Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective, multicenter, observational clinical registry of adult patients with acute infectious meningitis across approximately 30 public and private hospitals in Brazil. The study will include adults, 18 years old and older, with suspected acute infectious meningitis. Data will be collected during hospitalization and post-discharge to evaluate clinical management, treatment and short and long-term outcomes. The study aims to generate real-world evidence on current practices and outcomes to support improvements in national care protocols.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a middle-income real-world prospective clinical registry study. Clinical and laboratory data will be collected during hospitalization and follow-up visits after discharge.

Data collection will include empirical antibiotic therapy timing and type, time from hospital admission to antibiotic's first dose, corticosteroid therapy initiation, vaccination status per the Brazilian National Immunization Program, neurological sequelae and access to specialized rehabilitation services post-discharge.

Primary outcomes will be all-cause mortality, length of hospital stay, rate of re- hospitalization and sensorineural hearing loss incidence.

Secondary outcomes will be etiology-specific mortality, functional outcomes (measured by modified Rankin Score and Barthel Index Brazilian version), guideline-based therapies by etiology, neurological sequelae incidence stratified by etiology (e.g., motor deficits, cerebrovascular complications) , serious adverse events and access to rehabilitation.

Findings will be used to inform public health system and clinical care in Brazil.
