LTT-Validity in diagnosis and therapeutical decision making of neuroborreliosis: a prospective dual-centre study.
Objectives: The key objective of this study was to assess the validity of a commercially available in-house Lymphocyte Transformation Test (LTT) as a diagnostic parameter and indicator of disease activity/therapeutic efficacy in the context of Lyme neuroborreliosis (LNB).
Methods: A prospective dual-centre study was conducted from 05/14 - 01/18. With respect to Borrelia-LTT a comparison was made between patients suffering from confirmed acute LNB and patients being affected by inflammatory neurologic diseases, defining the control group: Bell's palsy, viral meningitis, herpes zoster, Guillain-Barré-Syndrome and Encephalomyelitis disseminate. Furthermore, we investigated the LTT within the LNB group at the time of admission and again 12 weeks (+/- one week) later - after appropriate antibiotic treatment.
Results: Cases included 15 patients with LNB and 58 participants in the control group. With regard to Borrelia-LTT we calculated a low sensitivity of 40% and a moderate specificity of 91% for LNB. Additionally, LTT-levels three months after adequate antibiotic therapy did not correlate with the therapeutic response of LNB patients.
Conclusions: The present study shows that LTT is neither appropriate for LNB detection nor suitable as a follow-up marker.
期刊介绍：
Infection is a journal dedicated to serving as a global forum for the presentation and discussion of clinically relevant information on infectious diseases. Its primary goal is to engage readers and contributors from various regions around the world in the exchange of knowledge about the etiology, pathogenesis, diagnosis, and treatment of infectious diseases, both in outpatient and inpatient settings.
The journal covers a wide range of topics, including:
Etiology: The study of the causes of infectious diseases.
Pathogenesis: The process by which an infectious agent causes disease.
Diagnosis: The methods and techniques used to identify infectious diseases.
Treatment: The medical interventions and strategies employed to treat infectious diseases.
Public Health: Issues of local, regional, or international significance related to infectious diseases, including prevention, control, and management strategies.
Hospital Epidemiology: The study of the spread of infectious diseases within healthcare settings and the measures to prevent nosocomial infections.
In addition to these, Infection also includes a specialized "Images" section, which focuses on high-quality visual content, such as images, photographs, and microscopic slides, accompanied by brief abstracts. This section is designed to highlight the clinical and diagnostic value of visual aids in the field of infectious diseases, as many conditions present with characteristic clinical signs that can be diagnosed through inspection, and imaging and microscopy are crucial for accurate diagnosis. The journal's comprehensive approach ensures that it remains a valuable resource for healthcare professionals and researchers in the field of infectious diseases.
