Safety and Efficacy of Ventricular Irrigation for Ventriculitis

Central Nervous System Infections Clinical Trial

Official title: Safety and Efficacy of Ventricular Irrigation for Ventriculitis: a Randomized Controlled Trial

Status Not yet recruiting

Clinical Trial Summary

Ventriculitis is a severe infectious disease of the central nervous system with diverse etiologies. Currently, the treatment for ventriculitis is challenging, with poor prognosis. The mortality rate of ventriculitis is generally reported to be higher than 30%, with the highest reaching over 75%. Even among survivors, over 60% suffer from a variety of neurological sequelae, including cognitive impairment, gait disturbances, paralysis, behavioral disorders, and epilepsy.

Currently, treatments for ventriculitis recommended by guidelines primarily focus on the selection and administration of antibiotics, while the effects of surgical interventions have not been fully elucidated. In recent years, several studies have explored the use of ventricular irrigation in ventriculitis, indicating that ventricular irrigation techniques may accelerate the control of ventricular infection, mitigate damage to the central nervous system caused by infections, improve the prognosis of ventriculitis, and reduce complications such as hydrocephalus. However, current studies are still relatively scarce, and mostly case reports and retrospective studies. High-quality evidence is still lacking for the application of ventricular irrigation in ventriculitis.

This multicenter randomized controlled trial aims to explore the safety and effectiveness of ventricular irrigation compared to conventional treatment for severe ventriculitis, analyze the effectiveness of ventricular irrigation across different pathogen subgroups, and investigate independent risk factors for different prognostic states in patients with severe ventriculitis.

Clinical Trial Description

Ventriculitis is a severe infectious disease of the central nervous system with diverse etiologies. Ventriculitis is associated not only with community-acquired diseases but also, more importantly, with invasive clinical procedures, including craniotomy, external ventricular drainage (EVD), lumbar cistern drainage, V-P shunt, and deep brain stimulation, among others. Depending on the diagnostic criteria, the incidence of post-neurosurgery ventriculitis ranges from approximately 5% to 20%, with risk factors including age, prolonged placement of EVD, and intracranial hemorrhage. Besides, the pathogens leading to ventricular infection are also diverse, with the main pathogens including coagulase-negative Staphylococci, Staphylococcus aureus, Propionibacterium acnes, and Gram-negative bacilli.

The treatment for ventriculitis is challenging, with poor prognosis. Under currently widely adopted treatment strategies, the mortality rate of ventriculitis is generally reported to be higher than 30%, with the highest reaching over 75%. Even among survivors, over 60% suffer from a variety of neurological sequelae, including cognitive impairment, gait disturbances, paralysis, behavioral disorders, and epilepsy. This imposes significant burden on families and society. Therefore, how to further improve prognosis of ventriculitis, and reduce the mortality and disability rates, remains to be addressed.

Currently, treatments for ventriculitis recommended by guidelines primarily focus on the selection and administration of antibiotics, while the effects of surgical interventions have not been fully elucidated. As an infectious disease, surgical procedures such as irrigation and drainage have the potential to play a role in reducing infection and improving prognosis for ventriculitis.

In recent years, several studies have explored the use of ventricular irrigation in ventriculitis, indicating that ventricular irrigation techniques (including endoscopic ventricular irrigation and dual catheter irrigation techniques) via replacing saline and draining purulent cerebrospinal fluid (CSF), may accelerate the control of ventricular infection, mitigate damage to the central nervous system caused by infections, improve the prognosis of ventriculitis, and reduce complications such as hydrocephalus. However, current studies are still relatively scarce, and mostly case reports and retrospective studies. A prospective controlled study that included 33 patients with ventriculitis divided participants into groups receiving ventricular irrigation treatment and conventional treatment. The study results showed that compared to conventional treatment, ventricular irrigation resulted in higher mRS prognosis scores, shorter hospital stays, and the study also showed a trend towards reduced mortality in irrigation group. However, this study was limited by a small sample size, limited study endpoints and not strictly randomized. Currently, high-quality evidence is still lacking for the application of ventricular irrigation in ventriculitis.

Based on these considerations, this multicenter randomized controlled trial aims to explore the safety and effectiveness of ventricular irrigation compared to conventional treatment for severe ventriculitis, analyze the effectiveness of ventricular irrigation across different pathogen subgroups, and investigate independent risk factors for different prognostic states in patients with severe ventriculitis. ;
