Lyme Disease Discovery Could Lead to Earlier Diagnosis and Treatment
Summary
Scientists at Tufts University have found specific immune molecules that appear early in Lyme disease infections and may help doctors diagnose the disease sooner. These molecules could also help identify patients who have ongoing symptoms after treatment, potentially improving testing and care for Lyme disease.Key Facts
- Lyme disease is caused by a bacterium called Borrelia burgdorferi.
- Current tests find antibodies that take weeks to appear and can stay long after infection is gone, making diagnosis difficult.
- Researchers discovered antibodies against certain fats (lipids) that show up earlier in infection.
- Three lipid-related antibodies were found at higher levels during Lyme infection; two of these (αPA and αPS) appeared even before standard tests turned positive.
- Elevated αPS antibody levels were linked to patients with lasting symptoms after treatment.
- These antibodies are less likely to be found in other diseases that mimic Lyme symptoms.
- The study used blood samples from 199 Lyme disease patients and compared them to healthy volunteers and individuals with similar diseases.
- More research is needed before these findings can be turned into a new test for Lyme disease.
