Efficacy of Daclizumab in an African-American and Hispanic renal transplant population.

Current immunosuppressive regimens have decreased acute rejection rates during the 1st year after renal transplantation. However, this decrease has not been as marked in high-risk groups, such as African-American and Hispanic renal transplant recipients. We compared two simultaneous cohorts of altogether 36 African-American and Hispanic renal transplant recipients.

Suppression of parathyroid hormone secretion in hemodialysis patients by a novel vitamin D analogue: 19-nor-1,25-dihydroxyvitamin D2.

In this double-blind, placebo-controlled, randomized, multicenter study, 35 patients with end-stage renal disease undergoing maintenance hemodialysis were treated three times weekly for 4 weeks with either 19-nor-1,25-dihydroxyvitamin D2 (paricalcitol) intravenously at doses ranging from 0.04 to 0.24 microg/kg or placebo.

The role of anaerobic bacteria in the pathogenesis of urinary tract infections.

Because of the rarity of anaerobic infections of the urinary tract and the difficulty of establishing these organisms as pathogens, anaerobic culture is not included as part of routine urine bacteriological examination. Pyuria was found during examination of a 41-year-old man with a chronic renal allograft rejection reaction. Aerobic urine cultures failed to yield any pathogens.

Duration of hepatitis B surface antigenemia (HBs Ag) in hemodialysis patients.

Follow-up studies were done on 231 hemodialysis patients during a period of from one to 48 months to determine the natural history of hepatitis B surface antigenemia (HBs Ag). Of those studied, 113 (49%) exhibited HBs Ag. The probability of remaining HBs Ag positive over the mean follow-up period of 14.
