Abstract:
A 67-year-old man received interferon alpha (IFN alpha) therapy for lung metastases of renal cell carcinoma (RCC). Multiple pulmonary metastases disappeared completely. However, neurological toxicity was detected by magnetic resonance imaging (MRI) as abnormal brain lesions. After discontinuation of IFN alpha therapy, his neurological symptoms and abnormal lesions on MRI disappeared completely. Complete remission of RCC has continued, and results of neurological study have remained normal for 5 years after discontinuation of IFN alpha therapy.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
