hormone, that he had been injecting himself with a low dose for<br />

about seven years, and that growth hormone was why he looked<br />

lean and youthful.<br />

Bingo, I thought, that’s what I want. I’m a 42-year-old Polish<br />

guy who’s put on a belly through beer and bad habits. I know what<br />

this particular body shape should look like. But when I looked in<br />

the mirror I saw something diff erent. I saw a huge barrel belly, an<br />

oddly fat neck and jowls. Protruding from this mass was skinny,<br />

scrawny arms and legs. I felt like an apple on toothpicks.<br />

I’ve been HIV-positive for more than 20 years. I’ve spent 15 of<br />

those years on HIV meds. Don’t get me wrong, I’m thrilled to be<br />

alive. I’m grateful for the meds, but they left their mark on my body.<br />

Th e physical changes from the meds were undeniable. I wasn’t just<br />

getting older and soft er. Th e shape of my body had changed dramatically<br />

and not in a good way. Aft er speaking with Steve, I decided<br />

to do something about it.<br />

I did what the pharmaceutical commercials tell me: I asked my<br />

doctor if growth hormone was right for me. Oddly, he got a little<br />

nervous. You don’t really have AIDS wasting, he mumbled, adding<br />

that there are a lot of side eff ects. Instead,<br />

he suggested a surgical procedure where<br />

my stomach is permanently clamped off by<br />

a band that’s implanted in the body. Th is<br />

option seemed extreme.<br />

Coincidentally, I heard about an experimental<br />

drug called tesamorelin, which<br />

supercharged your body to kick up its own<br />

natural levels of growth hormone. Soon, I<br />

joined a clinical trial of tesamorelin to treat<br />

HIV-associated belly fat. Just recently, I<br />

completed the year-long trial. Now, I have<br />

the unique opportunity to assess how human growth hormone has<br />

changed my life.<br />

A hangover from the AIDS cocktail<br />

It was around 1996 when the success of the “AIDS cocktail”<br />

made headlines. It was a breakthrough. For the fi rst time, HIV<br />

medicine was good enough to essentially snuff out the virus and<br />

start to save lives. It was a welcomed change of course for a beleaguered<br />

patient community. So it almost seemed inconsequential in<br />

the very beginning when anecdotes of strange body-shape changes<br />

fi rst began to emerge as a side eff ect of the medicine.<br />

Th e AIDS cocktail got its name because it combined three different<br />

classes of HIV drugs.<br />

One class is the protease inhibitors, of which indinavir is a<br />

member. Indinavir is the generic name of the drug and Crixivan is<br />

the brand name. Another class is the nucleoside analogs, of which<br />

zidovudine and stavudine are members. Stavudine’s brand name is<br />

Zerit. Zidovudine’s brand name is Retrovir, but it’s better known<br />

as AZT. It’s also one ingredient in various combination pills by the<br />

names Combivir, Epzicom, and Trizivir.<br />

As body-shape side eff ects emerged among patients taking the<br />

cocktail, the changes sometimes got informally named as AZT butt<br />

or Crix belly. It seemed that the nucleoside analogs were associated<br />

with fat loss in the buttocks, legs, arms, and cheeks. On the other<br />

hand, the protease inhibitors were associated with fat gain in the<br />

stomach, jowls, and neck. Another distressing condition was a disfi<br />

guring accumulation of fat at the base of the neck called “buff alo<br />

hump.”<br />

Over time, the anecdotes could not be ignored. As researchers<br />

examined the issue more closely, they also found unusually high<br />

levels of cholesterol and triglycerides in the blood of patients taking<br />

protease inhibitors. Th e range of conditions baffl ed doctors, but one<br />

thing was clear: the common denominator was fat.<br />

“Fat loss is clearly associated with stavudine and to a lesser<br />

extent, zidovudine,” said Valerianna Amorosa, M.D. She is chief of<br />

Infectious Diseases at the Philadelphia Veterans Hospital in Pennsylvania.<br />

Her clinical practice and research focuses on conditions<br />

related to HIV, hepatitis C, and obesity. As for the cause of buff alo<br />

hump, she said the jury is still out. “We thought it was the protease<br />

inhibitors, but I don’t think it’s that simple any more.”<br />

Th ese days, the trend is to distinguish between weight gain<br />

and weight loss as separate and distinct conditions. Weight loss in<br />

When Steve turned the corner<br />

and I saw him, once again I was<br />

struck by his lean and youthful<br />

appearance.<br />

the butt, legs, arms, and cheeks is called lipoatrophy. Weight gain<br />

around the belly is called excess visceral adipose tissue, which is<br />

abbreviated as VAT. I prefer to use the lowercase vat because it’s<br />

similar to fat, but still diff erent. Too much vat gives your body an<br />

apple shape, with fat growing between internal organs. Gardenvariety<br />

fat tends to distribute itself more evenly and stays just below<br />

the skin where it’s less harmful.<br />

Sometimes, it’s hard to tell the diff erence between fat and vat,<br />

notes Amorosa. Th e commonly used body mass index, also called<br />

BMI, is not a great indicator of the risks associated with being overweight.<br />

Vat is linked to high blood pressure, diabetes, high cholesterol,<br />

and high triglycerides. Th e diff erence between vat and fat is<br />

where the fat lives on the person. “In somebody who has a BMI of<br />

26, but who doesn’t have a big belly, who has a relatively fl at belly,<br />

and has some weight in the trunk or in the bottom, I don’t worry<br />

as much about them.”<br />

High levels of cholesterol and triglycerides or glucose problems<br />

are collectively referred to as metabolic syndrome. A surprising<br />

study in 2007 found the prevalence of metabolic syndrome among<br />

people with HIV is not any higher than that of the general population.<br />

Metabolic syndrome, it seems, has less to do with HIV medicine<br />

and more to do with beer and bad habits.<br />
