Résumé

BACKGROUND: Abacavir is a widely-used nucleoside reverse transcriptase inhibitor for the treatment of human immunodeficiency virus (HIV) infection. Mandatory postmarketing surveillance was conducted in Korea to monitor the safety and evaluate the effectiveness of Ziagen® (abacavir sulfate 300 mg; ViiV Healthcare, Middlesex, UK). MATERIALS AND METHODS: An open-label, multi-center, non-interventional postmarketing surveillance study was conducted from June 2010 to June 2016 to monitor the safety and effectiveness of Ziagen across 12 hospitals in Korea. Subjects older than 18 years taking Ziagen according to prescribing information were enrolled. The primary outcome was defined as the occurrence of any adverse events after Ziagen administration. Secondary outcomes included the occurrence of adverse drug reactions, occurrence of serious adverse events, and effectiveness of Ziagen administration. RESULTS: A total of 669 patients were enrolled in this study, with a total observation period of 1047.8 person-years. Of these, 90.7% of patients were male. The mean age of patients was 45.8±11.9 years. One-hundred ninety-six (29.3%) patients reported 315 adverse events, and four patients reported seven serious adverse events, without any fatal events. There was one potential case of an abacavir hypersensitivity reaction. Among the 97 adverse drug reactions that were reported from 75 patients, the most frequent adverse drug reactions included diarrhea (12 events), dyspepsia (10 events), and rash (9 events). No ischemic heart disease was observed. In the effectiveness analysis, 91% of patients achieved HIV-1 RNA under 50 copies/mL after 24 months of observation with abacavir administration. CONCLUSION: Our data showed the safety and effectiveness of Ziagen in a real-world setting. During the study period, Ziagen was well-tolerated, with one incident of a clinically suspected abacavir hypersensitivity reaction. The postmarketing surveillance of Ziagen did not highlight any new safety information. These data may be helpful in understanding abacavir and the HIV treatment practices in Korea.

Résumé

PURPOSE: With the increase in vancomycin use, adverse drug reactions (ADRs) associated with vancomycin have been reported increasingly more often. However, the characteristics of cutaneous ADRs with and without systemic reactions (SRs) have not been described. This study investigated the characteristics of spontaneously reported and assessed ADRs associated with vancomycin by a pharmacovigilance center. METHODS: ADRs (n=121) associated with vancomycin in 96 patients were collected from 2008 to 2009. Records from physician- and nurse-reported suspected cases of vancomycin ADRs, ADR type, latent period, and laboratory results were compared between cutaneous ADRs with and without SRs. RESULTS: The main vancomycin-related ADRs were skin rashes (47.9%), hematologic abnormalities (17.36%), fever (12.4%), and elevated serum creatinine (12.4%). Significant differences were observed in latent period (days) and the mean change in eosinophils (%) between cutaneous (9.21+/-9.71 and 1.4+/-3.4, respectively) and other ADRs (14.03+/-11.71 and -0.5+/-3.5, respectively). Twelve cases of cutaneous ADRs with SRs had been initially reported as cutaneous ADRs only. Mean changes in the eosinophil count were significantly higher for cutaneous ADRs with SRs compared to those without SRs. CONCLUSIONS: Skin rashes accompanied by peripheral eosinophilia, representing suspected immune-mediated delayed hypersensitivity reactions, are a common vancomycin ADR. For the early and exact detection of ADRs associated with vancomycin administration, close monitoring of laboratory tests, including complete blood counts with differential analysis, is recommended.
