Anabolic steroids help people with HIV put on weight and muscle mass

People with HIV who are treated with anabolic steroids to prevent AIDS wasting may realize modest gains in weight and muscle mass, a new review shows.
The review covered 13 studies of adults age 24 to 42 with HIV, 294 of whom received anabolic steroids for at least six weeks and 238 of whom received placebo. The average weight increase in those taking anabolic steroids was nearly three pounds.

“The magnitude of weight gain observed may be considered clinically relevant,” said lead author Karen Johns. “One hopes there would be greater weight gain with the long-term use of anabolic steroids; however, this has not been proven to date in clinical trials.”

AIDS wasting, which leads to significant weight loss in people with HIV, causes severe loss of weight and muscle and can lead to muscle weakness, organ failure and shortened lifespan. Researchers have long sought to reverse this common, destructive effect of HIV with mixed success.

The wasting stems from loss of the body’s ability to grow muscle and from low levels of testosterone.

Anabolic steroids are synthetic substances similar to the male sex hormone testosterone that promote growth of skeletal muscle and the development of male sexual characteristics.

Although most recently in the news for their misuse by professional athletes, anabolic steroids have legitimate medical application for men with low testosterone and people with certain types of anemia. Two anabolic steroids available in the United States, nandrolone decanoate and oxandrolone, have been used to help increase weight and muscle mass in small studies of people with wasting.

Conversely, anabolic steroid use has been associated with increased rates of HIV in those who share needles or use nonsterile needles when they inject steroids.

In the review studies, anabolic steroids were administered to patients either orally or by injection. The main side effects were mild and included abnormal liver function tests; acne; mild increase in body hair; breast tenderness; increased libido, aggressiveness and irritability; and mood swings — all common side effect of anabolic steroid use.

“The risks and side effects of taking anabolic steroids long-term are certainly of concern,” Johns said. “We were unable to assess these risks in our review due to the short duration of treatment in the studies.”

Wayne Dodge, M.D., the HIV/AIDS program director at the Group Health Cooperative in Seattle, suggests that clinicians should obtain blood testosterone levels, “if an HIV-infected individual has had significant weight loss, significant fatigue or muscle wasting, and particularly if associated with a significant decrease in libido and erections. If [testosterone] is in the low or low-normal range then a trial of [steroids] could be tried. The individual and the clinician should decide what result would constitute a successful trial: weight gain of 15 pounds, a 30 percent improvement in sense of well-being [or] a successful erection once a week.”

The reviews authors conclude that further studies are needed to determine if increase in weight leads to improved physical functioning and quality of life, and ultimately increased survival, as well as the potential for serious side effects, especially with prolonged use.

AIDS & HIV: Treatment & Prevention

While 1.1 million Americans currently live with HIV/AIDS, the incurable virus is no longer a quick death sentence and has become a chronic, manageable condition.

Symptoms & Complications

When a person is first exposed to HIV, they may show no symptoms for several months or longer. Typically, however, they experience a flu-like illness that includes fever, chills, headache, fatigue, muscle aches and enlarged lymph nodes in the neck and groin areas. This early illness is often followed by a “latency” phase where the virus is less active and no symptoms are present, according to the U.S. Department of Health and Human Services. This latent period can last up to a decade or more.

As HIV progresses into full-blown AIDS, it severely damages the immune system, causing a wide variety of symptoms such as:

• Rapid weight loss or “wasting”
• Extreme fatigue
• Recurring fevers and night sweats
• Prolonged gland swelling
• Prolonged diarrhea
• Sores in the mouth, genitals or anus
• Pneumonia
• Skin blotches
• Depression, memory loss and other neurological effects

According to the U.S. Centers for Disease Control (CDC), untreated HIV is also linked to serious conditions such as cancer, liver disease, cardiovascular disease and kidney disease. 

Diagnosis & Tests

Since HIV/AIDS can set off so many other illnesses, it may be difficult initially to pinpoint the source. Typically, however, these illnesses appear in clusters over a short period of time, cluing patients and doctors into the presence of the virus. According to NIAID, two types of blood tests can confirm HIV/AIDS infection:

• ELISA, or enzyme-linked immunosorbent assay, which detects disease-fighting proteins called antibodies that are specific to HIV; and

• Western blot, which detects antibodies that bind to specific HIV proteins

After someone is first infected it may take weeks or months for the immune system to produce enough detectable antibodies in an HIV blood test. Ironically, an infected person’s viral load may be very high during this time, making the infection exceptionally contagious. Because of this, the CDC recommends routine HIV testing for all adolescents, adults and pregnant women, and advises that everyone between the ages of 13 and 64 should be tested at least once.

Conventional HIV/AIDS tests are sent to a laboratory for analysis and may take a week or more for results. A rapid HIV test is also available that offers results in about 20 minutes, but positive results from either type of test are confirmed with a second test.

Prevention

More than 56,000 Americans become infected with HIV each year, according to the U.S. Department of Health and Human Services. While some AIDS patients have been infected through blood transfusions during medical procedures, preventing infection usually depends on avoiding risky habits or behaviors that lead to exposure to the virus, which can be transmitted through blood, bodily fluids such as semen and infected needles.

Prevention measures include:

• Knowing yours and your partners’ HIV status
• Using latex condoms correctly during every sexual encounter, whether gay or straight
• Limiting the number of sexual partners
• Abstaining from injectable drug use
• Seeking medical treatment immediately after suspected HIV exposure, since medications can sometimes prevent infection if started early

It’s just as important to know the ways HIV cannot be spread, such as by:

• Saliva, tears or sweat
• Water or air
• Casual contact such as closed-mouth kissing or shaking hands
• Insects, including mosquitoes

Early HIV Treatment a Win-Win

A cost-effective way to help patients stay healthy and prevent virus transmission. Providing early antiretroviral drug treatment for recently infected HIV patients and their uninfected sexual partners is a cost-effective way to help patients stay healthy and prevent transmission of HIV, a new study finds.

The study, looked at HIV patients in India and South Africa. Some of the patients received early antiretroviral therapy while the start of treatment was delayed for other patients. HIV is the virus that causes AIDS.

During the first five years of the study, 93 % of those who received early antiretroviral therapy survived, compared with 83 % of those whose treatment was delayed. Life expectancy was nearly 16 years for those in the early treatment group, compared with nearly 14 years for those in the delayed treatment group.

During the first five years, the potential costs of infections - particularly tuberculosis - prevented by early treatment of HIV patients in South Africa outweighed the costs of antiretroviral therapy drugs, suggesting that the early treatment strategy would reduce overall costs.

This was not the case in India, where the costs of treating HIV-related infections are less. Even so, early antiretroviral therapy in India was projected to be cost-effective according to established standards, the researchers said.

They also found that across patients' lifetimes, early antiretroviral therapy was very cost-effective in both countries. While most of the benefits of early treatment were seen in the HIV-infected patients -- fewer illnesses and deaths -- there were also added health care and economic cost savings from reducing HIV transmission, according to the study.

"By demonstrating that early HIV therapy not only has long-term clinical benefits to individuals but also provides excellent economic value in both low- and middle-income countries, this study provides a critical answer to an urgent policy question," study corresponding author Dr. Rochelle Walensky, of the Massachusetts General Hospital Division of Infectious Disease. "HIV-infected patients live healthier lives, their partners are protected from HIV, and the investment is superb," she added.

Walensky, a professor of Medicine at Harvard Medical School, said the findings point to a need to "redouble international efforts" to provide early antiretroviral therapy to any HIV-infected person who can benefit from it. Her colleague, Dr. Kenneth Freedberg, director of the Medical Practice Evaluation Center at Massachusetts General, agreed.

"Some people have questioned whether providing early [antiretroviral therapy] to all who need it would be feasible in resource-limited countries," he said in the news release. "We've shown that in countries like South Africa, where it actually saves money in the short-term, the answer is 'yes.' We believe that continued international public and private partnerships can make this true in other countries as well."

Freedberg said such an investment could bring about dramatic decreases in infections and illness that could save millions of lives over the next decade.

Multivitamins May Help Fight HIV Progression

But supplements tested only on those who hadn't started medications

New research from Africa suggests that basic multivitamin and selenium supplements might greatly lower the risk that untreated people with the AIDS virus will get sicker over a two-year period.

It's not clear how patients who take the vitamins and mineral might fare over longer periods. And the impact of the study in the United States will be limited because many Americans diagnosed with HIV, the virus that causes AIDS, immediately begin treatment with powerful medications known as anti-retroviral drugs. Those in the African study hadn't yet begun taking drugs to keep the virus at bay.

Still, "it is incredibly useful to find new strategies to delay the progression of HIV disease," said Dr. Jared Baeten, an associate professor of global health at the University of Washington in Seattle who's familiar with the findings. "Not every HIV-infected person is immediately willing, or able, to initiate anti-retroviral therapy. Inexpensive, proven treatments ahead of starting anti-retroviral therapy can fill an important role."

At issue: Do HIV-infected people benefit from nutritional supplements? Previous research has suggested that even well-fed people infected with HIV may not properly process nutrients in food, said study author Marianna Baum, a professor of dietetics and nutrition at Florida International University's Stempel School of Public Health.

The researchers wondered whether the immune system would get a boost if patients who hadn't yet begun anti-retroviral treatment took nutritional supplements. No study had looked at this before, Baum noted.

For the study the researchers divided nearly 900 HIV-infected patients in the African country of Botswana into several groups. Some took a placebo, a sugar pill with no active ingredients. Others took a multivitamin including B, C and E vitamins. Another group took the multivitamin along with supplements of the mineral selenium, and still others took only selenium.

None of the treatments had a noticeable effect except the combination of multivitamin and selenium. After adjusting their statistics so they wouldn't be thrown off by various factors, the researchers reported that those who took the combination were about half as likely to show signs over two years that their infection had progressed toward AIDS as those who took the placebo.

Overall, the risk that the disease would progress over the two years of the study was fairly low: 32 of the 217 who took the placebo suffered progression of the disease, she said, compared to 17 of the 220 who took the vitamin/mineral combination.

Baum didn't have information about the costs of the supplements, but she said they are low. In the United States, supplements that contain many vitamins and minerals can cost just pennies a day.

The supplements appeared to have no side effects, said Baum, who recommends that people newly diagnosed with HIV begin taking multivitamins. They seem to boost the immune system, she said. The selenium supplements, in particular, may provide enough of the mineral that the virus isn't able to hog it, she said.

Baeten cautioned that not just any multivitamin will do. "The results of this study appear to illustrate that it is not just any supplement," he said.

"Only the combination of vitamins plus selenium was effective," Baeten said. "For U.S. patients, this latter point is relevant, as there's a huge variety of supplements available. I would suggest talking with a doctor before taking any supplements."

He added that the study doesn't detract from the crucial importance of anti-retroviral drug treatment.

Researchers next want to see if the supplements help patients already taking anti-retroviral medications, study author Baum said.
