Improving survival after renal transplantation for diabetic patients with severe coronary artery disease.

After successful renal transplantation, seven diabetic renal failure patients with severe coronary artery disease returned to productive employment. Despite the requirement for additional peripheral vascular or ophthalmologic surgery in four patients, their renal function remained adequate. Following transplantation, diabetic complications included angina in three, myocardial infarction in three, and cerebrovascular accident in two patients. Two patients with adequate renal function died suddenly at 29 and 62 mo. Despite severe coronary artery disease, an increasing number of diabetic dialysis patients may be able to return to work after a successful kidney transplant.

Long-term responses of women to indole-3-carbinol or a high fiber diet.

We test the hypothesis that the estrogen metabolite ratio 2-OH-estrone:estriol can be raised via dietary indole-3-carbinol (I3C) and that this higher ratio can be sustained over a 3-month test period. We also explore the possible role of pure fiber on estradiol metabolism. Using a randomized clinical trial with three arms, each containing 20 subjects, arm 1 received 400 mg/day of I3C daily for 3 months, arm 2 received 20 g of alpha-cellulose daily for the same time period as a source of added fiber, and arm 3 received a placebo dose. Blood levels of a variety of biochemical parameters were measured. The urinary 2-OH-estrone:estriol estrogen metabolite ratio was measured monthly at the same time of the menstrual cycle. While no changes were observed in the control and alpha-cellulose-treated arms, a substantial mean increase in the ratio was observed in the I3C-treated arm at month 1; that increase was maintained over the 3-month time period. Three of the 20 subjects in this I3C-treated group differed from the others in that no significant change in the metabolite ratio was observed at any time point. The results suggest that I3C can serve to increase the 2-OH-estrone:estriol metabolite ratio in a sustained manner without detectable side effects and that some individuals may be resistant to such change.

erbB-2 and myc oncoproteins in sera and tumors of breast cancer patients.

This study compares the prevalence of elevated serological levels of erbB-2 and myc proteins in 36 breast cancer patients and 25 healthy, ambulatory female controls. The controls were frequency matched to the cases by age and ethnicity. Oncoprotein levels were determined blind to the "case-control status" of the individual from whom the specimen was derived. Corresponding tissue levels were examined in tumors of the 13 cases from whom sufficient tissue was available. Serum oncoproteins were elevated as follows: erbB-2 in one control (4%) compared with nine cases (25%; PFisher's exact = 0.03); myc in no control (0%) compared with seven cases (19%; PFisher's exact = 0.02). Elevated serum levels of erbB-2 or myc oncoproteins were detected in four of the seven cases (57.1%) of in situ cancer without evidence of infiltration. In all cases with elevated serum oncoproteins where tumor tissue was available, the corresponding protein was elevated in the tumor. The three cases who had elevated preoperative serum oncoprotein levels and from whom it was possible to procure postoperative specimens had normal postoperative serum oncoprotein levels. We conclude that (a) erbB-2 and myc oncoproteins are elevated in a proportion of breast cancer patients, (b) the tumor seems to be the source of the serum elevation, and (c) these proteins may be useful as part of a panel of biomarkers of early malignant disease.
