The document provides information on lipoatrophy, a condition characterized by loss of fat under the skin, which can occur in some HIV-positive patients taking antiretroviral therapy. It discusses that some antiretroviral drugs are more strongly associated with lipoatrophy than others, with nucleoside reverse transcriptase inhibitors like stavudine and zidovudine posing higher risks. Switching patients to different drug regimens can help reduce or reverse fat loss in some cases. The document also seeks to educate healthcare providers on lipoatrophy so they can better communicate with patients about diagnosis and treatment options.

The What, the Why, and the How
of Lipoatrophy in HIV CEU Information
8. In The What, The Why, and The How
of Lipoatrophy in HIV slide set, we’ll:
• Describe what lipoatrophy is, and what it‘s not
• Discuss current studies about lipoatrophy in HIV
• Provide information on surgical and non-surgical treatment of
lipoatrophy
9. We’ll also:
• Explore the myths (and realities) of fat loss
• Provide tips for better communication with patients
• Point out the differences between lipoatrophy and AIDS wasting
• Review types of body fat changes (lipodystrophy)
10. Antiretroviral therapy extends life
Percentage of persons surviving through June 2005, by years after
acquired immunodeficiency syndrome (AIDS) diagnosis cohorts
during 1981-2003 and by year of diagnosis--United States
[Centers for Disease Control and Prevention 2005]
12. Lipodystrophy (lipo-diss-troh-fee)
• Lipo means fat, and the word dystrophy means abnormal
looking
• A general ―umbrella‖ term that is used to describe various
changes that occur in the body in how it uses and distributes
FAT
• The conditions that fall under the lipodystrophy umbrella can be
very different in cause and effect
14. Lipoatrophy (lip-oh-aah-troh-fee)
• Lipo means fat and atrophy means shrinkage
lipoatrophy = ―fat loss‖
• Is often seen in people living with HIV who take
anti-HIV drugs
• Also can occur in those with HIV who have never taken
anti-HIV drugs, and in other diseases such as diabetes
or in rare genetic diseases

17. Lipoatrophy occurs gradually
At first:
• Legs, arms and face appear thinner
• People may like that their cheekbones are starting to stand
out a little and that their body looks a little more ―cut‖
Then, as fat loss continues:
• Skin loosens, becomes thinner
• Bones, veins, tendons and muscles become much easier to see

21. How many people have lipo?
• Reports vary from as little as 8% to 84%
– Largest studies suggest 40% to 65%
– The estimates are affected by how long people have been
on HIV treatment and what type of HIV medication
• Reported less often in women—10% to 35%, and may be low
due to underreporting.

24. What are mitochondria?
• Mitochondria are the cell‘s
‗energy factories‘ where sugar
and fat are burned to turn it into
energy
• If mitochondria are damaged, fat
cells start to shrink and then die

ACTG 5142: A study that compared three anti-HIV drug combos
– NNRTI + 2 NRTIs [Sustiva (efavirenz) + 2 NRTIs]
– Protease inhibitor + 2 NRTIs [Kaletra (lopinavir/rt)+ 2 NRTIs]
– NNRTI + PI [Sustiva + Kaletra (no NRTIs)]
Results:
– Sustiva + NRTIs is two times more likely to cause fat loss
(lipoatrophy) than Kaletra + NRTIs
– Sustiva + Kaletra had lowest rate of fat loss
• 8% at 96 weeks compared to 36% in Sustiva + NRTIs arm
vs 18% in Kaletra + NRTIs arm
– Patients using Viread (tenofovir, TDF) had less fat loss
compared to other NRTIs used—Retrovir (AZT) or Zerit (d4T)

[Moyle, G. et al. The Rave Study. ICAAC, 2005]
31. SMART Study
People experiencing fat loss ask, ―SHOULD I STOP MY PILLS?‖
The short answer is: ―NO!‖
The long answer includes information about the SMART Study:
• A huge study (5,472 people), SMART compared continuous anti-
HIV treatment against intermittent (―on and off‖) treatment to see
if side effects could be lessened and the virus still controlled or
suppressed
• The study was stopped because of more AIDS and more deaths
in the intermittent group; risk of heart disease was also greater in
this group
[Phillips A, Carr A, Neuhaus J, et al. CROI 2007 Abs 41. ]
32. Take-home messages
• Daily, continuous anti-HIV treatment is better for
the heart AND for controlling HIV than ―on and off‖
anti-HIV treatment
• Some anti-HIV drugs cause less fat loss than others
• It‘s better to avoid fat loss than to try to get fat back once it‘s
gone
34. Facial lipoatrophy grading
Progression of facial fat loss
–Grade 1: Obvious only to patient
–Grade 2: Others start to notice
–Grade 3: Everyone notices
–Grade 4: Mirrors become the enemy
[Grinspoon, Carr. N Engl J Med 2005; 352:48.]
[James J et al. Dermatol Surg 2002;11:979–986.]
36. Tools to measure fat loss
• Different amounts x-ray energy are
absorbed by fat, muscle and bone
• Exposes patient to only 20% of the
radiation that a regular chest x-ray
uses
• Very accurate; recommended at
change of HIV therapy, especially
when fat loss is reason for switch
• Covered by most insurance
DEXA (Dual-Energy X-ray
Absorptiometry)
[Levine J et al.[Levine J et al. J Appl PhysiolJ Appl Physiol 2000;88:452.]2000;88:452.]
[Kamel E. et al[Kamel E. et al Obes ResObes Res 2000;8:36.]2000;8:36.]
[Mitsiopouools[Mitsiopouools J Appl PhysiolJ Appl Physiol 1998;85:115.]1998;85:115.]
37. Tools to measure fat loss (2)
• Uses x-rays to look at slices of the body. Expensive, more
commonly used to measure fat gain, exposes patient to
radiation, 1 per year allowed.

38. Tools to measure fat loss (3)
Skin-fold test
A metal tool is used to
―pinch‖ body tissue in
several places. The
measurements are
compared to standards.
Requires a skilled
technician.
MRI (Magnetic Resonance Imaging)
uses a magnetic field to create an image of
the body showing the location and amount of
fat; very expensive
[Levine J et al.[Levine J et al. J Appl PhysiolJ Appl Physiol 2000;88:452.]2000;88:452.]
[Kamel E. et al[Kamel E. et al Obes ResObes Res 2000;8:36.]2000;8:36.]
[Mitsiopouools[Mitsiopouools J Appl PhysiolJ Appl Physiol 1998;85:115.]1998;85:115.]
39. Tools to measure fat loss (4)
Waist-to-hip ratio uses a
mathematical formula to
measure fat:
• May not hold true for
people with HIV who have
gained fat around the waist
• Gender and how much a
person is overweight has
to be brought into the
equation
40. Take-home messages
DEXA is the best test to get an all-around look at fat loss:
• Reliable and fairly easy to get for most people in the US
• Can measure facial fat loss
• Also measures bone density
42. Fat loss and stigma
Fat loss may:
• Be an unintentional signal to others of HIV-positive status
• Decrease a person‘s confidence and social involvement
• Cause a person to avoid or stop needed anti-HIV medication
because of fear of stigma
[O‘Donovan CA, et al.. 7th International Workshop on Adverse Drug Reactions and Lipodystrophy in
HIV. November 13-16, 2005, Dublin, Ireland. Abs 34. Antiviral Therapy 2005; 10:L24.]
43. HIV-related stigma
The general public still fears and judges people living with HIV, and
such feelings can:
• Cause negative feelings toward persons living with HIV/AIDS, their
families and friends
• Make it easy to justify treating those of different gender, sexuality,
and race badly
[Rintamaki L, Davis T, et al. AIDS Patient Care and STDs. 2006, 20(5): 359-368. doi:10.1089/apc.2006.20.359.]
44. Management options
1. Non-surgical options
2. Surgical options
Two main types of management options have been studied in
clinical trials:
46. Can’t we just take another pill?
Agents studied to try
to increase fat
Results
Rosiglitazone Minimal effect and may hurt heart by raising
cholesterol and triglycerides
Pioglitazone In one study pioglitazone raised limb fat but only
in those NOT taking Zerit (stavudine, d4T)
Pravastatin Fat gains shown but the study was small, and of
short (12W) duration
Uridine NucleoMaxx® is EXPENSIVE! Fat gains shown but
the study was small, and of short (12W) duration
Human Growth Hormone Makes fat loss worse
[Slam L, et al. 13th CROI 151LB.]
[Cavalcanti RB, et al. and Grinspoon S et al. J Infect Dis.--both Published online, ahead of print (May 2, 2007).]
[Mallon PWG et al. Antiviral Therapy 10: L5, 2005.]
[Macallan, DC, et al.. 46th ICAAC. Abs H-1897.]
47. Surgical options - facial restoration
• There are currently several treatments to restore the
appearance of the face
• These products are facial fillers that correct the symptoms of
lipoatrophy
• They do not correct the cause of the problem: fat cell destruction

50. Before After
• The hope is that
the results will
be visible and
safe
• There is risk
of infection
and unwanted
results with all
facial fillers
51. Reconstructive therapy
recommendations: DHHS 2006
Adverse effects Fat maldistribution
Causative ARVs PIs; d4T
Onset /clinical
manifestations
Onset: Gradual: months after initiation of therapy
Symptoms:
• Lipoatrophy: peripheral fat loss manifested as facial thinning,
thinning or extremities and buttocks (d4T)
• Increase in abdominal girth, breast size, and dorsocervical fat
pad (buffalo hump)
Estimated frequency High: exact frequency uncertain; increases with duration on
offending agent
Risk factors Lipoatrophy: low baseline body mass index
Prevention/Monitoring None to date
Management • Switching to other agents may slow or halt progression;
however, may not reverse effects
• Injectable poly-L-lactic acid for treatment of facial lipoatrophy
[DHHS Panel on Antiretroviral Guidelines for Adults and Adolescents 2006]
52. Butt-enhancer pants
• Padded shorts are designed to
– Make sitting less painful
– Fill out clothing and give a more ―normal‖ rear view
53. Butt pants add back
• Male and female versions available
• Cost $35-$40
54. What have we learned?
• It is better to avoid fat loss in the first place with careful anti-HIV
drug selection than to try to fix it after it‘s gone: The NRTI, Zerit
(stavudine, d4T)—and to a lesser extent, Retrovir (zidovudine,
AZT)—are to be avoided, if possible.
• Some anti-HIV drugs are more fat-loss friendly than others: Viread
(tenofovir), Ziagen (abacavir), Kaletra (lopinavir/ritonavir) have all
shown little—or significantly less—fat loss than the drugs they were
compared to in recent studies
• Switching Zerit or Retrovir to fat-loss friendly NRTIs can help
restore some fat, but a return to ―normal‖ isn‘t happening
• Use DEXA scan to assess for fat loss (or fat gain) early on and later
in therapy. It‘s good to have results from different time periods to
compare
• There are patient assistance programs available to help with cost of
two facial filler treatments
55. Tips to assist patients
• Always ask healthcare
providers to do his/her
homework (you do some
too!) before choosing
various therapies
• Be sure to continue to find
ways to obtain up-to-date
information and resources
related to fat loss, and share
the info with others
56. Patient–provider communication
• Taking anti-HIV therapy when and how it is supposed to be
taken is a key part of HIV treatment success
• Healthcare providers
should address all stigma-
related issues (including fat
loss) when counseling
patients before antiretroviral
treatment is started
57. Patient–provider communication (2)
• Counsel patients about when to start or change
anti-HIV treatments
• Listen to patients‘ concerns and assist them in finding the
anti-HIV medicines that best fit their needs
[Rintamaki L, Davis T, et al. AIDS PATIENT CARE and STDs, Volume 20, Number 5, 2006]
