A solution hiding right under our noses

Viral load monitoring shown to be an effective way to boost compliance in HIV patients 

 

Even when ARVs are available, patient compliance has always been a problem. Some programs go to the extreme of having a nurse supervise every dose, every day. The reason it’s such a big deal is that even missing a few doses gives HIV the chance to adapt to the medication and develop resistance. Treatment options are limited and expensive, especially in developing countries.  

So why are patients putting their own lives at risk by skipping doses?
Sometimes it’s a money issue. Sometimes it’s a lack of knowledge about the drugs and their disease. Sometimes it’s because of the side effects. But in the end, we don’t know what they do when they take the drugs and go home. When their doctors inquire about their compliance, they often just say what the doctor wants to hear. Which makes it difficult to know before it’s too late which patients need extra help to consistently take their ARVs.
  

A recent study from Doctors Without Borders has shown that viral load monitoring may be the solution. A group of HIV patients in Thailand were put on monitoring for the first time. Many of them showed detectable viral loads. Most of these were linked to poor compliance.   

By monitoring viral load, doctors were able to see quite early which patients were not responding well to treatment. With this knowledge they could single them out for counseling early on in their treatment regimen. Moreover, the patients’ viral load could be used as a tool to educate and motivate the patient during counseling.    

Virtually all of the patients who were given extra counseling in this manner saw their viral load drop to undetectable levels indicating better compliance. The few who didn’t were flagged as non-responsive and put on second line treatment. This reduced the chance of drug resistant strains developing and being passed on, and avoided wasting valuable drugs that were no longer effective for those patients. 

In an ideal world, patients would follow their doctor’s instructions to the letter and they’d be honest about everything to do with their treatment. But that’s not the world we live in. In the interest of public health, for both individuals and populations as a whole, we should explore these potential solutions to nagging problems wherever we find them. Especially when it is as easily addressed as this issue is.

Sexual transmission of HIV has been described from men to men, men to women, women to men, and women to women through vaginal, anal, and oral sex. The best way to avoid sexual transmission is abstinence from sex until it is certain that both partners in a monogamous relationship are not HIV-infected. Because the HIV antibody test can take up to six months to turn positive after infection occurs, both partners would need to test negative six months after their last potential exposure to HIV. If abstinence is out of the question, the next best method is the use of latex barriers. This involves placing a condom on the penis as soon as an erection is achieved in order to avoid exposure to pre-ejaculatory and ejaculatory fluids that contain infectious HIV. For oral sex, condoms should be used for fellatio (oral contact with the penis) and latex barriers (dental dams) for cunnilingus (oral contact with the vaginal area). A dental dam is any piece of latex that prevents vaginal secretions from coming in direct contact with the mouth. Although such dams occasionally can be purchased, they are most often created by cutting a square piece of latex from a condom.

HIV is truly a silent but deadly killer. Although it might sound quite redundant anyone who regularly engages in sexual activity must get tested for HIV transmission right away. It can only take weeks to turn into AIDS which unfortunately is almost always a death sentence.

I used your instructions for making a reversible jumper and they were great.I agree with your opinions on men and how they more clean cut.People usually talk about gender when they discuss the metero male, but I like how you link it with a historical context to class and divisions between men.
