An aggressive form of HIV uncovered in Cuba
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus. One such recombinant variant observed in patients in Cuba appears to be much more aggressive than other known forms of HIV. Patients progress to AIDS within three years of infection -- so rapidly that they may not even realize they were infected. (2015-02-12)

Where are HIV diagnoses made?
In the first study to comprehensively describe where people are diagnosed with HIV in England, Wales, and Northern Ireland, investigators found that an increasing proportion of HIV diagnoses are being made outside of sexual health clinics, which is in line with evolving HIV testing guidelines. (2018-05-11)

Existing drugs may limit damage caused by HIV
Yale researchers have identified four drugs that may help minimize the long-term health effects of HIV infection, they report June 23 in the Journal of Clinical Investigation. (2020-06-23)

Anti-HIV protein from blue-green algae also inhibits Ebola infection
Researchers have discovered that a bacterial protein known to reduce the ability of the human immunodeficiency virus (HIV) to infect cells also inhibits infection by the Ebola virus. (2003-03-03)

Measures needed to reduce bloodborne infections in Irish prisons
There is an urgent need for increased infection control and harm reduction measures to reduce the transmission of hepatitis B and C viruses, and HIV in Irish prisons, concludes a study in this week's BMJ. (2001-11-22)

HIV drugs provide added benefit of protecting against hepatitis B virus
In a study involving 2,400 men who have sex with men who were also enrolled in the Multicenter AIDS Cohort Study, researchers report that men with HIV who were treated effectively with HIV therapy were the least likely (80 percent less likely) to get infected with HBV over a median follow-up of approximately 9.5 years. (2015-10-12)

Study suggests life insurance should cover people treated for HIV
Authors of a Swiss study in this week's issue of The Lancet highlight how people effectively treated for HIV-1 infection with highly active antiretroviral therapy (HAART) have similar or lower mortality rates than patients successfully treated for cancer--calling into question the decision of insurance companies in many developed countries to not offer life insurance for people with HIV/AIDS. (2003-09-11)

Herpes drug inhibits HIV replication, but with a price
The anti-herpes drug acyclovir can also directly slow down HIV infection by targeting the reverse transcriptase enzyme, researchers report. This beneficial effect does pose a risk though, as HIV-infected cells treated with acyclovir promote the emergence of multi-drug resistant HIV variants. (2008-11-06)

Highly active HIV antibody restricts development of viral resistance
A research team led by Univ.-Prof. Dr. Florian Klein of the Institute of Virology of the University Hospital Cologne and the German Center for Infection Research (DZIF) has identified a new highly active antibody targeting HIV. Whereas the development of viral resistance limits the efficacy of previously described HIV antibodies, the newly identified antibody 1-18 can continuously suppress viral replication. 1-18 there-fore has high potential for successful application in the prevention and treatment of HIV infection.

Genetic mutation linked to West Nile virus infection
A genetic mutation that protects against HIV increases the risk of developing clinical West Nile virus infection, according to a new study appearing online on January 9th in the Journal of Experimental Medicine. (2006-01-09)

HIV grows despite treatment, study finds
HIV can continue to grow in patients who are thought to be responding well to treatment, according to research by the University of Liverpool. (2015-08-04)

Circulating blood antibodies are not required for HIV protection
The study, published by Cell Press in the February issue of the journal Immunity, demonstrates that a vaccine which stimulates production of specific anti-HIV antibodies in the vaginal tissue was sufficient to protect monkeys from exposure to live virus. The results may also help to explain why a few individuals who lack anti-HIV antibodies in the blood are able to resist infection, even when they are repeatedly exposed to HIV. (2011-02-10)

First UK cases of previously rare disease reported in gay men
The first UK cases of a previously rare disease have been reported in gay men, reveals an editorial in the journal Sexually Transmitted Infections. (2005-03-30)

HIV infection progresses to AIDS quicker in developing countries
Researchers from the Johns Hopkins Bloomberg School of Public Health, the Armed Forces Research Institute of Medical Sciences and Chiang Mai University in Thailand found that the progression from HIV infection to AIDS and death from AIDS is more rapid in people living in developing countries than those living in the United States and Europe. (2004-04-27)

Defensins ward off HIV in two ways
Defensins are proteins with anti-HIV activity, but the mechanism was unknown. In the JCI, researchers analyze how alpha-defensin-1 inhibits HIV infection. They show that alpha-defensin-1 fights HIV two ways. When viral burden is low, alpha-defensin-1 directly inactivates HIV virus. When serum is present, alpha-defensin-1 acts on cells to block HIV uptake by the cell and viral replication and integration. Developing defensin-like drugs for prevention of HIV and therapeutic use may be beneficial. (2005-02-17)

Routine HIV screening in the ED is cost effective and well liked by patients
Using new and highly publicized CDC guidelines for HIV screening, a university-based Emergency Department implemented opt-out screening in Washington, D.C., where HIV infection rates are known to be high. Fully 60 percent of the patients agreed to testing, a high percentage that may have been influenced by an ongoing district-wide campaign encouraging HIV screening. Over 4000 patients were eligible for free screening and almost 2500 were tested, with 26 patients (1 percent) having a preliminary positive result. (2007-05-16)

Different HIV rates among gay men and straight people not fully explained by sexual behavior
Differences in sexual behaviours do not fully explain why the US HIV epidemic affects gay men so much more than straight men and women, claims research published ahead of print in the journal Sexually Transmitted Infections. In 2005, over half of new HIV infections diagnosed in the US were among gay men, and up to one in five gay men living in cities is thought to be HIV positive. (2007-09-13)

'Significant' proportion of HIV positive patients may not be telling NHS staff about their infection
A significant proportion of HIV positive patients may not be disclosing their infection to NHS staff, when turning up for treatment at sexual health clinics, suggests preliminary research published online in the journal Sexually Transmitted Infections. (2013-02-13)

Dual testing better for monitoring new cases of HIV
Johns Hopkins researchers will present results showing that tighter, dual testing standards work better for accurately distinguishing between new and old cases of HIV. (2005-02-25)

Prevalence of 'risky' sex among gay men doubled in Scotland over six years

HIV risk higher among Indian women who are abused by husbands
Married women in India who experience physical and sexual violence from their husbands have an increased risk of HIV infection, compared with women who are not abused by their husbands, according to a study in the August 13 issue of JAMA, a theme issue on violence and human rights. (2008-08-12)

Protein critical to early stages of cellular HIV infection identified
A Tokyo Medical and Dental University (TMDU) -led research team identified a protein, MELK, required for the HIV-1 virus to efficiently infect its target cells. MELK, produced by the cell, is necessary for removal of the protein coat around the HIV-1 virus, which is essential for the infection process. The team further revealed that MELK modifies the protein coat at a specific location to promote its removal. These findings offer a potential new target for anti-HIV treatment. (2017-08-08)

Researchers Identify Mechanism By Which T Cells Resist Infection By HIV-1
Researchers have discovered that a new method of growing CD4+ T cells renders them resistant to HIV- 1 infection by preventing the expression of a recently discovered coreceptor essential for HIV- 1 infection, as reported in today's issue of SCIENCE. (1997-04-10)

NIH funding renewed for VA study of alcohol and HIV/AIDS interactions
The Veterans Aging Cohort Study has received a five-year, $13-million continuation award from the National Institute on Alcohol Abuse and Alcoholism to examine the impact of aging and alcohol use among those with and without chronic HIV infection. (2006-09-27)

George Mason research team uncovers new factor in HIV infection
A George Mason University researcher team has revealed the specific process by which the HIV virus infects healthy T cells -- a process previously unknown. The principal investigator, HIV researcher Yuntao Wu, says he hopes this breakthrough will start a new line on inquiry into how researchers can use this knowledge to create drugs that could limit or halt HIV infection. (2011-08-24)

Researchers uncover new piece of the HIV puzzle
New research has revealed that a key immune system component -- innate lymphoid cells (ILC) -- is destroyed during acute HIV infection. This may play a key role in understanding the progression of the disease from HIV to AIDS. HIV affects more than 35 million people worldwide. (2016-02-03)

Adverse effects of antiretroviral treatment for HIV infection
It is well known that treatment of HIV-1 infection (that may lead to AIDS) has side effects, but there are few studies of how many people having treatment are affected by adverse reactions. In a study of 1160 people receiving antiretroviral treatment, published in The Lancet this week, Jacques Fallon and colleagues from the Swiss HIV Cohort Study in Zurich, Switzerland, report (2001-10-18)

Study finds innate protein that restricts HIV replication by targeting lipid rafts
A recent study from the George Washington University suggests that the innate protein AIBP restricts HIV-1 replications by targeting the lipid rafts the virus relies on. (2020-02-10)

No increase in sexual risk taking among gay men in HIV-study
Canadian gay men participating in the world's first test of a vaccine to prevent HIV did not appear to become more risky sexually out of false hope that the vaccine being tested would protect them from infection. (2005-02-14)

Chemsex linked with increased diagnoses of HIV and other sexually transmitted infections
Chemsex -- the use of crystallized methamphetamine, mephedrone, γ-hydroxybutyrate or γ-butyrolactone and to a lesser extent cocaine and ketamine to facilitate sex -- has emerged as a new phenomenon in the UK and across Europe among gay, bisexual and other men who have sex with men (GBMSM). (2018-05-23)

Continued Prophylactic Treatment Of P. Marneffei Can Prevent Relapse
A large number of patients in Thailand who are infected with the Human Immunodeficiency Virus (HIV) have become ill from a previously very rare fungus called Penicillium Marneffei. Giving prophylactic itraconazole, an anti-fungal drug, to patients who have been treated for P. Marneffei, a potentially fatal fungal infection, can prevent a relapse of the infection. (1998-12-10)

Van to patrol Baltimore streets offering free HIV urine testing
Johns Hopkins and Sisters Together and Reaching Inc. (STAR) have teamed up to offer Baltimoreans free HIV urine testing from a mobile van. The van will operate five days and evenings per week and patrol areas at high risk for HIV. (2000-03-28)

Placental malaria increases mother-to-child HIV transmission
A study by the Johns Hopkins Bloomberg School of Public Health found that placental malaria infection during pregnancy significantly increases the risk of mother-to-child transmission of HIV. Mother-to-child HIV transmission rates were 40 percent among women with placental malaria compared to 15.4 percent for women without malaria. The researchers believe that interventions to prevent malaria during pregnancy could potentially reduce mother-to-child transmission of HIV. (2003-11-05)

Combination of HIV/malaria increases complications during pregnancy
Women with a combined HIV/malaria infection more frequently experience complications during pregnancy than healthy women. This is revealed in research from Kenya. However, to their surprise the researchers established that HIV-infected mothers with a mild malaria infection less frequently transmit the HIV infection to their children than HIV-infected mothers without malaria. (2002-10-24)

Genome editing method targets AIDS virus
By destroying the regulatory genes of the AIDS virus HIV-1 using the genome editing system CRISPR/Cas9, a Japanese research group has succeeded in blocking the production of HIV-1 by infected cells. (2018-05-18)

Prevalence of undiagnosed HIV infection low among state prison entrants
An analysis indicates that the prevalence of undiagnosed human immunodeficiency virus (HIV) infection among state prison entrants in North Carolina was low, at 0.09 percent, according to a study appearing in the Nov. 27 issue of JAMA. (2013-11-26)

UCSF AIDS expert warns threshold for HIV vaccine set too high
The current objective of most HIV vaccines, the absence of any infection of a human by the AIDS virus, is at the present time not possible according to a pioneer HIV/AIDS researcher at the University of California, San Francisco. (2001-01-18)

Scientists find the invisibility cloak that shields HIV-1 from the immune system
Of the two major types of HIV, only one, HIV-1, typically causes AIDS in infected people who don't receive treatment. A study published by Cell Press Nov. 21 in the journal Immunity reveals how HIV-1 escapes detection by essentially becoming invisible to a patient's immune system, whereas HIV-2 triggers protective immune responses in patients. This understanding of how HIV-1's (2013-11-21)

Study finds HIV-infected men at risk for spreading HIV despite taking HAART
Researchers from Boston University School of Medicine and Fenway Health have found that highly active antiretroviral therapy does not completely suppress HIV in the semen of sexually active HIV-infected men who have sex with men. The findings, which currently appear on-line in AIDS, could indicate a potential transmission risk in MSM, who are highly susceptible to HIV infection. (2012-03-27)

Targeted HIV testing more effective than CDC mass testing proposal
A targeted campaign of testing and counseling aimed at those who are at high risk for HIV would be more effective than the mass patient screening proposed by the Centers for Disease Control and Prevention, according to an analysis by David Holtgrave, Ph.D., an expert on HIV prevention at the Johns Hopkins Bloomberg School of Public Health. Holtgrave's study is the first to examine the cost-effectiveness of the CDC's testing plan. (2007-06-11)
