November 29 : With the World Aids Day 2019 just around corner on Dec 1, 2019, we need to understand where we stand in the mission to bring a stop to this health issue. Over the years, many progresses have been made in controlling the disease, and by 1990s, first anti-viral drugs were developed to suppress HIV that was proved to be the underlying cause for AIDS. While the fight against the disease continues with the same fervour, numerous studies are being conducted across the world, which reveal new aspects of AIDS. Here, you get to see the latest research that have been conducted on the subject called HIV- AIDS.

HIV positive patients live longer now but may die from other infections

Researchers from NYU School of Medicine and NYU Long Island School of Medicine studied the autopsy reports of 252 people in the US who died due to AIDS, and found a number of trends about AIDS related deaths. The scientists found that currently people affected by AIDS live longer compared who those who died in 1984 at the age of 36. But by 2010, people who died with AIDS, their age rose to 54. The researchers credit the increase in lifespan to different anti-viral drug therapies developed in the 1990s. The study also found that people with AIDS not only died due to old age but also due to infections like pneumocystis pneumonia or hepatitis C. So HIV positive patients have the increased risk of dying from other infections also like pneumonia or hepatitis C, to name a few.

Deaths caused by HIV infection associated with depression

Boston University School of Medicine made a startling revelation in a new study. The researchers found that many people who died due to HIV infection had moderate symptoms of depression as compared to those without HIV infection. It is reported that 20 to 40 percent people infected with HIV and living in the US, suffer from depression. The study associated depressive disorders as one of the causes for increased death in people with HIV infection. However, some conflicting data also exist.

Boston University School of Medicine compared data of people in the US who face the risk of death with HIV to those who are not HIV positive, and found that these patients suffer from depression. They measured depression in two ways—by diagnosing them clinically and through depression related questionnaire. The researchers then established the association between depression and death among people with HIV-positive.

Wound healing in mucous tissues can prevent AIDS

Another study by the University of Washington School of Medicine in the US found a beneficial development. The scientists revealed that wound that heal in mucous tissues during an infection called Simian Immunodeficiency Virus (SIV), help some species against developing AIDS. Mucous tissues protect our body against germs. The study further revealed that some virus-fighting tactics can help in developing better anti-viral drugs to treat HIV positive people. The biological conditions that take place in the wound healing of mucosal tissues create such a condition inside the body that protects the person from the damage caused by SIV infection. This aspect can help develop new therapies to prevent AIDS.

AIDS-immunocompromised patients vulnerable to bacterial infections

A UT's Department of Ecology and Evolutionary Biology study found that people with AIDS-immunocompromised are more likely to be affected with anti-biotic-resistant bacterial infections. Since the immune systems of these patients are weakened, they are more vulnerable to catch bacterial infections. As a result, they become resistant to any medication or treatment.
