Abstract: | Objective To compare the profile of adverse drug reactions (ADRs) to antiretroviral (ARV) drugs in patients coinfected with hepatitis
C virus (HCV) or hepatitis B virus (HBV) versus non-coinfected patients with human immunodeficiency virus (HIV) infection.
Methods We used the French Pharmacovigilance Database from 2000 to 2002. Selected patients were classified into four groups: HIV+HCV,
HIV+HBV, HIV+HBV+HCV and HIV patients. We compared patients’ characteristics and profiles of ADRs to ARV drugs between the
four groups.
Results We identified 1,068 HIV, 172 HIV+HCV, 72 HIV+HBV and 26 HIV+HBV+HCV patients with 2,398, 446, 183 and 70 ADRs related to ARV
drugs, respectively. The “seriousness” of these ADRs was similar in HIV and coinfected patients but death related to the ADRs
was more frequent in HIV+HCV (9.4%) than in HIV (3.6%) patients (p<0.001). “Liver and bile system disorders” were more frequently reported in HIV+HCV and HIV+HBV patients than in HIV patients
(17.3% and 20.8%, respectively, versus 8.9%, p<0.001). In HIV+HBV patients, the occurrence of these ADRs was independently associated in a logistic regression model to
male gender odds ratio (OR): 9.28, 95% confidence interval (CI): 2.74–31.36], exposure to zalcitabine (OR: 17.82, 95% CI:
1.49–212.95) or efavirenz (OR: 5, 95% CI: 1.44–17.33). “Red blood cell disorders” were also more frequent in HIV+HCV (7.4%)
than in HIV (4.4%) patients (p<0.01).
Conclusion Hepatic or haematological (mainly anaemia) ADRs to ARV drugs are more frequent in coinfected patients than in HIV patients.
This study underlines the importance of hepatitis B or C in the occurrence of ADRs in HIV patients on ARV drugs. |
