Recurrent meningitis in a child with IgG3 subclass deficiency.
JPMA. the Journal of the Pakistan Medical Association
|September 26, 2014
Summary
Recurrent meningitis, though rare, can be life-threatening. This case highlights a child with two meningitis episodes linked to IgG3 subclass deficiency, suggesting screening for immune deficiencies in such cases.
Area of Science:
- Immunology
- Pediatrics
- Neurology
Background:
- Recurrent meningitis is a rare but serious condition.
- Primary immunodeficiencies increase infection risk and severity.
- Immunoglobulin G (IgG) subclass deficiencies are common, particularly IgG3 deficiency.
Observation:
- A 6-year-old boy experienced two meningitis episodes: aseptic at age 3 and bacterial at age 4.
- The patient was diagnosed with IgG3 subclass deficiency.
- This case involved recurrent aseptic and bacterial meningitis within a year.
Findings:
- The case demonstrates a rare occurrence of both aseptic and bacterial meningitis recurrence in a child with IgG3 subclass deficiency.
- IgG3 subclass deficiency is the most common IgG subclass deficiency, often linked to recurrent infections.
Implications:
- Screening children with recurrent meningitis for primary immunoglobulin or complement deficiencies is recommended.
- Early diagnosis and management of immunodeficiencies can prevent severe infections like recurrent meningitis.

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

8
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...

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

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...

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

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...
