This page covers only localized lipodystrophy
that is caused by autoimmune diseases. Other causes include AIDS/HIV or retroviral treatments.

Overview

Lipodystrophy (or lipoatrophy) refers to a loss of fat tissue. It can be localized, partial, or total.
Types of Lipodsytrophies. There are several different types of lipodystrophies and the degree of fat loss may vary from very small depressed areas to near complete absence of adipose tissue. Inherited lipodystrophies are caused by mutations in a gene. Acquired lipodystrophies are caused by medications, autoimmune mechanisms or other unknown mechanisms. Southwestern Medical Center.

Prevalence

PatientCrossroads and Lipodystrophy United Launch Global Registry for Lipodystrophy. No one knows exactly how many people are affected by lipodystrophy worldwide, and clinical endpoints that could gauge the effectiveness of treatments are sparse. PR Web, 03/04/2014.
Localized Lipodystrophy. Because localized lipodystrophy is extremely rare, only a few case series of lipodystrophic syndromes are reported in the literature. Emedicine.

Semicircular Localized Lipodystrophy or Lipoatrophy

Semicircular Localized Lipodystrophy. Lipoatrophy can be a common sequela of panniculitis in patients with connective tissue diseases (eg, systemic lupus erythematosus, subcutaneous morphea, the syndrome of lobular lymphocytic connective tissue panniculitis of Winkelmann and Padilha-Goncalves). Lipoatrophy can be associated with nephritis, hypocomplementemia, scleroderma, Sjögren syndrome, recurrent pyogenic infections, immune thrombocytopenic purpura (ITP), and thyroiditis. Medscape.
Lipoatrophia Semicircularis: a new office disease? 900 cases reported in Belgium. This phenomenon was reported for the first time in three patients in 1974 by Gschwandtner and Munzberger. Since then, there have been some publications, but these relate only to 70-odd patients. Since 1995, we have diagnosed more than 900 cases in our company. Although the cause is still unknown, we believe that electromagnetic fields play an important role in this phenomenon. ESD Journal.

Diagnosis

Lipodystrophy, Progressive: Differential Diagnoses & Workup. Urinalysis, baseline creatinine and blood urea nitrogen studies, as well as urine studies, a CBC count, and other tests are recommended for lipodystrophy. Medscape.

Causes

Causes of Lipodystrophy, other than HIV/Aids and retroviral treatment, include autoimmune diseases, dermatomyositis, diabetes, electromagnetic fields, gluten sensitivity, lupus, panniculitis, scleroderma, Sjogren's, and thyroiditis. ISN.

Treatments for Lipodystrophy

FDA approves lipodystrophy drug metreleptin. Until now, standard treatment for lipodystrophy has consisted of high-dose insulin plus triglyceride- or lipid-lowering medications. Metreleptin curbs the appetite and normalizes the lipodystrophy patient's metabolism, offsetting the metabolic abnormalities common in these patients. Southwestern Medical University. 02/25/2014.
