Aim: The aim of this thesis is to comprehensively investigate the clinical presentation, neuroimaging findings, and outcomes of children admitted with acute febrile encephalopathy in a tertiary care hospital.
Objectives: Primary objective - To study the clinical profile and etiology of acute febrile encephalopathy in children. Secondary objective - To evaluate factors associated with mortality and neurologic sequelae on discharge. Research questions 1. What are the common clinical features observed in children admitted with acute febrile encephalopathy, and how do these presentations vary across different etiological factors? 2. What are the neuroimaging findings seen in children with acute febrile encephalopathy, and how do these findings correlate with clinical symptoms and outcomes? 3. What are the predominant etiological factors contributing to acute febrile encephalopathy in pediatric patients, and what is the distribution of infectious versus non-infectious causes? 4. What are the short-term and long-term clinical outcomes of children admitted with acute febrile encephalopathy, including mortality rates, neurological sequelae, and functional disability? 5 .Are there identifiable biomarkers in blood, cerebrospinal fluid, or neuroimaging studies that correlate with disease severity, treatment response, and long-term prognosis in children with acute febrile encephalopathy? Selection Criteria Inclusion criteria 1. Children aged more than 28 days and less than 12 years affected with acute febrile encephalopathy. Exclusion criteria 1. Cases of neurodevelopmental delay, inborn errors of metabolism. 2. Known cases of febrile seizures or seizure disorders, hypoxic ischemic encephalopathy and brain tumors. Materials and methods Ethics- Approval from IEC will be obtained prior to the commencement of the study. Consent- Written, informed consent from caregivers of study participants will be obtained as per the ICMR National Ethical guidelines for Biomedical and Health Research involving Human Participants 2017. Study type – Single centre, observational cross sectional study. Confidentiality – The personal details of participants will be kept confidential and will not be mentioned in the study. Setting- Ward and ICU of Department of Paediatrics . Study duration – 15 months for data collection and 3 months for analysis.
Expected outcomes The expected outcomes of a research study on the clinical, imaging profile, and outcome of children admitted with acute febrile encephalopathy in a tertiary care hospital may include: 1. Comprehensive Understanding of Clinical Presentation: Identification and documentation of common clinical features and symptomatology associated with acute febrile encephalopathy in pediatric patients, leading to improved recognition and diagnosis of the condition. 2. Insight into Neuroimaging Findings: Characterization of neuroimaging findings, including structural abnormalities, inflammatory changes, and infectious processes affecting the central nervous system, providing insights into the underlying pathophysiology and aiding in differential diagnosis. 3. Etiological Insights: Determination of the predominant etiological factors contributing to acute febrile encephalopathy in children, including infectious and non-infectious causes, which may inform targeted diagnostic evaluations and therapeutic interventions. 4. Clinical Outcome Analysis: Evaluation of short-term and long-term clinical outcomes, including mortality rates, neurological sequelae, cognitive impairment, and functional disability, facilitating prognostication and guiding follow-up care and rehabilitation strategies. 5. Identification of Predictive Biomarkers: Discovery of potential biomarkers in blood, cerebrospinal fluid, or neuroimaging studies that may serve as indicators of disease severity, treatment response, and long-term prognosis, enabling personalized management approaches and early intervention strategies. 6. Enhanced Clinical Management: Integration of research findings into clinical practice to improve diagnostic accuracy, optimize therapeutic strategies, and ultimately enhance patient care and outcomes in pediatric acute febrile encephalopathy cases. Overall, the expected outcomes of this research study aim to advance our understanding of acute febrile encephalopathy in children, leading to improved diagnostic and management strategies and ultimately better outcomes for affected patients.
