She confined herself to bed for 24 days because of the knee pain, weakness and a headache. One month later, she had some decrease in the left-knee swelling and resolution of the headache and weakness. Following her self-confinement, the patient returned to the rheumatologist (Figure 1; second presentation). He reviewed the testing done 1 month previously by the acupuncturist, including the repeat Lyme-disease testing, Schoen, Nat Rev Rheumatol. 2011 Mar;7(3):179–84. for which she was positive (ELISA >5.00; Western Blot, negative for IgM, positive for IgG), and the erythrocyte disease has expanded and Lyme disease is now the most common vector-borne disease in both North America and Europe.5 Lyme disease has characteristic, well-recognized clinical features and is generally classified into early and late stages;6 early disease can be localized or disseminated (Figure 2b).

Scandinavia [30]. The present study in European patients with erythema migrans shows that treatment with doxycycline 100 mg twice daily for 10 days is not less effective than the 15-day Regardless Stupica et treatment. al., CID 2012 May of 21treatment assignment, the outcome was excellent. We found no evidence of objective manifestations of the disease during the 12-month follow-up period. MIGRANS Downloaded from http://cid.oxfordjournals.org/ at Universitaet Zuerich on July 10, 2 Fatigue SYMPTOME 6 MT NACH THERAPIE DES ERYTHEMA [32], but according to some reports it is not related to duration of therapy [33]. The multivariable logistic regression model for repeated measurements indicated that reaching a complete response increased with time from enrollment and that it was higher for males and patients without NOIS at baseline, whereas age, positive results of skin culture, and duration of treatment were not significantly associated with complete response (Table 3). We do not have a reliable explanation for the higher rate of complete response in males. Other findings, which are in accordance with previous results, suggest that subjective longterm sequelae of Lyme borreliosis correlate with greater severity of illness (ie, presence of NOIS) at presentation but not with the duration of the initial antibiotic treatment (when the choice of antibiotic and duration of treatment accord with recommendations) [34]. Our previous study [35] found that patients with positive results of skin cultures had a lower probability of reaching complete response than patients who had negative results of culture (OR, 0.39 [95% CI, .17–.88]; P = .02), whereas in the present study this association was not statistically significant, although the direction of association, albeit weak, was preserved (Table 3). The proportions of patients with complete response were similar in the 2 treatment groups. With the exception of the 14-day time point, when 26.2% of patients had still visible erythema migrans, at all later time points no objective manifestations were found, and those with incomplete response had relatively benign subjective symptoms without functional compromise. The upper limits of the 1-sided 95% CIs for differences in complete response rates between the 2 treatment groups at 14 days, 2 months, 6 months, 12 months, and the last available visit were 16.8, 10.9, 17.9, 9.1, and 4.6 percentage points, respectively. These results indicate that 15 days of treatment could have been associated with only a small improvement in outcome, at most, 4.6–17.9 percentage points (Table 2). Such small potential differences in efficacy are consistent with results of other antibiotic trials involving patients „Patients were asked to refer their spouse, another family member, or a friend whose age was +/−5 years of the patient’s age and who had no history of Lyme borreliosis to serve as a control“ infekttag_2013 2.
