Evaluating neuropeptide levels in meningitis patients

Evaluation of the Levels of Calcitonin Gene-related Peptide and Substance P in Patients With Post-operative Meningitis

Observational Akdeniz University · NCT06510751

This study is testing if certain proteins in the blood and spinal fluid can help doctors better diagnose and understand the outcomes for adults with meningitis related to external ventricular catheters in the ICU.

What this trial studies

This observational study focuses on adult patients with suspected meningitis related to external ventricular catheters in the Intensive Care Unit. It aims to analyze the levels of calcitonin gene-related peptide (CGRP) and substance P in blood and cerebrospinal fluid (CSF) samples taken at various stages of the disease. The study will also assess clinical parameters such as the patient's state of consciousness, organ failure, and infection status, alongside routine laboratory tests and imaging findings. The goal is to identify reliable biomarkers that can improve the diagnosis and prognosis of postoperative meningitis.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are in the Intensive Care Unit with suspected meningitis related to CSF drainage systems.

Not a fit: Patients under 18 years of age or those with suspected meningitis who have not undergone neurosurgical operations and lack a CSF drainage catheter will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and prognostic tools for patients with meningitis, potentially reducing mortality and morbidity rates.

How similar studies have performed: There are very few studies investigating CGRP and substance P levels in this context, making this approach relatively novel.
