A World Without AIDS
A World Without AIDS: How Far Off?
If you are middle-aged or older, you may remember a world without AIDS. After all, it didn’t become a commonly known or understood disease until it started taking the lives of some famous individuals in the 1980s. Today, it is a worldwide epidemic with more than 35 million HIV-positive individuals across the globe. With we ever see a world without AIDS again? That was the question posed at a convention held this past year.
Researchers and top physicians gathered from around the world to discuss the steps involved in getting rid of HIV and AIDS for good. Hopes are high because of the emergence of a few cases of cured individuals. In fact, the first man ever cured from the disease addressed the audience of doctors and researchers, inspiring them to reach their ultimate goal. However, while we wait for the dream of an HIV free world to come about, what else is being done for those who have the disease and what is being done to reduce transmission?
Antiretroviral treatments exist today that allow people with HIV to live a normal lifespan. Of course, this has led to other previously unknown complications of the disease. Now that HIV no longer quickly advances to AIDS, cutting a person’s life short, doctors are discovering that HIV can cause many secondary problems. One of these complications is a series of neurological problems.
Other issues involve the fact that many HIV-positive people around the world live in poor countries. Some of these countries can’t afford proper screening to identify HIV-positive individuals. Others don’t have the refrigeration needed for various treatments. Additionally, most of these nations can’t afford to provide treatment for people who can’t afford it themselves.
This means that, at least for now, the war on HIV is about preventing its spread. This means education for those in the highest risk categories for becoming infected. It also means developing regular and affordable screening for all. These are some of the goals that major contributors to the cause—such as the Bill and Melinda Gates Foundation—are working towards.
In the meantime, it is important for everyone to follow safe sex practices to avoid contracting HIV. It also involves a willingness to get tested. Finally, it means sticking closely to a treatment regimen if you are infected with the disease. This is what individuals can do to play a role in eliminating HIV and AIDS for good. It is a wonderful goal: to once again see a world without AIDS.

Cardiovascular Disease and HIV: A Leading Cause of Mortality
Careful monitoring of those with HIV can help slow down the progression of the disease and other conditions that may come along too. Links between HIV and other chronic conditions are well-known and documented. Recent trends in regards to cardiovascular disease and HIV, however, have physicians on the lookout for new treatments and approaches, as the number of patients suffering from high cholesterol and hypertension is on the rise. This calls for action and new strategies for helping patients not only maintain heart health, but their overall well-being.
While a connection is not surprising between HIV and cardiovascular disease, researchers have noticed a trend that gives cause for concern. Many HIV-positive patients who present with either high cholesterol or hypertension are receiving treatment. The problem lies in the fact that, of those who are on medications, few are actually showing improvement. Clearly, a more effective approach is needed.
The prospects of gaining control over HIV have vastly improved in recent years. Today, HIV can be controlled, and a patient can lead a relatively healthy life. So, while the main cause of death for someone with HIV is not the virus, the other common causes of HIV related deaths now need to be addressed. Of these, stroke and heart attacks are on the rise. The treatments that are available and in use are generally able to control the conditions. The issue is one of helping patients understand the risks, guidelines, and course of treatment. Educating patients and helping them to stick with the outlined course will help change current trends.
Cardiovascular disease and HIV is a reality. While cardiologists and other specialists can help stem the tide, new treatment options are also needed. In order to have more effective results, medications that are specific to the needs and circumstances of those with HIV will have to be developed.

HIV To Treat HIV: HIV ‘Cut and Paste’
Researchers recently applied the idea of ‘cut and paste’ to something completely different than word processing on their computers: the treatment of HIV. Of course, most of us use ‘cut-and-paste’ on a regular basis, whether for emails, documents, or filling in information. Certainly, it is a function that comes in handy. However, this cutting-edge technique could mean really big changes on the HIV battlefield. What we are talking about is using HIV to treat HIV. Obviously, this is an exciting idea. But, how does this process work? Moreover, how will this be beneficial in HIV treatment?
Within our cells are proteins, which are used to perform a variety of tasks. One of these proteins acts like a pair of scissors. It cuts away at the genome, grabbing and separating bits of information. The cell can then use the information as needed. For scientists, these natural ‘scissors’ can be used to help patch up damaged cells. The damaged cells, specifically those infected with HIV, have genetic bits of information missing. In order to patch up these holes, the ‘scissors’ could cut out patches from the virus and then use this to patch up the damaged cells. In effect, parts of the HIV would be cut away to repair the damage done by the disease. This may sound far-fetched, but recent testing gives reason for optimism.
HIV has been studied for nearly three decades and it may seem ironic to use HIV to treat HIV. However, it is a promising point of attack in the fight against HIV and AIDS, especially as this therapy looks particularly sound in the area of strengthening the immune system. Assisting the body to not only resist attack—but also to fend it off in such a manner—would be a big step in the fight against HIV. Should the cut and paste method prove successful, there may be other infections that could also be treated or prevented using similar methods.

HIV Adaptation: Three Decades On
Ongoing studies of how new treatments are performing against HIV are a mainstay of research. Ideas and theories for new treatments and vaccines are continually being studied and debated. Now, three decades since HIV broke onto the scene in North America, one group decided it was time for an investigation into two different areas: First, to find out just how the virus adapts to humans and, second, to see if the virus has changed since it was first introduced. The idea required extensive research on HIV adaptation and it also involved considerable back tracking. However, the effort paid off.
How HIV responds to current drug therapies has been well documented. However, exactly how HIV adapts to its host, humans, has never before been looked into. Going back nearly thirty years, and retrieving important molecular information on HIV, was a tedious task. Nevertheless, in spite of the challenges, the team found what they needed. Based on these findings, it is clear that HIV has adapted over the last couple of decades to humans. What was the process involved? And, what does it mean for us today?
First, the virus infects the host and begins to multiply. This process does not go unnoticed by the host’s immune system, which then immediately dispatches help. This internal fight helps keep the virus in check. Current drug therapies help too. After years of fighting, the immune system can tire out. As time passes, and the virus becomes accustomed to its host, it also begins to adapt to the onslaught brought on by the immune system. After enough time passes, the invader can become quite adept at evading the immune attacks. This is very bad for the host, who has lost the ability to naturally protect itself from the virus.
HIV adaptation has begun, but at this point, the adaptation has been minor. In fact, these changes are so minimal that researchers are confident that current therapies, and vaccines in development, will still be effective. Knowing that the virus can adapt and change is important, as researchers will remain alert to this and adjust research and strategies accordingly.

HIV and Heart Disease
A recent study, underscoring the link between HIV and heart disease, has provided interesting findings. Heart disease is the number one cause of death in the US, with men having a slightly greater risk of developing the condition than women. However, people who have an even greater risk of developing heart disease are those who are infected with HIV. The link between HIV and heart disease is especially pronounced, in regard to plaque buildup in the arteries and actual heart attacks. Moreover, just like heart disease in the general population, men who are infected with HIV have a higher risk of heart disease than women.
Hundreds of HIV infected men, and a control group not infected with the virus, were studied. Background information was also taken into consideration, such as smoking and lifestyle. Advanced scanning techniques were used to gather images of the participants’ arteries, particularly the coronary arteries. These images were used to determine if plaque or a stenosis had developed. Researchers found that those who were HIV-positive had a higher rate of both of these conditions. When it came to non-calcified plaque, those with HIV showed higher rates and greater build-up. This can be dangerous, as this type of plaque buildup can rupture or break free. When this happens, it can cause a blockage in a vessel or even a heart attack. Those who had later stages of HIV, and who were also taking antiretroviral medications, had the most cases of heart disease as well as the most severe cases.
Exactly why HIV and heart disease present together and so often is not yet known. Researchers fully intend to keep investigating. However, now that it is clear what types of disease manifest themselves in men who test positive for HIV, physicians can keep a close eye on their vascular system in order to catch early signs of heart disease.
