Antiretroviral therapy (ART) is frequently associated with metabolic alterations, including insulin resistance and diabetes mellitus. In this pilot study, we evaluated the effect of the PPARgamma activator troglitazone on ART-associated insulin resistance in HIV-infected patients with ART-associated
We previously reported that ubiquitin-specific protease (USP) 2 in macrophages down-regulates genes associated with metabolic diseases, suggesting a putative anti-diabetic role for USP2 in macrophages. In this study, we evaluate this role at both cellular and individual levels. Isolated macrophages
OBJECTIVE
To evaluate and compare effects of 48-week treatment with rosiglitazone and metformin on insulin resistance in patients infected with Human Immunodeficiency Virus (HIV) receiving highly active antiretroviral therapy (HAART), containing a protease inhibitor.
METHODS
Randomized prospective
OBJECTIVE
Lon protease degrades oxidatively damaged proteins in mitochondrial matrix. To examine the relationships between mitochondrial quality control, mitochondrial functions and diabetes, we investigated whether lon protease deficiency influences insulin resistance by affecting mitochondrial
BACKGROUND
HIV protease inhibitors improve the morbidity and mortality of HIV infection, however, this therapy also initiates insulin resistance that is associated with an increasing development of disturbances in glucose and lipid metabolism. Similar to the common insulin resistance syndrome,
Endothelial dysfunction may contribute to increased cardiovascular events among HIV-1-infected patients receiving antiretroviral therapy. The HIV-1 protease inhibitor indinavir causes both vascular dysfunction and insulin resistance, but the relationship between the two disturbances is not
Insulin resistance, hyperglycemia, and type 2 diabetes are among the sequelae of metabolic syndromes that occur in 60-80% of human immunodeficiency virus (HIV)-positive patients treated with HIV-protease inhibitors (PIs). Studies to elucidate the molecular mechanism(s) contributing to these changes,
HIV-associated insulin resistance frequently presents as relative lack of peripheral adipose tissue storage associated with dyslipidemia. This review discusses explanations for the links between acute and subacute abnormalities in glucose metabolism and chronic changes in adipose tissue
BACKGROUND
Protease inhibitor therapy in human immunodeficiency virus (HIV)-infected adults has been associated with onset or aggravation of glucose intolerance. We report a case of a pregnant HIV-infected woman receiving highly active antiretroviral therapy who developed acute onset of severe
Previous pediatric studies have failed to demonstrate a clear association between protease inhibitor (PI) therapy and abnormal glucose homeostasis in HIV-infected children. To define more precisely the impact of PI therapy on glucose homeostasis in this population, we performed the insulin-modified
BACKGROUND
Fasting hyperglycemia has been associated with HIV protease inhibitor (PI) therapy.
OBJECTIVE
To determine whether absolute insulin deficiency or insulin resistance with relative insulin deficiency and an elevated body mass index (BMI) contribute to HIV PI-associated
Protease inhibitor (PI) therapy for the treatment of patients infected with human immunodeficiency virus is frequently associated with insulin resistance and diabetic complications. These adverse effects of PI treatment result to a large extent from their inhibition of insulin-stimulated glucose
OBJECTIVE
To test agent and cell-type specificity in insulin resistance induced by prolonged exposure to HIV protease inhibitors (HPI), and to assess its relation to the direct, short-term inhibition of insulin-stimulated glucose uptake.
METHODS
Following prolonged (18 h) and short (5-10 min)
HIV protease inhibitors (HPIs) are potent antiretroviral agents clinically used in the management of HIV infection. Recently, HPI therapy has been linked to the development of a metabolic syndrome in which adipocyte insulin resistance appears to play a major role. In this study, we assessed the
BACKGROUND
The use of protease inhibitors in the treatment of HIV-1 infection is associated with the new onset of diabetes mellitus, hyperlipidaemia and lipodystrophy. It is unclear whether these findings are coincidental or whether they reflect a causative effect of protease
