Articles

  • This pilot study randomly assigned patients to receive one of two triple-drug regimens (stavudine, didanosine, and efavirenz or zidovudine, lamivudine, and nelfinavir) or to alternate between the two regimens every 3 months. Alternating the regimens delayed virologic failure.

  • The angiotensin-receptor antagonist losartan reduces urinary albumin excretion in normotensive patients with type 2 diabetes and microalbuminuria. The effect of losartan on proteinuria is independent of its effect on blood pressure.

  • Statin use did not reduce fracture risk or increase bone density in the Women's Health Initiative Observational Study. The accumulated evidence does not support using statins to prevent or treat osteoporosis.

  • The angiotensin-converting enzyme inhibitor ramipril may reduce the rate of decline in residual renal function in patients who have end-stage renal failure and are undergoing peritoneal dialysis.

Academia and Clinic

  • Observation, culture, and two rapid antigen test strategies for diagnosing and treating suspected group A β-hemolytic streptococcal (GAS) pharyngitis in adults have very similar cost-effectiveness. Culture is the least expensive and most effective strategy for pharyngitis when the probability of GAS is 10% or greater. Empirical antibiotic treatment is never the best strategy in adults, except possibly in patients with a very high probability of GAS.

Review

  • This review discusses the risks and complications of percutaneous coronary revascularization, as well as optimum patient management before, during, and after the procedure.

Clinical Guidelines

  • This paper describes a classification system for chronic kidney disease and summarizes recommendations on early detection in adults. Key recommendations include identifying persons at increased risk, using the albumin–creatinine ratio in untimed urine specimens, and using prediction equations to estimate the glomerular filtration rate from the serum creatinine level.

Editorials

  • In Martinez-Picado and colleagues' study reported in this issue, fewer virologic failures occurred with alternating antiretroviral regimens than with continuous treatment with one triple-drug regimen. However, several subtleties in the study design and the analysis raise questions about the meaning of the findings and their application to clinical practice.

  • In this issue, Neuner and colleagues report a cost-effectiveness analysis of the diagnosis and treatment of adults with pharyngitis caused by group A β-hemolytic streptococcus. Contrary to a recent American College of Physicians practice guideline, they found that treatment based on history and physical findings alone was the least effective strategy. Until controlled clinical studies measure the added value of the rapid antigen test or culture for GAS, the author does not believe it is prudent to rely exclusively on clinical criteria to diagnose and manage pharyngitis.
