Publication Date: October 1, 2016

Diagnosis

Diagnosis of lipodystrophy is based on history, physical examination, body composition, and metabolic status. ( B , I )
701
There are no defined serum leptin levels that establish or rule out the diagnosis of lipodystrophy. ( C , IIa )
701
Confirmatory genetic testing is helpful in suspected familial lipodystrophies. ( A , I )
701
Genetic testing should be considered in at-risk family members. ( C , IIa )
701
Serum complement levels and autoantibodies may support diagnosis of acquired lipodystrophy syndromes. ( B , IIa )
701

Diabetes

Diabetes screening should be performed annually. (C)
701

Dyslipidemia

Triglycerides should be measured at least annually and with occurrence of abdominal pain or xanthomata. (C)
701
Fasting lipid panel (total cholesterol, low density lipoprotein-cholesterol [LDL-C], high density lipoprotein-cholesterol [HDL-C], triglycerides) should be measured at diagnosis and annually after age 10 years. ( C , IIa )
701

Liver Disease

Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) should be measured annually. ( C , IIa )
701
Liver ultrasound should be performed at diagnosis, then as clinically indicated. ( C , IIa )
701
Liver biopsy should be performed as clinically indicated. ( C , IIa )
701

Reproductive Dysfunction

Gonadal steroids, gonadotropins, and pelvic ultrasonography should be performed as clinically indicated. ( C , IIa )
701
Pubertal staging should be performed annually in children. ( C , IIa )
701

Cardiac Disease

Blood pressure should be measured at least annually. ( C , I )
701
Electrocardiogram and echocardiogram should be performed annually in congenital generalized lipodystrophy (CGL) and progeroid disorders, and at diagnosis and as clinically indicated in familial partial lipodystrophy (FPLD) and acquired generalized lipodystrophy (AGL). ( C , IIa )
701
Evaluation for ischemia and rhythm monitoring should be considered in patients with progeroid disorders and FPLD2 with cardiomyopathy. ( C , IIa )
701

Kidney Disease

Urine protein should be measured annually using 24 hour urine collection or spot urine protein to creatinine ratio. ( C , )
701

Treatment

Diet

Most patients should follow diets with balanced macronutrient composition. ( C , IIa )
701
Energy restricted diets improve metabolic abnormalities, and may be appropriate in adults. ( C , I )
701
Very low fat diets should be used in chylomicronemia-induced acute pancreatitis. ( C , I )
701
A dietician should be consulted for specialized dietary needs, especially in infants and young children. Overfeeding should be avoided. ( C , IIa )
701
Medium chain triglyceride (MCT) oil formulas can provide energy and reduce triglycerides in infants. ( C , IIa )
701

Exercise

Patients with lipodystrophy should be encouraged to exercise in the absence of specific contraindications. (C)
701

Metreleptin

In generalized lipodystrophy, metrerleptin (with diet) is a first-line treatment for metabolic and endocrine abnormalities (I-B), and may be considered for prevention of these comorbidities in children. (C, IIb)
701
Metrerleptin may be considered for hypoleptinemic (leptin <4 ng/mL)
patients with partial lipodystrophy and severe metabolic derangements (HbA1c >8% and/or triglycerides >500 mg/dL). (B, IIb)
701

Diabetes

Metformin is a first-line agent for diabetes and insulin resistance. ( C , IIa )
701
Insulin is effective for hyperglycemia. In some patients, concentrated preparations and high-doses may be required. ( C , IIa )
701
Thiazolidinediones may improve metabolic complications in partial lipodystrophy, but should be used only with caution in generalized lipodystrophy. ( B , IIb )
701

Dyslipidemia

Statins should be used concomitantly with lifestyle modification (after consideration of age, reproductive status, and tolerance). (C)
701
Fibrates and/or long-chain omega-3 fatty acids should be used for triglycerides >500 mg/dl, and may be considered for triglycerides >200 mg/dL. (C)
701

Hypertension

Angiotensin converting enzyme (ACE)-inhibitors or angiotensin receptor blockers (ARB) are first-line treatments for hypertension in patients with diabetes. (C)
701

Contraception and Hormone Replacement Therapy

Oral estrogens are contraindicated. ( C , IIa )
701
If contraception is needed, progestin-only or nonhormonal contraceptives should be considered. ( C , IIa )
701
If estrogen replacement is needed, transdermal estrogen should be used. ( C , IIa )
701

Pregnancy

Pregnant patients should receive prenatal care from an obstetrician experienced in managing diabetes, and a physician experienced in managing lipodystrophy. ( C , IIa )
701
Should a patient become pregnant while taking metrerleptin, clinicians may consider continuing metrerleptin if withdrawal would harm the mother and fetus and the patient understands that effects of metrerleptin in pregnancy are unknown (FDA category C) and wishes to continue. ( C , )

Document Objectives

Lipodystrophy syndromes are extremely rare disorders of deficient body fat associated with potentially serious metabolic complications, including diabetes, hypertriglyceridemia, and steatohepatitis. Due to their rarity, most clinicians are not familiar with their diagnosis and management. This practice guideline summarizes the diagnosis and management of lipodystrophy syndromes not associated with HIV or injectable drugs.
