Fat redistribution in the setting of protease inhibitor use is increasingly common and is associated with insulin resistance in human immunodeficiency virus (HIV)-infected patients. However, little is known regarding the factors that may contribute to abnormal insulin regulation in this population.
The mechanisms responsible for the deterioration in glucose tolerance associated with protease inhibitor-containing regimens in HIV infection are unclear. Insulin resistance has been implicated as a major factor, but the affected tissues have not been identified. Furthermore, beta-cell function has
BACKGROUND
A novel type of acquired partial lipodystrophy resulting from chronic treatment with HIV-1 protease inhibitor drugs has recently been described.
OBJECTIVE
We studied the clinical and histopathologic features of a series of patients with HIV-1 protease inhibitor-associated lipodystrophy to
OBJECTIVE
To identify metabolic and body composition changes associated with HIV-1 infection in a cross-sectional study of individuals stratified by immunologic status and body mass.
METHODS
Metabolic abnormalities including glucose intolerance and changes in body morphology have recently been
Objectives: Corin is a protease that converts pro-atrial natriuretic peptide (pro-ANP) to ANP. While the involvement of ANP in the cardiovascular regulation is well established, there is increasing evidence that the pregnant uterus produces ANP, which promotes
In 1997, and mainly in 1998 and 1999, a lipodystrophic syndrome with central obesity, peripheral fat loss, hyperlipidemia, hyperglycemia and insulin-resistant-diabetes II, was described as the most frequent manifestation of toxicity of HIV1 virostatic therapy, associated with protease inhibitors
It has been generally assumed that insulin circulates freely in blood. However it can also interact with plasma proteins. Insulin receptors are located in the membrane of target cells and consist of an alpha and beta subunits with a tyrosine kinase cytoplasmic domain. The ectodomain, called soluble
HIV protease inhibitors (PI) are fundamental to combination antiretroviral therapy, which has revolutionized HIV clinical care and produced significant reductions in HIV-associated morbidity and mortality. However, PI administration is frequently associated with severe metabolic impairment,
HIV protease inhibitors are key components of HIV antiretroviral therapies, which are fundamental in the treatment of HIV infection. However, the protease inhibitors are well-known to induce metabolic dysfunction which can in turn escalate the complications of HIV, including HIV associated
The disease mechanisms underlying type 2 diabetes (T2D) remain poorly defined. Here we aimed to explore the pathophysiology of T2D by analyzing gene co-expression networks in human islets. Using partial correlation networks we identified a group of co-expressed genes ('module') including F2RL2 that
A novel lipodystrophy syndrome (characterized by insulin resistance, hypertriglyceridemia, and fat redistribution) has recently been described in human immunodeficiency virus (HIV)-infected patients. However, investigation of the lipodystrophy syndrome has generally been limited to men; and a
Multidrug antiretroviral regimens that include human immunodeficiency virus-1 (HIV-1) protease inhibitors are associated with distinct lipodystrophy, hypertriglyceridemia, hyperinsulinemia, and deposition of visceral abdominal adipose tissue. To determine whether these findings are related to
BACKGROUND
Fatty acid concentrations are increased in patients with HIV and fat redistribution and may contribute to insulin resistance in this population.
OBJECTIVE
We determined the effects of acute inhibition of lipolysis on insulin sensitivity in HIV-infected patients with fat redistribution who
BACKGROUND
Otsuka Long-Evans Tokushima Fatty (OLETF) rat, a model of type 2 diabetes, lacks the expression of cholecystokinin-1 receptor mRNA and exhibits inflammation and degeneration of the pancreas and eventually develops insulinopenic diabetes. Protease inhibitors are known to modulate
Type 1 diabetes mellitus is caused by a lack of insulin that results from the autoimmune destruction of the pancreatic beta-cells. Severe diabetes, if not controlled by periodic insulin injections, can lead to ketoacidosis and death. We have previously shown that sustained low level production of
