With respect to elderly patients: finding kidneys in the context of new allocation concepts.

The elderly have benefited from increased access to renal transplantation in recent years. New allocation concepts would shift distribution of kidneys to younger recipients, making expanded criteria and living donor kidneys more relevant for seniors. Current issues impacting expanded criteria donor kidney availability and living donor transplant opportunities for the elderly are explored. It is hoped that the kidney donor profile index will improve risk assessment and utilization of marginal kidneys. The usefulness of procurement biopsy remains controversial. Dual kidney transplantation and machine perfusion appear to be effective mechanisms to increase organ availability. "Old-for-old" allocation systems, donation service area variation and regulatory and reimbursement issues highlight disparities and disincentives affecting expanded criteria donor organ utilization, and considerations for the way forward are discussed. Living donor transplantation, even with older donors, may provide the best option for elderly recipients, and careful expansion of the living donor pool appears appropriate. In light of new allocation concepts, it will be important to understand issues pertinent to seniors and develop effective strategies to maintain or improve their access to the benefits of transplantation.

Impact of serum lipids on long-term graft and patient survival after renal transplantation.

The results after primary cadaveric renal transplantation in 665 consecutive patients were reviewed with respect to posttransplant serum lipids. Data were available for 182 of 665 patients on serum total cholesterol and triglycerides at 1 year posttransplant. Hypercholesterolemia (cholesterol > 200 mg/dl) developed in 141 of 182 patients (77%) and hypertriglyceridemia developed in 73 of 166 patients (44%). At 1 year posttransplant, hypercholesterolemia and hypertriglyceridemia both correlated with age at transplant (P = 0.0001, P = 0.01). Hypercholesterolemia and hypertriglyceridemia were also correlated with obesity as determined by body mass index (kg/m2) (P = 0.006, P = 0.01). Hypertriglyceridemia at 1 year posttransplant correlated with pretransplant triglyceride level (P = 0.006), but hypercholesterolemia did not correlate with pretransplant cholesterol level (P = 0.53). Hyperlipidemia was not correlated with cyclosporine (CsA) or prednisone dose (mg/kg), CsA trough levels, number of rejection episodes, or serum creatinine at 1 year. Despite significant differences in serum cholesterol and triglycerides, actuarial graft and patient survival were similar between the normolipidemic and hyperlipidemic groups.

Gastric carcinoma in the young.

Thirty-eight cases of gastric carcinoma in patients 35-years-old and younger, occurring in the period 1948 to 1983, are reviewed. They comprised 2.2% of 1710 cases in all ages for the same 35 year period at the Charity Hospital. Women were afflicted as commonly as men. Blacks outnumbered whites 2.9:1.0. Obstruction, pain, and weight loss of relatively short duration were prominent symptoms. Tumors tended to be located distally in the stomach, and scirrhous in appearance. Histologically, diffuse type lesions were more common than intestinal or other type tumors. Radiographic evidence of disease was usually present in patients undergoing upper gastrointestinal series. Endoscopy with biopsy was a valuable diagnostic tool. Resectability in this group was not less than that achieved for all ages, however, only one patient has survived for five years. Advanced stage lesions predominated and were associated with poor survival. Earlier stage lesions in this age group appear to bear a more favorable prognosis.
