Viral Meningitis

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Arboviral Encephalitis

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Cryptococcal Meningitis

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Encephalitis l: Introduction

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Summary

Diagnosing neurological infections efficiently is crucial. Viral neuro-infections were diagnosed faster with fewer tests, unlike those in immunosuppressed patients requiring longer hospital stays.

Area of Science:

Neurology
Infectious Diseases
Diagnostic Medicine

Background:

Neurological infections pose significant morbidity and mortality risks.
Efficient diagnosis is critical for timely and appropriate patient management.
Tertiary referral centers play a key role in managing complex neuroinfectious cases.

Purpose of the Study:

To evaluate the diagnostic approach for definitive neurological infections.
To assess time to diagnosis, number of tests ordered, and diagnostic modalities.
To identify factors influencing diagnostic efficiency and patient outcomes.

Main Methods:

Retrospective review of 111 confirmed neurological infection cases (2010-2018).
Definitive diagnosis criteria included positive cerebrospinal fluid (CSF) PCR/antigen, CSF culture, CSF antibody, serology, or pathology.
Analysis of time to diagnosis, tests ordered, and patient factors like ICU admission and hospitalization length.

Main Results:

Etiologic diagnosis averaged 3.1 days with 27.7 tests per workup.
Viral neuro-infections showed shorter diagnosis times, fewer tests, and shorter hospitalizations (P < .05).
Immunosuppression was linked to longer hospitalizations irrespective of infection type (P < .001).

Conclusions:

Optimizing diagnostic strategies for neurological infections is essential.
Understanding etiological differences, like viral vs. other pathogens, can improve efficiency.
Patient factors such as immunosuppression status significantly impact clinical course and resource utilization.
