "Stigma is a word that originally means a "sign", "point", or "branding mark"." Wikipedia goes on to call stigma "A badge of shame, a physical mark of infamy or disgrace." Damn that w...
Recently, the CDC (Center for Disease Control) issued a statement that all Baby Boomers should be tested for Hepatitis C. The question often comes up as to why this particular segment of people is so vulnerable. What does being born between 1945 and 1965 have to do with Hepatitis C? What was di...
Buyer Beware! There are several snake oil salesmen out there who are claiming to have cured their own Hepatitis C with herbs, supplements and parking lot gravel. Okay, maybe not the parking lot gravel but it might as well be. What you need to remember is that there are two different types of...

Introduction.
Immunosuppressed patients are at higher risks of influenza complications. This was evidenced by reports of disease outcome in solid organ transplant (SOT) recipients infected by the pandemic influenza A/09/H1N1 strain [1]–[6]. A similar risk exists in HIV infected individuals with advanced disease and low CD4 cell count but not in HAART-treated patients [7]–[11].
Immunosuppressed patients have a general trend toward impaired antibody responses to non-adjuvanted vaccines [6]. Short-term antibody responses were indeed lower following 1 or 2 doses of non-adjuvanted influenza A/09/H1N1 vaccines in HIV-infected [12], [13] and solid organ transplant (SOT) patients [13]–[15].
The extent to which adjuvanted vaccines may improve responses is thus of central interest. In HIV-infected patients, a single dose of the AS03-adjuvanted pandemic vaccine (Pandemrix®) elicited higher responses than non-adjuvanted monovalent vaccines [16]. Four weeks after 1 dose of Pandemrix®, seroresponses remained lower than in controls [17], [18] reaching similar titers after 2 doses [19]–[21]. Seroresponses remained lower in SOT recipients even after 2 doses of Pandemrix® [19], [22], [23], reflecting a more profound impact of immunosuppression on vaccine responses.
How immunosuppression affects memory responses is less well defined. In HIV-infected patients, impaired B and T cell functions cause dysfunctional germinal center interactions [24] and result in a progressive loss of B-cell memory despite antiretroviral therapy [25]–[27]. Accordingly, most HAART-treated HIV-infected adults reached a hemagglutination inhibition titer (HAI) ≥1/40 four weeks after immunization with non-adjuvanted A/09/H1N1 vaccines but only 28% remained above this threshold at 6 months [28]. How the immunosuppression of SOT patients affects memory responses is less well described.
In 2009/2010, we had followed 760 immunocompromised and 133 healthy adults immunized with 1 (healthy) or 2 (patients) doses of Pandemrix®. Four weeks after immunization, we observed similar responses in HIV-infected individuals after 2 doses as in healthy adults after 1 dose [20], and lower seroresponses in SOT recipients despite 2 immunizations [23]. To define how adjuvanted vaccines would influence antibody persistence and memory responses, we assessed the impact of 2009/2010 priming with Pandemrix® on antibody persistence and memory responses elicited in 2010/2011 by one dose of a non-adjuvanted trivalent inactivated seasonal vaccine including the same influenza A/09/H1N1 strain.
Abstract.
Background.
Memory responses require immune competence. We assessed the influence of priming with AS03-adjuvanted pandemic vaccine (Pandemrix®) on memory responses of HIV patients, kidney recipients (SOT) and healthy controls (HC).
Method.
Participants (HIV: 197, SOT: 53; HC: 156) were enrolled in a prospective study and 390/406 (96%) completed it. All had been primed in 2009/2010 with 1 (HC) or 2 (patients) doses of Pandemrix®, and were boosted with the 2010/2011 seasonal influenza vaccine. Geometric mean titres and seroprotection rates were measured 12 months after priming and 4 weeks after boosting. Primary and memory responses were directly compared in 191 participants (HCW: 69, HIV: 71, SOT: 51) followed during 2 consecutive seasons.
Results.
Most participants (HC: 77.8%, HIV: 77.6%, SOT: 66%) remained seroprotected at 12 months post-priming. Persisting A/09/H1N1 titers were high in HIV (100.2) and HC (120.1), but lower in SOT (61.4) patients. Memory responses reached higher titers in HIV (507.8) than in HC (253.5) and SOT (136.9) patients. Increasing age and lack of HAART reduced persisting and memory responses, mainly influenced by residual antibody titers. Comparing 2009/2010 and 2010/2011 titers in 191 participants followed for 2 seasons indicated lower post-2010/2011 titers in HC (240.2 vs 313.9), but higher titers in HIV (435.7 vs 338.0) and SOT (136 vs 90.3) patients.
Conclusions.
Priming with 2 doses of Pandemrix® elicited persistent antibody responses and even stronger memory responses to non-adjuvanted seasonal vaccine in HIV patients than 1 dose in healthy subjects. Adjuvanted influenza vaccines may improve memory responses of immunocompromised patients.
Please sign the ATC Salvage Therapy Petition Join us in asking Congressman Alcee Hastings and Congresswomen Maxine Waters to send a ‘Dear Colleague’ letter to Anthony Fauci, Director of NIAID, asking for the federal facilitation of apricitabine (ATC).

Researchers from Johns Hopkins Children’s Center, the University of Mississippi Medical Center and the University of Massachusetts Medical School announced today at CROI2013 the discovery of the first infant functionally cured of HIV. The baby, a female now two and a half years old, received 3 HIV medications when brought to the hospital at 30 hours old. Viral load tests were performed during the first few weeks that showed a rapidly decreasing viral load which reached ...
At the 19th International AIDS Conference (AIDS 2012) in Washington D.C., the CDC reported that only 1 out of 4 HIV patients in the U.S. have HIV under control, which is defined as complete viral suppression. Warning bells should be ringing in the scientific and HIV advocacy communities. While much progress has been made in the last three decades in the treatment of HIV, tens of thousands of people living with HIV (PLWH) are currently struggling to construct viable treat...

The HIV community has been abuzz with the August FDA approval of what had been termed “the Quad”, the second one-pill-once-a-day combination antiretroviral drug. Marketed by Gilead under the name Stribild, the drug contains two NRTIs (tenofovir and emtricitabine), an integrase inhibitor (elvitegravir) and an integrase booster (cobicistat) and is approved for use in treatment naïve patients with either drug resistant or wild type virus. In comparison to Atripla, the first...

Mission Statement
At HIV Haven we wish to provide our readers with vital cutting edge information to help expand HIV knowledge and promote activism, particularly that which works towards an end to the HIV pandemic. It is our desire to bring to you the scientific, medical and social advances that given the appropriate attention and support, could change the course of the HIV pandemic, lessen the devastating effects of HIV and AIDS, better the quality and quantity of life for people living with HIV and even yield an eventual end to the HIV pandemic. We also provide the basics of HIV transmission and treatment.
We will focus on issues such as innovative drug development, strategic activist campaigns, HIV relationships and novel HIV and HIV cure research. We also will bring you advances in Hepatitis C (HCV), a common HIV co-infection. Whether you are living with HIV/AIDS, HIV and HCV, love someone who is, are an activist, advocate, researcher, physician or just an interested party, we hope here at HIV Haven we can help you find what you are looking for.
