Pharmacologic Measures<br />

Re<strong>com</strong>binant Human Growth Hormone<br />

Treatment with re<strong>com</strong>binant human growth hormone<br />

(rHGH), 3-6 mg/d <strong>for</strong> 12 weeks followed by<br />

maintenance <strong>the</strong>rapy with lower doses <strong>of</strong> 1-2 mg/d, has<br />

been shown to reduce visceral fat with minimal impact<br />

on peripheral fat wasting. However, <strong>the</strong> high cost <strong>of</strong><br />

rHGH, <strong>the</strong> high rate <strong>of</strong> adverse effects (including<br />

insulin resistance), and <strong>the</strong> frequent recurrence <strong>of</strong><br />

morphologic abnormalities once rHGH is discontinued<br />

have resulted in a limited role <strong>for</strong> this treatment.<br />

Insulin-Sensitizing Agents<br />

In diabetic and non-<strong>HIV</strong> lipodystrophy, treatment<br />

with thiazolidinediones may decrease visceral fat,<br />

increase peripheral fat, and improve glycemic control.<br />

Un<strong>for</strong>tunately, studies <strong>of</strong> rosiglitazone as treatment <strong>for</strong><br />

lipoatrophy in <strong>HIV</strong>-infected patients have shown mixed<br />

results. Some small studies have reported improvement<br />

in peripheral fat loss; however, a larger, 48-week<br />

randomized trial <strong>of</strong> rosiglitazone in <strong>HIV</strong>-infected<br />

patients with lipoatrophy found no improvement in fat<br />

mass. There<strong>for</strong>e, rosiglitazone cannot be re<strong>com</strong>mended<br />

currently <strong>for</strong> <strong>the</strong> treatment <strong>of</strong> lipoatrophy.<br />

Met<strong>for</strong>min has been somewhat effective in treating<br />

lipoaccumulation in patients with insulin resistance, but<br />

may cause worsening <strong>of</strong> lipoatrophy. Met<strong>for</strong>min should<br />

not be given to patients with an elevated risk <strong>of</strong> lactic<br />

acidosis.<br />

Studies <strong>of</strong> insulin-sensitizing agents continue.<br />

Plastic and Reconstructive Surgery<br />

Various techniques have been investigated, but generally<br />

have limited applicability and efficacy. These include<br />

liposuction and breast reduction <strong>for</strong> lipoaccumulation,<br />

and cheek implants and autologous fat transfer <strong>for</strong> facial<br />

lipoatrophy. Poly-L-lactic acid (Sculptra, New-Fill) is<br />

approved by <strong>the</strong> U.S. Food and Drug Administration<br />

as a treatment <strong>for</strong> facial lipoatrophy. This injectable<br />

material has shown to good cosmetic results, at least in<br />

<strong>the</strong> short term.<br />

Although plastic surgery can help some people with<br />

lipodystrophy, <strong>the</strong> treatments are expensive, may need<br />

to be repeated, and usually are not covered by private or<br />

public-payer sources. In some cases, <strong>the</strong>y may be only a<br />

temporary solution, because abnormalities may reappear<br />

after treatment.<br />

Patient Education<br />

♦<br />

♦<br />

♦<br />

♦<br />

Instruct patients who are receiving ARV<br />

medications to in<strong>for</strong>m <strong>the</strong>ir health care providers if<br />

<strong>the</strong>y notice changes in <strong>the</strong> shape or appearance <strong>of</strong><br />

<strong>the</strong>ir bodies.<br />

Review <strong>the</strong> importance and benefits <strong>of</strong> ART and<br />

assess adherence to <strong>the</strong> regimen.<br />

For patients with lipoaccumulation, re<strong>com</strong>mend<br />

aerobic and resistance exercise to build muscle and<br />

reduce fat. Assess resources in your area <strong>for</strong> safe<br />

muscle-streng<strong>the</strong>ning possibilities.<br />

If weight reduction is needed, refer to a dietitian <strong>for</strong><br />

consultation. Remind <strong>the</strong> patient that quick weight<br />

loss diets may result in excessive muscle loss.
