Brief Summary

Lyme arthritis resolves with appropriate antimicrobial treatment in a majority of patients, but 10-20% of patients develop antibiotic-refractory Lyme arthritis with prolonged arthritis symptoms and treatment courses. Excessive up-regulation of the inflammatory process has been shown in patients with antibiotic-refractory Lyme arthritis. The over-expressed pro-inflammatory cell mediators are downstream of NSAID inhibition, which would suggest initial inflammatory inhibition may be beneficial in these patients. While NSAIDs are known to reduce pro-inflammatory cell mediators early in the course of inflammation, research has shown that there are other cytokines that play a role in the healing after inflammation that are also inhibited by NSAIDs, and that NSAID use can delay healing. It is not known if scheduled NSAID therapy will reduce, increase, or have no effect on the occurrence of refractory Lyme arthritis cases. The hypothesis of the study is that prescribing scheduled NSAIDs at the time of diagnosis of Lyme arthritis can prevent the development of the excessive inflammatory phase and decrease the number of patients with antibiotic-refractory Lyme arthritis, or at least decrease the duration of persistent Lyme arthritis symptoms. The pilot study design randomizes patients to scheduled NSAIDs, scheduled acetaminophen, or scheduled NSAIDs x 1 week than acetaminophen. Primary outcomes are duration of arthritis symptoms, number of refractory cases, side effects and compliance.

Outcome Measures

Primary Outcomes (5)

  • Joint Pain Reported by Serial Visual Analog Scale (VAS) for Pain Via Text Surveys

    0-100 scale (no pain to worst pain - higher score, worse outcome), slide bar in text survey

    days 0(enrollment), 1, 3, 7, 10, 14, 21, 28, 60 the VAS score will be collected

  • Joint Redness Reported by Serial Visual Analog Scale for Joint Redness Via Text Surveys

    0-100 scale (no redness to maximal redness- higher score, worse outcome), slide bar in text survey

    days 0 (enrollment), 1, 3, 7, 10, 14, 21, 28, 60 the VAS score for join redness will be collected

  • Joint Movement Reported by Serial Visual Analog Scale for Joint Movement Via Text Surveys

    0-100 scale (no joint movement to normal joint movement- higher score, better outcome), slide bar in text survey

    days 0 (enrollment), 1, 3, 7, 10, 14, 21, 28, 60 the VAS score for joint movement will be collected

  • Overall Function Reported by Serial Visual Analog Scale for Overall Function Via Text Surveys

    0-100 scale (severely impaired function to normal function- higher score, better outcome), slide bar in text survey

    days 0 (enrollment), 1, 3, 7, 10, 14, 21, 28, 60 the VAS score will be collected

  • Time to Complete Symptom Resolution as Collected by a Yes/no Question on the Text Survey

    If patient answers yes to symptoms completely resolved, the time frame from enrollment will be the days to symptom resolution

    Symptom resolution recorded (days 0, 1, 3, 7, 10, 14, 21, 28, 60) once they enter "yes" to symptoms completely resolved

Secondary Outcomes (4)

  • Medication Compliance as Determined by Question in Serial Text Survey

    days 1, 3, 7, 10, 14, 21, 28, 60 (collected until symptom resolution)

  • The Number of Participants With Reported Medication Side Effects as Determined by Question in Serial Text Survey

    days 1, 3, 7, 10, 14, 21, 28, 60 (collected until symptom resolution)

  • The Number of Participants Who Reported Taking Other Medications as Determined by Question in Serial Text Survey

    days 1, 3, 7, 10, 14, 21, 28, 60 (collected until symptom resolution)

  • Number of Participants Who Reported Fever as Determined by Question in Serial Text Survey

    days 0 (enrollment), 1, 3, 7, 10, 14, 21, 28, 60 (collected until symptom resolution)

Other Outcomes (1)

  • Need for Further Care as Determined by Medical Record Review as Mean Number of Visits in the System for Lyme Arthritis Symptoms During Each Time Frame

    30 days, 60 days, 120 days, 1 year
