To describe participation in clinical trials among HIV-positive women enrolled since 1993 in the Canadian Women's HIV Study, a prospective open cohort study. ⋯ Although the overall clinical trial participation rate of 23.5% was relatively high among HIV-positive women, injection drug users were underrepresented in this study population, and non-white women, women who did not complete high school and women not receiving antiretroviral therapy were less likely than white women, women of higher education and women receiving antiretroviral therapy to participate in clinical trials in Canada. Because of the importance of trial participants being representative of the population for which therapeutic agents are intended, HIV clinical trials must recruit women with lower literacy levels, non-white women, women not receiving antiretroviral therapy and women who are injection drug users to ensure generalizability of research findings. Further study is needed to assess factors that act as barriers and motivators to women's participation in HIV clinical trials.

Case Reports
Reversible impairment of renal function associated with enalapril in a diabetic patient.
Acute renal failure and hyperkalemia due to angiotensin-converting enzyme inhibitors have been described in diabetic patients with other predisposing conditions. The case reported here involves a patient with type 1 diabetes mellitus, microalbuminuria and normal renal function who was treated with enalapril. Two years after initiation of this therapy, at a time when glycemic control was poor, he presented with symptomatic hyperkalemia and impaired renal function accompanied by hyporeninemic hypoaldosteronism. This case illustrates that reversible impairment of renal function and hyperkalemia can present after 2 years of treatment with angiotensin-converting enzyme inhibitors in patients with precipitating factors.
