A new study found that most of the pediatric patients who were treated for Lyme disease had complete recovery within 6 months including those who experienced post-treatment Lyme disease (PTLD) syndrome. The study results were published in the journal Pediatric Research.
Children and teenagers frequently contract Lyme disease. Despite the effectiveness of antibiotic therapy, some individuals continue to experience symptoms after treatment, either with or without functional impairment. Hence researchers from The George Washington University School of Medicine and Health Sciences, Washington, DC, USA conducted a study to assess the long-term outcome of pediatric patients with Lyme disease and evaluated the case definition of post-treatment Lyme disease (PTLD) syndrome.

Nearly 102 children with confirmed Lyme disease diagnosed 6 months—10 years before enrollment (M = 2.0 years) were included. Electronic health records were used to extract information on Lyme diagnosis and treatment and parent report was used to identify the presence, duration, and impact of symptoms after treatment. The health-related quality of life, physical mobility, fatigue, pain, and cognitive impact were assessed using validated questionnaires filled out by the participants.

Key findings:
Despite the variation in the time to full resolution, most parents reported their child’s symptoms resolved completely.
About 22 parents (22%) reported the presence of at least one persistent symptom >6 months post-treatment, 13 without functional impairment (PTLD symptoms), and 9 with functional impairment (PTLD syndrome).
Children with PTLD syndrome had lower parent-reported Physical Summary scores and a greater likelihood of elevated fatigue.
Thus, the majority of kids with Lyme disease, including those who initially fit the PTLD syndrome criteria, had complete symptom remission. Researchers suggested that effective communication is required on recovery rates and typical symptoms that could remain after therapy.
