Evaluation of selected variables to determine if any had predictive value for, or correlated with, residual symptoms at approximately 12 months after diagnosis and treatment of early Lyme disease.

Subjective symptoms may persist after antibiotic treatment of patients with erythema migrans. Selected baseline variables were evaluated to determine if any correlated with symptom persistence to 12 months (PTLDS). Tingling or an abnormal skin sensation were reported by 5 (71.

Patients with Erythema Migrans: Characterizing the Impact of Initiation of Antibiotic Therapy Prior to Study Enrollment.

Erythema migrans is the most common clinical manifestation of Lyme disease, with concomitant subjective symptoms occurring in ∼65% of cases in the United States. We evaluated the impact of having been started on antibiotic treatment before study enrollment on 12 particular symptoms for 38 subjects with erythema migrans versus 52 untreated subjects. There were no significant differences in the frequency of having at least one symptom or in the symptom severity score on study entry.

Prospective Evaluation of the Frequency and Severity of Symptoms in Lyme Disease Patients With Erythema Migrans Compared With Matched Controls at Baseline, 6 Months, and 12 Months.

Background: Erythema migrans is the most common clinical manifestation of Lyme disease. Despite antibiotic therapy, typically at least 10% of adult patients with erythema migrans experience persistence of at least 1 subjective symptom for ≥6 months (posttreatment Lyme disease symptoms [PTLDS]).

Methods: This study was designed to determine whether the frequency and severity (based on a visual analogue scale) of 12 particular symptoms in patients with erythema migrans (n = 52) differed from matched control subjects (n = 104) followed prospectively for 12 months.
