Optimizing Hepatitis C Therapy in HIV/hepatitis C Virus (HCV) Coinfected Patients: Analysis of HCV Viral Kinetics on Treatment
Notice bibliographique
Résumé
INTRODUCTION: Hepatitis C virus (HCV) infection is potentially curable, but the sustained virological response (SVR) has been shown to be lower in patients coinfected HIV. A single-centre experience treating individuals with HCV and HIV coinfection is reported. METHODS: Twenty-one patients who received standard doses of pegylated interferon with weight-based dosing of ribavirin (mean 14.3 mg/kg) were retrospectively reviewed. Qualitative HCV polymerase chain reaction (PCR) was performed prospectively every four weeks if the patient remained HCV PCR positive. All patients with HCV genotype 1 were treated for 48 weeks. Patients with genotype 2 or 3 were treated for 24 weeks and 32 weeks to 36 weeks if their HCV RNA level was undetectable after four weeks (RVR4) or eight weeks (RVR8) of therapy, respectively. If RVR8 was not achieved, the treatment was continued for 48 weeks. RESULTS: There were no dropouts or dose reductions within the first 12 weeks of treatment. SVR status was available for 20 patients and adequate serum for viral kinetics analyses was available for 17 patients. Eighty per cent of the patients achieved SVR (50% genotype 1; 100% genotypes 2 and 3). The week 8 viral load remained elevated for all genotype 1 nonresponders. DISCUSSION: High effectiveness rates were seen, particularly in patients with HCV genotype 2 and 3 who were treated for shorter durations. HCV viral loads after eight weeks of therapy helped distinguish patients with HCV genotype 1 who would respond to therapy.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
