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...

Encephalitis ll: Pathophysiology

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

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...

Poliomyelitis

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Rheumatic Heart Disease I: Introduction

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Summary

Central nervous system (CNS) involvement is uncommon in relapsing polychondritis. This case highlights encephalitis as a rare CNS manifestation, emphasizing prompt corticosteroid treatment for suspected cases.

Background:

Relapsing polychondritis (RP) is a rare systemic autoimmune disease characterized by progressive cartilage destruction.
Central nervous system (CNS) manifestations are infrequent complications of relapsing polychondritis.
Encephalitis, an inflammation of the brain, is an exceptionally rare presentation in RP patients.

Purpose of the Study:

To report a rare case of encephalitis associated with relapsing polychondritis.
To highlight the importance of early recognition of CNS involvement in RP.
To emphasize the efficacy of prompt corticosteroid therapy in managing neurological complications of RP.

Main Methods:

Case report detailing the clinical presentation, diagnostic process, and treatment of a patient with relapsing polychondritis and encephalitis.
Review of the patient's initial symptoms including auricular and tracheal chondritis.
Assessment of neurological symptoms and response to high-dose corticosteroid therapy.

Main Results:

The patient initially presented with chondritis of the ears and trachea.
Encephalitis developed subsequently, presumed to be due to vasculitis.
Neurological symptoms showed dramatic improvement following pulse corticosteroid therapy.

Conclusions:

Early identification of central nervous system involvement in relapsing polychondritis is crucial for timely intervention.
High-dose corticosteroid therapy should be administered promptly to patients suspected of having CNS complications from RP.
This case underscores the potential for severe neurological sequelae in relapsing polychondritis and the effectiveness of immunosuppressive treatment.
