Abstract

Background The treatment of persistent symptoms attributed to Lyme disease remains controversial. Recently, the PLEASE study did not demonstrate any additional clinical benefit of longer term versus shorter-term antibiotic treatment. However, the economic impact of the antibiotic strategies has not been investigated. Methods This prospective economic evaluation, adhering a societal perspective, was performed alongside the PLEASE study, a multicenter, placebo-controlled, double-blind 1:1:1 randomized clinical trial in which all patients received open-label intravenous ceftriaxone for two weeks before the 12-week randomized blinded oral antibiotic regimen (doxycycline, clarithromycin plus hydroxychloroquine, or placebo). Between 2010 and 2013, patients (n = 271) with borreliosis-attributed persistent symptoms were enrolled and followed for one year. Main outcomes were costs, quality-adjusted life years, and incremental net monetary benefit of longer-term versus shorter-term antibiotic therapy. Results Mean quality-adjusted life years (95% CI) were not significantly different (p = 0.96): 0.82 (0.77-0.88) for ceftriaxone/doxycycline (n = 82), 0.81 (0.76-0.88) for ceftriaxone/clarithromycin-hydroxychloroquine (n = 93), and 0.81 (0.76-0.86) for ceftriaxone/placebo (n = 96). Total societal costs per patient (95% CI) were not significantly different either (p = 0.35): (sic)11,995 ((sic)8,823- 15,670) for ceftriaxone/doxycycline, (sic)12,202 ((sic)9,572- 15,253) for ceftriaxone/clarithromycin-hydroxychloroquine, and (sic)15,249 ((sic)11,294- 19,781) for ceftriaxone/ placebo. Incremental net monetary benefit (95% CI) for ceftriaxone/doxycycline compared to ceftriaxone/placebo varied from (sic)3,317 (-(sic) 2,199- 8,998) to (sic)4,285 (-(sic) 6,085-(sic)14,524) over the willingness-to-pay range, and that of ceftriaxone/clarithromycin-hydroxychloroquine compared to ceftriaxone/placebo from (sic)3,098 (-(sic)888-(sic)7,172) to (sic)3,710 (-(sic)4,254-(sic)11,651). For every willingness-to-pay threshold, the incremental net monetary benefits did not significantly differ from zero. Conclusion The longer-term treatments were similar with regard to costs, effectiveness and cost-effectiveness compared to shorter-term treatment in patients with borreliosis-attributed persistent symptoms after one year of follow-up. Given the results of this study, and taking into account the external costs associated with antibiotic resistance, the shorter-term treatment is the antibiotic regimen of first choice.
