[(13)C]Methionine breath test as a marker for hepatic mitochondrial function in HIV-infected patients.

Metabolic disturbances such as dyslipidemia, lipodystrophy syndrome, visceral obesity, hyperlactatemia, diabetes mellitus, and hepatic steatosis have been recognized as serious complications in long-term antiretroviral-treated HIV-infected patients. The oxidative capacity of liver mitochondria plays a central role in their pathogenesis and can be analyzed using the [(13)C]methionine breath test. We analyzed hepatic mitochondrial function using the [(13)C]methionine breath test in antiretrovirally treated and untreated HIV-infected patients as well as HIV-negative controls.

Increased red cell corpuscular volume and hepatic mitochondrial function in NRTI-treated HIV infected patients.

An increase of the mean corpuscular volume of the red blood cells has been repeatedly described in antiretroviral treated patients. Most commonly macrocytosis was associated with the use of certain nucleoside reverse transcriptase inhibitors. The aim of this study was to analyse if macrocytosis might be a marker of mitochondrial toxicity in antiretrovirally treated HIV-infected patients.

Impaired glucose tolerance in pancreas grafted diabetic patients is due to insulin secretory defects.

Introduction: Pancreas transplantation in diabetic patients can sustain insulin independence for years. The aim of the study was to measure the incidence of an impaired or diabetic glucose tolerance in patients after successful transplantation and analyse insulin resistance and insulin secretion.

Methods: 174 Type 1 diabetic recipients of simultaneous pancreas/kidney (SPK) transplants were investigated early (three months) and 95 patients late (five years) after transplantation using an oral glucose tolerance test combined with an iv arginine load.

The influence of HIV infection and antiretroviral therapy on the mitochondrial membrane potential of peripheral mononuclear cells.

Objectives: Clinical disorders occurring in HIV-infected patients on antiretroviral therapy (ART) have been linked to mitochondrial dysfunction, for example, lactic acidosis and lipodystrophy. Mitochondrial membrane potential (delta psi m) is the most direct measure of the state of energization of the mitochondria. We analysed delta psi m, of peripheral blood mononuclear cells (PBMCs) in HIV-negative, healthy subjects (n=8), HIV-infected, treatment-naive patients (n=30), and HIV-infected patients on ART (n=58).

Recurrent adrenocortical carcinoma after laparoscopic resection.

Background: A 53-year-old man presented with left-sided flank pains to the Gastroenterology department of our clinic in September 2004. A left adrenal mass of 6.5 cm by 7.
