HIVEarly, aggressive treatment of people who’ve been infected by HIV may be a cost-effective method to battle the disease according to a study which focused on two countries with huge HIV positive populations South Africa and India. The study in the New England Journal of Medicine analyzed the economics of giving antiretroviral drugs to people with HIV before their viral load gets too high.

While researchers have already determined that early treatment has many health benefits, its cost about $23,000 a year according to the US Centers for Disease Control and Prevention has remained a concern for considering widespread early treatment in low and middle income countries. By projecting the treatment costs over time and accounting for the effects of better health and fewer infections, researchers found long-term economic benefits in both countries. ‘In short, early ART is a `triple winner`: HIV-infected patients live healthier lives, their partners are protected from HIV, and the investment is superb,’ said co-author Rochelle Walensky of the Massachusetts General Hospital. ‘This study provides a critical answer to an urgent policy question.’ Also Read - 7 reasons why the #BeefBan is good

Researchers chose to focus on South Africa and India because they had the highest numbers of people with HIV among nine countries studied in a clinical trial known as HIV Prevention Trials Network (HPTN) 052. The trial showed that treatment as prevention dramatically reduced the risks of viral transmission and also substantially cut back the development of infections like tuberculosis in the HIV-infected patients. South Africa and India were also representative, respectively, of the middle and lower income countries where these questions persist over how early to treat people for HIV.

Early ART was defined as therapy initiated when the CD4+ T-cell count ranged from 350 to 550 per cubic millimeter, and delayed ART as therapy initiated when the CD4+ count was below 250 per cubic millimeter. ‘We found that early ART substantially improved the rate of survival of infected patients, greatly decreased the rate of early HIV transmissions, and provided an excellent return on investment,’ said the study.

For the first five years, the results showed that 93 percent of patients receiving early ART would survive, compared with 83 percent of those whose treatment was delayed. Life expectancy for the early-treatment group was longer too — almost 16 years, compared with nearly 14 years for the delayed treatment group. ‘Now that we know that early ART not only improves clinical and prevention outcomes but also is a great investment, we need to redouble international efforts to provide ART to any HIV-infected person who can benefit from it,’ said Walensky.

What are CD4 T cells?

CD4 T cells or CD4+ T helper cells (as they’re properly known) are white blood cells that are a vital part of the human immune system. They are called helper cells because their main purpose is to send signals to other types of immune cells including the CD8 killer cells which then search and destroy the infection or virus. In HIV patients, the CD4 cells level goes down, making the body vulnerable to a wide range of infections that it would be able to fight normally. (Read: Together we can end HIV/AIDS)

HIV causes a progressive reduction in the number of CD4 cells. The count of CD4 cells also forms an important part of diagnosis for HIV treatment. Normal values are anywhere between 500-1200 cells/mm3. Treatment starts when the level falls under 350 cells/mm3. A person is considered to have AIDS when his or her CD4 count falls under 200 cells/mm3. (Read: Testing for HIV)
