Proposed Decision Memo for Dermal injections
for the treatment of facial lipodystrophy
syndrome (FLS) (Jan 2010)
“Dermal injections for facial lipodystrophy
syndrome are only reasonable and necessary
using dermal fillers approved by FDA for this
purpose, and then only in HIV infected
beneficiaries who manifest depression
secondary to the physical stigmata of HIV
treatment. All other indications are
noncovered.”
Buttock Lipoatrophy:
Common Unaddressed Complaint
Visceral Fat Reduction
Potential Interventions for Decreasing
Abdominal Fat (visceral adipose tissue-VAT)
Diet- Lower carb?- No data available in HIV
Exercise- cardiovascular and resistance training- Some pilot
data with good results
Weight reduction- non HIV data
Anti-diabetic drugs: Metformin (Glucophage)- conflicting and
inconclusive data
Testosterone gel- subcutaneous fat loss only
Anabolic steroids- Oxandrin, nandrolone?- limited VAT data
Human Growth Hormone (Serostim)- highly effective. FDA
Human Growth Hormone Releasing Hormone- Tesamorelin-
declined approval due to side effects
Not approved yet- Pending issues. Slow action
Modification or cessation of HAART?- Not effective
Surgery- Liposuction of visceral fat very difficult and risky

Developed to measure bone density
Can measure bone density, non-bone density, and fat density
Standard assessment for limb fat (normal >7 kg-8 kg)
Does not tell if truncal fat is subcutaneous or visceral

• Software and calibration
• Body sections differences

– Quick, subject-friendly
– Low radiation exposure
High Prevalence of Vitamin D
Deficiency in HIV Infection
• Retrospective seasonal
analysis of Vitamin D
deficiency within Swiss
cohort
• Started ARV in: Fall
(n=108); Spring (n=103)
− 75% men; age = 37; White =
87%; CD4+ 227; BMI = 22.9
− ARVs: TDF – 17%;
NNRTIs – 43%; PI -56%
• Conclusions
− Vitamin D deficiency is
common, but seasonal
− Blacks are at increased risk
− NNRTI use a risk factor

What Can You Do to Help NOW?
Follow Nelson’s blog : survivingHIV.blogspot.com for all of the
following action items:
Sign a letter to advocate for the inclusion of HIV as a risk factor
for bone density testing for those under 50 years of age.
Monitor how Medicare will set up reimbursement of product and
labor for lipoatrophy correction. Follow up petitions may be
needed if this process is not done well.
Advocate for interventional therapeutic studies to reverse bone
loss in HIV (vitamin D/calcium, prescription drugs, exercise,
hormones). Letters to private investigators, ACTG?
Monitor how Egrifta’s reimbursement or patient assistance
program is set up if approved for visceral fat reduction.
Advocate for research on the use of permanent facial
lipoatrophy options like Artefill.
What Can You Do to Help NOW?
Advocate for research on the use of leptin to decrease
visceral fat.
Advocate for the FDA to require small sub -studies to
study metabolic and body effects of drugs before approval
(Phase 4 studies take too long or are never done)
Advocate for exercise/diet, vitamin D research to the NIH
and private investigators in your area. Lower glycemic
index diets have not been investigated in HIV. Also, help
create and advocate for wellness programs that include
comprehensive approaches (diet/exercise, smoking
cessation, patient empowerment)
Educate your peers about metabolic issues related to
different HIV medications (lipids, fat gain/loss, bone) to
passify fears of naïve patients
Keep reminding investigators and congress people that
physical changes in HIV are disease or drug related!
What you can do for YOU:
• Manage your lipids by natural ways, with HIV medication
changes and/or lipid lowering medications.
• Avoid Zerit , AZT, and higher doses of Norvir if you can
• Try to minimize sugars and processed carbs to your best
abilities
• Maximize soluble fiber (fruits & vegetables), lean protein and
good fats
• Exercise 3 to 4 times a week for an hour combining
resistance and cardiovascular exercise
• Take a vitamin complex twice a day
• Check your hormones and supplement if needed
• Research your hump liposuction and facial reconstruction
options before making a decision
• Stop smoking if you do. Minimize alcohol to 1-2 drinks a
day max.
