The frequency and outcome of recurrent lupus nephritis (RLN) among recipients of a kidney allograft vary among single-center reports. From the United Network for Organ Sharing files, we estimated the period prevalence and predictors of RLN in recipients who received a transplant between 1987 and 2006 and assessed the effects of RLN on allograft failure and recipients' survival. Among 6850 recipients of a kidney allograft with systemic lupus erythematosus, 167 recipients had RLN, 1770 experienced rejection, and 4913 control subjects did not experience rejection. The period prevalence of RLN was 2.44%. Non-Hispanic black race, female gender, and age Ͻ33 years each independently increased the odds of RLN. Graft failure occurred in 156 (93%) of those with RLN, 1517 (86%) of those with rejection, and 923 (19%) of control subjects without rejection. Although recipients with RLN had a fourfold greater risk for graft failure compared with control subjects without rejection, only 7% of graft failure episodes were attributable to RLN compared and 43% to rejection. During follow-up, 867 (13%) recipients died: 27 (16%) in the RLN group, 313 (18%) in the rejection group, and 527 (11%) in the control group. In summary, severe RLN is uncommon in recipients of a kidney allograft, but black recipients, female recipient, and younger recipients are at increased risk. Although RLN significantly increases the risk for graft failure, it contributes far less than rejection to its overall incidence; therefore, these findings should not keep patients with lupus from seeking a kidney transplant.

We report the first case of bone marrow cell transplantation to the myocardium of a patient with heart failure due to chagas' disease. The patient is a 52-year-old man with chronic heart failure, NYHA functional class III, despite the optimized clinical therapy. The procedure consisted of aspiration of 50 mL of bone marrow through puncture of the iliac crest, followed by filtration, separation of the mononuclear cells, resuspension, and intracoronary injection. The left ventricular ejection fraction at rest, measured using radionuclide ventriculography with labeled red blood cells prior to transplantation, was 24%, and, after 30 days, it increased to 32% with no change in the medicamentous schedule. The following measurements were assessed before and 30 days after transplantation: left ventricular end diastolic diameter (82 mm and 76 mm, respectively); Minnesota living with heart failure questionaire score (55 and 06, respectively); and distance walked in the 6-minute walking test (513 m and 683 m, respectively). Our findings show that intracoronary injection of bone marrow cells may be performed, suggesting that this is a potentially safe and effective procedure in patients with due to Chagas' disease heart failure.

Among veterans, traditional cardiovascular risk factors, CVD, and CKD are highly prevalent. CKD is associated with increased risk of baseline CVD and follow-up mortality.
