Examination of the role of the colloids hydroxyethylstarch, dextran, human albumin, and plasma proteins in a modified UW solution.

The delayed contralateral nephrectomy procedure (three-step) produced inconsistent results, indicating that the preserved autotransplanted kidney tends to remain unfunctional and to regenerate incompletely unless the demand for work is placed upon it. Omission of HES in UW (UW-plain) did not affect preservation success, but resulted in increased graft edema. Substitution of HES in UW with plasma (SGF-V) or albumin (MAlb) gave significantly worse results than UW-like solutions with or without synthetic colloids. Replacement of HES in UW with UMdex-70 or UMdex-500 gave nonsignificantly worse results than UW-like solutions with or without synthetic colloids. The use of UMdex-40 as the main colloid in UW cheapened the solution, equalled the preservation success of UW and UW-plain but surpassed UW-plain in edema prevention, and exceeded UW concerning recovery of graft microcirculation.     

Renal transplantation for patients 60 years of older. A single-institution experience.

OBJECTIVE: The authors reviewed renal transplant outcomes in recipients 60 years of age or older. BACKGROUND: Before cyclosporine, patients older than 45 years of age were considered to be at high risk for transplantation. With cyclosporine, the age limits for transplantation have expanded. METHODS: The authors compared patient and graft survival, hospital stay, the incidence of rejection and rehospitalization, and the cause of graft loss for primary kidney recipients 60 years of age or older versus those 18 to 59 years of age. For those patients > or = 60 years transplanted since 1985, the authors analyzed pretransplant extrarenal disease and its impact on post-transplant outcome. In addition, all surviving recipients > or = 60 years completed a medical outcome survey (SF-36). RESULTS: Patient and graft survival for those > or = 60 years of age versus those 18 to 59 years of age were similar 3 years after transplant. Subsequently, mortality increased for the older recipients. Death-censored graft survival was identical in the two groups. There were no differences in the cause of graft loss. Those 60 years of age or older had a longer initial hospitalization, but had fewer rejection episodes and fewer rehospitalizations. Quality of life for recipients 60 years of age or older was similar to the age-matched U.S. population. CONCLUSION: Renal transplantation is successful for recipients 60 years of age or older. Most of them had extrarenal disease at the time of transplantation; however, extrarenal disease was not an important predictor of outcome and should not be used as an exclusion criterion. Post-transplant quality of life is excellent.     

Recurrence of disease in patients retransplanted for focal segmental glomerulosclerosis.

The natural history of focal segmental glomerulosclerosis in patients retransplanted after loss of a primary allograft is not well established. We studied 14 patients with FSGS who were retransplanted between April 1964 and September 1990 to determine if recurrence in a second or subsequent allograft could be predicted. In this group, 8 of the primary allografts were lost to recurrent disease and 6 to rejection. None of the 6 patients who lost their primary allograft to rejection without evidence of recurrent FSGS suffered recurrent disease after retransplantation. In contrast, 3 of the 8 patients who lost their primary allograft rapidly to FSGS suffered recurrent disease and loss of function in all subsequent allografts. The remaining 5 patients had prolonged function of the primary allograft ranging between 4 and 10.5 years, despite recurrence of FSGS. Of these 5 patients, 2 have excellent renal function after retransplantation without recurrence of FSGS in the secondary allograft at 9 and 10.5 years posttransplant; 2 have lost their secondary allograft to recurrent FSGS, but are free of recurrence in the third allograft at 0.5 and 5.8 years postoperatively; 1 maintains a serum creatinine level of 1.9 mg% despite recurrence of FSGS in the secondary allograft at 1 year postoperatively. Our data show that, without recurrence of FSGS in the primary allograft, further renal transplants will be free of recurrent disease. Based on this finding, we advocate use of living-related donors for second transplants in these patients. With rapid recurrence of FSGS and subsequent accelerated loss of the primary allograft, further renal transplants carry a high likelihood of recurrent FSGS and graft loss. A substantial proportion of patients with recurrent FSGS in the primary allograft will have prolonged renal function, and are likely to have excellent results with subsequent allografts.     

Posttraumatic stress reactions after single and double trauma

This study evaluated the severity and symptom profile of posttraumatic stress reactions of 202 adults exposed in 1988 to political violence in Azerbaijan and/or the earthquake in Armenia. High rates of severe posttraumatic stress reactions were found among the most highly exposed individuals, irrespective of the type of trauma. There was no difference in symptom profile for subjects exposed to earthquake versus violence. These similarities in severity and symptom profile may be attributable to common features of the exposures, which included experiencing life-threat and witnessing injury, mutilation and death. Recent prior exposure to violence contributed to the severity of reaction to the earthquake. The high rates of chronic and severe posttraumatic stress reactions in Armenia constitute a major public mental health problem.
