Design outcomes

Primary

MeasureTime frameDescription
Number (frequency) of patients with objective manifestations of Lyme borreliosis or subjective Lyme borreliosis-associated/post-Lyme borreliosis symptomsOne year follow-upAt each visit physical examination wil be performed and clinical signs indicating objective manifestations of Lyme borreliosis, such as erythema migrans, will be searched for and documented. At each visit patients will be asked an open question about any health-related symptoms that had newly developed or worsened since the onset of erythema migrans. If these symptoms will have no other known medical explanation, they will be regarded as Lyme borreliosis-associated constitutional symptoms at enrolment or post-Lyme borreliosis symptoms at follow-up.

Secondary

MeasureTime frameDescription
Number (frequency) of patients with nonspecific symptomsOne year follow-upAt each visit patients will be asked to complete a written questionnaire asking whether they had had any of eight non-specific symptoms (fatigue, arthralgias, headache,myalgias, paraesthesias, memory difficulties, concentration difficulties and irritability) within the preceding week.
