Prevalence of adverse events associated with potent antiretroviraltreatment: Swiss HIV Cohort Study Jacques Fellay, Karim Boubaker, Bruno Ledergerber, Enos Bernasconi, Hansjakob Furrer, Manuel Battegay, Bernard Hirschel, Pietro Vernazza, Patrick Francioli, Gilbert Greub, Markus Flepp, Amalio Telenti, for the Swiss HIV Cohort Study* IntroductionBecause so many retroviral agents are available, clinicians need a precise understanding of the efficacy treatment have been recorded in clinical trials, post- and toxic effects of the various drug combinations. When marketing analyses, and anecdotal reports. Such data efficacy is similar, the choice of combination will be might not be an up-to-date or comprehensive assessment of affected by the toxic effects of the drugs. Adverse all possible treatment combinations defined as potent reactions have been recorded anecdotally and in randomised clinical trials,1–3 but, little information isavailable about prevalence and severity of adverse events Methods Using a standard clinical and laboratory method, in routine clinical practice. To describe the pattern of we assessed prevalence of adverse events in 1160 clinical and laboratory abnormalities potentially patients who were receiving antiretroviral treatment. We associated with antiretroviral treatment, and to compare measured the toxic effects associated with the drug the prevalence of adverse events between drug regimens regimen (protease inhibitor [PI], non-nucleoside and and for various antiretroviral agents, we have done a nucleoside analogue reverse transcriptase inhibitor) and cross-sectional, observational study of 1160 patients who specific compounds using multivariate analyses. were receiving potent antiretroviral treatment. We did two types of analyses. First, we did a Findings 47% (545 of 1160) of patients presented with structured interview and laboratory analysis to identify clinical and 27% (194 of 712) with laboratory adverse and describe all potential adverse events attributed to events probably or definitely attributed to antiretroviral treatment according to standard definitions. Second, we treatment. Among these, 9% (47 of 545) and 16% (30 of identified independent associations using logistic 194), respectively, were graded as serious or severe.

This approach could be a useful strategy in associated with a comparable prevalence of adverse postmarketing analysis of the toxic effects of drugs used events. Compared with single-PI treatment, use of dual-PI- antiretroviral treatment and three-class-antiretroviraltreatment was associated with higher prevalence of adverse events (odds ratio [OR] 2·0 [95% CI 1·0–4·0], and 3·9 [1·2–12·9], respectively).

multivariate analysis that accounted for stage of diseaseas measured by CD4 cell count, viraemia concentration, and use of comedication for opportunistic illnesses, single-PI-antiretroviral treatment and PI-sparing- antiretroviral treatment had closely similar prevalence of adverse events. Compared with single-PI-antiretroviral treatment, use of dual-PI-antiretroviral treatment and three-class-antiretroviral treatment were associated with higher prevalence of adverse events (OR 2·0 [95% CI 1·0–4·0] and 3·9 [1·2–12·9], respectively).
Table 2 lists all associations identified in the logistic analysis. Compared with single-PI-antiretroviral treatment, use of three-class-antiretroviral treatment was associated with greater risk of diarrhoea, and increased concentrations of cholesterol, triglyceride, alkaline phosphatase, and lactate. Use of dual-PI- antiretroviral treatment was associated with greater risk of fever and diarrhoea, and increased concentrations of cholesterol, triglyceride, and alkaline phosphatase. Use of PI-sparing-antiretroviral treatment was associated with greater risk of vomiting, mood and sleep disorders, and increased concentrations of amylase; but reduced risk of diarrhoea, and increased concentrations of Table 3 lists all adverse events attributed to specific antiretroviral treatment by logistic analysis. In patients taking nucleoside reverse transcriptase inhibitors, lamivudine was independently associated with mood disorders and lipodystrophy; stavudine with headache, lipodystrophy, and rise in serum concentrations of urate, creatine phosphokinase, lactate, cholesterol, and triglyceride; didanosine with increase in urate and lactate concentrations; and abacavir with vomiting and increasein creatine phosphokinase concentrations. There was atrend towards an association between zidovudine and anaemia. Use of zidovudine and lamivudine in combination was associated with neutropenia. In patients on PI, ritonavir was independently associated with diarrhoea, hyperbilirubinaemia, and increases in cholesterol and triglyceride concentrations; saquinavir with diarrhoea and thrombocytopenia; indinavir with nephrolithiasis, rash, and hyperbilirubinaemia; and nelfinavir with diarrhoea.
