Lyme Disease Biobank (LDB) enrolls participants with signs and symptoms of early Lyme disease (LD) from endemic areas and makes samples available to researchers developing more accurate diagnostics. From 2014 to 23, 466 cases and 367 controls were enrolled on Long Island, NY, and in Central Wisconsin.
This study included 253 LDB participants who provided samples from an initial and a convalescent blood draw. Serologic testing, including a first-tier enzyme immunoassay and IgM and IgG immunoblotting, was performed on all samples; blots were interpreted using CDC criteria.
At the first draw, 34% of samples from participants presenting with erythema migrans (EM) > 5 cm were positive by CDC's standard two-tiered testing (STTT) algorithm. IgG seroconversion was rare, only 4% of samples demonstrated seroconversion. While the majority of participants (78%) reported no LD symptoms at the second draw, 22% reported ongoing symptoms; the most common being joint pain, fatigue, and muscle pain. Only 35% of participants with ongoing symptoms reported seeing their provider about their symptoms.
These results provide additional evidence that STTT is insensitive in early LD and seroconversion is rare after antibiotics. More than one-fifth of participants initially prescribed antibiotics reported ongoing LD symptoms. Therefore, healthcare professionals treating patients with early LD are encouraged to follow-up with their patients, determine whether they continue to experience symptoms, and consider immediate antibiotic re-treatment as appropriate. Early diagnosis, treatment, and follow-up of early LD patients has the potential to improve outcomes and reduce the burden of LD in the US.
莱姆病生物样本库(LDB)招募来自流行地区的早期莱姆病(LD)有体征和症状的参与者,并向开发更准确诊断方法的研究人员提供样本。2014年至2023年期间,在纽约长岛和威斯康星州中部招募了466例病例和367例对照。
本研究纳入了253名LDB参与者,他们提供了首次和恢复期采血的样本。对所有样本进行了血清学检测,包括一级酶免疫测定以及IgM和IgG免疫印迹;印迹结果根据美国疾病控制与预防中心(CDC)标准进行解读。
首次采血时,出现直径>5厘米游走性红斑(EM)的参与者样本中,有34%通过CDC的标准两级检测(STTT)算法呈阳性。IgG血清转化很少见,只有4%的样本显示血清转化。虽然大多数参与者(78%)在第二次采血时报告没有LD症状,但22%报告仍有症状;最常见的是关节疼痛、疲劳和肌肉疼痛。有持续症状的参与者中只有35%报告就其症状咨询过医疗服务提供者。
这些结果进一步证明,STTT在早期LD中不敏感,抗生素治疗后血清转化很少见。最初接受抗生素治疗的参与者中,超过五分之一报告仍有LD症状。因此,鼓励治疗早期LD患者的医疗专业人员对患者进行随访,确定他们是否仍有症状,并在适当情况下考虑立即重新使用抗生素治疗。早期LD患者的早期诊断、治疗和随访有可能改善治疗效果并减轻美国LD的负担。
