08-12-2021-0002 - Lipodystrophy Panniculitis

Lipodystrophy syndromes are a group of genetic or acquired disorders in which the body is unable to produce and maintain healthy fat tissue.[1][2] The medical condition is characterized by abnormal or degenerative conditions of the body's adipose tissue. ("Lipo" is Greek for "fat", and "dystrophy" is Greek for "abnormal or degenerative condition".) A more specific term, lipoatrophy, is used when describing the loss of fat from one area (usually the face). This condition is also characterized by a lack of circulating leptin which may lead to osteosclerosis. The absence of fat tissue is associated with insulin resistance, hypertriglyceridemia, non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome.[3][4]

Panniculitis is a group of diseases whose hallmark is inflammation of subcutaneous adipose tissue (the fatty layer under the skin – panniculus adiposus).[1] Symptoms include tender skin nodules, and systemic signs such as weight loss and fatigue.

Restated, an inflammatory disorder primarily localized in the subcutaneous fat is termed a "panniculitis", a group of disorders that may be challenging both for the clinician and the dermatopathologist.[2]:487 The general term for inflammation of any adipose tissue is steatitis.

Lipopolysaccharides

Lipopolysaccharides (LPS), also known as endotoxins, are large molecules consisting of a lipid and a polysaccharide composed of O-antigen, outer core and inner core joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria. The term lipooligosaccharide ("LOS") is used to refer to a low-molecular-weight form of bacterial lipopolysaccharides.

Today, the term endotoxin is mostly used synonymously with LPS,[1] although there are a few endotoxins that are not related to LPS, such as the so-called delta endotoxin proteins secreted by Bacillus thuringiensis.

Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide

Delta endotoxins (δ-endotoxins) are pore-forming toxins produced by Bacillus thuringiensis species of bacteria. They are useful for their insecticidal action and are the primary toxin produced by Bt corn. During spore formation the bacteria produce crystals of such proteins (hence the name Cry toxins) that are also known as parasporal bodies, next to the endospores; as a result some members are known as a parasporin. The Cyt (cytolytic) toxin group is a group of delta-endotoxins different from the Cry group.

cation-selective channels, which leads to death.[2][1]

A gene mostly found on plasmids,[4] delta-entotoxins sometimes show up in genomes of other species, albeit at a lower proportion than those found in B. thuringiensis.[5] The gene names looks like Cry3Bb, which in this case indicates a Cry toxin of superfamily 3 family B subfamily b.[6]

The rash, which occurs in 20–50% of cases, presents itself on the trunk and is maculopapular, classically.[29]
The most common initial conditions that alert to the presence of AIDS are pneumocystis pneumonia (40%), cachexia in the form of HIV wasting syndrome (20%), and esophageal candidiasis.[28] Other common signs include recurrent respiratory tract infections.[28]
People with AIDS have an increased risk of developing various viral-induced cancers, including Kaposi's sarcoma, Burkitt's lymphoma, primary central nervous system lymphoma, and cervical cancer.[29]

The World Health Organization first proposed a definition for AIDS in 1986.[26] Since then, the WHO classification has been updated and expanded several times, with the most recent version being published in 2007.[26] The WHO system uses the following categories:
Primary HIV infection: May be either asymptomatic or associated with acute retroviral syndrome[26]
Stage I: HIV infection is asymptomatic with a CD4+ T cell count (also known as CD4 count) greater than 500 per microlitre (µl or cubic mm) of blood.[26] May include generalized lymph node enlargement.[26]
Stage II: Mild symptoms, which may include minor mucocutaneous manifestations and recurrent upper respiratory tract infections. A CD4 count of less than 500/µl[26]
Stage III: Advanced symptoms, which may include unexplained chronic diarrhea for longer than a month, severe bacterial infections including tuberculosis of the lung, and a CD4 count of less than 350/µl[26]
Stage IV or AIDS: severe symptoms, which include toxoplasmosis of the brain, candidiasis of the esophagus, trachea, bronchi, or lungs, and Kaposi's sarcoma. A CD4 count of less than 200/µl[26]
Specific adverse events are related to the antiretroviral agent taken.[170] Some relatively common adverse events include: lipodystrophy syndrome, dyslipidemia, and diabetes mellitus, especially with protease inhibitors.[25] Other common symptoms include diarrhea,[170][171] and an increased risk of cardiovascular disease.[172] Newer recommended treatments are associated with fewer adverse effects.[29] Certain medications may be associated with birth defects and therefore may be unsuitable for women hoping to have children.[29]
