For all patients in the series, except for 2 cases in which prolonged treatment was administered, the therapy applied was the acute Q fever therapy. However, a number of patients who were asymptomatic by the time the serological results were available were not treated. None of the patients developed endocarditis.

However, although 6% of cases of endocarditis by <span class="elsevierStyleItalic">Coxiella</span> can be asymptomatic,<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">5</span></a> the lack of clinical data over the course of the highly prolonged progression in our series is surprising.</p><p id="par0120" class="elsevierStylePara elsevierViewall">A number of authors have proposed that phase I IgG antibody titers ≥1:6400 should be considered a major criterion of endocarditis and that titers <1:6400 but ≥1:800 such be considered a minor criterion, thereby achieving a positive predictive value of 75% for endocarditis.<a class="elsevierStyleCrossRefs" href="#bib0180"><span class="elsevierStyleSup">13,21</span></a> The definitive diagnosis of endocarditis requires isolates from the surgically removed heart valve (cultures, CRP or immunohistochemistry) or, lacking valve tissue, the presence of clinical symptoms compatible with chronic infection/valve dysfunction along with other major or minor clinical criteria.

The factors that could justify the non-progression to endocarditis in our patients include the fact that these were young individuals in whom the prevalence of prior valvular heart disease was low, given that this prevalence is estimated at 0.7% in patients younger than 54 years.<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">22</span></a> Surprisingly, in the French study, the prevalence of valvular heart disease at this age reached 45%.

Many of our patients did not therefore undergo extended serologic follow-up or echocardiographic studies. Thus, cases of subclinical endocarditis might have gone undiagnosed. However, none of the patients were carriers of valvular or vascular prosthesis or required valve surgery over the course of their evolution. Moreover, CRP tests in blood were not conducted for all patients, which could have detected cases of asymptomatic chronic Q fever (estimated sensitivity of 33–64%).<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">23</span></a></p><p id="par0135" class="elsevierStylePara elsevierViewall">Based on our results, it appears that the detection in asymptomatic patients of phase I IgG antibody levels ≥1:1024 in the first 3 months after an episode of acute Q fever, even when prolonged antibiotherapy is not provided, is not associated with progression to endocarditis. The diagnostic–therapeutic approach after an episode of acute Q fever should be based mainly on the established risk factors or the presence of clinical symptoms.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Conflicts of interest</span><p id="par0140" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflicts of interest.</p></span></span>"
