Treatment of HIV-Associated Dyslipidemia: A Role for Omega-3 Fatty Acids
July 1st 2007Both HIV and its treatment, particularly protease inhibitors, can cause dyslipidemia similar to that seen with the metabolic syndrome. The most notable effects are elevated triglyceride levels and decreased high-density lipoprotein cholesterol levels, with or without elevated low-density lipoprotein cholesterol (LDL-C) levels.
Editorial Comment: Fish Oil to Keep the Cardiologist Away?
July 1st 2007Elevated fasting triglyceride levels and low levels of high-density lipoprotein cholesterol (HDL-C) are the hallmarks of HIV-associated dyslipidemia. Despite the perception of many HIV-infected patients and their clinicians, low-density lipoprotein cholesterol (LDL-C) levels among persons infected with HIV-even those receiving antiretroviral therapy––tend to be lower than those in uninfected controls.1,2 During antiretroviral therapy, increases in all lipid parameters are common; however, it is dramatic rises in triglyceride levels that for a number of reasons can be of the most concern.
Prejudice Comes in All Varieties!
July 1st 2007For many of us, the term "prejudice" translates into racism and then into the range of negative, stereotyped assumptions about others based on no more than externally observable features such as skin color or eye shape. We further translate this into discrimination and the full negative history of treating those whom we observe to be racially different.
AIDS Rises Sharply in African Officials, Flash-Heat Inactivation of HIV in Breast Milk

Using corticosteroids to prevent postextubation laryngeal edema
July 1st 2007The effectiveness of corticosteroids in the prevention of postextubation laryngeal edema is controversial, but a recent study conducted in France indicates that the administration of methylprednisolone before a planned extubation does, in fact, reduce the incidence of laryngeal edema and reintubation.
Using galactomannan ELISA to detect invasive aspergillosis
July 1st 2007The development of an enzyme-linked immunosorbent assay (ELISA) that detects the glycoprotein galactomannan represents an important advance in the diagnosis of invasive aspergillosis. Foy and associates found evidence that the galactomannan ELISA is a highly specific diagnostic tool when used to screen patients who are undergoing hematopoietic stem cell transplantation (HSCT).
Hypertensive Woman With Labile Blood Pressure
July 1st 2007At a routine blood pressure check, a 63-year-old woman has 2 readings of 165/100 mm Hg. The patient has had essential hypertension since age 41 years. For more than a decade, it was easily controlled with a b-blocker; however, in recent years, her blood pressure has been more variable, with occasional readings of higher than 150/90 mm Hg.
Lipoprotein(a): A New Treatment Target?
July 1st 2007Lp(a) is a fascinating variant of low-density lipoprotein (LDL). It is basically an LDL molecule that has been modified by the covalent addition of apoprotein(a). Elevated levels of Lp(a) correlate with increased risk of acute coronary syndromes, cerebrovascular accident, peripheral arterial disease, and coronary mortality. This Q&A session answers some curiosities about Lipoprotein(a).
