Factors associated with improved short term survival in obese end stage renal disease patients.

Purpose: In contrast to its role in the general population, obesity, defined as body mass index (BMI) > or = 30 kg/m(2), has been associated with improved survival in patients with end stage renal disease (ESRD). This apparent benefit has not been explained.

Methods: Using the United States Renal Data System (USRDS), we performed an historical cohort study on 151,027 patients initiated on ESRD therapy between January 1, 1995 and June 30, 1997, who never received renal transplants, and who had information sufficient to calculate BMI.

Hospitalizations for cytomegalovirus disease after renal transplantation in the United States.

Purpose: Risk factors, sites, and mortality of hospitalized cytomegalovirus (CMV) disease in renal transplant recipients have not been studied in a national population.

Methods: Therefore, 33,479 renal transplant recipients in the United States Renal Data System from 1 July 1, 1994 to June 30, 1997 were analyzed in an historical cohort study of patients with a primary discharge diagnosis of CMV disease (ICD9 Code 078.5x).

Hospitalizations for bacterial pneumonia after renal transplantation in the United States.

Purpose: Bacterial pneumonia has been cited as the leading cause of infectious death in renal transplant recipients but has not been studied in a national transplant population.

Subject And Methods: Retrospective analysis of the incidence, risk factors and mortality of hospitalized bacterial pneumonia (ICD9 Code 481.x486.

Acute coronary syndromes after renal transplantation in patients with end-stage renal disease resulting from diabetes.

Coronary heart disease is the leading cause of death in both diabetes mellitus and end-stage renal disease. Although renal transplantation is known to reduce mortality in end-stage renal disease, its effect on the incidence of acute coronary syndromes is unknown. Using data from the United States Renal Data System, we studied 11,369 patients with end-stage renal disease due to diabetes enrolled on the renal and renal-pancreas transplant waiting list from 1 July 1994 to 30 June 1997.

Effect of donor factors on early graft survival in adult cadaveric renal transplantation.

Previous studies of the effect of donor factors on renal transplant outcomes have not tested the role of recipient body mass index, donor/recipient weight ratios and age matching, and other factors. We analyzed 20,309 adult (age 16 or older) recipients having solitary cadaveric renal transplants from adult donors from 1 July 1994 to 30 June 1998 in an historical cohort study (the 2000 United States Renal Data System) of death censored graft loss by the Cox proportional hazards models, which corrected for characteristics thought to affect outcomes. The only independently significant findings in Cox Regression analysis were a high donor/ recipient age ratio (> or = 1.

Chronic dialysis patients have high risk for pulmonary embolism.

Pulmonary embolism has been considered uncommon in chronic dialysis patients, but has not been adequately studied in a large population. In the US Renal Data System (USRDS), 76,718 patients presenting with end-stage renal disease (ESRD) between January 1, 1996, and December 31, 1996, were analyzed in an historical cohort study. The outcome was hospitalizations with a primary discharge diagnosis of pulmonary embolism (International Classification of Diseases, Ninth Revision code 415.

Hospitalized congestive heart failure after renal transplantation in the United States.

Purpose: African Americans have increased risk for congestive heart failure (CHF) compared to Caucasians in the general population, but the risk of CHF in African American renal transplant recipients has not been studied in a national renal transplant population.

Methods: Therefore, 33,479 renal transplant recipients in the United States Renal Data System (USRDS) from 1 July, 1994 to 30 June, 1997 were analyzed in an historical cohort study of the incidence, associated factors, and mortality of hospitalizations with a primary discharge diagnosis of CHF [International Classification of Diseases-9 (ICD9) Code 428.x].
