Randomized Controlled Trial Multicenter Study
Peginesatide for anemia in patients with chronic kidney disease not receiving dialysis.
Peginesatide is a peptide-based erythropoiesis-stimulating agent (ESA) that may have therapeutic potential for anemia in patients with advanced chronic kidney disease. We evaluated the safety and efficacy of peginesatide, as compared with another ESA, darbepoetin, in 983 such patients who were not undergoing dialysis. ⋯ The efficacy of peginesatide (administered monthly) was similar to that of darbepoetin (administered every 2 weeks) in increasing and maintaining hemoglobin levels. However, cardiovascular events and mortality were increased with peginesatide in patients with chronic kidney disease who were not undergoing dialysis. (Funded by Affymax and Takeda Pharmaceutical; ClinicalTrials.gov numbers, NCT00598273 [PEARL 1], NCT00598442 [PEARL 2], NCT00597753 [EMERALD 1], and NCT00597584 [EMERALD 2].).

The disease risks from cigarette smoking increased in the United States over most of the 20th century, first among male smokers and later among female smokers. Whether these risks have continued to increase during the past 20 years is unclear. ⋯ The risk of death from cigarette smoking continues to increase among women and the increased risks are now nearly identical for men and women, as compared with persons who have never smoked. Among men, the risks associated with smoking have plateaued at the high levels seen in the 1980s, except for a continuing, unexplained increase in mortality from COPD.
