Abstract


Objective To investigate the efficacy of cluster therapy in the treatment of severe intracranial infection. Methods The clinical data of 43 patients with severe intracranial infection in Shenzhen University General Hospital and Shenzhen Second People's Hospital from July 2020 to June 2023 were retrospectively analyzed. Patients with intracranial infection were treated with cluster therapy: systemic broad⁃spectrum antibiotics were used at first; cerebrospinal fluid was obtained by multiple drainage routes for routine and biochemical testing, and then cultured and undertook next ⁃ generation sequencing (NGS); head/chest CT and brain MRI plain and enhanced scan were performed; after the NGS results were reported, precisely adjust the drug treatment according to the infection pathogen; sequentially use different drainage protocols of infected cerebrospinal fluid. Patients with severe intraventricular inflammation were treated with ventriculoscope (flexible endoscope) irrigation and fistula; cerebrospinal fluid, microbial culture and whole blood test for infection indicators were regularly extracted for laboratory test, and the type and dosage of antibiotics were adjusted one week after the indicators returned to normal, and the treatment effect of patients was judged comprehensively according to blood, cerebrospinal fluid, imaging results and clinical signs of infection. Results Sixteen patients were administered a broad ⁃ spectrum antibiotic regimen consisting of meropenem and vancomycin. Cerebrospinal fluid analysis revealed that 12 cases (27.91%) were culture⁃positive for microbial organisms (bacteria, fungi, viruses), while 35 cases (81.40%) yielded positive results in NGS. Upon identification of the pathogen via NGS, 15 cases were switched to targeted, sensitive antibiotics, with 12 cases exhibiting notable improvements in symptoms, and 3 cases demonstrating no significant changes. A total of 27 patients (62.79%) underwent surgical intervention, including 7 patients (16.28%) who underwent abscess puncture drainage, 6 patients (13.95%) who received Ommaya sac implantation, 11 patients (25.58%) who underwent external ventricular drainage (8 of whom also underwent ventriculoscopic irrigation and ventriculostomy), and 3 patients (6.98%) who were treated with lumbocisterna drainage. The length of hospitalization was 30 (19, 57) d. The 37 cases (86.05%) were successfully cured, while 6 cases (13.95%) died. Conclusions The cure rate of patients with severe intracranial infection was significantly improved after cluster therapy, and early initiation of cluster therapy can significantly improve the prognosis of patients, which is worthy of clinical application.
