Ferreira-Marques Lipoatrophy

Ferreira-Marques lipoatrophy is a medical condition characterized by the loss of subcutaneous fat in a symmetrical manner, affecting the face, limbs, and trunk. This condition is also known as progressive symmetrical lipoatrophy (PSL) or partial lipodystrophy.

Lipoatrophy is a general term used to describe the loss of subcutaneous fat, which is the layer of fat beneath the skin. This condition can be caused by a variety of factors, including genetics, disease, and medications. Ferreira-Marques lipoatrophy is a specific form of lipoatrophy that is believed to be caused by an autoimmune process, where the body attacks and destroys its own fat cells.

Types of Ferreira-Marques Lipoatrophy:

1. Familial Progressive Symmetrical Lipoatrophy (FPL): This is a rare, inherited form of Ferreira-Marques lipoatrophy that is caused by a genetic mutation. FPL typically presents in childhood or early adulthood and progresses slowly over time.
2. Acquired Progressive Symmetrical Lipoatrophy (APSL): This form of Ferreira-Marques lipoatrophy is not inherited and is caused by an autoimmune process. APSL typically presents in adulthood and progresses rapidly.
3. Drug-Induced Progressive Symmetrical Lipoatrophy (DIPL): This form of Ferreira-Marques lipoatrophy is caused by certain medications, such as thiazolidinediones (TZDs) and protease inhibitors (PIs). DIPL typically presents in adulthood and can progress rapidly or slowly, depending on the individual.

Causes

The exact cause of Ferreira-Marques lipoatrophy is still not well understood, but there are several factors that are thought to contribute to its development. Some of the most common causes of Ferreira-Marques lipoatrophy include:

1. Genetic factors: There may be a genetic component to Ferreira-Marques lipoatrophy, as some families have a higher incidence of the condition. However, the exact genes involved have not been identified.
2. Infections: Certain infections, such as human immunodeficiency virus (HIV) and hepatitis C, have been associated with the development of lipoatrophy.
3. Medications: Certain medications, such as antiretroviral drugs used to treat HIV, insulin, and growth hormone, have been linked to the development of lipoatrophy.
4. Metabolic disorders: Certain metabolic disorders, such as diabetes, can lead to the development of lipoatrophy.
5. Nutritional deficiencies: Deficiencies in essential nutrients, such as vitamins B1, B2, and B6, can lead to the development of lipoatrophy.
6. Autoimmune disorders: Autoimmune disorders, such as lupus and rheumatoid arthritis, have been linked to the development of lipoatrophy.
7. Trauma: Physical trauma, such as burns, can lead to the loss of subcutaneous fat tissue.
8. Radiation therapy: Radiation therapy used to treat cancer can lead to the loss of subcutaneous fat tissue.
9. Toxins: Exposure to certain toxins, such as alcohol and drugs, can lead to the development of lipoatrophy.
10. Hormonal imbalances: Hormonal imbalances, such as hypothyroidism and hyperadrenocorticism, can lead to the development of lipoatrophy.
11. Lipodystrophies: Lipodystrophies are a group of disorders characterized by the abnormal distribution of body fat. Some forms of lipodystrophy can lead to the development of lipoatrophy.
12. Lipid metabolism disorders: Disorders of lipid metabolism, such as hyperlipidemia and hypertriglyceridemia, can lead to the development of lipoatrophy.
13. Inflammatory conditions: Inflammatory conditions, such as Crohn’s disease and ulcerative colitis, have been linked to the development of lipoatrophy.
14. Malnutrition: Malnutrition, including caloric and protein deficiencies, can lead to the development of lipoatrophy.
15. Aging: The natural aging process can lead to the loss of subcutaneous fat tissue.
16. Steroid use: The use of steroids, either for medical reasons or for performance enhancement, can lead to the development of lipoatrophy.
17. Stress: Chronic stress has been linked to the development of lipoatrophy.
18. Sleep deprivation: Sleep deprivation has been linked to changes in hormone levels and metabolism that can lead to the development of lipoatrophy.
19. Poor circulation: Poor circulation, particularly in the extremities, can lead to the development of lipoatrophy.
20. Sedentary lifestyle: A sedentary lifestyle and lack of physical activity can lead to the development of lipoatrophy.

Diagnosis

The diagnosis of this condition is often challenging and requires a comprehensive evaluation that includes a thorough medical history, physical examination, and a series of laboratory and imaging tests. Here is a list of diagnostic and test procedures that can be used to diagnose Ferreira–Marques lipoatrophia:

1. Clinical examination: A physical examination is performed to evaluate the presence and extent of fat loss, as well as to identify any associated physical abnormalities.
2. Family history: A detailed family history is taken to determine if there is a genetic component to the condition.
3. Blood tests: A series of blood tests are performed to assess the patient’s overall health and to identify any underlying medical conditions that may be contributing to the fat loss.
4. Complete blood count (CBC): This test measures the number of red and white blood cells and platelets in the blood.
