NEW ORLEANS—Acute renal failure (ARF) induced by pathogenic light chains can be the first presenting sign of multiple myeloma, and prompt treatment of the malignancy is critical to reversing renal damage, according to a study presented by European investigators at the American Society of Hematology 51st annual meeting.

Acute renal damage may resolve in the absence of the underlying cause.

They are less likely than men to suffer acute renal failure and other complications, researchers say.

Researcher Macaulay Onuigbo, MD, MSc, proposes that ACE inhibitors and angiotensin receptor blockers can cause renal failure.

ORLANDO—Acute renal failure (ARF) may be more likely to develop following coronary artery bypass grafting (CABG) than percutaneous coronary intervention (PCI), according to researchers.

THE FDA is recommending that only prescription oral sodium phosphate (OSP) bowel preparations be used by patients for bowel cleansing prior to undergoing colonoscopy. The agency also is requiring "black box" warnings on these products.

In a seemingly paradoxical manner, observational studies examining outcomes in patients suffering from CKD have found significantly altered risk-factor patterns such that conventional mortality risk factors have been associated with better survival; this phenomenon was termed "reverse epidemiology" or "risk factor paradox."

Ferumoxytol, a novel, semi-synthetic, superparamagnetic iron oxide nanoparticle administered by injection, is well tolerated and has a safety profile similar to placebo in CKD patients with anemia, according to a report in the American Journal of Kidney Diseases.

IV CALCITRIOL treatment in patients with early-stage secondary hyperparathyroidism prevents parathyroid (PT) gland growth, researchers report.

SAN FRANCISCO—Multiplying total motile sperm count by the percent of normal sperm determined by strict morphology (TM×SM) may be a significant predictor of pregnancy when sperm morphology is less than 5%, according to a new study by Texas researchers.
