Coadministration with the human immunodeficiency virus (HIV) protease inhibitor ritonavir was investigated as a method for enhancing the levels of other peptidomimetic HIV protease inhibitors in plasma. In rat and human liver microsomes, ritonavir potently inhibited the cytochrome P450 (CYP)-mediated metabolism of saquinavir, indinavir, nelfinavir, and(More)
BACKGROUND Intensive therapy of HIV infection with highly active antiretroviral therapy (HAART) dramatically reduces viral loads and improves immune status. Abnormalities of lipid levels, body fat distribution, and insulin resistance have been commonly reported after starting HAART. Whether the lipid abnormalities result from changes in metabolism after an(More)
Five percent 5-fluorouracil (5-FU), an antineoplastic agent, is often applied to the lower genital tract in the treatment of vaginal and vulvar human papillomavirus infections. Little is known regarding possible teratogenic effects from its topical use in pregnancy. Five cases of antenatal lower genital tract 5-FU use were correlated with pregnancy outcome.(More)
We sought to determine whether women infected with human immunodeficiency virus (HIV) had cervicovaginal cellular changes suggesting lower genital tract neoplasia or human papillomavirus (HPV) infection at a rate different from that in women without HIV infection. In a blinded fashion, cytological preparations of cervicovaginal smears from women infected(More)
BACKGROUND Ritonavir, a potent antiretroviral protease inhibitor, has been approved for the treatment of adults and children with human immunodeficiency virus (HIV) infection. In a phase I/II study, we assessed the safety, tolerability, and pharmacokinetic profile of the oral solution of ritonavir in HIV-infected children and studied the preliminary(More)
OBJECTIVE To determine whether interferon alpha-2a, when utilised as adjuvant chemotherapy following ablation of condylomata acuminata (genital warts) by cryotherapy, is effective in the prevention of recurrences. DESIGN Randomised, placebo-controlled, double-blind study. Statistical analysis was by 2-tailed Fisher's Exact Test. PATIENTS 97 patients(More)
To the Editor: Liver toxicity is the most common reason for drug withdrawals (1). Drug-related hepatotoxicity is rare, however, and therefore may not be detected in pre-marketing clinical trials. In the case of drugs developed for orphan diagnoses, the clinical trial experience is invariably even smaller. Post-marketing experience then becomes essential in(More)
Skillful laser ablation can remove any volume of human papillomavirus-associated vulvar disease but cannot prevent reactivation of the surrounding latent viral reservoir during postoperative healing. Conversely, interferon and 5-fluorouracil are relatively ineffective as primary therapies in clearing bulky lesions. In this study of 71 assessable patients,(More)
Although most human papillomavirus infections can be managed satisfactorily by office methods, extensive, refractory, and dysplastic vulvar disease poses frustrating problems. This observational cohort study evaluated the efficacy of extended laser ablation (vaporization of both clinically apparent and adjacent subclinical changes) among 160 women drawn(More)
