BACKGROUND: Numerous studies have demonstrated that renal allograft survival is reduced in African-Americans (AAs). This posthoc racial subgroup analysis (AAs vs. non-AAs) tested whether mycophenolate mofetil (MMF) might have favorable implications for the treatment of AA renal allograft recipients. METHODS: Patients received a triple therapy regimen of corticosteroids, cyclosporine, and azathioprine (AZA) 1-2 mg/kg/day, MMF 2 g/day (MMF 2 g), or MMF 3 g/day (MMF 3 g). RESULTS: AAs in the AZA group had the highest biopsy-proven rejection/treatment failure (BPR/TF) rate (57.5% vs. 43.5% for non-AAs). AAs in the MMF 3 g group showed a significant reduction in BPR/TF (57.5% vs. 24.2%, P=0.0008). BPRs were more frequent for AAs in either the AZA (47.5%) or MMF 2 g group (31.8%) than in the MMF 3 g group (12.1%), whereas rejections were reduced for non-AAs receiving either MMF dosage (AZA, 35.5%; MMF 2 g, 15.7%; MMF 3 g, 18.8%). AAs in the AZA group experienced BPR/TF earlier than AAs in the MMF 3 g group (median onset at 64 days vs. > 183 days, P=0.0012). But AAs in the MMF 3 g experienced BPR/TF the latest among the six subgroups of treatment and race. AAs had more severe rejection episodes and higher serum creatinine levels at 6 months after transplant, regardless of treatment group. CONCLUSIONS: Dose-dependent prevention of acute rejection in AAs is best afforded by a dosage of MMF at 3 g/day, whereas 2 g/day provides a superior benefit/risk ratio for non-AAs. MMF at 3 g/day thus provides an improvement over conventional immunosuppressive strategies in reducing the frequency of acute rejections in this immunologically high-risk group.
BACKGROUND: Although antiandrogen withdrawal has moderate efficacy in patients with hormone refractory prostate carcinoma (HRPC), the effect of the simultaneous suppression of adrenal androgens with ketoconazole at the time of antiandrogen withdrawal is not known. METHODS: Twenty consecutive patients with HRPC who had developed progressive disease despite combined androgen blockade were treated with antiandrogen withdrawal and simultaneous ketoconazole as a means of inhibiting adrenal steroid production. Prostate specific antigen (PSA) response was defined as a > 50% fall in PSA from baseline that was maintained for at least 8 weeks. RESULTS: Ten patients had established metastatic disease, 2 had high PSAs and no imaging studies (PSA of 70 and 160 ng/mL, respectively), 3 had microscopically positive lymph nodes and serologic progression, and 5 had serologic progression alone. Overall, of 20 evaluable patients, 11 (55%) had a > 50% fall in PSA (95% confidence interval [CI], 31.5-76.9%). The median PSA response duration was 8.5 months (95% CI, 7-17 months). The median survival was 19 months. Toxicity was mild, with Grade 1 and 2 nausea and emesis in 15% of patients, Grade 1 fatigue in 10% of patients, and reversible Grade 1 or 2 hepatotoxicity in 10% of patients. Mild skin toxicity was observed in 20% of patients. CONCLUSIONS: The addition of ketoconazole and hydrocortisone to antiandrogen withdrawal appears to increase the PSA response proportion observed with antiandrogen withdrawal alone. Toxicity is mild.
